[0004] In the related art, the clamping groove is arranged on the side edge of the screen middle frame, and the clamping block matched with the clamping groove is arranged on the side edge of the screen rear cover. Therefore, the side edge of the screen middle frame and the side edge of the screen rear cover need to be thickened to meet the arrangement requirements of the clamping block and the clamping groove, resulting in a thick frame of the vehicle-mounted display module. SUMMARY

[0005] In order to reduce the thickness of the frame of the vehicle-mounted display module, the present application provides a display module bottom shell and a display module.

[0006] In a first aspect, the display module bottom shell provided by the present application adopts the following technical solution:

[0007] A display module bottom shell includes a rear cover and a middle frame. The rear cover and the middle frame are arranged opposite to each other. The rear cover includes a cover body and a plurality of blocking strips. The plurality of blocking strips are arranged on the side of the rear cover close to the middle frame.

The cover body is provided with a connecting piece. The frame body is provided with a connecting piece matched with the connecting piece.

[0008] Through the above technical solution, the cover body and the blocking strips collectively enclose the receiving groove, which provides a receiving space and support for the screen body. By receiving the frame body in the receiving groove, the blocking strips not only provide support for the screen body, but also provide support for the light guide plate. Therefore, the middle frame only needs to provide support for the light guide plate, and does not need to be provided with a side edge. The connection between the frame body and the rear cover is realized by the cooperation of the connecting piece and the connecting piece, thereby achieving the effect of reducing the thickness of the frame of the vehicle-mounted display module.

[0009] Preferably, the connecting piece comprises a support column, the connecting piece comprises a breaking seam, one end of the support column is fixedly connected to the side of the cover body close to the middle frame, a support hole is formed on the end of the support column close to the middle frame, the frame body is arranged on the support column, and the breaking seam penetrates through the frame body.

[0010] By adopting the above technical scheme, when the display module needs to be assembled, the middle frame is mounted on the rear cover, the side of the frame body close to the rear cover is abutted against the end surface of the support column, then the striker is used to strike and penetrate the frame body at the breaking seam of the frame body from the side of the frame body away from the rear cover, in the process of striking of the striker, the surface of the frame body is bent and the surface of the frame body is pressed into the support hole, the surface of the bent frame body is abutted against the hole wall of the support hole, thereby realizing the connection of the middle frame and the frame body.

[0011] Preferably, the connecting piece comprises a support column, the connecting piece comprises a connecting column, one end of the support column is fixedly connected to the side of the cover body close to the middle frame, a support hole is formed on the end of the support column close to the middle frame, the frame body is arranged on the support column, the connecting column is arranged on the side of the frame body close to the cover body, and the connecting column is insertedly matched with the support hole.

[0012] By adopting the above technical scheme, the connecting column is clamped into the corresponding support hole, thereby realizing the connection of the middle frame and the rear cover. Similarly, the connection of the frame body and the rear cover is realized by the mutual cooperation of the connecting column and the support hole, so that the middle frame only needs to provide support for the frame body, and the side of the middle frame does not need to be arranged, thereby realizing the effect of reducing the thickness of the frame of the vehicle-mounted display module.

[0013] Preferably, an elastic connecting sleeve is sleeved on the connecting column, and the connecting sleeve is elastically clamped and matched with the hole wall of the support hole.

[0014] By adopting the above technical scheme, the connecting sleeve is sleeved on the connecting column, so that the connecting sleeve is elastically clamped and matched with the hole wall of the support hole, thereby realizing the close connection of the frame body and the rear cover.

[0015] Preferably, the connecting piece comprises a positioning block, the positioning block is arranged on the side of the frame body close to the cover body, a positioning hole is formed on the positioning block, and a positioning column matched with the positioning hole is fixedly arranged on the groove wall of the accommodating groove.

[0016] By adopting the above technical scheme, the mutual cooperation of the positioning hole and the positioning block can realize the close connection of the frame body and the rear cover, and meanwhile, since the positioning column is arranged on the groove wall of the accommodating groove, the middle frame only needs to provide support for the frame body, and the light guide plate is limited and supported by the blocking strip, thereby reducing the thickness of the frame of the vehicle-mounted display module in the way of reducing the thickness of the middle frame.

[0017] Preferably, the connecting piece comprises a positioning block, the positioning block comprises a connecting part and a positioning part, one end of the connecting part is fixedly connected with the outer frame surface of the frame body, the positioning part is fixedly connected with the end of the connecting part away from the frame body, the blocking strip is provided with a gap for positioning which cooperates with the connecting part, the positioning part is provided with a positioning hole, and the side wall of the blocking strip away from the side wall of the accommodating groove is fixedly provided with a positioning column which cooperates with the positioning hole.

[0018] By adopting the above technical scheme, the positioning column is fixedly arranged on the blocking strip, and the positioning hole is arranged on the positioning part, the cooperation between the positioning hole and the positioning column can make the frame body and the rear cover be connected closely. By arranging the positioning column on the side of the blocking strip away from the side wall of the accommodating groove, the interference between the positioning column and the screen body accommodated in the accommodating groove can be reduced, and the gap for positioning is arranged to facilitate the positioning part to extend out of the accommodating groove.

[0019] Preferably, the middle frame further comprises a plurality of limiting strips, the plurality of limiting strips are fixedly arranged on the side of the middle frame away from the rear cover, the plurality of limiting strips jointly enclose to form a mounting groove, one end of each limiting strip away from the frame body is fixedly connected with a limiting block, and the limiting block abuts against the side of the blocking strip away from the cover body.

[0020] By adopting the above technical scheme, when the middle frame is mounted on the rear cover, the limiting strip provides support for the limiting block, and the limiting block is overlapped on the blocking strip, so that the middle frame can be stably mounted on the rear cover, and the occurrence of the collapse of the middle frame to the groove bottom of the accommodating groove due to the impact on the screen is reduced.

[0021] Preferably, the limiting strip is provided with a deformation gap, and the deformation gap penetrates through both ends in the thickness direction of the limiting strip.

[0022] By adopting the above technical scheme, the deformation gap is arranged to facilitate the deformation and bending of the middle frame. When the light guide plate is mounted in the mounting groove, the middle frame deforms, and according to the stress concentration effect, the deformation will occur at the position where the deformation gap is arranged, so as to reduce the destructive deformation of the middle frame or the damage of the screen body caused by the deformation of the middle frame.

[0023] Preferably, the thickness of the limiting strip is H, and 0.15mm≤H≤0.45mm.

[0024] By adopting the technical scheme, the thickness of the limiting strip is the thickness occupied by the middle frame, so when H>0.45mm, the thickness of the limiting strip is thick, and it is difficult to reduce the thickness of the vehicle display module frame; when H<0.15mm, the structural strength of the limiting strip is low, so that the frame is easy to deform, and the effect of the limiting strip is weakened, and it is difficult to support the light guide plate well; when 0.15mm≤H≤0.45mm, the structural strength requirements of the limiting strip and the middle frame can be met, and the thickness of the vehicle display module frame can be reduced.

[0025] In a second aspect, the display module provided by the present application adopts the following technical scheme:

[0026] A display module, comprising any one of the display module bottom shells.

[0027] Since the display module adopts any one of the display module bottom shells, the display module has the same beneficial effects as the display module bottom shell, and details are not repeated here.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. By accommodating the frame in the accommodation groove, the blocking strip not only provides support for the screen body, but also provides support for the light guide plate, so that the middle frame only needs to provide support for the light guide plate, and the side of the middle frame does not need to be provided, and the connection between the frame and the rear cover is realized by the cooperation of the connecting piece and the connecting piece, thereby realizing the effect of reducing the thickness of the vehicle display module frame;

[0030] 2. The cooperation of the positioning hole and the positioning block can make the frame and the rear cover connect closely, and since the positioning column is arranged on the groove wall of the accommodation groove, the middle frame only needs to provide support for the frame, and the blocking strip limits and supports the light guide plate, thereby reducing the thickness of the vehicle display module frame by reducing the thickness of the middle frame;

[0031] 3. The deformation gap is convenient for the middle frame to deform and bend. When the light guide plate is installed into the mounting groove, the middle frame deforms, and according to the stress concentration effect, deformation will occur at the position where the deformation gap is opened, reducing the destructive deformation of the middle frame, or the screen body is damaged due to the deformation of the middle frame.

[0043] Referring to Figure 1 The back cover 1 includes a cover body 11 and a plurality of blocking strips 12, the plurality of blocking strips 12 are integrally formed on one side of the cover body 11 close to the middle frame 2, in the embodiment, the number of the blocking strips 12 is four, the four blocking strips 12 are arranged at the edges of the four sides of the back cover 1 respectively, and the four blocking strips 12 are sequentially connected end to end, so that the four blocking strips 12 and the back cover 1 jointly form an accommodating groove 13, and the opening of the accommodating groove 13 faces one side of the middle frame 2, so as to accommodate and fix the screen body.

[0044] Referring to Figure 1 and Figure 2The middle frame 2 comprises a frame body 21, and the cover body 11 is provided with a connecting piece 3 on a side close to the middle frame 2. In the embodiment, the connecting piece 3 is a support column 31, and the number of the support columns 31 is four. The four support columns 31 are riveted to the cover body 11, and the four support columns 31 are respectively located at four corner edges of the cover body 11. A support hole 311 is formed in each support column 31 along an axial direction of the corresponding support column 31. The middle frame 2 is accommodated in the accommodating groove 13 and supported on the support columns 31. The middle frame 2 is provided with an interface connecting piece 4 matched with the connecting piece 3. In the embodiment, the interface connecting piece 4 is a breaking seam 41 formed in the middle frame 2 at a position corresponding to the support column 31. The breaking seam 41 is a cross-shaped seam and penetrates the middle frame 2 along a thickness direction of the middle frame 2.

[0045] When the display module needs to be assembled, the screen body is placed into the accommodating groove 13, and then the middle frame 2 is installed on the rear cover 1, so that a side of the frame body 21 close to the rear cover 1 abuts against an end surface of the support column 31. Then, a striker is used to strike and penetrate the frame body 21 at the breaking seam 41 on the frame body 21 from a side of the frame body 21 away from the rear cover 1. In the process of the striking of the striker, the surface of the frame body 21 is bent and the surface of the frame body 21 is riveted into the support hole 311, so that the bent surface of the frame body 21 abuts against a hole wall of the support hole 311 closely, thereby realizing the connection between the middle frame 2 and the frame body 21.

[0046] By accommodating the frame body 21 in the accommodating groove 13, the blocking strip 12 not only supports the screen body but also supports the light guide plate, so that the middle frame 2 only needs to support the light guide plate, and the side edge of the middle frame 2 is not needed. The connection between the frame body 21 and the rear cover 1 is realized by the cooperation of the connecting piece 3 and the interface connecting piece 4, thereby realizing the effect of reducing the thickness of the frame of the vehicle-mounted display module.

[0047] Embodiment 2

[0048] With reference to Figure 3 The difference between the embodiment and the embodiment 1 is that the interface connecting piece 4 is different. In the embodiment, the interface connecting piece 4 is a connecting column 42, and the number of the connecting columns 42 is four. The four connecting columns 42 are riveted to a side of the middle frame 2 close to the cover body 11, and the four connecting columns 42 are respectively located at four corner edges of the middle frame 2. The connecting column 42 is elastically clamped and matched with the support hole 311. The connecting column 42 is fixedly sleeved with an elastic connecting sleeve 421. The connecting sleeve 421 is preferably made of silica gel. The connecting sleeve 421 comprises a plurality of connecting segments. The connecting segments are circular truncated cone-shaped. The diameter of a larger cross section of the connecting segment is slightly larger than the hole diameter of the support hole 311. The diameter of a smaller cross section of the connecting segment is slightly smaller than the hole diameter of the support hole 311. The plurality of connecting segments are sequentially and circularly connected along an axial direction of the connecting segment, and the larger cross section of each connecting segment is towards the frame body 21.

[0049] The connection sleeve 421 is in close abutment with the hole wall of the support hole 311 by clamping the connecting column 42 into the corresponding support hole 311, so that the connection of the middle frame 2 and the rear cover 1 is realized. Similarly, the connection of the frame body 21 and the rear cover 1 is realized by the cooperation of the connecting column 42 and the support hole 311, so that the middle frame 2 only needs to provide support for the light guide plate, and the side of the middle frame 2 does not need to be provided, thereby realizing the effect of reducing the thickness of the frame of the vehicle-mounted display module.

[0050] Embodiment 3:

[0051] With reference to Figure 4 The difference between this embodiment and embodiment 1 is that the middle frame 2, the connecting piece 3 and the connecting piece 4 are different. The middle frame 2 further comprises a plurality of limiting strips 22 which are integrally formed on the side of the middle frame 2 away from the rear cover 1. In this embodiment, the number of limiting strips 22 is four, and the four limiting strips 22 are respectively located at the edges of the four outer sides of the frame body 21, and the limiting strips 22 are sequentially connected end to end, so that the four limiting strips 22 and the frame body 21 together enclose the mounting groove to accommodate and fix the light guide plate. In this embodiment, the middle frame 2 is made by sheet metal process, so the thickness H of the frame body 21 and the limiting strip 22 is 0.15mm. In other embodiments of the present application, H can also be 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm and 0.45mm.

[0052] With reference to Figure 4 Each limiting strip 22 integrally forms a plurality of limiting blocks 23 at the end away from the frame body 21. In this embodiment, four limiting blocks 23 are integrally formed on the limiting strip 22 on the long side of the frame body 21, and the four limiting blocks 23 are spaced apart along the length direction of the limiting strip 22 on the long side of the frame body 21. Three limiting blocks 23 are integrally formed on the limiting strip 22 on the short side of the frame body 21, and the three limiting blocks 23 are spaced apart along the length direction of the limiting strip 22 on the short side of the frame body 21. One end of each limiting block 23 is fixedly connected with the corresponding limiting strip 22, and the other end extends away from the inner frame surface of the frame body 21.

[0053] With reference to Figure 4 The connecting piece 4 comprises a positioning block 43, and the connecting piece 3 comprises a positioning column 32. The positioning block 43 is integrally formed on one limiting strip 22 on the long side of the frame body 21 close to the rear cover 1, one end of the positioning block 43 is connected with the frame body 21, and the other end extends to the side of the rear cover 1. The positioning block 43 is provided with a positioning hole 431 which penetrates through the positioning block 43 along the thickness direction of the positioning block 43. The positioning column 32 is fixedly arranged on one limiting strip 22 on the long side of the cover body 11, the positioning column 32 is in clamping cooperation with the positioning hole 431, and the end of the positioning column 32 away from the limiting strip 22 is in arc transition with the side surface of the positioning column 32.

[0054] Referring to Figure 4 When assembling the display module, the screen body is placed into the accommodating groove 13, and then the middle frame 2 is installed onto the back cover 1, so that the side of the frame body 21 close to the back cover 1 abuts against the screen body, the side of the limiting strip 22 abuts against the side of the blocking strip 12, the side of the limiting block 23 close to the frame body 21 abuts against the end face of the blocking strip 12, and the positioning column 32 is clamped into the positioning hole 431, and then the light guide plate is installed into the installation groove, and since the size of the light guide plate is slightly larger than the size of the installation groove, the middle frame 2 is deformed, so that the light guide plate, the middle frame 2 and the back cover 1 are connected closely. Finally, the PCB board is installed onto the side of the back cover 1 away from the middle frame 2, that is, the installation of the display module is realized. Since the limiting block 23 of the middle frame 2 overlaps on the back cover 1 when the installation is completed, and the frame body 21 is partially accommodated in the accommodating groove 13, the thickness of the limiting strip 22 is the thickness occupied by the middle frame 2, and the thickness of the middle frame 2 can be reduced by making the limiting strip 22 thin.

[0055] Embodiment 4

[0056] Referring to Figure 5 The difference between the present embodiment and embodiment 3 is that the positioning block 43 and the back cover 1 are different. In the present embodiment, the positioning block 43 comprises a connecting portion 432 and a positioning portion 433 perpendicular to each other, one end of the positioning portion 433 in the width direction is fixedly connected with one end of the connecting portion 432 in the width direction, the end of the connecting portion 432 away from the positioning portion 433 is fixedly connected with the outer frame surface of the frame body 21, and the positioning portion 433 extends to the side of the frame body 21, and the positioning hole 431 is formed on the positioning portion 433. The limiting strip 22 on one long side of the cover body 11 is provided with a gap notch 221 matched with the connecting portion 432, and the positioning column 32 is integrally formed on the outer side surface of the limiting strip 22.

[0057] When assembling the display module, the screen body is placed into the accommodating groove 13, and then the middle frame 2 is installed onto the back cover 1, so that the side of the frame body 21 close to the back cover 1 abuts against the screen body, the side of the limiting strip 22 abuts against the side of the blocking strip 12, the side of the limiting block 23 close to the frame body 21 abuts against the end face of the blocking strip 12, and the positioning column 32 is clamped into the positioning hole 431, and then the light guide plate is installed into the installation groove, and since the size of the light guide plate is slightly larger than the size of the installation groove, the middle frame 2 is deformed, so that the light guide plate, the middle frame 2 and the back cover 1 are connected closely. Finally, the PCB board is installed onto the side of the back cover 1 away from the middle frame 2, that is, the installation of the display module is realized. Since the limiting block 23 of the middle frame 2 overlaps on the back cover 1 when the installation is completed, and the frame body 21 is partially accommodated in the accommodating groove 13, the thickness of the limiting strip 22 is the thickness occupied by the middle frame 2, and the thickness of the middle frame 2 can be reduced by making the limiting strip 22 thin.
