[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.
[0028] Example 1
[0029] like Figures 1-4 As shown, a power supply device for a guide rail trolley, which draws power from a power output device, includes: Two conductive plates 1 are arranged parallel to each other along the direction of movement of the guide rail trolley, and serve as the positive and negative terminals of the power output device, respectively. Mounting base 3 is arranged on the guide rail trolley, and a sealing cavity 31 is provided on it; Electrical power transmission components, including: The conductive shaft 4 is rotatably connected to the mounting base 3 via the rolling pair assembly 5. A power-collecting roller 2 is arranged on it, and the power-collecting roller 2 collects power by rolling contact with the conductive sheet 1. The conductive shaft 4 transmits electrical energy to the outer ring 61 of the planetary gear set 6 via the planetary gear set 6. The planetary rollers are arranged in the sealed cavity 31. The power output component 7 is connected to the outer ring 61 of the planetary gear set 6 and is used to output the power transmitted by the planetary gear set 6 to the guide rail trolley. Seal 8 is arranged between conductive shaft 4 and mounting base 3 for sealing rolling pair assembly 5; The power transfer components are set in two sets, and the power-collecting rollers 2 in the two sets of power transfer components are respectively set to correspond to the two conductive plates 1.
[0030] By using the seal 8 to seal the rolling pair assembly 5 and the planetary gear set 6 to seal the sealing cavity 31, the metal ions generated by friction are not easily diffused, ensuring safe and reliable power supply. This application has a simple structure and is easy to disassemble and clean.
[0031] Example 2
[0032] The difference between this embodiment and embodiment 1 is that two sets of rolling pair components 5 are arranged between the conductive shaft 4 and the mounting base 3. The two sets of rolling pair components 5 are arranged along the axial direction of the conductive shaft 4, thereby improving the stability of the rotational connection between the conductive shaft 4 and the mounting base 3.
[0033] The mounting base 3 has a mounting hole, in which the rolling pair assembly 5 is arranged, and the seal 8 is used to seal the mounting hole. The mounting hole provides space for the installation of the rolling pair assembly 5 and the sealing assembly, effectively achieving the sealing of the rolling pair assembly 5.
[0034] The outer ring 61 of the planetary gear set 6 is fixedly connected to the mounting base 3, thereby transmitting the electrical energy from the conductive shaft 4 to the planetary gear set 6 to the outer ring 61 of the planetary gears through contact power extraction.
[0035] like Figure 4 The power supply device for the guide rail trolley also includes a sealing plate 32. The sealing cavity 31 is opened at the top of the mounting base 3. The sealing plate 32 seals the sealing cavity 31. The planetary gear set 6 can be observed by opening the sealing plate 32, which facilitates the maintenance and replacement of the planetary gear set 6.
[0036] The mounting base 3 has a power-collecting roller mounting cavity, which opens to the side facing the conductive sheet 1. The power-collecting roller 2 makes rolling contact with the conductive sheet 1 through the opening. This can, to a certain extent, prevent the diffusion of metal particles from the power-collecting roller 2 into the air, thus improving power collection safety.
[0037] The seal 8 is rotatably connected to the conductive shaft 4, and lubricant is added between the seal 8 and the conductive shaft 4.
[0038] The rolling pair assembly 5 is a bearing. The outer ring 61 of the bearing is fixed to the mounting base 3, and the inner ring of the bearing is fixed to the conductive shaft 4. This ensures smooth rotation of the conductive shaft 4 and improves power extraction efficiency.
[0039] In this embodiment, two conductive sheets 1 are arranged vertically, the conductive shaft 4 is vertical, and the power-collecting rollers 2 corresponding to the two conductive sheets 1 are also arranged vertically. This allows power to be collected during the movement of the guide trolley. The rolling contact between the two reduces the rolling friction force, thus reducing the metal particles generated by the friction between the power-collecting rollers 2 and the conductive sheets 1.
[0040] In this embodiment, the power output component 7 includes a positive electrode plate and a negative electrode plate. The positive electrode plate is connected to the power transfer component that is connected to the conductive plate 1 of the positive electrode of the power output device. The negative electrode plate is connected to the power transfer component that is connected to the conductive plate 1 of the negative electrode of the power output device.
[0041] During operation, the mounting base 3 moves along with the trolley on the track. The two power-collecting rollers 2 roll and contact the upper and lower conductive plates 1 (conductive copper plates are used in this embodiment) to collect electricity. The electricity is transmitted through the conductive shaft 4 to the planetary gear set 6 connected to it. The planetary gear set 6 rotates and transmits the electrical energy to the outer ring 61 of the planetary gear set 6 through the contact between the gear pairs. Then it is conducted to the positive and negative conductive plates and finally to the power-consuming components of the guide rail trolley, thus completing the power collection.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.
[0043] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
