[0024] Various specific embodiments of the present application will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "front", "rear", "up", "down", "left", "right", etc., are used in this application to describe various example structural parts and elements of the present application, these terms are used here only for the purpose of convenience of explanation and are determined based on the example orientations shown in the accompanying drawings. Since the embodiments disclosed in this application can be set in different directions, these directional terms are only for illustration and should not be regarded as limitations. Where possible, the same or similar figure numbers used in this application refer to the same parts.

[0025] Figure 1The figure is a schematic diagram of the air outlet 100 in the electric air adjustment mode of the embodiment of the present application. The air outlet 100 in the electric air adjustment mode includes a shell 101, a first set of blades 107, a driving device 103, an additional driving device 104, a first limiting device 110 and a manual operation part 109. It should be noted that the air outlet 100 in the manual air adjustment mode is similar in structure to the air outlet 100 in the electric air adjustment mode, and can be obtained by simply removing the driving device 103 and the additional driving device 104 from the air outlet 100 in the electric air adjustment mode. Figure 1 As shown, the housing 101 has an upward opening 113, and a receiving space 102 is formed in the housing 101. The first set of blades 107, the first limiting device 110, and the manual operation part 109 are all received at the opening 113 of the receiving space 102. The receiving space 102 includes a main body receiving space 111 and a handle receiving space 112. The handle receiving space 112 is located at one end of the housing 101 in the longitudinal direction.

[0026] The first stopper 110 is located between the main body accommodating space 111 and the handle accommodating space 112, and the main body accommodating space 111 and the handle accommodating space 112 are separated by the first stopper 110. The first stopper 110 is in the shape of a long rod and extends along the width direction of the housing 101. The length of the first stopper 110 is substantially the same as the width of the housing 101, so that the first stopper 110 can be arranged on the housing 101 across the width direction of the housing 101.

[0027] The first group of blades 107 is located in the main body accommodating space 111 and is the front row of blades of the air outlet 100. The first group of blades 107 includes a plurality of first blades 117. The plurality of first blades 117 are of the same shape and size and are all in the shape of long plates. Each first blade 117 extends along the length direction of the shell 101, and the length of each first blade 117 is approximately the same as the length of the main body accommodating space 111. The plurality of first blades 117 are parallel to each other and arranged side by side in the main body accommodating space 111, and the arrangement direction of the plurality of first blades 117 is consistent with the width direction of the shell 101. In this embodiment, the first group of blades 107 includes three first blades 117, and the three first blades 117 are spaced apart in the shell 101, dividing the opening 113 area of ​​the main body accommodating space 111 into four air outlet sub-areas. In other embodiments, the first group of blades 107 may also include other numbers of first blades 117, such as two, four, etc.

[0028] The manual operating portion 109 is located in the handle receiving space 112 and is movable within the handle receiving space 112 along a first moving direction and a second moving direction. In this embodiment, the first moving direction is the width direction of the housing 101, and the second moving direction is the length direction of the housing 101. The manual operating portion 109 is a cylindrical protrusion, and the user can access the manual operating portion 109 through the opening 113 of the housing 101. For the air outlet 100 in manual air adjustment mode, the user can manually drive the manual operating portion 109 to move within the hand receiving space 112 to adjust the air outlet direction of the air outlet 100 by controlling the movement of the manual operating portion 109.

[0029] The drive device 103 and the additional drive device 104 are disposed on the outside of the housing 101. The drive device 103 is disposed on a side surface extending along the width of the housing 101, while the additional drive device 104 is disposed on a side surface extending along the length of the housing 101. The coordinated action of the drive device 103 and the additional drive device 104 enables electrically adjustable airflow direction of the air outlet 100.

[0030] The air outlet 100 of the present application can be adapted to both a manual adjustment mode for the air outlet direction and an electric adjustment mode for the air outlet direction. For the air outlet 100 in the manual adjustment mode, the drive device 103 and the additional drive device 104 do not need to be installed on the outside of the shell 101. The user can adjust the air outlet direction of the air outlet 100 by directly controlling the manual operation part 109. For the air outlet 100 in the electric adjustment mode, it is necessary to Figure 1 As shown, a drive device 103 and an additional drive device 104 are installed on the outside of the housing 101, and the air outlet direction of the air outlet 100 is adjusted by the electric drive of the drive device 103 and the additional drive device 104. Except that the air outlet 100 in the electric air adjustment mode is equipped with a drive device 103 and an additional drive device 104 compared to the air outlet 100 in the manual air adjustment mode, the air outlet 100 in the manual air adjustment mode has the same structural composition and components as the air outlet 100 in the electric air adjustment mode. It is worth noting that although the air outlet 100 in the electric air adjustment mode is equipped with a manual operating unit 109, the manual operating unit 109 cannot control the air outlet direction of the air outlet 100. In other words, the air outlet 100 in the electric air adjustment mode can only be controlled by electricity after the drive device 103 and the additional drive device 104 are installed.

[0031] Figure 2 for Figure 1 The housing 101 is a perspective view of the housing 101. The housing 101 includes a housing body 114 and a housing boss 115. The housing boss 115 is a platform extending outward from the housing body 114. The housing body 114 has a main body receiving space 111 formed inside, and the housing boss 115 has a handle receiving space 112 formed inside. Figure 2 As shown, a first guide portion 201 is provided on the housing boss 115. The first guide portion 201 is a groove provided on the upper surface of the housing boss 115, and is used to limit the first moving direction of the manual operating portion 109 in the hand receiving space 112. In this embodiment, the first guide portion 201 extends along the width direction of the housing 101, and the first moving direction is the width direction of the housing 101. Since the housing boss 115 is located at one end of the length direction of the housing body 114 and is located in the top area of ​​the housing 101, the housing 101 reserves a spare area below the housing boss 115. Combined Figure 1 It can be seen that the driving device 103 can be installed in the empty area below the housing boss 115. This structural setting greatly optimizes the overall structure of the air outlet 100 and saves the installation space of the air outlet 100.

[0032] The housing 101 is provided with a stopper slot 116 at the intersection of the housing body 114 and the housing boss 115. The stopper slot 116 is located on the inner wall of the housing 101 and is used to securely install the first stopper 110. The housing 101 is provided with a fixing slot 118 at the other end of the housing 101 relative to the housing boss 115. The fixing slot 118 is located on the inner wall at the top position of the housing 101 and extends along the width direction of the housing 101 to facilitate the installation of the first set of blades 107.

[0033] Figure 3 for Figure 1 A three-dimensional view of the air outlet 100 after removing the housing 101. Figure 3 As shown, except Figure 1 In addition to the first set of blades 107, the driving device 103 and the additional driving device 104 shown in FIG, the air outlet 100 further includes a second set of blades 302 and a transmission assembly 303. Figure 1 The manual operating portion 109 and the first limiting member 110 shown in the figure are both components of the transmission assembly 303.

[0034] Each first blade 117 in the first set of blades 107 has its own first rotation axis 307, so that the three first blades 117 can rotate around the three first rotation axes 307 respectively. The first rotation axis 307 is located in its corresponding first blade 117, approximately at the upper end of the blade, and each first rotation axis 307 extends along the length direction of the corresponding first blade 117. The left end of the first set of blades 107 is provided with a first fixing member 310, and the right end is provided with a first limiting member 110. Figure 3As shown, the three first blades 117 are connected to the first fixing member 310 and the first limiting member 110 respectively through the three first rotating shafts 307. The left ends of the three first rotating shafts 307 are rotatably connected to the first fixing member 310, and the right ends of the three first rotating shafts 307 are rotatably connected to the first limiting member 110, so that the three first blades 117 are rotatably connected to the first fixing member 310 and the first limiting member 110 respectively. In other words, the first fixing member 310 and the first limiting member 110 are respectively located at the two ends in the length direction of the first group of blades 107, which can ensure the fixed connection of the first group of blades 107 without hindering the rotational movement of the three first blades 117 around the axis of their respective blades. Figure 1 、 Figure 2 and Figure 3 It can be seen that the first fixing member 310 and the first limiting member 110 are respectively disposed in the fixing member slot 118 and the limiting member slot 116 of the housing 101 to fix the first set of blades 107 on the housing 101 .

[0035] The first group of blades 107 is provided with a first linkage rod 313 on the lower side of its left end. The first linkage rod 313 is connected to the same side end of the width direction of the three first blades 117, so that the three first blades 117 can move in conjunction. In other words, as long as one of the three first blades 117 moves, the first linkage rod 313 can drive the other two blades to move together. Figure 3 In the illustrated state, the three first blades 117 are in a vertically downward extending position. When the three first blades 117 are driven externally to rotate about their respective first rotation axes 307, the three first blades 117 deviate from the vertical extension direction and are in an inclined position, and the angle of deviation of the three first blades 117 is always the same. The direction of rotation of the three first blades 117 is defined as the first rotation direction. Since the three first rotation axes 307 extend along the length of the housing 101, the first rotation direction is located in the plane of the width direction of the housing 101. To meet the wind direction requirements of the air outlet 100, the three first blades 117 can be rotated clockwise or counterclockwise according to their current position, and the three first blades 117 can be rotated about the axis to any suitable position.

[0036] The second set of blades 302 is located below the first set of blades 107 and forms the rear row of blades in the air outlet 100. Each second blade 312 in the second set of blades 302 has its own second rotation axis 317, enabling each second blade 312 to rotate about its own second rotation axis 317. In this embodiment, the second set of blades 302 includes four second blades 312. In other embodiments, other numbers of second blades 312 may be included, such as three or five. The four second blades 312 are of the same shape and size, each being plate-shaped. The second rotation axis 317 of each second blade 312 extends along the width of the housing 101, and the length of each second blade 312 extending in the direction of the second rotation axis 317 is approximately the same as the width of the main body receiving space 111, allowing the second set of blades 302 to be smoothly accommodated within the main body receiving space 111 of the housing 101. The four second blades 312 are arranged parallel to each other and side by side, with the arrangement direction of the four second blades 312 aligning with the length of the housing 101.

[0037] The second set of blades 302 is accommodated in the main body accommodation space 111 of the housing 101. Figure 2 As described above, the shell body 114 is provided with a plurality of blade mounting holes 127 on the two side surfaces extending along the length direction of the shell 101, respectively, for fixedly mounting the plurality of second blades 312. Corresponding to the four second blades 312 of this embodiment, the shell body 114 is provided with four blade mounting holes 127 on each side surface extending along the length direction of the shell 101. When the four second blades 312 are installed in the main body accommodating space 111, the two ends of the four second rotating shafts 317 are correspondingly inserted into the eight blade mounting holes 127 on the shell body 414, so that the four second blades 312 are rotatably connected to the shell 101. The above arrangement can ensure the fixed connection of the plurality of second blades 312 without hindering the rotational movement of the plurality of second blades 312 around their respective axes.

[0038] A second linkage rod 314 is provided on one side of the length direction of the four second blades 312. The second linkage rod 314 is connected to the end of the same side of the four second blades 312, so that the four second blades 312 can move in conjunction. In other words, as long as one of the four second blades 312 moves, the other three blades can be driven by the second linkage rod 314 to move together. Figure 3In the state shown, the four second blades 312 are arranged in a stacked manner, and each second blade 312 extends in a roughly horizontal direction. When the four second blades 312 rotate around their respective second rotation axes 317 due to external drive, the four second blades 312 can deviate from the horizontal extension direction respectively, and the deviation angles of the four second blades 312 are always the same. The direction of rotation of the four second blades 312 is defined as the second rotation direction. Since the second rotation axes 317 of the four second blades 312 extend along the width direction of the shell 101, the second rotation direction is located in the plane where the length direction of the shell 101 is located. In order to meet the wind direction requirements of the air outlet 100, the four second blades 312 can be rotated to any suitable position around the axis by choosing to rotate in a clockwise or counterclockwise direction according to the current position of the four second blades 312. At a certain moment, the four second blades 312 can be rotated to the following positions: Figure 3 The first set of blades 107 are shown in a position extending in the vertical direction.

[0039] When the air outlet 100 is in operation, air flows from the bottom of the housing 101 through the second set of blades 302 to the first set of blades 107. Both the first set of blades 107 and the second set of blades 302 guide the airflow through the air outlet 100, directly affecting the direction of the air flowing out of the air outlet 100. Because the first rotation axis 307 of the first blade 117 and the second rotation axis 317 of the second blade 312 are perpendicular to each other, and the first set of blades 107 and the second set of blades 302 are also arranged perpendicularly, the first set of blades 107 and the second set of blades 302 can guide the airflow through the air outlet 100 from two different dimensions. When the air outlet 100 is installed inside a vehicle, the first set of blades 107 and the second set of blades 302 can cooperate to adjust the airflow direction of the air outlet 100 in four different directions: up, down, left, and right.

[0040] like Figure 3As shown, the transmission assembly 303 is connected to the first set of blades 107 and the second set of blades 302, thereby being able to drive the first set of blades 107 and the second set of blades 302 to their respective appropriate positions. The drive device 103 is used to drive the first set of blades 107, and the additional drive device 104 is used to drive the second set of blades 302. The drive device 103 includes a gear transmission portion 315, which is connected to the transmission assembly 303. The drive device 103 can drive the transmission assembly 303 through electric drive to drive the first set of blades 107 to the appropriate position. The additional drive device 104 is directly connected to the second set of blades 302, and can be driven by the electric drive of the additional drive device 104 to move the second set of blades 302 to the appropriate position. For the air outlet 100 in manual air adjustment mode, the user can directly adjust the position of the first set of blades 107 and the second set of blades 302 by manually operating the manual operation unit 109 in the transmission assembly 303. For the air outlet 100 in electric air adjustment mode, the user can directly adjust the position of the first set of blades 107 and the second set of blades 302 by electrically driving the drive device 103 and the additional drive device 104. The air outlet 100 in electric air adjustment mode uses two motors, the drive device 103 and the additional drive device 104, to drive the first set of blades 107 and the second set of blades 302 respectively. Therefore, the first set of blades 107 and the second set of blades 302 can operate automatically and independently of each other. This arrangement enables the air outlet 100 to operate continuously in the automatic air sweeping mode, meeting the user's demand for the automatic air sweeping mode of the automobile air conditioner.

[0041] Figure 4 for Figure 3 A perspective view of the middle transmission assembly 303, Figure 5 for Figure 4 Exploded view of the transmission assembly 303. Figure 4 and Figure 5 As shown, the transmission assembly 303 includes a lever device 401, a slider 403, a first transmission member 405, a second transmission member 407 and a first limit member 110. Along the direction in which the transmission assembly 303 extends, the transmission assembly 303 includes three sections, namely the handle section 411, the first blade transmission section 412 and the second blade transmission section 413. Among them, the slider 403 is located in the handle section 411, the first transmission member 405 and the first limit member 110 are located in the first blade transmission section 412, the second transmission member 407 is located in the second blade transmission section 413, and the lever device 401 extends in the handle section 411, the first blade transmission section 412 and the second blade transmission section 413. Figure 3It can be seen that the first blade transmission section 412 is connected to the first group of blades 107, and is used to directly drive the first group of blades 107 to move to a suitable position, and the second blade transmission section 413 is connected to the second group of blades 302, and is used to directly drive the second group of blades 302 to move to a suitable position.

[0042] The lever device 401 is in the shape of a long strip, combined with Figure 3 As can be seen, the lever assembly 401 extends generally along the length of the housing 101. Along its length, the lever assembly 401 comprises three sections: a handle section 511, a first blade transmission section 512, and a second blade transmission section 513. The structure of the lever assembly 401 forms the basic architecture of the transmission assembly 303, with the three sections of the lever assembly 401 corresponding to the three sections of the transmission assembly 303. The handle section 511 forms the basic architecture of the handle section 411, the first blade transmission section 512 forms the basic architecture of the first blade transmission section 412, and the second blade transmission section 513 forms the basic architecture of the second blade transmission section 413.

[0043] The handle 511 includes a manual operating portion 109, a coupling platform 510, and a second coupling portion 502. The coupling platform 510 is generally flat, with the manual operating portion 109 disposed on its upper surface and the second coupling portion 502 disposed on its lower surface. The second coupling portion 502 is a long, rectangular protrusion extending along the length of the lever assembly 401 and configured to engage the slider 403. The second coupling portion 502 extends along the entire length of the coupling platform 510 and has an isosceles trapezoidal cross-section. The top surface of the second coupling portion 502 is connected to the lower surface of the coupling platform 510, corresponding to the upper base of the isosceles trapezoidal cross-section. The bottom surface of the second coupling portion 502 is parallel to the lower surface of the coupling platform 510, corresponding to the lower base of the isosceles trapezoidal cross-section. The width of the top surface of the second coupling portion 502 is smaller than the width of the bottom surface, resulting in the two side surfaces of the second coupling portion 502 extending obliquely downward from the lower surface of the coupling platform 510.

[0044] The first blade transmission section 512 includes a groove portion 514 and a drive joint portion 457. The groove portion 514 is connected to the joint platform 510 and extends outward from one end of the joint platform 510. The groove portion 514 includes two parallel slats 515, and the two slats 515 are the same in size and shape and are spaced apart on the same plane. The upper surface formed by the two slats 515 is slightly lower than the upper surface of the joint platform 510, and the lower surface formed by the two slats 515 is slightly lower than the lower surface of the joint platform 510. The interval between the two slats 515 forms a groove 516, and the groove 516 extends along the length direction of the lever device 401. The drive joint portion 457 is plate-shaped, arranged at the end of the extension direction of the groove portion 514, and extends vertically downward from the end of the groove portion 514. Combination Figure 3 It can be seen that the drive engaging portion 457 extends in a plane perpendicular to the length direction of the housing 101, and the flat plate formed by the extension of the drive engaging portion 457 is roughly isosceles trapezoidal. The top of the drive engaging portion 457 is connected to the groove portion 514, forming the upper base of the isosceles trapezoid. The two side portions of the drive engaging portion 457 extend obliquely downward. The drive engaging portion 457 is provided with a meshing tooth portion 415 at the lower base of the isosceles trapezoid. The meshing tooth portion 415 includes a plurality of meshing teeth, which extend along the width direction of the housing 101 and are used to mesh with the gear transmission portion 315 of the drive device 103.

[0045] The second blade transmission section 513 includes a transmission rod 423 and two transmission couplings 509. The transmission rod 423 is connected to the drive coupling 457 and is combined with the transmission rod 423 to drive the second blade transmission section 513. Figures 3 to 5 As can be seen, the transmission rod 423 extends generally along the length of the housing 101. The transmission rod 423 includes a transition section 533 and a horizontal section 523. The transition section 533 is located at the connection with the drive coupling 457. The transition section 533 has a circular bend, providing a smooth transition between the drive coupling 457 and the horizontal section 523. The horizontal section 523 is horizontally disposed and extends along the length of the housing 101. The transmission coupling 509 is disposed on the lower surface of the horizontal section 523, with two transmission couplings 509 located at either end of the length of the horizontal section 523. Each transmission coupling 509 is provided with a coupling hole 519. Both coupling holes 519 have a circular cross-section, and their axial directions align with the length of the horizontal section 523. The distance between the two transmission couplings 509 is approximately the same as the length of the second transmission member 407. This arrangement enables the second blade transmission section 513 to connect to the second transmission member 407.

[0046] The slider 403 is roughly rectangular and includes a second guide portion 503, a first engagement portion 504, and a housing connection portion 525. The second guide portion 503 is located on the top surface of the slider 403 and is configured to engage with the second engagement portion 502 on the bottom surface of the engagement platform 510. Corresponding to the second engagement portion 502, which is a long, raised strip, the second guide portion 503 is a long, recessed groove, and the groove cross-section is the same as the raised cross-section, both being an isosceles trapezoid. The second guide portion 503 extends along a second movement direction. When the second engagement portion 502 of the lever assembly 401 is engaged and mounted to the second guide portion 503 of the slider 403, the slider 403 can guide the lever assembly 401 to move along the second movement direction. In this embodiment, the second movement direction is the longitudinal direction of the housing 101. In other words, the lever assembly 401 can slide along the longitudinal direction of the housing 101 under the guidance of the slider 403. The isosceles trapezoidal cross-section helps ensure the connection and fit between the second engaging portion 502 and the second guiding portion 503, preventing the lever assembly 401 from slipping out of the upper portion of the slider 403 during its sliding motion relative to the slider 403. The first engaging portion 504 is located on the bottom surface of the slider 403. The first engaging portion 504 extends in the same direction as the first guiding portion 201, both extending along the first direction of movement. In this embodiment, the first engaging portion 504 and the first guiding portion 201 both extend along the width of the housing 101. The housing connecting portion 525 is located on the side of the slider 403 and is used for connection to the housing 101. The housing connecting portion 525 is elongated and extends on the slider 403 in the same direction as the first engaging portion 504.

[0047] The first transmission member 405 includes an intermediate plate 526, a protrusion 508, and a connecting portion 507. The intermediate plate 526 is an elongated plate, including a front side 529 and a rear side 528. The protrusion 508 and connecting portion 507 are disposed below the intermediate plate 526, at either end of the intermediate plate 506 along its length. The protrusion 508 extends downward from the lower end of the intermediate plate 526 and is coplanar with the intermediate plate 526. The provision of the protrusion 508 facilitates installation of the first transmission member 405 on the lever device 401. One end of the connecting portion 507 is connected to the lower end of the intermediate plate 526 and extends toward the front side 529 of the intermediate plate 526. The connecting portion 507 is generally parallel to the intermediate plate 526, but not coplanar with it. The connecting portion 507 extends vertically downward from the front side 529. A connecting hole 506 is provided in the connecting portion 507 . The connecting hole 506 is substantially in an oblong shape and is used to connect with one of the blades in the first set of blades 107 to drive the first set of blades 107 to move to a suitable position.

[0048] The second transmission member 407 includes a pivot shaft 517 and a fork member 518. The pivot shaft 517 is rod-shaped, and the length of the pivot shaft 517 matches the distance between the two transmission couplings 509 on the lever device 401. The shapes and sizes of the two ends of the pivot shaft 517 in the length direction respectively match the two engagement holes 519 in the two transmission couplings 509. The setting of the pivot shaft 517 can facilitate the second transmission member 407 to be pivotally connected to the lever device 401. The fork member 518 includes a connecting end 520 and a fork end 521. The connecting end 520 is connected to the outer surface of the pivot shaft 517 and extends along the length direction of the pivot shaft 517. The fork end 521 is located below the connecting end 520. The fork member 518 gradually narrows in the process of extending from the connecting end 520 to the fork end 521 to facilitate the connection with the second set of blades 302. The fork member 518 is provided with a slot 417, which extends from the fork end 521 toward the connecting end 520, thereby forming two oppositely disposed fork rods 522. The slot 417 in the fork member 518 is used to connect with a blade in the second set of blades 302 to drive the second set of blades 302 to move to a suitable position.

[0049] like Figure 5 As shown, the bottom surface of the first position-limiting member 110 is provided with a slot 501, which extends along the length of the first position-limiting member 110. The width of the slot 501 is the same as the thickness of the intermediate plate 526 at the top of the first transmission member 405, and the length of the slot 501 is greater than the length of the intermediate plate 526, so that the top of the first transmission member 405 can be inserted into the slot 501 of the first position-limiting member 110. The first position-limiting member 110 is provided with a plug-in portion 524 at each end along its length. The two plug-in portions 524 can mate with the two slots 116 on the housing 101 to mount the first position-limiting member 110 to the housing 101.

[0050] Figure 6 for Figure 4 The perspective view of the middle transmission assembly 303 after removing the first limiting member 110 shows the installation structure of the slider 403 and the first transmission member 405 on the lever device 401. Figure 5 and Figure 6 As can be seen, when the second engaging portion 502 of the lever assembly 401 is inserted into the second guide portion 503 of the slider 403, the upper surface of the slider 403 abuts against the lower surface of the engaging platform 510. Because the lower surface formed by the two strips 515 of the groove 514 of the lever assembly 401 is slightly lower than the lower surface of the engaging platform 510, after the slider 403 is mounted on the lever assembly 401, the lower surface of the slider 403 body is substantially flush with the lower surface formed by the two strips 515 of the lever assembly 401. This arrangement allows the lever assembly 401, with the slider 403 attached, to be stably mounted on the housing boss 115 of the housing 101.

[0051] The first transmission member 405 is installed on the lever device 401 perpendicular to the length direction of the lever device 401. Figure 2 、 Figure 3 and Figure 6 As can be seen, the lever assembly 401 extends along the length of the housing 101, while the middle plate 526 of the first transmission member 405 extends along the width of the housing 101. The first transmission member 405 is mounted on two slats 515 in the groove 514 of the lever assembly 401. The middle plate 526 of the first transmission member 405 is located above the two slats 515, with the protrusion 508 inserted into the groove 516. The connecting portion 507 is located on one side of the lever assembly 401 in the width direction. The width of the protrusion 508 of the first transmission member 405 is the same as the width of the groove 516 between the two slats 515, thereby fixing the first transmission member 405 relative to the lever assembly 401 in the width direction of the housing 101. The protrusion 508 of the first transmission member 405 can slide along the length of the groove 516, allowing the first transmission member 405 to move relative to the lever assembly 401 in the length direction of the housing 101.

[0052] Figure 7 for Figure 1 The longitudinal cross-sectional view of the air outlet 100 at the position of the first limiting member 110 shows the matching relationship between the first transmission member 405 and the first limiting member 110. Figure 4 and Figure 7 As can be seen, the first stopper 110 is disposed above the first transmission member 405. The height of the slot 501 in the first stopper 110 is the same as the height of the intermediate plate 526 in the first transmission member 405, so that the intermediate plate 526 is completely accommodated in the slot 501. Because the length of the slot 501 is greater than the length of the intermediate plate 526, the intermediate plate 526 of the first transmission member 405 can move in the longitudinal direction of the slot 501. In addition, because the first stopper 110 presses on the upper portion of the first transmission member 405, the first stopper 110 prevents the first transmission member 405 from slipping out of the lever device 401 during its movement along the longitudinal direction of the first stopper 110.

[0053] Combine Figures 1 to 7As can be seen, when the transmission assembly 303 is installed in the housing 101, the first engaging portion 504 at the bottom of the slider 403 is inserted into the first guide portion 201 of the housing 101, and the housing connecting portion 525 on the side of the slider 403 is inserted into the connecting groove (not shown) provided in the housing boss 115 along the width direction of the housing 101. The first guide portion 201 can guide the slider 403 to slide along the width direction of the housing 101. Because the lever assembly 401 and the slider 403 are connected by the second engaging portion 502 and the second guide portion 503 extending along the length of the housing 101, the lever assembly 401 also moves along the width direction of the housing 101 (i.e., the first movement direction) as the slider 403 slides along the width direction of the housing 101. In addition, because the second guide portion 503 in the slider 403 guides the second engaging portion 502 in the lever assembly 401, the lever assembly 401 can also move along the length direction of the housing (i.e., the second movement direction). In other words, the lever device 401 can move in both the length and width directions of the housing 101. Since the manual operation portion 109 is provided on the lever device 401 and is accessible to the user, the user can control the movement of the lever device 401 in both the length and width directions of the housing by operating the manual operation portion 109.

[0054] Figure 8 Shown Figure 3 The driving structure of the first set of blades 107 is shown in FIG. 1 for convenience of illustration. Figure 8 The driving device 103 is omitted. Figure 7 and Figure 8 It can be seen that the first transmission member 405 is connected to the outermost first blade 117 in the first set of blades 107. The outermost first blade 117 has a protrusion 702 at its bottom near the manual operation portion 109. The protrusion 702 protrudes outward from the end of the first blade 117. The protrusion 702 of the first blade 117 is inserted into the connecting hole 506 of the first transmission member 405. Since the connecting hole 506 is oblong and the cross-section of the protrusion 702 is roughly circular, the protrusion 702 can move within the range limited by the connecting hole 506. Figure 7 and 8As shown, in the initial state, the first transmission member 405 is located at the leftmost end of the slot 501 in the first stopper 110. When the user operates the manual operating portion 109 to slide the lever assembly 401 rightward along the width of the housing 101, the first transmission member 405 mounted on the lever assembly 401 also moves rightward with the lever assembly 401. Because the protrusion 702 of the outermost first blade 117 is disposed within the connecting hole 506 of the first transmission member 405, as the connecting hole 506 moves rightward, the protrusion 702 gradually moves upward, thereby driving the outermost first blade 117 to rotate counterclockwise about its corresponding first rotation axis 307. Because the three first blades 117 in the first set of blades 107 are interlocked, as the outermost first blade 117 rotates counterclockwise, the other two blades also rotate counterclockwise from their vertically extending direction to an offset direction. When the lever 401 is moved to the rightmost position within the housing boss 115, the first set of blades 107 rotates to the maximum offset position. If the first set of blades 107 needs to be restored from the larger offset position to the smaller offset position or to the vertical extension direction, the manual operating portion 109 can be moved leftward to drive the first set of blades 107 to rotate clockwise via the transmission assembly 303.

[0055] like Figure 7 and 8 As shown, because the drive engagement portion 457 provided on the shift lever assembly 401 can mesh with the gear transmission portion 315 of the drive assembly 103, the movement of the first set of blades 117 can also be electrically driven by the drive assembly 103. When the gear transmission portion 315 of the drive assembly 103 rotates clockwise using electricity, the meshing relationship between the gear transmission portion 315 and the drive engagement portion 457 can drive the shift lever assembly 401 from left to right. As the shift lever assembly 401 moves from left to right, the first transmission member 405 also moves rightward, thereby driving the first set of blades 107 to rotate counterclockwise about the first rotation axis 307, thereby changing the deflected position of the first set of blades 107. Similarly, when the gear transmission portion 315 of the drive assembly 103 rotates counterclockwise using electricity, the meshing relationship between the gear transmission portion 315 and the drive engagement portion 457 can drive the shift lever assembly 401 from right to left. As the lever device 401 moves from right to left, the first transmission member 405 also moves leftward, thereby driving the first set of blades 107 to rotate clockwise around the first rotation axis 307, so that the first set of blades 107 returns from a larger offset position to a smaller offset position or a vertical extension direction.

[0056] Figure 9 Shown Figure 3 The driving structure of the second set of blades 302 is shown in FIG. 1 for convenience of illustration. Figure 9The additional drive device 104 is omitted. A second blade 312 in the second set of blades 302 is provided with two baffles 902 and a connecting rod 901. In this embodiment, the second blade 312 is the second blade 312 closest to the manual operation portion 109. In other embodiments, the second blade 312 provided with two baffles 902 and a connecting rod 901 may also be another second blade 312 in the second set of blades 302. Figure 9 As shown, two baffles 902 extend vertically upward from the upper surfaces of the corresponding second blades 312. A connecting rod 901 is connected between the two baffles 902 and extends along the first movement direction (i.e., the width direction of the housing 101). A second transmission device 407 connected below the lever assembly 401 is connected to the second blade 312, on which the connecting rod 901 is located. The connecting rod 901 is inserted into a slot 417 of the second transmission device 407. When a user activates the manual operating portion 109, causing the lever assembly 401 to move leftward relative to the slider 403 along the length of the housing 101 (i.e., the second movement direction), the second transmission device 407 connected to the outer side of the connecting rod 901 drives the connecting rod 901 upward along the slot 417, thereby causing the second blade 312, on which the connecting rod 901 is located, to rotate counterclockwise about its own second rotation axis 317. Because the second set of blades 302 are interlocked, the other blades in the second set of blades 302 can also rotate counterclockwise about their respective second rotation axes 317 driven by the transmission assembly 303. During this process, the second set of blades 302 can rotate from a substantially horizontal position to a position offset from the horizontal. Similarly, if the second set of blades 302 needs to be rotated from an offset position to a horizontal position, the manual operating unit 109 can be moved to move the lever 401 rightward relative to the slider 403 along the length of the housing 101 (i.e., the second movement direction), thereby driving the second set of blades 302 to rotate clockwise via the transmission assembly 303. To prevent interference between the second transmission assembly 407 and the second set of blades 302 during movement, the second blade 312 provided with the connecting rod 901 is hollowed out at the blade position below the connecting rod 901. Furthermore, a portion of the second blade 312 adjacent to the second blade 312 provided with the connecting rod 901 has a portion of the second blade 312, which is likely to interfere, protruding toward the side away from the second transmission assembly 407. The above arrangement neither hinders the driving effect of the second transmission device 407 on the second set of blades 302 , nor affects the guiding effect of the second set of blades 302 on the airflow inside the air outlet 100 .

[0057] like Figure 9As described above, the second blade 312 provided with the connecting rod 901 is provided with a drive connection portion 903 at one end in the width direction of the housing 101. The drive connection portion 903 is used to connect to the additional drive device 104 so as to drive the second set of blades 302 to a suitable deflection position through the electric drive of the additional drive device 104. In other embodiments, the additional drive device 104 may not be connected to the second blade 312 provided with the connecting rod 901, but may be connected to other blades in the second set of blades 302, and can also drive all the second blades 312 to move in conjunction. It should be understood that when the additional drive device 104 is used to directly drive the second set of blades 302 to rotate, the transmission assembly 303 will also generate associated motion due to the connection relationship between the transmission assembly 303 and the second set of blades 302, but the above-mentioned associated motion will not interfere with the electric drive of the additional drive device 104.

[0058] Combine Figures 1 to 9 As can be seen, when the lever assembly 401 moves along the width of the housing 101 (i.e., the first movement direction), the first transmission member 405 can drive the first set of blades 107 to rotate about the axis to a suitable position. Because the second transmission member 407 is connected to the lever assembly 401, within a certain range, the second transmission member 407 will also move along the width of the housing 101 with the lever assembly 401. It is worth noting that because the connecting rod 901 provided on the second blade 312 extends along the width of the housing, the movement of the second transmission member 407 along the width of the housing 101 follows the direction of the connecting rod 901 and does not cause the corresponding second blade 312 to rotate. In other words, the movement of the lever assembly 401 along the width of the housing 101 can only drive the movement of the first set of blades 107, but cannot drive the movement of the second set of blades 302. In addition, since the second transmission member 407 is pivotally connected to the lever device 401 via the engagement hole 519 and the pivot shaft 517, when the lever device 401 moves along the width direction of the housing 101, the offset distance of the second transmission member 407 in the width direction of the housing 101 is smaller than the offset distance of the lever device 401 in the width direction of the housing 101. In other words, even if the connecting rod 901 provided on the second blade 312 is only relatively short, it can generally meet the requirements for the second transmission member 407 to move along the length direction of the connecting rod 901. In addition, as Figure 9 As shown, the two baffles 902 provided at both ends of the connecting rod 901 can also ensure the connection between the second transmission member 407 and the second set of blades 302 to prevent the second transmission member 407 from slipping off from the second set of blades 302 during movement.

[0059] When the lever device 401 moves along the length direction of the housing 101 (i.e., the second movement direction), the second transmission member 407 can drive the second set of blades 302 to rotate around the axis to a suitable position. It is worth noting that although the first transmission member 405 is connected to the lever device 401, the first transmission member 405 will not move along the length direction of the housing 101 with the lever device 401. In other words, the movement of the lever device 401 along the length direction of the housing 101 can only drive the second set of blades 302 to move, but cannot drive the first set of blades 107 to move. Figure 1 、 Figure 4 and Figure 6 As shown, because the intermediate plate 526 of the first transmission member 405 is disposed within the first stopper 110, the first transmission member 405 can remain relatively stationary with the first stopper 110 in the longitudinal direction of the housing 101. However, because the first stopper 110 is fixed to the housing 101, the first transmission member 405 can only move in the width direction of the housing 101 and cannot move in the longitudinal direction of the housing 101. When the lever assembly 401 moves along the longitudinal direction of the housing 101, the first transmission member 405 slides along the slot 516 of the lever assembly 401 in the longitudinal direction of the housing 101 and is not driven by the lever assembly 401. Therefore, the second set of blades 302 is not affected by the movement of the lever assembly 401 along the longitudinal direction of the housing 101.

[0060] In other words, the lever device 401 can drive the first set of blades 107 and the second set of blades 302 separately, and the movements of the first set of blades 107 and the second set of blades 302 are independent of each other. The user only needs to control the movement of the manual operating portion 109 on the lever device 401 in the first movement direction and the second movement direction to independently control the positions of the first set of blades 107 and the second set of blades 302. Therefore, the operation of the air outlet 100 in the manual air adjustment mode is simple and easy to operate, and is user-friendly.

[0061] In this embodiment, the first transmission member 405 and the second transmission member 407 are configured to drive the first set of blades 107 and the second set of blades 302 to appropriate positions by respectively driving one blade in the first set of blades 107 and one blade in the second set of blades 302. In other embodiments, the first transmission member 405 and the second transmission member 407 can also be configured to respectively drive multiple blades in the first set of blades 107 and multiple blades in the second set of blades 302, such as two or three blades.

[0062] The structure of the air outlet 100 of the present application can meet the configuration requirements of both the manual wind direction adjustment mode and the electric wind direction adjustment mode. Figures 1 to 9As shown, if all the components of the air outlet 100 are fully installed, the electric adjustment of the wind direction of the air outlet 100 can be achieved through the electric drive of the driving device 103 and the additional driving device 104. For the air outlet 100 in the electric air adjustment mode, the driving device 103 and the additional driving device 104 have a braking effect on the first group of blades 107 and the second group of blades 302. At this time, if the user manually moves the manual operating part 109 of the lever device 401, it will not drive the first group of blades 107 and the second group of blades 302 to move. In some embodiments, in order to avoid user misoperation and increase the aesthetics, a top cover can be provided above the shell boss 115 that accommodates the manual operating part 109, and the manual operating part 109 can be hidden inside the shell 101 by the provision of the top cover. When preparing the air outlet 100 in the manual air adjustment mode, the air outlet 100 does not need to be equipped with the driving device 103 and the additional driving device 104. That is to say, in Figures 1 to 9 The electric air-adjustment mode air outlet 100 shown above can be replaced by removing the drive device 103 and the additional drive device 104 to obtain a manual air-adjustment mode air outlet 100. The user manually controls the manual operating portion 109 to move in both the length and width directions of the housing 101 to adjust the wind direction of the air outlet 100. Since the structures and components of the manual air-adjustment mode and electric air-adjustment mode air outlets 100 are almost identical, when a car adopts the air outlet 100 of this application, the manufacturer only needs to develop one set of air outlet molds to meet the configuration requirements of both air outlets 100. In addition, the car manufacturer can use the same car panel to accommodate the installation of both air outlets 100, greatly reducing the production cost and production efficiency of the car.

[0063] Although the present application is described with reference to the specific embodiments shown in the drawings, it should be understood that the pressure balancing device 101 of the present application may be structured in many different ways without departing from the spirit, scope, and context of the present application. Those skilled in the art will also recognize that there are many ways to modify the structural details of the embodiments disclosed in the present application, all of which fall within the spirit and scope of the present application and the claims.
