[0040] Reference Figures 1 to 7 The diagram shows a liquid transport structure according to an embodiment of this application, wherein... Figure 2 and Figure 3 The arrows indicate the direction of transmission of the lubricating coolant. The liquid transmission structure may specifically include: a transmission pipe 10 and a suction device 20; the transmission pipe 10 includes a first end 11 and a second end 12 arranged opposite to each other, the first end 11 is provided with a first outlet 14, and the second end 12 is provided with a second outlet 16; the suction device 20 includes a pipe body and a suction port 21 for communicating with the liquid supply chamber, and the pipe body is connected to the transmission pipe 10.

[0041] In this embodiment, the lubricating coolant in the supply chamber is drawn through the suction port 21 of the suction member 20. In addition, the lubricating coolant is collected and distributed by setting the first outlet 14 and the second outlet 16 on the transmission pipe 10, thus eliminating the need for the four-way pipe design. Multiple components are integrated into the same structure, which is simple and easy to assemble. It eliminates the need for two suction members, two hydraulic pumps, two delivery pipes and a four-way pipe, greatly reducing the number of components. The relatively complex four-way pipe is eliminated, reducing the space occupied by the drive system, improving space utilization, and facilitating the spatial layout of other structures.

[0042] In this embodiment, specifically, the transmission pipe 10 is provided with a hollow transmission cavity, which is connected to the first liquid inlet 13, the first liquid outlet 14, the second liquid inlet 15, and the second liquid outlet 16, respectively, to realize the transmission of lubricating coolant. For example, the liquid transmission structure can be located close to the liquid supply cavity where the liquid storage device is located, and the liquid storage device stores lubricating coolant. For example, the lubricating coolant can be oil, which has good lubrication and cooling effects. In addition, the lubricating coolant can also be water or a mixture of oil and other substances. This embodiment does not limit the specific type of lubricating coolant.

[0043] Optionally, in this embodiment, the liquid transmission structure further includes a power connector 30. The first end 11 is also provided with a first liquid inlet 13. The power connector 30 is used to connect a first hydraulic pump 31, which is connected to the first liquid inlet 13. One end of the pipe body has a suction port 21, and the other end of the pipe body has a liquid outlet, which is connected to the power connector 30. The pipe body has a pipe, through which the suction member 20 can contain and transmit the lubricating coolant. The two ends of the pipe body have a suction port 21 and a liquid outlet, respectively. The suction port 21 is connected to the pipe and the liquid outlet of the pipe body. The suction port 21 is used to draw in the lubricating coolant, and the liquid outlet is used to connect and communicate with the power connector 30, so that the lubricating coolant drawn by the suction member 20 through the suction port 21 is transmitted from the liquid outlet to the power connector 30.

[0044] In this embodiment, the suction port 21 and the outlet are arranged opposite to each other. The suction member 20 also includes an intermediate section 22 located between the suction port 21 and the outlet. The outer wall of the intermediate section 22 is provided with a connector 23, which is connected to the outer wall of the transmission pipe 10. Lubricating coolant is transmitted through the outlet of the suction member 20, and the connection between the suction member 20 and the transmission pipe 10 is realized through the connector 23 located on the intermediate section 22 of the suction member 20, thus realizing the integrated design of the transmission pipe 10 and the suction member 20.

[0045] For example, in the embodiments of this application, the connector 23 can be a connecting plate or a connecting block, made of plastic or metal, etc. The number of connectors 23 can be one, two spaced apart, or three evenly distributed, etc. The embodiments of this application do not limit the specific type, material, setting method, and number of connectors 23.

[0046] For example, in this embodiment of the application, the power connector 30 is also configured as a pipe body, one end of which is formed with a connection port for connecting to the connection end of the suction member 20, and the other end of which is formed with a power end for connecting to the first hydraulic pump 31. The first hydraulic pump 31 can draw lubricating coolant from the power end of the power connector 30 and pump the lubricating coolant to the first inlet 13 of the transmission pipe 10.

[0047] Optionally, on the same horizontal plane, in this embodiment, the height of the first end 11 of the transmission pipe 10 is greater than the height of the second end 12. The suction port 21 is located on the side of the suction member 20 near the transmission pipe 10. Specifically, the suction port 21 is located on the side of the suction member 20 near the second end 12 of the transmission pipe 10, thereby facilitating the suction port 21 to transfer the sucked lubricating coolant to the second inlet 15 of the transmission pipe 10 via the first hydraulic pump 31. In this embodiment, the second end 12 of the suction member 20 near the transmission pipe 10 is connected to the transmission pipe 10, and the power connector 30 is connected to the first end 11 of the transmission pipe 10. The power connector 30 is used to connect the first hydraulic pump 31, and the first hydraulic pump 31 is connected to the first inlet 13. The first hydraulic pump 31 sucks the lubricating coolant through the suction member 20 and transfers the lubricating coolant from the power connector 30 to the first inlet 13. In this way, the suction element 20 and the power connector 30 are integrated on the transmission pipe 10, which facilitates the transmission of lubricating coolant to the first inlet 13 located at the higher second end 12 through the suction element 20 and the power connector 30.

[0048] In this embodiment, specifically adapted to the structural layout of the drive system, the liquid transfer structure is typically inclined, with the height of its first end 11 being greater than the height of its second end 12. This allows the lower second end 12 to be positioned closer to the reservoir containing the lubricating coolant, facilitating direct transfer of the lubricating coolant through the second inlet 15. Since the first end 11 of the liquid transfer structure is relatively high, making direct transfer of the lubricating coolant from the reservoir difficult, the suction member 20 is positioned close to the lower second end 12 to facilitate suction of the lubricating coolant. Power is then provided by the first hydraulic pump 31 to transfer the lubricating coolant to the first inlet 13 located at the first end 11 of the transfer pipe 10.

[0049] Optionally, in this embodiment, the first end 11 of the transmission pipe 10 is further provided with a first liquid inlet 13, and the liquid transmission structure also includes a first one-way valve 40. The first one-way valve 40 is disposed within the first liquid inlet 13, and the first one-way valve 40 restricts the output of lubricating coolant from the first liquid inlet 13. In this way, the flow rate of the first liquid inlet 13 is unidirectional through the first one-way valve 40, that is, the lubricating coolant can only be transmitted into the first liquid inlet 13 and cannot be output from the first liquid inlet 13, thus avoiding the risk of leakage at the first liquid inlet 13 if the flow rate within the liquid transmission structure is turbulent. Furthermore, by integrating the first one-way valve 40 within the first liquid inlet 13, there is no need to set up a separate one-way valve structure, further reducing the product weight.

[0050] And / or, the second end 12 of the transfer pipe is also provided with a second liquid inlet 15. The liquid transfer structure also includes a second check valve, which is disposed within the second liquid inlet 15. The second check valve restricts the output of lubricating coolant from the second liquid inlet 15. In this way, the flow rate of the second liquid inlet 15 is unidirectional through the second check valve, that is, the lubricating coolant can only be transferred into the second liquid inlet 15 and cannot be output from the second liquid inlet 15, thus avoiding the risk of leakage at the second liquid inlet 15 if the flow rate within the liquid transfer structure is turbulent. Furthermore, integrating the second check valve within the second liquid inlet 15 eliminates the need for a separate check valve structure, further reducing the product weight.

[0051] In this embodiment, optionally, the first one-way valve 40 includes a first valve core 41, which is a spherical valve core. Since the spherical surface provides a good sealing effect at all directions of the opening of the first inlet 13, the spherical valve core provides a good anti-leakage effect for the first inlet 13, further reducing the risk of lubricating coolant leakage from the first inlet 13.

[0052] And / or, the second check valve includes a second valve core, which is a spherical valve core. Similarly, since the spherical valve core has a good sealing effect at all directions of the opening position of the second inlet 15, it has a good anti-leakage effect on the second inlet 15, further reducing the risk of leakage of lubricating coolant from the second inlet 15.

[0053] For example, in this embodiment of the application, the lubricating coolant can be transmitted from the first inlet 13 along the transmission pipe 10 and output from the first outlet 14 and / or the second outlet 16; and / or, the lubricating coolant can be transmitted from the second inlet 15 along the transmission pipe 10 and output from the second outlet 16 and / or the first outlet 14. That is, the lubricating coolant can be output from the first outlet 14 along the first inlet 13 and from the second outlet 16 along the second inlet 15, respectively, realizing a dual-inlet and dual-outlet distribution function. In addition, the lubricating coolant can be output from the first outlet 14 and the second outlet 16 along the first inlet 13, in which case the second inlet 15 is closed, or it can be output from the first outlet 14 and the second outlet 16 along the second inlet 15, in which case the first inlet 13 is closed, thereby realizing a single-inlet and dual-outlet distribution function and enriching the flow distribution methods of the liquid transmission structure.

[0054] Optionally, in this embodiment, the inner diameters of the first outlet 14 and the second outlet 16 are different. This allows for flow distribution to the structure to be lubricated and cooled by setting different inner diameters for the first outlet 14 and the second outlet 16. For example, the inner diameter of the first outlet 14 can be larger than or smaller than the inner diameter of the second outlet 16, and can be set according to actual needs based on the heat and friction generated by the structure to be lubricated and cooled. In this embodiment, the specific values ​​of the inner diameters of the first outlet 14 and the second outlet 16 are not limited.

[0055] Optionally, in this embodiment, a first clamping part 141 is provided on both sides of the first outlet 14, and a second clamping part 161 is provided on both sides of the second outlet 16. The first clamping part 141 and the second clamping part 161 are respectively press-fitted into the housing of the drive system. In this way, a relatively stable and reliable connection is achieved between the first end 11 and the second end 12 of the transmission pipe 10 and the housing of the drive system through the first clamping part 141 and the second clamping part 161, eliminating the need for bolts and reducing product weight and installation costs.

[0056] In this embodiment, optionally, the transfer tube 10 is made of a polymer material, such as polyethylene or polyimide, which has a lighter weight, contributing to product weight reduction and lowering production costs compared to a metal four-way tube. For example, the liquid suction member 20 and the power connector 30 can also be made of polymer materials, further reducing the weight of the liquid transfer structure.

[0057] Optionally, in this embodiment, the transmission pipe 10 is manufactured using a water-assisted injection molding process, forming a first liquid inlet 13, a first liquid outlet 14, a second liquid inlet 15, and a second liquid outlet 16. This allows the transmission pipe 10 to be manufactured using a plastic part via water-assisted injection molding, enhancing its structural strength while reducing its size and weight. This method is also widely applicable, easy to implement, and simple.

[0058] In summary, the liquid transport structure of this application embodiment may include at least the following advantages:

[0059] In this embodiment, the liquid transfer structure includes a transfer pipe and a suction component. The transfer pipe includes a first end and a second end disposed opposite to each other. The first end has a first outlet, and the second end has a second outlet. The suction component includes a pipe body and a suction port for communicating with the supply chamber, and the pipe body is connected to the transfer pipe. Thus, the lubricating coolant in the supply chamber is drawn through the suction port of the suction component, and the pipe body is connected to the transfer pipe, achieving an integrated design of the transfer pipe and the suction component. Furthermore, by providing a first outlet and a second outlet on the transfer pipe, the convergence and distribution of the lubricating coolant are achieved, eliminating the need for a four-way pipe design. Multiple components are integrated into a single structure, resulting in a simple structure and convenient assembly. It eliminates the need for two suction components, two hydraulic pumps, two delivery pipes, and a four-way pipe, significantly reducing the number of components and eliminating the relatively complex four-way pipe, thus reducing the space required for the drive system, improving space utilization, and facilitating the spatial layout of other structures. Moreover, the lubricating coolant can be output from both the first and second outlets, achieving a dual-inlet, dual-outlet distribution function.

[0060] This application also proposes a lubrication and cooling device, which includes a liquid transport structure for collecting and distributing the lubricating coolant.

[0061] Optionally, in the embodiments of this application, such as Figure 2 and Figure 3 As shown, the lubrication and cooling device also includes a first hydraulic pump 31 and a second hydraulic pump 50. The first hydraulic pump 31 is connected to the power connector 30 of the liquid transmission structure and the first inlet 13, respectively, and the second hydraulic pump 50 is connected to the second inlet 15 of the liquid transmission structure. The first hydraulic pump 31 provides a relatively stable and reliable driving force for transmitting lubricating and cooling fluid to the first inlet 13, and the second hydraulic pump 50 provides a relatively stable and reliable driving force for transmitting lubricating and cooling fluid to the second inlet 15.

[0062] In this embodiment, the second hydraulic pump 50 is positioned lower than the first hydraulic pump 31. For example, at least a portion of the second hydraulic pump 50 can be immersed in the lubricating coolant in the reservoir, and the second hydraulic pump 50 can directly transfer the lubricating coolant in the reservoir to the second inlet 15.

[0063] In summary, the lubrication and cooling device of this application embodiment may include at least the following advantages:

[0064] In this embodiment, the lubrication and cooling device includes a liquid transmission structure comprising a transmission pipe and a suction component. The transmission pipe includes a first end and a second end disposed opposite to each other, the first end having a first outlet and the second end having a second outlet. The suction component includes a pipe body and a suction port for communicating with the supply chamber, the pipe body being connected to the transmission pipe. Thus, the lubricating coolant in the supply chamber is drawn through the suction port of the suction component, and the pipe body is connected to the transmission pipe, achieving an integrated design of the transmission pipe and the suction component. Furthermore, by providing a first outlet and a second outlet on the transmission pipe respectively, the convergence and distribution of the lubricating coolant are achieved, eliminating the need for a four-way pipe design. Multiple components are integrated into a single structure, resulting in a simple structure and convenient assembly. It eliminates the need for two suction components, two hydraulic pumps, two delivery pipes, and a four-way pipe, significantly reducing the number of components, eliminating the relatively complex four-way pipe, reducing the space required for the drive system, improving space utilization, and facilitating the spatial layout of other structures. Furthermore, the lubricating coolant can be output from the first outlet and the second outlet respectively, realizing a dual-inlet and dual-outlet distribution function.

[0065] This application provides a drive system comprising a housing and a lubrication and cooling device, or a liquid transfer structure, disposed within the housing. Specifically, the housing has a first pressing platform and a second pressing platform spaced apart. The first pressing part 141 of the first outlet 14 of the liquid transfer structure is interference-fitted with the first pressing platform, and the second pressing part 161 of the second outlet 16 of the liquid transfer structure is interference-fitted with the second pressing platform. Thus, a relatively tight interference fit is achieved between the housing and the first pressing part 141 via the first pressing platform, and a relatively tight interference fit is achieved between the housing and the second pressing part 161 via the second pressing platform.

[0066] For example, in this embodiment, the housing may include a first outer shell and a second outer shell. The first outer shell is pressed onto one side of the first pressing part 141 and the second pressing part 161, respectively, and the second outer shell is pressed onto the other side of the first pressing part 141 and the second pressing part 161, that is, the first outer shell and the second outer shell are respectively disposed on both sides of the liquid transmission structure. The first pressing platform and the second pressing platform may be disposed on the first outer shell, or on the second outer shell, or both the first pressing platform and the second pressing platform may be disposed on the first outer shell and the second outer shell. This embodiment does not limit this, thereby achieving a relatively tight interference fit between the liquid transmission structure and the housing of the drive system.
