It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0037] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0038] In the related art, a power interface is usually provided for aftermarket electrical appliances through a cigarette lighter or a power socket in a vehicle, or a repair shop or a user can power aftermarket electrical appliances by adding a fuse to the vehicle, unplugging wires, etc. However, the above scheme can only adapt to aftermarket electrical appliances that only have power requirements, and cannot adapt to other aftermarket electrical appliances with additional requirements. In order to solve the above problems, an embodiment of the present invention proposes an electrical connection structure and a vehicle. The above-mentioned electrical connection structure and vehicle are described in detail below.

[0039] First, refer to Figures 1 to 5 The electrical connection structure provided by the embodiment of the present invention includes a vehicle-end interface 1, a connector 7 and a vehicle-end wiring harness 2. The vehicle-end interface 1 includes a plurality of first terminals 101 having a first power terminal, a first communication terminal and a first signal terminal. The connector 7 includes a plurality of second terminals that are plugged into and matched with the plurality of first terminals 101 one by one. The electrical appliance is electrically connected to the vehicle-end interface 1 through at least one second terminal of the connector 7. The vehicle-end wiring harness 2 includes a power line, a communication line 205 and a signal line that are electrically connected to the first power terminal, the first communication terminal and the first signal terminal respectively. The power line is used to supply power to the electrical appliance, the communication line 205 is used for communication between the electrical appliance and the vehicle, and the signal line is used to transmit control signals to the electrical appliance.

[0040] Among them, the electrical appliances may be aftermarket electrical appliances or aftermarket controllers 9. Aftermarket electrical appliances refer to devices installed by users or third parties after the vehicle leaves the factory, which are used to enhance the functions of the vehicle or improve the user experience. Aftermarket electrical appliances may be reversing image systems, reversing radars, driving recorders, players, wireless chargers, car refrigerators, aftermarket ambient lights, etc. Aftermarket controllers 9 refer to electronic control modules installed by users or third parties after the vehicle leaves the factory, which are used to control, manage or expand aftermarket electrical appliances and interact with the original systems of the vehicle.

[0041] The connector 7 includes a plug-in shell 701, and a plurality of second terminals are detachably connected to the plug-in shell 701. The vehicle-end interface 1 includes an interface shell 102, and the plug-in shell 701 is plugged into and matched with the interface shell 102. The electrical appliance is a post-installed controller 9, and the post-installed controller 9 includes a controller shell, and the plug-in shell 701 is connected to the controller shell; or, the electrical appliance is a post-installed electrical appliance, and the post-installed electrical appliance includes an electrical appliance wiring harness 8, and the electrical appliance wiring harness 8 includes at least one conductive wire electrically connected to at least one second terminal.

[0042] The interface housing 102 may have a slot, and the plug housing 701 is in the form of a plug, and the plug housing 701 in the form of a plug is inserted into the slot of the interface housing 102. The connection between the second terminal and the plug housing 701 may be a snap connection, a screw connection, etc. The plug housing 701 and the controller housing may be an integral structure, for example, integrally injection molded, or a split structure. The after-installed controller 9 is electrically connected to the vehicle-end interface 1 through all the second terminals of the connector 7.

[0043] In the case where there is a large plane at the location where the vehicle-end interface 1 is arranged, the electrical appliance can be a post-installed controller 9. In the case where the location where the vehicle-end interface 1 is arranged has limited space and / or the post-installed electrical appliance has its own electrical appliance wiring harness 8, the electrical appliance can be a post-installed electrical appliance. For different post-installed electrical appliances, the number of conductive wires of the electrical appliance wiring harness 8 is different, and the number of second terminals electrically connected to the electrical appliance wiring harness 8 is different. For the second terminal that is not electrically connected to the electrical appliance wiring harness 8, that is, the unused second terminal, it can be removed from the plug housing 701 to reduce unnecessary electrical contact points.

[0044] Before designing the multiple first terminals 101 of the vehicle-side interface 1 and the multiple wires of the vehicle-side wiring harness 2, it is possible to conduct a survey on the electrical appliances that users often install, and to collect the circuit information required by the electrical appliances that users often install, such as current information, voltage information, whether communication with the vehicle is required, whether control signals from the vehicle end are required, etc., and design the multiple first terminals 101 of the vehicle-side interface 1 and the multiple wires of the vehicle-side wiring harness 2 accordingly according to the survey results. According to the survey results, select appropriate wire diameters, wire directions, etc., and select appropriate first terminals 101 and second terminals to ensure that the user will not exceed the maximum carrying current of the wires and terminals when installing electrical appliances normally, thereby ensuring the safety of the vehicle. Select the position of the vehicle-side interface 1 according to the layout of the electrical appliances. In the case where the electrical appliance is a post-installed controller 9 and the plug-in housing 701 is connected to the controller housing, when selecting the position of the vehicle-side interface 1, it is also necessary to ensure that there is enough space near the vehicle-side interface 1 to arrange the post-installed controller 9.

The first terminal 101 can be a male terminal, in which case the second terminal is a female terminal. The plurality of second terminals include a second power terminal that is plugged in with the first power terminal, a second communication terminal that is plugged in with the first communication terminal, and a second signal terminal that is plugged in with the first signal terminal. The number of first terminals 101 in the vehicle-side interface 1 is greater than or equal to four, and the number of first terminals 101 can be four, five, six, seven, eight, etc.

[0046] The multiple wires of the vehicle-end wiring harness 2 correspond one-to-one to the multiple first terminals 101, that is, the number of wires in the vehicle-end wiring harness 2 is equal to the number of first terminals 101 in the vehicle-end interface 1. The multiple wires of the vehicle-end wiring harness 2 can be tied together to integrate the multiple wires into a wiring harness. The vehicle-end wiring harness 2 also includes a sheath arranged on the multiple wires. The communication line 205 specifically realizes the communication between the electrical appliance and the vehicle control system through the CAN (Controller Area Network) bus 12, and the signal line is specifically used to transmit the control signal output by the body controller 10 to the electrical appliance. The control signal can be a reversing signal, an enable signal, etc.

[0047] When installing the aftermarket controller 9, the user only needs to confirm that the interface definition of the aftermarket controller 9 matches the interface definition of the vehicle-end interface 1, and then plug the connector 7 into the vehicle-end interface 1. When installing aftermarket electrical appliances, the user only needs to confirm that the interface definition of the aftermarket electrical appliances matches the interface definition of the vehicle-end interface 1, and then connect the electrical appliance harness 8 of the aftermarket electrical appliances to the connector 7, and then plug the connector 7 into the vehicle-end interface 1.

[0048] For aftermarket electrical appliances that only need electricity, the conductive wires of the electrical appliance harness 8 are electrically connected to the second power terminal, and the aftermarket electrical appliances are electrically connected to the vehicle-end interface 1 through the second power terminal. For aftermarket electrical appliances that need electricity and need to communicate with the vehicle, the conductive wires of the electrical appliance harness 8 are electrically connected to the second power terminal and the second communication terminal, and the aftermarket electrical appliances are electrically connected to the vehicle-end interface 1 through the second power terminal and the second communication terminal. For aftermarket electrical appliances that need electricity, need to communicate with the vehicle, and need to receive control signals from the vehicle, the conductive wires of the electrical appliance harness 8 are electrically connected to the second power terminal, the second communication terminal, and the second signal terminal, and the aftermarket electrical appliances are electrically connected to the vehicle-end interface 1 through the second power terminal, the second communication terminal, and the second signal terminal.

[0049] In the embodiment of the present invention, the vehicle-end interface 1 includes a first power terminal, a first communication terminal, and a first signal terminal, and the vehicle-end wiring harness 2 includes a power line, a communication line 205, and a signal line. The electrical appliance is electrically connected to the vehicle-end interface 1 through the connector 7. The vehicle-end wiring harness 2, the vehicle-end interface 1, and the connector 7 can not only supply power to the electrical appliance, but also realize communication between the electrical appliance and the vehicle, and can also transmit control signals to the electrical appliance, so as to adapt to electrical appliances that need electricity and / or need to communicate with the vehicle and / or need to receive control signals from the vehicle, meet the different installation requirements of users, and improve the user experience. In addition, the second terminal in the connector 7 is plugged in and matched with the first terminal 101 of the vehicle-end interface 1, which can greatly improve the convenience and practicality of users installing electrical appliances, improve the safety of the vehicle, and reduce the risk of vehicle burning caused by irregular circuit modification.

[0051] Wherein, the second signal terminal includes a second reversing signal terminal plugged with the first reversing signal terminal, and / or, the second signal terminal includes a second enable signal terminal plugged with the first enable signal terminal. The reversing signal line 203 and the enable signal line 204 are specifically electrically connected to the I / O (Input / Output) interface of the body controller 10. The reversing signal is output based on the driving state of the whole vehicle. When the vehicle is in the reverse gear, the body controller 10 outputs the reversing signal to the rear-mounted reversing radar or reversing image system to provide a reversing signal to the reversing radar or reversing image system. The reversing signal can be a high-level signal.
