Gear protrusion, stopper projection are arranged in the top of the body of rod, the central axis of the stopper projection of each kelly towards the pump housing.
Driving plate is along outer periphery along spaced set card slot, and the quantity of card slot and the quantity of kelly are identical, the shape of card slot
The shape size of the body of rod of shape and size and kelly matches.
Driving plate is located at the centre of kelly, and each card slot of driving plate is clamped with corresponding kelly, and driving plate is upper
Surface is located at the lower part of the lower section bevel edge of the stopper projection of kelly.
Kelly arranges surrounded circumference and pump housing coaxial line, kelly and pump housing integrated injection molding.
In the bottom at the close driving plate center of each card slot, a semicircular cavity has also been opened up respectively in two sides.
Groove width L1 of the width L2 of kelly slightly larger than the card slot of driving plate.
The utility model has the effect of positive: (1) the utility model is in fixed driving plate, on the internal chamber wall of the pump housing
The kelly that one circle along the circumferential direction equidistantly arranges, kelly and pump housing integrated injection molding are set；In driving plate, along periphery
Edge spaced set one encloses card slot, and the position that card slot is arranged is that the position without circuit is affirmed in driving plate, and the setting of card slot is not
Have the exposed problem of copper foil.
Each card slot of driving plate is corresponding to be clamped with each kelly, since the width of kelly is greater than the width of card slot,
Convenient for the pre-assembled of driving plate, and kelly and card slot are interference fitted, so that driving plate is fixed on pump body.Connect compared to screw
Mode is connect, snap fit assembly is simpler, also avoids the exposed problem of the possible copper foil of driving plate.
(2) on each kelly, it is additionally provided with one piece of stopper projection, the upper surface of driving plate is located at the lower section of stopper projection
(in terms of the orientation of Fig. 1), even if so that water pump strenuous vibration, there will not be the problem of driving plate is shifted or removed from kelly.

Specific embodiment
(embodiment 1)
See Fig. 1 to Fig. 4, in the fixed structure of the driving plate of the brushless electric water pump of the present embodiment, driving plate 3 by with
The mode that the 1 integrally formed kelly 2 in inside of the pump housing is clamped is fixedly connected on inside the pump housing 1.
Driving plate 3 is electrically connected with the stator winding of water pump, and the bottom of 1 inner cavity of the pump housing is arranged in driving plate 3.
See Fig. 2, kelly 2 has 3 or more (illustrating 4 in the present embodiment), 1 inner cavity of the pump housing bottom circumferentially to etc.
Spacing arrangement.Kelly 2 arranges surrounded circumference and 1 coaxial line of the pump housing.Kelly 2 and 1 integrated injection molding of the pump housing.
See that Fig. 3, the kelly 2 include the body of rod 21 and stopper projection 22, it is cuboid that the body of rod 21, which is strip,.Stop
The top that protrusion 22 is arranged in the body of rod 21, the central axis of the stopper projection 22 of each kelly 2 towards the pump housing 1.The present embodiment
In the section of stopper projection 22 be triangle, the other shapes such as stopper projection 22 or hemispherical.
See Fig. 4, the driving plate 3 is disc, encloses card slot 31, the number of card slot 31 along spaced set one along outer periphery
It measures identical as the quantity of kelly 2.The shapes and sizes of card slot 31 and the shape size of the body of rod 21 of kelly 2 match.Each
The bottom at 3 center of close driving plate of a card slot 31 has also opened up a semicircular cavity 32 in two sides respectively.
The width L2 of kelly 2 is slightly larger than the groove width L1 of the card slot 31 of driving plate 3, convenient for the pre-assembled of driving plate 3.
Kelly 2 is engineering plastic materials and parts, has certain deformation reset capability.
Driving plate 3 is placed on the centre of four kellies 2, and each card slot 31 of driving plate 3 is clamped with corresponding kelly 2, and
And the upper surface of driving plate 3 is located at the lower part of the lower section bevel edge of the stopper projection 22 of kelly 2.
See Fig. 5, after driving plate assembly, kelly 2 is in deformation state, at this time pressure of the driving plate 3 by kelly 2, pressure
Be divided into both direction: one is perpendicular to the downward pressure on 3 surface of driving plate, this power prevents driving plate from axially falling off；One flat
For row in the pressure of driving plate, this power prevents 3 radial displacement of driving plate.
In driving plate, card slot is enclosed along spaced set one along outer periphery, the position that card slot is arranged is agreed in driving plate
The fixed position without circuit, the setting of card slot do not have the exposed problem of copper foil.
In the fixed structure of the present embodiment, each card slot of driving plate is corresponding to be clamped with each kelly, is connected compared to screw
Mode is connect, snap fit assembly is simpler, also avoids the exposed problem of the possible copper foil of driving plate.On each kelly 2, also
Equipped with one piece of stopper projection 22, the upper surface of driving plate 3 is located at the lower section (in terms of the orientation of Fig. 1) of stopper projection 22, thus i.e.
Just water pump strenuous vibration there will not be the problem of driving plate is shifted or removed from kelly.
