Abstract
The utility model discloses a hold-down mechanism for a battery module of an electric vehicle. The hold-down mechanism comprises an inverted L-shaped fixing base, wherein a plurality of columnar tracks are horizontally arranged on the inside wall of the fixing base, a slide block is in sliding fit with the columnar tracks through internal sleeves, and check rings are clamped on the columnar tracks on the outer sides of the sleeves; a wedge-shaped pressing block arranged between the slide block and the inside wall of the fixing base is in contact with an inclined plane above the slide block; and a guiding nut is arranged on the top plate of the fixing base, an upper screw rod of a bolt bearing on the wedge-shaped pressing block penetrates out of the guiding nut, and a butterfly compression nut is screwed on the upper screw rod. The hold-down mechanism provided by the utility model has the advantages of simple structure, and capability of greatly improving the installation and disassembly efficiencies of the battery module.
Description
Technical field
The utility model relates to the battery for electric automobile module, especially relates to a kind of batteries of electric automobile module and uses hold-down mechanism.
Background technology
Electric automobile has obtained fast development with the advantage of its energy-conserving and environment-protective.But because the energy density of vehicle mounted dynamic battery is still not ideal enough, the continual mileage of electric automobile single charge is shorter, and the time of the each charging of battery is oversize, make electric automobile use and popularization is restricted.In order to solve the short problem of battery continual mileage, the fast changing battery mode has obtained primary study, and the layout and the fixed form of battery module then are the key points in the quick change mode in the Battery case.
Summary of the invention
The utility model purpose is to provide a kind of and had not only made things convenient for battery module to change fast, but also can limit battery module movable batteries of electric automobile module in Battery case use hold-down mechanism.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described batteries of electric automobile module of the utility model is used hold-down mechanism; It comprises down the fixed pedestal of L shaped structure; Many column tracks on the madial wall of said fixed pedestal, have been horizontally disposed with; Sliding shoe is slidingly matched through sleeve inside and said column track, on the column track in the sleeve outside, is installed with back-up ring; The wedge shape briquetting that between sliding shoe and fixed pedestal madial wall, is provided with contacts with the inclined-plane above the sliding shoe; The top board of said fixed pedestal is provided with spigot nut, places the upper screw of the bolt bearing on the wedge shape briquetting to pass from the nut that leads, and has screwed the butterfly clamping nut on it.
The utility model advantage is simple in structure, can improve installation, the removal efficiency of battery module greatly.The last lower baffle plate of Battery case has limited the motion of battery module in the Z direction; The column guide rail has limited the motion of battery module at directions X; Hold wedge shape briquetting that is pressed on the sliding shoe and the back-up ring that is installed on the column track of the sleeve outside through bolt shaft and limited the motion of battery module in the Y direction; Whole hold-down mechanism had both guaranteed the battery module fixation, made things convenient for the quick dismounting and change of battery module again.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the decomposing schematic representation of the utility model.
Embodiment
As shown in the figure; The described batteries of electric automobile module of the utility model is used hold-down mechanism; It comprises down the fixed pedestal 1 of L shaped structure; On the madial wall of fixed pedestal 1, be horizontally disposed with many column tracks 2, sliding shoe 3 is slidingly matched through sleeve inside 4 and column track 2, on the column track 2 in sleeve 4 outsides, is installed with back-up ring 5; The wedge shape briquetting 6 that between sliding shoe 3 and fixed pedestal 1 madial wall, is provided with contacts with the inclined-plane above the sliding shoe 3; The top board of fixed pedestal 1 is provided with spigot nut 7, places the upper screw 9 of the bolt bearing 8 on the wedge shape briquetting 6 to pass from the nut 7 that leads, and has screwed butterfly clamping nut 10 on it.
The utility model has limited the motion of battery module in the Y direction through the wedge shape briquetting 6 that bolt bearing 8 is pressed on the sliding shoe 3 with the back-up ring 5 that is installed on the sleeve outside column track 2; The guide rail of battery module has limited its motion at directions X in the Battery case, and the last lower baffle plate of Battery case has limited the motion of battery module in the Z direction.Promptly screw butterfly clamping nut 10; The column track 2 of sliding shoe 3 fixed pedestal 1 in the suppressing action lower edge of wedge shape briquetting 6 is done directed the slip; And preventing that through E shape back-up ring 5 it breaks away from column track 2, the limit battery module makes battery module be able to fix in the motion of Y direction; Screw butterfly clamping nut 10 in the other direction, just can in Battery case, take out this hold-down mechanism, the battery module that more renews is dismantled, installs very convenient, rapid.
