Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in the figure, the sliding contact electricity taking device for the electric automobile comprises a rotary swing arm assembly, a supporting and positioning assembly, a positive electrode electricity taking slide rod assembly and a negative electrode electricity taking slide rod assembly.
The rotary swing arm assembly comprises a rotary platform 1, a support 2 arranged on the rotary platform, a swing arm 3 with one end hinged on the support, and a driving mechanism 4 arranged on the rotary platform and used for driving the swing arm to rotate up and down around a hinged shaft. The rotary platform is in the prior art, and can be driven by a stepping motor or a servo motor in specific implementation, so that the rotation angle of the rotary platform can be accurately controlled. In this embodiment, the driving mechanism 4 includes an electric cylinder 41 vertically fixed on the rotating platform and a U-shaped groove block 42 disposed on the end of the telescopic rod of the electric cylinder, and the swing arm is located in the U-shaped groove block; of course, in different embodiments, the electric cylinder can be replaced by an air cylinder or a hydraulic cylinder; and the driving mechanism 4 for driving the swing arm to deflect up and down can be in more forms, and other forms can be adopted in different embodiments.
The supporting and positioning assembly comprises a positioning plate 5 arranged in the middle of the swing arm and large in upper part and small in lower part, a supporting plate 6 matched with the positioning plate and a lifting driving mechanism 7 positioned at the bottom of the supporting plate and used for driving the supporting plate to lift, and a positioning groove 8 matched with the positioning plate in shape is formed in the supporting plate. In this embodiment, the positioning plate 5 is a trapezoidal plate with a large upper part and a small lower part, the positioning groove is a trapezoidal groove matched with the positioning plate in shape, and the thickness of the supporting plate is larger than that of the positioning plate, so that the position of the supporting plate can adapt to the change of the position of the positioning plate caused by the vertical deflection of the swing arm. In this embodiment, the lifting driving mechanism 7 is an electric cylinder arranged vertically, and of course, in different embodiments, the electric cylinder may be replaced by an air cylinder or a hydraulic cylinder.
The positive pole electricity-taking sliding rod assembly 9 and the negative pole electricity-taking sliding assembly 10 are identical in structure and respectively comprise a sliding rod 11, upright rods 12 hinged to two ends of the sliding rod and a tension spring 13, one end of the tension spring is connected to the sliding rod, and the other end of the tension spring is connected to the upright rods.
In a specific implementation, the rotary swing arm assembly can be one set or two sets. When the rotary swing arm assembly is a set, as shown in fig. 1, the positive pole electricity-taking slide bar assembly and the negative pole electricity-taking slide bar assembly are arranged at the end part of the swing arm of the rotary swing arm assembly. As shown in fig. 2, when the number of the rotary swing arm assemblies is two, the positive pole electricity-taking slide bar assembly and the negative pole electricity-taking slide bar assembly are respectively arranged on the end parts of the swing arms of one rotary swing arm assembly.
The electric vehicle sliding contact power taking device of the embodiment has the following action process when taking power:
when electricity is needed to be taken, the lifting driving mechanism drives the swing arm to ascend, so that the slide rods of the positive pole electricity taking slide rod assembly and the negative pole electricity taking slide rod assembly are respectively contacted with the positive pole power supply lead and the negative pole power supply lead.
When the electric automobile runs on a lane under the positive power supply lead and the negative power supply lead, the lifting driving mechanism drives the supporting plate to be in contact with the positioning block all the time, and the lifting supporting assembly is supported in the middle of the swing arm, so that the stability of the swing arm in the running electricity taking process can be enhanced.
When the electric automobile runs from the lane under the positive power supply lead and the negative power supply lead to another lane, the lifting driving mechanism drives the supporting plate to move downwards to be separated from the positioning block, at the moment, the swing arm is lifted by the driving mechanism 4 to support the swing arm, and the power supply lead drives the swing arm to rotate. Electric automobile sliding contact gets electric installation in this embodiment, its rotary platform gets the electric process at the sliding contact and always rotates for passively, and rotary platform's motor is out of work promptly, and when going at the vehicle lane change, the pole setting and the power supply wire contact on the electric slide subassembly are got to the positive pole, and the pole setting is given the atress for swing arm and rotary platform, and rotary platform passively rotates and makes swing arm self-adaptation vehicle lane change circumstances of going.
In the specific implementation, when the lane change distance of the vehicle is too large, if the lane change is performed at a turnout, the tension of the power supply lead on the swing arm overcomes the elastic force of the spring to enable the vertical rod to deflect to the horizontal state, and at the moment, the sliding contact power taking device of the electric vehicle is separated from the power supply lead, and meanwhile, the damage of the power taking device cannot be caused. After the turnout is branched, the motor of the rotary platform works, and then the swing arm is rotated to the middle of the vehicle again, so that preparation is made for re-getting electricity.
As an improvement to the above embodiment, the bottom of the positioning block is provided with a first electromagnet 14, and the vehicle is provided with a first electric control switch for controlling the strength of the first electromagnet; the middle part of the positioning groove of the supporting plate is provided with a second electromagnet 15, and a second electric control switch for controlling the electromagnet intensity of the second electromagnet is arranged on the vehicle.
When the electric automobile is in the lane under anodal power supply wire and the negative pole power supply wire and traveles, lift actuating mechanism drives layer board and locating piece contact all the time to first electro-magnet and second electro-magnet circular telegram make locating plate and layer board adsorb together, because swing arm length is great, the inertial force that the swing arm received when the emergency brake appears in the vehicle is great, and the swing arm can assault the power supply wire forward, probably causes the power supply wire to damage. This improvement adsorbs through first electro-magnet and second electro-magnet together for can avoid the swing arm to strike the problem that the power supply wire caused the power supply wire to damage when the vehicle emergency brake.
And when the vehicle is driven in a lane change way and the swing arm deflects downwards to separate the positive pole electricity taking slide bar assembly and the negative pole electricity taking slide bar assembly from the power supply lead, the first electromagnet and the second electromagnet are not electrified.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
