Description

Technical Field

[0001] This utility model relates to the field of pivot technology, and in particular to a linkage-type pivot with a foot pad reciprocating mechanism. Background Technology

[0002] Existing electronic devices, such as laptops, typically feature a hinged display screen on the main unit that can be opened and closed relative to the main unit. This allows the display screen to be opened during operation and closed for storage and transport. To further adapt to customer needs, existing electronic devices often employ a dual-axis pivot to achieve a wide rotation angle of 0-360°, facilitating display, viewing, and operation from various angles. However, the trend towards thinner and lighter designs in current electronic devices can impact heat dissipation. When the display screen is opened to 75-135°, the main unit is often placed flat on a table, which can easily lead to lag due to poor heat dissipation, thus affecting the user experience. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned problems of the prior art and provide a linkage-type pivot with a foot pad reciprocating mechanism, suitable for electronic products with large-angle rotation and with efficient heat dissipation.

[0004] The objective of this utility model is mainly achieved through the following technical solutions:

[0005] A linkage-type pivot with a foot pad reciprocating mechanism includes a first shaft, a second shaft, a switching component for controlling the relative rotation of the first shaft and the second shaft, and a torque component for providing rotational interference force to the first shaft and the second shaft, and also includes a reciprocating linkage component;

[0006] The reciprocating linkage assembly includes a linkage support frame sleeved on a second shaft. The linkage support frame is provided with foot pads that can move up and down. A slide rail is connected to the foot pads. A first gear, a second gear, a third gear, and a fourth gear that mesh sequentially are rotatably arranged on the linkage support frame. The first gear is sleeved on the second shaft and can rotate relative to the second shaft. The ring surface of the first gear has an idle section that cannot mesh with the second gear. The end of the fourth gear is connected to a connecting rod. The end of the connecting rod is connected to a slider that can slide with the slide rail.

[0007] When the slider is at the extreme position at both ends of the slide rail, the foot pad is in the high position; when the idle section is directly opposite the second gear, the foot pad is in the low position.

[0008] The reciprocating linkage assembly also includes a drive plate, the top and bottom ends of which are respectively sleeved on the first shaft and the second shaft, and the lower end of the drive plate is connected to the first gear.

[0009] Furthermore, the slide rail is provided with a transversely arranged transverse sliding groove.

[0010] It also includes a transverse screw that passes through the transverse groove from the outside and is threaded to the slider. The transverse screw can slide within the transverse groove.

[0011] Furthermore, the inner end of the slide rail is also provided with a transverse limiting groove that communicates with the transverse sliding groove opening;

[0012] The slider is provided with a lateral limiting protrusion that cooperates with the lateral limiting groove.

[0013] Furthermore, a limiting block is connected to the top of the foot pad, and the slide rail is connected to the limiting block;

[0014] The linkage support frame has several vertically arranged vertical sliding slots, and also includes a vertical screw that passes through the vertical sliding slot from the outside and is threaded to the limiting block. The vertical screw can slide within the vertical sliding slot.

[0015] Furthermore, the outer surface of the limiting block is provided with a plurality of sliding strips that contact the inner surface of the linkage support frame.

[0016] Furthermore, the linkage support frame includes a first linkage support plate and a second linkage support plate spaced apart from the first linkage support plate. The end of the first linkage support plate is bent into a support plate extension section in a direction close to the second linkage support plate, and there is a clearance area between the support plate extension section and the end of the second linkage support plate.

[0017] The limiting block and the slide rail are connected by a connector that passes through the clearance area.

[0018] Furthermore, the vertical sliding grooves are distributed on both the first linkage support plate and the extension of the support plate.

[0019] Furthermore, the bottom end of the drive plate has a drive sleeve section sleeved on the first shaft, and the inner wall surface of the drive sleeve section is provided with an outwardly protruding connecting plane A.

[0020] The end of the first gear is provided with a linkage insertion section that passes through the linkage support frame and inserts into the drive sleeve section. The outer surface of the linkage insertion section is provided with a concave linkage plane B that matches the linkage plane A.

[0022] The second shaft is connected to a second connecting plate that is connected to the linkage support frame, and the second connecting plate has a second connecting hole.

[0023] This invention offers the following advantages: The foot pad reciprocating mechanism designed in this invention is suitable for dual-axis devices with large-angle rotation from 0 to 360°. Specifically, through the cooperation of the drive plate and various gears, in the zero position, the foot pad is retracted to the area near the linkage connecting frame, reaching a high position and being stored inside the host system end, thus reducing the protruding structure of the electronic product and preventing accidental collision and wear. At a specific small angle, the foot pad can extend out of the linkage connecting frame to support the host system end. At a specific large angle, the foot pad is retracted back to the area near the linkage connecting frame to create suitable overlapping space. The cooperation between the horizontal screw and the horizontal sliding groove, as well as the cooperation between the vertical screw and the vertical sliding groove, improves the stability of the foot pad's vertical movement. Therefore, this invention expands the heat dissipation space, effectively improves heat dissipation performance, and thus enhances the user experience, possessing the advantages of ingenious structure, stable operation, and reliability.

[0044] To enable those skilled in the art to better understand this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0045] Example 1

[0046] like Figures 1 to 28 As shown, the linkage pivot with foot reciprocating mechanism includes a first shaft 10, a second shaft 20, a switching component 30 for controlling the relative rotation of the first shaft 10 and the second shaft 20, and a torque component 50 for providing rotational interference force to the first shaft 10 and the second shaft 20, and also includes a reciprocating linkage component 40.

[0047] The reciprocating linkage assembly 40 includes a linkage support frame 41 sleeved on the second shaft 20. A foot pad 46 is movably mounted on the linkage support frame 41. A slide rail 47 is connected to the foot pad 46. A first gear 42, a second gear 43, a third gear 44, and a fourth gear 45 are rotatably mounted on the linkage support frame 41 and mesh sequentially. The first gear 42 is sleeved on the second shaft 20 and can rotate relative to the second shaft 20. The ring surface of the first gear 42 has an idle section 420 that cannot mesh with the second gear 43. The end of the fourth gear 45 is connected to a connecting rod 48. The end of the connecting rod 48 is connected to a slider 49 that can slide with the slide rail 47.

[0048] When the slider 49 is at the extreme position at both ends of the slide rail 47, the foot pad 46 is in a high position; when the idle section 420 is facing the second gear 43, the foot pad 46 is in a low position.

[0049] The reciprocating linkage assembly 40 also includes a drive plate 419, the top and bottom ends of which are respectively sleeved on the first shaft 10 and the second shaft 20, and the lower end of the drive plate 419 is connected to the first gear 42.

[0050] Preferably, the first shaft 10 is connected to a first connecting plate 11, and the first connecting plate 11 has a first connecting hole 12.

[0051] The second shaft 20 is connected to a second connecting plate 21 that is connected to the linkage support frame 41, and the second connecting plate 21 has a second connecting hole 22.

[0052] In application, the first axis 10 is connected to the display screen via the first connecting plate 11, and the second axis 20 is connected to the host system via the second connecting plate 21.

[0053] The switching component 30 is used to control the rotation angle between the first axis 10 and the second axis 20, that is, to control how the display screen end and the host system end achieve a large rotation of 0-360°. The torque component 50 is used to provide interference force for the relative rotation of the first axis 10 and the second axis 20 so as to maintain the angle state. The switching component 30 and the torque component 50 can be referred to in the utility model patent application with application number 202311223264. Since they are not utility model points of this embodiment, they will not be described in detail.

[0054] This embodiment divides the 0-360° rotation into four stages. In the first stage, the first axis 10 remains stationary while the second axis 20 rotates relative to it, resulting in an angle of 0°-75° between the first axis 10 and the second axis 20. In the 0° state, the display screen is upright on top of the host system, and the feet 46 should be in a high position, that is, near the extreme position of the connecting bracket 75. At this time, the feet 46 can be retracted into the host system. In the second stage, the first axis 10 remains stationary while the second axis 20 rotates relative to it, resulting in an angle of 75°-135° between the first and second axes. In this angle state, the host system is usually placed flat on the table, while the display screen is tilted open by 75°. -135° to facilitate operation by users. To improve heat dissipation, the foot pad 46 should be in a low position, that is, it should move away from the linkage bracket 75 and extend from the host system end to support the host system end. In the third stage, the second axis 20 is stationary and the first axis rotates relative to it, so that the angle between the first axis 10 and the second axis 20 is 135°-300°. In the fourth stage, the first axis 10 is stationary and the second axis rotates relative to it, so that the angle between the first axis 10 and the second axis 20 is 300°-360°. In this stage, the display screen end is stacked in reverse on the bottom of the host system end, and the foot pad 46 for heat dissipation should be retracted to the zero position to make way for the display screen end.

[0055] To accommodate the extended position of the foot pad 46 within the 75°-135° range, the central angle corresponding to the idle section 420 should be 30°. Figure 18 and Figure 21 As shown.

[0056] During application, in the first stage (0°-75°), the foot pad 46 is in a high position, such as... Figure 2 and Figure 15 As shown, the first shaft 10, drive plate 419, switching assembly 30, and torque assembly 50 rotate about the second shaft 20 as the rotation axis. During the rotation, as... Figure 15 As shown, the drive plate 419 rotates counterclockwise relative to the second shaft 20. Through the linkage between the drive plate 419 and the first gear 42, the first gear 42 rotates counterclockwise. Sequentially, the second gear 43 rotates clockwise, the third gear 44 rotates counterclockwise, and the fourth gear 45 rotates clockwise. Through the linkage 48, the slider 49 gradually rotates from a high position to a low position. Figure 2 and Figure 17 As shown, at the same time, the slider 49 will slide laterally relative to the slide rail 47, and will drive the slide rail 47 from a high position to a low position. Due to the connection between the slide rail 47 and the foot pad 46, the foot pad 46 will then move to the low position and extend from the linkage support frame 41 to the top of the main unit system end, as shown. Figure 17 As shown; in the second stage (75°-135°), the first shaft 10, drive plate 419, switching assembly 30, and torque assembly 50 are continuously rotated around the second shaft 20 as the rotation axis. Since the idle section 420 is directly opposite the second gear 43 in this stage, as... Figure 18 As shown, even though the first gear 42 rotates with the drive plate 419, the second gear 43, the third gear 44, and the fourth gear 45 remain stationary due to the loss of engagement. Similarly, the foot pad 46 remains extended. Figure 20 As shown, in this state, there is sufficient gap between the host system and the desktop to expand the heat dissipation space and effectively improve heat dissipation performance; in the third stage (135°-300°), the second axis 20, drive board 419, switching component 30, and torque component 50 are kept stationary, and the first axis 10 is rotated about its axis of rotation, as shown. Figure 21 As shown, in this state, the drive plate 419 does not rotate, so the first gear 42, the second gear 43, the third gear 44, and the fourth gear 45 are all in a stopped state. Similarly, the foot pad 46 also remains extended. Figure 23 As shown; in the fourth stage (300°-360°), the first shaft 10, drive plate 419, switching assembly 30, and torque assembly 50 are rotated around the second shaft 20 as the rotation axis, as follows. Figure 24As shown, during rotation, the drive plate 419 rotates counterclockwise relative to the second shaft 20. Through the linkage between the drive plate 419 and the first gear 42, the first gear 42 rotates counterclockwise. Sequentially, the second gear 43 rotates clockwise, the third gear 44 rotates counterclockwise, and the fourth gear 45 rotates clockwise. Through the linkage 48, the slider 49 gradually rotates from a low position to a high position. Simultaneously, the slider 49 slides laterally relative to the slide rail 47, causing the slide rail 47 to move from a low position to a high position. Due to the connection between the slide rail 47 and the foot pad 46, the foot pad 46 moves to a high position and retracts, returning to its retracted state. Figure 28 As shown, this allows the display screen to be stacked in reverse on the bottom of the host system.

[0057] Specifically, when the slider 49 is at the extreme position at both ends of the slide rail 47, the foot pad 46 is in a high position, which means that the foot pad 46 moves upward (retracts) to its extreme position; when the idle section 420 is facing the second gear 43, the foot pad 46 is in a low position, which means that the foot pad 46 moves downward (extends) to its extreme position.

[0058] Among them, such as Figure 8 As shown, in order to achieve sliding cooperation between slider 49 and slide rail 47, slider 49 is provided with sliding notch 427 that cooperates with slide rail 47.

[0059] Among them, such as Figure 6 As shown, in order to achieve the linkage connection between the connecting rod 48 and the end of the fourth gear 45, a central shaft rod 429 that is linked to the fourth gear 45 can be provided through the central shaft portion of the fourth gear 45. The central shaft rod 429 is rotatably mounted on the linkage support frame 41, and the connecting rod 48 is connected to the end of the central shaft rod 429.

[0060] Preferably, the slide rail 47 is provided with a transversely arranged transverse slide groove 428;

[0061] It also includes a transverse screw 410 that passes through the transverse groove 428 from the outside and is threaded to the slider 49. The transverse screw 410 can slide within the transverse groove 428.

[0062] In this embodiment, the horizontal screw 410 improves the stability of the movable connection between the slider 49 and the slide rail 47, preventing them from disengaging and causing operational failure. Furthermore, the cooperation between the horizontal screw 410 and the horizontal slide groove 428 enhances the stability of the slider 49's lateral sliding.

[0063] Preferably, the inner end of the slide rail 47 is further provided with a transverse limiting groove 425 that communicates with the transverse sliding groove opening 428;

[0064] The slider 49 is provided with a lateral limiting protrusion 426 that cooperates with the lateral limiting groove 425.

[0065] In this embodiment, the stability of the slider 49 sliding laterally can be further improved by the cooperation of the lateral limiting groove 425 and the lateral limiting protrusion 426.

[0066] Preferably, the top of the foot pad 46 is connected to a limiting block 411, and the slide rail 47 is connected to the limiting block 411;

[0067] The linkage support frame 41 has several vertically arranged vertical sliding slots 412, and also includes a vertical screw 413 that passes through the vertical sliding slots 412 from the outside and is threadedly connected to the limiting block 411. The vertical screw 413 can slide within the vertical sliding slots 412.

[0068] In this embodiment, the vertical screw 413 improves the stability of the movable connection between the foot pad 46 and the linkage support frame 41. Furthermore, the cooperation between the vertical screw 413 and the vertical sliding groove 412 further enhances the stability of the foot pad 46's vertical movement.

[0069] Preferably, the outer surface of the limiting block 411 is provided with a plurality of sliding strips 414 that contact the inner surface of the linkage support frame 41.

[0070] In this embodiment, the sliding bar 414 reduces the friction between the limiting block 411 and the linkage support frame 41, thereby improving the sensitivity of the foot pad 46 in moving up and down. The outer surface of the sliding bar 414 is curved.

[0071] Preferably, the linkage support frame 41 includes a first linkage support plate 415 and a second linkage support plate 416 spaced apart from the first linkage support plate 415. The end of the first linkage support plate 415 is bent towards the second linkage support plate 416 to form a support plate extension section 417. There is a clearance area between the support plate extension section 417 and the end of the second linkage support plate 416.

[0072] The limiting block 411 and the slide rail 47 are connected by a connector 418 that passes through the clearance area.

[0073] In this embodiment, the two ends of the first gear 42, the second gear 43, the third gear 44, and the fourth gear 45 are rotatably connected to the first linkage support plate 415 and the second linkage support plate 416, respectively. The slider 414 may also be provided on the connecting member 418.

[0074] Preferably, the vertical sliding grooves 412 are distributed on both the first linkage support plate 415 and the support plate extension 417.

[0075] In this embodiment, the support plate extension 417 and the first linkage support plate 415 can limit the two end faces of the limiting block 411, thereby further improving the stability of the limiting block 411 moving up and down.

[0076] To enable the drive plate 419 to drive the first gear 42, preferably, the bottom end of the drive plate 419 has a drive sleeve section 421 sleeved on the first shaft 10, and the inner wall surface of the drive sleeve section 421 is provided with an outwardly protruding drive plane A422.

[0077] The end of the first gear 42 is provided with a linkage insertion section 423 that passes through the linkage support frame 41 and inserts into the drive sleeve section 421. The outer surface of the linkage insertion section 423 is provided with a concave linkage plane B424 that matches the linkage plane A422.

[0078] In this embodiment, as Figure 14 As shown, both sides of the inner wall of the drive sleeve section 421 can be provided with a linkage plane A422, correspondingly, as... Figure 13 As shown, linkage planes B424 are provided on both sides of the linkage insertion section 423.

[0079] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific embodiments of the present invention are limited to these descriptions.
