[0034] The technical solutions in the embodiments of the present application will be further clearly and completely described below in conjunction with the accompanying drawings. However, it should be noted that the following embodiments are only some of the preferred embodiments in the present application and do not involve all the embodiments covered by the technical solutions of the present application.

[0035] It should be noted that, in the description of this application, when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Figure 1 Shown is a schematic diagram of the unlocking principle of a brake wire lock according to an embodiment of the present application, wherein a first winding wheel 5 and a second winding wheel 6 are provided on the brake wire lock 1, and the first winding wheel 5 and the second winding wheel 6 are arranged opposite to each other, and the brake wire 2 passes between the first winding wheel 5 and the second winding wheel 6. The working principle of the technical solution provided by the present application is to apply tension to the brake wire 2 so that the brake wire 2 is tightened to lock the vehicle brake, thereby achieving locking of the vehicle. In order to provide tension to the brake wire 2, an embodiment of the present application adopts a method of utilizing the first winding wheel 5 and the second winding wheel 6 as the two end points of the diameter, and driving the first winding wheel 5 and the second winding wheel 6 to perform circular motion when the driving unit rotates forward. During the circular motion, the line connecting the two end points can intersect with the brake wire 2, and further pull the brake wire 2 to produce a larger displacement, and finally the brake wire 2 pulls the vehicle brake to lock. Specifically, Figure 2 shown.

[0038] Figure 2The figure shows a schematic diagram of the locking principle of a brake wire lock according to an embodiment of the present application. With the first winding wheel 5 and the second winding wheel 6 as two points on the diameter, the first winding wheel 5 and the second winding wheel 6 are driven to perform circular motion when the driving unit rotates forward, and the brake wire 2 is pulled to undergo elastic deformation. In order to prevent the brake wire 2 from being damaged by excessive pulling, such as breakage, the rotation angles of the first winding wheel 5 and the second winding wheel 6 need to be reasonably set, such as a rotation angle of 100 degrees to 120 degrees for the circular motion. Those skilled in the art can design a more reasonable rotation angle based on the relevant parameters of the brake wire 2 and the relevant data of the vehicle brake in actual application.

[0039] Furthermore, in order to control the rotation angle, at least one switch, such as a limit switch, is provided on the wire lock 1. When the first winding wheel 5 and / or the second winding wheel 6 triggers the switch, the controller (not shown) receives the switch signal and issues a stop rotation instruction to the drive unit. The drive unit stops rotating, and the first winding wheel 5 and the second winding wheel 6 wind the wire 2 and keep the wire 2 in a reasonably taut state. Figure 1 In order to facilitate the control of the switch, the first winding wheel 5 and the second winding wheel 6 are placed on the same plane. At the same time, the height of the plane where the top of the first winding wheel 5 is located is higher than the height of the plane where the top of the second winding wheel 6 is located. The plane where the switch is installed is higher than the plane where the top of the second winding wheel 6 is located. When the first winding wheel 5 and the second winding wheel 6 rotate, only the top of the first winding wheel 5 can trigger the switch. Figure 2 When the first winding wheel 5 pulls the brake wire 2 and rotates to the maximum displacement, the second switch 4 is triggered. The second switch 4 sends a signal to the controller, and the controller sends a stop rotation instruction to the drive unit. After receiving the stop rotation instruction, the drive unit stops rotating, thereby keeping the brake wire 2 in a tensioned state to ensure that the brake is locked.

[0040] Combine Figure 1 and Figure 2 When the vehicle needs to be opened, the driving unit is reversed, thereby driving the first winding wheel 5 and the second winding wheel 6 to rotate, so that the brake wire 2 is released and restored to the state as shown in FIG. Figure 1 As shown in the position, the first switch 3 is triggered by the first winding wheel 5. After the first switch 3 is closed, a signal is sent to the controller. After receiving the signal, the controller sends a stop rotation instruction to the drive unit. After receiving the signal, the drive unit stops rotating, so that the first winding wheel 5 and the second winding wheel 6 are kept in the Figure 1 In the position shown, the brake cable 2 can pass through the brake cable lock 1 without any obstacles, releasing the brake and making the vehicle usable.

[0041] It should be noted that, in the embodiment provided by the present application, the circular motion uses the first winding wheel 5 and the second winding wheel 6 as the two endpoints of the diameter, but this does not exhaust all the embodiments of the present application. For example, the first winding wheel 5 and the second winding wheel 6 are any two points on the circumference diameter, and the rotation center can be the midpoint of the distance between the first winding wheel 5 and the second winding wheel 6, or any point therebetween. In addition, according to the elastic deformation-related data of the brake wire 2, any one point of the first winding wheel 5 and the second winding wheel 6 is set as a fixed point and the other point as a moving point. The moving point rotates around the fixed point and tightens the traction brake wire 2, which can also achieve the locking of the vehicle. Therefore, those skilled in the art can design a reasonable solution according to actual needs.

[0042] Furthermore, in another embodiment of the present application, the two winding wheels trigger different switches respectively when rotating to realize the functions of locking and unlocking. For example, when rotating forward to lock, the first winding wheel 5 triggers the first switch 3 and the drive unit stops rotating; when rotating reverse to unlock, the second winding wheel 6 triggers the second switch 4 and the drive unit stops rotating.

[0043] Furthermore, another embodiment of the present application, based on the same working principle as the above embodiment, can optionally provide a winding wheel, the winding wheel being perpendicular to its rotation plane, the brake wire being parallel to the plane and tangent to the winding wheel, and when the winding wheel makes a curved motion in the direction tangent to the brake wire, such as a circular motion, it can drive the winding wheel to push and tighten the brake wire, thereby locking the vehicle brake; when reversing, it can return to a position tangent to the brake wire, causing the brake wire to release the vehicle brake. Those skilled in the art can design a reasonable curved motion trajectory through the technology of relevant parameters to achieve locking of the vehicle brake.

[0044] Figure 3 The figure shows the unlocked state of a gate wire lock according to an embodiment of the present application, wherein a driving unit (not shown) is provided in the housing 7 of the gate wire lock 1, and a first winding wheel 5 and a second winding wheel 6 are provided on the top of the housing 7. The gate wire 2 passes between the first winding wheel 5 and the second winding wheel 6 and is roughly in the same plane as the second winding wheel 6. The first winding wheel 5 is higher than the second winding wheel 6 to facilitate triggering the switch. Therefore, the plane where the first switch 3 and the second switch 4 are located is higher than the height where the gate wire 2 and the second winding wheel 6 are located, and are fixed to the housing 7 by a support plate (not shown). However, in order to clearly show the internal structure of the gate wire lock 1, the structure of the support plate will be shown. Figure 5 Provide explanation.

[0045] In this embodiment, the first winding wheel 5 and the second winding wheel 6 are connected to one end face of the ratchet assembly 8. The ratchet assembly 8 is provided on the housing 7, and its other end face is connected to the driving unit. The driving unit drives the ratchet assembly 8 to rotate forward or reverse, thereby driving the first winding wheel 5 and the second winding wheel 6 to rotate in two different directions, thereby tightening or loosening the brake cable 2. In addition, the portion of the brake cable 2 passing through the housing 7 is clamped on the two ends 71 ​​of the housing 7 in a sleeve manner, so that it does not affect the expansion and contraction of the brake cable 2.

[0046] Figure 4 The figure shows the brake wire lock in the locked state of an embodiment of the present application. When the driving unit rotates forward, the ratchet assembly 8 is driven to rotate and the first winding wheel 5 and the second winding wheel 6 are driven to rotate. The first winding wheel 5 and the second winding wheel 6 respectively contact the brake wire 2 and pull the brake wire 2 while rotating, thereby deforming the brake wire 2. Figure 3 As shown, when the driving unit rotates forward, it pushes the ratchet assembly to rotate, causing the first winding wheel 5 and the second winding wheel 6 to rotate and pulling the brake wire 2 to move.

[0047] Preferably, in order to enable the first winding wheel 5 and the second winding wheel 6 to pull the brake wire 2 at the first time of rotation, the gate wire 2 can be tangent to the first winding wheel 5 and the second winding wheel 6 respectively when passing through the space between the first winding wheel 5 and the second winding wheel 6, and the two tangent points are located in front of the first winding wheel 5 and the second winding wheel 6 when rotating counterclockwise. The counterclockwise mentioned here refers to when the drive unit rotates forward, and the locking function can be achieved when the drive unit rotates counterclockwise. In other embodiments, it can also be set to rotate clockwise to achieve the locking function, that is, when the gate wire lock 1 needs to achieve the locking function, the drive unit rotates clockwise, and the tangent point between the gate wire 2 and the first winding wheel 5 and the second winding wheel 6 is located in front of the first winding wheel 5 and the second winding wheel 6 when moving clockwise, thereby achieving the pushing of the gate wire 2 and pulling the gate wire 2 to deform.

[0048] Figure 5Shown is a cross-sectional view of a brake cable lock according to an embodiment of the present application. The brake cable lock 1 includes a first switch 3, a second switch 4, a first winding reel (not shown), a second winding reel 6, a housing 7, a ratchet assembly 8, a support plate 9, a drive unit 10, a controller (not shown), a transmission assembly 11, and a cover plate 12. The drive unit 10 is disposed within the housing 7 and includes a driver, such as a motor. The output end of the drive unit 10 is connected to the transmission assembly 11, which is connected to the ratchet assembly 8, thereby transmitting power from the drive unit 10 to the ratchet assembly 8, driving the ratchet assembly 8 to rotate. The first switch 3 and the second switch 4 are fixed to the housing 7 via the support plate 9, allowing the brake cable 2 to pass through the gap between the housing 7 and the support plate 9. A sleeve 21 is provided at the end of the housing 7 where the brake cable 2 passes. This allows the brake cable 2 to be locked into the housing 7 without restricting its expansion and contraction within the sleeve 21.

[0049] The ratchet assembly 8 includes a ratchet 81 and a first pawl 82. The first pawl 82 is disposed on the outer ring of the ratchet 81 and engages with the outer ring teeth of the ratchet 81 to limit the unidirectional rotation of the ratchet 81. The structure of the ratchet 81 includes a circular base plate, one end surface of which is provided with outer ring teeth that engage with the first pawl 82, and the other end surface of the circular base plate is connected to the first winding wheel 5 and the second winding wheel 6, so that the circumferential rotation of the first winding wheel 5 and the second winding wheel 6 is synchronized with the rotation of the ratchet 81. The specific details of the ratchet assembly 8 will be described in detail later.

[0050] The transmission assembly 11 includes a transmission block 111, a second pawl 112, and a transmission plate 113. The transmission assembly 11 is sleeved onto the inner ring of the ratchet assembly 8. The transmission block 111 is connected to the output end of the drive unit 10. The second pawl 112 is sleeved onto the transmission block 111 and engages with the inner ring teeth of the ratchet 81 to limit the unidirectional rotation of the ratchet 81. The transmission plate 113 is disposed at the bottom of the transmission block 111 and rotates synchronously with the transmission block 111. The specific details of the transmission assembly 11 will be described in detail later.

[0051] In actual use, when the vehicle needs to be locked, the user scans a QR code or opens a client application and enters a lock command. After receiving the command, the drive unit 10 begins to rotate forward, driving the transmission assembly 11 to rotate. The second pawl 112 on the transmission assembly 11 extends into the inner ring teeth of the ratchet 81 and pushes the ratchet assembly 8 to rotate. At this time, the first pawl 82 can slide along the outer ring teeth of the ratchet 81 and does not restrict the rotation of the ratchet 81. The ratchet assembly 8 drives the first winding wheel 5 and the second winding wheel 6 to rotate, thereby tightening the brake cable 2 and locking the vehicle brake, thus achieving the function of locking the vehicle.

[0052] When the vehicle needs to be unlocked, the user scans the QR code or opens the client application and enters the unlocking command. The drive unit 10 receives the command and reverses. At this time, the transmission assembly 11 reverses, causing the second pawl 112 to slide around the inner teeth of the ratchet 81 and not provide thrust to the ratchet 81. At the same time, when the transmission plate 113 at the bottom of the transmission block 111 reverses, multiple protrusions are arranged on its outer circumference. When the multiple protrusions rotate, they can intermittently push the first pawl 82 to release the ratchet 81. At the moment when the protrusions push the first pawl 82 to release the ratchet 81, the ratchet assembly 8 is in a free state. Due to the spring on the brake and the rebound effect of the brake cable 2, the ratchet assembly 8 can gradually return to its initial state, gradually reducing the traction force on the brake cable 2 until the brake cable 2 is completely released. At this time, the brake is free of external force, ensuring the normal use of the vehicle.

[0053] It should be noted that the forward rotation mentioned in this specification is relative to the reverse rotation. Figure 1-Figure 5 In the illustrated embodiment, forward rotation refers to counterclockwise rotation of the drive unit 10, and reverse rotation refers to clockwise rotation of the drive unit 10. The drive unit 10 and the transmission assembly 11 can rotate in the same direction, while the ratchet assembly 8 rotates in the opposite direction to the drive unit 10. During forward rotation, the first winding wheel 5 and the second winding wheel 6 can wind and tighten the brake cable 2, and during reverse rotation, the brake cable 2 can be released and restored to its natural state. However, in some other embodiments, forward rotation can also correspond to clockwise rotation, and reverse rotation to counterclockwise rotation. Those skilled in the art can design different rotation directions according to different structures. Figure 6 Shown is a stereoscopic view of a ratchet assembly according to an embodiment of the present application, from which the ratchet assembly 8 and the transmission assembly 11 sleeved in the ratchet assembly 8 can be seen. The ratchet assembly 8 includes a ratchet 81 and a first pawl 82. Specifically, the transmission assembly 11 is provided on the inner ring of the ratchet 81, and the matching first pawl 82 is provided on the outer ring teeth. Preferably, the number of the first pawls 82 is preferably three and is evenly distributed on the outer ring teeth of the ratchet 81; in contrast, the first winding wheel 5 and the second winding wheel 6 are provided on the side of the ratchet 81 away from the transmission assembly 11. The transmission assembly 11 includes a transmission block 111, a second pawl 112, a transmission plate (not shown) and a spring leaf 114. The second pawl 112 is sleeved on the transmission block 111, and its number is preferably 3, and it is evenly distributed along the circumference of the transmission block 111. In order to ensure that the second pawl 112 can freely extend and retract in the radial direction of the transmission block 111, a spring sheet 114 is provided at the center of the transmission block 111, so that the outer end of the second pawl 112 extends out of the transmission block 111 when there is no external force, and can be retracted into the transmission block 111 when it is under force.

[0054] Figure 7The figure shows a three-dimensional view of a transmission assembly according to an embodiment of the present application. The transmission assembly 11 includes a transmission block 111, a second pawl 112, a transmission plate 113, and a spring leaf (not shown). One end face of the transmission block 111 is sleeved on the output end of the drive unit 10, and the other end face is provided with a transmission plate 113. The second pawl 112 is sleeved in the transmission block 111 and is arranged along the circumference of the transmission block 111. In a natural state, the outer end of the second pawl 112 extends out of the transmission block 111. The outer diameter of the transmission plate 113 is larger than the outer diameter of the circle on which the outermost end of the second pawl 112 is located. The transmission plate 113 is provided with a plurality of protrusions 115 in the radial direction. Preferably, the protrusions 115 include three. When the transmission plate 113 moves synchronously with the transmission block 111, the protrusions 115 on the transmission plate 113 can act on the first pawl 82, thereby pushing the first pawl 82 to release the ratchet 81.

[0055] Figure 8 The figure shows an assembly diagram of a ratchet assembly and a transmission assembly according to an embodiment of the present application. When the driving unit 10 rotates forward, as shown in FIG. Figure 8 In the state shown, the transmission assembly 11 rotates forward, combined with Figure 6 As shown, the transmission block 111 rotates with the drive unit 10, and the second pawl 112 can rotate together with the transmission block 111. At this time, the outer end of the second pawl 112 can be inserted into the inner ring teeth of the ratchet 81, thereby pushing the ratchet 81 to rotate. At the same time, the first pawl 82 can slide when the ratchet 81 rotates and does not restrict the rotation of the ratchet 81. Although the transmission plate 113 pushes the first pawl 82 to intermittently release the ratchet 81 when it rotates, since the ratchet 81 rotates under the push of the second pawl 112, even if the first pawl 82 releases the ratchet 81, it will not cause the ratchet 81 to reverse. The ratchet 81 rotates, driving the first winding wheel 5 and the second winding wheel 6 on the back to push the brake cable 2, thereby locking the brake.

[0056] When the drive unit 10 reverses, the second pawl 112 is pushed into the transmission block 111 by the inner ring teeth of the ratchet 81, and no circumferential thrust is generated on the ratchet 81. At the same time, since the transmission plate 113 pushes the first pawl 82 to intermittently release the ratchet 81 when rotating, the ratchet 81 will be intermittently in a free state. At this time, the brake wire 2 will rebound under the action of the return spring thereon, and drive the ratchet 81 to rotate to its initial state, eventually causing the brake wire lock 1 to release the brake wire 2, so that the brake is in the open state.

[0057] Figure 9What is shown is a structural diagram of a support plate of an embodiment of the present application, wherein the support plate 9 is used to fix the first switch 3 and the second switch 4, and can ensure that the first winding wheel 5 can trigger the first switch 3 and the second switch 4 when rotating. Specifically, an arc guide rail 91 is provided on the support plate 9, so that the first winding wheel 5 can pass through the support plate 9 and reciprocate on the arc guide rail 91. Therefore, the size design of the arc guide rail 91 needs to be consistent with the movement trajectory of the first winding wheel 5. In addition, a plurality of mounting holes 92 are provided on the support plate 9 for fixing the first switch 3 and the second switch 4. It should be noted that, Figure 9 The support plate shown is only a preferred embodiment provided in this application. Those skilled in the art can design a reasonable support plate 9 according to actual needs.

[0058] The brake cable lock provided by the present application utilizes the contraction of the brake cable on the vehicle brake to lock the vehicle. When the brake cable passes through the brake cable lock, the drive unit is connected to the winding wheel through the ratchet assembly provided on the brake cable lock, so that the winding wheel can rotate in different directions. When rotating forward, the winding wheel can pull the brake cable to generate tension in the brake cable, thereby locking the vehicle brake; when rotating reversely, the winding wheel can release the brake cable to restore the brake cable to its natural state, ensuring that the vehicle brake is open. The technical solution provided by the present application does not require an additional lock structure for the vehicle, but uses the vehicle's own brake to lock. It can be set at any position on the frame or hidden in the frame. Compared with the traditional lock structure, the brake cable lock of the present application has a simple structure, beautiful appearance, is not easily damaged during use, has a high safety factor, and can greatly improve the user's riding experience in conjunction with the use of mobile Internet, and has good market application value.

[0059] The present application provides a vehicle, including the brake cable lock mentioned above, which is installed on the vehicle frame and can be connected to the brake cable of the vehicle. Figure 3 In a preferred embodiment, the brake wire 2 of the vehicle is installed at the two ends 71 ​​of the brake wire lock 1 and can pass through the space between the first winding wheel 5 and the second winding wheel 6. Therefore, when the first winding wheel 5 and the second winding wheel 6 rotate, they can gradually approach and pull the brake wire 2 to deform, thereby tightening the brake wire 2 and locking the vehicle brake. When the first winding wheel 5 and the second winding wheel 6 rotate in the opposite direction, they can return to the original position. Figure 3 In the state shown, the brake wire 2 is gradually released, thereby releasing the brake.

[0060] The technical solution provided in this application can use the vehicle's brake wire to open and lock the vehicle. The brake wire lock can be hidden in the vehicle frame without the need for additional equipment. It has a novel structure, is beautiful and elegant, and effectively improves the user experience.

[0061] also, Figure 10The following is a flow chart of a vehicle lock opening and closing method according to an embodiment of the present invention. Figure 1 , including the gate line lock described above, further comprising the following steps:

[0062] S111: starting the driving unit to rotate forward to drive the ratchet assembly to rotate, wherein the ratchet assembly is provided with a winding wheel;

[0063] The driving unit 10 is connected to the ratchet assembly 8 and can drive the ratchet assembly 8 to rotate. A first winding wheel 5 and a second winding wheel 6 are set on the side of the ratchet assembly 8 away from the driving unit 10. The driving unit 10 is set to the locking direction when it rotates forward.

[0064] S112: When the winding wheel rotates forward along with the ratchet assembly, the brake wire is tightened to lock the vehicle brake, thereby locking the vehicle brake;

[0065] When the driving unit 10 rotates forward, it is the locking direction. At this time, the first winding wheel 5 and the second winding wheel 6 can gradually approach and tighten the brake wire 2 after rotation. After the brake wire 2 is tightened, the brake is locked, thereby achieving the locked state of the vehicle.

[0066] S113: starting the driving unit to reverse and drive the ratchet assembly to rotate;

[0067] After the vehicle is locked, when it is necessary to open the vehicle, the drive unit 10 is started to reverse, thereby driving the ratchet assembly 8 to reverse, and the ratchet assembly 8 can drive the first winding wheel 5 and the second winding wheel 6 provided thereon to rotate after reversing.

[0068] It should be noted here that forward rotation and reverse rotation are relative concepts, mainly to express that the two rotation directions are opposite. In some embodiments, there may also be a forward rotation to unlock and a reverse rotation to lock.

[0069] S114: When the winding wheel rotates in reverse with the ratchet assembly, the brake wire is released to release the vehicle brake for unlocking.

[0070] When the first winding wheel 5 and the second winding wheel 6 are reversed along with the ratchet assembly 8, the tightened brake wire 2 can be gradually loosened, so that the brake wire 2 returns to its natural state, thereby releasing the vehicle brake and finally achieving the unlocked state of the vehicle.

[0071] Furthermore, Figure 11 The following is a flow chart of a vehicle lock opening and closing method according to an embodiment of the present invention. Figure 2 , further comprising the following steps:

[0072] S121: The drive unit is connected to the transmission assembly, and the transmission assembly is sleeved in the ratchet assembly;

[0073] A transmission assembly 11 is provided between the drive unit 10 and the ratchet assembly 8 . One end of the transmission assembly 11 is connected to the output end of the drive unit 10 , and the other end is sleeved in the ratchet assembly 8 . The transmission assembly 11 drives the ratchet assembly 8 to rotate.

[0074] S122: The ratchet assembly includes a first pawl and a ratchet, and the transmission assembly includes a second pawl and a transmission plate, wherein the first pawl is disposed on the outer ring of the ratchet, and the second pawl is disposed on the inner ring of the ratchet;

[0075] The ratchet assembly 8 includes a ratchet 81 and a first pawl 82. The transmission assembly 11 includes a transmission block 111, a second pawl 112, a transmission plate 113, and a spring (not shown). The first pawl 82 is located on the outer ring of the ratchet 81, and the second pawl 112 is inserted into the inner ring of the ratchet 81. When the drive unit 10 drives the transmission assembly 11 to rotate, the second pawl 112 can push the ratchet 81 to rotate in one direction.

[0076] S123: When the driving unit rotates forward, the second pawl pushes the ratchet wheel to rotate, thereby tightening the brake cable;

[0077] When the drive unit 10 is set to rotate forward, the second pawl 112 pushes the ratchet 81 to rotate; correspondingly, when the ratchet 81 rotates, the direction set by the first pawl 82 can not restrict the rotation of the ratchet 81. At this time, the rotation of the ratchet 81 drives the first winding wheel 5 and the second winding wheel 6 to rotate and tighten the brake cable 2, ultimately achieving the locking function.

[0078] S124: When the driving unit reverses, the transmission plate pushes the first pawl away from the ratchet to release the ratchet.

[0079] Since the second pawl 112 pushes the ratchet 81 to rotate when the drive unit 10 rotates forward, when the drive unit 10 rotates reversely, the second pawl 112 rotates reversely but does not act on the ratchet 81. At this time, the ratchet 81 is fixed in a fixed position by the first pawl 82. Due to the action of the transmission plate 113 on the transmission assembly 11, when the transmission assembly 11 rotates reversely, the transmission plate 113 can act on the first pawl 82 and push the first pawl 82 away from the ratchet 81, thereby releasing the ratchet 81. When the transmission plate 113 rotates and intermittently pushes the first pawl 82 to release the ratchet 81, the ratchet 81 eventually returns to its initial state, driving the first winding wheel 5 and the second winding wheel 6 to rotate and release the brake wire 2, ultimately achieving the unlocking function.

[0080] The vehicle locking or unlocking method provided by this application utilizes the principle that tightening the vehicle brake cable locks the vehicle brake, while loosening it releases the brake. A drive unit drives a set of ratchet assemblies to rotate in different directions, thereby tightening or loosening the brake cable to lock or unlock the vehicle. The method provided by this application has a simple principle and is easy to operate. It can also be used in conjunction with the mobile Internet, making it more convenient for users to use and effectively improving their riding experience.
