[0016] In the description of the present invention, it is necessary to understand that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0017] In the figure, there are a tailgate skylight 100, a driven assembly 200, a vehicle body hinge 201, a hinge shaft 202, a first driven wheel 203, a second driven wheel 204, a door hinge 205, a main driving wheel 300, a driven slide rail 400, a main driving slide rail 500, a strut 600, a door lock 700, a strut bracket 800, a strut shaft 900, a lock buckle 1000, and a top cover 1001.

[0018] like Figure 1 As shown, the automobile tailgate opening mechanism includes a tailgate sky door 100, a driven component 200, a main driving wheel 300, a driven slide rail 400 and a main driving slide rail 500. The driven component 200 is fixed to the left end of the tailgate sky door 100 and installed on the driven slide rail 400, so that the driven component 200 can slide along the driven slide rail 400, and the right end of the tailgate sky door 100 is installed with a door lock 700. A support rod 600 is installed under the tailgate sky door 100, and the left end of the support rod 600 is hingedly connected to the middle part of the tailgate sky door 100, so that the support rod 600 can move the entire tailgate around the hinge point. The tailgate skygate 100 is propped up, the main driving wheel 300 is fixed to the lower right end of the support rod 600 and installed on the main driving slide rail 500, the main driving wheel 300 is connected to a motor and is used to provide power for opening the tailgate skygate 100, the motor can drive the main driving wheel 300 to slide along the main driving slide rail 500, the upper right end of the support rod 600 is connected to the door lock 700, and the main driving wheel 300 can push the tailgate skygate 100 to slide open or flip open when working. Here, this patent can switch to realize the two functions of sliding open or flip open of the tailgate skygate 100 by working with a main driving wheel 300.

[0019] Specifically, the driven assembly 200 includes a body hinge 201, a hinge shaft 202, a first driven wheel 203, a second driven wheel 204 and a door hinge 205. The first driven wheel 203 and the second driven wheel 204 are installed at one end of the body hinge 201, and the other end is connected to the door hinge 205 through the hinge shaft 202. The hinged door component is fixed to the left end of the tailgate sky door 100, so that the left end of the tailgate sky door 100 can rotate around the hinge shaft 202. A support rod bracket 800 and a support rod shaft 900 are provided at the middle hinge of the support rod 600 and the tailgate sky door 100. The left end of the support rod 600 is connected to the support rod bracket 800 through the support rod shaft 900. A door lock 700 is installed on the right end of 00, and a lock buckle 1000 is installed on the right end of the support rod 600, and the lock buckle 1000 is engaged with the door lock 700. A main driving wheel 300 is installed at the lower part of the right end of the support rod 600, and the main driving wheel 300 is installed on the main driving slide rail 500. Here, since the lock buckle 1000 is engaged with the door lock 700, the tailgate sky door 100 can be separated from the support rod 600 or combined into a whole with the support rod 600. One side of the tailgate sky door 100 has a top cover 1001, and the driven slide rail 400 is located under the top cover 1001 and is arranged along the extension direction of the top cover 1001. The driven slide rail 400 is located at the lower part of the tailgate sky door 100 and is arranged along the extension direction of the tailgate sky door 100.

[0020] The motor is responsible for providing power for opening the tailgate sky door 100. The driven wheel has no power source. When the tailgate sky door 100 is closed, the main driving wheel 300 has no power output and is locked, and remains relatively still with the main driving wheel 300 slide rail. Figure 2 As shown, when the tailgate sky door 100 slides and opens during operation, the driven wheel and the main driving wheel 300 are unlocked, and the door lock 700 remains locked by cooperating with the lock buckle 1000. At this time, the motor drives the main driving wheel 300 to work and push the tailgate sky door 100 to slide and open along the slide rail toward the top cover 1001, thereby realizing the sliding opening function of the tailgate sky door 100. Figure 3 As shown, when the tailgate skylight 100 needs to be flipped open, the main drive wheel 300 and the door lock 700 are unlocked, the driven wheel remains locked, the motor drives the main drive wheel 300 to work and push the tailgate skylight 100 to flip open around the hinge shaft 202, thereby realizing the sliding and flipping opening function of the tailgate skylight 100.

[0021] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
