[0033] The principle and structure of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] Embodiment

[0035] As Figure 1 , 2As shown in FIGS. 3 and 4, the hinge structure includes a first component and a second component that rotate relative to each other about a rotating shaft 11. The first component includes an arc-shaped track 1 centered on the rotating shaft 11. The second component includes a slider 2. A guiding column 3 that slidably cooperates with the arc-shaped track 1 is provided on the slider 2, such that the slider 2 can slide along the arc-shaped track 1 or rotate about the guiding column 3 as the rotating shaft 11. A clamping head 18 is provided on the slider 2, and a clamping position for clamping the clamping head 18 is provided on the arc-shaped track 1. A retaining plate 5 groove 4 is provided on the slider 2. The first component includes a retaining plate 5 located in the retaining plate 5 groove 4 that can drive the slider 2 to move along the arc-shaped track 1. When the retaining plate 5 moves towards the clamping position, the clamping head 18 can be sent into the clamping position. When the retaining plate 5 moves away from the clamping position, the clamping head 18 can be disengaged from the clamping position.

[0036] The technical effect of adopting the above design is that: through the relative rotation of the first component and the second component, the clamping head 18 is fixed or disengaged from the clamping position, thereby realizing hovering at a specific position during rotation, which is convenient to control and does not affect other rotation functions of the rotating hinge.

[0037] An elastic resetting member is connected between the slider 2 and the first component. After the clamping head 18 is disengaged from the clamping position, the elastic resetting member resets the slider 2. The elastic resetting member is a cylindrical reset spring 6.

[0038] The technical effect of adopting the above design is that: after the clamping head 18 is disengaged from the clamping position by the elastic resetting member, the slider 2 can be reset, that is, the hinge structure becomes an automatically resetting hinge structure, and thus can be applied to devices such as doors that need to be automatically closed.

[0039] The clamping position is a radial clamping groove 7 located at the end of the arc-shaped track 1. The clamping head 18 is a sliding column that slidably cooperates with the arc-shaped track 1. The sliding column is located between the clamping groove and the guiding column 3.

[0040] The technical effect of adopting the above design is that: when the sliding column moves to the end of the arc-shaped track 1, under the guiding action of the end, the sliding column will be guided into the clamping groove, so that the sliding column is clamped in the clamping groove, thus realizing the temporary fixation of the slider 2 relative to the arc-shaped track 1. When the retaining plate 5 moves in the opposite direction, the retaining plate 5 pushes the retaining plate 5 groove 4 to make the slider 2 rotate by an angle about the guiding column 3, so that the sliding column comes out of the clamping groove and enters the arc-shaped track 1. At this time, the elastic resetting member can make the slider 2 slide along the arc-shaped track 1 to reset.

[0041] The notch of the groove 4 of the retaining piece 5 faces radially outward. When the chuck 18 slides into the card slot, the notch on one side of the groove 4 of the retaining piece 5 moves radially inward, enabling the retaining piece 5 to move out of the groove 4 of the retaining piece 5.

[0042] The technical effect of adopting the above design is that the retaining piece 5 can move out of the groove 4 of the retaining piece 5, so that the second component can continue to rotate relative to the first component without being affected by the blocking of the slider 2. When the slider 2 needs to be reset, the retaining piece 5 can be rotated in the reverse direction and return to the groove 4 of the retaining piece 5. Then, by pushing the groove 4 of the retaining piece 5, the slider 2 can be rotated around the guiding column 3 by an angle, so that the sliding column comes out of the card slot and enters the arc track 1. At this time, the elastic resetting member can make the slider 2 slide and reset along the arc track 1.

[0043] A guiding groove 8 that slidably cooperates with the retaining piece 5 is provided on the first component.

[0044] The technical effect of adopting the above design is that the guiding groove 8 provides guidance for the rotation of the retaining piece 5, enabling the retaining piece 5 to have a stable rotation path, and the moving range of the retaining piece 5 can be limited by setting the length of the guiding groove 8.

[0045] The first component includes a housing 9. The arc track 1 and the guiding groove 8 are located on the end face of the housing 9, and the slider 2 is located inside the housing 9. The housing 9 is the end of a cylindrical housing 9. The guiding groove 8 is a through groove opened on the housing 9. The retaining piece 5 movably passes through the through groove and is connected to a device outside the housing 9. The other end of the housing 9 is connected to a plate body 10. A rotating shaft 11 passing through the cylindrical housing 9 is provided on the plate body 10. A fitting hole 12 for the rotating shaft 11 to pass through is provided in the middle of the housing 9 and the rotating shaft 11, so that the rotating shaft 11 and the fitting hole 12 can slide axially but cannot rotate relative to each other.

[0046] The technical effect of adopting the above design is that the slider 2 rotates inside the housing 9. The housing 9 is equivalent to a chamber for the slider 2 to move, which can limit the stable rotation of the slider 2 along the annular track and is also beneficial for protecting components such as the return spring 6 of the slider 2.

[0047] As Figure 8 、 9 As shown in Figures 10, 11, and 12, the hinge structure is applied to a hovering door.

[0048] The technical effect of adopting the above design is that applying the hinge structure to a hovering door enables the door to be conveniently hovered at a specific position only by rotating the door.

[0049] The first component is fixed on the door frame 13, and the second component is fixed on the door body 14. In this embodiment, the plate body 10 is connected to the door frame 13 by bolts 15, the retaining piece 5 is connected to the door body 14, and the hinge axis of the door body 14 is coaxial with the rotating shaft 11. A positioning hole for the rotating shaft 11 that rotates in cooperation with the rotating shaft 11 is provided on the door body 14.

[0050] The technical effect of adopting the above design is that when the door body 14 rotates, it drives the retaining piece 5 to rotate, thereby driving the slider 2 in the housing 9 to rotate. Through the temporary locking of the locking head 18 on the slider 2 with the card slot of the annular track, the door body 14 is suspended relative to the door frame 13.

[0051] The radian of the arc track is greater than or equal to 90 degrees, so that when the first component rotates relative to the second component by more than or equal to 90 degrees, the locking head is locked to the locking position.

[0052] The technical effect of adopting the above design is that when the first component rotates relative to the second component by more than or equal to 90 degrees, the locking head is locked to the locking position, so that the door body can be suspended only after it is opened by 90 degrees, which is convenient for the door body to be suspended after being fully opened.

[0053] If the first component rotates relative to the second component by 90 degrees and the locking head is locked to the locking position, then when the door is opened to 90°, it can continue to be opened. At this time, the return spring is no longer stretched, and the stopper does not rotate with the door body anymore. When the user opens the door to more than 90° and releases it, if the door rebounds, it will be blocked by the stopper to the 90° door opening state, that is, when the user closes the door, as long as the door body is closed to less than 90°, the door body will slowly close and reset under the action of the return spring.

[0054] As Figure 5 、 6 、shown in FIG. 7, the hovering door is applied to the refrigerator 17.

[0055] The technical effect of adopting the above design is that by installing a stopper on the hinge, the refrigerator door body drives the stopper to rotate to the hovering point during the opening process, so that when the refrigerator door body rebounds to the hovering point, it is blocked. During the opening process, the door body drives the stopper to rotate to the hovering point, and the stopper at the limiting point will prevent the door body from rebounding after the opening is completed. When the user opens the door to more than 90° to take items from the refrigerator, under the action of the stopper, the door body will only rebound to 90°, which will not affect the user's taking of items.

[0056] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0057] Although some terms are used more frequently herein, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model. For the execution order of actions, steps, etc. in the devices and methods shown in the specification and drawings, as long as there is no specific explicit order limitation and the output of the previous process is not used in the subsequent process, they can be implemented in any order. Similar sequential terms (such as "first", "then", "secondly", "again", "then", etc.) used for convenience of description do not mean that they must be implemented in such an order.

[0058] Those of ordinary skill in the art should understand that all directional references (such as above, below, upward, up, downward, down, top, bottom, left, right, vertical, horizontal, etc.) are descriptively used in the drawings to assist the reader's understanding and do not represent (such as for position, orientation, or use, etc.) a limitation on the scope of the present utility model defined by the appended claims. It is only for the convenience of describing the present application and simplifying the description. Without contrary indication, these directional terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. The directional terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0059] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above-mentioned", etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0060] In addition, some ambiguous terms (e.g., substantially, certain, generally, etc.) may refer to slight inaccuracies or slight deviations in conditions, quantities, values, dimensions, etc., some of which are within the manufacturing deviations or tolerances. It should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above terms have no special meaning, and thus cannot be construed as a limitation on the scope of protection of this application.
