Referring to fig. 1 to 3, an embodiment of the present disclosure provides a brake lock device for a shared bicycle, including:
a brake disc 1 and a lock assembly 2.
The brake disc 1 is provided with locking holes 11, the number of the locking holes 11 can be one, two, three, four or more, the locking holes 11 can be uniformly distributed on the periphery of the brake disc 1, and the brake disc 1 can rotate along with the wheels of a shared bicycle. The lock assembly 2 comprises a driving assembly 21 and a movably arranged first lock bolt 22, the first lock bolt 22 is provided with a first lock section 221 and a first matching section 222, the first lock section 221 is configured to be inserted into the lock hole 11, an inclined side wall 2211 opposite to the rotation direction of the brake disc 1 is formed on the first lock section 221, and the inclined side wall 2211 extends obliquely along the rotation direction of the brake disc 1 from the first matching section 222 to the first lock section 221; the driving assembly 21 comprises a locking spring 211 and an unlocking assembly 212, the locking spring 211 is configured to drive the first bolt 22 to be inserted into the locking hole 11, and the locking spring 211 can increase the locking force of the first bolt 22 to complete the locking operation; the unlocking assembly 212 is configured to drive the first bolt 22 out of the lock hole 11, thereby completing the unlocking operation.
In the state that the brake disc 1 continuously rotates, the first locking section 221 can be located in the locking hole, but because the first locking section 221 is formed with the inclined side wall 2211 opposite to the rotation direction of the brake disc 1, the edge of the locking hole 11 can still push the inclined side wall 2211 to block the first locking section 221 from being inserted into the locking hole 11, and further, the normal rotation of the shared bicycle wheel is ensured. In addition, due to the arrangement of the inclined sidewall 2211, the position of the first locking section 221 where the inclined sidewall 2211 is arranged necessarily becomes narrow, which reduces the structural strength of the first locking section 221. In order to increase the locking strength of the first locking bolt 22, the first locking section 221 may have a cylinder structure with higher strength, such as a cylinder, a regular polygon prism, and the like, which avoids the failure of locking due to the small locking force or deformation of the first locking section 221, and improves the reliability of locking.
The brake and lock integrated design product of the traditional bicycle has a complex structure, a user is required to send an instruction to an electronic component to control unlocking and locking of the bicycle, and when the user sends a locking and unlocking signal due to misoperation, the risk of misoperation of the bicycle locking and unlocking is increased. Especially, if a user triggers a locking signal during riding, sudden locking operation of the bicycle may cause damage to the bicycle, and more seriously, personal injury of the user. According to the technical scheme of the embodiment of the disclosure, the first locking section 221 is arranged, so that the first locking section 221 can be driven to be inserted into the locking hole 11 under the action of the locking spring 211 to complete locking operation; more importantly, the first locking section 221 is provided with the inclined side wall 2211 extending from the first matching section 222 to the first locking section 221 in an inclined manner along the rotation direction of the brake disc 1, and when the bicycle is in an unlocked state, even if the first locking section 221 enters the locking hole 11, the edge of the locking hole 11 can still push the inclined side wall 2211, so that the normal rotation of the shared bicycle wheel is ensured. The embodiment of the disclosure provides a brake lock device, not only the structure is simpler, has avoided the mistake to close the lock moreover and has brought the loss for bicycle and user, has improved the reliability of switch lock.
Optionally, referring to fig. 1, the lock assembly 2 further comprises a movably arranged second lock bolt 23, the second lock bolt 23 is arranged in parallel with the first lock bolt 22, the second lock bolt 23 is connected with the first lock bolt 22, the second lock bolt 23 has a second locking section 231, and the second locking section 231 is configured to be inserted into the lock hole 11; the length of the second locking section 231 is smaller than the length of the first locking section 221.
Specifically, the length of the second locking segment 231 is smaller than that of the first locking segment 221, so that in the locking process, the first locking segment 221 is firstly inserted into the locking hole 11 to be locked, but since the inclined side wall 2211 extending obliquely is arranged on the first locking segment 221, that is, the area of the first locking segment 221 against the brake disc 1 is small, in order to further enhance the locking effect of the brake lock device, the second locking segment 231 and the first locking segment 221 can be inserted into the locking hole 11 together; in addition, when the lock is unlocked, there is a possibility of being stuck between the second locking section 231 and the lock hole 11, if the driving component 21 directly acts on the second locking section 231, the driving component may be damaged due to excessive transient resistance, for example, when the driving component 21 is a motor, the motor may be burnt due to excessive transient current of the motor. Through the buffering of the first locking section 221, the driving assembly 21 directly acts on the first locking section 221, and the first locking section 221 further drives the second locking section 231 to move, so that the second locking section 231 can be gradually pulled out of the locking hole 11, which not only protects the driving assembly 21, but also prevents the brake lock device from being locked.
Alternatively, referring to fig. 1 and 2, the first locking section 221 has a plate-shaped structure, the second locking section 231 has a cylindrical structure, and the cross-sectional area of the second locking section 231 is larger than that of the first locking section 221.
Since the inclined side wall 2211 is arranged on the first locking section 221, the effect of preventing the lock from being closed by mistake can be achieved, but the structural strength of the first locking section 221 with a sheet structure is low, and when the locking hole 11 is inserted to complete the locking operation, the locking may fail due to the fact that the locking force is small or the first locking section 221 is deformed; the cylindrical second locking section 231 can also be inserted into the locking hole 11 to perform locking operation, and the locking effect can be further enhanced due to the cylindrical high-strength structure, so that the locking reliability is ensured.
Alternatively, referring to fig. 1 and 2, the second locking bolt 23 has a second mating section 232, the second mating section 232 is embedded in the first locking bolt 22, and the second mating section 232 is connected with the first locking bolt 22 through a buffer spring 24; the damping spring 24 is configured to move the first locking bolt 22 relative to the second locking bolt 23 in a direction away from the brake disc 1.
Specifically, when the lock needs to be unlocked, the unlocking assembly 212 can drive the first lock bolt 22 to move out of the lock hole 11, the unlocking assembly 212 is kept at the unlocking position, and the lock closing spring 211 is in a compressed state, so that the unlocking operation is completed; when it is desired to close the lock, the unlocking assembly 212 can release the driving force to the first bolt 22, the first locking section 221 can be driven to be inserted into the locking hole 11 under the action of the locking spring 211, so as to complete the locking operation, however, since the instantaneous restoring force of the locking spring 211 is large, there is a possibility of direct collision damage to the first locking bolt 22 and the brake disc 1, the second fitting section 232 is connected to the first plunger 22 through the buffer spring 24, the buffer spring 24 can make the first lock bolt 22 move relative to the second lock bolt 23 in a direction away from the brake disc 1, namely the elastic force of the buffer spring 24 and the locking spring 211 on the first lock bolt 22 is opposite, therefore, the speed of locking can be reduced, the collision damage of the brake lock device is avoided, and the service life of the brake lock device is prolonged.
Optionally, referring to fig. 1 and fig. 3, a receiving groove 223 is formed in the first latch 22, a flange 2321 is formed on the second mating section 232, the second mating section 232 is embedded in the receiving groove 223, the buffer spring 24 is sleeved on the second mating section 232, and two ends of the buffer spring 24 respectively stop against the flange 2321 and an inner wall of the receiving groove 223.
When the lock is unlocked, the unlocking assembly 212 directly acts on the first lock bolt 22, the first lock bolt 22 gradually moves out of the lock hole 11, the first lock bolt 22 drives the second matching section 232 in the accommodating groove 223 to move in a direction away from the lock hole 11, then the buffer spring 24 can play a role of slowly moving the second matching section 232, and the flange 2321 can ensure the stability of the previous connection between the second matching section 232 and the buffer spring 24; in addition, when the second locking section 231 is locked with the locking hole 11, the driving assembly 21 directly acts on the first locking bolt 22, and the first locking bolt 22 further drives the second locking section 231 and the second matching section 232 to move through the buffering of the buffer spring 24, so that the function of preventing the brake lock device from being locked is achieved.
Alternatively, referring to fig. 1, the unlocking assembly 212 comprises a motor 2121 and a driving cam 2122, the driving cam 2122 is provided with a toggle part 21221, and the driving cam 2122 is connected with the motor 2121; the first lock bolt 22 is provided with a shift part 224; the motor 2121 is configured to drive the driving cam 2122 to rotate to an unlocking position, and the toggle part 21221 pushes the toggle part 224 to move the first lock pin 22 out of the lock hole 11.
The driving cam 2122 can convert the axial output force of the motor 2121 into a locking force in the locking direction of the first lock bolt 22 by driving the motor 2121, specifically, the toggle part 21221 directly pushes the shift part 224 to move the first lock bolt 22 out of the lock hole 11, so that the unlocking rate is controllable, and the operation is simple.
Alternatively, referring to fig. 1, the motor 2121 is configured to drive the driving cam 2122 to rotate to a disengaged position, the driving cam 2122 is disengaged from the first latch 22, and the first latch 22 is configured to move toward the brake disc 1 under the action of the locking spring 211.
The driving cam 2122 can not only convert the axial output force of the motor 2121 into a locking force in the locking direction of the first latch 22 by driving the motor 2121, but also change the connection state between the driving cam 2122 and the first latch 22. Specifically, in the case of unlocking, the driving cam 2122 can rotate to a position where the toggle part 21221 directly pushes the toggle part 224, and in the case of locking, the driving cam 2122 can rotate to a state where it is disengaged from the first lock bolt 22, so that the first lock bolt 22 can be moved toward the brake disc 1 by the action of the locking spring 211, and the locking operation can be easily completed.
Optionally, the lock assembly 2 includes an unlock sensor and a lock-off sensor.
