Description

Technical Field

[0001] The invention relates to the technical field of two-wheeled vehicles, in particular to a rotating component damping device and a vehicle using the rotating component damping device. Background Art

[0002] Bicycles, electric bikes and other two-wheeled vehicles are important means of transportation in modern life and are widely used. In recent years, the business model of shared bicycles has developed rapidly, further driving the development of the bicycle industry.

[0003] As bicycles and electric vehicles that can be used for public use, high requirements are placed on their performance, reliability and safety. Among them, in order to meet the requirements of standardized parking and regional operation of shared bicycles, the vehicles need to realize the functions of automatic opening and closing. However, this automatic locking of the bicycle brings more serious problems, namely safety issues. In order to cooperate with urban management, shared bicycles are required to be driven within the specified area. If the bicycle is in the process of driving, but exceeds the specified area, at this time, if the automatic locking is performed, safety problems will arise. Alternatively, if the driver misoperates the locking operation during riding, the existing automatic lock will directly lock the bicycle, and the driving speed may drop sharply from high speed to 0, which will cause the rider to fall off the shared bicycle, causing safety problems. Summary of the invention

[0004] To solve the above technical problems, an object of the present invention is to provide a rotating part damping device, which can prevent the rotating part from stopping suddenly, avoid traffic safety accidents caused by sudden stopping, and has simple assembly and low manufacturing cost. Another object of the present invention is to provide a vehicle using a rotating damping device, which can also achieve the above effect.

[0005] The technical solution of the present invention is as follows:

[0006] A rotating part damping device comprises a rotating part with a protrusion in the circumferential direction, an anti-rotation part matched with a groove formed by two adjacent protrusions, the anti-rotation part is rotatable, and a flexible structure acting on the anti-rotation part, and a flexible structure acting on the anti-rotation part, which is used to put the rotating part in a locked state.

[0007] Preferably, the flexible structure comprises a first torsion spring acting on the anti-rotation member and a first limit block capable of limiting the rotation of the anti-rotation member.

[0008] Preferably, it comprises an operating member hinged to the anti-rotation member, and a base hinged to the operating member, and the first torsion spring abuts between the anti-rotation member and the operating member, so that the anti-rotation member can rotate clockwise or counterclockwise.

[0009] Preferably, the device comprises a control mechanism connected to the operating member, and the operating member can be rotated by the control mechanism.

[0010] Preferably, the protrusion is located inside the rotating member, and the anti-rotation member, the first torsion spring, the first limit block, the operating member and the control structure are all arranged inside the rotating member.

[0011] Preferably, the protrusion is located outside the rotating member, and the anti-rotation member, the first torsion spring, the first limit block, the operating member and the control structure are all arranged outside the rotating member.

[0012] Preferably, the control structure includes a first connecting rod hinged to the operating member at one end, a second connecting rod hinged to the other end of the first connecting rod, the second connecting rod hinged to the base, and a second torsion spring arranged between the second connecting rod and the base, and a second limit block that can contact the first connecting rod to put the operating member in a self-locking state.

[0013] Preferably, it comprises a magnet disposed on a rotating member, and a Hall element fixedly disposed relative to the rotating member, wherein the Hall element cooperates with the magnet.

[0014] Preferably, the control structure includes a third limit block arranged on the operating member, and a control member hinged to the base, and the third limit block cooperates with a control groove on the control member so that when the control member swings, the third limit block can slide along the control groove.

[0015] Preferably, the control structure comprises a control member hinged to the base, and the control member can cooperate with a buckle groove on the operating member.

[0016] Preferably, the control structure comprises a control member hinged to the base, a fixing block provided on the operating member, and a slot surrounded by at least two fixing blocks, wherein the slot can be snap-connected to the control member.

[0017] A vehicle is provided, using the above-mentioned rotating part damping device, wherein the vehicle is a two-wheel vehicle or a four-wheel vehicle.

[0018] The present invention provides a damping device for a rotating part, which acts on the rotating part so that the kinetic energy of the rotating part gradually decays and the rotation speed decreases due to the influence of resistance during the rotation process. Specifically, the anti-rotation part moves toward the outer surface of the rotating part. When the anti-rotation part contacts the protrusion arranged on the circumference of the rotating part, the torsion of the rotating part and the friction resistance between the two are generated, so that the rotation speed of the rotating part gradually decreases. When the rotation speed of the rotating part is very low or stops, the anti-rotation part falls into the groove, and the groove cooperates with the anti-rotation part. After the anti-rotation part rotates into the groove, when the rotating part rotates in one direction, the flexible structure acting on the anti-rotation part gradually increases the resistance provided by the anti-rotation part, and the rotation resistance of the rotating part also increases. The rotating part is in a deceleration state. Under the continuous action of the resistance provided by the anti-rotation part, the rotating part gradually stops rotating, so that it reaches a state close to locking. When the rotating part rotates in the opposite direction, the flexible structure provides a constant resistance to the anti-rotation part, and the resistance is greater than or equal to the kinetic energy of the rotating part when it rotates, and the rotating part is in a direct locking state. Since the speed of the rotating parts is gradually decelerated to zero, the instantaneous load impact on the wheels will be reduced, and driving safety accidents caused by sudden stops can be avoided. The mechanical damping method is used to reduce the speed of the rotating parts, thereby reducing the driving speed of the wheels. The assembly is simple and the economic cost is low.

[0019] The vehicle provided by the present invention applies the above-mentioned rotating part damping device, which can also avoid driving safety accidents caused by sudden stops. The mechanical damping method is used to reduce the rotating speed of the rotating part, thereby reducing the driving speed of the wheel. The assembly is simple and the economic cost is low.

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0037] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention.

[0038] Please Figures 1 to 14 As shown, the present invention provides a rotating part damping device, including a rotating part 1 with a protrusion provided in the circumferential direction, an anti-rotation part 4 matched with a groove 3 formed by two adjacent protrusions 2, the anti-rotation part 4 is rotatable, and a flexible structure acting on the anti-rotation part 4 is used to enable the anti-rotation part 4 to contact with the protrusion 2, or be inserted into the groove 3, so that the rotating part is in a deceleration state.

[0039] The damping device for rotating parts acts on the rotating part 1, so that the kinetic energy of the rotating part 1 gradually decays and the speed decreases due to the influence of resistance during the rotation process. Specifically, when the anti-rotation part 3 moves toward the outer surface of the rotating part 1, and the anti-rotation part 4 contacts the protrusion 2 arranged on the circumference of the rotating part 1, the torsion of the rotating part 1 and the friction resistance between the two generate, so that the speed of the rotating part 1 gradually decreases. When the speed of the rotating part 1 is very low or stops, the anti-rotation part 4 falls into the groove, and the groove 3 cooperates with the anti-rotation part 4. After the anti-rotation part 4 rotates into the groove 3, when the rotating part 1 rotates in one direction, the flexible structure acting on the anti-rotation part 4 gradually increases the resistance provided by the anti-rotation part 4, and the rotation resistance of the rotating part 1 also increases, and the rotating part 1 is in a deceleration state; under the continuous action of the resistance provided by the anti-rotation part 4, the rotating part 1 gradually stops rotating, so that it reaches a state close to locking. When the rotating part 1 rotates in the opposite direction, the flexible structure provides a constant resistance to the anti-rotation part 4, which is greater than or equal to the kinetic energy of the rotating part 1 when rotating, and the rotating part 1 is in a direct locking state. Since the speed of the rotating part 1 is gradually decelerated to zero, the instantaneous load impact on the wheel will be reduced, and driving safety accidents caused by sudden stops can be avoided. The mechanical damping method is used to reduce the speed of the rotating part 1, thereby reducing the driving speed of the wheel. The assembly is simple and the economic cost is low.

[0040] Among them, the flexible structure includes a first torsion spring 5 acting on the anti-rotation member 4, and a first limit block 6 that can limit the rotation of the anti-rotation member 4. When the rotating member 1 rotates clockwise, one side wall of the groove 3 contacts the anti-rotation member 4. Due to the torsion of the first torsion spring 5, the anti-rotation member 4 provides resistance to the rotating member 1. As the rotation angle of the rotating member 1 increases, the resistance is also gradually increased. According to the principle of action and reaction, the rotating member 1 is in a deceleration state. When the rotating member 1 rotates counterclockwise, the other side wall of the groove 3 contacts the anti-rotation member 4, and the first limit block 6 abuts against the anti-rotation member 4. The first limit block 6 limits the rotation of the anti-rotation member 4. When the rotating member 1 rotates counterclockwise, the force applied to the anti-rotation member 4 through the side wall of the groove 3, the faster the rotating speed of the rotating member 1, the greater the force applied to the anti-rotation member 4, and the greater the reaction resistance provided by the first limit block 6, so that the rotating member 1 is in a static locked state. It can be seen that the flexible structure can slow down the clockwise rotation of the rotating member 1. Under the continuous action of the resistance provided by the anti-rotation member 4, the kinetic energy of the rotating member 1 is gradually consumed, and the rotating member 1 gradually stops rotating, so that it reaches a nearly locked state. The rotating member 1 is locked (prevented from rotating) when it rotates counterclockwise. The orientation position of the anti-rotation member 4 is adjusted, and the first torsion spring 5 and the first limit block 6 are adaptively adjusted. The problems solved and the effects produced are the same, and should also be understood to be within the protection scope of this technical solution.

[0041] For example, Figure 1 In the figure, when the anti-rotation component 4 is located on the right side of the central axis, the rotating component 1 decelerates clockwise and is locked when rotating counterclockwise. If the anti-rotation component 4 is adjusted to the left side of the central axis and the first torsion spring 5 and the first limit block 6 are adaptively adjusted, the rotating component 1 will be locked clockwise and decelerated counterclockwise.

[0042] The damping device of the rotating member 1 provided in the present application is as follows: Figure 5 As shown, it is particularly suitable for the technical fields such as bicycles and electric vehicles. The commonality in this field is that the wheels can only travel in one direction, that is, the wheels can only move forward and not backward. Unlike cars, cars can move forward and backward. In order to facilitate the understanding of the essence of the technical solution of this application, the sharing unit is now used as an example for explanation. Compared with the prior art, the rotating part 1 damping device provided by this application is adopted. When it is necessary to stop driving during driving, the rotating part 1 is decelerated, and the wheel stops after deceleration, realizing a function similar to a lock. The rotating part damping device provided by this application can perform a function similar to a lock, but compared with the shared bicycle locks on the market, it adopts mechanical braking, has a simple structure, is easy to assemble, and once there is a loss of parts, it is easy to disassemble and assemble, and then the entire device has strong interchangeability. Whether it is manufacturing, maintenance and installation costs are very low, it has incomparable advantages over shared bicycle locks on the market.

[0043] In the embodiments provided by the present invention, Figures 1 to 5As shown, the damping device of the rotating member 1 also includes an operating member 7 hinged to the anti-rotation member 4, a base 8 hinged to the operating member 7, and a first torsion spring 5 abutting between the anti-rotation member 4 and the operating member 7, so that the anti-rotation member 4 can rotate clockwise or counterclockwise. One end of the operating member 7 can rotate around the hinge point in the plane on the base 8, and the other end of the operating member 7 is hinged to the anti-rotation member 4. The setting of the operating member 7 can drive the anti-rotation member 4 to enter the groove 3 or disengage from the groove 3. Specifically, it can be configured that when the operating member 7 approaches the outside of the rotating member 1, the anti-rotation member 4 contacts the multiple protrusions 2 one by one. During the rotation process, the rotating member 1 needs to continuously overcome the friction between the anti-rotation member 4 and the protrusions 2, as well as the pressure decomposed by the gravity applied from top to bottom by the anti-rotation member 4, so the kinetic energy of the rotating member 1 is gradually consumed. When the rotation speed of the rotating member 1 is very low or stops, the anti-rotation member 4 falls into the groove 3, and the groove 3 cooperates with the anti-rotation member 4, and the rotating member 1 further decelerates until it stops. Figure 1 For example, the anti-rotation member 4 needs to overcome the resistance provided by the first torsion spring 5 to move out of the groove 3, so that the rotation member 1 is in a locked state in the counterclockwise direction and reaches a nearly locked state in the clockwise direction. The nearly locked state means that if the rotating member 1 overcomes the gravity of the anti-rotation member 4 and the torsion of the first torsion spring 5, the anti-rotation member 4 will be separated from the groove 3 and act on the surface of the raised portion 2 on the rotating member 1, and then the rotating member 1 is in an ultra-low speed driving state, and the riding is not smooth. Therefore, in addition to providing resistance to the deceleration of the rotating member 1, the first torsion spring 5 can also reset the anti-rotation member 4.

[0044] The damping device of the rotating member 1 can be locked during the rotation of the rotating member 1, or it can be locked as shown in FIG. Figure 3 The rotation member 1 is locked when it is in a stationary state. After locking, the first torsion spring 5 provides a continuous and sufficient load torque to the anti-rotation member 1, which acts on the rotation member 1, so that the rotation member 1 is in a locked state.

[0045] The damping device of the rotating member 1 includes a control mechanism 9 connected to the operating member 7, and the operating member 7 can be rotated by the control mechanism 9. The control mechanism 9 is connected to the operating member 7, and the operating member 7 is hinged to the anti-rotation member 4. The control mechanism 9 pulls the operating member 7 to enable the anti-rotation member 4 to enter the groove 3 or disengage from the groove 3.

[0046] Furthermore, if Figures 1 to 5As shown, the control structure includes a first link 91 hinged at one end to the operating member 7, a second link 92 hinged at the other end of the first link 91, the second link 92 hinged to the base 8, and a second torsion spring 93 disposed between the second link 92 and the base 8, and a second stopper 94 that can contact the first link 91, so that the operating member 7 is in a self-locking state. A total of three hinge points are arranged on the first link 91 and the second link 92, and the first link 91 and the second link 92 are configured so that when the first link 91 and the second link 92 swing to a dead point position away from the second stopper 94, the second torsion spring 93 starts to store energy, and it is laborious to open the operating member 7, so that the anti-rotation member 4 will not easily fall into the groove. After receiving the locking command, the second connecting rod 92 no longer bears the tension, and the second torsion spring 93 begins to release the compression energy, so that the anti-rotation member 4 quickly approaches the outer side of the protrusion 2 and contacts it. After the rotating member 1 gradually decelerates, the anti-rotation member 4 enters the groove 3. When one side of the first connecting rod 91 abuts against the second limit block 94, the operating member 7 is in a self-locking state at this time. It is ensured that when the rotating member 1 is in the locked state, the operating member 7 will not move easily, thereby ensuring the reliability of the locking. Through the connecting rod mechanism composed of the first connecting rod 91 and the second connecting rod 92 and the second limit block 94, the operating member 7 can be in a self-locking state regardless of the direction in which the first connecting rod 91 and the second connecting rod 92 swing, especially when the first connecting rod 92 and the second connecting rod 92 are in the dead point position, the rotating member 1 is rotating, but the operating member 7 will not fall off. It can be understood that during the driving of the bicycle, the operating member 7 will not fall off, and the anti-rotation member 4 connected to the operating member 7 will not fall into the groove 3. Unless the first connecting rod 91 and the second connecting rod 92 are released from the dead point position, the self-locking structure of the operating member 7 can effectively avoid misoperation during driving and improve driving safety.

[0047] When the first connecting rod 91 and the second connecting rod 92 are at the dead point position, the second torsion spring 93 is in the energy storage process. Once the positions of the first connecting rod 91 and the second connecting rod 92 are changed, the second torsion spring 93 releases energy instantly, and the first connecting rod 91 and the second connecting rod 92 quickly return to their initial positions. The setting of the second torsion spring 93 improves the response time of the control structure.

[0048] In the embodiment provided by the present invention, the protrusion 2 can be arranged inside the rotating member 1, and the anti-rotation member 4, the first torsion spring 5, the first limit block 6, the operating member 7 and the control structure are all arranged inside the rotating member 1. Alternatively, the protrusion 2 is located outside the rotating member 1, and the anti-rotation member 4, the first torsion spring 5, the first limit block 6, the operating member 7 and the control structure are all arranged outside the rotating member 1. Regardless of the setting method, it does not deviate from the essence of the technical solution and is within the protection scope of this application. It can be adaptively adjusted according to actual conditions or different application scenarios.

[0049] In the embodiment provided by the present invention, a magnet is provided on the rotating member 1, and a Hall element is provided on the base 8, and the Hall element is used in conjunction with the magnet. The Hall element is a magnetic sensitive element, which is used in conjunction with the magnet on the rotating body to measure the rotation speed of the rotating body. When the rotating body rotates, each time the magnet passes through the Hall element, the Hall element sends a signal, and then a pulse signal is obtained. The pulse signal can also be directly output through the Hall element. The interval time between two pulse signals is the period. The rotation speed can be converted using the period, or the number of pulses per unit time can be counted and then converted to the rotation speed. This embodiment can be applied to a bicycle or an electric vehicle. When the measured rotation speed, that is, the driving speed, exceeds the limit value, the vehicle speed can be intervened to ensure the driving safety of the driver. When the speed is detected, the control mechanism can selectively control whether the anti-rotation member falls into the groove, which can be configured in the vehicle controller according to actual needs.

[0050] In the embodiments provided by the present invention, Figure 6 and Figure 8 As shown, the control structure includes a third limit block 95 provided on the operating member 7, and a control member hinged to the base 8. The third limit block 95 cooperates with a control groove 97 on the control member 96, so that when the control member 96 swings, the third limit block 95 can slide along the control groove 97. When the third limit block 95 moves to one end of the control groove 97, the operating member 7 is self-locked, the state of the operating member 7 does not change, the anti-rotation member 4 is disengaged from the groove 3, and the rotating member 1 rotates normally; when the third limit block 95 moves to the other end of the control groove 97, the anti-rotation member 4 falls into the groove 3.

[0051] Another embodiment of the control structure is as follows: Fig. 9 and Fig.11 As shown, the control structure includes a control member 96 hinged to the base 8, and the control member 96 can be matched with the buckle groove 98 on the operating member 7. When the control member 96 contacts the side wall of the buckle groove 98, so that the control member 96 and the operating member 7 reach a balanced state, the anti-rotation member 4 falls into the groove 3; when the control member 96 is snap-fitted with the buckle groove 98, the operating member 7 rotates, and the control member 96 provides the operating member 7 with a pulling force that is always upward, so that the anti-rotation member 4 is disengaged from the groove 3, and the rotating member 1 rotates normally.

[0052] There is also an embodiment of the control structure, such as Fig.12 and Fig.14As shown, the control structure includes a control member 96 hinged to the base 8, a fixed block arranged on the operating member 7, and a slot surrounded by at least two fixed blocks, and the slot can be snap-connected with the control member 96. Preferably, three fixed blocks can be set, one of which is always in contact with the control member 96, and the second fixed block is in contact with the other side of the control member 96. There are two contact points between the slot formed by the two control blocks and the control member 96, so that the control member 96 is stuck in the slot, thereby limiting the displacement of the operating member 7 and making it in a self-locking state. The third fixed block is set on the swing path of the control member 96, so that the swing position of the control member 96 changes, and there are always two fixed blocks to clamp the control member 96. When the first fixed block 99, the second fixed block 100 and the control member 96 act together, the anti-rotation member 4 falls into the groove 3 of the rotating member 1; when the first fixed block 99, the second fixed block 100 and the control member 96 act together, the anti-rotation member 4 is separated from the groove 3 of the rotating member 1, and the rotating member 1 can rotate normally.

[0053] It should be noted that the specific structure of the control structure is not limited to the embodiments provided in the present application. It should also be understood that the state of the control member 96 is fixed by changing the state of the control member 96, so that when the operating member 7 is stationary and self-locking, the anti-rotation member 4 falls into the groove 3 or disengages from the groove 3. All embodiments, without departing from the technical essence, should also be understood to fall within the protection scope of the present application.

[0054] To improve driving safety during riding, we can start from the following three points:

[0055] First, when a Hall signal is detected, that is, the rotating member 1 is rotating, the control mechanism does not execute the locking instruction, that is, the anti-rotation member will not fall into the groove.

[0056] Second, when the rotating part rotates at a high speed, the operating part 7 and the anti-rotation part 4 are an integral whole relative to the rotating part 1. The protrusion 2 on the rotating part pushes the operating part 7 and the anti-rotation part 4 outward. In order to overcome the friction between the operating part 7 and the anti-rotation part 4 and the protrusion 2, as well as the pressure decomposed by the gravity of the operating part 7 and the anti-rotation part 4, the kinetic energy of the rotating part 1 is gradually consumed, thereby achieving the purpose of speed reduction, and the rotating part 1 will not stop and lock suddenly.

[0057] Third, when the rotating part 1 rotates at a low speed, the anti-rotation part 4 falls into the groove 3. When the torque applied by the protrusion 2 of the rotating part 1 is greater than the torque of the first torsion spring 5 on the anti-rotation part 4, the anti-rotation part 4 is pushed up to rotate without sudden stop.

[0058] The embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referenced to each other.

[0059] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
