[0038] In order to make the technical problem solved by the present invention, the technical solution adopted and the technical effect achieved more clearly, the technical solution of the present invention is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0039] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] like Figure 1-Figure 7 As shown, this embodiment provides a table with a flippable tabletop, including a tabletop 1, table legs 2 and a base 3. Two table legs 2 are provided, and the two table legs 2 are relatively arranged below the tabletop 1 for supporting the tabletop 1. The two table legs 2 are both fixed on the base 3.

[0041] The desktop 1 includes a horizontal desktop 12 and a flip desktop 11. The horizontal desktop 12 is provided with a storage space. The flip desktop 11 is arranged in the storage space and can rotate relative to the horizontal desktop 12. The table legs 2 are arranged below the horizontal desktop 12 and the flip desktop 11, and are used to support the horizontal desktop 12 and the flip desktop 11. The storage space is arranged at a position of the horizontal desktop 12 close to the user side to facilitate user operation. The storage space can be set in the middle position, left side or right side of the horizontal desktop 12, and can be set specifically according to user needs. A screen 111 is arranged on one side of the flip desktop 11, and the other side is set as a traditional desktop. The flip desktop 11 can be flipped so that the screen 111 faces the user and is fixed.

[0042] When a user uses a table with a reversible desktop, the user can flip the reversible desktop 11 to the side where the screen 111 faces the user according to different learning scenarios, and touch input can be achieved through the screen 111. Or the reversible desktop 11 can be flipped to the side where the traditional desktop faces the user, and the desktop can meet the user's regular writing or placing of items. Moreover, the reversible desktop 11 can be rotated to any angle and fixed according to comfort requirements.

[0043] The fixing structure of the flip table top 11 after flipping in the prior art is relatively complex, has poor reliability, cannot be fixed at multiple angles, and has poor overall integration with the flip table top.

[0044] In order to solve the above problems, the present embodiment provides a table with a flip table top, in which the flip table top 11 is connected to the outer leg 22 through a damping shaft assembly 6, and the damping shaft assembly 6 includes a shaft 61 and a damping shaft device 62. The shaft 61 is fixed to the flip table top 11 and connected to the outer leg 22 through the damping shaft device 62.

[0045] The damping shaft device 62 includes a fixed plate 621 and a moving plate 622. The fixed plate 621 is arranged on the outer leg 22 and is sleeved on the shaft 61, and is loosely matched with the shaft 61. The moving plate 622 is arranged on the shaft 61 and is in contact with the fixed plate 621 along the axial direction of the shaft 61. The friction between the moving plate 622 and the fixed plate 621 can fix the flip table top 11.

[0046] By applying force to the flip table top 11, the friction between the fixed sheet 621 and the moving sheet 622 can be overcome to allow the flip table top 11 to rotate to any angle. When the external force applied to the flip table top 11 is removed, the friction between the fixed sheet 621 and the moving sheet 622 can fix the flip table top 11, thereby achieving fixation of the flip table top 11 at any angle. The table with a flippable table top can achieve flipping and fixing of the flip table top 11 at any angle, is easy to operate, and has high reliability.

[0047] A lubricant such as vaseline is applied between the contact surfaces of the fixed sheet 621 and the movable sheet 622 to play a lubricating role, thereby preventing the fixed sheet 621 and the movable sheet 622 from being worn due to long-term relative rotation and increasing their service life.

[0048] Furthermore, the damping shaft assembly 6 further includes a butterfly spring piece 63 and a pressing member 64, both of which are arranged along the axial direction of the shaft 61, and the pressing member 64 presses the fixed sheet 621 and the moving sheet 622 through the butterfly spring piece 63. The pressing member 64 presses the butterfly spring piece 63 in the process of rotating with the shaft 61, and the butterfly spring piece 63 is deformed, and its inner ring moves toward the side close to the damping shaft device 62 and abuts against the damping shaft device 62, and the pressing force acting on the moving sheet 622 and the fixed sheet 621 becomes larger and larger, and the friction between the moving sheet 622 and the fixed sheet 621 is larger, so that the reliability of fixing the flip table top 11 is higher.

[0049] Specifically, the rotating shaft 61 includes a first connecting section 611 and a second connecting section 612. The first connecting section 611 is arranged between the flip table 11 and the second connecting section 612. The diameter of the second connecting section 612 is smaller than the diameter of the first connecting section 611. The moving piece 622 is fixed to the second connecting section 612. The fixed piece 621 is arranged between the moving piece 622 and the first connecting section 611. The pressing member 64 is arranged at the second connecting section 612, and the pressing member 64 and the butterfly spring 63 are located on the side of the moving piece 622 away from the fixed piece 621. Such a configuration makes the connection between the first connecting section 611 and the second connecting section 612 a step surface. During the pressing process of the pressing member 64, the fixed piece 621 abuts against the step surface. The pressing member 64 presses the fixed piece 621 and the moving piece 622 between the butterfly spring 63 and the step surface, so that there is always friction between the fixed piece 621 and the moving piece 622, thereby ensuring the reliability of locking the flip table 11.

[0050] A connecting plate 613 is provided at one end of the first connecting section 611 away from the second connecting section 612. The middle part of the connecting plate 613 is fixedly connected to the first connecting section 611. Connecting holes are provided on both sides of the connecting plate 613. Fastening screws pass through the connecting holes to connect to the side of the flip desktop 11.

[0051] Exemplarily, the second connecting section 612 is a flat shaft, and a first fixing groove 6221 is provided at the center of the moving piece 622. The first fixing groove 6221 cooperates with the flat shaft to fix the moving piece 622 to the flat shaft. The flat shaft is formed by milling opposite sides of the shaft, and a first fixing groove 6221 matching the shape of the flat shaft is provided at the center of the moving piece 622 to cooperate with the flat shaft to achieve the fixing of the moving piece 622 to the rotating shaft 61.

[0052] Furthermore, the clamping member 64 is a clamping nut, the arc periphery of the flat shaft is provided with external threads, and the clamping nut is screwed with the external threads. The clamping nut is screwed and fixed with the arc periphery of the flat shaft to achieve the clamping force of the clamping nut on the fixed plate 621 and the moving plate 622.

[0053] Furthermore, the table with a flippable desktop further includes a detection sensor 7, which is disposed in the second connection section 612, on the side of the clamping nut away from the butterfly spring 63, and is used to detect the rotation angle of the rotating shaft 61 and / or the position of the clamping member 64. A second fixing groove 71 is disposed at the center of the detection sensor 7, and the shape of the second fixing groove 71 is also adapted to the shape of the flat shaft, so that the detection sensor 7 is fixed to the rotating shaft 61 and rotates with the rotating shaft 61. The detection sensor 7 can detect the rotation angle of the flip desktop 11, so as to determine whether the flip desktop 11 is rotated to the required position according to the rotation angle of the flip desktop 11, and the required position is that the screen 111 faces the user or the desktop faces the user. At the same time, the side of the detection sensor 7 away from the clamping nut is set to be flush with the end face of the flat shaft, and a light-emitting component is set on the end face of the flat shaft. When the detection sensor 7 is flush with the end face of the flat shaft, the detection sensor 7 cannot sense the light emitted by the light-emitting component. When the detection sensor 7 moves along the axial direction of the rotating shaft 61 and moves away from the first connecting section 611, it means that the clamping nut also moves, which may affect the clamping force on the moving piece 622 and the fixed piece 621, thereby reducing the friction between the moving piece 622 and the fixed piece 621, affecting the fixation of the flip table 11. At this time, the detection sensor 7 can detect the light emitted by the light-emitting component.

[0054] The table with a flip-top provided in this embodiment also includes a central control console 9. The detection sensor 7 transmits a wireless signal to the host 10 or the central control console 9. The host 10 is electrically connected to the screen 111. The data detected by the detection sensor 7 is displayed through the screen 111 or through the screen on the central control console 9.

[0055] In this embodiment, the detection sensor 7 is an angle position sensor, which can display the angle information of the detected rotating shaft 61 and / or the position information of the clamping nut through the screen 111. The angle position sensor sends the detection data to the host 10 in a wireless manner, and the host 10 controls the screen 111 to display the detection data in real time. When the detection sensor 7 detects the light emitted by the light-emitting element, it sends a signal to the host 10, and the host 10 controls the screen 111 to display that the position of the detection sensor 7 has exceeded the set position (the side of the detection sensor 7 away from the clamping nut is flush with the end face of the flat shaft), and maintenance is required. After seeing this, the user can contact the maintenance personnel for maintenance to ensure the reliability of the fixation of the flip table 11.

[0056] The electrical connection method and working principle between the host 10, the detection sensor 7 and the screen 111 are already existing technologies and will not be described in detail here.

[0057] Furthermore, a moving piece 622 and a butterfly spring piece 63 are provided on both sides of the fixing piece 621. By providing the moving piece 622 and the butterfly spring piece 63 on both sides of the fixing piece 621, the friction between the moving piece 622 and the fixing piece 621 is further ensured, thereby improving the reliability of fixing the flip table top 11. It should be noted that the specific number of the moving piece 622 and the butterfly spring piece 63 is not specifically limited in this embodiment, and those skilled in the art can set it according to actual conditions.

[0058] A gasket 65 is provided between the butterfly spring piece 63 near the pressing piece 64 and the pressing piece 64 to prevent loosening. A plastic bearing 66 is provided between the butterfly spring piece 63 near the flip table top 11 and the flip table top 11 to prevent the outer leg 22 from colliding with the flip table top 11 and generating abnormal noise.

[0059] In order to ensure the aesthetics of the table with a reversible tabletop, the table legs 2 are connected to the horizontal tabletop 12 through a connecting frame, and the reversible tabletop 11 is connected to the table legs 2 through a damping shaft assembly 6. Avoidance openings are provided on opposite sides of the accommodation space of the horizontal tabletop 12, and the table legs 2 are connected to the reversible tabletop 11 through the avoidance openings.

[0060] Specifically, a through hole is provided on the side wall of the table leg 2 near the flip table top 11, the shaft 61 passes through the through hole and is matched with the gap of the through hole, the damping shaft assembly 62 is provided in the cavity of the table leg 2, and the end of the fixing plate 621 away from the shaft 61 is fixedly connected to the inner wall of the table leg 2. By providing the damping shaft assembly 6 in the cavity of the table leg 2, the damping shaft assembly 6 is prevented from leaking out, which not only protects the damping shaft assembly 6, but also improves the aesthetics.

[0061] like Figure 5-Figure 8 As shown, the table leg 2 includes an inner leg 21 and an outer leg 22. The inner leg 21 is connected to the base 3, and the outer leg 22 is sleeved on the outer side of the inner leg 21 and connected to the table top 1. A crossbeam 4 is arranged between the two outer legs 22, and a lifting drive mechanism 5 is arranged in the crossbeam 4. The two outer legs 22 are both connected to the lifting drive mechanism 5. The lifting drive mechanism 5 can simultaneously drive the two outer legs 22 to extend and retract relative to the inner leg 21 to drive the table top 1 to rise and fall. The table top 1 is automatically lifted and lowered by the lifting drive mechanism 5 to meet the usage needs of users of different heights.

[0062] Specifically, the lifting drive mechanism 5 includes a motor 51, a worm gear reducer 52 and a lifter 53. The motor 51 is connected to the worm gear reducer 52. Two lifters 53 are provided. Both lifters 53 are connected to the worm gear reducer 52. The lifters 53 are connected to the outer legs 22. The motor 51 can simultaneously drive the two lifters 53 through the worm gear reducer 52 to respectively lift the two outer legs 22. By driving the two lifters 53 to lift and lower simultaneously with one motor 51, the two outer legs 22 can be lifted and lowered at the same time, thereby ensuring the horizontality of the desktop 1 when it is lifted and lowered.

[0063] Of course, in other embodiments, the lifting drive mechanism 5 may not include the motor 51, and the two lifters 53 are driven by the rotating shaft and the connecting assembly, and the rotating shaft is manually rotated to achieve simultaneous lifting of the two outer legs 22.

[0064] Further, the worm gear reducer 52 includes a turbine 521 and a special-shaped connecting rod 522. The main shaft of the motor 51 is connected to the turbine 521, and the turbine 521 is meshed with the special-shaped connecting rod 522 for transmission. Both ends of the special-shaped connecting rod 522 are provided with a first tooth structure 5221. The lifter 53 includes a seat body 531, a screw rod 532 and a connecting seat 533. The seat body 531 is connected to the outer leg 22. One end of the screw rod 532 is rotatably arranged in the seat body 531, and the other end is screwed with the connecting seat 533. The end surface of one end of the screw rod 532 located in the seat body 531 is provided with a second tooth structure 5321. The special-shaped connecting rod 522 passes through the seat body 531 and is rotatably connected with the seat body 531. The first tooth structure 5221 is located in the seat body 531 and meshes with the second tooth structure 5321 for transmission. The end of the connecting seat 533 away from the screw rod 532 is fixed to the inner leg 21. The motor 51 drives the special-shaped connecting rod 522 to rotate through the turbine 521 , and the special-shaped connecting rod 522 drives the two screw rods 532 to rotate at the same time. The rotation of the screw rod 532 can drive the outer leg 22 to rise and fall through the seat body 531 .

[0065] A limiting cavity is provided in the seat body 531, and the two ends of the special-shaped connecting rod 522 respectively pass through the two outer legs 22, and then pass through the seat body 531 to extend into the limiting cavity, and then the first tooth-shaped structure 5221 is fixed to the special-shaped connecting rod 522. The screw rod 532 also extends into the limiting cavity, and the second tooth-shaped structure 5321 on the end face of the screw rod 532 meshes with the first tooth-shaped structure 5221 for transmission. An internal thread is provided in the connecting seat 533, and the screw rod 532 cooperates with the internal thread. Such a setting can limit the screw rod 532 from moving up and down relative to the seat body 531, and at the same time limit the special-shaped connecting rod 522 from moving left and right relative to the seat body 531. The motor 51 then drives the turbine 521 to rotate, the turbine 521 drives the special-shaped connecting rod 522 to rotate, the rotation of the special-shaped connecting rod 522 can drive the screw 532 to rotate, the rotation of the screw 532 can move up and down relative to the connecting seat 533, the up and down movement of the screw 532 can drive the outer leg 22 to move up and down through the seat body 531, and then the outer leg 22 drives the table top 1 to move up and down.

[0066] The table with a reversible tabletop provided in this embodiment has the wiring harness arranged in the table legs 2 and the crossbeam 4, thereby avoiding damage to the wiring harness caused by the lifting of the table legs 2, and having high safety. During installation, it only needs to be connected to the outside through the connection interface 31, without the need for external wiring, which is convenient for installation and movement, and provides a better user experience.

[0067] like Figure 7-Figure 9 As shown, the host 10 of the screen 111 is arranged in the crossbeam 4, and a connection interface 31 is arranged on the base 3. One end of the wire harness is connected to the connection interface 31, and the other end extends along the inner wall of the inner leg 21 and can pass through the outer leg 22 to connect with the lifting drive mechanism 5 and the host 10. A fixed bracket 23 is arranged at one end of the inner leg 21 away from the base 3. The fixed bracket 23 extends in a direction away from the inner leg 21 to the bottom of the desktop 1 when the outer leg 22 is lowered to the lowest position. The wire harness extends from the connection interface 31 to the fixed bracket 23 to form a fixed wire harness section 24; the wire harness fixed from the fixed bracket 23 passes through the outer leg 22 and extends into the crossbeam 4 to form a movable wire harness section 25, and the lifting drive mechanism 5 and the host 10 are both electrically connected to the movable wire harness section 25.

[0068] The wiring harness is classified by function, so that the wiring harness is highly integrated to simplify the number of connection interfaces 31 and the number of wiring harnesses. In this embodiment, three connection interfaces 31 are provided on the base 3, including a power connection interface, a signal line connection interface, and a network cable connection interface.
