[0040] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0041] Below, refer to Figures 1-7 Describe the panel assembly 100 according to the embodiments of the first aspect of the present utility model.

[0042] As Figures 1-3 shown, the panel assembly 100 according to the embodiments of the first aspect of the present utility model includes: a panel 10 and a display box 20.

[0043] Specifically, the display box 20 is snap-connected to the panel 10. For example, a first clamping portion may be formed on the panel 10, and a second clamping portion may be formed on the display box 20. The first clamping portion and the second clamping portion may be snap-connected to each other to snap-connect the display box 20 to the panel 10. Among them, the first clamping portion and the second clamping portion include but are not limited to snap hooks, snap holes, clamping protrusions, clamping grooves, etc.

[0044] For example, a plurality of snap fasteners 12 are provided on the panel 10. The plurality of snap fasteners 12 are arranged at intervals along the circumference of the display box 20. The plurality of snap fasteners 12 can hold the peripheral edge of the display box 20, and the display box 20 is snap-connected to the panel 10 through the plurality of snap fasteners 12.

[0045] Among them, a first limiting portion 11 is provided on the panel 10, and a second limiting portion 21 is provided on the display box 20. The first limiting portion 11 and the second limiting portion 21 are in limiting cooperation to limit the display box 20 from moving relative to the panel 10 in the left-right direction. Thus, through the limiting cooperation of the first limiting portion 11 and the second limiting portion 21, the display box 20 and the panel 10 can be relatively fixed. In this way, when the display box 20 is under the action of an external force, for example, under the pulling force of the connecting wire of the display box 20, the display box 20 can be restricted from moving left and right relative to the panel 10, effectively avoiding the snap disconnection between the display box 20 and the panel 10, and avoiding safety problems when the display box 20 is connected to other components.

[0046] It can be understood that the limiting structures of the first limiting portion 11 and the second limiting portion 21 include but are not limited to limiting posts 111, limiting holes 211, limiting ribs, limiting grooves, limiting hooks, limiting blocks, etc. For example, limiting blocks may be provided on the panel 10, and the limiting blocks are arranged on the left and right sides of the display box 20, and the left and right side surfaces of the display box 20 can abut against the limiting blocks.

[0047] According to the panel assembly 100 of the embodiment of the present invention, by respectively providing the first limiting portion 11 and the second limiting portion 21 on the panel 10 and the display box 20, and through the limiting cooperation of the first limiting portion 11 and the second limiting portion 21, the display box 20 is limited in the left-right direction. In this way, when the display box 20 is subjected to a force in the left-right direction, the movement of the display box 20 can be restricted, thereby avoiding the disconnection of the display box 20, improving the connection reliability between the display box 20 and the panel 10, and avoiding safety regulations problems caused by the disconnection of the display box 20.

[0048] In an embodiment of the present invention, the number of the first limiting portions 11 may be one or a plurality arranged at intervals, the number of the second limiting portions 21 may be one or a plurality arranged at intervals, and the first limiting portions 11 and the second limiting portions 21 correspond to each other one by one and cooperate for limiting.

[0049] In an embodiment of the present invention, asFigure 2 and Figure 3 As shown in Figure 3 , one of the first limiting portion 11 and the second limiting portion 21 is provided with a limiting hole 211 and the other is provided with a limiting post 111. The limiting post 111 extends in the front-rear direction and is fitted into the limiting hole 211. That is to say, when the first limiting portion 11 is provided with the limiting hole 211, the second limiting portion 21 can be provided with the limiting post 111. When the first limiting portion 11 is provided with the limiting post 111, the second limiting portion 21 is provided with the limiting hole 211. The limiting post 111 extends in the front-rear direction, the limiting hole 211 extends in the front-rear direction, and the limiting post 111 is arranged in the limiting hole 211.

[0050] In this embodiment, by sleeving the limiting post 111 extending in the front-rear direction into the limiting hole 211, not only can the position of the display box 20 in the left-right direction be limited, but also the position of the display box 20 in the up-down direction can be limited, that is, the displacement of the display box 20 in the plane perpendicular to the front-rear direction can be realized. Thus, the limiting effect on the display box 20 can be further improved, and the reliability of the fixation between the display box 20 and the panel 10 can be improved. In addition, by the cooperation of the limiting post 111 and the limiting hole 211, the limiting structure can be simplified and the processing is convenient.

[0051] In an embodiment of the present utility model, as Figure 3 shown, the first limiting portion 11 is provided with a limiting post 111. The limiting post 111 penetrates through the limiting hole 211, and the end of the limiting post 111 facing away from the panel 10 passes through the limiting hole 211 and extends out of the limiting hole 211. For example, the display box 20 is fixed to the rear side of the panel 10. The rear side surface of the panel 10 is provided with a limiting post 111 protruding rearward. The limiting post 111 penetrates through the limiting hole 211 in the front-to-back direction, and the rear end of the limiting post 111 extends beyond the rear end edge of the limiting hole 211. In this way, when the display box 20 is pulled backward under the action of an external force, the limiting post 111 can still cooperate in the limiting hole 211. Thus, the limiting effect can be ensured, and the risk of the display box 20 being disengaged under the action of an external force can be further reduced.

[0052] In an embodiment of the present utility model, as Figure 2 and Figure 3 shown, in the front-rear direction, the length of the part of one end of the limiting post 111 extending out of the limiting hole 211 is 1 mm - 2 mm. For example, the length of the part of the end of the limiting post 111 facing away from the panel 10 extending out of the limiting hole 211 can be 1 mm, 1.5 mm or 2 mm.

[0053] It should be noted that when the end of the limit post 111 facing away from the panel 10 does not protrude from the limit hole 211, or when the distance protruding from the limit hole 211 is too small, if the display box 20 is pulled in the front-rear direction under the action of an external force, the limit post 111 is easily pulled out of the limit hole 211, thus losing the limiting effect on the display box 20. When the distance that the end of the limit post 111 facing away from the panel 10 protrudes from the limit hole 211 is too long, on the one hand, it is not convenient for the processing of the limit post 111, increasing the processing difficulty. On the other hand, the limit post 111 is prone to interference with other components.

[0054] In this embodiment, by setting the length of the part of the limit post 111 protruding from the limit hole 211 between 1 mm and 2 mm, the mating length between the limit post 111 and the limit hole 211 can be increased, the limiting mating effect between the limit post 111 and the limit hole 211 can be improved, and it is also convenient for the processing and manufacturing of the limit post 111, avoiding interference between the limit post 111 and other components.

[0055] In an embodiment of the present utility model, as Figure 3 shown, the limit post 111 has a material-reducing hole 1111, and the material-reducing hole 1111 extends in the front-rear direction and penetrates the end face of the end of the limit post 111 facing away from the panel 10. In this way, not only can the material usage be reduced, but also the formation of injection molding defects at the position of the panel 10 connected to the limit post 111 during injection molding can be avoided, improving the molding quality of the panel 10. For example, the limit post 111 is a hollow cylindrical shape extending in the front-rear direction, and the material-reducing hole 1111 is defined inside.

[0056] In an embodiment of the present utility model, as Figure 3 shown, the limit post 111 and the limit hole 211 are in clearance fit. For example, the clearance between the limit post 111 and the peripheral wall of the limit hole 211 can be greater than 0 and less than or equal to 1 mm. Specifically, the clearance between the limit post 111 and the limit hole 211 can be 0.2 mm, 0.4 mm, 0.5 mm, 0.8 mm, 0.9 mm, etc. In this embodiment, by making the limit post 111 and the limit hole 211 in clearance fit, it is convenient for the limit post 111 to be inserted into the limit hole 211, improving the assembly efficiency.

[0057] In an embodiment of the present utility model, referring to Figure 3 shown, the length of the limit post 111 in the front-rear direction can be 8 mm - 15 mm. For example, the length of the limit post 111 in the front-rear direction can be 10 mm, 12 mm, 14 mm, etc.

[0058] In an embodiment of the present utility model, referring to Figure 3 shown, the cross-section of the limit post 111 can be circular, whereby it is convenient for assembly. Of course, the cross-section of the limit post 111 can also be oval or polygonal, etc.

[0059] In an embodiment of the present utility model, with reference to Figure 3 as shown, the second limiting portion 21 is a lug 21a formed on the peripheral edge of the display box 20, and the limiting hole 211 penetrates through the lug 21a in the front-rear direction. For example, a downwardly protruding lug 21a is formed on the lower surface of the display box 20, and the limiting hole 211 is formed on the lug 21a and penetrates through the lug 21a. In this embodiment, by forming the limiting hole 211 on the lug 21a, the box body structure of the display box 20 does not need to be damaged, and the structure is simple.

[0060] In an embodiment of the present utility model, as Figure 7 shown, the first limiting portion 11 is formed with a first through hole, the second limiting portion 21 is provided on the outer peripheral surface of the display box 20 and is formed with a second through hole, and the first limiting portion 11 and the second limiting portion 21 are fixedly connected by a fastener 30 passing through the first through hole and the second through hole. By connecting the display box 20 and the panel 10 with the fastener 30, not only can the limiting function of the display box 20 in the left-right direction be realized, but also the fixed connection between the display box 20 and the panel 10 can be realized, further improving the limiting effect on the display box 20 and the reliability of the fixation.

[0061] In an embodiment of the present utility model, as Figure 2 and Figure 4 shown, the display box 20 may be provided with a first fixing hole 23, the panel 10 may be provided with a second fixing hole 13, and the display box 20 is fixed to the panel 10 by a fastening screw 40 passing through the first fixing hole 23 and the second fixing hole 13. Among them, the first fixing hole 23 may be formed in the upper part of the display box 20 and is located between the upper end surface and the lower end surface of the display box 20.

[0062] In an embodiment of the present utility model, the panel assembly 100 may further include: a microphone (not shown in the figure), the microphone is provided on the panel 10, the display box 20 has a connecting wire, the display box 20 is provided with a wire passing hole 24, and the connecting wire extends out of the wire passing hole 24 and is connected to the microphone.

[0063] For example, both the microphone and the display box 20 are provided on the panel 10, and the microphone is located at the lower left of the display box 20. A wire passing hole 24 is formed on the lower surface of the display box 20. One end of the connecting wire is located inside the display box 20 and is connected to the electrical components inside the display box 20. The other end of the connecting wire first passes downward through the wire passing hole 24, and then extends leftward to be connected to the microphone. Thus, the electrical connection between the microphone and the display box 20 can be realized.
