[0021] The realization, functional features and advantages of the purpose of the present utility model will be further described with reference to the embodiments and the drawings. Detailed Embodiments

[0022] In order to make the purpose, technical solutions and beneficial effects of the present utility model clearer and more understandable, the technical solutions in the present utility model will be further described below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] In the embodiment of the present utility model, as Figures 1 - 3As shown in the figure, the freight car compartment includes: a compartment body 1 and a rain shield 4; the compartment body 1 has a cargo cavity 3, and the compartment body 1 is provided with a rear door 2 for closing or opening the cargo cavity 3; the rain shield 4 has a front end and a rear end, the front end of the rain shield 4 is connected to the compartment body 1, and the rear end of the rain shield 4 extends backward to form a first shielding portion 401 and a second shielding portion 402. Along the height direction of the compartment body 1, the first shielding portion 401 is suspended above the rear door 2, and the projection of the second shielding portion 402 partially covers the first shielding portion 401.

[0024] Specifically, in the embodiment of the present invention, the compartment body 1 includes a front panel, two side panels, a rear door 2 and a top panel, which are used to enclose a cargo cavity 3; among them, the top panel includes a frame located on the outside, a plurality of reinforcing ribs provided in the frame, and a reinforcing plate connecting adjacent two reinforcing ribs (as Figure 1 shown, in order to show the above-mentioned cargo cavity 3, the reinforcing plate is omitted in this figure), and the frame on the outside is used to connect the front panel, the two side panels and the rear door 2.

[0025] In the embodiment of the present invention, the front end of the rain shield 4 is installed at one end of the frame close to the rear door 2, and the rear end of the rain shield 4 extends backward to form a first shielding portion 401 and a second shielding portion 402. The two shielding portions can provide double protection for the rear door 2, increasing the effect of preventing rainwater from intruding; at the same time, the double-layer design will make the whole structure more stable and durable, extending the service life of the rain shield 4. On the other hand, the first shielding portion 401 is suspended above the rear door 2, which will not only not occupy the space for the rear door 2 to open, but also play a good shielding role; the second shielding portion 402 partially projects and covers the first shielding portion 401, which can provide better protection in the case of strong wind and rain, reduce the random splashing of water droplets on the rear door 2, and facilitate the raindrops to slide along the preset path, reducing the possibility of rainwater seeping in from the gap and preventing backflow.

[0026] Such as Figure 2 、 Figure 3As shown, in one embodiment, the first shielding portion 401 and the second shielding portion 402 respectively have a first circular arc 403 and a second circular arc 404, and both the first circular arc 403 and the second circular arc 404 are bent towards the direction of the rear door 2. Specifically, in order to respectively define the paths of raindrops at the two shielding portions, in this embodiment, the first circular arc 403 and the second circular arc 404 are respectively arranged at the two shielding portions, so that the circular arc design helps to guide rainwater to flow along a smooth surface, thereby avoiding water droplet retention or the formation of a water curtain, and further improving the waterproof performance; moreover, in cold regions, the circular arc design can also reduce the accumulation of snow, ice and frost, and reduce the winter maintenance cost. At the same time, the circular arc edge can disperse stress more than a sharp corner, which helps to improve the overall structural strength of the shielding portion and make it more durable. In addition, the circular arc surface is not easy to accumulate dust and dirt, and is relatively easy to clean. In addition, the circular arc edge can reduce air resistance compared with a straight edge, and improve the aerodynamic efficiency when the vehicle is driving.

[0027] Preferably, the centers of the first circular arc 403 and the second circular arc 404 are arranged at intervals; to form a double waterproof barrier, that is: it can prevent water flow from staying on a single curved surface, promote the rapid discharge of water flow, and reduce the possibility of water accumulation; it can also better block wind and rain from different angles and improve the overall protection effect of the shielding portion. In addition, the two circular arcs can support each other to increase the structural stability and anti-deformation ability, especially when the vehicle encounters bumps or wind forces during driving. When under strong wind conditions, the circular arcs arranged at intervals can better disperse the wind force, reduce the situation of excessive local stress, and improve the wind pressure resistance performance of the entire rain shield 4.

[0028] Preferably, along the height direction of the vehicle body 1, both the first circular arc 403 and the second circular arc 404 are located below the extension line of the top of the vehicle body 1. The top of the vehicle body 1 is the frame of the roof panel, and the extension line of this frame extends backward, so that both circular arcs are located below this extension line; in this way, the wind resistance can be effectively reduced, so that the rain shield 4 can avoid the windward side.

[0029] As Figure 2 、 Figure 3 As shown, in one embodiment, both the first shielding portion 401 and the second shielding portion 402 converge to the rear end of the rain shield 4, and a gap is formed therebetween. Specifically, in order to improve the drainage function of the rain shield 4, in this embodiment, a gap is arranged between the two shielding portions. The existence of the gap can help drain water, prevent rainwater from accumulating between the shielding portions, thereby reducing the time of water retention and improving the drainage efficiency. And the gap can also reduce the contact area between the shielding portions, which helps to reduce the resonance phenomenon caused by wind force and extend the service life of the components.

[0030] As Figure 3As shown, in one embodiment, the front end of the rain shield 4 is provided with a mounting portion 405, and the mounting portion 405 extends along the height direction of the box body 1. Specifically, in order to mount the front end of the rain shield 4 at the box body 1, in this embodiment, a mounting portion 405 is provided at the front end of the rain shield 4, and the mounting portion 405 extends along the height direction of the box body 1 to increase the contact area with the box body 1, thereby improving the overall stability of the rain shield 4. Further, the mounting portion 405 is provided with a plurality of mounting through holes 406, and the plurality of mounting through holes 406 are arranged at intervals along the width direction of the box body 1, so as to fix the mounting portion 405 to the frame of the top plate by using connecting members such as screws, so that the rain shield 4 and the rear door 2 are independent of each other and do not interfere with each other.

[0031] As Figure 2 , Figure 3 shown, in one embodiment, along the width direction of the box body 1, both opposite sides of the rain shield 4 are provided with stoppers 5, and the stoppers 5 are sealingly connected to the mounting portion 405. Specifically, since the rain shield 4 is arranged along the width direction of the box body 1 and its opposite sides are in a hollow shape, in order to prevent rainwater from leaking into the gap of the rear door 2 from this place, in this embodiment, stoppers 5 are provided on both side surfaces, and the stoppers 5 are sealingly connected to the mounting portion 405 and the rain shield 4 to seal the side surfaces of the rain shield 4 and further improve the rain shielding effect of the rain shield 4.

[0032] As Figure 2 , Figure 3 shown, in one embodiment, the rain shield 4 is provided with a plurality of flow guiding blocks 6 at intervals, and the flow guiding blocks 6 extend along the length direction of the box body 1. Specifically, the plurality of flow guiding blocks 6 can better guide the water flow to ensure that the rainwater can be discharged along a predetermined path instead of splashing randomly, reducing the possibility of water droplets splashing. At the same time, the flow guiding blocks 6 can not only play a role in guiding the flow, but also serve as reinforcing ribs to enhance the overall structural strength of the rain shield 4 and reduce deformation under high-speed driving or strong wind conditions. In addition, the reasonably arranged flow guiding blocks 6 can improve the aerodynamic characteristics, reduce the wind resistance, and contribute to improving the fuel economy of the vehicle.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
