[0011] In one embodiment, each fin unit further includes at least one connecting bar and a plurality of fins, and the plurality of fins are fixedly connected to the connecting bar.

[0012] In one embodiment, each fin is provided with at least one air flow hole; the air flow holes on adjacent fins are connected to each other to form at least one air flow channel between the supporting plate and the heat exchange plate; wherein the air flow channel has an air flow inlet and an air flow outlet, the air flow inlet is suitable for communicating with the external environment and / or the passenger compartment, and the air flow outlet is suitable for communicating with the passenger compartment.

[0056] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] In this application, the directional term "vertical" refers to the direction generally along the height of the vehicle; the directional term "downward" refers to the direction generally pointing to the ground along the vertical direction; the directional term "upward" refers to the direction generally away from the ground along the vertical direction, which is opposite to the direction indicated by "downward".

[0058] Figure 1 A vehicle 1 according to an embodiment of the present application is schematically shown. Figure 1 As shown, the vehicle 1 includes a passenger compartment 11, a frame 10 (such as Figure 3As shown) and a box 12 for accommodating a battery module 13. The passenger compartment 11 includes a floor assembly 2, which is arranged on the frame 10, and the passenger compartment 11 is located above the frame 10 as a whole (as shown). Figure 2 (As shown). The housing 12 is also mounted on the vehicle frame 10 and is located below the floor assembly 2. In other embodiments, the floor assembly 2 and / or the housing 12 may also be part of the vehicle frame 10. The battery module 13 is well known to those skilled in the art and will not be described in detail here.

[0059] Next, the floor assembly 2 of the first embodiment will be described.

[0060] like Figure 4 As shown, the base plate assembly 2 includes a heat exchange plate 3 , a support layer 4 arranged on the upper surface 31 of the heat exchange plate 3 , and a cover layer 5 laid on the support layer 4 .

[0061] The heat exchange plate 3 is assembled with the box body 12. The heat exchange plate 3 has an upper surface 31 facing the passenger compartment 11, and a heat exchange medium channel 32 is provided on the upper surface 31. The heat exchange medium channel 32 protrudes from the upper surface 31 of the heat exchange plate 3 toward the passenger compartment 11 by a first height H1 (e.g. Figure 6 As shown). From the overall point of view, the upper surface 31 of the heat exchange plate 3 is uneven. The number of heat exchange medium channels can be one or more. Figure 4 A heat exchange medium channel 32 is schematically shown in FIG.

[0062] Also like Figure 4 As shown, the support layer 4 includes a plurality of fin units 41. Figure 7 As shown, these fin units 41 are fixedly arranged on the upper surface 31 of the heat exchange plate 3 and deviate from the heat exchange medium channel 32. In one embodiment, these fin units 41 protrude from the upper surface 31 of the heat exchange plate 3 toward the passenger compartment 11 by a second height H2, and the second height H2 is greater than the first height H1 (as shown in FIG. Figure 6 shown).

[0063] In one embodiment, a supporting plate 42 is provided on the fin units 41. That is, the supporting plate 42 is supported by the fin units 41. Thus, the supporting plate 42 is spaced apart from the heat exchange medium passage 32 in the vertical direction H.

[0064] The cover layer 5 is laid on the support plate 42 and forms at least a portion of the bottom wall of the passenger compartment 11 (i.e., the floor of the passenger compartment 11). In one embodiment, the cover layer 5 is a carpet for passengers to walk on. The cover layer 5 also serves as an insulation layer for the battery module 13, thereby improving the thermal insulation effect of the battery module 13.

[0065] In the vehicle 1 of the present application, the heat exchange plate 3 of the floor assembly 2 is assembled with the box 12 that accommodates the battery module 13. Therefore, when it is necessary to dissipate heat from the battery module 13 (for example, in summer), cold heat exchanger can be supplied to the heat exchanger channel 32 on the heat exchanger plate 3; when it is necessary to heat the battery module 13 (for example, in winter), hot heat exchanger can be supplied to the heat exchanger channel 32. In this way, heat dissipation or heating of the battery module 13 is achieved as needed. In one embodiment, the heat exchanger can be a fluid such as water or Freon. The vehicle 1 is also equipped with a drive assembly (not shown in the figure) that drives the flow of the heat exchanger, which is well known to those skilled in the art and will not be described in detail here.

[0066] Because the heat exchange plate 3 is part of the floor assembly 2, while the heat exchanger dissipates heat or heats the battery module 13, it also exchanges heat with the air within the passenger compartment 11, thereby cooling or heating the passenger compartment 11. This improves the efficiency of the heat exchanger, speeding up the cooling and / or heating of the passenger compartment 11, and thus enhancing the passenger experience.

[0067] Overall, the battery module 13 and the passenger compartment 11 share the floor assembly 2 (or heat exchange plate 3 ) with heat exchange function, which reduces the number of components of the vehicle 1 and reduces the cost of the vehicle 1 .

[0068] Moreover, since the protruding height of the fin unit 41 on the upper surface 31 of the heat exchange plate 3 is greater than the protruding height of the heat exchanger channel 32, the support plate 42 is separated from the heat exchanger channel 32 along the vertical direction H. Therefore, when the occupant steps on the cover layer 5, the pressure from the occupant will act on the fin unit 41 and the support plate 42, and the heat exchanger channel 32 will not directly bear the pressure from the occupant. This prevents the heat exchanger channel 32 from being crushed. In one embodiment, the protruding height of the fin unit 41 is between 8mm and 10mm, while the protruding height of the heat exchanger channel 32 is between 4mm and 5mm. Of course, according to actual conditions, the fin unit 41 can also be set to other protruding heights, and the same is true for the heat exchanger channel 32, which will not be repeated here.

[0069] In addition, the support plate 42 separates the cover layer 5 from the fin unit 41 and the heat exchanger channel 32 on the heat exchange plate 3. When the occupant steps on the cover layer 5, the cover layer 5 will not become uneven due to the fin unit 41 and / or the heat exchanger channel 32, so the occupant will not feel the unevenness of the bottom plate assembly 2 of the passenger compartment 11, thereby further improving the occupant's riding experience. In one embodiment, the support plate 42 is a steel plate, and the thickness can be 0.5 mm. Of course, depending on the actual situation, the support plate 42 can also be made of other materials (for example, aluminum alloy), and the thickness can also be other values. It should be noted that the stiffness and strength of the heat exchange plate 3 are greater than the stiffness and strength of the support plate 42, and it serves as the main force-bearing member of the bottom plate assembly 2.

[0070] The covering layer 5 does not contact the fin units 41, thus preventing the fin units 41 from damaging the covering layer 5. Of course, the covering layer 5 can also be laid directly on the fin units 41 without providing the supporting plates 42 on the fin units 41 according to actual requirements.

[0071] In one embodiment, the top of the housing 12 is formed with an opening, and the heat exchange plate 3 is adapted to cover the opening. Thus, the heat exchange plate 3 and the housing 12 together form a housing that houses the battery module 13, and the heat exchange plate 3 serves as the top cover of this housing. In other words, the heat exchange plate 3 not only serves as the primary force-bearing component of the floor assembly 2 but also as the top cover of the housing. This reduces the number of parts in the vehicle 1 and thus the cost of the vehicle 1.

[0072] In one embodiment, the lower surface of the heat exchange plate 3 facing the battery module 13 is flat. This allows the heat exchange plate 3 to maintain close contact with the battery module 13, improving heat transfer between the heat exchange plate 3 and the battery module 13. Optionally, thermally conductive adhesive may be applied between the heat exchange plate 3 and the battery module 13 to further improve heat transfer between the heat exchange plate 3 and the battery module 13. Thermally conductive adhesives are well known to those skilled in the art and will not be described in detail here.

[0073] like Figure 7 As shown, the plurality of fin units 41 are independent of each other, which facilitates individual maintenance and / or replacement of each fin unit 41. Figure 8As shown, each fin unit 41 includes two connecting bars (i.e., a first connecting bar 412a and a second connecting bar 412b) and a plurality of fins 411. The first connecting bar 412a and the second connecting bar 412b extend in parallel and are spaced apart, and the fins 411 are connected between the first connecting bar 412a and the second connecting bar 412b. For example, the fins 411, the first connecting bar 412a, and the second connecting bar 412b are all metal parts (e.g., made of aluminum alloy or steel), so that the fins 411 are welded to the first connecting bar 412a and the second connecting bar 412b. In this way, both ends of the fins 411 of each fin unit 41 are fixed, thereby improving the stability of the fins 411.

[0074] Also like Figure 4 As shown, the heat exchanger channel 32 includes a plurality of channel sections 321. A receiving space 322 exists around each channel section 321. For example, a receiving space 322 exists on at least one side of each channel section 321 in the transverse direction (the "transverse direction" mentioned here refers to a direction substantially perpendicular to the extending direction of the channel section 321). Each fin unit 41 is respectively disposed in a corresponding receiving space 322 (e.g., Figure 7 As shown in the figure, the dimensions of the corresponding fin units can be adjusted according to the size of each receiving space, ensuring a better fit between the fin units and the corresponding receiving space. Overall, the fin units 41 fill the area of ​​the upper surface 31 of the heat exchange plate 3, excluding the heat exchanger channels 32. This further improves the support provided by the fin units 41 to the support plate 42 and prevents deformation of the support plate 42 and the cover layer 5 when a passenger steps on it. In one embodiment, both the fins 411 and the connecting strips 412 can contact the support plate 42 to provide support.

[0075] For the fin units 41 disposed within the receiving space 322 between two adjacent channel segments 321, the two connecting bars 412 respectively contact the corresponding channel segment 321. In other words, the two channel segments 321 serve as position limits for the fin units 41 disposed in the middle, ensuring that these fin units 41 are more stably positioned on the heat exchange plate 3. In one embodiment, each fin unit 41 is secured to the heat exchange plate 3 by welding its first and second connecting bars 412a, 412b, and / or fins 4111 to the heat exchange plate 3.

[0076] In other embodiments, each fin unit 41 may also have a connecting bar 412, and the fins 411 of the same fin unit 41 are all connected to the connecting bar 412. Details will not be repeated here.

[0077] Also like Figure 8As shown, each fin 411 is formed with a plurality of airflow holes 414. The airflow holes 414 on adjacent fins 411 of the same fin unit 41 are connected to each other. In this way, a plurality of airflow channels 403 (such as Figure 7 As shown). Each air flow channel 403 has an air flow inlet 401 and an air flow outlet 402. The air flow inlet 401 is suitable for communicating with the external environment and / or the passenger compartment 11, and the air flow outlet 402 is suitable for communicating with the passenger compartment 11. When a cold heat exchanger or a hot heat exchanger is supplied into the heat exchanger flow channel 32, the fin unit 41 will be cooled or heated. In this way, after the air flow flows into the air flow channel 403 from the air flow inlet 401, the air flow exchanges heat with the fin unit 41 (i.e., the fins 411 and / or the connecting strips 412), so that the air flow is also cooled or heated. As a result, the air flow flowing from the air flow outlet 402 into the passenger compartment 11 becomes a cold air flow or a warm air flow, which can increase the cooling rate or the heating rate of the passenger compartment 11, which further improves the riding experience of the passengers.

[0078] Also like Figure 8 As shown, each fin 411 is also provided with a plurality of guide plates 413. These guide plates correspond to corresponding airflow holes 414, and along the direction from the airflow inlet 401 to the airflow outlet 402, each airflow hole 414 is located downstream of the corresponding airflow hole 414. Each guide plate 413 is also angled with the airflow direction D. Thus, after the airflow passes through each airflow hole 414, it is deflected under the guidance of the corresponding guide plate 413. Overall, the airflow will flow in a zigzag manner within the airflow channel 403, thereby fully exchanging heat with the fins 411 and / or connecting strips 412, thereby achieving sufficient cooling or heating of the airflow as it flows through the airflow channel 403.

[0079] In one embodiment, each fin 411 may be provided with only one airflow hole 414 and one guide plate 413. The guide plate 413 corresponds to the airflow hole 414 and is located downstream of the airflow hole 414 along the direction from the airflow inlet 401 to the airflow outlet 402. The guide plate 413 also forms an angle with the airflow direction D.

[0080] like Figure 5 、 Figure 7 and Figure 9 As shown, a fan 404 can also be provided at the air inlet 401. The fan 404 is used to drive the air flow into the air flow channel 403. The number of fans 404 can be determined according to actual conditions, for example, one or two, which is not limited here. In one embodiment, the exhaust pipe 405 of the fan 404 can be constructed as a narrow and long shape (such as Figure 12 ), to be connected to the air flow inlets of multiple air flow channels, which helps to reduce the number of fans 404.

[0081] like Figure 5 、 Figure 7 and Figure 10 As shown, an air duct 406 may be provided at the air outlet 402. The air duct 406 has an air inlet 407 communicating with the air outlet 402 of the air flow channel 403 and an air outlet 408 communicating with the passenger compartment 11. In this way, the air flow can enter the passenger compartment 11 under the guidance of the air duct 406. In one embodiment, the air duct 406 may be configured in a long and narrow shape (e.g., Figure 4 and Figure 7 As shown), the air flow outlets 402 of the plurality of air flow channels are connected together, which helps to reduce the number of air guide ducts 406.

[0082] Optionally, a grille 409 (e.g., Figure 11 as shown), to prevent foreign matter from entering the air duct 406 and / or the air flow channel 403.

[0083] In one embodiment, the airflow channel 403 extends substantially along the longitudinal direction L of the vehicle 1 , with the airflow inlet 401 near the front of the vehicle and the airflow outlet 402 near the rear of the vehicle. In one embodiment, the fan 404 may be disposed in the front cabin 14 of the vehicle 1 rather than in the passenger compartment 11 .

[0084] In one embodiment, a sealing adhesive (not shown) is provided between the heat exchange plate 3 and the supporting plate 42 along the circumferential edge of the heat exchange plate 3 to seal and bond the heat exchange plate 3 and the supporting plate 42 together.

[0085] Next, a floor assembly 2 according to a second embodiment will be described.

[0086] Figure 13 The bottom plate assembly 2 of the second embodiment is schematically shown. Figure 13 As shown, the base plate assembly 2 of the second embodiment also includes heat exchange plates 3, a support layer 4 fixedly disposed on the upper surface 31 of the heat exchange plates 3, and a cover layer 5 laid on the support layer 4. The heat exchange plates 3 and cover layer 5 are identical to those of the base plate assembly 2 of the first embodiment and are not described in detail here. For simplicity, only the support layer 4 of the base plate assembly 2 of the second embodiment will be described below.

[0087] like Figure 13 and Figure 14 As shown, the support layer 4 includes a porous plate 43. After the porous plate 43 is fixed to the upper surface 31 of the heat exchange plate 3, the rigidity of the whole formed by the heat exchange plate 3 and the porous plate 43 is greater than the rigidity of the heat exchange plate 3 itself, which improves the load-bearing capacity of the bottom plate assembly 2 and prevents the bottom plate assembly 2 from being deformed by stress.

[0088] It should be noted that if Figure 15As shown, the second height H2 of the porous plate 43 protruding from the upper surface 31 of the heat exchange plate 3 (i.e., the thickness of the porous plate 3) is greater than the first height H1 of the heat exchanger channels 32 protruding from the upper surface 31 of the heat exchanger plate 3. Thus, when an occupant steps on the cover layer 5, the pressure from the occupant acts on the porous plate 43, and the heat exchanger channels 32 are not directly subjected to the pressure from the occupant, thereby preventing the heat exchanger channels 32 from being crushed. In one embodiment, the thickness of the porous plate 43 is between 8 mm and 10 mm, while the protrusion height of the heat exchanger channels 32 is between 4 mm and 5 mm. The porous plate 43 of this thickness has a higher rigidity, thereby helping to improve the load-bearing capacity of the base plate assembly 2.

[0089] In one embodiment, the holes on the porous plate 43 can be circular holes, and the diameter of the circular holes can be between 5 mm and 8 mm. In other embodiments, the holes on the porous plate 43 can also be other shapes, such as regular hexagonal holes, which are not limited here.

[0090] The porous plate 43 may be a metal plate (eg, an aluminum alloy plate or a steel plate). In this way, the porous plate 43 may be welded to the upper surface 31 of the heat exchange plate 3 .

[0091] In one embodiment, as described in the first embodiment, a support plate 42 is provided on the surface of the porous plate 43 away from the heat exchange plate 3. The cover layer 5 is laid on the support plate 42, which prevents passengers from feeling the unevenness of the floor assembly 2 of the passenger compartment 11, thereby improving the passenger experience. Of course, the support plate 42 may not be provided on the porous plate 43, and the cover layer 5 may be laid directly on the porous plate 43.

[0092] Also like Figure 13 As shown, the heat exchanger channel 32 includes a plurality of channel sections 321. A receiving space 322 exists around each channel section 321. For example, a receiving space 322 exists on at least one side of each channel section 321 in the transverse direction (the "transverse direction" mentioned here refers to a direction substantially perpendicular to the extending direction of the channel section 321). The porous plate 43 includes a plurality of sub-plates 431. Each sub-plate 431 is arranged in a corresponding receiving space 322 (e.g., Figure 14 As a whole, these sub-plates 431 fill the area of ​​the upper surface 31 of the heat exchange plate 3, excluding the heat exchange medium channels 32. For a sub-plate disposed within the receiving space 322 between two adjacent channel segments 321, the two channel segments 321 act as a position limiter for the sub-plate, ensuring that the sub-plate is stably positioned on the heat exchange plate 3.

[0093] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
