[0005] In view of this, this application provides a heated / cooled box and vehicle with good sealing performance.

[0006] To solve the above-mentioned technical problems, the first aspect of this application provides a hot and cold box, which includes a box body, a box lid, and a sealing element;

[0007] The box has an internal cavity, one side of which has an opening, and the lid is closable and connectable to the box.

[0008] The sealing element is connected to the box cover and fills the gap between the box cover and the box body when the box cover closes the opening, so as to prevent the gas in the containment cavity from flowing with the gas in the outside.

[0009] The sealing element is an elastic component and has a gas-containing space inside, which is balanced with the external air pressure.

[0010] Optionally, the sealing element has a through hole inside, and the openings on both sides of the through hole abut against the inner wall of the box cover. The inside of the through hole forms the gas containing space, and at least one vent is formed through the inner wall of the through hole. The gas containing space is balanced with the external air pressure through the at least one vent.

[0011] Optionally, the boundary of the orthographic projection of the through hole on the first plane includes a concentric first arc and a second arc, with a gap between the first arc and the second arc, and both arcs curving in the direction of the box.

[0012] The structure corresponding to the second arc abuts against the box body when the box lid closes the opening, and the air hole is provided on the structure corresponding to the second arc.

[0013] Optionally, the seal includes a body and an extension;

[0014] The main body is connected to the box lid, and the extension is located on the side of the main body near the box and is connected to the main body;

[0015] At least a portion of the extension is located within the receiving cavity and abuts against the inner wall of the receiving cavity.

[0016] Optionally, the body is further provided with at least one weight-reducing hole, and the gas in the weight-reducing hole is independent of the gas in the outside.

[0017] Optionally, the lid includes a snap-fit ​​groove, and the seal includes a snap-fit ​​structure, wherein the seal is detachably connected to the snap-fit ​​groove via the snap-fit ​​structure.

[0018] Optionally, the inner wall of the snap-fit ​​groove is provided with a rib, and the rib has a through opening for the snap-fit ​​structure to pass through.

[0020] Optionally, the sealing element is a long strip-shaped component, and the number of the snap-fit ​​structures is multiple, arranged sequentially at intervals along the length direction of the sealing element.

[0021] Optionally, the outer wall of the snap-fit ​​structure includes a slope, the slope being inclined such that the closer it is to the housing, the closer it is to the inner wall of the snap-fit ​​groove.

[0022] A second aspect of this application provides a vehicle that includes the aforementioned refrigerator / heater box.

[0023] The beneficial effects of the technical solutions provided in this application include at least the following:

[0024] The refrigerator / heater box and vehicle provided in this application embodiment have a sealing element on the lid. The sealing element can fill the gap between the lid and the box body when the lid is closed, thus achieving a seal. At the same time, since the gas containment space inside the sealing element is in pressure equilibrium with the outside (the space inside the vehicle's driver's cabin), when the refrigerator / heater box is cooling, the gas in the gas containment space of the sealing element is affected by the cold air, and the gas pressure is lower than that of the outside. At this time, under the influence of atmospheric pressure, some of the outside gas will be forced into the gas containment space, ultimately maintaining pressure equilibrium between the gas containment space and the outside. After the outside gas enters the gas containment space, it will cause the elastic sealing element to expand and deform. Since the size of the gap between the lid and the box body remains unchanged, the expansion of the sealing element makes it fit more tightly with the surface forming the gap, and the sealing performance is naturally better. Compared with refrigerator / heater boxes that are sealed by sealing rings in related technologies, it obviously has better sealing performance. Attached Figure Description

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0037] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. To make the technical solutions and advantages of this application clearer, they will be described in detail below with reference to the accompanying drawings.

[0038] To meet user needs, the vehicle is equipped with a heating / cooling box, which can heat or cool food and / or beverages, keep food warm, preserve food fresh, or lower the temperature of beverages.

[0039] If the airtight seal is poor, hot or cold air inside the airtight compartment will leak into the vehicle, which will have a significant impact on its heating or cooling performance.

[0040] In related technologies, the sealing of the heating and cooling box is generally achieved by setting sealing rings or other sealing components inside the box, but the sealing effect is not good and it is difficult to meet the needs of users.

[0041] In response, this application provides a hot / cold box, such as... Figure 1 and Figure 2 As shown, the hot / cold box may include a box body 1, a box lid 2, and a sealing element 3; the box body 1 has a receiving cavity 11 inside, and one side of the receiving cavity 11 has an opening 111; the box lid 2 is connected to the box body 1 in an openable and closable manner; the sealing element 3 is connected to the box lid 2, and when the box lid 2 closes the opening 111, it fills the gap between the box lid 2 and the box body 1 to prevent the gas in the receiving cavity 11 from flowing with the gas in the outside; wherein, the sealing element 3 is an elastic member, and has a gas receiving space 30 inside, and the gas receiving space 30 is balanced with the outside air pressure.

[0042] In the incubator provided in this application embodiment, a sealing element 3 is provided on the lid 2. The sealing element 3 can fill the gap between the lid 2 and the body 1 when the lid 2 is closed, thus achieving a seal. At the same time, since the gas containing space 30 inside the sealing element 3 is in pressure balance with the outside (the space inside the vehicle's driver's cabin), when the incubator is cooling, the gas in the gas containing space 30 of the sealing element 3 is affected by the cold air, and the gas pressure is lower than that of the outside. At this time, under the influence of atmospheric pressure, some of the outside gas will be forced into the gas containing space 30, ultimately maintaining the pressure balance between the gas containing space 30 and the outside. After the outside gas enters the gas containing space 30, it will cause the elastic sealing element 3 to expand and deform. Since the size of the gap between the lid 2 and the body 1 remains unchanged, the sealing element 3 expands and becomes larger, thus fitting more tightly with the surface forming the gap, and the sealing performance is naturally better. Compared with incubators that are sealed by sealing rings in related technologies, it obviously has better sealing performance.

[0043] It should be noted that since the sealing element 3 has a gas-containing space 30 inside and is balanced with the external air pressure, when the box cover 2 is closed, that is, when the box cover 2 is pressed down, a certain downward pressure will also be generated on the sealing element 3. The gas inside the sealing element 3 can flow to the outside, making the deformation of the sealing element 3 greater. Therefore, the box cover 2 can be closed more smoothly.

[0044] In one embodiment, the seal 3 may have a hollow space inside, and at least one vent 311 may be provided on the peripheral wall surrounding the hollow space. The gas inside the hollow space communicates with the gas outside the seal 3 through the at least one vent 311, and the hollow space is in pressure equilibrium with the outside air. That is, the hollow space at this time is the gas-containing space 30 mentioned above. When the refrigerator / heater is cooling, under the influence of atmospheric pressure, some of the outside gas will be forced into the hollow space through the vent 311. The elastic seal 3 expands and deforms, and the tighter it fits against the box body 1, the better the sealing performance.

[0045] Optionally, those skilled in the art can select and adjust the number and shape of the vent holes 311 according to actual needs.

[0046] However, setting a hollow space inside the elastic seal 3 is very difficult to manufacture and will also result in higher production costs.

[0047] In some embodiments of this application, the cover 2 may include a snap-fit ​​groove 21, and the seal 3 includes a snap-fit ​​structure 34, wherein the seal 3 is detachably connected to the snap-fit ​​groove 21 via the snap-fit ​​structure 34.

[0048] The seal 3 is detachably connected to the snap-fit ​​groove 21, which allows for easy disassembly and assembly when the seal 3 is damaged or needs cleaning, making it convenient for users to operate.

[0049] In another embodiment of this application, such as Figure 3 As shown, a through hole 31 is provided inside the sealing element 3. The openings on both sides of the through hole 31 abut against the inner wall of the box cover 2. A gas containing space 30 is formed inside the through hole 31. At least one air hole 311 is provided through the inner wall of the through hole 31. The gas containing space 30 is balanced with the external air pressure through at least one air hole 311.

[0050] In this embodiment, to form a gas-containing space 30 inside the seal 3, the seal 3 can be made through. The openings 111 on both sides of the through hole 31 abut against the inner wall of the snap-fit ​​groove 21 on the cover 2. Since the seal 3 is elastic, it is sealed with the inner wall of the snap-fit ​​groove 21 under the action of elastic force. Therefore, the manufacturing process of the seal 3 is simpler and the cost is lower. In addition, the gas inside the through hole 31 can communicate with the outside gas through at least one vent 311 and achieve gas pressure balance. When the hot and cold box is cooling, some of the outside gas will be forced into the gas-containing space 30 inside the through hole 31 through at least one vent 311. The elastic seal 3 expands and deforms, and fits more tightly with the box body 1, resulting in better sealing.

[0051] Optionally, those skilled in the art can select and adjust the number and shape of the pores 311 according to actual needs.

[0052] In some embodiments of this application, such as Figure 3 As shown, the boundary of the orthographic projection of the through hole 31 on the first plane includes a concentric first arc 312 and a second arc 313. There is a gap between the first arc 312 and the second arc 313, and the bending direction is towards the box body 1. The structure corresponding to the second arc 313 abuts against the box body 1 when the box cover 2 closes the opening 111, and an air hole 311 is provided on the structure corresponding to the second arc 313.

[0053] As shown in the figure, the structure corresponding to the second arc 313 is an arc-shaped structure and abuts against the box 1 through the arc surface. If the elastic seal 3 is to deform in a set direction when inflated, that is, when deformed, the contact point between the structure corresponding to the second arc 313 and the box 1 deforms along the diameter direction of the arc, thus defining the shape of the through hole 31, that is, the shape of the first arc 312 and the second arc 313.

[0054] When the cooler / warmer is cooling, under the influence of atmospheric pressure, some of the outside gas will be forced into the gas-containing space 30 through at least one vent 311. The structure corresponding to the second arc 313 in the elastic seal 3 will expand and deform in the set direction. The original contact point will deform along the diameter of the arc and move further away from the center of the second arc 313. Then the structure corresponding to the second arc 313 will fit more tightly with the box body 1, further improving the sealing performance of the cooler / warmer.

[0055] It should be noted that currently, users' needs for cooler / warmer boxes are not only for keeping beverages, fruits and vegetables, and frozen products fresh or refrigerated, but also for keeping beverages and food warm or heating them.

[0056] In heated applications, the heat source inside the incubator generates heat, causing the air inside to expand. If the seal is poor, the hot air will escape from the incubator, significantly reducing its insulation and heating performance.

[0057] In some embodiments of this application, such as Figure 3 As shown, the sealing element 3 may include a body 32 and an extension 33; the body 32 is connected to the cover 2, and the extension 33 is located on the side of the body 32 near the box 1 and is connected to the body 32; wherein, at least a portion of the extension 33 is located in the receiving cavity 11 and abuts against the inner wall of the receiving cavity 11.

[0058] In the heating and cooling box provided in this application embodiment, the main body 32 may also be provided with an extension 33. One end of the extension 33 is connected to the main body 32, and the other end extends into the receiving cavity 11 inside the box body 1 and abuts against the box body 1. When the heating and cooling box is heating, the gas in the gas receiving space 30 of the sealing member 3 is affected by the hot air, and the gas pressure is higher than that of the outside. At this time, under the influence of atmospheric pressure, some of the gas in the gas receiving space 30 will flow to the outside, and finally the gas receiving space 30 and the outside will maintain a pressure balance. After the gas in the gas receiving space 30 flows to the outside, the elastic sealing member 3 will be squeezed and deformed, and the entire elastic member will have a downward tendency. Under the action of downward pressure, the extension 33 will fit more tightly with the box body 1, and the sealing performance will naturally be better.

[0059] Therefore, the cooling and heating box provided in this application embodiment, with its sealing member 3 having a gas-containing space 30 and an extension 33, can provide better sealing performance for both cooling and heating. Compared with cooling and heating boxes that are sealed by sealing rings in related technologies, it has better applicability and can meet the sealing needs of users in various usage scenarios.

[0060] In some embodiments, the extension 33 can be an elastic member. When the heating box is heating, the extension 33 is subjected to downward pressure and abuts against the box body 1. At the same time, due to its own elastic force, the abutting force against the box body 1 will be greater and the abutting will be tighter, which can further improve the sealing performance.

[0061] Optionally, the body 32 and the extension 33 can be integrally molded components.

[0062] In some embodiments, both the body 32 and the extension 33 can be elongated components. The body 32 is arranged along the length direction of the snap-fit ​​groove 21 and snaps into the snap-fit ​​groove 21. Since the extension 33 is an elongated component, the contact area with the housing 1 is increased, which can improve the sealing performance.

[0063] In some embodiments of this application, at least one weight-reducing hole 321 is also provided on the body 32, and the gas in the weight-reducing hole 321 is independent of the gas in the outside.

[0064] For insulated and heated boxes, a sealing element 3 needs to be installed. To ensure a good seal, its thickness cannot be too thin, otherwise it will affect the insulation effect. Therefore, the weight of sealing element 3 will be relatively high. For car manufacturers, reducing the overall weight of a vehicle requires optimization of many parts.

[0065] Therefore, in the heating and cooling box provided in this application embodiment, at least one weight-reducing hole 321 can be provided on the sealing member 3 to reduce the weight of the sealing member 3 as much as possible. Furthermore, the two openings 111 on both sides of the weight-reducing hole 321 abut against the inner wall of the snap-fit ​​groove 21, that is, the gas in the weight-reducing hole 321 is not connected with the outside gas. While reducing the weight, it will not affect the sealing effect of the heating and cooling box.

[0066] Optionally, those skilled in the art can select and adjust the number and shape of the weight reduction holes 321 according to the actual weight reduction needs.

[0067] like Figure 3 As shown, in some embodiments, a groove can be formed on the inner side of the seal 3. When the seal 3 is snapped into the snap-fit ​​groove 21, the opening 111 of the groove just abuts against the inner wall of the snap-fit ​​groove 21, thus forming a space. At this time, the groove can be regarded as the weight-reducing hole 321 mentioned above, which has a weight-reducing effect. Moreover, the gas in this space is not connected with the outside gas and will not affect the sealing performance of the seal 3.

[0068] In some embodiments of this application, such as Figure 3As shown, a rib 211 may be provided on the inner side wall of the snap-fit ​​groove 21, and a through opening 2111 for the snap-fit ​​structure 34 to pass through is provided on the rib 211; the dimension of the through opening 2111 in the length direction of the housing 1 is smaller than the dimension of the snap-fit ​​structure 34 in the length direction.

[0069] When it is necessary to install the seal 3, force can be applied to the snap-fit ​​structure 34 on the seal 3. Although the size of the snap-fit ​​structure 34 is smaller than the size of the through-hole 2111, the seal 3 itself is an elastic component. When the snap-fit ​​structure 34 deforms and shrinks, it can smoothly pass through the through-hole 2111, and then expand and enlarge, locking into the through-hole 2111, thus achieving the snap-fit ​​connection between the seal 3 and the snap-fit ​​groove 21. When it is necessary to remove the seal 3, it is only necessary to reverse the operation, which will not be described in detail here.

[0070] In some embodiments of this application, the sealing element 3 can be a long strip-shaped component, and the number of snap-fit ​​structures 34 can be multiple, arranged sequentially at intervals along the length direction of the sealing element 3.

[0071] The sealing element 3 has multiple snap-fit ​​structures 34. These multiple snap-fit ​​structures 34 are connected to the snap-fit ​​groove 21, which can improve the connection strength between the two and prevent the sealing element 3 from accidentally falling off when the lid 2 of the hot and cold box is opened and closed.

[0072] In some embodiments of this application, such as Figure 3 As shown, the outer wall of the snap-fit ​​structure 34 includes an inclined surface 341, which is inclined such that the closer it is to the housing 1, the closer it is to the inner wall of the snap-fit ​​groove 21.

[0073] By providing a bevel 341 on the snap-fit ​​structure 34, the seal 3 can pass through the passage 2111 more smoothly without excessive compression of the snap-fit ​​structure 34. The bevel 341 acts as a guide. This arrangement makes it easier to connect the seal 3 with the snap-fit ​​groove 21 and is less likely to damage the snap-fit ​​structure 34.

[0074] In some embodiments, an insulation layer may be laid on the inner wall of the box 1 to further improve the insulation performance of the hot and cold box.

[0075] In some embodiments, such as Figure 4 and Figure 5As shown, a button can be provided on both the left and right sides of the lid 2, namely the driver's side button 100 and the passenger side button 200. The interior of the box 1 has a first opening / closing mechanism on the driver's side and a second opening / closing mechanism on the passenger side. When the user needs to open the refrigerator / heater box from the driver's side, they can press the driver's side button 100. At this time, the first opening / closing mechanism on the driver's side button 100 is locked, and the lid 2 can rotate around the axis of the second opening / closing mechanism to open the receiving cavity 11. When the user needs to open the refrigerator / heater box from the passenger side, they can press the passenger side button 200. At this time, the second opening / closing mechanism on the passenger side button 200 is locked, and the lid 2 can rotate around the axis of the first opening / closing mechanism to open the receiving cavity 11.

[0076] This application also provides a vehicle that includes the aforementioned refrigerator / heater box.

[0077] In the vehicle provided in this application embodiment, a sealing element 3 is provided on the lid 2 of the refrigerator / heater compartment. The sealing element 3 can fill the gap between the lid 2 and the compartment 1 when the lid 2 is closed, thus achieving a seal. At the same time, since the gas containing space 30 inside the sealing element 3 is in pressure balance with the outside (the space inside the vehicle's driver's cabin), when the refrigerator / heater compartment is cooling, the gas in the gas containing space 30 of the sealing element 3 is affected by the cold air, and the gas pressure is lower than that of the outside. At this time, under the influence of atmospheric pressure, some of the outside gas will be forced into the gas containing space 30, ultimately maintaining the pressure balance between the gas containing space 30 and the outside. After the outside gas enters the gas containing space 30, it will cause the elastic sealing element 3 to expand and deform. Since the size of the gap between the lid 2 and the compartment 1 remains unchanged, the sealing element 3 expands and becomes larger, thus fitting more tightly with the surface forming the gap, and the sealing performance is naturally better. Compared with refrigerators / heater compartments that are sealed by sealing rings in related technologies, it obviously has better sealing performance.

[0078] In addition, thanks to the aforementioned heating and cooling boxes, the sealing requirements of users in different heating and cooling box usage scenarios can be met, making it more adaptable and providing users with a better user experience.

[0079] In some embodiments, the hot / cold compartment can be embedded in the armrest compartment (the part between the driver's seat and the passenger seat), and the armrest can be installed on the outside of the compartment cover 2 and rotatably connected to the compartment body 1 through a connector, so as to realize the integration of the armrest and the compartment cover 2.

[0080] Alternatively, the connector can be a pin.

[0081] In other embodiments, the heating / cooling box can be located behind the rear seat of the vehicle, with the lid integrated into the portion between the two rear seats. Opening and closing this portion allows the opening and closing of the containment cavity within the heating / cooling box.

[0082] It should be noted that the heating and cooling box can also be installed in other places inside the vehicle, such as in front of the passenger seat. Those skilled in the art can select and adjust it according to actual needs.

[0083] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0084] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only.

[0085] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
