[0035] In the present embodiment, the base 100 is in a circular shape as a whole. The circular base 100 can reduce the area occupied by the base 100, thereby facilitating fixing the base 100 in the car. The connector 500 can detachably connect the base 100 to the center console of the car. The display screen body 200 includes a frame 210 and a screen 220 embedded in the frame 210.

[0036] By adopting the above technical solution, the angle of the display screen body 200 can be indirectly adjusted by the first adjustment mechanism 310 and the second adjustment mechanism 320. The first adjustment mechanism 310 and the second adjustment mechanism 320 can indirectly adjust the angle of the display screen body 200 along two different directions, so that users of different heights can more clearly and conveniently observe the content displayed on the display screen body 200 by adjusting the angle of the display screen body 200, so that the vehicle-mounted display screen can be suitable for users of different heights; the height of the first adjustment mechanism 310 can be adjusted by the height adjustment device 400, so that the first adjustment mechanism 310 adjusts the height of the display screen body 200, so that users of different heights can further more clearly and conveniently observe the content displayed on the display screen body 200 by adjusting the height of the display screen body 200, so that the vehicle-mounted display screen can be further suitable for users of different heights; by adopting the setting of the connecting member 500, the base 100 can be detachably connected in the car, so as to facilitate the installation and disassembly of the vehicle-mounted display screen, so that the vehicle-mounted display screen is suitable for different cars or different positions in the car, and the applicability of the vehicle-mounted display screen is further improved.

[0037] Combination Figures 1 to 4 The height adjustment device 400 includes a support frame 410 and a height adjustment component 420. The display screen body 200 is slidably connected in the support frame 410. The height adjustment component 420 is arranged on the support frame 410, and the height adjustment component 420 is used to drive the display screen body 200 to move in the support frame 410.

[0038] In this embodiment, the support frame 410 is arranged in a long direction as a whole, and the rectangular support frame 410 is arranged in a vertical direction. The display screen body 200 is slidably connected in the support frame 410 along the length direction of the rectangular support frame 410; in other embodiments, the support frame 410 can also be replaced with a separate support rod, and the height of the display screen body 200 can also be adjusted by sliding the display screen body 200 along the length direction of the support rod to connect it to the support rod.

[0039] By adopting the above technical solution, the display screen body 200 is slidably connected in the support frame 410, and the display screen body 200 is driven to move in the support frame 410 by the height adjustment component 420, so as to adjust the height of the display screen body 200. The support frame 410 is simple in structure, and the height adjustment effect of the display screen body 200 is improved. In addition, the support frame 410 can protect the display screen body 200 and prevent the display screen body 200 from being damaged.

[0040] Combination Figures 1 to 4The supporting frame 410 has two opposite sides with slide grooves 411 , and the display screen body 200 has two sliders 230 on both sides, and the sliders 230 on both sides are slidably connected in the slide grooves 411 on both sides.

[0041] In this embodiment, the slider 230 is fixedly connected to the frame 210 of the display screen body 200, the cross-section of the slide groove 411 is set to a "U" shape, and the slider 230 is matched with the "U"-shaped slide groove 411; in other embodiments, the cross-section of the slide groove 411 can be set to a "T" shape or a dovetail shape, and the slider 230 is matched with the "T"-shaped or dovetail-shaped slide groove 411, which can prevent the slider 230 from detaching from the slide groove 411.

[0042] By adopting the above technical solution, the setting of the slide groove 411 and the slider 230 can guide the movement of the display screen body 200, improve the sliding effect of the display screen body 200 slidingly connected in the support frame 410, thereby indirectly improving the adjustment effect of the height of the display screen body 200.

[0043] Combination Figures 1 to 4 The height adjustment assembly 420 includes a lead screw 421 and a height adjustment motor 422. The lead screw 421 is rotatably connected in the slide groove 411. The slider 230 is sleeved and threadedly connected to the lead screw 421. The height adjustment motor 422 is arranged on the support frame 410, and the height adjustment motor 422 is used to drive the lead screw 421 to rotate.

[0044] In this embodiment, the height adjustment motor 422 is configured as a brake stepper motor, and the height adjustment motor 422 is located in the support frame 210; a stepper motor is a motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. For each input pulse signal, the rotor rotates an angle or moves forward one step. The output angular displacement or linear displacement is proportional to the input number of pulses, and the rotation speed is proportional to the pulse frequency; the use of a stepper motor improves the accuracy of the height adjustment of the display screen body 200.

[0045] By adopting the above technical solution, the height adjustment motor 422 drives the lead screw 421 to rotate. Since the slider 230 is slidably connected in the slide groove 411, the slider 230 will not rotate along with the rotation of the lead screw 421, so that the slider 230 moves on the lead screw 421. The height adjustment motor 422 drives the lead screw 421 to rotate forward and reverse, so that the slider 230 drives the display screen body 200 to rise and fall. The arrangement of the lead screw 421 and the height adjustment motor 422 can fix the display screen body 200 to any adjusted position, thereby further improving the height adjustment effect of the display screen body 200.

[0046] Combination Figures 1 to 4The height adjustment device 400 also includes a synchronous member 600. Two lead screws 421 are provided. The two lead screws 421 are rotatably connected in the slide grooves 411 on both sides. The synchronous member 600 is configured to synchronously drive the other lead screw 421 to rotate when the height adjustment motor 422 drives one of the lead screws 421 to rotate.

[0047] By adopting the above-mentioned technical solution, by setting two lead screws 421, the two lead screws 421 can simultaneously drive the sliders 230 on both sides to drive the display screen body 200 to move, thereby improving the driving effect of the height adjustment of the display screen body 200; the setting of the synchronization member 600 can enable the same height adjustment motor 422 to simultaneously drive the two lead screws 421 to rotate, preventing the different moving speeds of the slider 230 due to the asynchronous rotation of the two lead screws 421, and further improving the driving effect when the height of the display screen body 200 is adjusted.

[0048] Combination Figures 1 to 4 The synchronous component 600 includes a synchronous wheel 610 and a synchronous belt 620. The synchronous wheels 610 are sleeved on and fixedly connected to the two lead screws 421, and the synchronous belt 620 is wound around the synchronous wheels 610 on both sides at the same time.

[0049] In this embodiment, the synchronous wheel 610 is configured as a pulley, and the synchronous belt 620 is configured as a belt; in other embodiments, the synchronous component 600 may include a chain and a sprocket, and the sprocket is sleeved and fixedly connected to the two lead screws 421, and the chain is simultaneously wound around the two sprockets, so that the chain and the sprocket can also achieve synchronous driving of the two lead screws 421.

[0050] By adopting the above technical solution, when the high-speed adjustment motor drives one of the lead screws 421 to rotate, the lead screw 421 can drive one of the synchronous wheels 610 to rotate, so that the synchronous wheel 610 drives the synchronous belt 620 to transmit, so that the synchronous belt 620 drives the other synchronous wheel 610 to rotate, so that the other synchronous wheel 610 drives the other lead screw 421 to rotate, so that the two lead screws 421 can rotate synchronously. The arrangement of the synchronous wheel 610 and the synchronous belt 620 has a simple structure, which improves the driving effect of the synchronous drive of the two lead screws 421.

[0052] In this embodiment, the rotation axis of the tray 312 is arranged in the vertical direction, and the width of the tray 312 is the same as the width of the bottom of the support frame 410. The tray 312 can be set as a separate rod body or as a circular or rectangular disk; the first motor 311 is set as a brake stepper motor. The stepper motor is a motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. For each input pulse signal, the rotor rotates an angle or moves forward one step. The output angular displacement or linear displacement is proportional to the input number of pulses, and the rotation speed is proportional to the pulse frequency; the use of a stepper motor setting improves the accuracy of the angle adjustment of the display screen body 200.

[0053] By adopting the above technical solution, the tray 312 is driven to rotate by the first motor 311, so that the tray 312 drives the support frame 410 to rotate, thereby facilitating the adjustment of the angle of the display screen body 200 in the support frame 410, so that users of different heights can conveniently view the content displayed on the display screen body 200; the setting of the first motor 311 and the tray 312 has a simple structure, improves the driving effect of the tray 312, and thus improves the adjustment effect of the angle of the display screen body 200.

[0054] Combination Figures 1 to 4 The second adjustment mechanism 320 includes a connecting block 321 and a second motor 322. The connecting blocks 321 are set between the display screen body 200 and the sliders 230 on both sides. The second motor 322 is set in the connecting block 321, and the second motor 322 is used to drive the support frame 410 to rotate. The rotation axis of the support frame 410 is perpendicular to the rotation axis of the tray 312.

[0055] In this embodiment, the rotation axis of the support frame 410 is arranged in the horizontal direction, one side of the connecting block 321 is fixedly connected to the frame 210 of the display screen body 200, and the other side is fixedly connected to the slider 230; the second motor 322 is located in the connecting block 321, and the second motor 322 is arranged as a brake stepper motor.

The output angular displacement or linear displacement is proportional to the input pulse number, and the rotation speed is proportional to the pulse frequency. The stepper motor is used to improve the angle adjustment accuracy of the display screen body 200.

[0056] By adopting the above technical solution, the support frame 410 is driven to rotate by the second motor 322, so as to further adjust the angle of the display screen body 200, so that users of different heights can further conveniently view the content displayed on the display screen body 200; the setting of the second motor 322 has a simple structure, and improves the adjustment effect of the angle adjustment of the display screen body 200; by making the rotation axis of the support frame 410 perpendicular to the rotation axis of the tray 312, the angle of the display screen body 200 is adjusted along two mutually perpendicular directions, thereby increasing the adjustment range of the angle adjustment of the display screen body 200, and further facilitating users to view the content displayed on the display screen body 200.

[0057] Combination Figures 1 to 4 The connecting member 500 includes a double-sided tape 510, which is disposed on the base 100.
