[0028] like Figures 3 to 5 As shown, the specific structure of the flexible oil pump suction pipe assembly according to the preferred embodiment of the present invention includes: a flexible suction pipe 21 and a pipe clamp assembly 30, one end of the flexible suction pipe 21 is connected to the oil pump, and the other end is fixed to the bottom of the oil pan through the pipe clamp assembly, so as to be immersed in the oil in the oil pan, and the suction port below the other end is close to the bottom of the oil pan. Under the suction action of the oil pump, the oil at the bottom of the oil pan enters the oil pump through the suction pipe. The suction pipe of the flexible oil pump suction pipe assembly is a flexible structure, and the length and angle of the pipeline can be freely adjusted in three dimensions, so that one suction pipe component can match a variety of oil pans of different depths and shapes, thereby improving the adaptability of the suction pipe, and realizing that one suction pipe meets the matching needs of multiple different models, and the production and assembly efficiency is high.

[0029] Specifically, if Figure 4As shown, the flexible oil suction pipe 21 includes: an oil suction pipe body, and an oil pump connector 22 and an oil suction end 24 respectively arranged at both ends of the oil suction pipe body, wherein the oil suction pipe body is a corrugated pipe, which is fixed to the bottom of the oil pan by a pipe clamp assembly, so that the length and angle of the pipeline can be freely adjusted in three dimensions, so that one oil suction pipe component can match a variety of oil pans of different depths and shapes, thereby improving the adaptability of the oil suction pipe. The oil pump connector 22 is arranged at one end of the oil suction pipe body, and is used to connect with the oil pump, so that the oil at the bottom of the oil pan enters the oil pump through the oil suction pipe under the suction action of the oil pump. The oil suction end 24 is arranged at the other end of the oil suction pipe body, and an oil suction port close to the bottom of the oil pan is opened at the bottom thereof, so that under the suction action of the oil pump, the oil at the bottom of the oil pan enters the oil suction pipe body through the oil suction port, and then enters the oil pump.

[0030] In one embodiment, if Figure 3 As shown, the oil suction pipe body includes: a vertical section bellows 25, a bend pipe 26 and a transverse section bellows 27. The vertical section bellows 25 is connected to the transverse section bellows 27 through the bend pipe 26. The transverse section bellows 27 is fixed to the bottom of the oil pan through a pipe clamp assembly. The oil suction end 24 is fixed to the outer end of the transverse section bellows 27 so as to be immersed in the oil in the oil pan. Under the suction action of the oil pump, the oil at the bottom of the oil pan enters the oil pump through the oil suction pipe.

[0031] In one embodiment, the oil suction end 24 is disc-shaped, and an oil suction port is provided at the bottom. The oil suction port is close to the bottom of the oil pan, so that the oil at the bottom of the oil pan can be easily introduced into the oil suction pipe body. The oil suction end 24 is disc-shaped, which increases the volume of the oil suction end of the flexible oil suction pipe 21 and stabilizes the suction flow rate of the oil pump.

[0032] like Figure 5 As shown, the pipe clamp assembly 30 includes: a pipe clamp 31, a fixing bolt 32 and a cushion block 33. The oil suction pipe body is fixed to the cushion block 33 through the pipe clamp 31 and the fixing bolt 32. The cushion block 33 is made of strong magnetic material and is adsorbed on the bottom surface of the stamped steel plate oil pan, so that the oil suction pipe body is fixed to the bottom of the oil pan, so that the oil suction end 24 is immersed in the oil in the oil pan, and the oil suction port below it is close to the bottom of the oil pan. Under the suction action of the oil pump, the oil at the bottom of the oil pan enters the oil pump through the oil suction pipe.

[0033] In one embodiment, the shape of the pipe clamp 31 is an "Ω" shape, which is composed of a first rubber pad, a frame and a second rubber pad from the outside to the inside, and grooves are uniformly arranged on the inner surface of the second rubber pad in the axial direction.

[0034] In one embodiment, the frame is a multi-layer laminated structure, so as to improve the overall strength of the frame. The elastic sealing layer is wrapped around the periphery of the frame of the multi-layer laminated structure.

[0035] In one embodiment, the multiple layers of the frame are fixed by spot welding.

[0036] In one embodiment, a plurality of through holes are formed in the multilayer board of the skeleton, and the whole is fixed by snap-fitting with a ferrule. The cross-section of the ferrule is in a "C" shape. While extending into the through holes of the multilayer board of the skeleton, the two ends are flanged and clamped the multilayer board from both ends, which can play a clamping role in the whole skeleton, making the combination stability of the multilayer board of the skeleton higher, avoiding the situation of delamination of the multilayer board of the skeleton, and thus affecting the fixing effect on the oil suction pipe body.

[0037] In summary, the oil suction pipe of the flexible oil pump oil suction pipe assembly is a flexible structure, which can freely adjust the pipeline length and angle in three dimensions, so as to realize that one oil suction pipe component can match oil sumps with multiple different depths and shapes, improve the adaptability of the oil suction pipe, and realize that one oil suction pipe can meet the supporting requirements of multiple different vehicle models, with high production and assembly efficiency. At the same time, the oil suction pipe is adsorbed on the bottom surface of the stamping steel oil sump through a pad of a strong magnetic material, so as to fix the oil suction pipe body at the bottom of the oil sump, which is convenient for layout and improves the assembly efficiency.
