Description

A switching mechanism and tool to lock and vehicle for tool to lock

Technical Field

The invention belongs to the technical field of locks of public rental vehicles, and particularly relates to a switch mechanism for a lock, the lock and a vehicle.

Background

In recent years, in order to solve the traffic problems such as the last kilometer, the technologies of bicycles, electric vehicles, balance cars and the like have been rapidly developed. Accordingly, how to protect the safety of these vehicles also becomes a technical problem to be solved. In particular, the safety problem of vehicles is particularly prominent in the field of public rental such as shared bicycles.

The state of the art is that public rental vehicles are equipped with locks that cannot be used at will in the normal parked state. The user can use the vehicle by opening the lock of the vehicle through a special procedure and/or a payment program according to the stipulations of the lessor.

Particularly, with the development of public rental vehicles, in order to improve the convenience of use, prevent the vehicle from being stolen, and the like, the locks of the vehicles start to adopt electronic intelligent locks, and automatic unlocking can be realized through software cooperation of the user terminals. This design does solve the above problems, but also brings about new technical problems. For example, the unlocking action reliability of the intelligent lock is low, and phenomena that the intelligent lock cannot be automatically unlocked or the lock cannot be closed frequently occur. This technical problem may be caused by communication obstacles on the one hand and by malfunctions of the automatic unlocking mechanism in the lock on the other hand. When the operation action of the automatic unlocking mechanism is abnormal, the locking and unlocking action of the intelligent lock can not be normally performed very easily.

Therefore, there is a need for an improved lock structure to improve the reliability of the lock for unlocking and locking.

The invention provides a switch mechanism for a lockset, which can be matched with a lockset structure so as to realize the control of the unlocking action of the lockset. The switch mechanism comprises a bolt 1, a cam 2 and a positioning sensor 3, as shown in fig. 1. The lock tongue 1 is used for being in direct or indirect contact with a locking part of a lock, and plays roles in positioning and controlling the locking part. As shown in fig. 2, the latch bolt 1 has a shift portion 111. The cam 2 has a protrusion 21 and a toggle portion 22 extending from the cam 2, as shown in fig. 3. When the cam 2 rotates to a specific position, the toggle part 22 can push the toggle part 22, so that the lock bolt 1 moves to an unlocking position. Further, when the cam 2 rotates to the emptying angle region, the toggle part 22 is disengaged from the toggle part 111. The toggle part 22 does not apply any pushing force to the toggle part 111 and the bolt 1, and the switch mechanism completes one unlocking action. At this time, the protrusion 21 of the cam 2 can trigger the position sensor 3, indicating that one unlocking operation is completed. That is, the position sensor 3 is configured to detect whether the lock tongue 1 completes one unlocking action. Optionally, the lock tongue 1 may be embodied with a driving hole 11, and the shift portion 111 occupies a partial edge area of the driving hole 11. The toggle part 22 can extend into the driving hole 11, and the driving or the clamping of the bolt 1 is realized by propping against the edge of the driving hole 11.

The invention pushes the lock tongue through the toggle part on the cam, and triggers the positioning sensor through the cam after the unlocking action is finished. The whole action is completed by the rotation of the cam, and the reliability and the stability are improved. If the positioning sensor is triggered, the switching mechanism is indicated to complete one switching action. The switching mechanism provided by the invention can effectively improve the reliability of automatic opening of the Zhu-Neng lock.

The action of the cam to drive the movement of the deadbolt is described in connection with the embodiments shown in fig. 4-9. First, as shown in fig. 4, the cam 2 can be in the locking angular position in the emptying angular zone. When the cam 2 is rotated to this position, the dial portion 111 does not contact the dial portion 22. In this position, the cam 2 optionally does not trigger the position sensor, see fig. 5. The present invention does not limit the cam to having to stay in the position shown in fig. 4, but an alternative embodiment of the invention is possible if the cam stays in a position that does not move the bolt to the unlocked position when the lock does not need to be unlocked.

Further, when the unlocking operation is required, the cam starts to rotate. The cam 2 rotates along the rotation direction indicated by the arrow in fig. 4, so that the toggle part 22 abuts against the toggle part 111, and the lock tongue 1 is driven to move to the unlocking position. When the cam 2 is rotated to this position, the bolt 1 is pushed to the unlocked position by the toggle part 22, as shown in fig. 6. This position is typically the furthest distance to which the dial 22 can move the bolt 1. As shown in fig. 7, in this position, the projection 21 of the cam 2 may not activate the position sensor 3.

Further, the cam 2 continues to rotate in the rotational direction indicated by the arrow in fig. 6, and the cam 2 rotates to the emptying angle region. At this time, the toggle part 22 is separated from the toggle part 111, and the toggle part 22 does not apply a pushing force to the bolt 1 any more, as shown in fig. 8. After the cam 2 has rotated into the emptying angle region, the projection 21 on the cam 2 can trigger the position sensor 3, as shown in fig. 9. The position sensor 3 is configured to detect whether the locking bolt 1 has completed an unlocking action. Since the rotational action of the cam 2 has passed through the entire process described above, it can be determined that the switch mechanism has completed one unlocking action, i.e., the latch 1 has moved to the unlocked position, or moved to the over-unlocked position in the previous action. When the positioning sensor 3 is triggered, it indicates that the lock tongue 1 completes the unlocking action.

The unlocking mechanism provided by the invention has good unlocking reliability, and the whole unlocking action is realized by matching a simple cam structure with the shifting part of the lock tongue. And moreover, the in-place detection is realized by triggering the positioning sensor through the cam, so that the unlocking action is ensured to be completed.

Preferably, the switch mechanism provided by the invention can also improve the reliability of the locking action, and can fix the bolt at the locking position. The locking bolt 1 is shown in fig. 6 in the unlocked position and the locking bolt 1 is shown in fig. 4 in the locked position. The cam 2 is configured to be further rotatable to a locking angle when the locking bolt 1 is moved from the unlocked position to the locked position. Referring to the rotation direction shown in fig. 8, when the bolt 1 moves to the locking position, the cam 2 can rotate back to the position shown in fig. 4, and the angular position to which the cam 2 rotates is the locking angle. At this time, the toggle part 22 is located at the lowest position of the driving hole 11, and the latch is located at the locking position. If an external force tries to move the latch bolt upwards to move out of the locking position, the toggle part 22 will abut against the driving hole 11 to prevent the latch bolt from moving out of the locking position. In a preferred embodiment, the above-described configuration of the switch mechanism enables the restraining action of the latch and the lock to be effectively achieved. When the lockset is locked, the lock tongue can return to the locking position to lock the lockset. Furthermore, the cam rotates to a locking angle, and the position of the lock tongue is limited.

In the embodiment shown in fig. 4, the latch bolt 1 has a driving hole 11, and the above-mentioned function of limiting the position of the latch bolt 1 can be realized by the cooperation between the toggle part 22 and the driving hole 11. However, the present invention is not limited to the necessity of having a drive hole in the deadbolt. In other embodiments, the latch bolt may not have a driving hole, but may be separately provided with a fixed stop or a stop edge. When the cam rotates to a locking angle, the shifting part can form a stopping effect with a fixed stopping table, a stopping edge and other structures, so that the lock tongue is limited at a locking position.

In particular, in a further preferred embodiment, the switch mechanism may be further configured to detect whether the cam is rotated to the locking angle by a stop trigger of the position sensor. Referring to fig. 9, when the cam 2 rotates to a certain position of the emptying angle region, the protrusion 21 of the cam 2 triggers the position sensor 3. Then, when the latch bolt 1 moves back to the off-lock position, the cam 2 can continue to rotate in the rotational direction shown in fig. 9. The projection 21 is configured to occupy a portion of the arc of the cam 2, so that the projection 21 continues to trigger the position sensor 3 as the cam 2 continues to rotate. In particular, when the cam 2 is rotated to the locking angle, i.e. the angular position shown in fig. 4 and 5, the projection 21 no longer triggers the position sensor 3. That is, the arc of the projection 21 on the cam 2 is configured to extend only from the position where the start of triggering of the position sensor 3 is started to the cam 2 rotated to the locking angle. Thus, the triggering of the position sensor 3 is cancelled. The feature that the trigger is cancelled enables the position sensor 3 to be configured to detect whether the cam 2 has been rotated exactly to the locking angle. If the triggering of the position sensor 3 is cancelled, this indicates that the cam 2 has rotated to the locking angle, i.e. the position shown in fig. 4 and 5. The cam 2 can stop rotating, forming a limit for the bolt 1.

Optionally, the latch bolt 1 may have an off-lock trigger 12 thereon, and accordingly, the switch mechanism may further include an off-lock sensor 4, as shown in fig. 1 and 4. When the bolt 1 moves to the locking position, the locking trigger part 12 can trigger the locking sensor 4. To indicate that the deadbolt has been in the locked position. In the embodiment shown in fig. 1 and 4, the locking trigger 12 may be a tab extending from the locking bolt 1, and the locking sensor 4 may have a button thereon. In the event that the bolt 1 falls back down to the off-lock position, the tab will press on the button, triggering the off-lock sensor 4. This trigger signal can be used to trigger the rotation of the cam 2 to the locking angle. The present invention is not limited to the configuration of the tab as the closure triggering portion, and in other embodiments, closure triggering portions of other shapes and configurations may be used.

Preferably, the locking tongue may be configured to be automatically movable to the locking position. As shown in fig. 2, a spring 13 or other elastic member may be connected to the latch bolt 1. The spring 13 is configured to apply a force to the bolt 1 moving towards the closed position. When the bolt 1 needs to be moved to the unlocking position, the cam 2 and the striking part 22 need to overcome the force of the spring 13. When the toggle part 22 is separated from the toggle part 111, the cam 2 rotates to the emptying angle area, and the bolt 1 is automatically moved to the locking position under the action of the spring 13. Alternatively, the bolt 1 can be returned to the closed position by the spring 13 when the lock is returned to the closed position. The configuration of the invention improves the automation degree of the switch mechanism, and does not need to be provided with an additional mechanism for controlling the lock tongue to return to the locking position.

Alternatively, the positioning sensor 3 may have a sensor button 31 and an auxiliary pressing member 32 thereon, as shown in fig. 1 and 5. The assist presser 32 is located at a position between the cam 2 and the sensor button 31. When the cam 2 is rotated to a position where the projection 21 triggers the position sensor 3, the projection 21 can contact and ride over the auxiliary presser 32. The protrusion 21 drives the auxiliary pressing member 32 to press against the sensing button 31, so as to trigger the positioning sensor 3. The auxiliary pressing member 32 can convert the rotating force of the cam 2 into the force for pressing the sensor button 31, and reduce the friction and abrasion of the sensor button 31. The reliability and the fluency of triggering the positioning sensor are improved.

From the above description of the activation and deactivation of the position sensor in the preferred embodiment, it can be seen that the activation and deactivation are used to detect whether the switch mechanism has completed the unlocking action and whether the cam has rotated to the locking angle, respectively. Therefore, the protrusion triggering the position sensor when the cam is rotated to which angle is also related to the reliability of the switch mechanism. Referring to fig. 4, the maximum extent of the vent angle region is that the cam 2 rotates the dial 22 counterclockwise from 12 o 'clock to 3 o' clock. Accordingly, for the position at which the position sensor 3 is activated, the maximum range may be that the cam 2 rotates the toggle portion 22 counterclockwise from 12 o 'clock to 6 o' clock. Within this range of rotation angles, the position sensor 3 can be continuously activated. Preferably, referring to fig. 4, the cam 2 may be configured such that when the toggle part 22 is rotated counterclockwise to the 11-9 o' clock position, the protrusion 21 starts to trigger the position sensor 3. Therefore, the accuracy of the unlocking action of the lock bolt when the positioning sensor 3 is triggered can be improved. Fig. 8 and 9 show an embodiment where the protrusion 21 triggers the position sensor 3 when the toggle part 22 is rotated to 10 o' clock direction.

Accordingly, when the toggle part 22 is rotated to the 6 o' clock direction, the cam 2 has been rotated to the locking angle, and the protrusion 21 is configured to cancel the trigger to the position sensor 3. Preferably, therefore, the cam 2 rotates 150 degrees in the emptying angle region from 11 o 'clock direction to 6 o' clock direction, and the trigger on the positioning sensor 3 can be continuously formed.

If the trigger position of the projection on the positioning sensor is too late, the reliability of the unlocking and locking operations of the switch mechanism may be affected. Preferably, therefore, said protrusion 21 triggers the position sensor at least when the toggle part 22 is rotated counter clockwise to 7-8 o' clock, see fig. 4. Optionally, the position sensor is triggered at least within 45 degrees of rotation before the dial 22 is rotated to the 6 o' clock direction. In summary, the protrusion 21 is preferably configured to trigger the position sensor 3 when the cam 2 rotates 45-150 degrees in the emptying angle region. The position for canceling the trigger is a position in which the dial portion 22 is rotated to 6 o' clock direction.

Further, the invention also provides a lock, as shown in fig. 10 and 12, which comprises a locking member 6 and the above-mentioned switch mechanism 01. When the locker 6 is in the locking position, the latch bolt 1 of the switching mechanism 01 is configured to be able to be in the off-locking position, thereby restraining the locker 6 in the locking position. And when the locking bolt 1 is moved to the unlocked position, the locking member 6 is configured to be unlocked and moved to the open position. Further, the bolt 1 is configured to be able to return to the closed position when the locking member 6 returns to the locked position again. Alternatively, in the lock, a motor for driving the cam in the switch mechanism 01 to rotate may be provided.

The improved switch mechanism is adopted in the lockset provided by the invention, and the reliability of automatic unlocking of the lockset is higher. The switch mechanism can accurately complete the unlocking action through the matching action of the cam and the lock tongue. After the unlocking action is completed, the positioning sensor is triggered to give a signal that the unlocking action is completed. Further, the switch mechanism of the preferred embodiment also enables the deadbolt to be retained in the off-lock position when the locking member 6 is in the locked position. Thereby locking the locking member 6 and preventing the locking member 6 from being removed from the locking position.

Alternatively, the lock may include a lock body housing 5 and a buzzer, the lock body housing 5 being configured to house the buzzer, the switch mechanism, and other accessories within the lock. The buzzer is arranged in the lock body shell 5, and a sound emitting area 51 for the buzzer to emit sound is arranged on the lock body shell 5. Fig. 10 shows a back structure of the lock in the embodiment, wherein the sound emitting area 51 can be located on the back of the lock body housing 5. The outside of the sound emitting area 51 communicates with the outside of the lock body case 5, and the inside of the sound emitting area 51 communicates with the internal space of the lock body case 5.

Preferably, as shown in fig. 11, the sound exit region 51 may include an inner layer sound hole 512 and an outer layer sound hole 511. The lock case 5 may have an inner and outer shell wall structure at the sound emitting area 51 so that an inner layer sound hole 512 is formed in the inner shell wall and an outer layer sound hole 511 is formed in the outer shell wall. The outer layer sound hole 511 and the inner layer sound hole 512 are communicated with each other, but the positions of the outer layer sound hole 511 and the inner layer sound hole 512 are shifted from each other as shown in fig. 11. The structural design of the sound emitting area 51 can effectively protect the buzzer, and external foreign matters are difficult to bypass the outer layer sound hole 511 and the inner layer sound hole 512 so as to contact the buzzer. The buzzer is generally not directly damaged. Fig. 11 also shows a specific embodiment of the outer layer sound hole 511 and the inner layer sound hole 512. In this embodiment, the inner sound hole 512 is located at the middle position, and the sound-emitting region 51 has a plurality of outer sound holes 511, and the outer sound holes 511 are distributed in a ring shape to surround the inner sound hole 512 at the center. Each outer acoustic port 511 is not directly opposite the inner acoustic port 512. The structure design can not only provide a good sound transmission path for the buzzer, but also reduce the possibility of damage to the buzzer.

Further optionally, the lock may further include a magnetic anti-slip member thereon. When the locking member is in the open position, there is a risk of the locking member falling back to the locked position abnormally. The anti-slip magnetic component is configured to be capable of fixing the locking component in an adsorption manner when the locking component is located at the opening position, so that the locking component is prevented from slipping back to the locking position. Alternatively, the locking member can be moved from the open position to the locked position only when the magnetic force of the anti-slip magnetic member is contacted or an additional operation is applied.

Fig. 12 is an exploded view of a lock specifically provided by the present invention. In this alternative embodiment, the lock is a horseshoe lock and the locking member 6 is a locking ring. The lock has a slide rail along which the locking ring is configured to be slidable. When the locking ring is slid to the down position, as shown in FIG. 10, the locking ring is in the locked position. When the locking ring moves upwards to leave the whole horseshoe-shaped notch, the locking ring can move to the opening position. Preferably, the anti-slip magnetic component may be disposed beside the slide rail, and the locking ring is provided with a magnetic conductive structure for adsorption. When the locking ring slides to the opening position along the sliding rail, the anti-slip magnetic component can adsorb the magnetic conduction structure on the locking ring.

Alternatively, as shown in fig. 12, the lock may further include a battery 71 and a circuit board 72, and these electric components may also be provided in the lock body case 5. The circuit board 72 can be used for processing signals of electronic devices such as sensors, and the battery 71 is used for supplying power to the circuit board 72, the sensors and the like. In particular, as shown in fig. 12 and 13, the battery 71 and the circuit board 72 may be stacked in the thickness direction of the lock as a whole. The space occupied by the battery 71 and circuit board 72 is reduced, thereby reducing the overall volume of the lock.

The present invention also provides a vehicle, which may be a bicycle, a tricycle, a moped or other vehicle, and the present invention is not particularly limited. The vehicle comprises a vehicle body and the lock. The lockset is arranged on the vehicle body. The lock is configured to lock the vehicle, for example, the vehicle can be locked by locking a wheel, a brake disc, and other components, which is not limited in the present invention.

Although some specific embodiments of the present invention have been described in detail by way of illustration, it should be understood by those skilled in the art that the above illustration is only for the purpose of illustration and is 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.
