Research discovers, along with the improvement of people's traffic safety consciousness, for guaranteeing the safety problem of riding, has been equipped with the helmet for the bicycle mostly, however, for avoiding the helmet to lose the improvement of the helmet cost that causes, need set up helmet lock for the helmet. Most of helmet locks arranged at present adopt technologies such as Radio Frequency Identification (RFID) and Hall detection, but adopt the scheme of RFID Identification helmets, require a built-in RFID chip, and an RFID card reader is arranged in the lock, so that the hardware cost is higher, the maintainability is low, and meanwhile, additional structural design cost is increased. In addition, the scheme of adopting the Hall recognition helmet is easy to interfere and limited in cheating prevention.

Based on the research, the present disclosure provides a helmet lock, a helmet lock control method, device, equipment, medium, and a product, which utilize simple components to achieve the function of the helmet lock, reduce the cost of the helmet lock, and utilize a specific locking protocol, that is, the lock can be successfully locked only when the extension amount is within a first preset range, thereby effectively reducing the deception of locking.

The above drawbacks are the results of the inventor after practical and careful study, and therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in the following description should be the contribution of the inventor to the present disclosure in the course of the present disclosure.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In order to facilitate understanding of the embodiment, a helmet lock disclosed in the embodiment of the present disclosure is first described, and the helmet lock provided in the embodiment of the present disclosure may be applied to a shared bicycle, a shared electric bicycle, a bicycle, an electric bicycle, a motorcycle, and other vehicles. Referring to fig. 1, it is a schematic structural view of a helmet lock. The lock comprises a first detection device 11, a bolt control device 12 and a bolt 13. The bolt control device 12 is connected with the bolt 13, and the bolt control device 12 can control the bolt 13 to extend or retract.

The locking tongue 13 is located at a first preset position in the unlocked state of the helmet lock, as indicated by 14 in fig. 1, i.e. the position at which the locking tongue stops in the unlocked state of the helmet lock.

The first detection device 11 is in communication with the deadbolt control device 12, and in some embodiments, the first detection device feeds back a signal to the deadbolt control device, which may be a lock-off signal, i.e., a signal to turn off the helmet lock.

The first detection means 11 is configured to detect the lock-off control operation and feed back a lock-off signal to the tongue control means.

For example, the first detecting means may be a pressure detecting means, and the locking control operation may be an operation in which the user linearly presses the helmet, where the pressure detecting means detects the locking control operation by detecting the pressure. When the pressure detection device detects the locking control operation, a locking signal, namely a signal for closing the helmet lock, can be fed back to the bolt control device.

For example, the first detection device may also be another sensor capable of detecting the locking control operation, such as an infrared sensor or a photoelectric sensor.

The bolt control device 12 is configured to control the bolt to extend when receiving a lock closing signal; and acquiring the extension amount of the lock tongue, controlling the lock tongue to retract to a first preset position in an unlocking state under the condition that the extension amount is not within a first preset range, and sending a lock closing failure signal to remote equipment.

Here, the first preset range belongs to a specific locking protocol of the helmet lock, which is set by a developer to prevent a user from having a fraudulent locking. When the lock tongue stops, the extending amount is within a first preset range, and the lock is successfully closed; otherwise, the lock is failed to be closed. It should be noted that the first predetermined range includes the maximum and minimum values of the range. Illustratively, the first predetermined range may be from 24mm to 26mm, including a minimum of 24mm and a maximum of 26mm within the range.

The first preset range may also be a suitable range according to a specific application scenario, which is not limited in the embodiment of the present disclosure. Without departing from the scope of the present disclosure, one skilled in the art may make various modifications to the specific scope of the first preset range, and such modifications are intended to fall within the scope of the present disclosure.

Here, the extension of the bolt is controlled in case of receiving the lock-off signal sent by the first detection device, and in a possible embodiment, the extension amount of the bolt is acquired when the bolt stops moving. In another possible implementation mode, the extending amount of the lock tongue is determined in real time during the moving process of the lock tongue, and when the extending amount of the lock tongue exceeds the maximum value of the first preset range, the lock tongue is not waited to stop, the lock tongue is directly controlled to retract to the first preset position in the unlocking state, and a lock closing failure signal is sent to the remote equipment.

Illustratively, the remote device includes a client or a cloud server of a helmet lock, and the like. The lock closing failure signal can be used for prompting a user and/or a cloud server that the lock closing fails; the user can determine that the current locking is failed through the locking failure information, and then can continue to execute the locking operation until the helmet is locked successfully. The cloud server can determine the current user lock closing failure times by recording the lock closing failure information, or determine whether the helmet stealing phenomenon occurs or not based on the user order information and the lock closing failure information. Specifically, when the cloud server detects that the order information of the current user indicates that the order is completed, but the locking of the helmet is failed, the current user can be considered to be stolen, and the user is prompted to return to the helmet as soon as possible.

See fig. 2, which is a schematic view of the internal structure of the helmet lock. The tongue control device 12 includes a tongue driving device 121 and a controller 122; deadbolt actuation assembly 121 includes a motor 1211 and an actuator 1212. Here, the first detection device 11 is in communication connection with the controller 122; the tongue driving device 121 is communicatively connected to the controller 122, and specifically, the motor 1211 in the tongue driving device 121 is communicatively connected to the controller 122.

The latch bolt control device 12 is connected to the latch bolt 13, specifically, the latch bolt 13 is connected to the actuator 1212, the actuator 1212 is connected to the motor 1211, and the motor 1211 is connected to the controller 122 in communication.

Here, the motor 1211 can drive the latch bolt 13 to extend or retract through the actuator 1212.

The first detection means 11 is configured to feed back a lock-off signal to the controller.

The controller 122 is configured to control the latch bolt driving device to drive the latch bolt to extend when receiving the locking signal; and acquiring the extension amount of the lock tongue, and controlling the lock tongue driving device to drive the lock tongue to retract to a first preset position in an unlocking state under the condition that the extension amount is not within a first preset range.

Here, the motor can drive the spring bolt to stretch out under the control of controller, and specifically, the controller sends corotation pulse to the motor, and the motor passes through actuating mechanism drive spring bolt and stretches out.

And continuing to obtain the extending amount of the bolt when the bolt stops moving. During specific implementation, the controller can obtain a first working current value of the motor in the process of driving the bolt to extend, and when the first working current value is higher than or equal to a first preset threshold value, the bolt is controlled by the bolt driving device to stop moving, and the extending amount of the bolt is obtained.

Here, the manner in which the controller acquires the first operating current value of the motor includes: the motor may send a first operating current value to the controller for the motor when the deadbolt is extended, or, the first working current value of the motor can be based on a current detection device for detecting the current value of the motor when the bolt fed back to the controller extends. The manner of obtaining the first operating current value by the controller in the embodiment of the present disclosure includes, but is not limited to, the two manners, and other sensors capable of obtaining the motor current value may be used to feed back the current value to the controller.

Here, there is great difference between the operating current value of motor when normal work and the operating current value that is hindered to rotate, therefore, can judge whether the spring bolt needs to stop moving through the operating current value of motor.

After obtaining the first working current value, the controller judges whether the first working current value is higher than or equal to a first preset threshold value, after comparison, if the first working current value is higher than or equal to the first preset threshold value, it can be determined that the current bolt is blocked by external force and needs to be controlled to stop moving, and then the extending amount of the bolt is determined. For example, the first preset threshold may be a locked-rotor current of the motor, such as 0.6A. The normal operation current value in the motor operation state may be a rated current of the motor in the normal operation state, such as 0.16A.

The reason that the first working current value is higher than or equal to the first preset threshold value comprises a blocked external force when the bolt extends out, wherein the blocked external force can be an external force blocked by a baffle in a groove of the helmet, and the normal locking state is realized at the moment; the external force blocked by the user can also be used, and the locking state is abnormal.

And if the first working current value is within the range of the normal working current value, determining that the current bolt is not blocked by external force and can continue to extend. Illustratively, the normal operating current value may range from 0.15 to 0.17A.

The range of the normal operating current value and the first preset threshold may also be determined according to empirical values, and the embodiment of the present disclosure is not particularly limited.

In one possible embodiment, the controller determines the current amount of extension of the deadbolt, and in particular, the controller is configured to determine the amount of extension of the deadbolt based on the number of pulses, a first drive parameter of the motor, and a second drive parameter of the actuator.

For example, the motor may be a stepping motor, and specifically, the first driving parameter of the motor includes a step angle θ of the stepping motor, and a subdivision number C of a driver of the stepping motor; under the condition that the actuating mechanism is a lead screw nut, the second driving parameters of the actuating mechanism comprise the thread pitch P and the thread number n of the lead screw; in the case of a rack and pinion actuator, the second drive parameters of the actuator include the module m and the number z of teeth of the gear.

Continuing with the above example, taking the actuator as a lead screw nut, when the step angle θ, the pitch P of the lead screw and the number n of thread starts are known, the number of pulses of one rotation of the stepping motor, i.e., the number of pulses of one rotation of the stepping motor is first determined

Then, based on the subdivision number C, the number of pulses of one rotation of the stepping motor is determined, i.e. the number of pulses of one rotation of the stepping motor is determined

Then, the length l of one turn of the stepping motor is determined ₁ I.e. l ₁ = P × n, and determines the linear displacement of a pulse

Then, the controller determines the number N of pulses within a period of time from the time of extending the latch tongue to the time of stopping the latch tongue according to the recorded number of pulses sent to the stepping motor, and determines the extending amount f of the latch tongue based on the number N of pulses, namely, f = N × x ₁ 。

Continuing with the above example, taking the actuator as a rack and pinion, the step angle θ, the module m of the gear, the number of teeth z, and the number of pulses of one rotation of the stepping motor, i.e. the number of teeth, are known

And determining the number of pulses of one rotation of the stepping motor based on the subdivision number C, i.e. determining the number of pulses of one rotation of the stepping motor

In the case of (2), the length l of one rotation of the stepping motor is determined ₂ I.e. l ₂ = m × z, and determines the linear displacement of a pulse

Then, the controller determines the number N of pulses in a period of time from the stretching time to the stopping time of the lock tongue according to the recorded number of the pulses sent to the stepping motor, and determines the stretching amount f of the lock tongue based on the number N of the pulses, namely f = N x ₂ 。

Aiming at the situation that the extending amount of the bolt is determined in real time in the moving process of the bolt in the embodiment, the extending amount of the bolt can be determined in real time in the mode of determining the extending amount of the bolt, and under the condition that the extending amount of the bolt is smaller than the minimum value of a first preset range and the bolt is not in a stop state, the bolt is controlled to continue to extend; and under the condition that the extension amount of the lock bolt is larger than the maximum value of the first preset range and the lock bolt is not in a stop state, controlling the lock bolt to continuously retract to a first preset position in an unlocking state.

In a possible embodiment, the helmet lock further comprises a second detection device 15, which can be used to detect whether the currently extended bolt needs to stop extending.

The second detecting device 15 is configured to detect the first stop operation and feed back a first stop signal to the tongue control device; the first stopping operation is a stopping operation during the bolt extending process.

The tongue control device 12 is configured to control the tongue to stop extending and acquire the extending amount of the tongue in the case of receiving the first stop signal.

Here, the second detection device may be a pressure detection device, and the first stopping operation may be an operation in which the lock tongue is blocked when extending, and for example, the first stopping operation may include an operation in which the user blocks the lock tongue to continue to extend, an operation in which the lock tongue is blocked by a foreign object to extend, an operation in which the lock tongue is blocked by a barrier in the helmet groove to continue to extend, and the like.

The pressure detection means detects the first stop operation by detecting the pressure. When the second detecting means detects the first stop operation, a stop signal, that is, a first stop signal may be fed back to the latch bolt control means. And when the controller receives the first stop signal, the motor is controlled to stop rotating, so that the bolt is controlled to stop extending, and then the extending amount of the bolt within the time length from the beginning to the stopping of extending is obtained. Here, the manner of obtaining the extension amount may refer to the manner of determining the extension amount of the lock tongue, and repeated details are not repeated.

After the bolt stops extending, determining that the extending amount of the bolt is not located in a first preset range, and controlling the bolt to retract to a first preset position in an unlocking state by a controller, wherein in the retracting process of the bolt, the configuration of a motor and the controller comprises the following steps:

the motor 1211 is configured to drive retraction of the bolt under control of the controller.

The controller 122 is configured to obtain a second operating current value of the motor during driving the bolt to retract, and control the bolt to stop moving through the bolt driving device when the second operating current value is higher than or equal to a second preset threshold value.

For example, during retraction of the deadbolt, the controller may send a reverse pulse to the motor, which drives the deadbolt to retract via the actuator.

Here, the manner in which the controller acquires the second operating current value of the motor includes: the motor may transmit the second operating current value at the time of retraction to the controller, or may be a second operating current value at the time of retraction of the motor fed back to the controller based on a current detection device that detects a current value of the motor.

After the controller obtains the second working current value, it is determined whether the second working current value is higher than or equal to a second preset threshold, and after the comparison, if the second working current value is higher than or equal to the second preset threshold, it can be determined that the current lock tongue is blocked by the external force and the lock tongue needs to be controlled to stop moving, for example, the second preset threshold may be a locked-rotor current of the motor, such as 0.6A.

Here, the reason why the second operating current value is higher than or equal to the second preset threshold includes that the bolt encounters a blocking external force when retracting, and the blocking external force may be a force blocked by the blocking plate in the helmet lock groove.

And if the second working current value is within the range of the normal working current value, determining that the current bolt is not blocked by external force, and continuing to retract.

The second preset threshold may also be determined according to an empirical value, and the embodiment of the present disclosure is not particularly limited.

In a possible embodiment, the helmet lock further comprises a third detection device 16, with which it can be detected whether the currently retracted bolt needs to stop retraction.

The third detection device 16 is configured to detect a second stop operation and feed back a second stop signal to the tongue control device; the second stopping operation is a stopping operation in the process of retracting the bolt;

the latch bolt control device 12 is configured to control the latch bolt to stop retracting upon receiving a second stop signal.

Here, the third detecting means may be a pressure detecting means, and the second stopping operation may be an operation in which the latch bolt is blocked when retracted, and for example, the second stopping operation may include an operation in which the visor in the helmet lock recess blocks the latch bolt from continuing to retract.

The pressure detection means detects a second stop operation by detecting the pressure. When the second detection means detects the second stop operation, a stop signal, i.e., a second stop signal, may be fed back to the latch bolt control means. And when the controller receives a second stop signal, the motor is controlled to stop rotating, and then the bolt is controlled to stop retracting.

Here, the third detecting means may be installed at a target position where the third detecting means can detect that the latch bolt is retracted and at the first preset position, and thus, the controller may stop the latch bolt at the first preset position by receiving the second stop signal.

In a possible embodiment, the helmet lock further comprises a spring 17 with which the helmet in the unlocked state can be pushed out of the helmet lock. In particular, the spring 17 is configured to urge the helmet to eject the helmet lock in the unlocked state of the helmet lock.

In order to further understand the embodiments of the present disclosure, the helmet lock control method provided by the embodiments of the present disclosure is described below by taking the execution main body as the controller.

Referring to fig. 3, a flowchart of a helmet lock control method provided in an embodiment of the present disclosure is shown, where the method includes steps S301 to S303, where:

s301: under the condition of receiving a locking signal transmitted by the first detection device, controlling the bolt to extend out;

s302: acquiring the extending amount of a lock tongue;

s303: and under the condition that the extension amount is not within the first preset range, controlling the lock tongue to retract to the first preset position in the unlocking state, and sending a lock closing failure signal to the remote equipment.

In one possible embodiment, the deadbolt control mechanism further comprises a deadbolt actuation mechanism; the bolt driving device comprises a motor; for S302, in specific implementation, a first working current value of the motor in the process of driving the bolt to extend is obtained; and under the condition that the first working current value is determined not to be within a second preset range, controlling the bolt to stop moving through the bolt driving device, and acquiring the extension amount of the bolt.

In a possible embodiment, before obtaining the protruding amount of the lock tongue, the method further includes:

In one possible embodiment, the deadbolt actuation assembly further includes an actuator;

the acquiring of the extending amount of the lock bolt comprises the following steps:

In a possible embodiment, the helmet lock further comprises a second detection device;

the obtaining of the protruding amount of the lock tongue comprises:

In a possible embodiment, the helmet lock further comprises a third detection device;

In each of the above possible embodiments, reference may be made to the related description in the above helmet lock, and repeated descriptions are omitted.

In a possible embodiment, in order to prevent the user from frequently performing the lock-off control operation within a period of time, a lock tongue locking mechanism may be further provided, that is, the lock tongue is no longer controlled to extend for a second preset time period.

In specific implementation, after the current locking failure is determined, the times of receiving the locking signal in a first preset time length are judged; and under the condition that the number of times of the received locking closing signal is greater than the preset number of times, determining that the bolt is not controlled to extend out within a second preset time.

Here, the lock closing signal is a signal of closing the helmet lock, which is fed back to the controller by the first detection device, and since the first detection device feeds back the lock closing signal to the controller by detecting the lock closing control operation, but the lock closing control operation includes an erroneous operation or a fraudulent operation, the first detection device may detect the lock closing control operation many times within a short period of time, that is, within a first preset period of time, in which case, the controller is required to determine the number of times of receiving the lock closing signal within the first preset period of time, and if the number of times of receiving the lock closing signal is greater than the preset number of times, the controller may no longer send a forward pulse to the motor within a second preset period of time, that is, the lock tongue is kept in a stationary state at the first preset position within the second preset period of time.

In a possible embodiment, in a scenario where the user borrows the helmet, the user-side client may be further used to send an unlocking signal to the controller, and then the controller controls the locking tongue to retract to the first preset position in the unlocking state when receiving the unlocking signal.

Here, the unlock signal is an unlock signal that the client feeds back to the controller based on the unlock control operation.

For example, the unlocking control operation may be an operation in which the user clicks a helmet unlocking button in the client.

It will be understood by those skilled in the art that in the method of the present invention, the order of writing the steps does not imply a strict order of execution and any limitations on the implementation, and the specific order of execution of the steps should be determined by their function and possible inherent logic.
