Description

Seating detection system, seat cushion group, frame, front intelligent part, burglar alarm, controller and electric vehicle
Technical Field
Belong to electron technical field, concretely relates to electric motor car electrical components.
Background
For convenience of description, the present invention defines the following terms:
"adapter" refers to a part for collecting electrical components in a certain area, especially directly inserted on a circuit board, and the part is called "electrical adapter";
the intelligent parts in front of the vehicle comprise an adapter with a mcu chip for communication, a combination instrument (also called a gauge head) or a combination headlamp (also called a headlamp assembly or a lamp cap);
"Accelerator" means a component for controlling the speed of an electric vehicle, including a handlebar of a small vehicle and a foot accelerator of a large vehicle;
"vehicle control component" refers to electrical components controlling the operation of the electric vehicle, such as an accelerator, a brake switch, an electric door lock, an anti-theft alarm, etc.;
"burglar alarms" are sometimes referred to simply as alarms;
"Motor controller" is sometimes simply referred to as a controller;
the 'seat cushion group' refers to a seat cushion, a seat board, a seat cover, a seat, a bracket and the like in the area of the driving cab;
"vehicle front controller associated electrical appliance" refers to electrical appliances at the front of the vehicle associated with the controller, such as: electric door lock, brake switch, reversing switch, gear switch, repair switch, rotating handle or pedal accelerator plate, instrument, etc.;
the electric vehicle refers to a vehicle with batteries as power, such as a four-wheel electric vehicle, an electric bus, an electric sightseeing vehicle, an electric sweeper, an electric forklift, a baby carriage, an electric bicycle, an electric moped, an electric motorcycle, an electric tricycle and the like.
Once a traditional electric vehicle is opened by a power door or a remote control, or pushed, or a child is curious on the vehicle, the electric vehicle is out of control and runs out of control if a driver does not effectively control the electric vehicle due to mistaken collision of a rotating handle or a pedal accelerator, the electric vehicle is commonly called as an overtaking vehicle, and the electric vehicle can collide with pedestrians or fall out of passengers on the vehicle, particularly the old and the child are most dangerous, so that serious accidents are caused.
In the existing two-wheel three-wheel electric vehicle, the rotating handle is positioned at the outermost side of the handlebar, and is the most easily touched place by mistake. Still another fatal problem is that when the vehicle is flying, a person who originally moves the vehicle wants to stabilize the vehicle, the person grips the handlebar and instinctively pulls the handlebar backwards, which is just the operation of accelerating the torsion, and the electric vehicle flies harder. Vicious feedback, accident moment!
In order to solve the problem, a P-gear switch is additionally arranged on the conventional electric vehicle, and the electric vehicle can be moved only by pressing the electric vehicle after being started. However, after that, the driver gets off the vehicle for temporary handling and does not shut down the vehicle or forgets to shut down the vehicle, and passengers or people moving down the vehicle can run around the vehicle as soon as the accelerator is touched. Even if the driver is not on the vehicle, the vehicle can fly when the driver accidentally moves the vehicle and collides the vehicle.
This is the serious potential safety hazard that current electric motor car exists.
Disclosure of Invention
The purpose of the invention is as follows: even if the above potential safety hazards are solved.
The technical route of the invention is that a seat detection device is additionally arranged in a driving platform area to detect the state of a driver seat, the vehicle can be driven only when the driver is on the seat, and the vehicle can not move as long as the driver leaves the vehicle. It is safe even if an accelerator is encountered. Technically, the danger of galloping is completely eliminated, and the safety of pedestrians or passengers is ensured.
Seating detection system
The system includes a seating detection device and a motor controller. The seating detection device is directly or indirectly connected with the motor controller.
The seating detection device is used for detecting whether a driver of the electric vehicle sits on a driving seat or not and outputting a corresponding signal to the motor controller. The application of the seating detection device is the core of the invention.
If the driver does not sit on the driver seat, the electric vehicle is stopped because the motor controller cannot obtain a normal signal, and the electric vehicle is not started even if the accelerator is touched. Only when a driver sits on the driver seat, the vehicle can normally drive, and the safety of passengers and pedestrians is ensured. This is the object of the present invention.
The seating detection system is divided into a bus control seating detection system and a special line control seating detection system. The total number of the products is 2, and only one of the products is selected from actual products.
The seating detection device is classified into a contact type and an induction type. The total number of the products is 2, and only one of the products is selected from actual products.
The contact seating detection device includes a contact switch.
The contact switch is arranged in the area of the driver's cab and presses the switch contact to act according to the pressure of the driver sitting down.
The contact switch is loosened by the elasticity of the contact switch or the elasticity of a nearby external spring or elastic sheet and closed by the extrusion of the gravity of the driver sitting down, so that the state of the driver is detected.
The contact switch only needs 2 wires, and is mostly mechanical. The most common contact switches are push-button switches and travel switches. The travel switch is also called a microswitch. See fig. 11, 12, 13, 14, which are all physical photographs. The contact switch is flexible to use and low in manufacturing cost, but has the defects of contact, easiness in influence of dust, grease and oxidation and short service life.
The contact switch is classified into a normally open type and a normally closed type.
The normally open type is that the driver is in a disconnected state and is not powered on when not sitting down, and is powered on when sitting down.
The normally closed type is a type in which a driver is in a conducting state when not seated and is disconnected when seated.
The electrical parameters, such as strain gauge sensors, are also changed by mechanical deformation stress caused by the gravity extrusion of the driver sitting down, so that the state of the driver is judged according to the electrical parameters, and the device also belongs to the category of contact type seating detection devices. This is a special case of a touch switch. The signal output of the strain gauge belongs to the contact category because the change of the resistance of the strain gauge caused by mechanical pressure. And finally, judging the seat state of the driver according to the resistance of the seat.
The induction type seating detection device includes a sensor.
The sensor comprises a proximity switch, ultrasonic waves, infrared rays, laser, a Hall sensor and the like. Most of these sensors are active, require a power supply internally, and have dedicated circuitry. Its advantages are no contact point, high sealing performance and long service life. The disadvantages are high cost and power consumption.
Wherein, the approach switch is most reliable and the purchase is most convenient. See fig. 15 and 16, which are physical photographs. Proximity switches are classified into an inductive type, a capacitive type, a photoelectric type, a hall type, and the like. The proximity switch body is fixed, for example on the fixed frame, and the other end is its sensitive thing, for example the iron sheet of bedplate, as long as the mutual distance is less than a certain rated value, its output then overturns. The external connection line is divided into 2 lines, 3 lines and 4 lines. Detailed description of related applications
Ultrasonic, infrared, laser are also good options. Both reflection and blocking can be achieved. If the chair back is arranged in the seat and the chair back adopts a reflection mode, the chair armrests are arranged in the left and right seat and the chair armrests adopt a correlation mode. These may purchase the corresponding modules. The pyroelectric infrared human body sensor is convenient, the top of the driving cab can be installed, and the output of the sensor can be used for stopping the controller as long as a driver is not in the sensing range.
Hall sensors may also be used to detect the condition of the operator's seat cushion set.
The sensor is arranged in the area of the driver's seat, and outputs different signals corresponding to different states of the driver according to the extrusion, blocking or induction of the driver. The sensor is connected with a mcu circuit, software processing is needed, the ADC conversion and digital filtering are included, and the mcu of the front intelligent part or the motor controller is used for processing the sensor signal and judging the state of a driver. Such as ultrasonic, infrared, laser, hall sensor applications.
The bus control seating detection system is applied to the connection of an intelligent component in the front of a vehicle and a controller behind the vehicle through a communication line and exchanges data. The bus control seating detection system comprises a vehicle front intelligent component, a communication line, a motor controller, a seating detection device and a vehicle control component.
The vehicle control component comprises an accelerator, a brake switch or an electric door lock. As these are all the signals required by the motor controller.
The intelligent parts pass through communication line connects motor controller and exchange data, and some communication lines still pass through detection device that sits.
The intelligent vehicle front component is connected with the seating detection device and transmits a detected signal to the motor controller through a communication line, or the seating detection device directly controls the on-off of the communication line.
If the driver is not seated in the driver's seat, the motor controller is stopped because a normal signal is not obtained or communication is interrupted. This is the working principle of the seating detection system.
The bus control seating detection system is divided into 5 types: bus type A, bus type B, bus type C, bus type E, and bus type F.
The bus A type comprises a vehicle front intelligent component, a communication line, a seating detection device and a motor controller. The motor controller is connected with the intelligent vehicle front component through the seating detection device.
The seating detection device controls the on-off of the communication line, and if a driver does not sit on the driver seat and cuts off the communication signal, the motor controller cannot obtain a normal communication signal and stops the vehicle.
The bus B type comprises a vehicle front intelligent component, a communication line, a seating detection device and a motor controller. The motor controller is connected with the intelligent vehicle front component through the communication line. The seating detection device is connected with the intelligent component in the front of the vehicle and transmits signals.
If the driver does not sit on the driver seat, the intelligent part in front of the vehicle can not obtain normal seat signals, and a shutdown command is sent to the motor controller through the communication line.
At this time, the intelligent front vehicle component needs to add a separate socket to connect with the plug of the seating detection device. This and the type of switch and sensor selected for use will have different outlet and appliance signals.
The bus C type comprises an intelligent vehicle front component, a communication line, a seating detection device, a motor controller and an accelerator. The motor controller is connected with the intelligent vehicle front component through the communication line. The accelerator is connected with the intelligent part in the vehicle front through the seating detection device and transmits signals.
If the driver does not sit in the driver's seat and the accelerator signal is cut off, the in-vehicle intelligent component sends a 0 accelerator signal to the motor controller to stop. The 0 accelerator signal corresponds to a forced neutral.
The bus D type comprises a vehicle front intelligent component, a communication line, a seat entering detection device, a motor controller and an electric door lock. The motor controller is connected with the intelligent vehicle front component through the communication line. The electric door lock is connected with the intelligent part in the vehicle through the seating detection device and transmits signals.
If the electric door lock signal is turned off without the driver sitting in the driver's seat, the in-vehicle intelligent component sends a shutdown command to the motor controller. The controller is applied to the communication line and the controller startup line, and the controller does not need a special startup line, namely a traditional locking line.
The electric door lock can also be directly connected with the motor controller, and if a driver does not sit on a driver seat and cuts off a lock wire outlet signal, the motor controller stops because of no power supply. This is a conventional use, with the lock out line used to provide power for the internal operation of the controller. The controller has no power supply and certainly cannot start the motor.
The bus E type comprises a vehicle front intelligent component, a communication line, a seating detection device, a motor controller and a brake switch. The motor controller is connected with the intelligent vehicle front component through the communication line. The brake switch is connected with the intelligent vehicle front component through the seating detection device and transmits signals.
If the driver does not sit in the driver's seat and turns on the brake signal, the in-vehicle intelligent component sends a brake command to the motor controller to stop. Note that a normally closed switch or sensor is required here, as opposed to the previous application. The closed switch or the sensor is connected in parallel with the brake switch. If the driver does not sit on the driver seat, the seating detection device generates a braking signal.
The special line control seating detection system is applied to an intelligent part without a vehicle front, and a vehicle front controller related electric appliance is connected with a vehicle rear controller through a special wire. The special line control seating detection system comprises a motor controller, a seating detection device and a vehicle control component. The vehicle control component comprises an accelerator, a brake switch, an electric door lock or an anti-theft alarm.
If the driver is not seated in the driver's seat, the motor controller is stopped because a normal signal is not obtained. The basic working principle of the special line control seating detection system is shown.
The special line control seating detection system is divided into 5 types: type A, type B, type C, type E and type F.
The special line A type comprises a seating detection device and a motor controller. The motor controller is connected with the seating detection device. If the driver is not seated in the driver's seat, the motor controller does not detect a normal seating detection device signal and stops.
At this time, the motor controller needs to add a separate socket to connect the plug of the seating detection device. This and the type of switch and sensor selected for use will have different outlet and appliance signals.
The special line B type comprises an electric door lock, a seat entering detection device and a motor controller. The motor controller is connected with the seating detection device, and the seating detection device is connected with the electric door lock of the vehicle.
And if the driver does not sit on the driver seat, the motor controller stops because the normal electric door lock output signal is not obtained. That is, there is no normal line power supply locked, and the controller cannot work.
The special line C type comprises a seating detection device, a motor controller and an accelerator. The motor controller is connected with the seating detection device. The accelerator is connected with the seating detection device and transmits signals.
If the driver does not sit in the driver's seat and the accelerator signal is cut off, the motor controller is stopped by receiving the 0 accelerator signal. The 0 accelerator signal corresponds to a forced neutral.
The special line D type comprises a seating detection device, a motor controller and an anti-theft alarm. The motor controller is connected with the seating detection device. The anti-theft alarm is connected with the seating detection device and transmits signals.
If the driver does not sit on the driver seat and the output signal of the burglar alarm is cut off, the motor controller stops due to the fact that the normal burglar alarm signal is not obtained. Because the normal operation of the controller requires the burglar alarm to output a nominal signal, typically 1 level.
The special line E type comprises a seating detection device, a motor controller and a brake switch. The motor controller is connected with the seating detection device. The brake switch is connected with the seating detection device and transmits signals.
If the driver does not sit on the driver seat and the brake signal is switched on, the motor controller is triggered to brake and stop. Note that a normally closed switch or sensor is required here, as opposed to the previous application. The driver does not sit on the driver seat, and the seating detection device generates a braking signal.

Detailed Description
In the following embodiments, the "normally open" and "normally closed" switches labeled in the drawings of the specification refer to not only contact type mechanical switches, but also to the "normally open" and "normally closed" outputs of the inductive sensor and the contact outputs of the application circuit thereof, for example, the output of the inductive sensor drives a relay.
The introduction of seating detection means is the core of the present invention. The seating detection device is completed by components such as a contact switch and an induction sensor.
The most common contact switches are push-button switches and travel switches. The travel switch is also called a microswitch. See fig. 11, 12, 13, 14, which are all physical photographs. There are other various forms of contact switches. The working principle of the device is that the pressure of a driver sitting down is used for triggering the action of the switch. Therefore, the contact switch is arranged at a convenient place of the driver's cab area, and a driver can press the contact switch when sitting down and flick the contact switch when leaving, so that the action of the contact switch is only caused. The contacts of the switches are used to control the signals necessary for the motor controller to work.
The most common inductive switches are proximity switches. It is most reliable and convenient to purchase. See fig. 15 and 16, which are physical photographs. There are other various forms. Proximity switches are classified into an inductive type, a capacitive type, a photoelectric type, a hall type, and the like. The most common is the inductive type. The proximity switch body is fixed, for example on the fixed frame, and the other end is its sensitive thing, for example the iron sheet of bedplate, as long as the mutual distance is less than a certain rated value, its output then overturns. The capacitive type sensitive object is metal, the photoelectric type is reflected or shielded, and the Hall type sensitive object is magnet. The external lines of the proximity switch are divided into 2 lines, 3 lines and 4 lines. See the relevant application specification for details. In addition, ultrasonic wave, infrared, laser, hall, etc. are also optional. The pyroelectric infrared human body sensor is convenient, and the output of the pyroelectric infrared human body sensor can be used for stopping the work of the controller as long as a driver is not in the sensing range of the pyroelectric infrared human body sensor.
A button switch can be placed in the seat cushion and the seat cover, and a travel switch, a button switch, a proximity switch or other sensors can be placed between the seat cushion, the seat cover and the seat plate or between the seat plate and the bracket to detect the state of the driver seat.
The mechanical structure of the seating detection device needs to protect a sensor or a switch, needs a limiting support and prevents a driver from being crushed when sitting down. Meanwhile, the mechanical structure of the seating detection device needs to have enough resilience force, so that the driver can ensure that the sensor or the switch is released to return when the driver leaves.
The following are specific circuits of the 7 seating detection devices.
Fig. 17 shows a normally open switch seating detection device of an electric door lock. When the driver sits down, the lock-out signal is switched on, and when the driver leaves, the lock-out signal is switched off to stop the vehicle. The lock inlet wire can also be controlled, the effect is the same, but the power supply of other parts of the system is not influenced. The switch can be directly connected in series with the lock wire, and also can be connected on the wiring of a PCB (printed circuit board) of an intelligent component or a controller in the front of a vehicle. The latter requires separate external leads for the automotive front intelligence or controller. The former is preferred by the present invention because it does not involve the wiring structure of the in-vehicle intelligent components or the controller.

The switch can be directly connected in series with a power supply line or an output line, and can also be connected with a wiring of a PCB (printed circuit board) of an intelligent component or a controller in the front of a vehicle. The latter requires separate external leads for the automotive front intelligence or controller. The former is preferred by the present invention because it does not involve the wiring structure of the in-vehicle intelligent components or the controller. When the driver sits down, the accelerator is switched on and works with a normal signal, and when the driver leaves, the accelerator signal is 0, namely neutral, and the vehicle stops.
Fig. 20 shows a normally open switch seating detection device of the alarm. The switch can be connected in series on the output line of the alarm, and also can be connected on the wiring of a PCB (printed circuit board) of an intelligent component or a controller in the front of a vehicle. The latter requires separate external leads for the automotive front intelligence or controller. The former is preferred by the present invention because it does not involve the wiring structure of the in-vehicle intelligent components or the controller. When the driver sits down, the alarm is switched on and works with a normal signal, and when the driver leaves, the alarm stops working due to an abnormal signal.

The switch is connected in series on a communication line and also can be connected on a wiring line of a PCB (printed circuit board) of an intelligent component or a controller in the front of a vehicle. The latter requires separate external leads for the automotive front intelligence or controller. The former is preferred by the present invention because it does not involve the wiring structure of the in-vehicle intelligent components or the controller. When a driver sits down, the driver works with normal communication signals, and when the driver leaves, the driver stops working due to abnormal communication signals. The device is only suitable for the electric vehicle with a bus control system.
