[0028] 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. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 7 As shown, the present application provides an LED box assembly including: a box 10, a power box 20 and a locking structure 30. The power box 20 is detachably mounted on the rear side of the box 10. The locking structure 30 is arranged on the box 10, and the locking structure 30 includes a mounting plate 31, a locking plate 32 and a positioning member 33. The mounting plate 31 is arranged on the box 10 and forms a mounting interlayer 34 with the box 10. The locking plate 32 is movably arranged in the mounting interlayer 34 and has an avoidance position and a locking position. The positioning member 33 is arranged between the mounting plate 31 and the locking plate 32. When the locking plate 32 is located in the mounting interlayer 34 to be in the avoidance position, the power box 20 can be removed from the rear side of the box 10. When the locking plate 32 extends out of the mounting interlayer 34 and is locked with the power box 20 to be in the locking position, the power box 20 is locked on the rear side of the box 10. The locking plate 32 can be kept in the avoidance position or the locking position by the positioning member 33 .

[0030] Applying the technical solution of this embodiment, the LED box assembly includes: a box 10, a power box 20 and a locking structure 30. When the locking plate 32 is located in the installation interlayer 34 to be in the avoidance position, the power box 20 can be removed from the rear side of the box 10. When the locking plate 32 extends out of the installation interlayer 34 and is locked with the power box 20 to be in the locking position, the power box 20 is locked on the rear side of the box 10. In this way, the avoidance position and the locking position of the locking plate 32 make it quick and easy to remove and install the power box 20 from the box 10, and can be operated with one hand, which is convenient to operate. In addition, the locking plate 32 can be kept in the avoidance position or the locking position by the positioning member 33. In this way, through the positioning of the positioning member 33, the locking plate 32 can be reliably kept in the avoidance position or the locking position, reducing the possibility that the locking plate 32 is easily loosened when subjected to vibration. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the screws are easily loosened, making the fixation of the power box unreliable.

[0031] like Figures 1 to 7As shown, the positioning member 33 includes a first positioning hole 331, a second positioning hole 332 and a positioning column 333. The second positioning hole 332 is closer to the power box 20 than the first positioning hole 331. The first positioning hole 331 and the second positioning hole 332 are both arranged on the mounting plate 31. The positioning column 333 is arranged on the locking plate 32. When the positioning column 333 is positioned and matched with the first positioning hole 331, the locking plate 32 is kept in the avoidance position. When the positioning column 333 is positioned and matched with the second positioning hole 332, the locking plate 32 is kept in the locking position.

[0032] like Figures 1 to 7 As shown, in the process of the locking plate 32 moving from the locking position to the avoidance position, when the thrust of the locking plate 32 by the operator is greater than the positioning force between the positioning column 333 and the second positioning hole 332, the positioning column 333 slides out of the second positioning hole 332 until the positioning column 333 slides into the first positioning hole 331 and is positioned and matched with the first positioning hole 331. At this time, since the positioning column 333 is blocked by the hole wall of the first positioning hole 331, that is, the thrust of pushing the locking plate 32 is less than the positioning force between the positioning column 333 and the first positioning hole 331, the operator stops pushing the locking plate 32, and since the positioning force between the positioning column 333 and the first positioning hole 331 is larger, the locking plate 32 is kept in the avoidance position, and the power box 20 can be quickly and easily removed from the rear side of the box body 10. Conversely, the locking plate 32 is kept in the locking position, and the power box 20 can be reliably locked on the rear side of the box body 10. In this way, the positioning column 333 and the first positioning hole 331 and the second positioning hole 332 are respectively positioned and matched with each other, and the structure is simple, the positioning is reliable, and the processing is easy.

[0033] Of course, in an embodiment not shown in the figures, the first positioning hole and the second positioning hole are both arranged on the locking plate, and the positioning column is arranged on the mounting plate.

[0034] like Figures 1 to 7 As shown, a positioning hemisphere 334 is disposed at one end of the positioning column 333 facing the first positioning hole 331 or the second positioning hole 332. Thus, when the thrust of the operator pushing the locking plate 32 is greater than the positioning force between the positioning column 333 and the first positioning hole 331 or the second positioning hole 332, the positioning hemisphere 334 facilitates the positioning column 333 to slide out of or into the first positioning hole 331 or the second positioning hole 332.

[0035] like Figures 1 to 7As shown, the first positioning hole 331 and the second positioning hole 332 are provided with a chamfered portion 335 at one end facing the positioning post 333. When the thrust of the operator pushing the locking plate 32 is greater than the positioning force between the positioning post 333 and the first positioning hole 331 or the second positioning hole 332, the chamfered portion 335 and the positioning hemisphere 334 play a guiding role, making it easier for the positioning post 333 to slide out of or into the first positioning hole 331 or the second positioning hole 332.

[0036] Of course, in an embodiment not shown in the figure, a rounded corner portion is provided at one end of the first positioning hole or the second positioning hole facing the positioning column.

[0037] like Figures 1 to 7 As shown, the positioning column 333 is a telescopic column, and the telescopic direction of the telescopic column is perpendicular to the moving direction of the locking plate 32. When the locking plate 32 switches between the locking position and the avoidance position, the telescopic column can automatically retract to avoid the hole wall of the first positioning hole 331 and the hole wall of the second positioning hole 332. When the positioning column 333 moves to the first positioning hole 331, the telescopic column can automatically extend, and the positioning column 333 is positioned and matched with the first positioning hole 331. When the positioning column 333 moves to the second positioning hole 332, the telescopic column can automatically extend, and the positioning column 333 is positioned and matched with the second positioning hole 332. Specifically, the telescopic column includes a spring and a marble that abuts and cooperates with the spring. The marble is positioned and matched with the first positioning hole 331 or the second positioning hole 332.

[0038] like Figures 1 to 7 As shown, in order to facilitate the installation of the locking plate 32 on the front side of the box body 10, a mounting groove is provided on the front side of the box body 10, and the mounting groove extends along the moving direction of the locking plate 32. The end of the mounting groove away from the power box 20 is a closed end, and the end of the mounting groove facing the power box 20 is an open end. An installation interlayer 34 is formed between the mounting groove and the mounting plate 31, and the locking plate 32 can be located in the mounting groove or extend out of the mounting groove from the open end.

[0039] like Figures 1 to 7 As shown, the locking structure 30 also includes an elastic member 36 disposed between the closed end and the locking plate 32. The elastic member 36 applies an elastic force to the locking plate 32 so that the locking plate 32 is in an avoidance position or a locking position. When the locking plate 32 is in the avoidance position, the power box can be removed from the box body, the elastic member 36 is compressed, and the positioning column 333 is positioned and matched with the first positioning hole 331. When the power box is to be locked, the locking plate 32 is moved, and the locking plate 32 easily slides out of the first positioning hole 331 and slides into the second positioning hole 332 under the action of the spring. The power box is locked by the locking plate 32. Under the action of the elastic force of the elastic member 36, the locking plate 32 is not easy to rebound and unlock, which plays a safety role. The elastic member 36 is preferably a compression spring.

[0040] like Figures 1 to 7 As shown, in order to facilitate pushing the locking plate 32, the locking structure 30 further includes an operating member 35 disposed on the locking plate 32, the operating member 35 penetrates from the front side of the box body 10 to the rear side of the box body 10, and the box body 10 is provided with an escape hole 11 for escaping the operating member 35, and the operating member 35 drives the locking plate 32 to switch between the escape position and the locking position. In this way, at the rear side of the box body 10, it is convenient to directly push the locking plate 32 with one hand.

[0041] like Figures 1 to 7 As shown, in order to further reliably lock the power box 20 on the box body, the power box 20 includes a box body 21 and an outer flange 22 arranged at the edge of the box body 21, and the locking plate 32 is locked with the outer flange 22 to put the locking plate 32 in a locked position.

[0042] The present application also provides an LED display device, which includes an LED box assembly and a display module arranged on the front side of the LED box assembly, and the LED box assembly is the above-mentioned LED box assembly. Since the above-mentioned LED box assembly can solve the problem in the related art that the screws are easy to loosen, making the fixing of the power box unreliable, the LED display device having the LED box assembly can solve the same technical problem.
