Description

Technical Field

[0001] This application relates to the field of electric vehicle technology, and in particular to a waterproof fork shoulder box. Background Technology

[0002] In today's transportation landscape, electric bikes, with their environmentally friendly, convenient, and efficient characteristics, have become the preferred choice for more and more people's daily travel, whether for commuting, shopping, or everyday transportation. The front fork seat tube in a bicycle primarily serves to provide support and balance adjustment.

[0003] Chinese utility model patent CN221852102U discloses a fork shoulder box and its fixing structure, including a fork shoulder, a fork shoulder box bracket, and a fork shoulder box. Two limiting posts for limiting and positioning the fork shoulder box extend upward from the top surface of the fork shoulder. The fork shoulder box bracket welded to the fork shoulder includes a side plate, a top plate, and lugs. The side plate, which is positioned and attached to the side wall of the fork shoulder, is a C-shaped plate structure. The top surfaces of the two ends of the side plate are bent and connected to L-shaped top plates perpendicular to them. The two top plates are symmetrically provided with first bolt holes extending through their thickness. The outer sides of the two top plates are connected to downward bent lugs, and the bottom surfaces of the lugs are supported on the top surface of the fork shoulder. The fork shoulder box is a box structure that is fastened to the fork shoulder and has an open bottom. Its top surface is provided with a fork riser hole, a limiting hole, and a second bolt hole. The fork shoulder box is fixedly installed on the fork shoulder by screwing bolts into the first bolt holes of the fork shoulder box bracket and the second bolt holes of the fork shoulder box.

[0004] In actual use, when rainwater falls into the fork shoulder box, the fork shoulder box cannot block it well. The rainwater flows to the fork shoulder. The fork tube and fork riser are both installed on the fork shoulder. The soaking of rainwater makes the connection between the fork tube and fork riser and the fork shoulder prone to rust and corrosion, which affects the riding safety of electric vehicles.

[0014] By adopting the above technical solution, the positioning column and positioning groove make the installation of the fork shoulder box easier and easier to position.

[0015] Optionally, the fork shoulder piece has two threaded holes, the fork shoulder box has a through hole, and a fixing bolt is also included. A waterproof gasket is fitted on the fixing bolt, and the fixing bolt passes through the through hole and is threaded into the threaded hole.

[0016] By adopting the above technical solution, the fork shoulder box is fixed to the fork shoulder piece by fixing bolts, which further improves the installation firmness of the fork shoulder box, and the waterproof gasket prevents rainwater from entering the fork shoulder piece.

[0017] Optionally, a cover is inserted into the bottom of the fork shoulder box, and the cover has a connecting hole for the fork tube to pass through.

[0018] By adopting the above technical solution, the cover improves the sealing performance of the fork-shoulder box.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. A waterproof sleeve is fitted onto the fork riser. The waterproof sleeve and waterproof gasket improve the sealing of the fork shoulder box, making it difficult for rainwater to flow from the through hole to the fork shoulder, thus improving the waterproof performance of the fork shoulder box.

[0021] 2. The waterproof sleeve is threaded to the annular sleeve block, ensuring a secure installation and good waterproof performance;

[0022] 3. The lid improves the sealing of the fork-shoulder box. Attached Figure Description
