[0038] Embodiment 1
[0039] Reference Figures 1-8The embodiment provides a vehicle-mounted display screen, which is an all-in-one machine structure and comprises a full-laminated screen assembly 10, a rear shell 40 and a vehicle-mounted support 30; the rear shell 40 has a containing cavity, the full-laminated screen assembly 10 is installed in the containing cavity, and the full-laminated screen assembly 10 is connected with the rear shell 40 through a plurality of buckle assemblies.
[0040] The rear part of the full-laminated screen assembly 10 is provided with a die-casting backlight rear shell 11, the die-casting backlight rear shell 11 is connected with the vehicle-mounted support 30, a buffer layer 20 is arranged between the die-casting backlight rear shell 11 and the rear shell 40, the die-casting backlight rear shell 11 and the rear shell 40 are fixedly connected through a plurality of screws 70, and a window 45 is formed in the rear shell 40 and used for penetrating the vehicle-mounted support 30, so that the vehicle-mounted support 30 can be connected with a vehicle body after being assembled.
[0041] The vehicle-mounted support 30 can be formed by die casting, and the die-casting backlight rear shell 11 can be made of an aluminum-magnesium alloy or an aluminum alloy.
[0042] The buffer layer 20 can be made of a flexible material, such as flexible plastic or soft rubber, and the buffer layer 20 can also be made of double-sided adhesive tape, which can not only play a buffering role but also make the full-laminated screen assembly 10 and the rear shell 40 be first bonded through the double-sided adhesive tape and then be fixedly connected through the plurality of screws 70, so that the connecting effect and the connecting stability are improved and loosening is avoided.
[0043] The buckle assembly comprises matched buckles 41 and slots 12, a plurality of buckles 41 are arranged around the rear shell 40, a plurality of slots 12 are arranged around the die-casting backlight rear shell 11, the buckles 41 and the slots 12 are arranged in one-to-one correspondence, and when the rear shell 40 and the full-laminated screen assembly 10 are assembled, the buckles 41 are buckled in the slots 12, so that the assembly reliability is ensured.
[0044] The rear part of the die-casting backlight rear shell 11 is provided with a screen driving board 15 (TCON board), and the vehicle-mounted support 30 is arranged in a position corresponding to the TCON board.
[0045] The rear shell 40 can be made of plastic material, and the buckles 41 can be achieved by machining, so that the gap in the actual assembly process is adjustable, or the buckles 41 and the rear shell 40 are integrally injection molded, which is convenient for manufacturing. In addition, such a design can position the rear shell 40 through the buckles 41 to avoid the problem that the assembly gap of the full-lamination screen assembly 10 and the rear shell 40 cannot be controlled during assembly; because the buckles 41 simply rely on the cooperation of the full-lamination screen assembly 10 and the rear shell 40, it is impossible to completely avoid the abnormal noise problem caused by the deformation of the plastic, so a buffer layer 20 is designed between the plastic rear shell 40 and the die-cast backlight rear shell 11 to avoid the abnormal noise problem. The buffer layer 20 is preferably double-sided adhesive tape. This adhesive method not only solves the abnormal noise problem, but also meets the force requirement of the full-lamination screen assembly 10 through calculation during design; the die-cast backlight rear shell 11 of the full-lamination screen assembly 10 has a circuit board, although shielding measures have been taken, in order to ensure the stability of EMC, a waterproof retaining wall 14 is added around the TCON board, which can provide a protective measure for the TCON board and increase the stability of the electrical performance of the full-lamination screen assembly 10. The full-lamination screen assembly 10 and the vehicle mounting bracket 30 are positioned and installed by multiple screws 70, and the waterproof retaining wall 14 around the TCON board and the vehicle mounting bracket 30 are staggered, which improves the anti-interference performance of the TCON board; multiple positioning ribs 42 are arranged in the rear shell 40 for positioning and assembling between the full-lamination screen assembly 10 and the rear shell 40. In order to meet the waterproof requirement of the vehicle-mounted screen, multiple drainage holes 44 are designed at the bottom of the rear shell 40 to avoid the problem of short circuit and damage of the electronic components of the TCON board due to water ingress, avoid the problem of burning the board, and meet the IP5K2 waterproof requirement.
[0046] The waterproof retaining wall 14 can form full or half enclosure for the TCON board to avoid water entering the TCON board. When the waterproof retaining wall 14 forms half enclosure for the TCON board, a gap is formed at the bottom of the waterproof retaining wall 14.
[0047] In this embodiment, the four surrounding edges of the die-cast backlight rear shell 11 are chamfered 111 (such as Figure 4 ), which is very beneficial to the thinning of the vehicle-mounted screen.
[0048] Multiple waterproof ribs 43 are arranged around the rear shell 40, and multiple positioning grooves 13 are arranged around the die-cast backlight rear shell 11. The waterproof ribs 43 and the positioning grooves 13 are arranged one by one, and the waterproof ribs 43 are assembled in the positioning grooves 13.
[0049] The rear end of the vehicle mounting bracket 30 is provided with at least two metal buckles 60 for assembly to the vehicle body; and a wire 50 is arranged on the TCON board for electrical connection with the vehicle body.
[0050] The backlight rear shell 40 is made into a die-casting backlight rear shell 11, and the original bonding mode is replaced by a buckle assembly to avoid the problem of falling gap out of tolerance caused by bonding failure under the condition of ensuring the structural strength of the vehicle-mounted screen, in order to avoid abnormal sound in the use process of the customer, the buckle 41 and the back adhesive (i.e. double-sided adhesive) jointly act, that is, the bonding strength is met, and the abnormal sound problem caused by vibration hard contact is avoided;
