Description

Technical Field

[0001] The invention relates to the technical field of automobile sunroofs, and in particular to a sunroof self-locking structure. Background Art

[0002] With the rapid development of the automobile industry, cars are generally equipped with sunroofs. Sunroofs not only provide adequate ventilation, but also have good lighting performance. In addition, ordinary sunroofs have low manufacturing costs and are widely popular.

[0003] At present, the lifting mechanism used for lifting the sunroof of a car is mainly composed of parts such as a slide rail, a lifting arm, a lifting arm, a mechanism limiter, and a main slider. The bottom of the lifting arm contacts the boss of the mechanism limiter in the slide rail, a fulcrum on the upper part of the lifting arm slides in the curved groove on the mechanism lifting arm, and the other fulcrum is fixed in the slide rail. The three parts of the mechanism lifting arm, the slide rail and the lifting arm form a triangle. The lifting principle is to directly drive the mechanism limiter to move through the main slider, so that the lifting arm rotates on the rear end boss of the mechanism limiter to change the triangle vertex angle, so that the lifting arm forms different inclination angles, and the sunroof is lifted or lowered. However, in the prior art, the limit device on the mechanism limiter, such as the inner clip, will slide under the action of external force, resulting in abnormal lifting or sinking of the sunroof, and it is easy to fail and get stuck during operation. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies of the above-mentioned technology and provide a self-locking structure for a sunroof, which can effectively prevent the inner clip from sliding abnormally and avoid causing the sunroof to warp or sink abnormally.

[0005] To achieve the above-mentioned purpose, a self-locking structure of a skylight designed in the present invention includes a self-locking slider and an inner clip arranged on the side of the self-locking slider, the two elastic arms of the inner clip are respectively arranged on both sides of the self-locking slider, the ends of the two elastic arms are provided with a clamp, and the inner and outer sides of the clamp are provided with a protruding structure, the self-locking slider is provided with a first accommodating groove, a self-locking pin is installed in the first accommodating groove, a spring is provided between the self-locking pin and the bottom of the first accommodating groove, a vertical self-locking plate is provided on the outer end face of the self-locking pin, the self-locking pin extends out of the first accommodating groove, the two elastic arms of the inner clip are fully opened, and the two side end faces of the self-locking plate are abutted against the protruding structure on the inner side of the clamp.

[0006] Preferably, the end surfaces of both sides of the self-locking plate located between the clamp and the outer end surface both protrude outward to form a boss, and the protruding structure on the inner side of the clamp presses against the boss. The clamp presses against the boss on the self-locking plate, thereby preventing the self-locking pin from being completely ejected by the spring and disengaging from the first accommodating groove when the sunroof is lifted.

[0007] Preferably, a sliding groove is opened at the bottom length direction of the first receiving groove, and a guide rail matching the sliding groove is provided at the bottom of the self-locking pin to prevent the self-locking pin from rotating or displacing when moving in the first receiving groove, which is also beneficial for the self-locking pin to slide more stably in the first receiving groove.

[0008] Preferably, a second accommodating groove for accommodating the spring is opened on the inner end surface of the self-locking pin, so that the spring can be positioned more accurately when pushing the self-locking pin, and the spring will not be displaced when compressed and deformed by force.

[0009] Preferably, a bevel groove is provided in the middle of one end of the self-locking plate away from the outer end surface to prevent the main slider from interfering with the self-locking plate when pushing the self-locking pin.

[0010] Preferably, the self-locking pin is a cylindrical structure, which facilitates the sliding of the self-locking pin in the first receiving groove.

[0011] Preferably, the outside of the clamp is covered with a plastic head, which matches the outer contour shape of the self-locking plate and plays a clamping role.

[0012] Preferably, slide rail bosses are symmetrically arranged on both sides of the self-locking slider along the length direction to facilitate the self-locking slider to slide on the slide rail.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. When the sunroof is lifted, the self-locking pin is ejected by the elastic force of the spring, and the self-locking plate abuts against the clamp to prevent the elastic arm of the inner clamp from sliding out of the slot of the slide rail. When the sunroof is lowered, the main slider pushes the self-locking pin into the first accommodating groove, and the self-locking plate no longer abuts against the clamp. The elastic arm of the inner clamp slides out of the slot of the slide rail and interlocks with the main slider. The self-locking plate prevents the inner clamp from sliding abnormally, thus avoiding abnormal lifting and sinking of the sunroof.

[0015] 2. The clamping head presses against the boss on the self-locking plate, thereby preventing the self-locking pin from being completely ejected by the spring and disengaging from the first receiving groove when the sunroof is lifted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the sunroof self-locking structure of the present invention comprises a self-locking slider 3 and an inner clip 2 arranged on the side of the self-locking slider 3, two elastic arms 4 of the inner clip 2 are respectively arranged on both sides of the self-locking slider 3, and the ends of the two elastic arms 4 are provided with a clamping head 5, and the inner and outer sides of the clamping head 5 are provided with a convex structure. The self-locking slider 3 is provided with a first accommodating groove 14, and a self-locking pin 6 is installed in the first accommodating groove 14. In this embodiment, the self-locking pin 6 is a cylindrical structure, and a spring 7 is provided between the self-locking pin 6 and the bottom of the first accommodating groove 14. A second accommodating groove 15 for accommodating the spring 7 is opened on the inner end surface of the self-locking pin 6, and a vertical self-locking plate 9 is provided on the outer end surface 8 of the self-locking pin 6. Figure 2 As shown, the self-locking pin 6 extends from the first receiving groove 14 under the action of the spring 7, the two elastic arms 4 of the inner clip 2 are fully opened, and the two side end surfaces of the self-locking plate 9 abut against the protruding structures on the inner side of the clamp 5, abutting against the two protruding structures on the inner side of the clamp 5. In addition, the two side end surfaces of the self-locking plate 9 located between the clamp 5 and the outer end surface 8 are both protruded outward to form a boss 10, and the protruding structure on the inner side of the clamp 5 abuts against the boss 10.

[0026] Combination Figure 4 As shown, a slide groove is opened at the bottom length direction of the first accommodating groove 14, a guide rail 11 matching the slide groove is provided at the bottom of the self-locking pin 6, and an inclined groove 12 is provided in the middle of the end away from the outer end surface 8 on the self-locking plate 9.

[0027] In addition, if Figure 1 As shown, the outside of the clamp 5 is covered with a plastic head, which matches the outer contour shape of the self-locking plate 9, and the self-locking slider 3 is symmetrically provided with slide rail bosses 13 along the length direction on both sides.

[0028] In this embodiment, the self-locking pin 6 is an injection molding device, and the self-locking slider 3 is made of plastic, which can effectively reduce the cost of parts manufacturing and reduce the noise generated when the entire mechanism is running.

[0029] When this embodiment is used, combined with Figure 2 and Figure 3 As shown, when the sunroof is in a closed and stationary state, the self-locking slider 3 is installed in the slide groove of the slide rail 16 through the slide rail boss 13, and the slide rail boss 13 can slide along the slide groove in the slide rail 16. The elastic arm 4 of the inner clip 1 is in a clamped state due to the inward squeezing effect of the slide rail 16, and the protruding structure on the inner side of the clamp 5 of the inner clip 1 clamps the main slider 17, completing the interlocking with the main slider 17;

[0030] When the sunroof is opened, the main slider 17 starts to move, and at the same time drives the inner clip 1 to move. When the inner clip 1 runs to the slot of the slide rail 16, the elastic arm 4 has an outward curvature and has outward tension after being clamped. At this time, the elastic arm 4 opens, and the protruding structure on the outside of the clamp 5 is clamped into the slot of the slide rail 16. The main slider is disengaged from the inner clip 1, and the inner clip 1 stops running, and then the sunroof is lifted up. At this time, the self-locking pin 6 pops out under the push of the elastic force of the spring 7, and its self-locking plate 9 will resist the protruding structure on the inside of the clamp 5 of the inner clip 1 to prevent the protruding structure on the outside of the clamp 5 from disengaging from the slot of the slide rail 16, thereby locking the inner clip 1, and the protruding structure on the inside of the clamp 5 also resists the boss 10 on the self-locking plate 9 to prevent the self-locking pin 6 from being completely ejected by the spring 7 and disengaging from the first When the sunroof is closed, the main slider 17 moves in the opposite direction, and first contacts the self-locking pin 6, pushing the self-locking pin 6 to move, so that it overcomes the elastic force of the spring 7 and returns to the first accommodating groove 14. At this time, the self-locking plate 9 of the self-locking pin 6 no longer resists the raised structure on the inner side of the clamp 5, and the self-locking pin 6 no longer locks the inner clip 1. When the main slider 17 continues to move, it pushes the inner clip 1 to move, and the clamp 5 of the inner clip 1 slides out of the slot of the slide rail 16. Since the elastic arm 4 is squeezed inward by the slide rail 16 and is in a clamped state, the raised structure on the inner side of the clamp 5 of the inner clip 1 clamps the main slider 17, completing the interlocking with the main slider 17. The main slider 17 and the inner clip 1 run as a whole in the slide rail, and the sunroof completes the sinking action.

[0031] The self-locking structure of the sunroof of the present invention prevents abnormal sliding of the inner clip 1 by self-locking the main slider 17 and the inner clip 1 and mutual self-locking of the inner clip 1 and the self-locking pin 6, thereby avoiding abnormal lifting and sinking of the sunroof. The structure is simple and the stability is high.

[0032] The above shows and describes the basic principles and main structural features of the present invention. The present invention is not limited to the above examples. 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. The scope of protection of the present invention is defined by the attached claims and their equivalents.
