The contact area of 20 junction of motor cabinet, its welded connecting area is big after welding, can improve down tube 10 and connect into motor cabinet 20
The bonding strength of junction after entirety, the connecting pin for avoiding down tube 10 in the prior art and motor cabinet 20 do not process direct weldering
Connect and cause bonding strength inadequate, in use easily junction lead to the problem of fatigue and be broken, improve it is electronic from
It drives a vehicle the service life of down tube and motor cabinet integrated member 100, the down tube 10 simultaneously because the two plug connection, at plug connection
Outer surface and 20 flush with outer surface of motor cabinet, so that junction appearance is smooth after integrally welded, it is beautiful, do not need the prior art
Since the junction of down tube and motor cabinet is not of uniform size, down tube is directly welded on the shell of motor cabinet, due to size after welding
It is different and lead to irregularity, while the weld filler of obvious protrusion needs multiple, many and diverse grinding-polishing to make junction close
Concordantly.The structure being welded to connect after grafting reduces the manpower and material resources of junction welding post-processing, and improves user to vehicle
The usage experience of frame integrated member 100.
It is appreciated that being welded to connect after the first connecting pin 11 and 21 grafting of second connection end, the first connecting pin 11 can be
It is plugged in second connection end 21, is also possible to second connection end 21 and is plugged in the first connecting pin 11.
Embodiment one, specifically, as shown in Fig. 2, the outer diameter of first connecting pin 11 is less than the outer diameter of 10 main body of down tube,
And first connecting pin 11 outer diameter be less than second connection end 21 internal diameter, the outer surface of first connecting pin 11 is plugged in second
The inner surface and welded connecting of connecting pin 21, the outer surface of the second connection end 21 and the appearance exposed at down tube plug connection
Face is concordant.I.e. the first connecting pin 11 of the present embodiment down tube 10 is less than the main part of down tube 10 and is plugged in the of motor cabinet 20
In two connecting pins 21 and welded.
Preferably, 11 length of the first connecting pin of the present embodiment is 1~5cm, corresponding 21 length of second connection end
For 1~5cm.To guarantee the bonding strength of down tube 10 Yu motor cabinet 20.
Further, as shown in figure 3, the outer surface of first connecting pin 11 of the present embodiment is provided with the first oblique angle 12, institute
It states 21 inner surface of second connection end and is also equipped with the second oblique angle 22 to match with the first oblique angle 12.First oblique angle 12 and second is oblique
The setting at angle 22 is convenient in the first connecting pin 11 swimmingly grafting and second connection end 21 and then being welded.
As shown in figure 4, the motor cabinet 20 of the present embodiment is provided with motor installation cavity 23 and motor fixing hole 24, the down tube
10 are provided with battery installing port 13 and battery installation cavity 14, and motor installation cavity 23 is connected to battery installation cavity 14.Motor is put into electricity
It is fixed in motor cabinet 20 after the motor installation cavity 23 of base 20 by motor fixing hole 24, battery is installed by the battery of down tube
Mouth 13 is put into battery installation cavity 14 and is fixed, and motor installation 23 is connected to wearing convenient for route with battery installation cavity 14.
Preferably, as shown in Figure 1, Figure 2 and Figure 4, the motor cabinet 20 of the present embodiment, which closes at second connection end 21, also opens up
There is charging socket mounting hole 25.Charging socket mounting hole 25 is for installing charging socket, the electric bicycle of this sample embodiment
Charging socket can be directly installed on by down tube and motor cabinet integrated member 100 when with the assembling of the other component of electric bicycle
Charging socket mounting hole 25 on motor cabinet 20, is not required to weld, also saves material.It is raw to overcome existing electric bicycle
In production technology, charging socket needs to make independent charging mounting, is then welded on the charging mounting for being equipped with charging socket
On vehicle frame, manufacturing process is troublesome and individually component materials expend big problem.
The Lower tube of electric bicycle and motor cabinet integrated member 100 that the utility model embodiment proposes, by down tube 10
First connecting pin 11 is set respectively at down tube 10 with the junction of motor cabinet 20, second connection end 21 is set in motor cabinet 20, the
It is welded to connect after one connecting pin 11 and 21 grafting of second connection end, and 10 outer surface of down tube of junction and 20 outer surface of motor cabinet
Concordantly, so that down tube 10 and the junction of motor cabinet 20 are smoothly beautiful, user experience is promoted.It is formed by welding after plug connection simultaneously
One overall structure is then welded to connect area increase, can improve the strong of junction since the junction contact area after grafting is bigger
Degree promotes the service life of down tube and motor cabinet integrated member 100.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model
