Abstract

The utility model provides a lockset clutch structure, lockset drive structure, battery lock and electric bicycle, lockset clutch structure includes transmission gear, last stage gear and elastic piece, when last stage gear is in the meshing position, transmission gear drives last stage gear to rotate through gear tooth. When the power supply time of the motor is long and the last-stage gear rotates in place, redundant power of the motor still needs to be released, at the moment, the last-stage gear is located at the critical position, the elastic piece is compressed to accumulate elastic force, the redundant power of the motor drives the transmission gear to rotate to achieve power release, and the last-stage gear cannot continue to rotate along with the transmission gear. And after the power release of the motor is finished, the elastic piece pushes the final-stage gear to return to the meshing area, and the final-stage gear and the transmission gear return to the meshing state. In this way, the transmission gear can still drive the last-stage gear to rotate reversely. By means of the arrangement, it can be guaranteed that the final-stage gear smoothly rotates in place, redundant power of the motor is released, and the problem that the motor is burnt due to repeated rotation blocking is solved.

Description

Technical Field

[0001] This utility model belongs to the field of electric bicycle battery lock technology, specifically relating to a lock clutch structure, a lock drive structure, a battery lock, and an electric bicycle. Background Technology

[0002] Shared electric bicycles have their batteries (such as lead-acid or lithium batteries) located under the seat. When the battery is low and needs to be replaced, the person replacing the battery flips the seat over, lifts the battery from above, inserts a fully charged battery, and then flips the seat back to its original position to complete the battery replacement. To prevent other people from flipping the seat and losing the battery, a battery lock is installed at the seat location, which only the person replacing the battery can unlock. The battery lock works by using a hook to limit the seat's position. When unlocking, the hook rotates to release the limit, allowing the seat to flip. When the seat returns to its original position, it pushes the battery lock hook back to lock automatically. Shared electric bicycles use a mains battery or a small battery electrically connected to the mains battery as a power source to power the locator, central control instrument, battery lock, and other electrical equipment. The battery lock typically uses a motor as the drive component to achieve the locking and unlocking function.

[0003] In real-world usage, the battery voltage is not constant. Depending on the remaining charge, the voltage supplied by the central locking system to the battery lock will also change, fluctuating, for example, between 3.5 and 5.5V. When fully charged, the voltage supplied by the central locking system to the battery lock is higher, resulting in a higher drive motor speed. When the charge is low, the voltage supplied by the central locking system to the battery lock decreases, resulting in a lower drive motor speed.

[0004] The speed of the drive motor and the unlocking speed of the battery lock vary depending on the supply voltage. For example, when the voltage is higher, the drive motor may only need 0.5 seconds to rotate the lock hook to the unlocked position. However, when the voltage is lower, it may take 0.8 seconds for the drive motor to rotate the lock hook to the unlocked position. To ensure that the battery lock can be opened smoothly, the drive motor's operating time needs to be set to the time it takes for the lock hook to rotate to the position at the lowest voltage.

[0005] The drive motor rotates the lock hook via a gear train to transmit power. When the power supply duration of the drive motor varies, the number of rotations of the final gear connected to the lock hook will differ, ultimately resulting in different rotation angles of the lock hook and preventing it from properly opening and closing the lock. If the maximum deflection angle of the lock hook is limited, the excess power output by the drive motor needs to be released; otherwise, repeated stalling and overload will occur, posing a risk of motor burnout. Utility Model Content

[0006] This utility model provides a lock clutch structure, a lock drive structure, a battery lock, and an electric bicycle, aiming to solve the problem that the drive motor on the battery lock of an electric bicycle is prone to stalling and burning out repeatedly during long power supply periods in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] Firstly, this utility model provides a lock engagement / disengagement structure, comprising:

[0009] Transmission gears;

[0010] A final stage gear, wherein teeth are partially provided on the outer periphery of the final stage gear, the final stage gear has an engaging position and a critical position; when in the engaging position, the teeth mesh with the transmission gear; when in the critical position, the teeth disengage from the area meshing with the transmission gear; and

[0011] An elastic element is disposed on one side of the final gear. When the final gear is in the critical position, the elastic element abuts against the final gear and is configured with an elastic force that causes the final gear to rotate from the critical position back to the meshing position.

[0012] In one possible implementation, the elastic element is provided, and the final gear has a first contact portion for abutting against the elastic element, the first contact portion is provided in two parts, and the elastic element is located between the two first contact portions;

[0013] Alternatively, two elastic elements are provided, and the final gear is provided with two second contact portions spaced apart along its own circumference; when the final gear rotates clockwise to the critical position, one of the second contact portions abuts against the corresponding elastic element, and when the final gear rotates counterclockwise to the critical position, the other second contact portion abuts against the corresponding elastic element.

[0014] In one possible implementation, the elastic element is a spring sheet, one end of which is used to connect to the fixing unit, and the other end of which extends to the side of the final gear for abutting against the final gear.

[0015] Compared with the prior art, the beneficial effects of the lock clutch structure provided by this utility model are:

[0016] This utility model provides a lock clutch structure comprising a transmission gear, a final gear, and an elastic element. The final gear is an irregularly shaped wheel, with a portion of it having teeth that mesh with the transmission gear. When the final gear is in the engaged position, the transmission gear rotates, driving the final gear and the lever connected to it to rotate via the teeth. When the motor's power supply time is long, after the lever rotates to its final position, the motor still has excess power that needs to be released. At this time, the transmission gear drives the final gear to rotate to a critical position, the elastic element is compressed and accumulates elastic force, and the final gear disengages from the meshing area with the transmission gear. The excess power from the motor still drives the transmission gear to rotate, but the final gear does not continue to rotate with the transmission gear.

[0017] After the motor's power output ends, the elastic element pushes the final stage gear back to its meshing area with the transmission gear, maintaining the meshing state between the final stage gear and the transmission gear. This ensures that when the transmission gear rotates next time, it can still drive the final stage gear to rotate in the opposite direction. This design ensures that the final stage gear and the shifter rotate smoothly into their positions while releasing excess power from the motor, solving the problem in existing electric bicycle battery locks where the motor is prone to repeated stalling and burnout during extended power supply periods.

[0018] Secondly, this utility model provides a lock driving structure, including:

[0019] The drive unit includes a motor and a transmission mechanism; and

[0020] In a lock clutch structure as described in any of the above implementations, the transmission mechanism is connected to the transmission gear.

[0021] The lock drive structure provided by this utility model includes the above-mentioned lock clutch structure and has the same beneficial effects, which will not be described in detail here.

[0022] Thirdly, this utility model provides a battery lock, comprising:

[0023] Lock case;

[0024] The locking unit includes a lock hook, a locking plate, a lever, and a torsion spring. The lock hook and the locking plate are rotatably disposed on the lock housing, and the lock hook and the locking plate are respectively connected to the torsion spring. The lever is used to push the locking plate to rotate around its own rotation axis.

[0025] A lock drive structure, wherein the lock drive structure is disposed on the lock housing, and the final stage gear is fixedly connected to a rotating shaft, one end of the rotating shaft being rotatably engaged with the lock housing; and

[0026] A lock cover is provided on one side of the lock housing. The lock cover has a clearance hole for the rotating shaft to pass through. The other end of the rotating shaft passes through the lock cover and is connected to the locking unit.

[0027] In one possible implementation, the battery lock further includes an oil seal or a sealing ring, the oil seal or the sealing ring being sleeved on the rotating shaft, and the outer peripheral wall of the oil seal or the sealing ring sealingly engaging with the clearance hole; wherein, the inner wall of the oil seal has at least one lip, the lip being used for sealingly engaging with the rotating shaft, and when the oil seal has multiple lips, the multiple lips are spaced apart along the axial direction of the oil seal.

[0028] In one possible implementation, the battery lock further includes a positioning sleeve disposed in the clearance hole, and the rotating shaft is rotatably engaged with the positioning sleeve.

[0029] In one possible implementation, the lock housing has a structural wall that encloses a receiving cavity, the lock drive structure is housed in the receiving cavity, and a sealing groove is formed on the side of the structural wall adjacent to the lock cover. The sealing groove surrounds the receiving cavity and is used to accommodate sealant.

[0030] The lock cover has a boss on the side adjacent to the lock housing. The boss is arranged along the path of the sealing groove wall and extends into the sealing groove.

[0031] In one possible implementation, the structural wall has a through hole that extends through its own wall thickness, and the lock housing also has a glue-filling cavity formed on the outside of the structural wall. The glue-filling cavity is connected to the through hole and is used to fill with sealant.

[0032] The battery lock provided by this utility model includes a lock shell, a locking unit, a lock drive structure, and a lock cover. The lock shell and lock cover are mated together. The lock drive structure is disposed within the space enclosed by the lock shell and lock cover. A lock hook is used to lock and limit the vehicle seat. The rotating shaft of the lock drive structure extends and connects to a lever. Rotation of the lever can actuate the locking plate, causing the lock hook and locking plate to disengage, completing the unlocking action. After unlocking, the central control unit controls the lock drive structure to reset the lever, and the locking plate resets under the action of a torsion spring. When the vehicle seat flips back to its original position, it can push the lock hook to reconnect with the locking plate, completing the locking action. Furthermore, the battery lock provided by this utility model includes the aforementioned lock drive structure and has the same technical effects, which will not be elaborated further here.

[0047] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0048] Please refer to the following: Figures 1 to 11 The following describes a lock clutch structure, a lock drive structure, a battery lock, and an electric bicycle provided by this utility model.

[0049] Please see Figures 1 to 5 In a first aspect, this utility model provides a lock clutch structure, including a transmission gear 10, a final gear 20, and an elastic element 30. The outer periphery of the final gear 20 is partially provided with teeth 21. The final gear 20 has an engaging position and a critical position. When in the engaging position, the teeth 21 mesh with the transmission gear 10. When in the critical position, the teeth 21 disengage from the area meshing with the transmission gear 10. The elastic element 30 is disposed on one side of the final gear 20. When the final gear 20 is in the critical position, the elastic element 30 abuts against the final gear 20 and is configured with an elastic force that causes the final gear 20 to rotate from the critical position back to the engaging position.

[0050] Compared with the prior art, the beneficial effects of the lock clutch structure provided by this utility model are:

[0051] This utility model provides a lock clutch structure including a transmission gear 10, a final gear 20, and an elastic element 30. The final gear 20 is an irregularly shaped wheel, and a portion of the final gear 20 has teeth 21 that mesh with the transmission gear 10. When the final gear 20 is in the meshing position, the transmission gear 10 rotates, driving the final gear 20 and the paddle 63 connected to the final gear 20 to rotate through the teeth 21. When the power supply time of the motor 41 is long, after the paddle 63 rotates to its position, the motor 41 still has excess power that needs to be released. At this time, the transmission gear 10 drives the final gear 20 to rotate to the critical position, the elastic element 30 is compressed and accumulates elastic force, and the final gear 20 disengages from the meshing area with the transmission gear 10. The excess power of the motor 41 still drives the transmission gear 10 to rotate, but the final gear 20 does not continue to rotate with the transmission gear 10.

[0052] It is understandable that when the last gear 20 rotates to the critical position, since the elastic element 30 is under pressure at this time, the elastic force makes the last gear 20 tend to rotate back to the meshing area. During the rotation, the transmission gear 10 will collide with the teeth 21 of the last gear 20 to produce a grinding sound. This situation will not affect the stable operation of each component.

[0053] After the motor 41 finishes outputting power, the elastic element 30 pushes the final stage gear 20 back to its meshing region with the transmission gear 10, maintaining the meshing state between the final stage gear 20 and the transmission gear 10. This ensures that when the transmission gear 10 rotates next time, it can still drive the final stage gear 20 to rotate in the opposite direction. This design ensures that the final stage gear 20 and the paddle 63 rotate smoothly into their positions, while also releasing excess power from the motor 41, thus solving the problem in existing electric bicycle battery locks where the motor 41 is prone to repeated stalling and burnout during long power supply periods.

[0054] The transmission gear 10 can be a common cylindrical gear, while the final stage gear 20 is an irregularly shaped gear, with teeth 21 partially provided. These teeth 21 mesh with the transmission gear 10. The number of teeth 21 can be three, four, or more, depending on the specific requirements. The shape and structure of the final stage gear 20 can be referenced. Figure 2 and Figure 4 Of course, it can also be other shapes.

[0055] The elastic element 30 is capable of elastic deformation, and its shape can be strip-shaped, plate-shaped, spiral-shaped, or other shapes. One, two, or more elements can be provided as needed. The function of the elastic element 30 is to drive the final stage gear 20 after the excess power from the motor 41 has been released. Figure 4 or Figure 5 The critical position shown is restored to Figure 3 The meshing position is shown.

[0056] In some possible embodiments, one, two, or more elastic elements 30 may be provided. For details, please refer to [link / reference needed]. Figure 1 The elastic element 30 is provided, and the final gear 20 has a first contact portion 22 for abutting against the elastic element 30. There are two first contact portions 22, and the elastic element 30 is located between the two first contact portions 22. When the final gear 20 rotates forward or backward, it can abut against the corresponding elastic element 30, causing it to undergo elastic deformation.

[0057] Alternatively, please see Figures 3 to 5 Two elastic elements 30 are provided, and the final stage gear 20 has two second contact portions 23 spaced apart along its own circumference; when the final stage gear 20 rotates clockwise to the point where Figure 5 At the critical position shown, one of the second contact portions 23 abuts against the corresponding elastic element 30. When the final gear 20 rotates counterclockwise to the position shown... Figure 4 At the critical position shown, another second contact portion 23 abuts against the corresponding elastic element 30.

[0058] Please see Figures 1 to 5In some possible embodiments, the elastic element 30 is a spring sheet, one end of which is used to connect to the fixing unit, namely the lock housing 50, and the other end of which extends to the side of the final gear 20 to abut against it. The spring sheet can be made of materials such as stainless steel or spring steel, and the end of the spring sheet can be fixed by means of bonding, snap-fitting, screw connection, etc.

[0059] Please see Figure 1 , Figure 6 and Figure 10 Secondly, the present invention provides a lock drive structure, including a drive unit 40 and a lock clutch structure in any of the above embodiments. The drive unit 40 includes a motor 41 and a transmission mechanism 42, and the transmission mechanism 42 is connected to the transmission gear 10.

[0060] The transmission mechanism 42 can be an existing power transmission mechanism such as a gear set, linkage mechanism, worm gear mechanism, chain mechanism, etc., which can smoothly transmit the output power of the motor 41 to the transmission gear 10 and drive the transmission gear 10 to rotate.

[0061] Please see Figure 1 , Figures 6 to 11 Thirdly, this utility model provides a battery lock, including a lock housing 50, a locking unit 60, a lock drive structure, and a lock cover 70. The locking unit 60 includes a lock hook 61, a locking plate 62, a lever 63, and a torsion spring 64. The lock hook 61 and the locking plate 62 are rotatably mounted on the lock housing 50, and the lock hook 61 and the locking plate 62 are respectively connected to the torsion spring 64. The lever 63 is used to push the locking plate 62 to rotate around its own rotation axis 24. The lock drive structure is mounted on the lock housing 50, and the final gear 20 is connected to the rotation axis 24. One end of the rotation axis 24 is rotatably engaged with the lock housing 50. The lock cover 70 is mounted on the lock housing 50, and the lock cover 70 has a clearance hole for the rotation axis 24 to pass through. The other end of the rotation axis 24 passes through the lock cover 70 and is connected to the lever 63 of the locking unit 60.

[0062] The battery lock provided by this utility model includes a lock housing 50, a locking unit 60, a lock drive structure, and a lock cover 70. The lock housing 50 can be manufactured by injection molding. The motor 41, transmission mechanism 42, transmission gear 10, and final stage gear 20 are mounted on the lock housing 50. The lock cover 70 is placed on top of it, providing a sealing and protective function. The lock cover 70 and the lock housing 50 can be connected and fixed by means of snap-fit ​​connection, adhesive connection, screw connection, etc.

[0063] The lock housing 50 and lock cover 70 are mated together. The lock drive structure is located within the space enclosed by the lock housing 50 and lock cover 70. Since the lock hook 61 is used to lock and limit the seat, it needs to extend beyond the lock housing 50. To enable the final gear 20 to smoothly drive the locking plate 62 to rotate, the rotating shaft 24 of the final gear 20 extends out of the lock cover 70 and connects to the lever 63. The rotation of the lever 63 can move the locking plate 62, causing the lock hook 61 and the locking plate 62 to disengage, completing the unlocking action. After unlocking, the central control unit controls the lock drive structure to drive the lever 63 to reset. Under the action of the torsion spring 64, the locking plate 62 resets. When the seat flips back to its original position, it can push the lock hook 61 to reconnect with the locking plate 62, completing the locking action. In addition, the battery lock provided by this utility model includes the above-mentioned lock drive structure and has the same technical effect, which will not be described in detail here.

[0064] Considering that electric bicycles may encounter rainy weather during use, to prevent rainwater from entering the lock housing 50 along the rotating shaft 24 and causing damage to the motor 41 or other electronic components, please refer to [link / reference needed]. Figure 7 and Figure 8 In some possible embodiments, the battery lock further includes an oil seal 80 or a sealing ring, which is sleeved on the rotating shaft 24. The outer peripheral wall of the oil seal 80 or the sealing ring seals with the clearance hole, thereby achieving a waterproof seal between the rotating shaft 24 and the clearance hole. The inner wall of the oil seal 80 has at least one lip for sealing with the rotating shaft 24. When the oil seal 80 has multiple lips, the multiple lips are spaced apart along the axial direction of the oil seal 80.

[0065] In this embodiment, the outer peripheral wall of the oil seal 80 is made of rubber. The oil seal 80 is pressed into the clearance hole by a press, and the outer peripheral wall is squeezed to achieve a sealing fit with the hole wall of the clearance hole. The inner wall of the oil seal 80 has one or more lips, which contact the rotating shaft 24 to achieve a seal, thereby preventing rainwater from entering the lock housing 50 along the rotating shaft 24 and causing short circuit damage to the motor 41.

[0066] Please see Figure 7 and Figure 8 In some possible embodiments, the battery lock also includes a positioning sleeve 90, which is disposed in the clearance hole. The rotating shaft 24 is rotatably engaged with the positioning sleeve 90. The positioning sleeve 90 plays an auxiliary positioning role for the rotating shaft 24, which can prevent the rotating shaft 24 from shifting or tilting during rotation, and ensure that the rotating shaft 24 rotates stably around its own axis.

[0067] Please see Figure 6 , Figure 8 and Figure 10In some possible embodiments, the lock housing 50 is provided with a structural wall 51, which encloses and forms a receiving cavity. The lock drive structure is received in the receiving cavity. A sealing groove 511 is provided on the side of the structural wall 51 adjacent to the lock cover 70. The sealing groove 511 surrounds the receiving cavity and is used to receive sealant. A boss 71 is provided on the side of the lock cover 70 adjacent to the lock housing 50. The boss 71 is arranged along the path of the wall of the sealing groove 511 and extends into the sealing groove 511.

[0068] In this embodiment, the boss 71 of the lock cover 70 and the sealing groove 511 of the structural wall 51 form a tortuous channel, and the channel is filled with sealant, which can achieve the sealing of the entire contact surface between the lock cover 70 and the structural wall 51, preventing water vapor from entering and causing damage to the motor 41.

[0069] Please see Figure 6 and Figure 10 In some possible embodiments, the structural wall 51 has a wire passage hole 512 that penetrates its own wall thickness. The lock shell 50 also has a glue-filling cavity 52 formed on the outside of the structural wall 51. The glue-filling cavity 52 is connected to the wire passage hole 512. The glue-filling cavity 52 is used to fill the glue-filling cavity 52. ​​The wire passage hole 512 is used to allow the wires of the motor 41 and other electrical components to pass through. In order to prevent moisture from entering the space enclosed by the structural wall 51 along the wire passage hole 512, after the lock cover 70 and the lock shell 50 are assembled, the glue-filling cavity 52 can be filled with sealant so that the sealant covers the wire passage hole 512, thereby achieving a seal.

[0070] Fourthly, this utility model provides an electric bicycle, including a battery lock as described in any of the above embodiments. The battery lock is mounted on the frame and is used to lock and limit the seat to prevent battery loss.
