Description

Technical Field

[0001] This invention belongs to the field of air outlet assembly technology, and relates to a blade adjustment mechanism, an air outlet assembly, and a vehicle. Background Technology

[0002] Air vents are one of the important functional components in a car interior. They can deliver cool or hot air to create a comfortable riding environment. Users can adjust the air volume and angle using the air vent knob. They can also be used in ventilation vents in aircraft, ships, and railway vehicles.

[0003] For example, current car air vents can only deliver air in a concentrated manner. By uniformly adjusting the direction of the air guide vanes, the airflow direction of each sub-vent can be changed simultaneously. This results in poor comfort and cannot achieve a wave-shaped airflow, leaving considerable room for improvement. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a blade adjustment mechanism, an air outlet assembly, and a vehicle.

[0005] The objective of this invention can be achieved through the following technical solution: a blade adjustment mechanism, comprising:

[0006] A drive air guide assembly, which includes a drive shaft, a first connecting rod, and a first air guide plate;

[0007] The drive shaft includes a drive shaft body and a linkage disc located at one end of the drive shaft body; the outer end face of the linkage disc has a first linkage shaft portion, the axis of the first linkage shaft portion is not coaxial with the axis of the drive shaft; one end of the first connecting rod is rotatably connected to the first linkage shaft portion, and the other end is rotatably connected to the first air guide plate; the rotation of the drive shaft can drive the first air guide plate to rotate through the first connecting rod.

[0008] At least one linked air guide assembly, which includes a drive shaft, a second connecting rod, and a second air guide plate;

[0009] The transmission shaft is coaxially arranged with the drive shaft. The transmission shaft includes a transmission shaft body and a main linkage disc and a driven linkage disc located at both ends of the transmission shaft body. The outer end face of the main linkage disc has an outwardly extending second linkage shaft, the axis of which is not coaxial with the axis of the transmission shaft. The outer end face of the driven linkage disc has an inwardly extending linkage groove, the linkage groove having a first side and a second side that can be linked with a first linkage shaft of an adjacent drive shaft or a second linkage shaft of an adjacent transmission shaft. One end of the second connecting rod is rotatably connected to the second linkage shaft, and the other end is rotatably connected to the second air guide plate. The rotation of the transmission shaft can drive the second air guide plate to rotate through the second connecting rod.

[0010] When the drive shaft rotates along the first direction, a first angle difference is formed between each pair of the first air guide plate and each pair of the second air guide plates; when the drive shaft rotates along the second direction, a second angle difference is formed between each pair of the first air guide plate and each pair of the second air guide plates; wherein, the first direction is opposite to the second direction, and the first angle difference is different from the second angle difference.

[0011] In the aforementioned blade adjustment mechanism, the second guide vane and the first guide vane are coaxially arranged; when the drive shaft rotates in the first direction, the axis of the second linkage shaft portion and the axis of the first linkage shaft portion are coaxially related.

[0012] In the blade adjustment mechanism described above, the included angle between the first side and the second side is 90°.

[0013] An air outlet assembly is also provided, including the blade adjustment mechanism mentioned above, and further including: a housing assembly, the housing assembly being provided with a first air duct and a second air duct, the number of second air ducts being two, both of the second air ducts being connected to the first air duct, the driving air guide component and the linkage air guide component being located at the connection between the second air duct and the first air duct.

[0014] In one of the above-mentioned air outlet assemblies, the first air duct is provided with an air wall, and the first air guide plate and each of the second air guide plates are separated from each other by the air wall.

[0015] The aforementioned air outlet assembly also includes an inner blade assembly and an inner blade connecting rod;

[0016] The inner blade assembly includes a blade shaft, inner blades, and a blade linkage. The blade shaft is connected to the housing assembly and can rotate around its own axis. The axis of the blade shaft is perpendicular to the axis of the second air guide plate and the axis of the first air guide plate. There are two inner blades, both of which are connected to the blade shaft and are located in two second air ducts respectively. One end of the blade linkage is connected to the inner blade or the blade shaft, and the other end of the blade linkage is rotatably connected to the inner blade connecting rod.

[0017] When one of the blade shafts rotates, it drives the other blade shafts to rotate synchronously through the inner blade connecting rod.

[0018] In the above-mentioned air outlet assembly, the housing assembly includes an outer shell and an inner shell. The inner shell and the outer shell are located within the outer shell. The first air duct and the second air duct are both located within the outer shell. The two second air ducts are separated by the inner shell. The inner shell is located between the two inner blades. The drive shaft, the transmission shaft, and the blade shaft are rotatably connected to the inner shell.

[0019] In the above-mentioned air outlet assembly, a first driving element is also included. The first driving element is connected to the housing assembly, and the drive shaft body is connected to the first driving element. The first driving element can drive the drive shaft body to rotate.

[0020] In one of the above-mentioned air outlet assemblies, a second driving element is also included. The second driving element is connected to the housing assembly, and the blade shaft is connected to the second driving element. The second driving element can drive the blade shaft to rotate.

[0021] A vehicle is also provided, including the aforementioned air vent assembly.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. By rotating the drive shaft in a first direction, the first linkage shaft portion of the drive shaft and the second linkage shaft portion of the adjacent transmission shaft come into contact with the first side surface, so that a first angle difference is formed between the first air guide plate and each of the second air guide plates; or by rotating the drive shaft in a second direction, the first linkage shaft portion of the drive shaft and the second linkage shaft portion of the adjacent transmission shaft come into contact with the second side surface, so that a second angle difference is formed between the first air guide plate and each of the second air guide plates, thus realizing the switching of different states of the same structure under different movements.

[0024] 2. The linkage air guide component and the drive air guide component, or two adjacent linkage air guide components, are separated by an air wall to prevent mutual interference between the air guide components.

[0025] 3. When one blade shaft rotates, it drives the other blade shafts to rotate synchronously through the inner blade connecting rod, thereby adjusting the angle of the air blowing from the left and right of the air outlet.

[0026] 4. The first driving element can drive the main body of the drive shaft to rotate in the first direction, causing the first linkage shaft portion of the drive shaft and the second linkage shaft portion of the adjacent transmission shaft to contact the first side surface so that the first air guide plate and each of the second air guide plates form a first angle difference between each pair; or drive the main body of the drive shaft to rotate in the second direction, causing the first linkage shaft portion of the drive shaft and the second linkage shaft portion of the adjacent transmission shaft to contact the second side surface so that the first air guide plate and each of the second air guide plates form a second angle difference between each pair, thus realizing the same structure switching different states during different movements.

[0027] 5. The second driving element can drive the blade shaft to rotate and drive the remaining blade shafts to rotate synchronously through the inner blade connecting rod, thereby adjusting the left and right blowing angle of the air outlet. Attached Figure Description

[0042] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.

[0043] like Figure 1 , Figure 2 As shown, a blade adjustment mechanism includes: a drive air guide assembly and at least one linkage air guide assembly.

[0044] The drive air guide assembly includes a drive shaft, a first connecting rod 200, and a first air guide plate 300.

[0045] The drive shaft includes a drive shaft body 110 and a linkage disc 120 located at one end of the drive shaft body 110; the outer end face of the linkage disc 120 has a first linkage shaft 121, the axis of the first linkage shaft 121 is not coaxial with the axis of the drive shaft; one end of the first connecting rod 200 is rotatably connected to the first linkage shaft 121, and the other end is rotatably connected to the first air guide plate 300; the rotation of the drive shaft can drive the first air guide plate 300 to rotate through the first connecting rod 200.

[0046] The linkage air guide assembly includes a drive shaft, a second connecting rod 500, and a second air guide plate 600.

[0047] The transmission shaft and the drive shaft are coaxially arranged. The transmission shaft includes a transmission shaft body 410 and a main linkage disc 420 and a driven linkage disc 430 located at both ends of the transmission shaft body 410.

[0048] The outer end face of the main linkage disc 420 has an outwardly extending second linkage shaft 421, the axis of which is not coaxial with the axis of the transmission shaft; the outer end face of the linkage disc 430 has an inwardly extending linkage groove 431, the linkage groove 431 having a first side surface 432 and a second side surface 433 that can be linked with the first linkage shaft 121 of the adjacent drive shaft or the second linkage shaft 421 of the adjacent transmission shaft.

[0049] One end of the second connecting rod 500 is rotatably connected to the second linkage shaft 421, and the other end is rotatably connected to the second air guide plate 600; the rotation of the transmission shaft can drive the second air guide plate 600 to rotate through the second connecting rod 500.

[0050] When the drive shaft rotates in the first direction, a first angle difference is formed between each pair of the first air guide plate 300 and each pair of the second air guide plates 600; when the drive shaft rotates in the second direction, a second angle difference is formed between each pair of the first air guide plate 300 and each pair of the second air guide plates 600; wherein, the first direction and the second direction are opposite, and the first angle difference and the second angle difference are different.

[0051] In this embodiment, by rotating the drive shaft along the first direction, the first linkage shaft portion 121 of the drive shaft and the second linkage shaft portion 421 of the adjacent transmission shaft come into contact with the first side surface 432, so that a first angle difference is formed between the first air guide plate 300 and each of the second air guide plates 600. Alternatively, by rotating the drive shaft along the second direction, the first linkage shaft portion 121 of the drive shaft and the second linkage shaft portion 421 of the adjacent transmission shaft come into contact with the second side surface 433, so that a second angle difference is formed between the first air guide plate 300 and each of the second air guide plates 600. This allows the same structure to switch between different states during different movements.

[0052] Preferably, the second air guide plate 600 and the first air guide plate 300 are coaxially arranged; when the drive shaft rotates in the first direction, the axis of the second linkage shaft part 421 and the axis of the first linkage shaft part 121 are coaxial.

[0053] In this embodiment, the second air guide plate 600 and the first air guide plate 300 are coaxially arranged. Therefore, the drive shaft rotates in the first direction, causing the first linkage shaft portion 121 of the drive shaft and the second linkage shaft portion 421 of the adjacent transmission shaft to contact the first side surface 432 so that the first angle difference formed between the first air guide plate 300 and each of the second air guide plates 600 is zero.

[0054] Preferably, the included angle between the first side 432 and the second side 433 is 90°.

[0055] like Figures 1-8 As shown, an air outlet assembly includes a blade adjustment mechanism and a housing assembly. The housing assembly is provided with a first air duct 711 and a second air duct 712. There are two second air ducts 712, and both second air ducts 712 are connected to the first air duct 711. The linkage air guide component and the drive air guide component are both located at the connection between the second air duct 712 and the first air duct 711.

[0056] Specifically, the first air duct 711 is provided with an air wall 713, and the linkage air guide component and the drive air guide component or two adjacent linkage air guide components are separated by the air wall 713.

[0057] In this embodiment, the linkage air guide component and the drive air guide component, or two adjacent linkage air guide components, are separated by an air wall 713 to prevent mutual interference between the air guide components.

[0058] Specifically, the housing assembly includes an outer shell 710 and an inner shell 720. The inner shell 720 is located inside the outer shell 710. The first air duct 711 and the second air duct 712 are both located inside the outer shell 710. The two second air ducts 712 are separated by the inner shell 720. The inner shell 720 is located between two inner blades 820. The air guide shaft, the crank shaft, and the air guide shaft are rotatably connected to the inner shell 720.

[0059] like Figures 1-8 As shown, based on the above-described embodiments, it also includes an inner blade 820 assembly and an inner blade 820 connecting rod.

[0060] The inner blade 820 assembly includes a blade shaft 810, inner blades 820, and a blade linkage part 830. The blade shaft 810 is connected to the housing assembly and can rotate around its own axis. The axis of the blade shaft 810 is perpendicular to the axis of the air guide plate shaft. There are two inner blades 820. Both inner blades 820 are connected to the blade shaft 810 and are located in two second air ducts 712 respectively. One end of the blade linkage part 830 is connected to the inner blade 820 or the blade shaft 810, and the other end of the blade linkage part 830 is rotatably connected to the inner blade 820 linkage rod.

[0061] When one blade shaft 810 rotates, it drives the other blade shafts 810 to rotate synchronously through the inner blade 820 connecting rod.

[0062] In this embodiment, when one blade shaft 810 rotates, it drives the other blade shafts 810 to rotate synchronously through the inner blade 820 connecting rod, thereby adjusting the left and right blowing angle of the air outlet.

[0063] like Figures 1-8 As shown, based on the above embodiment, it also includes a first driving element 910, which is connected to the housing assembly. The drive shaft body 110 is connected to the drive shaft of the first driving element 910, and the first driving element 910 can drive the input handle to rotate.

[0064] Specifically, the first driving element 910 is a motor.

[0065] In this embodiment, the first driving element 910 can drive the drive shaft body 110 to rotate in a first direction, causing the first linkage shaft portion 121 of the drive shaft and the second linkage shaft portion 421 of the adjacent transmission shaft to contact the first side surface 432 so that a first angle difference is formed between the first air guide plate 300 and each of the second air guide plates 600. Alternatively, the drive shaft body 110 can be driven to rotate in a second direction, causing the first linkage shaft portion 121 of the drive shaft body 110 and the second linkage shaft portion 421 of the adjacent transmission shaft to contact the second side surface 433 so that a second angle difference is formed between the first air guide plate 300 and each of the second air guide plates 600. This achieves the switching of different states of the same structure under different movements.

[0066] like Figures 1-8 As shown, based on the above embodiment, a second driving element 920 is also included. The second driving element 920 is connected to the housing assembly, and the blade shaft 810 is connected to the second driving element 920. The second driving element 920 can drive the blade shaft 810 to rotate.

[0067] Specifically, the second drive element 920 is a motor.

[0068] In this embodiment, the second driving element 920 can drive the blade shaft 810 to rotate and drive the other blade shafts 810 to rotate synchronously through the inner blade 820 connecting rod, thereby adjusting the left and right blowing angle of the air outlet.
