Description

Technical Field

[0001] This utility model relates to the field of regulator technology, specifically to a carbon brush protective cover for an automotive regulator. Background Technology

[0002] A carbon brush protector, as the name suggests, is a component that protects the carbon brushes. It is assembled on the regulator of an automotive alternator. Its main function is to prevent foreign objects such as mud, water, and dust from entering the slip rings and brush chamber during alternator operation, which could cause problems such as short circuits, sticking, abnormal noise, and abnormal wear of the carbon brushes.

[0003] All the drawbacks of existing technology:

[0004] 1. Insufficient sealing: Most existing carbon brush protectors and regulators are clearance fits, resulting in varying degrees of gaps after assembly. Water, oil, and other liquids can then enter the protector and brush chamber through these gaps, causing problems such as short circuits in the carbon brushes.

[0005] 2. Insufficient protection: Due to the snap-fit ​​structure and molding process, existing carbon brush protective covers have gaps that cannot completely protect the carbon brush and brush head. This allows foreign objects such as mud and dust to enter the inside of the protective cover and brush cavity through the gaps, causing problems such as carbon brush jamming, abnormal noise, and abnormal wear.

[0006] 3. Low disassembly capability: The existing carbon brush protector has clips on both the left and right sides. After the clips are locked with the adjuster, they are inserted deep into the bottom of the adjuster's groove, making them inaccessible to human hands and difficult to disassemble, which is not conducive to rework.

[0029] The present invention will now be described in further detail in conjunction with the full text.

[0030] Combined with appendix Figures 1-3 A carbon brush protector for an automotive regulator includes a regulator housing 1 and a carbon brush protector body 2 that is snapped onto the regulator housing 1. The buckles on the left and right sides are replaced with buckles at the rear end of the protector to avoid gaps in the protector. This protects the carbon brush and the entire brush head, allowing foreign objects such as mud and water to pass directly over the carbon brush and slip ring along the top surface of the protector, preventing them from entering the interior of the protector and improving the product's protective performance.

[0031] A sealing ring 8 is installed between the carbon brush protector body 2 and the regulator housing 1 for sealing.

[0032] A limiting device for limiting is installed between the carbon brush protector body 2 and the regulator housing 1.

[0033] In specific implementation of this utility model, such as Figure 2and Figure 3 As shown. The limiting device includes a positioning post 3 positioned relative to the carbon brush protector body 2. A limiting rib 4 is installed opposite to the outer side of the positioning post 3. A first groove 5 and a second groove 6 are formed on the carbon brush protector body 2, and a U-shaped rib 14 is formed between the first groove 5 and the second groove 6. A limiting groove 15 that cooperates with the positioning post 3 and a sealing groove 7 that cooperates with the U-shaped rib 14 are formed on the regulator housing 1. The first groove 5, the second groove 6, the first rib 12 and the second rib 13 form a multi-level tortuous structure to prevent liquids such as water and oil from entering the interior of the protector and the brush cavity, thereby improving the sealing performance of the product.

[0034] In specific implementation of this utility model, such as Figure 2 and Figure 3 As shown, a first rib 12 and a second rib 13 are formed between the limiting groove 15 and the sealing groove 7. The first rib 12 can be installed in the first groove 5, and the second rib 13 can be installed in the second groove 6. The sealing ring 8 is installed in the sealing groove 7, and the U-shaped rib 14 is inserted into the sealing groove 7 to apply pressure to the sealing ring 8, forming a sealing structure to prevent liquids such as water and oil from entering the interior of the protective cover and the brush cavity, thereby improving the product's sealing performance.

[0035] A U-shaped connecting rib 16 is installed on one side of the second groove 6, and a snap-fit ​​protrusion 9 is installed on the outer side of the U-shaped connecting rib 16. A limiting protrusion 10 is installed on the regulator housing 1 to cooperate with the snap-fit ​​protrusion 9.

[0036] In specific implementation of this utility model, such as Figure 2 and Figure 3 As shown. The two buckle protrusions 9 are connected to the protective cover by a U-shaped connecting rib 16 to form a whole. The buckles and the carbon brush protective cover body 2 are separated by the second groove 6, forming an inverted U-shaped structure. When the upper U-shaped connecting rib 16 is pressed, the two buckle protrusions 9 move back, and the protective cover can be easily removed for rework. The carbon brush protective cover body 2 is made of plastic.

[0037] The carbon brush protective cover body 2 has a reinforcing rib 11 installed inside.

[0038] The working principle of this utility model:

[0039] The carbon brush protector has two positioning posts with limiting ribs. The positioning posts mate with the positioning holes on the regulator to ensure the carbon brush protector is properly assembled. An O-ring is fitted into the sealing groove of the regulator. The carbon brush protector has U-shaped ribs that compress the O-ring after assembly onto the regulator. The limiting ribs on the positioning posts prevent the U-shaped ribs from expanding outwards and failing to compress the O-ring. Then, the regulator and carbon brush protector are assembled onto the end cap. A sealing gasket is placed between the end cap and the regulator. The regulator and carbon brush protector compress the sealing gasket, forming a sealed structure that prevents water, oil, and other liquids from entering the protector and brush chamber, improving the product's sealing performance.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
