Description

Technical Field

[0001] The present invention relates to the technical field of automobile accessories, and in particular to a manual hidden air outlet. Background Art

[0002] Hidden air outlets are generally hidden in the panels or decorative parts inside the car. This type of air outlet design has certain advantages in appearance, space utilization, air conditioning effect, etc., and is a common design element in modern car design. Since the air outlets need to be set in the panels or decorative parts inside the car, the requirements for the space occupied by the air outlets are particularly stringent.

[0003] China's utility model patent "A Centralized Control Type Automobile Air Conditioner Concealed Air Outlet Structure" (CN211054888U) discloses a technical solution for a concealed air outlet. Its main structure includes a housing, an air guide mechanism, and a control mechanism. The air guide mechanism can be controlled to swing up and down and left and right through the control mechanism. However, the control mechanism includes multiple parts such as a knob, a universal assembly, a main transmission assembly, and a secondary transmission assembly. These parts themselves have a complex structure, and the housing structure that carries these parts also becomes complex. For example, the driven size and the intermediate gear connected to the housing require additional processing of the gear shaft receiving hole and the gear protection structure on the housing. The connecting rod placed in the shell requires a corresponding load-bearing structure in the shell, resulting in high manufacturing costs for the control mechanism itself and the shell; and because the control mechanism has many and complex parts, it occupies a large space. For example, a ball head rotary rod and a shift fork are provided along the width direction of the air outlet, which reduces the available space in the width of the air outlet body, thereby affecting the air output; in addition, this control mechanism also has the problem of poor stability. During the driving of the car, it is easy for the coordination between the parts to fail due to bumps. For example, looseness between multiple meshing gears may cause the left and right air adjustment function to fail, and looseness of the shift fork structure may cause the up and down air adjustment function to fail. Summary of the Invention

[0004] The problem to be solved by the present invention is to provide a manual hidden air outlet with low manufacturing cost of the control mechanism itself and the shell, less space occupied by the control mechanism and better stability of the control mechanism.

[0005] The technical solution adopted by the present invention to solve the above-mentioned problem is: a manual hidden air outlet, comprising a housing, a plurality of upper and lower air-regulating blades and a plurality of left and right air-regulating blades disposed in the housing, and an adjustment mechanism; the housing comprises an outlet, and the straight line on which the rotation axes of the left and right air-regulating blades lie is arranged to be parallel to the upper and lower connecting line of the outlet; the adjustment mechanism comprises an intermediate rod disposed on one side of the housing, a shifting block structure movably connected to the intermediate rod, a left and right adjustment structure disposed on the intermediate rod, and a vertical adjustment structure disposed at one end of the shifting block structure;

[0006] The intermediate rod includes a vertical rod arranged parallel to the straight line where the left and right air-adjusting blade rotation axes are located, and the upper and lower ends are arranged on the housing, and a horizontal rod fixedly connected to the upper end of the vertical rod and perpendicular to the vertical rod; the shift block structure includes a shift rod that can be moved up and down along the central axis of the vertical rod, and at least one driving block sleeved on the outer wall of the shift rod; the up and down adjustment structure includes a gear set and a transmission plate; one end of the transmission plate is connected to the driving block, and the other end is connected to the gear set; the thickness direction of the gear set, the thickness direction of the transmission plate, and the thickness direction of the driving block are consistent with the width direction of the housing;

[0007] When the shift rod rotates around the vertical rod, the driving block drives the horizontal rod to rotate synchronously through the vertical rod, and then drives the multiple left and right air-adjusting blades to swing through the left and right adjustment structure; when the shift rod moves up and down along the central axis of the vertical rod, the driving block drives the gear set to rotate through the transmission plate, and then drives the multiple upper and lower air-adjusting blades to swing.

[0008] Compared with the prior art, the present invention includes a shell, multiple upper and lower air-regulating blades, multiple left and right air-regulating blades and an adjusting mechanism.

Under this arrangement, the structure of the adjustment mechanism is more compact and takes up less space in the width direction of the shell. When the toggle lever rotates around the vertical rod, the transmission of the vertical rod, the horizontal rod, and the left and right adjustment structure can drive the multiple left and right air-adjusting blades to swing. When the toggle lever moves up and down along the central axis of the vertical rod, the driving block, the transmission plate, and the gear set rotate to allow the multiple upper and lower air-adjusting blades to swing. Under this arrangement, one set of adjustment mechanism can realize the adjustment of the upper and lower and left and right sets of blades, and the adjustment mechanism uses fewer parts and occupies less space, thereby making the structure for carrying the adjustment mechanism on the shell less, thereby reducing the manufacturing cost of the shell, and because the joint mechanism uses fewer parts and the transmission coordination between the various parts is also less, the transmission loss is smaller, the transmission is more stable, and the probability of damage during long-term bumpy driving of the car is smaller.

[0031] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0032] See also Figure 1 、 Figure 2 、 Figure 3 A manual concealed air outlet comprises a housing 1, a plurality of vertical air-regulating blades 2 and a plurality of horizontal air-regulating blades 3 disposed within the housing 1, and an adjustment mechanism 4. The housing 1 comprises an outlet 11, and the straight line on which the rotation axes of the horizontal air-regulating blades 3 lie is arranged to be parallel to a vertical line connecting the outlet 11. The adjustment mechanism 4 comprises an intermediate rod 41 disposed on one side of the housing 1, a shifting block structure 42 movably connected to the intermediate rod 41, a horizontal adjustment structure 43 disposed on the intermediate rod 41, and a vertical adjustment structure 44 disposed at one end of the shifting block structure 42.

[0033] The intermediate rod 41 includes a vertical rod 411 arranged parallel to the straight line where the rotation axes of the left and right air-regulating blades 3 are located, and the upper and lower ends are arranged on the housing 1, and a horizontal rod 412 fixedly connected to the upper end of the vertical rod 411 and perpendicular to the vertical rod 411; the shifting block structure 42 includes a shifting rod 421 that can move up and down along the central axis of the vertical rod 411, and at least one driving block 422 sleeved on the outer wall of the shifting rod 421; the up and down adjustment structure 44 includes a gear set 441 and a transmission plate 442; one end of the transmission plate 442 is connected to the driving block 422, and the other end is connected to the gear set 441; the thickness direction of the gear set 441, the thickness direction of the transmission plate 442, and the thickness direction of the driving block 422 are consistent with the width direction of the housing 1;

[0034] When the lever 421 rotates around the vertical rod 411, the driving block 422 drives the horizontal rod 412 to rotate synchronously through the vertical rod 411, and then drives the multiple left and right air-adjusting blades 3 to swing through the left and right adjustment structure 43; when the lever 421 moves up and down along the central axis of the vertical rod 411, the driving block 422 drives the gear set 441 to rotate through the transmission plate 442, and then drives the multiple up and down air-adjusting blades 2 to swing.

[0035] When in actual use, the present invention includes a shell 1, a plurality of upper and lower air-regulating blades 2, a plurality of left and right air-regulating blades 3 and an adjusting mechanism 4, the adjusting mechanism 4 includes an intermediate rod 41, a shift block structure 42, a left and right adjusting structure 43 and an upper and lower adjusting structure 44, the intermediate rod 41 includes a vertical rod 411 and a horizontal rod 412; wherein, the upper and lower ends of the intermediate rod 41 are arranged on the shell 1, so that the intermediate rod 41 serving as the adjustment hub obtains a more stable connection; the straight line where the rotating shafts of the left and right air-regulating blades 3 are located is parallel to the upper and lower connecting lines of the outlet 11, the vertical rod 411 is parallel to the straight line where the rotating shafts of the left and right air-regulating blades 3 are located, and the horizontal rod 412 is perpendicular to the straight line where the rotating shafts of the left and right air-regulating blades 3 are located. This position layout can make left and right adjustment without adding components for adjusting the direction, so that the structure is relatively simple, the number of components is relatively small, and the transmission is stable; the shift block structure 42 includes a shift rod 421 and a driving block 422, the upper and lower adjusting structure 44 includes a gear set 441 and a transmission plate 442, the thickness direction of the gear set 441, the thickness direction of the transmission plate 442 and the driving block The thickness direction of 422 is consistent with the width direction of the shell 1. Under this setting, the structure of the adjustment mechanism 4 is more compact and takes up less space in the width direction of the shell 1; when the lever 421 rotates around the vertical rod 411, the transmission of the vertical rod 411, the horizontal rod 412, and the left and right adjustment structure 43 can drive multiple left and right air-adjusting blades 3 to swing. When the lever 421 moves up and down along the central axis of the vertical rod 411, the driving block 422, the transmission plate 442, and the gear set 441 rotate to swing multiple up and down air-adjusting blades 2. Under this setting, one set of adjustment mechanism 4 can realize the adjustment of two groups of blades, up and down, left and right, and the adjustment mechanism 4 uses fewer parts and takes up less space, which in turn makes the structure for carrying the adjustment mechanism 4 on the shell 1 less, thereby reducing the manufacturing cost of the shell 1, and because the joint mechanism 4 uses fewer parts and the transmission coordination between the various parts is also less, the transmission loss is smaller, the transmission is more stable, and the probability of damage during long-term bumpy driving of the car is smaller.

[0036] Further, such as Figure 4 As shown, the upper and lower connecting lines of the outlet 11 are marked as the A-axis, the straight line where the rotating axes of the left and right air-regulating blades 3 are located is the B-axis, and the central axis of the vertical rod 411 is the C-axis. The A-axis, B-axis and C-axis are parallel to each other, so that the rotational movement of the C-axis can be converted into the rotational movement of the B-axis without the need for additional angle adjustment parts, which is beneficial to reducing the number of parts and the overall size of the air outlet.

[0037] Further, such as Figure 6As shown, the thickness direction of the gear set 441, the thickness direction of the transmission plate 442 and the thickness direction of the drive block 422 are the smallest compared to their respective length directions, width directions and other dimensions. Therefore, when the thickness directions of the three are consistent with the width direction of the shell 1 at the same time, the size of the shell 1 in the width direction is the smallest, so that the space occupied by the entire hidden air outlet in the width direction of the car interior is also the smallest.

[0038] Please continue reading Figure 3 、 Figure 5 , wherein the shell 1 includes a U-shaped protective shell 12 arranged on one side; the U-shaped protective shell 12 has an accommodating cavity 121 arranged inside, and an opening 122 arranged on the side of the accommodating cavity 121 close to the dial block structure 42; the U-shaped protective shell 12 also includes limiting holes 123 arranged at the upper and lower ends of the opening 122; the two limiting holes 123 are used to limit the upper and lower ends of the vertical rod 411 so as to limit the up and down movement of the vertical rod 411 and allow the vertical rod 411 to rotate.

[0039] Specifically, the accommodating cavity 121 of the U-shaped protective shell 12 provides installation space for the up and down adjustment structure 44 and adjusts the structure 44 up and down, so as to reduce the probability of damage to the up and down adjustment structure 44; the opening 122 on the side of the accommodating cavity 121 close to the shift block structure 42 is used to provide an entrance to the accommodating cavity 121 for the driving block 422, so that the shift block structure 42 controls the up and down adjustment structure 44; the limiting holes 123 arranged at the upper and lower ends of the opening 122 are used to respectively install the upper and lower ends of the vertical rod 411, so that the vertical rod 411 only obtains the freedom to rotate around the central axis of the limiting hole 123, thereby stably controlling the movement of the up and down adjustment structure 44.

[0040] Please see further Figure 5 , wherein the vertical rod 411 includes an upper limit end 4111 provided at the upper end, a lower limit end 4112 provided at the lower end, and a transmission rod 4113 provided between the upper limit end 4111 and the lower limit end 4112; the upper limit end 4111 cooperates with one of the limit holes 123, and the lower limit end 4112 cooperates with the other limit hole 123; Figure 5 In the illustrated embodiment, the lower limit end 4112 includes two spring sheets that can be deformed from both sides to the middle. During installation, the lower limit end 4112 first passes through the limit hole 123 at the upper end and then passes through the limit hole 123 at the lower end through the deformation of the spring sheets. At this time, the upper limit end 4111 just abuts against the edge of the limit hole 123 at the upper end, and the two spring sheets of the lower limit end 4112 abut against the edge of the limit hole 123 at the lower end, so that the vertical rod 411 cannot move up and down, but can only rotate around the central axis of the limit hole 123.

[0041] Please see further Figure 5, wherein the transmission rod 4113 includes a main rod body 41131 and a sub-rod body 41132 arranged on one side of the main rod body 41131; the driving block 422 is provided in two pieces and is connected to the transmission rod 4113 in upper and lower positions; the driving block 422 has a main driving hole 4221 and a sub-driving hole 4222; the main rod body 41131 passes through the main driving hole 4221, and the sub-rod body 41132 passes through the sub-driving hole 4222; one end of the transmission plate 442 is movably connected between the two driving blocks 422 arranged above and below.

[0042] Specifically, by setting the upper and lower driving blocks 422, the movement of the entire shifting block structure 42 moving up and down along the transmission rod 4113 is more stable. On this basis, by connecting the upper and lower driving blocks 422 with the transmission plate 442, the movement of the shifting block structure 42 driving the transmission plate 442 up and down is more stable, thereby improving the sensitivity of the up and down air adjustment. In addition, the driving block 422 has a main driving hole 4221 and a secondary driving hole 4222, and the cross-sections of the main driving hole 4221 and the secondary driving hole 4222 are They are all rectangular, and the transmission rod 4113 includes a main rod body 41131 and a sub-rod body 41132, and the cross-sections of the main rod body 41131 and the sub-rod body 41132 are also rectangular. Through the cooperation of the main rod body 41131 and the main driving hole 4221 and the sub-rod body 41132 and the sub-driving hole 4222, when the shift block structure 42 rotates, it can drive the vertical rod 411 to rotate around the central axis of the limiting hole 123 with a greater torque, thereby making the swing of the left and right adjustment structure 43 more stable and improving the sensitivity of the left and right air adjustment.

[0043] Please continue reading Figure 5 、 Figure 7 、 Figure 9 , wherein the cross bar 412 is set at the upper limit end 4111; the left and right adjustment structure 43 includes a first transition rod 431, a second transition rod 432 and a left and right adjustment drive plate 433; one end of the first transition rod 431 is movably connected to the cross bar 412, and the other end is movably connected to the second transition rod 432; the second transition rod 432 is set on one of the left and right air-adjusting blades 3; the control shafts of multiple left and right air-adjusting blades 3 are set on the left and right adjustment drive plate 433; when the cross bar 412 rotates, one of the left and right air-adjusting blades 3 is driven to swing through the first transition rod 431 and the second transition rod 432, and then the multiple left and right air-adjusting blades 3 are driven to swing synchronously through the left and right adjustment drive plate 433.

[0044] Specifically, the left and right swinging of multiple left and right air-adjusting blades 3 is achieved by the displacement of the left and right adjustment driving plate 433. Since the middle rod 41 needs to have the function of driving the upper and lower air-adjusting blades 2 and the left and right air-adjusting blades 3 at the same time, the position of the vertical rod 411 is between the upper and lower limit holes 123. In this position, if the cross rod 412 is directly connected to the left and right adjustment driving plate 433, the rotation action of the cross rod 412 cannot be converted into the displacement action of the left and right adjustment driving plate 433. If the cross rod 412 is directly connected to the second transition rod 432, the problem of insufficient adjustment angle will arise. When the first transition rod 431 and the second transition rod 432 are provided at the same time, due to the increase in the adjustment distance, the second transition rod 432 can obtain a larger swing angle, and then the left and right adjustment driving plate 433 obtains a larger displacement distance, and finally the swing amplitude of the left and right air-adjusting blades 3 is larger.

[0045] Please continue reading Figure 3 、 Figure 5 、 Figure 7 , wherein the gear set 441 includes a driving gear 4411 and a driven gear 4412 arranged in the accommodating cavity 121 and meshing with each other; the driven gear 4412 is connected to one of the upper and lower air-regulating blades 2; the driving gear 4411 is connected to the other end of the transmission plate 442; when the two driving blocks 422 move up and down, the transmission plate 442 drives the driven gear 4412 to rotate through the driving gear 4411, thereby driving multiple upper and lower air-regulating blades 2 to swing synchronously.

[0046] During use, when the transmission plate 442 is driven by the two driving blocks 422 to move up and down, the transmission plate 442 first drives the driving gear 4411 to rotate, and then the driving gear 4411 drives the driven gear 4412 to rotate, and finally the driven gear 4412 drives the multiple upper and lower air-regulating blades 2 connected thereto to swing synchronously, thereby realizing the up and down air regulation.

[0047] It is worth mentioning that the swinging of the multiple upper and lower air-regulating blades 2 is achieved by the up and down displacement of the transmission piece 442. Since the intermediate rod 41 needs to have the function of driving the upper and lower air-regulating blades 2 and the left and right air-regulating blades 3 at the same time, the position of the vertical rod 411 is between the upper and lower limit holes 123. In this position, if the transmission piece 442 is directly connected to the driven gear 4412, the up and down displacement of the transmission piece 442 will be insufficient, resulting in the problem of insufficient rotation angle of the driven gear 4412, which in turn leads to insufficient swing amplitude and sensitivity of the upper and lower air-regulating blades 2; when the transmission piece 442 is first connected to the driving gear 4411 and then transferred to the driven gear 4412, the speed matching of the driving gear 4411 and the driven gear 4412 can be used to achieve that the transmission piece 442 can still rotate a larger amplitude when the up and down displacement is small, thereby making the swing amplitude of the upper and lower air-regulating blades 2 larger, and due to the increase in distance, the torque of the transmission piece 442 increases, making the adjustment more sensitive.

[0048] Please see further Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 , wherein the transmission plate 442 includes a rotating shaft 4421, a compensation plate 4422 and a connecting plate 4423 arranged in sequence; the connecting plate 4423 has a sliding groove 44231 arranged through it; the driving gear 4411 includes an extension plate 44111 and a connecting rod 44112 arranged on the extension plate 44111; one end of the connecting rod 44112 is arranged in the sliding groove 44231; the rotating shaft 4421 is arranged between the two driving blocks 422 arranged above and below.

[0049] Specifically, the driving gear 4411 can further increase the torque through the setting of the extension plate 44111, and when the user moves the shift block structure 42 and the up and down adjustment structure 44, the force used can be smaller; the transmission plate 442 is set through the rotating shaft 4421, the compensation plate body 4422 and the connecting plate body 4423, so that one end of it can be rotatably connected to the driving block 422, and the other end has sufficient length to be connected to the connecting rod 44112.

[0050] Please continue reading Figure 6 , wherein the compensation sheet 4422 is configured to bend toward a side away from the gear set 441 so as to form a movable space 1211 between the gear set 441 and the rotating shaft 4421, thereby allowing the rotating shaft 4421 to move toward a side close to the gear set 441 when the driving block 422 rotates.

[0051] Specifically, since the middle rod 41 needs to have the function of driving the upper and lower air-adjusting blades 2 and the left and right air-adjusting blades 3 at the same time, the position of the vertical rod 411 is between the upper and lower limit holes 123. When the user needs to adjust the left and right wind directions, the shift block structure 42 will be moved to rotate the vertical rod 411. At this time, due to the setting of the active space 1211, the transmission plate 442 has enough avoidance space when moving with the rotating shaft 4421 toward the active space 1211. This not only increases the left and right adjustment range, but also avoids collision and interference between parts.

[0052] Please see further Figure 8 , wherein, the connecting rod 44112 includes a sliding rod segment 441121 and a limiting segment 441122 arranged at the end of the sliding rod segment 441121, and the size of the limiting segment 441122 is larger than that of the sliding rod segment 441121; the sliding groove 44231 includes a movable groove segment 442311 and a reaming groove segment 442312 arranged at one end of the movable groove segment 442311, and the size of the reaming groove segment 442312 is larger than that of the movable groove segment 442311; the connecting rod 44112 enters the sliding groove 44231 through the reaming groove segment 442312; when the driving block 422 rotates or moves up and down, the sliding rod segment 441121 moves in the movable groove segment 442311.

[0053] Specifically, since the connecting rod 44112 includes a sliding rod section 441121 and a limiting section 441122, and the size of the sliding rod section 441121 matches the movable slot section 442311, when the user needs to adjust the left and right wind directions, the dial block structure 42 will be dialed to rotate the vertical rod 411, and then the transmission plate 442 will move the rotating shaft 4421 toward the inside and outside of the active space 1211. At this time, the sliding rod section 441121 slides in the movable slot section 442311 to cooperate with the rotation movement of the vertical rod 411, and due to the setting of the limiting section 441122, the sliding rod section 441121 will not fall out when sliding in the movable slot section 442311; the reaming slot section 442312 is used for assembly, so that the sliding rod section 441121 and the limiting section 441122 can pass through.

[0054] Please continue reading Figure 2 , wherein the up and down adjustment structure 44 further includes an up and down swinging fork 443 arranged on the other side of the shell 1, and multiple fork plates 444 arranged on the up and down swinging fork 443; the driven gear 4412 controls the swing of the up and down swinging fork 443 through one of the up and down air regulating blades 2; and multiple fork plates 444 are correspondingly connected to other up and down air regulating blades 2.

[0055] Please continue reading Figure 1 、 Figure 3 、 Figure 9, wherein the shell 1 further includes a limiting protrusion 13; the limiting protrusion 13 is arranged on one side of the second transition rod 432 to limit the swing angle of the second transition rod 432; the shift block structure 42 further includes a shift button 423 arranged on the shift rod 421.
