[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: As Figures 1-5As shown, this utility model provides a technical solution: a durable and corrosion-resistant drive axle for a new energy harvester, including an axle housing 1, a drive motor 2, a half-shaft 3, and a hub 4. The axle housing 1 includes an upper housing 101 and a lower housing 102. A positioning rod 5 is fixedly installed on the inner side of the upper housing 101, and a positioning sleeve 6 is fixedly installed on the inner side of the lower housing 102. The upper housing 101 and the lower housing 102 are fixedly connected by fixing bolts 7. A sealing gasket 8 is provided between the upper housing 101 and the lower housing 102. An mounting plate 9 is fixedly installed on the side of the lower housing 102. A protective skirt 10 is provided on the side of the mounting plate 9. A protrusion 11 is fixedly installed on the side of the protective skirt 10. A groove 12 is opened on the side of the mounting plate 9. A U-shaped plate 13 is fixedly installed on the side of the mounting plate 9. A limit rod 14 is slidably connected inside the U-shaped plate 13. The protrusion 11... A limiting hole 15 is provided on the side, a limiting plate 16 is fixedly installed on the surface of the limiting rod 14, a tension spring 17 is sleeved on the surface of the limiting rod 14, and a pull plate 18 is fixedly installed on one end of the limiting rod 14. The bridge housing 1 is made of high-strength aluminum alloy, and the outer surface of the bridge housing 1 is coated with a nano-ceramic composite anti-corrosion coating. The positioning rod 5 and the positioning sleeve 6 are slidably connected. The fixing bolt 7 passes through the upper housing 101 and the lower housing 102 and is threadedly connected. The sealing gasket 8 is made of oil-resistant rubber. The protrusion 11 and the groove 12 are slidably connected. The limiting rod 14 and the limiting hole 15 are slidably connected. There are two sets of protective skirts 10, which are located on both sides of the bridge housing 1. One end of the tension spring 17 is fixedly connected to the side of the limiting plate 16, and the other end of the tension spring 17 is fixedly connected to the inner side of the U-shaped plate 13.

[0027] In this embodiment, the bridge housing 1 adopts a split design, consisting of an upper housing 101 and a lower housing 102. The upper housing 101 has a positioning rod 5 inside, and the lower housing 102 has a matching positioning sleeve 6 inside. During assembly, precise alignment is achieved through sliding fit, ensuring stability and sealing when the upper and lower housings 102 are connected. Then, the upper housing 101 and lower housing 102 are fastened together with fixing bolts 7, and an oil-resistant rubber sealing gasket 8 is placed between them. When installing the protective skirt 10, pulling the pull plate 18 causes the limiting rod 14 to slide along the U-shaped plate 13, and the limiting disc 16 compresses the tension spring. Spring 17, aligns the protrusion 11 on the side of the protective skirt 10 with the protrusion 12 of the mounting plate 9 and slides it in. Release the pull plate 18, and the tension spring 17 resets and pushes the limit rod 14 into the limit hole 15 of the protrusion 11 to fix the protective skirt 10. The two sets of protective skirts 10 protect the two sides of the bridge shell 1 respectively, which can effectively block the direct impact of field gravel and soil on the bridge shell 1 and reduce the wear on the surface of the bridge shell 1. The high-strength aluminum alloy bridge shell 1, combined with the nano-ceramic composite anti-corrosion coating on the outer surface, improves the overall corrosion resistance and strength.

[0028] Example 2: Figures 1-5As shown, an oil filling groove 19 is provided on the surface of the upper housing 101, an opening and closing plate 20 is slidably connected inside the upper housing 101, a connecting plate 21 is fixedly connected to the side of the opening and closing plate 20, a tension spring 22 is fixedly connected to the inside of the upper housing 101, sliding blocks 23 are fixedly connected to both sides of the opening and closing plate 20, a sliding groove 24 is provided on the inside of the upper housing 101, a toggle block 25 is fixedly installed on the surface of the opening and closing plate 20, one end of the tension spring 22 is fixedly connected to the side of the connecting plate 21, there are two sets of tension springs 22, and the sliding blocks 23 are slidably connected to the sliding groove 24.

[0029] In this embodiment, when oil injection is required, the toggle block 25 is moved to drive the opening and closing plate 20 to move, the sliding block 23 slides along the slide groove 24, the connecting plate 21 stretches the tension spring 22, so that the opening and closing plate 20 opens the oil injection groove 19. After oil injection is completed, the toggle block 25 is released, and the two sets of tension springs 22 pull the connecting plate 21 at the same time, driving the opening and closing plate 20 to reset and close the oil injection groove 19, so as to prevent impurities from entering the bridge housing 1 through the oil injection groove 19. The cooperation between the sliding block 23 and the slide groove 24 ensures that the opening and closing plate 20 moves smoothly. The entire oil injection operation does not require tools and is convenient and efficient.

[0030] The working principle of this embodiment is as follows: The bridge housing 1 adopts a split structure design, consisting of an upper housing 101 and a lower housing 102. During installation, the positioning rod 5 on the inner side of the upper housing 101 is aligned with the positioning sleeve 6 on the inner side of the lower housing 102 and slid in to make the upper housing 101 and the lower housing 102 precisely connected. An oil-resistant rubber sealing gasket 8 is placed between the two. Then, the fixing bolt 7 is used to pass through the upper housing 101 and the lower housing 102 and tightened to complete the assembly of the bridge housing 1. When installing the protective skirt 10 on both sides of the bridge housing 1, the protrusion 11 on the protective skirt 10 is aligned with the groove 12 on the mounting plate 9 and slid in along the direction of the groove 12. When the protrusion 11 is fully inserted into the groove 12, the pull plate 18 on the limiting rod 14 is pulled to compress the tension spring 17 and adjust the position of the limiting rod 14 so that it is inserted into the limiting hole 15 on the protrusion 11 to complete the fixing of the protective skirt 10. The tension spring 17 provides the restoring force and can automatically engage the limit rod 14 and the limit hole 15 after the pull plate 18 is released, ensuring that the protective skirt 10 is firmly installed. When lubricating oil needs to be added, the toggle block 25 is manually moved to drive the opening and closing plate 20 to move. The sliding blocks 23 on both sides of the opening and closing plate 20 slide along the slide groove 24, so that the opening and closing plate 20 opens the oil injection groove 19. At this time, lubricating oil can be injected into the bridge housing 1 through the oil injection groove 19. After releasing the toggle block 25, the tension spring 22 drives the opening and closing plate 20 to automatically reset through the connecting plate 21, closing the oil injection groove 19 to prevent lubricating oil leakage and external impurities from entering. During the operation of the equipment, the nano-ceramic composite anti-corrosion coating on the surface of the bridge housing 1 effectively resists the corrosion of the field's humid and acidic / alkaline environment, extending its service life. The protective skirt 10 is located on both sides of the bridge housing 1, blocking gravel, soil and other impurities from directly impacting the bridge housing 1 during operation, reducing the risk of wear on the bridge housing 1, and facilitating disassembly, cleaning or replacement.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
