Abstract

The invention relates to a construction vehicle ( 1 ).
A battery module ( 40; 240; 340 ) is provided to supply electricity to at least one electric motor ( 80, 87 ) of the construction vehicle ( 1 ).
A fastening structure ( 70; 270 ) of the battery module ( 40; 240; 340 ) is designed to be removably fastened to a first longitudinal member ( 10 - 1 ), in a fastening position located beneath the cab ( 29 ) in the vertical direction (C-C) of the construction vehicle ( 1 ), and the battery module ( 40; 240; 340 ) in the fastening position is accessible from an outer side of the construction vehicle ( 1 ) so that said module can be brought into or out of the fastening position from the outer side of the construction vehicle ( 1 ).

First claim

The invention claimed is:

1 . A construction vehicle comprising:
a chassis including
a first longitudinal member and a second longitudinal member, the first longitudinal member and the second longitudinal member being parallel to each other and extending parallel to a longitudinal direction of the construction vehicle, and
a front axle and a rear axle spaced apart in the longitudinal direction of the construction vehicle;
a lifting arm extending parallel to the longitudinal direction of the construction vehicle, the lifting arm being articulated with the longitudinal members between the two longitudinal members so as to be pivotable relative to the longitudinal members about a pivot axis extending in a transverse direction of the construction vehicle that is perpendicular to the longitudinal direction of the construction vehicle; at least one electric motor for one or more of propelling the chassis and driving the lifting arm; a cab for an operator of the construction vehicle, the cab projecting from the first longitudinal member in the transverse direction of the construction vehicle in a direction away from the second longitudinal member, the cab being arranged in a static manner between the front axle and the rear axle in the longitudinal direction of the construction vehicle; and a battery module for supplying electricity to the at least one electric motor, the battery module including
a fastening structure designed to be removably fastened to the first longitudinal member, in a fastening position located beneath the cab in a vertical direction of the construction vehicle that is perpendicular to the longitudinal direction and to the transverse direction of the construction vehicle,
wherein the battery module in the fastening position is accessible from an outer side of the construction vehicle so that the battery module can be brought into or out of the fastening position from the outer side of the construction vehicle, the outer side of the construction vehicle being oriented in the transverse direction of the construction vehicle.

2 . The construction vehicle of claim 1 , wherein the fastening structure includes a profiled element that is removably fastened at both ends thereof directly to the first longitudinal member.

3 . The construction vehicle of claim 2 , wherein the first longitudinal member includes at least one stop that is located beneath the profiled element in the vertical direction of the construction vehicle and on which the profiled element rests when fastened to the first longitudinal member.

4 . The construction vehicle of claim 1 , further comprising two retaining plates projecting from the first longitudinal member, the two retaining plates being located beneath the cab and extending in the vertical direction and the transverse direction the construction vehicle and being spaced apart from one another in the longitudinal direction of the construction vehicle,
wherein the fastening structure includes two fastening plates, each of the two fastening plates being removably fastened to one of the retaining plates.

5 . The construction vehicle of claim 4 , wherein the battery module further includes two guide elements, each guide element being intended to cooperate with an upper end of one of the retaining plates so as to guide the battery module towards the fastening position in a translational movement parallel to the transverse direction of the construction vehicle.

6 . The construction vehicle of claim 1 , wherein
the construction vehicle further includes two fastening arms projecting from the first longitudinal member, the two fastening arms extending beneath the cab in the transverse direction of the construction vehicle and being spaced apart from one another in the longitudinal direction of the construction vehicle, the fastening structure includes two fastening portions, and each of the two fastening arms has a fork, each of the fastening portions being removably fastened to one of the forks.

7 . The construction vehicle of claim 6 , wherein
at least one of the forks has a sliding surface extending in the vertical direction and the longitudinal direction of the construction vehicle, and at least one of the fastening portions is designed to slide on the sliding surface in a translational movement parallel to the vertical direction into the fastening position.

8 . The construction vehicle of claim 7 , wherein at least one of the fastening portions includes a sliding element made of one or more of polymer and rubber for sliding on the sliding surface.

9 . The construction vehicle of claim 6 , wherein the battery module extends in part beneath a space between the longitudinal members.

10 . The construction vehicle of claim 6 , wherein at least one of the two fastening arms supports the cab.

11 . The construction vehicle of claim 1 , wherein a power distribution box is electrically connected to the at least one electric motor, and the battery module includes a single power output socket electrically connectable to the power distribution box.

12 . The construction vehicle of claim 11 , wherein the battery module includes
a base plate, the fastening structure being rigidly connected to or supporting the base plate, at least two battery elements resting on an upper face of the base plate, in the vertical direction, and at least one electrical connection box electrically connected to the battery elements, the electrical connection box including a power output socket electrically connectable to the power distribution box.

13 . The construction vehicle of claim 12 , wherein
the battery module has separator plates separating the battery elements and to which the battery elements are fastened via removable fastening elements, and the removable fastening elements and the separator are electrically conductive, the separator plates being electrically connected to each other and to the battery elements to form a common electrical ground for the battery elements.

14 . The construction vehicle of claim 11 , wherein the power distribution box includes a charging socket for charging the battery module.

15 . The construction vehicle of claim 1 , wherein
the battery module further includes a fairing, the fairing facing away from the construction vehicle in the transverse direction in the fastening position of the battery module, and the fairing has one or more steps enabling the operator of the construction vehicle to access the cab.

16 . The construction vehicle of claim 14 , further comprising a charging cable, the charging cable being electrically connectable to the charging socket, and wherein a fairing has a hatch allowing access to a compartment dimensioned to contain the charging cable.
