[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0024] In the following description, many specific details are set forth to facilitate a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0025] Please refer to Figure 1 - Figure 5, the present utility model provides a technical solution: a protection structure for the intake pipe of a high-voltage battery, including an intake pipe main body 1. A protection component 2 is arranged at the intake port of the intake pipe main body 1. The protection component 2 includes a protection box 201. A protection net 202 is arranged inside the protection box 201. Insertion holes 203 are formed on the outer surfaces of both sides of the protection net 202. First notch openings 204 are formed inside the protection box 201 on both sides close to the protection net 202. A first spring 205 is arranged inside the first notch openings 204. A groove 206 is formed directly below the first notch openings 204. One side of the first spring 205 is connected to a push block 207. The bottom of the push block 207 is connected to a fixing block 208. One side of the push block 207 is connected to an insertion block 209. Second notch openings 210 are formed on the inner bottom surfaces of both sides of the protection box 201. A second spring 211 is arranged inside the second notch openings 210. The top of the second spring 211 is connected to a top block 212. A sliding connection is formed between the protection net 202 and the protection box 201. The inner walls of both sides of the protection box 201 are in contact with the inner walls of both sides of the protection net 202. An elastic structure is formed between the push block 207 and the first spring 205 through the first notch openings 204. An inclined opening is formed on one side of the insertion block 209. The position and size of the insertion block 209 match the position and size of the insertion holes 203. A snap connection is formed between the insertion block 209 and the insertion holes 203.

[0026] The effect achieved by the entire embodiment 1 is that when the cooling air enters the intake pipe main body 1, it will first pass through the protection net 202 to filter and isolate dust and other impurities, ensuring that the dust and impurities will not enter the interior of the intake pipe main body 1. When, after a long time of use, it is necessary to disassemble and clean the protection net 202, the two fixing blocks 208 can be pulled simultaneously to both sides with fingers, and then the push block 207 is driven by the fixing block 208 to squeeze the first spring 205, so that the insertion block 209 can be withdrawn from the insertion holes 203. At this time, the second spring 211 will push the top block 212 through its own elastic force, and push the protection net 202 out of the protection box 201 to complete the disassembly of the protection net 202. After that, the protection net 202 can be cleaned. When, after the cleaning of the protection net 202 is completed and it is necessary to install the protection net 202 into the protection box 201, the protection net 202 can be directly pushed into the protection box 201. When the protection net 202 contacts the inclined opening position of the insertion block 209 and continues to move downward, the insertion block 209 is squeezed, and the push block 207 is pushed to compress the first spring 205. When the protection net 202 is completely installed into the intake pipe main body 1, the first spring 205 will push the push block 207 through its own elastic force, so that the push block 207 can drive the insertion block 209 to insert into the insertion holes 203 to fix the protection net 202. In this way, the installation of the protection net 202 is completed, which can prevent sundries and dust from entering through the intake pipe main body 1 and adhering to the battery module or the cooling system, resulting in the failure of the cooling system.

[0027] Embodiment 2, as Figure 1 , Figure 2 and Figure 6 shown, a flow regulating component 3 is provided at the bottom of the intake pipe main body 1. The flow regulating component 3 includes a control box 301. An adjusting plate 302 is arranged inside the control box 301. A threaded hole 303 is opened inside the adjusting plate 302. A one-way screw rod 304 is arranged inside the threaded hole 303. One end of the one-way screw rod 304 is connected to a servo motor 305. A bearing sleeve 306 is embedded in one side inside the control box 301. A rotational connection is formed between the one-way screw rod 304 and the bearing sleeve 306. A threaded connection is formed between the one-way screw rod 304 and the adjusting plate 302 through the threaded hole 303. The servo motor 305 is electrically connected to an external power supply through a control switch.

[0028] The overall effect achieved by the entire Embodiment 2 is that when it is necessary to adjust the gas flow rate inside the intake pipe main body 1, the forward and reverse rotation functions of the servo motor 305 can be remotely controlled, so that the servo motor 305 can drive the one-way screw rod 304 to rotate forward and backward. When the one-way screw rod 304 rotates forward, it will perform threaded rotation with the adjusting plate 302 through the threaded hole 303, and through the threaded rotation, the adjusting plate 302 will move inward to reduce the intake air flow rate. When it is necessary to increase the intake air flow rate, the reverse rotation function of the servo motor 305 can be turned on to drive the one-way screw rod 304 to rotate in the reverse direction, so that the adjusting plate 302 can move outward through threaded rotation, thereby increasing the intake air volume. In this way, the adjustment of the air flow rate can be realized according to the actual usage situation, improving the practicability of the intake pipe main body 1.

[0029] Working principle: When the cooling air enters the intake pipe main body 1, it will first pass through the protective net 202 to filter and isolate dust and other impurities, so as to prevent sundries and dust from entering through the intake pipe main body 1 and adhering to the battery module or the cooling system, causing the cooling system to fail. When it is necessary to adjust the gas flow rate inside the intake pipe main body 1, the forward and reverse rotation functions of the servo motor 305 can be remotely controlled, so that the one-way screw rod 304 can adjust the position of the adjusting plate 302 through threaded rotation, thereby realizing the adjustment of the air flow rate according to the actual usage situation and improving the practicability of the intake pipe main body 1.

[0030] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
