The aerofoil fan being connected in series with and electric product of the embodiment of the present invention are illustrated below in conjunction with the accompanying drawings.
Embodiment 1
The present embodiment 1 provides a kind of motor.Fig. 1 is that the aerofoil fan being connected in series with of the embodiment of the present invention 1 is when assembled
Structure diagram.As shown in Figure 1, the frame of aerofoil fan 10 being connected in series with is combined by the first casing 11 and the second casing 12
It forms, the first casing 11 has multiple first through holes 111, is located at the first end 112 of 12 side of the second casing (in Fig. 1
Right end), the second casing 12 has multiple second through holes 121, is located at the second end 122 of 11 side of the first casing (in Fig. 1
Left end), the first through hole 111 and the second through hole 121 are in direction (Fig. 1 of 12 arranged in series of the first casing 11 and the second casing
In OO ' axis directions) on overlap each other, the first through hole 111 is connect with the second through hole 121 by connecting pin 13.
In this way, the first casing 11 and the second casing 12 of the aerofoil fan 10 are connected by connecting pin 13, it can be by two
Strong case it is fixed also, different from the connecting components such as screw, due to being only inserted into pin, there is preferable workability.
In the present embodiment, multiple connecting pins 13 can be set in the aerofoil fan 10 being connected in series with, for example, in the first machine
Connecting pin 13 is set respectively on the quadrangle of shell and the second casing, i.e., 4 connecting pins are set altogether.
Fig. 2 is the structure diagram of the connecting pin of the embodiment of the present invention 1.As shown in Fig. 2, connecting pin 13 has：First card
11 side of the first casing is fixed in conjunction portion 131；And second holding section 132, it is fixed on 12 side of the second casing, first
The outer diameter of 131 and second holding section 132 of holding section is bigger than the first through hole 111 and the second through hole 121.
In this way, since there is holding section 131,132 at the both ends of connecting pin 13, can anti-shotpin come off, also, logical
It crosses holding section 131,132 to contact and fix with first end 112 and the second end 122 respectively, therefore can further securely
Two casings are fixed on ground.
In the present embodiment, the first holding section 131 or the second holding section 132 have rake 133, direction and first
End 112 or the opposite direction of the second end 122 make reduced diameter.For example, as shown in Fig. 2, the second holding section 132 have incline
Inclined portion 133 makes reduced diameter towards the direction opposite with first end 112.In this way, by using rake 133, Neng Gourong
It changes places and is inserted into the casing of side.
In the present embodiment, as depicted in figs. 1 and 2, the end of rake 133 have the plane of disruption 134, connecting pin 13 for
The part stage has the guide part 135 of long axis, in order to play the role of guiding in assembling.In this way, by setting the plane of disruption
134, guide part 135 can be cut off after finishing assembly.
Fig. 3 is the structure diagram after the aerofoil fan being connected in series with of the embodiment of the present invention 1 is completed.Such as Fig. 3 institutes
Show, after aerofoil fan 10 is completed, cut off guide part, complete assembling.
In the present embodiment, connecting pin 13 can be silicon class rubber connecting pin, shaking during so as to reduce fan running
It is dynamic.
In the present embodiment, first end 112 or the second end 122 be in the direction orthogonal with the direction of arranged in series,
With the groove portion (not shown) by the first through hole 111 or the second through hole 121.In such manner, it is possible to it is inserted into from side side
Connecting pin.
In addition, the width of the groove portion can be smaller than the internal diameter of the first through hole 111 or the second through hole 121, such energy
Enough prevent connecting pin from coming off from side side.
Fig. 4 is the first casing of the embodiment of the present invention 1 and the exploded view of the second casing.As shown in figure 4, in first end
112 setting first axis snap fasteners 113 and the first engaging unlocking mechanism 114 are set and first axis in the second end 122
The the second axial snap fastener 123 and the second engaging for engaging the pairing of unlocking mechanism 114 with first that snap fastener 113 matches
Unlocking mechanism 124, the axial snap fastener 123 of first axis snap fastener 113 and second can be prevented to aerofoil fan 10
The movement of axial OO ', the first engaging unlocking mechanism 114 and second engage unlocking mechanism 124 by the first casing 11 and second
Casing 12 along defined direction relatively reverse when, by torsion more than specified value, the first casing 11 and can be unlocked
The fastening state of two casings 12, when first end 112 is abutted with the second end 122, first axis snap fastener 113 and second
Axial snap fastener 123 engages with each other.
In the present embodiment, which is, for example, direction (OO ' the axis side in Fig. 4 with 12 arranged in series of casing
To) vertical circumferential direction, which can be set according to the material and actual conditions of casing 12.
In this way, by setting snap fastener, two casings can be further firmly fixed.
In the present embodiment, for example, as shown in figure 4, first axis snap fastener 113 is formed as convex in first end 112
Shape portion 1131, the second axial snap fastener 123 are formed as concavity 1231 in the second end 122.In this way, due to snap fastener shape
As concaveconvex shape, therefore it can further firmly fix two casings.
In the present embodiment, for example, the convex shaped part 1131 can flexible deformation, in this way, engaged by flexible deformation, because
This can prevent the damage of the snap fastener of casing.
In the present embodiment, for example, the aerofoil fan 10 being connected in series with is the first aerofoil fan and the second aerofoil fan company
The fan being connected together, the first aerofoil fan have the first impeller (not shown) and the first casing 11, the second aerofoil fan tool
There are the second impeller (not shown) and the second casing 12.Wherein, the direction of rotation of the first impeller and the direction of rotation of the second impeller
Can be opposite.
It, can will by above-described embodiment it is found that the first casing and the second casing by connecting the pin connection aerofoil fan
Two strong cases it is fixed also, different from the connecting components such as screw, due to being only inserted into pin, there is preferable work
Industry.
