Abstract
The utility model relates to an automatic traction regulation device which performs according to gradient variation when electrical bikes climbing slope or getting down slope. Gradient variation information is shown by the displacement between a gravity hammer keeping sagging and a gradient copper sheet which moves along with variation of gradient, the displacement enables a slide contactor to move on the gradient copper sheet, bigger gradient variation, larger the movement scope of the slide contactor is, and the signal electric current come into being makes the relay provide more electric current to the electromotor, which causes the traction becomes larger. The slide contractor and the gravity hammer swing around the same pivot, and the 5 gradient copper sheets are arranged in a circular way while taking this pivot as the center of a circle. In order to eliminate non-gradient information electric current caused by vibration, an interruptable switch is arranged series connected type in the control circuit of the relay.
Description
The utility model is a kind of device of regulating electrical motor tractive force size, is applicable to Electrical Bicycle.
Need toggle switch by hand when existing Electrical Bicycle goes up a slope, the electric current of electrical motor is strengthened, thereby increase the tractive force that goes up a slope; Also need toggle switch by hand during descending, the electric current of electrical motor is reduced or cut-out, allow Electrical Bicycle slide at a slow speed, so that brake.But, make the people when going up a slope, not strengthen electrical motor in time and pull up because the situation on the road is intricate; When descending, reduce tractive force, thereby produce some beyond thought troubles.
From the driving safety angle, the person for driving a car should few as far as possible consideration support hold direction thing in addition.From energy-conservation angle, it is exactly waste that descending has been forgotten to cut off the electricity supply.
The purpose of this utility model is the device of automatically regulating tractive force when creating a kind of Electrical Bicycle uphill/downhill.Use Electrical Bicycle of the present utility model, when uphill/downhill, need not consider the tractive force of electrical motor, also do not need to go to regulate the tractive force of electrical motor with hand, but can be according to the tractive force of the big or small automatically regulating electrical motor of the gradient up and down.
The purpose of this utility model is achieved in that establishes a fulcrum a on a base plate, a side of base plate is the garden heart with a, and b is a radius, and the copper sheet of several mutual insulatings is arranged on arc ground, garden, is called gradient copper sheet.A gravity drop hammer also is installed on the fulcrum a, and this hammer stem can be swung around fulcrum a.Base plate is fixed on the Electrical Bicycle, the axis of fulcrum a is a level, be perpendicular to Electrical Bicycle front and back wheel line again, so when Electrical Bicycle upward slope or descending, when being the inclination of front and back wheel line, gravity drop hammer keeps attitude vertically downward forever, and gradient copper sheet but produces displacement with the inclination of Electrical Bicycle with gravity drop hammer, this displacement also is to be moving of the garden heart with fulcrum a, and mobile range is identical with the residing road grade of vehicle.
From fulcrum b place a copper contact is installed also at gravity drop hammer, is called sliding electricity-connecting head, when gravity drop hammer during around spot wobble, several gradient copper sheets moving contact on sliding electricity-connecting head and the base plate.Like this, when Electrical Bicycle upward slope descending, 5 gradient copper sheets on the base plate will come in contact variation with the sliding electricity-connecting head on the gravity drop hammer, conducting just changes, and suppose Electrical Bicycle when level is advanced, during the promptly zero gradient, it is the conducting of No. 2 gradient copper sheet degree, just becoming the conducting of No. 3 gradient copper sheets when going up a slope so, if uphill gradient is big, then may be No. 4 copper sheets even No. 5 copper sheet conductings.The electric current of number gradient copper sheet conducting that number is big more is big more, so just can realize automatically that it is steep more to climb, and the electric current of connection is big more, the purpose that the tractive force of electrical motor is big more.On the contrary, can connect by the little copper sheet of the number of making number during descending, electric current is reduced, even cut off electric current, make electrical motor tractive force minimum.
For the convenience of installing, we can be on the same one of gravity drop hammer, and another spiral arm is drawn by same dot center, and sliding electricity-connecting head is installed on this spiral arm, and the position is the position of above-mentioned radius b equally.When gravity drop hammer during around spot wobble, sliding electricity-connecting head and spiral arm are together around this spot wobble.The position of above-mentioned gradient copper sheet is also made corresponding mobile in order to cooperate sliding electricity-connecting head, but still is the garden heart with the fulcrum, and b is a radius, and arc ground, garden is arranged.
Such scheme can provide suitable tractive force automatically according to the size of the climbing gradient, can reduce, deduct tractive force during descending automatically, makes person for driving a car's drivings that collect one's thoughts, and is safer, more economize on electricity.
More than be mechanical solution of the present utility model, the existing electric scheme of introducing it again.Battery current is supplied with diverter in this programme, becomes 5 grades of electric currents of size; 5 grades of electric currents of diverter output are given electrical motor by 5 switch Control Allocation on the relay; 5 switches are carried out by 5 gradient copper sheets and sliding electricity-connecting head control respectively on the relay; Relay is carried out coil through switch, signal power source are electrically connected with sliding electricity-connecting head at interval.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structure diagram of the present utility model
1. uphill/downhill information wires, 2. relays, 3. interval switch 4. signal power sources 5. diverters 6. electrical motors 7. batteries 8. sliding electricity-connecting heads 9. spiral arms 10. fulcrums 11. base plates 12. gravity drop hammer 13.14.15.16.17. all are gradient copper sheets among the figure.
The represented state of Fig. 1 is the state that electronic white driving level is advanced, at this moment Electrical Bicycle does not tilt forward and back, base plate (11) keeps the normal position with gravity drop hammer, be that sliding electricity-connecting head (8) contacts with gradient copper sheet (14), the information that copper sheet (14) is given relay is horizontal information, and relay (2) is opened a corresponding electric current and given electrical motor (6).In fact, sliding electricity-connecting head (8) often is in this position, because spiral arm (9) and gravity drop hammer (12) one, and can be around a spot wobble, so gravity drop hammer under the effect of gravity (12) downwards forever, the spiral arm of one and sliding electricity-connecting head also just are in this position forever.When Electrical Bicycle goes up a slope, base plate (11) tilts forward and back with car, sliding electricity-connecting head (8) will slide to gradient copper sheet (15), the gradient of going up a slope is big more, more to lower slider, the information that gradient copper sheet (17) produces is maximum upward slope information, and it can make relay open maximum electric current, to obtain maximum tractive force.
Gradient copper sheet (13) (14) (15) (16) (17) is the garden heart with fulcrum (10), is installed in a side of base plate (11) the garden arc, and fulcrum (10) also is fixed on the base plate (11).Gravity drop hammer (12) is installed on the fulcrum (10), can swing around fulcrum (10).The distance that gradient copper sheet is arranged equals the distance that sliding electricity-connecting head (8) slides, and this distance is by the gradient of Electrical Bicycle uphill/downhill and the length decision of spiral arm (9).Uphill gradient is generally in 30 degree, descending should also have the scope of 30 degree, but I determine descending to cut off electric current when surpassing the scope of 10 degree, no longer stepping reduces electric current, so in fact sliding electricity-connecting head only go up a slope 30 the degree, descending 10 degree, the slip of this 40 degree scope that is to say that 5 gradient copper sheets just are arranged in this 40 degree scope.For the convenience of installing, and guarantee to insulate between the copper sheet, corresponding size must be arranged, after the slip amplitude was determined, this size just had been decided by the length of spiral arm (9), and I am decided to be 6Cm-10cm with the length of spiral arm (9) for this reason.
Because vibration when vehicle is advanced, make the conversion continually that contacts of sliding electricity-connecting head and gradient copper sheet, the big electric current of so direct conducting can very fast damage copper sheet.For this reason, I have adopted relay (2), make on the gradient copper sheet that only by faint signal current (4), the used big electric current of electrical motor is made break-make by relay.But, promptly used relay, also should reduce frequent break-make as far as possible, for this reason, I have sealed in switch (3) at interval again in signal circuit, and pitch time is set at signal of every mistake output in 3 seconds, the signal of the non-uphill/downhill that internal cause vibration in such 3 seconds produces just has been cancelled, it is much steady that information change just seems, by relay and the dual measure of switch at interval, the utility model just can put into practice.
Considering between gradient copper sheet and the cliding joint to have certain contact pressure, and gravity drop hammer can not be too light, should be more than 100g.
So-called interval switch (3) is meant the switch once of conducting after a while, and the time of " after a while " here and " conducting once " all is selectable, has selected 3 seconds in the present embodiment and 0.3 second.
Electrical connection in the enforcement is:
Gradient copper sheet is electrically connected with working coil one end of relay; The other end of relay working coil is with switch, signal power source, sliding electricity-connecting head are electrically connected at interval; Sliding electricity-connecting head slides with gradient copper sheet and is electrically connected; Switch one utmost point on the relay is connected with electric electromechanics; Another utmost point of switch is electrically connected with the diverter mouth on the relay; Another mouth of diverter is connected with electric electromechanics; The input end of diverter is electrically connected with battery.
