Embodiment 1

[0036] Embodiment 1, a kind of fuse for two-wheel and three-wheel electric vehicle protection, such as figure 1 , 2 , 3, 4, 5, 6, 7, 8, 9, and 10, 1 is the connecting wire; 2 is the fastening bolt; 3 is the front protective seat cover; 4 is the line perforation sealing ring; 5 is the fuse; 6 For protecting the seat cover interface sealing ring; 7 is the back protection seat cover.

[0037] Installation and use step 1: First insert the connecting wire 1 and the connecting end of the fuse body 5 into the wire socket 522 of the contact 502, and then use the wire fixing bolt 523 to penetrate into the wire fixing threaded hole 521 and use a screwdriver or a torque wrench to tighten the bolt 523 Tighten down, so that the lower end of the bolt 523 is closely combined with the wire 1, so that the wire 1 is connected with the contact 52 at one end of the fuse 5; Upper wire 1;

[0038] Step 2: After the fuse link 5 is connected to the wire 1, put the wire piercing sealing ring 4 on o...

Embodiment 2

[0044] Embodiment 2, a kind of fuse for two-wheel and three-wheel electric vehicle protection, such as Figure 10 , 11 , 12, 13, and 14, 1 is the connecting wire; 311 is the front protective seat cover; 711 is the rear protective seat cover; 401 is the wire perforated sealing ring; 51 is the fuse link; 61 is the protective seat cover interface sealing ring; 321 322 is the buckle; 323 is the seat post; 324 is the inner cavity of the protective cover; 325 is the perforation of the wire; 721 is the ferrule of the seat; 722 is the snap ring; 723 is the inner cavity of the protective cover; perforation.

[0045] The installation and use steps 1 are the same as those in Embodiment 1. Firstly, the wire 1 is put through the wire insertion hole 522 of the fuse body 5, and then the bolt is inserted into the wire fixing threaded hole 521, and the bolt is tightened down with a screwdriver or a torque wrench. , so that the lower end of the bolt is closely combined with the wire 1, so tha...

Abstract

The present invention relates to a fuse for protecting two-wheeled and three-wheeled electric vehicles. The fuse comprises a fuse body and a protective seat sleeve, a protective seat is provided witha fixed seat and has a waterproof function, and the fuse body is provided with a wire connecting hole. An insulator or a mounting base does not need to be additionally arranged on a circuit system, the fuse can be connected and installed on a line directly, and positioning columns and positioning grooves are arranged between the front and rear protective seat sleeves and in an inner cavity of theprotective seat sleeve, so that the axial dislocation between the front and rear protective seat sleeves and the axial rotation of the fuse body in the protective seat can be prevented. The fuse is more stable to combine, is novel in design, compact in structure, good in sealing performance and stability and reliable in circuit connection, is resistant to impact and vibration, and is a necessary safety protection device for the two-wheeled and three-wheeled electric vehicles. Meanwhile the fuse can be applied to the circuit safety protection systems of the small and low-speed electric vehicles, such as four-wheeled electric vehicles (elderly scooters), garden landscape vehicles, etc.

Description

Technical field: [0001] The invention relates to the protection field of two-wheel and three-wheel electric vehicles, and more specifically relates to a fuse used for protection of power storage batteries, charging systems and power circuit systems of two-wheel and three-wheel electric vehicles. Background technique [0002] With the trend of energy saving and emission reduction becoming more and more popular, urban road congestion is becoming more and more serious, and the demand of the masses is increasing. Two-wheel and three-wheel electric vehicles (electric bicycles, electric mopeds, electric motorcycles) are economical, energy-saving, The characteristics of vehicle emission and convenience are favored and developed rapidly. It has become the means of transportation chosen by more and more people. As of the end of June 2018, the number of two-wheel and three-wheel electric vehicles in China has reached 250 million. The number of three-wheeled electric vehicles and four-...
