Description
Technical Field
The invention relates to the field of vehicle parts, in particular to a tail gate damper and a vehicle, and particularly relates to a tail gate damper capable of avoiding noise by reducing vibration of a tail gate and a vehicle.
Background
When the engine of the vehicle is in a start state, the vehicle body is affected by the rotational speed of the engine, and further, more or less vibrations are generated. Among them, the vibration of the tailgate of the vehicle approaches the vibration of the engine, which may cause a resonance phenomenon between the tailgate and the engine, and the resonance phenomenon further causes the generation of noise, causing discomfort to passengers in the vehicle.
To solve this problem, the vehicle is provided with a damper as shown in fig. 1 on an inner panel 10 of a tailgate of the vehicle, which is composed of a weight block 12 and rubber blocks 11 fixed to both ends of the weight block 12. However, the rubber blocks 11 are only connected to both sides of the weight block 12, and therefore, only the vibration of the tailgate can be transmitted from both sides of the weight block 12, so that the transmission direction of the vibration and the vibration damping direction of the weight block 12 are limited, and the degree of deformation of the rubber blocks 11 is limited because of their block shape. Therefore, the conventional shock absorber has a limited effect of reducing vibration of the tailgate of the vehicle to prevent a resonance phenomenon and noise.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In one aspect, as shown in FIG. 2, the present invention provides a vehicle rear door absorber. According to the embodiment of the present invention, the tailgate absorber is disposed on the inner panel 10 of the vehicle tailgate, and preferably, the tailgate absorber should be disposed at or near the center of gravity of the vehicle tailgate inner panel 10 to better receive vibration generated at the vehicle tailgate.
A tailgate absorber according to an embodiment of the present invention may include: a damper housing 20 provided on the vehicle tailgate inner panel 10; a first magnet 21 attached and fixed to an inner side surface of the damper housing 20; a second magnet 22 suspended within the damper housing 20; and a plurality of cables 23 connecting the first magnet 21 and the second magnet 22.
Specifically, the damper housing 20 may be fixed to the tailgate inner panel 10 of the vehicle by means of bolting, an inner side surface thereof is provided with the first magnet 21, and the first magnet 21 is fit-fixed to an inner side surface of the damper housing 20.
When the damper housing 20 is provided to the tailgate inner panel 10, a space composed of the inner side surface of the damper housing 20 surrounding the outer side surface of the tailgate inner panel 10 is formed inside the damper housing 20, and the second magnet 22 is suspended in the space.
Specifically, the second magnet 22 and the first magnet 21 are connected by a plurality of cables 23, and the surfaces of the second magnet 22 and the first magnet 21 that face each other have the same magnetism (for example, in the present embodiment, the magnetism of the surfaces of the first magnet 21 and the second magnet that face each other is N-pole), so that an opposing force is generated between the first magnet 21 and the second magnet 22. Since the first magnet 21 is fixedly disposed on the damper housing 20 and the damper housing 20 is fixed on the tailgate inner panel 10, the first magnet 21 is not changed in position due to the repulsive force received, and the second magnet 22 is connected to the first magnet 21 by the plurality of cables 23 while receiving the repulsive force of the first magnet 21, and thus is suspended in the inner space of the damper housing 20 and the suspended position thereof is relatively stable.
Further, when the vehicle tailgate inner panel 10 vibrates, the vibration is transmitted to the tailgate absorber according to the embodiment of the present invention, and the tailgate absorber transmits the received vibration to the second magnet through the plurality of cables 23, and at this time, the second magnet 22 vibrates in the inner space of the absorber housing 20 according to the vibration of the vehicle tailgate to absorb and damp the vibration of the vehicle tailgate.
Further, since the second magnet 22 is suspended in the inner space of the damper housing 20 and the first magnet 21 is attached to the entire inner side surface of the damper housing 20, the entire surface of the second magnet 22 receives the repulsive force from the first magnet 21, and thus the oscillating motion according to the vibration of the vehicle tailgate can be performed in any direction, and the vibration received by the vehicle tailgate can be more effectively reduced.
Alternatively, the second magnet 22 has a hemispherical shape in order that each surface of the second magnet 22 may be uniformly subjected to the opposing force from the first magnet 21. In addition, in order to make it possible for the second magnet 22 to more flexibly perform the oscillating motion inside the damper housing 20 and to return to the position of the raw material after the vibration of the tailgate stops, it is optional to use a rubber material for each of the plurality of cables 23 connecting the first magnet 21 and the second magnet 22.
In addition, in the tailgate shock absorber according to the embodiment of the present invention, the degree of reducing tailgate vibration is related to the oscillating motion of the second magnet 22, and the oscillating motion of the second magnet 22 is related to the force received by the second magnet 22, so that the magnetic force, which is the repulsive force between the first magnet 21 and the second magnet 22, can be adjusted according to actual requirements, and also, the number, position, elastic strength, and the like of the plurality of cables 23 connecting the first magnet 21 and the second magnet 22 can be adjusted according to actual requirements to achieve a desired damping effect, which is not limited by the present invention.
In another aspect, the present invention also provides a vehicle including a tailgate absorber according to an embodiment of the present invention.
In summary, the present invention provides a tailgate shock absorber, comprising: a damper housing provided on a vehicle tailgate inner panel; the first magnet is attached and fixed on the inner side surface of the shock absorber shell; a second magnet suspended in a space formed by the damper housing surrounding the vehicle rear door inner panel; and a plurality of cables connecting the first magnet and the second magnet to fix a levitation position of the second magnet and transmit vibration to the second magnet. The vehicle tail gate shock absorber provided by the invention has a simple structure, and can effectively reduce the vibration of the vehicle tail gate, thereby preventing the resonance phenomenon between the tail gate and an engine, further avoiding the generation of noise, and providing good sensory experience for passengers.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may be modified or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
