Embodiment Construction

[0025] The multifunctional blade hub of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Such as Figure 1 to Figure 4 As shown, the multifunctional fan blade hub of the present invention includes: a hub body 1 and axial flow blades 2 arranged on the outer circumference of the hub body 1 . A plurality of centrifugal blades 3 evenly spaced are arranged on the inner wall of the hub body 1 circumference. The clamping groove 4 is clamped and fixed with the outer reinforcement ring 5 or directly integrally formed with the outer reinforcement ring 5 and the hub body 1 . The centrifugal blade 3 can dissipate heat to the armature winding (heating element), and at the same time dissipate heat to electrical components such as stator magnetic tiles, brushes, and inductors, and its shape adopts a curved leaf shape or a curved and swept combination shape, which can increase the air volume of the fan. Increase and redu...

Abstract

The invention provides a multifunctional fan blade hub. The multifunctional fan blade hub comprises a hub body and axial flow blades arranged on the outer circumferential surface of the hub body. The inner wall of the circumference of the hub body is provided with multiple centrifuge blades which are arranged evenly at intervals. The long edge of the axial side of each centrifuge blade is arranged on the inner wall of the circumference of the hub body. According to the multifunctional fan blade hub, the mode that an original hub is directly connected with a motor shaft through a single shaft is changed into the mode that the hub is directly connected with an armature through bosses, so that the connection stability is guaranteed, jumping between the hub and the armature is reduced, and the balancing performance is improved; when the multifunctional fan blade hub is applied to a matching fan, the ambient environment can be cooled, and a motor in the hub body can be effectively cooled through heat dissipation holes or cooling fins, so that the reliability of the fan is improved, and the service life of the fan is prolonged; the multifunctional fan blade hub is not provided with inserts and is integrally formed, so that the size precision of the blades is guaranteed more easily.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a heat dissipation component of an automobile, in particular to a multifunctional fan blade wheel hub. Background technique [0002] At present, most of the fan blades used in brushed DC motors have inserts. The fan blade hub is close to the front end cover of the motor. The central hole of the fan hub is passed by the shaft of the motor, and nuts or thrust pieces are required to connect the fan blade with the motor. When the motor is connected, it is necessary to ensure that the gap between the fan blade hole and the motor shaft is small enough. The nut of the general fan blade is easy to come off. If the fan blade hole and the shaft are tightly fitted, it is not conducive to disassembly and maintenance. In addition, the end cover is sandwiched between the hub of the fan blade and the armature, which makes it difficult for the motor to dissipate heat, and increases the axial d...
