Single adjustment function: the mainstream products on the market such as German hinge have damping adjustment function, but only can adjust the overall pressure value, cannot dynamically adjust the angle of damping effect for different working conditions. When applied to the super heavy door plate, the damping effect triggered too early (such as 45 degrees) will cause insufficient closing power; and for light door plate, the damping intervention too late (such as 15 degrees) will produce impact noise. This contradiction seriously limits the application range of the product.

DETAILED DESCRIPTION

[0030] To make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0031] The utility model will be described in further detail in combination with the drawings as follows:

[0032] As Figures 1 to 4 shown, according to the utility model provides a kind of embedded hidden door hinge, including: fixed plate assembly 1, door plate assembly 2, torsion spring 3, damper assembly and transmission assembly;

[0033] Fixed plate assembly 1 is installed in the groove in the fixed side and is decorated with fixed plate decorative cover 11, and door plate assembly 2 is installed in the groove in the door plate and is decorated with door plate decorative cover 24;

[0034] The spring body 31 of torsion spring 3 is fixed on the first transmission piece 21 of door plate assembly 2, and the two sides torsion arm 32 of torsion spring 3 are respectively clamped between the second transmission piece 22 of door plate assembly 2 and the clamping groove connecting part 141 of fixed plate assembly 1, and fixed plate assembly 1 and door plate assembly 2 are connected by the second transmission piece 22;

[0035] The damper assembly is installed inside the fixed plate assembly 1. The damper assembly includes a damper 41 and a damping movable plate 42. The damping movable plate 42 is installed at the end of the damper 41. The damping movable plate 42 adopts an eccentric wheel structure. Rotating the damping movable plate 42 can compress the piston end of the damper 41, thereby adjusting the transmission distance between the damper 41 and the second transmission plate 22. This allows the second transmission plate 22 to trigger the damper 41 when rotating to different angles during the closing process, so as to achieve damping buffer when the door panel is closed to different angles.

[0036] In this embodiment, the eccentric wheel structure of the damping movable piece 42 in the damper assembly enables the adjustable function of triggering damping buffer when the door is closed at different angles. This effectively solves the problem of noise when closing the door when the door panel is not large, and also solves the problem of hand pinching caused by insufficient damping buffer when the door panel is closed at a small angle. Combined with the torsion spring 3, it can effectively improve the smoothness of opening and closing the door panel and increase the service life of the hinge. In addition, the recessed installation method of the fixing plate assembly 1 and the door panel assembly 2 achieves the concealment effect of the hinge.

[0037] Specifically, during the implementation process, when the door is closed, the door panel begins to rotate under the trigger of the force. During the rotation, the torsional force of the torsion spring 3 is overcome. At the same time, the torsional force of the torsion spring 3 provides damping buffer for the closing of the door panel. When the door is rotated to a predetermined angle, the damper 41 is triggered. The damper 41 provides further damping buffer for the closing process of the door panel, so that the door panel can close slowly.

[0038] In the above embodiment, preferably, the rotation of the damping movable piece 42 can adjust the compression displacement of the damper 41, so that the angle of the trigger damper 41 can be adjusted between 20° and 40° during the door closing process.

[0039] During implementation, the damper 41 can be adjusted to the required compression displacement by rotating the damping movable plate 42, thereby adjusting the angle at which the damper 41 is triggered during the door closing process. Through pre-designed structure and specifications, the compression displacement generated by the rotation of the damping movable plate 42 allows the trigger angle of the damper 41 during door closing to be adjusted between 20° and 40°.

During the opening process of the door panel assembly 2 relative to the fixed plate assembly 1, the two torsion arms 32 can provide assistance for the opening process.

[0041] In the above embodiment, preferably, the fixed plate assembly 1 further comprises a fixed plate fixing seat 12, a movable support 13 and a fixed support 14;
