Description

Technical Field

[0001] The utility model relates to the technical field of automobile motors, in particular to an automobile motor end cover with good sealing performance. Background Art

[0002] With the continuous development of the automotive industry, the types of automotive motors produced are also increasing. An automotive motor is a motor that rotates in a magnetic field through an energized coil to drive the starter rotor to rotate. The small gear on the rotor drives the engine flywheel to rotate, thereby driving the crankshaft to rotate and start the car. The automotive motor is assembled from a variety of parts, and the front end cover is one of them.

[0003] The utility model with publication number CN216530841U provides a highly sealed front end cover for a new energy vehicle motor. This motor front end cover is designed to solve the technical problem that in the prior art, the motor front end cover has gaps on its surface, making it impossible to seal the motor. If it is accidentally stained with water, it will cause a short circuit in the motor circuit, resulting in the vehicle not being able to operate normally. The motor front end cover includes a motor front end cover body, a mounting sleeve arranged on the front side of the motor front end cover body for mounting the motor shaft, a heat dissipation module arranged on the outside of the mounting sleeve for heat dissipation of the motor, a mounting module arranged on the outside of the motor front end cover body for installation, a protective module arranged on the inside of the motor front end cover body for buffering external forces, and a reinforcement module arranged on the outside of the protective module for reinforcement. The motor front end cover has no gaps on the outside and fits tightly with the motor housing, thereby sealing the entire motor and preventing water from getting inside the motor and causing a short circuit.

[0004] When in use, multiple bolts are used to fix the front cover and the automobile motor together, which is inconvenient to install and remove, and the bolts are very easy to loosen. Once loosened, the sealing between the front cover and the automobile motor will be affected, resulting in a poor sealing effect.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0020] like Figures 1 to 4 As shown, the utility model provides an automobile motor end cover with good sealing performance, comprising: an end cover assembly 2, an automobile motor body 3, a connecting assembly 5 for connecting, a fixing assembly 1 for fixing the end cover assembly 2 and the connecting assembly 5 together, and a locking structure 4 for reinforcing the fixing assembly 1.

[0021] The end cover assembly 2 includes: a motor front end cover 201, a positioning boss 204 fixedly mounted on the motor front end cover 201, and a sealing ring 203 mounted on the positioning boss 204, which is used to enhance the sealing between the motor front end cover 201 and the automobile motor body 3. An elastic snap ring 202 is installed on the positioning boss 204 on one side of the sealing ring 203, which is used to reduce the vibration impact of the automobile motor body 3 on the fixed snap ring 101 when in use. The diameter of the elastic snap ring 202 is larger than the diameter of the sealing ring 203.

[0022] The fixing assembly 1 is composed of a fixing snap ring 101 and a rotatable fixing bolt 103. The inner side of the fixing snap ring 101 is provided with a positioning groove 102 that matches the elastic snap ring 202 and is used to limit the elastic snap ring 202 so that it is not easily displaced.

[0023] The connecting component 5 includes: a connecting boss 501, and a limiting groove 502 provided on the inner side of the connecting boss 501 and adapted to the positioning boss 204. The limiting groove 502 is engaged with the positioning boss 204 to enhance the connection stability between the automobile motor body 3 and the motor front end cover 201.

[0024] The first limit block 205 and the second limit block 503 are respectively installed on the front end cover 201 of the motor and the connecting boss 501. The inner side of the fixed retaining ring 101 is provided with a first limit groove 104 and a second limit groove 105 corresponding to it. The first limit block 205 is engaged with the first limit groove 104, and the second limit block 503 is engaged with the second limit groove 105, which can play a positioning role for the fixed retaining ring 101 and enhance its installation stability.

[0025] In the present invention, the provision of the elastic snap ring 202 can effectively reduce the vibration effect of the automobile motor body 3 on the fixing snap ring 101 when in use, reduce the vibration of the fixing bolt 103, and avoid the situation where it becomes loose due to vibration. At the same time, the elastic snap ring 202 can also further enhance the sealing between the motor front end cover 201 and the automobile motor body 3.

[0026] The locking structure 4 includes: a connecting base 401 fixedly mounted above the automobile motor, and a rotatable locking bolt 402 mounted on the connecting base 401. By tightening the locking bolt 402, it contacts the fixing bolt 103, which can limit and reinforce the fixing bolt 103 to prevent it from loosening.

[0027] Working principle: push the positioning boss 204 into the limiting groove 502, the sealing ring 203 abuts against the inner wall of the limiting groove 502, the elastic snap ring 202 contacts the connecting boss 501, put on the fixing snap ring 101, the first limiting block 205 is clamped with the first limiting groove 104, the second limiting block 503 is clamped with the second limiting groove 105, the elastic snap ring 202 is clamped into the positioning groove 102, tighten the fixing bolt 103, fix the fixing snap ring 101, complete the connection between the motor front end cover 201 and the automobile motor body 3, the sealing ring 203 can improve the sealing between the front end cover 201 of the motor and the automobile motor body 3. The elastic snap ring 202 can effectively reduce the vibration impact of the automobile motor body 3 on the fixing snap ring 101 when in use, reduce the vibration of the fixing bolt 103, and achieve the purpose of preventing loosening. At the same time, it can also further enhance the sealing between the front end cover 201 of the motor and the automobile motor body 3. Tightening the locking bolt 402 so that it contacts the fixing bolt 103 can limit and reinforce the fixing bolt 103, thereby improving its installation stability and preventing it from loosening.
