[0021] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.
[0022] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.
[0023] like Figure 1-7 As shown, a concealed footrest structure includes a seat 1 and a footrest 2. The bottom surface of the seat 1 has two seat grooves 3 with front openings. A footrest slide rod 4, which is inserted into the front opening and can slide, is provided in the seat grooves 3. The footrest slide rod 4 is provided on the extended end of the footrest slide rod 4 in the footrest 2. A footrest slide rod positioning block 5 is provided on the upper side of the seat groove 3 near the front position. The lower side of the footrest slide rod positioning block 5 has a positioning block recess 6 that fits on the outside of the footrest slide rod 4. A guide ring 7 is provided on the outside of the footrest slide rod 4 in the positioning block recess 6. A limiting protrusion 8 on the rear side of the footrest slide rod 4 cooperates with the footrest slide rod positioning block 5 to limit the maximum extension position of the footrest slide rod 4. When it is necessary to pull out the footrest to rest the feet, simply pull the footrest 2 outward so that the footrest slide rod 4 is pulled out of the seat groove 3. The extension length of the footrest 2 can be adjusted according to the actual usage length. When the foot pedal 2 is extended to its maximum length, the limiting protrusion 8 cooperates with the foot pedal slide rod positioning block 5 to prevent the foot pedal slide rod 4 from disengaging from the seat slide groove 3. The foot pedal slide rod positioning block 5 and the guide ring 7 limit the sliding direction of the seat slide groove 3 and increase the support force of the foot pedal 2.
[0024] like Figure 1-4 As shown, the positioning block recess 6 is provided with an upper guide ring positioning groove 9, and the lower side of the seat slide 3 is provided with a lower guide ring positioning groove 10. The guide ring 7 is set between the upper guide ring positioning groove 9 and the lower guide ring positioning groove 10 to better lock the guide ring 7, thereby better limiting the sliding direction of the foot pedal slide bar 4.
[0025] like Figure 1-4 As shown, the positioning block recess 6 has a limiting recess 11 on the rear side of the upper guide ring positioning groove 9, which cooperates with the limiting protrusion 8 to better prevent the foot pedal slide rod 4 from disengaging from the seat slide groove 3.
[0026] like Figure 1-7As shown, the extended ends of the two foot pedal slides 4 are connected to form a U-shaped foot pedal slide, and the foot pedal 2 is mounted on the connecting part of the U-shaped foot pedal slide. An opening and closing component connects the U-shaped foot pedal slide and the foot pedal 2, allowing the foot pedal 2 to be rotated open or folded. When it is necessary to pull out the foot pedal to rest the feet, after pulling out the foot pedal 2, it is rotated to open the foot pedal 2 for the user to place their feet. When folding, the foot pedal 2 can be folded back under the foot pedal slide 4 and pushed back under the seat 1 for storage.
[0027] like Figure 5-7As shown, the opening and closing assembly includes two rotating sleeves 12 fitted onto a U-shaped foot pedal slide rod. A sleeve 13 fitted onto the rotating sleeves 12 and capable of sliding relative to them is provided on the foot pedal 2. A stop 14 separating the two rotating sleeves 12 is provided in the middle of the sleeve 13. A rotating sleeve slide rod 15 extending outwards is provided on the side of the U-shaped foot pedal slide rod. A rotating sleeve groove 16, which cooperates with the rotating sleeve slide rod 15 and slides within the sleeve 13 as the foot pedal rotates to the open or folded position, is provided on the side of the rotating sleeve 12. An outwardly extending positioning protrusion is provided on the outer side of the rotating sleeve 12. 17. The end faces of the sleeve 13 are respectively provided with two positioning recesses 18 that cooperate with the positioning protrusions 17 and are positioned when the foot pedal 2 is rotated to the open or folded position. The inner side of the sleeve 13 is provided with an inwardly extending sleeve slide rod 19. The side of the rotating sleeve 12 is provided with a rotating sleeve guide groove 20 that cooperates with the sleeve slide rod 19, unlocking the positioning protrusions 17 from the positioning recesses 18 and guiding the rotating sleeve 12 back to the folded position when the sleeve 13 rotates to the top with the foot pedal 2. A return spring 21 is sleeved on the U-shaped foot pedal slide rod between the stop block 14 and the rotating sleeve 12. When it is necessary to open the foot pedal 2, the foot pedal 2 is rotated forward, causing the rotating sleeve 12 to rotate. Under the guidance of the positioning recesses 18, the rotating sleeve 12 moves inward, causing the positioning protrusions 17 to disengage from the positioning recesses 18, thus unlocking the sleeve. During rotation, with the cooperation of the rotating sleeve guide groove 20 and the sleeve slide rod 19, when the foot pedal 2 is rotated to the open position, the return spring 21 pushes the guide positioning protrusion 17 to move laterally and engage with the corresponding positioning recess 18. At the same time, the rotating sleeve slide rod 15 will move to the locking position of the rotating sleeve groove 16 to lock it, allowing the user to place their feet. When folding the foot pedal 2, rotate the foot pedal 2 forward to the top and then rotate it backward to fold it back to the underside of the U-shaped foot pedal slide rod. During this rotation, the foot pedal 2 drives the rotating sleeve 12 to rotate, and under the guidance of the positioning notch 18, the rotating sleeve 12 moves inward, causing the positioning protrusion 17 to disengage from the positioning notch 18 to unlock. At the same time, with the cooperation of the sleeve slide rod 19 and the rotating sleeve guide groove 20, the rotating sleeve 12 moves backward with the foot pedal 2, and the blocking return spring 21 pushes the rotating sleeve 12 to move laterally until the rotating sleeve 12 rotates back to the folded position. Under the action of the return spring 21, the guide positioning protrusion 17 moves laterally and engages with the corresponding positioning notch 18. At the same time, the rotating sleeve slide rod 15 moves to the locking position of the rotating sleeve groove 16 to lock, so that the foot pedal 2 is folded under the U-shaped foot pedal slide rod.
[0028] like Figure 5-7 As shown, the stop block 14 is provided with a stop block groove 22, and the bottom surface of the stop block groove 22 is provided with multiple buffer recesses 23. The U-shaped foot pedal slide rod is fitted with a buffer block 24 set in the stop block groove 22. The outer side of the buffer block 24 is provided with a buffer elastic protrusion 25 that cooperates with the buffer recesses 23, so as to play a role in buffering and slowing down the rotation during the rotation process.
[0029] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
