Description

Lock and vehicle

Technical Field

Embodiments of the present disclosure relate to a lock and a vehicle.

Background

At present, under the response of a green low-carbon life concept, a shared bicycle becomes a common travel tool for people. Each sharing bicycle is equipped with a lock through which the user can unlock or lock the bicycle. The lockset is a guarantee device for ensuring the functions of vehicle safety, normal operation, use and the like.

In the existing lock device, an end portion of a spring for partially driving the lock ring is easily released from the hooking post, or the spring is easily ejected from the lock ring groove, and in order to prevent the lock from being pried, a high-strength metal lock ring pressing piece is generally used to cover the lock ring groove and the lock ring to play a good role of theft prevention while restricting the movement of the lock ring. However, the above arrangement typically requires a large amount of metal in the manufacturing process, which significantly increases the manufacturing cost, as well as the weight of the bicycle on which the lock is assembled.

SUMMERY OF THE UTILITY MODEL

The inventor has noted that there are some points to be desired in the use of the above known locks. For example, the spring is easily ejected from the locking ring groove, and the manufacturing cost is high because the locking ring pressing piece covering the locking ring groove is integrally made of metal. Moreover, the presence of the locking ring squash made of metal leads to an increase in the overall weight of the bicycle equipped with the lock, thus penalizing the overall handling of the bicycle, in particular of the shared bicycle.

Accordingly, embodiments disclosed herein provide a lock that not only overcomes the above-mentioned drawbacks, but also has the same anti-theft strength as a conventional lock.

According to a first aspect of the present disclosure, there is provided a lock comprising: the lock shell comprises a lock opening and a lock body, wherein the lock opening is used for being sleeved with an object to be locked, and a lock ring groove is formed in the lock shell; a lock ring slidably disposed in the lock ring groove and adapted to move relative to the lock housing to close or open the locking notch; a resilient member slidably disposed in the lock ring groove, the resilient member being coupled between the lock ring and an end of the lock ring groove; a cover body adapted to be coupled to the lock case, the cover body including a stopper portion adapted to be positioned adjacent to a portion of the elastic member not surrounded by the lock ring groove to restrict the elastic member from being disengaged from the lock ring groove when the cover body is coupled to the lock case.

In some embodiments, the lock housing is provided with a boss at the end, the resilient member being coupled to the boss by means of a hook member.

In some embodiments, the cover includes an engagement portion projecting from the cover, the engagement portion having a recess at an end thereof adapted to mate with the projection, the engagement portion adapted to receive at least a portion of the projection when the cover is coupled to the lock housing to limit disengagement of the hook member from the projection.

In some embodiments, the lock includes a locking ring tab at least partially covering the locking ring groove on a side opposite the resilient member.

In some embodiments, the locking ring tab is made of plastic.

In some embodiments, the locking ring impressor is provided with at least one opening.

According to a second embodiment of the present disclosure, there is provided a vehicle including the lock according to the first aspect, a vehicle body, and a wheel, the lock being fixedly provided on the vehicle body, the wheel being rotatably provided on the vehicle body, a lock ring being configured to lock the wheel from rotating.

In some embodiments, the vehicle is a shared bicycle.

By using a structure for pressing against the spring, the spring is further prevented from falling out, the stability of the structure is enhanced, and the plastic lock ring pressing sheet replaces part of the metal pressing sheet and is provided with an opening, so that the weight of the vehicle body is reduced while the manufacturing cost of the lockset is remarkably reduced, and the integral carrying of the shared bicycle is facilitated.

The accompanying drawings are only intended to illustrate embodiments of the present disclosure. Alternative embodiments will become apparent to those skilled in the art from the following description without departing from the spirit and scope of the disclosure.

The present disclosure will be described below by taking a common lock as an example. It should be understood that this is merely exemplary and that the concepts of the present disclosure may be equally applied to other types of locks based on the teachings of the present disclosure. It is to be understood that the directional terminology used in the following description is for the purpose of illustration only and is not intended to be limiting, as the directional terminology may be varied depending upon the particular application.

As shown in fig. 1, a vehicle 100 according to one embodiment of the present disclosure includes: latch 50, body, and wheel. As an example, in certain embodiments, the vehicle 100 may be a shared bicycle. Of course, this is merely exemplary and is not intended to limit the scope of the present disclosure. Any other vehicle now known or developed in the future may use the embodiments described herein. Here, the structures of the vehicle body, wheels, and the like of the vehicle will not be described in detail to avoid obscuring the main aspects of the present disclosure.

As shown in fig. 2, according to an embodiment of the present disclosure, a lock 50 includes: a lock housing 52, a lock ring 54, a resilient member 56, and a cover 58.

The lock housing 52 includes a locking notch 76 for nesting a locked object therein, which in some embodiments may be a spoke on a wheel. The lock 50 limits the rotation of the wheel by limiting the movement of the spokes within the locking notch 76. This is merely exemplary and the rotation of the wheel may be limited in other ways.

A lock ring groove 64 is formed inside the lock case 52, the lock ring 54 is slidably disposed in the lock ring groove 64, and a first portion of the lock ring groove 64 is communicated to a space outside the lock case 52, allowing the lock ring 54 to enter the lock ring groove 64 from an end portion 66 and to protrude from another end portion 68 for locking a locked object. The other end 68 is the section which is arranged opposite the end 66 with respect to the locking notch 76.

The shape of the locking ring and the shape of the locking ring groove are not limited, and the locking ring groove need to be matched so as to realize good movement of the locking ring in the locking ring groove.

In some embodiments, a handle is fixedly disposed on the locking ring 54 at a section proximate the other end 68, the handle adapted to drive movement of the locking ring 54 in response to a force applied to the handle.

In some embodiments, a control module, communication module, or the like may also be disposed within the lock housing 52 for controlling movement of the lock ring 54 within the lock ring slot 64 for closing or opening the lock opening 76. The present application is not intended to limit the types and arrangements of these components.

The resilient member 56 is slidably disposed in a locking ring groove 64 with the locking ring 54, both ends of the resilient member being connected to the locking ring 54 and an end 66 of said locking ring groove 64, respectively, and being stretched in response to the locking ring being available for the locking ring 54 to enter the locking ring groove 64 from the end 66 and to protrude from the other end 68, and being further adapted to bring the locking ring 54 to slide back into the locking ring groove by a restoring force when unlocking. Although the resilient member 56 is shown as a spring in fig. 2, this is merely illustrative and is not intended to limit the scope of the present disclosure, as any other suitable resilient member may be employed.

In one embodiment, as shown in FIG. 2, the resilient member 56 is removably secured to a tab 521 by means of a hook member 561, the tab 521 being disposed at the locking ring portion 66, the tab 521 may be any suitable shape suitable for securing a hook of the resilient member.

As shown in fig. 3, the lock 50 further includes a cover body 58, the cover body 58 being adapted to be coupled to the lock housing 52, the cover body 58 including a stop 581 protruding therefrom at a location opposite the spring in the shackle groove 64. As shown in fig. 4, the stopper 581 is adapted to be positioned adjacent a portion of the resilient member 56 not surrounded by the locking ring groove 64 when the cover body 58 is coupled to the lock case 52 to restrict the resilient member 56 from being disengaged from the locking ring groove 64.

In one embodiment, the stopper 581 is in the shape of a tab, as shown in fig. 3, that may pass through the center of the cross-section of the resilient member 56 to press against or otherwise prevent the resilient member 54 from disengaging from the locking ring groove in a non-contacting manner from the portion of the resilient member not surrounded by the locking ring groove 64.

In one embodiment, as shown in fig. 3, the cover 58 includes an engagement portion 582 protruding from the cover 58, the engagement portion 582 having a concave portion 583 at an end thereof that mates with the convex portion 521, the concave portion 583 having a shape that matches the shape of the convex portion 521.

As illustrated in FIG. 4, the engagement portion 582 is adapted to receive at least a portion of the tab 521 when the cover 58 is coupled to the lock housing 52 to limit disengagement of the hook member 561 from the tab 521 and the resilient member 56 from the lock ring slot 64.

The elastic member 56 is secondarily restrained by the restraining portion 581 and the engaging portion 582 to further prevent the elastic member 56 from being separated from the latch groove, thereby enhancing the structural stability.

Returning to FIG. 2, the lock housing 52 further includes a lock ring tab 60 disposed on an opposite side of the resilient member 56 with respect to the locking notch for at least partially covering the lock ring groove 64 to secure the lock ring 54 within the lock ring groove 64. The locking ring press 60 extends a distance along the other end 68 of the locking ring groove 64 toward the middle of the locking ring groove 64. In some embodiments, the length of the extension of the locking ring impressor 60 that overlies the locking ring slot 64 may be selected as desired.

As shown in fig. 2, the lock ring presser 60 is overlaid on the lock ring groove 64 from the side above the paper surface, thereby preventing the lock ring 54 from coming out of the lock ring groove 64.

In certain embodiments, the lock ring 54 slides within the lock ring slot 64. The locking ring pressing sheet 60 is used for limiting the locking ring 54 and limiting the locking ring 54 in the locking ring groove 64, so that the locking ring cannot shake or loosen along the radial direction of the locking pin.

In one embodiment, the locking ring tab 60 is made of a plastic material, which reduces the weight and cost of the lock while maintaining structural stability and good theft resistance.

In one embodiment, the locking ring impressor 60 is provided with at least one opening 601 for further saving material and weight.

An advantage of the lock according to the present application is that the resilient member 56 is assisted in its position by one or more structures that press against the spring to further prevent the resilient member from disengaging the latch groove, thereby enhancing structural stability. Compared with the prior art, the limiting reliability is stronger, the influence of the assembly error of the lock shell is avoided, the manufacturing cost is reduced, and the weight of the lock is reduced. In addition, the locking ring slides in the locking ring groove, so that the problems of shaking, unsmooth sliding and the like are not easy to occur. Further, set up the opening on the catch preforming, can be on the basis that does not influence structural stability and theftproof nature again, can further save material, reduce the tool to lock cost.
