Technical Field
[0001] This utility model relates to the field of electric sofa accessories technology, and in particular to a sliding push-type functional frame. Background Technology
[0002] Sofas are an indispensable piece of furniture in modern homes, providing a comfortable place for rest, relaxation, and entertainment. Whether spending leisure time with family in the living room or relieving work fatigue in the office break room, sofas play an important role. As people's quality of life improves, electric sofas have become popular products in the home furnishing market due to their ease of operation and diverse functions. Among them, the sliding flat-push function frame is the core component that enables electric sofas to extend and adjust angles, and its performance is crucial. Existing sliding flat-push function frames can basically meet daily usage needs, but there are still some shortcomings that need to be improved.
[0003] Existing sliding shelves, widely used in the market, are driven by a motor to move sofa cushions, allowing them to automatically extend. Manually folding shelves are also commonly added to the sides of long sofas for easy placement of items. However, with frequent flipping, the metal connectors and hard plastic edges of these shelves easily rub against the sofa upholstery and wooden frame. Over time, noticeable scratches and wear appear on the sofa upholstery around the shelves, and cracks may even appear at the edges of the wooden frame, severely affecting the product's appearance and lifespan. Furthermore, existing folding mechanisms often use simple hinges and locking clips. With repeated use, the hinge shafts may develop gaps due to metal fatigue, and the locking clips may lose precision, causing the shelves to "self-flip." When users place items such as water cups or electronic devices on the sofa, the accidental flipping of the shelves could cause these items to fall and be damaged, posing a significant safety hazard. Therefore, we propose a sliding shelf to solve these problems. Utility Model Content
[0004] The purpose of this invention is to provide a sliding push-type functional frame to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sliding push-type functional rack, comprising two sets of fixed frames, each set of fixed frames having two sets of linear guide rail frames connected to both sides via a first mounting seat and a second mounting seat, a sleeve rod installed at the middle position of the two sets of linear guide rail frames, the sleeve rod being connected to a sleeve seat via a drive assembly, a push-type rack installed at the top of the sleeve seat, guide rail seats installed on both sides of the push-type rack, the two sets of guide rail seats forming a sliding connection with the two sets of linear guide rail frames, a first rotating seat fixed on each of the two sets of second mounting seats, a first rotating bracket rotatably connected to each of the two sets of first rotating seats, a shelf plate rotatably connected to the end of the first rotating bracket away from the first rotating seat, a second rotating seat fixed to the rear end of each of the two sets of guide rail seats, a second rotating bracket rotatably connected to the second rotating seat, a shelf plate rotatably connected to the end of the second rotating bracket away from the second rotating seat.
[0006] As an improved technical solution, the opposite ends of the two sets of guide rail seats are installed inside the two sets of slide rail balls, and the two sets of guide rail seats and slide rail balls form a sliding connection.
[0007] As an improved technical solution, the drive assembly includes a servo motor installed at the rear end of the sleeve rod, a high-precision ball screw rotatably connected inside the sleeve rod, the rear end of the high-precision ball screw being connected to the output end of the servo motor, a sleeve seat provided outside the sleeve rod, and the sleeve seat being threadedly connected to the high-precision ball screw through a nut coupling.

[0010] As an improved technical solution, multiple sets of slide rail balls are installed at the front end of both sets of linear guide rails.
[0011] As an improved technical solution, limit rings are installed at both ends of the two sets of linear guide rails.
[0012] After adopting the above technical solution, the beneficial effects of this utility model are:
[0013] This invention features rotatable shelving units mounted on guide rails and two sets of second mounting seats on both sides of a push-pull frame. As the push-pull frame moves, it simultaneously unfolds and retracts the two shelving units.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0020] This utility model provides a technical solution as follows: Figures 1 to 4As shown, in this embodiment, a sliding push-type functional frame includes two sets of fixed frames 1. Both sides of the two sets of fixed frames 1 are connected to two sets of linear guide rail frames 4 via a first mounting base 2 and a second mounting base 3. A sleeve rod 5 is installed in the middle of the two sets of linear guide rail frames 4. A servo motor 6 is installed at the rear end of the sleeve rod 5. A high-precision ball screw 9 is rotatably connected inside the sleeve rod 5. The rear end of the high-precision ball screw 9 is connected to the output end of the servo motor 6. A sleeve seat 8 is provided outside the sleeve rod 5. The sleeve seat 8 is threadedly connected to the high-precision ball screw 9 via a nut coupling 10. A flat... The push frame 7 and the flat push frame 7 are both equipped with guide rail seats 11. The two sets of guide rail seats 11 are slidably connected to the two sets of linear guide rail frames 4. The two sets of second mounting seats 3 are each fixed with a first rotating seat 13. The two sets of first rotating seats 13 are each rotatably connected with a first rotating bracket 14. The end of the first rotating bracket 14 away from the first rotating seat 13 is rotatably connected with a shelf plate 15. The rear end of the two sets of guide rail seats 11 is each fixed with a second rotating seat 16. The second rotating seat 16 is rotatably connected with a second rotating bracket 17. The end of the second rotating bracket 17 away from the second rotating seat 16 is rotatably connected with a shelf plate 15.
[0021] By installing rotatable shelving plates 15 on the guide rail seats 11 on both sides of the push frame 7 and on the two sets of second mounting seats 3, the push frame 7 can simultaneously drive the two sets of shelving plates 15 to unfold and retract during movement. This allows the shelving plates 15 to automatically flip the shelves on them. When the shelving plates 15 need to be retracted, they can be flipped to the rear of the equipment, reducing the friction area between the shelves on the shelving plates 15 and the sofa surface. This also effectively prevents the shelves on the shelving plates 15 from "self-flipping," thus preventing items from falling or being damaged due to accidental flipping of the shelves on the shelving plates 15 and improving safety during use.
[0022] In other embodiments, the opposite ends of the two sets of guide rail seats 11 are installed inside the two sets of slide rail balls 12, and the two sets of guide rail seats 11 and slide rail balls 12 form a sliding connection.
[0023] When the pusher 7 drives the two sets of guide rail seats 11 to move laterally along the surface of the linear guide rail frame 4, it can effectively prevent the two sets of guide rail seats 11 from shaking during the movement, thereby effectively improving the stability of the two sets of guide rail seats 11 during movement.
[0024] In other embodiments, the drive assembly includes a servo motor 6 mounted on the rear end of the sleeve 5, a high-precision ball screw 9 rotatably connected inside the sleeve 5, the rear end of the high-precision ball screw 9 being connected to the output end of the servo motor 6, a sleeve seat 8 being provided outside the sleeve 5, and the sleeve seat 8 being threadedly connected to the high-precision ball screw 9 through a nut coupling 10. The input end of the servo motor 6 is electrically connected to an external controller through a wire.
[0025] By installing a movable push frame 7 on the fixed frame 1, the servo motor 6 can drive the high-precision ball screw 9 in the sleeve rod 5 to rotate in both directions, thereby achieving smooth displacement of the push frame 7. Furthermore, by installing flip-up shelf plates 15 on the guide rail seats 11 on both sides of the push frame 7 and on the two sets of second mounting seats 3, the push frame 7 can synchronously drive the two sets of shelf plates 15 to unfold and retract during movement. This allows the external controller to precisely control the operation of the servo motor 6, ensuring that the servo motor 6 can be used normally and enabling the equipment to operate automatically.
[0026] In other embodiments, the shelf panel 15 has multiple sets of mounting grooves;
[0027] This design makes it easy to install the sofa shelf on the shelf plate 15, allowing the shelf plate 15 to automatically rotate the sofa shelf.
[0028] In other embodiments, a travel limiter 18 is installed at the middle of each of the two sets of second mounting bases 3;
[0029] This design allows the travel limiter 18 to limit the rotation angle of the first rotating bracket 14, preventing overtravel damage when the first rotating bracket 14 rotates toward the travel limiter 18.
[0030] In other embodiments, multiple sets of slide rail balls 12 are installed at the front ends of both sets of linear guide rail frames 4;
[0031] With this design, when the guide rail seat 11 slides along the linear guide rail frame 4 to the slide rail ball 12, the smoothness of the sliding of the guide rail seat 11 can be improved and the noise generated when the guide rail seat 11 moves can be reduced.
[0032] In other embodiments, limit rings 19 are installed at both ends of the two sets of linear guide rails 4;
[0033] This design allows the limiting ring 19 on the linear guide rail frame 4 to limit the movement of both sides of the linear guide rail frame 4, preventing the guide rail seat 11 outside the linear guide rail frame 4 from completely detaching from the interior of the linear guide rail frame 4.
[0034] This utility model provides a sliding push-type functional frame, the specific working principle of which is as follows:
[0035] When using this equipment, if it is necessary to retract the shelf on the shelf panel 15 and retract the sofa, the servo motor 6 can be activated. The servo motor 6 drives the high-precision ball screw 9 inside the sleeve rod 5 to rotate, allowing the push frame 7 to move backward under the combined action of the nut coupling 10 and the two sets of guide rail seats 11. This causes the sofa cushion mounted on the push frame 7 to retract. During the movement of the push frame 7, the two sets of guide rail seats 11 push the second rotating seat 16 towards the second mounting seat 3, allowing the shelf panel 15 to flip under the action of the second rotating seat 16. This achieves a smooth transition from the unfolded state to the retracted state of the shelf panel 15, allowing the shelf panel 15 to automatically flip to the rear end of the second mounting seat 3 (e.g., ...). Figure 2 As shown), this eliminates the need for manual rotation of the shelf. When the shelf panel 15 needs to be unfolded, the user sends a reverse command through the controller, causing the servo motor 6 to reverse, and the sleeve 8 to drive the push frame 7 to retract, simultaneously unfolding and resetting the shelf panel 15 (as shown). Figure 1 (As shown), the operation is now complete.
[0036] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.
[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
