Problems solved by technology

[0004] However, the above-mentioned structure not only has a too small expansion and contraction range, which leads to its weak ability to overcome obstacles and climb ladders, but also has a slow expansion and adjustment speed, which leads to more time spent when it overcomes obstacles and climbs ladders.

Embodiment Construction

[0022] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0023] Such as Figure 1-4 As shown, a high-folding fast telescopic support cylinder includes several sleeves that are fitted in sequence and slide and fit with each other. The sleeves include an upper sleeve 1, several middle sleeves, and a lower sleeve 2; A scissors-type linkage mechanism 3 is arranged inside the tube, one end of the scissors-type linkage mechanism 3 is connected to the lower sleeve 2, and the other end extends out of the upper sleeve 1, and is connected with a driving mechanism 4 for driving it to expand and contract.

[0024] Wherein, the scissor linkage mechanism 3 includes several scissor units, and each scissor unit includes a first articulated rod 301 and a second articulated rod 302 that are arranged crosswise and hinged, and the adjacent scissor units are connected by the first hinged rod 302. The hinged rod 301 and the second hin...

Abstract

A high-folding rapid telescopic supporting cylinder is characterized in that a scissor-fork type connecting rod mechanism is arranged in sleeves, one end of the scissor-fork type connecting rod mechanism is connected with the lower sleeve, and the other end of the scissor-fork type connecting rod mechanism extends out of the upper sleeve and is connected with a driving mechanism for driving the scissor-fork type connecting rod mechanism to stretch and retract. The high-folding rapid telescopic supporting cylinder has the advantages that the scissor-fork type connecting rod mechanism has better telescopic adjusting capacity and higher telescopic adjusting speed; the scissor-fork type connecting rod mechanism arranged in the sleeves which are in sliding fit with each other in a sleeved mode, and the scissor-fork type connecting rod mechanism and the sleeves are combined, so that the telescopic amplitude and the telescopic speed are ensured, the strength capability is ensured, and supporting is more stable and firmer.

Description

technical field [0001] The invention relates to a telescopic support cylinder, in particular to a high-folding and fast telescopic support cylinder. Background technique [0002] The applicant once invented and created an obstacle-crossing wheelchair, and applied for an invention patent (the application publication number is CN106137582A). The obstacle-crossing wheelchair can realize up and down slopes, climb ladders, and cross obstacles through the reciprocating swing and stretching of the walking feet at the bottom. things and other functions. [0003] Its walking legs are composed of an upper leg and a lower leg, and are driven by a servo motor and a ball screw to realize its telescopic support function. [0004] However, the above-mentioned structure not only has a too small range of expansion and contraction, which leads to its weak ability to overcome obstacles and climb ladders, but also has a slow expansion and adjustment speed, which leads to more time spent when i...
