Technical Field
[0001] This application relates to the field of automotive parts technology, specifically to a door lock device and a vehicle. Background Technology
[0002] With economic development and technological advancements, automobiles have become an indispensable means of transportation, and car door lock systems have become increasingly sophisticated. However, in most existing door lock systems, the inward and outward opening components are linked and controlled by the same part. Driving the inward opening component can affect the outward opening component, causing it to twitch, impacting user experience and the layout of both the inward and outward door handles. Summary of the Invention
[0003] The purpose of this application is to provide a door lock device and a vehicle, wherein the inward opening movement and the outward opening movement of the door lock device are separated to ensure that the inward opening stroke and the outward opening stroke do not affect each other.
[0004] To achieve the objectives of this application, the following technical solution is provided:
[0005] In a first aspect, this application provides a door lock device, including a bolt, a locking arm, a cooperating rocker, a cooperating rocker arm, and an inward opening assembly. The locking arm is used to engage with the bolt. When the cooperating rocker moves, it drives the cooperating rocker arm to rotate. The inward opening assembly is connected to the cooperating rocker arm. When the inward opening assembly is unlocked, the inward opening assembly drives the cooperating rocker arm to rotate, and the cooperating rocker arm drives the locking arm to rotate, so that the locking arm separates from the bolt, and the cooperating rocker does not move.
[0006] In one embodiment, the door lock device further includes an outward opening component connected to the cooperating rocker arm. When the outward opening component is unlocked, it drives the cooperating rocker arm to rotate, thereby causing the cooperating rocker arm to rotate.
[0007] In one embodiment, the locking arm, the cooperating rocker, and the cooperating rocker arm all rotate around a first rotating shaft. The cooperating rocker is located on the side of the cooperating rocker arm opposite to the locking arm. The cooperating rocker includes a rotating part and a pushing part connected to each other. The cooperating rocker arm includes a first flange. The rotating part is connected to the first rotating shaft. The rotating part rotates to drive the pushing part to connect with the first flange. The pushing part pushes the first flange to make the cooperating rocker arm rotate.
[0008] In one embodiment, the mating rocker arm further includes a second flange, the minimum distance of the second flange to the first rotating shaft is greater than the maximum distance of the first flange to the first rotating shaft, the pushing part is independent of the second flange, and the inward opening component is connected to the second flange to rotate the mating rocker arm by pushing the second flange.
[0009] In one embodiment, the first flange, the second flange, and the pushing part are all located on the same side of the rotating part, and the first flange and the second flange are spaced apart in the circumferential direction of the cooperating rocker arm. The pushing part is located between the first flange and the second flange, and when the inner opening assembly pushes the second flange to rotate, the second flange does not contact the pushing part.
[0010] In one embodiment, the door lock device further includes a push rod and a locking link connected by transmission. The push rod has a first position and a second position. The locking link is used to drive the push rod to switch between the first position and the second position. In the first position, the cooperating rocker arm drives the locking arm to rotate through the push rod, so that the locking arm is separated from the bolt. In the second position, the cooperating rocker arm drives the push rod to rotate, and the locking arm does not rotate.
[0011] In one embodiment, the locking link includes an upper locking link and a lower locking link that are connected by transmission. The upper locking link rotates about a second rotating shaft, and the lower locking link rotates about a third rotating shaft. The rotation of the upper locking link drives the rotation of the lower locking link. The lower locking link is connected to the push rod, and the rotation of the lower locking link drives the push rod to switch between a first position and a second position.
[0012] In one embodiment, the door lock device further includes a drive member, the drive member including a worm gear, and the upper locking link including a rack portion, the worm gear and the rack portion engaging in gear transmission.
[0013] In one embodiment, the door lock device further includes a rotating arm and a transmission component connected by transmission. The rotating arm is used to connect with a key, and the transmission component is connected with the upper locking link. The rotating arm rotates to drive the transmission component to move, and the transmission component drives the upper locking link to rotate.
[0014] In one embodiment, the door lock device further includes a mounting plate, the latch and the locking arm are mounted on the mounting plate, the first rotating shaft is connected to the mounting plate, and the axis of the first rotating shaft is perpendicular to the mounting plate, and the direction in which the key is inserted into the rotating arm is perpendicular to the axis of the first rotating shaft.
[0015] In one embodiment, the inward-opening assembly includes an inward-opening rocker arm that rotates about a fourth pivot axis. The rotation of the inward-opening rocker arm connects to the mating rocker arm and drives the mating rocker arm to rotate.
[0016] In one embodiment, the inward-opening rocker arm further includes a third flange. During the process of the push rod switching from the first position to the second position, the inward-opening rocker arm rotates so that the third flange connects to the upper locking link. The inward-opening rocker arm drives the upper locking link to rotate through the third flange. The rotation of the upper locking link causes the push rod to switch from the second position to the first position.
[0017] Secondly, this application also provides a vehicle, including a door and a door lock device as described in any one of the embodiments of the first aspect, the door lock device being installed inside the door.
[0018] The door lock device provided in this application features a separate mating rocker arm and a mating rocker arm, with the mating rocker arm connected to the inward opening component. When the inward opening component drives the mating rocker arm to rotate, the mating rocker arm remains unaffected. This effectively separates the inward and outward opening movements of the door lock device, ensuring that the inward and outward opening strokes do not interfere with each other. At the same time, the overall unlocking action can be completed jointly by the mating rocker arm and the locking arm. Therefore, this door lock device ensures both the independence of the movement stroke and the versatility of the moving parts, exhibiting good functional stability and platform universality.

Detailed Implementation
[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0033] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.
[0034] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0035] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0036] The door lock device provided in this application can be used in vehicles, specifically gasoline-powered vehicles or new energy electric vehicles, to help vehicles achieve the functions of opening and locking doors. Specifically, the door lock device includes an inward opening component, an outward opening component, and a central control component, with the inward and outward opening components being linked. The inward opening component can be connected to the vehicle's inner door handle, allowing passengers to drive the inner door handle from inside the vehicle's passenger compartment, which in turn triggers the inward opening component to unlock and open the door. The outward opening component can be connected to the vehicle's outer door handle, allowing passengers to drive the outer door handle from outside the vehicle's passenger compartment, which in turn triggers the outward opening component to unlock and open the door. The central control component can be used to switch the door lock device between a locked state and an unlocked state. In the locked state, the door lock device is locked, and passengers cannot unlock or open the door from either inside or outside the passenger compartment using either the inward or outward opening component. In the unlocked state, the door lock device is unlocked, and passengers can unlock or open the door from either inside or outside the passenger compartment by driving either the inward or outward opening component.
[0037] In one implementation method, please refer to Figure 1 The door lock device 100 includes a bolt 21, a locking arm 22, a cooperating rocker 23, and a cooperating rocker arm 24. The locking arm 22 rotates around a first pivot 41 and is used to engage with the bolt 21. Both the cooperating rocker 23 and the cooperating rocker arm 24 rotate around the first pivot 41, and the cooperating rocker 23 is connected to the cooperating rocker arm 24. The cooperating rocker arm 24 rotates and drives the locking arm 22 to rotate around the first pivot 41, so that the locking arm 22 and the bolt 21 change from being engaged to being disengaged. The outward opening component is connected to the cooperating rocker 23. When the outward opening component is unlocked, the outward opening component drives the cooperating rocker 23 to rotate, thereby driving the cooperating rocker arm 24 to rotate. The inward opening component is connected to the cooperating rocker arm 24. When the inward opening component is unlocked, the inward opening component drives the cooperating rocker arm 24 to rotate, and the cooperating rocker 23 does not move.
[0038] Specifically, the door lock device 100 can be installed on the vehicle body or the door. The door lock device 100 is used to cooperate with a latch to close or lock the door. The door lock device 100 includes a mounting housing 13, a latch 21 and a locking arm 22, both mounted on the mounting housing 13, and a first rotating shaft 41 passing through the mounting housing 13. The door lock device 100 also includes a latch 21 shaft, around which the latch 21 rotates; the latch 21 shaft also passes through the mounting housing 13, and the axis of the latch 21 shaft is parallel to the axis of the first rotating shaft 41. The latch 21 is disposed on the first rotating shaft 41 and is capable of rotating clockwise or counterclockwise around the first rotating shaft 41. The locking arm 22 is capable of rotating clockwise or counterclockwise around the first rotating shaft 41. The latch 21 includes a locking groove for receiving the latch. For example, when the car door is gently closed, the latch can move into the locking groove. As the car door gradually closes, the latch can push the bolt 21 to rotate by connecting with the wall of the locking groove. The bolt 21 is then held in place by the locking arm 22, so that the latch cannot come out of the locking groove, thus achieving door closure.
[0039] In one embodiment, both the latch 21 and the locking arm 22 are connected to a return spring (not shown in the figure). The latch 21 rotates counterclockwise under the action of the return spring, while the locking arm 22 rotates clockwise under the action of the return spring. During locking, the latch drives the latch 21 to rotate clockwise as the door closes. When it reaches the fully locked position, the locking arm 22, due to the potential energy of the clockwise rotation, locks the latch 21 in the fully locked position. Of course, in other embodiments, the rotation process can be reversed. It is understood that the rotation direction of the latch 21 and the locking arm 22 is not limited, as long as the rotation method achieves the locking action.
[0040] In one implementation method, please refer to Figure 1 and Figure 2The mating rocker arm 24 and the mating rocker arm 23 are mounted on the side of the mounting housing 13 facing away from the locking arm 22. Optionally, the mating rocker arm 23 is mounted on the side of the mating rocker arm 24 facing away from the mounting housing 13. At least part of the mating rocker arm 24 can extend through the mounting housing 13 to the position of the locking arm 22, so that when the mating rocker arm 24 rotates, it can also drive the locking arm 22 to rotate accordingly. The mating rocker arm 23 is directly or indirectly connected to the outer opening component. When the outer opening component moves, it can drive the mating rocker arm 23 to rotate around the first rotating shaft 41. The outer rocker arm can then drive the mating rocker arm 24 to rotate accordingly, ultimately driving the locking arm 22 to rotate and unlock. The mating rocker arm 24 is directly or indirectly connected to the inner opening component. When the inner opening component moves, it can drive the mating rocker arm 24 to rotate around the first rotating shaft 41, thereby driving the mating rocker arm 24 to rotate accordingly, ultimately driving the locking arm 22 to rotate and unlock. Furthermore, during the movement of the inner opening component, the cooperating rocker arm 23 can be fixed relative to the first rotating shaft 41, i.e., remain stationary, so that the outer opening component will not be linked by the movement of the inner opening component. It can be understood that the cooperating rocker arm 23 is independent of the cooperating rocker arm 24 mentioned above, that is, when the inner opening component drives the cooperating rocker arm 24, the cooperating rocker arm 24 will not drive the cooperating rocker arm 23 in the opposite direction.
[0041] The door lock device 100 provided in this application has separate mating rocker arm 23 and mating rocker arm 24, and the mating rocker arm 24 is connected to the inward opening component. When the inward opening component drives the mating rocker arm 24 to rotate, the mating rocker arm 23 is not affected. This can effectively separate the inward opening movement and the outward opening movement of the door lock device 100, ensuring that the inward opening stroke and the outward opening stroke do not affect each other. At the same time, the overall unlocking action can be completed by the mating rocker arm 24 and the locking arm 22. Therefore, the door lock device 100 not only ensures the independence of the movement stroke but also meets the universality of the moving parts, and has good functional stability and platform universality.
[0042] In one implementation method, please refer to Figure 1 The door lock device 100 also includes an upper housing 11 and a lower housing 12, which are connected together. The upper housing 11 and lower housing 12 may be equipped with a pivot and a return spring. Both the outward opening assembly and the inward opening assembly can be installed within the space formed after the upper housing 11 and lower housing 12 are connected, and their respective movement functions are achieved through the pivot and return spring. The upper housing 11 and lower housing 12 can also be connected to a mounting shell 13 respectively.
[0043] In one implementation method, please refer to Figure 1 The door lock device 100 also includes a fixing plate 14, and the first rotating shaft 41 and the bolt 21 shaft are fixed to the mounting housing 13 by the fixing plate 14.
[0044] In one implementation method, please refer to Figure 2 and Figure 3The rocker arm 23 is located on the side of the rocker arm 24 facing away from the locking arm 22. The rocker arm 23 includes a rotating part 231 and a pushing part 232 connected to each other. The rocker arm 24 includes a first flange 241. The rotating part 231 is connected to the first rotating shaft 41. The rotation of the rotating part 231 drives the pushing part 232 to connect with the first flange 241. The pushing part 232 pushes the first flange 241 to make the rocker arm 24 rotate.
[0045] Specifically, the rotating part 231 and the pushing part 232 are an integral structure. The rotating part 231 is sleeved on the outer periphery of the first rotating shaft 41, thereby achieving a rotatable connection. The pushing part 232 is connected to the outer periphery of the rotating part 231, and the outward-opening component can connect to the end of the mating rocker arm 23 away from the pushing part 232. The first flange 241 is the part of the mating rocker arm 24 that is bent away from the mounting shell 13. Thus, when the mating rocker arm 23 is located on the side of the mating rocker arm 24 that is away from the mounting shell 13, the pushing part 232 can be blocked by the first flange 241 during its movement, thereby causing the mating rocker arm 24 to rotate by pushing the first flange 241.
[0046] By setting the pusher 232 and the first flange 241 to cooperate, when the driving rocker arm 23 is rotated, the rocker arm 24 can rotate in the same direction under the cooperation of the pusher 232 and the first flange 241.
[0047] In one implementation method, please refer to Figure 2 and Figure 3 The rocker arm 24 also includes a second flange 242. The minimum distance between the second flange 242 and the first rotating shaft 41 is greater than the maximum distance between the first flange 241 and the first rotating shaft 41. The pushing part 232 is spaced apart from the second flange 242. The inner opening component is connected to the second flange 242 so that the rocker arm 24 can be rotated by pushing the second flange 242.
[0048] Specifically, the second flange 242 and the first flange 241 can be staggered in the diametrical direction of the first rotating shaft 41. That is, the distance from the second flange 242 to the first rotating shaft 41 is greater than the distance from the first flange 241 to the first rotating shaft 41, while the distance from the pushing part 232 to the first rotating shaft 41 can be equal to the distance from the first flange 241 to the first rotating shaft 41. Thus, when the pushing part 232 rotates clockwise or counterclockwise, it can only connect with the first flange 241 and cannot connect with the second flange 242. The minimum distance from the second flange 242 to the first rotating shaft 41 should be understood as the straight-line distance between the point on the second flange 242 closest to the outer peripheral wall of the first rotating shaft 41 and the outer peripheral wall; similarly, the maximum distance from the first flange 241 to the first rotating shaft 41 is the straight-line distance between the point on the first flange 241 closest to the outer peripheral wall of the first rotating shaft 41 and the outer peripheral wall.
[0049] The second flange 242 can be used to connect with the inner opening component, which pushes the second flange 242 to rotate the cooperating rocker arm 24. Understandably, assuming the pushing part 232 can connect with the first flange 241 and drive the cooperating rocker arm 24 to rotate when rotating clockwise, the inner opening mechanism can also unlock by pushing the second flange 242 to rotate clockwise and drive the cooperating rocker arm 24 to rotate. However, when the second flange 242 is driven, it will not connect with the pushing part 232, so the cooperating rocker arm 23 can be fixed relative to the first pivot 41.
[0050] By setting the first flange 241 and the second flange 242 to be staggered, when the inner opening component drives the rocker arm 24, the rocker arm 24 will not drive the rocker lever 23, thus ensuring the independence of the outer opening component.
[0051] In one implementation method, please refer to Figure 2 and Figure 3 The first flange 241, the second flange 242 and the pushing part 232 are all located on the same side of the rotating part 231, and the first flange 241 and the second flange 242 are spaced apart in the circumferential direction of the rocker arm 24. The pushing part 232 is located between the first flange 241 and the second flange 242. When the inner opening component pushes the second flange 242 to rotate, the second flange 242 does not contact the pushing part 232.
[0052] Specifically, since the rocker arm 23 and the rocker arm 24 are stacked, at least a portion of the rocker arm 24 coincides with the projection of the pusher 232 on the axial direction of the first rotating shaft 41. The first flange 241 and the second flange 242 are connected to the portion where the projections coincide. It can be understood that the first flange 241 and the second flange 242 are spaced apart circumferentially on the rocker arm 24, meaning the first flange 241 and the second flange 242 are not collinear in the radial direction of the first rotating shaft 41. Therefore, the pusher 232 can be located between the first flange 241 and the second flange 242. Furthermore, when the distances of the first flange 241 and the second flange 242 from the first rotating shaft 41 are different, the rotation of the pusher 232 can push the first flange 241 but not the second flange 242.
[0053] By adopting the above-mentioned configuration, it is possible to avoid the rocker arm 23 moving to the position of the second flange 242 when it moves radially in the first rotating shaft 41 due to looseness, thereby affecting the second flange 242 and ensuring the stability of the door lock device 100 in a vibrating environment.
[0054] In one implementation method, please refer to Figure 2 and Figure 3The door lock device 100 also includes a push rod 25 and a locking link 26 connected by transmission. The push rod 25 has a first position and a second position. The locking link 26 is used to drive the push rod 25 to switch between the first position and the second position. In the first position, the rocker arm 24 drives the locking arm 22 to rotate through the push rod 25. In the second position, the rocker arm 24 drives the push rod 25 to rotate, and the locking arm 22 does not rotate.
[0055] Specifically, the locking link 26 can be located on the side of the mounting housing 13 facing away from the bolt 21, and the locking link 26 can rotate about the bolt 21 axis. The push rod 25 is generally long and thin, with one end connected to the locking link 26 and the other end located on the mating rocker arm 24, and at least part of the push rod 25 is located on the side of the outward-opening push rod 25 facing away from the mating rocker arm 24. Optionally, one end of the push rod 25 passes through the mating rocker arm 24 and the mounting housing 13 and is located near the locking arm 22. When the mating rocker arm 24 rotates, it can drive the push rod 25 to move accordingly, so that the push rod 25 can push the locking arm 22 to rotate, thereby unlocking.
[0056] In one implementation method, please refer to Figure 4 and Figure 5 The push rod 25 includes a first mating part 251, and the locking arm 22 includes a second mating part 221. After the rocker arm 24 rotates to drive the push rod 25 to rotate, the first mating part 251 and the second mating part 221 are connected. The rocker arm 24 drives the second mating part 221 through the first mating part 251, so that the locking arm 22 rotates to separate from the latch 21. Specifically, the first mating part 251 and the second mating part 221 may each have a smooth contact surface. After the push rod 25 rotates to the point where the first mating part 251 and the second mating part 221 contact, their contact surfaces can be connected in parallel. As the push rod 25 continues to rotate, it can drive the locking arm 22 to rotate.
[0057] In one implementation method, please refer to Figure 2 and Figure 3 The rocker arm 24 has a receiving groove 243, and the first mating part 251 is housed in the receiving groove 243. The rocker arm 24 drives the first mating part 251 to move through the wall of the receiving groove 243. Specifically, the receiving groove 243 is formed on the edge of the rocker arm 24 and extends toward the first rotating shaft 41 to form a "U"-shaped groove 333. The first mating part 251 is housed in the receiving groove 243 and extends through the receiving groove 243 to the plane where the locking arm 22 is located. After the rocker arm 24 rotates, the wall of the receiving groove 243 can push the first mating part 251 to drive the push rod 25 to rotate together, and after the first mating part 251 rotates until it contacts the second mating part 221, it pushes the locking arm 22.
[0058] In one embodiment, in the first position, the first mating part 251 is positioned relatively close to the first rotating shaft 41 within the receiving groove 243, cooperating with the rocker arm 24 to drive the push rod 25 to achieve the movement process described in the above embodiment. During the process of the push rod 25 switching from the first position to the second position, the locking link 26 rotates to drive the push rod 25 to move axially along the push rod 25, thereby positioning the first mating part 251 relatively far away from the first rotating shaft 41 within the receiving groove 243. When the rocker arm 24 drives the push rod 25 to rotate, the first mating part 251 cannot contact the second mating part 221 through rotation, so the push rod 25 cannot drive the locking arm 22 to rotate to unlock. Understandably, since the locking arm 22 and the rocker arm 24 are coaxial, when the line connecting the farthest point of the locking arm 22 to the first rotating shaft 41 is less than the line connecting the push rod 25 to the first rotating shaft 41, the passenger cannot drive the locking arm 22 by controlling the push rod 25 to rotate.
[0059] In one implementation method, please refer to Figure 3 and Figure 9 The locking link 26 includes an upper locking link 26A and a lower locking link 26B that are connected by transmission. The upper locking link 26A rotates around the second rotating shaft 42, and the lower locking link 26B rotates around the third rotating shaft 43. The rotation of the upper locking link 26A drives the lower locking link 26B to rotate. The lower locking link 26B is connected to the push rod 25. The rotation of the lower locking link 26B drives the push rod 25 to switch between the first position and the second position, which cooperates with the rotation of the rocker arm 24 and drives the push rod 25 to rotate around the lower locking link 26B.
[0060] Specifically, the axis of the second rotating shaft 42 can intersect with the axis of the first rotating shaft 41, and the upper locking link 26A can be connected to other driving components. The third rotating shaft 43 can be the bolt 21 shaft in the above embodiment, and the lower locking link 26B is located on the side of the mounting housing 13 facing away from the bolt 21. Further, the lower locking link 26B can include a first driven end 26B1, and the upper locking link 26A can include a first driving end 26A1. The first driving end 26A1 can be a groove 333 structure. The first driven end 26B1 can be spherical and housed within the first driving end 26A1. When the upper locking link 26A rotates, the first driving end 26A1 drives the first driven end 26B1, thereby realizing the rotation of the lower locking link 26B. It can be understood that when the upper locking link 26A rotates clockwise or counterclockwise, the lower locking link 26B can also rotate counterclockwise or clockwise accordingly.
[0061] In one implementation method, please refer to Figure 2 and Figure 4The push rod 25 includes a connecting portion 252, which is the end of the push rod 25 away from the first mating portion 251. The connecting portion 252 is rotatably connected to the lower locking link 26B, meaning the push rod 25 can rotate around the connecting portion 252. Understandably, when the rocker arm 24 drives the push rod 25 to rotate, the push rod 25 can rotate accordingly via the connecting portion 252. Furthermore, during the rotation of the lower locking link 26B, the lower locking link 26B drives the push rod 25 to move. The push rod 25 can rotate relative to the lower locking link 26B under the constraint of the receiving groove 243, thereby maintaining its movement within the receiving groove 243. Optionally, the connecting portion 252 is connected to the end of the lower locking link 26B away from the first driven end 26B1 to obtain the maximum rotational stroke.
[0062] In one implementation method, please refer to Figure 3 and Figure 6 The door lock device 100 also includes a drive member 27, which includes a worm gear 271 and an upper locking link 26A including a rack portion 26A2. The worm gear 271 and the rack portion 26A2 are meshed for transmission. Specifically, the drive member 27 can be a motor, and the worm gear 271 passes through the motor's shaft. The rack portion 26A2 is located at the end of the upper locking link 26A away from the first drive end 26A1, and the rack portion 26A2 is sawtooth-shaped to cooperate with the worm gear 271. The drive member 27 drives the upper locking link 26A to rotate by driving the worm gear 271 to rotate in both directions.
[0063] In one embodiment, the push rod 25, locking linkage 26, and drive component 27 described above can all be parts of the central control assembly. It is understood that the user can indirectly control the push rod 25 to move between a first position and a second position by controlling the drive component 27 via the vehicle's infotainment system. Ultimately, this controls the door lock device 100 to be in either a locked or unlocked state.
[0064] In one implementation method, please refer to Figure 6 and Figure 7 The door lock device 100 also includes a rotating arm 28 and a transmission member 29 connected by transmission. The rotating arm 28 is used to connect with a key, and the transmission member 29 is connected to the upper locking link 26A. The rotating arm 28 rotates to drive the transmission member 29 to move, and the transmission member 29 drives the upper locking link 26A to rotate.
[0065] Specifically, the rotating arm 28 can cooperate with a key. By inserting the key into the rotating arm 28 and turning the key, the rotation of the rotating arm can be controlled. After rotation, the rotating arm can drive the transmission component 29 to swing accordingly. Furthermore, since the transmission component 29 is connected to the upper locking link 26A, it can drive the upper locking link 26A to rotate.
[0066] In one implementation method, please refer to Figure 6and Figure 7 The transmission component 29 rotates around the transmission shaft. The transmission component 29 includes a second driving end 291, and the upper locking link 26A includes a second driven end 26A3. The second driving end 291 can be a groove structure 333. The second driven end 26A3 can be cylindrical and housed within the second driving end 291. When the transmission component 29 rotates, the second driving end 291 drives the second driven end 26A3, thereby achieving the rotation of the upper locking link 26A. Understandably, when the transmission component 29 rotates clockwise or counterclockwise, the upper locking link 26A can also rotate clockwise or counterclockwise accordingly.
[0067] In one implementation method, please refer to Figure 1 The door lock device 100 also includes a mounting plate 31, a latch 21 and a locking arm 22 mounted on the mounting plate 31, a first rotating shaft 41 connected to the mounting plate 31, and the axis of the first rotating shaft 41 perpendicular to the mounting plate 31. The direction in which the key is inserted into the rotating arm 28 is perpendicular to the axis of the first rotating shaft 41.
[0068] Specifically, the mounting plate 31 is connected to the mounting housing 13 and encloses a receiving space, within which the latch 21 and locking arm 22 are housed. Both the first rotating shaft 41 and the third rotating shaft 43 are connected and fixed to the mounting housing 13 and the mounting plate 31. The mounting plate 31 is generally flat, allowing it to be perpendicular to the axis of the first rotating shaft 41. The rotating arm 28 should have a keyhole with teeth that mate with the key, the extension direction of which is the direction in which the key is inserted into the rotating arm 28. Since the axis of the first rotating shaft 41 is perpendicular to the mounting plate 31, the direction in which the key is inserted into the rotating arm 28 should be parallel to the surface of the mounting plate 31. Therefore, in the arrangement of the door lock device 100, the key and keyhole can be directly inserted, facilitating installation and a platform-based design.
[0069] In one implementation method, please refer to Figure 1 The door lock device 100 also includes a lock cylinder cover 32, which is sleeved on the outer periphery of the rotating arm 28 and connected to the rotating arm 28. The lock cylinder cover 32 can be used to guide the key insertion.
[0070] In one implementation method, please refer to Figure 3The inward-opening assembly includes an inward-opening rocker arm 33, which rotates around a fourth pivot 44. The rotation of the inward-opening rocker arm 33 connects to and drives a mating rocker arm 24 to rotate. Specifically, the inward-opening assembly also includes an inward-opening rocker 34, which rotates around a fifth pivot. The rotation of the inward-opening rocker 34 drives the inward-opening rocker arm 33 to rotate. The inward-opening rocker 34 can be directly or indirectly connected to the inner door handle. The axes of the fourth pivot 44 and the fifth pivot can be parallel, and the axes of the fourth pivot 44 and the first pivot 41 can intersect. The inward-opening rocker arm 33 rotates counterclockwise or clockwise to connect with the mating rocker arm 24, and then continues to rotate to drive the mating rocker arm 24 to rotate accordingly. The motion relationship of the mating rocker arm 24 after rotation can be referred to the above embodiment, and will not be repeated here.
[0071] In one implementation method, please refer to Figure 3 The inward-opening rocker arm 33 also includes a third flange 331. During the process of the push rod 25 switching from the first position to the second position, the inward-opening rocker arm 33 rotates so that the third flange 331 connects to the upper locking link 26A. The inward-opening rocker arm 33 drives the upper locking link 26A to rotate through the third flange 331. The rotation of the upper locking link 26A drives the push rod 25 to switch from the second position to the first position.
[0072] Specifically, the locking link 26A may include a third mating part 26A4, which can be used to connect with the third flange 331. When the drive member 27 indirectly drives the push rod 25 to the second position, the outward opening component cannot be unlocked by driving the mating rocker 23. When the user drives the inward opening rocker arm 33 to rotate for the first time, the inward opening rocker arm 33 also cannot be unlocked by driving the mating rocker arm 24. However, when the mating rocker arm 24 rotates, it can push the third mating part 26A4 through the third flange 331 to drive the locking link 26A. After the locking link 26A rotates, the push rod 25 can switch from the second position to the first position according to the movement relationship in the above embodiment. Then, the user can drive the inward opening rocker arm 33 to rotate again. Since the push rod 25 has returned to the first position, after the inward opening rocker arm 33 pushes the mating rocker arm 24, the push rod 25 can act on the locking arm 22 to unlock.
[0073] In one implementation method, please refer to Figures 8 to 10The door lock device 100 provided in this application can also be used as a child lock for a back door. Specifically, the inward opening assembly may further include an inward opening connecting arm 35, a rocker arm 36, and a switching element 37. The inward opening rocker arm 33, the inward opening connecting arm 35, and the rocker arm 36 are mounted on a fourth rotating shaft 44 and are all capable of rotating around the shaft. The inward opening connecting arm 35 has a third position and a fourth position in the radial direction of the fourth rotating shaft 44. In the third position, the inward opening connecting arm 35 drives the rocker arm 36 to rotate around the fourth rotating shaft 44, and the rocker arm 36 can rotate to contact the mating rocker arm 24 and drive the mating rocker arm 24 to rotate; in the fourth position, the rocker arm 36 and the inward opening connecting arm 35 are fixed relative to the fourth rotating shaft 44.
[0074] For details, please refer to Figure 8 The inwardly opening rocker arm 33, the swing arm 36, and the inwardly opening connecting arm 35 are stacked. The inwardly opening rocker arm 33 can also be connected to and driven by the inwardly opening rocker arm 34. The inwardly opening rocker arm 33 includes a third driving end 332 and a groove 333. The groove 333 is located between the third driving end 332 and the connection between the inwardly opening rocker arm 33 and the fourth rotating shaft 44. The groove 333 extends circumferentially around the fourth rotating shaft 44 and has an opening. The swing arm 36 has a receiving hole 361 that extends toward the fourth rotating shaft 44. The inwardly opening connecting arm 35 includes a third driven end 351, which can be cylindrical and can pass through the receiving hole 361. When the inwardly opening connecting arm 35 moves radially toward the fourth rotating shaft 44, the third driven end 351 can also move accordingly within the receiving hole 361.
[0075] Please refer to Figure 10 When the inward-opening connecting arm 35 is in the third position, the third driven end 351 can be located at the end of the receiving hole 361 away from the fourth rotating shaft 44. When the inward-opening rocker arm 33 rotates, the third driving end 332 can connect with the third driven end 351, thereby driving the inward-opening connecting arm 35 to rotate through the third driven end 351. Furthermore, due to the restriction of the third driven end 351 by the receiving hole 361, the inward-opening connecting arm 35 can drive the rocker arm 36 to rotate accordingly. The rocker arm 36 can rotate to contact the mating rocker arm 24 and drive the mating rocker arm 24 to rotate, thereby achieving unlocking.
[0076] Please refer to Figure 10 When the inward-opening connecting arm 35 is in the fourth position, the third driven end 351 can be located at the end of the receiving hole 361 near the fourth rotating shaft 44. When the inward-opening rocker arm 33 rotates, the third driven end 351 is received into the groove 333 through the opening, so the inward-opening rocker arm 36 is not driven. The rocker arm 36 and the inward-opening connecting arm 35 are fixed relative to the fourth rotating shaft 44.
[0077] Please refer to Figure 8 and Figure 9 The switching element 37 can be connected to the inner opening connecting arm 35 by a shaft hole, and the switching element 37 can be used to control the inner opening connecting arm 35 to switch between the third position and the fourth position.
[0078] By setting the switching element 37 and using it to switch the connecting arm between the third and fourth positions, the locking and unlocking of the inward-opening component can be achieved. The structure is simple and the operation is convenient. Furthermore, the inward-opening connecting arm 35, the swing arm 36, and the switching element 37 can be directly added to the door lock device 100 provided in the above embodiments without redesigning the parts positions. This makes the door lock device 100 provided in this application highly versatile. It can be installed on the front door of a vehicle as a regular door lock device 100, or on the rear door as a child lock, thereby reducing the design cost of the door lock device 100.
[0079] The complete movement process of the door lock device 100 is described in detail below.
[0080] Locking in the unlocked state: When the car door is gently closed, the latch moves into the locking groove, and as the car door gradually closes, the latch pushes the bolt 21 to rotate by connecting with the wall of the locking groove. The locking arm 22 maintains its rotational potential energy under the action of the return spring, and the locking arm 22 and the bolt 21 are engaged.
[0081] Unlocking the outward-opening component in the unlocked state: When a passenger pulls the outer door handle, the outward-opening component drives the cooperating rocker arm 23 to rotate. At this time, the cooperating rocker arm 23 drives the coaxial cooperating rocker arm 24 to rotate. The cooperating rocker arm 24 pushes the locking arm 22 to rotate through the push rod 25. The locking arm 22 rotates against the elastic force of the return spring, so that the latch 21 rotates under the action of the return spring, and the latch is disengaged to achieve the unlocking purpose.
[0082] Unlocking the inward-opening component in the unlocked state: When a passenger pulls the interior door handle, the inward-opening rocker arm 33 rotates, causing the inward-opening rocker arm 33 to push the cooperating rocker arm 24 to rotate, while the cooperating rocker arm 23 remains stationary. The cooperating rocker arm 24 then pushes the locking arm 22 to rotate via the push rod 25. The locking arm 22 rotates against the spring force of the return spring, causing the latch 21 to rotate under the action of the return spring, thus disengaging the latch and achieving the unlocking purpose.
[0083] Switching between locked and unlocked states: After the door is closed, the drive unit 27 drives the locking link 26 to pull the push rod 25 from the first position to the second position. In conjunction with the rocker arm 24 rotating the push rod 25, the push rod 25 cannot connect with the locking arm 22, thus preventing the locking arm 22 from being pushed. The locking arm 22 and the latch 21 remain stationary and locked, achieving the locking purpose. When the user switches to the unlocked state, the drive unit 27 drives the locking link 26 to pull the push rod 25 back from the second position to the first position. The door lock device 100 can then perform the unlocking process of the external opening component or the internal component as described above. Furthermore, switching between locked and unlocked states can also be achieved using a key. By inserting the key outside the vehicle and turning it, the rotating arm 28 rotates. The rotating arm 28, through the transmission unit 29, drives the locking link 26 to perform the above-mentioned movement, allowing the push rod 25 to switch between the first and second positions. Subsequent steps will not be elaborated further.
[0084] Double-pull unlocking of the inward-opening component: When the door lock device 100 is in the locked state, if a passenger inside the door needs to unlock it in an emergency, the passenger can pull the interior handle twice to unlock and open the door. Upon the first pull, the inward-opening rocker arm 33 pushes the upper locking link 26A to rotate, which in turn drives the lower locking link 26B to rotate, thereby causing the push rod 25 to return to the first position. When the interior handle is pulled again, unlocking is achieved through the aforementioned inward-opening component unlocking process.
[0085] Child lock locking and unlocking state switching: After the door is closed, the passenger can switch the inward opening connecting arm 35 to the fourth position via the control switch 37. When the inward opening rocker arm 33 rotates, the inward opening rocker arm 33 cannot drive the inward opening connecting arm 35 and the rocker arm 36 to rotate accordingly. That is, the inward opening connecting arm 35 and the rocker arm 36 are stationary relative to the inward opening rocker arm 33, thus cooperating with the rocker arm 24 to be undriven, thereby achieving the purpose of locking. Then, the passenger can switch the inward opening connecting arm 35 to the third position via the control switch 37. The inward opening connecting arm 35 and the rocker arm 36 can rotate under the drive of the inward opening rocker arm 33, thus cooperating with the rocker arm 24 to be driven, thereby achieving unlocking.
