Description

Technical Field

[0001] The present invention relates to the field of air-conditioning vents, and in particular to a hidden air-conditioning vent assembly and a vehicle. Background Art

[0002] Most existing concealed air conditioning vents take up a lot of space. This is primarily due to the use of a single-piece air deflector in the air inlet duct to adjust the airflow up and down. The width of the air deflector must be greater than half the height of the upper and lower inner walls of the air inlet duct to achieve a closed upper or lower air duct. Since the width of the air deflector cannot be reduced, the size of the air outlet cannot be reduced. Currently, vehicle design concepts are increasingly leaning towards simplicity, with smaller interior space requirements, and smaller air outlet dimensions. Therefore, further streamlining the air outlet assembly structure is a technical issue that deserves considerable attention. Summary of the Invention

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] For example, see the attached Figure 1-13 A hidden air-conditioning outlet assembly includes an outer shell 100, an inner shell 200, an air direction adjustment mechanism 300, and a control mechanism; the inner shell 200 is arranged in the outer shell 100 and divides the air duct space inside the outer shell 100, and the air duct space includes a first air channel 110, a second air channel 120, and an air intake channel 130; the air direction adjustment mechanism 300 includes a first air guide 310 and a second air guide 320, the first air guide 310 is rotatably arranged in the first air channel 110, and the ventilation volume of the first air channel 110 is adjusted according to the position of the first air guide 310; the second air guide 320 is rotatably arranged in the second air channel 120, and the ventilation volume of the second air channel 120 is adjusted according to the position of the second air guide 320;

[0031] The control mechanism includes a dial button assembly 400, a first motion conversion mechanism 500, and a second motion conversion mechanism 600, which are connected in sequence. The dial button assembly 400 includes a dial button member 410 and a shift fork member 420 that rotate synchronously in the same direction. The first motion conversion mechanism 500 is disposed inside the inner housing 200 and includes a crank member 510 and a connecting rod member 520. The second motion conversion mechanism 600 is disposed outside the outer housing 100 and includes a translation member 610, a first rotation member 620, and a second rotation member 630.

[0032] The crank member 510 is rotatably disposed in the inner housing 200 and includes a first rotating portion 511 and a second rotating portion 512; the connecting rod member 520 includes a first connecting portion 521 and a second connecting portion 522 in the shape of a ball head; the fork member 420 is connected to the first rotating portion 511 of the crank member 510, and the second rotating portion 512 of the crank member 510 is connected to the first connecting portion 521 of the connecting rod member 520 and has a first connecting hole adapted to the ball head shape of the first connecting portion 521; the second connecting portion 522 of the connecting rod member 520 is connected to the translation member 610, and the translation member 610 has A second connecting hole is adapted to the shape of the ball head of the second connecting portion 522; the first connecting portion 521 of the connecting rod 520 is restricted by the crank member 510 to only allow curved movement, and the second connecting portion 522 is restricted by the translation member 610 to only allow linear movement; in this embodiment, due to various precision errors in manufacturing, the rotational surface of the crank member 510 and the translational surface of the translation member 610 are most likely not parallel in three-dimensional space, and there is a slight angular difference between the two surfaces. The connecting rod 520 is connected to the crank member 510 and the translation member 610 respectively through the ball head, which can compensate for the assembly and movement effects caused by the two angular differences;

[0033] The outer shell 100 has a guide rail groove 140 with a linear travel on the outside, and the translation member 610 has a slider 615 that is adapted to the guide rail groove 140 and slides in the guide rail groove 140. The second connecting portion 522 of the connecting rod member 520 is connected to the slider 615 to drive the slider 615 to move linearly in the guide rail groove 140; the first rotating member 620 is connected to the first air guide member 310 and can drive the first air guide member 310 to rotate synchronously; the second rotating member 630 is connected to the second air guide member 320 and can drive the second air guide member 320 to rotate synchronously.

[0034] When the toggle button 410 is pushed upward by an external force in the intermediate state, the toggle button 410 drives the fork member 420 to rotate clockwise. The fork member 420 rotates clockwise and drives the crank member 510 in the inner housing 200 to rotate counterclockwise. The crank member 510 rotates counterclockwise and drives the first connecting portion 521 of the connecting rod 520 to move upward to the right, thereby driving the second connecting portion 522 of the connecting rod 520 to move linearly to the right. The second connecting portion 522 of the connecting rod 520 moves linearly to the right and drives the translation member 610 outside the outer housing 100 to move linearly to the right. The translation member 610 moves linearly to the right and drives the first rotating member 620 to rotate counterclockwise. The first rotating member 620 rotates counterclockwise and drives the first air guide member 310 in the first air channel 110 to rotate clockwise, thereby adjusting the ventilation volume of the first air channel 110.

[0035] Similarly, when the button member 410 is pushed downward by an external force in the intermediate state, the button member 410 drives the fork member 420 to rotate synchronously in the same direction counterclockwise. The fork member 420 rotates counterclockwise while driving the crank member 510 to rotate clockwise. The crank member 510 rotates clockwise while driving the first connection portion 521 of the connecting rod member 520 to move to the upper left, thereby driving the second connection portion 522 of the connecting rod member 520 to move linearly to the left. The second connection portion 522 of the connecting rod member 520 moves linearly to the left while driving the translation member 610 to move linearly to the left. The translation member 610 moves linearly to the left while driving the second rotating member 630 to rotate clockwise. The second rotating member 630 rotates clockwise while driving the second air guide member 320 to rotate clockwise, thereby adjusting the ventilation volume of the second air channel 120.

[0036] This embodiment only discloses a specific structure of the second motion conversion mechanism 600. The relationship between the moving direction of the translation member 610 and the rotation directions of the first rotating member 620 and the second rotating member 630 can vary according to the specific structure and is not limited to the relationship disclosed in this embodiment.

[0037] The up and down air outlet control principle of the air conditioner air outlet assembly in this embodiment (the direction in this embodiment can refer to Figure 6 Center air outlet (up, down, left, and right):

[0038] Horizontal air flow, when the dial button 410 is Figure 1-2 When the first air guide 310 and the second air guide 320 are in the middle state, the corresponding positions of the first air guide 310 and the second air guide 320 are as shown in FIG. Figure 6 As shown, after the airflow passes through the air inlet channel 130, it is divided into the first air channel 110 and the second air channel 120 due to the presence of the inner shell 200. At this time, since the first air guide 310 and the second air guide 320 do not block the first air channel 110 and the second air channel 120, the airflows entering the first air channel 110 and the second air channel 120 are almost the same. The two airflows pass through the first air channel 110 and the second air channel 120 and then merge. Since the two airflows are of the same size, the merged airflow flows out in a horizontal direction.

[0039] The air flows upwards, and when the user turns the dial button 410, the air flows upwards. Figure 7 When the first air guide 310 and the second air guide 320 are in the upward state, the corresponding positions of the first air guide 310 and the second air guide 320 are as shown in FIG. Figure 8As shown, at this time, since the first air guide 310 reduces the ventilation cross-section of the first air channel 110 or directly closes the first air channel 110, and the second air guide 320 does not block the second air channel 120, most or all of the airflow flows to the second air channel 120 after passing through the air inlet channel 130, and a small part or no airflow flows to the first air channel 110. The two airflows pass through the first air channel 110 and the second air channel 120 and then merge. Since the airflow flowing along the second air channel 120 accounts for a larger proportion, the merged airflow eventually flows out in an upward direction;

[0040] Downward airflow, when the user turns the dial button 410 to make it Figure 9 When the first air guide 310 and the second air guide 320 are in the downward state, the corresponding positions of the first air guide 310 and the second air guide 320 are as shown in FIG. Figure 10 As shown, at this time, since the second air guide 320 reduces the ventilation cross-section of the second air channel 120 or directly closes the second air channel 120, and the first air guide 310 does not obstruct the first air channel 110, most or all of the airflow flows to the first air channel 110 after passing through the air intake channel 130, and a small part or no airflow flows to the second air channel 120. The two airflows pass through the first air channel 110 and the second air channel 120 and then merge. Since the airflow flowing along the first air channel 110 accounts for a large proportion, the merged airflow eventually flows out in a downward direction.

[0041] In this embodiment, the hidden air-conditioning outlet assembly is provided with the wind direction adjustment mechanism 300, namely the first air guide 310 and the second air guide 320, respectively arranged in the first air channel 110 and the second air channel 120, rather than in the air intake channel 130. Therefore, the length of the air intake channel 130 can be shortened, thereby reducing the space occupied by the outlet assembly as a whole. At the same time, the first motion conversion mechanism 500 is arranged in the inner shell 200, thereby improving the utilization rate of the internal space of the outlet. The second motion conversion mechanism 600 has stable transmission and simple structure.

[0042] In this embodiment, the translation member 610 drives the first rotating member 620 and the second rotating member 630 to rotate by means of gear transmission. Specifically, the first rotating member 620 includes a first gear portion 621 provided on the outer ring, and a first position-limiting straight groove 622 and a first auxiliary curved groove 623 provided on the end surface and connected; the second rotating member 630 includes a second gear portion 631 provided on the outer ring, and a second position-limiting straight groove 632 and a second auxiliary curved groove 633 provided on the end surface and connected; the translation member 610 includes a first rack portion 611, a second rack The first rack portion 611 is used to engage with the first gear portion 621 to drive the first rotating member 620, and the second rack portion 612 is used to engage with the second gear portion 631 to drive the second rotating member 630. At most one pair of gear portions and rack portions are engaged at the same time. The first limiting post 613 can move in the first limiting straight groove 622 and the first auxiliary curved groove 623, and the second limiting post 614 can move in the second limiting straight groove 632 and the second auxiliary curved groove 633.

[0043] When the first gear portion 621 meshes with the first rack portion 611 and rotates, the first limiting post 613 moves in the first auxiliary curved groove 623 and assists in driving the first rotating member 620 to rotate, while the second limiting post 614 moves in the second limiting straight groove 632 and limits the rotation of the second rotating member 630; when the second gear portion 631 meshes with the second rack portion 612 and rotates, the second limiting post 614 moves in the second auxiliary curved groove 633 and assists in driving the second rotating member 630 to rotate, while the first limiting post 613 moves in the first limiting straight groove 622 and limits the rotation of the first rotating member 620. In this embodiment, the transmission using gear transmission is more accurate and efficient; the main function of the limiting straight groove is to keep the position of the rotating member and the air guide member unchanged when the gear and rack are no longer meshed; the main function of the auxiliary curved groove is similar to that of the gear and is also used for transmission. In this embodiment, it only plays an auxiliary role.

[0044] Since the axis of the fork member 420 and the axis of the crank member 510 are not on the same axis, relative displacement will occur in the left and right directions during rotation. Therefore, in this embodiment, the fork member 420 has a notch portion, and the first rotating portion 511 of the crank member 510 has a connecting rod portion extending into the notch portion; when the fork member drives the crank member to rotate through the notch portion and the connecting rod portion, the connecting rod portion slides relatively in the notch portion along the depth direction of the notch portion.

[0045] Although the present invention has been described with reference to preferred embodiments, it will be understood by those skilled in the art that it is not limited to the above embodiments and that various changes in form and details may be made within the scope of the claims.
