Abstract
The utility model discloses a breather valve structure of a brushless motor controller for an automobile cooling fan, which comprises a motor base and is characterized in that a breather hole is arranged on the motor base, and the breather hole is L-shaped; a waterproof and breathable film is pasted on an orifice of one side of the motor base, which is used for the controller, close to the breathing hole. The utility model discloses a direct gum of ventilated membrane to paste on the internal surface of motor base installation controller one side, through the L type breather hole on the motor base, play waterproof ventilative effect, external muddy water simultaneously, dust, gravel and sand also can not direct action on waterproof ventilated membrane, ensure that product life and durability are better. The position that the breather was seted up is as the gas tightness inspection hole after motor base and controller and the motor end cover assembly, accomplishes dual-purpose.
Description
Technical Field
The utility model relates to an automobile cooling fan technical field, in particular to automobile cooling fan is with brushless motor controller breather valve structure.
Background
The existing breather valve structure of the brushless motor controller for the automobile cooling fan occupies a large space, is complex in structure, increases the possibility of failure, and is low in waterproof grade and high in cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that it is big to be used for brushless motor controller breather valve structure occupation space for automobile cooling fan to current, and the structure is complicated, and trouble possibility increases, and waterproof grade is lower, and problem such as with high costs and provide a brushless motor controller breather valve structure for automobile cooling fan that occupation space is little, simple structure, trouble possibility reduces, waterproof grade is higher, with low costs.
The utility model discloses the technical problem that will solve can realize through following technical scheme:
a brushless motor controller breather valve structure for an automobile cooling fan comprises a motor base, wherein a breather hole is formed in the motor base, and a waterproof breathable film is pasted on an orifice of one side, close to the motor base, of the breather hole, and used for a controller; the breathing hole is L-shaped.
In a preferred embodiment of the present invention, an end orifice of the breathing hole communicating with the outside is located on the side wall of the motor base.
In a preferred embodiment of the present invention, the position opened by the breathing hole is used as an air tightness detecting hole after the motor base, the controller and the motor end cover are assembled.
Since the technical scheme as above is used, the utility model discloses a direct gum of ventilated membrane to paste on the internal surface of motor base installation controller one side, through the L type breather hole on the motor base, play waterproof ventilative effect, external muddy water simultaneously, dust, gravel and sand can not direct action on waterproof ventilated membrane yet, ensure that product life and durability are better. In addition the one end of breathing hole and external intercommunication is located on the lateral wall of motor base, also be difficult for intaking. The position of the breathing hole can also be used as an air tightness detection hole after the controller and the rear cover are assembled, so that the dual-purpose effect is achieved.
Drawings
Fig. 1 is the schematic view of the structure of the motor base with the breathing hole of the utility model.
Fig. 2 is the schematic view of the structure of the motor base with the breathing hole and the waterproof and breathable film attached thereon.
Fig. 3 is a front view of the motor base of the present invention as seen from the side where the controller is installed.
Fig. 4 is a perspective view of the motor base of the present invention viewed from the side where the controller is installed.
Detailed Description
The present invention is described in detail below with reference to the attached drawings and the detailed description.
Referring to fig. 1 to 2, the breathing valve structure of the brushless motor controller for the cooling fan of the automobile shown in the figures comprises a motor base 10, wherein a breathing hole 20 is formed in the motor base 10, the breathing hole 20 is L-shaped, and a waterproof breathable film 30 is attached to an orifice 21 of one side 11 of the breathing hole 20, which is close to the motor base 10 and used for the controller, in a back adhesive manner. Through the L type breather 20 on the motor base 10, play waterproof ventilative effect, external muddy water, dust, gravel and sand also can not direct action on waterproof ventilated membrane 30 simultaneously, ensure that product life and durability are better. The port 22 at one end of the breathing hole 20 communicated with the outside is positioned on the side wall 12 of the motor base 10, so that water is not easy to enter
The position of the breathing hole 20 is used as an air tightness detection hole after the motor base 10, the controller and the motor end cover are assembled.
