Description

Technical Field

[0001] This invention relates to the field of track device mechanism technology, specifically a synchronous electric track device. Background Technology

[0002] Current track devices include a rotating wheel, a rotary drive, a mounting component, and a primary slide rail. The rotating wheel is wound with a flexible cable, adapted to move with the rotation of the wheel, and includes cable segments located on both sides of the rotating wheel. The rotary drive is connected to the rotating wheel and adapted to drive its rotation. The mounting component is equipped with a guide rail and a first fixed pulley. The primary slide rail is adapted to slide relative to the guide rail. The flexible cable passes over the first fixed pulley, and the cable segments located on both sides of the rotating wheel are connected to the primary slide rail. When the flexible cable becomes slack, it affects the transmission effect, and the stability of the track device during sliding deteriorates.

[0003] However, the above-mentioned track device structure has the following shortcomings:

[0004] 1) The assembly efficiency of the flexible cable is low. The transmission space between the rail bodies is small and there are many parts. At the same time, the flexible cable is relatively soft, which makes it easy to make the assembly of the flexible cable difficult, reduce the assembly efficiency, or even fail to assemble properly, affecting the transmission stability.

[0005] 2) The flexible cable transmission has poor stability. The flexible cable should be under moderate tension after assembly, but after a long period of use, the tension of the flexible cable cannot be adjusted, which can easily cause it to loosen and seriously affect the track transmission effect.

[0006] 3) The existing track system has asynchronous operation of each track body, which can cause the track system to jam and reduce the operational stability of the product. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a synchronous electric track device with a compact structure, electric drive for opening and closing, convenient assembly, and tension adjustment function.

[0032] The present invention will now be further described with reference to the accompanying drawings.

[0033] According to the appendix Figures 1 to 8 As shown in the figure, the synchronous electric track device of the present invention includes a fixed rail 1, a moving rail 2, and an inner rail assembly 3 slidably connected between the fixed rail 1 and the moving rail 2. The fixed rail 1 is equipped with a drive assembly for automatically opening and closing the inner rail assembly 3. The drive assembly includes a motor 4, an active traction group 5, an active pulley 6, and a driven pulley 7. The motor 4 is mounted on the fixed rail 1, and its output shaft is connected to the shaft of the active pulley 6. The driven pulley 7 is mounted on the fixed rail 1. One end of the active traction group 5 is positioned and connected to the active pulley 6, and the other end of the active traction group 5 passes around the driven pulley 7 and is positioned and connected to the inner rail assembly 3.

[0034] Through the coordinated structure of the drive assembly's motor 4, active traction group 5, active pulley 6, and driven pulley 7, when the motor 4 is activated, it drives the active pulley 6, causing the active traction group 5 to rotate along with the active pulley 6, thereby pulling the inner rail assembly 3 to move. This achieves automatic opening or closing of the track device using an electric drive method. The structure is compact, easy to assemble, provides stable transmission, is easy to operate, and has strong applicability.

[0035] Reference Figures 1 to 8As shown, further detailed, the active traction group 5 includes a first active traction line 51 and a second active traction line 52. One end of the first active traction line 51 and the second active traction line 52 are respectively matched and clamped to the active spool 6. The other end of the first active traction line 51 is matched and clamped to the inner rail assembly 3. The other end of the second active traction line 52 passes around the driven wheel 7 and is matched and clamped to the inner rail assembly 3.

[0036] That is, when the motor 4 is activated, it drives the drive pulley 6 to rotate, thereby pushing the first drive traction line 51 or pulling the second drive traction line 52, thereby driving the inner rail assembly 3 forward or backward, and thus causing the track device to move forward or backward, realizing the automatic opening or closing of the track device in an electric manner.

[0037] The active spool 6 is equipped with a snap-fit ​​plate 12 that rotates accordingly. The snap-fit ​​plate 12 has a snap-fit ​​groove 13 for engaging with the ends of the first active traction line 51 and the second active traction line 52.

[0038] Additionally, a positioning block 14 is installed on the inner side of the inner rail assembly 3. The positioning block 14 is provided with positioning slots 15 that are distributed vertically and can be fitted with the other end of the first active traction line 51 and the second active traction line 52.

[0039] The snap-fit ​​plate 12 and positioning block 14 of this structure enable the first active traction line 51 and the second active traction line 52 to be quickly assembled, with high connection stability and ensuring smooth transmission.

[0040] Reference Figures 1 to 8 As shown in the diagram, further details are provided. At the end of the fixed rail 1, a motor bracket 16 is provided for mounting the motor 4. The motor bracket 16 is equipped with a main adjustment component for adjusting the transmission tension of the active traction group 5. The movable part of the main adjustment component slides up and down on the motor bracket 16. A transmission section of the active traction group 5 is connected to the movable part of the main adjustment component and moves up and down with the movable part of the main adjustment component.

[0041] The main adjustment assembly includes a main adjustment bolt 17, a main adjustment movable frame 18, and a main adjustment wheel 19. The main adjustment movable frame 18 is slidably mounted on the motor bracket 16. The main adjustment wheel 19 is rotatably connected to the main adjustment movable frame 18 and is tumbledly connected to the first active traction line 51 of the active traction group 5. One end of the main adjustment bolt 17 rotates on the motor bracket 16, and the other end of the main adjustment bolt 17 is threadedly connected to the main adjustment movable frame 18.

[0042] With the structure of the main adjustment assembly, simply rotating the main adjustment bolt 17 will move the main adjustment movable frame 18 up or down, causing the main adjustment wheel 19 to move up or down while simultaneously pulling the first active traction line 51 to deform up or down. This adjusts the overall transmission path stroke of the first active traction line 51, thereby adjusting the overall tension of the active traction group 5, ensuring transmission tension, strengthening transmission stability, preventing the active traction group 5 from loosening, and ensuring the quality of the track device.

[0043] Reference Figures 1 to 8 As shown, the inner rail assembly 3 is equipped with a synchronous running component for synchronously operating the moving rail 2 under the drive of the drive component. The synchronous running component includes a synchronous opening component 8 and a synchronous closing component 9. The synchronous opening component 8 and the synchronous closing component 9 are respectively installed at both ends of the inner rail assembly 3, and the synchronous opening component 8 is equipped with an opening linkage member 10, one end of which is positioned and connected to the fixed rail 1, and the other end of which is positioned and connected to the moving rail 2. The synchronous closing component 9 is equipped with a closing linkage member 11, one end of which is positioned and connected to the fixed rail 1, and the other end of which is positioned and connected to the moving rail 2.

[0044] The synchronous opening component 8 includes an opening linkage 10 and a first synchronous rolling component 81, and the synchronous closing component 9 includes a closing linkage 11 and a second synchronous rolling component 91. The first synchronous rolling component 81 and the second synchronous rolling component 91 are symmetrically installed at the front and rear ends of the inner rail component 3, respectively. The opening linkage 10 is wound around the first synchronous rolling component 81, and its two ends are respectively engaged with the moving rail 2 and the fixed rail 1; the closing linkage 11 is wound around the second synchronous rolling component 91, and its two ends are respectively engaged with the moving rail 2 and the fixed rail 1.

[0045] When the motor 4 is activated, it drives the inner rail assembly 3 to move outward, and the opening linkage 10 moves accordingly. Since one end of the opening linkage 10 is fixed to the fixed rail 1 and the other end of the opening linkage 10 is engaged with the moving rail 2, the opening linkage 10 pulls the moving rail 2 to move outward, so that the track device opens synchronously.

[0046] When the motor 4 reverses and drives the inner rail assembly 3 to move inward, the closing linkage moves accordingly. Since one end of the closing linkage is fixed to the fixed rail 1 and the other end of the closing linkage is engaged with the moving rail 2, the closing linkage pulls the moving rail 2 inward to achieve synchronous closing of the track device.

[0047] The synchronous opening component 8 and synchronous closing component 9 of the synchronous operation components work together to achieve synchronous opening and closing of the track device, avoiding jamming caused by asynchronous operation between the track bodies, ensuring synchronous operation and reliability.

[0048] Reference Figures 1 to 8As shown in the figure, further detailed, the first synchronous rolling element 81 includes a first rolling wheel 811, a synchronous movable frame 812, and a tension adjusting bolt 813. The front end of the inner rail assembly 3 is provided with a connecting groove 31. The synchronous movable frame 812 is slidably mounted on the connecting groove 31. One end of the tension adjusting bolt 813 is rotatably connected to the end of the inner rail assembly 3, and the other end of the tension adjusting bolt 813 is threadedly connected to the synchronous movable frame 812. The synchronous movable frame 812 is equipped with a first rolling shaft. The first rolling wheel 811 is rotatably connected to the first rolling shaft. The outer edge of the first rolling wheel 811 has a first transmission groove for winding with the closing linkage element 11.

[0049] Furthermore, the second synchronous rolling element 91 includes a second rolling wheel 911. The rear end of the inner rail assembly 3 is provided with a mounting groove 32, the mounting groove 32 is used to mount a second rolling shaft, the second rolling wheel 911 is rotatably connected to the second rolling shaft, and the outer edge of the second rolling wheel 911 has a first transmission groove for winding with the closing linkage element.

[0050] In this way, the first synchronous rolling element 81 and the second synchronous rolling element 91 can be adapted and assembled through the mounting groove 32 and the connecting groove 31 provided in the same rail assembly, which simplifies the assembly, reduces the space occupied by the assembly, and ensures the assembly quality of the product.

[0051] Meanwhile, in conjunction with the structure of the first synchronous rolling element 81, the tension of the closing linkage element 11 can be adjusted simply by rotating the tension adjusting bolt 813, thereby adjusting the tension of the synchronous running components, enhancing the synchronous operation, avoiding synchronous failure, ensuring the smooth and stable operation of the product, and ensuring the quality of product use.

[0052] Furthermore, by employing the second synchronous rolling element 91 of this structure, the opening linkage element 10 can be quickly wound in, making assembly convenient and easy to operate, reducing the impact of assembly space, and ensuring the stability of synchronous transmission.

[0053] Additionally, it is worth noting that the first active traction line 51 and the second active traction line 52 of the active traction group 5 can be selected as linkage ropes. The opening linkage 10 and the closing linkage 11 are respectively set as linkage ropes or linkage belts.

[0054] In this way, by selecting appropriate components based on actual applications, the product is highly adaptable and its stability in use is ensured.

[0055] The above specific embodiments are merely specific implementations of the present invention with better effects. Any structure that is the same as or equivalent to the synchronous electric track device of the present invention is within the protection scope of the present invention.
