The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with drawings and Examples.
Now please refer to Fig. 1, wherein show the blast split three-dimensional view of a vehicle speed setter 10, this vehicle speed setter 10 is installed in the vehicle.Usually this vehicle is driven by an internal combustion engine, and this engine has speed control mechanism, in order to control the speed of this vehicle.
This vehicle speed setter 10 comprises a main body 32, a stay reel 20, a speed drag-line 26 and an enclosing cover 22 substantially.Being skillful in present technique person can understand, and have devices such as a CD-ROM drive motor, a power-transfer clutch, a gear cluster and a control circuit in this main body 32 substantially.This main body 32 can be fixed in the vehicle by a support 50.The control circuit of this main body 32 is connected with cruise control in the operator's saddle by control line 35, in order to control this vehicle speed setter 10.When this driver sets constant speed, can mesh the power-transfer clutch of this main body 32, and, make one on this main body 32 drive bolt 30 and driven by this CD-ROM drive motor by this power-transfer clutch and this gear cluster.Otherwise, when this driver removes constant speed, can discharge the power-transfer clutch of this main body 32, then this driving bolt 30 can return back to by the device of spring-like and so on the particular radial.
Now please refer to Fig. 1,2 and 3, this stay reel 20 is made of two plectanes 45,47 and a centre portion 43 substantially, and this two plectane 45,47 has the opening 46 of alignment, and forms the two side in order to settle a cable wire.This centre portion has the circular arc 42,44 of two different radiis substantially, and as shown in the figure, the radius of this circular arc 42 is greater than the radius of this circular arc 44.This stay reel 20 is fixed on this driving bolt 30 of this main body 32 by a nut 38.This speed drag-line 26 has a vertical piece 27 and a cable wire 29.The piece 27 that should hang down just can embed in this opening 46 of this stay reel 20, and a part that makes this cable wire 29 is between this two plectane 45,47, and the other end of this cable wire 29 is connected with the speed control mechanism of this vehicle.
As previously mentioned, when this driver sets constant speed, control path in this main body can rotate this CD-ROM drive motor, and by this driving bolt 30, this stay reel 20 is turned to a particular radial, so with cable wire 29 pulling one segment distance of this speed drag-line 26, with the speed control of this vehicle in present speed.Yet, in different vehicles, the needed stroke of this speed control mechanism, that is the distance of these cable wire 29 required pullings is also inequality.When this stay reel 20 is installed on this vehicle speed setter 10 with as shown in Figure 2 direction, this cable wire 29 is wound on the less circular arc of this radius 44, that is be somebody's turn to do when driving bolt 30 rotations one angle (direction of arrow as shown in the figure), the stroke that this cable wire 29 is spurred is less.Otherwise, when this stay reel 20 when being installed on this vehicle speed setter 10 with as shown in Figure 3 direction, this cable wire 29 is wound on the bigger circular arc of this radius 42, that is is somebody's turn to do when driving bolt 30 rotations one angle (direction of arrow as shown in the figure), and the stroke that this cable wire 29 is spurred is bigger.
Therefore, the circular arc 42,44 of two different radiuses makes this vehicle speed setter 10 just to be installed in the vehicle of different types, and can be complementary with the speed control mechanism of this vehicle easily by this stay reel 20 of counter-rotating thus.Being skillful in present technique person can understand, the circular arc of different types can be installed in this stay reel, for example, the centre portion of this stay reel can be helical, and this opening 46 lays respectively in the different radial positions, when this drove bolt 30 rotations one special angle, this cable wire 29 can be pulled different strokes in view of the above.
Moreover, when this vehicle speed setter 10 uses stay reel 20 of the present invention, because this speed drag-line 26 does not change with the relative position of this stay reel 20, no matter that is how this stay reel 20 to rotate, this cable wire 29 can be pulled but be unlikely the angle of change with respect to this speed drag-line 26.So this speed drag-line 26 can firmly be fixed on this main body 32 by an anchor fitting 28.
Again since this cable wire 29 between this anchor fitting 28 and this stay reel 20,, can easily this cable wire 29 be led so pass through a sidewall 34 of this enclosing cover 22.So set when this driver removes constant speed, and when discharging this drivings bolt 30, this cable wire 29 can be this sidewall 34 and leads and be unlikely distortion, and causes this vehicle speed setter 10 faults.
The stay reel 20 of vehicle according to the invention cruise control 10 because the intermediate portion has different radiuses, so this vehicle speed setter 10 can be installed in the vehicle of different types, can be complementary with the speed control mechanism of this vehicle simultaneously.
Though the present invention discloses with aforementioned preferred embodiment, so it is not in order to limiting the present invention, anyly has the knack of this operator, without departing from the spirit and scope of the present invention, and when doing various changes and modification.Therefore protection scope of the present invention is when being as the criterion with claims.
