Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

Example 1:

as shown in fig. 1 to 6, the present embodiment provides a protection system for an electric vehicle with a driver's position detection function, which includes a vehicle body 1, where the vehicle body 1 is a normal electric vehicle, and the vehicle body 1 has a seat 2, where the seat 2 in the present embodiment is the most important modified component. The automobile body 1 is provided with a controller 3 and a relay 4, the controller 3 is a 51 single-chip microcomputer controller, and the controller 3 and the relay 4 are arranged at the position of a vehicle head. And the relay 4 is used for controlling the connection and disconnection between the motor of the vehicle body 1 and a power supply wiring circuit. The sensor 5 is arranged at the bottom of the seat 2, and the sensor 5 is used for detecting whether a driver sits on the seat of the electric vehicle. In this embodiment, the relay 4 and the sensor 5 are both electrically connected to the controller 3, that is, the controller 3 is configured to receive an electrical signal from the sensor 5 and control the action of the relay 4 to control the rotation of the motor. Preferably, the sensor 5 is a touch sensor. After a driver sits down, the saddle 2 deforms under the weight of the driver, so that triggering of the contact sensor is achieved, the contact sensor transmits a signal of sitting of the driver to the controller 3, the controller 3 controls the relay 4 to be connected with a circuit, and the motor is powered by the storage battery to move forwards. When a driver is not seated on the seat 2, the sensor 5 cannot be triggered, i.e., cannot transmit a signal to the controller, and the relay 4 controls the motor line to be in an open state.

Example 2:

for embodiment 1, the sensor 5 in this embodiment is a load cell. When the weighing sensor detects that the weight exceeds 30kg, the controller 3 controls the relay 4 to switch on the motor circuit of the vehicle body 1. By setting the controller 3, only when the weighing sensor detects that the weight of the driver exceeds 30kg, the relay 4 can be controlled to switch on the motor circuit of the electric vehicle, so that the safety accident of the electric vehicle driven by a light child can be prevented.

Example 3:

in the embodiment 2, a new electric vehicle seat to which the system is applied is designed. The seat 2 comprises a seat surface 21, a support 22, an installation plate 23 and a sleeve 24, wherein the seat surface 21 is made of soft materials, and the bottom surface of the seat surface 21 is made of injection molding materials. The bracket 22 is fixedly mounted at the bottom of the seat surface 21 through bolts. A plurality of sliding shafts 25 are welded on the support 22, a plurality of sliding barrels 26 corresponding to the sliding shafts 25 one to one are mounted on the mounting plate 23, the sliding shafts 25 are in corresponding matching sliding connection with the sliding barrels 26, the limiting heads are fixed at the bottoms of the sliding shafts 25 through bolts, the diameters of the limiting heads are larger than those of the sliding barrels 26, and the support 22 can be prevented from being loosened in the sliding barrels 26. The sliding shaft 25 is sleeved with a spring 27, the top of the spring 27 is fixedly connected with the bottom surface of the support 22, and the bottom of the spring 27 is fixedly connected with the top surface of the mounting plate 23. The bottom of the support 22 is welded with a contact bulge 28, the sensor 5 is fixed on the top surface of the mounting plate 23 through bolts, the contact bulge 28 corresponds to the sensor 5, and the sleeve 24 is welded at the bottom of the mounting plate 23. When a driver is seated on the seat, the driver presses the seat surface 21, the seat surface 21 slightly sinks through the cooperation of the sliding shaft 25 and the sliding barrel 26, the bracket 22 presses the spring 27, the contact protrusion 28 is contacted with the load cell along with the pressing of the seat surface 21, and the weight of the driver is measured through the load cell. The weighing sensor transmits a signal to the controller 3, the controller 3 can judge the weighing weight, and the controller 3 controls the relay 4 to be electrified after the weighing weight reaches a set rated value. This saddle 2 stable in structure triggers high-efficiently, can guarantee effectively whether the judgement to driver's position, driver weight.

Example 4:

for embodiment 2, in this embodiment, the device is applied to an electric vehicle with an integrated seat, and the load cell is disposed under the leather surface of the seat and just above the load cell after the driver sits on the seat. The weight of the driver is weighed by a weighing sensor, and when the weighing sensor detects that the weight exceeds 30kg, the controller 3 controls the relay 4 to switch on the motor line of the vehicle body 1. By setting the controller 3, only when the weighing sensor detects that the weight of the driver exceeds 30kg, the relay 4 can be controlled to switch on the motor circuit of the electric vehicle, so that the safety accident of the electric vehicle driven by a light child can be prevented.

Example 5:

with respect to any of embodiments 1 to 4, the system in this embodiment can be applied to any three-wheeled or four-wheeled electric vehicle.

Example 6:

according to any one of embodiments 1-5, an audible and visual alarm can be added on one side of a controller of the electric vehicle, the audible and visual alarm is connected with the controller, when the vehicle stops, a driver leaves a seat, the weighing sensor detects that the driver leaves, if the vehicle is not powered off at the moment, the controller controls the audible and visual alarm to give out audible and visual alarm, or words such as 'please turn off the power supply' recorded in advance are played, so that the electric energy waste caused by the fact that the vehicle is not powered off after the driver leaves or the vehicle is stolen and ridden by others is prevented.
