Description

Background

Two-wheeled vehicles such as two-wheeled electric vehicles, two-wheeled motorcycles, and the like. Compared with three-wheel and four-wheel vehicles, two-wheel vehicles have the advantages of being light, convenient, cheap and low in requirements for drivers, and therefore become preferred vehicles for many people. In order to improve the comfort of the driver, the seat of the driver of the two-wheeled vehicle is generally arranged to be wider and longer, and the design form enables the driver to actually sit more than two persons on the seat.

However, small two-wheeled vehicles of the lightweight type are generally designed according to the standard of carrying only one person (i.e. the driver), and are generally not overloaded with more than one child under the age of 12, or with more than two children or an adult. The term "overload" here means: the weight of the whole manned vehicle exceeds the design standard, so that the gravity center of the whole vehicle is unstable, and the vehicle is easy to lose control in braking and steering. On the other hand, after a battery, an oil tank and an air tank are removed, the frame of the portable small two-wheeled vehicle usually has the weight of about 35 kilograms, the load capacity is limited, and the overload can cause the overload of the frame, so that the potential safety hazard is formed.

The present specification provides a two-wheeled vehicle which may be a two-wheeled electric vehicle, a two-wheeled motorcycle.

The manned two-wheeled vehicle generally divides into two kinds of situations according to the cushion form, and the first situation is that the driver's cushion is longer broad enough to carry many people, and under this kind of situation, can not set up the rear seat alone usually, and the second situation is that driver's seat position rear sets up the rear seat alone, and under this kind of situation, driver's seat position is generally less, can't sit down two people at all. The present description provides a solution to overload only for the first situation, where overload refers to a situation where, in addition to the driver, more than two children are also carried that exceed a predetermined age or weight; alternatively, an adult may be carried in addition to the driver.

Fig. 1 shows a schematic structural diagram of a two-wheeled electric vehicle, as shown in fig. 1, the two-wheeled electric vehicle is provided with a cushion 1, a battery compartment 2 is arranged below the cushion 1, and a plurality of batteries are stored in the battery compartment to form a battery pack, so as to provide a power source for the two-wheeled electric vehicle. The two-wheeled electric vehicle includes a front wheel 31 and a rear wheel 32, wherein the rear wheel 32 is a driving wheel and the front wheel 31 is a driven wheel. A driving motor 4 is provided at the shaft portion of the rear wheel 32, and the driving motor 4 is connected to the output end of the battery pack in the battery compartment 2. A motor controller 5 is arranged below the pedal of the two-wheeled electric vehicle, and the output end of the motor controller 5 is connected with the control end of the driving motor 4 and used for controlling the rotation of the driving motor 4 and the rotation speed. The bicycle is characterized in that an accelerating component and a braking component are arranged on a handlebar 6 of the two-wheeled electric vehicle, a dashboard 7 is arranged at the head part between a left handlebar and a right handlebar and used for displaying vehicle speed, prompting information, alarm information and the like, a sound prompting device such as a loudspeaker 8 is further arranged at the head, the accelerating component, the braking component, the dashboard 7, the loudspeaker 8 and other devices are all connected with a central controller 9, and the central controller 9 can be arranged at a position close to a pedal plate on the head. The connection relationship between the above-described various devices of the two-wheeled electric vehicle may be as shown in fig. 2.

The two-wheeled vehicle provided by the specification comprises a driving device, a seat cushion, at least two sensors arranged below the seat cushion and a controller. The driving device is used for driving the two-wheeled vehicle to run, and may be, for example, the driving motor 4 in fig. 1. The sensors disposed below the seat cushion are used for sensing the pressure applied to different parts of the seat cushion, and may be, for example, the

sensors

101, 102, and 103 shown in fig. 1. The controller is connected with the output end of each sensor and used for determining the number of passengers according to the output signals of the sensors, and when the number of passengers does not meet the preset condition, the driving device is controlled to be in a locking state, namely the driving device does not work. For example, the controller may refer to the central controller 9 as shown in fig. 1.

The predetermined condition may be that the number of passengers is 1 adult, or one adult and one child, and the condition that the predetermined condition is not satisfied includes at least one of: no one is riding (e.g., a situation where the driver is not controlling the vehicle to accelerate when sitting on the seat cushion), two adults are riding, one adult and more than two children are riding.

In some embodiments, the two-wheeled vehicle further comprises a prompting device for issuing a prompt to the user for indicating that the occupant does not satisfy the predetermined condition. The controller is also used for controlling the prompting device to send out prompting information when the number of passengers does not meet the preset condition. The prompt message may include the number of detected passengers, for example, the prompt message may be a voice message, and the content may be "two-person riding, overload", "two-adult riding is detected", or the like. The prompting device can be an indicator light, a loudspeaker and the like.

The sensor is not limited to a specific sensor product, but should be understood as a detection device which can sense measured information and convert the sensed information into an electric signal or other information in a required form according to a certain rule to output.

In some embodiments, the sensor may be a pressure sensor for detecting the pressure experienced by the seat cushion above the sensor. As shown in fig. 3A, these pressure sensors may be disposed at predetermined intervals on the axis of symmetry of the seat cushion. In particular, the predetermined distance may be any value between 65-75mm, for example 70mm, then the distance between

sensors

101 and 102 may be 72mm and the distance between

sensors

102 and 103 may be 75 mm. Of course, the number of the sensors distributed on the symmetry axis of the seat cushion at intervals can also be set to be four or more, and the distance between the adjacent sensors can also be other distance values, which are not listed in the application.

The controller determines the number of passengers according to the output signals of the sensors, and comprises the following steps: and according to the position of each sensor on the seat cushion symmetry axis, the output values of each sensor are corresponding to the seat cushion symmetry axis, the number of the maximum values in the sensor output values on the seat cushion symmetry axis is determined, and the number of the maximum values with the values larger than a preset threshold value is used as the number of passengers. When the maximum value is determined, it is assumed that the two virtual sensors are respectively arranged on the outer sides of the two sensors on the upper edge of the symmetry axis of the seat cushion, and the pressure values output by the two virtual sensors are 0, that is, it is assumed that the pressure values on the outer sides of the two sensors on the upper edge of the symmetry axis of the seat cushion are 0, so that the output value of the edge sensor can be determined as the maximum value in some cases. The preset threshold is used for distinguishing whether an adult or a child sits on the seat cushion part corresponding to the maximum value point.

The maximum value point in this specification means that, on a straight line or a curved surface, a value at a certain point is larger than a value at any point around the point and closest to the point in each direction, and then the point is the maximum value point. That is, on the straight line, the value at a certain point is greater than the values at the nearest points on both sides of the point, and the point is the maximum value point.

For example, if the output values of the

sensors

101, 102, 103 shown in fig. 3A are 100N (where N is a unit of force: newton), 400N, 150N, and 0N, 100N, 400N, 150N, 0N after the pressure values outside the edge sensor are supplemented, the output value of the sensor 102 is a maximum value, and only this maximum value is present, the number of occupants can be determined to be 1; if the output values of the

sensors

101, 102, 103 are 450N, 150N, 400N, and 0N, 450N, 150N, 400N, 0N after the pressure values outside the edge sensors are supplemented, the output values of the

sensors

101, 103 are maximum values, and there are 2 maximum values, it is possible to determine that the number of passengers is 2; if the output values of the

sensors

101, 102, 103 are 150N, 100N, 450N, and 0N, 150N, 100N, 450N, 0N after the pressure values outside the edge sensors are supplemented, the output values of the

sensors

101, 103 are maximum, but the output value of the sensor 101 is too small, which may correspond to a child sitting in position, and thus it can be determined that the number of occupants is 2, specifically, an adult and a child, without being overloaded.

In some embodiments, the pressure sensors may also be distributed in a curved surface. The plane is a special curved surface, so, taking the case of a plane as an example, a plane plate body is arranged below the seat cushion, a plurality of pressure sensors are arranged on the plate body, for example, the plurality of pressure sensors can be distributed symmetrically along the symmetry axis as shown in fig. 3B, and one round dot in the figure represents one sensor. Accordingly, the controller determines the number of occupants based on the output signals of the plurality of sensors, including: and (3) corresponding the output values of the sensors to the plane plate body according to the positions of the sensors on the plane plate body, determining the number of the maximum values in the output values of the sensors on the plane plate body, determining the number of the maximum values on one side of the symmetry axis of the cushion, and taking the number of the maximum values with the values larger than a preset threshold value as the number of passengers. The preset threshold is used for distinguishing whether an adult or a child sits on the seat cushion position corresponding to the maximum point.

Because the pressure sensors are distributed in a curved surface, when the maximum value is determined, a determination method of the maximum point on the curved surface is adopted. It should be noted that, in determining the maximum value, it is assumed that the pressure value outside each sensor at the position of the upper edge of the curved surface formed by the sensors is 0.

In some embodiments, the outputs of the plurality of sensors may be directly connected to the inputs of a controller (i.e., the central controller in fig. 1), and the output signals of the plurality of sensors are directly processed by the controller. In some embodiments, a signal collector, for example, the signal collector 11 shown in fig. 1, may be further provided, where output ends of the multiple sensors are connected to an input end of the signal collector 11, and an output end of the signal collector 11 is connected to an input end of the controller, that is, output signals of the multiple sensors are preprocessed by the signal collector and then sent to the controller, so as to reduce data processing amount of the controller.

In some embodiments, the sensor may be a first sensor that outputs a switching signal.

For example, the first sensor may be configured as shown in fig. 4A and 4B, that is, the first sensor includes a bottom plate 41, a key 42, and an elastic member 43. The base plate 41 is provided with a first conductor 411 and a second conductor 412, the first conductor 411 and the second conductor 412 are disconnected from each other, the first conductor 411 is connected to a power source, and the second conductor 412 serves as an output terminal of the first sensor.

The third conductor 421 is provided on the side of the key 42 facing the bottom plate 41, and the other part of the key 42 may be made of a non-conductive material. When the pressure on the seat cushion above the key 42 reaches a predetermined pressure value, the key 42 is pressed down to make the third conductor 421 contact with the first conductor 411 and the second conductor 412 and form a current path.

An elastic member 43 is provided on the base plate 41 for bouncing up the key 42. For example, the elastic member 43 may be an elastic sheet disposed on the bottom plate 41 and located between the first conductor 411 and the second conductor 412; alternatively, the elastic member 43 may be a spring having one end fixed to the base plate 41 and the other end fixed to the key 42. Of course, other modified embodiments may be adopted, and the description is not repeated.

The power supply terminal may be a high-level power supply such as +5V, or a low-level power supply such as-5V or 0V (i.e., ground), and may be provided as the case may be. It can be seen that the sensor shown in fig. 4A and 4B is capable of outputting a digital signal.

The predetermined pressure value may be determined based on a minimum pressure exerted on the seat cushion by an adult, and the sensor may output a first signal (e.g., a low level signal) when the adult sits on the seat cushion portion above the sensor, and a second signal (e.g., a high level signal) different from the first signal when the adult sits on the seat cushion portion above the sensor, so that whether the adult sits on the seat cushion or the child sits on the seat cushion may be determined based on the different signals output by the sensor.

The sensors shown in fig. 4A or 4B described above may be provided in two, or three or more, and these sensors are distributed at intervals of at least a predetermined distance on the axis of symmetry of the seat cushion. In particular, the predetermined distance may be any value between 65-75mm, for example 65mm, 70mm, 75 mm.

For another example, the first sensor may be a structure as shown in fig. 5, that is, the first sensor includes a bottom plate 51, a button 52, and an elastic member 53. The bottom plate 51 is provided with a Hall sensor 511, and one side of the key 52 facing the bottom plate 51 is provided with a magnet 521; alternatively, a magnet is provided on the bottom plate 51, and a hall sensor is provided on the key 52 toward the side of the bottom plate 51. When the pressure borne by the cushion part above the key 52 reaches a preset pressure value, the key 52 is pressed down and drives the magnet to be close to the hall sensor, so that the hall sensor outputs a first signal. The elastic component 53 is arranged on the bottom plate 51 and is used for bouncing the key 52 to drive the magnet to be far away from the hall sensor, so that the hall sensor outputs a second signal.

For another example, the first sensor may have a structure as shown in fig. 6, that is, the first sensor includes a first switch assembly a, a second switch assembly B, a fulcrum O, and a cover C. The fulcrum is fixedly arranged on the bottom plate, the first switch component A and the second switch component B are respectively arranged on two sides of the fulcrum O, and the cover plate C is movably arranged on the fulcrum O through a rotating shaft. When the pressure borne by the seat cushion part above the first switch component A is greater than the pressure borne by the seat cushion part above the second switch component B, the cover plate above the first switch component A is pressed down, and the key of the first switch component A is driven to be pressed down. That is, in the second sensor shown in fig. 6, two switch assemblies form a seesaw structure.

The structures of the first switch assembly a and the second switch assembly B in fig. 6 may be the same, and the structures of the first switch assembly a and the second switch assembly B may be the structures shown in any one of fig. 4A, 4B, and 5.

In some embodiments, two first sensors shown in fig. 6 may be provided on the axis of symmetry of the seat cushion. When the cover of the first sensor X, Y assumes the condition shown in fig. 7A, i.e., no tilt of the cover, it indicates that no one is riding in the vehicle; when the cover of the first sensor X, Y assumes the condition shown in fig. 7B, i.e., the cover is tilted outward, it indicates that a person is riding in the car; when the cover of the first sensor X, Y assumes the condition shown in fig. 7C, i.e., the outer side of the cover is pressed down, it indicates that two persons are riding in the vehicle. The controller may determine the state assumed by the cover plate of the first sensor based on the output values of the two switch assemblies in each first sensor.

In some embodiments, two first sensors and one switch sensor may be provided on the axis of symmetry of the seat cushion, wherein the switch sensor is located between the two first sensors. When the three sensors present the situation shown in fig. 8A, that is, the KEY of the switch sensor KEY2 is bounced and the cover plates of the first sensors KEY1 and KEY3 are not tilted, it indicates that no one is riding in the vehicle; when the three sensors present the situation shown in fig. 8B, that is, the outer sides of the first sensors KEY1 and KEY3 are pressed, it indicates that two persons ride on the vehicle, and the state of the switch sensor KEY2 does not affect the determination result; when the three sensors assume a state as shown in fig. 8C, that is, the outer sides of the first sensors KEY1 and KEY3 are tilted and the KEY of the switch sensor KEY2 is pressed, it indicates that a person takes a car. The controller may determine a state of the cover plate of the first sensor based on output values of two switch assemblies of the first sensor, and determine whether the switch sensor is pressed based on the output values of the switch sensor.

In some embodiments, the sensor may be a second sensor that outputs a switching signal.

For example, the second sensor may have a structure as shown in fig. 9A and 9B, that is, the second sensor includes a base plate 91, an elastic member 92, a cover plate 93, a variable resistor 94, and a circuit board 95. The bottom plate 91 is fixedly arranged in a cavity below the cushion, and the elastic component 92 can be a spring, an elastic sheet and the like. A first end of the elastic member 92 is disposed toward the bottom plate 91, and a cover plate 93 is disposed at a second end of the elastic member. Wherein a first end of the elastic member 92 is disposed on the bottom plate 91, and/or a second end of the elastic member 92 is fixedly disposed on the cover plate 93. The elastic member 92 may be a spring, a leaf spring, or the like.

The variable resistor 94 may be a sliding rheostat or potentiometer, or the like. The variable resistor 94 has a movable portion, which may be, for example, a slide of a slide rheostat, or may be, for example, a rotating shaft of a rotary potentiometer (different angles of the rotating shaft are selected to be considered to reach different positions), a push-pull member of a push-pull potentiometer, or the like. When the position of the movable part changes, the resistance thereof also changes. The movable portion of the variable resistor 94 may move in synchronization with the cover plate 93 or the elastic member. For example, a clamping device is fixedly disposed on the cover plate 93, and the clamping device clamps the movable portion of the variable resistor 94, so that the cover plate 93 moves along with the movable portion when being pressed or bounced; alternatively, the spring is provided with a holding device at a position close to the cover plate 93, the holding device holds the movable portion of the variable resistor 94, and the movable portion is moved by the spring when the spring is compressed.

The circuit board 95 is provided with a signal conditioning circuit, which is connected to the variable resistor 94 and is used for converting the resistance value of the variable resistor 94 into an analog voltage signal or an analog current signal for output. It can be seen that the sensor shown in fig. 9A and 9B is capable of outputting an analog signal.

The controller determines the number of passengers according to the output signals of the sensors, and comprises the following steps: and according to the position of each sensor on the seat cushion symmetry axis, the output values of each sensor are corresponding to the seat cushion symmetry axis, the number of the maximum values in the sensor output values on the seat cushion symmetry axis is determined, and the number of the maximum values with the values larger than a preset threshold value is used as the number of passengers. When the maximum value is determined, it is assumed that the two sensors at the upper edge of the symmetry axis of the seat cushion are respectively provided with a virtual sensor at the outer side, and the values output by the two virtual sensors are 0, that is, it is assumed that the values at the outer sides of the two sensors at the upper edge of the symmetry axis of the seat cushion are 0. The preset threshold is used for distinguishing whether an adult or a child sits on the seat cushion part corresponding to the maximum point. The detailed description may participate in the description of the pressure sensor portion.

In some embodiments, the second sensors may also be distributed in a curved surface. The plane is a special curved surface, so, taking the case of a plane as an example, a plane plate body is arranged below the seat cushion, a plurality of second sensors are arranged on the plate body, for example, the plurality of second sensors can be distributed symmetrically along the symmetry axis as shown in fig. 3B, and one round dot in the figure represents one sensor. Accordingly, the controller determines the number of occupants based on the output signals of the plurality of sensors, including: and according to the position of each sensor on the plane plate body, the output values of the sensors are corresponding to the plane plate body, the number of maximum values in the output values of the sensors on the plane plate body is determined, the number of the maximum values on one side of the symmetry axis of the cushion is determined, and the number of the maximum values with the values larger than a preset threshold value is used as the number of passengers. The preset threshold is used for distinguishing whether an adult or a child sits on the seat cushion position corresponding to the maximum point.
