Description

Technical Field

[0001] This application relates to the field of conductive carbon brush technology, and in particular to a grounding conductive carbon brush for a new energy vehicle motor. Background Technology

[0002] Currently, the main function of installing grounding conductive carbon brushes on the outer casing of new energy vehicle motors is to conduct static electricity or leakage current on the motor casing into the grounding system, thereby protecting the internal components of the motor, preventing static electricity accumulation and electromagnetic interference, and ensuring the safe operation and electromagnetic compatibility of the motor.

[0003] However, the existing grounding conductive carbon brushes for new energy vehicle motors have the following drawbacks: For example, the grounding conductive carbon brush is usually fixed to the mounting housing and then to the housing of the vehicle motor with bolts. However, the grounding conductive carbon brush will wear out after long-term use and needs to be replaced regularly. Therefore, in the existing technology, the entire carbon brush and mounting housing structure needs to be disassembled when replacing the carbon brush. The disassembly process is too cumbersome and therefore not convenient for replacing the carbon brush. Summary of the Invention

[0004] The purpose of this application is to enable the installation of grounding conductive carbon brushes on the motor housing, facilitating the periodic replacement of individual carbon brushes without the need to disassemble the carbon brushes and the housing as a whole.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a grounding conductive carbon brush for a new energy vehicle motor, comprising a mounting housing, a cover plate installed on the outer wall of the mounting housing, a retaining plate slidably connected inside the mounting housing, a carbon brush body slidably connected inside the mounting housing and the cover plate, a retaining groove opened inside the carbon brush body, the retaining plate slidably connected inside the retaining groove, a slider installed inside the mounting housing, a retaining rod slidably connected inside the slider, a second limiting hole opened inside the carbon brush body, the retaining rod slidably connected inside the second limiting hole, a first limiting hole opened inside the retaining plate, the retaining rod slidably connected inside the first limiting hole, a pull plate fixedly connected to the outer wall of the retaining rod, and a second spring sleeved on the outer wall of the retaining rod.

[0006] In a further preferred embodiment, one end of the second spring is fixedly connected to the inside of the pull plate, the other end of the second spring is fixedly connected to the inside of the slider, a wire is fixedly connected to the upper end of the carbon brush body, and a connecting block is fixedly connected to the upper end of the wire.

[0007] In a further preferred embodiment, the card plate has an insertion hole inside, the limiting hole and the connecting block are disposed inside the insertion hole, and the wire is movably connected between the mounting shell and the cover plate.

[0008] In a further preferred embodiment, the cover plate has a groove inside, and the slider is slidably connected inside the groove.

[0009] Further preferably, the upper surface of the card plate is provided with two springs, which are symmetrically arranged on both sides of the upper surface of the card plate and on both sides of the outer wall of the wire.

[0010] More preferably, one end of the spring is fixedly connected to the inside of the mounting housing, and the other end of the spring is fixedly connected to the inside of the card plate.

[0011] Further preferably, a support base is fixedly connected to the lower surface of the mounting housing, and the support base has mounting holes inside.

[0012] Preferably, the outer walls of the mounting housing and the cover plate are provided with hinges, one end of the hinges is fixedly connected to the outer wall of the mounting housing, the other end of the hinges is fixedly connected to the outer wall of the cover plate, and bolts are threadedly connected between the mounting housing and the cover plate.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] (1) Pull the pull plate outward to make the lever slide outward and disengage from the slot and the limiting hole. Then, after opening the cover plate, slide the carbon brush body downward so that the slot disengages from the plate after the carbon brush body moves down. Then the carbon brush body can be removed separately for replacement, thus achieving the effect of easy and quick replacement of the carbon brush body.

[0015] (2) During use, the carbon brush body is supported by the spring and the clamping plate to ensure that the lower end of the carbon brush body is always in contact with the motor housing. The connecting block is connected to the grounding system. During the operation of the motor, the motor housing may generate static electricity due to friction or electromagnetic induction. Through the contact between the carbon brush body and the motor housing and the connection to the grounding system, static electricity and leakage current are discharged, protecting the internal components of the motor, preventing current from accumulating on the motor housing, and extending the service life of the motor.

[0026] like Figure 1-5The grounding conductive carbon brush for a new energy vehicle motor shown includes a mounting housing 1. Its features include: a cover plate 2 installed on the outer wall of the mounting housing 1; a retaining plate 3 slidably connected inside the mounting housing 1; the retaining plate 3 consisting of a top plate and two symmetrical vertical plates symmetrically arranged on the lower surface of the top plate; a carbon brush body 4 slidably connected inside the mounting housing 1 and the cover plate 2; two retaining slots 401 symmetrically arranged inside the carbon brush body 4; the retaining plate 3 slidably connected inside the retaining slots 401; the two vertical plates at the lower end of the retaining plate 3 being engaged inside the retaining slots 401; a slider 5 installed inside the mounting housing 1; a retaining rod 501 slidably connected inside the slider 5; a second limiting hole 402 inside the carbon brush body 4; and the retaining rod 501 slidably connected inside the second limiting hole 402. The plate 3 has a limiting hole 301 inside, which is located in the vertical plate at the lower end of the plate 3. The locking rod 501 is slidably connected inside the limiting hole 301. The outer wall of the locking rod 501 is fixedly connected to the pull plate 502. The outer wall of the locking rod 501 is fitted with a spring 503. One end of the spring 503 is fixedly connected to the inside of the pull plate 502, and the other end of the spring 503 is fixedly connected to the inside of the slider 5. The spring 503 supports the slider 5 and the pull plate 502. The upper end of the carbon brush body 4 is fixedly connected to the wire 403. The upper end of the wire 403 is fixedly connected to the connecting block 404. The connecting block 404 is used to connect the grounding system. The plate 3 has an insertion hole 303 inside. The limiting hole 402 and the connecting block 404 are disposed inside the insertion hole 303. The wire 403 is movably connected between the mounting shell 1 and the cover plate 2.

[0027] The cover plate 2 has a groove 201 inside, and the slider 5 is slidably connected inside the groove 201. Two springs 302 are symmetrically arranged on both sides of the upper surface of the clamping plate 3, and on both sides of the outer wall of the wire 403. One end of each spring 302 is fixedly connected to the inside of the mounting housing 1, and the other end is fixedly connected to the inside of the clamping plate 3. The two springs 302 support the clamping plate 3, causing it to contact the carbon brush body 4, ensuring that the lower surface of the carbon brush body 4 is flush with the motor housing. A support base 101 is fixedly connected to the lower surface of the mounting housing 1. The support base 101 has a mounting hole 102 inside. The support base 101 and the mounting hole 102 facilitate the mounting housing 1 to be installed on the motor housing. The outer walls of the mounting housing 1 and the cover plate 2 are provided with hinges 6. One end of the hinge 6 is fixedly connected to the outer wall of the mounting housing 1, and the other end of the hinge 6 is fixedly connected to the outer wall of the cover plate 2. The hinge 6 allows the cover plate 2 to be rotated and opened. A bolt 7 is threadedly connected between the mounting housing 1 and the cover plate 2, and the mounting housing 1 and the cover plate 2 are fixedly connected by the bolt 7.

[0028] Working principle: During the manufacturing process of the carbon brush body 4, two symmetrical slots 401 are opened at the upper part of the carbon brush body 4, and two corresponding limiting holes 402 are opened. The upper end of the carbon brush body 4 is fixed with a wire 403, and a connecting block 404 is fixed at the upper end of the wire 403. The cover plate 2 is opened, and the wire 403 and the connecting block 404 are passed through the insertion hole 303. The vertical plate part at the lower end of the card plate 3 is locked inside the slot 401. The limiting hole 301 is aligned with the limiting hole 402. The cover plate 2 is rotated and closed, and the locking rod 501 passes through the limiting hole 402 and the limiting hole 301, so that the card plate 3 and the carbon brush body 4 are limited and fixed. The cover plate 2 and the mounting housing 1 are fixedly connected by bolts 7. Then, the support base 101 at the bottom of the mounting housing 1 is placed on the motor housing. The support base 101 is connected to the motor housing through the mounting hole 102. The connection is fixed, and then the connecting block 404 is connected to the grounding system. When the motor is running, the motor housing may generate static electricity due to friction or electromagnetic induction. Through the contact between the carbon brush body 4 and the motor housing and the grounding system, static electricity and leakage current are discharged, protecting the internal components of the motor, preventing current from accumulating on the motor housing, and extending the service life of the motor. With long-term use, the carbon brush body 4 will wear down and need to be replaced. At this time, simply remove the bolt 7, pull the pull plate 502 outward to drive the clamping rod 501 out of the interior of the second limiting hole 402 and the first limiting hole 301, rotate and open the cover plate 2, slide the carbon brush body 4 downward to disengage the carbon brush body 4 from the clamping plate 3, and then the carbon brush body 4 can be removed and replaced separately. This facilitates quick disassembly and assembly of the carbon brush body 4 without disassembling the housing 1 and the cover plate 2, thus improving the efficiency of disassembly and replacement.
