[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As the first embodiment of this utility model: an engine intake pipe assembly, including: a sliding base 310 and a sliding connecting box 400, the sliding base 310 and the rigid pipe section 300 are an integral structure, and a slider 320 is provided on the top of the sliding base 310, the slider 320 is located inside the sliding connecting box 400.

[0025] Several sets of balls 321 are embedded in the lower surface of the slider 320 at the front and rear positions. A sliding groove 410 is provided inside the sliding connection box 400. A reset spring 420 for resetting the slider 320 is installed on the left and right sides of the inner side of the sliding groove 410. A rolling groove 440 is provided on the lower surface of the inner side of the sliding groove 410 at the front and rear positions.

[0026] A flexible hose section 100 connected to the intercooler is installed on the right side of the rigid pipe section 300, and a flexible hose section 200 connected to the engine is installed on the left side of the rigid pipe section 300. The rigid pipe section 300, flexible hose section 100, and flexible hose section 200 together form an intake pipe.

[0027] The sliding connection box 400 has a mounting plate 430 on its top. The mounting plate 430 is fixed to the bottom of the frame on the left and right sides by two sets of bolts. The sliding connection box 400 is set horizontally.

[0028] The lower surface of the sliding connection box 400 is provided with a moving groove, which is connected to the sliding groove 410. The specifications of the moving groove are matched with the specifications of the connection part between the slider 320 and the sliding base 310.

[0029] The sliding groove 410 is fixed to a pair of return springs 420 on the left and right sides of its inner side, and a push plate 421 is fixed to the opposite side of the pair of return springs 420. The specifications of the return springs 420 and the push plate 421 are matched with the specifications of the sliding groove 410.

[0030] In actual use, the mounting plate 430 on the top of the sliding connection box 400 is fixed to the bottom of the frame with two sets of bolts, thus installing the sliding connection box 400 under the frame and keeping it parallel to the horizontal plane. When the engine is running, it vibrates, and the slider 320 moves left and right along the inner side of the sliding groove 410. At the same time, the connection part between the slider 320 and the sliding base 310 moves left and right along the moving groove, which in turn drives the rigid pipe section 300 to move left and right under the sliding connection box 400. When the slider 320 moves left and right inside the sliding groove 410, it pushes the left push plate 421 to the left and squeezes the left return spring 420. At the same time, the right push plate 421 moves to the left and stretches the right return spring 420, which is then released through the right return spring. Spring 420 resets slider 320. When slider 320 moves to the right inside sliding groove 410, it pushes right push plate 421 to the right and squeezes right reset spring 420. At the same time, it pulls left push plate 421 to stretch left reset spring 420. Then, slider 320 can be reset inside sliding groove 410 by left reset spring 420. Therefore, hose section 100 and hose section 200 can be repeatedly stretched and contracted by rigid pipe section 300 when the engine is vibrating. This allows hose section 100 connected to intercooler and hose section 200 connected to engine to absorb the vibration generated when the engine is running. At the same time, it can save the length of intake pipe and improve the vibration damping effect of intake pipe.

[0031] Please see Figures 1-4 As a second embodiment of this utility model: based on the description in the above embodiments, further, two sets of balls 321 are embedded in the front and rear positions of the lower surface of the slider 320, and the four sets of balls 321 are exactly the same in specifications, and the specifications of the balls 321 match the specifications of the rolling groove 440.

[0032] The interval length between the two sets of ball bearings 321 is matched with the interval length between the two sets of rolling grooves 440, and the left and right sides of the slider 320 respectively abut against the left and right sets of push plates 421.

[0033] In actual use, when the slider 320 slides inside the sliding groove 410, the two sets of balls 321 on the front side of the lower surface of the slider 320 roll inside the front rolling groove 440, and the two sets of balls 321 on the rear side of the lower surface of the slider 320 roll inside the rear rolling groove 440. This makes the slider 320 slide more smoothly and effortlessly inside the sliding groove 410, which in turn makes the movement of the rigid tube section 300 under the frame more sensitive, and makes the extension and retraction of the hose section 100 and hose section 200 more sensitive. This helps to improve the absorption and weakening of engine vibration by the hose section 100 and hose section 200, thereby improving the shock absorption effect of the intake pipe.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
