Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to an air outlet with a multi-gear transmission mechanism. Background Art

[0002] The air outlet of the car air conditioner is installed inside the vehicle. The air outlet blows out hot or cold air, thereby adjusting the temperature inside the vehicle and improving the comfort of the driver and passengers.

[0003] In the related art, the air outlet is provided with a horizontal blade group and a vertical blade group for adjusting the air outlet direction at the port near the passenger. The two blade groups are driven by two blade drive motors respectively. The horizontal blade group and the vertical blade group swing in different directions to adjust the wind direction. The two blade drive motors are electrically connected to the buttons on the central control panel respectively. The driver can directly adjust the wind direction through the central control panel during driving, thereby improving driving safety.

[0004] Regarding the above-mentioned related technologies, by setting two groups of blade drive motors with different driving directions, although the dual-motor drive can achieve a more precise driving effect, the dual motors will also occupy a larger installation space inside the car, and the integration of the air outlet system is low, resulting in a reduction in the installation space for other components. Utility Model Content

[0005] In order to improve the problem of low integration of the air outlet system and provide installation space for other components, the present application provides an air outlet with a multi-gear transmission mechanism.

[0006] The air outlet with a multi-gear transmission mechanism provided in the present application adopts the following technical solution:

[0007] An air outlet with a multi-gear transmission mechanism, comprising an outer shell installed at the center console of a car, a vertical blade group arranged in the outer shell, a horizontal blade group connected to the vertical blade group and extending out of the outer shell, a transmission mechanism for linking the vertical blade group with the horizontal blade group, and a damper mechanism arranged in the outer shell on a side away from the horizontal blade group;

[0008] The transmission mechanism includes a blade drive motor for driving the vertical blade group and a vertical transmission shaft arranged on the blade drive motor. The horizontal blade group is provided with a horizontal transmission shaft that is perpendicular to the vertical transmission shaft. The horizontal transmission shaft and the vertical transmission shaft are provided with bevel gear assemblies for transmission at two end positions close to each other.

[0009] By adopting the above technical solution, the bevel gear assembly realizes the linkage of the vertical blade group and the horizontal blade group, and a single blade drive motor can control the blade groups in two directions at the same time. Compared with the traditional dual-motor drive method, it saves the installation space inside the car, improves the integration of the air outlet system, and provides more installation space for other components inside the vehicle. The multi-gear transmission mechanism is reasonably designed, and the components are closely matched to ensure the stability and reliability during the transmission process. Although there is only one motor drive, the motor can still accurately control the swing angle of the two blade groups through the gear transmission system to achieve flexible adjustment of the wind direction. The single motor drive and the control of the dual blade group through gear transmission simplify the internal structure of the air outlet, reduce the number of motors and corresponding control components, and thus reduce production and maintenance costs.

[0010] Further, the vertical blade group includes a vertical blade connecting rod, a vertical blade fixing plate and a plurality of vertical blades arranged at intervals, each of the vertical blades is integrally provided with a first connecting portion on a side close to the vertical blade connecting rod, a plurality of first connecting ring portions are arranged at intervals on the vertical blade connecting rod, and each of the first connecting portions is correspondingly inserted and rotatably connected in the first connecting ring portion;

[0011] The vertical blade fixing plate is fixedly connected to the outer shell, and each vertical blade is integrally provided with an extension shaft on a side away from the first connection portion. Each extension shaft is vertically penetrated and rotatably connected to the vertical blade fixing plate.

[0012] 1. By adopting the above technical solution, the vertical blades are inserted and rotatably connected to the first connecting ring on the vertical blade connecting rod through the first connecting part, so that each vertical blade can rotate independently around its axis while maintaining a firm connection with the connecting rod. The fixed connection between the vertical blade fixing plate and the outer shell provides a solid support foundation for the entire vertical blade group, so that the blades can remain stable during the adjustment process. An extension shaft is set on the vertical blade, and it is vertically inserted and rotatably connected to the vertical blade fixing plate. The vertical blade is swung and adjusted in the vertical direction, thereby realizing the control of the air outlet direction. Combined with the bevel gear assembly in the transmission mechanism, the blade drive motor can drive the vertical blade group to swing smoothly, and then work in conjunction with the horizontal blade group to form a variety of wind direction adjustment effects.

[0013] Furthermore, the vertical blades are an odd number, the vertical blade located at the middle position of the vertical blade connecting rod is defined as a central vertical blade, the first connecting portion on the central vertical blade is a first central connecting portion, and a transmission shaft sleeve is sleeved on the outer wall of the horizontal transmission shaft near one end of the vertical transmission shaft;

[0014] The bevel gear assembly includes a first bevel gear and a second bevel gear meshing with each other, the first bevel gear is located at an adjacent position of the first central connecting portion and below the central vertical blade, the first bevel gear is fixedly connected to the first central connecting portion and the central vertical blade, the center axis of the first bevel gear is staggered with the center axis of the first central connecting portion, and the first bevel gear is coaxially fixedly connected to the vertical transmission shaft;

[0015] The second bevel gear is coaxially and integrally arranged on the transmission sleeve.

[0016] By adopting the above technical solution, the central vertical blade and the first central connecting part thereon are defined as the key transmission point. By setting the first bevel gear at this position and coaxially fixedly connected with the vertical transmission shaft, the accurate transmission of power from the motor to the vertical blade group is ensured. The first bevel gear is fixedly connected to the first central connecting part and the central vertical blade, and its center axis is staggered with the center axis of the first central connecting part, which not only ensures the stability of the transmission, but also avoids the structural interference problem caused by the coaxial arrangement. The second bevel gear is coaxial and integrally arranged on the transmission sleeve. The second bevel gear can rotate with the horizontal transmission shaft and maintain a smooth meshing relationship with the first bevel gear, meeting the precise requirements for wind direction adjustment.

[0017] Furthermore, a clearance gap is reserved between adjacent first connecting ring parts for placing the vertical transmission shaft.

[0018] By adopting the above technical solution, since the central axis of the first bevel gear and the central axis of the first central connecting part are staggered, and the first bevel gear is coaxially fixedly connected to the vertical transmission shaft, the first central connecting part and the vertical transmission shaft are not in the same plane. When the vertical transmission shaft drives the vertical blades to swing, the vertical blade connecting rod moves therewith. When the vertical transmission shaft cannot move, the setting of the clearance ensures that there will be no interference or even collision between the vertical transmission shaft and the connecting ring on the vertical blade connecting rod, thereby avoiding friction and wear between moving parts due to the compact structure and extending the service life of the transmission mechanism.

[0019] Furthermore, the vertical transmission shaft is sleeved on an end away from the first bevel gear and fixedly connected with a motor spline for cooperating with the blade drive motor.

[0020] By adopting the above technical solution, the fixed connection between the motor spline and the drive shaft ensures a stable connection between the two. During long-term use, it can resist the influence of external factors such as vibration and impact, and maintain the stability and reliability of the connection. The motor spline, as a connecting component between the drive shaft and the blade drive motor, can ensure the efficient transmission of power from the motor to the drive shaft. Through precise matching and close contact, it reduces energy loss during the transmission process and improves the efficiency of the transmission system.

[0021] Furthermore, the horizontal blade group includes a horizontal blade connecting rod, a horizontal blade fixing plate and a plurality of horizontal blades arranged at intervals. The number of the horizontal blade fixing plates is two and they are symmetrically arranged at both ends of each of the horizontal blades. The horizontal blade fixing plate and each of the horizontal blades are perpendicular to each other and rotatably connected. A second connecting portion is provided on one side of each of the horizontal blades. Second connecting ring portions are provided at intervals on the horizontal blade connecting rod for each of the second connecting portions to be inserted one by one and rotatably connected.

[0022] By adopting the above technical solution, the number of horizontal blade fixing plates is two and they are symmetrically arranged at both ends of each horizontal blade, providing a stable support for the horizontal blade and ensuring the balance of the blade during the adjustment process. The second connecting ring parts are arranged at intervals on the horizontal blade connecting rod, and are plugged and rotatably connected with the second connecting parts on each horizontal blade in a one-to-one correspondence, so that the horizontal blade can be swung and adjusted in the horizontal direction. Combined with the bevel gear assembly and the vertical transmission shaft in the transmission mechanism, the coordinated work of the horizontal blade and the vertical blade group can be achieved to form a variety of wind direction adjustment effects.

[0023] Furthermore, the horizontal blades are an odd number, and the horizontal blade located at the middle position of the horizontal blade connecting rod is defined as a central horizontal blade, the second connecting portion on the central horizontal blade is a second central connecting portion, the horizontal transmission shaft is integrally arranged on the side of the central horizontal blade close to the vertical transmission shaft, the central axis of the horizontal transmission shaft and the central axis of the second central connecting portion are staggered, the end of the horizontal transmission shaft away from the central horizontal blade connected to the central horizontal blade passes through and protrudes from the horizontal blade fixing plate, and the transmission shaft sleeve is sleeved and fixedly connected to the end position of the horizontal transmission shaft.

[0024] By adopting the above technical solution, the horizontal transmission shaft is integrally arranged on the side of the central horizontal blade close to the vertical transmission shaft, and is staggered with the second central connecting part, thereby enhancing the structural rigidity of the horizontal blade group during the transmission process, ensuring that the horizontal blade can maintain a stable posture when swinging, and reducing deformation that may be caused by vibration or external force. The end of the horizontal transmission shaft away from the central horizontal blade is passed through and protruded from the horizontal blade fixing plate, and the transmission shaft sleeve is sleeved and fixedly connected to the position of the end, so that the horizontal transmission shaft can directly drive the central horizontal blade and the entire horizontal blade group to swing through the horizontal transmission shaft, reducing energy loss during the transmission process and improving transmission efficiency. Since the horizontal transmission shaft is staggered with the central axis of the second central connecting part, this design can produce a certain torque effect during the transmission process, which helps to achieve more precise transmission control.

[0025] Furthermore, the damper mechanism includes a damper plate body, a damper drive motor for driving the damper plate body, and a transmission shaft for connecting the damper drive motor and the damper plate body, the damper drive motor is arranged outside the outer shell, the damper plate body is located inside the outer shell, one end of the transmission shaft is fixedly connected to the damper drive motor, and the end of the transmission shaft away from the damper drive motor passes through the outer shell and is fixedly connected to the damper plate body.

[0026] By adopting the above technical solution, the damper mechanism is set as an independent working unit and separated from the blade group of the air outlet, which effectively reduces the mutual interference and failure rate between the systems, so that each component can focus on its own work task, thereby improving the reliability and stability of the entire air outlet system. The damper plate body can adjust the position and angle of the damper plate body through the precise control of the damper drive motor, so as to accurately control the flow direction and flow rate of the airflow. The damper drive motor is arranged outside the outer shell, and the motor is connected to the damper plate body located in the outer shell through a transmission shaft to realize power transmission. The independent drive system makes the operation of the damper mechanism more stable and reliable. The damper drive motor is located outside the outer shell, and its maintenance and replacement are relatively convenient. When the motor fails or needs to be upgraded, it is convenient to remove it from the outer shell and carry out corresponding processing.

[0027] Furthermore, the damper plate body is perpendicular to the inner side wall of the outer shell and abuts against the inner wall of the outer shell, and an upper limit block and a lower limit block for limiting the swing angle of the damper plate body are integrally provided on the inner wall of the outer shell.

[0028] By adopting the above technical solution, the damper plate is perpendicular to the inner side wall of the outer shell and abuts against the inner wall of the outer shell, and the outer shell provides a reference surface for the swing of the damper plate, so that the damper plate can maintain a stable posture during the swing process. The upper limit block and the lower limit block integrally arranged on the inner wall of the outer shell are used to limit the swing angle of the damper plate, ensuring that the damper plate does not exceed a predetermined range during the swing process, thereby avoiding mechanical interference caused by excessive swing angles.

[0029] Further, the lower part of the damper plate body and the interior of the outer shell together form a first air outlet channel, the first air outlet channel is connected to the horizontal blade group, the upper part of the damper plate body and the interior of the outer shell together form a second air outlet channel, the second air outlet channel is connected to the vertical blade group;

[0030] When the damper plate is located between the upper limit block and the lower limit block, the first air outlet channel and the second air outlet channel are both in an open state;

[0031] When the damper plate abuts against the upper limit block, the first air outlet channel is in an open state;

[0032] When the air door plate abuts against the lower limit block, the second air outlet channel is in an open state.

[0033] By adopting the above technical solution, the lower part of the damper plate body and the inner part of the outer shell together form a first air outlet channel, which is connected to the horizontal blade group; the upper part of the damper plate body forms a second air outlet channel, which is connected to the vertical blade group. The dual channels allow the air outlet to discharge air in two directions simultaneously or separately as needed, thereby improving the flexibility and distribution range of the airflow. By controlling the position of the damper plate body, the opening state of the two air outlet channels can be flexibly adjusted. When the damper plate body is located between the upper limit block and the lower limit block, both air outlet channels are in an open state, realizing the comprehensive distribution of the airflow; when the damper plate body abuts against the upper limit block, the first air outlet channel is opened and the second air outlet channel is closed, and air is discharged in the direction of the horizontal blade group; when the damper plate body abuts against the lower limit block, air is discharged in the direction of the vertical blade group. The position of the damper plate body is precisely limited by the upper limit block and the lower limit block, which can ensure that the opening state of the air outlet channel is stable and reliable, and helps to achieve precise airflow control and avoid waste and interference of airflow.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] 1. The vertical blade group and the horizontal blade group are linked by the bevel gear assembly, so that a single blade drive motor can control the blade groups in two directions at the same time, improving the integration of the air outlet system and reducing the number of required drive motors, thereby saving space inside the vehicle for installing other key components and improving the overall space utilization of the vehicle;

[0036] 2. The various components of the multi-gear transmission mechanism work closely together to ensure stability and reliability during the transmission process. Even if there is only one motor driving, the gear transmission system can accurately control the swing angles of the two blade groups to achieve flexible adjustment of the wind direction, which not only improves the flexibility of the airflow, but also ensures the accuracy of airflow control, meeting the use requirements in different scenarios;

[0037] 3. The damper plate body set in the outer shell makes the air outlet system have a dual-channel function, which can discharge air in two directions simultaneously or separately as needed, improving the distribution range and flexibility of the airflow. The upper limit block and the lower limit block set on the inner wall of the outer shell effectively limit the swing angle of the damper plate body, avoiding mechanical interference and damage caused by excessive swing angle, and improving the durability and service life of the system.

The number of the horizontal blades 33 is an odd number. In this embodiment, the number of the horizontal blades 33 is nine, and the number of the first connecting ring portions 211 is correspondingly nine.

[0058] Reference Figure 5 and Fig. 9 The bevel gear assembly 44 includes a first bevel gear 441 and a second bevel gear 442 . The first bevel gear 441 is coaxially fixedly connected to an end of the vertical transmission shaft 42 away from the motor spline 421 .

[0059] The vertical blade 23 located at the middle position of the vertical blade connecting rod 21 is defined as a central vertical blade 233, and the first connecting portion 231 on the central vertical blade 233 is defined as a first central connecting portion 2331. The first bevel gear 441 is located adjacent to the first central connecting portion 2331 and below the central vertical blade 233. The first bevel gear 441 is fixedly connected to the first central connecting portion 2331 and the central vertical blade 233, and the central axis of the first bevel gear 441 is staggered with the central axis of the first central connecting portion 2331.
