[0036] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0037] Reference below Figure 1-Figure 5 The controller 100 according to the embodiment of the present invention can avoid the need for additional refrigerant flow channels in the housing and can also flexibly arrange the refrigerant flow channels 21 , thereby improving the production efficiency of the controller 100 .

[0038] Combination Figure 1-Figure 5 As shown, the controller 100 according to the first embodiment of the utility model includes a housing 10, a drive module 20 and a connecting hose 30. The housing 10 constitutes the main external structural outline of the controller 100, which can protect the internal related structures; the drive module 20 is mainly used to provide accurate control signals for electronic switch devices to ensure that the components can work in an expected manner; the connecting hose 30 can provide a designated delivery channel for the refrigerant.

[0039] Specifically, a accommodating cavity 11 is formed inside the shell 10, a first interface 12 for external connection is provided on the outer wall of the shell 10, the driving module 20 is arranged in the accommodating cavity 11, a refrigerant flow channel 21 is formed inside the driving module 20, and the connecting hose 30 is respectively connected to the first interface 12 and the refrigerant flow channel 21 to allow the refrigerant to flow between the refrigerant flow channel 21 and the first interface 12.

[0040] Specifically, the drive module 20 is located in the accommodating cavity 11 of the shell 10, so that an installation space can be provided for the drive module 20, and a structural protection effect can be formed for the drive module 20; the refrigerant flow channel 21 can provide a flow channel for the refrigerant, so that the refrigerant can continuously exchange heat with the drive module 20, thereby improving the heat dissipation effect of the drive module 20 during operation; the first interface 12 of the outer wall of the shell 10 can be connected to an external structure (such as a pipe), and the connecting hose 30 is connected between the first interface 12 and the refrigerant flow channel 21, so that the refrigerant can exchange and flow inside and outside the shell 10 through the connecting hose 30, thereby ensuring the heat dissipation effect of the drive module 20.

[0041] Compared with the traditional structure of arranging the refrigerant flow channel in the shell, the embodiment in the present case adopts the structure of separately arranging the refrigerant flow channel 21 connected to the outside of the shell 10 in the driving module 20, so as to avoid the need to additionally arrange the refrigerant flow channel in the shell, thereby reducing the processing complexity of the shell 10; and compared with the rigid pipe, since the connecting hose 30 is more flexible, it can be easily bent and turned in a narrow or complex space, so that it is convenient for it to flexibly change its own shape to adapt to the position of the outlet of the refrigerant flow channel 21 and the first interface 12, thereby improving the flexibility and freedom of arranging the refrigerant flow channel 21 in the driving module 20, which is conducive to realizing the design effect of simplifying the structure of the refrigerant flow channel 21 of the controller 100 and miniaturizing the controller 100.

[0042] Therefore, by setting up the controller 100, it is possible to avoid setting up an additional refrigerant flow channel in the shell, thereby reducing processing complexity, and the refrigerant flow channel 21 can be flexibly arranged, thereby reducing design difficulty and further improving the production efficiency of the controller 100.

[0043] According to some optional embodiments of the present invention, combined with Figure 1-Figure 5 As shown, the first end 31 of the connecting hose 30 is inserted into the first interface 12, which can ensure the smooth transmission of the refrigerant in the pipeline, avoid pressure loss or unstable flow rate caused by loose connection, and the plug-in connection usually does not require complex tools or professional skills, is easy to operate, can quickly complete the installation, and save time and labor costs. In addition, compared with threaded connection or other complex connection methods, the plug-in connection can reduce the need for additional accessories, thereby simplifying the overall structure.

[0044] Specifically, combined Figure 3 and Figure 5 As shown, the first end 31 of the connecting hose 30 is interference-fitted with the first interface 12. The interference fit can generate sufficient friction between the connecting hose 30 and the first interface 12 by causing a certain amount of interference due to the size difference between the connecting hose 30 and the first interface 12, thereby preventing the risk of the connecting hose 30 accidentally falling off or loosening during operation; and can also ensure the smooth transmission of the refrigerant in the connecting hose 30, avoiding pressure loss or unstable flow rate due to loose connection.

[0045] Moreover, compared with the traditional structure of adding additional seals (such as O-rings) or clamps to the outer periphery of the hard connecting pipe, the embodiment of the present case can also achieve close contact between the connecting hose 30 and the first interface 12, thereby achieving the effect of self-sealing of the connecting hose 30 (that is, the connecting hose 30 itself can be used as an elastic deformation sealing medium to form a seal with the first interface 12 of the shell 10) at the first interface 12, without the need for additional seals, reducing the number of parts, and facilitating the simplification of the production and assembly process and optimizing costs.

[0046] Furthermore, combined with Figure 3 and Figure 5 As shown, the first end 31 of the connecting hose 30 is provided with a first limiting portion 311, and the first interface 12 is provided with a second limiting portion. The first limiting portion 311 is located on the side of the second limiting portion away from the accommodating cavity 11, and the first limiting portion 311 cooperates with the second limiting portion in the length direction of the first interface 12.

[0047] It can be understood that the first limiting portion 311 and the second limiting portion cooperate with each other in the length direction of the first interface 12, so that the first interface 12 can form a limiting effect on the connecting hose 30 in the length direction of the first interface 12, thereby ensuring the position stability of the connecting hose 30 and preventing the connecting hose 30 from unexpectedly moving in the length direction of the first interface 12.

[0048] Specifically, combined Figure 3 and Figure 5 As shown, the connecting hose 30 includes a first pipe segment 32 and a second pipe segment 33, the outer diameter of the first pipe segment 32 is smaller than the outer diameter of the second pipe segment 33, the first pipe segment 32 is inserted into the first interface 12, and the first pipe segment 32 is provided with a first end 31, the second pipe segment 33 is integrally formed with the first pipe segment 32, and the second pipe segment 33 is connected to the refrigerant flow channel 21.

[0049] That is to say, the first pipe section 32 of the connecting hose 30 is inserted into the first interface 12, and the second pipe section 33 of the connecting hose 30 establishes a connection relationship with the refrigerant flow channel 21, so that the refrigerant can smoothly achieve the effect of flow exchange inside and outside the shell 10 through the connecting hose 30.

[0050] Among them, since the outer diameter of the second pipe section 33 is larger than the outer diameter of the first pipe section 32, after the first pipe section 32 is inserted into the first interface 12, the second pipe section 33 can effectively limit and block the first interface 12, thereby preventing the risk of accidental loosening or falling off of the connecting hose 30 and ensuring the position stability of the connecting hose 30.

[0051] In addition, the second pipe section 33 and the first pipe section 32 adopt an integrally molded structure, which can reduce the number of parts and assembly time, thereby reducing the assembly process, reducing manufacturing costs, and improving production efficiency; it can also avoid the matching errors that may occur in traditional multi-piece assembly, thereby improving the accuracy and consistency of the product; it can also reduce stress concentration points (due to the absence of seams and welds), thereby improving the overall structural strength and rigidity of the connecting hose 30, and then improving the structural reliability of the connecting hose 30.

[0052] According to some optional embodiments of the present invention, combined with Figure 3 and Figure 5 As shown, the refrigerant flow channel 21 is provided with a second interface, and the second end 34 of the connecting hose 30 is sleeved on the second interface. Such an arrangement can form an inserted connection between the second interface and the connecting hose 30. This connection method can ensure the smooth transmission of the refrigerant in the pipeline, avoid pressure loss or unstable flow rate due to loose connection, and the inserted connection usually does not require complicated tools or professional skills, is easy to operate, and can be quickly installed, saving time and labor costs; it can also form a close contact between the second interface and the connecting hose 30, thereby ensuring the sealing of the connection between the two and preventing refrigerant leakage.

[0053] In addition, compared with threaded connections or other complex connection methods, plug-in connections can reduce the need for additional accessories, thereby simplifying the overall structure.

[0054] Specifically, the second end 34 of the connecting hose 30 is interference-fitted with the second interface. The interference fit can generate sufficient friction between the connecting hose 30 and the second interface by causing a certain amount of interference due to the size difference between the connecting hose 30 and the second interface, thereby preventing the risk of the connecting hose 30 accidentally falling off or loosening during operation; it can also generate close contact between the connecting hose 30 and the second interface, thereby achieving the effect of the connecting hose 30 self-sealing at the second interface, preventing refrigerant leakage, and no additional seal is required, thereby reducing the number of parts; it can also ensure the smooth transmission of the refrigerant in the connecting hose 30, avoiding pressure loss or unstable flow rate caused by loose connection.

[0055] Furthermore, a third limiting portion is provided on the outer periphery of the second interface, and the third limiting portion cooperates with the second end 34 of the connecting hose 30 to limit the length direction of the second interface.

[0056] It can be understood that the third limiting portion and the second end 34 of the connecting hose 30 limit each other in the length direction of the second interface, so that the second interface can form a limiting effect on the connecting hose 30 in the length direction of the second interface, thereby ensuring the position stability of the connecting hose 30 and preventing the connecting hose 30 from unexpectedly moving in the length direction of the second interface.

[0057] Specifically, combined Figure 3 and Figure 5 As shown, a guide opening 341 is formed on the inner wall of the second end 34 of the connecting hose 30, and the cross-sectional area of ​​the guide opening 341 gradually decreases in the direction away from the second interface. This makes it easier for the second interface to find the second end 34 of the connecting hose 30, align the installation position, and ensure the correct direction, thereby providing a guide for the installation process between the connecting hose 30 and the second connector, thereby improving assembly efficiency.

[0058] According to some optional embodiments of the present invention, combined with Figure 1 , Figure 2 and Figure 4 As shown, there are two first interfaces 12 and two connecting hoses 30 , and second interfaces are respectively provided at both ends of the refrigerant flow channel 21 . The two first interfaces 12 and the two second interfaces correspond one to one and are respectively connected through corresponding connecting hoses 30 .

[0059] Optionally, the above arrangement can form a refrigerant circulation loop at both ends of the refrigerant flow channel 21 to facilitate the refrigerant to continuously perform heat exchange work on the driving module 20, thereby improving the heat exchange efficiency of the driving module 20.

[0060] Alternatively, the above arrangement can increase the number of flow paths for the refrigerant to enter and exit the refrigerant channel 21 , thereby increasing the heat exchange rate and heat exchange area of ​​the refrigerant in the same time, and improving the heat exchange effect of the drive module 20 .

[0061] Combination Figure 1-Figure 3 As shown, the driving assembly according to the second embodiment of the utility model includes a refrigerant pipe 200 and the controller 100 of the above embodiment, and the refrigerant pipe 200 is connected to the first interface 12. The refrigerant pipe 200 can transport the external refrigerant to the first interface 12 and then flow into the refrigerant flow channel 21, and can also facilitate the refrigerant inside the refrigerant flow channel 21 to flow into the refrigerant pipe 200 after passing through the first interface 12, so as to facilitate the refrigerant to form a circulating flow heat exchange effect on the driving module 20.

[0062] Specifically, combined Figure 2-Figure 4 As shown, a connector 201 and an elastic clamping member 202 are provided at one end of the refrigerant tube 200, the elastic clamping member 202 is sleeved on one of the connector 201 and the first interface 12, and the elastic clamping member 202 is engaged with the connector 201 and the other of the first interface 12. The refrigerant tube 200 can be connected to the connector 201 by thermoplastic connection or clamp connection, etc., but is not limited thereto.

[0063] For example, after the connector 201 is sleeved and connected to the first interface 12, the elastic clamping member 202 is sleeved on the connector 201, and the elastic clamping member 202 is engaged with the first interface 12, so that on the basis of forming a plug-in connection between the connector 201 and the first interface 12, the elastic clamping member 202 can further increase the frictional fastening force between the connector 201 and the first interface 12, thereby preventing the risk of accidental loosening or falling off between the connector 201 and the first interface 12, thereby improving the connection firmness between the two. Moreover, since the elastic clamping member 202 has a simple structure, reliable connection, and quick and convenient disassembly and installation functions, it can effectively reduce the time and cost required for maintenance, replacement, disassembly and assembly.

[0064] Furthermore, combined with Figure 2-Figure 4 As shown, one of the connector 201 and the first interface 12 is provided with a mounting groove 203 , and the other of the connector 201 and the first interface 12 is provided with a snap-fitting groove 204 , the elastic clamping member 202 is provided in the mounting groove 203 , and the elastic clamping member 202 is snap-fitted with the snap-fitting groove 204 .

[0065] For example, the connector 201 is provided with an installation groove 203 along at least part of its circumference, and the first connector is provided with a snap-fit ​​groove 204 along at least part of its circumference. In the process of sleeve-installing the connector 201 on the first interface 12, the installation groove 203 of the connector 201 and the first interface 12 are first aligned in the axial direction of the first interface 12, and then the elastic clamping member 202 is elastically deformed radially inward along the first interface 12 to extend into the snap-fit ​​groove 204 of the first interface 12. At this time, the elastic clamping member 202 establishes a snap-fitting relationship with the snap-fit ​​groove 204, which can further enhance the connection firmness between the connector 201 and the first interface 12, thereby improving the flow smoothness of the refrigerant between the refrigerant pipe 200 and the controller 100.

[0066] Moreover, when the refrigerant pipe 200 needs to be replaced or repaired, the elastic clamping member 202 only needs to overcome the elastic force under the action of external force to release the clamping fit between the elastic clamping member 202 and the clamping groove 204, thereby facilitating subsequent disassembly and assembly work, thereby improving the convenience of disassembly and assembly (that is, the refrigerant pipe 200 and the controller 100 can be quickly combined and separated).

[0067] Optionally, the assembly process of the refrigerant pipe 200 and the controller 100 is introduced below: after the drive module 20 and the connecting hose 30 are assembled, the connector 201 is connected to the first interface 12, and then the elastic clamping piece 202 is installed to complete the connection between the refrigerant flow channel 21 inside the drive module 20 and the external refrigerant pipe 200.

[0068] Specifically, a connector 201 is provided at one end of the refrigerant pipe 200, the first interface 12 is provided with one of a hook and a slot, and the connector 201 is provided with the other of a hook and a slot, and the hook and the slot are snap-fitted.

[0069] For example, the first interface 12 is provided with a hook, and the connecting head 201 is provided with a slot, and the hook and the slot are snap-fitted together, so that the refrigerant pipe 200 can be connected as a whole through the connecting head 201 and the first interface 12 on the shell 10, thereby ensuring that the refrigerant can smoothly achieve the flow exchange effect between the refrigerant pipe 200 and the refrigerant flow channel 21; and compared with other connection methods (such as screw connection, bonding, etc.), the snap connection does not require additional parts to connect the connecting head 201 and the first interface 12 as a whole, avoiding additional unnecessary material consumption; it can also provide sufficient holding force to ensure that the connecting head 201 will not loosen or fall off during use.

[0070] Moreover, the snap-on connection structure is simple, the connection is reliable, and it has the functions of quick and convenient disassembly and installation (that is, it can realize the rapid connection and separation of the refrigerant pipe 200 and the controller 100), which can effectively reduce the time and cost required for maintenance and replacement.

[0071] The vehicle according to the embodiment of the third aspect of the utility model includes the drive assembly of the above-mentioned embodiment. A vehicle having such a drive assembly does not need to set a refrigerant flow channel on the shell of the controller 100, thereby reducing the processing complexity of the shell 10. The position of the refrigerant flow channel 21 in the controller 100 can also be flexibly designed to improve the design freedom. The number of parts required for sealing can also be reduced, reducing production costs, thereby improving the market competitiveness of the vehicle.
