In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Reference below Figure 1-Figure 3 A vibration absorber 100 according to an embodiment of the present invention is described. The vibration absorber 100 can be used to achieve vibration absorption, and control signals can be transmitted and received between the vibration absorber 100 and the control module by wireless transmission, that is, the setting of the connecting wire harness between the vibration absorber 100 and the control module is reduced, which is beneficial to reducing the setting cost of the vibration absorber 100 and reducing the limitation of the installation space of the vibration absorber 100.

[0043] like Figure 1-Figure 3 As shown, a vibration absorber 100 according to an embodiment of the present invention includes: a vibration absorbing structure, a motor structure and a wireless receiving module 4. It should be noted that the vibration absorber 100 of the present invention can be installed on a device to be vibration-absorbed, such as the vibration absorber 100 can be installed on a sub-frame of a vehicle, so that the vibration energy on the sub-frame can be absorbed by the vibration absorber 100, the vibration of the whole vehicle can be reduced, and the riding comfort of the user can be improved.

[0044] The vibration absorbing structure includes a reciprocating part, a hydraulic cavity is formed in the vibration absorbing structure, and the motor structure is connected to the reciprocating part to drive the reciprocating part to drive the liquid in the hydraulic cavity to reciprocate. Therefore, when the motor structure is energized, the reciprocating part can be driven to reciprocate, that is, the reciprocating part can be pushed to reciprocate in two opposite directions, such as pushing the reciprocating part to reciprocate in a linear direction, so as to push the liquid in the hydraulic cavity during the linear motion.

[0045] The reciprocating part can be used to cooperate with other structures to define a hydraulic cavity, or to be connected to a structure that defines a hydraulic cavity, so that when the reciprocating part performs linear motion, the space in the hydraulic cavity can change reciprocatingly, thereby enabling the liquid in the hydraulic cavity to perform reciprocating motion. Therefore, when the vibration absorber 100 is installed on the vibration-absorbing device, the motor structure can be controlled to drive the reciprocating part, so as to utilize the reciprocating flow of the liquid in the hydraulic cavity to actively absorb the vibration energy on the vibration-absorbing device, that is, the reverse consumption of the liquid motion force and the vibration force can be utilized to reduce the vibration effect.

[0046] Furthermore, the vibration absorber 100 is provided with a wireless receiving module 4, and the wireless receiving module 4 is electrically connected to the motor structure, and the wireless receiving module 4 is suitable for controlling the operation of the motor structure after receiving the control signal. It should be noted that the wireless receiving module 4 can be used in conjunction with the wireless transmitting module, that is, a control module can be set, and the control module includes a wireless transmitting module, so as to send a control signal to the wireless receiving module 4 through the wireless transmitting module, and then actively control the working state of the motor structure to achieve active vibration absorption. Among them, wireless transmission technology can be used for signal transmission between the wireless receiving module 4 and the wireless transmitting module, that is, there is no need to set a connecting harness for signal transmission between the vibration absorber 100 and the control module, thereby reducing the setting of the connecting harness and reducing the setting cost of the vibration absorber 100.

[0047] At the same time, when the shock absorber 100 and the control module cooperate through wireless control, the installation position of the shock absorber 100 is not limited by the installation position of the control module, and the two can be set at relatively far relative positions. Therefore, when the shock absorber 100 is installed on the vehicle body, there is no need to consider the installation position of the control module, which is beneficial to reduce the limitation of the shock absorber 100 on the installation space and facilitate the layout of the entire vehicle.

[0048] According to the vibration absorber 100 of the embodiment of the present invention, by providing the wireless receiving module 4 in the vibration absorber 100, wireless signal transmission can be performed between the vibration absorber 100 and the control module, so that the vibration absorbing function of the vibration absorber 100 can be wirelessly controlled, thereby reducing the setting of the connection harness required for the vibration absorber 100, reducing the setting cost of the vibration absorber 100, and allowing the vibration absorber 100 to be installed without being restricted by the installation space, thereby reducing the difficulty of installing the vibration absorber 100.

[0049] In some embodiments, Figure 1 As shown, the vibration absorber 100 further includes a shell frame, which defines an installation cavity, and the vibration absorbing structure and the motor structure are both installed in the shell frame. Therefore, the shell frame can provide installation support for the vibration absorbing structure and the motor structure, and protect the vibration absorbing structure and the motor structure, that is, the vibration absorbing structure and the motor structure can be arranged in the installation cavity to prevent the transmission between the motor structure and the vibration absorbing structure from being affected by the outside of the vibration absorber 100, thereby ensuring that the vibration absorber 100 operates reliably.

[0050] Among them, after the vibration absorption structure and the motor structure are installed in the shell frame, they can be relatively fixed to the shell frame, such as by interference fit, connection with connectors or limited fixation through a limiting structure, and the fixing method is flexible and optional.

[0051] In addition, the shell frame can be made of metal material so that the shell frame has strong structural strength and stability, thereby ensuring that the overall structural strength of the vibration absorber 100 is relatively large, avoiding serious structural deformation of the vibration absorber 100 when it is impacted by external force, improving the structural safety of the vibration absorber 100, and ensuring the operating reliability of the vibration absorbing structure and the motor structure.

[0052] like Figure 1 As shown, the wireless receiving module 4 is located outside the shell frame, that is, the wireless receiving module 4 can be installed on the outside of the shell frame, so that when the wireless receiving module 4 and the wireless transmitting module are transmitting signals, the shell frame will not block the transmission signal. It should be noted that the shell frame is made of metal material, and the wireless receiving module 4 is arranged outside the shell frame to avoid the shielding layer formed by the shell frame affecting the signal reception of the wireless receiving module 4, thereby improving the accuracy and reliability of the wireless signal reception of the wireless receiving module 4.

[0053] In some embodiments, the wireless receiving module 4 is electrically connected to the motor structure through the electrical connection part 41, the housing frame is provided with an avoidance hole, and the electrical connection part 41 is passed through the avoidance hole. Figure 1 As shown, the wireless receiving module 4 is arranged on the outside of the shell frame, and the shell frame is provided with an avoidance hole open toward the wireless receiving module 4, and the wireless receiving module 4 and the motor structure can be electrically connected through the electrical connection part 41 penetrating the avoidance hole. Therefore, when the wireless receiving module 4 receives the control signal, the wireless receiving module 4 can generate a control instruction, and output the control instruction to the motor structure through the electrical connection part 41 to actively control the motor structure, or a vibration absorber 100 power supply is provided at the wireless receiving module 4, and when the wireless receiving module 4 receives the control signal, the vibration absorber 100 power supply can be controlled to be connected to the motor structure through the electrical connection part 41, thereby realizing the power supply and control of the motor structure.

[0054] Therefore, the motor structure and the wireless receiving module 4 can be respectively arranged on the inner and outer sides of the shell frame, which not only ensures that the motor structure is in a stable and reliable working environment, but also facilitates the wireless receiving module 4 to accurately receive the control signal, and also ensures that the wireless receiving module 4 can effectively control the motor structure, thereby realizing wireless control of the vibration absorber 100.

[0055] In some embodiments, Figure 1 As shown, the housing frame includes a first housing 31 and a second housing 32, which are connected along the moving direction of the reciprocating part and define a mounting cavity together. That is, the first housing 31 and the second housing 32 are independent structural members, that is, the housing frame is a split structure, so that the first housing 31 and the second housing 32 can be formed separately, thereby reducing the difficulty of forming the housing frame and reducing the setting cost.

[0056] Among them, the vibration absorbing structure is located in the first shell 31, and the motor structure is located in the second shell 32. That is, when installing the vibration absorbing structure and the motor structure, the vibration absorbing structure and the motor structure can be installed separately. For example, the motor structure can be installed in the second shell 32 first, and then the vibration absorbing structure can be connected to the motor structure, and finally the first shell 31 can be connected to the second shell 32, so that the vibration absorbing structure can be accommodated in the first shell 31, which is conducive to reducing the difficulty of installation.

[0057] Also, it should be noted that the first shell 31 and the second shell 32 can be installed in the up and down direction, and the movement direction of the reciprocating part is the up and down direction, that is, the first shell 31 is connected to the top of the second shell 32. In other words, the vibration absorbing structure can be installed above the motor structure, that is, the hydraulic chamber is located above the motor structure, thereby, the motor structure can push the reciprocating part to move upward, and when the reciprocating part moves downward, it can be driven by the motor structure, or it can move under the action of gravity, that is, the power consumption of driving the reciprocating part is reduced.

[0058] like Figure 1 As shown, the wireless receiving module 4 is installed on the outside of the second housing 32, the wireless receiving module 4 and the second housing 32 are spaced apart and distributed in the horizontal direction, and a evacuation hole is provided in the second housing 32, and the electrical connection part 41 passes through the evacuation hole of the second housing 32 to be connected with the wireless receiving module 4 and the motor structure respectively. In this way, the distance between the motor structure and the wireless receiving module 4 can be shortened, that is, the length of the electrical connection part 41 can be shortened, and the installation cost can be reduced.

[0059] In some embodiments, the housing frame further includes a mounting shell 33, the mounting shell 33 is located in the second housing 32, and the motor structure is mounted in the mounting shell 33. Figure 1As shown, a cavity is formed in the mounting shell 33, and the motor structure is fixedly mounted in the mounting shell 33, so that the mounting shell 33 and the second shell 32 can both protect the motor structure. The mounting shell 33 is connected to the vibration absorbing structure, such as Figure 1 As shown, the vibration absorbing structure is supported above the mounting shell 33 and is relatively fixed to the mounting shell 33 .

[0060] In some embodiments, a limit mounting groove 34 protruding outward is formed on the inner side of the connection between the first shell 31 and the second shell 32, and the vibration absorbing structure and / or the mounting shell 33 are provided with a limit flange portion, which is inserted into the limit mounting groove 34 to cooperate with the limit mounting groove 34 in a limit position along the movement direction of the reciprocating part, thereby realizing the limit fixation of the first shell 31, the second shell 32, the vibration absorbing structure and the mounting shell 33.

[0061] like Figure 1 As shown, the first shell 31 is connected to the second shell 32 in the up and down direction, and a first connecting flange 311 is formed at the edge of the lower end of the first shell 31, and the first connecting flange 311 defines a limiting mounting groove 34 open inwardly. At the same time, a second connecting flange 321 is formed at the edge of the upper end of the second shell 32, and the second connecting flange 321 extends into the limiting mounting groove 34, and limiting flange portions are formed at the outer peripheral edge of the vibration absorbing structure and the outer peripheral edge of the mounting shell 33. Thus, the limiting flange portion of the vibration absorbing structure, the limiting flange portion of the mounting shell 33 and the second connecting flange 321 are overlapped and jointly inserted into the limiting mounting groove 34, thereby realizing the limiting fixation between the motor structure, the vibration absorbing structure and the shell frame, so that the vibration absorber 100 forms an integral structure and realizes compact installation between the various components.

[0062] Specifically, a shell flange 331 extending outward is provided at the upper edge of the installation shell 33. The shell flange 331 is constructed as a limiting flange portion for limiting cooperation with the limiting installation groove 34 to achieve limited installation of the installation shell 33 and the first shell 31 and the second shell 32. The structure is simple and the installation is convenient.

[0063] In some embodiments, the motor structure includes a stator part and a mover part, the stator part includes an electromagnetic coil 22, the mover part includes a magnet 24 inductively matched with the electromagnetic coil 22, the electromagnetic coil 22 is electrically connected to the wireless receiving module 4, the wireless receiving module 4 is used to control the power-on state of the electromagnetic coil 22, the mover part is connected to the reciprocating part, and the stator part is used to drive the mover part to drive the reciprocating part to perform reciprocating motion, thereby, the reciprocating part can push the liquid in the hydraulic chamber to reciprocate to perform a vibration absorption effect.

[0064] Specifically, the stator part includes a stator body 21 and an electromagnetic coil 22, the electromagnetic coil 22 is wound around the stator body 21, and the electromagnetic coil 22 is electrically connected to the wireless receiving module 4 through the electrical connection part 41, and the wireless receiving module 4 can control the power supply of the electromagnetic coil 22 and control the current flow direction of the electromagnetic coil 22, wherein the stator body 21 and the electromagnetic coil 22 can be relatively fixed by the fixing plate 25. At the same time, the mover part includes a mover body 23 and a magnet 24, and the electromagnetic coil 22 cooperates with the magnet 24 inductively when powered on to generate a driving force to drive the mover body 23 to move, and the mover body 23 is connected to the reciprocating part, thereby driving the reciprocating part to reciprocate.

[0065] In other words, the vibration absorber 100 of the present invention is of a motor type, and the reciprocating part is driven by the motor to drive the liquid to reciprocate, so that a damping force is provided during the reciprocating flow of the liquid. This damping force makes the output force of the vibration absorber 100 more stable, and has the characteristics of a wider frequency band range at the peak and valley of the output force, and a better vibration absorption effect; at the same time, the motor-type vibration absorber 100 can generate a composite motion of multiple frequency components at the same time by input voltage control, and when this type of vibration absorber 100 is used on a whole vehicle, the vibration absorption ability is stronger; and, Figure 2 As shown, the traditional electromagnetic coil 22 type active vibration absorber 100 has a nonlinear relationship between the input voltage and the output force. No matter how the input voltage changes, it can only produce unidirectional motion and is unidirectionally controllable, and the damping characteristic is low. However, the input voltage and output force of the vibration absorber 100 in the present invention have a linear relationship, and bidirectional reciprocating motion can be achieved.

[0066] In some embodiments, the stator part is arranged around the mover part, that is, the stator part can be constructed as an annular structure, and the mover part is inserted into the stator part. The mover part can reciprocate along the axial direction of the stator part, so that the mover part pushes the reciprocating part to drive the liquid to flow reciprocatingly.

[0067] Among them, the electromagnetic coil 22 can be arranged to be distributed around the movable part, and the magnet 24 can also be arranged in plurality, and the plurality of magnets 24 are distributed around the movable part, and then through the cooperation of the electromagnetic coil 22 and the plurality of magnets 24, each position of the movable part in the circumferential direction can be pushed by force at the same time, thereby improving the output force.

[0068] In some embodiments, the vibration absorption structure includes a hydraulic module and an elastic module 13, which are connected to each other. The hydraulic chamber includes a first chamber 141 and a second chamber 142 that are connected. The first chamber 141 is formed in the hydraulic module, and the second chamber 142 is formed between the elastic module 13 and the hydraulic module. At least part of the elastic module 13 is constructed as a reciprocating part, and the reciprocating part is used to push the liquid to reciprocate between the first chamber 141 and the second chamber 142. In other words, during the movement of the reciprocating part, the liquid can be pushed from the first chamber 141 to the second chamber 142, or from the second chamber 142 to the first chamber 141, thereby generating a vibration damping force during the reciprocating flow of the liquid.

[0069] Specifically, Figure 1 As shown, the hydraulic module is arranged above the elastic module 13, and a first cavity 141 is arranged inside the hydraulic module, and a second cavity 142 is arranged between the elastic module 13 and the hydraulic module, and the second cavity 142 is arranged below the first cavity 141, and the first cavity 141 and the second cavity 142 can pass through each other, that is, the liquid can flow upward into the first cavity 141, and can also flow downward into the second cavity 142. That is, during the movement of the reciprocating part, when the reciprocating part moves upward, the liquid in the second cavity 142 flows upward into the first cavity 141 under the action of the reciprocating part, and when the reciprocating part moves downward, the liquid in the first cavity 141 flows downward into the second cavity 142 under the action of the reciprocating part, thereby realizing the reciprocating flow of the liquid.

[0070] In this way, the reciprocating flow of the liquid can be realized, and the damping and vibration absorbing effect can be achieved during the flow process.

[0071] In some embodiments, the hydraulic module includes a leather cup assembly 11 and a flow channel assembly 12. The leather cup assembly 11 is connected to the side of the flow channel assembly 12 away from the elastic module 13. The leather cup assembly 11 and the flow channel assembly 12 define a first cavity 141, and the flow channel assembly 12 and the elastic module 13 define a second cavity 142, thereby defining two interconnected cavities for reciprocating flow of liquid.

[0072] Specifically, Figure 1 As shown, the cup assembly 11 is disposed above the flow channel assembly 12, and the flow channel assembly 12 is disposed above the elastic module 13, so that the first cavity 141 is located above the second cavity 142. The cup assembly 11 can be provided so that the volume of the second cavity 142 can gradually increase or decrease under the action of the pressure in the second cavity 142 to adapt to the movement of the reciprocating part.

[0073] It should be noted that at least part of the elastic module 13 is constructed as a reciprocating part, and the reciprocating part is suitable for moving toward the second cavity 142, or moving in a direction away from the second cavity 142, so as to achieve a change in the volume of the second cavity 142. The first cavity 141 is defined by the leather cup assembly 11 and the flow channel assembly 12. The leather cup assembly 11 includes an elastic part, which allows the first cavity 141 to change with the change in the volume of the second cavity 142.

[0074] Specifically, when the reciprocating part moves upward, the volume of the second chamber 142 becomes smaller, and the liquid in the second chamber 142 flows toward the first chamber 141 under the action of pressure, the pressure in the first chamber 141 increases and causes the leather cup assembly 11 to deform, so that the volume of the first chamber 141 increases accordingly; and, when the reciprocating part moves downward, the volume of the second chamber 142 increases and the pressure decreases, and the liquid in the first chamber 141 flows toward the second chamber 142 under the action of the leather cup assembly 11, thereby achieving reciprocating flow of liquid between the first chamber 141 and the second chamber 142, producing a damping effect.

[0075] In some embodiments, the leather cup assembly 11 includes a leather cup frame 111 and an elastic leather cup 112. The leather cup frame 111 is connected to the circumferential edge of the elastic leather cup 112. The leather cup frame 111 can be constructed as an annular frame, that is, the leather cup frame 111 can be arranged around the elastic leather cup 112. The leather cup frame 111 is fixedly connected to the flow channel assembly 12, and the first cavity 141 is formed between the elastic leather cup 112 and the flow channel assembly 12. Among them, the leather cup frame 111 can be made of metal material, and the elastic leather cup 112 is made of rubber material, that is, the leather cup frame 111 has a high structural strength, and the elastic leather cup 112 can be deformed as the pressure of the first cavity 141 changes to facilitate the reciprocating flow of the liquid.

[0076] Among them, Figure 1 As shown, the elastic leather cup 112 and the flow channel assembly 12 are relatively distributed in the up and down directions to jointly define a first cavity 141. The pressure in the first cavity 141 can directly act on the lower surface of the elastic leather cup 112. The elastic leather cup 112 elastically deforms upward when the pressure in the first cavity 141 increases, and elastically deforms downward when the pressure in the first cavity 141 decreases, thereby facilitating the reciprocating flow of the liquid.

[0077] At the same time, the elastic leather cup 112 can be connected to the leather cup frame 111 through a vulcanization process, and then when the leather cup frame 111 is connected to the flow channel component 12, good connection reliability can be maintained. Among them, the leather cup frame 111 can be press-fitted with the flow channel component 12 by interference, such as Figure 1 As shown, the upper end portion of the flow channel assembly 12 is pressed onto the bottom of the leather cup frame 111, thereby fixing the two together without providing a separate connecting piece, which helps to reduce the connection cost.

[0078] In some embodiments, the leather cup frame 111 is provided with a liquid injection hole, and the damping liquid can be injected into the hydraulic cavity through the leather cup frame 111 from the liquid injection hole, thereby achieving the function of liquid injection or liquid replenishment.

[0079] Among them, the leather cup skeleton 111 is provided with a liquid injection hole, which can also ensure that the shape of the liquid injection hole is fixed and not easy to deform, so that the liquid injection hole can be selectively blocked in cooperation with the sealing cover, that is, the liquid injection hole can be opened during liquid injection or replenishment, and the liquid injection hole can be blocked during the vibration absorption process of the vibration absorber 100, thereby realizing a reasonable liquid injection effect.

[0080] In some embodiments, the flow channel assembly 12 includes a flow channel main plate 121 and a flow channel cover plate 122. The flow channel main plate 121 is respectively connected to the leather cup assembly 11 and the elastic module 13. The flow channel cover plate 122 is installed on the flow channel main plate 121 and is connected to the flow channel main plate 121 and defines a connecting flow channel 143 with the flow channel main plate 121. The connecting flow channel 143 is connected between the first cavity 141 and the second cavity 142. Therefore, the flow channel assembly 12 is set to realize the molding of the hydraulic cavity.

[0081] Among them, Figure 1 As shown, the flow channel main plate 121 is formed with a flow channel groove which is open downward, and the middle part of the flow channel groove protrudes downward. The flow channel cover plate 122 is connected to the flow channel groove and fits with the middle part of the flow channel groove. The upper part of the flow channel main plate 121 and the elastic leather cup 112 define a second cavity 142, and the top of the flow channel main plate 121 is press-fitted with the leather cup frame 111. At the same time, the flow channel main plate 121, the flow channel cover plate 122 and the elastic module 13 jointly define a first cavity 141. Thus, the first cavity 141 and the second cavity 142 can be connected through the connecting flow channel 143 between the flow channel main plate 121 and the flow channel cover plate 122, so as to achieve reciprocating flow of liquid.

[0082] It should be noted that flow channel holes can be set on the flow channel main board 121 and the flow channel cover plate 122, that is, the first cavity 141 and the connecting flow channel 143 are connected through the flow channel hole provided on the flow channel cover plate 122, and the second cavity 142 and the connecting flow channel 143 are connected through the flow channel hole provided on the flow channel main board 121, so that the reciprocating flow of liquid between the first cavity 141, the connecting flow channel 143 and the second cavity 142 can be realized, and the reasonable design of the liquid flow path is realized, the structure is simple, and the design is convenient.

[0083] In some embodiments, the elastic module 13 includes an internal skeleton 131, an external skeleton 132 and an elastic body 133, and the internal skeleton 131 and the external skeleton 132 are relatively fixed by the elastic body 133. Among them, the internal skeleton 131 and the external skeleton 132 can be made of metal materials to ensure the structural strength of the two, and the elastic body 133 can be fixedly connected to the internal skeleton 131 and the external skeleton 132 by a vulcanization process, so that the internal skeleton 131, the external skeleton 132 and the elastic body 133 are connected as a whole.

[0084] The external skeleton 132 is located at the outer edge of the elastic body 133 and is connected to the hydraulic module, that is, the external skeleton 132 can be configured as a ring, and the external skeleton 132 is arranged around the elastic body 133. Specifically, a skeleton flange 1321 is formed on the outer side of the external skeleton 132, and the skeleton flange 1321 can be used as a limiting flange portion, that is, the skeleton flange 1321 can extend into the limiting installation groove 34 and overlap with the shell flange 331, so as to be limitedly installed with the first shell 31 and the second shell 32 together.

[0085] The internal skeleton 131 is located in the central area of ​​the elastomer 133, and at least part of the internal skeleton 131 and the elastomer 133 are constructed as reciprocating parts, that is, the middle part of the internal skeleton 131 and the elastomer 133 can reciprocate in the up and down directions under the action of the motor structure, and the second cavity 142 is formed on the upper side of the internal skeleton 131 and the elastomer 133. When the middle area of ​​the internal skeleton 131 and the elastomer 133 moves in the up and down directions, the liquid in the second cavity 142 can flow back and forth between the first cavity 141.

[0086] Therefore, when the reciprocating part is driven to perform reciprocating motion by the motor structure, the elastic body 133 and the elastic leather cup 112 can both restore the reciprocating part to the center position, that is, they play a role in pushing the reciprocating part back to the center during the reciprocating motion, which is conducive to achieving rapid reciprocation.

[0087] The invention also provides a control system of the vibration absorber.

[0088] The control system of the vibration absorber according to the embodiment of the present invention comprises a control module and the vibration absorber 100 of any of the above embodiments, wherein the control module comprises a wireless transmitting module, and the wireless transmitting module is used to send a control signal to the wireless receiving module 4. The control system can be mounted on a vibration-absorbing device with a vibration-absorbing demand, and when the vibration-absorbing device has a vibration-absorbing demand, the vibration absorption can be actively controlled by the control module, that is, the wireless transmitting module is controlled by the control module to send a wireless control signal toward the wireless receiving module 4, and after receiving the control signal, the wireless receiving module 4 can control the motor structure to move, thereby causing the vibration absorber 100 to produce a vibration-absorbing effect.

[0089] Therefore, after the vibration absorbing device is equipped with the control system, there is no need to set a connecting harness for electrical connection between the control module and the vibration absorber 100, thereby reducing the setting cost of the connecting harness. The control module and the vibration absorber 100 can be set at relatively far relative positions respectively, thereby reducing the limitation of the installation position of the vibration absorber 100.

[0090] The vibration absorber 100 and the control module may be arranged in a one-to-one correspondence or a one-to-many arrangement, so as to improve the flexibility of the control system arrangement.

[0091] In some embodiments, there are multiple vibration absorbers 100, and the wireless transmission module is used to send a control signal to the wireless transmission module of at least one vibration absorber 100, that is, the control system of the vibration absorber may include a control module and multiple vibration absorbers 100, so that the multiple vibration absorbers 100 can be controlled separately through the same control module. It should be noted that when the device to be vibration-absorbed has a vibration absorption requirement, multiple positions on it can be set for vibration absorption. For example, when the device to be vibration-absorbed is a vehicle, multiple positions on the vehicle need vibration absorption. Therefore, multiple vibration absorbers 100 can be set on the device to be vibration-absorbed, and the multiple vibration absorbers 100 are arranged at intervals on the device to be vibration-absorbed, so as to absorb vibrations at multiple positions respectively, thereby helping to improve the overall vibration absorption effect.

[0092] Among them, using the same control module to control vibration absorption of multiple vibration absorbers 100 can not only reduce the number of controls and reduce the setting cost, but also the control module can flexibly control vibration absorption according to the vibration absorption requirements of the equipment to be vibration absorbed, that is, control multiple vibration absorbers 100 to absorb vibration from different positions at the same time, and can also control a part of the multiple vibration absorbers 100 to perform active vibration absorption operations, thereby improving the flexibility of vibration absorption control.

[0093] In specific settings, if the device to be vibration-absorbed is a vehicle or has a shape similar to that of a vehicle, vibration absorbers 100 may be provided at the front, rear, left, and right positions of the device to be vibration-absorbed, and then flexibly controlled according to actual vibration-absorption requirements to meet a wider range of vibration-absorption requirements.

[0094] The present invention also provides a vehicle.

[0095] The vehicle according to the embodiment of the present invention includes a control system of the shock absorber of any of the above embodiments, that is, through the cooperation of the shock absorber 100 and the control module of the control system, the vibration absorption effect of the vehicle can be achieved, thereby reducing the vibration effect of the vehicle and improving driving comfort.

[0096] Among them, when arranging the control system of the shock absorber on the vehicle, there is no need to set a connecting harness between the control module and the shock absorber 100, and wireless signal transmission can be directly performed, which saves a large number of connecting harnesses, improves safety, and saves the later maintenance costs due to aging of wires, bringing certain cost-effectiveness; in addition, the wireless control method completely decouples the control module and the shock absorber 100 in space, is not restricted by the control module in the vehicle layout space, and is more convenient to arrange.

[0097] In some embodiments, the vehicle also includes a vehicle controller, which includes a control module, that is, the control module of the control system can be integrated into the vehicle controller to actively control multiple shock absorbers 100 through the vehicle controller, thereby reducing the setting of separate control modules, reducing the setting cost, and reducing the setting space occupied by the separate control modules.

[0098] And, the vehicle is equipped with a main vibration system, wherein the vehicle controller is suitable for controlling the wireless transmission module to send a control signal according to the acceleration of the vehicle, specifically, Figure 3 As shown, after the vehicle controller receives the error acceleration sensor signal of the main vibration absorption system, it determines the vibration state of the current main vibration system and calculates and outputs a voltage waveform of a specific frequency and magnitude to the control module of the control system. The wireless transmitting module of the control module then sends a wireless signal to the wireless receiving module 4. After the wireless receiving module 4 receives the control voltage waveform, it drives the motor structure to work to reduce the vibration of the main vibration system and play a vibration absorption role. In this way, the vibration absorption effect of the vehicle can be achieved.

[0099] It should be noted that the control system in the present invention can work based on wifi working in the 5G frequency band to reduce interference in the 2.4G frequency band. In addition, the wireless transmission module can be used as a base station (AP), the vehicle controller is ECU, the SSID of P is a unique identifier preset by the factory, and the authentication password is a random 8-bit character preset by the factory (including uppercase and lowercase letters, numbers, special symbols). The SSID and authentication password are marked on the surface of the wireless transmission module; each wireless receiving module 4 presets the SSID and password of the matching AP.

[0100] And during specific control, the control system is powered on, and the wireless receiving module 4 automatically connects to the AP. The AP determines whether all the wireless receiving modules 4 are successfully connected according to the preset number of connections. If the number does not match, the AP will feedback 0 current to the ECU from the input port corresponding to the unconnected wireless receiving module 4. After the connection is established, the AP sends switch data to each wireless receiving module 4 every 1ms according to the switch instructions of each channel of the ECU. In order to reduce interference, each wireless receiving module 4 counts the switch data within 10ms. If it contains 80% of the same instructions (on or off), the output is set to the corresponding state. In this way, the wireless receiving module 4 can output control with a response time of 10ms to meet the minimum response time of 20ms of the solenoid valve. At the same time, the wireless receiving module 4 determines the actual switch, short circuit, and open circuit status of the motor structure according to the feedback current of the motor structure, and returns it to the AP. The AP determines the motor structure status with the same 10ms anti-interference strategy, and returns the corresponding feedback current to the ECU for fault detection. In this way, active vibration absorption control of multiple vibration absorbers 100 can be achieved.
