Description

Technical Field

[0001] This application relates to the field of transportation technology, and in particular to an automobile. Background Technology

[0002] With the continuous development of automotive technology, electric and hybrid vehicles are becoming increasingly popular. In these vehicles, the cooling system primarily consists of cooling pipes routed to the areas requiring cooling and connected to the radiator. Improper installation of these cooling pipes can not only lead to cramped interior space but also negatively impact the cooling system's effectiveness, potentially causing the powertrain to overheat and increasing the risk of malfunctions.

[0003] Currently, in new energy vehicles, to make efficient use of space, the onboard power supply is often installed in the spare tire well in the trunk. Because the space between the spare tire well and the rear crossbeam of the subframe is relatively narrow, the cooling pipes used to dissipate heat from the onboard power supply can only extend from the left, right, bottom, or rear sides of the spare tire well, connecting to the cooling pipes and coolant inlet pipes of the electric drive unit located in the subframe. Obviously, this arrangement results in long cooling lines, requiring a significant amount of space and leading to low space utilization. Furthermore, the long pipes also cause energy loss during coolant transmission, resulting in low cooling efficiency when the coolant is introduced into the onboard power supply. Utility Model Content

[0004] Therefore, it is necessary to provide a car that can save space and shorten the length of water pipes.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A car, the car comprising:

[0007] Subframe rear crossbeam assembly;

[0008] The rear floor spare tire compartment is arranged at intervals from the subframe rear crossbeam assembly along the length of the vehicle. The rear floor spare tire compartment includes a sidewall, which faces the subframe rear crossbeam assembly.

[0009] The vehicle power supply is installed in the spare tire compartment of the rear floor, and a cooling pipe is connected to the vehicle power supply.

[0010] A water inlet pipe is installed on the rear crossbeam assembly of the subframe. The water inlet pipe has a drain end, which is located between the rear crossbeam assembly of the subframe and the spare tire compartment of the rear floor, and passes through the side wall to connect with the cooling pipe.

[0011] The water outlet pipe is installed on the rear crossbeam assembly of the subframe. The water outlet pipe has a water inlet end, which is located between the rear crossbeam assembly of the subframe and the spare tire compartment of the rear floor, and passes through the side wall to connect with the cooling pipe.

[0012] Understandably, the connection between the cooling pipes used for vehicle power cooling and the inlet and outlet water pipes is located on the side wall of the spare tire compartment above the subframe rear crossbeam assembly and between the rear crossbeam assembly. This reduces the length of the pipes required to connect the cooling pipes to the inlet and outlet water pipes, thus optimizing the pipeline. On the one hand, this reduces the assembly space required for the pipelines and improves the vehicle's space utilization; on the other hand, it also reduces energy loss during the transmission of coolant within the pipelines, thereby improving the cooling efficiency of the coolant.

[0013] In one embodiment, the subframe rear crossbeam assembly includes a subframe rear crossbeam and a stabilizer bar, the stabilizer bar being mounted on the subframe rear crossbeam; wherein, a groove is formed on one end of the subframe rear crossbeam facing the side wall, the stabilizer bar is partially bent into the groove to form a bent portion, and the drain end and the water inlet end are at least partially disposed in the cavity enclosed by the bent portion.

[0014] Understandably, the grooves on the rear crossbeam of the subframe and the bends on the stabilizer bar are used to avoid the drain end of the inlet pipe and the inlet end of the outlet pipe. This satisfies the requirement that the cooling pipe extends from the rear floor spare tire compartment to the side wall of the rear crossbeam assembly of the subframe and is assembled and connected to the inlet and outlet pipes respectively. On the other hand, the stabilizer bar also protects the connection between the cooling pipe, the inlet pipe and the outlet pipe.

[0015] In one embodiment, the stabilizer bar is located below the rear crossbeam of the subframe in the vehicle height direction; the water inlet pipe and the water outlet pipe are both located above the rear crossbeam of the subframe in the vehicle height direction and are respectively connected to the rear crossbeam of the subframe.

[0016] Understandably, by placing both the inlet and outlet water pipes above the rear crossbeam of the subframe in the vehicle's height direction, it not only effectively protects the water pipes from damage caused by road debris or extreme environments, thus preventing abnormal cooling, but also makes full use of vertical space, resulting in a more rational and compact layout.

[0017] In one embodiment, a left suspension mounting bracket is provided on the rear crossbeam of the subframe, and the water inlet pipe is installed on the left suspension mounting bracket; a right suspension mounting bracket is provided on the rear crossbeam of the subframe, and the water outlet pipe is installed on the right suspension mounting bracket.

[0018] In one embodiment, a sealing plate is installed on the side wall, and the sealing plate is connected and communicates with the cooling pipe; wherein, the sealing plate has a first water inlet connector and a first water outlet connector, the first water inlet connector and the first water outlet connector are disposed through the side wall, and the first water inlet connector is communicated with the drain end, and the first water outlet connector is communicated with the water inlet end.

[0019] In one embodiment, the water inlet pipe is connected to and communicates with a first quick-connect fitting at the location of the drain end, the first quick-connect fitting being plugged into and communicating with the first water inlet fitting; the water outlet pipe is connected to and communicates with a second quick-connect fitting at the location of the water inlet end, the second quick-connect fitting being plugged into and communicating with the first water outlet fitting.

[0020] It is understandable that the water inlet pipe is connected to the first water inlet connector through the insertion and engagement of the first quick-connect fitting and the first water outlet connector, and the water outlet pipe is connected to the second water outlet connector through the insertion and engagement of the second quick-connect fitting and the second water outlet connector. This facilitates the assembly and connection between the water inlet pipe, the water outlet pipe and the sealing plate, and improves assembly efficiency.

[0021] In one embodiment, the sealing plate further has a second water inlet connector and a second water outlet connector, the second water inlet connector being connected to the first water inlet connector and the second water outlet connector being connected to the first water outlet connector; the cooling pipeline includes a cooling inlet pipe and a cooling outlet pipe, the cooling inlet pipe and the cooling outlet pipe being connected to and communicating with the vehicle power supply respectively, wherein the cooling inlet pipe is inserted into and communicates with the second water inlet connector, and the cooling outlet pipe is inserted into and communicates with the second water outlet connector.

[0022] In one embodiment, a sealing groove through hole is provided on the side wall, and the first water inlet connector and the first water outlet connector are disposed through the sealing groove through hole; wherein, the sealing plate is attached to the side wall and connected and sealed with the side wall to block the sealing groove through hole.

[0023] In one embodiment, the vehicle further includes an electric drive, and the water outlet pipe is connected to and communicates with the electric drive.

[0024] In one embodiment, the vehicle further includes a reduction gear shaft extending along the width of the vehicle; wherein the electric drive is disposed on the reduction gear shaft on one side facing the subframe rear crossbeam assembly.

[0025] Understandably, by placing the electric drive closer to the rear crossbeam assembly of the subframe, the layout around the electric drive becomes more compact. Since the electric drive is located in the rear seat area of ​​the car, placing it close to the rear crossbeam assembly of the subframe allows for more legroom in the rear seats.

[0026] Compared with the prior art, this application sets the connection between the cooling pipe for vehicle power supply heat dissipation and the inlet and outlet pipes at the side wall of the rear floor spare tire compartment facing the subframe rear crossbeam assembly and the rear crossbeam assembly. This reduces the length of the pipeline required to connect the cooling pipe with the inlet and outlet pipes, thus optimizing the pipeline. On the one hand, it reduces the assembly space required for the pipeline assembly and improves the space utilization of the vehicle; on the other hand, it can also reduce the energy loss of the cooling water during the transmission of the pipeline, thereby improving the cooling efficiency of the cooling water.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0041] like Figures 1 to 6 As shown, the automobile 100 provided in this application includes a subframe rear crossbeam assembly 10, a rear floor spare tire compartment 20, an onboard power supply 30, a water inlet pipe 50, and a water outlet pipe 60. The rear floor spare tire compartment 20 is arranged at intervals from the subframe rear crossbeam assembly 10 along the length of the automobile 100. The rear floor spare tire compartment 20 includes a side wall 21, which faces the subframe rear crossbeam assembly 10. The onboard power supply 30 is installed inside the rear floor spare tire compartment 20, and a cooling pipe is connected to and communicates with the onboard power supply 30. The water inlet pipe 50 is installed on the rear crossbeam assembly 10 of the subframe. The water inlet pipe 50 has a drain end 51, which is located between the rear crossbeam assembly 10 of the subframe and the spare tire compartment 20 of the rear floor, and passes through the side wall 21 to connect with the cooling pipe 40. The water outlet pipe 60 is installed on the rear crossbeam assembly 10 of the subframe. The water outlet pipe 60 has a water inlet end 61, which is located between the rear crossbeam assembly 10 of the subframe and the spare tire compartment 20 of the rear floor, and passes through the side wall 21 to connect with the cooling pipe 40.

[0042] As can be seen from the above, the vehicle 100 of this application sets the connection between the cooling pipe 40 for heat dissipation of the vehicle power supply 30 and the inlet pipe 50 and outlet pipe 60 on the side wall 21 of the rear floor spare tire compartment 20 facing the subframe rear crossbeam assembly 10 and the subframe rear crossbeam assembly 10. This reduces the length of the pipeline required when the cooling pipe 40 is connected to the inlet pipe 50 and outlet pipe 60, thus optimizing the pipeline. On the one hand, it can reduce the assembly space required when assembling the above-mentioned pipeline and improve the space utilization of the vehicle 100; on the other hand, it can also reduce the energy loss of the cooling water during the transmission of the pipeline, thereby improving the cooling efficiency of the cooling water.

[0043] like Figures 1 to 5 As shown, the subframe rear crossbeam assembly 10 includes a subframe rear crossbeam 11 and a stabilizer bar 12. A left suspension mounting bracket 111 is mounted on the subframe rear crossbeam 11, and a water inlet pipe 50 is mounted on the left suspension mounting bracket 111. A right suspension mounting bracket 112 is mounted on the subframe rear crossbeam 11, and a water outlet pipe 60 is mounted on the right suspension mounting bracket 112. Here, the water inlet pipe 50 and the water outlet pipe 60 can be fixedly mounted on the left suspension mounting bracket 111 and the right suspension mounting bracket 112 respectively using methods such as pipe clamps or fixing brackets. This is quite common in the prior art and will not be elaborated upon here.

[0044] In one embodiment, the stabilizer bar 12 is mounted on the rear crossbeam 11 of the subframe; wherein, a groove 113 is provided on one end of the rear crossbeam 11 of the subframe facing the side wall 21, the stabilizer bar 12 is partially bent into the groove 113 to form a bent portion 121, and the drain end 51 and the water inlet end 61 are at least partially disposed in the cavity 1211 enclosed by the bent portion 121. In this way, the groove 113 on the rear crossbeam 11 of the subframe and the bend 121 on the stabilizer bar 12 are used to avoid the drain end 51 of the inlet pipe 50 and the inlet end 61 of the outlet pipe 60. On the one hand, this can meet the usage requirements of the cooling pipe 40 extending from the rear floor spare tire compartment 20 to the side wall 21 of the rear crossbeam assembly 10 of the subframe and being assembled and connected to the inlet pipe 50 and the outlet pipe 60 respectively. On the other hand, the stabilizer bar 12 can also protect the connection between the cooling pipe 40, the inlet pipe 50 and the outlet pipe 60.

[0045] Furthermore, the stabilizer bar 12 is positioned below the rear crossbeam 11 of the subframe in the height direction of the vehicle 100; the inlet pipe 50 and outlet pipe 60 are both positioned above the rear crossbeam 11 of the subframe in the height direction of the vehicle 100, and are respectively connected to the rear crossbeam 11 of the subframe. By positioning the inlet pipe 50 and outlet pipe 60 above the rear crossbeam 11 of the subframe in the height direction of the vehicle 100, not only can the inlet pipe 50 and outlet pipe 60 be effectively protected, preventing the risk of abnormal cooling caused by road stones or extreme environments damaging the inlet pipe 50 or outlet pipe 60, but it also makes full use of vertical space, making the overall layout more reasonable and compact.

[0046] like Figure 2 and Figure 5As shown, in one embodiment, a sealing plate 211 is installed on the side wall 21, and the sealing plate 211 is connected and communicates with the cooling pipe 40. The sealing plate 211 has a first water inlet connector 2111 and a first water outlet connector 2112, which are disposed through the side wall 21. The first water inlet connector 2111 communicates with the drain end 51, and the first water outlet connector 2112 communicates with the water inlet end 61. By separately providing a sealing plate with the first water inlet connector 2111 and the first water outlet connector 2112, the sealing plate 211 can be replaced individually when it malfunctions, making maintenance more convenient and faster.

[0047] In this embodiment, the first inlet connector 2111 and the first outlet connector 2112 are rigid connectors. The change of pipeline direction is achieved by the rigid connectors fixed to the sealing plate 211, which makes the pipeline less prone to wear and reduces the frequency of replacement.

[0048] Here, the sealing plate 211 also has a second water inlet connector 2113 and a second water outlet connector 2114. The second water inlet connector 2113 is connected to the first water inlet connector 2111, and the second water outlet connector 2114 is connected to the first water outlet connector 2112. The cooling pipe 40 includes a cooling inlet pipe 41 and a cooling outlet pipe 42. The cooling inlet pipe 41 and the cooling outlet pipe 42 are respectively connected to the vehicle power supply 30. The cooling inlet pipe 41 is inserted into and connected to the second water inlet connector 2113, and the cooling outlet pipe 42 is inserted into and connected to the second water outlet connector 2114.

[0049] In this embodiment, the cooling inlet pipe 41 and the cooling outlet pipe 42 are connected to the second water inlet connector 2113 and the second water outlet connector 2114 respectively by means of clamp connection.

[0050] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, a sealing groove through hole 212 is provided on the side wall 21, and the first water inlet connector 2111 and the first water outlet connector 2112 are provided through the sealing groove through hole 212; wherein, the sealing plate 211 is attached to the side wall 21 and connected and sealed with the side wall 21 to block the sealing groove through hole 212.

[0051] like Figure 2As shown, the inlet pipe 50 is connected to and communicates with a first quick-connect fitting 511 at the drain end 51. The first quick-connect fitting 511 is inserted and communicates with the first inlet fitting 2111. The outlet pipe 60 is connected to and communicates with a second quick-connect fitting 611 at the inlet end 61. The second quick-connect fitting 611 is inserted and communicates with the first outlet fitting 2112. In this way, the inlet pipe 50 is connected to the first outlet fitting 2112 through the insertion and communication between the first quick-connect fitting 511 and the first outlet fitting 2112, and the outlet pipe 60 is connected to the second outlet fitting 2114 through the insertion and communication between the second quick-connect fitting 611 and the second outlet fitting 2114. This facilitates the assembly and connection of the inlet pipe 50, the outlet pipe 60 and the sealing plate 211, and improves assembly efficiency.

[0052] In one embodiment, the vehicle 100 further includes an electric drive 70, and the water outlet pipe 60 is connected to and communicates with the electric drive 70.

[0053] like Figure 3 As shown, the vehicle 100 also includes a reduction gear shaft (not shown), which extends along the width of the vehicle 100; wherein, the electric drive 70 is disposed on the side of the reduction gear shaft facing the subframe rear crossbeam assembly 10. By placing the electric drive 70 close to the subframe rear crossbeam assembly 10, the layout around the electric drive 70 is made more compact. Since the electric drive 70 is located in the rear seat area of ​​the vehicle 100, placing the electric drive 70 close to the subframe rear crossbeam assembly 10 allows for greater legroom in the rear seats.

[0054] The following describes the cooling water circulation loop in the automobile 100 provided in this application:

[0055] Cooling water flows out from the radiator (not shown) and enters the inlet pipe 50. It then enters the first inlet connector 2111 through the first quick-connect connector 511, and then flows into the cooling inlet pipe 41 through the second inlet connector 2113. It enters the vehicle power supply 30 to cool the vehicle power supply 30, and then flows out to the cooling outlet pipe 42. After that, it enters the second outlet connector 2114 and then flows through the first outlet connector 2112. It then flows out to the outlet pipe 60 through the second quick-connect connector 611, and finally flows back to the radiator after passing through the electric drive 70.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
