Abstract
The utility model belongs to an electric vehicle with a novel vehicle ladder connection structure, which comprises a vehicle frame, a vehicle seat, a vehicle wheel and a vehicle ladder, wherein two bracing frames on the rear end of the vehicle frame are equipped with rear vehicle shafts and the vehicle ladder, and connecting pieces are extended and fixed on the rear end portions of the two bracing frames on the rear end of the vehicle frame , and the connecting pieces are mounted on the rear vehicle shafts through plug-in grooves which are arranged on the connecting pieces, and the vehicle ladder is mounted on the connecting pieces. The utility model has the advantages of simple structure, novel design and strong practicability, which can lower the production cost. The electric vehicle with a novel vehicle ladder connection structure can not cut electrical wires which are threaded on a main shaft in the process of assembling, which does not need to disassemble the vehicle ladder when a rear vehicle wheel of the electric vehicle is repaired, thereby improving the stability when the electric vehicle is repaired, lowering the difficulty of repairing, and guaranteeing the flexible and free rotation when the vehicle ladder is used.
Description
Technical field
The utility model belongs to electric automobiles, especially a kind of battery-driven car with new car ladder connection structure.
Background technology
Battery-driven car is that a kind of manpower of realizing is ridden and electronic extraordinary bicycle of riding.Therefore battery-driven car owing to have flexible, comfortable laborsaving, the advantage such as speed is fast and energy consumption is little of riding enjoys numerous bicyclists' favor and welcome.A connecting strap is all installed by the riveted joint mode in the upper end of electric bicycle ladder support both sides at present, all be shaped on inserting slit on these two connecting straps and be inserted into by this inserting slit on the main shaft of battery-driven car rear wheel, and these two connecting straps respectively are fixed on the back axle by an adapter plate.Find that in long-term production and use existing car ladder connection structure exists following defective: 1. be coated with electric wire on the battery-driven car back axle, because connecting strap cooperates tightr with installation between the back axle, therefore not only cause the car ladder that difficulty is installed, and in the installation process of car ladder, also scratch electric wire easily, cause battery-driven car to damage; 2. because car is terraced and back axle is installed together, therefore when being keeped in repair, the battery-driven car rear wheel car ladder need be unloaded, causing battery-driven car to lose the strong point can not stand, and existing battery-driven car heaviness, weight are big, a plurality of electric components such as motor, control capsule also are installed on the vehicle frame, it can not be flipped upside down when causing keeping in repair, thereby make troubles to maintenance work; 3. the electric bicycle ladder adopts riveted way to install with connecting strap, its riveted joint dynamics between the two is wayward when production and assembly, the fastness of installing between dynamics too small then car ladder and the connecting strap is poor, and the excessive then connecting strap of dynamics can not freely rotate, thereby increased the difficulty of making is installed.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of battery-driven car with new car ladder connection structure easy to manufacture, easy to assembly is provided.This battery-driven car has can not hurt practical characteristics easy for installation between the electric wire on the back axle, convenience easy to maintenance and car ladder and the connecting strap in the installation process of car ladder.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of battery-driven car with new car ladder connection structure, constitute by vehicle frame, vehicle seat, wheel and car ladder, two bracing frames of vehicle frame rear end are installed back axle and car ladder, it is characterized in that: the rearward end extension of two bracing frames of vehicle frame rear end is fixed with connecting strap, connecting strap is installed on the back axle by inserting slit made on it, and the car ladder is installed on connecting strap.
And the upper end, support both sides of described car ladder all is shaped on the clamping plate that an opening makes progress, the lower end of this clamping plate setting-in connecting strap.
And described clamping plate are installed on the connecting strap by a screw, and endwisely slip between this screw and the connecting strap and be set with a sliding sleeve, and screw and sliding sleeve install by screw thread.
And, install a locating dowel pin that can mount car ladder upper spring on the described connecting strap.
Advantage of the present utility model and beneficial effect are:
1. the extension of the rearward end of two of this electromobile frame rear end bracing frames is fixed with connecting strap, and connecting strap is installed on the back axle by inserting slit made on it, and the car ladder is installed on connecting strap.Because integrative-structure is made in the welding of connecting strap and bracing frame, and its lower end hinge is contained in the clamping plate of car ladder, so installs simple and conveniently, and can not hurt the electric wire that installs on the back axle in assembling process.
2. because connecting strap and bracing frame are made integrative-structure, and the car ladder is installed on the connecting strap, so when the battery-driven car rear wheel is keeped in repair, will not pull down by the car ladder, thereby the degree of stability when having improved the battery-driven car maintenance has reduced the difficulty of keeping in repair, and has shortened maintenance time.
3. connecting strap is contained in the clamping plate of car ladder upper end by the screw hinge, and is set with sliding sleeve between this screw and the connecting strap, has replaced original riveted joint mode.This mounting means is simple and convenient, has both had advantage lower to accuracy requirement, that be easy to apply, has guaranteed the alerting ability that the car ladder rotates again.
4. the utility model is simple in structure, novel in design, practical and can reduce production costs.This battery-driven car has in assembling process can not hurt the electric wire that installs on the main shaft; When the battery-driven car rear wheel is keeped in repair, will not pull down by the car ladder, thereby the degree of stability when improving the battery-driven car maintenance reduces the advantage of maintenance difficulty; And it is free flexibly to guarantee that the car ladder rotates when using.

The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
Originally have the battery-driven car of new car ladder connection structure, constitute by vehicle frame 1, vehicle seat 2, wheel 6 and car ladder 8.Two bracing frames 3 of vehicle frame rear end are installed back axle 14 and car ladder.Innovative point of the present utility model is: the rearward end of two bracing frames of vehicle frame rear end is all extended welding and is fixed with connecting strap 4, and these two connecting straps were installed on the back axle by inserting slit made on it 9 and cooperating of nut 5, and the car ladder is installed on connecting strap.
The upper end, support 7 both sides of this electric bicycle ladder all is shaped on the clamping plate 12 that an opening makes progress, the lower end of this clamping plate setting-in connecting strap.Its concrete hinge assembling structure is: clamping plate are installed on the connecting strap by a screw 11, and endwisely slip between this screw and the connecting strap and be set with a sliding sleeve 15, and screw and sliding sleeve install by screw thread, so the car ladder can be realized freely rotating.Install a locating dowel pin 10 that can mount car ladder upper spring 13 on the connecting strap.
