Description

Technical Field

[0001] This application relates to the field of door limiters, and more particularly, to a door limiter that can reduce vibration and noise. Background Art

[0002] The function of a door opening limiter is to limit the degree to which the door can be opened. On the one hand, it can limit the maximum opening of the door to prevent the door from opening too wide. On the other hand, it can keep the door open when needed. For example, when the car is parked on a slope or there is a general wind, the door will not close automatically. A common door opening limiter is a separate belt-type limiter, and some limiters are integrated with the door hinge. Usually, it has a limiting function when the door is fully open and half open.

[0003] The patent document with the publication number CN217269506U discloses a door limiter that can reduce vibration and noise, which relates to the technical field of door limiters. To solve the problem that the support for the main arm of the existing ordinary door limiter is not stable enough, resulting in excessive friction and noise when the door limiter is used. Inside the limiter box, a first sliding disk and a second sliding disk are respectively installed, and both the first sliding disk and the second sliding disk are slidably connected to the limiter box. A first bracket is installed below the first sliding disk, and the first bracket and the first sliding disk are fixedly connected by fastening screws. A second bracket is installed below the second sliding disk, and the second bracket and the second sliding disk are fixedly connected by fastening screws. A first fixed pressing wheel is installed below the first bracket, and the first fixed pressing wheel and the first bracket are rotationally connected by a coupling. A second fixed pressing wheel is installed below the second bracket, and the second fixed pressing wheel and the second bracket are rotationally connected by a coupling. In the above application document, pressure is applied for support through the second spring and the third spring, so that the main arm of the limiter slides more smoothly, and thus the main arm of the limiter will not be overly rubbed when sliding, reducing the noise during friction. However, the pressing head used to limit the main arm of the limiter will slide in the limiter box as the main arm of the limiter is pulled, thus generating noise, and it is not convenient to reduce the noise by setting a sound-absorbing structure in the limiter box.

Detailed implementation manners

[0020] In order to enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0021] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the accompanying drawings and combine with the embodiments to detail this application.

[0022] Embodiment 1

[0023] See Figures 1-4, this embodiment provides a door limiter that can reduce vibration and noise, including a housing 1. An inner surface of the housing 1 is provided with a main limiter arm 2. The housing 1 is provided with an opening for accommodating the main limiter arm 2, and a sponge layer that fits with the main limiter arm 2 is arranged in the opening for sound absorption. Above the main limiter arm 2, a first limiting component 3 is provided. The first limiting component 3 includes a first limiting seat 301. The shape of the first limiting seat 301 is L-shaped. A first spring 302 is elastically connected between the first limiting seat 301 and the top of the inner surface of the housing 1. The top of the inner surface of the housing 1 is fixedly connected with a first limiting strip 303. The first limiting strip 303 is inserted above the first limiting seat 301. A first sponge sleeve 304 is slidably connected to an outer surface of the first limiting strip 303. The first sponge sleeve 304 is fixedly connected above the first limiting seat 301. Below the first limiting component 3, a second limiting component 4 is provided. The second limiting component 4 includes a second limiting seat 401. The shape of the second limiting seat 401 is L-shaped. A second spring 402 is elastically connected between the second limiting seat 401 and the bottom of the inner surface of the housing 1. The bottom of the inner surface of the housing 1 is fixedly connected with a second limiting strip 403. The second limiting strip 403 is inserted below the second limiting seat 401. A second sponge sleeve 404 is slidably connected to an outer surface of the second limiting strip 403. The second sponge sleeve 404 is fixedly connected below the second limiting seat 401. The first limiting component 3 further includes a first pressing wheel 305. The first pressing wheel 305 is rotatably connected to an inner surface of the first limiting seat 301. An inner surface of the sound insulation board 6 is fixedly connected to the inner surface of the housing 1. A convex structure is arranged on the inner surface of the sound insulation board 6 and fits with the first limiting seat 301 and the second limiting seat 401.

[0024] When the above device is specifically used, the main limiter arm 2 moves in the housing 1 to limit the door. When the main limiter arm 2 moves, the first spring 302 and the second spring 402 will respectively apply elastic forces to the first limiting seat 301 and the second limiting seat 401, so that the first pressing wheel 305 and the second pressing wheel 405 clamp the main limiter arm 2 to limit the main limiter arm 2. When the first limiting seat 301 and the second limiting seat 401 move under the action of the first spring 302 and the second spring 402, they will slide on the first limiting strip 303 and the second limiting strip 403. At this time, the first sponge sleeve 304 and the second sponge sleeve 404 will also slide on the first limiting strip 303 and the second limiting strip 403. The first sponge sleeve 304 and the second sponge sleeve 404 will absorb the friction sound transmitted from the gap to reduce noise. At the same time, when the housing 1 shakes, the sound insulation board 6 in the housing 1 will absorb noise to achieve the effect of noise reduction.

[0025] Embodiment 2

[0026] See Figures 1-4, on the basis of Embodiment 1, the second limiting component 4 further includes a second pressing wheel 405. The second pressing wheel 405 is rotatably connected to the inner surface of the second limiting seat 401. An oil injection component 5 is arranged on the front surfaces of the first pressing wheel 305 and the second pressing wheel 405. The oil injection component 5 includes a guiding groove 501. The guiding groove 501 is formed above the second limiting seat 401. An oil injection port 502 is fixedly connected to the front surface of the housing 1. The number of the oil injection ports 502 is two. The two oil injection ports 502 are respectively adapted to the first pressing wheel 305 and the second pressing wheel 405. A channel is arranged on the first limiting seat 301 for communicating with the upper oil injection port 502. The lower oil injection port 502 is communicated with the second limiting seat 401 through the guiding groove 501. Holes for communicating with the oil injection port 502 are arranged on the housing 1 and the sound insulation board 6.

[0027] When the above device is in specific use, when the main arm 2 of the limiter moves, the first pressing wheel 305 and the second pressing wheel 405 will roll to reduce the noise generated by friction. When it is necessary to lubricate the first pressing wheel 305 and the second pressing wheel 405, lubricating oil is injected through the oil injection port 502. After the lubricating oil is injected into the upper oil injection port 502, the lubricating oil will be conveyed to the position of the first pressing wheel 305 through the channel in the first limiting seat 301. After the lubricating oil is injected into the lower oil injection port 502, the lubricating oil will flow to the position of the second pressing wheel 405 through the guiding groove 501 above the second limiting seat 401, so that it can rotate smoothly, thereby reducing the noise generated by rotation.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
