Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of charging piles, in particular to a mobile electric vehicle charging device and a trajectory control method thereof. BACKGROUND

[0002] At present, the charging device of the electric vehicle is mostly fixed and cannot be moved, so the electric vehicle needs to drive to the appropriate parking space to realize charging. In addition, when all the parking spaces of the charging piles are occupied, due to the length limitation of the charging gun and the space limitation of the parking space, some vehicles are difficult to charge.

[0003] The mobile electric vehicle charging device in the prior art usually includes the following three types: mobile charging robot, portable charging device and mobile charging pile.

[0004] 1. Mobile charging robot: through L4 level and above automatic driving technology, high-precision navigation and intelligent scheduling system, the robot can autonomously plan the path and avoid obstacles, without manual driving or guiding, and can realize 24-hour uninterrupted service. However, the maturity of the automatic driving technology needs to be improved, the adaptability to complex scenes is limited, it depends on the infrastructure and network support, and the hardware cost is high, such as the laser radar required for automatic driving.

[0005] 2. Portable charging device: similar to the mobile power supply of mobile phone, it is usually applied to outdoor power supply, emergency power supply and other scenes, needs to be transported by other vehicles, and is mainly used as an emergency power supply measure when the power is out on the way. However, due to the capacity and weight limitation, the greater the power and capacity, the higher the weight of the device, resulting in the decrease of portability.

[0006] 3. Mobile charging pile: the charging device is flexibly moved through the fixed guide rail, but the mechanical parts such as guide rail slider and driving motor of the mobile trolley are easily jammed or worn due to dust and oil accumulation caused by long-term high-frequency sliding, and need to be regularly maintained (such as cleaning the guide rail and lubricating the parts every month), increasing the operation and maintenance cost.

[0007] The prior art such as Chinese patent "CN212422870U" provides a movable parking space electric vehicle charging device, which comprises a slide rail, a plurality of charging piles, the slide rail comprises a straight rail and a plurality of arc-shaped rails, the upper surface of the straight rail is provided with a first sliding groove, the upper surface of the arc-shaped rail is provided with a second sliding groove, and the lower surface of the base of the charging pile is provided with a bearing. When one charging pile is arranged on the straight rail between the two ends of the arc-shaped rail, the remaining charging piles can slide along the arc-shaped rail. The utility model has the following advantages and effects: the slide rail is arranged behind a plurality of continuous parking spaces, and the number of charging piles arranged on the slide rail is less than the number of parking spaces. When the electric vehicle needs to use the charging pile, the charging pile can move along the straight rail and the arc-shaped rail of the slide rail through the bearing, so that any charging pile can be moved to any parking space, thereby saving the number of charging piles required to be arranged and meeting the charging of the electric vehicle.

[0008] In the scheme, the charging equipment is flexibly moved through the fixed guide rail, the charging equipment can only move along the guide rail, cannot serve across the guide rail area, if the parking lot is dispersedly arranged, the parking spaces are not arranged in a straight line (such as arc-shaped parking spaces, irregular partitions), it is difficult to cover all the parking spaces, the flexibility is lower than that of the vehicle-mounted mobile charging pile, and the guide rail slider, the driving motor and other mechanical parts of the mobile trolley are long-term high-frequency sliding, are easy to be stuck or worn due to dust and oil accumulation, and need to be regularly maintained (such as cleaning the guide rail and lubricating the parts every month), thereby increasing the operation and maintenance cost.

After the charging station is moved to the support rail above the call position on the call panel, slowly bring the power connection port of the trolley above the charging station close to the power connection seat inside the support rail for connection, and then stop moving.

[0026] The beneficial effects are:

[0027] I. This invention, by setting up a track contact rail, ensures that when the pulleys under the trolley roll forward, the rotation of the two sets of drive wheels drives the tracks to roll. The track in the direction of the trolley's forward movement, when the oil replenishment roller rotates, has oil grooves on its surface that carry some lubricating oil to wet the oil-absorbing layer on the track surface. By setting two sets of tracks, one in front for applying lubricating oil and the other behind for wiping and absorbing lubricating oil, lubricating oil is always present on the path of the pulley along the rail, while avoiding the situation of large areas of lubricating oil being applied to the rail itself. This avoids the time-consuming and labor-intensive process of applying lubricating oil to the entire path of the pulley during conventional rail lubrication, and also avoids the problem of accelerated oxidation and shortened service life of lubricating oil due to large-area exposure to air during conventional rail lubrication.

[0028] Secondly, the oil cavity is provided with pressing rollers on both sides for extruding the oil absorption layer on the surface of the track, so that the dirty oil absorbed by the oil absorption layer can be extruded when the track rotates, the track in front can be continuously coated with relatively clean lubricating oil, and the track in the rear can be kept in a relatively dry state, so that the effect of subsequent wiping and absorbing lubricating oil is ensured.

[0029] Thirdly, the lubricating oil is added in the mode that the rotation of the oil supplement roller switches the oil groove, so that the amount of lubricating oil added each time is constant, the problems of waste caused by excessive lubricating oil and insufficient lubrication caused by too little lubricating oil do not occur, and after the rotation of the oil supplement roller is stopped, the outer wall of the oil supplement roller is attached to the lubricating box, so that the leakage of lubricating oil is prevented, and the guide scraper provided on both sides of the bottom of the lubricating box can guide the coated lubricating oil when the lubricating box follows the pulley, so that the lubricating oil is prevented from spreading to both sides of the pulley and beyond the effective range of the track when the pulley is pressed.

[0030] Fourthly, the filter plate provided in the oil cavity can intercept some impurities in the lubricating oil when the track is extruded by the pressing roller to return the extruded lubricating oil to the oil cavity, so that the lubricating oil can be recycled, the possibility of scratching the pulley and the slide rail is increased, and the liquid level of the lubricating oil above the filter plate rises when the filter plate is blocked, so that the floating block is lifted by the buoyancy generated by the rising liquid level of the lubricating oil, the rising floating block drives the piston plate to extrude the air in the air box, the extruded air enters the air pipe and pushes the piston block in the air pipe to move, the guide strip connected below the slide rod is slid on the surface of the filter plate under the traction of the magnetic attraction between the piston block and the magnetic block provided in the slide rod, the impurities blocking the filter plate are scraped, the filter plate is dredged, the flow of the lubricating oil through the filter plate is restored, the liquid level of the lubricating oil above the filter plate gradually decreases, the floating block loses the support of the buoyancy of the lubricating oil and sinks due to its own gravity, the air on the inner wall of the air pipe is extracted, the piston block is reset, and the guide strip is reset under the traction of the magnetic attraction between the piston block and the magnetic block provided in the slide rod, so that the purpose of automatic unblocking is achieved.

[0031] Fifthly, when the motor-driven pulley rotates, the first gear rotates to drive the two second gears meshing with the first gear, and when the two second gears rotate, they respectively drive the corresponding drive wheels on one side to rotate through the two synchronous wheels matched with the synchronous belt, so that the rotation of the two drive wheels drives the two tracks on both sides to rotate synchronously in the same direction, and since the first gear drives the oil supplement roller to rotate through the two synchronous wheels matched with the synchronous belt, the overall lubricating action follows the rotation of the pulley, so that the purpose of automatic lubrication is achieved.

DETAILED DESCRIPTION

[0045] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in detail. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0046] Referring to Figure 1 - Figure 11 As shown in the figure, the present application provides a mobile electric vehicle charging device, which comprises a slide rail 1, a plurality of support rails 2 are distributed on the slide rail 1, the specific positions of the support rails 2 should be planned according to the distribution of parking spaces, a plurality of trolleys 5 are slidingly connected in the slide rail 1, and the bottom of each trolley 5 is fixedly connected with a charging pile 3. A support 6 is rotatably connected at the position of each corner of the bottom of the trolley 5, a pulley 7 is rotatably connected to the inner wall of the support 6, the trolley 5 is arranged to drive the charging pile 3 to slide and adjust the position on the slide rail 1, a lubricating box 8 is fixedly connected to the top of the inner wall of the support 6, a lubricating mechanism is arranged in the lubricating box 8, the lubricating mechanism comprises an oil cavity 81, the oil cavity 81 is arranged in the inside of the lubricating box 8, oil channels are arranged on both sides of the lubricating box 8 and communicated with the oil cavity 81, two oil channels are rotatably connected with tracks 82 on the inner wall, and the tracks 82 are driven by two groups of drive wheels 83, and the outer surfaces of the two groups of tracks 82 are provided with an oil absorption layer. An oil groove is arranged on the surface of the oil supplementing roller 84, two pressure rollers 85 are rotatably connected to the inner wall of the oil cavity 81 on both sides, and the outer wall of the pressure roller 85 is in close contact with the track 82. Guide scrapers 10 are fixedly connected to the bottom of the lubricating box 8 on both sides. When the pulley 7 under the trolley 5 rolls forward, the two groups of drive wheels 83 rotate to drive the tracks 82 to roll, and the tracks 82 on one side of the forward direction of the trolley 5 are wetted by the oil absorption layer on the surface of the tracks 82, which is wetted by the oil groove on the surface of the oil supplementing roller 84. The oil absorption layer can be made of modified polyurethane sponge, nitrile rubber sponge and other materials, which has excellent elasticity, wear resistance and oil resistance, and good adsorption effect on mineral oil and vegetable oil. The counterclockwise rotating track 82 will smear the adsorbed lubricating oil on the path rolled by the pulley 7 (for reference Figure 7lubricating oil can buffer the collision and scraping between these small protrusions, reduce the shedding of surface material, and form a protective film to prevent direct metal contact from occurring. The reverse rotation of the track 82 pushes some of the dirt on the slide rail 1 forward or is absorbed by the lubricating oil on the surface of the track 82, preventing it from entering between the pulley 7 and the slide rail 1 and causing unnecessary wear. The other set of tracks 82 behind the forward direction of the trolley 5 also rotates counterclockwise, but the oil absorption layer on the surface of the track 82 is not wetted by the lubricating oil, so that it can absorb and wipe off the lubricating oil on the path during rotation. By setting a set of tracks 82 in front of and behind the pulley 7, the front is used to apply lubricating oil, and the rear is used to wipe and absorb lubricating oil. This way, there is always lubricating oil on the path of the pulley 7 on the slide rail 1, but it does not cause a large area of lubricating oil on the slide rail 1. This avoids the need to fully coat the lubricating oil on the path of the pulley 7 during conventional lubrication of the slide rail 1, which is time-consuming and labor-intensive. It also avoids the problem of conventional lubrication of the slide rail 1, where the lubricating oil is exposed to the air for a long time, which can cause the lubricating oil to oxidize quickly and reduce its service life. The oil chamber 81 on both sides is provided with a pressure roller 85 for extruding the oil absorption layer on the surface of the track 82. This can extrude the dirty oil absorbed by the oil absorption layer on the surface of the track 82 during rotation of the track 82, so that the track 82 in front can continuously apply relatively clean lubricating oil, while the track 82 in the rear can maintain a relatively dry state to ensure the effect of wiping and absorbing lubricating oil. The addition of lubricating oil is achieved by rotating the oil tank with the help of the oil supplement roller 84, so that the amount of lubricating oil added each time is constant, and there is no problem of waste due to excessive lubricating oil or insufficient lubrication. When the oil supplement roller 84 stops rotating, the outer wall of the oil supplement roller 84 is in close contact with the lubricating box 8, which can prevent lubricating oil from leaking. The guide scraper 10 on both sides of the bottom of the lubricating box 8 can guide the lubricating oil during the forward movement of the pulley 7 to prevent the lubricating oil from spreading to the sides of the pulley 7 beyond the range of the track 82 when the pulley 7 is pressed. The inside of the trolley 5 is provided with a steering assembly for controlling the steering of the pulley 7 in the support 6. The steering assembly is composed of a servo motor and a reducer, which is used to change the direction of movement of the trolley 5. The outer wall of the support 6 is fixedly connected with a motor for driving the pulley 7 to rotate. The motor drives the pulley 7 to rotate, enabling the trolley 5 to move in the slide rail 1, thereby moving the charging pile 3 below. The bottom of the track 82 is in contact with the inner wall of the slide rail 1.

By arranging the filter plate 86 in the oil cavity 81, the track 82 is extruded by the press roller 85 to seep out lubricating oil, and when the seeped lubricating oil flows below the filter plate 86, the filter plate 86 can intercept some impurities in the lubricating oil, so that the lubricating oil can be recycled, and the possibility of scratching the pulley 7 and the slide rail 1 is increased.

[0048] Further, please refer to Figure 9 、 Figure 10 The oil cavity 81 is provided with a blockage cleaning assembly above the filter plate 86, the blockage cleaning assembly includes two groups of scraping strips 884, the two groups of scraping strips 884 are respectively attached to the inclined surfaces on both sides of the filter plate 86, and the two ends of the scraping strips 884 slide in the sliding grooves opened in the inner wall of the oil cavity 81. When the scraping strips 884 slide on the surface of the filter plate 86, some impurities intercepted on the surface of the filter plate 86 can be scraped off, so as to avoid that the filter plate 86 is blocked by too much impurities, affecting the flow capacity of the filter plate 86, and causing the circulation of the lubricating oil to be blocked.
