Referring to fig. 1-2, fig. 1-2 illustrate a high voltage power distribution apparatus provided in an embodiment of the present application.

The high-voltage distribution device can also be called as a high-voltage distribution box or a high-voltage distribution box, and has the main function of distributing electric energy, namely distributing high-voltage direct current of a power battery to high-voltage electric equipment such as a motor controller, a driving motor, a motor air conditioner and the like, so as to ensure the normal operation of all parts of a vehicle.

In one embodiment, the present application provides a high voltage power distribution device comprising a housing, a battery connector 400, and a power conversion connector 100, wherein the housing has an electrical installation cavity. The battery connector 400 is for electrical connection with an external battery and is mounted to the housing. The electrical replacement connector 100 is mounted to the housing and electrically connected with the battery connector 400 in the electrical installation cavity.

Through integrating the electric connector 100 on the shell of the high-voltage distribution device, the electric connector 100 can be directly electrically connected with the battery connector 400 through electric parts (elements such as a relay, a Hall sensor, a BMS and the like which are mentioned later) arranged in the shell and finally electrically connected with an external battery through the battery connector 400, so that the electric connector 100 becomes a part of the high-voltage distribution device, a replacement electric box is not required to be independently arranged outside the high-voltage distribution device, the space utilization rate is improved, and the use of a plug connector and a high-voltage cable between the electric box and the high-voltage distribution device when the electric box is connected is avoided, so that the cost is reduced.

Specifically, the housing includes a lower case 300 and an upper cover 200, and the upper cover 200 is covered on the lower case 300 and encloses an electrical installation cavity together with the lower case 300. The battery connector 400 is mounted to the lower case 300, and the battery replacement connector 100 is mounted to the upper cover 200. It will be appreciated that under normal placement conditions, the high voltage power distribution device is located above, i.e., the upper cover 200, and below, i.e., the lower housing 300, the upper cover 200. By mounting the electrical replacement connector 100 on the upper cover 200, the plugging operation can be performed conveniently. The battery connector 400 is provided to the lower case 300, and it is possible to connect an external power battery, for example, to electrically connect electrodes of the battery with the battery connector 400.

The electrical connector 100 is disposed on the upper cover 200, so that force can be transmitted downwards during plugging and unplugging, and plugging is facilitated. When power is supplied, the power exchange connector 100 of the high-voltage power distribution device can be communicated with the power exchange connector 100 at the vehicle body end, so that the electric energy exchange between the battery and the vehicle body is realized. The number of the electrical replacement connectors 100 may be determined according to the requirement, and only one electrical replacement connector 100 may be provided, or two electrical replacement connectors 100 may be provided, which is not limited in the present application. As shown in fig. 2, 3 power conversion connectors 100 are disposed on the upper cover 200, and all of the 3 power conversion connectors 100 are electrically connected with the battery connector 400.

Further, the upper cover plate 200 is a steel cover plate having a thickness of 7mm or more. The arrangement can make the upper cover plate 200 have stronger external force tolerance, so that even if the electrical connector 100 arranged on the upper cover plate 200 is more in plugging times and large in plugging force, the upper cover plate 200 can not deform and lose efficacy in the life cycle, and the problems of poor airtight, abnormal opposite plugging and the like caused by deformation and invalidation are avoided.

It should be noted that, the external force tolerance of the component panel of the lower case 300 may be smaller than the external force tolerance of the upper cover 200, for example, the component panel of the lower case 300 may be set to be an aluminum plate with a thickness of less than 7mm, so that the manufacturing cost of the lower case 300 may be reduced while ensuring that the upper cover 200 meets the insertion and extraction requirements of the electrical connector 100.

The external force tolerance is associated with whether the plate body is easy to deform, and is high, so that the plate body is not easy to deform under the action of external force, and is low, so that the plate body is easy to deform under the action of external force. The external force tolerance of the upper cover plate 200 is higher than that of the constituent panels of the lower case 300, i.e., the upper cover plate 200 is less likely to be deformed than the constituent panels of the lower case 300. The upper cover 200 may be made of a material having higher strength, and the upper cover 200 may have a greater thickness than the constituent panels of the lower case 300.

The electrical replacement connector 100 is electrically connected with the battery connector 400 in the appliance mounting cavity. In one embodiment, the high voltage power distribution device comprises a relay 800 and a hall sensor 900, wherein the relay 800 and the hall sensor 900 are both positioned in the electric installation cavity and are arranged on an electric connection path between the electric replacement connector 100 and the battery connector 400. It can be appreciated that by providing the relay 800 and the hall sensor 900 in the electrical connection paths of the battery connector 400 and the battery connector 100, the relay 800 can protect the circuit and cut off the circuit when a fault such as overcurrent occurs. The hall sensor 900 may be a current sensor or a voltage sensor. The hall sensor 900 may measure a current or voltage in a path so that a fault may be detected based on the current. In particular, the electrical replacement connector 100 may be connected to one end of the relay 800 through the copper bar 305, and the other end of the relay 800 is connected to the battery connector 400 through the copper bar 305. The hall sensor 900 is sleeved on the copper bar 305 for sensing detection.

The battery connector 400 may include a battery positive interface and a battery negative interface. In an embodiment, the battery positive electrode interface may include a plurality of positive electrode sub-interfaces, such as a first positive electrode sub-interface, a second positive electrode sub-interface, and a third positive electrode sub-interface.

In one embodiment, at least one side cover plate 302 is detachably connected to the frame 301. Here, detachable connection means a connection mode in which detachment is convenient and damage to the components is not generated, for example, connection by fixing members such as screws, snap connection, and the like. And the modes of welding, bonding, integral forming and the like do not belong to detachable connection. The side cover plate 302 is detachably connected with the frame 301, namely, a maintenance window is formed in the side face of the high-voltage distribution device, so that electric components close to the side cover plate 302 in the electric installation cavity can be maintained and overhauled conveniently.

In one embodiment, the upper cover plate 200 may also be detachably connected to the frame 301, thereby facilitating maintenance and repair of electrical components within the electrical installation cavity proximate to the upper cover plate 200.

In one embodiment, the lower cover plate 303 may be detachably connected to the frame 301 to facilitate maintenance and repair of electrical components disposed within the electrical installation cavity proximate the lower cover plate 303.

There are various ways of achieving the sealing connection, and in one example, a sealing ring 304 may be provided between the frame 301 and the panel, and the sealing ring 304 may be pressed by a fastener such as a screw to achieve the waterproof sealing. In one example, a sealant may be filled at the connection of the frame 301 and the panel, and waterproof sealing may be achieved by the sealant.

In one embodiment, the remote communication terminal 600 and the antenna box 700 may be configured for a high voltage power distribution device. Here, the remote communication terminal 600 may also be called as a vehicle-mounted T-BOX (Telematic BOX), and has a main function of uploading various information of a vehicle to the TSP background as a portal for data acquisition, and receiving a background instruction to feed back an execution result. The remote communication terminal 600 may be disposed in the electric appliance mounting cavity, and the antenna case 700 is mounted to the outer surface of the lower case 300. The remote communication terminal 600 may be in communication connection with the antenna box 700, and receive and transmit signals using the antenna in the antenna box 700, so as to implement functions of software remote upgrade, remote reception of vehicle data, etc., and reduce after-sales maintenance costs. Further, the antenna box 700 is mounted on an outer surface of the side cover plate 302 facing away from the appliance mounting cavity.
