[0001] The present invention relates to the technical field of air-conditioning air outlets, and specifically to an air outlet adjustment switch. Background Art

[0002] Traditional air-conditioning air outlet adjustment switches usually adopt adjustable grilles and vanes, and use mechanical linkage structures to adjust the wind direction and air volume respectively. The structure is complex and the adjustment is cumbersome. In order to improve the adjustment convenience, the existing air outlet adjustment switches integrate the wind direction and air volume adjustments.

[0003] For example, an air-conditioning air outlet adjustment structure disclosed in a Chinese patent application with the publication number CN 117565637 A includes a housing assembly. A grille assembly for adjusting the air outlet direction is rotatably connected inside the housing assembly. An air door adjustment mechanism is installed inside the housing assembly. One end of the air door adjustment mechanism extends out of the grille assembly and is connected to a wind direction and air volume adjustment member, integrating the adjustment of air volume and wind direction, and the adjustment is convenient.

[0004] However, the air outlet adjustment structure provided by the above solution has a complex structure and a low adjustment accuracy, and cannot accurately adjust the wind direction and air volume of the outlet air.

[0005] Therefore, how to effectively and quickly adjust the wind direction and air volume of the air-conditioning air outlet, and improve the adjustment efficiency and accuracy has become an urgent problem to be solved in this field. Summary of the Invention

[0008] The air volume adjustment module and the wind direction adjustment module are respectively arranged on the first surface and the second surface of the signal trigger module.

[0009] The adjustment button module sequentially passes through the air volume adjustment module, the signal trigger module and the wind direction adjustment module, and is configured such that the rotation of the adjustment button module can drive the air volume adjustment module to rotate synchronously, so that the air volume adjustment module cooperates with the first surface of the signal trigger module to generate an air volume signal.

A gear spring top pin is provided in the housing, and the gear spring top pin is elastically abutted and cooperated with the curved surface adjustment gears.

[0016] Further, the wind direction adjustment module is composed of a slider. A wind direction cavity capable of accommodating the drive shaft therein is formed in the middle of the slider, and trigger fingers are respectively provided at both ends of the top surface of the slider.

[0017] Further, a plurality of contacts for cooperating with the trigger fingers are distributed at both ends of the second surface of the PCBA board. The trigger fingers can generate corresponding wind direction signals by cooperating with the contacts at different positions.

[0018] Further, a base is further included. A chute for cooperating with the slider is provided on the base, and a sliding seat adapted to the chute is provided on the bottom surface of the slider.

[0044] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0045] See Figures 1 to 3 , which shows an example of the air outlet adjustment switch provided by the present invention.

[0046] As can be seen from the figure, the air outlet adjustment switch of this example is used to cooperate with the air conditioner and the blades of the air conditioner, and mainly includes a housing 100, an adjustment button module 200, an air volume adjustment module 300, a signal trigger module 400, a wind direction adjustment module 500 and a control module arranged in the housing 100.

[0047] The air volume adjustment module 300 and the air direction adjustment module 500 are respectively arranged on the first side 401 and the second side 402 of the signal trigger module 400. The adjustment button module 200 sequentially passes through the air volume adjustment module 300, the signal trigger module 400, and the air direction adjustment module 500, and is configured such that the rotation of the adjustment button module 200 can drive the air volume adjustment module 300 to rotate synchronously, so that the air volume adjustment module 300 cooperates with the first side 401 of the signal trigger module 400 to generate an air volume signal. The axial and radial movement of the adjustment button module 200 can drive the air direction adjustment module 500 to move synchronously, so that the air direction adjustment module 500 cooperates with the second side 402 of the signal trigger module 400 to generate an air direction signal, enabling different movement states of the adjustment button module 200 to achieve the adjustment of air volume and air direction, thereby integrating the air volume and air direction adjustment and improving the adjustment efficiency.

[0048] Furthermore, the control module is configured to be able to control the air volume of the air conditioner according to the air volume signal, and can also control the movement state of the blades according to the air direction signal to adjust the air direction, so that the control module can accurately adjust the air volume and air direction of the air conditioner according to the movement amplitude of the adjustment button module 200, thereby improving the adjustment accuracy.

[0049] Among them, the adjustment button module 200 includes a button assembly 210 and a drive shaft 220. The button assembly 210 and the drive shaft 220 can cooperate with each other to transfer the user's adjustment action to the air volume adjustment module 300 and the air direction adjustment module 500, so as to quickly realize the adjustment response of air volume and air direction.

[0050] Specifically, in combination with Figure 2 and Figure 3 , the button assembly 210 includes an upper button 211 and a lower button 212. The upper button 211 is configured with a T-shaped cross-section, with the top extending outside the housing 100 for the user to operate, and the bottom extending into the housing 100 and connecting to the lower button 212. The top of the lower button 212 is provided with a connection hole 213, so that the drive shaft 220 can be connected to the upper button 211 through the connection hole 213, so that when the user operates the upper button 211 to move, it can drive the drive shaft 200 to move synchronously.

[0051] Furthermore, in combination with Figure 1 and Figure 3 , when the upper button 211 drives the drive shaft 200 to move synchronously, the upper button 211 and the drive shaft 20 will move relative to the housing 100, exposing the internal structure of the housing 100. Therefore, the lower button 212 forms an arc-shaped cavity and moves synchronously with the drive shaft 200 to cover and block the internal structure of the housing 100, preventing the entry of dust and impurities, ensuring that the air volume adjustment module 300 and the air direction adjustment module 500 inside the housing 100 are not affected by the external environment, and at the same time improving the aesthetics of this air outlet adjustment switch.

[0052] Combined with Figure 4 , further, an output shaft 221 adapted to the connection hole 213 is formed by extending the top of the drive shaft 220, so that the output shaft 221 passes through the connection hole 213 of the lower button 212 to connect the upper button 211. A spherical movement center 222 is formed in the middle region of the drive shaft 220, so that the movement center 222 can ensure the stable movement of the drive shaft 220 and smoothly transmit the movement to the air volume adjustment module 300 and the air direction adjustment module 500, ensuring that the air volume and air direction can be accurately adjusted.

[0053] Combined with Figures 5 to 7 , correspondingly, the air volume adjustment module 300 is composed of a curved surface block 310. An air volume cavity capable of accommodating the drive shaft 220 is formed in the curved surface block 310, so that the rotation of the upper button 211 can drive the drive shaft 220 to rotate synchronously, thereby driving the curved surface block 310 to rotate synchronously around the drive shaft 220.

[0054] Specifically, combined with Figure 4 , positioning ribs 224 are provided on both sides of the movement center 222 of the drive shaft 220, and positioning grooves 311 for cooperating with the positioning ribs 224 are provided on both sides of the inner wall of the curved surface block 310, so that the positioning ribs 224 can be placed in the positioning grooves 311. As Figure 8 shown, at the same time, the positioning groove 311 is configured as a through hole with a width greater than that of the positioning rib 224, so that there is a gap between the positioning rib 224 and the two side walls of the positioning groove 311, and the gap is adapted to the stroke of the radial movement of the drive shaft 220. When the drive shaft 220 moves axially, the positioning rib 224 can move freely axially in the positioning groove 311. When the drive shaft 220 moves radially, the positioning rib 224 will not generate abutting pressure on the two side walls of the positioning groove 311, so that the axial and radial movements of the drive shaft 220 will not drive the curved surface block 310 to move synchronously, ensuring that the four-way movement of the drive shaft 220 will only be transmitted to the air direction adjustment module 500 to adjust the air direction, and will not be transmitted to the air volume adjustment module 300, ensuring that the air volume is not affected.

[0055] Further, when the drive shaft 220 rotates, the positioning rib 224 rotates synchronously and abuts against the side wall of the positioning groove 311, thereby driving the curved surface block 310 to rotate synchronously and transmitting the movement to the air volume adjustment module 300 to adjust the air volume. At the same time, the curved surface block 310 is configured in a stepped shape, and a plurality of retaining walls 320 are evenly distributed at the bottom, so that when the curved surface block 310 rotates synchronously around the drive shaft 220 and drives the retaining walls 320 to rotate synchronously, the retaining walls 320 can cooperate with the signal trigger module 400 to generate an air volume signal.

[0056] Combined with Figure 7 and Figure 9, correspondingly, the signal trigger module 400 is arranged below the air volume adjustment module 300, such that the air volume adjustment module 300 can move on the first surface 401 of the signal trigger module 400 and cooperate with the first surface 401 of the signal trigger module 400 to generate an air volume signal.

[0057] Specifically, the signal trigger module 400 is composed of a PCBA board 410. A grating 420 is provided on the first surface 401 of the PCBA board 410. The grating 420 is formed with a U-shaped groove adapted to the retaining wall 320 of the curved surface block 310. When the curved surface block 310 rotates around the drive shaft 220 and drives the retaining wall 320 to rotate synchronously, the retaining wall 320 can rotate into the U-shaped groove to block the grating 420 and then rotate out of the U-shaped groove to release the grating 420, so that the grating 420 presents a blocked state or a released state, and whether to switch the air volume size is judged according to the blocked state and the released state.

[0058] As an example, when the retaining wall 320 rotates into the U-shaped groove to block the grating 420 and makes the grating 420 present a blocked state, the grating 420 judges that the air volume size needs to be switched.

[0059] Combined with Figure 10 , further, the grating 420 is provided with a first light outlet 421 and a second light outlet 422 which are distributed in parallel. When the retaining wall 320 rotates into the U-shaped groove from different directions, it will first block the first light outlet 421 or the second light outlet 420, so that the grating 420 can judge the rotation direction of the retaining wall 320 according to the first blocked state of the first light outlet 421 and the second light outlet 420, thereby judging whether to increase or decrease the air volume, so that the PCBA board 410 generates a corresponding air volume signal.

[0060] Combined with Figure 3 , Figure 9 and Figure 10 , as an example, when the retaining wall 320 rotates clockwise into the U-shaped groove and first blocks the first light outlet 421, the grating 420 judges that the air volume needs to be decreased, so that the PCBA board 410 generates a corresponding air volume decrease signal. On the contrary, when the retaining wall 320 rotates counterclockwise into the U-shaped groove and first blocks the second light outlet 422, the grating 420 judges that the air volume needs to be increased, and the PCBA board 410 generates a corresponding air volume increase signal.

[0061] Further, as the curved surface block 310 continues to rotate, multiple retaining walls 320 continuously rotate into the U-shaped groove, so that the grating 420 continuously generates air volume signals and continuously transmits the air volume signals to the control module, so that the control module can adjust the air volume size of the air conditioner and control the degree of increase or decrease of the air volume. Thus, according to the rotation degree of the curved surface block 310, the PCBA board 410 can generate a corresponding air volume signal to achieve precise adjustment of the air volume size.

[0062] Combined withFigures 5 to 11 , in order to enable users to accurately control the rotation degree of the curved surface block 310 to control the increase or decrease of the air volume, and at the same time improve the user's operation feel, a number of continuously and evenly distributed curved surface adjustment gears 330 are provided on the side circumference of the curved surface block 310, and a gear spring top pin 340 that cooperates with the curved surface adjustment gear 330 is also provided in the housing 100. The curved surface adjustment gear 330 and the gear spring top pin 340 can cooperate to realize the rotation degree prompt of the curved surface block 310.

[0063] Specifically, the curved surface adjustment gear 330 is configured as an arc-shaped curved surface. A number of curved surface adjustment gears 330 are continuously distributed on the side circumference of the curved surface block 310 to form a continuous wavy peripheral surface. The gear spring top pins 340 are symmetrically arranged on both sides of the curved surface block 310 respectively and are elastically abutted and cooperated with the curved surface adjustment gear 330. When the curved surface block 310 rotates to drive the curved surface adjustment gear 330 to rotate synchronously, the gear spring top pin 340 will be compressed under the abutting force of the previous curved surface adjustment gear 330, and will recover and extend under its own elastic force, and at the same time act on the next curved surface adjustment gear 330 with the elastic force and abut against the next curved surface adjustment gear 330.

[0064] Therefore, during the rotation of the curved surface block 310, the gear spring top pin 340 will continuously and continuously switch between the compressed state and the restored state, and continuously act on the next curved surface adjustment gear 330 with the elastic force. The generated elastic force will be transmitted to the drive shaft 220, and then transmitted from the drive shaft 220 to the upper button 211, so that the user can sense the elastic force, realize the gear adjustment feel, thereby prompting the rotation degree of the curved surface block 310, enabling the user to accurately control the rotation of the curved surface block 310 to accurately adjust the air volume, and improving the user's use experience.

[0065] The air volume adjustment module 300 thus constituted cooperates with the grating 420 on the first surface 401 of the PCBA board 410 in the signal trigger module 400 through the curved surface block 310 and the retaining wall 320 to realize the adjustment and judgment of the air volume size, generate a corresponding air volume signal, so that the control module can accurately adjust the air volume of the air conditioner. At the same time, the gear adjustment feel is realized through the cooperation of the curved surface adjustment gear 330 and the gear spring top pin 340, so that the user can accurately control the air volume adjustment.

[0066] Combined with Figure 3, in order to integrate the air volume adjustment and the wind direction adjustment on the adjustment button module 200 to improve the adjustment efficiency, a wind direction adjustment module 500 is provided below the signal trigger module 400, and a driving slot 411 is also provided on the PCBA board 410 of the signal trigger module 400, so that the driving shaft 220 of the adjustment button module 200 can pass through the driving slot 411 and cooperate with the wind direction adjustment module 500 to drive the wind direction adjustment module 500 to move synchronously, so that the wind direction adjustment module 500 cooperates with the second surface 402 of the signal trigger module 400 to generate a wind direction signal and realize the adjustment of the wind direction.

[0067] Combined with Figure 9 , specifically, the driving slots 411 on the PCBA board 410 are configured to be cross-shapedly distributed, so that the driving shaft 220 can pass through the driving slots 411 and axially and radially move in the driving slots 411 to drive the wind direction adjustment module 500 to move synchronously axially and radially.

[0068] Combined with Figure 12 and Figure 13 , correspondingly, the wind direction adjustment module 500 is composed of a slider 510, and a wind direction cavity capable of accommodating the driving shaft 220 therein is formed in the middle of the slider 510, so that the driving shaft 220 passes through the driving slot 411 and then passes through the wind direction cavity, so that the driving shaft 220 axially and radially moves in the driving slot 411 and can drive the slider 510 to move synchronously through the wind direction cavity.

[0069] Furthermore, trigger fingers 520 are respectively provided at both end regions of the top surface of the slider 510, and a plurality of contacts 430 are distributed at both end regions of the second surface 402 of the PCBA board 410, so that when the driving shaft 220 drives the slider 510 to move and drives the trigger fingers 520 to move synchronously, the trigger fingers 520 can move to contact and cooperate with the contacts 430, so that the PCBA board 410 generates a wind direction signal.

[0070] Combined with Figure 12 and Figure 14 , as an example, in this embodiment, a first trigger finger 521 and a second trigger finger 522 are respectively provided at both end regions of the top surface of the slider 510, the first trigger finger 521 and the second trigger finger 522 are respectively axially and radially distributed, correspondingly, a first group of contacts 431 and a second group of contacts 432 are respectively distributed at both end regions of the second surface 402 of the PCBA board 410 corresponding to the first trigger finger 521 and the second trigger finger 522, and a plurality of contacts in the first group of contacts 431 and the second group of contacts 432 are cross-shapedly distributed, so that when the driving shaft 220 axially and radially moves in the driving slot 411 and drives the slider 510 to move synchronously axially and radially, the first trigger finger 521 and the second trigger finger 522 can respectively contact and cooperate with any contact in the first group of contacts 431 and the second group of contacts 432, so that the PCBA board 410 can generate a wind direction signal corresponding to the contact.

[0071] Here, the distribution scheme of the contact 430 can also be adaptively adjusted according to the size of the trigger finger 520, the moving stroke of the slider 510, etc., as long as it satisfies that the contact 430 corresponds to the trigger finger 520, and the trigger finger 520 can contact any contact 430 to generate a corresponding wind direction signal.

[0072] Combined Figure 15 , further, each contact 430 corresponds to a different resistance value, so that when the trigger finger 520 of the slider 510 contacts the contacts 430 at different positions, the PCBA board 410 can generate wind direction signals corresponding to different resistance values, so that the control module receives the wind direction signals of this resistance value and correspondingly adjusts the blade rotation angle to accurately adjust the wind direction.

[0073] Combined Figure 16 , in order to ensure that the slider 510 can move synchronously and stably with the drive shaft 220, this air outlet adjustment switch further includes a base 600. A chute 610 is provided on the base 600, and a sliding seat 530 is provided on the bottom surface of the slider 510, so that the slider 510 can move smoothly in the chute 610 through the sliding seat 530, improving the stability of the wind direction signal.

[0074] As an example, in this embodiment, the chute 610 is configured in a cross-shaped distribution, and the drive shaft 220 can drive the slider 510 to move along the axial and radial directions of the chute 610 through the sliding seat 530, improving the matching precision between the trigger finger 520 of the slider 510 and the contact 430, thereby improving the adjustment stability and accuracy of the wind direction.

[0075] The wind direction adjustment module 500 thus constituted realizes the precise adjustment of the wind direction through the cooperation of the slider 510, the trigger finger 520 and the contacts 430 on the second surface 402 of the PCBA board 410 in the signal trigger module 400, and ensures the stability of the wind direction signal through the cooperation of the sliding seat 530 and the chute 610 of the base 600.

[0076] Further, a groove 620 for cooperating with the drive shaft 220 is also provided in the middle area of the base 600. The groove 620 is configured as a curved surface with a cross-shaped distribution. A moving spring top pin 223 is provided at the bottom of the drive shaft 220, so that the moving spring top pin 223 is elastically abutted and cooperated with the groove 620. When the drive shaft 220 moves, the moving spring top pin 223 is elastically abutted against the groove 620 to improve the cooperation stability between the drive shaft 220 and the air volume adjustment module 300 and the wind direction adjustment module 500.

[0077] Meanwhile, the driving slot holes 411 and contacts 430 of the signal triggering module 400, and the sliding slots 610 and grooves 620 of the base 600 are all configured to be distributed in a cross shape to cooperate with each other to guide the moving direction of the driving shaft 220, so that the driving shaft 220 can rotate, and can also move axially and radially smoothly, and ensure the close cooperation between the air volume adjustment module 300 and the air direction adjustment module 500 with the signal triggering module 400 respectively, so that the rotation of the adjustment button module 200 can adjust the air volume, and the axial and radial movement can adjust the air direction, thereby realizing the integration of air volume and air direction adjustment of the adjustment button module 200 and improving the adjustment efficiency.

[0078] Further, the air volume adjustment module 300 and the air direction adjustment module 500 cooperate with the first surface 401 and the second surface 402 of the signal triggering module 400 respectively to generate air volume signals and air direction signals corresponding to different adjustment degrees, so as to accurately adjust the air volume and air direction and improve the adjustment accuracy.

[0079] This air outlet adjustment switch further includes a control module, which can be set on a vehicle-mounted controller or a remote controller, is connected to the air volume adjustment module 300 and the air direction adjustment module 500, and is configured to receive the air volume signals and air direction signals generated by the air volume adjustment module 300 and the air direction adjustment module 500, and correspondingly adjust the air volume and air direction of the air conditioner, so as to improve the adjustment efficiency and adjustment accuracy.

[0080] Further, in combination with Figure 2 , this air outlet adjustment switch further includes a decorative ring 700. The decorative ring 700 is sleeved on the outside of the housing 100 and cooperates with the adjustment button module 200 to enhance the use experience of the adjustment button module 200.

[0081] The following is an example to illustrate the working process of the present invention in specific applications. It should be noted here that the content described is only a specific application example of this solution and does not limit this solution.

[0082] The user rotates the upper button 211 of the adjustment button module 200, so that the upper button 211 drives the driving shaft 220 to rotate synchronously, so that the curved surface block 310 of the air volume adjustment module 300 rotates synchronously around the driving shaft 220. At the same time, the curved surface adjustment gears 330 on the side circumference of the curved surface block 310 are elastically abutted and cooperated with the gear spring top pins 340 during the rotation process, so that the gear spring top pins 340 continuously switch between the compressed state and the restored state, and continuously apply the elastic force to the next curved surface adjustment gear 330. The generated elastic force will be transmitted to the driving shaft 220 and then from the driving shaft 220 to the upper button 211, so that the user can sense the elastic force and realize the gear adjustment feel, so that the user can accurately control the rotation degree of the curved surface block 310.

[0083] During this process, the drive shaft 220 drives the retaining wall 320 at the bottom of the curved surface block 310 to rotate synchronously into the grating 420 on the first surface 401 of the signal trigger module 400, blocking the grating 420. When the grating 420 is in a blocked state, the grating 420 determines that the air volume needs to be switched.

[0084] If the retaining wall 320 rotates clockwise into the grating 420 and first blocks the first light outlet 421, the grating 420 determines that the air volume needs to be decreased, and the PCBA board 410 generates a corresponding air volume decrease signal. Conversely, if the retaining wall 320 rotates counterclockwise into the grating 420 and first blocks the second light outlet 422, the grating 420 determines that the air volume needs to be increased, and the PCBA board 410 generates a corresponding air volume increase signal.

[0085] The control module receives the air volume signal and correspondingly adjusts the air volume of the air conditioner.

[0086] Further, the upper button 211 of the user control adjustment button module 200 moves axially and radially, so that the upper button 211 drives the drive shaft 220 to move axially and radially synchronously, causing the drive shaft 220 to drive the slider 510 of the air direction adjustment module 500 to move axially and radially synchronously along the chute 610 of the base 600 through the sliding seat 530.

[0087] At the same time, the slider 510 drives the trigger finger 520 to move synchronously, so that the trigger finger 520 contacts any contact 430 on the second surface 402 of the signal trigger module 400. Since each contact 430 corresponds to a different resistance value, when the trigger finger 520 contacts the contacts 430 at different positions, the PCBA board 410 can generate air direction signals corresponding to different resistance values.

[0088] The control module receives the air direction signal corresponding to the resistance value and correspondingly adjusts the blade rotation angle to precisely adjust the air direction.

[0089] The air outlet adjustment switch provided by the present invention integrates air volume adjustment and air direction adjustment through the mutual cooperation of the adjustment button module 200, the air volume adjustment module 300, the signal trigger module 400, the air direction adjustment module 500 and the control module. The air volume and air direction are adjusted by different motion states of the adjustment button module 200, improving the adjustment efficiency, and the adjustment is performed through a signal transmission method to improve the adjustment accuracy.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
