Description

Technical Field

[0001] This utility model belongs to the field of motor technology and relates to an electric car seat motor with vibration reduction and noise reduction functions. Background Technology

[0002] The motor in an electric car seat is a core component, providing power to the seat and enabling electric adjustment of its horizontal distance, fore-aft height, and backrest angle. The application of electric car seat motors not only improves driving comfort and convenience for passengers but also adds a touch of technology and futuristic style to the car's interior design. When used in conjunction with the seat, the motor can easily drive the free adjustment of the seat angle; however, the following shortcomings exist during use:

[0003] First, the motor is installed inside the seat, and the operation of the motor will cause the motor itself to vibrate to a certain extent;

[0004] Secondly, during operation, due to changes in angle, there will be gaps between the motor and the seat mounting holes during assembly. In addition, the materials used to fix the seat and the mounting holes are slender, thin-walled metal structural components. When the motor is running, its own vibration will be transmitted to the metal structural components of the seat through the connecting screws and mounting brackets, causing resonance. This will aggravate the vibration of the entire chair and increase the noise level, reducing user comfort. Long-term operation will also affect the service life of the motor and the seat. Utility Model Content

[0005] This utility model provides an automotive electric seat motor with vibration reduction and noise reduction functions. It aims to solve the problem that existing seat motors, due to assembly gaps and slender thin-walled metal structural components, cause vibration of the motor itself and resonance transmitted to the metal structural components during operation, resulting in increased vibration and noise levels in the entire seat, reducing user comfort, and affecting the service life of the motor and seat.

[0006] To achieve the above objectives, this utility model provides an automotive electric seat motor with vibration reduction and noise reduction functions, including a motor body. At least one semi-enclosed column is integrally connected to the motor body. Both ends of the semi-enclosed column are provided with recessed positions. The center of the semi-enclosed column is provided with a mounting hole that penetrates the recessed position. The mounting hole is provided with a noise transmission damping bushing assembly for isolating the motor body, and both ends of the noise transmission damping bushing assembly are filled with the corresponding recessed positions.

[0007] Preferably, the noise conduction damping bushing assembly includes a soft rubber bushing and a hard bushing. The soft rubber bushing is provided in the mounting hole. Both ends of the soft rubber bushing are integrally connected with soft rubber gaskets. The soft rubber gaskets are used to fit on the recessed position. The soft rubber bushing has a through hole in the center. The hard bushing is fitted in the through hole. The soft rubber bushing and the hard bushing form an interference fit through the through hole.

[0008] Preferably, the rigid shaft sleeve passes through a screw with a nut, the screw being used to securely lock the motor body.

[0009] The advantages of this utility model over the prior art are:

[0010] This utility model provides an automotive electric seat motor with vibration reduction and noise reduction functions. It uses a soft rubber shaft sleeve to buffer and isolate the vibration of the motor body, and uses a hard shaft sleeve to fix the motor body to form a rigid support effect, thereby achieving the effects of isolating vibration, reducing noise, and extending service life.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] To achieve the above objectives, this utility model provides an automotive electric seat motor with vibration reduction and noise reduction functions, see reference. Figure 1-3 As shown, the device includes a motor body 1, on which at least one semi-enclosed column 2 is integrally connected. Both ends of the semi-enclosed column 2 are provided with recessed positions 3. The center of the semi-enclosed column 2 is provided with a mounting hole 4 that penetrates the recessed position 3. The mounting hole 4 is provided with a noise conduction damping bushing assembly 5 for isolating the motor body 1, and both ends of the noise conduction damping bushing assembly 5 are filled with the corresponding recessed positions 3.

[0020] The noise conduction damping bushing assembly 5 includes a soft rubber bushing 6 and a hard bushing 7. The soft rubber bushing 6 is provided in the mounting hole 4. Both ends of the soft rubber bushing 6 are integrally connected with soft rubber gaskets 8. The soft rubber gaskets 8 are used to fit on the recessed platform 3. The soft rubber bushing 6 has a through hole 9 in the center. The hard bushing 7 is fitted in the through hole 9. The soft rubber bushing 6 and the hard bushing 7 form an interference fit through the through hole 9. The hard bushing 7 is penetrated by a screw 10 with a nut. The screw 10 is used to securely lock the motor body 1.

[0021] In this embodiment, to address the vibration and noise issues generated by existing automotive electric seats when adjusting the backrest tilt angle and seat fore-aft distance, the motor body 1 is installed inside the frame of the automotive electric seat. Specifically, the mounting and fixing part of the motor body 1 is redesigned as a semi-enclosed column 2 with a notch on the side. A soft rubber sleeve 6 is installed through the notch, and the soft rubber gaskets 8 at both ends of the soft rubber sleeve 6 fill the recessed area 3. In this way, the soft rubber sleeve 6 can reduce vibration, isolate vibration, and reduce noise for the motor body 1. Then, a rigid sleeve 7 is inserted... The soft rubber sleeve 6 is placed inside the through hole 9 to provide support. At the same time, the screw 10 passes through the hard sleeve 7 for fastening and locking, which will press against and compact the soft rubber pads 8 at both ends. Moreover, the presence of the soft rubber pads 8 between the motor body 1 and the car electric seat isolates vibration transmission, thereby reducing the noise of the car electric seat during the drive adjustment process and extending its service life. The soft rubber sleeve 6 can be made of various stretchable materials such as soft rubber, soft silicone, and nitrile rubber, while the hard sleeve 7 can be made of various rigid support materials such as stainless steel and copper.

[0022] The use of this automotive electric seat motor helps to isolate vibration, reduce noise and vibration during operation, improve user experience and comfort, and reduce wear to some extent, thereby increasing the lifespan of both the motor body 1 and the automotive electric seat. It features a vibration transmission path that isolates the motor body 1 from the transmission of vibration between the motor body 1 and the automotive electric seat during operation, thus reducing noise and improving user comfort. Furthermore, the flexible connection between the motor body 1 and the frame prevents vibration from being transmitted along the metal structure, further reducing vibration during operation and extending service life.

[0023] In summary, this utility model provides an automotive electric seat motor with vibration reduction and noise reduction functions. The motor body 1 is buffered and isolated by the soft rubber sleeve 6, and the motor body 1 is fixedly installed by the rigid sleeve 7 to form a rigid support effect, thereby achieving the effects of isolating vibration, reducing noise, and extending service life.
