Description

Double-power-assisted jacking mechanism Technical Field The application relates to the technical field of a lift-up structure of a motor home, in particular to a double-power-assisted lift-up mechanism. Background At present, a motor home is a special vehicle integrating running and living functions, most motor home (such as C-shaped self-driving motor home) has the problem of small movable space due to fixed carriage size, and the existing lifting motor home on the market is characterized in that a roof can be lowered during running, running wind resistance is reduced, overhigh is avoided, the roof can be lifted during living, and longitudinal movable space is lifted. In the prior art, chinese patent document 1 with publication number of CN218316439U discloses a motor home flat-top lifting support mechanism, which comprises an upper guide rail, a lower guide rail, a gas spring assembly and an electric push rod, wherein an X-shaped scissor type lifting support is arranged between the upper guide rail and the lower guide rail, the gas spring assembly is arranged on the lower guide rail and is positioned on the X-shaped scissor type lifting support, the electric push rod is arranged on the lower guide rail and is positioned below the X-shaped scissor type lifting support, and the gas spring assembly and the electric push rod are connected with the rolling end of the X-shaped scissor type lifting support to provide horizontal assistance for lifting of the X-shaped scissor type lifting support. Chinese patent document 2 with publication number CN219056093U discloses an electric motor home lifting mechanism with power assistance, which combines a gas spring assembly and an electric push rod to push an X-shaped scissor bracket, and utilizes the power assistance of the gas spring and the thrust of the electric push rod to realize the electric lifting of the car roof. However, in the above patent document, only one gas spring assembly is provided to assist the power, and the single gas spring assembly has a limited supporting force, and the driving force demand for the electric putter is large in the initial ascent stage. In addition, in the document 1, the gas spring assembly only provides assistance when the initial rising needs to overcome dead points, the subsequent rising and falling completely depend on the driving of the electric push rod, the structure is easy to damage while the cost is increased, the installation position of the gas spring assembly needs to be reserved in the lower guide rail, the length is longer than that of the upper guide rail, the occupied space is large, and the application force of the gas spring assembly and the electric push rod is unbalanced in the document 2, so that the inclined struts of the bracket are stressed differently, and the lifting stability is influenced. Disclosure of utility model The application provides a double-power-assisted jacking mechanism which at least partially solves the technical problems. The application provides a double-power-assisted jacking mechanism, which adopts the following technical scheme: The double-power-assisted jacking mechanism comprises a lifting assembly, a power-assisted assembly and a driving assembly, wherein the lifting assembly comprises a first bracket, a second bracket, a first inclined bracket and a second inclined bracket which are hinged in a crossed manner; One end of the first inclined support is rotationally connected with the first support, the other end of the first inclined support moves linearly along the second support, one end of the second inclined support is rotationally connected with the second support, the other end of the second inclined support moves linearly along the first support, The power assisting component comprises a first power assisting piece and a second power assisting piece, and the first power assisting piece and the second power assisting piece are respectively positioned at two sides of a rotation axis of a hinge point of the first inclined bracket and the second inclined bracket; The two ends of the first power assisting piece are respectively connected with the first inclined bracket and the second inclined bracket in a rotating way; Two ends of the second power assisting piece are respectively connected with the first inclined bracket and the second inclined bracket in a rotating way; The driving component is arranged on the second bracket and is connected with the other end of the first inclined bracket. By adopting the technical scheme, when the lifting jack is used, either the first bracket or the second bracket is used as the bottom bracket, the driving assembly pushes the first inclined bracket to move along the second bracket when the lifting jack is lifted, the moving end of the first inclined bracket is close to the rotating end of the second inclined bracket, so that the crossing angle of the first inclined bracket and the second inclined bracket is changed, the first bracket is dr
