[0042] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0043] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] Please refer to Figure 1-2 The present invention provides a stable and sealed vehicle-mounted temperature storage box, comprising:

[0045] A box body 1, wherein the box body 1 has a storage space; the box body 1 has an opening 2, and the opening 2 is connected to the storage space;

[0046] a sealing cover 4, the sealing cover 4 being arranged at the opening 2;

[0047] A multi-stage sealing body 6 is fixedly mounted on a side of the sealing cover 4 close to the opening 2; the multi-stage sealing body 6 comprises a plurality of sealing layers 5; the sealing layers 5 are used to abut against the box body 1 to keep the storage space sealed from the outside.

[0048] In some embodiments, the housing 1 includes a heat insulating layer for preventing the storage space from exchanging heat with the outside through the housing 1 .

[0049] Further, refer to Figure 8 , also includes:

[0050] A storage basket 3, which can be slidably installed in the storage space of the box body 1 and is fixedly connected to the sealing cover 4;

[0051] The storage basket 3 has a first state and a second state;

[0052] When the storage basket 3 is in the first state, the storage basket 3 is completely in the storage space, and the multi-stage sealing body 6 abuts against the opening 2, so that the storage space remains sealed from the outside;

[0053] When the storage basket 3 is in the second state, the storage basket 3 partially or completely extends out of the storage space, and the sealing cover 4 is separated from the opening 2 .

[0054] In some embodiments, a storage basket 3 is slidably provided on the inner shell of the box body 1 to facilitate the placement or removal of items.

[0055] Further, refer to Figure 7, the storage basket 3 is provided with a fixing ring 10; the box body 1 is provided with a fixing head 11;

[0056] When the storage basket 3 is in the first state, the fixing ring 10 and the fixing head 11 are engaged with each other to fix the relative positions of the storage basket 3 and the box body 1 .

[0057] Specifically, the storage basket 3 slides along the box body 1 , and when switching from the second state to the first state, the fixing ring 10 moves with the storage basket 3 , and finally engages with the fixing head 11 installed in the box body 1 to complete the fixation.

[0058] When the storage basket 3 is to be switched from the first state to the second state, the storage basket 3 is pulled forcefully, or the storage basket 3 is moved by the motor (the passenger activates or deactivates the motor via a control switch), so that the fixing ring 10 is disengaged from the fixing head 11. The motor is mounted inside the housing 1, and a gear is mounted on the driving end. The gear engages with a rack fixedly connected to the storage basket 3 to achieve transmission.

[0059] In some embodiments, the fixing head 11 is electrically controlled to switch states to achieve connection and disconnection with the fixing ring 10. The passenger can also control the state of the fixing head 11 by controlling a switch.

[0060] By means of the mutual engagement of the fixing ring 10 and the fixing head 11, when the storage basket 3 is in the first state, the relative position between the storage basket 3 and the box body 1 can be further fixed; when the vehicle shakes, the multi-stage sealing body 6 is less likely to be poorly sealed and to produce gaps.

[0061] In some embodiments, the fixing ring 10 and the fixing head 11 are locking structures; when they are plugged together, they fix the relative position of the sealing cover 4 and the box body 1. At this time, simply pulling the sealing cover 4 cannot separate from the box body 1. Only by using external force to separate the fixing ring 10 and the fixing head 11 can the sealing cover 4 be slid relative to the box body 1.

[0062] Further, refer to Figure 3-6 , the multi-stage sealing body 6 also includes:

[0063] The connecting portion 7 has one side fixedly connected to the sealing cover 4 and the other side fixedly connected to the plurality of sealing layers 5 , and is used to fix the relative positions of the sealing cover 4 and the plurality of sealing layers 5 .

[0064] Furthermore, the sealing layer 5 has two portions, which are connected to each other;

[0065] An obtuse angle is formed between the two sealing layers 5 , and the edges thereof that are away from each other face toward the opening 2 , so as to abut against the opening 2 .

[0066] Furthermore, when the two sealing layers 5 abut against the opening 2 at the same time and the storage space remains sealed, a vacuum area is formed between the two sealing layers 5 and the opening 2 .

[0067] Specifically, when opening 2 of box body 1 abuts sealing cover 4, a vacuum zone forms between them. Atmospheric pressure acts on the outside of the sealing cover, while the area where they abut is a vacuum, devoid of gas pressure. This creates a pressure differential across the abutment area, effectively sealing the opening 2 and sealing cover 4. This pressure prevents the seal from leaking and creating gaps during vibration, ensuring the vehicle-mounted temperature storage box maintains excellent low-temperature performance.

[0068] refer to Figure 5-6 The process of the two sealing layers 5 simultaneously contacting the opening 2 to form a vacuum area includes:

[0069] The two sealing layers 5 are in contact with the opening 2 of the box body 1, but no interaction force is generated between them; a closed triangular area is formed between the cross section of the two sealing layers 5 and the opening 2, and there is air inside the area;

[0070] The sealing cover 4 is pushed further, so that an interaction force is generated between the two sealing layers 5 and the opening 2, causing deformation. At the same time, the gas in the triangular area is also squeezed by the force, causing the two sealing layers 5 to deform. The squeezing of the internal gas creates a small gap between the two sealing layers 5 and the opening 2. The gas in the triangular area is discharged from the gap.

[0071] After all the gas in the triangular area is exhausted, the triangular area disappears, and the two sealing layers 5 are in close contact with the opening 2;

[0072] When the thrust on the sealing cover 4 is released, the two sealing layers 5 are about to return to their natural state. At this time, a triangular area that is airtight to the outside world is formed again between the two sealing layers 5 and the opening 2. The triangular area is a vacuum area. Since there is an air pressure difference on both sides of the sealing layer 5, the deformation of the two sealing layers 5 will only be partially restored. The restored elastic force and the air pressure difference are balanced with each other.

[0073] When the sealing cover 4 needs to be opened, the sealing cover 4 is pulled outward with force so that the two sealing layers 5 can overcome the pressure difference, and finally the box body 1 and the sealing cover 4 are separated from each other, and the vehicle-mounted temperature storage box can be opened.

[0074] Furthermore, the connecting portion 7 has a connecting groove 8; the sealing cover 4 has a connecting protrusion 9;

[0075] The connecting protrusion 9 is locked in the connecting groove 8 to fix the connecting portion 7 and the sealing cover 4 .

[0076] Specifically, the connecting portion 7 is engaged with the connecting protrusion 9 on the sealing cover 4 through the connecting groove 8 to fix the relative position between the two so that the two are not easily separated from each other, thereby causing the multi-layer sealing body 6 to lose its sealing effect.

[0077] Furthermore, the multi-stage sealing body 6 is a stacked ring structure and is arranged opposite to the opening 2 .

[0078] Specifically, the stacked ring structure enables the multi-stage sealing body 6 to completely abut against the opening 2, thereby achieving a multi-stage sealing effect.

[0079] In some embodiments, the stacked ring structure is a method in which the two sealing layers 5 are not connected to each other, but are respectively fixed to the connecting portion 7. This method can form a larger vacuum area and improve the adsorption effect of the negative pressure.

[0080] Furthermore, the multi-stage sealing body 6 is made of silicone rubber, PVC, EPDM rubber, chloroprene rubber or TPE.

[0081] Specifically, silicone rubber has good elasticity and temperature resistance and is the most common sealing strip material.

[0082] PVC (polyvinyl chloride) has the characteristics of low cost and is widely used.

[0083] Ethylene propylene diene monomer (EPDM) has good weather resistance and chemical resistance and can be used for sealing strips.

[0084] Neoprene has good physical and mechanical properties, and is resistant to heat, oil, acid, alkali, and sunlight, and can also be used for sealing strips.

[0085] TPE (thermoplastic elastomer) has good flexibility and temperature resistance and is also a commonly used sealing strip material.

[0086] Furthermore, it also includes:

[0087] The temperature regulating component 12 is connected to the box body 1 and is used to regulate the temperature of the storage space.

[0088] In some embodiments, the temperature control component 12 is a refrigerator that absorbs gas in the storage space and transfers heat to the outside to achieve a cooling effect.

[0089] In some embodiments, the temperature regulating component 12 is a heater for heating the storage space.

[0090] refer to Figure 9-10 The box body 1 also has an interlayer, which has a second storage space and also has an opening 2. The sealing cover 4 is abutted against the opening 2 to achieve sealing.

Those skilled in the art should understand that the scope of the invention is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept.
