Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a door unlocking device and a vehicle. Background Technology

[0002] With the increase in the number of vehicles and the continuous improvement in vehicle power performance, the frequency of traffic accidents is also gradually increasing. For serious traffic accidents, the most important thing is to provide timely rescue and medical transport for the occupants.

[0003] Most existing vehicles have automatic door locking functions. Once locked, the door's opening mechanism on the outside is disconnected from the unlocking mechanism, preventing the door from being unlocked from the outside. The automatic door locking system is electronically controlled, requiring power to be supplied before the lock can be released via a control circuit. However, in the event of a severe collision, the vehicle may lose power, preventing the lock from being released and thus hindering timely access to medical care and rescue for occupants.

[0004] Therefore, how to solve or improve the problem of vehicles being unable to open their doors in a timely manner after a power outage following a collision has become an important technical problem for those skilled in the art to solve. Utility Model Content

[0005] In view of this, this application provides a vehicle door unlocking device to solve or improve the problem of not being able to open the vehicle door in time after a power outage due to a vehicle collision.

[0006] In a first aspect, this application provides a vehicle door unlocking device, comprising:

[0016] Optionally, the second limiting part is a protrusion structure provided on the second unlocking member, and the protrusion structure is provided with a guide slope at one end near the inertial member.

[0017] Optionally, under the elastic force of the first elastic member, the inertial member has a tendency to rotate from the second position to the first position;

[0018] The housing is provided with a third limiting part. When the inertial member slides along the first direction to a preset position, the third limiting part abuts against the inertial member.

[0019] Optionally, the housing is provided with a receiving cavity, a partition is connected inside the receiving cavity, and the receiving cavity is divided into a first sliding groove and a second sliding groove by the partition;

[0020] The first slide groove is provided along the first direction, and the first unlocking member is slidably connected in the first slide groove;

[0021] The second slide groove is arranged along the first direction, and the second unlocking member is slidably connected in the second slide groove;

[0022] The partition plate is provided with a first notch. When the counterweight is in the second position, the counterweight extends into the first notch, and the side wall of the first notch is the third limiting part.

[0023] Optionally, the housing includes:

[0024] A bottom shell, wherein the receiving cavity is disposed on the bottom shell and the receiving cavity has an opening;

[0025] A cover is fitted onto the bottom shell and seals the opening. The side of the cover closest to the bottom shell has a second notch and a third notch, which are sequentially arranged along the first direction.

[0026] The counterweight can pass through the second notch to rotate from the first position to the second position, and the counterweight can pass through the third notch to rotate from the second position to the first position.

[0027] Optionally, it also includes:

[0028] The first transmission component has one end connected to the first connecting part and the other end used to connect to the internal unlocking operation component inside the vehicle body.

[0029] And / or, the second transmission component, one end of which is connected to the second connecting part, and the other end of which is used to connect to the external unlocking operation component outside the vehicle body.

[0030] Optionally, it also includes:

[0031] The second elastic element is disposed on the housing and acts on the first unlocking element. Under the elastic force of the second elastic element, the first unlocking element has a tendency to slide away from the first direction.

[0032] And / or, a third elastic element is disposed on the housing and acts on the second unlocking element, under the elastic force of the third elastic element, the second unlocking element has a tendency to slide away from the first direction.

[0033] Secondly, this application also provides a vehicle, including a door, on which any of the door unlocking devices described above are provided.

[0034] This application provides a vehicle door unlocking device, comprising: a housing, a first unlocking member, a second unlocking member, and an inertial member. The first unlocking member is slidably connected to the housing, allowing it to slide along a first direction. A first connecting portion is provided on the first unlocking member. The second unlocking member is slidably connected to the housing, allowing it to slide along the first direction. The inertial member includes a rotating portion and a counterweight portion connected sequentially along its length. After the rotating portion is rotatably connected to the second unlocking member, the counterweight portion can rotate around the rotation center of the rotating portion and the second unlocking member between a first position and a second position. A first limiting portion is provided on the first unlocking member. When the counterweight portion rotates to the second position, the first limiting portion is located on the movement trajectory of the counterweight portion along the first direction.

[0035] After the door unlocking device is installed on the door, the second unlocking component is connected to the external unlocking operating component outside the vehicle body via the second transmission component. Under normal conditions, the counterweight is in the first position, and the inertial force generated by the inertial components during driving and normal vehicle body shaking and bumping will not exceed a threshold. When the vehicle is involved in a collision, the counterweight rotates to the second position due to inertia. At this time, operating the external unlocking operating component outside the vehicle body causes it to pull the second unlocking component along the first direction via the second transmission component. The counterweight then slides in the first direction. Since the first limiting part is located on the movement trajectory of the counterweight in the first direction, as the counterweight continues to slide in the first direction, the counterweight and the first limiting part abut against each other, thereby driving the first limiting part and the first unlocking component to slide in the first direction, which in turn drives the unlocking mechanism to move in the first direction, thus opening the door lock. This ensures that even if the lock cannot be unlocked via the control circuit, the door unlocking device can promptly open the door lock, enabling timely rescue and medical transport for the occupants.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, not all embodiments. 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.

[0049] The following is combined with Figures 1 to 9 This describes an embodiment of the present application.

[0050] According to embodiments of this application, on the one hand, such as Figure 1 and Figure 2 As shown, a vehicle door unlocking device is provided, including: a housing, a first unlocking component 4, a second unlocking component 5, and an inertial component 6.

[0051] The first unlocking component 4 is slidably connected to the housing, allowing it to slide along a first direction X. Driving the door unlocking mechanism along the first direction X will unlock the door. After connecting the first unlocking component 4 to the unlocking mechanism, sliding the first unlocking component 4 along the first direction X will drive the unlocking mechanism along the first direction X, thereby unlocking the door.

[0052] A first connecting part 42 is provided on the first unlocking member 4. The first connecting part 42 is used to connect with the first transmission member 7, so as to directly drive the first unlocking member 4 to slide.

[0053] The second unlocking member 5 is slidably connected to the housing, so that the second unlocking member 5 can slide along the first direction X. A second connecting part 52 is provided on the second unlocking member 5, which is used to connect with the second transmission member 8 to facilitate driving the second unlocking member 5 to slide.

[0054] The inertial element 6 is strip-shaped and includes a rotating part 61 and a counterweight part 62 connected in sequence along its length. After the rotating part 61 is rotatably connected to the second unlocking part 5, the counterweight part 62 can rotate between a first position and a second position around the rotation center of the rotating part 61 and the second unlocking part 5. When the vehicle is impacted, the inertial force generated by the inertial element 6 exceeds a threshold, causing the inertial element 6 to tend to displace. Since the rotating part 61 is rotatably connected to the second unlocking part 5, the inertial element 6 rotates under the action of inertia, causing the counterweight part 62 to rotate from the first position to the second position.

[0055] The first unlocking component 4 is provided with a first limiting part 41. When the counterweight 62 rotates to the second position, the first limiting part 41 is located on the movement trajectory of the counterweight 62 along the first direction X, that is, the counterweight 62 and the first limiting part 41 are limited and engaged in the first direction X. At this time, the counterweight 62 can abut against the first limiting part 41 when it moves along the first direction X. However, when the counterweight 62 is in the first position, the counterweight 62 and the first limiting part 41 are misaligned in the first direction X. At this time, the counterweight 62 cannot contact or abut against the first limiting part 41 when it moves along the first direction X.

[0056] With this configuration, after the door unlocking device is installed on the door, the second unlocking component 5 is connected to the external unlocking operation component outside the vehicle body via the second transmission component 8. Under normal conditions, the counterweight 62 is located in the first position, and the inertial force generated by the inertial component 6 will not exceed the threshold during driving and normal shaking and bumping of the vehicle body.

[0057] It is worth noting that when the inertial force generated by the inertial component 6 exceeds the threshold, a tendency to move will occur.

[0058] When the vehicle collides, the counterweight 62 generates a large inertial force exceeding a threshold, causing the counterweight 62 to rotate to a second position, such as... Figure 3 and Figure 4 As shown. At this time, the external unlocking mechanism is operated from outside the vehicle body, causing the external unlocking mechanism to pull the second unlocking mechanism 5 along the first direction X via the second transmission mechanism 8. The counterweight 62 then slides in the first direction X. Since the first limiting part 41 is located on the movement trajectory of the counterweight 62 along the first direction X, as the counterweight 62 continues to slide in the first direction X, as... Figure 5 and Figure 6 As shown, the counterweight 62 abuts against the first limiting part 41, thereby causing the first limiting part 41 and the first unlocking part 4 to slide in the first direction X, and then drive the unlocking mechanism along the first direction X to open the door lock.

[0059] This ensures that if the door lock cannot be disengaged via the control circuit, the door unlocking device can be used to open the door lock in time, enabling timely rescue and medical transport for the occupants.

[0060] Under normal conditions, the counterweight 62 is located in the first position. Since the counterweight 62 is offset from the first limiting part 41 in the first direction X, when the second unlocking member 5 is driven to slide along the first direction X, the counterweight 62 will not abut against the first limiting part 41, thus preventing the first limiting part 41 and the first unlocking member 4 from sliding in the first direction X. This ensures that the door lock cannot be opened from outside the vehicle using the door unlocking device under normal conditions.

[0061] As an optional embodiment, the second unlocking member 5 is provided with a second limiting part 51. When the counterweight 62 is in the second position, the counterweight 62 is limited and engaged with the second limiting part 51 in the direction of rotation towards the first position, that is, the second limiting part 51 is located on the trajectory of the counterweight 62 rotating towards the first position. Thus, the second limiting part 51 can restrict the counterweight 62 from rotating to the first position, avoiding repeated impacts that would cause the counterweight 62 to rotate to the first position, thereby preventing the first unlocking member 4 from sliding when the second unlocking member 5 is driven to slide. This ensures that the second unlocking member 5 can effectively unlock when sliding in the first direction X.

[0062] In an optional embodiment, the second unlocking member 5 is provided with a rotating shaft 53, the axis of which is parallel to the first direction X. The inertial member 6 is slidably sleeved on the rotating shaft 53. This allows the inertial member 6 to both rotate around and slide along the rotating shaft 53. A first elastic member 1 is provided on the second unlocking member 5. The first elastic member 1 acts on the inertial member 6, and under the elastic force of the first elastic member 1, the inertial member 6 tends to move closer to the second limiting part 51.

[0063] When the counterweight 62 of the inertial member 6 is in the first position, under the elastic force of the first elastic member 1, the counterweight 62 abuts against the second limiting part 51. As the counterweight 62 of the inertial member 6 rotates to the second position, when the counterweight 62 leaves the second limiting part 51, under the elastic force of the first elastic member 1, the inertial member 6 is pushed to move closer to the second limiting part 51 until the counterweight 62 rotates to the second position. At this time, the second limiting part 51 is located between the counterweight 62 in the first position and the counterweight 62 in the second position, thereby restricting the counterweight 62 from rotating to the first position.

[0064] Specifically, a receiving groove 54 is formed on the second unlocking member 5 along the first direction X. The receiving groove 54 has a first sidewall 55 and a second sidewall 56 opposite to each other. A rotating shaft 53 is connected to the sidewall of the receiving groove 54. The rotating shaft 53 can be connected to the first sidewall 55, or to the second sidewall 56, or its two ends can be connected to the first sidewall 55 and the second sidewall 56 respectively. The axis of the rotating shaft 53 is parallel to the first direction X. The rotating part 61 of the inertial member 6 is sleeved on the rotating shaft 53, so that the inertial member 6 can both rotate around the rotating shaft 53 and slide along the rotating shaft 53.

[0065] The first end of the first elastic element 1 is connected to the side of the rotating part 61, and the second end of the first elastic element 1 is connected to the first side wall 55 of the receiving groove 54. The first elastic element 1 can be a spring, and it can be sleeved on the rotating shaft 53 or located on one side of the rotating shaft 53 and parallel to the rotating shaft 53. When the vehicle is involved in a collision, the counterweight 62 rotates from the first position to the second position due to inertia. As the counterweight 62 continues to rotate, when the counterweight 62 leaves the second limiting part 51, the first elastic element 1 pushes the inertial element 6 to slide closer to the second side wall 56 until the counterweight 62 abuts against the second side wall 56 and is located in the fourth position, where the counterweight 62 is located between the second limiting part 51 and the bottom of the receiving groove 54. At this time, the second limiting part 51 is located on the trajectory of the counterweight 62 rotating from the second position to the first position, thereby restricting the movement of the counterweight 62 from the second position to the first position.

[0066] To rotate the counterweight 62 to the first position, the counterweight 62 needs to be pushed towards the first side wall 55 so that the counterweight 62 moves away from the bottom of the second limiting part 51 and the receiving groove 54. This will allow the counterweight 62 to be rotated to the first position and complete the reset of the inertial member 6.

[0067] Furthermore, the second limiting part 51 is a protruding structure provided on the second unlocking member 5, that is, the second limiting part 51 is formed by a protrusion on the second side wall 56. A guide slope 511 is provided on the side of the protruding structure near the inertial member 6. The guide slope 511 is inclined towards the first unlocking member 4 in the direction near the first side wall 55. Under normal conditions, the counterweight part 62 is located in the first position and abuts against the guide slope 511.

[0068] When a vehicle collision occurs, under the influence of inertia, the counterweight 62 slides along the guide ramp 511, thereby the inertial member 6 overcomes the elastic force of the first elastic member 1. The first elastic member 1 is compressed until the counterweight 62 leaves the second limiting part 51. At this time, the first elastic member 1 rebounds and pushes the inertial member 6 to slide closer to the second side wall 56, so that the counterweight 62 is located between the second limiting part 51 and the bottom of the receiving groove 54. At this time, the second limiting part 51 is located on the trajectory of the counterweight 62 rotating from the second position to the first position.

[0069] This configuration facilitates the rotation of the counterweight 62 to the second position.

[0070] In an optional embodiment, under the elastic force of the first elastic element 1, the inertial element 6 tends to rotate from the second position to the first position. The first elastic element 1 can be a torsion spring. When the counterweight 62 of the inertial element 6 rotates from the first position to the second position, the first elastic element 1 undergoes torsional deformation. However, under the limiting action of the second limiting part 51, the counterweight 62 cannot rotate from the first position to the second position, therefore the first torsion spring cannot experience torsional rebound. At this time, pushing the inertial element 6 away from the second limiting part 51 cancels the limiting action of the second limiting part 51, and the first torsion spring can then experience torsional rebound, pushing the inertial element 6 back to the first position.

[0071] A third limiting part 21 is provided on the housing. The second limiting part 51 is offset from the third limiting part 21 in the first direction X, that is, when the second limiting part 51 moves in the first direction X, it will not come into contact with the third limiting part 21.

[0072] When the counterweight 62 is in the second position, it engages with the third limiting part 21 in the first direction X. When the counterweight 62 rotates to the second position, the third limiting part 21 abuts against the inertial member 6 when the inertial member 6 moves to the preset position in the first direction X.

[0073] When a vehicle collision occurs, the counterweight 62 rotates to the second position due to inertia. When unlocking the door using the door unlocking device, the second unlocking member 5 is driven to slide in the first direction X, and the counterweight 62 slides accordingly in the first direction X. Since the first limiting member 41 is located on the movement trajectory of the counterweight 62 along the first direction X, as the counterweight 62 continues to slide in the first direction X to the preset position, the counterweight 62 and the first limiting member 41 are mutually restrained. The continued sliding of the counterweight 62 in the first direction X can drive the first limiting member 41 and the first unlocking member 4 to slide in the first direction X, thereby driving the unlocking mechanism to move in the first direction X, thus opening the door lock.

[0074] After unlocking the car door, the second unlocking component 5 can be driven to continue sliding in the first direction X, as shown. Figure 7 and Figure 8 As shown, after the counterweight 62 abuts against the third limiting part 21, the inertial member 6 can no longer move in the first direction X. Thereafter, it continues to drive the second unlocking member 5 to slide in the first direction X, causing the inertial member 6 to move relative to the pivot 53 towards the direction closer to the first sidewall 55. Figure 9 As shown, the counterweight 62 moves away from the bottom of the second limiting part 51 and the receiving groove 54. At this time, the second limiting part 51 loses its limiting effect on the counterweight 62, and the first torsion spring rebounds with torque, thereby driving the inertial member 6 to rotate until the counterweight 62 rotates to the first position, completing the reset of the inertial member 6.

[0075] This configuration allows the inertial component 6 to be reset for reuse, reducing operating costs.

[0076] The housing contains a receiving cavity, within which a partition 22 is installed, separating the receiving cavity to form a first sliding groove 23 and a second sliding groove 24. The first sliding groove 23 is arranged along a first direction X, meaning its length direction is aligned with the first direction X. A first unlocking member 4 is connected to and can slide along the first sliding groove 23. The second sliding groove 24 is also arranged along the first direction X, meaning its length direction is aligned with the first direction X. A second unlocking member 5 is connected to and can slide along the second sliding groove 24.

[0077] A third notch 221 is made on the partition 22. When the counterweight 62 rotates to the second position, the counterweight 62 extends into the third notch 221 and enters the first groove 23. When the counterweight 62 moves along the first direction X, the counterweight 62 moves within the first notch 31. The side wall of the third notch 221 is the third limiting part 21. When the counterweight 62 moves to abut against the side wall of the third notch 221, it can no longer move along the first direction X. As the counterweight 62 continues to move, under the limiting action of the third limiting part 21, the inertial member 6 moves away from the first direction X relative to the axis of rotation 53 and leaves the second limiting part 51.

[0078] Furthermore, the housing includes a bottom shell 2 and a cover 3. A receiving cavity is disposed on the bottom shell 2, the receiving cavity having an opening, and a partition 22 is connected within the receiving cavity and divides the receiving cavity into a first sliding groove 23 and a second sliding groove 24. The opening is divided into a first opening and a second opening. After the cover 3 is placed on the bottom shell 2, the cover 3 closes the first opening and the second opening.

[0079] A first notch 31 and a second notch 32 are provided on the side of the cover 3 near the first sliding groove 23. The first notch 31 and the second notch 32 are arranged sequentially along the first direction X.

[0080] The second unlocking member 5 can slide along the second slide groove 24 between the third and fourth positions. Normally, the second unlocking member 5 is located in the third position, at which point the first notch 31 lies on the trajectory of the counterweight 62 of the inertial member 6 as it rotates from the first position to the second position. Thus, the counterweight 62 can pass through the first notch 31 and rotate to the second position, preventing the cover 3 from interfering with the rotation of the counterweight 62.

[0081] When the second unlocking member 5 moves to the fourth position along the first direction X, the counterweight 62 abuts against the third limiting part 21, and the second notch 32 is located on the trajectory of the counterweight 62 of the inertial member 6 rotating from the second position to the first position. After the second unlocking member 5 moves to the fourth position, it continues to move along the first direction X until the counterweight 62 leaves the space between the second limiting part 51 and the bottom of the receiving groove 54. At this time, the counterweight 62 loses its limiting effect, the first torsion spring experiences torsional rebound, thereby driving the inertial member 6 to rotate, and the counterweight 62 can rotate from the second position through the second notch 32 to the first position. This avoids interference from the cover 3 on the rotation of the counterweight 62.

[0082] This design eliminates the need to consider the interference of the cover 3 on the counterweight 62, meaning there is no need to leave a large gap between the cover 3 and the pivot 53, which allows the overall shell to be smaller and the structure to be more compact and stable.

[0083] The width of the first notch 31 should be greater than the thickness of the counterweight 62.

[0084] As an optional embodiment, the door unlocking device further includes a first transmission member 7. One end of the first transmission member 7 is connected to the first connecting portion 42, and the other end of the first transmission member 7 is connected to an internal unlocking operating member inside the vehicle body. When the operator operates the internal unlocking operating member inside the door, the first unlocking member 4 is driven to move in the first direction X via the first transmission member 7, thereby unlocking the door.

[0085] The internal unlocking mechanism can be a door handle installed on the inside of the door.

[0086] With this configuration, the door unlocking device can serve as a mechanism for unlocking the doors from inside the vehicle, eliminating the need for the original internal door unlocking mechanism.

[0087] The first transmission component 7 includes a first sleeve 71 and a first pull wire 72 passing through the first sleeve 71. A first stop 73 is provided at the first end of the first pull wire 72. The first connecting part 42 is a first placement cavity provided in the first unlocking component 4. A first through groove communicating with the first placement cavity is provided on the first unlocking component 4. The first sleeve 71 is connected to the housing, the first pull wire 72 passes through the first through groove, and the first stop 73 is located in the first placement cavity.

[0088] After connecting the first pull cable 72 to the inner unlocking mechanism located on the inside of the door, the inner unlocking mechanism can drive the first pull cable 72 to move along the first direction X. The first stop 73 abuts against the inner wall of the first placement cavity, thereby pulling the first unlocking member 4 to slide along the first direction X.

[0089] As an optional embodiment, the door unlocking device further includes a second elastic element 10. The second elastic element 10 is disposed on the housing and acts on the first unlocking element 4. When the second unlocking element 4 moves in the first direction X, the second elastic element 10 undergoes elastic deformation. At this time, under the elastic force of the second elastic element 10, the first unlocking element 4 tends to move away from the first direction X.

[0090] Specifically, the second elastic element 10 is disposed within the first slide groove 23. The first end of the second elastic element 10 is connected to the first unlocking element 4, and the second end of the second elastic element 10 is connected to the housing. When the first pull cable 72 pulls the first unlocking element 4 to slide within the first slide groove 23 along the first direction X, the second elastic element 10 undergoes elastic deformation along the first direction X. When the first pull cable 72 is released, the second elastic element 10 rebounds and pushes the first unlocking element 4 to slide away from the first direction X, thus resetting its position.

[0091] The second elastic element 10 is a spring. It can be disposed on one side of the first pull wire 72 and parallel to the first pull wire 72. Alternatively, it can be sleeved on the first pull wire 72, in which case the first end of the second elastic element 10 is connected to the outer wall of the first unlocking member 4, and the second end of the second elastic element 10 is connected to the end face of the first sleeve 71.

[0092] As an optional implementation, the door unlocking device further includes a second transmission member 8. One end of the second transmission member 8 is connected to the second connecting portion 52, and the other end of the second transmission member 8 is connected to an inner unlocking operating member outside the vehicle body. When an operator operates the outer unlocking operating member from outside the door, the second unlocking member 5 is driven to move in the first direction X via the second transmission member 8.

[0093] The external unlocking mechanism can be a door handle installed on the outside of the car door.

[0094] The second transmission component 8 includes a second sleeve 81 and a second pull wire 82 passing through the second sleeve 81. A second stop 83 is provided at the first end of the second pull wire 82. The second connecting part 52 is a second placement cavity provided within the second unlocking component 5. A second through groove communicating with the second placement cavity is provided on the second unlocking component 5. The second sleeve 81 is connected to the housing, the second pull wire 82 passes through the second through groove, and the second stop 83 is located within the second placement cavity.

[0095] After connecting the second pull cable 82 to the external unlocking mechanism located on the outside of the door, the external unlocking mechanism can drive the second pull cable 82 to move along the first direction X. The second stop 83 abuts against the inner wall of the second placement cavity, thereby pulling the second unlocking member 5 to slide along the first direction X.

[0096] As an optional embodiment, the door unlocking device further includes a third elastic element 11. The third elastic element 11 is disposed on the housing and acts on the second unlocking member 5. When the second unlocking member 5 moves in the first direction X, the third elastic element 11 undergoes elastic deformation. At this time, under the elastic force of the third elastic element 11, the second unlocking member 5 has a tendency to slide away from the first direction X.

[0097] Specifically, the third elastic element 11 is disposed within the second slide groove 24. The first end of the third elastic element 11 is connected to the second unlocking element 5, and the second end of the third elastic element 11 is connected to the housing. When the second pull cable 82 pulls the second unlocking element 5 to slide within the second slide groove 24 along the first direction X, the third elastic element 11 undergoes elastic deformation along the first direction X. When the second pull cable 82 is released, the third elastic element 11 rebounds and pushes the second unlocking element 5 to slide away from the first direction X, thus resetting its position.

[0098] The third elastic element 11 is a spring. It can be set on one side of the second pull wire 82 and parallel to the second pull wire 82. Alternatively, it can be sleeved on the second pull wire 82, in which case the first end of the third elastic element 11 is connected to the outer wall of the second unlocking member 5, and the second end of the third elastic element 11 is connected to the end face of the second sleeve 81.

[0099] It is worth noting that the second transmission member 8 and the second transmission member 8 can be provided simultaneously. The second elastic member 10 and the third elastic member 11 can also be provided simultaneously.

[0100] Regarding the connection between the first unlocking member 4 and the unlocking mechanism, the first unlocking member 4 is provided with a third connecting part 43, which is connected to the unlocking mechanism via a third transmission member 9. When the first unlocking member 4 slides in the first direction X, the unlocking mechanism can be driven to unlock via the third transmission member 9.

[0101] The third transmission component 9 includes a third sleeve 91 and a third pull wire 92 passing through the third sleeve 91. A third stop 93 is provided at the first end of the third pull wire 92. The third connecting part 43 is a third placement cavity located within the second unlocking component 5. The second unlocking component 5 has a third through groove communicating with the third placement cavity. The third sleeve 91 is connected to the housing, the third pull wire 92 passes through the third through groove, and the third stop 93 is located within the second placement cavity.

[0102] After the third pull cable 92 is connected to the unlocking mechanism, when the first unlocking component 4 moves along the first direction X, the third pull cable 92 can pull the unlocking mechanism, thereby unlocking the mechanism.

[0103] According to an embodiment of this application, another aspect provides a vehicle including a door, wherein the door is provided with any of the aforementioned door unlocking devices. The technical effects of this vehicle are the same as those of the door unlocking devices and will not be described further.

[0104] It is worth noting that for an inertial block, its movement in the first and second positions can also be translation. That is, when a vehicle collides, under the action of inertia, the inertial block can translate from the first position to the second position.

[0105] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by this application.
