[0039] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.
[0040] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0041] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0042] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0043] The utility model discloses a magnetic shock absorber, referring to Figure 1 and Figure 3 As shown, the magnetic shock absorber of this embodiment includes a fixed cylinder 100, a movable cylinder 300 and a guide cylinder 500. One end of the fixed cylinder 100 is used to be connected to the front wheel of the electric two-wheeled vehicle and is provided with a first magnetic member 200. One end of the movable cylinder 300 is connected to the frame of the electric two-wheeled vehicle, and the other end is provided with a second magnetic member 400, which extends into the movable cylinder 300. The guide cylinder 500 is fixed in the fixed cylinder 100 and penetrates the second magnetic member 400. The guide cylinder 500 is used to guide the movable cylinder 300. The repulsive force of the second magnetic member 400 on the first magnetic member 200 can drive the movable cylinder 300 to slide in a direction away from the first magnetic member 200. It is understandable that, since the fixed cylinder 100 is connected to the front wheel of the electric two-wheeled vehicle, when the electric two-wheeled vehicle encounters bumps or external forces during driving, the movable cylinder 300 moves downward, and one end of the fixed cylinder 100 is fixed to the front wheel, and the fixed cylinder 100 remains stationary. When the movable cylinder 300 moves downward, the second magnetic member 400 moves toward the direction close to the first magnetic member 200. Due to the principle of repulsion of the same magnetic poles, the movable cylinder 300 is subjected to an upward reaction force, so that the movable cylinder 300 can be reset and restored to the starting position, thereby achieving a shock-absorbing effect. And as the distance between the first magnetic member 200 and the second magnetic member 400 approaches, the reaction force brought about increases exponentially, so that no matter how bumpy the road surface is, it can bring about a good shock-absorbing effect. In addition, the additional guide cylinder 500 can guide the movement direction of the movable cylinder 300 to prevent the movable cylinder 300 from being skewed.
[0044] Optionally, a fixing hole is provided on the fixing cylinder 100, and the fixing cylinder 100 is fixed to the wheel by screws passing through the fixing hole, thereby ensuring that the fixing cylinder 100 can remain stationary relative to the wheel during actual working.
[0045] Optionally, the fixed cylinder 100 is an aluminum cylinder, the movable cylinder 300 is a steel cylinder, and the guide cylinder 500 is a stainless steel cylinder. The fixed cylinder 100 is an aluminum cylinder, so that the fixed cylinder 100 is lighter, which is beneficial to reducing the mass of the magnetic shock absorber. The movable cylinder 300 is a steel cylinder, which can improve the strength and avoid the bending of the movable cylinder 300 to cause deformation of the frame. The guide cylinder 500 is a stainless steel cylinder, which avoids the phenomenon that the first magnetic part 200 and the second magnetic part 400 adsorb the guide cylinder 500, ensuring the guiding function of the guide cylinder 500. In other embodiments of the utility model, the fixed cylinder 100, the movable cylinder 300 and the guide cylinder 500 can all be selected according to actual needs. The material is not limited to the above-mentioned limitation.
[0046] refer to Figure 2-Figure 3 As shown, a sliding cavity 110 is provided in the fixed cylinder 100, and the sliding cavity 110 has an open end, and the movable cylinder 300 is inserted into the sliding cavity 110 from the open end, and the magnetic shock absorber further comprises a sealing cover 600, which is sleeved on the movable cylinder 300 and inserted into the open end of the sliding cavity 110 to seal the open end of the sliding cavity 110. It can be understood that, when one end of the movable cylinder 300 is inserted into the open end, the movable cylinder 300 is always in the sliding cavity 110 during the actual working process, and the sliding cavity 110 provides a movement space for the movable cylinder 300, limits the movement direction of the movable cylinder 300, and avoids the movable cylinder 300 from being skewed during the actual working process.
[0047] In addition, in the actual assembly process, the sealing cover 600 is first sleeved on the movable cylinder 300, and then one end of the movable cylinder 300 is inserted into the sliding cavity 110, and finally the sealing cover 600 is inserted into the open end of the sliding cavity 110. In this way, the sealing of the sliding cavity 110 is achieved, so that the first magnetic member 200 and the second magnetic member 400 are installed in a relatively closed environment, and external moisture and dust are prevented from entering the sliding cavity 110. On the one hand, the cleanliness of the first magnetic member 200 and the second magnetic member 400 is ensured, and on the other hand, the abnormal friction between the movable cylinder 300 and the inner wall of the sliding cavity 110 caused by external pollutants is avoided, which is conducive to extending the service life of the entire magnetic shock absorber.
[0048] refer to Figure 4 and Figure 5 As shown, the fixed cylinder 100 forms a sealing ring 130 with a larger diameter at the open end of the sliding cavity 110, and the inner peripheral wall of the sealing ring 130 has a clamping groove. The clamping groove is used to clamp the sealing cover 600. In this way, the sealing cover 600 can be prevented from slipping out of the fixed cylinder 100, ensuring that the sliding cavity 110 is stably sealed by the sealing cover 600.
[0049] refer to Figure 5 As shown, a first limiting hole 120 is formed at one end of the sliding cavity 110 away from the movable cylinder 300, referring to Figure 10-11As shown, the first magnetic member 200 has a first plug-in portion 210 and a first stop surface 220 arranged around the first plug-in portion 210, the first plug-in portion 210 is inserted into the first limiting hole 120, and the first stop surface 220 abuts against the end surface of the sliding cavity 110 away from the movable cylinder 300. It can be understood that in the actual installation process, after the first magnetic member 200 is placed in the movable cylinder 300, the movable cylinder 300 is erected, and the first magnetic member 200 moves downward under the action of gravity, the first plug-in portion 210 can be plugged into the first limiting hole 120, and the first stop surface 220 abuts against the end surface of the sliding cavity 110 away from the movable cylinder 300. The stability of the first magnetic component 200 in the fixed tube 100 can be achieved through the cooperation with the first limiting hole 120 and the first plug-in portion 210. In the actual working process, under the action of the repulsive force, the first stop surface 220 can be stably pressed on the end surface of the sliding cavity 110, further ensuring the stability of the first magnetic component 200 in the fixed tube 100.
[0050] In order to further improve the installation stability of the first magnetic member 200, a first locking screw is provided on the fixing cylinder 100, and the first locking screw extends into the sliding cavity 110 along the radial direction of the fixing cylinder 100 and is connected to the first magnetic member 200. Of course, in an alternative embodiment, the first magnetic member 200 can also be directly bonded in the fixing cylinder 100.
[0051] refer to Figure 10-11 As shown, the first magnetic member 200 has a plug hole 230, and the plug hole 230 has a first stop step. Figure 6 and Figure 7 As shown, the end of the guide cylinder 500 away from the movable cylinder 300 has an insertion portion 510, the insertion portion 510 is inserted into the plug hole 230, and the end surface of the insertion portion 510 abuts against the first stop step. It can be understood that, since the first magnetic member 200 can be fixed in the fixed cylinder 100 through the first limiting hole 120 and the cooperation with the first plug-in portion 210, and the guide cylinder 500 can be connected with the first magnetic member 200 through the cooperation of the insertion portion 510 and the plug hole 230, it is ensured that the guide cylinder 500 can be stably maintained inside the fixed cylinder 100, thereby ensuring the guiding effect of the guide cylinder 500 on the movable cylinder 300.
[0052] In order to further improve the stability of the guide cylinder 500, a second locking screw is provided on the fixed cylinder 100, and the first locking screw extends into the sliding cavity 110 along the radial direction of the fixed cylinder 100, passes through the second magnetic member 400 and is connected to the guide cylinder 500. Thus, the fixed cylinder 100, the first magnetic member 200 and the guide cylinder 500 are connected together by the second locking screw, ensuring the connection stability of the first magnetic member 200 and the guide cylinder 500. Of course, in an alternative embodiment, the outer peripheral wall of the insertion portion 510 is bonded to the inner side wall of the plug hole 230.
[0053] refer to Figure 6 and Figure 7 As shown, the end of the guide cylinder 500 facing the movable cylinder 300 has an anti-slip convex ring 520, and the second magnetic member 400 is sleeved on the guide cylinder 500 and is located on the side of the anti-slip convex ring 520 facing the first magnetic member 200. It can be understood that the second magnetic member 400 is sleeved on the guide cylinder 500 and is located on the side of the anti-slip convex ring 520 facing the first magnetic member 200. When the second magnetic member 400 moves under the action of the repulsive force, it will move in the direction close to the anti-slip convex ring 520. The presence of the anti-slip convex ring 520 can prevent the second magnetic member 400 from slipping off from the guide cylinder 500 under the action of the repulsive force.
[0054] Further, refer to Figure 2 and Figure 3 As shown, the guide cylinder 500 is also sleeved with a buffer elastic member 700, one end of the buffer elastic member 700 is stopped at the anti-dropping convex ring 520, and the other end is stopped at the second magnetic member 400. It can be understood that the existence of the buffer elastic member 700 can buffer the movement of the second magnetic member 400, and prevent the second magnetic member 400 from directly hitting the anti-dropping convex ring 520 under the action of repulsive force. Optionally, the buffer elastic member 700 is a spring. Of course, in other embodiments of the utility model, the buffer elastic member 700 can also select an elastic structure such as an elastic gasket according to actual needs.
[0055] refer to Figure 3 , Figure 8 and Fig. 9 As shown, the end of the movable cylinder 300 inserted into the fixed cylinder 100 has a second limiting hole 310, and the diameter of the second limiting hole 310 is smaller than the inner diameter of the movable cylinder 300. Fig.12 and Fig.13As shown, one end of the second magnetic member 400 has a second plug-in portion 410, the second magnetic member 400 is installed in the movable cylinder 300, and the second plug-in portion 410 passes through the movable cylinder 300 from the second limiting hole 310. It can be understood that, since the diameter of the second limiting hole 310 is smaller than the inner diameter of the movable cylinder 300, in the actual movement process, when the second magnetic member 400 moves under the action of the repulsive force, due to the limiting effect of the end of the movable cylinder 300, the phenomenon of the second magnetic member 400 flying out of the movable cylinder 300 under the action of the repulsive force is avoided, and the movable cylinder 300 is ensured to move synchronously with the second magnetic member 400.
[0056] Optionally, the inner side wall of the movable cylinder 300 is further provided with a second stop surface 320 spaced apart from the second limiting hole 310, and the other end of the second magnetic member 400 abuts against the second stop surface 320. It can be understood that the second magnetic member 400 is sandwiched between the second stop surface 320 and the end of the movable cylinder 300, so that the second magnetic member 400 does not slide relative to the movable cylinder 300, ensuring that the movable cylinder 300 can move synchronously with the second magnetic member 400.
[0057] The utility model also discloses an electric two-wheeled vehicle, including a frame, a front wheel, a rear wheel and the magnetic shock absorber mentioned above, wherein there are two magnetic shock absorbers, a fixed cylinder 100 of each magnetic shock absorber is connected to the front wheel, and a movable cylinder 300 of each magnetic shock absorber is connected to the frame. Due to the magnetic shock absorber mentioned above, the electric two-wheeled vehicle has a long shock absorption stroke, timely shock absorption feedback, and a good riding experience.
