[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 7 As shown, a new energy vehicle battery bracket comprises a battery bracket body 1 and a mounting shell 2 connected to the outside of the battery bracket body 1, an L-shaped fan plate 3 connected to the mounting shell 2 is connected to one side of the battery bracket body 1, a plurality of cooling fans 4 are connected to the inside of the L-shaped fan plate 3 away from the battery bracket body 1, a circular channel 8 is opened in the battery bracket body 1, a bottom channel 9 connected to the circular channel 8 is opened inside the bottom surface of the battery bracket body 1, a plurality of air inlets 6 and a plurality of air outlets 5 are opened on both sides of the battery bracket body 1, the air inlets 6 are connected to the air outlets on the L-shaped fan plate 3, and connecting ports connected to the air outlets 5 and the air inlets 6 are opened on both sides of the outer wall of the mounting shell 2.

[0023] like Figure 1 As shown, the new energy vehicle battery bracket in the utility model is similar to the existing new energy vehicle battery bracket structure, such as a new energy vehicle battery bracket disclosed in the patent with publication number CN218101528U. The main improvement of the utility model is to improve the heat dissipation effect of the battery bracket, such as Figures 1 to 7 As shown, when the new energy vehicle battery bracket in the utility model is in use, after the cooling fan 4 is started, the wind flow enters from the connecting port on the outside of the mounting shell 2 and is sucked into the air inlet 6 in the battery bracket 1 by the cooling fan 4. Because there are several air inlets 6, which just correspond to the separation areas in the battery bracket 1, the wind flow will enter the meandering channel 8 in the battery bracket 1 and dissipate the heat of the bottom surface of the battery pack in the bottom surface channel 9. Then, the wind flow after the heat exchange is completed is discharged from the several air outlets 5 until it flows out of the outside of the mounting shell 2. Through the continuous heat dissipation of the cooling fan 4, the matching arrangement of the meandering channel 8, the bottom surface channel 9, the air outlet 5 and the air inlet 6 is utilized, so that the wind flow can contact the side plate and the bottom surface of the battery bracket 1 with a larger area, thereby increasing the contact surface with the heat energy, thereby improving the heat dissipation effect of the battery bracket 1, and further achieving the improvement of the heat dissipation effect of the battery pack.

[0024] It is worth noting that the inductive opening of the cooling fan 4 is similar to the structure in the comparative document, and no further elaboration is given here.

[0025] By opening a circular channel 8 and a bottom channel 9 in the battery bracket 1 and connecting them with the air inlet 6 and the air outlet 5, under the blowing of the cooling fan 4, the wind can enter the several circular channels 8 and the bottom channel 9 from the air inlet 6 to exchange heat energy. The coordinated arrangement of the circular channel 8, the bottom channel 9, the air outlet 5 and the air inlet 6 allows the wind to contact the side panels and the bottom surface of the battery bracket 1 over a larger area, thereby increasing the contact area with the heat energy, thereby improving the heat dissipation effect of the battery bracket 1, and further improving the heat dissipation effect of the battery pack.

[0026] like Figure 3 and Figure 4 As shown, the bottom of the battery bracket body 1 is open and connected to a bottom plate 7 . A plurality of card slots 71 are provided around the bottom plate 7 . The card slots 71 are provided with elastic card plates 11 fixedly connected to the bottom of the battery bracket body 1 .

[0027] Specifically, during the heat dissipation process, dust will inevitably enter the circular channel 8 and the bottom channel 9 through the air inlet 6. At this time, the battery bracket 1 can be separated from the bottom plate 7. During separation, the elastic card plate 11 at the bottom of the battery bracket 1 can be separated from the card slot 71, thereby separating the two. By setting the bottom of the battery bracket 1 as a detachable structure, it is easy to clean the dust in the circular channel 8 and the bottom channel 9 in the battery bracket 1. By using the coordinated setting of the card slot 71 and the elastic card plate 11, the connection between the battery bracket 1 and the bottom plate 7 can be simple and convenient, making it more convenient, time-saving and labor-saving for workers to operate.

[0028] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the cross section of the air inlet 6 is a bell-mouth configuration. By configuring the air inlet 6 as a bell-mouth configuration, the wind speed can be increased, and the heat dissipation effect can be improved after the wind flow is accelerated.

[0029] like Figure 1 and Figure 2 As shown, filters are connected to the outsides of the air inlet 6 and the air outlet 5. The setting of the filters can reduce the dust from entering the meandering channel 8 and the bottom channel 9 in the battery bracket 1.

[0030] like Figure 4 As shown, a sealing strip is embedded in the contact surface between the battery bracket body 1 and the bottom plate 7. By embedding the sealing strip in the bottom surface of the battery bracket 1, after the battery bracket 1 and the bottom plate 7 are snapped together, a certain sealing effect can be achieved between the connection surfaces to prevent the air flow used for heat dissipation from being exposed, thereby reducing the heat dissipation effect.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
