DETAILED DESCRIPTION

[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] See also Figure 1 - Figure 6 , the present application provides an automobile water pump structure, comprising:

[0041] The water pump body 100 includes a pump housing 101 , and a pump shaft 104 is disposed inside the pump housing 101 ;

[0042] The chip removal structure 200 installed at the lower end of the pump shaft 104 can fully stir the coolant entering the separation cylinder 201 to allow the iron chips in the coolant to move fully, and can also use the magnetic attraction component to adsorb the used iron chips, so that the iron chips will not enter the water pump with the coolant to cause wear, thereby increasing the working stability and safety of the water pump body 100, and is used to remove the iron chips in the coolant;

[0043] The chip removal structure 200 includes a driving stirring member 204 connected to the lower end of the pump shaft 104 to disperse the coolant entering the separation cylinder 201. The separation cylinder 201 is installed at the bottom of the water pump body 100 by screw sleeves, and a sealing ring and waterproof glue can be filled between the two for sealing;

[0044] The chip removal structure 200 includes a side magnetic attraction member 205 located below the driving stirring member 204 and used for magnetically attracting iron chips in the coolant, so as to absorb the stirred and flowing iron chips.

[0045] In this embodiment, preferably, the lower end of the pump shaft 104 is connected to a connecting shaft 203, and the two are connected by screws for easy disassembly and assembly. A central magnetic attraction component 208 is sleeved on the connecting shaft 203. The structure of the central magnetic attraction component 208 is the same as that of the side magnetic attraction component 205, but the size is different. In order to adapt to the different diameters of the connecting shaft 203 and the side mounting shaft 2043, the driving stirring component 204 includes a central gear 2041 sleeved on the upper end of the connecting shaft 203, and side gears 2042 are respectively engaged on both sides of the central gear 2041. Arc holes are provided on the surfaces of the central gear 2041 and the side gear 2042 to reduce the resistance to the flow of coolant. A side mounting shaft 2043 is vertically arranged inside the side gear 2042, and a stabilizing plate 2044 supporting both ends of the side mounting shaft 2043 is horizontally arranged on the inner surface of the separation cylinder 201.

[0046] In this embodiment, preferably, the side magnetic attraction component 205 includes a protective shell 2051 sleeved on the side mounting shaft 2043, the protective shell 2051 protects the magnetic attraction ring 2052, and at the same time, the protective shell 2051 does not affect the magnetic attraction effect of the magnetic attraction ring 2052, a magnetic attraction ring 2052 is embedded between the protective shell 2051 and the side mounting shaft 2043, a mounting ring 2053 is sleeved on the protective shell 2051, and a stirring blade 2054 is arranged on the circumferential surface of the mounting ring 2053, and the stirring blade 2054 is arranged on the circumferential surface of the mounting ring 2053. 54 can rotate with the side mounting shaft 2043, and the two stirring blades 2054 rotate in opposite directions, which increases the stirring effect on the coolant. Sleeves 2055 are provided at the upper and lower ends of the protective shell 2051. The sleeve 2055 is fixed on the side mounting shaft 2043 by installing screws 2057 to realize the detachable connection of the entire side magnetic attraction component 205. A sealing ring 2056 is embedded in the sleeve 2055, and the sealing ring 2056 can fill and seal the gap between the sleeve 2055 and the connecting shaft 203.

[0047] In summary, the chip removal structure 200 is installed at the bottom of the water pump body 100. When the water pump body 100 is working, the pump shaft 104 rotates synchronously with the impeller 103, driving the connecting shaft 203 and the central gear 2041 thereon to rotate, and the side gears 2042 meshing therewith on both sides rotate synchronously, driving the two side mounting shafts 2043 to rotate, and driving the two stirring blades 2054 on the side mounting shafts 2043 to rotate in the opposite direction, breaking up the columnar coolant entering the separation cylinder 201, allowing the iron filings inside to flow outward. The iron filings flow outward with the coolant to easily and fully contact the protective shell 2051. The magnetism of the magnetic ring 2052 allows the iron filings to be adsorbed on the outer surface of the protective shell 2051, and breaking up the coolant will prolong the retention time of the coolant in the separation cylinder 201, thereby improving the removal effect of the iron filings in the coolant. When the adsorption reaches a certain level and needs to be cleaned, the chip removal structure 200 is disassembled and removed, and the surface of the protective shell 2051 can be cleaned.

[0048] Embodiment 2

[0049] Reference Figure 7 , which is the second embodiment of the present invention.

[0050] In this embodiment, preferably, a water inlet pipe 202 is provided on the lower surface of the separation cylinder 201, and a flow regulating component 206 for regulating the flow of the upper end of the water inlet pipe 202 is provided at the lower end of the connecting shaft 203. By providing the flow regulating component 206, the flow of the coolant entering the separation cylinder 201 can be regulated and restricted to avoid the situation where more coolant continues to enter and the impurities are not thoroughly removed, thereby improving the coolant impurity removal effect, and the blocking area of ​​the liquid inlet can be adjusted, thereby expanding the scope of use and increasing the convenience of adjustment. The flow regulating component 206 includes three adjusting rings 2061 rotatably sleeved on the lower end of the connecting shaft 203, and the three adjusting rings 2061 are The adjusting fan-shaped plates 2063 are arranged horizontally on the outer circumference of the adjusting ring 2061, and the fan-shaped area of ​​the adjusting fan-shaped plates 2063 can be designed and adjusted according to the diameter of the water inlet pipe 202, and the number can also be adaptively adjusted according to the needs. The outer end of the adjusting fan-shaped plate 2063 exceeds the diameter of the water inlet pipe 202, which is convenient for covering the water inlet pipe 202. A limiting bolt 2062 is arranged between the adjusting ring 2061 and the connecting shaft 203, and the limiting bolt 2062 can be used to limit and fix the angle of the adjusting fan-shaped plate 2063 on the adjusting ring 2061.

[0051] In summary, during assembly, according to the amount of coolant entering, the limit bolt 2062 can be loosened to allow the adjusting ring 2061 to rotate around the connecting shaft 203 and adjust the position of the fan plate 2063. According to this operation, the angles of the three adjusting rings 2061 are adjusted in turn, thereby adjusting the overlapping angles of the three adjusting fan plates 2063 to change the blocking area of ​​the water inlet pipe 202. When the three adjusting fan plates 2063 are completely overlapped, the blocking area of ​​the water inlet pipe 202 is the smallest. Conversely, when the three adjusting fan plates 2063 are fully unfolded, the blocking area of ​​the water inlet pipe 202 is the largest. When the blocking area of ​​the water inlet pipe 202 is appropriate, as the pump shaft 104 rotates, a part of the pipe mouth is always blocked during the rotation process, thereby reducing the amount of coolant entering and avoiding the situation where too much coolant continues to enter and impurities are not thoroughly removed.

[0052] Embodiment 3

[0053] Reference Figure 8 , which is the third embodiment of the present invention.

[0054] In this embodiment, preferably, the lower end surface of the connecting shaft 203 is provided with a filter component 207 extending to the inside of the water inlet pipe 202. By providing the filter component 207, the inflowing coolant can be initially filtered to prevent large particles of impurities from entering the inside of the water pump and causing wear. As the pump shaft 104 rotates, the arc plate 2073 can be driven to scrape the filter surface of the filter plate 2072, so that impurities will not always block the filter holes, thereby achieving continuous and stable filtration of the coolant. The filter component 207 is used to filter the incoming coolant. The filter component 207 includes two filter plates 2072 horizontally installed in the water inlet pipe 202. The lower end of the connecting shaft 203 is provided with a rotating filter that penetrates the two filter plates. The fixing rod 2071 of 2072 and the connecting shaft 203 are connected to the fixing rod 2071 by screws, which is convenient for the disassembly and assembly of the two. The rotation of the fixing rod 2071 will not conflict with the filter plate 2072. The circumferential surface of the fixing rod 2071 is provided with a toggle arc plate 2073 located on the lower surface of the filter plate 2072, which is convenient for scraping off impurities on the lower surface of the filter plate 2072 and will not be retained in one place to block the filter holes. The lower end of the fixing rod 2071 is sleeved with a support ring 2074, and a bearing is embedded between the two, which does not affect the rotation of the fixing rod 2071. A plurality of support rods 2075 are provided between the support ring 2074 and the water inlet pipe 202, which play a supporting role for the support ring 2074 and the fixing rod 2071.

[0055] In summary, when the fixed rod 2071 rotates synchronously with the connecting shaft 203, the moving arc plate 2073 on the fixed rod 2071 will be driven to rotate. The moving arc plate 2073 contacts the lower surface of the filter plate 2072. As it rotates, the debris particles trapped on the lower surface of the filter plate 2072 will be pushed outward, and will not be trapped on the surface of the filter plate 2072 and cause blockage. As the moving arc plate 2073 rotates, the particles on the filter plate 2072 are continuously scraped off, so that the filter holes on the filter plate 2072 are always kept unobstructed, thereby increasing the stability and smoothness of the coolant circulation.

[0056] In this embodiment, preferably, the lower end of the pump shaft 104 is sleeved with an impeller 103 located in the separation barrel 201 , and a pump cover 102 is provided on the pump housing 101 .

[0057] Embodiment 4

[0058] Based on the water pump structures in Embodiment 1, Embodiment 2 and Embodiment 3, a production process of an automobile water pump structure is obtained;

[0059] S1. Design: design the various parts of the water pump into the required shape and size;

[0060] S2, raw material preparation, prepare all the materials needed for each component in S1, and the materials must meet standard specifications;

[0061] S3, material processing, cutting, casting, stamping and other processes are performed on the materials in S2 to process the materials into the designed shape and size;

[0062] The parts processed in S4 and S3 are inspected and assembled, and the assembled water pump is debugged. During the debugging process, it is determined whether the water pump body 100 can work normally. If the water pump body 100 works normally, the filter component 207 is used to preliminarily filter the incoming coolant, and the amount of the filtered coolant entering is adjusted by the flow regulating component 206. The pump shaft 104 will drive the connecting shaft 203 to rotate, thereby driving the driving stirring component 204 to work, and the coolant entering the separation cylinder 201 in a columnar and regular shape is stirred, so that the iron filings inside the coolant flow outwards and are conveniently adsorbed and removed. While stirring the coolant, the side magnetic attraction component 205 and the central magnetic attraction component 208 are used to adsorb and remove the iron filings in the coolant, thereby increasing the degree of cleaning of the iron filings in the coolant;

[0063] S5. Treat the surface of the debugged water pump and finally package the water pump.
