[0036] The electric working principle is as follows: the motor 4 is electrified to drive the first full gear 41 to rotate, the first full gear 41 drives the driven half gear 42 to rotate, the driven half gear 42 drives the A driving shaft 3A to rotate, the A driving shaft 3A drives the eccentric mechanism 31 to rotate counterclockwise, the eccentric mechanism 31 drives the outer pull plate 21, the inner end of the outer pull plate 21 drives the moving part of the lock body 7 to complete the opening and closing action (locking and unlocking) relative to the fixed part of the lock body 7, the motor 4 rotates in the positive and negative directions, the lock body 7 is controlled to complete the locking and unlocking through the above series of transmission relationships, and the motor 4 rotates in the positive and negative directions by an angle, the lock body 7 is controlled to complete the locking degree through the above series of transmission relationships, for example, when the motor rotates by 45 degrees in the positive and negative directions, the lock body is controlled to complete half locking or half unlocking through the above series of transmission relationships, and for example, when the motor rotates by 90 degrees in the positive and negative directions, the lock body is controlled to complete full opening or full locking through the above series of transmission relationships.

[0037] The outer pulling principle: when the lock body 7 is adjusted to half or full lock by the above-mentioned electric adjustment, the outer pulling plate 21 is manually operated to rotate inward, and the outer pulling plate 21 is in extrusion contact with the action part of the lock body 7 at one end, forcing the action part of the lock body to complete the unlocking.

[0038] The inner pulling principle: when the lock body is finally adjusted to half or full lock by the above-mentioned electric driving, the inner pulling plate 22 is manually operated to rotate downward, and the outer pulling plate 21 and the trigger driving plate are used to drive the A driving shaft 3A to rotate, the eccentric mechanism 3 is driven by the A driving shaft 3A to rotate clockwise, the outer pulling plate 21 is driven by the eccentric mechanism 31, and the inner end of the outer pulling plate 21 drives the action part of the lock body 7 to complete the unlocking relative to the fixed part of the lock body 7.

[0039] The operation principle of the hand unlocking core 23: when the lock body 7 is finally adjusted to half or full lock by the above-mentioned electric driving, the hand unlocking core 23 in the lock hole 105 is turned clockwise, the manual pull arm 242 of the connecting rod mechanism 24 is linearly moved by the inner end of the hand unlocking core 23, the driving half gear 243 at the inner end of the manual pull arm 242 meshes with the gear to rotate, the B driving shaft 3B is driven by the gear to rotate, and the action part of the lock body 7 at the bottom end of the B driving shaft 3B can also complete the unlocking.

[0040] Through the innovative double drive shaft (A / B shaft) + eccentric mechanism + gear transmission topology, the four function modules of electric drive, outer opening, inner opening and hand opening lock core 23 are integrated in a single compact shell 1, and the highly integrated structure design breaks through the space limitation: through the innovative double drive shaft (A / B shaft) + eccentric mechanism + half gear transmission topology, the four function modules of electric drive, outer opening, inner opening and hand opening lock core 23 are integrated in a single compact shell 1, saving space. The engagement design of the driven half gear 42 and the first full gear 41 saves space compared with the traditional full gear set; the lock body 7 is placed at the bottom of the shell 1, and the gear structure and the connecting rod mechanism 24 are arranged in the vertical direction, realizing efficient use of three-dimensional space, reducing the overall volume compared with the traditional scheme, and perfectly adapting to the ultra-thin car door. Moreover, the innovative establishment of the electric drive → manual → mechanical emergency failure degradation path ensures that the lock can be unlocked under any working condition. First, electric priority: the motor 4 drives the half gear through the first full gear transmission, and the half gear drives the drive shaft to rotate, and the drive shaft drives the precise transmission chain of the eccentric mechanism, and drives the lock body to realize ±45° (half lock) and ±90° (full lock) angle control. When the electric drive fails, the hand opening lock core 23 drives the B drive shaft to rotate through the driving half gear of the connecting rod mechanism, and the B drive shaft can be unlocked through single-stage transmission, improving transmission efficiency. Moreover, the multi-station opening mode can still be used normally when other stations fail, reducing the probability of disassembly and maintenance, improving the service life, and providing multiple stations for opening when the lock is locked, with high safety.

[0041] In another embodiment, the outer opening panel 21 is pivoted inside the outer shell 1, the outer shell 1 is provided with an outer slot 101 for manual operation of the outer opening panel 21, a sliding carriage 102 is installed in the outer shell 1, the sliding carriage 102 is provided with a sliding channel, the eccentric mechanism 31 includes a wheel disc 311 provided on the A drive shaft 3A, an eccentric seat 312 installed on the wheel disc 311, and a sliding arm 313 fitted on the sliding carriage 102 through the sliding channel, the outer opening panel 21 is provided with three angle claws 211, the first angle claw 211 extends into the outer slot 101, the second angle claw 211 extends to the sliding path of the sliding arm 313 and is provided with a pulling opening 212, the third angle claw 211 is provided with a hooking part 213 and is connected with the outer shell 1 through a first torsion spring 214, so that the outer opening panel 21 is self-locked in the rotating angular position, the other end of the sliding arm 313 away from the second angle claw 211 enters the bottom end of the wheel disc 311 and is movably connected with the eccentric seat 312. When the motor 4 is powered on to drive the first full gear 41 to rotate, the first full gear 41 engages the driven half gear 42 to rotate, and the A drive shaft 3A is driven to rotate by the driven half gear 42, the A drive shaft 3A drives the wheel disc 311 to rotate, the wheel disc 311 drives the eccentric seat 312 to rotate, and when the eccentric seat 312 rotates to contact the inner end of the sliding arm 313, the sliding arm 313 is driven to move linearly on the sliding carriage 102, for example, when the sliding arm 313 moves towards the outer opening panel 21, the moving part of the lock body 7 is closed (half-locked or fully-locked) with the fixed part of the lock body, when fully-locked (the linear stroke of the sliding arm 313 is larger), the outer end of the sliding arm 313 touches the opening part 212 of the second angle claw 211, causing the outer opening panel 21 to rotate counterclockwise, and the third angle claw 211 tightens the first torsion spring 214; conversely, when the motor 4 reverses rotation, the sliding arm 313 moves in the opposite direction away from the outer opening panel 21, the moving part of the lock body 7 is separated (unlocked or half-unlocked) relative to the fixed part of the lock body 7, when fully-unlocked (the reverse linear stroke of the sliding arm 313 is larger), the outer end of the sliding arm 313 is separated from the opening part 212 of the second angle claw 211, the third angle claw 211 relaxes and returns, and the outer opening panel 21 is caused to rotate counterclockwise by dragging. When fully-locked, the outer end of the sliding arm 313 touches the opening part 212 of the second angle claw 211, which forms a limiting condition, so that the operator operates the first angle claw 211 (external operation) from the outer slot 101, causing the outer opening panel 21 to rotate clockwise, at this time the opening part 212 pushes away the limiting force of the outer end of the sliding arm 313, forcing the sliding arm 313 to reverse and retract, the sliding arm 313 reversely pushes the eccentric seat 312 to rotate clockwise, and the wheel disc 311 is driven by the eccentric seat 312 to rotate clockwise, thereby removing the limitation and completing the external operation unlocking mode.

[0042] In another embodiment, the inner opening release plate 22 is connected to the outer shell 1, the end side of the outer shell 1 is provided with an inner notch, one end of the inner opening release plate 22 extends to the inner notch, and the other end extends to one end of the driving plate and is provided with an arc-shaped trigger portion between the other end of the driving plate and the one end of the driving plate. The other end of the driving plate is drivingly connected to the lock body. The driving plate is similar to the sliding arm 313 in the outer opening, and is a bridge component for driving the movable part and the fixed part of the lock body 7 to separate (outer opening lock) when the inner opening is operated. When the inner opening is operated, the inner opening release plate 22 is deflected downward with one end of the arc-shaped trigger portion to contact the driving plate and trigger the driving plate to rotate, and the movable part of the lock body 7 is separated from the fixed part (inner opening lock) by the driving plate. The driving plate is provided with a second torsion spring 321 between the driving plate and the connecting portion of the outer shell 1. When the inner opening release plate 22 is reversely operated and reversely deflected upward, the arc-shaped trigger portion of the inner opening release plate 22 is separated from the driving plate, the second torsion spring 321 is contracted and reversely pulls the driving plate to reset.

[0043] In another embodiment, the outer shell 1 further comprises a circuit board 5, and the circuit board 5 is provided with a control module 6, the control module 6 is electrically connected to the motor 4, and the control module 6 is divided into three units, which include a first attitude sensor 61 arranged relative to the outer opening release plate 21 (outer opening), a second attitude sensor 63 arranged relative to the inner opening release plate 22 (inner opening), and a second attitude sensor 63 arranged relative to the hand opening lock core 23 (lock core opening). When the outer opening release plate 21 (outer opening) is used to open the lock, the first attitude sensor 61 sends a signal to the motor 4, and the motor 4 is reversely rotated to intelligently open the lock body 7; when the inner opening release plate 22 (inner opening) is used to open the lock, the signal interface 62 sends a signal to the motor 4, and the motor 4 is reversely rotated to intelligently open the lock body 7; similarly, when the hand opening lock core 23 is used to open the lock, the second attitude sensor 63 sends a signal to the motor 4, and the motor 4 is reversely rotated to intelligently open the lock body 7. The three hand opening modes can trigger the motor 4 to convert from the locking mode to the opening mode, thereby improving the opening efficiency.

[0044] Specifically: the first attitude sensor 61, the sensing end and the movement trajectory of the outer opening movable plate 21 are opposite, the sensing end and the movement trajectory of the inner opening movable plate 22 are opposite, for detecting the displacement of the inner opening movable plate 22 and generating an inner opening trigger signal, for detecting the displacement of the outer opening movable plate 21 and generating an outer opening trigger signal; the second attitude sensor 63, the sensing end and the rotating part of the hand opening lock core 23 are opposite, for detecting the rotation angle of the hand opening lock core 23 and generating a hand emergency signal; and the circuit board 5 is configured to: when the first attitude sensor 61 outputs the trigger signal, the motor 4 is driven to rotate in a preset direction, and the lock body 7 is unlocked through the A driving shaft 3A and the driven half gear 42; when the second attitude sensor 63 outputs the hand emergency signal, the power supply circuit of the motor 4 is forcibly cut off, so that the hand opening lock core 23 drives the lock body 7 to unlock through the B driving shaft 3B and the connecting rod mechanism 24; when the lock is completely locked, the external third party remote control device makes the motor 4 lock the angle (full lock ± 90° (full lock) angle control), and the anti-theft function is realized.

[0045] It should be further pointed out that the lock body 7 mentioned in the application is a prior art of intelligent lock, which will be locked when the trigger condition occurs, and will be unlocked when the trigger condition disappears. The opening and closing principle of the lock is a prior art, and will not be described again. However, through the integration of mechanical structure, the application realizes a functional improvement, and it is possible to realize the interference between actions through the motor 4 control structure: therefore, on this basis, the application also proposes an optimal scheme of configuring a motor execution information base according to priority selection, so as to cope with emergency situations or meet the personalized use needs of users.

[0046] The control module is configured with a configuration strategy and a control strategy, and the configuration strategy includes:

[0047] Step S1, obtain the current state until the preset standard condition is met, enter step S2; the standard condition includes an attitude standard condition and a control standard condition, the attitude standard condition is configured to obtain the state information of the first attitude sensor and the state information of the second attitude sensor until the preset attitude information reference is met; the control standard condition is to obtain the corresponding configuration permission instruction from the signal interface. First, there are two ways to enter the configuration step, but the permissions can be configured differently, that is, the use range of the priority label corresponding to the configuration step is different, and theoretically the configuration using the priority label range is wider through attitude detection, and if the configuration condition is not met, the control module will not perform the next action.

[0048] Step S2, obtain the state information of the first attitude sensor until the corresponding configuration action is matched in the action matching library; then obtain the attitude of the two action parts through the first attitude sensor, and the attitude needs to be matched to the corresponding attitude in the action matching library. The action matching library is pre-constructed, for example, for a specific rotation angle and a specific touch method, such as long pressing and continuous point touching, which can be configuration actions in the action matching library. However, it should be noted that the action cannot conflict with the existing basic action, that is, the basic action of opening and closing the door cannot be configured again to avoid logical conflicts. The second thing is that the action must meet the identifiable standard, for example, the action of touching twice is not set with other touch actions. In this way, different actions can be prioritized according to the user's usage habits, and the priority tags determine the action feedback in different scenarios.

[0049] Step S3, configure the priority tag of the corresponding configuration action according to the state information of the second attitude sensor. The second attitude sensor configures different priority tags by manually rotating, for example, setting the priority to the highest, or setting the priority to the lowest, or setting the priority to the emergency situation, etc. The priority can also be set according to other feedback signals. With more information that can be monitored by new energy vehicles, the priority tags can also be more.

[0050] Step S4, configure the configuration action and the corresponding priority tag in the motor execution information library. In this way, the priority of a certain action corresponding to a specific scene is set, so that the handle side will receive instructions when the action is executed. It should be noted that this priority relationship is not sent after the data processing of the car terminal, so it does not depend on the communication of the car terminal. The advantage of this is that after the configuration is completed, the problem of abnormal door lock function caused by communication, data processing or damage of the car terminal itself is avoided. At the same time, the user's adaptability demand is met, because when a dangerous situation occurs, such as waterlogging of the car, the terminal itself cannot complete the underwater judgment, communication and other actions. At this time, through the judgment of the waterlogging situation, the handle of the back seat can also complete the function of auxiliary opening of the door through the motor, so in an emergency, independent data processing and logical judgment ability is particularly important for the car door handle.

[0051] Step S5, return to step S1;

[0052] The control strategy comprises:

[0053] Step A1, obtaining the current state information of the first attitude sensor to match the corresponding priority label from the motor execution library; the corresponding priority label can be obtained through user action, and the priority label is executed according to the actual environment condition to execute the corresponding signal, that is, for example, the action of the first attitude sensor is to open the door, but the priority label shows that the door can only be opened under certain conditions, so this action will be ignored, on the contrary, if the priority label shows that the door opening action is always executed first, then the motor will assist the door opening in priority regardless of the state.

[0054] Step A2, obtaining the current environment feedback signal to generate state execution instructions according to the priority label, and the controller controls the motor to work in the target state according to the state execution instructions. For example, when there is a car near the door or a car approaching from the back, the door cannot be opened through the monitoring signal, but this will affect the operation comfort, and only children's families can make such design for safety, and this action can be realized through configuration, that is, the priority of the door opening action is reduced, that is, the door opening action is reduced to any opening risk, and then a new door opening action is configured to satisfy the comfort of adult door opening. Compared with the traditional child lock function, the scene is more abundant and reliable.

The essence is that the specific orientation of each component is according to its actual installation and actual use and the orientation description habit of those skilled in the art, and this is stated.

It should be understood that the above description is only a specific embodiment of the present application and does not limit the protection scope of the present application. It is particularly pointed out that any modification, equivalent replacement, improvement, etc. made by those skilled in the art within the spirit and principles of the present application should be included in the protection scope of the present application.
