Embodiment
It is as shown in Figures 2 and 3: a kind of fixed structure of rear wheels of electric vehicle provided by the utility model, including rear-wheel 1, after
The two sides of wheel 1 are respectively equipped with rear chainstay 2, and chain stay central siphon 3 is connected between rear chainstay 2, is rotatably equipped with rear-wheel in rear-wheel 1
Axis 4, the two sides of the rear-wheel 1 are respectively equipped with installation round tube 5, and the installation round tube 5 is sheathed on the outer wall of hind axle 4, after described
One end of chainstay 2 is connected with chain stay central siphon 3, and the other end is connected with installation round tube 5.
When fixed rear wheels of electric vehicle being installed using above-mentioned fixed structure:
First hind axle 4 is rotatablely installed in rear-wheel 1, is then arranged with installation round tube 5 respectively at the both ends of hind axle 4,
Each installation round tube 5 is respectively connected with rear chainstay 2, and the remaining one end of rear chainstay 2 is connected with the both ends of chain stay central siphon 3 respectively,
To rear-wheel 1 is installed in rear chainstay 2.
In conjunction with Fig. 1 to Fig. 3 and above-mentioned installation process as it can be seen that the fixed structure of current rear wheels of electric vehicle, is to pass through metal plate
Rear-wheel 1 is installed in rear chainstay 2 (as shown in Figure 1) by part 6, and the utility model is to be installed rear-wheel 1 by installation round tube 5
In in rear chainstay 2 (as shown in Figures 2 and 3), hind axle 4 is mounted in installation round tube 5, installs 5 all directions stress of round tube
Uniformly, it is not susceptible to deform, higher integral strength, and reliability is preferable；And since installation round tube 5 is directly to be set in hind axle
On 4, when installation, directly installation round tube 5 is set on hind axle 4, it can be easy for installation with once mounting in place；
In addition, since hind axle 4 is provided in installation round tube 5, even if the electric vehicle after installation is used for a long time, Chinese herbaceous peony rear-wheel
Wheelbase can also be kept fixed it is constant, so as to avoid because rear-wheel it is eccentric caused by drive risk, safety is good；In addition, phase
Compared with traditional sheet metal component 6, installing round tube 5, not only volume is light and handy, and hind axle 4 can be protruded part and remaining mounting assembly
It is hidden in installation round tube 5, so that vehicle overall appearance coordinates beauty.
As a preferred solution:
As shown in figure 3, the inner side end of the installation round tube 5 is equipped with sealing plate 7, the sealing plate 7 is equipped with and 4 phase of hind axle
The mounting hole 71 of adaptation, the hind axle 4 pass through the mounting hole 71 on sealing plate 7 and are connected with installation round tube 5, play to hind axle 4
Fixed effect is limited, hind axle 4 is can avoid and shakes.
Offer notch 51 compatible with 4 outer diameter of hind axle on the installation round tube 5, the notch 51 can on sealing plate 7
Mounting hole 71 connect, the peace that hind axle 4 need to be only pushed into from the notch 51 on installation round tube 5 when assembly on the sealing plate 7
71 position of hole is filled, is installed on hind axle 4 in installation round tube 5, it is more convenient to install, while can reduce chainstay 2 behind two sides
The distance between, make more compact structure.
The opening direction of the notch 51 is downward, installation round tube 5 is directly placed on hind axle 4 when assembly, or will
Hind axle 4 is put into installation round tube 5, and easy for installation, simultaneously because the opening direction of notch 51 is downward, hind axle 4 is being installed
Round tube 5 not will shake left and right, though be used for a long time, the wheelbase of Chinese herbaceous peony rear-wheel can also be kept fixed it is constant, so as to avoid
Because driving risk caused by rear-wheel bias, safety is good.
The fixed structure further includes limit film 8, the limit film 8 be sheathed on the outer wall of hind axle 4 and with installation round tube 5
Inner wall be adapted, further position-limiting action played to hind axle 4, and then can avoid hind axle 4 and shake, improves fixed structure
Whole stability.Further, the outer ring of the limit film 8 is equipped with the limiting section 81 of protrusion, limiting section 81 and installation round tube 5
Notch 51 be adapted, can further limit the rotation of hind axle 4, keep structure more reliable.
The fixed structure further includes locking member 9, and the locking member 9 is sheathed on the outer wall of hind axle 4, is risen to hind axle 4
It is acted on to locking, to further increase the stability of fixed structure entirety.The locking member 9 is using locking member general in the market
, such as in the present embodiment locking member 9 uses locking nut (specifically for flange nut), to lock nut, rear-wheel
The both ends outer wall of axis 4 can be equipped with thread (not shown) compatible with locking nut, and hind axle 4 passes through the mounting hole on sealing plate 7
71 and installation round tube 5 and by locking nut can be realized hind axle 4 and installation round tube 5 between being detachably connected so that after
It is dismounted between wheel shaft 4 and installation round tube 5 more convenient.
As shown in figure 3, limit film 8 can be set to sealing plate 7 and locking member when being equipped with sealing plate 7, limit film 8 and locking member 9 simultaneously
Between 9.
In addition, in order to further increase the compactness installed between each component and stability, 4 both ends of hind axle are equipped with
Flat horizontal surface 41 is milled, the diameter of axle size in the present embodiment, at milling flat horizontal surface 41 set by the mounting hole 71 and hind axle 4 on sealing plate 7
It is adapted, can be limited in this way by the cooperation of mounting hole 71 on the diameter of axle and sealing plate 7 at milling flat horizontal surface 41 set by hind axle 4
The rotation of hind axle 4 processed.
As shown in figure 3, the inside of the locking member 9 is equipped with elastic washer 10, the elastic washer 10 is sheathed on hind axle 4
Outer wall, can effectively prevent in this way locking member 9 loosening, connect locking member 9 with hind axle 4 more solid and reliable.
In addition, the end of the installation round tube 5 in the present embodiment can be equipped with end cap (not shown), so as to by hind axle
4 protrusion and remaining component (such as: locking member 9) it is hidden in installation round tube 5, to improve the beauty of vehicle entirety
The property seen can also make the decorations such as upper logo mark on end cap, keep vehicle appearance more attractive.
In addition, in the present embodiment, rear chainstay 2 and chain stay central siphon 3 can use between rear chainstay 2 and installation round tube 5
