DETAILED DESCRIPTION

[0046] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0047] In the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0048] like Figure 1-10 As shown, an integrated vehicle door lock of the present invention comprises: a plate-shaped lock body 1 having a plurality of mounting grooves, and a plurality of mechanical parts for cooperating with external opening and external locking are installed along the top and bottom surfaces of the lock body, and the plurality of mechanical parts include:

[0049] The ratchet 3 shaft and the pawl 4 shaft are arranged at intervals, and the two ends of the ratchet 3 shaft and the pawl 4 shaft are respectively vertically penetrated through the top surface and the bottom surface of the lock body 1, and the end of the ratchet 3 shaft located on the bottom surface of the lock body 1 is rotatably penetrated with a ratchet 3, and the end of the pawl 4 shaft located on the bottom surface of the lock body 1 is penetrated with a pawl 4, and the ratchet 3 and the pawl 4 are engaged with each other;

[0050] When the ratchet wheel 3 and the pawl 4 are engaged with each other, the door is locked, and when the ratchet wheel 3 and the pawl 4 are not engaged with each other, the door is opened;

[0051] The ratchet wheel 3 has a lock opening that can engage with the door lock, and a ratchet return spring is fixedly arranged between the ratchet wheel 3 and the lock body 1;

[0052] One end of the pawl 4 close to the ratchet 3 forms a first interference portion, and when the first interference portion faces the ratchet 3 and contacts the ratchet 3, it restricts the ratchet 3 from rotating counterclockwise;

[0053] The outer opening rocker arm 27 is plate-shaped, and the middle part of the outer opening rocker arm 27 can be rotatably sleeved on the end of the pawl 4 shaft located on the top surface of the lock body 1. The outer opening rocker arm 27 includes one end extending out of the lock body 1 and connected to the door handle, and a position away from the end extending out of the lock body 1 is penetrated along the plate body to form a U-shaped groove;

[0054] The locking linkage rocker arm is an irregular triangular shape, wherein one corner is extended to form a spherical end, and a through mounting groove is provided at the side corresponding to the corner, and the middle part of the locking linkage rocker arm is rotatably sleeved on the ratchet 3 shaft;

[0055] The locking push rod 26 is in the shape of a rectangular plate, and one end of which is movably mounted in the U-shaped groove of the locking linkage rocker arm, and the bottom surface of the other end is provided with a connecting block adapted to the U-shaped groove of the first outward opening rocker arm 27, and the connecting block is inserted into the U-shaped groove;

[0056] The top surface of the pawl 4 away from the first interference portion is provided with a protrusion, and the connecting block of the locking push rod 26 interferes with the protrusion. When the door handle is pulled, the outward opening rocker arm 27 rotates, driving the locking push rod 26 to push the protrusion of the pawl 4 and then rotate the pawl 4, so that the first interference portion leaves the ratchet wheel 3, thereby opening the door.

[0057] In the above technical solution, the outward opening function is realized by connecting the outer door handle and the outward opening rocker arm 27 of the lock body 1 through a cable:

[0058] When opening from the outside, pulling the outside door handle drives the outside opening rocker arm 27 to rotate, and the outside opening rocker arm 27 pushes the locking push rod 26 embedded thereon to move, and the other side of the locking push rod 26 pushes the pawl 4 to make way. At this time, the ratchet 3 is opened and the door is opened, wherein the ratchet 3 and the pawl 4 are arranged at the same level and cooperate with each other, one end of the pawl 4 forms an inner concave surface and abuts against the rotation track of the ratchet 3, and the purpose of opening the door can be achieved by rotating the pawl 4 to make way, and then rotating the ratchet 3. wherein, the back sides of the rotation tracks of the pawl 4 and the ratchet 3 shafts are respectively provided with return springs, when the pawl 4 or the ratchet 3 is rotated by external force, it will temporarily push the return spring to undergo elastic deformation, and when the external force is reduced, the return spring rebounds to make the pawl 4 or the ratchet 3 return to its position.

[0059] In another technical solution, the method comprises:

[0060] The outer locking rocker arm 21 has one end extending out of the lock body 1 and is controlled to rotate by the lock core, and the other end can be rotatably sleeved on the ratchet 3 shaft located above the locking linkage rocker arm. The locking push rod 26 is located at one end of the locking linkage rocker arm and is sunken to form a groove. The outer locking rocker arm 21 is fitted above the locking push rod 26 and is located in the groove.

[0061] When the outer locking rocker arm 21 rotates to make the locking push rod 26 reach the unlocking position, the raised part of the locking push rod 26 located at one end of the U-shaped groove of the outer opening rocker arm 27 abuts against the corresponding raised part of the pawl 3. When the door handle is pulled, the outer opening rocker arm 27 rotates, driving the locking push rod to push the raised part of the pawl and then rotate the pawl, so that the first interference part leaves the ratchet 3, thereby opening the door.

[0062] The external locking function is achieved by connecting the door lock cylinder and the external locking rocker arm 21 of the lock body 1 through a pull rod:

[0063] The operation lock core drives the outer locking rocker arm 21 to swing back and forth, thereby driving the locking linkage arm 22 to swing back and forth, so that the locking push rod 26 connected to the locking linkage arm 22 slides back and forth to achieve the purpose of locking and unlocking.

[0064] In another technical solution, a shell 6 perpendicular to the top surface of the lock body 1 is also included, and a plurality of connecting parts perpendicular to the shell 6 are arranged on one end surface of the shell 6 facing the top surface of the lock body 1, which are used to connect various components of the electric lock, including:

[0065] A motor 11 is vertically arranged on one side of the housing 6, with its output end facing downward and connected to a vertical worm 14;

[0066] The double gear 12 includes a large gear and a small gear that are coaxial and fit together, and one side of the large gear is meshed and linked with the worm 14; the end of the small gear away from the worm 14 is connected to the inner locking rocker arm 13, and the inner locking rocker arm 13 includes an arc structure with an arc surface facing outward on one side, and a circle of external teeth meshing with the small gear is arranged on the outer side of the arc. The inner locking rocker arm 13 also includes a slot end with a slot on it, which is clamped on the spherical end of the locking linkage rocker arm. The inner locking rocker arm 13 also includes a protruding structure close to the inner opening rocker arm, which abuts against the inner opening rocker arm.

[0067] When the motor 11 is powered on, the worm 14 on the shaft of the motor 11 rotates, and the double gear 12 meshing with the worm 14 rotates. The inner locking rocker arm 13 is provided with a tooth shape that meshes with the double gear 12, thereby driving the inner locking rocker arm 13 to swing back and forth, so that the locking linkage arm 22 connected to the inner locking rocker arm 13 swings back and forth to achieve the function of locking and unlocking.

[0068] In another technical solution, it also includes an inner locking button, which is fixedly arranged in the vehicle door and connected to the inner locking rocker arm 13 through a cable. By turning the inner locking button, the cable is pulled to drive the inner locking rocker arm 13 to rotate and displace its slot end, thereby driving the locking linkage rocker arm to push or pull the locking push rod 26, so that the part of the locking push rod 26 located at the U-shaped end of the outer opening rocker arm 27 slides or moves away to the unlocking position, so as to achieve the unlocking or locking function.

[0069] In the above technical solution, the inner locking function is realized by connecting the inner locking button of the door with the inner locking rocker arm 13 through a hard steel wire cable:

[0070] Toggling the inner locking button of the door drives the inner locking rocker arm 13 to swing back and forth, thereby driving the locking linkage arm 22 to swing back and forth to achieve the locking and unlocking functions.

[0071] In another technical solution, it also includes an inner opening rocker arm 30 rotatably arranged on the housing 6 and parallel to the inner locking rocker arm 13, the inner opening rocker arm 30 includes an arc portion and a vertical portion, one end of the arc portion is integrated with one end of the vertical portion, the outer arc surface of the arc portion faces the inner locking rocker arm 13, and an arc-shaped protrusion is formed along a side of the outer arc surface close to the housing 6, the side of the inner locking rocker arm 13 close to the inner opening rocker arm 30 abuts against the protrusion, and the end of the vertical portion away from the intersection of the arc portion can be rotatably sleeved on the housing 6;

[0072] The inner opening driven arm 31, the middle of which is rotatably coaxially arranged above the inner opening rocker arm 30, has two ends, one end of which is provided with a square strip-shaped through hole along the plate body, and the other end is formed into a bent connection portion downward and abuts against one side of the ratchet 4, and can push the outer opening rocker arm 27 to rotate;

[0073] The child lock lever 32 is in the shape of a hook plate, one end of which is rotatably arranged on the housing 6 and extends out of the housing 6 to be located in the vehicle body, and the other end of which is close to the housing 6 and downwardly forms a second protrusion, which extends into the through hole on the plate body of the inner opening driven arm 31, and the end of the inner opening rocker arm 30 close to the inner opening driven arm 31 abuts against the second protrusion of the child lock lever 32 located in the through hole;

[0074] The second protrusion can be moved in the square-shaped through hole by rotating the control end. When the second protrusion moves to one end of the square-shaped through hole, the interference end of the inner opening rocker arm 30 close to the inner opening driven arm 31 is formed; when the second protrusion moves to the other end of the square-shaped through hole, it does not interfere with the end of the inner opening rocker arm 30 close to the inner opening driven arm 31.

[0075] When the handle is pulled to drive the inner opening rocker arm 30 to rotate, its arc-shaped protrusion abuts against one end of the inner locking rocker arm 13 and pushes the inner locking rocker arm 13 to rotate, and the slot end of the inner locking rocker arm 13 pushes the locking linkage arm 22 to rotate, thereby pushing the locking push rod 26 to slide to the unlocking position. At this time, the inner door handle is released, and the inner opening rocker arm 30 is reset. Then the inner door handle is pulled again to drive the inner opening rocker arm 30 to rotate, so that the inner opening rocker arm 30 abuts against the second protrusion to form a thrust, pushing the through hole end of the inner opening driven arm and causing it to rotate, thereby causing the inner opening driven arm to move away from the through hole end and push the outer opening rocker arm to rotate, thereby causing the ratchet to give way and open the door.

[0076] In the above technical solution, the inner opening double-pull opening function is realized by connecting the inner door handle and the inner opening rocker arm 30 of the lock body 1 through a cable:

[0077] When the door lock is in the locked state, the first pulling of the inner door handle drives the inner opening rocker arm 30 to rotate. The end of the inner opening rocker arm 30 away from the rotation center is provided with an L-shaped flange protrusion structure, which contacts one end of the inner locking rocker arm 13 and pushes the inner locking rocker arm 13 to rotate, thereby driving the locking linkage arm 22 connected to the other end of the inner locking rocker arm 13 to rotate, so that the locking push rod 26 connected to the locking linkage arm 22 slides to the unlocking position. At this time, the inner door handle is released, the inner opening rocker arm 30 is reset, and then the inner door handle is pulled for the second time to drive the inner opening rocker arm 30 to rotate. The other end of the inner opening rocker arm 30 is provided with a convex shape, which is abutted against the convex structure of the arc end of the child lock lever inserted into the oblong hole of the inner opening driven arm 31, driving the inner opening driven arm 31 to rotate. The inner opening driven arm 31 pushes the outer opening rocker arm 27 to rotate through the bending structure on the outer opening rocker arm 27, and the outer opening rocker arm 27 pushes the locking push rod 26 embedded thereon to move. The other side of the locking push rod 26 pushes the pawl 4 to give way. At this time, the ratchet 3 is opened and the door is opened.

[0078] Among them, the child lock function is realized by turning the child lock lever:

[0079] By moving the raised structure on the end of the child lock lever away from the arc, the child lock lever is embedded in the raised structure in the oblong hole of the inner opening driven arm 31, and moves back and forth along the oblong hole to reach the locked and unlocked positions. When it is moved to the locked position, the raised structure on the arc end of the child lock lever 32 does not contact the inner opening rocker arm 30. When the inner door handle is pulled, the inner opening rocker arm 30 cannot push the inner opening arm 31, so that the door cannot be opened, and the inner opening function is blocked.

[0080] In another technical solution, it also includes a second outward-opening rocker arm 27 and an inward-opening linkage arm. The second outward-opening rocker arm 27 is plate-shaped, and its middle part can be rotatably sleeved on one end of the pawl 4 shaft located on the top surface of the lock body 1, and one end thereof extends out of the lock body 1, and a U-shaped slot is formed at a position away from the end extending out of the lock body 1. The inward-opening linkage arm is sheet-shaped, which is rotatably connected around the pawl 4 shaft, and one end thereof close to the pawl 4 shaft upwardly forms a first outer protrusion perpendicular to the sheet body, which abuts against one end of the inward-opening driven arm 31, and one end thereof away from the pawl 4 shaft downwardly forms a second outer protrusion perpendicular to the sheet body, which is located on the track of the clockwise rotation of the pawl 4;

[0081] When the inner door handle is pulled, the inner opening rocker arm 30 rotates, pushing the inner opening driven arm to rotate, and the inner opening driven arm 31 pushes the first outer protrusion of the inner opening linkage arm so that the second outer protrusion of the inner opening linkage arm pushes the pawl 4 to give way, the ratchet 3 opens, and then the door is opened.

[0082] In the above technical solution, the outward-opening rocker arm 27 is replaced by two parts: an outward-opening rocker arm 272 and an inward-opening linkage arm. At this time, when the inner door handle is pulled, the inward-opening rocker arm 30 rotates and drives the inward-opening linkage arm to rotate through the inward-opening driven arm 31. The inward-opening linkage arm pushes the pawl 4 to give way. At this time, the ratchet 3 opens and the door opens.

[0083] In another technical solution, a micro switch is also included, which is used for door light signal output and lock signal output, and includes:

[0084] A top sheet and a bottom sheet, wherein one end of the top sheet and the bottom sheet are elastically connected to form a V-shaped connecting sheet, and any part of one end away from the top sheet and the bottom sheet can be pressed to fit them together, and a micro-press switch is provided on a side of the bottom sheet close to the top sheet;

[0085] The end of the ratchet 3 away from the pawl 4 forms an outer edge, and the rotation trajectory of the outer edge is exactly consistent with the pressing direction of the top sheet. When the pawl 4 gives way and the ratchet 3 opens, the ratchet 3 rotates to press its outer edge toward the top sheet. At this time, the top sheet approaches the bottom sheet to apply pressure to the micro switch, and the micro switch opens, realizing the door light signal output function;

[0086] Among them, one end of the inner locking rocker arm 13 close to the inner opening rocker arm 30 is just set at the pressing track position from the bottom plate to the top plate. When the inner locking rocker arm 13 rotates to the unlocking or locking position, the inner opening rocker arm 30 presses the bottom plate toward the top plate, and then applies pressure to the micro switch on the bottom plate to realize the locking signal function.

[0087] In the above technical solution, when the door lock is in the locked state and the unlocked state, the lock signal switch 9 can give different signals respectively.

[0088] In another technical solution, an emergency lock function is also included:

[0089] When the vehicle's electronic system fails and the power is cut off, you need to lock the door before leaving. At this time, you can insert the key into the square hole on the emergency knob 28 and rotate it to the limit position (angle 33°) to lock the door. The emergency knob 28 can only lock the door and has no unlocking function.

Install it into the corresponding slot on the lock body 1, and insert the other end of the locking torsion spring 15 into the corresponding hole on the locking linkage arm 22, wherein the other end of the locking push rod 26 is inserted into the corresponding slot of the outer opening rocker arm 27; install the outer locking rocker arm 21 into the corresponding slot of the locking linkage arm 22, and install the emergency knob 28 into the corresponding slot on the lock body 1; align the housing 6 and buckle it on the lock body 1, and tighten it with the hexagonal countersunk self-tapping screws 34; lock the lock signal switch 9 and the door light signal switch 10 are respectively installed in the corresponding slots of the conductive plate 9 and are filled with glue and dried, and then installed in the corresponding slots of the housing 6; the worm 14 is mounted on the motor 11, and then the motor 11 is installed in the corresponding slots of the housing 6, and the double gear 12 and the inner locking rocker arm 13 are installed in the corresponding slots of the housing 6 in turn, and the inner opening rocker arm 30, the inner opening driven arm 31, and the child lock lever are installed in the corresponding slots of the housing 6 in turn, and finally the shell cover 7 is aligned and installed on the housing 6, and tightened with the hexagonal pan head self-tapping screws 23.

[0092] Embodiment 2:

[0093] like Figure 2As shown, the outward opening function is realized by connecting the outer door handle assembly and the outward opening rocker arm on the lock body through a cable. When the outer door handle is pulled by external force, the outward opening rocker arm 27 is driven by the cable to rotate around the pawl shaft, and the end of the locking push rod 26 engaged in its U-shaped notch is also driven to rotate (contact surface 1 100), and the lower end of one end of the locking push rod 26 protrudes below the outward opening rocker arm 27 (contact surface 2 101), and abuts against the protrusion extending upward from the pawl 4, so that the locking push rod 26 rotates to push the pawl 4 to rotate around the pawl shaft, giving way to the ratchet 3, so that the ratchet rotates, so that the lock engaged in the ratchet lock opening is separated from the ratchet, and the door can be opened. When the outer door handle assembly is released, the outward opening rocker arm automatically returns to its position under the action of the outward opening return spring.

[0094] Embodiment three:

[0095] like Figure 3 As shown, the external locking and unlocking functions are realized by connecting the door lock core assembly and the external locking rocker arm on the lock body through a pull rod. When the lock core assembly is turned by the key, the locking linkage rocker arm 22 and the external locking rocker arm 21 are sequentially sleeved on the fixed shaft extending vertically upward from the lock body, the pull rod drives the external locking rocker arm 21 to rotate around the fixed shaft, and the external locking rocker arm 21 drives the locking linkage rocker arm 22 to rotate (contact surface three 102). The locking linkage rocker arm 22 is sleeved on the pawl shaft 29 and is located below the external locking rocker arm 21. The locking linkage rocker arm 22 has a slot downwardly facing the other end of the locking push rod 26 (contact surface four 103). After the two ends of the locking push rod 26 are set to a horizontal state, when the locking linkage rocker arm 22 rotates, the locking push rod is pushed to slide back and forth along the plane where it is located. When it is away from the U-shaped notch of the outward-opening rocker arm 27, the contact surface 101 is disengaged, and it does not interfere with the pawl 3. Therefore, the outward-opening rocker arm 27 cannot drive the pawl to rotate, thereby achieving the purpose of locking; when it is close to the U-shaped notch of the outward-opening rocker arm 27, it and the pawl are against each other, so the outward-opening rocker arm can drive the pawl to rotate and give way, and the ratchet rotates to open the door, thereby achieving the purpose of unlocking.

[0096] Embodiment 4:

[0097] like Figure 4As shown, the inner door opening function is realized by connecting the inner door handle assembly with the inner opening rocker arm on the lock body through a cable. When the inner door handle is pulled by external force, the inner opening rocker arm 30 is driven by the cable to rotate around the inner opening rocker arm shaft, and the other end of the inner opening rocker arm 30 is downwardly pressed from the left against the protrusion extending upward from the opening rocker arm (contact surface 5 104), thereby pushing the opening rocker arm to rotate, and the other end of the opening rocker arm is downwardly arc-flange protrusion to push the pawl 3 to rotate around the pawl shaft (contact surface 6 105), giving way to the ratchet 4, so that the ratchet rotates, so that the lock catch engaged in the ratchet lock opening is separated from the ratchet, and the door can be opened. At the same time, the other end of the L-shaped inner opening rocker arm has a flanged protrusion that contacts the inner locking rocker arm 13, pushing the inner locking rocker arm 13 to rotate (contact surface seven 106), causing the slot end to shift and then drive the locking linkage rocker arm 22 to pull the locking push rod 26, so that the end with the slider slides to a position that can just abut against the protrusion of the pawl 3 (contact surface two 101) to achieve the purpose of unlocking. This process is called the inner opening forced opening function. When the door inner handle assembly is released, the inner opening rocker arm 30 and the opening rocker arm automatically return to their positions under the action of the inner opening return spring.

[0098] Embodiment five:

[0099] like Figure 5 As shown, the double-pull function is realized by connecting the inner handle assembly of the vehicle body with the inner opening rocker arm 30 on the lock body. When the door lock is in the locked state, the inner handle is pulled for the first time, and the inner opening rocker arm 30 is pulled by the inner opening cable to rotate around the axis, and the outer opening rocker arm 27 is pushed through the contact surface 5 104, and the outer opening rocker arm 27 drives the locking push rod 26 to rotate around the pawl axis and move to the end face of the pawl. When the inner opening rocker arm 30 moves to contact with the inner locking rocker arm 13 (contact surface 7 106), it drives the inner locking rocker arm 13 to rotate, and the inner locking rocker arm 13 drives the locking linkage rocker arm 22 to rotate, and the locking linkage rocker arm 22 drives the locking push rod 27 to move linearly, so that the lock is locked. The push rod 27 moves to the end face of the pawl, resulting in the inability to make a linear motion to generate the contact surface 2 101. When the inner opening rocker arm 30 drives the inner locking rocker arm 13 to the limit surface 1, the inner locking rocker arm 13 is in the unlocking stop position. At this time, after the inner handle is released, the inner opening rocker arm 30 and the outer opening rocker arm 27 are reset by the outer opening return spring 19, and the outer opening rocker arm 27 drives the locking push rod 26 back to the locking position. At this time, the locking push rod 26 is driven by the locking push rod return spring 35 to the unlocking stop position. When the inner handle is pulled for the second time, the door lock can be opened normally. The double-pull function is realized.

[0100] Embodiment six:

[0101] like Figure 5As shown, the inner opening function plus the inner locking function is realized by connecting the inner handle assembly of the vehicle body with the inner opening rocker arm 30 and the inner locking rocker arm 13 on the lock body. When the door lock is in the locked state, the inner locking button on the inner handle needs to be turned, and the button is connected to the inner locking rocker arm 13 on the lock body through a hard steel wire cable to drive the inner locking rocker arm 13 to rotate back and forth to achieve unlocking and locking. When the door is in unlocked state, when the inner door handle is pulled by external force, the inner opening rocker arm 30 is driven to rotate through the cable, and the inner opening rocker arm 30 pushes the outer opening rocker arm 27 to rotate through the contact 5, and the outer opening rocker arm 27 rotates and drives one end of the locking push rod 26 engaged in its U-shaped notch to rotate (contact surface 100), and the lower end of one end of the locking push rod 26 protrudes below the outer opening rocker arm 27 (contact surface 2 101), and abuts against the first protrusion extending upward from the pawl 3, so that the locking push rod 26 rotates and drives the pawl 3 to rotate around the pawl shaft, giving way to the ratchet 4, so that the ratchet rotates, so that the lock engaged in the ratchet lock opening is separated from the ratchet, so that the door can be opened. When the inner door handle assembly is released, the inner opening rocker arm and the outer opening rocker arm automatically return to their positions under the action of the outer opening return spring.

[0102] Embodiment seven:

[0103] like Figure 6 and Figure 7 As shown, the child safety lock function is to extend a lever from the lock body to the door for manual operation to lock and unlock the interior. The child lock lever 32 is in a semicircular shape, and one end of the child lock lever is provided with a cylindrical first protrusion which is inserted into the oblong hole of the inner opening driven arm 31. When the child safety is in an unlocked state, the first protrusion is at the end of the oblong hole of the inner opening driven arm 31 away from the rotation center of the inner opening driven arm 31. The inner opening rocker arm 30 and the inner opening driven arm 31 are sequentially mounted on the rotating shaft corresponding to the shell 6. One end of the inner opening rocker arm 30 is provided with an arc structure concentric with the rotating shaft. The width of the end of the arc just abuts against the first protrusion of the child lock lever 32 inserted into the oblong hole of the inner opening driven arm 31 (contact surface 8 107). When the inner door handle is pulled by external force, the inner opening rocker arm 30 is driven to rotate by the cable, and the inner opening driven arm 31 is driven to rotate through contact 8 and the child lock lever. The inner opening driven arm 31 drives the outer opening rocker arm 27 to rotate through contact 9, thereby opening the door. On the contrary, the other end of the child lock lever 32 is operated to extend the protruding part outside the lock body, so that the first protrusion moves toward the rotation center along the oblong hole of the inner opening driven arm 31 and away from the arc structure of the inner opening rocker arm 30, and the contact 8 is disengaged. At this time, the door cannot be opened by the inner door handle.

[0104] Embodiment eight:

[0105] like Figure 8 and Fig. 9As shown, when the vehicle's electronic system fails and the power is cut off, it is necessary to lock the door before leaving. At this time, the key can be inserted into the square hole on the emergency knob 28 and rotated to the limit position (angle 33°) in the direction of the arrow marked on the part, and the locking linkage rocker arm 22 is pushed to the locked position through the contact surface + 109. Since the contact surface + 109 can only transmit movement in one direction (that is, the locking linkage rocker arm 22 can only be pushed by the emergency knob 28), the emergency knob 28 can only lock the door and has no unlocking function.

[0106] Embodiment nine:

[0107] like Fig.10 As shown, when the motor 11 is powered on in the forward direction, the worm 14 on the motor shaft rotates, and the double gear 12 meshing with the worm 14 rotates, and the spur gear on the double gear 12 meshes with the corresponding tooth shape of the inner locking rocker arm 13, drives the inner locking rocker arm 13 to rotate, so that the locking linkage rocker arm 22 rotates, and the locking linkage rocker arm 22 drives the locking push rod 26 to move linearly, so that the contact surface 2 101 is separated from the pawl 3, thereby achieving the function of electric unlocking. When the motor 11 is powered on in the reverse direction, the worm 14 on the motor shaft rotates, and the spur gear on the double gear 12 meshing with the worm 14 meshes with the corresponding tooth shape of the inner locking rocker arm 13, drives the inner locking rocker arm 13 to rotate, so that the locking linkage rocker arm 22 rotates, and the locking linkage rocker arm 22 drives the locking push rod 26 to move linearly, so that the locking push rod 26 is combined with the pawl 3, and the contact surface 2 101 is generated, thereby achieving the function of electric locking.

[0108] It should be noted that modifications in appearance, partial deformation and changes that remain essentially unchanged due to the specific motion logic, mechanical principles, spatial environment and functional requirements of the present invention are all considered to be technical equivalence (infringement).

[0109] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
