The working principle of the liquid crystal display module is based on the physical properties of liquid crystals. When a voltage is applied to the electrodes, the liquid crystal molecules will be aligned or twisted, thereby changing the light propagation path or light transmittance to form images and texts.

[0003] When the existing liquid crystal display modules are produced, a protective shell needs to be installed on the liquid crystal display module. At present, most of the assembly methods use multiple screws manually to fasten the liquid crystal display module and the protective shell. Since the number of screw holes for each product is relatively large during assembly, the manual method of screwing the screws not only has low efficiency, but also easily leads to the situation of missing screws and loose screws, resulting in the unqualified assembly quality of the liquid crystal display module. Therefore, a liquid crystal display module that is convenient for assembly is proposed. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] Refer to Figures 1-8As shown in the figure, a liquid crystal display module that is convenient for assembly includes an assembly part 1 and a liquid crystal display module body 2. An assembly groove 11 is formed on the assembly part 1, and the size and shape of the assembly groove 11 match those of the liquid crystal display module body 2. A plurality of connecting parts 21 are connected to the liquid crystal display module body 2. A plurality of assembly units 3 are arranged on the assembly part 1 for quickly connecting with the plurality of connecting parts 21 on the liquid crystal display module body 2, so as to complete the quick assembly between the assembly part 1 and the liquid crystal display module body 2. A plurality of grooves 13 are formed at the bottom of the assembly groove 11. A detection plate 14 is slidably connected in each groove 13. A first spring 15 is connected between the bottom surface of the detection plate 14 and the bottom groove wall of the groove 13. The number of the connecting parts 21 on the liquid crystal display module body 2 is the same as the number of the assembly units 3 and the detection plates 14 on the assembly part 1, and their positions correspond one by one.

[0025] In this embodiment, each assembly unit 3 includes a connection seat 31 and a connection insertion rod 32. The connection seat 31 is installed on the assembly part 1. The connection insertion rod 32 is vertically connected to the connecting part 21. A connection cavity 33 is formed in the connection seat 31. A jack 331 is formed at the top of the connection seat 31 and is communicated with the connection cavity 33. A lifting plate 34 is slidably connected in the connection cavity 33. A connection hole 341 is formed in the lifting plate 34. A moving groove 342 is formed in the lifting plate 34 and is communicated with the connection hole 341. A limiting rod 343 is slidably connected in the moving groove 342. A pair of sliding grooves 345 are formed on the upper and lower groove walls of the moving groove 342. A pair of sliding blocks 346 are connected to the limiting rod 343. The pair of sliding blocks 346 are respectively slidably connected with the pair of sliding grooves 345. A pair of second springs 347 are connected to the side groove walls of the pair of sliding grooves 345 close to the connection hole 341. The other end of each second spring 347 is connected to the sliding block 346. A clamping groove 344 is formed on one side cavity wall of the connection cavity 33. A limiting groove 321 is formed on the connection insertion rod 32. A magnet 322 is embedded on the inner wall of the limiting groove 321 of the connection insertion rod 32. One end of the limiting rod 343 close to the connection hole 341 is made of a magnetic material, and the magnet 322 and the limiting rod 343 attract each other magnetically.

[0026] In this embodiment, a cavity 35 is formed in the connecting seat 31. A communication hole 36 is formed in one side wall of the connecting cavity 33 to communicate with the cavity 35. An electromagnetic valve 361 is arranged in the communication hole 36. The connection hole 36 in the connecting cavity 33 is higher than the height of the clamping groove 344, ensuring that the foaming agent sprayed from the cavity 35 is in the upper space of the lifting plate 34. A first electrical connection piece 371 is embedded in one side wall of the groove 13. A conductive block 37 is embedded in the side of the detection plate 14 close to the first electrical connection piece 371. A pressure sensor is arranged on the wall of the clamping groove 344. The conductive block 37, the first electrical connection piece 371 and the pressure sensor are electrically connected to the control circuit of the electromagnetic valve 361 through wires. When the pressure sensor is pressed, the circuit of the electromagnetic valve 361 is powered off, and when not pressed, the circuit of the electromagnetic valve 361 is powered on. When the assembly 1 and the liquid crystal display module body 2 are not assembled together, although the position of the detection plate 14 makes the conductive block 37 and the first electrical connection piece 371 in contact, the pressure sensor in the clamping groove 344 is always pressed by the limiting rod 343, and the circuit of the electromagnetic valve 361 is in a powered-off 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 detection plates 14 slide into the groove 13. At this time, the conductive block 37 and the first electrical connection piece 371 still remain in contact.

[0027] In this embodiment, a second electrical connection piece 372 is embedded in the groove wall of the groove 13 and at the position directly below the first electrical connection piece 371. An indicator light 38 is installed on the top of the connecting seat 31. The second electrical connection piece 372 and the conductive block 37 are electrically connected to the control circuit of the indicator light 38 through wires. Whether the conductive block 37 is in contact with the second electrical connection piece 372 will control the lighting and extinguishing of the indicator light.

[0028] In this embodiment, a power connection seat 4 is installed on the assembly 1. The power connection seat 4 is electrically connected to the control circuits of the electromagnetic valve 361 and the indicator light 38 through wires, and is used to connect an external power supply to supply power to the electromagnetic valve 361 and the indicator light 38.

[0029] In this embodiment, the cavity 35 is filled with a foaming agent, and the foaming agent adopts a polyurethane foam caulking agent. When the foaming agent material is sprayed from the cavity 35 into the connecting cavity 33 through the communication hole 36, the foamed polyurethane material will rapidly expand and react with the moisture in the air or the matrix it contacts to form a foam.

[0030] In this embodiment, a plurality of guiding plates 12 are arranged around the assembly groove 11 on the assembly 1. The arrangement of the plurality of guiding plates 12 facilitates the liquid crystal display module body 2 to quickly and accurately fall into the assembly groove 11 of the assembly 1 during assembly, further improving the assembly efficiency.

[0031] The working process and principle of the present invention are as follows: During use, first place the assembly 1 in alignment on the assembly station, connect an external power supply to the power socket 4 to supply power to the circuit on the mounting member 1, and then place the liquid crystal display module body 2 in the assembly groove 11 of the assembly 1. After the liquid crystal display module body 2 falls into the assembly groove 11 under the guidance of the guide plate 12, the connecting rods 32 on the plurality of connecting members 21 will just insert into the jacks 331 of the corresponding connecting seats 31. When the connecting rod 32 enters the connecting cavity 33 and inserts into the connecting hole 341 of the lifting plate 34, the magnet 322 in the limiting groove 321 will generate a magnetic attraction force on the limiting rod 343, causing the limiting rod 343 to slide towards the connecting hole 341 against the resistance of the second spring 347 and slide into the limiting groove 321 of the connecting rod 32. At the same time, the other end of the limiting rod 342 will leave the clamping groove 344, releasing the sliding restriction of the lifting plate 34 in the connecting cavity 33. Since the limiting rod 342 leaves the clamping groove 344, the pressure sensor is no longer under pressure, and at this time the conductive block 37 and the first electrical connection piece 371 remain in contact, which will turn on 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 cavity 33. The foaming agent material will quickly expand in the connecting cavity 33 and squeeze the lifting plate 34 to slide down, driving the connecting rod 32 to descend together, realizing the automatic downward pressing of the connecting members 21 at various positions on the liquid crystal display module body 2, which is equivalent to applying pressure to the liquid crystal display module body 2 to push the liquid crystal display module body 2 into contact with the bottom wall of the assembly groove 11, which is more efficient and faster than manually screwing in screws.

[0032] When the detection plate 14 at a certain position completely enters the groove 13, it indicates that the liquid crystal display module body 2 at this position has been assembled in place. At this time, the conductive block 37 will separate from the first electrical connection piece 371, the solenoid valve 361 will be powered off and closed to prevent the foaming agent from continuing to spray. At the same time, the conductive block 37 will contact the second electrical connection piece 372, causing the indicator light 38 on the connecting seat 31 in the area where the liquid crystal display module body 2 has been assembled in place to light up.

[0033] When the detection plate 14 does not completely enter 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, using the increase in the amount of foaming agent to apply further pressure to the lifting plate 34 and pull the connecting plate 21 to press down the liquid crystal display module body 2 at this position, so as to ensure that the liquid crystal display module body 2 is assembled in place at each position. The assembly personnel only need to observe the lighting conditions of the indicator lights 38 at each position to know the assembly situation of the liquid crystal display module body 2 and the assembly 1. Moreover, the entire assembly process is simple and fast, and there is no need for the assembly personnel to operate each assembly connection point one by one, which not only improves the assembly efficiency but also avoids the situations of missing screws and loose screws during the original screw assembly, ensuring the assembly quality.

[0034] As is known by common technical knowledge, the present invention can be implemented by other embodiments that do not depart from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
