Description
Technical field
The utility model is relevant with electric booster bicycle, espespecially a kind of motor support assembly of electric booster bicycle.
Background technology
In order to avoid the motor of electric booster bicycle interferes with each other when mounted and between other components (as wheel, large fluted disc, chain or change-speed box), motor is normally fixed on vehicle frame by bracket by current design, to reach the object of installing smoothly.
With regard to relevant prior art, motor and bracket are locked together by many bolts after being bottom surface motor being resisted against bracket by Japanese Patent No. 3697965 Patent Case again, but, the mounting means of this existing Patent Case has no idea to allow motor and bracket closely combine, motor is caused easily to have the situation of rocking, in addition, the junction between motor and bracket is easy to the concentrated phenomenon of stress occurs, and just can cause the structural failure of bracket or shell under permanent use.Therefore, aforementioned existing Patent Case structurally has necessity of improvement.
Utility model content
Main purpose of the present utility model is the motor support assembly providing a kind of electric booster bicycle, and it to promote between motor and bracket structural soundness after assembling.
In order to reach above-mentioned purpose, motor support assembly of the present utility model includes a bracket and a driver element.This bracket has a board and a support tube, and this support tube is connected to the bottom surface of this board; This driver element has a shell and a motor, this shell is located at the board of this bracket and is had the axis hole of a crank central siphon this crank central siphon relative to, this crank central siphon is arranged in the support tube of this bracket from one end of the support tube of this bracket, this axis hole is communicated in the other end of the support tube of this bracket, and this motor to be located in this shell and to be positioned at the inside of the board of this bracket.
Wherein this shell has one first side cover and one second side cover, be bonded with each other between this first, second side cover and be positioned at the two relative side of this bracket, this first side cover has this crank central siphon, and this second side cover has this axis hole, and this motor is located between this first, second side cover.
Wherein this bracket has at least two floors, and this two floor is connected between the bottom surface of this board and this support tube.
Wherein this shell is locked in this board.
Wherein this driver element outer peripheral edges by this board local envelope.
Wherein the outer peripheral edges of this driver element are enveloped completely by this board.
The beneficial effects of the utility model are, it to promote between motor and bracket structural soundness after assembling.
Accompanying drawing explanation
For further illustrating technology contents of the present utility model, be described in detail as follows below in conjunction with embodiment and accompanying drawing, wherein:
Fig. 1 is the three-dimensional combination figure of the utility model the 1st embodiment.
Fig. 2 is the three-dimensional exploded view of the utility model the 1st embodiment.
Fig. 3 is the three-dimensional exploded view of the utility model the 2nd embodiment.
Fig. 4 is the three-dimensional exploded view of the utility model the 2nd embodiment.
Detailed description of the invention
Please first consult Fig. 1 and Fig. 2, the motor support assembly 10 of the utility model the 1st embodiment includes bracket 20 and a driver element 30.
Bracket 20 has board 21 and a support tube 22.The end face of board 21 from front to back respectively with one before pipe 12, pipe 14, and a back breeches pipe 16 connects, and support tube 22 is connected to the bottom surface of board 21 at the present embodiment by trislab 23.
Driver element 30 has a shell 31, shell 31 has one first side cover 32 and one second side cover 33, first, second side cover 32, be joined to each other between 33 and with locking or other fixed forms be assembled in bracket 20 two opposite sides, make driver element 30 can by the board 21 of bracket 20 local envelope, in addition, a crank central siphon 34 is extended towards the direction of bracket 20 in the rear end of the first side cover 32, one end of crank central siphon 34 self-supporting pipe 22 is arranged in support tube 22, the rear end of the second side cover 33 has an axis hole 35, axis hole 35 is communicated in the other end of support tube 22, a crank shaft (not shown) can be allowed thus to be arranged in crank central siphon 34 via axis hole 35.Driver element 30 has more a motor 36, motor 36 is installed between the front end of first, second side cover 32,33 of shell 31, make motor 36 be positioned at after mounting the board 21 of bracket 20 bottom surface and by first, second side cover 32,33 of shell 31 local envelope.Thus, motor 36 can provide power-assisted to the crank shaft be located in crank central siphon 34, rotates with driving crank axle.
From said structure, motor support assembly 10 of the present utility model mainly arranges support tube 22 in the below of bracket 20 allows the crank central siphon 34 of shell 31 wear, again motor 36 is arranged in shell 31, under compared with the design so with existing Patent Case, motor being directly locked in bracket, the utility model can allow motor 36 more stably be fixed together with bracket 20, increases structural stability to reach and reduces the concentrated object of stress.
It should be added that at this, structure of the present utility model can have different change, as shown in Figure 3, the support tube 42 of bracket 40 can be connected to the bottom surface of the board 41 of bracket 40 by an extension pipe 43, extension pipe 43 passes board 41 by the bottom of seat pipe 14 formed, and can reach effect board 41 and support tube 42 are fixed together so equally.Again as shown in Figure 4; the board 51 of bracket 50 can be designed to be surrounded on the outer peripheral edges of driver element 30 and envelope whole for the outer peripheral edges of driver element 30; except structural stability after finishing assembly can be increased between driver element 30, the protected effect to driver element 30 can be increased again simultaneously.
