[0034] Figure 1 This is one of the disassembled schematic diagrams of the seatback display 10 in this application; Figure 2 This is the second disassembly diagram of the seatback display 10 in this application; Figure 3 One of the schematic diagrams of connecting the control module 100 with display modules 200 of different sizes; Figure 4FIG2 is a second schematic diagram of connecting the control module 100 with display modules 200 of different sizes. Figure 1-Figure 4 As shown, the seatback display 10 in the present application includes a control module 100 and a display module 200, and the control module 100 and the display module 200 are detachably connected. The control module 100 includes a first housing 110 and a control unit 120. Among them, a first mounting structure 111 is provided on the first housing 110, and the first mounting structure 111 is detachably connected to a second mounting structure 211 of the display module 200. The control unit 120 is installed on the housing, and a first interface 123 is provided on the control unit 120, and the first interface 123 is used to be electrically connected to the display module 200.

[0035] As described above, by installing the control unit 120 on the housing, the control unit 120 can be separated from the display module 200, so that the control unit 120 is located on the control module 100. Therefore, when the seat back display 10 fails, the control module 100 or the display module 200 can be easily replaced through the detachable connection between the first mounting structure 111 and the display module 200, thereby reducing the difficulty of maintenance. In addition, by installing the first circuit board 121 on the housing, the control unit 120 is located in the control module 100, so that the control module 100 can be replaced as shown in FIG. Figure 3 , Figure 4 As shown, the display modules 200 of different sizes and models are adapted and installed, so that products of different configurations can be generated.

Therefore, the control unit 120 can be easily disassembled and installed.

[0038] In some embodiments, Figure 1 , Figure 2 As shown, a controller 125 is mounted on the second circuit board 122, and the second circuit board 122 is located between the first circuit board 121 and the bottom of the groove 112. Therefore, since the temperature of the controller 125 is relatively high during operation, the second circuit board 122 is disposed between the first circuit board 121 and the bottom of the groove 112, so that the display module 200 and the second circuit board 122 can be separated on both sides of the first circuit board 121, thereby preventing the heat generated by the controller 125 from affecting the display module 200.

[0039] In some embodiments, Figure 1 As shown, the groove bottom of the groove 112 is provided with heat dissipation teeth 115. Thus, by providing the heat dissipation teeth 115 at the groove bottom of the groove 112, the heat dissipation performance of the controller 125 on the second circuit board 122 can be improved to prevent the controller 125 from being damaged due to excessive temperature.

[0040] In some embodiments, Figure 1 , Figure 2 As shown, the second circuit board 122 is fixed to the first circuit board 121 by bolts, and the first circuit board 121 and the second circuit board 122 are plug-in connected by an electrical connector. Thus, the first circuit board 121 and the second circuit board 122 can be easily connected and separated.

[0041] In some embodiments, Figure 1 , Figure 2 As shown, the display module 200 includes a second housing 210 and a display screen 220. The second mounting structure 211 is disposed on the back of the second housing 210. The display screen 220 is mounted on the second housing 210. The display screen 220 is provided with a second interface 221 which is electrically connected to the first interface 123.

[0042] In some embodiments, Figure 1 , Figure 2As shown, the first mounting structure 111 includes a mounting hole and a hand-loosen captive screw 113, and the second mounting structure 211 includes a threaded hole, and the hand-loosen captive screw 113 is passed through the mounting hole and threadedly connected with the threaded hole. Therefore, the first housing 110 and the control module 100 are mounted on the second housing 210 and the display module 200 by hand-loosening the captive screw 113, which can facilitate the installation and separation between the control module 100 and the display module 200.

[0043] like Figure 3 , Figure 4 As shown, in some embodiments, the second housing 210 and the display screen 220 are provided with a plurality of different sizes, that is, the second mounting structure 211 of the display modules 200 of different sizes is the same, the second housing 210 and the display screen 220 have different sizes, and the same control module 100 is installed on the second mounting structure 211 through the first mounting structure 111, and after the first interface 123 is electrically connected to the second interface 221, the control module 100 can control the display module 200 to work. Thus, by providing the second housing 210 and the display screen 220 with a plurality of different sizes, the control module 100 can be adapted to the display modules 200 of different sizes and models, so that when the seatback displays 10 of different models and sizes fail, the same control module 100 can be used for repair and replacement, thereby further reducing the difficulty of repair.
