Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and in particular to a cargo box and vehicle. Background Technology
[0002] Currently, new energy trucks have become the development trend of trucks, and electric trucks are widely used. During vehicle operation, the cargo box, being the largest dimension of the vehicle in terms of width and height, has the greatest impact on wind resistance at the front. If the wind resistance of the cargo box can be reduced, then the vehicle's energy consumption can be further reduced and the range can be increased, which is especially important for new energy vehicles.
[0003] Most of the cargo boxes in related technologies are vertical corrugated cargo boxes. Although the outer surface of the vertical corrugated cargo box has been smoothly transitioned, the wind resistance is still relatively large because the vertical corrugations extend in the vertical direction and the windward area is large during vehicle movement.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will understand that modifications and variations can be made to the present invention without departing from the scope or spirit of the invention. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.
[0026] The following reference Figures 1 to 3 This utility model provides a cargo box, including a box body 1 and a first crossbeam 2. The box body 1 has a first side surface (e.g., ...) in its width direction. Figure 1 The right side shown) and the second side (as shown) Figure 1 As shown on the left side), there are multiple first crossbeams 2, which are distributed on the first side and the second side. The multiple first crossbeams 2 extend along the length of the box body 1 and are spaced apart along the height of the box body 1. The outer contour of the cross section of the first crossbeam 2 is an isosceles trapezoid.
[0027] like Figures 1 to 3 As shown, the first crossbeam 2 extends along the front-to-back direction, and multiple first crossbeams 2 are distributed on the left and right sides respectively. It should be noted that the number of first crossbeams 2 on the left and right sides of the box body 1 is the same, and the first crossbeams 2 on the left and right sides are arranged opposite each other in the left-to-right direction, and the first crossbeams 2 on the left and right sides are arranged in parallel.
[0028] Multiple first crossbeams 2 are evenly spaced in the vertical direction. The outer contour of the cross section of the first crossbeam 2 is an isosceles trapezoid, and the side of the outer contour of the cross section of the first crossbeam 2 closest to the outside of the box 1 is the shorter side.
[0029] For example, the number of first crossbeams 2 on one side can be 16 to 18.
[0030] In this embodiment of the utility model, the first crossbeam 2 extends along the front-to-back direction in the cargo box. During vehicle operation, the laterally extending first crossbeam 2 can act as an air guide, thereby reducing the wind resistance of the cargo box and thus reducing the vehicle's energy consumption.
[0031] In some embodiments, the first crossbeam 2 has a first side and a second side in its height direction, the length of the first side is A, the length of the second side is B, and 30mm≤A≤60mm, 70mm≤B≤100mm.
[0032] Specifically, such as Figure 3As shown, the first side is the side of the first crossbeam 2 away from the box body 1, and the second side is the side closer to the box body 1. For example, the length of the first side can be 30mm, 40mm, 45mm, 50mm, or 60mm, and the length of the second side can be 70mm, 80mm, 85mm, 90mm, or 100mm.
[0033] It should be noted that when the height of the first crossbeam 2 remains constant, the drag coefficient of the first crossbeam 2 is positively correlated with the cross-sectional area of the first crossbeam 2. In other words, the larger the cross-sectional area, the greater the drag coefficient.
[0034] In some embodiments, the height of the first crossbeam 2 is H, and 15mm≤H≤25mm.
[0035] Specifically, such as Figure 3 As shown, the height of the first crossbeam 2 can be 15mm, 20mm, 23mm, or 25mm.
[0036] It should be noted that the drag coefficient of the cargo box is related to the protruding area of the first crossbeam 2. Within a certain range, the larger the protruding area of the first crossbeam 2, the smaller the drag coefficient. Considering the weight of the first crossbeam 2, the height of the first crossbeam 2 is determined to be between 15mm and 25mm.
[0037] Optionally, the thickness of the first crossbeam 2 is 0.6 mm to 0.8 mm. For example, the thickness of the first crossbeam 2 can be 0.6 mm, 0.7 mm or 0.8 mm.
[0038] In some embodiments, the interval between two adjacent first crossbeams 2 in the plurality of first crossbeams 2 is C, and 100mm≤C≤130mm.
[0039] Specifically, such as Figure 3 As shown, the spacing between two adjacent first crossbeams 2 can be 100mm, 110mm, 120mm, or 1300mm. It should be noted that when the spacing between two adjacent first crossbeams 2 is too large, the number of first crossbeams 2 per unit surface area decreases, leading to a reduction in the support effect on the housing 1. Conversely, when the spacing between the first crossbeams 2 is too small, the number of first crossbeams 2 becomes excessive, increasing the overall weight of the housing 1 and consequently increasing energy consumption.
[0040] In some embodiments, the cargo box further includes a plurality of second crossbeams 3, and the box body 1 has a third side and a fourth side in its height direction, with the plurality of second crossbeams 3 distributed on the third side (e.g., Figure 1 The upper end face of the box 1 shown) and the fourth side face (as shown) Figure 1On the lower end face of the box 1 shown, the second crossbeam 3 extends along the length direction of the box 1, and multiple second crossbeams 3 are arranged at intervals in the width direction of the box 1.
[0041] Specifically, such as Figure 1 As shown, the second crossbeam 3 is located on the upper and lower ends of the box body 1. The second crossbeam 3 extends in the front-to-back direction. The second crossbeam 3 can be a continuous beam or a segmented arrangement, for example, as shown in the figure. Figure 1 As shown, the second crossbeam 3 is divided into two sections and is broken at the middle of the box body 1. By arranging the second crossbeam 3 in sections, the overall weight of the box body 1 can be reduced while ensuring the structural strength of the box body 1.
[0042] In some embodiments, the cargo box further includes a plurality of first vertical beams 4, which are located on a first side and a second side respectively, and the first vertical beams 4 extend along the height direction of the box body 1 and are located at the middle of the box body 1 in the length direction of the box body 1.
[0043] Specifically, such as Figure 1 As shown, there can be two first vertical beams 4. The two first vertical beams 4 are located on the left and right sides of the box body 1, respectively. The first vertical beams 4 on the left and right sides are arranged opposite each other and parallel to each other.
[0044] The first vertical beam 4 is located in the middle of the box body 1 in the front-to-back direction. Adding the first vertical beam 4 can improve the overall strength of the box body 1.
[0045] Optionally, the outer surface of the first vertical beam 4 is an arc-shaped surface to ensure a smooth transition of airflow, thereby further reducing the drag coefficient.
[0046] In some embodiments, the dimension of the first vertical beam 4 in the length direction of the box body 1 is D, and 90mm≤D≤110mm.
[0047] For example, the width of the first vertical beam 4 in the front-to-back direction can be 90mm, 100mm, 105mm, or 110mm. If the width of the first vertical beam 4 is too large, it will lead to an increase in the drag coefficient. Conversely, if the width of the first vertical beam 4 in the front-to-back direction is too small, it will cause the structural strength of the box 1 to fail to meet the requirements.
[0048] In some embodiments, the inner side of the housing 1 and / or the inner side of the first vertical beam 4 are provided with reinforcing ribs (not shown).
[0049] For example, the reinforcing ribs can be two vertical reinforcing ribs extending in the vertical direction and one horizontal reinforcing rib extending in the front-back direction.
[0050] The reinforcing ribs can be placed on the inner side of the box body 1, or inside the first vertical beam 4, or inside the first horizontal beam 2, or inside the second horizontal beam 3, or all three sides of the box body 1, the first vertical beam 4, the first horizontal beam 2, and the second horizontal beam 3 can be reinforced with reinforcing ribs. By adding reinforcing ribs, the overall structural strength of the box body 1 can be improved.
[0051] Optionally, the first crossbeam 2, the second crossbeam 3, and the first vertical beam 4 can be integrally formed with the box body 1, or the first crossbeam 2, the second crossbeam 3, and the first vertical beam 4 can be connected to the box body 1 by welding, and the contact surfaces of the first crossbeam 2, the second crossbeam 3, and the first vertical beam 4 with the box body 1 are sealed to prevent air from entering the beam body and increasing wind resistance.
