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 lock mechanism, a lockset and a vehicle of a lockset 100. 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.

FIG. 1 is a schematic diagram of an exemplary lock 100 shown in an off-lock state according to some embodiments of the present application; FIG. 2 is a schematic diagram of an exemplary lock 100 shown in an unlocked state according to some embodiments of the present application. 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. 1-2. 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 switch lock structure of the lock 100 may include a latch bolt 120 and a latch bolt driving device. Specifically, the tongue driving means may be used to drive the movement of the tongue 120.

In some embodiments, the deadbolt actuation means may include a deadbolt toggle 133 and a deadbolt reset 124. Deadbolt toggle 133 may be used to apply a driving force to deadbolt 120 to toggle deadbolt 120 into motion. Deadbolt reset 124 may be used to store and release energy during movement of deadbolt 120 to perform a reset function of deadbolt 120. Specifically, a deadbolt reset 124 (e.g., a spring) may be drivingly connected to deadbolt 120. In an embodiment of the present application, the latch bolt resetting means 124 may be a compression spring. In some alternative embodiments, the deadbolt reset mechanism 124 may also be a tension spring, a coil spring, or the like. In some embodiments, the deadbolt toggle 133 may include a power device and a toggle portion; the toggle part is in transmission connection with the power device, and the toggle part is driven by the power device to move so as to toggle the lock tongue 120 to move. In the embodiment of the present application, the power device may be a motor 131, and the toggle part may be a cam 132. In some embodiments, the cam 132 may be in the shape of two cylinders with end surfaces that are fixedly attached to each other. The large cylinder is fixedly arranged on a rotating shaft of the motor 131, the end face of the small cylinder is fixedly connected with the end face of the large cylinder, and the position of the small cylinder deviates from the rotating center of the large cylinder. Preferably, the circumference of the small cylinder may be tangential to the circumference of the large cylinder. Preferably, the diameter of the small cylinder may be less than half of the diameter of the large cylinder, e.g., the diameter of the small cylinder may be 1/3, 1/4, etc. of the diameter of the large cylinder. The latch tongue 120 may be provided with a second protrusion 122 for the cam 132 (e.g. a small cylinder on the cam 132) to abut against. When the cam 132 rotates, the cam 132 (e.g., a small cylinder on the cam 132) is pressed against and separated from the second protrusion 122, so as to drive the latch tongue 120 to move.

In some embodiments, the motor 131 may be a geared motor. In some alternative embodiments, the deadbolt toggle 133 may also be a reciprocating drive mechanism such as a crank and rocker mechanism. For example, the power device may be the motor 131 and the toggle portion may be a rocker. In some alternative embodiments, deadbolt toggle 133 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 structure may further include a first sensor 150, and the first sensor 150 may be used to detect the movement of the lock pin.

In some embodiments, the first sensor 150 may comprise a magnetically controlled switch (e.g., a magnetic induction sensor), and the locking pin 110 may include an element (e.g., a magnet 152) for generating a magnetic field. The magnetic switch can determine the movement of the lock pin through the strength of the magnetic field generated by the element (such as the magnet 152). In some embodiments, the magnet may be disposed at any position on the locking pin 110, and the magnetically controlled switch may be disposed near a position in the movement trace of the magnet, such as directly above or directly below the position. When the lock pin 110 moves, the magnet passes (e.g., approaches and/or moves away) from a position corresponding to the magnetic switch, and the magnetic switch can determine the movement of the lock pin 110 by receiving the intensity of the magnetic field generated by the magnet. For example, the magnetic switch may generate an electrical signal that reflects the magnitude of the detected magnetic field, and the controller may process (e.g., compare) the electrical signal to determine the movement of the magnet and, thus, the movement of the locking pin 110.

In some embodiments, the first sensor 150 may also determine the movement of the locking pin by detecting whether the locking pin 110 is in the locking pin preset position. For example, when first sensor 150 is a magnetically controlled switch, a magnetic field generating element (e.g., a magnet) may be provided at the location where the trailing end of locking pin 110 is coupled to locking pin reset device 140. The magnetic switch may generate an electrical signal reflecting the detected magnitude of the magnetic field by receiving a magnetic field strength signal generated by the magnet 152, and the magnetic switch may be in signal connection (e.g., electrically connected) with the controller, and the controller receives an output signal of the magnetic switch and determines whether the lock pin 130 reaches the preset position based on the output signal. For example, the pin preset position may be the position of the pin 110 when the lock is closed. When the controller determines that the lock pin is moved to the preset position based on the output of the first sensor 150, the lock pin may be considered to be moved. Compared with other induction elements, the magnetic control switch 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 magnetic switch 151 may include any sensor that detects using a magnetic field sensing principle, such as a hall sensor, 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.), and the like.

In some alternative embodiments, the first sensor 150 may be other sensors. For example, the first sensor may be a photosensor such as a groove type photosensor, an opposite type photosensor, a reflector type photoelectric switch, a diffusion reflection type photoelectric switch, or the like. Specifically, a first blocking piece or a first light source may be fixedly disposed on the lock pin 110, and the first blocking piece or the first light source is used for changing the intensity of light entering the photoelectric sensor when the lock pin 110 moves, so that whether the lock pin 110 moves can be determined from the output signal of the photoelectric sensor. For another example, the first sensor may be a tact switch; the latch 110 (e.g., the end of the latch 110) may turn the tact switch on or off when moving, so that the movement of the latch 110 may be judged by the state of the tact switch. As another example, the first sensor may be any sensor capable of detecting movement of the locking pin 110. For example, the first sensor 150 may also be a pressure sensor, an infrared sensor, or the like.

In an embodiment of the present application, the switch lock structure may further include a second sensor 160, and the second sensor 160 may be used to detect a position of the locking bolt.

In some embodiments, the second sensor 160 may include a tact switch, and the latch 120 may include an element (e.g., the first protrusion 123) thereon for contacting/disengaging the tact switch (e.g., the tact switch protrusion 161). For example, when the latch bolt 120 moves away from the latch pin 110, the first protrusion 123 touches the tact switch (e.g., closes the tact switch); when the latch 120 moves toward the latch 110, the first protrusion 123 is disengaged from the tact switch (e.g., the tact switch is turned on). In other embodiments, the second sensor 160 may include a magnetic induction sensor, and the top end of the latch bolt 120 may be provided with an element (e.g., a magnet) for generating a magnetic field. So that the magnetic induction sensor can determine the position of the latch bolt 120 according to the intensity of the magnetic field generated by the magnet. In other embodiments, the second sensor 160 may further include a photosensor, such as a groove photosensor, a correlation type photosensor, a reflector type photoelectric switch, a diffusion reflection type photoelectric switch, or the like. The rear end of the latch tongue 120 may be provided with an element (e.g., a shutter or a reflector) for changing a light beam. The photoelectric sensor may thus determine the position of the deadbolt 120 by detecting the obstruction or reflection of the light beam. In other embodiments, second sensor 160 may also include a pressure sensor, such as a piezoresistive pressure sensor, a sapphire pressure sensor, a diffused silicon pressure sensor, a ceramic pressure sensor, a piezoelectric pressure sensor, or the like. The latch tongue 120 may be provided at a top end thereof with an element (e.g., a first protrusion 123) for contacting/disengaging a pressure sensor. So that the pressure sensor can determine the position of the latch bolt 120 by detecting the change in pressure applied by the protrusion. Wherein, the first protrusion 123 may be replaced by a rod-like, sheet-like or block-like structure, etc. fixedly connected to the position.

In some embodiments, the second sensor 160 may be used to detect whether the deadbolt 120 is in a preset position. For example, the latch preset position may be a position where the latch 120 is disengaged from the recess of the lock pin 110. In the embodiment shown in fig. 1-2, the second sensor 160 may be a tact switch, and the latch is provided with an element (e.g., the first protrusion 123) for contacting/disengaging the tact switch, and the tact switch outputs different signals in different states (on or off). The tact switch may be in signal connection (e.g., electrically connected) with the controller, and the controller receives an output signal of the tact switch, and determines whether the latch 120 is located at a preset position based on the output signal, so as to determine the on-off state of the lock 100. As shown in fig. 1, the lock is in the off state, and at this time, the locking tongue 120 is separated from the tact switch, and the locking tongue is not in the locking tongue preset position. As shown in fig. 2, in the unlocked state, the locking bolt 120 touches the tact switch, and the locking bolt is located at the locking bolt preset position.

In some embodiments, a deadbolt toggle 133 may be used to actuate movement of the deadbolt 120 based on movement of the lock pin 110. For example, when the latch 110 moves, indicating that the user has the intention to lock, the deadbolt moving device 133 may move for a certain time, displacement or angle, so that the deadbolt moving device 133 releases the restriction of the deadbolt and reserves the space for the deadbolt to return. At this point, locking pin 110 may continue to move (or may have moved into position) until recess 130 on locking pin 110 is aligned with the end of locking bolt 120, at which point locking bolt 120 may snap into recess 130 on locking pin 110 upon actuation of the bolt return mechanism.

In some embodiments, a deadbolt toggle 133 may be used to actuate movement of the deadbolt 120 based on movement of the lock pin 110 and the position of the deadbolt 120. For example, when the lock is closed, the deadbolt toggle 133 may actuate the deadbolt 120 to move based on the movement of the deadbolt 110. When unlocking, the locking bolt toggle device 133 can drive the locking bolt 120 to move based on the position of the locking bolt 120; for example, the deadbolt toggle 133 may stop moving when the deadbolt 120 is in a preset position out of the recess 130. In some embodiments, the deadbolt toggle 133 may also be used to actuate the deadbolt 120 to move when the lock pin 110 has moved and the deadbolt 120 is in the deadbolt preset position. For example, in an unlocked state, locking bolt 120 may disengage from locking bolt 110 (rather than abut) where movement of locking bolt 110 may reflect the user's intent to close the lock; based on the locking intention of the user and the position of the locking bolt 120 in the preset position (i.e., the position separated from the lock pin 110), the locking bolt toggle device 133 may drive the locking bolt 120 to move until the locking bolt toggle device 133 releases the restriction on the locking bolt 120 and reserves a space for the locking bolt 120 to return. At this time, the latch 120 may be pressed against the lock pin 110 by the latch resetting device. In some embodiments, deadbolt toggle 133 may include a motor 131 and a cam 132. Specifically, the controller may control the motor 131 to drive the cam 132 to rotate continuously for a preset time or angle, so that the distance between the cam 132 and the protrusion of the locking tongue 120 is greater than or equal to the distance between the end of the locking tongue 120 and the bottom of the groove 130, or the small cylinder of the cam 132 is not located on the reset path of the locking tongue 120, and the locking tongue 120 may be reset under the thrust of the locking tongue resetting device 124 and abut against the lock pin 110.

In some embodiments, the switch lock mechanism may further include a controller that may be in signal communication (e.g., electrically connected) with the first sensor 150, the second sensor 160, and the deadbolt actuation device (e.g., the motor 131 in the deadbolt actuation device). The controller may be configured to control the deadbolt actuation mechanism based on the output signals of the first and

second sensors

150, 160. In some embodiments, the controller may be implemented by the control system described in fig. 3.

The present application further discloses a latch 100, and the latch 100 may include the switching lock mechanism described in any of the embodiments of the present application. In some embodiments, lock 100 may further include a housing, a locking pin 110, and a locking pin return 140.

In the embodiment shown in fig. 1-2, locking pin 110 is movably disposed within the housing, and locking pin 110 may include a recess 130 for receiving at least a portion of locking bolt 120 (e.g., an end of locking bolt 120). In some embodiments, locking pin 110 may be a locking ring that may be used to pass through the spoke clearance of the wheel when the lock is closed to limit rotation of the wheel. In some embodiments, the recess 130 in the lock pin 110 may also be a lock hole. The pin return apparatus 140 is drivingly connected to the lock pin 110, and the pin return apparatus 140 is operable to return the lock pin 110 when unlocked. In some embodiments, the latch pin return device 140 may be a spring (e.g., a tension spring). The latch tongue 120 is movably disposed in the housing such that at least a portion of the latch tongue 120 can enter and exit the lock hole or groove 130. For example, to enable the end of the locking bolt 120 to engage or disengage with a locking hole or recess 130 on the locking pin 110. The latch bolt resetting device 124 is drivingly connected to the latch bolt 120, and the latch bolt resetting device 124 can reset the latch bolt 120 when the lock is closed, for example, to make the latch bolt 120 snap into the groove 130 of the lock pin 110. Deadbolt toggle 133 may be used to toggle the deadbolt 120 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 lock 100, such as the latch strike 133, via the control system 300 shown in fig. 3. In an embodiment of the present application, the deadbolt toggle 133, the first sensor 150, and the second sensor 160 may all have signal connections with the controller; the controller may be used to control deadbolt toggle 133 based on movement of lockpin 110 or in conjunction with the position of deadbolt 120.

In some embodiments, a first sensor 150 may be used to sense movement of the locking pin 110 and a second sensor 160 may be used to sense the position of the locking bolt 120. In some embodiments, the controller may be configured to control the deadbolt striking device 133 to release the constraint on the deadbolt 120 when the deadbolt 120 is located at the deadbolt preset position and the lock pin 110 moves, and reserve a return space required when the deadbolt 120 is locked. In the embodiment of the present application, the first sensor 150 (e.g., a magnetic switch) is used to sense the position of the locking tongue 120, and the second sensor 160 (e.g., a tact switch) has a longer service life and higher reliability than the tact switch, compared to the conventional lock 100 in which two tact switches are used and an unlocking mechanism in which a tact switch and a magnetic switch are combined is used. And because the first sensor 150 is relatively durable, the cost of the latch 100 may be greatly reduced.

In an embodiment of the present application, the deadbolt toggle 133 may include a motor 131 and a cam 132; the motor 131 is fixedly arranged in the shell, and the cam 132 is fixedly connected with a rotating shaft of the motor 131. The motor 131 is in signal communication (e.g., electrically connected) with the controller. Cam 132 may be used to toggle the deadbolt 120 relative to the housing upon actuation of motor 131. In some embodiments, after the lock 100 is in the unlocked state and the locking action (e.g., pin movement), the controller may control the motor 131 to drive the cam 132 to rotate for a predetermined time (e.g., 0.5s, 1s, 2s, etc.) or angle (e.g., 3 °, 5 °, 10 °, 60 °, 90 °, etc.), so as to ensure that the cam 132 is disengaged from the second protrusion 122 and the cam 132 does not obstruct the locking bolt 120 when the locking bolt 120 is reset by the pushing force of the locking bolt resetting device 124. In the present application, the motor 131 is preferably a reduction motor. In alternative embodiments, the deadbolt toggle mechanism 133 may be implemented using other suitable means known to those skilled in the art. For example, the deadbolt toggle mechanism 133 may be implemented using a reciprocating drive mechanism such as a crank and rocker mechanism.

In embodiments of the present application, as shown in FIGS. 1-2, the latch pin return 140 may be a spring, such as a tension spring. Specifically, one end of a tension spring may be fixedly disposed on the housing, and the other end of the tension spring may be fixedly connected to the end of the locking pin 110. Further, the tension spring may be in tension when in the locked state. And is in a reduction state in the unlocking state.

In an embodiment of the present application, the deadbolt reset 124 may be a spring, as shown in fig. 1-2. Specifically, one end of the spring may be fixedly disposed on the housing, and the other end of the spring may be connected to the other end of the latch tongue 120. 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. 3 is an exemplary flow chart of a method of controlling latch 100 according to some embodiments of the present application. As shown in fig. 3, the control method 300 of the lock 100 may include the steps of:

at step 310, movement of the locking pin 110 is detected, and in particular, step 310 may be performed by a detection module 410. In some embodiments, a controller (e.g., the detection module 410) may detect movement of the locking pin 110 based on a first sensor. Specifically, a controller (e.g., the detection module 410) may receive the output signal of the first sensor 150 and determine movement of the lock pin 110 based on the signal of the first sensor 150.

Step 320, detecting the position of the locking bolt 120, specifically, step 320 may be performed by the detection module 410. In some embodiments, a controller (e.g., detection module 410) may determine a position of deadbolt 120 based on a second sensor. In some embodiments, detection module 410 may detect whether deadbolt 120 is in a deadbolt preset position. The preset position may be a position where the locking tongue 120 is far away from (or separated from) the locking pin 110 of the lock 100 (e.g., a position separated from the groove 130, a position separated from the locking pin 110, a position abutting against the locking pin 110, etc.). Specifically, the controller (e.g., the detection module 410) may receive an output signal of the second sensor and determine the position of the locking bolt 120 based on the signal of the second sensor.
