DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In order to make the technical solutions and advantages of the present application clearer, they will be described in detail in conjunction with the drawings below.

[0038] In order to meet the needs of users, a heating and cooling box is provided on the vehicle, which can realize heating or cooling, so as to keep food and / or drinks warm, keep food fresh, and lower the temperature of drinks, etc.

[0039] For the heating and cooling box, if the sealing is not good, the hot air or cold air inside the heating and cooling box will leak into the interior of the vehicle, which will have a great impact on its heating or cooling effect.

[0040] In the related art, the sealing of the heating and cooling box is generally achieved by providing sealing members such as sealing rings in the heating and cooling box, but the sealing effect is not good and it is difficult to meet user needs.

[0041] In this regard, the present application provides a cold and warm box, such as Figure 1 and Figure 2 As shown, the heating and cooling box may include a box body 1, a box cover 2 and a sealing member 3; the box body 1 has a accommodating chamber 11 inside, and one side of the accommodating chamber 11 has an opening 111, and the box cover 2 is connected to the box body 1 in an openable and closable manner; the sealing member 3 is connected to the box cover 2, and when the box cover 2 closes the opening 111, it fills the gap between the box cover 2 and the box body 1 to prevent the gas in the accommodating chamber 11 from circulating with the external gas; wherein the sealing member 3 is an elastic component, and has a gas accommodating space 30 inside, and the gas accommodating space 30 is balanced with the external air pressure.

[0042] In the heating and cooling box provided in the embodiment of the present application, a seal 3 is provided on the box cover 2, and the seal 3 can fill the gap between the box cover 2 and the box body 1 when the box cover 2 is closed to achieve sealing; at the same time, since the gas containing space 30 inside the seal 3 is in air pressure balance with the outside world (the space in the vehicle cockpit), when the heating and cooling box is cooling, the gas in the gas containing space 30 of the seal 3 is affected by the cold air, and the air pressure is lower than that of the outside world. At this time, under the influence of atmospheric pressure, part of the outside gas will be pressed into the gas containing space 30, and finally the gas containing space 30 maintains air pressure balance with the outside world. After the outside gas enters the gas containing space 30, the elastic seal 3 will expand and deform, while the size of the gap between the box cover 2 and the box body 1 remains unchanged. The larger the seal 3 expands, the tighter it fits with the surface forming the gap, and the better the sealing is. Compared with the heating and cooling box sealed by a sealing ring in the related art, it obviously has better sealing performance.

[0043] It should be noted that since a gas accommodating space 30 is provided inside the seal 3 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 be generated on the seal 3, and the gas in the seal 3 can flow to the outside, making the deformation of the seal 3 larger, so that the box cover 2 can also be closed more smoothly.

[0044] In one embodiment, the seal 3 may have a hollow space inside, and at least one air hole 311 may be provided on the peripheral wall surrounding the hollow space. The gas inside the hollow space is connected to the gas outside the seal 3 through at least one air hole 311, and the hollow space is balanced with the external air pressure. That is, the hollow space at this time is the above-mentioned gas accommodating space 30. When the refrigerator is refrigerated, under the influence of atmospheric pressure, part of the external gas will be pressed into the hollow space through the air hole 311, and the elastic seal 3 will expand and deform, and the tighter it fits with the box body 1, the better the sealing performance will be.

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

[0046] However, providing a hollow space inside the elastic sealing member 3 is very difficult to manufacture and the production cost is also high.

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

[0048] The sealing member 3 is detachably connected to the clamping groove 21 , and can be conveniently disassembled and assembled when the sealing member 3 is damaged or needs to be cleaned, which is convenient for user operation.

[0049] In another embodiment of the present application, Figure 3 As shown, a through hole 31 is formed inside the seal 3, and 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, and at least one air hole 311 is formed on the inner wall of the through hole 31, and the gas containing space 30 is balanced with the external air pressure through at least one air hole 311.

[0050] In this embodiment, if it is desired to form a gas accommodating space 30 inside the seal 3, the seal 3 can be penetrated, and the openings 111 on both sides of the through hole 31 abut against the inner wall of the snap-fit ​​groove 21 on the box cover 2. Since the seal 3 is elastic, it is sealed from the inner wall of the snap-fit ​​groove 21 under the action of elastic force, so the manufacturing process of the seal 3 is simpler and the cost is lower; in addition, the gas inside the through hole 31 can be interconnected with the external gas through at least one air hole 311 and the air pressure is balanced. When the heating and cooling box is cooling, part of the external gas will be pressed into the gas accommodating space 30 inside the through hole 31 through at least one air hole 311, and the elastic seal 3 will expand and deform, and the tighter it fits with the box body 1, the better the sealing performance.

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

[0052] In some embodiments of the present application, 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 directions are both toward 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 the structure corresponding to the second arc 313 is provided with an air hole 311.

[0053] As shown in the figure, the structure corresponding to the second arc 313 is an arc-shaped structure as a whole, and abuts against the box body 1 through the arc-shaped surface. If the elastic seal 3 is to be deformed in a set direction when inflated, that is, the abutment point between the structure corresponding to the second arc 313 and the box body 1 is deformed along the diameter direction of the arc during deformation, the shape of the through hole 31, that is, the shape of the first arc 312 and the second arc 313 is limited.

[0054] When the refrigerator is cooling, under the influence of atmospheric pressure, part of the external gas will be pressed into the gas containing space 30 through at least one air hole 311, and the structure corresponding to the second arc 313 in the elastic seal 3 will expand and deform in the set direction, and the original abutment point will deform along the diameter direction of the arc, and will be further away from the center of the second arc 313. Then, the structure corresponding to the second arc 313 will fit more closely to the box body 1, further improving the sealing of the refrigerator.

[0055] It should be noted that at present, users' demands for cold and warm boxes include not only the need to preserve or refrigerate drinks, fruits and vegetables, frozen products, etc., but also the need to keep drinks and food warm and heat them.

[0056] In the heating scenario, the heat source inside the cold and warm box will generate heat, and the air inside the cold and warm box will expand due to the heat. If the sealing is not good, the hot air will escape from the cold and warm box, causing the insulation and heating performance of the cold and warm box to be greatly reduced.

[0057] In this regard, in some embodiments of the present application, Figure 3 As shown, the seal 3 may include a main body 32 and an extension portion 33; the main body 32 is connected to the box cover 2, and the extension portion 33 is located on a side of the main body 32 close to the box body 1 and is connected to the main body 32; wherein at least a portion of the extension portion 33 is located in the accommodating cavity 11 and abuts against the inner wall of the accommodating cavity 11.

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

[0059] Therefore, in the cold and warm box provided in the embodiment of the present application, the seal 3 is provided with a gas containing space 30 and an extension portion 33, so that the cold and warm box has better sealing performance during both cooling and heating. Compared with the cold and warm box sealed by a sealing ring in the related technology, it has better applicability and can meet the sealing needs of users in various usage scenarios.

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

[0061] Optionally, the body 32 and the extension portion 33 may be an integrally formed component.

[0062] In some embodiments, the main body 32 and the extension portion 33 can both be long strip components. The main body 32 is arranged along the length direction of the snap-in groove 21 and is snap-connected to the snap-in groove 21. Since the extension portion 33 is a long strip component, the contact area with the box body 1 is increased, which can improve the sealing performance.

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

[0064] For the cold and warm boxes, a circle of seals 3 is required. In order to ensure the sealing effect, the thickness of the seals 3 cannot be too low, otherwise the insulation effect will be affected. Therefore, the weight of the seals 3 will be relatively high. For automobile manufacturers, reducing the weight of the entire vehicle requires optimization of many parts.

[0065] Therefore, in the heating and cooling box provided in the embodiment of the present application, at least one weight-reducing hole 321 can be provided on the seal 3 to reduce the weight of the seal 3 as much as possible, and the openings 111 on both sides of the weight-reducing hole 321 are against the inner wall of the clamping groove 21, that is, the gas in the weight-reducing hole 321 is not connected to the external gas, which reduces the weight without affecting the sealing effect of the heating and cooling box.

[0066] Optionally, those skilled in the art may select and adjust the number and shape of the weight reduction holes 321 according to 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 snap-connected with the snap-in groove 21, the opening 111 of the groove just abuts against the inner wall of the snap-in groove 21, thereby enclosing a space. At this time, the groove can be regarded as the above-mentioned weight-reducing hole 321, which has a weight-reducing effect, and the gas in the space is not connected to the external gas, and will not affect the sealing performance of the seal 3.

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

[0069] When the seal 3 needs to be installed, force can be applied to the clamping structure 34 on the seal 3. Although the size of the clamping structure 34 is smaller than the size of the through hole 2111, the seal 3 itself is an elastic component. When the clamping structure 34 is deformed and reduced, it can smoothly pass through the through hole 2111, and then expand and become larger, and clamped at the through hole 2111, so as to realize the clamping connection between the seal 3 and the clamping groove 21. When the seal 3 needs to be removed, only the reverse operation is required, and this application will not elaborate on this.

[0070] In some embodiments of the present application, the sealing member 3 may be a long strip-shaped member, and the number of the clamping structures 34 may be multiple and arranged in sequence and at intervals along the length direction of the sealing member 3 .

[0071] There are multiple snap-fit ​​structures 34 on the seal 3. By snap-fitting the multiple snap-fit ​​structures 34 with the snap-fit ​​grooves 21, the connection strength between the two can be improved, and the seal 3 can be prevented from accidentally falling off when the box cover 2 of the heating and cooling box is opened and closed.

[0072] In some embodiments of the present application, Figure 3 As shown, the outer side wall of the clamping structure 34 includes an inclined surface 341 , and the inclined surface 341 is inclined so that the closer it is to the box body 1 , the closer it is to the inner side wall of the clamping groove 21 .

[0073] By providing a slope 341 on the snap-fit ​​structure 34, the seal 3 can pass through the through-port 2111 more smoothly without over-compressing the snap-fit ​​structure 34. The slope 341 plays a guiding role. This setting can save effort when connecting the seal 3 and the snap-fit ​​groove 21, and is not easy to cause damage to the snap-fit ​​structure 34.

[0074] In some embodiments, a thermal insulation layer may be laid on the inner wall of the box body 1, which can further improve the thermal insulation performance of the cold and warm box.

[0075] In some embodiments, Figure 4 and Figure 5As shown, a button may be provided on both the left and right walls of the box cover 2, which are the main driver button 100 and the co-driver button 200, respectively, and a first opening and closing mechanism is provided on the main driver side and a second opening and closing mechanism is provided on the co-driver side inside the box body 1. When the user needs to open the heating and cooling box from the main driver side, the main driver button 100 may be pressed, at which time the first opening and closing mechanism on the main driver button 100 side is contacted and locked, and the box cover 2 can rotate around the axis of the second opening and closing mechanism to open the accommodating cavity 11; when the user needs to open the heating and cooling box from the co-driver side, the co-driver button 200 may be pressed, at which time the second opening and closing mechanism on the co-driver button 200 side is contacted and locked, and the box cover 2 can rotate around the axis of the first opening and closing mechanism to open the accommodating cavity 11.

[0076] The present application also provides a vehicle, which includes the above-mentioned cold and warm box.

[0077] In the vehicle provided in the embodiment of the present application, a seal 3 is provided on the box cover 2 of the heating and cooling box, and the seal 3 can fill the gap between the box cover 2 and the box body 1 when the box cover 2 is closed to achieve sealing; at the same time, since the gas containing space 30 inside the seal 3 is in air pressure balance with the outside world (the space in the vehicle cockpit), when the heating and cooling box is cooling, the gas in the gas containing space 30 of the seal 3 is affected by the cold air, and the air pressure is lower than that of the outside world. At this time, under the influence of atmospheric pressure, part of the outside gas will be pressed into the gas containing space 30, and finally the gas containing space 30 maintains air pressure balance with the outside world. After the outside gas enters the gas containing space 30, the elastic seal 3 will expand and deform, while the size of the gap between the box cover 2 and the box body 1 remains unchanged. The larger the seal 3 expands, the tighter it fits with the surface forming the gap, and the better the sealing is. Compared with the heating and cooling box sealed by a sealing ring in the related art, it obviously has better sealing performance.

[0078] In addition, since the above-mentioned heating and cooling box is provided, it can meet the sealing needs of users in different usage scenarios of the heating and cooling box, has better adaptability, and can provide users with a better usage experience.

[0079] In some embodiments, the heating and cooling box can be embedded in the armrest box (the part between the main driver and the co-driver), and the armrest can be installed on the outside of the box cover 2 and rotatably connected to the box body 1 through a connecting piece to achieve the integration of the armrest and the box cover 2.

[0080] Optionally, the connecting member may be a pin.

[0081] In other embodiments, the heating and cooling box can be arranged behind the rear seat backrest of the vehicle, and the box cover is integrated with the part between the two rear seats. By opening and closing this part, the accommodating cavity in the heating and cooling box can be opened and closed.

[0082] It should be noted that the heating and cooling box can also be set in other places inside the vehicle, such as in front of the co-pilot seat, and technicians in this field can choose and adjust it according to actual needs.

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