Description

The subject relates to a charging station for electric vehicles.

The construction of the charging infrastructure is of crucial importance for the nationwide establishment of electromobility. For this purpose, it is necessary to install in public as well as in part public spaces charging stations for electric vehicles to a large extent. The charging stations should fit into the streetscape and are therefore usually designed as charging stations. Charging columns are characterized by a compact design with a small footprint. The charging stations are usually stela-like and have integrated or connectable charging electronics.

As mentioned, the extensive expansion of the charging infrastructure is a key factor in the acceptance of electromobility. Therefore charging stations must be installed as widely as possible and in large numbers in a short time. This is a challenge with regard to the design, construction and actual installation on site of the charging stations, since the mass use of the charging stations they must be produced on an industrial scale and particularly easy, preferably by a single person, should be installed on site.

This is only partially the case with previous charging stations. On the one hand, the on-site assembly is complex and expensive, on the other hand, the electronics in the charging stations can not be produced inexpensively and in large quantities.

Against this background, the object was the object to provide a charging station for electric vehicles available, which is particularly inexpensive to produce in bulk. This object is achieved by a charging station according to claim 1.

It has been objectively recognized that a housing of the charging station can be mounted particularly easily on a concrete foundation if a supporting structure runs inside the housing. The stele-like shape of the charging station leads to high torques in the area of the base-side attachment of the supporting structure. The supporting structure is fastened to a ground foundation via a fastening bracket. Due to the high forces that can occur, for example, up to 1500 Nm, the mounting bracket is exposed to heavy mechanical loads. In order to accommodate these loads, it is proposed that the mounting bracket is formed of a metal casting. The running within the charging station or the charging column housing support structure is attached in the region of its bottom via a mounting bracket with the ground foundation.

In order to avoid predetermined breaking points, it is proposed that the mounting bracket is firmly bonded to the supporting structure. It is preferred if the mounting bracket circumferentially cohesively connected to the support structure, in particular welded.

According to one embodiment, it is proposed that the support structure is a metal profile which extends from the attachment bracket into a head region of the charging column housing. The mounting bracket forms the only mechanical connection between the charging column housing and the ground foundation Here, in particular, a charging column head is connected to the supporting structure and a charging base is connected indirectly via the charging column head with the supporting structure.

According to one embodiment, it is proposed that the charging column housing is formed from a charging base foot and a charging column head. The charging column head preferably has in its interior a stop for the supporting structure. If the charging column head is placed on the supporting structure, the stop defines a maximum insertion depth of the supporting structure into the interior of the charging column head. Preferably, the stop is such that in this case an alignment between the charging column head and the support structure is such that the charging column head can be connected directly to the support structure. In this case, it is possible, for example, for the load-bearing head to be mounted on the support structure as far as possible by mounting it on the supporting structure. At this moment, a passage opening in a wall of the charging column head is aligned with a passage opening in the supporting structure, so that the charging column head can be fastened to the supporting structure, in particular screwed.

The attachment between the charging column head and the supporting structure is preferably in the region of a receptacle (a recess) in a front surface of the charging column head. In this return the charging electronics can be used. The result is that the charging station in the mounted state has an outer, non-perforated lateral surface. Only a circumferential gap between the Ladesäulenfuß and the charging column head, as well as a gap between the receptacle for the charging electronics and the charging electronics is given. Otherwise, the housing is free from any mechanical damage. From the outside in the assembled state can not be seen how the housing is arranged on the ground foundation. The only fixation of the charging column head takes place at the Support structure, preferably in the area in which subsequently the charging electronics is inserted into the charging column head. This has many advantages, including a so that an integrated anti-theft device is guaranteed.

According to one exemplary embodiment, it is proposed that the fastening bracket has radially outwardly directed spring elements on at least one side wall, preferably two mutually opposite side walls, the spring elements exerting a spring force on an inner wall of the charging column housing in the assembled state of the charging column. The mounting bracket is located in the area of the ground foundation. The mounting bracket has a larger footprint than the support structure. In particular, the mounting bracket has a base area which corresponds approximately to the cross section of the interior of the Ladesäulenfußes. The mounting bracket is preferably smaller in their edge dimensions, as the edge dimensions of the inner opening of the Ladesäulenfußes.

In the forming annular space between the mounting bracket and the inner wall of the Ladesäulenfußes engage the spring elements. For assembly, the mounting bracket is first aligned with the ground foundation. Then the charging column foot is slipped over the supporting structure and the mounting bracket. In this case, the bottom-side opening of the Ladesäulenfußes is slipped over the mounting bracket together with spring elements. The spring elements are thereby tensioned, so that they exert a radially outwardly acting spring force on the Ladesäulenfuß in the region of the bottom. As a result, the Ladesäulenfuß is mounted radially on the mounting bracket A storage axially in the longitudinal direction of the support structure can then be done exclusively indirectly via the charging column head. Without the charging column head, the charging column foot is movable axially along the support structure and mounted radially to the support structure by the spring elements. After the charging column head has been fastened to the supporting structure, the charging column foot is fastened to the charging column head and is thus also mounted axially relative to the supporting structure.

According to one embodiment, it is proposed that the spring elements are U-shaped and point with their opening in the direction of a base foundation. This ensures that when slipping the Ladesäulenfußes on the mounting bracket, the spring elements are aligned with the inner surface of the bottom opening of the Ladesäulenfußes and the Ladesäulenfuß is slipped over the spring elements without the bottom edge of the Ladesäulenfußes hooked in a spring element.

According to one embodiment, it is proposed that the mounting bracket has three receptacles for adjusting elements of a base foundation. In this way, the mounting bracket can be fixed to the ground foundation and arranged on the mounting bracket support structure are placed vertically. The three control elements allow the mounting plane of the mounting bracket to be defined. If this horizontal and the support structure mounted vertically on the mounting bracket, resulting from the orientation of the mounting bracket on the control elements in a horizontal vertical alignment of the support structure. Also this assembly can be done by a single person. The supporting structure is considerably lighter than the entire housing of the charging station. The installer only has to place the mounting bracket together with the supporting structure on the adjusting elements, align the mounting bracket using the adjusting elements and fix it to the adjusting elements. Subsequently, a vertical mounting of the Ladesäulenfußes and the charging column head can be done easily. In particular, the actuating elements are threaded rods. Also, the mounting bracket can be aligned with the adjusting elements relative to a ground foundation.

When using threaded rods, it is possible, for example, first to arrange nuts between the mounting bracket and the ground foundation, which are adjustable relative to the ground foundation along the threaded rod. This makes it possible to determine the mounting plane of the mounting bracket and in particular by adjusting the position of the nuts relative to the ground foundation to align the mounting bracket in a horizontal. Subsequently, the mounting bracket between the first nuts and then screwed onto the threaded rods second nuts are fixed in place. If the support structure is perpendicular to the mounting plane of the mounting bracket, this is therefore perpendicular and the installation of the charging station is subsequently particularly simple.

In order to ensure increased rigidity of the charging station, it is proposed that the supporting structure is at least partially formed as a U-profile. This results in a high moment of area of inertia of the supporting structure with little use of material.

The attachment bracket preferably has a passage for at least one power cable in a central region. This allows power cables to pass through the center area of the mounting bracket from the ground foundation only to supporting structures. Since the mechanical load is the lowest in the center region of the mounting bracket, the passage is preferably arranged there. Of the Passage is preferably circumferentially encompassed by the mounting bracket. On the mounting bracket, the support structure is arranged. The support structure preferably surrounds the passage with at least three walls. The power cable routed through the passage is then routed between three walls of the support structure to the charging column head. The fact that the passage is in the center region, the mounting bracket can be adapted over a large area on the inner cross section of the charging column foot.

If two separate charging electronics are arranged in the charging column head, they can be supplied via a respective separate power cable. These two power cables can be routed through the base foundation and the passage to the inside of the charging column foot. Preferably, the two charging electronics are arranged on opposite front surfaces of the charging column head.

In order to enable a particularly simple connection of the power cables to the charging column electronics, it is proposed that the supporting structure has an opening in a side wall and that in an assembled state, at least one power cable is guided through the opening. The power cables are led through the passage and are enclosed on three sides by the supporting structure. The power cables are then routed up the support structure with a power cable passing through the opening in the side wall. The power cables are then on two opposite sides of the support structure and can be guided from there to two opposing front surfaces or openings within the front surfaces and connected there with charging electronics.

According to one embodiment, it is proposed that the fastening bracket is arranged in a mounted on the actuating element state at a distance from a base foundation. This makes it possible to align the mounting bracket in a horizontal, even if the ground foundation is not completely aligned horizontally.

It has also been recognized that the housing of the charging station in a particularly simple and inexpensive industrial manufacturing process must be produced. On the other hand, however, all the requirements with regard to electrical safety as well as the insertion is to meet the streetscape. The housing must completely enclose the electrical components, which requires a housing cover. On the other hand, the charging station must be formed stolen, in order to keep the area consumption low. For this reason, it is proposed that the charging column foot is extruded, in particular continuously cast or extruded, and that the charging column head is die-cast. In the continuous casting process for the charging column foot, it is possible to produce a tubular profile in a continuous process. After the profile has been cut to length, the charging column foot is mechanically almost finished and can subsequently be supplied, for example, merely to a powder coating, a coating or another coating.

The lid of the housing is formed by the charging column head, which is die-cast. Through the die-casting process, any shape of the lid can be made. By separating the manufacturing process of Ladesäulenfuß and Ladesäulenkopf results on the one hand, a cost-effective variant for the production of Ladesäulenfußes and on the other hand, a high degree of design freedom in terms of the design of the charging column head.

Preferably Ladesäulenfuß and Ladesäulenkopf are made of an aluminum material. Also, the use of a steel material is possible. Preferably Ladesäulenfuß and Ladesäulenkopf are made of the same metallic material.

As already mentioned, the charging column head is formed as a lid. It is proposed that the charging head be lid-shaped with side walls (side surfaces and front surfaces) and an open bottom. In the charging column head, a recess may be provided in at least one side wall, which is formed for receiving a charging electronics The receptacle may be arranged trough-shaped in a side wall of the charging column head and housed the charging electronics in a housing suitable for this purpose, trough-shaped record.

The closed side walls lead to a circumferentially closed lid. Only the bottom-side opening corresponds in the mounted state with the interior of the charging column foot, so that a virtually free passage between the interior of the charging column foot and the interior of the charging column head is ensured. Through this passage, an electrical connection to be connected charging electronics can be ensured with a power supply network.

Preferably, the charging base is placed on a foundation. In this case, a connection cable with a power supply network through the inside of the charging column foot is guided from the foundation floor to the charging column head. In the charging column head, the charging electronics can be arranged in a recess, which then for connecting the Connecting cable is used with the power grid. Therefore Ladesäulenfuß and Ladesäulenkopf are initially free of electronic and electrical components in the assembled state and only lead the connection cable to a power grid.

According to one embodiment, it is proposed that an upper opening of the charging column foot in the mounted state of the charging station is aligned with an open bottom of the charging column head. The passage between the charging column head and the charging base foot thus formed allows the connecting cable to be guided as well as a supporting structure, which will be described below. The housing formed by the Ladesäulenfuß and the Ladesäulenkopf is preferably hollow and includes only the support structure and the connecting cable to a power grid. Other components that do not serve to connect Ladesäulenfuß with Ladesäulenkopf one hand and Ladesäulenkopf with support structure on the other hand, are not found inside the housing formed from Ladesäulenfuß and Ladesäulenkopf.

For mounting the housing, it is proposed that a support structure is arranged in the charging column foot, which extends from the lower end of the charging column foot to beyond the upper end of the charging column foot. This support structure is used for mechanical attachment of both the charging column foot and the charging column head to the ground foundation.

It is proposed that the charging column foot is fastened to the support structure only via the charging column head. The mechanical stability of the charging column foot is thus ensured exclusively via the charging column head. During assembly, the charging column foot is first slipped over the supporting structure. Subsequently, the charging column head is fastened to the supporting structure and finally the charging column foot is connected to the charging column head, in particular screwed to the charging column head. This assembly is possible by a single person. Ladesäulenkopf and Ladesäulenfuß are very light Since they are initially free of charging electronics, the weight can be kept so low that a person can set up the charging station.

According to one exemplary embodiment, it is proposed that a circumferential annular space extend over the entire height of the charging column foot in the charging column foot. The annulus is formed between the support structure and the inner wall of the charging column foot. Other mechanical components are not present in the charging column foot. Only at the bottom of the support structure, a mounting bracket may be provided which corresponds to a bottom opening of the Ladesäulenfußes.

As already explained, the charging column head is connected to the supporting structure. In this case, in particular a screw is conceivable. The charging column head is first connected to the supporting structure. Then the charging column foot is connected to the supporting structure via the charging column head. This structure makes it possible to set up the housing by only one person. First, the supporting structure is aligned on the ground foundation. Subsequently, only the loading column foot has to be slipped over the supporting structure and the head fastened to the supporting structure. Finally, the Ladesäulenfuß is attached to the charging column head and is thus indirectly attached to the support structure. A separate alignment of the charging column foot is not necessary.

As already explained, an aluminum material can be used for the housing. It is proposed that the charging column foot is formed of extruded aluminum and / or that the charging column head is formed on die-cast aluminum. Continuous casting is suitable for simple, hollow profiles, as represented by the charging base. The die-cast head is die-cast to give it the freedom of design that is needed, for example, to ensure the mounting of charging electronics.

The charging base has a tubular, octagonal cross-sectional profile. The long edges of the profile are provided with a chamfer, so that sharp edges are avoided.

On the bottom side, the charging column head also has a tubular cross-sectional profile adapted to the charging column foot. The cross-sectional profile of the charging column head is on the bottom side congruent to the cross-sectional profile of the Ladesäulenfußes.

To close the charging head, it is proposed that the side surfaces of the side walls of the charging column head extend semicircular or elliptical from the open bottom to an upper apex. Front surfaces are provided between the side surfaces, wherein at least one front surface of the charging column head has an opening for receiving charging technology. In the front surface, which has the opening or intake of charging technology is also closed.
Through the use of die casting, it is possible to produce various forms of Ladesäulenkopfes, each corresponding to the same Ladesäulenfuß. Thus, it is for example possible to widen the side surfaces, so that both in the first and in the second front surface of a Opening for receiving charging technology can be provided. Such a charging column head can also be plugged onto a physical Ladesäulenfuß.

The opening in the front surfaces is preferably trough-shaped and has a bottom or circumferential side walls which extend from the bottom to the front surface. The bottom separates the receptacle from the inside of the charging column head. Only for the mechanical fixation of the charging column foot on the charging column head, passage openings (for example bores) can be provided. In addition, passageways may be provided in the sidewalls or the floor to lead a connection cable to a power supply network from the interior of the housing to the outside. In the opening then a charging electronics can be used, which is received by the opening.

In order to prevent disturbing projections or edges from occurring on the outer lateral surface of the housing, it is proposed that a web is arranged on an end edge of the charging column foot. This web preferably jumps back from the outer lateral surface of the charging column foot. At a bottom edge of the charging column head, a circumferential receptacle for the web can be arranged. This receptacle can spring back from the inner lateral surface of the charging column foot. The outer surface of the stela remains flat. In the assembled state of the charging column head and charging column foot, the receptacle receives the web in such a way that it surrounds it circumferentially. Thus, only a circumferential seam between the charging column foot and the charging column head forms. The fact that the receptacle embraces the web, rainwater can not easily penetrate into the interior of the housing.

As already mentioned, the web can spring back radially inwards from the inner lateral surface of the charging column foot. It is also possible that the receptacle is aligned circumferentially with the outer surface of the Ladesäulenfußes. The receptacle may be a return on the inner circumferential surface of the charging column head.

For fastening the charging column foot to the charging column head, it is proposed that in the region of the web radially inwardly directed fastening bodies are arranged and that in the region of the receiving means radially inwardly facing fastening bodies are arranged. The attachment body may be, for example, flanges through which through-holes for receiving screws are arranged. The mounting body engage in the assembled state in such a way that the Ladesäulenfuß is positively connected to the charging column head. It can be pulled by connecting the Ladesäulenfuß axially in the direction of the charging column head and thereby move relative to the support structure.

By this axial movement relative to the support structure, whose position is fixed to the ground foundation, results in the assembled state that the Ladesäulenfuß by attachment to the Ladesäulenkopf spaced from the ground foundation is by this spacing ensures that even with unevenness in Bodenfundament the Ladesäulenfuß accordingly the preferred vertical orientation of the support structure is also aligned with the foundation.

The charging station includes a charging base and a charging station head. In the Ladesäulenfuß runs a support structure. The supporting structure is to be fastened in the area of the base of the loading column foot by means of a fastening bracket with a base foundation.

For a particularly simple installation, even by a single fitter, it is proposed that the charging column head is directly connected to the supporting structure and that the charging base is connected to the supporting structure via the charging column head. This means that an axial bearing of the charging column foot takes place in a longitudinal axis of the supporting structure exclusively via the charging column head. Although it is possible that the Ladesäulenfuß is mounted on the bottom side radially on the mounting bracket, the axial storage without degree of freedom, however, takes place exclusively on the charging column head. Movement of the charging column foot relative to the supporting structure in a direction along the longitudinal axis of the supporting structure is prevented when the charging column foot is mounted on the charging column head. The charging column head is connected to the supporting structure. The charging column foot is thus connected to the supporting structure via the charging column head. Ladesäulenkopf and Ladesäulenfuß are preferably in two parts.

For attachment of the charging column foot to the charging column head fastening means are provided. The fastening means are preferably arranged exclusively in the interior, that is to say on the inner peripheral surface of the charging column foot and the charging column head. In particular in the charging column head, the fastening means are provided in an opening of a front surface which is provided for receiving a charging electronics. Once the charging head has been connected to the charging base and the charging electronics have been inserted into the opening, the charging column head can only be removed from the charging base when the charging electronics have been removed.

The fastening means are preferably such that the charging column foot is pulled axially through the fastening means in the longitudinal direction towards the charging column head and is movable relative to the supporting structure. After the supporting structure has been mounted on the ground foundation, the charging column foot is slipped over the supporting structure and then the charging column head is mechanically fixed to the supporting structure. The charging column head is then mounted on the supporting structure without any degree of freedom. If the charging column foot is fastened to the charging column head via the fastening means, then the charging column foot is moved axially in the longitudinal direction of the supporting structure relative to the supporting structure towards the charging column head. This results in a gripping around a bottom opening of the charging column head to a head-side, circumferential ridge of Ladesäulenfußes. The charging column head surrounds in the assembled state circumferentially the charging base, so that only a circumferential gap between Ladesäulenkopf and Ladesäulenfuß is present The fastening means are preferably arranged in the opening for receiving charging electronics, so that in the mounted state, no fasteners are visible from the outside.

In the charging column head, the fastening means may for example be mounted on a flange such that they are axially fixed. That is, when the charging head is connected to the supporting structure, the fastening means undergo a stop in one direction towards the ground foundation and are thus axially fixed. About this stop, the tightening force with which the charging base is tightened to the charging column head, introduced into the charging column head.

By attaching the charging column foot to the charging column head, the charging column foot is raised relative to the attachment bracket and / or a ground foundation. Here, the Ladesäulenfuß is moved in a direction parallel to the longitudinal axis of the support structure in the direction of the charging column head.

When mounted, the charging base is connected to the supporting structure via the charging column head. Bodenseitig the Ladesäulenfußes storage of Ladesäulenfußes takes place on the mounting bracket of the support structure by outwardly directed spring elements. This results in a radially outwardly directed, resilient mounting of the charging column foot on the mounting bracket.

The support structure protrudes from the mounting bracket through the charging column foot into the charging column head. In the area of the charging column head, the supporting structure is connected to the charging column head. For this purpose, fastening means are provided for connecting the charging column head to the supporting structure. These fastening means are provided in particular in the region of an opening in a front side of the charging column head. In particular, the fastening means for screwing the charging column head are provided on the support structure. The opening in a front side of the charging column head is preferably suitable for receiving charging electronics. In particular, the opening is trough-shaped with a bottom, which springs back from the outer lateral surface of the front side and substantially circumferential side walls connecting the bottom with the outer lateral surface of the front side formed. The opening is preferably congruent with an outer peripheral surface of the charging electronics, which is inserted into the opening.

Between an upper end of the support structure and the mounting bracket, the support structure is formed as a U-profile. As a result, a particularly high flexural rigidity of the support structure is achieved.

Ladesäulenkopf and Ladesäulenfuß are joined together in the assembled state. Here, the charging base foot engages in a bottom opening of the charging column head. There forms a contact surface between Ladesäulenfuß and Ladesäulenkopf.

The contact surface is formed, in particular, by a web of the charging column foot which is located in the mounted state, wherein the web rests on an inner wall of the charging column head in the region of the bottom-side opening. This positive locking ensures at least a radial bearing of the charging column foot on the charging column head. An axial bearing takes place by the fastening means, in particular a screwing of the charging column foot on the charging column head.

The charging column head is connected to the supporting structure. This connection is in particular such that the charging column head is connected to the supporting structure without any degree of freedom.

The compound is preferably clamping, as it is particularly fault tolerant. By screwing a clamping element, so that it fixes the charging column head clamped to the support structure, the storage of Ladesäulenkopfes can be realized on the support structure.

In order to keep the outer surface of the charging column housing free of fasteners, it is proposed that the attachment of the charging column head is provided on the support structure in the region of an opening for receiving a charging electronics. If the charging electronics are inserted into the receptacle, the fastening means can no longer be achieved without having to remove the charging electronics. For this purpose it is proposed that in the opening for receiving the charging electronics in the charging column head inner intermediate wall is provided. This partition may be, for example, the bottom of the opening or a side wall of the opening. The side wall is in the assembled state between the support structure and an opening in the lateral surface of the charging column head. This opening is preferably in a front side of the charging column head and congruent with an outer peripheral surface of a charging electrical system.

At the intermediate wall, a receptacle for a clamping element may be formed and the clamping element is clamped in the receptacle via fastening means engaging in the supporting structure. Thus, it is for example possible that the clamping element is screwed relative to the support structure and is thereby pressed with a clamping force against the intermediate wall, so that the intermediate wall between the clamping element and the supporting structure is clamped.

The Ladesäulenfuß is mounted radially fixed to the charging column head and mounted by fastening means with a degree of freedom in the axial direction of the charging column head. By embracing the Ladesäulenfußes by Ladesäulenkopf the Ladesäulenfuß is radially mounted on the charging column head without degrees of freedom. Are the fasteners tightened, the Ladesäulenfuß is stored without degree of freedom at the charging column head. The supporting structure is completely enclosed by the charging column head and the loading column foot. In this case, a receptacle for a charging electronics can be provided in the region of the charging column head.

This receptacle can be trough-like with a bottom and side walls. The receptacle is preferably provided in at least one front side, in particular a flat surfaces of the charging column head. It is possible that two or more receptacles are provided in flat side walls or front surfaces of the charging column head.

1a shows a ground foundation 2 , In the ground foundation 2 are threaded rods 4 admitted. On the threaded rods 4 is a mounting bracket 6 attached. At the mounting bracket 6 is a supporting structure 8th connected. The supporting structure 8th is in its longitudinal axis 8a perpendicular to a surface plane 6a the mounting bracket 6 , Like in the 1 can be seen, the support structure has 8th on a back wall an opening 10 on. In an upper area of the supporting structure 8th is a crossbar 12 with a hole 14 intended.

The mounting bracket 6 is a metal casting, which has a particularly high strength, so that the mounting bracket 6 by lateral forces 16 introduced torques can absorb particularly well.

At the mounting bracket are, as in the 1b can be seen, spring elements 18 arranged. The spring elements 18 are on a side surface 6b the mounting bracket 6 arranged. In the mounting bracket 6 are three shots 20 for the threaded rods 4 intended.

Further, a middle portion of the mounting bracket 6 a passage 22 through which at least one power cable can be routed. In the 1b It can also be seen that the supporting structure 8th has a U-shaped profile and with three side walls the passage 22 embraces.

To install the charging station, the ground foundation will be installed first 2 with the threaded rods 4 poured and a power cable is from the ground foundation 2 in through the threaded rods 4 clamped surface led to the outside.

Subsequently, the supporting structure 8th including mounting bracket 6 with the recordings 20 on the threaded rods 4 placed. About the threaded rods 4 lets loose the mounting bracket 6 with its surface plane 6a align horizontally. This will be the longitudinal axis 8a vertically aligned when perpendicular to the surface plane 6a stands. The mounting bracket 6 is about the threaded rods 4 at the ground foundation 2 Then fix the power cable along the profile of the supporting structure 8th to the crossbar 12 guided. An optional second power cable will pass through the opening 10 guided.

The supporting structure 8th is in the 1c shown again in a view. It can be seen that the support structure as a U-profile of the mounting bracket 6 up to the crossbar 12 extends. In the crossbar 12 is the hole 14 , The pictures 20 are at the mounting bracket 20 arranged.

After the supporting structure 8th at the ground foundation 2 is fixed, is about the supporting structure 8th , like in the 2 shown is a charging base 24 inverted The loading column foot 24 is tubular from a continuously cast or extruded aluminum material. The charging station foot 24 is first on the ground foundation 22 discontinued.

Subsequently, the charging column head 26 on the supporting structure 8th It can be seen that the supporting structure 8th in a direction along the longitudinal axis 8a over the shop floor foot 24 protrudes out and into the charging column head 26 protrudes into it.

In the charging station head 26 can be provided stops, so that the charging column head 26 on the supporting structure 8th is struck.

The charging station head 26 forms a cover of the charging column head 26 and charging base 24 formed housing of the charging station. It can be seen that within this housing, only the support structure 8th including mounting bracket 6 is arranged. In addition, one or more power cables from the ground foundation 2 into the charging column head 26 be guided. Other electrical devices are not provided in the housing. This makes the assembly particularly simple, since only a mechanical assembly is necessary, which can be performed by a technician not electrically formed.

The 3a and b show the possibilities of a cohesive connection between the mounting bracket 6 , which is formed from a metal casting and the profile of the supporting structure 8th , On the one hand, it is possible via mounting bracket 28 , which both with the mounting bracket 6 as well as the supporting structure 8th connected by welds, the supporting structure 8th with the mounting bracket 6 connect to. It is also possible the supporting structure 8th directly on the mounting bracket 6 to sit up like in the 3b is shown and provide a circumferential weld.

In the assembled state is the charging column foot 24 over the mounting bracket 6 slipped. 4 shows an embodiment in which the mounting bracket 6 on the threaded rods 4 via appropriate nuts 4a is aligned.

First, the lower nuts 4a on the threaded rods 4 screwed. Subsequently, the mounting bracket 6 on the threaded rod 4 attached The mounting bracket 6 can be over the bottom nuts 4a align so that their surface plane 6a is in the horizontal. Subsequently, the mounting bracket 6 over the upper nuts 4a on the threaded rods 4 fixed.

After the charging station foot 24 over the supporting structure 8th is the Ladesäulenfuß 24 bottom side by the spring elements 18 radially mounted. The spring elements 18 exercise radially outward acting spring forces 18a on the charging base 24 off, leaving the charging base foot 24 opposite the mounting bracket 6 is resiliently mounted in a floor area.

For fastening the charging column head 26 on the supporting structure 8th has the supporting structure 8th in the area of the transverse spar 12 a hole 14 , In this hole 14 like in the 5a shown is a screw 28 be screwed. The screw 28 leads a clamping element 30 which by the screw 28 relative to the crossbar 12 can be moved.

In the 5b it can be seen that the cross member 12 the U-shaped profile of the supporting structure 8th all around closes. The screw 28 can completely through the entire depth of the supporting structure 8th be guided. With the help of the clamping element 30 can the charging station head 26 on the supporting structure 8th mount like this in the 6a-c is shown.

6a shows a charging station head 26 in a side sectional view of the charging column head 26 has front surfaces 26a and, like in the 6b shown is side surfaces 26b ,

The side surfaces 26b extend from a bottom opening 32 of the charging column head 26 up and run in a radius towards each other and close the charging column head 26 up.

In the area of the bottom opening 32 is a rotating recording 32a provided, which for receiving a head-side web of the Ladesäulenfußes 24 is set up.

In the 6a it can be seen that on at least one front page 26 an opening 34 is provided. The opening 34 is trough-shaped with a bottom 34a and sidewalls 34b , The side walls 34b are preferably fixed, preferably in one piece with the side walls 26b and the front surface 26a educated. This can be done in particular by die-casting the charging column head 26 be achieved. By an appropriate die casting mold can be the charging station head 26 with the trough-shaped opening 34 form. The trough-shaped opening 34 serves to accommodate a charging electronics.

Like in the 6b It can be seen, the scope of the opening 34 assume a partially elliptical shape. Any peripheral shapes are possible, so that the opening 34 to the contour of one in the opening 34 can be adapted to be used charging electronics.

In the area of one of the walls of the opening 34 here as in the 6a it can be seen in the area of the ground 34a , can be a passage 34c be provided by the screw 28 can be performed. Like in the 6b it can be seen is on the ground 34a a return 36 provided, which is congruent to the clamping element 30 is.

For fixing the charging column head 26 on the supporting structure 8th will the screw 28 including clamping element 30 in the opening 34 plugged and the clamping element 30 against the return 36 pressed. By further screwing the soil 34a between the clamping element 30 and the crossbar 12 the supporting structure 8th jammed. Thus, the charging column head 26 firmly attached to the supporting structure 8th assembled.

In the 6c it can be seen that the charging column head 26 may also have different shapes, in particular with two openings 34 ' . 34 " lying on opposite front surfaces 26a are arranged. This makes it possible in a charging station head 26 to arrange two independently operable charging electronics. The fixation of the charging column head 26 on the supporting structure 8th But in the same way as described above, in particular only from one side.

For mounting, the mounting bracket is first 6 at the ground foundation 2 aligned. Then the charging station foot becomes 24 over the supporting structure 8th slipped. Then the charging station head 26 on the supporting structure 8th attached and hereby screwed as described above. The charging station head 26 is now relative to the supporting structure 8th fixed.

Subsequently, the charging column foot 24 , like in the 7 is shown by parallel to the longitudinal axis 8a running screws 38 at the charging station head 26 be fixed. These are in the opening 34 two connecting flanges 38 ' provided by the screws 38 be guided. In the area of the charging station head 26 facing opening of the Ladesäulenfußes 24 can use connection flanges 42 in the charging station foot 24 be provided for receiving the screws 38 are suitable.

With the help of screws 38 , which through the connection flange 38 ' are stored, the charging base can be 24 parallel to the longitudinal axis 8a in the direction of the charging column head 26 move and fix. This slides a frontal circumferential web 40 the charging column foot 24 , as in 7 is shown in a recording 20 of the charging column head 26 , Because the charging station head 26 relative to the supporting structure 8th through the clamping element 30 is fixed by the screws 38 an indirect fixation of the charging column foot 24 relative to the supporting structure 8th allows.

Because of the bridge 40 in the recording 20 slides, is the housing, which by Ladesäulenkopf 26 and charging base 24 is formed, protected against entering rainwater. The charging station foot 24 is in its upper region axially as well as radially through the charging column head 26 , therefore by the screws 38 as well as the recording 20 fixed. Bottom side is the charging base 24 through the spring elements 18 radially mounted.

The housing thus formed can now be equipped with a charging electronics. However, the assembly of the housing can be carried out by a single person. This enormously facilitates the mass construction of charging infrastructure.
