[0033] The utility model provides a quick-assembly conductive slip ring 100 .

[0034] See also Figure 1 and Figure 3 In one embodiment of the present invention, the quick-assembly conductive slip ring 100 includes a mounting bracket 1 , a brush 2 and a slip ring 3 ; the brush 2 is detachably connected to the mounting bracket 1 ; and the brush 2 is pressed against the slip ring 3 .

[0035] In the technical solution of this utility model, the brush 2 is detachably connected to the mounting bracket 1, allowing users to easily maintain or replace worn brushes 2 without disassembling the entire device. This significantly reduces maintenance time and costs, improving device availability. The brush 2 presses against the slip ring 3, ensuring that the brush 2 remains in contact with the slip ring 3 even during rotation, forming a conductive path and conducting electricity. Furthermore, the shape and size of the mounting bracket 1, brush 2, and slip ring 3 are easily adjustable, making them suitable for different types of equipment.

[0036] There are many ways to detachably connect. In one embodiment of the present invention, please refer to Figure 1 and Figure 3 The mounting bracket 1 is formed with a mounting portion 11; the brush 2 includes a mounting plate 21 and a plurality of brush filaments 22, all of which are arranged on the same side of the mounting plate 21, and all of which are pressed against the slip ring 3; the quick-assembly conductive slip ring 100 also includes a locking member, which passes through the mounting plate 21 and is screwed to the mounting portion 11 to fix the mounting plate 21. The brush 2 is composed of a mounting plate 21 and a plurality of brush filaments 22, all of which are arranged on the same side of the mounting plate 21 and are pressed against the slip ring 3. This design can ensure uniform contact between the brush 2 and the slip ring 3, and improve the stability and reliability of the electrical connection. At the same time, by screwing the locking member through the mounting plate 21 and the mounting portion 11, the mounting plate 21 can be fixed to ensure that the brush 2 will not loosen during operation. The screw connection method also facilitates the removal and installation of the brush 2. Among them, the locking member is usually a screw of appropriate size. In other embodiments, the brush 2 may be detachably connected to the mounting bracket 1 by a snap connection, or may be detachably connected to the mounting bracket 1 by a sliding locking mechanism.

[0037] Specifically, in one embodiment of the present invention, please refer to Figure 3 The mounting bracket 1 has two mounting portions 11 spaced apart from each other. The quick-assembly conductive slip ring 100 includes two locking members, each of which passes through one end of the mounting plate 21 and is threadedly connected to a mounting portion 11. The mounting bracket 1 has two spaced-apart mounting portions 11, providing more stable support, particularly when supporting heavy brushes 2 or maintaining stability in a vibrating environment. The two locking members secure the ends of the mounting portion 11, ensuring the brushes 2 are fixed in place in both directions and increasing the stability of the overall structure.

[0038] To facilitate installation of the brush 2, in one embodiment of the present invention, the mounting bracket 1 is formed with a positioning portion; the brush 2 is formed with a mating portion that cooperates with the positioning portion for positioning. The coordination of the mating portion and the positioning portion restricts the installation position of the brush 2, thereby ensuring accurate contact between the brush 2 and the slip ring 3, improving the quality and reliability of the electrical connection. Furthermore, when the brush 2 needs to be replaced or maintained, the positioning portion and the mating portion allow for quick removal and reinstallation, improving maintenance efficiency.

[0039] Specifically, in one embodiment of the present invention, please refer to Figures 1 to 3 The positioning portion is a positioning protrusion 12, and the mating portion is a positioning groove 23. Two positioning protrusions 12 are provided, one on each of the two mounting portions 11, and two corresponding positioning grooves 23 are also provided. The positioning protrusions 12 and the positioning grooves 23 ensure that the brush 2 is precisely aligned with the mounting bracket 1 during installation, which helps maintain stable contact between the brush 2 and the slip ring 3. In other embodiments, the positioning portion may be a positioning groove 23, the mating portion may be a positioning protrusion 12, or other positioning methods may be used.

[0040] Further, in one embodiment of the present invention, please refer to Figures 1 to 3 The quick-assembly conductive slip ring 100 also includes a limiting protrusion 4 provided on the mounting bracket 1. The limiting protrusion 4, the brush 2 and the mounting bracket 1 together form a receiving groove, and part of the structure of the slip ring 3 is inserted into the receiving groove. The limiting protrusion 4 is "C"-shaped or "U"-shaped, etc., that is, the limiting protrusion 4 has a gap, and the two mounting parts 11 of the mounting bracket 1 are respectively provided at the opposite ends of the gap. The mounting plate 21 of the brush 2 can close the gap after installation, and at the same time, the multiple brush filaments 22 of the brush 2 can enter the receiving groove through the gap to abut against the slip ring 3. That is, the contact points of the brush 2 and the slip ring 3 are all in the receiving groove. In this way, the noise generated by the brush 2 during the rotation of the slip ring 3 will be partially absorbed by the limiting protrusion 4 and then transmitted out, which greatly reduces the noise. In addition, a circular hole is provided at the bottom of the receiving groove (i.e., part of the structure of the mounting bracket 1) which passes through the mounting bracket 1, so that other components can contact the slip ring 3 through the circular hole when necessary, and the aperture of the circular hole is smaller than the outer diameter of the slip ring 3, so that the slip ring 3 can be prevented from passing through the circular hole.

[0041] Furthermore, in one embodiment of the present invention, please refer to Figures 1 to 3The quick-assembly conductive slip ring 100 also includes a dust cover 5, which covers the receiving slot and has a through-hole formed in the dust cover 5. Part of the structure of the slip ring 3 is inserted through the through-hole into the receiving slot. The dust cover 5 prevents dust and other contaminants from entering the receiving slot, reducing wear between the brushes 2 and the slip ring 3, helping to extend the service life of the slip ring 3 and brushes 2. It also prevents contaminants from affecting the electrical connection, maintaining the stability and accuracy of signal transmission. The dust cover 5 is detachably connected to the mounting bracket 1 by screws, facilitating installation and removal.

[0042] It is understandable that the structural design of the slip ring 3 itself may not be convenient for connection with other electrical structures. Therefore, in one embodiment of the present invention, please refer to Figure 2 The quick-assembly conductive slip ring 100 also includes an adapter ring 6, which is mounted on the end of the slip ring 3 away from the mounting bracket 1. The adapter ring 6 serves as an electrical connection medium, facilitating electrical connection at the end of the slip ring 3 away from the mounting bracket 1 and increasing system flexibility. The adapter ring 6 can be designed to meet different application requirements. For example, it can be designed with a specific interface to meet specific electrical or mechanical connection requirements.

[0043] Specifically, in one embodiment of the present invention, please refer to Figure 1 The slip ring 3 has a plurality of first through holes 31 formed in a circular array at the end of the slip ring 3 away from the mounting bracket 1. The adapter ring 6 has a plurality of second through holes 61, each of which communicates with a first through hole 31. This interconnected design of the first through holes 31 and the second through holes 61 allows for efficient transmission of electrical signals or power, improving signal transmission efficiency.

[0044] In order to facilitate transportation, in one embodiment of the present utility model, please refer to Figure 2 and Figure 3 The quick-assembly conductive slip ring 100 also includes a protective cover 7, which is screwed to the dust cover 5 and the slip ring 3. Since the dust cover 5 is connected to the mounting bracket 1, the position of the slip ring 3 relative to the mounting bracket 1 is fixed. This prevents the slip ring 3 from shaking during transportation, improving transportation safety. The protective cover 7 can be removed during installation.

[0045] The present invention further provides a motor device, which includes the quick-assembly conductive slip ring 100. The specific structure of the quick-assembly conductive slip ring 100 refers to the above-mentioned embodiment. Since the present motor device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here.

[0046] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
