BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 Schematic diagram of a hinge device for a refrigerator in a specific embodiment of the present invention. DETAILED DESCRIPTION

[0018] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0019] In the description of the specific embodiments of the present invention, the directions or positional relationships indicated by terms such as "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, usually with reference to the refrigerator in normal use, and do not indicate that the indicated position or element must have a specific orientation.

[0020] Furthermore, it should be understood that although the terms first, second, etc. may be used to describe various elements or structures in this article, these described objects should not be limited by the above terms. The above terms are only used to distinguish these described objects from each other. For example, the first planar side may be referred to as the second planar side, and similarly, the second planar side may also be referred to as the first planar side, without departing from the scope of protection of the application.

[0021] The specific embodiment provided by the present invention discloses a refrigerator, which includes a box body and a door body connected to the box body, wherein the box body defines a storage space, and the door body can be operated to open or close at least a part of the storage space. The storage space may include a plurality of storage compartments, and the number and structure of the storage compartments can be configured according to different requirements. The storage compartments generally include a refrigerating compartment and a freezing compartment.

[0022] like Figure 1 As shown, the door body is rotatably arranged on the box body through a hinge device 10, so as to open or close the box body. The hinge device 10 includes a hinge plate 12 fixedly arranged on the box body, a hinge stopper 14 arranged on the door body, and a hinge shaft 16. Among them, the hinge plate 12 and the hinge stopper 14 are rotatably connected through the hinge shaft 16. Further, the hinge plate 12 has a groove 18, and the hinge stopper 14 includes a fixed portion 20 fixedly connected to the door body, an end portion 22 spaced a certain distance from the fixed portion 20, and a connecting portion 24 connecting the fixed portion 20 and the end portion 22. The connecting portion 24 forms a certain angle with the fixed portion 20, and there is also a certain distance between the connecting portion 24 and the fixed portion 20, and the end portion 22 extends from the connecting portion 24 to the direction gradually approaching the fixed portion 20. When the door body is closed, the end portion 22 is located in the groove 18, so that the door body can be reliably closed. When the door is opened, the end 22 escapes from the groove 18. The hinge device 10 further includes a stopper 26 located between the fixing portion 20 and the end 22. The stopper 26 abuts against the fixing portion 20 and the end 22 to limit the end 22 of the hinge stopper 14 from deforming in the direction close to the fixing portion 20 and becoming ineffective. In this preferred embodiment, since there is a certain distance between the end 22, the connecting portion 24 and the fixing portion 20, the hinge stopper 14 has a certain deformation amount. When the door is closed, the end 22 can be pushed by the hinge plate 12 to deform a certain distance in the direction away from the fixing portion 20, so that the end 22 enters the groove 18. A stopper 26 is also provided between the fixing portion 20 and the end 22 to prevent the end 22 from deforming in the direction close to the fixing portion 20 after long-term use, so that the hinge stopper 14 and the hinge plate 12 maintain a relatively fixed interference. If the interference is too large, abnormal noise will be generated, thereby ensuring that the door can be reliably closed without abnormal noise.

[0023] In summary, in this preferred embodiment, since the stopper 26 is provided between the fixed portion 20 and the end portion 22, and the stopper 26 abuts against both the fixed portion 20 and the end portion 22, the hinge stopper 14 and the hinge plate 12 maintain a relatively fixed interference, thereby preventing the hinge stopper 14 from being deformed and failing after long-term door opening and closing operations. Moreover, only by providing the stopper 26, a certain interference can be maintained between the hinge stopper 14 and the hinge plate 12, which has a simple structure, a better door closing effect, avoids abnormal noise, and provides a better user experience.

[0024] Furthermore, the stopper 26 is fixedly arranged on the door body. Specifically, the door body includes a door frame and a door panel, the door frame includes an upper decorative strip, a lower decorative strip arranged opposite to the upper decorative strip, a left frame and a right frame connected to the upper decorative strip and the lower decorative strip and arranged opposite to each other, the upper decorative strip, the lower decorative strip, the left frame and the right frame form a closed square door frame, and the stopper 26 is integrally arranged on the upper decorative strip or the lower decorative strip. Thus, the structure is simple and easy to manufacture.

[0025] The stopper 26 is in sheet shape, and the extension direction of the stopper 26 is parallel to the extension direction of the fixing portion 20, and the thickness of the stopper 26 is 2 mm. Of course, the stopper 26 can also be set to other shapes, as long as the stopper 26 can abut against the fixing portion 20 and the end portion 22 respectively, so that a fixed distance is maintained between the fixing portion 20 and the end portion 22, thereby ensuring that a fixed interference is maintained between the hinge stopper 14 and the hinge plate 12.

[0026] The connecting portion 24 has a first curved side surface 28 connected to the end portion 22, a first plane side surface 30 directly connected to the first curved side surface 28, and a second arc side surface 32 directly connected to the first plane side surface 30 on the inner side facing the fixing portion 20. The fixing portion 20 includes a third arc side surface 34 circumscribed to the second arc side surface 32. The line connecting the center of the second arc side surface 32 and the center of the third arc side surface 34 is defined as the connecting center line. The second arc side surface 32 and the third arc side surface 34 are located on both sides of the connecting center line. After many experiments by the designers, such a setting not only eliminates abnormal noise when the door body is closed, but also closes reliably and provides a better user experience.

[0027] Specifically, the second arc side surface 32 is a semicircle, and the third arc side surface 34 is a quarter circle.

[0028] The hinge stopper 14 is fixedly connected to the door body by a first fastener (not shown) and a second fastener (not shown). Specifically, a first mounting hole 36 for mounting the first fastener and a second mounting hole 38 for mounting the second fastener are provided on the fixing portion 20, and a line connecting the center of the first mounting hole 36 and the center of the second mounting hole 38 is tangent to the second arc side surface 32. With such a configuration, the hinge stopper 14 is firmly installed, and when the door body is closed, under the push of the hinge plate 12, the end portion 22 and the connecting portion 24 will not be affected from deforming in a direction away from the fixing portion 20, so that the door is closed with less effort and the user experience is better.

[0029] In the preferred embodiment, the hinge plate 12 has a fourth arc side surface 40 defining a groove 18, a second plane side surface 42 connected to one end of the fourth arc side surface 40, a fifth arc side surface 44 directly connected to the other end of the fourth arc side surface 40, a third plane side surface 46 directly connected to the fifth arc side surface 44, and a sixth arc end surface 48 connected to the second plane side surface 42. When the door body is closed, the hinge stopper 14 rotates with the door body to allow the end 22 to enter the groove 18, and the sixth arc end surface 48 is arranged adjacent to the side where the end 22 enters. In this way, the hinge stopper 14 and the hinge plate 12 have a better fit, and the user has a better use experience, and the structure of the hinge stopper 14 and the hinge plate 12 is simpler. Further, the fifth arc side surface 44 is a 1 / 4 circle, and the third plane side surface 46 is tangent to the fifth arc side surface 44.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0031] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
