[0036] 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.
[0037] 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.
[0038] The embodiments described in this specification will now be described in detail.
[0039] Reference Figure 1 and Figure 2 As shown, this application discloses a translation frame, which includes a fixed frame 10, a sliding frame 20, and a locking mechanism 30. The sliding frame 20 is arranged above the fixed frame 10, and the sliding frame 20 can slide relative to the fixed frame 10 to adjust the retraction and deployment states of the translation frame.
[0040] In this embodiment, linear guide rails 14 are provided on both sides of the top of the fixed frame 10 along the sliding direction, and a slider 26 that cooperates with the linear guide rails 14 is provided at the bottom of the sliding frame 20. Thus, by sliding the slider 26 relative to the linear guide rails 14, 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 slider 26 and the linear guide rails 14 greatly reduces the shaking and wobbling phenomena between the fixed frame 10 and the sliding frame 20.
[0041] Referring again to the reference figure, the fixed frame 10 includes a front crossbar 11, a rear crossbar 12, two side bars 13, an optical axis 16, a shock-absorbing pad 17, an elastic element 18, and a positioning block 19. The two side bars 13 are connected to the two ends of the front crossbar 11 and the rear crossbar 12 and form the fixed frame 10, which has a square structure.
[0042] The optical axis 16 is connected between the front crossbar 11 and the rear crossbar 12, and is parallel to the sliding direction. In this embodiment, there are two optical axes 16, which are arranged symmetrically about the center of the fixed frame 10.
[0043] The shock-absorbing pads 17 are set at both ends of the optical axis 16 and fixed on the front crossbar 11 and the rear crossbar 12. In this way, the sliding frame 20 can avoid colliding with the front crossbar 11 and the rear crossbar 12 during the sliding process.
[0044] The positioning block 19 is fixed to the rear crossbar 12, and one end of the elastic element 18 is sleeved on the positioning block 19. In some embodiments, the elastic element 18 is a spring, an elastic rubber ring, a metal sheet, etc.
[0045] The sliding frame 20 includes a mounting base 21, a front sliding rod 22, a rear sliding rod 23, and two side sliding rods 24. The two side sliding rods 24 are connected to the two ends of the front sliding rod 22 and the rear sliding rod 23 and form the sliding frame 20. The sliding frame 20 has a square structure.
[0046] In this embodiment, the sliding frame 20 and the fixed frame 10 are the same size, thus minimizing the overall space occupied by the translation frame and maximizing the structural rigidity when the translation frame is in the retracted state.
[0047] The sliding crossbar 25 is disposed on the sliding frame 20 and perpendicular to the sliding direction. In this embodiment, there are two sliding crossbars 25, 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 position where the sliding frame 20 slides out is the front part.
[0048] The guide block 27 is fixed to the sliding crossbar 25, and the guide block 27 has a through hole through which the optical axis 16 passes. In this way, the guide block 27 and the sliding crossbar 25 are strictly restricted to linear movement only on the axis of the optical axis 16, ensuring the linearity of the movement of the sliding frame 20.
[0049] When the sliding frame 20 is in the retracted state, the other end of the elastic element 18 abuts against the guide block 27. 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 elastic element 18 and the limiting slider 26.
[0050] The sliding crossbar 25 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 25.
[0051] By extending one end of the first connecting plate toward the fixed frame 10, the sliding crossbar 25 fixed on the angle iron is lowered, so that the space above the sliding crossbar 25 and the fixed frame 10 can accommodate other components, thus avoiding interference between the sliding crossbar 25 and other components.
[0052] The pulley 15 is fixed to the top of the fixed frame 10 and located at the front end of the linear guide rail 14. The pulley 15 rotates and engages 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 15 can assist the movement of the sliding frame 20. On the other hand, when the translation frame is in the unfolded state as shown in the figure, the pulley 15 can provide a support point for the sliding frame 20, ensuring the structural stability when the user acts on the sliding frame 20.
[0053] Please refer to the reference again. Figure 3 and Figure 4 As shown, the locking mechanism 30 includes a positioning rod 31, a bushing 32, and a limiting ring 33.
[0054] The positioning rod 31 includes a main body 311 and a positioning part 312, with the main body 311 fixed to the sliding frame 20. In this embodiment, the mounting base 21 is fixed to the sliding rear rod 23, and the mounting base 21 is provided with a threaded hole 211, while the main body 311 is provided with a threaded groove 315 that matches the threaded hole 211. By cooperating with the threaded hole 211 and the threaded groove 315, the depth to which the positioning rod 31 penetrates into the bushing 32 can be adjusted.
[0055] The positioning part 312 is provided with a positioning groove 313. The positioning groove 313 is an annular groove arranged radially along the positioning rod 31.
[0056] The bushing 32 is fixed on the rear crossbar 12. The bushing 32 has an axially penetrating mounting hole 321 and a slot 322. The slot 322 is connected to the mounting hole 321, so that the limiting ring 33 can pass through the connecting part and engage with the positioning groove 313.
[0057] To facilitate smoother entry of the positioning rod 31 into the mounting hole 321, a guide portion 314 is provided at the end of the positioning part 312 away from the main body part 311. The outer radial direction of the guide portion 314 gradually increases towards the side closer to the main body part 311. This improves the assembly efficiency and reliability of the positioning rod 31 when it enters the mounting hole 321, preventing jamming and scratching problems caused by the edges.
[0058] The limiting ring 33 is fixed within the slot 322. The limiting ring 33 includes a straight segment 331 and an arc segment 332. An opening 333 is formed between the straight segment 331 and the arc segment 332. In this embodiment, the limiting ring 33 is elastic. In some embodiments, the limiting ring 33 is made of a spring, an elastic rubber ring, a metal spring, etc.
[0059] The arc segment 332 is held in the slot 322, and the straight segment 331 is located in the mounting hole 321. When the translation frame is in the retracted state, the positioning part 312 is inserted into the mounting hole 321, and the straight segment 331 is engaged in the positioning groove 313 to fix the positioning rod 31 in the bushing 32, thus realizing the locking of the translation frame and avoiding the problem of the sliding frame 20 sliding out after accidental contact. This allows the sliding function of the sliding frame 20 to be actively controlled by the user, improving the user experience of the translation frame.
[0060] When the translation frame needs to be in the retracted state, the user first moves the sliding frame 20 towards the side closer to the fixed frame 10. Then, the sliding frame 20 drives the positioning rod 31 to move, causing the positioning rod 31 to enter the bushing 32. Finally, the limiting ring 33 on the bushing 32 is engaged in the positioning groove 313, restricting the relative sliding between the sliding frame 20 and the fixed frame 10, thus locking the sliding frame 20 and the fixed frame 10 together.
[0061] When the translation frame needs to be deployed, the user first applies a force to the translation frame in the sliding direction of the sliding frame 20. Then, the force acts on the sliding frame 20, forcing the positioning rod 31 to compress the limiting ring 33, causing it to elastically deform, thus disengaging the positioning rod 31 from the bushing 32, and unlocking the sliding frame 20 and the fixed frame 10.
[0062] 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.
