DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] Embodiment 1:

[0036] Reference Figure 1-Figure 10 A vehicle-mounted LCD display screen structure comprises a mounting plate 1 and a display screen body 102 connected to the mounting plate 1, the mounting plate 1 is provided with a placement groove 101 for placing the display screen body 102, and a circular arc bottom plate 2 corresponding to the display screen body 102 is slidably connected in the placement groove 101; a first groove 103 and a second groove 105 are provided in the mounting plate 1, a first rack plate 201 is provided at the bottom of the circular arc bottom plate 2, a positioning component is connected to one end of the first rack plate 201 placed in the first groove 103, and a reset component is provided in the second groove 105; an arc groove 106 is provided on the top of the mounting plate 1, a rotating shaft 7 is rotatably connected in the circular arc groove 106, and an arc top plate 701 matching the display screen body 102 is fixedly connected to the rotating shaft 7.

[0037] In the present invention, when installation is required, first place the mounting plate 1 in the groove at the center console of the car. Of course, when it needs to be installed in other positions, the same operation can be used. Then place the display screen body 102 in the placement groove 101 on the mounting plate 1, and then press the display screen body 102 downward to push the arc bottom plate 2 to move. At this time, the arc bottom plate 2 will drive the first rack plate 201 to move downward, thereby driving the positioning component to work, so that the first rack plate 201 will not move upward again after moving downward, thereby positioning the arc bottom plate 2. At the same time, the arc top plate 701 in the arc groove 106 rotates to resist the top of the display screen body 102, thereby fixing the display screen body 102 to make it easy to use, and the display screen body 102 can be easily taken out through the reset component.

[0038] Embodiment 2:

[0039] Reference Figure 1-Figure 7 A vehicle-mounted LCD display screen structure includes a mounting plate 1 and a display screen body 102 connected to the mounting plate 1, the mounting plate 1 is provided with a placement groove 101 for placing the display screen body 102, and a circular arc bottom plate 2 corresponding to the display screen body 102 is slidably connected in the placement groove 101; a first groove 103 and a second groove 105 are provided in the mounting plate 1, and a first rack plate 201 is provided at the bottom of the circular arc bottom plate 2, and a positioning component is connected to one end of the first rack plate 201 placed in the first groove 103.

[0040] The positioning assembly includes a first driven shaft 3 rotatably connected in the first groove 103, a first gear 301 fixedly connected to the first driven shaft 3, and a second rack plate 4 slidably connected in the first groove 103. The first rack plate 201 and the second rack plate 4 are both meshed with the first gear 301. A first clamping block 402 is provided at the bottom of the second rack plate 4. A second clamping block 606 that cooperates with the first clamping block 402 is rotatably connected in the first groove 103.

[0041] The inner wall of the first groove 103 is rotatably connected with the second driven shaft 605, the second clamping block 606 is fixedly connected to the second driven shaft 605, the first clamping block 402 and the second clamping block 606 are provided with mutually matching inclined surfaces, a slide groove 104 is provided in the first groove 103, a protrusion 401 is provided on the outer wall of the second rack plate 4, the protrusion 401 is slidably connected in the slide groove 104, and a torsion spring 609 is sleeved on the outer wall of the second driven shaft 605, and the torsion spring 609 is arranged between the second clamping block 606 and the inner wall of the first groove 103.

[0042] In the present invention, the display screen body 102 is pressed downward so that it pushes the arc bottom plate 2 to move. At this time, the arc bottom plate 2 will drive the first rack plate 201 to move downward, thereby driving the positioning component to work, so that the first rack plate 201 will not move upward again after moving downward, thereby positioning the arc bottom plate 2. At the same time, the arc top plate 701 in the arc groove 106 rotates to resist the top of the display screen body 102, thereby fixing the display screen body 102 and making it easy to use. The display screen body 102 can be easily taken out through the reset component.

[0043] The specific operation process of the positioning assembly is as follows: press the display screen body 102 downward to drive the arc bottom plate 2 to move, thereby driving the first rack plate 201 at the bottom to move, and the first rack plate 201 will drive the first gear 301 meshing with it to rotate, thereby driving the second rack plate 4 to move, so that the first block 402 at the bottom of the second rack plate 4 also moves with it, and when the first block 402 squeezes the second block 606, the inclined surfaces on the two will contact each other, and at this time the first block 402 continues to move It will drive the second card block 606 that abuts against it to rotate. When the first card block 402 moves to the right side of the second card block 606, the first card block 402 and the non-inclined end of the second card block 606 will abut against each other. A limiting plate 607 that cooperates with the second card block 606 is fixedly connected in the first groove 103. Therefore, the second card block 606 will not rotate, so that the second rack plate 4 is limited by the first card block 402, so that the position of the arc bottom plate 2 is fixed, so that it will not lift up the display screen body 102.

[0044] Among them, the first rack plate 201 and the second rack plate 4 are staggered. When the first rack plate 201 moves downward, it will not touch the second rack plate 4, avoiding interference between the two when they are used. The protrusion 401 on the outer wall of the second rack plate 4 slides in the slide groove 104, so that the movement of the second rack plate 4 is more stable, and the torsion spring 609 can make the second block 606 automatically reset after rotation, which is convenient for repeated use.

When the second clamping block 606 rotates, it will no longer resist the first clamping block 402, and then under the action of the first spring 205, the arc bottom plate 2 will be reset, thereby driving the first rack plate 201, the first gear 301 and the second rack plate 4 to reset, and the display screen body 102 can be conveniently taken out.

[0051] Among them, the second spring 603 is set to make the roller 601 always against the outer wall of the cone block 5, so as to facilitate use, and the cross-sectional shape of the square rod 502 is rectangular. When the cone block 5 moves, it will move on the square rod 502, thereby limiting the cone block 5 and making it easy to move.
