Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 7, the armrest box with a heat preservation function includes a box body 1 disposed between two auxiliary instrument side plates 2, wherein the front ends of the auxiliary instrument side plates 2 extend forward to be fixedly connected with a main instrument desk, and the bottom ends of the auxiliary instrument side plates extend downward to be fixedly connected with a vehicle body floor.

The outer side wall edge of the box body 1 is provided with a first bulge 11 extending outwards, and the first bulge 11, the outer side wall of the box body 1 and the inner side wall of the auxiliary instrument side plate 2 form a cavity 12. Referring to fig. 6 and 7, an upper partition plate 13 and a lower partition plate 13 are arranged in the cavity 12 to divide the cavity 12 into three chambers from top to bottom, the chamber in the middle is used as the ventilation duct 6, that is, the chamber between the two partition plates 13 is used as the ventilation duct 6, and the upper chamber and the lower chamber are used as heat-insulating closed chambers, so that heat loss caused by air flow in the ventilation duct 6 is reduced, and the heat-insulating performance of the box body 1 is improved.

Referring to fig. 4 and 5, a second grid-shaped protrusion 21 is arranged in a region of the inner side wall of the auxiliary instrument side plate 2 corresponding to the box body 1, and a first heat insulation cotton 4 is arranged between the second protrusion 21 and the outer side wall of the box body 1. The box body 1 and the auxiliary instrument side plate 2 are fixedly connected in a clamping mode, a plurality of clamps 17 are arranged on the outer side wall of the box body 1, and clamping seats 23 matched with the clamps 17 in a one-to-one mode are arranged on the inner side wall of the auxiliary instrument side plate 2.

After box 1 and the fixed back of 2 joints of vice instrument curb plate, first arch 11 and baffle 13 further compress tightly first thermal-insulated cotton 4 on being latticed second arch 21, and second arch 21, the cotton 4 inside wall of vice instrument curb plate 2 and first thermal-insulated surround and form a plurality of heat preservation closed chamber that are latticed distribution, have further kept off the heat outward conduction in box 1, have promoted the heat preservation performance of box 1.

2 inside walls of vice instrument curb plate are equipped with six reference columns 22, be equipped with on the first thermal-insulated cotton 4 and correspond complex locating hole 41 with reference column 22, guaranteed that first thermal-insulated cotton 4 can cover 1 lateral wall of box comprehensively, improved box 1's heat preservation effect.

The outer surface of the first bulge 11 is fixed with second heat insulation cotton 5 to further improve the heat preservation effect of the cavity 12 and further improve the heat preservation capacity of the box body 1.

Specifically, through holes are formed in the front side and the rear side of the cavity serving as the ventilation duct 6, the front side through hole 14 is communicated with the front section of the rear air outlet pipe, the rear side through hole 15 is communicated with the rear exhaust air port, the rear air outlet pipe and the rear exhaust air port are of common structures of existing vehicle types, the front end of the rear air outlet pipe is connected with an air outlet of a vehicle air conditioning system, the rear end of the rear air outlet pipe is connected with the rear exhaust air port, and rear evacuation air conditioning and supply are achieved. An air inlet 16 communicated with the ventilation duct 6 is arranged on the side wall of the box body 1, and an air door 3 capable of being opened and closed is arranged in the air inlet 16. The setting of air duct 6 can be sent into box 1 inside with air conditioning system's hot-blast or cold wind by air intake 16 on the one hand, realizes the heating or the refrigeration of the inside object of box 1, has reached box 1 accuse temperature purpose, and on the other hand air duct 6 can regard as the amount of wind compensation structure in back discharge outlet, has improved the air-out effect in air conditioning system back discharge outlet.

Referring to fig. 8, the upper and lower edges of the air inlet 16 are provided with guide slots, and the air door 3 can slide along the guide slots in the front and back directions, and it should be noted that the air door 3 can also be other common opening and closing structures, such as a hinge or a snap, and details thereof are not repeated herein.
