Technical Field

The application relates to the technical field of electronic equipment, in particular to mounting equipment for a support, electronic equipment and a pre-tightening piece.

Background

In the process of research, development, manufacture, use and the like of electronic equipment, the stress strength and reliability of some structural components are always important consideration factors. Taking a mobile phone as an example, some mobile phones are usually provided with a middle frame and other structural members, and components such as a display screen, a circuit board or a shell can be fixedly installed on the middle frame so as to be assembled into a whole. In practical application, factors such as installation positions of components and space avoidance are considered, the structure of the middle frame is generally complex, and the stress performance of some areas is poor. When subjected to a large external force or repeated stress, the sheet is likely to have defects such as cracks or fractures. Therefore, how to improve the stress performance of the structural members such as the middle frame and the like is a technical problem to be solved in the field.

Disclosure of Invention

The application provides a support, electronic equipment and mounting apparatus of pretensioning piece that atress performance is good and be convenient for make.

In one aspect, the present application provides a stent including a stent body and a preload member. The support body is provided with a part to be reinforced, and the pre-tightening piece is arranged on at least part of the periphery of the part to be reinforced and used for pre-tightening the support of the part to be reinforced. Wherein, the periphery of the portion to be reinforced refers to the outer surface of the portion to be reinforced, or the vicinity of the portion to be reinforced. The pretension piece is used for exerting pretension force to the part to be reinforced so as to improve the stress performance of the part to be reinforced. Wherein, the stress performance includes but is not limited to stress strength and fatigue resistance. When the support receives external force impact, alternative tensile or compressive load, the atress intensity and the fatigue resistance of this portion of waiting to strengthen can be promoted to the pretension piece. In addition, when the concrete implementation is carried out, the arrangement position of the pre-tightening piece also has higher flexibility and convenience, so that the flexible reinforcement can be carried out aiming at different areas, and the implementation difficulty is lower.

In practical application, the structural shape, material and manufacturing process of the stent body are not limited. That is, the preload members may be applied to stent bodies of many different shapes and types to reinforce areas of the stent body where reinforcement is desired.

The number, position, structural shape and other parameters of the parts to be reinforced can be various.

For example, the portion to be reinforced may be a neck structure. Specifically, the cross-sectional area of the portion to be reinforced may be smaller than the cross-sectional area of the adjacent region. Therefore, the force-receiving performance of the partial region is inferior to that of the adjacent region. When the support is subjected to external force, the to-be-reinforced part is easy to bend, crack, break and other adverse conditions. Therefore, the part to be reinforced can be reinforced through the pre-tightening piece, so that the stress performance of the part to be reinforced is improved.

Alternatively, the portion to be reinforced may be a slit or a notch. For example, a gap may be provided between the first region and the second region of the stent body. When the support suffers from external force, the seam department produces unfavorable condition such as deformation, fracture easily, consequently, can tighten (or tie) first region and second region through the pretension piece to the condition such as deformation, fracture appear in the seam department.

In addition, when the concrete implementation, the shape structure of support body may be more complicated, leads to treating to set up the pretensioning piece on some hardly, consequently, can set up corresponding structure on the support body and promote the convenience of setting up of pretensioning piece.

For example, threading holes may be provided at (or elsewhere near) the portion to be reinforced. When the pretensioning piece is arranged, the pretensioning piece can penetrate through the threading hole and then pretension the part to be strengthened.

In other embodiments, after the pretension piece passed through the through wires hole, also can pack the reinforcement medium in the through wires hole to promote the structural strength of through wires hole department, in addition, can also guarantee the stability between pretension piece and the support body, prevent the condition such as slippage, rocking.

In addition, the type of configuration of the preload member may vary depending on the particular application.

For example, the preload member may be a wire body. When setting up, the preload piece of line body structure can twine the at least partial periphery of portion of waiting to strengthen to for waiting to strengthen provides the pretightning force. The wire body can be in a closed loop structure or an open loop structure. For example, the preload member may be an open loop structure such as a straight line, a curved line, a spiral line, or the like. Or a closed loop structure such as a single-turn or multi-turn coil.

When the preload part is in an open-loop wire body structure, two ends of the wire body can be fixedly connected with the bracket body (or the part to be reinforced).

In addition, the preload member may be of a plate structure. When the plate body structure is arranged, the pre-tightening piece of the plate body structure can be wrapped on at least part of the periphery of the part to be strengthened, so that pre-tightening force is provided for the part to be strengthened. The plate body can be in a closed-loop structure or an open-loop structure. For example, the preload member may be an open loop structure such as a length of straight plate or a curved plate. Or may be a closed loop structure that encloses a cylindrical or other shape.

When the preload member is in an open-loop plate structure, at least part of the edge of the plate body can be fixedly connected with the bracket body (or the part to be reinforced).

In addition, in order to enable the plate body to provide effective pretightening force for the portion to be reinforced, when the plate body is implemented, the inner plate surface (the plate surface facing the portion to be reinforced) of the plate body can be tightly attached to the outer surface of the portion to be reinforced.

Wherein, the material of pretensioning piece can be aluminum alloy, steel, carbon fiber, nylon etc. Alternatively, it is also understood that the pretensioning member can be a structural member having a higher flexibility or a higher rigidity. The material and structural properties of the preload members are not limiting in this application.

On the other hand, this application still provides an electronic equipment, including functional component and support body, functional component can fix on the support body to the group can assemble into an overall structure. Wherein, the functional component can include: display screen, circuit board assembly, casing, etc. For example, the display screen may be fixedly mounted on one side of the stand body, and the circuit board assembly may be fixedly mounted on the other side of the stand body. The rear cover can be covered on the outer side of the circuit board assembly and is fixedly connected with the support body, so that the circuit board assembly can be well protected. The support can be used as a stress main body of the mobile phone, when the mobile phone is dropped, pressed, bent and the like, the support can keep the overall shape of the mobile phone through the structural strength of the support, and the situations of disassembly, breakage, bending and the like of the mobile phone are prevented.

In a specific implementation, the electronic device may be a mobile phone, a tablet computer, a notebook computer, or the like, and the type of the electronic device is not limited in this application.

On the other hand, the application also provides a mounting device of the preload piece, which is used for mounting the preload piece on the part to be reinforced of the bracket body. Wherein the mounting device may comprise a clamping arm for winding the pre-load member of the open-loop configuration around at least part of the periphery of the portion to be reinforced. The pre-tightening piece of the open-loop structure can be a line body structure or a plate body structure.

Wherein, the setting quantity and the motion mode of arm lock do not do the restriction in this application.

Alternatively, the mounting apparatus may further comprise a plurality of support posts. Wherein the plurality of support columns may form a shaped outline (e.g., a quadrilateral). The pretensioning piece (such as a closed-loop coil) of the closed-loop structure can be sleeved on the plurality of supporting columns to form the outline (such as a quadrangle), so that the pretensioning piece can be sleeved on the periphery of the part to be reinforced conveniently.

Detailed Description

In order to facilitate understanding of the technical solution of the present application, an application scenario thereof is first described below.

The support provided by the embodiment of the application can be applied to various types of electronic equipment such as mobile phones, tablet computers and notebook computers. Some components of the electronic device may be fixed to the stand so as to be assembled into one body. Wherein, the support not only can provide the mounted position for this subassembly, can also provide certain atress performance for electronic equipment is when suffering external force, is difficult for producing unfavorable condition such as deformation.

As shown in fig. 1, a mobile phone is taken as an example. The mobile phone may include: display screen 10, circuit board assembly 20, back cover 30, and bracket 40 (also understood to be a center frame). The display screen 10 may be fixedly mounted on one side (upper side in the drawing) of the bracket 40, and the circuit board assembly 20 may be fixedly mounted on the other side (lower side in the drawing) of the bracket 40. The rear cover 30 can cover the lower side of the circuit board assembly 20 and is fixedly connected with the bracket 40, so that the circuit board assembly 20 can be well protected. The support 40 can be used as a stressed main body of the mobile phone, and when the mobile phone is dropped, pressed, bent and the like, the support 40 can keep the overall shape of the mobile phone through the structural strength of the support, so that the mobile phone is prevented from being disassembled, broken, bent and the like. In general, the material and dimensions of the frame 40 may be selected to provide a corresponding design for increasing the structural strength of the frame 40. For example, the bracket 40 may be made of a material with high strength to improve the stress performance of the bracket 40. Alternatively, the force-bearing capacity of the bracket 40 may be increased by increasing its size (e.g., thickness). However, in general, the material with higher strength generally has higher density, which significantly increases the weight of the holder 40, and thus is not favorable for realizing a lightweight design of the mobile phone. In addition, when the size of the support 40 is increased, the whole mobile phone becomes thicker and heavier, and the space occupation in the whole mobile phone is increased significantly, thereby affecting the arrangement of other components (such as a circuit board assembly). On the other hand, the mobile phone has more components and is more complicated in arrangement position. Therefore, in practical applications, the structural shape of the stent 40 is often complicated, resulting in poor stress performance at some locations in the stent 40. However, at present, there is no structural design for effectively reinforcing a specific part, so that the stress performance of the bracket 40 cannot be effectively improved.

Therefore, the support which is good in stress performance, beneficial to achieving light-weight design and convenient to manufacture is provided in the embodiment of the application.

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and specific embodiments.

The terminology used in the following examples is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, such as "one or more", unless the context clearly indicates otherwise. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" means one, two or more. The term "and/or" is used to describe an association relationship that associates objects, meaning that three relationships may exist; for example, a and/or B, may represent: a alone, both A and B, and B alone, where A, B may be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

In order to facilitate understanding of the technical solution of the present application, the following description will specifically describe the support as a middle frame of the mobile phone. It is understood that, in the implementation, the bracket may also be a structural member of other types of electronic devices (such as a tablet computer, a notebook computer, etc.), and the structural shape of the bracket is not limited in this application.

As shown in FIG. 2, in the embodiment provided herein, the stent 40 comprises a stent body 41 and a plurality of pretensioning members. Wherein the preload member 42a is provided on the outer surface of the first portion to be reinforced 411 a; the preload member 42b is provided on the outer surface of the second portion to be reinforced 411 b; the preload member 42c is provided on the outer surface of the third portion to be reinforced 411 c. Namely, each pre-tightening piece is used for applying pre-tightening force to the corresponding part to be strengthened so as to improve the stress performance of the part to be strengthened. Wherein, the stress performance includes but is not limited to stress strength and fatigue resistance. In the support that this application embodiment provided, can apply the pretightning force to the portion of waiting to strengthen of support body 41 through the preload piece, realize the preload to promote the atress performance of support body 41 (or wait to strengthen). When the bracket 40 is subjected to external impact, alternate tensile or compressive load, the preload piece can improve the stress strength and fatigue resistance of the part to be reinforced. In addition, when the concrete implementation is carried out, the arrangement position of the pre-tightening piece also has higher flexibility and convenience, so that the flexible reinforcement can be carried out aiming at different areas, and the implementation difficulty is lower.

In practical applications, the structural shape, material and manufacturing process of the bracket body 41 are not limited. That is, the preload member can be applied to the stent body 41 in various shapes and types to reinforce a portion (or area) of the stent body 41 where reinforcement is required.

For example, as shown in fig. 2. In the embodiment provided in the present application, the holder body 41 is a middle frame of a mobile phone. Specifically, the holder body 41 is a substantially rectangular frame-shaped structure. In specific implementation, the holder body 41 may be made of a metal material or a non-metal material such as stainless steel or aluminum alloy. In terms of manufacturing process, the stent body 41 can be manufactured by die casting, CNC (Computer numerical control) processing, and the like.

In practical applications, the number, position, structural shape and other parameters of the portions to be reinforced can be varied.

As shown in fig. 2, in the embodiment provided by the present application, three portions to be reinforced are shown, a first portion to be reinforced 411a, a second portion to be reinforced 411b, and a third portion to be reinforced 411 c.

The first portion to be reinforced 411a is a neck structure. Specifically, the cross-sectional area of the first portion to be reinforced 411a is smaller than that of the adjacent region. Therefore, the force-receiving performance of the partial region is inferior to that of the adjacent region. When the bracket 40 is subjected to an external force, the first portion to be reinforced 411a may be more likely to be bent, cracked, broken, or the like. Therefore, the first portion to be reinforced 411a can be reinforced by the preload member 42a to improve the force-receiving performance of the first portion to be reinforced 411 a.

As shown in fig. 3, the second portion to be reinforced 411b is located at the interface of the bracket body 41. Specifically, a through hole 43 is formed in the partial region, and an interface (such as micro usb, type-c, lighting, etc.) of the mobile phone can be connected to an external device such as a data line through the through hole 43. In the partial area, the through hole 43 is opened, so that the force-bearing performance of the partial area is reduced. In addition, in the use process, the interface can be frequently plugged and pulled, and the like, so that the failure risk of the partial area can be further aggravated. Therefore, the second portion to be reinforced 411b can be structurally reinforced by the preload member 42b to improve the force-receiving performance in this area.

As shown in fig. 4, the third portion to be reinforced 411c is located at the slot 44 of the antenna. Specifically, there is a gap 44 between the first region 401 and the second region 402. The first region 401 or the second region 402 can be used as an emitter or a receiver of the antenna signal of the mobile phone. Alternatively, an antenna located inside the mobile phone may transmit or receive an electromagnetic signal to or from the outside through the slot 44. When the bracket 40 is subjected to an external force, the gap 44 is prone to deformation, cracking and other undesirable conditions, and therefore, the first region 401 and the second region 402 can be tightened (or bound) by the pre-tightening piece 42c to prevent the gap 44 from deformation, cracking and other conditions.

The type of construction of the preload members may vary depending on the particular application. To facilitate understanding of the specific structure and arrangement of the preload member, first, a detailed description will be given taking an example in which the preload member 42a is provided in the first portion to be reinforced 411 a.

As shown in FIG. 5, in one embodiment provided herein, the preload members 42a are closed loop coils (9 are shown). Specifically, each closed-loop coil is of a single-loop structure, and the closed-loop coil is sleeved on the periphery of the first portion to be reinforced 411a in a tightening state, so that a pre-tightening force can be provided for the first portion to be reinforced 411a, and the stress performance of the first portion to be reinforced 411a is improved. When the first portion to be reinforced 411a is subjected to an external force, on one hand, under the action of a pre-tightening force, the structural strength of the first portion to be reinforced 411a is strengthened to a certain extent, and therefore, the stress performance of the first portion to be reinforced 411a itself is obviously improved. On the other hand, the closed-loop coil can also effectively absorb and buffer external force, and therefore, external force received by the first portion to be reinforced 411a can also be further reduced.

In practical implementation, the outer periphery of the first portion to be reinforced 411a is not limited to the nine closed-loop coils, and may include fewer or more than nine closed-loop coils. In addition, the plurality of closed-loop coils may be disposed at equal intervals or may not be disposed at equal intervals in the first portion to be reinforced 411 a. The number of the closed-loop coils and the arrangement position of each closed-loop coil can be adjusted adaptively according to actual requirements, and the application does not limit the number of the closed-loop coils and the arrangement position of each closed-loop coil.

In addition, when specifically configured, the closed-loop coil may be formed in a closed-loop structure in advance, and then sleeved on the outer periphery of the first portion to be reinforced 411 a. Alternatively, a segment of a wire may be wound around the outer periphery of the first portion to be reinforced 411a, and then both ends of the segment may be connected to form a closed loop structure. When the connection is performed, the two ends of the line segment may be connected by welding, bonding, clamping, and the like, and the specific connection mode is not limited in this application.

In other embodiments, the preload member 42a may have other wire body configurations.

For example, as shown in FIG. 6, in another embodiment provided herein, the preload member 42a is a helical coil. In practical implementation, a segment of line may be spirally wound around the outer periphery of the first portion to be reinforced 411 a. Alternatively, the preload member 42a may be first formed into a spiral shape, and then the spiral coil may be fitted around the outer periphery of the first portion to be reinforced 411 a. When the first portion to be reinforced 411a is subjected to an external force, on one hand, under the action of a pre-tightening force, the structural strength of the first portion to be reinforced 411a is strengthened to a certain extent, and therefore, the stress performance of the first portion to be reinforced 411a itself is obviously improved. On the other hand, the helical coil can also effectively absorb and buffer the external force, and therefore, the external force applied to the first portion to be reinforced 411a can also be further reduced. For example, when the first portion to be reinforced 411a tends to bend under the action of an external force, the helical coil may absorb and cushion the external force to effectively alleviate the amount of bending deformation of the portion to be reinforced.

In other embodiments, the spiral coil may be wound more closely around the outer periphery of the first portion to be reinforced 411 a. Alternatively, it is also understood that the pitch of the helical coil can be reduced as much as possible.

In practical applications, both ends of the spiral coil may be in a free state (i.e., both ends of the spiral coil are not fixedly connected to any structure). Alternatively, both ends or at least one end of the spiral coil may be fixed to the first portion to be reinforced 411a or other positions than the first portion to be reinforced 411a, so as to prevent the spiral coil from being loosened, and prevent the spiral coil and the first portion to be reinforced 411a from being slipped off. In specific implementation, the two ends of the spiral coil and the first portion to be reinforced 411a or other positions except the first portion to be reinforced 411a may be fixedly connected by welding, bonding, clamping, or the like. The specific connection is not limiting in this application.

In addition, when the first portion to be reinforced 411a is specifically provided, a plurality of spiral coils may be sleeved on the outer circumference of the first portion to be reinforced 411 a.

For example, as shown in fig. 7, in one embodiment provided by the present application, the outer periphery of the first portion to be reinforced 411a is sleeved with two spiral coils, and the two spiral coils are arranged at intervals on the outer periphery of the portion to be reinforced. Specifically, the first spiral coil 421a is sleeved on the left half area of the first portion to be reinforced 411a, and the second spiral coil 422a is sleeved on the right half area of the first portion to be reinforced 411 a. In a specific arrangement, the parameters of the first spiral coil 421a and the parameters of the second spiral coil 422a (such as the pitch, the number of turns, the direction of rotation, etc.) may be the same or different, and are not limited herein.

In the case where a plurality of spiral coils are provided, the plurality of spiral coils may be provided in parallel.

For example, as shown in fig. 8, in another embodiment provided by the present application, a first spiral coil 421a and a second spiral coil 422a are provided around the outer periphery of the first portion to be reinforced 411a in a juxtaposed fashion. In a specific implementation, the magnitudes of the pretightening forces provided by the first spiral coil 421a and the second spiral coil 422a may be the same or different. It will be appreciated that in the above embodiments, only two spiral coils are illustrated by way of example. In a specific implementation, the number of the spiral coils may also be three or more, which is not described herein.

In other embodiments, the preload member 42a may have other configurations.

For example, as shown in FIG. 9, in another embodiment provided herein, the preload member 42a is a line segment. Wherein, both ends of the line segment are fixedly connected with the first portion to be reinforced 411 a. That is, the first portion to be reinforced 411a can be pre-tensioned in the region between the two ends of the line segment.

In a specific application, when the preload member 42a is the above-mentioned wire body structure, the cross-sectional shape of the wire body may be a polygonal structure such as a circle, an ellipse, a rectangle, and a hexagon. The material of the wire body can be aluminum alloy, steel, carbon fiber, nylon and other materials. Alternatively, it is also understood that the preload member 42a may be a wire body having a high flexibility, or a wire body having a high rigidity. In specific implementation, the material of the preload piece 42a can be reasonably selected according to actual requirements, and the application is not limited.

In summary, in practical implementation, when the preload member 42a is a linear body structure, the preload member 42a may be a closed loop structure or an open loop structure.

In addition, in some embodiments, the preload member 42a may be a strap, a plate, or a structural member with other shapes besides the wire body structure.

For example, as shown in fig. 10, in one embodiment provided herein, the preload member 42a is a plate structure. Specifically, the pretensioning members 42a of three plate structures are arranged around the outer peripheral surface of the first portion to be reinforced 411a at intervals, and the inner plate surface (the plate surface facing the first portion to be reinforced 411 a) of the plate body is tightly attached to the outer surface of the first portion to be reinforced 411a, so as to provide a good pretensioning force for the first portion to be reinforced 411 a. In specific implementation, a section of plate body may be selected, and then the plate body is surrounded on the outer circumferential surface of the first portion to be reinforced 411a, and finally, the two ends of the plate body are fixedly butted. Alternatively, in other embodiments, the plate body may be made into a cylindrical structure, and then the fastening member 42a of the cylindrical structure is sleeved on the outer periphery of the first portion to be reinforced 411 a. In order to facilitate the fastening member 42a to be sleeved on the periphery of the first portion to be reinforced 411a, in specific implementation, the fastening member 42a may be made of a material with good elasticity.

In addition, as shown in fig. 11, in another embodiment, the preload member 42a is a plate body, and both left and right ends of the plate body are fixedly connected to the first portion to be reinforced 411 a. That is, the first portion to be reinforced 411a can be pre-tensioned in the area between the two ends of the plate.

In general, in practical implementation, when the preload member 42a is a plate body, the preload member 42a may be a closed loop structure or an open loop structure.

It is to be understood that, in the above embodiment, the specific structure and arrangement of the preload member 42a are exemplified by the first portion to be reinforced 411 a. It is understood that, in the implementation, the preload members 42b and 42c may be configured in the same or similar manner as the preload member 42a, and will not be described herein.

In addition, in practical implementation, the shape and structure of the bracket body 41 may be complex, which makes it difficult to arrange the pre-tightening member on some portions to be reinforced, and therefore, the bracket body 41 may be provided with a corresponding structure to improve the convenience of arrangement of the pre-tightening member.

For example, as shown in fig. 12, in one embodiment provided by the present application, threading holes (four are shown) are provided in the vicinity of the second portion to be reinforced 411 b. When the fastening member 42b is disposed, the fastening member 42b may be passed through the threading hole 45 and then the second portion to be reinforced 411b is pre-tightened. Specifically, the preload member 42b is exemplified as a wire body. When the preload member 42b is disposed, one end of the wire body may be inserted through the threading hole 45, and then the wire body is wound around the outer circumference of the second portion 411b to be reinforced, so as to dispose the preload member 42 b. Finally, the two ends of the wire body may be butted or fixed to the holder body 41, respectively. When the device is specifically set, flexible selection and adjustment can be performed according to actual requirements.

In addition, when the preload pieces 42b are configured as a belt body, a plate body, or the like, the cross section and the installation position of the threading hole 45 can be flexibly adjusted. In the specific arrangement, it is sufficient to ensure that the preload member 42b can pass through smoothly and achieve a good preload on the second portion to be reinforced 411 b.

In other embodiments, after the preload piece 42b passes through the threading hole 45, the threading hole 45 can be filled with a reinforcing medium, so that the structural strength of the threading hole 45 is improved, and in addition, the stability between the preload piece 42b and the bracket body 41 can be ensured, and the situations of slipping, shaking and the like are prevented.

In a specific arrangement, the reinforcing medium may be solder, adhesive, or the like. The specific type and arrangement of the reinforcing media is not limiting in this application.

In addition, in the third portion to be reinforced 411c, a corresponding structure may also be provided to improve the convenience and reliability of the setting of the preload member 42 c.

For example, as shown in fig. 13, a first recess 4011 may be provided in the first region 401, and a second recess 4021 may be provided in the second region 402. The preload member 42c is a closed loop coil. The coil may be nested within the first recess 4011 and the second recess 4021. To bind the first area 401 and the second area 402 so that the first area 401 and the second area 402 tend to approach each other. When the stent body 41 is subjected to an external force, the first region 401 and the second region 402 may tend to move away from each other, resulting in the slit 44 being enlarged. The positional stability between the first region 401 and the second region 402 can be effectively maintained by the preload member 42c, preventing the gap 44 from being enlarged. In specific implementation, the shapes, the arrangement positions, and the number of the first recesses 4011 and the second recesses 4021 may be flexibly arranged, which is not described herein again.

In practical applications, the first region 401 or the second region 402 may be used as a radiator or a receiver of the antenna signal of the mobile phone. Alternatively, an antenna located inside the mobile phone may transmit an electromagnetic signal to the outside through the slot 44, or receive an electromagnetic signal from the outside. The gap 44 may be filled with an insulating medium (such as resin, etc.) to ensure the connection effect between the first region 401 and the second region 402 and the integrity of the stent body 41.

It is to be understood that the shape of each portion to be reinforced is not limited to the shape shown in the above-described embodiments in specific applications. In addition, the shape and arrangement of each preload member are not limited to those shown in the above embodiments. In practical application, the shapes of the parts to be reinforced can be various, and correspondingly, the shapes and the arrangement modes of the pre-tightening pieces can be flexibly arranged and adjusted according to the shapes of the parts to be reinforced. In addition, the shapes and arrangement of the preload members may be the same or different in the plurality of portions to be reinforced. In a single part to be reinforced, only the same type of structure of preload members may be provided, or different types of preload members may be provided.

On the other hand, the embodiment of the application also provides a mounting device of the preload piece, which is used for arranging the preload piece on the bracket body.

As shown in fig. 14, in one embodiment provided herein, the mounting apparatus includes a first clamp arm 51 and a second clamp arm 52. Take the preload member 42 as a linear body structure for example. When the clamp is used, the first clamp arm 51 can clamp one end (lower end in the figure) of the fixed wire body, and the second clamp arm 52 can clamp the other end (upper end in the figure) of the fixed wire body.

Please refer to fig. 15. The second clamping arm 52 is moved and turned over, so that the wire body is wound on the outer circumferential surface of the portion to be reinforced 411. Then, the crossing position of the wire body is cut, and the two ends of the wire body are butted, so that the setting of the preload piece 42 can be realized.

When the installation equipment is specifically implemented, the number of the clamping arms contained in the installation equipment can be correspondingly set according to actual requirements.

For example, as shown in fig. 16 and 17, in another embodiment provided by the present application, three clamp arms are included, namely a first clamp arm 51, a second clamp arm 52 and a third clamp arm 53 (not shown in fig. 16). Both sides of the portion to be reinforced 411 have a first through hole 43a and a second through hole 43 b.

As shown in fig. 16, when the device is installed, the wire may be inserted through the first through hole 43a, the first clip arm 51 may clamp and fix one end (lower end in the drawing) of the wire, and the second clip arm 52 may clamp and fix the other end (upper end in the drawing) of the wire.

Please refer to FIG. 17. The second clamping arm 52 is moved and turned over so that one end of the wire body passes through the second through hole 43 b. When the wire body passes through the through hole 43b, the wire body is clamped and fixed by the third clamping arm 53, and the second clamping arm 52 cancels the clamping of the wire body.

Please refer to fig. 18. At the moment, the second clamping arm completely cancels the clamping and fixing of the wire body. In addition, in order to prevent the second clamping arm from interfering with the position of the line body, the second clamping arm can be moved to other positions.

Please refer to fig. 19. The third clamping arm 53 is moved and turned over, and finally the wire body is wound on the outer circumferential surface of the portion to be reinforced 411. Then, the position where the wire body crosses is cut, so that both ends of the wire body can be butted.

As shown in fig. 20, the two ends of the cut line body can be fixedly connected by welding, bonding, or the like.

It is understood that in other embodiments, the first clamping arm 51 may be movable and reversible. Alternatively, more clamping arms may be provided. When the clamp arm is specifically arranged, the arrangement number and type of the clamp arm are not limited in the application.

In other embodiments, the wire body of the closed-loop structure may also be directly sleeved on the periphery of the portion to be reinforced.

For example, as shown in fig. 21, in another embodiment provided herein, the mounting apparatus includes four support columns, a first support column 54, a second support column 55, a third support column 56, and a fourth support column 57. The portion to be reinforced includes a first region 401 and a second region 402 with a gap 44 between the first region 401 and the second region 402. The preload member 42 is a closed loop coil. When the arrangement is performed, the closed-loop wire can be sleeved on the four supporting columns, and then the four supporting columns are moved to the periphery of the first region 401 and the second region 402.

Please refer to fig. 22. The first 54 and third 56 support posts are retracted so that the upper left corner of the coil overlaps the upper left corner of the first region 401 and the lower right corner of the coil overlaps the lower right corner of the second region 402.

Please refer to fig. 23. The second support column 55 and the fourth support column 57 are retracted so that the upper right corner of the coil overlaps the upper right corner of the second area 402 and the lower left corner of the coil overlaps the lower left corner of the first area 401. Finally, the coil is sleeved on the periphery of the first area 401 and the second area 402, so that pretightening force is provided between the first area 401 and the second area 402. It is understood that in other embodiments, the specific type of installation device and the installation manner of the preload member 42 are not limited in this application, and the installation device can be flexibly adjusted according to actual needs.

On the other hand, as shown in fig. 24, an electronic device is further provided in the embodiments of the present application, and includes a functional assembly and a bracket 40, where the functional assembly may be fixedly mounted on the bracket 40 by clamping, bonding, screwing, and the like, so as to assemble an integral structure. The functional components include, but are not limited to, a circuit board assembly, a housing, a display screen, and the like.

For example, in the case of a cellular phone, the functional components may include a circuit board assembly 20, a display screen 10, and a rear cover 30. The display screen 10 may be fixedly mounted on one side (upper side in the drawing) of the stand body 41, and the circuit board assembly 20 may be fixedly mounted on the other side (lower side in the drawing) of the stand body 41. The rear cover 30 can cover the lower side of the circuit board assembly 20 and is fixedly connected with the bracket body 41, so that the circuit board assembly 20 can be well protected. The support 40 can be used as a stressed main body of the mobile phone, and when the mobile phone is dropped, pressed, bent and the like, the support 40 can keep the overall shape of the mobile phone through the structural strength of the support, so that the mobile phone is prevented from being disassembled, broken, bent and the like.

In a specific implementation, the electronic device is not limited to a mobile phone, but may also be a tablet computer, a notebook computer, or the like. This is not a limitation of the present application.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
