Description

Industrial truck having a battery block and an automatically contact-
making coupling/plug connection The invention relates to an industrial truck having a S battery compartment and a battery block which can be moved in the substantially horizontal direction in relation to the battery compartment for the purpose of carrying out a battery change, a coupling/plug connection being provided for the purpose of electrically connecting the battery block to an electrical system of the industrial truck, and a first part of the coupling/plug connection being arranged on the battery compartment and a second part of the coupling/plug connection being arranged on the battery block such that, when the battery block is inserted in the battery compartment, the coupling/plug connection automatically makes contact.
Industrial trucks having a battery block which can be replaced may be in the form of, for example, counterweight fork-lift trucks, reach trucks, reach fork-lift trucks, high-bay stackers, high-bay order pickers, highreach trucks or low-reach trucks. It is known with these industrial trucks to design the battery compartment and the vehicle frame such that the movement of the battery block during a battery change takes place in the horizontal direction. In this case, a roller track is generally arranged on the base of the battery compartment and makes it possible to displace the battery block using relatively little force.
The electrical system of an industrial truck in particular comprises the electric aggregates of a traction drive, of a lift mechanism and of a steering arrangement. The electrical connection between the battery block and the electrical system of the industrial truck is generally made by means of a standardized coupling/plug connection, the coupling of the coupling/plug connection being arranged on the battery block S and the plug of the coupling/plug connection being arranged on the industrial truck. With most of the industrial trucks from the prior art, once the battery block has been inserted in the battery compartment the coupling/plug connector is connected manually by an operator.
Likewise known already are arrangements in which the coupling/plug connection is connected automatically as the battery block is inserted in the battery compartment. In this case, the plug, which is fixedly connected to the battery compartment, and the socket, which is fixedly connected to the battery block, are pushed one inside the other as a result of the insertion movement of the battery block. This requires the battery block to be guided very accurately and particularly low manufacturing tolerances to be maintained for the battery compartment and the battery block.
The present invention is directed to an industrial truck which can be produced with the conventional manufacturing tolerances and in the case of which the coupling/plug connection automatically makes contact when the battery block is inserted.
This invention provides an industrial truck having a battery compartment and a battery block which can be moved in the substantially horizontal direction in relation to the battery compartment for the purpose of carrying out a battery change, a coupling/plug connection being provided for the purpose of electrically connecting the battery block to an electrical system of the industrial truck, and a first part of the coupling/plug connection being arranged on the battery compartment and a second part of the coupling/plug connection being arranged on the battery block such that, when the battery block is inserted in the battery compartment, the coupling/plug connection automatically makes contact, wherein the first part of the coupling/plug connection is arranged fixedly on the battery compartment and the second part of the coupling/plug connection is arranged on the battery block such that it can move, and in that a guide is arranged on the battery compartment for the purpose of guiding the second part of the coupling/plug connection. The battery block itself is guided within the battery compartment using a conventional arrangement, for example by the side walls of the battery compartment.
In an expedient manner, the second part of the coupling/plug connection is arranged on the battery block such that it can move in the vertical direction. This makes it possible to compensate for tolerances as regards the vertical alignment of the two parts of the coupling/plug connection.
It is likewise expedient if the second part of the coupling/plug connection is arranged on the battery block such that it can move in the horizontal direction, perpendicular to the insertion direction of the battery block. This makes it possible to compensate for positional deviations between the two parts of the coupling/plug connection in the lateral direction.
It is made easier to bring the second part of the coupling/plug connection into engagement in the guide if the second part of the coupling/plug connection has a defined neutral position as regards its ability to move in the vertical direction and/or as regards its ability to move in the horizontal direction. If no external forces act on the second part of the coupling/plug connection, it is always in the defined neutral position.
In accordance with one expedient refinement, the second part of the coupling/plug connection is fixed to the battery block by means of at least one spring rod which is aligned substantially parallel to the movement direction of the battery block. The spring rod makes it possible for the second part of the coupling/plug connection to move in all directions perpendicular to the movement direction of the battery block. However, it is not possible for the second part of the coupling/plug connection to move in the longitudinal direction of the spring rod, with the result that the force required to fit together the coupling/plug connection can be transmitted from the battery block via the spring rod to the second part of the coupling/plug connection.
It is particularly expedient if two spring rods are provided which are aligned parallel to one another and which are spaced apart from one another in the horizontal direction, perpendicular to the insertion direction of the battery block. At the end which is spaced apart from the second part of the coupling/plug connection, the two spring rods are rigidly connected to the battery block. The parallel arrangement of the two spring rods makes a rotational movement of the second part of the coupling/plug connection about a vertical axis more difficult, whereas a comparatively lower counterforce opposes a translational lateral deflection.
The second part of the coupling/plug connection is connected in a hinged manner to each spring rod, preferably by means of in each case a ball joint. This ensures that each individual spring rod exerts exclusively translational forces, but no torques, on the second part of the coupling/plug connection.
One expedient embodiment of the invention consists in the guide arranged on the battery compartment having at least one guide rail for the purpose of guiding the second part of the coupling/plug connection in the horizontal and/or in the vertical direction. During the insertion movement of the battery block into the battery compartment, the guide rail guides the second part of the coupling/plug connection until it is inserted, at the end of the insertion movement, in the first part of the coupling/plug connection.
It is expedient here if the guide formed by the at least one guide rail tapers towards the first part of the coupling/plug connection. At the end spaced apart from the first part of the coupling/plug connection, the guide is so wide that, even given maximum manufacturing and positional tolerances for the battery block and the battery compartment, the second part of the coupling/plug connection is in any case moved into the guide at the beginning of the insertion movement. The guide which tapers towards the first part of the coupling/plug connection is designed such that the two parts of the coupling/plug connection are centred with respect to one another shortly before the end of the insertion movement.
The position of the second part of the coupling/plug connection in relation to the guide rail is defined by at least one roller and/or at least one sliding block being arranged on the second part of the coupling/plug connection for the purpose of engaging in the at least one guide rail.
The arrangement according to the invention makes it possible for the coupling and the plug of the coupling/plug connection to be formed by standardized components. No special manufacturing steps are thus required for the coupling and the plug, which are generally provided with plastic housings.
The coupling/plug connection comprises an electrical connector for monitoring the state of charge of the battery block. Besides the two electric lines for the power supply of the industrial truck there is at least one further line for the transmission of signals.
According to an advantageous development of the invention the coupling/plug connection comprises a hose connection for automatically topping up battery cells of the battery block with de-ionised water, the hose connection being automatically contacted when the battery block is inserted in the battery compartment.
Subject of the invention as well is a battery block with a second part of the coupling/plug connection for the use in an industrial truck according as described above.
Another subject of the invention is a guide with a first part of a coupling/plug connection for the use in an industrial truck as described above. This unit of the guide and of the first part of the coupling/plug connection can for example be refitted to industrial trucks. Possible as well is the use of such a unit in a charging station for one or more battery blocks. Then, an automatic contacting of the battery block is also provided in the charging station, when the battery block is inserted in the charging station for being charged.
Further advantages and details of the invention will be explained in more detail with reference to the exemplary embodiment illustrated in the schematic figures, in which: Figure 1 shows part of an industrial truck according to the invention, Figure 2 shows a battery block with the second part of the coupling/plug connection, Figure 3 shows a guide with the first part of the coupling/plug connection, Figure 4 shows a second part of the coupling/plug connection with a hose connection.
Figure 1 shows part of an industrial truck according to the invention in the form of a reach fork-lift truck.
Illustrated is a frame 1 of the industrial truck with wheel arms 2 arranged thereon. Two masts 3, which cannot be extended, of a lifting frame are fixed to the frame 1 and to the wheel arms 2. A battery compartment of the industrial truck, in which a battery block 4 is arranged, is located partly in the interior of the frame 1, partly between the two masts 3 and partly between the two wheel arms 2. At the top, the battery compartment 3 is closed off by a plate, not illustrated in Figure 1 (cf. Figure 3, item 5), of which the upper side forms the base of a driver's platform of the industrial truck. The battery block 4 can be removed in direction 6 from the battery compartment and inserted in the battery compartment again in the opposite direction 7.
The arrangement according to the invention for automatically making contact via a coupling/plug connection 8 is located in the region of the upper side of the battery block 4. The first part 9 of the coupling/plug connection 8 is formed by a plug and is fixed to the plate (cf. Figure 3, item 5). The second part 10, formed by a socket, is fixed to the battery block 4 such that it can move. In the position illustrated in which the two parts 9, 10 of the coupling/plug connection 8 are inserted one inside the other, an electrical connection is produced between the battery block 4 and an electrical system of the industrial truck. In order to make it possible to automatically insert the two parts 9, 10 of the coupling/plug connection 8 one inside the other, the second part 10 is fixed to the battery block 4 such that it can move by means of two spring rods 11. A guide 12, which aligns the second part 10 coaxially with respect to the first part 9 during the insertion movement of the battery block in direction 7, is arranged on the first part 9 of the coupling/plug connection 8.
Figure 2 shows a battery block 4 with the second part 10, formed by a socket, of the coupling/plug connection 8. The figure shows, in particular, how the second part 10 is fixed to the battery block 4 by means of two spring rods 11. The spring rods 11 are fixed rigidly to the battery block 4 at their right-hand (in the drawing) end by means of a clamping apparatus 13. The connection of the spring rods 11 to the second part 10 of the coupling/plug connection 8 is made by means of in each case one ball joint 14. The elastic deformability of the spring rods 11 makes it possible for the second part 10 to move upwards and to the side in relation to the battery block 4. The ball joints 14 ensure that the second part 10 can pivot at least slightly about a horizontal transverse axis and thus make it possible, in particular, to compensate for the angular position of the second part 10. Furthermore, four rollers 15 and two sliding blocks 16 are arranged on the second part, and these are provided for the purpose of engaging in the guide 12 and fix the position of the second part 10 of the coupling/plug connection 8 within the guide in all relevant directions.
Figure 3 shows the guide 12 with the first part 9 of the coupling/plug connection 8, which is formed by a plug. The first part 9 is fixed to the plate 5 which forms the upper side of the battery compartment. The plate 5 at the same time forms part of the guide 12 and defines the position of the second part 10 of the coupling/plug connection 8 at the top. In addition, the guide 12 has two guide rails 17 which guide the second part 10 in the lateral direction and downwards. The guide rails 17 are spaced further apart at the right-hand (in the drawing) end than in the region of the first part 9. Furthermore, the lower sides of the guide - 10 - rails 17 (when viewed from right to left) extend obliquely upwards. This formation makes it easier to insert the second part 10 of the coupling/plug connection 8 in the guide 12 at its right-hand (in the drawing) end, and, as the battery block 4 is inserted, guides the second part 10 into a precisely coaxial position with respect to the first part 9.
Figure 4 shows a second part 1 of a coupling/plug connection 8 with one part of a hose connection 20. When the battery block 4 is inserted in the battery compartment, the shown part of the hose connection 20 is automatically connected with a second part of the hose connection 20 fixed to the industrial truck. The cells of the battery block 4 are automatically topped up with de-ionised water through the hose connection 20 and the hoses connected to it. The second part 10 of the electric coupling/plug connection 10 shows two lines 21 for the power supply of the industrial truck.
A third line 22 serves for the transmission of data, for example referring to the loading condition of the battery block 4.
