[0028] The hinge mechanism and refrigeration equipment provided by the utility model are described in detail below in conjunction with the embodiments.

[0030] See also Figure 1 , Figure 2 as well as Figure 3 , Figure 1 This is a schematic structural diagram of an embodiment of the hinge mechanism of the present application at 180°; Figure 2 This is a schematic structural diagram of an embodiment of the hinge mechanism of the present application at 0°; Figure 3It is a structural schematic diagram of an embodiment of the hinge mechanism of the present application at 90 degrees. The present application provides a hinge mechanism 10. The hinge mechanism 10 is arranged between the door body of the equipment to be installed and the main body of the equipment to be installed. The hinge mechanism 10 includes a hinge assembly 1. The hinge assembly 1 includes at least a plurality of first connecting rods 11 and a plurality of second connecting rods 12. The number of the first connecting rods 11 can be two, three or more than three. The number of the second connecting rods 12 can be two, three or more than three. One end of the plurality of first connecting rods 11 is stacked and hinged to the door body of the equipment to be installed. One end of the plurality of first connecting rods 11 is stacked and arranged on the door body of the equipment to be installed. The plurality of first connecting rods 11 are hinged to the door body of the equipment to be installed. That is, the plurality of first connecting rods 11 rotate relative to the door body of the equipment to be installed at the same time.

[0031] One end of the plurality of second connecting rods 12 is stacked and hinged to the body of the device to be installed. One end of the plurality of second connecting rods 12 is stacked and arranged on the body of the device to be installed. The second connecting rod 12 is hinged to the body of the device to be installed. That is, the plurality of second connecting rods 12 are hinged to the body of the device to be installed at the same time.

[0032] The other ends of the plurality of first connecting rods 11 and the other ends of the plurality of second connecting rods 12 are staggered and stacked and hinged. The other ends of the plurality of first connecting rods 11 and the other ends of the plurality of second connecting rods 12 are staggered and stacked. The other ends of the plurality of first connecting rods 11 and the other ends of the plurality of second connecting rods 12 are hinged. That is, the other ends of the plurality of first connecting rods 11 and the other ends of the plurality of second connecting rods 12 rotate relative to each other.

[0033] The hinge assembly 1 forms a rotation plane during the movement of the door body of the device to be installed and the body of the device to be installed. The stacking direction of the multiple first connecting rods 11 and the stacking direction of the second connecting rods 12 are both perpendicular to the rotation plane. The number of the first connecting rods 11 and the number of the second connecting rods 12 can be determined according to actual conditions. In addition, the staggered stacking arrangement of the first connecting rods 11 and the second connecting rods 12 can be determined according to actual conditions.

[0034] When the number of the first connecting rods 11 and the number of the second connecting rods 12 are both two, along the stacking direction, the stacking manner of the two first connecting rods 11 and the two second connecting rods 12 can be: the other end of a first connecting rod 11, the other end of a second connecting rod 12, the other end of another first connecting rod 11, and the other end of another second connecting rod 12. Alternatively, the stacking manner of the two first connecting rods 11 and the two second connecting rods 12 can be the other end of a second connecting rod 12, the other end of a first connecting rod 11, the other end of another second connecting rod 12, and the other end of another first connecting rod 11.

[0035] When there are two first connecting rods 11 and three second connecting rods 12, along the stacking direction, the two first connecting rods 11 and the three second connecting rods 12 can be stacked in a manner as follows: the other end of a second connecting rod 12, the other end of a first connecting rod 11, the other end of another second connecting rod 12, the other end of another first connecting rod 11, and the other end of yet another second connecting rod 12.

[0036] When the number of the first connecting rods 11 is three and the number of the second connecting rods 12 is two, along the stacking direction, the three first connecting rods 11 and the two second connecting rods 12 can be stacked in a manner as follows: the other end of a first connecting rod 11, the other end of a second connecting rod 12, the other end of another first connecting rod 11, the other end of another second connecting rod 12 and the other end of yet another first connecting rod 11.

[0037] Of course, the number of first connecting rods 11 and the number of second connecting rods 12 can also be other numbers, and the staggered stacking manner of multiple first connecting rods 11 and multiple second connecting rods 12 can be limited according to the number of first connecting rods 11 and second connecting rods 12, which will not be repeated here.

[0038] Therefore, the hinge mechanism 10 increases the number of first connecting rods 11 and second connecting rods 12 to improve the strength of the hinge mechanism 10 itself, thereby improving the load capacity of the hinge mechanism 10, thereby reducing the risk of the hinge mechanism 10 breaking. One end of the multiple first connecting rods 11 is stacked and hinged with the door body of the equipment to be installed, and one end of the multiple second connecting rods 12 is stacked and hinged with the main body of the equipment to be installed, thereby improving the installation strength of the hinge mechanism 10 on the door body of the equipment to be installed and the main body of the equipment to be installed, thereby improving the load capacity of the hinge mechanism 10. In addition, the other ends of the multiple first connecting rods 11 and the other ends of the multiple second connecting rods 12 are staggered and stacked and hinged, thereby improving the connection strength between the other ends of the first connecting rods 11 and the other ends of the second connecting rods 12, further improving the strength of the hinge mechanism 10 itself, thereby improving the load capacity of the hinge mechanism 10.

[0039] In one embodiment, the hinge assembly 1 includes a plurality of third connecting rods 13 and a plurality of fourth connecting rods 14. One end of the plurality of third connecting rods 13 is stacked and hinged to the door body of the equipment to be installed. One end of the plurality of third connecting rods 13 is stacked and arranged on the door body of the equipment to be installed. The plurality of third connecting rods 13 are hingedly arranged with the door body of the equipment to be installed. That is, the plurality of third connecting rods 13 rotate relative to the door body of the equipment to be installed at the same time.

[0040] One end of the plurality of fourth connecting rods 14 is stacked and hinged to the body of the device to be installed. One end of the plurality of fourth connecting rods 14 is stacked and arranged on the body of the device to be installed. The fourth connecting rod 14 is hinged to the body of the device to be installed. That is, the plurality of fourth connecting rods 14 rotate relative to the body of the device to be installed at the same time.

[0041] The other ends of the plurality of third links 13 and the other ends of the plurality of fourth links 14 are staggered and stacked and hinged. The other ends of the plurality of third links 13 and the other ends of the plurality of fourth links 14 are staggered and stacked. The other ends of the plurality of third links 13 and the other ends of the plurality of fourth links 14 are hinged. That is, the other ends of the plurality of third links 13 and the other ends of the plurality of fourth links 14 rotate relatively.

[0042] The middle parts of the plurality of second connecting rods 12 and the middle parts of the plurality of third connecting rods 13 are staggered and stacked and hinged. The other ends of the plurality of second connecting rods 12 and the other ends of the plurality of third connecting rods 13 are staggered and stacked. The other ends of the plurality of second connecting rods 12 and the other ends of the plurality of third connecting rods 13 are hinged. That is, the other ends of the plurality of second connecting rods 12 and the other ends of the plurality of third connecting rods 13 rotate relative to each other.

[0043] Therefore, the hinge mechanism 10 further includes a plurality of third connecting rods 13 and a plurality of fourth connecting rods 14, which increases the number of connecting rods in the hinge assembly 1 and further improves the strength of the hinge mechanism 10 itself. One end of the plurality of third connecting rods 13 is stacked and hinged with the door body of the equipment to be installed, and one end of the plurality of fourth connecting rods 14 is stacked and hinged with the body of the equipment to be installed, which further improves the installation strength of the hinge mechanism 10 on the door body of the equipment to be installed and the body of the equipment to be installed, thereby improving the load capacity of the hinge mechanism 10. In addition, the other ends of the plurality of third connecting rods 13 and the other ends of the plurality of fourth connecting rods 14 are staggered and stacked and hinged, which improves the connection strength between the other ends of the third connecting rods 13 and the other ends of the fourth connecting rods 14, and further improves the strength of the hinge mechanism 10 itself. At the same time, the middle parts of multiple second links 12 and the middle parts of multiple third links 13 are staggered and hinged, so that there is a certain connection relationship between the first link 11, the second link 12 and the third link 13 and the fourth link 14, thereby improving the strength of the hinge mechanism 10 and further improving the load capacity of the hinge mechanism 10.

[0044] The number of the third connecting rods 13 can be two, three or more than three. The number of the fourth connecting rods 14 can be two, three or more than three. The number of the third connecting rods 13 and the number of the fourth connecting rods 14 can be determined according to actual conditions and are not limited here.

[0045] There are many ways of staggered stacking. One way of stacking is to stack two different connecting rods one by one, or stack two, three or more connecting rods of one type and stagger them between connecting rods of another type. Another way of staggered stacking is to stack all connecting rods of one type and all connecting rods of another type, wherein one connecting rod is stacked on the upper end or lower end of all connecting rods of another type.

[0046] Regarding the two different connecting rods, the staggered stacking method. For example, when the number of the third connecting rods 13 and the number of the fourth connecting rods 14 are both two, and the number of the first connecting rods 11 and the second connecting rods 12 are both two, along the stacking direction, the staggered stacking method of the two third connecting rods 13 and the two fourth connecting rods 14 can be: the other end of a third connecting rod 13, the other end of a fourth connecting rod 14, the other end of another third connecting rod 13 and the other end of another fourth connecting rod 14; the middle part of a third connecting rod 13, the middle part of a second connecting rod 12, the middle part of another third connecting rod 13 and the middle part of another second connecting rod 12.

[0047] Alternatively, the two third links 13 and the two fourth links 14 can be staggered and stacked in a manner of: the other end of a fourth link 14, the other end of a third link 13, the other end of another fourth link 14 and the other end of another third link 13; the middle part of a second link 12, the middle part of a third link 13, the middle part of another second link 12 and the middle part of another third link 13. When there are two third links 13 and three fourth links 14, along the stacking direction, the two third links 13 and the three fourth links 14 can be staggered and stacked in a manner of: the other end of a fourth link 14, the other end of a third link 13, the other end of another fourth link 14, the other end of another third link 13 and the other end of another fourth link 14; the middle part of a second link 12, the middle part of a third link 13, the middle part of another second link 12, the middle part of another third link 13 and the middle part of another second link 12.

[0048] When the number of the third links 13 is three and the number of the fourth links 14 is two, along the stacking direction, the three third links 13 and the two fourth links 14 can be staggered and stacked in a manner of: the other end of a third link 13, the other end of a fourth link 14, the other end of another third link 13, the other end of another fourth link 14 and the other end of another third link 13; the middle part of a third link 13, the middle part of a second link 12, the middle part of another third link 13, the middle part of another second link 12 and the middle part of another third link 13.

[0049] Of course, the number of third connecting rods 13 and the number of fourth connecting rods 14 can also be other numbers, and the staggered stacking method of multiple third connecting rods 13 and multiple fourth connecting rods 14 can be limited according to the number of third connecting rods 13 and fourth connecting rods 14; in addition, the staggered stacking method of multiple second connecting rods 12 and third connecting rods 13 can be limited according to the number of second connecting rods 12 and third connecting rods 13, which will not be described in detail here.

[0050] Continue reading Figures 1 to 3In addition to at least a plurality of first links 11, a plurality of second links 12, a plurality of third links 13, and a plurality of fourth links 14, the hinge assembly 1 may also include a plurality of fifth links (not shown in the figure), a plurality of sixth links (not shown in the figure), and a plurality of seventh links (not shown in the figure), etc. The number of links may be determined according to actual conditions and is not limited here. When the hinge assembly 1 includes at least a plurality of first links 11, a plurality of second links 12, a plurality of third links 13, and a plurality of fourth links 14, in order to achieve that the plurality of first links 11, a plurality of second links 12, a plurality of third links 13, and a plurality of fourth links 14 are interlaced and stacked with each other and articulated, and to avoid certain interference during the movement of the hinge mechanism 10, the number of the first links 11, the second links 12, the third links 13, and the fourth links 14 is limited to at least the following three distribution forms.

[0051] In the first specific embodiment, the number of the first connecting rods 11 and the number of the third connecting rods 13 are the same. The number of the second connecting rods 12 is greater than the number of the first connecting rods 11. The number of the first connecting rods 11 is greater than the number of the fourth connecting rods 14. That is, the number of the second connecting rods 12 is greater than the number of the first connecting rods 11 and the number of the third connecting rods 13 at the same time; the number of the first connecting rods 11 and the number of the third connecting rods 13 are greater than the number of the fourth connecting rods 14 at the same time. Because the length of the second connecting rod 12 is greater than the length of the other first connecting rods 11, the third connecting rod 13 and the fourth connecting rod 14 in the design process of the above-mentioned hinge assembly 1, in order to enhance the force condition of the second connecting rod 12, by making the number of the second connecting rod 12 greater than the number of the other first connecting rods 11, the third connecting rod 13 and the fourth connecting rod 14, the sinking amount of the hinge mechanism 10 when loading the load can be reduced, thereby improving the overall stiffness of the hinge mechanism 10. For example, the number of the first connecting rods 11 and the number of the third connecting rods 13 are both three. The number of the second connecting rods 12 is four. The number of the fourth connecting rods 14 is two.

[0052] In the second specific embodiment, the number of the first connecting rods 11 is equal to the number of the third connecting rods 13. The number of the second connecting rods 12 is equal to the number of the fourth connecting rods 14. The number of the first connecting rods 11 is less than the number of the second connecting rods 12. That is, the number of the second connecting rods 12 and the number of the fourth connecting rods 14 are both greater than the number of the first connecting rods 11, and at the same time, the number of the second connecting rods 12 and the number of the fourth connecting rods 14 are both greater than the number of the third connecting rods 13. Because the stress on the fourth connecting rod 14 is more serious during the design process of the above-mentioned hinge assembly 1, the number of the second connecting rods 12 and the number of the fourth connecting rods 14 are both greater than the number of the first connecting rods 11 and the number of the third connecting rods 13, so as to improve the overall stiffness of the hinge mechanism 10 and thus improve the operating stability of the hinge mechanism 10. For example, the number of the second connecting rods 12 and the number of the fourth connecting rods 14 are both four. The number of the first connecting rods 11 and the number of the third connecting rods 13 are both three.

[0053] In the third specific embodiment, the number of the first connecting rods 11, the number of the second connecting rods 12, the number of the third connecting rods 13 and the number of the fourth connecting rods 14 are the same, so as to improve the overall rigidity of the hinge mechanism 10. For example, the number of the first connecting rods 11, the number of the second connecting rods 12, the number of the third connecting rods 13 and the number of the fourth connecting rods 14 are all three.

[0054] Of course, in addition to the above three specific embodiments, there may be other quantity limitations among the first connecting rod 11, the second connecting rod 12, the third connecting rod 13 and the fourth connecting rod 14, and the specific embodiments are not limited.

[0055] In one embodiment, the number of the first connecting rods 11, the number of the second connecting rods 12, the number of the third connecting rods 13, and the number of the fourth connecting rods 14 is greater than or equal to two, and less than or equal to four. By limiting the number of the first connecting rods 11, the number of the second connecting rods 12, the number of the third connecting rods 13, and the number of the fourth connecting rods 14, not only the thickness of the hinge assembly 1 in the stacking direction is limited, reducing the temporary use of the hinge mechanism 10 for the door body of the equipment to be installed and the space of the equipment to be rotated; but also the number of connecting rods can be limited, the assembly efficiency of the hinge mechanism 10 is improved, and the occurrence of problems such as cumbersome assembly of the hinge mechanism 10 is reduced.

[0056] Specifically, the number of the first connecting rods 11 is two, three or four. The number of the second connecting rods 12 is two, three or four. The number of the third connecting rods 13 is two, three or four. The number of the fourth connecting rods 14 is two, three or four. The number of the first connecting rods 11, the number of the second connecting rods 12, the number of the third connecting rods 13 and the number of the fourth connecting rods 14 can be determined according to actual conditions and are not limited here.

[0057] In one embodiment, the hinge point between the first connecting rod 11 and the door body of the device to be installed is located at the top of the door body of the device to be installed. The hinge point between the second connecting rod 12 and the body of the device to be installed is located at the side of the body of the device to be installed. By limiting the hinge point position of the first connecting rod 11 on the door body of the device to be installed and the hinge point position of the second connecting rod 12 on the body of the device to be installed, the opening and closing angle between the body of the device to be installed can be increased; at the same time, it is also convenient for installation.

[0058] When the hinge assembly 1 further includes a third link 13 and a fourth link 14, the hinge point between the third link 13 and the door body of the device to be installed is also located at the top of the door body of the device to be installed. The hinge point between the fourth link 14 and the body of the device to be installed is located at the side of the body of the device to be installed.

[0059] In one embodiment, the second connecting rod 12 is arranged in an arc shape to form a first avoidance space (not shown in the figure) on the side of the second connecting rod 12 close to the door body of the equipment to be installed. The first avoidance space can be used to avoid the door body of the equipment to be installed. In addition, the third connecting rod 13 is also arranged in an arc shape to form a second avoidance space (not shown in the figure) on the side of the third connecting rod 13 close to the body of the equipment to be installed. The second avoidance space can be used to avoid the door body of the equipment to be installed.

By providing the above-mentioned fourth connecting member 24, fifth connecting member 25, sixth connecting member 26 and seventh connecting member 27, not only the connection stability between the connecting rods in the hinge mechanism 10 is improved, but also the friction between the connecting rods in the hinge mechanism 10 can be reduced, thereby improving the convenience of opening and closing the door body of the equipment to be installed relative to the main body of the equipment to be installed.

[0074] See also Figure 4 , Figure 5 as well as Figure 6 , Figure 4 It is a structural schematic diagram of an embodiment of the refrigeration equipment of the present application; Figure 5 yes Figure 4 A schematic diagram of the structure shown; Figure 6 This is a partial bottom view of an embodiment of the refrigeration device of the present application. Figures 1 to 3 , the present application provides a refrigeration device 100. The refrigeration device 100 includes a box body 1001, a door body 1002 and a hinge mechanism 10. The box body 1001 is the main body of the device to be installed. The door body 1002 can be rotatably arranged in the box body 1001, that is, the door body 1002 can be closed or opened relative to the box body 1001. The door body 1002 is the door body of the device to be installed. The hinge mechanism 10 is arranged between the box body 1001 and the door body 1002. It should be noted that the hinge mechanism 10 in this embodiment is the hinge mechanism 10 described in the above embodiment, and its specific structure is not limited. By using the hinge mechanism 10 in the above embodiment between the door body 1002 and the box body 1001, the refrigeration device 100 can improve the strength of the hinge mechanism 10, thereby improving the load capacity of the hinge mechanism 10, and then reducing the risk of the hinge mechanism 10 breaking.

[0075] In one embodiment, the door body 1002 can be relatively rotated to a first position and a second position through the hinge mechanism 10. When the door body 1002 is in the first position, the door body 1002 is in a closed state relative to the box body 1001. When the door body 1002 is in the second position, the door body 1002 is opened to the maximum position relative to the box body 1001. The maximum position is greater than or equal to 180°. The maximum position can be 180°, 190°, 200°, 230°, etc. The hinge mechanism 10 can be used to open the door at the maximum position, thereby meeting different angles, so that the door body 1002 completely avoids the side wall of the box body 1001, thereby meeting the use needs of different users.

[0076] In one embodiment, the door body 1002 forms a mounting groove 10021. The first mounting seat 5 in the hinge mechanism 10 is disposed in the mounting groove 10021. The second mounting seat 6 in the hinge mechanism 10 is disposed on an end surface of the box body 1001 facing the door body 1002. When the door body 1002 is closed relative to the box body 1001, the second mounting seat 6 is located in the mounting groove 10021. Through the above-mentioned arrangement, it is not only convenient to fold the hinge mechanism 10 in the mounting groove 10021, but also convenient to install and remove the hinge mechanism 10, and the door body 1002 is more closely fitted to the box body 1001.

[0077] The hinge mechanism 10 can be arranged between the top of the door body 1002 and the end surface of the box body 1001 facing the door body 1002. Alternatively, the hinge mechanism 10 can be arranged between the bottom of the door body 1002 and the end surface of the box body 1001 facing the door body 1002. When the hinge mechanism 10 is arranged between the bottom of the door body 1002 and the side end of the box body 1001, the refrigeration device 100 includes a self-locking member 202 and a self-locking buckle 201. The self-locking member 202 is arranged on the door body 1002 and close to the first mounting seat 5. The self-locking buckle 201 is arranged on the box body 1001 and close to the second mounting seat 6. When the door body 1002 is closed relative to the box body 1001, the self-locking member 202 is clamped in the self-locking buckle 201. The self-locking member 202 is used to lock the door body 1002 with the self-locking buckle 201 when the door body 1002 is in a closed state relative to the box body 1001, so as to prevent the door body 1002 from automatically opening when the door body 1002 is in a closed state relative to the box body 1001. When the door body 1002 needs to be opened relative to the box body 1001, the door body 1002 is pulled away from the box body 1001 to disengage the self-locking member 202 from the self-locking buckle 201. In addition, when the door body 1002 is in a closed state relative to the box body 1001 to a preset angle, the self-locking member 202 can provide the door body 1002 with a restoring force that automatically drives the door body 1002 to close relative to the box body 1001. Under the action of the restoring force, the door body 1002 can automatically close relative to the box body 1001.

[0078] The self-locking member 202 and the self-locking buckle 201 cooperate with each other to improve the convenience of closing the door body 1002 relative to the box body 1001, and at the same time, it can also reduce the risk of accidentally opening the door body 1002. Among them, the self-locking member 202 is arranged in the installation groove 10021. When the self-locking member 202 and the self-locking buckle 201 are engaged, the self-locking member 202 and the self-locking buckle 201 are both located in the installation groove 10021, so that the door body 1002 is more closely attached to the side end surface of the box body 1001.
