Technical Field
[0001] The utility model relates to a low wind resistance box body device, in particular to a low wind resistance box body device. Background Art
[0002] The background technology of low wind resistance box device mainly involves the wind resistance problem encountered by trucks in the logistics industry. With the rapid development of the logistics industry, the air resistance encountered by trucks during transportation has a significant impact on energy consumption and noise. Due to the large size of the cargo box and the large area of the windward surface, the wind resistance is particularly serious. Therefore, reasonable measures need to be taken to reduce the high energy consumption and high noise problems caused by high wind resistance when the vehicle is running.
[0003] In order to reduce wind resistance, traditional vans usually have a deflector on the top of the cab, which uses a slope to transition the height difference between the cab and the cargo compartment, allowing the air flow to flow to a higher place, thereby reducing the air resistance on the cargo compartment. However, this device has low versatility and cannot be applied to long-head cab models. This type of deflector cannot completely achieve the purpose of separating the airflow, and when severe deformation occurs, it is easy to cause a large load impact on the cargo box sheet metal, increasing wind resistance and wind noise. Utility Model Content
[0004] The main purpose of the utility model is to provide a low wind resistance body device to solve the problems raised in the relevant technology. In order to reduce wind resistance, traditional van trucks usually set a deflector on the top of the cab, and transition the height difference between the cab and the cargo compartment through an inclined surface, so that the airflow flows to a higher place, thereby reducing the air resistance of the cargo compartment. However, this device has low versatility and cannot be applied to long-head cab models. This deflector cannot completely achieve the purpose of separating the airflow, and when severe deformation occurs, it is easy to cause a large load impact on the cargo box sheet metal, increasing wind resistance and wind noise.

[0006] The air deflector also includes arc surface three and arc surface four, which cooperate with arc surface one and arc surface two to allow wind to flow through the four sides of the air deflector, thereby preventing the airflow from staying in front of the vehicle.
[0007] Furthermore, a support block is fixedly connected to the top of the carriage, and an arc plate is fixedly connected to one side of the outer surface of the support block. The drooping front end of the arc plate is located on the same horizontal plane as the second arc surface and matches the inclination of the second arc surface.

The mounting strip is close to the carriage and a bolt is passed through the mounting strip and screwed into the carriage to fix the mounting strip.

[0011] Furthermore, a T-shaped hole is provided on the outer surface of the inclined panel, and the T-shaped hole fits the rear part of the carriage.
[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model installs the deflector at the front end of the vehicle compartment, and uses the inclined surface of the deflector to guide the airflow to the upper side and the two sides, thereby reducing the resistance received by the vehicle during movement.
