Thus, both front and rear maintenance of the power pack 200 can be achieved.
As shown in fig. 6, in some embodiments, the axes of the first and second mounting holes 221 and 222 are parallel to each other, and the axis of the first mounting hole 221 is perpendicular to the case 210. Thus, when the first connector 230 in the first mounting hole 221 is removed or when the first connector 230 in the second mounting hole 222 is removed, a force is applied in a direction perpendicular to the case 210, and the operation of applying the force is convenient.
As shown in fig. 6, in one possible implementation, the first mounting hole 221 is a blind hole, and the aperture of the first mounting hole 221 is located at the first side 223. That is, when the first connecting member 230 is inserted into the first mounting hole 221, the first connecting member 230 contacts with the bottom of the first mounting hole 221 or has a gap therebetween, and the bottom of the first mounting hole 221 provides a limit for the installation of the first connecting member 230, so that the first connecting member 230 is prevented from contacting the middle frame 110 when being installed.
In another possible implementation, as shown in fig. 6, the second mounting hole 222 is a blind hole, and the aperture of the second mounting hole 222 is located on the second side 224. That is, when the second connector 240 is inserted into the second mounting hole 222, the second connector 240 contacts with the bottom of the second mounting hole 222 or has a gap therebetween, and the bottom of the second mounting hole 222 provides a limit for the mounting of the second connector 240, so that the second connector 240 is prevented from contacting the cartridge 210 during the mounting.
As shown in fig. 4, the box body 210 includes a box body 211 and a flange 212 provided around the box body 211, and the first connecting member 230 is inserted on the flange 212.
As shown in fig. 5 and 6, the middle frame 110 includes a middle frame body 111 and a side edge 112 connected to one side of the middle frame body 111, and the second connecting member 240 is inserted into the middle frame body 111.
The end of the side 112 is abutted to the flange 212 of the power box 200 or a distance is formed between the end and the flange 212, the middle frame body 111 and the box body 211 of the power box 200 jointly enclose a mounting cavity, and the mounting piece 220 is located in the mounting cavity and abutted to the flange 212 and the middle frame body 111. Thus, the mounting member 220 is inserted between the flange 212 and the middle frame body 111, and the mounting position of the mounting member 220 is defined by the flange 212 and the middle frame body 111.
As shown in fig. 3, 4 and 5, in the present application, the power supply box 200 further includes a power supply and a control board, and the box body 211 has an accommodating cavity in which the power supply and the control board are disposed.

As shown in fig. 5, in order to stably fix the power supply box 200, in some embodiments, the number of the mounting members 220 is even, and the mounting members 220 are symmetrically disposed with respect to the symmetry axis S of the middle frame 110.
As shown in fig. 6, the mounting members 220, the first connecting members 230 and the second connecting members 240 are correspondingly arranged, that is, one mounting member 220 is connected with one first connecting member 230 and one second connecting member 240.
In a particular implementation, at least one of the first connector 230 and the second connector 240 is a screw. Accordingly, the first mounting hole 221 has internal threads therein that mate with the first connector 230, and the second mounting hole 222 has internal threads therein that mate with the second connector 240. Through threaded connection to can dismantle connection mounting part 220 and box body 210, perhaps, can dismantle connection box body 210 and display device's center 110, simple structure is stable, convenient operation, and save the cost.
Specifically, the first connecting member 230 and the second connecting member 240 may be loose screws, that is, the first connecting member 230 is separated from the first mounting hole 221 and then connected to the box 210. The second connecting member 240 is also connected to the middle frame 110 after being separated from the second mounting hole 222, thereby preventing the first connecting member 230 and the second connecting member 240 from being lost during the front maintenance or the rear maintenance.
As shown in fig. 5, 12 and 13, in some embodiments, the middle frame 110 has at least one mounting groove 113, the mounting member 220 is embedded in the mounting groove 113, and the mounting members 220 are disposed in one-to-one correspondence with the mounting grooves 113. By embedding the installation member 220 in the installation groove 113, the installation groove 113 limits the installation member 220, and the installation member 220 is prevented from rotating when the first connection member 230 and the second connection member 240 are screwed. In particular implementations, the shape of the mounting slot 113 may match the shape of the mounting member 220. Wherein, the mounting groove 113 can also be formed by two side edges 112, thus, the mounting groove 113 is convenient to form.
In an alternative embodiment, the power supply box comprises a box body and at least one mounting piece, wherein the mounting piece is provided with a first mounting hole and a second mounting hole which are arranged in a staggered mode, and the mounting piece is provided with a first side and a second side which are opposite; the first connecting piece is inserted into the first mounting hole through the first side to detachably connect the mounting piece and the box body, and the second connecting piece is inserted into the second mounting hole through the second side to detachably connect the box body and the middle frame of the display device.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the invention in its corresponding aspects.
