[0027] It should be further understood that the term "and / or" used in the specification and the following claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0028] Please refer to Figures 1 to 5 As Figure 1 and Figure 2 The embodiment of the present application provides a hand and automatic air outlet assembly device, which comprises a shell 1, a blade group 2, a motor 3, a blade friction plate 4 and a motor friction plate 5; the blade group 2 is rotatably connected to the shell 1; the motor 3 is fixedly connected to the shell 1; the blade friction plate 4 is fixedly connected with the blade group 2, the motor friction plate 5 is drivingly connected with the motor 3, the blade friction plate 4 and the motor friction plate 5 are tightly butt-jointed; the driving force of the motor 3 to the motor friction plate 5 is less than or equal to the static friction force between the blade friction plate 4 and the motor friction plate 5, so that when the motor 3 drives the motor friction plate 5 to rotate, the blade friction plate 4 and the motor friction plate 5 are relatively stationary, so as to drive the blade group 2 to rotate and swing; when the blade group 2 is manually adjusted, the force transmitted to the blade friction plate 4 is greater than the static friction force between the blade friction plate 4 and the motor friction plate 5, so that the blade friction plate rotates relative to the motor friction plate 5.

[0029] In the embodiment, the hand-automatic integrated air outlet assembly device is installed in the passenger compartment of the automobile, and is used for air supply and refrigeration in the passenger compartment in combination with the air conditioning system. Specifically, the hand-automatic integrated 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 1 is the main structure of the hand-automatic integrated air outlet assembly device, and has a cavity inside. An air outlet 11 is formed at the front end of the cavity, and the front end and the rear end of the cavity are connected. 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 1 is fixedly connected to the side wall, top or center control panel of the passenger compartment. The vane group 2 is rotatably arranged in the cavity of the shell 1. Specifically, the vane group 2 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 1. 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 group 2 has a certain width, when the vane group 2 rotates and faces a certain direction, the air generated by the air conditioning system from the rear end of the shell 1 can be guided by the vane group 2 and fixedly supplied in one direction.

[0030] Therefore, the hand-automatic integrated air outlet assembly device has an electrically adjusted and manually adjusted air supply mode. In the electrically adjusted air supply mode, the hand-automatic integrated air outlet assembly device has a circulating air supply mode and a concentrated air supply mode. In the circulating air supply mode, in order to achieve uniform air supply at each position in the passenger compartment, the vane group 2 is driven by the motor 3, the motor friction plate 5 and the vane friction plate 4 to reciprocate and rotate, thereby achieving automatic air sweeping. In the concentrated air supply mode, in order to achieve concentrated air supply in a certain area of the passenger compartment, the vane group 2 is driven by the motor 3, the motor friction plate 5 and the vane friction plate 4 to rotate to a certain direction, and the motor 3 stops working, thereby achieving concentrated air supply.

[0031] Specifically, the driving force of the motor 3 on the motor friction plate 5 can be ensured to be less than or equal to the friction force between the motor friction plate 5 and the vane friction plate 4 by adjusting the power of the motor 3 and the size of the friction force between the motor friction plate 5 and the vane friction plate 4. The motor 3 can be electrically connected and communicatively connected with the main control unit in the automobile, so that the passenger can adjust the rotating direction and rotating angle of the output shaft of the motor 3 in a directional and quantitative manner by operating the virtual control button or the physical control button connected with the CCM (Chassis Control Module) in the automobile, so as to rotate and adjust the vane group 2 to a certain direction of air sweeping state.

[0032] In the manual adjustment air supply mode, the hand self-adjusting air outlet assembly device has a concentrated direction air supply mode. By applying a driving force to the blade group 2, the driving force is transmitted to the blade friction plate 4 through the blade group 2, so that the driving force received by the blade friction plate 4 fixedly connected with the blade group 2 is greater than the friction force between the blade friction plate 4 and the motor friction plate 5, and the blade group 2 and the blade friction plate 4 are driven to rotate. When the blade group 2 rotates to the direction satisfied by the user, the driving force applied to the blade group 2 is stopped, and the friction force between the blade friction plate 4 and the motor friction plate 5 keeps the blade friction plate 4 and the blade group 2 in the direction, realizing the manual adjustment of the concentrated air supply. When in the electrically adjusted concentrated air supply mode, if the passenger is not satisfied with the direction of the air supply adjusted by the electrically adjusted mode, for example, the preset angle of the electrically adjusted mode cannot meet the demand of the passenger. Or the passenger cannot make further electrically adjusted, for example, the button for electrically adjusted is located on the main machine in the cockpit, and the hand self-adjusting air outlet assembly device is located in the rear seat cabin area, and the rear passenger can directly adjust the direction of the blade group 2 by hand. The blade group 2 receives the driving force from the hand of the passenger, and when the driving force transmitted to the blade friction plate 4 is greater than the friction force between the blade friction plate 4 and the motor friction plate 5, the blade group 2 and the blade friction plate 4 are driven to rotate to the direction satisfied by the passenger. The driving force applied to the blade group 2 is stopped, and the friction force between the blade friction plate 4 and the motor friction plate 5 keeps the blade friction plate 4 and the blade group 2 in the direction, realizing the manual adjustment in the air supply mode of the electrically adjusted mode.

[0033] In this way, the hand self-adjusting air outlet assembly device integrates the air supply modes of electrically adjusted and manually adjusted, can meet the demand of passengers with different use habits, and reduces the learning cost of passengers. The transmission structure of the blade friction plate 4 and the motor friction plate 5 is simple, which can reduce the production and installation cost.

[0034] For reference Figure 3 , Figure 4 and Figure 5 In an embodiment, the blade group 2 includes a front row blade group 21 located at the front end of the shell 1 and a rear row blade group 22 located inside the shell 1.

[0035] In the embodiment, the first stepper motor 31 independently drives the front row of blade groups 21 located at the front end of the shell 1, i.e., the front end of the shell 1 towards the space for passengers inside the passenger cabin, and each blade in the front row of blade groups 21 can be arranged in a horizontal direction to achieve up-down air sweeping when swinging. The rear row of blade groups 22 is arranged inside the cavity of the shell 1 and located on the side of the front row of blade groups 21 away from the front end of the shell 1. The rear row of blade groups 22 is arranged perpendicularly to the front row of blade groups 21, and thus, when the front row of blade groups 21 performs up-down air sweeping in the vertical direction, the rear row of blade groups 22 can perform left-right air sweeping in the horizontal direction, and the front row of blade groups 21 and the rear row of blade groups 22 cooperate with each other to achieve air supply in any direction. It can be understood that the front row of blade groups 21 can also perform left-right air sweeping in the horizontal direction, and the rear row of blade groups 22 can perform up-down air sweeping in the vertical direction.

Specifically, the first stepper motor 31 is arranged on the first outer side wall 12 of the shell 1, and the second stepper motor 32 is arranged on the second outer side wall 13 of the shell 1 adjacent to the outer side wall where the first stepper motor 31 is arranged, and the second outer side wall 13 is adjacent to the first outer side wall 12.

[0054] It should be noted that the front row connecting rod 211 is rotatably connected to each front blade 212, which means that the front row connecting rod 211 can swing with any front blade 212, thereby driving other front blades 212 to swing.

[0055] Further referring to Figure 3 In an embodiment, the rear row blade group 22 includes a rear row connecting rod 221 and a plurality of parallel rear blades 222; both ends of each rear blade 222 are rotatably connected to the two side walls inside the shell 1; each rear blade 222 is rotatably connected to the rear row connecting rod 221, and the rear row connecting rod 221 is perpendicular to each rear blade 222; and at least one end of the rear blade 222 is inserted into the second insertion hole of the second insertion part 8. When the second stepping motor 32 drives the rear row blade friction plate 42 to rotate, the rear row blade friction plate 42 drives each rear blade 222 to rotate and swing simultaneously through the rear row connecting rod 221. When any rear blade 222 is manually adjusted, each rear blade 222 is driven to rotate and swing simultaneously through the rear row connecting rod 221.

[0056] In the embodiment, one end of the middle rear blade 222 is preferably inserted into the second insertion hole to reduce the complexity of the structure. In addition to the rear blade 222 inserted into the second insertion hole, both ends of each of the remaining rear blades 222 are provided as protruding rotating shafts, and a plurality of sets of shaft holes are respectively formed in the two opposite side walls inside the shell 1.

By providing the rear row connecting rod 221, the rear blades 222 are connected as a whole, and when the air outlet direction of a single rear blade 222 is manually or electrically changed, the rear row connecting rod 221 can ensure that the rear blades 222 are simultaneously adjusted.

[0057] It should be noted that the rear row connecting rod 221 is rotatably connected to each of the rear blades 222, which means that the rear row connecting rod 221 can swing with any rear blade 222, thereby driving other rear blades 222 to swing.

[0058] The embodiment of the utility model further provides a car, including air conditioning system and the hand -self -integrated air outlet assembly device provided by above -mentioned embodiment, hand -self -integrated air outlet assembly device and air conditioning system intercommunication.

[0059] Specifically, the hand -self -integrated air outlet assembly device is arranged in the cabin of the car, so that the air flow formed by the air conditioning system can be blown into the cabin of the car from the hand -self -integrated air outlet assembly device, and the cabin of the car is heated, refrigerated or ventilated.

[0060] In summary, in the hand -self -integrated air outlet assembly device, the motor drives the motor friction plate to rotate, and the motor friction plate and the blade friction plate are driven to rotate by the static friction force between the motor friction plate and the blade friction plate, the blade friction plate is synchronously driven to rotate and swing by the blade group, and the electric adjustment of the circulating air supply or the concentrated air supply of the blade group is realized. When the passenger manually adjusts, the motor is locked, the blade group is driven by the driving force from the passenger's hand, the driving force is transmitted to the blade friction plate, the static friction force between the motor friction plate and the blade friction plate is less than the driving force received by the blade friction plate, and the blade friction plate moves relative to the motor friction plate. Thus, the functions of manual adjustment and electric adjustment are integrated in one device, and the needs of passengers with different habits are met.

[0061] Further, if the passenger manually adjusts the blade group in the process of motor rotation, i.e. the electrically-regulated circulating air supply mode, as long as the force transmitted to the blade friction sheet is greater than the static friction force between the motor friction sheet and the blade friction sheet, the blade friction sheet will move relative to the motor friction sheet, avoiding damage to the motor.

[0062] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
