[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:
[0018] likeFigures 1 to 3 As shown, a front fork hook of an electric bicycle includes two hook bodies 1 installed on the front fork. The hook bodies 1 are made of aluminum alloy through a hot forging process, so that the entire hook body 1 has high tensile strength and wear resistance, can withstand various forces during the driving of the bicycle, and can ensure that the size and shape of the hook are very precise. A columnar through hole 11 for installing components is provided on the surface of each hook body 1. An air pump is installed inside one of the columnar through holes 11. This setting is because some electric bicycles on the market adopt a pneumatic shock absorption structure. Installing the air pump inside the columnar through hole 11 makes the entire electric bicycle have better integrity and integration. Of course, the air pump also needs to be connected to the pneumatic rebound shock absorption structure of the bicycle. Of course, an oil pump is installed inside the other columnar through hole 11, and the oil pump is used to control the rebound speed of the pneumatic rebound shock absorption. After such a setting, for electric bicycles with pneumatic shock absorption products, the function of pneumatic shock absorption can be better realized by using the columnar through hole 11, and pneumatic shock absorption can improve driving comfort, enhance safety and improve passability. Pneumatic shock absorption uses an airbag instead of a spring. The sensitivity of the airbag is higher than that of the spring, and it can more effectively filter out the bumps on the road surface and improve driving comfort.
[0019] In the present embodiment, a first mounting groove 12 is provided on one side of each hook body 1, and a first avoidance groove 13 is further provided inside each first mounting groove 12. It should be noted that the cross section of the first avoidance groove 13 is U-shaped, and the U-shaped shape allows the user to have better guidance and support during installation. The first avoidance groove 13 runs through the entire first mounting groove 12, and the front wheel axle of the bicycle passes through each first avoidance groove 13. A first columnar fixing member 14 and an inclined support column 15 are further provided on one side of at least one hook body 1, and a first columnar fixing member 14 is also provided at one end of the inclined support column 15. After such arrangement, the two first columnar fixing members 14 are connected to the brake on the bicycle, thereby maximizing the integration and degree of integration of the entire electric bicycle. A first countersunk hole 16 is further provided on one side of each first mounting groove 12, and a first fixing hole 17 is provided inside each of the first countersunk hole 16 and the first avoidance groove 13. , the external bolt passes through the first fixing hole 17, and after the external bolt is installed in the first fixing hole 17, its nut is basically sunken in the first countersunk hole 16, which is not easy to have excessive impact on the bolt when driving on some complex roads. Therefore, the bolt can also prevent falling off during daily use. A limiting groove 18 is provided on one side of each of the first mounting grooves 12, and the cross street of the limiting groove 18 is also U-shaped. The cross-sectional area of the limiting groove 18 is larger than the cross-sectional area of the first avoidance groove 13, wherein the setting of the limiting groove 18 is to play an avoidance or limiting role when installing the front wheel axle, and for the front wheel axle of the electric bicycle, the bearing can be installed in the area of the first mounting groove 12, and the front wheel axle is stuck in this bearing shaft, and then the external bolt passes through the inside of the first fixing hole 17, so that the bearing matched with the front wheel axle is firmly stuck, and this mounting structure can also withstand this area without large shaking.
[0020] Working principle and usage of this utility model:
[0021] The surface of the hook body 1 has a columnar through hole 11 for installing parts, and an air pump is installed inside one of the columnar through holes 11. This setting is because some electric bicycles on the market use a pneumatic shock-absorbing structure. The air pump is installed inside the columnar through hole 11, which makes the entire electric bicycle have better integrity and integration. Of course, the air pump is also connected to the pneumatic rebound shock-absorbing structure of the bicycle. Of course, an oil pump is installed inside the other columnar through hole 11, and the oil pump is used to control the rebound speed of the pneumatic rebound shock-absorbing. After this setting, for electric bicycles using pneumatic shock-absorbing products, The columnar through hole 11 can better realize the function of pneumatic shock absorption; one end of the inclined support column 15 has a first columnar fixing piece 14, and the two first columnar fixing pieces 14 are connected to the brakes on the bicycle. The hook body 1 has a first mounting groove 12. For the front wheel axle of the electric bicycle, the bearing can be installed in the area of the first mounting groove 12, and the front wheel axle is stuck inside this bearing shaft, and then the external bolt passes through the inside of the first fixing hole 17, so that the bearing matched with the front wheel axle is firmly stuck. This installation structure can also withstand this area without causing large shaking.
