Description

Technical Field

[0001] This utility model relates to the field of door hinge structure technology, specifically a concealable wire-passing door hinge structure. Background Technology

[0002] Current wine cabinet / refrigerator products require the use of electronic control modules such as lights, display control modules, and heating films on the door. These modules automatically illuminate the interior storage space when the door is opened and immediately turn off when closed, avoiding unnecessary energy consumption and making item retrieval more convenient and efficient. For high-end wine cabinets, some lights also feature adjustable color temperature designs. Cool light mode highlights the refreshing feel of beverages, while warm light mode enhances the rich atmosphere of red wine, further improving the user's sensory experience. When using electronic control modules such as lights, display control modules, and heating films on the door, the wiring harness needs to run from one side of the cabinet to the other side of the door.

[0003] In existing technologies, common wiring solutions involve connecting the wiring terminals at the top or bottom hinge of the cabinet, then concealing the wiring harness and terminals with a hinge cover. This approach has the following drawbacks for current wine cabinets / refrigerators: Firstly, placing the wiring at the top hinge makes the hinge cover visible, resulting in an unsightly appearance. Secondly, gaps between the hinge and the door due to manufacturing and assembly tolerances can affect aesthetics. Thirdly, such products are unsuitable for embedded installations, limiting their applicability. Fourthly, placing the wiring at the bottom hinge increases the risk of water flow at the bottom, potentially causing short circuits at the wiring harness terminals. Finally, with terminals at the bottom, maintenance requires tilting the cabinet, hindering disassembly and repair. Therefore, a concealable wiring hinge structure is proposed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to the following: Figures 1-9 This utility model provides a technical solution: a concealable cable-passing hinge structure, including a housing 1, a cable-passing hinge component 2, and a wire structure 3 for power supply. The cable-passing hinge component 2 includes a pre-embedded cable box 201 embedded inside the housing 1 and a hinge 202 mounted on the housing 1 by screws. A door hinge sleeve 203 is installed at the center of the hinge 202, and a door hinge cover 205 is installed on the outer surface of the hinge 202 by screws. The wire structure 3 includes a first terminal 301, a second terminal 302, a first wire harness 303, and a second wire harness 304. The first wire harness 303 is electrically connected to the wire harness in the pre-embedded junction box 201 through the first terminal 301, and the second wire harness 304 is electrically connected to the wire harness on the door of the enclosure 1 through the second terminal 302. The wire-passing door hinge component 2 also includes a bracket 204. The bracket 204 has a connecting shaft adapted to the door hinge sleeve 203 inside. The bracket 204 has a wire outlet hole for hiding the second wire harness 304 and the second terminal 302 inside. A decorative cover 206 is installed on the outer surface of the bracket 204 by screws.

[0027] The pre-embedded junction box 201 is pre-embedded inside the housing 1. First, the first terminal 301 is connected to the first wire harness 303, and the first wire harness 303 is passed through the interior of the pre-embedded junction box 201. The hinge 202 is fixed to the housing 1 with screws. The door hinge sleeve 203 is installed on the hinge 202, and the first wire harness 303 is passed through the through slot of the hinge 202. Then, the door hinge cover 205 is installed, and the door hinge cover 205 is installed on the hinge 202 with screws. The door end... The second wiring harness 304 passes through the hole in the bracket 204 and is fixed to the door body by screws. The connecting shaft of the bracket 204 is inserted into the door hinge sleeve 203 of the hinge 202. Then, the second wiring harness 304 is connected to the second terminal 302 and the second wiring harness 304 and the second terminal 302 are hidden below the wire outlet hole of the bracket 204. Finally, the decorative cover 206 is fixed to the bracket 204 by screws, thus completing the assembly of the device.

[0028] Among them, the box 1 is any box-type product that requires the installation of an electronic control module on the door. Regardless of whether the installation design of the box 1 is embedded or freestanding, the wire-passing door hinge structure can be used.

[0029] Furthermore, a stepped surface is provided at the contact position between the hinge 202 and the door hinge sleeve 203. Specifically, the purpose of providing the stepped surface is to prevent the hinge 202 from directly contacting the large hardware surface of the bracket seat 204 due to the failure of the flange surface of the door hinge sleeve 203, which would cause abnormal noise.

[0030] Furthermore, a blind hole is provided at the lateral center of the hinge 202. The door hinge sleeve 203 cooperates with the hinge 202 through the blind hole. Specifically, the purpose of setting the blind hole is to prevent the door hinge sleeve 203 from falling directly after the flange surface fails, causing the hardware shaft of the bracket seat 204 to rub directly against the hole of the hinge 202, thereby causing abnormal noise when the door is opened and closed.

[0031] Furthermore, the upper end of the hinge 202 is provided with an L-shaped guide positioning groove, and the hinge cover 205 is provided with a positioning protrusion that corresponds to the L-shaped guide positioning groove. Specifically, the upper end of the hinge 202 is designed with an L-shaped guide positioning groove. When installing the hinge cover 205, the positioning protrusion on the hinge cover 205 can be directly pushed into the L-shaped guide positioning groove, thereby facilitating the installation of the hinge cover 205 and the hinge 202 and making it easier to disassemble and repair the wiring harness later.

[0032] Furthermore, the hinge 202 has a groove at its bottom, and the hinge cover 205 has a rib at its bottom that matches the groove. Specifically, after the hinge cover 205 is installed, its bottom rib can withstand the reverse force. That is, if an external force pries the hinge cover 205 from the top, the bottom rib of the hinge cover 205 will be forced upward to hold the hinge 202 in place, ensuring that the hinge cover 205 and the hinge 202 do not loosen.

[0033] Furthermore, the outer surface of the bracket 204 is provided with an oblong hole. Specifically, by providing an oblong hole on the bracket 204, it is convenient to install the bracket 204 on the door, and the door of the cabinet 1 can be adjusted. From the perspective of installation and debugging flexibility, the oblong hole can solve the assembly problem caused by dimensional errors. The oblong hole can also improve the versatility and adaptability of the bracket 204. Different models of doors may require adjustment of the installation position of the bracket 204 due to differences in size and specifications. The adjustable range of the oblong hole allows it to adapt to various door structures without redesigning the hole position.

[0034] Working Principle: In use, the pre-embedded junction box 201 is pre-embedded inside the housing 1. First, the first terminal 301 is connected to the first wire harness 303, and the first wire harness 303 is passed through the interior of the pre-embedded junction box 201. The hinge 202 is fixed to the housing 1 with screws. The door hinge sleeve 203 is installed on the hinge 202, and the first wire harness 303 is passed through the through groove of the hinge 202. Then, the door hinge cover 205 is installed and screwed onto the hinge 202. The second wire harness 304 at the door end passes through the hole in the bracket 204, and the bracket 204 is fixed to the door with screws. The connecting shaft of the bracket 204 is inserted into the door hinge sleeve 203 of the hinge 202. Then, the second wiring harness 304 is connected to the second terminal block 302, and the second wiring harness 304 and the second terminal block 302 are hidden below the cable outlet hole of the bracket 204. The decorative cover 206 is fixed to the bracket 204 with screws, thus completing the assembly of the device. When the cabinet door is opened, the hinge 202 and the bracket 204 achieve a self-limiting function. Regardless of whether the cabinet 1 is recessed or freestanding, this cable-passing door hinge structure can be used, and the door hinge can be hidden, improving the overall aesthetics of the product. The door hinge and the bracket 204 have a self-limiting function. The hinge 202 is easy to install and can be easily disassembled and maintained. After the terminal wiring harness is connected, it can be hidden inside the door, which can effectively protect the terminal from short circuits caused by moisture.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
