[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0039] The embodiment of the present application provides a junction box mounting structure, which aims to improve the installation sealing between the junction box 100 and the mounting body.

[0040] In the embodiments of this application, Figures 1 to 3 As shown, the junction box mounting structure includes a mounting body and a junction box 100. There are many wire harnesses and electrical components in electrical equipment, and the wiring harnesses and the wiring harnesses and the electrical components need to be connected through the terminal blocks 2. The junction box 100 refers to a component installed with the terminal blocks 2. The junction box mounting structure proposed in this application can be applied to any device having a junction box 100. In these devices, the position for installing the junction box 100 constitutes the mounting body. For example, the junction box mounting structure can be used in refrigeration equipment 1000. In some refrigeration equipment 1000, the junction box 100 is installed on the refrigerator liner 200. Accordingly, the refrigerator liner 200 constitutes the mounting body of the junction box mounting structure of this embodiment. In order to more clearly describe the technical solution of this application, the junction box mounting structure will be explained below using a refrigeration equipment 1000 embodiment as an example.

[0041] like Figure 6 and Figure 7 As shown, the mounting body has a mounting opening 4 and a protrusion 3 provided next to the mounting opening 4. Figure 4 、 Figure 5 and Figure 11 The junction box 100 includes a cover 1 and a terminal block 2. The terminal block 2 is mounted on the cover 1, which covers the mounting opening 4 and covers the outside of the raised portion 3. At least a portion of the cover 1 abuts against a side portion 6 of the mounting body near the mounting opening 4, and at least a portion of the cover 1 overlaps the raised portion 3.

[0042] Specifically, the mounting opening 4 is a hole that passes through the mounting body, and its shape can be any shape such as square, polygonal, circular, quasi-circular, special-shaped, etc., and this application does not limit this. The mounting opening 4 is used for the wiring harness and / or the terminal 2 to pass through. When the junction box 100 is installed on the mounting body, the wiring harness located on the side of the mounting body away from the cover body 1 can pass through the mounting opening 4 and be connected to the terminal 2 on the junction box 100; at the same time, the mounting opening 4 can also make way for the terminal 2 plugged into the cover body 1. For the convenience of description, the position on the mounting body close to the mounting opening 4, that is, the peripheral area surrounding the mounting opening 4, is defined as the side portion 6. The protrusion 3 is arranged next to the mounting opening 4, which means that the protrusion 3 is arranged on the periphery of the mounting opening 4, that is, it is arranged at the side portion 6.

[0043] like Figure 12 and Figure 13 As shown, the cover 1 is provided with a port, into which the terminal block 2 is plugged to enable installation of the terminal block 2 on the cover 1. The terminal block 2 is inserted into the port, and the two ends of the terminal block 2 installed on the cover 1 are located on opposite sides of the cover 1. When the cover 1 is placed over the mounting opening 4, the two ends of the terminal block 2 can be connected to the wiring harness or electrical components located on both sides of the mounting body. The cover 1 is placed over the mounting opening 4, sealing the mounting opening 4. The cover 1 and the side portion 6 can overlap with each other to form a partial contact area. At the same time, because the protrusion 3 is provided next to the mounting opening 4, when the cover 1 is placed over the mounting opening 4, the protrusion 3 is covered within the cover 1 and can also overlap with a portion of the cover 1 to form a contact area.

[0044] In the junction box installation structure provided by the present application, the cover body 1 can not only overlap with the side part 6, but also overlap with the raised portion 3, so that there is a larger contact area between the cover body 1 and the installation body, which expands the sealing surface, helps to better seal the connection between the cover body 1 and the installation body, improves the installation sealing of the junction box 100, and can avoid leakage of foam material during the foaming process; in addition, the raised portion 3 can also play a good limiting role on the cover body 1, avoiding the junction box 100 from deviating from the target position during installation, which helps to improve the installation accuracy of the junction box 100.

[0045] In some embodiments, the raised portion 3 and the mounting body are integrally formed, which helps to improve the strength of the raised portion 3; in addition, the one-piece molding design allows the raised portion 3 and the mounting body to be simultaneously prepared by casting, injection molding, die-casting, compression molding, 3D printing, etc., which simplifies the preparation steps and streamlines the parts.

[0046] In some embodiments, the cover body 1 and the mounting body may be sealed in these contact areas, for example, an adhesive layer or a sealant may be provided in the contact areas to achieve better sealing contact between the cover body 1 and the mounting body.

[0047] In some embodiments, the central region of the cover body 1 is recessed from the inner side of the cover body 1 facing the mounting opening 4 toward the outer side facing away from the mounting opening 4, forming a receiving groove 11 with a first flange 14 surrounding the inner side. The cover body 1 has a central region and a peripheral region surrounding the central region. The cover body 1 is structured such that the central region arches outward from the inside, thereby forming the receiving groove 11 on the inner side. The peripheral region forms the first flange 14 surrounding the receiving groove 11. When the cover body 1 is placed on the mounting opening 4, the first flange 14 and the side portion 6 are opposite and overlap each other, and the groove wall of the receiving groove 11 overlaps the raised portion 3.

[0048] The walls of the receiving groove 11 include a bottom wall 12 and side walls 13. The bottom wall 12 is opposite the mounting opening 4, and the side walls 13 are connected to and surround the bottom wall 12. In one embodiment, the top of the protrusion 3, facing away from the mounting body, abuts the bottom wall 12 of the receiving groove 11. The top of the protrusion 3 abuts the cover 1, expanding the sealing surface between the cover 1 and the mounting body, thereby improving the installation seal of the junction box 100. In addition, the top abutting the cover 1 also serves to limit the inside and outside directions of the cover 1. In another embodiment, the side of the protrusion 3, facing away from the mounting opening 4, abuts the side wall of the receiving groove 11. The side of the protrusion 3 abuts the cover 1. This not only expands the sealing surface between the cover 1 and the mounting body, but also provides further leak-proof protection at the joint between the first flange 14 and the mounting body, thereby further improving the installation seal of the junction box 100. It also serves as a limiter to prevent the junction box 100 from moving out of position. In some other embodiments, the top of the protrusion 3 abuts against the bottom wall 12 of the accommodating groove 11, and the side of the protrusion 3 facing away from the installation port 4 abuts against the side wall of the accommodating groove 11, and the top and side are both in contact with the cover body 1, which significantly expands the sealing surface and takes into account both the sealing and limiting effects.

[0049] Furthermore, in some embodiments, the top end of the raised portion 3 is folded toward the center axis of the mounting opening 4 to form a second flange 32, and the second flange 32 abuts against the bottom wall 12 of the accommodating groove 11, further increasing the sealing surface, and the contact surface between the second flange 32 and the bottom wall 12 is larger, which helps to improve the installation stability of the cover body 1 and improve the impact of the raised portion 3 on the cover body 1 during installation.

[0050] See also Figures 8 to 10Furthermore, in order to better play a limiting role and expand the sealing surface, in one embodiment, the raised portion 3 has a height H protruding from the mounting body, 2mm≤H≤10mm. For example, H can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm and a value between any two of the above values. Controlling the height within this range helps to improve the limiting effect of the raised portion 3 while saving materials and reducing costs.

[0051] The raised portion 3 is provided protruding from the surface of the mounting body and can be a raised structure of any shape, such as a cone, column, plate, or sphere. The raised portion 3 can be provided as one or more. For example, a plate-shaped raised portion 3 can be provided, and the raised portion 3 is provided at any position beside the mounting opening 4. Alternatively, multiple raised portions 3 can be provided, and the multiple raised portions 3 can be provided with or without intervals along the circumference of the mounting opening 4. In this way, the raised portion 3 can be uniformly contacted with the sidewalls of the receiving groove 11, not only obtaining more sealing surfaces, but also better sealing the sealing areas around the mounting opening 4. In one embodiment, the raised portion 3 is an annular protrusion provided around the mounting opening 4. In this way, not only a large sealing surface is provided, but also better protection is provided for the joints between the first flange 14 and the mounting body. In addition, the annular structure design also helps to improve the strength of the raised portion 3, avoid deformation, better support the cover body 1, and ensure the sealing effect between the raised portion 3 and the cover body 1. Based on this, in some embodiments, the top of the raised portion 3 is further formed with the second flange 32 . The combination of the second flange 32 and the annular protrusion can further enhance the strength of the raised portion 3 and improve its deformation resistance.

[0052] The annular protrusion can be an annular structure of any shape, such as a triangle, square, polygon, circle, quasi-circular or other ring shape, etc. Correspondingly, the receiving groove 11 of the cover body 1 is designed to be a shape that is compatible with the annular protrusion, so that when the cover body 1 is covered on the mounting port 4, the annular protrusion can be inserted into the receiving groove 11, and the outer peripheral wall of the annular protrusion can fit tightly with the side wall of the receiving groove 11.

[0053] In some embodiments, the annular protrusion is configured as a square ring formed by four first side walls 31, and the accommodating groove 11 is configured as a square groove formed by four second side walls 13a. The four first side walls 31 correspond to the four second side walls 13a one by one and are arranged to fit each other.

[0054] Furthermore, in one embodiment, if Figure 7 、 Figure 8As shown, in the annular protrusion, two adjacent first side walls 31 among the four first side walls 31 are connected by a circular arc transition to form an arc portion 5; the square groove has four second side walls 13a, and two adjacent second side walls 13a among the four second side walls 13a are connected by a circular arc transition to form a matching portion 16. The matching portion 16 matches the arc portion 5. When the cover body 1 is placed on the installation opening 4, the arc portion 5 can match the matching portion 16. The design of the arc portion 5 can play a role in indicating the installation direction and positioning when the cover body 1 is installed, thereby avoiding installation in the wrong direction. In addition, the large radius and the annular structure make the arc portion 5 less likely to deform. Even if the installation body is deformed by external force, it will not affect the shape of the annular protrusion and the arc portion 5, thereby avoiding interference with the anti-misinstallation function of the arc portion 5 and the matching between the annular protrusion and the receiving groove 11.

[0055] In some embodiments, the cover body 1 has a top 15 corresponding to the mounting opening 4 and facing away from the mounting opening 4. The top 15 of the cover body 1 is designed as an inclined surface, for example, designed to be inclined in a first direction away from the mounting opening 4. It is understood that the first direction depends on the specific installation orientation of the junction box 100 and can be any direction that is convenient for drainage. For example, when the plane where the mounting opening 4 is located is a vertical plane that is vertical or approximately vertical to the horizontal plane, the first direction can be a top-down direction. In this way, not only can drainage be achieved by means of the inclined surface, but the sealing surface can be maximized while the surface of the outer surface of the cover body 1 that is located above and parallel to the horizontal plane can be appropriately reduced in area, thereby reducing the amount of water attached to the surface. When the plane where the mounting opening 4 is located is parallel or approximately parallel to the horizontal plane, the first direction can be any direction parallel to the horizontal plane, as long as the top surface of the cover body 1 is inclined relative to the horizontal plane.

[0056] Correspondingly, the height H of the protrusion 3 shows a gradual trend in the first direction. When the top 15 of the cover body 1 tilts away from the installation opening 4 along the first direction, H gradually increases in the first direction.

[0057] The present application also provides a refrigeration device 1000, such as a freezer, refrigerator, etc. The refrigeration device 1000 includes the above-mentioned junction box mounting structure. The specific structure of the junction box mounting structure is referred to in the above-mentioned embodiment. Since the refrigeration device 1000 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described in detail here. Among them, the junction box mounting structure includes a mounting body and a junction box 100, the mounting body has a mounting opening that abuts against the side portion of the mounting body near the mounting opening 4, and at least a portion of the cover 1 overlaps with the raised portion 3; the junction box 100 includes a cover 1 covering the mounting opening and a terminal 2 mounted on the cover 1, the cover 1 covering the outside of the raised portion 3, at least a portion of the cover 1 abuts against the side portion 6 of the mounting body near the mounting opening 4, and at least a portion of the cover 1 overlaps with the raised portion 3.

[0058] The refrigeration device 1000 adopts the junction box installation structure described above, which helps to improve the installation sealing and installation accuracy of its junction box 100 and avoids foam leakage during the foaming process, which affects the wiring.

[0059] Specifically, in one embodiment, the refrigeration device 1000 includes a refrigerator liner 200 and a junction box 100. The refrigerator liner 200 is the main structural component of the refrigeration device 1000 and primarily serves as an internal container for storing food and other items. It has insulating and sealing functions to keep cold air circulating inside while preventing external heat from entering. The refrigerator liner 200 can be made of metal or plastic. In the refrigeration device 1000, the junction box 100 is mounted on the refrigerator liner 200. The refrigerator liner 200 constitutes the mounting body of the junction box mounting structure, and the junction box 100 constitutes the junction box 100 of the junction box mounting structure.

[0060] In one embodiment, the cover 1 has a top 15 corresponding to and facing away from the mounting opening 4. The top 15 of the cover 1 is designed as an inclined surface. Thus, when condensation or water leakage occurs in the refrigeration device 1000, water adhering to the cover 1 can be quickly drained along the inclined surface, avoiding impact on the terminal 2. In some embodiments, the top 15 is specifically designed to be inclined in a top-down direction away from the mounting opening 4. This allows water on the top 15 of the cover 1 to drain along the inclined surface. The upper surface of the cover 1 is smaller, helping to reduce the amount of water adhering to it. The lower surface of the cover 1 is relatively larger, thereby increasing the sealing surface between the cover 1 and the raised portion 3. It should be understood that the terms "upper" and "lower" herein merely represent the orientation of the refrigeration device 1000 when in use. This description of the structure of the cover 1 uses the components in this orientation as an example.

[0061] Correspondingly, the shape of the raised portion 3 is adapted to the cover body 1, and the height H of the raised portion 3 gradually increases from top to bottom. In this way, the sealing surface between the cover body 1 and the raised portion 3 can be increased while ensuring that the cover body 1 can drain water smoothly and reduce the amount of water adhesion.

[0062] In the above embodiments, the descriptions of each embodiment have their own emphasis. For parts not described in detail in a particular embodiment, please refer to the relevant descriptions of other embodiments. In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features.

[0063] The above is a detailed introduction to the technical solutions provided in the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for those skilled in the art, based on the ideas of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
