Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a windshield wiper control motor. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. It is represented by the letter M in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. A generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. Currently, the most common method is to use heat energy, water energy, etc. to drive the generator rotor to generate electricity.

[0003] The utility model patent application document with publication number "CN211606250U" discloses a wiper control motor, which is mainly composed of a shell, a reinforcement ring, a first reinforcement rib, a first ear plate, an end cover, a second ear plate, a second reinforcement rib, a wind shield, a third ear plate and a third reinforcement rib. The technical solution increases the firmness of the shell by setting the reinforcement ring and the first reinforcement rib, and at the same time strengthens the protection of the components inside the shell. By connecting the first ear plate, the second ear plate and the second reinforcement rib, and the third ear plate and the third reinforcement rib, the thickness of the connection is increased, making the connection not easily damaged.

[0004] The wiper control motor disclosed in the above document has the following defects: the wiper control motor uses a wind hood to draw external wind into the interior of the shell to dissipate the heat generated by the electronic components inside the shell. However, in hot weather, the heat accumulates inside the shell and is difficult to discharge only through the wind hood, which in turn affects the subsequent service life of the wiper control motor.

[0005] It can be seen from this that the existing wiper control motor does not have a good heat dissipation structure, and it is necessary to improve the existing deficiencies and provide a wiper control motor. Utility Model Content

[0028] The heat dissipation assembly 8 includes a connection tube 801, the outer surface of the connection tube 801 is provided with a plurality of heat dissipation fins 802, the interior of the connection tube 801 is provided with a plurality of first connection blocks 803, the outer surface of the housing 1 is provided with a plurality of mounting grooves, the mounting grooves correspond to the first connection blocks 803 one by one, and the first connection blocks 803 are mounted in the interior of the mounting grooves;

[0029] The outer surface of the motor shaft 6 is provided with a spiral blade 9, the outer surface of the cover body 3 is provided with an air inlet 301, and the outer surface of the cover plate 2 is provided with an air outlet 201;

[0030] Through the coordinated use of the connecting tube 801, the heat dissipation fins 802 and the first connecting block 803, the heat accumulated on the inner surface of the housing 1 can be guided to the outside to dissipate the heat of the housing 1. At the same time, the motor shaft 6 drives the spiral blades 9 to rotate during the rotation process. The rotation of the spiral blades 9 generates suction, which can accelerate the flow of air, so that the outside air enters the interior of the housing 1 through the air inlet 301 to dissipate the heat of the electronic components inside the housing 1, and then is discharged through the air outlet 201, achieving a better heat dissipation effect.

[0031] The fixing assembly 4 includes a second connecting block 401, one end of which is mounted on the outer surface of the cover plate 2, a mounting hole 302 is provided on the outer surface of the cover body 3, the second connecting block 401 is mounted in the mounting hole 302, a chamber 402 is provided in the second connecting block 401, a slide plate 403 is slidably connected to the chamber 402, two slide plates 403 are set and symmetrically distributed, a spring 404 is installed between the two slide plates 403, a fixing block 405 is provided on one end of the slide plate 403 away from the spring 404, one end of the fixing block 405 passes through the second connecting block 401 and extends outward, and the outer surface of the fixing block 405 abuts against the outer surface of the cover body 3;

[0032] The outer surface of the fixing block 405 is provided with anti-slip stripes;

[0033] By squeezing the fixing blocks 405 at both ends of the second connection block 401, the two fixing blocks 405 push the slide plate 403 to move toward one end close to each other. When the outer surface of the fixing block 405 is flush with the outer surface of the second connection block 401, the cover body 3 can be pulled upward to disengage the second connection block 401 from the mounting hole 302, and the housing 1 and the cover body 3 are separated. This arrangement replaces the traditional bolt fixing method, facilitates the maintenance of the electronic components inside the housing 1, and has good practicality.

[0034] One end of the cover body 3 is clamped with a dustproof net 10;

[0035] The dustproof net 10 can block impurities in the air and prevent the impurities from entering the interior of the housing 1 and affecting the service life of the electronic components in the housing 1 .

[0036] When in use, first install the wiper control motor at the place to be worked. When a large amount of heat accumulates inside the shell 1, the heat accumulated on the inner surface of the shell 1 can be guided to the outside to dissipate the heat of the shell 1 through the cooperation between the connecting tube 801, the heat dissipation fins 802 and the first connecting block 803. At the same time, the motor shaft 6 drives the spiral blades 9 to rotate during the rotation. The rotation of the spiral blades 9 generates suction, which can accelerate the flow of air, so that the outside air enters the shell 1 through the air inlet 301 to dissipate the heat of the electronic components inside the shell 1, and then is discharged through the air outlet 201, achieving a better heat dissipation effect. In the process of the outside air entering the shell 1, the dustproof net 10 is set to block impurities in the air to prevent impurities from entering the shell 1 and affecting the service life of the electronic components in the shell 1. When the electronic components in the shell 1 need to be repaired, the wiper control motor is first removed, and the fixing blocks 405 at both ends of the second connecting block 401 are squeezed so that the two fixing blocks 405 push the slide plate 403 The cover 3 is moved toward one end close to each other. When the outer surface of the fixing block 405 is flush with the outer surface of the second connecting block 401, the cover 3 can be pulled upward to disengage the second connecting block 401 from the mounting hole 302, and the shell 1 and the cover 3 are separated. This arrangement replaces the traditional bolt fixing method, which is convenient for repairing the electronic components inside the shell 1. After the repair is completed, the second connecting block 401 is aligned with the mounting hole 302, and the cover 3 is pushed downward. Since the outer surface of the fixing block 405 is provided with an inclined surface, the second connecting block 401 is disengaged from the mounting hole 302 during the pushing process. During the process, the two fixed blocks 405 push the slide plate 403 to move toward one end that is close to each other. When the outer surface of the fixed block 405 is flush with the outer surface of the second connecting block 401, the second connecting block 401 can slide in the mounting hole 302. When the outer surface of the cover body 3 abuts against the outer surface of the shell 1, the spring 404 restores its elasticity to push the slide plate 403 and the fixed block 405 to move outward, so that the outer surface of the fixed block 405 abuts against the outer surface of the cover body 3, completing the fixed installation of the cover body 3 and the shell 1, which has better practicality.
