Description

The invention relates to a light assembly for an electric motor vehicle and an electric motor vehicle. The invention particularly relates to a rear light assembly for an electric motor vehicle.

Electric vehicles usually have an electrical energy storage device such as a high-voltage storage device in order to provide the electrical energy required to propel the electric vehicle. The energy store can be charged by means of a charging plug via a charging socket that is connected to the energy store via a cable.

Charging sockets are known from the prior art, which are arranged in an opening in the body of the electric motor vehicle. In order to prevent the penetration of moisture and / or liquids, these charging sockets are sealed both at the passage opening to the outer body skin and at the opening to the inner body skin. The assembly is therefore carried out according to a wet-dry-wet concept on the body of the electric vehicle.

This solution, however, leads to a great deal of assembly work, since the charging socket has to be sealed on two levels, and a great deal of security work to ensure that the seal between the outer and inner skin of the body is actually tight.

It is therefore the object of the invention to enable a simplified assembly of the charging socket.

According to the invention, this is achieved by a light assembly for an electric motor vehicle, which has a housing and a charging socket. The housing delimits a first chamber and at least one further second chamber. The first chamber represents a wet area and the charging socket is at least partially arranged in the first chamber.

The invention is based on the basic idea of integrating the charging socket into the light assembly and arranging it in an area of the light assembly which is arranged in the wet area in the installation position on the electric motor vehicle. This means that no breakthrough into the dry area is necessary and the installation of the charging socket is simplified.

For example, a charging coupling of the charging socket is arranged in the first chamber.

In general, it is also conceivable that the charging socket is arranged completely in the first chamber.

The light assembly is in particular a rear light assembly, that is, a light assembly for the rear of the electric motor vehicle. Tail light assemblies are also known as tail lights or tail lights. In general, it is also conceivable that the rear light assembly is part of the rear light or rear light.

The light assembly has light elements or lighting means, for example LEDs, by means of which a driving state of the electric motor vehicle can be displayed and / or which are used to illuminate the vehicle.

A light element or illuminant can be arranged in the first chamber of the electric motor vehicle.

The wet area is also known as a wet room, i.e. an area that is in direct contact with the surroundings of the electric vehicle. In particular, the wet room is not sealed off from liquids acting from outside the electric motor vehicle.

In contrast, the dry area is sealed off from the surroundings of the electric motor vehicle. In particular, no liquid can penetrate into the drying area from the outside. The drying area is also known as the drying room.

An electric motor vehicle is understood to mean a motor vehicle for the transport of people or goods that has an electrical energy store that is connected to an electric motor used to drive the electric motor vehicle. The energy storage device is charged via a charging socket on the electric vehicle.

For example, the electric motor vehicle is a purely electrically driven motor vehicle or a hybrid electric motor vehicle.

The purely electrically driven motor vehicle can additionally have a fuel cell and a fuel cell tank, so that electrical energy is provided both by the energy store and by the fuel cell.

One aspect of the invention provides that the at least one second chamber is sealed off from the first chamber, in particular wherein the second chamber represents a dry area.

In other words, the light assembly is divided into a dry area and a wet area. Thus, components can also be provided in the housing of the light assembly, for example electronics for controlling the Luminous elements that must be protected from liquids.

The housing can have a lamp pot and an at least partially transparent lamp cover. In this way, the housing is formed from a few components.

For example, the charging socket is integrated into the lamp pot.

In one embodiment of the invention, the lamp cover has a first section which is assigned to the first chamber and which can be pivoted between an open and a closed position relative to the lamp pot. Thus, the first chamber and thus the charging socket are easily accessible.

For example, in the closed position, the first section of the lamp cover seals off a charging coupling of the charging socket. The charging plug can therefore simply be inserted into the charging coupling.

The lamp cover can have a second section which is assigned to the second chamber and which is fastened to the lamp assembly in a fixed manner opposite the lamp pot, in particular the second section sealing off the second chamber.

In other words, the lamp cover cannot be pivoted in the second section, that is to say in the area of the second chamber. The lamp cover seals the second chamber from the outside. In this way, a compact design of the light assembly is made possible.

The object of the invention is also achieved by an electric motor vehicle which has a body and a previously described lamp assembly fastened to the body. With regard to the advantages and features, reference is made to the preceding statements on the light assembly, which apply equally to the electric motor vehicle and vice versa.

In one embodiment of the invention, the light cover extends on two sides of the body, in particular on a rear side and a longitudinal side of the body.

In other words, the light assembly extends on two sides of the electric motor vehicle. In this way, good visibility of the light signals provided by the light assembly is ensured.

The first chamber can be arranged in a region of the light assembly that extends on one of the longitudinal sides of the body.

In other words, a charging plug can be inserted into the charging coupling of the first chamber from one side of the vehicle. The charging stations for charging the energy store of the electric motor vehicle are often arranged on the side of the road, so that the arrangement of the charging coupling on a longitudinal side of the electric motor vehicle enables convenient charging. The charging cable of the charging plug therefore does not have to be routed along different sides of the electric motor vehicle.

In one embodiment of the invention, the electric motor vehicle has a body attachment movably attached to the body, in particular a moveable tailgate, and a lamp device attached to the moveable body attachment. The movable body attachment can be pivoted between an open and a closed position.

In other words, the rear light of the electric motor vehicle is formed by two parts. The movable component can thus extend over essentially the entire length of one side of the electric motor vehicle, in particular over the entire width of the vehicle, and enables convenient access to the area of the electric motor vehicle that is closed by the movable component.

In the closed position of the component, the lighting device can adjoin the lighting assembly attached to the body in the transverse direction of the vehicle. In this way, a large display area of the light signals provided by the rear light is made possible.

In one embodiment of the invention, a cavity is provided on the body that forms a wet area, the first chamber of the light assembly opening into the cavity. The charging socket cavity simplifies the electrical contacting of the charging socket, since the rear side of the charging socket is still accessible in the assembled state and the charging socket can thus be contacted with the high-voltage storage unit via cables in the assembled state.

For example, the cavity is open to the outside in the transverse direction of the electric motor vehicle.

In order to enable a hidden cable routing through the body to the charging socket, the Cavity open into a wheel arch, in particular into a rear wheel arch of the body.

The body can have a battery box, in particular on the underside of the body, and a cable, the cable extending from the battery box to the charging socket. In this way, an energy store arranged in the battery box, for example a high-voltage store, can be charged.

The cable can extend through the cavity. In this way, only a relatively short cable is required to connect the battery box to the charging socket.

For example, the cable routing of the cable is arranged completely in the wet area of the electric motor vehicle. Breakthroughs in the body for cable routing and corresponding seals of the openings are avoided. The assembly effort and also the security effort are thus reduced.

In order to ensure ergonomic insertion of the charging plug into the charging socket, the center of the charging socket can be arranged at a height between 770 mm and 1020 mm of the electric motor vehicle, in particular in a range between 850 mm and 950 mm.

In one embodiment of the invention, the charging socket in the installed position has an angle to the vertical between 5 ° and 20 °, in particular in the range from 10 ° to 15 °. This enables a convenient insertion of a charging plug into the charging coupling of the charging socket.

The electric motor vehicle can have a second, previously described lamp assembly. The features and advantages already explained for the first light assembly result, and vice versa.

The light assemblies can be arranged on opposite sides of the electric vehicle.

In other words, the electric motor vehicle has two charging sockets which are arranged on different longitudinal sides of the electric motor vehicle, so that a charging plug for charging the energy storage device can be inserted into a corresponding charging coupling from two longitudinal sides of the electric motor vehicle.

In this way, the electric motor vehicle can also be charged more quickly by using two charging plugs.

For example, the light assemblies are designed symmetrically to the center plane of the electric motor vehicle in the longitudinal direction of the vehicle.
