[0020] Reference will now be made in detail to embodiments of the present disclosure, one or more of which are set forth herein. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0021] like Figures 1-3 The present invention discloses a sliding platform power supply device, including a guide rail 1 and a sliding platform 2, wherein the sliding platform 2 is slidably mounted on the guide rail 1; a power supply unit is provided on the guide rail 1, and a sliding contact structure 25 is provided on the sliding platform 2 for abutting against the power supply unit to supply power to the equipment on the sliding platform 2. The sliding contact structure 25 is provided with a metal sliding contact 252 that elastically abuts against the power supply unit, and the metal sliding contact 252 is electrically connected to the equipment through a cable for power transmission.

[0022] In one specific embodiment, the present invention has two sets of power supply units, which are symmetrically arranged about the guide rail 1. The sliding contact structure 25 corresponds to the position of one set of power supply units to transmit power. The sliding platform 2 is located below the other power supply unit and corresponds to the signal sensor 26. The power connection status is determined by the signal sensor 26, which facilitates the troubleshooting of the sliding platform status. Alternatively, the number of power supply units can be increased as needed, or all power supply units can be used to supply power to the equipment on the sliding platform 2.

[0023] The sliding platform 2 of this utility model is provided with an adjustment mechanism for moving the sliding contact structure 25 and the signal sensor 26 closer to or further away from the power supply unit. The adjustment mechanism enables the two to work closely with the power supply unit to stably transmit power or signals.

[0024] The adjustment mechanism of this utility model includes an adjustment plate 21 and a screw 23 whose end is rotatably engaged with the adjustment plate 21. The adjustment plate 21 is slidably engaged with the sliding platform 2 along the adjustment movement direction. The screw 23 passes through the sliding platform 2 and is threadedly engaged with the sliding platform 2. By rotating the screw 23, the adjustment plate 21 is moved to adjust the position of the sliding contact structure 25 or the signal sensor 26. A base 24 for mounting the signal sensor is provided on the adjustment plate 21 corresponding to the signal sensor 26.

[0025] In an embodiment of this utility model, the moving direction of the adjusting mechanism is... Figure 3 The sliding platform 2 is provided with lifting holes 22 for cooperating with the adjusting plate 21 in the vertical direction. The partial surface of the adjusting plate 21 and the screw 23 are located in the area where the lifting holes 22 are located.

[0026] The elastic contact of the metal sliding contact 252 of this utility model is achieved through a spring structure, such as... Figure 3 As shown, the sliding contact structure 25 includes a movable seat 251 and an insulating spring 253. The movable seat 251 has a mounting hole, and the metal sliding contact 252 is disposed in the mounting hole. One end of the insulating spring 253 is fixedly connected to the metal sliding contact 252, and the other end is fixed in the mounting hole. A cable hole is provided on the movable seat 251 for the corresponding cable to pass through. After the cable passes through, it is connected to the equipment through the connecting wire hole 3 provided on the surface of the sliding platform 2.

[0027] To further improve power extraction efficiency and maintain stable power transmission, the power supply unit of this utility model includes a conductive contact plate 8 arranged along the length of a guide rail 1. The guide rail 1 has a corresponding mounting groove for installing the conductive contact plate 8. An insulating protective cover 7 is installed within the mounting groove. The conductive contact plate 8 is disposed within the protective cover 7 and connected to a terminal block 5 located at the end of the guide rail. The terminal block 5 is mounted on a sealing cover 6 at the end of the guide rail. The sealing cover 6 fixes the terminal block 5 while simultaneously sealing and protecting the area where the conductive contact plate is located. The conductive contact plate 8 is respectively equipped with… The neutral and live wires are positioned, with the neutral wire on one side of the operating surface to prevent electric shock. The conductive contact plate 8 and the metal sliding contact 252 adopt a matching arc structure between their contact surfaces. Under the rebound force of the insulating spring 253, the conductive contact plate 8 and the metal sliding contact 252 are in close contact, which can ensure stable power transmission. Preferably, the material hardness of the metal sliding contact 252 of this invention should be lower than that of the conductive contact plate 8. As the component that wears out first, the metal sliding contact 252 is easy to replace and maintain, and at the same time, it can make the two fit better and play a certain lubrication role.

[0028] For situations where the signal sensor 26 is required to detect power connection, a shielding cover 4 can be installed on the outside of the protective cover 7 as needed, or the protective cover 7 can be made of a material that can shield signals, so as to avoid interference with the signal transmission of the sensor.

[0029] In use, during the sliding motion of the sliding platform 2, the adjusting plate 21 can slide within the lifting hole 22 at the bottom of the sliding platform 2 by rotating the screw 23. When the adjusting plate 21 rises, the metal sliding contact 252 contacts the bottom side wall of the conductive contact plate 8, ensuring power transmission. To ensure close contact between the conductive contact plate 8 and the metal sliding contact 252 during the sliding process of the sliding platform 2, the insulating spring 253 is adjusted to a compressed state in the power-on state. This ensures that the metal sliding contact 252 and the surface of the conductive contact plate 8 are in close contact under the rebound force of the insulating spring 253, and can compensate for wear of the contact surface over long-term use, thus ensuring stable power transmission.

[0030] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
