Description

Technical Field

[0001] This utility model relates to the field of motor technology, and more specifically to a horizontal movement motor for an automobile seat. Background Technology

[0002] In a car, the seat is a crucial component that consumers value highly, requiring a comfortable design. Therefore, electric car seats have emerged. Electric car seats can electrically adjust the fore-and-aft position of the seat and the tilt angle of the backrest. Current electric seat leveling adjustments require a horizontal movement motor. When the driver operates the seat leveling button, an electrical signal is transmitted to the motor control module. The control module then drives the motor to rotate forward or backward according to the signal command. The motor's rotation is converted into horizontal movement of the seat through a transmission device, such as a worm gear mechanism or a rack and pinion mechanism, thereby achieving the adjustment of the seat's fore-and-aft position.

[0003] For example, there is a car seat horizontal movement motor with the prior art publication number CN214240511U. This utility model can be easily installed at the bottom of the car seat, has a good moisture-proof effect, can resist certain collisions without causing damage, and can ensure stable operation without shaking.

[0004] However, the existing technology described above still has the following problems in use: when the motor drives the car seat to move, the vibration during vehicle operation will cause the motor output shaft to rotate, which will reduce the stability of the car seat and affect driving safety. Based on this, the present invention provides a car seat horizontal movement motor. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a car seat horizontal movement motor. The motor body is protected by a fixed shell, and multiple first arc-shaped wear-resistant blocks on the fixed shell are tightly fitted to the outer walls of two second arc-shaped wear-resistant blocks, forming a ring-shaped clamping around the drive shaft, thereby ensuring that the drive shaft remains stable and effectively improving the positional stability of the car seat after adjustment. In addition, the first and second arc-shaped wear-resistant blocks are detachable, facilitating later maintenance and replacement, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a horizontal moving motor for an automobile seat, comprising a motor body and a fixed shell sleeved on the outer wall of the motor body. A drive shaft is connected to the motor body. A braking assembly is provided at the front end of the fixed shell. The braking assembly includes a circular plate. The front end of the circular plate has a through hole and multiple rectangular through holes, and the multiple rectangular through holes are arranged in a circular array with the through hole as the center. The front end of the drive shaft passes through the through hole and extends out of the outer side of the circular plate. A first arc-shaped wear-resistant block is provided inside each rectangular through hole. Two second arc-shaped wear-resistant blocks are embedded in the outer wall of the drive shaft. The second arc-shaped wear-resistant blocks are in contact with the first arc-shaped wear-resistant blocks. A drive assembly for driving the first arc-shaped wear-resistant blocks to move is provided inside each rectangular through hole.

[0007] In a preferred embodiment, the outer wall of the drive shaft is provided with an annular groove, and both second arc-shaped wear-resistant blocks can be detachably installed inside the annular groove.

[0008] In a preferred embodiment, the drive assembly includes an electric push rod fixed inside a rectangular through hole. A connecting block is fixed on the piston rod of the electric push rod. A connecting groove adapted to the connecting block is opened on the outer wall surface of each first arc-shaped wear-resistant block. The connecting block is fixed inside the connecting groove. The position of the first arc-shaped wear-resistant block is automatically adjusted by the electric push rod, making the adjustment faster.

[0009] In a preferred embodiment, a heat dissipation hole is provided at the rear end of the fixed shell to facilitate heat dissipation of the motor body. A filter screen is fixed inside the heat dissipation hole to block dust and impurities in the vehicle interior environment, so as to prevent dust and impurities from clogging the heat dissipation hole and affecting heat dissipation.

[0010] In a preferred embodiment, each first arc-shaped wear-resistant block is fixedly provided with sliders on both sides, and each rectangular through hole has a groove on the inner wall surface on both sides that matches the slider. The slider is located inside the groove. When the first arc-shaped wear-resistant block moves in the rectangular through hole, the sliders on both sides of the first arc-shaped wear-resistant block slide in the two grooves respectively, thereby improving the stability of the first arc-shaped wear-resistant block when it moves.

[0011] In a preferred embodiment, the outer wall of the fixed shell is fitted with two mounting plates distributed front and rear, and each mounting plate has multiple mounting holes arranged in a ring array, which can improve the connection between the fixed shell and the car seat.

[0012] In a preferred embodiment, the front end of the circular plate has a plurality of fixing holes arranged in a ring array, and each fixing hole is provided with a fastening bolt. The circular plate is fixed to the mounting plate by the fastening bolts to improve the connection between the circular plate and the mounting plate.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This utility model protects the motor body with a fixed shell, and at the same time, the multiple first arc-shaped wear-resistant blocks on the fixed shell and the outer walls of the two second arc-shaped wear-resistant blocks are closely attached to form a ring-shaped clamping of the drive shaft, thereby ensuring that the drive shaft is stable and does not move, effectively improving the positional stability of the car seat after adjustment. In addition, the first arc-shaped wear-resistant blocks and the second arc-shaped wear-resistant blocks adopt a detachable design, which facilitates later maintenance and replacement, and continuously maintains a reliable braking effect on the drive shaft.

[0026] Next, a through hole 402 and multiple rectangular through holes 403 are provided at the front end of the circular plate 401, and the multiple rectangular through holes 403 are arranged in a ring array with the through hole 402 as the center. The front end of the drive shaft 3 passes through the through hole 402 and extends out of the outer side of the circular plate 401. Each rectangular through hole 403 is provided with a first arc-shaped wear-resistant block 404. Two second arc-shaped wear-resistant blocks 405 are embedded in the outer wall of the drive shaft 3. Specifically, an annular groove 6 is provided in the outer wall of the drive shaft 3. The two second arc-shaped wear-resistant blocks 405 are detachably installed in the annular groove 6 by bolts. The second arc-shaped wear-resistant blocks 405 are in contact with the first arc-shaped wear-resistant blocks 404.

[0027] Each rectangular through hole 403 is equipped with a drive assembly 5 for moving the first arc-shaped wear-resistant block 404.
