The first embodiment is as follows:

the self-absorption door lock actuator is matched with a door lock, a self-absorption pull wire and an unlocking pull wire for use, the unlocking pull wire and the self-absorption pull wire are respectively connected with a locking component on the door lock, the unlocking pull wire or the self-absorption pull wire is driven to move through the movement of the self-absorption door lock actuator, so that the locking component on the door lock is driven to move, and the unlocking or the self-absorption full locking of the door lock is realized.

Fig. 1 is a schematic perspective view of a self-priming door lock actuator of the present embodiment, and fig. 2 is a schematic view of an operating state of the self-priming door lock actuator of the present embodiment. As shown in fig. 1-2, the self-priming door lock actuator of the embodiment of the present invention includes a pull line fixing frame 1 and a driving device, the pull line fixing frame 1 is connected to a self-priming pull line B and an unlocking pull line C, respectively, the driving device is connected to the pull line fixing frame 1, and the pull line fixing frame 1 is driven to move between a full-locking position and an unlocking position. When the pull wire fixing frame 1 moves towards the first direction DIR1, the self-suction pull wire B is pulled, and when the pull wire fixing frame 1 moves towards the second direction DIR2, the unlocking pull wire C is pulled, so that the self-suction pull wire B or the unlocking pull wire C drives the corresponding locking component on the door lock to move, and the self-suction full locking or unlocking of the door lock is realized.

The driving device comprises a motor 2 and a transmission mechanism 3, the transmission mechanism 3 is connected with the stay wire fixing frame 1, the motor 2 is controlled to drive the transmission mechanism 3 to move, and the transmission mechanism 3 converts the rotary motion of the motor 2 into the linear motion of the stay wire fixing frame 1.

The self-suction pull wire B is provided with a first end and a third end, the unlocking pull wire C is provided with a second end and a fourth end, the pull wire fixing frame 1 is respectively connected with the first end and the second end, and the first end and the second end are arranged in opposite directions. The second end and the fourth end are used for connecting with a door lock. The motor 2 is a reversible motor, when the motor 2 rotates towards one direction, the motor 2 drives the pull wire fixing frame 1 to move towards the first direction DIR1 through the transmission mechanism and pulls the self-absorption pull wire B, and when the motor 2 rotates towards the other direction, the motor 2 drives the pull wire fixing frame 1 to move towards the second direction DIR2 through the transmission mechanism and pulls the unlocking pull wire C.

The transmission mechanism has various configurations, such as a rack and pinion mechanism, or a worm and gear mechanism, or a lead screw slider mechanism, or other structures capable of converting rotational motion into linear motion. In this embodiment, the transmission device adopts a gear set and a rack, and the gear and rack mechanism is stable in operation, high in reliability and suitable for being applied to the self-priming door lock actuator. The rack is fixedly connected with the stay wire fixing frame 1, a sliding groove is formed in the shell of the self-suction door lock actuator, at least part of the rack is arranged in the sliding groove, and the rotation of the motor 2 is converted into the linear motion of the rack and the stay wire fixing frame 1 along the sliding groove through the meshing of the gear and the rack. The connecting intermediate part is a gear set, and the linear motion part is a rack.

Optionally, the wire fixing frame 1 is formed with a first limiting hole 11 and a second limiting hole 12, and a first surface 13 and a second surface 14 opposite to each other, and both the first limiting hole 11 and the second limiting hole 12 penetrate through the wire fixing frame 1. When the pull wire fixing frame 1 is matched with a self-suction pull wire B and an unlocking pull wire C for use, the self-suction pull wire B penetrates through the first limiting hole 11 along the first direction DIR1, then the first tail cap 71 is fixedly connected with the first tail end of the self-suction pull wire B, and the first surface 13 faces the first tail cap 71; the unlocking pull wire C passes through the second limiting hole 12 along the second direction DIR2, and then the second tail cap 72 is fixedly connected with the second end of the unlocking pull wire C. Namely, the self-suction pull wire B and the unlocking pull wire C are oppositely arranged. The first tail cap 71 should have a larger cross-section than the first stopper hole 11 so that the self-priming pull wire B cannot be disengaged from the first stopper hole 11, and the second tail cap 72 should have a larger cross-section than the second stopper hole 12 so that the unlocking pull wire C cannot be disengaged from the second stopper hole 12. The pull-cord fixing bracket 1 with other structures can be adopted by the technical personnel in the field, so that the self-suction pull-cord B and the unlocking pull-cord C are connected with the pull-cord fixing bracket 1 in opposite directions.

Preferably, the self-priming door lock actuator further comprises a first position sensor, a second position sensor and a third position sensor for detecting the position of the wire fixing frame 1 and generating corresponding signals. The first position sensor, the second position sensor, and the third position sensor may be a stroke switch, a capacitive sensor, a hall sensor, or the like suitable for detecting whether an object reaches a specific position.

The first position sensor detects that the stay wire fixing frame 1 reaches a zero position to generate a zero position signal; the second position sensor is configured to detect that the pull wire fixing frame 1 reaches the full-lock position, and generate a full-lock position signal; the third position sensor is configured to detect that the wire fixing bracket 1 reaches the unlocking position, generating an unlocking position signal. The driving device controls the movement of the stay wire fixing frame 1 according to the zero position signal, the full locking position signal and the unlocking position signal.

Specifically, the drive means is responsive to the full lock position signal, the motor 2 is controlled to reverse rotation, moving the cable fixing bracket 1 in the second direction DIR2 to the zero position POS1 until the first position sensor generates a zero position signal. The drive means is responsive to the full lock position signal and the motor 2 is controlled to reverse direction to move the wire holder 1 in a first direction DIR1 to a zero position POS1 until the first position sensor generates a zero position signal. That is, when the wire fixing frame 1 reaches the full locking position or the unlocking position, the motor 2 is controlled to drive the wire fixing frame 1 to reset to the zero position POS1 to wait for the next instruction under the condition that no other instruction is received. The zero position POS1 is located between the full locking position and the unlocking position, and when the pull wire fixing frame 1 is located at the zero position POS1, the self-suction pull wire B and the unlocking pull wire C can not cause the locking component of the door lock connected with the self-suction pull wire B and the unlocking pull wire C to change the working state. Because the conventional door lock has a self-locking function, namely, the phenomena of slippage and the like can not occur in the full-locking state or the unlocking state, and the actions of self-suction full-locking and unlocking are performed alternately, the motor 2 is set to drive the stay wire fixing frame 1 to reset to the zero position POS1 according to the full-locking position signal and the unlocking position signal, so that the tension of the self-suction stay wire B or the unlocking stay wire C can be reduced after the corresponding actions are completed, the service lives of the self-suction stay wire B and the unlocking stay wire C can be prolonged, meanwhile, the stroke of pulling the other stay wire by the stay wire fixing frame 1 to execute the next action can be shortened, and the self-suction door lock actuator can have higher reaction speed. Of course, the self-priming door lock actuator may be configured not to have the reset function, and then the cable fixing frame 1 may be stopped at a corresponding position to wait for the next action after completing one action. When the self-priming door lock actuator stops at the full-lock position after self-priming full locking is completed, the door can be closed and locked, and the unlocking pull wire C can not be unlocked even though being pulled by other devices (such as a door opening handle arranged on the outer side of a vehicle door), so that the self-priming door lock actuator is generally suitable for being used when a person leaves a vehicle and needs to lock the door.

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

As shown in fig. 2, the self-priming door lock actuator may further include a limiting device for limiting the position of the self-priming pull wire B and/or the unlocking pull wire C. For example, the first spring 41 and the second spring 42 are respectively connected with the self-suction pull wire B and the unlocking pull wire C, and when the wire fixing frame 1 is at the zero position POS1, the first spring 41 and the second spring 42 are not stressed; when the wire holding frame 1 moves from the zero position POS1 to the first direction DIR1, the first spring 41 is compressed, and the second end of the unlocking wire C is held near the zero position POS1 due to the supporting force of the second spring 42; when the wire holding frame 1 moves from the zero position POS1 to the second direction DIR2, the second spring 42 is compressed, and the first end of the self-priming wire B is held near the zero position POS1 due to the supporting force of the first spring 41. Other forms of stop means may be provided by those skilled in the art 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 have sufficient hardness and are thick enough or hard enough, the self-priming pull wire B and/or the unlocking pull wire C can be kept near the zero position POS1 even when not pulled by the pull wire fixing frame 1 by means of the self-priming pull wire B and/or the unlocking pull wire C through the self-hardness support of the self-priming pull wire B and/or the unlocking pull wire C, and the self-priming door lock actuator can be also not provided with the limiting device.

Preferably, a wire tube fixing frame can be further formed on the shell of the self-priming door lock actuator, so that the tail ends of wire tubes sleeved outside the self-priming pull wire B and the unlocking pull wire C are fixedly connected with the self-priming door lock actuator, and the travel of the pull wires is convenient to control.

The self-priming door lock actuator of the embodiment connects a self-priming pull wire and an unlocking pull wire with a pull wire fixing frame, the pull wire fixing frame pulls the self-priming pull wire when moving towards a first direction, pulls the unlocking pull wire when moving towards a second direction, drives the pull wire fixing frame to move between a full-lock position and an unlocking position through a driving device, pulls the self-priming pull wire or the unlocking pull wire, and accordingly drives a door lock connected with the self-priming pull wire and the unlocking pull wire to complete the self-priming full-lock or unlocking function. Therefore, the technical scheme of the embodiment can complete the functions of self-suction and unlocking through one actuator, and has the advantages of small volume and simple structure.

Example two:

the self-priming door lock actuator of the first embodiment is suitable for being applied to various devices which need to control two components respectively and alternately, and is particularly suitable for being applied to the field of automobile door locks. The self-priming door lock actuator will be described below with reference to its application to an automotive door lock.

Fig. 3-5 are schematic views of a self-priming door lock assembly according to an embodiment of the present invention. As shown in fig. 3 to 5, the self-priming door lock assembly of the present embodiment includes a door lock module D, a self-priming pull wire B, and an unlocking pull wire C, wherein the self-priming door lock actuator a is as described in the first embodiment, the door lock module D includes a locking plate 5 and a locking pawl 6, the locking pawl 6 is provided with a protruding locking block 61, the locking plate 5 is provided with a locking slot 51 for accommodating a lock bolt and a first locking surface 52 corresponding to the locking block 61, 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 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, and pulls the self-suction pull wire B or the unlocking pull wire C to enable the clamping plate 5 and the locking pawl 6 to move relatively, so that the door lock module D can complete full locking or unlocking.

Fig. 6 is a schematic cross-sectional view of a card board of this embodiment. In an alternative embodiment, as shown in fig. 6, the chucking plate 5 is formed with a fixing hole 57 and a pull line groove 56. The fixing hole 57 is used for connecting with the third end of the self-suction pull wire B, and the pull wire groove 56 is used for limiting the position of the self-suction pull wire B. Alternatively, the third tail cap may be inserted into the fixing hole 57, or the third tail cap may be fixedly connected to the fixing hole 57 by using another connection method, and the third end of the self-priming pull wire B is connected to the third tail cap. The fixing hole 57 should be far from the rotation axis of the chuck plate 5 as far as possible, so as to obtain a longer force arm when the chuck plate 5 is pulled to rotate by the self-priming pull wire B, and reduce the required driving force, thereby reducing the workload of the self-priming door lock actuator a.

The connecting point of the self-suction pull wire B and the clamping plate 5 is close to the edge of the clamping plate 5, so that the working stroke of the self-suction pull wire B is long, and the clamping plate 5 is often in a shape with more edges instead of a smooth cylinder and the like due to the fact that a locking surface is arranged and the gravity center position is configured. In order to avoid the fracture caused by friction between the self-absorption stay wire B and the edge angle on the clamping plate 5, and to enable the self-absorption stay wire B to be smoother when the clamping plate 5 is driven to rotate, the phenomenon of blocking is prevented, a stay wire groove 56 can be processed along the extending direction of the self-absorption stay wire B in the thickness direction of the clamping plate 5, and the self-absorption stay wire B is arranged in the stay wire groove 56. Preferably, the bottom surface of the wire drawing groove 56 may be a circular arc segment concentric with the rotation axis of the card board 5. When the self-suction pull wire B pulls the clamping plate 5 to rotate, the self-suction pull wire B is tangent to the bottom surface of the pull wire groove 56. Alternatively, the wire-drawing groove 56 may be machined by a conventional machining method, such as machining by using a milling machine.

Fig. 7-8 are schematic views of another card of the present embodiment. In another alternative embodiment, as shown in figures 7-8, the card 5 comprises a body portion 54 and a wing portion 55. A first arc surface 541 is formed in the thickness direction of the body portion 54, and a first groove 542 is formed on the first arc surface 541. The shape of the first groove 542 may be a semicircle, a rectangle, a trapezoid, or other shapes. A plurality of first grooves 542 may be provided with a predetermined interval between the plurality of first grooves 542. The specific shape, number and spacing length of the first grooves 542 can be selected by one skilled in the art as desired. The body portion 54 may be made of a material with high strength, such as carbon steel, to withstand the tensile and impact forces, etc. to which the card 5 is subjected during operation.

The flap portion 55 includes a first flap and a second flap which are disposed oppositely, and a connecting portion which connects the first flap and the second flap. The connecting portion is formed with a first projection 551, and the first projection 551 corresponds to the first groove 542 of the body portion 54. The first wing plate, the second wing plate and the connecting portion may be integrally formed, for example, the wing plate portion 55 may be formed by injection molding or over-molding, and the first groove 542 may be completely filled with a material to form the first protrusion 551. The connecting portion may completely cover the first arc surface 541, so that one end surface of the connecting portion and the two wing plates form the pull line groove 56, or the first arc surface 541 may be exposed, so that the two wing plates and the first arc surface 541, or the two wing plates, the first arc surface 541 and the end surface of the connecting portion together form the pull line groove 56. Since the self-sucking pull wire B generates a large force on the bottom of the pull wire groove 56 in operation, which force often exceeds the breaking stress of conventional plastics, the provision of the first groove 542 and the first projection 551 enables the self-sucking pull wire B to operate on the first arc 541 of the body portion 54 having 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 projection 551.

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.

In this embodiment, the rotation shaft of the locking plate 5 and the rotation shaft of the locking pawl 6 are both fixed to the lock case of the door lock module D, the third end of the self-priming pull wire B is connected to the locking plate 5, and the fourth end of the unlocking pull wire C is connected to the locking pawl 6. When the self-suction door lock actuator A pulls the self-suction pull wire B, the self-suction pull wire B drives the clamping plate 5 to rotate; when the self-priming door lock actuator A pulls the unlocking pull wire C, the unlocking pull wire C drives the locking pawl 6 to rotate.

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 latch sensor may be a capacitive sensor, a hall sensor, an infrared sensor, a microwave sensor, or the like suitable for detecting the proximity or contact of an object.

The latch sensor of the present embodiment is a hall sensor, which may be disposed in the lock case, and a magnetic steel may be fixedly disposed in the catch plate 5 or the locking pawl 6. When the lock bolt enters the lock slot 51, the clamping plate 5 and the locking pawl 6 rotate relative to the lock shell, and the magnetic steel arranged on the clamping plate 5 or the locking pawl 6 and the Hall sensor on the lock shell perform relative motion to enable the lock bolt sensor to generate a self-priming signal. The driving device responds to the self-priming signal and drives the pull wire fixing frame 1 to move towards the first direction DIR1 so as to pull the self-priming pull wire B.

Fig. 4 to 5 are schematic diagrams illustrating the operation of the self-priming door lock assembly according to the present embodiment, and the operation of the self-priming door lock assembly according to the present embodiment will be described in detail with reference to fig. 4 to 5.

The latch sensor of this embodiment is mounted on the lock housing and a magnetic steel 53 is mounted at a corresponding position on the catch plate 5, as shown in fig. 7. Can be close to edge embedding magnet steel 53 at cardboard 5, also can fix magnet steel 53 on cardboard 5 through the mount pad. As shown in fig. 4, when a lock plunger (not shown) enters the lock slot 51, the card board 5 rotates, the magnetic steel and the lock plunger sensor also move relatively, and the lock plunger sensor detects the entry of the lock plunger and generates a self-priming signal. The self-priming door lock actuator a pulls the self-priming pull wire B in response to a self-priming signal, the self-priming pull wire B drives the clamping plate 5 to rotate in the counterclockwise direction (the counterclockwise direction in fig. 4) until the first locking surface 52 contacts with the locking block 61, and the door lock module D enters a full-locking state to complete self-priming full locking. Door lock module D can also set up reset spring, and reset spring connects lock shell and cardboard 5, and when door lock module was in the state of unblanking, reset spring was in pretension state, when drawing line B from inhaling driven cardboard 5 along anticlockwise rotation, reset spring was twisted tightly, tensile or compression.

As shown in fig. 5, when an unlocking signal is sent to the self-priming door lock actuator a from the outside (for example, the unlocking button is turned), the self-priming door lock actuator a pulls the unlocking wire C in response to the unlocking signal, and rotates the locking pawl 6 in the clockwise direction (clockwise direction in fig. 5), so that the locking block 61 is separated from the first locking surface 52. The clamping plate 5 rotates clockwise due to the elasticity of the reset spring, so that the lock groove 51 rotates to the opening of the lock shell, the lock bolt can smoothly exit the door lock module D, and the door lock module D completes unlocking.

Preferably, the self-priming door lock assembly may further comprise a fourth position sensor and a fifth position sensor. The fourth position sensor is configured to detect that the key slot 51 is rotated to the first position, generating a first position signal. When the locking slot 51 is in the first position, the catch plate 5 engages with the first locking surface 52 of the locking pawl 6, and the self-priming door lock assembly is in a fully locked state. The driving device responds to the second position signal and drives the stay wire fixing frame to return to the zero position. The fifth position sensor is used for detecting that the lock groove 51 rotates to a second position to generate a second position signal, and when the lock groove 51 is located at the second position, the self-priming door lock assembly is in an unlocking state. The driving device responds to the second position signal and drives the stay wire fixing frame to return to the zero position. 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 and fifth position sensors may be a stroke switch, a capacitive sensor, a hall sensor, a reed switch, or the like suitable for detecting whether an object reaches a predetermined position. For example, as shown in fig. 7, a magnetic steel 53 is fixedly installed on the edge of the card plate 5, and hall sensors are respectively installed on the lock case of the door lock module D at positions corresponding to the second position and the third position to which the card plate 5 is rotated. The clamping plate 5 rotates to the second position and is used for representing that the self-priming door lock assembly is in a full-locking state, and the clamping plate 5 rotates to the third position and is used for representing that the self-priming door lock assembly is in an unlocking state.

The drive means may also drive the pull cord holder 1 back to the zero position POS1, awaiting the next command, in response to the second position signal indicating that the catch plate 5 is rotated to the second or third position.

The self-priming door lock assembly of the embodiment is characterized in that two ends of a self-priming pull wire and two ends of an unlocking pull wire are respectively connected with a pull wire fixing frame and a door lock module, the pull wire fixing frame pulls the self-priming pull wire when moving towards a first direction, the unlocking pull wire is pulled when moving towards a second direction, the pull wire fixing frame is driven by a driving device to move between a full-lock position and an unlocking position, the self-priming pull wire or the unlocking pull wire is pulled, and therefore the door lock module connected with the self-priming pull wire and the unlocking pull wire is driven to complete a self-. Therefore, the technical scheme of the embodiment can complete the functions of self-suction and unlocking through one actuator, and has the advantages of small volume and simple structure.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
