Description

TECHNICAL FIELD

[0002] In order to exchange air inside and outside the car, the air conditioner air outlet is usually installed in the car cabin to provide the function of improving the environment inside the cabin, such as refrigeration and air supply. The existing air conditioner air outlet includes a manually adjusted air outlet and an electrically adjusted air outlet. The blade air supply direction of the manually adjusted air outlet needs to be adjusted by the passenger manually, and only a single direction of air supply can be maintained after adjustment. The blade air supply direction of the automatically adjusted air outlet can be automatically adjusted by the motor through the press button, and the multi-directional circulating air sweeping under the drive of the motor can be realized. Compared with the manually adjusted air outlet, the automatically adjusted air outlet has higher automation and intelligence. However, due to the differences in age and use habits of passengers, the adjustment methods of the air outlet used by passengers of different age groups are completely different. For example, young passengers tend to use the electrically adjusted air outlet with high intelligence and automation to avoid distraction during manual adjustment. Elderly passengers and young passengers are not familiar with or accustomed to the adjustment method of the electrically adjusted air outlet, and they are used to directly manually adjusting the air outlet.

[0027] As shown in Figure 1 and Figure 2 The utility model discloses a hand -of -machine air outlet assembly device, including casing 10, vane group 20, motor 30, drive arm 40, track disc 50 and detection device 60, vane group 20 rotatablely connected to casing 10, motor 30 is fixedly connected to casing 10, drive arm 40 is provided with at least one contact 80, is equipped with arc track 70 on track disc 50, and contact 80 is embedded in arc track 70, and at least one stop point 90 is equipped on track disc 50, drive arm 40 is transmission connection with vane group 20, and track disc 50 is transmission connection with motor 30, or drive arm 40 is transmission connection with motor 30, and track disc 50 is transmission connection with vane group 20, detection device 60 is set up on vane group 20, and detection device 60 is electrically connected with motor 30, is used for the swing angle of vane group 20 is fed back to motor 30, when drive arm 40 and track disc 50 relatively rotate, contact 80 moves relative to arc track 70, when contact 80 and stop point 90 contact, track disc 50 rotates with drive arm 40, when motor 30 drives track disc 50 and drive arm 40 synchronous rotation, drive arm 40 drives vane group 20 to rotate swing to preset position, and detection device 60 feeds back the position signal of vane group 20 to the controller of motor 30, and the controller of motor 30 can control motor 30 reverse, to remove the contact of contact 80 and stop point 90, so that vane group 20 can be manually adjusted swing.

[0028] In the embodiment, the stop points 90 on the track disc 50 can be arranged in the arc-shaped tracks 70, and the hands-free and self-adjusting air outlet assembly device is installed in the passenger compartment of the automobile and used for air supply and refrigeration in the passenger compartment in combination with the air conditioning system. Specifically, the hands-free and self-adjusting air outlet assembly device can be installed on the side wall, top or center control panel of the passenger compartment of the automobile. The shell 10 is the main structure of the hands-free and self-adjusting air outlet assembly device, and the shell 10 has a cavity inside, an air outlet is formed at the front end of the cavity, and the front end and the rear end of the cavity are connected in communication, wherein the front end faces the space where the passengers in the passenger compartment are located, and the rear end is connected to the air conditioning system. The shell 10 is fixedly connected to the side wall, top or center control panel of the passenger compartment. The vane set 20 is rotatably arranged in the cavity of the shell 10. Specifically, the vane set 20 can include a plurality of parallel vanes, each vane has a vane body and a vane shaft, the vane shaft is fixedly connected to the cavity of the shell 10, the vane body corresponding to the vane shaft is rotatably connected to the vane shaft and can rotate along the vane shaft, and can swing (reciprocating rotation) within a certain angle range. Since each vane in the vane set 20 has a certain width, when the vane set 20 rotates and faces a certain direction, the air generated by the air conditioning system sent from the rear end of the shell 10 can be guided by the vane set 20 and fixedly sent in one direction.

[0029] Therefore, the hands-free and self-adjusting air outlet assembly device has air supply modes of electric adjustment and manual adjustment. In the air supply mode of electric adjustment, the hands-free and self-adjusting air outlet assembly device has a circulating air supply mode and a concentrated air supply mode. Taking the driving arm 40 in transmission connection with the vane set 20 and the track disc 50 in transmission connection with the motor 30 as an example, in the circulating air supply mode, in order to realize uniform air supply at each position in the passenger compartment, the vane set 20 is driven by the motor 30, the track disc 50 and the driving arm 40 and reciprocatingly rotated to realize automatic air sweeping. In the concentrated air supply mode, in order to realize concentrated air supply in a certain area in the passenger compartment, the vane set 20 is driven by the motor 30, the track disc 50 and the driving arm 40 and rotated to a certain angle, the motor 30 does not drive the vane set 20 to rotate, and the vane set 20 is kept at the angle to realize concentrated air supply.

[0030] Specifically, taking the centralized air supply mode as an example, the motor 30 drives the track disc 50 to rotate, so that the arc-shaped track 70 on the track disc 50 and the stop point 90 in the arc-shaped track 70 rotate relative to the contact point 80 of the driving arm 40. Since the contact point 80 of the driving arm 40 is embedded in the arc-shaped track 70 on the track disc 50, when the stop point 90 in the arc-shaped track 70 rotates by a certain angle in one direction, the contact point 80 on the driving arm 40 will contact the stop point 90 in the arc-shaped track 70, so that the driving arm 40 rotates in the same direction with the track disc 50, so that the blade group 20 is driven to rotate and swing by the motor 30, the track disc 50 and the driving arm 40. The detection device 60 detects the rotation angle of the blade group 20 to determine whether it swings to the preset position, which can be multiple to correspond to multiple rotation angles. To ensure that the user can adjust the angle of the blade group 20 according to his own needs when manually adjusting, and to ensure that the manual adjustment will not damage the motor 30, after the blade group 20 is electrically adjusted to rotate to the preset position, the detection device 60 feeds back this information to the controller of the motor 30, and the controller of the motor 30 controls the motor 30 to reverse, so as to release the contact between the contact point 80 of the driving arm 40 and the stop point 90 of the track disc 50. Even if the contact point 80 and the stop point 90 are spaced apart by a distance, in this way, the user can rotate the blade group 20 in the direction of the last electric adjustment by manually adjusting, or can rotate the blade group 20 in the opposite direction of the last electric adjustment.

[0031] In the circulating air supply mode, the preset position is the position of the blade group 20 when the circulating air supply is finished.

[0032] Specifically, the motor 30 can be controlled to reverse to rotate the track disc 50 to the initial position, in which the positional relationship between the stop point 90 of the track disc 50 and the contact point 80 of the driving arm 40 satisfies that the stop point 90 of the track disc 50 and the contact point 80 of the driving arm 40 are spaced apart by a distance, and no matter in which direction the user manually rotates the blade group 20, it can be rotated by a sufficient angle, that is, during the process of rotating the blade group 20 from the start to the limit position, the stop point 90 of the track disc 50 will not block the contact point 80 of the driving arm 40, and manual adjustment will not rotate the locked motor 30, so as to ensure that the motor 30 will not be damaged due to manual adjustment.

[0033] Specifically, the motor 30 can be electrically connected and communicated with a master control unit in the car interior, the master control unit can be a controller of the motor 30, and the detection device 60 can be electrically connected with the motor 30 by being electrically connected with the master control unit. The passenger can adjust the rotating direction and rotating angle of the output shaft of the motor 30 in a directional and quantitative manner by controlling the virtual control button or the physical control button connected with the CCM (Chassis Control Module, vehicle body control module) in the car interior, so as to rotate and adjust the blade group 20 to a blowing state in a determined direction at a preset position.

[0034] In the manual adjustment blowing mode, the manual-automatic air outlet assembly device has a concentrated direction blowing mode, the blade group 20 is driven to swing to a certain angle according to the rotating direction thereof by applying a driving force to the blade group 20, so as to realize manual adjustment of concentrated blowing. Since the track disc 50 is rotated to the initial position after the electric adjustment, if the user (passenger) is not satisfied with the blowing direction or angle during the manual adjustment, the manual adjustment can be performed again, and the motor 30 does not need to be worried about being damaged.

[0035] Similarly, in the electric adjustment concentrated blowing mode, if the passenger is not satisfied with the blowing direction of the electric adjustment, for example, the preset angle of the electric adjustment cannot meet the demand of the passenger. Or the passenger cannot perform further electric adjustment, for example, the button for performing the electric adjustment is located on the main machine in the cockpit, and the manual-automatic air outlet assembly device is located in the rear seat cabin area, so that the rear passenger can directly adjust the direction of the blade group 20 by hand.

[0036] Therefore, the manual-automatic air outlet assembly device integrates the electric adjustment and the manual adjustment blowing mode, can meet the demand of passengers with different use habits, reduces the learning cost of the passenger, the manual adjustment will not damage the motor 30 in the conversion process from the electric adjustment to the manual adjustment, and the user can use it with confidence; and the transmission structure of the track disc 50 and the driving arm 40 is simple, and the production and installation costs can be reduced.

[0037] It should be noted that the arc-shaped track 70 includes a general arc-shaped track 70 and a special arc-shaped track 70, and the special arc-shaped track 70 is a circular track. The circle is a special arc, that is, the arc has an arc degree of 2π.

[0038] Reference should also be made to Figure 2In one embodiment, in order to reduce the rotation stroke of the output shaft of the motor 30 during the electric adjustment, the number of the stop points 90 on the track disc 50 is set to one, and the number of the contact points 80 on the driving arm 40 is set to two, and the stop point 90 is arranged between the two contact points 80, so that during the electric adjustment, the contact point 80 on the driving arm 40 can be contacted by the stop point 90 on the track disc 50 as early as possible, so that the driving arm 40 can rotate together with the track disc 50.

[0039] Specifically, the distance from the stop point 90 to the two contact points 80 is the same when the track disc 50 and the driving arm 40 are in the initial position, i.e. when the blade group 20 and the output shaft of the motor 30 are in the initial position, so that during the electric adjustment, the motor 30 rotates the same angle regardless of the direction of rotation, avoiding uneven friction for a long time and reducing the service life of the motor 30.

[0040] It can be understood that in other embodiments, the number of the contact points 80 on one driving arm 40 can be set to one, and the number of the stop points 90 on one track disc 50 can be set to two.

[0041] It can be understood that in other embodiments, the number of the contact points 80 on one driving arm 40 can be set to one, and the number of the stop points 90 on one track disc 50 can be set to two. Figure 1 、 Figure 3 、 Figure 4 and Figure 6 In one embodiment, the blade group 20 includes a front row of blade groups 201 located at the front end of the shell 10 and a rear row of blade groups 202 located inside the shell 10; the rear row of blade groups 202 is perpendicular to the front row of blade groups 201, and the rotation swing axis of the rear row of blade groups 202 is perpendicular to the rotation swing axis of the front row of blade groups 201.

[0042] At least one of the front row of blade groups 201 and the rear row of blade groups 202 can be driven to swing by the motor 30 and manually adjusted to swing.

[0043] Specifically, the front row of blade groups 201 can be driven to swing by the motor 30 and manually adjusted to swing, or the rear row of blade groups 202 can be driven to swing by the motor 30 and manually adjusted to swing, or both the front row of blade groups 201 and the rear row of blade groups 202 can be driven to swing by the motor 30 and manually adjusted to swing.

[0044] In the embodiment, the front row of blade groups 201 is arranged at the front end of the cavity of the shell 10 towards the space where the passengers are located inside the passenger cabin, and each blade in the front row of blade groups 201 can be arranged in the horizontal direction to achieve up and down air sweeping when swinging. The rear row of blade groups 202 is arranged inside the cavity of the shell 10 and is located on the side of the front row of blade groups 201 away from the front end of the shell 10. The rear row of blade groups 202 is arranged perpendicularly to the front row of blade groups 201, and thus, when the front row of blade groups 201 performs up and down air sweeping in the vertical direction, the rear row of blade groups 202 can perform left and right air sweeping in the horizontal direction, and the front row of blade groups 201 and the rear row of blade groups 202 cooperate with each other to achieve air supply in any direction. It can be understood that the front row of blade groups 201 can also perform left and right air sweeping in the horizontal direction, and the rear row of blade groups 202 can perform up and down air sweeping in the vertical direction.

[0045] For your reference Figure 1 and Figure 3 In the embodiment in which the front row of blade groups 201 and the rear row of blade groups 202 can be swung by the motor 30 and manually adjusted, the motor 30 includes a first stepper motor 301 and a second stepper motor 302; the first stepper motor 301 can drive the front row of blade groups 201 to swing, and the second stepper motor 302 can drive the rear row of blade groups 202 to swing; the first stepper motor 301 is fixedly connected to the first outer side wall 101 of the shell 10; the second stepper motor 302 is fixedly connected to the second outer side wall 102 of the shell 10, and the second outer side wall 102 is adjacent to the first outer side wall 101.

[0046] In the embodiment, the first stepper motor 301 and the second stepper motor 302 are independently connected to the shell 10 and supply power to the front row of blade groups 201 and the rear row of blade groups 202, respectively. Specifically, the first stepper motor 301 is arranged on the first outer side wall 101 of the shell 10, and the second stepper motor 302 is arranged on the second outer side wall 102 of the shell 10 adjacent to the outer side wall where the first stepper motor 301 is located, and the second outer side wall 102 is adjacent to the first outer side wall 101. When the hands-free air outlet assembly device is installed inside the passenger cabin of the vehicle, the inner cavity of the shell 10 and the blade groups 20 are exposed outside, and the outer side wall of the shell 10, the first stepper motor 301 and the second stepper motor 302 are all closed inside the inner wall of the passenger cabin and will not be exposed outside the passenger cabin.

[0047] For your reference Figure 1 , Figure 3 and Figure 5In one embodiment, the detection device 60 includes a first potentiometer 601 and a second potentiometer 602; the first potentiometer 601 is sleeved on the rotation shaft of the front blade group 201 and is electrically connected to the controller of the first stepper motor 301; the second potentiometer 602 is sleeved on the rotation shaft of the rear blade group 202 and is electrically connected to the controller of the second stepper motor 302.

[0048] In this embodiment, a first potentiometer is mounted on the rotating shaft of the front blade group 201. When the front blade group 201 rotates, the first potentiometer rotates with it, and the sliding contact 80 of the first potentiometer moves across its fixed resistor, thereby changing the resistance value. This change is fed back to the controller of the first stepper motor 301 via an electrical signal, thus determining whether the front blade group 201 has rotated to a preset position. A second potentiometer 602 is mounted on the rotating shaft of the rear blade group 202. When the rear blade group 202 rotates, the second potentiometer 602 rotates with it, and the sliding contact 80 of the second potentiometer 602 moves across its fixed resistor, thereby changing the resistance value. This change is fed back to the controller of the second stepper motor 302 via an electrical signal, thus determining whether the rear blade group 202 has rotated to a preset position.

The contact point 80 of the front drive arm 401 is embedded in the arc-shaped track 70 of the front track disk 501. When the first stepper motor 301 drives the front track disk 501 to rotate synchronously with the front drive arm 401, the front drive arm 401 drives the front blade assembly 201 to rotate and swing to a preset position. The first potentiometer 601 feeds back the position signal of the front blade assembly 201 to the controller of the first stepper motor 301. The controller of the first stepper motor 301 can control the first stepper motor 301 to reverse, so as to release the contact point of the front drive arm 401 from the stop point of the front track disk 501, so that the front blade assembly 201 can be manually adjusted and swung.

[0050] In the embodiment, the front row track disc 501 is in transmission connection with the first stepping motor 301, so that when the first stepping motor 301 adjusts the front row blade group 201, the first stepping motor 301 drives the front row track disc 501 to rotate, thereby driving the arc-shaped track 70 on the front row track disc 501 and the stop point 90 in the arc-shaped track 70 to rotate. After the stop point 90 contacts any contact point 80 of the front row driving arm 401, the front row driving arm 401 rotates with the front row track disc 501. Since the front row driving arm 401 is in transmission connection with the front row blade group 201, the front row blade group 201 is driven to rotate by the front row blade group 201. In the electrically adjusted central air supply mode, when the front row blade group 201 rotates to a preset position, i.e., a preset angle, the first potentiometer 601 feeds back the position information of the front row blade group 201 to the controller of the first stepping motor 301. The controller of the first stepping motor 301 controls the first stepping motor 301 to reverse, so as to restore the front row track disc 501 to the initial position. At this time, the stop point 90 of the front row track disc 501 is located between the two contact points 80 of the front row driving arm 401 and is spaced apart from the two contact points 80 by a distance. Therefore, when the user drives the front row blade group 201 to manually adjust the front row blade group 201 after this time, the front row blade group 201 can drive the front row driving arm 401 to rotate, and the contact point 80 of the front row driving arm 401 will not contact the stop point 90 in the arc-shaped track 70 on the front row track disc 501. The user manually adjusts the front row blade and will not damage the first stepping motor 301.

When the second step motor 302 drives the rear row track disc 502 to synchronously rotate the rear row driving arm 402, the rear row driving arm 402 drives the rear row vane set 202 to rotate and swing to a preset position, the second potential meter 602 feeds back a position signal of the rear row vane set 202 to a controller of the second step motor 302, and the controller of the second step motor 302 can control the second step motor 302 to reverse, so as to release the contact of the rear row driving arm 402 from the stop point of the rear row track disc 502, so that the rear row vane set 202 can be manually adjusted and swung.

[0054] In the embodiment, the rear track disc 502 is in transmission connection with the second stepping motor 302, so that when the second stepping motor 302 adjusts the rear blade group 202, the second stepping motor 302 drives the rear track disc 502 to rotate, thereby driving the arc-shaped track 70 on the rear track disc 502 and the stop point 90 in the arc-shaped track 70 to rotate. After the stop point 90 contacts any contact point 80 of the rear driving arm 402, the rear driving arm 402 rotates with the rear track disc 502. Since the rear driving arm 402 is in transmission connection with the rear blade group 202, the rear blade group 202 is driven to rotate by the rear blade group 202. In the electrically adjusted central air supply mode, when the rear blade group 202 rotates to a preset position, i.e., a preset angle, the second potentiometer 602 feeds back the position information of the rear blade group 202 to the controller of the second stepping motor 302. The controller of the second stepping motor 302 controls the second stepping motor 302 to reverse, so that the rear track disc 502 returns to the initial position. At this time, the stop point 90 of the rear track disc 502 is located between the two contact points 80 of the rear driving arm 402 and is spaced apart from the two contact points 80.
