Description

The invention relates to a device for producing an electrical connection between two parts pivotable relative to each other about an axis, in particular vehicle parts.

Parts that are pivotally movable relative to one another and between which an electrical connection to the power supply is necessary can be found in all areas of technology.

The term vehicle parts includes both motor vehicles and commercial vehicles as well as other land, sea or air vehicles. Vehicles of the aforementioned type require at a variety of different points a power connector for connecting various terminals, such. Headlamps, rear window heaters, windscreen wipers and the like. Since the vehicles have a plurality of mutually pivotally movable vehicle parts, they must be reliably bridged by an electrical connection, so that in the desired areas a power connection is available.

In the case of motor vehicles or commercial vehicles, the parts of the vehicle which are pivotally movable relative to one another are generally the vehicle frame, to which a plurality of different vehicle parts can be pivoted. This may be, for example, the tailgate (in one or two-part design), the doors, loading openings or the hood act. In particular, when the two mutually pivotally movable vehicle parts are designed as a vehicle frame and a tailgate, particularly high demands are placed on the electrical connection between these two vehicle parts, as must be operated via the electrical connection terminals that have a high power consumption, such as Rear window heating, the taillights or a windshield wiper. In addition, the electrical connection also serves to provide an attached to the tailgate interior lighting with electricity.

The mentioned end users are generally operated and controlled independently of each other, so that a large number of individual connections is necessary.

From the general state of the art, it is known to arrange a free-running cable harness between a vehicle frame and a tailgate, which is allowed to play so much that both a complete opening and a closing of the tailgate is possible. The disadvantage here is that the harness is bent or kinked by the continuous opening and closing operation of the tailgate. To make matters worse, that this takes place even at relatively low temperatures, so that the functionality is not reliably guaranteed over the entire life of the vehicle. In addition, there is always the danger that the cable harness will be torn out or damaged by an accidental hooking due to the play that the cable harness must inevitably have.

From the US 3,659,063 is a hinge between a building door and a frame known, with power contacts in the hinge parts an electrical connection to the door is made to reach by an electrical pulse locking the door.

The present invention is therefore based on the object to provide a device for establishing an electrical connection between two pivotable about an axis to each other moving parts, which ensures a reliable and cost-effective electrical connection.

According to the invention this object is achieved by the characterizing part of claim 1.

By arranging a current transmitter unit and a Stromnehmerseinheit in the region of the axis about which the moving parts are pivoted, can be easily achieved that contact the current transmitter unit and the Stromnehmerereinheit reliably at least in an end position of the pivotal movement of the parts. Manufacturing tolerances or gap dimensions have no negative impact on the contactability of the power supply unit with the Stromnehmerereinheit.

A cable harness for bridging the two mutually pivotable, moving parts is therefore no longer necessary.

Due to the frictional movement of the two units together during the closing and releasing event any dirt, deposits and the like are abraded by the contacts, so that a reliable contact is achieved in the final position. In an advantageous way For this purpose, the contact elements each have a surface formed as a flat contacts.

In a non-obvious manner, the inventor has also recognized that, for example, in a design of the first part as the vehicle frame and the second part as a tailgate, a release of the power supply unit of the Stromnehmereinheit during the opening process is completely unproblematic, since the consumer, for example, a rear window heating, a rear wiper or the taillights, in the open state of the tailgate need no power. Without loss of comfort, it is therefore possible to separate the electrical connection between the two vehicle parts. When closing the tailgate, the Stromnehmerereinheit contacted again with the power supply unit, so that the consumers are supplied accordingly. The arrangement of the current generator unit and the Stromnehmerereinheit is not limited to the area of the axis of the pivot joint, for example, a hinge. Rather, the current transmitter unit and the current receiver unit can be arranged at any point along the theoretical axis of rotation.

It is advantageous that manufacturing and use-related tolerances of the distance between the tailgate and the vehicle frame in the closed state have no negative effect on the contacting of the power transmitter unit with the Stromnehmerereinheit, since the distance between the tailgate and the vehicle frame in the axis in general regardless of tolerances.

It is advantageous if the mutually pivotable parts are connected by means of at least one hinge and the Current transmitter unit and the Stromnehmereinheit are each arranged on a hinge half.

An arrangement of the current transmitter unit and the Stromnehmereinheit on each hinge half of the hinge has been found to be particularly suitable. The pivoting movement of the parts relative to one another is essentially predetermined by the hinges, so that the parts in the region of the hinges also close particularly accurately. By not making any actual changes to the parts, such as Holes for brackets and the like, must be made, the current generator unit and the Stromnehmerereinheit in a simple manner, even subsequently, use to establish an electrical connection between the parts.

In a structural embodiment of the invention can be provided that the current generator unit and / or the Stromnehmerereinheit are connected by means of a dovetail connection with the respective hinge half.

Such a compound is stable, structurally simple to perform and inexpensive. In addition, a replacement of the power transmitter unit or the Stromnehmerereinheit for repair in a simple manner possible.

In a further development of the invention, it can be provided that the surfaces of the contact elements of the current generator unit and / or the current-carrying unit designed as flat contacts have a concave or outwardly curved shape.

Due to the pivotal movement of the moving parts, to which the current transmitter unit and / or the current unit are attached directly or via the hinges, contact the current transmitter unit and the Stromnehmerereinheit by means of a sequence of movements, which usually corresponds to a circular arc (ie radially to each other). Due to the concave shape of the contact elements, or the flat contacts of the current transmitter unit and / or the Stromnehmerereinheit is achieved that the flat contacts before reaching the end position to grind or rub against each other and thereby rub off dirt, deposits and the like.

It is advantageous if the contact elements in the current generator unit and / or the Stromnehmerereinheit are resiliently, or resiliently mounted.

As a result, it is possible for the contact elements of the current generator unit or the current-carrying unit to be able to escape in the printing direction during the grinding or rubbing process if necessary. Damage to the contact elements is thus avoided while ensuring at the same time that a cleaning friction between the contact elements, or the flat contacts is present. For elastic mounting, the contact elements may be arranged at their rear sides remote from the flat contacts in an elastic layer, for example made of rubber or silicone. The elastic layer allows defined deflection or retraction of the contact elements. Preferably, the contact elements are elastically supported independently of each other. For this purpose, for example, the storage of the contact elements may be provided on a silicone pad.

Alternatively or additionally, it can also be provided that the contact elements of the current transmitter unit and / or the Stromnehmerereinheit are mounted in an at least partially elastic wall of the associated power supply unit or the Stromnehmerereinheit.

The arrangement in an at least partially elastic wall also allows a deflection of the contact elements when the pressure exceeds a predetermined amount. It is also advantageous that the individual contact elements are thus movable independently of each other, whereby it is ensured that each contact element unaffected contacted by the other contact elements with the intended contact element of the other unit. A particularly advantageous embodiment of the elastic wall results from the DE 199 30 642 ,

Advantageous developments and refinements of the invention emerge from the further subclaims.

A hinge with means for connecting a current transmitter unit and a Stromnehmerereinheit according to one of claims 1 to 16 results from claim 17.

Hereinafter, a preferred embodiment is illustrated with reference to the drawing.

As can be seen from FIGS. 1 to 6, the device according to the invention for producing an electrical connection has a current transmitter unit 1 and a current receiver unit 2. The current generator unit 1 is arranged on a first vehicle part 3 and the power receiver unit 2 on a second vehicle part 4. The two vehicle parts 3, 4 are indicated in principle in FIG. 2. This may, for example, in the first vehicle part 3 to the frame of a vehicle, not shown, 1n. The second vehicle part 4 may be formed, for example, as a tailgate of a vehicle.

Since the specific design of the vehicle parts for the execution of the invention is not essential, has been dispensed with a detailed illustration in this regard.

The illustrated device according to the invention is not limited to vehicle parts. Rather, the solution according to the invention can be used in all areas of technology.

The current generator unit 1 and the current receiving unit 2 are arranged in the region of an axis 5 about which the vehicle parts 3, 4 are pivotally movable relative to one another.

In the illustrated embodiment, the current generator unit 1 and the Stromnehmereinheit 2 are arranged on a hinge 6. The current generator unit 1 and the Stromnehmereinheit 2 are each arranged on a hinge half 7a, 7b. The hinge halves 7a, 7b are separated by the axis of the hinge 6. The axis of the hinge 6 thus corresponds to the axis 5, by which the vehicle parts 3, 4 are mutually pivotable.

In the exemplary embodiment, the current generator unit 1 and the Stromnehmereinheit 2 are indeed arranged on the hinge 6, but the invention is not limited thereto. The current generator unit 1 and the current-carrying unit 2 can be arranged at any point along a theoretical axis about which the vehicle parts 3, 4 are pivotable relative to each other. An actual rotary or pivot axis does not have to be present for this purpose; the arrangement of the current transmitter unit 1 or of the current receiver unit 2 along a theoretical pivot axis about which the vehicle parts 3, 4 are pivotable is sufficient.

As is apparent from Fig. 1, contact the power transmitter unit 1 and the Stromnehmereinheit 2 in an end position of the pivotal movement of the vehicle parts 3, 4. This may, for example, be a position in which the tailgate of the vehicle is closed. This may be a one-piece or two-piece tailgate.

In the exemplary embodiment, it is provided that the current generator unit 1 and the Stromnehmereinheit 2 by means of a Dovetail connection 8, 9 are connected to the respective hinge half 7a, 7b.

As shown in the embodiment of FIG. 3, while the hinge half 7b for connection to the Stromnehmereinheit 2 a dovetail-like projection 9a. The current receiving unit 2 has a dovetail receptacle 9b corresponding thereto. Similarly, as shown in Fig. 5, the hinge half 7a, which is provided for the arrangement of the current generator unit 1, provided with a dovetail-like projection 8a. For this purpose, the current generator unit 1 has a corresponding dovetail-shaped receptacle 8b, so that a dovetail connection 8 is formed between the current generator unit 1 and the hinge half 7a.

The arrangement of the current generator unit 1 or the Stromnehmereinheit 2 on the hinge 6 is thus possible in a simple manner. If necessary, the compound can be solved in just as simple manner again. In order to prevent the current generator unit 1 or the Stromnehmerereinheit 2 is accidentally released, an additional fixation means of a screw or the like, not shown, may be provided.

2 shows contact elements 1a of the current transmitter unit 1 and (dashed) contact elements 2a of the current receiving unit 2. The contact elements 1a, 2a each have a surface configured as a flat contact 1b, 2b for contacting. The contact elements 1a and 2a are arranged such that these, or their flat contacts 1b, 2b contact each other in the end position shown in Fig. 1. The contact elements 1a and 2a are described in more detail below.

The current transmitter unit 1 has a dovetail receptacle 10 on its rear side facing away from the flat contacts 1b. The dovetail receptacle 10 is shown in FIG. 3 and FIG. 8. In Fig. 1 and Fig. 2, the dovetail receptacle 10 is shown by dashed lines. The dovetail receptacle 10 is in alignment with a dovetail receptacle 11 of the hinge half 7a. This dovetail receptacle 11 is shown in FIGS. 4 and 13. Fig. 1 and Fig. 2 also show the dovetail receptacle 11 by dashed lines. The dovetail receptacle 10 is used in conjunction with the dovetail receptacle 11 for fixing the current generator unit 1 on the hinge half 7a. For this purpose, as shown in Fig. 2, a rear wall, or a fixing plate 12 is inserted into the dovetail receptacle 10 and the dovetail receptacle 11. The fixing plate 12 thus penetrates both the dovetail receptacle 10 of the current generator unit 1 and the dovetail receptacle 11 of the hinge half 7a. By the fixing plate 12 and the dovetail receptacles 10, 11, the dovetail connection 8 between the power supply unit 1 and the hinge half 7a can no longer be solved.

The fixing plate 12 allows a fixation of the current generator unit 1, without holes that would limit the interior of the current generator unit 1, are necessary.

The current generator unit 1 and the current receiving unit 2 may each have a plastic housing. The contact elements 1 a and 2 a are arranged in the current transmitter unit 1 or the power unit 2 and / or with respect to their shape such that the flat contacts 1 a, 1 b of the contact elements 1 a, 2 a rub against each other before reaching the end position shown in FIG.

2 shows a preferred embodiment of the contact elements 1a and the contact elements 2a. 9 shows a section through a preferred embodiment of a current transmitter unit 1 with contact elements 1a.

As is apparent from FIGS. 2 and 9, the flat contacts 1 b of the contact elements 1 a in a preferred embodiment have a concave or outwardly curved shape. Alternatively or additionally, the flat contacts 2b of the contact elements 2a of the current receiving unit 2 may also have a concave shape. The concave shape causes contacting of the contact elements 1a, 2a, before the end position is reached. Thus, the flat contacts 1b, 2b are cleaned from any contamination or coverings.

In the embodiment of the current generator unit 1, which is preferably shown in FIG. 9, it is provided that the contact elements 1a are mounted elastically. For this purpose, the current generator unit 1 has an elastic layer 13, for example made of silicone or rubber, which is arranged on the rear side facing away from the flat contacts 1b of the contact elements 1a. The elastic layer 13 makes it possible for the contact elements 1a to retreat in the direction of the elastic layer 13 from a certain pressure resulting from the contact with the contact elements 2a. Damage to the contact elements 1a is thus avoided.

Alternatively or in addition to the elastic mounting of the contact elements 1a and the contact elements 2a may be mounted elastically. However, an elastic mounting of the contact elements 1a is sufficient.

As an alternative to the fact that the flat contacts 1 b have a concave shape, it can also be provided that the current generator unit 1 or, if appropriate, the current receiving unit 2 have a concave surface into which the flat contacts 1 b or optionally the flat contacts 2 b are embedded.

In another embodiment, not shown, it may also be provided that the contact elements 1a, 2a of the current transmitter unit 1 or the current-carrying unit 2 are mounted in an at least partially elastic wall of the associated current transmitter unit 1 or the current-carrying unit 2. The contact elements 1a, 2a can be poured into the at least partially elastic wall or liquid-tight. The at least partially elastic wall may be formed, for example, as a plastic membrane. A particularly preferred embodiment of this results from the DE 199 30 642 to which reference is made in this regard.

As can be seen from FIG. 9 in conjunction with FIG. 7, the contact elements 1a are each connected to leads 14 which lead to a current source, not shown.

As can be seen from the drawing, the current transmitter unit 1 in the exemplary embodiment has three contact elements 1a. The current receiving unit 2 has correspondingly also three contact elements 2a. Of course, any other number of contact elements 1a, 2a is possible for this purpose. The contact elements 1a, 2a can serve, for example, for supplying a rear window heater, a rear window wiper and rear lights.

As can be seen from FIGS. 1, 2 and in particular FIG. 10, the current-carrying unit 2 has a radius at least partially encompassing the axis 5 of the hinge 6. This results in a particularly advantageous connection of the contact elements 2a with the contact elements 1a.

FIG. 11 shows the dovetail receptacle 9b of the current-carrying unit 2 for connection to the dovetail-like projection 9a of the hinge half 7b.

FIG. 12 shows the contact elements 2 a, which, analogous to the contact elements 1 a, have flat contacts 2 b having a substantially rectangular shape. The contact elements 2a are each connected to a line 15 which leads to a consumer.

FIGS. 13 to 17 show the hinge 6 with means for connecting the current generator unit 1 and the current receiving unit 2 in detail.

As can be seen from FIG. 13, the two hinge halves 7a, 7b have recesses 17, by means of which the supply lines 14 to the current transmitter unit 1 or in a simple manner are provided. the lines 15 can be performed by the Stromnehmereinheit 2 to a consumer. FIG. 13 further shows the dovetail receptacle 11, which, as already described, is provided for fixing with the fixing plate 12. Such a dovetail receptacle 11 can also be provided for fixing the current-carrying unit 2 in the hinge half 7b.

The dovetail receptacle 11 extends, as can be seen from a combination of FIG. 13 with FIG. 14, at an angle of 90 ° to the dovetail-like projection 8a.

From Figs. 13 and 14, and in detail in Figs. 16 and 17, a single contact element 16 for establishing an electrical connection between the two hinge halves 7a, 7b can be seen. The individual contact element 16 is arranged on the axis 5. In the exemplary embodiment, it is provided that the individual contact element as a spring washer 16, as shown in Fig. 16 and Fig. 17, is formed. The spring washer 16 serves to transmit a low-voltage voltage from the hinge half 7a to the hinge half 7b. Advantageously, this makes it possible, even in the open state of the hinge 6, i. if the contact elements 1a are not in contact with the contact elements 2a, to transmit a voltage. The spring washer 16 can be used, for example, to supply an interior lighting.

The current generator unit 1 or the current receiving unit 2 can in an alternative embodiment with a magnetic Trigger device be provided.
