Description

Technical Field

[0001] This invention relates to the field of vehicle display technology, and in particular to a multi-degree-of-freedom electric rotating screen for automobiles. Background Technology

[0002] Cars are a common means of transportation, and with economic development, they have become an essential mode of travel for every household. Since their introduction to automobiles, displays have been continuously updated and upgraded. Initially, small screens could only be used for simple displays; with the advent of touch-screen interfaces, they can now serve as integrated interfaces for display and control.

[0003] In recent years, driven by the trend of intelligent in-vehicle products, there has been a greater demand for the installation structure of in-vehicle displays. In-vehicle displays can be electrically driven to rotate or move in the interior space, providing practical and comfortable operation. At the same time, they can highlight the intelligent features of the in-vehicle display and improve the overall intelligent image of the car. Therefore, more and more car manufacturers have plans and needs for such products.

[0004] Some existing technologies also include vehicle display screen mounting structures that enable rotation. For example, Chinese Patent Publication No. CN217347684 U discloses a multi-directional rotation structure for a vehicle display screen and a car. The multi-directional rotation structure includes a first rotation unit and a second rotation unit. The first rotation unit is connected to the display screen to drive it to rotate around a first axis; the second rotation unit is connected to the first rotation unit to drive it to rotate around a second axis; wherein the first axis is perpendicular to the second axis. While this solution combines the mutually perpendicular first and second rotation units, allowing the vehicle display screen to rotate simultaneously in both left-right and up-down directions, the rotation axes are not at the same point, making operation complex and the function relatively limited. Furthermore, it is prone to interference with other structures during rotation, thus restricting the use of the rotation function.

[0005] Therefore, this application is hereby submitted. Summary of the Invention

[0006] In view of this, the present invention aims to propose a multi-degree-of-freedom electric rotating screen for automobiles to solve the problems of limited rotational movement and inconvenient operation of existing in-vehicle displays.

[0007] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

The first gear portion meshes with the second drive motor assembly for transmission, and the first hinge mounting portion is hingedly connected to the screen mounting plate.

[0015] Furthermore, the vertical rotating gear assembly includes a second gear portion, a second hinge portion, and a second hinge mounting portion. The second gear portion and the second hinge mounting portion are respectively disposed on opposite sides of the second hinge portion.

[0016] Furthermore, the screen mounting plate includes a mounting plate body, on which a vertical hinge pin connecting unit and a horizontal hinge pin connecting unit are provided. The vertical hinge pin connecting unit is located on the vertical central axis of the mounting plate body, and the horizontal hinge pin connecting unit is located on the horizontal central axis of the mounting plate body. The horizontal hinge pin connecting unit is hinged to the first hinge mounting part through a horizontal hinge shaft, and the vertical hinge pin connecting unit is hinged to the second hinge mounting part through a vertical hinge shaft.

[0017] Furthermore, the transmission structure between the first gear section and the second drive motor assembly is a worm gear transmission structure, the transmission structure between the second gear section and the third drive motor assembly is a worm gear transmission structure, and the first gear section and the second gear section are sector gear sections.

[0018] Furthermore, the second drive motor assembly and the screen mounting plate are arranged at an inclined angle in the horizontal direction, and the third drive motor assembly and the screen mounting plate are arranged at an inclined angle in the vertical direction.

[0019] Furthermore, the telescopic mechanism assembly includes a first drive motor assembly, which drives the connecting base to slide in the back and forth direction through a transmission screw and a screw nut, and the connecting base is fixedly connected to the screen support.

[0020] Furthermore, a first gear device is provided at the end of the transmission screw. The first gear device meshes with the transmission shaft of the first drive motor assembly. A screw nut is sleeved on the outside of the transmission screw. The screw nut is threadedly connected to the transmission screw. The screw nut is integrated with the connecting base through a support tube. During the forward or reverse rotation of the first gear device driven by the first drive motor assembly, the transmission screw drives the screw nut, support tube, and connecting base to slide forward or backward as a whole.

[0021] Furthermore, the transmission lead screw is connected to the housing assembly outside the first drive motor assembly via a limiting bearing, and a sliding cover is provided on the side of the connecting base near the first gear device.

At the same time, the telescopic mechanism component drives the screen support base equipped with the horizontal rotating component and the vertical rotating component to move in the front and back directions, making it suitable for different installation requirements and space constraints.

[0039] Example 1

[0040] like Figures 1-6 As shown, this invention discloses a multi-degree-of-freedom electric rotating screen for automobiles, comprising:

[0041] Screen mounting plate 15 is used to mount the display assembly;

[0042] The horizontal rotation component includes a second drive motor assembly 7 and a horizontal rotation gear assembly 10. The horizontal rotation gear assembly 10 is hinged to the screen mounting plate 15. The second drive motor assembly 7 drives the screen mounting plate 15 to rotate horizontally along the vertical central axis through the horizontal rotation gear assembly 10.

[0043] The vertical rotation assembly includes a third drive motor assembly 12 and a vertical rotation gear assembly 11. The vertical rotation gear assembly 11 is hinged to the screen mounting plate 15. The third drive motor assembly 12 drives the screen mounting plate 15 to rotate vertically along the horizontal central axis through the vertical rotation gear assembly 11.

[0044] Screen support 6 is used to mount the second drive motor assembly 7 and the third drive motor assembly 12;

[0045] The telescopic mechanism assembly includes a first drive motor assembly 1 for driving the screen support base 6 to move horizontally in the front-rear direction.

[0046] This invention discloses a multi-degree-of-freedom electric rotating screen for automobiles. Through a telescopic mechanism, a horizontal rotation component, and a vertical rotation component, the screen mounting plate 15 achieves sliding motion in the front-to-back direction and rotation in the horizontal (left-right) and vertical (up-down) directions. The horizontal and vertical rotation components directly drive the screen mounting plate 15 to rotate horizontally along the vertical central axis and vertically along the horizontal central axis. This allows the screen mounting plate 15 to converge at a single point during both horizontal and vertical rotations, facilitating rotation control of the vehicle display screen. Simultaneously, both the horizontal and vertical rotation components are fixed to the screen support 6. The telescopic mechanism drives the screen support 6 and the screen mounting plate 15 to slide together in the front-to-back direction, achieving reliable adjustment of the vehicle display screen's movement in three dimensions. This avoids interference from other structures that could restrict the rotational movement of the vehicle display screen, improving the reliability of its rotation.

[0047] The multi-degree-of-freedom electric rotating screen for automobiles described in this invention, through multi-dimensional motion adjustment, rotation convergence at a single point, and a design that avoids motion restrictions, facilitates user operation, provides a better user experience, and enables the in-vehicle display screen to be flexibly adjusted and rotated in the vehicle to meet the needs of different usage scenarios. It is highly reliable and adaptable.

[0048] As a preferred example of the present invention, the rotation direction of the horizontal rotating gear assembly 10 is perpendicular to the rotation direction of the vertical rotating gear assembly 11.

[0049] This setup uses two drive motor assemblies and corresponding rotary gear assemblies to drive the screen mounting plate 15 to rotate independently in the horizontal or vertical directions, allowing users to adjust the angle and orientation of the vehicle display screen as needed, thus improving user experience and convenience.

[0050] As a preferred example of the present invention, the horizontal rotating gear assembly 10 includes a first gear portion 1001, a first hinge portion 1002, and a first hinge mounting portion 1003. The first gear portion 1001 and the first hinge mounting portion 1003 are respectively disposed on opposite sides of the first hinge portion 1002. The first gear portion 1001 meshes with the second drive motor assembly 7 for transmission, and the first hinge mounting portion 1003 is hinged to the screen mounting plate 15.

[0051] This design discloses a structure for a horizontal rotating gear assembly 10, which ensures the reliability of the screen mounting plate 15 being driven horizontally by the second drive motor assembly 7, while not affecting the operation of the vertical rotating assembly. It separates the gear transmission and the hinge connection, providing more operational flexibility and controllability, and allowing users to freely adjust the angle and orientation of the vehicle display screen as needed.

[0052] As a preferred example of the present invention, the vertical rotating gear assembly 11 includes a second gear portion 1101, a second hinge portion 1102, and a second hinge mounting portion 1103. The second gear portion 1101 and the second hinge mounting portion 1103 are respectively disposed on opposite sides of the second hinge portion 1102. The second gear portion 1101 meshes with the third drive motor assembly 12 for transmission, and the second hinge mounting portion 1103 is hinged to the screen mounting plate 15.

[0053] This design discloses a structure of a vertical rotating gear assembly 11. The transmission structure of the vertical rotating gear assembly 11 is similar to that of the horizontal rotating gear assembly 10. It has a simple structure, fewer parts, and reliable operation, which improves the convenience and reliability of users adjusting the angle and direction of the vehicle display screen.

[0054] As a preferred example of the present invention, the screen mounting plate 15 includes a mounting plate body 1501, on which a vertical hinge pin connecting unit 1502 and a horizontal hinge pin connecting unit 1503 are provided. The vertical hinge pin connecting unit 1502 is disposed on the vertical central axis of the mounting plate body 1501, and the horizontal hinge pin connecting unit 1503 is disposed on the horizontal central axis of the mounting plate body 1501. The horizontal hinge pin connecting unit 1503 is hinged to the first hinge mounting part 1003 through a horizontal hinge shaft 21, and the vertical hinge pin connecting unit 1502 is hinged to the second hinge mounting part 1103 through a vertical hinge shaft 20. As an example of this application, the vertical hinge column connection unit 1502 and the horizontal hinge column connection unit 1503 are disposed on the mounting plate 1501 at a position close to the center. As an example, the vertical hinge column connection unit 1502 is disposed at the center of the vertical central axis on the mounting plate 1501, and the horizontal hinge column connection unit 1503 is disposed on one side of the vertical hinge column connection unit 1502.

[0055] In use, when the second drive motor assembly 7 drives the horizontal rotating gear assembly 10 to rotate horizontally, the third drive motor assembly 12 is hinged to the screen mounting plate 15 along the vertical direction via the vertical rotating gear assembly 11. This causes the second hinge portion 1102 of the vertical rotating gear assembly 11 to adapt to the horizontal rotation of the screen mounting plate 15, and the second gear portion 1101 of the vertical rotating gear assembly 11 remains engaged with the third drive motor assembly 12. Similarly, when the third drive motor assembly 12 drives the vertical rotating gear assembly 11 to rotate vertically, the second drive motor assembly 7 is hinged to the screen mounting plate 15 along the horizontal direction via the horizontal rotating gear assembly 10. This causes the first gear portion 1001 on the horizontal rotating gear assembly 10 to remain engaged with the second drive motor assembly 7 during vertical rotation of the screen mounting plate 15.

[0056] Through the above settings, the screen mounting plate 15 can achieve multi-axis adaptive movement when rotating horizontally or vertically, which improves the flexibility and reliability of the installation structure. At the same time, the setting of the hinge column connection unit enables the rotational movement to adapt to changes in different directions and maintain a stable meshing state, thereby improving the reliability and adaptability of the rotation control of the vehicle display screen.

[0057] As a preferred embodiment of the present invention, the second drive motor assembly 7 and the screen mounting plate 15 are arranged at an inclined angle in the horizontal direction, and the third drive motor assembly 12 and the screen mounting plate 15 are arranged at an inclined angle in the vertical direction. Preferably, the value of the above-mentioned angle is in the range of 15° to 75°, and more preferably 30° to 60°.

[0058] This design optimizes the structure of the horizontal and vertical rotating components in the vehicle display installation structure, resulting in a compact transmission structure that reduces the space it occupies and improves the applicability of the multi-degree-of-freedom electric rotating screen for automobiles described in this invention.

[0059] As a preferred example of the present invention, the first gear section 1001 and the second gear section 1101 are sector teeth. The transmission structure between the first gear section 1001 and the second drive motor assembly 7 is a worm gear transmission structure, and the transmission structure between the second gear section 1101 and the third drive motor assembly 12 is a worm gear transmission structure. By setting the first gear section 1001 and the second gear section 1101 as sector teeth, on the one hand, energy loss during transmission is reduced, transmission efficiency is improved, impact and noise between gears are reduced, and smooth transmission operation is achieved. On the other hand, the above transmission method also has the advantages of a large transmission ratio, good self-locking performance, small space occupation, and ensures the reliability and control accuracy of the rotational movement of the screen mounting plate.

[0060] As a preferred example of the present invention, a first gear cover plate 8 is provided on the second drive motor assembly 7. The first gear cover plate 8 is located at the meshing point of the worm and the first gear portion 1001 on the second drive motor assembly 7, and the first gear cover plate 8 is arranged horizontally. A second gear cover plate 13 is provided on the third drive motor assembly 12. The second gear cover plate 13 is located at the meshing point of the worm and the upper second gear portion 1101 on the third drive motor assembly 12, and the second gear cover plate 13 is arranged vertically.

[0061] This design effectively protects the meshing parts of the worm and gear, preventing dust and debris from entering, reducing friction, wear, and malfunctions, and improving the reliability and stability of the transmission system.

[0062] As a preferred example of the present invention, the telescopic mechanism assembly includes a first drive motor assembly 1, which drives the connecting base 19 to slide in the front and back direction through the transmission screw 3 and the screw nut 4. The connecting base 19 is fixedly connected to the screen support 6.

[0063] This design discloses a method for moving the screen support 6 in the forward and backward directions, making it suitable for different installation needs and space constraints, while ensuring the safety and reliability of the vehicle display screen during movement.

[0064] As a preferred example of the present invention, a first gear device 2 is provided at the end of the transmission screw 3. The first gear device 2 meshes with the transmission shaft of the first drive motor assembly 1. A screw nut 4 is sleeved on the outside of the transmission screw 3. The screw nut 4 is threadedly connected to the transmission screw 3. The screw nut 4 is connected to the connecting base 19 as a whole through the support tube 5. When the first drive motor assembly 1 drives the first gear device 2 to rotate in the forward or reverse direction, the transmission screw 3 drives the screw nut 4, the support tube 5 and the connecting base 19 to slide forward or backward as a whole.

[0065] This setup is compact and reliable in its transmission, while providing stable support and fixation to ensure the stability and reliability of the display screen during movement and use, making the installation and adjustment of the vehicle-mounted display screen more convenient and flexible.

[0066] As a preferred example of the present invention, the transmission lead screw 3 is connected to the housing assembly outside the first drive motor assembly 1 via a limiting bearing 23, and a sliding cover 22 is provided on the side of the connecting base 19 near the first gear device 2. The sliding cover 22 moves integrally with the connecting base 19 and limits the stroke of the connecting base 19.

[0067] This setup allows for precise control and limitation of the movement and stroke of the transmission screw 3 and the connecting base 19, ensuring that the movement stroke of the telescopic mechanism is within a safe and reliable range. It features a simple structure, reliable operation, and improves the service life and reliability of the entire telescopic mechanism.

[0068] As a preferred example of the present invention, the housing assembly includes a first outer shell 16, a second outer shell 17, and a connecting sleeve 18. The first outer shell 16 and the second outer shell 17 wrap around opposite sides of the first drive motor assembly 1, and an enclosure portion is formed on the first outer shell 16 at the meshing point between the first drive motor assembly 1 and the first gear device 2. The connecting sleeve 18 is disposed on the outer side of the sliding cover 22. Preferably, the connecting sleeve 18 is integrally formed with the second outer shell 17.

[0069] By setting a housing assembly on the outside of the first drive motor assembly 1 and the telescopic structure of the lead screw drive, the telescopic structure, drive motor and key components are protected and encapsulated, effectively preventing external debris, dust or other substances from entering the telescopic mechanism transmission assembly, protecting the internal mechanism from the influence and damage of the external environment, and improving the safety and reliability of the telescopic mechanism assembly.

[0070] As a preferred example of the present invention, a first connecting rod assembly 9 and a second connecting rod assembly 14 are respectively provided on opposite sides of the screen support 6 in the horizontal direction. Both the first connecting rod assembly 9 and the second connecting rod assembly 14 include multiple connecting rods. As an example of this application, the first connecting rod assembly 9 and the second connecting rod assembly 14 are used to connect the screen support 6 to other fixed structures. This arrangement further ensures the stability of the connection of the screen support 6 and the reliability of its sliding in the front-back direction.

[0071] The multi-degree-of-freedom electric rotating screen for automobiles described in this invention achieves telescopic and rotational functions in three directions through three drive motors. These telescopic and rotational functions are independently controlled and complementary. During rotation, when either the horizontal or vertical rotating component acts as a transmission gear, the other gear can remain in its absolute position, or both gears can rotate simultaneously. This improves the convenience and reliability of users adjusting the angle and direction of the in-vehicle display screen. Simultaneously, the telescopic mechanism drives the screen support 6, which houses the horizontal and vertical rotating components, to move forward and backward, making it suitable for various installation requirements and space constraints. The ingenious structure and reliable operation enable reliable adjustment of the in-vehicle display screen's movement in three dimensions.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
