[0005] The invention discloses a handlebar-type driving operation control device for an electric vehicle. When the electric vehicle is to be controlled to move forward, the driver holds the handle of the handlebar-type driving lever and pushes it forward, and the handle drives the connecting rod and the rotating disk to rotate forward. The rotating disk rotates forward around the shaft holes of the left and right connecting seats through the rotating shafts on both sides, and the rotating disk drives the forward magnetic steel on the front outer wall to rotate. The forward magnetic steel gradually approaches and senses the forward linear Hall element (the forward linear Hall element is a switch-type position sensor). The magnetic field detected by the forward linear Hall element is converted into an electromotive force output. The switch-type position sensor converts the measured data, such as current, voltage, torque, etc., into electrical signals. These electrical signals are adjusted to appropriate values ​​by a digital controller in the connection circuit, and then input into a power converter. The power converter adjusts the energy flow between the power battery and the motor according to the data to control the hub electric The speed of the motor increases as the sensing area of ​​the forward magnetic steel and the forward linear Hall element gradually increases, and the magnetic field strength changes accordingly. The electrical signal data of the switch type position sensor is then input into the power converter. The power converter inputs the power of the power battery into the stator armature of the hub motor according to the electrical signal data. As the handle is gradually pushed forward, the output voltage of the power battery increases accordingly. Then, the voltage of the stator armature of the hub motor increases. When the voltage of the armature increases, the motor torque will increase, thereby increasing the speed of the hub motor. Conversely, when the motor armature voltage decreases, the armature current and the hub motor torque will decrease, thereby causing the hub motor speed to decrease. In this way, the hub motor rotor rotates, and the electric wheel that integrates the hub motor and the wheel is directly driven forward to rotate, so that the electric car moves forward. The driver can control the forward driving speed of the electric car according to the road conditions and the size of the forward rotation angle of the handle.When the electric car is to be controlled to reverse, the driver pushes the handle of the handle-type steering lever backward, the handle drives the connecting rod and the rotating disk to rotate backward, the rotating disk drives the reverse magnet on the front outer wall to rotate, the reverse magnet gradually approaches and senses the reverse linear Hall element (the reverse linear Hall element is a switch-type position sensor), and the magnetic field detected by the reverse linear Hall element is converted into an electromotive force output. The switch-type position sensor converts the measured data, such as current, voltage, torque, etc., into electrical signals, which are adjusted to appropriate values ​​by the digital controller in the connection circuit, and then input into the power converter. The power converter controls the speed of the hub motor by adjusting the energy flow between the power battery and the motor based on data. As the inductive area of ​​the backward magnetic steel and the backward linear Hall element gradually increases, the magnetic field strength changes accordingly, and the electrical signal data of the switch position sensor is input into the power converter. The power converter inputs the power of the power battery into the stator armature of the hub motor according to the electrical signal data. As the handle is gradually pushed backward, the output voltage of the power battery increases accordingly. Then, the voltage of the stator armature of the hub motor increases. When the voltage of the armature increases, the motor torque will increase, thereby increasing the speed of the hub motor, and vice versa. When the motor armature voltage decreases, the armature current and the wheel hub motor torque will decrease, thereby causing the wheel hub motor speed to decrease. When the rotating disk rotates backward, the protruding arc ribs on the outer wall of the rear side of the rotating disk rotate accordingly, and the arc ribs contact the small roller backward. The protruding arc ribs drive the small roller to rotate downward, and the small roller drives one end of the swing rod to rotate downward, while the other end of the swing rod drives the lower contact upward and closes with the upper contact, so that the reverse rotation power supply of the electric wheel hub motor is turned on. In this way, the wheel hub motor rotor rotates in the opposite direction, and the electric wheel that integrates the wheel hub motor and the wheel is directly driven to rotate in the opposite direction and backward, so that the electric car can reverse. The driver can control the speed of the electric vehicle by rotating the handle backward according to the reversing road conditions or parking position; when the handle is pushed forward or backward, after people release the handle, the torsion spring between the left and / or right outer walls of the rotating disk and the connecting seat drives the rotating disk to return to its original position under the action of the restoring force, and drives the lower contact to be disconnected from the upper contact under the tension of the tension spring. In addition, when the driver pushes the handle forward or backward, the torsion spring can play a torsion locking role, which can prevent the driver from pushing the handle forward or backward and offside, and plays a role of limit insurance to ensure the safety of the electric vehicle.When the electric vehicle is to be controlled to turn left, the driver holds the handle of the handle-type steering column and rotates it to the left along the axis of the rotating rod. The rotating rod drives the left magnetic steel on the outer wall to rotate. The left magnetic steel gradually approaches and senses the left-turn linear Hall element (the left-turn linear Hall element is a switch-type position sensor) on the inner wall of the convex ring. The magnetic field detected by the left-turn linear Hall element is converted into an electromotive force output. The switch-type position sensor converts the measured data, such as current, voltage, torque, etc., into electrical signals. These electrical signals are adjusted to appropriate values ​​by connecting the digital controller in the circuit, and then input into the power converter. The power converter uses the data to control the energy flow to the power battery and the motor. The speed of the hub motor is controlled by adjusting between the left magnetic steel and the left-turn linear Hall element. As the induction area of ​​the left magnetic steel and the left-turn linear Hall element gradually increases, the magnetic field strength changes accordingly, and the electrical signal data of the switch position sensor is input into the power converter. The power converter inputs the power of the power battery into the stator armature of the hub motor according to the electrical signal data. As the handle gradually rotates axially to the left, the output voltage of the power battery increases accordingly. Then, the voltage of the stator armature of the hub motor increases. When the voltage of the armature increases, the motor torque will increase, thereby increasing the speed of the hub motor. Conversely, when the motor armature voltage decreases, the armature current and the torque of the hub motor will decrease, thereby causing the hub motor to rotate. The speed is reduced, and when the rotating rod rotates to the left, the rotating rod drives the left-turn switch slot on the outer wall to rotate and match the position of the left-turn top rod. When the left-turn top rod corresponds to the left-turn switch slot, the left-turn spring piece pushes the left-turn top rod to insert into the left-turn switch slot under the action of elastic force. At the same time, the left-turn top rod drives the outer contact of the left-turn power switch to move leftward and closes the inner contact of the left-turn power switch, connecting the power supply of the electric wheel motor on the right side of the vehicle. Then, the power supply of the power battery of the hub motor of the electric wheel on the left side of the vehicle (including four-wheel drive electric vehicles) is turned off, so that the left hub motor no longer drives the left electric wheel to work, the left electric wheel moves under inertia, and the right electric wheel is directly driven to rotate, causing the electric vehicle to turn. When turning left, the driver can control the speed of the electric vehicle by rotating the handle according to the direct vision of the left turning road conditions. Similarly, when the electric vehicle is to be controlled to turn right, the driver only needs to hold the handle of the handle-type steering rod and rotate it to the right along the axis of the rotating rod. The working principle is the same as that of the left rotation. When the handle is rotated to the left or right, after people release the handle, the rotating rod at the lower end of the handle drives the reset steel ball to roll along the circular arc reset inclined groove of the rotating rod under the elastic force of the reset spring. The circular arc reset inclined groove is shallow on both sides and deep in the middle. Under the thrust of the reset steel ball, the rotating rod is forced to return to its original position.When an electric vehicle needs to stop or brake in an emergency, the driver holds the handle and presses the electromagnetic brake button with his finger (3 to 5 seconds) to transmit the braking signal to the electronic control unit. The electronic control unit calculates the optimal braking force based on the wheel speed sensor signal and outputs it to the independent electromagnetic brake blocks on the four wheels. After receiving the braking force signal, the electromagnetic brake block provides it to the electronic control unit through the communication network. The electronic control unit effectively controls the braking distance based on information such as vehicle speed and vehicle mass, and feeds back to the power battery to provide equivalent control power to the electromagnetic brake block. At the same time, the power supply to the wheel hub motor is turned off to complete the necessary braking torque response. Then the electromagnetic brake block performs electromagnetic force control braking on the brake disc, ensuring that the electromagnetic brake block achieves braking. Since the wire control brake system can independently control the braking force of each wheel, the optimal adhesion can be obtained, effectively preventing the implementation of anti-lock braking. In addition, people can press the left turn indicator button on the handle to control the left turn indicator to light up and flash through the wire, press the right turn indicator button to control the right turn indicator to light up and flash through the wire, and press the horn button to control the horn to sound through the wire. The electric vehicle handle type driving operation control device of this scheme is driven by an electric motor because the electric vehicle does not have a traditional internal combustion engine. The driving wheel (referred to as the electric wheel) that integrates the wheel hub motor and the wheel can realize independent driving of the wheels of the electric vehicle, and the handle type electric vehicle driving lever is pushed forward, backward or rotated to the right or left by hand, which can realize the forward, acceleration, reverse and right and left steering of the electric vehicle; the handle type electric vehicle driving lever uses wires (cables) to connect the electric wheel, so that the driving unit controlled by the wire and the actuator (electric wheel) are connected by wires (cables), replacing the mechanical connection device of the existing technology, realizing the transformation of the traditional hard connection form of the electric vehicle into Soft connection: Since the power control is changed from hard connection to soft connection, the handle type electric car steering rod can be directly operated, and the stepless speed change from zero to the highest speed of each electric wheel and the differential requirements between each electric wheel can be realized through the wire control technology, so that the clutch, transmission, drive shaft and mechanical differential required by the traditional structure can be omitted, so that the drive system and the whole vehicle structure are simplified, the effective available space is increased, the weight of the whole vehicle is reduced, the transmission chain is shortened, the transmission efficiency is improved, and the driving range of the electric vehicle can be effectively improved. Moreover, each electric wheel can be controlled separately, and the vehicle can be simply designed as two-wheel or four-wheel drive, which can easily realize the separate adjustment of the wheel driving force and the application of yaw force control;It is easy to realize traction control system, anti-lock braking system and dynamic control system with better performance and lower cost, and it is easy to realize the electrification and activeness of electric vehicle chassis, which greatly improves the driving performance and driving performance of the vehicle. The handle-type electric vehicle steering rod has changed the traditional driving mode and mechanical mechanism of the vehicle, so that there are no pedals such as acceleration, clutch, brake, etc. in the driving room of the vehicle body, and there is no steering wheel. The interior space of the vehicle body is spacious, and the front seat space is large. The comfort of the driver and passengers is greatly improved, and it is very convenient to enter and exit the car. The driver can easily operate the ergonomically designed steering rod, which greatly improves the driving fatigue and ensures the reliability and safety of the vehicle. ;

[0006] The electric vehicle handle type driving operation control device of the present invention has a middle positioning groove in the middle of the arc reset inclined groove, and the middle positioning groove cooperates with the reset steel ball. When the rotating rod returns to its original position, the middle positioning groove of the arc reset inclined groove in the rotating rod cooperates with the reset steel ball, so that the positioning is accurate after reset.

[0007] The outer walls of the base and the connecting rod are provided with dust covers, so as to prevent dust and other impurities from entering the interior.

[0008] The upper part of the handle is provided with a grip portion protruding forward, and the lower end of the grip portion and the corner of the handle are in an arc transition. The left turn indicator button and the right turn indicator button are located at the upper end of the grip portion, the electromagnetic brake button is located at one side of the grip portion, and the horn button is located below the grip portion.

The electromagnetic brake blocks and the wheel speed sensors are respectively connected to the electronic control unit 111, and the electronic control unit is connected to the power battery 106 and the electromagnetic brake button 78. During driving operation, when the electric vehicle is to be controlled to move forward, the driver holds the handle 7 of the handle-type steering rod 101 and pushes it forward, and the handle 7 drives the connecting rod 5 and the rotating disk 41 to rotate forward, and the rotating disk 41 rotates forward around the shaft holes of the left and right connecting seats 4 through the rotating shafts 42 on both sides, and the rotating disk 41 drives the forward magnetic steel 44 on the front outer wall to rotate, and the forward magnetic steel 44 gradually approaches and senses the forward linear Hall element 21 (the forward linear Hall element is the switch type position sensor 102), and the magnetic field detected by the forward linear Hall element 21 is converted into an electromotive force output, and the switch type position sensor 102 converts the measured data, such as current, voltage, torque, etc. into electrical signals, and adjusts these electrical signals to appropriate values ​​through the digital controller 103 in the connection circuit, and then inputs them into the power converter 105. The power converter adjusts the energy flow between the power battery and the motor according to the data to control the speed of the hub motor 104. As the induction area of ​​the forward magnetic steel 44 and the forward linear Hall element gradually increases, the magnetic field strength changes accordingly, and the switch type position The electrical signal data of the sensor 102 is then input into the power converter 105. The power converter inputs the power of the power battery 106 into the stator armature of the hub motor 104 according to the electrical signal data. As the handle 7 is gradually pushed forward, the output voltage of the power battery 106 increases. Then, the voltage of the stator armature of the hub motor 104 increases. When the voltage of the armature increases, the motor torque increases, thereby increasing the speed of the hub motor 104. Conversely, when the motor armature voltage decreases, the armature current and the hub motor torque decrease, thereby causing The rotation speed of the wheel hub motor is reduced, so that the rotor of the wheel hub motor 104 rotates, and the electric wheel integrated with the wheel hub motor and the wheel 107 is directly driven to rotate forward, so that the electric car moves forward. The driver can control the forward driving speed of the electric car according to the road conditions by rotating the handle 7 forward. When the electric car is to be reversed, the driver pushes the handle 7 of the handle-type steering rod 101 backward, and the handle 7 drives the connecting rod 5 and the rotating disk 41 to rotate backward, and the rotating disk 41 drives the backward magnetic steel 45 of the front outer wall to rotate.The backward magnetic steel 45 gradually approaches and senses the backward linear Hall element 22 (the backward linear Hall element is the switch type position sensor 102). The magnetic field detected by the backward linear Hall element 22 is converted into an electromotive force output. The switch type position sensor 102 converts the measured data, such as current, voltage, torque, etc., into electrical signals, which are adjusted to appropriate values ​​by the digital controller 103 in the connection circuit, and then input into the power converter 105. The power converter adjusts the energy flow between the power battery and the motor according to the data to control the speed of the hub motor 104. As the induction area of ​​the backward magnetic steel 45 and the backward linear Hall element gradually increases, the magnetic field strength changes accordingly, and the electrical The signal data is then input into the power converter 105, and the power converter inputs the power of the power battery 106 into the stator armature of the hub motor 104 according to the electrical signal data. As the handle 7 is gradually pushed backward, the output voltage of the power battery 106 increases accordingly, and then the voltage of the stator armature of the hub motor 104 increases. When the voltage of the armature increases, the motor torque will increase, thereby increasing the speed of the hub motor 104. Conversely, when the motor armature voltage decreases, the armature current and the hub motor torque will decrease, thereby causing the hub motor speed to decrease. When the rotating disk 41 rotates backward, the protruding arc ribs 46 on the outer wall of the rear side of the rotating disk rotate accordingly, and the arc ribs contact the small roller 32 backward, and the protruding arc ribs drive the small roller to rotate downward, and the small roller drives the rocker arm One end of the swing rod 31 rotates downward, and the other end of the swing rod 31 drives the lower contact 33 upward to close with the upper contact 35, so that the reverse rotation power supply of the electric wheel hub motor 104 is turned on. In this way, the rotor of the hub motor 104 rotates in the opposite direction, and the electric wheel integrated with the hub motor and the wheel 107 is directly driven to rotate in the opposite direction backward, so that the electric car can reverse. The driver can control the speed of the electric car by rotating the handle 7 backward according to the reversing road conditions or parking position; when the handle is pushed forward or backward, after people release the handle, the torsion spring 43 between the left and / or right outer walls of the rotating disk 41 and the connecting seat 4 drives the rotating disk 41 to return to its original position under the action of the restoring force, and drives the lower contact 35 under the tension of the tension spring 34. The upper contact is disconnected. In addition, when the driver pushes the handle 7 forward or backward, the torsion spring 43 can play a torsion locking role, which can prevent the driver from pushing the handle 7 forward or backward and play a limit insurance role to ensure the safety of the electric vehicle. When the electric vehicle is to be controlled to turn left, the driver holds the handle 7 of the handle-type steering column 101 and rotates the rotating rod 70 axially to the left. The rotating rod 70 drives the left magnetic steel 74 on the outer wall to rotate. The left magnetic steel 74 gradually approaches and senses the left-turn linear Hall element 52 (the left-turn linear Hall element is a switch-type position sensor 102) on the inner wall of the convex ring 51. The magnetic field detected by the left-turn linear Hall element 52 is converted into an electromotive force output, and the switch-type position sensor 102 measures the data.For example, current, voltage, torque, etc. are converted into electrical signals, and these electrical signals are adjusted to appropriate values ​​by connecting the digital controller 103 in the circuit, and then input into the power converter 105. The power converter adjusts the energy flow between the power battery and the motor through the data to control the rotation speed of the hub motor 104. As the induction area of ​​the left magnetic steel 74 and the left-turn linear Hall element 52 gradually increases, the magnetic field strength changes accordingly, and the electrical signal data of the switch position sensor 102 is input into the power converter 105 accordingly. The power converter inputs the power of the power battery 106 into the stator armature of the hub motor 104 according to the electrical signal data. As the handle 7 gradually rotates axially to the left, the output voltage of the power battery 106 increases accordingly. Then, The voltage of the stator armature of the hub motor 104 increases. When the voltage of the armature increases, the motor torque will increase, thereby increasing the speed of the hub motor 104. Conversely, when the motor armature voltage decreases, the armature current and the hub motor torque will decrease, thereby causing the hub motor speed to decrease. When the rotating rod rotates to the left, the rotating rod drives the left-turn switch slot 72 on the outer wall to rotate to the position of the left-turn top rod 62. When the left-turn top rod corresponds to the left-turn switch slot, the left-turn spring piece 61 pushes the left-turn top rod 62 to insert into the left-turn switch slot 72 under the action of elastic force. At the same time, the left-turn top rod drives the outer contact 63 of the left-turn power switch to move to the left and close with the inner contact 60 of the left-turn power switch, turning on the power supply of the electric wheel motor on the right side of the vehicle. Then, the left side of the vehicle is turned on. The power battery power of the wheel hub motor of the electric wheel on the left (including four-wheel drive electric vehicles) is turned off, so that the left wheel hub motor no longer drives the left electric wheel to work, the left electric wheel moves under inertia, and the right electric wheel is directly driven to rotate, so that the electric vehicle turns left and realizes wire-controlled steering. The driver controls the speed of the electric vehicle turning left by rotating the handle according to the direct vision of the left-turning road conditions; similarly, when the electric vehicle is to be controlled to turn right, the driver only needs to hold the handle 7 of the handle-type steering column 101 and rotate the rotating rod 70 axially to the right, and its working principle is the same as that of left rotation; when the handle 7 is rotating to the left or right, after people release the handle, the rotating rod at the lower end of the handle 7 Under the elastic force of the reset spring 66, the reset steel ball 67 is driven to roll along the circular arc reset inclined groove 73 of the rotating rod 70. The two sides of the circular arc reset inclined groove are shallow and the middle is deep. Under the thrust of the reset steel ball 67, the rotating rod 70 is forced to return to its original position. When the electric vehicle needs to stop or brake in an emergency, the driver holds the handle 7 and presses the electromagnetic brake button 78 with his finger (3 to 5 seconds) to transmit the braking signal to the electronic control unit 111. The electronic control unit 111 calculates the optimal braking force according to the signal of the wheel speed sensor 110 and outputs it to the independent electromagnetic brake blocks 109 on the four wheels. After receiving the braking force signal, the electromagnetic brake block 109 provides it to the electronic control unit 111 through the communication network.The electronic control unit effectively controls the braking distance according to information such as vehicle speed and vehicle mass, and feeds back to the power battery 106 to provide equivalent control power to the electromagnetic brake block 109. At the same time, the power supply of the hub motor 104 is turned off to enable it to complete the necessary braking torque response. Then the electromagnetic brake block 109 performs electromagnetic force control braking on the brake disc 108, ensuring that the electromagnetic brake block 109 achieves braking; since the wire control braking system can independently control the braking force of each wheel 107, the best adhesion can be obtained, effectively preventing the implementation of anti-lock braking; in addition, people can press the left turn indicator button 76 on the handle to control the left turn indicator to light up and flash via the wire, press the right turn indicator button 77 to control the right turn indicator to light up and flash via the wire, and press the horn button 79 to control the horn to sound via the wire. The electric vehicle handle type driving operation control device of this scheme is driven by an electric motor because the electric vehicle does not have a traditional internal combustion engine. The driving wheel (referred to as the electric wheel) that integrates the wheel hub motor and the wheel can realize independent driving of the wheels of the electric vehicle, and the handle type electric vehicle driving lever is pushed forward, backward or rotated to the right or left by hand, so that the electric vehicle can move forward, accelerate, reverse and turn right or left. The handle type electric vehicle driving lever uses wires (cables) to connect the electric wheel, so that the driving unit controlled by the wire and the actuator (electric wheel) are connected by wires (cables), replacing the mechanical connection device of the prior art, realizing the change of the traditional hard connection form of the electric vehicle into a soft connection. Since the power control is changed from a hard connection to a soft connection, the handle type electric vehicle driving lever can be directly operated. By using the wire control technology, the stepless speed change from zero to the maximum speed of each electric wheel and the differential requirements between the electric wheels can be realized, thereby omitting the clutch, transmission, drive shaft and mechanical differential structures required by the traditional structure, simplifying the drive system and the whole vehicle structure, increasing the effective available space, reducing the weight of the whole vehicle, shortening the transmission chain, and improving the transmission efficiency, which can effectively improve the driving range of electric vehicles. Moreover, each electric wheel can be controlled individually, and the vehicle can be simply designed as two-wheel or four-wheel drive, which can easily realize the individual adjustment of the wheel driving force and the application of yaw force control; it is easy to realize better performance and lower cost traction control system, anti-lock braking system and dynamic control system, and it is easy to realize the electronic and active chassis of electric vehicles, which greatly improves the driving performance and driving performance of the vehicle. The handle type electric vehicle steering rod has changed the traditional driving mode and mechanical mechanism of the vehicle, so that there are no pedals such as acceleration, clutch, brake, etc. in the driving room of the vehicle body, and there is no steering wheel. The interior space of the vehicle body is spacious, and the front seat space is large. The comfort of the driver and passengers is greatly improved, and it is very convenient to enter and exit the car. The driver can easily operate the ergonomically designed steering rod, which greatly improves the driving fatigue and ensures the reliability and safety of the vehicle. The middle part of the arc reset inclined groove 73 is formed with a middle positioning groove 80, which cooperates with the reset steel ball 67. When the rotating rod 70 returns to its original position,The middle positioning groove 80 of the arc reset bevel groove 73 in the rotating rod cooperates with the reset steel ball 67 to accurately position it after reset. The outer wall of the base 1 and the connecting rod 5 is provided with a dust cover 81. With the dust cover 81, dust and other impurities are prevented from entering the interior. The upper part of the handle 7 is formed with a gripping portion 82 protruding forward, and the lower end of the gripping portion and the corner of the handle 7 are in an arc transition. The left turn indicator button 76 and the right turn indicator button 77 are located at the upper end of the gripping portion 82, the electromagnetic brake button 78 is located on one side of the gripping portion, and the horn button 79 is located below the gripping portion. The gripping portion 82 protruding forward is conducive to holding this position with one hand for operation, and the left and right turn indicator buttons 76 and 77 are located at the upper end of the gripping portion 82, and people can press and operate with their index finger or middle finger. The electromagnetic brake button 78 is located on one side of the gripping portion, and the horn button 79 is located below the gripping portion. People can press and operate with their thumbs, which is convenient for people to perform blind operations while driving. ,
