Description

Technical Field

[0001] The present invention relates to the technical field of vehicle power supply, and in particular to a road side wall power supply device. Background Art

[0002] New energy vehicles, especially electric vehicles, are gradually becoming an important force in the transportation field. They store electrical energy through batteries and are driven by electric motors without relying on traditional internal combustion engines, thus reducing dependence on fossil fuels and environmental pollution. The charging methods of electric vehicles mainly include slow charging and fast charging. Slow charging is usually carried out at home or public charging stations, which takes a long time and is suitable for vehicles parked at night or for a long time; while fast charging uses high-power charging equipment to charge more electricity into the battery in a shorter time, which is suitable for long-distance driving that requires rapid energy replenishment. In addition, some electric vehicles support battery replacement mode, that is, quickly replacing battery packs at special battery replacement stations to shorten energy replenishment time. With the development of electric vehicle technology, battery life is constantly improving, charging facilities are also continuously improving, the convenience and popularity of electric vehicles are gradually increasing, and the government and enterprises are actively promoting the widespread use of electric vehicles by providing car purchase subsidies and building charging networks, contributing to the realization of green travel and sustainable development.

[0003] At present, the charging method of new energy vehicles, whether it is battery replacement or traditional charging, inevitably requires the vehicle to stop driving in the service area to complete charging or battery replacement. Especially during holidays, the service area is one of the places with extremely large traffic volume, and its limited space strictly limits the number of vehicles that can be accommodated. When the number of vehicles exceeds the carrying capacity of the service area, it may cause serious traffic congestion. In addition, whether it is charging or battery replacement in the service area, the vehicle needs to enter and stop for a period of time to complete these operations. This stagnation not only affects the smooth operation of the service area, but also brings additional pressure to the daily management of the service area.

[0004] To solve this problem, the research and development direction of new energy vehicles is moving towards an innovative charging technology, that is, the vehicle can be charged while driving without stopping at a service area. The development of this technology aims to reduce the power consumption of new energy vehicles on the road, thereby avoiding the vehicle's stop at a service area and effectively reducing the operational burden of the service area. In this way, new energy vehicles can obtain the required power without interrupting driving, which not only improves the efficiency of vehicle use, but also helps to alleviate the congestion problem caused by vehicle charging or battery replacement in service areas.

[0005] For example, in the prior art, Comparative Document 1, which is a lateral charging device for new energy vehicles with a publication number of CN116605073A, and Comparative Document 2, which is a non-stop green charging system suitable for highways with a publication number of CN220220434U, both disclose technical solutions to achieve charging of the battery of the new energy vehicle during its driving process. Comparative Document 1 forms a charging skateboard through the tail wing to contact the charging structure, and performs charging in the process, while Comparative Document 2 performs charging by direct contact between the pantograph on the vehicle and the roadside cable. The method provided by Comparative Document 1 always keeps the surface contact between the vehicle and the charging structure. During the driving process of the vehicle, due to the surface contact between the two, when the vehicle drives the displacement and the charging skateboard displaces, there is a large friction force when contacting the charging structure. The tail wing itself is a deflectable structure with limited structural strength. When the speed of the vehicle increases, The friction between the charging skateboard and the charging structure will act on the rotation point of the tail wing with the total length of the charging skateboard and the tail wing as the lever arm, which is very likely to cause it to break. It is not suitable for the highway environment. Comparative Document 2 uses the vehicle to drive the pantograph to move. It only needs to set up a cable on the side of the road. When the two are in contact, charging can be carried out. However, if the pantograph needs to be in direct contact with the cable for power, then the metal wire in the cable is also required to be exposed to the air so that the pantograph and the metal wire can be in contact for power. Once it rains, the electric energy in the cable will leak when the rain acts as a conductor. Once there are people or other creatures nearby, electric shock casualties will occur directly. Therefore, this solution is not suitable for the current requirements on highways for new energy vehicles to charge while driving. Therefore, it is necessary to provide a relatively complete road side wall power supply device that is not prone to damage to solve the above problems.

DETAILED DESCRIPTION

[0057] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0058] A road side wall power supply device, such as Figure 1-11 As shown, it includes a road electrification component and a vehicle power collection component;

[0059] The road electrification assembly includes a vertically arranged insulating lining 1, two power supply boards 2, and a waterproof assembly and a drainage assembly;

[0060] Two power supply boards 2 are installed on the insulating liner 1, and the two power supply boards 2 are respectively coupled with a positive wire 6 and a negative wire 7;

[0061] The waterproof component is arranged above the insulating liner 1 to block rainwater from top to bottom;

[0062] The drainage assembly is installed on the insulating lining 1 and is located below the power supply board 2 to receive and discharge rainwater flowing from the power supply board 2;

[0063] The vehicle current collecting assembly includes a telescopic assembly and a current collecting wheel 8;

[0064] The collector wheel 8 is rotatably connected to the movable end of the telescopic assembly through the wheel axle 13, and the telescopic assembly is used to be installed on the vehicle, and the wheel axle 13 is coupled to the battery of the vehicle through a wire.

[0065] The insulating lining 1 fixes the power board 2, the insulating barrier bar 3, and the back of the protective beam 42 to the right side of the column, and blocks the electrical contact between the column and the power board 2, providing insulation protection between the power board 2 and the column. Because it is exposed to the air and often exposed to the sun and rain, it must be made of insulating and weather-resistant plastic materials, such as PVC polyvinyl chloride materials.

[0066] When the collector wheel 8 is working, its elastic telescopic rod 22 will continue to maintain a certain range of tension to the left. The power supply board 2 is not only the track plane for the collector wheel 8 to roll, but also maintains electrical contact with the collector wheel 8. The contact surface of the power supply board 2 is exposed to the air for a long time, and metal materials with good conductivity, strong rigidity, wear resistance and corrosion resistance must be used, such as copper-clad flat steel. The back and upper and lower edges of the power supply board 2 must be covered and sealed with insulating materials to maintain good insulation. Such as polyethylene plastic materials to reduce the risk of accidental electric shock. Only one side of the power supply board 2 facing the road is exposed to maintain electrical contact with the collector wheel 8.

[0067] When the vehicle is driving on the road, the vertical height variation range is normally controlled within the maximum up and down travel range of the shock absorbing system. The width of the power supply board 2 is greater than the maximum up and down travel range of the vehicle plus the width of the collector wheel 8, so that the collector wheel 8 can roll within the track plane of the power supply board 2 and maintain electrical contact.

[0068] Preferably, it also includes an insulating seam 4 and a dump power-off switch 5 .

[0069] The power supply board 2 is a flat metal plate with a large length and very low elasticity. A gap must be reserved at the power board joint, and the gap is filled with elastic insulating material, such as silicone adhesive material, to avoid the power supply board 2 and its supporting structure from being damaged due to thermal expansion and contraction of the power supply board 2 due to temperature changes. The collector wheel 8 maintains stable operation when passing through the gap, and at least one collector wheel 8 at each pole maintains electrical contact, so that the electric vehicle can continuously obtain electrical energy from the power supply board 2.

[0070] A tipping switch is connected between each power supply board 2 and the cable and fixed on the back of the power supply board 2. When the power supply board 2 accidentally tips over, the power supply can be automatically cut off to avoid short circuit or leakage.

[0071] Preferably, the collector wheel 8 comprises a hub and a conductive wheel ring;

[0072] The conductive wheel ring surrounds the outer side of the wheel hub;

[0073] The conductive wheel ring and the wheel hub are both made of conductive material.

[0074] The conductive wheel ring is the outer ring of the collector wheel 8, which can roll and slide along the track plane of the power supply board 2 and maintain electrical contact. It uses materials with good conductivity, easy processing, and lower hardness than the power supply board 2, such as copper and its alloys. The conductive wheel ring has multiple screw holes with uniform spacing, and the bolts matched therewith use the same material as the conductive wheel ring. The wheel ring and the split design of the wheel ring can make the hub use high-strength and light materials, such as aluminum alloy, to reduce the weight of the collector wheel 8 and facilitate the replacement of the outer ring that is easy to wear. The outer ring of the hub reserves multiple screw holes with uniform spacing, and the hub and the conductive wheel ring are fixed by bolts. The bolt head has a safety wire hole, and the spokes also reserve wire holes, and the steel wire can pass through or wrap around. All safety wire holes are passed through and connected with low-carbon steel wire, and then the wire ends are tightened to prevent the bolts from loosening, and it is convenient to replace the conductive wheel ring after it is worn. The wheel ring and the split design of the wheel ring can make the hub use high-strength and light materials, such as aluminum alloy, to reduce the weight of the collector wheel 8 and facilitate the replacement of the outer ring that is easy to wear. The outer ring of the hub is reserved with multiple screw holes at even intervals, and the hub and the conductive wheel ring are fixed by bolts. The bolt head has a safety wire hole, and the spokes also have wire holes reserved, through which the steel wire can pass or wrap. Pass low-carbon steel wire through all the safety wire holes and connect them, then tighten the wire ends to prevent the bolts from loosening and facilitate the replacement of the conductive wheel ring after wear.

[0075] Preferably, the telescopic assembly includes a tool holder 10, a connecting rod 9, a nut 12, and an elastic reset ring;

[0076] The wheel axle 13 is fixedly connected to the tool holder 10, and the collector wheel 8 is rotatably connected to the outer ring of the wheel axle 13, and the tool holder 10 is rotatably connected to one end of the connecting rod 9;

[0077] The nut 12 is fixedly connected to the connecting rod 9 in the length direction, and the elastic reset ring is sleeved on the outer ring of the connecting rod 9, and the two ends of the elastic reset ring are respectively in contact with the tool holder 10 and the nut 12.

[0078] The tool rest 10 is made of a material with good rigidity, light weight and electrical conductivity, such as aluminum alloy. The connecting rod 9 is fixed at the center point of the tool rest 10, and the wheel axle 13 of the collector wheel 8 is fixed at both ends.

[0079] Connecting rod 9, cut one end of the stainless steel square tube into a semicircle, and drill a hole at the center of the semicircle, the hole diameter is the same as the axle sleeve, the sleeve length is the same as the side length of the square tube section, and the axle sleeve is welded to the inside of the square tube hole. Insert the axle (bolt) into the hole of the tool holder 10, gasket, square tube, gasket, tool holder 10, lock the nut, and leave a gap and sufficient lubrication so that the tool holder 10 can rotate horizontally flexibly. Then use low-carbon steel wire to pass through the safety line hole at one end of the screw rod to prevent the nut from loosening.

[0080] The elastic reset ring is fixed on the connecting rod 9 near the tool holder 10 and is made of highly elastic material, such as silicone. In the absence of external force, the reset ring remains perpendicular to the connecting rod 9. When the road is on a curve, the curb power supply board 2 is also a curved arc, and the angle between the tool holder 10 and the connecting rod 9 must also change to remain parallel to the power supply board 2. When the angle on one side is less than 90 degrees, the tool holder 10 will squeeze the elastic reset ring, and the reset ring will also form a reaction force on the tool holder 10. When the collector wheel 8 leaves the power supply board 2, this reaction force can restore the tool holder 10 to a state perpendicular to the connecting rod 9.

[0081] Preferably, the telescopic assembly further includes a cylinder 31, a push spring 33, a piston 32, and an elastic telescopic rod 22;

[0082] The piston 32 is slidably connected in the cylinder 31;

[0083] The push spring 33 is located in the cylinder body 31, and the two ends of the push spring 33 are in contact with the inner bottom surface of the cylinder body 31 and the piston 32 respectively;

[0084] One end of the elastic telescopic rod 22 is fixedly connected to the piston 32 , and the elastic telescopic rod 22 passes through the cylinder body 31 and is transmission-connected to the connecting rod 9 .

[0085] The push spring 33 keeps the collector rod under tension to the left, and can apply tension to the tool holder 10 regardless of whether it is on a straight road or a turn, so that the tool holder 10 remains parallel to the power supply board 2; at the same time, the tension of the push spring 33 can also reduce the impact force of the collector wheel 8 on the power supply board 2 when it approaches the power supply board 2 in a moving state, and the elastic telescopic rod 22 passes through the cylinder body 31 with a non-circular opening, so that the collector rod cannot be rotated, and its cross-sectional shape is wedged with the shape of the collector rod, and a gap is left for sufficient lubrication, so that the collector rod can reciprocate smoothly laterally.

[0086] Preferably, a rainproof insulating connecting tube 17 is provided at the connection between the connecting rod 9 and the elastic telescopic rod 22;

[0087] The outer ring of the rainproof insulating connecting tube 17 is provided with a rainproof cover 18, and the rainproof cover 18 has openings at both ends, and the cross-sectional areas of the openings at both ends are different. The opening with a small cross-sectional area is gap-matched with the outer ring of the rainproof insulating connecting tube 17, and a drainage hole communicating with the interior is opened at the bottom of the rainproof cover 18;

[0088] The rain cover 18 is penetrated by a plurality of support screws 20 arranged from outside to inside, and a water blocking cup 21 is sleeved on the outer ring of the support screw 20 located at the bottom.

[0089] When the vehicle is driving in rainy weather, the surface of the connecting rod 9 may get wet, and the connecting rod 9 and the elastic telescopic rod 22 are connected by the insulating connecting tube, so that the connecting rod 9 and the elastic rod can be kept insulated.

[0090] A bottomless beverage bottle-shaped rain cover 18 is placed outside the rainproof insulating connecting tube 17 to prevent rainwater from splashing onto part of the connecting tube. The bottle mouth is small, so that rainwater is not easy to enter the rain cover 18. The bottle mouth is provided with a water retaining stem to drain part of the rainwater flowing down from the rain cover 18. The bottom end of the rain cover 18 is a detachable base, and the gap is sealed with waterproof glue. A drainage hole is opened at the lowest point of the lower edge of the waterproof cover to allow rainwater flowing into the waterproof cover to be quickly discharged.

[0091] The diameter of the water blocking cap 19 is between the inner diameter of the bottle mouth and the inner diameter of the rain cover 18. The connection between the water blocking cap 19 and the rainproof insulating connecting tube 17 is sealed with waterproof glue to prevent rainwater from penetrating into the rainproof insulating connecting tube 17 inside the water blocking cap 19 along the rainproof insulating connecting tube 17.

[0092] The internal support screw rod near the bottle mouth strengthens the stability of the rain cover 18, and the connection with the rain cover 18 is sealed with waterproof glue. The support screw rod at the lower half of the rain cover 18 needs to be equipped with an additional rain cup to prevent rain from wetting the inside of the rainproof insulation cup and maintain insulation. All materials of the rainproof insulation cylinder are made of plastic materials with good insulation, good rigidity and toughness, and good weather resistance. For example, PVC polyvinyl chloride material. The insulation cylinder also reserves wire holes for convenient wires with insulating sheaths to pass through. The wires are connected to the collector wheel 8 and the knife holder 10 to guide the current into the electrical equipment in the car.

[0093] Preferably, the drainage assembly comprises three insulating barrier bars 3;

[0094] Three insulating barrier bars 3 are vertically spaced apart and distributed on the insulating liner 1;

[0095] Two insulating barrier bars 3 are arranged between the two power supply boards 2, and one insulating barrier bar 3 is arranged below the lower power supply board 2;

[0096] The thickness of the insulating barrier bar 3 is greater than that of the power supply board 2, and it is protruding from the power supply board 2. The insulating barrier bar 3 is hollow inside, and a short drainage pipe 25 connected to the inside is fixedly connected to its top surface. A drainage hole 24 connected to the insulating barrier bar 3 is opened on the insulating lining 1.

[0097] The cross-sectional shape is a horizontally placed hollow tower, with high and low barrier ribs on the outside, a slope that is low outside and high inside, and a short tube extending from the drainage hole. Use plastic materials with good insulation, elasticity, and good weather resistance, such as PVC polyvinyl chloride extruded wire. The multiple high and low barrier ribs of the tower-shaped barrier bar make it difficult for the current to cross, and even on rainy days, it can still prevent the lower half of the barrier ribs from being wetted by rain, thereby maintaining good insulation; the short tube extending from the drainage hole guides the water flow downward to keep the top of the cavity from being soaked, thereby blocking the current; the slope that is high inside and low outside can quickly drain the accumulated water in the cavity. Before installation, drill multiple holes at intervals in the upper groove of the barrier bar, insert the short tube into the drainage hole, and the lower edge of the short tube exceeds the cavity wall, and use waterproof glue to seal the gap between the short tube and the cavity wall. The barrier bars are installed at the lower edge of the positive and negative power supply boards 2, and the connection is sealed with waterproof glue. The bottom of the barrier bar is fixed to the insulating lining 1 with insulating plastic steel screws and sealed with waterproof glue. Then, the lining and the bottom of the tower-shaped insulation are pierced to open a drainage hole 24, and the drainage pipe is connected to drain the accumulated water. The insulating barrier bar 3 protrudes from the plane of the power supply board 2. When the vehicle accidentally hits the curb, the vehicle body cannot contact the positive and negative power supply boards 2 at the same time, so the vehicle body cannot form a current loop, avoiding damage to the vehicle body by the current. The tower-shaped hollow structure and elastic plastic material can buffer the accidental impact of the vehicle on the curb power supply facilities, while reducing damage to the vehicle. When raindrops fall on the power supply board 2, they will flow down along the power supply board 2 to the groove of the barrier bar, and fall from the short tube at the opening to the inside of the tower-shaped barrier bar, and then be discharged from the drainage hole 24 at the bottom of the tower along the internal slope, which can keep the top of the cavity from being soaked by rainwater.

[0098] Preferably, it also includes a water flow disperser 41;

[0099] The water flow disperser 41 is connected to the drainage hole 24 through a water pipe and is located above the ground.

[0100] Preferably, the water flow disperser 41 includes a tank body 26, an insulating rod 29, and a rainproof cup 28;

[0101] The tank body 26 is connected to the water pipe, and a plurality of small holes 27 are provided on the outer peripheral wall of the tank body 26 to communicate with the interior thereof;

[0102] The insulating rod 29 is fixedly connected to the bottom of the tank 26 to support the tank 26 above the ground;

[0103] The rainproof cover cup 28 is fixedly connected to the bottom of the tank body 26 and is located on the outer circle of the insulating rod 29 .

[0104] The drainage hole 24 at the bottom of the tower-shaped insulating barrier bar 3 is connected to a water pipe, and the connection is sealed. The water pipe is then connected to a water flow disperser 41 to disperse the water flow into small water droplets, thereby avoiding leakage caused by continuous water flow and providing an additional layer of insulation protection. The straight-cylinder water flow disperser 41 is composed of a tank body 26, a built-in cavity, a rain cover cup 28, and an insulating rod 29, and is made of insulating plastic materials such as PVC polyvinyl chloride materials. The tank body 26 has a larger diameter and can be covered with more small holes 27 to spread the accumulated water. The built-in cavity can raise the water level in the tank body 26, allowing the accumulated water to be discharged faster through more drainage holes. The rain cover cup 28 can prevent the inside of the cup from being wetted by rainwater, thereby maintaining insulation performance. The insulating rod 29 keeps the rain cover cup 28 away from the ground and supports the tank body 26.

[0105] Preferably, the waterproof assembly includes two protective beams 42 and an insulating rain cover;

[0106] The two protection beams 42 are both connected to the insulating liner 1, and the two protection beams 42 are respectively located above the upper power supply board 2 and below the lowest insulating barrier bar 3, and the top surface of the upper protection beam 42 protrudes from the top surface of the insulating liner 1;

[0107] The insulating rain cover is L-shaped, fixedly connected to the insulating liner 1 and the upper protective beam 42, and is inclined, with the lower edge of the insulating rain cover shielding the upper protective beam 42.

[0108] Located at the upper and lower ends of the power supply board 2, protruding from the plane of the power supply board 2, and forming a semi-open gap with the insulating barrier bar 3 and the power supply board 2. The anti-collision beam uses a rigid and insulating material, such as plastic steel wire. The height of the anti-collision beam perpendicular to the power supply board is not less than the tower-shaped barrier bar, and is less than the protruding edge of the road guardrail 34, so as to reduce the accidental collision of the vehicle with the power supply wall.

[0109] The vertical width of the notch is smaller than the length, width and height of the vehicle. When the vehicle body accidentally hits the power supply wall, it first hits the insulating anti-collision beam or the insulating barrier bar 3, thereby protecting the power supply board 2 and ensuring that the vehicle body will not contact the positive and negative power supply boards 2 at the same time to form a loop, causing secondary damage to the vehicle or personnel.

[0110] The cross-section of the rain cover is L-shaped, and the lower edge of the rain cover covers the upper anti-collision beam to prevent the upper protection beam 42 from getting wet and causing leakage on rainy days. The rain cover is made of insulating and weather-resistant plastic materials, such as PVC polyvinyl chloride materials. An insulating and waterproof rain cover is installed on the upper anti-collision beam. The rain cover is higher on the right and lower on the left, and rainwater is discharged to the outside of the road, which can reduce rainwater dripping on the power supply board 2. The outer edge of the rain cover is close to but does not exceed the outer edge of the highway guardrail 34, so as not to affect the passage of vehicles; the lower edge of the rain cover and the upper power supply board 2 maintain a certain vertical distance, so as not to affect the movement of the collector wheel 8 and the collector pole.

[0111] The upper end of the column is also fixedly connected to a main rain shield 45. The main rain shield 45 above the power supply wall has a large width, which can shield the top of the power supply wall and prevent most of the rain from splashing on the power supply wall. The height of the main rain shield 45 is not lower than the height limit of the lane and does not affect the passage of vehicles. The transverse cross-section of the main rain shield is an L-shaped slope design to prevent the downstream rainwater from soaking the inside of the rain shield.

[0112] Preferably, it also includes an electric push rod 39 arranged on the vehicle, and a distance limiting wheel rotatably connected to the movable end of the electric push rod 39, the number of the electric push rod 39 is two groups, and the two groups of electric push rods 39 are respectively arranged at the front and rear of the vehicle.

[0113] Preferably, if Fig.10 As shown, it also includes a cylinder solenoid valve 44 (the cylinder solenoid valve 44 includes a solenoid coil), an electromagnet 43, two bottom switches 36, an iron block 37, an electric push rod 39, and a right turn signal switch 40 of the vehicle;

[0114] The right turn signal 40 switch of the vehicle is connected in series with the right turn signal 40 of the vehicle, and the other end of the right turn signal 40 switch is connected in series with the electromagnet 43, the other end of the right turn signal 40 is connected to the negative pole of the power supply, and the other end of the electromagnet 43 is connected to the positive pole of the power supply. The iron block 37 is fixedly connected to the bottom switch 36, and the electromagnet 43 is arranged on one side of the iron block 37 of the two bottom switches 36, one end of one of the bottom switches 36 is connected to the negative pole of the power supply, and the other end is connected to the cylinder solenoid valve 44 and then connected to the positive pole of the power supply, while one end of the other bottom switch 36 is connected to the positive pole of the power supply, and the other end is connected to the electric push rod 39 and then connected to the negative pole of the power supply. At the same time, a self-resetting spring 38 is arranged on the bottom switch 36 to drive it to self-reset.

[0115] The limited distance wheel can be integrated and fixed on the electric push rod 39 which can reciprocate laterally. The electric push rod 39 requires a built-in limiter, which can stop automatically at the top and bottom, and has a switch function of one-key end mode and one-key bottom mode. The electric push rod 39 bottom switch 36 and the vehicle right turn signal 40 switch can be connected through an electromagnet 43.

[0116] like Fig.11As shown, the elastic wheel protruding from the side of the vehicle body can rotate and slide horizontally along the vertical plane track, so that the vehicle body and the guardrail 34 can always maintain a certain safe distance when the vehicle moves to prevent the vehicle body from scratching the guardrail 34. The limited distance tire adopts a flexible material, such as a rubber material, which is conducive to reducing the noise of the limited distance wheel running on the plane of the guardrail 34 track, and is also conducive to reducing the impact force of the vehicle near the plane of the guardrail 34 track during movement. The vertical distance between the outermost edge of the front limited distance wheel and the vehicle body is slightly shorter than the vertical distance between the outermost edge of the rear limited distance wheel and the vehicle body. The line connecting the two points and the center line of the vehicle form a small angle, which is equivalent to the direction of driving to the left. When the vehicle moves in a straight line close to the guardrail 34 track, the driving force F1 coincides with the direction of the center line of the vehicle body and the resistance F2 is parallel to the guardrail 34 track. The common starting point of the force is the center point of the object, and the force analysis of the horizontal direction of the vehicle body is carried out. According to the parallelogram rule, the adjacent sides of the two forces are used to form a parallelogram, and the resultant force is the diagonal, which is the same as the starting point of the component force. This forms a leftward pressure F3 perpendicular to the guardrail 34. According to Newton's third law, the guardrail 34 also generates an equal and opposite force (rightward support force) F4 on the vehicle body, and the force acts on the same straight line. The rightward support force F4 and the vehicle driving force F1 have the same starting point but different directions. According to the parallelogram law, the adjacent sides of the two forces are used to form a parallelogram. The resultant force is the diagonal line, which forms a forward force F5 parallel to the guardrail 34 at the same starting point as the component force, so that the vehicle can run close to the track plane of the guardrail 34. When moving on a right curve, the vehicle body will be subjected to an additional leftward centrifugal force perpendicular to the plane of the guardrail 34, and the vertical pressure of the vehicle body on the track plane of the guardrail 34 will increase. According to Newton's third law, the guardrail 34 also generates an equal and opposite force (rightward support force) on the vehicle body, and the force acts on the same straight line. The vehicle can still run close to the track plane of the guardrail 34. When the vehicle moves in a left curve, the vehicle body will be subjected to a centrifugal force perpendicular to the plane of the guardrail 34 to the right. When the centrifugal force is greater than F3 and the vehicle body is about to move to the right, the tire will generate a friction force of equal magnitude and opposite direction to maintain balance, so that the vehicle can still run close to the track of the guardrail 34 at a limited speed. The moving vehicle body and the power supply board 2 maintain a relatively close and stable distance, reducing the length and wind resistance of the collector rod, so that the collector wheel 8 can stably maintain electrical contact with the power supply board 2 and obtain stable electrical energy.

[0117] The distance limiting wheel can be fixed on the head of the electric push rod 39 which can reciprocate laterally. The electric push rod 39 requires a built-in limiter, which can stop automatically when it reaches the top or the bottom, and has a switch function of one-key top and one-key bottom mode. The electric push rod bottom switch 36 and the vehicle right turn signal 40 switch can be connected through an electromagnet 43.

[0118] When the electric vehicle enters the power supply lane, the driver turns on the top switch of the electric push rod 39 of the limited distance wheel, the limited distance wheel protrudes out of the vehicle body, the vehicle slightly deviates to the left and drives along the track plane of the guardrail 34, and the vehicle body and the power supply board 2 maintain a short and stable distance; the driver then presses the top switch of the collector wheel 8, the positive and negative collector wheels 8 protrude out of the vehicle body, and the power supply can be started after they contact the power supply board 2 at the same time, realizing stable power supply during movement. When the electric vehicle needs to change lanes, the driver can first observe the vehicle condition behind the right, and then turn on the right turn signal 40 switch, the collector wheel 8 and the limited distance wheel switch will also retract into the vehicle body in conjunction with the right turn signal 40, and the vehicle is driven by the stored electric energy to change lanes.

[0119] Preferably, it also includes columns and guardrails 34 , the insulating liner 1 is fixedly connected above the ground through the columns, and the guardrails 34 are arranged on the ground and located in front of the insulating liner 1 .

[0120] The technical effects brought by the present invention are:

[0121] 1. The positive and negative power supply plates 2 are designed perpendicular to the side of the road, and cooperate with the horizontally rotatable collector wheel 8, which can roll and slide on the rigid track plane and maintain electrical contact. The collector wheel 8 can slide away from the power supply plate 2 at any time, or it can approach and contact the power supply plate 2 during driving. It avoids the situation where the pantograph and other collectors are entangled or stuck by the power supply wire grid, thereby improving safety. The working current maintains a sufficient vertical safety distance from the road surface to prevent leakage problems caused by the wet road surface, and safety is guaranteed. Compared with the existing trolleybus solution, the vertical power supply track plane on the road side has small restrictions on the size and height of the vehicle body, and can be compatible with the power supply of small and large vehicles, with good versatility.

[0122] 2. The power supply side wall has a double concave design, and the positive and negative power supply boards 2 are embedded in the concave notch. There are rigid protective beams 42 at the upper and lower ends of the notch, and there are insulating barrier strips between the positive and negative power supply boards 2 protruding from the plane of the power supply board 2. The vertical height of the notch is less than the length, width or height of the vehicle. When the vehicle accidentally touches the curb power supply device, it can prevent the vehicle body from contacting the positive and negative power supply boards 2 at the same time, avoiding the formation of a current loop on the vehicle body, thereby improving safety. The design of the power supply wall has a low facility height, and is less difficult to install, inspect and maintain, with little impact on road traffic.

[0123] 3. There is a dump switch at the connection between the power supply board 2 and the power supply cable. When the power supply board 2 is knocked down by a vehicle, it can automatically cut off the power supply to avoid secondary damage caused by leakage or short circuit, thus improving safety. The power supply wall adopts a parallel circuit. When the power supply wall of a certain section of the road is accidentally interrupted, it will not affect the power supply of the power supply wall of the section without the accident. This improves practicality.

[0124] 4. The tower-shaped insulating barrier bar 3 has barrier ribs of different sizes on the outside, a hollow cavity and a downward-extending drainage short pipe 25 on the inside, which not only maintains the insulation between the power supply board 2 and the upper and lower adjacent objects, but also realizes the drainage of accumulated water and keeps the top of the cavity dry, achieving good insulation; the hollow structure and elastic material can also buffer accidental collisions of vehicles.

[0125] 5. The design of the plane track of the guardrail 34 perpendicular to the side of the road and the front and rear elastic limited-distance wheels protruding from the side of the vehicle body can make the limited-distance wheels rotate and slide smoothly on the plane track of the guardrail 34, so that the minimum vertical distance between the vehicle body and the guardrail 34 can be kept fixed, avoiding the vehicle body from being scratched by the guardrail 34 and improving safety.

[0126] 6. The design of the detachable hub structure of the collector wheel 8 and the screw safety line hole reduces the weight of the collector wheel 8, realizes the detachable replacement of wearing parts, and maintains good anti-loosening performance.

[0127] 7. The blade holder 10 structure of a single-row roller skate can be configured with multiple collector wheels 8 to reduce contact resistance and help reduce the vertical space occupied by the power supply board 2.

[0128] 8. The design of the elastic reset ring on the connecting rod 9 can automatically keep the tool holder 10 and the connecting rod 9 vertical when the collector wheel 8 does not contact the power supply board 2, so that the collector wheel 8 can maintain a good contact preparation posture when it slides close to the power supply board 2.

[0129] 9. The design of the elastic telescopic rod 22 with a spring and the movable shaft of the connecting rod 9 applies spring tension to the tool holder 10 regardless of driving on a straight road or a curved road, so that the tool holder 10 remains parallel to the track plane of the power supply board 2.

[0130] 10. The insulating connector with the can-shaped rain cover 18, the water blocking cap 19 and the rain cover cup 28 can maintain good insulation in windy and rainy weather, thereby better protecting personnel and equipment and improving safety.

[0131] 11. The water flow disperser 41 can disperse the continuous water flow into fine water droplets, reducing the risk of leakage. The water flow disperser 41 with a cavity design can improve the efficiency of water flow dispersion. The design with a rain cover cup 28 and a support rod can keep the disperser well insulated from the wet ground, thereby better protecting personnel and equipment and improving safety.

[0132] 12. The design of the vertical distance from the outer edge of the limited wheel to the vehicle body is short in the front and long in the back, so that the direction of the moving vehicle is slightly biased to the left, forming a leftward pressure on the guardrail 34, so that the vehicle runs close to the track plane of the guardrail 34, and the vehicle body and the power supply board 2 maintain a short and stable distance, thereby ensuring the stability of power supply.

[0133] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
