[0026] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 11 The door lock 100 according to an embodiment of the present invention is described. The door lock 100 includes a driving mechanism 10 and a door lock device.

[0027] Specifically, the driving mechanism 10 includes a motor 11; the driving mechanism 10 cooperates with the door lock device, and the door lock device includes a central lock, an electric unlocking and a child lock. When the driving mechanism 10 is working, the motor 11 is suitable for driving at least one of the central lock, the electric unlocking and the child lock to switch between an open state and a closed state.

[0028] Optionally, in the present application, a motor 11 is provided in the door lock 100 to drive the opening and closing of the central lock or the opening and closing of the electric unlocking or the opening and closing of the child lock. For example, when the motor 11 rotates in a first direction, the central lock is used to move from the central lock closed position to the central lock open position to achieve the locking of the central lock. And after the central lock is in the central lock open position, the electric unlocking of the door lock 100 can be achieved, and the door lock 100 can be electrically closed and opened. When the motor 11 rotates in a second direction, the central lock is used to move from the central lock open position to the central lock closed position. Among them, the first direction is Figure 4 The second direction is clockwise. Figure 4 Counterclockwise direction.

[0029] According to the door lock 100 of the embodiment of the present invention, by setting a single motor 11 and coordinating the motor 11 with the central lock, the electric unlocking and the child lock, a single motor 11 can be used to control multiple locks and realize multiple functions, so that the system structure of the door lock 100 is more integrated, the structure of the door lock 100 is effectively simplified, the difficulty of designing and manufacturing the door lock 100 is reduced, the failure points are reduced, the reliability of the door lock 100 is improved, and the user's use risk is reduced. At the same time, since the number of motors 11 is reduced, the production cost is reduced, the maintenance convenience of the door lock 100 is improved, and it is conducive to large-scale production and application.

[0030] Optionally, when the motor 11 rotates in a first direction, the central lock is first switched to the open state, and then the electric unlock is switched to the open state; when the motor 11 rotates in a second direction opposite to the first direction, the central lock is switched to the closed state.

[0031] Thus, through the bidirectional rotation of the motor 11, when the motor 11 rotates in the first direction, the central control lock is opened, and then the electric unlocking is opened, thereby realizing the upper central control action of the door lock 100, that is, from the closed state to the open state and the electrolytic action. At this time, the central control lock is locked, and the electric unlocking can electrically open the door lock 100. When the motor 11 rotates in the second direction, the central control lock is closed and unlocked. At this time, all the car doors are unlocked at the same time.

[0032] Optionally, when the motor 11 rotates in the first direction, the child lock is switched to an on state; when the motor 11 rotates in the second direction, the child lock is switched to a off state.

[0033] Therefore, when the motor 11 rotates along the first direction, the central control lock is opened, the child lock is opened, and the central control action and the child lock action of the door lock 100 are completed, the central control is locked, and the child lock is locked. When the motor 11 rotates along the second direction, the central control lock is closed, and the child lock is closed. Through the two-way rotation of the motor 11, the child lock and the central control lock can be switched between the open state and the closed state.

[0034] According to some embodiments of the present invention, Figure 2-Figure 7 As shown, the central control lock includes: a central control crank 21, which cooperates with the driving mechanism 10, and the central control crank 21 can be switched between the central control lock open position and the central control lock closed position. When the driving mechanism 10 is working, the motor 11 is suitable for driving the central control crank 21 to switch between the central control lock open position and the central control lock closed position.

[0035] When the motor 11 rotates in the first direction, the motor 11 drives the central control crank 21 from the central lock closed position to the Figure 4The motor 11 rotates in the second direction to the central lock opening position. At this time, the central lock is opened. When the motor 11 rotates in the second direction, the motor 11 drives the central control crank 21 to rotate from the central lock opening position along the second direction to the central lock closing position. At this time, the central lock is closed and the user can open the car door.

[0036] Therefore, by cooperating with the central control crank 21 and the driving mechanism 10, the central control crank 21 can be switched between the central control lock open position and the central control lock closed position, thereby realizing flexible switching of the central control lock between the open state and the closed state, thereby improving the operating efficiency of the door lock 100.

[0037] Alternatively, if Figure 2-Figure 7 As shown, the electric unlocking comprises: an unlocking arm 31, which cooperates with the driving mechanism 10. When the central lock is in the open state, the driving mechanism 10 drives the unlocking arm 31 to move to realize the electrolysis function.

[0038] The vehicle further includes a locking structure 50, which is disposed on the vehicle body and includes a locking tongue 51 and a locking arm 52. The locking arm 52 can be engaged with or separated from the locking tongue 51 by the unlocking arm 31. Thus, when the central lock is in the open state, the driving mechanism 10 can drive the unlocking arm 31 to move, thereby realizing the direct opening and closing of the shielding control door electric unlocking of the mechanical structure.

[0039] Alternatively, if Figure 2-Figure 7 As shown, the door lock 100 further includes: an inside-outside unlocking device 60, which cooperates with the central control crank 21, and the inside-outside unlocking device 60 and the unlocking arm 31 are detachably cooperated. In the process of switching from the closed state of the central control lock to the open state of the central control lock, the central control crank 21 is suitable for driving the inside-outside unlocking device 60 to separate from the unlocking arm 31 to achieve the disconnection of the outside unlocking function and the disconnection of the inside unlocking function.

[0040] During the process of the motor 11 driving the central control crank 21 to move from the central control lock closed position to the central control lock open position, the central control crank 21 can drive the internal and external unlocking device 60 to move, so that the internal and external unlocking device 60 is separated from the first end on the unlocking arm 31, thereby realizing the disconnection of the external unlocking function, and the internal and external unlocking device 60 is separated from the second end on the unlocking arm 31, thereby realizing the disconnection of the internal unlocking function.

[0041] Therefore, the inside and outside unlocking device 60 and the unlocking arm 31 can be detachably matched, so that the door lock 100 can flexibly realize the disconnection of the outside unlocking function and the inside unlocking function, thereby improving the safety of the door lock 100 and avoiding misoperation.

[0042] According to some embodiments of the present invention, Figure 2-Figure 7As shown, the internal and external unlocking device 60 includes: an external opening arm 61 and an internal opening arm 62. The external opening arm 61 and the unlocking arm 31 can be detachably matched. When the external opening arm 61 and the unlocking arm 31 are matched, the external opening arm 61 is suitable for moving the unlocking arm 31 to realize the external unlocking function. When the external opening arm 61 and the unlocking arm 31 are separated, the external unlocking function is disconnected. That is, when the motor 11 drives the central control crank 21 to move from the central control lock opening position to the central control lock closing position, that is, the central control lock is in the closed state, when the external opening arm 61 and the first end of the unlocking arm 31 form a match, the external opening arm 61 can move the unlocking arm 31 to realize the external unlocking function. When the central control lock is in the opening state, the external opening arm 61 and the first end of the unlocking arm 31 are separated, the external unlocking function is disconnected.

[0043] The inner opening arm 62 and the unlocking arm 31 can be detachably matched. When the inner opening arm 62 and the unlocking arm 31 are matched, the inner opening arm 62 is suitable for moving the unlocking arm 31 to realize the inner opening unlocking function. When the inner opening arm 62 and the unlocking arm 31 are separated, the inner opening unlocking function is disconnected. When the motor 11 drives the central control crank 21 to move from the central control lock opening position to the central control lock closing position, that is, the central control lock is in the closed state, when the inner opening arm 62 and the second end of the unlocking arm 31 form a match, the inner opening arm 62 can move the unlocking arm 31 to realize the inner opening unlocking function. When the central control lock is in the opening state, the inner opening arm 62 and the second end of the unlocking arm 31 are separated, the inner opening unlocking function is disconnected.

[0044] Therefore, by the movement of the inner opening arm 62 and the outer opening arm 61 and their respective detachable cooperation with the unlocking arm 31, the door lock 100 can flexibly realize the inner opening unlocking function and the outer opening unlocking function, as well as realize the disconnection of the outer opening unlocking function and the inner opening unlocking function, thereby improving operational efficiency and reliability.

[0045] According to some embodiments of the present invention, Figure 2-Figure 7As shown, the unlocking arm 31 is provided with an external unlocking portion 311 and an internal unlocking portion 312; the external opening arm 61 is provided with a slidable external opening clutch slider 611. When the external opening arm 61 cooperates with the unlocking arm 31, the external opening clutch slider 611 and the external unlocking portion 311 are stopped to move the unlocking arm 31. When the external opening clutch slider 611 is separated from the unlocking arm 31, the external opening arm 61 rotates without contacting the external unlocking portion 311, thereby realizing the disconnection of the external opening unlocking function. An external unlocking portion 311 is provided on the first end of the unlocking arm 31, and an internal unlocking portion 312 is provided on the second end of the unlocking arm 31. When the central lock is in a closed state, the external opening clutch slider 611 on the external opening arm 61 stops and moves the external unlocking portion 311 on the first end of the unlocking arm 31 to realize the external opening unlocking function; when the central lock is in an open state, the external opening clutch slider 611 on the external opening arm 61 is separated from the external unlocking portion 311 on the first end of the unlocking arm 31, and when the external opening arm 61 rotates, the external opening clutch slider 611 cannot move the unlocking arm 31, thereby realizing the disconnection of the external opening unlocking function.

[0046] The inner opening arm 62 is provided with a slidable inner opening clutch slider 621. When the inner opening arm 62 cooperates with the unlocking arm 31, the inner opening clutch slider 621 abuts against the inner unlocking portion 312 to move the unlocking arm 31. When the inner opening clutch slider 621 is separated from the unlocking arm 31, the inner opening arm 62 rotates without contacting the inner unlocking portion 312, thereby realizing the disconnection of the inner opening unlocking function. When the central control lock is in the closed state, the inner opening clutch slider 621 on the inner opening arm 62 abuts against the inner unlocking portion 312 on the second end of the unlocking arm 31 and moves the unlocking arm 31, thereby realizing the inner opening unlocking function; when the central control lock is in the open state, the inner opening clutch slider 621 on the inner opening arm 62 separates from the inner unlocking portion 312 on the second end of the unlocking arm 31, and when the inner opening arm 62 rotates, the inner opening clutch slider 621 cannot move the unlocking arm 31, thereby realizing the disconnection of the inner opening unlocking function.

[0047] Therefore, a slidable outer opening clutch slider 611 is provided on the outer opening arm 61, so that the outer opening unlocking function and the outer opening unlocking function can be realized and disconnected through the abutment and separation between the outer opening clutch slider 611 and the outer unlocking part 311, and a slidable inner opening clutch slider 621 is provided on the inner opening arm 62, so that the inner opening unlocking function and the inner opening unlocking function can be realized and disconnected through the abutment and separation between the inner opening clutch slider 621 and the inner unlocking part 312. The door lock 100 is used to realize inner opening and outer opening, which is conducive to the integrated design of the door lock 100 and reduces costs.

[0048] According to some embodiments of the present invention, Figure 2-Figure 7As shown, the central control lock further includes: a central control connecting rod 22, which is hinged to the central control crank 21. During the process of switching from the closed state of the central control lock to the open state of the central control lock, the central control connecting rod 22 is suitable for pushing the external opening clutch slider 611 to separate the external opening clutch slider 611 from the external unlocking part 311.

[0049] When the central lock moves from the central lock closed position to the central lock open position, the driving mechanism 10 drives the transmission member 74 along the Figure 4 The first matching portion 741 on the transmission member 74 moves the second matching portion 211 on the central control crank 21 so that the central control crank 21 moves along the first direction of the transmission member 74. Figure 4 The central control crank 21 is rotated in the second direction, and under the action of the central control crank switching spring 24, the central control crank 21 is kept in the central lock opening position. Similarly, when the central lock is in the central lock closing position, the central control crank switching spring 24 can keep the central control crank 21 in the central lock closing position. The central control crank 21 is hinged with a central control connecting rod 22, and the motor 11 can drive the central control connecting rod 22 to move through the central control crank 21. When the central lock is in the opening state, the central control crank 21 moves from the central lock closing position to the central control connecting rod 22. Figure 4 The central control crank 21 drives the central control connecting rod 22 to move in the second direction to the central control lock opening position. Figure 3 At this time, the central control link 22 pushes the outer opening clutch slider 611 on the outer opening arm 61 toward Figure 3 The outer clutch slider 611 is separated from the outer unlocking portion 311 by the right side movement, and the outer clutch slider 611 cannot move the unlocking arm 31 when the outer opening arm 61 rotates.

[0050] Therefore, by hingedly connecting the central control connecting rod 22 and the central control crank 21, it is convenient to drive the central control connecting rod 22 to move, thereby facilitating pushing the outer opening clutch slider 611 to realize the outer opening unlocking function.

[0051] According to some embodiments of the present invention, Figure 8 As shown, the door lock 100 further includes: an inner pulling device 12, which cooperates with the central control crank 21, and the inner pulling device 12 is pulled to move the central control crank 21 to the central lock closing position.

[0052] Optionally, in the present application, the door lock 100 can be used on a vehicle to open and close the door, and the inner pull device 12 can be provided on the door to open and close the door as a mechanical device. The inner pull device 12 cooperates with the central control crank 21. When the central control lock is in the open state, the user pulls the inner pull device 12 to drive the inner opening arm 62 to rotate. The inner opening arm 62 is provided with a third matching portion 622. The third matching portion 622 moves the fourth matching portion 212 on the central control crank 21 so that the central control crank 21 can rotate to the closed state of the central control lock. At this time, considering that the central control lock is in the open state, the child lock is also in the open state. When the user pulls the inner pull device 12 again, since the fifth matching portion 213 on the central control crank 21 can only drive the child lock crank 41 to move in one direction, the child lock will not change from the open state to the closed state, and the torque of the inner pull device 12 cannot be transmitted to the fifth matching portion 213 to realize the child lock unlocking in the closed state, and the inner opening clutch slider 621 remains in the position when the central control lock is in the open state. Therefore, since the child lock is in the open state, the inner pull device 12 is in the closed state and the door still cannot be opened.

[0053] Therefore, by setting the inner pulling device 12, the inner pulling device 12 can realize the central lock in the closed position through the central control crank 21, which is convenient for user operation, simplifies the operation procedure, increases the user experience, and reduces the safety risks caused by the user's misoperation of the inner pulling device 12 during driving.

[0054] That is, during the process of pulling the central control crank 21 of the inner pulling device 12 to be located at the central lock closing position, the child lock remains in the open state.

[0055] According to some embodiments of the present invention, Figure 2-Figure 7 As shown, the child lock includes: a child lock crank 41. In the process of switching from the closed state of the central lock to the open state of the central lock, the child lock crank 41 cooperates with the central control crank 21 to switch the child lock to the open state.

[0056] Specifically, when the central lock is in the central lock opening position, the child lock crank 41 cooperates with the convex part on the transmission member 74, and the convex part realizes the limiting of the child lock crank 41, and the child lock is in the opening state. When the central control crank 21 rotates, the third matching part 622 provided on the central control crank 21 drives the child lock crank 41 when it rotates in the direction toward the central lock opening position. Specifically, the third matching part 622 cooperates with the sixth matching part 411 on the child lock crank 41. When the motor 11 drives the transmission member 74 to rotate, the central control crank 21 is driven to move from the central control closing position to the central lock opening position, and the child lock crank 41 is rotated. Due to the action of the child lock crank switching spring 42, the child lock crank 41 is kept in the opening state. Among them, one end of the child lock crank switching spring 42 is connected to the child lock crank 41, and the other end is connected to the housing of the door lock 100. The child lock crank switching spring 42 is a torsion spring.

[0057] When the child lock is in the on state, the inner opening clutch slider 621 is pulled to the side away from the unlocking arm 31 and separated from the lock tongue 51, so that the inner opening unlocking function is disconnected, and the door cannot be opened by the unlocking arm 31.

[0058] The inner pull device 12 drives the inner opening arm 62 to rotate, and the inner opening arm 62 drives the central control crank 21 to rotate. At this time, the central control crank 21 rotates from the central lock open position to the central lock closed position. However, since the child lock crank 41 remains in the central lock open position when the inner pull device 12 is pulled, it is necessary to further judge through the control logic of the domain control. If the logic of the whole vehicle is the child lock open state before pulling the inner pull device 12, then after pulling the inner pull device 12, the child lock crank 41 remains in the central lock open position, which will cause the inner door to fail to open. When the central lock is in the central lock closed position, the door still cannot be opened. If the logic of the whole vehicle is the child lock closed state, then after the inner pull device 12 is pulled, the domain control of the whole vehicle will give the motor 11 an instruction to drive the motor 11 to unlock the child lock alone, that is, the child lock is changed from the open state to the closed state, and the child lock crank 41 is separated from the convex part on the transmission member 74 included in the drive motor 11. When the user pulls the inner pulling device 12 again, the inner pulling device 12 drives the inner opening arm 62 to rotate, and the inner opening arm 62 drives the unlocking arm 31 to unlock and open the door.

[0059] Therefore, the child lock crank 41 is set, when the central lock is in the central lock opening position, the child lock is in the opening state, the domain control recognizes the user's intention according to the opening state or closing state of the child lock, and when the domain control obtains the instruction that the child lock is in the closing state, the child lock is still in the opening state, and the inner pull device 12 is pulled once to realize that the central lock is in the central lock closing position, and the domain control controls the motor 11 to drive the child lock crank 41 to move so that the child lock is in the closing state. When the inner pull device 12 is pulled twice, the inner pull device 12 directly drives the inner opening arm 62 and the unlocking arm 31 to open the door, thereby increasing the safety of the vehicle and increasing protection. Therefore, the child lock function is realized by a single drive motor 11 combined with software control logic, and the child lock is opened and closed by the rotation of a single motor 11. On the basis of retaining the mechanical child lock structure, the child lock can only be released by the action of the motor 11, further ensuring the safety of the child lock.

[0060] like Figure 3 As shown, the driving mechanism 10 directly turns the central control crank 21 and the child lock crank 41 in the central control open state, so that the central control crank and the child lock crank 41 rotate counterclockwise in the direction shown in the figure to the central control closed state and the child lock closed state respectively, and the central control crank and the child lock crank 41 are separated from the driving mechanism 10. Figure 2 When the central lock is in the closed state and the child lock is in the closed state, the outer clutch slider 611 contacts the unlocking arm 31 under the action of the spring force and can move the unlocking arm 31. At this time, the matching protrusion 731 moves into the slide groove of the outer unlocking part 311 of the unlocking arm 31 under the movement of the unlocking arm 31, and the child lock crank 41 drives the inner clutch slider 621 to move to the state of abutting against the inner unlocking part 312 on the unlocking arm 31. At this time, both the inner and outer unlocking devices 60 can open and close the door.

[0061] According to some embodiments of the present invention, the door lock 100 further includes: a transmission mechanism, wherein the driving mechanism 10 cooperates with the door lock device through the transmission mechanism, and when the transmission mechanism transmits, the central control lock switches to an open state, and then the transmission mechanism resets, and when the transmission mechanism transmits again, the driving mechanism 10 drives the unlocking arm 31 to move through the transmission mechanism to realize the electrolysis function.

[0062] When the central lock is switched to the open state, the drive mechanism 10 drives the transmission mechanism to move for the first time, and the transmission structure does not drive the unlocking arm 31 to move. After the transmission mechanism completes the action of the central lock opening state, the transmission mechanism is reset. When the drive mechanism 10 drives the transmission mechanism to move again, at this time, the transmission mechanism drives the unlocking arm 31 to move and realizes the electrolysis function.

[0063] Therefore, by setting up a transmission mechanism, it is convenient to realize the electrolysis function and improve the safety of the door lock 100.

[0064] According to some embodiments of the present invention, Figure 6-Figure 8 As shown, a mating groove 32 is formed on the unlocking arm 31, and the mating groove 32 includes a first mating groove 33 and a second mating groove 34 that are connected to each other; the transmission mechanism includes a transmission arm 71, and a mating protrusion 731 is provided on the transmission arm 71, and the mating protrusion 731 is mated in the mating groove 32. When the central control lock is switched to the open state, the mating protrusion 731 can be movably mated in the first mating groove 33 and the unlocking arm 31 is in the electrically unlocked closed state. When the mating protrusion 731 is located in the second mating groove 34, the driving mechanism 10 is suitable for driving the unlocking arm 31 to move through the transmission arm 71.

[0065] The first matching groove 33 and the second matching groove 34 have different extension directions. When the central lock is switched to the open state, the driving mechanism 10 drives the transmission mechanism to rotate. The matching protrusion 731 on the transmission arm 71 is only arranged in the first matching groove 33 and forms a movable match with the first matching groove 33. The transmission structure does not drive the unlocking arm 31 to move. When the transmission mechanism is reset, the position of the central control link 22 changes, and the driving mechanism 10 drives the transmission mechanism to rotate. At this time, the matching protrusion 731 is located in the second matching groove 34. The second matching groove 34 can limit the matching protrusion 731. At this time, the transmission arm 71 drives the unlocking arm 31 to move and realize the electrolysis function. Therefore, by setting the matching groove 32 and the matching protrusion 731 is matched in the matching groove 32, the movement range of the matching protrusion 731 can be effectively limited, so as to facilitate the switching of the unlocking state of the unlocking arm 31.

[0066] Optionally, the mating protrusion 731 is a pin.

[0067] According to some embodiments of the present invention, Fig.10 and Fig.11 As shown, the door lock 100 further includes: a limit member 23, which is movably disposed at the matching groove 32. When the central control lock is switched to the open state, the limit member 23 separates the first matching groove 33 and the second matching groove 34 to keep the matching protrusion 731 in the first matching groove 33.

[0068] The limiting member 23 is suitable for limiting the position of the mating protrusion 731. When the central lock is switched to the open state, the limiting member 23 separates the first mating groove 33 from the second mating groove 34, and the limiting member 23 always limits the mating protrusion 731 in the first mating groove 33. Therefore, by providing the limiting member 23, when the central lock is switched to the open state, the mating protrusion 731 can be prevented from moving into the second mating groove 34.

[0069] Optionally, the limiting member 23 is a retaining edge of the central control link 22 .

[0070] According to some embodiments of the present invention, Figure 4-Figure 11 As shown, the transmission mechanism also includes a transmission member 74, which cooperates with the motor 11 and has a convex portion. The transmission arm 71 includes a push arm 72 and a rotating arm 73, which are hinged, and the push arm 72 and the convex portion are detachably cooperated, and the rotating arm 73 is provided with a cooperating protrusion 731.

[0071] The transmission member 74 is along Figure 4 When the central lock is switched to the open state, the motor 11 drives the transmission member 74 to rotate along the first direction, and the convex portion can push the push arm 72 to rotate along the second direction. The push arm 72 is hinged with the rotating arm 73, and the rotating arm 73 is provided with a matching protrusion 731. Figure 4 The first direction of the push arm 72 is rotated, and the push arm 72 is driven to rotate along the second direction. The transmission member 74 drives the push arm 72 along the Figure 4 The locking cam 731 is locked in the locking cam 732 and the locking cam 733 is unlocked. Figure 4 The push arm 72 rotates in the first direction, driving the push arm 72 to rotate along the first direction, and driving the unlocking arm 31 to unlock, thereby realizing the electrolysis function.

[0072] Optionally, the transmission member 74 is a turbine, and the transmission member 74 has a self-resetting spring 75. The self-resetting spring 75 can reset the transmission member 74 after rotating in the first direction or the second direction without the need for the motor 11 to drive it.

[0073] Optionally, the driving mechanism 10 includes a first shaft 13, a second shaft 14, a third shaft 15 and a fourth shaft 16, the central control crank 21 and the child lock crank 41 are sleeved on the first shaft 13, the transmission member 74 is sleeved on the second shaft 14, the inner opening arm 62 is sleeved on the third shaft 15, and the outer opening arm 61 is sleeved on the fourth shaft 16.

[0074] In this embodiment, by providing a single motor 11, the structure of the door lock 100 can be simplified, the production cost can be reduced, the reliability of the door lock 100 can be improved, and the maintenance of the door lock 100 can be facilitated.
