[0043] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0044] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0045] The embodiments described in this specification will now be described in detail.
[0046] Reference Figures 1-3 As shown, this application discloses a translation frame, which includes a fixed frame 10, a sliding frame 20, pulleys 30, and a locking structure 40. The fixed frame 10 and the sliding frame 20 interact and cooperate. When the translation frame is in the retracted state, the sliding frame 20 is located directly above the fixed frame 10. When the translation frame is in the extended state, the sliding frame 20 is partially located above the fixed frame 10.
[0047] Along the sliding direction, linear guide rails 11 are provided on both sides of the top of the fixed frame 10, and sliders 21 that cooperate with the linear guide rails 11 are provided at the bottom of the sliding frame 20. Thus, by sliding the sliders 21 relative to the linear guide rails 11, the sliding frame 20 can be moved relative to the fixed frame 10, allowing the translation frame to have both a retracted and an extended state. The small clearance between the sliders 21 and the linear guide rails 11 greatly reduces the shaking and wobbling phenomena between the fixed frame 10 and the sliding frame 20.
[0048] Please refer to the reference again. Figure 4 As shown, the fixed frame 10 includes a front crossbar 12, a rear crossbar 13, two side bars 14, an optical axis 15, a shock-absorbing pad 16, a first elastic element 17, and a positioning block 18. The two side bars 14 are connected to the two ends of the front crossbar 12 and the rear crossbar 13 and form the fixed frame 10, which has a square structure.
[0049] The optical axis 15 is connected between the front crossbar 12 and the rear crossbar 13, and is parallel to the sliding direction. In this embodiment, there are two optical axes 15, which are arranged symmetrically about the center of the fixed frame 10.
[0050] The shock-absorbing pads 16 are set at both ends of the optical axis 15 and fixed on the front crossbar 12 and the rear crossbar 13. In this way, the sliding frame 20 can avoid collision with the front crossbar 12 and the rear crossbar 13 during the sliding process.
[0051] The positioning block 18 is fixed to the rear crossbar 13, and one end of the first elastic element 17 is sleeved on the positioning block 18. In some embodiments, the first elastic element 17 is a spring, an elastic rubber ring, a metal sheet, etc.
[0052] The sliding frame 20 includes sliding main rods 22 and sliding crossbars 23. There are four sliding main rods 22, which are connected end to end to form the sliding frame 20. The sliding frame 20 has a square structure.
[0053] In this embodiment, the sliding frame 20 and the fixed frame 10 are the same size, thereby minimizing the overall space occupied by the translation frame and maximizing the structural rigidity when the translation frame is in the retracted state.
[0054] The sliding crossbar 23 is disposed on the sliding frame 20 and perpendicular to the sliding direction. In this embodiment, there are two sliding crossbars 23, one located in the middle of the sliding frame 20 and the other located in the rear of the sliding frame 20. The middle and rear parts mentioned here refer to the sliding direction of the sliding frame 20, and the front part is the position where the sliding frame 20 slides out.
[0055] The guide block 24 is fixed to the sliding crossbar 23, and the guide block 24 is provided with a through hole for the optical axis 15 to pass through. In this way, the guide block 24 and the sliding crossbar 23 are strictly restricted to linear movement only on the axis of the optical axis 15, ensuring the linearity of the movement of the sliding frame 20.
[0056] When the sliding frame 20 is in the retracted state, the other end of the first elastic element 17 abuts against the guide block 24. In this way, while absorbing shock, the movement path of the fixed frame 10 and the sliding frame 20 is restricted by the direct contact between the first elastic element 17 and the limiting slider 21.
[0057] The sliding crossbar 23 is fixed to the movable frame by an angle iron. The angle iron includes a first connecting plate and a second connecting plate that are perpendicular to each other. One end of the first connecting plate is fixed to the movable frame, and the other end extends toward the fixed frame 10. One end of the second connecting plate is connected to the other end of the first fixed plate, and the other end of the second connecting plate is connected to the sliding crossbar 23.
[0058] By extending one end of the first connecting plate toward the fixed frame 10, the sliding crossbar 23 fixed on the angle iron is lowered, so that the space above the sliding crossbar 23 and the fixed frame 10 can accommodate other components, thus avoiding interference between the sliding crossbar 23 and other components.
[0059] The pulley 30 is fixed to the top of the fixed frame 10 and located at the front end of the linear guide rail 11. The pulley 30 rotates in conjunction with the bottom wall of the sliding frame 20. On the one hand, when the sliding frame 20 moves forward, the rolling of the pulley 30 assists in the movement of the sliding frame 20; on the other hand, when... Figure 2 As shown, when the translation frame is in the unfolded state, the pulley 30 can provide a support point for the sliding frame 20, ensuring the structural stability when the user acts on the sliding frame 20.
[0060] Please refer to the reference again. Figures 5-7 As shown, the locking structure 40 includes a limiting shaft 41, a locking cap 42, a stop block 43, a limiting boss 44, and a sliding stop bar 45. One end of the limiting shaft 41 is fixed to the rear crossbar 13, and the other end points to the center of the fixing frame 10 and is provided with a locking cap 42. In this embodiment, the locking cap 42 is fixed to the end of the limiting shaft 41 by screws.
[0061] The radial dimension of the cap 42 gradually increases towards the side closer to the stop 43. This allows the sliding stop 45 to move smoothly from the end with the smaller radial dimension to the other end.
[0062] The stop block 43 is movably fitted onto the limiting shaft 41. When the translation frame is in the retracted state, a limiting groove is formed between the stop block 43 and the locking cap 42. When the translation frame is in the extended state, the stop block 43 and the locking cap 42 abut against each other. The limiting boss 44 is fixed on the limiting shaft 41 and is located on the side of the stop block 43 away from the locking cap 42, so as to limit the movement path of the stop block 43 on the limiting shaft 41.
[0063] The radial dimension of the stop block 43 gradually increases towards the side closer to the cap 42. Thus, as the sliding stop lever 45 moves from the end with the larger radial dimension to the other end, it can act on the stop block 43 and push the stop block 43 to move.
[0064] A sliding stop 45 is positioned above the limiting shaft 41 and can move up and down. The end of the sliding stop 45 closest to the limiting shaft 41 has a guide surface 451 and a limiting surface 452, with the guide surface 451 and the limiting surface 452 facing each other. In this embodiment, the guide surface 451 is an inclined surface.
[0065] The surface of the stop block 43 near the cap 42 has a groove 431. The radial dimension of the opening of the groove 431 matches the radial dimension of the cap 42 at its maximum. When the sliding stop rod 45 moves from the end of the stop block 43 with the larger radial dimension to the other end, it can push the stop block 43 towards the cap 42, allowing the cap 42 to be placed in the groove 431. At this time, the limiting groove between the stop block 43 and the cap 42 disappears. When the sliding frame 20 is pushed outward, the sliding stop rod 45 can directly transition from the stop block 43 to the cap 42 without falling into the limiting groove and getting stuck.
[0066] In this embodiment, the cap 42, stop 43, limiting boss 44, and sliding stop 45 are made of iron, resulting in high structural strength. In another embodiment, the cap 42, stop 43, limiting boss 44, and sliding stop 45 are made of polyurethane, which reduces friction noise when the limiting boss 44 contacts the cap 42 and stop 43.
[0067] When the sliding frame 20 is in the retracted state, the limiting surface 452 of the sliding stop bar 45 abuts against the cap 42, and the guiding surface 451 abuts against the stop block 43, thereby locking the sliding stop bar 45 in the limiting groove, thus locking the sliding frame 20, allowing the sliding function to be actively controlled by the user, eliminating safety hazards and enhancing the safety of the translation frame.
[0068] A guide plate 46 is fixedly connected to the top of the sliding crossbar 23. The guide plate 46 has an inverted U-shaped structure, and both ends of the U-shaped structure are fixed to the sliding crossbar 23, so that the guide plate 46 and the sliding crossbar 23 together form a limiting area. The main body of the sliding stop bar 45 is placed in the limiting area. One end of the sliding stop bar 45 passes through the guide plate 46 to lock the sliding frame 20. The other end passes through the sliding crossbar 23.
[0069] A limiting piece 47 is fixed on the sliding stop 45 and placed within the limiting area. A second elastic element 48 is sleeved on the surface of the sliding stop 45. One end of the second elastic element 48 abuts against the limiting piece 47, and the other end abuts against the inner wall of the guide piece 46. The sliding stop 45 can move up and down due to the elastic force of the second elastic element 48. In some embodiments, the second elastic element 48 is a spring, an elastic rubber ring, a metal spring, etc.
[0070] When the translation frame needs to be adjusted to the retracted state, first push the sliding frame 20 in the retracting direction. Then, the sliding stop 45 contacts the outer wall of the cap 42, and the sliding stop 45 rises upward. Next, the guide surface 451 of the sliding stop 45 contacts the stop block 43, and pushes the stop block 43 towards the limiting boss 44 until the stop block 43 abuts against the limiting boss 44 and cannot move. Finally, under the elastic action of the second elastic element 48, the sliding stop 45 is inserted into the limiting groove between the cap 42 and the stop block 43. The limiting surface 452 of the sliding stop 45 abuts against the cap 42, and the guide surface 451 abuts against the stop block 43, positioning the sliding stop 45 in the limiting groove to achieve locking, and the translation frame is adjusted to the retracted state.
[0071] When the translation frame needs to be deployed, first push the sliding frame 20 in the retraction direction, and then push it in the deployment direction. Specifically, first push the sliding frame 20 in the reverse retraction direction. At this time, the guide surface 451, blocked by the stop block 43, causes the sliding stop bar 45 to rise until the bottom of the sliding stop bar 45 contacts the outer wall of the stop block 43. Then continue to push the sliding frame 20 in the retraction direction. The sliding stop bar 45 simultaneously pushes the stop block 43 closer to the locking cap 42 until the locking cap 42 sinks into the recess 431.
[0072] Then push the sliding frame 20 in the unfolding direction. Specifically, first, the sliding frame 20 slides along the unfolding direction, and the bottom of the sliding stop 45 contacts the outer wall of the stop block 43 and the outer wall of the cap 42 in sequence, until the sliding stop 45 disengages from the cap 42. At this time, the sliding frame 20 and the fixed frame 10 are unlocked. Finally, continue to move the sliding frame 20 along the unfolding direction, and the translation frame is adjusted to the unfolded state.
[0073] It should be noted that the above-mentioned retraction direction and unfolding direction are both along the sliding direction. The retraction direction refers to the sliding frame 20 moving towards the fixed frame 10, and the unfolding direction refers to the sliding frame 20 moving away from the fixed frame 10.
[0074] This application also discloses a seating arrangement, which includes a seating body and a sliding frame, with a fixed frame 10 fixedly connected to the seating body. The seating arrangement referred to herein can be a sofa, bed, chair, etc., and is not specifically limited herein.
[0075] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
