A single-wheel controlled four-way rotating screen

Abstract

The present invention discloses a single-wheel controlled four-directional rotating screen, comprising a screen, a rotating shaft, a direction-changing wheel, and a lifting guide rail. The sidewalls and sides of the direction-changing wheel are provided with inner and outer guide rails, respectively. When the direction-changing wheel rotates, the connecting column and the lifting guide rail, which slide in contact with the inner and outer guide rails, respectively, produce different screen rotation effects depending on whether they are located in arc segments or curve segments. This allows the screen to rotate in four directions controlled by a single wheel, resulting in a simple overall structure, reduced installation space for a multi-directional rotating screen, and lower production costs.

Description

Technical Field

[0001] The present invention relates to the field of electric vehicle electronic screen technology, and more specifically, to a single-wheel controlled four-direction rotating screen. Background Art

[0002] As consumer demand for automotive electronics continues to increase, the number of central control screens and viewing screens is increasing. To enhance the viewing experience, the screen's height and angle need to be adjusted. Many car models now use rotating screen mechanisms. However, rotating the screen in one plane typically requires a transmission mechanism to achieve multiple angles. This typically requires a complex structure, coupled with various controllers for automatic control. This results in high overall costs, large size, and difficulty repairing any malfunctions. With the increasing functionality of today's vehicles, the demand for precision and compactness of various components is also increasing. Therefore, a device that can achieve multiple angles of screen rotation with a single transmission mechanism is needed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the existing control of four-way rotation of the screen requires at least two motors. A single-wheel controlled four-way rotating screen is provided, which can realize the four-way rotation of the screen controlled by a single wheel. The overall device has a simple structure, a smaller size and a lower production cost.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0019] like Figure 1-Figure 3As shown, a single-wheel controlled four-way rotating screen 1 includes a screen 1, a connecting column 2 is fixed to the lower side of the screen 1, the connecting column 2 is connected to the rotating shaft 3, a shell 4 is provided under the rotating shaft 3, a changing wheel 5 is provided in the shell 4, outer tracks 6 are provided on both sides of the changing wheel 5, an inner guide rail is provided on the side wall of the changing wheel 5, a lifting guide rail 8 is vertically provided on the outer guide rail, the top end of the lifting guide rail 8 moves along the outer guide rail, and a bottom plate is fixed to the bottom end of the lifting guide rail 8, a sliding shaft 9 is fixed on the lower side of the rotating shaft 3, and the top end of the sliding shaft 9 moves along the inner guide rail, the inner guide rail includes an inner arc segment 71 and an inner curve segment 72, the outer guide rail includes an outer arc segment and an outer curve segment 62, the sum of the degrees of the inner arc segment 71 and the outer arc segment is 360 degrees, a rack is provided on the side wall of the changing wheel 5, and a meshing gear 10 is provided below the changing wheel 5, and the gear 10 is connected to a power device. The screen 1 needs to be able to move up and down, and rotate left and right in four directions. Its direction is controlled by the movement of the rotating shaft 3 connected below. The sliding shaft 9 below the rotating shaft 3 is slidably connected to the inner guide rail, and the direction of movement can be changed according to its displacement. The direction-changing wheel 5 rotates under the action of the power device and the gear 10. At this time, the lifting guide rail 8 slides on the outer rail 6, and the sliding shaft 9 slides on the inner guide rail. When the lifting guide rail 8 slides on the outer arc section, the sliding shaft 9 slides on the inner curve section 72. At this time, the direction-changing wheel 5 does not produce any displacement in height, and the connecting shaft will be offset in the left and right directions, realizing the left and right movement of the screen 1; when the lifting guide rail 8 slides on the outer curve section 62, the sliding shaft 9 slides on the inner arc section 71. At this time, the direction-changing wheel 5 is displaced in the vertical direction, driving the sliding shaft 9 and the rotating shaft 3 to change in height, without any offset to the left and right, realizing the left and right and vertical movement of the screen 1.

[0020] In one embodiment, the lifting guide rail 8 is provided with a limiting slot 81, and the housing 4 is provided with a connecting block 82. The connecting block 82 is inserted into the limiting slot 81 and moves up and down along the limiting slot 81 as the housing 4 moves. Limiting blocks 83 are provided on both sides of the housing 4, and the lifting guide rail 8 is inserted into the limiting blocks 83. As the housing 4 moves up and down with the direction-changing wheel 5, the connecting block 82 slides in the limiting slot 81, thereby enhancing the reliability of the up and down motion trajectory. The top end of the lifting guide rail 8 slides on the outer guide rail and is inserted into the limiting block 83, which can improve the stability of the entire device.

[0021] In one embodiment, a contact head is vertically mounted at the top of the lifting rail 8. The contact head has a spherical tip and can slide within the outer rail. The sliding shaft 9 has a spherical tip and can slide within the inner rail. The contact head and sliding shaft 9 slide within the outer and inner rails, respectively, reducing friction and improving movement sensitivity, thereby enhancing the sensitivity of the screen 1 rotation.

[0022] In one embodiment, the rotating shaft 3 is rotatably mounted on the top of the housing 4, and two connecting posts 2 are fixedly connected to either side of the rotating shaft 3. The connecting posts 2 are arranged on both sides of the rotating shaft 3 to improve the stability between the rotating shaft 3 and the screen 1. The rotation of the rotating shaft 3 drives the screen 1 to rotate left and right, and the rotating shaft 3 is mounted on the housing 4 to improve the sensitivity of the movement.

[0023] In one embodiment, during the rotation of the changing wheel 5, when the top end of the lifting guide rail 8 rotates on the outer arc segment, the sliding shaft 9 slides on the inner curve; when the top end of the lifting guide rail 8 rotates on the outer curve segment 62, the sliding shaft 9 slides on the inner arc segment.

[0024] In one embodiment, the inner arc segment 71 and the outer arc segment are concentric with the turning wheel 5, while the inner curved segment 72 and the outer curved segment 62 are arcs that are not concentric with the turning wheel 5. The key to achieving four-way motion of the screen 1 lies in that when the lifting guide rail 8 slides in the outer arc segment, the screen 1 does not move up or down; when the sliding shaft 9 slides in the inner arc segment 71, the screen 1 does not rotate left or right. Setting the center positions of the arc and curved segments enables corresponding displacement changes.

[0025] In one embodiment, after the screen 1 is moved up and down and then adjusted left or right for use, the gear 10 within the housing 4 rotates the turning wheel 5. At this point, the lifting guide rail 8 slides within the outer curved section 62, and the sliding shaft 9 slides within the inner arc section 71. As the lifting guide rail 8 slides, it drives the housing 4 up and down, thereby achieving up and down movement of the screen 1. When the lifting guide rail 8 enters the outer arc section, the screen 1 ends its up and down movement. Simultaneously, the sliding shaft 9 slides to the inner curved section 72, shifting left and right along the trajectory of the inner curved section 72, driving the connected rotating shaft 3 to rotate, thereby achieving left and right rotation of the screen 1. The overall structure is simple, with the core design of the inner and outer rails 7 and 6. The control system of the entire device controls the rotation direction and speed of the gear 10, thereby driving the turning wheel 5. During the rotation of the turning wheel 5, the lifting guide rail 8 and sliding shaft 9 slide on the outer and inner rails, respectively. The position and speed of their sliding motion drive the rotation of the screen 1 and control the rotation speed.
