There is no direct wiring on the hinge device of the present invention, but the second wiring harness 9 led out of the box body 1 and the first wiring harness 5 introduced into the door body 2 are connected by plugging the first wiring terminal 6 and the second wiring terminal 8, so as to avoid the problem of wear and breakage of the wiring on the hinge, which leads to failure of signal transmission and power supply between the box body 1 and the door body 2. Furthermore, when the door body 2 needs to be removed, the door body 2 can be easily removed by only moving the docking piece 7 to a state where the first terminal 6 and the second terminal 8 are separated, and no special tools are required, thereby simplifying the process of removing the door body 2 and reducing the difficulty of removing the door body 2.

[0023] The docking piece 7 of the hinge device of the present invention can be detachably connected to the hinge component 4 in a variety of ways, such as sliding connection, flip connection, etc. Specifically, the docking piece 7 has a connection position for docking the second terminal 8 with the first terminal 6, and a separation position for separating the second terminal 8 from the first terminal 6. When the first terminal 6 and the second terminal 8 are plugged in, the first wiring harness 5 and the second wiring harness 9 are electrically connected, thereby realizing signal transmission and electrical connection between the box body 1 and the door body 2. When the door body 2 needs to be disassembled, the docking piece 7 needs to be switched from the connection position to the separation position first, so that the second terminal 8 is separated from the first terminal 6, and the door body 2 can be easily disassembled.

[0024] Furthermore, the wiring structure includes a wiring hole 41 penetrating the hinge part 4 in the up-down direction, a first wiring groove 42 recessed in the upper end surface of the hinge part 4 and connected to the wiring hole 41, the first wiring terminal 6 is embedded in the first wiring groove 42, and the first wiring harness 5 connected to the first wiring terminal 6 is introduced into the door body 2 through the first wiring groove 42 and the wiring hole 41 in sequence. The present invention achieves the fixation of the first wiring harness 5 by accommodating the first wiring harness 5 in the first wiring groove 42 and the wiring hole 41, and ensures the connection reliability of the first wiring harness 5 and the first wiring terminal 6. At the same time, the present invention introduces the first wiring harness 5 into the door body 2 through the wiring hole 41 penetrating the hinge part 4, and when the door body 2 rotates, it can effectively protect the first wiring harness 5 from being worn, thereby ensuring the power supply and signal transmission between the box body 1 and the door body 2.

[0025] It can be understood that the first wiring terminal 6 is embedded in the first wiring groove 42 , and the plug-in connection surface of the first wiring terminal 6 is placed upward, so as to facilitate plugging with the second wiring terminal 8 .

[0026] Furthermore, the wiring structure also includes a terminal groove 71 penetrating the docking member 7 in the up-down direction, and a second wiring groove 72 recessed in the upper end surface of the docking member 7, the second wiring groove 72 is connected to the terminal groove 71, the second wiring terminal 8 is arranged in the terminal groove 71, and the second wiring harness 9 connected to the second wiring terminal 8 is located in the second wiring groove 72. The terminal groove 71 arranged on the docking member 7 is a through groove, and when the second wiring terminal 8 is located in the terminal groove 71, the plug-in connection surface of the second wiring terminal 8 protrudes from the lower end of the docking member 7, so that when the docking member 7 is in the connection position, the plug-in connection surface of the second wiring terminal 8 is connected to the plug-in connection surface of the first wiring terminal 6, so that the first wiring terminal 6 and the second wiring terminal 8 are plugged and fixed, thereby realizing the electrical connection between the first wiring harness 5 and the second wiring harness 9. In addition, the present invention fixes the second wiring harness 9 in the second wiring groove 72, ensuring the reliability of the connection between the second wiring harness 9 and the second wiring terminal 8.

[0027] In a specific embodiment of the present invention, the hinge component 4 is divided into two parts, which is more convenient for processing the hinge device. Specifically, the hinge component 4 includes a fixing seat 43 fixedly connected to the box body 1, a hinge plate 44 detachably connected to the fixing seat 43, and the wiring hole 41 and the first wiring groove 42 are arranged on the hinge plate 44. When the door body 2 needs to be disassembled, the docking member 7 needs to be switched from the connection position to the separation position to separate the second wiring terminal 8 from the first wiring terminal 6, and then the hinge plate 44 is removed from the fixing seat 43, and the door body 2 can be easily disassembled.

[0028] It can be understood that one side of the hinge plate 44 is detachably connected to the fixing seat 43, and the other side is located on the upper side of the upper end of the door body 2, for example, it can be suspended on the upper end of the door body 2, and the wiring hole 41 is connected to the wiring channel inside the door body 2.

[0029] Furthermore, the fixing seat 43 includes a bottom wall 431 fixedly connected to the box body 1; the hinge plate 44 includes a first connecting section 441 connected to the bottom wall 431 and a second connecting section 442 provided with the wiring hole 41, and the first connecting section 441 and the second connecting section 442 form a first step structure that abuts against the end surface of the bottom wall 431, which facilitates the positioning of the hinge plate 44 and the fixing seat 43 during installation and realizes quick installation.

[0030] Furthermore, the wiring structure also includes a threaded hole arranged on the bottom wall 431, a connecting through hole arranged on the first connecting section 441 and docking with the threaded hole, and a fastener 10 connected to the threaded hole and the connecting through hole, and the fastener 10 is used to achieve quick disassembly between the hinge plate 44 and the fixing seat 43.

[0031] Further, the fixing seat 43 includes two side walls 432 symmetrically arranged on both sides of the bottom wall 431 along the first direction, and a groove 433 recessed inwardly from the side of the side wall 432 close to the bottom wall 431, and the groove 433 is located on the upper side of the hinge plate 44, and the two opposite sides of the docking member 7 along the first direction are respectively slidably connected in the corresponding grooves 433, and the docking member 7 is slidably connected to the fixing seat 43, so as to facilitate the adjustment of the position of the docking member 7, that is, to facilitate the switching of the first wiring terminal 6 and the second wiring terminal 8 between the plug-in state and the separated state. It can be understood that the first direction can be the left-right direction of the refrigeration equipment.

[0032] Specifically, the docking member 7 slides toward the hinge plate 44 to a preset position or an extreme position, the docking member 7 is in the connection position, and the second terminal 8 is docked with the first terminal 6. When the docking member 7 slides away from the hinge plate 44 until the second terminal 8 is separated from the first terminal 6, the docking member 7 switches from the connection position to the separation position, so that the door body 2 of the refrigeration equipment can be easily disassembled. It can be understood that when the docking member 7 is in the connection position, the docking member 7 covers the first connection section 441 of the hinge plate 44, and the position of the groove 433 can also be set so that when the docking member 7 is in the connection position, the docking member 7 presses the hinge plate 44, so that the first terminal 6 and the second terminal 8 are connected more reliably.

[0033] In a specific embodiment, the side walls 432 on opposite sides of the docking member 7 along the first direction are provided with spring positioning columns, the bottom of the groove 433 on the side close to the hinge plate 44 is provided with a first positioning groove that matches the spring positioning column, and the bottom of the groove 433 on the side away from the hinge plate 44 is provided with a second positioning groove that matches the spring positioning column. When the spring positioning column is located in the first positioning groove, the first wiring terminal 6 and the second wiring terminal 8 are plugged in, and when the spring positioning column is located in the second positioning groove, the first wiring terminal 6 and the second wiring terminal 8 are separated. Due to the elastic force of the spring positioning column, when the spring positioning column matches the first positioning groove or the second positioning groove, the spring positioning column abuts against the corresponding groove bottom, so that the docking member 7 is kept in the corresponding position.

[0034] Furthermore, the docking member 7 includes a sliding section 73 movably connected to the groove 433 and a limiting section 74 located on the side of the sliding section 73 away from the hinge plate 44. When the spring positioning column is located in the positioning groove 12, the limiting section 74 and the sliding section 73 form a second step structure abutting against the side wall 432, so as to facilitate the rapid positioning of the hinge plate 44 and the fixing seat 43 to the docking position of the spring positioning column and the positioning groove 12 when installing.
