Description

Technical Field

[0001] This utility model relates to the technical field of automotive small table driving devices, and in particular to an automotive small table flipping driver. Background Technology

[0002] Traditional car seat tray tables are manually adjustable, flipped open, or folded away. With the vigorous development of new energy vehicles and the increasing abundance of various comfort and luxury features, the demand for intelligent vehicles is also rising. The need for flip-up tray tables is a major trend in comfort, and major car manufacturers and customers are beginning to pursue intelligent and electric flip-up functionality. Within a limited space, a high-torque flip actuator is needed to open and fold the tray table.

[0003] However, the existing flipping mechanism of the small table cannot output large torque within a limited space. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the flipping mechanism of the small table cannot output large torque in a limited space. Therefore, this utility model provides a flipping driver for a car small table that can output large torque in a limited space.

[0005] The technical problem to be solved by this utility model can be achieved through the following technical solution: A car tray table flipping actuator includes: a bottom housing and a top cover; and further includes: A motor is installed inside the bottom housing, and a first-stage worm gear is mounted on the output shaft of the motor; A series of double gears are installed in the bottom shell. The input end of the first-stage double gear meshes with the first-stage small worm. The series of double gears mesh in sequence, and the small worm of the last stage double gear forms the output. An output shaft is installed inside the bottom housing. The small worm gear of the last stage double gear meshes with the second stage interlaced helical gear on the output shaft to drive the output shaft to rotate. The output shaft drives the car's small table to flip.

[0006] In a preferred embodiment of this utility model, the several stages of double gears are divided into four stages of double gears, wherein: the large helical gear on the first stage double gear forms the input end of the first stage double gear and meshes with the first stage small worm; the second stage small worm on the first stage double gear meshes with the large helical gear on the second stage double gear; the small gear of the second stage double gear meshes with the large gear of the third stage double gear; the small gear of the third stage double gear meshes with the large gear of the fourth stage double gear; and the first stage staggered helical gear of the fourth stage double gear meshes with the second stage staggered helical gear on the output shaft.

[0007] In a preferred embodiment of this utility model, the output shaft and the second-stage interlaced helical gear are manufactured as a single unit.

[0008] In a preferred embodiment of this invention, the axis of the motor is parallel to the axis of the output shaft.

[0009] In a preferred embodiment of the present invention, the output shaft is supported on the bottom shell by a pair of sliding bearings or bushings.

[0010] By adopting the above technical solution, the entire driver is flattened, while meeting the requirements of high torque and low speed scenarios. The staggered helical gear design changes the output direction from a vertical motor to a horizontal output. While improving transmission efficiency, sliding bearings (bushings) are added to both ends of the cylindrical helical gear nut to avoid direct friction between the cylindrical surface of the gear and the housing, thus preventing wear and failure after long-term use.

The motor 300 is a flat motor, which is installed in the motor mounting cavity 110 of the bottom shell 100. The first-stage small worm gear 310 is installed on the output shaft of the motor 300.

[0015] The first-stage double gear 400, the second-stage double gear 500, the third-stage double gear 600, and the fourth-stage double gear 700 are installed inside the base housing 100. The large helical gear 410 of the first-stage double gear 400 forms the input end of the first-stage double gear 400 and meshes with the first-stage small worm 310. The second-stage small worm 420 on the first-stage double gear meshes with the large helical gear 510 on the second-stage double gear 500. The small gear 520 of the second-stage double gear 500 meshes with the large gear 610 of the third-stage double gear 600. The small gear 620 of the third-stage double gear 600 meshes with the large gear 710 of the fourth-stage double gear 700.
