The terminal device 000 can include a display screen 100, a rear shell 200, a functional component 400, and a cover plate 300.

[0050] The display screen 100 in the terminal device 000 can be used to display a picture, wherein the display surface of the display screen 100 is a side of the display screen 100 used to display the picture.

[0051] The rear shell 200 in the terminal device 000 has a first accommodating cavity A1 between the rear surface of the display screen 100. Here, the rear surface of the display screen 100 refers to a surface opposite to the display surface of the display screen 100. The rear shell 200 can have a second accommodating cavity A2, a first opening K1, and a second opening K2. The first opening K1 in the rear shell 200 can be used to communicate the first accommodating cavity A1 and the second accommodating cavity A2. The second opening K2 in the rear shell 200 can be located on a side of the rear shell 200 away from the display screen 100, and the second opening K2 can communicate with the second accommodating cavity A2.

[0052] The functional component 400 in the terminal device 000 can be located in the first accommodating cavity A1, and the functional component 400 has a connection port P capable of being exposed from the first opening K1 in the rear shell 200. For example, the functional component 400 can include a pluggable microcomputer. Here, the functional component 400 can be externally connected to other functional devices through the connection port P to realize corresponding functions. For example, the functional component 400 can be externally connected to a sound device, a camera, or a wired mouse through the connection port P.

[0053] The cover plate 300 in the terminal device 000 can be detachably connected to the rear shell 200 at the position of the second opening K2 in the rear shell 200.

[0054] In the present application, the first opening K1 provided in the rear shell 200 can be used to communicate the first accommodating cavity A1 and the second accommodating cavity A2 in the rear shell 200, and the functional component 400 in the terminal device 000 can be located in the first accommodating cavity A1, and the connection port P in the functional component 400 can be exposed from the first opening K1. Therefore, after the cover plate 300 is detachably connected to the rear shell 200 at the position of the second opening K2, the functional component 400 can be hidden in the rear shell 200, and the part of the external connection line connected to the connection port P in the functional component 400 can be located in the second accommodating cavity A2 in the rear shell 200. In this way, the functional component 400 and the connection port P of the functional component can not be exposed, so that the appearance of the terminal device 000 can be better, and the reliability of the terminal device 000 can be improved.

[0055] In conclusion, the terminal device provided by the embodiment of the present application comprises a display screen, a back shell, functional components and a cover plate. The first opening arranged in the back shell can be used to communicate the first accommodating cavity and the second accommodating cavity in the back shell, and the functional components in the terminal device can be located in the first accommodating cavity, and the wiring port in the functional components can be exposed from the first opening. Therefore, after the cover plate is detachably connected with the back shell at the position of the second opening, the functional components can be hidden in the back shell, and the part of the external wiring connected with the wiring port in the functional components can be located in the second accommodating cavity in the back shell. In this way, it can be ensured that the functional components and the wiring port of the functional components are not exposed, so that the appearance of the terminal device is better, and the reliability of the terminal device is improved.

[0056] In the embodiment of the present application, please refer to Figure 4 , Figure 4 is a structural schematic diagram of a back shell provided by the embodiment of the present application. The inside of the second accommodating cavity A2 in the back shell 200 can have a support table 201. Wherein, the side of the support table 201 facing the second opening K2 can be adsorbed and connected with the cover plate 300. For example, the side of the support table 201 facing the second opening K2 can be magnetically adsorbed and connected with the cover plate 300. In this way, through the cooperation of the support table 201 in the back shell 200 and the cover plate 300, the back shell 200 and the cover plate 300 can be stably connected together. Therefore, after the back shell 200 and the cover plate 300 are connected together, it can be ensured that the functional components 400 and the wiring port P of the functional components can be hidden in the back shell 200, so that the functional components 400 and the wiring port P of the functional components are not exposed.

[0057] In the present application, please refer to Figure 5 and Figure 6 , Figure 5 is a cooperation schematic diagram of a back shell and a first magnet provided by the embodiment of the present application, Figure 6 is a structural schematic diagram of a cover plate provided by the embodiment of the present application. The side of the support table 201 facing the display screen 100 can have a bearing groove U. The terminal device 000 can further comprise a first magnet 500 fixed in the bearing groove U. For example, the first magnet 500 can be a permanent magnet.

[0058] The cover plate 300 in the terminal device 000 can comprise a cover plate body 301 and a second magnet 302 fixedly connected with one side of the cover plate body 301. For example, the second magnet 302 can be a magnetic suction sheet. It should be noted that the second magnet 302 can have a screw hole, and the second magnet 302 can be fixedly connected with the cover plate 300 through a screw.

[0059] The side of the cover plate body 301 where the second magnet 302 is distributed is located on the support table 201, and the first magnet 500 can be magnetically connected with the second magnet 302. In this way, through the magnetic attraction between the first magnet 500 and the second magnet 302, the cover plate 300 and the rear shell 200 can be firmly connected together.

[0060] In the present application, as shown in Figure 6 The cover plate body 301 in the cover plate 300 can have two first side edges A1 arranged opposite to each other and two second side edges A2 arranged opposite to each other. The second magnet 302 in the cover plate 300 can include a first magnetic strip 302a distributed at the position of one first side edge A1 and a second magnetic strip 302b distributed at the position of one second side edge A2. The extension direction of the first magnetic strip 302a in the second magnet 302 intersects the extension direction of the second magnetic strip 302b. For example, the extension direction of the first magnetic strip 302a in the second magnet 302 is perpendicular to the extension direction of the second magnetic strip 302b.

[0061] In the embodiments of the present application, please refer to Figure 6 The end of the first magnetic strip 302a in the second magnet 302 can be connected with the end of the second magnetic strip 302b. That is, the first magnetic strip 302a in the second magnet 302 can be connected with the second magnetic strip 302b as an integral structure.

[0062] In the present application, as shown in Figure 6 The length of the first side edge A1 in the cover plate 300 can be greater than the length of the second side edge A2, and the length of the first magnetic strip 302a in the second magnet 302 can be greater than the length of the second magnetic strip 302b. For example, the shape of the second magnet 302 can be L-shaped.

[0063] Here, the number of support tables 201 in the rear shell 200 can be multiple, and the number of support tables 201 for magnetically connecting with the first magnetic strip 302a can be more than the number of support tables 201 for magnetically connecting with the second magnetic strip 302b. For example, the number of support tables 201 for magnetically connecting with the first magnetic strip 302a can be 3, and the number of support tables 201 for magnetically connecting with the second magnetic strip 302b can be 1. That is, the number of first magnets 500 for magnetically connecting with the first magnetic strip 302a can also be 3, and the number of first magnets 500 for magnetically connecting with the second magnetic strip 302b can also be 1. In this way, through the magnetic attraction between the first magnetic strip 302a and the multiple first magnets 500 and the magnetic attraction between the second magnetic strip 302b and the first magnet 500, the cover plate 300 and the rear shell 200 can be more firmly connected together.

[0064] In the embodiment of the present application, the two first side edges A1 in the cover plate body 301 in the cover plate 300 for distributing the first side edges A1 of the first magnetic strips 302a in the second magnet 302 can be more away from the first opening K1 in the back shell 200 than the other first side edge A1.

[0065] In the present application, please refer to Figure 4 , Figure 6 and Figure 7 , Figure 7 is another structural schematic diagram of a cover plate provided by the embodiment of the present application. The cover plate 300 can further include a first clamping member 303, which can be fixedly connected with the first side edge A1 in the cover plate body 301 away from the side of the first magnetic strips 302a in the second magnet 300. The back shell 200 in the terminal device 000 can further have a second clamping member 202 cooperating with the first clamping member 303. Here, the second clamping member 202 can be distributed at a position close to the second opening K2.

[0066] In the present application, please refer to Figure 8 , Figure 8 is a cooperation schematic diagram of a first clamping member and a second clamping member provided by the embodiment of the present application. After the side of the cover plate body 301 in the cover plate 300 distributing the second magnet 302 is located on the support table 201 in the back shell 200, the first clamping member 303 in the cover plate 300 can be clamped with the second clamping member 202 in the back shell 200. Here, in the process of connecting the cover plate 300 with the back shell 200, through the cooperation of the first clamping member 303 in the cover plate 300 and the second clamping member 202 in the back shell 200, the cover plate 300 and the back shell 200 can be more accurately connected together. In addition, after the side of the cover plate body 301 in the cover plate 300 distributing the second magnet 302 is located on the support table 201 in the back shell 200, through the clamping of the first clamping member 303 in the cover plate 300 and the second clamping member 202 in the back shell 200, the stability of the connection between the cover plate 300 and the back shell 200 can be further improved.

[0067] It should be noted that the clamping amount between the first clamping member 303 in the cover plate 300 and the second clamping member 202 in the back shell 200 can be small. In this way, it can be ensured that the first clamping member 303 and the second clamping member will not be affected by the relatively tight clamping, thereby affecting the subsequent disassembly between the cover plate 300 and the back shell 200.

[0068] In the embodiment of the present application, as Figure 6 and Figure 7As shown, the cover plate body 301 in the cover plate 300 can also have a notch 300a, which can be located at the position of the second side edge A2 on the side of the cover plate body 301 away from the second magnetic strip 302b in the second magnet 200. Wherein, after the side of the cover plate body 301 where the second magnet 302 is distributed is located on the support table 201, the notch 300a in the cover plate body 301 can be in communication with the second accommodating cavity A2 in the rear shell 200. Here, the notch 300a in the cover plate body 301 can facilitate the user to take the cover plate 300. For example, the user can take the cover plate 300 from the rear shell 200 by taking the position of the notch 300a with his hand, and similarly, the user can connect the cover plate 300 to the rear shell 200 at the position of the second opening K2 by taking the position of the notch 300a with his hand.

[0069] In the embodiments of the present application, please refer to Figure 9 , Figure 9 is another schematic diagram of the back of a terminal device provided by the embodiments of the present application. The terminal device 000 can also include a cable 600 connected to the wiring port P of the functional component 400. A part of the cable 600 in the terminal device 000 can be distributed in the second accommodating cavity A2, and another part of the cable 600 can extend out of the second accommodating cavity A2 through the notch 300a in the cover plate 300. Here, one end of the cable 600 can be connected to the wiring port P of the functional component 400, and the other end of the cable 600 can be connected to the wiring port of another functional device, that is, the end of the cable 600 extending out of the second accommodating cavity A2 can be connected to the wiring port of another functional device, for example, the end of the cable 600 extending out of the second accommodating cavity A2 can be connected to the wiring port of a sound device, a camera or a wired mouse.

[0070] In the present application, as Figure 9 shown, the terminal device 000 can also include a plurality of cable clamping structures 700 fixed in the second accommodating cavity A2. Wherein, the cable clamping structure 700 can be used to clamp the part of the cable 600 distributed in the second accommodating cavity A2. In this way, the cable clamping structure 700 can limit the part of the cable 600 distributed in the second accommodating cavity A2, so as to ensure that the part of the cable 600 distributed in the second accommodating cavity A2 is relatively neat and orderly. In addition, when the user pulls the cable 600, the cable clamping structure 700 can buffer the pulling force, so as to ensure that the wiring port P connected to the cable 600 will not be damaged due to the excessive pulling force.

[0071] In the embodiments of the present application, please refer to Figure 9The side of the back shell 200 in the terminal device 000, which is away from the display screen 100, has a plurality of hooking holes 200a. The hooking holes 200a in the back shell 200 can be clamped with hooks arranged on the support frame, so that the terminal device 000 can be stably connected with the support frame.

[0072] In the present application, first, the user can take the gap 300a in the cover plate 300 with his hand to take the cover plate 300 from the back shell 200, then the user can insert the cable 600 into the wiring port P in the functional component 400, after the cable 600 is inserted into the wiring port P in the functional component 400, the user can clamp the part of the cable 600 distributed in the second accommodating cavity A2 with the cable clamping structure 700, finally, the user can take the gap 300a in the cover plate 300 with his hand, align the cover plate 300 with the second opening K2 in the back shell 200, and connect the cover plate 300 with the back shell 200.

[0073] In summary, the terminal device provided by the present application comprises a display screen, a back shell, a functional component, and a cover plate. The first opening arranged in the back shell can be used to communicate the first accommodating cavity and the second accommodating cavity in the back shell, and the functional component in the terminal device can be located in the first accommodating cavity, and the wiring port in the functional component can be exposed from the first opening. Therefore, after the cover plate is detachably connected with the back shell at the position of the second opening, the functional component can be hidden in the back shell, and the part of the external cable connected with the wiring port in the functional component can be located in the second accommodating cavity in the back shell. In this way, the functional component and the wiring port in the functional component can not be exposed, so that the appearance of the terminal device is better, and the reliability of the terminal device is improved.

[0074] The present application also provides another terminal device, which can hide the back screws.
