Description

Lock and vehicle

Technical Field

Embodiments of the present disclosure relate generally to a latch, and more particularly to a latch for a vehicle such as a two-wheeled or three-wheeled vehicle.

Background

Vehicles such as shared bicycles are widely used in daily life, improving convenience of people's lives. The sharing bicycle is usually provided with an intelligent lock, and the intelligent control of the lock is realized by utilizing the intelligent lock. However, the traditional intelligent lock has the technical problem that the lock is unsmooth to unlock or lock. It is desirable to improve the structure of the lock to improve the smoothness of the unlocking or locking process.

SUMMERY OF THE UTILITY MODEL

It is an object of the present invention to provide a lock and a vehicle to solve or eliminate one or more of the above technical problems.

Detailed Description

The principles of the present disclosure will now be described with reference to various exemplary embodiments shown in the drawings. It should be understood that these examples are described merely to enable those skilled in the art to better understand and further implement the present disclosure, and are not intended to limit the scope of the present disclosure in any way. It should be noted that where feasible, similar or identical reference numerals may be used in the figures and that similar or identical reference numerals may indicate similar or identical functions. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the invention described herein.

While the present disclosure below illustrates the concepts of the present disclosure in terms of an intelligent latch for use on a shared bicycle, it should be understood that the vehicle latch could also be used in other two-wheel or three-wheel vehicles, as well as other suitable vehicles.

The lock according to the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, a lockset 1 according to an exemplary embodiment of the present disclosure mainly includes a locking pin 10 and a locking tongue 30. The locking pin 10 is a generally annular member and is provided with a locking groove 12. The locking bolt 30 also includes a spring member for applying a force to the locking bolt.

As shown in fig. 1, the lock 1 is in a locked state, with the locking pin 10 extending across the entire lock opening. A portion of locking bolt 30 extends into slot 12 under the force of the spring to prevent movement of locking pin 10. When the lock is in the unlocked state, as shown in fig. 2, a portion of the deadbolt is withdrawn from the keyway 12 against the force of the spring, thereby releasing the interaction of the deadbolt 30 with the lock pin 10, whereby the lock pin 10 moves under the force of the spring return to retract from the portion of the opening of the lock.

The lock 1 further comprises a drive mechanism 20. The drive mechanism 20 is used to act on the locking bolt to effect unlocking. In some embodiments, the drive mechanism 20 includes a motor, a wheel, and a lever. The power output shaft of the motor is directly or indirectly connected to the runner to drive the runner to rotate. The turning wheel is eccentrically provided with a deflector rod. When the motor rotates, the driving lever is driven to eccentrically rotate, and the driving lever further drives the lock tongue to move, so that unlocking action is realized. Since these structures are not the focus of the present disclosure, the detailed description thereof will be omitted to avoid obscuring the contents of the present disclosure from the transitional description, and the focus will be on the inventive points of the present disclosure.

In the use of the lock 1, the inventor has found that there is a lock that is stuck, for example when the motor of the actuating mechanism 20 rotates in response to an unlock or lock signal, where the deadbolt cannot be actuated by the toggle lever.

A schematic diagram of a locking tongue and its principle of action according to an embodiment of the present disclosure is described below in conjunction with fig. 3-5.

As shown in fig. 3, the locking tongue 30 includes a protrusion 32 and a toggle part 34, and the protrusion 32 can be inserted into or withdrawn from the locking groove 12 to lock or unlock the lock 1. The toggle 34 can be driven by the toggle 22 to disengage the projection 32 from the keyway 12 to unlock the lock 1. In the illustrated embodiment, the toggle 34 further includes a transition 40, the transition 40 being disposed at the beginning of the initial contact of the toggle 22 with the toggle 34 and being shaped to guide the toggle 22 (the toggle see fig. 5).

As shown in fig. 4 and 5, transition 40 is shaped to guide the eccentric movement of toggle lever 22, particularly at the beginning of the initial contact between toggle lever 22 and toggle 34, whereby transition 40 smoothly guides the interaction of the toggle lever with the deadbolt. Compared with a structure without the transition part 40, the moving smoothness of the shift lever 22 can be obviously enhanced, so that the problem that the lock cannot be unlocked or locked due to the dead locking of the shift lever 22 is effectively prevented.

In some embodiments, as shown in fig. 3 and 4, the protrusion 32 and the dial 34 are arranged side-by-side and the dial includes an open slot that defines an active area of the dial 22 and the dial 34. The shape of the opening groove is adopted to conveniently realize the driving of the lock tongue. In addition, because the side-by-side arrangement is adopted, the length of the lock bolt in the unlocking direction can be obviously reduced. Accordingly, the overall size of the lock can be greatly reduced, and the manufacturing cost can be further reduced.

In some embodiments, as shown in fig. 3 and 4, toggle 34 includes a first stop 342 and a second stop 344 spaced apart from each other along the toggle of deadbolt 30, with an open slot defined between first stop 342 and second stop 344. It should be understood that this latch structure is exemplary only. The first baffle and the second baffle can be in various other shapes as long as the open slot of the lock tongue can facilitate the deflector rod to realize the driving function.

In some embodiments, first barrier 342 is an unlocking barrier and is configured to interact with toggle bar 22 to toggle the locking bolt to move in an unlocking direction to disengage projection 32 from keyway 12 during unlocking of lock 1. In this case, the movement of the lock tongue in the unlocking direction can be achieved by means of the first shutter 342.

In some embodiments, the second stop 344 is a lockout stop and is configured to interact with the toggle lever 22 to limit movement of the deadbolt while the lock 1 is in the lockout condition such that the projection 32 remains in the keyway 12. In this case, in the state where the lock is locked, the latch 30 may be maintained in the locked state by the lever 22, and even if the lock is violently hit or knocked by an external force, the lock may not be opened due to the lever 22 maintaining the pressing of the latch 30, which significantly improves the safety of the lock.

In some embodiments, the transition 40 is formed at the entrance of the open slot. For example, in some embodiments, the transition 40 is formed at the entrance of the first baffle 342. In this case, the transition portion 40 can conveniently guide the shift lever 22 to interact with the first blocking plate without interference, so that the lock is prevented from being locked when the lock is unlocked. In some embodiments, the transition 40 is formed at the entrance of the second baffle 344. In this case, the transition portion 40 can conveniently guide the shift lever 22 to interact with the second stop 344 without interference, so that the lock is prevented from being locked.

In some embodiments, the transition 40 is formed in a smooth shape. In this case, smooth contact of the shift lever with the surrounding parts of the open groove can be achieved. Further, in some embodiments, the transition 40 is formed in the shape of a ramp. Such a structure is easy to manufacture. It should be understood that this shape is merely exemplary. Other implementation shapes will occur to those of skill in the art in light of the present disclosure.

In some embodiments, as shown in fig. 3 and 4, first stop 342 is shorter than second stop 344 to allow clearance for rotation of toggle 22 after lock 1 is unlocked. In this case, the repeated unlocking and locking of the lock is achieved with a simple structure without any interference to the lock.

In the embodiment shown in fig. 5, the turntable structure of the drive mechanism 20 is also shown. As shown in the figure, the turntable is provided with a through hole suitable for being coupled with a power output shaft of a motor, and further comprises a deflector rod. The toggle lever is shown schematically at the location marked by reference numeral 22 in the drawings to those skilled in the art, it being understood that this arrangement is merely exemplary and that the toggle lever may be located in other rotational positions. In some embodiments, the stem is cylindrical. It should be understood by those skilled in the art that the toggle lever may be other suitable shapes.

According to another aspect of the present disclosure, there is also provided a vehicle comprising a lock according to the present disclosure. The vehicle has the advantages of the front fork device. A detailed description thereof will be omitted to avoid redundancy.

Those skilled in the art will understand that: the foregoing description is provided for the purpose of illustration and not limitation. It will be apparent to one skilled in the art that the present invention may be practiced in other implementations that depart from these specific details. Furthermore, unnecessary detail of known functions and structures may be omitted from the current description so as not to obscure the present invention.

Although specific embodiments have been illustrated and described herein, those of ordinary skill in the art appreciate that any arrangement which is calculated to achieve the same purpose may be substituted for the specific embodiments shown and that the invention has other applications in other environments. This application is intended to cover any adaptations or variations of the present invention. The following claims should in no way be construed to limit the scope of the invention to the specific embodiments described herein.
