Description

Technical Field

[0001] The utility model relates to the technical field of automobile air conditioners, in particular to a damper adjustment control device. Background Art

[0002] The damper is a vital component in the automobile air-conditioning system. Its main function is to control and adjust the flow direction and flow rate of the air inside the car to meet the personalized needs of the driver and passengers for the temperature, wind direction and comfort inside the car. When the damper is adjusted, the opening and closing degree of the damper is usually controlled by the operation of the motor.

[0003] The damper is generally rotated, and the damper is rotated to the front of the evaporator or the heater channel to seal it, so that the hot or cold air can be adjusted. However, when the current damper adjustment control device is in use, when the motor drives the damper shaft to rotate too large an angle, it is easy to cause the damper shaft to break. The damper cannot stably form an effective seal for the hot or cold air duct, which will affect the cooling or heating effect of the air conditioner. For this reason, we provide a damper adjustment control device. Utility Model Content

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] As attached Figure 1 To Attachment Figure 4 As shown: a damper adjustment control device includes an air duct 1, and a damper assembly 2 is arranged inside the air duct 1. The damper assembly 2 includes a frame-shaped groove 201 opened on the inner wall of the air duct 1, and the inner wall of the frame-shaped groove 201 is slidably connected with a damper body 202, and the front of the damper body 202 is fixedly connected with a push rod 203, and a group of rollers 204 are installed at the top and the bottom of the damper body 202, and the outer side of each roller 204 is rollingly connected with the inner wall of the frame-shaped groove 201, and the push rod 203 can pull the damper body 202 to move inside the frame-shaped groove 201. When the damper body 202 moves, it will drive the roller 204 to roll inside the frame-shaped groove 201, which can prevent the damper body 202 from getting stuck in the frame-shaped groove 201, and can allow the damper body 202 to move smoothly, so that the damper body 202 can block and seal the cold air or hot air channel.

[0026] A linkage assembly 3 is installed on the upper surface of the air duct 1, and the linkage assembly 3 includes a pillar 301 fixedly connected to the upper surface of the air duct 1, and the top of the pillar 301 is rotatably connected to a rotating plate 302. A groove 303 is provided on the upper surface of the rotating plate 302, and the other end of the push rod 203 is slidably connected to the inner wall of the groove 303. When the rotating plate 302 rotates around the pillar 301, the push rod 203 inside the groove 303 will slide inside the groove 303, so that the rotating plate 302 can push the push rod 203 to move, thereby realizing the adjustment of the damper body 202.

[0027] In order to further enhance the stability of the rotating plate 302 when it rotates, the linkage assembly 3 also includes an annular groove 304 opened on the upper surface of the air duct 1, and the inner wall of the annular groove 304 is slidably connected to two stabilizing rods 305, and the top of each stabilizing rod 305 is connected to the bottom surface of the rotating plate 302. When the rotating plate 302 rotates, the stabilizing rod 305 will be driven to slide inside the annular groove 304, and the stabilizing rod 305 will form a supporting effect on the rotating plate 302, thereby enhancing the stability of the rotating plate 302 when it rotates.

[0028] Embodiment 2:

[0029] A pushing component 4 is installed on the upper surface of the air duct 1, and the pushing component 4 includes a motor 401 installed on the upper surface of the air duct 1, and the output end of the motor 401 is fixedly connected with a threaded rod 402, and the outer surface of the threaded rod 402 is threadedly connected with a slider 403, and the upper surface of the slider 403 is fixedly connected with a moving rod 404, and the other end of the moving rod 404 is slidably connected to the inner wall of the groove 303, and a threaded hole adapted to the threaded rod 402 is provided on one side of the slider 403, and the threaded rod 402 is threadedly connected to the threaded hole on the slider 403. When the motor 401 works, it can drive the slider 403 to move, and at the same time, the moving rod 404 will pull the rotating plate 302 to rotate, thereby realizing the above-mentioned push of the push rod 203, and the damper body 202 can be adjusted, replacing the traditional damper shaft rotation adjustment method.

[0030] Embodiment 3:

[0031] like Figure 3 As shown, the pushing component 4 also includes a stabilizing groove 405 opened on the upper surface of the air duct 1, and the inner wall of the stabilizing groove 405 is slidably connected with a stabilizing block 406, and the top of the stabilizing block 406 is connected to the bottom surface of the slider 403. When the slider 403 moves on the threaded rod 402, the slider 403 will drive the stabilizing block 406 to move inside the stabilizing groove 405, so that the slider 403 can be stabilized and the slider 403 can be prevented from rotating, so as to prevent the slider 403 from driving the moving rod 404 to separate from the groove 303.

[0032] Furthermore, in order to allow the slider 403 to slide smoothly, the right end of the threaded rod 402 is rotatably connected to a reinforcement plate 407, and the bottom end of the reinforcement plate 407 is connected to the upper surface of the air duct 1. The reinforcement plate 407 can be used to support the other end of the threaded rod 402, and when the threaded rod 402 rotates, it will be more stable, thereby allowing the slider 403 to slide smoothly.

[0033] Embodiment 4:

[0034] like Figure 4 As described, the inner wall of the air duct 1 is fixedly connected with a partition 5, and the front side of the partition 5 is fixedly connected with a sealing pad 6, and the front side of the sealing pad 6 is in contact with the back side of the damper body 202. The partition 5 can divide the air duct 1 into two parts, so that the cold air and the hot air can be transported separately, and when the damper body 202 is located on either side, the sealing pad 6 will contact with the damper body 202 for sealing, so as to avoid cross-mixing of hot and cold air.

[0035] The size of the damper body 202 is larger than the distance between the partition 5 and the inner wall of the air duct 1, and the size of the damper body 202 is larger than half the width of the air duct 1, which can ensure that one end of the damper body 202 after moving is sealed with the frame groove 201, and the other end can be located on the other side of the partition 5, thereby ensuring the sealing effect of the hot air duct or the cold air duct.

[0036] Working principle: When the damper body 202 is adjusted, the motor 401 is started, and the motor 401 drives the threaded rod 402 to rotate inside the slider 403, and the slider 403 moves on the threaded rod 402, and the slider 403 drives the moving rod 404 to move, and the moving rod 404 pushes the rotating plate 302 when it moves, and the rotating plate 302 rotates in a circle with the support 301 as a circle. At the same time, the moving rod 404 slides inside the groove 303, and the rotating plate 302 rotates to push the push rod 203, and the push rod 203 pulls the damper body 202 to move, so that the damper body 202 can be adjusted. When it is necessary to control the damper body 202 to move in the opposite direction, it is only necessary to control the motor 401 to rotate in the opposite direction, which can ensure that the damper body 202 is sealed to the hot air duct and the cold air duct, thereby ensuring the cooling or heating effect of the air conditioner.
