Description

Technical Field

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

[0002] During high-speed rotation, the heat source of a drive motor is primarily concentrated in the windings and core of the motor's stator and rotor. Prolonged operation in a high-temperature environment can severely impact and reduce the motor's operating efficiency and service life. The efficiency limit of a drive motor is often constrained by its thermal capacity. By employing enhanced heat dissipation technology, the power density and torque density of a drive motor of the same size can be increased, thereby improving its performance and lifespan.

[0003] In related technologies, the motor stator is fixedly connected to the motor housing, and coolant circulates within the motor housing. Because the outer surface of the motor stator is in direct contact with the motor housing, the coolant flowing through the motor housing removes heat from the stator through heat exchange, providing a cooling effect. However, this cooling method has limited cooling effects and suffers from uneven cooling. Utility Model Content

[0032] Please refer to Figures 1 to 3 , Figure 1 is a structural diagram of an embodiment of a motor provided by this application, Figure 2 yes Figure 1 Schematic diagram of the assembly structure of the middle stator, the first guide ring and the second guide ring; Figure 3 yes Figure 2Schematic diagram of a local structure. In one aspect of the present application, a motor 100 is provided, which includes a housing 1, a stator 2, a first guide ring 3 and a second guide ring 4. The housing 1 is provided with a first cooling channel 11 and at least two guide holes 12 connected to the first cooling channel 11; the stator 2 is arranged in the housing 1 and fixedly connected to the housing 1; the stator 2 includes two opposite side end faces 21, and the stator 2 is provided with a second cooling channel 22 connected to the side end faces 21. The second cooling channel 22 is located inside the stator 2 to facilitate the passage of coolant and take away the heat inside the stator 2; the first guide ring 3 and the second guide ring 4 are respectively connected and fixed on the two side end faces 21. Specifically, as Figure 8 As shown, Figure 8 yes Figure 1 Schematic diagram of the structure of the first guide ring, Figure 9 yes Figure 8 Schematic diagram of a partial structure. The first guide ring 3 is provided with a first solution cavity 31 and a first through hole 32 at intervals, and the first solution cavity 31 is connected to the corresponding guide hole 12; the second guide ring 4 is provided with a second solution cavity 41 and a second through hole 42 at intervals, and the second solution cavity 41 is connected to the corresponding guide hole 12; the opposite ends of a portion of the second cooling channel 22 are connected to the first solution cavity 31 and the second through hole 42; the opposite ends of another portion of the second cooling channel 22 are connected to the second solution cavity 41 and the first through hole 32. Through the above structure, when the coolant flows through the first cooling channel 11, it can pass through the guide hole 12, the first solution cavity 31, the second cooling channel 22 in sequence, and flow out from the second through hole 42, thereby achieving cooling of the outside and inside of the stator 2 and improving the cooling effect. In addition, the coolant can also pass through the guide hole 12, the second solution chamber 41, the second cooling channel 22 in sequence and flow out from the first through hole 32. Through the two cooling circuits, the coolant can cross-flow at intervals on the inner side of the stator 2, which can improve the cooling capacity and temperature uniformity of the stator 2.

[0033] When in use, the coolant can be divided into three parts to cool the stator 2. The first part passes directly through the first cooling channel 11 and takes away the heat from the outside of the stator 2 in contact with the shell 1. The second part, when flowing through the first cooling channel 11, enters the first solution cavity 31 through the guide hole 12, and then takes away the heat from the inside of the stator 2 through the second cooling channel 22, thereby improving the cooling capacity and the cooling effect, and then flows out from the second through hole 42. The third part, when flowing through the first cooling channel 11, enters the second solution cavity 41 through another guide hole 12, and then flows out from the first through hole 32 through the second cooling channel 22. In other words, the flow directions of the second and third parts are opposite, and the cross-flow at intervals inside the stator 2 can improve the cooling capacity of the stator 2, and can also improve or avoid local overheating or overcooling, thereby improving temperature uniformity.

[0034] Furthermore, the first cooling channel 11 extends axially along the motor 100, and a guide hole 12 is formed on the inner wall of the first cooling channel 11, allowing the first portion to flow along the axial direction of the motor 100, while the second and third portions can flow out radially from the motor 100 through the guide holes 12. The two guide holes 12 are located on opposite sides of the stator 2, and the first solution cavity 31 and the second solution cavity 41 are both connected to the corresponding guide holes 12, allowing the coolant to flow from the corresponding guide holes 12 into the first solution cavity 31 or the second solution cavity 41. After the coolant flows out of the first through hole 32 or the second through hole 42, it can also cool the side end surface 21 and other structures of the stator 2, further enhancing the cooling effect.

[0035] In one embodiment of the present application, Figure 2 and Figure 3 As shown, in order to avoid the conflict of coolant with different flow directions in the second cooling channel 22, along the circumference of the motor 100, the second cooling channel 22 connecting the first solution cavity 31 and the second through hole 42 and the second cooling channel 22 connecting the second solution cavity 41 and the first through hole 32 are alternately arranged.

[0036] Specifically, the first guide ring 3 and the second guide ring 4 can be arranged in mirror-image arrangement on the two side end surfaces 21 of the stator 2 and staggered along the circumferential direction of the motor 100, so that the first solution cavity 31 corresponds to the second through hole 42, thereby realizing a cooling circuit in which the coolant passes through the first solution cavity 31, the second cooling channel 22, and the second through hole 42 in sequence; the second solution cavity 41 corresponds to the first through hole 32, so that the coolant can enter the second cooling channel 22 from the second solution cavity 41 and then flow out from the first through hole 32. Through the above structure, the coolant can cool the stator 2 along two opposite flow directions, improving the cooling capacity while also achieving uniform temperature distribution and improving or avoiding local overheating or overcooling.

[0037] Furthermore, please combine Figure 4 and Figure 5 , Figure 4 yes Figure 1 Schematic diagram of the structure of the stator. Figure 5 yes Figure 4 A plurality of second cooling channels 22 may be arranged circumferentially along the axis of the stator 2 to improve cooling uniformity.

[0038] In a specific embodiment, the second cooling channel 22 may be a circular channel, which is evenly arranged in the circumferential direction of the stator 2 and arranged in a circle along the axis of the stator 2, so that the coolant can evenly cool the circumferential direction of the stator 2 when passing through, thereby improving the temperature uniformity. Figure 6 and Figure 7 As shown, Figure 6 yes Figure 1 A schematic structural diagram of another embodiment of the stator, Figure 7 yes Figure 6 In another specific embodiment, the second cooling channel 22 may also be a channel with an opening in the shape of an elongated strip, and arranged in a circular ring along the axis of the stator 2 to improve the uniformity of cooling.

[0039] In one embodiment of this application, please continue to combine Figure 2 and Figure 4 The number of second cooling channels 22 connecting the first solution chamber 31 and the second through-hole 42 is the same as the number of second cooling channels 22 connecting the second solution chamber 41 and the first through-hole 32. This allows the coolant to evenly cool the stator 2 through two opposing cooling circuits, improving cooling efficiency. Coolant can flow from the two side end surfaces 21 of the stator 2 into the second cooling channels 22 within the stator 2, achieving uniform temperature distribution, improving or avoiding local overheating or overcooling, and thereby improving the operating efficiency and stability of the motor 100.

[0040] In one embodiment of this application, please combine Figure 2 、 Figure 8 and Figure 9 The first guide ring 3 and the second guide ring 4 each include a mounting surface 5 mounted on the corresponding side end surface 21. The first through hole 32 and the second through hole 42 both penetrate the corresponding mounting surface 5 to facilitate the flow of coolant from the second cooling channel 22. Each mounting surface 5 is provided with a plurality of spaced grooves 52. The grooves 52, together with the corresponding side end surface 21, form the first solution cavity 31 or the second solution cavity 41. Each groove 52 includes a first groove portion 521 and a second groove portion 522 that are interconnected. Specifically, the first groove portion 521 is connected to the guide hole 12. Each first through hole 32 and each second through hole 42 is located between two adjacent corresponding second groove portions 522. The second groove portion 522 is connected to the second cooling channel 22. The coolant can be guided to the second groove portion 522 through the first groove portion 521, and then flow into the second cooling channel 22 from the second groove portion 522.

[0041] Furthermore, the mounting surface 5 is further provided with a sealing protrusion 51, which divides the mounting surface 5 into a plurality of grooves 52 along the circumference of the motor 100. The sealing protrusion 51 can also enhance the sealing performance of the first solution chamber 31 and the motor 100.

[0042] Since the first through hole 32 and the second through hole 42 are both located between two adjacent corresponding second groove portions 522 , the first through hole 32 is also located between two adjacent first solution chambers 31 , and the second through hole 42 is also located between two adjacent second solution chambers 41 .

[0043] Through the above structure, when the first guide ring 3 and the second guide ring 4 are staggered along the circumference of the motor 100, the first solution cavity 31 can correspond to the second through hole 42, and the second solution cavity 41 can correspond to the first through hole 32, thereby realizing the cross flow of the coolant inside the stator 2, thereby improving the cooling efficiency and uniformity.

[0044] In one embodiment of the present application, the first groove portion is U-shaped, and the second groove portion is V-shaped; the first through hole, the second through hole and the groove are all arranged in a circle.

[0045] Specifically, the first groove portion 521 can be enclosed by the sealing protrusion 51 to form a U-shape, so that the coolant flows along the inner wall of the U into the second groove portion 522. The second groove portion 522 can also be enclosed by the sealing protrusion 51 to form a V-shape, so that the coolant is guided to the second cooling channel 22, thereby improving the flow rate and cooling efficiency.

[0046] The first and second guide rings 3 and 4 of the present embodiment have a simple structure and low manufacturing cost. Simply by providing a groove 52 on the mounting surface 5 and affixing it to the side end surface 21 of the stator 2, a solution cavity for guiding coolant into the second cooling channel 22 is formed. In one embodiment, the mounting surface 5 and the side end surface 21 can be connected by bonding to enhance the sealing of the solution cavity and improve or prevent leakage. Of course, in another embodiment, the mounting surface 5 and the side end surface 21 can also be connected by other means, such as welding.

[0047] In another embodiment of the present application, different from the above embodiment, the first guide ring 3 and the second guide ring 4 further include a circumferential surface 6 arranged on the circumference of the mounting surface 5, such as Figure 10 and Figure 11 As shown, Figure 10 yes Figure 1 A schematic structural diagram of another embodiment of the first guide ring, Figure 11 yes Figure 10 Schematic diagram of a partial structure. The first solution chamber 31 and the second solution chamber 41 both penetrate the corresponding peripheral surface 6 to form a liquid inlet 61 for connecting to the corresponding guide hole 12. The first solution chamber 31 and the second solution chamber 41 both penetrate the corresponding mounting surface 5 to form an opening 53 for connecting to the corresponding second cooling channel 22.

[0048] Specifically, the first solution chambers 31 are arranged at circumferential intervals along the mounting surface 5 within the ring body of the first guide ring 3, and are connected to the guide holes 12 through the liquid inlet 61 and to the second cooling channel 22 through the opening 53, so that the coolant can enter the first solution chamber 31 from the first cooling channel 11 through the guide holes 12 and the liquid inlet 61, and then enter the second cooling channel 22 from the opening 53, thereby achieving cooling of the interior of the stator 2.

[0049] Furthermore, to correspond to the second cooling channel 22 , the first through holes 32 and the openings 53 are arranged circumferentially and staggered to achieve cross-flow of the coolant inside the stator 2 , thereby improving cooling efficiency and temperature uniformity.

[0050] The first through holes 32 and the openings 53 are arranged in a staggered manner, that is, the first through hole 32 is located between two adjacent openings 53, which corresponds to the above structure in which the first through hole 32 is located between two adjacent first solution chambers 31. Since the structure of the second guide ring 4 is the same as that of the first guide ring 3, it will not be repeated here.

[0051] Further, if Figure 2 and Figure 4 As shown, the stator 2 further includes a winding 23 , which passes through the first through-hole 32 and the second through-hole 42 .

[0052] Specifically, the stator 2 is provided with a wire outlet hole 24 for the coil of the winding 23 to pass through. The wire outlet hole 24 is spaced apart from the second cooling channel 22 and forms a circle along the axis of the motor to facilitate the installation and cooling of the winding.

[0053] Furthermore, the first through-holes 32 are larger than the wire outlet holes 24, and each first through-hole 32 corresponds to a second cooling channel 22 and two adjacent wire outlet holes 24. This facilitates the extension of the winding 23 coils, and allows the coolant to cool the winding 23 after flowing out of the second cooling channel 22 through the first through-holes 32, further improving cooling efficiency. The second through-holes 42 are configured similarly to the first through-holes 32 and will not be further described here.

[0054] In another embodiment of the present application, please refer to Figure 12 , Figure 12 yes Figure 1 A schematic diagram of another embodiment of the first guide ring in FIG. Unlike the above embodiment, motor 100 includes either the first guide ring 3 or the second guide ring 4. For example, in the case of motor 100 including the first guide ring 3, one side end surface 21 of stator 2 is connected to the first guide ring 3 to guide coolant into the second cooling channel 22, while the other side end surface 21 serves only as coolant outlet, eliminating the need for a guide ring. Coolant flows unidirectionally within stator 2, simplifying the structure and reducing costs.

[0055] Specifically, the number of the first through holes 32 of the first guide ring 3 is the same as the outlet holes 24, and the first through holes 32 and the outlet holes 24 are arranged in a one-to-one correspondence. Since the outlet holes 24 and the second cooling channels 22, the first through holes 32 and the grooves 52 are all arranged at intervals, the grooves 52 also correspond one-to-one to the second cooling channels 22. In other words, the number of first solution cavities 31 formed by the grooves 52 and the side end face 21 of the stator 2 is the same as the number of second cooling channels 22, and they correspond one-to-one. Through the above structure, the coolant can be unidirectionally circulated through the first cooling channel 11, the guide hole 12, the first solution cavity 31, and the second cooling channel 22 in sequence, thereby simplifying the structure and reducing costs. Since the structure of the second guide ring 4 is the same as that of the first guide ring 3, the embodiment in which the motor 100 includes the second guide ring 4 has the same effect and will not be repeated here.

[0056] In another embodiment of the present application, different from the above embodiment, the first guide ring 3 further includes a circumferential surface 6 arranged on the circumference of the mounting surface 5, such as Figure 13 As shown, Figure 13 yes Figure 1 A schematic structural diagram of another embodiment of the first guide ring. The first solution cavity 31 penetrates the corresponding circumferential surface 6 to form a liquid inlet 61 for connecting to the corresponding guide hole 12. The first solution cavity 31 and the second solution cavity 41 both penetrate the corresponding mounting surface 5 to form an opening 53 for connecting to the corresponding second cooling channel 22. Through the above structure, the coolant can pass through the first cooling channel 11, the guide hole 12, the liquid inlet 61, the first solution cavity 31, the outlet 53 and the second cooling channel 22 in sequence, and then flow out from the other side end face 21 of the stator 2 to achieve one-way circulation. The design of the mounting surface 5 and the outlet 53 can improve the sealing of the first solution cavity 31, thereby improving the cooling efficiency. The second guide ring 4 has the same structure and effect, which will not be repeated here.

[0057] On the other hand, the present application further provides a vehicle, which includes the above-mentioned motor 100. Specifically, since the vehicle includes the motor 100 described in the above embodiment, it also has the beneficial effects of the above-mentioned motor 100, which will not be repeated here.
