Detailed Implementation

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] like Figure 1 As shown, this utility model provides a rapid and safe evacuation system for a medium-sized truck, comprising: a front positioning post 100; a front positioning chain 110, one end of which is detachably connected to the front positioning post 100 and the other end of which is detachably connected to the front of the truck; a rear positioning post 200; a rear positioning chain 120, one end of which is detachably connected to the rear positioning post 200 and the other end of which is detachably connected to the rear of the truck; a front wheel trolley 300, disposed at the bottom of the truck and behind the front wheels; a rear wheel trolley 400, disposed at the bottom of the truck and in front of the rear wheels; an evacuation track 500, located at the rear of the truck; and an evacuation trolley 600, which slides along the evacuation track 500, one end of which is connected to the rear wheel trolley 400 via a front evacuation chain 610 and the other end of which is connected to a winch 700 via a rear evacuation chain 620.

[0025] In the initial state, the two ends of the front positioning chain 110 are connected to the front positioning post 100 and the front of the truck, and the two ends of the rear positioning chain 110 are connected to the rear of the truck and the rear positioning post 200. The two positioning posts and the front and rear chains are used to position the truck in the test chamber for two-wheel drive hub testing.

[0026] When the vehicle under test experiences excessive heat or spontaneous combustion, the rear positioning chain 210 disconnects from the rear of the truck. The winch 700 winds the retraction chain 620, causing the retraction trolley 600 to slide along the retraction track 500. Simultaneously, the retraction trolley 600, via the front retraction chain 610, moves the rear wheel trolley 400 backward until the rear wheel trolley 400 lifts and secures the truck's rear wheels, pausing the retraction. Then, the front positioning chain 110 disconnects from the front of the truck, the winch 700 continues to wind the retraction chain 620, and the rear wheel trolley 400 continues to move backward. The truck, supported by the front wheel trolley 300 and the rear wheel trolley 400, and the backward movement of the rear wheel trolley 400, retracts backward until it is removed from the test chamber.

[0027] The aforementioned evacuation system is suitable for medium-sized trucks weighing ≤15t, with rear-wheel drive and front-wheel following configuration, to avoid the tested vehicle affecting the hub detection and equipment inside the test chamber.

[0028] Understandably, the structure of the rear wheel trolley 400 in this application is based on the structure of the existing vehicle mover, which uses a swing arm to limit the position of the wheel in the trolley and fix the wheel. The specific structure and principle are not described in detail here.

[0029] As an embodiment of this application, in order to more accurately monitor the temperature of the vehicle under test, an infrared thermal imager is installed between the front wheel trolley 300 and the rear wheel trolley 400. The infrared thermal imager is electrically connected to the controller. Once the battery of the vehicle under test experiences thermal runaway and rapid temperature rise during the test, the infrared thermal imager sends a signal to the controller, so that the controller can receive an alarm signal immediately. The controller immediately performs an emergency stop action on the two-wheel drive hub equipment, and the hub stops operating.

[0030] As an embodiment of this application, in order to more quickly disconnect the truck from the front and rear chains, the two ends of the front positioning chain 110 are detachably connected to the front positioning post 100 and the truck head via a release mechanism; the two ends of the rear positioning chain 120 are detachably connected to the rear positioning post 200 and the truck tail via a release mechanism. The release mechanism structure can refer to the release mechanisms in various automobiles and cranes in the prior art, and will not be described in detail here.

[0031] As an embodiment of this application, to facilitate the separation of the rear wheel trolley 400 from the evacuation trolley 600 and the removal of the rear wheel trolley 400, the front evacuation chain 610 is detachably connected to the rear wheel trolley 400 and / or the evacuation trolley 600 via a buckle. The evacuation trolley 600 and the rear wheel trolley 400 can be connected before vehicle testing, or they can be connected when evacuation is required.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
