Description

[Technical field]

[0001] The utility model relates to the technical field of automobile self-priming locks, in particular to an integrated self-priming lock for an automobile electric door. [Background technology]

[0002] The traditional electric door self-priming door lock has a traditional split structure, consisting of three parts: a central control module, an execution lock block, and a self-priming motor module.

[0003] The central control module is a mechanical logic module mainly composed of safety arms, inner opening arms, outer opening arms, electric opening arms, etc. It has built-in motors and sensor signals such as central control, electric opening, and child locks. It inputs electrical signals from safety bars, inner and outer handles, or door switch signals. Through internal mechanical conversion, it correctly outputs opening actions and status signals to achieve functions such as unlocking, locking, child locks, opening front locks, rear locks, and ground locks. The execution lock block is a mechanical execution module, which is composed of a release plate, opening priority, pawl ratchet, self-priming mechanism, etc. The central control module and self-priming motor module input actions, and the execution lock block implements opening, locking, and opening priority actions. The self-priming motor module is a motor drive device, which is composed of a group of motors, gearboxes, and tension devices.

[0004] When the car door is opened or closed, the mechanism executes the action command to realize a series of door lock functions. Therefore, the traditional split mechanism door lock has the advantages of simple module design, clear functions and convenient maintenance.

[0005] However, the traditional split sliding door self-priming door lock has at least the following problems:

[0006] (1) High efficiency and low cost: Due to the three-module structure, the total number of parts and the workload increase, the transmission efficiency is low, and the total cost increases;

[0007] (2) Low space utilization: Due to the discrete design of the modules, advanced designs such as electric opening and electric suction power, opening priority, and secondary opening cannot be integrated, resulting in a waste of space;

[0008] (3) Bottlenecks in structure and function: As the demand for smart door locks continues to increase, the mechanical logic structure of traditional split sliding door locks has become increasingly complex, and the number of parts, precision, space, etc. requirements have become increasingly high, hindering the development of smart door locks.

[0059] In order to make the purpose, technical solution and beneficial technical effect of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described in this specification are only for explaining the utility model, and are not intended to limit the utility model.

[0060] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0061] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0062] In an embodiment of the utility model, an integrated self-priming lock for an electric door of an automobile is provided, which includes an integrated structure of electric suction and electric opening of the self-priming door lock, a central control and secondary opening structure of the self-priming door lock, and an opening priority structure of the self-priming door lock. Among them, the electric door self-priming door lock (commonly known as the rear lock) is mainly used in the sliding door lock of MPV automobiles, and can also be applied to all automobile side door locks. In addition to having the functions of traditional door locks, it also needs to drag the front lock and the ground lock. It should be noted that the modules included in the integrated structure of electric suction and electric opening of the self-priming door lock, the central control and secondary opening structure of the self-priming door lock, and the opening priority structure of the self-priming door lock may overlap with each other, and this does not serve as a limitation on the above structure.

[0063] like Figure 1-Figure 14 As shown, the integrated self-priming lock for an automobile electric door comprises: a hollow shell 10 and a motor drive module 20 , a transmission module 30 , a clutch module 40 , a central control module 50 and a locking module 60 all arranged in the shell 10 .

[0064] Specifically, the housing 10 includes a first cavity 101 and a second cavity 102. The motor drive module 20, the transmission module 30, the clutch module 40, and the central control module 50 are all accommodated in the first cavity 101, and the locking module 60 is accommodated in the second cavity 102. In order to avoid interference with the glass lifter, the modules in the first cavity 101 are assembled inside the door lock, and the housing structure related to the first cavity 101 and the second cavity 102 is arranged in an L shape (the angle is 90°-120°).

[0065] Furthermore, the second cavity 102 includes an upper shell 11, a lower shell 12, and a middle partition plate (not shown in the figure) disposed between the upper shell 11 and the lower shell 12. A plurality of wire pull rubber caps 13 and wet-dry zone passages (not shown in the figure) are also disposed in the shell 10. Each wire pull rubber cap 13 is used to cooperate with the corresponding pull cable for waterproof sealing. The wet-dry zone passage is in close contact with the middle partition plate, so that the wire harness can be connected on the dry zone side through the connector 14.

[0066] Among them, the waterproof related structures of the utility model mainly include a middle partition, a wire rubber cap sleeve 13 and a dry-wet partition. The dry-wet partition can separate the wet-dry area corridor into a dry area and a wet area. Specifically, the waterproofing of each cable at the door lock end adopts a middle plate positioning, upper shell 11, and lower shell 12 sealing design; the wire waterproofing adopts a die-cast waterproof wall and a wire rubber cap sleeve 13 design; the wire harness waterproofing is on the side of the dry-wet partition of the side facade, establishing a wet area to dry area corridor, and the corridor is closely connected with the dry-wet partition, and the wire harness is connected on the dry area side through a connector 14. In summary, the above-mentioned waterproof design can effectively achieve water spray level waterproofing.

[0067] In the embodiment of the present utility model, combined with Figure 4 and Figure 5 As shown, the transmission module 30 includes: a sector-shaped tooth plate 31 rotatably connected to the inner wall of the shell 10, a first electric opening arm 32 and a self-priming arm 33 respectively arranged on both sides of the sector-shaped tooth plate 31, a second electric opening arm 34 rotatably connected to the inner wall of the shell 10, and an opening arm 35 rotatably connected to the inner wall of the shell 10.

[0068] Specifically, the first electric opening arm 32 includes a first arm 321 and a second arm 322 arranged at an angle, and the angle may be an obtuse angle. The connection between the first arm 321 and the second arm 322 is connected to the sector tooth plate 31 through a first rotating shaft 323, so that the first electric opening arm 32 can rotate around the first rotating shaft 323.

[0069] The first arm 321 is provided with a first stopper 324, and a second stopper 311 is provided at a preset position of the sector tooth plate 31. The first rotating shaft 323 is sleeved with a driving torsion spring 325, and the two ends of the driving torsion spring 325 are respectively abutted against the first stopper 324 and the second stopper 311, so that the second arm 322 maintains a state of abutting against the second stopper 311, that is, when the first electric opening arm 32 is in the initial state (also called the intermediate state) and the electric suction state, the first electric opening arm 32 is retracted as much as possible in the area where the sector tooth plate 31 is located, reducing the space occupied by the first electric opening arm 32 and ensuring the compactness of the design.

[0070] Furthermore, one end of the first arm 321 away from the first rotating shaft 323 is recessed inward to form an arc surface. The second electric opening arm 34 includes a third arm 341 and a fourth arm 342 arranged at an angle, and the connection between the third arm 341 and the fourth arm 342 is connected to the inner wall of the housing 10 through the second rotating shaft 343. Here, the third arm 341 and the fourth arm 342 are respectively located on opposite sides of the second rotating shaft 343 and are arranged roughly in a straight line. Figure 7As shown, the end of the third arm 341 away from the second rotating shaft 343 is provided with an electric arm guide wheel 344, and the electric arm guide wheel 344 can rotate around its own rotating shaft. The first arm 321 cooperates with the electric arm guide wheel 344 through its own arc surface, thereby driving the third arm 341 to rotate around the second rotating shaft 343, thereby causing the fourth arm 342 to press the opening arm 35. Figure 5 As shown, the first electric opening arm 32 and the second electric opening arm 34 both perform rotational movements. Therefore, through the rotational coordination of the arc surface of the first arm 321 and the electric arm guide wheel 344 of the third arm 341, the first arm 321 can ensure a press-fit relationship with the third arm 341 during rotation.

[0071] It can be understood that the predetermined position of the opening arm 35 vertically extends to form a limit block 351 , and the fourth arm 342 abuts against the limit block 351 under the drive of the third arm 341 and can drive the opening arm 35 to rotate.

[0072] Combination Figure 4 As shown, the middle part of the self-priming arm 33 is rotatably connected to the sector tooth plate 31 through the self-priming shaft 331. The self-priming arm 33 includes a first self-priming support arm 332 and a second self-priming support arm 333, which are respectively arranged on opposite sides of the self-priming shaft 331. Here, the first self-priming support arm 332 and the second self-priming support arm 333 are arranged roughly in a straight line. The motor driving module 20 is used to drive the sector tooth plate 31 to rotate in a preset direction to drive the self-priming arm 33 to rotate, thereby switching the locking module 60 to a locked state.

[0073] Combination Figure 4 , Figure 5 and Fig.14 As shown, the locking module 60 includes: a card plate 61 and a stop claw 62. The stop claw 62 is rotatably connected to the inner wall of the housing 10. The card plate 61 is rotatably connected to the inner wall of the housing 10, and a locking groove 611 is provided on a side close to the stop claw 62. The locking groove 611 is used to cooperate with a preset fixing component of the vehicle door. When the vehicle door is closed so that the preset fixing component extends into the locking groove 611 and the opening of the locking groove 611 is closed by the stop claw 62, the locking module 60 is in a locked state, and the vehicle door cannot be opened at this time, and the stop claw 62 will limit the rotation of the card plate 61, so that the card plate 61 maintains a state of cooperation with the preset fixing component; when the card plate 61 rotates so that the preset fixing component is separated from the locking groove 611, the locking module 60 is in an unlocked state, and the vehicle door can be opened at this time.

[0074] Furthermore, the predetermined position of the card plate 61 extends outward to form a driving arm 612. The self-priming arm 33 is used to drive the card plate 61 to rotate by toggling the driving arm 612, that is, when the self-priming arm 33 presses the driving arm 612, the locking groove 611 will cooperate with the preset fixing component, thereby locking the door. Specifically, the second self-priming support arm 333 toggles the driving arm 612 to drive the card plate 61 to rotate.

[0075] The locking module 60 further includes a main release arm 63. The middle portion of the main release arm 63 is coaxially rotatably connected to the inner wall of the housing 10 with the stop claw 62 through a release shaft 631, and the side away from the opening arm 35 is fixedly connected to the stop claw 62, so that the stop claw 62 can rotate synchronously with the main release arm 63. The opening arm 35 drives the stop claw 62 to unlock the card plate 61 by moving the main release arm 63. That is, when the opening arm 35 moves the main release arm 63, it drives the stop claw 62 to rotate, so that the stop claw 62 is separated from the limiting effect on the card plate 61. At this time, the rotation of the card plate 61 is no longer affected, so that the door can be opened manually or electrically.

[0076] Furthermore, a side edge of the main release arm 63 close to the opening arm 35 vertically extends to form a first flange 632, and a side edge of the opening arm 35 close to the main release arm 63 vertically extends to form a second flange 352. When the opening arm 35 abuts against the main release arm 63, the second flange 352 abuts against the first flange 632. The outer surfaces of the first flange 632 and the second flange 352 are both arranged in an arc surface. When the opening arm 35 moves the main release arm 63, since the main release arm 63 is in a rotational motion, the arc surfaces of the first flange 632 and the second flange 352 can adapt to the rotational motion, thereby ensuring that the opening arm 35 normally moves the main release arm 63.

[0077] Among them, the edge preset position of the main release arm 63 extends outward to form a fixed arm 633. A reset torsion spring 634 is sleeved on the release shaft 631; one end of the reset torsion spring 634 abuts on the fixed arm 633, and the other end is fixed in the housing 10 (including the method of being fixed in the fixed seat 15 in the housing 10), so that the main release arm 63 drives the stop claw 62 to maintain the state of locking the card plate 61. That is, when the self-priming arm 33 moves the driving arm 612 to lock the card plate 61 and the stop claw 62, at this time, the self-priming arm 33 is reset, and then the elastic force of the reset torsion spring 634 is used to maintain the stop claw 62 in the state of locking the card plate 61. It should be noted that one end of the reset torsion spring 634 shown in the figure is suspended, but in actual assembly, this end abuts on the fixed arm 633, so the description here is based on the actual assembly situation.

[0078] Furthermore, the locking module 60 also includes a secondary release arm 64. The middle part of the secondary release arm 64 is coaxially rotatably connected to the inner wall of the housing 10 with the stop claw 62. In this embodiment, the secondary release arm 64 is disposed between the main release arm 63 and the stop claw 62 through a release shaft 631. A cable (not shown in the figure) is disposed at one end of the secondary release arm 64 through a through hole. The cable is used to drive the stop claw 62 to unlock the card plate 61 when it is pulled. The other end of the cable can be disposed at the manual door opening button of the vehicle door. When the cable is manually pulled, the secondary release arm 64 is driven to rotate. The rotation direction is consistent with the rotation direction of the main release arm 63 driven by the opening arm 35, so that the stop claw 62 is separated from the limiting effect on the card plate 61, thereby avoiding the situation where the vehicle door cannot be opened in an emergency.

[0079] Combination Fig.14 As shown, the locking groove 611 includes a first side wall 6111 and a second side wall 6112. The first side wall 6111 is arranged on a side of the second side wall 6112 away from the driving arm 612, and a first clamping block 6113 is arranged on the top. The stop claw 62 is provided with a second clamping block 621. The second clamping block 621 includes a rib 6211 and an arcuate edge 6212, the rib 6211 and the arcuate edge 6212 are arranged at an acute angle, and the arcuate edge 6212 is located on a side of the stop claw 62 close to the driving arm 612. When the clamping plate 61 is in the locking stroke, the first clamping block 6113 moves along the arcuate edge 6212 to force the stop claw 62 to rotate outward in a direction away from the locking groove 611; when the clamping plate 61 rotates to the maximum locking stroke or exceeds the locking stroke, the first clamping block 6113 passes over the arcuate edge 6212. At this time, the second block 621 of the stop claw 62 extends into the locking groove 611, and under the action of the return torsion spring 634, it rotates in the direction close to the locking groove 611, and the second block 621 maintains a tendency to extend into the locking groove 611, so that the first block 6113 is clamped on the retaining edge 6211, so that the rotation of the card plate 61 is restricted, and the door is maintained in a locked state. When unlocking is required, the opening arm 35 drives the main release arm 63 to rotate or the auxiliary release arm 64 is pulled, driving the stop claw 62 to rotate in the direction away from the locking groove 611, so that the second block 621 is out of the abutment state with the first block 6113, and the rotation of the card plate 61 is no longer restricted.

[0080] To sum up, the realization principle of the electric suction and electric opening integrated structure of the self-priming door lock is:

[0081] like Figure 4 As shown in the figure, it is an electric suction process, the motor drive module 20 drives the sector tooth plate 31 along the first direction (in Figure 4 The self-priming arm 33 is rotated in a counterclockwise direction to drive the self-priming arm 33 to rotate, thereby driving the card plate 61 to rotate, so that the locking claw 62 closes the locking groove 611 and locks the card plate 61; Figure 5As shown, it is an electric opening process, which is used to drive the sector tooth plate 31 along the second direction (in Figure 5 The first electric opening arm 32 is pressed together in the direction close to the second electric opening arm 34, so that the second electric opening arm 34 drives the locking claw 62 by pressing the opening arm 35 to unlock the card plate 61. When the electric suction and electric opening action is completed, the sector tooth plate 31 will be reset to the initial position. Therefore, the utility model drives the sector tooth plate 31 to rotate through the motor drive module 20, and the power meets the two functions of electric opening and electric suction at the same time, meeting the design requirements of high efficiency, noiselessness and compact space.

[0082] Furthermore, if Figure 3 As shown, the motor drive module 20 includes a drive motor 21, a worm 22 coaxially arranged on the output shaft of the drive motor 21, and a planetary reduction box 23 meshing with the worm 22. The arc edge of the sector gear plate 31 is provided with a gear meshing with the planetary reduction box 23. The drive motor 21 is used to drive the planetary reduction box 23 to operate through the worm 22, thereby driving the sector gear plate 31 to rotate in the first direction or the second direction. Therefore, the planetary power is adopted, based on the double inner push layout, and the electric opening and electric suction actions are output according to the forward and reverse rotations, which can greatly save space.

[0083] The inner wall of the housing 10 is provided with an electric open position switch (not shown in the figure) and an initial position switch (not shown in the figure). The sector tooth plate 31 is provided with a sensing member 312. When the sector tooth plate 31 rotates to the preset initial position, the sensing member 312 is sensed by the initial position switch; when the sector tooth plate 31 rotates along the second direction to the preset electric open position, the sensing member 312 is sensed by the electric open position switch. The electric suction action can also be provided with an electric suction position switch.

[0084] In the embodiment of the present utility model, combined with Figure 7-Figure 11 As shown, the clutch module 40 includes: a first safety arm 41 rotatably connected to a preset position on the inner wall of the housing 10, an opening priority arm 43 rotatably connected to a preset position on the inner wall of the housing 10 through a central control shaft 42, an inner opening arm 44 and an outer opening arm 45. Among them, the inner opening arm 44 is connected to the inner handle (also called inner handle, etc.) of the vehicle door through a corresponding cable structure, and the outer opening arm 45 is connected to the outer handle (also called outer handle, etc.) of the vehicle door through a corresponding cable structure. The through holes of the inner opening arm 44 and the outer opening arm 45 in the figure are the parts connected to the respective cable structures.

[0085] The opening arm 35 is rotatably matched with the central control shaft 42, and is rotatably connected to a second safety arm 47 via a safety shaft 46 on a side away from the opening priority arm 43. Both the inner opening arm 44 and the outer opening arm 45 can drive the opening priority arm 43 to rotate in the same direction, thereby driving the opening arm 35 to rotate, thereby unlocking the locking module 60.

[0086] Specifically, combined Figure 12-13 As shown, the second safety arm 47 is provided with a safety torsion spring 471. The safety torsion spring 471 is sleeved on the safety shaft 46, one end of which abuts against the preset position of the opening arm 35, and the other end abuts against the second safety arm 47, so that the second safety arm 47 maintains a state of cooperation with the opening priority arm 43, so that the opening priority arm 43 can drive the opening arm 35 to rotate. Among them, when the second safety arm 47 abuts against the opening priority arm 43, it includes both an abutment component along the vertical direction of the opening priority arm 43 and an abutment component along the parallel direction of the opening priority arm 43. At this time, as shown in FIG. Fig.12 As shown, if the opening priority arm 43 rotates in the direction close to the second safety arm 47, since there is an acute angle between the force application point and the two connecting lines of the stroke of the central control axis 42 and the safety axis 46, the abutment along the parallel direction of the opening priority arm 43 when it rotates and the component of the second safety arm 47 will exert a pressure on the safety axis 46. Since the safety axis 46 is arranged on the opening arm 35, the safety axis 46 will rotate around the central control axis 42, thereby driving the opening arm 35 to rotate, thereby achieving the effect that when the second safety arm 47 abuts against the opening priority arm 43, the opening priority arm 43 can drive the opening arm 35 to rotate. It should be noted that the second electric opening arm 34 drives the opening arm 35 to open the door electrically, and the second safety arm 47 drives the opening arm 35 to be affected by the actions of the inner opening arm 44 (pulling the inner handle to open the door) and the outer opening arm 45 (pulling the outer handle to open the door). The two ways of driving the opening arm 35 are independent of each other, that is, the opening arm 35 can open the door automatically by electric means, and can also open the door manually by pulling the inner handle and the outer handle.

[0087] The central control module 50 is used to drive the first safety arm 41 to rotate, thereby pressing the second safety arm 47, so that one end of the second safety arm 47 is tilted, so that the second safety arm 47 maintains a state of being separated from the opening priority arm 43. When the user issues a command such as locking the car to the central control module 50, the central control module 50 presses the second safety arm 47 through the first safety arm 41, so that the second safety arm 47 is decoupled from the opening priority arm 43. At this time, the rotation of the opening priority arm 43 driven by the inner opening arm 44 or the outer opening arm 45 will not drive the opening arm 35 to rotate, that is, at this time, the door cannot be opened by pulling the inner handle or the outer handle.

[0088] Specifically, the central control module 50 includes: a central control motor 51, a central control worm 52 coaxially arranged with the output shaft of the central control motor 51, and a central control turbine 53 meshing with the central control worm 52. The central control turbine 53 is provided with a first driving rod 54, which is used to drive the first safety arm 41 to rotate in a forward or reverse direction.

[0089] The first safety arm 41 includes a semicircular safety arm body 411 and a drive block 412 extending outwardly from the arc surface of the safety arm body 411. The drive block 412 is used to control the second safety arm 47 to disengage from the opening priority arm 43. A first drive groove 413 is provided in the middle of the arc surface of the safety arm body 411 for the first drive rod 54 to extend into; there are three first drive rods 54, which are distributed at equal angles from the center of the central control turbine 53. When the first drive rod 54 rotates forward and backward in the first drive groove 413, it will drive the drive block 412 to rotate forward and backward synchronously. When the first drive rod 54 drives the drive block 412 to press the end of the second safety arm 47 away from the opening priority arm 43, it will cause the end of the second safety arm 47 close to the opening priority arm 43 to tilt up, thereby disengaging from the matching state with the opening priority arm 43.

[0090] Furthermore, a press-in-place switch 55 is provided in the housing 10. When the driving block 412 presses the second safety arm 47 to a predetermined stroke, the press-in-place switch 55 is triggered by the driving block 412, at which time the central control motor 51 stops running, so that the first safety arm 41 maintains the state of pressing the second safety arm 47.

[0091] Furthermore, in some embodiments, in combination Fig.11 As shown, the outer opening arm 45 is integrally connected with the opening priority arm 43, and both are jointly formed at one end near the self-priming arm 33 to form a limiting half groove including two right-angled sides, so that the self-priming arm 33 can only rotate in one direction around the self-priming shaft 331. That is, when the sector-shaped tooth plate 31 is in the electric suction stroke, the limiting half groove can prevent the self-priming arm 33 from rotating in the opposite direction.

[0092] Specifically, the middle part of the self-priming arm 33 is rotatably connected to the fan-shaped tooth plate 31 through the self-priming shaft 331. The self-priming arm 33 includes a first self-priming support arm 332 and a second self-priming support arm 333, which are respectively arranged on opposite sides of the self-priming shaft 331. Therefore, the first self-priming support arm 332 can be limited by opening the priority arm 43, so that the second self-priming support arm 333 can lock the locking module 60. At the same time, opening the priority arm 43 can drive the first self-priming support arm 332 to rotate, so that the second self-priming support arm 333 can be separated from the track of abutting the locking module 60 in advance. That is, during the electric suction process and when the self-suction arm 33 has not yet abutted the driving arm 612, the inner opening arm 44 or the outer opening arm 45 can be pulled, and the first self-suction support arm 332 can be moved in advance by opening the priority arm 43, so that the self-suction arm 33 can rotate around the self-suction axis 331, so that the self-suction arm 33 can rotate more in advance, and then the second self-suction support arm 333 can be separated from the self-suction trajectory. At this time, even if the fan-shaped tooth plate 31 continues to rotate, the self-suction arm 33 will not touch the driving arm 612, thereby terminating the electric suction action. This design occupies a small space and has a quick response.

[0093] Therefore, when the vehicle door is in the electric door closing state (electric suction), if a person is at risk of being pinched by the vehicle door at this time, the opening priority arm 43 can be driven to rotate by pulling the inner handle or the outer handle, thereby terminating the electric door closing operation, realizing the anti-pinch opening priority function and ensuring safety during electric suction.

[0094] Furthermore, a self-priming arm guide wheel 334 is provided on a side of the first self-priming support arm 332 away from the self-priming shaft 331 , so that the opening priority arm 43 can adapt to the rotation of the self-priming arm 33 .

[0095] Combination Figure 4 , Figure 5 and Fig.11 As shown, the inner opening arm 44 includes a first inner branch arm 441 and a second inner branch arm 442. The first inner branch arm 441 is used to connect the cable, and the user can drive the inner opening arm 44 to rotate by pulling the cable. The second inner branch arm 442 is used to drive the opening priority arm 43 to rotate in one direction. Among them, the opening priority arm 43 is provided with a limiting groove 431, and the second inner branch arm 442 abuts against the bottom of the limiting groove 431, so that when the inner opening arm 44 rotates in a direction close to the opening priority arm 43, the inner opening arm 44 can drive the opening priority arm 43 to rotate; and when the inner opening arm 44 rotates in a direction away from the opening priority arm 43, the second inner branch arm 442 will be separated from the abutment with the opening priority arm 43, and can no longer drive the opening priority arm 43 to rotate.

[0096] Further, the inner opening arm 44 also includes a third inner branching arm 443. The second inner branching arm 442 and the third inner branching arm 443 are respectively arranged on the left and right sides of the first inner branching arm 441. A secondary opening arm 56 and a second driving rod 57 that can rotate independently relative to the central control turbine 53 are also provided on the side of the central control turbine 53 away from the first driving rod 54. The secondary opening arm 56 and the second driving rod 57 are fixedly connected at a preset angle, and here, the angle is an acute angle. A fan-shaped secondary rotating plate 58 is also provided on the side of the safety arm body 411 close to the secondary opening arm 56. The arc surface of the secondary rotating plate 58 is provided with a second driving groove 581 for the second driving rod 57 to extend into. The third inner branching arm 443 is used to drive the secondary opening arm 56 to rotate, so as to drive the safety arm body 411 to rotate, and the rotation direction is opposite to the rotation direction of the first safety arm 41 pressing the second safety arm 47, thereby releasing the pressing of the second safety arm 47.

[0097] Therefore, the utility model realizes the secondary opening function. When the door is in the locked state, the inner handle needs to be pulled twice to open the door lock. The first pull of the inner handle causes the inner opening arm 44 to rotate for the first time, thereby releasing the pressing state of the first safety arm 41 on the second safety arm 47, and switching the second safety arm 47 to abutting and cooperating with the opening priority arm 43, thereby realizing the central control unlocking; the inner handle is continued to be pulled to cause the inner opening arm 44 to rotate for the second time, thereby driving the opening arm 35 to rotate by driving the opening priority arm 43, so that the locking module 60 is unlocked, and the door can be opened at this time. By realizing the secondary execution opening function to open the door lock, the design cancels the original central control button and pull wire, and reduces the traditional safety button unlocking action.

[0098] Furthermore, a central control wire arm 582 is provided on the side of the secondary rotating plate 58 away from the safety arm body 411, and a side of the central control wire arm 582 away from the secondary rotating plate 58 is used to connect a cable. The central control wire arm 582 is used to drive the secondary rotating plate 58 to rotate, and the direction in which the third inner branch arm 443 drives the secondary rotating plate 58 to rotate is the same. That is, the central control unlocking can also be achieved by pulling the central control wire arm 582, which adds a central control unlocking method, enhances the protection of internal unlocking, and prevents passengers from being locked in the car.

[0099] Furthermore, combined with Fig.11 As shown, the locking module 60 also includes a child lock arm 65 rotatably connected to the housing 10. In this embodiment, the child lock arm 65 is arranged on the fixing seat 15. The edge of the inner opening arm 44 close to the locking module 60 extends outward to form a stop arm 444. The child lock arm 65 is used to abut against the stop arm 444 when it is rotated to a predetermined angle to rigidly limit the rotation of the inner opening arm 44. At this time, the inner opening arm 44 and even the inner handle are prevented from being pulled, and the child cannot open the door lock from inside the car, but it will not affect the person outside the car to pull the outer handle to drive the outer opening arm 45 to rotate, unlock the locking module 60, and open the door outside the car. This solution does not require opening holes in the body, has fewer parts, and saves space.

[0100] The automobile electric door integrated self-priming lock provided by the utility model realizes the two-in-one function of electric suction and electric opening by integrating the motor drive module 20, the transmission module 30, the clutch module 40, the central control module 50 and the locking module 60 into the shell 10, and also integrates the central control locking function. The overall integrated double inner push integrated design layout reduces 2 transmission modules and 2 pull wires compared to traditional automobile door locks, improves transmission efficiency, has a volume of 1 / 3 of the original structure, 2 / 3 of the number of parts, 1 / 2 of the cost, and saves 1 / 2 of the production time, thereby achieving power improvement, convenient management and installation, and reduced development costs. The electric suction output efficiency is increased by 20%, the direct cost is reduced by 50%, the door lock integration, work efficiency, and reliability are improved, and the comprehensive cost is greatly reduced, which has significant economic and social benefits.

[0101] The utility model provides an integrated structure of electric suction and electric opening for a self-priming door lock, in which the motor drive module 20 drives the sector tooth plate 31 to rotate in the first direction or the second direction, thereby realizing the electric suction and electric opening functions respectively. This design realizes power integration, saves a motor and a reduction box, saves 50% of space, and improves motor efficiency.

[0102] The central control and secondary opening structure of the self-priming door lock provided by the utility model controls the opening and closing of the second safety arm 47 through the central control module 50, realizes the clutch function between the opening priority arm 43 and the opening arm 35, realizes the one-button central control locking function, and can realize the secondary opening function, cancels the button release action, and saves buttons, pull wires, interior panel openings and layout space, which is convenient for users and satisfies user experience.

[0103] The opening priority structure of the self-priming door lock provided by the utility model is that when the motor drive module 20 drives the self-priming arm 33 to perform an electric suction action, the opening priority arm 43 can drive the first self-priming support arm 332 to rotate, so that the second self-priming support arm 333 is separated from the trajectory of abutting with the locking module 60 in advance, and the self-priming function can be cut off at any time when opened. The structure is simple and space-saving.

[0104] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
