Description

Technical Field

[0001] The utility model relates to the technical field of new energy refrigerated trucks, in particular to a new energy commercial modified refrigerated truck. Background Art

[0002] With the development demand of cold chain transportation, there are a large number of refrigerated trucks modified from new energy vehicle models, especially series such as Chery Kai Rui Jiangtun E7 and Foton EV. In order to meet the heat preservation requirements, an inner door of the insulation compartment is often added inside the original rear door, and another inner door of the insulation compartment is also made at the original middle door with a heat preservation board with a thickness of more than 30 mm. The inner cavity volume of the insulation compartment made in this way will be reduced a lot, resulting in a reduction in the loading space of the cargo volume for each trip of the user, which brings about an increase in the single-trip transportation cost per piece of the user and an increase in the cost of transported items.

[0003] However, if no inner door is made inside the original rear door and the original middle door, although the volume space inside the insulation compartment can be increased, the system cooling capacity is required to be sufficient enough, and the design and layout of the refrigeration unit will be more sophisticated. Common refrigeration units include an inner machine assembly arranged inside the carriage and an outer machine assembly arranged outside the carriage. There are usually two installation methods for the outer machine assembly. The first one is to integrate the refrigeration outer machine assembly and set it on the roof of the refrigerated truck, such as Shanghai Datong bread refrigerated trucks and Jinbei bread refrigerated trucks, etc. The second one is to disassemble the refrigeration outer machine assembly into various components and install them scattered under the vehicle chassis.

[0004] However, the first method will cause an increase in the overall height of the vehicle, limited passing rate in and out of the freezer, and the outer machine is close to the cab, generating large noise and vibration. The second method causes the materials to be scattered and is not conducive to management. Moreover, due to the complex layout of pipelines and high and low voltage lines under the chassis of new energy vehicles, it brings difficulties to the installation and setting of the outer machine, thus reducing the convenience of installation and maintenance of the refrigeration outer machine of new energy commercial modified refrigerated trucks. Summary of the Utility Model

[0005] In order to improve the convenience of installation and maintenance of the refrigeration outer machine of new energy commercial modified refrigerated trucks, the utility model provides a new energy commercial modified refrigerated truck.

An electric control box assembly is arranged on the vehicle body. The electric control box assembly controls the operation of the internal unit assembly, the compressor and the condenser. The internal unit assembly, the compressor and the condenser are connected through a refrigerant pipeline.

[0008] By adopting the above technical solution, the electric control box assembly controls the operation of the internal unit assembly and the external unit assembly. The external unit assembly is installed under the chassis of the vehicle body, which will not increase the height of the whole vehicle. And the external unit assembly is divided into two parts for installation, reducing the probability that the overall installation of the external unit assembly occupies too much space and cannot be installed. At the same time, it improves the convenience of material management and storage, simplifies the routing layout of the refrigerant pipeline, thereby improving the convenience of installation and maintenance of the refrigeration external unit of the new energy commercial modified refrigerated truck.

[0009] Optionally, the first support frame is located on the side of the power battery of the vehicle body. A plurality of upwardly extending connecting brackets are arranged at intervals on the first support frame.

[0011] Optionally, a mudguard extending upward is arranged at one end of the first support frame close to the cab of the vehicle body. The top end of the mudguard is detachably connected to the chassis of the vehicle body. A side baffle extending upward is detachably connected to one side of the first support frame close to the outside of the vehicle body.

[0012] By adopting the above technical solution, the mudguard and the side baffle block the soil and sand carried by the wheels during the vehicle's travel, reducing the probability that the compressor and other accessories are damaged by external forces, so as to improve the protection of the compressor.

[0013] Optionally, the first support frame has a plurality of drain holes.

[0014] By adopting the above technical solution, multiple drain holes are used to drain the accumulated water in the first support frame, reducing the probability of the compressor and other accessories being damaged by immersion, thereby improving the protection of the outdoor unit assembly.

When the vehicle is running, the air inlet net plate can prevent the damage caused by flying stones, leaves or cloth paper generated during driving from flying in and the accumulation of dust, which may affect the heat dissipation of the condenser, thereby improving the working effect of the condenser.

[0019] Optionally, the indoor unit assembly includes an evaporator, and the refrigerant pipeline connects the evaporator, the compressor and the condenser in series to form a cooling circuit.

[0020] By adopting the above technical solution, the refrigerant pipeline connects the indoor unit assembly and the outdoor unit assembly.

[0022] By adopting the above technical solution, the refrigerant pipeline and the control wire harness are arranged in the cab, reducing the probability that the refrigerant pipeline and the control wire harness affect the loading space in the insulation box, thereby improving the loading space of the insulation box.

This not only reduces the probability of damage to the refrigerant pipeline and the control wire harness at the connection of the evaporator caused by the loaded goods, but also improves the cleanliness of the loading space in the insulation compartment.

[0025] Optionally, one side of the decorative panel close to the second routing hole has a side plate extending upward, and the top end of the side plate has an avoidance groove for avoiding the refrigerant pipeline.

[0026] By adopting the above technical solution, the refrigerant pipeline and the control wire harness connected to the evaporator pass through the routing hole and are then connected to the designated position.
