Description

Technical Field

[0001] This application relates to the field of building and vehicle components, and in particular to a novel sunroof locking mechanism. Background Technology

[0002] In the fields of construction and vehicles, sunroofs are increasingly widely used. As a core component ensuring the normal opening and closing and stable use of sunroofs, the performance of new sunroof locking mechanisms directly affects user experience and safety. Traditional new sunroof locking mechanisms are mostly simple in structure, typically using only ordinary hinges to connect the sunroof to the mounting base, which has many drawbacks. For example, the fixing method is not stable enough, and long-term use can easily lead to loosening, causing the sunroof to jam or even fall off; the lack of an effective buffering and damping system results in a large impact force when the sunroof is closed, which not only generates significant noise but also accelerates component wear and shortens the mechanism's lifespan; at the same time, existing mechanisms have poor adaptability to different sunroof sizes and installation environments, making it difficult to meet diverse usage needs. Furthermore, some traditional locking mechanisms are inconvenient to maintain, requiring complete replacement when malfunctioning, increasing operating costs. Therefore, there is an urgent need to design a new sunroof locking mechanism with a stable structure, good buffering performance, strong adaptability, and easy maintenance to solve the problems existing in current technology. Utility Model Content

[0003] In view of this, this application proposes a novel sunroof locking mechanism, the structure of which includes: a fixed part, a hinge arm, and a damping buffer. The fixed part includes a hinge cup and a hinge seat. The hinge cup has a cavity in the middle and is fixed to the sunroof frame by screws. The hinge seat is plate-shaped and is installed on the wall by screws. The hinge arm is a hollow cuboid structure with a pin hole at one end, which is connected to the hinge cup by a pin and to the hinge seat by screws. The hinge arm has a snap-fit ​​hole on the opposite side of the hinge seat, and the snap-fit ​​hole has a snap-fit ​​groove structure inside. The damping buffer includes a housing and a damping strip. The housing is a hollow cuboid structure with a through hole on one side and a snap-fit ​​element on the other side. The damping strip is a cuboid structure and is connected to the hinge arm by the snap-fit ​​element.

[0004] In one possible implementation, a guide rail is provided inside the housing, and a guide rail groove matching the guide rail is provided on the damping strip, which is slidably disposed inside the housing.

[0005] In one possible implementation, a return spring is connected to the upper part of the rotatable connection between the hinge arm and the hinge cup.

[0006] In one possible implementation, one end of the spring is connected to a snap-fit ​​element, and the other end of the spring is connected to a spring sheet, which is slidably disposed at the bottom of the snap-fit ​​element.

[0007] In one possible implementation, a bolt hole is provided on the damping strip, and a limiting bolt is provided in the bolt hole.

[0008] In one possible implementation, the housing of the damping strip includes a hook whose shape matches the groove shape of the snap-fit ​​groove.

[0009] In one possible implementation, the spring is made of a rigid plastic material.

[0010] In one possible implementation, the hinge arm is made of stainless steel.

[0011] In one possible implementation, the connecting base plate is provided with at least two bolt fixing holes.

[0012] In one possible implementation, the damping strip is made of plastic.

[0013] The beneficial effects of this utility model are:

[0014] This novel sunroof locking mechanism boasts significant innovative advantages in both structural design and functional implementation. The fixing component employs a cup-shaped hinge cup and a plate-shaped hinge seat, secured to the sunroof frame and wall respectively with screws. This ensures a stable connection while facilitating disassembly and maintenance, adapting to various installation scenarios. The hollow cuboid structure of the hinge arm, combined with the pivot pin, allows for flexible and smooth opening and closing of the sunroof. Its locking holes and grooves enable rapid and precise assembly with the damping buffer components, significantly improving production efficiency.

[0015] In the damping buffer, the cooperation between the housing guide rail and the damping strip guide rail groove effectively buffers the impact force when the sunroof closes. Combined with the flexible adjustment of the damping stroke by the limit bolts, it can adapt to sunroofs of different weights, extending the service life of the mechanism. The return spring ensures that the sunroof automatically resets after opening, and the combination of spring and spring sheet in the snap-fit ​​component facilitates the maintenance and replacement of the damping system. In addition, the stainless steel hinge arm is corrosion-resistant, the plastic spring sheet and rubber damping strip are wear-resistant and noise-reducing, and the multi-bolt hole design of the base plate enhances the structural adaptability, allowing the mechanism to operate stably in various environments.

The hinge seat 102 is plate-shaped and is mounted on the wall with screws, achieving stable installation and facilitating disassembly and maintenance. The hinge arm 103 is a hollow cuboid structure with a pin hole 104 at one end, connected to the hinge cup via a pin 105, and connected to the hinge seat with screws. The hinge arm has a snap-fit ​​hole 106 on the opposite side of the hinge seat, with a snap-fit ​​groove structure 107 inside the snap-fit ​​hole, providing a flexible rotation fulcrum to ensure smooth and unobstructed opening and closing of the sunroof and facilitating quick positioning and connection with the damping system. The damping buffer includes a housing 108 and a damping strip 109. The housing 108 is a hollow cuboid structure with a through hole on one side and a snap-fit ​​component on the other side. The damping strip 109 is a cuboid structure and is connected to the hinge arm through the snap-fit ​​component to achieve buffering damping, reduce the impact force when the sunroof is closed, and extend its service life.

[0028] In one possible implementation, a guide rail 201 is provided inside the housing, and a guide rail groove 202 matching the guide rail is provided on the damping strip. The damping strip is slidably disposed inside the housing, and the damping stroke can be adjusted to adapt to the buffering needs of sunroofs of different weights.

One end of the spring 301 is connected to the snap-fit ​​component, and the other end of the spring 301 is connected to the spring plate. The spring plate 302 is slidably disposed at the bottom of the snap-fit ​​component. This enables a detachable connection between the damping system and the hinge arm, facilitating future maintenance and component replacement.

[0031] In one possible implementation, a bolt hole 401 is provided on the damping strip 109, and a limiting bolt 402 is provided on the bolt hole to adjust the damping stroke and adapt to the buffering needs of sunroofs of different weights.
