[0028] When a vehicle door has two or more door locks that need to be opened at the same time, it is difficult for the multiple door locks to remain open at the same time due to the different layout positions of the multiple door locks, and the normal opening of the vehicle door cannot be ensured.

[0029] With this in mind, referring to Figures 1 to 5 , this application provides a vehicle unlocking mechanism and vehicle that can be used to simultaneously maintain multiple door locks unlocked on a single vehicle door. By providing a hovering function on the unlocking dial, this application can maintain multiple door locks in the unlocked state, thereby ensuring the normal opening of the vehicle door. This is described in detail below using specific embodiments.

[0030] Please refer to Figure 1, which shows an exploded view of a vehicle unlocking mechanism provided by the present application. In one embodiment of the present application, the vehicle unlocking mechanism may include a mounting bracket 100, a fixed housing 200, a turntable 300, a limit rocker 400, and an elastic member 500. The mounting bracket 100 may be attached to a vehicle door. The fixed housing 200 may be attached to the mounting bracket 100 and located on a side of the mounting bracket 100 away from the vehicle door. The turntable 300 may be rotatably connected to the fixed housing 200. The turntable 300 may define a guide slot 310, as shown in Figure 5. The guide slot 310 may be located on a side of the turntable 300 proximal to the fixed housing 200. The limit rocker 400 may be connected between the mounting bracket 100 and the turntable 300. Specifically, one end of the limit rocker 400 is rotatably connected to the mounting bracket 100, while the other end of the limit rocker 400 is engageable within the guide slot 310. The elastic member 500 can be connected between the fixed housing 200 and the rotating disk 300. When the rotating disk 300 rotates, the elastic member 500 can be used to restore the rotating disk 300 to its original position. In this embodiment, the rotating disk 300 rotates, which can drive the other end of the limiting rocker 400 to move along the guide groove 310.

[0031] As shown in Figure 1, in one embodiment of the present application, the vehicle unlocking mechanism may further include a rotating shaft 600. The rotating shaft 600 may be installed at the center of the fixed housing 200. The turntable 300 may be rotatably connected to the rotating shaft 600 to enable the turntable 300 to rotate relative to the fixed housing 200. The elastic member 500 may be a return spring, for example, a torsion spring or a spiral spring. When the elastic member 500 adopts a torsion spring, the elastic member 500 may be sleeved on the rotating shaft 600. The two ends of the elastic member 500 are respectively clamped on the fixed housing 200 and the turntable 300. It can be seen that the elastic member 500 can be used to generate an elastic force to reset the turntable 300 when the turntable 300 rotates around the rotating shaft 600. In this embodiment, when the turntable 300 is in the initial position, that is, the turntable 300 is not rotated and all door locks are in the locked state, the elastic member 500 will be in a neutral state without compression or stretching; when the turntable 300 is in the unlocked position, that is, the turntable 300 is rotated to the maximum limit and all door locks are in the unlocked state, the elastic member 500 will be in the maximum deformation state.

[0032] Please refer to Figure 2, which shows a front view of a vehicle unlocking mechanism according to one embodiment of the present application. In one embodiment of the present application, the mounting bracket 100 can be stamped from a metal sheet and provided with a plurality of fixing holes 110. The number of fixing holes 110 can range from two to five. For example, the mounting bracket 100 can have three fixing holes, located on the left, top, and right sides of the mounting bracket 100. The mounting bracket 100 can be mounted to the vehicle door using fasteners such as bolts, rivets, or clips.

[0033] Referring to Figures 1 and 2, in one embodiment of the present application, at least two sub-brackets may be provided on the mounting bracket 100. The sub-brackets may be formed by stamping and bending, or may be connected to the bracket body of the mounting bracket 100 by welding. In this embodiment, a first sub-bracket 120 and a second sub-bracket 130 are provided on the mounting bracket 100. The first sub-bracket 120 and the second sub-bracket 130 may be perpendicular to the bracket body of the mounting bracket 100. The first sub-bracket 120 may be provided with a mounting hole 121, and the mounting hole 121 may be a through hole. The second sub-bracket 130 may be provided with a mounting groove 131. In some embodiments, the mounting groove 131 may be a through groove.

[0034] Referring to Figures 1 and 2 , in one embodiment of the present application, the turntable 300 may be cylindrical and may be provided with a latching slot 320 and a connecting slot 330. The latching slot 320 may be provided on the cylindrical curved surface of the turntable 300, i.e., the latching slot 320 may be located at the junction of the outer contours of the two side surfaces of the turntable 300. The connecting slot 330 may be provided on a side of the turntable 300 away from the fixed housing 200, with a certain distance between the connecting slot 330 and the center of rotation of the turntable 300.

[0035] Referring to Figure 2 , in one embodiment of the present application, the vehicle unlocking mechanism further includes a handle cable 700 and a door lock cable. The handle cable 700 can be connected to the turntable 300. One end of the door lock cable can be connected to the connection slot 330, and the other end of the door lock cable can be connected to one or more door locks. As can be seen, when a passenger pulls the handle cable 700, the handle cable 700 drives the turntable 300 to rotate, which in turn drives the door lock cables to unlock all door locks.

[0036] Referring to Figures 1 and 2, in one embodiment of the present application, the handle cable 700 may include a buffer block 710, a cable 720, a handle ring 730, and a limiting sleeve 740. The buffer block 710 may be mounted on the first sub-bracket 120. Specifically, the buffer block 710 may be mounted in the mounting hole 121. A through hole is provided on the buffer block 710. The buffer block 710 may be made of a material such as rubber. One end of the cable 720 may be fixedly connected to the turntable 300, and the cable 720 may surround a cylindrical contour surface and be embedded in the cylindrical contour surface; the other end of the cable 720 passes through the buffer block 710 and is connected to the handle ring 730. The limiting sleeve 740 may be disposed around the cable 720 and fixed relative to the cable 720. The limiting sleeve 740 may be located between the buffer block 710 and the handle ring 730. As can be seen, the cable 720 is fixedly connected to the turntable 300 and is embedded in the slot 320. Therefore, when the passenger pulls the handle ring 730, the cable 720 moves in the same direction as the handle ring 730, and the cable 720 drives the turntable 300 to rotate. When the passenger releases the handle ring 730, the turntable 300 rotates to its original position under the action of the elastic member 500.

[0037] 1 and 2 , in one embodiment of the present application, the cable head at one end of the door lock cable can be connected to the connecting groove 330 , and the cable sleeve at the same end can be snapped onto the mounting groove 131 of the second sub-bracket 130 .

[0038] Please refer to Figure 3, which shows a schematic diagram of the structure of a position-limiting rocker 400 in one embodiment of the present application. In one embodiment of the present application, the position-limiting rocker 400 may include a swing shaft 410, a swing arm 420, and a stopper 430. The swing shaft 410 is rotatably connected to the mounting bracket 100, and one end of the swing arm 420 may be connected to the swing shaft 410. The stopper 430 may be connected to the swing arm 420 and located on the side of the swing arm 420 closest to the turntable 300. The stopper 430 may be engaged within the guide groove 310. When the turntable 300 rotates, the stopper 430 moves along the guide groove 310, thereby causing the swing arm 420 to swing about the swing shaft 410. In this embodiment, the swing shaft 410 may be fitted with a second elastic member. The second elastic member is configured to cause the swing arm 420 to rotate toward the center of the turntable 300.

[0039] Furthermore, in one embodiment of the present application, a clearance space is provided on the fixed housing 200. The clearance space may be located on a side of the fixed housing 200 facing the chuck 300. The clearance space may be used to accommodate the swinging motion of the limit rocker 400.

[0040] Please refer to Figure 4, which shows a schematic diagram of the motion trajectory of the limit rocker 400 in one embodiment of the present application. It can be seen that the limit block 430 is engaged within the guide groove 310 and moves along the guide groove 310 as the turntable 300 rotates. In one embodiment of the present application, the centerline of the guide groove 310 on the turntable 300 can be a closed curve. This closed curve can be divided into three parts: an unlocking curve 311, a hovering curve 312, and a locking curve 313. One end of the unlocking curve 311 can be connected to one end of the locking curve 313; the other end of the unlocking curve 311 can be connected to one end of the hovering curve 312; and the other end of the locking curve 313 can be connected to the other end of the hovering curve 312. The unlocking curve 311 and the locking curve 313 are approximately arc-shaped, and the junction of the unlocking curve 311 and the locking curve 313 forms a vertex angle 314. The locking curve 313 can be located between the unlocking curve 311 and the center of the turntable 300. The hovering curve 312 is approximately U-shaped, with its ends connecting the unlocking curve 311 and the locking curve 313. The concave direction of the U-shaped curve is toward the top angle 314, thereby forming a hovering angle 315. In this embodiment, the junction of the unlocking curve 311 and the hovering curve 312 can be set as the first extreme position 316 for the engagement of the limit rocker 400 with the guide groove 310, and the junction of the hovering curve 312 and the locking curve 313 can be set as the second extreme position 317 for the engagement of the limit rocker 400 with the guide groove 310.

[0041] Please refer to Figures 4 to 5. Figure 5 is a schematic diagram of the initial position of the turntable 300 in one embodiment of the present application. In one embodiment of the present application, when all door locks are in the locked state, the turntable 300 is in the initial position, and the limit block 430 is located at the top corner 314. When the vehicle unlocking mechanism is unlocked, the passenger pulls the handle cable 700 and releases it. Specifically, the passenger pulls the handle cable 700 until the limit block 430 moves to the first extreme position 316 and then releases it. During this unlocking process, the handle cable 700 first drives the turntable 300 to rotate counterclockwise, and the connecting groove 330 drives the door lock cable to open all door locks on the vehicle door. The elastic member 500 deforms to generate elastic force, causing the turntable 300 to have a tendency to return to its initial position. After the stopper 430 moves along the unlocking curve 311 from the top angle 314 to the first limit position 316, the turntable 300 rotates under the action of the elastic member 500. Because the swing arm 420 tends to rotate toward the center of the turntable 300, the stopper 430 moves from the first limit position 316 to the hovering angle 315 and stops at the hovering angle 315. This ensures that the stopper rocker 400 cooperates with the hovering curve 312, keeping the turntable 300 in the unlocking position and all the door locks in the unlocked state.

[0042] Referring to Figures 4 and 5 , in one embodiment of the present application, when the vehicle unlocking mechanism is locked, the passenger pulls the handle cable 700 again and releases it. Specifically, the passenger pulls the handle cable 700 until the stopper 430 moves to the second extreme position 317 and then releases it. During this locking process, the handle cable 700 first drives the turntable 300 to rotate counterclockwise. Because the swing arm 420 tends to rotate toward the center of the turntable 300, the stopper 430 moves to the second extreme position 317, thus moving the stopper 430 from the hovering curve 312 to the locking curve 313. The elastic member 500 releases its elastic force, causing the turntable 300 to rotate clockwise to its initial position, and the stopper 430 moves along the locking curve 313 to the top corner 314. The connecting slot 330 releases the door lock cable, closing all the door locks.

[0043] The present application also provides a vehicle, which may include a vehicle body and multiple doors mounted on the vehicle body. Each door may include one or more door locks and a vehicle unlocking mechanism. The vehicle unlocking mechanism may be the vehicle unlocking mechanism described in any of the above embodiments. The vehicle unlocking mechanism may be connected to multiple door locks, allowing multiple door locks to remain unlocked simultaneously.

[0044] In summary, the present application provides a vehicle unlocking mechanism and vehicle that can be used to simultaneously maintain multiple door locks unlocked on a single vehicle door. This application has the advantages of a simple structure and high reliability. By providing a hovering function on the unlocking dial, this application can maintain multiple door locks in the unlocked state, thereby ensuring the normal opening of the vehicle door.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concepts disclosed in this application shall be covered by the claims of this application.
