Description

Technical Field

[0001] This utility model relates to the field of vehicle display technology, and in particular to a hinged vehicle display flip drive module. Background Technology

[0002] In-vehicle displays are electronic devices installed inside automobiles to provide various information displays and entertainment functions. With the improvement of living standards, in-vehicle displays have been increasingly widely used in some family cars or commercial vehicles to enhance the enjoyment of passengers during their journeys.

[0003] Some modern in-vehicle displays are installed on the ceiling of cars, with the screen flipping relative to its base, which is fixed to the car's ceiling. When needed, the screen flips down to open for passenger viewing; when not in use, it flips up to fold away, saving interior space. The screen's flipping is achieved by a mechanism mounted within the base. The core of this mechanism typically includes a motor and a gearbox. The screen is directly connected to the gearbox's output shaft, and the motor drives the shaft, causing the screen to flip.

[0004] However, the existing flip drive mechanism is only connected to the display screen through the output shaft. The support effect on the display screen during the flipping process is poor, and it cannot stably drive the display screen to flip. The display screen is prone to shaking during the flipping process and when stationary, which affects the user experience. Summary of the Invention

[0025] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0026] like Figures 1 to 6 As shown, a hinged-arm vehicle display flip-up drive module includes a base 1 and a hinged arm 4. One end of the hinged arm 4 is rotatably connected to the base 1. A guide rail 8 and a drive device 3 are provided on the base 1. A slider 9 is slidably connected on the guide rail 8. A transmission mechanism is provided between the drive device 3 and the slider 9. The drive device 3 drives the slider 9 to move along the guide rail 8 through the transmission mechanism. A movable shaft 5 is connected to the slider 9.

[0027] This invention is used to drive the display screen 13 to rotate. As shown in Figure 6, during installation, the movable shaft 5 is connected to the display screen 13, and one end of the crank arm 4 is hinged to the back of the display screen 13. At this time, the display screen 13, the crank arm 4, the slider 9, the guide rail 8, and the base 1 constitute a slider 9 linkage mechanism. The slider 9 is driven to move by the driving device 3, thereby realizing the rotation of the display screen 13. In this invention, the display screen 13 is connected to both the movable shaft 5 and the crank arm 4. Under any circumstances, the display screen 13 receives simultaneous support from both the movable shaft 5 and the crank arm 4. Compared with the traditional single-axis connection method, this invention greatly improves the support of the display screen 13 and greatly enhances its stability, making the display screen 13 less prone to shaking whether it is stationary or during rotation, thereby improving its user experience.

[0028] This utility model adopts a modular design concept. The articulated arm type vehicle display flip drive module is an independent module that can be installed or removed independently. When the module malfunctions, it can be disassembled separately for inspection or replacement, facilitating maintenance. The base 1 has several screw holes, allowing for easy connection between the base 1 and the base of the vehicle display.

[0029] A rocker arm 12 is connected to the slider 9. One end of the rocker arm 12 is rotatably connected to the slider 9, and the other end of the rocker arm 12 is rotatably connected to one end of the movable shaft 5.

[0030] Specifically, the transmission mechanism includes a lead screw 7, one end of which is connected to the drive device 3. The lead screw 7 and the slider 9 are threaded together. The drive device 3 drives the lead screw 7 to rotate. The lead screw 7 is parallel to the guide rail 8. The rotation of the lead screw 7 by the drive device 3 causes the slider 9 to move. The slider 9 is provided with a threaded hole 9a, through which the lead screw 7 passes.

[0031] A cover plate 2 is connected to the base 1. The cover plate 2 is connected to the base 1 by screws.

[0032] The base 1 is provided with a drive device mounting area 1a and a guide rail mounting area 1b. The drive device mounting area 1a is located at one end of the guide rail mounting area 1b. The drive device 3 is installed in the drive device mounting area 1a, and the guide rail 8 is installed in the guide rail mounting area 1b. Both the guide rail 8 and the drive device 3 are connected to the base 1 by screws.

[0033] An extension 1c is provided on one side of the base 1, and a bushing 1d is provided on the extension 1c. A trunnion is provided at one end of the crank arm 4, and the trunnion and the bushing 1d are rotatably engaged.

[0034] A limit switch 11 is provided on the base 1, and the limit switch 11 is located at one end of the guide rail 8. When the slider 9 moves to one end of the guide rail 8, the slider 9 contacts the limit switch 11 and triggers the limit switch 11, thereby stopping the drive device 3.

[0035] The base 1 has a through groove for the movable shaft 5 to pass through. A baffle plate 10 is provided on one side of the through groove. The baffle plate 10 is made of flexible material and has a slit. The movable shaft 5 passes through the slit in the baffle plate 10. The baffle plate 10 serves two purposes: firstly, it conceals the internal structure, thus hiding its unsightly appearance; secondly, it also provides some dust protection.

[0036] In this embodiment, the shielding sheet 10 is made of rubber.

[0037] The crank arm 4 includes a crank arm body 4a and a side cover plate 2 4b. The inside of the crank arm 4 is a hollow structure, and the wire 14 passes through the crank arm 4.

[0038] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
