Figure 1 The lower end of the connecting rod 3 is connected to the rotating direction piece 41. When the connecting rod 3 moves downward, it will drive the rotating direction piece 41 to rotate clockwise. The rotating direction piece 41 is connected to one end of the unlocking wire 5, thereby pulling the unlocking wire 5 to start the sliding door main converter 2 and then perform the unlocking operation.

[0005] However, in order to enhance the customer experience of the sliding door glass lifting system of MPV models, the sliding door glass needs to be able to be completely lowered to below the sliding door water cut. However, the sliding door structure described above will interfere with the sliding door front converter 4 in the Z direction during the sliding door glass lowering process, and cannot meet the requirement of completely lowering the sliding door glass. If the sliding door front converter 4 is offset in the X direction of the sliding door glass surface, the sliding door glass surface will become narrower, which will in turn affect the sliding door's X-direction shape and cannot meet the shape and appearance requirements. If the sliding door front converter 4 is further lowered a certain distance toward the ground in the Z direction, the vehicle height in the Z direction will increase, which is also not feasible.

[0043] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0044] Please refer to Figure 3 , Figure 3 This is a schematic diagram of a specific embodiment of the unlocking device for the sliding door lock provided by the present invention.

[0045] like Figure 3 As shown, the sliding door lock for locking the sliding door includes a sliding door main lock 300 and a sliding door full-open limit lock 200, and the unlocking device of the sliding door lock includes a sliding door main converter 100, and the sliding door main converter 100 is connected to a first wire draw 402 and a second wire draw 403, and the first wire draw 402 and the second wire draw 403 are respectively connected to the sliding door main lock 300 and the sliding door full-open limit lock 200. When the sliding door main converter 100 is started, the first wire draw 402 or the second wire draw 403 can be pulled to unlock the corresponding sliding door main lock 300 and the sliding door full-open limit lock 200 to achieve unlocking. This embodiment mainly provides a solution for starting the sliding door main converter 100.

[0046] Please continue to combine Figure 3 , and refer to Figure 4-5 understand, Figure 4 for Figure 3 A structural diagram of the position of the middle handle 10; Figure 5 for Figure 4 Schematic diagram of the coordination of the middle handle 10, the rotating member 30, the spring and the rotating shaft 60.

[0047] The unlocking device in this embodiment also includes a handle 10, a rotating part 30 and an unlocking wire 401, wherein the rotating part 30 is connected to one end of the unlocking wire 401, and the other end of the unlocking wire 401 is connected to the sliding door main converter 100. In addition, the rotating part 30 and the handle 10 are linked. When the handle 10 is opened, the handle 10 can drive the rotating part 30 to rotate. When the rotating part 30 rotates, it can directly pull the unlocking wire 401 to start the sliding door main converter 100, thereby achieving the purpose of unlocking the sliding door lock.

[0048] Figure 3 、 4 Given a coordinate system, the Z direction is the height direction, the X direction is the length direction of the vehicle, and the Y direction is the width direction of the vehicle. Figure 4 、 5 It is understood that the unlocking device includes a base 20, a handle 10 and a rotating member 30 are both mounted on the base 20, and the rotating member 30 is specifically connected to the base 20 by rotating around the axis of the X direction. Figure 5 The rotating shaft 60 of the rotating member 30 is shown in FIG. 6 , and the rotating shaft 60 extends along the X direction. Thus, the rotating member 30 can rotate around the rotating shaft 60 in the vertical plane YZ. The handle 10 is also provided with a toggle portion 101. Figure 4 As shown, the toggle portion 101 and the holding portion of the handle 10 are located on both sides of the base 20 along the Y direction, and Y+ is defined as the inner side and Y- is defined as the outer side. The holding portion of the handle 10 is located on the outer side of the base 20, and the toggle portion 101 is located on the inner side of the base 20. When an outward Y-direction force F is applied to the handle 10, that is, when the handle 10 is pulled outward, the toggle portion 101 moves outward along the Y-direction synchronously.

[0049] Continue to refer Figure 5 It is understood that the toggle portion 101 of the handle 10 is in contact with the rotating member 30, and the toggle portion 101 is located in the Y+ direction of the rotating member 30, that is, located on the inner side of the handle 10. In this way, when the toggle portion 101 moves outward in the Y- direction with the handle 10, it can press the rotating member 30 along the Y- direction, thereby driving the rotating member 30 to rotate around the X direction, and correspondingly pulling the unlocking wire 401 connected thereto.

[0050] like Figure 5 As shown, the rotating member 30 includes a first part and a second part distributed on both sides of its rotation axis, specifically distributed on both sides of the rotating shaft 60 along the Z direction, and the mass of the second part of the rotating member 30 is greater than the mass of the first part. In this way, the second part plays the role of a counterweight, and a certain external force needs to be added to achieve the purpose of driving the second part to rotate, thereby increasing safety. The rotating member 30 here can also be defined as a counterweight block. Figure 5In the embodiment, the second portion with a relatively large mass is located below the rotating shaft 60, that is, in the Z-direction, and the first portion with a relatively small mass is located above the rotating shaft 60, that is, in the Z+ direction. The toggle portion 101 contacts the first portion located above and is located inside the first portion. In this way, when the handle 10 is pulled outward in the Y-direction, the toggle portion 101 presses the first portion of the rotating member 30 along the Y-direction, thereby forcing the rotating member 30 to rotate counterclockwise. Figure 4 In the direction of rotation shown, the second portion will correspondingly tilt upward, pulling the corresponding unlocking wire 401 upward to unlock the lock. The toggle portion 101 and the rotating member 30 are merely in a contact and pressing linkage relationship, without the need for actual connection, which is simple to set up and not prone to interference, but in fact, connection is also possible.

[0051] It can be understood that the rotating member 30 in this solution is not limited to the structural design of the counterweight block. The handle 10 and the unlocking wire 401 are respectively connected to the handle 10 on both sides of the rotating shaft 60, so as to convert the starting operation of the handle 10 into the pulling action of the unlocking wire 401 in the desired direction. Figure 4 In the embodiment, the pulling operation of the handle 10 in the Y-direction is converted into pulling the unlocking wire 401 along the Z+ direction.

[0052] It can be seen that in this embodiment, compared with the background technical solution, the setting of the rotating part 30 is improved and designed, and the unlocking wire 401 is directly connected to the bottom of the rotating part 30. The position where the handle 10 drives the rotating part 30 to rotate is located above the rotating part 30. In this way, when the handle 10 is pulled, the rotating part 30 can directly pull the unlocking wire 401, and there is no need to set a converter in front of the sliding door, thereby avoiding the glass lifting system from being affected by the converter in front of the sliding door. Without affecting the X-axis shape of the sliding door and the Z-axis height of the entire vehicle, the layout space of the unlocking device of the sliding door lock is released to achieve the sliding door glass lowering opening requirement, thereby realizing the lightweight and low-cost sliding door lock system.

[0053] It can be understood that this embodiment mainly directly connects the rotating member 30 and the unlocking wire 401, so that the unlocking wire 401 is directly pulled under the drive of the handle 10 to activate the sliding door main converter 100. Therefore, the rotating member 30 does not actually limit the direction of pulling the unlocking wire 401, as long as the unlocking wire 401 can be directly pulled and the sliding door main converter 100 can be activated at the same time. However, in this embodiment, the unlocking wire 401 is directly connected to the first part of the rotating member 30 located below the rotating shaft 60. When the rotating member 30 rotates under the drive of the handle 10, the first part of the rotating member 30 also happens to tilt upward, thereby pulling the unlocking wire 401 upward. This arrangement is suitable for the current arrangement of the unlocking wire 401, combined with Figure 1 、 3Understanding the layout of the unlocking wire, the unlocking wire 3 is arranged below the handle 1 and the sliding door main converter 3. When one end of the unlocking wire 3 linked to the handle 1 is directly connected to the position of the handle 1, the end of the unlocking wire 401 linked to the handle 1 needs to move upward before it can be pulled. At this time, there is no need to make changes to the layout of the unlocking wire 401 to start the sliding door main converter 100, only the direction of the linkage between the rotating part 30 and the handle 10 needs to be adjusted.

[0054] Furthermore, in this embodiment, the handle 10 is pulled outward along the Y-direction, so that the linkage portion 101 presses against the first portion of the rotating member 30, thereby driving the rotating member 30 to rotate, which is equivalent to pushing the rotating member 30. It is understood that the linkage between the handle 10 and the rotating member 30 is not limited to this. For example, the handle 10 may also be provided with a pulling portion that is connected to the rotating member 30 to synchronously pull the rotating member 30 to rotate. Furthermore, the handle 10 is not limited to being pulled outward to drive the rotating member 30 to rotate; it may also be pushed inward to drive the rotating member 30 to rotate. This is not a limitation of the present embodiment, as long as the rotating member 30 and the handle 10 are linked.

[0055] like Figure 4 As shown, the unlocking device further includes a first limiting groove 501 for limiting the position of the ferrule 401a at the end of the unlocking wire 401. Since the rotating member 30 in this embodiment rotates about the X-axis to pull the unlocking wire 401 upward, the first limiting groove 501 can extend in the Z-direction, i.e., the vertical direction. The provision of the first limiting groove 501 can locate the position of the ferrule 401a at the end of the unlocking wire 401, ensuring more stable and reliable pulling of the unlocking wire 401, and preventing the unlocking wire 401 from rotating with the rotating member 30 and affecting the pulling effect. Figure 4 In the embodiment, an annular groove is provided on the outer periphery of the clamping sleeve 401a at the end of the unlocked wire drawing 401, and an annular bayonet is formed in the first limiting groove 501 to be clamped into the annular groove in the up and down directions to limit the movement of the clamping sleeve 401a and achieve the limiting purpose, so that the wire drawing body extending from the clamping sleeve 401a in the unlocked wire drawing 401 can be smoothly pulled by the rotating part 30.

[0056] like Figure 4 As shown, a limit block 50 is provided at the bottom of the base 20 near the rotating member 30, and a first limit groove 501 is provided in the limit block 50. The limit block 50 and the base 20 can be a separate structure or an integrated structure. The main structure of the limit block 50 is a grid structure, and the first limit groove 501 runs through the grid structure from top to bottom. The corresponding layer of the grid structure in the first limit groove 501 forms an annular bayonet to snap into the annular groove of the clamping sleeve 401a at the end of the wire drawing. The limit block 50 of this structure has a certain strength and is easy to form an annular bayonet, which is convenient for unlocking the clamping sleeve 401a of the wire drawing 401. However, it is obvious that the first limit groove 501 can also be formed in other ways. Figure 4In order to achieve the insertion of the ferrule 401a, the notch of the first limiting groove 501 faces the unlocking wire 401 so that the unlocking wire 401 can be inserted.

[0057] In addition, if Figure 5 As shown, the second part of the rotating member 30 is provided with a second limiting groove 301, and the end of the wire drawing body extending from the clamping sleeve 401a is provided with a clamping head, which is clamped into the second limiting groove 301 and can rotate freely in the second limiting groove 301, but will not be separated from the second limiting groove 301, so as to provide sufficient flexibility and avoid twisting of the wire drawing body.

[0058] Furthermore, the unlocking device further comprises an elastic member, such as Figure 5 As shown, the elastic member is a torsion spring 70, which is disposed throughout the rotating shaft 60. The elastic member provides elastic force to prevent the rotating member 30 from rotating and pulling the unlocking wire 401. This not only facilitates the automatic return of the rotating member 30 after the external force on the handle 10 is removed, but also helps prevent the rotating member 30 from accidentally rotating and unlocking under the action of an unexpected external force, thereby improving safety. It should be understood that the elastic member here is not limited to the torsion spring 70, as long as it can provide elastic force to return the rotating member 30 to the unlocked state. Since the action of the rotating member 30 is rotation, the torsion spring 70 precisely provides the elastic force to limit rotation, so the torsion spring 70 is preferably used. However, it is clear that other elastic members, such as the pulling of a cylindrical spring, can also provide the elastic force to limit the rotation of the rotating member 30.

[0059] This embodiment further provides a vehicle comprising a sliding door and a sliding door lock for locking the sliding door, and further comprising the unlocking device for the sliding door lock described in any of the above embodiments. The vehicle may be an MPV. This vehicle obviously has the same technical effects as the above unlocking device, and no further description is given.

The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
