Description

Technical Field

[0001] The present invention relates to the technical field of electric-assisted vehicles, and in particular to a battery lock for an electric-assisted vehicle and a method for using the same. Background Art

[0002] An electric-assisted bicycle is a type of transportation vehicle that uses electricity to assist human riding, including bicycles and scooters. It is an important means of transportation in modern life and is widely used.

[0003] The battery is the power source and a key component of electric scooters. Most commercially available batteries are non-removable, being fixed inside the frame or wheel hub. Existing batteries have low capacity, short battery life, and require frequent charging. These electric scooters are not suitable for users, retailers, or couriers who lack access to charging facilities.

[0004] In response to this, electric bicycles with removable batteries have emerged on the market. These batteries can be removed and replaced to meet battery life requirements. These batteries are primarily external, and since they are completely exposed, theft is a common problem. Some industry players install the batteries in the rear rack, top tube, or seat tube of the electric bicycle, locking them with a mechanical locking mechanism to prevent theft.

[0005] However, the mechanical battery lock structure still has certain theft risks, because there is a keyhole exposed to the outside, and criminals may open the battery lock through the exposed keyhole; in addition, the mechanical unlocking method and the user experience are not good, requiring users to use the battery lock key to unlock it, and the battery lock key may be forgotten or lost. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems existing in the prior art that the mechanical battery lock structure can still be stolen and the user experience is poor. An electric bicycle battery lock is proposed to improve the battery anti-theft capability and user experience.

[0007] To achieve the above object, the technical solution of the present invention is: An electric bicycle battery lock, comprising: frame; A lock body, the lock body being rotatably disposed on the frame to lock or unlock the battery; a first reset member, which is disposed in the frame and can automatically reset the lock body; A linkage mechanism is provided on the frame, and can drive the lock body to rotate and lock the battery; The limiting mechanism is arranged on the frame, and the limiting mechanism can limit the position of the lock body so that the battery always remains in a locked state.

[0008] According to one embodiment of the present invention, the linkage mechanism includes a connecting groove, a linkage member and a trigger member, the connecting groove is opened on the lock body, the linkage member can be movably arranged in the connecting groove and can make a linear motion relative to the frame, and the trigger member is arranged on the linkage member and is located on the moving path of the battery.

[0009] Based on the above technical means, when the user installs the battery, when the battery contacts the trigger part, it will drive the trigger part to move a certain distance, and the trigger part will drive the linkage part to move, and then pull the lock body to rotate, so that the lock body automatically locks the battery. The use of automatic locking can reduce the user's operation steps.

[0010] Furthermore, the linkage member is a U-shaped connecting rod, the bent section of the linkage member is located in the connecting groove, the straight section of the linkage member extends outward to the outside of the frame, and the trigger member is arranged at the tail end of the straight section of the linkage member.

[0011] Based on the above technical means, the U-shaped linkage parts can disperse the concentrated load to both sides, reduce local stress concentration, and extend the service life; the U-shaped linkage parts are not easy to detach from the connection groove.

[0012] Furthermore, the linkage mechanism further includes at least one second restoring member, which is sleeved on the linkage member and located at the head end of the straight section of the linkage member.

[0013] Based on the above technical means, the second reset member plays a role of automatic reset. When the battery is removed, the trigger member is not subjected to force, and the second reset member will drive the linkage member to automatically reset.

[0014] Furthermore, a slide groove is provided on the frame, and the linkage member is located in the slide groove.

[0015] Based on the above technical means, the slide groove provides a storage space and movement path for the linkage parts.

[0016] Furthermore, a connecting portion is provided on the trigger member, and the linkage member is located in the connecting portion and is connected via a fastener.

[0017] Based on the above technical means, the triggering member is fixed to the linkage member through the cooperation of the connecting portion and the fastener, thereby ensuring the stability of the connection between the two.

[0018] According to another embodiment of the present invention, the linkage mechanism includes a handle portion, which is disposed on the lock body and extends from the frame.

[0019] Based on the above technical means, the user can manually rotate the handle to drive the lock body to rotate, and then the lock body locks the battery. Using a single handle to drive the lock body to rotate has a simpler structure, is not easy to damage, and has lower production costs.

[0020] Furthermore, the linkage mechanism further includes a limiting portion, which is provided on the lock body and extends from the frame body, and the handle portion and the limiting portion are respectively located inside and outside the frame body.

[0021] Based on the above technical means, the handle part and the limit part are used in conjunction with each other to limit the rotation angle of the lock body to prevent the lock body from rotating at an excessive angle, thereby affecting the locking effect of the lock body.

[0022] Furthermore, the handle portion, the limiting portion and the lock body are an integrated structure.

[0023] Based on the above technical means, the one-piece structure eliminates the weak points of traditional splicing, welding or bolt connections, disperses stress more evenly, significantly enhances impact resistance and deformation resistance, and extends the service life of components.

[0024] Furthermore, the limiting mechanism includes a driving device and a limiting member, the driving device is arranged on the frame and located outside the linkage member and the slide groove, and the limiting member is arranged on the output shaft of the driving device.

[0025] Based on the above technical means, the driving device can drive the limit part to move and then limit the lock body, ensuring that the battery is always locked by the lock body and in a locked state; at the same time, the driving device covers the outside of the linkage part, which can limit the linkage part to ensure that the linkage part can only move in a straight line along a predetermined trajectory.

[0026] Furthermore, the limiting mechanism also includes a mounting box, the mounting box is arranged on the frame, and the driving device is arranged in the mounting box.

[0027] Based on the above technical means, the installation box plays a role in limiting and protecting the driving device, preventing the driving device from being damaged due to environmental factors or human factors.

[0028] According to one embodiment of the present invention, a method for using an electric bicycle battery lock includes locking the battery, inserting the battery into the battery holder, and when the battery contacts the trigger member, the battery is not installed in place. At this time, the battery can continue to move, which can drive the trigger member to move together. The movement of the trigger member will drive the linkage member to move together. The movement of the linkage member will pull the lock body and cause it to rotate, and the lock body will pass through the frame, thereby locking the battery. At the same time, the first reset member is stretched and deformed, and the second reset member is compressed and deformed. The battery is installed in place and the circuit is connected. The user controls the drive device to work through the program, drives the limit member to move toward the lock body, limits the lock body, and keeps the battery in a locked state at all times; and also includes unlocking the battery. The drive device works to drive the limit member away from the lock body and releases the limit of the lock body. At this time, the battery can be pulled out, the first reset member is deformed and drives the lock body to rotate back into the frame, the lock body is automatically reset, the second reset member is deformed and drives the linkage member and the trigger member to return to their positions.

[0029] According to another embodiment of the present invention, a method for using an electric bicycle battery lock includes locking the battery, rotating the handle portion, the handle portion drives the lock body to rotate, so that the lock body enters the frame, and at the same time the first reset member is stretched and deformed to insert the battery into the battery holder. When the battery is installed in place, the handle portion is released, the first reset member is deformed and restored, driving the lock body to rotate, and the lock body passes through the frame, thereby locking the battery. The battery is installed in place and the circuit is connected. The user controls the drive device to work through the program, drives the limit member to move toward the lock body, limits the lock body, and keeps the battery in a locked state at all times; and also includes unlocking the battery. The drive device works to drive the limit member away from the lock body and release the limit of the lock body. The handle portion is rotated, and the handle portion drives the lock body to rotate, so that the lock body enters the frame, and the battery can be pulled out at this time.

[0030] Compared with the prior art, the present invention has the following beneficial effects: The present invention includes a frame, a lock body, a first reset member, a linkage mechanism, and a limit mechanism. The linkage mechanism drives the lock body to rotate, thereby locking the battery. The limit mechanism cooperates with the lock body to limit the lock body, thereby ensuring that the battery lock remains locked. When unlocking is required, the limit mechanism is controlled by a program to release the limit on the lock body, allowing the battery to be unlocked and removed. Compared to traditional mechanical battery lock structures, there is no exposed keyhole, and the battery can only be unlocked with the cooperation of the linkage mechanism and the limit mechanism. This has a higher anti-theft coefficient and a design without a mechanical key, which provides a better user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example 1: like Figure 1-6 As shown, this embodiment provides an electric bicycle battery lock, which is an automatic battery lock and includes a frame 1, a lock body 2, a first reset member 3, a linkage mechanism 4, and a limit mechanism 5. The lock body 2 is rotatably mounted on the frame 1 to lock or unlock the battery 6. The first reset member 3 is disposed between the frame 1 and the lock body 2 and can automatically reset the lock body 2. The linkage mechanism 4 is disposed on the frame 1 and can drive the lock body 2 to rotate and lock the battery 6. The limit mechanism 5 is disposed on the frame 1 and can limit the position of the lock body 2 to keep the battery 6 locked. The linkage mechanism 4 drives the lock body 2 to rotate and lock the battery 6, and the limit mechanism 5 cooperates with the lock body 2 to limit the lock body 2, thereby keeping the battery lock locked. When the battery 6 needs to be unlocked, the limit mechanism 5 is controlled by a program to release the limit on the lock body 2, and the lock body 2 automatically resets under the action of the first reset member 3, thereby unlocking the battery 6.

[0036] Please refer to Figure 1-3, 11 and 12, the frame 1 is a triangular structure as a whole, and can be fixed to the frame 8 by the combination of bolts and nuts or welding. The frame 1 is provided with a notch on one end face close to the battery 6, and the lock body 2 is located in the notch, and when the lock body 2 rotates, a part of it can pass through the notch to lock the battery 6.

[0037] In this embodiment of the present invention, one end of the lock body 2 is rotatably connected to the frame body 1 via a rotating shaft 9, and the rotating shaft 9 is fixedly connected to the lock body 2. In order to make the rotation of the rotating shaft 9 more flexible, a bearing can be provided on the rotating shaft 9.

[0038] In this embodiment of the present invention, the first restoring member 3 is a tension spring. Through holes for installing the tension spring are provided on the frame 1 and the lock body 2. Both ends of the tension spring are connected to the through holes of the frame 1 and the lock body 2 respectively.

[0039] Please refer to Figure 3 and 4 The linkage mechanism 4 includes a connecting groove 401, a linkage member 402 and a trigger member 403. The connecting groove 401 is opened on the lock body 2. The linkage member 402 is arranged in the connecting groove 401 and can move linearly relative to the frame 1. Since the connecting groove 401 is an elongated through groove and the diameter of the linkage member 402 is less than or equal to the width of the connecting groove 401, the linkage member 402 can move in the connecting groove 401. The trigger member 403 is arranged on the linkage member 402. One side of the trigger member 403 protrudes from the frame 1, and this protruding part is located on the moving path of the battery 6. When the battery 6 is inserted into the battery holder 7, the trigger member 403 will contact the battery 6. When the battery 6 continues to move downward, it will drive the trigger member 403 and the linkage member 402 to move together. Since one end of the lock body 2 is connected to the frame 1 through the rotating shaft 9, and it is connected to the linkage member 402 through the connecting groove 401, when the linkage member 402 moves linearly, the linkage member 402 can move in the connecting groove 401, thereby pulling the lock body 2 to rotate, so that the lock body 2 passes through the frame 1 and locks the battery 6.

[0040] In this embodiment of the present invention, the linkage member 402 is a U-shaped connecting rod, the bent section of the linkage member 402 (the bottom of the U-shaped connecting rod is the bent section) is located in the connecting groove 401, the straight section of the linkage member 402 (the two sides of the bent section of the U-shaped connecting rod are straight sections) extends outward to the outside of the frame 1, and the trigger member 403 is arranged at the tail end of the straight section of the linkage member 402.

[0041] Please refer to Figure 5In this embodiment of the present invention, the linkage mechanism 4 further includes a second reset member 404, which functions as an automatic reset member. The second reset member 404 is mounted on the linkage member 402 and located at the beginning of any straight segment of the linkage member 402. In other feasible embodiments, there are two second reset members 404, each mounted on two straight segments of the linkage member 402. The symmetrical arrangement of the two second reset members 404 can balance the load and improve stability.

[0042] In this embodiment of the present invention, the second return member 404 is a tension spring, which is sleeved on the linkage member 402. A gap is left between the frame 1 and the limiting mechanism 5 for the movement of the linkage member 402, and the diameter of the tension spring is larger than the gap. In this way, when the linkage member 402 moves downward, the tension spring will be stuck here and can be compressed, thereby providing power for the return of the linkage member 402 and the trigger member.

[0043] Please refer to Figure 6 Two slide grooves 101 are provided on the frame 1. The two slide grooves 101 correspond to the U-shaped linkage members 402. The linkage members 402 are located in the slide grooves 101. The slide grooves 101 provide a storage space and a fixed path for the linkage members 402.

[0044] Please refer to Figure 6 Two connecting parts 4031 are provided on the trigger member 403, one connecting part 4031 is an open groove 602, and the other connecting part 4031 is a through hole. The two straight sections of the U-shaped linkage member 402 are respectively located in the two connecting parts 4031 and fastened by fasteners 4032.

[0045] In this embodiment of the present invention, fastener 4032 comprises a nut and a bolt. The ends of the two straight sections of linkage member 402 are provided with threads that mate with the nuts, and a threaded hole that mates with the bolt is provided at connection portion 4031. The opening slot 602 connection portion 4031 is tightly fitted with linkage member 402 by the compression of the bolt, while the through-hole connection portion 4031 is tightly fitted with linkage member 402 by the interference of the bolt, thus completing the fastening of trigger member 403 and linkage member 402.

[0046] Please refer to Figure 3The limiting mechanism 5 includes a driving device 501 and a limiting member 502. The driving device 501 is provided on the frame 1 and is located outside the linkage member 402 and the slide slot 101. The limiting member 502 is provided on the output shaft of the driving device 501 and is located on the lower right side of the lock body 2. After the lock body 2 locks the battery 6, the driving device 501 drives the limiting member 502 to move. The limiting member 502 moves to the side of the lock body 2, thereby restricting the lock body 2, ensuring that the battery 6 is always locked by the lock body 2 and remains in the locked state. At the same time, the driving device 501 covers the outside of the linkage member 402 and cooperates with the slide slot 101, so that the linkage member 402 can only move in a straight line, ensuring the movement trajectory of the linkage member 402.

[0047] In this embodiment of the present invention, the driving device 501 is an electric push rod, an air cylinder and an oil cylinder. The driving device 501 is preferably an electric push rod, which is directly driven by electric energy, has high energy conversion efficiency, no energy waste, and does not require compressed air or hydraulic oil.

[0048] Please refer to Figure 1 、 3 4, the limiting mechanism 5 further includes a mounting box 503, which is arranged on the frame 1 and located on one side of the slide groove 101, and the driving device 501 is arranged in the mounting box 503.

[0049] In this embodiment of the present invention, through holes are provided on both sides of the installation box 503, and the frame 1 is also provided with through holes at corresponding positions. The installation box 503 can be fixed to the frame 1 by bolts and nuts, thereby fixing the driving device 501.

[0050] like Figure 3 、 10 -12, a method for using the battery lock of an electric bicycle, including locking the battery 6, when the battery 6 is not assembled in the battery bracket 7, the battery lock state is as follows Figure 3 As shown, the lock body 2 is located in the frame 1, and the limiting member 502 does not interfere with the lock body 2. Insert the battery 6 into the battery holder 7. When the inner wall of the opening slot 602 of the battery 6 contacts the trigger member 403, the battery 6 is not installed in place. At this time, the battery 6 can continue to move downward, which can drive the trigger member 403 to move downward together. The movement of the trigger member 403 will drive the linkage member 402 to move together. The movement of the linkage member 402 will pull the lock body 2 and cause it to rotate. The lock body 2 passes through the frame 1 and partially enters the lock slot 601 of the battery 6, thereby locking the battery 6. At the same time, the first reset member 3 is stretched and deformed, and the second reset member 404 is compressed and deformed. The battery 6 is installed in place and the circuit is connected. The user can control the driving device 501 to work through the program, drive the limiting member 502 to move toward the lock body 2, and move it to the side of the lock body 2 to limit the lock body 2, so that the lock body 2 is always in a locked state. The battery lock state is as shown in FIG. Figure 12A method for using a battery lock for an electric bicycle also includes unlocking the battery 6. The user can control the operation of the driving device 501 through a program, driving the limiting member 502 away from the lock body 2 and releasing the limit of the lock body 2. At this time, the battery 6 can be withdrawn, the first restoring member 3 is deformed and restored, driving the lock body 2 to rotate back into the frame 1, and the lock body 2 automatically returns to its original position. The second restoring member 404 is deformed and restored, driving the linkage member 402 and the trigger member 403 to automatically return to their original positions.

[0051] In this embodiment, there is no need for the user to manually operate the linkage mechanism, and the locking or unlocking of the lock body can be performed automatically, and the linkage mechanism 4 will also automatically return to its original position, thereby improving the user experience.

[0052] Example 2: like Figure 7-9 As shown, this embodiment provides a manual battery lock for an electric assisted bicycle. Compared to Example 1, the main difference lies in the linkage mechanism 4, as well as the structure of the frame 1 and the installation position of the first reset member 3. Specifically, in this embodiment of the present invention, the linkage mechanism 4 includes a handle 405, which is disposed on the lock body 2 and extends from the frame 1. The user can manually rotate the handle 405, causing the lock body 2 to rotate, thereby locking the battery 6. The linkage mechanism 4 also includes a limiter 406, which is disposed on the lock body 2 and extends from the frame 1. The handle 405 and limiter 406 are located inside and outside the frame 1, respectively. The handle 405 and limiter 406 work together. When the lock body 2 rotates to a certain extent, the handle 405 and limiter 406 interfere with the frame 1, thereby limiting the rotation angle of the lock body 2 and preventing the lock body 2 from rotating too far, which would affect the locking effect.

[0053] In this embodiment of the present invention, the first restoring member 3 is a tension spring. Through holes for installing the tension spring are provided on the frame 1 and the handle portion 405 , and both ends of the tension spring are connected to the through holes of the frame 1 and the lock body 2 respectively.

[0054] In this embodiment of the present invention, the handle portion 405 , the limiting portion 406 and the lock body 2 are an integrated structure.

[0055] In this embodiment of the present invention, the handle portion 405 is covered with an anti-slip cover.

[0056] like Figure 9 、 10 , 13 and 14, a method for using an electric bicycle battery lock includes locking the battery 6. When the battery 6 is not assembled in the battery holder 7, the battery lock state is as follows: Figure 9As shown, the lock body 2 partially passes through the frame 1, and the limiting member 502 does not interfere with the lock body 2. The handle portion 405 is rotated, and the handle portion 405 drives the lock body 2 to rotate, so that the lock body 2 enters the frame 1. At the same time, the first reset member 3 is stretched and deformed, inserting the battery 6 into the battery holder 7. When the battery 6 is installed in place, the handle portion 405 is released, the first reset member 3 is deformed again, and drives the lock body 2 to rotate, and the lock body 2 passes through the frame 1, thereby locking the battery 6. The battery 6 is installed in place and the circuit is connected. The user can control the driving device 501 through the program to work, drive the limiting member 502 to move toward the lock body 2, and move it to the side of the lock body 2 to limit the lock body 2, restricting the lock body 2 and keeping the battery 6 in a locked state. It also includes unlocking the battery 6. The user can control the driving device 501 through the program to drive the limiting member 502 away from the lock body 2 and release the limit of the lock body 2. The handle part 405 is rotated, and the handle part 405 drives the lock body 2 to rotate, so that the lock body 2 enters the frame 1. At this time, the battery 6 can be pulled out.

[0057] It should be noted that the present invention can be used not only on electric-powered bicycles, but also on electric-powered scooters. The present invention is also equipped with a control system for the drive device. This control system is based on a combination of wireless communication technology and an intelligent control system. When a user approaches the battery lock (usually within 10 meters) via a mobile phone app, a short-range wireless connection is established via a Bluetooth or NFC module. The mobile phone sends an encrypted command (such as an unlocking key) to the battery lock's receiving module, triggering the drive device 501 to operate and drive the limiter 502 to move, thereby limiting the position of the lock body 2 or releasing the restriction of the lock body 2. Controlling the function of the drive device 501 based on wireless communication technology and an intelligent control system is prior art. The standard parts used in this application can all be purchased from the market, and special-shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be repeated here.

[0058] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
