[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-7 The anti-slip frame for a vehicle-mounted backlight source shown in the figure includes a backlight panel 1, a mounting component 2 for mounting the backlight panel 1 is arranged on the outside of the backlight panel 1, a fixing frame 3 for mounting the mounting component 2 is arranged on the outside of the mounting component 2, the mounting component 2 includes a mounting part and a connecting part, the mounting part includes a mounting frame 21, a locking hole for inserting the connecting part is opened on the inner wall of the mounting frame 21, and a shock-absorbing part for reducing the vibration of the backlight panel 1 is arranged on the inner wall of the mounting frame 21.

[0027] Specifically, the bottom end of the fixed frame 3 is fixedly connected with the bottom plate 4, the installation frame 21 is sleeved inside the fixed frame 3, the backlight panel 1 is sleeved inside the installation frame 21, and the top of the installation frame 21 is fixedly connected with a blocking frame 26 for limiting the displacement of the backlight panel 1. The top of the blocking frame 26 is provided with a light-transmitting hole for the backlight panel 1 to transmit light. The connecting part includes a locking block 22, and the inner wall of the fixed frame 3 is provided with a groove. The locking block 22 is connected with the locking hole and the groove through the insertion. The locking block 22 is T-shaped, the locking hole is T-shaped, and the groove is rectangular.

[0028] Furthermore, the backlight panel 1 is an existing large-size vehicle-mounted backlight, such as 12 inches, the size of the mounting frame 21 is 1.2 times the size of the backlight panel 1, the inner wall of the fixing frame 3 and the outer wall of the mounting frame 21 fit each other, so that the mounting frame 21 can be inserted into the fixing frame 3, the thickness of the shock-absorbing member is 1.25 times the gap between the backlight panel 1 and the mounting frame 21, the four corners of the blocking frame 26 are fixedly connected to the four corners of the top of the mounting frame 21 by bolts, and the size of the light-transmitting hole is 0.98 times the size of the backlight panel 1, so that the blocking frame 26 is placed inside the mounting frame 21. The backlight panel 1 acts as a barrier to prevent the backlight panel 1 from sliding out of the mounting frame 21. The outer wall of the blocking frame 26 is flush with the outer wall of the fixed frame 3. The size of the locking hole and the groove together is 1.02 times the size of the locking block 22. By inserting the locking block 22 into the locking hole and the groove, the mounting frame 21 can be connected to the fixed frame 3, so that the mounting frame 21 cannot move vertically. At the same time, the length of the locking block 22 can increase the connection strength between the mounting frame 21 and the fixed frame 3. The four corners of the bottom end of the fixed frame 3 are fixed to the four corners of the top end of the base plate 4 by bolts.

[0029] Specifically, the shock-absorbing component includes a shock-absorbing ring 23, which is sleeved inside the mounting frame 21. An adhesive component for installing the shock-absorbing ring 23 is provided on the side of the shock-absorbing ring 23 close to the mounting frame 21. The adhesive component includes an adhesive layer 24. The outer wall of the adhesive layer 24 is fixedly connected to the inner wall of the mounting frame 21, and the inner wall of the adhesive layer 24 is fixedly connected to the outer wall of the shock-absorbing ring 23. A through groove for removing the connecting component is provided on one side of the shock-absorbing ring 23 and the adhesive layer 24. A pushing block 25 for closing the through groove is inserted and connected inside the through groove. The shape of the through groove and the pushing block 25 are both cross-shaped. A toggle groove for facilitating the movement of the pushing block 25 is provided on the side of the pushing block 25 close to the backlight source panel 1.

[0030] Furthermore, the shock absorbing ring 23 is annular and is arranged around the inner wall of the installation frame 21. The adhesive layer 24 is a double-sided adhesive for fixing the shock absorbing ring 23 inside the installation frame 21. The rectangular size of the middle part of the through groove is 1.1 times the size of the locking hole, so that it is convenient for the locking block 22 to slide out of the through groove. The size of the pushing block 25 is 0.98 times the size of the through groove. The shock absorbing ring 23 and the pushing block 25 are both made of elastic rubber. When the backlight source panel 1 is sleeved in the shock absorbing ring 23, the shock absorbing ring 23 and the pushing block 25 will be squeezed. The elasticity of the shock absorbing ring 23 and the pushing block 25 can reduce the influence of vibration on the backlight source panel 1, and at the same time, the pushing block 25 can be pushed out. The compressed deformation of the squeezing block 25 will generate a thrust on the locking block 22, thereby ensuring the stable installation of the locking block 22. When installing the backlight panel 1, the mounting assembly 2 and the fixed frame 3, the shock-absorbing ring 23 is first fixed and bonded to the inner wall of the mounting frame 21 through the adhesive layer 24, the mounting frame 21 is inserted into the interior of the fixed frame 3, and then the locking block 22 is inserted into the locking hole of the mounting frame 21 and the groove of the fixed frame 3 to complete the locking of the mounting frame 21 and the fixed frame 3. After the squeezing block 25 is inserted into the through groove, the backlight panel 1 is placed in the interior of the shock-absorbing ring 23, and finally the blocking frame 26 is fixedly connected to the mounting frame 21 by bolts.
