The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
In the description of the present invention, it is to be understood that the terms "length," "width," "upper," "lower," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present invention and simplicity in description, but do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular manner, and thus are not to be construed as limiting the present invention.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
A shock absorber 10 for a vehicle according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 4.
Referring to fig. 1 to 3, a shock absorber 10 for a vehicle according to an embodiment of the present invention may include: the shock absorber comprises a cylinder body 1 and a rod system component 3, wherein a cavity is arranged in the cylinder body 1, a medium is contained in the cavity, the rod system component 3 is at least partially arranged in the cavity, and the rod system component 3 is suitable for reciprocating in the cavity, so that the shock absorber 10 can provide damping force to achieve shock absorption.
As shown in fig. 2 to 3, the linkage assembly 3 divides the cavity into a working chamber 21 and a pressure relief chamber 22, the linkage assembly 3 is provided with a pressure relief channel 4, and the pressure relief channel 4 is formed as follows: when the pressure in the working cavity 21 is not less than the preset pressure threshold, the pressure relief channel 4 is opened, the working cavity 21 is communicated with the pressure relief cavity 22 through the pressure relief channel 4, and when the pressure in the working cavity 21 is less than the preset pressure threshold, the pressure relief channel 4 is closed.
That is to say, when the pressure in the working chamber 21 reaches a certain pressure value, the pressure relief channel 4 is opened, at this moment, the working chamber 21 is communicated with the pressure relief chamber 22 through the hydraulic channel 4, at this moment, the medium located in the working chamber 21 flows to the pressure relief chamber 22 through the hydraulic channel 4, so that the rod system component 3 of the shock absorber 10 can move towards the working chamber 21 quickly, the damping force of the shock absorber 10 is reduced, and a better shock absorption effect can be provided.
It should be noted that normally open type flow holes for communicating the working chamber 21 and the pressure relief chamber 22 are provided on the components of the rod system assembly 3 (i.e. the connecting rod valve system 5 mentioned below), but because the diameter of the flow hole is constant, when the shock absorber 10 moves at a high frequency, for example, when a vehicle passes through a bumpy road, because the speed of the medium in the working chamber 21 flowing from the flow hole to the pressure relief chamber 22 is limited, the pressure in the working chamber 21 will be high in a short time, so that the moving stroke of the rod system assembly 3 is limited, the damping force of the shock absorber 10 is large, the damping effect of the shock absorber 10 is poor, the vehicle bump is large, and the riding comfort of the vehicle is affected.
Therefore, through the arrangement of the pressure relief channel 4, when the shock absorber 10 moves at a high frequency, after the pressure in the working cavity 21 reaches a preset pressure threshold value, the pressure relief channel 4 is opened, so that the speed of the medium flowing from the working cavity 21 to the pressure relief cavity 22 can be increased, the damping force of the shock absorber 10 can be effectively reduced, and the shock absorption effect of the shock absorber 10 is ensured to be good.
According to the shock absorber 10 for the vehicle, due to the arrangement of the pressure relief channel 4, when the shock absorber 10 moves at a high frequency, after the pressure in the working cavity 21 reaches a preset pressure threshold value, the pressure relief channel 4 is opened, and the working cavity 21 is communicated with the pressure relief cavity 22 through the pressure relief channel 4, so that the speed of a medium flowing from the working cavity 21 to the pressure relief cavity 22 can be increased, the damping force of the shock absorber 10 can be effectively and quickly reduced, and the comfort of the vehicle is ensured to be good.
Further, as shown in fig. 2-3, the bar system assembly 3 may include: the connecting rod 31 and the connecting rod pressure valve 34, wherein the connecting rod pressure valve 34 is positioned in the working cavity 21;
a first communicating hole 32 is formed in one end, located in the working cavity 21, of the connecting rod 31, a second communicating hole 33 is formed in the side wall, located in the pressure relief cavity 22, of the connecting rod 31, the first communicating hole 32 is communicated with the second communicating hole 33, and a pressure relief switch 35 is arranged on the connecting rod pressure valve 34;
the pressure relief switch 35 is formed as: when the pressure of the connection between the connecting rod pressure valve 34 in the working chamber 21 and one end of the connecting rod 31 is not less than the preset pressure threshold, the pressure relief switch 35 is opened, the working chamber 21 is communicated with the first communication hole 32, and when the pressure in the working chamber 21 is less than the preset pressure threshold, the pressure relief switch 35 is closed.
That is to say, the first communicating hole 32 and the second communicating hole 33 on the link 31 and the pressure relief switch 35 located in the link pressure valve 34 form the pressure relief channel 4, wherein the first communicating hole 32 is communicated with the second communicating hole 33, the pressure relief switch 35 is controlled by the pressure in the working chamber 21, when the pressure in the working chamber 21 reaches a preset pressure threshold, the pressure relief switch 35 is opened, and the pressure relief switch 35 is adapted to be communicated with the first communicating hole 32, the first communicating hole 32 is located in the working chamber 21, the second communicating hole 33 is located in the pressure relief chamber 22, and the pressure relief switch 35 is located in the working chamber 21, so when the pressure relief switch 35 is opened, the medium located in the working chamber 21 passes through the pressure relief switch 35 and then passes through the first communicating hole 32, and then flows from the second communicating hole 33 to the pressure relief chamber 22, thereby effectively reducing the damping value of the shock absorber 10.
It should be noted that the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
Further, the pressure relief switch 35 may be a permeable membrane, when the pressure in the working chamber 21 is not less than the preset pressure threshold, the permeability of the permeable membrane is greater than zero, and when the pressure in the working chamber 21 is less than the preset pressure threshold, the permeability of the permeable membrane is equal to zero, so as to ensure that when the pressure in the working chamber 21 reaches the preset pressure threshold, the medium in the working chamber 21 can flow into the first communication hole 32 through the pressure relief switch 35 and flow into the pressure relief chamber 22 from the second communication hole 33.
Further, the permeability of the permeable membrane is in positive correlation with the pressure in the working chamber 21, that is, the greater the pressure in the working chamber 21 is, the higher the permeability of the permeable membrane is, so that it is ensured that the shock absorber 10 has a moderate damping value when moving at a high frequency, and the better comfort of the vehicle is ensured.
In a particular embodiment, the permeability of the permeable membrane may be directly proportional to the pressure in the working chamber 21, thereby ensuring a relatively linear damping effect of the damper 10 and ensuring good comfort of the vehicle.
Specifically, as shown in fig. 3, the first communicating hole 32 is located at the bottom of one end of the connecting rod 31, and the pressure relief switch 35 is disposed opposite to the first communicating hole 32, so that the pressure relief switch 35 is ensured to be smoothly communicated with the first communicating hole 32.

Further, as shown in fig. 1 to 3, the cylinder block 1 may include: the working cylinder 11 and the bottom valve 12, the working cylinder 11 forms a hollow cavity with openings at two ends, and the bottom valve 12 is located at one end of the working cylinder 11 and is fixedly connected with the working cylinder 11.
In the specific embodiment, the other end of the cylinder 11 is connected to other components, such as: a vehicle body.
Specifically, the medium may be a liquid or a gas, and for example, the medium may be air or oil, or the like.
