DETAILED DESCRIPTION

[0021] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application. In the description of the present application, it should be understood that the terms "upper", "lower", "front", "upper surface" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore should not be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be understood as limiting the present application.

[0022] Please refer to Figures 1-8 The auxiliary support mechanism for the motorized platform comprises a base 1, both sides of the base 1 are provided with a shaft pin seat 2, and the shaft pin seat 2 is arranged on the upper surface of the base 1; the shaft pin seat 2 is connected with a support assembly 3 provided with a shaft pin, the support assembly 3 comprises a support arm 30, the support arm 30 is connected with the shaft pin hole 6 provided with a hinged block 36 on the shaft pin seat 2; the support arm 30 is connected with a linkage frame 33 provided with a shaft pin, the linkage frame 33 is connected with a telescopic piece 32 provided with a shaft pin, and the other end of the telescopic piece 32 is connected with a fixed seat 5 provided with a shaft pin on the base 1.

[0023] In summary, since the hinge block 36 is connected with the shaft pin seat 2 via the shaft pin, and the telescopic piece 32 is used to drive the support arm 30 to rotate on the shaft pin seat 2, the unfolding or folding of the support arm 30 can be completed. Since the shaft pin seat 2 is located on the upper surface of the base 1, the telescopic piece 32 can completely fold the support arm 30 to the upper surface of the base 1 after being retracted. Therefore, the support arm 30 can support the vehicle body after being unfolded, and the space occupied by the support arm 30 on the side of the vehicle body can be effectively solved after being folded. In particular, since the telescopic mechanism only needs one telescopic piece 32 to complete the unfolding and folding of the support arm 30, the support mechanism is simplified, the device is easy and fast to operate, the reliability and maneuverability of the device are improved.

[0024] Further, the linkage frame 33 is further provided with a connecting rod 37. The connecting rod 37 is connected with the round hole 7 located below the shaft pin seat 2 via the shaft pin, and the other end of the connecting rod 37 is connected with the linkage frame 33 via the shaft pin. Specifically, the two ends of the linkage frame 33 are provided with the pin shaft 34. The lower end of the linkage frame 33 is connected with the support arm 30 via the pin shaft 34, and the upper end of the linkage frame 33 fixes the working part of the telescopic piece 32 and the connecting rod 37 on the linkage frame 33 via the pin shaft 34. Therefore, the main function of the connecting rod 37 is to ensure that the telescopic piece 32 is not at the dead point position in the retracted state, so that the support arm 30 can be smoothly unfolded and folded.

[0025] In order to ensure that the support arm 30 has reliable support ability after being unfolded, the support arm 30 is further provided with a positioning hole 35, and the positioning hole 35 is connected with the through hole 8 located below the shaft pin seat 2. Specifically, after the shaft pin passes through the through hole 8 and the positioning hole 35, one end of the support arm 30 can be fixed on the base 1, so that the stability of the connection between the support arm 30 and the base 1 is further improved, and the reliable support of the support arm 30 to the vehicle body is ensured.

[0026] In addition, since the support leg 31 is further provided at the end of the support arm 30 away from the base 1, the support leg 31 can be used to contact the ground to reliably support the other end of the support arm 30.

[0027] On the basis of the above scheme, the support arm 30 comprises a bottom plate 38 and a top plate 310, and a connecting plate 312 is arranged between the top plate 310 and the bottom plate 38; wherein both sides of the connecting plate 312 are provided with a rib plate 311, and the rib plate 311 and the connecting plate 312 are provided with a ventilation hole 39. Since the support arm 30 is composed of the bottom plate 38, the top plate 310 and the connecting plate 312, the production and processing of the support arm 30 are simple and convenient, and the structural strength of the entire support arm 30 can be improved by the arrangement of the rib plate 311, especially, the rib plate 311 and the connecting plate 312 are both provided with the ventilation hole 39, so that the wind resistance of the support arm 30 is small, thereby improving the wind resistance of the equipment.

[0028] Further, since the upper surface of the base 1 is also provided with a support 4 for supporting the support assembly 3, the support arm 30 is supported by the support 4 to ensure the stability of the support arm 30 after folding, and especially the phenomenon of sprain of the support arm 30 caused by vehicle bumping can be avoided.

[0029] Further, since the inside of the base 1 is a hollow structure, the self-weight of the base 1 can be reduced, and when the telescopic member 32 is a hydraulic oil cylinder, the related components in the hydraulic system can be installed inside to protect the parts in the hydraulic system, such as the filter 20, the one-way constant displacement hydraulic pump 21, the three-position four-way electromagnetic valve 22, the one-way speed regulating valve 23, the synchronous hydraulic motor 24, the overflow valve 25 and the one-way valve 26. In addition, the hydraulic system can be installed at the platform or the chassis according to actual needs.

[0030] As shown in the figure, the hydraulic system is composed of a hydraulic oil tank 19, a filter 20, a one-way constant displacement hydraulic pump 21, a three-position four-way electromagnetic valve 22, a one-way speed regulating valve 23, a synchronous hydraulic motor 24, an overflow valve 25, a one-way valve 26 and a telescopic member 32. Figure 8 The support arm is unfolded: the chassis engine is started, the engine drives the power take-off to operate, the power take-off drives the one-way constant displacement hydraulic pump 21 to operate, the three-position four-way electromagnetic valve 22 is powered to realize oil path switching to the telescopic member 32 extension state, the telescopic member 32 pushes the support arm 30 to the unfolded state, and the shaft pin passes through the through hole 8 and the positioning hole 35, and the unfolding action is completed.

[0031] The support arm is folded: the chassis engine is started, the engine drives the power take-off to operate, the power take-off drives the one-way constant displacement hydraulic pump 21 to operate, the three-position four-way electromagnetic valve 22 is powered to realize oil path switching to the telescopic member 32 contraction state, the telescopic member 32 pulls the support arm 30 to the folding state, and the folding action is completed.

[0032] The embodiments of the present application are described in detail in combination with the drawings, but the present application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations of the embodiments can be made without departing from the principles and spirits of the present application, and still fall within the protection scope of the present application.
