Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1 and Fig. 2, the utility model comprises first hanger branch 3 and the second hanger branch 6 of docking and being fastened and connected, both bottoms all offer the contour shape notch consistent with the contour shape of built-in motor 11 top, the space fallen into for built-in motor 11 top is formed between first hanger branch 3 and the bottom both the second hanger branch 6, plate body outside both the first hanger branch 3 and the second hanger branch 6 are positioned at offers the connecting bore of many group horizontal alignments, be equipped with binding bolt 8 often organizing in connecting bore, binding bolt 8 is by the first hanger branch 3, second hanger branch 6 is fixedly connected with as a whole with built-in motor 11 three.
Refer to Fig. 3 and Fig. 4, the outside face of plate body outside the first hanger branch 3 is positioned at, the position of each connecting bore are equipped with the nut pedestal of the nut 5 for accommodating binding bolt 8; The outside face of plate body outside the second hanger branch 6 is positioned at, the position of each connecting bore are equipped with the nut pedestal of the nut for accommodating binding bolt 8.In the present embodiment, the quantity of connecting bore is three groups, first group be opened in both the first hanger branch 3 and the second hanger branch 6 be positioned at outside plate body head end, other two groups be opened in both the first hanger branch 3 and the second hanger branch 6 be positioned at outside plate body middle part.Therefore nut pedestal has three, i.e. the first nut pedestal 1, second nut pedestal 9 and the 3rd nut pedestal 10, nut pedestal corresponding with it also has three, i.e. the first nut pedestal 2, second nut pedestal 4 and the 3rd nut pedestal 7.The nut of three binding bolts 8 falls in three nut pedestals respectively, nut falls in three nut pedestals respectively.
It is envisioned that the structure according to different built-in motor 11 and the different requirements to mounting process, the connecting bore of other group number can also be chosen, as set gradually four groups along hanger head end to the direction of tail end or five groups of binding bolts 8 are fixed installation.
Particularly, nut pedestal and nut pedestal can be chosen for following version: each nut pedestal and the first hanger branch 3 are formed in one structure, and each nut pedestal and the second hanger branch 6 are formed in one structure; The end face of nut pedestal is annular arrangement, and the end face of nut pedestal is water-drop-shaped; Nut 5 comprises band female sleeve 5-1 and one-body molded convex tongue 5-2 on sleeve 5-1 outer wall, that radially extend, and end face is water-drop-shaped.Like this, nut 5 embeds in the first nut pedestal 2, second nut pedestal 4 and the 3rd nut pedestal 7, laterally binding bolt 8 is penetrated by the connecting bore of the first nut pedestal 1, second nut pedestal 9 and the 3rd nut pedestal 10 three, the threaded portion of end screws in the sleeve 5-1 of nut 5, nut falls in each nut pedestal, the Liang Ge branch of hanger is fastenedly connected.By the advantage that each nut pedestal and nut 5 are designed to drop shape be: the aesthetic not only improving built-in motor 11 part, and effectively prevent the servo-actuated dismounting inconvenience problem brought of nut 5 in the process of unclamping and screw binding bolt 8.
In the present embodiment, both the first hanger branch 3 and the second hanger branch 6 are high strength aluminum alloy material, i.e. 6069 aluminum alloy materials.Each several part (comprising outer shape, connecting bore, each nut pedestal and each nut pedestal) is the integrated formed structure adopting same blank to obtain through forging and numerical control machining, adopts 3D FMT and CNC Computerized Numerical Control processing technology to forge and numerical control machining blank.
Fig. 5 is the using state structural representation of this hanger, can find out: the top of built-in motor 11 is clamped in the first hanger branch 3 and the second hanger branch 6 between the two, the profile of its both sides, top is consistent with the contour shape of Liang Ge hanger branch bottom notch, and laminating closely; Three laterally successively through the connecting bore on the connecting bore of the connecting bore in the second hanger branch 6, built-in motor 11 case top and the first hanger branch 3, is fixedly connected with after screwing by each binding bolt 8; Whole hanger is fixedly mounted on electric bicycle fame together with built-in motor 11.
