Description

Technical Field

[0001] This utility model relates to the field of folding vehicles, and in particular to a folding fork assembly for scooters or bicycles. Background Technology

[0002] In folding bicycles and folding scooters, the front upright is usually designed to be foldable in order to minimize the space when folded. However, the tires and frame give the scooter or bicycle a certain length, which also requires a certain amount of space when parked, thus creating storage problems. This is especially true when the scooter is to be placed in a car for transport to a more spacious outdoor area, as the rear storage space is often not high or deep enough to fit the scooter. Therefore, the front fork assembly in the current technology still needs further improvement. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a front fork folding assembly, which solves the problem mentioned in the background art where the front wheel cannot be folded when folding the front column of a folding bicycle or scooter, resulting in insufficient storage space after folding and the inability to put it into the storage space.

[0004] This utility model provides the following technical solution:

[0005] The fork folding assembly includes an eccentric wrench, a connecting rod, a base, and a frame. The eccentric wrench is hinged to one end of the connecting rod, and the other end of the connecting rod passes through the base and is connected to the frame.

[0006] Furthermore, the base is provided with one or more positioning pins on the side near the vehicle frame, and the vehicle frame is provided with positioning grooves corresponding to the positioning pins.

[0007] Furthermore, the frame includes a connecting part and a pedal part, and one end of the connecting part is provided with the positioning groove and connected to the base.

[0008] Furthermore, the positioning pin is wider near the base end and narrower near the frame end.

[0009] Furthermore, there are two positioning pins, and the positioning pins are arc-shaped.

[0010] Furthermore, the connecting rod is fitted with a spring.

[0011] Compared with the prior art, this utility model has the following advantages: When the eccentric wheel of the eccentric wrench rotates, it is in the first position, i.e., the locked position, when the far end of the eccentric wheel abuts against the base; when the near end of the eccentric wheel abuts against the base, it is in the second position. When the near end of the eccentric wheel is against the base, the positioning pin disengages from the positioning groove through the elastic force of the spring, and the frame can rotate around the connecting rod or the base can rotate around the connecting rod, rotating the front wheel above the frame or rotating it in the direction of the frame. The folded volume is smaller, the structure is simple, the folding is convenient, and it is very convenient to carry. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1-6 This utility model proposes a front fork folding assembly, including an eccentric wrench 4, a connecting rod 3, a base 1, and a frame 2. The eccentric wrench 4 is hinged to one end of the connecting rod 3, and the other end of the connecting rod 3 passes through the base 1 and connects to the frame 2. During rotation, the eccentric wheel of the eccentric wrench 4 is in a first position (locked position) when its far end touches the base 1; and in a second position when its near end touches the base 1. With a gap between the base 1 and the frame 2, the frame 2 can rotate around the connecting rod 3, or the base 1 can rotate around the connecting rod 3, causing the front wheel to fold upwards towards the frame 2, resulting in a smaller folding space.

[0024] Furthermore, the base 1 is provided with one or more positioning pins 11 on the side near the frame 2, and the frame 2 is provided with positioning grooves 23 corresponding to the positioning pins 11. In the locked position, the base 1 is positioned to prevent it from sliding, thus enhancing safety.

[0025] Furthermore, the frame 2 includes a connecting part 21 and a foot pedal part 22. One end of the connecting part 21 is provided with the positioning groove 23 to connect with the base 1. The connecting part 21 is on one side of the base 1, which facilitates the rotation of the base 1 without obstruction, making folding more convenient and quick, and reducing the folding space by one-third.

[0026] Furthermore, the positioning pin 11 is wider at the end near the base 1 and narrower at the end near the frame 2. This facilitates the positioning pin 11 sliding in and out of the positioning groove 23.

[0027] Furthermore, there are two positioning pins 11, which are arc-shaped, ensuring accurate positioning and preventing wobbling, thus improving safety during driving.

[0028] Furthermore, a spring is fitted on the connecting rod 3. The spring is located inside the base 1. During the process of the eccentric wrench 4 rotating from the far end to the near end against the base 1, the elastic force of the spring is used to keep the eccentric wrench 4 against the base 1, so that the positioning pin 11 of the base 1 can disengage from the positioning groove 23 of the frame 2.

[0029] The specific implementation method of this embodiment is as follows:

[0030] One end of the eccentric wrench 4 is hinged to the connecting rod 3, and the other end passes through the base 1 and connects to the frame 2. Unlock the eccentric wrench 4 and then rotate it. When the eccentric wheel of the eccentric wrench 4 rotates, the second position is when the near end of the eccentric wheel touches the base 1. The positioning pin 11 of the base 1 disengages from the positioning groove 23 of the frame 2. The frame 2 can rotate around the connecting rod 3 or the base 1 can rotate around the connecting rod 3 to rotate the front wheel above or below the frame 2, resulting in a smaller folded volume. When riding is required, rotate the base 1 to slide the positioning pin 11 into the positioning groove 23, and rotate the eccentric wrench 4. When the far end of the eccentric wheel touches the base 1, the first position, i.e., the locked position, is achieved.
