The present application discloses an emergency opening and closing device in one embodiment, as shown in FIG1 , comprising a base plate 1 and an unlocking link 4 for linking an internal emergency unlocking mechanism 2 and an external emergency unlocking mechanism 3 , wherein the unlocking link 4 is used to connect with a vehicle door lock;

The unlocking link 4 is rotatably connected to the base plate 1 , and the internal emergency unlocking mechanism 2 and the external emergency unlocking mechanism 3 are respectively linked to the unlocking link 4 , the internal emergency unlocking mechanism 2 is arranged on the inner side of the vehicle door, and the external emergency unlocking mechanism 3 is arranged on the outer side of the vehicle door.

Further, as shown in FIG1 , a first rotating shaft 14 is provided on the base plate 1, and the unlocking link 4 is rotatably connected to the first rotating shaft 14, and the unlocking link 4 can rotate around the first rotating shaft 14. The unlocking link 4 is connected to the door lock switch, and preferably, the vehicle door lock includes a sliding door front lock, a sliding door rear lock, and a sliding door limit lock, and the sliding door front lock, the sliding door rear lock, and the sliding door limit lock can be synchronously controlled by the unlocking link 4 to unlock. Optionally, the door lock switch can also include a combination of one or more of the front door lock, the rear door lock, and the back door lock, so that the unlocking link 4 can synchronously control the front door, the rear door, and the back door to unlock.

The door lock switch set at the remote end can be connected to the unlocking link 4 through the flexible cable, reducing the restrictions on the arrangement position of the emergency opening and closing device and reducing the constraints on the door interior shape. Multiple door lock switches are respectively connected to the unlocking link 4 through flexible cables. When the internal emergency unlocking mechanism 2 or the external emergency unlocking mechanism 3 is triggered, the internal emergency unlocking mechanism 2 or the external emergency unlocking mechanism 3 drives the unlocking link 4 to rotate, and the unlocking link 4 pulls the flexible cable, and the flexible cable triggers multiple door lock switches to unlock at the same time, so as to ensure that multiple door lock switches can be quickly unlocked at the same time in an emergency.

In the present application, since the internal emergency unlocking mechanism 2 is arranged on the inner side of the vehicle door and the external emergency unlocking mechanism 3 is arranged on the outer side of the vehicle door, the occupants in the vehicle can perform emergency unlocking through the internal emergency unlocking mechanism 2 in an emergency situation, and the rescue personnel outside the vehicle can also perform emergency unlocking through the external emergency unlocking mechanism 3, thereby improving the safety of the vehicle.

In some embodiments of the present application, as shown in FIG. 1 , an emergency link 5 is further included, and the internal emergency unlocking mechanism 2 is connected to the emergency link 5 through an internal flexible cable 23 , one end of the internal flexible cable 23 is connected to the internal emergency unlocking mechanism 2 , and the other end is connected to the emergency link 5 , as shown in FIG. 2 , a first linkage block 51 is provided on the emergency link 5 ;

When the internal emergency unlocking mechanism 2 is triggered, the internal emergency unlocking mechanism 2 pulls the emergency link 5 to rotate through the internal flexible cable 23, and the first linkage block 51 on the emergency link 5 contacts the unlocking link 4 and drives the unlocking link 4 to rotate to trigger unlocking.

Furthermore, as shown in Figure 2, the emergency link 5 is rotatably connected to the first rotating shaft 14, and the emergency link 5 and the unlocking link 4 can both rotate around the first rotating shaft 14, wherein the emergency link 5 and the internal emergency unlocking mechanism 2 are connected by an internal flexible cable 23, which can make the arrangement of the emergency opening and closing device more flexible, so that the internal emergency unlocking mechanism 2 does not need to be set at a position close to the emergency opening and closing device, thereby reducing the constraints on the door interior shape.

As shown in FIG2 , the emergency link 5 is arranged above the unlocking link 4, the first linkage block 51 is arranged on one side of the emergency link 5 and is bent toward the unlocking link 4, and the first linkage block 51 is located on one side of the unlocking link 4. Therefore, when the occupant triggers the internal emergency unlocking mechanism 2, the internal emergency unlocking mechanism 2 pulls the emergency link 5 around the first rotating shaft 14 to rotate in the unlocking direction (counterclockwise in FIG1 ) through the flexible cable. During the rotation of the emergency link 5, the first linkage block 51 contacts the side of the unlocking link 4 and can push the unlocking link 4 to rotate in the unlocking direction and trigger unlocking.

In addition, since the first linkage block 51 is only arranged on one side of the emergency link 5, and the emergency link 5 is arranged above the unlocking link 4, when the emergency link 5 is reset, the emergency link 5 rotates in the direction opposite to the unlocking direction, and the first linkage block 51 on the emergency link 5 does not contact the unlocking link 4. At this time, no transmission is transmitted between the emergency link 5 and the unlocking link 4.

When the external emergency unlocking mechanism 3 is triggered, the external emergency unlocking mechanism 3 drives the linkage assembly 6 to move through the external flexible cable 31 , and the linkage assembly 6 drives the unlocking link 4 to rotate.

Furthermore, by connecting the linkage assembly 6 and the external emergency unlocking mechanism 3 through the external flexible cable 31, the arrangement of the emergency opening and closing device can be made more flexible, so that the external emergency unlocking mechanism 3 does not need to be arranged near the emergency opening and closing device, thereby reducing the constraints on the door interior shape. The external emergency unlocking mechanism 3 can be an external handle of the door.

In some embodiments of the present application, as shown in FIGS. 2 to 4 , the linkage assembly 6 includes a first linkage rod 61 and a second linkage rod 62, the first linkage rod 61 and the second linkage rod 62 are respectively rotatably connected to the base plate 1, a second linkage block 611 is provided on the first linkage rod 61, the second linkage rod 62 is linked with the unlocking link 4, and the external emergency unlocking mechanism 3 is connected to the first linkage rod 61;

When the external emergency unlocking mechanism 3 is triggered, the external emergency unlocking mechanism 3 drives the first linkage rod 61 to rotate, the second linkage block 611 on the first linkage rod 61 contacts the second linkage rod 62 and drives the second linkage rod 62 to rotate, and the second linkage rod 62 drives the unlocking link 4 to rotate.

The second linkage block 611 is arranged on one side of the first linkage rod 61 and is bent toward the second linkage rod 62, and the second linkage block 611 is located on one side of the second linkage rod 62. When the external emergency unlocking mechanism 3 is triggered to act, the external emergency unlocking mechanism 3 drives the first linkage rod 61 to rotate in the unlocking direction (counterclockwise as shown in FIG. 1 ). When the first linkage rod 61 rotates, the second linkage block 611 can contact the side of the second linkage rod 62 and can push the second linkage rod 62 to rotate in the unlocking direction, and the second linkage rod 62 drives the unlocking link 4 to rotate in the unlocking direction to trigger unlocking.

In addition, since the second linkage block 611 is only arranged on one side of the first linkage rod 61, and the first linkage rod 61 is arranged above the second linkage rod 62, when the first linkage rod 61 is reset, the first linkage rod 61 rotates in a direction opposite to the unlocking direction, and the second linkage block 611 on the first linkage rod 61 does not contact the second linkage rod 62. At this time, no transmission is transmitted between the first linkage rod 61 and the second linkage rod 62.

In some embodiments of the present application, as shown in FIG. 1 , an electric unlocking mechanism 7 is further included, and the electric unlocking mechanism 7 is connected to the second linkage rod 62 .

Furthermore, the electric unlocking mechanism 7 can directly drive the second linkage rod 62 to rotate. Preferably, the electric unlocking mechanism 7 is connected to the second linkage rod 62 through a flexible cable. The occupant can control the electric unlocking mechanism 7 through a switch button in the vehicle or a remote control. The electric unlocking mechanism 7 drives the second linkage rod 62 to rotate in the unlocking direction, so that the second linkage rod 62 can drive the unlocking link 4 to rotate and trigger the door lock to unlock.

In some embodiments of the present application, as shown in FIG. 1 , a locking mechanism 8 is further included, the locking mechanism 8 includes a protrusion 81 and a driving mechanism 82, the protrusion 81 is slidably disposed on the unlocking link 4, the driving mechanism 82 is connected to the protrusion 81 and is used to drive the protrusion 81 to slide on the unlocking link 4, and the second linkage rod 62 is provided with a push block 612 capable of contacting the protrusion 81;

The locking mechanism 8 includes a locked state and an unlocked state;

As shown in FIG3 , when the locking mechanism 8 is in the locked state, the driving mechanism 82 drives the protrusion 81 to slide to leave the active track of the push block 612, and when the second linkage rod 62 rotates, the push block 612 cannot contact the protrusion 81, and no transmission is performed between the second linkage rod 62 and the unlocking link 4;

As shown in FIG. 4 , when the locking mechanism 8 is in the unlocking state, the driving mechanism 82 drives the protrusion 81 to slide into the active track of the push block 612 . When the second linkage rod 62 rotates, the push block 612 contacts the protrusion 81 and pushes the unlocking link 4 to rotate.

Further, as shown in FIG3 and FIG4, the unlocking link 4 is provided with a first sliding groove 41 arranged along the length direction thereof, the protrusion 81 is slidably arranged in the first sliding groove 41, the driving mechanism 82 is connected to the protrusion 81 and can drive the protrusion 81 to slide in the first sliding groove 41, wherein the push block 612 is arranged on the second linkage rod 62, when the second linkage rod 62 rotates, the push block 612 rotates around the first rotating shaft 14, and when the unlocking link 4 rotates, the protrusion 81 rotates around the first rotating shaft 14. When in the locked state, the driving mechanism 82 drives the protrusion 81 to slide in the direction of the first rotating shaft 14, so that the distance between the protrusion 81 and the first rotating shaft 14 is smaller than the distance between the push block 612 and the first rotating shaft 14, at which time the protrusion 81 is separated from the moving track of the push block 612, so at this time when the second linkage rod 62 is driven to rotate, the push block 612 on the second linkage rod 62 cannot contact the protrusion 81, that is, there is no transmission between the second linkage rod 62 and the unlocking link 4. When in the unlocked state, the driving mechanism 82 drives the projection 81 to slide in the direction away from the first rotating shaft 14. At this time, the distance between the projection 81 and the first rotating shaft 14 is equal to the distance between the push block 612 and the first rotating shaft 14, that is, the projection 81 enters the activity track of the push block 612. At this time, when the second linkage rod 62 is driven to rotate, the push block 612 on the second linkage rod 62 can contact the projection 81 and push the unlocking link 4 to rotate in the unlocking direction to achieve unlocking. By setting the locking mechanism 8, the external emergency unlocking mechanism 3 can be unlocked or locked. When the occupant leaves the vehicle, the projection 81 can be controlled to move to the locked position by operating the driving mechanism 82, so that the second linkage rod 62 and the unlocking link 4 are not transmitted, and the emergency unlocking mechanism set on the outside of the door cannot be used to unlock the door, thereby realizing the anti-theft function.

Furthermore, as shown in FIG. 3 and FIG. 4 , the fourth linkage rod 823 is provided with a second sliding groove 8231 arranged along the length direction thereof, and the projection 81 passes through the first sliding groove 41 and is inserted into the second sliding groove 8231. When locked, the fourth linkage rod 823 rotates in the counterclockwise direction, and the fourth linkage rod 823 drives the projection 81 to slide in the first sliding groove 41 in the direction close to the first rotating shaft 14, and the projection 81 synchronously slides in the second sliding groove 8231 in the direction away from the second rotating shaft.

By inserting the projection 81 into the first sliding groove 41 and the second sliding groove 8231 at the same time, the problem of jamming when switching the locked state or the unlocked state can be avoided.

As shown in FIG. 7 , by operating the sliding door opening component 22 , the internal flexible cable 23 can be driven, and then the door lock is pulled under the pulling force of the internal flexible cable 23 to easily open the door.

As shown in FIG. 7 , in some embodiments, the door opening component 22 includes a spring (not shown) and a sliding block 221 , wherein the sliding block 221 connects the internal flexible cable 23 and the spring.

The spring is fixed on the component support frame 24.

When the sliding block 221 slides on the slide rail of the component support frame 24, the spring is compressed. Specifically, when the sliding block 221 slides, it can pull the internal flexible cable 23 and compress the spring, so that when the user releases the sliding block 221, the spring can be used for reset.

As shown in Figures 6 and 7, the door opening component 22 can be composed of a spring (of course, in order to simplify the figures, Figures 6 and 7 do not show the spring) and a sliding block 221. The spring is located directly below the sliding block 221. Of course, when the sliding block 221 slides on the slide rail, the spring is compressed and the internal flexible cable 23 is pulled downward, thereby driving the door lock to open through the other end of the internal flexible cable 23, so that the door can be easily opened in an emergency.

In addition, after the vehicle door is opened, when the user releases the sliding block 221 , the sliding block 221 can be quickly reset under the action of the spring force without manual reset, which can further improve the operating convenience of the internal emergency unlocking mechanism 2 .

The present application also discloses a vehicle, comprising the above-mentioned emergency opening and closing device.

The above description is only the principle and preferred embodiment of the present application. It should be pointed out that, for ordinary technicians in this field, on the basis of the principle of the present application, several other variations can be made, which should also be considered as the protection scope of the present application.
