Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to an air pipe fixing structure for motors. Background Art

[0002] The air pipe is a flexible tube that connects the inside and outside of a motor. In existing technology, a motor includes a stator, which contains liquid cooling oil that collects in the lower half of the stator. The stator has a stator mounting hole, and the air pipe is typically fixed directly to the stator mounting hole. When the motor starts operating, the liquid cooling oil shakes with the motor, and the end of the air pipe can easily fall out of the stator mounting hole and become immersed in the liquid cooling oil. This also makes it easy for the liquid cooling oil to splash into the air pipe, increasing the risk of liquid cooling oil overflowing through the air pipe. Improvements are needed in this area. Summary of the Invention

[0003] The utility model provides a new air pipe fixing structure for a motor to address the defects in the prior art such as the air pipe end being easily detached from the stator mounting hole and immersed in liquid cooling oil, which increases the degree of liquid cooling oil overflowing outward through the air pipe.

[0004] In order to solve the above technical problems, the present invention is implemented through the following technical solutions:

[0005] A trachea fixing structure for a motor includes a fixing base and a quick connector. The fixing base includes a vertical pipe and an undercut. The undercut is arranged on the lower side of the vertical pipe. A filter bucket is provided on the inner side wall of the vertical pipe. The inner diameter of the filter bucket gradually decreases downward in the height direction. A vent is passed through the bottom of the filter bucket. A flow channel is passed through the upper end of the quick connector. The lower end of the quick connector is inserted into the vertical pipe and plugged in. The flow channel is connected to the vent.

[0006] The air pipe is fixed to the stator through a quick connector, a fixing seat and a stator mounting hole, preventing the air pipe from being immersed in liquid cooling oil. Because the filter bucket is wide at the top and narrow at the bottom, the gas can flow out smoothly from the vent and flow channel when discharging the gas, while the liquid cooling oil has difficulty flowing out of the vent. When the gas is inhaled, the oil flowing back from above can smoothly pass through the filter bucket and drip into the liquid cooling oil in the stator, reducing the discharge amount of liquid cooling oil. By adjusting the connection angle between the undercut and the stator mounting hole, the filter bucket can be placed in a vertical direction, further preventing the liquid cooling oil from flowing out through the filter bucket.

[0007] Preferably, in the above-mentioned air pipe fixing structure for a motor, the fixing seat also includes a base frame, the vertical pipe is arranged at the upper end of the base frame, the undercut is arranged at the side end of the base frame, and the base frame surrounds the outside of the filter bucket.

[0008] The filter bucket can be shielded by the base frame to prevent the liquid cooling oil from splashing into the filter bucket when the motor is running.

[0009] Preferably, in the above-mentioned air pipe fixing structure for a motor, at least one clearance groove is provided at the end of the undercut, the clearance groove extends inwardly along the length direction of the undercut, and the width of the clearance groove gradually decreases inwardly along the length direction of the undercut.

[0010] The recessed groove facilitates pushing and gathering the undercut inward, thereby reducing the resistance encountered when the undercut is inserted into the stator mounting hole, improving the smoothness of the undercut insertion into the stator mounting hole, and facilitating assembly.

[0011] Preferably, in the above-mentioned air pipe fixing structure for a motor, the upper surface of the undercut is provided with an inclined surface, and the inclined surface gradually increases inwardly along the length direction of the undercut.

[0012] The inclined surface further reduces the resistance encountered when the undercut is inserted into the stator mounting hole, thereby further improving the smoothness of the undercut insertion into the stator mounting hole.

[0013] Preferably, in the above-mentioned air pipe fixing structure for a motor, a fixing ring is coaxially provided on the outside of the quick connector, and a fixing groove located above the filter bucket is opened on the inner side wall of the vertical pipe, and the fixing ring is inserted into the fixing groove and snap-fitted.

[0014] The quick connector is fixed to the vertical pipe by plugging and fitting the fixing ring and the fixing groove, which improves the convenience of assembling the quick connector and the fixing seat.

[0015] Preferably, in the above-mentioned air pipe fixing structure for a motor, the width of the fixing ring gradually increases upward along the height direction, and the fixing groove is adapted to the shape of the fixing ring.

[0016] The width of the fixing ring gradually increases upward along the height direction, thereby ensuring the stability of the fixing ring when inserted into the fixing groove and improving the smoothness of the fixing ring when inserted into the fixing groove.

[0017] Preferably, in the above-mentioned air pipe fixing structure for a motor, the quick connector includes an upper section and a lower section, the outer diameter of the upper section is larger than the outer diameter of the lower section, the outer diameter of the lower section is adapted to the inner diameter of the vertical pipe, and the lower surface of the upper section is in contact with the end of the vertical pipe; the fixing ring is arranged on the outer surface of the lower section.

[0018] The outer diameter of the upper section is larger than the inner diameter of the vertical pipe and the lower surface of the upper section is in contact with the end of the vertical pipe, thereby improving the sealing performance of the connection between the end of the vertical pipe and the quick connector and further improving the sealing performance of the overall structure.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-3 The present invention is further described in detail with reference to the following specific embodiments, but they are not intended to limit the present invention:

[0024] Example 1

[0025] like Figure 1-Figure 3 As shown, a trachea fixing structure for a motor includes a fixing base 1 and a quick connector 2. The fixing base 1 includes a vertical pipe 11 and an undercut 12. The undercut 12 is arranged on the lower side of the vertical pipe 11. A filter bucket 3 is provided on the inner wall of the vertical pipe 11. The inner diameter of the filter bucket 3 gradually decreases downward along the height direction. A vent 31 is passed through the bottom of the filter bucket 3; a flow channel 21 is passed through the upper end of the quick connector 2. The lower end of the quick connector 2 is inserted into the vertical pipe 11 and plugged in. The flow channel 21 is connected to the vent 31.

[0026] Preferably, the fixing base 1 further includes a base frame 13 , the vertical pipe 11 is arranged at the upper end of the base frame 13 , the undercut 12 is arranged at the side end of the base frame 13 , and the base frame 13 surrounds the outside of the filter bucket 3 .

[0027] Preferably, at least one clearance groove 121 is formed at the end of the undercut 12 , and the clearance groove 121 extends inwardly along the length direction of the undercut 12 , and the width of the clearance groove 121 gradually decreases inwardly along the length direction of the undercut 12 .

[0028] Preferably, an upper surface of the undercut 12 is provided with an inclined surface 122 , and the inclined surface 122 gradually increases inwardly along the length direction of the undercut 12 .

[0029] Preferably, a fixing ring 22 is coaxially provided on the outside of the quick connector 2, and a fixing groove 111 located above the filter bucket 3 is opened on the inner side wall of the vertical pipe 11, and the fixing ring 22 is inserted into the fixing groove 111 and snap-fitted.

[0030] Preferably, the width of the fixing ring 22 gradually increases upward along the height direction, and the fixing groove 111 is adapted to the shape of the fixing ring 22 .

[0031] Preferably, the quick connector 2 includes an upper section 200 and a lower section 201, the outer diameter of the upper section 200 is larger than the outer diameter of the lower section 201, the outer diameter of the lower section 201 is adapted to the inner diameter of the vertical pipe 11, and the lower surface of the upper section 200 is in contact with the end of the vertical pipe 11; the fixing ring 22 is arranged on the outer surface of the lower section 201.

[0032] Specifically, when fixing the quick connector 2 and the air pipe on the vertical pipe 11, first insert one end of the air pipe into the flow channel 21, then insert the lower section 201 into the vertical pipe 11 and make the lower surface of the upper section 200 press against the upper surface of the vertical pipe 11. At this time, the fixing ring 22 is inserted into the fixing groove 111 and fixed by clamping, so that the quick connector 2 and the air pipe can be fixed on the fixing seat 1.

[0033] When the fixing base 1 needs to be fixed on the stator, it is only necessary to align the end of the undercut 12 with the stator mounting hole and insert the undercut 12 into the stator mounting hole to complete the assembly of the fixing base 1 and the stator.

[0034] Because the filter bucket 3 is wide at the top and narrow at the bottom, when the gas is discharged, the gas can flow out smoothly from the vent hole 31 and the flow channel 21, while the liquid cooling oil is difficult to flow out from the vent hole 31; when the gas is inhaled, the oil refluxed from the top can smoothly pass through the filter bucket 3 and drip into the liquid cooling oil in the stator, reducing the discharge amount of the liquid cooling oil; by adjusting the connection angle between the undercut 12 and the stator mounting hole, the filter bucket 3 can be placed in the vertical direction, further preventing the liquid cooling oil from flowing out through the filter bucket 3.
