The design of the spring 9 has the effect of buffering and weakening the collision force through the spring 9 after the mobile chassis body 3 collides, and also avoids the situation that the chassis body 3 directly collides with an object. The interior of the long column 8 is slidably connected with a slide rod 10, and a U-shaped frame 11 is fixedly installed on the surface of the slide rod 10. A soft pad B12 is fixedly installed on the surface of the U-shaped frame 11. The materials of the soft pads A6 and B12 are both natural rubber. The design of the natural rubber material of the soft pads A6 and B12 has the effect of buffering and protecting the chassis body 3 when the chassis body 3 collides.
[0025] Embodiment 2
[0026] See also Figure 1-4 The surface of the bottom plate 1 is provided with a slide groove 13, and the surface of the bottom plate 1 is penetrated with a fixing hole 14. A slider 15 is fixedly installed on the bottom surface of the chassis body 3, and the slider 15 is slidably connected with the slide groove 13. The design of the slide groove 13 and the slider 15 makes it easy to place the chassis body 3 on the bottom plate 1 and also makes it easy to remove it from the bottom plate 1, so as to facilitate the maintenance personnel to maintain and repair the test device inside the chassis body 3. The slider 15 is connected with rollers 16 for rolling inside. The number of rollers 16 is seven groups, and the seven groups of rollers 16 are evenly distributed at the bottom of the slider 15. The uniform design of multiple groups of rollers 16 makes it easy to control and adjust the sliding of the slider 15 and the chassis body 3 in the slide groove 13. A plug 17 is inserted in the fixing hole 14, and the plug 17 is connected to the slider 15 by a thread. The threaded connection design of the plug 17 and the slider 15 fixes the slider 15 and the chassis body 3 on the bottom plate 1.
[0027] Working principle: when moving the chassis body 3, it is only necessary to push the bottom plate 1 through the push handle 4 and the universal self-locking wheel 2, and the bottom plate 1 will drive the chassis body 3 to move. When the moving chassis body 3 collides with other objects, the other objects will first contact the soft pads B12 and soft pads A6, and the soft pads B12 will drive the U-shaped frame 11 to move toward the bottom plate 1 after being affected by the impact force, and the U-shaped frame 11 will drive the slide bar 10 to slide inside the long column 8. At the same time, the U-shaped frame 11 will also be affected by the elastic force of the spring 9 and move toward other objects, thereby protecting the chassis body 3 and the internal test device, thereby avoiding damage to the chassis body 3 or the electronic components inside the test device due to collision. When the situation occurs and the test device inside the chassis body 3 needs to be maintained and repaired, it is only necessary to rotate the insert 17, and after the insert 17 is rotated out of the slider 15, the insert 17 is pulled out from the fixing hole 14, and after the insert 17 is pulled out, the chassis body 3 is pushed again, and the chassis body 3 will drive the slider 15 to slide in the slide groove 13, and the slider 15 will drive the rotating shaft to roll inside the slider 15 when sliding, until the chassis body 3 is removed from the bottom plate 1. The design of the slider 15 and the slide groove 13 makes it easy to place the chassis body 3 on the bottom plate 1 and also makes it easy to remove the chassis body 3 from the bottom plate 1, thereby making it convenient for maintenance personnel to maintain and repair the test device inside the chassis body 3.
