[0025] Embodiment one

[0026] In order to solve the problem that the existing six-degree-of-freedom platform is not convenient to fold and the mode is relatively complicated, the following scheme is disclosed, and the specific embodiments are as shown in Figure 1 、 Figure 2 、 Figure 5 and Figure 6 .

[0027] A folding footboard for a Stewart parallel robot six-degree-of-freedom platform, comprising a six-degree-of-freedom platform body 1 and a footboard 2, the footboard 2 is connected to one side of the six-degree-of-freedom platform body 1, and is provided with two groups, a limiting rod 9 is fixed below the one side of the six-degree-of-freedom platform body 1, a telescopic rod 7 is movably connected in the limiting rod 9, a bearing plate 12 is hinged to the front end of the telescopic rod 7, the inner side of the bearing plate 12 is hinged to the upper side of the footboard 2, a limiting groove is arranged in the limiting rod 9, and the limiting groove is slidably connected with the telescopic rod 7, and the footboard 2 and the telescopic rod 7 are connected by magnet attraction;

[0028] The width of the limiting groove is equal to the width of the telescopic rod 7, and the telescopic rod 7 can slide inside the limiting groove;

[0029] The telescopic rod 7 has sliders fixed on both sides at one end. The limiting rod 9 has grooves 11 on both sides, and the grooves 11 are slidably connected to the sliders. The outer side of the slider is fixed with a locking block 10, which plays a locking and fixing role to prevent the telescopic rod 7 from sliding out of the groove 11.

[0030] In this embodiment, during use, the telescopic rod 7 is slid into the interior of the limit rod 9 through the sliding connection between the limit rod 9 and the telescopic rod 7, and locked in place by the locking block 10 to prevent it from sliding out. At the same time, by setting a magnetic attraction structure, after the foot pedal is folded, the foot pedal 2 can be attracted to the support plate 12 to prevent it from falling and flipping down. When it is not in use and needs to be folded, the operation can be reversed.

[0031] Example 2

[0032] This embodiment differs from Embodiment 1 in that the reinforcing rib 8 provides reinforcement, thereby enhancing its load-bearing capacity. Specifically, as shown below... Figure 3 and Figure 4 As shown:

[0033] A connecting plate 3 is fixed at the bottom of the six-degree-of-freedom platform body 1 behind the foot pedal 2, and a groove 6 is provided on the inner side of the connecting plate 3. A support connecting rod 5 is hinged inside the groove 6, and a hook 4 is fixed above the support connecting rod 5. A mounting buckle 13 is fixed below the bearing plate 12, and the mounting buckle 13 is snapped together with the hook 4.

[0034] A reinforcing rib 8 is fixed between the telescopic rods 7, and the reinforcing rib 8 is composed of two sets of N-shaped combinations.

[0035] In this embodiment, the installation of reinforcing ribs 8 during use can effectively strengthen the strength between the two sets of telescopic rods 7. At the same time, through the snap-fit ​​connection between hook 4 and mounting buckle 13, and with the support of the supporting connecting rod 5, the foot pedal 2 is further reinforced and supported, preventing the foot pedal 2 from bearing relatively weak force due to being in a suspended state.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
