Description

Technical Field

[0001] This utility model belongs to the field of automotive central control screen technology, and in particular relates to a rotating screen structure for automotive central control. Background Technology

[0002] With the increasing intelligence of automobiles, the functional integration and interactive requirements of in-vehicle infotainment systems have significantly increased. Rotatable center console screens, due to their ability to flexibly adapt to both landscape and portrait display modes, have become an important feature for improving interior space utilization and ease of operation. However, current technologies still face many technical bottlenecks in implementing screen rotation functionality: 1. Traditional rotating mechanisms often use linear guides or simple hinge structures. When the screen changes from horizontal to vertical, its starting point needs to move tangentially along the direction of rotation. If the trajectory is not planned properly, the lower edge of the screen may exceed the original space range, causing mechanical interference with the dashboard, shift mechanism and other surrounding components, or even causing damage to the appearance.

[0003] 2. Conventional gear transmissions have backlash, which can cause slight wobbling during screen rotation. This not only reduces the feel of operation but also causes screen shaking when hovering, affecting driving safety and user experience.

[0004] Therefore, how to solve the above-mentioned technical problems has become a problem that technicians in this field need to solve. Summary of the Invention

[0005] The purpose of this invention is to provide a rotating screen structure for automotive central control that can completely solve the shortcomings of the prior art.

[0006] The objective of this utility model is achieved through the following technical solution: A rotating central control screen structure for automobiles includes a mounting base plate and a central control screen. The mounting base plate has an elliptical arc opening and a guide rod is vertically fixed thereon. A slider is slidably fitted on the guide rod. A gear is engaged with the elliptical arc opening. The gear is hinged to one end of a connecting rod, and the other end of the connecting rod is hinged to the slider. The back of the central control screen is connected to the connecting rod.

[0007] Preferably, the guide rod surface is knurled.

[0008] Preferably, the gear is a backlash-free gear.

[0009] Preferably, the backlash-free gear includes a first gear, a second gear, and a plate-shaped elastic element. The first gear and the second gear are mounted on the same bearing and have a phase difference in the circumferential direction. The first gear and the second gear have corresponding holes, and the plate-shaped elastic element is disposed in the holes. One end of the plate-shaped elastic element is connected to the first gear, and the other end is connected to the second gear.

[0010] Preferably, the connecting rod is provided with two connecting posts, and a mating hole is provided on the back of the central control screen, with the connecting posts and the mating hole being interference fit.

[0011] Preferably, the angle between the diagonal of the central control screen and the positive X-axis in the Cartesian coordinate system is always greater than the angle between the diagonal and the long side of the central control screen.

[0012] Preferably, the mounting base plate has a guide groove corresponding to the elliptical arc opening, and a guide block is provided on the back of the central control screen, with the guide block slidingly engaged in the guide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. It can realize the rotation function of the car's central control screen and effectively avoid the problem of downward interference caused by tangential movement during the screen rotation process; 2. Adopting a backlash-free gear structure, through the phase difference design of the two gears and the pre-tightening effect of the elastic element, the gear meshing gap is completely eliminated, so that the screen rotates without slipping and remains stable when hovering, significantly improving the operating feel and reliability; 3. The knurling treatment on the guide rod surface effectively prevents tilting caused by vibration during screen rotation; at the same time, the sliding fit between the guide groove on the mounting base and the guide block on the back of the screen further constrains the movement trajectory of the screen, ensuring the accuracy and smoothness of the rotation.

[0016] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0017] like Figures 1 to 8 As shown, a rotating central control screen structure for automobiles includes a mounting base plate 1 and a central control screen 2. The mounting base plate 1 has an elliptical arc opening 3 and a guide rod 4 is vertically fixed thereon. A slider 5 is slidably fitted on the guide rod 4. A gear 6 is engaged on the elliptical arc opening 3. The gear 6 is hinged to one end of a connecting rod 7, and the other end of the connecting rod 7 is hinged to the slider 5. The back of the central control screen 2 is connected to the connecting rod 7.

[0018] In this embodiment, the mounting base 1 and the central control screen 2 are overlapped. The mounting base 1 is made of high-strength aluminum alloy sheet. The lower edge of the elliptical arc opening 3 is provided with meshing teeth 8 along the elliptical arc to mesh with gears 6. In the initial position, the mounting base 1 and the central control screen 2 are completely overlapped, and the center line of the central control screen 2 is parallel to the axis of the guide rod 4, ensuring rotational balance. Specifically, when the central control screen 2 is in landscape mode, the axis of the guide rod 4 is parallel to the center line of the length direction of the central control screen 2; when the central control screen 2 is in portrait mode, the axis of the guide rod 4 is parallel to the center line of the width direction of the central control screen 2.

[0019] In this embodiment, the guide rod 4 has knurling 9 on its surface. The knurling 9 is composed of multiple grooves arranged along the axial direction of the guide rod. This structural design can effectively prevent tilting caused by vibration during the rotation of the central control screen 2.

[0020] In this embodiment, gear 6 is a backlash-free gear. This backlash-free gear includes a first gear 61, a second gear 62, and a plate-shaped elastic element 63. The first gear 61 and the second gear 62 are mounted on the same bearing 64 and have a 5° phase difference in the circumferential direction. The first gear 61 and the second gear 62 are made of carburized and quenched steel to improve wear resistance.

[0021] Rectangular holes 65 are correspondingly formed on the first gear 61 and the second gear 62. A plate-shaped elastic element 63 is disposed in the rectangular hole 65, with one end of the plate-shaped elastic element 63 connected to the first gear 61 and the other end connected to the second gear 62. The plate-shaped elastic element 63 is made of spring steel sheet, which eliminates gear meshing gap through elastic deformation, so that the central control screen 2 does not move during rotation and remains stable when hovering, significantly improving the operation feel and reliability.

[0022] In this embodiment, the connecting rod 7 is provided with two connecting posts 10, and the back of the central control screen 2 is provided with corresponding mating holes. The connecting posts 10 are interference-fitted with the mating holes and are cured with epoxy resin to form a rigid connection.

[0023] See Figure 8 and Figure 9 In this embodiment, the angle θ between the diagonal of the central control screen 2 and the positive X-axis in the Cartesian coordinate system is always greater than the angle α between the diagonal and the long side of the central control screen 2, i.e., θ>α. This ensures that during the rotation of the central control screen 2 from landscape to portrait or vice versa, the bottom of the central control screen 2 will not exceed the bottom edge of the mounting base 1, satisfying the condition of no interference in the motion trajectory. If θ<α, the bottom of the central control screen 2 will exceed the bottom edge of the mounting base 1, causing interference with other components.

[0024] In this embodiment, a guide groove 11 is provided on the mounting base plate 1 corresponding to the elliptical arc opening 3, and a guide block is provided on the back of the central control screen 2, which slides in the guide groove 11. This structural design further constrains the movement trajectory of the central control screen 2, ensuring the accuracy and smoothness of the rotation action.

[0025] In simulated bumpy road tests, the knurled texture on the guide rod 4 provides a damping torque of ≥2 N·m, effectively suppressing the tilting phenomenon of the central control screen 2 caused by resonance. The measured gear transmission backlash is ≤0.01°, reduced by more than 90% compared to traditional gears, and the screen's wobbling amplitude when hovering is <0.1°. After 100,000 reciprocating rotation tests, the fatigue deformation of the elastic element is <0.02mm, maintaining effective preload. To address the space limitations of small vehicle dashboards, the mounting base thickness is reduced to 8mm, and the elliptical arc opening is reduced to a major axis of 100mm and a minor axis of 60mm, while maintaining the relative positional relationship between the guide rod 4 and the gear 6. When the central control screen 2 rotates to a specific angle (e.g., 30°, 60°), the Hall sensor is triggered, and the vehicle system automatically switches the display interface ratio.

[0026] Work process: In the initial state, the central control screen 2 is completely overlapped with the mounting base plate 1. The central control screen 2 is pushed upward, thereby causing the slider 5 to slide on the guide rod 4. The gear 6 moves from one end of the elliptical arc opening 3 to the other end, thus completing the conversion from horizontal to vertical screen. Throughout the process, the bottom of the central control screen 2 will not exceed the bottom edge of the mounting base plate 1.
