Description

Technical Field

[0001] The invention relates to the technical field of servo motors, and in particular to a high-sealing and high-insulation end cover assembly for a micro servo motor. Background Art

[0002] As customers' requirements for servo motors continue to increase, the reliability and precision requirements for servo motors have also been continuously improved. As an important component of the servo motor, the end cover of the servo motor determines the protection and service life of the servo motor. The end cover structure of the traditional motor is a die-cast structure, and the shaft generally extends out of the end cover. Therefore, the end cover has a poor protective effect on the shaft.

[0003] The Chinese patent with publication number CN117335602A discloses an end cover assembly of a servo motor, including a motor end cover and a surrounding sealing assembly; the motor end cover is provided with an axial hole. The surrounding sealing assembly includes a friction block, a first driving member, and a second driving member; four friction blocks are respectively arranged at four corners of a virtual rectangle formed around the axial hole; the four friction blocks enclose an interlaced space; the interlaced space has a continuous circumferential sealing surface; the first driving member has an active state of moving along a preset direction under the action of its own gravity, and has an active driving state of driving the friction blocks on the two wide sides of the virtual rectangle to move closer to each other in the active state; the second driving member has a passive driving state of driving the friction blocks on the two long sides of the virtual rectangle to move closer to each other in the active driving state.

[0004] However, the above-mentioned disclosed scheme has the following shortcomings: the existing micro servo motor end cover cannot dissipate heat for the motor during use, which can easily cause damage to the motor at high temperatures. At the same time, the inside of the end cover cannot be dust-removed, and the dust may enter the motor after long-term use and affect the operation of the motor. Therefore, it is necessary to invent an end cover assembly for a micro servo motor to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to address the problem in the background technology that the end cover cannot dissipate heat for the motor and cannot handle dust accumulation, and to propose a high-sealing and high-insulation end cover assembly for a micro servo motor.

[0006] The technical solution of the present invention is: a high-sealing and high-insulation end cap assembly for a micro servo motor, comprising a micro motor, an output shaft is arranged at the output end of the micro motor, and an end cap housing is arranged at the end of the micro motor; and further comprising:

[0007] The heat dissipation mechanism is arranged inside the end cover shell and is used to quickly discharge the heat inside the micro motor;

[0008] And a dust removal mechanism is arranged on a side of the end cover away from the micro motor and is used for absorbing dust from the heat dissipation mechanism and the interior of the end cover shell.

[0009] Preferably, the heat dissipation mechanism includes a circular gear 1 arranged on the outside of the output shaft, a sliding ring is arranged on the side of the circular gear 1, a circular ring slide rail is slidably arranged on the outside of the sliding ring, a mounting plate is arranged on the side of the circular ring slide rail away from the circular gear 1, a mounting block is arranged on the side of the mounting plate, a circular gear 2 is meshed on the side of the circular gear 1, a connecting shaft 1 is arranged at the axis center of the circular gear 2, a circular gear 3 is meshed on the side of the circular gear 2 away from the circular gear 1, a connecting shaft 2 is arranged at the axis center of the circular gear 3, and a heat exchange component is rotatably arranged on the side of the circular gear 3.

[0010] Preferably, the heat exchange assembly includes a ventilation box rotatably arranged on the outside of the second connecting shaft, a connecting ring arranged on the outside of the second connecting shaft, a stirring plate arranged on the outside of the connecting ring, a connecting pipe arranged on the side of the ventilation box, a closing plate arranged on the outside of the connecting pipe, an air inlet pipe arranged on the top of the ventilation box, a one-way valve 1 arranged inside the air inlet pipe, an exhaust pipe arranged on the bottom of the ventilation box, a one-way valve 2 arranged inside the exhaust pipe, a refrigeration device arranged on the end of the air inlet pipe away from the ventilation box, and a connecting block arranged at the bottom of the refrigeration device.

[0011] Preferably, the dust removal mechanism comprises a fixed ring, a gear ring is arranged on the outer side of the fixed ring, a dust suction assembly is arranged on the top of the gear ring, and a connecting assembly is arranged inside the fixed ring.

[0012] Preferably, the dust collection assembly includes a circular gear four meshing with the gear ring, a connecting shaft three is arranged at the axis center of the circular gear four, and an air suction fan is arranged on the outer side of the connecting shaft three.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] 1. Through the setting of the dust removal mechanism, the pull rod is used to control the plug rod to be stuck in the output shaft. In this way, the dust removal mechanism can be driven to operate when the motor is started, so that the suction fan can suck out the dust in the end cover shell. At the same time, part of the internal hot air can be sucked out for preliminary heat dissipation, which can effectively reduce the accumulation of dust inside the motor, maintain the cleanliness of the inside of the motor, help to maintain the good operating condition of the motor, extend its service life, and avoid the accumulation of dust leading to poor heat dissipation of the motor, increased wear of mechanical parts and other problems.

[0016] 2. Through the setting of the heat dissipation mechanism, the servo motor can also drive the circular gear to rotate when working, thereby driving the stirring plate to rotate. In this way, the air inside the servo motor can be quickly replaced, and effective heat dissipation can be performed, which can quickly reduce the temperature inside the motor and avoid the motor's performance degradation or damage due to overheating. It helps to maintain the stability of the motor's performance and ensure that it can work normally under various working conditions. At the same time, it can reduce the thermal stress of the internal components of the motor, thereby extending the service life of the motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiment 2

[0030] like Figure 5-Figure 6 As shown, the present invention proposes a high-sealing and high-insulation end cover assembly for a micro servo motor. Compared with the first embodiment, this embodiment introduces the structure of the dust removal mechanism 5 in detail.

[0031] Specifically, the dust removal mechanism 5 includes a fixed ring 501, a gear ring 502 is arranged outside the fixed ring 501, a dust collection assembly is arranged on the top of the gear ring 502, and a connecting assembly is arranged inside the fixed ring 501.

Since the number of teeth of the circular gear 4 503 is less than that of the gear ring 502, when the gear ring 502 rotates one circle, the circular gear 4 503 can be driven to rotate several circles, so that the rapid rotation generates greater suction.
