[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 The noise-reducing and wear-resistant exterior door handle includes a door body 1, a fixed base body 2 fixedly connected to the front surface of the door body 1, a fingerprint sensor 3 on the front surface of the fixed base body 2, a handle body 4 rotatably connected to the front surface of the door body 1, a first handle protective shell 5 and a second handle protective shell 6 respectively fitted onto the upper and lower surfaces of the handle body 4, a first insertion groove 7 opened on the lower front surface of the first handle protective shell 5, an insertion block 8 matching the first insertion groove 7 on the upper front surface of the second handle protective shell 6, an insertion block 8 at the upper end of the insertion block 8 with a first inclined surface 9 that slopes downward and upward, a first locking device on the rear surface of the insertion block 8, and a second locking device between the rear of the first handle protective shell 5 and the rear of the second handle protective shell 6.

[0021] The first mounting device includes two mounting slots 10, both of which are located inside the first handle protective shell 5. Each of the two mounting slots 10 has a movable block 11 inside, and each of the two movable blocks 11 has mounting ears 12 on its upper and lower sides. Each of the mounting ears 12 has a sliding rod 13 slidably connected inside. The sliding rod 13 is used to move the movable block 11 along the sliding rod 13, making the movement of the movable block 11 more stable. Multiple sliding rods 13 are fixedly connected to the inner walls of the front and rear sides of the mounting groove 10. Each sliding rod 13 is fitted with a spring 14. One end of each spring 14 is fixedly connected to the inner rear wall of the mounting groove 10, and the other end of each spring 14 is fixedly connected to the rear surface of the mounting ear 12. Each of the two moving blocks 11 has two first locking blocks 15 on its front surface. Each of the two first locking blocks 15 has a second inclined surface 16 that slopes upward from back to front. The rear surface of the insertion block 8 has a first locking groove 17 that corresponds to each of the first locking blocks 15. The first locking blocks 15 match the first locking grooves 17. The inner front wall of the first insertion groove 7 has two first operating holes 18 that correspond to each of the moving blocks 11. The inner rear wall of the first insertion groove 7 has two second operating holes 19 that correspond to each of the moving blocks 11. The surface of the insertion block 8 has two third operating holes 20 that correspond to each of the moving blocks 11. The vertical length of the third operating hole 20 is greater than the vertical length of the first locking block 15. This arrangement facilitates the first locking groove 17 to disengage from the first locking block 15.

[0022] Both first operating holes 18 have concealed grooves 21 at their upper ends, and rubber plugs 22 are fitted into the inner walls of the concealed grooves 21. The rubber plugs 22 serve a protective function to prevent dust and foreign objects from entering the first operating holes 18.

[0023] The second locking device includes a second insertion groove 23 and two elastic fixing blocks 24. The second insertion groove 23 is opened on the lower rear surface of the first handle protective shell 5, and the two elastic fixing blocks 24 are set on the upper rear surface of the second handle protective shell 6. Two second locking slots 25 are opened on the front and rear inner walls of the second insertion groove 23. Two second locking blocks 26 are provided on the opposite side of the two elastic fixing blocks 24. The multiple second locking blocks 26 correspond one-to-one with the multiple second locking slots 25 and are locked together.

[0024] An elastic pad 27 is provided between the first handle protective shell 5 and the second handle protective shell 6. The elasticity of the elastic pad 27 makes the first handle protective shell 5 and the second handle protective shell 6 more tightly connected.

[0025] The front and rear surfaces of the first handle protective shell 5 are provided with multiple anti-slip and wear-resistant particles 28. These particles 28 serve to prevent slippage and wear, thus avoiding damage to the first handle protective shell 5 and providing an anti-slip function.

[0026] Working principle: When installing the first handle protective shell 5 and the second handle protective shell 6, the insert block 8 is inserted into the first insert groove 7 through the first locking device. The first inclined surface 9 pushes the second inclined surface 16, causing the first locking block 15 to move backward, which in turn causes the moving block 11 to move backward and compress the spring 14. The insert block 8 moves upward, causing the first locking block 15 to slide into the first locking groove 17 and engage with it. At the same time, through the second locking device, the elastic fixing block 24 is inserted into the second insert groove 23. The elastic action of the elastic fixing block 24 causes the second locking block 26 to engage with the second locking groove 25. When disassembling the first handle protective shell 5 and the second handle protective shell 6, first remove the rubber plug 22, and then use a rod-like tool or roller-like tool to insert into the first operating hole 18, the third operating hole 20 and the second operating hole 19. Push the moving block 11 with the rod-like tool to move the moving block 11 backward until the first locking block 15 disengages from the first locking groove 17. Then pull the second handle protective shell 6 to disengage the inserting block 8 from the first inserting groove 7. At the same time, disengage the second locking block 26 from the second locking groove 25, and then disengage the elastic fixing block 24 from the second inserting groove 23. Finally, remove the second handle protective shell 6.

[0027] In summary, the first handle protective shell 5 and the second handle protective shell 6 of this car door exterior handle can be completely separated, making it convenient to clean the inner walls of the first handle protective shell 5 and the second handle protective shell 6; no components of this car door exterior handle are exposed to the outside, and the first handle protective shell 5 and the second handle protective shell 6 can only be separated by using a stick-like tool to push the moving block 11, which reduces the likelihood of misoperation.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
