If it is not cleaned in time, the rear axle of the electric tricycle may be corroded or even damaged, posing certain safety hazards. Utility Model Content
[0004] In order to solve the problems existing in the prior art, the utility model provides an anti-corrosion electric vehicle rear axle, which drives the skateboard to rotate and contact the surface of the shell through a fixed plate, thereby cleaning the water stains and dirt on the surface of the shell and preventing the shell from corrosion.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-corrosion electric vehicle rear axle, comprising a rear axle body, a motor, a differential and a housing, the motor being mounted on the surface of the differential, both ends of the differential being rotatably connected with half-shafts, one end of the housing being fixedly connected to the surface of the differential, and the housing being movably sleeved on the surface of the half-shafts, both ends of the differential being fixedly connected with annular plates, the surface of the annular plates being provided with annular grooves, the interior of the annular grooves being slidably connected with sliders, the end of the slider away from the annular grooves being fixedly connected with a fixing plate, the end of the half-shaft away from the differential being fixedly connected with the fixing plate, the surface of the fixing plate being provided with a card slot, the lower end of the fixing plate being fixedly connected with a scraper, the surface of the housing being fixedly connected with an arc-shaped convex strip, one end of the fixing plate being provided with a fixing hole, the interior of the fixing hole being fixedly connected with a cylinder, and one end of the cylinder being fixedly connected with a card block.
[0006] Furthermore, one end of the clamping block is a curved surface.
[0007] Furthermore, the scraper is an elastic scraper.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] 1. The fixed plate drives the sliding plate to rotate and contact the surface of the shell, so as to clean the water stains and dirt on the surface of the shell to prevent the shell from being corroded. Through the setting of the arc-shaped convex strips, when the scraper contacts the surface of the arc-shaped convex strips, the scraper will be deformed when it contacts it due to the arc-shaped setting of the surface of the arc-shaped convex strips. After moving away from the arc-shaped convex strips, the scraper can shake off the water stains and dirt on its surface through its own rebound, which is convenient for use.
[0010] 2. Start the cylinder to drive the block to move toward the fixed disk. When the block enters the slot on the surface of the fixed disk, the fixed disk rotates so that the inner wall of the slot contacts the block, driving the cylinder to rotate. The cylinder drives the fixed plate to rotate, and the fixed plate drives the slider to slide inside the annular groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example
[0016] See attached Figure 1-2As shown, an anti-corrosion electric vehicle rear axle comprises a rear axle body 1, a motor, a differential and a housing, the motor is mounted on the surface of the differential, both ends of the differential are rotatably connected with half shafts, one end of the housing is fixedly connected to the surface of the differential, and the housing is movably sleeved on the surface of the half shaft, both ends of the differential are fixedly connected with annular plates 2, the surface of the annular plate 2 is provided with an annular groove, a slider 3 is slidably connected inside the annular groove, one end of the slider 3 away from the annular groove is fixedly connected with a fixing plate 4, one end of the half shaft away from the differential is fixedly connected with a fixing plate 6, a clamping groove 7 is provided on the surface of the fixing plate 6, a scraper 5 is fixedly connected to the lower end of the fixing plate 4, an arc-shaped convex strip 10 is fixedly connected to the surface of the housing, a fixing hole is provided at one end of the fixing plate 4, a cylinder 8 is fixedly connected inside the fixing hole, and a clamping block 9 is fixedly connected to one end of the cylinder 8.
[0017] One end of the clamping block 9 is a curved surface.
[0018] The scraper 5 is an elastic scraper 5 .
[0019] Working principle: the rear axle body 1 is a common three-wheeled vehicle rear axle on the market. The working principle will not be repeated here. The electric motor provides power input to the differential, so that the differential drives the two half-axles to rotate, and the half-axles drive the fixed plate 6 to rotate. When it is necessary to clean the water stains and dirt on the surface of the shell, the cylinder 8 can be started to drive the block 9 to move toward the fixed plate 6. When the block 9 enters the groove 7 on the surface of the fixed plate 6, the inner wall of the groove 7 contacts the block 9 due to the rotation of the fixed plate 6, which drives the cylinder 8 to rotate, and the cylinder 8 drives the fixed plate 4 to rotate, and the fixed plate 4 drives the slider 3 in the annular groove. The internal sliding drives the sliding plate to rotate and contact the surface of the shell through the fixed plate 4, so as to clean the water stains and dirt on the surface of the shell to prevent the shell from being corroded. Through the setting of the arc convex strip 10, when the scraper 5 contacts the surface of the arc convex strip 10, the arc-shaped surface of the arc convex strip 10 will cause the scraper 5 to deform when contacting it. After moving away from the arc convex strip 10, the scraper 5 can shake off the water stains and dirt on its surface through its own rebound, which is convenient for use. When cleaning is not needed, the cylinder 8 can be started to drive the block 9 to disengage from the inside of the slot 7, thereby reducing the wear of the scraper 5 on the shell surface.
