Description

Technical Field

[0001] This utility model relates to the field of electrical energy in new energy commercial vehicles, and in particular to a portable power main switch circuit for new energy commercial vehicles. Background Technology

[0002] When a commercial vehicle is turned off, although the vehicle as a whole no longer consumes a large amount of electricity, the electrical appliances in the vehicle have static current to maintain standby status, which will continuously consume the battery's power. If the battery power is not disconnected, the battery will be completely depleted after a long period of parking, and the vehicle will not be able to start normally.

[0003] Existing power cut-off switches are typically located at the bottom of vehicles, especially on trucks where the switch is often far from the cab, requiring the driver to get out and turn it off. This inconvenience for drivers during extended periods of parking, coupled with the current system, leads to drivers frequently forgetting to turn off the power cut-off switch when parking and locking the doors. This results in the battery not being disconnected in time, reducing its charge retention time.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0021] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises", "made for", etc., shall be understood to include the stated elements or components, without excluding other elements or other components.

[0022] The purpose of this utility model is to provide a portable power switch 3 circuit for new energy commercial vehicles, which can save battery standby power consumption and make it convenient for the driver to turn off the vehicle's electrical appliances 11.

[0023] Example 1:

[0024] This embodiment provides a portable power switch 3 circuit for new energy commercial vehicles, including: a main circuit 1, which is used to maintain the operation of the electrical devices of the new energy commercial vehicle; a secondary circuit 2, which is used to selectively disconnect the main circuit 1; and a switch 3, which is connected to both the main circuit 1 and the secondary circuit 2. The portable power switch 3 circuit for new energy commercial vehicles includes a power-on state and a power-off state. In the power-on state, the main circuit 1 is energized and the secondary circuit 2 is energized; in the power-off state, the main circuit 1 is energized and the secondary circuit 2 is energized.

[0025] Specifically, to address the problem of prolonged energy consumption in commercial vehicles while parked and the difficulty in turning off the power-off switch 3, this embodiment incorporates a secondary circuit 2. This circuit, via switch 3, disconnects the main circuit 1, preventing continuous energy consumption after parking. Furthermore, the circuit layout allows the driver to disconnect all electrical appliances from the vehicle. When the portable power switch 3 circuit for new energy commercial vehicles switches from the energized state to the de-energized state, switch 3 closes, disconnecting the main circuit 1 through magnetic repulsion and disconnecting other low-power electrical appliances, ensuring stable battery power after prolonged standby.

[0026] In a preferred embodiment of this invention, the switch 3 is an electromagnetic switch 3 structure, which includes a housing, an electromagnetic coil, a moving iron core, contacts, and a reset spring.

[0027] Specifically, the switch 3 is an electromagnetic switch 3 structure enclosed in a shell. When the contact is closed, the circuit it is in is turned on. The moving iron core and the electromagnetic coil repel each other and push the contact to open, thereby disconnecting the circuit where the contact is located. The reset spring can reset the contact to the closed position.

[0028] In a preferred embodiment of this invention, the housing includes at least four through holes for circuitry to pass through.

[0029] In a preferred embodiment of this invention, the main circuit 1 passes through at least two of the through holes, the moving iron core is connected to the contact, and the contact is connected to the portion of the main circuit 1 inside the housing.

[0030] In a preferred embodiment of this invention, the secondary circuit 2 passes through at least two of the through holes, and the electromagnetic coil is connected to the portion of the secondary circuit 2 inside the housing.

[0031] In a preferred embodiment of this invention, when the electromagnetic coil is energized, it includes a magnetic field that attracts the moving iron core.

[0032] Specifically, such as Figure 1 As shown, when the secondary circuit 2 is energized, the electromagnetic coil generates a magnetic field that attracts the moving iron core. The moving iron core is magnetically attracted to the main circuit 1, thus closing the contacts with the main circuit 1. In other words, the main circuit 1 can be turned off by opening and closing the secondary circuit 2. Without altering the main circuit 1 circuit, the main circuit 1 can be remotely shut off by adding the secondary circuit 2. After actual production, by adding the secondary circuit 2 to the existing circuitry, the power to the vehicle's electrical systems 11 can be cut off from the driver's cab, allowing the driver to conserve battery power.

[0033] In a preferred embodiment of this invention, one end of the return spring is connected to the contact point, and the other end is connected to the outer casing. When the return spring is in its natural state, the contact point is in an open state.

[0034] In a preferred embodiment of this invention, the vehicle electrical components 11 of the commercial vehicle are located on the main circuit 1; one end of the secondary circuit 2 is connected between the positive power supply of the commercial vehicle and the BCM4, and the other end is connected to the negative power supply.

[0035] Specifically, the main circuit 1 controls the switch 3 of the vehicle's electrical system 11. However, even when the vehicle is parked, a small number of low-power electrical appliances still consume power, which is why the battery is depleted during prolonged parking. These low-power electrical appliances include the BCM4 and the dome light power supply, forming a circuit with the main power supply. The secondary circuit 2 is connected between the positive terminal of the main power supply and the BCM4. When the secondary circuit 2 is disconnected, current does not flow through other electrical appliances in the vehicle, thus de-energizing and shutting down their main circuits.

[0036] In a preferred embodiment of this invention, the secondary circuit 2 includes a switch 3, the main power switch 321 for the driver's cab. Specifically, the switch 3, the main power switch 321 for the driver's cab, is located on the center console of the driver's cab for easy power disconnection by the driver.

[0037] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
