A track conductive device for magnetic levitation sliding doors

Abstract

This utility model provides a track conductive device for magnetic levitation sliding doors, including a magnetic levitation track, a cylindrical body, pulleys, copper sheets, insulating sheets, and a power collection component. The pulleys are rotatably installed on the left and right sides of the cylindrical body, and the pulleys are slidably connected to the inner cavity of the magnetic levitation track. The insulating sheet is fixed to one side of the inner cavity of the magnetic levitation track, and the copper sheet is fixedly installed on the inner side of the insulating sheet. The power collection component is fixedly installed on the cylindrical body and is slidably electrically connected to the copper sheet. By fixing the copper sheet to one side of the inner cavity of the magnetic levitation track, as the cylindrical body moves along the magnetic levitation track via the pulleys, the conductive roller in the power collection component rolls along the copper sheet and makes electrical contact with the copper sheet. In this way, the current from the external power source can be transmitted to the power line connected to the door leaf through the copper sheet and the conductive roller, realizing the conductive function. Due to the use of a conductive structure of copper sheet and conductive roller, its structure is simpler and its manufacturing cost is lower.

Description

Technical Field

[0001] This utility model relates to the field of door and window track technology, specifically to a track conductive device for magnetic levitation sliding doors. Background Technology

[0002] Magnetic levitation sliding doors are a high-end door and window system based on magnetic levitation technology. They achieve contactless door operation by using the principle of "like poles repel and unlike poles attract" in magnetic fields, which completely changes the operation of traditional mechanical sliding doors and is therefore welcomed by the market.

[0003] The core of magnetic levitation sliding doors lies in the door panels levitating above the track, eliminating physical friction and achieving extremely quiet and smooth movement. Simultaneously, to power the door panels, a corresponding conductive device needs to be installed on the track. In existing technologies, the conductive device on the guide rail of a magnetic levitation sliding door typically includes a conductive track, brushes, connectors, and an insulating base. The conductive track is fixedly mounted on the insulating base, which is mounted on the sliding door track. The connector is mounted on the conductive track and connects an external power cord to it. The door panels make electrical contact with the conductive track through the brushes. Thus, as the door panels move relative to the track, the current in the conductive track is always transmitted to the door panels through the brushes, powering the corresponding electrical components (light sources) on the door panels. In the existing structures described above, because the conductive track needs to be installed inside the sliding door track, and the track is arranged along the length of the track, the structure of the magnetic levitation sliding door track conductive device is relatively complex and costly. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a track conductive device for magnetic levitation sliding doors that is simple in structure and low in cost.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This application provides a track conductive device for a magnetic levitation sliding door, including a magnetic levitation track, a cylindrical body, pulleys, copper sheets, insulating sheets, and a power collection component respectively disposed on the left and right sides of the cylindrical body. The pulleys are rotatably mounted on the left and right sides of the cylindrical body and are slidably connected to the inner cavity of the magnetic levitation track. The insulating sheet is fixed to one side of the inner cavity of the magnetic levitation track. The copper sheet is fixedly mounted on the inner side of the insulating sheet. The power collection component is fixedly mounted on the cylindrical body and is slidably electrically connected to the copper sheet. The power collection component is used to transmit the power collected by the copper sheet to the outer door panel.

[0006] Furthermore, the power acquisition assembly includes a mounting base, a pair of connecting arms, and a pair of return springs. The mounting base is fixedly installed at the bottom end of the cylindrical body. The pair of connecting arms are respectively installed horizontally and parallel to each other on the mounting base. The pair of connecting arms are laterally slidably installed in the inner cavity of the mounting base. The pair of return springs are respectively fitted onto the outer circumferential surface of one end of the connecting arms. The other end of the pair of connecting arms is rotatably mounted with a conductive roller, which forms a rolling contact with the inner end face of the copper sheet.

[0007] Furthermore, the mounting base includes a first base body and a second base body. Bolt holes are respectively provided on the first base body and the second base body. The first base body and the second base body are fixedly mounted on the bottom end of the cylindrical body by bolts installed in the bolt holes. A pair of parallel mounting grooves are provided on the second base body in the transverse direction. One end of each pair of connecting arms is slidably mounted in the mounting groove. The opposite ends of a pair of return springs are respectively abutted and compressed on one side of the bottom of the mounting groove and one end of the connecting arm. The return spring is used to make the conductive roller at the other end of the connecting arm fit against the inner wall of the copper sheet.

[0008] Furthermore, the first base is provided with a pair of observation holes to facilitate observation of the installation status of the pair of reset springs.

[0009] Furthermore, the pulley has a through hole at its center, through which the pulley is connected to the inner cavity of the cylindrical body.

[0010] The beneficial effects of this utility model are as follows: By fixing a copper sheet to one side of the inner cavity of the magnetic levitation track, the cylindrical body moves along the magnetic levitation track via pulleys. During this process, the conductive roller in the power collection component rolls along the copper sheet and makes electrical contact with the copper sheet. In this way, the current from the external power source can be transmitted to the power line connected to the door leaf through the copper sheet and the conductive roller, thus achieving the conductivity function. Due to the use of a conductive structure with a copper sheet and a conductive roller, the structure is simpler and the manufacturing cost is lower. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] See Figures 1 to 2 As shown, this embodiment provides a track conductive device 100 for a magnetic levitation sliding door, including a magnetic levitation track 10, a cylindrical body 30, pulleys 40, copper sheets 90, insulating sheets 20 and power collection components respectively disposed on the left and right sides of the cylindrical body 30. The cylindrical body 30 is arranged in the inner cavity of the magnetic levitation track 10, and the cylindrical body 30 is slidably installed in the inner cavity of the magnetic levitation track 10 by means of the pulleys 40 respectively disposed on its left and right sides.

[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the insulating sheet 20 is fixed to the inner side wall of the magnetic levitation track 10, and the copper sheet 90 is fixed to the inner side wall of the insulating sheet 20. The copper sheet 90 is arranged along the length of the magnetic levitation track 10. The power acquisition component is set at the bottom of the cylindrical body 30. The power acquisition component is used to guide the current transmitted from the outside to the copper sheet 90 to the door leaf below, for example, to power the light source on the door leaf.

[0020] In this design, a copper sheet 90 is fixedly installed on one side of the inner cavity of the magnetic levitation track 10. As the cylindrical body 30 moves along the magnetic levitation track 10 via the pulley 40, the conductive roller 80 in the power acquisition component rolls along the copper sheet 90 and makes electrical contact with it. In this way, the current from the external power supply can be transmitted to the power line connected to the door leaf through the copper sheet 90 and the conductive roller 80, thus achieving the conductivity function. Due to the use of the conductive structure of copper sheet 90 and conductive roller 80, the structure is simpler and the manufacturing cost is lower. Reference Figure 1 , Figure 3 and Figure 5 As shown, specifically in this embodiment, the power acquisition component includes a mounting base, a pair of connecting arms 70, and a pair of return springs 60. The mounting base is fixedly installed at the bottom end of the cylindrical body 30. The pair of connecting arms 70 are respectively horizontally parallel to the mounting base 50. The pair of connecting arms 70 and the mounting base 50 are horizontally slidably installed in the inner cavity of the mounting base 50. The pair of return springs 60 are respectively fitted on the outer circumferential surface of one end of the connecting arm 70. The other end of the pair of connecting arms 70 is rotatably mounted with a conductive roller 80. The conductive roller 80 forms a rolling contact with the inner end face of the copper sheet 90. The function of the return spring 60 is to apply lateral pressure to the connecting arm 70, that is, to apply lateral pressure to the connecting arm 70 towards the conductive roller 80, so that the conductive roller 80 always maintains stable contact with the copper sheet 90.

[0021] By employing the structure of a return spring 60, a connecting arm 70, and a conductive roller 80, the motion resistance formed between the conductive roller 80 and the copper sheet 90 is reduced during the movement of the power acquisition component following the cylindrical body 30, thus ensuring the smooth movement of the cylindrical body 30 along the magnetic levitation track 10. Furthermore, the placement of the return spring 60 ensures that the conductive roller 80 maintains stable contact with the copper sheet 90 throughout the movement, guaranteeing the stability of current transmission.

[0022] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the mounting base 50 adopts a split structure. The mounting base 50 includes a first base 51 and a second base 52. Bolt holes are respectively provided on the first base 51 and the second base 52. The first base 51 and the second base 52 are fixedly installed on the bottom end of the cylindrical body 30 by bolts 53 installed in the bolt holes.

[0023] The second base 52 has a pair of parallel mounting grooves 521 arranged horizontally, that is, the pair of mounting grooves 521 are arranged vertically opposite each other. One end of the pair of connecting arms 70 is slidably installed in the mounting grooves 521 respectively. The two ends of the pair of return springs 60 are respectively pressed against the bottom of the mounting groove 521 and one end of the connecting arm 70. The return springs 60 apply a horizontal pressing force to the connecting arm 70 in the direction of the conductive roller 80. The return springs 60 are used to make the conductive roller 80 at the other end of the connecting arm 70 fit against the inner wall of the copper sheet 90.

[0024] By using a split first seat 51 and second seat 52 to construct the mounting base 50, it is easier to install the connecting arm 70 and the return spring 60 on the mounting base 50, simplifying the installation process and making it easier for installers to perform the installation.

[0025] Reference Figure 2 and Figure 4 As shown, in this embodiment, the first base 51 is provided with a pair of observation holes 54 to facilitate observation of the installation status of a pair of return springs 60. The pair of observation holes 54 are directly opposite the installation position of the pair of return springs 60. Users can intuitively know the installation status of the return springs 60 on the connecting arm 70 through the observation holes 54, ensuring that the return springs 60 are in the normal installation state.

[0026] Reference Figure 3 As shown, in this embodiment, a through circular hole 41 is provided in the center of the pulley 40. The pulley 40 is connected to the inner cavity of the cylindrical body 30 through the circular hole 41. By providing a circular hole 41 in the center of the pulley 40, the power connection line on the door can enter the interior of the cylindrical body 30 through the circular hole 41 on the pulley 40 and be electrically connected to the conductive roller 80. In this way, the current introduced by the conductive roller 80 from the copper sheet 90 can be transmitted to the power connection line on the door to supply power to the light source on the door.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
