Description

Technical Field

[0001] This utility model relates to the field of vehicle display screens, and specifically discloses a mechanism for enabling the display screen to slide left and right. Background Technology

[0002] Cars are a common means of transportation in people's lives today. As the electrification, intelligence, connectivity and sharing of cars are moving from "concept" to practical application, people's needs for cars are no longer limited to transportation tools, but also include navigation, consumption, entertainment, interaction and other travel-related needs, making them another "intelligent center" in life.

[0003] In the automotive display industry, adjustable-angle displays are becoming increasingly common, such as tilting screens and flip screens. However, because the central control screen cannot be moved, both the driver and passenger need to twist their bodies to view it at an angle, resulting in a poor experience and failing to meet customers' need for direct viewing.

[0004] Currently available sliding mechanisms for displays on the market suffer from problems such as jamming, shaking, and abnormal noise during operation. These issues arise due to their complex structure, low efficiency, and the tendency for the lead screw and nut to wear out easily. To address the shortcomings of existing technology, it is necessary to design a stable and simple mechanism to solve these problems. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a mechanism for realizing the left and right sliding of the display screen, so as to solve the technical problem of how to make the display screen slide stably.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mechanism for enabling left and right sliding of a display screen includes a mechanism frame, a drive unit, and a transmission unit. Both the drive unit and the transmission unit are disposed within the mechanism frame. The drive unit includes a motor, and the transmission unit includes a synchronous belt, a synchronous pulley, a driven pulley, a guide rail, and a slider. The motor is connected to the synchronous pulley, the synchronous belt is wound around the synchronous pulley and the driven pulley, the slider is slidably connected to the guide rail, the slider is fixedly connected to the synchronous belt, and the slider is connected to the display screen.

[0008] Optionally, the drive unit further includes a reduction gearbox, the motor is connected to the reduction gearbox, and the reduction gearbox is connected to the synchronous pulley.

[0009] Optionally, the transmission unit further includes a fixed block, which is connected to the timing belt, and the slider is then connected to the fixed block.

[0010] Optionally, the transmission unit further includes a mounting bracket, the slider is connected to the mounting bracket, and the mounting bracket is then connected to the display screen.

[0011] Optionally, the mechanism frame includes a front shell, a middle frame, and a rear cover; the rear cover is connected to the middle frame, and the front shell is connected to the middle frame.

[0012] The working principle and beneficial effects of this solution are as follows:

[0013] Sliding process: The motor drives the gearbox to work, and the gearbox drives the synchronous pulley to rotate; the synchronous pulley drives the synchronous belt, fixed block, and slider to move. Since the mounting bracket is fixed on the slider, the display screen follows the synchronous belt.

[0014] Beneficial effects: The drive mechanism is simpler, more compact, and saves space, increasing the usable space in the cockpit; the sliding rail structure ensures smooth transmission and makes the sliding display screen smoother.

[0015] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0021] The following detailed description illustrates the specific implementation method:

[0022] Example

[0023] A mechanism for enabling the display screen 9 to slide left and right, combined with Figures 1-4 As shown, it includes a mechanism frame, a drive unit, and a transmission unit.

[0024] The mechanism frame includes a front housing 8, a middle frame 3, and a rear cover 15. The front housing 8 is attached to the middle frame 3 by screws, and the rear cover 15 is attached to the middle frame 3 by screws. The entire mechanism frame is used to install the drive unit and the transmission unit.

[0025] A PCB13 is attached to the frame 3 of the mechanism by screws, and the PCB13 outputs signals to the drive unit.

[0026] The drive unit includes a motor 14, a motor bracket 2, a gearbox 1, and transmission components. The motor 14 is connected to the PCB 13 via a wiring harness; the motor 14 is connected to the motor bracket 2 via screws, and the motor bracket 2 is connected to the gearbox 1 via screws. The gearbox 1 is mounted on the mechanism's middle frame 3 via screws. The motor 14 is arranged along the length of the mechanism's middle frame 3, which has corresponding mounting slots. The transmission components include a worm gear 16 and a worm 17. The worm 17 is connected to the output end of the gearbox 1, and the worm gear 16 meshes with the worm 17, driving the transmission unit.

[0027] The transmission unit includes a synchronous belt 12, a synchronous pulley 4, a driven pulley 11, a guide rail 5, a slider 6, a fixing block 7, and a mounting bracket 10. A worm gear 16 is coaxially connected to the synchronous pulley 4. The driven pulley 11 is screwed to the mechanism's inner frame 3, and the synchronous belt 12 is wound around the synchronous pulley 4 and the driven pulley 11. The guide rail 5 is screwed to the mechanism's inner frame 3 and is positioned above the synchronous belt 12; two sliders 6 slide into the guide rail 5 from both ends; the fixing block 7 is screwed to simultaneously fix the synchronous belt 12 and the sliders 6, and the sliders 6 are screwed to the mounting bracket 10; the mounting bracket 10 is screwed to the display screen 9. The front housing 8 of the mechanism has a sliding groove for the mounting bracket 10 to extend outside the front housing 8, after which the mounting bracket 10 connects to the display screen 9.

[0028] In practice:

[0029] PCB13 outputs a signal to motor 14, which drives gearbox 1 to work. Gearbox 1 drives synchronous belt 12 to rotate. Synchronous pulley 4 drives synchronous belt 12, fixed block 7, and slider 6 to move. Since mounting bracket 10 is fixed on slider 6, display screen 9 moves with synchronous belt 12.

[0030] This embodiment features a long, narrow frame within which both the drive and transmission mechanisms are housed. This design results in a more compact structure and reduced space occupancy. The drive unit includes a horizontally mounted motor 14, which is driven by a worm gear 16 and a worm 17, reducing the overall structural thickness. The transmission unit utilizes a synchronous belt 12, which can be made thinner than the lead screw and nut mechanism, further reducing the overall structural thickness. The guide rail 5, slider 6, and fixing block 7 within the transmission unit are arranged vertically with the synchronous belt 12, further reducing the overall structural thickness and space occupancy. Simultaneously, the synchronous belt 12's transmission method allows for smoother movement of the display screen 9 with less noise. The above description is merely an embodiment of this utility model; well-known structural features and characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model and will not affect the effectiveness or practicality of the utility model.
