Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a column protective curtain mechanism for a pelvic mechanism of a lower limb rehabilitation robot. Background Art
[0002] The lifting mechanism in the column of some lower limb rehabilitation robots is used to drive the longitudinal movement of the pelvic mechanism. The lifting mechanism is generally composed of a screw rod, a guide rail and a sliding member arranged on the guide rail and connected to the pelvic mechanism. The sliding member is threadedly installed with the screw rod. When the screw rod is driven to rotate, the sliding member is driven to slide longitudinally on the guide rail, thereby realizing the longitudinal movement of the pelvic mechanism. The guide rail and the screw rod are exposed to the outside without good shielding, which poses certain safety hazards. According to the new version of the standard, the capture area needs to be designed, that is, dynamic shielding is required.
[0003] The existing dynamic occlusion is achieved through an accordion cover, but the accordion cover is too large and ugly, which affects the appearance. At the same time, it will make friction sounds over time, affecting the user experience. Summary of the invention
[0004] In view of the above-mentioned problems existing in the existing dynamic shading, the present invention aims to provide a protective curtain mechanism for the columns of the pelvic mechanism of a lower limb rehabilitation robot, which has high safety, improves overall aesthetics and optimizes user experience.

[0011] As a further improvement and optimization of this solution, it also includes a limit buffer structure, which includes a blocking plate and a blocking buffer block. The blocking plate is installed between the two mounting seats, and the blocking buffer block is installed on the side of the blocking plate close to the sliding member for longitudinal limitation with the sliding member.
[0012] As a further improvement and optimization of this solution, the guide rod is located on the outside of the protective curtain, and the limiting buffer structure is located on the inside of the protective curtain.
[0013] As a further improvement and optimization of this solution, the blocking buffer block is made of rubber material.
[0014] As a further improvement and optimization of this solution, the blocking buffer block and the blocking plate are fixed by screws.

[0019] Compared with the prior art, the above technical solution has the following positive effects:
[0020] (1) In the utility model, when the sliding member slides upward, the protective curtain in the upper shielding assembly is automatically reeled in as the winding spring drives the reel to rotate, and the protective curtain in the lower shielding assembly is unreeled as the sliding member pulls. When the sliding member slides downward, the protective curtain in the upper shielding assembly is unreeled as the sliding member pulls, and the protective curtain in the lower shielding assembly is automatically reeled in as the winding spring drives the reel to rotate, thereby achieving a dynamic shielding effect on the guide rails and the longitudinal screw rods in the lifting mechanism, which not only prevents people from reaching into the guide rails and the longitudinal screw rods, thereby improving safety in use, but also improves the overall aesthetics and avoids noise caused by long-term use.
[0021] (2) In the present invention, when the sliding member shows an excessive tendency to rise or fall, the buffer block and the sliding member are blocked to limit the longitudinal position of the sliding member to prevent the sliding member from continuing to rise or fall, thereby preventing the sliding member from rising or falling excessively and affecting the safety of use.

Figure 1-4As shown, a preferred embodiment of a protective curtain mechanism for the column of the pelvic mechanism of a lower limb rehabilitation robot is shown, which is used to shield the lifting mechanism 2 arranged on the column. The lifting mechanism 2 includes a guide rail (not shown in the figure), a longitudinal screw rod (not shown in the figure) and a sliding member 21 arranged on the column.

The coil spring 35 is arranged in the mounting cavity. The coil spring 35 is sleeved and connected to the outside of the reel 32 for providing rotational torque to the reel 32.
[0042] Furthermore, as a preferred embodiment, the cover plate 36 and the mounting seat 31 are fixed by screws.
[0043] Further, as a preferred embodiment, the guide rod 37 is arranged parallel to the reel 32 .
