The first hinge 10 and the second hinge 20 provided by the present embodiment are connected together through the connection structure 30, and the first hinge 10 and the second hinge 20 can rotate relatively, and in the process of rotating, the conductive member 40 in the first hinge 10 and the conductive member 40 in the second hinge 20 can also be kept in contact connection, so as to ensure a continuous and stable power-on effect.

In addition, it should be noted that the conductive member 40 in this embodiment replaces the cable or wire harness connection between the power supply device and the electrical component in the related art, and the conductive member 40 can avoid the phenomenon of the service life reduction of the wire harness caused by the wire harness being stretched and contracted when the vehicle door is in operation, thereby further improving the reliability and stability of the over-current connection device 100. Meanwhile, the overcurrent connecting device 100 provided in this embodiment is an independent component, and is independently installed and separated from the hinge (e.g., hinge) between the fixed member 210 and the rotating member 220, so that the convenience of maintaining the circuit of the electrical component is improved without reducing the strength of the hinge.

In some embodiments, as shown in fig. 2, the connection structure 30 includes a first hinge hole 11, a second hinge hole 21, and a shaft pin 31. The first hinge element 10 is provided with a first hinge hole 11, the second hinge element 20 is provided with a second hinge hole 21, and the shaft pin 31 penetrates through the first hinge hole 11 and the second hinge hole 21, so that the first hinge element 10 and the second hinge element 20 rotate coaxially around the shaft pin 31.

By arranging the connection terminal 41, the conductive member 40 can be connected to the electrical component conveniently, the conductive member 40 can be connected to the electrical component more firmly, and the possibility of connection failure between the conductive member 40 and the electrical component in the rotating process of the first hinge 10 and the second hinge 20 is reduced, so that the use stability and reliability of the electrical connection device 100 are further improved.

Further, a connection terminal 41 connected to the conductive member 40 in the first hinge 10 extends out of the first interface 12. Likewise, a wire terminal 41 connected to the conductive member 40 in the second hinge 20 extends out of the second interface 22.

The opening structure 200 provided in this embodiment includes the electrical connection device 100 in any of the above embodiments, so that all the advantages of any of the above embodiments are provided, and no further description is provided herein.

In addition, the opening structure 200 provided in this embodiment further includes a hinge, the fixed component 210 and the rotating component 220 are rotatably connected by the hinge, the electrical connection device 100 is an independent component, and is independently installed and separated from the hinge (such as a hinge) between the fixed component 210 and the rotating component 220, so as to improve the convenience of line maintenance of electrical components without reducing the strength of the hinge.

Some embodiments of the application provide a cab 300 including a frame 310, a door 320, and an electrical connection apparatus 100 of any of the embodiments described above.

Specifically, as shown in fig. 9, a power supply device 340 is provided in the frame 310; the vehicle door 320 is rotatably connected with the frame 310 through a hinge 330, and an electrical component 350 is arranged on the vehicle door 320; and the over-current connection device 100 in any of the above embodiments, both ends of the over-current connection device 100 are respectively connected with the power supply device 340 in the frame 310 and the electrical component 350 on the vehicle door 320, and the over-current connection device 100 is adapted to rotate synchronously with the hinge 330.

For example, in the case where the hinge 330 is a hinge, when the vehicle door 320 is opened and closed, the two hinge leaves of the hinge rotate relatively, and the first hinge 10 and the second hinge 20 of the electrical connection device 100 rotate relatively, and the direction and the amplitude of the relative rotation of the first hinge 10 and the second hinge 20 are the same as those of the relative rotation of the two hinge leaves of the hinge.

The following description will specifically describe the electrical connection device 100, the opening structure 200, and the cab of the vehicle.

At present, the connection mode of the electrical components in the vehicle door and the frame power supply device mostly adopts the following structural form: the bottom of the vehicle door is provided with a hole corresponding to the position of the frame, the wire harness passes through the hole and the hole, the wire harness is stretched when the vehicle door is opened, and the wire harness shrinks to the inner side of the hole when the vehicle door is closed. The existing hinge device capable of passing the wire comprises a hinge body arranged between an inner window frame and an outer window frame, wherein a wire passing structure for leading a wire to enter the inner window frame from the outer window frame is arranged in the hinge body. However, the wire passing structure has the following disadvantages: the pencil directly exposes between door and frame, and the pencil is tensile when opening, and the pencil shrink can appear in the time of closing even the phenomenon that the pencil shrink is not in time extruded between door and door frame. The hinge is of an inner frame structure and an outer frame structure, the middle of the hinge is hollow, and the strength of the hinge is insufficient. The hinge is used as a connecting mechanism, and the strength requirement is high. The pencil passes from the centre, not only has the pencil tensile and shrink problem when the hinge is rotatory, still has the pencil rotation, influences pencil life. The inner frame and the outer frame of the hinge are connected through bolts, the sealing performance is poor, water is easy to accumulate, and the risk of wire harness short circuit exists. The hinge is dismantled to the pencil from the hinge when overhauing, and the door is dismantled simultaneously, influences door installation accuracy.

To this end, the present embodiment provides an electrical interconnection device 100, which includes two hinge members (a first hinge member 10 and a second hinge member 20), the two hinge members are connected by a pin, a core of the hinge member structure is a conductive member 40 (made of a conductive material), an outer ring of the conductive material is an insulating layer 42, and an outer side of the insulating layer 42 is a hinge member of the electrical interconnection device 100.

The hinged parts are connected through a pin shaft, and rotate around the pin shaft when the vehicle door is opened and closed.

Specifically, the hinged member is a rotary device, and the opening and closing of the device are completed along with the work of the vehicle door. A clamp spring 60 is arranged between the two hinged pieces, and the device moves along with the hinge in the working process. The outer ring of the core part between the hinge parts is provided with a water retaining sealing rubber sleeve. The hinge core is a conductive material, not a wire harness. The electrical connection device 100 is mounted separately and not fixed to the door hinge. The electrical connection apparatus 100 may be applied to various swing door type structures, not just vehicle doors.

In the use process, when the vehicle door is opened, the hinged parts rotate around the pin shaft to open for a certain angle, when the vehicle door is closed, the two hinged parts are overlapped up and down, and the whole width of the electric connecting device 100 is contracted and hidden between the vehicle door and the door frame.

The electric connecting device 100 is separated from the hinge of the vehicle door and used as a single device, so that the maintenance convenience of the circuit of the electric appliance element is improved on the basis of not reducing the strength of the hinge, and the reliability and the maintenance convenience of the vehicle door can be ensured; the conductive portion of the electrical connection device 100 is designed as a unitary conductive material that is configured to open and close the device by pivoting about a hinge pin between two hinged members. In the working process, the hinged pieces rotate mutually and keep contact, the clamp springs 60 are arranged between the hinged pieces, the clamp springs 60 are stretched when the vehicle door is opened, and the device is rotated to be opened; when the door is closed, the snap spring 60 contracts, and the device rotates to close. The wireless beam stretches, contracts and rotates in the whole working process, so that the service life is ensured; the periphery of the upper part and the lower part of the device is provided with a groove for installing a sealing rubber sleeve when being connected, so that the power-on safety is ensured

In summary, the electrical connection apparatus 100 and the opening structure 200 provided in the present embodiment have at least the following advantages: the electric connecting device 100 is independently installed on the vehicle door and the frame, and only the device needs to be disassembled during maintenance, so that the vehicle door is not involved, and the maintenance convenience is improved. Meanwhile, the influence on the strength of the hinge due to integration on the hinge is avoided. The harness is directly electrified instead of the conductive material (the conductive member 40), and the electric connecting device 100 rotates to open and close when the vehicle door works, so that the phenomenon that the service life of the harness is shortened due to the fact that the harness is stretched and contracted when the vehicle door works is avoided. The device connecting part is designed with a water-stop sealing rubber sleeve, so that the safety and reliability of the line in work are ensured.
