When the vehicle turns or only one side of the wheel passes over a bumpy road, the rear suspension of the semi-trailer will be subjected to a huge lateral offset force. Once the offset force exceeds the connection force between the rear suspension and the rear frame, it will have a great impact on the vehicle's driving stability and safety.

[0004] However, in the prior art, when the rear end of a semi-trailer is not fixed by the front end of the semi-trailer, the front end of the semi-trailer is unstable and prone to tipping due to the long front end of the rear end of the semi-trailer. Summary of the Invention

DETAILED DESCRIPTION

[0019] See also Figures 1 to 5 The utility model provides a rear support assembly of a semi-trailer, including a vehicle body 101 and a support mechanism, wherein the number of the support mechanism is two groups, and the two groups of support mechanisms are respectively arranged on both sides of the vehicle body 101, and each group of the support mechanism includes a hydraulic cylinder 102, a side mounting plate 103, a support assembly, an anti-skid pad 104 and an auxiliary assembly. The number of the side mounting plates 103 is two groups, and the two groups of side mounting plates 103 are respectively fixedly connected to the hydraulic cylinder 102 and are respectively located on both sides of the hydraulic cylinder 102, the support assembly is arranged at the lower end of the hydraulic cylinder 102, the number of the anti-skid pad 104 is two groups, and the two groups of anti-skid pads 104 are respectively arranged at the lower end of the support assembly, and the number of the auxiliary assembly is two groups, and the two groups of auxiliary assemblies are respectively fixedly connected to the hydraulic cylinder 102 and are respectively located on both sides of the hydraulic cylinder 102, and the two groups of hydraulic cylinders 102 are respectively adapted to the support assembly.

[0020] In this embodiment, two groups of support mechanisms are used to support one end of the vehicle body 101. Among the support mechanisms, the hydraulic cylinder 102 is installed on one side of the vehicle body 101. The extension of the hydraulic cylinder 102 causes the support assembly and the anti-slip pad 104 to contact the ground, thereby supporting the end of the vehicle body 101. When the hydraulic cylinder 102 is installed on one side of the vehicle body 101, it is fixed by the side mounting plate 103 and the bolts. During support, the hydraulic cylinder 102 is extended to cause the anti-slip pad 104 to contact the ground, thereby effectively preventing the end of the support assembly from slipping. At the same time, after the support assembly is fully unfolded, the auxiliary assembly supports the support assembly, thereby playing an effective auxiliary role in the support process. When support is not needed, the hydraulic cylinder 102 contracts so that the support assembly is no longer squeezed, so that the end of the support assembly is folded inward and tilted, thereby reducing space occupancy.

[0021] Furthermore, the support assembly includes a rotating shaft, a first support plate 105 and a second support plate 106. The rotating shaft is fixedly connected to the output end of the hydraulic cylinder 102 and is respectively located at the lower end of the hydraulic cylinder 102. The first support plate 105 is rotatably connected to the rotating shaft and is sleeved on the outer wall of the rotating shaft. The second support plate 106 is rotatably connected to the rotating shaft and is sleeved on the outer wall of the rotating shaft, and the first support plate 105 and the second support plate 106 are adapted to each other.

[0022] In this embodiment, the first support plate 105 and the second support plate 106 are supported by the rotating shaft. At the same time, when the anti-slip pad 104 contacts the ground, the first support plate 105 and the second support plate 106 are unfolded until they are tightly fitted to the ground. The first support plate 105 and the second support plate 106 both rotate around the axis of the rotating shaft. At the same time, the first support plate 105 and the second support plate 106 can increase the contact area with the ground to improve the support stability.

[0023] Furthermore, the rotating shaft includes a shaft body 107, a side plate 108 and a rib plate 109. The number of the side plates 108 is two groups. The two groups of side plates 108 are respectively fixedly connected to the output end of the hydraulic cylinder 102 and are respectively located at the lower end of the hydraulic cylinder 102. The two ends of the shaft body 107 are respectively fixedly connected to the corresponding side plates 108 and are located between the two groups of side plates 108. The number of the rib plates 109 is two groups. Each group of the rib plates 109 is respectively fixedly connected to the corresponding side plate 108 and the hydraulic cylinder 102, and are respectively located on one side of the corresponding side plate 108 and the hydraulic cylinder 102.

[0024] In this embodiment, the shaft body 107 is fixed to the lower end of the hydraulic cylinder 102 through two groups of side plates 108, and the first support plate 105 and the second support plate 106 are installed by the shaft body 107. The first support plate 105 and the second support plate 106 rotate around the shaft body 107 as the axis, and the ribs 109 reinforce the load of the side plates 108 to improve the load capacity of the side plates 108.

[0025] Furthermore, each group of the auxiliary components includes an auxiliary frame 110, a spring 111, a supporting column 112 and a buffer gasket 113. The auxiliary frame 110 is fixedly connected to the hydraulic cylinder 102 and is located on one side of the hydraulic cylinder 102. One end of the spring 111 is embedded in the interior of the auxiliary frame 110, and the other end of the spring 111 is adapted to the support assembly. The supporting column 112 is fixedly connected to the auxiliary frame 110 and is located at the lower end of the auxiliary frame 110. The buffer gasket 113 is fixedly connected to the supporting column 112 and is located at the lower end of the supporting column 112.

[0026] In this embodiment, the auxiliary frame 110 installs and fixes the spring 111 and the supporting column 112, and the spring 111 connects the auxiliary frame 110 and the support assembly. The spring 111 facilitates the resetting of the support assembly. The buffer gasket 113 is installed to the lower end of the supporting column 112. The buffer gasket 113 contacts the support assembly to avoid hard contact. The supporting column 112 and the buffer gasket 113 make the support assembly parallel to the ground, so that the support assembly can achieve optimal support strength.

[0027] Furthermore, each group of the support mechanism also includes a waterproof cover 114 and a mounting bar 115. The number of the mounting bars 115 is two groups. The two groups of mounting bars 115 are respectively fixedly connected to the waterproof cover 114 and are respectively located on both sides of the waterproof cover 114. The waterproof cover 114 is arranged on one side of the vehicle body 101, and the waterproof cover 114 covers the hydraulic cylinder 102 and the side mounting plate 103.

[0028] In this embodiment, the waterproof cover 114 is installed to one side of the hydraulic cylinder 102 through the installation bar 115, and the hydraulic cylinder 102 is covered. The protection of the waterproof cover 114 can reduce the erosion of rainwater on the side mounting plate 103, and extend the service life and usage strength of the side mounting plate 103.

Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the utility model.
