The invention relates to a commercial vehicle tail anti-collision device, and discloses a commercial vehicle active control anti-collision mechanism for protecting passengers and vehicles on multiple angles. The mechanism has multiple anti-collision functions, and can actively control the mechanism parameter to reduce the collision harm to vehicles and passengers. The impact energy of the vehicle in rear-end collision is absorbed by mating reaction of a spring and a damper, the collisions at different positions are actively controlled, thereby reducing the damage of vehicles and passengers by the vehicle rear-end collision accident; meanwhile, a camera and a radar mounted on the mechanism can actively control the spring damper through an electric control mechanism, and lighten the harm caused by collision greatly through actively adjusting the parameters of the spring and the damper; moreover, multiple driving modes can be used for realizing the mated work of the radar and the camera, thereby protecting passengers, in particular to children, buildings, and vehicles, and realizing the safe driving.

The invention discloses an intelligent dustbin with good stability, which comprises a base, two symmetrical outriggers are fixedly connected to the outer surface of the base, and a cavity is opened at the bottom of each outrigger, and each cavity The first damping spring is fixedly connected to the inner top wall of each cavity, and two symmetrical snap-in grooves are opened on the inner wall of each cavity. The smart trash can with good stability can effectively buffer the actual pressure of the trash can body. The trash can body can move up and down and left and right, and can effectively slow down the external collision force, effectively avoiding The tipping and bumping of the smart trash can effectively avoid the fall of family members, and the safety performance is good, ensuring the effective contact between the rubber suction cup and the placement surface, and has a certain anti-skid performance, which effectively avoids the large size of the smart trash can. The amplitude movement effectively enhances the friction between the smart trash can and the placement surface, and has good stability.

A sea temporary floating table is mainly formed by a sea floating channel formed by light rectangle floating block units with strong stress frames, a floating platform connected with the channel and a storage drawing device. The invention is characterized in that the floating blocks are combined via leaf, hook and cable, to form the floating channel and platform quickly. The invention can be used in sea construction and rescue with low cost.

A buffer chamber (71) is connected to the outlet port (33) of an expansion mechanism (60). The buffer chamber (71) is formed in the shape of a cylinder extending in the direction of the flow of a cooling medium, and has a cross-sectional area greater than that of the outlet port (33). A rectifying plate (75) having a mesh section (75a) of a circular shape is provided inside the buffer chamber (71). The variation of pressure is relieved by the supply of pressure and the absorption of pressure by the buffer chamber (71), and also drops of the cooling medium are fined when they are passed through the plate (75).

The invention discloses an anti-collision cutting head of a laser cutting machine and belongs to the technical field of laser cutting machines. The anti-collision cutting head of the laser cutting machine comprises a fixing top plate; supporting frames are arranged on the left side and the right side of the bottom of the fixing top plate; an inner protective casing is movably arranged on the opposite end faces of the supporting frames through connection shafts; a front baffle is arranged at the bottoms of the two supporting frames; the rear end faces of the supporting frames are connected witha rear baffle; an electric telescopic rod is arranged on the top of an inner cavity of the inner protective casing; the bottom of the electric telescopic rod is connected with a cutting head througha fixing plate; fixing bases are arranged on the left side and the right side of the bottom of the inner protective casing; and the opposite end faces of the fixing bases are connected with a supporting plate. The front end of the supporting plate is provided with a limiting buffer device matched with the cutting head, so that the inner protective casing shakes front and back when bearing collision force so as to buffer the collision force, the cutting head in the inner protective casing can be bettered protected, the cutting head retracts back into the inner protective casing so as not to bedamaged, and the using performance of the laser cutting machine is improved.

The invention relates to an aluminum alloy lateral protection fence for a vehicle. The aluminum alloy lateral protection fence comprises a front bent beam, a hollow connecting beam and a back bent beam which are formed by extrusion of aluminum alloys, wherein the front bent beam comprises a front top plate and a front bottom plate, the surfaces of the front top plate and the front bottom plate are arranged in parallel in the horizontal direction, the lateral side at the front end of the front bottom plate is integrally connected with the lateral side at the back end of a front lower cambered bent plate, and the cambered surface of the front lower cambered bent plate bulges forwards and upwards; the back bent beam comprises a back top plate and a back bottom plate, the surfaces of the back top plate and the back bottom plate are arranged in parallel in the horizontal direction, the lateral side at the back end of the back bottom plate is integrally connected with the lateral side at the front end of a back lower cambered bent plate, and the cambered surface of the back lower cambered bent plate bulges backwards and upwards; and the front end of the connecting beam is inserted in a front insertion slot formed by the front top plate and the front bottom plate, and the back end of the connecting beam is inserted in a back insertion slot formed by the back top plate and the back bottom plate. When the protection fence collides with a human or a foreign matter, the aluminum alloy lateral protection fence for a vehicle can buffer the impact force, reduce the damage to the human and decrease the energy consumption in the running process of the vehicle.

The invention relates to a force-adsorption energy-storage anti-impact safety device, which comprises: a spring gas energy storage device, a spring return plug cylinder, a hydraulic oil tube, a one-way valve and a control valve, wherein the invention is characterized in that: the plug cylinder via the hydraulic oil tube and one-way valve is connected to the gas inlet of spring gas energy storage device whose gas outlet via the bypass hydraulic oil tube forms the circuit with the control valve and the spring return plug cylinder. With said invention, when the vehicle is impacted, it will cutoff power and brake, to adsorb and store external force, and convert the external force into the force resistant to the impact, to avoid rebounding the bumper and release the impact, to confirm the safety; and it will return after impact, to be used again. The invention can be mounted on the front and back bumpers, with simple structure.
