DETAILED DESCRIPTION

[0022] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Embodiment 1

The cold and warm storage box 2 is installed under the car door 1, and the space in this area is relatively abundant, so that the storage box has a large volume, so that passengers in the front and rear rows can conveniently use the cold and warm storage box when riding in the car; and the problem that passengers in the rear row cannot conveniently use the cold and warm storage box is solved.

[0025] For example, the lower inner side of the automobile door 1 here has a recessed area 12, the recessed area 12 has a mounting platform 13, the mounting platform 13 is provided with a storage box mounting hole 14, and the cold and warm storage box 2 is installed in the storage box mounting hole 14. During actual installation, the upper end of the cold and warm storage box 2 should be exposed from the storage box mounting hole 14.

[0026] Among them, the storage liner 21 here is an aluminum liner, and there is a placement cavity 22 in the storage liner 21. The upper end of the storage liner 21 is open and the lower end is closed. The upper end of the cold and warm storage box 2 has a placement opening 23 that matches the opening of the upper end of the storage liner 21, and the placement opening 23 is connected to the placement cavity 22.

[0027] Preferably, one end of the placement cavity 22 is a cylindrical cup placement cavity 221, and the thermoelectric cooling sheet 31 is preferably arranged at the bottom of the cup placement cavity 221. The cup placement cavity 221 is connected to the long strip storage cavity 222, and the width of the storage cavity 222 gradually decreases from one end to the other end where the storage cavity 222 is connected to the cup placement cavity 221. The cup placement cavity 221 can be used to place cups or drinks, and the storage cavity 222 can be used to place objects or food.

[0028] Further, the thermoelectric semiconductor heating and cooling structure 3 here includes a thermoelectric cooling sheet 31 arranged at the lower end of the storage liner 21, one side of the thermoelectric cooling sheet 31 is in contact with the lower end surface of the storage liner 21, and the other side of the thermoelectric cooling sheet 31 is in contact with the substrate 321 of the heat dissipation fin 32, and one side of the heat dissipation fin 32 is provided with a heat dissipation fan 33 corresponding to the heat dissipation fin 32. A storage box switch 11 connected to the thermoelectric cooling sheet 31 and the heat dissipation fan 33 is provided on one side of the upper end of the heating and cooling storage box 2, and the heating and cooling state switching and temperature control are controlled by the storage box switch 11.

[0029] Furthermore, the upper end of the heat dissipation fin 32 is fixed to the lower end of the storage liner 21 by bolts 34, and the thermoelectric cooling sheet 31 is clamped and fixed between the base plate 321 of the heat dissipation fin 32 and the storage liner 21, and a sealing heat-insulating foam 35 is provided between the base plate 321 of the heat dissipation fin 32 and the storage liner 21, and the bolt 34 can pass through the sealing heat-insulating foam 35 to connect with the lower end of the storage liner 21, and the sealing heat-insulating foam 35 has a mounting hole 36, and the thermoelectric cooling sheet 31 is arranged in the mounting hole 36. Among them, the storage liner 21 is wrapped with a heat-insulating layer 24 matching the outer side of the storage liner 21 in the circumferential direction.

[0030] In this embodiment, in order to improve the sealing and heat preservation effects, the lower end of the cold and warm storage box 2 is open and closed by the air duct cover 25, and the heat dissipation fins 32 and the heat dissipation fan 33 are both arranged at the lower end of the air duct cover 25, and a positioning hole 26 is provided on the air duct cover 25, and the upper end of the positioning hole 26 has an annular step 27, and the sealing and heat-insulating foam 35 is arranged in the annular step 27, and the heat dissipation fins 32 are arranged at the lower end of the positioning hole 26.

[0031] The air duct 4 is formed between the air duct cover plate 25 and the inner side of the automobile door 1, the heat dissipation fins 32 and the heat dissipation fan 33 are both arranged in the air duct 4 and the heat dissipation fins 32 and the heat dissipation fan 33 are located between the air inlet 41 and the air outlet 42, and the air inlet 41 and the air outlet 42 are both located at the lower inner side of the automobile door 1.

[0032] The principle of this embodiment is that the cooling and heating functions of the cold and warm storage box 2 are realized by the operation of the thermoelectric semiconductor cold and warm structure 3. When the thermoelectric semiconductor cold and warm structure 3 is in cooling operation, the thermoelectric cooling sheet 31 is energized, and the contact surface between the thermoelectric cooling sheet 31 and the storage liner 21 generates cold energy, which is transferred to the storage liner 21, causing its temperature to decrease, thereby achieving the effect of cooling the storage box. At the same time, the contact surface between the thermoelectric cooling sheet 31 and the heat dissipation fin 32 generates heat, and the heat dissipation fan 33 accelerates the air flow around the heat dissipation fin 32 to take away the heat on the heat dissipation fin 32. The working principle is the same when the storage box is in heating operation. You only need to reverse the power supply direction of the thermoelectric cooling sheet 31 to reverse the cooling surface and heating surface of the thermoelectric cooling sheet 31.
