Abstract
With continued reference to FIGS. 12, 16, and 17, in other embodiments, the collision side plate 13 is provided with a light transmissive portion 132 at a position corresponding to the obstacle avoidance sensor 61, and the at least one obstacle avoidance sensor 61 is hermetically connected to the collision side plate 13. Here, the obstacle avoidance sensor 61 comprises a sensor body 601 and a packaging base 603. The packaging base 603 is hermetically connected to the package side plate, so that a sealed space 605 for accommodating the sensor body 601 is formed between the packaging base 603 and the collision side plate 13. The light transmissive portion 132 can transmit signals emitted and received by the obstacle avoidance sensor 61, and at the same time can provide a dustproof effect to avoid contamination of the sensor body 601 by external dust. The light transmissive portion 132 is formed by a part of the light transmissive member, which can reduce the number of openings in the collision side plate 13, to give a more simplified appearance. One or two or more obstacle avoidance sensors 61 may be provided.
