[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] As shown in FIG. 1 and FIG. 2 , in one embodiment, a suspension mechanism 10 is provided, comprising a mounting body 100 and a locking structure 200. The mounting body 100 is provided with a first mounting hole 110, and the inner side wall of the first mounting hole 110 is provided with a locking portion 120. The locking structure 200 comprises a mounting assembly 210, a locking member 220 and an elastic member 230. The locking member 220 is coupled to the mounting assembly 210 and is located together in the first mounting hole 110, and the elastic member 230 is installed in the mounting assembly 210 and connected to the locking member 220. The elastic member 230 is used to apply an elastic force to the locking member 220 to move toward the inner side wall of the first mounting hole 110, so that the locking member 220 can be locked with the locking portion 120. When the locking portion 120 and the locking member 220 move relative to each other, the locking portion 120 can drive the locking member 220 to move in a direction away from the inner side wall of the first mounting hole 110 , so as to achieve unlocking and cooperation between the locking portion 120 and the locking member 220 .

[0030] When the hovering mechanism 10 in the above embodiment is used, the mounting body 100 is driven to rotate relative to the mounting assembly 210, so that the locking portion 120 on the inner side wall of the first mounting hole 110 rotates to the locking member 220, and the locking member 220 is locked and matched with the locking portion 120 under the action of the elastic member 230, so as to achieve the hovering effect. When the hovering needs to be released, the mounting body 100 is driven in the reverse direction to rotate relative to the mounting assembly 210, and the mounting body 100 squeezes the elastic member 230 through the locking portion 120 and the locking member 220, and the locking member 220 moves in the direction away from the inner side wall of the first mounting hole 110, so as to ensure that the locking member 220 can be separated from the locking portion 120, and the locking cooperation between the locking member 220 and the locking portion 120 is released, and the mounting body 100 can rotate again relative to the mounting assembly 210, thereby improving the practicality and experience of the hovering mechanism 10.

[0031] Among them, the mounting body 100 can be a mounting plate, a mounting block or other mounting structure. The locking portion 120 can be set as a hemispherical groove, an arc groove, a locking socket or other structure. The locking member 220 can be set as a lock tongue, a lock rod or other structure. The elastic member 230 can be set as a spring, an elastic telescopic column or other elastic structure. Specifically in this embodiment, the hovering mechanism 10 is applied to a fan structure. The locking member 220 is set as a wedge-shaped plastic structure. The first mounting hole 110 is a circular hole. In other embodiments, the first mounting hole 110 can also be an elliptical hole or a hole of other shapes.

[0032] The locking member 220 is coupled to the mounting assembly 210, and the locking member 220 and the mounting assembly 210 can be moved and matched along the radial direction of the first mounting hole 110, or can be moved and matched along the inclined direction. The inclined direction refers to the direction in which the radial direction of the first mounting hole 110 is inclined toward the axial direction of the first mounting hole 110.

[0033] As shown in FIG. 1 and FIG. 2 , further, the locking portion 120 is configured as a locking groove 121, and there is at least one locking groove 121, each locking groove 121 is configured on the inner side wall of the first mounting hole 110 along the circumference of the first mounting hole 110, and the locking member 220 can slide into or out of any one of the locking grooves 121 along the circumference of the first mounting hole 110. In this way, the locking member 220 can lock and cooperate with the locking groove 121 at any position, and the mounting body 100 can hover at multiple angles relative to the mounting assembly 210, meeting the user's needs for different hovering angles, and improving the practicality and experience of the hovering mechanism 10.

[0034] As shown in Fig. 2, optionally, the mounting body 100 is configured as an internal gear, and the locking groove 121 is a tooth groove of the internal gear. In this way, the mounting body 100 can hover at any angle relative to the mounting assembly 210, thereby improving the practicality and experience of the hovering mechanism 10.

[0035] As shown in FIG. 1 and FIG. 2 , in one embodiment, the mounting assembly 210 includes a hinge shaft 211 and a mounting shell 212. The mounting shell 212 is mounted on one end of the hinge shaft 211. The mounting shell 212 is provided with a mounting cavity 213. The outer wall of the mounting cavity 213 is provided with a connecting hole. The connecting hole extends along the radial direction of the first mounting hole 110 and communicates with the mounting cavity 213. The locking member 220 is penetrated through the connecting hole and slidably cooperates with the inner wall of the connecting hole. The elastic member 230 is installed in the mounting cavity 213 and connected with the locking member 220. In this way, the mounting shell 212 can guide the locking member 220, ensuring that the locking member 220 can extend into the locking groove 121 and press against the bottom wall of the locking groove 121, thereby ensuring that the hovering mechanism 10 can maintain the corresponding angle of hovering when not subjected to external force, thereby improving the reliability of the hovering mechanism 10.

[0036] Among them, the hinge shaft 211 and the mounting shell 212 can be integrally formed, or they can be separately formed and then assembled into one. The axis of the hinge shaft 211 can be located on the same straight line as the axis of the first mounting hole 110, or it can be located on a different straight line from the axis of the first mounting hole 110. Specifically in this embodiment, the mounting shell 212 can be fixed to one end of the hinge shaft 211 by snapping, plugging, screwing or other connection methods. The hinge shaft 211 is coaxially arranged with the first mounting hole 110. The mounting shell 212 is located in the first mounting hole 110 and is spaced apart from the inner side wall of the first mounting hole 110. The hinge shaft 211 is at least partially located outside the first mounting hole 110.

[0037] The number of the locking members 220, the connecting holes and the elastic members 230 can be flexibly adjusted according to the actual use requirements. For example, there are at least two connecting holes, each of which is respectively arranged on a different outer side wall of the mounting shell 212, the number of the locking members 220 is the same as the number of the connecting holes, each of the locking members 220 is arranged corresponding to each of the connecting holes, each of the locking members 220 is arranged at intervals, and one end of each of the locking members 220 located in the mounting cavity 213 is connected to the elastic member 230.

[0038] As shown in FIG. 1 and FIG. 2, further, there are at least two locking grooves 121, and the locking grooves 121 on both sides of the inner side wall of the first mounting hole 110 are symmetrically arranged about the axis of the first mounting hole 110. There are two connecting holes and locking members 220, and the two connecting holes are respectively located on the two opposite outer side walls of the mounting shell 212, and the axes of the two connecting holes are located on the same straight line. The two locking members 220 are arranged corresponding to the two connecting holes, and the two locking members 220 are arranged at intervals and are respectively connected to the two ends of the elastic member 230. In this way, by increasing the number of locking members 220, the limiting force between the mounting body 100 and the locking members 220 is increased, ensuring that the hovering mechanism 10 can stably and reliably maintain the corresponding angle of hovering when not subjected to external force, thereby improving the reliability of the hovering mechanism 10.

[0039] The two locking members 220 are respectively connected to two ends of the elastic member 230 by means of snap connection, plug connection, sleeve connection or other connection methods.

[0040] As shown in Fig. 1 and Fig. 2, optionally, the ends of the two locking members 220 close to each other are each provided with a second mounting hole for connecting the elastic member 230. When the two ends of the elastic member 230 are respectively extended into the two second mounting holes, the elastic member 230 is in a compressed state. In this way, while facilitating the assembly of the hovering mechanism 10, the inner side wall of the second mounting hole can also guide the elastic member 230, ensuring that the elastic member 230 can expand and contract along the radial direction of the first mounting hole 110, thereby improving the reliability of the hovering mechanism 10.

[0041] As shown in FIG. 1 and FIG. 2 , in one embodiment, the outer wall of the locking member 220 is provided with a limiting portion 221, which is located in the installation cavity 213 and is used to limit the inner wall of the installation cavity 213. In this way, the limiting portion 221 can play a limiting role, ensuring that the locking member 220 will not fall off from the connecting hole, thereby improving the reliability of the hovering mechanism 10.

[0042] Specifically in this embodiment, the limiting portion 221 is configured as a limiting protrusion, and there are two limiting protrusions, which are respectively arranged on both sides of the locking member 220 along the circumference of the first mounting hole 110. In this way, the limiting force applied to the locking member 220 is more evenly distributed, ensuring that the locking member 220 can stably and reliably reciprocate along the radial direction of the first mounting hole 110, thereby improving the reliability of the hovering mechanism 10.

[0043] As shown in FIG. 1 and FIG. 2 , in one embodiment, a chamfer 222 is provided at one end of the inner side wall of the locking member 220 close to the first mounting hole 110, and the chamfer 222 is used to slide with the inner side wall of the locking groove 121. In this way, the chamfer 222 can play a role in buffering the transition, ensuring that the locking member 220 can slide into and out of the locking groove 121 smoothly, thereby improving the user experience of the hovering mechanism 10.

[0044] Specifically in this embodiment, along the circumference of the first mounting hole 110, one end of the locking member 220 close to the inner side wall of the first mounting hole 110 includes a first side wall, an end face, and a second side wall connected in sequence, the first side wall and the end face, and the end face and the second side wall are both arranged at an obtuse angle, and the connection between the first side wall and the end face, and the connection between the end face and the second side wall are both provided with an arc chamfer 222. The contour line of the first side wall and the contour shape of the second side wall are respectively adapted to the contour shapes of the inner side walls of the locking groove 121 on both sides of the circumference of the first mounting hole 110.

[0045] As shown in FIG. 2 and FIG. 3 , in one embodiment, the mounting assembly 210 further includes a mounting seat 214 and a reinforcing rib 215. The mounting seat 214 is mounted on one end of the hinge shaft 211 away from the mounting shell 212, and the reinforcing rib 215 is fixedly connected to the mounting seat 214 and the outer side wall of the hinge shaft 211. In this way, the mounting seat 214 and the reinforcing rib 215 can both enhance the strength of the hinge shaft 211 and improve the reliability of the hovering mechanism 10.

[0046] The number of the reinforcing ribs 215 can be flexibly adjusted according to actual use needs. Specifically in this embodiment, there are at least two reinforcing ribs 215, and each reinforcing rib 215 is arranged around the axis of the hinge shaft 211. The hinge shaft 211, the mounting seat 214 and the reinforcing ribs 215 are integrally formed.

[0047] In one embodiment, a refrigerator is provided, comprising a cabinet, a cabinet door and the suspension mechanism 10 of any of the above embodiments, wherein one of the mounting body 100 and the mounting assembly 210 is mounted on the cabinet, and the other is mounted on the cabinet door, so that the cabinet door can rotate relative to the cabinet to open or close the cabinet.

[0048] When the refrigerator in the above embodiment is used, when the user needs to open the refrigerator, an external force is applied to the door, and the mounting body 100 rotates relative to the mounting assembly 210, so that the locking portion 120 on the inner wall of the first mounting hole 110 rotates to the locking member 220, and the locking member 220 is locked with the locking portion 120 under the action of the elastic member 230, so that the door is open and suspended. When the user takes out items in the refrigerator, the door is not affected by external force, and the locking member 220 is locked with the locking portion 120, so that the door does not rotate relative to the cabinet, thereby overcoming the problem that the door will close automatically and improving the user experience. When the user needs to close the refrigerator, an external force is applied to the door in the reverse direction, and the mounting body 100 rotates in the reverse direction relative to the mounting assembly 210. The mounting body 100 squeezes the elastic member 230 through the locking portion 120 and the locking member 220, and the locking member 220 moves along the inner side wall direction away from the first mounting hole 110, ensuring that the locking member 220 can be separated from the locking portion 120. The locking cooperation between the locking member 220 and the locking portion 120 is released, ensuring that the door can close the cabinet smoothly, thereby improving the practicality and convenience of the refrigerator.

[0049] The suspension mechanism 10 can be applied to refrigerators, freezers, washing machines, cabinets, doors and windows, or other products. The present application is described by taking the application of the suspension mechanism 10 to a refrigerator as an example, which should not be construed as a limitation on the present application.

[0050] Specifically in this embodiment, the mounting body 100 can be fixed to the door by snapping, plugging, screwing or other connection methods. The mounting seat 214 can be fixed to the cabinet by snapping, plugging, screwing or other connection methods. The rotation axis of the door relative to the cabinet is located on the same straight line as the axis of the first mounting hole 110. In other embodiments, the cabinet and the door can be further rotatably connected by adding a hinge assembly.
