[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a two-way unlocking mechanism, including a first handle, a first pin, and a linkage assembly. The first handle is installed on the inside of a sliding door. The linkage assembly includes a first link, a second link, a third link, and a fourth link, which are coaxially hinged. The first link triggers the lock assembly and has a first groove. The second link has a second groove A and a second groove B, which are interconnected. When the first pin is inserted into the first and second grooves A, the second link can move relative to the first link. When the first pin is inserted into the first and second grooves B, the second link and the first link are relatively stationary. The first handle is connected to the third link via a first pull rod, which drives the second link to rotate. The first handle is also connected to the fourth link via the second pull rod, which pushes the first pin into the second groove A.

[0022] When in use, the two-way unlocking mechanism includes an unlockable state, an unlockable state, and an unlocked state.

[0023] When in the unlockable state, the first link is in the first initial position, the second link is in the second initial position, the third link is in the third initial position, and the fourth link is in the fourth end position. At this time, the first pin is located at the junction of the second slide groove A and the second slide groove B. The first handle is in the first stationary position.

[0024] When the first handle is moved from the first stationary position to the first unlocked position, the first handle drives the third link to rotate from the third initial position to the third end position via the first pull rod. The third link, through the second pin, drives the second link to rotate from the second initial position to the second end position. Since the first pin is located in the second slide groove A, the first link remains in its first initial position. The first handle pulls the fourth link via the second pull rod, causing the fourth link to move from the fourth end position to the fourth initial position, releasing the fourth link from its limiting position on the first pin. When the first handle returns to the first stationary position, the second link returns to the second initial position. At this time, since the first pin is no longer limited by the fourth link, it can insert into the first slide groove and the second slide groove B; the third link returns to the third initial position; and the fourth link is located in the fourth initial position. At this point, the bidirectional unlocking mechanism is considered to be in the unlockable state.

[0025] When the first handle moves from the first stationary position to the first unlocked position again, the first handle is linked in sequence through the first pull rod, the third link, and the second link, driving the first link to move from the first initial position to the first end position, triggering the lock assembly, and completing the unlocking. At this time, it is recorded that the two-way unlocking mechanism is in the unlocked state.

[0026] With this design, users can unlock and unlock the door by operating the first handle on both sides, simplifying the door opening process and reducing the number of buttons on the door. Attached Figure Description

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] like Figures 1 to 10 As shown, this utility model provides a two-way unlocking mechanism, including a first handle 100, a first pin 210, and a linkage assembly. The first handle 100 is installed on the inner side of a sliding door; the linkage assembly includes a first link 310, a second link 320, a third link 330, and a fourth link 340. The first link 310, second link 320, and third link 330 are coaxially hinged. The first link 310 is used to trigger the lock assembly. The first link 310 has a first groove, and the second link 320 has a second groove A and a second groove B. The second groove A and the second groove B are interconnected. When the first pin 210 is inserted into the first groove or the second groove... When in slot A, the second link 320 and the first link 310 can move relative to each other. When the first pin 210 is inserted into the first slide groove and the second slide groove B, the second link 320 and the first link 310 are relatively stationary. The first handle 100 is connected to the third link 330 through the first pull rod 410. The third link 330 can drive the second link 320 to rotate. The first handle 100 is connected to the fourth link 340 through the second pull rod 420. The fourth link 340 can push the first pin 210 into the second slide groove A.

[0050] For example, the first link 310, the second link 320 and the third link 330 are hinged to the sliding door via the first hinge shaft 610, and the fourth link 340 is hinged to the sliding door via the second hinge shaft 620. The axis of the first hinge shaft 610 is parallel to the axis of the second hinge shaft 620.

[0051] For example, one end of the first link 310 is used to trigger the lock assembly. That is, this end of the first link 310 includes a first initial position and a first end position relative to the sliding door. The first link 310 switches between the first initial position and the first end position by rotating with the sliding door. When the first link 310 rotates from the first initial position to the first end position, the first link 310 triggers the lock assembly to unlock. The other end of the first link 310 is provided with a first groove. The length direction of the first groove is parallel to the radial direction of the first hinge shaft 610, and the depth direction of the first groove is parallel to the axial direction of the first hinge shaft 610.

[0052] For example, the second link 320 has a second initial position and a second final position relative to the sliding door. The second link 320 switches between the second initial position and the second final position by rotating with the sliding door. One end of the second link 320 is provided with a second slide groove A and a second slide groove B. The second slide groove A is opened around the axis of the first hinge shaft 610 and is arc-shaped. The length direction of the second slide groove B is parallel to the radial direction of the first hinge shaft 610. The depth directions of the second slide groove A and the second slide groove B are both parallel to the axial direction of the first hinge shaft 610. The second slide groove A and the second slide groove B are connected.

[0053] The first link 310 and the second link 320 are connected by a first pin 210. One end of the first pin 210 is inserted into the first groove and can slide relative to the first link 310 along the length of the first groove. The other end of the first pin 210 is inserted into the second groove A or the second groove B. When the first pin 210 is inserted into the second groove A, the first pin 210 can move relative to the second link 320 along the length of the second groove A. That is, at this time, the second link 320 rotates around the first hinge axis 610. When it moves from the second initial position to the second end position, it cannot drive the first link 310 through the first pin 210. That is, the first link 310 is always in the first initial position. When the first pin 210 is inserted into the second slide groove B, the first pin 210 can slide relative to the second link 320 along the length direction of the second slide groove B. The first pin 210, the first link 310, and the second link 320 do not have the degree of freedom to rotate around the first hinge axis 610. Therefore, when the second link 320 rotates from the second initial position to the second end position, the second link 320 can drive the first link 310 through the first pin 210, so that the first link 310 rotates from the first initial position to the first end position, thus completing the unlocking action.

[0054] It should be noted that when the first pin 210 is located at the junction of the second slide groove A and the second slide groove B, it is considered that the first pin 210 is located in the second slide groove A. That is, when the first pin 210 is located in this position, the second connecting rod 320 cannot drive the first connecting rod 310 to rotate through the first pin 210.

[0055] For example, the third link 330 has a third initial position and a third final position relative to the sliding door. The third link 330 switches between the third initial position and the third final position by rotating with the sliding door. The third link 330 is connected to the second link 320. When the third link 330 rotates from the third initial position to the third final position, the third link 330 can drive the second link 320, so that the second link 320 can rotate from the second initial position to the second final position.

[0056] For example, the fourth link 340 has a fourth initial position and a fourth final position relative to the sliding door. The fourth link 340 switches between the fourth initial position and the fourth final position by rotating with the sliding door. The fourth link 340 abuts against the first pin 210. When the fourth link 340 moves from the fourth initial position to the fourth final position, the fourth link 340 can drive the first pin 210 to move relative to the second link 320 along the length direction of the second slide groove B until it moves to the junction of the second slide groove B and the second slide groove A. That is, when the fourth link 340 is in the fourth final position, the first pin 210 is always located in the second slide groove A.

[0057] For example, a first handle 100 is movably mounted on a sliding door. The first handle 100 includes a first stationary position and a first unlocked position relative to the sliding door. The first handle 100 is connected to a third link 330 via a first link 310 and to a fourth link 340 via a second link 320. When the first handle 100 moves from the first stationary position to the first unlocked position, it can drive the third link 330 to move from the third initial position to the third end position via the first pull rod 410, and it can drive the fourth link 340 to move from the fourth initial position to the fourth end position via the second pull rod 420.

[0058] It should be noted that the first handle 100 is installed on the inside of the sliding door, which can be understood as the first handle 100 being installed inside the carriage.

[0059] When in use, the two-way unlocking mechanism includes an unlockable state, an unlockable state, and an unlocked state.

[0060] When in the unlockable state, the first link 310 is in the first initial position, the second link 320 is in the second initial position, the third link 330 is in the third initial position, and the fourth link 340 is in the fourth end position. At this time, the first pin 210 is located at the junction of the second slide A and the second slide B. The first handle 100 is in the first stationary position.

[0061] When the first handle 100 is moved from the first stationary position to the first unlocked position, the first handle 100 can drive the third link 330 to rotate from the third initial position to the third end position via the first pull rod 410. The third link 330 can drive the second link 320 to rotate from the second initial position to the second end position via the second pin 220. Since the first pin 210 is located in the second slide groove A, the first link 310 is always located in its first initial position. The first handle 100 pulls the fourth link 340 via the second pull rod 420, causing the fourth link 340 to move from the fourth end position to the fourth initial position, and the fourth link 340 releases the limit on the first pin 210. When the first handle 100 returns to the first stationary position, the second link 320 returns to the second initial position. At this time, the first pin 210 can be inserted into the first slide groove and the second slide groove B because it is no longer limited by the fourth link 340. The third link 330 returns to the third initial position, and the fourth link 340 is in the fourth initial position. At this time, it is recorded that the two-way unlocking mechanism is in the unlockable state.

[0062] When the first handle 100 moves from the first stationary position to the first unlocked position again, the first handle 100 is driven by the first pull rod 410, the third link 330 and the second link 320 in sequence, driving the first link 310 to move from the first initial position to the first end position, triggering the lock assembly and completing the unlocking. At this time, it is recorded that the two-way unlocking mechanism is in the unlocked state.

[0063] With this setup, users can unlock the door by operating the first handles 100 on both sides, simplifying the door opening process and reducing the number of buttons on the door.

[0064] Optionally, the second link 320 is further provided with a second slide groove C, in which a second pin 220 is slidably inserted, and the third link 330 drives the second link 320 through the second pin 220.

[0065] For example, the length direction of the second slide groove C is parallel to the radial direction of the first hinge shaft 610, and the depth direction of the second slide groove C is parallel to the axial direction of the first hinge shaft 610. One end of the second pin 220 is inserted into the second slide groove C, while the other end is exposed outside the second slide groove C. The second pin 220 can slide relative to the second connecting rod 320 along the length direction of the second slide groove C, and the third connecting rod 330 can abut against the end of the second pin 220 exposed outside the second slide groove C. In use, when the first handle 100 pulls the third connecting rod 330 to the third end position via the first pull rod 410, the third connecting rod 330 can abut against the second pin 220 to drive the second connecting rod 320 to rotate to the second end position.

[0066] For example, the second slide A and the second slide B are located on the same side of the first hinge shaft 610, and the second slide C is located on the other side of the first hinge shaft 610.

[0067] Optionally, the two-way unlocking mechanism also includes a second handle and a fifth link 350. The second handle is installed on the outside of the sliding door and can drive the first link 310 to rotate via the fifth link 350.

[0068] For example, the fifth link 350 is hinged to the sliding door via the first hinge shaft 610. The fifth link 350 has a fifth initial position and a fifth final position relative to the sliding door. The fifth link 350 switches between the fifth initial position and the fifth final position by rotating relative to the sliding door.

[0069] In one embodiment, a second handle is movably mounted on the outside of the sliding door, allowing the user to operate it from outside the vehicle. The second handle is connected to a fifth link 350 via a pull cable. The second handle has a second stationary position and a second unlocked position relative to the sliding door. When the second handle moves from the second stationary position to the second unlocked position, it drives the fifth link 350 to move from a fifth initial position to a fifth final position via a pull cable. The fifth link 350 is connected to a second link 320. When the fifth link 350 rotates from the fifth initial position to the fifth final position, the second link 320 rotates simultaneously from the second initial position to the second final position. If the door is already in an unlockable state, i.e., when the first pin 210 is inserted into the first and second slide grooves B, the door can be unlocked and opened through the coordinated action of the second handle, the fifth link 350, the second link 320, and the first link 310. If the device is in an unlockable state, that is, when the first pin 210 is inserted into the first slide groove and the second slide groove A, the second handle cannot drive the first link 310, and therefore cannot be unlocked.

[0070] In another embodiment, the second handle is movably installed on the outside of the sliding door, meaning the user can operate the second handle from outside the vehicle. The second handle is connected to the fifth link 350 via a pull cable. The second handle has a second stationary position and a second unlocked position relative to the sliding door. When the second handle moves from the second stationary position to the second unlocked position, the second handle can drive the fifth link 350 to move from the fifth initial position to the fifth end position via the pull cable. The fifth link 350 can abut against the first pin 210. The first pin 210 acts on the first link 310, thereby driving the first link 310 to rotate. That is, when the first pin 210 is inserted into the first slide groove and the second slide groove B, the fifth link 350 can abut against the first pin 210. When the fifth link 350 moves from the fifth initial position to the fifth end position, it can move from the first initial position to the first end position via the first pin 210 abutting against the first link 310, thus unlocking the door.

[0071] Optionally, the bidirectional unlocking mechanism also includes an actuator 500, the output end of which is provided with a gear, and the fourth link 340 is provided with a continuous protrusion, the gear meshing with the fourth link 340 for transmission. Thus, when the actuator 500 is activated, the gear rotates, driving the fourth link 340 to rotate relative to the sliding door, causing the fourth link 340 to move from the fourth initial position to the fourth end position.

[0072] Optionally, the two-way unlocking mechanism also includes a first elastic element, which makes the first pin 210 always tend to slide into the second groove B.

[0073] For example, the first elastic member includes a first winding portion and a first abutting portion. The first winding portion is connected to the first abutting portion. The first elastic member is made of elastic material and is capable of elastic deformation. The first winding portion is sleeved on the fifth link 350, and the first abutting portion abuts against the side of the first pin 210 facing away from the second slide groove B. When the fourth link 340 is at the fourth end position, the first pin 210 is in the second slide groove A, and the first elastic member undergoes elastic deformation. When the fourth link 340 returns to the fourth initial position, and the second link 320 returns to the second initial position, since the limiting of the fourth link 340 is missing, the first elastic member can recover its deformation, and the first elastic member drives the first pin 210 into the second slide groove B.

[0074] Optionally, the bidirectional unlocking mechanism further includes a second elastic element and a third elastic element, wherein the second elastic element is used to drive the second link 320 to reset, and the third elastic element is used to drive the third link 330 to reset.

[0075] In this embodiment, both the second and third elastic elements are torsion springs, both mounted on the first hinge shaft 610. When the first handle 100 moves from the first stationary position to the first unlocked position, the second link 320 moves from the second initial position to the second unlocked position, and the second elastic element undergoes elastic deformation. The third link 330 moves from the third initial position to the third unlocked position, and the third elastic element undergoes elastic deformation. When the first handle 100 returns to the first stationary position, the second elastic element recovers its deformation, causing the second link 320 to return from the second end position to the second initial position, and the third elastic element recovers its deformation, causing the third link 330 to return from the third end position to the third initial position.

[0076] Optionally, the two-way unlocking mechanism also includes a fourth elastic element, which is used to drive the first handle 100 to reset.

[0077] For example, when a user pulls the first handle 100 to move it from the first stationary position to the first unlocked position, the fourth elastic element undergoes elastic deformation. When the user removes the force, the fourth elastic element restores its deformation, causing the first handle 100 to return from the first unlocked position to the first stationary position.

[0078] Optionally, the second pull rod 420 is provided with a fourth slide groove, and the first handle 100 is slidably inserted into the fourth slide groove. The length direction of the fourth slide groove is parallel to the relative movement direction of the first handle 100 and the sliding door.

[0079] For example, the travel distance of the first handle 100 from the first stationary position to the first unlocked position is divided into a first process and a second process. In the first process, the first handle 100 drives the third link 330 and the second link 320 to rotate via the first pull rod 410. Since the first link 310 is in its first initial position, the movement of the second link 320 towards the second end position causes the first pin 210 to move from the junction of the second slide groove A and the second slide groove B into the second slide groove A, where it is supported by the side wall of the second slide groove A. The first handle 100 slides within the fourth slide groove and cannot act on the second pull rod 420. In the second process, the first handle 100 continues to drive the third link 330 and the second link 320 via the first pull rod 410. The first handle 100 then abuts against the side wall of the fourth slide groove, driving the second pull rod 420 and the fourth link 340, causing the fourth link 340 to move from the fourth end position to the fourth initial position. Since the first pin 210 is located in the second slide groove A at this time, the first pin 210 will not suddenly slide into the second slide groove B due to the movement of the fourth link 340, causing the first link 310 and the second link 320 to lock. The two-way unlocking mechanism will then skip the unlockable state from the unlockable state and directly enter the unlocked state.

[0080] A door assembly is also provided, including a sliding door, a lock assembly, and the aforementioned two-way unlocking mechanism. The lock assembly is installed on the sliding door for locking the sliding door to the vehicle frame, and the two-way unlocking mechanism is installed on the sliding door for triggering the lock assembly to release the locking between the sliding door and the vehicle frame.

[0081] Optionally, the lock assembly includes a first lock and a second lock. The first lock is installed on the front side of the sliding door and connected to the first link 310 via a pull rope. The second lock is installed on the rear side of the sliding door and connected to the first link 310 via a pull rope. Both the first lock and the second lock can lock the sliding door to the vehicle frame.

[0082] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
