[0030] As described in the background section, with the popularization of shared bicycles and electric bicycles, riders have increasingly higher demands for vehicle safety and convenience. Traditional bicycle locks, such as chain locks and U-locks, are mostly external locks that riders need to carry separately. This not only increases the burden of travel but also makes them easy to lose or cause inconvenience during transport. At the same time, these external locks are exposed outside the vehicle and are easily damaged, posing a safety hazard to the vehicle.
[0031] To solve this technical problem, this utility model provides a rotary lock structure.
[0032] For details, please refer to Figures 1-8 The disc brake hub electronic lock specifically includes:
[0033] The spindle 1 and the rotating structure 101 disposed on the outer surface of the spindle 1. Several limiting grooves 105 are provided on the inner wall of one side of the rotating structure 101. An electronic lock located in the rotating structure 101 is also provided on the outer surface of the spindle 1. The electronic lock cooperates with the limiting grooves 105 to lock the rotating structure 101.
[0034] The rotary lock structure provided by this utility model enables electronic unlocking by setting an electronic lock inside the rotary structure 101, eliminating the need for an external lock and providing great convenience for riders. Since the electronic lock is located inside the rotary structure 101, it is well hidden and not easily damaged or discovered, effectively improving the safety of the vehicle.
[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0038] Example 1, please refer to Figures 1-8 A rotary lock structure includes a main shaft 1 and a rotary structure 101 disposed on the outer surface of the main shaft 1. A plurality of limiting grooves 105 are provided on the inner wall of one side of the rotary structure 101. An electronic lock located inside the rotary structure 101 is also provided on the outer surface of the main shaft 1. The electronic lock cooperates with the limiting grooves 105 to lock the rotary structure 101. This application realizes electronic unlocking by setting an electronic lock inside the rotary structure 101, eliminating the need for an external lock and providing great convenience for riders. Since the electronic lock is located inside the rotary structure 101, it is well hidden and not easily damaged or discovered, effectively improving the safety of the vehicle. The rotary structure 101 is a hub.
[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, a first anti-rotation plate 103 is provided on the outer surface of the spindle 1. An end cover 102 is sleeved on the outer surface of the first anti-rotation plate 103 through a bearing. The end cover 102 is connected to the rotating structure 101 by bolts. A bearing is provided between the inner wall of the rotating structure 101 and the outer surface of the spindle 1. A second anti-rotation plate 104 is provided on the outer surface of the rotating structure 101. The second anti-rotation plate 104 is located on the side of the rotating structure 101 away from the end cover 102. The first anti-rotation plate 103 and the second anti-rotation plate 104 cooperate with each other to limit the bearing connected to the rotating structure 101 and the end cover 102, reducing the possibility of the bearing disengaging from the spindle 1.
[0040] Example 2 further optimizes the rotary lock structure provided in Example 1, specifically, as follows: Figure 3 As shown, the electronic lock includes a motor box 204 disposed on the side of the pin bracket 2 away from the first anti-rotation plate 103. A drive component is disposed inside the motor box 204. A sliding block 208 is slidably connected to one side of the motor box 204. A sliding groove 209 is provided on the side of the sliding block 208 near the motor box 204, and the sliding groove 209 is connected to the drive component. The drive component can drive the sliding block 208 to move back and forth to lock and unlock.
[0041] Furthermore, such as Figure 3 and Figure 7As shown, the driving component includes a drive motor 205 and a transmission shaft 206 disposed in a motor housing 204. Both the output shaft of the drive motor 205 and the transmission shaft 206 are provided with bevel gears 207, and the two bevel gears 207 mesh. One end of the transmission shaft 206 extends out of the motor housing 204 and is fixedly connected to a cam 211. A connecting shaft 210 is fixedly installed on the side of the cam 211 away from the transmission shaft 206. The connecting shaft 210 is slidably connected to the inner wall of the slide groove 209. The limiting pin 216 is connected to the motor housing 204 through a bearing. The drive motor 205 can drive the transmission shaft 206 and the cam 211 to rotate through the bevel gears 207. During the rotation of the cam 211, it can drive the connecting shaft 210 to rotate around the transmission shaft 206. The transmission shaft 206 is located at the non-center of the cam 211. During the rotation of the connecting shaft 210 around the transmission shaft 206, it cooperates with the slide groove 209 to drive the sliding block 208 to move.
[0042] Furthermore, such as Figures 6-7 As shown, the sliding block 208 has a receiving cavity 212, and a connecting rod 213 is inserted into the receiving cavity 212. A first spring 214 is provided between the inner wall of the receiving cavity 212 and one end of the connecting rod 213. When the sliding block 208 moves towards the pin bracket 2, the connecting rod 213 and the first spring 214 cooperate to push the limiting pin 216 so that the limiting pin 216 can be inserted into the limiting groove 105.
[0043] Furthermore, such as Figure 6 As shown, a limiting pin 216 is inserted and connected to the pin bracket 2. One end of the limiting pin 216 contacts the end of the connecting rod 213 away from the first spring 214. A second spring 217 is sleeved on the outer surface of the limiting pin 216. The other end of the limiting pin 216 passes through the pin bracket 2 and is inserted into one of the limiting grooves 105. When the sliding block 208 moves away from the pin bracket 2, the connecting rod 213 releases the push on the limiting pin 216, so that the second spring 217 pushes the limiting pin 216 away from the limiting groove 105, so that the limiting pin 216 separates from the limiting groove 105.
[0044] Example 3 further optimizes the rotary lock structure provided in Example 1 or 2, specifically, as follows: Figure 3As shown, a PCB board box 201 is provided between the side of the pin bracket 2 and the top of the motor box 204. The PCB board box 201 is slidably connected to the sliding block 208. A fixing frame 203 is installed between the PCB board box 201 and the side of the motor box 204 away from the pin bracket 2. The fixing frame 203 is connected to the motor box 204 and the PCB board box 201 by bolts. The fixing frame 203 connects the PCB board box 201 and the motor box 204 to the spindle 1, so that the PCB board box 201 and the motor box 204 do not rotate with the spindle 1, and the pin bracket 2 and the spindle 1 do not rotate.
[0045] Furthermore, such as Figure 2 and Figure 3 As shown, a PCB board 219 is provided inside the PCB board box 201. The PCB board 219 is connected to a wire 220. One end of the wire 220 passes through the first anti-rotation plate 103 and extends to the outside of the first anti-rotation plate 103. The wire 220 is used to connect with the vehicle's control system to provide power and control signals.
[0046] Furthermore, such as Figure 6 As shown, the bottom of the PCB circuit board 219 is connected to a third Hall 223 and a fourth Hall 224. The fourth Hall 224 and the third Hall 223 are located on the moving path of the first magnet 215. The fourth Hall 224, the third Hall 223 and the first magnet 215 cooperate with each other to detect the position of the sliding block 208. When the first magnet 215 reaches the third Hall 223, it is in the unlocked state, and when the first magnet 215 reaches the fourth Hall 224, it is in the locked state.
[0047] Furthermore, such as Figure 3 and Figure 6 As shown, the bottom of the slide 209 is also provided with a first Hall 221 and a second Hall 222. The end cover 102 is provided with a number of second magnets 218 on the side close to the first Hall 221 and the second Hall 222. The first Hall 221, the second Hall 222 and the second magnets 218 cooperate with each other to detect the rotation speed of the rotating structure 101 and the end cover 102, thereby realizing the detection of the vehicle speed to confirm whether the vehicle is in motion. The vehicle is not locked during the motion of the vehicle, thereby ensuring the personal safety of the rider.
[0048] The usage process of the rotary lock structure provided by this utility model is as follows:
[0049] When locked, the drive motor 205 drives the cam 211 and the connecting shaft 210 to rotate via the bevel gear 207 and the transmission shaft 206. During the rotation of the connecting shaft 210, it cooperates with the slide groove 209 to drive the sliding block 208 to move towards the pin bracket 2. The sliding block 208 drives the connecting rod 213 and the first spring 214 to move towards the limiting pin 216. If the limiting pin 216 is aligned with the limiting groove 105, the limiting pin 216 is directly inserted into the limiting groove 105. If the limiting pin 216 is not aligned with the limiting groove 105, the vehicle is gently pushed until the limiting pin 216 is aligned. When the limit groove 105 is engaged, the force of the second spring 217 and the first spring 214 pushes the limit pin 216 into the limit groove 105 to achieve locking. When unlocking, the drive motor 205 drives the cam 211 and the connecting shaft 210 to rotate through the bevel gear 207 and the transmission shaft 206. During the rotation of the connecting shaft 210, it cooperates with the slide groove 209 to drive the sliding block 208 to move away from the pin bracket 2. The force of the second spring 217 drives the limit pin 216 to move, so as to separate the limit pin 216 from the limit groove 105, thereby achieving unlocking.
