In the prior art, the charging road adopts a mode of paving an electrode plate on the road surface, the vehicle is provided with a charging electric brush contacted with the electrode plate on the road surface, the charging electric brush of the vehicle is always contacted with the electrode plate to take power in the driving process to supplement the electric quantity for the battery in the vehicle, but in the mode, the electrode plate is exposed in the outdoor environment and is easily influenced by different environments, for example, the road surface is seeped water in rainy days, so that the electrode plate can generate electric leakage in liquid, for example, people or animals pass through the road surface, if the road surface is supplied with power by high voltage, electric shock accidents can easily occur, or the electrode plate can be damaged by stones brought by the vehicle, therefore, more supporting facilities are required to be added in the using process to eliminate the environmental influence, the high voltage can not be used for supplying power, the voltage on the electrode plate can be set at, the current on the electrode plates will become very large, which puts considerable demands on the power supply system.
Based on the underground charging device, the charging road and the charging system thereof, the electrode plate is arranged below the road surface, so that most of the influence of the environment can be avoided, and meanwhile, high-voltage power supply can be adopted, so that the construction of corresponding supporting facilities is reduced, and the power supply requirement of the power supply system is lowered.
The present invention is divided into a vehicle-side device and a road-side device, which complement each other, and for convenience of description, the first and second aspects of the embodiments are explained below as a whole, the basic operation is explained from a whole point of view, and then the specific details of the vehicle-side device and the road-side device are described in detail, respectively.
A first aspect of embodiments of the present invention provides an underground charging apparatus comprising
The telescopic mechanism 100 is arranged on the vehicle, the telescopic direction of the telescopic mechanism 100 faces the road surface and can extend into the lower part of the road surface, an electrode plate 500 connected with a power supply system is arranged below the road surface, and the electrode plate 500 extends along the extending direction of the road surface;
one end of the unfolding mechanism 200 is arranged on the stretching end of the telescopic mechanism 100 and fixed, and the other end of the unfolding mechanism 200 is used as a free end and can be unfolded below the road surface;
and a charging brush 300, the charging brush 300 being disposed at a free end of the deployment mechanism 200 and connected to a battery of the vehicle through a charging cable, the charging brush 300 contacting the electrode plate 500 as the deployment mechanism 200 is deployed.
A second aspect of an embodiment of the present invention provides a charging road, including
An underground cavity 400, the underground cavity 400 comprising at least one opening 410 for passing through the underground charging device according to any one of claims 1 to 6, the opening 410 being opened on the upper side of the underground cavity 400, the upper side of the underground cavity 400 forming a water retaining structure 420 with the road surface;
the electrode plate group comprises two electrode plates 500, the electrode plates 500 are arranged below the water retaining structure 420 and/or on the side wall adjacent to the water retaining structure 420, the electrode plates 500 are connected with a power supply system, and the electrode plate group extends along the extending direction of the road surface.
Referring to fig. 1 to 4, in a cross section of the charging road, the charging road has an opening 410 through which the telescopic mechanism 100 can pass, and when viewed in an extending direction of the charging road, the opening 410 is a groove extending along the extending direction of a road surface, which is equivalent to a charging track, and a vehicle drives the telescopic mechanism 100 to run along the charging track, so long as the charging brush 300 can take electricity from the electrode plate 500 and the rechargeable battery in the vehicle is normally operated, the vehicle can run on the charging road of the present invention while charging; it should be noted that, the charging battery in the vehicle has two charging modes of direct current connection and alternating current connection, and the corresponding electrode plate 500 may also be supplied with direct current or alternating current, but obviously, a plurality of lanes, such as a direct current lane and an alternating current lane, should be distinguished, and each charging lane is arranged in parallel according to the lane division mode of a common road.
It should be noted that, in order to prevent the telescopic mechanism 100 from colliding with the opening 410, the above solution also needs to consider the problem that the vehicle driving direction is aligned with the charging track, since it needs to reserve the road bearing wheel to pass through, so the opening 410 cannot be opened too much, and is slightly wider than the width of the telescopic mechanism 100 at the position of the opening 410, which requires the vehicle to substantially run along the charging track without large deviation during the driving process, here, the vehicle is provided with a corresponding detector, such as a radar or a microwave detection device, to obtain the position of the charging track at the bottom of the vehicle or in front of the vehicle in real time, and automatically adjust the driving direction of the vehicle, such as the existing unmanned vehicle, which is not difficult to achieve this function, and will not be expanded in detail herein. If the telescoping mechanism 100 is fully fixed to the vehicle underbody and does not move relative to the vehicle underbody, even if the vehicle is able to adjust the direction of travel in real time, there is still a certain risk of collision, and the invention is only indicated here as a possible solution, which, with reference to figures 10 and 11, the view angle in the figure is that the telescopic mechanism 100 is connected with a slide rail 600 when viewed from the inside of the vehicle to the road surface, the length direction of the slide rail 600 is perpendicular to the straight running direction of the vehicle, the telescopic mechanism 100 can be offset a certain distance along the slide rail 600, meanwhile, a sensor for detecting the offset is arranged to monitor the offset of the telescopic mechanism 100 on the sliding rail 600, when the vehicle slightly deviates from the driving direction, the telescopic mechanism 100 can move on the slide rail 600 and automatically align with the opening 410, and as long as the maximum offset of the telescopic mechanism 100 on the slide rail 600 is not exceeded, the telescopic mechanism 100 does not violently collide with the edge of the opening 410.
The structure of the charging road is explained in detail below:
in one embodiment, two electrode plates 500 in the electrode plate group are located in the same underground cavity 400, the opening 410 is located in the middle of the upper side of the underground cavity 400, and two water retaining structures 420 are formed on two sides of the opening 410.
The charging road of the present embodiment is a structure of a single charging track, and referring to fig. 5, at this time, two electrode plates 500 are respectively located at both sides of the opening 410, and two charging brushes 300 of the underground charging device extend into the opening 410 and then are respectively unfolded toward the electrode plates 500; preferably, the underground cavity 400 is located at the center of the charging road, and the opening 410 is located at the center of the upper side of the underground cavity 400, as viewed from the cross-section of the charging road.
In order to prevent rainwater and the like from falling down from the opening 410 to the underground cavity 400 due to gravity, the inside of the charging road is inclined downward from the opening 410 to both sides so that the height of the opening 410 is slightly higher than the height of both sides, which has substantially no influence on the traveling of the vehicle.
In another embodiment, the number of underground cavities 400 is two, only one electrode plate 500 is disposed in one underground cavity 400, and the two underground cavities 400 are separated.
The charging road of the present embodiment is a double charging track structure, and two parallel charging tracks are replaced by concrete, etc., so that the double charging tracks divide the charging road into three parts, and the middle part has two forms, the first form is shown in fig. 6, the water blocking structure 420 is connected with the middle part to form a T-shape in the middle structure, the second form is shown in fig. 7, the water blocking structure 420 is connected with the road surfaces at two sides to form a rectangle in the middle structure, accordingly, in order to contact the electrode plates 500 at different positions, the unfolding direction of the unfolding mechanism 200 needs to be adjusted, and the specific structure thereof will be described in detail later.
Also, in order to prevent rainwater and the like from falling down into the underground cavity 400 from the opening 410 due to gravity, both side road surfaces of the charging road of the present embodiment are inclined downward from the middle position to both sides.
In one embodiment, the water retaining structure 420 includes a water resistant lower rim 430, the water resistant lower rim 430 being disposed alongside the opening 410 and extending along the road toward the subterranean cavity 400. The waterproof lower edge 430 in this embodiment is used to prevent objects falling into the underground cavity 400 from scattering in the cavity, and the structure formed by the waterproof lower edge 430 and the opening 410 is equivalent to a short pipe, so that falling objects can be guided, the difficulty in cleaning the underground cavity 400 is reduced, and meanwhile, a part of large objects can be prevented from inclining into the opening 410.
In one embodiment, the bottom of the underground cavity 400 forms drainage ditches 440, and the drainage ditches 440 extend along the extension direction of the road surface and are provided with a drainage port 441 or a decontamination port at intervals. Since the underground cavity 400 extends in the extending direction of the road surface like the electrode plate 500, the underground cavity 400 actually forms a channel as long as the charging road, and the bottom of the underground cavity 400 is used as a drainage ditch 440 in order to clean up impurities, sewage and the like in the underground cavity 400; it should be noted that the depth of the drainage ditch 440 varies from region to region, for example, in a humid and rainy region, the drainage ditch 440 can be made deeper to increase the rainwater capacity; referring to fig. 9, in this embodiment, the drain 440 may be cleaned by a cleaning robot in addition to the drain port 441 or the drain outlet, and a robot inlet is also provided at an interval on the drain 440, and the cleaning robot is periodically or as needed started to clean the drain 440 and return to the robot inlet for servicing.
In order to improve the bonding degree between the electrode plates 500, in an embodiment, two adjacent electrode plates 500 are butted end to end along the extending direction of the road surface, two adjacent water retaining structures 420 are butted end to end along the extending direction of the road surface, a groove 421 perpendicular to the extending direction of the road surface is arranged beside the butted position of the water retaining structures 420, and the two adjacent grooves 421 are fastened through a concave asphalt member 422. Referring to fig. 8, fig. 8 shows a cross-sectional view of the butt joint of the charging road parallel to the extending direction of the road surface, the grooves 421 of the two water-retaining structures 420 are buckled with the concave asphalt pieces 422, and the protrusions on the two sides of the concave asphalt pieces 422 are equivalent to locking the two water-retaining structures 420, so that the structural strength between the water-retaining structures 420 can be enhanced, and the damage of the heavy-duty car to the road surface can be reduced.
The structure of the underground charging apparatus is described in detail below:
in connection with the above-described embodiment of a single charging track, i.e., a road surface having an opening 410, the underground charging apparatus of the present invention adopts the following structure: in one embodiment, the deployment mechanism 200 includes a swing arm 210 and a first rotation mechanism 220, wherein one end of the swing arm 210 is rotatably connected to the extending end of the telescoping mechanism 100 as a rotating end, the other end is connected to the charging brush 300 as a free end, and one end of the first rotation mechanism 220 is connected to a traction mechanism in the vehicle, and the other end is connected to the swing arm 210 for traction. The first rotating mechanism 220 includes a pulling rope 221 and a return spring 222, wherein one end of the pulling rope 221 is fixedly connected to the oscillating arm 210, the other end of the pulling rope is connected to a traction mechanism in the vehicle around the extending end of the telescoping mechanism 100, one end of the return spring 222 is fixedly connected to the oscillating arm 210, and the other end of the return spring is connected to a side wall of the telescoping mechanism 100.
According to the distribution of the electrode plates 500 in the charging road, the number of the charging brushes 300 is two, since the electrode plates 500 are distributed on both sides of the opening 410, the spreading direction of the charging brushes 300 is from the middle to both sides, and the telescopic mechanism 100 can use only one, as an embodiment, referring to fig. 1, when the telescopic mechanism 100 is in a contracted state, the pulling rope 221 is tensioned upwards, the return spring 222 is pulled away, the brush head of the charging brush 300 faces the road surface direction, when the underground charging device starts to work, the telescopic mechanism 100 stretches the charging brush 300 into the underground cavity 400, then the pulling rope 221 is released, the return spring 222 retracts the swing arm 210 to spread towards both sides, that is, the swing arm 210 is tilted upwards from the lowest point, so that the charging brush 300 contacts the electrode plates 500 in the underground cavity 400, when the charging battery in the vehicle recognizes the power supply from the electrode plates 500, the electric control system of the vehicle stops releasing the pulling rope 221, thereby stopping the swing arm 210 at the current angle, achieving stable contact of the electrode plate 500 and the charging brush 300. When it is necessary to terminate the charging, the cord 221 is retracted upward, and the telescopic mechanism 100 is returned to the retracted state.
It should be noted that, according to the structural description of the electrode plate 500 in the charging road, the electrode plate 500 may be disposed below the water blocking structure 420 and/or on a side wall adjacent to the water blocking structure 420, and thus the electrode plate 500 may be disposed at different positions according to different practical application scenarios.
On the other hand, the underground charging device of the present invention does not indicate which part is fixed to the vehicle, and generally, the underground charging device is fixed to the bottom of the vehicle, but considering that the chassis of some vehicles is low, the space in the vehicle cannot accommodate the long telescopic mechanism 100, and the underground charging device can be fixed to the front side of the vehicle, which also facilitates the detection of the charging track by devices such as sensors.
In connection with the above-described embodiment of the double charging track, i.e. the road surface has two openings 410, the above-described underground charging apparatus in the form of the swing arm 210 will be modified in orientation, and referring to fig. 2, two telescoping mechanisms 100 are required on the vehicle and a single charging brush 300 is connected to each telescoping mechanism 100, and the two telescoping mechanisms 100 are respectively inserted into two underground cavities 400, in which case the operation of the underground charging apparatus is similar to that described above and is not repeated once again.
Based on the underground charging apparatus in the form of the swing arm 210, in an embodiment, the deployment mechanism 200 further includes a stop 223 for preventing the swing arm 210 from over-swinging, the stop 223 is disposed beside the rotating end of the swing arm 210 and on a side away from the free end of the swing arm 210, and the stop 223 extends along the extending end of the deployment mechanism 100 to below the road surface. Since the adjustment of the pull rope 221 and the return spring 222 has a certain limit, in order to ensure that the swing arm 210 does not swing beyond a limited angle when being stored back, the swing of the swing arm 210 can be prevented by the baffle 223, and in this embodiment, the baffle 223 extends along the length direction of the telescopic mechanism 100.
In addition to the deployment mechanism 200 in the form of a swing arm 210, as another embodiment, the deployment mechanism 200 may also take the form of:
the deployment mechanism 200 includes a rotatable base 230 and a second rotation mechanism 240, the rotatable base 230 is bar-shaped, the center of the rotatable base 230 is connected to the extension end of the telescopic mechanism through the second rotation mechanism 240, and the charging brushes 300 are disposed at both side edges of the rotatable base 230.
The present embodiment is suitable for a charging road with a single charging track, because the rotatable base 230 can rotate around the second rotating mechanism 240, in an initial state, that is, in a state where the underground charging device is not put down by the vehicle, the length direction of the rotatable base 230 is the same as the extending direction of the charging track, therefore, it can be known that the width of the rotatable base 230 is smaller than the width of the opening 410, when the vehicle needs to be charged on the charging road, the telescopic mechanism 100 puts down the rotatable base 230, so that the rotatable base 230 passes through the opening 410 to enter the underground cavity 400, and then the rotatable base 230 rotates by 90 degrees, at this time, the charging brush 300 can contact the electrode plate 500 under the water blocking structure 420. It should be noted that, in the present embodiment, a form of fixing the second rotating mechanism 240 on the rotatable mechanism is given, that is, the telescopic mechanism 100 is not rotatable, so as to reduce the design complexity of the telescopic mechanism 100, and the second rotating mechanism 240 may be a rotating motor, and is connected to the electronic control system of the vehicle by a wire or wirelessly, etc. to implement the motion control.
Similarly, based on the underground charging device in the form of the rotatable base 230, the telescopic mechanism 100 may have various forms, the telescopic mechanism 100 may be a side-toothed telescopic rod or a spring-type return rod, and may also be a multi-section telescopic rod, which is a common telescopic rod form and is not described in detail herein, and the side-toothed telescopic rod, referring to fig. 3, adopts a combination of a gear and a rack, fixes the gear on a vehicle, the rack is engaged with the gear and one end of the rack is connected to the second rotating mechanism 240 on the rotatable base 230, and by controlling the rotation of the gear, the rack can move up and down, thereby achieving a telescopic effect; the spring type return rod, referring to fig. 4, adopts a combination of a spring, a fixed long rod and a short-range electric push rod, wherein one end of the fixed long rod is connected with an output shaft of the short-range electric push rod, the other end of the fixed long rod is connected with a rotatable base 230, and the spring is connected in series with the output shaft of the short-range electric push rod to provide ejecting thrust.
A third aspect of the embodiments of the present invention provides a charging system, including the underground charging apparatus of any one of the above embodiments and the charging road of any one of the above embodiments, wherein if a vehicle provided with the underground charging apparatus enters the charging road and requests charging, the charging brush 300 is driven by the telescoping mechanism 100 and extends into the underground cavity 400, and the charging brush 300 is driven by the unfolding mechanism 200 and contacts with the electrode plate 500.
Due to the limitation of the charging track, the charging system of the invention is more suitable for the vehicles running on the fixed track or other road vehicles, such as electric buses, heavy electric automobiles and the like, and the lane can not be changed randomly when the vehicles run on the charging road, but the electricity taking device on the automobile can be simplified, and the current on the electrode plate 500 is smaller; on the other hand, because the electrode plate 500 is arranged underground, the influence of severe environments such as rainy days and the like can be effectively avoided, the telescopic mechanism 100 extends from the vehicle to the lower part of the road surface, the charging electric brush 300 is sent to the contact electrode plate 500 below the road surface to provide electric power for the vehicle, so that the vehicle in running can continuously contact the electrode plate 500, the charging effect while running is realized, meanwhile, in a non-charging road section, the vehicle packs the telescopic mechanism 100 without influencing normal running, and because the electrode plate 500 can adopt high-voltage charging and is matched with the charging electric brush 300 on the vehicle, the charging while running of the vehicle is realized, the use of matched measures is reduced, the construction cost is reduced, and the safety performance is improved.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the foregoing and various other changes, omissions and deviations in the form and detail thereof may be made without departing from the scope of this invention.
