Description

Technical Field

[0001] The present application relates to the field of car door limiters, and more specifically, to a drainage structure for a car door limiter housing. Background Art

[0002] An automotive door limiter is an important component for connecting the car door and the vehicle body, mainly used to prevent the door from opening excessively and colliding with the vehicle body. The limiter bracket is fastened to the vehicle body by a mounting bolt, and the limit box is fastened to the door by two mounting screws. When the door is opened, the limit box moves along the limit arm. Rainwater easily enters the limit box of the door limiter, and once it enters, it cannot be drained, easily causing corrosion and rust inside the limit box, affecting the service life of the door limiter.

[0003] The patent document with the publication number CN213269388U discloses a car door limiter with a drainage function, including a limit arm and a limit box. A limit block and a limit spring are arranged inside the limit box. The limit box includes a cover plate and a seat plate. Drainage grooves are arranged at both the upper and lower ends of the limit block, and a drainage gap is formed between the drainage grooves and the cover plate and the seat plate. In the above application document, the water inside the limit box is drained through the drainage grooves with an inverted cone structure on the limit block. However, its water blocking ability is limited. When the rain is too heavy, the splashing water droplets easily pass through its gaps and enter the inside of the car door limiter box, resulting in rust. It is not convenient to block water droplets at the gaps of the car door limiter box and not convenient to block most of the water. Summary of the Utility Model

[0022] Embodiment 1

[0023] See Figures 1-4 , this embodiment provides a drainage structure for a car door limiter housing, including a limiter box 1. A limiter main arm 2 is arranged on the inner surface of the limiter box 1. The limiter box 1 and the limiter main arm 2 are components on the car door limiter and are prior art. A water blocking component 3 is arranged between the limiter main arm 2 and the limiter box 1. The water blocking component 3 includes a water blocking frame 301. An opening for accommodating the limiter main arm 2 is arranged on the limiter box 1. The water blocking frame 301 is arranged in the opening. The water blocking frame 301 is fixedly connected to the left side of the limiter box 1. A brush 302 is fixedly connected to the inner surface of the water blocking frame 301. The brush 302 is in contact with the limiter main arm 2. An inner frame 303 is slidably connected to the inner surface of the limiter box 1. A water blocking strip 304 is fixedly connected to the bottom of the inner surface of the inner frame 303. The water blocking strip 304 is arranged at the right side position at the bottom of the inner surface of the inner frame 303. A leakage hole 305 is opened on the left side of the limiter box 1. The inner surface of the leakage hole 305 is inclined. The leakage hole 305 is communicated with the inner surface of the inner frame 303. A limiting component 4 is arranged on the inner surface of the inner frame 303. A guide piece 5 is fixedly connected to the left side of the first limiting seat 401. The material of the guide piece 5 is rubber. The upper part and the bottom of the inner surface of the second limiting seat 402 are provided with inclined surfaces, and the inclined surfaces face the left side.

[0024] When the above-mentioned device is in specific use, the door limiter main arm 2 will move in the limiter box 1 when in use. When it rains, rainwater that hits the outer surface of the limiter box 1 will be blocked by the water retaining frame 301, and water splashing to the opening on the limiter box 1 will be blocked by the brush 302. The rainwater will slide down the hairs on the brush 302, with part of it sliding out to the outer surface of the limiter box 1 and part of it being collected on the inner surface of the limiter box 1. The guide piece 5 on the first limit seat 401 and the inclined surface on the second limit seat 402 can play a further water retaining role. After the rainwater is collected in the limiter box 1, it will be discharged outward from the leakage hole 305 on the limiter box 1, so as to facilitate drainage.

[0025] Example 2

[0026] See also Figures 1-4 On the basis of Example 1, the limiting component 4 includes a first limiting seat 401 and a second limiting seat 402, the first limiting seat 401 and the second limiting seat 402 are in a concave shape, an elastic component 6 is arranged above the first limiting seat 401 and below the second limiting seat 402, the elastic component 6 includes a spring 601, the number of the springs 601 is two, and the two springs 601 are arranged up and down respectively, wherein the spring 601 located at the top is fixedly connected between the first limiting seat 401 and the top of the inner surface of the inner frame 303, and the spring 601 located at the bottom is fixedly connected between the second limiting seat 402 and the bottom of the inner surface of the inner frame 303, and the top of the inner surface of the inner frame 303 is fixedly connected between the second limiting seat 402 and the bottom of the inner surface of the inner frame 303. The top and the bottom are fixedly connected with an insertion rod 602, which is plugged into the first limit seat 401 and the second limit seat 402. There are four insertion rods 602. The first limit seat 401 and the second limit seat 402 are provided with insertion holes for accommodating the insertion rods 602. The limit assembly 4 also includes a limit pad 403. There are two limit pads 403. The two limit pads 403 are respectively fixedly connected to the inner surfaces of the first limit seat 401 and the second limit seat 402. Bolts 7 are threaded through the front and back sides of the limiter box 1. There are four bolts 7, which are symmetrically arranged in pairs on the front and back sides of the limiter box 1. The bolts 7 are threadedly connected to the outer surface of the inner frame 303.

[0027] When the above-mentioned device is in actual use, when the limiter main arm 2 moves in the limiter box 1, the spring 601 will apply elastic force to the first limiter seat 401 and the second limiter seat 402, and at the same time, the insertion rod 602 will slide in the insertion holes on the first limiter seat 401 and the second limiter seat 402, playing a role of limiting and damping. The limit pads 403 on the first limiter seat 401 and the second limiter seat 402 will clamp the limiter main arm 2 to play a role of limiting. When it is necessary to inspect and maintain the parts therein, first loosen the bolts 7 on the limiter box 1, and then pull the inner frame 303 out of the limiter box 1 to facilitate the inspection and maintenance of the limit component 4 and the elastic component 6.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
