[0091] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the present application.

[0092] According to a first aspect of the present application, a damper 100 is provided for being combined with an elastic element 11 to form at least part of a vehicle suspension, the damper 100 comprising: a connecting member 110 and a damping unit 120.

[0093] The connecting member 110 can be used to connect the damper 100 with a vehicle body to combine the damper 100 with the vehicle body. The damping unit 120 is arranged between the elastic element 11 and the connecting member 110; the damping unit 120 is used to provide a damping effect between the elastic element 11 and the vehicle body.

[0094] With the above scheme, by arranging the damper 100 to be connected with the elastic element 11, the vibration transmitted by the elastic element 11 can be attenuated. The damping unit 120 providing the damping effect is mounted to the vehicle body through the connecting member 110 and connected with the elastic element 11, so that the damping unit 120 can transmit the force between the vehicle body and the elastic element 11, i.e. provide a supporting effect to the vehicle body. In this way, the dead weight of the vehicle body is applied to the elastic element 11 from the damping unit, and the vibration transmitted by the elastic element 11 can be fully processed and attenuated by the damping unit 120, rather than being transmitted to the damping unit by using resonance or other means. This ensures the damping effect of the damping unit on the vibration energy, and at the same time enables the damping unit to provide a supporting effect to the vehicle body.

[0095] In some embodiments, the damping unit 120 comprises a first seat body 121. The connecting member 110 comprises a second seat body 111. The first seat body 121 is connected with the elastic element 11 to form a connection capable of transmitting force, such as a mechanical connection. The second seat body 111 is movably connected with the first seat body 121. The first seat body 121 and the second seat body 111 jointly form a containing space 120a containing fluid. In this way, since the containing space 120a is formed between the first seat body 121 and the second seat body 111, the containing space 120a can be filled with fluid. During the relative movement of the first seat body 121 and the second seat body 111, the vibration energy is at least partially transmitted to the fluid by using the flow / or change of the fluid in the containing space 120a, and the fluid at least absorbs this part of the energy, so that the vibration transmitted by the first damper 100 to the vehicle body is further reduced, and the shock absorption performance of the damper 100 is improved.

[0096] In a specific solution, the fluid filled in the accommodating space 120a is gas, and energy is absorbed by the change of the gas.

[0097] In another specific embodiment, the accommodating space 120a may also be filled with liquid.

[0098] In some embodiments, the damping unit 120 further includes a flow channel skeleton 122. The flow channel skeleton 122 is disposed within the accommodating space 120a and defines a fluid channel 122a for the fluid in the accommodating space 120a. The flow channel skeleton 122 is disposed between the first base 121 and the second base 111, such that the fluid channel 122a connects to one side of the first base 121 and the other side of the second base 111. In a specific embodiment, liquid can flow in the fluid channel 122a. With this arrangement, when the first base 121 and the second base 111 move relative to each other, the liquid absorbs vibration energy. Simultaneously, as the liquid flows through the fluid channel 122a, it rubs against the walls forming the fluid channel 122a, converting the energy into heat. This energy is dissipated through the wall thickness of the flow channel skeleton 122, achieving attenuation during energy transfer and enhancing shock absorption. In this embodiment, the damping unit 120 can be considered a hydraulic bushing integrated with the elastic element 11, capable of providing vibration damping using flowing liquid.

[0099] In some embodiments, the first seat 121 is provided with: a first elastic buffer 123. The first elastic buffer 123 is at least partially provided in the accommodating space 120a and is located between the first seat 121 and the flow channel skeleton 122, so that the fluid channel 122a is connected to the first elastic buffer 123. The first elastic buffer 123 is made of a material with plastic deformation ability, such as rubber. When the first seat 121 and the second seat 111 move relative to each other due to external impact, the liquid in the accommodating space 120a is squeezed, and the hydraulic pressure forces the first elastic buffer 123 to undergo plastic deformation, thereby enabling the liquid to flow in the fluid channel 122a, thereby achieving the function of attenuating vibration energy. Of course, when the external impact disappears, the deformation of the first elastic buffer 123 can be restored to prepare for the next shock absorption.

[0100] In some embodiments, the second seat body 111 is provided with a second elastic buffer 124. The second elastic buffer 124 is at least partially arranged in the accommodating space 120a and between the second seat body 111 and the flow channel framework 122, so that the fluid channel 122a is communicated to the second elastic buffer 124. Similar to the first elastic buffer 123, the second elastic buffer 124 can also be made of a material with plastic deformation capacity, such as rubber. Thus, by arranging the first elastic buffer 123 and the second elastic buffer 124, when the vibration is transmitted to the first seat body 121 or the second seat body 111, the liquid in the accommodating space 120a flows between the first elastic buffer 123 and the second elastic buffer 124 through the deformation and recovery of the first elastic buffer 123 and the second elastic buffer 124, and further realizes the damping effect of the vibration.

[0101] In some embodiments, a plurality of flow distribution cavities 120b are formed on the first elastic buffer 123, and the flow distribution cavities 120b are communicated with the fluid channel 122a; and / or a plurality of flow distribution cavities 120b are formed on the second elastic buffer 124, and the flow distribution cavities 120b are communicated with the fluid channel 122a. The flow distribution cavities 120b are communicated with the fluid channel 122a. The arrangement of the flow distribution cavities 120b can make the fluid more uniformly distributed around the first elastic buffer 123 and / or the second elastic buffer 124, so as to be able to provide a relatively stable damping effect on the vibration transmitted to each local position of the first elastic buffer 123 and / or the second elastic buffer 124.

[0102] As a specific scheme, when the first seat body 121 and the second seat body 111 relatively move, the first elastic buffer 123 and / or the second elastic buffer 124 are deformed due to the pressure of the liquid, so as to form spaces between the first elastic buffer 123 and the flow channel framework 122, and / or between the second elastic buffer 124 and the flow channel framework 122, which are respectively referred to as a first flow channel 120c and a second flow channel 120d. It can be understood that the first flow channel and the second flow channel are part of the accommodating space 120a and can be passed through by the liquid. And when the first seat body 121 and the second seat body 111 relatively move, the size of the space of the first flow channel and the second flow channel changes due to the deformation of the first elastic buffer 123 and the second elastic buffer 124, and the size change trend of the first flow channel and the second flow channel is opposite, so that the liquid can flow between the first flow channel and the second flow channel during the size change of the first flow channel and the second flow channel, and the damping effect is realized.

[0103] In some embodiments, the flow channel skeleton 122 forms a wall of the fluid passage extending at least in a first direction X1 different from a direction in which the first seat 121 moves relative to the second seat 111. For example, the first seat 121 can slide relative to the second seat 121 in the first direction X1, and the fluid passage extends in a direction different from the first direction X1 for a distance. That is, the liquid flows in the fluid passage 122a between the first seat 121 and the second seat 111 not in the shortest path, so that the heat generated by the friction between the liquid and the wall of the fluid passage 122a formed by the flow channel skeleton 122 is increased by increasing the travel distance of the liquid, so as to improve the damping efficiency of the vibration energy.

[0104] In specific embodiments, the wall of the fluid passage 122a formed by the flow channel skeleton 122 includes a first communication section 122b, a second communication section 122c, and an intermediate communication section 122d.

[0105] The first communication section 122b is formed on a side of the flow channel skeleton 122 close to the first seat 121 so that the fluid passage 122a communicates with the first seat 121 at the first communication section 122b; the second communication section 122c is formed on a side of the flow channel skeleton 122 close to the second seat 111 so that the fluid passage 122a communicates with the second seat 111 at the second communication section 122c; the intermediate communication section 122d is formed between the first communication section 122b and the second communication section 122c to connect the first communication section 122b and the second communication section 122c; and the intermediate communication section 122d is arranged in a direction different from the first direction X1 at one end connected to the first communication section 122b and at one end connected to the second communication section 122c. For example, the intermediate communication section 122d is arranged in a direction perpendicular to the first direction X1 at one end connected to the first communication section 122b and at one end connected to the second communication section 122c. Thus, the liquid can flow in the intermediate communication section 122d for a distance between the first seat 121 and the second seat 111, so that the heat generated by the friction between the liquid and the flow channel skeleton 122 is increased at least in the intermediate communication section 122d, thereby damping the vibration energy.

[0106] In some embodiments, a sealing member 125 is arranged on the first seat 121 and / or the second seat 111, and the sealing member 125 is in contact with the flow channel skeleton 122 to form a seal. The sealing member 125 is, for example, a rubber sealing ring, which is nested between the flow channel skeleton 122 and the first seat 121, or between the flow channel skeleton 122 and the second seat 111, or both between the flow channel skeleton 122 and the first seat 121 and between the flow channel skeleton 122 and the second seat 111, so as to seal the fluid passage 122a by the sealing member 125 to prevent liquid leakage.

[0107] In specific embodiments, the first seat body 121 and the second seat body 111 can be made of reinforced plastic or aluminum alloy to ensure that the damping unit 120 meets the strength requirements during operation.

[0108] In some embodiments, the damping unit 120 further comprises a first spacer 126. The first spacer 126 is arranged on the side of the damping unit 120 close to the elastic element 11. When the damper 100 is combined with the elastic element 11, the first spacer 126 is arranged between the damping unit 120 and the elastic element 11 to separate the damping unit 120 from the elastic element 11. In specific embodiments, the first spacer 126 is, for example, a rubber pad arranged between the first seat body 121 and the shock absorbing spring 11a. The first spacer 126 is fixedly connected to the first seat body 121, for example, by gluing, to separate the first seat body 121 from the shock absorbing spring 11a and reduce the wear of the first seat body 121 and the shock absorbing spring 11a. At the same time, the first spacer 126 can also be used to buffer vibrations, thereby further improving the shock absorbing performance.

[0109] According to a second aspect of the present application, a shock absorbing assembly 10 is provided, which comprises the above-mentioned damper 100 and an elastic element 11 connected to the damper 100. The shock absorbing assembly 10 has all the advantages of the above-mentioned damper, which will not be repeated here.

[0110] In some embodiments, the elastic element 11 comprises a shock absorbing spring 11a abutting against the damping unit 120. Alternatively, in other embodiments, the elastic element 11 can comprise, for example, an air spring. Taking the configuration of the elastic element 11 as an example, the shock absorbing spring 11a arranged between the damping unit 120 and the linear motor 12 can be used to provide elastic force between the vehicle body and the vehicle wheel to provide elastic support to the vehicle body.

[0111] When the shock absorbing assembly 10 of the present application is integrated for use on a vehicle, it can be used as at least part of the suspension of the vehicle to provide shock absorption between the vehicle wheel and the vehicle body. At this time, by further configuring the structure of the shock absorbing assembly 10, the suspension can be configured as a passive suspension or an active suspension. In the following, some exemplary structures and connection relationships of the shock absorbing assembly 10 when the shock absorbing assembly 10 is configured as at least part of an active suspension will be mainly described to further illustrate the inventive concept of the present application.

[0112] In some embodiments, the shock absorbing assembly 10 further comprises an actuator. The actuator is used to adjust the stiffness of the elastic element 11. For example, when the shock absorbing assembly 10 is integrated between the vehicle body and the vehicle wheel of a vehicle, the stiffness of the elastic element 11 is adjusted by the actuator to adjust the ability of the shock absorbing assembly 10 to adjust the amplitude of the change in the distance between the vehicle wheel and the vehicle body when subjected to external impact. The elastic element 11 is connected to one part of the actuator, and the damping unit 120 is connected to another part of the actuator.

[0113] In some embodiments, the actuator comprises a linear motor 12. The linear motor 12 has a mover and a stator 13. The mover and the stator 13 work by electromagnetic induction. In brief, when the linear motor 12 works, the stator 13 is powered to generate a changing magnetic field, which enables the mover to slide relative to the stator 13. The specific cooperation between the mover and the stator 13 is not described herein. The mover is not shown in the drawings of the present application. In optional solutions, the stator 13 can be connected with the damping unit 120. Specifically, the stator 13 is fixedly connected with the first seat body 121.

[0114] The elastic element 11 can be arranged to be at least partially mounted outside the mover. In specific solutions, the shock-absorbing spring 11a is at least partially mounted outside the mover. Meanwhile, the damping unit 120 is at least partially mounted outside the stator 13.

[0115] Since the damping unit 120 works without relying on a large storage amount of fluid in the accommodating cavity 14a to provide a good shock-absorbing effect, only a relatively small amount of liquid needs to be configured, and the shock-absorbing is completed by the flow of the liquid. Therefore, the size of the damping unit 120 can be relatively small, and the overall size of the damper 100 can be controlled to be relatively small, which is convenient for integration into a vehicle or other equipment. Moreover, the elastic element 11 and the damping unit 120 are arranged outside the linear motor 12, which does not occupy the actuation stroke of the linear motor 12. The assembly precision requirement and assembly difficulty of each part of the shock-absorbing assembly 10 are relatively lower.

[0116] In some embodiments, the linear motor 12 further comprises a housing 14. The housing 14 is used to position and mount the mover and the stator 13, so as to realize the positioning cooperation between the mover and the stator 13 by using the housing 14. As a specific solution, the housing 14 has an accommodating cavity 14a formed inside, and the stator 13 can be at least partially arranged in the accommodating cavity 14a, so as to protect the stator by using the housing 14. In a more specific solution, the stator 13 is in sliding connection with the housing 14, and the sliding direction X3 of the stator 13 is guided by the inner wall of the accommodating cavity 14a. The mover is fixedly arranged in the accommodating cavity 14a. The elastic element 11 is located outside the accommodating cavity 14a.

[0117] In some embodiments, the damping assembly 10 further comprises a second spacer 15. The second spacer 15 is disposed outside the housing 14. The second spacer 15 is disposed between the elastic element 11 and the housing 14 to separate the elastic element 11 and the housing 14. Similar to the first spacer 126, the second spacer 15 is made of rubber or the like, and provides cushioning between the housing 14 and the damping spring 11a. The second spacer 15 can be made of various materials having elastic deformation capability. The second spacer 15 separates the housing 14 and the damping spring 11a, and reduces the wear of the housing 14 and the damping spring 11a during use.

[0118] As an exemplary scheme of the specific cooperation between the housing 14 and the second spacer 15, the housing 14 is provided with a limiting portion 14b. The limiting portion 14b protrudes from the outer wall of the housing 14 in a second direction X2 different from the sliding direction X3 of the mover. It should be understood that the sliding direction of the mover is the sliding direction of the mover relative to the stator 13, which can be opposite to the sliding direction of the stator 13 relative to the housing 14. The second spacer 15 is disposed between the limiting portion 14b and the damping spring 11a. In this way, the second spacer 15 separates the damping spring and the housing 14, reducing the wear of the damping spring and the housing 14, and the limiting portion 14b protruding from the surface of the housing 14 provides support or limiting for the damping spring, so that the damping spring can elastically deform when subjected to external impact.

[0119] As a specific scheme, the damper 100 further comprises a fork arm 16. The fork arm 16 is connected to the linear motor 12, and the specific connection manner is, for example, that the fork arm 16 is fixedly connected / integrally formed with the housing 14. The fork arm 16 and the damping unit 120 are respectively disposed at opposite ends of the linear motor 12. In actual use, the fork arm 16 and the damping unit 120 can be respectively connected to two different parts of the equipment to be damped, so as to provide damping function between the two different parts by using the damper 100. For example, when the damper 100 is integrated on a vehicle as at least part of the active suspension, the fork arm 16 can be connected to the vehicle body, and the damping unit 120 can be connected to the vehicle wheel, so as to provide damping between the vehicle wheel and the vehicle body.

[0120] It can be understood that although the damping unit 120 is described as being connected to the wheel, the damping unit 120 does not have to be directly connected to the wheel, but can also be connected to the wheel shaft, the axle on which the wheel is installed, or the like. Accordingly, the connecting member 110 can further include an end cover 112. The end cover 112 is arranged on the side of the damping unit 120 away from the seat body, and in a specific scheme, the end cover 112 is fixedly connected to the side of the second seat body 111 away from the first seat body 121, and can be connected to the vehicle body. The end cover 112 can be used to separate the second seat body 111 from the vehicle body. Avoiding direct contact between the second seat body 111 and the vehicle body, considering that the second seat body 111 needs to be precisely matched with the first seat body 121 to ensure the sealing of the accommodating space, the second seat body 111 and the end cover can be made with different machining accuracies. For example, the second seat body can be arranged on a part that has been subjected to precision machining to improve the surface accuracy, so that the second seat body can be precisely matched with the first seat body 121, and the end cover can be arranged to protect the second seat body 111 to reduce wear thereof. As a specific scheme, the end cover 112 is connected to the second seat body 111, the shell 14 is connected to the first seat body 121 through the shock-absorbing spring 11a and the first spacer 126, so that the end cover 112 and the shell 14 can move relatively, and the end cover 112 is connected to the vehicle body, and the shell 14 is connected to the wheel through the fork arm 16, so that when the wheel moves relatively with the vehicle body due to road impact or the like, at least the damping unit 120 is used to attenuate the vibration energy in the relative movement of the end cover 112 and the shell 14.

[0121] It should be noted that although the linear motor 12 is used as an example in the embodiment to illustrate that the shock-absorbing assembly 10 can be used as at least part of the active suspension, at this time the shock-absorbing assembly 10 can also be referred to as a shock absorber, and the main feature of the shock absorber when used as an active suspension is that the stiffness of the shock absorber can be adjusted.

[0122] According to actual use, a person skilled in the art can also use a rotary motor and a transmission structure such as a lead screw to realize the movement of the movable part connected to the transmission structure relative to the rotary motor, so that the part connected to the movable part can move relative to the rotary motor, and then the stiffness of the damper is adjusted. At this time, the rotary motor and the transmission structure such as the lead screw are equivalent to the stator 13 of the linear motor 12 in the function of adjusting the stiffness of the damper 100, and the movable part is equivalent to the combination of the mover of the linear motor 12, the housing 14 and other structures. Based on this, the linear motor 12 in the present application can be taken as a specific example of an adjusting device for adjusting the size of the damper 100 in the damping direction (in a specific scheme, for example, the length of the part of the stator 13 extending out of the accommodating cavity 14a is adjusted). The linear motor 12 in the present application is not the only limitation on the specific structure of the adjusting device, but should be regarded as an exemplary description of its structure. For the scheme in which the elastic element 11 and the damping unit 120 are integrated on other types of adjusting devices to be integrated into a part of the active suspension, it should be regarded as within the protection scope of the present application.

[0123] According to the second aspect of the present application, a vehicle 1 is provided, comprising the above-mentioned damper 100, or comprising the above-mentioned damping assembly 10. The vehicle 1 has all the beneficial effects of the above-mentioned damper 100 or damping assembly 1, and the present application will not be described here.

[0124] The vehicle 1 can be a fuel automobile, a plug-in hybrid electric vehicle or a new energy vehicle, and the present application does not make specific limitations thereon.

[0125] In the description of the present application, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0126] In the above embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0127] The embodiments, implementation manners and related technical features of the present application can be combined, replaced with each other without conflict.

[0128] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present application, without departing from the technical solution content of the present application, still belongs to the scope of the technical solution of the present application.
