Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, for example, to a hinge mechanism and a refrigerator. Background Art

[0002] The current power supply method for the door body is mainly to set the hinge shaft as a hollow shaft, pass the wire through the through hole of the hinge shaft of the box body, then enter the shaft sleeve of the door body, and finally connect the electrical components of the door body. While the door body is rotating, the wire harness is deformed and bent in the shaft sleeve or the door body, reducing the service life of the harness, thereby reducing the service life of the power supply hinge. When the service life of the harness reaches the upper limit, the harness will break, causing the door body to lose power, and then the power supply fails. Therefore, how to increase the service life of the power supply hinge and avoid accidental power failures during power supply needs to be solved urgently.

The hinge shaft 110 is passed from the side of the first hinge hole 312 to the inside of the second hinge hole 512, and the second hinge seat 50 can rotate relative to the hinge shaft 110. During the relative rotation of the first hinge seat 30 and the second hinge seat 50, the transmitting structure 40 and the receiving structure 60 can achieve different conduction states.

[0054] In the hinge mechanism 1 provided by the embodiment of the present disclosure, during the relative rotation of the first hinge seat 30 and the second hinge seat 50, the transmitting structure 40 and the receiving structure 60 can achieve different conduction states. Among them, the different conduction states include the power-on state. Compared with the related art, the present application realizes current conduction through the transmitting structure 40 and the receiving structure 60, avoiding the structural design of inserting the wire into the hinge shaft 110, so that the two ends of the wire are respectively located in the door body and the box body. Therefore, by using the hinge mechanism 1 to be arranged between the door body and the box body, in the process of rotating the door body and the box body, the wire harness will not be deformed and the service life of the harness will not be reduced, thereby improving the service life of the hinge mechanism 1 and reducing the probability of accidental power failure during power supply due to the breakage of the harness.

[0055] Combination Figures 1 to 6 As shown, the second hinge assembly 20 includes a first hinge seat 30 and a second hinge seat 50 which are rotatably connected. The first hinge seat 30 is provided with a first hinge hole 312, and the second hinge seat 50 is provided with a second hinge hole 512. The first hinge hole 312 and the second hinge hole 512 are coaxially arranged. The first hinge assembly 10 is passed from the first hinge hole 312 side to the second hinge hole 512 to form a sleeve structure between the hinge shaft 110, the first hinge seat 30 and the second hinge seat 50, thereby realizing the connection setting between the first hinge assembly 10 and the second hinge assembly 20, and improving the connection stability between the first hinge assembly 10 and the second hinge assembly 20.

[0056] In addition, the second hinge seat 50 can rotate relative to the hinge shaft 110. When the hinge mechanism 1 is installed between the box body and the door body, the second hinge seat 50 is connected to one of the box body and the door body, and the first hinge assembly 10 is connected to the other of the box body and the door body. The second hinge seat 50 can rotate relative to the hinge shaft 110, so that the second hinge seat 50 can rotate relative to the first hinge assembly 10, thereby ensuring the rotation connection between the box body and the door body.

[0057] Optionally, the first hinge seat 30 is provided with a first conductive hole, and the wire is passed through the first conductive hole to connect with the transmitting structure 40. The second hinge seat 50 is provided with a second conductive hole, and the wire is passed through the second conductive hole to connect with the receiving structure 60. Among them, the first hinge hole 312 and the first conductive hole are distributed in the first hinge seat 30 at intervals, and the axes of the first hinge hole 312 and the first conductive hole are parallel to each other. The second hinge hole 512 and the second conductive hole are distributed in the second hinge seat 50 at intervals, and the axes of the second hinge hole 512 and the second conductive hole are parallel to each other.

[0058] In this embodiment, a first conductive hole is opened in the first hinge seat 30 and a second conductive hole is opened in the second hinge seat 50, so that the wire can be passed through the first conductive hole to connect with the transmitting structure 40, and the wire can be passed through the second conductive hole to connect with the receiving structure 60, thereby realizing the connection between the transmitting structure 40 and the receiving structure 60 and the wires, so that an external power source can supply power to the transmitting structure 40 and then transmit it to the receiving structure 60.

[0059] Optionally, the first hinge seat 30 is provided with a first conductor, the output end of the first conductor is connected to the transmitting structure 40, and the input end of the first conductor is connected to the wire. The second hinge seat 50 is provided with a second conductor, the input end of the second conductor is connected to the receiving structure 60, and the output end of the second conductor is connected to the wire. The first hinge hole 312 is located at the first hinge seat 30 with a spacing from the first conductor, and the axis of the first hinge hole 312 and the first conductor are parallel to each other. The second hinge hole 512 is located at the second hinge seat 50 with a spacing from the second conductor, and the axis of the second hinge hole 512 and the second conductor are parallel to each other.

[0060] In this embodiment, a first conductor is arranged on the first hinge seat 30, a second conductor is arranged on the second hinge seat 50, and the output end of the first conductor is connected to the transmitting structure 40, the input end of the first conductor is connected to the wire, the input end of the second conductor is connected to the receiving structure 60, and the output end of the second conductor is connected to the wire, so as to realize the connection between the transmitting structure 40 and the receiving structure 60 and the wire, so that an external power supply can power the transmitting structure 40 and then transmit it to the receiving structure 60.

[0061] Optionally, combined Figures 1 to 4 As shown, the second hinge assembly 20 also includes a first shell 70. The first shell 70 defines a launch chamber 710 and a receiving chamber 720, and the launch chamber 710 and the receiving chamber 720 are coaxial and interlinked. The first hinge seat 30 is fixedly or movably disposed in the launch chamber 710, and correspondingly, the second hinge seat 50 is movably or fixedly disposed in the receiving chamber 720 to achieve relative rotation between the first hinge seat 30 and the second hinge seat 50. Among them, the first end face 314 of the first hinge seat 30 is arranged opposite to the second end face 514 of the second hinge seat 50. The launch structure 40 is located at the first end face 314 of the first hinge seat 30, and the receiving structure 60 is located at the second end face 514 of the second hinge seat 50, and the launch structure 40 is slidably connected to the receiving structure 60.

[0062] In this embodiment, the second hinge assembly 20 includes a first shell 70, a first hinge seat 30, a second hinge seat 50, a launch structure 40 and a receiving structure 60. The launch structure 40 is arranged on the first hinge seat 30, and the receiving structure 60 is arranged on the second hinge seat 50. The first shell 70 defines a launch cavity 710 and a receiving cavity 720, and the first hinge seat 30 and the second hinge seat 50 are respectively arranged in the launch cavity 710 and the receiving cavity 720. By arranging the first hinge seat 30 and the second hinge seat 50 in the launch cavity 710 and the receiving cavity 720, respectively, the first hinge seat 30 and the second hinge seat 50 are arranged in the first shell 70 to protect the launch structure 40 and the receiving structure 60, thereby improving the service life of the launch structure 40 and the receiving structure 60, and further improving the service life of the hinge mechanism 1. The launch cavity 710 and the receiving cavity 720 are connected to facilitate power on or off between the launch structure 40 and the receiving structure 60. In addition, by providing the first shell 70 , leakage of electricity between the transmitting structure 40 and the receiving structure 60 during the power-on process can be avoided, thereby preventing economic losses or health hazards to users.

[0063] Optionally, combined Figures 7 to 11 As shown, the receiving structure 60 includes a receiving slot 610. The receiving slot 610 is extended around the circumference of the second hinge hole 512 and is arranged on the second end surface 514 of the second hinge seat 50, and the receiving slot 610 includes a conductive segment 612 and a resistive segment 614, and the resistance of the resistive segment 614 is greater than the resistance of the conductive segment 612. During the relative rotation of the first hinge seat 30 and the second hinge seat 50, the transmitting structure 40 is slidably connected with the conductive segment 612 and / or the resistive segment 614 of the receiving structure 60 to achieve different conduction states.

[0064] In this embodiment, the receiving slot 610 is extended around the circumference of the second hinge hole 512 and is disposed on the second end surface 514 of the second hinge seat 50. During the relative rotation of the first hinge seat 30 and the second hinge seat 50, the emitting structure 40 moves along the extension direction of the receiving slot 610, so that relative movement occurs between the emitting structure 40 and the receiving structure 60. The receiving slot 610 includes a conductive segment 612 and a resistive segment 614, and the resistance of the resistive segment 614 is greater than the resistance of the conductive segment 612. During the movement of the emitting structure 40 along the extension direction of the receiving slot 610, the emitting structure 40 is slidably connected with the conductive segment 612 and / or the resistive segment 614 of the receiving structure 60 to achieve switching between different conduction states.

[0065] Furthermore, a low-resistance material is laid in the conductive segment 612 , and an insulating material is laid in the resistive segment 614 , so that the resistance of the resistive segment 614 is greater than the resistance of the conductive segment 612 .

[0066] In this embodiment, a low-resistance material is laid in the conductive segment 612. For example, the low-resistance material is copper, aluminum, silver or graphene. Since the conductive segment 612 has a low resistance value and good conductivity, the resistance of the conductive segment 612 can be ignored during the process of the current flowing through the transmitting structure 40 through the conductive segment 612, so that the current between the transmitting structure 40 and the receiving structure 60 is stably conducted, and the power consumption is small, thereby improving the energy-saving effect of the hinge mechanism 1. An insulating material is laid in the resistance segment 614. For example, the insulating material is rubber, plastic, ceramic, glass or mica. Since the second conductive segment 612 has a good insulating effect, during the process of the current flowing through the transmitting structure 40 through the second conductive segment 612, the current between the transmitting structure 40 and the receiving structure 60 is cut off, and the hinge mechanism 1 is powered off.

[0067] During the relative rotation of the first hinge seat 30 and the second hinge seat 50, the transmitting structure 40 is slidably connected with the conductive segment 612 and / or the resistive segment 614 of the receiving structure 60, so that the hinge mechanism 1 can switch between the power-on and power-off states. Specifically, the transmitting structure 40 is slidably connected with the conductive segment 612 of the receiving structure 60, and the hinge mechanism 1 is powered on. As the first hinge seat 30 and the second hinge seat 50 rotate relative to each other, the transmitting structure 40 is slidably connected with the second conductive segment 612 of the receiving structure 60, and the hinge mechanism 1 is powered off.

[0068] Optionally, combined Figures 10 to 12 As shown, the transmitting structure 40 includes a transmitting terminal 410. The transmitting terminal 410 is disposed on the first end surface 314 of the first hinge seat 30 and is slidably connected to the receiving slot 610. During the relative rotation of the first hinge seat 30 and the second hinge seat 50, the transmitting end of the transmitting terminal 410 is slidably connected to the conductive segment 612 and / or the resistive segment 614 to achieve different conduction states.

[0069] In this embodiment, during the relative rotation of the first hinge seat 30 and the second hinge seat 50, the transmitting end of the transmitting terminal 410 is slidably connected to the conductive segment 612 and / or the resistive segment 614, so that the hinge mechanism 1 can switch between the power-on and power-off states to achieve different conduction states. Specifically, the transmitting end of the transmitting terminal 410 is slidably connected to the conductive segment 612 of the receiving structure 60, and the hinge mechanism 1 is powered on. As the first hinge seat 30 and the second hinge seat 50 rotate relative to each other, the transmitting end of the transmitting terminal 410 is slidably connected to the second conductive segment 612 of the receiving structure 60, and the hinge mechanism 1 is powered off.

[0070] Optionally, combined Fig.11 and Fig.12As shown, the transmitting terminal 410 includes an elastic pin bracket 412 and an elastic pin 418. The elastic pin bracket 412 includes a connecting portion 414 and an extending portion 416, wherein the extending portion 416 is connected to one end of the connecting portion 414, and the other end of the connecting portion 414 is connected to the first hinge seat 30, and the extending portion 416 defines a first cavity. The elastic pin 418 is disposed in the first cavity, and a portion of the elastic pin 418 protrudes from the first cavity and is slidably connected to the receiving slot 610.

[0071] In this embodiment, the transmitting terminal 410 is fixedly arranged on the first hinge seat 30 by connecting the connecting portion 414 with the first hinge seat 30. The spring pin 418 is arranged in the first cavity of the extension portion 416, and part of the spring pin 418 protrudes from the first cavity and is slidably connected with the receiving slot 610 to realize the sliding connection between the transmitting terminal 410 and the receiving slot 610, thereby realizing the rotation connection between the transmitting structure 40 and the receiving structure 60. In addition, the transmitting terminal 410 is made of metal, so that the transmitting terminal 410 has good wear resistance and conductivity, thereby improving the conductive effect between the transmitting structure 40 and the receiving structure 60 and the service life of the hinge mechanism 1. Exemplarily, the metal includes copper or aluminum.

[0072] Optionally, combined Fig.12 As shown, the spring pin 418 includes a second housing 420, a spring 424, a gasket 426 and a ball 428. The second housing 420 defines a second cavity 422. Along the direction from the first hinge seat 30 to the second hinge seat 50, the spring 424, the gasket 426 and the ball 428 are sequentially arranged in the second cavity 422, and a portion of the ball 428 protrudes from the second cavity 422 and is slidably connected to the receiving groove 610.

[0073] In this embodiment, the spring 424, the gasket 426 and the ball 428 are sequentially arranged in the second cavity 422 along the direction from the first hinge seat 30 to the second hinge seat 50, and part of the ball 428 protrudes from the second cavity 422 to form the spring pin 418. The spring 424 is used to improve the elasticity of the spring pin 418 and the load bearing capacity of the spring pin 418, thereby reducing the probability of damage to the spring pin 418 and the hinge structure during the assembly of the second hinge assembly 20 or when the hinge mechanism 1 is assembled on a box or door body. The gasket 426 is used to improve the structural stability of the spring pin 418, thereby improving the structural stability of the hinge mechanism 1. The ball 428 is used, and part of the ball 428 protrudes from the second cavity 422, so as to improve the smooth connection and relative movement fluency between the spring pin 418 and the receiving groove 610.

[0074] Optionally, combined Figures 5 to 8As shown, the transmitting structure 40 includes a first transmitting terminal 430 and a second transmitting terminal 440. Along the circumference of the first hinge hole 312, the first transmitting terminal 430 and the second transmitting terminal 440 are spaced apart on the first end surface 314 of the first hinge seat 30, and are slidably connected with the receiving groove 610. In the process of relative rotation between the first hinge seat 30 and the second hinge seat 50, the first transmitting terminal 430 is slidably connected with one of the conductive segment 612 and the resistive segment 614, and the second transmitting terminal 440 is slidably connected with the other of the conductive segment 612 and the resistive segment 614 to achieve different conduction states.

[0075] Furthermore, a low-resistance material is laid in the conductive segment 612 , and a medium-resistance material is laid in the resistive segment 614 . The resistance of the resistive segment 614 is greater than the resistance of the conductive segment 612 .

[0076] Among them, the resistance of low-resistance material is less than the resistance of medium-resistance material and less than the resistance of insulating material.

[0077] Exemplarily, the low-resistance material is copper, aluminum, silver or graphene, etc. The medium-resistance material is a carbon film, a metal film, a metal oxide film or a cement (ceramic) wire-wound semiconductor, etc.

[0078] In the traditional technology, when the refrigerator door is opened and closed, a mechanical switch or a Hall switch is used to read the door opening angle to monitor the door opening and closing status. However, this door opening angle detection method can only roughly obtain the door opening and closing status, and the door opening angle detection accuracy is low.

[0079] In this embodiment, the resistance value of the resistance segment 614 is higher than that of the conductive segment 612. In the relative rotation process between the first hinge seat 30 and the second hinge seat 50, the first transmitting terminal 430 is slidably connected to one of the conductive segment 612 and the resistance segment 614, and the second transmitting terminal 440 is slidably connected to the other of the conductive segment 612 and the resistance segment 614. With the relative rotation between the first hinge seat 30 and the second hinge seat 50, the length of the resistance segment 614 between the first transmitting terminal 430 and the second transmitting terminal 440 changes, and then the resistance value between the first transmitting terminal 430 and the second transmitting terminal 440 changes. By using the change in the resistance value between the first transmitting terminal 430 and the second transmitting terminal 440, the rotation angle between the first hinge seat 30 and the second hinge seat 50 can be achieved. In addition, when the hinge mechanism 1 is set between the door body and the box body, the door opening angle detection is realized in the process of rotating the door body and the box body, and the door opening angle detection accuracy is improved compared with the traditional technology.

[0080] Specifically, during the relative rotation of the first hinge seat 30 and the second hinge seat 50, the first transmitting terminal 430 is slidably connected to one of the conductive segment 612 and the resistive segment 614, and the second transmitting terminal 440 is slidably connected to the other of the conductive segment 612 and the resistive segment 614. The terminal resistance value R between the first transmitting terminal 430 and the second transmitting terminal 440 can be obtained by obtaining the terminal voltage value U and the current value I between the first transmitting terminal 430 and the second transmitting terminal 440, and then using Ohm's law R=U / I. Since the resistance in the conductive segment 612 can be ignored, the terminal resistance value R between the first transmitting terminal 430 and the second transmitting terminal 440 can be equivalent to the resistance value of the resistive segment 614 located between the first transmitting terminal 430 and the second transmitting terminal 440. Since the resistance in the conductive segment 612 is ignored, the total resistance value R0 of the resistive segment 614 is known, and the rotation angle θ between the first hinge seat 30 and the second hinge seat 50 is determined according to the following formula:

[0081]

[0082] When the hinge mechanism 1 provided in this embodiment is installed between the box body and the door body, the rotation angle θ between the first hinge seat 30 and the second hinge seat 50 represents the opening angle of the door body.

[0083] Furthermore, combined with Figure 7 and Figure 8 As shown, the area length of the resistance segment 614 accounts for 1 / 2 of the total area length of the receiving slot 610 .

[0084] In this embodiment, the length of the resistance segment 614 is limited to 1 / 2 of the total length of the receiving slot 610 , so as to achieve stable detection of the rotation angle between the first hinge seat 30 and the second hinge seat 50 .

[0085] Specifically, combined Figure 7 As shown, when the second hinge seat 50 is in the first position, the first contact 618 of the sliding connection between the first transmitting terminal 430 and the receiving slot 610, and the second contact 620 of the sliding connection between the second transmitting terminal 440 and the receiving slot 610 are respectively located at opposite ends of the resistance segment 614. At this time, the terminal resistance value R between the first transmitting terminal 430 and the second transmitting terminal 440 located in the resistance segment 614 is the largest, R = R0, and this is defined as the initial position, then the rotation angle θ between the first hinge seat 30 and the second hinge seat 50 is = 0. Combined with Figure 8As shown, the first hinge seat 30 and the second hinge seat 50 rotate relative to each other. When the first hinge seat 30 and the second hinge seat 50 rotate to the second position, the length of the resistance segment 614 between the first transmitting terminal 430 and the second transmitting terminal 440 decreases, and the terminal resistance value R between the first transmitting terminal 430 and the second transmitting terminal 440 located in the resistance segment 614 decreases. At this time, the rotation angle θ between the first hinge seat 30 and the second hinge seat 50 satisfies:

[0086]

[0087] Furthermore, combined with Figure 7 and Figure 8 As shown, the area length of the conductive segment 612 is smaller than the area length of the resistive segment 614 .

[0088] In this embodiment, the resistance segment 614 is connected with one end of the conductive segment 612, so that the first transmitting terminal 430 and the second transmitting terminal 440 can slide in the resistance segment 614 and the conductive segment 612, so as to achieve stable detection of the rotation angle between the first hinge seat 30 and the second hinge seat 50, and make the current conduction between the transmitting structure 40 and the receiving structure 60 more stable. The length of the region of the conductive segment 612 is smaller than the length of the region of the resistance segment 614, so that a disconnection structure is formed on one side of the conductive segment 612, so that the current flows along the first transmitting terminal 430, the resistance segment 614, and the second transmitting terminal 440. By making the current flow along the first transmitting terminal 430, the resistance segment 614, and the second transmitting terminal 440, the accuracy of determining the terminal resistance value R between the first transmitting terminal 430 and the second transmitting terminal 440 located in the resistance segment 614 according to the terminal voltage value U and the current value I between the first transmitting terminal 430 and the second transmitting terminal 440 is improved.

[0089] Optionally, combined Figures 6 to 8 As shown, the receiving groove 610 is annular, and the receiving groove 610 is coaxially arranged with the second hinge hole 512 .

[0090] In the present embodiment, the second hinge seat 50 includes a second end face 514 and a third end face 516 which are arranged opposite to each other. Extending from the second end face 514 toward the third end face 516, the second hinge seat 50 is formed with a receiving groove 610 on the second end face 514. The receiving groove 610 is annular and is arranged coaxially with the second hinge hole 512.

[0091] Furthermore, combined with Figure 7 and Figure 8As shown, the receiving slot 610 further includes an insulating segment 616, and the insulating segment 616, the conductive segment 612 and the resistor segment 614 are connected in sequence, and the insulating segment 616, the conductive segment 612 and the resistor segment 614 are interconnected. The resistance of the insulating segment 616 is greater than the resistance of the resistor segment 614, and the resistance of the resistor segment 614 is greater than the resistance of the conductive segment 612. During the relative rotation of the first hinge seat 30 and the second hinge seat 50, the first transmitting terminal 430 is slidably connected to one of the insulating segment 616 and the conductive segment 612, and the second transmitting terminal 440 is slidably connected to the resistor segment 614.

[0092] In this embodiment, a low-resistance material is laid in the conductive segment 612, a medium-resistance material is laid in the resistance segment 614, and an insulating material is laid in the insulating segment 616. By limiting the insulating segment 616, the conductive segment 612, and the resistance segment 614 to be connected in sequence, and during the relative rotation of the first hinge seat 30 and the second hinge seat 50, the first transmitting terminal 430 is slidably connected to one of the insulating segment 616 and the conductive segment 612, and the second transmitting terminal 440 is slidably connected to the resistance segment 614, and a disconnection structure is formed on one side of the insulating segment 616, so that the current flows between the first transmitting terminal 430, the resistance segment 614, and the second transmitting terminal 440. By allowing the current to flow between the first transmitting terminal 430, the resistance segment 614, and the second transmitting terminal 440, the reliability of the terminal voltage value U and the current value I between the first transmitting terminal 430 and the second transmitting terminal 440 is improved.

[0093] Optionally, the specific structures of the first transmitting terminal 430 and the second transmitting terminal 440 are the same as those of the transmitting terminal 410 , and are not described again here.

[0094] Optionally, combined Figures 3 to 5 As shown, there are multiple first transmitting terminals 430, and along the direction extending outward from the axis of the first hinge hole 312, multiple first transmitting terminals 430 are arranged on the first end surface 314 of the first hinge seat 30. There are multiple second transmitting terminals 440, and along the direction extending outward from the axis of the first hinge hole 312, multiple second transmitting terminals 440 are arranged at intervals on the first end surface 314 of the first hinge seat 30. There are multiple receiving grooves 610, and along the direction extending outward from the axis of the receiving structure 60, multiple receiving grooves 610 are arranged at intervals on the second end surface 514 of the second hinge seat 50. Among them, multiple first transmitting terminals 430 and multiple second transmitting terminals 440 are arranged in a one-to-one correspondence, and multiple receiving grooves 610 are arranged in a one-to-one correspondence with multiple first transmitting terminals 430 or multiple second transmitting terminals 440.

[0095] In this embodiment, a plurality of first transmitting terminals 430 and a plurality of second transmitting terminals 440 are arranged in one-to-one correspondence, and a plurality of receiving slots 610 are arranged in one-to-one correspondence with a plurality of first transmitting terminals 430 or a plurality of second transmitting terminals 440. By increasing the number of first transmitting terminals 430, second transmitting terminals 440 and receiving slots 610, the structural stability of the hinge mechanism 1 is improved, and the state stability of the hinge mechanism 1 in different conduction states is improved.

[0096] It should be noted that the specific number of the first transmitting terminal 430 , the second transmitting terminal 440 and the receiving slot 610 needs to be specifically set according to the actual device, and is not specifically limited in this application.

[0097] Optionally, combined Figures 3 to 5 As shown, the first hinge seat 30 is further provided with a fixing groove 318. The fixing groove 318 is located at the first end surface 314 of the first hinge seat 30. The transmitting terminal 410 is disposed in the fixing groove 318.

[0098] In this embodiment, the first hinge seat 30 includes a first end face 314 and a fourth end face 316 that are arranged opposite to each other. A fixing groove 318 is formed on the first end face 314 of the first hinge seat 30, extending from the first end face 314 toward the fourth end face 316. The transmitting terminal 410 is arranged in the fixing groove 318, so that the transmitting terminal 410 is fixedly connected to the first hinge seat 30.

[0099] Optionally, combined Figures 10 to 12 As shown, the transmitting structure 40 further includes a disc spring 450. The disc spring 450 is located between the transmitting terminal 410 and the slot wall of the fixing slot 318.

[0100] In this embodiment, a disc spring 450 is provided between the transmitting terminal 410 and the groove wall of the fixing groove 318. The elasticity of the disc spring 450 is utilized to improve the elasticity of the transmitting structure 40, and to improve the load bearing capacity between the transmitting terminal 410 and the groove wall of the fixing groove 318. This further reduces the probability of damage to the hinge structure during the process of assembling the hinge mechanism 1 or when the hinge mechanism 1 is assembled on a box or a door.

[0101] Furthermore, combined with Figures 10 to 12 As shown, there are multiple fixing grooves 318, and multiple fixing grooves 318 are spaced apart on the first end surface 314 of the first hinge seat 30. There are multiple transmitting terminals 410, and multiple transmitting terminals 410 are arranged one-to-one with multiple fixing grooves 318. There are multiple disc springs 450, and multiple disc springs 450 are arranged one-to-one with multiple transmitting terminals 410 and / or multiple fixing grooves 318. There are multiple receiving grooves 610, and multiple receiving grooves 610 are spaced apart on the second end surface 514 of the second hinge seat 50, and multiple receiving grooves 610 are arranged one-to-one with multiple transmitting terminals 410.

[0102] In this embodiment, the number of fixing slots 318, transmitting terminals 410, disc springs 450 and receiving slots 610 is increased to improve the structural stability of the hinge mechanism 1 and the state stability of the hinge mechanism 1 in different conduction states.

[0103] It should be noted that the specific number of the fixing slots 318, the transmitting terminals 410, the disc springs 450 and the receiving slots 610 needs to be set according to the actual equipment and is not specifically limited in this application.

[0104] Optionally, combined Figure 3 and Figure 4 As shown, the second hinge assembly 20 further includes a plurality of bearing balls 80. Along the circumference of the receiving cavity 720, the plurality of bearing balls 80 are spaced between the second hinge seat 50 and the cavity wall of the receiving cavity 720, and are slidably connected with the second hinge seat 50 and the cavity wall of the receiving cavity 720.

[0105] In this embodiment, the second hinge assembly 20 includes a first hinge seat 30 and a second hinge seat 50, the first hinge seat 30 includes a first hinge hole 312, and the second hinge seat 50 includes a second hinge hole 512. The hinge shaft 110 passes through the first hinge hole 312 from the fourth end face 316 toward the first end face 314, so that a portion of the hinge shaft 110 protrudes from the first hinge hole 312 and is located at the first end face 314 of the first hinge seat 30. The portion of the hinge shaft 110 protruding from the first hinge hole 312 passes through the second hinge hole 512 from the second end face 514 toward the third end face 516, and the second hinge seat 50 can rotate relative to the hinge shaft 110. The second hinge seat 50 is disposed in the receiving cavity 720 in the first housing 70, and the second hinge seat 50 can rotate relative to the first housing 70, that is, the second hinge seat 50 rotates relative to the first housing 70. A plurality of bearing balls 80 are arranged between the second hinge seat 50 and the wall of the receiving cavity 720 to reduce the friction between the second hinge seat 50 and the wall of the receiving cavity 720, thereby improving the rotation smoothness of the second hinge seat 50 relative to the first shell 70.

[0106] Optionally, combined Figure 3 and Figure 4 As shown, the first housing 70 is provided with a plurality of sliding grooves 730, and along the circumference of the receiving cavity 720, the plurality of sliding grooves 730 are spaced and distributed on the cavity wall of the receiving cavity 720. The plurality of sliding grooves 730 are arranged one by one corresponding to the plurality of bearing balls 80.

[0107] In this embodiment, a plurality of sliding grooves 730 are arranged in one-to-one correspondence with a plurality of bearing balls 80. By opening a plurality of sliding grooves 730 in the wall of the receiving cavity 720 along the circumference of the receiving cavity 720, the bearing balls 80 can be rotatably arranged in the sliding grooves 730, so that the bearing balls 80 are slidably connected with the wall of the receiving cavity 720, and at the same time, the bearing balls 80 are limited to be able to rotate only in the original position, and cannot be rotated along the circumference of the receiving cavity 720 with the second hinge seat 50. By limiting the bearing balls 80 to be able to rotate only in the original position, and cannot be rotated along the circumference of the receiving cavity 720 with the second hinge seat 50, the rotation stability of the bearing balls 80 is improved, and then the rotation stability of the second hinge seat 50 relative to the first housing 70 is improved, and the reliability of the hinge mechanism 1 is improved.

[0108] Optionally, combined Figure 3 , Figure 4 and Fig.10 As shown, part of the bearing ball 80 is located in the sliding groove 730236, and the shape of the sliding groove 730 is adapted to the shape of the part of the bearing ball 80.

[0109] In this embodiment, the bearing ball 80 is limited by limiting that part of the bearing ball 80 is located in the sliding groove 730, and the shape of the sliding groove 730 is adapted to the shape of part of the bearing ball 80, so as to achieve the limitation of the bearing ball 80. Specifically, during the rotation of the second hinge seat 50, the bearing ball 80 is driven to rotate. Since part of the bearing ball 80 is located in the sliding groove 730, the bearing ball 80 cannot rotate along the circumference of the receiving cavity 720 with the second hinge seat 50, so that the bearing ball 80 rotates in the original position. By limiting the bearing ball 80 by the sliding groove 730, the rotation stability of the bearing ball 80 is improved, and the rotation stability of the receiving structure 60 relative to the first shell 70 is improved.

[0110] Optionally, combined Figures 3 to 10 As shown, the second hinge seat 50 further includes a clamping portion 518. The clamping portion 518 is located on the third end surface 516 of the second hinge seat 50.

[0111] In this embodiment, the clamping portion 518 is located at the third end surface 516 of the second hinge seat 50. When the hinge mechanism 1 is assembled on a box or a door, the clamping portion 518 is used to be connected to the box or the door.

[0112] Optionally, combined Figures 3 to 10 As shown, the clamping portion 518 includes a plurality of clamping grooves 520 , and the plurality of clamping grooves 520 are spaced apart on the clamping portion 518 .

[0113] In this embodiment, a plurality of clamping grooves 520 are provided on the clamping portion 518 to improve the connection stability when the clamping portion 518 is connected to the box body or the door body.

[0114] It should be noted that the specific shape and number of the multiple card slots 520 need to be specifically set according to the actual equipment, and are not specifically limited in this application.

[0115] Optionally, combined Figure 1 As shown, the first hinge assembly 10 further includes a hinge plate 120. The hinge plate 120 is provided with a third hinge hole. The hinge shaft 110 passes through the third hinge hole and is connected to the first hinge seat 30 and the second hinge seat 50.

[0116] In this embodiment, the hinge shaft 110 passes through the third hinge hole, the first hinge hole 312 and the second hinge hole 512 in sequence, so that the hinge plate 120, the first hinge seat 30 and the second hinge seat 50 form a sleeve structure through the hinge shaft 110, thereby realizing the connection setting between the first hinge assembly 10 and the second hinge assembly 20, and further improving the connection stability between the first hinge assembly 10 and the second hinge assembly 20. When the hinge mechanism 1 is assembled on a box or a door, the hinge plate 120 is used to be connected with the box or the door.

[0117] In some embodiments, in combination Fig.13 As shown, a refrigerator 2 is provided, comprising a box body 3, a door body 4 and a hinge mechanism 1 as described in the above embodiment. The box body 3 defines a storage compartment. The door body 4 is used to open or close the storage compartment. In the hinge mechanism 1 as described in the above embodiment, the first hinge assembly 10 is installed on one of the box body 3 and the door body 4, and the second hinge seat 50 is connected to the other of the box body 3 and the door body 4 at one end away from the receiving structure 60, so that the door body 4 can rotate relative to the box body 3.

[0118] In this embodiment, the first hinge assembly 10 is installed in one of the box body 3 and the door body 4, and the second hinge seat 50 is connected to the other of the box body 3 and the door body 4 at one end away from the receiving structure 60. Since the second hinge seat 50 can rotate relative to the hinge shaft 110, a pivotable connection between the door body 4 and the box body 3 is achieved. In addition, since the transmitting structure 40 and the receiving structure 60 can achieve different conduction states, compared with the related art, the structural design of inserting the wire into the hinge shaft 110 and making the two ends of the wire respectively located in the door body 4 and the box body 3 is avoided. Therefore, by using the hinge mechanism 1 to be set between the door body 4 and the box body 3, in the process of rotating the door body 4 and the box body 3, the wire harness will not be deformed and the service life of the harness will not be reduced, thereby improving the service life of the hinge mechanism 1 and reducing the probability of accidental power failure during power supply due to the breakage of the harness.
