Description

Technical Field

[0001] The utility model relates to display technology, in particular to a backlight rubber mount and a vehicle-mounted display module. Background Art

[0002] A vehicle-mounted display module mainly consists of a protection cover plate, a liquid crystal panel and a backlight module. After the liquid crystal panel is fixedly pasted on the back surface of the protection cover plate through OCA optical glue, the backlight module is then fixedly pasted on the back surface of the protection cover plate through double-sided tape. The backlight module includes a rubber mount, and the rubber mount is used for pasting the double-sided tape to be fixedly pasted with the protection cover plate.

[0003] Currently, in order to increase the screen-to-body ratio of the vehicle-mounted display module and achieve a narrow border of the vehicle-mounted display module, the width of the rubber mount of the backlight module is made narrower and narrower, which results in a smaller area available for pasting the double-sided tape on the rubber mount, thereby reducing the stability of the fixed paste between the backlight module and the protection cover plate.

[0004] The paste strength of the glue is greater than that of the double-sided tape, so the glue can be used to replace the double-sided tape to achieve the paste fixation between the backlight module and the protection cover plate in a narrow-border module.

[0005] However, the glue has fluidity before curing and is prone to the problem of glue overflow, thus affecting the structure and appearance of the product. Summary of the Utility Model

[0006] In order to solve the above deficiencies of the prior art, the utility model provides a backlight rubber mount, which can avoid the problem of glue overflow.

[0007] The utility model also provides a vehicle-mounted display module, including the above backlight rubber mount.

[0017] Furthermore, the maximum diameter of the glue inlet is 1.2 - 2.0 mm.

[0018] Furthermore, the diameter of the air outlet gradually increases from the end close to the exhaust channel to the end far from the exhaust channel.

[0031] Embodiment 1

[0032] As Figure 1 and 2As shown, a backlight adhesive holder includes:

[0033] An adhesive holder body 310;

[0034] The adhesive holder body 310 includes at least one pasting part 311. At least one glue injection channel 312 and at least one exhaust channel 313 are provided inside the pasting part 311. The glue outlet of the glue injection channel 312 and the air inlet of the exhaust channel 313 are arranged on the pasting surface of the pasting part 311, and the glue inlet 3120 of the glue injection channel 312 and the air outlet 3130 of the exhaust channel 313 are arranged on the non-pasting surface of the pasting part 311. A diversion groove 314 is provided on the pasting surface of the pasting part 311. The glue outlet of the glue injection channel 312 is communicated with the air inlet of the exhaust channel 313 through the diversion groove 314.

[0035] The backlight adhesive holder of the present utility model is used to paste and fix the backlight module on the back surface of the protection cover plate through glue. By providing the diversion groove 314 on the pasting surface of the pasting part 311 of the adhesive holder body 310 for injecting the glue, the two side walls of the diversion groove 314 are used to block the glue before curing, so as to avoid the glue overflowing before curing, thus avoiding the problem of glue overflow. At the same time, the glue is injected into the diversion groove 314 from the non-pasting surface of the pasting part 311 by using the glue injection channel 312, and during the glue injection process, the air in the diversion groove 314 is discharged from the non-pasting surface of the pasting part 311 by using the exhaust channel 313, so as to improve the glue injection efficiency and avoid air bubble residue.

[0036] When the backlight module is paste-fixed to the protection cover plate, the side surface of the pasting part 311 facing the protection cover plate is the pasting surface, and the other side surfaces facing away from the protection cover plate or perpendicular or inclined to the protection cover plate are the non-pasting surfaces.

[0037] Preferably, both the glue injection channel 312 and the exhaust channel 313 are straight channels to reduce the resistance during glue injection and exhaust, that is, the glue inlet 3120 of the glue injection channel 312 and the air outlet 3130 of the exhaust channel 313 are both arranged on the non-pasting surface opposite to the pasting surface.

[0038] The adhesive holder body 310 can adopt a traditional circular adhesive holder or a rectangular adhesive holder, or can adopt a special-shaped adhesive holder according to the actual needs of the in-vehicle display module. As Figure 1 shown, the number of the pasting parts 311 can be one, which is arranged on the entire peripheral area of the adhesive holder body 310, as Figure 3 and 4As shown, the number of the pasting parts 311 can also be multiple, such as two or four, which are evenly spaced and arranged on a partial peripheral area of the glue rack body 310.

[0039] In this embodiment, the groove depth of the diversion groove 314 is 0.1 - 0.3 mm, the width of the diversion groove 314 is 1.0 - 1.4 mm, and the diameters of the glue injection channel 312 and the exhaust channel 313 are 0.8 - 1.2 mm.

[0040] Preferably, the diameter of the glue inlet 3120 gradually increases from the end close to the glue injection channel 312 to the end far from the glue injection channel 312.

[0041] In this embodiment, the minimum diameter of the glue inlet 3120 is the diameter of the glue injection channel 312, and the maximum diameter of the glue inlet 3120 is 1.2 - 2.0 mm.

[0042] Preferably, the diameter of the air outlet 3130 gradually increases from the end close to the exhaust channel 313 to the end far from the exhaust channel 313.

[0043] In this embodiment, the minimum diameter of the air outlet 3130 is the diameter of the exhaust channel 313, and the maximum diameter of the air outlet 3130 is 1.2 - 2.0 mm.

[0044] Embodiment Two

[0045] As Figure 5 shown, a vehicle-mounted display module includes a protection cover plate 10, a liquid crystal panel 20, and a backlight module 30. The liquid crystal panel 20 is fixedly pasted on the back surface of the protection cover plate 10; the backlight module 30 includes the backlight glue rack 31 described in Embodiment One, glue 32 is injected into the diversion groove 314 of the backlight glue rack 31, and the backlight module 30 is fixedly pasted on the back surface of the protection cover plate 10 through the glue 32 in the backlight glue rack 31.

[0046] The in-vehicle display module of the present utility model uses glue 32 with greater bonding strength to replace the traditional double-sided tape, so as to paste and fix the backlight module 30 on the back surface of the protection cover plate 10. By providing the flow guide groove 314 on the bonding surface of the bonding part 311 of the backlight glue holder 31 for injecting the glue 32, the two side walls of the flow guide groove 314 are used to block the glue 32 before curing, so as to avoid the overflow of the glue 32 before curing, thereby avoiding the problem of glue overflow. At the same time, the glue 32 is injected into the flow guide groove 314 from the non-bonding surface of the bonding part 311 through the glue injection channel 312. During the glue injection process, the air in the flow guide groove 314 is discharged from the non-bonding surface of the bonding part 311 through the exhaust channel 313, so as to improve the glue injection efficiency and avoid the residue of air bubbles.

[0047] In this embodiment, the liquid crystal panel 20 is paste-fixed on the back surface of the protection cover plate 10 through OCA optical glue; the backlight glue holder 31 of the backlight module 30 is located on the periphery of the liquid crystal panel 20.

[0048] The glue 32 can be but is not limited to epoxy resin.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present utility model and are not intended to limit them. Although the embodiments of the present utility model have been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the embodiments of the present utility model can still be modified or equivalently replaced, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
