Problems solved by technology

[0003] When there is a rear-end collision of a small vehicle, due to the high height of its compartment from the ground, the front of the rear-end vehicle will plunge into the bottom of the truck compartment, causing major damage to the rear-end vehicle, and even casualties; this type of trailer The vehicle, whose compartment is a container, is unloaded and loaded by hoisting. Therefore, according to this situation, we have designed a vehicle that can be installed at the rear of the trailer frame to extend the distance and allow the front of the vehicle to absorb energy when it is inserted. , a vehicle bottom-mounted collision protection device that reduces collision damage

Embodiment 1

[0036]A vehicle bottom-mounted collision protection device, including a connection buffer structure 1 installed on the longitudinal beams on both sides of the vehicle, and a square steel frame 2 installed between the connection buffer structures 1 on both sides; compared with the traditional " A "shaped steel frame, the square steel frame 2 can deform and absorb energy, and the energy absorption capacity is stronger; the height of the square steel frame 2 is lower than the height of the longitudinal beam; this structure makes the square steel frame 2 move backward. , to avoid moving interference with the total amount in the future; the top of the square steel frame 2 is detachably provided with an energy-absorbing water tank 3, and the inside of the energy-absorbing water tank 3 is provided with a partition 4, and the partition 4 adopts double-layer Welding of steel plates; stronger pressure resistance; a first chamber 41 is formed at the rear of the partition 4, a second chamb...

Embodiment 2

[0039] The bottom of the energy-absorbing water tank 3 is provided with a water discharge pipe 311 communicating with the first chamber 41, and a ball valve is installed on the water discharge pipe 311; the energy-absorbing water tank 3 has a relatively large internal water storage capacity under normal conditions. , when the driver friend needs water, the drain pipe 311 can be temporarily opened to discharge the water, and after use, it can be replenished in time. The energy-absorbing water tank 3 can not only buffer and absorb energy with water, but also store water in an emergency.

Embodiment 3

[0041] The bottom of the energy-absorbing water tank 3 is provided with a pressure relief valve 312, the pressure relief valve 312 corresponds to the second chamber 42, and the pressure relief valve 312 is arranged at a position close to the partition plate 4; when When the piston plate 43 moves backward, the water holding space in the second chamber 42 is squeezed, and the water pressure increases at this time, and the pressure is released after breaking through the set value of the pressure relief valve 312; Hydraulic valve 312, under the effect of water pressure, may cause the energy-absorbing water tank 3 to crack and leak under the effect of water pressure; After the value is released, if the collision energy absorption has been completed in the pressure relief process, then the trouble of maintaining the energy-absorbing water tank 3 is saved.

Abstract

The invention discloses a vehicle bottom hanging type collision protection device. The device comprises connecting buffer structures installed on longitudinal beams on the two sides of a vehicle and asquare steel frame installed between the connecting buffer structures on the two sides. Compared with a traditional linear steel frame, the square steel frame can deform to absorb energy, and the energy absorption capacity is higher; the height of the square steel frame is lower than that of the longitudinal beam; by means of the structure, when the square steel frame moves backwards, movement interference between the square steel frame and the total square steel frame is avoided; an energy-absorbing water tank is detachably arranged above the square steel frame, and a partition plate is arranged in the energy-absorbing water tank and is formed by welding double layers of steel plates; higher anti-pressure capability is realized; the device can be installed at the tail of a frame of the trailer, the distance is prolonged, energy is absorbed when the head of the trailer is inserted, and collision damage to the trailer is reduced.

Description

technical field [0001] The invention relates to a vehicle bottom hanging type collision protection device. Background technique [0002] The chassis height of the trailer truck is relatively high, and due to the long length of the trailer part, there is a considerable distance between the rear of the compartment and the rear wheels. [0003] When there is a rear-end collision of a small vehicle, due to the high height of its compartment from the ground, the front of the rear-end vehicle will plunge into the bottom of the truck compartment, causing major damage to the rear-end vehicle, and even casualties; this type of trailer The vehicle, whose compartment is a container, is unloaded and loaded by hoisting. Therefore, according to this situation, we have designed a vehicle that can be installed at the rear of the trailer frame to extend the distance and allow the front of the vehicle to absorb energy when it is inserted. , A vehicle bottom-mounted collision protection devic...
