[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides an embodiment of an easy-to-maintain car door handle, comprising a car door 1 made of high-strength metal material with a certain thickness to ensure the overall structural stability; a fixing component 2 made of corrosion-resistant plastic material installed on the front side of the car door 1 for securely connecting the handrail assembly 3 and the car door 1; a handrail assembly 3 with multiple practical functions installed on the front side of the fixing component 2; the handrail assembly 3 includes a handle body 301 made of engineering plastic with a smooth surface and a certain degree of flexibility; and a non-slip texture 3 made of rubber material is fixedly connected to the bottom of the handle body 301. 07. The anti-slip texture 307 is designed in accordance with the ergonomic palm print pattern, which can effectively increase the friction between the hand and the handle and prevent slippage when gripping. At the four corners of the bottom of the handle body 301, there are fixed positioning posts 302 made of stainless steel with a polished surface. These positioning posts 302 are used to precisely mate with the positioning holes 204 on the fixing component 2 to achieve quick positioning and installation. A baffle 303 made of lightweight aluminum alloy with a smooth surface and a certain strength is slidably connected to the inner wall of the handle body 301. A lever made of a highly elastic metal sheet is fixedly connected to the right side of the baffle 303. The paddle 304 has beveled edges and corners to effectively prevent hand scratches during operation. A spring 305 is fixedly connected to the right side of the paddle 304, and a stainless steel fixing post 306 with rust-proof surface treatment is fixedly connected to the other side of the spring 305. The outer wall of the fixing post 306 is slidably connected to the inside of the handle body 301, and springs 305 are fixedly connected to both ends of the fixing post 306. Similarly, the outer wall of the springs 305 is slidably connected to the inside of the handle body 301, serving as a buffer and reset function. The fixing component 2 includes components made of high-strength plastic. The mounting base 201 is made of a robust and resilient material. The inner wall of the mounting base 201 is threaded with screws 202 made of high-strength metal and galvanized to prevent rust. The mounting base 201 is designed with a fixing groove 203 to accommodate the positioning post 302, and the bottom of the fixing groove 203 is provided with positioning holes 204 that are compatible with the positioning post 302. The handle body 301 is designed with chamfered edges and corners to effectively prevent injury to the human body during collisions. The handle body 301 is hollow inside, which reduces the overall weight and manufacturing cost.

[0021] Reference Figure 3The mounting base 201 is made of high-strength and tough engineering plastic material. The inner walls of the four corners of the mounting base 201 are threaded to the outer walls of screws 202 made of high-strength metal material to extend service life. This threaded connection method is not only stable to install, but also facilitates subsequent disassembly and maintenance. The fixing groove 203 for accommodating the positioning post 302 for precise positioning is located in the center of the mounting base 201. Its position design is reasonable and can ensure the balance and stability of the handrail assembly 3 during installation. The positioning hole 204 for cooperating with the positioning post 302 to achieve a fixing function is opened at the bottom of the mounting base 201. The size of the positioning hole 204 is adapted to the positioning post 302, which can effectively prevent the handrail assembly 3 from shaking or shifting after installation.

[0022] Working Principle: When installing this car door handle, the operator first applies an inward squeezing force to the paddle 304, made of a high-elasticity metal sheet and with chamfered edges and corners to prevent hand scratches, which is installed inside the hollow handle body 301. Under this squeezing force, the paddle 304 overcomes the elastic resistance of the spring 305, made of high-strength steel spring 305, which connects the paddle 304 to the fixing post 306 at both ends. This causes the two side baffles 303, made of lightweight aluminum alloy with a smooth surface and a certain strength, to retract inward along the inner wall of the handle body 301. At this time, the baffles 303 compress the spring 305, causing it to undergo elastic deformation and accumulate elastic potential energy. Then, the positioning posts 302, made of stainless steel with a polished surface and precise dimensions, at the four corners of the bottom of the handle body 301, are aligned with the positioning holes at the bottom of the mounting base 201, which are made of corrosion-resistant plastic and are compatible with the dimensions of the positioning posts 302. 204. After the positioning pin 302 is accurately inserted into the positioning hole 204, the operator releases the pressure on the lever 304. At this time, the spring 305 releases the elastic potential energy it had previously stored because it is no longer compressed by external force. Under the action of the elastic restoring force of the spring 305, the two side baffles 303 extend outwards towards the handle body 301 until the baffles 303 completely overlap with the pre-designed slots inside the mounting base 201 for fixing with the baffles 303. Through the interlocking action of the baffles 303 and the slots, the handle body 301 is securely installed on the mounting base 201, thereby achieving the modular installation effect between the various components of the car door handle. When the car door handle needs to be disassembled, replaced, or maintained in the future, the operator squeezes the lever 304 again to make the baffles 303 retract and disengage from the slots, and the handle body 301 can be easily removed. The whole process is simple to operate and greatly improves the maintainability of the car door handle.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
