Technical Field

[0001] This utility model relates to the field of motor housing technology, and in particular to a housing structure that facilitates the discharge of gas from inside a motor. Background Technology

[0002] The motor housing is an important component of the motor, mainly responsible for mechanical support, heat dissipation, protection and electromagnetic shielding. Most motor housings have vents for venting the gas inside the motor.

[0003] In the prior art, since the air vents on the motor housing are mostly integrated with the motor housing, impurities will enter the air vents along with the gas when the gas passes through them. Over time, the impurities can easily clog the air vents and become difficult to clean, thus affecting the gas discharge. Utility Model Content

[0004] The purpose of this utility model is to provide a housing structure that facilitates the discharge of gas from inside the motor, thereby solving the problem mentioned in the background art where impurities enter the gas vent along with the gas, and over time, these impurities easily clog the vent and are difficult to clean, thus affecting the discharge of gas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a housing mechanism, comprising a motor housing, a connecting groove, a pin groove, a positioning ring, a positioning groove, an assembly positioning block, a mounting stop, a fixing hole, and an internal thread groove. An exhaust mechanism is provided inside the housing mechanism, comprising an exhaust pipe, an external threaded ring, a filter plate, a damping ring, and a groove. A heat dissipation mechanism is also provided inside the housing mechanism, comprising a heat-conducting plate, a heat-conducting connecting block, a heat dissipation plate, and heat dissipation fins.

[0006] In a preferred embodiment, the motor housing has a connecting groove inside, a pin groove at the bottom of the motor housing, and the bottom of the motor housing is fixedly connected to the top of the positioning ring.

[0007] In a preferred embodiment, the positioning ring has a positioning groove inside, the top two sides of the motor housing are fixedly connected to one side of the mounting positioning block, and the mounting positioning block has an installation stop inside.

[0008] In a preferred embodiment, the bottom of the motor housing is provided with a fixing hole, and the top of the fixing hole is provided with an internal thread groove.

[0009] In a preferred embodiment, the inner wall of the fixing hole is movably connected to the outer wall of the exhaust pipe, and the outer wall of one end of the exhaust pipe is fixedly connected to the inner wall of the external threaded ring.

[0010] In a preferred embodiment, the outer wall of the external threaded ring is threadedly connected to the inner wall of the internal threaded groove, and a damping groove is provided on the inner wall of the other end of the exhaust pipe.

[0011] In a preferred embodiment, the inner wall of the exhaust pipe is movably connected to the outer wall of the filter plate, the outer wall of the filter plate is fixedly connected to the inner wall of the damping ring, and the outer wall of the damping ring is movably connected to the inner wall of the damping groove. A groove is provided on the outer wall of the end of the exhaust pipe away from the external threaded ring.

[0012] In a preferred embodiment, the inner wall of the motor housing is fixedly connected to the outer wall of the heat-conducting plate, and the outer wall of the heat-conducting plate is fixedly connected to one side of the heat-conducting connecting block, and the outer wall of the heat-conducting connecting block is movably connected to the inner wall of the connecting groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when gas is discharged from inside the motor housing, impurities in the gas adhere to the inner wall of the exhaust pipe as it passes through the interior of the exhaust pipe. When the gas passes through the interior of the filter plate, the filter plate blocks the impurities, thereby reducing the discharge of impurities. When it is necessary to clean the interior of the exhaust pipe, the exhaust pipe is rotated, which in turn drives the external threaded ring to rotate on the inner wall of the internal threaded groove, so that the external threaded ring moves away from the interior of the internal threaded groove, and the exhaust pipe is then removed from the interior of the fixing hole. The filter plate is removed, and then the exhaust pipe and the filter plate are cleaned. The detachable exhaust pipe facilitates the cleaning of the interior of the exhaust pipe. The filter plate reduces the impact of impurities on the outer wall of the motor housing.

[0015] 2. In this utility model, when the motor housing is in use, the heat generated inside the motor housing is conducted to the heat-conducting plate, and then to the heat sink through the heat-conducting connecting block. The heat is then dissipated through the heat sink and heat sink fins. The heat dissipation effect of the motor housing is increased by setting the heat sink and heat sink fins.

[0028] In one embodiment, the positioning ring 104 has a positioning groove 105 inside, the top two sides of the motor housing 101 are fixedly connected to one side of the mounting positioning block 106, and the mounting positioning block 106 has an installation stop 107 inside.

[0029] Specifically: the installation of the stop 107 facilitates the positioning and assembly of the end cap, and the installation of the positioning block 106 facilitates the positioning and fixing of the assembly.

[0030] In one embodiment, a fixing hole 108 is provided at the bottom of the motor housing 101, and an internal thread groove 109 is provided at the top of the fixing hole 108.

[0031] Specifically: rotating the exhaust pipe 201 causes the external threaded ring 202 to rotate on the inner wall of the internal threaded groove 109, so that the external threaded ring 202 moves away from the inside of the internal threaded groove 109, thereby removing the exhaust pipe 201 from the inside of the fixing hole 108.

[0032] In one embodiment, the inner wall of the fixing hole 108 is movably connected to the outer wall of the exhaust pipe 201, and the outer wall of one end of the exhaust pipe 201 is fixedly connected to the inner wall of the external threaded ring 202.

[0033] Specifically: When the gas inside the motor housing 101 is discharged, the gas passes through the inside of the exhaust pipe 201. Impurities in the gas will adhere to the inner wall of the exhaust pipe 201. When the gas passes through the inside of the filter plate 203, the filter plate 203 blocks the impurities.

[0034] In one embodiment, the outer wall of the external threaded ring 202 is threadedly connected to the inner wall of the internal threaded groove 109, and a damping groove is provided on the inner wall of the other end of the exhaust pipe 201.

The outer wall of the heat-conducting connecting block 302 is movably connected to the inner wall of the connecting groove 102. The other side of the heat-conducting connecting block 302 is fixedly connected to the inner wall of the heat sink 303, and the outer wall of the heat sink 303 is fixedly connected to one side of the heat sink fin 304.

The heat dissipation effect of the motor housing 101 is increased by setting the heat sink 303 and the heat dissipation fins 304.

[0040] Working principle: When gas is discharged from inside the motor housing 101, it passes through the inside of the exhaust pipe 201. Impurities in the gas adhere to the inner wall of the exhaust pipe 201. When the gas passes through the inside of the filter plate 203, the filter plate 203 blocks the impurities, thereby reducing the discharge of impurities. When it is necessary to clean the inside of the exhaust pipe 201, the exhaust pipe 201 is rotated, which in turn drives the external threaded ring 202 to rotate on the inner wall of the internal threaded groove 109, so that the external threaded ring 202 moves away from the inside of the internal threaded groove 109, and then the exhaust pipe 201 is removed from the inside of the fixing hole 108. The filter plate 203 is removed and then the exhaust pipe 201 and the filter plate 203 are cleaned. When the motor housing 101 is in use, the heat generated inside the motor housing 101 is conducted to the heat-conducting plate 301, and then to the heat sink 303 through the heat-conducting connecting block 302. Then the heat is discharged through the heat sink 303 and the heat sink fins 304.
