Description

Technical Field

[0001] The present invention relates to the field of workbench control technology, and in particular to a multifunctional control device for an adjustable workbench, and in particular to a multi-mode sliding controller applied to a workbench system with a replaceable auxiliary tabletop. Background Art

[0002] Many workbenches need to be quickly converted between folding, extending and storing to meet different work needs. However, there are few mechanisms on the market that can effectively control such conversion processes, and even if they exist, their implementation methods are often too complicated. This situation highlights the urgent need for a simple and efficient multi-functional control device.

[0003] Some improved designs have appeared in the prior art. For example, CN 114137855 A discloses an intelligent portable trolley-box control console, which realizes multi-functional conversion through a lifting platform and a retractable support rod. Authorization announcement number CN221004437U introduces an industrial robot virtual debugging platform, which improves the flexibility of use through an adjustable display. These designs have improved the adaptability of the workbench to a certain extent, but there are still problems such as complex control mechanism and inconvenient operation.

[0004] At present, the adjustment and control mechanism of the workbench has the following main limitations:

[0005] 1. Insufficient control accuracy: Existing auxiliary table adjustment mechanisms are mostly simple hinge or slide rail structures, which are difficult to achieve precise positioning and stable locking, affecting work accuracy and safety.

[0006] 2. Single function: Most control mechanisms are designed for a single function and cannot simultaneously meet multiple requirements such as sliding, steering and locking, limiting the versatility of the workbench.

[0007] 3. Complex operation: Many adjustable workbenches require complex operating steps or additional tools to complete the adjustment, which reduces the convenience of use.

[0008] 4. Poor adaptability: The existing control mechanism can usually only achieve adjustment in a fixed direction and cannot meet the needs of dynamic changes in the workbench area.

[0009] 5. Low integration: The control mechanism is often added as an independent component, which is not well integrated with the overall structure of the workbench, affecting the aesthetics and space utilization.

[0010] Therefore, developing a multifunctional, high-precision, easy-to-operate control mechanism, such as a multi-mode sliding controller, becomes the key to improving the performance of the workbench. This controller needs to be able to achieve precise positioning, multi-directional adjustment, stable locking, and simple and intuitive operation.

DETAILED DESCRIPTION

[0047] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0048] The embodiments of the present invention are described in detail below in conjunction with all the accompanying drawings. Example

[0049] This embodiment proposes a multi-mode sliding controller 44, which is suitable for a rectangular tabletop workbench, and integrates sliding, steering and locking functions to achieve precise control of the interchangeable auxiliary tabletop 30. The controller is composed of an operating part body 441, a lower fixing member 442, a dual-function spiral actuator 443, and a guide and pivoting matching member 444. Through an innovative design, the interchangeable auxiliary tabletop 30 can be flexibly converted and adjusted between the adjacent two sides of the main tabletop 10.

[0050] The design of the multi-mode sliding controller 44 solves the problems of the traditional workbench adjustment mechanism being complex, low precision, and inconvenient operation. It can not only realize the precise positioning and stable locking of the interchangeable auxiliary table 30, but also support multi-directional adjustment to meet the needs of different work scenes. Through simple operation, the user can easily realize the dynamic adjustment of the workbench area, which greatly improves the flexibility and functional diversity of the workbench.

[0051] For ease of description, we refer to the attached Figure 1An X / Y / Z three-axis coordinate system is established, in which the interchangeable auxiliary table 30 can be flexibly installed on either side of the main table 10 in the X-axis direction or the Y-axis direction. The design of the connection structure 40 embodies a number of innovative functions: it allows the interchangeable auxiliary table 30 to be slidably adjusted on the installation side to adapt to workpieces or operation requirements of different sizes; it has a locking mechanism that can firmly lock the auxiliary table after adjusting to the appropriate position to ensure working stability; it supports the folding and storage function, and the auxiliary table can be folded when it is not needed, saving space and improving the flexibility of the workbench; more innovative is its steering function, which enables the interchangeable auxiliary table 30 to switch between adjacent surfaces, such as from the X-axis direction to the Y-axis direction, or vice versa. This design greatly enhances the adaptability of the workbench and enables it to meet various complex work needs. This multi-functional design significantly improves the practicality and flexibility of the workbench, providing users with a more convenient and efficient working experience.

[0052] The connection structure 40 is the core part of the workbench design. Its composition and function are as follows: First, the right-angle guide rail 41 is formed by seamlessly connecting two mutually perpendicular strip rails. The best solution is to use an integrated molding process. This guide rail is installed on two adjacent edges of the main table 10 to form a precise right angle. The upper surface of the right-angle guide rail 41 is designed with a concave arc surface 411, which extends along the length of the guide rail to form a continuous arc track. Its main function is to provide a sliding and positioning track for the interchangeable auxiliary table 30.

[0053] Secondly, the sliding connector 42 is installed on the lower surface of one side of the interchangeable auxiliary table 30, which is used to carry and support the interchangeable auxiliary table 30, and forms a sliding fit with the right-angle guide rail 41, so that the interchangeable auxiliary table 30 can move smoothly along the guide rail. The sliding connector 42 consists of two main parts: an outer convex arc surface 421 and a connecting plate surface 422. The curvature of the outer convex arc surface 421 matches the inner concave arc surface 411 of the right-angle guide rail 41 to ensure smooth sliding between the two. One end of the connecting plate surface 422 is fixedly connected to the outer convex arc surface 421, and the other end is fixedly connected to the bottom surface of the interchangeable auxiliary table 30, and the thickness of the end connected to the outer convex arc surface 421 is less than the diameter of the outer convex arc surface 421. Usually, two parallel sliding connectors 42 are set, and the spacing between the two is appropriately selected according to the rationality of the support and the size of the interchangeable auxiliary table 30 to ensure stability and load-bearing capacity. You can consider using low-friction materials or roller designs to reduce resistance during movement. In terms of installation configuration, a certain distance is reserved between the convex arc surface 421 and the bottom surface of the interchangeable auxiliary table top 30. This distance serves as an avoidance space when the interchangeable auxiliary table top 30 is flipped and stored. The sliding connection 42 has multiple functional features: the sliding function enables the interchangeable auxiliary table top 30 to slide smoothly on the right-angle guide rail 41 to achieve position adjustment; the flipping function allows the interchangeable auxiliary table top 30 to flip around the axis of the sliding connection 42 for easy storage; within a certain angle range, the contact of the arc surface can also provide a self-locking effect and increase the stability of use. This carefully designed connection structure 40 greatly improves the functionality and practicality of the workbench, enabling it to adapt to various complex work needs.

[0054] In order to further improve the stability of sliding and adjustment, the present invention introduces additional structural designs in certain embodiments. Figure 2 and Fig. 9 The specific improvements are as follows: First, a guiding arc surface 412 is set above the concave arc surface 411, and its cross-section is arc-shaped, partially covering the concave arc surface 411, and its main function is to provide additional guidance and stabilization when the interchangeable auxiliary table 30 moves.

[0055] Secondly, the multi-mode sliding controller 44 is optimized and designed, and its installation position is rearranged so that its guide surface 01 falls exactly on the guide arc surface 412, and the guide surface 01 is designed to match the guide arc surface 412. The working principle of this design is reflected in two aspects: in terms of sliding stability, when the interchangeable auxiliary table 30 moves, the convex arc surface 421 of the sliding connection 42 slides on the concave arc surface 411, and at the same time, the guide surface of the multi-mode sliding controller 44 slides on the guide arc surface 412. This double contact provides better motion stability and accuracy; in terms of position locking mechanism, by operating the multi-mode sliding controller 44, its guide surface 01 presses the guide arc surface 412 downward, and the multi-mode sliding controller 44 cooperates with the two sliding connections 42 to form a three-point locking.

[0056] Third, an adaptive pivot 43 is introduced, which is vertically fixed at the intersection of the right-angle guide rails 41 and is designed to have elastic expansion and contraction capabilities in the vertical direction. A compression spring is integrated inside, for example, the spring constant is 500N / mm, and the maximum compression is 10mm. This design can provide the necessary buffering and adaptive capabilities when the interchangeable auxiliary table 30 turns. The main body of the adaptive pivot 43 is made of high-strength materials, such as heat-treated alloy steel or titanium alloy, to ensure high strength and wear resistance.

[0057] Finally, in order to optimize the avoidance space when the interchangeable auxiliary table 30 is turned over and stored, refer to Figure 6 Two avoidance gaps 03 are provided on the right-angle guide rail 41. The spacing between the two avoidance gaps 03 is the same as the spacing between the two sliding connectors 42, and the width of the avoidance gap 03 is slightly larger than the width of the sliding connector 42. Furthermore, the position of the avoidance gap 03 in the extension direction of the right-angle guide rail 41 is optimized. Specifically, when turning, the rear sliding connector 42 rotates out of the avoidance gap 03 close to the adaptive pivot 43. The specific position of the avoidance gap 03 is reasonably allocated according to the position of the adaptive pivot 43. These improved designs significantly improve the functionality and stability of the workbench, enabling it to better adapt to complex and changing work requirements.

[0058] The present invention further optimizes the flip stability of the interchangeable auxiliary table 30. Specifically, a center hole 04 is opened on the outer convex arc surface 421, and a flip pin 05 is installed at the end of the right-angle guide rail 41. The flip pin 05 is coaxial with the inner concave arc surface 411, and the free end faces the center, which is used to cooperate with the center hole 04, thereby improving the flip stability of the interchangeable auxiliary table 30.

[0059] The multi-mode sliding controller 44 is one of the core components of the present design, and is fixed on the interchangeable auxiliary table 30 between the two sliding connectors 42, and its upper surface is flush with or slightly lower than the interchangeable auxiliary table 30. Its structure and function are as follows:

[0060] 1) Operating unit body 441: The shape is a disc with a corner cut off vertically, with a pin 06 on the cut surface and a screw hole 07 in the center. The operating unit body 441 is embedded in the upper surface of the replaceable auxiliary table 30 and is made of wear-resistant alloy materials such as 7075 aviation aluminum alloy to ensure stability in long-term use.

[0061] 2) Lower fixing member 442: located on the lower surface of the replaceable auxiliary table 30, the operating part body 441 is fixed to the replaceable auxiliary table 30 by bolts. It is made of high-strength stainless steel material, which has corrosion resistance and good strength characteristics.

[0062] 3) Dual-function spiral actuator 443: The main body 08 is a bolt, and its thread is spirally installed in the screw hole 07. The handle of the bolt is on the upper surface of the operating part body 441, and a dual-function head 081 is fixedly installed on the head. The dual-function head 081 includes a locking and pressing part 082 (a circular ring structure with a diameter 5mm larger than the main body 08 and a thickness of 2mm) and a pushing part 083 (located below the locking and pressing part 082, cylindrical, with the same diameter as the main body 08 and a height of 5mm). The material is high-strength alloy steel with surface hardening treatment to improve wear resistance.

[0063] 4) Guide and pivot fitting 444: The shape is a disc with a corner cut off vertically, with an arc-shaped protrusion 09 on the cut surface, a spherical arc surface at the bottom (such as a curvature radius of 50mm), a guide surface 01 set on the spherical arc surface, and a matching hole 02 set in the center. High-performance self-lubricating engineering plastics are used to reduce friction.

[0064] 5) Limiting member 445: The whole is a plate structure, with a waist hole 4451 at one end to fit with the pin 06, and an arc groove 4452 at the other end to match and fit with the arc protrusion 09. The arc length of the arc protrusion 09 is smaller than the arc groove 4452. This design enables the guide and pivot fitting member 444 to have two degrees of freedom: the vertical direction is limited by the combination of the waist hole 4451 and the pin 06, and the horizontal plane swing along the extension direction of the right-angle guide rail 41 is limited by the arc groove 4452 and the arc protrusion 09. It uses elastic alloy materials such as beryllium copper alloy, which has both strength and elasticity.

[0065] 6) Elastic member 446: It adopts a compression spring design, one end of which abuts against the lower surface of the operating part body 441, and the other end abuts against the upper surface of the guide and pivot fitting 444. It is made of stainless steel, and the preload is, for example, 50N, to ensure the sensitive response and stability of the mechanism.

[0066] This carefully designed multi-mode sliding controller 44 greatly improves the operational flexibility and stability of the interchangeable auxiliary table top 30, allowing the workbench to better adapt to various complex working environments and requirements.

[0067] Working principle, refer to all attached Figure 1-13 :

[0068] The working principle of the multi-mode sliding controller 44 covers five main aspects: position adjustment, steering preparation, steering process, reversing completion and locking mechanism. In the position adjustment stage, the operator rotates the main body 08 to make it rise, thereby releasing the pressure of the locking top pressure part 082 on the guide and pivot fitting 444, and at the same time releasing the locking state of the two sliding connectors 42, so that the interchangeable auxiliary table 30 can slide freely. The steering preparation stage utilizes the design freedom of the guide and pivot fitting 444 and the elastic expansion and contraction ability of the adaptive pivot 43 in the vertical direction. It only needs to push the interchangeable auxiliary table 30 to one side of the adaptive pivot 43 to complete the docking of the matching hole 02 and the adaptive pivot 43. The steering process includes four steps: after the docking is completed, the steering is started; the sliding connector 42 located in the front directly slides off the track; when the interchangeable auxiliary table 30 rotates, the sliding connector 42 located in the rear rotates out from the corresponding avoidance gap 03; after completing the 90-degree rotation, the sliding connector 42 originally located in the front rotates into the new track from another avoidance gap 03. When the reversal is completed, the operator rotates the main body 08 so that the push portion 083 contacts the adaptive pivot 43, and gradually disengages the adaptive pivot 43 from the matching hole 02, and then pushes the interchangeable auxiliary table 30 to complete the reversal. Finally, the position locking is achieved by rotating the main body 08 so that the locking push portion 082 presses the guide and pivot matching piece 444, so that it is in close contact with the right-angle guide rail 41, so that the position of the interchangeable auxiliary table 30 can be firmly locked. This design realizes the flexible adjustment, smooth steering and stable locking of the interchangeable auxiliary table 30, which can adapt to various work needs. Its operation is simple and intuitive, and does not require a complex external power system. It is particularly suitable for use in various environments, greatly improving the functionality and practicality of the workbench.

[0069] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
