[0030] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0031] An embodiment of the present disclosure provides a motor, as Figure 1As shown in the figure, the motor includes a housing 1, a rotor structure 2, a stator structure 3, and a heat dissipation structure 4. The housing 1 includes a base 11, a top cover 12, and a drive connector 13. The base 11 and the top cover 12 are movably connected and define an accommodation cavity 10. The drive connector 13 is connected to the base 11 and the top cover 12 respectively, and can drive the top cover 12 to move relative to the base 11. The volume of the accommodation cavity 10 changes with the movement of the top cover 12. The rotor structure 2 is connected to the base 11 and is located in the accommodation cavity 10. The axis direction of the rotating shaft 21 of the rotor structure 2 is perpendicular to the movement direction of the top cover 12. The stator structure 3 is connected to the base 11 and is located in the accommodation cavity 10. The stator structure 3 is sleeved outside the rotor structure 2.

[0032] The heat dissipation structure 4 includes a cover body 41 and a fan blade 42. The fan blade 42 is located inside the cover body 41 and is connected to one end of the rotating shaft 21. The cover body 41 is connected to the base 11. A communication channel 40 is provided in the side wall of the base 11. One end of the communication channel 40 communicates with the inside of the cover body 41. When the top cover 12 is in the first position, the other end of the communication channel 40 communicates with the accommodation cavity 10. Or, when the top cover 12 is in the second position, the other end of the communication channel 40 is located outside the accommodation cavity 10. Among them, the volume of the accommodation cavity 10 corresponding to when the top cover 12 is in the first position is larger than the volume of the accommodation cavity 10 corresponding to when the top cover 12 is in the second position.

[0033] When the motor provided by the embodiment of the present disclosure is in use, since the base 11 and the top cover 12 in the motor are movably connected, the volume of the accommodation cavity 10 can be changed by moving the top cover 12. When the top cover 12 is in the first position, the volume of the corresponding accommodation cavity 10 is the largest. In this way, the pressure of the gas inside the motor can be reduced by increasing the volume of the accommodation cavity 10. After the pressure decreases, according to Bernoulli's equation, the flow velocity of the gas will increase. Therefore, by increasing the volume of the accommodation cavity 10, the air flow circulation speed inside the motor can be relatively increased, and further the heat dissipation capacity of the accommodation cavity 10 for the heat generated by the stator structure 3 and the rotor structure 2 is also improved, that is, the heat dissipation efficiency is improved.

[0034] Moreover, since the fan blade 42 is provided inside the cover body 41 and the fan blade 42 rotates together with the rotating shaft 21, when the top cover 12 is in the first position, at this time, the fan blade 42 can be used as a blower to blow air into the accommodation cavity 10 to further accelerate the air flow circulation speed inside the accommodation cavity 10, thereby greatly improving the heat dissipation effect inside the accommodation cavity 10.

[0035] Continue to refer to Figure 1, optionally, the driving connecting member 13 includes a connecting plate 131 and a telescopic rod 132. Two ends of the telescopic rod 132 are respectively connected to the top cover 12 and the connecting plate 131. The axial direction of the telescopic rod 132 is perpendicular to the axial direction of the rotating shaft 21. The connecting plate 131 is located on the side of the top cover 12 away from the accommodating cavity 10, and the connecting plate 131 is connected to the base 11.

[0036] In the above implementation, the driving connecting member 13 is set as structures such as the connecting plate 131 and the telescopic rod 132. In this way, the telescopic rod 132 can be connected to the base 11 through the connecting plate 131, and then the top cover 12 can be movably covered on the top of the base 11 through the telescopic rod 132, so as to realize the change of the volume of the accommodating cavity 10.

[0037] Exemplarily, the telescopic rod 132 is an electric telescopic rod, and the telescopic rod 132 is connected to an external power supply through a cable. In this way, the telescopic rod 132 can be controlled to expand and contract, so as to move the top cover 12 and change the volume of the accommodating cavity 10.

[0038] Figure 2 Yes Figure 1 is a cross-sectional view along the C-C direction, combined with Figure 2 , optionally, the top cover 12 is an arc-shaped structure. The center of the circle of the top cover 12 is located inside the accommodating cavity 10. In this way, the volume of the accommodating cavity 10 can be further increased through the arc-shaped structure, so as to increase the heat dissipation space inside the motor.

[0039] Optionally, the connecting plate 131 is an arc-shaped structure, and the connecting plate 131 is concentrically arranged with the top cover 12. Along the arc length direction of the top cover 12, the connecting plate 131 is located in the middle of the top cover 12. In this way, the connecting plate 131 and the top cover 12 can be stably connected, and under the action of the telescopic rod 132, it is ensured that the top cover 12 can move stably.

[0040] Continue to refer to Figure 1 and Figure 2 , the base 11 includes a bottom shell 111, a first end plate 112 and a second end plate 113. The bottom shell 111 has two end faces arranged oppositely along the axial direction of the rotating shaft 21. The two end faces, the first end plate 112 and the second end plate 113 are arranged oppositely, the first end plate 112 and the second end plate 113 are respectively connected to the two end faces of the bottom shell 111, and the second end plate 113 is connected to the connecting plate 131. The communication channel 40 includes a plurality of first heat dissipation holes 1131 in the second end plate 113, and the plurality of first heat dissipation holes 1131 are communicated with the inside of the cover body 41.

[0041] In the above implementation, the above structure can be connected to both ends of the bottom case 111 through the first end plate 112 and the second end plate 113 respectively, so as to provide an installation basis for the movable connection of the top cover 12. At the same time, the first heat dissipation hole 1131 can be used to communicate the accommodating cavity 10 with the cover body 41, so as to change the communication relationship between the accommodating cavity 10 and the cover body 41 when the top cover 12 is located at different positions.

[0042] Exemplarily, the first end plate 112 and the second end plate 113 have the same structure, both are arc-shaped plate structural members, and both are cemented carbide structural members. This facilitates connection to the circular end faces at both ends of the bottom case 111.

[0043] Optionally, a plurality of second heat dissipation holes are provided on the first end plate 112. This can further increase the heat dissipation effect inside the accommodating cavity 10.

[0044] Optionally, the housing 1 further includes a drying box 14. The drying box 14 is located outside the accommodating cavity 10, and the drying box 14 is connected to one side of the first end plate 112. The inside of the drying box 14 is communicated with the outside, and the inside of the drying box 14 is communicated with the second heat dissipation holes.

[0045] In the above implementation, by arranging the drying box 14 on the first end plate 112, this can prevent moist air flow and dust from entering the inside of the accommodating cavity 10, affecting the normal operation of the motor.

[0046] Exemplarily, a retaining net is provided on both the first heat dissipation hole 1131 and the second heat dissipation holes. This can block foreign impurities from entering the inside of the accommodating cavity 10 through the retaining net.

[0047] Exemplarily, the drying box 14 includes a box body with filter holes and filled with activated carbon.

[0048] Exemplarily, the bottom case 111 includes a U-shaped plate 1111, a first side plate 1112 and a second side plate 1113. The first side plate 1112 and the second side plate 1113 are arranged oppositely and are respectively connected to both ends of the U-shaped plate 1111 in the length direction. The first side plate 1112 is connected to the first end plate 112, and the second side plate 1113 is connected to the second end plate 113.

[0049] The above structure can easily and simply form the bottom case 111, which can facilitate its cooperation with the first end plate 112 and the second end plate 113.

[0050] Exemplarily, the first side plate 1112 and the second side plate 1113 have the same structure, both are circular plate structural members.

[0051] Figure 3 Yes Figure 1 The enlarged view of the A position in, combined with Figure 3, the outer peripheral wall of the first side plate 1112 facing the first end plate 112 has a first arc-shaped slot, and the first end plate 112 is provided with a first arc-shaped insertion plate 1122 located in the first arc-shaped slot. The first arc-shaped insertion plate 1122 and the first side plate 1112 are connected together by fastening screws.

[0052] The outer peripheral wall of the second side plate 1113 facing the second end plate 113 also has an arc-shaped slot, and the second end plate 113 is also provided with an arc-shaped insertion plate located in the arc-shaped slot. The arc-shaped insertion plate on the second end plate 113 and the second side plate 1113 are connected together by fastening screws.

[0053] The first side plate 1112 and the first end plate 112 can be conveniently positioned together through the slot and the insertion plate, and the second side plate 1113 and the second end plate 113 can be positioned together. Then, the first side plate 1112 and the first end plate 112, and the second side plate 1113 and the second end plate 113 are fixed through fastening screws.

[0054] Optionally, the opposite side surfaces of the first side plate 1112 and the second side plate 1113 respectively have two limit blocks 1114. The two limit blocks 1114 on the first side plate 1112 are symmetrically arranged about the central axis of the top cover 12, and the two limit blocks 1114 on the second side plate 1113 are also symmetrically arranged about the central axis of the top cover 12. All the limit blocks 1114 are located in the same horizontal plane. When the top cover 12 is in the second position, the top cover 12 contacts the limit blocks 1114.

[0055] In the above implementation, the limit blocks 1114 are used to support the top cover 12, so that the top cover 12 can stably cover the top of the base 11 even when not subjected to the pulling force of the telescopic rod 132.

[0056] Exemplarily, in order to facilitate the handling of the motor, the outer wall of the base 11 has two U-shaped handles 114, and the two U-shaped handles 114 are symmetrically connected to both sides of the base 11 with respect to the central axis of the top cover 12.

[0057] Continue to refer to Figure 1 and Figure 2 , the housing 1 further includes a support 15, the support 15 is connected to one side of the base 11, and the support 15 and the top cover 12 are respectively located on both sides of the base 11.

[0058] In the above implementation, since the outer wall of the base 11 is a circular structure, the placement of the motor can be facilitated by arranging the support 15.

[0059] Optionally, the inside of the rotating shaft 21 has a water cooling groove 211, and the extending direction of the water cooling groove 211 is the same as the axial direction of the rotating shaft 21.

[0060] The heat dissipation structure 4 further includes a water cooling component 44. The water cooling component 44 is located inside the cover body 41. The water cooling component 44 is connected to the rotating shaft 21 and is used to input cooling liquid into the water cooling groove 211.

[0061] In the above implementation, the above structure can transport the coolant inside the rotating shaft 21 through the water cooling component 44 to further cool the rotating shaft 21.

[0062] Optionally, the water cooling component 44 includes an input water cooling pipe 441, an output water cooling pipe 442, a first sealing box 443, and a water cooling box 444. The water cooling box 444 is inside the cover body 41, and a water pump 4441 is included in the water cooling box 444. One end of the input water cooling pipe 441 is connected to the output port of the water pump 4441, and the other end of the input water cooling pipe 441 is located inside the water cooling groove 211 and has a gap with the water cooling groove 211.

The inside of the first sealing box 443 is communicated with the water cooling groove 211. The water cooling box 444 is connected inside the cover body 41.

[0063] In the above implementation, with the above structure setting, under the action of the water pump 4441, the coolant in the water cooling box 444 can be input into the water cooling groove 211 through the input water cooling pipe 441, and at the same time, the coolant in the water cooling groove 211 can be transported to the water cooling box 444 to form a circulation channel between the water cooling groove 211 and the water cooling box 444, so that the cooling liquid can flow out of the water cooling box 444 and enter the water cooling groove 211, thereby dissipating heat from the rotating shaft 21 and further improving the heat dissipation effect of the rotor structure 2.

[0064] In addition, the first sealing box 443 is used to seal the inside of the water cooling groove 211 so that the coolant flowing into the water cooling groove 211 will not be exposed.

[0065] Optionally, the water pump 4441 is electrically connected to an external power supply through a circuit. This can quickly control the start and stop of the water pump 4441.

[0066] Exemplarily, in order to improve the heat dissipation effect on the rotating shaft 21, the input water cooling pipe 441 may include a first pipe section 4411, a second sealing box 4412, and a second pipe section 4413 that are sequentially communicated. Among them, the first pipe section 4411 is located inside the cover body 41, the second sealing box 4412 is located inside the first sealing box 443 and is connected to the inner wall of the first sealing box 443 through a connecting rod.

In this way, the internal communication between the second pipe segment 4413 and the water cooling tank 211 can be conveniently realized.

[0068] In this embodiment, both the input water cooling pipe 441 and the output water cooling pipe 442 are made of cemented carbide steel pipes. In this way, the service life of the water cooling assembly 44 can be extended.

[0069] Figure 4 Yes Figure 1 The enlarged view at B in, in combination with Figure 4 , optionally, in order to improve the sealing effect, a sealing ring is provided between the rotating shaft 21 and the first sealing box 443. One end of the rotating shaft 21 facing the first sealing box 443 has a sealing groove, and the sealing ring is located in the sealing groove.

[0072] The plurality of support rods 446 include multiple groups distributed along the axial direction of the rotating shaft 21, and each group of support rods 446 includes several support rods 446, and the several support rods 446 are evenly distributed along the circumferential direction of the rotating shaft 21.

[0073] In the above implementation manner, the support rod 446 is used to support the input water cooling pipe 441 located in the water cooling tank 211, so that the second pipe segment 4413 of the input water cooling pipe 441 is located in the middle of the rotating shaft 21, and further, the coolant can be evenly located inside the rotating shaft 21, thereby improving the heat dissipation effect.

[0074] Figure 5 is the structural schematic diagram of the water cooling box provided by the embodiment of the present disclosure, in combination with Figure 5 , optionally, the water cooling assembly 44 further includes a plurality of heat sinks 447, and the heat sinks 447 are attached to the outer wall of the water cooling box 444.

[0075] In the above implementation manner, by providing the heat sinks 447 on the outer wall of the water cooling box 444, the water cooling box 444 can be further cooled through the heat sinks 447 to ensure that the temperature of the coolant flowing through the inside of the water cooling box 444 is relatively low.

[0076] Optionally, in order to add coolant to the water cooling box 444, a liquid adding pipe 449 is further connected to the water cooling box 444.

[0078] In this way, the first heat dissipation cover 411 can be made to communicate or not communicate with the accommodation cavity 10 by the cooperation of the first heat dissipation cover 411 and the second end plate 113. At the same time, the second heat dissipation cover 412 accommodates the fan blade 42 to accelerate the air flow inside the first heat dissipation cover 411 through the rotation of the fan blade 42, thereby improving the heat dissipation effect.

[0079] Exemplarily, the first heat dissipation cover 411 and the second heat dissipation cover 412 are communicated through an L-shaped bent pipe, which facilitates the arrangement of the first heat dissipation cover 411 and the second heat dissipation cover 412.

[0080] Moreover, setting the cover body 41 as the above structure is convenient for processing on the one hand, and on the other hand, the sizes of the first heat dissipation cover 411 and the second heat dissipation cover 412 can be flexibly set according to the installation space to save the occupied space of the motor.

[0081] Referring again to Figure 1 and Figure 2 , optionally, the rotor structure 2 further includes a rotor 22. The rotor 22 is connected to the rotating shaft 21 and is located inside the accommodation cavity 10.

[0082] Exemplarily, the rotating shaft 21 of the rotor structure 2 is installed on the housing 1 through a bearing, which avoids the wear of the housing 1 and the like.

[0083] The stator structure 3 includes a plurality of stator components 31. The plurality of stator components 31 are arranged at equal intervals with the rotating shaft 21 as the center outside the rotor structure 2. There is a gap between any two adjacent stator components 31.

[0084] In the above implementation manner, the stator component 31 is used to cooperate with the rotor 22 to achieve energy conversion. Moreover, there is a gap between the stator components 31, which can provide a flow channel for air through the gap, thereby facilitating the heat dissipation of the stator components 31.

[0085] Optionally, each set of stator assemblies 31 includes a stator mounting block 311, a stator 312, and a plurality of stator connecting rods 313. The stator mounting block 311 is connected to the stator 312, and the stator 312 is located between the rotor structure 2 and the stator mounting block 311.

[0086] The stator connecting rods 313 are arranged parallel to the rotating shaft 21. The two ends of the stator connecting rods 313 are respectively connected to the base 11, and the stator connecting rods 313 are connected to the stator mounting block 311.

[0087] In the above implementation, setting the stator structure 3 as the above structure can conveniently connect the stator 312 inside the base 11 and cooperate with the rotor structure 2 to achieve energy conversion.

[0088] Optionally, the stator assembly 31 further includes two blocking blocks 314. The two blocking blocks 314 are arranged at intervals along the length direction of the stator connecting rod 313 and are connected to the stator connecting rod 313. The stator mounting block 311 is located between the two blocking blocks 314, and the two end faces of the stator mounting block 311 are respectively in contact with the two blocking blocks 314.

[0089] In the above implementation, the blocking blocks 314 are used to limit the stator mounting block 311 to prevent the stator mounting block 311 from moving along the axis direction of the stator connecting rod 313.

[0090] Optionally, the stator assembly 31 further includes a plurality of positioning cylinders 315. The plurality of positioning cylinders 315 are arranged in one-to-one correspondence with the plurality of stator connecting rods 313. The first end of the stator connecting rod 313 is connected to the first end plate 112, the second end of the stator connecting rod 313 is slidably connected to the corresponding positioning cylinder 315, and the positioning cylinder 315 is connected to the wall of the second end plate 113.

[0091] In the above implementation, by arranging the positioning cylinders 315, when the motor is installed, the stator connecting rod 313 can be stably connected between the first end plate 112 and the second end plate 113 through the sliding fit between the positioning cylinder 315 and the stator connecting rod 313.

[0092] Exemplarily, both the stator mounting block 311 and the stator 312 are fan-shaped ring plate structural members, which can facilitate the connection between the two and at the same time enable the stator 312 to cooperate well with the rotor 22.

[0093] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
