Detailed Implementation
[0026] 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.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] The door lock device provided in this application can be used in vehicles, including gasoline-powered cars and new energy electric vehicles. Preferably, the vehicle can have an electric suction door with automatic locking, and the door lock device helps the vehicle to open and lock the door. Specifically, the door lock device can include an inner opening mechanism and an outer opening mechanism, which can be linked together. The inner opening mechanism 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 drives the inner opening mechanism to unlock and open the door. The outer casing mechanism 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 drives the outer opening mechanism to unlock and open the door.
[0031] In one implementation method, please refer to Figure 1 The door lock device 1000 includes a bolt 11, a latching assembly 20, and an outward-opening rocker arm 31. The bolt 11 rotates around a first pivot 51; the latching assembly 20 drives the bolt 11 to a fully locked state; the outward-opening rocker arm 31 rotates around a second pivot 52. During the process of the latching assembly 20 driving the bolt 11 to the fully locked state, the outward-opening rocker arm 31 connects to the latching assembly 20 and drives the latching assembly 20 to separate from the bolt 11, thereby allowing the bolt 11 to rotate to an unlocked state.
[0032] Specifically, the door lock device 1000 can be installed on the vehicle body or on the door. The door lock device 1000 is used in conjunction with a latch to close or lock the door. Please refer to [reference needed]. Figure 1 and Figure 2 The door lock device 1000 includes a housing 100 and a mounting plate 101. The latch 11 and the latching assembly 20 are both mounted within the housing 100, and at least a portion of the outward-opening rocker arm 31 is exposed outside the housing 100. A first rotating shaft 51 and a second rotating shaft 52 are both mounted on the mounting plate 101, and the axes of the first rotating shaft 51 and the second rotating shaft 52 are parallel. The latch 11 is disposed on the first rotating shaft 51 and is capable of rotating clockwise or counterclockwise about the first rotating shaft 51. The outward-opening rocker arm 31 is disposed on the second rotating shaft 52 and is capable of rotating clockwise or counterclockwise about the second rotating shaft 52. (Please refer to...) Figure 5 The latch 11 includes a locking groove 111, which forms from the edge of the latch 11 and extends toward the position of the first pivot 51. A sliding groove 102 is also provided on the mounting plate 101. Before the latch is inserted, the opening of the locking groove 111 can be in the same direction as the opening of the sliding groove 102. The latch can slide within the sliding groove 102 and simultaneously be accommodated in the locking groove 111. For example, when the car door is gently closed, the latch can move into the sliding groove 102 and the locking groove 111. As the car door gradually closes, the latch can push the latch 11 to gradually rotate by connecting with the wall of the locking groove 111 until the opening of the locking groove 111 is opposite to the opening of the sliding groove 102, at which point the latch 11 and the latch cooperate to achieve locking.
[0033] In one embodiment, the latch 11 may include an unlocked state, a half-locked state, and a fully locked state. In the unlocked state, the opening of the locking groove 111 can be in the same direction as the opening of the slide groove 102, and the latch can move out of the locking groove 111 and the slide groove 102. During the transition from the unlocked state to the half-locked state, the latch and the latch 11 can move in the manner described above. After the latch pushes the latch 11 to a stop, it is in the half-locked state, and in the half-locked state, the latch 11 can be restricted by the retaining member and remain in the half-locked state. During the transition from the half-locked state to the fully locked state, the latch 11 can continue to be driven to rotate in the same direction by the engaging component 20; until the latch can no longer push the latch 11 in the opposite direction and disengages, the fully locked state is achieved. It can be understood that in the half-locked state, the door lock device 1000 can be restored to the unlocked state by the inward opening mechanism or the outward opening mechanism described above. In the fully locked state, the door lock device 1000 can achieve full lock retention through electronic or mechanical control, meaning that the inner opening mechanism or the outer opening mechanism cannot unlock; the inner opening mechanism or the outer opening mechanism can only unlock when the full lock retention is canceled.
[0034] In one implementation method, please refer to Figure 1The latch 11 can be connected to a first return spring 41, which is mounted on a first rotating shaft 51. The latch 11 tends to rotate in a first rotation direction under the action of the first return spring 41. During the process of the engaging assembly 20 driving the latch 11 to the fully locked state, the engaging assembly 20 can at least partially move or rotate in the first direction, thereby driving the latch 11 to rotate in a second rotation direction. If the passenger needs to unlock and release the door, the outward-opening rocker arm 31 can rotate around the second rotating shaft 52 to connect with the engaging assembly 20, and continue to rotate until a portion of the engaging assembly 20 moves or rotates in the second direction, so that the engaging assembly 20 separates from the latch 11, and the latch 11 can rotate back to the unlocked state under the action of the first return spring 41. The outward-opening rocker arm 31 can be directly or indirectly connected to the aforementioned inward-opening mechanism or outward-opening mechanism. It is understood that the door lock device 1000 provided in this application can be used in an electric suction door, so the engaging assembly 20 is preferably an electrically controlled automatic assembly. After the user gently closes the car door, the door closes to the body, and the latch 11 can move to the fully locked state under the action of the latch and the closing assembly 20. However, if the passenger wants to unlock the door or the closing assembly 20 malfunctions during this process, the passenger can unlock and open the car door by actively driving the outward opening rocker arm 31.
[0035] In one implementation method, please refer to Figure 1 The outward-opening rocker arm 31 can be connected to a second return spring 42, which is mounted on the second rotating shaft 52. Under the action of the second return spring 42, the outward-opening rocker arm 31 tends to rotate in the second rotation direction. After the passenger cancels the drive of the inward-opening mechanism or the outward-opening mechanism, the outward-opening mechanism can rotate back under the action of the first return spring 41.
[0036] In one embodiment, after the engaging component 20 drives the bolt 11 to the fully locked state, and the engaging component 20 is in the process of resetting, if the engaging component 20 malfunctions and stops in its travel, the outward-opening rocker arm 31 can also drive the engaging component 20 back to the initial position, thereby preventing the engaging component 20 from blocking the bolt 11 from returning to the unlocked state while it is stopped in its travel.
[0037] This application drives the latch 11 to rotate via the engaging component 20, enabling the latch 11 to reach the fully locked state. Furthermore, an outward-opening rocker arm 31 is designed to connect to and drive the engaging component 20 to separate from the latch 11 during the engagement process, thereby interrupting the engaging process of the engaging component 20 and allowing the latch 11 to return to the unlocked state. This allows passengers to open the door, achieving the purpose of emergency unlocking.
[0038] In one implementation method, please refer to Figure 1 and Figure 4The suction assembly 20 includes a suction arm 21, which moves toward the latch 11 to connect with the latch 11. The suction arm 21 is used to drive the latch 11 to rotate to the fully locked state. During the process of the suction arm 21 driving the latch 11 to the fully locked state, the outward rocker arm 31 is connected to the suction arm 21 and drives the suction arm 21 to move away from the latch 11 so that the latch 11 rotates to the unlocked state.
[0039] Specifically, the suction arm 21 can be a long rod. The suction arm 21 can be connected to an electric device, which can drive the suction arm 21 to push the latch 11 to rotate tangentially along the outer periphery of the latch 11. Understandably, during the process of the suction arm 21 driving the latch 11 to rotate to the fully locked state, the suction arm 21 first moves towards the latch 11 until it connects with it; then the electric device continues to drive the suction arm 21, moving it until it pushes the latch 11 to rotate, and the rotation direction can be the second rotation direction mentioned above. When the passenger needs to open the door during this process, the outward opening rocker arm 31 can rotate to connect with the suction arm 21, and then continue to drive the outward opening rocker arm 31 to rotate to push the suction arm 21 away, causing the suction arm 21 to move away from the latch 11. After being no longer pushed by the suction arm 21, the latch 11 can rotate back under the action of the first return spring 41. In one embodiment, during the above process, the driving force of the electric device can be less than the driving force of the passenger, so that when the door is opened, the driving force applied by the passenger is greater than the driving force of the electric device, so that the suction arm 21 can move away from the latch 11.
[0040] In one implementation method, please refer to Figure 1 The engaging arm 21 can be connected to a third return spring 43. Under the action of the third return spring 43, the engaging arm 21 always tends to move away from the locking tongue 11. After the engaging assembly 20 drives the locking tongue 11 to the fully locked state, the locking tongue 11 can be held in this state by the action of the holding member. The engaging arm 21 can then be reset under the action of the third return spring 43 and wait for the next engaging and locking process.
[0041] In one implementation method, please refer to Figure 4 The suction arm 21 may include a first working surface 21A, through which it moves and connects to the latch 11. The first working surface 21A may be relatively rough to increase friction, which helps the suction arm 21 push the latch 11. The third return spring 43 and the aforementioned electric device may be connected to the end of the suction arm 21 away from the first working surface 21A, thereby enabling a longer reciprocating stroke for the suction, thus creating a lever effect and saving the required driving force.
[0042] In one implementation method, please refer to Figure 3 and Figure 4The outward-opening rocker arm 31 includes a first mating part 311, and the suction arm 21 includes a second mating part 211. The outward-opening rocker arm 31 rotates until the first mating part 311 and the second mating part 211 are connected. The outward-opening rocker arm 31 drives the second mating part 211 to engage through the first mating part 311, so that the suction arm 21 moves away from the locking tongue 11.
[0043] Specifically, along the axial direction of the second rotating shaft 52, the suction arm 21 can be located between the outward-opening rocker arm 31 and the mounting plate 101. The first mating part 311 can be a guide post protruding from the outward-opening rocker arm 31 toward the suction arm 21, and the first mating part 311 can be located near the outer periphery of the outward-opening rocker arm 31. When the outward-opening rocker arm 31 rotates, the first mating part 311 should perform a circular motion about the second rotating shaft 52. The second mating part 211 is a structure that protrudes from the suction arm 21 toward the outward-opening rocker arm 31. During the circular motion of the first mating part 311, the first mating part 311 can connect with the second mating part 211 and thereby drive the suction arm 21. Preferably, the second mating part 211 can be located on the side of the first mating part 311 facing away from the second rotating shaft 52, and the second mating part 211 should at least partially be bent toward the second rotating shaft 52. That is, on the circumference of the first mating part 311's movement, the curved portion of the second mating part 211 should extend beyond the aforementioned circumference and be closer to the second pivot 52. Understandably, the radius of the circumference formed by the circular movement of the first mating part 311 should be fixed. In order for the first mating part 311 to connect with the second mating part 211, and for the second mating part 211 to be able to be pushed, the position of the second mating part 211 should at least be located on the aforementioned circumference and should extend beyond the circumference to block the first mating part 311. In this way, the first mating part 311 can have sufficient pushing stroke during movement, allowing the engaging arm 21 to move away from the locking tongue 11 after being pushed.
[0044] In one implementation method, please refer to Figure 1 and Figure 3 The suction assembly 20 also includes a drive member 22 and a suction rocker arm 23. The drive member 22 is connected to the suction rocker arm 23, and the suction rocker arm 23 is connected to the suction arm 21. The drive member 22 drives the suction rocker arm 23 to rotate around the third rotating shaft 53, and the suction rocker arm 23 drives the suction arm 21 to move so that the locking tongue 11 rotates to the fully locked state.
[0045] Specifically, the driving component 22 can be the electric device in the above embodiment, specifically a motor. Please refer to... Figure 1 and Figure 3The attraction assembly 20 also includes an attraction pull line 24 and an attraction pivot 25. One end of the attraction pull line 24 has a fixed shaft 241, and the attraction rocker arm 23 is connected to the fixed shaft 241. The end of the attraction rocker arm 23 away from the fixed shaft 241 is rotatably connected to the attraction arm 21 via the attraction pivot 25, and a third return spring 43 can also be installed on the attraction pivot 25. The hole of the third pivot 53 is located between the hole of the fixed shaft 241 and the hole of the attraction pivot 25. When the attraction pull line 24 is pulled, the end of the attraction rocker arm 23 connected to the fixed shaft 241 descends, and the end connected to the attraction pivot 25 rises. This can form a balance-like structure, thereby driving the attraction arm 21 to move with the attraction rocker arm 23.
[0046] In one implementation method, please refer to Figure 1 The engaging rocker arm 23 can be connected to a fourth return spring 44, which is mounted on the third rotating shaft 53. Under the action of the fourth return spring 44, the engaging rocker arm 23 always tends to pull the engaging arm 21 back. After the engaging assembly 20 drives the locking tongue 11 to the fully locked state, the locking tongue 11 can be held in this state by the action of the holding member. The engaging rocker arm 23 can then be reset under the action of the fourth return spring 44 and wait for the next engaging and locking process.
[0047] In one implementation method, please refer to Figure 1 and Figure 3 The door lock device 1000 also includes a stabilizing shaft 63 and a first connecting plate 61. The stabilizing shaft 63 is mounted on the mounting plate 101, and its axis is parallel to the third rotating shaft 53. The opposite ends of the first connecting plate 61 are connected to the stabilizing shaft 63 and the third rotating shaft 53, respectively, and the engaging rocker arm 23 can be located between the mounting plate 101 and the first connecting plate 61. The first connecting plate 61 is used to reinforce the engaging rocker arm 23.
[0048] In one implementation method, please refer to Figure 1 and Figure 5 The door lock device 1000 also includes a locking arm 12, which rotates around a second pivot 52. The bolt 11 also includes a half-lock state. The locking arm 12 is used to connect the bolt 11 to maintain the half-lock state. The engaging assembly 20 drives the bolt 11 from the half-lock state to the fully locked state.
[0049] Specifically, the locking arm 12 can be the aforementioned latching member. The locking arm 12 is mounted on the second rotating shaft 52 and can rotate clockwise or counterclockwise around the second rotating shaft 52. The locking arm 12 can be located between the mounting plate 101 and the outward-opening rocker arm 31. After the latch slides into the locking groove 111 and the sliding groove 102, the bolt 11 rotates to a half-locked state, and the locking arm 12 can connect with the bolt 11 to hold the bolt 11, thus keeping the bolt 11 in a half-locked state. Then, driven by the engaging assembly 20, the bolt 11 can continue to reach a fully locked state, and in the fully locked state, the locking arm 12 can still hold the bolt 11, so that the bolt 11 rotates to maintain the fully locked state.
[0050] In one embodiment, the locking arm 12 can also be directly or indirectly connected to the outward-opening rocker arm 31. Specifically, in the half-locked state, the passenger can drive the outward-opening rocker arm 31 to rotate via the outward-opening mechanism or the inward-opening mechanism. At least a portion of the outward-opening rocker arm 31 can rotate to connect with the locking arm 12, and upon further rotation, it pushes the locking arm 12 to rotate, thereby separating the locking arm 12 from the latch 11. The latch 11 can rotate to a position where the latch can be moved out under the action of the first return spring 41, thereby unlocking. Of course, when switching from the half-locked state to the fully locked state, for emergency unlocking, the outward-opening rocker arm 31 can simultaneously drive the engaging arm 21 and the locking arm 12 to move, thereby unlocking.
[0051] In one implementation method, please refer to Figure 1 The locking arm 12 can be connected to a fifth return spring 45, which is mounted on the second rotating shaft 52. Under the action of the fifth return spring 45, the locking arm 12 always tends to rotate in the second rotation direction. When the latch 11 is in a half-locked or fully locked state, the locking arm 12 can hold the latch 11 under the action of the fifth return spring 45. Alternatively, after the outward-opening rocker arm 31 pushes the locking arm 12 open, the locking arm 12 can return to its original position and wait for the next locking process.
[0052] In one implementation method, please refer to Figures 5 to 7 The locking tongue 11 includes a first connecting portion 112 and a second connecting portion 113, and the locking arm 12 includes a third connecting portion 122. In the half-locked state, the first connecting portion 112 and the third connecting portion 122 are connected; in the fully locked state, the second connecting portion 113 and the third connecting portion 122 are connected. Specifically, the first connecting portion 112 can be a notch formed by recessing inward from the outer periphery of the locking tongue 11, and the second connecting portion 113 can be the wall surface of the locking groove 111 closest to the outer periphery. The third connecting portion 122 can be a stepped notch formed on the locking arm 12. In the half-locked state, the locking arm 12 can hold the locking tongue 11 through the connection between the first connecting portion 112 and the third connecting portion 122; in the fully locked state, the locking arm 12 can hold the locking tongue 11 through the connection between the second connecting portion 113 and the third connecting portion 122.
[0053] The specific locking mechanism can be as follows: After the latch moves into the slide groove 102 and the locking groove 111, it pushes the latch 11 to rotate counterclockwise. Simultaneously, the first return spring 41 provides a clockwise tendency for the latch 11. The fifth return spring 45 provides a counterclockwise tendency for the locking arm 12. In the clockwise direction, the second connecting part 113 is located behind the first connecting part 112. Therefore, when the latch pushes the latch 11 to the half-locked state, the first connecting part 112 first connects to the third connecting part 122, and the outer peripheral wall of the latch 11 contacts the outer peripheral wall of the locking arm 12. Then, driven by the engaging assembly 20, the latch 11 continues to rotate counterclockwise until the second connecting part 113 connects to the third connecting part 122. If unlocking is required while the device is in a partially locked or fully locked state, simply drive the outward-opening rocker arm 31 to push the locking arm 12 away from the third connecting part 122, causing the locking arm 12 to rotate clockwise, thus separating the locking arm 12 from the bolt 11. The bolt 11 can then be reset, and the locking arm 12 can also be reset accordingly after the power to the outward-opening rocker arm 31 is removed.
[0054] In one implementation method, please refer to Figure 1 , Figure 3 and Figure 5 The door lock device 1000 also includes a push rod 32, which is connected to an outward-opening rocker arm 31. During the process of the engaging assembly 20 driving the bolt 11 to the fully locked state, the outward-opening rocker arm drives the push rod 32 to rotate. The push rod 32 is connected to and drives the locking arm 12 to rotate, thereby separating the locking arm 12 from the bolt 11. Specifically, one end of the push rod 32 is rotatably connected to the housing 100, and the opposite end is connected to the outward-opening rocker arm 31. When the outward-opening rocker arm 31 rotates, it can correspondingly drive the push rod 32 to rotate around its connection point with the housing 100.
[0055] In one implementation method, please refer to Figure 1 and Figure 3 The door lock device 1000 also includes a pull rod 33, and the outward-opening rocker arm 31 includes a flange 314. The pull rod 33 is connected to one end of the outward-opening rocker arm 31 and can rotate the outward-opening rocker arm 31 by pushing or pulling. The flange 314 is located at the end of the outward-opening rocker arm 31 opposite to the pull rod 33. The inward-opening mechanism can drive the outward-opening rocker arm 31 to rotate through the flange 314.
[0056] In one implementation method, please refer to Figure 3 and Figure 5 The push rod 32 includes a third mating part 321, and the locking arm 12 includes a fourth mating part 121. The push rod 32 drives the third mating part 321 to rotate so that the third mating part 321 and the fourth mating part 121 are connected. The outward-opening rocker arm 31 drives the fourth mating part 121 to engage through the third mating part 321 so that the locking arm 12 and the locking tongue 11 are separated.
[0057] Specifically, the third mating part 321 is located at the end of the push rod 32 away from the connection with the housing 100 and extends towards the mounting plate 101. The fourth mating part 121 is located at the end of the locking arm 12 away from the third connecting part 122, and the fourth mating part 121 can extend away from the mounting plate 101. The second rotating shaft 52 is located between the fourth mating part 121 and the third connecting part 122. The outward-opening rocker arm 31 can drive the third mating part 321 to move circumferentially, so that when the fourth mating part 121 is located on the movement path of the third mating part 321, the third mating part 321 can push the fourth mating part 121 to make the locking arm 12 form a lever movement. Furthermore, the third mating part 321 and the fourth mating part 121 can each have smooth contact surfaces. After the push rod 32 rotates to the point where the third mating part 321 contacts the fourth mating part 121, their contact surfaces can be connected in parallel. After the push rod 32 continues to rotate, it can drive the locking arm 12 to rotate.
[0058] In one implementation method, please refer to Figure 3 and Figure 4 The outward-opening rocker arm 31 also has a receiving groove 312, and the third mating part 321 is accommodated in the receiving groove 312. The outward-opening rocker arm 31 drives the third mating part 321 to move through the wall of the receiving groove 312. Specifically, the receiving groove 312 is formed on the edge of the outward-opening rocker arm 31 and extends toward the direction of the second rotating shaft 52 to form a "U"-shaped groove. The third mating part 321 is accommodated in the receiving groove 312 and extends through the receiving groove 312 to the plane where the locking arm 12 is located. After the outward-opening rocker arm 31 rotates, the wall of the receiving groove 312 can push the third mating part 321 to drive the push rod 32 to rotate together, and after the third mating part 321 rotates to contact the fourth mating part 121, it pushes the locking arm 12.
[0059] In one implementation method, please refer to Figure 4 The outward-opening rocker arm 31 may include a fifth mating portion 313, which is connected to the wall of the receiving groove 312 and can be connected to a third mating portion 321 to push the third mating portion 321. Preferably, the fifth mating portion 313 may be formed by bending a portion of the outward-opening rocker arm 31 downward, which increases the contact area between the outward-opening rocker arm 31 and the third mating portion 321, thereby enabling more stable power transmission.
[0060] In one embodiment, the door lock device 1000 further includes a second connecting plate 62, with its two ends, which are far apart, connected to a first rotating shaft 51 and a second rotating shaft 52, respectively. The second connecting plate 62 is used to fix the latch 11, the locking arm 12, and the outward-opening rocker arm 31 as described above.
[0061] The complete movement process of the door lock device 1000 is described in detail below.
[0062] Magnetic locking: Please refer to Figure 6 and Figure 7 As the car door is gently closed, the latch moves into the slide groove 102 and the locking groove 111. As the door gradually closes, the latch, through its connection with the wall of the locking groove 111, pushes the bolt 11 to rotate until the opening of the locking groove 111 is separated from the opening of the slide groove 102. At this time, the locking arm 12 holds the bolt 11 in a half-locked state. Then, a full-lock signal is triggered, and the drive unit 22 drives the suction arm 21 through the suction cable 24 and the suction rocker arm 23 to push the bolt 11 to continue rotating. The locking arm 12 connects to the second connecting part 113, so that the bolt 11 is in a fully locked state.
[0063] Emergency unlocking: During the transition from the half-locked to the fully locked state, the inner or outer opening mechanism drives the outer opening rocker arm 31 to rotate, causing the push rod 32 to rotate accordingly. After the outer opening rocker arm 31 rotates and connects with the engaging arm 21, it drives the engaging arm 21 to retract away from the latch 11. After the push rod 32 rotates and connects with the locking arm 12, it drives the locking arm 12 to rotate, thereby separating the third connecting part 122 from the second connecting part 113. Under the action of the first return spring 41, the latch 11 returns to the position where the opening of the locking groove 111 is in the same direction as the opening of the slide groove 102, allowing the latch to be removed.
