When an assembly is considered to be "connected" to another assembly, the assembly may be directly connected to another assembly or there may be an intermediate assembly at the same time.
Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by a person of ordinary skill in the art to which this application belongs. Terms used in the specification of this application are merely intended to describe specific embodiments, but are not intended to limit this application. A term "and/or" as used in this application includes any and all combinations of one or more of associated listed items.
The following describes in detail some implementations of this application with reference to accompanying drawings. In the absence of conflict, the following embodiments and features within the embodiments may be combined with each other.
A door lock apparatus provided in an implementation of this application may be used in a vehicle, which may be specifically a fuel vehicle or a new energy electric vehicle, to help the vehicle achieve functions of opening and locking a door. Specifically, the door lock apparatus includes an inner opening assembly, an outer opening assembly and a central control assembly. The inner opening assembly and the outer opening assembly may be linked. The inner opening assembly may be connected to an inner door handle of the vehicle. A passenger may drive the inner door handle inside a passenger cabin of the vehicle, and such an action may be transmitted to the inner opening assembly, so that a vehicle door is opened or closed. The outer opening assembly may be connected to an outer door handle of the vehicle. A passenger may drive the outer door handle outside the passenger cabin of the vehicle, and such an action may be transmitted to the outer opening assembly, so that the vehicle door is opened or closed. The central control assembly may be configured to drive the door lock apparatus to be switched between a locked state and an unlocked state. In the locked state, the door lock apparatus is locked, and a passenger cannot unlock and open the door through the inner opening assembly and the outer opening assembly inside or outside the passenger cabin. In the unlocked state, the door lock apparatus is unlocked, and a passenger may unlock and open the door by driving the inner opening assembly or the outer opening assembly inside or outside the passenger cabin.
In one implementation, with reference to FIG. 1, a door lock apparatus 100 includes a lock tongue 21, a locking arm 22, a cooperating rocker 23 and a cooperating rocker arm 24. The locking arm 22 rotates around a first rotating shaft 41, and is configured to be engaged with the lock tongue 21. The cooperating rocker 23 and the cooperating rocker arm 24 both rotate around the first rotating shaft 41, the cooperating rocker 23 is connected to the cooperating rocker arm 24, and the cooperating rocker arm 24 rotates and drives the locking arm 22 to rotate around the first rotating shaft 41, so that the locking arm 22 and the lock tongue 21 are converted from an engaged state to a separated state. The outer opening assembly is connected to the cooperating rocker 23, and when the outer opening assembly is unlocked, the outer opening assembly drives the cooperating rocker 23 to rotate to drive the cooperating rocker arm 24 to rotate. The inner opening assembly is connected to the cooperating rocker arm 24, and when the inner opening assembly is unlocked, the inner opening assembly drives the cooperating rocker arm 24 to rotate, and the cooperating rocker 23 does not move.
Specifically, the door lock apparatus 100 may be mounted on a vehicle body or on a vehicle door. The door lock apparatus 100 is configured to cooperate with a lock catch, to close or lock the vehicle door. The door lock apparatus 100 includes a mounting housing 13. The lock tongue 21 and the locking arm 22 are both mounted on the mounting housing 13, and the first rotating shaft 41 passes through the mounting housing 13. The door lock apparatus 100 further includes a shaft of the lock tongue 21. The lock tongue 21 rotates around the shaft of the lock tongue 21. The shaft of the lock tongue 21 also passes through the mounting housing 13, and an axis of the shaft of the lock tongue 21 is parallel to an axis of the first rotating shaft 41. The lock tongue 21 is disposed on the first rotating shaft 41, and can rotate around the first rotating shaft 41 in a clockwise or counterclockwise direction. The locking arm 22 can rotate around the first rotating shaft 41 in a clockwise or counterclockwise direction. The lock tongue 21 includes a locking groove, and the locking groove is configured to accommodate the lock catch. For example, when the vehicle door is gently closed, the lock catch may move into the locking groove. Furthermore, as the vehicle door is gradually closed, the lock catch may be connected to a wall surface of the locking groove to push the lock tongue 21 to gradually rotate, and the locking arm 22 is engaged with the rotated lock tongue 21, so that the lock catch cannot be disengaged from the locking groove, and the door is closed.
In one implementation, each of the lock tongue 21 and the locking arm 22 are connected to a reset spring (not shown in the figure). The lock tongue 21 always keeps rotating counterclockwise under an action of the reset spring, and the locking arm 22 always keeps rotating clockwise under the action of the reset spring. In a locking process, the lock catch drives the lock tongue 21 to rotate in a clockwise direction as the door is closed. When the lock tongue rotates to a fully locked action surface, the locking arm 22 is engaged with the lock tongue 21 in a fully locked position due to potential energy of clockwise rotation. Certainly, in other implementations, the foregoing rotation process may alternatively be reversed. It may be understood that rotation directions of the lock tongue 21 and the locking arm 22 are not limited, and any rotation manner in which the lock tongue is engaged with the locking arm is acceptable.
In one implementation, with reference to FIG. 1 and FIG. 2, the cooperating rocker 23 and the cooperating rocker arm 24 are mounted on a side of the mounting housing 13 facing away from the locking arm 22. Optionally, the cooperating rocker 23 is mounted on a side of the cooperating rocker arm 24 facing away from the mounting housing 13. The cooperating rocker arm 24 may at least partially extend through the mounting housing 13 to a position of the locking arm 22, so that the cooperating rocker arm 24 may also drive the locking arm 22 to rotate correspondingly when the cooperating rocker arm rotates. The cooperating rocker 23 is directly or indirectly connected to the outer opening assembly. When the outer opening assembly moves, the cooperating rocker 23 may be driven to rotate around the first rotating shaft 41. The outer opening assembly may drive the cooperating rocker arm 24 to rotate correspondingly, and finally drive the locking arm 22 to rotate to achieve unlocking. The cooperating rocker arm 24 is directly or indirectly connected to the inner opening assembly. When the inner opening assembly moves, the inner opening assembly may drive the cooperating rocker arm 24 to rotate around the first rotating shaft 41, thereby driving the cooperating rocker arm 24 to rotate correspondingly, and finally driving the locking arm 22 to rotate to achieve unlocking. Furthermore, in a process in which the inner opening assembly moves, the cooperating rocker 23 may be fixed with respect to the first rotating shaft 41, that is, keep stationary, so that the outer opening assembly may not be linked when the inner opening assembly moves. It may be understood that the foregoing cooperating rocker 23 is independent of the cooperating rocker arm 24. That is, when the inner opening assembly drives the cooperating rocker arm 24, the cooperating rocker arm 24 may not drive the cooperating rocker 23 in a reverse direction.
In the door lock apparatus 100 provided in this application, the separate cooperating rocker 23 and cooperating rocker arm 24 are disposed, and the cooperating rocker arm 24 is disposed to connect to the inner opening assembly. When the inner opening assembly drives the cooperating rocker arm 24 to rotate, the cooperating rocker 23 is not affected. In this way, inner opening movement and outer opening movement of the door lock apparatus 100 can be well separated to ensure that an inner opening stroke and an outer opening stroke may not affect each other. In addition, an overall unlocking action may be completed jointly by the cooperating rocker arm 24 and the locking arm 22. Therefore, the door lock apparatus 100 ensures independence of movement strokes and also meets universality of movement parts, and has good functional stability and platform versatility.
In one implementation, with reference to FIG. 1, the door lock apparatus 100 further includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are fit with each other and connected. The upper housing 11 and the lower housing 12 may be provided with a rotating shaft and a reset spring. The outer opening assembly and the inner opening assembly may be both mounted in a space formed after the upper housing 11 and the lower housing 12 are connected, and a corresponding movement function is achieved by the rotating shaft and the reset spring. Each of the upper housing 11 and the lower housing 12 may be further connected to the mounting housing 13.
In one implementation, with reference to FIG. 1, the door lock apparatus 100 further includes a fastening plate 14. The first rotating shaft 41 and the shaft of the lock tongue 21 are fastened to the mounting housing 13 via the fastening plate 14.
In one implementation, with reference to FIG. 2 and FIG. 3, the cooperating rocker 23 is located on a side of the cooperating rocker arm 24 facing away from the locking arm 22. The cooperating rocker 23 includes a rotating portion 231 and a pushing portion 232 connected to each other. The cooperating rocker arm 24 includes a first flange 241. The rotating portion 231 is connected to the first rotating shaft 41. The rotating portion 231 rotates to drive the pushing portion 232 to be connected to the first flange 241, and the pushing portion 232 rotates the cooperating rocker arm 24 by pushing the first flange 241.
Specifically, the rotating portion 231 and the pushing portion 232 are of an integrated structure. The rotating portion 231 is sleeved on an outer periphery of the first rotating shaft 41 to achieve rotatable connection. The pushing portion 232 is connected to an outer periphery of the rotating portion 231, and the outer opening assembly may be connected to an end of the cooperating rocker 23 far away from the pushing portion 232. The first flange 241 is a portion of the cooperating rocker arm 24, which is bent facing away from the mounting housing 13. Therefore, when the cooperating rocker 23 is located on a side of the cooperating rocker arm 24 facing away from the mounting housing 13, the cooperating rocker may be blocked by the first flange 241 in a process in which the pushing portion 232 moves, so that the pushing portion 232 rotates the cooperating rocker arm 24 by pushing the first flange 241.
The pushing portion 232 is disposed to cooperate with the first flange 241, so that when the cooperating rocker 23 is driven to rotate, the cooperating rocker arm 24 may rotate in a same direction when the pushing portion 232 cooperates with the first flange 241.
In one implementation, with reference to FIG. 2 and FIG. 3, the cooperating rocker arm 24 further includes a second flange 242. A minimum distance from the second flange 242 to the first rotating shaft 41 is greater than a maximum distance from the first flange 241 to the first rotating shaft 41. The pushing portion 232 is spaced apart from the second flange 242, and the inner opening assembly is connected to the second flange 242 to rotate the cooperating rocker arm 24 by pushing the second flange 242.
Specifically, the second flange 242 and the first flange 241 may be staggered in a diameter direction of the first rotating shaft 41. That is, a distance from the second flange 242 to the first rotating shaft 41 is greater than a distance from the first flange 241 to the first rotating shaft 41, and a distance from the pushing portion 232 to the first rotating shaft 41 may be equal to a distance from the first flange 241 to the first rotating shaft 41. In this way, when rotating clockwise or counterclockwise, the pushing portion 232 may only be connected to the first flange 241, but cannot be connected to the second flange 242. The minimum distance from the second flange 242 to the first rotating shaft 41 will be understood as a straight-line distance between a point at which the second flange 242 is closest to an outer peripheral wall of the first rotating shaft 41 and the outer peripheral wall; and similarly, the maximum distance from the first flange 241 to the first rotating shaft 41 is a straight-line distance between a point at which the first flange 241 is closest to the outer peripheral wall of the first rotating shaft 41 and the outer peripheral wall.
The second flange 242 may be configured to connect to the inner opening assembly, and the inner opening assembly rotates the cooperating rocker arm 24 by pushing the second flange 242. It may be understood that, it is assumed that when rotating clockwise, the pushing portion 232 may be connected to the first flange 241 and drive the cooperating rocker arm 24 to rotate to achieve unlocking; and the inner opening mechanism may also achieve unlocking by pushing the second flange 242 to rotate clockwise to drive the cooperating rocker arm 24 to rotate, but when being driven, the second flange 242 may not be connected to the pushing portion 232. Therefore, the cooperating rocker 23 may be fixed with respect to the first rotating shaft 41.
The first flange 241 and the second flange 242 are disposed to be staggered, so that when the inner opening assembly drives the cooperating rocker arm 24, the cooperating rocker arm 24 may not drive the cooperating rocker 23, ensuring independence of the outer opening assembly.
In one implementation, with reference to FIG. 2 and FIG. 3, the first flange 241, the second flange 242 and the pushing portion 232 are all located on a same side of the rotating portion 231, and the first flange 241 is spaced apart from the second flange 242 in a circumferential direction of the cooperating rocker arm 24. The pushing portion 232 is located between the first flange 241 and the second flange 242. When the inner opening assembly pushes the second flange 242 to rotate, the second flange 242 is not in contact with the pushing portion 232.
Specifically, because the cooperating rocker 23 and the cooperating rocker arm 24 are stacked, at least a part of the cooperating rocker arm 24 overlaps with a projection of the pushing portion 232 in an axial direction of the first rotating shaft 41. The first flange 241 and the second flange 242 are connected to the part that overlaps with the projection. It may be understood that the first flange 241 is spaced apart from the second flange 242 in the circumferential direction of the cooperating rocker arm 24. The first flange 241 and the second flange 242 are arranged in a non-collinear manner in a radial direction of the first rotating shaft 41. Therefore, the pushing portion 232 may be located between the first flange 241 and the second flange 242. Furthermore, when the first flange 241 and the second flange 242 are at different distances from the first rotating shaft 41, the pushing portion 232 rotates to push the first flange 241, but cannot push the second flange 242.
In the foregoing arrangement manner, the cooperating rocker 23 may be prevented from moving to a position of the second flange 242 and affecting the second flange 242 when moving in the radial direction of the first rotating shaft 41 due to looseness, to ensure stability of the door lock apparatus 100 in a vibrating environment.
In one implementation, with reference to FIG. 2 and FIG. 3, the door lock apparatus 100 further includes a push rod 25 and a locking connecting rod 26 that are in transmission connection. The push rod 25 includes a first position and a second position. The locking connecting rod 26 is configured to drive the push rod 25 to be switched between the first position and the second position. When in the first position, the cooperating rocker arm 24 drives the locking arm 22 through the push rod 25 to rotate. When in the second position, the cooperating rocker arm 24 drives the push rod 25 to rotate, and the locking arm 22 does not rotate.
Specifically, the locking connecting rod 26 may be located on a side of the mounting housing 13 facing away from the lock tongue 21, and the locking connecting rod 26 may rotate around the shaft of the lock tongue 21. The push rod 25 is generally in a shape of a slender rod. One end of the push rod is connected to the locking connecting rod 26, and the other end of the push rod is located on the cooperating rocker arm 24. Furthermore, at least a part of the push rod 25 is located on a side of the push rod 25 facing away from the cooperating rocker arm 24. Optionally, one end of the push rod 25 passes through the cooperating rocker arm 24 and the mounting housing 13 and is located near the locking arm 22. The cooperating rocker arm 24 may drive the push rod 25 to move correspondingly during rotation, so that the push rod 25 may push the locking arm 22 to rotate, thereby achieving unlocking.
In one implementation, with reference to FIG. 4 and FIG. 5, the push rod 25 includes a first cooperating portion 251, and the locking arm 22 includes a second cooperating portion 221. After the cooperating rocker arm 24 rotates to drive the push rod 25 to rotate, the first cooperating portion 251 is connected to the second cooperating portion 221, and the cooperating rocker arm 24 drives the second cooperating portion 221 through the first cooperating portion 251, so that the locking arm 22 rotates to be separated from the lock tongue 21. Specifically, each of the first cooperating portion 251 and the second cooperating portion 221 may have a smooth contact surface. After the push rod 25 rotates until the first cooperating portion 251 is in contact with the second cooperating portion 221, contact surfaces of the first cooperating portion 251 and the second cooperating portion 221 may be connected in a relatively parallel manner. After continuing to rotate, the push rod 25 may thus drive the locking arm 22 to rotate.
In one implementation, with reference to FIG. 2 and FIG. 3, the cooperating rocker arm 24 is provided with an accommodation groove 243. The first cooperating portion 251 is accommodated in the accommodation groove 243. The cooperating rocker arm 24 drives the first cooperating portion 251 through a wall surface of the accommodation groove 243 to move. Specifically, the accommodation groove 243 is formed at an edge of the cooperating rocker arm 24 and extends in a direction of the first rotating shaft 41 to form a "U"-shaped groove 333. The first cooperating portion 251 is accommodated in the accommodation groove 243, and the first cooperating portion 251 extends through the accommodation groove 243 to a plane on which the locking arm 22 is located. After the cooperating rocker arm 24 rotates, the wall surface of the accommodation groove 243 may push the first cooperating portion 251 to drive the push rod 25 to rotate together, and push the locking arm 22 after the first cooperating portion 251 rotates to be in contact with the second cooperating portion 221.
In one implementation, in the first position, the first cooperating portion 251 is located at a position in the accommodation groove 243, which is relatively close to the first rotating shaft 41. The cooperating rocker arm 24 drives the push rod 25 to achieve a movement process in the foregoing implementation. When the push rod 25 is switched from the first position to the second position, the locking connecting rod 26 rotates to drive the push rod 25 to move in an axial direction of the push rod 25, so that the first cooperating portion 251 is located at a position in the accommodation groove 243, which is relatively far away from the first rotating shaft 41. When the cooperating rocker arm 24 drives the push rod 25 to rotate, the first cooperating portion 251 cannot be in contact with the second cooperating portion 221 through rotation, so that the push rod 25 cannot drive the locking arm 22 to rotate for unlocking. It will be understood that because the locking arm 22 and the cooperating rocker arm 24 are coaxial, when a line connecting the farthest distance of the locking arm 22 to the first rotating shaft 41 is shorter than a line connecting the push rod 25 to the first rotating shaft 41, a passenger cannot drive the locking arm 22 by controlling the push rod 25 to rotate.
In one implementation, with reference to FIG. 3 and FIG. 9, the locking connecting rod 26 includes an upper locking connecting rod 26A and a lower locking connecting rod 26B that are in transmission connection. The upper locking connecting rod 26A rotates around a second rotating shaft 42. The lower locking connecting rod 26B rotates around a third rotating shaft 43. The upper locking connecting rod 26A rotates to drive the lower locking connecting rod 26B to rotate. The lower locking connecting rod 26B is connected to the push rod 25. The lower locking connecting rod 26B rotates to drive the push rod 25 to be switched between the first position and the second position. The cooperating rocker arm 24 rotates and drives the push rod 25 to rotate around the lower locking connecting rod 26B.
Specifically, an axis of the second rotating shaft 42 may intersect with an axis of the first rotating shaft 41, and the upper locking connecting rod 26A may be connected to other driving devices. The third rotating shaft 43 may be the shaft of the lock tongue 21 in the foregoing implementation, and the lower locking connecting rod 26B is located on the side of the mounting housing 13 facing away from the lock tongue 21. Further, the lower locking connecting rod 26B may include a first driven end 26B1, and the upper locking connecting rod 26A may include a first driving end 26A1. The first driving end 26A1 may have a groove structure 333. The first driven end 26B1 may be in a shape of a spherical ball and is accommodated in the first driving end 26A1. After the upper locking connecting rod 26A rotates, the first driving end 26A1 drives the first driven end 26B1, to achieve rotation of the lower locking connecting rod 26B. It may be understood that when the upper locking connecting rod 26A rotates in a clockwise direction or a counterclockwise direction, the lower locking connecting rod 26B may also rotate in a counterclockwise direction or a clockwise direction correspondingly.
In one implementation, with reference to FIG. 2 and FIG. 4, the push rod 25 includes a connecting portion 252. The connecting portion 252 is an end of the push rod 25 far away from the first cooperating portion 251. The connecting portion 252 is rotatably connected to the lower locking connecting rod 26B. That is, the push rod 25 may rotate around the connecting portion 252. It may be understood that when the cooperating rocker arm 24 drives the push rod 25 to rotate, the push rod 25 may rotate through the connecting portion 252 correspondingly. Furthermore, in a process in which the lower locking connecting rod 26B rotates, the lower locking connecting rod 26B drives the push rod 25 to move. The push rod 25 may always rotate with respect to the lower locking connecting rod 26B when being restricted by the accommodation groove 243, so as to keep moving in the accommodation groove 243 at the same time. Optionally, the connecting portion 252 is connected to an end of the lower locking connecting rod 26B far away from the first driven end 26B1, so as to obtain a maximum rotation stroke.
In one implementation, with reference to FIG. 3 and FIG. 6, the door lock apparatus 100 further includes a driving member 27, the driving member 27 includes a worm 271, the upper locking connecting rod 26A includes a rack portion 26A2, and the worm 271 is in toothed transmission with the rack portion 26A2. Specifically, the driving member 27 may be a motor, and the worm 271 passes through a rotating shaft of the motor. The rack portion 26A2 is located at an end of the upper locking connecting rod 26A far away from the first driving end 26A1. The rack portion 26A2 is sawtooth-shaped so as to cooperate with the worm 271. The driving member 27 drives the upper locking connecting rod 26A to rotate by driving the worm 271 to rotate forward and backward.
In one implementation, the push rod 25, the locking connecting rod 26, and the driving member 27 mentioned above may all be some parts of the central control assembly. It may be understood that a user may indirectly control the push rod 25 to move between the first position and the second position by controlling start and stop of the driving member 27 through a vehicle-mounted computer in the vehicle. Finally, the door lock apparatus 100 is controlled to be in a locked state or an unlocked state.
In one implementation, with reference to FIG. 6 and FIG. 7, the door lock apparatus 100 further includes a rotating arm 28 and a transmission member 29 that are in transmission connection. The rotating arm 28 is configured to connect to a key. The transmission member 29 is connected to the upper locking connecting rod 26A. The rotating arm 28 rotates to drive the transmission member 29 to move, and the transmission member 29 drives the upper locking connecting rod 26A to rotate.
Specifically, the rotating arm 28 may cooperate with the key. The key is inserted into the rotating arm 28, and then the key is rotated, thereby controlling the rotating arm to rotate. The rotating arm may drive the transmission member 29 to swing correspondingly after rotation. Furthermore, because the transmission member 29 is connected to the upper locking connecting rod 26A, the upper locking connecting rod 26A may be driven to rotate.
In one implementation, with reference to FIG. 6 and FIG. 7, the transmission member 29 rotates around a transmission shaft. The transmission member 29 includes a second driving end 291. The upper locking connecting rod 26A includes a second driven end 26A3. The second driving end 291 may have a groove structure333. The second driven end 26A3 may be in a shape of a cylinder and is accommodated in the second driving end 291. After the transmission member 29 rotates, the second driving end 291 drives the second driven end 26A3, to achieve rotation of the upper locking connecting rod 26A. It may be understood that when the transmission member 29 rotates in a clockwise direction or a counterclockwise direction, the upper locking connecting rod 26A may also rotate in a counterclockwise direction or a clockwise direction correspondingly.
In one implementation, with reference to FIG. 1, the door lock apparatus 100 further includes a mounting plate 31. The lock tongue 21 and the locking arm 22 are mounted on the mounting plate 31. The first rotating shaft 41 is connected to the mounting plate 31. Furthermore, an axis of the first rotating shaft 41 is perpendicular to the mounting plate 31. A direction in which the key is inserted into the rotating arm 28 is perpendicular to the axis of the first rotating shaft 41.
Specifically, the mounting plate 31 and the mounting housing 13 are fit with each other and connected, and enclose an accommodation space. The lock tongue 21 and the locking arm 22 are accommodated in the accommodation space. The first rotating shaft 41 and the third rotating shaft 43 are both fastened to the mounting housing 13 and the mounting plate 31. The mounting plate 31 is generally in a shape of a flat plate. Therefore, the mounting plate 31 can be perpendicular to the axis of the first rotating shaft 41. The rotating arm 28 should have a lock hole that cooperates with a tooth shape of the key. An extension direction of the lock hole is a direction in which the key is inserted into the rotating arm 28. However, because the axis of the first rotating shaft 41 is perpendicular to the mounting plate 31, the direction in which the key is inserted into the rotating arm 28 should be parallel to a surface of the mounting plate 31. Therefore, in arrangement of the door lock apparatus 100, the key may be inserted into the lock hole straightly, which facilitates installation and platform-based design.
In one implementation, with reference to FIG. 1, the door lock apparatus 100 further includes a lock cylinder cover 32. The lock cylinder cover 32 is sleeved on an outer periphery of the rotating arm 28 and connected to the rotating arm 28. The lock cylinder cover 32 may be configured to guide the key to be inserted.
In one implementation, with reference to FIG. 3, the inner opening assembly includes an inner opening rocker arm 33. The inner opening rocker arm 33 rotates around a fourth rotating shaft 44. The inner opening rocker arm 33 rotates to be connected to the cooperating rocker arm 24 and drive the cooperating rocker arm 24 to rotate. Specifically, the inner opening assembly further includes an inner opening rocker 34. The inner opening rocker 34 rotates around a fifth rotating shaft. The inner opening rocker 34 rotates to drive the inner opening rocker arm 33 to rotate. The inner opening rocker 34 may be directly or indirectly connected to the inner door handle. Axes of the fourth rotating shaft 44 and the fifth rotating shaft may be parallel, and axes of the fourth rotating shaft 44 and the first rotating shaft 41 may intersect. The inner opening rocker arm 33 rotates counterclockwise or clockwise to be connected to the cooperating rocker arm 24, and then continues to rotate, so as to push the cooperating rocker arm 24 to rotate correspondingly. A movement relationship after the cooperating rocker arm 24 rotates may refer to the foregoing implementation. Details are not described herein again.
In one implementation, with reference to FIG. 3, the inner opening rocker arm 33 further includes a third flange 331. In a process in which the push rod 25 is switched from the first position to the second position, the inner opening rocker arm 33 rotates to connect the third flange 331 and the upper locking connecting rod 26A. The inner opening rocker arm 33 drives the upper locking connecting rod 26A through the third flange 331 to rotate. The upper locking connecting rod 26A rotates to drive the push rod 25 to be switched from the second position to the first position.
Specifically, the upper locking connecting rod 26A may include a third cooperating portion 26A4. The third cooperating portion 26A4 may be configured to be fitted and connected to the third flange 331. When the driving member 27 indirectly drives the push rod 25 to be located at the second position, the outer opening assembly cannot achieve unlocking by driving the cooperating rocker 23. When a user drives the inner opening rocker arm 33 to rotate for a first time, the inner opening rocker arm 33 cannot achieve unlocking by driving the cooperating rocker arm 24 either. However, during rotation, the cooperating rocker arm 24 may push the third cooperating portion 26A4 through the third flange 331 to drive the upper locking connecting rod 26A. After the upper locking connecting rod 26A rotates, the push rod 25 may be switched from the second position to the first position according to the movement relationship in the foregoing implementation. Thereafter, a user may drive the inner opening rocker arm 33 to rotate again. However, because the push rod 25 has returned to the first position, after the inner opening rocker arm 33 pushes the cooperating rocker arm 24, the push rod 25 may act on the locking arm 22 to achieve unlocking.
In one implementation, with reference to FIG. 8 to FIG. 10, the door lock apparatus 100 provided in this application may be further used for a child lock for a rear door. Specifically, the inner opening assembly may further include an inner opening connecting arm 35, a swing arm 36, and a switching member 37. The inner opening rocker arm 33, the inner opening connecting arm 35, and the swing arm 36 are mounted on the fourth rotating shaft 44, and are all capable of rotating around a rotating shaft. The inner opening connecting arm 35 includes a third position and a fourth position in a radial direction of the fourth rotating shaft 44. In the third position, the inner opening connecting arm 35 drives the swing arm 36 to rotate around the fourth rotating shaft 44, and the swing arm 36 can rotate to be in contact with the cooperating rocker arm 24 and drive the cooperating rocker arm 24 to rotate; and in the fourth position, the swing arm 36 and the inner opening connecting arm 35 are fixed with respect to the fourth rotating shaft 44.
Specifically, with reference to FIG. 8, the inner opening rocker arm 33, the swing arm 36 and the inner opening connecting arm 35 are disposed in a stacked manner. The inner opening rocker arm 33 may be further connected to the inner opening rocker 34 and driven by the inner opening rocker 34. The inner opening rocker arm 33 includes a third driving end 332 and a groove 333. The groove 333 is located between the third driving end 332 and a point at which the inner opening rocker arm 33 is connected to the fourth rotating shaft 44. The groove 333 extends in a circumferential direction around the fourth rotating shaft 44 and has an opening. The swing arm 36 is provided with an accommodation hole 361, and the accommodation hole 361 may extend in a direction of the fourth rotating shaft 44. The inner opening connecting arm 35 includes a third driven end 351. The third driven end 351 may be in a shape of a cylinder, and the third driven end 351 may pass through the accommodation hole 361. When the inner opening connecting arm 35 moves in the radial direction of the fourth rotating shaft 44, the third driven end 351 may also move correspondingly in the accommodation hole 361.
With reference to FIG. 10, when the inner opening connecting arm 35 is located at the third position, the third driven end 351 may be located at an end of the accommodation hole 361 far away from the fourth rotating shaft 44. When the inner opening rocker arm 33 rotates, the third driving end 332 may be connected to the third driven end 351, so that the inner opening connecting arm 35 is driven through the third driven end 351 to rotate. Furthermore, because the third driven end 351 is restricted by the accommodation hole 361, the inner opening connecting arm 35 may drive the swing arm 36 to rotate correspondingly. The swing arm 36 can rotate to be in contact with the cooperating rocker arm 24 and drive the cooperating rocker arm 24 to rotate, to achieve unlocking.
With reference to FIG. 10, when the inner opening connecting arm 35 is located at the fourth position, the third driven end 351 may be located at an end of the accommodation hole 361 close to the fourth rotating shaft 44. When the inner opening rocker arm 33 rotates, the third driven end 351 is accommodated in the groove 333 through the opening. Therefore, the swing arm 36 may not be driven. The swing arm 36 and the inner opening connecting arm 35 are fixed with respect to the fourth rotating shaft 44.
With reference to FIG. 8 and FIG. 9, the switching member 37 and the inner opening connecting arm 35 may be fitted with each other and connected via an axial hole. The switching member 37 may be configured to control the inner opening connecting arm 35 to be switched between the third position and the fourth position.
A switching member 37 is disposed, and the switching member 37 is used to drive the connecting arm to be switched between the third position and the fourth position, so that the inner opening assembly may be locked and unlocked, which is simple in structure and convenient to operate. Furthermore, the inner opening connecting arm 35, the swing arm 36, and the switching member 37 may be directly added to the door lock apparatus 100 provided in the foregoing implementation without re-molding and designing a position of a part, so that the door lock apparatus 100 provided in this application has a high degree of universality, and may be mounted on a front door of a vehicle as a common door lock apparatus 100 and also mounted on a rear door as a child lock, thereby reducing design costs of the door lock apparatus 100.
A complete movement process of the door lock apparatus 100 is described in detail below.
Locking upon closure in the unlocked state: when the vehicle door is gently closed, the lock catch moves into the locking groove, and as the vehicle door is gradually closed, the lock catch is connected to a wall surface of the locking groove to push the lock tongue 21 to rotate. The locking arm 22 always keeps potential energy of rotation under an action of the reset spring. The locking arm 22 is engaged with the lock tongue 21.
Unlocking the outer opening assembly in the unlocked state: when a passenger pulls an outer door handle of the vehicle, the outer opening assembly drives the cooperating rocker 23 to rotate. At this time, the cooperating rocker 23 drives a coaxial cooperating rocker arm 24 to rotate. The cooperating rocker arm 24 pushes the locking arm 22 through the push rod 25 to rotate. The locking arm 22 rotates against an elastic force of the reset spring, so that the lock tongue 21 rotates under the action of the reset spring, and the lock catch may be disengaged to achieve unlocking.
Unlocking the inner opening assembly in the unlocked state: when a passenger pulls an inner door handle of the vehicle, the inner opening rocker 34 drives the inner opening rocker arm 33 to rotate, the inner opening rocker arm 33 pushes the cooperating rocker arm 24 to rotate, and the cooperating rocker 23 keeps stationary. The cooperating rocker arm 24 pushes the locking arm 22 through the push rod 25 to rotate. The locking arm 22 rotates against the elastic force of the reset spring, so that the lock tongue 21 rotates under the action of the reset spring, and the lock catch may be disengaged to achieve unlocking.
Switching between the locked state and the unlocked state: after the vehicle door is closed, the driving member 27 drives the locking connecting rod 26 to pull the push rod 25 to be switched from the first position to the second position. After the cooperating rocker arm 24 drives the push rod 25 to rotate, the push rod 25 cannot be connected to the locking arm 22 to push the locking arm 22. The locking arm 22 and the lock tongue 21 keep stationary and engaged, thereby achieving locking. When a user switches to the unlocked state, the driving member 27 drives the locking connecting rod 26 to pull the push rod 25 to return from the second position to the first position, and the door lock apparatus 100 may achieve the foregoing process of unlocking the outer opening assembly or unlocking the inner opening assembly. In addition, switching between the locked state and the unlocked state may be further achieved by a key. A key is inserted outside the vehicle, and the key is turned to rotate the rotating arm 28. The rotating arm 28 drives the locking connecting rod 26 to move as above through the transmission member 29. The push rod 25 may be switched between the first position and the second position. Subsequent steps are not described again.
Performing double-pull unlocking on the inner opening assembly: when the door lock apparatus 100 is in the locked state, double-pull unlocking is performed on the inner opening assembly. If a passenger inside the vehicle needs to unlock the door in case of an emergency, the passenger may pull a handle inside the vehicle twice to unlock the door. When being pulled for a first time, the inner opening rocker arm 33 pushes the upper locking connecting rod 26A to rotate, and the upper locking connecting rod 26A drives the lower locking connecting rod 26B to rotate, to drive the push rod 25 back to the first position. When the handle inside the vehicle is pulled again, unlocking is achieved according to the foregoing unlocking process of the inner opening assembly.
Switching the child lock between the locked state and the unlocked state: after the vehicle door is closed, a passenger may switch the inner opening connecting arm 35 to the fourth position by controlling the switching member 37. When the inner opening rocker arm 33 rotates, the inner opening rocker arm 33 cannot drive the inner opening connecting arm 35 and the swing arm 36 to rotate correspondingly. That is, the inner opening connecting arm 35 and the swing arm 36 are stationary with respect to the inner opening rocker arm 33, so that the cooperating rocker arm 24 is not driven, thereby achieving locking. Thereafter, the passenger may switch the inner opening connecting arm 35 to the third position by controlling the switching member 37. The inner opening connecting arm 35 and the swing arm 36 may rotate when being driven by the inner opening rocker arm 33, so that the cooperating rocker arm 24 may also be driven to achieve unlocking.
In addition, this application further provides a vehicle 1000. With reference to FIG. 11, the vehicle includes a vehicle door 101 and the door lock apparatus 100 according to the implementations described above. The door lock apparatus 100 is mounted in the vehicle door 101.
