Description

Technical Field

[0001] This utility model relates to the field of slip rings, and in particular to a modular and detachable slip ring device. Background Technology

[0002] A slip ring, also known as a conductive slip ring, rotary electrical interface, or slip ring, is an important device used to transmit electrical signals and power between rotating and stationary components. It is widely used in various fields that require rotational transmission, such as aerospace, robotics, medical equipment, security monitoring, and automated production lines. The slip ring achieves continuous transmission of electrical signals and power during rotation through the contact between its internal conductive ring and brush.

[0003] Traditional slip ring designs often employ an integral structure, integrating all components, including the conductive ring, brush, and housing, into a single, inseparable unit. While this design satisfies the requirements for rotational transmission to some extent, it also has several drawbacks. For instance, the integral structure makes maintenance, replacement of damaged parts, and performance upgrades extremely difficult. If any component in the slip ring fails, the entire slip ring often needs to be replaced, which not only increases maintenance costs but also prolongs repair time.

[0004] In addition, after prolonged use, traditional slip rings can experience problems such as increased contact resistance and decreased signal transmission quality due to friction and wear between the brush and the conductive ring. These problems not only affect the normal operation of the equipment but also shorten the service life of the slip ring. Utility Model Content

[0005] To address the problem that the integral structure of existing slip rings makes maintenance, replacement of damaged parts, and performance upgrades extremely difficult, and that once a component in the slip ring fails, the entire slip ring often needs to be replaced, this invention provides a modular and detachable slip ring device.

[0006] The modular and detachable slip ring device provided by this utility model adopts the following technical solution:

[0007] A modular and detachable slip ring device includes a first housing and a second housing, which are locked together by a locking module; brush units are respectively installed inside the first housing and the second housing by locking mechanisms; a rotor module is disposed between the two sets of brush units; the rotor module is rotatably connected to the first housing and the second housing by bearings.

[0008] Furthermore, the locking module includes a locking block, a plug, a locking ring, a locking hole, and a locking bolt. The locking block is integrally formed on the outer wall of the second housing; the plug is integrally formed on the bottom of the locking block; the locking ring is integrally formed on the outer wall of the first housing corresponding to the locking block position; a locking hole is formed inside the locking ring; threaded holes are formed inside the locking ring and the plug; a locking bolt for connecting the plug and the locking ring is connected in the threaded hole.

[0009] Furthermore, the outer wall of the brush unit is bolted with several brush filaments for cooperating with the rotor module;

[0010] Furthermore, the locking mechanism includes a limiting block, a positioning block, a sliding rod, and a spring; limiting blocks are welded to the inner walls of the first housing and the second housing respectively; positioning blocks are provided on the inner walls of the first housing and the second housing on the side opposite to the brush unit; a sliding rod is welded inside the first housing and the second housing; the positioning block is slidably connected to the outer wall of the sliding rod; a spring is welded between the positioning block and the first housing and the second housing; the spring is sleeved on the outer wall of the sliding rod.

[0011] Furthermore, the tops of both the positioning block and the limiting block are set as inclined surfaces; a lever is attached to the inclined surface of the positioning block; the lever is made of rubber.

[0012] Furthermore, the brush unit has a positioning hole inside; the bottom of the limiting block is integrally formed with a limiting protrusion that matches the positioning hole.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] This invention achieves the independence and detachability of each component by modularizing the rotor module, brush unit, first housing, and second housing. This makes it more convenient and faster to maintain, replace damaged parts, and upgrade the performance of the slip ring. Users can replace or upgrade individual components according to their actual needs without replacing the entire slip ring. The design of the locking module and locking mechanism ensures a firm lock between the first and second housings and stable fixation of the brush unit within the housing. Furthermore, the brush unit can be easily pulled out by moving the positioning block to release the restriction on the brush unit. This design allows users to quickly replace damaged brush filaments, reducing maintenance costs and time. Attached Figure Description

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described in detail below:

[0023] This utility model discloses a modular and detachable slip ring device, such as... Figure 1 , 2 As shown in Figure 3, the device includes a first housing 1 and a second housing 2, which are locked together by a locking module 3. Brush units 5 are installed inside the first housing 1 and the second housing 2 respectively via locking mechanisms. A rotor module 4 is positioned between the two sets of brush units 5. The rotor module 4 is rotatably connected to the first housing 1 and the second housing 2 via bearings 7. In this embodiment, by modularizing the rotor module 4, brush units 5, first housing 1, and second housing 2, the independence and detachability of each component are achieved, facilitating maintenance, replacement of damaged components, and performance upgrades. The rotor module 4 is installed between the first housing 1 and the second housing 2 and rotatably connected to both via bearings 7, allowing the rotor module 4 to rotate freely. The brush units 5 are respectively installed inside the first housing 1 and the second housing 2 and fixed by locking mechanisms. The first housing 1 and the second housing 2 are locked together by the locking module 3 to form a complete slip ring device housing. The modular design improves the flexibility and maintainability of the device, facilitates component replacement or upgrades as needed, and reduces maintenance costs and time.

[0024] like Figure 3 , 4As shown in Figure 5, the locking module 3 includes a locking block 31, an insert block 32, a locking ring 33, a locking hole 34, and a locking bolt 35. The locking block 31 is integrally formed on the outer wall of the second housing 2; the insert block 32 is integrally formed on the bottom of the locking block 31; the locking ring 33 is integrally formed on the outer wall of the first housing 1 at the position corresponding to the locking block 31; the locking hole 34 is provided inside the locking ring 33; threaded holes are provided inside the locking ring 33 and the insert block 32; a locking bolt 35 for connecting the insert block 32 and the locking ring 33 is connected in the threaded hole; in this embodiment, the locking module 3 realizes the first housing The first housing 1 and the second housing 2 are securely locked together. A locking block 31 and an insert block 32, integrally formed on the outer wall of the second housing 2, engage with a locking ring 33 on the outer wall of the first housing 1. The insert block 32 is inserted into the locking ring 33, and the two are fastened together by a connecting bolt in a locking hole 34 and a threaded hole. When disassembly is required, simply remove the locking bolt 35 to pull the insert block 32 out of the locking ring 33, thus separating the first housing 1 and the second housing 2. This design provides a simple and effective locking method; facilitates disassembly and assembly, reduces maintenance difficulty; and enhances the stability and durability of the device.

[0025] like Figure 3 As shown, the outer wall of the brush unit 5 is bolted with several brush filaments 51 for cooperating with the rotor module 4. In this embodiment, these brush filaments 51 cooperate with the rotor module 4 to realize current transmission. The brush filaments 51 are fixed to the outer wall of the brush unit 5 by bolts. When the rotor module 4 rotates, the brush filaments 51 contact the rotor module 4 to realize current transmission. If the brush filaments 51 are damaged, they can be replaced by removing the bolts. This design provides a reliable current transmission method and facilitates the replacement of damaged brush filaments 51, reducing maintenance costs and improving the reliability and service life of the device.

[0026] like Figure 3 , 4As shown in Figure 5, the locking mechanism includes a limiting block 6, a positioning block 62, a sliding rod 64, and a spring 65. Limiting blocks 6 are welded to the inner walls of the first housing 1 and the second housing 2 respectively. Positioning blocks 62 are provided on the inner walls of the first housing 1 and the second housing 2 on the side opposite to the brush unit 5. Sliding rods 64 are welded inside the first housing 1 and the second housing 2. Positioning blocks 62 are slidably connected to the outer wall of the sliding rod 64. A spring 65 is welded between the positioning block 62 and the first housing 1 and the second housing 2. The spring 65 is sleeved on the outer wall of the sliding rod 64. A positioning hole 52 is provided inside the brush unit 5. A limiting protrusion 61 that mates with the positioning hole 52 is integrally formed at the bottom of the limiting block 6. In this embodiment, the brush unit 5 is fixed inside the first housing 1 and the second housing 2. The limiting block 6 is welded to the first housing 1 and the second housing 2. On the inner wall, the positioning block 62 is slidably connected to the slide rod 64 and connected to the first housing 1 and the second housing 2 via the spring 65. When the brush unit 5 is installed, the limiting protrusion 61 of the limiting block 6 is inserted into the positioning hole 52 of the brush unit 5, and at the same time, the inclined surface of the positioning block 62 is pushed by the brush unit 5, compressing the spring 65. After the brush unit 5 is fully installed, the elastic force of the spring 65 causes the positioning block 62 to return to its original position, firmly fixing the brush unit 5 inside the first housing 1 and the second housing 2. If it is necessary to remove the brush unit 5, the lever 63 on the positioning block 62 can be moved to compress the spring 65 and release the restriction on the brush unit 5, and then the brush unit 5 can be pulled out. This design provides a simple and effective fixing method; facilitates the installation and removal of the brush unit 5; and enhances the stability and reliability of the device.

[0027] like Figure 4 , 5 As shown in Figure 6, the tops of both the positioning block 62 and the limiting block 6 are set as inclined surfaces; a lever 63 is attached to the inclined surface of the positioning block 62; the lever 63 is made of rubber; in this embodiment, the tops of both the positioning block 62 and the limiting block 6 are set as inclined surfaces, which facilitates the installation and removal of the brush unit 5; at the same time, the design of the lever 63 further improves the convenience of operation; when installing the brush unit 5, the brush unit 5 pushes the inclined surface of the positioning block 62, causing the positioning block 62 to slide along the slide rod 64 and compress the spring 65; when the brush unit 5 is fully installed, the elastic force of the spring 65 causes the positioning block 62 to return to its original position, and the inclined surface forms a stable contact with the brush unit 5; by moving the positioning block 62, the restriction on the brush unit 5 is released, which facilitates disassembly and simplifies the installation and disassembly process; improves the convenience of operation; and enhances the reliability and durability of the device.

[0028] The implementation principle of this utility model embodiment is as follows:

[0029] This utility model adopts a modular design for the rotor module 4, brush unit 5, and housing, allowing each part to be designed and disassembled individually. By moving the positioning block 62 and compressing the spring 65, the positioning block 62 is released from its restriction on the brush unit 5, and then the brush unit 5 can be pulled out from the bottom of the limiting block 6 and contact the limiting protrusion 61 restricting the positioning hole 52. The first housing and the second housing can also be disassembled by simply removing the locking bolt 35 and pulling the insert 32 out of the locking ring 33. In addition, the brush wires 51 are connected by bolts and can also be disassembled individually after damage.
