[0042] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0043] Figure 1 1 is a schematic diagram of a device 100 for preventing an electric vehicle from accidentally starting. Figure 1 As shown, the device includes a controller, a weight sensor, and an ignition switch.

[0044] Figure 2 Schematic diagram of a weight sensor. Figure 2 As shown, the weight sensor includes a lever and a first sensor.

[0045] Figure 3 A schematic diagram of a lever.

[0046] The first sensor includes a first switch, and the first switch is arranged at a first position.

[0047] The first end of the lever is arranged under the electric vehicle seat, and the first end descends based on the weight of the electric vehicle seat and drives the second end to rise; when the weight on the electric vehicle seat reaches a first weight, the second end rises to a first position, and the weight sensor sends a first signal to the controller.

[0048] The weight sensor sending the first signal to the controller includes: when the second end of the lever rises to the first position, the second end toggles the first switch, thereby triggering the first sensor to send the first signal to the controller.

[0049] If the ignition switch is closed and the controller receives the first signal, the controller controls the motor of the electric vehicle to unlock.

[0050] Based on the above solution, the electric vehicle can only be started when the weight on the electric vehicle seat reaches or exceeds the first weight, thereby preventing minors from accidentally starting the electric vehicle.

[0051] For example, the first weight may be set to 45 kg, which is the weight of an adult.

[0052] Optionally, the first weight may be preset at the factory or may be user-defined.

[0053] Optionally, if the ignition switch is closed and the controller receives the first signal, the controller controls the motor of the electric vehicle to unlock, including: after the controller receives the first signal for a first time period, the controller controls the motor of the electric vehicle to unlock.

[0054] Based on the above solution, the electric vehicle can only be started when the weight on the electric vehicle seat reaches or exceeds the first weight and after a period of time has passed, thereby preventing the electric vehicle from starting before the user is seated firmly.

[0055] In certain implementations, when the motor of the electric vehicle is unlocked, the controller controls the maximum output power of the motor to be the first power.

[0057] In some implementations, the device 100 further includes a second sensor, the second sensor includes a second switch, and the second switch is disposed at a second position.

[0058] When the weight on the electric vehicle seat reaches a second weight, the second end rises to a second position, and the weight sensor sends a second signal to the controller, wherein the second weight is greater than the first weight, and the second position is higher than the first position.

[0059] The weight sensor sending the second signal to the controller includes: when the second end of the lever rises to the second position, the second end toggles the second switch, thereby triggering the second sensor to send the second signal to the controller.

[0060] If the controller receives the second signal after receiving the first signal, the controller controls the maximum output power of the motor to be a second power, and the second power is greater than the first power.

[0061] Based on the above scheme, if the weight on the electric vehicle seat is large, it means that the driver is heavy or carries a lot of items. At this time, a larger driving power is needed to make the electric vehicle run smoothly.

[0062] In some implementations, if the controller receives a second signal after receiving the first signal, the controller controls the maximum output power of the motor to be the second power, including: after the controller receives the second signal for a second period of time, the controller controls the maximum output power of the motor to be the second power.

[0063] Based on the above solution, when the weight on the electric vehicle seat reaches or exceeds the second weight and after a period of time, the electric vehicle increases the maximum output power to avoid increasing the maximum output power before the passenger sits firmly.

[0064] In some implementations, the device 100 further includes a third sensor, the third sensor includes a third switch, and the third switch is disposed at a third position.

[0065] When the weight on the electric vehicle seat reaches a third weight, the second end rises to a third position, and the weight sensor sends a third signal to the controller, wherein the third weight is less than the first weight, and the third position is lower than the first position.

[0066] The weight sensor sending the third signal to the controller includes: when the second end of the lever rises to the third position, the second end toggles the third switch, thereby triggering the third sensor to send the third signal to the controller.

[0067] If the controller receives the third signal, the controller controls the motor to remain locked.

[0068] Based on the above scheme, when the weight on the electric vehicle seat is less than the first weight, it means that the driver is underweight. At this time, the electric vehicle may be operated by a minor. At this time, the electric vehicle should be kept locked to prevent minors from accidentally starting the electric vehicle.

[0069] In some implementations, the device further includes a warning device, and if the controller receives the third signal, the controller further controls the warning device to emit a sound indicating insufficient weight.

[0070] Optionally, the controller also controls the warning device to issue a visual indication, such as a flashing light.

[0072] In some implementations, the device 100 further includes a fourth sensor, the fourth sensor includes a fourth switch, and the fourth switch is disposed at a fourth position.

[0073] When the weight on the electric vehicle seat reaches a fourth weight, the second end rises to a fourth position, and when the second end rises to the fourth position, the weight sensor sends a fourth signal to the controller; wherein the fourth weight is greater than the first weight, and the fourth position is higher than the first position.

[0074] The weight sensor sending the fourth signal to the controller includes: when the second end of the lever rises to the fourth position, the second end toggles the fourth switch, thereby triggering the fourth sensor to send the fourth signal to the controller.

[0075] If the controller receives the fourth signal within the third time period after receiving the first signal, the controller controls the motor to remain locked.

[0076] Based on the above scheme, when the weight on the electric vehicle seat reaches or exceeds the third weight, it means that the electric vehicle is overweight. At this time, the electric vehicle should be locked to prevent the electric vehicle from driving with overweight.

[0077] In some implementations, the device further includes a warning device, and if the controller receives the fourth signal, the controller further controls the warning device to emit a sound indicating overweight.

[0078] Based on the above scheme, when the electric vehicle is overweight, an alarm should be sounded to allow the driver to reduce the items he carries.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
