In order to solve the problem, the utility model aims to provide a radiator fan assembly that reasonable in design is reliable mainly optimizes the fan blade structure for the equilibrium of fan blade is better.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an auto radiator fan assembly, includes fan frame, motor and fan blade, the mount pad of power supply machine installation in the fan frame, the motor is fixed on this mount pad, the fan blade with the rotor position of motor is connected, the fan blade is established the lid at motor rotor position including the lid, and it has the blade of circumference equipartition to distribute on the lid periphery wall, the structure of lid includes the ring body, is equipped with annular cover body in the axis position of this ring body, link to each other through the connection piece of circumference equipartition between the inner wall of cover body and ring body, the connection piece be "Y" shape connect into an organic whole through the ring piece between the connection piece.
The connecting piece is characterized in that one end of the connecting piece is provided with a forked opening, the other end of the connecting piece is provided with a straight strip part, the forked opening is connected to the inner wall of the annular body, the straight strip part is connected to the sleeve body, the inner wall of the annular body is provided with blocking pieces which are uniformly distributed on the circumference, and the blocking pieces are arranged in the forked opening.
The blocking sheet is provided with a cutting groove.
The interval between the connecting sheets forms a heat dissipation hole.
The utility model discloses a back is laid to this kind of structure, the form that the lid bottom on the blade passes through the connection piece, can effectively reduce expend with heat and contract with cold's influence for connection piece thickness after injection moulding can keep the uniformity, improves the radiating effect of motor simultaneously, makes the structure more reasonable, and this fan blade assembly back on the motor can realize better ride comfort, the vibration and the noise of the fan blade that have significantly reduced.
The invention is further described with reference to the accompanying drawings and the detailed description.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The present invention is described in detail below with reference to the following examples, which are only used for further illustration of the present invention, and should not be construed as limiting the scope of the present invention.
As shown in fig. 1, the embodiment discloses a fan assembly of a radiator for an automobile, which comprises a fan frame 1, a motor and a fan blade 2, a mounting seat for mounting the motor is arranged in the fan frame 1, the motor is fixed on the mounting seat, the fan blade 2 is connected with a rotor part of the motor, the fan blade 2 comprises a cover body 21 covering the rotor part of the motor, blades 22 are distributed on the outer circumferential wall of the cover body 21, the cover body 21 structurally comprises an annular body 210, an annular sleeve body 211 is arranged on the central axis of the annular body 210, the sleeve body 211 is screwed with a motor rotating shaft through a nut after the motor rotating shaft is inserted, so as to lock and fix the fan blade 2, the sleeve body 211 is connected with the inner wall of the annular body 210 through connecting pieces 212 which are uniformly distributed on the circumference, the connecting pieces 212 are in a Y shape, the connecting pieces 212 are integrally connected by a plurality of circular ring pieces 213, and the center line of the circular ring pieces 213 is consistent with that of the sleeve body 211.
The Y-shaped connecting piece 212 has a branched opening 2121 at one end and a straight portion 2122 at the other end, the branched opening 2121 is connected to the inner wall of the ring body 210, the straight portion 2122 is connected to the sleeve body 211, the inner wall of the ring body 210 is provided with circumferentially and uniformly distributed blocking pieces 213, and the blocking pieces 213 are disposed in the branched opening 2121. The structure can make the contact area of the bottom surface larger, so that the cover body 21 and the rotating part of the motor are more tightly sleeved and matched.
The thickness of the stopper 213 is the same as that of the coupling piece 212, and the stopper 213 is provided with a slit which also prevents a change in thickness due to expansion and contraction with heat and injection pressure.
The spaces between the connecting pieces 212 form heat dissipation holes 3. The structure can lead the heat of the motor to be taken away by the fan blade through the heat dissipation holes 3 more quickly, thereby protecting the components in the motor.
Adopt above-mentioned technical scheme, the back is laid through the form of connection piece 212 in lid 21 bottom on the blade 22, can effectively reduce expend with heat and contract with cold's influence for connection piece 212 thickness after the injection moulding can keep the uniformity, improves the radiating effect of motor simultaneously, makes the structure more reasonable, and this fan blade 2 assembly back on the motor can realize better ride comfort, the greatly reduced vibration and the noise of fan blade 2.
