Detailed Embodiment

[0023] The following further elaborates on this application in conjunction with the attached Figures 1-4 drawings for a more detailed description.

[0024] The embodiment of this application discloses a waterproof mechanism for an electric sanitation vehicle motor. Referring to Figures 1-4 , a waterproof mechanism for an electric sanitation vehicle motor includes a base 1 and a protective housing 2 arranged above the base 1. The outer wall of the base 1 is installed with a motor 3, and the end of the output shaft of the motor 3 penetrates and extends below the base 1. A partition ring 4 is fixedly connected to the outer wall of the top of the base 1, and the outer wall of the partition ring 4 is in contact with the inner wall of the protective housing 2. A tight groove 5 is opened on the outer wall of the partition ring 4, and a hollow rubber ring 6 is bonded to the inner wall of the protective housing 2. The hollow rubber ring 6 is squeezed and clamped into the inner wall of the tight groove 5, and the outer wall of the hollow rubber ring 6 is in close contact with the inner wall of the tight groove 5. The inner diameter of the tight groove 5 is smaller than the outer diameter of the hollow rubber ring 6. A fixing mechanism for facilitating the disassembly and assembly of the protective housing 2 is installed on the outer wall of the top of the base 1.

[0025] The fixing mechanism includes two fixing plates 7 symmetrically and fixedly connected to the outer wall of the top of the base 1. A fixing frame 9 is fixedly connected to the outer wall of the fixing plate 7. Two fixing rods 10 are fixedly connected to the outer wall of the fixing frame 9 facing the fixing plate 7. A movable plate 12 is slidably connected to the outer walls of the two fixing rods 10. A clamping block 13 is fixedly connected to the outer wall of the movable plate 12 facing the fixing plate 7.

[0026] The fixing mechanism further includes two clamping grooves 8 symmetrically formed in the outer wall of the protective housing 2. The two clamping grooves 8 correspond to the two clamping blocks 13. One end of the clamping block 13 away from the movable plate 12 penetrates through the fixing plate 7 and is clamped with the clamping groove 8. A first spring 11 is installed on the outer wall of the fixing rod 10. The first spring 11 is located between the movable plate 12 and the fixing frame 9.

[0027] Two middle outer walls of the sides of the two movable plates 12 away from the fixing plate 7 are fixedly connected with a pull rod member 14. One end of the pull rod member 14 away from the movable plate 12 penetrates through the fixing frame 9.

[0028] A plurality of positioning columns 15 are fixedly connected to the outer wall of the top of the base 1. A plurality of positioning blocks 16 are fixedly connected to the outer wall of the motor 3. The positioning blocks 16 are inserted into the outer walls of the positioning columns 15.

[0029] A plurality of telescopic rods 17 are fixedly connected to the outer wall of the bottom of the protective housing 2. The bottom ends of the plurality of telescopic rods 17 are fixedly connected with a pressing ring 18. The pressing ring 18 is attached to the outer wall of the top of the motor 3. Second springs 19 are installed on the outer walls of the plurality of telescopic rods 17.

[0030] A fixed bottom ring 20 is fixedly connected to the outer wall of the bottom of the base 1. Through a plurality of mounting holes preset on the outer wall of the fixed bottom ring 20, the motor 3 and its external waterproof mechanism can be integrally installed at a suitable position on the electric sanitation vehicle by using fastening screws.

[0031] The implementation principle of a waterproof mechanism for an electric motor of an electric sanitation vehicle in an embodiment of the present application is as follows: During use, the motor 3 is installed on the top of the base 1, aligning multiple positioning blocks 16 on the outer wall of the base 1 with multiple positioning posts 15 on the top of the base 1, and inserting the positioning blocks 16 on the outer wall of the positioning posts 15, thereby positioning the motor 3. At this time, the output end of the motor 3 penetrates the middle outer wall of the base 1, and then the protective housing 2 is spliced above the base 1, with the edge of the protective housing 2 located between the fixing plate 7 and the partition ring 4. Since the inner diameter of the protective housing 2 is adapted to the outer diameter of the partition ring 4, when the protective housing 2 is inserted into the base 1, the inner wall of the protective housing 2 will be in contact with the outer wall of the partition ring 4. At the same time, the hollow rubber ring 6 on the outer wall of the protective housing 2 will be squeezed and clamped into the tight groove 5. Since the inner diameter of the tight groove 5 is smaller than the outer diameter of the hollow rubber ring 6, and the hollow rubber ring 6 has a certain flexibility and elasticity, when the hollow rubber ring 6 is squeezed and clamped into the tight groove 5, the elastic force on the surface of the hollow rubber ring 6 makes its outer wall closely fit with the inner wall of the tight groove 5, forming a good soft seal, thus sealing the gap between the protective housing 2 and the base 1, making the inside of the protective housing 2 have good tightness and preventing rainwater from entering the protective housing 2 and corroding the motor 3;

[0032] When the protective housing 2 and the base 1 are spliced, the fixing mechanism will be automatically triggered. When the bottom outer wall of the protective housing 2 moves towards the base 1, it will surely contact the upward slopes at the ends of the two clamping blocks 13. Through the slopes at the ends of the clamping blocks 13, the protective housing 2 can easily squeeze the clamping blocks 13 outwards. The clamping blocks 13 will drive the movable plate 12 to slide outwards on the outer wall of the fixed rod 10, and the movable plate 12 will squeeze the first spring 11. The first spring 11 deforms to generate elastic force. When the bottom of the protective housing 2 contacts the top of the base 1, the two card slots 8 on the outer wall of the protective housing 2 correspond to the clamping blocks 13. At this time, the outer wall of the protective housing 2 no longer squeezes the clamping blocks 13, and the movable plate 12 will be driven by the elastic force of the first spring 11 to reset the clamping blocks 13. When the clamping blocks 13 are reset, they will be clamped with the card slots 8. At this time, the protective housing 2 cannot be pulled upwards and is thus fixed;

[0033] When it is necessary to release the fixation, pull the pull rod member 14 outwards. The pull rod member 14 drives the movable plate 12 to slide outwards on the outer wall of the fixed rod 10. The movable plate 12 drives the clamping blocks 13 to disengage from the card slots 8, and the protective housing 2 can be pulled upwards, thus releasing the locking of the protective housing 2.

[0034] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected.
