The utility model provides a switching mechanism for tool to lock, this switching mechanism can cooperate with the tool to lock structure to the realization is opened the control of action to the tool to lock. The switch mechanism comprises a bolt, a driving wheel and a Hall sensor.

The bolt 1 is movably arranged in the lock, and can be moved to a locking position and a releasing position. 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. 1 and 2, the bolt 1 has a fitting portion 11.

As shown in fig. 1 and 3, the driving wheel 2 has a driving portion 21, and the driving wheel 2 is further provided with at least a first magnet 22 and a second magnet 23. The driving wheel 2 can rotate, and the driving part 21 rotates to a position where the matching part 11 can be driven to move through rotation, so that the whole lock tongue 1 is driven to move. The drive wheel 2 is configured to be able to move at least the bolt 1 to the release position by rotating.

As shown in fig. 1 to 5, the first magnet 22 and the second magnet 23 may be distributed along the circumferential direction of the driving wheel 2, and the first magnet 22 and the second magnet 23 may be rotated to the position of triggering the hall sensor 51 by the rotation of the driving wheel 2. The driving part 21 also rotates to a specific position by the rotation of the driving wheel 2 to drive the bolt 1 to move. The positions of the first magnet 22 and the driving portion 21 on the driving wheel 2 may be at the same angular position in the rotation direction of the driving wheel 2. That is, when the driving wheel 2 rotates, the first magnet 22 and the driving portion 21 rotate to the same angular position. The first magnet 22 is then at a different position in the direction of rotation of the drive wheel 2 than the second magnet 23.

The utility model provides an among the switch mechanism, through drive wheel 2's rotation, when drive wheel 2 rotated different positions, first magnet 22 and second magnet 23 can trigger respectively hall sensor 51. The first magnet 22 and the second magnet 23 trigger the hall sensor 51 by the generated magnetic field without making direct contact with the hall sensor 51.

In a state where the latch bolt 1 moves to the lock position, the driving wheel 2 is configured to be rotatable to a position where the second magnet 23 triggers the hall sensor 51, so that the driving part 21 performs a limit function on the latch bolt 1 to prevent the latch bolt 1 from moving to the release position.

The utility model provides a switch locking mechanical system triggers hall sensor through first magnet and second magnet to detect the gesture that the drive wheel rotated, whether the detection switch latch mechanism accomplishes to unblank or closes the lock action. The switch lock mechanism avoids the driving wheel from mechanically triggering the sensor in a contact mode in the rotating process, and avoids the possible abrasion and mechanical faults of the driving wheel and the sensor in practical application. The driving wheel needs to rotate to apply force so as to drive the lock tongue to move. If the drive wheel is simultaneously mechanically contacted by the trigger sensor, there is the possibility that the contact trigger sensor will interfere with the rotation of the drive wheel. In practical application, the cam collides with the contact type trigger sensor due to collision and the like, so that the phenomenon that the sensor is abnormally triggered exists. Further, the collision may damage the structure for touch activation on the sensor, and once the structure is damaged, the sensor may not be normally activated, and the damaged structure may prevent the driving wheel from rotating. And the utility model provides a switch locking mechanical system does not adopt the sensor of contact, but adopts magnet and hall sensor's magnetism to trigger the mode, has avoided above-mentioned defect, has improved switch locking mechanical system's reliability.

As shown in fig. 3, the first magnet 22 and the driving portion 21 are located at the same angular position, and in a state where the first magnet 22 triggers the hall sensor 51, on the one hand, the first magnet can represent that the latch mechanism performs a specific action, and also represents that the driving portion 21 rotates to a position facing the hall sensor 51, that is, the present invention provides a latch mechanism capable of detecting a position where the driving portion 21 rotates.

According to the actual structural characteristics of the switch lock mechanism, when the driving part rotates to the position facing the hall sensor 51, the switch lock mechanism can perform a specific action. For example, in an alternative embodiment, the driving wheel 2 completes the movement of the latch bolt 1 to the release position when the first magnet 22 and the driving part 21 rotate to the direction toward the hall sensor 51.

Through the utility model discloses it is right the position design of first magnet and drive division can make the tool to lock that uses accurate position that detects the drive division, and then judges the action that switch locking mechanical system carried out. The reliability of the action matching of the switch lock mechanism is improved.

The utility model provides a switching lock mechanism moves under the state of locking position at the spring bolt, and the control drive wheel will the drive division rotates to the position of restriction spring bolt to play the effect that prevents the spring bolt and remove to the release position. The effect of preventing the lock tongue from moving to the releasing position accidentally is achieved, and the safety of the locking and unlocking mechanism is improved.

The utility model provides two kinds of messenger the spring bolt removes the embodiment of locking position. Alternatively, as shown in fig. 1, 2 and 5, the switch lock mechanism comprises a spring 13, and the spring 13 can apply a force to the bolt 1 to move to the locking position. The spring 13 will move the bolt 1 to the locking position without an obstacle blocking the bolt 1 from moving to the locking position. In this state, the driving wheel 2 can rotate to a position where the driving part 21 can limit the latch bolt 1. In this embodiment, the spring 13 can continuously apply force to the lock tongue 1, and once objective conditions can make the lock tongue 1 move to the locking position, the lock tongue is immediately moved to the locking position by the spring 13, and the locking reliability is high.

Alternatively, the drive wheel may be controlled to perform a locking action by an external signal. The driving wheel rotates, so that the driving part drives the lock tongue to move to a locking position. The driving wheel rotates to a position where the driving part limits the lock tongue. In this embodiment, the bolt is moved into the locking position directly by the rotation of the drive wheel, without the need to provide further components for the opening and closing mechanism.

Alternatively, as shown in fig. 4 and 5, the position of the first magnet 22 on the driving wheel 2 is designed so that the first magnet 22 can trigger the hall sensor 51 after the driving wheel 2 moves the latch bolt 1 to the release position during the rotation of the driving wheel 2. The first magnet 22 and the driving part 21 are located at the same position in the circumferential direction of the driving wheel 2, and when the driving wheel 2 is rotated to a posture in which the latch bolt 1 is moved to the release position by the driving part 21, the first magnet 22 is also rotated to the same position. Thereafter, the driving wheel 2, which has completed the control operation of moving the latch 1 to the release position, further rotates, and the driving portion 21 and the first magnet 22 rotate to the position facing the hall sensor 51. The hall sensor 51 is triggered by the magnetic field of the first magnet. In this embodiment, the triggering of the hall sensor by the first magnet represents the completion of the movement of the deadbolt to the release position by the drive wheel, and the signal generated by the hall sensor being triggered can be used as a condition for the lock to determine whether to unlock. According to the embodiment, whether the driving wheel and the driving part complete one unlocking action or not can be accurately judged through the Hall sensor. Since the driving part is located at the same position as the first magnet, it can be determined that the driving part has rotated to a position corresponding to the hall sensor, and the unlocking action is completed.

Optionally, the first magnet and the second magnet have an angular range limit in position on the drive wheel. For example, the relative angular difference between the first magnet and the second magnet in the rotational direction of the drive wheel ranges from 130 ° to 60 °. In the embodiment shown in fig. 3, the angular difference between the positions of the first magnet 22 and the second magnet 23 in the rotational direction is 90 °. If the angle between the first magnet 22 and the second magnet 23 is too large, for example, exceeds 180 °, the hall sensor 51 needs to be positioned at an angular position that differs greatly from the above-mentioned limit position in the rotational direction of the drive wheel 2, in order for the drive part 21 to be able to rotate to the limit position that limits the latch bolt 1 in the state where the latch bolt 1 is moved to the lock position. This design may not satisfy the functional requirement that the driving wheel 2 completes the movement of the latch bolt 1 to the release position in the state where the hall sensor 51 is triggered by the first magnet 22. The angle difference between the first magnet 22 and the second magnet 23 is controlled within a range of 130 degrees or less, so that the functional diversity of the switch lock mechanism can be improved, and the switch lock mechanism can realize more over-detection and switch lock functions on a limited structure. On the other hand, the reliability of the locking and unlocking mechanism for executing locking and unlocking actions can be improved, the situation that the magnet triggers the Hall sensor only by driving the rotating wheel to rotate by a too large angle in the action executing process is avoided, and the situation that the detection vacuum area is too long is avoided.

If the angle between the first magnet and the second magnet is too small, for example, less than 40 °, more precise positional relationship and assembly relationship between the first magnet, the second magnet, and the projecting portion, the hall sensor are required. In this case, after the driving wheel rotates by a small angle, the first magnet and the second magnet need to trigger the hall sensors respectively, and the assembly among the structures and the structural shape accuracy need to be higher so as to meet the accurate matching after the rotation by a small angle. This design can increase the difficulty of machining and assembling the switch lock mechanism. On the other hand, because the hall sensor is triggered through the magnetic field, if the included angle between the first magnet and the second magnet is too small, the magnetic fields of the first magnet and the second magnet may interfere with each other, and the hall sensor cannot be triggered accurately or abnormally.

The included angle of the first magnet and the second magnet on the driving wheel ranges from 130 degrees to 60 degrees, so that the requirements on the function and the reliability of the locking and unlocking mechanism can be better met.

Optionally, the switching lock mechanism further comprises a switch lock sensor 3. As shown in fig. 1 to 5, the latch bolt 1 is provided with a trigger 12. The trigger 12 can trigger the lock sensor 3 in a state where the tongue 1 is moved to the lock position. The lock sensor 3 may be a mechanical push type or button type switch mechanism, or may be a hall sensor 51. When the latch bolt 1 is moved from the latched position to the released position, the latch sensor 3 is deactivated. The effect of the response of the lock sensor 3 being deactivated may be used as a condition for determining whether the open-close mechanism is open. When the latch bolt 1 moves from the release position to the lock position, the trigger 12 of the latch bolt 1 triggers the lock sensor 3. The effect of the response of the lock sensor 3 being triggered can be used as a condition for determining whether the lock mechanism is locked. If the locking sensor 3 is a mechanical sensor, the trigger 12 may be a protrusion for pressing the sensor. If the locking sensor 3 is an optical sensor or a hall sensor 51, the trigger 12 may be a sheet structure or a magnet for blocking an optical path.

Through the design of the locking sensor and the trigger part, whether the lock tongue moves to the locking position or not can be detected, and therefore the detection reliability of locking is improved.

Optionally, the trigger part has an inclined surface 122 inclined forward and upward with respect to the moving direction of the latch, and a trigger surface 121 extending downward from the front end of the inclined surface 122. The moving direction of the latch bolt refers to a direction moving from the lock position to the release position or a direction moving from the release position to the lock position. In the embodiment shown in fig. 4 and 5, the sensor is a lock-off sensor, and the inclined surface 122 may extend forward and obliquely upward along the direction in which the latch bolt moves from the release position to the lock position. In another embodiment, an unlocking sensor may be provided, and the inclined surface 122 may extend forward and obliquely upward along the direction in which the lock tongue moves from the locking position to the releasing position. As shown in fig. 2, the trigger surface 121 extends downward from the highest point of the front end of the inclined surface 122.

Optionally, the structure of the random trigger surface 121 may be adjusted according to the characteristics of the trigger mode, the setting position, and the like of the locking sensor. For example, the trigger surface 121 may extend obliquely downward to form a surface inclined with respect to the moving direction of the latch; or may extend vertically downward to form a surface perpendicular to the direction of movement of the bolt.

In the embodiment shown in fig. 2, the trigger portion formed by the inclined surface 122 and the trigger surface 121 is shaped like a right triangle. In other embodiments, the trigger portion may have a structure similar to a right trapezoid, or a structure of a triangle or a trapezoid. As an embodiment, one side of the triangular structure is used as the trigger surface 121, that is, the side facing the moving direction of the latch bolt is used as the trigger surface 121 for triggering the sensor. The trigger part is simple in structure, high in stability and convenient to process, and is beneficial to reducing the structural complexity of the whole lock tongue, so that the production cost is reduced. The sensor may be a circuit switch which in a triggered state closes the circuit and in a non-triggered state opens the circuit. The on and off of the circuit can be used as a trigger signal.

Optionally, as shown in fig. 2, a hollow area 123 is disposed on the trigger portion. The trigger surface 121 and the inclined surface 122 surround the outer circumference of the hollow area 123. As an embodiment of the present invention, the trigger portion of the transmission member has a flat triangular structure. Offer fretwork area 123 on the flat board, this design can alleviate the weight of driving medium to do benefit to the weight that reduces whole tool to lock, the setting in fretwork area 123 can effectively reduce the inhomogeneous shrink of driving medium in-process of moulding plastics simultaneously, thereby guarantees the size precision of driving medium. Optionally, the shape of the hollow-out area 123 is a triangle similar to the shape formed by the inclined surface 122 and the triggering surface 121. The triangle and the flat triangle are similar triangles. When the transmission part is opened, the center of the hollowed-out area coincides with the center of the tabular triangular structure, and the vertical lines of the two sides coincide.

Optionally, the switch lock mechanism further comprises a bolt pressing plate 111, the bolt pressing plate 111 penetrates through the hollow area 123, and the bolt pressing plate 111 is configured to limit the bolt.

As an embodiment of the present invention, as shown in fig. 6, the switch lock mechanism further includes a latch pressing plate 111. The latch pressing plate 111 functions to restrict the latch to move in a specific direction. Optionally, a slide way in which the bolt slides is arranged in the lock assembled with the slide way, the slide way is provided with an opening side, and the bolt is installed into the slide way from the opening side of the slide way. The bolt pressing plate 111 is used for covering the opening side of the slide way and preventing the bolt from jumping out of the slide way. Optionally, a notch is formed in one side of the latch bolt pressing plate 111. During installation, the triggering portion extends into the gap, so that the related pressure plate passes through the hollow area 123. Thus, the latch bolt pressing plate 111 and the transmission member form a mutually nested limiting relationship. Through the structural design characteristics, the arrangement of the lock tongue pressing plate can effectively prevent the lock tongue from deviating from the sliding direction to move, and the moving reliability of the lock tongue is improved. Meanwhile, the lock catch type connection mode formed between the lock tongue pressing plate and the transmission piece can improve the connection stability of the lock tongue pressing plate.

Alternatively, as shown in fig. 3, the first magnet 22 and/or the second magnet 23 may be embedded inside the driving wheel 2. The driving wheel 2 can be made of plastic materials through a plastic injection molding process. During the machining of the drive wheel 2, the first magnet 22 and/or the second magnet 23 can be arranged in advance in the injection mold. The first magnet 22 and/or the second magnet 23 can be fixedly embedded in the driving wheel 2 by means of an injection molding process, so that the magnets become part of the driving wheel 2. The combination mode can greatly improve the connection reliability of the magnet and the driving wheel and avoid the magnet from falling off from the driving wheel. On the other hand, the driving wheel can also protect the magnet, and the interference of other electromagnetic structures to the magnet is reduced. Alternatively, the end faces of the first and/or second magnets may be exposed from the surface of the drive wheel. The end faces of the magnets may be exposed from the rotating circumferential surface of the drive wheel 2, as shown in fig. 3, for example. Such an embodiment may bring the first magnet 22 and/or the second magnet 23 closer to the hall sensor 51, thereby more accurately triggering the hall sensor 51. The end face of the magnet, which is exposed out of the driving wheel, can be a magnetic pole end face, the strength of the magnetic field penetrating through the end face is higher, and the triggering accuracy is higher.

The lock bolt 1 is movably arranged in the lock shell, and the motor 4 can be fixedly arranged in the lock shell. The driving wheel 2 is in transmission connection with the motor 4, and may be directly disposed on the output shaft of the motor 4, or may be in transmission connection with the output shaft of the motor 4 through a reduction gear set. The hall sensor 51 is arranged inside the lock housing.

The bolt 7 is arranged in a movable manner on the lock housing. For example, the lock is a horseshoe lock and the lock bolt 7 is a lock ring. The lock ring can extend out of the lock shell to achieve locking and can also retract into the lock shell to achieve unlocking. The bolt 1 and the lock bolt 7 form a matching relationship.

In the locked state, the lock bolt 7 is in the locked position, and the lock bolt 1 can move to the locked position to limit the position of the lock bolt 7 and prevent the lock bolt 7 from moving to the unlocked position. The circuit board 5 can control the driving wheel to rotate, so as to rotate the position of the driving part 21 to a position capable of limiting the bolt 1 to move to the release position. Therefore, the driving wheel 2 and the lock tongue 1 can perform position locking action on the lock bolt 7, prevent the lock bolt 7 from moving to an unlocking position, and ensure the reliability of locking.
