Description

Technical Field

[0001] This invention relates to the field of vibration reduction technology, and in particular to a damping vibration reduction device and a vehicle. Background Technology

[0002] During vehicle operation, vibrations can degrade the user experience. Therefore, shock absorbers are necessary to absorb and filter vibrations generated during driving, particularly pressure vibrations from the hydraulic fluid in the vehicle's hydraulic system. Existing shock absorbers typically possess only one type of damping characteristic, and ordinary shock absorbers generally cannot reduce high-frequency vibrations. Because vehicles encounter various road conditions during operation, especially on unpaved roads, low-frequency and high-frequency vibrations alternate or occur simultaneously. This renders shock absorbers with only a single damping characteristic ineffective, especially when dealing with high-frequency vibrations, which can cause noticeable vibrations and thus reduce the user's driving experience.

[0003] Therefore, improving the vibration damping effect of shock absorbers under different frequency vibrations has become an urgent technical problem to be solved. Based on years of experience and practice in related industries, the inventor proposes a damping vibration reduction device and vehicle to overcome the shortcomings of existing technologies. Summary of the Invention

The stop member is provided with a second flow structure that connects the damping outer cavity and the damping inner cavity.

[0013] In a preferred embodiment of the present invention, the stop member includes a baffle plate, which is slidably sleeved on the support member and placed between the first elastic member and the second elastic member. The outer edge of the baffle plate is sealed to the sliding sleeve, and the baffle plate is provided with the second flow passage structure.

[0014] In a preferred embodiment of the present invention, the second flow-through structure includes at least one second flow-through hole disposed on the baffle; and / or, the second flow-through structure includes at least one second flow-through notch disposed on the edge of the baffle.

[0022] In a preferred embodiment of the present invention, the support member includes a support sleeve, the inner cavity of the support sleeve forms the medium outlet, the support sleeve is inserted into the damping cavity, and the support sleeve is connected to the housing through a limiting structure.

The first damping mechanism and the second damping mechanism set in the damping cavity can effectively absorb and filter the vibration of the working oil, especially high-frequency vibration, which significantly improves the damping and vibration reduction capability of the damping and vibration reduction device, helps to reduce vibration and impact on the vehicle, and thus improves the user's riding experience.

[0027] When faced with low-frequency vibrating working oil, the oil enters the damping chamber through the medium inlet and simultaneously impacts the first damping element. The first damping element overcomes the elasticity of the first elastic element and displaces. At the same time, some of the low-frequency vibrating working oil acts on the second damping element through the flow port, allowing it to also overcome the elasticity of the second elastic element and displace. Because the impact force of the low-frequency vibrating working oil is relatively small, the first and second damping elements can displace synchronously. The first flow structure remains closed, and the second and first damping elements remain sealed, with no change in damping.

[0028] When faced with high-frequency vibrating working oil, the high-frequency vibrating working oil enters the damping chamber through the medium inlet, and simultaneously impacts the first damping element and the second damping element. Furthermore, by differentially configuring the first damping element and the first elastic element, as well as the second damping element and the second elastic element, the high-frequency vibrating working oil, under instantaneous impact, causes the first damping element and the second damping element to produce different displacements. This causes the second damping element to disengage from the first damping element, opening the first flow passage structure. At this time, the high-frequency vibrating working oil can flow into the medium outlet and out through the first flow passage structure. Thus, through the cooperation of the first damping mechanism and the second damping mechanism, the high-frequency vibration of the working oil is significantly absorbed and filtered.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Implementation Method 1

[0040] Please refer to the following: Figure 1 As shown, an embodiment of the present invention provides a damping vibration reduction device, which includes at least a housing 100, a support member 200, a first damping mechanism 300, and a second damping mechanism 400. The housing 100 includes a damping cavity 110 and a medium inlet 120 communicating with the damping cavity 110. The support member 200 is disposed in the damping cavity 110 and connected to the housing 100, and the support member 200 is provided with a medium outlet 210 communicating with the damping cavity 110.

[0041] The first damping mechanism 300 is disposed in the damping cavity 110. The first damping mechanism 300 includes a first damping element 310 and a first elastic element 320. The first elastic element 320 is disposed on the support member 200. The first damping element 310 is slidably disposed between the first elastic element 320 and the medium inlet 120. The first damping element 310 is provided with an outlet 311 communicating with the medium inlet 120.

[0042] The second damping mechanism 400 is disposed within the first damping member 310. The second damping mechanism 400 includes a second damping member 410 and a second elastic member 420. The second elastic member 420 is disposed on the support member 200. The second damping member 410 is slidably disposed between the second elastic member 420 and the flow port 311. The second damping member 410 is provided with a first flow structure 411 connecting the flow port 311 and the medium outlet 210. Under the elastic force of the second elastic member 420, the second damping member 410 can be sealed and covered on the flow port 311.

[0043] Overall, when the damping and vibration reduction device is in use, the working oil can enter the damping cavity 110 inside the housing 100 through the medium inlet 120. The first damping mechanism 300 and the second damping mechanism 400 set in the damping cavity 110 can effectively absorb and filter both low-frequency and high-frequency vibrations of the working oil, which significantly improves the damping and vibration reduction capability of the damping and vibration reduction device, helps to reduce vibration and impact on the vehicle, and thus improves the user's riding experience.

[0044] When faced with low-frequency vibrating working oil, the low-frequency vibrating working oil enters the damping chamber 110 through the medium inlet 120. Simultaneously, the low-frequency vibrating working oil also impacts the first damping element 310, allowing it to overcome the elasticity of the first elastic element 320 and displace. At the same time, some of the low-frequency vibrating working oil acts on the second damping element 410 through the flow port 311, thus allowing the second damping element 410 to also overcome the elasticity of the second elastic element 420 and displace. Furthermore, because the impact force of the low-frequency vibrating working oil is relatively small, the first damping element 310 and the second damping element 410 can displace synchronously. The first flow structure 411 will not open, and the second damping element 410 remains sealed to the first damping element 310, with no change in damping.

[0045] When faced with high-frequency vibrating working oil, the high-frequency vibrating working oil enters the damping chamber 110 through the medium inlet 120, and simultaneously impacts the first damping element 310 and the second damping element 410. Furthermore, by differentially configuring the first damping element 310 and the first elastic element 320, as well as the second damping element 410 and the second elastic element 420, the high-frequency vibrating working oil, under instantaneous impact, causes the first damping element 310 and the second damping element 410 to generate different displacements. This causes the second damping element 410 to disengage from the first damping element 310, opening the first flow passage structure 411. At this time, the high-frequency vibrating working oil can flow into the medium outlet 210 and out through the first flow passage structure 411. Thus, through the cooperation of the first damping mechanism 300 and the second damping mechanism 400, the high-frequency vibration of the working oil is significantly absorbed and filtered.

[0046] This invention can significantly dampen and reduce vibrations in both low-frequency and high-frequency working oils simultaneously, without needing to consider the vibration characteristics of the working oil, thus offering better applicability. Designers can adjust the specific values ​​for low-frequency and high-frequency vibrations according to usage requirements; no specific numerical limitations are specified here.

[0047] In an embodiment of the present invention, the first damping member 310 includes a first end face and a second end face, which are disposed opposite to each other on both sides of the flow port 311; the first damping member 310 can be driven by the elastic force of the first elastic member 320 to abut against the medium inlet 120, and at least a portion of the first end face is disposed on the conveying path of the medium inlet 120; the second damping member 410 can abut against the second end face and seal the flow port 311 under the elastic force of the second elastic member 420.

[0048] Specifically, the flow port 311 extends through the first end face and the second end face. The first end face is positioned towards the medium inlet 120 and at least part of the first end face is positioned on the conveying path of the medium inlet 120. The second end face is positioned towards the second damping member 410, so that the second damping member 410 can seal against the flow port 311.

[0049] Designers can adjust the area of ​​the first end face on the conveying path of the medium inlet 120 and the size of the flow port 311 according to the needs of use, without making specific restrictions here.

[0050] The working oil flowing in through the medium inlet 120 can impact the first end face. The first damping element 310 can overcome the elastic force of the first elastic element 320 and drive the first end face away from the medium inlet 120, thereby playing a damping role.

[0051] Furthermore, the second damping element 410 can abut against the second end face and seal the flow port 311 through the second elastic element 420, allowing the working oil to impact the second damping element 410 through the flow port 311. Because the second damping element 410 can abut against the second end face and seal the flow port 311 under the elastic force of the second elastic element 420, when facing low-frequency vibrations, the oil has sufficient time to enter the damping inner cavity 112 from the outer damping cavity 111, thus making the pressure inside and outside the second damping element 410 equal, preventing it from being pushed away from the second end face. The second damping element 410 remains sealed to the first damping element 310, and the damping remains unchanged.

[0052] The high-frequency vibrating working oil has a large impact force, and the oil does not have enough time to enter the damping inner cavity 112 from the damping outer cavity 111. This creates a pressure difference across the second damping element 410, allowing the second damping element 410 to detach from the first damping element 310 and open the first flow passage structure 411. That is, the high-frequency vibrating working oil, under instantaneous impact, causes the first damping element 310 and the second damping element 410 to have different displacements, causing the second damping element 410 to detach from the first damping element 310. As a result, the working oil can flow in through the flow port 311, and then flow through the first flow passage structure 411 into the medium outlet 210 and out, thus achieving a venting effect.

[0053] In an embodiment of the present invention, the first damping member 310 divides the damping cavity 110 into at least a damping inner cavity 112 and a damping outer cavity 111. The first damping member 310 is provided with a second flow passage structure 313, which connects the damping inner cavity 112 and the damping outer cavity 111. The damping inner cavity 112 is connected to the first flow passage structure 411.

[0054] Specifically, when the first damping element 310 abuts against the medium inlet 120, the inner cavity of the first damping element 310 forms a damping inner cavity 112, and the outer wall of the first damping element 310 and the inner wall of the damping cavity 110 form a damping outer cavity 111.

[0055] By providing a second flow passage structure 313 on the first damping member 310, the second flow passage structure 313 can connect the damping inner cavity 112 and the damping outer cavity 111, and the damping inner cavity 112 is connected to the first flow passage structure 411 on the second damping member 410.

[0056] When the first damping element 310 moves within the damping cavity 110, the volume of the damping outer cavity 111 changes with the position of the first damping element 310. If the damping outer cavity 111 is sealed, the working oil within the damping outer cavity 111 will generate resistance, causing the first damping element 310 to be unable to move.

[0057] Therefore, in order to enable the first damping element 310 to move better and play a damping role, a second flow structure 313 is provided on the first damping element 310. The second flow structure 313 connects the damping inner cavity 112 and the damping outer cavity 111, so that when the volume of the damping outer cavity 111 decreases, the working oil in the damping outer cavity 111 can enter the damping inner cavity 112 along the second flow structure 313.

[0058] Furthermore, since the damping inner cavity 112 is connected to the first flow passage structure 411, the working oil can flow into the medium outlet 210 and out along the first flow passage structure 411. As a result, the working oil in the damping inner cavity 112 and the damping outer cavity 111 will not affect the damping effect of the first damping element 310 and the second damping element 410.

[0059] In an embodiment of the present invention, the first damping member 310 includes a sliding sleeve and a stop member 312. The inner cavity of the sliding sleeve forms a damping inner cavity 112, and the outer wall of the sliding sleeve forms a damping outer cavity 111 between the outer wall of the sliding sleeve and the housing 100. One end of the sliding sleeve is provided with a flow port 311, and the other end of the sliding sleeve is provided with a stop member 312. The sliding sleeve abuts against the first elastic member 320 through the stop member 312. The stop member 312 is provided with a second flow structure 313 that connects the damping outer cavity 111 and the damping inner cavity 112.

[0060] By providing a stop 312 at the other end of the sliding sleeve, the sliding sleeve can be slidably limited between the medium inlet 120 and the first elastic member 320, thereby improving the movement stability of the sliding sleeve in the damping cavity 110.

[0061] Specifically, the stop member 312 includes a baffle plate, which is slidably sleeved on the support member 200 and placed between the first elastic member 320 and the second elastic member 420. The outer edge of the baffle plate is sealed to the sliding sleeve, and the baffle plate is provided with a second flow passage structure 313.

[0062] Furthermore, at least one sealing ring 314 is provided on the outer wall of the sliding sleeve. The sealing ring 314 enables the sliding sleeve to form a piston structure within the damping cavity 110, thereby allowing the sliding sleeve to slide better within the damping cavity 110.

[0063] In one feasible embodiment, the second flow-through structure 313 includes at least one second flow-through hole disposed on the baffle. By providing the second flow-through hole on the baffle, the damping inner cavity 112 and the damping outer cavity 111 can be connected via the second flow-through hole.

[0064] Preferably, multiple second flow passages are provided, and these multiple second flow passages are arranged at intervals on the baffle, so that the baffle forms an orifice plate structure. Designers can adjust the specific number and position of the second flow passages according to the usage requirements, and no specific restrictions are imposed here.

[0065] In another feasible embodiment, the second flow-through structure 313 includes at least one second flow-through notch disposed on the edge of the baffle. By providing the second flow-through notch on the edge of the baffle, the damping inner cavity 112 and the damping outer cavity 111 can be connected by the second flow-through notch.

[0066] Of course, in other feasible embodiments, designers may adjust the specific construction of the second flow structure 313 according to the needs of use, and no specific restrictions are imposed here.

[0067] Furthermore, to prevent the first elastic element 320 from obstructing the second flow-through structure 313 and affecting the flow effect of the working oil, in an embodiment of the present invention, the first elastic element 320 is provided with a third flow-through structure. The third flow-through structure connects the second flow-through structure 313 and the damping outer cavity 111. The third flow-through structure includes at least one third flow-through hole and / or at least one third flow-through notch provided on the first elastic element 320.

[0068] In one feasible embodiment, the third flow-through structure includes at least one third flow-through hole disposed on the first elastic member 320. By providing the third flow-through hole on the first elastic member 320, the third flow-through hole can connect the damping outer cavity 111 and the second flow-through structure 313, thereby avoiding affecting the flow effect of the working oil.

[0069] In another feasible embodiment, the third flow-through structure includes at least one third flow-through notch disposed on the first elastic member 320. Preferably, the end of the first elastic member 320 has a throttling plate, and the third flow-through notch is disposed on the throttling plate at the end of the first elastic member 320.

[0070] Of course, in other feasible embodiments, designers may adjust the specific construction of the third flow structure according to the needs of use, and no specific restrictions are imposed here.

[0071] In an embodiment of the present invention, the second damping member 410 includes a third end face, which is disposed opposite to the second end face. Under the elastic action of the elastic member, the second damping member 410 can drive the third end face to abut against the second end face and seal the flow port 311.

[0072] Specifically, the second damping member 410 includes a sliding cover, one end of which is provided with a third end face, and the other end of the sliding cover abuts against the second elastic member 420. The first flow passage structure 411 is provided on the side wall of the sliding cover.

[0073] In an embodiment of the present invention, a sealing flange 412 is provided on the third end face. The sealing flange 412 is arranged around the periphery of the flow port 311. The sealing flange 412 can seal against the second end face and seal the flow port 311.

[0074] By providing a sealing flange 412 on the third end face, the sealing flange 412 can abut against the second end face to seal, thereby improving the sealing effect. Designers can adjust the specific shape of the sealing flange 412 according to the needs of use, such as setting the sealing flange 412 to be circular, elliptical, etc., without specific limitations.

[0075] Furthermore, in one feasible embodiment, the first flow-through structure 411 includes at least one first flow-through hole disposed on the sliding cover. By providing the first flow-through hole on the sliding cover, the damping inner cavity 112 and the medium outlet 210 can be connected through the first flow-through hole, thereby guiding the working oil.

[0076] Preferably, multiple first flow passages are provided, and the multiple first flow passages are spaced together and arranged in a ring on the side edge of the sliding cover. Designers can adjust the specific number and position of the first flow passages according to usage needs, and no specific restrictions are imposed here.

[0077] In another feasible embodiment, the first flow-through structure 411 includes at least one first flow-through notch disposed on the side edge of the slide cover. By providing the first flow-through notch on the slide cover, the first flow-through notch can also serve a communication function.

[0078] Of course, in other feasible embodiments, designers may adjust the specific construction of the first flow structure 411 according to the needs of use, and no specific restrictions are imposed here.

[0079] In an embodiment of the present invention, the first elastic member 320 includes a first elastic diaphragm, which is disposed on the outer wall of the support member 200, and the first elastic member 320 can abut against the first damping member 310.

[0080] Specifically, a first elastic diaphragm is ring-shaped on the support member 200, supporting the first damping member 310. Furthermore, when the first damping member 310 is impacted by working oil, it can push the first elastic diaphragm to deform, thereby adjusting its position to provide damping. When a stop member 312 is included, the first elastic diaphragm can connect with it.

[0081] Designers can adjust the specific structure and elasticity of the first elastic diaphragm according to the needs of use, without making specific restrictions here.

[0082] In an embodiment of the present invention, the second elastic member 420 includes a second elastic diaphragm, which is disposed on the outer wall of the support member 200, and the second elastic member 420 is capable of abutting against the second damping member 410.

[0083] Specifically, the second elastic diaphragm is ring-shaped on the support member 200 and spaced apart from the first elastic module, thereby supporting the second damping member 410. Furthermore, when the second damping member 410 is subjected to impact, it can push the second elastic diaphragm to deform, thereby adjusting the position of the second damping member 410 to achieve a damping effect.

[0084] An installation groove can be provided on the side edge of the second damping member 410, and the second elastic diaphragm can be snapped into the installation groove, which helps to improve the installation accuracy between the second damping member 410 and the second elastic diaphragm.

[0085] Designers can adjust the specific structure and elasticity of the first elastic diaphragm according to the needs of use, without making specific restrictions here.

[0086] In an embodiment of the present invention, the support member 200 includes a support sleeve, the inner cavity of the support sleeve forms a medium outlet 210, the support sleeve is inserted into the damping cavity 110, and the support sleeve is connected to the housing 100 through a limiting structure.

[0087] Specifically, at least part of the support sleeve is inserted into the damping cavity 110, and the support sleeve located in the damping cavity 110 can serve as the mounting base for the first and second elastic diaphragms. Designers can adjust the specific structure of the support member 200 according to the needs of use, and no specific restrictions are made here.

[0088] In an embodiment of the present invention, the limiting structure includes a limiting member 500, which connects the inner wall of the housing 100 and the outer wall of the support sleeve. Specifically, the limiting member 500 includes a limiting seat, which connects the inner wall of the housing 100 and the outer wall of the support sleeve. The support sleeve is inserted into the limiting seat, thereby the limiting member 500 can better fix the support sleeve and improve the installation stability of the support sleeve.

[0089] Of course, designers can adjust the specific workings of the limit component 500 according to the needs of use, and no specific restrictions are imposed here.
