Description
Technical field
The utility model relates to a kind of intelligent electric motor car sensing device.
Background technology
In recent years, Electrical Bicycle is accepted by consumers in general gradually as a kind of environmental protection, the energy-conservation vehicle, no matter still external at home, Electrical Bicycle sales volume is worldwide also increasing year by year, and the trend that Electrical Bicycle substitutes bicycle progressively enlarges.
Domestic Electrical Bicycle is based on pure electric vehicle at present, American-European countries is then based on Moped Scooter, domestic each tame battery-driven car manufacturer, universities and colleges are also at the research and development intelligent electric bicycle, to open export channel, but can accomplish that from real intellectuality, merchandizing also have a segment distance, being that commonality is poor on the one hand, is that cost is too high on the other hand.
The Electrical Bicycle of band Based Intelligent Control is exactly the intelligent vehicle that we say usually, our power assist system of saying just, in order to reach the purpose of " intelligence ", the designer of China and foreign countries has carried out number of research projects, its purpose has only one, and that is exactly to make the motion of car consistent with people's purpose as much as possible; The height of the size of foot-operated power, speed in frequency when promptly riding according to us, human body satisfy people's purpose to start and the time requirement of coastiong etc.
Occur multiple intelligent electric motor car in the market, adopted torque sensor mostly, its structure more complicated, reliability is also poor, therefore fails to obtain customer's approval all the time, thereby also can't popularize.
Summary of the invention
The purpose of this utility model is: a kind of intelligent electric motor car sensing device is provided, this device is equipped with force transducer and tachogenerator on driving chain, can be when rider's reinforcing and quickening, improve drive torque, play intelligent power-assisted effect, not only simple in structure, and good reliability, low cost of manufacture.
The technical solution of the utility model is: a kind of intelligent electric motor car sensing device, comprise vehicle frame, on the described vehicle frame fixed mount is installed, be connected with the dynamometry lever on the fixed mount, one end of dynamometry lever is provided with tension wheel, and tension wheel is pressed on the driving chain, and the other end of dynamometry lever is connected with spring, spring makes tension wheel compress driving chain all the time, the corresponding force transducer that is provided with between dynamometry lever and the fixed mount.
The further technical scheme of the utility model is: a kind of intelligent electric motor car sensing device, comprise vehicle frame, on the described vehicle frame fixed mount is installed, be connected with the dynamometry lever on the fixed mount, one end of dynamometry lever is provided with tension wheel, and tension wheel is pressed on the driving chain, and the other end of dynamometry lever is connected with spring, spring makes tension wheel compress driving chain all the time, the corresponding force transducer that is provided with between dynamometry lever and the fixed mount; On the described tension wheel tachogenerator is installed.
The more detailed technical scheme of the utility model is: a kind of intelligent electric motor car sensing device, comprise vehicle frame, on the described vehicle frame fixed mount is installed, be connected with the dynamometry lever on the fixed mount, one end of dynamometry lever is provided with tension wheel, and tension wheel is pressed on the driving chain, and the other end of dynamometry lever is connected with spring, spring makes tension wheel compress driving chain all the time, the corresponding force transducer that is provided with between dynamometry lever and the fixed mount; On the described tension wheel tachogenerator is installed; Described spring is extension spring, and an end of spring is connected with the dynamometry lever, and the other end is connected the pulling force of set screw adjustable springs with set screw on the fixed mount.
The utility model has the advantages that:

Fig. 1 scheme of installation of the present utility model;
Fig. 2 is a structural representation of the present utility model.
Wherein: 1 vehicle frame; 2 fixed mounts; 3 dynamometry levers; 4 tension wheels; 5 driving chains; 6 springs; 7 force transducers; 8 tachogenerators; 9 set screw.
The specific embodiment
Embodiment: as Fig. 1, shown in Figure 2, a kind of intelligent electric motor car sensing device, comprise vehicle frame 1,: on the described vehicle frame 1 fixed mount 2 is installed, be connected with dynamometry lever 3 on the fixed mount 2, one end of dynamometry lever 3 is provided with tension wheel 4, tension wheel 4 is pressed on the driving chain 5, the other end of dynamometry lever 3 is connected with spring 6, spring 6 is extension spring, one end of spring 6 is connected with dynamometry lever 3, and the other end is connected the pulling force of set screw 9 adjustable springs 6 with set screw 9 on the fixed mount 2, spring 6 makes tension wheel 4 compress driving chain 5 all the time, the corresponding force transducer 7 that is provided with between dynamometry lever 3 and the fixed mount 2, force transducer 7 can adopt Hall element, and tachogenerator 8 also is installed on the tension wheel 4.
The user is when reinforcing is with acceleration by bike, driving chain 5 can be in tension state, tension wheel 4 is lifted, thereby change the gap between the force transducer 7, and tachogenerator 8 also can measure the variation of speed, the signal of these variations is transferred to control circuit, comes the size of control current output by control circuit, thereby realizes intelligent power-assisted effect.
The utility model is equipped with force transducer 7 on driving chain 5, can improve drive torque when rider's reinforcing and quickening, and plays intelligent power-assisted effect; The utility model also is equipped with tachogenerator 8 on tension wheel 4, adopt the bivariate sensing, more helps the control of microprocessor; Adopt the intelligent electric motor car of torque sensor to compare in the utility model and the present city, have the characteristics of simple in structure, good reliability, low cost of manufacture.
