The truck cab is different from the cab of a passenger car. When the truck needs to travel long distance, the driver can live in the cab for a long time, for example, the driver can boil water and cook food in the cab. Therefore, the cab of the truck needs to meet two special requirements, namely, the cab has a warm-keeping function and does not need passengers to feel cool; and secondly, the sealing function is required to be realized, and a large amount of condensed water is prevented from being generated on the inner surface of the top cover beam.

The cool air that feels in the driver's cabin in winter can let the passenger feel uncomfortable, can influence passenger's health even, and in humid weather, the panel beating internal surface can condense a large amount of water drops, can seriously influence the safety of driver's cabin travelling comfort and driving when a large amount of water drops drippage. The structure of truck driver's cabin includes the inside facing of roof planking and roof, and wherein, there is the clearance between the inside facing of roof planking and roof, and the clearance is more than 60mm usually, and consequently the water droplet on the panel beating can flow into in the clearance, and then can make the driver's cabin take place the problem that the frost was returned to the condensate easily, influences the living travelling comfort of driver's cabin and the safety of driving.

Based on this, the inventor of the present application has conducted intensive research and designed a cab and a vehicle to solve the problem of water condensation and frost return in the existing cab structure.

Fig. 1 is a cross-sectional view of a part of a structure of a cab according to an embodiment of the present application.

An embodiment of the present application provides a cab, as shown in fig. 1, including a cover assembly 100 and a sponge assembly 200, where the cover assembly 200 includes a first cover 110 and a second cover 120, the first cover 110 and the second cover 120 are oppositely disposed to form an accommodating space 130, the sponge assembly 200 includes a sponge 210 disposed in the accommodating space 130, and two opposite sides of the sponge 210 are respectively connected to the first cover 110 and the second cover 120.

This application is through setting up sponge 210 in accommodation space 130 between first apron 110 and second apron 120, so, utilizes sponge 210 to fill accommodation space 130, prevents that the air in accommodation space 130 from producing the convection current, avoids the continuation to condense water. Meanwhile, water drops in the accommodating space 130 are absorbed by the water absorption characteristic of the sponge 210, so that the problem that water condensation and frost return exist in the existing cab structure is solved, and the living comfort and the driving safety of the cab are effectively improved.

It will be appreciated that, in one aspect, the sponge 210 effectively fills the receiving space 130 between the first cover plate 110 and the second cover plate 120, blocking the contact of the water vapor with the outer cold sheet metal surface, while blocking the contact of the hot and humid air in the cab with the outer cold sheet metal, thereby avoiding the formation of condensation or frost. On the other hand, by using the water absorption property of the sponge 210, when the water drops fall into the accommodating space 130 between the first cover plate 110 and the second cover plate 120, the sponge 210 can absorb a large amount of water drops, thereby effectively avoiding the phenomenon that the water drops are in a string and flow down due to too much condensed water.

It should be noted that, when the driver's cabin air in vapor is more and there is certain difference in temperature indoor outer, vapor can form the condensate on the planking that has the room air to contact, and as time passes, the condensate can become cluster and drip downwards, can drench personnel and driver's cabin inside article when the water drips and falls, seriously influences the driving and riding experience. This application prevents to produce the water of congealing of persistence with the help of the air convection in the effectual separation accommodation space 130 of sponge 210, utilizes the water absorption characteristic absorption water droplet of sponge 210 simultaneously, and then avoids the water droplet whereabouts, prevents to influence and drives and take the impression.

Meanwhile, the sponge 210 has the obvious functions of cooling insulation, heat insulation, noise insulation and shock absorption, the cooling insulation and heat insulation characteristics of the sponge 210 can ensure that a warm living environment is provided for the passenger, the noise insulation and shock absorption characteristics of the sponge 210 can reduce the living interference of the external environment noise to the passenger, and the comfortable feeling of the cab is further improved.

In some embodiments, the sponge 210 comprises a PUR sponge, commonly referred to as a polyurethane open cell soft foam sponge, also referred to as a mesh sponge, a burst sponge, an open cell sponge, a filter sponge. It is worth mentioning that the PUR sponge is processed by common open-cell soft foam through the reticulation treatment, and the original facial mask or wall mask among foam networks is removed through the reticulation treatment, so that the main framework net structure is obtained. The void ratio of the PUR sponge is as high as 95%, the PUR sponge can be made into different shapes according to requirements, and the PUR sponge is convenient to form. The product made of the PUR sponge has excellent air permeability, good flexibility and higher mechanical strength.

In this way, by filling the accommodating space 130 with the sponge 210, the accommodating space 130 is divided into ten million independent small spaces by the sponge 210 by utilizing the characteristic of the PUR sponge having a large porosity. It can be understood that air is a poor heat conductor, and air flow between each air cell is extremely difficult, so that the temperature of air applied to the cold surface of the first cover plate 110 is the same as that of metal. The air attached to the second cover plate 120 is the same as the second cover plate 120, and thousands of small air grids in the middle form a perfect transition area to form a perfect air gradient, so that no obvious temperature difference is ensured, and the temperature difference is a key factor of water condensation, so that the accommodating space 130 is no longer likely to form water condensation and frost return.

In addition, the PUR sponge has better flame retardance, thereby improving the safety of passengers living in the cab. Meanwhile, the PUR sponge is flexible and elastic, is convenient to form, can be shaped into a complex shape to fill the accommodating space 130, is convenient to install, and has strong mechanical strength, so that the first cover plate 110 and the second cover plate 120 can be supported. The PUR sponge also belongs to a material with good durability and an environment-friendly material, is not easy to lose efficacy, decompose and deteriorate, and has durable and stable performance and higher reliability.
