[0038] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0039] Please refer to Figures 1-6This embodiment provides a generator carbon brush bracket 200, which includes a frame 210, a clamping assembly 220, and a movable assembly 230.

[0040] The frame 210 is used to accommodate carbon brushes, and the frame 210 is provided with a first sliding groove 211;

[0041] The clamping assembly 220 includes a clamping seat 221, a first elastic member 222, and a clamping block 223; the clamping seat 221 is slidably engaged with the first sliding groove 211; the clamping block 223 is slidably connected to the clamping seat 221, the first elastic member 222 is connected to the clamping seat 221 and abuts against the clamping block 223, and the first elastic member 222 is used to make the clamping block 223 have a tendency to slide toward the carbon brush;

[0042] The movable component 230 is movably connected to the frame 210. The movable component 230 is used to drive the clamping block 223 to overcome the elastic force of the first elastic element 222 and move in a direction away from the carbon brush.

[0043] Please refer to Figures 1-6 The working principle of the generator carbon brush bracket 200 is as follows:

[0044] The generator carbon brush holder 200 includes a frame 210, a clamping assembly 220, and a movable assembly 230; wherein, the frame 210 is used to accommodate the carbon brush, and the carbon brush located in the frame 210 is held by the clamping block 223, thereby maintaining the installation stability of the carbon brush in the frame 210.

[0045] When it is necessary to remove the carbon brush, since the clamping seat 221 is slidably engaged with the first sliding groove 211; the clamping block 223 is slidably connected to the clamping seat 221; the first elastic member 222 is connected to the clamping seat 221 and abuts against the clamping block 223; the first elastic member 222 is used to make the clamping block 223 have a tendency to slide towards the carbon brush; therefore, by applying an external force to the movable component 230, the clamping block 223 is driven to overcome the elastic force of the first elastic member 222 and move in the direction away from the carbon brush, so that the clamping block 223 can disengage from the carbon brush, thereby eliminating the clamping effect of the carbon brush. Thus, the carbon brush can be easily removed or inserted into the frame 210.

[0046] Therefore, the generator carbon brush bracket 200 has a simple structure, is easy to use, and facilitates the replacement of carbon brushes, thereby improving the installation and maintenance efficiency of carbon brushes.

[0047] Further, please refer to Figures 1-6In this embodiment, to improve the stability of the carbon brush clamping when setting the clamping component 220, the generator carbon brush bracket 200 may include two clamping components 220. Therefore, in order to install the two clamping components 220, the frame 210 is provided with two first sliding grooves 211, the two first sliding grooves 211 are arranged in parallel, and the clamping seats 221 of the two clamping components 220 correspond to and slide with the two first sliding grooves 211 respectively.

[0048] Further, please refer to Figures 1-6 Based on the above structural configuration, when using the configuration of two clamping components 220, the clamping blocks 223 of the two clamping components 220 need to be moved when removing or inserting the carbon brush. Therefore, in this embodiment, the frame 210 is provided with a second sliding groove 212, which is located between two first sliding grooves 211, and the first sliding grooves 211 and the second sliding groove 212 are parallel. The movable component 230 includes a first slider 231, a second slider 232, a limiting block 233, a movable rod 234, two push rods 235, and two pull rods 236.

[0049] Both the first slider 231 and the second slider 232 are slidably connected to the second slide groove 212. The limiting block 233 is housed in the second slide groove 212 and is used to abut against the second slider 232 to restrict the movement of the second slider 232. The movable rod 234 is connected to the first slider 231. Both push rods 235 are hinged to the second slider 232. Both ends of each pull rod 236 are respectively connected to one end of the movable rod 234 and the push rod 235. The end of each push rod 235 facing away from the second slider 232 is connected to a clamping block 223.

[0050] The movable rod 234 is used to move relative to the frame 210 under the action of external force, and drives the push rod 235 and the second slider 232 to move along the second slide groove 212 through the pull rod 236. When the second slider 232 abuts against the limiting block 233, it drives the push rod 235 to rotate relative to the second slider 232, so as to drive the clamping block 223 to overcome the elastic force of the first elastic member 222 and move in the direction away from the carbon brush.

[0051] With the above structural arrangement, when it is necessary to remove or insert carbon brushes, the clamping block 223 needs to move away from the carbon brush housed in the frame 210. Therefore, an external force can be applied to the movable rod 234. Since the movable rod 234 is connected to the first slider 231, the external force can drive the movable rod 234 to move relative to the frame 210 along the first slide groove 211. At this time, the direction of movement of the movable rod 234 is the direction in which the frame 210 removes the carbon brush. At the same time, since both ends of each pull rod 236 are respectively connected to one end of the movable rod 234 and the push rod 235; and the end of each push rod 235 away from the second slider 232 is connected to a... The clamping block 223 is connected, and both push rods 235 are hinged to the second slider 232; therefore, the movement of the movable rod 234 will drive the pull rods 236 located at both ends of the movable rod 234 to move, and the movement of the pull rods 236 will drive the push rods 235 connected to them to move; as the movable rod 234 continues to move in the same direction, when the second slider 232 abuts against the limiting block 233, since the movement of the second slider 232 is restricted, and both push rods 235 are hinged to the second slider 232, the continuous movement of the movable rod 234 in the same direction will drive the push rods 235 connected to it to rotate relative to the second slider 232 through the two pull rods 236;

[0052] Since the end of each push rod 235 away from the second slider 232 is connected to a clamping block 223, the rotation of each push rod 235 can drive the clamping block 223 connected to it to slide relative to the corresponding clamping seat 221, thereby causing the clamping block 223 to disengage from the carbon brush housed in the frame 210, so as to facilitate the removal of the carbon brush or the insertion of the carbon brush into the frame 210.

[0053] As the two push rods 235 move toward the limiting block 233 under the action of the movable rod 234, to prevent the external force applied by the pull rod 236 to the push rods 235 from causing them to rotate relative to the second slider 232, the movable assembly 230 also includes a second elastic element 237. The second elastic element 237 is connected to the two push rods 235 and is used to make the push rods 235 tend to rotate toward the direction away from the limiting block 233 and drive the clamping block 223 toward the carbon brush. Thus, with this arrangement, as the two push rods 235 move toward the limiting block 233 under the action of the movable rod 234, the elastic force of the second elastic element 237 restricts the rotation of the push rods 235 relative to the second slider 232. Similarly, when the second slider 232 abuts against the limiting block 233, the two push rods 235 overcome the elastic force of the second elastic element 237 under the action of the pull rod 236 and rotate relative to the second slider 232. In this design, the second elastic element 237 can be an M-type spring. Therefore, by providing the second elastic element 237, damage to the pulling force of the movable rod 234 of the two push rods 235 due to excessive tension can be avoided.

[0054] Further, please refer to Figures 1-6 In this embodiment, the generator carbon brush bracket 200 further includes a reset component 240, which is connected to the frame 210 and the clamping seat 221. The reset component 240 is used to make the clamping seat 221 have a tendency to move in the direction away from the limiting block 233.

[0055] Therefore, when the movable component 230 moves the clamping component 220 under the action of external force to remove or insert the carbon brush, the reset component 240 enables the clamping seat 221 to move away from the limiting block 233, thereby causing the two push rods 235 to return to their original positions. The clamping blocks 223 of the two clamping components 220 then return to their initial positions under the restoring force of the first elastic element 222 and the second elastic element 237, i.e., the clamping components 220 return to their original positions. At this time, the clamping blocks 223 clamp the carbon brush, and the reset component 240 also generates a downward restoring force, pressing the carbon brush into contact with the generator slip ring.

[0056] When setting the reset assembly 240, the reset assembly 240 includes a third elastic element 241 and a spiral spring 242; the spiral spring 242 is connected to the frame 210, and the third elastic element 241 connects the spiral spring 242 to the clamping seat 221. With this setting, the restoring force applied by the reset assembly 240 to the clamping assembly 220 can be adjusted by adjusting the spiral spring 242. Specifically, in this embodiment, the reset assembly 240 also includes a rotating shaft 243, which is rotatably connected to the frame 210, and the spiral spring 242 is wound around the rotating shaft 243. Thus, by adjusting the amount of winding of the spiral spring 242, the elastic force of the spiral spring 242 can be adjusted.

[0057] Further, please refer to Figures 1-6 In this embodiment, the inner wall of the frame 210 is also provided with a potential hole 213, and the generator carbon brush bracket 200 also includes a sliding potentiometer 250 and a fourth elastic member 260; the sliding potentiometer 250 and the fourth elastic member 260 are both housed in the potential hole 213, and the fourth elastic member 260 is used to make the sliding potentiometer 250 have a tendency to move toward the carbon brush.

[0058] It should be noted that before installing the carbon brush, the sliding potentiometer 250 needs to be "zeroed". During the installation and use of the carbon brush, the carbon brush contacts the sliding potentiometer 250, causing it to rotate and generate different resistance values ​​to form a linear electrical signal, which is then used to measure the carbon brush usage (the rotation stroke is determined according to the length of the carbon brush). The rotating potentiometer is a circular, non-fixed type, and the contact surface with the carbon brush is less than half of its circumference. To prevent insufficient contact force, a fourth elastic element 260 is installed at the rear of the potentiometer.

[0059] In addition, the generator carbon brush holder 200 also includes a contact switch 270 and a fifth elastic element 280; both the contact switch 270 and the fifth elastic element 280 are connected to the frame 210, and the fifth elastic element 280 is used to give the contact switch 270 a tendency to move towards the clamping assembly 220; the contact switch 270 is used to abut against the clamping assembly 220. It should be noted that during daily use, due to wear, the carbon brush will slowly slide downwards relying on the restoring force of the reset assembly 240; when the carbon brush wears to a certain length, the clamping seat 221 of the clamping assembly 220 will touch the contact switches on both sides, reminding the user to replace the carbon brush. The fifth elastic element 280 prevents the carbon brush from failing to contact the generator slip rings due to untimely replacement, effectively creating a margin of safety for the carbon brush.

[0060] Please refer to Figures 1-6In this embodiment, when connecting the movable rod 234 and the pull rod 236, and when connecting the pull rod 236 and the push rod 235, the connection is made by hinge. In addition, when removing the carbon brush, in this embodiment, the movable rod 234 moves upward to disengage the clamping block 223 from the carbon brush. Therefore, in this embodiment, the limiting block 233 is located above the second slider 232. Similarly, in this embodiment, the movable rod 234 moves downward to abut the clamping block 223 against the carbon brush. Therefore, the reset component 240, the sliding potentiometer, and the contact switch 270 are all located below the clamping seat 221.

[0061] In summary, please refer to the following: Figures 1-6 The generator carbon brush bracket 200 facilitates carbon brush replacement, enables remote monitoring of carbon brush usage, and allows adjustment of the spring force of the reset component 240 during carbon brush use, thereby reducing carbon brush wear, extending carbon brush lifespan, and reducing maintenance frequency.

[0062] Based on the above, please refer to Figures 1-6 The present invention provides a generator, the generator including a generator carbon brush holder 200 as described in any of the foregoing embodiments; the carbon brush is housed in a frame 210, and two clamping blocks 223 are used to clamp the carbon brush.

[0063] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
