In addition, the reservoirs are usually located on the side of the engine compartment crossbeam near the rear of the vehicle, which makes it inconvenient to refill them daily. Utility Model Content

[0004] The purpose of this application is to provide a vehicle engine compartment crossbeam structure and the vehicle thereof, which not only saves engine compartment space and improves the utilization rate of engine compartment crossbeams, but also facilitates the filling of water tanks.

[0005] The first aspect of this application discloses a vehicle engine compartment crossbeam structure, comprising: an engine compartment crossbeam and a first partition, the engine compartment crossbeam being connected to a vehicle's shock absorber tower, the engine compartment crossbeam having a receiving cavity for containing coolant; the first partition is located within the receiving cavity and connected to the cavity wall of the receiving cavity, the first partition dividing the receiving cavity into a first cavity and a second cavity that are independent of each other, both the first cavity and the second cavity being used to communicate with the vehicle's thermal management system.

[0006] In one exemplary embodiment of this application, the cabin beam structure further includes a second partition, which is located within the second cavity and connected to the cavity wall of the second cavity. The second partition divides the second cavity into a first sub-cavity and a second sub-cavity, both of which are used to communicate with the vehicle's thermal management system.

[0007] In one exemplary embodiment of this application, the first partition includes a first partition portion and a second partition portion spaced apart from each other, and both the first partition portion and the second partition portion are connected to the cavity wall of the accommodating cavity.

[0008] In one exemplary embodiment of this application, the first partition includes a first side and a second side, the first side and the second side being disposed opposite to each other along the direction from the first cavity toward the second cavity; the first side is provided with a first heat-insulating coating; and / or, the second side is provided with a second heat-insulating coating.

[0009] In one exemplary embodiment of this application, the cabin crossbeam is further provided with a first liquid inlet and a second liquid inlet spaced apart from each other. The first liquid inlet is connected to the first cavity, and the second liquid inlet is connected to the second cavity. The cabin crossbeam also includes a first lid and a second lid, the first lid covering the first liquid inlet and the second lid covering the second liquid inlet.

[0010] In one exemplary embodiment of this application, the cabin beam further includes a first liquid level sensor and a second liquid level sensor. The first liquid level sensor is located in the first cavity and connected to the cavity wall of the first cavity, and the second liquid level sensor is located in the second cavity and connected to the cavity wall of the second cavity.

[0011] In one exemplary embodiment of this application, the cabin crossbeam includes a cavity portion and a connecting portion, the cavity portion being connected to the connecting portion, and the accommodating cavity being located in the cavity portion; the connecting portion is provided with a first mounting hole, and a fastener passes through the first mounting hole to connect the connecting portion to the vehicle's shock absorber tower package.

[0012] In one exemplary embodiment of this application, the nacelle beam structure further includes a support member, one end of which is connected to the nacelle beam, and the other end of which is used to connect to the vehicle's shock absorber tower pack.

[0013] In one exemplary embodiment of this application, the support member is provided with a second mounting hole, and a fastener passes through the second mounting hole to connect the support member to the vehicle's shock absorber tower; the connection between the support member and the engine compartment crossbeam forms a first connection point, and the first connection point, the first mounting hole, and the second mounting hole respectively constitute the three vertices of a triangle.

[0014] The second aspect of this application discloses a vehicle including a shock absorber tower, a thermal management system, and the aforementioned engine compartment crossbeam structure.

[0015] The proposed solution has the following beneficial effects: In this embodiment, since the first partition divides the accommodating cavity into two independent chambers, and both chambers can be connected to the vehicle's thermal management system, the first chamber can be connected to the engine circuit of the thermal management system to replenish or recover coolant from the engine circuit; the second chamber can be connected to the battery circuit and electric drive circuit of the thermal management system to replenish or recover coolant from the battery circuit and electric drive circuit. Therefore, the engine compartment crossbeam structure of this application integrates multiple coolant reservoirs into the engine compartment crossbeam, eliminating the need for separate additional coolant reservoirs, which helps save engine compartment space and improve the utilization rate of the engine compartment crossbeam; furthermore, the integrated design positions the coolant reservoirs more forward for easier refilling.

[0028] like Figures 1 to 4 As shown, this embodiment provides a vehicle engine compartment crossbeam structure, including: an engine compartment crossbeam 1 and a first partition 2. The engine compartment crossbeam 1 is used to connect with the vehicle's shock absorber tower 3. The engine compartment crossbeam 1 is provided with a receiving cavity 101 for containing coolant. The first partition 2 is located inside the receiving cavity 101 and is connected to the cavity wall of the receiving cavity 101. The first partition 2 divides the receiving cavity 101 into two independent cavities 101a and 101b. Both the first cavity 101a and the second cavity 101b are used to communicate with the vehicle's thermal management system.

[0029] In this embodiment, the engine compartment crossbeam 1 is bolted between the two damping towers 3 of the vehicle, which helps to increase the strength of the engine compartment structure and improve the torsional and modal performance of the vehicle body.

[0030] In this embodiment, combined with Figure 1 and Figure 3 As shown, the engine room crossbeam 1 is also provided with a first liquid outlet 102 and a second liquid outlet 103 spaced apart from each other. The first liquid outlet 102 is connected to the first cavity 101a, and the first cavity 101a is connected to the engine circuit of the thermal management system through the first liquid outlet 102. The second liquid outlet 103 is connected to the second cavity 101b, and the second cavity 101b is connected to the battery circuit and electric drive circuit of the thermal management system through the second liquid outlet 103.

[0031] In this embodiment, since the first partition 2 divides the accommodating cavity 101 into two independent chambers, a first chamber 101a and a second chamber 101b, and both chambers 101a and 101b can be connected to the vehicle's thermal management system, the first chamber 101a can be connected to the engine circuit of the thermal management system to replenish or recover coolant in the engine circuit; the second chamber 101b can be connected to the battery circuit and electric drive circuit of the thermal management system to replenish or recover coolant in the battery circuit and electric drive circuit. Therefore, the engine compartment crossbeam structure of this application integrates multiple water tanks into the engine compartment crossbeam 1, eliminating the need for separate additional water tanks, which helps save engine compartment space and improve the utilization rate of the engine compartment crossbeam 1; in addition, the integrated design allows the water tanks to be positioned further forward for easy filling.

[0032] It should be understood that when the coolant temperature in the thermal management system loop rises and its volume expands, the reservoir will recycle the coolant from the loop. When the coolant temperature in the thermal management system loop drops and its volume contracts (or coolant is consumed), the reservoir will replenish the loop with coolant.

[0033] It should be understood that the coolant temperature in the engine circuit is relatively high, and the first chamber 101a is a high-temperature region, meaning that the portion of the engine compartment beam 1 corresponding to the first chamber 101a is a high-temperature coolant reservoir. The coolant temperature in the battery circuit and the electric drive circuit is relatively low, and the second chamber 101b is a low-temperature region, meaning that the portion of the engine compartment beam 1 corresponding to the second chamber 101b is a low-temperature coolant reservoir.

[0034] In other embodiments, the first cavity 101a may be connected to the battery circuit and the electric drive circuit of the thermal management system to replenish or recover the coolant in the battery circuit and the electric drive circuit; the second cavity 101b may be connected to the engine circuit of the thermal management system to replenish or recover the coolant in the engine circuit.

[0035] It should be understood that the thermal management system in range-extended or hybrid vehicles includes an engine circuit, a battery circuit, and an electric drive circuit, and each of these circuits requires a coolant reservoir.

[0036] In other embodiments, in a pure electric vehicle: the first cavity 101a can be connected to the battery circuit of the thermal management system to replenish or recover the coolant in the battery circuit; the second cavity 101b can be connected to the electric drive circuit of the thermal management system to replenish or recover the coolant in the electric drive circuit.

[0037] It should be understood that the thermal management system in pure electric vehicles only includes the battery circuit and the electric drive circuit, and both the battery circuit and the electric drive circuit need to be equipped with a water tank.

[0038] In this embodiment, combined with Figure 1 and Figure 2 As shown, the first partition 2 is arranged vertically within the accommodating cavity 101 along the width direction x of the cabin beam 1.

[0039] In other embodiments, the first partition 2 is disposed within the accommodating cavity 101 along the length direction y of the cabin beam 1, i.e., arranged laterally. Alternatively, the first partition 2 is disposed obliquely within the accommodating cavity 101.

[0040] It should be understood that the arrangement position of the first partition 2 can be selected according to the actual situation, as long as the first partition 2 can divide the accommodating cavity 101 into a first cavity 101a and a second cavity 101b that are independent of each other.

[0041] Furthermore, the cabin beam structure also includes a second partition, which is located inside the second cavity 101b and connected to the cavity wall of the second cavity 101b. The second partition divides the second cavity 101b into a first sub-cavity and a second sub-cavity, both of which are used to communicate with the vehicle's thermal management system.

[0042] In other embodiments, the second partition further divides the second cavity 101b into two independent sub-cavities: a first sub-cavity and a second sub-cavity. The first sub-cavity can be connected to the battery circuit of the thermal management system to replenish or recover coolant in the battery circuit; the second sub-cavity can be connected to the electric drive circuit of the thermal management system to replenish or recover coolant in the electric drive circuit. By further dividing the second cavity 101b by the second partition, the first and second sub-cavities are connected one-to-one with the battery circuit and the electric drive circuit, meaning each independent circuit is equipped with a coolant reservoir to meet different needs.

[0043] In other embodiments, the second liquid outlet 103 is connected to the first sub-cavity, and the first sub-cavity is connected to the thermal management system through the second liquid outlet 103. The cabin beam 1 is also provided with a third liquid outlet, which is spaced apart from the first liquid outlet 102 and the second liquid outlet 103. The third liquid outlet is connected to the second sub-cavity, and the second sub-cavity is connected to the thermal management system through the third liquid outlet.

[0044] It should be understood that whether or not to install a second divider can be chosen based on actual needs.

[0045] In other embodiments, the second partition may be arranged vertically, horizontally, or obliquely within the second cavity 101b.

[0046] It should be understood that the arrangement of the second partition can be selected according to the actual situation, as long as the second partition can divide the second cavity 101b into an independent first sub-cavity and a second sub-cavity.

[0047] In other embodiments, the second partition is located inside the first cavity 101a and connected to the cavity wall of the first cavity 101a. The second partition divides the first cavity 101a into a first sub-cavity and a second sub-cavity that are independent of each other. Both the first sub-cavity and the second sub-cavity are used to communicate with the vehicle's thermal management system.

[0048] In other embodiments, combined with Figure 1 and Figure 5 As shown, the first partition 2 includes a first partition portion 21 and a second partition portion 22 spaced apart from each other. Both the first partition portion 21 and the second partition portion 22 are connected to the cavity wall of the accommodating cavity 101. The first partition portion 21 and the second partition portion 22 are spaced apart to prevent the coolant in the first cavity 101a and the coolant in the second cavity 101b from directly conducting heat through the first partition 2, thereby reducing heat transfer.

[0049] Combination Figure 1 and Figure 3As shown, the first partition 2 includes a first side 2a and a second side 2b, which are arranged opposite to each other along the direction from the first cavity 101a toward the second cavity 101b; the first side 2a is provided with a first heat insulation coating; and the second side 2b is provided with a second heat insulation coating.

[0050] In this embodiment, the first side 2a is provided with a first heat-insulating coating, and the second side 2b is provided with a second heat-insulating coating. The provision of the first heat-insulating coating and the second heat-insulating coating can reduce the heat transfer between the coolant in the first cavity 101a and the coolant in the second cavity 101b.

[0051] In other embodiments, the first side 2a is provided with a first heat-insulating coating; or, the second side 2b is provided with a second heat-insulating coating.

[0052] In other embodiments, combined with Figure 5 As shown, the first side 2a is the side of the first partition 21 that is away from the second partition 22; the second side 2b is the side of the second partition 22 that is away from the first partition 21.

[0053] For example, both the first and second heat insulation coatings can be made of aerogel materials.

[0054] It should be understood that, since both the first partition 2 and the second partition are used to separate cavities, the second partition can refer to the thermal insulation structural design of the first partition 2.

[0055] In this embodiment, the nacelle beam 1 is further provided with a first liquid inlet and a second liquid inlet spaced apart from each other. The first liquid inlet communicates with the first cavity 101a, and the second liquid inlet communicates with the second cavity 101b. When the liquid level in the first cavity 101a is lower than the minimum scale line, coolant needs to be added through the first liquid inlet until the liquid level is between the minimum and maximum scale lines to maintain the normal operation of the thermal management system. When the liquid level in the second cavity 101b is lower than the minimum scale line, coolant needs to be added through the second liquid inlet until the liquid level is between the minimum and maximum scale lines to maintain the normal operation of the thermal management system.

[0056] It should be understood that over time, coolant will slowly decrease due to minor evaporation or small leaks.

[0057] Combination Figure 1 As shown, the cabin beam 1 also includes a first liquid inlet 41 and a second liquid inlet 42. The first liquid inlet 41 covers the first liquid inlet, and the second liquid inlet 42 covers the second liquid inlet.

[0058] In this embodiment, the first cap 41 and the second cap 42 serve to seal and prevent contamination. The first cap 41 not only seals the first cavity 101a, preventing coolant from splashing out or evaporating during vehicle movement, but also prevents external dust, impurities, and other contaminants from entering the cooling system, thus maintaining the cleanliness of the coolant. The second cap 42 not only seals the second cavity 101b, preventing coolant from splashing out or evaporating during vehicle movement, but also prevents external dust, impurities, and other contaminants from entering the cooling system, thus maintaining the cleanliness of the coolant.

[0059] In this embodiment, the cabin beam 1 also includes a first liquid level sensor and a second liquid level sensor. The first liquid level sensor is located in the first cavity 101a and is connected to the cavity wall of the first cavity 101a. The second liquid level sensor is located in the second cavity 101b and is connected to the cavity wall of the second cavity 101b.

[0060] In this embodiment, the first liquid level sensor can monitor the liquid level in the first cavity 101a in real time. When the liquid level is abnormal (too high, too low, or changes drastically), the first liquid level sensor will promptly issue an alarm or send an alarm to the monitoring center to remind the driver to take timely action. The second liquid level sensor can monitor the liquid level in the second cavity 101b in real time. When the liquid level is abnormal (too high, too low, or changes drastically), the second liquid level sensor will promptly issue an alarm or send an alarm to the monitoring center to remind the driver to take timely action.

[0061] Combination Figure 1 As shown, the cabin beam 1 also includes a first exhaust pipe 51 and a second exhaust pipe 52. The first exhaust pipe 51 is connected to the first cavity 101a, and the second exhaust pipe 52 is connected to the second cavity 101b.

[0062] In this embodiment, the first exhaust pipe 51 connects the inside and outside of the first cavity 101a, allowing the gas inside the first cavity 101a to be discharged to the outside, thus ensuring that the pressure inside the first cavity 101a is consistent with atmospheric pressure. The second exhaust pipe 52 connects the inside and outside of the second cavity 101b, allowing the gas inside the second cavity 101b to be discharged to the outside, thus ensuring that the pressure inside the second cavity 101b is consistent with atmospheric pressure.

[0063] In this embodiment, combined with Figure 1 and Figure 3As shown, the cabin beam 1 includes a top plate a and a bottom plate b, which are arranged opposite each other along the thickness direction z of the cabin beam 1. The first exhaust pipe 51 and the second exhaust pipe 52 are both located on the top plate a to facilitate gas discharge; the first liquid inlet and the second liquid inlet are both located on the top plate a to facilitate the pilot to add coolant; the first liquid outlet 102 and the second liquid outlet 103 are both located on the bottom plate b to facilitate the replenishment and recovery of coolant.

[0064] In other embodiments, the first sub-cavity is connected to the second liquid inlet and the second vent pipe 52. The second liquid level sensor is located in the first sub-cavity and connected to the cavity wall of the first sub-cavity. The cabin beam 1 also includes a third liquid inlet, a third lid, a third vent pipe, and a third liquid level sensor. The third lid covers the third liquid inlet. The third liquid inlet and the third vent pipe are both connected to the second sub-cavity. The third liquid level sensor is located in the second sub-cavity and connected to the cavity wall of the second sub-cavity. The first sub-cavity and the second sub-cavity are each provided with an independent liquid inlet, vent pipe, and liquid level sensor.

[0065] Combination Figures 1 to 4 As shown, the cabin crossbeam 1 includes a cavity portion 11 and a connecting portion 12. The cavity portion 11 is connected to the connecting portion 12, and the accommodating cavity 101 is located in the cavity portion 11. The connecting portion 12 is provided with a first mounting hole, and fasteners pass through the first mounting hole to connect the connecting portion 12 to the vehicle's shock absorber tower package 3.

[0066] In this embodiment, the cabin crossbeam 1 is made of aluminum profile, and the two sides of the cabin crossbeam 1 form a closed accommodating cavity 101 through the spacer 8. The connecting part 12 includes a first connecting part 121 and a second connecting part 122 that are identical in shape and size. The first connecting part 121 and the second connecting part 122 are respectively disposed on two opposite sides of the cavity part 11 along the length direction y of the cabin crossbeam 1. The first connecting part 121 connects the cavity part 11 to one vibration damping tower 3, and the second connecting part 122 connects the cavity part 11 to another vibration damping tower 3.

[0067] In this embodiment, the fastener is a bolt. Both the first connecting part 121 and the second connecting part 122 have two mutually spaced first mounting holes. Four bolts pass through the four first mounting holes one-to-one to connect the first connecting part 121 to the vibration damping tower package 3 and the second connecting part 122 to the vibration damping tower package 3. The first connecting part 121 and the vibration damping tower package 3 are connected by bolts, and the second connecting part 122 and the vibration damping tower package 3 are connected by bolts to facilitate installation and disassembly.

[0068] In addition, the first mounting hole is located at the connection part 12 to avoid the setting of the first mounting hole affecting the sealing of the receiving cavity 101.

[0069] In this embodiment, the first liquid inlet is located on the side of the cavity 11 near the first connecting part 121, and the second liquid inlet is located on the side of the cavity 11 near the second connecting part 122, so that the driver can add coolant.

[0070] Combination Figure 1 and Figure 4 As shown, the nacelle crossbeam structure also includes a support member 6, one end of which is connected to the nacelle crossbeam 1, and the other end of which is used to connect to the vehicle's shock absorber tower package 3.

[0071] In this embodiment, the cabin crossbeam 1 includes a first side plate c and a second side plate d. The first side plate c and the second side plate d are arranged opposite each other along the width direction x of the cabin crossbeam 1, and the first side plate c is further away from the rear of the vehicle than the second side plate d. The support member 6 includes a first support rod 61 and a second support rod 62 with the same shape and size. One end of the first support rod 61 is connected to the first side plate c by welding, and the other end of the first support rod 61 is connected to a vibration damping tower 3. One end of the second support rod 62 is connected to the first side plate c by welding, and the other end of the second support rod 62 is connected to another vibration damping tower 3. The first support rod 61 and the second support rod 62 can further increase the stability and reliability of the cabin crossbeam 1.

[0072] Combination Figure 1 and Figure 4 As shown, the support member 6 is provided with a second mounting hole, through which fasteners pass to connect the support member 6 to the vehicle's shock absorber tower 3; the connection between the support member 6 and the engine compartment crossbeam 1 forms a first connection point, and the first connection point, the first mounting hole, and the second mounting hole respectively form the three vertices of a triangle.

[0073] In this embodiment, both the first support rod 61 and the second support rod 62 are provided with two mutually spaced second mounting holes. Four bolts pass through the four second mounting holes one by one to connect the first support rod 61 to the vibration damping tower package 3 and the second support rod 62 to the vibration damping tower package 3. The first support rod 61 is bolted to one vibration damping tower package 3, and the second support rod 62 is bolted to another vibration damping tower package 3 to facilitate installation and disassembly.

[0074] In this embodiment, the nacelle crossbeam structure further includes a first bushing 71 and a second bushing 72. The first bushing 71 is disposed between the bolt and the first mounting hole, and the second bushing 72 is disposed between the bolt and the second mounting hole. The first bushing 71 provides support to prevent the nacelle crossbeam 1 from deforming due to the lateral force between the two vibration damping towers 3. The second bushing 72 provides support to prevent the support member 6 from deforming due to the external force.

[0075] In this embodiment, combined with Figure 1 and Figure 4 As shown, when the first connecting part 121 and the first support rod 61 are connected to a vibration damping tower 3, one end of the first support rod 61 is connected to the first side plate c and forms a first connection point; the other end of the first support rod 61 is connected to the vibration damping tower 3 through the second mounting hole by bolts and forms a second connection point; the first connecting part 121 is connected to the vibration damping tower 3 through the first mounting hole by bolts and forms a third connection point; the first connection point, the second connection point, and the third connection point respectively form the three vertices of a triangle, which is beneficial to improving the stability and reliability of the connection between the cabin beam structure and the vibration damping tower 3.

[0076] It should be understood that the above description only describes the connection between the first connecting part 121 and the first support rod 61 and one vibration damping tower package 3. The connection between the second connecting part 122 and the second support rod 62 and another vibration damping tower package 3 can be implemented with reference to this description.

[0077] This embodiment also provides a vehicle, including a shock absorber tower 3, a thermal management system and the above-mentioned engine compartment crossbeam structure.
