[0051] Figure 1 It is a schematic structural diagram of a side door lock according to an embodiment of the present disclosure.

[0052] like Figure 1 As shown, the side door lock of the present disclosure may include components such as a lock body 100 , a bolt component 200 , a pawl assembly 300 , and an electric unlocking assembly 400 .

[0053] The lock body 100 can be formed as the housing part of the side door lock of the present disclosure, for example, it can include structures such as a back plate and a cover body, and accordingly, components such as a lock tongue component 200 and a pawl assembly 300 can be installed on the back plate and / or the cover body. The installation method of these components can be implemented in the prior art, and the present disclosure will not repeat them one by one.

[0054] In some embodiments of the present disclosure, the bolt member 200 is rotatably disposed on the lock body 100, and the rotation axis of the bolt member 200 relative to the lock body 100 is the first axis. When the bolt member 200 rotates, the bolt member 200 can include at least a locked position and an unlocked position.

[0055] Figure 2 It is a schematic structural diagram of a locking tongue component and a pawl assembly according to an embodiment of the present disclosure. Figure 3 It is a schematic structural diagram of a locking tongue component and a pawl assembly from another angle according to an embodiment of the present disclosure.

[0056] like Figure 2 and Figure 3 As shown, in a specific embodiment, the lock tongue component 200 can be located in a locked position, a semi-locked position, and an unlocked position; in other words, when the lock tongue component 200 is driven to rotate, the lock tongue component 200 can move to one of the locked position, the semi-locked position, and the unlocked position.

[0057] by Figure 2In the state shown, the locking tongue component 200 is in the locked position. Figure 2 In the direction shown, when the lock tongue component 200 rotates counterclockwise, it can be in a semi-locked position and an unlocked position in sequence. In the opposite working process, when the lock tongue component 200 is in the unlocked position and rotates clockwise, it can be in a semi-locked position and a locked position in sequence. When the lock tongue component 200 is in the locked position, the side door lock is in a locked state; when the lock tongue component 200 is in the unlocked position, the side door lock is in an unlocked state.

[0058] In the present disclosure, the counterclockwise movement process (i.e., the unlocking process) of the lock tongue component 200 can be achieved by the elastic force of the return spring. The clockwise movement process (i.e., the locking process) of the lock tongue component 200 can be achieved by the pushing force applied to the lock tongue component 200 by the striker, or by the electric locking mechanism pulling the lock tongue component 200, in which case the side door lock has the function of electric locking. The electric locking mechanism can be implemented by using the solution in the prior art, and the present disclosure will not elaborate on this one by one.

[0059] Refer to Figure 2 and Figure 3 In the present disclosure, the pawl assembly 300 is used to cooperate with the lock tongue component 200 and at least keep the lock tongue component 200 in the locked position; specifically, the pawl assembly 300 of the present disclosure can keep the lock tongue component 200 in the locked position and the semi-locked position.

[0060] In a specific embodiment, the pawl assembly 300 includes: a first pawl component 310 , a second pawl component 320 , a sliding pawl component 330 and other components.

[0061] The first pawl component 310 is rotatably disposed on the lock body 100. The rotation axis of the first pawl component 310 relative to the lock body 100 is a second axis, and the second axis can be parallel to or substantially horizontal with the first axis. Figures 1 to 3 In the orientation shown, the first axis and the second axis may both be disposed substantially vertically.

[0062] The second pawl component 320 is rotatably disposed on the lock body 100. The rotation axis of the second pawl component 320 relative to the lock body 100 is a third axis, which is arranged parallel or substantially parallel to the second axis, and the third axis is spaced apart from the second axis.

[0063] Thus, the first pawl member 310 can hold the bolt member 200 at the locked position, and the second pawl member 320 can hold the bolt member 200 at the semi-locked position.

[0064] The second pawl component 320 of the present disclosure can be driven and rotated by the electric unlocking assembly 400 to unlock the side door lock. Figure 2 In the direction shown, when the second pawl component 320 is driven to rotate counterclockwise, it can drive the sliding pawl component 330 to move and drive the first pawl component 310 to move, and realize the unlocking of the side door lock.

[0065] Specifically, the second pawl component 320 includes a second pawl first groove feature 321 and a second pawl second groove feature 322; the rotation axis of the first pawl component 310 is slidably disposed in the second pawl first groove feature 321, thereby, when the second pawl component 320 is driven and rotated, the first pawl component 310 will not affect the rotation of the second pawl component 320.

[0066] The sliding pawl component 330 includes a sliding pawl first axis feature 331, which can be slidably arranged in the second pawl second groove feature 322, and when the second pawl component 320 rotates, it can drive the sliding pawl component 330 to move, that is, generate a sliding action, thereby, the sliding pawl component 330 can leave from between the first pawl component 310 and the limiting component 340, and allow the first pawl component 310 to rotate counterclockwise, the first pawl component 310 can release the lock tongue component 200, and allow the lock tongue component 200 to leave the locked position and move toward the semi-locked position.

[0067] Refer to Figure 3 The sliding pawl component 330 can also drive the first pawl component 310 to rotate. Specifically, when the second pawl component 320 rotates counterclockwise, the sliding pawl first axis feature 331 of the sliding pawl component 330 can move along the tangential direction of the circle with the third axis as the center line. At this time, the sliding pawl component 330 will push the first pawl component 310 to rotate counterclockwise.

[0068] Those skilled in the art should know that the reverse movement of the first pawl component 310, the second pawl component 320 and the sliding pawl component 330 can be achieved by a return spring, which will not be described in detail here.

[0069] Generally speaking, during the unlocking process of the side door lock, the second pawl component 320 will be driven to rotate counterclockwise; and when the second pawl component 320 is allowed to rotate clockwise and reset, the second pawl component 320 can rotate clockwise and reset under the action of the reset force provided by the reset spring.

[0070] Figure 4 It is a schematic diagram of the principle of a side door lock according to an embodiment of the present disclosure. Figure 5 It is a schematic structural diagram of an electric lock assembly according to one embodiment of the present disclosure.

[0071] The electric unlocking assembly 400 is used to cooperate with the pawl assembly 300 so that the pawl assembly 300 can release the lock tongue component 200; in other words, the electric unlocking assembly 400 of the present disclosure can drive the second pawl component 320 of the pawl assembly 300 to rotate counterclockwise and unlock the side door lock.

[0072] Specifically, the electric unlocking assembly 400 of the present disclosure includes a first motor 410 and a worm gear assembly 420 drivingly connected to the first motor 410. Furthermore, the worm gear assembly 420 may include a worm gear component 421 and a safety drive 422, one end of the safety drive 422 is rotatably connected to the worm gear component 421, and the other end (free end) of the safety drive 422 extends to the outside of the worm gear component 421. A worm is provided on the output shaft of the first motor 410, and the worm can cooperate with the worm gear component 421, so that the worm gear component 421 rotates by the rotation of the worm.

[0073] like Figure 5 As shown, the safety driving member 422 includes a first side surface 422A and a second side surface 422B. Figure 5 In the direction shown, the first side surface 422A is formed as the upper surface of the safety driving member 422, and the second side surface 422B is formed as the lower surface of the safety driving member 422. More preferably, the first side surface 422A is formed as a concave arc surface. The second side surface 422B is formed as a convex arc surface, so that the safety driving member 422 is formed as a curved rod-shaped component as a whole.

[0074] A first retaining spring 423 is provided on the worm wheel component 421 of the worm wheel assembly 420. The first retaining spring 423 is used to limit the safety driving member 422 in the initial position, and when the safety driving member 422 leaves the initial position, the first retaining spring 423 is used to reset the safety driving member 422 to the initial position.

[0075] Specifically, the first retaining spring 423 can be a torsion spring, which can be sleeved on the rotating shaft of the worm gear component 421. The two ends of the first retaining spring 423 are arranged roughly in parallel. Moreover, two columnar portions 422C are arranged on the safety drive 422. The two ends of the first retaining spring 423 are used to clamp the columnar portions 422C, so that the first retaining spring 423 can limit the safety drive 422 to the initial position.

[0076] The worm wheel component 421 of the present disclosure rotates around the fourth axis relative to the lock body 100, and the rotation axis of the safety drive 422 relative to the lock body 100 is the fifth axis, and the fourth axis and the fifth axis are arranged in parallel or approximately in parallel. The worm wheel component 421 has a tangent plane passing through the fifth axis, and the tangent plane is tangent to a cylindrical surface with the fourth axis as the center line; the fourth axis is located on one side of the tangent plane, and the other end of the safety drive 422 is located on the other side of the tangent plane. At this time, there is an angle between the safety drive 422 and the tangent plane (there is an angle between the line connecting one end and the other end of the safety drive 422 and the tangent plane), and the angle value of the angle can change with the rotation of the safety drive 422.

[0077] In a preferred embodiment, the diameter of the columnar portion 422C may be the same as the distance between the two ends of the first clip spring 423. In this case, the distance between the two ends of the first clip spring 423 is the minimum value. When the safety drive member 422 rotates, the distance between the two ends of the first clip spring 423 increases as the angle value of the included angle changes. In this case, the two ends of the first clip spring 423 tend to contract inward, thereby causing the safety drive member 422 to have a tendency to return to the initial position.

[0078] Figure 6 It is a schematic structural diagram of an electric lock assembly from another angle according to an embodiment of the present disclosure. Figure 7 It is a structural schematic diagram of a partial structure of a side door lock according to an embodiment of the present disclosure.

[0079] like Figure 6 and Figure 7 As shown, the electric unlocking assembly 400 of the present disclosure can also operate the rod component 430, and the operating rod component 430 cooperates with the worm gear assembly 420 to drive the operating rod component 430 to rotate through the rotation of the worm gear assembly 420; wherein, when the operating rod component 430 rotates, it can push the pawl assembly 300 to move.

[0080] Specifically, if Figure 6 and Figure 7 As shown, the operating lever component 430 includes an operating lever first arm feature 431, an operating lever second arm feature 432, an operating lever third arm feature 433, and an operating lever slot feature 434. The operating lever first arm feature 431, the operating lever second arm feature 432, and the operating lever third arm feature 433 are all formed as arm portions of the operating lever component 430. The operating lever first arm feature 431 can cooperate with the cam structure 421A on the worm wheel component 421, so that when the worm wheel component 421 rotates, it can push the operating lever component 430 to rotate.

[0081] Specifically, Figure 6In the direction shown in FIG. 4 , when the worm wheel component 421 rotates clockwise, it can push the operating rod component 430 to rotate counterclockwise. Figure 5 In the direction shown, when the worm wheel component 421 rotates counterclockwise, it can push the operating lever component 430 to rotate clockwise. As a result, the operating lever second arm feature 432 of the operating lever component 430 can push the second pawl component 320 to rotate. Figure 2 and Figure 3 In the direction shown, the second pawl component 320 will rotate counterclockwise, thereby unlocking the side door lock.

[0082] Of course, the operating rod component 430 of the present disclosure can rotate counterclockwise (in degrees) under the action of the return spring. Figure 5 direction shown).

[0083] The side door lock of the present disclosure may further include a first manual unlocking assembly 500, which is used to cooperate with the pawl assembly 300 so that the pawl assembly 300 releases the bolt member 200; that is, the first manual unlocking assembly 500 of the present disclosure can be configured to drive the second pawl member 320 of the pawl assembly 300 to rotate. Specifically, Figure 5 As shown, the first manual unlocking assembly 500 is an outward opening pull rod assembly, which may include an outward opening pull rod 510 and an outward opening transmission rod 520 and other components. The outward opening pull rod 510 is rotatably arranged on the lock body 100, and one end of the outward opening pull rod 510 can be connected to the outward opening handle of the side door, and when the outward opening handle of the side door is pulled, the outward opening pull rod 510 can produce a clockwise rotation action. The outward opening transmission rod 520 is rotatably arranged on the lock body 100, and one end of the outward opening transmission rod 520 cooperates with the other end of the outward opening pull rod 510, so that when the outward opening pull rod 510 rotates clockwise, it can push the outward opening transmission rod 520 to rotate counterclockwise.

[0084] The safety lever 600 is configured to rotate around a sixth axis and has a first position and a second position; when the safety lever 600 is in the first position, the first manual unlocking assembly 500 is allowed to drive the pawl assembly 300 to move; when the safety lever 600 is in the second position, the first manual unlocking assembly 500 is not allowed to drive the pawl assembly 300 to move.

[0085] Figures 8 to 10 Schematic diagram of the movement of a safety lever driven from a first position to a second position according to an embodiment of the present disclosure. Figures 11 to 13 Schematic diagram of the movement of the safety lever driven from the second position to the first position according to one embodiment of the present disclosure.

[0086] refer to Figures 8 to 13In the present disclosure, the worm gear assembly 420 is configured to be able to drive the safety lever 600 from the first position to the second position, or to drive the safety lever 600 from the second position to the first position.

[0087] Specifically, an arc groove 610 is provided at the lower end of the safety rod 600, and one end of the safety release rod 700 is slidably and rotatably arranged in the arc groove 610 of the safety rod 600, and the other end of the safety release rod 700 is slidably and rotatably arranged in the operating rod groove feature 434 of the operating rod component 430. Therefore, when the safety rod 600 is driven and rotated, it can drive the safety release rod 700 to produce horizontal displacement.

[0088] Among them, when the safety rod 600 is located in the first position, the outward opening transmission rod 520 of the first manual unlocking component 500 can drive the safety unlocking rod 700 (that is, the other end of the safety unlocking rod 700 is located within the motion envelope of the outward opening transmission rod 520), and drive the operating rod component 430 to rotate through the safety unlocking rod 700; on the other hand, when the safety rod 600 is located in the second position, the first manual unlocking component 500 cannot drive the safety unlocking rod 700. At this time, the other end of the safety unlocking rod 700 is located outside the motion envelope of the outward opening transmission rod 520.

[0089] In a preferred embodiment, a limiting column 710 is provided at one end of the safety release rod 700, and a second retaining spring 601 is provided on the safety pull rod 600. The second retaining spring 601 cooperates with the limiting column 710 to limit one end of the safety release rod 700 to the approximate middle position of the arc groove 610 of the safety pull rod 600.

[0090] More preferably, a limiting protrusion 620 is disposed at the lower end of the safety pull rod 600 , and two ends of the second clamping spring 601 are used to clamp the limiting column 710 and the limiting protrusion 620 ; wherein the two ends of the second clamping spring 601 are disposed substantially in parallel.

[0091] In the present disclosure, the second clamp spring 601 may be a torsion spring, which is sleeved on the rotating shaft of the safety pull rod 600. Moreover, the second clamp spring 601 has the same / similar working principle as the first clamp spring 423, which will not be described in detail in the present disclosure.

[0092] The following will be combined Figures 8 to 13 The specific structure of the safety pull rod 600 and its matching relationship with the worm gear assembly 420 are described below.

[0093] like Figures 8 to 13As shown, the safety lever 600 of the present disclosure includes a first matching portion 630 and a second matching portion 640 ; the safety driving member 422 selectively matches with the first matching portion 630 or the second matching portion 640 to push the safety lever 600 to rotate in different rotation directions.

[0094] When the safety lever 600 is located at the first position, the safety driving member 422 can cooperate with the first matching portion 630 to drive the safety lever 600 from the first position to the second position.

[0095] Specifically, the first matching portion 630 includes a first groove formed at a side of the safety lever 600 , and an opening of the first groove faces the worm gear assembly 420 .

[0096] The first groove includes a first upper side wall 631 and a first lower side wall 632; when the safety lever 600 is in the first position, the other end of the safety drive member 422 contacts the first upper side wall 631 (eg Fig. 9 At this time, since the safety lever 600 is in the first position, it cannot continue to rotate counterclockwise further. Therefore, as the worm wheel component 421 rotates further, the safety driving member 422 will slide along the inner side wall of the first groove and cooperate with the first lower side wall 632 (as shown in FIG. Fig.10 as shown).

[0097] The safety lever 600 is formed with a protrusion 650, and the protrusion 650 is used to form the first upper side wall 631 of the first groove. Fig.10 In the state shown, when the other end of the safety driving member 422 is engaged with the first lower side wall 632, the protrusion 650 contacts the first side surface of the safety driving member 422, and the angle of the safety driving member 422 becomes larger and larger, so as to push the safety pull rod 600 to rotate clockwise (such as Figures 8 to 10 in the direction shown), and moves from the first position to the second position.

[0098] Fig.11 The state shown is that the safety lever 600 is located at the second position. Figures 11 to 13 As shown, when the safety lever 600 is located at the second position, the safety driving member 422 can cooperate with the second matching portion 640 to drive the safety lever 600 from the second position to the first position.

[0099] Specifically, the second matching portion 640 includes a second groove formed at a side of the safety lever 600 , and an opening of the second groove faces the worm gear assembly 420 .

[0100] In other words, the second groove of the present disclosure is located above the first groove, and the portion between the first groove and the second groove is the above-mentioned protrusion 650 .

[0101] The second groove includes a second upper side wall 641 and a second lower side wall 642; when the safety lever 600 is in the second position, the other end of the safety driving member 422 contacts the second upper side wall 641 to push the safety lever 600 to rotate counterclockwise and move from the second position to the first position. In other words, when the safety lever 600 is in the second position, the other end of the safety driving member 422 can pass over the first groove and does not cooperate with the first groove, but directly cooperates with the second groove.

[0102] The protrusion 650 is used to form the second lower side wall 642 of the second groove. When the other end of the safety driving member 422 cooperates with the second upper side wall 641 , the protrusion 650 contacts the second side surface 422B of the safety driving member 422 .

[0103] Generally speaking, when the safety lever 600 is in the first position, the upper end of the safety lever 600 is away from the worm gear assembly 420, and the lower end of the safety lever 600 is close to the worm gear assembly 420; when the safety lever 600 is in the second position, the upper end of the safety lever 600 is close to the worm gear assembly 420, and the lower end of the safety lever 600 is away from the worm gear assembly 420. In this way, the safety lever 600 of the present disclosure can be conveniently matched with the safety driving member 422.

[0104] Based on the above structure, when the side door lock of the present disclosure is working, when the first motor 410 rotates in the first direction, the worm gear component 421 of the electric unlocking assembly 400 will rotate counterclockwise (in degrees). Figure 5 The worm wheel component 421 of the electric unlocking assembly 400 rotates clockwise (in the direction shown in FIG. 1 ), and the worm wheel component 421 of the electric unlocking assembly 400 rotates clockwise (in the direction shown in FIG. 1 ), and the worm wheel component 421 of the electric unlocking assembly 400 rotates clockwise (in the direction shown in FIG. 1 ). Figure 5 In this case, the safety driving member 422 will drive the safety lever 600 to switch between the safety state and the release state of the safety lever 600. At the same time, when the safety lever 600 is in the first position, the safety lever 600 is in the release state, and the side door lock can be opened by the outer opening lever 510. In addition, when the safety lever 600 is in the second position, the safety lever 600 is in the safety state, and the side door lock cannot be opened by the outer opening lever 510.

[0105] Based on the above structure, the side door lock in the present disclosure can be unlocked directly by the electric unlocking assembly, and the electric unlocking assembly can also switch the state of the safety lever 600. At the same time, the electric unlocking assembly realizes these two functions when rotating forward and reversely, and accordingly, when the side door lock is electrically unlocked, the state of the safety lever 600 being on or off will not be affected.

[0106] Fig.14It is a schematic structural diagram of a lock cylinder pull rod according to an embodiment of the present disclosure.

[0107] like Figure 4 and Fig.14 As shown, the side door lock of the present invention may also include a lock core pull rod 101, whereby the side door lock can be installed to the side door corresponding to the driver's seat, and accordingly, the side door lock of the present invention can be opened and closed by a key. Specifically, when the lock core 102 rotates, it can drive the lock core pull rod 101 to move, and drive the safety pull rod 600 through the lock core pull rod 101, and make the safety pull rod 600 be located at the first position or the second position. Further, when it is necessary to open the side door lock, the safety pull rod 600 can be driven to the first position, and then the side door lock can be unlocked by the first manual unlocking assembly 500; when it is necessary to close the side door lock, the safety pull rod 600 can be driven to the second position, whereby even if the first manual unlocking assembly 500 is pulled, the side door lock cannot be unlocked.

[0108] Refer to Figure 6 The side door lock of the present invention may also have an electric child safety function. Specifically, the side door lock of the present invention further includes a child safety component 800. When the child safety component 800 is in the safety-on state, the side door lock cannot be unlocked by the second manual unlocking component 900. When the child safety component 800 is in the safety-off state, the side door lock can be unlocked by the second manual unlocking component 900.

[0109] Specifically, the second manual unlocking assembly 900 of the present disclosure may include an inner opening pull rod, which is rotatably disposed on the lock body 100, and the inner opening pull rod has the same rotation axis as the operating rod component 430, and the inner opening pull rod can selectively cooperate with the third arm feature 433 of the operating rod component 430 to selectively drive the operating rod component 430 to rotate.

[0110] Specifically, the child-safety component 800 may include a second motor 810, which is disposed on the lock body, and a worm is disposed on the output shaft of the second motor 810, which can engage with the child-safety worm wheel 820, and the child-safety worm wheel 820 is rotated by the rotation of the worm.

[0111] An arc-shaped hole is provided on the child-safety worm wheel 820, and one end of the child-safety connecting rod 830 is rotatably and rotatably arranged in the arc-shaped hole of the child-safety worm wheel 820, and an elongated hole is provided on the inner opening pull rod, and the other end of the child-safety connecting rod 830 is rotatably and slidably arranged in the elongated hole.

[0112] Therefore, Figure 7In the direction shown, when the child-proof connecting rod 830 is driven and moves to the right (for example, moves to the right end of the long strip groove), the inner opening pull rod can be connected to the operating rod component 430 in a transmission manner. Specifically, when the inner opening pull rod is driven to rotate clockwise, it can drive the operating rod component 430 to rotate clockwise and unlock the side door lock. On the other hand, when the child-proof connecting rod 830 is driven and moves to the left (for example, moves to the left end of the long strip groove), the clockwise rotation of the inner opening pull rod will not drive the operating rod component 430 to rotate clockwise. Therefore, the side door lock cannot be opened by the inner opening pull rod, and the child-proof function is realized.

[0113] In another embodiment, the child safety link 830 of the present disclosure can be manually operated and moved, thereby enabling the child safety function of the present disclosure to be manually turned on or off.

[0114] In a preferred embodiment, the side door lock may further include a first position detection device, which may be a travel switch, and detects the position of the child-safety worm wheel 820 through the travel switch. When the child-safety component is in the on-safety state, the travel switch can be driven and closed, so that the controller can prohibit the unlocking movement of the first motor according to the closed state of the travel switch. That is, the side door lock cannot be unlocked by the electric unlocking component 400 at this time. In other words, the vehicle controller can shield or open the electric unlocking function according to the state of the child-safety component.

[0115] In another preferred embodiment, the side door lock may further include a second position detection device, which may be a travel switch, and detects the position of the safety lever through the travel switch. When the safety lever is in the safety state, the travel switch can be driven and closed, so that the controller can prohibit the unlocking movement of the first motor according to the closed state of the travel switch. That is, the side door lock cannot be unlocked by the electric unlocking assembly 400 at this time. In other words, the vehicle controller can shield or open the electric unlocking function according to the state of the safety lever.

[0116] Generally speaking, when the side door of the present invention is in use, the electric unlocking function and the manual unlocking function can not affect each other. In the power-off state after the whole vehicle collision, it can also be safely unlocked by the inner opening rod, thereby improving the safety performance of the whole vehicle.

[0117] According to another aspect of the present disclosure, a motor vehicle is provided, which includes the above-mentioned side door lock.
