Description
Technical Field
The utility model relates to an electric bicycle field especially relates to an electric bicycle stator connection structure.
Background
The electric bicycle is widely used as a mass travel tool, the number of electric bicycles manufactured by manufacturers every year is considerable, the motor is very important as an essential power component of the electric bicycle, and the performance of the electric bicycle is directly influenced by the quality of the motor;
when manufacturing the motor, one of them process is just as an organic whole with axle and stator assembly, and traditional process is connected through the key realization between axle and the stator to reach the purpose of circumference location, but such process just needs the manual work to strike the key, has lengthened production cycle, has also increased the recruitment cost of enterprise simultaneously.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing an electric bicycle stator connecting structure.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an electric bicycle stator connection structure, includes stator core and axle, the centre bore has been seted up in the middle of the stator core, the stator core nestification is installed in the periphery of axle, and the pore wall of centre bore is equipped with a protruding muscle at least, is equipped with the recess on the axis body lateral wall of axle, and when stator core installs epaxially, protruding muscle clamps and realizes circumferential positioning in the recess.
Preferably, stator core and axle are integrated into one piece casting shaping, and the axis body of axle has with stator core matched with assembly section, and the recess is located the lateral wall of assembly section, and the recess extends to the other end from the one end of assembly section, and the one end of assembly section still is equipped with stator core matched with annular step, and when stator core installed epaxially, stator core supported and leaned on annular step.
Preferably, the annular step is further provided with a notch matched with the convex rib.
Preferably, both ends of the assembling section are respectively provided with a first annular assembling groove and a second annular assembling groove, and the second annular assembling groove is positioned at the annular step.
Preferably, the stator core is located at the periphery of the central hole and is provided with three casting holes which are uniformly arranged along the circumferential direction.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses the key need not be used in the assembly of stator core and axle, but clamps through protruding muscle and realize the circumference location in the recess, so not only reduced the quantity of motor spare part, also need not the workman to carry out the action of manual strike key simultaneously, the manufacturing time has been practiced thrift, the recruitment cost of enterprise has also been reduced simultaneously, and further, because stator core and axle all are integrated into one piece, consequently increase a protruding muscle on stator core and can not increase too much cost of enterprise and manufacturing time yet.

Fig. 1 is a schematic view of a structural relationship between a stator core 1 and a shaft 2 according to the present invention;
fig. 2 is a schematic perspective view of the present invention;
fig. 3 is a schematic structural diagram of the assembly section 6 of the present invention.
In the figure: 1 stator core, 2 axles, 3 centre holes, 4 convex ribs, 5 grooves, 6 assembling segments, 7 annular steps, 8 gaps, 9 annular assembling grooves, 10 casting holes and 11 second annular assembling grooves.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, an electric bicycle stator connection structure, includes stator core 1 and axle 2, stator core 1 is middle to be seted up centre bore 3, stator core 1 nestedly installs in the periphery of axle 2, and the pore wall of centre bore 3 is equipped with a protruding muscle 4 at least, is equipped with recess 5 on the axis body lateral wall of axle 2, and when stator core 1 installed on axle 2, protruding muscle 4 clamps and realizes circumferential positioning in recess 5.
Preferably, stator core 1 and axle 2 are integrated into one piece casting shaping, and the axis body of axle 2 has and stator core 1 matched with assembly section 6, and recess 5 is located assembly section 6's lateral wall, and recess 5 extends to the other end from assembly section 6's one end, and assembly section 6's one end still is equipped with stator core 1 matched with annular step 7, and when stator core 1 installed on axle 2, stator core 1 supported and leans on annular step 7.
Preferably, the annular step 7 is further provided with a notch 8 matched with the convex rib 4. When stator core 1 supports and leans on annular step 7 like this, protruding muscle 4 can get into breach 8, realizes better spacing purpose.
Preferably, both ends of the fitting segment 6 are respectively provided with a first annular fitting groove 9 and a second annular fitting groove 11, and the second annular fitting groove 11 is located at the annular step 7. Clamp springs can be clamped and fixed in the first annular assembling groove 9 and the second annular assembling groove 11, so that the front end and the rear end of the stator core 1 can be further fixed through the two clamp springs.
Preferably, the stator core 1 is located at the periphery of the central hole 3 and has three casting holes 10 uniformly arranged in the circumferential direction.
It should be noted that the utility model discloses the standard part that uses all can purchase from the market, and dysmorphism piece can all be customized according to the record of description and attached drawing, and the concrete connected mode of each part all adopts conventional means such as mature bolt, rivet, welding among the prior art, and machinery, part and equipment all adopt among the prior art, conventional model, and the inventor does not detailed herein again.
