In the installation of card support 400, the user will carry the card support 400 of smart card to push away to within casing 600 from the perforation, because perforation and first installation space set up relatively, consequently in card support 400 can extend to within the first installation space through the perforation, this in-process, under the effect with the outdoor power, card support 400 can jack up elastic bulge 211, move to the position relative with elastic bulge 211 until joint recess 430, final elastic bulge 211 and the cooperation of joint recess 430 elastic positioning, first installation space is installed to final realization card support 400, meanwhile, application of force portion 410 can contact with detection part 540, thereby confirm that card support 400 installs in place.

In the process of detaching the card holder 400, a user uses the thimble 700 to penetrate through the thimble hole to push the first end of the shift lever 530, so that the shift lever 530 rotates, the first end of the shift lever 530 rotates towards the direction far away from the thimble hole, because the second end of the shift lever 530 is opposite to the stressed portion 420, and the rotation center of the shift lever 530 is located between the two ends of the shift lever, therefore, in the rotating process of the shift lever 530, the second end of the shift lever 530 rotates towards the direction close to the through hole, finally, the purpose of pushing the card holder 400 to extend out of the shell 600 at least partially through the through hole can be achieved by pushing the stressed portion 420, in the process, the second end of the shift lever 530 applies the pushing force on the stressed portion 420, and the elastic force between the elastic protrusion 211 and the card holder recess 430 can be overcome, so that the card. Finally, the user may pull the card holder 400 away. In the process that the card holder 400 moves out of the housing 600, the force application part 410 is separated from the detection part 540, thereby determining that the card holder 400 is in a detached state.

The electronic device disclosed in the embodiment of the present application improves the structure of the electronic device in the related art, and the shift lever 530 and the detection portion 540 are disposed in the second installation space formed by the first cover 510 and the second cover 520, and the card holder 400 is designed to have the structure including the force application portion 410 and the force receiving portion 420, so that the force application portion 410 can be matched with the detection portion 540, and the force receiving portion 420 is matched with the second end of the shift lever 530, thereby realizing the functions of ejecting and state detection of the card holder 400. Compared with the independent design of the detection mechanism for detecting the mounting state of the card holder and the ejection mechanism for driving the card holder to be detached in the related art, the detection ejection mechanism in the electronic equipment disclosed by the embodiment of the application integrates the detection mechanism and the ejection mechanism, is convenient to mount, can reduce the occupied space, and is further favorable for reducing the occupied space of the detection ejection mechanism 500 on the circuit board 100.

As described above, the detection ejection mechanism 500 is disposed on the circuit board 100, and specifically, the detection ejection mechanism 500 may be disposed at a plurality of positions on the circuit board 100 as long as the working requirements thereof can be satisfied. In an alternative scheme, the edge of the circuit board 100 facing the through hole may be provided with a notch, the detection ejection mechanism 500 may be disposed in the notch, and the card holder 400 covers at least a portion of the detection ejection mechanism 500. In the related design scheme, the circuit board 100 is close to the through hole, and the area covered by the card holder 400 is difficult to be utilized, and due to the influence of the card holder 400, the electronic component cannot be installed in the area, so that the design mode can make full use of the area which is close to the through hole and covered by the card holder 400 on the circuit board 100, and further the space utilization rate of the circuit board 100 can be improved, and further the detection ejection mechanism 500 can be prevented from occupying more other areas which are not covered by the card holder 400 on the circuit board 100.

In the embodiment of the present application, the holder 400 may have a center line extending along a penetrating direction of the through hole, and a portion of the force-receiving portion 420 contacting the second end of the shift lever 530 may be located on the center line. In the process of detaching the card holder 400, the second end of the shift lever 530 can apply a force to the center line of the card holder 400, so that the card holder 400 is stressed more evenly in the detaching process, and the phenomenon that the card holder 400 is clamped with the housing 600 due to unbalanced stress is avoided.

In this application embodiment, the structure of card support 400 can be manifold, and card support 400 can hold in the palm cap 400a, card support slot frame 400b and card support layer board 400c including the card, and card support slot frame 400b supports on card support layer board 400c, and card support cap 400a links to each other with card support slot frame 400b is fixed, and card support slot frame 400b and card support layer board 400c all can be the metallic structure spare, and is specific, and card support cap 400a can be through welding or the mode fixed connection who moulds plastics with card support slot frame 400 b. The card slot bracket 400b and the card slot bracket 400c can form a card slot for receiving a smart card. The card holder cap 400a is fitted to the through hole of the case 600 after the card holder 400 is mounted in place, and blocks the through hole. The card support 400 with the structure has the advantage of high strength, and the deformation of the card support 400 after stress can be relieved, so that the driving of the detection ejection structure 500 to the card support 400 can be well ensured.

As described above, the card holder 400 may include the force application portion 410 and the force receiving portion 420, and in an alternative scheme, the card holder supporting plate 400c may include the force application portion 410 and the force receiving portion 420, and specifically, the card holder supporting plate 400c is located at the bottom of the whole card holder 400, so as to be advantageously matched with the corresponding portion of the detection ejection mechanism 500 covered by the card holder 400. Specifically, the card support plate 400c may be a unitary structural member, for example, the card support plate 400c is a metal cut piece formed by a cutting process (e.g., CNC machining).

As described above, removal of card holder 400 requires the user to grasp thimble 700 and push first end of lever 530. In the operation process, when a user passes the thimble 700 through the thimble hole to push the first end of the shift lever 530, the end of the thimble 700 in contact with the shift lever 530 may slide to stab devices in other areas of the electronic device, based on which, in an alternative scheme, the surface of the first end of the shift lever 530 facing the thimble hole may be provided with a limit groove 531, a notch of the limit groove 531 may face the thimble hole, a bottom wall of the limit groove 531 facing the notch is a thimble action surface, the thimble 700 may apply a pushing force to the thimble action surface, in the process that the thimble 700 pushes the first end of the shift lever 530 to rotate, the end of the thimble 700 in contact with the shift lever 530 may extend into the limit groove 531 and be in limit fit with the limit groove 531, and under the limit action of the limit groove 531, an adverse effect caused by the end sliding of the thimble 700 may be avoided.

Of course, the electronic device disclosed in the embodiment of the present application may also solve the problem of poking injury that may be generated by the sliding of the thimble 700 in other ways. In another alternative, a surface of the first end of the shift lever 530 facing the thimble hole may be provided with an anti-slip structure, and in particular, the anti-slip structure may be a frosted surface or an anti-slip texture. In this case, the anti-slip structure can increase the friction coefficient between the shift lever 530 and the end of the thimble 700, and reduce the probability of the end of the thimble 700 sliding.

In order to improve strength, the first cover 510 and the second cover 520 may be both metal structures in a general case, for example, the first cover 510 and the second cover 520 are both stainless steel structures. The first cover 510 and the second cover 520 may be fixedly coupled by welding. In order to improve the assembly quality of the first cover 510 and the second cover 520, in an alternative scheme, the first cover 510 may be provided with a first positioning hole 511, the second cover 520 may be provided with a second positioning hole 521, and projections of the first positioning hole 511 and the second positioning hole 521 in the butting direction of the first cover 510 and the second cover 520 coincide. In a specific assembling process, an operator may insert a positioning pin into the first positioning hole 511 and the second positioning hole 521 to achieve the matching positioning of the first cover 510 and the second cover 520, and then perform a subsequent assembling operation (e.g., a welding operation). This undoubtedly enables convenient assembly and handling by the operator.

As described above, the shift lever 530 is rotatably disposed in the second installation space, and specifically, a rotating shaft is disposed in the second installation space, a first end of the rotating shaft is fixed to the first cover 510, a second end of the rotating shaft is fixed to the second cover 520, and the shift lever 530 is rotatably engaged with the rotating shaft. In this case, two ends of the rotating shaft rotatably engaged with the shift lever 530 are respectively fixedly connected to the first cover 510 and the second cover 520, so that the rotating shaft can be more stably installed, and the rotating shaft can also play a role of reinforcing the connection between the first cover 510 and the second cover 520.

The rotating shaft may be of various types, for example, the rotating shaft may be an optical shaft, and two ends of the optical shaft may be welded to the first cover 510 and the second cover 520, respectively, so as to achieve the fixed connection between the rotating shaft and the first cover 510 and the second cover 520. In an alternative embodiment, the hinge may be a rivet 550, and the rivet 550 is fixedly connected to both the first cover 510 and the second cover 520. Specifically, at least one end of the rivet 550 may be riveted to the first cover 510 or the second cover 520. The rivet 550 can achieve riveting, which has an advantage of simple operation.

The embodiment of the application discloses a rivet 550 with a specific structure, the disclosed rivet 550 can comprise a rotating connecting part 551 and a bending connecting part 552, the bending connecting part 552 is fixedly connected with the first end of the rotating connecting part 551, and particularly, the bending connecting part 552 and the rotating connecting part 551 can be of an integral structure. The second cover 520 may have a connection hole 522, the bent connection portion 552 passes through the connection hole 522, and is bent to the other side of the second cover 520 away from the first cover 510, and contacts with the surface of the other side of the second cover 520, a clamping mechanism may be formed between the bent connection portion 552 and the end surface 551a opposite to the rotation connection portion 551, the clamping mechanism is clamped and matched with the second cover 520, and the rotation connection portion 551 is rotatably connected with the shift lever 530. The second end of the rotation connection portion 551 and the first cover 510 may be fixedly connected by welding. Of course, the second end of the rotating connection portion 551 may also be provided with a bent connection portion 552, and then another clamping mechanism is formed by the bent connection portion 552 and the end surface of the second end on the rotating connection portion 551, so as to clamp the first cover 510.

For convenience of assembly, in an alternative scheme, the rivet 550 may further include a limit flange 553, the limit flange 553 is fixed to the second end of the rotation connecting portion 551, the shift lever 530 is provided with a stepped hole, the limit flange 553 is in limit fit with the stepped hole, and the limit flange 553 and the first cover 510 may be connected by welding. Of course, the second end of the rivet 550, where the stop flange 553 is located, may be welded to the first cover 510. During the assembling process, an operator can insert the rivet 550 into the stepped hole, and the limit flange 553 of the rivet 550 can be in limit fit with the stepped hole, so that the rivet 550 can be better installed into the stepped hole, thereby achieving the pre-assembly of the rivet 550, then bend the bent connecting part 552, finally weld the first cover body 510 and the second end of the rivet 550, and finally achieve the fixed assembly of the rivet 550.

In the embodiment of the present application, the first cover 510 and the second cover 520 may be an integral structure. For example, the first cover 510 and the second cover 520 may be an integral bent structure, and in particular, the first cover 510 and the second cover 520 may be formed by bending a plate. After the first cover 510 and the second cover 520 are connected, the bent structure of the two covers may form a second installation space.

In an alternative scheme, the first cover 510 may include a first bending portion 512, the first bending portion 512 is bent toward the second cover 520, the first bending portion 512 is welded to the second cover 520, and the first bending portion 512 may be disposed opposite to the rotation axis. In this case, the first bent portion 512 is opposite to the rotating shaft after being welded to the second cover 520, so that the rotating shaft can be protected, the connection strength of the first cover 510 and the second cover 520 at the rotating shaft can be improved, and the deformation of the first cover 510 and the second cover 520 can be reduced.

The shift lever 530 is rotatably engaged with the rotating shaft, and specifically, the shift lever 530 may have a shaft hole 532, and the shaft hole 532 may be a stepped hole as described above or a normal constant-diameter hole. The shaft hole 532 is rotationally matched with the rotating shaft. The shift lever 530 may include a lever top surface facing the first cover 510 and a lever bottom surface facing the second cover 520, the lever top surface and the lever bottom surface being opposite to each other, and the lever top surface and the lever bottom surface may be perpendicular to an axis of the rotation shaft.

In a further technical solution, at least one of the top surface and the bottom surface of the shift lever may include an annular plane 533 surrounding the axial hole 532, and specifically, both the top surface and the bottom surface of the shift lever may include an annular plane 533 surrounding the axial hole 532, and both the first cover 510 and the second cover 520 are slidably attached to the opposite annular plane 533. In this case, during the rotation of the shift lever 530, the first cover 510 and the second cover 520 can both be attached to the opposite annular plane 533 and slide relatively, so as to better limit the shift lever 530 and prevent the shift lever 530 from tilting at a small angle or deforming in a tilting direction under the pushing of the thimble 700.

In an alternative arrangement, the shift lever 530 is provided with a shaft hole 532, and a projection of the shift lever in an axial direction perpendicular to the shaft hole 532 may be located within a projection of the second cover 520 in the axial direction. In this case, the portion of the shift lever 530 where the shaft hole 532 is formed can be supported more stably by the second cover 520, so as to avoid the portion being suspended locally, and further to alleviate the phenomenon that the shift lever 530 is tilted or deformed toward the tilted direction under the pushing of the thimble 700.

Of course, the tilting of the shift lever 530 can be relieved by other methods, and in an alternative embodiment, the first cover 510 has a first limiting area 513, and the rotating shaft is disposed between the first limiting area 513 and the second cover 520. The rotating shaft is connected with the first limiting area 513 in a welding mode, and the first limiting area 513 is in limiting contact with the shifting rod 530 in the axial direction of the rotating shaft. In this case, since the first limiting region 513 is connected to the rotating shaft, the first limiting region has a better strength, so as to perform a better limiting function on the shift lever 530, and also alleviate the phenomenon that the shift lever 530 tips or deforms toward the tip direction under the pushing of the thimble 700.

In order to better limit the shift lever 530 and make it rotate more stably, in a further embodiment, a portion of the first limiting region 513 is bent toward the second cover 520 and is bent to one side of the rotation axis. The bent portion of the first limiting region 513 is in limit fit with the shift lever 530 in the lateral direction of the rotation shaft. It should be noted that the bent portion of the first limiting region 513 is located at one side of the axis of the rotating shaft, and therefore can be in limiting fit with the shift lever 530 at the lateral side of the rotating shaft.

Of course, the shift lever 530 can also be adjusted to achieve the purpose of preventing tipping. In an alternative embodiment, the second end of the shift lever 530 is provided with an anti-tipping limit stage 534 facing the first cover 510, the anti-tipping limit stage 534 is attached to the first cover 510, and the anti-tipping limit stage 534 is in sliding fit with the first cover 510 in the rotation direction of the shift lever 530. In this case, the anti-tipping limit platform 534 is attached to the first cover 510 without affecting the rotation of the shift lever 530, and then can be limited by the first cover 510, so as to prevent the shift lever 530 from tipping.

In a further embodiment, the edge of the anti-tip-limiting platform 534 may be provided with a thickened protrusion 535, the second end of the shift lever 530 may include a lever force-applying surface 536 that can contact with the force-receiving portion 420, and the lever force-applying surface 536 may include a first side surface of the thickened protrusion 535 and a second side surface of the anti-tip-limiting platform 534, where the first side surface is a surface of the thickened protrusion 535 facing the extending direction of the card holder 400, and the second side surface is a surface of the anti-tip-limiting platform 534 facing the extending direction of the card holder 400. The thickened protrusion 535 enables the size of the driving lever force-applying surface 536 of the second end of the driving lever 530 contacting the force-receiving portion 420 to be larger in the axial direction of the rotating shaft, so that the contacting stability of the driving lever 530 and the force-receiving portion 420 can be improved, the phenomenon of dislocation of the force-receiving portion 420 and the driving lever force-applying surface 536 due to deformation can be avoided, and the driving stability of the card holder 400 can be better ensured.

Specifically, the thickened protrusion 535 may further include a third side surface, the third side surface is disposed opposite to the second side surface, and the third side surface is in limit fit with the edge of the first cover 510 in the rotation direction of the shift lever 530, so that the second end of the shift lever 530 is prevented from being excessively retracted into the second installation space.

In the embodiment of the present application, the driving lever applying surface 536 is an acting surface of the driving lever 530 for applying an acting force to the force-receiving portion 420, and the shape of the driving lever applying surface 536 may be various as long as it is ensured that the driving lever 530 applies an acting force to the force-receiving portion 420, so that the card holder 400 extends out of the housing 600. In an alternative embodiment, lever force application surface 536 includes a planar segment 536a and a beveled segment 536b extending obliquely relative to planar segment 536a, planar segment 536a is perpendicular to the direction of penetration of the bore, a first end of beveled segment 536b is connected to planar segment 536a, a second end of beveled segment 536b extends obliquely away from the bore and away from the first end of lever 530, and beveled segment 536b is located on a side of planar segment 536a facing away from the center of rotation of lever 530, i.e., beveled segment 536b is located further away from the center of rotation.

During the rotation of the lever 530, the lever force-applying surface 536 drives the card holder 400 to move through the force-receiving portion 420, and as the rotation of the lever 530 proceeds, the force-receiving portion 420 may first contact the flat section 536a, and then as the rotation of the lever 530 continues and the card holder 400 extends, the lever 530 gradually transitions from the flat section 536a to the inclined section 536b to contact the card holder 400.

As shown in fig. 29 and 30, the urging force of the thimble 700 is set to N1, the ejecting force of the card holder 400 is set to N2, the power arm corresponding to the thimble 700 is L1, the resistance arm of the shift lever 530 is L2, and it is known from N1 × L1 to N2 × L2 that when N1 and L1 are constant, N2 is larger as L2 is smaller, in other words, the resistance arm L2 is smaller, and the card holder ejecting force N2 is larger.

At the initial stage of ejecting the card holder 400, the catching recess 430 of the card holder 400 is elastically locked by the elastic arm 210. In order to break the constraint of the resilient arm 210, a relatively large initial card-holder ejecting force is required to break the constraint of the resilient arm 210, after the resilient arm 210 is broken, the card holder 400 is no longer subjected to the locking force of the resilient arm 210, and then the resistance of the card holder 400 is momentarily reduced. Therefore, a relatively short resistance arm L2 is required. The flat section 536a is disposed on the side of the shift lever 530 closer to the center of rotation, and is located at a smaller distance from the center of rotation, i.e., the resistance arm L2, than L3. The initial moment of ejection of the card holder 400, since the flat section 536a is closer to the card holder 400, it is the earliest to contact the card holder 400, and therefore, a relatively large ejection force can be generated on the card holder 400; when the card holder 400 is pushed out a certain distance and breaks the limit of the elastic arm 210, the card holder 400 continues to be pushed out, and the contact part of the card holder 400 and the shift lever 530 gradually transits from the flat section 536a to the inclined section 536b and finally reaches the second end of the shift lever 530. As can be seen in fig. 29 and 30, the ramp section 536b corresponds to a longer resistance arm L3, and thereafter, no greater card holder ejection force is required to be applied to the card holder 400 during continued extension of the card holder 400 due to the greater resistance arm L3. It can be seen that the above structure enables a user to easily drive the card holder 400 to break through the limitation of the elastic arm 210 during the process of detaching the card holder 400, so as to more easily detach the card holder 400.

In the electronic device disclosed in the embodiment of the present application, the second end of the shift lever 530 may be disposed adjacent to the top of the first cover 510, and may have an outer edge 530 a. The outer rim 530a may include an outer rim body 530a1 and a thickened protrusion 535 disposed on the outer rim body 530a1, the anti-tipping limit stage 534 may include the outer rim body 530a1, a surface of the outer rim body 530a1 facing the protruding direction of the card holder 400 is the second side, the outer rim body 530a1 has a fourth side 530a2 facing the second cover 520, the second end of the shift lever 530 includes a fifth side 530a3 facing the protruding direction of the card holder 400, and the fourth side 530a2 and the fifth side 530a3 may form a concave surface. This concave surface can play the effect of dodging, and under this condition, hold in the palm 400 in-process of dismantling at the card, at the second end of driving lever 530 near perforation pivoted in-process, the concave surface can dodge the partial structure of casing 600, and then avoids taking place to interfere. A portion of the case 600 corresponding to the concave surface (e.g., a portion corresponding to a broken line frame C in fig. 19) does not need to be cut off, and thus, a decrease in strength of the case 600 can be avoided. Specifically, the fourth side 530a2 and the fifth side 530a3 may be perpendicular.

In a further technical solution, an end surface of the second end of the shift lever 530 has an avoiding recess 537 gradually recessed toward the first end of the shift lever 530 in a direction close to the second cover 520, the housing 600 may include a limiting bone 610, the limiting bone 610 extends into the second mounting space, the avoiding recess 537 is in avoiding fit with the second mounting space, and the limiting bone 610 is in limiting contact with an inner side surface of the second cover 520 facing the first cover 510. In this case, the limit rib 610 can play a role of limiting, so as to prevent the second cover 520 from being deformed due to a large deformation and reduce the deformation of the second cover 520 when the second cover 520 is pressed in the direction of the arrow D.

In the electronic device disclosed in the embodiment of the present application, the second cover 520 may include a cantilevered pre-pressing spring 523, and a bottom surface of the second end of the shift lever 530 is included in a bottom surface of the shift lever 530 facing the second cover 520. The cantilever pre-pressing spring 523 elastically contacts the bottom of the second end of the shift lever 530, so as to provide a certain locking function and prevent the shift lever 530 from rotating freely without being forced. In a further technical solution, the bottom surface of the shift lever may include an inclined guide surface 538, and the inclined guide surface 538 is in guiding fit with the cantilevered pre-pressing spring plate 523 in the extending direction of the retainer 400, so that the first end of the shift lever 530 is pushed by the thimble 700, and the second end of the shift lever 530 is easily guided to a position separated from the cantilevered pre-pressing spring plate 523, thereby achieving unlocking.

In order to prevent the false triggering, in a further technical solution, the cantilevered pre-pressing resilient piece 523 may be a bent resilient piece bent toward the first cover 510, and the first convex hull 523a formed by bending the cantilevered pre-pressing resilient piece 523 and the inclined guide surface are elastically limited in the extending direction of the card holder 400, so as to lock the shift lever 530 to a certain extent better and prevent the second end of the shift lever 530 from rotating toward the direction close to the through hole. For better locking, a portion of the shift lever 530 opposite to the first convex hull 523a is elastically clamped between the first convex hull 523a and the first cover 510, so that locking is achieved by elastic clamping.

Alternatively, a second convex hull 514 may be disposed at a position of the first cover 510 opposite to the first convex hull 523a, and a position of the shift lever 530 opposite to the first convex hull 523a may be elastically clamped between the first convex hull 523a and the second convex hull 514. In this case, the first convex hull 523a and the second convex hull 514 can perform the function of elastically clamping the shift lever 530, and at the same time, the contact area between the first cover 510 and the second cover 520 and the shift lever 530 can be reduced, so as to form a point-surface contact matching manner, thereby reducing respective wear during the rotation of the shift lever 530.

Of course, the above-mentioned operation can be achieved in other ways, and specifically, at least one of the surface of the shift lever 530 facing the first cover 510 and the bottom surface of the shift lever 530 facing the second cover 520 may be provided with a third convex hull 539, and the third convex hull 539 is slidably engaged with the inner side surface of the first cover 510 or the second cover 520. In this case, the vertex of the third convex hull 539 forms a point-surface contact with the first cover 510 or the second cover 520, thereby reducing the wear of the shift lever 530 during rotation.

The number of the third convex hulls 539 may be one or more. In an optional scheme, the number of the third convex hulls 539 is at least two, the surface of the shifting lever 530 facing the first cover 510 is a shifting lever top surface, and the regions of the shifting lever top surface located on the two sides of the rotation axis of the shifting lever 530 are all provided with the third convex hulls 539, under the circumstance, the regions of the shifting lever top surface located on the two sides of the rotation axis of the shifting lever 530 can all form point-surface contact with the first cover 510, so that the regions located on the two sides of the rotation axis can all contact with the first cover 510 in the process of rotating the shifting lever 530, the rotating stability of the shifting lever 530 can be improved, and meanwhile, excessive abrasion of the first cover 510 and the shifting lever 530 is avoided.

Similarly, the areas of the bottom surface of the shift lever on both sides of the rotation axis of the shift lever 530 may be provided with third convex hulls 539, and under such a condition, the areas of the bottom surface of the shift lever on both sides of the rotation axis of the shift lever 530 may form point-surface contact with the second cover 520, so that the shift lever 530 may contact with the second cover 520 in the rotation process, the areas on both sides of the rotation axis may contact with the second cover 520, and the rotation stability of the shift lever 530 may be improved, and meanwhile, the second cover 520 and the shift lever 530 may not be excessively worn.

In the electronic device disclosed in the embodiment of the present application, the first cover 510 or the second cover 520 may be provided with a balance arm 515, one end of the balance arm 515 is connected to a side of the first cover 510 or the second cover 520 away from the force applying portion 410 or the force receiving portion 420, the other end of the balance arm 515 extends in a direction away from the first cover 510 or the second cover 520, and the balance arm 515 may be fixedly connected to the circuit board 100. The balance arm 515 can play a balance role, so that the gravity center of the detection ejection mechanism 500 is centered, the problem that the detection ejection mechanism 500 is tilted along the arrow B direction when being assembled on the circuit board 100 by a chip mounting process due to the fact that the detection ejection mechanism 500 is unbalanced is avoided, and the problem that the success rate of chip mounting is low can be solved. Alternatively, the balance arm 515 may be a unitary structure with the first cover 510 or the second cover 520.

The detecting unit 540 is a detecting part for detecting the ejection mechanism 500, and the detecting unit 540 can detect the state of the card holder 400 during a specific operation. In an optional scheme, the detecting portion 540 includes a detecting elastic sheet 541 and a detecting terminal 542, one end of the detecting elastic sheet 541 is connected to the first cover 510 or the second cover 520, the other end of the detecting elastic sheet 541 is an electrical connection end, the detecting terminal 542 is disposed on the first cover 510 or the second cover 520, and when the card holder 400 is in an assembled state, the force applying portion 410 contacts the detecting elastic sheet 541 and drives the electrical connection end to be separated from the detecting terminal 542; when the card holder 400 is in the detached state, the urging portion 410 is separated from the electrical connection terminal, and the electrical connection terminal is electrically contacted to the detection terminal 542. Specifically, the attachment state of the card holder 400 can be determined by detecting the on/off of a circuit between the electrical connection terminal and the detection terminal 542.

In a specific embodiment, the first cover 510 or the second cover 520 may be integrated with the detecting spring 541. The detecting spring 541 may be a grounding spring. In this case, the detection terminal 542 may be connected to a signal source, when the detection terminal 542 is in contact with the electrical connection end, the signal of the detection terminal 542 is grounded through the detection elastic sheet 541, and the electronic device can detect that the detection terminal 542 is at a low level signal. In a specific detection process, the electronic device may determine the state of the card holder 400 by acquiring whether the level signal of the detection terminal 542 is a high level signal or a low level signal.

It should be noted that, herein, the low level signal and the high level signal are relative concepts, and the embodiments of the present application do not limit specific values of the low level signal and the high level signal.

In a specific installation process, the top surface of the elastic sheet 541 facing the first cover 510 may have a fourth convex hull 541c, and the fourth convex hull 541c is in sliding contact with the inner side surface of the first cover 510, under such a condition, the fourth convex hull 541c can realize the sliding contact between the elastic sheet 541 and the first cover 510, so as to improve the stability of deformation of the detection elastic sheet 541, and meanwhile, the convex hull vertex of the fourth convex hull 541c may form point-surface contact with the first cover 510, so as to finally alleviate abrasion between the detection elastic sheet 541 and the first cover 510.

As described above, the detecting elastic piece 541 has an elastic piece top surface facing the first cover 510, and the elastic piece top surface is located between the first cover 510 and the second cover 520, that is, the elastic piece top surface does not protrude from the outer side surface of the first cover 510 or the second cover 520 facing away from the second installation space. In this case, the first cover 510 and the second cover 520 block each other, so that the detecting spring 541 is less likely to be triggered by mistake.

In a further aspect, the electrical connection terminal may include a tip portion 541a1, the tip portion 541a1 being in electrical contact with the detection terminal 542. Since the tip portion 541a1 has a smaller area, it can be more stably contacted with the detection terminal 542 under the driving of the elastic force of the detection elastic piece 541. Meanwhile, the tip portion 541a1 and the detection terminal 542 form a point contact, and in the case where the detection terminal 542 has a stain or an oxide layer, the tip portion 541a1 can provide a larger contact force per unit area than a line contact or a surface contact, and thus can better pierce the stain or the oxide layer, resulting in a good electrical conduction result. The tip portion 541a1 may be included in an overlapping portion 541a described later.

After the assembly is completed, in order to better observe the assembly effect of the detection terminal 542 and the electrical connection end, in an optional scheme, an observation hole 525 may be formed in a portion of the first cover 510 or the second cover 520 opposite to the electrical connection end, so as to facilitate the inspection of an operator.

In general, the first cover 510 and the second cover 520 are metal members having high strength in order to improve the strength of the detection ejection mechanism 500 and facilitate the discharge of static electricity. In order to avoid the erroneous contact between the detection terminal 542 and the first cover 510 or the second cover 520, an optional scheme may be that an insulating portion 560 is disposed in the second installation space, the detection terminal 542 is fixed on the insulating portion 560, and the detection terminal 542 may be connected to the first cover 510 or the second cover 520 through the insulating portion 560 in an insulating manner. In this case, the insulating portion 560 can function as a good insulating spacer.

Specifically, the insulating portion 560 may be filled with glue, or may have another structure, and in an alternative scheme, the insulating portion 560 may be an injection molded structural member, and the detection terminal 542 and the insulating portion 560 are connected by injection molding. In this case, the insulating portion 560 not only functions as insulation and isolation, but also functions to fix the detection terminal 542.

In order to further improve the mounting firmness of the insulating portion 560, optionally, the first cover 510 or the second cover 520 may have a first position-limiting portion 516, the first position-limiting portion 516 extends into the second mounting space, and the first position-limiting portion 516 and the insulating portion 560 are in position-limiting fit in the first direction, so that the insulating portion 560 can be prevented from moving relative to the first cover 510 or the second cover 520.

Further, the first cover 510 or the second cover 520 may have a second limiting portion 517, the second limiting portion 517 extends into the second mounting space, the second limiting portion 517 and the insulating portion 560 are in limiting cooperation in a second direction, and the second direction is intersected with the first direction. In this case, the first stopper portion 516 and the second stopper portion 517 can restrict the insulating portion 560 in two intersecting directions, and the firmness of the insulating portion 560 can be improved. Specifically, the first direction and the second direction may be perpendicular. Both the first stopper portion 516 and the second stopper portion 517 may be formed by bending.

In this application embodiment, the electric connection end can include overlap joint section 541a and the section 541b of bending, overlap joint section 541a links to each other with the section 541b of bending, the section 541b of bending is sunken towards the direction of application of force portion 410, and the section 541b of bending bends the arch that forms and sets up with application of force portion 410 relatively, the section 541b of bending and the spacing cooperation of detection terminal 542 in the sunken direction of the section 541b of bending, in the installation of card support 400, application of force portion 410 carries out the application of force to detection shell fragment 541 through the arch of the section 541b of bending. In the process of detaching the card holder 400, the force application portion 410 is separated from the protrusion formed by the bending section 541b, and the lap section 541a is in limit fit with the detection terminal 542 under the elastic recovery of the detection elastic sheet 541, so that normal fit is ensured.

In a further embodiment, the bending section 541b may include a widened portion 541b1, and the widened portion 541b1 may enable the width of the bending section 541b to be larger, so as to be able to cooperate with the force application portion 410 in a larger area, thereby improving the stability of contact.

In an alternative scheme, the first cover 510 may include a first blocking portion 518, a hollowed area 519 is disposed on one side of the first blocking portion 518, the hollowed area 519 is opposite to the bending section 541b, a distance between the first blocking portion 518 and the through hole is a first distance, a distance between the bending section 541b and the through hole is a second distance, and the first distance is smaller than the second distance. In this case, the first blocking portion 518 is closer to the through hole, and during the intrusion of the foreign object, the foreign object will first contact the first blocking portion 518, thereby preventing the foreign object from further stabbing the detection spring 541.

In a further technical solution, the second cover 520 has a second bending portion 524, the second bending portion 524 bends toward the first cover 510, and the second bending portion 524 is welded to the second cover 520, so that the connection area between the first cover 510 and the second cover 520 is further increased, which is beneficial to improving the connection firmness.

The first cover 510 may include a third bent portion 5110, the third bent portion 5110 is bent toward the second cover 520, and the third bent portion 5110 is welded to the second cover 520. This can further improve the stability of the connection of the first cover 510 and the second cover 520.

In a further technical solution, the first cover 510 may further include a first outer extension 5111 extending from the third bending portion 5110 to a side of the third bending portion 5110, and the third bending portion 5110 and the first outer extension 5111 form a second barrier for covering a surface of the insulating portion 560 facing the through hole. In this case, since the second stopper can cover the insulating portion 560, the insulating portion 560 can be protected, and the insulating portion 560 can be prevented from being damaged when foreign matter enters.
