Description

Technical Field

[0001] This utility model relates to the field of automotive damper technology, specifically a vehicle internal and external circulation damper. Background Technology

[0002] Air conditioning is a crucial component of a vehicle, creating a comfortable environment inside during hot summer days or cold winters. The air damper is an important part of the automotive air conditioning system. Currently, the air damper and connecting rod of automotive air conditioning systems are manufactured separately, with a rotating shaft integrally formed at both ends of the damper. The damper is then connected to the car via the rotating shaft. As the automotive air conditioning system ages, the connection between the damper and the rotating shaft can easily loosen due to prolonged friction. This can affect the sealing effect of the damper during use and may cause abnormal noises while the vehicle is in motion, affecting the driving experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an in-vehicle and out-of-vehicle air circulation damper, which solves the problem that traditional automotive dampers tend to loosen at the damper and shaft connection as the car's air conditioning system ages. This prevents the damper's sealing performance from being affected during use and also prevents the vehicle from making abnormal noises while driving, thus affecting the driving experience.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an in-vehicle and out-of-vehicle circulating damper, comprising a damper frame, a canvas fixedly connected to the inner surface of the damper frame, mounting shafts fixedly connected to both ends of the damper frame, multiple sets of ball bearings embedded and rolled on the side surface of the mounting shafts, a protective sleeve covering the outer side of the ball bearings, the inside of the protective sleeve being filled with lubricant, a rubber ring fixedly connected to the outer surface of the protective sleeve, the rubber ring being interference-fitted with the mounting hole, and sealing components installed on both sides of the damper frame.

[0005] Preferably, the canvas has multiple pleats, and the ends of the pleats are fixedly fitted with reinforcing ribs, the two ends of which are fixedly connected to the inner surface of the damper frame.

[0006] Preferably, the sealing assembly includes an installation strip, which is fixedly connected to the side surface of the damper frame, and a magnetic strip is provided on the outer side of the installation strip.

[0007] Preferably, the cross-section of the mounting strip is T-shaped, and the interior of the magnetic strip has a mounting groove that matches the mounting strip.

[0008] Preferably, rubber strips are fixedly connected to both sides of the magnetic strip, and the rubber strips have an arc-shaped structure.

[0009] This utility model provides an in-vehicle and out-of-vehicle air circulation damper. Compared with the prior art, it has the following advantages: By using a rolling ball embedded in the side surface of the mounting shaft and a protective sleeve on the outside of the ball, which cooperates with the rubber ring on the outer surface of the protective sleeve, the problem of loosening at the damper and shaft connection of traditional automotive dampers is solved as the car air conditioning system ages. This avoids affecting the damper's sealing effect during use and prevents abnormal noises from the vehicle while driving, thus affecting the driving experience. Secondly, the magnetic strips connected to the two sides of the damper frame by mounting strips and the rubber strips on the side surfaces of the magnetic strips ensure a tight contact between the damper and the air duct when the damper is closed, further improving the damper's sealing performance.

[0012] 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.

[0013] Please see Figure 1-4 This utility model provides a technical solution: an in-vehicle and out-of-vehicle circulating damper, including a damper frame 1, a canvas 101 fixedly connected to the inner surface of the damper frame 1, mounting shafts 3 fixedly connected to both ends of the damper frame 1, multiple sets of ball bearings 303 embedded and rolled on the side surface of the mounting shafts 3, a protective sleeve 301 sleeved on the outer side of the ball bearings 303, the inside of the protective sleeve 301 filled with lubricant, a rubber ring 302 fixedly connected to the outer surface of the protective sleeve 301, the rubber ring 302 being interference-fitted with the mounting hole, and sealing components 2 installed on both sides of the damper frame 1.

[0014] As a technical optimization of this utility model, the canvas 101 is provided with multiple pleats, and the ends of the pleats are fixedly installed with reinforcing ribs 102. The two ends of the reinforcing ribs 102 are fixedly connected to the inner surface of the damper frame 1, which can improve the strength of the damper and prevent the damper from deforming or being damaged during use.

[0015] As a technical optimization of this utility model, the sealing component 2 includes an installation strip 201, which is fixedly connected to the side surface of the damper frame 1. A magnetic strip 203 is provided on the outer side of the installation strip 201 to improve the sealing performance of the damper.

[0016] As a technical optimization of this utility model, the cross-section of the mounting strip 201 is a T-shaped structure, and the magnetic strip 203 has an installation groove 204 that matches the mounting strip 201 inside, so that the magnetic strip 203 can be easily disassembled and replaced through the installation groove 204.

[0017] As a technical optimization of this utility model, rubber strips 202 are fixedly connected to both sides of the magnetic strip 203. The rubber strips 202 have an arc-shaped structure, which further improves the sealing performance of the damper.

[0018] In use, this utility model securely mounts the damper 1 into the mounting holes inside the vehicle via rubber rings 302 on the outer sides of the protective sleeves 301 at both ends. During installation, the rubber rings 302 are compressed and inserted into the mounting holes, thus improving the installation stability of the damper 1. When the damper 1 and canvas 101 are rotated, the protective sleeves 301 and ball bearings 303 remain stationary relative to the vehicle, while the mounting shaft 3 rotates via the ball bearings 303. The ball bearings 303 reduce friction between the mounting shaft 3 and the protective sleeves 301, preventing loosening due to wear. After rotation, the magnetic strip 203 adheres the side surface of the damper 1 to the vehicle's air duct, ensuring close contact between the rubber strip 202 and the vehicle's air duct, preventing gaps between the damper 1 and the air duct, and further improving the damper's sealing performance.
