Embodiment
A kind of fuel supplying device 10 is described to Fig. 7 with reference to Fig. 1 below.Wherein, Fig. 1 is the view along direction is done shown in the arrow I among Fig. 4.Fig. 3 is the view of being done along arrow III direction among Fig. 4.
This fuel supplying device 10 is applied on the motor, and this motor for example is the float amount mini engine that is used on the sulky vehicle.As shown in Figure 2, fuel supplying device 10 is installed in the fuel tank 1 of sulky vehicle.Fuel tank 1 usefulness resin or metal-molding form.Fuel tank 1 is made into saddle-shaped, so that can stride across the vehicle frame (not shown) of two-wheel vehicle.Fuel supplying device 10 is installed on the sidewall 2 of fuel tank 1, makes that thus the main body of fuel supplying device 10 partly is contained in the fuel tank 1.
Shown in Fig. 1,3,4, fuel supplying device 10 comprises a flange piece 11, a supporting member 20, a pump case 30, a petrolift 31 and a suction filter 40.Suction filter 40 is as a filter component.Flange piece 11 is plate-like pieces of ovalize substantially, and it has sealed the perforate 3 that the sidewall 2 by fuel tank 1 forms.Supporting member 20 is made of resin, and it makes one with jointless form and flange piece.Flange piece 11 and supporting member 20 are to make with the material of the contour oil resistance of POM (polyacetal resin).As alternative, but also metallic material is made flange piece 11 and supporting member 20 integratedly.
Shown in Fig. 3,4, flange piece 11 comprises a connector 12, and this connector is integrated with resin, and comprises a fuel discharge section 13, and it is positioned at flange piece 11 (see figure 2) on the side of fuel tank 1 outside.In addition, a control circuit 50 has been installed on flange piece 11, has been used for petrolift 31 is implemented control.Connector 12 links to each other with the power supply (not shown).Connector 12 is connected with control circuit 50 holding circuits.Shown in Fig. 1,4, the control of the controlled circuit 50 of electric power that comes from power delivery, and export to petrolift 31 by elastic cable paper 51.Elastic cable paper 51 plays the effect of Wiring construction element.The fuel flow guiding that will pump from petrolift 31 by means of fuel discharge section 13 is to the outside of fuel tank 1.
Supporting member 20 is installed in respect on the opposite side of flange piece 11 and connector 12.That is to say that when fuel supplying device 10 was installed on the fuel tank 1, supporting member 20 was installed in the inside of fuel tank 1.Supporting member 20 comprises a cylindrical body 21.As shown in Figure 5, cylindrical body 21 is made into cylindrical shape, so that hold a drainage port 32 of petrolift 31.As shown in Figure 4, the cylindrical body 21 of supporting member 20 is connected with flange piece 11 by a connector 14, and wherein, connector 14 is extended from flange piece 11.The outer radial periphery face of supporting member 20 is being coated by pump case 30.
As shown in Figure 5, supporting member 20 present positions are containing with respect to the outer periphery 11a of flange piece 11.That is to say that if flange piece 11 is carried out projection, then supporting member 20 will be arranged in flange piece 11, and can not go out from the outer periphery 11a projection of flange piece 11.Specifically, when perpendicular to plane, flange piece 11 place (plane among Fig. 5) when it is carried out projection, supporting member 20 will be limited in the scope of flange piece 11 outer periphery 11a, and the outer periphery 11a projection that can not cross flange piece 11 is gone out.
As shown in Figure 5, pump case 30 comprises a cylindrical body 33 and a plurality of support arm 34.The position of cylindrical body 33 is coaxial basically with the cylindrical body 21 of supporting member 20.Shown in Fig. 1,4, pump case 30 utilizes mating part 60 to be assembled on the supporting member 20.Pump case 30 is mounted on the supporting member 20, thereby is supporting pump case 30 by supporting member 20.Thus, the petrolift 31 that is contained in the pump case 30 is just being supported by supporting member 20.
Petrolift 31 is installed in the pump case 30.The drainage port 32 of petrolift 31 is set at supporting member 20 1 sides.The suction port 36 of petrolift 31 is set at a side opposite with supporting member 20.Petrolift 31 comprises a motor and a pressures partially (not shown).The rotation of motor can drive rotating member or the similar component in the pressures partially, thereby produces swabbing pressure.Therefore, 31 pairs of fuel that come from suction port 36 suctions of petrolift pressurize, and fuel is discharged from drainage port 32.
By way of example, brushless type direct current generator can be applied as the motor in the petrolift 31, thereby can cancel the sliding parts between brush and the commutator.In addition, by adopting the direct current generator of brushless, the structure of magnet of stator and rotor-for example and coil can be made simpler.Thereby the axial dimension of motor and radial dimension can both be dwindled.The result is exactly that the size of petrolift 31 can be made very little.In addition, by the cancellation sliding parts, can reduce the loss that petrolift 31 is produced by sliding friction in the course of the work.Thereby, reduced the power consumpiton of petrolift 31.In addition, owing to cancelled sliding parts, can prevent that sliding parts from producing foreign matter, and can prevent that foreign matter from entering into sliding parts.Thereby, can realize the prolongation of operating life, and, although sulky vehicle tends to use inferior fuel, the fault of sliding parts bad connection etc. can not take place yet.
In addition, if with act as a fuel motor in the pump 31 of brushless type direct current generator, the size that then can dwindle petrolift 31, and can reduce requirement of strength to the supporting member 20 that is supporting petrolift 31.Thereby, the size of supporting member 20 can be dwindled, thereby reduce the used amount of resin of supporting member 20.The result is exactly, and can alleviate the flange piece 11 that is made into one and the gross weight of supporting member 20.
The drainage port 32 of petrolift 31 is connected with the fuel channel 22 of formation in the supporting member 20.Fuel channel 22 and the fuel discharge section 13 of flange piece 11 outside that be transported to fuel tank 1 of the fuel of discharging from petrolift 31 through being formed at supporting member 20.The suction port of petrolift 31 is connected with suction filter 40.
Connecting tube 42 comprises one first tubular portion 421, second tubular portion 422 and bending part 423.Bending part 423 couples together first tubular portion 421 and second tubular portion 422.First tubular portion 421 extends upward from filter body 41 along the direction that is substantially perpendicular to suction filter 40 axis.That is to say that first tubular portion 421 extends upward from filter body 41 along the direction of gravity substantially.Second tubular portion 422 is arranged essentially parallel to petrolift 31 axis ground and extends, and with respect to petrolift 31, it is positioned at a side opposite with supporting member 20.First tubular portion 421 and second tubular portion 422 are connected with each other by bending part 423.An end opposite with bending part 423 on second tubular portion 422 is connected on the suction port 36 of petrolift 31.
As mentioned above, supporting member 20 is made one with flange piece 11.Thereby, without any need for the independent member that is used for supporting member 20 and flange piece 11 are coupled together, thereby do not need any position to be set for this independent member is installed yet.Therefore, the number of parts can be reduced, and the specification of fuel supplying device 10 can be reduced.In addition, supporting member 20 and flange piece 11 usefulness resins are made into integration.Thereby, specification and the number of parts can be reduced, and the lightweight of fuel supplying device 10 can be realized.In addition, the size that is installed in petrolift 31 in the fuel tank 1 and supporting member 20 is made very little, thereby can reduce fuel supplying device 10 occupied volume in fuel tank 1.Thereby, need not change the shape of fuel tank 1, just can guarantee the volume of fuel tank 1.
As mentioned above, supporting member 20 is positioned at the inside of flange piece 11 outer periphery 11a diametrically.Thereby, when making supporting member and flange piece 11 integratedly, do not need to make any bottom cutting portion with resin material.The result is exactly, and can and be used for moulded support member 20 and the shape of the shaping die of flange piece 11 can both be made simpler by integrally moulded supporting member that forms 20 and flange piece 11 simultaneously.In addition, make any bottom cutting portion in the shaping die, so the operation of the somatotype of shaping die has just become easily owing to not be used in.Thereby, by the somatotype position of molding mould suitably, can prevent from flange piece 11, to form joint line.Occurring under the situation of joint line,, then will in the contact position of flange piece 11 and fuel tank 1, form a trickle step if forming on the flange piece 11 on joint line-especially be formed at flange piece 11 and the fuel tank 11 contacted outer peripherys.Thereby the airtight quality between flange piece 11 and the fuel tank 1 can descend.In contrast, in this embodiment, do not form any joint line on the flange piece 11, thereby the airtight quality between flange piece 11 and the fuel tank 1 can not descend.Therefore, can stop fuel or fuel fume from fuel tank 1, to let out accurately.
As mentioned above, the pump case 30 that is wherein holding supporting member 20 and petrolift 31 angle that becomes to be scheduled to respect to the major axis of flange piece 11 and minor axis.That is to say that the axis of the axis of supporting member 20, petrolift 31 and the axis of pump case 30 tilt with respect to the major axis and the short-axis direction of flange piece 11.Thereby when those will be accommodated in the supporting member 20 of parts in the pump case 30-for example and petrolift 31 when being assembled, most of parts all are positioned at the inboard of flange piece 11 outer peripherys.Therefore, the perforate 3 that forms on the fuel tank 1 can be limited in the minimum area.
In addition, the axis of petrolift 31 becomes predetermined angle with respect to the axis of suction filter 40.Thereby, but the shape of based on fuel case 1 changes the angle between petrolift 31 axis and suction filter 40 axis alternatively.For example, can change the shape of the connecting tube 42 that is used to connect suction filter 40 and petrolift 31, so that easily change the structural relation between petrolift 31 and the suction filter 40.Therefore, can be with each parts-for example flange piece 11, supporting member 20, petrolift 31, pump case 30, suction filter 40 be made general part, and need not consider which type of shape fuel tank 1 is.In addition, by changing the angle between petrolift 31 axis and suction filter 40 axis alternatively, suction filter 40 can be installed to fuel tank 1 diapire 4 near, and need not consider which type of shape fuel tank 1 is.Even under the situation that fuel reduces in fuel tank 1, petrolift 31 also can stably be pumped into fuel the outside of fuel tank 1 therefore.
Referring to Fig. 6, on gravitational direction, be shaped on support arm 34 on the upside of the cylindrical body 33 of pump case 30 and the downside.Claw 62 from the part ring side face of supporting member 20 to the radial outside projection.Claw 62 extends on the circumferencial direction of supporting member 20.Thus, the mating part 60 that forms between supporting member 20 and pump case 30 is positioned at upside and the downside on the gravitational direction.Wherein installed this fuel supplying device 10 equipment-for example the vibration of two-wheel vehicle on Vertical direction (moving up and down) is greater than the vibration on the left and right directions, left and right directions wherein is for gravitational direction.That is to say that fuel supplying device 10 is installed on such equipment: the vibration on its Vertical direction is greater than transversely vibration.
On gravitational direction (Vertical direction), mating part 60 lays respectively at the upside and the downside of supporting member 20 and pump case 30, thereby forms vertically arranged structure, can guarantee to have enough supporting forces between supporting part 20 and the pump case 30 thus.Supporting member 20 can produce relative movement up and down with pump case 30 on gravitational direction.In this case, the length of engaging zones will increase, and wherein, in engaging zones, perforate 61 is bonded with each other in moving direction (on the Vertical direction) with claw 62.The result is exactly, in addition at supporting member 20 and pump case 30 on the gravitational direction up and down under the situation of relative movement, can prevent that also mating part 60 from getting loose mutually.
To explain the reason that to guarantee to have between supporting member 20 and the pump case 30 enough support forces why below.When supporting member 20 and pump case 30 produced relative movement up and down on gravitational direction, pump case 30 can swing up and down around mating part 60.Thereby pump case 30 will be that fulcrum curves with respect to supporting member 20 with mating part 60.
Herein, consider to be different from the above-mentioned situation that is arranged vertically structure, mating part 60 can be disposed in a lateral direction, that is to say, mating part 60 can be arranged to and the Vertical direction quadrature.In the structure of this lateral arrangement, mating part 60 is positioned on the direction vertical with plane, Fig. 1 place.In this lateral arrangement structure, when pump case 30 is a fulcrum when curving in vertical direction with mating part 60, the internal face 61a that forms perforate 61 on claw 62 and the pump case 30 will be in contact with one another (seeing Fig. 6,7) at the upper end of claw 62 62a or lower end 62b place.Thereby the area of contact of the internal face 61a of formation perforate 61 is corresponding to the cross-section area of claw 62 on claw 62 and the pump case 30.Herein, the cross-section area of claw 62 is areas of claw 62 upper end 62a and lower end 62b.The gross area of upper and lower end 62a, 62b is less than total face area of the end 62c of claw 62.The result is exactly that in the structure of lateral arrangement, upper end 62a and lower end 62b possibly can't produce enough supporting forces between claw in the mating part 60 62 and perforate 61.Thereby, if claw 62 is arranged on supporting member 20 and the pump case 30, then forms on claw 62 and the pump case 30 between the internal face 61a of perforate 61 and be easy to throw off according to horizontal direction, thus make pump case 30 be easy to supporting member 20 on separate.
In contrast, in the type that the is arranged vertically structure of this mode of execution, mating part 60 is set on the upper and lower of supporting member 20 and pump case 30.Be arranged vertically in the type structure this, when pump case 30 is a fulcrum when curving with mating part 60, the internal face 61a of perforate 61 is in contact with one another on the end 62c of claw 62 and the pump case 30.In Fig. 6,7, the end 62c of claw 62 is positioned at the relative both sides of pump case 30.Thereby the area of contact between claw 62 and the pump case 30 internal face 61a is corresponding to the face area of claw 62 end 62c.
Herein, shown in Fig. 6,7, the shape of claw 62 end 62c is square basically, and the shape of claw 62 upper end 62a and lower end 62b then is a triangle.When claw 62 is essentially on the internal face that square end 62c, the upper and lower end 62a that is generally triangular and 62b be forced into 30 perforates 61 of pump case, compare with 62b with the upper and lower end 62a that is generally triangular, more be not easy to deform for square end 62c substantially.
The result is exactly, and in being arranged vertically the type structure, engaging between claw 62 and the perforate 61 strengthened, thereby exists under the situation of vertical vibration, and engaging between supporting member 20 and the pump case 30 is difficult to unclamped.Therefore, the situation that mating part 60 is arranged perpendicular to gravitational direction in the lateral arrangement type structure-be the situation that mating part 60 is in horizontal direction, in this embodiment, the support force between supporting member 20 and the pump case 30 can obtain to guarantee fully.
Shown in Fig. 1,5, petrolift 31 comprises a wiring part 37, and in this part, the distribution of drawing from motor exposes to the external world.Wiring part 37 is connected with control circuit 50 by elastic cable paper 51.As shown in Figure 3, control circuit 50 comprises an intergrated circuit (IC) 52, integrated electrical device and microcomputer on this intergrated circuit.50 pairs of control circuits flow to the electric current of motor and other device in the petrolift 31 and carry out regulation and control, with drive motor.In the fuel supplying device 10 on being applied to small displacement engine, to petrolift 31 fuel dispatch amounts require relatively low.Thereby, also very little to the demanded power output of motor in the petrolift 31.The result is exactly, and can reduce the performance of the electrical device that is used for drive motor, and IC52 also can be made smaller.Therefore, the control circuit 50 that has an IC52 can be installed to the outside of flange piece 11.In addition, as shown in Figure 4, be used for the elastic cable paper 51 that control circuit 50 and wiring part 37 couple together can be supported by a supporting element 15 that is installed on the flange piece 11.
Referring to Fig. 3,4, on a side of fuel tank 1 outside, it has connector 12 (see figure 2)s at flange piece 11.Control circuit 50 is installed in flange piece 11 on the surface in fuel tank 1 outside.One side of elastic cable paper 51 1 inside from flange piece 11 towards fuel tank extends to the fuel tank 1.Supporting member 20 is installed in flange piece 11 on a side of fuel tank 1 inside.
At petrolift 31 in the radial direction, wiring part 37 is positioned on the side opposite with flange piece 11.Thereby as shown in Figure 1, elastic cable paper 51 extends around the end of supporting member 20, so that connect with the wiring part 37 of petrolift 31, wherein, the described end of supporting member and the position opposite of pump case 30.Thereby, be connected to the position of petrolift 31 at elastic cable paper 51, have very big spatial margin (see figure 2).Fuel supplying device 10 is being made in the design of small size type, need reduced the distance between supporting member 20 and the flange piece 11, and need reduce pump case 30 that beared part 20 supporting and the distance between the flange piece 11.Thereby, by way of example,, then elastic cable paper 51 and wiring part 37 are coupled together and will have difficulties if wiring part 37 is installed in flange piece 11 1 sides (for petrolift 31).In contrast, in this embodiment, at petrolift 31 in the radial direction, wiring part 37 is set at respect on the opposite side of petrolift 31 and flange piece 11.Thereby elastic cable paper 51 has very big spatial margin with the coupled position place of petrolift 31 wiring parts 37.
In addition, on the ring Zhou Fangxiang of petrolift 31, wiring part 37 is positioned between two mating parts 60.That is to say that as shown in Figure 5, on the circumferencial direction of pump case 30, wiring part 37 is positioned between two support arms 34.Two mating parts 60 are disposed in upside and the downside place on the weight direction, thereby support arm 34 is not disposed on the position that is substantially perpendicular to gravitational direction.Thereby, on wiring part 37 residing positions, support arm 34 is not set, so just can arrange support arm 34 and wiring part 37 effectively.Therefore, can prevent the volume expansion of pump case 30.
As mentioned above, supporting member 20 connects together at mating part 60 places by means of matching relationship with the pump case 30 that is wherein holding petrolift 31.Thereby, petrolift 31 can be easily mounted on the supporting member 20.In addition, two mating parts 60 are arranged to be in the upper and lower part with respect to gravitational direction.Thereby even there is very big vertical vibration as two-wheel vehicle, the engagement relationship of the mating part 60 that forms between claw 62 and support arm 34 perforates 61 internal face 61a also is not easy to throw off.Therefore, supporting member 20 can firmly support petrolift 31.
At petrolift 31 in the radial direction, the wiring part 37 of petrolift 31 is disposed in a side opposite with flange piece 11.Thereby, even reduced distance between flange piece 11 and the supporting member 20 owing to dwindling fuel supplying device 10, also can the position of large space surplus links up elastic cable paper 51 and wiring part 37 having very.Therefore, can easily petrolift 31 be assembled into elastic cable paper 51.
On the circumferencial direction of petrolift 31, wiring part 37 present positions are between two mating parts 60.That is to say that wiring part 37 is positioned between the support arm 34, formed the perforate 61 of mating part 60 on the support arm 34.Thereby support arm 34 and wiring part 37 can be arranged on the circumferencial direction of petrolift 31 efficiently.Therefore, the pump case 30 that is wherein holding petrolift 31 is easy to be made into undersized, thereby can reduce the size of fuel supplying device 10.
Shown in Fig. 1,5,8, petrolift 31 comprises wiring part 37, and in this part, elastic cable paper 51 is drawn out to the outside of petrolift 31 from motor.Elastic cable paper 51 plays the effect of conductive connecting line.Shown in Fig. 8,9,10, wiring part 37 can be designed to like this: make elastic cable paper 51 and the pump side connector 38 that stretches out from petrolift 51 link.As alternative, as shown in figure 11, wiring part 37 can be designed to like this: need not any connector, the motor (not shown) of pump cable 39 from petrolift 31 extended.For petrolift shown in Figure 11 31, pump cable 39 can directly be connected with connector 12 (see figure 3)s on the flange piece 11, scheme as an alternative, and pump cable 39 links with elastic cable paper 51 extending on the path of connector 12.Therefore, extending on the path of flange piece 11 connectors 12, the wiring part 37 of drawing from petrolift 31 is connected with elastic cable paper 51.
Wiring part 37 is connected with control circuit 50 by means of elastic cable paper 51.As shown in Figure 3, control circuit 50 has intergrated circuit 52, integrated electrical device and microcomputer on this intergrated circuit.50 pairs of control circuits flow to the electric current of motor in the petrolift 31 and carry out regulation and control, with drive motor.As situation in the present embodiment, for the fuel supplying device 10 that is applied in the small displacement engine, to petrolift 31 fuel dischargeable capacities require relatively low.Thereby, also very little to the demanded power output of motor in the petrolift 31.The result is exactly, and can reduce the performance of the electrical device that is used for drive motor, and IC52 also can be made smaller.Therefore, the control circuit 50 that has an IC52 can be installed to the outside of flange piece 11.
