[0083] Embodiment 1:

[0084] The self-priming door lock actuator is used in conjunction with the door lock, the self-priming pull wire and the unlocking pull wire. The unlocking pull wire and the self-priming pull wire are respectively connected to the locking components on the door lock. The movement of the self-priming door lock actuator drives the unlocking pull wire or the self-priming pull wire to move, thereby driving the locking component on the door lock to move, thereby achieving unlocking or self-priming full locking of the door lock.

[0085] Figure 1 : is a three-dimensional structural schematic diagram of the self-priming door lock actuator of this embodiment, Figure 2 Schematic diagram of the working state of the self-priming door lock actuator of this embodiment. Figure 1-2 As shown, the self-priming door lock actuator of the embodiment of the present invention includes a wire fixing frame 1 and a driving device. The wire fixing frame 1 is connected to the self-priming wire B and the unlocking wire C respectively. The driving device is connected to the wire fixing frame 1, and the wire fixing frame 1 is controlled to drive the wire fixing frame 1 to move between the full lock position and the unlocking position. When the wire fixing frame 1 moves in the first direction DIR1, the self-priming wire B is pulled, and when the wire fixing frame 1 moves in the second direction DIR2, the unlocking wire C is pulled, so that the self-priming wire B or the unlocking wire C drives the corresponding locking component on the door lock to move, so as to realize the self-priming full lock or unlocking of the door lock.

[0086] The driving device includes a motor 2 and a transmission mechanism 3. The transmission mechanism 3 is connected to the wire-drawing fixing frame 1. The motor 2 is controlled to drive the transmission mechanism 3 to move. The transmission mechanism 3 converts the rotational motion of the motor 2 into the linear motion of the wire-drawing fixing frame 1.

[0087] The self-priming pull wire B has a first end and a third end, the unlocking pull wire C has a second end and a fourth end, and the pull wire fixing frame 1 is connected to the first end and the second end respectively, and the first end and the second end are arranged opposite to each other. The second end and the fourth end are used to connect with the door lock. The motor 2 is a reversible motor. When the motor 2 rotates in one direction, the motor 2 drives the pull wire fixing frame 1 to move in the first direction DIR1 through the transmission mechanism and pulls the self-priming pull wire B. When the motor 2 rotates in the other direction, the motor 2 drives the pull wire fixing frame 1 to move in the second direction DIR2 through the transmission mechanism and pulls the unlocking pull wire C.

[0088] The transmission mechanism has a variety of configurations, for example, a gear rack mechanism, or a worm gear mechanism, or a lead screw slider mechanism, or other structures that can convert rotational motion into linear motion. In this embodiment, the transmission device adopts a gear set and a rack. The gear rack mechanism works smoothly and has high reliability, and is suitable for application in the self-priming door lock actuator. The rack is fixedly connected to the cable fixing frame 1, and a slide groove is provided in the housing of the self-priming door lock actuator. The rack is at least partially arranged in the slide groove. Through the meshing of the gear and the rack, the rotation of the motor 2 is converted into the linear motion of the rack and the cable fixing frame 1 along the slide groove. The connecting intermediate component is a gear set, and the linear motion component is a rack.

[0089] Optionally, the wire fixing frame 1 is formed with a first limiting hole 11 and a second limiting hole 12, as well as a first surface 13 and a second surface 14 opposite to each other, and the first limiting hole 11 and the second limiting hole 12 both penetrate the wire fixing frame 1. When the wire fixing frame 1 is used in conjunction with the self-priming wire B and the unlocking wire C, the self-priming wire B is passed through the first limiting hole 11 along the first direction DIR1, and then the first tail cap 71 is fixedly connected to the first end of the self-priming wire B, with the first surface 13 facing the first tail cap 71; the unlocking wire C is passed through the second limiting hole 12 along the second direction DIR2, and then the second tail cap 72 is fixedly connected to the second end of the unlocking wire C. That is, the self-priming wire B and the unlocking wire C should be arranged facing each other. The cross section of the first tail cap 71 should be larger than the first limiting hole 11, so that the self-absorption wire B cannot be separated from the first limiting hole 11, and the cross section of the second tail cap 72 should be larger than the second limiting hole 12, so that the unlocking wire C cannot be separated from the second limiting hole 12. Those skilled in the art can also use other structures of the wire fixing frame 1 to connect the self-absorption wire B and the unlocking wire C to the wire fixing frame 1 in opposite directions.

[0090] Preferably, the self-priming door lock actuator further includes a first position sensor, a second position sensor and a third position sensor for detecting the position of the cable fixing frame 1 and generating corresponding signals. The first position sensor, the second position sensor and the third position sensor can be sensors such as travel switches, capacitive sensors, Hall sensors, etc. suitable for detecting whether an object has reached a specific position.

[0091] The first position sensor detects that the wire fixing frame 1 reaches the zero position and generates a zero position signal; the second position sensor is configured to detect that the wire fixing frame 1 reaches the fully locked position and generates a fully locked position signal; the third position sensor is configured to detect that the wire fixing frame 1 reaches the unlocked position and generates an unlocked position signal. The driving device controls the movement of the wire fixing frame 1 according to the zero position signal, the fully locked position signal and the unlocked position signal.

[0092] Specifically, the driving device responds to the full lock position signal, and the motor 2 is controlled to reverse, so that the wire fixing frame 1 moves to the second direction DIR2 to the zero position POS1 until the first position sensor generates a zero position signal. The driving device responds to the full lock position signal, and the motor 2 is controlled to reverse, so that the wire fixing frame 1 moves to the first direction DIR1 to the zero position POS1 until the first position sensor generates a zero position signal. That is, when the wire fixing frame 1 reaches the full lock position or the unlock position, without receiving other instructions, the motor 2 is controlled to drive the wire fixing frame 1 to reset to the zero position POS1 and wait for the next instruction. The zero position POS1 is between the full lock position and the unlock position. When the wire fixing frame 1 is at the zero position POS1, the self-priming wire B and the unlocking wire C will not change the working state of the locking assembly of the door lock connected thereto. Since conventional door locks all have a self-locking function, that is, no slipping or other phenomena will occur in the fully locked state or unlocked state, and the self-priming fully locked and unlocked actions are performed alternately, the motor 2 is set to drive the wire fixing frame 1 to reset to the zero position POS1 according to the fully locked position signal and the unlocked position signal, so that the self-priming wire B or the unlocking wire C can reduce the tension after completing the corresponding action, thereby extending the service life of the self-priming wire B and the unlocking wire C, and at the same time shortening the travel of the wire fixing frame 1 to pull another wire to perform the next action, so that the self-priming door lock actuator can have a faster response speed. Of course, the reset function can also be not set, and the self-priming door lock actuator can make the wire fixing frame 1 stay in the corresponding position after completing an action and wait for the next action to be performed. When the self-priming door lock actuator stays in the fully locked position after completing the self-priming full lock, the function of closing the door can be realized, and even if the unlocking wire C is pulled by other devices (such as the door handle installed on the outside of the car door), it cannot be unlocked, which is generally suitable for use when people leave the car and need to lock the door.

[0093] Of course, the motor 2 can also be controlled to drive the wire fixing frame 1 to return to the zero position POS1 by obtaining the motor rotation value through the encoder installed on the motor 2. Specifically, when the wire fixing frame 1 is in the zero position POS1, after the motor 2 rotates in one direction to reach the predetermined first rotation value, the wire fixing frame 1 moves in the first direction DIR1 to the fully locked position, that is, the door lock connected to the self-priming door lock actuator is in a fully locked state; after the motor 2 rotates in the other direction to reach the predetermined second rotation value, the wire fixing frame moves in the second direction DIR2 to the unlocking position, that is, the door lock connected to the self-priming door lock actuator is in an unlocked state. Therefore, when the rotation value of the motor 2 obtained by the encoder reaches the predetermined first rotation value or the second rotation value, the motor 2 can be controlled to drive the wire fixing frame 1 to return to the zero position POS1.

[0094] like Figure 2 As shown, the self-priming door lock actuator may also include a limiting device for limiting the position of the self-priming pull wire B and / or the unlocking pull wire C. For example, a first spring 41 and a second spring 42 are respectively connected to the self-priming pull wire B and the unlocking pull wire C. When the pull wire fixing frame 1 is in the zero position POS1, the first spring 41 and the second spring 42 are not subjected to pressure; when the pull wire fixing frame 1 moves from the zero position POS1 to the first direction DIR1, the first spring 41 is compressed, and due to the supporting force of the second spring 42, the second end of the unlocking pull wire C remains near the zero position POS1; when the pull wire fixing frame 1 moves from the zero position POS1 to the second direction DIR2, the second spring 42 is compressed, and due to the supporting force of the first spring 41, the first end of the self-priming pull wire B remains near the zero position POS1. Those skilled in the art may also set other forms of limiting devices to limit the range of motion of the self-priming pull wire B and / or the unlocking pull wire C. When the self-priming pull wire B and / or the unlocking pull wire C are sufficiently hard and thick enough, the self-priming pull wire B and / or the unlocking pull wire C can be supported by their own hardness to keep the self-priming pull wire B and / or the unlocking pull wire C near the zero position POS1 even when they are not pulled by the wire fixing frame 1. At this time, the self-priming door lock actuator may not be provided with the limiting device.

[0095] Preferably, a wire tube fixing frame can also be formed on the shell of the self-priming door lock actuator to fix the ends of the wire tubes disposed outside the self-priming pull wire B and the unlocking pull wire C to the self-priming door lock actuator, and at the same time facilitate the control of the travel of the pull wire.

[0096] The self-priming door lock actuator of this embodiment connects the self-priming pull wire and the unlocking pull wire to the pull wire fixing frame. When the pull wire fixing frame moves in the first direction, the self-priming pull wire is pulled, and when it moves in the second direction, the unlocking pull wire is pulled. The pull wire fixing frame is driven by the driving device to move between the full lock position and the unlocking position, and the self-priming pull wire or the unlocking pull wire is pulled, thereby driving the door lock connected to the self-priming pull wire and the unlocking pull wire to complete the self-priming full lock or unlocking function. Therefore, the technical solution of this embodiment can complete the self-priming and unlocking functions through one actuator, with a small size and simple structure.

[0097] Embodiment 2:

[0098] The self-priming door lock actuator of the first embodiment is suitable for use in various devices that need to control two components alternately, and is particularly suitable for use in the field of automobile door locks. The following description will be given by taking the application of the self-priming door lock actuator in an automobile door lock as an example.

[0099] Figure 3-Figure 5 Schematic diagram of a self-priming door lock assembly according to an embodiment of the present invention. Figure 3-Figure 5 As shown, the self-priming door lock assembly of this embodiment includes a door lock module D, a self-priming pull wire B, and an unlocking pull wire C, such as the self-priming door lock actuator A described in the first embodiment, wherein the door lock module D includes a card plate 5 and a stop claw 6, and the stop claw 6 has a protruding locking block 61, and the card plate 5 has a lock groove 51 for accommodating a lock bolt and a first locking surface 52 corresponding to the locking block 61, and the two ends of the self-priming pull wire B are respectively connected to the pull wire fixing frame 1 and the door lock assembly, and the two ends of the unlocking pull wire C are respectively connected to the pull wire fixing frame 1 and the door lock assembly. The driving device drives the pull wire fixing frame 1 to move, pulls the self-priming pull wire B or the unlocking pull wire C, and causes the card plate 5 and the stop claw 6 to move relative to each other, so that the door lock module D completes full locking or unlocking.

[0100] Figure 6 Schematic diagram of the cross-sectional structure of a card board of this embodiment. Figure 6 As shown, in an optional embodiment, a fixing hole 57 and a wire groove 56 are formed on the card plate 5. The fixing hole 57 is used to connect with the third end of the self-priming wire B, and the wire groove 56 is used to limit the position of the self-priming wire B. Optionally, the third tail cap can be embedded in the fixing hole 57, or the third tail cap can be fixedly connected to the fixing hole 57 by other connection methods, and the third end of the self-priming wire B is connected to the third tail cap. The fixing hole 57 should be as far away from the rotating shaft of the card plate 5 as possible, so that a longer force arm can be obtained when the self-priming wire B pulls the card plate 5 to rotate, reducing the required driving force, thereby reducing the workload of the self-priming door lock actuator A.

[0101] Since the connection point between the self-absorption wire B and the card plate 5 is close to the edge of the card plate 5, the working stroke of the self-absorption wire B is long, and the card plate 5 is often shaped with more edges and corners due to the setting of the locking surface and the configuration of the center of gravity position, rather than a smooth cylinder. In order to avoid the self-absorption wire B and the edges on the card plate 5 from rubbing and breaking, and to make the self-absorption wire B smoother when driving the card plate 5 to rotate, to prevent the phenomenon of being stuck, a wire groove 56 can be machined along the extension direction of the self-absorption wire B in the thickness direction of the card plate 5, and the self-absorption wire B is placed in the wire groove 56. Preferably, the bottom surface of the wire groove 56 can be a circular arc segment concentric with the rotation axis of the card plate 5. When the self-absorption wire B pulls the card plate 5 to rotate, the self-absorption wire B is tangent to the bottom surface of the wire groove 56. Optionally, the processing method of the wire groove 56 can adopt a conventional machining method, such as processing using a milling machine.

[0102] Figure 7-Figure 8 Schematic diagram of another structure of the card board of this embodiment. Figure 7-Figure 8 As shown, in another optional embodiment, the card plate 5 includes a main body portion 54 and a wing plate portion 55. A first arc surface 541 is formed in the thickness direction of the main body portion 54, and a first groove 542 is formed on the first arc surface 541. The shape of the first groove 542 can be semicircular, rectangular, trapezoidal or other shapes. A plurality of first grooves 542 can be provided, and a predetermined interval is provided between the plurality of first grooves 542. Those skilled in the art can select the specific shape, number and interval length of the first groove 542 as needed. The main body portion 54 can be made of a material with higher strength, such as carbon steel, etc., to withstand the tensile force and impact force, etc., to which the card plate 5 is subjected during operation.

[0103] The wing plate portion 55 includes a first wing plate and a second wing plate that are arranged opposite to each other, and a connecting portion that connects the first wing plate and the second wing plate. A first protrusion 551 is formed on the connecting portion, and the first protrusion 551 corresponds to the first groove 542 of the main body portion 54. The first wing plate, the second wing plate and the connecting portion can be formed in one piece, for example, the wing plate portion 55 can be formed by injection molding or overmolding, and the material can completely fill the first groove 542 to form the first protrusion 551. The connecting portion can completely cover the first curved surface 541, so that one end surface of the connecting portion and the two wing plates form a wire drawing groove 56, or the first curved surface 541 can be exposed, so that the two wing plates and the first curved surface 541, or the two wing plates, the first curved surface 541 and the end surface of the connecting portion together form the wire drawing groove 56. Since the self-priming pull wire B will generate a large force on the bottom of the pull wire groove 56 when working, this force often exceeds the destructive stress of conventional plastics. Therefore, the first groove 542 and the first protrusion 551 are set to enable the self-priming pull wire B to work on the first curved surface 541 of the main body 54 with high destructive stress, so that the first wing plate and the second wing plate can be connected to each other at least through the first protrusion 551.

[0104] The first end of the self-priming pull wire B is connected to the pull wire fixing frame 1 of the self-priming door lock actuator A, and the second end of the unlocking pull wire C is connected to the pull wire fixing frame 1 of the self-priming door lock actuator A. The connection method is consistent with that in Example 1 and will not be repeated here.

[0105] In this embodiment, the rotation axis of the card plate 5 and the rotation axis of the stop claw 6 are both fixed to the lock housing of the door lock module D, the third end of the self-priming wire B is connected to the card plate 5, and the fourth end of the unlocking wire C is connected to the stop claw 6. When the self-priming door lock actuator A pulls the self-priming wire B, the self-priming wire B drives the card plate 5 to rotate; when the self-priming door lock actuator A pulls the unlocking wire C, the unlocking wire C drives the stop claw 6 to rotate.

[0106] The self-priming door lock assembly of this embodiment also includes a lock bolt sensor for detecting the position of the lock bolt to generate a self-priming signal. The lock bolt sensor can be a capacitive sensor, a Hall sensor, an infrared sensor, a microwave sensor, or other sensor suitable for detecting the approach or contact of an object.

[0107] The bolt sensor of this embodiment is a Hall sensor, which can be arranged in the lock housing, and a magnet can be fixedly arranged in the card plate 5 or the stop claw 6. When the bolt enters the lock slot 51, the card plate 5 and the stop claw 6 will rotate relative to the lock housing, and the magnet installed on the card plate 5 or the stop claw 6 and the Hall sensor on the lock housing will move relative to each other, so that the bolt sensor generates a self-priming signal. In response to the self-priming signal, the driving device drives the wire fixing frame 1 to move in the first direction DIR1, pulling the self-priming wire B.

[0108] Figure 4-Figure 5This is the working principle diagram of the self-priming door lock assembly of this embodiment. Figure 4-Figure 5 The working principle of the self-priming door lock assembly of this embodiment is specifically described.

[0109] The lock bolt sensor of this embodiment is installed on the lock housing, and a magnetic steel 53 is installed at a corresponding position on the card plate 5. Figure 7 The magnetic steel 53 can be embedded near the edge of the card plate 5, or the magnetic steel 53 can be fixed on the card plate 5 through a mounting seat. Figure 4 As shown, when the lock bolt (not shown in the figure) enters the lock slot 51, the card plate 5 rotates, and the magnetic steel and the lock bolt sensor also move relative to each other. The lock bolt sensor detects the entry of the lock bolt and generates a self-priming signal. The self-priming door lock actuator A pulls the self-priming pull wire B in response to the self-priming signal, and the self-priming pull wire B drives the card plate 5 to rotate counterclockwise ( Figure 4 The door lock module D is in a fully locked state and the self-priming full lock is completed. The door lock module D can also be provided with a reset spring, which is connected to the lock housing and the card plate 5. When the door lock module is in an unlocked state, the reset spring is in a pre-tightened state. When the self-priming pull wire B drives the card plate 5 to rotate counterclockwise, the reset spring is tightened, stretched or compressed.

[0110] like Figure 5 As shown, when an unlocking signal is sent to the self-priming door lock actuator A from the outside (for example, the unlocking button is flipped), the self-priming door lock actuator A responds to the unlocking signal, pulls the unlocking cable C, and drives the locking claw 6 to rotate in a clockwise direction ( Figure 5 The locking block 61 is rotated in the clockwise direction in the door lock module D, so that the locking block 61 leaves the first locking surface 52. Due to the elastic force of the reset spring, the card plate 5 rotates in the clockwise direction, so that the lock slot 51 rotates to the opening of the lock shell, and the lock bolt can smoothly exit the door lock module D, and the door lock module D completes unlocking.

[0111] Preferably, the self-priming door lock assembly may also include a fourth position sensor and a fifth position sensor. The fourth position sensor is configured to detect that the lock slot 51 rotates to the first position and generates a first position signal. When the lock slot 51 is in the first position, the first locking surface 52 of the clamping plate 5 and the stop claw 6 are engaged, and the self-priming door lock assembly is in a fully locked state. The drive device drives the pull wire fixing frame to return to the zero position in response to the second position signal. The fifth position sensor is used to detect that the lock slot 51 rotates to the second position and generates a second position signal. When the lock slot 51 is in the second position, the self-priming door lock assembly is in an unlocked state. The drive device drives the pull wire fixing frame to return to the zero position in response to the second position signal. When the self-priming door lock assembly is provided with the fourth position sensor and the fifth position sensor, the second position sensor and the third position sensor may not be provided. The fourth position sensor and the fifth position sensor may be sensors such as travel switches, capacitive sensors, Hall sensors, and reed switches suitable for detecting whether an object has reached a predetermined position. For example, as Figure 7 As shown, a magnetic steel 53 is fixedly installed on the edge of the card plate 5, and Hall sensors are respectively installed on the lock housing of the door lock module D at positions corresponding to the card plate 5 rotating to the second position and the third position. The card plate 5 rotating to the second position is used to indicate that the self-priming door lock assembly is in a fully locked state, and the card plate 5 rotating to the third position is used to indicate that the self-priming door lock assembly is in an unlocked state.

[0112] The driving device can also drive the wire fixing frame 1 to return to the zero position POS1 in response to the second position signal indicating that the clamping plate 5 rotates to the second position or the third position, and wait for the next instruction.

[0113] The self-priming door lock assembly of this embodiment connects the two ends of the self-priming wire and the two ends of the unlocking wire to the wire fixing frame and the door lock module respectively. When the wire fixing frame moves in the first direction, it pulls the self-priming wire, and when it moves in the second direction, it pulls the unlocking wire. The wire fixing frame is driven by the driving device to move between the full lock position and the unlocking position, and the self-priming wire or the unlocking wire is pulled, thereby driving the door lock module connected to the self-priming wire and the unlocking wire to complete the self-priming full lock or unlocking function. Therefore, the technical solution of this embodiment can complete the self-priming and unlocking functions through one actuator, which is small in size and simple in structure.

[0114] Embodiment three:

[0115] Nowadays, a large number of automobile door locks do not have the self-priming function, and it costs a lot to replace ordinary door lock assemblies with self-priming door lock assemblies. This embodiment provides a door lock modification method for modifying an ordinary door lock without the self-priming function into a self-priming door lock, wherein the door lock is a door lock locked by a clamping plate and a stop claw, that is, the door lock includes a clamping plate and a movable claw, the stop claw has a protruding locking block, and the clamping plate has a lock groove for accommodating a lock bolt and a first locking surface corresponding to the locking block.

[0116] The door lock modification method includes the following steps S100 to S400:

[0117] Step S100, connecting the first end of the self-priming pull wire to the self-priming door lock actuator of the first embodiment.

[0118] The self-priming pull wire includes a first end and a third end. The first end is connected to the pull wire fixing frame of the self-priming door lock actuator. The connection method is the same as that in Example 1 and will not be repeated here.

[0119] Step S200, connecting the third end of the self-absorption pull wire to the clamping plate.

[0120] The third end of the self-priming pull wire is fixedly connected to the pallet. The connection point should be as far away from the rotating axis of the pallet as possible so that a longer force arm can be obtained when the self-priming pull wire pulls the pallet to rotate, thereby reducing the required driving force and thus reducing the load on the self-priming door lock actuator.

[0121] The extension direction of the self-priming pull wire should be consistent with the rotation direction of the card plate when it changes from an unlocked state to a fully locked state.

[0122] Preferably, step S200 may include the following steps S210 to S230:

[0123] Step S210, processing a wire groove on the pallet.

[0124] Since the connection point between the self-suction wire and the card plate is close to the edge of the card plate, the working stroke of the self-suction wire is long, and the card plate is often in a shape with more edges and corners, rather than a smooth cylinder, etc., due to the setting of the locking surface and the configuration of the center of gravity. In order to avoid the self-suction wire from breaking due to friction with the edges and corners on the card plate, and to make the self-suction wire smoother when driving the card plate to rotate, to prevent the phenomenon of being stuck, a wire groove 56 can be machined on the card plate along the extension direction of the self-suction wire, and the self-suction wire is placed in the wire groove 56. Preferably, the bottom surface of the wire groove can be a circular arc segment concentric with the rotation axis of the card plate. Optionally, the processing method of the wire groove can adopt a conventional machining method, such as processing using a milling machine.

[0125] In another optional implementation, the step S210 may also include the following steps S211 to S213. Figure 9-12 The door lock modification method of this embodiment adopts the following method from step S211 to step S213 in the process of machining the wire groove on the card board, and the schematic diagram of the card board structure is shown in FIG. Figure 9-12 All of them are cross-sectional structural diagrams of the card plate. In the prior art, most common car door lock original card plates are roughly as follows Fig. 9In the structure shown, the original pallet is mostly made of metal materials such as carbon steel and has great strength.

[0126] Step S211, machining a first curved surface in the thickness direction of the card plate.

[0127] Conventional machining methods can be used to remove part of the material on the original pallet, and a first arc surface 541 can be machined on the original pallet. The first arc surface 541 serves as the bottom of the wire drawing groove. Fig.10 shown.

[0128] Step S212: machining a first groove on the first arc surface.

[0129] like Fig.11 As shown, a conventional machining method can be used to remove part of the material on the first arc surface 541 to form a first groove 542. The shape of the first groove 542 can be semicircular, rectangular, trapezoidal or other shapes. A plurality of first grooves 542 can be provided, and there is a predetermined interval between the plurality of first grooves 542. Those skilled in the art can select the specific shape, number and interval length of the first groove 542 as needed.

[0130] Step S213: forming a wing plate portion 55 on the first curved surface by adding material.

[0131] like Fig.12 As shown, the wing plate portion 55 includes a first wing plate and a second wing plate opposite to each other, and a connecting portion connecting the first wing plate and the second wing plate. Optionally, the wing plate portion 55 can be formed by injection molding. The body portion 54 after step S212 is placed in a mold, and molten plastic, rubber or other materials are injected into the mold by an injection molding machine for overmolding, such as ABS engineering plastics, etc., to form a first wing plate, a second wing plate and a connecting portion in one piece. The injection molding material fills the space in the first groove 542 to form a first protrusion 551 of the connecting portion.

[0132] The connecting part can completely cover the first curved surface 541, so that one end face of the connecting part and the two wing plates form a wire drawing groove, or the first curved surface 541 can be exposed, so that the two wing plates and the first curved surface 541, or the two wing plates, the first curved surface 541 and the end face of the connecting part together form the wire drawing groove. Since the self-priming wire will generate a large force on the bottom of the wire drawing groove when working, and this force often exceeds the breaking stress of conventional plastics, the first groove 542 and the first protrusion 551 are provided, so that the self-priming wire can work on the first curved surface 541 of the main body 54 with high breaking stress, so that the first wing plate and the second wing plate can be connected to each other at least through the first protrusion 551.

[0133] Preferably, at the same time as step S213 , the outside of the main body 54 may be wrapped with injection molding material to form a protective layer to reduce the impact caused by the collision between the clamping plate and the locking claw during operation.

[0134] Since the wire groove is processed by milling and other methods, only a small number of pallets can be processed at the same time on a machine tool, which is inefficient and suitable for small-batch door lock modification. By setting the above steps, processing the first arc surface 541 and the first groove 542 on the pallet is to process the outer contour of one side end surface of the pallet, so a special broach can be designed and processed by broaching. At most, thousands of pallets can be processed on a machine tool at the same time, and the above steps S211 and S212, as well as the semi-finishing and finishing of the first arc surface 541 can be completed in one processing, which is suitable for large-scale door lock modification processes. Alternatively, a stamping device can be used to process the main body 54.

[0135] Step S220, machining fixing holes on the card plate.

[0136] The fixing hole 57 is used to connect with the third end of the self-priming pull wire, and the pull wire groove is used to limit the position of the self-priming pull wire. The fixing hole 57 should be as far away from the rotating shaft of the card plate as possible, so that when the self-priming pull wire pulls the card plate to rotate, a longer force arm can be obtained, reducing the required driving force, thereby reducing the workload of the self-priming door lock actuator.

[0137] Step S230: Connect the third end to the fixing hole.

[0138] Optionally, the third tail cap may be embedded in the fixing hole 57, or the third tail cap may be fixedly connected to the fixing hole 57 by other connection methods, and the third end of the self-absorption pull line is connected to the third tail cap.

[0139] Step S300: Connect the second end of the unlocking wire to the self-priming door lock actuator of the first embodiment.

[0140] The unlocking pull wire includes a second end and a fourth end. The second end is connected to the pull wire fixing frame of the self-priming door lock actuator. The connection method is the same as that in Example 1 and will not be repeated here.

[0141] Step S400: Connect the fourth end of the unlocking wire to the locking claw.

[0142] The fourth end of the unlocking cable is connected to the locking claw, and the connection point and the extending direction of the unlocking cable should be such that when the unlocking cable is pulled by the self-priming door lock actuator, the locking block can be moved away from the card plate.

[0143] Preferably, the method may further include the following step S500:

[0144] Step S500: Install the lock bolt sensor.

[0145] The bolt sensor is used to detect the position of the bolt to generate a self-priming signal, and the self-priming door lock actuator can be configured to drive the wire fixing frame to pull the self-priming wire in response to the self-priming signal indicating that the bolt enters the lock slot 51, thereby achieving a self-priming full lock. The bolt sensor can be a capacitive sensor, a Hall sensor, an infrared sensor, a microwave sensor, or other sensor suitable for detecting an object approaching or contacting.

[0146] Specifically, a Hall sensor can be used as a lock bolt sensor, and the Hall sensor can be fixedly arranged in the lock shell of the door lock, and a magnet is fixedly arranged at a position near the edge of the card plate by punching, embedding, bolting or other means. When the lock bolt enters the lock slot 51, the card plate will rotate relative to the lock shell of the door lock, and the magnet installed on the card plate 5 and the Hall sensor on the lock shell will move relative to each other, so that the lock bolt sensor generates a self-priming signal. In response to the self-priming signal, the drive device drives the wire fixing frame to pull the self-priming wire.

[0147] It should be understood that there is no temporal order relationship between the above steps S100 to S500, that is, the above steps S100 to S500 can be performed in any order. The order of the above steps S210 and S220 can be interchanged.

[0148] It should be understood that the method also includes some related steps, such as opening a hole in the housing of the original door lock to allow the self-priming pull wire to pass through, installing the self-priming door lock actuator in Example 1 on the car, and making related circuit connections. Since these steps are easy for those skilled in the art to think of and are not the focus of the description of the technical solution in this embodiment, they will not be described in detail.

[0149] The door lock modification method of this embodiment utilizes the original door lock module on the car. By connecting the self-priming pull wire to the self-priming door lock actuator and the card plate respectively, and connecting the unlocking pull wire to the self-priming door lock actuator and the locking claw, an ordinary door lock that does not have a self-priming function can be transformed into a self-priming door lock. The operation is simple, the cost is low, and it is suitable for widespread promotion and use.

[0150] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
