SOLAR COLLECTOR FOR ARRANGEMENT IN A PASSENGER CAR

Abstract

A solar collector is provided for detachable arrangement on a parcel shelf of a passenger car. In this way, the solar collector can be used in the vehicle attached to the parcel shelf or outside the vehicle detached from the parcel shelf. When the solar collector is attached to the parcel shelf, electrical devices of the vehicle and external electrical devices can be operated by the solar collector. When the solar collector is disconnected from the parcel shelf, external electrical devices may still be operated by the solar collector. Accordingly, the solar collector presents itself as a mobile component which can be utilized independently of the passenger car.

DETAILED DESCRIPTION

[0024] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description.

[0025] FIG. 1 illustrates a passenger car designed as a station wagon in its rear region, with opened tailgate, thus accessible load compartment 2. The same is covered at the top by a parcel shelf 3. The same is arranged horizontally and on its top side includes a recess for receiving a solar collector 4. The same receives solar cells 5 in the region of the top side. The solar collector 4, as is evident in the representation regarding FIG. 2, is provided, on its side facing the vehicle interior, with three connections 6, 7 for operating external electrical devices 29. The two connections 6 are USB connectors and the connection 7 a usual power connection, thus for connecting an external electrical device such as an electric fan, a lamp, a laptop etc.

[0026] In FIGS. 3 to 6 a first exemplary embodiment of a solar collector 4 is described. The solar collector 4 includes a housing 8 with a top side 9 and a bottom side 10. Here, the specifications top side and bottom side relate to the orientation of the solar collector 4 when lying on the parcel shelf 3. In the region of the top side 9, the solar collector 4 receives the solar cells 5. Between top side 9 and bottom side 10, the housing 8 is provided with a surrounding edge 11. The same is rectangular, with two parallel long edge sides 12 and two parallel short edge sides 13. In the region of the one long edge side 12, namely the one which when the solar collector 4 lies on the parcel shelf 3, faces the vehicle interior, the housing 8 is provided with the connections 6, 7. These connections 6, 7 are arranged symmetrically, wherein the middle connection 7 is arranged in the region of half the length of this long back side 12.

[0027] In the region of the bottom side 10, the housing 8 includes a recess 14 for receiving a plurality, in the exemplary embodiment for receiving four batteries 15 that are rechargeable by means of solar current. The recess 14 with the batteries located therein can be closed by means of a lid 16. On both sides of the lid 16 supports 17 are mounted in the housing 8. These two supports 17 can be pivoted out of the housing 8 so that the solar collector can be positioned on a base with respect to a position that is inclined to the vertical. FIGS. 3 and 4 show the supports 17 in their pivoted-out position, FIGS. 5 and 6 the supports 17 in their position in which they are pivoted into the housing 8.

[0028] In the case of this exemplary embodiment, the batteries 15 are thus recharged via the solar cells 5 and via the batteries 15 and an electronic system that is not illustrated and assigned to the solar collector 4, the external electrical devices operated,

[0029] In FIGS. 7 and 8, a configuration of the solar collector 4 that is modified with respect to the exemplary embodiment according to FIGS. 3 to 6 and a modified connection of solar collector 4 and parcel shelf 3 illustrated. Parts of the two exemplary embodiments which correspond in construction or in the mode of operation are marked with the same reference numbers for the sake of simplicity,

[0030] The exemplary embodiment according to FIGS. 7 and 8 differs from that according to FIGS. 3 to 6 in that the supports 17 cannot only be pivoted out but are also extendable, furthermore in that in the housing 8 attachment 18 for connecting solar collector 4 and parcel shelf 3 are provided, wherein one or a plurality of attachments 18 not only serve for the mechanical connecting but equally for electrically contacting electrical components of the solar collector 4 and electrical components of the parcel shelf 4.

[0031] FIG. 7 illustrates one of the two supports 17 both in a position pivoted into the housing 8, with short configuration of the support 17, and also in the pivoted-out position of the support 17, with extended support 17. For extending the support 17, the same is pivoted about its pivot bearings 19. The respective support 17 includes two parts 20, 21 telescopically arranged. The part 20 in the region of an end accommodates the pivot bearing 19 and in the region of the other end is telescopically inserted into the part 21. By relatively rotating part 20 and 21, a clamping mechanism between the two parts 20, 21 may be released so that these can be moved relative to one another. By rotating back, the clamping mechanism is activated so that the two parts 20, 21 are axially fixed. The length of the support 17 is dimensioned corresponding to the desired angle of inclination of the housing 8 to a base 22.

[0032] As is further evident from the representation of FIG. 7, the housing 8 in the region of its top side 9 includes sliding elements 23 for extending an attachment 18 that is connected to the respective sliding element 23. The respective attachments 18 in the region of the long edge side 12 of the housing 8 is mounted in the same and displaceable relative to the same. Attachments 18 are thus provided on sides of the housing 8 facing away from one another for connecting the solar collector 4 with the parcel shelf 3 in the region of these long edge sides 13.

[0033] FIG. 8 shows the arrangement of solar collector 4 and parcel shelf 3, for the connecting region of a holding means 18, which additionally assumes the task of electrical connecting. Here, the parcel shelf 3 has two plate-shaped sections 24 which are arranged parallel to one another and a function section 25 connecting these sections 24. The housing 8 of the solar collector 4 on the bottom side 10 includes rubber feet 26, which support themselves on a plate-shaped section 24 assigned to these. An attachment 18 arranged in this region is illustrated on the one hand in its position retracted into the housing 8 and furthermore in its position extended from the housing 8. In the extended position, the attachment 18, which is formed as pin or plate, is inserted into a complementary receptacle 27 of the function section 25. In this receptacle 27, an electrical contact 28 (i.e., a +/ contact is inserted and held in the function section 25. The contact 28 constitutes a connection for connecting to an electronic system of the passenger car. In order to establish a conductive connection between the electrical components of the solar collector 4 and this contact 28, the attachment 18 is likewise configured as a current-conducting component that is connectable to the contact 28. The attachment 18 is connected to the electrical components of the solar collector 4.

[0034] Accordingly, when connecting parcel shelf 3 and solar collector 4 direct electrical contacting of the electrical components of the solar collector 4 with the electrical components of the passenger car takes place. This contacting may take place also by way of a plurality, in particular two attachments 18. By way of this electrical contacting a battery of the passenger car 1 can be recharged by the solar collector 4.

[0035] While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing an exemplary embodiment, it being understood that various changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the invention as set forth in the appended claims and their legal equivalents.
