Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction of vehicles, and specifically provides a steering column adjustment motor component and a vehicle comprising the component. Background Art

[0002] In the process of driving the transmission mechanism to achieve power transmission, noise is particularly obvious at the connection between components. Take the steering column adjustment motor in the vehicle as an example. The structures / components that are directly or indirectly connected to it include relatively fixed structures / components and structures / components that can generate movement. When the current steering column adjustment motor is used for connection, it is usually hard-connected with other components, which will cause certain connection-related noise.

[0003] With the development of vehicle technology and users' increasingly higher requirements for vehicle performance / experience in all aspects, noise level is a more important aspect of vehicle performance. For the steering column motor, since it is located close to the cabin space of the driver's cabin, it is particularly necessary to effectively deal with the noise associated with it. However, the current steering column motor using brushed DC motor has reached a bottleneck, that is, the noise level of the motor itself is difficult to meet the new requirements. Therefore, it is quite necessary to achieve noise reduction at the connection between the components related to the steering column motor.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Utility Model Content

[0005] The utility model aims to at least partially solve the above technical problems, and specifically, to provide a steering column adjustment motor assembly which can at least to some extent improve the noise problem associated with the steering column adjustment motor.

[0007] With such a configuration, it is possible to effectively reduce noise caused by the connection relationship with the steering column adjustment motor.

[0008] It is understandable that those skilled in the art can determine the structure, number, etc. of the noise reduction unit according to actual needs. For example, one or more noise reduction units can be configured at one connection. When the noise reduction unit includes multiple units, the structure and corresponding noise reduction principles of the multiple noise reduction units can be the same or different. Also, the number, type, and specific configuration orientation of the noise reduction units corresponding to different connections can be the same or different.

[0009] And, it can be understood that those skilled in the art can determine the specific transmission form of the first transmission mechanism according to actual needs, as long as it is ensured that it and the reduction gearbox assembly and its associated components can reliably transmit the driving torque of the steering column adjustment motor to the movable body.

[0010] In addition, it should be noted that the specific structural form of the fixed body and the movable body and the specific functions they implement can be determined in combination with the actual scenario and are not particularly limited here.

[0020] It is understandable that those skilled in the art can determine the structural form of the first part and the second part and the specific way of combining the two into the first noise reduction part according to actual needs.

[0062] In addition, in order to better illustrate the present invention, many specific details are given in the following specific embodiments. Those skilled in the art should understand that the present invention can also be implemented without certain specific details. In some examples, the principle of the steering column adjustment motor in its application scenario, which is well known to those skilled in the art, is not described in detail in order to highlight the main purpose of the present invention.

[0063] Main reference Figures 1 to 4 In a possible implementation, a vehicle includes a vehicle body, a steering column adjustment motor assembly 100 disposed on the vehicle body, a fixed body (structure or structural assembly) 200 fixed relatively to the vehicle body, and a moving body (structure or structural assembly) 300 capable of generating movement under the driving of the steering column adjustment motor assembly. The steering column adjustment motor assembly 100 includes a steering column adjustment motor 1, a reduction gearbox assembly 2, and a first transmission mechanism 3. The power output shaft of the steering column adjustment motor 1 is connected to the power input side of the reduction gearbox assembly, the power output side of the reduction gearbox is connected to the power input side of the first transmission mechanism, the power output side of the first transmission mechanism 3 is fixed to the moving body 300, the housing of the steering column adjustment motor 1 is fixed to the reduction gearbox assembly, and the reduction gearbox assembly 2 is fixed to the fixed body 200. In this way, a power transmission path of the steering column adjustment motor-reduction gearbox assembly-first transmission mechanism-moving body can be formed.

[0064] In a possible embodiment, the reduction gearbox assembly 2 includes a reduction gearbox housing and a second transmission mechanism disposed in the reduction gearbox housing, such as the second transmission mechanism may include but is not limited to a combination of one or more of a spur gear pair, a bevel gear pair, a worm gear mechanism, etc. The housing of the steering column adjustment motor 1 is fixedly disposed in the reduction gearbox housing, and the power output shaft of the steering column adjustment motor 1 is connected to the power input side of the second transmission mechanism. In this example, the first transmission mechanism 3 is a screw-nut mechanism. The power input side of the second transmission mechanism is connected to the screw 31 of the screw-nut mechanism, and the nut 32 of the screw-nut mechanism is fixedly connected to the moving body 300. In this way, a power transmission path of the steering column adjustment motor-reduction gearbox assembly-screw-nut mechanism-moving body can be formed. That is, when the steering column adjusting motor is in a working state, the steering column adjusting motor (single steering column adjusting motor) is decelerated through the second transmission mechanism (such as a worm gear mechanism) in the reduction gear housing after being energized, and then drives the screw of the screw nut mechanism to rotate, and the nut of the screw nut mechanism moves along the screw, thereby driving the movement to realize its movement along the screw.

[0065] It can be seen that in the above-mentioned connection, in the fixed connection relationship, there are at least the following three connections: the first connection is the connection between the housing of the steering column adjustment motor and the housing of the reduction box, the second connection is the connection between the housing of the reduction box and the fixed body, and the third connection is the connection between the nut and the moving body. In the process of realizing the corresponding power transmission based on the aforementioned power transmission path, if the above-mentioned connection adopts a hard connection, it will bring obvious noise due to the high-speed operation of the related driving transmission components on the power transmission path. Therefore, the utility model adds noise reduction parts at multiple connections to enable the vehicle including the steering column adjustment motor assembly to obtain a good noise level. In this example, the noise reduction part includes two added first noise reduction parts and second noise reduction parts for the three aforementioned connections.

[0066] In a possible implementation, a mounting hole 21 is provided on the reduction box housing, and the reduction box housing and the fixed body can be fixedly connected by means of the cooperation between the mounting hole and a fastener such as a bolt. A first noise reduction part is arranged at the connection.

[0067] In a possible embodiment, the first noise reduction part includes a pair of T-shaped rubber sleeves arranged in an opposing manner in the mounting hole, such as being respectively recorded as a first T-shaped rubber sleeve 41 (located at the top) and a second T-shaped rubber sleeve 42 (located at the bottom). In the assembled state, the axial portions of the two T-shaped rubber sleeves are sleeved on the outside of the fastening bolt 201, that is, arranged between the outer wall of the fastening bolt 201 and the inner wall of the first mounting hole, and the end surface portions of the two T-shaped rubber sleeves are sandwiched between the surfaces of the fixed body and the two ends of the reduction gear housing corresponding to the first mounting hole. For example, if the fixed body has a first surface and a second surface at the positions corresponding to the upper end and the lower end of the first mounting hole, respectively, the end surface portion of the first T-shaped rubber sleeve located at the top is sandwiched between the lower part of the first surface and the outer surface of the reduction gear housing corresponding to the upper end of the first mounting hole, and the end surface portion of the second T-shaped rubber sleeve located at the bottom is sandwiched between the upper part of the second surface and the outer surface of the reduction gear housing corresponding to the lower end of the first mounting hole. In this way, by setting a pair of T-shaped rubber sleeves, the noise generated by the hard connection at this connection can be effectively reduced. Specifically, it is expected to reduce the axial and radial vibrations of the single steering column adjusting motor along the mounting hole and the spatial swing caused by the combined force, thereby effectively weakening the transmission of the vibration of the steering column adjusting motor to the fixed body and thereby reducing the noise caused thereby.

[0068] In a possible implementation, the nut 32 of the screw nut mechanism is a plastic nut, and the moving body can be fixedly connected to the nut by multi-point connection, so as to realize the movement of the moving body along the axial direction of the screw. A second noise reduction part is arranged at the connection.

[0069] In a possible implementation, the nut 32 includes a nut body 321, and nut mounting columns 322 are respectively disposed at the upper end and the lower end of the nut body 321. The second noise reduction portion is disposed at a position of the plastic nut corresponding to the nut mounting column 322.

[0070] In a possible embodiment, the second noise reduction part includes a rubber bushing, and the rubber bushing 5 includes a tubular part 51 sleeved on the outside of the nut mounting column 322 and a pad-shaped part 22 laid on the outer surface of the nut body 321 near the nut mounting column 322. The moving body 300 has two second mounting holes 301 corresponding to the two nut mounting columns 322, and the tubular part of the nut mounting column 322 can extend into the corresponding second mounting holes 301. In this way, in the assembled state, the tubular part 51 is arranged between the outer surface of the nut mounting column 322 and the inner surface of the corresponding second mounting hole 301, and the pad-shaped part 52 is sandwiched between the surface of the moving body 300 corresponding to the position of the second mounting hole 301 and the end face of the nut body 321. Exemplarily, for the nut mounting column 322 arranged at the upper end of the nut body 321, its pad-shaped part 52 is sandwiched between the lower surface of the moving body 300 and the upper end face of the nut body 321 in the assembled state. In this way, the noise generated by the hard connection at this connection can be effectively reduced by providing a pair of rubber bushings 5. Specifically, it is expected that the vibration of the single steering column adjustment motor can be absorbed in the axial and radial directions by the rubber bushings and thus the vibration of the single steering column adjustment motor can be effectively isolated from being transmitted to the moving body, thereby reducing the noise caused thereby.

[0071] It can be seen that in the preferred embodiment of the utility model, by configuring a pair of T-shaped rubber structures as the first noise reduction part at the first mounting hole where the steering column adjustment motor assembly is fixed to the fixing member, the axial and radial vibrations of the steering column adjustment motor and the spatial swing caused by the synthetic force can be effectively reduced, and thus the vibration of the steering column adjustment motor is isolated from being transmitted to the fixed body. By using a rubber bushing at the nut where the steering column adjustment motor assembly is fixed to the movable part, the vibration of the steering column adjustment motor can be effectively absorbed in the axial and radial directions of the nut mounting column, and thus the vibration of the steering column adjustment motor is isolated from being transmitted to the moving body. In this way, by adding a noise reduction unit at two connections indirectly related to the steering column adjustment motor, the influence of the vibration generated by the steering column adjustment motor during power transmission on the noise is effectively attenuated, and the noise level of the vehicle is significantly improved.

[0072] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
