[0032] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.
[0033] As Figures 1 to 6 shown, this embodiment provides a car body structure, which includes a car body 1 and a cover 2. A first installation cavity 111 and a first opening 112 communicating with the first installation cavity 111 are provided inside the car body 1. The first opening 112 is located on the top wall of the car body 1. One or two side walls of the car body 1 along the vehicle width direction of the car body 1 are provided with air vents 113, and the air vents 113 communicate with the first installation cavity 111; a second installation cavity 21 and a second opening 22 communicating with the second installation cavity 21 are provided inside the cover 2. The cover 2 is fixedly arranged on the top wall of the car body 1. The cover 2 covers the first opening 112 and makes the first opening 112 and the second opening 22 communicate. An air inlet 231 is provided on the side wall of the cover 2 opposite to the rear of the car body 1. When the vehicle provided with this car body structure moves forward, the front of the car body 1 is in the windward side. Since there are no air inlets 231 or air vents 113 on the windward sides of the car body 1 and the cover 2, the entry of external rainwater can be avoided. The air inlet 231 is provided on the side wall of the cover 2 opposite to the rear of the car body 1. Only when the vehicle is reversing, the side wall where the air inlet 231 is located will become the windward side, and most of the usage scenarios of the vehicle are in the forward state of the vehicle. Therefore, setting the air inlet 231 on the side wall of the cover 2 opposite to the rear of the car body 1 can effectively reduce the entry of external rainwater into the second installation cavity 21 and the first installation cavity 111 through the air inlet 231. The air vents 113 are provided on one or two side walls of the car body 1 along the vehicle width direction of the car body 1. Compared with the front of the car body 1, the two side walls of the car body 1 along the vehicle width direction rarely become the windward side. Therefore, this setting can effectively reduce the entry of external rainwater into the first installation cavity 111 through the air vents 113. In summary, when the electrical equipment is arranged in the first installation cavity 111 and / or the second installation cavity 21, the setting positions of the air inlet 231 and the air vents 113 can well improve the entry amount of external rainwater. This setting can effectively improve the entry of external rainwater while realizing ventilation and heat dissipation of the electrical equipment.
[0034] Specifically, two air vents 113 are provided, and the two air vents 113 are respectively arranged on the two side walls of the car body 1 along the vehicle width direction.
[0035] As Figure 3As shown, for how the first installation cavity 111 is formed, optionally, the vehicle body shell 1 includes an outer shell 11, a bottom plate 12, and a rear baffle 13. An accommodation cavity is provided inside the outer shell 11. The bottom plate 12 and the rear baffle 13 are both arranged in the accommodation cavity. The bottom plate 12, the rear baffle 13, the top wall of the outer shell 11, the front wall of the outer shell 11 at the vehicle head position, and the two side walls of the outer shell 11 in the width direction enclose the first installation cavity 111. The first opening 112 is provided on the top wall of the outer shell 11. The bottom plate 12 is provided with a maintenance door, and the electrical equipment in the first installation cavity 111 can be installed and maintained through the maintenance door.
[0036] Optionally, the cover 2 is an integrally formed part.
[0037] As Figure 4 shown, optionally, the side wall of the cover 2 provided with the air inlet 231 is concavely provided with a rainproof groove 23. The bottom wall of the rainproof groove 23 is perpendicular to the top wall of the vehicle body shell 1. The air inlet 231 is provided on the bottom wall of the rainproof groove 23. The lower side wall of the rainproof groove 23 forms a preset angle a with the bottom wall of the rainproof groove 23, and a > 90°. In this embodiment, the bottom wall of the rainproof groove 23 is perpendicular to the top wall of the vehicle body shell 1, and the air inlet 231 is provided on the bottom wall of the rainproof groove 23. This setting can enable the peripheral wall of the rainproof groove 23 to block the air inlet 231 on the bottom wall of the rainproof groove 23, and can more effectively improve the rain shielding effect on the outside rain. The lower side wall of the rainproof groove 23 forms a preset angle a with the bottom wall of the rainproof groove 23, and a > 90°. This setting can enable the rainwater in the rainproof groove 23 to flow out of the rainproof groove 23 along the lower side wall of the rainproof groove 23.
[0038] Optionally, the vehicle body shell structure further includes a grille plate 3. The grille plate 3 closes the rainproof groove 23 and is spaced from the bottom wall of the rainproof groove 23. In this embodiment, the grille holes on the grille plate 3 point to the top wall of the vehicle body shell 1. This setting can effectively block the outside rainwater from entering the second installation cavity 21. The grille plate 3 is spaced from the bottom wall of the rainproof groove 23. This setting can enable the rainwater passing through the grille plate 3 to enter the space between the grille plate 3 and the bottom wall of the rainproof groove 23, and further can effectively reduce the amount of rainwater passing through the grille plate 3 and directly entering the first installation cavity 111 through the air inlet 231.
[0039] Optionally, the grille plate 3 is provided with multiple rows of grille holes in the vertical direction, and the row of grille holes close to the vehicle body shell 1 in the vertical direction is flush with the lower side wall of the rainproof groove 23. In this embodiment, the above setting can enable the rainwater on the lower side wall of the rainproof groove 23 to flow out of the rainproof groove 23 through the row of grille holes close to the vehicle body shell 1, and avoid the accumulation of rainwater in the space enclosed by the rainproof groove 23 and the grille plate 3.
[0040] Optionally, the peripheral wall of the grille plate 3 is adhesively bonded to the peripheral wall of the rainproof groove 23. In this embodiment, the peripheral wall of the grille plate 3 and the peripheral wall of the rainproof groove 23 can be hermetically fixed by glue, thereby preventing external rainwater from entering the space enclosed by the grille plate 3 and the rainproof groove 23 through the gap between the peripheral wall of the grille plate 3 and the peripheral wall of the rainproof groove 23.
[0041] As Figure 3 shown, optionally, the vehicle body structure further includes a mounting skeleton 4, the mounting skeleton 4 is fixed on the top wall of the vehicle body 1, and the mounting skeleton 4 passes through the second opening 22 and is fixedly connected to the cover 2. In this embodiment, the mounting skeleton 4 can realize the relative fixation between the vehicle body 1 and the cover 2. Optionally, the cover 2 and the mounting skeleton 4 are fixedly connected by bolts. In other embodiments, the cover 2 and the mounting skeleton 4 are connected by a clamping structure.
[0042] As Figure 6 shown, optionally, the air outlet 113 is a grille opening. In this embodiment, the grille opening faces the ground, and this setting can further reduce the amount of rainwater entering through the air outlet 113.
[0043] As Figure 3 shown, optionally, the vehicle body structure further includes a fan 5, and the fan 5 is opposite to the air outlet 113. In this embodiment, there are two fans 5, and the two fans 5 are respectively opposite to the two air outlets 113. Setting the fan 5 can accelerate the flow of gas in the first installation cavity 111 and the second installation cavity 21, thereby improving the heat dissipation efficiency of the electrical equipment in the first installation cavity 111 and / or the second installation cavity 21.
[0044] As Figure 6 shown, optionally, both ends of the cover 2 extend out of the vehicle body 1 in the vehicle width direction, and auxiliary air inlets 24 are respectively arranged on the bottom walls of both ends of the cover 2 opposite to the vehicle body 1, and the auxiliary air inlets 24 communicate with the second installation cavity 21. In this embodiment, the auxiliary air holes face the ground, thereby effectively reducing the entry of external rainwater into the second installation cavity 21 through the auxiliary air inlets 24. At the same time, the auxiliary air inlets 24 can further increase the air intake volume entering the second installation cavity 21, thereby improving the heat dissipation efficiency of the electrical equipment in the first installation cavity 111 and / or the second installation cavity 21.
[0045] This embodiment also provides a vehicle, including the vehicle body structure in the above solution.
