Description

Technical Field

[0001] This utility model relates to the field of carbon brush components, and in particular to an early warning carbon brush component. Background Technology

[0002] Motor carbon brushes are components used in electric motors or generators, primarily for transmitting electrical electricity. They are typically made of carbon and other additives, providing a stable current transmission during motor operation. However, motor carbon brushes can experience severe wear during use.

[0003] Some existing carbon brushes, when in use, may wear out excessively and become unusable. Some of them cannot provide early warning, which leads to rotor wear and makes timely replacement difficult.

[0004] To address the aforementioned issues, this application proposes an early warning carbon brush assembly. Utility Model Content

[0005] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a warning-type carbon brush assembly. This utility model is equipped with an alarm mechanism to trigger an alarm after the carbon brush has been used, thereby reminding users to replace it in time and reducing the occurrence of damage.

[0006] (II) Technical Solution To solve the above problems, this utility model provides an early warning carbon brush assembly, including a guide shell, in which a carbon brush is slidably sleeved, and a mounting plate is fixedly connected to one end of the guide shell; The mounting plate is connected to the carbon brush via a stop and a compression spring; The carbon brush is equipped with an alarm mechanism that causes it to rotate due to gradual wear and tear, eventually coming into contact with the rotor.

[0007] Preferably, the alarm mechanism includes a rotating wheel, a rotating box, a siren, and an air guide plate. The rotating wheel is rotatably connected to the carbon brush via a rotating shaft. The rotating box is fixedly installed on the rotating wheel. An air inlet is provided on the outer periphery of the rotating box. The air guide plate is fixedly installed inside the rotating box. An air guide plate extends to the outside of the rotating box at each air inlet. The siren is located in the middle of the rotating box on the side away from the carbon brush.

[0008] Preferably, a rubber ring is fixedly fitted around the outer periphery of the wheel, and the rubber ring has anti-slip texture.

[0009] Preferably, the sounding element is a whistle or a mouthpiece.

[0010] Preferably, an air collecting ring is fixedly installed in the middle of the rotating box, and the air collecting ring is connected to the air duct formed between the air collecting ring and the air guide plate.

[0011] The above-mentioned technical solution of this utility model has the following beneficial technical effects: The mounting plate is connected to the motor stator. Under the action of the compression spring, the carbon brushes are always pressed against the rotor. As the carbon brushes wear down, the rollers move towards the rotor until they contact it. As the rotor rotates, the rollers rotate, which in turn rotates the rotating box and the air guide plate. This causes the air guide plate to pour air into the interior of the rotating box. The air inside the rotating box then enters the audible alarm, which serves as a warning that the carbon brushes are about to run out of power, thus reminding the user to replace them.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0017] like Figure 1-3 As shown, the present invention proposes an early warning carbon brush assembly, including a guide shell 1, a carbon brush 2 slidably sleeved inside the guide shell 1, and an mounting plate 3 fixedly connected to one end of the guide shell 1. The mounting plate 3 is connected to the carbon brush 2 via a stop block 5 and a compression spring 4; The carbon brush 2 is equipped with an alarm mechanism 6 that rotates due to the gradual wear and tear of the carbon brush 2 and its contact with the rotor.

[0018] In an optional embodiment, the alarm mechanism 6 includes a rotating wheel 61, a rotating box 62, a siren 63, and an air guide plate 64. The rotating wheel 61 is rotatably connected to the carbon brush 2 via a rotating shaft. The rotating box 62 is fixedly mounted on the rotating wheel 61. An air inlet is provided on the outer periphery of the rotating box 62. The air guide plate 64 is fixedly mounted inside the rotating box 62. One air guide plate 64 extends to the outside of the rotating box 62 at each air inlet. The siren 63 is located in the middle of the rotating box 62 on the side away from the carbon brush 2.

[0019] It should be noted that there are multiple air guide plates 64, and the multiple air guide plates 64 are set in pairs at the air inlet.

[0020] In an optional embodiment, a rubber ring is fixedly fitted around the outer periphery of the wheel 61, and the rubber ring has anti-slip texture.

[0021] It should be noted that the rubber ring is used to increase the stability of the transmission.

[0022] In an alternative embodiment, the sounding element 63 is a whistle or a mouthpiece.

[0023] It should be noted that when a whistle is selected, the air inlet of the whistle is fixedly connected to the rotating box 62; When using a blower nozzle, the blower nozzle is fixedly installed on the rotating box 62 and connected to the rotating box 62.

[0024] In an optional embodiment, an air collecting ring 65 is fixedly installed in the middle of the rotating box 62, and the air collecting ring 65 is connected to the air duct formed between the air collecting ring 65 and the air guide plate 64.

[0025] It should be noted that the gas collecting ring 65 collects the gas entering the rotating box 62 and sprays it out by the sounding element 63 to make a sound.

[0026] In this invention, the mounting plate 3 is connected to the motor stator. Under the action of the compression spring 4, the carbon brush 2 is always pressed against the rotor. As the carbon brush 2 wears down, the rotating wheel 61 moves towards the rotor until it contacts the rotor. As the rotor rotates, the rotating wheel 61 rotates. The rotation of the rotating wheel 61 causes the rotating box 62 and the air guide plate 64 to rotate, so that the air guide plate 64 pours gas into the interior of the rotating box 62. The gas entering the rotating box 62 enters the audible element 63, thus playing the role of sounding an alarm to warn that the carbon brush 2 is about to be exhausted, thereby reminding it to be replaced.

[0027] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
