Description

Lockset and bicycle

Technical Field

Embodiments of the present disclosure relate generally to locksets and to bicycles including the locksets.

Background

Bicycles and other bicycles (such as electric bicycles) are commonly used instead of walk tools, and accordingly, locks of the bicycles are widely used as anti-theft accessories in the bicycles. With the development of the shared bicycle, the requirements on the durability and the reliability of the bicycle lock are higher and higher.

In the traditional lockset, the lock pin can be in direct contact with the side wall of the sliding groove on the lock shell in the sliding process, so that the moving resistance of the lock pin can be increased, and great effort is required for unlocking or locking a vehicle. Furthermore, over time, the latch can wear the side walls of the chute, which can easily cause the latch to become stuck in a damaged area of the side walls. There is a need for improvements in locks to improve the durability and reliability of the lock.

SUMMERY OF THE UTILITY MODEL

The present invention provides an improved lock and bicycle including a lock to address or at least partially address the above or other potential problems.

According to some embodiments of the present disclosure, a lock capable of reducing a movement resistance of a lock pin, improving a life span and reliability of the lock, and a bicycle including the lock are provided. Some exemplary embodiments of a lock and bicycle according to the present disclosure will now be described with reference to fig. 1-4.

According to a first aspect of the present disclosure, a lockset is provided. Generally, the lock includes a lock housing 100, a locking pin 200, and a roller 300, and in some embodiments, the lock may further include communication and control devices and pin actuation components.

As shown in fig. 1-2, the lock housing 100 includes a slide slot 110 and a blind hole 120, wherein the slide slot 110 has a side wall. In some embodiments, the chute 110 can further comprise a bottom wall 111, and wherein the side walls comprise a first side wall 112 and a second side wall 113. The first and

second sidewalls

112 and 113 may extend from both sides of the bottom wall 111 in a direction perpendicular to the plane of the bottom wall 111 in the same direction, respectively, to form the parallel first and

second sidewalls

112 and 113.

The blind holes 120 are arranged at a spacing at the side wall of the chute 110. For example, the blind holes 120 may be provided on both the first sidewall 112 and the second sidewall 113, or the blind holes 120 may be provided only on the first sidewall 112 or the second sidewall 113. As shown in fig. 1 and 2, the first side wall 112 is closer to the outer edge of the lock case 100 than the second side wall 113, and the second side wall 113 is farther from the outer edge of the lock case 100 than the first side wall 112.

In some embodiments, blind holes 120 (e.g., at least two blind holes) may be disposed on the second sidewall 113. Since the user applies a moving force to the lock pin from outside the lock, providing the blind hole 120 on the second sidewall 113 may make it easier for the lock pin 200 to make rolling contact with the rolling member 300 in the blind hole 120.

In some embodiments, the peripheral wall of the blind hole 120 is formed by the respective side wall (e.g., by the first side wall 112 or the second side wall 113), and in the example shown in fig. 2, the peripheral wall of the blind hole 120 is formed by the second side wall 113. In this manner, the manufacturing process of the blind via 120 can be simplified. The peripheral wall of the blind hole 120 may include an opening 121 (shown in fig. 2) facing the chute 110 such that, when the rolling member 300 is mounted in the blind hole 120, a portion of the rolling member 300 protrudes from the second side wall 113 and into the chute 110. Similarly, when the blind hole 120 is formed in the first sidewall 112, a portion of the rolling member 300 protrudes from the first sidewall 112 and extends into the sliding groove 110. With the opening 121 (shown in fig. 1 and 2) on the peripheral wall of the blind hole 120, the rolling member 300 can be brought into rolling contact with the lock pin 200 during the movement of the lock pin.

As shown in fig. 1, the lock pin 200 is adapted to move along the slide groove 110 to switch between a lock position and an unlock position to enter a lock state or an unlock state. In some embodiments, the locking pin 200 may be a C-shaped locking pin to facilitate locking and unlocking of the wheel. Of course, the lock pin 200 may also be a cylindrical lock pin.

As shown in fig. 1, a rolling member 300 is rotatably provided in the blind hole 120, and the rolling member 300 can be brought into rolling contact with the outer peripheral surface 201 of the lock pin 200 when the lock pin 200 moves in the slide groove 110. So, can reduce the friction between the lateral wall of lockpin and spout, reduce the resistance that the lockpin removed and prevent that the lockpin from blocking to improve tool to lock's life and reliability.

In the example in which the blind hole 120 and the rolling member 300 are arranged on the second side wall 113, the lock pin 200 will come into rolling contact with the rolling member 300 without wearing the second side wall 113 while moving. Also, in the example in which the blind hole 120 and the rolling member 300 are disposed on both the first and

second side walls

112 and 113, the movement of the lock pin 200 is further guided, and the lock pin 200 does not wear the first and

second side walls

112 and 113.

In some embodiments, the rolling member 300 is configured as a cylindrical rolling member. Of course, the rolling elements may be conical rolling elements, ball-type rolling elements, etc.

In some embodiments, the rolling member 300 may include a body 301 and a rotation shaft 302 disposed at one end of the body 301, and accordingly, the bottom surface of the blind hole 120 may be further provided with a rotation shaft hole 122. The rotary shaft 302 can be rotatably fitted into the rotary shaft hole 122, so that, with the rotary shaft 302, the rolling member 300 can freely rotate about the axis of the rotary shaft 302.

In this exemplary embodiment, the other end of the rolling member 300 is rotatably engaged by the cover member 130 or with a cover plate for covering the lock case 100, for example, with a corresponding blind hole provided on the cover member 130 or the cover plate. The cover plate here is adapted to be coupled to the lock housing 100 to contain the control and communication equipment, the pin actuation components, etc. within the space formed by the two.

In other embodiments, the rolling members 300 may be provided at both ends thereof with rotation shafts 302, respectively, as shown in fig. 4. The rotary shaft 302 at one end is rotatably fitted into the rotary shaft hole 122 at the bottom surface of the blind hole 120, and the rotary shaft hole 302 at the other end may be fitted into the cover member 130 (e.g., the hole 131 therein) or into a corresponding rotary shaft hole in the cover plate. Thus, with the rotating shafts 302 at both ends, the rolling member 300 can freely rotate about the axis of the rotating shaft 302.

In embodiments having a cover 130, as shown in fig. 3, the cover 130 may also cover the chute 110 to accommodate the locking pin 200 in the chute 110, further guiding the movement of the locking pin 200. The cover 130 may be secured to the lock housing 100 using fasteners through holes 132 in the cover 130 and, finally, the cover plate may be coupled to the lock housing 100 with the cover 130 disposed between the lock housing 100 and the cover plate.

According to a second aspect of the present disclosure, a bicycle is provided. Generally, a bicycle includes a wheel and a lock according to the first aspect of the present disclosure. Wherein the lock pin 200 is configured to prevent rotation of the wheel when moved to the locked position.
