[0027] Example 1

[0028] See attached Figure 1-3 A skylight with a fixed opening angle comprises: a skylight body which can be opened and closed outwards and is composed of a top cover 1 and a mounting frame 2, a support arm 3 arranged on the skylight body for controlling the opening and closing angle, and a slide groove 4 for cooperating with one end of the support arm 3 for displacement, the top cover 1 and the end of the mounting frame 2 are rotatably connected, and a locking assembly 6 is further arranged at the end of both the top cover 1 and the mounting frame 2 near the slide groove 4; one end of the support arm 3 is connected to the top cover 1, and the other end is connected to the mounting frame 2;

[0029] Among them, one end of the support arm 3 is a rotating connection for changing the support angle of the support arm 3; the other end of the support arm 3 is provided with a sliding member 31, and the sliding member 31 is assembled with a slide groove 4 set on the sunroof body. The slide groove 4 is provided with a plurality of limit grooves 40, and the limit grooves 40 are used to fix the displacement position of the sliding member 31.

[0030] Preferably, the slide groove 4 is arranged on the mounting frame 2, one end of the support arm 3 is rotatably connected with the top cover 1 through a rotating shaft, and a sliding member 31 is arranged on the other end of the support arm 3 and is slidably assembled on the mounting frame 2 through the slide groove 4. When one end of the sliding member 31 arranged on the support arm 3 slides in the slide groove 4 of the mounting frame 2 to the limiting groove 40, the limiting groove 40 fixes the sliding member 31, and a triangular stable structure is formed between the fixed support arm 3, the mounting frame 2 and the top cover 1. The connection position of one end of the support arm 3 and the top cover 1 is fixed, and the connection position of the top cover 1 and the mounting frame 2 is fixed. When the position of the other end of the support arm 3 is fixed through the limiting groove 40, a triangle is formed. The triangle can adjust the opening and closing angle between the top cover 1 and the mounting frame 2 as the support arm 3 slides through the sliding member 31. By assembling the sliding member 31 with the limiting groove 40, the opening and closing angle between the top cover 1 and the mounting frame 2 can be fixed until the next adjustment.

[0031] Preferably, one end of the top cover 1 and one end of the mounting frame 2 are connected via a hinge 5, and the other end of the top cover 1 and the other end of the mounting frame 2 are provided with a locking assembly 6 for locking the top cover 1 and the mounting frame 2 in a closed state.

[0032] Preferably, both ends of the sliding member 31 are provided with elastic limiters, which are composed of an elastic column 311 and a spring 312, and the elastic column 311 is assembled on the sliding member 31 through the spring 312. The elastic column 311 applies a force to the slide groove 4 through the spring 312, so that the elastic column 311 always fits in the slide groove 4, so that when the elastic column 311 moves to the position where the limit groove 40 is provided on the slide groove 4, it can also fit in the limit groove 40, so that the upper cover 1 can be better fixed.

[0033] Furthermore, the hinge 5 for connecting the top cover 1 and the mounting frame 2 may be any connection structure that allows the top cover 1 and the mounting frame 2 to rotate coaxially.

[0034] Preferably, the locking assembly 6 includes a hook 61 and a lock buckle 62 , the hook 61 is arranged on the end of the mounting frame 2 away from the hinge 5 , the lock buckle 62 is arranged on the end of the top cover 1 away from the hinge 5 , and the lock buckle 62 is arranged corresponding to the hook 61 .

[0035] Preferably, the third limiting groove 41 disposed on the slide groove 4 at the end farthest from the hinge 5 is configured as a hook-shaped structure, and the sliding member 31 closes and locks the top cover 1 and the mounting frame 2 through the hook-shaped structure.

[0036] Further preferably, a lock 611 is provided at the top of the hook 61, a guide slope 612 is provided on the side of the lock 611 away from the top, and a return spring 613 is provided adjacent to the guide slope 612;

[0037] Among them, the hook 61 is set to be L-shaped, and the bent part of the hook 61 is a lock 611, which is used to be assembled with the lock buckle 62. A guide slope 612 is set at the end away from the lock 611. The guide slope 612 is used to cooperate with the sliding member 31 to change the working state of the locking assembly, wherein the reset spring 613 is used to limit the hook 61, mainly to make the guide slope 612 always in the position where the elastic column 311 can work normally, to avoid the situation where the guide slope 612 is stuck due to excessive displacement.

[0038] Reference Figure 3 and Figure 4Specifically, the guide slope 612 is set to be L-shaped, and the angle at the corner of the L-shape of the guide slope 612 tends to 90°. During the closing process of the sunroof, when the elastic column 311 on the sliding member 31 is displaced through the sliding groove 4 to contact an edge of the guiding slope 612 set at the bottom, the edge that was originally set parallel to each other is changed to a vertical setting. In this process, the latch 611 approaches the lock buckle 62 adjacent to the upper part of the sliding member 31 until the elastic column 311 falls into the third limiting groove 41 at the end to achieve locking; during the opening process of the sunroof, when the elastic column 311 is displaced upward in the sliding groove 4, the elastic column 311 contacts the other edge of the guiding slope 612 set at the bottom, and the edge that was originally set parallel to each other is changed to a vertical setting. When the elastic column 311 comes out of the guiding slope 612 on the sliding groove 4, the latch 611 moves in a direction away from the lock buckle 62 to release the locked state.

[0039] Reference Figure 2 , Figure 5 and Figure 6 In one embodiment, three limit grooves 40 are set on the slide groove 4, which are a first limit groove 42 for fixing the opening and closing angle between the top cover 1 and the mounting frame 2 to 5°, a second limit groove 43 for fixing the opening and closing angle between the top cover 1 and the mounting frame 2 to 50°, and a third limit groove 41 for fixing the opening and closing angle between the top cover 1 and the mounting frame 2 to 0°. The arc of the slide groove 4 allows the sliding member 31 to gradually transition from upward movement to leftward movement.

[0040] Furthermore, the limiting groove 40 is arranged in a conical socket shape.

[0041] The working principle of the present invention is as follows:

[0042] After the end positions of the top cover 1 and the mounting frame 2 are fixed, they can only rotate. After one end of the support arm 3 is fixed to the position of the top cover 1 or the mounting frame 2, the other end of the sliding member 31 is limited in position in the slide groove 4 by the limiting groove 40. The top cover 1, the mounting frame 2 and the support arm 3 form a triangular structure. The distance from the connection point between the top cover 1 and the mounting frame 2 to the connection point between the support arm 3 and the top cover 1 or the mounting frame 2 and the length of the support arm 3 itself are fixed, but the other end of the support arm 3 can be displaced in the slide groove through the sliding member 31 and fixed in position by the limiting groove 40, which is equivalent to that one side length of the triangle can be changed. According to the Pythagorean theorem, the inner angle of the triangular structure formed by the top cover 1, the mounting frame 2 and the support arm 3 changes with the position of the end of the support arm 3 provided with the sliding member 31 in the slide groove 4.

[0043] By providing the elastic column 311, the sliding member 31 can cooperate with the spring 312 to better fix the top cover 1 when it falls into the limiting groove 40. By providing a plurality of limiting grooves, the top cover 1 can be opened at different angles.

[0044] The opening and closing of the hook 61 and the lock buckle 62 can be achieved by the displacement of the elastic column 311 at the end of the slide groove 4 and the cooperation with the guide inclined surface 612 on the hook 61 .

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
