[0086] The embodiment of the utility model provides a kind of anti-ponding tank bottom structure 100.The anti-ponding tank bottom structure 100 can include bottom side beam 101, intermediate longitudinal beam 102, first floor member 103 and first water receiving box 106.Bottom side beam 101 is provided with a pair of pair of bottom side beam 101 can be two bottom side beams 101.Bottom side beam 101 extends along length direction D1.A pair of bottom side beam 101 is oppositely and interval arranged in width direction D2.Intermediate longitudinal beam 102 extends along length direction D1.Intermediate longitudinal beam 102 is located between a pair of bottom side beam 101 in width direction D2.First floor member 103 can be part of the floor of tank structure.The upper side of first floor member 103 is suitable for arranging battery cluster.First floor member 103 is located between bottom side beam 101 and intermediate longitudinal beam 102 in width direction D2.First floor member 103 includes at least one bottom groove wall, at least two side groove walls 104b and at least two support walls 104c.Each of the two sides of any bottom groove wall in length direction D1 is provided with side groove wall 104b and support wall 104c.Bottom groove wall is lower than support wall 104c.Side groove wall 104b is located between bottom groove wall and support wall 104c and is fixed to bottom groove wall.Support wall 104c is connected to the upper end of side groove wall 104b and is arranged in length direction D1 and extends away from bottom groove wall.Bottom groove wall and side groove wall 104b located on the two sides of bottom groove wall in length direction D1 enclose water receiving groove 103a opening upward.Bottom groove wall has first end close to intermediate longitudinal beam 102 and second end away from intermediate longitudinal beam 102.First end is higher than second end.Support wall 104c is suitable for being connected to the column of battery cluster.Support wall 104c can be one of the structures capable of bearing load in some examples.First water receiving box 106 is located below first floor member 103.First water receiving box 106 is communicated with water receiving groove 103a corresponding to the second end of bottom groove wall.The bottom of first water receiving box 106 includes liquid discharge member 106a suitable for discharging liquid.Here, liquid discharge member 106a can be one or a combination of openable valve, liquid discharge pipe and the like.

[0087] ​According to the water accumulation prevention tank bottom structure 100, the water receiving groove 103a is arranged on the upper portion of the first floor member 103 to collect liquid such as condensed water, thereby preventing the upper surface of the support wall 104c from accumulating water. Moreover, the bottom groove wall is arranged in a structure form that the first end is higher than the second end, so that the collected liquid can be guided towards the direction close to the bottom side beam 101, thereby preventing the liquid from accumulating in the area close to the intermediate longitudinal beam 102. Further, the water receiving box is arranged below the first floor member 103, and the water receiving box is communicated with the water receiving groove 103a corresponding to the second end of the bottom groove wall, so that the liquid in the water receiving groove 103a can be discharged into the water receiving box, which helps to reduce or empty the liquid in the water receiving groove 103a. Furthermore, the lower portion of the water receiving box is provided with a drainage member to discharge the liquid in the water receiving box, so as to ensure that the function of the liquid discharge channel formed by the water receiving groove 103a and the water receiving box can be continuously and stably realized. In the application state of the water accumulation prevention tank bottom structure 100 applied to the container, the risk of damage and failure of the electrical components such as the battery or the circuit board due to short circuit caused by condensed water and the like can be reduced or avoided, and the corrosion of the container interior caused by water accumulation can also be prevented or avoided.

[0088] Exemplarily, the height of the side groove wall 104b increases in the direction parallel to the length direction D1 and away from the bottom groove wall. In this way, the condensed water located on the support wall 104c or falling from the battery cluster can be guided to the bottom groove wall.

[0089] Optionally, the side groove wall 104b is inclined to the length direction D1 and the height direction D3.

[0090] Exemplarily, the bottom groove wall can include a first bottom wall portion 105a and a second bottom wall portion 104a. The first bottom wall portion 105a is closer to the intermediate longitudinal beam 102 than the second bottom wall portion 104a in the width direction D2. The height of the first bottom wall portion 105a increases in the direction parallel to the width direction D2 and close to the intermediate longitudinal beam 102. The first bottom wall portion 105a can guide the liquid to the second bottom wall portion 104a. The second bottom wall portion 104a serves as a transfer area or a buffer area for discharging the liquid downward. The second bottom wall portion 104a is located at the lowermost position of the bottom groove wall. Correspondingly, the water receiving box is communicated to the water receiving groove 103a at the position corresponding to the second bottom wall portion 104a, so as to facilitate faster discharge of the liquid in the water receiving groove 103a.

[0091] Optionally, the second bottom wall portion 104a is parallel to the support wall 104c. For example, the second bottom wall portion 104a and the support wall 104c can be horizontal plate bodies perpendicular to the height direction D3.

[0092] Optionally, the first bottom wall portion 105a has a dimension in the width direction D2 that is greater than the dimension of the second bottom wall portion 104a in the width direction D2. In the case that liquid accumulates in the water collecting groove 103a, the liquid will first accumulate in the second bottom wall portion 104a. Accumulating liquid in the second bottom wall portion 104a, which is a smaller area, instead of simultaneously accumulating liquid in each portion of the bottom groove wall, is conducive to reducing the water accumulation area.

[0093] Referring to Figure 1 , Figure 3 , Figure 4 , and Figures 7 to 9 , exemplarily, the first floor member 103 can include a first plate 104 and a second plate 105.

The second plate 105 can be welded to the intermediate longitudinal beam 102 and the first plate 104 by welding or the like. The welding form here can be spot welding. On the basis of using spot welding, the gap between the second plate 105 and the first plate 104 can be connected and sealed by using a glue application method.

The first bottom cross beam 109 is connected to the bottom side beam 101 and the intermediate longitudinal beam 102 along the width direction D2. The upper portion of the first bottom cross beam 109 is connected to the first floor member 103 at a position corresponding to the support wall 104c. The second bottom cross beam 111 is connected to the bottom side beam 101 and the intermediate longitudinal beam 102 along the width direction D2.

The first bottom cross beam 109 is made of, for example, a square steel tube or a C-shaped steel. The second bottom cross beam 111 is made of, for example, a C-shaped steel.

[0097] Further optionally, the part of the support wall 104c corresponding to the first bottom cross beam 109 can be holed by means such as laser cutting, so that the column of the battery cluster is directly welded with the first bottom cross beam 109, ensuring the levelness of the support of the battery cluster and the strength of the connecting structure of the battery cluster and the box bottom structure 100. It can be understood that the column is welded with the support wall 104c.

[0098] It can be understood that the water accumulation prevention box bottom structure 100 of the embodiments of the present application can include other bottom cross beams in addition to the first bottom cross beam 109 and the second bottom cross beam 111, so as to further improve the bearing performance of the area where the first floor member 103 is located or ensure the bearing performance of other areas.

The water guide 108 is connected between the first floor member 103 and the bottom side beam 101 in the width direction D2. The upper portion of the water guide 108 is formed with a water guide groove 108a. The water guide groove 108a is connected to each water receiving groove 103a. At least part of the first floor member 103 is provided with a drain hole. The drain hole is used to mount the first floor drain 107. By providing the first floor drain 107, the filtering function of filtering foreign matter such as particulate matter, fibrous or filamentous matter, etc. can be achieved while achieving drainage, so as to prevent the drain hole from being blocked. In the example in which only part of the first floor member 103 is provided with the drain hole and the first floor drain 107, by providing the water guide 108, the accumulated water in the water receiving groove 103a not provided with the first floor drain 107 can be guided to the water receiving groove 103a provided with the first floor drain 107, so as to achieve the purpose of draining the accumulated water in the water receiving groove 103a. In the example in which all of the first floor members 103 are provided with the drain hole and the first floor drain 107, by providing the water guide 108, each water receiving groove 103a can be connected, so that in the case that the drainage of part of the water receiving groove 103a is abnormal or part of the water receiving box is full, the liquid can be guided to the water receiving groove 103a still having the drainage function, so as to prevent water accumulation.

[0100] Optionally, the first floor drain 107 can be implemented by using the floor drain structure in the prior art.

The first vertical wall and the second vertical wall are oppositely arranged in the width direction D2. The intermediate wall is connected between the lower end of the first vertical wall and the lower end of the second vertical wall. The first vertical wall is lower than the second vertical wall. For example, the upper end of the second vertical wall is close to but does not exceed the upper surface of the bottom side beam 101. The upper end of the first vertical wall is close to but does not go below the upper surface of the second bottom wall portion 104a. Alternatively, the upper end of the second vertical wall is higher than the upper surface of the second bottom wall portion 104a, but an opening is provided at a position corresponding to each water receiving groove 103a to ensure better communication between the water receiving groove 103a and the water guide groove 108a.

[0102] Optionally, on either side of the intermediate longitudinal beam 102, one integral water guide 108 can be provided, or a plurality of water guides 108 can be arranged in series in the length direction D1 and spliced to each other.
