Definitions

  • Curb or kerb charging device for charging an energy storage device of an electrically powered vehicle
  • the invention relates to a curbstone or kerbstone charging device for charging an energy storage device of an electrically powered vehicle with a base body which is made of one or more of the materials concrete, natural stone, plastic and composite material and has a receiving space which is delimited by two side walls delimiting the base body in the longitudinal direction, a front wall extending in the longitudinal direction and a rear wall extending in the longitudinal direction and a base of the base body, a closure cover which covers an upper side of the receiving space and areas of an upper side of the side walls of the base body, an upper side of the front wall and an upper side of the rear wall adjacent to the upper side of the receiving space, and a charging unit which is arranged in the receiving space.
  • curb charging devices are charging stations integrated into the curb to which vehicles can be connected via an electrical connection in order to charge their energy storage units or batteries. This particularly applies to purely electrically powered vehicles but also to hybrid vehicles. Vehicles that can be charged can be passenger cars, trucks, motorcycles or electric bicycles.
  • DE 10 2017 218 947 A1 proposes arranging a charging device for charging vehicles in the curb of a road boundary.
  • the curb is either designed with an energy supply or has its own energy storage unit.
  • a special design of such a curbstone with electronics for charging a vehicle is known from GB 2 592 186 A.
  • This curbstone is modular and has a base element into which a receptacle can be used which can be replaced and is therefore not attached.
  • the components for electrically charging a vehicle battery are arranged in this container.
  • the receptacle is open at the top and is closed by a lid which limits the base element towards the street with a sloping wall.
  • the base element as well as the container and the lid are made of plastic.
  • GB 232332 A discloses a combined gutter and curbstone with a cavity in which electrical cables are arranged and which is closed at the top by a cover.
  • the front wall and rear wall bordering the cavity are reinforced by metal rods inserted into the concrete.
  • the cover rests on shoulders of the front wall and rear wall. When the front wall is loaded, its thinnest area is loaded against the cover, which in turn is pushed against the thin section of the rear wall, so that there is a risk of the front wall and rear wall breaking in the upper area.
  • the task is therefore to provide a curb or kerb charging device for charging an energy storage device of an electrically powered vehicle, which has a high durability and can therefore be used in large quantities as a curb in cities, but also in car parks or motorway service stations, without the need for constant maintenance or frequent replacement.
  • the electronics in the receiving space should be protected from damage and the curb itself should continue to function as a road barrier, with no damage and consequently no damage to car tires caused by parts of the curb breaking off. It should be possible to manufacture such a curb as inexpensively as possible.
  • the curb should be as flexible as possible and installation should be as simple and error-free as possible.
  • the curb or kerb charging device should be easy to retrofit in prepared streets.
  • the electronics should be easy to remove for maintenance and comply with existing standards. Furthermore, a high level of tightness against the ingress of water and dirt should be achieved.
  • a curb or kerb charging device for charging an energy storage device of an electrically powered vehicle with the features of the main claim 1.
  • UHPC ultra-high-strength concrete
  • a receiving space is formed inside the base body.
  • the base body has at least two side walls delimiting the base body in the longitudinal direction, one in The base body has a front wall extending in the longitudinal direction, the outer wall surface of which, when installed, laterally delimits a driveway, a rear wall extending in the longitudinal direction, and a floor. If the base body is used as a curb, it can, for example, delimit a parking space to the front. If used as a kerb, the front wall extends parallel to the road and delimits it, while the rear wall rests against the paving stones of the sidewalk or the asphalt of a cycle path, for example, while the ends of the side walls each rest against an adjacent curb. Please note that in this context, the front wall and the rear wall only refer to part of the rear or front wall, while the side walls extend over the entire depth of the curb and thus form part of the front surface or rear surface of the curb.
  • the base body is open at the top and is closed by a closure cover, which is made in particular from metal or a fiber-reinforced plastic, so that this is arranged on the upper side of the receiving space. It also covers areas adjacent to the upper side of the receiving space, an upper side of the side walls, an upper side of the front wall and an upper side of the rear wall.
  • This four-sided support of the closure cover means that loads from vehicle tires, for example, can be absorbed and evenly distributed into all walls of the curb or kerb. This creates a curb or kerbstone charging device with high strength, since even forces introduced over small areas can always be dissipated in the curb over several areas connected to the foundation.
  • the cover can have windows or openings, for example to make an energy meter display visible or to make a charging socket accessible.
  • a charging unit is arranged in the receiving space.
  • a charging unit is understood to mean either just a charging socket or an inductive charger or a completely self-sufficient charging unit that only requires a power connection and contains all electronic components.
  • individual electronic components of the charging unit such as an energy meter, a charging controller or similar, can also be arranged in the receiving space.
  • a charging unit is understood to mean any individual component or several components that can be used to charge the energy storage device of the electric vehicle or hybrid vehicle.
  • the front wall of the curb or kerbstone loading device is firmly connected to the rear wall via at least one force transmission element.
  • the support of the closure cover prevents overloading of the edge areas of the curb adjacent to the closure cover. Instead, a force acting on the front wall can be diverted or partially absorbed via the rear wall through the fixed connection to the rear wall. It is important to provide a rigid connection in order to be able to divert any bending force immediately.
  • top, bottom, front wall, rear wall, top, floor, side walls and the like always refer to the curb or kerbstone in its installed state on the road with its corresponding orientation and direction of view from the road.
  • reinforcing bars are cast into the base body. These are mainly made of steel and serve to increase the strength and stability of the base body.
  • reinforcing bars are U-shaped and extend from the front wall in a first 90° arc into the ground and over a second 90° arc into the rear wall. In this way, the rigidity and tensile strength of the base body is increased.
  • the U-shape allows forces to be diverted in particular towards the ground and thus to the foundation.
  • a plurality of reinforcing bars extending in the longitudinal direction of the base body are preferably arranged in the base body, which also absorb bending stresses and resulting tensile forces on the rear side of the front wall.
  • two of the longitudinally extending reinforcing bars are arranged in the area of the arches of the U-shaped reinforcing bars and are attached to the U-shaped reinforcing bars, and one of the longitudinally extending reinforcing bars is arranged in an upper quarter of the front wall and the rear wall and is attached to the legs of the U-shaped reinforcing bars.
  • the U-shaped reinforcing bars are thus fixed in their position relative to one another both in the area of their arches and in the upper area by the reinforcing bars extending along the curb, and a closed Grids are created. This reliably absorbs forces acting in different directions in the concrete, thus increasing the durability of the base body.
  • the structure of the reinforcing bars is easy to manufacture and is stable in itself, so that it can be placed as a whole in the mold for the casting.
  • the front wall and the rear wall in the area surrounding the legs of the U-shaped reinforcing bars have a greater wall thickness than in the other areas. This means that the walls that delimit the receiving space can be made very strong with less material. If the bars running in the longitudinal direction extend into the side walls, forces acting via the front wall can also be diverted to the side walls.
  • the closure cover serves as a force transmission element and is firmly attached to the front wall and the rear wall via a screw fastening. Due to this firm connection of the closure cover to both the front wall and the rear wall, forces acting on the front wall are diverted via the cover directly towards the rear wall, which, when installed, rests firmly against the path behind it, so that forces can be diverted to the rear and into the ground or foundation. This connection also reduces tensile stresses, which would occur primarily in the upper area of the rear side of the front wall, since deformation of the front wall is largely reduced by the firm connection via the protective cover. The durability of such a curbstone is therefore significantly increased.
  • the cover serves as a force transmission element and is positively attached to the front wall and the rear wall. This can be done using positioning pins, for example.
  • the screw connection then follows, for example, via the side walls. This means fewer screws are required, so that assembly is also quicker. A preload can also be created against the expected forces.
  • the reinforcement rods protrude from the tops of the rear wall and the front wall and have an external thread on their ends protruding from the base body, to which the closure cover is attached using screw nuts.
  • the force is transmitted between the front wall and the rear wall directly via the reinforcement, which relieves the load on the concrete or plastic walls.
  • the structure is significantly simplified because no further components, such as additional threaded rods, have to be cast around. The costs for producing the curb or kerbstone loading device are reduced accordingly.
  • threaded bolts or sleeves are attached to the front and rear walls, via which the cover is attached to the base body.
  • the steel reinforcement can be dispensed with if necessary and the frictional connection between the front and rear walls can still be established by the frictional connection.
  • the threaded bolts or sleeves are cast into the base body. This allows a firm connection to be made without additional adhesive.
  • the threaded bolts with their external thread protrude from the top of the front wall and the rear wall. This makes it easier to align the cover, which can be placed on the threaded bolts with its corresponding holes and easily screwed on from above.
  • the cover cap rests on the outer circumference with a circumferential profile seal on the top of the front wall, the rear wall and the side walls, and in an area further inward from the profile seal, the cover cap rests on raised areas that are formed on the top of the front wall and the rear wall.
  • the profile seal protects the receiving space from the ingress of water or dirt and is compressed when the nuts are tightened, so that tolerance compensation is achieved and the cover cap always has a circumferential support surface for force transmission.
  • the closure cover and the screw fastening are covered by an outer cover that forms an extension of the walkway.
  • the closure cover only has to transfer the forces to be transferred from the front wall to the rear wall, while the outer cover can absorb vertical forces in particular and divert them to the side walls, the front wall and the rear wall and to the floor.
  • the outer cover When installed, the outer cover preferably completely covers the edges between the top and the outward-facing wall surface of the front wall and the outward-facing wall surface and the top of the rear wall. These edges are thus protected from the introduction of larger forces over a small area, for example due to the impact of a vehicle tire.
  • the outer cover is attached to the closure cover with an intermediate cover in between.
  • the intermediate cover which can be designed as a reinforcing plate, rests with its underside against the closure cover and its upper side against the outer cover. This significantly increases the rigidity of the overall construction and prevents forces from occurring on the outer cover that would lead to major deformation of the outer cover, which means that it can be made significantly thinner.
  • the cover has two internal threads, through which the outer cover is attached to the cover using screws, with the intermediate cover in between. This means that the intermediate cover and the outer cover can be positioned and attached to the cover together using just two screws.
  • the base body has a first rear wall section which extends from the bottom of the base body over a third to three quarters of the height of the base body upwards in the direction of the closure cover with a thicker wall thickness than in the second rear wall section adjoining it at the top.
  • This first rear wall section then extends to under the sidewalk. In this way, an even greater stability of the rear wall for the discharge occurring forces in the surrounding soil or foundation.
  • the force transmission element is formed by partition walls of the base body, which extend in the receiving space from the front wall to the rear wall. This improves the rigidity and thus durability of the front wall, since it is supported by the partition walls to the rear wall, so that here too a force transmission to the rear wall takes place.
  • the partition walls preferably end below the top sides of the front wall and the rear wall, whereby at least existing cabling can continue to be carried out within the receiving space between the individual spaces created by the partition walls if parts of the loading unit are arranged in these.
  • the partition walls advantageously extend between the two legs of a U-shaped reinforcing bar, so that no additional thickenings have to be made on the front wall and the rear wall, which would further restrict the installation space.
  • the thickness of the front wall and the rear wall can therefore be chosen to be relatively small.
  • the closure cover has an outer surface that forms the walkway and is attached to the base body via internally threaded bolts embedded in the area of the side walls, so that the multi-part cover can be dispensed with.
  • curb or kerb charging device for charging an energy storage device of an electrically powered vehicle, which offers high strength and durability with reduced Costs, which avoids damage to the curbs and kerbs and at the same time protects the electronics of the charging unit.
  • the curb or kerb charging devices according to the invention are flexible and modular and yet very easy to install. The necessary excavation work for installation is minimized, as is the number of assembly steps to implement a system that can be used, for example, to build a smart city with networks, charging stations, counting and measuring systems. The cityscape is not changed. Loss of space is avoided, as are tripping hazards caused by cables on the sidewalks.

  • Figure 2 shows a base body 34 of a curbstone or kerbstone loading device 18. This consists of concrete or a plastic that can contain fiber reinforcements.
  • This base body 34 has a base 36 from which a total of two side walls 38, a front wall 40 and a rear wall 42 extend upwards.
  • the side walls 38 are located at the two ends of the curbstone or kerbstone loading device 18, viewed in the longitudinal direction, so that neighboring curbstone or kerbstone loading devices 18 rest against one another with these side walls 38.
  • the front wall 40 delimits the curbstone or kerbstone loading device 18 towards the street.

  • the power supply cable 22 protrudes through an opening (not shown) in the base 36 of the base body 34 into the receiving space 46, which can simultaneously serve as a drain opening for draining off water accumulating in the receiving space 46.
  • the receiving space 46 is delimited downwards and to the sides by an inner wall surface 50 of the front wall 40, the floor 36 and inner wall surfaces 52 of the side walls 38.

  • Two further reinforcing bars 58 are arranged close to the upper sides 60, 70 in the longitudinal direction. These rest against the legs 68 of the U-shaped reinforcing bars 54 from the outside and are also connected to them.
  • the reinforcement bars 54, 56, 58 each have a distance from the outer surfaces of the surrounding concrete that corresponds to the diameter of the reinforcement bars 54, 56, 58. Accordingly, the distance of the reinforcing bars 58 to the top side 60 of the front wall 40 and to the top side 70 of the rear wall 42 is selected such that it corresponds approximately to the diameter of the reinforcing bar 58. Since the front wall 40 and the rear wall 42 are to be made as thin as possible in order to be able to provide sufficient space to accommodate a loading unit 48 in the receiving space 46, an area 74 surrounding the legs 68 of the U-shaped reinforcing bars 54 is made thicker so that semicircular ribs 76 protrude into the receiving space 46.
  • elevations 80 are formed on inner regions of the upper sides 60, 70 of the rear wall 42, the front wall 40 and the upper sides 78 of the side walls 38 adjacent to the receiving space 46, as well as on the regions surrounding the legs 68.

  • the closure cover 82 serves as a force transmission element 90, via which forces acting on the front wall 40 can be diverted to the rear wall 42 through the fixed connection of the closure cover 82 to both the front wall 40 and the rear wall 42. Since this is a rigid connection, tensile forces in particular that could otherwise occur on the inner wall surface 50 are also absorbed, since bending of the front wall 40 is largely excluded.
  • the closure cover 82 can be made, for example, from a punched and formed sheet steel of approximately 3 mm thickness and can have corresponding embossings to increase stability. Viewed in the longitudinal direction, two internal threads 92 are formed in the end sections on the closure cover 82, which can either be designed as a sleeve 93 in an opening or can be introduced directly into the closure cover 82.

However, the ends of the impact wall 98 and the angled wall 106 are vertically spaced from the wall surfaces 44, 108 arranged as an extension of these walls 98, 106. Accordingly, the outer cover 94 does not rest on the front wall 40 or the rear wall 42, but is horizontally displaceable relative to them.
  • the outer cover 94 rests on an intermediate cover 110 designed as a reinforcing sheet, which is clamped between the closure cover 82 and the outer cover 94 and can be made, for example, from an embossed and formed 2 mm steel sheet and can also have deformations or embossings that lead to a stiffening of the sheet.

  • the tensile forces to which the base body is sensitive can be reliably absorbed or their The rigid connection prevents this from occurring.
  • the electronics can be adapted to the respective conditions, in particular the legal conditions of the countries.
  • the charging socket can be equipped with very different lifting, folding or swiveling mechanisms.
  • the fastening of the cover as a force transmission element can also be done via cast-in threaded sleeves in the front wall and the rear wall.
