A cooling water channel component II is provided at one end of the housing component II and extends into the interior of the housing component II. The cooling water channel component II divides the housing component II into an outer layer of the housing component II and an inner layer of the housing component II. The outer layer of the housing component II and the inner layer of the housing component II are connected by an axially arranged connecting strip II.

[0007] A water inlet is arranged on the outer layer of the shell component I on one side of the connecting strip I of the shell component I of the water channel structure of the new energy vehicle motor, and a water outlet is arranged on the outer layer of the shell component I on the other side of the connecting strip I.

[0008] A water inlet is arranged on the outer layer of the shell component II on one side of the connecting strip II of the shell component II of the water channel structure of the new energy vehicle motor, and a water outlet is arranged on the outer layer of the shell component II on the other side of the connecting strip II.

[0009] An air channel I penetrating the connecting strip I is arranged on the connecting strip I of the shell component I of the water channel structure of the new energy vehicle motor, one end of the air channel I is close to the water inlet, and the other end of the air channel I is close to the water outlet.

The outer layer of the shell component II of the shell component II of the motor shell is provided with a connecting seat II flush with the sealing surface of the shell component II, and a screw hole II is provided on the connecting seat II. The connecting bolts pass through the screw holes I and II to fix the shell components I and II.

[0015] By adopting the technical solution of the present invention, the following beneficial effects can be obtained:

[0016] The water channel structure of the motor of a new energy vehicle described in the present invention adopts a brand-new design concept to arrange the cooling water channel of the motor housing, divides the motor housing into two housing components for processing, and adopts one-piece casting processing to simplify the process.

In this way, a sealing gasket is arranged between the two housing components, and then they are buckled together and connected by connecting bolts. In this way, a cooling water channel is formed, and the cooling water channel has only one sealing gasket for sealing, unlike the method in the prior art where the motor housing and two end covers are processed separately and then connected to form a cooling water channel. Compared with the two structures, the structure of the present invention not only simplifies the processing technology of the housing component, but also reduces the sealing difficulty of the cooling water channel and improves the sealing effect, which has obvious advantages. At the same time, welding process is no longer required, so there is naturally no problem of pores in the welding part and potential safety hazards. After the motor housing and other components are assembled to form a motor, cooling water enters from the water inlet. Due to the presence of the connecting strip, the cooling water does not flow directly toward the water outlet, but flows around the cooling water channel formed by the outer layer of the housing component and the inner layer of the housing component. After a circle around the motor housing, it will flow out from the water outlet. In this way, the outer layer of the housing component and the inner layer of the housing component are reliably connected through the connecting strip, and the connecting strip has the function of isolating the cooling water, ensuring that the cooling water will flow out only after a circle. The outer layer of the housing component, the inner layer of the housing component and the connecting strip are actually cast in one piece. The water channel structure of the new energy vehicle motor described in the present invention has a simple structure. By changing the structure and processing technology, the difficulty of processing the motor housing is reduced, the process is reduced, and the cooling water channel of the motor housing is sealed with a sealing gasket at only one place, which reduces the sealing failure point, reduces the probability of water leakage failure, eliminates welding, avoids the appearance of pores, and improves the overall quality and safety of the motor.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various components involved, the function and working principle of each part, etc., through the description of the embodiments with reference to the accompanying drawings:

[0022] As attached Figure 1 -Attached Figure 2As shown, the present invention is a water channel structure of a motor of a new energy vehicle, the water channel structure of the motor of the new energy vehicle comprises a motor housing 1, the motor housing 1 comprises two housing components 2, the two housing components 2 are fixedly connected by connecting bolts, one end of each housing component 2 is provided with a cooling water channel component 3 extending into the interior of the housing component 2, the cooling water channel component 3 is provided with a U-shaped structure in cross section, the cooling water channel component 3 divides the housing component 2 into a housing component outer layer 4 and a housing component inner layer 5, the housing component outer layer 4 and the housing component inner layer 5 of each housing component 2 are connected by a connecting strip 6 arranged axially along the motor housing 1, a water inlet 7 is provided on the housing component outer layer 4 on one side of the connecting strip 6, a water outlet 8 is provided on the housing component outer layer 4 on the other side of the connecting strip 6, and the housing component 1 is provided as an integral casting structure. The above structure adopts a new design idea to arrange the cooling water channel of the motor housing, divides the motor housing into two housing components for processing, and adopts an integral casting process to simplify the process. The shell assembly processed by one-piece casting has a cooling water channel assembly extending into the shell assembly at one end, and the other end of the shell assembly is a closed structure. In this way, a sealing gasket is set between the two shell assemblies, and then they are buckled together and connected by connecting bolts. In this way, a cooling waterway (cooling water channel) is formed, and the cooling water channel has only one sealing gasket for sealing, unlike the method in the prior art where the motor housing and the two end covers are processed separately and then connected to form a cooling water channel. Compared with the two structures, the structure of the present invention not only simplifies the processing technology of the shell assembly, but also reduces the sealing difficulty of the cooling water channel and improves the sealing effect, which has obvious advantages. At the same time, welding technology is no longer required, and naturally there is no problem of pores in the welding part and safety hazards. After the motor housing and other components are assembled to form a motor, the cooling water enters from the water inlet. Due to the presence of the connecting strip, the cooling water entering will not flow directly to the water outlet, but will flow around the cooling water channel formed by the outer layer 4 of the shell assembly and the inner layer 5 of the shell assembly. After a circle around the motor housing, it will flow out from the water outlet. In this way, the outer layer 4 of the shell component and the inner layer 5 of the shell component are reliably connected through the connecting strip, and the connecting strip has the function of isolating the cooling water, ensuring that the cooling water will flow out after a circle. The outer layer 4 of the shell component, the inner layer 5 of the shell component and the connecting strip are actually cast in one piece. The water channel structure of the new energy vehicle motor described in the present invention has a simple structure. By changing the structure and processing technology, the difficulty of motor housing processing is effectively reduced, the number of processes is reduced, and the cooling water channel of the motor housing is sealed with a sealing gasket at only one place, which reduces the sealing failure point, reduces the probability of water leakage, eliminates welding, avoids the appearance of pores, and improves the overall quality and safety of the motor.

[0023] The motor housing 1 includes a housing component I9 and a housing component II10. A cooling water channel component I11 extending into the interior of the housing component I9 is ​​provided at one end of the housing component I9. The cooling water channel component I11 divides the housing component I9 into an outer layer 12 of the housing component I and an inner layer 13 of the housing component I. The outer layer 12 of the housing component I and the inner layer 13 of the housing component I are connected by an axially arranged connecting strip I. The connecting strip I plays a role of separation, so that after the cooling water enters from the water inlet 7, it is isolated by the connecting strip I, and then flows in the opposite direction of the connecting strip I until it flows in the other direction for a cycle, and then returns to the other side close to the connecting strip I, and flows out from the water outlet 8 to achieve a cycle. A cooling water channel component II15 extending into the interior of the housing component II10 is provided at one end of the housing component II10. The cooling water channel component II15 divides the housing component II10 into an outer layer 16 of the housing component II and an inner layer 17 of the housing component II. The outer layer 16 of the housing component II and the inner layer 17 of the housing component II are connected by an axially arranged connecting strip II. The connecting strip II plays a role of separation, so that after the cooling water enters from the water inlet 7, it is isolated by the connecting strip II, and then flows in the opposite direction of the connecting strip II, until it flows in the other direction for a circle, and then returns to the other side close to the connecting strip II, and flows out from the water outlet 8, completing a cycle. The shell component I9 and the shell component II10 are respectively cast in one piece, and then a sealing gasket is set, and then buckled together, and a reliable connection is achieved by bolts, and the sealing reliability is high.

[0024] The water inlet 7 is arranged on the outer layer 12 of the shell component I on one side of the connecting strip I of the shell component I9 of the water channel structure of the motor of the new energy vehicle, and the water outlet 8 is arranged on the outer layer 12 of the shell component I on the other side of the connecting strip I. In the above structure, the water inlet and the water outlet can be arranged on the shell component I9, and the water inlet and the water outlet are respectively located on both sides of the connecting strip I, so that the cooling water entering the water inlet enters the cooling water channel and flows around the motor housing under pressure, so as to achieve effective cooling coverage of the motor housing and improve the cooling efficiency.

[0025] The water inlet 7 is arranged on the outer layer 16 of the shell component II on one side of the connecting strip II of the shell component II10 of the water channel structure of the motor of the new energy vehicle, and the water outlet 8 is arranged on the outer layer 16 of the shell component II on the other side of the connecting strip II. In the above structure, the water inlet and the water outlet can also be arranged on the shell component II10, and the water inlet and the water outlet are respectively located on both sides of the connecting strip II, so that the cooling water entering the water inlet enters the cooling water channel and flows around the motor housing under pressure, so as to achieve effective cooling coverage of the motor housing and improve the cooling efficiency.

[0026] The connecting strip I of the housing component I9 of the water channel structure of the motor of the new energy vehicle is provided with an air channel I penetrating the connecting strip I, and the port at one end of the air channel I is close to the water inlet 7, and the port at the other end of the air channel I is close to the water outlet 8. The above structure, the setting of the air channel I and the selection of the arrangement position of the air channel I are because when the cooling water is cooling and circulating, the cooling water entering the cooling water channel contains gas, and the gas generates resistance to the cooling water, affecting the reliable flow and circulation of the cooling water. After the air channel I is set, after the cooling water enters the cooling water channel through the water inlet, due to the resistance of the connecting strip, the cooling water flows in the opposite direction of the connecting strip. Because the resistance in this direction is small, the cooling water flows and cools along the motor housing. The gas in the cooling water, under the action of pressure, enters the air channel I, and then directly connects to the water outlet and is discharged from the water outlet, thereby effectively removing the gas in the cooling water, and the gas will not flow along the motor housing with the cooling water, reducing the adverse effects of the gas on the cooling water and improving the cooling effect. The air channel I has a fine-pore structure, so gas can flow through it, but very little cooling water flows through it, thereby ensuring that most of the cooling water can flow around the motor housing.

[0027] The outer surface of the outer layer 12 of the shell component I of the shell component I9 of the motor housing 1 is provided with a connection seat I21 flush with the sealing surface 20 of the shell component I, and a screw hole I is provided on the connection seat I21. The outer layer 16 of the shell component II of the shell component II of the motor housing 1 is provided with a connection seat II23 flush with the sealing surface 22 of the shell component II, and a screw hole II is provided on the connection seat II23. The connecting bolt passes through the screw hole I and the screw hole II to fix the shell component I9 and the shell component II10. A sealing gasket is provided between the sealing surface 20 of the shell component I of the shell component I9 and the sealing surface 22 of the shell component II of the shell component II10. In the above structure, a plurality of connection seats I21 and a plurality of connection seats II23 are respectively provided, and a plurality of connection seats II23 are arranged with gaps along a circle of the motor housing, and a plurality of connection seats I21 are arranged with gaps along a circle of the motor housing, so that the force is evenly applied when the two shell components are connected. The provision of the sealing gasket can reliably achieve the sealing performance between the two shell components to avoid water leakage, and only one sealing gasket is required.

[0028] An air channel II penetrating the connecting strip II is arranged on the connecting strip II of the housing component II10 of the water channel structure of the motor of the new energy vehicle, and the port at one end of the air channel II is close to the water inlet 7, and the port at the other end of the air channel II is close to the water outlet 8. In the above structure, when the water inlet and the water outlet are arranged on the housing component II10, the air channel II is arranged on the connecting strip II. After the air channel II is arranged, after the cooling water enters the cooling water channel through the water inlet, due to the resistance of the connecting strip, the cooling water entering the cooling water channel flows in the opposite direction of the connecting strip, because the resistance in this direction is small, thereby realizing the normal flow of the cooling water along the motor housing, and the gas in the cooling water, under the action of pressure, enters the air channel II, and then directly connects to the water outlet and is discharged from the water outlet, thereby effectively removing the gas in the cooling water, and the gas will not flow along the motor housing with the cooling water, reducing the adverse effect of the gas on the cooling water, and improving the cooling effect. The air channel II is a pore-shaped structure, so it can be realized that the gas usually flows through, while the cooling water rarely flows through, thereby ensuring that most of the cooling water can flow along the motor housing.

[0029] In the structure of the present invention, when the water inlet and the water outlet are close to the corresponding shell assembly sealing surface, an air channel can be respectively provided on the connecting strip of each shell assembly, so that both parts are close to the water inlet, which is convenient for gas to pass through, and then the gas is directly discharged from the water outlet. Such a structure does not affect the flow of cooling water, while improving the gas discharge efficiency.

[0030] The other end of the housing assembly Ⅰ9 is provided with an end cover Ⅰ connection surface 26, and the end cover Ⅰ is fixedly connected to the end cover Ⅰ connection surface 26 through the end cover Ⅰ connection bolts. The other end of the housing assembly Ⅱ10 is provided with an end cover Ⅱ connection surface 28, and the end cover Ⅱ is fixedly connected to the end cover Ⅱ connection surface 28 through the end cover Ⅱ connection bolts. In the above structure, the cooling water channel is isolated from the end cover Ⅰ and the end cover Ⅱ, and the motor housing does not need to cooperate with the two end covers to form the cooling water channel. The two end covers are connected separately for installing related components, and there is no problem of sealing the joint between the end cover and the motor housing. In this way, only a single sealing gasket is used for water channel sealing, reducing the sealing failure point.

[0031] The water channel structure of the motor of a new energy vehicle described in the present invention adopts a brand-new design concept to arrange the cooling water channel of the motor housing, divides the motor housing into two housing components for processing, and adopts one-piece casting processing to simplify the process. The housing component processed by one-piece casting has a cooling water channel component extending into the housing component at one end, and the other end of the housing component is a closed structure. In this way, a sealing gasket is arranged between the two housing components, and then they are buckled together and connected by connecting bolts. In this way, a cooling water channel is formed, and the cooling water channel has only one sealing gasket for sealing, unlike the method in the prior art where the motor housing and two end covers are processed separately and then connected to form a cooling water channel. Compared with the two structures, the structure of the present invention not only simplifies the processing technology of the housing component, but also reduces the sealing difficulty of the cooling water channel and improves the sealing effect, which has obvious advantages. At the same time, welding process is no longer required, so there is naturally no problem of pores in the welding part and potential safety hazards. After the motor housing and other components are assembled to form a motor, cooling water enters from the water inlet. Due to the presence of the connecting strip, the cooling water does not flow directly toward the water outlet, but flows around the cooling water channel formed by the outer layer of the housing component and the inner layer of the housing component. After a circle around the motor housing, it will flow out from the water outlet. In this way, the outer layer of the housing component and the inner layer of the housing component are reliably connected through the connecting strip, and the connecting strip has the function of isolating the cooling water, ensuring that the cooling water will flow out only after a circle. The outer layer of the housing component, the inner layer of the housing component and the connecting strip are actually cast in one piece. The water channel structure of the new energy vehicle motor described in the present invention has a simple structure. By changing the structure and processing technology, the difficulty of processing the motor housing is reduced, the process is reduced, and the cooling water channel of the motor housing is sealed with a sealing gasket at only one place, which reduces the sealing failure point, reduces the probability of water leakage failure, eliminates welding, avoids the appearance of pores, and improves the overall quality and safety of the motor.

[0032] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
