Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the utility model provides a shock absorbing front fork assembly, which comprises a fork leg 1 and a shock absorbing part, wherein the shock absorbing part comprises a connecting piece 6, a hook claw 2 and a spring 3; one end of the connecting piece 6 is connected with the end part of the fork leg 1, and the other end is connected with one end of the hook claw 2 in a rotating way: the connecting piece 6 tends to form an included angle with the hook claw 2, the spring 3 is arranged between the connecting piece 6 and the hook claw 2, and the connecting piece 6, the hook claw 2 and the spring 3 are integrally formed into a triangular shape. Collude the position that claw 2 can be in under connecting piece 6, and can form the structure that sets up relatively between the two, through set up spring 3 between the two to make spring 3 tend to vertical state, thereby make collude claw 2 and can be in on the best stress position, then make when colluding the claw 2 atress can be more timely and sensitive make use to rotate the junction to extrude spring 3 and reach the effect of moving away to avoid possible earthquakes as the rotation center upwards activity, and make whole structure more succinct compact.

Referring to fig. 4-5, one end of the hook claw 2 is provided with a connecting lug 201, a mounting groove 601 is arranged below the end part of the connecting piece 6, the connecting lug 201 is inserted into the mounting groove 601, the connecting lug 201 rotates in the mounting groove 601 through a pin shaft 4, the mounting groove 601 can provide a containing space for the connecting part of the hook claw 2 and the connecting piece 6, and then the movement of the hook claw 2 and the shock absorption effect are prevented from being influenced by external invasion; one surface of the mounting groove 601, which is far away from the spring, limits the moving angle of the hook claw 2 to form a limiting abutting surface 61 so as to prevent the free end of the hook claw 2 from rotating towards the end direction of the pin shaft 4; the connecting piece 6 is provided with a first groove 602, the hook claw 2 is provided with a second groove 202, and two ends of the spring 3 are respectively embedded in the first groove 602 and the second groove 202. Through mounting groove 601 and butt face, make connecting piece 6 and collude and tend to the contained angle between the claw 2, prevent to collude claw 2 and 6 contained angles of connecting piece too big, the both ends of spring 3 only need be through the recess inlay card, and guarantee spring 3 does not deviate from the recess. The connection at 3 both ends of spring does not need other parts, makes installation, dismantlement convenient fast, can also lighten automobile body weight, and is lighter.

The spring 3 is in a vertical state, or tends to be in a vertical state. So that the hook claw 2 can be positioned at the best stress position, and then the hook claw 2 can be more timely and sensitively stressed to move upwards to extrude the spring 3 by taking the rotating joint as a rotating center to achieve the shock-absorbing effect, and the whole structure is more concise and compact.

Specifically, the method comprises the following steps: the cross sections of the first groove 602 and the second groove 202 are circular to adapt to the size of the spring, the bottoms of the first groove 602 and the second groove 202 are arc surfaces, and when the spring is compressed to generate micro displacement in the first groove 602 and the second groove 202, the arc design ensures that the movement is smoother. When the spring 3 is compressed by force, the first groove 602 and the second groove 202 can accommodate the compressed spring 3, so that the distance between the connecting piece 6 and the hook claw 2 constitutes the maximum compression amount of the spring 3.

Collude claw 2 and have bayonet 21 of connecting the front wheel pivot, it is specific: the bayonet 21 is located right below the spring 3 and is used for connecting with a tire shaft.

The end of the connecting piece 6 is provided with a through hole penetrating through the mounting groove 601, the pin shaft 4 comprises a shaft sleeve 41, a first fastening bolt 42 and a second fastening bolt 43, and the shaft sleeve 41 is positioned in the through hole and penetrates through the hook claw 2; the first fastening bolt 42 and the second fastening bolt 43 are oppositely arranged at two ends of the shaft sleeve 41 and are respectively in threaded connection with the shaft sleeve 41, and the heads of the first fastening bolt and the second fastening bolt are respectively abutted against the connecting piece 6 to form limiting. When the fork is disassembled, the hook claw 2 can be separated from the fork leg 12 only by unscrewing the first fastening bolt 42 and the second fastening bolt 43 at the two ends of the shaft sleeve 41; in the mounting, the first fastening bolt 42 and the second fastening bolt 43 may be tightened again. The whole structure is simpler, and the installation is more convenient.

Referring to fig. 6, the utility model discloses a scooter, including tire, frame and standpipe, still include foretell fork subassembly before taking precautions against earthquakes, fork leg 1 is fixed in the one end of standpipe 5.
