In addition, among other small-sized electronic components such as the powertrain controller 4, the small-sized electronic components may include, for example, sensors, switching signals, actuators, and the like. The present disclosure is not limited thereto.

Considering that the large-sized components such as the battery pack 2 and the power assembly 3 are heavy and the other small-sized electronic components such as the power assembly controller 4 are light, in some embodiments, referring to fig. 1 to 3, the first installation space 110 may be located below the second installation space 120 in the vertical direction, so that the center of gravity of the unmanned vehicle can be lowered and the stability of the whole vehicle can be improved.

In addition, in some embodiments, referring to fig. 1 to 3, the first opening 130 may be located at the top end of the frame body 1 in the vertical direction, and the second opening 140 may be located at the bottom end of the frame body 1, so that when a field installer completes the installation of components in the installation space on one side, it is possible to turn the frame as a whole and continue to install components in the installation space on the other side, thereby facilitating the installation on the field.

Fig. 1, 3, 5 and 6 exemplarily show that the first frame 5 may be embedded in the first opening 130 and the bottom wall surface of the first frame 5 is coplanar with the bottom end of the frame body 1, the first connection assembly 7 may include a cover structure 710 and a first fastener 720, and the cover structure 710 is detachably pressed on the first frame 5 and the frame body 1 by the first fastener 720, such as a connecting bolt, so that the reliability is high and interference between the first frame 5 and the wheels 10 can be avoided, thereby affecting normal running of the unmanned vehicle.
