[0001] DESCRIPTION
[0002] Curb, paving stone or kerb charging device for charging an energy storage device of an electrically powered vehicle
[0003] The invention relates to a curb, paving stone or kerb charging device for charging an energy storage device of an electrically driven vehicle, comprising a curb, paving stone or kerb unit which has a base body in which an inner receiving space is formed, and a protective cover which essentially closes the receiving space in the direction of a surface serving as a walking or driving surface, and a charging socket which is accessible during a charging process via an opening in the protective cover.
[0004] Such curb, paving stone, or kerb charging devices are charging stations integrated into the curb, paving stone, or kerb, or curbs, paving stones, or kerbs that have at least one charging socket integrated into them and are connected to a central charging station. An electrical connection to an electrically powered vehicle can be established via the charging sockets to charge its energy storage device or battery. This applies in particular to purely electrically powered vehicles but also to hybrid vehicles. Chargeable vehicles can be passenger cars, trucks, motorcycles, or electric bicycles.
[0005] Due to the new legislation, the growing interest of the population in climate protection and the improved economic viability of electrified vehicles, it is to be expected that the proportion of electric vehicles will increase dramatically, especially in inner-city areas, so that the available charging infrastructure must be expanded significantly. This means that some existing parking spaces or sidewalks must be provided with appropriate charging options in order to ensure individual mobility in the future.
[0006] Known concepts for this include the use of streetlights, additional charging stations, or wall boxes on building walls. All of these concepts require additional space and cause disruption to pedestrians due to the charging cables required.
[0007] For this reason, charging systems have become known in which the charging devices or at least the charging sockets are integrated into the curb or the kerbstone or paving stones forming the sidewalk. In this context, it should be noted that, for the purposes of the invention, a paving stone, curbstone, or kerbstone does not necessarily have to comprise a stone element. This means that the paving stones, curbstones, or kerbstones can also be composed of different materials, such as plastic, in particular fiber-reinforced plastic, or metal, concrete, or plastics containing stones. Different parts made of different materials can also be assembled to form the paving, curbstone, or kerbstone unit.
[0008] Integrating the charging socket or the entire charging unit into the curb has the advantage of eliminating charging stations from obstructing the sidewalk and thus detracting from the visual impact. It also prevents charging cables from protruding across the sidewalk and creating tripping hazards for pedestrians. Instead, it requires no additional space, simply utilizing existing infrastructure. It also prevents damage to the charging infrastructure caused by vehicle accidents.
[0009] The charging ports should be easily accessible for initiating the charging process and also easy to install. Furthermore, damage to the charging ports must be avoided.
[0010] A special design of such a curb with electronics for charging a vehicle is known from GB 2 591 830 A. This curb has a modular design and comprises a base element to which a replaceable curb head can be inserted. This can contain electronic elements and a charging socket. This container integrates, for example, wireless telecommunications technologies and infrastructures, such as Wi-Fi, Bluetooth, or parking sensors or even battery packs. The charging socket is attached to a recess in the replaceable curb head from the outside via a flange.
[0011] The problem with such a design, however, is that although the charging sockets are protected from damage by vehicles driving against the curb by their arrangement in the recess, they can easily be removed from the outside via the fastening flange, so that theft of the charging sockets or accidental release due to external influences cannot be prevented.
[0012] The task therefore arises to provide a curb, paving stone, or kerb charging device for charging an energy storage unit of an electrically powered vehicle, in which the charging socket is protected against unauthorized removal both during and outside of the charging process. Furthermore, the charging socket should be as easy to install on the protective cover as possible, and water penetration into the housing or connector compartment should be prevented. Nevertheless, approved replacement or removal by appropriately trained personnel should be easily possible for easy replacement and testing of the charging device.
[0013] This object is achieved by a curb, paving stone or kerb charging device for charging an energy storage device of an electrically powered vehicle having the features of main claim 1.
[0014] A curbstone, paving stone, or kerbstone charging device according to the invention for charging an energy storage device of an electrically powered vehicle comprises a curbstone, paving stone, or kerbstone unit with a surface that forms a walking or driving surface when installed. This unit can be composed of several assembled individual parts and has at least one base body, which can consist in particular of stone, a plastic such as fiber-reinforced plastic, concrete, and various steel parts or reinforcements, as well as a protective cover that essentially geodetically closes off a receiving space in the base body at the top when installed. In this context, "essentially" means that the protective cover can have openings that are closed by other components or cover parts in order to close off the receiving space at the top.This protective cover faces a surface that forms a sidewalk, a road, or a cycle path and is preferably located at the edge of a road or a parking lot. The surface of the protective cover itself therefore forms part of the driving or walking surface. Inside this curb, paving stone, or kerb unit there is at least one cable for the power supply, but various electronic components can also be located inside the unit, which can therefore also serve as a self-sufficient charging station. The power supply cable protrudes into the receiving space and is connected directly, or with the interposition of other electronic components, to a charging socket. This charging socket is accessible during a charging process via an opening in the protective cover, allowing a plug to be inserted into the charging socket.According to the invention, this charging socket is at least indirectly attached to the protective cover via a fastening section of the charging socket. At least indirectly means that the charging socket can be attached to the protective cover directly or via additional intermediate elements, thereby creating an indirect connection. In any case, this type of attachment allows the charging socket to be either fixed to the protective cover or guided to move relative to the protective cover.
[0015] The charging socket's mounting section is located within a completely enclosed space, both during and outside of charging. Accordingly, the mounting section is not accessible from the outside, either during charging or when not in use. Only authorized personnel who are able to open the protective cover can access the mounting section and remove the charging socket from the protective cover for replacement or testing. Furthermore, water penetration into the area around the charging socket is prevented. The protective cover can be easily attached from the back of the base body before being placed on the base body. Pre-assembly is also easy when using lifting or swiveling charging sockets.Furthermore, by removing the protective cover, the charging socket can be lifted out of the housing, allowing full access to the electronics located within the housing. This allows for easy replacement or retrofitting on the hollow curbs.
[0016] In particular, the charging socket is detachably attached, at least indirectly, to the protective cover, allowing for easy replacement or temporary removal for maintenance. Preferably, the charging socket is located within the receiving space, at least when not in use during charging. Accordingly, the charging socket is not accessible from the outside without prior user authentication, thus preventing potential damage.
[0017] Preferably, the protective cover or an intermediate element fastened to the protective cover has a through-opening into which the charging socket projects from its fastening section, so that the charging socket is accessible from the outside for charging, while the fastening section is arranged on the opposite, inaccessible side.
[0018] In a preferred embodiment, the intermediate element is pivotably or liftably attached to the protective cover and has a cover part that closes the opening in the protective cover when not in use. Thus, after authentication, the charging socket is lifted off the protective cover with the cover part or pivoted toward it. In the resting state, the cover part rests on a circumferential edge of the protective cover and thus closes the opening in the protective cover, preventing water penetration and also preventing access from the outside.
[0019] In a further embodiment, the intermediate element has a socket receiving part connected to the cover part, to which the charging socket is attached via its fastening section and in which a through-opening is formed through which the charging socket protrudes. Accordingly, the entire charging socket is located beneath the protective cover and the cover part outside of the charging process and is lifted above the protective cover before charging. The two parts of the intermediate element serve as walls that define the space and shield the socket.Accordingly, in a supplementary embodiment, the space in which the fastening section of the charging socket is fastened is delimited by the socket receiving part, the cover part, two opposing side walls, and wall surfaces delimiting the receiving space. During the charging process, the socket receiving part, the cover part, and the two opposing side walls essentially close the opening in the protective cover. This means that even after the charging socket has been pivoted out, no water can enter the receiving space or the charging socket itself, since it remains in a protected space and its fastening section is therefore still inaccessible from the outside.
[0020] In an alternative embodiment, the charging socket is immovably attached to the protective cover either directly or via an intermediate element. This allows the charging socket to be attached indirectly or directly to the protective cover below the protective cover, yet still easily accessible from the outside. The charging socket is located below the surface serving as a walkway or driveway, thus preventing damage. The charging socket can be pre-assembled to the intermediate element and removed with it for inspection purposes.
[0021] The intermediate element is attached to the protective cover from the side opposite the surface serving as the walking or driving surface and, together with the charging socket, closes the opening in the protective cover. The closure, which covers the charging socket itself and the intermediate element, prevents water from entering the receiving space, or it also directs water flowing onto the intermediate element away from the charging socket. Accessible fastening below the walking surface is thus realized cost-effectively, as the cover can be designed as an essentially flat plate that does not require machining on its surface.
[0022] Preferably, the intermediate element has a flange surface through which the intermediate element is screwed to the protective cover. This creates an easily removable connection that simplifies external inspection and, thanks to the flange surface, can also be designed to be highly leak-proof.
[0023] Furthermore, it is advantageous if the receiving space is defined by a receiving container arranged within the receiving space or by wall surfaces of the base body and the protective cover. This receiving container can be made of metal, particularly steel, or a weather-resistant plastic, for example. No additional components are required, making manufacturing simple.
[0024] It is particularly preferred if the charging socket has a flange serving as a fastening section, with which the charging socket is attached to the protective cover or the intermediate element. This flange can also be easily sealed and allows both easy attachment and possible detachment of the charging socket from the intermediate element or the protective cover for inspection and maintenance purposes or for replacement.
[0025] The flange of the charging socket is advantageously attached to the intermediate element on the side opposite the protective cover, thus preventing access to the screw connections both during charging and outside of charging times without loosening the protective cover.
[0026] In order to ensure reliable sealing in the area of the charging socket and thus prevent water from penetrating from the outside into the charging socket or the receiving space, a flat seal is arranged between the intermediate element or the protective cover and the flange of the charging socket.
[0027] A corresponding seal between the intermediate element and the protective cover via a flat seal arranged there also prevents water from penetrating into the receiving space, thereby preventing damage to any electronic components present there.
[0028] This creates a curb, paving stone, or kerb charging device for charging an energy storage unit of an electrically powered vehicle. This reliably prevents water from penetrating both the mounting space of the curb, paving stone, or kerb unit and the charging socket itself. Above all, the charging socket is protected against unauthorized removal. Only authorized personnel with the tools to open the protective cover can reach the mounting section. However, once the protective cover is removed, the mounting section is easily accessible, allowing the charging socket to be easily removed or replaced for testing or maintenance purposes. It can also be removed from the curb with an electronics unit, if present, for external testing.
[0029] Two non-limiting embodiments of a curb, paving stone or kerb charging device according to the invention for charging an energy storage device of an electrically driven vehicle are described below using the example of two curb charging devices with reference to the figures.
[0030] Figure 1 shows a schematic diagram of a road with a curb loading device according to the invention in plan view. Figure 2 shows a perspective side view of a section of a curb loading device according to the invention.
[0031] Figure 3 shows the perspective side view of the section of the curb loading device according to the invention according to Figure 2 with the first protective cover part partially cut away.
[0032] Figure 4 shows a perspective side view of the intermediate element from Figure 3.
[0033] Figure 5 shows a perspective side view of a pivotable intermediate element of a curb loading device.
[0034] Figure 6 shows a section of the curb loading device according to the invention with pivotable intermediate element according to Figure 5 with the base body cut off.
[0035] Figure 1 shows a walking or driving surface 10 in the form of a sidewalk, which is bordered on one side by a house wall 12 and on the other side by a curb 14 formed by several stone elements 16 and curb charging devices 18 according to the invention, forming a boundary to the street 19. On the side of the sidewalk facing away from the curb 14, there is an energy source 20 in the form of a power connection connected to the power grid. The energy source 20 is connected to the curb or kerb charging devices 18 via underground power supply cables 22. Charging sockets 24 are arranged on the curb charging devices 18, into which a plug 26 is inserted. The plug 26 is connected via a cable 28 to an energy storage device 30, in particular a battery of an electrically powered vehicle 32, so that this energy storage device 30 can be charged via the energy source 20.The curb charging device 18 shown in Figures 2 and 3 consists of a curb unit 34, which has a base body 36, which is made, for example, of concrete or plastic and may have fiber reinforcements or armouring, and in which a receiving space 38 is formed, into which at least the power supply cable 22 protrudes, but various electronic components for charging can also be arranged. The receiving space 38 can, in particular, be essentially hollow cuboid-shaped and has one side open to the surface of the sidewalk 10, which is closed by a protective cover 40, the outward-facing surface 42 of which forms the outer part of the walking or driving surface 10.
[0036] The protective cover 40, which is made in particular of steel, is attached to the base body 36 or a receiving container 39 (not shown) arranged in the receiving space 38 and closes the upwardly facing, open side of the receiving space 38, in particular with the interposition of a seal (not shown). In addition, the protective cover 40 also rests on an upper side of the base body 36 and, viewed in the longitudinal direction, also extends over the ends of the receiving space 38.
[0037] The protective cover 40 has a rounded impact wall 44, which covers an edge between the top of the base body 36 and a side surface 46 of the base body 36 facing the street. The protective cover 40 can be attached using screws (not shown). The protective cover 40 limits the receiving space 38 upwards to the walking or driving surface 10.
[0038] The protective cover 40 has an opening 48 into which the charging socket 24 with its contacts 50 protrudes from the receiving space 38 toward the surface 42. The charging socket 24 is closed to the surface 42 by a hinged socket cover 52. This socket cover 52 is connected to the protective cover 40 via a hinge 54 and, when closing the charging socket 24 outside of the charging process, rests with its outer edge region 56 on a step 58 on the protective cover 40, which is formed on a radial boundary wall 60 of the opening 48. Accordingly, the opening 48 tapers towards the receiving space 38 due to the step 58.In this radially outer region, the protective cover 40 has the same height as the section 62 of the boundary wall 60 formed above the step 58, so that a surface 64 of the socket cover 52 essentially forms a common plane with a surface 42 of the protective cover 40 and thus forms part of the walking or driving surface 10. Except in the region of the socket cover 52 opposite the hinge 54, the section 62 of the boundary wall 60 has only a gap to the outer circumference of the socket cover 52. In the inner region facing the charging socket 24, the socket cover 52 has a projection 66 which has essentially the same radial extent as the section of the charging socket 24 projecting into the opening 48, so that this part is placed sealingly onto the charging socket 24 when the latter is closed. Of course, the height of the charging socket 24 to the socket cover 52 and the height of the step 58 must be coordinated accordingly.A seal 70 can also be provided in this area on the socket cover 52 or, as shown in Figures 2 and 3, on an outer wall 68 radially delimiting the charging socket 24 in order to prevent water from penetrating into the charging socket 24 when closed.
[0039] The socket cover 52 has its greatest width in an area 72 adjacent to the hinge 54. With this width, it extends approximately to the middle of the charging socket 24, from where it tapers with increasing distance from the hinge 54 to the end 74 remote from the hinge 54. At this remote end 74, the socket cover 52 no longer rests on the step 58, but is spaced apart from the protective cover 40 so that the socket cover 52 can be grasped from below and opened manually. For this purpose, a recess 76 is formed at this end 74 on the protective cover 40, through which a pin 78 of a locking actuator for the socket cover 52 protrudes. When closed, the locking actuator engages in a corresponding locking opening 80 on the underside of the socket cover 52, so that the latter cannot be opened without prior authentication.Once authentication is complete, the pin 78 is extended from the locking opening and the socket cover 52 can be opened by the user.
[0040] As already described above, the charging socket 24 itself is located below the surface 42 in order not to protrude above the surface 42 and to be able to arrange the socket cover 52 above the charging socket 24, so that normally there would be a risk of water ingress at least when opening the socket cover 52, which in this case is prevented by the possible drainage of water from the socket cover 52.
[0041] This water is then diverted to an intermediate element 82, which is screwed from the receiving space 38 and thus from the inside, with the interposition of a first flat seal 84, via a circumferential flange surface 86 formed on the intermediate element 82, to the protective cover 40 and is shown in Figure 4. This intermediate element 82 also serves as a support for the charging socket 24 and, with it, closes the opening 48 in the protective cover 40. For this purpose, the charging socket 24 is screwed via a fastening section 88 of the charging socket 24, which in the present embodiment is designed as a flange 90, with the interposition of a second flat seal 92, against a flange surface 94 formed on the side of the intermediate element 82 opposite the protective cover 40. The flange 90 is in particular manufactured in one piece with the radially delimiting outer wall 68 of the charging socket 24, but is located significantly axially offset from the axial end of the radially delimiting outer wall 68.Accordingly, the charging socket 24 projects through a through opening 96 which is formed in the intermediate element 82 and is arranged within the flange surfaces 86, 94.
[0042] A drainage surface 98 is formed on the intermediate element 82, which completely radially surrounds the outer wall 68 of the charging socket 24 and extends below the hinge 54 and to the step 58, as well as at the end 74 remote from the hinge 54 to the recess 76. The drainage surface 98 is bounded radially outwardly by a side wall 100, from which the first flange surface 86 extends, and radially inwardly by the outer wall 68 of the charging socket 24.
[0043] The upwardly directed drainage surface 98 of the intermediate element 82 is designed to slope downward toward a drainage opening 102 in the side wall 100. This drainage opening 102 is located at the lowest point of the drainage surface 98 and opens into a drainage channel 104, which is formed in a first section 106 on the intermediate element 82 and continues outward in a second section 108 through a groove on the base body. This second section opens outward between the base body 36 and the protective cover 40, allowing the water to flow forward toward the street 19.
[0044] The intermediate element 82 thus allows for a simple water drain and, at the same time, provides a means for pre-assembly and disassembly of the charging socket 24 for authorized personnel, since the charging socket can be easily removed and is easily accessible after opening the protective cover. This is achieved by locating the charging socket 24 in a space 110 enclosed on all sides, both during and outside of the charging process. In this case, this space is delimited by the base body 36 and / or the receiving container 39, the protective cover 40, and the intermediate element 82.
[0045] However, it is pointed out that the charging socket 24 can also be fastened directly from the inside to the protective cover 40 or the described intermediate element 82 can also be manufactured in one piece with the protective cover 40, so that the flange 90 or the fastening section 88 of the charging socket 24 is in this case screwed directly from the inside to the protective cover 40.
[0046] An alternative embodiment is shown in Figure 5. The charging socket 24 is designed to be pivotable. This means that, when not in use during the charging process, the opening 48 is closed by the intermediate element 82, which has a pivotable cover part 112 that is attached to the protective cover 40 via a pivot 114, which is designed here as a hinge. In this state, an outer region 116 of the cover part 112, with the exception of the side on which the pivot 114 is formed, rests on a corresponding circumferential shoulder that surrounds the opening 48. This cover part 112 is connected to a socket receiving part 118, which in its first section is designed as a rectangular plate 120 that has the through-opening 96 through which the charging socket 24 protrudes.This plate 120 extends perpendicular to the cover part 112 and is subsequently continued as a circular arc section 122, so that the plate 120 and the adjoining circular arc section extend over an angle of approximately 90°. The flange 90 of the charging socket 24, which serves as the fastening section 88, rests against the plate 120 of the socket receiving part 118 on the side facing the pivot joint 114 of the cover part 112 and is also screwed to the socket receiving part 118 from this side. Two struts 123 extend straight from the pivot joint 114 to the end of the socket receiving part 118, so that a quarter-circle sector is delimited by the cover part 112, the socket receiving part 118, and the struts 123.The two open sides of this defined quarter-circle sector are closed by two quarter-circle-sector-shaped side walls 124, which are screwed or glued to the struts 123, the socket receiving part 118, and the shoulder 126 formed on the lower surface of the cover part 112. The front side wall 124 is shown unassembled in Figure 5 and fully assembled in Figure 6. One of the side walls 124 can also be manufactured in one piece with the struts 123, the socket receiving part 118, and / or the cover part 112.
[0047] Thus, a space is formed on the intermediate element 82 that is only open between the two struts 123. However, this intermediate element opening 128 is also located when the charging socket 24 is extended and thus during the charging process within the receiving space 38. The opening 48 in the protective cover 40 is correspondingly closed by the intermediate element 82 or the socket receiving part 118, the cover part 112, and the two side walls 124, which accordingly slide directly past the long sides 130 of the opening 48, while the socket receiving part 118 slides along the open transverse side 132 of the opening 48. For this purpose, a brush seal (not shown) or an elastic sealing lip can be provided on the long sides 130 and the transverse side 132 to further improve the seal.In this state, the charging socket 24 is thus delimited by various wall surfaces, namely inner walls 134 of the receiving space 38 or the receiving container 39, the protective cover 40 as well as the intermediate element 82 and the side walls 124. Accordingly, although the charging socket 24 is accessible from the top for inserting a plug, it is also protected from intervention by unauthorized persons in this state because the fastening section 88 is located in a space 110 that is enclosed on all sides and is only accessible by loosening the protective cover and, if applicable, the side walls 124. The charging socket 24 additionally has a socket cover 52 that shields the contact side of the charging socket 24 and is pivoted by hand for inserting the plug.This is pivotally mounted on the side of the charging socket 24 facing away from the cover part 112 and can have a surface 138 with which the circular arc section 122 is extended beyond the charging socket 24, so that even when the charging socket 24 is extended at the beginning of the movement, no gap is created to the transverse side 132 of the opening 48.
[0048] The intermediate element 82 is connected via a push / pull rod 140 for pivoting the charging socket 24 to an actuator (not shown), which is actuated for charging upon appropriate authentication, whereupon the charging socket 24 is moved into the state shown, while outside the charging process the cover part 112 rests on the opening 48.
[0049] This creates a design that, on the one hand, protects both the charging socket itself and the interior of the curb unit from water ingress in all conditions, and, on the other hand, reliably prevents unauthorized removal of the charging socket, both in the retracted and extended positions for a pivoting charging socket and for a permanently installed charging socket. Nevertheless, the charging socket is easy to install, remove, or replace for maintenance.
[0050] It should be clear that various design modifications are possible compared to the described embodiments. For example, in addition to the pivoting charging socket, a liftable charging socket could also be used, which would then also be appropriately secured from the inside and encapsulated for all conditions. Other shapes of the intermediate elements or mounting sections are also conceivable. Above all, the charging socket can also be screwed directly to the protective cover from the inside.
