Detailed implementation manners

[0017] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] Refer to Figure 1 and Figure 2 As shown, the present invention provides an inboard opening device for a vehicle sliding door, including a bottom plate 1, an inboard opening handle 2, a first lever 3, a first swing arm 4, a first rocker arm 5, and a main lock pull rod 6, wherein: The inboard opening handle 2 can move along the first direction D1, and the first direction D1 is the direction in which the inboard opening handle 2 moves clockwise.

[0019] The first lever 3 is arranged on the bottom plate 1. The first lever 3 is connected to the inside-opening handle 2. The first lever 3 can move in the same direction as the inside-opening handle 2. When the inside-opening handle 2 moves along the first direction D1, the first lever 3 moves synchronously along the first direction D1.

[0020] The first swing arm 4 is arranged between the bottom plate 1 and the first lever 3. The first swing arm 4 is connected to the first lever 3. The first swing arm 4 can move in the same direction as the first lever 3. Thus, when the inside-opening handle 2 moves along the first direction D1, under the action of the first lever 3, the first swing arm 4 also moves synchronously along the first direction D1.

[0021] The first rocker arm 5 is arranged on the bottom plate 1. The first rocker arm 5 can move along the second direction D2. The second direction D2 is the direction in which the first rocker arm 5 moves counterclockwise, that is, the second direction D2 is the opposite direction of the first direction D1. One end of the first rocker arm 5 is connected to the first swing arm 4.

[0022] One end of the main lock pull rod 6 is connected to the other end of the first rocker arm 5. The other end of the main lock pull rod 6 is connected to a main lock. When the first rocker arm 5 moves along the second direction D2, it can drive the main lock pull rod 6 to move, thereby unlocking the main lock.

[0023] Refer to Figure 3 As shown, when the inside-opening handle 2 is subjected to an external force and rotates clockwise (i.e., the first direction D1), it drives the first lever 3 to rotate clockwise. Further, the first swing arm 4 rotates clockwise synchronously. Under the drive of the first swing arm 4, the first rocker arm 5 rotates counterclockwise (i.e., the second direction D2). The main lock pull rod 6 moves under the action of the first rocker arm 5, thereby unlocking the main lock.

[0024] The conversion mechanism of the inside-opening device of the vehicle sliding door of the present invention is only composed of the first lever 3, the first swing arm 4, the first rocker arm 5 and the main lock pull rod 6. The unlocking of the main lock can be realized only by three steps of lever linkage, reducing the steps of lever linkage. The unlocking process is fast and convenient. The structure of the inside-opening device of the vehicle sliding door is simple, reducing the number of required components, which is beneficial to the lightweight design of the vehicle and the reduction of manufacturing costs.

[0025] In the embodiments provided by the present application, the inside-opening device of the vehicle sliding door includes a first pin shaft 7 and a second pin shaft 8. Both the first pin shaft 7 and the second pin shaft 8 are arranged on the bottom plate 1. The first lever 3 and the first swing arm 4 are sleeved on the first pin shaft 7, so that the first lever 3 and the first swing arm 4 can rotate around the first pin shaft 7. Further, when unlocking the main lock, the first lever 3 and the first swing arm 4 can rotate stably, ensuring the stability of unlocking the main lock.

[0026] The first swing arm 4 and the first rocker arm 5 are riveted through the second pin shaft 8. When the first swing arm 4 rotates, under the action of the second pin shaft 8, the first rocker arm 5 is driven to rotate around the second pin shaft 8, so that the first rocker arm 5 can rotate stably along the second direction D2, and the unlocking of the main lock is successfully realized.

[0027] After the main lock is unlocked, when the external force applied to the inner opening handle 2 disappears, the main lock should be able to reset, so as to ensure the safety of the vehicle. In a feasible embodiment, a first elastic restoring member 9 is further provided on the first pin shaft 7. One end of the first elastic restoring member 9 is connected to the first lever 3, and the other end of the first elastic restoring member 9 is connected to the bottom plate 1. During the movement of the first lever 3 along the first direction D1, the first elastic restoring member 9 is subjected to the acting force of the first lever 3 and undergoes elastic deformation to accumulate elastic acting force. When the main lock is unlocked and the acting force applied to the inner opening handle 2 disappears, the first elastic restoring member 9 applies the accumulated elastic acting force to the first lever 3, causing the first lever 3 to move in the opposite direction of the first direction D1, and the first swing arm 4 synchronously moves in the opposite direction of the first direction D1, thereby driving the first rocker arm 5 to move in the opposite direction of the second direction D2, so that the main lock is reset.

[0028] Preferably, the first elastic restoring member 9 is a torsion spring. The torsion spring is sleeved on the first pin shaft 7. A column 31 is provided on the first swing arm 4, and a vertical plate 11 is provided on the bottom plate 1. One end of the torsion spring abuts against the column 31, and the other end of the torsion spring abuts against the vertical plate 11. When the first swing arm 4 rotates along the first direction D1, the torsion spring undergoes elastic deformation to accumulate elastic acting force. When the external force applied to the inner opening handle 2 disappears, the torsion spring applies the elastic acting force to the first swing arm 4 to drive the first swing arm 4 to move in the opposite direction of the first direction D1, thereby realizing the reset of the main lock.

[0029] When the vehicle faces strong winds or impacts, it is easy to cause the door opening mechanism to start and open the door, which may cause accidents. To improve the reliability and safety of the door, a limit lock is provided inside the vehicle. The limit lock can provide support for the door to prevent accidental unlocking of the main lock, thereby reducing the risk of accidental door opening.

[0030] The existing in-vehicle opening device for a sliding door of an automobile lacks a driving mechanism capable of unlocking the limit lock. To solve this problem, in the embodiments provided by the present application, the in-vehicle opening device for a sliding door of an automobile includes a first unlocking member 10. The first unlocking member 10 is provided on the bottom plate 1, and the first unlocking member 10 is used to unlock the limit lock. When the door is closed, the limit lock remains in the locked state to prevent accidental opening of the door when the vehicle encounters strong winds or impacts. When the door needs to be opened, the limit lock can be first opened through the first unlocking member 10, and then the in-vehicle opening device for the sliding door can be driven to open the door.

[0031] Refer to Figure 1 and Figure 4As shown, the first unlocking member 10 includes a first cable 101. The first cable 101 is disposed on the bottom plate 1. The steel wire rope inside the first cable 101 can move along a first preset path. The first preset path is the trajectory along which the steel wire rope of the first cable 101 pulls the limit lock to unlock the limit lock. One end of the steel wire rope of the first cable 101 is connected to the first lever 3 through a first buckle 102, and the other end of the steel wire rope of the first cable 101 is connected to the limit lock; the first buckle 102 facilitates connecting the steel wire rope of the first cable 101 to the first lever 3. When the inner opening handle 2 moves in the second direction D2 (i.e., the counterclockwise direction), the first lever 3 rotates synchronously in the second direction D2, and the first buckle 102 moves synchronously with the rotation of the first lever 3, thereby pulling the steel wire rope of the first cable 101 to move along the first preset path to unlock the limit lock. After the limit lock is unlocked, the main lock can be opened by moving the inner opening handle 2 in the first direction D1.

[0032] During the unlocking process of the limit lock, the first elastic restoring member 9 is elastically deformed by the acting force of the first lever 3 to accumulate elastic acting force. When the external force applied to the inner opening handle 2 disappears, the first elastic restoring member 9 applies the accumulated elastic acting force to the first lever 3, driving the first lever 3 to rotate in the first direction D1, driving the steel wire rope of the first cable 101 to return to the initial position (the position before the limit lock is unlocked), and further resetting the limit lock.

[0033] When it is necessary to unlock the main lock from the outside of the vehicle door, in the embodiment provided by the present application, referring to Figure 1 and Figure 5 As shown, the inner opening device of the vehicle sliding door further includes a second unlocking member 12. The second unlocking member 12 is connected to an external opening handle (not shown), and the main lock is unlocked by applying an acting force to the external opening handle to drive the second unlocking member 12.

[0034] The second unlocking member 12 includes an external opening lever buckle 121, a second lever 122, a third pin shaft 123, and a first connecting rod 124. The external opening lever buckle 121 can move along a third direction D3, and the second lever 122 can move along a second direction D2.

[0035] The external opening lever buckle 121 is connected to the external opening handle. The external opening lever buckle 121 is disposed on the second lever 122. The third pin shaft 123 is disposed on the bottom plate 1. One end of the second lever 122 is sleeved on the third pin shaft 123, the other end of the second lever 122 is connected to one end of the first connecting rod 124, and the other end of the first connecting rod 124 is connected to the first swing arm 4.

[0036] When an external force acts on the outward-opening handle, the outward-opening lever buckle 121 moves along the third direction D3 under the action of the outward-opening handle, thereby driving the second lever 122 to move along the second direction D2 (i.e., the counterclockwise direction). Under the action of the second lever 122, the first connecting rod 124 pulls the first swing arm 4 to move along the first direction D1 (i.e., the clockwise direction), thereby driving the first rocker arm 5 to move along the second direction D2, and finally realizing the unlocking of the main lock.

[0037] The other end of the first connecting rod 124 is connected to the first swing arm 4 through the second buckle 125. When the first connecting rod 124 moves, it can pull the first swing arm 4 to move along the first direction D1 through the second buckle 125. Through the connection of the second buckle 125, the connection strength between the first connecting rod 124 and the first swing arm 4 can be improved. Before the main lock is unlocked, it cannot be directly unlocked due to the limitation of the limit lock. Therefore, when opening the main lock from outside the vehicle door, at least the limit lock needs to be unlocked first, and then the second unlocking member 12 is used to unlock.

[0038] In a feasible implementation manner, the inboard opening device of the vehicle sliding door further includes a third unlocking member 13. The third unlocking member 13 is arranged on the bottom plate 1, and the third unlocking member 13 is used to unlock the limit lock. When it is necessary to unlock the main lock from outside the vehicle door, the main lock and the limit lock need to be unlocked simultaneously through the second unlocking member 12 and the third unlocking member 13 to open the vehicle door.

[0039] The third unlocking member 13 includes a second cable 131. One end of the steel wire rope of the second cable 131 is connected to the first swing arm 4 through a third buckle 132. The third buckle 132 facilitates the connection between the steel wire rope of the second cable 131 and the first swing arm 4. The other end of the steel wire rope of the second cable 131 is connected to the limit lock. The steel wire rope of the second cable 131 can move along a second preset path, and the second preset path is the trajectory along which the steel wire rope of the second cable 131 pulls the limit lock to unlock the limit lock.

[0040] When the external force on the outward-opening handle causes the outward-opening lever buckle 121 to move along the third direction D3, the second lever 122 rotates along the second direction D2. Through the driving of the second lever 122, the first connecting rod 124 moves, thereby driving the first swing arm 4 to rotate along the first direction D1. As the first swing arm 4 rotates, the third buckle 132 pulls the steel wire rope of the second cable 131 to move along the second preset path, thereby unlocking the limit lock.

[0041] After the vehicle door is opened using the outward-opening handle, when the external force on the outward-opening handle disappears, the main lock and the limit lock need to be reset. Therefore, the third unlocking member 13 further includes a second elastic restoring member 133. One end of the second elastic restoring member 133 is connected to the first swing arm 4, and the other end of the second elastic restoring member 133 is connected to the bottom plate 1 to apply an elastic acting force to the first swing arm 4 to reset the limit lock.

[0042] During the movement of the first swing arm 4 in the first direction D1, the second elastic restoring member 133 is elastically deformed under the action of the first swing arm 4 to store elastic acting force. When the external force applied to the outward-opening handle disappears, the second elastic restoring member 133 applies the stored elastic acting force to the first swing arm 4, driving the first swing arm 4 to move in the opposite direction of the first direction D1. As a result, the first rocker arm 5 moves in the opposite direction of the second direction D2. At the same time, when the first swing arm 4 moves in the opposite direction of the first direction D1, it can drive the steel wire rope of the second cable 131 to return to the initial position, so that the main lock and the limit lock are reset simultaneously.

[0043] Preferably, the second elastic restoring member 133 is a spring. One end of the spring is connected to the first swing arm 4, and the other end of the spring is connected to the bottom plate 1. During the movement of the first swing arm 4 in the first direction D1, the spring is stretched to store elastic acting force. When the external force applied to the outward-opening handle disappears, the spring applies the elastic acting force to the first swing arm 4, causing the first swing arm 4 to move in the opposite direction of the first direction D1.

[0044] In other embodiments, the second elastic restoring member 133 can adopt other structures or components that can apply elastic acting force to the first swing arm 4, which are not limited herein.

[0045] When there are children in the vehicle, in order to prevent the main lock from being unlocked due to accidental touch and the door being opened, in the embodiments provided by the present application, the inward-opening device of the vehicle sliding door further includes a locking member 14. The locking member 14 can move along a third preset path. When the locking member 14 is located at the starting end of the third preset path, the first lever 3 is kept connected to the first swing arm 4. When the locking member 14 is located at the end of the third preset path, the first lever 3 is disconnected from the first swing arm 4. By moving the locking member 14 along the third preset path, the connection state between the first lever 3 and the first swing arm 4 is controlled. When the locking member 14 is located at the starting end of the third preset path, the first lever 3 is kept connected to the first swing arm 4. Therefore, when the inward-opening handle 2 is driven, the door can be opened. When the locking member 14 is located at the end of the third preset path, the first lever 3 is disconnected from the first swing arm 4, that is, the transmission path between the first lever 3 and the first swing arm 4 is cut off. Then, when the inward-opening handle 2 is driven, even if the first lever 3 rotates in the first direction D1, it cannot drive the first swing arm 4 to rotate, and the inward-opening handle 2 can only rotate idly and cannot open the door, thereby preventing children from accidentally opening the door and improving safety performance.

[0046] In a feasible embodiment, the locking member 14 includes a locking lever 141 and a locking block 142. The locking block 142 is connected to the locking lever 141. The locking lever 141 can move along the third preset path, and the locking block 142 can move in the fourth direction D4.

[0047] Referring to Figure 6 As shown, when the locking lever 141 is located at the starting end of the third preset path (point A in the figure), the first lever 3 and the first swing arm 4 are connected by a locking block 142 (the locking block 142 is located at point B in the figure). When the locking lever 141 moves along the third preset path, it can drive the locking block 142 to move along the fourth direction D4. When the locking lever 141 is located at the end of the third preset path (point A' in the figure), the connection between the first lever 3 and the first swing arm 4 is released (the locking block 142 is located at point B' in the figure).

[0048] Preferably, a sliding groove 32 is provided on the first lever 3, a stop block 41 is provided on the first swing arm 4, the locking block 142 is connected to the locking lever 141 through a second connecting rod 15, the locking block 142 can slide in the sliding groove 32, and the fourth direction D4 is the extending direction of the sliding groove 32. When the locking lever 141 is located at the starting end of the third preset path, the locking block 142 remains in contact with the stop block 41, so that the first lever 3 and the first swing arm 4 can move synchronously, and thus the car door can be opened. When the locking lever 141 moves along the third preset path, the second connecting rod 15 pulls the locking block 142 to move in the sliding groove 32, so that the locking block 142 gradually separates from the stop block 41. When the locking lever 141 is located at the end of the third preset path, the locking block 142 is completely separated from the stop block 41, and there is no connection relationship between the first lever 3 and the first swing arm 4, and thus the car door cannot be opened by driving the inner opening handle 2.

[0049] The structure, features and effects of the present invention have been described in detail based on the embodiments shown in the drawings. The above are only the preferred embodiments of the present invention, but the present invention is not limited to the scope shown in the drawings. Any changes made according to the concept of the present invention, or modified into equivalent embodiments with equivalent changes, still within the spirit covered by the specification and the drawings, shall be within the protection scope of the present invention.
