Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to an automobile battery power-off control structure and an automobile. Background Art

[0002] Existing technology typically disconnects the vehicle's low-voltage power supply by directly using tools to disconnect the battery's negative terminal (deenergizing the negative battery post). This process is cumbersome and requires specialized tools. It also generates sparks, posing a safety hazard. Furthermore, frequent disconnection of the battery post reduces connection reliability, damages the post, and reduces the battery's lifespan. Other battery disconnection solutions integrate the battery disconnection strategy into the vehicle controller. This strategy is dependent on the vehicle configuration (and controller logic) and requires support from the vehicle controller. It's not suitable for disconnecting batteries after temporary installation, such as when modifying a test vehicle. Utility Model Content

[0032] Figures 1 to 6 The schematic diagram of the structure of the vehicle battery power-off control structure provided by the embodiment of the utility model is shown. Figures 1 to 6 As shown, the first embodiment of the present invention provides a vehicle battery power-off control structure, including a battery 1, a relay 2 and an operating switch 3. The battery 1 and the relay 2 are arranged in the engine area of ​​the vehicle, and the operating switch 3 is arranged in the cockpit area of ​​the vehicle. One end of the operating switch 3 is connected to the positive pole of the battery 1, and the other end of the operating switch 3 is connected to the positive pole of the relay 2. The negative pole of the battery 1 is connected to the negative pole 21 of the relay 2.

[0033] The automobile battery power-off control structure provided by the embodiment of the present invention is achieved by arranging the battery 1 and the relay 2 in the engine compartment area of ​​the automobile, and arranging the operating switch 3 in the cockpit area of ​​the automobile. The operating switch 3 is respectively connected to the positive pole of the battery 1 and the positive pole of the relay 2, and is connected to the negative pole 21 of the relay 2 through the negative pole of the battery 1. The operation of the relay 2 is controlled by the operating switch 3, thereby controlling the power on and off of the battery 1. The power on and off operations of the battery 1 can be completed quickly and conveniently through the operating switch 3 without using tools, with high safety and reliability, and effectively avoiding safety hazards. At the same time, the operating switch 3 is arranged in the cockpit area of ​​the automobile, which is easy to operate and there is no need to open the engine compartment cover. In addition, the above-mentioned battery power-off control structure has a simple structure and can be installed as a special automotive wiring harness. It does not need to be associated with the vehicle control and does not require additional modifications to the vehicle controller and related software. It has little impact on the vehicle's own status, is easy to modify, and has a wide range of applications. It is particularly suitable for power-off protection of automobiles in the early stages of research and development where power management is immature or for modification and testing conditions that require disconnection of low-voltage power during the research and development process, making it convenient to test and verify automobile problems in the research and development stage.

[0034] In some embodiments, as Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the battery 1 includes a battery negative electrode clamp 11, and the negative electrode of the battery 1 is connected to the negative electrode post 21 of the relay 2 through the battery negative electrode clamp 11; the negative electrode post 21 of the relay 2 is also connected to the working circuit of the relay 2 through the first terminal 4.

[0035] The battery negative electrode clip 11 is installed at the negative electrode of the battery 1 and is connected to the negative electrode post 21 of the relay 2 through a wire. At the same time, the negative electrode post 21 of the relay 2 is also connected to the working circuit of the relay 2 through the first terminal 4, which facilitates the control of the operation of the relay 2, and then controls the power on and off of the battery 1, and ensures the safety and reliability of the circuit.

[0036] Optionally, the relay 2 is a 300A-12VDC relay with high sensitivity. Within the operating voltage range of the 12V relay, the relay 2 can work normally and realize the on and off of its switching circuit (working circuit), which is safe and reliable.

[0037] In some embodiments, as Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, the positive electrode of the battery 1 is provided with a second terminal 5 connected to the operating switch 3. The second terminal 5 is connected to the positive terminal box of the battery 1 and is connected to the operating switch 3 through a wire to ensure the safety and reliability of the circuit.
