Description

Novel speed-regulating rotating handle with function of preventing accidental speed change

Technical Field

The technology belongs to the technical field of speed control systems of motor vehicles, and mainly relates to design and manufacture of speed-regulating rotating handles of motorcycles and bicycles with power drive.

Background

The motorcycle and bicycle with power drive include the ordinary motor tricycle, ordinary two-wheeled motorcycle, light motorcycle that various energy power such as oil, electricity drive, and electric bicycle, etc., the power and speed of almost all these types of vehicles are controlled and implemented through the "speed governing rotating handle" that is installed on the right hand grip of locomotive in the rotation at present, like this, under the mode that the vehicle is in "going ahead", look from the vehicle right side, the anticlockwise rotation speed governing rotating handle can increase the vehicle power that advances and make the vehicle accelerate, the clockwise rotation speed governing rotating handle can reduce the vehicle power that advances and make the vehicle slow down. The control mode has the advantages of low cost, simplicity in control, practicality and the like, but the speed-regulating rotating handle in the current form is hidden with great potential safety hazards. For example, a driver may accidentally rotate the speed-adjusting rotating handle during getting off and parking or during the process of slowly driving a cart, so that the vehicle is suddenly accelerated to cause an accident; even if a driver rides a vehicle, the driver can accidentally rotate the speed-regulating rotating handle due to various emergencies such as bumping of the vehicle, so that the vehicle suddenly changes speed in the driving process to cause accidents; and so on. The number of motorcycles and bicycles with power drive is huge, the number of electric bicycles is reported to be as high as 2.5 hundred million in 2019, so that a large number of vehicles with certain potential safety hazards are driven on roads and are a serious problem of the whole society, and in any case, "safety" is a primary factor which must be considered by all vehicles, so that the potential safety hazard of the current speed-regulating rotating handle is an urgent problem to be solved.

To address this problem, many documents provide a number of solutions, such as patents CN103738187A, CN104385926A, CN103935247A, CN203157742U, CN203438868U, CN204263954U, CN207388880U, CN203623389U, CN202507943U, and so on. All these solutions have a common feature, that is: through adding some "discernment controlling means" to guarantee that electric bicycle's motor can be in the outage state automatically under the condition of not having the driver to ride, thereby can avoid the driver to rotate the electric bicycle suddenly that the speed governing is changeed the handle and is led to in the process of getting off the car shallow by accident. However, for most motorcycle and bicycle manufacturers, the additional addition of "identification control devices" to motorcycles and bicycles not only adds additional cost to these "identification control devices", but may also require the modification or alteration of the overall industrial production process of motorcycles and bicycles. All this causes the production costs of motorcycles and bicycles, which are not very expensive per se, to increase considerably, together with the other disadvantages and inconveniences that the added "identification control devices" may have, which directly leads to the fact that many of the solutions reported in the literature are not put into practical use. In addition, the various solutions reported in the literature do not address the situation of "sudden shift of the vehicle caused by accidental rotation of the throttle knob during the ride of the vehicle by the driver".

Disclosure of Invention

The invention mainly aims to provide a simple and practical novel speed-regulating rotating handle adopting a novel control mode, which not only has the safety function and can prevent the sudden speed change of a vehicle caused by the unexpected rotation of the speed-regulating rotating handle to a great extent so as to avoid accidents, but also can directly replace the traditional speed-regulating rotating handle to be installed and applied to various motorcycles and bicycles at present. The specific contents are as follows:

1) the inventor finds that an important root cause of potential safety hazard of the current speed-regulating rotating handle is as follows: the control mode design of current speed governing commentaries on classics handle is unreasonable, is vehicle power or speed control system based on "positive feedback" mode, in case the accident situation appears, "the speed governing commentaries on classics handle unexpected rotation appear" and "sudden speed change appears in electric bicycle" mutual cooperation between the two strengthens, finally probably leads to vehicle speed out of control, causes unpredictable occurence of failure. Therefore, in order to solve the potential safety hazard of the current speed regulating rotating handle, the invention designs a novel speed regulating rotating handle adopting a novel control mode based on a vehicle power or speed control system of a negative feedback mode, and the novel speed regulating rotating handle, a driver, a controller, a power device and a vehicle body jointly form the power or speed control system of the vehicle. The novel speed regulation rotating handle is usually arranged on a right handle bar of a head of a motorcycle or an electric bicycle, a driver holds a right speed regulation rotating handle (shown in figure 1) downwards from the upper direction of the right speed regulation rotating handle by a right hand to control the novel speed regulation rotating handle, when the vehicle is in a forward running mode, the driver watches from the right side of the vehicle, the right hand rotates the right speed regulation rotating handle clockwise to increase the forward power of the vehicle so as to accelerate the vehicle forwards, the right hand pushes the right speed regulation rotating handle forwards from the upper direction (shown in figure 1), the counterclockwise rotates the right speed regulation rotating handle to reduce the forward power of the vehicle so as to reduce the forward speed of the vehicle, and the right hand pulls the right speed regulation rotating handle backwards from the upper direction to reduce the forward speed of the vehicle (shown in figure 2), obviously, the novel control mode of the right speed regulation rotating handle conforms to the negative feedback control of the mode The 'steering direction is consistent with the speed change direction of the whole vehicle'. Of course, the novel speed-regulating rotating handle can also be designed to be arranged on the left handle bar, the left hand of the driver holds the speed-regulating rotating handle downwards from the upper part of the left speed-regulating rotating handle bar to control, when the vehicle is in a forward running mode, viewed from the left side of the vehicle, a driver rotates the left speed regulating rotating handle counterclockwise by the left hand to increase the forward power of the vehicle so as to accelerate the vehicle forward, namely the left hand pushes the left speed regulating rotating handle forward from the upper part so as to accelerate the vehicle forward, and rotates the left speed regulating rotating handle clockwise so as to reduce the forward power of the vehicle so as to decelerate the vehicle in the forward process, namely the left hand pulls the left speed regulating rotating handle backward from the upper part so as to decelerate the vehicle in the forward process, and similarly, the new control mode of the left speed regulating rotating handle also meets the requirement that the control direction of the control device is consistent with the speed change direction of the whole vehicle in a negative feedback mode.

By applying the novel speed-regulating rotating handle adopting the new control mode, if a driver accidentally rotates the right speed-regulating rotating handle clockwise in the process of getting off and stopping the vehicle or the process of slowly moving the vehicle (as shown in figure 1), the power of the power device is controlled by the controller to be suddenly increased, so that the whole vehicle body is suddenly accelerated forwards, and the driver is in a static or slow moving state at the moment and moves backwards relative to the vehicle body which is suddenly accelerated forwards, so the right hand holding the right speed-regulating rotating handle downwards from the upper direction also moves backwards, and meanwhile, the right hand pulls the right speed-regulating rotating handle backwards from the upper direction, so that the right speed-regulating rotating handle generates a negative feedback effect of anticlockwise rotation (as shown in figure 2), therefore, the operation of clockwise rotating the right speed regulating rotating handle due to accident at the beginning is weakened or even eliminated, the power of the power device is controlled by the controller, the sudden forward acceleration of the vehicle body is weakened or even eliminated, and the unpredictable accident caused by the sudden acceleration out of control of the vehicle is avoided.

By applying the novel speed-regulating rotating handle adopting the novel control mode, if a driver accidentally rotates the right speed-regulating rotating handle clockwise (as shown in figure 1) due to various emergencies such as bumping of a vehicle in the process of advancing the riding vehicle, the power of the power device is controlled by the controller to be suddenly increased, so that the whole vehicle body is suddenly accelerated forwards, and the right hand holding the right speed-regulating rotating handle from the upper direction to the lower direction moves backwards relative to the vehicle body suddenly accelerated forwards due to the inertia of the driver, and meanwhile, the right hand pulls the right speed-regulating rotating handle backwards from the upper direction, so that the right speed-regulating rotating handle generates a negative feedback effect of anticlockwise rotation (as shown in figure 2), therefore, the operation of clockwise rotating the right speed regulating rotating handle due to accident at the beginning is weakened or even eliminated, the power of the power device is controlled by the controller, the sudden forward acceleration of the vehicle body is weakened or even eliminated, and the unpredictable accident caused by the sudden acceleration out of control of the vehicle is avoided.

By applying the novel speed-regulating rotating handle adopting the novel control mode, if a driver accidentally rotates the right speed-regulating rotating handle counterclockwise (shown in figure 2) due to various emergencies such as bumping of a vehicle in the process of advancing the riding vehicle, the power of the power device is controlled by the controller to be suddenly reduced, so that the whole advancing vehicle body suddenly reduces the speed, the right hand holding the right speed-regulating rotating handle from the upper part to the lower part moves forwards relative to the suddenly reduced vehicle body due to the inertia of the driver, and meanwhile, the right hand pushes the right speed-regulating rotating handle forwards above the right hand, so that the right speed-regulating rotating handle generates a negative feedback effect of clockwise rotation (shown in figure 1), therefore, the operation of anticlockwise rotating the right speed regulating rotating handle due to accident at the beginning is weakened or even eliminated, the power of the power device is controlled by the controller, the sudden speed reduction of the vehicle body during the advancing process is weakened or even eliminated, and the unpredictable accident caused by the sudden and urgent speed reduction of the vehicle is avoided.

2) According to the novel speed regulating rotating handle adopting the novel control mode, the simple and practical novel speed regulating rotating handle with the safety function of preventing accidental speed change is designed and manufactured. The research of the inventor shows that: the control mode adopted by the speed-regulating rotating handle used by various motorcycles and bicycles at present is the traditional control mode of a vehicle power or speed control system belonging to a positive feedback mode, and the widely used traditional speed-regulating rotating handle is only suitable for the traditional control mode in structure and cannot be suitable for the new control mode provided by the invention, so that compared with the traditional speed-regulating rotating handle and the novel speed-regulating rotating handle, the structure of the novel speed-regulating rotating handle is necessarily changed and improved to be suitable for the new control mode. All the components of the speed-regulating rotating handle comprise two components, namely a component 'handle seat' fixed on a handle bar rod and another component 'rotating handle' matched with the component but capable of rotating, and the structural relationship between the two components is closely related to the control mode of the speed-regulating rotating handle. In the "conventional speed-adjusting twist grip", the structural relationship between the "grip seat" and the "twist grip" has a feature that, when the speed-adjusting twist grip is designed to be mounted on the right handlebar of the motorcycle, the "twist grip" is counterclockwise from the "reset position" to the "maximum rotation position" with respect to the "grip seat" as viewed from the right side of the vehicle; when the speed-regulating rotating handle is designed to be installed on a left handlebar of a headstock, the rotating handle is in a clockwise direction relative to a handle seat from a reset position to a maximum rotating position when viewed from the left side of a vehicle. Because the 'new control mode' and the 'traditional control mode' proposed by the invention are opposite in rotation direction, in the 'novel speed regulation rotating handle', the structural relationship between the 'handle seat' and the 'rotating handle' is also opposite to that of the 'traditional speed regulation rotating handle', namely the structural relationship between the 'handle seat' and the 'rotating handle' has the following characteristics that when the 'novel speed regulation rotating handle' is designed to be arranged on the right handle of the locomotive, the 'rotating handle' is clockwise from the 'reset position' to the 'maximum rotation position' relative to the 'handle seat' when viewed from the right side of the vehicle; when the novel speed regulation rotating handle is designed to be installed on a left handlebar of a locomotive, the rotating handle is in an anticlockwise direction relative to a handle seat from a reset position to a maximum rotating position when viewed from the left side of a vehicle. Corresponding to the opposite change of the structural relation between the handle seat and the rotating handle, the direction of the reset acting force of a part for controlling the resetting of the rotating handle in the internal structure of the novel speed regulating rotating handle is opposite to that of the traditional speed regulating rotating handle. Meanwhile, in the process that the 'rotating handle' turns to the 'maximum rotating position' from the 'reset position', in order to ensure that the 'novel speed regulating rotating handle' outputs the same speed regulating signal as the 'traditional speed regulating rotating handle', the installation direction of a part for controlling and generating the speed regulating signal in the internal structure of the 'novel speed regulating rotating handle' is also opposite to that of the 'traditional speed regulating rotating handle'. Thus, the simple and easy, practical novel speed-regulating rotating handle adopting the novel control mode can be obtained, and the novel speed-regulating rotating handle can directly replace the traditional speed-regulating rotating handle to be installed and applied to various current motorcycles and bicycles without changing devices outside the speed-regulating rotating handle. For the sake of specific explanation, the following description takes a "hall speed-adjusting handle" mounted on the right handle bar and using hall sensors, which is widely used at present (but does not represent that the method of the present invention is only applied to the speed-adjusting handle). Since the content of item 2) of the present invention is actually the specific application and implementation of the 'new speed-regulating rotating handle' adopting the 'new control mode' in the actual speed-regulating rotating handle in item 1), a specific example related to the content of the present invention can be seen in "example 1" of item 1) of the present invention. The novel speed regulating rotating handle designed by the invention adopts a novel control mode, and according to the content of the item 1), the novel speed regulating rotating handle naturally has a safety function of preventing sudden speed change of a vehicle caused by unexpected rotation of the speed regulating rotating handle in practical application. See "example 2" for an example of the practical application of the invention in the item 2) to motorcycles and bicycles.

Detailed Description

The present invention will be described in detail with reference to the following examples and drawings, which are not intended to limit the scope of the present invention, but are merely illustrative of the practice of the present invention in some cases. After reading the present invention, those skilled in the art will appreciate that various modifications and improvements can be made to the embodiments without departing from the scope of the present invention as defined by the appended claims.

Example 1

The embodiment specifically describes how "a novel speed-regulating rotating handle adopting a 'new control mode' is implemented in the speed-regulating rotating handle used by the current electric bicycle.

As shown in a schematic diagram 3, the present widely used Hall speed-adjusting rotating handle (reset position) installed on a right handlebar and using a Hall sensor (the present embodiment does not represent the speed-adjusting rotating handle of the present invention, but the present invention is directed to the speed-adjusting rotating handle), mainly comprises a "handle seat" 1 fixed on a right handlebar stem, and a "rotating handle" 2 matched with the "handle seat" but capable of rotating, wherein a "reset position limiting block" 11, a "maximum rotation position limiting block" 12 and a "torsion spring mounting hole" 13 are processed on the "handle seat" 1, and a "Hall sensor" 3 is installed on the "rotating handle" 2, a "boss" 21, an "arc body" 22 having an "arc groove" 23, and a "torsion spring mounting hole" 24 are processed on the "arc groove" 23, wherein an "arc permanent magnet" 4 is installed in the "arc groove" 23, and two ends of a "reset torsion spring" 5 are respectively fixed in the "torsion spring mounting hole" 13 and the "torsion spring mounting hole" 24 A hole 24 is arranged on the handle seat 1, so that the handle seat 2 and the rotating handle 2 are connected together. As shown in fig. 3, the "rotating handle" 2 is rotated to the "reset position" along the pointer under the action of the clockwise elastic force of the "reset torsion spring" 5, that is, the "arc-shaped body" 22 on the "rotating handle" 2 is in the limit position where it contacts with the "reset position limit block" 11 on the "handle seat" 1, at this time, the relative position between the "hall sensor" 3 and the "arc-shaped permanent magnet" 4 is also in the "reset position", and the signal voltage output by the hall sensor "3 is the minimum signal voltage. When the rotating handle 2 rotates anticlockwise under the action of external force, the relative positions of the arc-shaped permanent magnet 4 and the Hall sensor 3 are changed, and the intensity and polarity of the magnetic field sensed by the Hall sensor 3 are changed accordingly. Until the ' rotating handle ' 2 rotates anticlockwise to the ' maximum rotating position ' (as shown in fig. 4), namely the limit position of the ' boss ' 21 on the ' rotating handle ' 2 contacting with the ' maximum rotating position limiting block ' 12 on the ' handle seat ' 1, at the moment, the relative position of the ' Hall sensor ' 3 and the ' arc-shaped permanent magnet ' 4 is also in the ' maximum rotating position ', and the signal voltage output by the Hall sensor ' 3 is the maximum signal voltage. When the power supply voltage of the Hall speed regulating rotating handle is 5V, and the rotating handle 2 rotates from a reset position to a maximum rotating position anticlockwise, the relative position of the arc-shaped permanent magnet 4 and the Hall sensor 3 is changed simultaneously, namely the intensity and the polarity of the magnetic field of the external arc-shaped permanent magnet 4 induced by the Hall sensor 3 are changed, and then the voltage of the output signal of the Hall sensor 3 is continuously increased from small to large between 0V-5V, so that the controller can control the power of the motor from small to large according to the voltage of the signal of the Hall sensor 3, and the speed of the electric bicycle is changed from slow to fast.

The present operating mode of the 'Hall speed regulating rotating handle' is a traditional operating mode of a vehicle power or speed control system belonging to a 'positive feedback' mode, and the 'Hall speed regulating rotating handle' is only suitable for the traditional operating mode in structure and cannot be suitable for a 'new operating mode' provided by the invention, so that the 'novel Hall speed regulating rotating handle' is necessarily changed and improved in structure relative to the 'Hall speed regulating rotating handle' so as to be suitable for the 'new operating mode'. According to the improved mode provided by the invention, in the novel Hall speed regulating rotating handle, the structural relationship between the handle seat and the rotating handle is opposite to that of the original Hall speed regulating rotating handle, and the novel Hall speed regulating rotating handle shown in fig. 5 (reset position) and fig. 6 (maximum rotating position) is obtained. In the novel Hall speed regulation rotating handle, relative to a handle seat, the rotating direction (clockwise direction) from a reset position to a maximum rotating position of the rotating handle is opposite to the rotating direction (anticlockwise direction) of the original Hall speed regulation rotating handle, namely the reset position and the maximum rotating position of the rotating handle of the novel Hall speed regulation rotating handle are just opposite to those of the original Hall speed regulation rotating handle. Corresponding to the opposite change of the construction relationship between the handle seat and the rotating handle, the reset elastic force direction of the part (such as the reverse reset torsion spring 5' in figures 5 and 6) for controlling the reset of the rotating handle in the internal structure of the novel Hall speed regulating rotating handle is also opposite to that of the traditional speed regulating rotating handle (such as the reset torsion spring 5 in figures 3 and 4). Meanwhile, in the process of turning the 'rotating handle' from the 'reset position' to the 'maximum rotating position', in order to ensure that the 'novel Hall speed regulating rotating handle' outputs a signal voltage which changes as same as the original 'Hall speed regulating rotating handle', according to the improvement mode provided by the invention, the installation direction of a part for controlling and generating a speed regulating signal in the internal structure of the 'novel Hall speed regulating rotating handle' is also opposite to that of the original 'Hall speed regulating rotating handle' (such as the 'arc permanent magnet' 4 in figures 3 and 4), namely, the 'reverse arc permanent magnet' in figures 5 and 6, and because the installation directions of the two ends are opposite, the polarity directions of the two ends of the 'reverse arc permanent magnet' in figures 5 and 6 are also opposite to the polarity directions of the two ends of the 'arc permanent magnet' 4 in figures 3 and 4. Therefore, the novel Hall speed regulating rotating handle which adopts a novel control mode can be obtained, the novel Hall speed regulating rotating handle can directly replace the original Hall speed regulating rotating handle to be installed and applied to various current motorcycles and bicycles, and devices except the speed regulating rotating handle do not need to be changed.

Fig. 5 shows a novel hall speed-regulating rotating handle (reset position) corresponding to the hall speed-regulating rotating handle shown in fig. 3. The novel Hall speed regulation rotating handle mainly comprises components of a handle seat 1 fixed on a handle bar of a right handle and a rotating handle 2 matched with the handle seat but capable of rotating, wherein, a maximum rotation position limited block 11, a reset position limited block 12 and a torsion spring mounting hole 13 are processed on the handle seat 1, a Hall sensor 3, an arc body 22 with an arc groove 23 and a torsion spring mounting hole 24 are arranged on the rotating handle 2, wherein, a reverse arc permanent magnet 4' is arranged in the arc groove 23, a reverse reset torsion spring 5' is connected between the handle seat 1 and the rotating handle 2, and two ends of the reverse reset torsion spring 5' are respectively fixed in the torsion spring mounting hole 13 and on the torsion spring mounting hole 24; however, the polarity of the 'reverse arc-shaped permanent magnet' 4 'is opposite to that of the' arc-shaped permanent magnet '4' of the original 'Hall speed regulating rotating handle', so that the signal voltage generated by the interaction of the 'reverse arc-shaped permanent magnet' 4 'and the' Hall sensor '3 is opposite to the change direction of the signal voltage generated by the interaction of the' arc-shaped permanent magnet '4' and the 'Hall sensor' 3, and meanwhile, the direction of the 'reverse reset torsion spring' 5 'is opposite to that of the' reset torsion spring '5 of the original' Hall speed regulating rotating handle ', so that the rotating direction of the' rotating handle '2 is opposite to that of the original' Hall speed regulating rotating handle ', and correspondingly, the' reset position 'and the' maximum rotating position 'of the' rotating handle '2 are also exactly opposite to that of the original' Hall; in addition, the maximum rotation position limiting block 11 of the novel Hall speed regulating rotating handle is actually the reset position limiting block 11 of the original Hall speed regulating rotating handle, only different names are obtained due to different functions of different types of speed regulating rotating handles, and similarly, the reset position limiting block 12 of the novel Hall speed regulating rotating handle is actually the maximum rotation position limiting block 12 of the original Hall speed regulating rotating handle. The novel ' speed regulation rotating handle ' is arranged on a right handle bar, as shown in figure 5, the ' rotating handle ' 2 rotates anticlockwise to a ' reset position ' under the action of the anticlockwise elasticity of a ' reverse reset torsion spring ' 5', namely, the limit position of the ' rotating handle ' 2, at which the ' boss ' 21 is contacted with the ' reset position limiting block ' 12 on the ' handle seat ' 1, is equivalent to the ' maximum rotating position ' of the ' rotating handle ' 2 of the original ' Hall speed regulation rotating handle ' shown in figure 4, however, because the ' reverse arc permanent magnet ' 4' is opposite in polarity to the ' arc permanent magnet ' 4' of the original ' Hall speed regulation rotating handle ', the relative position of the ' Hall sensor ' 3 and the ' reverse arc permanent magnet ' 4' is still the same as the ' reset position ' of the original ' Hall speed regulation rotating handle ' shown in figure 3, the signal voltage output by the Hall sensor ' 3 is also the same as that of the original ' Hall speed regulation rotating handle ' shown in figure 3, is the minimum signal voltage. When the rotating handle 2 rotates clockwise under the action of external force, the relative positions of the reverse arc-shaped permanent magnet 4' and the Hall sensor 3 are changed, and the strength and polarity of the magnetic field sensed by the Hall sensor 3 are changed accordingly. Until the ' rotating handle ' 2 rotates clockwise to the ' maximum rotating position ' (as shown in a schematic diagram 6), namely the limit position of the ' arc-shaped body ' 22 on the ' rotating handle ' 2 contacting with the ' maximum rotating position limiting block ' 11 on the ' handle seat ' 1 is equivalent to the ' reset position ' of the ' rotating handle ' 2 of the original ' hall speed regulating rotating handle ' shown in fig. 3, however, because the polarity of the ' reverse arc-shaped permanent magnet ' 4' is opposite to that of the ' arc-shaped permanent magnet ' 4 of the original ' hall speed regulating rotating handle ', the relative position of the ' hall sensor ' 3 and the ' reverse arc-shaped permanent magnet ' 4' is still the same as that of the ' maximum rotating position ' of the original ' hall speed regulating rotating handle ' shown in fig. 4, and the signal voltage output by the hall sensor ' 3 is also the same as that of the original ' hall speed regulating rotating handle ' shown in fig. 4 and. Therefore, when the novel Hall speed regulation rotating handle is installed on a right handle of a head of the electric bicycle, the right hand of a driver holds the speed regulation rotating handle downwards from the upper direction of the novel Hall speed regulation rotating handle to control, when the electric bicycle is in a forward running mode, the right hand of the driver rotates the rotating handle clockwise from a reset position to a maximum rotating position, the output signal voltage of the Hall sensor 3 is continuously increased from small to large from 0V to 5V, the controller can control the power of the power device from small to large according to the signal voltage of the Hall sensor 3, and the speed of a bicycle body of the electric bicycle is changed from slow to fast; the ' right hand ' rotates anticlockwise ' rotating handle ' 2 from a ' maximum rotating position ' to a ' reset position ', the voltage of an output signal of the Hall sensor ' 3 continuously and linearly changes from large to small between 5V-0V, and the ' controller ' can control the power of the ' power device ' from large to small according to the voltage of the signal of the ' Hall sensor ' 3, so that the ' body ' speed of the electric bicycle is changed from fast to slow. This "novel hall speed governing is changeed handle" manufacturing cost changes almost completely unanimously with traditional speed governing, also need not change other connecting devices (for example controller) of electric bicycle in the installation is used, can directly replace "traditional speed governing to change the handle" installation and be applied to various motorcycles and bicycles at present, and simultaneously, this "novel hall speed governing is changeed handle" is the speed governing that adopts "newly controlling the mode".

Example 2

The embodiment specifically describes how "a simple and practical 'novel speed-regulating rotating handle' with 'preventing accidental speed change' safety function is implemented in the electric bicycle.

The novel Hall speed regulation rotating handle shown in fig. 5 is arranged on a right handle of the electric bicycle, and a right hand of a driver holds the right speed regulation rotating handle from top to bottom (shown in fig. 1 and 2). The control system of the whole electric bicycle mainly comprises a driver, a novel Hall speed regulation rotating handle, a controller, a power supply and a motor and a bicycle body.

If a driver turns the rotating handle 2 of the novel Hall speed-regulating rotating handle clockwise accidentally (in the same direction as the direction of the reset position shown in FIG. 5 to the maximum turning position shown in FIG. 6) in the process of getting off or stopping or slowly moving the cart, the relative positions of the reverse arc-shaped permanent magnet 4' and the Hall sensor 3 are changed, the intensity and the polarity of the magnetic field sensed by the Hall sensor 3 are changed, the voltage of the output signal of the Hall sensor 3 is increased suddenly, and the controller can control the power of the power supply and the motor to be increased suddenly according to the voltage of the signal of the Hall sensor 3, so that the whole vehicle body is accelerated forwards suddenly. Because the 'driver' is in a static or slow-moving state at this time and moves backwards relative to the 'vehicle body' which is suddenly accelerated forwards, the 'right hand' holding the 'novel Hall speed regulation rotating handle' downwards from the upper direction also moves backwards along with the 'right hand', and meanwhile, the 'right hand' produces a backward pulling action on the 'novel Hall speed regulation rotating handle' from the upper part, so that the 'rotating handle' 2 of the 'novel Hall speed regulation rotating handle' produces a negative feedback 'effect of anticlockwise rotation, and the operation of the' novel Hall speed regulation rotating handle 'caused by the fact that the' right hand 'accidentally rotates clockwise' is weakened or even eliminated. Therefore, the relative position of the reverse arc-shaped permanent magnet 4 and the Hall sensor 3 is reversely changed and even restored to the original position, the intensity and the polarity of the magnetic field sensed by the Hall sensor 3 are reversely changed, and the voltage of the output signal of the Hall sensor 3 is reduced and even restored to the original value. The controller can control the power of the power supply and the motor to weaken suddenly increased power according to the signal voltage of the Hall sensor 3, and even recover the original power, so that the sudden acceleration of the vehicle body is weakened or even eliminated, and unpredictable accidents caused by the sudden acceleration out of control of the electric bicycle are avoided.

If the ' driver ' accidentally rotates the ' rotating handle ' 2 of the ' novel Hall speed regulating rotating handle ' clockwise (in the same direction as the direction from the ' reset position ' shown in figure 5 to the ' maximum rotating position ' shown in figure 6) due to various emergencies such as bumping of the vehicle and the like in the process of advancing of the riding vehicle, the relative position of the ' reverse arc-shaped permanent magnet ' 4' and the ' Hall sensor ' 3 is changed, the magnetic field intensity and the polarity sensed by the ' Hall sensor ' 3 are changed accordingly, the output signal voltage of the ' Hall sensor ' 3 is suddenly increased, and the controller can control the power of the ' power supply and the motor ' to be suddenly increased according to the signal voltage of the ' Hall sensor ' 3, so that the whole ' vehicle body ' is suddenly accelerated forwards. Because the inertia of the driver moves backwards relative to the vehicle body which accelerates suddenly and forwards, the right hand holding the novel Hall speed regulating rotating handle downwards from the upper direction also moves backwards, and meanwhile, the right hand pulls the novel Hall speed regulating rotating handle backwards from the upper part, so that the rotating handle 2 generates a negative feedback effect of anticlockwise rotation, and the operation of accidentally rotating the rotating handle 2 clockwise just starting from the right hand is weakened or even eliminated. Therefore, the relative position of the reverse arc-shaped permanent magnet 4 and the Hall sensor 3 is reversely changed and even restored to the original position, the intensity and the polarity of the magnetic field sensed by the Hall sensor 3 are reversely changed, and the voltage of the output signal of the Hall sensor 3 is reduced and even restored to the original value. The controller can control the power of the power supply and the motor according to the signal voltage of the Hall sensor 3 to reduce the suddenly increased power and even recover the original power, so that the sudden acceleration of the vehicle body is weakened or even eliminated, and unpredictable accidents caused by the sudden acceleration out of control of the electric bicycle are avoided.

If the ' driver ' accidentally rotates the ' rotating handle ' 2 of the ' novel Hall speed regulating rotating handle ' counterclockwise due to various emergencies such as bumping of the vehicle and the like in the process of advancing of the riding vehicle (the direction is the same as the direction of the ' maximum rotating position ' shown in figure 6 to the ' reset position ' shown in figure 5), the relative position of the ' reverse arc-shaped permanent magnet ' 4' and the ' Hall sensor ' 3 is changed, the magnetic field intensity and the polarity sensed by the ' Hall sensor ' 3 are changed accordingly, the output signal voltage of the ' Hall sensor ' 3 is suddenly reduced, and the controller can control the power of the ' power supply and the motor ' to be suddenly reduced according to the signal voltage of the ' Hall sensor ' 3, so that the whole advancing ' vehicle body ' is suddenly decelerated. Because the inertia of the driver moves forward relative to the vehicle body which suddenly reduces the speed and moves forward, the right hand holding the novel Hall speed regulating rotating handle from the upper direction moves forward, and meanwhile, the right hand pushes the novel Hall speed regulating rotating handle forwards from the upper part, so that the rotating handle 2 generates a negative feedback effect of anticlockwise rotation, and the operation of accidentally anticlockwise rotating the rotating handle 2 by the right hand which is just started is weakened or even eliminated. Therefore, the relative position of the reverse arc-shaped permanent magnet 4 and the Hall sensor 3 is reversely changed and even restored to the original position, the intensity and the polarity of the magnetic field sensed by the Hall sensor 3 are reversely changed, and the voltage of the output signal of the Hall sensor 3 is increased and even restored to the original value. The controller can control the power of the power supply and the motor to increase the suddenly reduced power according to the signal voltage of the Hall sensor 3, and even restore the original power, so that the sudden deceleration of the advancing vehicle body is weakened or even eliminated, and unpredictable accidents caused by the sudden emergency deceleration of the electric bicycle are avoided.

In summary, the above is a specific embodiment of how the "new hall speed-regulating rotating handle" shown in fig. 5 and fig. 6 can realize the "prevent the vehicle from suddenly changing speed due to the unexpected rotation of the speed-regulating rotating handle" safety function in the control system of the electric bicycle.
