Example 1
Referring to fig. 1, fig. 1 is a schematic structural diagram illustrating an electric bicycle according to an embodiment of the present invention, and an electric bicycle 100 according to an embodiment of the present invention includes a rainfall sensor 101, a speed sensor 102, an umbrella 103, and a central processing unit 104;
the rainfall sensor 101, the speed sensor 102 and the umbrella 103 are all electrically connected with the central control processor 104;
the rainfall sensor 101 is used for detecting a rainfall value and sending the rainfall value to the central control processor 104;
the speed sensor 102 is used for detecting the current vehicle speed and sending the current vehicle speed to the central control processor 104;
before the umbrella 103 is not opened, the central control processor 104 is used for judging whether the current vehicle speed is higher than a preset vehicle speed threshold value when the rainfall value is higher than the preset rainfall threshold value; if not, the umbrella 103 is controlled to be opened; if yes, the vehicle speed is reduced until the current vehicle speed is not higher than the vehicle speed threshold value, and then the umbrella 103 is controlled to be opened.
It can be understood that, since the electric bicycle 100 provided by the embodiment of the present invention needs to detect the rain amount through the rain sensor 101, a piece of transparent glass is installed on the electric bicycle 100 for the rain sensor 101 to detect the rain amount. Regarding the installation position of the transparent glass and the rainfall sensor 101, the embodiment of the invention only requires that the transparent glass can effectively contact the falling rainwater after the transparent glass and the rainfall sensor 101 are installed, so that the rainfall value detected by the rainfall sensor 101 is accurate.
Optionally, in an implementation manner provided by the embodiment of the present invention, the rain sensor 101 is installed in the headlamp of the electric bicycle 100, and the transparent glass corresponding to the rain sensor 101 is a lamp cover of the headlamp. It should be understood that the embodiment of the present invention merely provides a preferred installation position of the rainfall sensor 101, and the installation position of the rainfall sensor 101 can be adjusted according to actual requirements in actual production and use.
Further, the central control processor 104 has preset therein a corresponding logic processing circuit, which is configured to determine whether the rainfall value exceeds a preset rainfall threshold value in real time after receiving the rainfall value sent by the rainfall sensor 101, and if so, it represents that the current weather may cause a negative impact on the riding of the user, and therefore the umbrella 103 needs to be opened to assist the user in riding; the central control processor 104 also determines whether the current speed exceeds a preset vehicle speed threshold, if so, it represents that the current speed is too high, the opening of the umbrella 103 may have a negative effect on riding of the user, or the umbrella 103 is easily damaged when being opened, and therefore the umbrella 103 is controlled to be opened only after the vehicle speed is reduced until the current speed does not exceed the preset vehicle speed threshold.
It can also be understood that the central control processor 104 may first determine whether the rain amount value is higher than the rain amount threshold, then determine whether the current vehicle speed is higher than the preset vehicle speed threshold, or first determine the current speed and then determine the rain amount value, or determine at the same time, and the embodiment of the present invention does not limit the sequence of determination of the rain amount value and the current speed, so that the logic processing circuit in the central control processor 104 may also be adjusted according to actual requirements; and the rainfall threshold and the preset vehicle speed threshold can also be set according to actual requirements.
From this, when the user rides electric bicycle 100 and meets with weather, electric bicycle 100 will control umbrella 103 and open and shield the rainwater with the help user, carry out speed control according to the current speed of traveling that detects, avoided the user rainy day can't go out through electric bicycle 100, or through the comparatively dangerous condition of electric bicycle 100 trip to effectively promoted the user and ridden electric bicycle 100 in rainy day and experienced.
Preferably, in an implementation provided by the embodiment of the present invention, the speed sensor 102 and the central processing unit 104 may be both disposed inside a seat of the electric bicycle 100; the umbrella 103 can be arranged at the middle point of the two handles, and when the vehicle does not rain, the umbrella 103 is in a folding state, and the umbrella 103 is vertical to the horizontal ground. It should be understood that the embodiment of the present invention is merely to provide a preferred mounting position for the speed sensor 102, the central control processor 104 and the umbrella 103, which can be adjusted according to actual requirements in actual production and use.
In addition, the central control processor 130 in the embodiment of the present invention determines that the rainfall value is higher than the preset rainfall threshold, and when the current vehicle speed is not higher than the preset vehicle speed threshold, the umbrella 103 is controlled to be opened to assist riding. In an implementation manner that can be realized by the embodiment of the present invention, the electric bicycle 100 also controls the umbrella 103 to open when it determines that the rainfall value is higher than the preset rainfall threshold and the current vehicle speed is zero. From this, guaranteed that electric bicycle 100 also can not drenched when rainy day, had both avoided all kinds of devices on electric bicycle 100 to drench to prolong the life of device, still enabled the user and kept away from the wind and rain temporarily under electric bicycle 100, it is more humanized, and can make the direct use of electric bicycle 100 of user, need not to wipe dry cushion or handlebar hand, and then improved user's use experience.
Optionally, in an implementation manner provided by the embodiment of the present invention, the electric bicycle 100 further includes a wind speed sensor;
the wind speed sensor is electrically connected with the central control processor 104;
the wind speed sensor is used for detecting the current wind speed and sending the current wind speed to the central control processor 104;
if the umbrella 103 is opened, the central control processor 104 is further configured to reduce the vehicle speed until the current vehicle speed is not higher than the preset gale safety vehicle speed when the current wind speed is higher than the preset wind speed threshold, where the preset gale safety vehicle speed is smaller than the vehicle speed threshold.
Specifically, when a user rides in a rainy day, the umbrella 103 will certainly have a certain influence on riding after being unfolded. When the wind speed is too high, the umbrella 103 may have a certain influence on the driving sight of the user or may be detached from the electric bicycle 100.
Therefore, in the embodiment of the invention, the current wind speed is detected in real time through the wind speed sensor, the detected current wind speed is sent to the central control processor 104, the central control processor 104 further judges whether the current wind speed is higher than the preset wind speed threshold value, if so, the current wind speed is over high, riding and driving safety of a user can be influenced, and the electric bicycle 100 is controlled to decelerate, so that influence of the wind speed on riding of the user is reduced, and driving safety of the user is ensured.
Preferably, in an implementation manner provided by the embodiment of the present invention, the wind speed sensor is disposed below any one of the handlebars. It should be understood that the embodiments of the present invention are merely intended to provide a preferred mounting position for a wind speed sensor, which can be adjusted according to actual requirements in actual production and use.
Further, in an implementation manner provided by the embodiment of the present invention, the electric bicycle 100 further includes a wind direction sensor and a direction sensor;
the wind direction sensor and the direction sensor are both electrically connected with the central control processor 104;
the wind direction sensor is used for detecting the current wind direction and sending the current wind direction to the central control processor 104;
the direction sensor is used for detecting the current driving direction and sending the current driving direction to the central control processor 104;
if the umbrella 103 is opened, the central control processor 104 is further configured to determine a current relative driving speed according to the current vehicle speed, the current wind direction and the current driving direction, and reduce the vehicle speed until the current relative driving speed is not higher than a preset relative speed threshold when the current relative driving speed is higher than the preset relative speed threshold, where a vehicle speed corresponding to the preset relative speed threshold is less than a strong wind safe vehicle speed.
It can be understood that after the electric bicycle 100 controls the umbrella to be opened, wind speed and wind direction are one of the factors affecting the riding of the user. For example, the same wind speed has a distinct effect on the acceleration of the electric bicycle 100 in different wind directions, the higher the wind speed in the downwind condition, the easier the electric bicycle 100 is to accelerate, and the more difficult the electric bicycle 100 is to accelerate in the upwind condition, so that the effect of the electric bicycle 100 on the riding of the user is different in different wind directions.
Therefore, in order to ensure safe riding of the user in different wind directions, the embodiment of the invention adjusts the speed of the electric bicycle 100 in real time based on the detected driving direction, wind speed and current speed, so as to ensure the riding safety of the user in rainy days.
Furthermore, in an embodiment provided by the embodiment of the present invention, the wind direction sensor is installed below any one of the handles, and the direction sensor is installed inside the seat. It should be understood that the embodiments of the present invention are merely intended to provide a preferred installation location of the wind direction sensor and the direction sensor, which can be adjusted according to actual requirements in actual production and use.
Further, in an embodiment provided by the embodiment of the present invention, the umbrella 103 in the electric bicycle 100 includes an umbrella handle;
if the umbrella 103 is opened, the central control processor 104 is further configured to determine a rainwater falling reference direction according to the current wind speed, the current wind direction and the current driving direction, and control the umbrella shaft of the umbrella 103 to be in the same direction as the rainwater falling reference direction.
It is understood that the falling direction of the rainwater is greatly influenced by the wind direction and the wind speed, and when the electric bicycle 100 is in the driving process, the falling direction of the rainwater needs to be referred to the driving direction of the vehicle. It can also be understood that in this embodiment, the traveling speed of the vehicle is not higher than the preset relative speed threshold, and therefore, when calculating the rain falling direction with the electric bicycle as a reference, i.e., the rain falling reference direction, the current vehicle speed is regarded as a constant, and the influence of the current vehicle speed on the rain falling direction is not excessively considered.
Exemplarily, taking fig. 2 as an example, fig. 2 shows a schematic driving diagram of an electric bicycle according to an embodiment of the present invention, which includes an origin of coordinates, X and Y axes, a vector a, a vector B, and a vector C. The coordinate origin can be regarded as a vehicle, the direction of the vector A is regarded as a wind direction, the mode of the vector A is regarded as a wind speed, the direction of the vector B is regarded as a current driving direction, the mode of the vector B is regarded as a current vehicle speed constant, the vector C is a vector sum of the vector A and the vector B, and the direction of the vector C can be regarded as a rainwater falling reference direction. It is understood that rain that can fall on the electric bicycle 100 during the driving of the electric bicycle 100 is actually determined by the vector a and the vector B, i.e., the vector C. And when the modulus of vector B is constant, vector C is more affected by the directions of vector a and vector B. Therefore, the influence of the vehicle speed is not excessively considered in determining the rain water falling reference direction.
Further, in this embodiment, the umbrella 103 is physically connected to the electric bicycle 100 through the umbrella shaft. Furthermore, the handle of the umbrella 103 is perpendicular to the horizontal ground, and if the rain falls in the direction different from the direction of the umbrella handle, the effect of the umbrella 103 shielding the rain is reduced, and the riding experience of the user is affected.
Therefore, in the embodiment of the invention, after the current rainwater falling reference direction is determined through the central control processor 104, the wind speed sensor, the wind direction sensor and the direction sensor, the central control processor 104 adjusts the umbrella handle of the umbrella 103 to be in the same direction as the rainwater falling reference direction, so that when rainwater drifts to a user from different directions, the umbrella 103 can effectively shield the rainwater, thereby reducing the influence of wind and rain on the riding of the user and further improving the riding experience of the user.
Optionally, in an implementation manner provided in the embodiment of the present invention, the electric bicycle 100 further includes a communication module;
the communication module is electrically connected with the central control processor 104;
the communication module is used for receiving a vehicle unlocking instruction and sending the vehicle unlocking instruction to the central control processor 104;
the central control processor 104 is further configured to control the umbrella 103 to open when the vehicle unlocking instruction is received and the rainfall value is higher than the preset rainfall threshold.
It can be understood that the communication module is not only used for receiving a vehicle unlocking command, but also used for receiving at least one of a vehicle locking command, a vehicle temporary locking command, and the like, and the embodiment of the present invention does not additionally limit the functions of the communication module.
It can also be appreciated that if the user needs to ride the electric bicycle 100 in the rainy day, but the electric bicycle 100 can control the umbrella 103 to open only after unlocking, which will result in the user waiting for the umbrella 103 to open before riding. Before the electric bicycle 100 is unlocked, the electric bicycle is generally in a stationary state, that is, the current vehicle speed is less than the preset vehicle speed threshold and is zero.
Therefore, after the central control processor 104 receives the vehicle unlocking instruction through the communication module, it can determine whether to control the umbrella 103 to open according to the rainfall value detected by the rainfall sensor 101, and no longer determine whether the current vehicle speed is higher than the preset vehicle speed threshold. Therefore, the time for the user to wait for the umbrella 103 to be opened is reduced, and the vehicle using experience of the user is improved; also, even if the user is not near the electric bicycle 100, the electric bicycle 100 can open the umbrella 103 while unlocking, so that the user can hide rain by the opened umbrella 103 immediately after reaching the location of the electric bicycle 100 and immediately start riding.
Furthermore, in one embodiment of the present invention, the communication module may be a part of the central processor 104; in yet another embodiment, the communication module may be a physical device mounted in the vehicle seat. It should be understood that the specific installation/configuration of the communication module may be adjusted according to the actual situation.
Optionally, in an implementation manner provided by the embodiment of the present invention, the electric bicycle 100 further includes a weight sensor;
the weight sensor is electrically connected to the central processor 104;
the weight sensor is used for detecting the current bearing weight of the electric bicycle 100 and sending the current bearing weight to the central control processor 104;
the central control processor 104 is further configured to control the umbrella 103 to open when the rainfall value is higher than the preset rainfall threshold and the current bearing weight is higher than the preset weight threshold.
It is understood that a weight sensor may be installed in a seat of the electric bicycle 100 to detect a weight change on the vehicle, thereby obtaining a current bearing weight. And the central control processor 104 determines that the current bearing weight exceeds the preset weight threshold, which represents that a person sits on the electric bicycle 100.
It can also be appreciated that when the user rides the electric bicycle 100 to the destination but is still raining, if the vehicle is returned and the umbrella 103 is stowed, the user will be caused to get wet by the rain.
Therefore, the embodiment of the invention judges whether the electric bicycle 100 is ridden by a person according to the weight sensor and the central control processor 104, and controls the umbrella 103 to be opened to provide a rain shielding space if the electric bicycle 100 is ridden by the person, so that a user can temporarily shield the electric bicycle 100 from wind and rain, and the electric bicycle 100 is more humanized and intelligent.
