Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 1 and 2, a first preferred embodiment of the vehicle of the present invention is an electric motor vehicle comprising: a vehicle body 1, a load sensor 2, a power unit 3, and a battery 4.

The vehicle body 1 includes a vehicle body 11, a seat cushion 12 disposed on the vehicle body 11, at least two wheels 13, and a control member 14 for controlling the rotational speed of the wheels 13. The control member 14 is generally designed on the right side of the vehicle body 1 and can be held and rotated by the right hand of the locomotive knight to change the vehicle speed. In an electric motor vehicle, the control member 14 is typically a control handle.

The load sensor 2 is mounted on the vehicle body 1 for detecting the weight carried by the vehicle body 1 and transmitting a first sensing signal when the weight is less than a basic weight value. And sending a second sensing signal when detecting that the weight is greater than or equal to the basic weight value. The load sensor 2 of the present embodiment can measure the strain of the seat cushion 12 after being subjected to the force, and further convert the weight carried on the seat cushion 12. There are many ways to measure strain, including optical, electronic, mechanical and other measurement methods. Specifically, the load sensor 2 of the embodiment is a load cell that can be mounted on the bottom of the seat cushion 12 or mounted on the periphery of the seat cushion 12 to fit the load weight sensor 2 . The position of the load sensor 2 is adjacent to the seat cushion 12. The principle of the load cell is mainly: when the metal wire is long When the degree is changed, the resistance value also changes. Therefore, when the load cell is measured, a plurality of strain gauges (Strain Gage) containing a metal material are attached to the seat cushion 12, and the seat cushion 12 is used. After the force is applied, the bending stress is generated, and the resistance values of the plurality of strain gauges are also changed, and the voltage generated by the circuit composed of the plurality of strain gauges is also changed, so that the voltage can be obtained by measuring the voltage. The amount of stress that the seat cushion 12 is subjected to is converted into the weight that the seat cushion 12 is subjected to. The load sensor 2 is not limited to the load cell of the embodiment. The load sensor 2 can also utilize other structures and measurement principles as long as it can be used to measure the load and transmit signals to the power unit 3.

The power unit 3 signals the control unit 14 and the load sensor 2, and can be controlled by the control unit 14 to drive the wheels 13 to rotate and change the rotational speed of the wheels 13. The power unit 3 can receive the signal from the load sensor 2, and after receiving the first sensing signal from the load sensor 2, the power unit 3 cannot drive the wheels 13 to rotate. Specifically, the power unit 3 of the present embodiment includes a motor controller 31 connected to the control member 14 and the load sensor 2, and a signal connected to the motor controller 31 and capable of driving the wheels 13 to rotate. Motor 32. After receiving the second sensing signal, the motor controller 31 controls the motor 32 to be controlled by the control member 14 to change the rotational speed, so that the rotational speed of the wheels 13 can be changed. However, after the motor controller 31 receives the first sensing signal, the motor 32 is controlled to be disabled, so that the motor 32 cannot drive the wheels 13 to rotate.

The battery 4 is mounted on the vehicle body 1 for providing the load sensor 2 and the power required for the operation of the power unit 3.

When the invention is used, the weight of the occupant on the seat cushion 12 is mainly detected by the load sensor 2. In this embodiment, the basic weight value can be set to 35 kg, but this is merely an example and is not limited thereto. Since the weight of the average adult is greater than the basic weight value, when the load sensor 2 detects that the weight on the seat cushion 12 is greater than the basic weight value, it indicates that an adult is sitting on the locomotive, and the load sensor 2 That is, the second sensing signal is transmitted to the motor controller 31. At this time, the locomotive of the present invention is in a free riding state, and in this state, the locomotive rides and controls in the same manner as the general locomotive, The control member 14 is rotated to control the rotational speed of the motor 32, thereby changing the rotational speed of the wheels 13.

However, when the load sensor 2 detects that the weight on the seat cushion 12 is less than the basic weight value, only the child may sit on the seat cushion 12 at this time, because the child's weight is lighter than the basic weight. The weight value, or no one has been seated on the seat cushion 12. At this time, the load sensor 2 sends the first sensing signal to the motor controller 31 to control the motor 32 to be strictly disabled, so that the locomotive is in a safe protection state. In this state, even if the control member 14 is rotated, the motor 32 cannot be driven to operate, and the rotation of the wheels 13 cannot be driven. In the safety protection state, the locomotive can be designed to be unfired, and the second sensing can be re-issued until the load sensor 2 detects that the weight on the seat cushion 12 is greater than the basic weight value. The signal causes the locomotive to return to the free riding state.

Therefore, when the locomotive is stopped and not turned off, if only the child is sitting on the locomotive, the locomotive will automatically switch to the safety protection state due to the insufficient weight on the seat cushion 12, even if the child turns the control member 14 and also It is not possible to control the operation of the motors 32 and the wheels 13, which are constantly stationary in place, thereby avoiding accidental disasters.

It should be noted that the load sensor 2 can be configured to periodically perform load measurement, and send a signal to the power unit 3 according to the measurement result at any time, so as to control the operation state of the power unit 3 according to the load condition at any time.

In summary, by providing the load sensor 2 to measure the load weight on the seat cushion 12, the rotation of the wheels 13 can be automatically prohibited from being driven when the load weight is insufficient, so that the vehicle is always at the same place. The invention has the function of sensing weight, can improve safety, prevent accidental disasters, and achieve the object of the present invention.

Referring to Fig. 3, a second preferred embodiment of the vehicle of the present invention is an oil locomotive. The following mainly describes the difference between this embodiment and the first preferred embodiment.

The power unit 3 of the embodiment includes an engine 33. After the power unit 3 receives the second sensing signal of the load sensor 2, the locomotive is in the free riding state, and the control part of the locomotive at this time The control function of 14 and the overall riding and control mode of the locomotive are the same as those of the general locomotive. After the power unit 3 receives the first sensing signal of the load sensor 2, it indicates that only a light weight child is riding on the locomotive, or no one is riding, and the engine 33 is automatically turned off, and The locomotive is placed in this safe state.

Therefore, in this embodiment, when the engine 33 is in the safe protection state by the engine 33 being turned off, the control member 14 is not transferred. Move forward and move forward to achieve security protection. Moreover, the fuel locomotive of the present embodiment can be automatically extinguished, which can reduce carbon emissions and contribute to environmental protection. When the locomotive detects the load weight again and reaches the basic weight, the locomotive can be automatically started, and the safety state can be automatically returned to the free riding state.

Based on the above description, the present invention does not need to limit the power source of the vehicle, the outer shape and the detailed structure of the vehicle, as long as the load sensor 2 can be installed on the vehicle, and thereby the operation of the power unit 3 can be controlled. The state is the protection scope of the present invention. For example, the scooter for the elderly or the disabled can also be used. The number of wheels of such a vehicle may be three, four or other quantities, and some scooters are used to drive the wheels. The control member 14 that is rotated 13 is in the form of a button, so that the operation of the control member 14 is not limited in the practice of the present invention.

Referring to FIG. 1 and FIG. 2, the structure of the third preferred embodiment of the vehicle of the present invention is substantially the same as that of the first preferred embodiment. The difference is that the present embodiment automatically forces the motor 32 when the vehicle is overloaded. The operation is prohibited. Therefore, the load sensor 2 of the embodiment sends the first sensing signal when detecting that the weight carried by the vehicle body 1 is greater than an overweight weight value, so that the power unit 3 receives the After the first sensing signal, the wheels 13 cannot be driven to rotate. When it is detected that the weight carried by the vehicle body 1 is less than or equal to the weight of the overweight, the vehicle can automatically return to the state of being freely rideable. In this embodiment, the operation modes are the same except that the condition for issuing the first sensing signal is different from that of the first preferred embodiment.

This embodiment automatically detects when the weight of the load is detected to be overweight. It is forbidden to rotate the wheels 13 to avoid the damage of the vehicle when the load is too heavy or the risk of being easily damaged. Therefore, the design of the embodiment also contributes to the improvement of driving safety. Moreover, in addition to the load on the seat cushion 12, the load detection can also detect the load of the entire vehicle, and automatically prohibit the vehicle from advancing as long as the load is too heavy.

It should be noted that, in this embodiment, when the weight of the load is greater than the weight of the overweight, the first sensing signal is sent, and the detected weight of the first preferred embodiment is less than the basic weight. The function combination of the first sensing signal is issued, so that the vehicle of the present invention can forcibly stop the advancement whether the load is insufficient or the load is too heavy. The overweight weight value is greater than the base weight value, and the magnitude of the overweight weight value can be set differently depending on various vehicle types. For example, the locomotive of 50c.c. can carry less than 125c.c. locomotive, therefore, the overweight weight value set for 50c.c. locomotive is usually less than 125c.c. locomotive's overweight weight value. In addition, taking the electric motor vehicle carried by the double as an example, the excess weight value is about 150~200Kg, and the excess weight value is determined according to the maximum torque that the power unit 3 of the locomotive can provide and the maximum load that the tire can bear. Exceeding the weight value that the vehicle can withstand may cause the load on the power unit 3 and the risk of puncture.

In addition, the overweight prohibition forward function of the embodiment can also be applied to various types of vehicles. For example, when applied to a fuel locomotive, the power unit 3 includes an engine, and when the power unit 3 receives the load sensor 2 After a sensing signal, the engine will automatically turn off. This mode of operation is similar to the second preferred embodiment except that the engine is off.

Further, the power unit 3 of the embodiment can adjust the output power according to the weight detected by the load sensor 2, that is, the power unit 3 can automatically adjust and drive the wheels according to the weight of the load. The force of the drive unit 13 of the power unit 3 is greater as the load is greater.

According to the foregoing embodiments, the spirit of the present invention is mainly that the load sensor 2 is configured to detect the weight carried by the vehicle body 1 and the weight carried by the vehicle body 1 does not fall to a standard weight. When the range is within, the first sensing signal is sent to force the vehicle to prohibit the advancement. For example, the average adult weighs about 40 kg or more, and the minimum value of the standard weight range can be set to about 35 to 40 kg. Depending on the model, such as single-load and dual-load locomotives, there are different overweight weight values. Taking a double-loaded locomotive as an example, the weight of the overweight is about 150~200 kg, and the standard weight range of the locomotive can be set between 35 and 200 kg; but this is only an example. In fact, the standard weight range of different models can be different. Settings. In the first and second preferred embodiments, it is mainly when the vehicle load is too light (the load is less than the standard weight range) prohibiting the advancement; in the third preferred embodiment, when the load is too heavy (the load is greater than the standard) The weight range is prohibited from advancing, and it is also disclosed in the third preferred embodiment that the function of prohibiting the advancement of the overweight and the underweight may be combined. Specifically, the lower limit of the standard weight range corresponds to the basic weight value of the first and second preferred embodiments, and the upper limit of the standard weight range corresponds to the excess weight value of the third preferred embodiment. When the vehicle body 1 load falls within the standard weight range, the vehicle is controlled and operated in the same manner as the existing vehicle.

In the case that the vehicle is prohibited from moving too light or too heavy, the load sensor 2 then detects that the weight carried by the vehicle body 1 falls within the standard weight range. The test signal is given to the power unit 3, and after receiving the second sensing signal, the power unit 3 can subsequently control the wheels 13 to operate. In the first preferred embodiment of FIGS. 1 and 2, after the power unit 3 is unable to drive the wheels 13 to rotate, the load sensor 2 detects the weight carried by the vehicle body 1. When falling within the standard weight range, the second sensing signal is sent to the motor controller 31, and the motor controller 31 controls the motor 32 to be received after receiving the second sensing signal. The control of the control member 14 changes the rotational speed.

Referring to Figure 4, a fourth preferred embodiment of the vehicle of the present invention is a vehicle comprising: a body 1, a load sensor 2, and a power unit not shown. The interior 1 of the car includes a driver's seat 15 and a console 16, such as the engine's engine and the like. The load sensor 2 of the present embodiment is mainly installed at the bottom or the periphery of the driver's seat 15, and can be used to detect the weight carried by the driver's seat 15. In this embodiment, when the weight carried by the driver's seat 15 does not fall within the standard weight range, the first sensing signal is sent to force the car to prohibit the advancement by the control of the driving computer. Therefore, when the load of the driver's seat 15 is too light, it means that there is no one on the driver's seat 15 or a child, and even if the accelerator is depressed, the car cannot be driven forward.

However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto. The simple equivalent changes and modifications made by the patent scope and the contents of the patent specification are still within the scope of the invention.
