Description

Technical Field

[0001] This utility model relates to the technical field of vehicle compartment insulation equipment, specifically to a car body for a recreational vehicle. Background Technology

[0002] RVs combine the functions of both "house" and "vehicle," but their primary attribute is still that of a vehicle. They are a type of mobile vehicle equipped with essential home amenities. RVs mainly consist of two parts: the vehicle body and the cargo box.

[0003] A search revealed a patent with publication number CN210821998U that discloses a high-temperature resistant RV body. This patent includes a canopy with a serpentine cooling channel inside. The lower inner walls at both ends of the canopy are respectively equipped with a first water tank and a second water tank, and the outer walls of the water tanks are wrapped with cooling pipes. By setting up a reciprocating cooling channel and using cold water to achieve continuous cooling of the canopy, heat transfer from the canopy surface to the interior is prevented, keeping the interior of the canopy always cool and improving the overall comfort of the RV body. The patent primarily achieves this by adding cooling pipes to the frame layer and circulating cooled water within these pipes. The circulating water absorbs heat from the interior of the frame layer through the cooling pipes.

[0004] However, adding cooling pipes at the keel layer may reduce the space for insulation material placement, thereby lowering the insulation performance of the RV itself. Furthermore, during use, water droplets may form on the outer wall of the cooling pipes due to temperature differences. These droplets may seep into the insulation material and affect its performance. To address these issues, a new type of RV body is proposed. Utility Model Content

[0005] In view of this, the present invention provides a car body for a recreational vehicle. The present invention uses a cold air blower to deliver cold air to the air distribution chamber, so that cold air can circulate in each ventilation duct. The cold air can enter the cooling interlayer through the ventilation openings, thereby cooling the inner wall of the car body. This prevents water droplets generated on the outer wall of the cooling pipes from seeping into the heat insulation material during use, thus protecting the heat insulation material while cooling the car body, thereby improving the service life of the car body.

[0006] To solve the above-mentioned technical problems, this utility model provides a car body for a recreational vehicle, including a car body, a cooling interlayer inside the car body, multiple ventilation ducts inside the cooling interlayer, a cold air fan on the rear outer wall of the car body, the air outlet of the cold air fan passing through the car body and entering the cooling interlayer, and an air distribution chamber passing through the air outlet of the cold air fan passing through the car body, the air distribution chamber being vertically arranged, the air inlet of each ventilation duct being connected to the air distribution chamber, and multiple ventilation openings being provided through the upper and lower surfaces of each ventilation duct.

[0007] A positioning block is installed between every two ventilation openings on the same floor of the ventilation duct. The positioning block is used to connect the ventilation duct to the main body of the carriage, thereby supporting the ventilation duct.

[0008] The positioning block is rectangular with an opening in the middle. The opening is used to fit onto the ventilation duct and fits tightly against the outer wall of the ventilation duct. One side of the positioning block is connected to the main body of the carriage, and the other side of the positioning block is connected to the cooling interlayer.

[0009] A crash barrier is installed between the two axial positioning blocks. The crash barrier is used to prevent damage to the inner compartment from the initial impact force when the body of the carriage is hit by a collision. The crash barrier is wavy in shape.

[0010] The cooling interlayer contains an inner compartment for personnel use, which is used to install interior decorations and living utensils. The top of the inner compartment is equipped with a heat insulation layer to increase the heat transfer coefficient of the top of the carriage body. A gap is left between the heat insulation layer and the inner top wall of the carriage body.

[0011] The air cooler is equipped with a support frame at the bottom. The support frame is used to connect the air cooler to the body of the carriage, thereby supporting the air cooler. The support frame is connected to the outer wall of the carriage body.

[0012] The bottom of the inner compartment is equipped with an insulation layer, which is used to insulate the heat between the bottom of the carriage body and the inner compartment. This allows the air cooler to cool the inner compartment through the ventilation duct, thus improving the cooling effect. The upper surface of the insulation layer is equipped with a wooden board layer, which is used to slow down the rate at which heat from the bottom of the carriage enters the inner compartment.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. Cool air is delivered to the air distribution compartment by a cooler, allowing cool air to circulate through each ventilation duct. The cool air can enter the cooling interlayer through the vents, thereby cooling the inner wall of the carriage body. This prevents water droplets from the outer wall of the cooling pipes from seeping into the insulation material during use, thus protecting the insulation material while cooling the carriage body and improving the service life of the carriage.

[0015] 2. The anti-collision plate is used to reduce the damage to the inner compartment caused by the initial impact force when the body of the carriage is hit by a collision, thereby improving the anti-collision level of the body of the carriage and thus improving the anti-collision performance of the body of the carriage.

[0016] 3. The insulation layer is used to insulate the heat between the bottom of the carriage body and the inner compartment, thereby improving the cooling effect when the air cooler cools the inner compartment through the ventilation duct. The wooden board layer is used to slow down the rate at which heat from the bottom of the carriage enters the inner compartment, thus making the temperature inside the inner compartment relatively stable.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-8The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0027] like Figure 1-8 As shown: This embodiment provides a caravan body, including a caravan body 100. The caravan body 100 has an internal cooling interlayer 101 with multiple ventilation ducts 200. Each ventilation duct 200 is rectangular. The first section of each ventilation duct 200 is heat-fused or adhesively connected to an air distribution chamber 201. The end of each ventilation duct 200 is sealed. The end of each ventilation duct 200 can be connected and fixed to the other side of the air distribution chamber 201, or each ventilation duct 200 can have a vertical connecting plate at its end. This connecting plate connects the ends of multiple ventilation ducts 200 together, thereby improving the support capacity of the ventilation ducts 200. A cooler 300 is installed on the rear outer wall of the caravan body 100. The air outlet of the cooler 300 has a duct, which is sealed and connected to the air distribution chamber 201. The air outlet of the air cooler 300 passes through the body 100 of the carriage and enters the cooling jacket 101. The air outlet of the air cooler 300 passes through the body 100 of the carriage and is equipped with an air distribution chamber 201. The air distribution chamber 201 is rectangular. A sealing ring is provided between the bottom of the cooling jacket and the bottom of the carriage body 100. This sealing ring is rectangular and is used to prevent the cooling jacket from directly contacting the bottom of the carriage body 100. The bottom of the air distribution chamber 201 is sealed and connected to the bottom of the cooling jacket. The air distribution chamber 201 is set vertically. The air inlet of each ventilation duct 200 is connected to the air distribution chamber 201. Multiple ventilation openings 202 are provided through the upper and lower sides of each ventilation duct 200. The ventilation openings 202 are used to transport the cold air in the ventilation duct 200 to the cooling jacket, and then cool the inner compartment 400 through the cooling jacket. This compartment is independent of the air conditioner and does not conflict with the air conditioner in the cabin.

[0028] During use, the cold air generated by the air cooler 300 is delivered to the air distribution chamber 201. The air distribution chamber 201 is then connected to the multi-layer ventilation duct 200, allowing cold air to circulate through each ventilation duct 200 and enter the cooling interlayer 101 through the ventilation opening 202. This cools the inner wall of the carriage body 100, preventing water droplets from the outer wall of the cooling pipes from seeping into the insulation material during use. This protects the insulation material while cooling the carriage body 100, thus improving the service life of the carriage.

[0029] This embodiment provides a car body for a recreational vehicle.

[0030] like Figure 2 ,3 As shown in Figures 7 and 8: A positioning block 203 is provided between every two ventilation openings 202 on the same floor ventilation duct 200. The positioning block 203 can be made of stainless steel. The positioning block 203 is used to connect the ventilation duct 200 to the carriage body 100, thereby supporting the ventilation duct 200.

[0031] Its effect is that the positioning block 203 is used to connect the ventilation duct 200 with the carriage body 100, thereby supporting the ventilation duct 200.

[0032] like Figure 3 , 5 As shown in Figures 7 and 8: The positioning block 203 is rectangular and has an opening 204 in the middle. The opening 204 passes through the middle of the positioning block 203 and is used to fit onto the ventilation duct 200. The opening 204 is tightly fitted to the outer wall of the ventilation duct 200. One side of the positioning block 203 is connected to the carriage body 100, and the other side of the positioning block 203 is connected to the cooling interlayer 101.

[0033] Its effect is that the opening 204 is used to fit over the ventilation duct 200.

[0034] like Figure 2 , 3 As shown in Figure 4: A crash plate 205 is provided between each of the two axial positioning blocks 203. The crash plate 205 can be made of stainless steel. The crash plate 205 is used to prevent damage to the inner compartment 400 from the initial impact force when the body of the carriage 100 is hit by a collision. The crash plate 205 is wavy in shape, and both ends of the crash plate 205 are welded to the positioning blocks 203 on the same axis.

[0035] Its effect is as follows: the anti-collision plate 205 can be made of stainless steel, and the anti-collision plate 205 is used to prevent damage to the inner compartment 400 from the initial impact force when the body of the carriage 100 is hit by a collision.

[0036] like Figure 1 , 2 As shown in Figures 5, 7, and 8: The cooling interlayer 101 has an inner compartment 400 for personnel use. The inner compartment 400 is used to install interior decorations and living utensils. The top of the inner compartment 400 is provided with a heat insulation layer 401. The heat insulation layer 401 is fixed to the top of the inner compartment 400 by bolts. The heat insulation layer 401 is used to increase the heat transfer coefficient of the top of the carriage body 100. A gap is left between the heat insulation layer 401 and the inner top wall of the carriage body 100. This gap is used to connect the cooling interlayer 101 and the top of the inner compartment 400.

[0037] Its effects are as follows: the inner compartment 400 is used to install interior decorations and living utensils, and the heat insulation layer 401 is used to increase the heat coefficient of the top of the carriage body 100.

[0038] like Figure 1 , 4 As shown: The air cooler 300 has a support frame 301 at its bottom. The support frame 301 includes a support plate that supports the body of the air cooler 300. The support plate is fixed to the body of the air cooler 300 by bolts. Triangular brackets are provided on both sides of the bottom of the support plate.

[0039] Its effect is that the support frame 301 is used to connect the air cooler 300 to the carriage body 100, thereby supporting the air cooler 300.

[0040] like Figure 2 , 4 As shown in Figures 6 and 7: The bottom of the inner compartment 400 is provided with an insulation layer 402, which is embedded in the bottom of the inner compartment 400. The insulation layer 402 is used to insulate the heat between the bottom of the carriage body 100 and the inner compartment 400, thereby improving the cooling effect when the air cooler 300 cools the inner compartment 400 through the ventilation duct 200. A wooden board layer 403 is provided on the upper surface of the insulation layer 402. The wooden board layer 403 is fixed to the insulation layer 402 by bolts or adhesive. The wooden board layer 403 is used to slow down the speed at which heat from the bottom of the carriage enters the inner compartment 400.

[0041] Its effects are as follows: the insulation layer 402 is used to insulate the heat between the bottom of the carriage body 100 and the inner compartment 400, thereby improving the cooling effect when the air cooler 300 cools the inner compartment 400 through the ventilation duct 200; the wooden board layer 403 is used to slow down the rate at which heat from the bottom of the carriage enters the inner compartment 400, thereby making the temperature inside the inner compartment 400 relatively stable.

[0042] Working principle: The cold air generated by the air cooler 300 is delivered to the air distribution chamber 201. The air distribution chamber 201 is then connected to the multi-layer ventilation duct 200, so that cold air can circulate in each ventilation duct 200 and enter the cooling interlayer 101 through the ventilation port 202. This cools the inner wall of the carriage body 100, thereby preventing water droplets generated on the outer wall of the cooling pipes from seeping into the heat insulation material during use. This protects the heat insulation material while cooling the carriage body 100, thus improving the service life of the carriage.

[0043] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
