Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle passive safety test devices, and particularly relates to an electric mobile lifting device suitable for a car collision human body model. Background Art

[0002] As an important indicator for the safety assessment of automobiles by safety agencies in various countries around the world, automobile collision tests are an important reference for automobile factory designers to carry out automobile safety design. By conducting vehicle collision tests under different working conditions, collision information is collected using human models and various sensor equipment to analyze the damage of the human models. The collision test human model equipment is equipped with a large number of sensors and cables to collect and transmit test data. Engineers use this data to evaluate the condition of the human model and the performance of the vehicle during a collision. Therefore, human models play a vital role in automobile collision tests. Since automobile collision safety performance tests are non-repeatable and unique tests, in order to accurately record the movement and injuries of vehicles and occupants, higher requirements are placed on the human model equipment used for testing. During the test preparation process, the movement and installation of the human model from the storage device to the car must be strict and cautious. Some adult-sized collision human models weigh up to more than 100 kilograms, and it is quite difficult to carry and install them by manpower alone.

[0003] There are some auxiliary lifting devices in the prior art, but generally the adjustment performance is relatively poor, such as height adjustment and angle adjustment. For example, patent CN212609198U discloses a multifunctional crane for lifting a dummy for a collision test, which has the above disadvantages. Utility Model Content
