Definitions
- the present invention relates to a wall charging station for charging electric and hybrid vehicles, comprising a cover with a light-conducting element, which comprises a light coupling point and a light-emitting cover section with a front and a back.
- Wall charging stations have to fulfill several functions. On the one hand, wall charging stations must offer a high degree of security against destruction by external forces. Users of the wall charger must be protected from life-threatening electrical shock even if it has been subjected to shock, impact or collision with a vehicle. Nevertheless, the internal components of the wall charging station must be covered to protect them from dirt, moisture or other substances that could potentially damage the electrical components. In addition, it may be necessary to integrate additional functionalities into the wall charging station, such as user authorization, which is available in most Cases on the cover include a visual display of information to the user. It is crucial to be able to provide such information independently of the weather, time of day and/or external light sources on the cover.
- Wall charging stations made of injection-moulded plastic parts are known from the prior art, according to which a cover part has one or more viewing windows with aligned lamps behind them.
- this approach has the disadvantage that the geometry of the cover has to be changed due to the viewing window with illuminants.
- the cover needs to be more expansive to accommodate the additional components.
- the increased structure also increases the risk of an operator, vehicle or other object colliding with the cover of the charging station.
- the stability of the wall charging station can be impaired by the provision of the viewing window with light sources.
- Another approach known from the prior art proposes coupling light from a light source laterally into a viewing window and thereby creating an illuminated section in the cover of the wall charging station.
- this approach has the disadvantage that only small portions of the coupled-in light are actually emitted as light that is visible from the outside. Therefore, such viewing windows often have only a very weak light output. Such viewing window lights are therefore only suitable as background lighting in the dark. However, such viewing window lights are not suitable for emitting light signals in daylight.
- an object of the present disclosure to provide an improved wall charging station for charging electric and hybrid vehicles. It is in particular an object of the present invention to provide, in a simple, reliable and cost-effective manner, a lighting area in the cover of a wall charging station which enables light emission to be as efficient as possible.
- the task is solved by a wall charging station with the features of claim 1.
- Advantageous developments result from the dependent claims, the description and the figures.
- the present invention is based on the idea of providing a wall charging station for charging electric and hybrid vehicles, the wall charging station including a cover with a light-conducting element that includes a light coupling point and a light-emitting cover section with a front and a back.
- the rear side of the cover section has a light-reflecting element which is designed and set up to emit light incident from the light coupling point to the environment via the front side of the light-emitting cover section.
- the inventive idea is based on the approach of coupling light from a light source arranged inside the wall charging station into a light-guiding element and emitting the coupled light to the environment in a targeted manner via a specially provided light-reflecting element.
- the light coupling point can be arranged outside and behind the back of the light-emitting cover section.
- the term “light-guiding element” means a transparent or translucent body in which light can be guided at least in sections using total reflection, as occurs in light guides true to the physical laws of refraction.
- the term “light-guiding element” also means a body that is suitable for deflecting light that is coupled into the environment at a specially provided section.
- the term “coupled-in light” means the conduction of light in such a light guide. Accordingly, within the meaning of the present disclosure, the term “coupling” refers to the introduction of light into an optical fiber and the term “decoupling” refers to the guiding out of light from an optical fiber.
- a light coupling point can mean a part of a light guide with a surface via which light can be coupled into the light guide or into the light-guiding element.
- emission of light in the context of the present disclosure means the literal, diffuse or directed emission of light, for example across the material boundary of a light guide.
- Relative positional information such as front or front, in front of or behind, back, behind, behind, and orientation information such as top view, vertical, horizontal, and the like generally refer to a perspective that corresponds to the perspective of a user of a wall charging station installed on a wall.
- the information mentioned only serves to clarify the present teaching on the basis of the exemplary embodiments described here by way of example and is not restrictive.
- the light-emitting cover section is designed and set up within the meaning of the present disclosure to emit light to the environment via its front side.
- the light-emitting cover portion may be formed as a flat or curved surface.
- the light-emitting cover section can have a rectangular outer contour, for example.
- the light-emitting cover section can also have a circular outer contour or another outer contour that corresponds approximately to a logo or a symbol to be imaged.
- the light-emitting cover section can be specifically designed and manufactured for imaging a previously defined graphic.
- the definition “emit to the environment” can mean that light is emitted to the environment via a front side of the light-emitting cover section.
- it can be understood as a light emission that is suitable to be incident as light in an eye of a user of the wall charging station of the present disclosure under normal handling of the wall charging station.
- the term “light-emitting cover section” means a “luminous area” that is perceived as such by a user of the wall charging station.
- a cover within the meaning of the present disclosure can be understood to mean a sealing internal front part of the housing, also called a “front cover”. Nevertheless, within the meaning of the present disclosure, a light-emitting cover section can also mean an overlying visible housing part, which defines the shape of the housing towards the user and through which the light can be at least partially guided. Such light-emitting cover sections are sometimes called "design covers”.
- the original light source can be arranged inside the wall charging station at a distance from the actual place where the light is emitted to the environment.
- the functions “light coupling into the light coupling point” and “light emission to the environment” can be spatially separated from one another. Therefore it is not required that the light coupling point and the light-emitting cover portion are aligned.
- the light-emitting cover section can be formed in particular in areas that are used for communication, such as displaying RFID information or an operating state of the wall charging station.
- This can be advantageous, for example, if means for authorizing the energy supply are provided in the cover according to the present disclosure, for example via a coded RFID transponder or via a key switch, or other technical means that are suitable for identifying or identifying a user. to collect information for billing purposes and, if necessary, to exchange this data with central facilities via data-technical network connections.
- the light-emitting cover section can therefore be designed purely taking into account those aspects that are essential for the display or light emission per se.
- the display or light emission in the light-emitting cover section can fulfill various purposes.
- the light-emitting cover portion can simply serve as a light source.
- the light-emitting cover section can fulfill aesthetic, informative or technical functions or purposes.
- the cover according to the present disclosure aims to emit as large a proportion of the input light as possible, particularly preferably the entire input light, via the front side of the light-emitting cover section to the environment.
- the disadvantage of the low light output known from the prior art, which results from light coupled in outside and behind the light-emitting cover section, is overcome in that the rear side of the light-emitting cover section has a light-reflecting element that is designed and set up to impinge from the light coupling point Emit light to the environment via the front of the light-emitting cover portion.
- the rear side of the light-emitting cover section is fundamentally suitable for deflecting previously coupled, ie totally reflected, light on the rear side and emitting it to the surroundings via the front side.
- the back is designed to provide a surface on which coupled-in light occurs at an angle that is greater than the associated critical angle of total reflection, so that previously coupled-in light is not deflected in a totally reflecting manner on the back.
- the presence of the light-reflecting element prevents light redirected at the rear from exiting the light-emitting cover section via the rear towards the “inside of the wall charging station”. If there were no light-reflecting element, the deflection of the light that takes place on the rear side, which is not total reflection at this point, would at least partially scatter light over the rear side of the light-emitting cover section. However, the light components scattered over the back of the light-emitting cover section would be mostly light losses, since a user of the wall charging station only perceives light that is emitted over the front of the light-emitting cover section to the environment.
- the presence of the light-reflecting element at the rear of the light-emitting cover portion therefore has the advantage of maximizing the amount of light emitted to the surroundings via the front. This allows the light output to be maximized and the power required from the light source to be minimized. In this way, it can be ensured that even with a moderate output power, a clearly perceptible luminous flux can be achieved over the front side of the light-emitting cover section, even in daylight.
- the presence of the light-reflecting element on the back of the light-emitting cover section has the further advantage of minimizing heating of the wall charging station due to light absorption. This further improves the safety of the wall charging station during operation.
- the light-reflecting element can provide a reflective surface, for example, which is arranged in full-surface contact with the rear side. Consequently, according to this configuration, light is literally reflected by means of the light-reflecting element arranged on the rear side of the light-emitting cover section, ie deflected in accordance with the angle of incidence.
- the reflective element can be white and/or colored.
- the reflective element is white
- light coming from the light coupling point can be scattered on the rear side of the light-emitting cover section in all directions on this side of the light-emitting cover section.
- the light emitted to the surroundings via the front can be perceived as white light.
- the back surface geometry may have little to no impact on the perceived light from the light emitting cover portion. As a result, a homogeneous light emission can be achieved in the light-emitting cover section.
- the reflective element Due to the fact that the reflective element is colored, light coming from the light coupling point can be colored on the rear side of the light-emitting cover section in accordance with the color of the reflective element.
- the person skilled in the art also reads that the resulting wavelength of the light emitted to the surroundings via the front side depends not only on the color of the reflecting element, but also on the wave spectrum of the light coupled in at the light coupling point and on other factors. From the above it follows for the person skilled in the art that, depending on the application, combinations of differently designed reflecting elements are also conceivable.
- the light-guiding element and the reflecting element can have plastic or be made of plastic, with the plastic preferably being able to have polycarbonate.
- the light-guiding element and the reflective element must be made of a transparent, but at least translucent, material.
- the use of plastic for the light-guiding element and the reflective element has the advantage over glass, for example, that manufacturing costs and weight can be saved. Furthermore, the inherent security of the wall charging station against external forces can be minimized.
- polycarbonate has the advantage that polycarbonate can be easily processed using the methods customary for thermoplastics, which means that rational, cost-saving series production for medium to large quantities can be made possible. Furthermore, polycarbonates have relatively high strength, impact strength, rigidity and hardness, which means that their use as the material for the light-guiding element and the reflective element brings additional advantages. Also are Polycarbonates are good insulators when it comes to electrical current, so this can also have an advantageous effect in connection with a wall charging station.
- the light-guiding element and the reflective element can be produced from an injection molding process.
- an injection molding process a cost-effective, simple and easily reproducible production of the light-guiding element and the reflecting element can be guaranteed. This allows these components to be easily manufactured as platform products.
- the light-guiding element and the reflecting element can be produced as a two-component plastic part.
- a clear, simple and secure component connection of the light-guiding element to the reflecting element can be ensured in this way.
- this can prevent moisture from penetrating between the light-guiding element and the reflecting element in the area of the rear side of the light-emitting cover section, which could lead to the light-emitting cover section going blind.
- the light-conducting part of the wall charging station can also have a protective and sealing function for the electronic components present inside the wall charging station.
- the production of the light guide element and the reflective element as a two-component plastic part makes it possible to provide these two parts with different or conflicting functional requirements for the individual material components as a single composite part.
- two materials are combined with each other, for example a transparent material and an opaque material with different hardnesses, this is referred to as two-component or 2K applications.
- 2K stands for "two components" (e.g.: hard / soft), which are connected to each other in the injection molding tool.
- the desired connection/adhesion properties of the different materials can be achieved by selecting a suitable material and appropriate geometric design of the adhesive surface in the injection molding tool.
- a major advantage of 2K injection molding is the processing of both materials in an identical manufacturing process. Reworking or assembly of the two components is therefore not necessary. As a result, different materials for the light-guiding element and the reflective element can be implemented in one manufacturing process.
- the light coupling point can be formed essentially parallel to a center plane of the light-emitting cover section.
- the middle plane of the light-emitting cover section can extend, for example, along or parallel to the center plane of a front side of the cover. Due to the fact that the light coupling point is formed essentially parallel to a central plane of the light-emitting cover section, the light-guiding element can have essentially parallel boundary surfaces. As a result, the production of the light-guiding element can be simplified considerably. In addition, this allows the light guide element to be easily integrated into a conventional wall charging station.
- the light guide element can comprise a curved light guide which is designed and set up to guide light from the light coupling point into the light-emitting cover section.
- a curved light guide By using a curved light guide, light from this light source can be coupled into the light coupling point of the light guide element and guided to the light-emitting cover section, regardless of the position of a light source within the wall charging station.
- this allows the light coupling point to be arranged in a simple manner outside and behind the back of the light-emitting cover section.
- the light guide element can be fastened in the cover of the wall charging station.
- the rear side of the light-emitting cover section can be convex or concave relative to the front side of the light-emitting cover section.
- coupled-in light coming from the light-coupling point can impinge on the rear side at an angle of incidence that is greater than the critical angle of total reflection. In this way, coupled-in light can be emitted as perceptible light to the environment via a reflection on the rear side of the light-emitting cover section via the front side thereof.
- the rear side of the light-emitting cover section can have a grating, in which case the grating can preferably be a diagonal grating. Due to the presence of a grating on the back of the light-emitting cover section, a uniform and largely complete reflection and/or scattering of coupled-in light on the back can be achieved in an efficient manner. Furthermore, increased stability of the light-emitting through the grid Cover section can be achieved.
- the grid can be introduced into the light-emitting cover section both in the form of bulges and in the form of indentations.
- the design of the grating as a diagonal grating has the advantage that when light coupled in via the light coupling point enters the light-emitting cover section from the side, this light is more likely to strike a grating strut compared to a vertically arranged grating.
- the wall charging station can also include a printed circuit board with lighting means, wherein the lighting means can be designed and set up to couple light into the light coupling point of the light element.
- the circuit board can be embodied as a printed circuit board, printed circuit board, PCB.
- an already existing printed circuit board of a conventional wall charging station can be supplemented with light sources and thus be fundamentally suitable for being combined with a cover with a light-guiding element according to the present disclosure. This means that conventional wall charging stations can easily be converted to wall charging stations according to the present disclosure.
- the light source can have one or more LEDs.
- the light source can be integrated into the printed circuit board, as a result of which the complexity of the cover can be further reduced due to the reduction in components.
- the light-emitting cover section can also include a display section that is designed and set up to be fully or partially illuminated by means of lighting means arranged on the printed circuit board. Accordingly, the display section can be backlit in a conventional manner by means of lighting means arranged on the printed circuit board. In this way, an additional, illuminated display that is independent of the light-emitting cover section can be provided, via which information can be transmitted to the user of the wall charging station.
- the display section may include a progress bar that displays the progress of a charging process of an electric vehicle connected to the wall charging station.
- the display section can be designed and set up, for example, to display status information for authorizing a user of the wall charging station.
- the display section can be designed and set up to provide information about the device status of the charging station. For example, the charging process with the wall charging station can be explained and carried out simply, clearly and safely.
- the wall charging station can be designed and set up, for example, to display information about an illuminated display section to a user or potential user of the wall charging station initially only via the display section. From the illuminated display section, the user or potential user can deduce, for example, that the wall charging station is basically operational. Furthermore, the wall charging station can be designed and set up to supply the light-emitting cover section with light via the light coupling point only when, for example, a user has been successfully authorized. In this way, light-based communication with a user of the wall charging station can be implemented.
- the cover of the wall charging station can be designed as a half-shell and have fastening means for fastening the cover to a wall-side housing part.
- wall charging stations of conventional design that have already been manufactured, sold and/or already installed on a wall can be easily converted into a wall charging station according to the present disclosure.
- This avoids the disposal of wall charging stations of conventional design, which means that waste production and environmental pollution can be reduced.
- this makes it possible to separate the wall-side housing part and the cover from one another.
- housings and interchangeable adapters that are to be disposed of can be fed to the respective waste treatment processes in a simple manner.
- the light-guiding element and/or the cover can be designed and set up in such a way that the light-guiding element is detachably arranged in the cover.
- This has the advantage that the light-guiding element can be customer-specific and/or application-specific. Nevertheless, this makes it possible to replace or exchange the light-guiding element at any time in a wall charging station that has already been manufactured, sold and/or already installed. In this way, wall charging stations can be used multiple times and in different application areas and/or different ownership situations, in particular if a logo is to be displayed in the light-emitting cover section. As a result, waste production and environmental pollution can be reduced. Furthermore, this makes it possible for the wall-side housing part and separate the cover. Furthermore, this makes it possible, for example, to feed covers and light guide elements that are to be disposed of to the respective waste treatment processes in a simple manner.
- the cover of the wall charging station can also include an opaque cover section. It is advantageous here that conventional opaque materials can be used for the opaque cover section, in particular plastic materials. Manufacturing costs can be reduced as a result. A further advantage is that only the light-emitting cover section or the light-guiding element that can be seen from the outside is optically visible, with the electrical components arranged inside the wall charging station not being visible to the eye.
- each of the opaque cover portion, the light guide element and the reflective element can be made of a three-component plastic part.
- This has the advantage that the entire cover of the wall charging station can be designed as a single component.
- the cover of the wall charging station can fulfill a sealing function for the electrical components arranged inside the wall charging station. At the same time, this can significantly improve the structural stability of the wall charging station cover.
- the same advantages and principles apply to the production of the three-component plastic part as to the advantages and principles previously described in connection with the two-component base material part.
