Technical Field

The invention belongs to the technical field of speed control systems of motor vehicles, and mainly relates to design and manufacture of a speed-regulating rotating handle of a motorcycle and a bicycle 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 invention provides a vehicle power or speed control system in a negative feedback mode established by using 'operator' inertia. The inventor has found that current control systems for vehicle power or speed do not take into account the feedback effect of changes in vehicle power or speed to its "operator". In some power or speed control system designs, the feedback effect of the change in vehicle power or speed to its "control device" is "positive feedback", that is, some operation of the "control device" causes a change in vehicle power or speed, and this "change" will enhance the operation of the "control device", which makes the vehicle in motion in an unstable equilibrium state, susceptible to external accidental factors. In order to overcome the defects of the current control system for the power or the speed of the motor vehicle, the invention provides a new control system for the power or the speed of the motor vehicle, which mainly comprises parts such as an operator, an operating device, a controller, a power device and a vehicle body, wherein the operating direction of the operating device is required to be consistent with the speed change direction of the whole vehicle, for example: the forward operation of the 'control device' means that the whole vehicle speed change direction is forward, and the backward operation of the 'control device' means that the whole vehicle speed change direction is backward. When the vehicle is in a normal forward state, the working principle of the control system is as follows: if the 'operator' accidentally operates the 'control device' forwards, the signal output by the 'control device' increases the forward power of the 'power device' through the 'controller', so that the forward speed of the 'car body' is increased suddenly (the speed change direction is forward), then the 'car body' with the suddenly increased forward speed can generate a 'negative feedback' action of backward operation on the 'control device' by utilizing the backward inertia of the 'operator', so that the accidental forward operation started by the 'control device' is weakened or even disappears to a certain extent; similarly, if the "operator" accidentally operates the "operating device" backwards, the signal output by the "operating device" will reduce the forward power of the "power device" through the "controller", so that the forward speed of the "vehicle body" is suddenly reduced (the speed change direction is backwards), then the "vehicle body" with the suddenly reduced forward speed can utilize the forward inertia of the "operator" to generate a "negative feedback" effect of the forward operation on the "operating device", so that the accidental backwards operation of the "operating device" is reduced to a certain extent or even disappears. When the vehicle is in a normal backward state, the working principle of the control system is as follows: if the 'operator' accidentally operates the 'control device' forwards, the signal output by the 'control device' reduces the backward power of the 'power device' through the 'controller', so that the backward speed of the 'car body' is suddenly reduced (the speed change direction is forwards), then the 'car body' with the suddenly reduced backward speed can generate the 'negative feedback' action of backward operation on the 'control device' by utilizing the backward inertia of the 'operator', so that the accidental forward operation of the 'control device' is weakened or even disappears to a certain extent; similarly, if the "operator" accidentally operates the "operating device" backwards, the signal output by the "operating device" will increase the backward power of the "power device" through the "controller", so that the backward speed of the "vehicle body" is suddenly increased (the speed change direction is backward), then the "vehicle body" with the suddenly increased backward speed can utilize the forward inertia of the "operator" to generate a "negative feedback" effect of the forward operation on the "operating device", so that the accidental backward operation started by the "operating device" is reduced to a certain extent or even disappears. Therefore, the vehicle power or speed control system in the negative feedback mode established by the inertia of the 'operator' can prevent the influence of the 'operator' accidentally operating the 'control device' on the normal motion state of the vehicle to a certain extent, maintain the stability of the motion state of the whole vehicle and avoid some accidents.

2) Based on the vehicle power or speed control system in the negative feedback mode, the invention designs a novel speed regulating rotating handle in a novel control mode. 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.

3) 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 traditional control mode adopted by the speed regulating rotating handle used in various motorcycles and bicycles at present is a vehicle power or speed control system belonging to a positive feedback mode, and cannot be applied to the new control mode provided by the invention. Because the new control mode provided by the invention is opposite to the traditional control mode of the current speed regulating rotating handle in the rotating direction, the simple and practical novel speed regulating rotating handle adopting the new control mode can be obtained by simultaneously changing the elastic direction of the elastic component for controlling the rotating direction and the interaction direction of the relevant components for generating the speed regulating signal in the internal structure of the current speed regulating rotating handle based on the positive feedback mode and adopting the traditional control mode. 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 3) 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 2), a specific example related to the content of the present invention can be seen in "example 2" of item 2) of the present invention. The novel speed regulating rotating handle designed by the invention adopts a novel control mode, and the novel speed regulating rotating handle has the safety function of preventing sudden speed change of a vehicle caused by unexpected rotation of the speed regulating rotating handle in practical application according to the contents of the items 1) and 2) of the invention. See "example 3" for an example of the practical application of the invention item 3) to motorcycles and bicycles.
