[0001] The utility model relates to the technical field of transport vehicles, in particular to a low-bed semi-trailer with a protective function. Background Art

[0002] The transport vehicle is also called a large flatbed truck, and its scientific name is a low-bed trailer. It is a special-purpose vehicle that is used to transport large and non-disassembled goods according to regulations. When transporting special equipment, a low-bed trailer is required to transport the special equipment so that the special equipment can be transported to the designated location for assembly.

[0003] Low bed trailers are needed for transporting special equipment. Among them, the "easy-to-use low bed semi-trailer" disclosed in the application number "CN212890051U" has solved the various disadvantages of the low bed semi-trailer that the large vehicle it carries may slide sideways or even fall off the low bed when encountering an emergency, thus making it difficult to ensure its safety.

[0004] However, there are still many defects in the actual use of transport vehicles with similar structures, such as: it does not have the function of providing safety protection for the driver, the cargo carried inside the vehicle is affected by the emergency braking of the vehicle, resulting in the cargo hitting the driving cabin and causing injuries to the driver, which reduces the safety effect of using the device and also reduces the reliability of using the device to transport cargo. At the same time, it does not have the function of auxiliary fixing of the cargo, and the cargo is easily moved due to bumps caused by the terrain, which reduces the stability of the cargo placement and the multifunctional effect of the device. Therefore, it is necessary to design a low-bed semi-trailer with a protective function. Utility Model Content

[0014] Beneficial Effects

[0015] The utility model provides a low-bed semi-trailer with a protective function. Compared with the prior art, it has the following beneficial effects:

[0016] 1. The pressure on the measuring plate is monitored in real time by energizing the pressure sensor. When the pressure sensor detects that the pressure value exceeds the preset value, the first solenoid valve tube is energized to transport the high-pressure gas stored in the gas tank to the inside of the airbag for rapid volume expansion. The airbag that is expanding can drive the resistance plate to extend out of the shell. The high pressure resistance of the airbag can facilitate the safety protection of the vehicle driver, avoiding the problem of the cargo carried inside the vehicle being affected by the emergency braking of the vehicle, resulting in the cargo hitting the driving cabin and causing injuries to the driver, realizing the function of safety protection for the driver, increasing the safety effect of the device, and ensuring the reliable effect of using the device for cargo transportation.

[0017] 2. The mounting plate can be pushed manually to drive the mounting seat to move horizontally. The mounting seat that moves horizontally can drive the support rod and the auxiliary plate to contact the outside of the cargo. The moving position of the mounting plate can be fixed by rotating the knob on the top of the mounting plate. The cargo placed inside the vehicle can be limited by the auxiliary plate. The damping rod and the shock-absorbing spring can be used together to absorb the vibration force of the cargo. The high elastic force of the shock-absorbing spring can be used to contact the cargo placed inside the vehicle through the auxiliary plate, thereby realizing the auxiliary fixing function of the cargo, avoiding the cargo from moving due to the influence of the terrain, increasing the multifunctional effect of the device, and ensuring the stable placement of the cargo.

[0026] The protection mechanism 2 comprises a shell 201, an airbag 202 is fixedly installed inside the shell 201, a pressure sensor 203 is fixedly installed outside the airbag 202, a measuring plate 204 is fixedly installed on one side of the pressure sensor 203, a contact plate 205 that contacts the measuring plate 204 is clamped and installed on one side of the shell 201, a gas tank 206 is fixedly installed on the top of the shell 201, a first solenoid valve tube 207 is fixedly installed on one side of the gas tank 206, and one side of the first solenoid valve tube 207 is connected with the airbag 202, and a second solenoid valve tube 208 is fixedly installed on one side of the first solenoid valve tube 207;

[0027] The auxiliary fixing mechanism 3 includes a mounting plate 301, a plurality of mounting seats 302 are equidistantly mounted on one side of the mounting plate 301, a tail plate 101 is fixedly mounted on one side of the onboard body 1, and a brake light 102 is fixedly mounted on one side of the tail plate 101;

[0028] A connecting frame 5 is fixedly installed on the other side of the board body 1, and a penetrating saddle 501 is fixedly installed on the top of the connecting frame 5. A driving box 4 is fixedly installed on one side of the bottom of the board body 1, and a moving wheel 401 is rotatably installed on the outer side of the driving box 4 through a bearing frame.

[0029] After the device is moved to a designated position, the saddle 501 can facilitate the subsequent docking operation between the traction vehicle head and the device. The tail plate 101 can provide an installation position for the brake light 102. The brake light 102 is powered on to generate light to prompt the rear vehicle to avoid and slow down. The drive box 4 can facilitate the installation of power output devices such as motors according to usage requirements. The moving wheels 401 can facilitate the movement of the traction device by external vehicles.

[0030] The pressure on the measuring plate 204 is monitored in real time by energizing the pressure sensor 203. When the pressure sensor 203 detects that the pressure value exceeds the preset value, the first solenoid valve tube 207 is energized to transport the high-pressure gas stored in the gas tank 206 to the airbag 202 for rapid volume expansion. The airbag 202 that is expanding can drive the resistance plate 205 to extend out of the shell 201. The high pressure resistance of the airbag 202 can facilitate the safety protection of the vehicle driver, avoid the cargo carried inside the vehicle from being affected by the vehicle's emergency braking, and avoid the problem of the driver being injured by the cargo hitting the driving cabin, thereby realizing the function of safety protection for the driver.

[0031] Figure 1 , Figure 3 , Figure 4 A second embodiment is shown, which mainly differs from the first embodiment in that a damping rod 303 is fixedly installed inside the mounting seat 302, and a shock-absorbing spring 304 is sleeved and installed on the outer side of the damping rod 303, a support rod 305 is fixedly installed at one end of the shock-absorbing spring 304, and an auxiliary plate 306 is fixedly installed at one end of the support rod 305; two groups of hydraulic rods 6 are fixedly installed at the bottom of the connecting frame 5, and a resistance foot 601 is fixedly installed at the output end of the hydraulic rod 6.

[0033] By manually pushing the mounting plate 301, the mounting seat 302 can be driven to move to a horizontal position. By moving the mounting seat 302 to a horizontal position, the support rod 305 and the auxiliary plate 306 can be driven to contact the outside of the cargo. Then, by rotating the knob on the top of the mounting plate 301, the moving position of the mounting plate 301 can be fixed. The cargo placed inside the vehicle can be limited by the auxiliary plate 306. Then, by using the damping rod 303 in conjunction with the shock absorbing spring 304, the vibration force exerted on the cargo can be absorbed. The high elastic force of the shock absorbing spring 304 can be used to contact the cargo placed inside the vehicle through the auxiliary plate 306, thereby realizing the auxiliary fixing function of the cargo. At the same time, by using the mounting plate 301 in conjunction with the rotation, the auxiliary fixing mechanism 3 can be disassembled according to usage requirements.
