Description

[Technical field]

[0001] The utility model relates to the technical field of flip-type lifting, in particular to a synchronous flip-type lifting frame for a hidden lifting coffee table. [Background technology]

[0002] The flipping mechanism of the existing flip lift coffee table mostly adopts a bending processing method to produce a limit baffle on the connecting piece, so that the connecting piece can flip and move, and at the same time limit the flipping position of the table top, so that the table top can be closed into the opening of the table frame. However, due to the poor precision of the bending processing method, the inclination angle and the bending angle of the bent limit baffle are difficult to keep consistent, resulting in unbalanced force on the table top during the flipping process driven by the flipping mechanism, the flipping of the two table tops is not synchronized, and the table top is difficult to accurately correspond to the opening of the table frame, which is easy to cause the table top to get stuck during the flipping process. The problem of the table top scratching the edge of the opening causes the flipping mechanism to operate unsmoothly, be severely worn and make loud noises; moreover, the connection structure between the flipping mechanism and the table top of the existing flip-type lifting coffee table is relatively rigid, and it is difficult for the table top and the flipping mechanism to flip outward flexibly. During the process of flipping and closing the table top, if an object or a hand is clamped, the lifting mechanism can only be controlled by a controller to run in the reverse direction to open the table top, and then the clamped object or hand can be taken out. It is difficult to manually flip the table top outward to take it out. Therefore, the existing lifting coffee table structure lacks a flexible anti-pinch function. [Utility Model Content]

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The utility model is used for a synchronous flip lifting frame of a hidden lifting coffee table, which is provided with a positioning hole and a limiting member.

At the same time, the synchronous flipping of the table board can ensure that the table board accurately corresponds to the opening position of the table frame, so that the table board is accurately closed in the opening of the table frame, avoiding the problem of the table board getting stuck and scratching the edge of the opening during the flipping process, so that the flip mechanism can run smoothly.

[0013] 2. The utility model is used for a synchronous flip lifting frame of a hidden lifting coffee table. When the table board is closed, the screw rod drives the slider to move downward on the slide rail, and the slider pushes the first connecting piece to move downward, the first connecting piece pulls the second connecting piece to move downward, the second connecting piece pulls one end of the third connecting piece to rotate downward, and the other end drives the flip bracket to rotate upward, and at the same time the first tension spring pulls the flip bracket to drive the table board to close toward the center position; since the closing of the table board is mainly achieved by the tension of the first tension spring, the first tension spring is elastic, and the third connecting piece does not have the restriction of flipping downward, the table board can be freely moved outward manually, and in the process of closing the two table boards, if the table board clamps the hand, the table board can be manually flipped outward, the table board is opened and the hand is taken out, and the squeezing force of the hand clamped by the table board is equal to the tension of the first tension spring, which will not cause damage to the hand and has a strong anti-pinching effect.

[Specific implementation method]

[0022] The technical features of the present invention are further described in detail below with reference to the accompanying drawings so that those skilled in the art can understand them.

[0023] A synchronous flip lift frame for a hidden lift coffee table, such as Figure 1 to Figure 7 As shown, it includes a table frame 1 and a table top 2, in which a driving device 4, a lifting mechanism 5 and a flipping mechanism 6 linked to the lifting mechanism 5 are provided in the table frame 1, the table top 2 is provided with two pieces and are engaged with the opening at the upper end of the table frame 1 after being combined, and the flipping mechanism 6 first drives the table top 2 to descend and disengage from the opening at the upper end of the table frame 1 as the lifting mechanism 5 rises, and then synchronously flips outward to open, and the flipping mechanism 6 first drives the table top 2 to synchronously flip inward to the bottom of the opening at the upper end of the table frame 1 and closes as the lifting mechanism 5 descends, and then rises together to the opening at the upper end of the table frame 1 and is flush with the table top, the lifting mechanism 5 is provided with two and is symmetrically installed at the two ends of the table frame 1, the two lifting mechanisms 5 are respectively connected to the two ends of the driving device 4 and operate synchronously under the drive of the driving device 4, and the flipping mechanism 6 is symmetrically arranged on both sides of the lifting mechanism 5 and is respectively fixedly connected to the two table tops 2;

[0024] The flip mechanism 6 includes a first connecting piece 7, a second connecting piece 8, a third connecting piece 9, a flip bracket 10, a first tension spring 11 and a second tension spring 12. The table top 2 is installed and fixed on the flip bracket 10. The two ends of the first connecting piece 7 are respectively hinged to the lower ends of the second connecting pieces 8 on both sides. The upper end of the second connecting piece 8 is hinged to one end of the third connecting piece 9, and the other end of the third connecting piece 9 is hinged to the lower end of the flip bracket 10. The middle section of the third connecting piece 9 is rotatably hinged and installed on the table frame 1. One end of the first tension spring 11 is fixed to the flip bracket 10. The first connecting piece 7 is a first connecting piece 8, and the second connecting piece 8 is a second connecting piece 9. The first connecting piece 7 is a second connecting piece 8, and the second connecting piece 8 is a second connecting piece 9. The second connecting piece 7 is a second connecting piece 8, and the second connecting piece 8 is a second connecting piece 9. The first connecting piece 7 is a second connecting piece 8, and the second connecting piece 8 is a second connecting piece 9. The first connecting piece 7 is a second connecting piece 8, and the second connecting piece 8 is a second connecting piece 8. The first connecting piece 7 is a second connecting piece 8, and the second connecting piece 8 is a second connecting piece 8. The first connecting piece 7 is a second connecting piece 8, and the second connecting piece 8 is a second connecting piece 8. The first connecting piece 8 ...

[0025] During the production and processing of the third connecting piece 9, the positioning hole 13 is positioned and cut by laser with high precision, which can ensure that the corresponding positioning holes 13 and the limiting members 14 in the flipping mechanism 6 are kept in the same height. The sliders 22 on both sides of the table frame 1 are synchronously lifted and lowered under the drive of the driving device 4 and maintain the same height, so that the first connecting piece 7, the second connecting piece 8 and the third connecting piece 9 in the symmetrical flipping mechanism 6 run synchronously. At the same time, the flip bracket 10 drives the table board 2 to flip under the tension of the first tension spring 11. Due to the precise positioning restriction of the limiting member 14, the flip bracket 10 is blocked by the limiting member 14, so that the table board 2 has the same height and the same inclination angle, so that the table boards 2 on both sides flip synchronously. The 2 edges are parallel to each other and maintain the same inclination angle during the flipping process, which solves the deformation problem caused by unbalanced force of the table top 2 due to parts tolerance and inconsistent tension of the first tension spring 11 during the flipping process. At the same time, the synchronous flipping of the table top 2 can ensure that the table top 2 accurately corresponds to the opening position of the table frame 1, so that the table top 2 is accurately closed in the opening of the table frame 1, avoiding the problem of the table top getting stuck and scratching the edge of the opening during the flipping process, so that the flipping process can run smoothly; at the same time, because the closing of the table top 2 mainly relies on the tension of the first tension spring 11, and during the closing and flipping process of the table top 2, there is no restriction on the third connecting piece 9 to flip the table top 2 downward, the table top 2 can be freely moved outward manually to avoid pinching the hands, and it has a flexible anti-pinch function.

[0026] Specifically, Figure 3 to Figure 5 As shown, the limit member 14 is a column extending toward the inner side of the table frame 1 and is perpendicular to the third connecting piece 9, the positioning hole 13 is a through hole or a screw hole, and the limit member 14 is usually set as a rivet or a screw, and the positioning hole 13 and the limit member 14 are located obliquely above the hinge point between the third connecting piece 9 and the flip bracket 10, so that the limit member 14 only limits the height and inclination angle of the upward rotation of the flip bracket 10 when it is closed and flipped, so that the table boards 2 on both sides remain synchronized, and there is no restriction on the downward flipping of the flip bracket 10. When the table boards 2 are closed, only the first tension spring 11 provides the upward flipping pulling force, so that the flip mechanism 6 has a flexible anti-pinch hand function. When the two table boards 2 are closed, if the hand is pinched, the table board 2 can be directly flipped outward manually, and the table board 2 can be opened to take the hand out, which can effectively avoid pinching.

[0027] Specifically, the operation process of the synchronous flip lifting frame is as follows:

[0028] When the controller of the synchronous flip lifting frame controls the table top 2 to flip and open, the driving device 4 runs, the motor assembly 17 drives the transmission rod 18 to rotate, and the transmission rod 18 drives the screw rods 20 at both ends to rotate synchronously through the gear transmission box 19, so that the sliders 22 at both ends of the table frame 1 drive the bracket 23 to move upward synchronously along the slide rail 21. At the same time, the first connecting piece 7 and the second connecting piece 8 move upward under the pull of the second tension spring 12, thereby pushing one end of the third connecting piece 9 to rotate upward. Since the middle section of the third connecting piece 9 can The third connecting piece 9 is hinged on the table frame 1, and the other end of the third connecting piece 9 rotates downward at the same time. At this time, the limiting member 14 pushes the flip bracket 10 to drive the table board 2 to flip downward. When the third connecting piece 9 rotates and hits the lower flip limiting column 16, the flipping process of the table board 2 ends, and the two table boards 2 are fully opened; the slider 22 continues to drive the bracket 23 to move upward along the slide rail 21 until the slider 22 abuts against the bottom end of the upper limit plate 27. At this time, the motor assembly 17 stops running, and the bracket 23 drives the tea tray to rise to the desktop of the tea table;

[0029] When the controller of the synchronous flip lifting frame controls the table top 2 to flip and close, the motor assembly 17 drives the transmission rod 18 to rotate in the opposite direction, and the transmission rod 18 drives the screw rods 20 at both ends to rotate in the opposite direction synchronously through the gear transmission box 19, so that the sliders 22 at both ends of the table frame 1 drive the bracket 23 to move downward synchronously along the slide rail 21. When the bottom end of the slider 22 hits the first connecting piece 7, the clamping plate 24 clamps the first connecting piece 7 to drive the first connecting piece 7 to move downward, and the first connecting piece 7 pulls the second connecting piece 8 to move downward. The connecting piece 8 pulls one end of the third connecting piece 9 to rotate downward, so that the other end of the third connecting piece 9 rotates upward. At the same time, the first tension spring 11 pulls the flip bracket 10 to drive the table top 2 to close and flip toward the center position synchronously under the limit of the limit member 14. Due to the precise positioning limit of the limit member 14, the height and inclination angle of the two table tops 2 are the same. When the flip bracket 10 hits the upper flip limit piece 15, the table top 2 is closed and aligned and completely embedded in the opening on the table frame 1. At this time, the motor assembly 17 stops running, and the table top 2 is flush with the desktop of the coffee table.

[0030] In addition, if Figure 2 or Figure 3As shown, an upper flip limit plate 15 is provided at the upper end of the table frame 1 for supporting the flip bracket 10 when the table board 2 is closed, and a lower flip limit column 16 is provided on both sides of the table frame 1 and above the hinge point between the third connecting piece 9 and the table frame 1 for supporting the third connecting piece 9 when the table board 2 is fully opened. The upper flip limit plate 15 and the lower flip limit column 16 can limit the flip angle range of the flip bracket 10 and the table board 2 to avoid mutual interference between the lifting mechanism 5 and the flip mechanism 6 during operation.

[0031] Specifically, Figure 6 and Figure 7 As shown, a mounting plate 3 is provided at the lower end of the table frame 1, and the driving device 4 is fixedly mounted on the mounting plate 3. The driving device 4 includes a motor assembly 17 and a transmission rod 18 extending to both sides. The lifting mechanism 5 includes a gear transmission box 19 and a screw transmission structure. The gear transmission box 19 is fixedly mounted on both ends of the mounting plate 3 and is respectively connected to both ends of the transmission rod 18. A screw rod 20 extending vertically upward is connected to the gear transmission box 19, and a slide rail 21 is provided outside the screw rod 20. A slider 22 cooperating with the screw rod 20 is slidably provided on the slide rail 21, and a bracket 23 for placing a tea tray is fixedly mounted on the slider 22.

[0032] In addition, if Figure 2 to Figure 5 As shown, the first connecting piece 7 is located below the slider 22 and is perpendicular to the slide rail 21. A clamping plate 24 for clamping the first connecting piece 7 is provided at the bottom end of the slider 22. The clamping plate 24 can maintain stable contact between the slider 22 and the first connecting piece 7. The first connecting piece 7 is attached to the outer side of the slide rail 21. A sliding limit piece 25 is provided on the inner side of the slide rail 21. Sliding limit rods 26 fixedly connected to the first connecting piece 7 are provided at both ends of the sliding limit piece 25. The sliding limit piece 25 and the sliding limit rod 26 can nest and fit the first connecting piece 7 with the slide rail 21, so that the first connecting piece 7 keeps moving in parallel, thereby keeping the second connecting piece 8 and the third connecting piece 9 on both sides of the slide rail 21 in a synchronized state.

[0033] Specifically, an upper limit plate 27 for limiting the rising height of the bracket 23 is provided on the table frame 1 and at the upper end of the slide rail 21. When the slider 22 abuts against the bottom end of the upper limit plate 27, the slider 22 drives the bracket 23 to rise to the set height. At this time, the tea tray on the bracket 23 appears on the desktop of the tea table.

Various modifications and changes can be made without departing from the scope thereof. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field should all fall within the protection scope of the present invention.
