Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle accessories, and more specifically, particularly relates to a variable air outlet structure for a vehicle air conditioner. Background Art

[0002] Car air conditioners are basically equipped on all cars. The air vents of the car air conditioner are distributed in upper and lower channels to receive wind on the upper body and legs of passengers. However, in the existing air-conditioning ducts, the blades arranged at the air outlet are manually controlled to open and close, thereby controlling the air outlet switch. When the arranged blades close the air outlet, there are assembly errors and injection molding process errors at the overlap between the blades, resulting in air leakage, and the leakage amount does not meet the standard. At the same time, the arranged blades are small and light, and when the damper is closed, it is easy to produce howling.

[0003] Therefore, in view of this, research and improvement are conducted on the existing structure and deficiencies, and a vehicle-mounted air conditioner variable air outlet structure is provided, in order to achieve a purpose with greater practical value. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a vehicle-mounted air conditioner variable air outlet structure to solve the problems of air leakage and howling at the air conditioner air outlet.

[0005] The purpose and effect of the variable air outlet structure of a vehicle air conditioner of the present invention are achieved by the following specific technical means:

[0006] A variable air outlet structure for a vehicle air conditioner comprises a shell, one end of the shell is provided with an air outlet, an air guide frame is provided in the air outlet, the air guide frame divides the air outlet into a channel a and a channel b, an upper air plate is provided in the channel a, a lower air plate is provided in the channel b, both ends of the upper air plate and the lower air plate are rotatably connected to both sides of the air outlet, and one end thereof passes through the air outlet and is connected to a driving member;

[0007] The driving member includes a control disk, a motor is connected to the outer side of the control disk, an adjustment track is arranged on the inner side of the control disk, a second crank is arranged at the end of the upper wind plate, an upper plate shaft placed in the adjustment track is arranged on the second crank, a first crank is arranged at the end of the lower wind plate, a lower plate shaft placed in the adjustment track is arranged on the first crank, and the control disk rotates so that the upper plate shaft and the lower plate shaft both slide in the adjustment track and drive the upper wind plate and the lower wind plate to swing at a certain angle.

[0008] Furthermore, the adjustment track includes an upper plate channel and a lower plate channel, the upper plate shaft is clamped in the upper plate channel, and the lower plate shaft is clamped in the lower plate channel. The upper plate channel and the lower plate channel are both composed of three areas. The rotating control disk causes the area changes of the positions of the upper plate shaft and the lower plate shaft to occur simultaneously.

[0009] Further, the upper plate channel includes an adaptation part, a static part, and a second closing part connected in sequence, and the lower plate channel includes a first closing part, a transition part, and an opening part connected in sequence. When the upper plate shaft is clamped in the adaptation part, the lower plate shaft is correspondingly clamped in the first closing part.

[0010] Further, the static part, the opening part, and the first closing part are all arc-shaped grooves centered on the control disk rotating shaft, and the opening part and the first closing part have different radii.

[0011] Further, a fixing pin is provided on the control disk, and a chute feature is provided on the second crank. When the control disk is in the initial position, the fixing pin is clamped in the chute feature to realize the self-closure of the a-channel.

[0012] Further, the air guide frame is formed by fitting two air guide shells.

[0013] Further, a side frame is provided on the side of the housing beside the ventilation opening, the control disk is arranged inside the side frame, and the motor is installed outside the side frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The control disk is driven by the motor to rotate, and the adjustment track on the control disk rotates around the axis of the control disk. The upper plate shaft and the lower plate shaft clamped in the adjustment track are driven by the constraint of the adjustment track to drive the upper air plate and the lower air plate to swing in the corresponding a-channel and b-channel, thereby controlling the opening and closing of the a-channel and the b-channel. A single air plate blocks the air duct and works independently of the air outlet blades, reducing gas leakage and noise at the same time; and the track controls the swinging of the upper air plate and the lower air plate, increasing the cycle durability compared with the traditional drive and spring combination to control the swinging of the air plate.

[0016] 2. Through the arrangement of the upper plate channel and the lower plate channel on the control disk, during the rotation of the control disk, the upper plate shaft and the lower plate shaft will respectively pass through three regions, realizing four opening and closing modes jointly presented by the a-channel and the b-channel.

[0037] Embodiment:

[0038] As shown in the attached Figure 1 to the attached Figure 15 figures:

[0039] The present invention provides a variable air outlet structure for a vehicle-mounted air conditioner, including a housing 1. One end of the housing 1 is provided with a ventilation opening 2. A wind guide frame 5 is arranged in the ventilation opening 2. The wind guide frame 5 divides the ventilation opening 2 into an a-channel and a b-channel. As shown in Figure 1 and Figure 2 figures, the a-channel corresponds to the upper body air outlet of the passengers above the vehicle-mounted air conditioner, and the b-channel corresponds to the leg air outlet of the passengers below the vehicle-mounted air conditioner. In the prior art, blades arranged for adjusting the wind direction are provided at the air outlet;

[0040] An upper wind plate 7 is arranged in the a-channel, and a lower wind plate 6 is arranged in the b-channel. Both ends of the upper wind plate 7 and the lower wind plate 6 are rotatably connected to both sides of the ventilation opening 2. One end thereof passes through the ventilation opening 2 and is connected to a driving member. The driving member controls the swinging of the upper wind plate 7 and the lower wind plate 6 to realize the opening and closing of the a-channel and the b-channel;

[0041] The driving member includes a control disk 8. The outside of the control disk 8 is connected with a motor 3. A side frame 4 is arranged on the side of the housing 1 beside the ventilation opening 2. The control disk 8 is arranged inside the side frame 4, and the motor 3 is installed outside the side frame 4. The control disk 8 is rotated by driving the motor 3;

[0042] An adjustment track is provided inside the control panel 8. A second crank 71 is provided at the end of the upper air plate 7. An upper plate shaft 74 placed in the adjustment track is provided on the second crank 71. A first crank 61 is provided at the end of the lower air plate 6. A lower plate shaft 62 placed in the adjustment track is provided on the first crank 61. As Figure 2 and Figure 14 shown, the adjustment track includes an upper plate channel 82 and a lower plate channel 81. The upper plate shaft 74 is clamped in the upper plate channel 82, and the lower plate shaft 62 is clamped in the lower plate channel 81;

[0043] In this embodiment, the lower plate channel 81 surrounds the outer periphery of the upper plate channel 82. The upper plate channel 82 includes an adaptation part 821, a static part 822, and a second closing part 823 that are connected in sequence. The lower plate channel 81 includes a first closing part 814, a transition part 813, and an opening part 812 that are connected in sequence. In the initial state, the upper plate shaft 74 is clamped at the inner end of the adaptation part 821, and the lower plate shaft 62 is clamped at the end of the first closing part 814. At this time, the upper air plate 7 and the lower air plate 6 block the a and b channels, and the a and b channels are in a closed state. As Figures 2 to 4 shown.

[0044] During the counterclockwise rotation of the control panel 8, a total of three processes are experienced. First, in the first process, the upper plate shaft 74 is squeezed by the adaptation part 821, and the upper plate shaft 74 shifts to the starting end of the static part 822. During this process, the distance between the upper plate shaft 74 and the center of the control panel 8 increases. The movement of the upper plate shaft 74 is transmitted to the upper air plate 7 through the second crank 71, causing the upper air plate 7 to swing a certain angle to open the a channel; and during this process, the lower plate shaft 62 moves relatively within the first closing part 814. Since the first closing part 814 is an arc-shaped groove centered on the rotation axis of the control panel 8, the distance between the lower plate shaft 62 and the center of the control panel 8 remains unchanged at each position within the first closing part 814. Then the lower plate shaft 62 is stationary in space, and the lower air plate 6 is in a stationary state, and the b channel remains closed. As Figures 5 to 7 shown.

[0045] In the second process, as the control panel 8 continues to rotate, the upper plate shaft 74 moves relatively within the static part 822. The static part 822 is also an arc-shaped groove centered on the rotation axis of the control panel 8. Then the upper plate shaft 74 is stationary in space, and the upper air plate 7 is in a stationary state, and the a channel is in an open state; while the lower plate shaft 62 passes through the transition part 813 and reaches the starting end of the opening part 812, and the distance from the center of the control panel 8 becomes larger. The lower plate shaft 62 is squeezed away from the center of the control panel 8. The lower plate shaft 62 moves during this process and is transmitted to the lower air plate 6 through the first crank 61, causing the lower air plate 6 to swing a certain angle to open the b channel. At this time, both the a and b channels are open. As Figures 8 to 10 shown.

[0046] In the third process, the control disk 8 continues to rotate, and the lower plate shaft 62 moves relatively in the opening part 812. The opening part 812 is also an arc-shaped groove centered on the rotation axis of the control disk 8. The lower plate shaft 62 remains stationary in space, the lower air plate 6 is in a stationary state, and the b-channel is in an open state. The upper plate shaft 74 moves within the second closing part 823. The distance between the upper plate shaft 74 and the center of the control disk 8 becomes smaller. The upper plate shaft 74 is squeezed and moves a certain distance closer to the center of the control disk 8. The upper plate shaft 74 drives the upper air plate 7 to swing in the reverse direction through the second crank 71. At this time, the a-channel is closed again, and the b-channel remains open, as Figures 11 to 13 shown.

[0047] In this embodiment, a fixing pin 811 is provided on the control disk 8, and a chute feature 72 is formed on the second crank 71. When the control disk 8 is in the initial position, the fixing pin 811 is clamped in the chute feature 72, as Figure 14 and Figure 15 shown. During the rotation of the control disk 8 from the initial position, the fixing pin 811 moves with the control disk 8, and the fixing pin 811 slides within the chute feature 72, thereby driving the upper air plate 7 to swing, adding power to the initial swing of the upper air plate 7, and preventing the upper plate shaft 74 at the end of the upper air plate 7 from getting stuck in the adaptation part 821, which affects the opening and closing of the air outlet channel.

[0048] Among them, the air guide frame 5 is formed by fitting two air guide shells together, which is convenient for disassembling the housing 1 and the air guide frame 5, and thus convenient for replacing the upper air plate 7 and the lower air plate 6.

[0049] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.
