Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and more specifically to an automotive air vent. Background Technology
[0002] Car air conditioning vents are an essential component of a car. To meet the temperature requirements of drivers of different heights, body types, and habits, the air conditioning vents rotate around the center of rotation to obtain the preferred airflow speed and temperature.
[0003] Currently, automotive air conditioning vents on the market fall into two categories. One type features purely manual airflow control, where the upper and lower air guide vane assemblies, left and right air guide vane assemblies, and dampers are individually controlled to adjust the airflow direction. This type of solution is technically simple and mature, but its drawback is that it cannot meet the needs of the evolving trends in automotive interior control towards intelligence and electrification.
[0004] The second type is the multi-actuator electric air outlet. The principle is that each electric actuator controls the upper and lower guide vane assemblies, the left and right guide vane assemblies, etc. The drawbacks of this type of air outlet are that the transmission mechanism is complex, the cost is relatively high, and there are problems such as poor operational reliability and large space occupation. Utility Model Content
[0005] To address the shortcomings and defects of existing technologies, a car air vent with good air output effect, compact structure, and stable and reliable operation is provided.
[0006] An automotive air vent includes: an air vent housing, wherein the air vent housing is provided with an air outlet channel, and the air outlet channel is provided with left and right guide vane groups and upper and lower guide vane groups in sequence from the air inlet end to the air outlet end.
[0007] The left and right guide vane groups swing left and right, and cooperate with the upper and lower guide vane groups to swing up and down, so that the air outlet channel outputs airflow in a figure-eight air outlet trajectory.
[0008] The driving mechanism includes a pivot member that can rotate along axis A. The pivot member is provided with a track groove. The left and right guide vane assemblies are connected to the track groove through a linkage member so as to drive the left and right guide vane assemblies to move when the pivot member rotates.
[0009] With the above structure, the automotive air vent of this utility model has the following advantages compared with the prior art: The left and right guide vane assemblies rotate from the initial position of the straight-through air outlet to the first position of the left guide vane's limit angle, then continue to rotate to the right to the second position of the right guide vane's limit angle, and then continue to rotate to the left to the initial position, which constitutes one cycle T1.
[0010] The upper and lower guide vane assembly rotates from the initial position of the straight air outlet downward to the third position of the lower guide vane limit angle, continues to rotate upward to the fourth position of the upper guide vane limit angle, and continues to rotate downward to the initial position, which is one cycle T2, where the ratio of cycle T1 to T2 is 2 to 1.
[0011] The ratio of the left-right rotation period T1 of the left and right guide vane groups to the upper-lower rotation period T2 of the upper-lower guide vane groups is set to 1:2.
[0012] This design allows the airflow to exit in a figure-eight pattern, ensuring that when the air outlet is directed towards the user, it covers all areas of the body, resulting in better airflow and a more comfortable user experience.
[0013] The pivot rotates through the transmission between the track groove and the linkage, thereby causing the left and right guide vane assemblies to perform corresponding actions. It has the characteristics of stable and reliable transmission, and its structure is simpler than that of the gear and linkage transmission mechanism, which helps to reduce space occupation and is suitable for installation in cars with limited space.
[0014] As an improvement of this utility model, the left and right guide vane group includes a number of left and right guide vanes arranged horizontally at intervals, and the number of left and right guide vanes are arranged in a coordinated manner.
[0015] The linkage component is a crank, which is connected to the shaft of one of the left and right guide vanes. The crank is provided with a pin that enters the track groove.
[0016] The trajectory slot has a first trajectory segment, a second trajectory segment, and a third trajectory segment, and the first trajectory segment, the second trajectory segment, and the third trajectory segment are connected in sequence.
[0017] The pivot rotates along a first direction, the first trajectory segment drives the left and right guide vane groups to rotate to the left, the second trajectory segment drives the left and right vane groups to rotate to the right, and the third trajectory segment drives the left and right guide vane groups to rotate to the left.
[0018] As an improvement of this utility model, the trajectory groove further has a fourth trajectory segment, the first end of which is connected to the tail end of the third trajectory segment.
[0019] The pivot rotates along the first direction, and the fourth trajectory segment drives the left and right guide vane groups to continue rotating to the left, so that the left and right guide vane groups are in a position state of closing the air outlet channel.
[0020] As an improvement of this utility model, the pivoting component is a bevel gear;
[0021] The drive mechanism also includes an output gear driven to rotate by an actuator, the output gear having a first output section that meshes with a bevel gear for transmission.
[0022] As an improvement of this utility model, the output gear is provided with a second output part, and the second output part is rotatably arranged coaxially with the first output part;
[0023] The second output section is meshed with a spur gear.
[0024] A transmission pin is provided on one axial end face of the spur gear.
[0025] The upper and lower air guide blade group includes two upper and lower air guide blades, which are arranged vertically at intervals.
[0026] The front ends of the upper and lower guide vanes are hinged to the air outlet housing.
[0027] The transmission pin is connected to a transmission frame, which is provided with a front-to-back extending fitting groove. The fitting groove is located at the tail end of a swing arm, and the front end of the swing arm is hinged to the tail ends of two upper and lower guide vanes respectively.
[0028] The transmission pin enters the mating groove. When the spur gear rotates, the transmission pin travels in the mating groove to drive the transmission frame to rotate up and down, thereby causing the upper and lower guide vanes to swing up and down. Attached Figure Description

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0037] Please see Figure 1-6 As shown, a car air vent includes:
[0038] The air outlet housing 1 is provided with an air outlet channel 1.1. The air outlet channel 1.1 is provided with left and right guide vane groups 2 and upper and lower guide vane groups 3 in sequence from the air inlet end to the air outlet end.
[0039] The left and right guide vane groups 2 swing left and right, and cooperate with the upper and lower guide vane groups 3 to swing up and down, so that the air outlet channel 1.1 outputs airflow in a figure-eight pattern.
[0040] The driving mechanism includes a pivot 4 that can rotate along axis A. The pivot 4 is provided with a track groove 4.1. The left and right guide vane groups 2 are connected to the track groove 4.1 through a linkage 5 so as to drive the left and right guide vane groups 2 to move when the pivot 4 rotates.
[0041] In this process, the left and right guide vane groups 2 rotate from the initial position of the straight-through air outlet to the left to the first position of the left guide vane's limit angle, then continue to rotate to the right to the second position of the right guide vane's limit angle, and then continue to rotate to the left to the initial position, which constitutes one cycle T1.
[0042] The upper and lower guide vane assembly 3 rotates downward from the initial position of the straight air outlet to the third position of the lower guide vane limit angle, continues to rotate upward to the fourth position of the upper guide vane limit angle, and continues to rotate downward to the initial position, which is one cycle T2, where the ratio of cycle T1 to T2 is 2 to 1.
[0043] The ratio of the left-right rotation period T1 of the left and right guide vane group 2 to the up-down rotation period T2 of the upper and lower guide vane group 3 is set to 1:2.
[0044] This design allows the air outlet 1.1 to output airflow in a figure-eight pattern, ensuring that when the air outlet is directed towards the human body, it can cover all areas of the body, resulting in better airflow and a more comfortable user experience.
[0045] The pivot 4 rotates through the transmission between the track groove 4.1 and the linkage 5, thereby causing the left and right guide vane groups 2 to perform corresponding actions. It has the characteristics of stable and reliable transmission, and its structure is simpler than that of the gear and connecting rod transmission mechanism, which helps to reduce space occupation and is suitable for installation in cars with limited space.
[0046] Please see Figure 2-4 As shown, the left and right guide vane group 2 includes several left and right guide vanes arranged horizontally at intervals, and the several left and right guide vanes are arranged in a way that is interconnected.
[0047] The linkage 5 is a crank, which is connected to the shaft of one of the left and right guide vanes. The crank is provided with a pin 5.1 that enters the track groove 4.1.
[0048] The track slot 4.1 has a first track segment 4.11, a second track segment 4.12, and a third track segment 4.13, and the first track segment 4.11, the second track segment 4.12, and the third track segment 4.13 are connected in sequence;
[0049] The pivot 4 rotates in the first direction. The first trajectory segment 4.11 drives the left and right guide vane groups 2 to rotate to the left. The second trajectory segment 4.12 drives the left and right vane groups to rotate to the right. The third trajectory segment 4.13 drives the left and right guide vane groups 2 to rotate to the left.
[0050] When pin 5.1 is at the beginning of the first trajectory segment 4.11, the left and right guide vane assemblies 2 are in a vertical position with straight airflow.
[0051] If the pivot 4 rotates in the first direction, the pin 5.1 travels sequentially in the first trajectory segment 4.11, the second trajectory segment 4.12, and the third trajectory segment 4.13, and the left and right guide vane groups 2 rotate to the left, to the right, and to the left in sequence to guide the airflow.
[0052] Furthermore, at this time, if the pivot 4 rotates in a second direction opposite to the first direction, the left and right guide vane groups 2 will rotate to the right, to the left, and then to the right in sequence.
[0053] After the above improvements, the track groove 4.1 is equipped with multiple track segments, which are sequentially driven by the pin body 5.1, thereby driving the left and right guide vane groups 2 to perform corresponding actions. It has the characteristics of simple structure, compact size and small space occupation.
[0054] The track slot 4.1 also has a fourth track segment 4.14, the beginning of which is connected to the end of the third track segment 4.13.
[0055] The pivot 4 rotates in the first direction, and the fourth trajectory segment 4.14 drives the left and right guide vane groups 2 to continue to rotate to the left, so that the left and right guide vane groups 2 are in the position state of closing the air outlet channel 1.1.
[0056] Traditional figure-eight shaped air outlet devices do not have the function of closing the air outlet channel 1.1. This application solves this problem by setting a fourth track segment 4.14 connected to the end of the third track segment 4.13. When the pin 5.1 is in the fourth track segment 4.14 and the pivot 4 continues to rotate in the first direction, the pin 5.1 can enter the fourth track segment 4.14. The fourth track segment 4.14 drives the left and right guide vane groups 2 to continue to rotate to the left through the pin 5.1 until the air outlet channel 1.1 is closed.
[0057] After the above improvements, this application can enable the left and right guide vane groups 2 to close the air outlet channel 1.1 through the transmission cooperation between the extended fourth trajectory segment 4.14 and the pin body 5.1. It has the characteristics of simple and compact structure, multiple functions and good user experience.
[0058] Please see Figure 1 , Figure 4 As shown, pivot component 4 is a bevel gear;
[0059] The drive mechanism also includes an output gear 6 driven to rotate by the actuator 7, the output gear 6 having a first output part 6.1 that meshes with a bevel gear for transmission.
[0060] A bevel gear is positioned above the air outlet housing 1, and the pin 5.1 extends through the air outlet housing 1 and into the track groove 4.1;
[0061] The actuator 7 and the output gear 6 are both located on the left outer end of the air outlet housing 1. The first output part 6.1 is an umbrella-shaped gear ring that meshes with the bevel gear to drive the bevel gear to rotate in the first direction or in the second direction. The structure is simple and the operation is stable and reliable.
[0062] Please see Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, the output gear 6 is provided with a second output part 6.2, which is rotatably arranged coaxially with the first output part 6.1;
[0063] The second output section 6.2 is meshed with a spur gear 8.
[0064] A transmission pin 8.1 is provided on one end face of the spur gear 8 along the axis;
[0065] The upper and lower air guide vane group 3 includes two upper and lower air guide vanes, which are arranged vertically at intervals.
[0066] The front ends of the upper and lower guide vanes are hinged to the air outlet housing 1.
[0067] The transmission pin 8.1 is connected to a transmission frame 9. The transmission frame 9 is provided with a front-to-back extending mating groove 9.1. The mating groove 9.1 is located at the tail end of a swing arm 10. The front end of the swing arm 10 is hinged to the tail ends of two upper and lower guide vanes respectively.
[0068] The transmission pin 8.1 enters the mating groove 9.1. When the spur gear 8 rotates, the transmission pin 8.1 moves within the mating groove 9.1 to drive the transmission frame 9 to rotate up and down, thereby causing the upper and lower guide vanes to swing up and down.
[0069] The second output part 6.2 meshes with the spur gear 8. The spur gear 8 is linked to the upper and lower guide vane assembly 3 via the transmission frame 9. The second output part 6.2 drives the spur gear 8 to rotate. The transmission pin 8.1 on the spur gear 8 can move back and forth within the transmission groove 9.1, thereby causing the transmission frame 9 to rotate up and down, which in turn drives the upper and lower guide vane assembly 3 to rotate up and down.
[0070] The second output section 6.2 is coaxial with the first output section 6.1. The shaft of the bevel gear and the shaft of the spur gear 8 are arranged perpendicularly. Both are close to the wall of the air outlet housing 1 to make the structure compact and reduce space occupation.
[0071] By driving the output gear 6 through a single actuator 7, the left and right guide vane groups 2 and the upper and lower guide vane groups 3 can be driven synchronously to perform corresponding actions. It has the characteristics of simple structure, convenient control and low cost.
[0072] The pivot component 4, output gear 6, and spur gear 8 are designed with a transmission ratio of 2:2:3 to achieve a figure-eight shaped air sweep.
[0073] The upper and lower guide vane group 3 moves up and down in one cycle, and the left and right guide vane group 2 moves left and right in two cycles. In addition, the air outlet channel 1.1 is closed. The figure-eight blowing trajectory can cover the required blowing points such as the head, chest and abdomen, and can also retain a separate path to close the air outlet channel 1.1 of the left and right guide vane group 2.
[0074] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
