Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal display modules, and in particular to a liquid crystal display module that is easy to assemble. Background Art

[0002] A liquid crystal display module is a complete display component that assembles liquid crystal display devices, connectors, integrated circuits, control drive circuits, PCB circuit boards, backlight sources, and structural components. The working principle of a liquid crystal display module is based on the physical properties of liquid crystal. When voltage is applied to the electrodes, the liquid crystal molecules will be oriented or twisted, thereby changing the propagation path or transmittance of light to form images and text.

[0003] Existing liquid crystal display modules require a protective housing to be installed on the liquid crystal display modules during production. Currently, most assembly methods use multiple screws to manually fasten the liquid crystal display module and the protective housing. Due to the large number of screw holes per product during assembly, the manual screwing method is not only inefficient but also prone to screw omissions and under-tightening, resulting in substandard assembly quality of the liquid crystal display module. Therefore, a liquid crystal display module that is easy to assemble is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art and to provide a liquid crystal display module that is easy to assemble.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] Reference Figures 1-8As shown, a liquid crystal display module that is easy to assemble includes an assembly part 1 and a liquid crystal display module body 2, an assembly groove 11 is provided on the assembly part 1, and the size and shape of the assembly groove 11 match the liquid crystal display module body 2, and a plurality of connecting parts 21 are connected to the liquid crystal display module body 2, and a plurality of assembly units 3 are provided on the assembly part 1 for quickly connecting with the plurality of connecting parts 21 on the liquid crystal display module body 2, so that the assembly part 1 and the liquid crystal display module body 2 are quickly assembled, and a plurality of grooves 13 are provided at the bottom of the assembly groove 11, and a detection plate 14 is slidably connected in each of the grooves 13, and a first spring 15 is connected between the bottom surface of the detection plate 14 and the bottom groove wall of the groove 13, and the number of connecting parts 21 on the liquid crystal display module body 2 is the same as the number of assembly units 3 and detection plates 14 on the assembly part 1, and the positions correspond one to one.

[0026] In this embodiment, each of the assembly units 3 includes a connecting seat 31 and a connecting rod 32. The connecting seat 31 is installed on the assembly part 1. The connecting rod 32 is vertically connected to the connecting part 21. A connecting cavity 33 is provided in the connecting seat 31. A plug hole 331 is provided on the top of the connecting seat 31 to communicate with the connecting cavity 33. A lifting plate 34 is slidably connected in the connecting cavity 33. A connecting hole 341 is provided on the lifting plate 34. A moving groove 342 is provided on the lifting plate 34 to communicate with the connecting hole 341. A limiting rod 343 is slidably connected in the moving groove 342. A pair of sliding grooves 345 are provided on the upper and lower groove walls of the moving groove 342. A pair of sliders 346 are connected to the limit rod 343, and the pair of sliders 346 are respectively slidably connected to a pair of slide grooves 345. A second spring 347 is connected to the groove wall of a pair of slide grooves 345 close to the connecting hole 341. The other end of each second spring 347 is connected to the slider 346. A slot 344 is provided on the cavity wall of one side of the connecting cavity 33, and a limit groove 321 is provided on the connecting rod 32. A magnet 322 is embedded on the inner wall of the limit groove 321 of the connecting rod 32. The end of the limit rod 343 close to the connecting hole 341 is made of magnetic material, and the magnet 322 and the limit rod 343 are attracted to each other.

[0027] In this embodiment, a cavity 35 is provided in the connecting seat 31, and a connecting hole 36 is provided on one side wall of the connecting cavity 33 to communicate with the cavity 35. A solenoid valve 361 is provided in the connecting hole 36. The connecting hole 36 in the connecting cavity 33 is higher than the height of the card slot 344 to ensure that the foaming agent sprayed from the cavity 35 is in the space above the lifting plate 34. A first electrical connection piece 371 is embedded in one side wall of the groove 13, and a conductive block 37 is embedded on the side of the detection plate 14 close to the first electrical connection piece 371. A pressure sensor is provided on the wall of the card slot 344. The conductive block 37, the first electrical connection piece 371 and the pressure sensor are electrically connected to the control circuit of the solenoid valve 361 through a wire. When the pressure sensor is pressurized, the circuit controlling the solenoid valve 361 is de-energized, and when it is not pressurized, the circuit controlling the solenoid valve 361 is de-energized. When the assembly 1 and the liquid crystal display module body 2 are not assembled together, although the detection board 14 is in a position so that the conductive block 37 and the first contact piece 371 are in contact, the pressure sensor in the slot 344 is constantly pressed by the limiting rod 343, and the circuit of the solenoid valve 361 is in a de-energized state. When the assembly 1 and the liquid crystal display module body 2 are assembled, the self-weight of the liquid crystal display module body 2 cannot make all the multiple detection boards 14 slide into the groove 13. At this time, the conductive block 37 and the first contact piece 371 still maintain contact.

[0028] In this embodiment, a second electrical connection piece 372 is embedded in the wall of the groove 13 and located directly below the first electrical connection piece 371. An indicator light 38 is installed on the top of the connecting base 31. The second electrical connection piece 372 and the conductive block 37 are electrically connected to the control circuit of the indicator light 38 via a wire. Whether the conductive block 37 and the second electrical connection piece 372 are in contact will control the on and off of the indicator light.

[0029] In this embodiment, a power socket 4 is installed on the assembly 1. The power socket 4 is electrically connected to the control circuit of the solenoid valve 361 and the indicator light 38 through a wire, and is used to connect an external power supply to power the solenoid valve 361 and the indicator light 38.

[0030] In this embodiment, the cavity 35 is filled with a foaming agent, and the foaming agent is a polyurethane foam filler. When the foaming agent material is sprayed from the cavity 35 into the connecting cavity 33 through the connecting hole 36, the foamy polyurethane material will rapidly expand and react with the air or moisture in the substrate it contacts to form foam.

[0031] In this embodiment, a plurality of guide plates 12 are provided on the assembly part 1 around the assembly groove 11. The provision of the plurality of guide plates 12 facilitates the liquid crystal display module body 2 to fall into the assembly groove 11 of the assembly part 1 quickly and accurately during assembly, thereby further improving assembly efficiency.

[0032] The working process and principle of the present invention are as follows:

[0033] When in use, first align the assembly 1 and place it on the assembly station, and connect the external power supply to the power socket 4 to power the circuit on the mounting part 1, and then place the LCD display module body 2 in the assembly slot 11 of the assembly 1. When the LCD display module body 2 falls into the assembly slot 11 under the guidance of the guide plate 12, the connecting rods 32 on the multiple connecting parts 21 will be inserted into the corresponding sockets 331 of the connecting sockets 31. When the connecting rod 32 enters the connecting cavity 33 and is inserted into the connecting hole 341 of the lifting plate 34, the magnetic block 322 in the limiting groove 321 will generate a magnetic attraction force on the limiting rod 343, so that the limiting rod 343 overcomes the resistance of the second spring 347 and slides toward the connecting hole 341, slides into the limiting groove 321 of the connecting rod 32, and at the same time, the limiting rod 3 The other end of 42 leaves the slot 344, releasing the sliding restriction of the lifting plate 34 in the connecting chamber 33. Since the limit rod 342 leaves the slot 344, the pressure sensor is no longer under pressure, and the conductive block 37 and the first contact plate 371 remain in contact at this time, which will connect the circuit where the solenoid valve 361 is located. After the solenoid valve 361 is opened, the foaming agent in the cavity 35 will be sprayed into the connecting chamber 33. The foaming agent material will rapidly expand in the connecting chamber 33 and squeeze the lifting plate 34 downward, driving the connecting rod 32 to descend together, so that the connecting parts 21 at various positions on the liquid crystal display module body 2 are automatically pressed downward, which is equivalent to applying pressure on the liquid crystal display module body 2 to push the liquid crystal display module body 2 to contact the bottom groove wall of the assembly groove 11. Compared with manual screwing, it is efficient and quick.

[0034] When the detection plate 14 at a certain position is completely inserted into the groove 13, it indicates that the LCD module body 2 at that position has been properly assembled. At this time, the conductive block 37 will separate from the first contact piece 371, and the solenoid valve 361 will be de-energized and closed, preventing the foaming agent from continuing to spray. At the same time, the conductive block 37 will contact the second contact piece 372, causing the indicator light 38 on the connector 31 in the area where the LCD module body 2 has been properly assembled to light up.

[0035] When the detection plate 14 has not completely entered the groove 13, it indicates that the liquid crystal display module body 2 at this position has not been assembled in place. The solenoid valve 361 in the connecting seat 31 at this position will remain open to allow the foaming agent to continue to spray out. The increase in the amount of foaming agent is used to give further pressure to the lifting plate 34, pulling the connecting plate 21 to continue to press down the liquid crystal display module body 2 at this position, thereby ensuring that each position of the liquid crystal display module body 2 is assembled in place. The assembler only needs to observe the lighting of the indicator light 38 at each position to know the assembly status of the liquid crystal display module body 2 and the assembly part 1. The entire assembly process is simple and fast, and the assembler does not need to operate the assembly connection points one by one. This not only improves the assembly efficiency, but also avoids the situation where screws are missed or the screws are not tightened during the original screw-tightening assembly, thereby ensuring the assembly quality.

[0036] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
