[0015] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figures 1-2 The diagram shows a falling object buffer canopy for a driver's cab, comprising a canopy body 1 integrally welded to the top of the driver's cab. The upper surface of the canopy body 1 has an integrally formed cavity 2 with a top opening. A buffer assembly 3 is installed at the opening of the cavity 2. Several shock-absorbing components are installed on the lower surface of the buffer assembly 3 located within the cavity 2. Each shock-absorbing component includes a U-shaped seat 4 integrally formed at the bottom of the buffer assembly 3. A limiting pin 5 is inserted into the middle section of the U-shaped seat 4, and a limiting shoulder 6 is integrally formed at the lower end of the limiting pin 5. A vertical compression spring 7 is sleeved on the limiting pin 5 located between the limiting shoulder 6 and the middle section of the U-shaped seat 4. Inclined connecting rods 8 are hinged to both ends of the limiting shoulder 6. A fixed seat 9 is provided on the bottom of the cavity 2 below the U-shaped seat 4. A horizontal shaft 10 is provided between the two fixed seats 9. Slider blocks 11 are slidably connected to the horizontal shaft 10. The free end of each connecting rod 8 is hinged to the corresponding slider 11. A transverse compression spring 12 is sleeved on the horizontal shaft 10 between each slider 11 and the corresponding fixed seat 9. The buffer assembly 3 includes a buffer block 301 protruding from the opening of the cavity 2. A buffer base plate 302 is fixedly inserted into the lower end of the buffer block 301. The U-shaped seat 4 is integrally mounted on the lower surface of the buffer base plate 302. A T-slot 303 is formed on the lower surface of the buffer block 301, and a T-shaped protrusion 304 is formed on the upper surface of the buffer base plate 302. The T-shaped protrusion 304 is inserted into the T-slot 303, connecting the buffer block 301 and the buffer base plate 302. The outer peripheral surface of the cavity 2 is inclined downwards. The inclined outer peripheral surface of the cavity 2 facilitates that objects falling from the roof can fall along the inclined surface under the inertia of the vehicle during movement, avoiding continuous pressure on the roof. A front baffle 13 is provided at the front end of the cavity 2, protruding from the horizontal plane of the upper surface of the buffer assembly 3. The front baffle 13 prevents objects from falling from the front side of the roof, avoiding damage to the windshield on the front side of the cab.

[0017] When the falling object falls on the upper part of the ceiling body 1, the impact force, i.e. pressure, is formed on the buffer block 301, the buffer block 301 moves vertically downward under the action of the pressure, the buffer plate moves integrally with the buffer block 301, so that the U-shaped seat 4 extrudes the vertical compression spring 7 downward, the vertical compression spring 7 is first stressed (here, the horizontal compression spring 12 exists stress but is small, and most of the pressure is applied to the vertical compression spring 7), and when the vertical compression spring 7 is deformed to the maximum extent, the horizontal compression spring 12 is extruded through the cooperation of the connecting rod 8 and the sliding block 11, the horizontal compression spring 12 is deformed, the impact force is decomposed from the vertical direction and the horizontal direction, the pressure borne by the horizontal compression spring 12 and the vertical compression spring 7 is reduced respectively, the service life is improved, and the double protection effect is achieved, so that the buffer effect can be achieved when one compression spring fails.

[0018] The utility model is not limited to the above-mentioned embodiment, on the basis of the technical scheme disclosed in the utility model, the skilled in the art can make some replacement and deformation to some technical features according to the disclosed technical content without creative labor, and these replacement and deformation are all within the protection scope of the utility model.
