[0032] In the prior art, split refrigerated compartments generally adopt the form of a keel frame plus polyurethane insulation material plus a surface support plate, that is, the keel frame is first used as a fixed support for the entire vehicle compartment, and then the polyurethane insulation material is cut and added between the keels for heat insulation, and finally the inner wall of the compartment is fixed with a support plate (generally a stainless steel plate or a fiberglass plate) to form a whole. This type of split refrigerated compartment has the following disadvantages: 1) The loss of polyurethane cutting is relatively large, so the material cost is high, which increases the production cost of the compartment; 2) The weight of the compartment is heavy, resulting in a heavier overall weight, which is not conducive to the vehicle's endurance; 3) The volume of this type of split refrigerated truck is small, resulting in limited cargo transportation volume. 4) This type of split refrigerated compartment is widely used in traditional truck-type transportation, but VAN-type vehicles and new energy vehicles are more restricted, resulting in its low versatility.
[0033] The outer surface of an integrated refrigerated compartment is generally formed with fiberglass, which is then embedded in the mold and then foamed with polyurethane. This type of integrated refrigerated compartment has the following disadvantages: 1) The thickness of the compartment panel required for this type of compartment is 70-80mm to meet the requirements of refrigerated trucks, resulting in a smaller body volume and limited cargo transportation; 2) The surface fiberglass and polyurethane foaming require mold molding, which results in high box development costs, high mold maintenance costs, and a long development cycle; 3) Due to the box mold molding, it is inconvenient to adjust the box form and structural dimensions; 4) The density required for box panel foaming is generally above 50kg / m3, and fiberglass is 1.5-2g / cm3, resulting in a heavier box panel, which is not conducive to the vehicle's endurance; 5) This type of integrated refrigerated compartment is also not suitable for VAN-type vehicles and new energy vehicles, resulting in its low versatility.
[0034] In view of this, the present invention proposes a carriage 100 for a vehicle 200 , which may be a VAN vehicle, a new energy vehicle, a traditional oil-driven truck, or the like.
[0035] In the embodiment of the present utility model, Figure 1 and Figure 2 As shown, the carriage 100 includes a plurality of carriage panels 110, at least one of the carriage panels 110 includes a support plate 111 and an inner panel 112 arranged on the inner side of the support plate 111, the support plate 111 and the inner panel 112 are spaced apart, and a first aerogel layer is provided on the outer side of the support plate 111, and a second aerogel layer is provided on the inner side of the inner panel 112.
[0036] Specifically, the support plate 111 is provided as the main support of the carriage 100, and is arranged on the periphery, and the inner plate 112 is provided on the inner periphery and is spaced from the outer plate, thereby blocking the transmission of heat. The outer layer of the support plate 111 is provided with a first aerogel layer, which can be used as a heat insulation layer 113, has a low thermal conductivity, has very significant effects in both heat insulation and heat preservation, and has high tensile and compressive strength, and has the characteristics of fireproof, flame retardant, water repellent, sound insulation and light weight, which can effectively protect the carriage 100, and the first aerogel layer is thinner and can achieve a better heat preservation effect with a thinner thickness, thereby reducing the thickness of the carriage plate 110 and increasing the space of the carriage 100. Moreover, the first aerogel layer is convenient to be arranged outside the support plate 111 in a conformal manner, without relying on mold molding, and without corresponding cutting, so as to facilitate processing, thereby reducing processing costs and processing procedures, thereby controlling the cost of the whole vehicle. Moreover, the low density of aerogel helps to reduce the overall weight of the carriage 100 and improve the endurance of the whole vehicle. A second aerogel layer is provided on the inner side of the inner panel 112 to further block the loss of internal heat, further improve the heat insulation effect of the compartment 100 , and achieve a better refrigeration effect with a thinner compartment panel 110 .
[0037] In one embodiment, the first aerogel layer is formed by coating aerogel on the outer surface of the support plate 111. Preferably, the first aerogel layer is formed by spraying aerogel on the outer surface of the support plate 111. In the actual processing process, the aerogel thermal insulation slurry is first mixed with water in a certain ratio, and then sprayed on the outer side of the support plate 111 with a spray gun, a spray pot, a spraying device, etc. After spraying, it is baked at low temperature or dried by natural wind or natural sun drying. After drying, the above process is repeated for further spraying until the thickness required by the required thermal insulation level design is reached.
[0038] This coating method does not affect the preset mounting structure or mounting holes on the support plate 111, so that the shape of the support plate 111 does not need to be significantly adjusted, and the refrigerated truck body can be directly modified on the body structure, thereby simplifying the design of the compartment plate 110 and saving development costs and development cycles. Compared with directly brushing the outer surface of the support plate 111 to the required thickness, the thickness of the aerogel sprayed by this coating method is more uniform and more conducive to thickness control. Compared with forming an aerogel felt layer and then fixing it as a whole on the support plate 111, this solution simplifies the production process, can be installed on the support plate 111 in a shape-fitting manner, and helps to further thin the compartment plate 110. Of course, in other embodiments, the first aerogel layer can also be formed by brushing aerogel on the outer surface of the support plate 111; or the aerogel forms an aerogel felt layer and is attached to the outer surface of the support plate 111 as a whole.
[0039] Furthermore, a first protective layer is provided on the outer surface of the first aerogel layer to protect the first aerogel layer, such as during paint spraying. Dust removal, oil removal, electrophoresis and rust prevention can also be performed before spraying the first aerogel layer, thereby strengthening the close bonding between the aerogel insulation slurry and the body sheet metal and reducing the possibility of accidental shedding of the first aerogel layer.
[0040] In another embodiment, the second aerogel layer is formed by coating aerogel on the inner surface of the inner panel 112. Preferably, the second aerogel layer is formed by spraying aerogel on the inner surface of the inner panel 112. In the actual processing, the aerogel insulation slurry is first mixed with water in a certain ratio, and then sprayed on the inner surface of the inner panel 112 with a spray gun, a spray pot, a spraying device, etc. After spraying, it is baked at low temperature or dried by natural wind or natural sun drying. After drying, the above process is repeated for further spraying until the thickness required by the required insulation level design is reached.
[0041] This coating method does not affect the preset mounting structure or mounting holes on the inner panel 112, so that the shape of the inner panel 112 does not need to be significantly adjusted, and the refrigerated truck body can be directly modified on the body structure, thereby simplifying the design of the compartment panel 110 and saving development costs and development cycles. Compared with directly brushing the inner surface of the inner panel 112 to the required thickness, the thickness of the aerogel sprayed by this coating method is more uniform and more conducive to thickness control. Compared with forming an aerogel felt layer and then fixing it as a whole on the inner panel 112, this solution simplifies the production process, can be installed on the inner panel 112 in a form-fitting manner, and helps to further thin the compartment panel 110. Of course, in other embodiments, the second aerogel layer can also be formed by brushing aerogel on the inner surface of the inner panel 112; or the aerogel forms an aerogel felt layer and is attached to the inner surface of the inner panel 112 as a whole.
[0042] Furthermore, a second protective layer is provided on the inner surface of the second aerogel layer to protect the second aerogel layer, such as during paint spraying. Dust removal, oil removal, electrophoresis and rust prevention can also be performed before spraying the second aerogel layer, thereby strengthening the close combination of the aerogel insulation slurry and the body sheet metal and reducing the possibility of accidental shedding of the second aerogel layer.
[0043] In order to further improve the heat insulation effect of the carriage plate 110, in one embodiment, referring again to Figure 1 to Figure 2, a heat insulation layer 113 is provided between the support plate 111 and the inner plate 112. This further isolates the heat from being transferred between the support plate 111 and the inner plate 112, thereby improving the heat insulation effect of the compartment plate 110 and ensuring the refrigeration effect of the compartment 100. Moreover, this formation form of the compartment plate 110 can further reduce the thickness of the compartment plate 110. When the compartment 100 is required to reach the freezing level of the compartment 100, the thickness of the compartment plate 110 can be controlled at 30 cm. Compared with the prior art, the thickness of the compartment plate 110 is 70 cm-80 cm. This solution greatly reduces the thickness of the compartment plate 110, thereby increasing the refrigeration space. When the compartment 100 is required to reach the freezing level of the compartment 100, the thickness of the compartment plate 110 can be controlled at 25 cm.
[0044] In one embodiment, the heat insulating layer 113 is configured as a heat insulating cotton layer, which can be directly bonded to the inner side of the support plate 111 and / or the outer side of the inner plate 112, so as to ensure the fixation of the heat insulating cotton layer. In another embodiment, it can also be connected to the support plate 111 and / or the inner plate 112 only by fasteners. In other embodiments, the heat insulating cotton layer can be bonded to the inner side of the support plate 111 and / or the outer side of the inner plate 112 at the same time, and connected to the support plate 111 and / or the inner plate 112 by fasteners; or the heat insulating cotton layer is directly sandwiched between the support plate 111 and the inner plate 112.
[0045] In another embodiment, the heat insulating layer 113 is configured as a foam insulation layer. The foam insulation layer can be directly formed between the support plate 111 and the inner plate 112 through a foaming process. The material used for the foam insulation layer can be PU material, XPE material, EVA foam material, XPX foam material, etc.
[0046] In the actual processing process, the overall design of the compartment 100 can be carried out first, and then the refrigeration design can be carried out, or the original compartment 100 structure can be modified into a refrigerated compartment 100. Therefore, in one embodiment, the support plates 111 of the multiple compartment panels 110 are integrally formed, and the multiple inner panels 112 are spliced on the inner side of the support plates 111. Specifically, the multiple support plates 111 are an integrally formed compartment 100, and the inner side of the support plates 111 is reserved with space for the installation of the inner panels 112, and the support plates 111 do not need to be separated from the main body structure of the vehicle body. The multiple inner panels 112 are all arranged on the inner side of the support plates 111, and then spliced with each other, thereby simplifying the refrigeration design and realizing the refrigeration modification in the original compartment 100 structure.
[0047] In the actual processing process, the refrigeration design of multiple compartment panels 110 can also be carried out separately first, and then they are spliced together to form the compartment 100. In another embodiment, the multiple compartment panels 110 include a top panel 114, a bottom panel 115 and multiple side panels 116, and the top panel 114, the bottom panel 115 and the multiple side panels 116 all include a support plate 111 and an inner panel 112, and the top panel 114, the bottom panel 115 and the multiple side panels 116 are spliced with each other. Therefore, the forming of the compartment panel 110 used in this solution is more flexible, which makes the formation of the compartment 100 more flexible, and improves the versatility of the compartment panel 110.
[0048] And a mounting position can be reserved on the compartment plate 110, which can be a mounting hole for assembly with other structures of the vehicle body (such as a door), or other mounting structures. Furthermore, a water outlet is preset on the compartment plate 110. This facilitates the discharge of moisture in the compartment 100. Furthermore, ventilation holes are preset on the compartment plate 110 to ensure ventilation of the compartment 100. That is, the compartment plate 110 in this solution supports the pre-design of the structure of the compartment 100 itself, and the subsequent refrigeration design will not affect the original function of the compartment plate 110.
[0049] In some carriages 100, the doors of the carriage 100 are configured as sliding doors. Because in this solution, the thickness of the modified carriage panel 110 is relatively thin, which will not cause interference with the sliding of the sliding doors, so the function of the sliding doors can be retained without redesigning the doors, thereby simplifying the design process.
[0050] In one embodiment, again referring to Figure 1 and Figure 2 , the support strength of the support plate 111 is greater than or equal to the support strength of the inner plate 112. Specifically, since the support plate 111 is often used as a support for the car body 110, the required strength is relatively large, and the inner plate 112 is used to be spaced apart from the support plate 111 to block heat transfer, so the support strength of the support plate 111 is greater than or equal to the support strength of the inner plate 112, which can not only ensure the overall strength of the car body 110, but also reduce the strength redundancy of the car body 110 and reduce the overall weight of the car 100. To ensure that the support strength of the support plate 111 is greater than or equal to the support strength of the inner plate 112, the thickness of the support plate 111 can be increased so that the thickness of the support plate 111 is greater than or equal to the thickness of the inner plate 112, or a structure such as a reinforcing rib can be set on the support plate 111. Or the support plate 111 and the inner plate 112 are made of different materials, such as the support plate 111 can be configured as a reinforced plate such as a glass fiber reinforced plastic plate, a wooden plate, a metal plate, a plastic plate, etc., such as a stainless steel plate, an aluminum plate, a PVC plate, etc. The inner panel 112 may be configured as sheet metal.
[0051] The utility model also proposes a vehicle 200, which includes a car body 100. The specific structure of the car body 100 refers to the above-mentioned embodiment. Since the vehicle 200 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.
[0052] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
