Description

Technical Field

[0001] The utility model relates to the technical field of support platforms, in particular to a lifting mechanism for a support platform. Background Art

[0002] In modern life, support tables are a common appliance widely used in various occasions, such as offices, home study rooms, kitchens, conference rooms, exhibition halls, etc. The design of their lifting mechanisms is directly related to the user experience and the market competitiveness of the product. With the continuous advancement of technology and the increasing maturity of the market, the lifting mechanisms for support tables have achieved significant improvements in function, performance and design, but there are still deficiencies in many aspects:

[0003] 1. Insufficient lifting stability and noise control: When the lifting mechanism drives the support table to lift, it is easy to shake or tilt, which is particularly obvious when the support table carries heavy objects. This lack of stability not only reduces the safety and user experience, but also easily causes interference between the structural components of the support table during the lifting process, generating loud noise and reducing the service life of the product;

[0004] 2. Disassembly and maintenance are inconvenient: the overall structure of the lifting mechanism is relatively complex. Once a fault occurs, it is often difficult for users to solve it by themselves and they often rely on professional maintenance personnel, which increases the difficulty of disassembly and maintenance costs for users;

[0005] 3. The lifting drive components have high power and high energy consumption: The lifting and lowering process of the support platform is purely dependent on the lifting drive of the lifting drive components. The power of the selected lifting drive components is generally large, which not only increases energy consumption, but also the lifting drive components are prone to shortening their service life due to bearing a large load alone, which increases both manufacturing and maintenance costs;

[0006] 4. Limited scope of application: The design of the support table lifting mechanism is usually based on specific specifications and styles, which leads to significant adjustment limitations when facing support tables with different materials and specifications. This makes the lifting mechanism appear to be stretched when adapting to diverse application scenarios, thus greatly limiting its scope of application. Utility Model Content

[0045] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0046] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0047] In various fields of modern society, the support table is an indispensable tool, and the design of its lifting mechanism has become a key factor in determining user satisfaction and market competitiveness. However, there are still many problems to be optimized in the lifting mechanisms currently on the market. First, the stability and noise control during the lifting process are still insufficient, especially when carrying heavy objects, which can easily cause shaking, tilting and interference of structural components, which not only reduces the safety of use, but also brings unpleasant noise and may shorten the life of the product. Secondly, the complex structure of the lifting mechanism makes disassembly and maintenance difficult. Users often find it difficult to solve the problem by themselves and need to rely on professional maintenance personnel, which undoubtedly increases the maintenance cost and inconvenience of users. Furthermore, in order to meet the needs of objects of different weights, the lifting drive components usually adopt a high-power design, which not only increases energy consumption, but also easily causes components to wear out due to excessive load, which increases both manufacturing costs and long-term maintenance costs. Finally, limited by the design of specific specifications and styles, the current lifting mechanism shows significant limitations in adapting to diverse application scenarios, which greatly limits its scope of application.

[0048] To solve the above problems, please refer to Figures 1 to 5 The embodiment of the utility model provides a lifting mechanism for a support platform, comprising:

[0049] The driving motor 14 is used to provide stable lifting power to drive the support platform to move up and down, thereby ensuring the reliability of the support platform during the lifting process.

[0050] The support column 20 is disposed at the bottom of the support platform as one of the load-bearing components of the support platform. There are multiple support columns 20 to provide a balanced supporting force. A first through cavity 21 is defined in the support column 20 .

[0051] The elastic energy storage element 30 can be adjustably installed in the first through cavity 21. The setting of the first through cavity 21 provides space for the installation and adjustment of the elastic energy storage element 30. One end of the elastic energy storage element 30 passes through one end of the first through cavity 21 and is connected to the support table. The elastic energy storage element 30 is used to enhance the lifting effect of the support table and plays an auxiliary supporting role. The adjustable installation method can meet the auxiliary support requirements of support tables of different specifications and styles, thereby expanding the scope of use.

[0052] When the lifting mechanism is in the initial state, the elastic energy storage element 30 is in a compressed state, and the elastic energy storage element 30 provides a lifting force for the support platform.

[0053] Specifically, when the support platform is gradually lifted, the elastic energy storage element 30 gradually transforms to a non-compressed state, assisting the drive motor 14 in lifting the support platform, so that the support platform can be stably lifted, improving the overall stability of the lifting mechanism, and ensuring good performance. When the support platform is gradually lowered, the elastic energy storage element 30 gradually transforms to a compressed state, absorbing the impact force of the support platform during the lowering process, and offsetting part of the gravity of the support platform, reducing the impact load of the support platform on the drive motor 14 and the support column 20, achieving a smooth descent while reducing noise and wear, and improving the product's service life and the user's experience.

[0054] Among them, see Figure 2 and Figure 3 , the elastic energy storage element 30 comprises:

[0055] The elastic member 33 is a key component for storing energy in the elastic energy storage element 30 .

[0056] The top connecting member 31 is movably installed in the first through cavity 21 and can reciprocate along the length direction of the first through cavity 21. One end of the top connecting member 31 passes through the first through cavity 21 and is connected to the support platform. The top connecting member 31 serves as one of the direct force points for the lifting and lowering of the support platform. During the lifting, the support platform can obtain direct support and a stable lifting trajectory.

[0057] The adjusting member 32 is adjustably installed at one end of the first through cavity 21 away from the top connecting member 31, and the elastic member 33 is arranged between the top connecting member 31 and the adjusting member 32. The adjusting member 32 is connected to the top connecting member 31 through the elastic member 33. The adjusting member 32 is used to adjust the compression degree of the elastic member 33 in the initial state to meet the auxiliary support requirements of support platforms of different specifications and styles. The elastic recovery stroke of the elastic member 33 is not less than the lifting stroke of the support platform driven by the driving motor 14.

[0058] In a preferred solution, when the lifting mechanism is in the initial state, one end of the top connecting member 31 connected to the support platform is flush with the end of the support column 20 close to the support platform. At this time, the elastic energy storage element 30 is in the optimal energy storage state.

[0059] Specifically, when the lifting mechanism is in the initial state, by adjusting the adjusting part 32, the user can conveniently adjust the compression amount of the elastic part 33, and thereby adjust the energy storage size of the elastic energy storage element 30, so as to meet the dynamic response requirements and stability requirements of the support platform during the lifting process, and thus adapt to different lifting requirements and load conditions, which not only increases the flexibility and adaptability of the lifting mechanism, but also ensures the safety and stability of the lifting process, so that the support platform can be more stable and safe during lifting, and effectively extends the service life of the lifting mechanism.

[0060] See also Figure 3 and Figure 5 An external thread 322 is provided on the outer peripheral side of the adjusting member 32, and an internal thread 221 matching the external thread 322 is provided on the end of the first through cavity 21 away from the top connecting member 31. Through the thread matching, not only the stability and strength of the structural connection are enhanced, but also the precise positioning and fixation between the adjusting member 32 and the first through cavity 21 are achieved, which effectively improves the adjustment accuracy and stability of the lifting mechanism.

[0061] In Example 1, please refer to Figure 2 and Figure 3 The axial end surface of the adjusting member 32 is convexly provided with a guide rod 321, and the elastic member 33 is sleeved on the guide rod 321. The top connecting member 31 is provided with a mounting cavity 312 adapted to the guide rod 321. The end of the guide rod 321 away from the adjusting member 32 is penetrated in the mounting cavity 312 and movably connected with the top connecting member 31. The setting of the guide rod 321 not only provides reliable support for the elastic member 33, but also facilitates the adjustment of the compression amount of the elastic member 33 by the adjusting member 32 to avoid the slippage of the elastic member 33 to meet different usage requirements. The opening of the mounting cavity 312 not only ensures the stability of the top connecting member 31 during the lifting process, but also allows it to be flexibly adjusted according to needs, thereby ensuring the smooth operation and high efficiency of the entire lifting mechanism.

[0062] In Example 2, please refer to Figure 3 The first limit block 311 is convexly provided on the outer peripheral side of one end of the top connecting member 31 connected to the elastic member 33, and the second limit block 22 corresponding to the first limit block 311 is provided on the end of the first through cavity 21 close to the support platform, which effectively limits the movement range of the top connecting member 31 in the axial direction, ensuring that the top connecting member 31 can move stably without excessive displacement when subjected to the force of the elastic member 33, and at the same time enhances the stability of the top connecting member 31 during the lifting process, prevents it from shaking or deviating when subjected to external force, and ensures the stability and accuracy of the lifting and lowering of the support platform.

[0063] In Example 3, please refer to Figure 2The first limit block 311 is convexly provided on the outer peripheral side of one end of the top connecting member 31 connected to the elastic member 33, and the first guide limit groove 23 matched with the first limit block 311 is opened in the first through cavity 21. The existence of the first guide limit groove 23 ensures that the first limit block 311 can move smoothly therein, effectively avoiding the top connecting member 31 from deflecting or rotating during the lifting process, further enhancing the stability and reliability of the lifting mechanism. This design not only improves the operating accuracy of the lifting mechanism, but also extends its service life.

[0064] In Example 4, please refer to Figures 1 to 3 The lifting mechanism for the support platform also includes:

[0065] The support seat plate 40 serves as the base of the entire lifting mechanism and plays a supporting role in the overall structure. The support column 20 can be detachably installed on the support seat plate 40. This design facilitates installation and disassembly, and is also convenient for maintenance. The first through cavity 21 passes through the bottom of the support seat, which is convenient for the disassembly, assembly and adjustment of the elastic energy storage element 30, so that the elastic energy storage element 30 can fully play its role in the entire lifting process of the support platform.

[0066] The control unit is electrically connected to the drive motor 14 and is used to control the lifting and lowering operation of the support platform by the drive motor 14. Through the control unit, the user can conveniently control the lifting height and speed of the support platform to achieve precise adjustment. The drive motor 14 is installed on the support seat plate 40 to ensure the stability and reliability of the structural installation.

[0067] The connecting plate 50 is used to support and connect the support platform, and serves as a connecting bridge between the support platform and the drive motor 14 and the elastic energy storage element 30. One end of the elastic energy storage element 30 and the action end of the drive motor 14 are connected to the support platform through the connecting plate 50. This design enables the elastic energy storage element 30 and the drive motor 14 to act on the support platform together to achieve a stable and efficient lifting effect. At the same time, the existence of the connecting plate 50 also makes the connection between the support platform and the lifting mechanism more firm and reliable.

[0068] For further information, see Figure 1 and Figure 4The driving motor 14 is installed on the supporting seat plate 40 through the installing bracket 11, which ensures the installation stability of the driving motor 14 and facilitates the maintenance and replacement of the driving motor 14. A guide limit column 12 is provided on the installing bracket 11, and a second through cavity 121 is opened in the guiding limit column 12. A lifting top piece 15 is movably installed in the second through cavity 121. One end of the lifting top piece 15 passes through the second through cavity 121 and is connected to the supporting platform through the connecting plate 50. The driving end of the driving motor 14 is connected to the driving screw 13, and the driving screw 13 is rotatably installed on the module bracket. The lifting top piece 15 is screwed with the driving screw 13. This design enables the lifting top piece 15 to move up and down with the rotation of the driving screw 13, thereby driving the supporting platform to be lifted and lowered.

[0069] In a preferred solution, the drive motor 14 is installed at the core of the support seat plate 40, and a plurality of support columns 20 are arranged at equal intervals along the outer peripheral side of the drive motor 14 and are detachably connected to the support seat plate 40, so that during the lifting process of the support platform, each support column 20 is subjected to uniform force, thereby further improving the lifting stability of the support platform and avoiding the occurrence of interference between components caused by uneven force on each support column 20, thereby further reducing the generation of noise, reducing wear between components, and extending the service life.

[0070] It should be noted that the provision of the second through cavity 121 on the guide limit column 12 not only provides stable support for the lifting top member 15 , but also ensures the linear motion trajectory during the lifting process, and ensures the accuracy and reliability of the lifting action.

[0071] Furthermore, a third limiting protrusion 151 is provided at one end of the lifting top member 15 away from the support platform, and a second guide limiting groove 122 matched with the third limiting protrusion 151 is opened on the inner wall of the second through cavity 121. The second guide limiting groove 122 provides precise guiding and limiting functions for the third limiting protrusion 151, ensuring that the lifting top member 15 is not easily deviated from the predetermined track during the lifting process, ensuring the accuracy and stability of the lifting top member 15 during the lifting process, and improving the reliability and service life of the entire lifting mechanism. The transmission end of the drive motor 14 is rotatably connected to the transmission screw 13 through a bevel gear transmission component 16. The setting of the bevel gear transmission component 16 makes the lifting mechanism compact in structure while ensuring the high efficiency and stability of the transmission, so that the transmission screw 13 can rotate accurately and stably, thereby realizing precise control and smooth operation of the lifting mechanism.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
