[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0022] Figure 1 The frame 1 is shown with the battery compartment front guard assembly of the utility model installed, the frame 1 includes a battery compartment 12, and a front guard 3 tiltedly arranged at the front side of the battery, as shown in FIG. Figure 2-3 A plurality of ventilation holes 34 are provided on the front guard plate 3 , and guide strips 32 , 33 are provided on one side of the ventilation holes 34 .

[0023] The ventilation holes 34 are used to ventilate the battery compartment 12, thereby dissipating heat for the batteries in the battery compartment. The guide strips are used to guide part of the rainwater to the lower side of the front guard plate 3, thereby reducing or avoiding the impact of rainwater on the battery compartment.

[0024] As pointed out, waterproof facilities can also be provided in the battery compartment 12. The front guard plate assembly of the utility model reduces the entry of rainwater while ventilating.

[0025] The guide strips include a front guide strip 32 and / or a rear guide strip 33 . The front guide strip 32 is arranged at the front side of the front guard plate 3 , and the rear guide strip 33 is arranged at the rear side of the front guard plate 3 .
