Abstract
Description
Technical Field
[0001] This utility model relates to the field of segmented round hinge technology, and in particular to a segmented round hinge. Background Technology
[0002] Currently, most mainstream rotary hinges on the market adopt a single-wrap structure design. In this type of hinge, the wrapping portion is an integral, unidirectional structure. Rotational torque is generated through the interaction between the wrapping and the pivot, thus achieving the opening and closing positioning function of the component. This single-wrap hinge structure is widely used in various products due to its simple structure and low manufacturing cost.
[0003] However, because the encircling part has a single direction, it cannot differentiate the torque in both directions, resulting in a significant difference in torque when the hinge is opened and closed, creating a distinct "light opening, heavy closing" feel. Specifically, the torque is low and the operation is easy when opening, while the torque increases dramatically and the operation is difficult when closing. This problem not only seriously affects the user experience, but also causes excessive torque when closing, which can easily lead to collisions and impacts at the opening and closing parts, accelerating wear on the hinge and product connection parts, and shortening the overall service life. Utility Model Content
[0004] Based on this, the present invention provides a segmented encircling hinge with a simple structure and convenient use. It has a first encircling circle and a second encircling circle with opposite bending directions. By moving the second working surface and the opening of the second encircling circle away from each other, the instantaneous torque of the hinge when it is opened is significantly increased. This significantly reduces the torque difference between the open and closed states of the hinge, which can not only meet the product's torque requirements, but also effectively balance the torque difference, thereby greatly optimizing the hinge's operating feel.
[0005] To achieve the objectives of this utility model, the following technical solution is adopted: A segmented, rounded hinge, comprising: The first support includes a first support body and a rotating shaft detachably connected to the first support body; the rotating shaft includes a bearing portion and a spindle connected to one end of the bearing portion; a clearance surface is provided on one side of the outer peripheral surface of the spindle along its axial direction; and A second bracket is rotatably connected to a first bracket; the second bracket includes a second bracket body, a support portion extending outward from one side of the second bracket body, a first enclosing circle connected to one end of the support portion, and a second enclosing circle connected to the other end of the support portion; the shaft is coaxially inserted through the first enclosing circle and the second enclosing circle in sequence, and the shaft and the first enclosing circle and the second enclosing circle are both interference fit; a first working surface is provided on the inner wall of the first enclosing circle near the opening of the first enclosing circle, and a second working surface is provided on the inner wall of the second enclosing circle away from the opening of the first enclosing circle, and the second working surface and the first working surface are coplanar; when closed, the first working surface and the second working surface are matched and fitted with the clearance surface; when opened, the shaft and the first enclosing circle and the second enclosing circle rotate relative to each other, and the corner on the clearance surface side is used to push open the first working surface and the second working surface.
[0006] The aforementioned segmented encircling hinge has a simple structure and is easy to use. It has a first encircling circle and a second encircling circle with opposite bending directions. By moving the second working surface and the opening of the second encircling circle away from each other, the instantaneous torque of the hinge when it is opened is significantly increased. This significantly reduces the torque difference between the open and closed states of the hinge, which can not only meet the product's torque requirements, but also effectively balance the torque difference, thereby greatly optimizing the hinge's operating feel.
[0007] In one embodiment, the first and second envelopes are spaced apart and coaxially arranged.
[0008] In one embodiment, the first round bends counterclockwise along the axis of the shaft, and the second round bends clockwise along the axis of the shaft.
[0009] In one embodiment, the width of the first working surface is equal to the width of the second working surface, and the length of the first working surface is greater than the length of the second working surface.
[0010] In one embodiment, the length of the first envelope is greater than the length of the second envelope.
[0011] In one embodiment, the first support body and the load-bearing part are fixedly connected by rivets. Attached Figure Description

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0017] Please see Figures 1 to 6 The segmented encircling hinge of this utility model includes a first bracket 10 and a second bracket 20 rotatably connected to the first bracket 10.
[0018] The first support 10 includes a first support body 11 and a rotating shaft 12 detachably connected to the first support body 11. The rotating shaft 12 includes a bearing portion 121 and a core 122 connected to one end of the bearing portion 121; the bearing portion 121 is used to connect the first support body 11, and the core 122 is used to connect the second support 20.
[0019] Specifically, such as Figure 3 As shown, a clearance surface 123 is provided on one side of the outer peripheral surface of the shaft 122 along its axial direction.
[0020] In this embodiment, as Figure 3 As shown, the first bracket body 11 and the bearing part 121 are fixedly connected by rivets 13.
[0021] The second support 20 includes a second support body 21, a support portion 22 extending outward from one side of the second support body 21, a first enclosing circle 23 connected to one end of the support portion 22, and a second enclosing circle 24 connected to the other end of the support portion 22; the shaft 122 is coaxially inserted through the first enclosing circle 23 and the second enclosing circle 24 in sequence to achieve a rotatable connection between the first support 10 and the second support 20. The shaft 122 is fitted with both the first enclosing circle 23 and the second enclosing circle 24 using an interference fit to ensure the supporting force between the first support 10 and the second support 20.
[0022] Specifically, the first enclosing circle 23 and the second enclosing circle 24 are spaced apart and coaxially arranged. The first enclosing circle 23 is bent in a counterclockwise direction along the axis of the axis 122, and the second enclosing circle 24 is bent in a clockwise direction along the axis of the axis 122. The bidirectional bending structure provides a basis for torque adjustment.
[0023] Furthermore, the first round 23 has a first working surface 230 on the inner wall of the side near its opening, and the second round 24 has a second working surface 240 on the inner wall of the side away from its opening. The second working surface 240 is coplanar with the first working surface 230.
[0024] In this embodiment, the width of the first working surface 230 is equal to the width of the second working surface 240, and the length of the first working surface 230 is greater than the length of the second working surface 240.
[0025] When closed, such as Figure 1 As shown, both the first working surface 230 and the second working surface 240 are precisely matched and tightly fitted with the clearance surface 123, ensuring stability in the closed state. When opened, the attached... Figure 6 As shown, the axis 122 rotates relative to the first enclosing circle 23 and the second enclosing circle 24, and the corner on one side of the clearance surface 123 is used to open the first working surface 230 and the second working surface 240.
[0026] In simple terms, in traditional unidirectional enclosing hinges, the working surface is close to the opening of the enclosing circle. When the hinge is opened and subjected to force, the elastic deformation at the opening can respond quickly (the opening opens easily), resulting in low initial resistance. However, in this invention, the second working surface 240 is far from the opening of the second enclosing circle 24, causing a delay in its axial expansion. Therefore, when the shaft 122 rotates, the corner on the side of the clearance surface 123 opens the first working surface 230 first (responding quickly because the first working surface 230 is close to the opening of the first enclosing circle 23), while the second enclosing circle 24, because its opening is far from the second working surface 230, cannot release the clamping force in time by opening its opening, thus producing an instantaneous damping enhancement effect.
[0027] In other words, in the initial stage of hinge opening, the clamping force of the second enclosing circle 24 on the axis 122 fails to weaken in time due to the delayed axial expansion of the second enclosing circle 24. This is equivalent to adding "clamping damping" to the first enclosing circle 23 (normal response, low resistance), and the combined effect of the two significantly increases the instantaneous torque of the hinge opening. As rotation continues, the elastic deformation of the second enclosing circle 24 gradually accumulates, the opening slowly expands, the clamping force gradually weakens, the second enclosing circle 24 gradually completes its axial expansion, and the torque returns to a normal level, eventually becoming consistent with the resistance characteristics of a traditional single-enclosing hinge. Compared with traditional single-direction enclosing hinges, the segmented enclosing hinge of this invention maintains a basically unchanged torque in the closed state, while significantly increasing the instantaneous torque in the open state. This significantly reduces the torque difference between the open and closed states, meeting the product's torque requirements while effectively balancing torque differences, thereby greatly optimizing the hinge's operating feel.
[0028] In this embodiment, the length of the first enclosing circle 23 is greater than the length of the second enclosing circle 24.
[0029] The aforementioned segmented enclosing hinge has a simple structure and is easy to use. It has a first enclosing circle 23 and a second enclosing circle 24 with opposite bending directions. The openings of the second working surface 240 and the second enclosing circle 24 are far apart, which significantly increases the instantaneous torque when the hinge is opened. This significantly reduces the torque difference between the open and closed states of the hinge, which can not only meet the product's torque requirements, but also effectively balance the torque difference, thereby greatly optimizing the hinge's operating feel.
[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
