Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1A-1B, the vehicle V has an interior I that includes vehicle interior components such as a dashboard IP, floor console FC, overhead console OC, door panels DP, and the like. The vehicle V also includes a ventilation system (e.g., for providing conditioned air for an air conditioning system and/or a heating system, etc.) that provides an airflow to the interior I through an air outlet device AV (e.g., mounted in a vehicle interior component).

As shown in fig. 2A to 2B, the air-out device AV according to the present invention includes a casing 10, and a front row blade assembly 20 and a rear row blade assembly 30 disposed inside the casing 10. The housing 10 provides an air inlet IN, an air outlet OT, and a passage connecting the air inlet IN and the air outlet OT. The air outlet device AV further includes a dial 40 disposed on the casing 10 near the air outlet OT to control the flow rate and direction of the air flow from the inlet IN connected to the ventilation system, the air flow passing through a passage IN the casing 10 and being guided through the front row blade assembly 20 and the rear row blade assembly 30 to achieve blowing IN the horizontal and vertical directions. Specifically, when the dial 40 is pivoted in a first direction (e.g., horizontal/left-right direction), the rear row blade group 30 is kept stationary, and the front row blade group 20 is rotated in the same direction with the dial 40 to adjust the wind direction in the vertical direction; when the dial 40 pivots about a second direction (e.g., vertical/up-down direction), the front row blade group 20 remains stationary, and the rear row blade group 30 rotates in the same direction with the dial 40 to adjust the wind direction in the horizontal direction; when the dial 40 is pressed in a third direction (e.g., a front-rear direction), the front row blade assembly 20 remains stationary, and the adjacent blades 301 of the rear row blade assembly 30 are driven to overlap end-to-end by the swing lever 413 (which will be described in detail later) of the dial 40 to prevent airflow from being closed by the air volume, or the adjacent blades 301 of the rear row blade assembly 30 are separated to allow airflow to be opened by the air volume. In the present embodiment, the air volume is turned off by pressing the dial knob 40, and turned on by pressing the dial knob 40 again, so that the dial knob 40 has a push-push function. It should be understood that it is also possible to close the air volume by pulling the dial 40 and open the air volume by pulling the dial 40 again.

As shown in fig. 2B, the front row blade assembly 20 includes a plurality of front row blades or horizontal blades 201, a follower blade 202, a connecting rod 203 and a bracket 204, wherein the follower blade 202 is connected between the housing 10 and the front row blades 201 to guide the airflow, all the front row blades 201 are connected by the connecting rod 203 to move synchronously, both left and right ends of each front row blade 201 are rotatably mounted on the bracket 204, respectively, and the connecting rod 203 is connected with (a first fork or horizontal fork 414 of) the dial knob 40, which will be described in detail later, to drive the front row blade assembly 20 to rotate by the dial knob 40.

As shown in fig. 2B, the rear row blade assembly 30 includes a plurality of rear row blades or vertical blades 301, a connecting rod 302, a bracket 303, a crank 304 and a crank connecting rod 305, wherein the plurality of rear row blades 301 are connected by the connecting rod 302 to move synchronously, the upper and lower ends of each rear row blade 301 are rotatably mounted on the bracket 303 respectively, and the leftmost rear row blade 301 is connected to (a second fork or vertical fork 406 of) the dial knob 40 by the crank 304 and the crank connecting rod 305 to drive the rear row blade assembly 30 to rotate by the dial knob 40.

As shown in fig. 2B and 3A, the knob 40 includes a handle 401, an outer ball 402, a retaining ring 403, a damper 404, an inner ball 405, a vertical fork 406, a cage 407, an outer ball cover 408, a lock block 409, a slider 410, a spring 411, a base 412, a rocker 413, a horizontal fork 414, and a lock lever 415. Outer ball 402 and outer ball cover 408 are fixedly attached and disposed about inner ball 405 to achieve a spherical fit. An outer ball 402 is disposed within the damper 404 and secures the damper 404 by a metal ring 403 to form a ball hinge in a ball cage 407. After passing through the outer ball 402, the handle 401 is fixedly connected to the lock block 409 passing through the inner ball 405. Specifically, the spline 4091 (see fig. 3C) of the lock block 409 is inserted into an open slot 4011 on the handle 401 to achieve synchronized movement of the lock block 409 and the handle 401. The slider 410 is mounted on the base 412 movably back and forth by a spring 411. The locking piece 409 is in interference fit with the slider 410 (see fig. 4B) to move back and forth with the slider 410, and has a freedom of deflection up and down, left and right with respect to the slider 410, so that when the toggle button is deflected up and down, left and right, the locking piece 409 is always abutted against the slider 410 to limit the slider 410 to be kept still. The swing link 413 is hinge-engaged with the slider 410 (see fig. 10B) to move forward and backward with the slider 410 while having a rotational degree of freedom with respect to the slider 410. As shown in fig. 3B, the vertical fork 406 is hinged to the inner ball 405 such that the vertical fork 406 can rotate relative to the inner ball 405. It should be understood that the hinges are presented herein by way of example only and not limitation. Returning to FIG. 2B, the vertical fork 406 is also connected to the trailing row of blades 30 via a rocker 413 to drive the trailing row of blades 30. As shown in fig. 3C, the horizontal fork 414 is hinged to the locking block 409 such that the horizontal fork 414 can rotate relative to the locking block 409 about a hinge axis extending in the up-down direction. It should be understood that the hinges are presented herein by way of example only and not limitation. Returning to fig. 2B, the horizontal fork 414 is also connected to the front row of blades 20 to drive the front row of blades 20. In addition, locking bar 415 has one end mounted to base 412 and the other end that cooperates with the heart-shaped slot of lock block 409 to define adjacent back row blades 301 to remain partially overlapped.

As shown in fig. 4A, when the handle 401 is in the neutral position, the front row of blades 201 is in the neutral position. As shown in fig. 4B, inner ball 405 includes a recess including first and

second groove bottoms

4051, 4052 extending across each other on the inner wall of inner ball 405, and when handle 401 is in the neutral position, spline 4091 of lock block 409 remains spaced apart from both first and

second groove bottoms

4051, 4052. It should be understood that the arrangement of the splines 4091 (see fig. 3C) and grooves may be reversed, i.e. grooves with groove bottoms extending across each other are provided on the lock block 409 and splines are provided on the inner ball 405. In addition, since the locking piece 409 is fixedly connected with the handle 401, the spline can also be arranged on the handle 401.

As shown in fig. 5A-5B, when the handle 401 is deflected upward, the handle 401 rotates the outer ball 402, and at the same time, the spline 4091 of the lock block 409 moves toward the first groove bottom 4051, the inner ball 405 remains stationary, so the vertical fork 406 connected to the inner ball 405 also remains stationary, and the rear row of blades 30 remains stationary. The upward deflection of the handle 401 also drives the lock block 409 to rotate downward, which in turn drives the horizontal fork 414 connected to the lock block 409 to swing downward together. The horizontal shifting fork 414 drives the connecting rod 203 to move downwards, the connecting rod 203 is connected with the rear end of the front row of blades 201, so that the connecting rod 203 pushes the front row of blades 201 to turn downwards around a front end rotating shaft, the function of adjusting the wind direction upwards is realized until the upper limit position is reached, and the spline at the moment is contacted with the first groove bottom 4051.

As shown in fig. 6A-6B, when the handle 401 is deflected downward, the handle 401 rotates the outer ball 402, and at the same time, the spline 4091 of the lock block 409 moves toward the second groove bottom 4052, the inner ball 405 remains stationary, and therefore the vertical fork 406 connected to the inner ball 405 also remains stationary, and the rear row of blades 30 remains stationary. The downward deflection of the handle 401 also causes the lock block 409 to rotate upward, which in turn causes the horizontal fork 414 connected to the lock block 409 to swing upward together. The horizontal shifting fork 414 drives the connecting rod 203 to move upwards, and the connecting rod 203 is connected with the rear end of the front row of blades 201, so that the connecting rod 203 pushes the front row of blades 201 to turn upwards around a front-end rotating shaft, thereby realizing the function of downwards adjusting the wind direction until reaching a lower limit position, and the spline at the moment is contacted with the second groove bottom 4052.

As shown in fig. 7A-7B, when the handle 401 is in the neutral position, the back row of blades 301 is in the neutral position.

As shown in fig. 8A-8B, when the handle 401 deflects to the left, the handle 401 drives the outer ball 402, the inner ball 405 and the vertical fork 406 to rotate together, the vertical fork 406 drives the oscillating bar 413 to rotate, the crank connecting rod 305 is hinged between the oscillating bar 413 and the crank 304, and the rear row of blades 301 rotate to the left along with the oscillating bar 413, so that the function of adjusting the wind direction to the left is realized until the left limit position is reached. Meanwhile, although the inner ball 405 rotates along with the handle 401 to drive the lock block 409 to rotate, the lock block 409 is hinged to the horizontal shifting fork 414, so that the shifting fork 414 is not driven by the rotation of the lock block 409, and the front row of blades 201 are kept still. It should be understood that in the embodiment where the horizontal fork 414 is not hinged to the lock block 409, since the horizontal movement of the horizontal fork 414 is small or has enough movement space, the movement of the horizontal fork 414 does not necessarily result in the movement of the front row blade 201, which may also keep the front row blade 201 still.

As shown in fig. 9A-9B, when the handle 401 deflects to the right, the handle 401 drives the outer ball 402, the inner ball 405 and the vertical fork 406 to rotate together, the vertical fork 406 drives the oscillating bar 413 to rotate, the crank connecting rod 305 is hinged between the oscillating bar 413 and the crank 304, and the rear blade 301 rotates to the right along with the oscillating bar 413, so that the function of adjusting the wind direction to the right is realized until the right limit position is reached. Meanwhile, although the inner ball 405 rotates along with the handle 401 to drive the lock block 409 to rotate, the lock block 409 is hinged to the horizontal shifting fork 414, so that the shifting fork 414 is not driven by the rotation of the lock block 409, and the front row of blades 201 are kept still.

Returning to fig. 7A, when the handle 401 is at the non-pressed intermediate position, the rear blade 301 is at the intermediate position, and the outlet device is in the fully opened state. At this time, as shown in fig. 10A to 10B, the front end of the lock lever 415 is located at the entrance of the heart-shaped groove (also referred to as labyrinth groove) of the lock block 409; as shown in FIGS. 10C-10D, the driving finger 4132 of the rocker 413 is located at an entrance of the driving track groove 4121 of the base 412, and the follower finger 4131 of the rocker 413 is located at the first linear section 4061a of the follower track groove 4061 of the vertical fork 406 extending in the front-rear direction. It should be understood that the driving track groove is not necessarily disposed on the base 412 of the dial 40, and the driving track groove may be disposed on the housing 10 of the wind outlet device when the housing 10 (see fig. 2B) of the wind outlet device is integrally formed with the base 412 (see fig. 2B) of the dial 40.

By pressing the handle 401, the front end of the lock lever 415 enters the heart-shaped groove of the lock block 409 from the entrance (i.e. the lock lever 415 is engaged with the heart-shaped groove) until reaching the locking position as shown in fig. 11B-11C, and at the same time, the driving pointer 4132 of the oscillating lever 413 enters the broken line segment until entering the straight line segment 4121A extending in the front-rear direction of the driving track groove 4121 of the base 412 as shown in fig. 11D-11E, and the follower pointer 4131 of the driving oscillating lever 413 enters the broken line segment until entering the second straight line segment 4061B extending in the front-rear direction of the follower track groove 4061 of the vertical fork 406 as shown in fig. 11D-11E, so that the adjacent blades 301 of the rear row of blades 30 are driven to overlap end-to end, and as shown in fig. 11A, the air outlet device is in the closed state. It will be appreciated that the provision of the fore and aft extending slot in the horizontal fork 414 allows movement independent of the front row of vanes 20 during this pressing process, i.e. the front row of vanes 201 remains stationary during the pressing process.

When the handle 401 is pressed again, the front end of the lock bar 515 returns from the locking position along the other side of the heart-shaped groove to be unlocked (i.e. the lock bar 415 is separated from the heart-shaped groove), and similarly, the overlapped rear row blades 301 are separated to allow the airflow to pass through by the rotation of the swing rod 413, and the air volume is opened, so that the air outlet device is in an open state.
