Description of the embodiments
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
As shown in fig. 1 to 9, the aluminum front end cover of the automobile generator of the present utility model comprises a housing 1 and an end cover 2 connected to the housing 1. The inside of the shell 1 is provided with a mounting sleeve 4 for mounting the generator shaft 3, and the mounting sleeve 4 is connected with the inner wall of the shell 1 through a plurality of reinforcing ribs 5. One end of the generator shaft 3 is connected with the rotor, the other end passes through the mounting sleeve 4 and is connected with the fan 6, the fan 6 is rotated by the driving of the generator shaft 3, so that external air flow can be guided into the end cover 2, the blocking body 7 is blown by strong air flow to deform, and the air flow passes through the contact section 9 and the inner wall of the shell 1.
Moreover, since the guide section 8 has a certain deformation strength, the distance of the opening and closing passage between the contact section 9 and the inner wall of the housing 1 is limited. The airflow entering from the heat dissipation chamber 10 can be accelerated through the smaller opening and closing channels, so that the airflow is blown into the installation chamber, the discharge of the hot airflow in the installation chamber is accelerated, and the heat dissipation efficiency is improved.
The end cover 2 is connected with the shell 1 through bolts, and the end cover 2 is provided with a radiating hole 11 through which air passes for introducing external air flow. The heat dissipation holes 11 can prevent larger insects or impurities from entering, and the generator separates the installation chamber from the heat dissipation chamber 10 through the blocking piece 12 in a non-working state, and the installation chamber is communicated with the heat dissipation chamber 10 in working.
One end face of the mounting sleeve 4 is a mounting chamber for placing a rotor and a stator, and the other end face is a heat dissipation chamber 10 for placing a heat dissipation fan 6. The middle of the mounting sleeve 4 is provided with a mounting hole 13 for mounting the generator shaft 3.
The mounting sleeve 4 is provided with a blocking piece 12, and the blocking piece 12 can deform to communicate the mounting chamber with the heat dissipation chamber 10 when being subjected to external force. The blocking piece 12 is composed of a sleeve body 14 and blocking bodies 7 which are uniformly distributed on the sleeve body 14, a movable area 15 for placing the blocking bodies 7 is arranged between the reinforcing ribs 5 and the reinforcing ribs 5, and a clearance groove 16 for placing the reinforcing ribs 5 is reserved between the blocking bodies 7 and the blocking bodies 7. The middle of the sleeve body 14 is provided with a fixing hole 17, and the mounting sleeve 4 is positioned in the fixing hole 17.
The surface of the installation sleeve 4 is provided with a concave groove 18, and the sleeve body 14 is provided with a limit body 19 matched with the concave groove 18.
The blocking body 7 consists of an arc-shaped section 20, a guide section 8 and a contact section 9, wherein after the contact section 9 is installed, contact connection exists between the contact section and the inner wall of the shell 1, and the blocking body 7 is in a natural state at the moment and is not stressed to press the inner wall of the shell 1.
The mounting sleeve 4 is provided with an arc-shaped part 21 matched with the arc-shaped section 20, and the contact section 9 is contacted with the inner wall of the shell 1. The blocking body 7 is deformed by the external air flow coming out of the fan 6, the contact section 9 being out of contact with the inner wall of the housing 1.
When the blocking piece 12 is installed, the fixing hole 17 in the blocking body 7 is directly aligned with the installation sleeve 4, and the blocking piece 12 is fixed through the cooperation of the concave groove 18 and the limiting body 19. In addition, the arc-shaped section 20 extends towards and can be matched with the arc-shaped part 21, so that the position of the blocking body 7 is limited, and the contact section 9 can only deform downwards under the stress.
