Problems solved by technology

[0004] The electrical connector mounting plate in the existing power transfer box is fixed, such as Figure 5 As shown, the electrical connector mounting plate is fixedly connected to the box body and is perpendicular to the bottom surface of the box body 1. The electric cable connector on the vehicle is installed on the electrical connector mounting plate in the power transfer box through screws. When external power supply is required , plug the external power supply cable into the electrical connector on the transfer box. At this time, the electrical connector of the external power supply cable is vertically inserted into the vertical electrical connector in the power transfer box. The rest of the external cable is due to gravity. Hanging on the ground, because the external power supply cable itself is generally heavy, the root of the external power supply cable electrical connector bears the largest bending moment. Since the electrical connector and the cable are in the form of a welded structure, excessive force for a long time will cause the external cable to Danger of breaking solder wires inside electrical connectors
[0005] At the same time, due to the high chassis of some vehicles, the position of the transfer box is raised accordingly, exceeding the normal and comfortable height of the human body. Since the cable electrical connector needs to be accurately docked, and the electrical connector mounting plate is fixed vertically , cannot move and change the angle, so the operator does not have a good observation angle, which makes it very inconvenient to plug and unplug the cable. Intelligent use of auxiliary materials such as skids and ladders, but these items are not always available

Embodiment 1

[0047] The invention provides a power adapter box with a turning mechanism, the electrical connector mounting plate of which is linked with the front door, so that when the front door is opened, the adapter plate is turned forward with the front door at a certain angle, which is convenient for the operator to operate at a lower level. The cable can be plugged and unplugged in the position, and at the same time, it can avoid the root of the electrical connector from being subjected to a large bending moment.

[0048] The design scheme of the present invention is a power adapter box with a turning mechanism, and the overall structure schematic diagram is as follows Figure 1-2 shown.

[0049] The main structure of the power transfer box includes a box body 1, a front door 2, a connecting plate 3, an electrical connector mounting plate 4 and a gas spring 6, such as image 3 shown.

[0050]The box body 1 is a cuboid sheet metal structure with front and rear square holes closed o...

Embodiment 2

[0067] The present invention provides a power adapter box with a turning mechanism, the overall structure schematic diagram is as follows Figure 1-2 shown.

[0068] The main structure of the power transfer box includes a box body 1, a front door 2, a connecting plate 3, an electrical connector mounting plate 4 and a gas spring 6, such as image 3 shown.

[0069] The box body 1 is a cuboid sheet metal structure with front and rear square holes closed on all sides, the rear part is the cable inlet and outlet on the car, and the front part is the installation position of the front door; there are 2 pairs of hinge mounting holes at the bottom, which are used for the box body 1 and the electrical connector installation The hinge between the plates 4 is installed, and the bottom is welded with 2 lugs, which are used for the hinged fixing of the gas spring pressure cylinder.

[0070] The front door 2 is a rectangular sheet metal structure with flanges around it, and two lugs are w...

Embodiment 3

[0085] A power transfer method, using the power transfer box with a turning mechanism in Embodiment 1, comprising the following steps:

[0086] S1, rotate and open the handle of the door lock 7 on the front door 2;

[0087] Rotate to open the door lock on the front door 2, and the front door 2 is opened under the action of the gas spring. The gas spring forms a triangle structure with the connection plate 3 and the electrical connector installation plate 4. The stability principle of the triangle is used to ensure that the power supply rotates when the cable is plugged and unplugged. The stability of the junction box structure, at this time, the operator can have a better operating angle to plug and unplug the external cable.

[0088] S2. Switch the connection between the gas spring pressure cylinder and the round holes in different positions, adjust the opening angle of the front door and the angle of the electrical connector mounting plate 4;

[0089] By switching the conne...

Abstract

The invention relates to a power transfer box with a flipping mechanism and a power transfer method, which belongs to the field of vehicle power supply technology and solves the technical problems in the prior art of poor viewing angles for operators and easy breakage of the roots of electrical connectors. The power adapter box with a flip mechanism of the present invention includes a box body, a front door, a connecting plate, an electrical connector mounting plate and a gas spring; two long lugs are fixedly connected to the bottom of the box body; the connecting plate is connected to the front door and the electrical connector respectively. The mounting plate is rotatably connected; the electrical connector mounting plate is rotatably connected to the bottom of the box and the connecting plate; the gas spring is rotatably connected to the front door and the long lug; the long lug is a long bent strip with internal toothed grooves. parts; the gas spring is a free-type compression gas spring with a protective sleeve. The power adapter box with a flip mechanism of the present invention can adjust the angles of the front door and the electrical connector mounting plate.

Description

technical field [0001] The invention relates to the technical field of vehicle power supply, in particular to a power adapter box with a turning mechanism. Background technique [0002] At present, a large number of equipment on the vehicle need power supply. Some of the power supply comes from the battery on the vehicle, and some come from the diesel generator set on the vehicle. When the power supply on the vehicle cannot work normally or there are other needs, it needs to be supplied from the outside of the vehicle. Connect the power supply to supply power to the on-board equipment, such as mains power, etc. At this time, a power adapter box is required as an adapter device to realize the connection between the external power supply and the power supply cable interface on the vehicle. Therefore, the power adapter box is generally used as a part of the on-board power supply device. In some necessary occasions, it can realize the input transfer of external power supply such...
