Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1, 2, 3 and 4, a display screen 10 according to an embodiment of the present invention includes a supporting mechanism 20 and a display module 30, where the display module 30 includes a plurality of display units 31 (as shown in fig. 5), the display units 31 have a smaller display area and can display images, and the display modules 30 with a larger display area can be formed by splicing the plurality of display units 31 in a horizontal direction and a vertical direction. Two adjacent display units 31 can be spliced to each other by the fixing lock 32. The display module 30 has a front surface 33 and a back surface 34, the front surface 33 and the back surface 34 are arranged at intervals along the thickness direction of the display module 30 and face opposite to each other, the image displayed by the display module 30 is displayed through the front surface 33, and the support mechanism 20 is arranged on the back surface 34 of the display module 30. When the front surface 33 is a plane 33a, the display module 30 is plane-tiled, i.e. the display module 30 is in a plane-tiled state. When the front surface 33 is a curved surface which is entirely curved toward the supporting mechanism 20, the curved surface is a right curved surface 33b, and the display module 30 is a right arc splicing state, that is, the display module 30 is in a right arc splicing state, it is obvious that the centerline axis surrounded by the right curved surface 33b is located on the side where the back surface 34 is located. When the front surface 33 is a curved surface totally curved away from the supporting mechanism 20, the curved surface is an arc-shaped surface 33c, and the display module 30 is arc-shaped spliced, that is, the display module 30 is in an arc-shaped spliced state, it is obvious that a centerline axis surrounded by the arc-shaped surface 33c is located on one side of the front surface 33. When the front surface 33 is formed by the plane 33a, the front arc surface 33b and the reverse arc surface 33c, the front surface 33 is S-shaped or wave-shaped, that is, the display module 30 is spliced in an S-shaped or wave-shaped manner. The support mechanism 20 includes a support bracket 100, a linkage 200, an adjustment assembly 300, and a mounting lock 400.

Referring to fig. 6, 7, 8 and 11, in some embodiments, the support frame 100 includes two longitudinal beams 130 and two cross beams 140, the longitudinal beam 130 and the cross beam 140 may be respectively provided in two numbers, the extending direction of the longitudinal beam 130 is referred to as a longitudinal direction, the cross beam 140 may be perpendicular to the longitudinal beam 130, in this case, the extending direction of the cross beam 140 is perpendicular to the extending direction of the longitudinal beam 130, and the extending direction of the cross beam 140 is referred to as a transverse direction. The number of the supporting frames 100 is plural, and a plurality of the supporting frames 100 may be arranged in the transverse direction. For the same support frame 100, one end of the cross beam 140 is fixedly connected with one of the longitudinal beams 130, and the other end of the cross beam 140 is fixedly connected with the other longitudinal beam 130, so that the two cross beams 140 are longitudinally arranged at intervals. The cross beam 140 and the longitudinal beam 130 can be connected by welding, and can also be connected by bolts, buckles, rivets or integrally formed, so that the cross beam 140 and the longitudinal beam 130 cannot move relatively, i.e. the movement of the cross beam 140 and the longitudinal beam 130 is always synchronous.

The longitudinal beam 130 closest to the display module 30 may be provided with a groove 131, the groove 131 may be an annular structure, and the mounting lock 400 is disposed at the position of the groove 131, so that the mounting lock 400 is rotatably connected with the longitudinal beam 130, that is, the mounting lock 400 may rotate around the central axis of the longitudinal beam 130. Meanwhile, due to the limiting effect of the groove 131 on the mounting lock 400, the mounting lock 400 cannot slide relative to the longitudinal beam 130 in the longitudinal direction. In short, the lock 400 can only be rotated relative to the longitudinal beam 130 at the location of the recess 131. Mounting lock 400 is also interconnected to stationary lock 32, for example, both mounting lock 400 and stationary lock 32 may be removably connected, such as by bolting. When the installation lock 400 is connected to the fixing lock 32, the entire support mechanism 20 can be fixed to the display module 30, and when the installation lock 400 is released from the connection with the fixing lock 32, the entire support mechanism 20 can be detached from the display module 30.

In some embodiments, for convenience of description, two support frames 100 arranged in the transverse direction and adjacently disposed are respectively referred to as a first support frame 110 and a second support frame 120. The connecting rod 200 is a rigid structure, and the connecting rod 200 is rotatably connected between the two longitudinal beams 130 with the shortest lateral spacing distance on the first support frame 110 and the second support frame 120, i.e. one end of the connecting rod 200 is rotatably connected with the longitudinal beam 130 on the first support frame 110, and the other end of the connecting rod 200 is rotatably connected with the longitudinal beam 130 on the second support frame 120, so that the connecting rod 200 can rotate around the central axis of the longitudinal beam 130 on the first support frame 110, the connecting rod 200 can also rotate around the central axis of the longitudinal beam 130 on the second support frame 120, in short, both ends of the connecting rod 200 can rotate around the central axis extending in the longitudinal direction. The number of the links 200 between the first support bracket 110 and the second support bracket 120 may be two, two links 200 are arranged at a distance in the longitudinal direction, and the distance between the two links 200 may be relatively large, so that the connection position of the cross beam 140 on the longitudinal beam 130 is located between the two links 200. Both links 200 and stringers 130 may be directly removably attached such that links 200 may be installed on stringers 130 or removed from stringers 130.

Referring to fig. 2, 7, 9 and 10, in some embodiments, an adjusting assembly 300 is disposed between two longitudinal beams 130 of the first support frame 110 and the second support frame 120, which are closest to the display module 30, and an adjusting assembly 300 is also disposed between two longitudinal beams 130 of the first support frame 110 and the second support frame 120, which are farthest from the display module 30. The adjusting assembly 300 comprises a first adjusting rod 310 and a second adjusting rod 320, both the first adjusting rod 310 and the second adjusting rod 320 have certain rigidity, one end of the first adjusting rod 310 and one end of the second adjusting rod 320 are marked as a first end, the other end of the first adjusting rod 310 and the other end of the second adjusting rod 320 are marked as a second end, the first ends of the first adjusting rod 310 and the second adjusting rod 320 are rotatably connected with each other, so that the first ends of the first adjusting rod 310 and the second adjusting rod 320 can rotate around a central axis extending along the longitudinal direction, the second end of the first adjusting rod 310 is rotatably connected with the longitudinal beam 130 on the first support frame 110, and the second end of the first adjusting rod 310 can rotate around the central axis of the longitudinal beam 130; the second end of the second adjusting lever 320 is rotatably connected to the longitudinal beam 130 of the second support frame 100, so that the second end of the second adjusting lever 320 can rotate around the central axis of the longitudinal beam 130.

Referring to fig. 12, one of the first adjustment lever 310 and the second adjustment lever 320 is provided with a pointer 330, and the other is provided with a scale 340 for indicating a rotation angle, and when the first adjustment lever 310 and the second adjustment lever 320 rotate relatively, the pointer 330 points to different scales 340. For example, the first end of the first adjustment lever 310 is provided with a pointer 330, and the first end of the second adjustment lever 320 is provided with a scale 340, so that when the pointer 330 points to different scales 340, the rotation angle between the first adjustment lever 310 and the second adjustment lever 320 can be conveniently determined. For another example, the positions of the pointer 330 and the scale 340 are reversed, that is, the pointer 330 is disposed on the first end of the second adjustment lever 320, the scale 340 is disposed on the first end of the first adjustment lever 310, and similarly, when the pointer 330 points to different scales 340, the rotation angle between the first adjustment lever 310 and the second adjustment lever 320 can be conveniently determined.

Both the first adjustment bar 310 and the second adjustment bar 320 may be detachably connected to the longitudinal beam 130, which may facilitate loading and unloading of the entire adjustment assembly 300 on the support frame 100. The connection location of both the first adjustment bar 310 and the second adjustment bar 320 on the longitudinal beam 130 may be located between the two cross beams 140. Obviously, considering that the connection position of the cross beam 140 on the longitudinal beam 130 is located between the two connecting rods 200, the connection position of both the first adjustment lever 310 and the second adjustment lever 320 on the longitudinal beam 130 is also located between the two connecting rods 200. When two adjusting assemblies 300 are disposed on the same longitudinal beam 130, for example, two first adjusting rods 310 or two second adjusting rods 320 are connected to the same longitudinal beam 130, the two first adjusting rods 310 are longitudinally spaced apart, or the two second adjusting rods 320 are longitudinally spaced apart. In short, the attachment positions of the two first adjustment bars 310 on the longitudinal beam 130 do not coincide, or the attachment positions of the two second adjustment bars 320 on the longitudinal beam 130 do not coincide.

In some embodiments, the support frames 100 can also be arranged in a longitudinal direction, and two adjacent support frames 100 arranged in the longitudinal direction can be detachably connected. For example, for two adjacent support frames 100 arranged in the longitudinal direction, the end portions of the longitudinal beams 130 of the two support frames 100 may be fixedly connected by a fixing member. By providing the fixing member, loading and unloading between the two support frames 100 can be realized. The number of the supporting frames 100 arranged at intervals in the transverse direction may be determined according to the length of the display module 30 in the transverse direction, and then the supporting frames 100 are connected to each other through the connecting rods 200 and the adjusting assemblies 300, thereby achieving mutual splicing of the supporting frames 100 in the transverse direction. According to the length of the display module 30 in the longitudinal direction, the number of the support frames 100 arranged at intervals in the longitudinal direction can be determined, and then the support frames 100 can be spliced with each other in the longitudinal direction through the mutual connection between the longitudinal beams 130 and the longitudinal beams 130. Therefore, according to the transverse length and the longitudinal length of the display module 30, the number of the joints of the support frame 100 in the transverse direction and the longitudinal direction can be determined, and finally the size of the whole support mechanism 20 and the required number of the support frames 100, the connecting rods 200 and the adjusting assemblies 300 can be determined. Obviously, when the transverse length and the longitudinal length of the display module 30 are large, the number of the supporting frames 100, the connecting rods 200 and the adjusting assemblies 300 is increased, and the transverse length and the longitudinal length of the whole supporting mechanism 20 are increased. When the transverse length and the longitudinal length of the display module 30 are small, the number of the supporting frames 100, the connecting rods 200 and the adjusting assemblies 300 is reduced, and the transverse length and the longitudinal length of the whole supporting mechanism 20 are reduced.

In some embodiments, the support frame 100, the connecting rod 200 and the adjusting assembly 300 can be made of aluminum alloy, which has the advantages of low density and high thermal conductivity, so as to reduce the weight of the whole support mechanism 20, and facilitate the installation, transportation and storage of the support mechanism 20. On the other hand, the supporting mechanism 20 can absorb the heat in the display module 30 to a certain extent and dissipate the heat to the atmosphere, so as to improve the heat dissipation performance of the entire display panel 10. In other embodiments, the support frame 100, the connecting rod 200 and the adjusting assembly 300 may be made of stainless steel, which can improve the corrosion resistance of the support mechanism 20, prevent the support frame 100 from being corroded in the open air or in a humid environment, and ensure that the support mechanism 20 has good mechanical strength.

Referring to fig. 8, before the supporting mechanism 20 is fixed to the display module 30, the supporting mechanism 20 is in an unused state, and at this time, the whole supporting mechanism 20 can be folded, so that the whole supporting mechanism 20 is in a folded state. Specifically, the first adjustment lever 310 and the second adjustment lever 320 are rotated, and the first adjustment lever 310 and the second adjustment lever 320 are parallel to each other, that is, the angle between the first adjustment lever 310 and the second adjustment lever 320 is zero. In the process of rotating the first adjusting rod 310 and the second adjusting rod 320, the connecting rod 200 is driven to rotate relative to the supporting frames 100, the space between two adjacent supporting frames 100 is greatly reduced under the common pulling action of the first adjusting rod 310, the second adjusting rod 320 and the connecting rod 200, and then the volume of the whole supporting mechanism 20 is reduced, so that the occupied space of the supporting mechanism 20 can be reduced, and great convenience is brought to the storage and the carrying of the supporting structure. Therefore, before the support mechanism 20 is installed on the display module 30, the whole support mechanism 20 can be in a folded state, so that the support mechanism 20 can be transported; after the support mechanism 20 is unloaded from the display module 30, the entire support mechanism 20 can also be in a folded state for transportation and storage of the support mechanism 20.

Referring to fig. 12, after the first adjusting lever 310 and the second adjusting lever 320 are rotated to drive the connecting rod 200 to rotate a certain angle relative to the supporting frame 100, the supporting mechanism 20 is in a first unfolded state, at this time, the adjusting assembly 300 connected between the two longitudinal beams 130 on the first supporting frame 110 and the second supporting frame 120, which are farthest from the display module 30, is used as a reference adjusting assembly, the pointer 330 on the reference adjusting assembly points to one of the scale ranges, the scale range includes a plurality of scales 340 and is marked as a first scale range, that is, when the pointer 330 corresponds to the first scale range, the included angle between the first adjusting lever 310 and the second adjusting lever 320 on the reference adjusting assembly 300 is a first included angle, and the supporting mechanism 20 is in the first unfolded state. When the supporting mechanism 20 in the first unfolded state is mounted on the display module 30, the front surface 33 of the display module 30 will be the plane 33a, i.e. the display module 30 is a plane joint. Therefore, when the display module 30 needs to be plane-spliced, only the pointer 330 on the reference adjusting assembly needs to be made to correspond to the first scale range, so that the supporting mechanism 20 is in the first unfolded state, and then when the supporting mechanism 20 in the first unfolded state is fixed on the display module 30, the display module 30 is in the plane-spliced state.

Referring to fig. 13, after the first adjusting rod 310 and the second adjusting rod 320 are rotated to drive the connecting rod 200 to rotate a certain angle relative to the supporting frame 100, the supporting mechanism 20 is in a second unfolded state, the number of the second unfolded states may be multiple, at this time, the adjusting assembly 300 connected between the two longitudinal beams 130 on the first supporting frame 110 and the second supporting frame 120, which are farthest from the display module 30, is used as a reference adjusting assembly 300, the pointer 330 on the reference adjusting assembly 300 points to another scale range, the scale range includes multiple scales 340 and is marked as a second scale range, that is, when the pointer 330 corresponds to the second scale range, the included angle between the first adjusting rod 310 and the second adjusting rod 320 on the reference adjusting assembly 300 is a second included angle, which is smaller than the first included angle, and the supporting mechanism 20 is in the second unfolded state. When the supporting mechanism 20 in the second unfolded state is installed on the display module 30, the front surface 33 of the display module 30 will be a positive arc surface 33b, i.e. the display module 30 is a positive arc splice. Therefore, when the display module 30 needs to be spliced in a positive arc, the pointer 330 on the reference adjusting assembly 300 only needs to be made to correspond to the second scale range, so that the supporting mechanism 20 is in the second unfolded state, and then when the supporting mechanism 20 in the second unfolded state is fixed on the display module 30, the display module 30 is made to be spliced in a positive arc.

Referring to fig. 14, after the first adjusting rod 310 and the second adjusting rod 320 are rotated to drive the connecting rod 200 to rotate a certain angle relative to the supporting frame 100, the supporting mechanism 20 is in a third unfolded state, the number of the third unfolded states may be multiple, at this time, the adjusting assembly 300 connected between the two longitudinal beams 130 on the first supporting frame 110 and the second supporting frame 120, which are farthest from the display module 30, is used as a reference adjusting assembly 300, the pointer 330 on the reference adjusting assembly 300 points to another scale range, the scale range includes multiple scales 340 and is marked as a third scale range, that is, the pointer 330 corresponds to the third scale range, an included angle between the first adjusting rod 310 and the second adjusting rod 320 on the reference adjusting assembly 300 is a third included angle, the third included angle is greater than the first included angle, and the supporting mechanism 20 is in the third unfolded state. When the supporting mechanism 20 in the third unfolded state is installed on the display module 30, the front surface 33 of the display module 30 will be the reverse arc surface 33c, i.e. the display module 30 is a reverse arc splice. Therefore, when the display module 30 needs to be spliced in the reverse arc, only the pointer 330 on the reference adjusting assembly 300 needs to be made to correspond to the third scale range, so that the supporting mechanism 20 is in the third unfolded state, and then when the supporting mechanism 20 in the third unfolded state is fixed on the display module 30, the display module 30 is made to be spliced in the reverse arc.

Under the condition that supporting mechanism 20 is installed on display module assembly 30, for being suitable for different installation operating modes, when need with display module assembly 30 carry out the mutual switch-over between three concatenation states of plane concatenation state, positive arc concatenation state and anti-arc concatenation state, can rotate first regulation pole 310 again, second regulation pole 320 and connecting rod 200 to make and refer to pointer 330 on the adjusting part 300 and point to first scale scope, second scale scope or third scale scope, so can realize the quick switch-over of display module assembly 30 between above-mentioned three concatenation states.

Therefore, for the same supporting mechanism 20, the first adjusting rod 310, the second adjusting rod 320 and the connecting rod 200 can be rotated, so that the supporting mechanism 20 is in different unfolding states, and the supporting mechanism is suitable for different splicing states of the display module 30, that is, different unfolding states of the same supporting mechanism 20 can correspond to different splicing states of the same display module 30, and it is not necessary to customize a specific supporting mechanism 20 for the display module 30 in a specific splicing state, so that it is ensured that one supporting mechanism 20 can be suitable for different splicing states of the display module 30, and the universality of the supporting mechanism 20 is improved. Meanwhile, the supporting mechanism 20 is simple in structure, the supporting mechanism 20 unloaded from the display module 30 can be folded, the size of the supporting mechanism 20 can be reduced, and the convenience of the supporting mechanism 20 in the storage and transportation processes is improved.
