Description
Technical field
The invention belongs to the technical fields of charging equipment of electric automobile, and in particular to a kind of installation of electric car charging bow
Structure.
Background technique
Currently, electric car is just gradually promoted, and especially in urban public transport field, more and more buses
Using electric car.Due to the limited energy of electric car, it is therefore desirable to website charging is stopped in road, it is domestic at present most
Number electric car realizes that charge power supply is connect with charging vehicle from carriage side using charging gun, and then separately some is electric in recent years
Electrical automobile uses the type of attachment that charge power supply and charging vehicle are realized from compartment top surface.It charges to be realized from compartment top surface,
It will use the charging bow worked in coordination and pantograph.The charging of electric car, which is bent, is mounted on a charging for two charging electrodes
Bend the bottom surface of bracket, charging bow then supports by vertical base and is suspended in the spatial position for being higher than car body top；Charging
When bow is mounted on road, vertical base must be located on the pavement of road, without being located on road surface, with obstruction free
Vehicle pass-through.The compartment top surface of electric vehicle is mounted on the pantograph of charging bow cooperation, and pantograph cradle top sets that there are two naked
Dew by electrode.
When charging, electric automobile during traveling to charging bow it is following after pause, then, make charging bend two charging electrodes with by
Two of pantograph from vertical adjacent to each other and force together and contact, are realized electrical connection and charging by electrode.Charging bow
The metal that strip generally is by electrode of charging electrode, electric car, and the length of the charging electrode for the bow that charges is to general
Decussation contact is formed to, the two perpendicular to the length by electrode of electric car, in this way, the stop position of automobile can
To there is an allowable error range by a relatively large margin, automobile stop position accuracy when charging requires not tight.
Existing electric car charging bow mainly has fixed charging bow and two kinds of bow of descending manner charging.
Fixed charging bow refers to: charging bow is fixed, and by the vertically movable adjusting of pantograph on electric car；When
Automobile is parked when charging is bent below bracket and prepares charging, makes pantograph using by the vertical position regulating mechanism on electric car
The vertically raised charging electrode for touching charging bow；Kept pantograph vertical by the vertical position regulating mechanism on electric car after charging
Decline.Obviously, the vertical position regulating mechanism that fixed charging bow needs that every automobile is allowed to be equipped with pantograph, thus cost
It is higher.
Descending manner charging bow refers to: charging bow is equipped with vertical position regulating mechanism；When automobile it is parked below the charging rack simultaneously
Fixed by the pantograph on electric car when preparing charging, the vertical position regulating mechanism using charging bow bends charging
Charging electrode decline and touch by electric car by electric electrode；Made on charging bow after charging using vertical position regulating mechanism
It rises.Due to charging bow quantity than electric car much smaller number, thus descending manner charging bow cost is relatively low.
In addition, two charging electrodes of existing charging bow are all that left and right is arranged side by side (being to arrange laterally side by side).With this
It is corresponding it is matched is that pantograph two of existing electric car are that left and right is arranged side by side (i.e. cloth laterally side by side by electrode
It sets).This is because when charging, the charging electrode of the bow that charges and electric car by needing Elastic Contact between electrode, without
It can be by the way of very stiff and demanding, for this purpose, needing to be lined with reset spring, reset spring between each charging electrode and charging bow bracket
Downward pressure is applied to charging electrode, the deformation of reset spring makes the vertical relative position between charging electrode and charging bow bracket
Can finely tune, when charging, the reset spring of charging electrode by electric car the upward pressure applied by electrode and pressed
Contracting, and the following table face contact electric car of charging electrode by electric electrode top, and after charging complete, left by electrode
The reset spring of charging electrode, charging electrode stretches down, and the vertical position of charging electrode will decline, thus, it is supposed that will fill
Two charging electrodes 3 of pantograph 2 are arranged as relationship one in front and one in back, and (two of corresponding automobile pantograph 92 are by electrode 91
It is also disposed to as relationship one in front and one in back, as shown in Figure 1, the forward direction of automobile is as shown by arrows in Fig. 1), then just in case vapour
Vehicle surprisingly start to advance during the charging process or charging complete after charging bow is unexpected does not pack up and automobile has started to moving ahead
Into shown in direction of travel arrow as shown in Figure 1, Figure 2, the charging that will lead in charging electrode 3(i.e. Fig. 2 of front on the right side of drawing is electric
Pole 3) snap onto inside two axial clearances by electrode 91, then by will lead to front charging electrode 3 and it is subsequent by
In electrode 91(, that is, Fig. 2 on the left of drawing by electrode 91) clash collision, finally pull bad by force front charging electrode 3
Or the bow bracket 2 that can also make entirely to charge by electrode 91, when serious at rear knocks down, and pounds the serious thing of people or electric shock
Therefore., whereas if two charging electrodes or so are arranged side by side (being to arrange laterally side by side), even if then unexpected advance occurs for automobile
Afterwards, will not there are charging electrode and the danger by the mutual collision that conflicts of both electrodes.
It (is cloth laterally side by side that two charging electrodes of existing charging bow, which are all that left and right is arranged side by side, due to the above reasons,
Set), and be arranged symmetrically at left and right sides of compartment top surface.
In addition, relatively large Rechargeable vehicle is mostly bus, the width of the carbody of bus is big, so, for
Rest in for the bus on the right of road, carriage top left side of face by electrode, at a distance from edge on the right of road surface
Typically at least reach three meters or so, correspondingly, the charging electrode of charging bow typically at least reaches at a distance from edge on the right of road surface
To three meters or so.Since charging bow is difficult to significantly move, existing descending manner charging bow Shortcomings: charging bow is upper
After rising after (non-charged state) or decline (charged state), projected position is all located at right above road surface, that is, is located at automobile
The surface of driving trace line, in this way, the landscape of road had not only been seriously affected, but also there are larger security risks, specifically, working as horse
When road has the automobile violating the regulations of the serious superelevation of loading, charging bow just has the security risk blown down, will appear touching when serious
Electrification.
In present specification, consider which direction be laterally, which direction is when being longitudinal, when bending work with charging, by electricity
The front-rear direction of automobile is longitudinal direction, and the left and right directions by electric car is laterally.
Summary of the invention
A kind of electric car charging bow mounting structure is provided it is an object of the invention to overcome disadvantages mentioned above, it is being not required to
The surface of road surface will not be located at when charging, reduce the influence to road landscape, and avoid the vehicle broken rules and regulations by superelevation
It scrapes, and even if charging electrode will not occur and by both electrodes when Rechargeable vehicle charges after the advance of generation accidental activation
Mutual conflict collision problem, it is ensured that safety.
Its purpose can be realized by following scheme: a kind of electric car charging bow mounting structure, including vertical base, charging
Bend bracket, there are two charging electrodes for the bottom surface installation of charging bow bracket, are mainly characterized by, in vertical base upper end and charging

For lower balance staff, the articulated shaft between upper pendulum bar and charging bow bracket is upper articulated shaft, the hinge between draft link and charging bow bracket
Spindle is lower articulated shaft；Upper balance staff, lower balance staff, upper articulated shaft, lower articulated shaft are parallel to each other and extending direction is longitudinal；On
The distance between balance staff central axis and bottom axis center axis are equal to upper jointed shaft center axis and lower jointed shaft center axis
The distance between, the plane that both upper balance staff central axis and bottom axis center axis determine is parallel to jointed shaft center axis
The plane determined with both lower jointed shaft center axis；Driving upper pendulum bar and draft link are additionally provided with around respective on vertical base top
The swing driving mechanism that balance staff is swung；Two charging electrodes one in front and one in back arranged of the charging bow cradle bottom surface；Each
It is also lined with reset spring between charging electrode and charging bow bracket, reset spring applies downward pressure to charging electrode, resets bullet
The deformation of spring enables the vertical relative position between charging electrode and charging bow bracket to finely tune, and is located at the charging electrode in front
The amplitude peak of fine tuning is d；When two charging electrodes of charging bow bracket are in non-charged state without by extraneous effect upwards
When power, the lower surface of charging electrode of the lower surface than being located behind of the charging electrode positioned at front is high, the height difference of the two
For h, and h > d.
It is preferred that h >=the 2d.
It is preferred that h >=2 centimetre.
So-called " two charging electrodes of charging bow bracket are in non-charged state without by extraneous upward active force ", it is practical
On refer to upward pressure of two charging electrodes not by electric car by electrode, also not by other extraneous upward
Active force, at this time under the action of reset spring, two charging electrodes are in its scope of activities most relative to charging bow bracket
Lower section.
The present invention has the following advantages and effects:
One, the swing mode of present invention charging bow bracket is horizontal swing；When not needing charging, charging can be driven
Bend bracket swing, since the extending direction of upper balance staff, lower balance staff is longitudinal direction, thus the bow bracket that charges is swung up generation cross also
To movement, i.e., perpendicular to vehicle heading transverse shifting, which is also perpendicularly to road extending direction, therefore the bow that charges
Bracket can swing laterally surface close to vertical base when not needing charging, will not be located at road surface just on
Reduce the influence to road landscape in side, it is often more important that avoid being scraped by the vehicle of superelevation, it is ensured that safety.
No matter two, what angle charging bow bracket swings to, charging is bent bracket and the relative pose on ground and will not all be changed,
That is it is constant that two charging electrodes are always maintained at posture directed downwardly, further bring in this way of both act on, 1, ensure the bow that charges
The charging electrode of the bottom surface of bracket will not directly be poured by rain；2, regardless of how high the compartment by electric car is, charging bow bracket is swung
To after compartment top surface, the lower surface of charging electrode is all kept immediately below downward, therefore can be adapted for the vapour of any different height
Vehicle.
Three, the charging electrode one in front and one in back arranged of the bottom surface of the charging bow bracket can make charging bow bracket
Lateral dimension significantly reduces, and two of corresponding automobile can be all disposed within the right edge in compartment by electrode, thus may be used
The lateral distance of charging electrode Yu road surface edge is greatly reduced, the power that charging bow bracket is rotated around balance staff is greatly reduced
Arm lengths (can be reduced to 1 meter or less) in practice, reduce torque needed for swinging laterally, upper pendulum bar, draft link is greatly reduced
Overhanging stress, keep entire mounting structure light and handy, save cost, also providing premise for horizontal swing design may be (if horizontal
It needs to amplitude of fluctuation at three meters or more, then total stress is very big, it will very huge, heavy).
Four, when two charging electrodes of charging bow bracket are in non-charged state without by extraneous upward active force, institute
Rheme is high in the lower surface of charging electrode of the lower surface of the charging electrode in front than being located behind, and the difference in height of the two is h, and
And h is greater than d (d is the amplitude peak that the charging electrode in front is finely tuned)；In this way, even if automobile surprisingly starts during the charging process
Advance forward or charging complete after charging bow bracket do not pack up surprisingly and car engine is advanced forward, also can be avoided and fill
The charging electrode of pantograph bracket and the mutually card that occurred by electrode of automobile collide.
