Abstract

The present invention discloses a new two-stage power hinge comprising a hinge arm, a damping member, and a control unit pivoting to the hinge arm and used to modify the extension and retraction working stroke of the damping member, wherein the damping member comprises a damping fixed seat, a damping cover slidably connected to the damping fixed seat, and a damping device fixedly inserted into the damping fixed seat, wherein the extension end of the damping device faces the damping cover, and the extension end and the tail of the inner chamber of the damping cover are in contact with each other; wherein a support unit is installed on the hinge arm and mutually supported and coupled with the damping fixed seat, and the support unit is used to provide a supporting force to the damping fixed member and the control unit in the direction of the rotation axis of the control unit, effectively eliminating the risk of press-fitting and detachment inside the control unit and ensuring the normal helical rotation control function of the control unit, thereby providing better reliability and stability.

Description

New Type Two-Level Power Hinge The present invention belongs to the technical field of hinges, and in particular relates to a new type of two-stage power hinge. Hinges are widely used in the furniture industry, and types of hinges include single-stage, two-stage, and three-stage power hinges. The actual application areas for hinges are very wide, and different mounting situations result in varying cushioning requirements. Conventional hinge products are difficult to adjust effectively according to actual situations, leading to certain limitations and significantly reducing the universality of hinge products. To solve the above problem, the applicant has proposed a type of damping-adjustable two-stage power hinge in Chinese Patent CN110541639A. By changing the spiral rotation of the adjustment unit and the extension stroke of the damping member, it is advantageous during hinge closing operation and has cushioning angles of varying sizes. However, the spiral rotation operation of the conventional adjustment unit is generally performed by the user pressing it into the cross groove of the adjustment unit's cross section using a screwdriver. At this time, if the user applies high pressure to the adjustment unit, the adjustment unit may press against the damping fixing sheet, causing the adjustment unit to sink, and even abnormal phenomena such as detachment from the press may occur, making it difficult to change the expansion/extension stroke of the damping member again and causing hinge failure. Figure 1 is an assembly diagram of a hinge of an embodiment. Figure 2 is an exploded view of the hinge of the embodiment. Figure 3 is a cross-sectional view of the hinge arm of the embodiment. Figure 4 is a drawing of a damping member of an embodiment. FIG. 5 is a drawing of the internal vibration rod and the first joint of the embodiment. Figure 6 is a drawing of the control unit of the embodiment. To better understand the present invention, a comprehensive description thereof is provided below with reference to the drawings. The drawings present a relatively preferred embodiment of the present invention. However, the present invention can be achieved in various fixed forms and is not limited to the embodiment described in the text. The purpose of providing such an embodiment is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention. It should be noted that in the present invention, "first" and "second" do not indicate specific quantities or sequences, and are used solely for distinguishing names. Referring to FIGS. 1 through 6, in this embodiment, a novel two-stage power hinge comprises a hinge arm (1), a damping member (2), a control unit (5) pivoted to the hinge arm (1) and used to modify the extensional working stroke of the damping member (2), an internal vibration rod (3) pivoted to the front end of the hinge arm (1) via a second rotation axis (14), and a torsion spring (4) sleeved to a first rotation axis (13) installed at the front end of the hinge arm (1), wherein the damping member (2) comprises a damping fixed seat (24), a damping cover (21) orientedly slidingly connected to the damping fixed seat (24), and a damping device (22) fixedly embedded in the damping fixed seat (24), and specifically, an internal chamber used to accommodate a cylinder of the damping device (22) is formed in the damping fixed seat (24), and the damping fixed An opening extended to the front end is formed in the inner chamber of the sheet (24), thereby allowing the damping device (22) cylinder to be inserted into the inner chamber from the opening point at the front end of the damping fixed sheet (24), and the extension end of the damping device (22) faces the damping cover (21). Next, a mounting sliding groove (241) is formed in the damping fixed sheet (24) to be mutually slidingly connected with the damping cover (21). Specifically, the damping cover (21) of this embodiment has a U-shaped structure, and the damping cover (21) performs a directional sliding motion inside the mounting sliding groove (241), and the extension end of the damping device (22) and the rear part of the inner chamber of the damping cover (21) come into contact with each other. In this embodiment, both ends of the damping fixing sheet (24) are first fixed inside the hinge arm (1), and specifically, a positioning module (12) that mutually contacts the front end of the damping fixing member (24) is symmetrically formed on both inner walls of the hinge arm (1). Next, the damping fixing sheet (24) is further joined to the second rotation axis (14), and the positioning module (12) and the second rotation axis (14) together perform a contact position limiting action in the front-rear direction with respect to the damping fixing sheet (24).
