Description

Technical area

[0001] The utility model relates to the technical field of fittings and hinges, in particular to a damping hinge. Background technology

[0002] Hinges are commonly used in furniture, consisting of a concealed hinge and a connecting arm. The concealed hinge is attached to the door panel, and the connecting arm is mounted with a mounting seat fixed to the furniture frame. Among these, a hinge arm is installed at the junction between the concealed hinge and the connecting arm. The hinge arm is connected to a damper to ensure smooth opening and closing of the concealed hinge relative to the connecting arm. At the same time, it also has a damping effect to ensure the normal and stable use of furniture.

[0003] Currently, the damping cylinder of the general hinge is basically installed in the connecting arm, and the damping cylinder drives the hinge arm to rotate. The hinge arm is pivotally connected to the connecting arm. The hinge cup is driven to rotate by the rotation of the hinge arm to achieve the opening and closing of the hinge. In order to solve the problem that the hinge has both a height / distance adjustment structure and a damping structure, the applicant applied for a utility model patent with publication number CN117684836A on January 8, 2024.The structure is connected to the damping swing arm in the cavity. When the hinge arm is closed and rotated, the damping swing arm will abut against the cylinder block or the telescopic rod of the damper, so that the damping force of the damper indirectly acts on the hinge arm and the hinge to achieve the damping effect of the hinge. In the damping hinge structure, by installing the damper in the cavity of the cup hinge, it does not interfere with the complex manufacturing and installation structure inside the connecting arm, which reduces production requirements and costs. Also, due to the height and distance adjustment mechanism of the connecting arm, the damping performance does not affect. However, there are still some problems with this technical solution: I.In the actual manufacturing of the above-mentioned hinge, the damping swing arm, as the driving part, must be rotated to engage with the damper to achieve the damping effect. The installation accuracy requirements of the structure are high, and the installation is more difficult; II. When using the above-mentioned hinge, it does not have a mechanism for closing the damping effect, if it has a damping mechanism, but this damping effect is not deployed.

[0004] Therefore, it is necessary to further improve the hinge structure and technology. Content of the utility model

[0017] With reference to the Fig.1 to 6, a damping hinge is provided comprising a cup hinge 10 mounted on the door body and a connecting arm 20 mounted on the cabinet body, wherein a hinge arm 30 is provided between the cup hinge 10 and the connecting arm 20, wherein the hinge arm 30 serves to open and close the cup hinge 10 on the connecting arm 20, and the hinge arm 30 is received in the cavity 101 of the cup hinge 10 upon closing the hinge, which also includes a damping mechanism; more specifically, the hinge is further equipped with an elastic return mechanism (not shown in the figures) known in the art.In this embodiment, the elastic return mechanism adopts a torsion spring, and the torsion spring is mounted at a pivot point between the hinge arm 30 and the connecting arm 20; it should be understood that when the hinge is rotated to a preset angle for opening or closing, the elastic return mechanism provides the hinge with a return force to realize automatic opening and closing.

[0018] Specifically, based on the hinge described above, a damping mechanism 40 is also provided. The damping mechanism 40 includes a sliding member 41 and a damper 42 disposed in the sliding member 41. The sliding member 41 is movably disposed in the cavity 101; and the sliding member 41 can reciprocate within the cavity 101. When the door is opened by an external force, causing the hinge to reverse and close to the predetermined angle, the elastic return mechanism provides an acting force for the hinge arm 30 to automatically continue to reverse. Thus, the hinge arm 30 drives the sliding member 41 to move linearly into the cavity 101.In this process, the damper 42 of the jacking structure rests in the cavity 101, thereby triggering a damping action by the jacking structure, so that the damper 42 provides a damping force for the hinge to slow down the closing speed.

[0019] Specifically, a first side wall and a second side wall are provided opposite each other on both sides of the cavity 101. The first side wall and the second side wall are both chamfered to form a jacking structure; a jacking member 43 is provided between the jacking structure and the damper 42, and the jacking member 43 is movable along the chamfered surface of the jacking structure when the hinge is inverted to the predetermined angle to cause the jacking member 43 to press the damper 42 to provide the damping force for the hinge. Specifically, both ends of the damper 42 are equipped with the jacking member 43, and when the sliding member 41 slides in the cavity 101, the first side wall and the second side wall respectively press against the jacking member 43 at both ends of the damper 42, thereby triggering the damping effect.

[0020] In this embodiment, the sliding member 41 is provided with a through-hole that accommodates the damper 42 and the two jacking members 43. The two jacking members 43 are arranged at the two ends of the through-hole, and the jacking members 43 partially protrude from the through-hole to make contact with the jacking structure.

[0021] In this embodiment, the ends of the jacking member 43 are curved structures to make the movement of the jacking member 43 along the first side wall or the second side wall smoother.

[0022] In particular, the cavity 101 is also internally provided with a fairing cover 50, wherein the fairing cover 50 is provided on both sides with clamping blocks 501, wherein the cavity 101 is provided with a clamping slot 102 corresponding to the clamping block 501, wherein the clamping slot 102 is adapted to the clamping block 501, so that the fairing cover 50 is fixed in the cavity 101 when the clamping block 501 is adapted to the clamping slot 102; It is to be understood that the cowl cover 50 is also provided with a locking member 60, wherein a locking point 601 is provided on the locking member 60 and the cowl cover 50 is provided with a sliding groove 502, wherein the locking member 60 moves along the sliding groove 502 and the sliding member 41 is provided with a limiting groove 411 and a locking portion 412 is provided on the limiting groove 411.When the sliding element 41 is in a closed position, the locking point 601 movably cooperates with the locking portion 412. The hinge provided by this utility model has a damping effect; when it is not needed, the locking element 60 can be slid onto the trim cover 50 when the hinge is in the closed state, i.e., the locking point 601 of the locking element 60 is moved toward the locking portion 412 of the sliding element 41, so that the hinge arm 30 is unable to trigger the damping mechanism 40 when the hinge is reversed and closed, thus providing a mechanism that can disable the damping effect for the user.

[0023] In particular, the cavity 101 is provided with an elastic element 70, one end of which acts on the cup hinge 10 and the other end on the sliding element 41, so that when the hinge is turned over and opened, the elastic element 70 moves the sliding element 41 to the starting position. More specifically, the elastic element 70 is a compression spring, and the sliding element 41 is provided with a positioning groove 413. A positioning column 103 is provided at the rear of the cavity 101, one end of which is inserted into the positioning groove 413 and the other end is placed on the positioning column 103.when the hinge is reversed, the compression spring pushes the sliding element 41 to quickly reset it, so as to avoid that the sliding element 41 is not completely reset and the damping effect is reduced or even no damping effect is achieved by the personnel in case of rapid secondary closing of the door body.;

[0024] Although embodiments of the utility model have been illustrated and described, those skilled in the art will understand that numerous variations, modifications, substitutions, and alterations of these embodiments are possible without departing from the principle and spirit of the utility model, the scope of which is limited by the appended claims and their equivalents.
