Description
Technical field
It the utility model is related to multi-speed bicycle, more particularly to a kind of automatic transimission for multi-speed bicycle.
Background technology
Automatic speed-changing bicycle on the market is usually to carry out gear change control according to torque or speed at present, if touched
To it is continuous go up a slope be difficult ride on go, so only relying on torque and speed is defined and carries out automatic gear and control this mode not
Practicality, experience of riding are also very poor.
Utility model content
The technical problems to be solved in the utility model is, in view of the shortcomings of the prior art, there is provided one kind be used for speed change from
The automatic transimission of driving.
In order to solve the above technical problems, the utility model adopts the following technical scheme that.
A kind of automatic transimission for multi-speed bicycle, includes drain pan, and the drain pan is provided with two journal stirrups, electricity
Machine, angular transducer and wiring board, screw mandrel, slide bar and nut are provided between two journal stirrups, the screw mandrel and slide bar are set parallel
And the two both passes through nut, the nut is connected with wire rod thread, and the nut is slidably connected with screw mandrel, fixed on the nut
Have a shift cable, the motor is electrically connected at wiring board, and the wiring board includes MCU, the MCU by controlled motor just,
Invert and make nut slide back and forth, and then drive shift cable movement；MCU and the angular transducer electrical connection.
Preferably, the drain pan is provided with battery, and the battery is used to power to motor and wiring board.
The disclosed automatic transimission for being used for multi-speed bicycle of the utility model, its by upward slope state according to car
Body angle change carries out gear change control, ensure that automatic speed-changing bicycle ride go up a slope during ride ride comfort, power
The harmony of square, good experience of riding can be obtained.
Brief description of the drawings
Fig. 1 is the exploded view of the utility model automatic transimission.
Embodiment
The utility model is described in more detail with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of automatic transimission for multi-speed bicycle, it includes drain pan 1, on the drain pan 1
Provided with two journal stirrups 2, motor 6, angular transducer 9 and wiring board 7, screw mandrel 3, slide bar 4 and nut 5 are provided between two journal stirrups 2,
The screw mandrel 3 and slide bar 4 are set parallel and the two both passes through nut 5, and the nut 5 is threadedly coupled with screw mandrel 3, the nut 5
It is slidably connected with screw mandrel 3, shift cable 8 is fixed with the nut 5, the motor 6 is rotated for drive screw 3 to make nut 5
Slided along slide bar 4, the motor 6 is electrically connected at wiring board 7, and the wiring board 7 includes MCU, and the MCU is by controlling electricity
Machine 6 is positive and negative then makes nut 5 slide back and forth, and then drives shift cable 8 to move, and the MCU and angular transducer 9 are electrically connected.Angle
Degree sensor 9 is used for the change for perceiving car body angle, and generates electric signal transmission to wiring board 7 and include MCU, wiring board 7
MCU and then completion gear shift operation control.
Specifically, in the present embodiment, the drain pan 1 is provided with battery 13, and the battery 13 is used for motor 6 and wiring board
7 power supplies.
Operation principle of the present utility model is：Angular transducer 9 perceives the change of car body angle, and generates electric signal transmission
Include MCU, the MCU of wiring board 7 and then completion gear shift operation control to wiring board 7.
The utility model is in practice, it is possible to achieve including under upward slope pattern, level road pattern and upward slope pattern switching
The control of slope pattern.Include two or more gearshift mechanism in upward slope pattern, gearshift mechanism is according to the gradient of upward slope
Size corresponds to corresponding gear shift section, and the gradient is bigger, and the lower gradient of gear of gearshift is bigger, and the gear of gearshift is lower, ensure that
Automatic speed-changing bicycle ride go up a slope during ride ride comfort, torque harmony, good experience of riding can be obtained.
In level road pattern, gearshift gear limitation is preset；In upward slope pattern switching descending pattern, gear is directly jumped by low-grade
Go to high tap position.Meanwhile the threshold value that user can prestore with setting angular transducer of being controlled oneself according to ride custom and the muscle power controlled oneself,
Upward slope pattern, level road pattern and upward slope pattern switching descending pattern are actuated for controlling, can obtain preferably, be suitable for
The experience of riding of oneself.
Simply the utility model preferred embodiment described above, is not limited to the utility model, all in this practicality
Modification, equivalent substitution or improvement made in new technical scope etc., should be included in the model that the utility model is protected
In enclosing.
