Description

Technical Field

[0001] This utility model relates to the field of automotive damper technology, and in particular to a limiting structure for preventing automotive dampers from derailing. Background Technology

[0002] In automotive air conditioning systems, the air dampers play a crucial role in regulating ventilation volume and airflow direction, directly affecting the temperature control and air quality inside the vehicle. However, existing automotive air dampers have some serious problems in actual use. Because vehicles experience various complex road conditions during driving, generating frequent vibrations and bumps, the air dampers are prone to derailment. Once derailed, the damper cannot move normally along its intended path, causing the airflow regulation function of the ventilation duct to fail. For example, the damper may deviate from its original position, causing partial blockage of the ventilation duct or preventing it from fully opening, resulting in insufficient or excessive airflow in certain areas of the vehicle, affecting passenger comfort.

[0003] Moreover, the existing damper limiting structure is not perfect. It does not limit the rotation range of the car damper, and under long-term use and frequent vibration, it is prone to loosening or damage, and cannot continuously and stably limit the damper, which further increases the risk of damper derailment. Utility Model Content

[0004] The purpose of this utility model is to provide a limiting structure for preventing the car damper from derailing. The first stop bar, the first limiting part, and the second limiting part cooperate to prevent the car damper from falling off the movement track, deviating from the track, and causing the product's airflow to fail.

[0005] To achieve the above objectives, this utility model provides a limiting structure for preventing derailment of an automotive damper, including an automotive damper, a housing, and a limiting component. The mounting shaft of the automotive damper is hinged to the upper part of the ventilation channel of the housing. The automotive damper is connected to a sealing sleeve. A first stop bar is provided at the top of the ventilation channel behind the sealing sleeve. The ventilation channel is symmetrically provided with a first limiting part and a second limiting part of the limiting component below the mounting shaft. The first limiting part and the second limiting part have the same structure. The upper part of the first limiting part has an arc-shaped structure that matches the curvature of the mounting shaft, and the lower part of the first limiting part is connected to the side wall of the ventilation channel.

[0006] Preferably, the sealing sleeve includes a sealing block and a sealing ring. The sealing block has sealing rings symmetrically arranged at both ends, and a sealing ring is connected to the bottom of the sealing ring. The sealing ring is connected to the car's air damper.

[0007] Preferably, the sealing ring is matched with the shape of the car damper, and the upper diameter of the sealing ring is larger than the lower diameter of the sealing ring.

[0008] Preferably, the mounting shaft of the automotive damper is provided with symmetrical positioning grooves, and the width of the positioning grooves matches that of the sealing ring.

[0009] Preferably, the ventilation channel is shaped to match the sealing ring, the lower part of the first limiting part is connected to the upper sidewall of the ventilation channel, and the distance between the lower parts of the first limiting part and the lower parts of the second limiting part is the same as the width of the lower part of the ventilation channel.

[0010] Preferably, the length of the first stop bar is greater than the length of the sealing block.

[0011] Preferably, the distance between the top ends of the first limiting part and the second limiting part is less than the length of the upper part of the car damper.

[0012] Therefore, the present invention adopts a limiting structure for preventing derailment of a car air damper with the above-mentioned structure. The sealing ring matches the shape of the car air damper so that it can fit tightly against the car air damper and provide a sealing effect. The first stop bar, the first limiting part, and the second limiting part cooperate to restrict the movement of the car air damper and ensure the stable movement of the car air damper in the ventilation channel in all directions.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The features mentioned above or in the specific examples mentioned in this invention can be combined arbitrarily, and these specific embodiments are only used to illustrate this invention and are not intended to limit the scope of this invention.

[0021] Example

[0022] like Figures 1-2 As shown, this utility model provides a limiting structure for preventing derailment of an automotive damper, including an automotive damper 1, a housing 2, and a limiting assembly. The mounting shaft 3 of the automotive damper 1 is hinged to the upper part of the ventilation channel 4 of the housing 2. The automotive damper 1 is connected to a sealing sleeve 5. A first stop bar 6 is provided at the top of the ventilation channel 4 behind the sealing sleeve 5. A first limiting part 7 and a second limiting part 8 of the limiting assembly are symmetrically provided below the mounting shaft 3 in the ventilation channel 4. The first limiting part 7 and the second limiting part 8 have identical structures. The upper part of the first limiting part 7 has an arc-shaped structure matching the curvature of the mounting shaft 3, and the lower part of the first limiting part 7 is connected to the side wall of the ventilation channel 4.

[0023] The car damper 1 is connected to the housing 2 and moves relative to the housing 2. A limiting component restricts the movement trajectory of the car damper 1 within the ventilation channel 4 of the housing 2, preventing the car damper 1 from deviating from its trajectory during movement and thus preventing loss of airflow regulation. When the car damper 1 rotates, the mounting shaft 3 rotates along the mounting hole in the ventilation channel 4, and the rotation of the car damper 1 causes the connected sealing sleeve 5 to move together. The first limiting part 7, the second limiting part 8, and the first stop bar 6 limit the movement trajectory of the car damper 1 by contacting its upper part and top.

[0024] like Figure 3 As shown, the sealing sleeve 5 includes a sealing block 51 and a sealing ring 52. The sealing block 51 has sealing rings 52 symmetrically arranged at both ends. A sealing ring 53 is connected to the bottom of the sealing ring 52, and the sealing ring 53 is connected to the car damper 1. During the movement of the car damper 1, the sealing sleeve 5 contacts the side wall of the ventilation channel 4, achieving the sealing effect of the car damper 1, and at the same time, limiting the movement trajectory of the car damper 1 within the ventilation channel 4.

[0025] The sealing ring 53 is shaped to match the car damper 1, and the upper diameter of the sealing ring 53 is larger than the lower diameter of the sealing ring 53. The shape of the sealing ring 53 ensures the sealing effect of the sealing ring 53 on the car damper 1.

[0026] like Figure 4 As shown, the mounting shaft 3 of the car damper 1 is symmetrically provided with positioning grooves 9, the positioning grooves 9 and the sealing ring 52 are matched in width, and the positioning grooves 9 and the sealing ring 52 are connected.

[0027] The ventilation channel 4 matches the shape of the sealing ring 53. The lower part of the first limiting part 7 is connected to the upper side wall of the ventilation channel 4. The distance between the lower part of the first limiting part 7 and the lower part of the second limiting part 8 is the same as the width of the lower part of the ventilation channel 4.

[0028] When the car damper 1 moves, the upper part of the first limiting part 7 and the upper part of the second limiting part 8 prevent the car damper 1 from continuing to move outward.

[0029] The length of the first stop bar 6 is greater than the length of the sealing block 51. The first stop bar 6 prevents the entire car damper 1 from continuing to rotate backward by contacting the top of the car damper 1 and the sealing block 51.

[0030] The distance between the top ends of the first limiting part 7 and the second limiting part 8 is less than the length of the upper part of the car damper 1, so that the car damper 1 as a whole can be prevented from continuing to rotate forward by contacting the upper part of the car damper 1.

[0031] Therefore, this utility model adopts a limiting structure for preventing the car air damper from derailing, with the first stop bar, the first limiting part and the second limiting part cooperating to prevent the car air damper from derailing from the movement track and causing the product's airflow to fail.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
