Abstract

The invention provides a water tank mounting structure of a motorcycle engine, and belongs to the technical field of motorcycles. The problem that the heat radiation efficiency of a water tank of an existing motorcycle engine is low is solved. According to the water tank mounting structure of the motorcycle engine, the engine comprises a cylinder body; a fan is arranged on the cylinder body; the mounting structure comprises a plate-shaped support fixed to the cylinder body; a ventilation hole opposite to the fan is formed in the support; a water tank is fixed to the outer side face of the support and is opposite to the ventilation hole; two parallel sealing grooves are formed in the outer side face of the support; two parallel sealing flanges are further arranged on the outer side face ofthe support; the two sealing grooves and the two sealing flanges define a rectangle; the two ends of the water tank are provided with sealing convex edges, and the two sealing convex edges are embedded into the two sealing grooves to for sealing; and the two sealing flanges are opposite to the two sides of the water tank correspondingly, and sealing is formed. The heat radiation efficiency of thewater tank of the motorcycle engine is higher.

Example Embodiment

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
[0030] like figure 1 , figure 2 , image 3 As shown, a water tank 4 installation structure for a motorcycle engine, the engine includes a cylinder block 1, a crankshaft 12 is arranged in the cylinder block 1, one end of the crankshaft 12 protrudes from the cylinder block 1, and the protruding end of the crankshaft 12 is The fan 2 is fixed, and the installation structure includes a bracket 3 fixed on the cylinder block 1. The bracket 3 is in the shape of a rectangular plate, and the fan 2 is located inside the bracket 3, that is, the fan 2 is located between the bracket 3 and the cylinder block 1. A ventilation hole 31 is opened in the middle, and the fan 2 is opposite to the ventilation hole 31. The outer diameter of the fan 2 is slightly smaller than the aperture of the ventilation hole 31. A water tank 4 is fixed on the outer surface of the bracket 3. 4 is opposite to the ventilation hole 31 . combine Figure 4 As shown, there are a pair of sealing ribs 32 along the length direction at the opposite two edges of the outer side of the bracket 3, and a sealing groove 33 is formed between the two sealing ribs 32 of the same pair, and the two sealing grooves 33 are arranged in parallel. 3. There are also two parallel sealing flanges 34 on the outer side. The sealing flanges 34 are perpendicular to the outer side of the bracket 3. The two sealing grooves 33 and the two sealing flanges 34 are perpendicular to each other and form a rectangle. The two ends of the inner sealing rib 32 of the rib 32 respectively extend to butt joint with the ends of the two sealing flanges 34, and are combined with each other. Figure 5 , Image 6 As shown, the sealing groove 33 is filled with the sponge 5, and the inner side edges of both ends of the water tank 4 have sealing protruding edges 41 along the length direction. The water tank 4 is located between the two sealing flanges 34, and the two side edges of the water tank 4 are respectively opposite to the two sealing flanges 34. The sponge 5 is filled between the edge of the water tank 4 and the sealing flanges 34, and the inner side of the water tank 4 is opposite to the two sealing flanges 34. There is a gap between the outer sides of the bracket 3 , and a sponge 5 is filled between the inner side of the water tank 4 and the outer side of the bracket 3 .
[0031] The cylinder block 1 is provided with a number of support columns 11, and the inner side of the bracket 3 is vertically provided with a number of connection columns 35. The connection columns 35 are respectively connected with the support columns 11 one by one, and are connected through bolts, and the support columns 11 are connected to the connection columns. 35 supports so that there is space between the bracket 3 and the cylinder block 1, combined with Figure 7 As shown, there are several front guide fins 36 and several rear guide fins 37 vertically on the inner side of the bracket 3, the several front guide fins 36 are located on the front side of the fan 2, the several front guide fins 36 are arranged in parallel, and A front guide channel 361 is formed between two adjacent front guide plates 36 , and the front end of the front guide channel 361 is inclined downward. A plurality of rear guide fins 37 are located on the rear side of the fan 2 , and the plurality of rear guide fins 37 are arranged in parallel, and a rear guide channel 371 is formed between two adjacent rear guide fins 37 , and the rear end of the rear guide channel 371 is formed. The horizontal arrangement is rearward, and then the guide channel 371 can also be slightly inclined. The rear side of the bracket 3 is also vertically provided with a long baffle 38. The baffle 38 is located on the upper side of the fan 2. The baffle 38 is arc-shaped, and the baffle 38 is arranged along the upper edge of the ventilation hole 31. The front end of the baffle 38 is in contact with the rear end of the uppermost front guide fin 36, and the front end of the baffle 38 and the rear end of the front guide fin 36 smoothly transition, and the rear end of the baffle 38 is located above the uppermost rear guide fin 37 .
[0032] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which the present invention pertains can make various modifications or additions to the described specific embodiments or substitute in similar manners, but will not deviate from the spirit of the present invention or go beyond the definitions of the appended claims range.
[0033] Although the terms such as the cylinder block 1, the support column 11, the crankshaft 12, etc. are often used herein, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the nature of the present invention; it is contrary to the spirit of the present invention to interpret them as any kind of additional limitation.
