Description

Switch lock mechanism and tool to lock subassembly and vehicle

Technical Field

The invention belongs to the technical field of locks, and particularly relates to a switch lock mechanism, a lock assembly and a vehicle.

Background

In recent years, with the development of the shared bicycle market, the related art of the lock structure has also been further developed and improved. In existing public bicycles or shared bicycles, horseshoe locks are generally used for rotationally locking wheels. When the user uses the bicycle, the horseshoe-shaped lock is operated to finish unlocking or locking actions.

However, such locks have some drawbacks in practical applications. Firstly, when a user uses the vehicle, the user needs to operate the lock, for example, pulling the handle to unlock or close the lock, so that the requirement of operation action is added to the user. Especially, if the user forgets to manually close the lock under the condition that the user is required to manually close the lock to finish the charging, the user is troublesome to finish the charging. Secondly, the switch lock handle on the lock is exposed, and a handle chute is often matched with the lock shell. The sliding groove is easy to fall into foreign matters, is influenced by rainwater and soil, further influences the smoothness of the opening and closing actions of the lockset, and even enables the lockset to be unable to normally open and close the lockset.

On the other hand, with the rapid development of network technology and informatization technology, for public bicycles and other facilities requiring the application of locks, it has become a technical development trend to have a function of automatically executing or automatically detecting the action of the switch lock. In this case, how to improve the accuracy of identifying the opening and closing actions of the lock and how to enable the user to use the facility more conveniently becomes an improvement subject of the lock by those skilled in the art.

In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of exemplary embodiments may have different values.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

The invention provides an improved switch lock mechanism which comprises a lock tongue pushing block, an elastic piece, a lock pin, a guide rail and a driving device. The lock pin is used for locking and locking a component matched with the switch lock mechanism, and the lock pin is movably arranged on the lock tongue pushing block. The lock pin has a pin end that can slide over the deadbolt slider such that the pin end extends outwardly from the edge of the deadbolt slider or retracts inwardly a distance. The elastic piece is arranged on the dead bolt pushing block and is used for applying acting force to the lock pin, so that the pin end of the lock pin can extend outwards from the dead bolt pushing block, namely, the pin end extends and moves in a direction away from the dead bolt pushing block.

Further, the bolt pushing block is arranged in the guide rail in a movable mode. The guide rail is positioned in the switch lock mechanism, can be formed by enclosing a shell, and can also be formed by ribs and grooves arranged on the surface of the structure, and the invention is not limited to the ribs and the grooves. The guide rail is used for guiding the sliding direction of the bolt sliding block. The driving device is used for providing a sliding driving force for the bolt pushing block and driving the bolt pushing block to move in the track.

Through the structural design, under the drive of the driving device, the integral structure formed by the lock tongue pushing block and the lock pin can integrally move relative to the switch lock mechanism. When the driving device pushes the bolt push block and the lock pin to the unlocking position, the lock pin can release the locked mechanism to realize unlocking. When the driving device pushes the bolt pushing block and the lock pin to the locking position, the lock pin can be inserted into the locked mechanism, so that locking is realized. In particular, if the relative positions of the mechanism to be locked and the switch lock mechanism are not in a relatively lockable position when the deadbolt pusher is moved to the lock-off position, the deadbolt end of the lock pin is caused to abut against other surfaces of the mechanism to be locked. At this time, since the elastic member is provided on the tongue pushing block, if the surface of the mechanism to be locked presses the end of the latch, the latch can be retracted a certain distance into the tongue pushing block. When the mechanism to be locked and the switch lock mechanism relatively move to the position capable of being relatively locked, the bolt end of the lock pin can be automatically inserted into the bolt hole of the mechanism to be locked under the action of the elastic piece, so that the locking and unlocking actions are completed.

Further, a limiting part is further formed in the switch lock mechanism, and the limiting part limits the moving stroke of the lock tongue pushing block in the guide rail, so that when the lock tongue pushing block moves to a locking position or an unlocking position under the pushing of the driving device, the limiting part can prevent the lock tongue pushing block from continuously moving. The design mode can accurately stop the bolt pushing block at the unlocking or locking position on one hand, and improves the unlocking and locking action execution accuracy of the unlocking and locking mechanism; on the other hand, the lock tongue pushing block stops moving and the driving device is reversely prevented from moving, and then the generated electric signal change can be used for judging whether the lock tongue pushing block reaches a preset position or not, so that the accuracy of automatically identifying the opening and closing actions of the opening and closing mechanism is improved. The invention does not limit the bolt pushing block to be stopped by the limiting part and prevent further movement when moving to the locking position and the unlocking position. The switch lock mechanism may be configured to block and limit one of the locked position or the unlocked position by the limit portion only, and the other position may be limited by the stroke of the drive device or other structure.

Fig. 1 shows a structure of a switch lock mechanism according to an embodiment of the present invention. The switch lock mechanism further comprises a housing 4, wherein the housing 4 is used for bearing the components. The driving means may include a motor 51 and a cam shaft 52, the cam shaft 52 being provided on a rotation output shaft of the motor 51, which is rotatable by the motor 51. As shown in fig. 6, a groove 12 is formed on one side surface of the tongue pushing block 1, and a cam shaft 52 is inserted into the groove 12. The groove 12 is used for being matched with the cam shaft 52, and under the further matching action of the guide rail 41, the rotation action of the cam shaft 52 can be converted into linear motion, so that the bolt pushing block 1 is driven to move in the guide rail 41. The width of the groove 12 is equal to or larger than the diameter of the cam shaft 52, and is preferably smaller than twice the diameter of the cam shaft 52, so that the cam shaft 52 can smoothly push the tongue pushing block 1 to move in the groove 12.

In the preferred embodiment, the cam shaft 52 rotates in one direction as the motor 51 drives the deadbolt pushers from the closed position to the open position; when the lock tongue pushing block is driven to move from the unlocking position to the locking position, the cam shaft 52 rotates in the opposite direction until the lock tongue pushing block moves to the locking position and cannot move continuously. The length of the groove 12 along the up-down direction in fig. 6 is smaller than the diameter of the cam where the cam shaft 52 is located, and the cam shaft 52 does not rotate by 180 degrees along one direction during the whole driving process. The design mode is convenient for triggering the cam shaft 52 and the motor 51 to be prevented from rotating through the phenomenon that the bolt pushing block 1 is limited and stopped, and triggering the unlocking and locking in-place signals. The invention is not so limited. In other embodiments, the length of the groove may be designed to be equal to or greater than the diameter of the cam on which the camshaft is located, providing sufficient space for the camshaft to rotate 180 in one direction.

The invention provides an alternative embodiment for the structure of the bolt pushing block. The lock tongue pushing block is provided with an arc-shaped groove for placing the lock pin, and the arc-shaped groove is not a closed cylindrical hole but an open structure so that the lock pin can be conveniently placed in the arc-shaped groove. A semicircular notch is formed on the bolt pushing block at one end of the arc-shaped groove, and a round hole 11 is formed at the other end of the arc-shaped groove, as shown in fig. 1. The bolt end 31 of the lock pin 3 extends out of the dead bolt pushing block 1 from the semicircular notch, and the other end of the lock pin 3 far away from the bolt end 31 can be inserted into the round hole 11. By the limitation of the circular hole 11, the lock pin 3 can only move along the axial direction of the circular arc-shaped groove and the circular hole 11, and a good movement guiding effect is formed. Further, the open surface of the circular arc-shaped groove is buckled in the shell or the guide rail 41, so that the lock pin can be further limited in the radial direction, and the lock pin is prevented from moving relative to the lock tongue pushing block except in the axial direction.

Further alternatively, as shown in fig. 1, an annular flange 32 is formed on the lock pin 3, and the elastic member 2 is a spring. The spring can be sleeved on the lock pin 3. One end of the spring is abutted against the annular flange 32, and the other end is abutted against the side wall of the bolt pushing block 1 for forming the round hole 11. In this way, the spring can exert an elastic force on the lock pin 3, pushing the lock pin 3 out of the tongue pushing block 1. In contrast, when the lock pin 3 is pushed out, the annular flange 32 of the lock pin 3 can be abutted against the semicircular notch or can be abutted against the protrusion of the bolt feeding end 31 of the shell 4, so that the position of the lock pin 3 is limited, and the lock pin 3 is prevented from being completely pushed out of the lock tongue pushing block 1 by the elastic piece 2.

Figures 2, 4 and 5 provide an alternative embodiment to the specific configuration of the stop portion employed in the present invention.

The limit portion may include a lock-off limit portion configured to stop the latch pusher 1 when the latch pusher 1 is moved to the lock-off position. Fig. 2 shows the internal structural features of the switch lock mechanism when the deadbolt pusher 1 is moved to the closed position. In the embodiment shown in fig. 2, the inner surface of the side wall of the housing 4 forms the lock stop, and when the lock tongue pushing block 1 moves along the guide rail 41 to a position against the lock stop, the lock tongue pushing block 1 cannot continue to move, and the cam shaft 52 and the motor 51 cannot continue to rotate in a direction to drive the lock tongue pushing block 1 to move to the lock stop. The position where the lock tongue pushing block 1 is stopped by the locking limiting part and stops moving is the locking position.

Similarly, the limit may also include an unlocking limit configured to stop the bolt pusher 1 when the bolt pusher 1 is moved to the unlocking position. Fig. 4 shows the internal structural features of the switch lock mechanism when the bolt pusher 1 is moved to the unlocking position. In the embodiment shown in fig. 2, a blocking wall is formed in the housing 4, and the blocking wall constitutes the unlocking limiting portion. When the lock tongue pushing block 1 moves to a position against the unlocking limiting portion along the guide rail 41, the lock tongue pushing block 1 cannot continue to move, and the cam shaft 52 and the motor 51 cannot continue to move in a direction of driving the lock tongue pushing block 1 to move to the unlocking position. The position of the lock tongue pushing block 1, which is stopped by the unlocking limiting part and stops moving, is the unlocking position.

In the embodiment shown in fig. 2 and 4, the housing 4 of the unlocking mechanism forms an unlocking limit and a locking limit. However, the present invention is not limited to the switch lock mechanism in which the two stopper portions are necessarily formed. In other alternative embodiments, one of the limiting portions may be formed without forming the other limiting portion. The other limit portion may perform limit control by an electric signal such as a rotation angle of the motor 51. Alternatively, a structure for blocking the rotation of the cam shaft 52 may be extended from the motor 51 to block the rotation, thereby achieving the effect of limiting the movement of the latch push block 1.

Optionally, the switch lock mechanism includes a housing 4, and a blocking wall is formed inside the housing 4. Wherein, two opposite retaining walls form the guide rail 41, and a space formed between the two retaining walls is used for accommodating the bolt pushing block and guiding the bolt pushing block to move along the space between the guide rails 41. Alternatively, as shown in fig. 2, 4 and 5, a retaining wall formed inside the housing 4 is provided opposite to the inner surface of the side wall of the housing 4 itself, and the guide rail 41 is formed by combining the retaining wall with the side wall of the housing 4. The invention does not limit the specific forming mode of the guide rail, as long as the guide rail can play a role in guiding movement of the bolt pushing block. Similarly, the present invention is not limited to the manner in which the stopper is formed, and the stopper may be constituted by a baffle wall, a side wall of the housing, and other structures.

Optionally, a circuit board 6 is provided in the switch lock mechanism, and the circuit board 6 may be fixed in the housing 4. As shown in fig. 1 and 2, the circuit board 6 may be integrated with a control circuit of the switch lock mechanism, a driving circuit for driving the motor 51 to rotate, and the like. When the motor 51 is prevented from rotating so that the current of the drive circuit increases, the control circuit may receive the response and form feedback that the switching lock action is in place.

Further, the invention also provides a lockset assembly which comprises the switch lock mechanism and the matching mechanism. The matching mechanism and the switch lock mechanism can move relatively, and the matching mechanism is provided with a lock bolt hole. The switch lock mechanism and the matching mechanism can move relatively and can be in a moving mode of being far away from or close to each other; or the two can rotate relatively; or one may spin and the other may be relatively fixed. The invention does not limit the relative movement between the mating mechanism and the switch lock mechanism.

When the deadbolt pusher 1 is moved to the closed position, the plug end 31 of the lock pin 3 can be inserted into the plug hole 70 of the mating mechanism. In particular, when the cooperating means and the switching lock means are moved relatively so that the bolt hole 70 thereon is not aligned with the bolt end 31 of the locking pin 3, said bolt end 31 can abut against the surface of the cooperating means under the action of the above-mentioned elastic member 2. Once the mating mechanism is moved to a position where the latch bolt aperture 70 is aligned with the latch bolt end 31, the latch bolt end 31 can be automatically inserted into the latch bolt aperture 70 to complete the latch locking action. After the latch end 31 is inserted into the latch hole 70, the relative movement between the mating mechanism and the switch lock mechanism is limited to lock, and the mating mechanism and the switch lock mechanism cannot move relatively. The lock assembly can be applied to facilities such as access control, bicycles, electric vehicles and the like, and the invention is not limited to the facilities.

Further, the invention also provides a vehicle which comprises the lock assembly, a frame and wheels. The wheels are rotatably arranged on the frame and used for bearing the movement of the frame. Typically, the wheels are connected to the frame by a rotating shaft, and rotate about the rotating shaft. In particular, a lock plate is also provided on the wheel, which acts as a mating mechanism in the lock assembly, with a latch aperture provided thereon. The lock disc and the wheels are coaxially arranged on the frame, and when the vehicle moves and the wheels rotate, the lock disc can rotate along with the wheels. The locking and unlocking mechanism is fixedly arranged on the frame, and when the wheel and the lock disc rotate to a specific angle position, the lock bolt holes on the lock disc can correspond to the lock pin positions of the locking and unlocking mechanism, so that the lock pins can be inserted into the lock bolt holes, and the rotation movement of the lock disc and the wheel relative to the wheel is blocked.

In particular, when the vehicle needs to be locked, the electronic device can control the locking and unlocking mechanism to enable the bolt pushing block 1 to move to the locking and unlocking position, and further enable the lock pin 3 to extend towards the lock disc. If the wheel and the lock disk are in an angular position that does not allow the latch aperture 70 to correspond in position to the latch 3, the latch end 31 of the latch 3 may bear against the lock disk, and the spring 2 is compressed. When the wheel and the lock plate rotate to enable the lock bolt hole 70 to correspond to the lock pin 3 in position, the lock pin 3 can be sprung into the lock bolt hole 70 by the elastic action of the elastic piece 2, so that the locking action of the lock plate and the wheel is automatically completed. For a user of the vehicle, if the vehicle needs to be locked, the locking bolt pushing block is only controlled to move to the locking position. The user does not need to operate or confirm whether the plug end has been inserted into the latch bore 70. When the vehicle is moved and the wheel rotates, the lock plate must rotate to a position corresponding to the lock pin 3 and the bolt hole, so that the bolt end is inserted into the lock pin hole to complete the substantial locking of the vehicle.

This kind of structural design provides the convenience for the user to take the operation mode of sharing bicycle as an example: the user can directly operate the unlocking and locking actions of the vehicle on the mobile phone. When an unlocking signal is sent out by mobile phone software, the driving device drives the bolt pushing block to move to an unlocking position to unlock; when the mobile phone software sends out a locking signal, the driving device drives the lock tongue push block to move to the locking position to realize locking action, and the bolt end of the lock pin can be directly inserted into the bolt hole, or under the action of the elastic piece, the lock pin hole is inserted into the bolt hole after rotating to the corresponding position. The user does not need to manually pull the lock handle, and also does not need to confirm whether the vehicle is locked.

The invention has the other advantage that the lock tongue pushing block can not move continuously due to the obstruction of the limiting part when moving to the locking position or the unlocking position, so that the driving device is prevented from moving continuously. The driving device can cause internal driving current to rise after being blocked, and the switch lock mechanism can monitor the driving current through the control circuit of the switch lock mechanism, so as to judge whether the lock tongue pushing block moves to the locking position or the locking position. In the embodiment shown in fig. 2 to 5, the bolt pushing block 1 is stopped by the limiting part when moving to the unlocking position and the locking position, so that the driving current can be used as a monitoring signal when the unlocking action and the locking action are completed. In this way, no additional sensor is needed in the switch lock mechanism, and parts in the switch lock mechanism are reduced. The sensor belongs to a fragile electronic device, the use of the sensor is reduced, the action detection reliability of the switch lock mechanism can be improved, and the failure rate is reduced.

Alternatively, as shown in FIG. 1, the lock collar may have a circular base plate 71 and a cylindrical side wall 72. The round bottom plate 71 is coaxial with the rotation axis of the wheel, and the cylindrical side wall 72 is formed at the edge position of the round bottom plate 71. The latch hole 70 is formed in the cylindrical sidewall 72, and the axis of the latch hole 70 is perpendicular to the rotation axis of the wheel. Preferably, as shown in fig. 1, the axis of the latch hole 70 intersects the axis of rotation of the wheel and the round bottom plate 71. A plurality of latch openings 70 may be distributed along the surface of the cylindrical sidewall 72 to allow for easier insertion of the latch end 31 into the latch openings 70. For example, one latch hole 70 is provided on the cylindrical side wall 72 every 45 degrees of rotation with respect to the rotation axis of the circular bottom plate 71. When the latch bolt hole 70 is not rotated to a position corresponding to the latch bolt end 31, the latch bolt end 31 may be pushed against the outer surface of the cylindrical sidewall 72 if the latch bolt pusher 1 is moved to the closed position.

The preferred opening and closing lock action of the lock assembly provided by the invention is as follows:

as shown in fig. 2 and 3, the deadbolt pusher 1 is in the closed position, and the plug end 31 of the lock pin 3 is inserted into the plug hole 70 in the lock plate, and the lock plate cannot rotate.

After the unlocking command is received by the unlocking mechanism, the motor 51 drives the cam shaft 52 to rotate, and drives the bolt pushing block 1 to slide leftwards. When the bolt pusher 1 slides to the position shown in fig. 4, the bolt pusher 1 is in the unlocking position, which is stopped by the unlocking limit, causing the motor 51 to be stopped. The driving current in the control circuit rises, and the control circuit obtains signal feedback of unlocking completion.

After the locking and unlocking mechanism receives a locking and unlocking instruction, the motor 51 drives the cam shaft 52 to reversely rotate, and drives the lock tongue pushing block 1 to slide rightwards. When the tongue push 1 slides to the position shown in fig. 5, the tongue push 1 is in the lock-off position, which is stopped by the lock-off stopper, causing the motor 51 to be stopped. The driving current in the control circuit rises, and the control circuit obtains signal feedback of the locking action completion. At this point, the lock plate does not have a latch hole 70 corresponding to the position of the lock pin 3, and the latch end 31 abuts against the cylindrical sidewall 72 of the lock plate. The tail end of the lock pin 3 penetrates out of the lock bolt pushing block 1 from a round hole 11 of the lock bolt pushing block 1.

When the wheel and the lock disk are rotated such that the position of one latch hole 70 corresponds to the lock pin 3, the latch end 31 is inserted into the latch hole 70 by the elastic member 2, and the lock disk is substantially locked against rotation, as shown in fig. 2. The tail end of the lock pin 3 is retracted into the lock tongue pushing block 1 from the round hole 11.

While certain specific embodiments of the invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
