Description

Technical Field

[0001] This utility model relates to the field of hardware accessories technology, specifically to a hinge and a hinge drive structure. Background Technology

[0002] Hinges are a key component of furniture cabinet doors, and their performance directly affects the lifespan of the furniture and the user experience. To improve the quality of use, modern hinges generally integrate dampers to provide a soft, quiet closing effect during closure.

[0003] In some common solutions in the prior art, the piston rod of the damper is directly in contact with the drive arm of the hinge. The rotation of the drive arm directly pushes the piston rod to make the damper work. However, this driving method is always subject to the force of the damper during the opening or closing of the hinge, which causes the cabinet door to experience great resistance throughout the entire movement, making it difficult to open and close, resulting in a poor user experience. Other solutions use linkages, gears, etc. to drive the piston rod, but their structure is complex, resulting in a large overall size and high cost of the hinge. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hinge and a hinge driving structure to reduce the hinge size while improving the user experience.

[0005] In a first aspect, the hinge drive structure provided by this utility model includes: a hinge cup and a hinge arm; A sliding plate is provided inside the hinge cup, and the hinge arm includes a drive rod and a drive block. The drive rod is connected to the drive block, and the drive block is hinged to the hinge cup. The drive block has a notch, and the two side walls of the notch along the circumferential direction are the first drive wall and the second drive wall, respectively. The sliding plate has a baffle that extends into the notch. The rotation of the drive block can cause the first drive wall or the second drive wall to contact the baffle.

[0006] Furthermore, the angle between the first driving wall and the second driving wall in the circumferential direction is 60°~120°.

[0007] Furthermore, the drive block includes a first drive plate and a second drive plate, a first drive wall is disposed on the first drive plate, a second drive wall is disposed on the second drive plate, the first drive plate is an arc-shaped plate, and the first drive plate is hinged to the hinge cup.

[0008] Furthermore, the drive block and drive rod are detachably connected, and the drive block and drive rod are made of different materials.

[0009] Furthermore, one of the drive rod and the drive block is provided with a snap-fit ​​groove, and the other is provided with a snap-fit ​​block. The snap-fit ​​block is inserted into the snap-fit ​​groove to connect the drive rod and the drive block.

[0010] Furthermore, the drive rod is provided with two lugs, which are located on both sides of the drive block. Both lugs are provided with connecting holes, through which the hinge shaft of the drive block and the hinge cup passes to achieve the hinge connection between the drive rod and the damper mounting base.

[0011] Furthermore, the notch in the drive block extends through the drive block along the axial direction of the hinge axis.

[0012] Furthermore, the first and second driving walls transition with the adjacent wall surfaces using circular arcs.

[0013] Furthermore, the baffle and the sliding plate are integrally formed.

[0014] Secondly, this utility model provides a hinge, comprising a hinge drive structure as described above.

[0015] As can be seen from the above technical solution, the hinge drive structure provided by this utility model drives the sliding plate to slide through the cooperation of the first and second drive walls of the drive block notch on the hinge arm and the baffle of the sliding plate, thereby further driving the damper. When the drive block rotates at a certain angle, the first or second drive wall of the drive block contacts the baffle, so that the damper works at the end stage of the cabinet door closing, achieving the effect of lightness at the front and buffer at the rear when the cabinet door closes. The structure is simple and compact, and the damper is driven by the sliding of the sliding plate, which effectively reduces the overall volume of the hinge and reduces the manufacturing cost.

Detailed Implementation

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0020] like Figure 1-3 As shown, the hinge drive structure provided in this embodiment includes a hinge cup 1 and a hinge arm 2. A sliding plate 11 is provided inside the hinge cup 1. The hinge arm 2 includes a drive rod 21 and a drive block 22. The drive rod 21 is connected to the drive block 22, and the drive block 22 is hinged to the hinge cup 1. The drive block 22 has a notch 221. The two side walls of the notch 221 along the circumferential direction are the first drive wall 2221 and the second drive wall 2231, respectively. The sliding plate 11 is provided with a baffle 111 that extends into the notch 221. The rotation of the drive block 22 can make the first drive wall 2221 or the second drive wall 2231 contact the baffle 111.

[0021] Specifically, the sliding plate 11 is slidably disposed within the hinge cup 1, and one end of the sliding plate 11 is connected to the damper of the hinge. The baffle 111 of the sliding plate 11 extends into the notch 221 of the drive block 22. During the hinge closing process, the hinge arm 2 rotates, causing the drive block 22 to rotate about the hinge axis 3 between the hinge arm 2 and the hinge cup 1. In the initial stage of hinge closing, the first drive wall 2221 contacts the baffle 111. As the drive block 22 continues to rotate, the first drive wall 2221 separates from the baffle 111. At this time, the baffle 111 moves within the notch 221, and no force is generated between the drive block 22 and the sliding plate 11. Therefore, the damper does not generate resistance to this process. In the later stage of hinge closing, the second drive wall 2231 contacts the baffle 111 and drives the sliding plate 11 to slide through the baffle 111, thereby causing the damper to generate damping. This allows the damper to operate at the final stage of the cabinet door closing, achieving a smooth opening and a buffered closing effect. Furthermore, the damper is driven by the sliding plate 11, resulting in a simple and compact structure that effectively reduces the overall size of the hinge and lowers manufacturing costs.

[0022] Furthermore, the angle between the first drive wall 2221 and the second drive wall 2231 in the circumferential direction is 60°~120°. This angle range ensures that during the rotation of the hinge arm 2, the first drive wall 2221 and the second drive wall 2231 contact the baffle 111 at the appropriate time, thereby driving the sliding plate 11 to slide, and thus enabling the damper to work at the appropriate stage of the cabinet door opening and closing, achieving the effect of light movement in the front and buffering in the rear.

[0023] Furthermore, the drive block 22 includes a first drive plate 222 and a second drive plate 223. A first drive wall 2221 is disposed on the first drive plate 222, and a second drive wall 2231 is disposed on the second drive plate 223. The first drive plate 222 is an arc-shaped plate and is hinged to the hinge cup 1.

[0024] Specifically, the first drive plate 222 is an arc-shaped plate, which is located radially outside the hinge shaft 3, and the arc-shaped profile of the arc-shaped plate is coaxial with the hinge shaft 3. This arrangement allows the drive block 22 to move more smoothly during rotation.

[0025] Furthermore, the drive block 22 is detachably connected to the drive rod 21, and the drive block 22 and drive rod 21 are made of different materials. This detachable connection facilitates replacement of the drive block 22 when it wears out. The different materials of the drive block 22 and drive rod 21 also reduce contact noise between the drive block 22 and the baffle 111 during hinge closing, improving the user experience. For example, the drive rod 21 can be made of metal, and the drive block 22 can be made of non-metallic material.

[0026] Furthermore, one of the drive rod 21 and the drive block 22 is provided with a snap-fit ​​groove, and the other is provided with a snap-fit ​​block. The snap-fit ​​block is inserted into the snap-fit ​​groove to connect the drive rod 21 and the drive block 22. The drive rod 21 and the drive block 22 are connected by a snap-fit ​​mechanism, which is convenient for installation and facilitates production and subsequent maintenance.

[0027] It is understandable that the drive rod 21 and the drive block 22 can also be connected in other ways, such as by bolts.

[0028] Furthermore, the drive rod 21 is provided with two lugs 212, which are respectively located on both sides of the drive block 22. Each lug 212 is provided with a connecting hole, through which the hinge shaft 3 of the drive block 22 and the hinge cup 1 passes to achieve the hinge connection between the drive rod 21 and the damper mounting base. The lugs 212 enable the drive rod 21 and the drive block 22 to be coaxially hinged with the hinge cup 1, ensuring the rotational synchronization of the drive rod 21 and the drive block 22 and improving the overall durability of the hinge.

[0029] Furthermore, the notch 221 of the drive block 22 extends through the drive block 22 along the axial direction of the hinge shaft 3. That is, the notch 221 of the drive block 22 is a through groove extending through the axial direction of the hinge shaft 3. This design facilitates the insertion of the baffle 111 into the notch 221, avoiding assembly difficulties or stress concentration problems caused by non-through design. It also simplifies the processing technology of the drive block 22 and reduces manufacturing costs.

[0030] Furthermore, the first drive wall 2221 and the second drive wall 2231 transition with adjacent walls via arcs. Specifically, during the rotation of the hinge arm 2, the drive block 22 transitions from the end wall to the corresponding drive wall via an arc, ensuring a smooth transition and reducing impact during rotation. Setting the first drive wall 2221 and the second drive wall 2231 to adjacent walls via arcs reduces contact damage between the drive block 22 and the baffle 111, reduces impact and noise, and improves the overall durability of the hinge and the user experience.

[0031] Furthermore, the baffle 111 and the sliding plate 11 are integrally formed. Integrating the baffle 111 and the sliding plate 11 can reduce manufacturing costs while enhancing the structural strength of the sliding plate 11. For example, the baffle 111 can be formed by bending the sliding plate 11 toward the hinge arm 2.

[0032] For example, the hinge cup 1 is provided with a slide rail that can limit the sliding plate 11. The sliding plate 11 is slidably installed in the slide rail. Specifically, the hinge cup 1 includes a base plate and a mounting seat for mounting the damper. The slide rail can be formed by the base plate and the mounting seat, or it can be a sliding groove provided on the base plate. In the initial stage of hinge closure, the first drive wall 2221 contacts the baffle 111. In the later stage of hinge closure, the second drive wall 2231 contacts the baffle 111 and drives the sliding plate 11 to slide along the slide rail through the baffle 111, thereby causing the damper to generate damping.

[0033] like Figure 4 As shown, this utility model also provides a hinge, including the hinge drive structure provided in any of the above embodiments. The hinge arm 2 is hinged to the base 4, which is mounted on the cabinet body. The hinge cup 1 is mounted on the cabinet door. When the cabinet door is closed, the hinge arm 2 rotates with the cabinet door, contacting one end of the sliding plate 11 and pushing it to slide. The movement of the sliding plate 11 is transmitted to the damper, generating a buffering force. When the cabinet door is opened, the damper resets, driving the sliding plate 11 back to its initial position, preparing for the next closing.
