Description

Technical Field

[0001] This application relates to the field of folding table technology, and more particularly to a folding table structure. Background Technology

[0002] Folding structures have wide applications in furniture products, especially in scenarios where space utilization is crucial. Folding tables are increasingly being adopted due to their ease of storage and quick unfolding. Existing folding tables often incorporate rotatable support mechanisms and drive components, allowing the tabletop to switch between folded and unfolded states to adapt to different usage needs.

[0003] In some existing designs, the coordination between the support mechanism and the drive components may affect the overall unfolding effect and load-bearing capacity. Therefore, how to optimize the existing structural layout to improve the reliability and practicality of the folding structure remains a technical problem that continues to be explored in this field. Based on this, this application proposes a folding table structure. Utility Model Content

The first end of the push rod assembly is rotatably connected to a first connection point on the support frame, and the second end is rotatably connected to a second connection point on the mounting bracket. One end of the support frame is rotatably connected to the mounting bracket via a third connection point. The push rod assembly is used to drive the support frame to fold or unfold relative to the mounting bracket. The support frame is provided with a support plane for fixing a desktop panel. When the support frame is in the fully unfolded position, the angle between the line connecting the first connection point and the second connection point and the support plane is greater than 45 degrees.

The end of the push rod is rotatably connected to the first connection point, and the end of the guide sleeve is connected to the second connection point. When the support frame is in the fully extended position, the angle between the push rod and the support plane is greater than 45 degrees.

[0008] Optionally, the support frame includes a longitudinal support member and a connector, the connector being located in the middle of the longitudinal support member, and one end of the push rod assembly being rotatably connected to a first connection point on the connector.

[0009] Optionally, the connector is located on the longitudinal support at one-third of the distance from the third connection point.

[0010] Optionally, the longitudinal support member includes longitudinal support rods respectively disposed on the left and right sides, and the connector includes a transverse connecting rod connecting the longitudinal support rods on the left and right sides.

[0011] Optionally, the transverse connecting rod is an L-shaped rod, with the first connection point located on one surface of the L-shaped rod and a notch on the other surface, the position of which is aligned with the position of the push rod.

[0012] Optionally, the support member further includes a transverse support member, which is fixedly connected to the longitudinal support member.

[0018] The folding table structure provided by this invention, by setting a push rod assembly between the support frame and the mounting bracket, and rationally arranging the angle relationship between the push rod assembly and the support plane, makes the force transmission of the support frame in the fully unfolded state more effective, which helps to improve the overall stability and load-bearing capacity of the tabletop during use. The push rod assembly has good directional matching of driving force during operation, which helps to improve the smoothness and durability of the structure's operation and reduces the risk of swaying or local loosening caused by biased force. Furthermore, the overall structure is compact and suitable for integration into various types of folding table products, possessing good adaptability and versatility. Attached Figure Description

[0029] See Figures 1 to 5 :

[0030] This application provides an embodiment of a folding table structure, including:

[0031] The support frame 01, push rod assembly 02, and mounting bracket 03 are provided. The push rod assembly 02 has a first end 04 and a second end 05. The first end 04 of the push rod assembly 02 is rotatably connected to a first connection point 06 on the support frame 01, and the second end 05 is rotatably connected to a second connection point 07 on the mounting bracket 03. One end of the support frame 01 is rotatably connected to the mounting bracket 03 through a third connection point 08. The push rod assembly 02 is used to drive the support frame 01 to fold or unfold relative to the mounting bracket 03. The support frame 01 is provided with a support plane 09, which is used to fix the desktop panel. When the support frame 01 is in the fully unfolded position, the angle between the line connecting the first connection point 06 and the second connection point 07 and the support plane 09 is greater than 45 degrees.

[0032] This embodiment provides a folding table structure, including a support frame 01, a push rod assembly 02, and a mounting bracket 03.

[0033] The push rod assembly 02 has a first end 04 and a second end 05. The first end 04 is rotatably connected to a first connection point 06 on the support frame 01, and the second end 05 is rotatably connected to a second connection point 07 on the mounting bracket 03. One end of the support frame 01 is rotatably connected to the mounting bracket 03 via a third connection point 08. The arrangement of these three points allows the push rod assembly 02 to drive the support frame 01 to rotate relative to the mounting bracket 03 around the third connection point 08 during extension and retraction, thereby achieving folding or unfolding.

[0034] A support plane 09 is provided on the support frame 01 for installing and fixing the desktop panel. After the structure is unfolded, the support plane 09 is used to bear the load and maintain a stable horizontal state.

[0035] In this embodiment, when the support frame 01 is in the fully extended position, the angle formed between the line connecting the first connection point 06 and the second connection point 07 and the support plane 09 is greater than 45 degrees. For example... Figure 3In the diagram, the longer dashed line represents the line connecting the two connection points, and the shorter dashed line represents the projection of that line onto the supporting plane. The angle θ formed by the two dashed lines is greater than or equal to 45 degrees. This angle setting allows the push rod assembly 02 to provide stronger support to the support frame 01 in the deployed state, while also forming a better mechanical support path, improving the overall structural stability and load-bearing capacity. Especially during heavy loads or long-term use, this angle design helps reduce the risk of component deformation and stress concentration at connection points.

[0036] In practice, the included angle can be reasonably designed according to the desktop size, expected load-bearing requirements and installation space. The common range is between 50 degrees and 70 degrees, so as to balance mechanical performance and structural compactness.

[0037] In this embodiment, due to the specific angle setting of the connection structure between the push rod assembly and the support frame, especially the relative positional relationship between the first connection point and the second connection point, it is possible to effectively prevent the push rod from entering a "dead point" position during the folding process (i.e., the push rod and the support component form an approximately straight line, resulting in reduced torque transmission efficiency or even failure). With the reasonable push rod length and connection angle, the push rod is always in a state of force with a lever arm when the support frame is folding, which can continuously and smoothly drive the support frame to complete the folding process.

[0038] This structural arrangement not only improves the controllability of the folding action, but also significantly reduces the "bouncing" phenomenon of the support frame caused by the sudden loss of support force after the push rod enters the dead point. It helps to avoid potential safety risks caused by violent shaking of the equipment structure or user misoperation, thereby enhancing the stability and safety of the overall structure in the folded state.

[0039] It should be noted that the push rod assembly 02 can be a mechanical telescopic rod, a gas spring structure, or may include an electric drive component. The specific implementation can be flexibly adjusted according to the usage scenario. Replacing the shape, driving method, and material of the connector 13 without changing the basic connection relationship is also within the scope of protection of this invention.

[0040] In this embodiment, the "fully extended position" refers to the state of the support frame 01 when it is rotated and extended relative to the mounting bracket 03 to a predetermined limit position. At this time, the support frame 01 forms a stable planar structure for supporting the desktop panel, the push rod assembly 02 is in a stretched or near-maximum elongated state, and provides vertical or near-vertical support force to the support frame 01. This position is typically the final position in the use state, that is, the support frame 01 is in the arrangement where the force is most stable and the overall structure is closest to a rigid state.

[0041] It should be noted that the "fully extended position" is not limited to the push rod assembly 02 being at its absolute extension end or the angle between the support frame 01 and the mounting bracket 03 reaching a certain fixed value. Its specific angle and position can be adapted and adjusted according to different folding table designs, usage scenarios, or the stroke of the push rod 10. For example, in some compact designs, to avoid spatial interference or to achieve tabletop leveling, the fully extended position can be slightly deviated from the conventional vertical support line.

[0042] Therefore, the description of "fully deployed position" in this article should be understood as the maximum deployment or main usage state in a relative sense, and does not constitute the sole limitation on its angle, stroke, or specific structural form. In this position, the angle formed between the push rod assembly 02 and the support plane 09 is greater than 45 degrees. The purpose is to ensure that the push rod 10 provides effective support in the mechanical path, thereby enhancing structural stability.

[0043] The above description is merely one embodiment of the present invention, used to illustrate the structural features and working method of the present invention. Those skilled in the art can make equivalent adjustments and modifications based on this, all of which should fall within the protection scope of the present invention.

[0044] In an optional embodiment, the push rod assembly 02 includes a push rod 10 and a guide sleeve 11. The push rod 10 is telescopically movable in the guide sleeve 11. The end of the push rod 10 is rotatably connected to the first connection point 06, and the end of the guide sleeve 11 is connected to the second connection point 07. When the support frame 01 is in the fully extended position, the angle between the push rod 10 and the support plane 09 is greater than 45 degrees.

[0045] In an optional embodiment, the push rod assembly 02 includes a push rod 10 and a guide sleeve 11, wherein the push rod 10 is slidably disposed relative to the guide sleeve 11 to achieve telescopic cooperation in the length direction. Preferably, the push rod 10 reciprocates telescopically within or outside the guide sleeve 11 along its axial direction, thereby enabling the push rod assembly 02 to adapt to the movement path of the support frame 01 during folding or unfolding.

[0046] The end of the push rod 10 furthest from the guide sleeve 11 is rotatably connected to the first connection point 06 on the support frame 01, while the other end of the guide sleeve 11 is rotatably connected to the second connection point 07 on the mounting bracket 03. Through this structural design, when the push rod assembly 02 drives the support frame 01 to unfold, the push rod 10 gradually extends out of the guide sleeve 11, causing the support frame 01 to rotate and unfold relative to the mounting bracket 03 around the third connection point 08; during the folding operation, the push rod 10 retracts into the guide sleeve 11, thereby causing the support frame 01 to rotate back to the folded state.

[0047] It should be noted that when the support frame 01 is in the fully extended position, the push rod 10 forms an angle with the support plane 09, which is greater than 45 degrees. This design allows the push rod 10 to form a strong axial force distribution in the supported state, which helps to improve the overall stability of the desktop under load and reduce the risk of structural deformation.

[0048] In this embodiment, a guide sleeve 11 is used in conjunction with a push rod 10. Compared with a push rod assembly 02 of fixed length, it has a stronger structural adaptability, can provide a larger support stroke while maintaining a compact layout, and takes into account both mechanical performance and space utilization efficiency. It is suitable for the structural needs of folding tables in different specifications or usage scenarios.

[0049] It should be noted that, in this optional embodiment, one end of the push rod 10 is rotatably connected to the support frame 01 via the first connection point 06, and the other end is connected to the second connection point 07 of the mounting bracket 03 via the guide sleeve 11. Therefore, the central axis of the push rod 10 can be considered as an actual component or specific member of the line connecting the first connection point 06 and the second connection point 07. When the support frame 01 is in the fully extended position, the body of the push rod 10 constitutes the force transmission path between the first connection point 06 and the second connection point 07. At this time, the angle between the push rod 10 and the supporting plane 09 can be considered as a specific manifestation of the angle between the line connecting the connection points and the supporting plane 09. Therefore, in this embodiment, the setting that the angle between the push rod 10 and the supporting plane 09 is greater than 45 degrees is consistent with the angle relationship of the line connecting the connection points described in the claims, and has relevance and functional equivalence.

[0050] This structural arrangement ensures that the push rod 10 has a reasonable force angle when it is unfolded, while also further optimizing the structural stability and spatial arrangement, which is beneficial to the load-bearing performance and safety of the desktop structure in the working state.

[0051] In an optional embodiment, the support frame 01 includes a longitudinal support member 12 and a connector 13, the connector 13 being located in the middle of the longitudinal support member 12, and one end of the push rod assembly 02 being rotatably connected to a first connection point 06 on the connector 13.

[0052] In an optional embodiment, the support frame 01 includes a longitudinal support member 12 and a connector 13. The longitudinal support member 12 supports and fixes the tabletop panel, forming the main load-bearing component of the folding table structure. The connector 13 is located in the middle region of the longitudinal support member 12, serving as an intermediary connecting the push rod assembly 02 and the support frame 01. One end of the push rod assembly 02 is rotatably connected to the connector 13 through a first connection point 06, thereby allowing for angle adjustment relative to the support frame 01 during folding or unfolding.

[0053] By placing the first connection point 06 on the connector 13, rather than directly on both ends of the longitudinal support 12, the push rod assembly 02 can achieve a more reasonable structural layout. On the one hand, this helps optimize the direction of thrust transmission and avoids excessive offset torque during folding and unfolding; on the other hand, it helps maintain an ideal angle (e.g., greater than 45 degrees) between the line formed by the push rod assembly 02 and the support plane 09 after the support frame 01 is unfolded, thereby improving the unfolding stability and load-bearing stiffness of the structure.

[0054] In addition, this design facilitates modular adaptation of support frames 01 of different sizes or structural forms. Without significantly altering the main load-bearing components, the range and angle of the push rod 10 can be flexibly adjusted by adjusting the position of the connector 13, providing good structural compatibility and design freedom.

[0055] Specifically, the connector 13 is located on the longitudinal support 12 at one-third of the distance from the third connection point 08.

[0056] In an optional embodiment, the support frame 01 includes a longitudinal support member 12 and a connector 13. The longitudinal support member 12 serves as a load-bearing skeleton for the desktop panel, and one end of it is rotatably connected to the mounting bracket 03 via a third connection point 08. The connector 13 is fixedly disposed on the longitudinal support member 12. Specifically, the connector 13 is located approximately one-third of the distance from the third connection point 08 along the length of the longitudinal support member 12.

[0057] One end of the push rod assembly 02 is rotatably connected to the connector 13 via the first connection point 06, and the other end is connected to the mounting bracket 03 via the second connection point 07, so that when the push rod assembly 02 extends, retracts or rotates, it can drive the support frame 01 to fold or unfold around the third connection point 08.

[0058] Since the connector 13 is located approximately one-third of the distance from the third connection point 08, the force application point of the push rod assembly 02 is closer to the center than the overall center of gravity of the support frame 01, which helps to optimize the torque transmission path and reduce the off-center load effect during the driving process. At the same time, when the support frame 01 is in the fully deployed position, the push rod assembly 02 can form an angle greater than 45 degrees with the support plane 09, which is beneficial to enhancing the stability and deformation resistance of the structure in the deployed state.

[0059] In addition, this arrangement also provides room for adjustment in structural design. By appropriately adjusting the installation position of the connector 13 on the longitudinal support 12, the thrust direction, folding angle and drive stroke can be optimized according to different desktop sizes, weights or usage scenarios, which has high adaptability and practical value.

[0060] More specifically, the longitudinal support member 12 includes longitudinal support rods 14 respectively disposed on the left and right sides, and the connector 13 includes a transverse connecting rod 15 connecting the longitudinal support rods 14 on the left and right sides.

[0061] Furthermore, in a preferred embodiment, the longitudinal support member 12 includes longitudinal support rods 14 respectively disposed on the left and right sides, with the two longitudinal support rods 14 arranged opposite to each other to provide structural support for the desktop panel along its length. The connector 13 includes a transverse connecting rod 15, which connects the longitudinal support rods 14 on the left and right sides to form a transverse structural connecting unit.

[0062] The first end 04 of the push rod assembly 02 is rotatably connected to the first connection point 06 on the transverse connecting rod 15, and the second end 05 is rotatably connected to the second connection point 07 on the mounting bracket 03. When the push rod assembly 02 is activated, its first end 04 transmits torque through the transverse connecting rod 15, enabling the longitudinal support rods 14 on the left and right sides to fold or unfold synchronously around the third connection point 08.

[0063] Since the transverse connecting rod 15 is located between the two longitudinal support rods 14 and at one-third of the middle of the overall support frame 01, close to the third connection point 08, the driving force of the push rod assembly 02 can be evenly transmitted to the entire support frame 01 structure in the horizontal direction, thereby effectively reducing the twisting or deflection of the structure during the unfolding process and further improving the stability and balance of the structure in the unfolded state.

[0064] In an optional embodiment, the transverse connecting rod 15 is an L-shaped rod, the first connection point 06 is provided on one surface of the L-shaped rod, and a notch 16 is provided on the other surface, the position of the notch 16 being aligned with the position of the push rod 10.

[0065] In an optional embodiment, the transverse connecting rod 15 is an L-shaped rod with two mutually perpendicular rod surfaces. This L-shaped rod is transversely connected between the longitudinal support rods 14 on the left and right sides and serves as the force-bearing connecting member 13 of the push rod assembly 02.

[0066] Specifically, the first connection point 06 is located on one surface of the L-shaped rod and is rotatably connected to the first end 04 of the push rod assembly 02, so that the support frame 01 can be driven to fold or unfold around the third connection point 08 when the push rod assembly 02 extends or retracts. A notch 16 is provided on the other surface, the position of which corresponds to the movement path of the push rod assembly 02 during the folding or unfolding process, thereby reserving movement space for the push rod assembly 02 during structural operation.

[0067] By setting a notch 16 on the L-shaped member, interference between the push rod 10 and the connector 13 during movement can be avoided, improving the flexibility and smoothness of the structural fit. At the same time, the L-shaped structure itself has a certain structural strength, which can stably support and transmit the force applied by the push rod 10, helping to ensure the controllability and reliability of the folding and unfolding actions.

[0068] In an optional embodiment, the support further includes a transverse support 17, which is fixedly connected to the longitudinal support 12.

[0069] In this embodiment, the support also includes a transverse support 17. The transverse support 17 is fixedly connected to the longitudinal support 12 to form a more stable and robust support structure. The transverse support 17 is located in the transverse position of the longitudinal support 12, which enhances the overall structural stability of the support frame 01, allowing the support to distribute the force evenly and preventing excessive deformation or displacement of the structure due to gravity or external forces.

[0070] The horizontal support member 17 can be fixed by bolts, welding, or slot connection, and the specific connection method can be flexibly selected according to actual needs and structural design requirements. The fixed connection design ensures that the horizontal support member 17 and the longitudinal support member 12 form a strong connection unit, which improves the deformation resistance and load-bearing capacity of the support frame 01 during use.

[0071] In addition, the addition of the transverse support 17 gives the support frame 01 better resistance to lateral forces and torsion. Especially when the support frame 01 is subjected to external impact or load changes, the transverse support 17 can effectively resist lateral or torsional moments, ensuring that the support frame 01 can maintain a stable state in different usage environments and extending its service life.

[0072] In an optional embodiment, the mounting bracket 03 includes a back plate 18 and a wing plate 19, the wing plate 19 being disposed on the left and right sides of the back plate 18, the second connection point 07 being located at the bottom end of the back plate 18, and the third connection point 08 being disposed at the top end of the wing plate 19.

[0073] In this embodiment, the mounting bracket 03 includes a back plate 18 and wing plates 19. The back plate 18 and wing plates 19 together constitute the main structural unit of the bracket, providing the necessary stability and strength for the support frame 01. Specifically, the back plate 18 is set as a support surface perpendicular to the ground, used to support and fix other structural components; while the wing plates 19 are respectively set on the left and right sides of the back plate 18, forming the two side support surfaces of the bracket, enhancing the stability of the overall structure.

[0074] The second connection point 07 is located at the bottom end of the back plate 18. The position of the second connection point 07 allows the force of the push rod assembly 02 to be transmitted to the bottom of the mounting bracket 03, thereby effectively supporting and controlling the folding or unfolding action of the support frame 01. By setting the second connection point 07 at the bottom end of the back plate 18, the appropriate force direction can be maintained when the support frame 01 is folded or unfolded, reducing force offset and improving the stability and operability of the structure.

[0075] Furthermore, the third connection point 08 is located at the top of the wing plate 19. The top of the wing plate 19 serves as the other connection point for the push rod assembly 02, effectively transmitting the torque applied by the push rod assembly 02 through the third connection point 08, thus enabling angle adjustment during the folding or unfolding process of the support frame 01. By placing the third connection point 08 at the top of the wing plate 19, not only is the force distribution on the push rod assembly 02 optimized, but it also helps ensure the structural stability and support force of the support frame 01 during unfolding.

[0076] In an optional embodiment, a through hole 20 is provided in the middle of the back plate 18.

[0077] In this embodiment, a through hole 20 is provided in the middle of the back plate 18. The through hole 20 not only helps to reduce the overall weight of the back plate 18, but also optimizes the ventilation and heat dissipation performance of the structure. The position and size of the through hole 20 can be adjusted according to actual needs to ensure that the necessary lightweight design and thermal management functions are provided while ensuring strength and stability.

[0078] The through-hole 20 allows the back plate 18 to effectively distribute stress when bearing pressure, reducing the risk of deformation caused by concentrated pressure. In addition, the through-hole 20 can also provide a passage for installing other components (such as cables, pipes, etc.), increasing the flexibility and adaptability of the design.

[0079] In an optional embodiment, a damping rod 21 is further included, one end of which is rotatably connected to the mounting bracket 03 and the other end of which is rotatably connected to the support frame 01.

[0080] In an optional embodiment, when the support frame 01 is in the fully extended position, the damping rod 21 is in the extended state, and when the support frame 01 is in the fully folded position, the damping rod 21 is in the retracted state.

[0081] In this embodiment, the support frame 01 further includes a damping rod 21. One end of the damping rod 21 is rotatably connected to the mounting bracket 03, and the other end is rotatably connected to the support frame 01. The damping rod 21 is provided to provide a smooth folding and unfolding process, reduce the impact and severe vibration of the support frame 01 during movement, thereby extending the service life of the structure and improving the comfort and safety of operation.

[0082] When the support frame 01 is in the fully extended position, the damping rod 21 is extended. At this time, the damping rod 21 mainly provides appropriate resistance to slowly guide the unfolding process of the support frame 01, preventing structural damage or instability caused by excessively rapid movement due to inertia. Conversely, when the support frame 01 is in the fully folded position, the damping rod 21 is retracted. At this time, the damping rod 21 is in a retracted state, avoiding occupying too much space and not generating resistance to the folding action.

[0083] The advantage of this design is that the damping rod 21 can provide the necessary control force during the unfolding and folding of the support frame 01, ensuring the smooth movement of the support frame 01 and preventing unnecessary wear or damage caused by rapid contraction or unfolding.

[0084] In this application, the push rod 10 can take various forms, such as a single push rod 10 or a double push rod 10. A single push rod 10 can be connected to the support frame 01 and the mounting bracket 03 via a hinged structure, while a double push rod 10 can provide more balanced force transmission, suitable for designs requiring higher stability. The extension and retraction methods of the push rod 10 can include hydraulic, pneumatic, and electric. A hydraulic push rod 10 is suitable for scenarios with large loads and requiring smooth operation; a pneumatic push rod 10 is suitable for applications requiring rapid response; and an electric push rod 10 can achieve precise control and automation through an electronic control system.

[0085] One end of the push rod 10 is typically connected to the support frame 01 via a hinge point, while the other end is connected to the mounting bracket 03 or other components. The connection point can be in the form of a ball joint, universal joint, sliding joint, etc., to ensure that the push rod 10 has sufficient flexibility and stability during operation.

[0086] The damping rod 21 typically consists of an internal hydraulic system, a gas spring, or a friction device, providing controllable damping force. The specific type chosen depends on the desired damping effect. For example, a hydraulic damping rod 21 provides smooth resistance through internal fluid flow, while a gas spring provides resistance through compressed gas, suitable for controlling rapid movements.

[0087] The damping rod 21 can be designed with adjustable damping force, such as a built-in adjustable valve, so that users can adjust the damping strength as needed to provide different damping effects to adapt to different load conditions and usage requirements.

[0088] One end of the damping rod 21 is typically connected to the mounting bracket 03 or support frame 01 via a swivel connection point, and the other end is connected to the support frame 01 via a similar connection method. Ball joints, rolling bearings, hinges, and other connection methods can be selected to ensure that the damping rod 21 has sufficient freedom of movement during operation while avoiding unnecessary wear.
