Description

Technical Field

[0001] The present invention relates to the technical field of magnetorheological shock absorbers, and particularly to a detection device for a magnetorheological shock absorber. Background Art

[0002] Magnetorheological shock absorbers utilize the magnetorheological effect and, based on the input information from sensors monitoring the movement of the vehicle body and wheels, respond in real time to road conditions and driving environments. Magnetorheological fluid is a suspension containing soft magnetic particles. When the fluid flows through the electromagnetic coil inside the shock absorber piston, the magnetic field of the coil changes its rheological properties and generates fluid resistance, enabling the generation of a rapidly responsive and highly controllable damping force without the need for an electromechanical control valve and with a simple mechanical structure. Existing magnetorheological shock absorbers for new energy motor vehicles include a working cylinder with a sealed tube fixed to its inner wall, and an oil storage layer is formed between the working cylinder and the sealed tube; two symmetrically distributed oil holes are provided at the bottom of the outer wall of the sealed tube. This design achieves an efficient shock absorption effect by increasing the piston return resistance.

[0003] Magnetorheological shock absorbers need to be tested before being put into use. The existing testing mechanisms have a single testing method and cannot accurately detect the shock absorption effects of various states of magnetorheological shock absorbers during use, resulting in a low accuracy of the performance testing of magnetorheological shock absorbers. Summary of the Invention

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a detection device for a magnetorheological shock absorber, which is used to solve the problem that the existing testing mechanisms in the prior art have a single testing method and cannot accurately detect the shock absorption effects of various states of magnetorheological shock absorbers during use.

[0031] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0032] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the illustrations, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and proportion of each component in actual implementation can be arbitrarily changed, and the layout type of its components may also be more complex.

[0033] In the following description, a large number of details are explored to provide a more thorough explanation of the embodiments of the present disclosure. However, it is obvious to those skilled in the art that the embodiments of the present disclosure can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present disclosure difficult to understand.

[0034] Please refer to Figure 1 and Figure 2 , the present invention provides a detection device for a magnetorheological shock absorber, including: a protective box 1, a detection mechanism, a fixing mechanism 4, and a flipping mechanism 6. An accommodation cavity 101 for placing the magnetorheological shock absorber is provided inside the protective box 1. The protective box 1 has a placement opening located at the top of the protective box 1. The magnetorheological shock absorber is placed into the protective box 1 through the placement opening at the top. The flipping mechanism 6 is located inside the accommodation cavity 101, and the flipping mechanism 6 has multiple flipping detection positions at different positions. The detection mechanism is arranged inside the protective box 1 and is arranged on the flipping mechanism 6. The detection mechanism moves synchronously with the flipping mechanism 6. The detection mechanism is used to detect whether the quality of the magnetorheological shock absorber meets the standard. The fixing mechanism 4 is arranged inside the protective box 1 and is arranged on the flipping mechanism 6 (or the fixing mechanism 4 is arranged on the inner wall of the protective box 1, which is not limited here). The fixing mechanism 4 is arranged adjacent to the detection mechanism. The fixing mechanism 4 is within the detection range of the detection mechanism. The fixing mechanism 4 has a fixing state for fixing the magnetorheological shock absorber and a release state for releasing the magnetorheological shock absorber. When the fixing mechanism 4 is in the fixed position, the magnetorheological shock absorber is fixed and limited. When the fixing mechanism 4 is in the release position, the fixing mechanism 4 releases the fixation of the magnetorheological shock absorber, and the magnetorheological shock absorber can be replaced or placed. The flipping mechanism 6 drives the magnetorheological shock absorber to flip into different placement states (vertical state, horizontal state, inclined state, or shaking state, etc.), and the detection mechanism can detect the magnetorheological shock absorber in different states, making the detection results more accurate.

[0035] The cover plate 2 is hinged to the protection box 1, and the cover plate 2 covers the placement opening. A linkage mechanism 5 is further arranged between the protection box 1 and the cover plate 2. The linkage mechanism 5 includes a transmission chain 501, a runner 502 and a reset member 503 (in this embodiment, the reset member 503 is a volute spring). One end of the transmission chain 501 is connected to the cover plate 2, the other end of the transmission chain 501 is fixedly connected to the runner 502, and this end of the transmission chain 501 is wound around the circumferential surface of the runner 502 for multiple turns. The runner 502 is connected to the reset member 503, the runner 502 is connected to the fixing mechanism 4. When the cover plate 2 is opened, the movement of the cover plate 2 drives the transmission chain 501 to move, the transmission chain 501 drives the runner 502 to rotate forward, and the runner 502 drives the fixing mechanism 4 to move, so that the fixing mechanism 4 is in a release state. When the cover plate 2 is closed, the reset member 503 drives the runner 502 to rotate reversely, while resetting the transmission chain 501, it drives the fixing mechanism 4 to close, and the fixing mechanism 4 is in a fixed state. Closing the cover plate 2 initially fixes the magnetorheological shock absorber. The fixing mechanism 4 moves synchronously with the cover plate 2, making it more convenient to use.

[0036] Specifically, in an alternative embodiment of the present invention, two sets of the linkage mechanism 5 are provided, and the two sets of the linkage mechanism 5 are respectively arranged on the opposite side edges of the protection box 1; the two transmission chains 501 are hinged to the side where the cover plate 2 opens and closes. The fixing mechanism 4 includes a preliminary limiting component, and the preliminary limiting component includes a first limiting member 401 and a second limiting member 402. The first limiting member 401 and the second limiting member 402 are relatively hinged and arranged on the opposite inner side surfaces of the protection box 1. The first limiting member 401 is connected to one of the runners 502, and the second limiting member 402 is connected to the other runner 502.

[0037] Specifically, in an alternative embodiment of the present invention, through grooves 102 are arranged on both side walls inside the protection box 1 along the up-down direction for the transmission chain 501 to pass through, and hidden grooves 103 for accommodating the transmission chain 501 are further arranged at the tops of both side walls of the protection box 1. When the cover plate 2 is closed, the transmission chain 501 is placed in the hidden groove 103.

[0038] Specifically, in an alternative embodiment of the present invention, the flipping mechanism 6 includes a mounting plate 601 and a rotating shaft 602. A driving member 603 is provided outside or inside the protective box 1. In this embodiment, the driving member is located outside the protective box 1. The rotating shaft 602 is disposed inside the protective box 1. The mounting plate 601 passes through the side wall of the protective box 1 and is connected to the rotating shaft 602. The output end of the driving member 603 is connected to the rotating shaft 602. The driving member 603 drives the mounting plate 601 to flip through the rotating shaft 602. The driving member 603 is a flipping motor. The flipping motor and the rotating shaft 602 are transmitted by means of a turbine drive, a gear drive, or a chain drive, which is not limited in this embodiment. The flipping motor drives the rotating shaft 602 to rotate. The rotating shaft 602 is fixedly connected to the mounting plate 601. The rotating shaft 602 drives the mounting plate 601 to rotate around the axis of the rotating shaft 602. Thus, when the detection mechanism detects the magnetorheological shock absorber, it can be detected in a vertical state, a horizontal state, and an inclined state, and the detection result is more accurate.

[0039] Please refer to Figure 2 , specifically, in an alternative embodiment of the present invention, the detection mechanism is the execution component 33. A support ring 31, a driving component 32 (in this embodiment, the driving component 32 is driven by a cylinder to drive the execution component 33 to perform a telescopic movement), and a walking component 34 are provided outside the protective box 1. The support ring 31 is disposed outside the protective box 1. The protective box 1 is located at the center of the support ring 31. The walking component 34 is movably disposed on the support ring 31. The walking component 34 can reciprocate back and forth along the circumferential direction of the support ring 31. The driving component 32 is fixedly connected to the walking component 34. The walking component 34 reciprocates around the circumference of the support ring 31 on the support ring 31, driving the driving component 32 to move. The protective box 1 is provided with a first avoidance groove 104 along the flipping direction of the mounting plate 601. The first avoidance groove 104 is used to avoid the driving component 32. The output end of the driving component 32 passes through the first avoidance groove 104 and is disposed inside the protective box 1. When the walking component 34 drives the driving component 32 to move, the output end of the driving component 32 reciprocates in the first avoidance groove 104, avoiding the influence of the body of the protective box 1 on the movement of the driving component 32. The execution component 33 is connected to the output end of the driving component 32. By disposing the support ring 31, the driving component 32, and the walking component 34 outside the protective box 1, it can ensure that the execution component 33 follows the flipping of the mounting plate 601 while ensuring sufficient installation space inside the protective box 1. The walking component 34 maintains synchronous movement with the flipping motor and the rotating shaft 602, so that the rotation amplitude of the rotating shaft 602 is consistent with the walking amplitude of the walking component 34. The driving component 32 drives the execution component 33 to perform a pushing or stretching movement on the magnetorheological shock absorber.

[0040] Please refer toFigure 3 and Figure 4 Specifically, in an alternative embodiment of the present invention, the actuating assembly 33 includes a connecting rod 331, a pushing and pulling member 332, and a telescopic member 333. The pushing and pulling member 332 can be a plate-shaped structure, a columnar structure, a rod-shaped structure, etc., as long as it can implement the structure of this embodiment, and there is no limitation here. In this embodiment, the pushing and pulling member 332 is a rectangular plate structure. One end of the connecting rod 331 is connected to the output end of the driving member 32, and the driving member 32 drives the connecting rod 331 to expand and contract. The other end of the connecting rod 331 is connected to the middle of the pushing and pulling member 332. Connecting holes 334 and clamping portions 335 are provided at both the first end and the second end in the length direction of the pushing and pulling member 332. The clamping portions 335 are hinged to the pushing and pulling member 332. One ends of two connecting bands are respectively connected to the ends of the two clamping portions 335 away from the pushing and pulling member 332. The connecting band connected to the clamping portion 335 at the first end passes through the connecting hole 334 at the second end and is connected to the output end of the telescopic member 333. The connecting band connected to the clamping portion 335 at the second end passes through the connecting hole 334 at the first end and is connected to the output end of the telescopic member 333. The output end of the telescopic member 333 faces the pushing and pulling member 332, or the output end of the telescopic member 333 faces away from the pushing and pulling member 332. Among them, return springs are provided on the connecting rod 331 for both of the clamping portions 335. When the telescopic member 333 contracts, it drives the two connecting bands to move towards the telescopic member 333, thereby driving the two clamping portions 335 to move towards each other to clamp the magnetorheological shock absorber, facilitating the driving member 32 to drive the magnetorheological shock absorber to perform a stretching motion for detection. When the telescopic member 333 extends towards the pushing and pulling member 332, both of the clamping portions 335 reduce the inclination amplitude with respect to the pushing and pulling member 332 under the action of the return springs, and under the action of the return springs, the angle between the clamping portion 335 and the pushing and pulling member 332 remains obtuse.

[0041] Specifically, in an alternative embodiment of the present invention, a second avoidance groove 336 for accommodating the connecting band is provided on the pushing and pulling member 332, and the connecting band is hidden in the second avoidance groove 336 to avoid the situation where the connecting band is pulled by other mechanisms.

The outer surface and the inner surface of the support ring 31 are both provided with a slide groove 311 along the circumferential direction. The slide grooves 311 on the outer surface and the inner surface are arranged opposite to each other, and both sides of the two slide grooves 311 are provided with limit plates to limit the walking assembly 34 to prevent the walking assembly 34 from disengaging from the slide groove 311. The first walking portion 342 is movably arranged in the slide groove on the outer surface of the support ring 31, and the second walking portion 343 is movably arranged inside the slide groove 311 on the inner surface of the support ring 31. The first walking portion 342 and the second walking portion 343 are both fixedly connected to the mounting frame 341. The driving component 32 is fixedly connected to the mounting frame 341. The first walking portion 342 and the second walking portion 343 are connected by a belt The movable mounting frame 341 moves, thereby driving the driving component 32 to move, and further realizing the synchronous movement of the driving component 32 and the mounting plate 601. The first walking part 342 and the second walking part 343 are both provided with a locking resistance part 344. The resistance part 344 is used to abut against the bottom of the slide groove 311 after the first walking part 342 and the second walking part 343 reach the specified position, so as to lock the first walking part 342 and the second walking part 343 in the specified position to prevent them from sliding and causing incorrect positions. When the first walking part 342 and the second walking part 343 need to move, the resistance part 344 is separated from the slide groove 311. In this embodiment, the resistance part 344 can realize telescopic movement by turbine drive, cylinder drive or gear transmission. The first walking part 342 and the second walking part 343 are both composed of a connecting plate and a walking wheel.

[0043] Specifically, in an optional embodiment of the present invention, a stopper for limiting position is further provided on the mounting plate 601. When the mounting plate 601 needs to be flipped, the stopper performs a contraction movement.

The fixing member 404 and the positioning plate 405 are arranged opposite to each other, and a receiving space for placing the magnetorheological shock absorber is formed between the fixing member 404 and the positioning plate 405. The fixing cylinder 403 drives the fixing member 404 to move, thereby adjusting the size of the receiving space to fix or release the magnetorheological shock absorber;

[0045] Among them, the fixing member 404 includes a first fixing surface and a second fixing surface. The fixing member 404 includes a vertical plate and an inclined plate.
