Description

Technical Field

[0001] This utility model belongs to the field of drive mechanism technology, specifically relating to a drive mechanism for automotive seat slide rails. Background Technology

[0002] In automotive seating systems, the drive mechanism of the seat rails plays a crucial role in enabling flexible seat adjustments, directly impacting the comfort and convenience of passengers.

[0003] Traditional drive mechanisms typically place the motor on the side of the slide rail, with the motor output shaft directly delivering power. When the car seat moves backward, the motor's position limits the maximum distance the seat can move backward, severely impacting the seat's adjustment range. This prevents occupants from adjusting the seat to their most comfortable position, especially taller individuals who lack sufficient legroom. This limits further improvements in comfort and functionality, reducing the driving experience and the car seat's market competitiveness.

[0004] Therefore, in order to solve the above problems, it is necessary to design a drive mechanism for automotive seat slide rails. Utility Model Content

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0043] like Figures 1 to 3 As shown, this embodiment provides a drive mechanism for an automotive seat slide rail, including:

[0044] A base plate 1 has one end bent downwards to form a first bend 101; a first bevel gear 2 is connected to a bearing on the base plate 1; a second bevel gear 3 is connected to a bearing on the first bend 101 and meshes with the first bevel gear 2; a transmission rod 4 has one end connected to the second bevel gear 3 and the other end adapted to connect to a slide rail; a motor 5 is mounted on the base plate 1, and its output shaft is connected to the first bevel gear 2; wherein the motor 5 is adapted to drive the second bevel gear 3 to rotate through the first bevel gear 2, and the second bevel gear 3 drives the transmission rod 4 to rotate, thereby driving the slide rail to rotate; wherein a 90° bend in the first bend 101 is preferred; wherein by setting the first bevel gear 2 and the second bevel gear 3, the transmission direction is changed; wherein by setting the transmission rod 4, the rotational motion of the second bevel gear 3 is converted into the power to drive the slide rail to move.

[0045] In this embodiment, by setting a first bevel gear 2 on the base plate 1 and a second bevel gear 3 on the first bend 101, and by meshing the first bevel gear 2 and the second bevel gear 3, the transmission direction is turned 90°, thereby changing the installation position of the motor 5, not occupying the space on the side of the slide rail, significantly increasing the maximum distance the seat can move backward, providing more legroom for drivers and passengers (especially tall people), and improving driving comfort and seat functionality.

[0046] A gearbox 6 is provided between the base plate 1 and the motor 5; wherein the gearbox 6 is mounted on the base plate 1 and its output end is connected to the first bevel gear 2; and the motor 5 is mounted on the gearbox 6 and its output end is connected to the input end of the gearbox 6; the motor 5 is adapted to drive the first bevel gear 2 to rotate through the gearbox 6; wherein by setting the gearbox 6, speed reduction and torque increase are achieved, reducing the output speed of the motor 5 while increasing the torque, avoiding the impact of seat adjustment caused by the high speed direct drive of the motor 5, and making the seat movement process smoother and gentler.

[0047] The gearbox 6 includes: an open housing 601 mounted on a base plate 1, a cover 602 covering the open housing 601, and at least three transmission gears 603 disposed within the open housing 601; wherein each transmission gear 603 is bearing-connected to the open housing 601 and the cover 602; and adjacent transmission gears 603 mesh with each other; the motor 5 is mounted on the cover 602, and its output end is connected to the first transmission gear 603; the first bevel gear 2 is connected to the last transmission gear 603; the motor 5 is adapted to drive the first transmission gear 603 during startup. When wheel 603 rotates, the first transmission gear 603 drives the end transmission gear 603 to rotate via the intermediate transmission gear 603, and the end transmission gear 603 drives the first bevel gear 2 to rotate. By setting an open box 601 and a box cover 602, a closed space is formed to protect the internal transmission gear 603 from dust, oil and other contaminants, while also enhancing the overall structural strength of the gearbox 6. By setting at least three transmission gears 603, the position of motor 5 is changed again, allowing motor 5 to avoid the internal structure of the seat, thus increasing the distance the seat moves backward a second time.

[0048] The top of the cover 602 is provided with a top plate 7; wherein the motor 5 is mounted on the top plate 7; and the output shaft of the motor 5 passes through the bottom plate 1 and is connected to the first end transmission gear 603; wherein by setting the top plate 7, a stable mounting platform is provided for the motor 5.

[0049] The lower ends of the first bending portion 101 are bent inward on both sides to form a second bending portion 102; wherein a U-shaped connector 8 is connected to the second bending portion 102; wherein the U-shaped connector 8 is adapted to be fixed on the slide rail.
