Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a multi-way valve integrated device, a vehicle thermal management system, and a vehicle. Background Technology

[0002] Multi-port valves are an important component of vehicle thermal management systems, primarily used to regulate and control the flow direction of refrigerant or coolant. Multi-port valves, such as nine-port valves, are used in hybrid, pure electric, and traditional gasoline vehicles, with nine-port valves being particularly prevalent in hybrid vehicles. This is because hybrid vehicles typically need to simultaneously manage the thermal management needs of the engine, electric motor, air conditioning, and battery systems, requiring effective regulation of coolant flow to achieve optimal thermal efficiency and power performance. In the process of multi-port valves, such as nine-port valves, participating in vehicle thermal management, they usually need to work in conjunction with modules such as heat exchangers. However, in related technologies, the various components involved in thermal management, such as multi-port valves and heat exchangers, are located in various positions within the vehicle, requiring extensive piping connections, occupying considerable space, affecting the layout of other modules in the thermal management system, and increasing costs. Utility Model Content

[0003] This utility model aims to solve at least one of the above-mentioned technical problems.

[0004] To address the aforementioned problems, this utility model provides a multi-port valve integrated device, comprising a multi-port valve, a heat exchanger, and a flow channel plate. The flow channel plate has flow channel a and flow channel b internally, and at least one side of the flow channel plate has an external pipeline interface. The multi-port valve and the heat exchanger are located on the same side of the flow channel plate where the external pipeline interface is not located. The two valve ports of the multi-port valve are connected to the two heat exchange ports of the heat exchanger through the corresponding flow channel a, and the other valve ports of the multi-port valve are connected to the external pipeline interface through the corresponding flow channel b.

[0005] This utility model provides a multi-way valve integrated device. When applied to a vehicle thermal management system, the multi-way valve and heat exchanger are integrated together via a flow channel plate. Specifically, both the multi-way valve and heat exchanger are located on the same side of the flow channel plate, thus improving the integration between them. This results in a more compact structure, reducing the space occupied in the vehicle's engine compartment and lowering costs. One of the two heat exchange ports of the heat exchanger can be an inlet, and the other an outlet. For example, when the heat load (or cold load) from other components in the vehicle's thermal management system enters the multi-way valve through an external pipeline interface and a flow channel b, it can then enter the heat exchanger through a flow channel a and the heat exchanger's inlet for heat exchange. The heat then flows out of the heat exchanger through its outlet, and after passing through another flow channel a, the multi-way valve, and another flow channel b, it flows out through another external pipeline interface, achieving heat exchange with external heat loads (or cold loads) and improving thermal management efficiency.

[0006] Furthermore, the flow channel plate has a first plate side and a second plate side arranged sequentially along its thickness direction. The first plate side of the flow channel plate is provided with the external pipeline interface, and the multi-way valve and the heat exchanger are both located on the second plate side of the flow channel plate where the external pipeline is not provided.

[0007] Furthermore, the heat exchanger and the multi-way valve are arranged sequentially along a first predetermined direction of the flow channel plate, wherein the first predetermined direction is a direction perpendicular to the thickness direction of the flow channel plate;

[0008] The flow channel plate is provided with an extension arm protruding from it. The end of the extension arm is provided with a mounting hole. The axial direction of the mounting hole is parallel to a second predetermined direction of the flow channel plate, wherein the second predetermined direction is perpendicular to both the first predetermined direction and the thickness direction of the flow channel plate.

[0009] This utility model also provides a vehicle thermal management system, including the multi-way valve integrated device as described above.

[0010] Since the technical improvements and effects of the vehicle thermal management system are the same as those of the multi-way valve integration device, the vehicle thermal management system will not be described in detail again.

[0011] This utility model also provides a vehicle, including the multi-way valve integrated device or vehicle thermal management system as described above.

[0012] Since the technical improvements and effects of the vehicle are the same as those of the multi-way valve integrated device or the vehicle thermal management system, the vehicle will not be described in detail again.

[0013] Furthermore, the vehicle also includes an engine mount and a nacelle longitudinal beam, the engine mount being disposed on the upper side of the nacelle longitudinal beam, and the multi-way valve integration device being located above the engine mount and fixed relative to the nacelle longitudinal beam.

[0014] Furthermore, the vehicle also includes a cabin side beam, which is an arc-shaped structure protruding outwards from the vehicle. In the longitudinal direction of the vehicle, the multi-way valve integration device and the engine mount are located behind the front end of the cabin side beam.

[0015] Furthermore, the first setting direction of the multi-way valve integrated device is set at an angle to the longitudinal direction of the vehicle, and the rear end of the multi-way valve integrated device is inclined toward the engine compartment side beam. The second setting direction of the multi-way valve integrated device is parallel to the vertical direction of the vehicle, and the second plate side of the flow channel plate of the multi-way valve integrated device is toward the engine compartment side beam.

[0016] Furthermore, the vehicle also includes a side beam connecting plate, wherein at least a portion of the lower side of the cabin side beam in its extending direction is connected to the cabin longitudinal beam via the side beam connecting plate.

[0017] Furthermore, the multi-way valve integration device is connected to the nacelle longitudinal beam and / or the side beam connecting plate via an extension arm; and / or, the vehicle also includes a nacelle tower package located behind the flow channel plate of the multi-way valve integration device, the multi-way valve integration device being connected to the nacelle tower package via an extension arm.

[0031] See Figure 1-3A multi-port valve integrated device 1 according to an embodiment of the present invention includes a multi-port valve 11, a heat exchanger 12, and a flow channel plate 13. The flow channel plate 13 is provided with a flow channel a (not shown in the figure) and a flow channel b (not shown in the figure). At least one side of the flow channel plate 13 is provided with an external pipeline interface 131. The multi-port valve 11 and the heat exchanger 12 are located on the same side of the flow channel plate 13 where the external pipeline interface 131 is not provided. The two valve ports of the multi-port valve 11 are connected to the two heat exchange ports of the heat exchanger 12 through the corresponding flow channel a, and the other valve ports of the multi-port valve 11 are connected to the external pipeline interface 131 through the corresponding flow channel b.

[0032] Among them, the other valve ports of the multi-way valve 11 refer to the valve ports that are not connected to the heat exchange ports of the heat exchanger 12. The external pipeline interface 131 can be a hollow tube column structure with the flow channel plate 13 protruding outward, so as to facilitate docking with the external pipeline, and then connect with other components or modules in the vehicle thermal management system through the external pipeline, so that the multi-way valve integrated device 1 can participate in the entire vehicle thermal management system.

[0033] The phrase “the two valve ports of the multi-way valve 11 (denoted as the first valve port and the second valve port) are connected to the two heat exchange ports of the heat exchanger 12 in a one-to-one correspondence through the corresponding flow channel a” means that the first valve port of the multi-way valve 11 is connected to one heat exchange port of the heat exchanger 12 through one flow channel a, and the second valve port of the multi-way valve 11 is connected to the other heat exchange port of the heat exchanger 12 through another flow channel a.

[0034] "The other valve ports of the multi-way valve 11 are connected to the external pipeline interface 131 through the corresponding flow channel b" means that any one of the other valve ports of the multi-way valve 11, such as the third valve port, is connected to at least one external pipeline interface 131 through a flow channel b. When the third valve port is connected to one external pipeline interface 131 through a flow channel b, the third valve port can only connect to one external pipeline through this one external pipeline interface 131; when the third valve port is simultaneously connected to, for example, two external pipeline interfaces 131 through a flow channel b, the third valve port can connect to two external pipelines through the two external pipeline interfaces 131. At this time, the third valve port and the corresponding two external pipeline interfaces 131 constitute a "three-way valve", making the multi-way valve integrated device 1 more flexible and functional when applied in vehicle thermal management.

[0035] In this embodiment, one of the two heat exchange ports of the heat exchanger 12 can be an inlet and the other an outlet. Thus, for example, when the heat load (or cold load) of other components in the vehicle's thermal management system enters the multi-way valve 11 through an external pipeline interface 131 and a flow channel b, it can then enter a flow channel a through the multi-way valve 11, and through this flow channel a and the inlet of the heat exchanger 12 for heat exchange. Afterward, it flows out of the heat exchanger 12 through its outlet, and sequentially through another flow channel a, the multi-way valve 11, and another flow channel b before exiting through another external pipeline interface 131. This achieves heat exchange with the external heat load (or cold load), improving thermal management efficiency. The heat load (or cold load) can be the cooling water of the water-cooling system or the coolant of the air conditioning system 6.

[0036] In this embodiment, the multi-way valve 11 can be a nine-way valve, similar to related technologies. A nine-way valve is an important component in a vehicle thermal management system, used to regulate and control the flow direction of refrigerant or coolant. It is understood that in this embodiment, two valve ports of the nine-way valve are connected one-to-one with the two heat exchange ports of the heat exchanger 12 via corresponding flow channels a. Any one of the other seven valve ports of the nine-way valve is connected to at least one external pipeline interface 131 via a corresponding flow channel b, so that it can be connected to components or modules outside the multi-way valve integration device 1 via pipelines through the flow channel plate 13 (specifically, the external pipeline interface 131 outside the flow channel plate 13).

[0037] This embodiment provides a multi-way valve integrated device 1, which, when applied in a vehicle thermal management system, integrates the multi-way valve 11 and the heat exchanger 12 via a flow channel plate 13. In particular, since both the multi-way valve 11 and the heat exchanger 12 are located on the same side of the flow channel plate 13, the integration between the multi-way valve 11 and the flow channel plate 13 is improved, resulting in a more compact structure, reduced space occupation in the vehicle's engine compartment, and lower costs. Furthermore, the multi-way valve 11 and the heat exchanger 12 are located on the side of the flow channel plate 13 without an external pipeline interface 131. This ensures that when an external pipeline is installed at the external pipeline interface 131, the external pipeline does not need to avoid the multi-way valve 11 and the heat exchanger 12, guaranteeing the feasibility and convenience of pipeline layout. Moreover, the multi-way valve 11 and the heat exchanger 12 are located on the side of the flow channel plate 13 that does not have an external pipeline interface 131, ensuring that the flow channel plate 13 does not become too large due to the simultaneous arrangement of the heat exchanger 12, the multi-way valve 11 and the external pipeline interface 131 on one side, which can further reduce the space occupation.

[0038] Furthermore, since the other valve ports of the multi-way valve 11 are connected to the external pipeline interface 131 through the corresponding flow channels b, that is, there are flow channels b between the other valve ports of the multi-way valve 11 and the corresponding external pipeline interface 131, the shape, extension direction and length of each flow channel b can be designed in the flow channel plate 13, so that the multiple external pipeline interfaces 131 are not too concentrated on the flow channel plate 13, thereby ensuring that the connection between the multiple external pipelines and the corresponding external pipeline interface 131 is not too concentrated, which facilitates pipeline layout.

[0039] In addition, since the multi-way valve integrated device 1 occupies less space and has a compact structure, it is particularly suitable for application in the thermal management system of hybrid vehicles with multiple components or modules, which is more conducive to improving the thermal management efficiency of hybrid vehicles.

[0040] When the multi-way valve 11 is a nine-way valve, the multi-way valve integrated device 1 can also be called a nine-way valve integrated device. Of course, in other embodiments, the multi-way valve 11 can also be a seven-way valve, an eight-way valve, or even a ten-way valve, etc.

[0041] See Figure 1-3 Optionally, the flow channel plate 13 has a first plate side 13a and a second plate side 13b arranged sequentially along its thickness direction. The first plate side 13a of the flow channel plate 13 is provided with the external pipe interface 131, and the multi-way valve 11 and the heat exchanger 12 are both located on the second plate side 13b of the flow channel plate 13 where the external pipe interface 131 is not provided.

[0042] And / or, the flow channel plate 13 has a third plate side 13c and a fourth plate side 13d arranged sequentially along its first predetermined direction, and the third plate side 13c and / or the fourth plate side 13d of the flow channel plate 13 are provided with the external pipe interface 131, wherein the first predetermined direction is a direction perpendicular to the thickness direction of the flow channel plate 13.

[0043] In this embodiment, as Figure 1-3 As shown, the thickness direction of the flow channel plate 13 is parallel to the s3 direction in the figure. The first plate side 13a of the flow channel plate 13 is provided with an external pipeline interface 131, while the multi-way valve 11 and the heat exchanger 12 are both located on the second plate side 13b of the flow channel plate 13, which is not provided with an external pipeline interface 131. In this way, the multi-way valve integrated device 1 can be connected to external components or modules through the external pipeline interface 131 of the first plate side 13a via pipelines. When the pipeline is arranged, there will be no interference with the multi-way valve 11 and the heat exchanger 12 on the second plate side 13b, making it easier for it to participate in the layout of the entire vehicle thermal management system in the engine compartment.

[0044] In this embodiment, as Figure 1-3As shown, the first set direction of the flow channel plate 13 is parallel to the s1 direction in the figure. The two sides of the flow channel plate 13 arranged sequentially along the first set direction are the third plate side 13c and the fourth plate side 13d, respectively. In addition to the aforementioned first plate side 13a, which can be provided with an external pipeline interface 131, the third plate side 13c and / or the fourth plate side 13d can also be provided with an external pipeline interface 131. This allows the multi-way valve integrated device 1 to be connected to external components or modules through pipelines at multiple locations. When applied to the vehicle thermal management system, it will be more flexible and reduce the bending and wiring of the external pipeline.

[0045] See Figure 1-3 Optionally, the flow channel plate 13 is provided with an extension arm 14 protruding outwards.

[0046] In this embodiment, the flow channel plate 13 is provided with a protruding extension arm 14, and the end of the extension arm 14 may be provided with a mounting hole 141. Thus, when the multi-way valve integrated device 1 is installed in the engine compartment, it can be bolted to the vehicle body through the mounting hole 141 at the end of the extension arm 14, making installation and subsequent disassembly very convenient. The extension arm 14 may have a certain extension length, allowing the flow channel plate 13, the multi-way valve 11, and the heat exchanger 12 to be positioned at a suitable height within the engine compartment. In other embodiments, the extension arm 14 may be fixed to the engine compartment by welding or snap-fitting.

[0047] Optionally, multiple extension arms 14 can be provided, with multiple extension arms 14 located on different sides of the flow channel plate 13. The extension arms 14 on these different sides are connected to the vehicle body, which can ensure the stability of the multi-way valve integration device 1 after installation.

[0048] See Figure 1-3 Optionally, the heat exchanger 12 and the multi-way valve 11 are arranged sequentially along the first predetermined direction of the flow channel plate 13, wherein the first predetermined direction is a direction perpendicular to the thickness direction of the flow channel plate 13;

[0049] The axial direction of the mounting hole 141 at the end of the extension arm 14 is parallel to the second set direction of the flow channel plate 13, wherein the second set direction is perpendicular to both the first set direction and the thickness direction of the flow channel plate 13.

[0050] In this embodiment, the multi-way valve 11 and the heat exchanger 12 located on the second plate side 13b of the flow channel plate 13 are arranged sequentially along a first predetermined direction. Based on this, the axial direction of the mounting holes 141 of each extension arm 14 is perpendicular to the first predetermined direction and also perpendicular to the thickness direction of the flow channel plate 13. That is, the axial direction of the mounting holes 141 of each extension arm 14 is parallel to a second predetermined direction. Figure 3 The s2 direction in the middle.

[0051] Thus, as Figure 5-8 When the multi-way valve integrated device 1 is installed in the engine compartment, it can be inserted downwards into the engine compartment with the second set direction of the flow channel plate 13 parallel to the vertical direction of the vehicle, i.e., the z-axis direction, until the end of the extension arm 14 vertically abuts against the corresponding position on the vehicle body. At this time, the axis of the mounting hole 141 at the end of the extension arm 14 is vertical, which facilitates the installation of bolts and the removal of bolts during subsequent maintenance. Furthermore, with the engine compartment cover open, the multi-way valve 11 and heat exchanger 12 arranged sequentially along the first set direction in the installed and fixed multi-way valve integrated device 1 can be exposed in the field of vision, which is convenient for viewing and maintenance. Secondly, at this time, the first set direction of the flow channel plate 13 is parallel to (or approximately parallel to) the horizontal plane, i.e., the XY plane, which ensures that the arrangement of the multi-way valve 11 and heat exchanger 12 does not occupy too much of the relatively limited vertical space in the engine compartment.

[0052] See Figure 1-3 as well as Figure 5-8 Optionally, multiple extension arms 14 are provided. On the plane formed by the thickness direction of the flow channel plate 13 and the first set direction, at least some of the projections of the mounting holes 141 of the extension arms 14 do not coincide with the projections of the flow channel plate 13, the multi-way valve 11, and the heat exchanger 12.

[0053] And / or, in the second designated direction, at least a portion of the mounting hole 141 of the extension arm 14 is spaced apart from the heat exchanger 12 or the multi-way valve 11.

[0054] In this embodiment, as described above, when the multi-way valve integration device 1 is installed in the engine compartment, the second setting direction of the flow channel plate 13 is parallel to the vertical direction of the vehicle. Based on this, the plane formed by the thickness direction of the flow channel plate 13 and the first setting direction is a horizontal plane; on this horizontal plane, the projections of the mounting holes 141 of at least a portion of the extension arms 14 do not coincide with the projections of the flow channel plate 13, the multi-way valve 11, and the heat exchanger 12, respectively. Specifically, as shown... Figure 1 and Figure 8 As shown, since the projections of the mounting holes 141 of at least a portion of the extension arms 14 do not coincide with the projections of the flow channel plate 13, the multi-way valve 11, and the heat exchanger 12, respectively, that is, at least a portion of the mounting holes 141 of the extension arms 14 are not covered by the flow channel plate 13, the multi-way valve 11, or the heat exchanger 12 (see...). Figure 1 and Figure 8 (As shown in the top view), this ensures that the bolts at the mounting holes 141 can be quickly and easily installed or removed in the vertical direction of the vehicle. This part has two extension arms 14, for example, namely the first extension arm 14a and the second extension arm 14b shown in the figure.

[0055] Specifically, such as Figure 2-3 as well as Figure 5-6 As shown, even though the ends of at least a portion of the extension arms 14 are located directly below the heat exchanger 12 or the multi-way valve 11, the mounting holes 141 of these extension arms 14 are vertically spaced from the heat exchanger 12 or the multi-way valve 11. For example, one such extension arm 14, specifically the third extension arm 14c shown in the figure, has its end located directly below the heat exchanger 12. However, because there is a vertical gap between the mounting holes 141 at its end and the heat exchanger 12, tools can be used to remove or install bolts from these mounting holes 141 at the vertical gap between the mounting holes 141 and the heat exchanger 12.

[0056] Another embodiment of this utility model provides a vehicle thermal management system, including the multi-way valve integrated device 1 as described above.

[0057] Since the technical improvements and effects of the vehicle thermal management system are the same as those of the multi-way valve integrated device 1, the vehicle thermal management system will not be described in detail again.

[0058] Among them, such as Figure 4 As shown, for hybrid vehicles, the vehicle thermal management system includes not only the multi-way valve integration device 1, but also four subsystems: the battery water cooling system 4, the motor water cooling system 5, the engine water cooling system 3, and the air conditioning system 6. The four subsystems are connected to the multi-way valve integration device 1, thereby enabling heat exchange between the heat load (or cold load) of the four subsystems and improving the vehicle thermal management efficiency.

[0059] Another embodiment of the present invention provides a vehicle, including the multi-way valve integrated device 1 or the vehicle thermal management system as described above.

[0060] Since the technical improvements and effects of the vehicle are the same as those of the multi-way valve integrated device 1 or the vehicle thermal management system, the vehicle will not be described in detail again.

[0061] See Figure 5-8 Optionally, the vehicle further includes an engine mount 21 and a nacelle longitudinal beam 22, wherein the engine mount 21 is disposed on the upper side of the nacelle longitudinal beam 22, and the multi-way valve integration device 1 is located above the engine mount 21 and is fixed relative to the nacelle longitudinal beam 22.

[0062] In this embodiment, as Figure 5As shown, the multi-way valve integration device 1 is located above the engine mount 21 and is fixed relative to the engine compartment longitudinal beam 22. The multi-way valve integration device 1 does not occupy much or no additional lateral or longitudinal space in the engine compartment. Moreover, since the multi-way valve integration device 1 is located above the engine mount 21, it does not affect the arrangement of the engine between the left and right engine compartment longitudinal beams 22. It also facilitates the installation of external pipelines at the external pipeline interface 131 and facilitates subsequent maintenance. Specifically, the multi-way valve integration device 1 being located on the upper side of an engine mount 21 means at least that the flow channel plate 13, the multi-way valve 11, and the heat exchanger 12 are located on the upper side of that engine mount 21.

[0063] It should be noted that, similar to related technologies, vehicles typically include two engine mounts 21 and two engine compartment longitudinal beams 22. The engine mounts 21 are installed on the upper side of each engine compartment longitudinal beam 22, meaning that one engine mount 21 is installed on the upper side of each engine compartment longitudinal beam 22. In this way, the engine can be located between the two engine compartment longitudinal beams 22 and connected to the engine mounts 21 on both sides. The engine then uses the engine mounts 21 for vibration damping to prevent significant vibration during engine operation. In this embodiment, the multi-way valve integration device 1 can be located above any one of the engine mounts 21 and fixed relative to the corresponding engine compartment longitudinal beam 22.

[0064] See Figure 5-8 Optionally, the vehicle also includes a cabin side beam 23, which is an arc-shaped structure protruding outwards from the vehicle. In the longitudinal direction of the vehicle, the multi-way valve integration device 1 and the engine mount 21 are both located behind the front end of the cabin side beam 23.

[0065] In this embodiment, as Figure 7-8 As shown, the engine compartment side beam 23 is located outside the engine compartment longitudinal beam 22 and can be an arc-shaped structure protruding outwards from the vehicle. In the longitudinal direction of the vehicle, the multi-way valve integration device 1 is located behind the front end of the engine compartment side beam 23. Thus, the arc-shaped engine compartment side beam 23 can provide a certain degree of collision protection for the multi-way valve integration device 1, the engine mount 21, and the rear passenger compartment. For example, when a collision occurs, the other vehicle squeezes the anti-collision beam and the engine compartment longitudinal beam 22 until the front end of the engine compartment side beam 23. The other vehicle will slide outwards along the arc-shaped engine compartment side beam 23, which can prevent the engine mount 21 below the multi-way valve integration device 1 from being impacted to a certain extent, and can also prevent the passenger compartment from being intruded to a certain extent, thus improving passenger safety.

[0066] See Figure 8Optionally, the first setting direction of the multi-way valve integration device 1 is set at an angle to the longitudinal direction of the vehicle, and the rear end of the multi-way valve integration device 1 is inclined toward the engine compartment side beam 23. The second setting direction of the multi-way valve integration device 1 is parallel to the vertical direction of the vehicle, and the second plate side 13b of the flow channel plate 13 of the multi-way valve integration device 1 faces the engine compartment side beam 23.

[0067] In this embodiment, as Figure 8 As shown, the multi-way valve integrated device 1, after installation and fixation, has its first set direction set horizontally and at an angle to the longitudinal direction of the vehicle, that is, the s1 direction is at an angle to the X-axis direction, for example, the included angle θ between the two is 27°. In the case of the first set direction being horizontal, the second set direction of the multi-way valve integrated device 1 is also parallel to the vertical direction of the vehicle, thereby ensuring that the axial direction of the mounting holes 141 at the ends of each extension arm 14 is vertical, facilitating the installation and removal of the multi-way valve integrated device 1.

[0068] Furthermore, since the second plate side 13b of the flow channel plate 13 of the multi-way valve integration device 1 faces the engine compartment side beam 23; that is, the external pipe interface 131 of the first plate side 13a of the flow channel plate 13 does not face the outside of the vehicle, but faces the middle of the vehicle's lateral direction, the external pipe interface 131 of the first plate side 13a facilitates connection with most other components or modules of the vehicle's thermal management system in the engine compartment via external pipes. In addition, the rear end of the multi-way valve integration device 1 is inclined towards the engine compartment side beam 23, that is, the end of the multi-way valve integration device 1 near the rear of the vehicle extends outward along the first set direction, that is, the rear end of the multi-way valve integration device 1 is close to the outer side beam 23 of the engine compartment. This allows the external pipe interface 131 of the first plate side 13a of the flow channel plate 13 to be as far away from the middle of the vehicle's lateral direction as possible. After the external pipe interface 131 of the first plate side 13a is connected to the corresponding external component or module through a pipe, this part of the pipe can be a relatively long pipe with a certain degree of slack, rather than a taut pipe. Thus, when it is necessary to disassemble the engine mount 21 below the multi-way valve integration device 1, this part of the pipe does not need to be disassembled. Instead, the slack of this part of the pipe can be used to push the pipe aside, thereby making room for disassembly and removal of the engine mount 21.

[0069] See Figure 5-6 and Figure 8 Optionally, the vehicle further includes a side beam connecting plate 24, through which at least a portion of the lower side of the engine compartment side beam 23 in its extending direction is connected to the engine compartment longitudinal beam 22.

[0070] In this embodiment, since the engine compartment side beam 23 is an arc-shaped structure protruding outwards from the vehicle, there will be a lateral gap between the engine compartment side beam 23 and the engine compartment longitudinal beam 22. On this basis, at least part of the lower side of the engine compartment side beam 23 in its extension direction, such as the lower side of the front part of the engine compartment side beam 23, can be connected to the engine compartment longitudinal beam 22 through the side beam connecting plate 24, thereby improving the connection strength between the engine compartment side beam 23 and the engine compartment longitudinal beam 22. Moreover, when the vehicle is involved in a frontal collision, the gradually collapsing engine compartment longitudinal beam 22 can also transfer the force to the engine compartment side beam 23 through the side beam connecting plate 24, avoiding excessive force concentration and improving the overall collision avoidance effect of the vehicle.

[0071] See Figure 5-6 and Figure 8 Optionally, the multi-way valve integration device 1 is connected to the engine compartment longitudinal beam 22 and / or the side beam connecting plate 24 via an extension arm 14; and / or, the vehicle further includes an engine compartment tower package 25 located behind the flow channel plate 13 of the multi-way valve integration device 1, and the multi-way valve integration device 1 is connected to the engine compartment tower package 25 via an extension arm 14.

[0072] In this embodiment, as mentioned above, to ensure the stability of the multi-way valve integration device after installation, multiple extension arms 14 can be provided, such as the aforementioned first extension arm 14a, second extension arm 14b, and third extension arm 14c. The multi-way valve integration device 1 can be mounted on the nacelle longitudinal beam 22 via a portion of the extension arms 14. In addition, the side beam connecting plate 24 located between the nacelle side beam 23 and the nacelle longitudinal beam 22 can also support at least a portion of the ends of the extension arms 14. That is, the multi-way valve integration device 1 can be connected to the side beam connecting plate 24 via at least a portion of the extension arms 14.

[0073] The extension arm 14 may have a mounting hole 141 at its end. When installing the extension arm 14, fasteners can be used to connect the mounting hole 141 at the end of the extension arm 14 to the nacelle longitudinal beam 22 and / or the side beam connecting plate 24, facilitating easy assembly and disassembly. Figure 5-6 As shown, the mounting holes 141 at the ends of the second extension arm 14b and the third extension arm 14c can both be mounted on the side beam connecting plate 24 by fasteners, thereby easily avoiding the engine mount 21 below the flow channel plate 13; the fasteners can be bolts.

[0074] Alternatively, at least a portion of the end of the extension arm 14 can be mounted on the nacelle tower package 25 behind the flow channel plate 13, meaning the multi-way valve integration device 1 is connected and fixed to the nacelle tower package 25 via at least a portion of the extension arm 14. For example... Figure 6 and Figure 8As shown, the first extension arm 14a extends to the rear and lower part of the flow channel plate 13. The end of the first extension arm 14a is supported at the nacelle tower 25. The end of the first extension arm 14a may be provided with a mounting hole 141, and then the mounting hole 141 at the end of the first extension arm 14a can be connected and fixed to the nacelle tower 25 using fasteners. Finally, multiple extension arms 14, while avoiding the engine mount 21, are also installed at different positions in the nacelle, which can improve the stability of the multi-way valve integration device 1 and the convenience of disassembly and assembly.

[0075] In other embodiments, the extension arm 14 may be installed and fixed in the nacelle by means of welding or snap-fitting. For example, the ends of the second extension arm 14b and the third extension arm 14c may be installed at the side beam connecting plate 24 by welding or snap-fitting, and the end of the first extension arm 14a may be installed at the nacelle tower pack 25 by welding or snap-fitting.

Therefore, a feature defined as "first" and "second" may explicitly or implicitly include at least one of those features.

[0077] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
