Description

Technical Field

[0001] The utility model relates to the field of automobile air-conditioning dampers, in particular to a blowing surface defrosting damper for automobile air-conditioning. Background Art

[0002] The defrost damper of the car air conditioner is a key component in the car air conditioning system. It is mainly used to control the air flow and distribution. When the front windshield of the car is frosted, the defrost damper will be activated to guide the warm air to flow to the windshield to quickly remove the frost, ensure the driver's clear vision, and improve driving safety.

[0003] When frost appears on the side windows of the car, it is necessary not only to open the front windshield side air outlet door to blow air, but also to adjust the blowing direction of the left and right side air outlet doors of the car air conditioner, and cooperate with the front windshield side air outlet door to guide the warm air to flow to the side front and rear windows to quickly remove the frost and ensure a clear view of the side vision and rearview mirror;

[0004] However, the existing side-blowing defrost damper cannot concentrate the air flow when adjusting the blowing direction. For example, when defrosting, the side air outlet needs to be adjusted to one side. At this time, the wind direction cannot be concentrated, and some air cannot be blown to the side windows (such as the attached Figure 6 As shown in the figure), the defrosting speed is slow. For example, when the temperature inside the car is high and needs to be cooled by blowing on the face, the cold air cannot be concentrated and delivered to the facial area. If you choose to increase the wind speed, it will not only increase energy consumption but also increase the noise inside the car. Utility Model Content

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The embodiment of the present application provides a defrosting damper for a blowing surface of an automobile air conditioner, which solves the problem that the existing defrosting damper for a side blowing surface cannot concentrate the air flow direction when adjusting the blowing direction. Figure 6 As shown, the defrosting speed is slow. If you choose to increase the wind speed, it will not only increase energy consumption but also increase the noise inside the car. When in use, it is possible to concentrate the airflow to the side windows or facial area.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figure 1-Figure 5A defrost damper for a car air conditioner comprises an outer frame 1, wherein the outer frame 1 is provided with a plurality of upper and lower guide vanes 2 evenly distributed from top to bottom; a control panel 4 and a control panel 2 6 are provided in the outer frame 1, a plurality of left and right guide vanes 5 are provided at the bottom of the control panel 4, and a left and right guide vane 2 7 having the same number as the left and right guide vanes 5 is provided at the bottom of the control panel 2 6; a connecting mechanism is provided at the left end of the control panel 4, and the control panel 4 is connected to the right end of the control panel 2 6 through the connecting mechanism, and a linkage mechanism is provided on the upper and lower guide vanes 2, and the linkage mechanism is connected to the control panel 4.

[0034] The guide vanes for controlling the left and right wind directions are controlled separately by control panel 1 4 and control panel 2 6, and the left and right guide vanes 1 5 or the left and right guide vanes 2 7 can be controlled to be closed separately. This arrangement can concentrate the airflow and deliver it to the side windows or facial area, avoiding the problem of air flow dispersion during defrosting or blowing on the face.

[0035] Reference Figure 3 and Figure 4 The connecting mechanism includes a connecting rod 10 and a connecting head 11, one end of the connecting rod 10 is arranged at the left end of the control board 1 4, and the other end of the connecting rod 10 is connected to the connecting head 11. A connecting groove 12 is provided on the right end surface of the control board 2 6, and the connecting head 11 and the connecting rod 10 are both arranged in the connecting groove 12.

[0036] Such an arrangement can provide a certain range of independent movement for the control board 4. When the connector 11 moves in the connection slot 12, the position of the control board 4 in the outer frame 1 and the use status of the left and right guide plates 5 can be adjusted independently.

[0037] Reference Figure 4 The connecting groove 12 is a trapezoidal groove whose groove width is smaller than the groove bottom width, and the diameter of the connecting head 11 is larger than the groove width of the connecting groove 12.

[0038] Such a configuration can provide a certain range of flexible movement for the connector 11. When the connector 11 moves to the notch of the connecting groove 12, it will be stuck and stop moving. If the control board 14 continues to move, the control board 14 can be pulled by the connecting rod 10 and the connector 11 to move together with the control board 2 6.

[0039] Reference Figure 2 and Figure 4 The linkage mechanism includes a paddle 3, which is hollow and sleeved in the middle of the upper and lower guide plates 2. The top of the paddle 3 is connected to a transmission part 14, and a notch for the transmission part 14 to rotate is provided on one side of the control board 4 close to the upper and lower guide plates 2.

[0040] This arrangement allows the paddle 3 to move flexibly on the upper and lower guide plates 2, which can not only drive the upper and lower guide plates 2 to swing up and down, but also restrain the control board 4 from moving left and right on the inner surface of the outer frame 1, thereby linking the left and right guide plates 1 5 and the left and right guide plates 2 7 to swing left and right. The two ends of the transmission part 14 are respectively rotatably connected to the paddle 3 and the control board 4. The purpose of this arrangement is that when the paddle 3 swings up and down, it will not drive the control board 4 to swing.

[0041] Reference Figure 1 and Figure 4 , the transmission part 14 adopts a telescopic rod.

[0042] The transmission part 14 can also be made of a rubber strip, and the telescopic rod can provide a certain displacement gap when the paddle 3 swings up and down, and will not drive the control board 4 to swing.

[0043] Reference Figure 3 The bottom of the control board 1 4 and the control board 2 6 are provided with through holes 8 having the same number as the left and right guide plates 1 5 and the left and right guide plates 2 7, and the top of each left and right guide plate 1 5 and the left and right guide plate 2 7 is connected with a swing rod 9, and the swing rod 9 is arranged in the through hole 8 at the corresponding position.

[0044] This arrangement is to drive the connecting rod 10 and the left and right guide plates 1 5 or the left and right guide plates 2 7 to rotate around the rotating shaft 13 when adjusting the position of the control plate 1 4 or the control plate 2 6 .

[0045] Reference Figure 2 A square groove 15 is formed on the inner wall of the outer frame 1 , and the left end of the control panel 2 6 is arranged in the square groove 15 .

[0046] This arrangement can improve the stability of the control board 2 6 during translation.

[0047] Reference Figure 2 , Figure 3 and Figure 4 The tops of the plurality of left and right guide plates 1 5 and the plurality of left and right guide plates 2 7 are connected with a rotating shaft 13 , and the top ends of the plurality of rotating shafts 13 are arranged on the inner top wall of the outer frame 1 .

[0048] Such an arrangement can utilize the rotating shaft 13 to improve the rotation stability of the left and right guide plates 1 5 or the left and right guide plates 2 7 in the outer frame 1 .

[0049] During use, by moving the paddle 3, the paddle 3 translates left and right outside the upper and lower guide plates 2, and the paddle 3 uses the transmission part 14 to transmit the moving force to the control board 4, and the control board 4 drives the connecting rod 10 and the connecting head 11 in the connecting groove 12, and the connecting head 11 moves from the notch of the connecting groove 12 to the bottom of the groove. In this movement process, the thrust of the movement will not be transmitted to the control board 6. At this time, the positions of the control board 6 and the left and right guide plates 27 are inconvenient. The control board 4 pushes the connecting rods 10 on the multiple left and right guide plates 5, and the connecting rods 10 drive the left and right guide plates 5 to rotate with the rotating shaft 13 as the axis. Several left and right guide plates 5 close the right side area in the outer frame 1, that is, when defrosting the opposite side window, the wind blowing on the surface can be intercepted and diverted to the defrosting area, and the hot air blown out from the car air conditioner is blown out to the side window surface by the left and right guide plates 27, as shown in the attached figure. Figure 5 As shown, when the paddle 3 is pulled in the opposite direction, when the connecting head 11 moves to the slot position, it will be stuck and stop moving. If the control board 4 continues to be moved, the control board 4 can be pulled by the connecting rod 10 and the connecting head 11 to move the control board 2 6 together, so that the left and right guide plates 1 5 can be opened, and at the same time, the left and right guide plates 2 7 can be stacked and the left area in the outer frame 1 can be closed. That is to say, when the wind is blowing on the face, the wind blowing toward the side window can be stopped and diverted to the blowing face area.

[0050] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0051] By separately controlling the guide vanes that control the left and right wind directions by control panel 1 4 and control panel 2 6, the left and right guide vanes 1 5 or the left and right guide vanes 2 7 can be controlled to be closed separately. This arrangement can concentrate the airflow and deliver it to the side windows or facial area, avoiding the problem of air flow dispersion during defrosting or blowing on the face.

[0052] By concentrating the air flow, the defrosting speed is faster when the same wind speed is selected, which can reduce the energy consumption of the car air conditioner and reduce the noise inside the car to a certain extent.
