[0045] Please refer to Figures 1 to 5 As shown, the vehicle provided by the embodiments of this application includes a trunk 100 and an in-vehicle refrigeration device 200. The trunk 100 includes a storage box 101 and a sunken box 102 provided on the lower side of the storage box 101. The in-vehicle refrigeration device 200 includes a refrigeration box body 201 and a refrigeration component 202. The refrigeration box body 201 is provided inside the sunken box 102; a refrigeration chamber 2011 and an electrical chamber 2012 are provided inside the refrigeration box body 201. The refrigeration component 202 is provided in the electrical chamber 2012, and the refrigeration component 202 is used to refrigerate the refrigeration chamber 2011. The refrigeration component 202 includes a radiator 2024. A first air outlet 2012a is provided on the box wall where the electrical chamber 2012 is located, and the first air outlet 2012a communicates the radiator 2024 and the external space of the vehicle.

[0046] In the vehicle provided by the embodiments of this application, the refrigeration box body 201 in the in-vehicle refrigeration device 200 is provided inside the sunken box 102 of the trunk 100 of the vehicle. A first air outlet 2012a is provided on the box wall where the electrical chamber 2012 in the refrigeration box body 201 is located. The first air outlet 2012a communicates the radiator 2024 in the refrigeration component 202 and the external space of the vehicle. During the process of the refrigeration device 200 refrigerating the refrigeration chamber 2011, the radiator 2024 dissipates heat from the refrigeration device 200, and guides the high-temperature waste heat to the external space of the vehicle through the first air outlet 2012a, replacing the existing solution of guiding the high-temperature waste heat to the vehicle cabin, greatly improving the air quality and temperature comfort in the vehicle cabin space, and thus improving the user experience of the vehicle.

[0047] Among them, the refrigeration component 202 includes but is not limited to an evaporator 2021, a condenser 2022, a compressor 2023, a radiator 2024, a throttle valve 2025, etc. The component composition and working principle of the refrigeration component 202 belong to the prior art. All components of the refrigeration component 202 are provided in the electrical chamber 2012. The refrigeration of the refrigeration chamber 2011 is completed through the refrigeration component 202, that is, the temperature of the refrigeration chamber 2011 is reduced and maintained at a certain low temperature state. The waste heat generated by the refrigeration component 202 refrigerating the refrigeration chamber 2011 is discharged to the external space of the vehicle through the first air outlet 2012a driven by the radiator 2024.

[0048] In some embodiments, the vehicle includes a sheet metal exterior layer 300, on which a pressure relief valve 500 is provided, and the air outlet is communicated with the pressure relief valve 500.

[0049] Generally, a pressure relief valve 500 is provided on the sheet metal exterior layer 300 of the vehicle. In this embodiment, the existing pressure relief valve 500 on the vehicle is used as the end component for discharging the refrigeration waste heat from the vehicle. The refrigeration waste heat is finally discharged from the vehicle through the pressure relief valve 500, making full use of the existing components of the vehicle without the need to design other end components, thus reducing the cost of implementing the solution of this application.

[0050] In some embodiments, the vehicle further includes an interior layer 400. The interior layer 400 and the sheet metal exterior layer 300 are stacked and a gap 700 is formed therebetween; a part of the interior layer 400 constitutes the wall of the sunken box 102, and a second air outlet 1023a is provided on the wall of the sunken box 102. The first air outlet 2012a, the second air outlet 1023a, the gap 700, and the pressure relief valve 500 are connected in sequence.

[0051] Generally, the interior layer 400 and the sheet metal exterior layer 300 of the vehicle are stacked and a gap 700 is formed therebetween, and the pressure relief valve 500 is provided on the sheet metal exterior layer 300 of the vehicle, that is, the pressure relief valve 500 and the gap 700 are in a connected state. In this embodiment, the existing gap 700 of the vehicle is used as the path for discharging the above-mentioned refrigeration waste heat from the vehicle. On the basis of having the first air outlet 2012a, by providing a second air outlet 1023a on the interior layer 400 that constitutes the wall of the sunken box 102, the first air outlet 2012a and the second air outlet 1023a are connected to conduct the electrical compartment 2012 where the radiator 2024 is located and the above-mentioned gap 700, allowing the radiator 2024 to drive the refrigeration waste heat into the gap 700, using the gap 700 as the path to diffuse and discharge it to the pressure relief valve 500, and finally discharging it to the external space of the vehicle.

[0052] In some embodiments, another part of the interior layer 400 constitutes the wall of the storage box 101. Some walls of the storage box 101 and / or some walls of the sunken box 102 extend along the height direction of the vehicle to form longitudinal walls. Part of the internal space of the trunk 100 and the internal space of the sunken box 102 are arranged on both sides of the longitudinal wall along the width direction of the vehicle. An air intake opening is provided on the longitudinal wall, and an air inlet 2012b is provided on the wall where the electrical compartment 2012 is located. The air intake opening, the air inlet 2012b, and the radiator 2024 are connected in sequence.

[0053] Generally, the trunk 100 of a vehicle is provided with a storage box 101 and a sunken box 102. The sunken box 102 is formed by sinking downward from the bottom of the storage box 101. The box walls of the storage box 101 and the sunken box 102 are both composed of an interior layer 400. One side of the sunken box 102 facing the storage box 101 is provided with an upper opening 1021 and has a bottom wall 1022 opposite to the upper opening 1021. The refrigeration device 200 is arranged in the space between the upper opening 1021 and the bottom wall 1022. A detachable or movable cover plate 800 is provided on the upper opening 1021. The upper opening 1021 is closed or opened through the cover plate 800, thereby closing or opening the sunken box 102.

[0054] Among them, the space in the storage box 101 above the cover plate 800 is the main storage space of the storage box 101. Generally, the items to be stored are placed in the space above the cover plate 800, that is, the space directly above the sunken box 102. Therefore, in order to introduce the cold air in the vehicle cabin into the electrical compartment 2012, so as to make full use of the refrigeration efficiency of the whole vehicle and reduce the refrigeration cost, an air inlet is opened by using the longitudinal wall formed by the upper edge of the interior layer 400 extending along the height direction of the vehicle, and the cold air in the storage box 101 and the cabin is introduced into the electrical compartment 2012 without being affected by the items to be stored directly above the sunken box 102. The refrigerated air in the cabin is introduced through the air inlet, and then enters the electrical compartment 2012 through the air inlet 2012b. The radiator 2024 drives the cold air to enter the first air outlet 2012a from the air inlet 2012b, and takes out the refrigeration waste heat from the electrical compartment 2012.

[0055] In some embodiments, the box wall of the storage box 101 includes a first longitudinal wall 1011 and a second longitudinal wall 1012, and the box wall of the sunken box 102 includes a third longitudinal wall 1023. The first longitudinal wall 1011, the second longitudinal wall 1012 and the third longitudinal wall 1023 are arranged in sequence along the width direction, and the first longitudinal wall 1011 and the second longitudinal wall 1012 are spaced apart to form a first interval area 1013. The internal space of the trunk 100 includes the first interval area 1013. The longitudinal walls include the second longitudinal wall 1012 and the third longitudinal wall 1023. The air inlets include a first air inlet 1012a provided on the second longitudinal wall 1012 and a second air inlet 1023b provided on the third longitudinal wall 1023. The first air inlet 1012a, the second air inlet 1023b, the air inlet 2012b and the radiator 2024 are connected in sequence.

[0056] Generally, the lowest height of the above-mentioned storage box 101 is located between the above-mentioned upper opening 1021 and the above-mentioned bottom wall 1022. Based on the above-mentioned longitudinal wall solution, the box wall formed by the interior layer 400 between the upper opening 1021 and the lowest height of the storage box 101 can be fully utilized, and an air inlet is opened on this part of the box wall.

[0057] Specifically, the first longitudinal wall 1011 and the second longitudinal wall 1012 are arranged in sequence along the width direction, and the first longitudinal wall 1011 and the second longitudinal wall 1012 are spaced apart to form a first spacing area 1013. In this way, the space of the storage box 101 located directly above the sunken box 102 can be communicated with the formed first spacing area 1013, so that the air in the cabin and the storage box 101 enters the first air inlet 1012a through the first spacing area 1013, and then reaches the air inlet 2012b through the second air inlet 1023b provided on the third longitudinal wall 1023, and then enters the electrical compartment 2012.

[0058] In some embodiments, the box wall of the storage box 101 further includes a transverse wall 1014. The transverse wall 1014 is connected between the first longitudinal wall 1011 and the second longitudinal wall 1012. The first spacing area 1013 and the gap 700 are arranged on both sides of the transverse wall 1014 along the height direction. The vehicle further includes a partition wall 600. The second longitudinal wall 1012 and the third longitudinal wall 1023 are spaced apart along the width direction to form a second spacing area 1024. The partition wall 600 is connected between the second longitudinal wall 1012 and the third longitudinal wall 1023. The second spacing area 1024 and the gap 700 are arranged on both sides of the partition wall 600 along the height direction, and the gap 700 is located on the same side of the transverse wall 1014 and the partition wall 600.

[0059] The partition wall 600 blocks the second spacing area 1024 and the gap 700 to prevent them from communicating and reducing the efficiency of the cabin air entering the electrical compartment 2012, thereby increasing the utilization rate of the cabin air.

[0060] In some embodiments, the box wall of the storage box 101 includes two first longitudinal walls 101 and two second longitudinal walls 1012. The box wall of the sunken box 102 includes two third longitudinal walls 1023. The two third longitudinal walls 1023 define the width dimension of the sunken box 102 along the width direction. The above-mentioned cover plate 800, bottom wall 1022 and two third longitudinal walls 1023 define the volume of the sunken box 102, and the refrigeration device 200 is accommodated in this volume.

[0061] Two first longitudinal walls 1011 are located on the outermost sides in the width direction. The distance between the two first longitudinal walls 1011 constitutes the maximum distance of the storage box 101 in the width direction, and the two first longitudinal walls 1011 are connected at the top. Two second longitudinal walls 1012 are located inside the two first longitudinal walls 1011 in the width direction and outside the two third longitudinal walls 1023. One side of the cover plate 800 in the width direction is supported on one second longitudinal wall 1012 and one third longitudinal wall 1023, and the other side is supported on the other second longitudinal wall 1012 and the other third longitudinal wall 1023. Moreover, the cover plate 800 covers and seals the other end opposite to the partition wall 600 in the height direction, so that both sides of the second partition area 1024 in the height direction are sealed. Among them, the dimension of the third longitudinal wall 1023 in the height direction is greater than the dimension of the second longitudinal wall 1012 in the height direction, and the bottoms of the two third longitudinal walls 1023 are connected to the bottom wall 1022 mentioned above.

[0062] The box walls of the storage box 101 include two transverse walls 1014. The two transverse walls 1014 are arranged inside the two first longitudinal walls 1011 in the width direction and outside the two second longitudinal walls 1012. Then, the gaps 700 on the outer sides of the two first longitudinal walls 1011, the lower sides of the two transverse walls 1014, the lower side of the partition wall 600, the outer sides of the two third longitudinal walls 1023, and the lower side of the bottom wall 1022 communicate with each other, and two pressure relief valves 500 are arranged on the sheet metal appearance layer 300 corresponding to the two first longitudinal walls 1011. In this way, the refrigeration waste heat can be discharged through the two pressure relief valves 500.

[0063] Therefore, in some embodiments, two pressure relief valves 500 are arranged on the sheet metal appearance layer 300. The two pressure relief valves 500 are respectively arranged on both sides of the vehicle in the width direction of the vehicle, and the two pressure relief valves 500 communicate through the gap 700.

[0064] In some embodiments, the electrical compartment 2012 and the refrigeration compartment 2011 are arranged in sequence in the width direction. The air inlet 2012b and the first air outlet 2012a are arranged on the box wall of the electrical compartment 2012 facing away from the refrigeration compartment 2011, and the air inlet 2012b and the first air outlet 2012a are arranged in sequence from top to bottom in the height direction.

[0065] The air inlet 2012b and the first air outlet 2012a are arranged in sequence from top to bottom in the height direction, so that the air driven by the radiator 2024 forms an arc-shaped path as Figure 3 shown. The arc-shaped path can increase the flow path of the air in the electrical compartment 2012 and increase the contact area between the air and all components in the electrical compartment 2012, and take away the refrigeration waste heat with the greatest efficiency.

[0066] In some embodiments, the outer contour of the refrigeration box body 201 is adapted to the contour of the wall of the sunken box 102. The first air outlet 2012a and the second air outlet 1023a are arranged opposite to each other, the air induction port and the air inlet 2012b are arranged opposite to each other, and the heat dissipation machine 2024 is coaxially arranged and adjacent to the air inlet 2012b.

[0067] The outer contour of the refrigeration box body 201 is adapted to the contour of the wall of the sunken box 102, that is, the shape of the refrigeration box body 201 can be fully adapted to the shape of the sunken box 102, and all the space of the sunken box 102 can be fully utilized to arrange the refrigeration box body 201, so as to fully increase the volume of the refrigeration box body 201. Furthermore, the volume of the refrigeration compartment 2011 therein can be allowed to be increased, and users can be allowed to store more items to be refrigerated. And on the basis of this design, the first air outlet 2012a and the second air outlet 1023a are arranged opposite to each other, the air induction port and the air inlet 2012b are arranged opposite to each other, and the heat dissipation machine 2024 is coaxially arranged and adjacent to the air inlet 2012b, which can reduce the path for the cabin air to enter the electrical compartment 2012 and reduce the path for the refrigeration waste heat to be discharged from the electrical compartment 2012, reduce the frictional loss on the path, and improve the discharge efficiency of the refrigeration waste heat.

[0068] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
