The manual operation means that a user manually moves the rear shell and the rear shell fixing structure B to finally realize the assembly and disassembly of the rear shell. Automatic means that the rear shell is assembled and disassembled by means of various power sources such as air cylinders, motors, hydraulic cylinders and the like.

Referring to fig. 1-3, in an embodiment, the rear housing fixing structure B includes a movable frame 100, a first engaging portion 200 and a driving mechanism 300.

The moving frame 100 is movably disposed, and the moving frame 100 can reciprocate at least in one direction. The first engaging portion 200 is mounted on the moving frame 100 and can reciprocate with the moving frame 100. The movable frame 100 is installed at the output end of the driving mechanism 300, and the driving mechanism 300 is used for driving the movable frame 100 to move, so that the first engaging portion 200 is engaged with or disengaged from the second engaging portion C disposed on the rear housing.

In this way, since the first engaging portion 200 is mounted on the moving frame 100 and the moving frame 100 can reciprocate in one direction, when the driving mechanism 300 drives the moving frame 100 to move, the first engaging portion 200 can move together with the moving frame 100 to be engaged with or disengaged from the second engaging portion C on the inner surface of the rear housing, thereby realizing the mounting and dismounting of the rear housing.

The function of the drive mechanism 300 may be performed manually or automatically. When it is in an automatic manner, the movement of the moving frame 100 may be driven by means of a motor, a lead screw, or the like, for example. When it is manual, it can be realized by using the following exemplary structure.

As an example, referring to fig. 2 and fig. 4-5 in combination, the driving mechanism 300 includes an adjusting member 310 and a fixing frame 320, the fixing frame 320 is fixedly disposed, the fixing frame 320 is provided with an internal threaded hole, the outer periphery of the adjusting member 310 is provided with an external thread, one end of the adjusting member 310 is fixedly connected to the movable frame 100, and the other end of the adjusting member passes through the threaded hole.

At this time, the adjusting member 310 can move in the fixed frame 320 by controlling the forward and backward rotation of the adjusting member 310, so as to drive the movable frame 100 to reciprocate.

In some embodiments, the adjusting member 310 may be implemented by combining a screw 311 and a stud 312, wherein a screw cap of the screw 311 may be connected to the movable frame 100, and a screw portion of the screw 311 may pass through the fixed frame 320 to be screwed with the stud 312 having a threaded hole, and the adjusting member 310 may be adjusted by adjusting the stud 312.

Further, for convenience of adjustment, a specially shaped slot 3121, such as a regular hexagonal slot 3121, may be provided at the end of the stud 312, and at this time, the stud 312 may be adjusted by using a wrench or the like.

Of course, in some embodiments, the adjusting member 310 may also be directly connected to some mechanism capable of outputting rotational movement, and the automatic adjustment of the adjusting member 310 can be realized by controlling the actions of the mechanism.

On the other hand, the movable frame 100 may be a single body, and in this case, the first engaging portion 200 and the second engaging portion C can be engaged or disengaged by driving the movable frame 100 through the driving mechanism 300, but in most cases, the movable frame 100 generally includes two movable bodies in order to ensure the reliability of the rear case installation.

Referring to fig. 1 to 3, in an embodiment, the movable frame 100 includes a first movable frame 110 and a second movable frame 120 connected to the first movable frame 110, the driving mechanism 300 can act on the first movable frame 110 to enable the first movable frame 110 to output a reciprocating motion in a vertical direction, and the first movable frame 110 can act on the second movable frame 120 to enable the second movable frame 120 to output a reciprocating motion in a horizontal direction.

Therefore, the first engaging portion 200 is respectively mounted on the first moving frame 110 and the second moving frame 120, so that the first engaging portion 200 is engaged with the second engaging portion C in the vertical direction or the horizontal direction, and the mounting reliability of the rear case is greatly improved.

It is understood that the driving mechanism 300 may be disposed at an end of the first moving frame 110, or disposed at an end of the second moving frame 120, and the description will be given by taking the case where the driving mechanism is disposed at an end of the first moving frame 110 as an example.

Referring to fig. 2-3, the driving mechanism 300 is disposed below the first moving frame 110, and when the driving mechanism 300 moves upward, the first moving frame 110 is driven to move upward, and then the first moving frame 110 drives the second moving frame 120 to move rightward, so that the first engaging portion 200 is engaged with the second engaging portion C.

A guiding transition mechanism 400 is further disposed at the junction of the first moving frame 110 and the second moving frame 120, and the guiding transition mechanism 400 is used for guiding the second moving frame 120 to move in the horizontal direction.

With continued reference to fig. 2-3, in one embodiment, the guiding transition mechanism 400 includes a first transition block 410 disposed on the first movable frame 110 and a second transition block 420 disposed on the second movable frame 120, and the mating surfaces of the first transition block 410 and the second transition block 420 are configured as inclined surfaces.

Thus, when the first moving frame 110 moves upward, it applies a rightward force to the second moving frame 120, so that the second moving frame 120 moves rightward.

Referring to fig. 6, in order to ensure the stability of the fit between the first transition block 410 and the second transition block 420, one of the first transition block 410 and the second transition block 420 is provided with a limiting guide slot 411, and the other one is provided with a protruding rail 421 capable of moving in the limiting guide slot 411.

Of course, in some embodiments, the first transition block 410 and the second transition block 420 may not be provided, and the first moving frame 110 and the second moving frame 120 may be adaptively provided, for example, the limiting guide slot 411 and the convex rail 421 are directly provided on the first moving frame 110 and the second moving frame 120.

At this point, the first movable frame 110 and the second movable frame 120 can move by the driving action of the driving mechanism 300, and finally, the first engaging portion 200 and the second engaging portion C are engaged. It is understood that the mobile frame 100 may further include more movable individuals, for example, the mobile frame 100 may further include a third mobile frame engaged with the second mobile frame 120 to further improve the installation reliability of the rear case.

Referring to fig. 2-3, the first engaging portion 200 has a locking post 210 extending along the moving direction of the moving rack 100, and the second engaging portion C has a receiving slot capable of receiving the locking post 210, when the mobile rack is installed, the rear housing is first placed, so that the second engaging portion C on the rear housing is located on the moving stroke of the locking post 210, and when the driving mechanism 300 drives the moving rack 100 to move, the locking post 210 is locked into the receiving slot, and at this time, the first engaging portion 200 is locked with the second engaging portion C. When the housing needs to be disassembled, the driving mechanism 300 is controlled to move the movable frame 100 in the reverse direction.

Referring to fig. 2-3, in some embodiments, the backlight module further includes an elastic mechanism 500, one end of the elastic mechanism 500 is connected to the movable frame 100, and the other end is fixedly mounted on the backlight module a.

Specifically, the elastic mechanism 500 includes a spring 510, the spring 510 is in a compressed state before the first engaging portion 200 is engaged with the second engaging portion C, and when the moving frame 100 moves, for example, when the first moving frame 110 moves upward, the spring 510 may provide a certain elastic restoring force to facilitate the upward movement of the first moving frame 110. After the first engaging portion 200 is engaged with the second engaging portion C, the spring 510 is in a natural state, which can effectively prevent the first engaging portion 200 from being separated from the second engaging portion C when the driving mechanism 300 fails, and maintain the stability after the first engaging portion 200 is engaged with the second engaging portion C.

The elastic mechanism 500 may be provided in a plurality of numbers, and arranged on the movable frame 100 at regular intervals.

Referring to fig. 2-3, in some embodiments, a limiting member 600 may be further included, the movable frame 100 is provided with a through groove D having a predetermined length along the moving direction, and the limiting member 600 is disposed in the through groove D for limiting the moving stroke of the movable frame 100.

The length of the through groove D matches the depth of the receiving groove of the second engaging portion C, and at this time, when the movable frame 100 moves from one end of the through groove D to the other end, the relationship between the first engaging portion 200 and the second engaging portion C is just switched from the separated state to the engaged state or just switched from the engaged state to the separated state.

The through groove D and the limiting member 600 can effectively prevent the movable frame 100 from moving excessively to damage the first engaging portion 200 and/or the second engaging portion C, and can effectively prolong the service life of the rear housing fixing structure B, the rear housing and even the entire display device.

The through slots D and the stoppers 600 may also be provided in multiple groups, and are uniformly spaced on the movable frame 100.
