[0051] For specific technical solutions, please refer to Figure 5 and Figure 6As shown, the auxiliary reinforcement unit 3 includes a reinforcement bar 301, a movable slider 302, a bracket 303 and an L-shaped fixing bracket 304. Two reinforcement bars 301 are provided. The two reinforcement bars 301 are fixedly arranged at the back position of the display screen assembly 103. A sliding groove is provided on the two reinforcement bars 301. The reinforcement bar 301 is slidably connected to the movable slider 302. One end of the movable slider 302 is rotatably connected to one end of the bracket 303. The other end of the bracket 303 is rotatably connected to one end of the L-shaped fixing bracket 304. The other end of the shaped fixing frame 304 is fixedly connected to the side wall of the portable computer body 1.

At the same time, the auxiliary reinforcement unit 3 of the present application can automatically deform and adapt when the display screen assembly 103 is flipped open or covered, which is convenient and flexible to use.

[0052] As a preferred technical solution, please refer to Figure 7 Figure 8 and Figure 9 As shown, the auxiliary cleaning unit 4 includes a half gear 401, a rotating rod 402, a gear A403, a rotating disk 404, a rocker 405, a guide movable plate 406, a tooth plate 407, a rotating shaft 408, a gear portion 409, a disc 410, a contact plate 411, a fixed cylinder 412, a movable piston 413, a movable rod 414, a contact frame 415, a pressure-increasing spring 416, and an output hose 418. The half gear 401 is fixedly arranged at the side position of the display screen assembly 103, and the rotating rod 402 is arranged on the portable computer body 1 The rotating rod 402 is fixedly connected to the bottom inner cavity of the portable computer body 1 and is rotatably connected to the portable computer body 1. A gear A403 is fixedly connected to one end of the rotating rod 402. The gear A403 and the half gear 401 are meshed with each other. According to the technical solution, when the display screen assembly 103 is flipped and closed, the flipping of the display screen assembly 103 can drive the half gear 401 to rotate, thereby driving the gear A403 to rotate. The rotation of the gear A403 can drive the rotating rod 402 to rotate, thereby realizing the automatic rotation function of the rotating rod 402.

[0053] The rotating rod 402 is fixedly connected to a rotating disk 404, and one end of a rocker 405 is rotatably connected to the rotating disk 404. The guide movable plate 406 is arranged in the inner cavity of the portable computer body 1 and slides with the portable computer body 1. One end of the guide movable plate 406 is rotatably connected to one end of the rocker 405. A toothed plate 407 is fixedly connected to the side wall of the guide movable plate 406. The rotating shaft 408 is arranged in the inner cavity of the portable computer body 1 and rotatably connected to the portable computer body 1. The arc-shaped wall of the rotating shaft 408 is fixedly connected to the side wall of the guide movable plate 406. A gear portion 409 is fixedly connected, and the gear portion 409 and the tooth plate 407 are meshed with each other. A disc 410 is fixedly connected to the arc-shaped wall of the rotating shaft 408. Through this technical solution, when the rotating rod 402 rotates, the rotation of the rotating rod 402 can drive the rotating disk 404 to rotate, thereby driving one end of the rocker 405 to be pulled and moved, thereby driving the guide movable plate 406 to move, and the movement of the guide movable plate 406 can drive the tooth plate 407 to rotate, and the movement of the tooth plate 407 can drive the gear portion 409 to rotate.

[0054] For further technical solutions, see Figure 10 As shown, the gear portion 409 includes a ratchet 4091, an outer wheel 4092, a pawl 4093, a limit spring 4094 and an outer gear 4095. The ratchet 4091 is fixedly arranged on the arc-shaped wall of the rotating shaft 408. The outer wheel 4092 is sleeved on the ratchet 4091 and is rotatably connected to the ratchet 4091. The pawl 4093 is rotatably connected to the arc-shaped inner wall of the outer wheel 4092. One end of the pawl 4093 extends to the ratchet 4091. The side wall of the pawl 4093 is fixedly connected to one end of the limit spring 4094. The other end of the limit spring 4094 is fixed to the outer wheel 409 2, the arc wall of the outer wheel 4092 is fixedly connected with an outer gear 4095, and the outer gear 4095 and the tooth plate 407 are meshed with each other. Through the present technical solution, the reciprocating movement of the tooth plate 407 can drive the outer gear 4095 to rotate reciprocatingly. When the outer gear 4095 rotates clockwise, the torque cannot be transmitted to the rotating shaft 408, thereby causing the outer gear 4095 to idle. When the outer gear 4095 rotates counterclockwise, it can drive the ratchet 4091 to rotate, thereby driving the rotating shaft 408 to rotate counterclockwise, thereby realizing the function of unidirectional torque transmission.

[0055] For specific technical solutions, please refer to Figure 11 and Figure 12 As shown, a plurality of contact plates 411 are fixedly provided on the arc-shaped wall of the disc 410. Through this technical solution, when the rotating shaft 408 rotates counterclockwise, the disc 410 can be driven to rotate counterclockwise.

[0056] The fixed cylinder 412 is fixedly arranged in the inner cavity of the portable computer body 1, and a movable piston 413 is slidably connected to the inner cavity of the fixed cylinder 412. One end of a movable rod 414 is fixedly connected to one side of the movable piston 413. The other end of the movable rod 414 passes through the inner cavity side wall of the fixed cylinder 412 and extends to the outside of the wall. One end of the movable rod 414 is fixedly connected to a contact frame 415. One end of the contact frame 415 extends to the contact plate 411. One end of the fixed cylinder 412 is fixedly connected to the inner cavity of the portable computer body 1. There is one end of a pressure-boosting spring 416, the other end of the pressure-boosting spring 416 extends to the contact frame 415 and is fixedly connected to the contact frame 415, the bottom side of the inner cavity of the fixed cylinder 412 is fixedly connected to an air inlet nozzle 417, an input one-way valve is installed on the air inlet nozzle 417, the bottom side of the inner cavity of the fixed cylinder 412 is fixedly connected to one end of an output hose 418, the other end of the output hose 418 extends into the inner cavity of the support bar 105 and is fixedly connected to the support bar 105. Through this technical solution, as Figure 8 From the perspective shown, when the rotating shaft 408 rotates counterclockwise, the disc 410 can be driven to rotate, thereby driving the contact plate 411 to rotate counterclockwise. The rotation of the contact plate 411 can drive the contact frame 415 to move upward, thereby driving the movable piston 413 to move upward, so that the fixed cylinder 412 can inhale air through the air inlet nozzle 417. At the same time, the booster spring 416 is also continuously stretched, accumulating elastic potential energy. As the contact plate 411 continues to rotate, it will eventually separate from the contact frame 415. Since the contact frame 415 loses the limiting effect of the contact plate 411, the stretched booster spring 416 rebounds quickly, driving the contact frame 415 moves, thereby pressing down the moving piston 413, and the spring rebound effect causes the moving piston 413 to press down quickly, thereby causing the gas to be pressurized and ejected, and released through the small hole 1051 on the support bar 105, and the released airflow is used to blow and clean foreign matter on the surface of the display screen assembly 103. It can be seen from the above description that in the process of covering the display screen assembly 103, the function of automatic pressurized blowing can be realized by the auxiliary cleaning unit 4, thereby avoiding the problem of the screen being squeezed and broken during the subsequent covering process due to the attachment of hard foreign matter to the screen position when used for a long time in a complex outdoor environment.

[0057] For further technical solutions, see Figure 13As shown, the interface protection unit 5 includes a fixed shell 501, a limiting cylinder 502, a protective baffle 503, a rack 504 and a gear B505. The fixed shell 501 is fixedly arranged at the side of the portable computer body 1 and is located below the interface slot assembly 106. The limiting cylinder 502 is fixedly connected to the inner cavity of the fixed shell 501. The protective baffle 503 is provided with a guide groove. The guide groove of the protective baffle 503 is arranged at the limiting cylinder 502 and slides with the limiting cylinder 502. The side of the protective baffle 503 A rack 504 is fixedly connected to the edge, and the gear B505 is arranged in the inner cavity of the fixed shell 501 and is rotatably connected to the fixed shell 501. The gear B505 is fixedly connected to the rotating rod 402. Through the present technical solution, when the display screen assembly 103 is flipped and covered, the rotating rod 402 can be driven to rotate, so that the rotation of the rotating rod 402 can drive the rack 504 to move, thereby driving the protective baffle 503 to move, so that the protective baffle 503 moves up to cover the interface slot assembly 106, thereby playing the function of automatic protection.

[0058] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art.
