[0033] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0034] In the related art, an opening and closing device includes a device main body, a door body, and a hinge mechanism. The hinge mechanism includes a hinge fixed seat and a hinge rotating seat. The hinge fixed seat includes a first hinge main body portion and a first housing connecting portion, and the hinge rotating seat includes a second hinge main body portion and a second housing connecting portion. A first mounting hole is provided on the first housing connecting portion, and a second mounting hole is provided on the second housing connecting portion. Screws pass through the first mounting hole to connect the device main body with the hinge fixed seat, and screws pass through the second mounting hole to connect the hinge rotating seat with the door body.

[0035] In one embodiment, in order to install the hinge fixed seat fixed by screws on the device main body, screw holes need to be pre-set on the device main body. And in order to prevent the leakage of foam or foaming glue, the screws need to be pre-installed in the first mounting hole to block the first mounting hole when the device main body is foamed. At this time, the hinge fixed seat has not been installed yet. After the device main body is foamed, the pre-installed screws must be removed again to prepare for the installation of the hinge fixed seat. Then the hinge fixed seat is aligned and fixed with screws or bolts. That is to say, for the fixation of the device main body and the hinge fixed seat, the screws need to be installed, removed, and reinstalled, which leads to a cumbersome work process in the installation process of the device main body and the hinge fixed seat of the opening and closing device, reducing the convenience of using the device main body. Moreover, structures such as screws are exposed, and when applied to opening and closing devices such as refrigerators, the screws are easily corroded by the environment and further affect the overall aesthetics of the device main body.

[0036] To solve the problem of inconvenient installation of the device main body and the hinge fixed seat in the related art, the present disclosure embodiment provides a device main body of an opening and closing device and an opening and closing device. The following will describe in detail the device main body of the opening and closing device of the present disclosure embodiment with reference to the drawings.

[0037] Figure 1Schematic diagram of the device body of the opening and closing device according to an embodiment of the present disclosure; Figure 2 Schematic diagram of the device body and the hinge fixing seat according to an embodiment of the present disclosure; Figure 3 Schematic diagram of the back of the hinge fixing seat according to an embodiment of the present disclosure; Figure 4 Schematic diagram of the installation of the device body and the hinge mechanism according to an embodiment of the present disclosure; Figure 5 Explosion schematic diagram of the device body and the hinge mechanism according to an embodiment of the present disclosure. Refer to Figures 1 to 5 As shown, an embodiment of the present disclosure provides a device body of an opening and closing device. Specifically, the device body 1 includes a housing 10 and a first limit fixing structure 20. Among them, the housing 10 is provided with a first accommodation section S1, and the first accommodation section S1 is used to install the fixed hinge seat 30 of the hinge mechanism 3. The first limit fixing structure 20 is engaged and assembled with the fixed hinge seat 30. The first limit fixing structure 20 includes a first limit portion 20a, a second limit portion 20b, and a third limit portion 20c. The first limit portion 20a cooperates with the fixed hinge seat 30 to limit the freedom degree of the fixed hinge seat 30 in the horizontal direction and perpendicular to the length direction of the first accommodation section S1. The second limit portion 20b cooperates with the fixed hinge seat 30 to limit the freedom degree of the fixed hinge seat 30 in the horizontal direction and along the length direction of the first accommodation section S1. The third limit portion 20c cooperates with the fixed hinge seat 30 to limit the freedom degree of the fixed hinge seat 30 in the vertical direction.

[0038] Exemplarily, the opening and closing device can be a freezer, doors and windows (such as car doors), and folding furniture. For example, when the opening and closing device is a freezer, the device body 1 can represent the cabinet of the freezer.

[0039] As Figure 2 shown, exemplarily, the first accommodation section S1 can be a groove provided on the housing 10. For example, the first accommodation section S1 can be a concave shape adapted to the fixed hinge seat 30 of the hinge mechanism 3, so that after the fixed hinge seat 30 is installed on the housing 10 of the device body 1, it can be completely accommodated in the first accommodation section S1. The first limit fixing structure 20 can be provided in the first accommodation section S1. The hinge fixing seat 30 can include a first hinge main body portion 31 and a first outer shell connection portion 32. The first hinge main body portion 31 is cylindrical, and a accommodation space is formed at an interval from the bottom of the first outer shell connection portion 32 relative to the first hinge main body portion 31. In this way, after the hinge fixing seat 30 is fixed to the device body 1, the limit structure between the hinge fixing seat 30 and the device body 1 can be hidden, thereby improving the overall aesthetic appearance after the hinge fixing seat 30 is fixed and further meeting the user's needs.

[0040] Refer to Figure 1 and Figure 2As shown, exemplarily, the first limit fixing structure 20 is engaged and assembled with the fixed hinge seat 30. The first limiting portion 20a cooperates with the fixed hinge seat 30 to define the degree of freedom of the fixed hinge seat 30 in the horizontal direction and perpendicular to the length direction of the first accommodation interval S1. The first limiting portion 20a is disposed in the first accommodation interval S1 and is arranged along the length direction of the first accommodation interval S1. A limiting structure corresponding to the first limiting portion 20a is provided on the fixed hinge seat 30. The first limiting portion 20a and the limiting structure on the fixed hinge seat 30 can be set according to actual usage requirements.

[0041] Referring Figure 1 and Figure 2 As shown, exemplarily, the second limiting portion 20b cooperates with the fixed hinge seat 30 to define the degree of freedom of the fixed hinge seat 30 in the horizontal direction and along the length direction of the first accommodation interval S1. The second limiting portion 20b is located within the first accommodation interval. A limiting structure corresponding to the second limiting portion 20b is provided on the fixed hinge seat 30. The specific structure of the second limiting portion 20b can be set according to actual usage requirements, as long as it can satisfy the degree of freedom of the fixed hinge seat in the horizontal direction and along the length direction of the first accommodation interval S1.

[0042] Referring Figure 1 and Figure 2 As shown, exemplarily, the third limiting portion 20c cooperates with the fixed hinge seat 30 to define the degree of freedom of the fixed hinge seat 30 in the vertical direction. The third limiting portion 20c is used to define the degree of freedom in the vertical direction. A limiting structure corresponding to the third limiting portion 20c is provided on the fixed hinge seat 30. The specific structure of the third limiting portion 20c can be set according to actual usage requirements.

[0043] In the related art, a first mounting hole is provided on the first housing connection part of the fixed hinge seat 30, and a screw passes through the first mounting hole to be connected to the device main body. In actual installation, in order to prevent the foaming agent from leaking, screws need to be installed in advance. After the screws are installed in the first mounting hole, the first mounting hole can be blocked. After the foaming process of the device main body is completed, the screws are removed, and finally the hinge fixing seat and the device main body are fixed by screws. Such a method results in a cumbersome installation process of the device main body, inconvenient use, and the screws and the like may also be exposed outside, which not only affects the overall aesthetics of the device main body, but also the screws may be corroded and damaged due to the use environment of the freezer. For the device main body of the opening and closing device in the embodiment of the present disclosure, the housing 10 is provided with a first accommodating section S1, and the first accommodating section S1 is used for installing the fixed hinge seat 30 of the hinge mechanism. The first limiting and fixing structure 20 is engaged and assembled with the fixed hinge seat 30. The first limiting and fixing structure 20 includes a first limiting portion 20a, a second limiting portion 20b, and a third limiting portion 20c. The first limiting portion 20a cooperates with the fixed hinge seat 30 to limit the freedom degree of the fixed hinge seat 30 in the horizontal direction and perpendicular to the length direction of the first accommodating section S1. The second limiting portion 20b cooperates with the fixed hinge seat 30 to limit the freedom degree of the fixed hinge seat 30 in the horizontal direction and along the length direction of the first accommodating section S1. The third limiting portion 20c cooperates with the fixed hinge seat 30 to limit the freedom degree of the fixed hinge seat 30 in the vertical direction. By providing the first limiting and fixing structure 20 to be engaged with the fixed hinge seat 30, the device main body is not only convenient for installation and disassembly, but also does not require the use of fasteners such as screws, further improving the aesthetic degree after the device main body is fixed to the hinge fixing seat, and further meeting the user's use requirements.

[0044] Referring to Figures 1 to 3 As shown, in an exemplary embodiment, a first reinforcing protrusion 11 is provided on the housing 10, and a first reinforcing cavity K1 is provided at the bottom of the fixed hinge seat 30. The first reinforcing protrusion 11 can be inserted into the first reinforcing cavity K1, and the first reinforcing protrusion 11 forms the first limiting portion 20a.

[0045] Exemplarily, the fixed hinge seat 30 includes a first hinge main body portion 31 and a first housing connection portion 32. The first hinge main body portion 31 is provided with a first accommodation cavity along the axial direction of the first hinge main body portion 31. One end of the first housing connection portion 32 is connected to the first hinge main body portion 31, and the extending direction of the first housing connection portion 32 is perpendicular to the axial direction of the first hinge main body portion 31. The first strengthening cavity K1 is provided at the bottom of the first housing connection portion 12. The first strengthening protrusion 11 on the housing 10 is adapted to the first strengthening cavity K1 provided at the bottom of the first housing connection portion 32. When the first housing connection portion 32 of the hinge fixing seat 30 is connected to the device main body 1, the first strengthening protrusion 11 is inserted into the first strengthening cavity K1. Such a setting can increase the connection strength between the device main body 1 and the hinge fixing seat 30, and the first strengthening protrusion 11 of the device main body 1 can also play a limiting role on the hinge fixing seat through the first strengthening cavity K1, so that the hinge mechanism no longer leans backward after being stressed, achieving the anti-backward-tilting effect, and the hinge mechanism can be stable and reliable without loosening. The first strengthening cavity K1 can be formed by enclosing the first hinge main body portion, the first housing connection portion and the extension plate, and the hole of the first strengthening cavity K1 can be generally in the shape of a tapered hole.

[0046] The first limiting portion 20a of the embodiment of the present disclosure includes a first strengthening protrusion 11. The first strengthening protrusion 11 can be inserted into the first strengthening cavity K1. The first strengthening protrusion 11 can play a role in limiting the movement of the first strengthening cavity K1 in the length direction perpendicular to the first accommodation space. Thus, the first strengthening protrusion 11 and the first strengthening cavity K1 cooperate to limit the freedom degree of the fixed hinge fixing seat in the length direction of the first accommodation space. Moreover, the cooperation mode of the first strengthening protrusion 11 and the first strengthening cavity K1 of the hinge fixing seat 30 can increase the connection strength between the hinge fixing seat and the device main body. The first strengthening protrusion 11 can also play a limiting role on the hinge fixing seat through the first strengthening cavity K1, so that the hinge fixing seat no longer leans backward after being stressed, achieving the anti-backward-tilting effect.

[0047] Refer to Figures 1 to 3 As shown, in an exemplary embodiment, a plurality of third strengthening protrusions 12 are arranged at intervals along the length direction of the first accommodation interval S1. The bottom of the fixed hinge seat 30 is provided with second strengthening protrusions 33 at intervals along the length direction of the first accommodation interval S1. The adjacent third strengthening protrusions 12 form a limiting space, and the second strengthening protrusions 33 are inserted into the limiting space. The third strengthening protrusions 33 form a second limiting portion 20b.

[0048] Exemplarily, one end of the second strengthening protrusion 33 is connected to the first hinge main body portion. A limiting space is formed between the adjacent third strengthening protrusions 12. The second strengthening protrusion 33 is inserted into the limiting space formed by the third strengthening protrusions 22. The second strengthening protrusion 33 is limited in the freedom degree in the length direction of the first accommodation interval by the third strengthening protrusions 22 on both sides.

[0049] Referring to Figure 1 and Figure 2 As shown, in an exemplary embodiment, a clamping groove 13 is further provided on the housing 10. The clamping groove 13 can be arranged along a direction perpendicular to the length direction of the first accommodating section S1. The bottom of the fixed hinge seat 30 is vertically extended with a clamping plate 34 that is in clamping fit with the clamping groove 13, and the clamping groove 13 forms a third limiting part 20c.

[0050] Exemplarily, the clamping plates 34 are located on the opposite two side edges below the first housing connection part. The two clamping plates 34 are arranged oppositely and are perpendicular to the first housing connection part. The clamping plates 34 extend along the long side of the first housing connection part. The clamping plates 34 can be snap-fitted into the clamping groove 13, thereby limiting and fixing the hinge fixing seat in the vertical direction. It should be noted that the specific structures of the clamping plates 34 and the clamping groove 13 can be set according to actual use requirements and are not limited herein.

[0051] Referring to Figures 1 to 3 As shown, in an exemplary embodiment, the number of the first reinforcing protrusions 11 is at least one, and at least one first reinforcing protrusion 11 is arranged at intervals along the length direction of the first accommodating section S1. Such a setting can further strengthen the connection strength between the hinge fixing seat and the device main body and enhance the anti-rearward tilting effect. Exemplarily, the number of the first reinforcing protrusions 11 is three, and the three first reinforcing protrusions 11 are arranged in sequence along the length direction of the first accommodating space. It should be noted that the number, size and shape of the first reinforcing protrusions 11 can be set according to actual use requirements and are not limited herein.

[0052] Exemplarily, an extension plate is provided at the bottom of the first housing connection part of the hinge fixing seat. The extension plate is arranged along the length direction of the first accommodating space. An accommodating section is formed between the extension plate and the first hinge main body part. At least one partition plate is connected between the extension plate and the first hinge main body part, and each partition plate divides the accommodating section to form a first reinforcing cavity K1. The top end of the extension plate is connected to the first housing connection part, and there is a gap between the top end of the extension plate and the first hinge main body part. An accommodating section is formed between the outer walls of the extension plate and the first hinge main body part. The partition plates are arranged in the accommodating section, and one end of the partition plate is connected to the first hinge main body part, and the other end of the partition plate is connected to the extension plate, thereby dividing the accommodating section to form at least two first reinforcing cavities K1. For example, two partition plates divide the accommodating section to form three first reinforcing cavities. With such a setting, the extension plate can be used as a reinforcing rib to further strengthen the strength of the first housing connection part, and the partition plates can also be reinforcing ribs connecting the extension plate and the first hinge main body part.

[0053] It should be noted that the number of the first reinforcing protrusions 11 is one or more, and the number of the partition plates can be set according to actual usage requirements. For example, the number of the partition plates can be one, and the partition plate divides the accommodation area into left and right regions. The first reinforcing cavity K1 can also represent the left and right spaces formed by the partition plate dividing the accommodation area. That is to say, the first reinforcing cavity K1 can also be understood as a groove-like structure penetrating both sides. The specific shape and structure of the first reinforcing cavity K1 are not limited herein, as long as the first reinforcing cavity K1 can accommodate the first reinforcing protrusions and achieve the limiting function.

[0054] Exemplarily, part of the inner wall of the first reinforcing cavity is formed by the outer wall of the cylindrical first hinge main body part, so that the aperture of the first reinforcing cavity is integrally tapered, which can enhance the reliability of the connection between the first reinforcing cavity and the first reinforcing protrusions.

[0055] Referring to Figures 1 to 3 As shown, in an exemplary embodiment, at least two third reinforcing protrusions 12 are respectively provided corresponding to each of the first reinforcing protrusions 11, and one end of the third reinforcing protrusions 12 corresponding to each of the first reinforcing protrusions 11 is connected to the first reinforcing protrusion 11.

[0056] Exemplarily, one end of the third reinforcing protrusion 12 corresponding to the first reinforcing protrusion 11 is connected to the first reinforcing protrusion 11, so that the second reinforcing protrusion can be located in the first reinforcing cavity. The side of the third reinforcing protrusion 12 in contact with the hinge fixing seat is arc-shaped. Such a setting can further enhance the reliability of the limiting and fixing of the second reinforcing protrusion and the third reinforcing protrusion, and the first reinforcing cavity and the first reinforcing protrusion.

[0057] The design requirements of the device main body in the exemplary embodiment of the present disclosure are simple. The hinge fixing seat is a flat plug-in type, and it is not necessary to lift the device main body during installation, and it can be directly inserted. Moreover, due to the structural arrangement of the device main body, the hinge mechanism can be limited in three directions, and there is no risk of tilting and disengaging.

[0058] Referring to Figure 1 and Figure 2 As shown, in an exemplary embodiment, the card slots 13 are located on both sides of the first accommodation area S1, the card slots 13 extend along a direction perpendicular to the length direction of the first accommodation area S1, the card slots 13 include a first side wall 131 away from the first limiting portion 20a and a second side wall 132 close to the first limiting portion 20a, a first limiting groove 133 is provided on the first side wall 131, and a protruding portion 341 protruding toward the card slot 13 is provided on the snap plate 34, and the protruding portion 341 is in limiting cooperation and fixation with the first limiting groove 133.

[0059] Figure 6 is a top view of the device main body and the hinge mechanism in the exemplary embodiment of the present disclosure; Figure 7 is Figure 6Schematic diagram of the A-A section. Refer to Figure 6 and Figure 7 As shown, by way of example, the snap plate 34 may include a first wing plate 342 in a straight plate shape. A protruding portion 341 is provided on the first wing plate 342 protruding towards the outside of the card slot 13. A first limiting groove 133 is provided on the first side wall 131 of the card slot 13, and the protruding portion 341 is in limiting cooperation with the first limiting groove 133.

[0060] Refer to Figure 6 and Figure 7 As shown, by way of example, a protruding portion 341 is provided at one end of the first wing plate 342 away from the first housing connection portion. That is to say, the free end of the first wing plate 342 is provided with a protruding portion 341, and the free end of the first wing plate can move elastically relative to the left and right. The first wing plate 342 may be slightly smaller than the size of the first limiting groove 231. In this way, when the first wing plate 342 is inserted into the first limiting groove 133, the free end of the first wing plate 342 can be elastically deformed and restored to its initial state after entering the first limiting groove 133, so that the protruding portion 341 is in limiting cooperation and fixation with the first limiting groove 133.

With such a setting, a tool can be inserted into the gap between the upper side of the sliding-in surface of the first limiting groove 133 and the buckle plate, which facilitates the disassembly of the device body and the hinge fixing seat.

[0066] Referring to Figure 4 and Figure 5As shown, the embodiment of the present disclosure also provides an opening and closing device, including a device body 1, a hinge mechanism 3 and a door body of the opening and closing device of any embodiment of the present disclosure. The device body 1 has an opening. The hinge mechanism 3 includes a hinge fixing seat 30, a hinge rotating seat 40, a piston 50, an elastic member 60 and a connecting shaft 70. The hinge fixing seat 30 includes a first hinge body part 31, a first shell connecting part 32 and a second position-limiting fixing structure 37. The device body 1 and the hinge fixing seat 30 are matched and connected through the first position-limiting fixing structure 20 and the second position-limiting fixing structure 37. The hinge rotating seat 40 includes a second hinge body part 41 and a second shell connecting part 42. The second hinge body part 41 is rotatably connected with the first hinge body part 31. The second hinge body part 41 is axially penetrated and provided with a second accommodating cavity. The first hinge body part 31 is provided with a first matching structure, and the second hinge body part 41 is provided with an opening. The piston 50 is arranged in the second accommodating cavity. The piston 50 has a second matching structure, and the second matching structure abuts against the first matching structure through the opening. The elastic member 60 is disposed in the second accommodating cavity and is located at the end of the piston 50 away from the second matching structure. The elastic member 60 can provide assistance for the abutting state. The connecting shaft 70 passes through the first hinge body 31, the piston 50, the elastic member 60 and the second hinge body 41, so that the first hinge body 31 and the second hinge body 41 are relatively fixed in the axial direction. The door body is connected to the opening of the device body through the second shell connection part of the hinge rotating seat of the hinge mechanism.

[0067] Exemplarily, the material of the hinge fixing seat 30 and the hinge rotating seat 40 includes polyoxymethylene resin material. For example, the material of the hinge fixing seat 30 and the hinge rotating seat 40 can both be polyoxymethylene resin material. The specific material of the hinge fixing seat 30 and the hinge rotating seat 40 is not limited here and can be set according to actual use requirements.

[0068] In the disclosed embodiment, the elastic member 60 can provide assistance for the abutment state, and in the process of closing the door body, the problem of the rotatable panel and the fixed structure colliding violently due to the rapid descent of the rotatable panel can be alleviated, thereby improving the user experience. In addition, the piston 50 and the elastic member 60 are both arranged in the second accommodating cavity of the second hinge body 41, and the first hinge body 31, the piston 50, the elastic member 60 and the second hinge body 41 can be assembled and connected through the connecting shaft 70, the hinge is simple, the assembly is convenient, and the space occupied by the hinge mechanism is reduced.

[0069] In an exemplary embodiment, the hinge mechanism further includes a limiting structure, which includes a limiting protrusion and a limiting groove. The limiting protrusion is disposed on a side of the first housing connection portion close to the hinge rotating seat, and the limiting groove is disposed on a surface of the second housing connection portion facing away from the device body. When the door body of the opening and closing device is at the maximum opening and closing angle, at least a part of the limiting protrusion is clamped and pressed into the limiting groove. With such a setting, the limiting protrusion generates a force perpendicular to the axis of the hinge rotating seat on the second housing connection portion of the hinge rotating seat, thereby preventing the hinge rotating seat from being damaged by tensile force and improving the reliability and strength of the hinge mechanism.

[0070] In an exemplary embodiment, a first positioning is provided on the top surface of the first mating structure, and a second positioning is provided on the top surface of the second mating structure. The first positioning and the second positioning cooperate to position the initial state of the hinge mechanism. Exemplarily, the first positioning may be a circular protrusion, and the second positioning may be a circular depression. When the hinge mechanism is in the initial state, the circular protrusion and the circular depression cooperate to position the hinge mechanism to the initial state, and the initial state of the hinge mechanism will not change due to transportation or other external forces. Moreover, during installation, the circular protrusion and the circular depression cooperate. In this way, when the hinge mechanism is actually assembled to the device body, since the included angle range between the hinge fixing seat 30 and the hinge rotating seat 40 of the hinge during normal use of the door body is greater than or equal to 180°, the circular protrusion and the circular depression hardly function, so that the normal and smooth use of the hinge mechanism will not be affected.

[0071] Exemplarily, the opening and closing device of the present disclosure may be a freezer, or the opening and closing device may also be other devices that can be opened and closed, such as dishwashers and lockers.

[0072] Refer to Figure 2 and Figure 4 、 Figure 5 As shown, in an exemplary embodiment, a plurality of first reinforcing ribs 35 are disposed on a side of the first housing connection portion 32 facing away from the device body 1. The plurality of first reinforcing ribs 35 extend along the length direction of the first housing connection portion 32, and the plurality of first reinforcing ribs 35 are spaced apart.

[0073] Exemplarily, the first hinge main body portion 31 and the first housing connection portion 32 may be integrally formed by injection molding. A plurality of first reinforcing ribs 35 are disposed on a side of the first housing connection portion 32 facing away from the device body 1. The plurality of first reinforcing ribs 35 extend along the length direction of the first housing connection portion 32, and the plurality of first reinforcing ribs 35 are spaced apart. With such a setting, the strength of the first housing connection portion 32 can be enhanced.

[0074] In the related art, the first housing connection part 32 is connected to the device main body by screws, and the strength requirement for the first housing connection part 32 is relatively low. However, in the embodiments of the present disclosure, the first housing connection part 32 is fixed to the device main body 1 through the first limit fixing structure and the second limit fixing structure, and the strength requirement for the first housing connection part 32 is higher. In the embodiments of the present disclosure, by providing a plurality of first reinforcing ribs 35 on the first housing connection part 32, the strength of the first housing connection part 32 can be enhanced, so as to meet the strength requirement for fixing the first housing connection part 32 and the device main body 1 through the first limit fixing structure and the second limit fixing structure.

[0075] Referring to Figure 2 and Figure 4 、 Figure 5 As shown, in an exemplary embodiment, a second reinforcing rib 36 is further provided on the side of the first housing connection part 32 facing away from the device main body 1. The second reinforcing rib 36 is connected between adjacent first reinforcing ribs 35, and the second reinforcing ribs 36 are arranged in a crosswise manner. Such an arrangement can further enhance the strength of the first housing connection part 32, so as to meet the strength requirement for the first housing connection part 32 in the solution of the present disclosure to adopt screwless fixation.

[0076] Exemplarily, the first reinforcing rib 35 extends along the length direction of the first housing connection part 32, and the number of the first reinforcing ribs 35 is multiple, and the multiple first reinforcing ribs 35 are arranged at intervals. The second reinforcing rib 36 is arranged between adjacent first reinforcing ribs 35, and the second reinforcing ribs 36 are cross-connected to form a rhombus shape.
