Driving resistance detection equipment and method based on lifting of automobile baggage rack

Abstract

The invention discloses driving resistance detection equipment and method based on lifting of an automobile baggage holder, which relates to the field of automobile baggage holder driving resistance detection. The driving resistance detection equipment comprises a base, a lifting assembly is arranged at the top of the base, the automobile baggage holder is installed at the top of the lifting assembly, sliding grooves are formed in the two sides of the top of the base, sliding blocks are arranged in the two sliding grooves, and polished rods penetrate through the sliding blocks; the polished rod is fixedly connected with the inner wall of the sliding groove, the two sets of sliding blocks are connected with the two sides of the bottom of the lifting assembly respectively, a containing groove is formed in the top of the base, a detection assembly is arranged in the containing groove and connected with the lifting assembly, and a wind speed detector is arranged at the top of the base. The position height of the automobile baggage holder can be adjusted through the lifting assembly, resistance detection at different position heights of the automobile baggage holder can be conveniently achieved, the automobile baggage holder is blown through an external fan, automobile movement is simulated, and what can be avoided is that external factors affect the experiment result; the resistance borne by the automobile baggage holder is detected through the detection assembly.

Description

technical field [0001] The invention relates to the technical field of automobile luggage rack running resistance detection, in particular to a running resistance detection device and method based on the lifting and lowering of the automobile luggage rack. Background technique [0002] The car luggage rack has both aesthetic and practical functions. It can not only make the car look cooler, but also come in handy when you are traveling. It can carry things that cannot fit in the luggage compartment, such as bulky luggage, bicycles, folding beds, etc. As long as the owner secures the cargo in place, especially if a luggage net is added to the cargo, more things can be carried. [0003] At present, the car luggage rack is usually fixed and installed outside the car roof as a vehicle exterior decoration function, which increases the driving resistance of the car and increases the fuel consumption of the car; the driving resistance of the car is a necessary parameter for the ch...

AI Technical Summary

Problems solved by technology

[0003] At present, the car luggage rack is usually fixed and installed outside the car roof as a vehicle exterior decoration function, which increases the driving resistance of the car and increases the fuel consumption of the car; the driving resistance of the car is a necessary parameter for the chassis dynamometer test of vehicle economy It is an important aspect to analyze the difference in vehicle economy, but the measurement cost is high through the vehicle, and it is greatly affected by external factors, resulting in large errors in the measurement results
