[0028] [First Embodiment]

[0029] Such as Figures 1-4Shown is the first embodiment provided by the present utility model. This embodiment provides a heat dissipation grille, which includes a front side plate 1 close to the interior of the carriage and a rear side plate 2 far from the interior of the carriage and fixedly connected to the vehicle body. The front side plate 1 and the rear side plate 2 are arranged at intervals and in parallel. At the top between the front side plate 1 and the rear side plate 2, an upper side plate 3 is fixedly installed. At the bottom between the front side plate 1 and the rear side plate 2, a lower side plate 4 is fixedly installed. The upper side plate 3 is inclined with respect to the front side plate 1, and the lower side plate 4 is perpendicular to the front side plate 1. The rear side plate 2 extends downward beyond the lower side plate 4. The space enclosed by the front side plate 1, the rear side plate 2, the upper side plate 3, and the lower side plate 4 serves as a ventilation and air supply channel. Between the upper side plate 3 and the lower side plate 4, several reinforcing plates 5 connecting the front side plate 1 and the rear side plate 2 are also fixedly installed to further increase the internal support strength. Inside the lower side plate 4, several air inlets 41 are opened, and inside the front side plate 1, several air outlet grooves 11 are opened. The air inlets 41 and the air outlet grooves 11 communicate with each other. By setting the heat dissipation grille as a hollow structure surrounded by side plates, on the basis of ensuring sufficient strength through internal reinforcing plates, the self-weight is reduced. At the same time, through the combination of the internal hollow structure and the air inlets and air outlet grooves, an effective ventilation and air supply effect is achieved.

The upper fixing component 6 and the lower fixing component 7 are respectively fixedly connected to the vehicle body, and a sliding groove 21 is arranged inside the upper side plate 3. The upper fixing component 6 is fixedly connected inside the sliding groove 21. By setting the sliding groove 21, it is convenient to adjust the fixing position of the upper fixing component 6 on the heat dissipation grille as needed to meet the fixing requirements at different positions.

[0034] In this embodiment, the upper fixing component 6 includes an upper fixing frame 61. The upper fixing frame 61 is fixedly connected to the upper side plate 3 through an upper fixing member 62. An upper fixing hole 63 extending in the front-rear direction is further provided on the upper fixing frame 61. The lower fixing component 7 includes a lower fixing frame 71. The lower fixing frame 71 is fixedly connected to the rear side plate 2 through a lower fixing member 72.
