Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings.

This specific embodiment is only an explanation of the present invention, and it does not limit the present invention. Those skilled in the art can make modifications without creative contribution to the present embodiment as required after reading this specification, but as long as the rights of the present invention are used All claims are protected by patent law.

Embodiment: A TV module backplane structure and assembly method, as shown in Figures 1 to 3, includes a rear shell 2, a main board 3 and a power supply board arranged on the TV backplane 1, and the power supply board is integrated on the main board. 3 , the main board 3 is arranged inside the rear shell 2 , and the rear shell 2 is provided with a terminal insert groove 22 adapted to the peripheral terminals 21 on the main board 3 .

The TV backplane 1 is a metal backplane, which is formed by stamping, and can be made of electro-galvanized sheet, galvanized sheet, aluminum alloy sheet and other materials, and can be used with spraying, paint or oxidation to achieve a beautiful appearance, or PCM color steel plate can be used. .

The TV backplane 1 is formed by punching to form the reinforcing bosses 12 , so that the structural strength of the panel surface portion of the TV backplane 1 is higher, so there is no need to add additional reinforcing ribs or support by a fixing device, which saves costs.

The rear shell 2 is an injection molded part, which is integrally formed and has the advantage of being light. The power board is integrated on the main board 3, which changes the separate design of the power board and the main control board in the traditional TV, saves the manufacturing cost, saves electricity, and is easy to maintain.

The upper end of the rear shell 2 is provided with a heat dissipation port 25 . The heat dissipation ports 25 are disposed on both sides of the terminal insert groove 22 , and the heat dissipation ports 25 are recessed inwards and open on the sides to prevent dust from falling in while ventilating.

The outer side of the terminal insert groove 22 is provided with an insert groove cover plate 24 which can be detachably connected. The slotted cover 24 is an auxiliary part of the rear casing 2 of the TV structure. When the TV is not used or transported for a long time, the slotted cover 24 is installed on the outer side of the terminal slot 22 to play a protective role.

The rear shell 2 is provided with a cable management slot 26 . The cable management slot 26 is connected to an expansion interface 27 on the main board 3 , and the expansion interface 27 includes a USB interface, a DP interface, and the like.

As shown in FIG. 2 , FIG. 5 and FIG. 7 , the terminal insert groove 22 is provided with a peripheral insert 23 for connecting the peripheral terminal 21 . The connection part 233 is provided with an output part 234 on the upper end of the peripheral insert 23 . The peripheral inserts 23 are connected with the terminal inserts 22 in a snap-fit connection, the side walls of the terminal inserts 22 are provided with grooves 221 , and the peripheral inserts 23 are provided with protrusions adapted to the grooves 221 . Block 231.

Specifically, the terminal inserting groove 22 is opened at the upper end of the rear shell 2, the groove 221 and the convex block 231 are both arc-shaped, and the inner wall and the outer wall of the terminal inserting groove 22 are provided with a clamping groove 222, The peripheral insert 23 is provided with a clamping block 232 adapted to the clamping slot 222 .

When developing TVs in different countries or regions, the peripheral terminals 21 on the main board 3 are usually different, so the TV manufacturer needs to repeat the mold opening when developing the TV module backplane and the structural rear shell 2, so the manufacturing cost is high. The peripheral inserts 23 of the present invention are adapted to the peripheral terminals 21. Even if the peripheral terminals 21 are changed, only the peripheral inserts 23 need to be replaced, and the manufacturing cost of the peripheral inserts 23 is very low, so saving a lot of cost.

As shown in FIG. 3 and FIG. 4 , the mainboard 3 and the rear case 2 are both screwed to the TV backplane 1 . The mainboard 3 includes four fixing screws 31 arranged on four corners of the mainboard 3 respectively, and a positioning screw 32 arranged in the middle of the mainboard 3 . The TV back panel 1 is provided with threaded bosses 11 adapted to the fixing screws 31 and the positioning screws 32 .

The positioning screw 32 in the middle of the main board 3 is set at a certain distance away from the center of the main board 3 , so as to prevent the main board 3 and the TV backplane 1 from being reversely installed during assembly.

Since the power board is integrated on the main board 3, the temperature of the main board 3 during operation is higher than that of the traditional split main control board and the power board. Therefore, both the reinforcing bosses 12 and the threaded bosses 11 protrude toward the main board 3, the mainboard 3 is threadedly connected to the threaded bosses 11, and the TV back plate 1 forms a depression between the reinforcing bosses 12 and the threaded bosses 11, which is helpful for The air is circulated, which is beneficial to the heat dissipation of the motherboard 3 .

As shown in FIG. 3 , the TV back panel 1 is further provided with an AV bracket 4 which is shielded from the outer side of the peripheral terminal 21 , and the AV bracket 4 is arranged between the main board 3 and the rear case 2 .

The AV bracket 4 is L-shaped, one side of the AV bracket 4L is screwed to the TV backplane 1, and the other side of the AV bracket 4L is blocked from the peripheral terminal 21, which plays a role of fixing and supporting.

Embodiments of the present invention also provide an LCD TV, which includes the above-mentioned TV module backplane structure; the details are as described above.

To sum up, in the present invention, by setting the peripheral inserts 23, when developing TVs in different countries or regions, only the peripheral inserts 23 need to be replaced, which saves the repeated mold opening of the module backplane and the structural back shell 2. cost; at the same time, the power board is integrated on the main board 3, which saves the cost.

It should be understood that the application of the present invention is not limited to the above examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above descriptions, and all these improvements and transformations should belong to the protection scope of the appended claims of the present invention.
