[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figure 1-6This utility model provides the following technical solution: a vehicle-mounted display screen host device, including a display screen body 1, a terminal block 3 fixedly connected to one side of the display screen body 1, and connected to the display screen for plugging in various lines. The specific structure and connection method of the display screen and the terminal block 3 can be referred to in the prior art of vehicle-mounted display screens, which are common prior art, so they are not described in detail here. The terminal block 3 has a line interface 32 on its side wall, and a rectangular plate 31 is fixed to one side wall of the terminal block 3. The inner side of the rectangular plate 31 has a rotating groove 311, a circular groove, the opening size of which is smaller than the maximum inner diameter of the groove. A support frame 5 is inserted into one side of the rectangular plate 31. For details, please refer to the attached document. Figure 1 Appendix Figure 2 Appendix Figure 4 and attached Figure 5 The support frame 5 includes a fixed cylinder 51, a movable opening 52, a movable column 53, and a rotating ball 54. The fixed cylinder 51 is fixed to the external vehicle frame, and its fixed position can be flexibly adjusted according to different vehicles. One end of the fixed cylinder 51 is provided with a movable opening 52, and a movable column 53 is inserted into the inner side of the fixed cylinder 51, passing through the movable opening 52. The movable column 53 can move inside the fixed cylinder 51. One end of the movable column 53 is fixed with a friction plate 55, which is located inside the fixed cylinder 51. The friction plate 55 is made of elastic material and can provide friction positioning for the moved movable column 53. One end of the movable column 53 is fixed with a rotating ball 54, which is located inside the rotating groove 311. The rotating ball 54 is made of elastic material and can provide a certain amount of friction with the inner wall of the rotating groove 311, so that the display screen can stably maintain its rotation. To prevent the display screen from easily sliding (elastic protrusions can even be added to the outer wall of the rotating ball 54 to increase friction, but since this is a common technical method, it will not be elaborated on here), the rotation angle of the display screen is determined by the diameter of the moving column 53. The smaller the diameter, the larger the rotation angle. Different diameter moving columns 53 can be selected according to actual needs. The display screen body 1 has a mounting frame 2 on one side, which is the external structure for mounting the display screen and is located in front of the driver and passenger seats. This solution sets up a display screen that can be pulled outward and rotated after being pulled, so that the orientation of the display screen can be adjusted according to the operating needs of the driver or passenger, making it easier for the operator to look directly at the display screen and improving the convenience and comfort of observation or operation.

[0024] Reference Figure 2 and Figure 5As shown, specifically, a telescopic sleeve 4 is fixed to the side wall of the display body 1. The telescopic sleeve 4 is located on the outside of the wiring board 3 and can be elastically stretched and compressed. One end of the telescopic sleeve 4 is fixedly connected to the inside of the mounting frame 2. A fixing washer 41 is fixed to one end of the telescopic sleeve 4. The fixing washer 41 is fixed on the inner wall of one side of the moving groove 22. When the display is pulled outward, the telescopic sleeve 4 can protect the outside of the display and prevent some liquids or debris from entering the wiring area. Example

[0025] In another embodiment of this solution, refer to Figure 1 , Figure 3 and Figure 6 As shown, specifically, a slot 21 is provided on one side wall of the mounting frame 2, and a connecting frame 11 is fixed on the outer side of the display body 1. The connecting frame 11 is located on one side of the slot 21, and the size of the connecting frame 11 is adapted to the inner size of the slot 21. When the display is reset, the connecting frame 11 can be engaged in the inner side of the slot 21. At the same time, when the display is pulled outward, tools such as mobile phone holders can be easily clamped by the connecting frame 11, improving the practicality of the display device. Example

[0026] In another embodiment of this solution, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, specifically, the inner side of the mounting frame 2 is provided with a movable groove 22, and a support cylinder 23 is fixed inside the movable groove 22. One end of the telescopic sleeve 4 is fixedly connected to the inner side of the movable groove 22. The telescopic sleeve 4 is located outside the support cylinder 23. The support frame 5 passes through the support cylinder 23. A positioning insert 33 is symmetrically fixed on one side wall of the wiring board 3. A slot 231 is symmetrically provided on one side wall of the support cylinder 23. The positioning insert 33 is inserted into the inner side of the slot 231. When the display screen is not in use, the display screen can be straightened and pushed backward so that the positioning insert 33 is aligned and inserted into the inner side of the slot 231, thereby achieving stable positioning of the display screen, avoiding shaking of the display screen, facilitating storage of the display screen, and preventing it from always protruding and easily damaged.

[0027] The working principle and usage process of this utility model are as follows: When using the vehicle display screen, the driver or passenger can pull the display screen outward as needed, so that the movable column 53 on the support frame 5 moves inside the fixed cylinder 51. Through the support of the movable column 53 by the fixed cylinder 51, the display screen can still be stably supported after being extended. After the display screen is pulled out, the operator can rotate the display screen at a certain angle, so that the rotating ball 54 rotates inside the rotating groove 311, making it easier for the operator to look directly at the display screen when operating or viewing it. This avoids the situation where the operator cannot look directly at the display screen even if they turn their head when using a conventionally fixed display screen, thus improving the comfort of use. When the display screen is not in use, it can be straightened and pushed backward, so that the connecting frame 11 on the outer side of the display screen engages with the slot 21 on the mounting frame 2, and the positioning plug 33 on the side of the wiring board 3 is inserted into the slot 231 on the mounting frame 2, thus achieving stable storage of the display screen and convenient operation.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
