[0024] The protective support of the present embodiment is used for the display module in the carrying process. The display module includes a display panel, a polarizer is arranged on the light-emitting side of the display panel, a cover plate is arranged on the side of the polarizer away from the display panel, a back film layer and a support layer are sequentially arranged on the backlight side of the display panel in the direction away from the display panel, the support layer at least includes a first metal support plate and a second metal support plate stacked, the materials of the first metal support plate and the second metal support plate can be the same or different, and exemplarily, the first metal support plate and the second metal support plate are both made of aluminum alloy.

[0025] Reference Figure 4The display module includes a display area 10 and a binding area 20, and a bendable area 30 is arranged between the display area 10 and the binding area 20. The bendable area 30 is bent so that the binding area 20 is located on the backlight side of the display module. The binding area 20 is bound to a chip-on-film, and the display area 10 is connected to a main circuit board located on the backlight side of the display module through the chip-on-film.

[0026] During transportation, the bendable area, the binding area, the chip-on-film and other structures are exposed and are easily subjected to extrusion and collision, thereby causing internal circuit rupture and leading to poor display of the screen body. Therefore, the protection bracket provided in the embodiment can be used to protect the display module in the transportation process and other environments.

[0027] The protection bracket provided in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-4 The protection bracket provided in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0029] The main body part includes a first part 11 and a second part 12 in a first direction (X direction in the reference Figure 1 The first part 11 and the second part 12 are movably connected through an adjusting component 5 so that the distance between the first part 11 and the second part 12 in the first direction is adjustable.

[0030] The clamping part includes a first clamping piece 21 and a second clamping piece 22 arranged oppositely in the first direction. In the first direction, the first clamping piece 21 is arranged on the side of the first part 11 away from the second part 12, and the second clamping piece 22 is arranged on the side of the second part 12 away from the first part 11. The first clamping piece 21 and the second clamping piece 22 are located on the same side of the main body part, so that the first clamping piece 21, the second clamping piece 22 and the main body part form a clamping space for clamping the flexible display module.

[0031] In use, the protection bracket is mounted on the display module, the first direction is perpendicular to the direction from the display area to the bendable area, the display module is clamped in the clamping space, and the first clamping piece 21 and the second clamping piece 22 are located on opposite sides of the display module in the first direction to clamp and fix the display module. The main body part covers the backlight side of the display module, and the orthographic projection of the main body part on the display module covers at least the binding area and the chip on film. In some embodiments, the orthographic projection of the main body part on the display module also covers the main circuit board. In actual application, the area of the main body part can be set according to actual needs. When the display module needs to be assembled with other components into a complete machine, the protection bracket can be removed.

[0032] In this embodiment, the main body part includes the first part 11 and the second part 12 connected movably. When assembling with the display module, the first part 11 and the second part 12 can be placed on opposite sides of the display module in the first direction, and then the first part 11 and the second part 12 are controlled to move towards each other. After the first clamping piece 21 and the second clamping piece 22 are clamped on both sides of the display module, the first part 11 and the second part 12 are fixed by the adjusting component 5.

[0033] For example, the adjusting component 5 is a resilient structure. When the protection bracket is assembled with the display module, the first part 11 and the second part 12 are controlled to move away from each other under the elastic action of the resilient structure, so as to increase the width of the clamping space in the first direction. When the display module is located in the clamping space, the first part 11 and the second part 12 are controlled to move towards each other, and the display module is clamped by the first clamping piece 21 and the second clamping piece 22.

[0034] It should be noted that in the embodiment in which the adjusting component 5 is a resilient structure, after the protection bracket is assembled with the display module, the resilient structure is in a deformed state to clamp and fix the display module by elastic action.

[0035] It should be noted that in the embodiment in which the adjusting component 5 is a resilient structure, the deformation amount of the resilient structure can be set according to actual needs.

[0036] Through the setting of the adjusting component 5, the application range of the protection bracket can be expanded, so that the protection bracket provided by the embodiment can not only meet the corresponding protection function, but also has a certain universality and can meet the size requirements of most vehicle-mounted display screens. Through the protection of the protection bracket of the embodiment, on the one hand, the yield of the display module production is improved, and on the other hand, the use efficiency of the protection bracket is improved, which has important significance for reducing the overall cost and vehicle-mounted display.

[0037] In some embodiments, the first part 11 and the second part 12 are of the same structure (but not limited thereto, the first part 11 and the second part 12 can also be of different structures), and both the first part 11 and the second part 12 are of a plate structure.

[0038] It should be noted that when clamping the display module, the gap between the first part 11 and the second part 12 in the first direction is less than a preset value, and in some embodiments, the first part 11 and the second part 12 can be in contact to better protect the corresponding structure of the display module.

[0039] The preset value can be set according to actual needs, for example, it can be 5-10mm, but not limited thereto.

[0040] In some embodiments, the first part 11 is provided with a first clamping member, the second part 12 is provided with a second clamping member, and the adjusting component 5 is clamped between the first clamping member and the second clamping member.

[0041] Reference Figure 3 In some embodiments, the adjusting component 5 includes at least one spring arranged between the first part 11 and the second part 12, and the deformation direction of the spring is parallel to the first direction.

[0042] When the adjusting component 5 includes at least two springs, the at least two springs are arranged in a second direction (reference Figure 1 Y direction in the figure) perpendicular to the first direction.

[0043] It should be noted that the main body part includes a center line extending along the first direction, in order to ensure the uniformity of the stress of the first part 11 and the second part 12, when the number of springs is odd, the adjusting component 5 includes a center spring, or the adjusting component 5 includes a center spring and edge springs symmetrically arranged on opposite sides of the center spring in the second direction. Wherein, the axial center line of the center spring coincides with the center line of the main body part. When the number of springs is even, the adjusting component 5 includes at least two springs, and the at least two springs are symmetrically arranged on both sides of the center line.

[0044] Reference Figure 1 and Figure 2 In some embodiments, the adjusting component 5 comprises at least one elastic ring arranged between the first part 11 and the second part 12, and buckles corresponding to the elastic ring are arranged on the first part 11 and the second part 12 respectively.

[0045] For example, the elastic ring can be a rubber band, but is not limited thereto.

[0046] It should be noted that the main body part comprises a center line extending along the first direction, in order to ensure the uniformity of the stress of the first part 11 and the second part 12, when the number of the elastic ring is odd, the adjusting component 5 comprises a center elastic ring, or the adjusting component 5 comprises a center elastic ring and edge elastic rings symmetrically arranged on opposite sides of the center elastic ring in the second direction. Wherein, the axial center line of the center elastic ring coincides with the center line of the main body part. When the number of the elastic ring is even, the adjusting component 5 comprises at least two elastic rings, and the at least two elastic rings are symmetrically arranged on both sides of the center line.

[0047] For example, the structure of the first clamping member and the second clamping member can be the same, the first clamping member comprises a fixed column and a limiting boss arranged on the side of the fixed column away from the first part 11, and the orthogonal projection of the limiting boss on the first part 11 is larger than the orthogonal projection of the fixed column on the first part 11.

[0048] The spring or the elastic ring is connected to the corresponding fixed column, and the limiting boss plays a role of preventing the spring or the elastic ring from being separated.

[0049] For example, the first clamping member 21 and the second clamping member 22 are symmetrically arranged on opposite sides of the main body part, the first clamping member 21 comprises at least one clamping rod, and the extension direction of the clamping member is perpendicular to the main body part.

[0050] When the first clamping member 21 comprises two or more clamping rods, the two or more clamping members are arranged at intervals in the second direction (perpendicular to the first direction).

[0051] It should be noted that the length of the clamping rod is greater than the thickness of the display module, so as to better clamp and fix the display module.

[0052] For example, the first clamping member 21 and the first part 11 can be an integral structure, and the second clamping member 22 and the second part 12 can be an integral structure, but are not limited thereto.

[0053] Exemplarily, one of the first clamping member 21 and the second clamping member 22 is provided with an elastic buffer layer on the side facing the other clamping member, so as to avoid damaging the display module.

[0054] The elastic buffer layer can be a foam, but is not limited thereto.

[0055] In some embodiments, the protection support further comprises a fixing portion 3, which is arranged at the first end of the main body portion in the second direction, and one side of the fixing portion 3 is provided with an adhesive layer for bonding the backlight side of the flexible display module, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the thickness direction of the main body portion.

[0056] The arrangement of the fixing portion 3 can increase the connection stability of the protection support and the display module.

[0057] It should be noted that, in the second direction, the fixing portion 3 is located at one end of the main body portion, and after the protection support and the display module are assembled, the fixing portion 3 is located at the first area of the display module, and in the second direction, the first area is located on one side of the main circuit board 7.

[0058] In some embodiments, in the first direction, the main body portion has two oppositely arranged edge areas, and in the second direction, each of the edge areas extends outward to form the fixing portion 3. That is, in the first direction, the first portion 11 is provided with the fixing portion 3 away from one end of the second portion 12, and the second portion 12 is provided with the fixing portion 3 away from one end of the first portion 11.

[0059] Correspondingly, the fixing portion 3 can be formed by outward extension of part of the first portion 11 or part of the second portion 12. In the first direction, the fixing portion 3 is located at the edge of the main body portion, avoiding interference with the corresponding devices arranged on the display module, and reducing the cost.

[0060] When the protection support and the display module are assembled, in the second direction, the two fixing portions can be located on opposite sides of the main circuit board 7, as shown in Figure 2 but is not limited thereto.

[0061] The main body portion of the protection support covers the backlight side of the display module, the binding area of the display module is bent to the backlight side of the display module and connected with the main circuit board located on the backlight side of the display module, so that the backlight side of the display module is not a plane and has a step difference. In some embodiments, a transition portion 4 is arranged between the fixing portion 3 and the main body portion, the main body portion and the fixing portion 3 are arranged in parallel, the transition portion 4 is arranged obliquely, and the fixing portion 3 and the clamping portion are located on the same side of the main body portion.

[0062] In some embodiments, the main body part is provided with a protective cover 6 on the side away from the clamping part in the thickness direction of the main body part, and the first part 11 and the second part 12 are slidably arranged in the protective cover 6.

[0063] The first part 11 and the second part 12 are arranged by the adjusting component 5, so that the clamping distance of the first part 11 and the second part 12 in the first direction is adjustable, and the protective cover 6 is arranged to protect the adjusting component 5 and make the appearance of the protective bracket beautiful.

[0064] For example, the protective cover 6 has a bottom plate and side plates on opposite sides of the bottom plate, the side plates are provided with rails extending in the first direction, and the first part 11 and the second part 12 are slidably connected in the rails.

[0065] For example, the protective cover 6 is provided with a limiting block at both ends in the first direction to prevent the first part 11 and the second part 12 from being separated from the protective cover 6.

[0066] For example, the protective cover 6 is a sleeve, the sleeve is sleeved outside the first part 11 and the second part 12, and the sleeve is provided with a stop plate at both ends in the axial direction to prevent the first part 11 and the second part 12 from sliding out of the sleeve.

[0067] In some embodiments, at least one supporting component 101 is arranged at the corner of the first part 11, at least one supporting component 101 is arranged at the corner of the second part 12, and the supporting component 101 is located in the clamping space.

[0068] The supporting component 101 can be an integral structure with the corresponding first part 11 or second part 12, and the arrangement of the supporting component 101 can avoid the whole main body part from being attached to the corresponding area of the display module. When impacted, the protective bracket can play a buffering role.

[0069] For example, the supporting component 101 has a gap with the display module, and the gap can be zero.

[0070] For example, the supporting component 101 is covered with an elastic buffer layer outside the end away from the main body part, and the elastic buffer layer can be foam, rubber, etc.

[0071] The main circuit board and the structure such as the chip on film of the display module are exposed, and the main body part can be used for protection. In the second direction, the bendable area of the display module is located on one side of the display area, and the bendable area is distributed with metal traces. In order to protect the bendable area, in some embodiments, in the second direction, the second end of the main body part is provided with an auxiliary protection part 102, the auxiliary protection part 102 and the clamping part are located on the same side of the main body part, and the main body part and the auxiliary protection part 102 are arranged at an angle, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the thickness direction of the main body part.

[0072] For example, the auxiliary protection structure can be a plate structure, and the main body part and the auxiliary protection part 102 are arranged perpendicularly, but it is not limited thereto. For example, the angle between the main body part and the auxiliary protection part 102 can be 80-100 degrees.

[0073] For example, the auxiliary protection part 102 includes a third part corresponding to the first part 11 and a fourth part corresponding to the second part 12. The third part and the first part 11 can be an integral structure, and the fourth part and the second part 12 can be an integral structure.

[0074] It should be noted that after the protection support and the display module are assembled, the auxiliary protection part 102 and the bendable area of the display module have a gap, and the gap is arranged to avoid damage to the bendable area by the protection support.

[0075] For example, in the second direction, the second end of the main body part extends outward to form a limiting part 103.

[0076] When transporting, the protection support and the display module are assembled and placed in the corresponding placement cavity. The limiting part 103 protects the auxiliary protection part 102, and when the protection support is subjected to external force, the auxiliary protection part 102 can be directly stressed, thereby effectively protecting the bendable area of the display module.

[0077] It can be understood that the above embodiments are only exemplary embodiments adopted for illustrating the principles of the present application, and the present application is not limited thereto. Various modifications and improvements can be made by those skilled in the art without departing from the spirit and essence of the present application, and these modifications and improvements are also considered as the protection scope of the present application.
