Abstract
The utility model relates to a double-supporting ladder of an electric motor car. The utility model comprises two double-supporting clamping plates, a double-supporting leg, a double-supporting locking plate, two tension springs and a strengthening rib; a strip-shaped installation opening is dented and formed at the middle part of the front end at the upper part of the double-supporting clamping plate, and the upper and the lower edges of the outer edges of the installation opening respectively extending to form a positioning dummy club; the utility model further comprises two locking sheets respectively installed on the outer sides of the upper parts of the two double-supporting clamping plates, a strip-shaped installation opening is dented and formed at the middle part of one end of each locking sheet, and a rectangular positioning hole is formed at the other end. The double-supporting ladder of the electric motor car of the utility model can not only utilize the locking sheets to seal the front end of the installation opening, but also can utilize the matching of the positioning dummy club and the positioning hole to mutually fix the double-supporting clamping plate and the locking sheets, therefore not only the assembly is convenient, the operating efficiency is enhanced, but also the labor intensity of the operating personnel can be greatly reduced. In addition, the problem that the strength degradation of the double-supporting clamping plate caused by the installation opening changed from an installation slot opening is solved by adopting the locking sheets, therefore the overall structure is more stable.
Description
Technical field
The utility model relates to a kind of battery-driven car parts, particularly relates to two ladders of a kind of battery-driven car.
Background technology
When parking, battery-driven car utilize two ladders that are installed on its rear axle to support usually.Fig. 1 is two terraced forward structure scheme drawings of battery-driven car of prior art.Fig. 2 is two side of the ladder face structural representations of the battery-driven car shown in Fig. 1.Shown in Fig. 1～2, two ladders of the battery-driven car of this prior art mainly comprise two two cradle-splints 1, two supporting leg 2, two jam plates 3, two extension springs 4 and reinforced ribs 5; Wherein two two cradle-splints 1 are fixed on the main body both sides of battery-driven car by the installation slotted hole 6 that is positioned at its top and is used to run through the battery-driven car rear axle; Two supporting legs 2 are made of two side levers 7 and cross bar 8 one that are connected two side levers, 7 lower ends, and two upper end is hinged on the lateral surface bottom of two two cradle-splints 1 respectively; The upper end of two jam plates 3 is hinged on a side lever 7 outer upper of two supporting legs 2 by pivot shaft, therefore can left-right rotation; One end of each extension spring 4 is fixed on the outside of two cradle-splints 1, and the other end is separately fixed at a two side lever 7 outer lower portion of propping up jam plate 3 lateral surface bottoms and two supporting legs 2 that are positioned at the same side; The two ends of reinforced rib 5 are connected two side levers, 7 lower inside of two supporting legs 2, and the position, intermediate portion then is fixed on cross bar 8 middle parts of two supporting legs 2.But, there is following point in two ladders of the battery-driven car of this prior art: because the rear axle of battery-driven car is longer, and the installation slotted hole 6 that is used to run through on two cradle-splints 1 of rear axle is blind hole, two supporting legs 2 on two the ladders that operating personal needed to have assembled when two ladders therefore were installed direction to the left and right firmly separate, the two ends of rear axle are inserted in respectively in the installation slotted hole 6 on two cradle-splints 1, fix with nut locking at last.But owing to be fixed with reinforced rib 5 on two supporting leg 2, therefore be limited with regard to being difficult to two supporting legs 2 are divided right and left, labor intensity of operating personnel is increased, and work efficiency is lower.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of two ladders of battery-driven car that can alleviate labor intensity of operating personnel and high efficiency significantly.
In order to achieve the above object, two ladders of the battery-driven car that provides of the utility model comprise two two cradle-splints, two supporting leg, two jam plates, two extension springs and reinforced rib; Wherein two two cradle-splints are fixed on the main body both sides of battery-driven car; Two supporting legs are made of two side levers and the cross bar one that is connected two side lever lower ends, and two upper end is hinged on the lateral surface bottom of two two cradle-splints respectively; The upper end of two jam plates is hinged on a side lever outer upper of two supporting legs by pivot shaft, therefore can left-right rotation; One end of each extension spring is fixed on the outside of two cradle-splints, and the other end is separately fixed at the two side lever outer lower portion of propping up jam plate lateral surface bottoms and two supporting legs that are positioned at the same side; The two ends of reinforced rib are connected two side lever lower inside of two supporting legs, and the position, intermediate portion then is fixed on the cross bar middle part of two supporting legs;
The top front center of described pair of cradle-splint has been recessed to form a strip shape installing port, and lower edge is outwards outstanding respectively on the outer end of installing port is formed with a positioning boss; And two ladders of described battery-driven car also comprise two staies that are installed in two two cradle-splint upper outside respectively, and an end medial recess of each stay is formed with a strip shape opening, and the other end is formed with a rectangle knock hole.
The width of described stay upper shed equals the width of installing port on two cradle-splints.
The width of described rectangle knock hole is identical with the length of positioning boss, length then with two positioning boss lateral surfaces between distance equate.
Two ladders of the battery-driven car that the utility model provides are that the installation slotted hole that common double is propped up on terraced two cradle-splints is become the open strip shape installing port of front end, and outwards outstanding respectively positioning boss of lower edge on installing port, increased a stay that has strip shape opening and rectangle knock hole simultaneously, not only can utilize stay to close the front end of installing port like this, and the cooperation that can utilize positioning boss and knock hole fix with each other two cradle-splints and stay, therefore not only be convenient to assemble and increase work efficiency, and can alleviate labor intensity of operating personnel significantly.In addition, also can utilize stay to solve and make two cradle-splint strength degradation problems that the strip shape installing port causes into, thereby make the integral structure of two ladders more firm because of slotted hole is installed.
