The disadvantage of this technical solution is that the extension of the battery box occurs due to the direct sliding of the box with batteries weighing more than 60 kg along metal guides, which requires a lot of effort during installation/dismantling of this box, in addition, the extension of the box occurs partially, and the guides of the battery box are not sufficiently protected from corrosion, which reduces the service life of the extension mechanism.

The task that the claimed technical solution is aimed at solving is the use of a more reliable design for extending the battery box with the ability to extend the box by two battery lengths.

The stated problem is solved in that a pull-out battery box contains a tray with telescopic guides and a handle, where the batteries are secured to the pull-out box using strips, ties and bolts, and the pull-out box is secured to the tray using fixing bolts, wherein the guides are designed with the possibility of being secured with a fixed part to the frame of the vehicle, and the movable part, having cages with balls, is designed with the possibility of extending the tray by two lengths of the batteries.

The set of distinctive features, consisting in the fact that the storage batteries are secured to the pull-out drawer using strips, ties and bolts, and the pull-out drawer is secured to the tray using fixing bolts, while the guides are designed with the possibility of being secured with a fixed part to the frame of the vehicle, and the movable part, having clamps with balls, is designed with the possibility of extending the tray by two lengths of storage batteries, allows the use of a reliable design for extending the battery box by two lengths of storage batteries.

The utility model is illustrated by the following drawings:

Fig. 1 – pull-out drawer for storage batteries, general view from the right in a ¾ angle in the retracted position;

Fig. 2 - the same, remote element A in Fig. 1;

Fig. 3 – the same, general view from a ¾ angle in the extended position;

Fig. 4 - the same, general view from the left, assembled on the frame, at a ¾ angle, with the drawer fully extended.

The drawer for storage batteries comprises a tray 1 with telescopic guides 2. The storage batteries are secured with the drawer using strips 3, ties 4 and bolts 5. The drawer is secured with the tray using fasteners through fixing bolts 6. The front part of the tray 1 has a handle 7. In addition, the guides 2 are designed with the possibility of being secured with a fixed part to the frame of the vehicle, and their movable part is designed with the possibility of extending the tray by two lengths of the storage batteries due to the presence of a clip 8 with balls 9 and holding it in the extended position.

Before pulling out the drawer, it is necessary to remove the tray fasteners from the fixing bolts 6, and using the handle 7, pull out the drawer to the required distance; in this case, pulling out the drawer is not difficult, since pulling out is carried out with the help of guides 2, the sliding of which occurs due to movement along balls 9. When finishing work with batteries, the drawer should be pushed back and the fasteners should be secured with fixing bolts 6.

Thus, the claimed technical solution allows the use of a reliable design for extending the drawer by two battery lengths.

The claimed technical solution meets the requirement of industrial applicability and can be implemented on standard technological equipment using previously mastered technologies.
