[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] Reference below Figures 1 to 7 A door locking device 100 according to an embodiment of the present invention is described.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the door lock device 100 according to the first embodiment of the present invention includes: a housing 10 , an arm assembly, a locking arm 50 and a locking tongue 60 .

[0035] Among them, the arm assembly includes a power input part, the locking arm 50 has a first locking part 51, and the locking tongue 60 has a second locking part 61 that can be locked with the first locking part 51. When unlocking, the arm assembly is suitable for driving the locking arm 50 to rotate so that the first locking part 51 is disengaged from the second locking part 61.

[0036] According to the door lock device 100 of the embodiment of the present invention, the arm assembly can push the locking arm 50 to rotate so that the first locking portion 51 is disengaged from the second locking portion 61. In this way, not only can the door be unlocked quickly by the door lock device 100, but the door lock device 100 also has a simple structure, a fast response speed, and a high transmission efficiency.

[0037] Furthermore, the arm assembly includes an unlocking rocker arm 20, an auxiliary rocker arm 30 and a connecting arm 40. The unlocking rocker arm 20 is pivotally connected to the housing 10, the unlocking rocker arm 20 is formed as a power output member, the auxiliary rocker arm 30 is pivotally connected to the housing 10, the unlocking rocker arm 20 is suitable for pushing the auxiliary rocker arm 30 when unlocking, the connecting arm 40 is pivotally connected to the auxiliary rocker arm 30, and the connecting arm 40 is stop-fitted with the locking arm 50.

[0038] Specifically, the auxiliary rocker arm 30 is pivotally connected to the housing 10, the unlocking rocker arm 20 is adapted to push the auxiliary rocker arm 30 to rotate when unlocking, one end of the connecting arm 40 is pivotally connected to the auxiliary rocker arm 30, the locking arm 50 is pivotally connected to the housing 10, the locking arm 50 has a first locking portion 51, the locking tongue 60 is pivotally connected to the housing 10, the locking tongue 60 has a second locking portion 61 that can be locked with the first locking portion 51, and the unlocking rocker arm 20 can be driven along a first direction (such as Figure 2 and Figure 3 The locking arm 50 rotates in the counterclockwise direction as shown in FIG. 1 and pushes the locking arm 50 along the second direction (at this time, the movement trajectory of the locking arm 50 is Figure 2 The locking arm 50 slides along an arc extending clockwise around the rotation center line of the locking arm 50 described in the figure, so that the first locking portion 51 and the second locking portion 61 are disengaged.

[0039] In this way, not only the arm assembly is provided to make the power transmission in the door lock device 100 more stable and reliable, but also the matching relationship between the auxiliary rocker arm 30, the connecting arm 40 and the locking arm 50 is more stable, so that the working stability of the door lock device 100 is higher.

[0040] It should be noted that the first direction may be consistent with the counterclockwise direction in the drawings, and the third direction may be consistent with the clockwise direction in the drawings. The second direction refers to the direction in which the locking arm 50 moves away from the locking tongue 60, and the fourth direction refers to the direction in which the locking arm 50 moves toward the locking tongue 60.

[0041] When the second locking portion 61 of the lock tongue 60 is in abutment with the first locking portion 51 of the lock arm 50, the door lock is in a locked state. When the first locking portion 51 is disengaged from the second locking portion 61, the door lock is in an unlocked state. The avoidance groove on the housing 10 is used to guide the movement of the first stop pin 52. The unlocking rocker arm 20 is driven to move in the first direction, and the unlocking rocker arm 20 moving in the first direction can push the auxiliary rocker arm 30 to rotate, so that the auxiliary rocker arm 30 can push the first stop pin 52 to slide in the second direction through the connecting arm 40. Figure 1As shown, the unlocking rocker arm 20 has a first stop portion 21, the auxiliary rocker arm 30 has a second stop pin 31 that cooperates with the first stop portion 21, the connecting arm 40 has a second stop portion 41, the first stop pin 52 is formed as a first stop pin 52, and the second stop pin 31 and the first stop pin 52 fall into the space defined by the first stop portion 21 and the second stop portion 41.

[0042] Specifically, a first stop portion 21 is formed on the arm of the unlocking rocker arm 20 facing the second stop pin 31 of the auxiliary rocker arm 30, and the first stop portion 21 can be spaced apart from the second stop pin 31 in the locked state. When unlocking, the unlocking rocker arm 20 rotates in the first direction and pushes the auxiliary rocker arm 30 to rotate in the second direction. At this time, the first stop portion 21 always pushes against the second stop pin 31. The connecting arm 40 moves under the drive of the auxiliary rocker arm 30 and pushes against the first stop pin 52 of the locking arm 50 through the second stop portion 41 to transmit power to the locking arm 50. The locking arm 50 is unscrewed so that the second locking portion 61 of the locking tongue 60 and the locking arm 50 are unlocked, and the locking tongue 60 is freed from the constraint of the locking arm 50, thereby achieving rapid unlocking.

[0043] Therefore, the rotation of the locking arm 50 is driven by the abutment cooperation between the first stop portion 21 and the second stop pin 31, and the second stop portion 41 and the first stop pin 52, so that the power transmission during the unlocking process is more stable and the cooperation between the multiple parts of the door lock device 100 is more reliable, thereby improving the working stability of the door lock device 100.

[0044] exist Figure 1 In the specific embodiment shown, the arm assembly is located on one side of the shell 10, and the locking arm 50 and the locking tongue 60 are located on the other side of the shell 10. The shell 10 has an avoidance groove, and the locking arm 50 passes through the avoidance groove to stop with the locking arm 50.

[0045] In this way, the unlocking rocker arm 20, the auxiliary rocker arm 30 and the connecting arm 40 are arranged on one side of the shell 10 (i.e., inside the shell 10), and the lock tongue 60 and the locking arm 50 are arranged on the other side of the shell 10 (i.e., outside the shell 10 in the direction of the lock tongue 60). This not only avoids interference between the various components of the door lock device 100, but also makes the spatial layout of the door lock device 100 more reasonable, and can prevent dust and foreign matter from directly entering the door lock device 100, thereby improving the use stability of the door lock device 100 and making the layout of the door lock device 100 on the vehicle simpler and more convenient.

[0046] In addition, the first stop pin 52 of the locking arm 50 extends into the shell 10 to cooperate with the second stop portion 41 of the connecting arm 40, and in the process of pushing the locking arm 50 to rotate through the second stop portion 41, the movement of the locking arm 50 is guided by the avoidance groove to make the rotation of the locking arm 50 smoother.

[0047] like Figures 2 to 4 As shown, the unlocking rocker arm 20 and the locking arm 50 are pivoted to the housing 10 through the first pivot axis a, the auxiliary rocker arm 30 is pivoted to the housing 10 through the second pivot axis b, the auxiliary rocker arm 30 and the connecting arm 40 are pivoted to each other through the third pivot axis c, and the lines connecting the projections of the first pivot axis a, the second stop pin 31, the second pivot axis b, the third pivot axis c, and the first stop pin 52 in the vertical direction form a closed loop.

[0048] In this way, not only the projected connecting line of the first pivot axis a, the second pivot axis b, the third pivot axis c, the first stop pin 52 and the second stop pin 31 forms a closed loop, so that the distribution of each part in the housing 10 is more reasonable and the structure of the door lock device 100 is more compact; and the power is transmitted from the unlocking rocker arm 20 located on the first pivot axis a to the locking arm 50 located on the second pivot axis b, thereby driving the vehicle door lock to unlock, the power transmission path of the closed loop can effectively reduce the power loss, so that the response speed of locking or unlocking the vehicle door lock is faster; and the first locking portion 51 and the second stop portion 41 are separated on the locking arm 50, which can avoid interference between the first locking portion 51 and the connecting arm 40, so that the working stability of the door lock device 100 is higher.

[0049] It should be noted that the first pivot axis a can be an unlocking rocker pin, the second pivot axis b can be an auxiliary rocker pin, the lock tongue 60 is pivotally connected to the shell 10 through the lock tongue pin g, and the first pivot axis a, the second pivot axis b and the lock tongue pin g are all fixedly connected to the shell 10 through a mounting column or a mounting sleeve provided on the shell 10.

[0050] Furthermore, the first locking portion 51 is located outside the closed loop. Thus, the first locking portion 51 on the locking arm 50 is located outside the closed loop, so that the first locking portion 51 can rotate to a greater extent after being subjected to force, thereby achieving a better unlocking effect of the door lock device 100 and avoiding the locking arm 50 from getting stuck and causing the car lock to be unable to be opened.

[0051] exist Figure 1 In the specific embodiment shown, the door lock device 100 also includes an electric drive component 70, which is fixedly connected to the shell 10. The electric drive component 70 has a retractable pull wire 71. The pull wire 71 is connected to the unlocking rocker arm 20 through a pivot seat 80. The pivot seat 80 is pivotally connected to the unlocking rocker arm 20, and the pull wire 71 is fixedly connected to the pivot seat 80.

[0052] In this way, when the electric drive component 70 is energized to tighten or loosen the pull wire 71, the pivot seat 80 can drive the unlocking rocker arm 20 to rotate under the pull of the pull wire 71, and during the tightening or loosening process of the pull wire 71, the pivot seat 80 can rotate freely relative to the unlocking rocker arm 20, so that the angle between the pull wire 71 and the unlocking rocker arm 20 can change reasonably, thereby preventing interference between the pull wire 71 and the unlocking rocker arm 20, and making the door lock device 100 more stable.

[0053] like Figure 5 , Figure 6 and Figure 7 As shown, the pivoting seat 80 includes a pivoting column 81 and a threading column 82 connected to one end of the pivoting column 81, the threading column 82 has a threading hole for the pull wire 71 to pass through and fix, and the other end of the pivoting column 81 has a limit buckle 811, the limit buckle 811 passes through the unlocking rocker arm 20 and together with the threading column 82, the pivoting column 81 is axially positioned on the unlocking rocker arm 20. In this way, not only the connection between the pivoting seat 80 and the unlocking rocker arm 20 is made more stable to improve the stability of the relative rotation between the two, but also the fixation of the pull wire 71 on the pivoting seat 80 is made more stable, so that the transmission between the electric drive member 70 and the unlocking rocker arm 20 is more stable.

[0054] exist Figure 5 In the specific embodiment shown, the electric drive component 70 includes: a rotating motor 72 and a winding component 73, the rotating motor 72 includes a motor body 721 and a motor shaft 722, the motor body 721 is fixed to the housing 10, the winding component 73 is fixedly connected to the motor shaft 722, the other end of the pull wire 71 is fixedly connected to the winding component 73, the rotating motor 72 can rotate and wind the pull wire 71 around the winding component 73 or the motor shaft 722 to tighten the pull wire 71.

[0055] Therefore, by setting the winding member 73, the pull wire 71 can be wound on the winding member 73 to limit the winding area of ​​the pull wire 71, thereby preventing the pull wire 71 from being wound around other components and causing the rotating motor 72 to shut down, thereby preventing the electric drive component 70 from being damaged and increasing the service life of the electric drive component 70.

[0056] Reference Figure 5 As shown, the winding member 73 includes a shaft sleeve 731 and a plastic sleeve 732 . The shaft sleeve 731 is fixed in the plastic sleeve 732 . The motor shaft 722 has a knurled portion. The shaft sleeve 731 is sleeved on the motor shaft 722 and has an interference fit with the knurled portion. The pull wire 71 is connected to the plastic sleeve 732 .

[0057] In this way, the motor shaft 722 and the sleeve 731 connected by interference fit make the connection between the motor shaft 722 and the winding member 73 tighter and more reliable, and the plastic sleeve 732 is fixedly connected by the sleeve 731 to prevent the plastic sleeve 732 and the pull wire 71 from falling off the motor shaft 722, thereby improving the working stability of the electric drive member 70.

[0058] It should be noted that the knurled portion refers to the straight or mesh-shaped knurling pressed out on the motor shaft 722 by a knurling roller. By providing the knurled portion, the surface friction coefficient of the motor shaft 722 is made higher, so that the connection between the motor shaft 722 and the sleeve 731 is more stable, and the probability of shaking or slipping of the sleeve 731 when rotating around the motor shaft 722 is lower.

[0059] Furthermore, the pull wire 71, the pivot seat 80, and the plastic sleeve 732 are formed into an integral part by injection molding. In this way, it is not only convenient to assemble the electric drive member 70, but also the integrally formed pull wire 71, the pivot seat 80, and the plastic sleeve 732 have a higher structural strength, which can extend the service life of the electric drive member 70 and the pivot seat 80.

[0060] Here, it can be understood that the motor shaft 722 of the rotating motor 72 is rolled to form a knurled portion, the plastic sleeve 732, the pull wire 71 and the rotating seat are injection molded as one piece, and the sleeve 731 is arranged on the knurled portion and connected to the plastic sleeve 732. The sleeve 731 is located between the motor shaft 722 and the plastic sleeve 732. The plastic sleeve 732 and one end of the pull wire 71 are fixed to the motor shaft 722 by the sleeve 731 that is interference fit with the knurled portion, and the other end of the pull wire 71 is connected to the pivot seat 80, so that the pull wire 71 can be driven by the rotating motor 72 to be wound around the plastic sleeve 732 and drive the pivot seat 80 to rotate.

[0061] Optionally, the shaft sleeve 731 is a metal part, the cross section of the outer surface of the shaft sleeve 731 is non-circular, and the plastic sleeve 732 has a non-circular inner hole that is interference-fitted with the shaft sleeve 731. In this way, the shaft sleeve 731 with a metal structure is not only more firmly and reliably connected to the motor shaft 722, but also the non-circular inner hole can make the shaft sleeve 731 and the motor shaft 722 have better synchronous rotation performance, and the winding effect of the pull wire 71 is better.

[0062] According to some embodiments of the present invention, the door lock device 100 further includes: an auxiliary rocker arm reset component d, a locking arm reset component e and a lock tongue reset component f, wherein one end of the auxiliary rocker arm reset component d is connected to the housing 10 and the other end is connected to the unlocking rocker arm 20.

[0063] Among them, the auxiliary rocker arm reset member d often drives the unlocking rocker arm 20 to move in a second direction opposite to the first direction, one end of the locking arm reset member e is connected to the housing 10 and the other end is connected to the connecting arm 40, the locking arm reset member e often drives the locking arm 50 and the connecting arm 40 to move, so that the first stop pin 52 of the locking arm 50 slides in a fourth direction opposite to the second direction, one end of the lock tongue reset member f is connected to the housing 10 and the other end is connected to the lock tongue 60, the lock tongue reset member f often drives the lock tongue 60 to rotate so that the first locking portion 51 is locked and matched with the second locking portion 61.

[0064] Therefore, after completing the unlocking action, the unlocking rocker arm 20, the connecting arm 40 and the auxiliary rocker arm 30 can return to their initial positions under the action of the unlocking rocker arm 20, the locking arm 50 can return to its initial position under the action of the locking arm reset piece e, and the lock tongue 60 can return to its initial position under the action of the lock tongue reset piece f, thereby returning the vehicle door lock to a locked state, thereby improving the working stability of the door lock device 100 and further improving the safety of vehicle use.
