[0052] In some embodiments, referring to Figure 3 , Figure 4 and Figure 6 , the power component 31 is mounted on the side of the power support 32 away from the board card 33. The power support 32 is provided with a plurality of first connecting columns 321 on the side facing the power component 31. The power support 32 is connected with the power component 31 through the plurality of first connecting columns 321, so that the power component 31 is mounted on the power support 32. In this way, the power component 31 is more stable in the power assembly 100 and is not easy to deviate and damage the electrical contact with the board card 33 in the power assembly 100. The power component 31 is provided with a conductive column 311 on the side facing the power support 32. The power support 32 is provided with a via hole 323 corresponding to the conductive column 311. The conductive column 311 is electrically connected with the board card 33 through the via hole 323.

[0053] In some embodiments, the first connecting column 321 is configured as a columnar structure provided with a threaded hole on one end facing the power component 31. A plurality of screws or screws are arranged on the side of the power component 31 facing the power support 32. One screw or screw is arranged in the threaded hole of one first connecting column 321 to realize the mounting of the power component 31 on the power support 32.

[0054] In the embodiment, the conductive column 311 is configured as a copper column to realize direct electrical connection between the power supply component 31 and the board card 33. In this way, the copper column is used instead of the cable to reduce the number of cables arranged inside the power supply assembly 100, to simplify the wiring arrangement inside the power supply assembly 100, and the copper column has smaller resistance than the cable to reduce energy loss in power transmission.

[0055] In another embodiment, the conductive column 311 can also be configured as a connecting structure made of other materials, for example, made of aluminum, nickel, etc., as long as good electrical contact between the power supply component 31 and the board card 33 can be achieved.

[0056] In some embodiments, referring to Figure 3 , Figure 4 and Figure 6 , the front cover 15 is provided with a plurality of second connecting columns 322 on the side facing the board card 33, and a second connecting column 322 is fixedly connected to the power supply support 32 through a screw passing through a reserved position 332 on the board card 33, so that the power supply support 32 is installed on the front cover 15. Since the second connecting column 322 has a certain length, and the board card 33 is installed in close contact with the front cover 15, the power supply support 32 and the board card 33 have a certain spacing. In this way, the power supply support 32 separates the power supply component 31 and the board card 33, so that the heat generated by the board card 33 will not be directly conducted to the power supply component 31, causing the temperature of the power supply component 31 to be too high, and the heat generated by the power supply component 31 will not be transmitted to the board card 33, causing the temperature of the board card 33 to be too high, ensuring that the electrical components in the power supply assembly 100 can operate stably.

[0057] In some embodiments, the second connecting column 322 is provided as a columnar structure with a threaded hole at one end facing the board card 33, and a plurality of screws or bolts are provided on the side of the power supply support 32 facing the front cover 15, and a screw or a bolt is arranged in the threaded hole of a second connecting column 322 to realize the installation of the power supply support 32 on the front cover 15.

[0058] In some embodiments, referring to Figure 5 and Figure 6 , the signal controller 34 includes a signal receiver 341 and a signal socket 342 arranged on the board card 33, and the signal socket 342 is electrically connected to the signal receiver 341. The signal socket 342 is used to interface with an external signal source, so that the board card 33 can receive and decode signals, and can perform image processing on the signals to ensure that the display module 300 has better display effect.

[0059] In some embodiments, referring to Figure 7The power supply assembly 100 further comprises a terminal 50 detachably mounted in the power supply assembly 100 for connecting the cable extending into the accommodating cavity 11 through the wire conduit 13 to manage and organize the cable and prevent the cable from being entangled. The front cover 15 is further provided with a sliding groove 60 in which the terminal 50 is slidably arranged, and the length direction of the sliding groove 60 is consistent with the length direction of the front cover 15. The first limiting member 71 and the second limiting member 72 are respectively arranged on opposite sides of the length direction of the sliding groove 60. When the terminal 50 is slidably arranged in the sliding groove 60 in the length direction of the sliding groove 60, one end of the terminal 50 abuts against the first limiting member 71, and then the second limiting member 72 is detachably mounted on the side away from the first limiting member 71 to abut against the other end of the terminal 50, so that the terminal 50 is fixed in the sliding groove 60. In this way, the maintenance personnel can detach the terminal 50 and the sliding groove 60 together with the front cover 15 during the front maintenance, and the maintenance personnel can conveniently detach and repair the internal circuit of the power supply assembly 100.

[0060] Of course, the sliding groove 60 can be arranged on the front cover 15 or the power supply support 32, as long as the terminal 50 mounted in the sliding groove 60 can be detached together with the front cover 15.

[0061] In the embodiment, the first limiting member 71 is a baffle arranged on one side of the sliding groove 60, and the second limiting member 72 is a bolt or a screw, and a screw hole is arranged on the side of the sliding groove 60 away from the first limiting member 71, so that the second limiting member 72 can be arranged in the screw hole to limit the terminal 50.
