Description

Technical Field

[0001] This application relates to the field of vehicle generator technology, and in particular to a generator carbon brush chamber protection component, a generator, and a vehicle. Background Technology

[0002] Pickup trucks and SUVs are used in environments with mud and sand. If the vehicle does not have protection around the generator, mud and sand will enter the generator, causing the carbon brushes to stick and ultimately preventing the generator from generating electricity. The generator cannot be made into a completely sealed design because the regulator chip and heat sink need to dissipate heat. A completely sealed design would cause the regulator and diodes to malfunction, ultimately preventing the generator from generating electricity.

[0003] The current generator design is not sufficiently protective, and mud and sand can easily enter the generator protective cover through the generator gaps. Due to the poor fluidity and high viscosity of mud, if the mud and sand content is high, after entering the carbon brush slip ring structure, the mud and sand will deposit at high temperature and invade the root of the regulator carbon brush, causing the carbon brush to stick. After the carbon brush sticks, it will have poor contact with the slip ring, the excitation circuit will be disconnected, and the generator will not generate electricity. Utility Model Content

[0004] This application aims to address the problem of insufficient protection in the design of generators in related technologies, which allows mud and sand to easily enter the generator protective cover along the generator gaps. Therefore, this utility model proposes a generator carbon brush chamber protection component, a generator, and a vehicle.

[0005] To achieve the above objectives, embodiments of this application provide a generator carbon brush chamber protection assembly, comprising:

[0006] A centrifugal ring, configured to be fitted onto the circumferential surface of the generator shaft near the carbon brush chamber, the centrifugal ring comprising:

[0007] A first stop portion is used to be sleeved on the surface of the rotating shaft;

[0008] An extension portion is disposed on the circumferential periphery of the first stop portion;

[0009] The second stop is disposed on the circumference of the extension away from the first stop, wherein the first stop, the extension and the second stop are integrally formed and form a continuous multi-segment bend.

[0010] In some possible embodiments, a first bend is provided between the first stop and the extension, the first bend protruding from the surface of the extension.

[0011] In some possible embodiments, a second bend is provided between the extension and the second stop.

[0012] In some possible embodiments, the first stop portion and the second stop portion are annular in shape.

[0013] In some possible embodiments, the first stop and the second stop are arranged along a common central axis.

[0014] In some possible embodiments, a mounting shim is also included for mounting and positioning the centrifugal ring. The mounting shim is provided with a limiting through hole, in which the centrifugal ring is embedded.

[0015] In some possible embodiments, the surface of the mounting pad is provided with a plurality of positioning holes near the limiting through hole, and the surface of the extension is provided with positioning pins, the positioning pins being interference-fitted with the positioning holes.

[0016] Secondly, embodiments of this application also provide a generator, the generator including the generator carbon brush chamber protection assembly described in any of the above embodiments.

[0017] In some possible embodiments, the generator further includes a rotating shaft, a slip ring fixedly disposed on the rotating shaft, a carbon brush chamber surrounding the slip ring, a carbon brush disposed in the carbon brush chamber and slidably sleeved on the slip ring, and a receiving groove disposed on one side of the carbon brush chamber, wherein the protective component is disposed in the receiving groove and forms a labyrinth channel with one end face of the carbon brush chamber.

[0018] Thirdly, embodiments of this application also provide a vehicle including the generator described in any of the above embodiments.

[0019] Compared with the prior art, the technical solutions provided by the above embodiments of this application have at least the following beneficial effects:

[0020] This application provides a generator carbon brush chamber protection component, a generator, and a vehicle. The generator carbon brush chamber protection component includes a centrifugal ring and a mounting gasket. The mounting gasket facilitates the installation and positioning of the centrifugal ring. The centrifugal ring has multiple stop portions and multiple bend portions. The stop portions and bend portions give the centrifugal ring an irregular surface, forming a labyrinth structure with the protective cover of the carbon brush chamber. The labyrinth structure can prevent mud, sand, and splashed water from entering the carbon brush chamber, thereby effectively protecting the carbon brushes. At the same time, the centrifugal ring does not completely seal the carbon brush chamber, thus not affecting the heat dissipation of related components (such as regulator chips and heat sinks). Furthermore, the centrifugal ring and mounting gasket are placed within the original space gap of the generator, thus eliminating the need for major modifications to the generator structure and reducing manufacturing costs.

[0034] The embodiments of this application are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. It should be understood that the specific embodiments described herein are merely for explaining this application and are not intended to limit this application.

[0035] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. "Multiple" means at least two, that is, two or more; "multiple" means at least two, that is, two or more.

[0036] In this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist; for example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0039] Please see Figure 1 and Figure 2 This embodiment provides a generator 10, which includes a rotating shaft 11, a slip ring 13 fixedly disposed on the rotating shaft 11, a carbon brush chamber disposed around the slip ring 13, a carbon brush 14 disposed in the carbon brush chamber and slidably sleeved on the slip ring 13, and a receiving groove 12 disposed on one side of the carbon brush chamber. A protective component is disposed in the receiving groove 12 and forms a labyrinth channel with one end face of the carbon brush chamber.

[0040] It should be noted that, in this embodiment, apart from the protective component, the other structures are existing generator structures. For example, the receiving groove 12 formed between the left side of the carbon brush chamber (not marked in the figure) and the rotating shaft 11 is an existing generator structure. External mud and sand entering the generator protective cover mainly pass through the receiving groove 12. The protective component of this embodiment makes good use of this structure. Therefore, even if the protective component is added, there is no need to improve the existing generator structure. Thus, for the protective component proposed in this embodiment, when realizing the blocking effect of the generator against external mud and sand, there is no need to make major changes to the generator structure or add other devices to achieve this function, thus avoiding increased costs and investment.

[0041] Therefore, the structures such as the rotating shaft 11, slip ring 13, and carbon brush 14 inside the generator will not be described in detail here, but the generator carbon brush chamber protection components will be further described below in conjunction with several embodiments.

[0042] Please see Figures 3 to 6 The protective component includes a centrifugal ring 100, which is configured to be fitted onto the circumferential surface of the generator shaft near the carbon brush chamber. The centrifugal ring 100 is an integral structure, including a first stop portion 110 fitted onto the shaft surface, an extension portion 120 disposed on the circumferential periphery of the first stop portion 110, and a second stop portion 130 disposed on the circumferential periphery of the extension portion 120 away from the first stop portion 110. The first stop portion 110, the extension portion 120, and the second stop portion 130 are integrally formed and form a continuous multi-segment bend.

[0043] Optionally, a first bend 111 is provided between the first stop 110 and the extension 120. The first bend 111 protrudes from the surface of the extension 120. Specifically, the first bend 111 protrudes from the side away from the carbon brush chamber. The first bend 111 can make the centrifugal ring 100 more stable. The extension 120 is a flat surface. The first bend 111 makes the extension 120 and the first stop 110 perpendicular to each other.

[0044] Optionally, a second bend 121 is provided between the extension 120 and the second stop. Unlike the first bend 111, the second bend 121 is an inclined surface. The arrangement of the first bend 111 and the second bend 121 forms a labyrinth structure with the protective cover. The labyrinth structure can prevent splashing water and mud from entering the carbon brush chamber, thereby effectively protecting the carbon brush 14. At the same time, the arrangement of multiple bends facilitates the installation and positioning of the centrifugal ring 100.

[0045] Optionally, the first stop 110 and the second stop 130 are annular in shape. The first stop 110 and the second stop 130 are arranged along the same central axis. That is, the first stop 110 is sleeved on the surface of the rotating shaft 11 and fits against the outer surface of the rotating shaft. However, when the rotating shaft 11 rotates, the centrifugal ring 100 remains stationary. The second stop 130 does not completely seal the carbon brush chamber. It can effectively block mud and sand, and does not affect the heat dissipation of related components (such as regulator chips and heat sinks).

[0046] In some embodiments, the protective component may further include a mounting gasket 200 for mounting and positioning the centrifugal ring 100. The mounting gasket 200 is provided with a limiting through hole 210, and the centrifugal ring 100 is embedded in the limiting through hole 210. Specifically, the mounting gasket 200 includes a first surface 220, a second surface 230, and a third surface 240 disposed at the edge of the limiting through hole 210. The first surface 220, the second surface 230, and the third surface 240 are connected in sequence and continuously bent.

[0047] It should be noted that the structure formed by the sequential connection and continuous bending of the first surface 220, the second surface 230 and the third surface 240 fits into the outer surface of the first bent portion 111, the extension portion 120 and the second bent portion 121 of the centrifugal ring 100, thereby achieving the limiting installation of the centrifugal ring 100.

[0048] Please see Figure 7 A positioning hole 231 is provided on the second surface 230 of the mounting shim 200, and a positioning pin 140 is provided on the outer surface of the extension 120 of the centrifugal ring 100. The positioning pin 140 and the positioning hole 231 are interference-fitted to achieve positioning and fixing during the installation of the centrifugal ring 100. There can be two or more positioning pins 140 and positioning holes 231. The mounting shim 200 is installed on the side of the rotating shaft close to the bearing.

[0049] In the above embodiments, the generator carbon brush chamber protection assembly includes a centrifugal ring 100 and a mounting gasket 200. The mounting gasket 200 facilitates the installation and positioning of the centrifugal ring 100. The centrifugal ring 100 is provided with multiple stop portions and multiple bend portions. The stop portions and bend portions give the centrifugal ring 100 an irregular surface, forming a labyrinth structure with the protective cover of the carbon brush chamber. The labyrinth structure can prevent mud, sand, and splashed water from entering the carbon brush chamber, thereby effectively protecting the carbon brushes. At the same time, the centrifugal ring 100 does not completely seal the carbon brush chamber, thus not affecting the heat dissipation of related components (such as regulator chips and heat sinks). Furthermore, the centrifugal ring 100 and the mounting gasket 200 are located within the original space gap of the generator, thus eliminating the need for major modifications to the generator structure and reducing production costs.

[0050] In some embodiments, a vehicle is also provided, including the generator described in any of the above embodiments.

[0051] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model.
