Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

On the contrary, this application is intended to cover any alternatives, modifications, equivalents, and alternatives that may be included within the spirit and scope of the application as defined by the appended claims. Furthermore, in the following detailed description of the present application, certain specific details are set forth in order to provide a better understanding of the present application. It will be apparent to one skilled in the art that the present application may be practiced without these specific details.

The embodiment of the application relates to a switching lock mechanism of a lock, the lock and a vehicle. The vehicle may include a bicycle, an electric vehicle, a balance car, an electric bicycle, a tricycle, etc. The lock can be used for protecting the safety of the vehicle, preventing the vehicle from being stolen, or preventing the vehicle from being illegally used, and the like. In some embodiments, the latch may be separate from the vehicle or may be mounted on the vehicle. In some alternative embodiments, the application scenario of the lockset may not be limited to vehicles. For example, the lock can also be applied to a door lock, a cabinet lock, a box lock and other scenes, and the application is not limited thereto.

Generally, a lockset may include a locking pin and a switch lock mechanism. Wherein the locking pin can be used to change the state of the lock (e.g., open or close the lock). Specifically, the latch may have a variety of shapes, for example, the latch may include an annular latch (e.g., a shackle), a linear latch, a hook-shaped latch, and the like. For example, a lock applied to a vehicle may be a locking ring that may be used to pass through a spoke gap of the wheel to limit rotation of the wheel when in a locked state. Accordingly, the lock may further comprise a pin resetting device for resetting the pin when the lock is unlocked. The locking pin resetting device can be a spring, such as a compression spring, a tension spring, a coil spring and the like. The locking and unlocking mechanism can be used for controlling the mechanical assembly to limit the lock pin, and further controlling the lockset to be opened or closed.

The switching lock mechanism may generally include: the lock bolt driving device can be used for driving the lock bolt to move. Accordingly, the lock pin is generally provided with a lock hole or a groove for accommodating the lock tongue, and the lock tongue can be clamped into or separated from the lock hole or the groove on the lock pin through movement. When the lock tongue is clamped into the lock hole or the groove, the lock opening and closing mechanism limits the movement of the lock pin, so that the lock can be closed; when the lock tongue is separated from the lock hole or the groove, the lock opening and closing mechanism relieves the limitation on the movement of the lock pin, and the lock pin can reset under the action of the lock pin resetting device, so that unlocking can be realized.

The lock opening and closing mechanism, the lock, the vehicle and the control method and system of the lock according to the embodiment of the present application will be described in detail with reference to fig. 1 to 3. It should be noted that the following examples are only for explaining the present application and do not constitute a limitation to the present application.

The locking mechanism of the lock can comprise a lock tongue and a lock tongue driving device. Specifically, the tongue driving means may be used to drive the movement of the tongue 140. In some embodiments, the deadbolt actuation means may have a toggle portion configured to toggle the deadbolt 140 when moved.

In some embodiments, the deadbolt actuation means may include a deadbolt toggle 160 and a deadbolt reset 150. The deadbolt toggle 160 may be used to apply a driving force to the deadbolt to toggle the deadbolt 140. Deadbolt reset 150 may be used to store and release energy during deadbolt movement to perform the reset function of deadbolt 140. Specifically, a deadbolt reset 150 (e.g., a spring) may be drivingly connected to deadbolt 140. In an embodiment of the present application, the deadbolt reset means 150 may be a compression spring. In some alternative embodiments, the deadbolt reset means 150 may also be a tension spring, a coil spring, or the like. In some embodiments, the deadbolt toggle 160 may include a power device and a toggle portion; the toggle part is in transmission connection with the power device and is used for moving under the driving of the power device so as to toggle the bolt 140 to move. In the embodiment of the present application, as shown in fig. 3, the power device may be a motor 161, and the toggle part may be a cam 162. In some embodiments, the cam 162 may be shaped as two cylinders with their end surfaces secured to each other. The large cylinder is fixedly arranged on the rotating shaft of the motor 161, the end surface of the small cylinder 163 is fixedly connected with the end surface of the large cylinder, and the position of the small cylinder 163 deviates from the rotating center of the large cylinder. Preferably, the circumference of the small cylinder 163 may be tangent to the circumference of the large cylinder. Preferably, the diameter of the small cylinder 163 may be less than half of the diameter of the large cylinder, for example, the diameter of the small cylinder 163 may be 1/3, 1/4, etc. of the diameter of the large cylinder. The latch tongue 140 may be provided with a second protrusion 143 for the cam 162 (e.g., a small cylinder 163 on the cam 162) to abut against. When the cam 162 rotates, the cam 162 (e.g., the small cylinder 163 on the cam 162) is pressed against and separated from the second protrusion 143, so as to drive the latch 140 to move.

In some embodiments, the motor 161 may be a geared motor. In some alternative embodiments, the deadbolt toggle 160 may also be a reciprocating drive mechanism such as a crank and rocker mechanism. For example, the power device may be a motor and the toggle part may be a rocker. In some alternative embodiments, the deadbolt toggle 160 may also be a magnetically actuated device. For example, the power device may be an electromagnet, and the toggle part may be a magnetic block driven by the electromagnet.

In an embodiment of the present application, the switch lock mechanism may further comprise a sensor 180, and the sensor 180 may be used to detect the position of the toggle part.

In some embodiments, the sensor 180 may comprise a magnetic induction sensor, and the dial may be provided with an element for generating a magnetic field. Therefore, the magnetic induction sensor can determine the position of the toggle part by sensing the intensity of the magnetic field generated by the element on the bolt 140. In an embodiment of the present application, the sensor 180 may be a hall sensor. The element for generating a magnetic field on the toggle part may be a magnet 181 fixed on the toggle part. Specifically, the hall sensor may include a hall position reference sensor, a hall zero position sensor, a hall stroke sensor, a hall gear sensor, a hall proximity switch, and the like. In some alternative embodiments, the sensor 180 may also include an electromagnetic induction sensor (e.g., a fluxgate sensor, an eddy current sensor, etc.), a magnetoresistive sensor (e.g., a giant magnetoresistive sensor, a magnetostrictive sensor, etc.), or the like. In some embodiments, the sensor 180 may also be a photoelectric sensor, and the dial portion is provided with a light source, a baffle plate or a reflective plate. Specifically, the photoelectric sensor can detect the position of the shifting part by sensing a light source, a baffle or a reflective sheet on the shifting part.

In some embodiments, the sensor 180 may be used to detect whether the toggle portion reaches a preset position. In the embodiment shown in fig. 1-2, the sensor 180 may be a hall sensor, and the dial portion is provided with a magnet 181 for triggering the hall sensor. The hall sensor generates an electric signal reflecting the detected intensity of the magnetic field by receiving the intensity of the magnetic field intensity generated by the magnet 181, and the controller 171 determines the position of the toggle part by processing (e.g., comparing and calculating) the electric signal. In some embodiments, the hall sensor output electrical signal may be proportional to the magnetic field strength it detects. Specifically, a threshold may be set, that is, when the electrical signal output by the hall sensor is greater than the threshold, the controller 171 may determine that the toggle portion has reached the preset position. Compared with other sensing elements, the Hall sensor has the characteristics of no contact, low power consumption, long service life, high response frequency and the like, and can reliably work in various outdoor severe environments after being packaged by resin.

In some embodiments, the latch bolt driving device may be configured to drive the latch bolt 140 to move according to the position of the toggle portion. Specifically, the bolt driving device can be used for stopping moving after the shifting part moves to a preset position. For example, when the deadbolt actuator includes a power device and a toggle portion, the power device (e.g., motor 161) may be configured to control the toggle portion (e.g., cam 162) to stop moving after the toggle portion moves to a predetermined position.

In some embodiments, the lock may also include a switch lock mechanism status detection device 190. The device 190 for detecting the state of the switch lock mechanism can be used for detecting the unlocking or locking state of the lock. In the embodiment shown in fig. 1-2, the device 190 for detecting the status of the switch lock mechanism may be a light touch switch, and the tongue 140 may have a first protrusion 142 corresponding to the light touch switch; the first protrusion 142 may be used to contact or disengage the tact switch when the locking tongue 140 moves relative to the housing, so as to change the state of the tact switch, such as turning on or off. For example, when the latch 140 moves away from the latch pin 120, the first protrusion 142 touches the tact switch (e.g., closes the tact switch); when the latch 140 moves in the direction of the latch pin 120, the first protrusion 142 is disengaged from the tact switch (e.g., the tact switch is turned on). Under different states (on or off), the output signals of the tact switch are different. The tact switch can be in signal connection (such as electrical connection) with the controller, the controller receives an output signal of the tact switch, and the position of the bolt 140 is judged based on the output signal, so that the on-off state of the lockset is judged. As shown in fig. 1, the lock is in the off state, and the first protrusion 142 on the locking tongue 140 is disengaged from the tact switch. As shown in fig. 2, the bolt 140 is in an unlocked state, and the first protrusion 142 touches the tact switch. In other embodiments, the first protrusion 142 may be replaced by a rod, a plate, a block, or the like, which is fixedly connected to the locking tongue 140.

In alternative embodiments, the switch lock mechanism status detection device 190 may be other suitable devices. For example, the on-off lock mechanism state detection device 190 may be a photoelectric sensor; a first blocking piece can be fixedly arranged on the bolt 140; the first blocking piece is used for changing the intensity of light entering the photoelectric sensor when the lock bolt 140 moves relative to the shell, so that the position of the lock bolt 140 is judged, and the unlocking and locking states of the lockset are further judged. For another example, the device 190 for detecting the state of the switch lock mechanism can be any device capable of detecting the position of the bolt 140 to determine the lock state.

In some embodiments, the switch lock mechanism may further include a controller 171, and the controller 171 may have signal connections with the sensor 180 and the deadbolt actuator. The controller 171 may be configured to control the latch bolt driving apparatus according to an output signal of the sensor 180. In some embodiments, the controller may be implemented by the control system described in fig. 5.

The application also discloses a lock which can comprise the switch lock mechanism in any embodiment of the application. In some embodiments, the lock may further include a housing, a locking pin 120, and a locking pin return 130.

In the embodiment shown in fig. 1-2, lock pin 120 is movably disposed within the housing, and lock pin 120 may include a recess 121 for receiving at least a portion of locking bolt 140 (e.g., an end of the locking bolt). In some embodiments, the locking pin 120 may be a locking ring that may be used to pass through a spoke gap of the wheel to limit rotation of the wheel when in the locked state. In some embodiments, the recess 121 in the lock pin 120 can also be a lock hole. The lock pin resetting device 130 may be drivingly connected to the lock pin 120, and the lock pin resetting device 130 may reset the lock pin 120 when the lock is unlocked. In some embodiments, the latch pin return 130 may be a spring (e.g., a tension spring). The latch tongue 140 is movably disposed in the housing such that at least a portion of the latch tongue 140 can enter and exit the lock hole or groove 121. For example, to enable the end of the locking tongue 140 to engage or disengage with a locking hole or groove 121 on the locking pin 120. The latch bolt resetting device 150 is drivingly connected to the latch bolt 140, and the latch bolt resetting device 150 can reset the latch bolt 140 when the lock is closed, for example, the latch bolt 140 is locked in the lock hole or the groove 121 of the lock pin 120. A deadbolt toggle 160 (e.g., toggle portion) may be used to toggle the deadbolt 140 relative to the housing. The controller can receive an instruction, such as an unlocking instruction from a server or a mobile terminal, and control the bolt driving device according to the instruction. In some embodiments, the controller may implement control of other components of the latch, such as the latch strike 160, via the control system 500 shown in FIG. 5. In the embodiment of the present application, the deadbolt toggle 160 and the sensor 180 may both have signal connections with the controller; the controller may be used to control the deadbolt toggle 160 based on the position of the deadbolt 140.

In the embodiment of the present application, as shown in fig. 1-2, when the end of the locking tongue 140 is engaged in the groove 121, the locking pin 120 is fixed, so as to achieve locking; when the controller 171 controls the motor 161 to rotate, the motor 161 drives the cam 162 to rotate, the cam 162 stirs the bolt 140 to move in a direction away from the lock pin 120, when the end of the bolt 140 is separated from the groove 121, the lock pin 120 is not clamped, and because the lock pin resetting device 130 is in transmission connection with the lock pin 120, the lock pin 120 can be controlled to reset under the action of the lock pin resetting device 130, and the lock pin is retracted into the shell, so that unlocking is realized; after unlocking, the controller 171 controls the motor 161 to continue rotating, meanwhile, the sensor 180 detects the rotating position of the cam 162, the controller 171 receives and judges the detection signal of the sensor 180, and when the sensor 180 detects that the cam 162 rotates to a predetermined position, a control signal is generated to the controller 171, wherein the predetermined position can eliminate the resistance of the cam 162 to the rebounding of the latch bolt 140, so as to facilitate the subsequent vehicle locking operation, and therefore, when the controller 171 receives the control signal, the controller 161 stops rotating. In the above-mentioned structure of this application, utilize sensor 180 directly to detect the turned position of cam 162, and then feed back to the rotation of controller 171 control motor 161 according to the testing result, therefore can accurately control cam 162 and rotate to preset position, can not receive the operational environment of whole device or the influence of reasons such as mechanical wear, the deviation appears in the angle that motor 161 continues to rotate promptly, cause spring bolt 140 to kick-back and be obstructed and not arrive, the problem of locking the car trouble appears.

In some embodiments, the lock pin 120 may be provided with a pull ring 122, and the lock pin 120 is moved by the pull ring 122 against the resistance of the lock pin resetting device 130 until the lock hole or the groove 121 is located right below the latch tongue 140, and the latch tongue 140 is pushed into the groove 121 by the latch tongue resetting device 150 to achieve locking.

When the sensor 180 is a hall sensor, the hall sensor is disposed on the circuit board 170, and the cam 162 is provided with a magnet 181 for triggering the hall sensor. The hall sensor detects the magnetic field intensity generated by the magnet 181 in real time, and when the cam 162 rotates by different angles, the magnetic field intensity detected by the hall sensor is different. The installation position of the magnet 181 on the cam 162 is set such that when the hall sensor detects that the magnetic field strength is greater than or equal to the preset threshold value of the magnetic field strength, the cam 162 is just located at a position where it is separated from the latch tongue 140. In some embodiments, the magnetic field strength detected by the hall sensor when cam 162 is not located at a certain position on the reset path of locking bolt 140 may be set to the magnetic field strength threshold, so that when the magnetic field strength detected by the hall sensor satisfies the threshold condition (e.g., is greater than or equal to the magnetic field strength threshold), it can be ensured that cam 162 does not prevent locking bolt 140 from rebounding under the action of locking bolt reset device 150 and allow the end of locking bolt 140 to be completely clamped into groove 121 when the lock is closed. The controller 171 may send a signal to control the motor 161 to stop rotating when it is determined that the hall sensor output signal satisfies the threshold condition. Preferably, the magnet 181 may be disposed at the outer edge of the cam 162, and the hall sensor is disposed at the intersection of the circuit board 170 and the center point of the cam 162 with respect to the perpendicular line of the circuit board 170, that is, the hall sensor is disposed on the circuit board 170 below the cam 162. The center point may be a geometric center point of the cam 162 or a rotational center point of the cam 162.

When the sensor 180 is a photoelectric sensor, a reflector (not shown) for triggering the photoelectric sensor is provided on the cam 162. In some embodiments, the photosensor is turned on and emits a light signal in a fixed direction. The position of the reflector on the cam 162 is set, so that when the cam 162 rotates to a certain position during unlocking, the light signal emitted by the photoelectric sensor can be emitted onto the reflector, the reflector can reflect the light signal to the photoelectric sensor, and the cam 162 is separated from the bolt 140. In some embodiments, the light intensity detected by the photosensor when the cam 162 is not located at a position in the reset path of the locking bolt 140 may be the light intensity threshold, so that the cam 162 is not located in the reset path of the locking bolt 140 when the magnetic field intensity detected by the photosensor satisfies a threshold condition (e.g., equal to or greater than the light intensity threshold), so as to ensure that the cam 162 does not prevent the locking bolt 140 from rebounding under the action of the locking bolt resetting device 150 and completely clamping the end of the locking bolt 140 into the groove 121 when the lock is closed. The controller 171 determines that the cam 162 rotates to a predetermined position and controls the motor 161 to stop rotating. In some embodiments, a baffle may be used instead of a retroreflective sheeting. The photoelectric sensor includes a light emitting portion and a light receiving portion that are separated. The position of the shutter on the cam 162 is set so that, when the cam 162 rotates to a certain position during unlocking, the shutter is in a propagation path of light from the photosensor light emitting unit to the light receiving unit, and the cam 162 is disengaged from the locking tongue 140. The light receiving section receives no light or only a small amount of light, and its output signal changes. In still other embodiments, the reflector may be replaced with a light source.

In this application, the locking pin resetting device 130 may be a spring, such as a tension spring, one end of the tension spring is fixedly disposed on the housing, and the other end of the tension spring is disposed at the end of the locking pin 120. When the lock is locked, the tension spring is in a tensioned state; when the lock is unlocked, the end of the locking bolt 140 is disengaged from the groove 121 of the locking pin 120, so that the locking pin 120 is reset and moves towards the direction of the tension spring under the action of the tension spring, and the unlocking is realized. Furthermore, the tension spring can be in a stretching state when in a locking state; and is in a reduction state in the unlocking state.

In this application, the latch bolt resetting means 150 may be configured as a spring, one end of the spring is fixed on the housing, and the other end of the spring is disposed at the end of the latch bolt 140. When the lock is unlocked, the bolt 140 moves in a direction away from the lock pin 120 against the resistance of the spring under the action of the bolt toggle device 160 until the end of the bolt 140 is separated from the lock hole or the groove 121 on the lock pin 120; further, the deadbolt manipulation mechanism 160 releases the blocking of the reset of the deadbolt 140, and the deadbolt 140 is pushed toward the lock pin 120 by the spring. When the lock is locked, the lock pin 120 is under the action of tension and moves to the direction far away from the tension spring to the lock hole or the groove 121 under the bolt 140, the bolt 140 continues to move to the lock hole or the groove 121 under the action of the spring to the end of the bolt 140 to be pushed into the lock hole or the groove 121, and locking is achieved. Further, the spring may be in a compressed state in the unlocked state; and in the locking state, the lock is in a reduction state.

FIG. 4 is an exemplary flow chart of a lock control method according to some embodiments of the present application. As shown in fig. 4, a method 400 of controlling a lock may include the steps of:

and step 410, controlling the bolt driving device to move so as to execute unlocking. Specifically, step 410 may be performed by unlocking module 510.

In some embodiments, when unlocking, the controller 171 (e.g., unlocking module 410) may receive an unlocking command and control the movement of the bolt driving device to perform unlocking based on the unlocking command. The unlocking instruction can be an unlocking instruction sent by the server and/or the mobile terminal. Specifically, the controller 171 can control the power device (e.g., the motor 161) to move to drive the toggle portion (e.g., the cam 162) to rotate, the rotation of the cam 162 toggles the bolt 140 to move in the direction of disengaging from the lock hole or the groove 121 until the bolt 140 disengages from the lock hole or the groove 121 of the lock pin 120, and the lock pin 120 is restored (e.g., retracted into the housing) under the action of the lock pin resetting device 130 to achieve unlocking.

In step 420, the position of the toggle part in the deadbolt actuation mechanism is determined. In particular, step 420 may be performed by detection module 520.

In some embodiments, the controller (e.g., the detection module 520) may determine multiple positions (e.g., arbitrary positions) of the dial based on the sensor 180. In some embodiments, the controller (e.g., the detection module 520) may also determine whether the locking bolt 140 reaches a preset position based on the sensor 180. Specifically, the preset position is a position where the toggle part is separated from the lock tongue. For example, the predetermined position is a position where the cam 162 releases the constraint on the latch tongue 140 and a return space required when the latch tongue 140 is locked is reserved. Specifically, the sensor 180 may be a hall sensor disposed on the circuit board 170, and the cam 162 is provided with a magnet 181 for triggering the hall sensor. In the unlocking process or after, the Hall sensor detects the magnetic field intensity, and when the Hall sensor detects that the magnetic field intensity is greater than a preset magnetic field intensity threshold value, the fact that the shifting part in the lock bolt driving device reaches a preset position is determined. In some alternative embodiments, the sensor 180 is a photoelectric sensor, and a light source, a shutter, or a reflector for triggering the photoelectric sensor is disposed on the cam 162; when the optical signal received by the photosensor changes (e.g., increases or decreases) during unlocking, the controller 171 determines that the cam 162 has rotated to a predetermined position.

And step 430, controlling the bolt driving device based on the position of the toggle part. Specifically, step 430 may be performed by deadbolt actuator control module 530.

In some embodiments, the controller 171 (e.g., the latch actuator control module 530) controls the latch actuator to stop moving when the toggle reaches a predetermined position. For example, the motor 161 is controlled to stop rotating.

The steps when the lockset locks can be as follows: when the lock pin 120 moves relative to the housing under the action of tension until the lock hole or the groove 121 on the lock pin 120 is aligned with the lock tongue, the lock tongue 140 moves towards the lock pin 120 under the action of the lock tongue resetting device 150 until the end part of the lock tongue 140 is clamped into the lock hole or the groove 121 on the lock pin 120, and locking is achieved.

It should be noted that the above description related to the flow 400 is only for illustration and explanation, and does not limit the applicable scope of the present application. Various modifications and changes to flow 400 may occur to those skilled in the art in light of the teachings herein. However, such modifications and variations are intended to be within the scope of the present application. For example, the three steps of the control method 400 may be performed sequentially according to a flow sequence or may be performed simultaneously. For another example, step 410 may be performed first, and then steps 420 and 430 may be performed simultaneously.
