DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0048] The present application provides a door lock control device, please refer to Figure 1 , Figure 1A structure schematic diagram of a door lock control device provided by an embodiment of the present application.

[0049] The door lock control device comprises a door lock mechanism 1, a first door lock actuator 2, a second door lock actuator 3, and a central control body 4. The first door lock actuator 2 is connected to the door lock mechanism 1; the second door lock actuator 3 is connected to the door lock mechanism 1; the central control body 4 is electrically connected to the first door lock actuator 2 to enable the door lock mechanism 1 to realize an unlocking or locking action in a first state; or the central control body 4 is electrically connected to the second door lock actuator 3 to enable the door lock mechanism 1 to realize an unlocking or locking action in a second state; wherein the first state is a case where the central control body 4 detects that the vehicle speed is less than or equal to a first speed threshold X, and the second state is a case where the central control body 4 detects that the vehicle speed is greater than the first speed threshold X.

[0050] It can be understood that the first door lock actuator 2 is connected to the door lock mechanism 1 for realizing a locking or unlocking action of the door lock mechanism 1 according to the control of the central control body 4 when the vehicle speed is less than or equal to the first speed threshold. The second door lock actuator 3 is also connected to the door lock mechanism 1 for realizing a locking or unlocking action of the door lock mechanism 1 according to the control of the central control body 4 when the vehicle speed is greater than the first speed threshold. The central control body 4 is electrically connected to the first door lock actuator 2 and the second door lock actuator 3 for detecting the vehicle speed and controlling the corresponding door lock actuator action according to the vehicle speed. In this way, the central control body 4 can automatically adjust the door lock state according to the change of the vehicle speed, reflecting the development trend of vehicle intelligence. This intelligent control not only improves the convenience of operation, but also enhances the driving experience and safety. For example, by automatically locking the vehicle door through the central control system, the risk of accidents (such as collision) caused by accidental opening of the vehicle door during driving can be prevented, such as passengers being thrown out of the vehicle or falling on uneven road surfaces. In addition, automatic door locking also increases the anti-theft function, making it more difficult for illegal intrusion.

[0051] Therefore, the door lock control device provided by the present application improves the flexibility and safety of door lock control by setting the first door lock actuator 2 and the second door lock actuator 3 and automatically switching the control mode according to the vehicle speed and other conditions, and can ensure that the central control body 4 does not mistakenly unlock the door lock mechanism 1 under normal circumstances. In an emergency situation, such as when the vehicle collides, the central control body 4 instantaneously cuts off the power supply of the door lock mechanism 1, and the lock mechanism can still respond quickly to realize automatic unlocking of the door lock, ensuring the safety of the passengers' escape. In addition, the door lock control device can also avoid the problem of premature unlocking when a vehicle collision has not occurred.

[0052] In addition, the driver adjusts the parameters of these systems according to his own needs, such as the locking speed threshold, the automatic unlocking condition, etc. In this way, personalized settings can better adapt to the usage habits and safety requirements of different users.

[0053] In some embodiments, the door lock mechanism 1 is used to realize the locking and unlocking actions of the door lock, and the structure thereof is as shown in Figure 1 The first mounting plate 11 is provided with a lock slot 111, and the locking member 12 can be inserted into the lock slot 111 to realize the locking action. One end of the elastic member 13 is connected with the locking member 12, and the other end is fixedly connected with the second mounting plate 14, and is used to push the locking member 12 out of the lock slot 111 when unlocking.

[0054] For example, the door lock mechanism 1 is installed on the door of a vehicle, and the door lock mechanism 1 can be referred to as a central lock. The door lock mechanism 1 can be connected with a lock body on the door. Generally, after the lock tongue of the lock body of the door is clamped into the clamping groove of the vehicle body, the unlocking or locking action of the door lock mechanism 1 can be realized through the control of the central control body 4.

[0055] In some embodiments, the first door lock execution mechanism 2 includes a driving member 21, and the driving member 21 is electrically connected with the central control body 4. In the first state, the central control body 4 controls the driving member 21 to start, so as to realize the locking action of the door lock mechanism 1. Alternatively, the central control body 4 controls the driving member 21 to stop, so as to realize the unlocking action of the door lock mechanism 1.

[0056] It can be understood that when the vehicle speed is reduced to below a certain threshold, the central control body 4 will automatically unlock the door, so that the passenger can conveniently get on and off the vehicle, especially in parking lots, gas stations and other places where the door needs to be frequently opened and closed.

[0057] In some embodiments, the first door lock execution mechanism 2 can further include a first transmission member 22 connected between the driving member 21 and the door lock mechanism 1. In the first state, the central control body 4 controls the driving member 21 to start, and drives the first transmission member 22 to rotate through the driving member 21, so as to realize the locking action of the door lock mechanism 1. Alternatively, the central control body 4 controls the driving member 21 to stop driving, so as to realize the unlocking action of the door lock mechanism 1.

[0058] It can be understood that the driving member 21 is electrically connected with the central control body 4, and is used to start or stop under the control of the central control body 4. The first transmission member 22 is connected between the driving member 21 and the door lock mechanism 1, and is used to rotate under the driving of the driving member 21, so as to push the locking member 12 into the lock slot 111, thereby realizing the locking action of the door lock mechanism 1. When the driving member 21 is powered off, the driving member 21 stops driving, the first transmission member 22 stops rotating, at this time, the elastic member 13 which is stretched restores the deformation and resets, and drives the locking member 12 to disengage from the lock slot 111, thereby realizing the unlocking action of the door lock mechanism 1. In this way, the time of door lock operation can be reduced, and the overall efficiency of the system can be improved.

[0059] The driving member 21 can include, but is not limited to, a motor, which can provide precise rotation control, and the rotation speed and direction can be controlled by adjusting the current or voltage, so that the locking and unlocking actions of the door lock mechanism 1 are more accurate and controllable. The first transmission member 22 can include, but is not limited to, at least one rotating shaft, which can effectively transmit the rotating motion of the motor to the door lock mechanism 1 as the first transmission member 22. The rotating shaft is usually designed to have high mechanical efficiency, which can reduce energy loss and improve the overall efficiency of the system.

[0060] In some embodiments, the second door lock execution mechanism 3 includes an electromagnetic structure 31 and a permanent magnet structure 32. The electromagnetic structure 31 is electrically connected to the hollow main body; one end of the permanent magnet structure 32 is connected to the door lock mechanism 1; in the second state, the central control main body 4 controls the electromagnetic structure 31 and the permanent magnet structure 32 to be connected to realize the locking action of the door lock mechanism 1; or the central control main body 4 controls the electromagnetic structure 31 and the permanent magnet structure 32 to be disconnected to realize the unlocking action of the door lock mechanism 1.

[0061] It can be understood that under the control of the central control main body 4, the electromagnetic structure 31 is powered to generate a magnetic force to attract the permanent magnet structure 32, so that the permanent magnet structure 32 pushes the locking member 12 to be clamped into the lock groove 111 through the second transmission member 33, thereby realizing the locking action of the door lock mechanism 1. When the electromagnetic structure 31 is powered off, the magnetic force disappears, the electromagnetic structure 31 and the permanent magnet structure 32 move away from each other, the second transmission member 33 has no external force traction, at this time, the elastic member 13 stretched recovers the deformation and resets, and drives the locking member 12 to be separated from the lock groove 111, thereby realizing the unlocking action of the door lock mechanism 1.

[0062] Since the electromagnetic structure 31 can quickly respond to the instructions of the central control main body 4, the connection or disconnection of the electromagnetic structure 31 and the permanent magnet structure 32 is realized, thereby quickly executing the locking or unlocking action. For example, when the vehicle is in an accident or the like, under the control of the central control main body 4, the central control main body 4 can accurately control the electromagnetic structure 31 and the permanent magnet structure 32 in the second door lock execution mechanism 3 to be quickly disconnected, so that the passengers can safely escape. Or, after the vehicle is started and the door is automatically closed, the central control main body 4 can accurately control the connection of the electromagnetic structure 31 and the permanent magnet structure 32 in the second door lock execution mechanism 3, to prevent the safety hazard caused by accidentally opening the door during driving.

[0063] The electromagnetic structure 31 includes, but is not limited to, an electromagnetic coil, and the permanent magnet structure 32 includes, but is not limited to, a permanent magnet.

[0064] In some embodiments, the second door lock actuator 3 further comprises a second transmission member 33 connected between the permanent magnetic structure 32 and the door lock mechanism 1; in the second state, the central control body 4 controls the electromagnetic structure 31 and the permanent magnetic structure 32 to be connected, and drives the second transmission member 33 to rotate through the permanent magnetic structure 32 to realize the locking action of the door lock mechanism 1; or, the central control body 4 controls the electromagnetic structure 31 and the permanent magnetic structure 32 to be disconnected to realize the unlocking action of the door lock mechanism 1.

[0065] It can be understood that the electromagnetic structure 31 is electrically connected with the central control body 4, and the door lock mechanism 1 is connected with the permanent magnetic structure 32 through the second transmission member 33. Under the control of the central control body 4, the electromagnetic structure 31 is powered to generate a magnetic force to attract the permanent magnetic structure 32, so that the permanent magnetic structure 32 drives the locking member 12 to realize the locking action of the door lock mechanism 1 through the second transmission member 33. Therefore, the second transmission member 33 can make the permanent magnetic structure 32 more accurately transmit the movement to the door lock mechanism 1. When the electromagnetic structure 31 is powered off, the magnetic force disappears, the elastic member 13 stretched recovers the deformation and resets, and drives the locking member 12 to disengage from the locking groove 111, and the permanent magnetic structure 32 also resets under the action of the elastic member 13, thereby realizing the unlocking action of the door lock mechanism 1. Therefore, by controlling the connection and disconnection of the electromagnetic structure 31, the central control body 4 can accurately control the locking and unlocking actions of the door lock.

[0066] In some embodiments, after the central control body 4 inputs the first calibrated power-on current to the electromagnetic structure 31, an attractive force exists between the electromagnetic structure 31 and the permanent magnetic structure 32. In the case that the maximum distance exists between the electromagnetic structure 31 and the permanent magnetic structure 32, the attractive force between the electromagnetic structure 31 and the permanent magnetic structure 32 is the smallest, and the distance between the electromagnetic structure 31 and the permanent magnetic structure 32 is the largest. At this time, the magnetic force of the electromagnetic structure 31 disappears, the elastic member 13 stretched recovers the deformation and resets, and drives the locking member 12 to disengage from the locking groove 111, and the permanent magnetic structure 32 also resets under the action of the elastic member 13, thereby realizing the unlocking action of the door lock mechanism 1.

[0067] In some embodiments, after the central control body 4 inputs the second power-on calibrated current to the electromagnetic structure 31, a repulsive force exists between the electromagnetic structure 31 and the permanent magnetic structure 32. In the case that the minimum distance exists between the electromagnetic structure 31 and the permanent magnetic structure 32, the repulsive force between the electromagnetic structure 31 and the permanent magnetic structure 32 is smaller than the driving force or braking force of the driving member 21. At this time, it can prevent the leakage current at the electromagnetic structure 31 from affecting the normal work of the door lock mechanism 1 when the driving member 21 drives the door lock mechanism 1 to unlock or lock. That is, the residual magnetism in the electromagnetic structure 31 is eliminated, and the influence of the residual magnetism on the power-off unlocking of the door lock mechanism 1 when the vehicle collides is avoided. The direction of the first power-on calibrated current is opposite to the direction of the second power-on calibrated current.

[0068] In some embodiments, the central control body 4 is capable of controlling the door lock mechanism 1 to switch between the locking action in the first state and the locking action in the second state.

[0069] Exemplarily, in the second state, after the central control body 4 controls the electromagnetic structure 31 to be powered on for a time period T s, the central control body 4 controls the driving member 21 to stop, and the electromagnetic structure 31 and the permanent magnetic structure 32 are connected to each other, so that the locking action of the door lock mechanism 1 in the first state is switched to the locking action in the second state.

[0070] It can be understood that, during the driving of the vehicle, the central control body 4 detects the vehicle speed in real time and controls the corresponding door lock mechanism 1 to perform the action according to the vehicle speed. The central control body 4 is capable of controlling the door lock mechanism 1 to switch from the locking action in the first state to the locking action in the second state. For example, when the vehicle speed suddenly increases to P Km / h (for example, 70 Km / h) or more, that is, the vehicle speed exceeds the first speed threshold X, the central control body 4 powers on the electromagnetic structure 31 to generate electromagnetic attraction, and the electromagnetic structure 31 and the permanent magnetic structure 32 are attracted to each other, so as to realize the locking action of the door lock mechanism 1. After the electromagnetic structure 31 is powered on for a time period T s, where T > 0, the central control body 4 controls the control foot of the driving member 21 to be floating, so that the door lock control device is replaced by the electromagnetic attraction to keep the locking action of the door lock mechanism 1 by the driving force or the braking force of the driving member 21.

[0071] Exemplarily, when the central control body 4 detects that the vehicle speed decreases from the first speed threshold X to the second speed threshold Y, that is, (0 < Y < X), the central control body 4 controls the driving member 21 to start, and drives the first transmission member 22 to rotate through the driving member 21, so as to switch the locking action of the door lock mechanism 1 from the second state to the first state.

[0072] It can be understood that, during the driving of the vehicle, the central control body 4 detects the vehicle speed in real time and controls the corresponding door lock mechanism 1 to perform the action according to the vehicle speed. The central control body 4 is capable of controlling the door lock mechanism 1 to switch from the locking action in the first state to the locking action in the second state. For example, when the vehicle speed suddenly increases to P Km / h (for example, 70 Km / h) or more, that is, the vehicle speed exceeds the first speed threshold X, the central control body 4 powers on the electromagnetic structure 31 to generate electromagnetic attraction, and the electromagnetic structure 31 and the permanent magnetic structure 32 are attracted to each other, so as to realize the locking action of the door lock mechanism 1. After the electromagnetic structure 31 is powered on for a time period T s, where T > 0, the central control body 4 controls the control foot of the driving member 21 to be floating, so that the door lock control device is replaced by the electromagnetic attraction to keep the locking action of the door lock mechanism 1 by the driving force or the braking force of the driving member 21.

[0073] Exemplarily, in the second state and in the case that the vehicle is in collision during driving, the central control body 4 controls the electromagnetic structure 31 and the permanent magnetic structure 32 to be disconnected, so as to realize the unlocking action of the door lock mechanism 1.

[0074] It can be understood that, in the case that the vehicle speed is greater than the first speed threshold X and the vehicle is in collision, the central control body 4 or the door lock mechanism 1 is powered off, the power supply current of the electromagnetic structure 31 is cut off, and the restoring force of the elastic member 13 can pull the locking member 12 out of the lock groove 111, thereby realizing the unlocking action of the door lock mechanism 1. Alternatively, in the case that the vehicle speed is greater than the first speed threshold X and the vehicle is in collision, the door lock end mechanism is not powered off, and the central control body 4 outputs a reverse current at both ends of the electromagnetic structure 31, thereby realizing the unlocking action of the door lock mechanism 1.

[0075] In some embodiments, in the case that the vehicle speed is less than or equal to the first speed threshold X, the central control body 4 controls the driving member 21 to drive the first transmission member 22 to rotate, which is driven by the driving member 21 to push the locking member 12 to be clamped into the lock groove 111, thereby realizing the locking action of the door lock mechanism 1. When the driving member 21 is powered off, the driving member 21 stops driving, the first transmission member 22 stops rotating, at this time, the stretched elastic member 13 restores the deformation and resets, and drives the locking member 12 to be separated from the lock groove 111, thereby realizing the unlocking action of the door lock mechanism 1. In this case, the central control body 4 does not supply power to the electromagnetic structure 31, and the electromagnetic structure 31 does not generate electromagnetic attraction, that is, the door lock control device makes the door lock mechanism 1 in the locking state by the driving force or the braking force of the driving member 21.

[0076] The first threshold X and the second threshold Y described above can be set according to the vehicle calibration result, which is not particularly limited here. The calibration result generally refers to the value or data obtained in the calibration process.

[0077] The central control body 4 described above can include a speed detection instrument, a door lock switch button, but is not limited thereto.

[0078] The present application provides a door lock control method, Figure 2 The present application provides a door lock control method,

[0079] Please refer to Figure 1 and Figure 2 The present application also provides a door lock control method, comprising the following steps:

[0080] In the first state, the central control body 4 is electrically connected to the first door lock execution mechanism 2, so that the door lock mechanism 1 realizes the unlocking or locking action; or in the second state, the central control body 4 is electrically connected to the second door lock execution mechanism 3, so that the door lock mechanism 1 realizes the unlocking or locking action; wherein the first state is the case that the central control body 4 detects that the vehicle speed is less than or equal to the first speed threshold X, and the second state is the case that the central control body 4 detects that the vehicle speed is greater than the first speed threshold X.

[0081] It can be understood that, based on the driving speed of the vehicle, the central control body 4 is selectively electrically connected to the first door lock actuator 2 or the second door lock actuator 3, so that the door lock mechanism 1 realizes the unlocking or locking action in different modes.

[0082] Exemplarily, under the control of the central control body 4, the electromagnetic structure 31 is powered to generate a magnetic force to attract the permanent magnetic structure 32, so that the permanent magnetic structure 32 pushes the locking piece 12 into the lock slot 111 through the second transmission member 33, thereby realizing the locking action of the door lock mechanism 1. When the electromagnetic structure 31 is powered off, the magnetic force disappears, the electromagnetic structure 31 and the permanent magnetic structure 32 are away from each other, the second transmission member 33 is not externally pulled, at this time, the stretched elastic member 13 restores the deformation and resets, and drives the locking piece 12 to be separated from the lock slot 111, thereby realizing the unlocking action of the door lock mechanism 1.

[0083] Exemplarily, under the control of the central control body 4, the electromagnetic structure 31 is powered to generate a magnetic force to attract the permanent magnetic structure 32, so that the permanent magnetic structure 32 pushes the locking piece 12 to realize the locking action of the door lock mechanism 1 through the second transmission member 33. Therefore, the second transmission member 33 can make the permanent magnetic structure 32 more accurately transmit the movement to the door lock mechanism 1. When the electromagnetic structure 31 is powered off, the magnetic force disappears, the stretched elastic member 13 restores the deformation and resets, and drives the locking piece 12 to be separated from the lock slot 111, and the permanent magnetic structure 32 also resets under the action of the elastic member 13, thereby realizing the unlocking action of the door lock mechanism 1. Therefore, by controlling the connection and disconnection of the electromagnetic structure 31, the central control body 4 can accurately control the locking and unlocking actions of the door lock.

[0084] In some embodiments, the door lock control method further comprises that the central control body 4 can control the door lock mechanism 1 to switch between the locking action in the first state and the locking action in the second state.

[0085] In the second state, after the central control body 4 controls the electromagnetic structure 31 to be powered for T s, the central control body 4 controls the driving member 21 to stop, and the electromagnetic structure 31 and the permanent magnetic structure 32 are connected, so that the locking action of the door lock mechanism 1 in the first state is switched to the locking action in the second state.

[0086] It can be understood that the vehicle in the process of driving, the central control body 4 real-time detection of vehicle speed and according to the speed control corresponding door lock mechanism 1 execution action. Central control body 4 can control the door lock mechanism 1 in the first state of the locking action switch to the second state of the locking action. For example, the vehicle speed suddenly speed up to P Km / h (for example 70 Km / h) above, that is, the speed exceeds the first speed threshold X, the central control body 4 to electromagnetic structure 31 power, generate electromagnetic attraction, and with permanent magnet structure 32 mutual attraction, so as to realize the locking action of door lock mechanism 1, in electromagnetic structure 31 power T s, wherein T > 0, the central control body 4 control driving piece 21 control foot floating, so that the door lock control device by electromagnetic force instead of driving force or braking force of driving piece 21 to keep the locking action of door lock mechanism 1.

[0087] The central control body 4 detects the speed from the first speed threshold X to the second speed threshold Y, the case, the central control body 4 control driving piece 21 start, and through the driving piece 21 drive first transmission 22 rotation, so that the door lock mechanism 1 in the second state of the locking action switch to the first state of the locking action.

[0088] It can be understood that the vehicle in the process of driving, the central control body 4 drive real-time detection of vehicle speed and according to the speed control corresponding door lock mechanism 1 execution action. Central control body 4 can control the door lock mechanism 1 in the second state of the locking action switch to the first state of the locking action. Central control body 4 control driving piece 21 start, so that the locking piece 12 is still inserted in the lock slot 111, driving piece 21 drive M s, wherein M > 0, the controller to electromagnetic structure 31 both ends output reverse current, at this time, the magnetic force of electromagnetic structure 31 disappears, electromagnetic structure 31 and permanent magnet structure 32 away from each other, the second transmission 33 no external force traction, so that the door lock control device by driving force or braking force of driving piece 21 instead of electromagnetic force to keep the locking action of door lock mechanism 1.

[0089] In the second state and the vehicle in the process of driving collision, the central control body 4 control electromagnetic structure 31 and permanent magnet structure 32 disconnect, in order to realize the unlocking action of door lock mechanism 1.

[0090] It can be understood that, in the case of vehicle speed greater than the first speed threshold X, and the vehicle collision, the central control body 4 or door lock mechanism 1 power off, the power supply current of electromagnetic structure 31 is cut off, the restoring force of elastic piece 13 can be pulled out from the locking piece 12 in the lock slot 111, so as to realize the unlocking action of door lock mechanism 1. Or, in the case of vehicle speed greater than the first speed threshold X, and the vehicle collision, the door lock end mechanism does not occur power off, the central control body 4 in the two ends of electromagnetic structure 31 output reverse current, so as to realize the unlocking action of door lock mechanism 1.
