DETAILED DESCRIPTION

[0041] The following is a further detailed description of the implementation of the present application in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.

[0042] In the description of the embodiments of the present application, it should be noted that the terms "circumferential", "axial", "radial", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0043] In the description of this specification, the description with reference to the term "an embodiment" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment are included in at least one embodiment of the embodiments of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0044] In the related art, the hinge has multiple fixing holes, and the multiple fixing holes usually penetrate the hinge in the same direction, resulting in a relatively single direction of the tightening force applied by the screws on the hinge. When the screws in this direction are loose, the overall connection strength of the hinge will be affected.

[0045] In view of this, please refer to Figure 1 to Figure 5 The embodiment of the present application provides a hinge 1, including a first hinge seat 11 and a second hinge seat 12. The second hinge seat 12 includes a hinge seat body 121 and a first reinforcement member 122 that are connected to each other, the hinge seat body 121 is rotatably connected to the first hinge seat 11, the central axis of rotation of the first hinge seat 11 relative to the hinge seat body 121 is the target axis, the first reinforcement member 122 has a first fixing hole 122a, the hinge seat body 121 has a second fixing hole 121a, and the direction in which the first fixing hole 122a penetrates the first reinforcement member 122 is cross-arranged with the direction in which the second fixing hole 121a penetrates the hinge seat body 121.

[0046] In the embodiment of the present application, the direction in which the first fixing hole 122a penetrates the first reinforcement 122 intersects with the direction in which the second fixing hole 121a penetrates the hinge seat body 121, so that the screw can apply a tightening force to the second hinge seat 12 in two different directions. When the screw in one direction is loose, the screw can still constrain the movement of the second hinge seat 12 in the other direction, and the second hinge seat 12 can be fixed relatively firmly with the tightening force applied by the screw that is not loose in the other direction. Furthermore, when the screws in both directions are loose, the screws in the two directions are arranged crosswise, which can also provide the second hinge seat 12 with two different directions of restraining force, thereby fixing the second hinge seat 12 relatively stably, which is conducive to improving the connection strength of the hinge 1.

[0047] Exemplarily, the materials of the first hinge seat 11 and the second hinge seat 12 are not limited, and may be, for example, POM (Polyoxymethylene) material.

[0048] For example, see Figure 2 to Figure 4 The first reinforcement member 122 and the hinge seat body 121 are perpendicular to each other, and the direction in which the first fixing hole 122a penetrates the first reinforcement member 122 and the direction in which the second fixing hole 121a penetrates the hinge seat body 121 are also perpendicular to each other.

[0049] For example, see Figure 2 to Figure 4 The first fixing hole 122a penetrates the first reinforcement 122 in the up-down direction, the second fixing hole 121a penetrates the hinge seat body 121 in the left-right direction, the screw penetrates the first fixing hole 122a in the up-down direction, and applies a tightening force in the up-down direction to the second hinge seat 12, and the screw penetrates the second fixing hole 121a in the left-right direction, and applies a tightening force in the left-right direction to the second hinge seat 12. When the screw located in the first fixing hole 122a is loosened, the screw located in the first fixing hole 122a can still provide a restraining force in the left-right direction to the second hinge seat 12, and cooperate with the screw located in the second fixing hole 121a to fix the second hinge seat 12 more firmly. When the screw located in the first fixing hole 122a and the screw located in the second fixing hole 121a are both loose, the screw located in the first fixing hole 122a can provide a restraining force in the left-right direction to the second hinge seat 12, and the screw located in the second fixing hole 121a can provide a restraining force in the up-down direction to the second hinge seat 12. The restraining forces in two different directions can fix the second hinge seat 12 more stably, which is beneficial to improve the connection strength of the second hinge seat 12.

[0050] Exemplarily, the arrangement of the first hinge seat 11 and the second hinge seat 12 is not limited.

[0051] For example, see Figure 4 and Figure 5, the first hinge seat 11 and the second hinge seat 12 can be staggered along the target axis.

[0052] Exemplarily, a projection of the first hinge seat 11 along a direction in which the first fixing hole 122 a penetrates the first reinforcement member 122 may be within a range of a projection of the second hinge seat 12 along a direction in which the first fixing hole 122 a penetrates the first reinforcement member 122 .

[0053] Exemplarily, the first reinforcement member 122 and the hinge seat body 121 are formed in any manner.

[0054] Exemplarily, the first reinforcement member 122 and the hinge seat body 121 may be integrally formed, or the first reinforcement member 122 and the hinge seat body 121 may be a split structure.

[0055] Exemplarily, along the target axis, the first reinforcement 122 extends from one end of the hinge seat body 121 to the other end of the hinge seat body 121 to improve the connection strength between the first reinforcement 122 and the hinge seat body 121 and the integrity of the second hinge seat 12 .

[0056] For example, see Figure 1 and Figure 5 The first hinge seat 11 has a third fixing hole 11 a, and a screw passes through the third fixing hole 11 a to fix the first hinge seat 11.

[0057] Exemplarily, the manner in which the hinge seat body 121 is rotatably connected to the first hinge seat 11 is not limited.

[0058] Exemplarily, the first hinge seat 11 can rotate relative to the hinge seat body 121 .

[0059] Exemplarily, the hinge 1 further includes a rotating shaft, and the first hinge seat 11 and the hinge seat body 121 are both rotatably connected to the rotating shaft.

[0060] In one embodiment, please refer to Figure 1 , Figure 4 and Figure 5 There are multiple second fixing holes 121a, and the multiple second fixing holes 121a are arranged at intervals along the target axis. The first fixing hole 122a is located between two second fixing holes 121a along the target axis.

[0061] In the embodiment of the present application, the first fixing hole 122a is located between the two second fixing holes 121a. On the one hand, the first fixing hole 122a and the two second fixing holes 121a form an acute triangle in space, which is beneficial to reducing the length of the second hinge seat 12 along the target axis, so that the spatial distribution of the first fixing hole 122a and the second fixing hole 121a is more reasonable; on the other hand, the screws passing through the first fixing hole 122a and the second fixing hole 121a also form an acute triangle in space. During the rotation of the first hinge seat 11 relative to the second hinge seat 12, the screws forming the acute triangle are subjected to more uniform force.

[0062] Exemplarily, the number of the first fixing holes 122a may be one or two.

[0063] Exemplarily, the number of the second fixing holes 121 a may be two or three.

[0064] Exemplarily, the number of the first fixing hole 122a is one, the number of the second fixing holes 121a is three, the three second fixing holes 121a are arranged in sequence along the target axis, and along the target axis, the first fixing hole 122a is located between two second fixing holes 121a.

[0065] It is understandable that the positional relationship between the first fixing hole 122a and the plurality of second fixing holes 121a is not limited. For example, along the target axis, the first fixing hole 122a may also be located outside the two second fixing holes 121a, so that the first fixing hole 122a and the two outermost second fixing holes 121a form an obtuse triangle in space.

[0066] It is understandable that the number of the second fixing holes 121a is not limited. For example, the number of the second fixing hole 121a can be one, the number of the first fixing hole 122a is also one, and the direction in which the first fixing hole 122a penetrates the first reinforcement member 122 intersects with the direction in which the second fixing hole 121a penetrates the hinge seat body 121.

[0067] In one embodiment, please refer to Figure 1 , Figure 4 and Figure 5 The number of the second fixing holes 121 a is two, and the distances between the two second fixing holes 121 a and the first fixing hole 122 a are equal.

[0068] In the embodiment of the present application, the distances between the two second fixing holes 121a and the first fixing hole 122a are equal. On the one hand, the first fixing hole 122a and the two second fixing holes 121a form an isosceles triangle in space, which is beneficial to reducing the length of the second hinge seat 12 along the target axis, so that the spatial distribution of the first fixing hole 122a and the second fixing hole 121a is more reasonable; on the other hand, the screws passing through the first fixing hole 122a and the second fixing hole 121a also form an isosceles triangle in space. During the rotation of the first hinge seat 11 relative to the second hinge seat 12, the screws forming the acute triangle are subjected to more uniform force.

[0069] For example, see Figure 5 In the figure, the dotted lines R1 and R2 are the distances between the first fixing hole 122a and the two second fixing holes 121a, respectively. R1 and R2 are equal, so that the first fixing hole and the two second fixing holes 121a form an isosceles triangle in space.

[0070] Exemplarily, the distance between the first fixing hole 122a and the second fixing hole 121a and the distance between the two second fixing holes 121a are not limited in size.

[0071] Exemplarily, the distance between the first fixing hole 122a and the second fixing hole 121a is equal to the distance between the two second fixing holes 121a, and the first fixing hole 122a and the two second fixing holes 121a form an equilateral triangle in space.

[0072] It is understandable that the distance between the two second fixing holes 121a and the first fixing hole 122a is not limited. For example, the distance between the two second fixing holes 121a and the first fixing hole 122a may also be unequal.

[0073] In one embodiment, please refer to Figure 1 to Figure 5 The second hinge seat 12 further includes a second reinforcement member 123 , and the second reinforcement member 123 is disposed on a side of the hinge seat body 121 away from the first reinforcement member 122 .

[0074] In the embodiment of the present application, the second reinforcement 123 is arranged on the side of the hinge seat body 121 away from the first reinforcement 122. On the one hand, the second reinforcement 123 can increase the rigidity and strength of the hinge seat body 121, and then reduce the thickness of the hinge seat body 121 to save costs while ensuring the rigidity and strength of the second hinge seat 12. On the other hand, the thickness of the hinge seat body 121 is relatively small, and the hinge seat body 121 is prone to bending or deformation in the thickness direction. The second reinforcement 123 increases the rigidity and strength of the hinge seat body 121 along the thickness direction, which is beneficial to extending the service life of the second hinge seat 12.

[0075] Exemplarily, the arrangement direction of the second reinforcement member 123 is not limited.

[0076] For example, see Figure 1 to Figure 5 Along the arrangement direction of the first fixing hole 122a and the second fixing hole 121a, the second reinforcement 123 can extend from one end of the hinge seat body 121 to the other end of the hinge seat body 121. During the rotation of the first hinge seat 11 relative to the second hinge seat 12, the bending moment of the hinge seat body 121 along the arrangement direction of the first fixing hole 122a and the second fixing hole 121a is relatively large. The second reinforcement 123 arranged along this direction can better resist the large bending moment to extend the service life of the hinge seat body 121.

[0077] Exemplarily, along the target axis, the second reinforcement member 123 may extend from one end of the hinge seat body 121 to the other end of the hinge seat body 121 .

[0078] Exemplarily, the second reinforcement member 123 may also be extended in a direction inclined to the target axis.

[0079] Exemplarily, the second reinforcement member 123 and the hinge seat body 121 are formed in any manner.

[0080] Exemplarily, the second reinforcement member 123 and the hinge seat body 121 may be integrally formed, or the second reinforcement member 123 and the hinge seat body 121 may be a split structure.

[0081] In one embodiment, please refer to Figure 1 to Figure 5 The number of the second reinforcement members 123 is multiple, and the multiple reinforcement members are arranged at intervals along the target axis.

[0082] In the embodiment of the present application, a plurality of second reinforcement members 123 are arranged at intervals along the target axis. On the one hand, the thickness of the hinge seat body 121 is relatively small, and the hinge seat body 121 is prone to bending or deformation in the thickness direction. The plurality of second reinforcement members 123 arranged at intervals improve the stiffness and strength of the hinge seat body 121 in the thickness direction, so as to improve the bending resistance of the hinge seat body 121 in the thickness direction, which is beneficial to extending the service life of the second hinge seat 12; on the other hand, the plurality of second reinforcement members 123 arranged at intervals cooperate with the hinge seat body 121 to expand the range of the second reinforcement members 123 to improve the stiffness and strength of the hinge seat body 121 along the target axis, thereby further extending the service life of the second hinge seat 12.

[0083] For example, the number of the second reinforcement members 123 is not limited.

[0084] For example, see Figure 4 and Figure 5There are four second reinforcement members 123. Along the arrangement direction of the first fixing hole 122a and the second fixing hole 121a, the second reinforcement member 123 extends from one end of the hinge seat body 121 to the other end of the hinge seat body 121. Along the target axis, the four second reinforcement members 123 are arranged at intervals.

[0085] Exemplarily, the number of the second reinforcement member 123 may also be one, and along the arrangement direction of the first fixing holes 122a and the second fixing holes 121a, the second reinforcement member 123 extends from one end of the hinge seat body 121 to the other end of the hinge seat body 121.

[0086] It is understandable that the second hinge seat 12 may not include the second reinforcement member 123. Exemplarily, the second hinge seat 12 includes a hinge seat body 121 and a first reinforcement member 122, and the hinge seat body 121 has sufficient thickness to meet the bending resistance of the hinge seat body 121 in the thickness direction.

[0087] In one embodiment, please refer to Figure 1 and Figure 5 The second fixing hole 121 a is located between two adjacent second reinforcement members 123 .

[0088] In the embodiment of the present application, the second fixing hole 121a is located between two adjacent second reinforcement members 123, so that the second fixing holes 121a and the second reinforcement members 123 can be alternately arranged along the target axis, so that on the path where the second reinforcement members 123 extend, the second reinforcement members 123 will not be occupied by the second fixing holes 121a, which is beneficial to increase the length of the second reinforcement members 123, improve the strength of the hinge seat body 121, and also make the second fixing holes 121a and the second reinforcement members 123 more reasonably arranged in space.

[0089] It should be noted that the second fixing hole 121 a is located between two adjacent second reinforcement members 123 , which means that there may be a second fixing hole 121 a between two adjacent second reinforcement members 123 , or there may be no second fixing hole 121 a between two adjacent second reinforcement members 123 .

[0090] For example, see Figure 5 There are four second reinforcement members 123 , which are arranged at intervals along the target axis. There are two second fixing holes 121 a , which are respectively located between the two leftmost second reinforcement members 123 and between the two rightmost second reinforcement members 123 . No second fixing hole 121 a is arranged between the two middle second reinforcement members 123 .

[0091] It is understandable that the positional relationship between the second fixing hole 121a and the second reinforcement 123 is not limited. Exemplarily, the second fixing hole 121a may also be located on the path where the second reinforcement 123 extends, so that the second reinforcement 123 is disconnected at the position of the second fixing hole 121a.

[0092] In one embodiment, please refer to Figure 1 and Figure 5 The direction in which the first fixing hole 122a penetrates the first reinforcement member 122 is the first direction, and the second fixing hole 121a is a waist-shaped hole, and the second fixing hole 121a extends along the first direction.

[0093] In the implementation of the present application, when the screw located in the first fixing hole 122a fixes the second hinge seat 12, the adjustment range of the hinge seat body 121 along the first direction is limited. Under the objective condition that the hinge seat body 121 has a dimensional error, there is a possibility that the screw cannot pass through the second fixing hole 121a. The second fixing hole 121a extends along the first direction into a waist-shaped hole, which indirectly increases the adjustment range of the second hinge seat 12 along the first direction to reduce the impact of the dimensional error of the hinge seat body 121, which is conducive to the screw smoothly passing through the second fixing hole 121a to tighten the hinge seat body 121.

[0094] It is understandable that the shape of the second fixing hole 121a is not limited. For example, the second fixing hole 121a may also be a round hole.

[0095] A second aspect of the present application provides a refrigeration device. Figure 1 to Figure 7 , including a hinge 1, a box body 2, a connecting piece and a door body 3. The second hinge seat 12 is installed on the box body 2, at least one connecting piece passes through the first fixing hole 122a to connect the first reinforcement member 122 with the box body 2, at least one connecting piece passes through the second fixing hole 121a to connect the hinge seat body 121 with the box body 2, and the door body 3 is connected to the first hinge seat 11, so that the door body 3 can rotate relative to the box body 2.

[0096] In the embodiment of the present application, the direction in which the first fixing hole 122a penetrates the first reinforcement 122 intersects with the direction in which the second fixing hole 121a penetrates the hinge seat body 121, so that the connecting member can apply a tightening force to the second hinge seat 12 in two different directions. In the case that the connecting member in one direction is loose, the connecting member can still constrain the movement of the second hinge seat 12 in the other direction, and cooperate with the tightening force applied by the connecting member that is not loose in the other direction, so that the second hinge seat 12 can still be fixed relatively firmly. Furthermore, in the case that the connecting members in both directions are loose, the connecting members in the two directions are arranged crosswise, which can also provide the second hinge seat 12 with two different directions of restraining force, and then fix the second hinge seat 12 relatively stably, which is conducive to improving the connection strength of the hinge 1.

[0097] Exemplarily, the type of the connecting member is not limited, and may be a screw, for example.

[0098] In one embodiment, please refer to Figure 1 to Figure 7 The box body 2 includes an outer shell 21, an inner liner 22 and a mouth frame 23. The inner liner 22 is arranged in the outer shell 21. The inner liner 22 and the outer shell 21 enclose a heat preservation chamber 2a. The heat preservation chamber 2a surrounds the outer side of the inner liner 22. The mouth frame 23 is respectively connected to the outer shell 21 and the inner liner 22 to close the heat preservation chamber 2a. At least one connecting member passes through the first fixing hole 122a to connect the first reinforcement 122 to the mouth frame 23. At least one connecting member passes through the second fixing hole 121a to connect the hinge seat body 121 to the outer shell 21.

[0099] In the embodiment of the present application, on the one hand, the box body 2 and the door body 3 are rotatably connected by the hinge 1, so that the door body 3 can rotate relatively smoothly relative to the box body 2 to realize the normal opening and closing function of the refrigeration equipment; on the other hand, the outer shell 21 is connected to the hinge seat body 121, the mouth frame 23 is connected to the first reinforcement 122, and the hinge seat body 121 and the first reinforcement 122 are arranged crosswise, so that the second hinge seat 12 can tightly buckle the mouth frame 23 between the outer shell 21 and the inner liner 22, which is beneficial to improve the connection strength between the mouth frame 23 and the outer shell 21 and the inner liner 22.

[0100] In one embodiment, please refer to Figure 2 and Figure 3 The surface of the mouth frame 23 close to the door body 3 includes a first surface 23a and a second surface 23b, the second surface 23b is located on the side of the first surface 23a away from the hinge 1, the first surface 23a has a first mounting hole 23aa, at least one connecting member passes through the first fixing hole 122a and the first mounting hole 23aa to connect the first reinforcement 122 to the mouth frame 23, and along the direction of the first fixing hole 122a passing through the first reinforcement 122, the surface of the first reinforcement 122 close to the door body 3 is located on the side of the second surface 23b close to the outer shell 21.

[0101] In the embodiment of the present application, the surface of the first reinforcement 122 close to the door body 3 is located on the side of the second surface 23b close to the outer shell 21, so that when the refrigeration equipment is in a closed state, the first reinforcement 122 will not protrude from the second surface 23b of the mouth frame 23 along the first direction, thereby allowing the door body 3 to fit tightly with the mouth frame 23, which is beneficial to improving the airtightness and thermal insulation effect of the refrigeration equipment.

[0102] It should be noted that the surface of the first reinforcement 122 close to the door body 3 is located on the side of the second surface 23b close to the outer shell 21, which means that the surface of the first reinforcement 122 close to the door body 3 is located between the first surface 23a and the second surface 23b along the first direction, or it can be that along the first direction, the surface of the first reinforcement 122 close to the door body 3 is located in the same plane as the second surface 23b.

[0103] Exemplarily, along the first direction, the surface of the first reinforcement 122 close to the door body 3 and the second surface 23b are located in the same plane, which is beneficial to improving the flatness of the appearance of the refrigeration equipment.

[0104] For example, see Figure 6 and Figure 7 The first mounting hole 23aa can be a screw column to increase the matching area between the connecting member and the mouth frame 23, thereby increasing the connection strength between the mouth frame 23 and the first reinforcement member 122.

[0105] It is understandable that the positional relationship between the surface of the first reinforcement 122 close to the door body 3 and the second surface 23b is not limited. For example, along the first direction, the surface of the first reinforcement 122 close to the door body 3 is located on the side of the second surface 23b away from the housing 21.

[0106] In one embodiment, please refer to Figure 2 and Figure 3 The hinge seat body 121 also includes a screw plate 1215, which is arranged on one side of the outer shell 21 close to the inner shell 22 and is located at the connection position between the hinge seat body 121 and the outer shell 21. The hinge seat body 121 has a second mounting hole 21a, and at least one connecting member passes through the second fixing hole 121a and the second mounting hole 21a to connect the hinge seat body 121 with the outer shell 21.

[0107] In the embodiment of the present application, the screw plate 1215 is arranged on one side of the outer shell 21 close to the inner shell 22, and is located at the connection position between the hinge seat body 121 and the outer shell 21. On the one hand, the screw plate 1215 and the hinge seat body 121 cooperate with each other, so that the hinge seat body 121 is fastened to the outer shell 21; on the other hand, the screw plate 1215 can improve the strength and rigidity of the outer shell 21 at the cooperation position with the hinge seat body 121, so as to reduce the possibility of bending or deformation of the outer shell 21 at the cooperation position with the hinge seat body 121, which is beneficial to extend the service life of the outer shell 21.

[0108] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 8The extension direction of the rotation center line of the first hinge seat 11 and the second hinge seat 12 is arranged to cross the up and down direction, so that the door body 3 can rotate in the up and down direction relative to the box body 2, and then the refrigeration equipment can be opened and closed in the up and down direction.

[0109] Exemplarily, the refrigeration device may be a refrigerator, which may be opened and closed in an up and down direction.

The stop cover 5 and the mouth frame 23 are surrounded by an installation cavity 232. The stop cover 5 has a stop portion 51 located on the side of the installation cavity 232 facing the door body 3. The target axis is located on the side of the stop portion 51 facing the mouth frame 23 along the axial direction of the take-and-release hole 231. The hinge 1 is at least partially located in the installation cavity 232, so that the stop portion 51 limits the hinge 1 from moving away from the mouth frame 23 along the axial direction of the take-and-release hole 231.

[0111] In the embodiment of the present application, a stop cover 5 and a mouth frame 23 are provided to enclose an installation cavity 232, and the hinge 1 is at least partially located in the installation cavity 232 so that the hinge 1 is connected to the mouth frame 23. The target axis is located on the side of the stop portion 51 along the axial direction of the access hole 231 toward the mouth frame 23, which can limit the hinge 1 from moving away from the mouth frame 23, prevent the hinge 1 from escaping from the installation cavity 232 of the mouth frame 23, and strengthen the connection between the hinge 1 and the mouth frame 23.

[0112] In one embodiment, please refer to Fig.10 and Fig.11 The stop cover 5 is arranged across the first hinge seat 11 and the second hinge seat 12 along the target axis, and the shape of the stop cover 5 is an arc.

[0113] Exemplarily, the parts of the first hinge seat 11 and the second hinge seat 12 located in the installation cavity 232 are arc-shaped structures.

[0114] In the embodiment of the present application, the first hinge seat 11 rotates relative to the second hinge seat 12. The arc-shaped stop cover 5 can leave space for the rotation of the first hinge seat 11 as much as possible while limiting the movement of the hinge 1, thereby reducing the interference of the stop cover 5 on the rotation of the first hinge seat 11.

[0115] It is understandable that the shape of the stop cover 5 is not limited to an arc shape. Exemplarily, the shape of the stop cover 5 is a square.

[0116] In one embodiment, please refer to Fig. 9 , Fig.10 and Fig.11The first hinge seat 11 has a third surface 111 and a fourth surface 112 that can be at least partially moved out of or out of the installation cavity 232.

The third reinforcement member 53 can further strengthen the covering of the first hinge seat 11, reduce the movement of the hinge 1, and improve the connection strength between the hinge 1 and the mouth frame 23. The space enclosed by the third reinforcement member 53 and the cover body 52 is used to avoid the fourth surface 112.

[0118] It is understandable that the distance from the fourth surface 112 to the target axis is not limited. Exemplarily, the distance from the fourth surface 112 to the target axis is less than or equal to the distance from the third surface 111 to the target axis.
