[0034] Embodiment 1

[0035] like Figures 1 to 4 As shown in the figure, a guide module is provided in this embodiment for limiting the translation and flipping of the cargo rack 800 of the logistics vehicle. The guide module includes two guide brackets 100, which are symmetrically arranged on the chassis platform 900 of the logistics vehicle in parallel along the width direction of the logistics vehicle. A mounting member 130 is arranged at the bottom of the guide bracket 100 for fixing the guide bracket 100 to the chassis platform 900; grooves 101 are provided on the opposite sides of the two guide brackets 100 along the direction of the vehicle body, and the lower side walls of the grooves 101 are The groove bottom of the groove 101 is used to provide a translation path for the rotating shaft part of the cargo rack 800 and to respectively abut the ends of the two ends of the rotating shaft. The groove bottom can limit the cargo rack 800 in the vehicle width direction; the groove 101 is formed with a first limit stopper 110 at the end close to the rear of the logistics vehicle, which improves the structural strength of the guide bracket 100. When the cargo rack 800 translates to the extreme position and flips over, the first limit stopper 110 can prevent the rotating shaft part from detaching from the end of the groove 101 close to the rear of the vehicle and abut against the supporting rotating shaft part to assist the flipping of the cargo rack 800.

[0036] Since the guide bracket 100 has a certain length, in order to further stabilize the installation of the guide bracket 100 and reduce the risk of its deformation, a plurality of supporting members 140 are welded between the guide bracket 100 and the mounting member 130. The plurality of supporting members 140 are evenly arranged at preset distances, thereby improving the supporting strength of the guide bracket 100 and extending the service life of the guide module.

[0037] Specifically, the mounting member 130 is provided with an oblong waist-shaped hole 131, and the guide module includes a threaded connector, which can be screwed with the chassis platform 900 of the logistics vehicle through the oblong waist-shaped hole 131, which is convenient for installation. The mounting member 130 can be translated left and right to flexibly adjust and find a suitable installation position and fix it. When the rotating shaft needs to be installed on the guide module, the connection assembly of the mounting member 130 can be loosened by the threaded connector, so that the two mounting members 130 are separated from each other, the rotating shaft is arranged in place along the width direction of the vehicle, and both ends are simultaneously inserted into the groove 101, and then the mounting member 130 is brought closer and fixed. For example, sometimes there is a lack of extra adjustment space on the outside of the guide module on the chassis platform 900, and the rotating shaft cannot be stably installed and arranged from the width direction of the vehicle. It can also be embedded from the opening of the groove 101 close to the front end of the logistics vehicle. The installation method of the rotating shaft is flexible and is not limited by the chassis platform 900.

[0038] Optionally, a second limit stopper is formed at one end of the groove 101 close to the front of the logistics vehicle, and the second limit stopper can prevent the rotating shaft from detaching from the end of the groove 101 close to the front of the logistics vehicle, and at the same time, further improve the structural strength of the guide bracket 100.

[0039] Embodiment 2

It can be understood that the width of the groove 101 needs to be slightly larger than the outer diameter of the bearing roller 220, and the bearing roller 220 rolls against the lower side wall of the groove 101, and the bearing roller 220 and the upper side wall of the groove 101 have an assembly gap of 0.5 mm to 1 mm.

[0042] Furthermore, a spacer 240 is sandwiched between the bearing roller 220 and the bearing limiter 230 on either side, and the two ends of the spacer 240 respectively abut against the inner ring of the bearing roller 220 and the bearing limiter 230 to protect the rolling of the bearing roller 220 from being affected by the bearing limiter 230. Without affecting the operation of the bearing roller 220, the spacer 240 has a certain width for adjusting the installation gap between the bearing limiter 230 and the top of the groove 101 to ensure that the fixed shaft 200 can neither detach from the groove 101 along the vehicle width direction nor collide with the top of the groove 101.

[0043] In this embodiment, a limiting retaining ring 250 is respectively provided on the side where the bearing roller 220 and the bearing limit member 230 are away from each other, and the limiting retaining ring 250 is fixedly sleeved on the fixed shaft 200. The two limiting retaining rings 250 can ensure that the bearing roller 220, the spacer 240 and the bearing limit member 230 sleeved on the fixed shaft 200 are tightly abutted, preventing the bearing roller 220 and the bearing limit member 230 from unnecessary axial movement along the fixed shaft 200, thereby avoiding affecting the assembly effect of the flip auxiliary guide device.

[0044] Exemplarily, a circle of anti-friction protrusions is provided on the side of the bearing limiter 230 close to the bearing roller 220, and the diameter of the anti-friction protrusions is consistent with the slot width of the groove 101, which can further protect the rolling between the sliding module and the guide module and reduce the friction between the bearing limiter 230 and the guide bracket 100.

[0045] Optionally, the carrier connecting member 210 is rotatably connected to the fixed shaft 200 via a bearing member, the inner ring of the bearing member is fixedly connected to the fixed shaft 200, the outer ring of the bearing member is fixedly connected to the carrier connecting member 210, and the outer ring of the bearing member is rotatably connected coaxially with the inner ring of the bearing roller 220, which can support the carrier connecting member 210, reduce the friction coefficient during its movement, and ensure the rotation effect of the structure.
