Abstract
The utility model discloses an electric bicycle frame, pipe and motor fixing base in down tube, frame five -way, frame, the internal surface of motor fixing base is fluted, and cooperate with shape and motor fixed muscle on the surface in the position of recess, radian that the surface profile that manages in the radian of the link of managing in motor fixing base and frame five -way and the frame and frame five -way and the frame suited. The frame of putting electric bicycle during this frame is compared has generally increased the frame five -way, each component parts's of frame of being convenient for location and equipment, and the motor fixing base has adopted newfashioned design, has saved the special positioning die when welding, has simplified frame manufacturing process, and the unnecessary screw fixation motor that uses when installing the motor in addition only utilizes the five -way can not rotate as locating hole and the protruding muscle of motor fixing base recess cooperation motor formation clearance fit, has simplified the process.
Description
Technical field
The utility model relates to a kind of cycle frame, is specifically related to a kind of electric bicycle fame.
Background technology
In the down tube of current electric bicycle fame, vehicle frame, each several part such as pipe is welded in motor fixing seat respectively, thus it is overall to form vehicle frame, relative position due to each parts requires fixing, therefore corresponding tooling fixture and jig be must use during welding, difficulty and the cost of production added.In addition, motor is generally connected with motor fixing seat by screw, and installation process is more time-consuming.
Utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model is to provide a kind of electric bicycle fame that need not use screw when not using special jig to complete motor fixing seat welding processing and mounted motor.
(2) technical scheme
For solving the problems of the technologies described above, there is provided a kind of electric bicycle fame, comprise pipe and motor fixing seat in down tube, frame five-through, vehicle frame, in vehicle frame, pipe is arranged on frame five-through, one end of motor fixing seat is managed with vehicle frame and frame five-through is connected, and the other end is connected with down tube.
Preferably, the inside face of described motor fixing seat is fluted, and the position of groove and shape match with the fixing muscle on motor surface.
Preferably, in motor fixing seat and frame five-through and vehicle frame, in the radian of the coupling end of pipe and frame five-through and vehicle frame, the surface configuration of pipe adapts.
(3) beneficial effect
Electric bicycle fame of the present utility model, compare general electric bicycle fame and add frame five-through, be convenient to location and the assembling of each component part of vehicle frame, motor fixing seat have employed new-type design, eliminate special jig during welding, simplify vehicle frame manufacturing process, need not screw be used during mounted motor in addition, only utilize five-way to form free-running fit as knock hole and motor fixing seat groove fit motor convex tendon can not rotate, simplify operation.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the electric bicycle fame according to the utility model embodiment.
Fig. 2 is the schematic diagram having installed the electric bicycle fame of motor and chain wheel according to the utility model embodiment.
Wherein, 1: down tube; 2: frame five-through; 3: pipe 4 in vehicle frame: motor fixing seat; 5: groove; 6: motor; 7: fixing muscle.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Fig. 1 is the schematic diagram of the electric bicycle fame according to the utility model embodiment.Fig. 2 is the schematic diagram having installed the electric bicycle fame of motor and chain wheel according to the utility model embodiment.This electric bicycle fame comprises pipe 3 and motor fixing seat 4 in down tube 1, frame five-through 2, vehicle frame, and in vehicle frame, pipe 3 is arranged on frame five-through 2, and one end of motor fixing seat 4 is connected with pipe in vehicle frame 3 and frame five-through 2, and the other end is connected with down tube 1.Motor axis is arranged in frame five-through 2, the base portion of motor 6 is in motor fixing seat 4, the fixing muscle 7 on motor 6 surface snaps in the groove 5 of motor fixing seat 4 inside face, and the position of groove 5 and shape match with fixing muscle 7, and motor 6 can not be got loose from motor fixing seat 4.In the radian of motor fixing seat 4 and the coupling end of pipe 3 in frame five-through 2 and vehicle frame and frame five-through 2 and vehicle frame, the surface configuration of pipe 3 adapts, directly motor fixing seat 4 and the correspondence position of pipe 3 in frame five-through 2 and vehicle frame are fitted when welding, special jig need not be used to assist, motor fixing seat 4 relies on the circular arc of frame five-through 2 as vertical reference simultaneously, ensures that motor fixing seat 4 is positioned at vehicle frame center.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
