Description

Technical Field

[0001] The invention relates to the technical field of automobile air conditioners, and in particular to a damper adjustment component and a vehicle. Background Art

[0002] The air outlet assembly of the automobile air conditioner is arranged in the cockpit of the car and is a functional component that is frequently operated by the passengers in the cockpit. When designing the air outlet structure, it is not only required to be flexible and convenient in operation and meet the requirements of air outlet performance, but also to consider the different requirements of different users for air volume, air outlet softness, etc.

[0003] In the existing damper adjustment assembly with a soft wind plate, the connecting rod mechanism that drives the soft wind plate to close has a complex structure, with many components, and the movement of the components is not smooth, which is prone to vibration and abnormal noise. The arrangement of the connecting rod mechanism requires a large space. Although it can achieve a soft wind effect, it cannot close the air outlet where the damper is provided, and can only switch between the soft wind position and the normal air outlet position.

[0004] In addition, there is also a damper adjustment assembly, including a bevel gear and two semicircular dampers. A semi-bevel gear portion is provided on the two dampers, and the two semi-bevel gear portions are engaged with the bevel gear. The dampers are driven to open or close by turning a knob. However, the rotating axis of this damper is parallel to the straight edge of the damper. By turning the knob, only the size of the damper opening can be changed, and the air outlet direction cannot be adjusted, and the effect of soft wind cannot be achieved, which will cause people to feel dry when the air conditioner is heating, and feel that parts of the air are too cold when cooling, and other bad experiences. Summary of the invention

[0005] The first object of the present invention is to provide a damper adjustment component with a simple structure, smooth movement of each component, no abnormal noise, and the ability to switch between normal air outlet state, closed state and soft wind state to improve user experience.

[0006] A second object of the present invention is to provide a vehicle having the above-mentioned throttle adjustment assembly.

[0007] To achieve the above-mentioned first purpose, the present invention provides a damper adjustment assembly, including a damper assembly and a driving member; an air outlet channel is provided in an air outlet body, and the damper assembly is arranged in the air outlet channel and is hinged to the air outlet body; the damper assembly includes a damper and a wind shield, and ventilation holes are provided along the thickness direction of the damper, and the wind shield is hinged to the damper; the driving member can drive the damper assembly to rotate between a normal air outlet position, a closed position and a soft wind position; in the normal air outlet position, the damper is parallel to or at an acute angle to the air outlet direction of the air outlet channel; in the closed position, the damper is perpendicular to the air outlet direction, the wind shield is located on the upstream side of the damper, and the wind shield is in contact with the damper and covers the ventilation holes on the damper; in the soft wind position, the damper is perpendicular to the air outlet direction, the wind shield is located on the downstream side of the damper, and the wind shield is at an angle to the damper and opens the ventilation holes on the damper.

[0008] It can be seen from the above scheme that by opening a ventilation hole on the damper and providing a wind shield connected to the damper, when the damper is rotated to different positions, the wind shield is automatically opened and closed by the action of the airflow. When a normal air outlet effect is required, the driving part drives the damper assembly to rotate so that the damper is parallel to or at an angle to the air outlet direction of the air outlet channel, thereby opening the air outlet channel, and at the same time the damper can guide the airflow in the air outlet channel, so that the air outlet direction can be adjusted by adjusting the rotation angle of the damper; when a soft wind effect is required, the driving part drives the damper assembly to rotate so that the damper is perpendicular to the air outlet direction. At this time, the wind shield is located on the downstream side of the damper. Under the push of the air flow pressure, the wind shield separates from the damper and opens the damper. The airflow is blown out from the small-sized ventilation holes to form a soft wind, so that the exhausted wind is transported out more evenly, which greatly weakens the blowing intensity blown out from the air outlet, has a windless effect, and improves the user's comfort; when there is no need to discharge air, the driving member drives the damper assembly to rotate, so that the damper is perpendicular to the wind outlet direction. At this time, the wind shield is located on the upstream side of the damper. Under the driving effect of the air pressure of the air flow, the wind shield adheres to the damper and covers the ventilation holes on the damper, and the air flow cannot be sent out, thereby realizing the closure of the air outlet channel. The damper adjustment assembly of the present invention has a simple structure, and each component moves smoothly without generating abnormal noise. At the same time, it can realize switching between normal air outlet state, closed state and soft wind state, thereby improving user experience.

[0009] A preferred solution is that the number of the damper assemblies is two, and the arrangement direction of the two damper assemblies is parallel to the rotation axis of the damper and perpendicular to the air outlet direction of the air outlet channel.

[0010] It can be seen that more stable movement of each component can be achieved through the joint action of two dampers arranged along the rotation axis.

[0011] A preferred solution is that an angle limiter is further provided on the damper, and the angle limiter cooperates with the wind shield to limit the swing angle of the wind shield relative to the damper.

[0012] It can be seen that the angle limiter is used to limit the swing angle of the damper to prevent the damper from swinging excessively and being unable to reset.

[0013] A preferred solution is that the driving member includes a coaxially arranged knob, a driving rod and an active bevel gear, the knob and the active bevel gear are respectively arranged at both ends of the driving rod, and the axis of the driving member is parallel to the air outlet direction; the damper is provided with a driven bevel gear, the axis of the driven bevel gear is parallel to the rotation axis of the damper, the damper assembly is arranged at the air inlet end of the air outlet channel, and the knob is located at the air outlet end of the air outlet channel; when the knob is rotated under force, the active bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the damper to rotate.

[0014] It can be seen that the user can drive the active bevel gear to rotate by turning the knob, and the active bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the corresponding damper to rotate around the rotating shaft extending parallel to the arrangement direction of the damper, and the damper can rotate around the rotating shaft within a range of 360 degrees. The structure of the driving part is simple, which simplifies the opening and closing method of the damper, and each component moves smoothly without generating abnormal noise.

[0015] A further solution is that, in a direction parallel to the rotation axis of the damper, a side of the wind deflector away from the driven bevel gear is hinged to the damper.

[0016] It can be seen that when the side of the wind deflector away from the driven bevel gear is hinged to the damper, it can ensure that the wind deflector can swing stably.

[0017] A preferred solution is that the damper adjustment assembly also includes a support and a direction adjustment bracket, the support includes a cylindrical mounting portion, and the air outlet body is installed in the mounting portion; the direction adjustment bracket is annular, and in the radial direction of the air outlet body, the direction adjustment bracket is located between the support and the air outlet body, and the driving member, the direction adjustment bracket, the mounting portion and the air outlet body are coaxially arranged; the direction adjustment bracket and the support are hinged by a first hinge shaft, and the air outlet body and the direction adjustment bracket are hinged by a second hinge shaft, and the axis of the first hinge shaft intersects with the axis of the second hinge shaft and are both perpendicular to the axis of the direction adjustment bracket.

[0018] It can be seen that the mounting portion is connected to the support via the direction adjustment bracket, so that the air outlet angle can be adjusted within a wide range, and the structure is simple and has high adjustment flexibility.

[0019] A further solution is that the first hinge shaft includes a first hinge part and a second hinge part arranged coaxially, the first hinge part and the second hinge part are arranged radially along the direction adjustment bracket and both are rotatably coordinated with the support; the second hinge shaft includes a third hinge part and a fourth hinge part arranged coaxially, the third hinge part and the fourth hinge part are arranged radially along the direction adjustment bracket and both are rotatably coordinated with the air outlet body.

[0020] It can be seen that the setting of the first hinge shaft can realize the rotation of the direction adjustment bracket relative to the support, and the setting of the second hinge shaft can realize the rotation of the direction adjustment bracket relative to the air outlet body. The two hinge shafts intersect, so that the air outlet body can adjust the air outlet direction within a larger range relative to the support.

[0021] A further solution is that at least one of the first hinge part and the second hinge part protrudes from the outer peripheral wall of the direction adjustment bracket in a direction away from the central axis of the direction adjustment bracket; and / or at least one of the third hinge part and the fourth hinge part protrudes from the inner peripheral wall of the direction adjustment bracket toward the central axis of the direction adjustment bracket.

[0022] It can be seen from this that the first hinge part and the second hinge part can be protrusions protruding outward from the outer peripheral wall of the direction adjustment bracket, or can be grooves arranged on the peripheral wall of the direction adjustment bracket, and the third hinge part and the fourth hinge part can be protrusions protruding inward from the inner peripheral wall of the direction adjustment bracket, or can be grooves arranged on the peripheral wall of the direction adjustment bracket.

[0023] A further solution is that a first protrusion is provided on the outer circumferential wall of the direction adjustment bracket, and the first protrusion is located between the first hinge part and the second hinge part in the circumferential direction of the direction adjustment bracket; and / or a second protrusion is provided on the inner circumferential wall of the direction adjustment bracket, and the second protrusion is located between the third hinge part and the fourth hinge part in the circumferential direction of the direction adjustment bracket.

[0024] It can be seen that the first protrusion can increase the friction between the direction adjustment bracket and the support, so that after the air outlet direction is adjusted, the position of the direction adjustment bracket is positioned. The second protrusion can increase the friction between the direction adjustment bracket and the air outlet body, so that after the air outlet direction is adjusted, the position of the air outlet body relative to the direction adjustment bracket is positioned. Thereby, the air outlet body can be rotated arbitrarily within a certain angle, and under the action of each protrusion, the air outlet body can be fixed at a certain angle.

[0025] A further solution is that two groups of first protrusions are provided on the outer peripheral wall of the direction adjustment bracket, and the two groups of first protrusions are arranged opposite to each other along the radial direction of the direction adjustment bracket; and / or two groups of second protrusions are provided on the inner peripheral wall of the direction adjustment bracket, and the two groups of second protrusions are arranged opposite to each other along the radial direction of the direction adjustment bracket.

[0026] It can be seen that the provision of multiple groups of first protrusions and multiple groups of second protrusions can further increase the friction between the direction adjustment bracket and the air outlet body and between the direction adjustment bracket and the support, thereby preventing the inability to adjust the air outlet direction due to the inability to position the air outlet body.

[0027] A further solution is that in each group of first protrusions, the number of first protrusions is more than two, and each first protrusion in the same group is arranged axially along the direction to adjust the bracket; and / or in each group of second protrusions, the number of second protrusions is more than two, and each second protrusion in the same group is arranged axially along the direction to adjust the bracket.

[0028] It can be seen that, since the air outlet body is cylindrical, a plurality of protrusions arranged along the axial direction can further increase the friction between the direction adjustment bracket and the air outlet body and between the direction adjustment bracket and the support, thereby preventing the air outlet body from being unstable in positioning.

[0029] A preferred solution is that along the axial direction of the direction adjustment bracket, the outer diameter of the direction adjustment bracket gradually decreases from the axis of the first hinge shaft to the axial end of the direction adjustment bracket; and / or along the axial direction of the direction adjustment bracket, the inner diameter of the direction adjustment bracket gradually decreases from the axis of the second hinge shaft to the axial end of the direction adjustment bracket.

[0030] This shows that the flexible rotation of the bracket is convenient for direction adjustment.

[0031] A preferred solution is that at least one of the first hinge shaft and the second hinge shaft is located in the middle of the direction adjustment bracket in the axial direction of the direction adjustment bracket. And / or the axis of the first hinge shaft is perpendicular to the axis of the second hinge shaft. And / or the axis of the first hinge shaft and the axis of the second hinge shaft are spaced apart along the axial direction of the direction adjustment bracket.

[0032] To achieve the second objective, the present invention provides a vehicle comprising the above-mentioned air door adjustment assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The vehicle of the present embodiment is a car, and the vehicle includes a damper adjustment assembly, and the damper adjustment assembly is located at the air outlet of the car air conditioner.

[0049] See also Figures 1 to 4 The damper adjustment assembly includes a support 1, a direction adjustment bracket 2, an air outlet body 5, a driving member 3 and two damper assemblies 4. An air outlet channel 51 is provided in the air outlet body 5, and the two damper assemblies 4 are both arranged in the air outlet channel 51 and are both hinged to the air outlet body 5, and the arrangement direction of the two damper assemblies 4 is parallel to the rotation axis of the damper 41 and perpendicular to the air outlet direction of the air outlet channel 51.

[0050] The support 1 includes a cylindrical mounting portion 11, the air outlet body 5 is mounted in the mounting portion 11, the direction adjustment bracket 2 is annular, and in the radial direction of the air outlet body 5, the direction adjustment bracket 2 is located between the support 1 and the air outlet body 5, the driving member 3, the direction adjustment bracket 2, the mounting portion 11 and the air outlet body 5 are coaxially arranged, the direction adjustment bracket 2 and the support 1 are hinged through a first hinge shaft 21, and the air outlet body 5 and the direction adjustment bracket 2 are hinged through a second hinge shaft 22, and the axis of the first hinge shaft 21 and the axis of the second hinge shaft 22 are perpendicularly arranged and both are perpendicular to the axis of the direction adjustment bracket 2. At least one of the first hinge shaft 21 and the second hinge shaft 22 is located in the middle of the direction adjustment bracket 2 in the axial direction of the direction adjustment bracket 2. The axis of the first hinge shaft 21 and the axis of the second hinge shaft 22 are arranged at intervals along the axial direction of the direction adjustment bracket 2, that is, the axis of the first hinge shaft 21 and the axis of the second hinge shaft 22 are not coplanar. The setting of the first hinge shaft 21 can realize the rotation of the direction adjustment bracket 2 relative to the support 1, and the setting of the second hinge shaft 22 can realize the rotation of the direction adjustment bracket 2 relative to the air outlet body 5. The two hinge shafts intersect, so that the air outlet body 5 can adjust the air outlet direction within a larger range relative to the support 1.

[0051] Along the axial direction of the direction adjustment bracket 2, the outer diameter of the direction adjustment bracket 2 gradually decreases from the axis of the first hinge shaft 21 to the axial end of the direction adjustment bracket 2. Along the axial direction of the direction adjustment bracket 2, the inner diameter of the direction adjustment bracket 2 gradually decreases from the axis of the second hinge shaft 22 to the axial end of the direction adjustment bracket 2.

[0052] See also Figures 3 to 5The first hinge shaft 21 includes a first hinge part 211 and a second hinge part 212 arranged coaxially, the first hinge part 211 and the second hinge part 212 are arranged along the radial direction of the direction adjustment bracket 2 and are both rotatably matched with the mounting part 11 of the support 1. The second hinge shaft 22 includes a third hinge part 221 and a fourth hinge part 222 arranged coaxially, the third hinge part 221 and the fourth hinge part 222 are arranged along the radial direction of the direction adjustment bracket 2 and are both rotatably matched with the air outlet body 5.

[0053] The first hinge part 211 and the second hinge part 212 both protrude from the outer peripheral wall of the direction adjustment bracket 2 in a direction away from the central axis of the direction adjustment bracket 2. The third hinge part 221 and the fourth hinge part 222 both protrude from the inner peripheral wall of the direction adjustment bracket 2 toward the central axis of the direction adjustment bracket 2.

[0054] Two groups of first protrusions 23 are arranged on the outer peripheral wall of the direction adjustment bracket 2. In the circumferential direction of the direction adjustment bracket 2, the two groups of first protrusions 23 are located in the middle position between the first hinge part 211 and the second hinge part 212. The two groups of first protrusions 23 are arranged oppositely along the radial direction of the direction adjustment bracket 2. In each group of first protrusions 23, the number of first protrusions 23 is four, and the four first protrusions 23 in the same group are arranged at intervals along the axial direction of the direction adjustment bracket 2. Two groups of second protrusions 24 are arranged oppositely along the radial direction of the direction adjustment bracket 2. In the circumferential direction of the direction adjustment bracket 2, the two groups of second protrusions 24 are located in the middle position between the third hinge part 221 and the fourth hinge part 222. The two groups of second protrusions 24 are arranged oppositely along the radial direction of the direction adjustment bracket 2. In each group of second protrusions 24, the number of second protrusions 24 is four, and the four second protrusions 24 in the same group are arranged at intervals along the axial direction of the direction adjustment bracket 2.

[0055] The first protrusion 23 can increase the friction between the direction adjustment bracket 2 and the support 1, so that after the air outlet direction is adjusted, the position of the direction adjustment bracket 2 is positioned. The second protrusion 24 can increase the friction between the direction adjustment bracket 2 and the air outlet body 5, so that after the air outlet direction is adjusted, the position of the air outlet body 5 relative to the direction adjustment bracket 2 is positioned. Thereby, the air outlet body 5 can be rotated arbitrarily within a certain angle, and under the action of each protrusion, the air outlet body 5 can be fixed at a certain angle.

[0056] See also Figure 2 and Figure 6 Each damper assembly 4 includes a damper 41 and a wind shield 42, both of which are bow-shaped. The damper 41 is hinged to the air outlet body 5 through a damper shaft 411, and the damper shaft 411 is located at the midpoint of the arc-shaped edge 412 of the damper 41, and the damper shaft 411 is perpendicular to the chord edge 413 of the damper 41.

[0057] A plurality of ventilation holes 43 are provided through the damper 41 along the thickness direction. The ventilation holes 43 in this embodiment are in the shape of long strips and are arranged in a matrix on the damper 41. In a direction parallel to the rotation axis of the damper 41, the side of the wind shield 42 away from the driven bevel gear 44 of the damper 41 is hinged to the corresponding damper 41, and the hinge shaft 421 of the wind shield 42 is parallel to the chord side 413 of the damper 41.

[0058] The damper 41 is also provided with an angle limiter (not shown), which cooperates with the wind shield 42 to limit the swing angle of the wind shield 42 relative to the damper 41. Preferably, the angle limiter can be a torsion spring, which is sleeved on the hinge shaft 421 of the wind shield 42. Under the action of the elastic restoring force of the torsion spring, the wind shield 42 is forced to swing toward the corresponding damper 41 and fit with the damper 41. At the same time, the angle limiter can also prevent the wind shield 42 from shaking when the damper assembly 4 is in the normal air outlet position.

[0059] The driving member 3 includes a knob 31, a driving rod 32 and an active bevel gear 33 arranged coaxially. The knob 31 and the active bevel gear 33 are respectively arranged at both ends of the driving rod 32, and the axis of the driving member 3 is parallel to the air outlet direction. The two dampers 41 are each provided with a driven bevel gear 44, and the axis of the driven bevel gear 44 is parallel to the rotation axis of the damper 41. The two damper assemblies 4 are both arranged at the air inlet end of the air outlet channel 51, and the knob 31 is located at the air outlet end of the air outlet channel 51. When the knob 31 is rotated under force, the active bevel gear 33 drives the two driven bevel gears 44 to rotate, and the driven bevel gears 44 drive the corresponding damper 41 to rotate.

[0060] The air inlet end of the air outlet body 5 is provided with a bracket 52, which extends along the radial direction of the air outlet channel 51. The bracket 52 divides the air inlet end of the air outlet channel 51 into a first air inlet 53 and a second air inlet 54 arranged along a first direction. One damper 41 is located at the first air inlet 53 and can cover the first air inlet 53, and the other damper 41 is located at the second air inlet 54 and can cover the second air inlet 54. The bracket 52 is provided with a first installation cavity 521 and a second installation cavity 522. The driven bevel gear 44 on the first damper 41 is located in the first installation cavity 521, and the driven bevel gear 44 on the second damper 41 is located in the second installation cavity 522.

[0061] The user can drive the active bevel gear 33 to rotate by turning the knob 31, and the active bevel gear 33 drives the driven bevel gear 44 to rotate, and the driven bevel gear 44 drives the corresponding damper 41 to rotate around the rotating shaft extending parallel to the arrangement direction of the damper 41, and the damper 41 can rotate around the rotating shaft within a range of 360 degrees. The structure of the driving member 3 is simple, which simplifies the opening and closing method of the damper 41, and each component moves smoothly without generating abnormal noise.

[0062] See also Figure 1 , Figures 7 to 9 The driving member 3 can drive the damper assembly 4 to rotate between the normal air outlet position, the closed position and the soft wind position. Figure 7 As shown, in the normal air outlet position, the air door 41 is parallel to or at an acute angle to the air outlet direction of the air outlet channel 51. Figure 8 As shown, in the closed position, the damper 41 is perpendicular to the air outlet direction, the wind shield 42 is located on the upstream side of the damper 41, and the wind shield 42 is attached to the damper 41 and covers the ventilation hole 43 on the damper 41. Fig. 9 As shown, in the soft wind position, the damper 41 is perpendicular to the wind outlet direction, the wind shield 42 is located on the downstream side of the damper 41, and the side of the wind shield 42 away from the hinge shaft 421 is separated from the damper 41 and the ventilation hole 43 on the damper 41 is opened. At this time, the wind shield 42 forms an acute angle with the damper 41.

[0063] As can be seen from the above, by opening ventilation holes on the damper and providing a wind shield connected to the damper, when the damper is rotated to different positions, the wind shield is automatically opened and closed by the action of the airflow. When a normal air outlet effect is required, the driving part drives the damper assembly to rotate so that the damper is parallel to or at an angle to the air outlet direction of the air outlet channel, thereby opening the air outlet channel, and at the same time the damper can guide the airflow in the air outlet channel, so that the air outlet direction can be adjusted by adjusting the rotation angle of the damper; when a soft wind effect is required, the driving part drives the damper assembly to rotate so that the damper is perpendicular to the air outlet direction. At this time, the wind shield is located on the downstream side of the damper. Under the push of the air flow pressure, the wind shield separates from the damper and opens the damper. The airflow is blown out from the small-sized ventilation holes to form a soft wind, so that the exhausted wind is transported out more evenly, which greatly weakens the blowing intensity blown out from the air outlet, has a windless effect, and improves the user's comfort; when there is no need to discharge air, the driving member drives the damper assembly to rotate, so that the damper is perpendicular to the wind outlet direction. At this time, the wind shield is located on the upstream side of the damper. Under the driving effect of the air pressure of the air flow, the wind shield adheres to the damper and covers the ventilation holes on the damper, and the air flow cannot be sent out, thereby realizing the closure of the air outlet channel. The damper adjustment assembly of the present invention has a simple structure, and each component moves smoothly without generating abnormal noise. At the same time, it can realize switching between normal air outlet state, closed state and soft wind state, thereby improving user experience.

[0064] In addition, the first hinge part and the second hinge part can be protrusions protruding outward from the outer peripheral wall of the direction adjustment bracket, or can be grooves arranged on the peripheral wall of the direction adjustment bracket, and the third hinge part and the fourth hinge part can be protrusions protruding inward from the inner peripheral wall of the direction adjustment bracket, or can be grooves arranged on the peripheral wall of the direction adjustment bracket.
