[0040] The following specifically describes the shock absorber 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0041] As Figure 1 shown, the shock absorber 100 according to an embodiment of the present invention includes a working cylinder 10, a piston rod 20, and a wire harness assembly 50.

[0042] Specifically, a working cavity 11 is provided inside the working cylinder 10, and the working cylinder 10 is a permanent magnet material cylinder. One end of the piston rod 20 extends into the working cavity 11, and the piston rod 20 is movable relative to the working cylinder 10, and the piston rod 20 forms a hollow structure. The wire harness assembly 50 is arranged inside the hollow structure. When the shock absorber 100 works, the wire harness assembly 50 can cut the magnetic field lines generated by the working cylinder 10 and generate an induced current.

[0043] In other words, referring to Figure 1 , the shock absorber 100 according to an embodiment of the present invention mainly consists of a working cylinder 10, a piston rod 20, and a wire harness assembly 50. Among them, a working cavity 11 is provided inside the working cylinder 10, and the working cylinder 10 can be made of permanent magnet material. The working cylinder 10 made of permanent magnet material can generate magnetic induction lines, and the piston rod 20 and the solenoid valve 30 are built-in. As the main working area of the shock absorber 100, there is no need to additionally arrange a magnetic structure inside the structure of the shock absorber 100, reducing the occupied space of the shock absorber 100, facilitating the arrangement of other structures inside the shock absorber 100, and making the structure of the shock absorber 100 simpler.

[0044] As Figure 1 shown, one end of the piston rod 20 can extend into the working cavity 11, and the piston rod 20 is movable relative to the working cylinder 10. The piston rod 20 can be set as a hollow structure to facilitate the arrangement of the wire harness assembly 50 inside the piston rod 20, providing a layout space for the wire harness assembly 50. There is no need to arrange the wire harness assembly 50 outside the working cylinder 10 or on the outer wall surface of other structures, preventing the wire harness assembly 50 from being exposed outside and interfering with other structural components, and improving the working safety of the shock absorber 100. The wire harness assembly 50 is arranged inside the hollow structure of the piston rod 20. When the shock absorber 100 works, the wire harness assembly 50 can cut the magnetic field lines generated by the working cylinder 10 and generate an induced current.

[0045] Thus, for the shock absorber 100 according to the embodiment of the present invention, the working cylinder 10 is made of a permanent magnetic material, eliminating the need for additional mechanisms such as magnetic poles. At the same time, the piston rod 20 is configured as a hollow structure, and the wire harness assembly 50 is disposed within the hollow structure. By the swinging of the wire harness assembly 50 to cut the magnetic induction lines, an induced current is generated, achieving the effective recovery and utilization of energy without adding extra structural components and volume to the shock absorber 100. The generation of the induced current can effectively resist the reaction force of the shock absorber 100 from bouncing, can replace part of the function of the oil in the shock absorber 100, reduce the amount of oil in the shock absorber 100, ensure the reliability and safety of the operation of the shock absorber 100, and reduce the overall volume design of the shock absorber 100.

[0046] According to an embodiment of the present invention, the shock absorber 100 further includes a solenoid valve 30 and an energy recovery device 40. Among them, the solenoid valve 30 is disposed in the working chamber 11, and one end of the piston rod 20 extending into the working chamber 11 is connected to the solenoid valve 30. The energy recovery device 40 is disposed at one end of the piston rod 20 far from the solenoid valve 30. The wire harness assembly 50 is disposed within the hollow structure, and both ends of the wire harness assembly 50 are respectively connected to the energy recovery device 40 and the solenoid valve 30; when the shock absorber 100 is operating, the wire harness assembly 50 can cut the magnetic field lines generated by the working cylinder 10 and generate an induced current to supply to the solenoid valve 30 and / or the energy recovery device 40.

[0047] That is to say, as Figure 1 shown, the shock absorber 100 further includes a solenoid valve 30 and an energy recovery device 40. Among them, the solenoid valve 30 is installed in the working chamber 11, and one end of the piston rod 20 extending into the working chamber 11 can be connected to the solenoid valve 30. The solenoid valve 30 can control the opening degree change through the current change, thereby realizing the damping adjustment of the shock absorber 100. The energy recovery device 40 is installed at one end of the piston rod 20 far from the solenoid valve 30. The energy recovery device 40 can rectify, filter, and regulate the generated induced current. Finally, the direct current with a flat waveform and stable voltage is input to the battery or other low-voltage loads through the vehicle wiring harness. The wire harness assembly 50 is arranged within the hollow structure of the piston rod 20, and both ends of the wire harness assembly 50 are respectively connected to the energy recovery device 40 and the solenoid valve 30.

[0048] In the present invention, by replacing the working cylinder 10 in the shock absorber 100 with a permanent magnetic material and configuring the piston rod 20 as a hollow structure, a wire harness circuit for generating current is integrated therein. When the shock absorber 100 is operating and bouncing up and down, the wire harness assembly 50 can cut the magnetic induction lines, thereby generating an induced current, and the faster the shock absorber 100 bounces up and down, the greater the generated current. The generated current can be used for the self-control of the solenoid valve 30 of the shock absorber 100 on the one hand. On the other hand, it is output to charge the battery, increasing the battery's endurance ability, realizing the conversion of part of the kinetic energy into electrical energy instead of all being converted into heat energy.

[0049] The shock absorber 100 of the present invention is a new type of electronically controlled adjustable damping shock absorber 100 with energy recovery. The shock absorber 100 of the present invention is based on a shock absorber 100 with electronically controlled adjustable damping of an in-built solenoid valve 30. Only the material of the working cylinder 10, the wiring harness structure are changed, and an energy recovery device 40 is added externally. No additional internal structure of the shock absorber 100 is added to achieve energy recovery, and the volume of the shock absorber 100 does not need to be increased. When an induced current is generated in the wiring harness assembly 50, a reaction force that prevents the shock absorber 100 from bouncing will be generated, which can replace part of the function of the oil in the shock absorber 100, reduce the amount of oil in the shock absorber 100, thereby reducing the volume of the shock absorber 100, lowering the working temperature of the shock absorber 100, and improving the working reliability and safety of the shock absorber 100.

[0050] Of course, for those skilled in the art, the principle of generating an induced current by cutting magnetic induction lines and the specific working principle of the shock absorber 100 can be understood and implemented, and will not be elaborated in detail in the present invention.

[0051] Thus, for the shock absorber 100 according to an embodiment of the present invention, the working cylinder 10 is made of a permanent magnet material, and no additional mechanisms such as magnetic poles need to be provided. At the same time, the piston rod 20 is set to be a hollow structure, and the wiring harness assembly 50 is arranged in the hollow structure. By swinging the wiring harness assembly 50 to cut the magnetic induction lines, an induced current is generated and supplied to the solenoid valve 30 or the energy recovery device 40. Without adding additional structural components and volume to the shock absorber 100, effective recovery and utilization of energy are achieved. The generation of the induced current can effectively prevent the reaction force of the shock absorber 100 from bouncing, which can replace part of the function of the oil in the shock absorber 100, reduce the amount of oil in the shock absorber 100, ensure the working reliability and safety of the shock absorber 100, and reduce the overall volume design of the shock absorber 100.

[0052] According to an embodiment of the present invention, the wiring harness assembly 50 includes a spiral wiring harness 51 and a plurality of straight wiring harnesses 52.

[0053] Specifically, the spiral wiring harness 51 is arranged in the hollow structure of the piston rod 20. The first end of the spiral wiring harness 51 is connected to the energy recovery device 40, and the second end is connected to the solenoid valve 30. The plurality of straight wiring harnesses 52 are spaced apart and arranged in the hollow structure. The first end of each straight wiring harness 52 is connected to the energy recovery device 40, and the second end of at least one straight wiring harness 52 is connected to the solenoid valve 30. The second end of the spiral wiring harness 51 is connected to the second end of at least one straight wiring harness 52 to form at least one current loop.

[0054] That is to say, as Figure 1 and Figure 2As shown, the wire harness assembly 50 mainly consists of a spiral wire harness 51 and a plurality of straight wire harnesses 52. Among them, the spiral wire harness 51 is spiral and is arranged in the hollow structure of the piston rod 20. The first end of the spiral wire harness 51 is connected to the energy recovery device 40, and the second end is connected to the solenoid valve 30. The first end and the second end of the spiral wire harness 51 are two free ends of the spiral wire harness 51. The plurality of straight wire harnesses 52 are arranged at intervals in the hollow structure. The first end of each straight wire harness 52 is connected to the energy recovery device 40, and the second end of at least one straight wire harness 52 can be connected to the solenoid valve 30. The second end of the spiral wire harness 51 and the second end of at least one straight wire harness 52 can be connected to form at least one current loop to supply the generated induced current to the energy recovery device 40 or the solenoid valve 30.

[0055] The first end and the second end of each straight wire harness 52 are respectively the two ends in the length direction of the straight wire harness 52. By arranging the spiral wire harness 51 and the plurality of straight wire harnesses 52 in the hollow structure of the piston rod 20, a layout space is provided for the wire harness assembly 50, eliminating the need to arrange the wire harness assembly 50 outside the working cylinder 10 or on the outer wall surfaces of other structures, preventing the wire harness assembly 50 from being exposed externally and interfering with other structural components, thus enhancing the working safety of the shock absorber 100.

[0056] According to an embodiment of the present invention, the plurality of straight wire harnesses 52 are respectively a first wire harness 521, a second wire harness 522, and a third wire harness 523. One ends of the first wire harness 521, the second wire harness 522, and the third wire harness 523 facing the energy recovery device 40 are respectively connected to the energy recovery device 40. One end of any one of the first wire harness 521, the second wire harness 522, and the third wire harness 523 facing the solenoid valve 30 can be connected to the second end of the spiral wire harness 51, and any two of the first wire harness 521, the second wire harness 522, and the third wire harness 523 can be connected.

[0057] In other words, as Figure 1 and Figure 2 shown, the plurality of straight wire harnesses 52 can be respectively a first wire harness 521, a second wire harness 522, and a third wire harness 523. Among them, one ends of the first wire harness 521, the second wire harness 522, and the third wire harness 523 facing the energy recovery device 40 can be respectively connected to the energy recovery device 40. One end of any one of the first wire harness 521, the second wire harness 522, and the third wire harness 523 facing the solenoid valve 30 can be connected to the second end of the spiral wire harness 51, and any two of the first wire harness 521, the second wire harness 522, and the third wire harness 523 can be connected, so as to supply the generated induced current to the energy recovery device 40 and / or the solenoid valve 30.

[0058] In the shock absorber 100 of the present invention, the upper end of the spiral wire harness 51 is connected to the energy recovery device 40, and the lower end can be connected to the first wire harness 521 and the third wire harness 523. On the one hand, the opening degree of the solenoid valve 30 can be controlled by the induced current generated by the up and down movement of the shock absorber 100. On the other hand, the induced current can be supplied to the battery or other low-voltage loads through the energy recovery device 40, so as to achieve the effect of energy recovery, improve the endurance of the whole vehicle, and further solve the user's power anxiety.

[0059] The solenoid valve 30 adopted by the shock absorber 100 of the present invention can be a proportional control valve, that is, the greater the current, the smaller the opening degree generated by the solenoid valve 30, and the greater the damping generated at the same time. The upper end of the first wire harness 521 is connected to the energy recovery device 40, and the lower end is directly connected to the spiral wire harness 51 to form a wire harness loop and complete the closure of the wire harness loop. And it forms an energy recovery system with the spiral wire harness 51. The upper end of the second wire harness 522 is connected to the energy recovery device 40, and the lower end can be connected to the third wire harness 523 to control the solenoid valve 30 through the vehicle current signal. The upper end of the third wire harness 523 is connected to the energy recovery device 40, and the lower end is connected to the spiral wire harness 51 through the solenoid valve 30, which is used to form a wire harness loop, complete the closure of the wire harness loop, and form a self-control system of the solenoid valve 30 with the spiral wire harness 51. The energy recovery device 40 can rectify, filter, and stabilize the generated induced current, and finally input the direct current with a flat waveform and stable voltage to the battery or other low-voltage loads through the vehicle wire harness.

[0060] The novel electronically controlled adjustable damping shock absorber 100 capable of energy recovery shown in the present invention is based on the electronically controlled adjustable damping shock absorber 100 with an internal solenoid valve 30. The material of the working cylinder 10 is replaced with a permanent magnet material. The piston rod 20 of the novel electronically controlled adjustable damping shock absorber 100 is of a hollow structure, and the wire harness is located therein. A section of the wire harness is spiral. Replacing the material of the working cylinder 10 with a permanent magnet material can enable the wire harness to cut the magnetic induction line when the shock absorber 100 moves up and down, and the magnetic flux in the wire harness changes, thereby generating an induced current. Moreover, the faster the shock absorber 100 moves up and down, the greater the generated current. The generated current can be used for the self-control of the solenoid valve 30 of the shock absorber 100 on the one hand, and output to charge the battery on the other hand, increasing the endurance of the battery, and realizing the conversion of part of the kinetic energy into electrical energy instead of all being converted into heat energy.

[0061] According to an embodiment of the present invention, the second end of the spiral wire harness 51 is connected to the end of the first wire harness 521 facing the solenoid valve 30, and the ends of the second wire harness 522 and the third wire harness 523 facing the solenoid valve 30 are connected to each other to output the induced current generated by the wire harness assembly 50 to the energy recovery device 40.

[0062] In other words, the second end of the spiral wire harness 51 can be connected to one end of the first wire harness 521 facing the solenoid valve 30. And one end of the second wire harness 522 and the third wire harness 523 facing the solenoid valve 30 can be connected to output the induced current generated by the wire harness assembly 50 to the energy recovery device 40, forming the first working mode of the shock absorber 100, as Figure 3 shown, in the first working mode, the generated induced current can be completely output to the energy recovery device 40. The damping control of the shock absorber 100 can be input to the solenoid valve 30 by the vehicle control unit. At this time, the lower end of the spiral wire harness 51 is connected to the lower end of the first wire harness 521, and the lower end of the second wire harness 522 is connected to the lower end of the third wire harness 523, and the rest of the wire harnesses are disconnected.

[0063] When the shock absorber 100 is in the compression condition, the working cylinder 10 moves upward, the piston rod 20 does not move, and the magnetic flux of the wire harness at the upper end of the piston rod 20 increases. The current direction generated by the spiral wire harness 51 of the shock absorber 100 is from the upper end to the lower end, and flows through the first wire harness 521 to the energy recovery device 40. When the shock absorber 100 is in the rebound condition, the working cylinder 10 moves downward, the piston rod 20 does not move, and the magnetic flux of the wire harness at the upper end of the piston rod 20 decreases. The current direction generated by the spiral wire harness 51 of the shock absorber 100 is from the upper end to the lower end, and the current directly flows to the energy recovery device 40. The current signal of the vehicle control unit controls the opening degree of the solenoid valve 30 through the energy recovery device 40 and the second wire harness 522 and the third wire harness 523, so as to control the damping of the shock absorber 100. The first mode can be applied to the medium and high frequency vibration state of the shock absorber 100, and the user hopes to control the damping state of the shock absorber 100 through the vehicle signal to match better comfort and handling performance.

[0064] According to an embodiment of the present invention, the second end of the spiral wire harness 51 is connected to one end of the first wire harness 521 facing the solenoid valve 30, and the second end of the spiral wire harness 51 is also connected to one end of the third wire harness 523 facing the solenoid valve 30, so that a part of the induced current generated by the wire harness assembly 50 is used for the self-control of the solenoid valve 30, and the other part is output to the energy recovery device 40.

[0065] That is to say, the second end of the spiral wire harness 51 can be connected to one end of the first wire harness 521 facing the solenoid valve 30, and the second end of the spiral wire harness 51 can also be connected to one end of the third wire harness 523 facing the solenoid valve 30, which is convenient for using a part of the induced current generated by the wire harness assembly 50 for the self-control of the solenoid valve 30, and the other part is output to the energy recovery device 40, forming the second working mode of the shock absorber 100.

[0066] As Figure 4As shown, in the second working mode of the shock absorber 100, a part of the induced current generated by the shock absorber 100 is used for the self-control of the solenoid valve 30 in the shock absorber 100, and the other part is output to the energy recovery device 40. At this time, the lower end of the spiral wire harness 51 is connected to the lower end of the third wire harness 523. At the same time, the lower end of the spiral wire harness 51 is also connected to the lower end of the first wire harness 521, and the rest of the wire harnesses are disconnected. A part of the induced current generated in the compression condition flows to the first wire harness 521 for energy recovery, and a part flows to the lower end of the third wire harness 523 to control the opening degree of the solenoid valve 30, thereby controlling the damping of the shock absorber 100.

[0067] A part of the induced current generated in the rebound condition directly flows to the energy recovery device 40, and a part flows to the upper end of the third wire harness 523. The current controls the opening degree of the solenoid valve 30 by flowing through the third wire harness 523, thereby controlling the damping of the shock absorber 100. The second working mode is applicable to the state of high-frequency vibration in the shock absorber 100, and the user hopes that the cyclic feedback of the shock absorber 100 controls the opening degree of the solenoid valve 30 of the shock absorber 100 and the damping of the shock absorber 100.

[0068] According to an embodiment of the present invention, the second end of the spiral wire harness 51 is connected to one end of the third wire harness 523 facing the solenoid valve 30 to use the induced current generated by the wire harness assembly 50 for the self-control of the solenoid valve 30.

[0069] In other words, the second end of the spiral wire harness 51 can be connected to one end of the third wire harness 523 facing the solenoid valve 30, and the induced current generated by the wire harness assembly 50 is used for the self-control of the solenoid valve 30, forming the third working mode of the shock absorber 100. As Figure 5 shown, in the third working mode of the shock absorber 100, the generated current can be completely used for the self-control of the solenoid valve 30 in the shock absorber 100. At this time, the lower end of the spiral wire harness 51 is connected to the lower end of the third wire harness 523, and the rest of the wire harnesses are disconnected. The third working mode is applicable to the working condition of low-frequency vibration of the shock absorber 100. At this time, the moving speed of the shock absorber 100 is low, the generated current is small, and the opening degree of the solenoid valve 30 is large, so that the shock absorber 100 is in a state of small damping. At the same time, when the wire harness generates current, the reaction force that prevents the shock absorber 100 from bouncing is small, and the whole vehicle is in a relatively comfortable state.

[0070] According to an embodiment of the present invention, the shock absorber 100 further includes a control switch, which can be arranged in the working cylinder 10. The spiral wire harness 51, the first wire harness 521, the second wire harness 522 and the third wire harness 523 can be respectively connected to the control switch. By means of the control switch, the connection or disconnection between the spiral wire harness 51, the first wire harness 521, the second wire harness 522 and the third wire harness 523 can be controlled, so as to realize the free switching of the shock absorber 100 among the first working mode, the second working mode and the third working mode, and meet the working requirements of the shock absorber 100 under different working conditions.

[0071] According to an embodiment of the present invention, as Figure 1 shown, the shock absorber 100 further includes an oil storage cylinder 61, a guide sleeve 62 and a bottom valve 63. Among them, an oil storage cavity 611 is arranged in the oil storage cylinder 61, the working cylinder 10 is arranged in the oil storage cavity 611, and the working cylinder 10 is movable relative to the oil storage cylinder 61; the oil storage cylinder is mainly used for storing the redundant oil liquid under the compression condition and compensating the oil liquid under the recovery condition. The guide sleeve 62 is arranged at one end of the working cylinder 10 facing the energy recovery device 40, and the guide sleeve 62 is movable in the oil storage cylinder 61 to provide a guiding effect for the movement of the working cylinder 10 and the piston rod 20. The bottom valve 63 is arranged at one end of the working cylinder 10 far from the guide sleeve 62. The bottom valve 63 is mainly used to connect the working cylinder 10 and the oil storage cylinder and provide damping.

[0072] According to an embodiment of the present invention, referring to Figure 1 , the shock absorber 100 further includes a sealing retaining ring 64 and a lifting ring 65. Among them, the sealing retaining ring 64 is installed at one end of the oil storage cylinder 61 facing the energy recovery device 40 to prevent the shock absorber 100 from leaking oil. The lifting ring 65 is arranged at one end of the oil storage cylinder 61 far from the sealing retaining ring 64, and the lifting ring 65 is mainly used to connect the steering knuckle.

[0073] In summary, the shock absorber 100 of the present invention can achieve energy recovery and damping adjustment by replacing the material of the working cylinder 10 with a permanent magnetic material, setting the piston rod 20 as a hollow structure, and setting the wiring harness assembly 50 in the hollow structure. Through a section of a spiral-shaped wiring harness (spiral wiring harness 51), when the shock absorber 100 jumps up and down, the wiring harness assembly 50 can cut the magnetic flux lines, and the magnetic flux in the wiring harness assembly 50 changes, thereby generating an induced current, and the faster the shock absorber 100 jumps up and down, the greater the current generated. The generated current can be used for the self-control of the electromagnetic valve 30 of the shock absorber 100 on the one hand, and on the other hand, it can be recovered through the energy recovery device 40. The present invention realizes effective energy recovery and utilization without adding additional structural parts and volume to the shock absorber 100. The generation of induced current can effectively prevent the reaction force of the shock absorber 100 from bouncing, and can replace part of the oil effect of the shock absorber 100, reduce the amount of oil in the shock absorber 100, ensure the reliability and safety of the shock absorber 100, and reduce the overall volume design of the shock absorber 100.

[0074] Of course, for those skilled in the art, other structures and working principles of the shock absorber 100 are understandable and achievable, and will not be described in detail in the present invention.

[0075] According to the second aspect of the embodiment of the present invention, a vehicle is provided, comprising the shock absorber 100 in the above embodiment. Since the shock absorber 100 according to the embodiment of the present invention has the above technical effects, the vehicle according to the embodiment of the present invention should also have the corresponding technical effects, that is, the vehicle of the present invention can achieve energy recovery and damping adjustment by adopting the shock absorber 100, and at the same time, can achieve effective energy recovery and utilization without increasing the additional structural parts and volume of the shock absorber 100. The generation of induced current can effectively prevent the reaction force of the shock absorber 100 from bouncing, and can replace part of the oil effect of the shock absorber 100, reduce the amount of oil in the shock absorber 100, ensure the reliability and safety of the shock absorber 100, and reduce the overall volume design of the shock absorber 100. At the same time, it can be used for the self-control of the solenoid valve 30 of the shock absorber 100, and on the other hand, it can be output to charge the battery, increase the endurance of the vehicle, and realize the conversion of part of the kinetic energy into electrical energy instead of all into heat energy.
