wherein the lock mechanism includes a positioning member and a lever,
wherein the positioning member is provided so as to sandwich the battery in the front-and-rear direction and the vehicle width direction in a state where the battery is mounted on the vehicle body frame,
wherein the lever is used for switching the state of the lock mechanism between the lock state and the release state, and is rotatably provided on the positioning member,
wherein the lever includes a grip portion, a side portion, and a rotating shaft member.
2. The truck according to claim 1 , further comprising:
a front wheel and a rear wheel, wherein
the battery is disposed between a drive shaft of the front wheel and a drive shaft of the rear wheel in the front-and-rear direction of the truck.
3. The truck according to claim 2 , wherein
the electric motor is disposed so as to at least partially overlap one of the front wheel and the rear wheel in side view of the truck, and
the engine is disposed so as to at least partially overlap the other of the front wheel and the rear wheel different from the one of the front wheel and the rear wheel in side view of the truck.
4. The truck according to claim 2 , wherein
the front wheel is driven by at least the electric motor, and
the rear wheel is driven by the front wheel, and
the engine is provided behind the battery in the front-and-rear direction of the truck.
5. The truck according to claim 2 , further comprising:
a control unit that controls at least the electric motor, wherein
the control unit is disposed between the electric motor and the battery in the front-and-rear direction of the truck.
6. The truck according to claim 1 , wherein
the battery is attachable and detachable in an up-and-down direction with respect to the vehicle body frame.
7. The truck according to claim 1 , wherein
a plurality of batteries are provided, and
the plurality of batteries are disposed side by side in a vehicle width direction.
8. The truck according to claim 6 , wherein
the vehicle body frame includes a first portion that supports the electric motor and the battery, and a second portion that supports the engine, and
the second portion is connected to the first portion in a state where an inclination is suppressed by an inclination suppression mechanism that suppresses an inclination of the engine.
9. The truck according to claim 8 , wherein
the engine is provided with an engine stop mechanism that stops drive of the engine when an inclination of the engine exceeds a predetermined threshold.
10. The truck according to claim 1 , wherein
the vehicle body frame includes a mounting portion on which a mounted object is mounted, and
the engine is supported by the vehicle body frame such that an upper end of the engine protrudes upward from an upper end of the mounting portion.
11. The truck according to claim 1 , wherein autonomous traveling is enabled by an autonomous control unit that is mountable on the truck.
12. A truck comprising:
an electric motor that generates a traveling drive force;
a battery that supplies power to the electric motor;
an engine that drives a generator capable of charging the battery;
a lock mechanism that is capable of manually switching between a lock state in which the battery is locked with respect to the vehicle body frame and a release state in which the battery is removable from the vehicle body frame; and
a vehicle body frame that supports the engine, the electric motor, and the battery,
wherein the battery is attachable and detachable with respect to the vehicle body frame,
wherein the battery is provided between the electric motor and the engine in a front-and-rear direction of the truck,
wherein the electric motor, the battery and the engine are disposed on a straight line along the front-and-rear direction of the truck in a plan view,
wherein the lock mechanism includes a lever and a regulation member,
wherein the lever is used for switching the state of the lock mechanism between the lock state and the release state, and is rotatably provided on the positioning member,
wherein the regulation member is a member capable of regulating movement of the battery in an up-and-down direction, and is displaced between a lock position for regulating movement of the battery in the up-and-down direction and a release position for releasing regulation by rotation of the lever,
wherein the regulation member includes an inclined portion that abuts on the side portion of the lever.
13. The truck according to claim 12 , wherein, when the lever rotates from the release state to the lock state, the side portion rotates while abutting on the inclined portion of the regulation member, so that the regulation member is displaced inward in a vehicle width direction of the truck.
14. The truck according to claim 12 , wherein the regulation member is provided so as to be biased to an outside in a vehicle width direction of the truck.
