Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, and in particular to an automotive air conditioning vent with a labyrinth lock structure. Background Technology

[0002] Currently, cars are generally equipped with air conditioning vents for adjusting the angle and volume of airflow. These vents are typically opened or closed by using a lever to move the blades.

[0003] Traditional car air conditioning vents are usually located above the dashboard or center console, and sometimes behind the seats or on the roof. The air conditioning vents are simply designed with blades that guide the direction of the airflow. Drivers and passengers need to push a lever continuously to adjust the tilt of the blades to adjust the direction and force of the airflow to suit the needs of the passengers.

[0004] Regarding the aforementioned technologies, after the driver or passenger opens the air conditioning vent, the position of the blades inside the vent changes compared to when it is closed. Further adjustment of the control lever is still required to regulate the blades, thereby achieving the airflow direction and volume before the vent is closed. This adjustment speed is slow and does not improve the ease of use and user experience of the air conditioning vent. Utility Model Content

[0005] To improve the ease of use of air conditioning vents, this application provides an automotive air conditioning vent with a labyrinth lock structure.

[0006] This application provides an automotive air conditioning vent with a labyrinth lock structure, employing the following technical solution: A car air conditioning vent with a maze lock structure includes a housing, blades, and a lever. An air inlet is located at the bottom of the housing, and an air outlet for accommodating the lever is located at the top. The blades are located inside the housing and arranged along its length. A baffle adapted to the size of the air inlet is rotatably connected to the side of the housing near the air inlet. A lock body is located on one side of the housing along its width, with a button on the lock body. A linkage is located at the lower end of the lock body, connected to the end of the baffle near the lock body. When the button is pressed, the button moves the lock body towards or away from the air inlet. The lock body, through the linkage, causes the baffle to rotate smoothly at a preset angle. The housing also has a maze lock for positioning the button.

[0007] By adopting the above technical solution, supported by the housing, the angle and direction of the blades can be changed by adjusting the lever, thereby changing the direction and angle of the air conditioner's air outlet. When the user presses the button, the lock body moves along the direction of the button press. The lock body, through the linkage, drives the baffle to rotate along the axial direction, thus blocking or unblocking the air inlet. After the user presses the button, the labyrinth lock fixes the button, thereby fixing the linkage rod, and finally fixing the baffle. This allows the baffle to continuously block the air inlet or allow air to continuously enter the air inlet, and the air conditioner air can be blown out of the air outlet along the angle of the blades before closing, which helps to improve the convenience of using the air conditioner's air outlet and the user experience.

[0008] Optionally, the lock body includes a lock block, a lock rod, a limiting rod, and an elastic element. The lock block is connected to the button. The limiting rod is located inside the lock block and parallel to the length direction of the lock block. The elastic element is sleeved on the outside of the limiting rod. The lock rod is set parallel to the length direction of the lock block. One end of the lock rod is located inside the lock block, and the other end is connected to the labyrinth lock. One end of the elastic element is connected to the lock block, and the other end is connected to the housing. In its natural state, the elastic element has the tendency to push the lock rod away from the air outlet.

[0009] By adopting the above technical solution, the locking block supports the locking rod and the limiting rod, the limiting rod supports and guides the elastic element, and the elastic element, in its natural state, pushes the locking block to move closer to the air outlet. When the user presses the button, the elastic element provides clearance space for the locking block and the limiting rod, and the locking block drives the locking rod to slide into the labyrinth lock. The labyrinth lock limits and guides the locking rod and positions the locking block through the locking rod. The locking block is fixed to the baffle through the linkage, which helps to improve the stability of the device.

[0010] Optionally, the linkage includes a linkage rod and a connector. The connector is connected to one end of the baffle near the locking block, and the other end is ball-jointed to one end of the linkage rod along its length. The connection point is offset from the rotation center of the baffle. The end of the linkage rod away from the connector is rotatably connected to the lower end of the locking block.

[0011] By adopting the above technical solution, the linkage rod connects the locking block and the connector. The connector is used to connect the baffle and the linkage rod. When the locking block moves, it drives the linkage rod to move along the direction of button pressing. The linkage rod drives the connector to rotate along the axial direction, thereby causing the connector to drive the baffle to rotate at a preset angle.

[0012] Optionally, the maze lock has a maze channel along the direction of button pressing, and the locking rod is inserted in the maze channel. The two ends of the maze channel are respectively set as working position one and working position two. When the button is pressed, the button drives the locking rod to switch between working position one and working position two. When the locking rod is in working position one, the baffle is opened, and when the locking rod is in working position two, the baffle is closed.

[0013] By adopting the above technical solution, the maze channel guides and limits the locking rod, so that the locking rod slides through working position one and working position two to connect with the maze lock, and fixes the pressed button, thereby fixing the baffle, which helps to improve the stability and convenience of the device.

[0014] Optionally, a fixing rod is connected to the side of the lock block away from the air outlet. The fixing rod is parallel to the length direction of the lock body. When the button is pressed, the lock block drives the fixing rod to slide and connect with the housing along its own length direction. A rack is provided on the side of the fixing rod near the air inlet. The rack is arranged along the length direction of the fixing rod. A damping gear is provided on the housing to mesh with the rack. The damping gear is rotatably connected to the housing.

[0015] By adopting the above technical solution, when the user presses the button, the locking block drives the fixing rod to slide and connect with the housing along the sliding direction of the button. The damping gear slows down the movement speed of the fixing rod by meshing with the rack, thereby slowing down the movement speed of the lock body and finally applying resistance to the button press, which helps to improve the comfort and pressing stability of the button.

[0016] Optionally, a fixing block is provided on the side of the baffle near the connector. The fixing block has a through hole along the length of the baffle. Two clamps are provided on the side of the connector near the baffle. The clamps are made of elastic material. The two clamps tend to move away from each other in their natural state. A positioning block is provided at the end of the clamp that passes through the through hole. The positioning block is located on the side of the two clamps that are opposite to each other, and the positioning block abuts against the side of the fixing block away from the connector.

[0017] By adopting the above technical solution, the fixing block guides and limits the clamping plate through the through hole, and the clamping plate achieves relative fixation between the connector and the fixing block through the positioning block. When the clamping plates approach each other, the clamping plate disengages from the through hole, realizing the disassembly of the connector and the fixing block, which helps to improve the convenience of connector disassembly.

[0018] Optionally, the gear is rotatably connected to a circular plate on the side away from the baffle. The outer circumference of the circular plate is provided with several elastic blocks. In its natural state, the elastic blocks tend to move away from the axis of the circular plate. A buffer seat is provided on the side of the housing near the circular plate. The buffer seat has a rectangular hole for accommodating the elastic blocks. The elastic blocks are inserted into the rectangular hole and abut against the inner wall of the rectangular hole on the side away from the center.

[0019] By adopting the above technical solution, the rectangular hole limits and fixes the elastic block, so that the buffer seat supports and fixes the circular plate through the elastic block, and the circular plate supports and fixes the gear, thereby enabling the buffer seat to support and fix the gear. When the elastic block is close to the axis of the circular plate, the elastic block disengages from the rectangular hole, so as to realize the disassembly of the circular plate and the buffer seat, which is beneficial to improving the convenience of disassembling the circular plate.

[0020] Optionally, the baffle is provided with a flexible guard edge along the circumference, and when the baffle is closed, the flexible guard edge fits against the inner wall of the air inlet.

[0021] By adopting the above technical solution, when the baffle is closed, the flexible edge protector cooperates with the inner wall of the air inlet to block the air conditioning air, which helps to improve the sealing effect of the baffle.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Supported by the housing, the angle and direction of the blades can be changed by adjusting the lever, thereby altering the direction and angle of the air conditioner's airflow. When the user presses the button, the lock body moves along the direction of the button press. The lock body, through a linkage, drives the baffle to rotate along the axial direction, thus blocking or unblocking the air inlet. After the user presses the button, the labyrinth lock fixes the button, thereby fixing the linkage rod, and finally fixing the baffle. This allows the baffle to continuously block the air inlet or allow continuous airflow into the air inlet, and the air conditioner's air can be blown out of the air outlet along the blade angle before closing, improving the ease of use and user experience of the air conditioner's air outlet. 2. The locking block supports the locking rod and the limiting rod. The limiting rod supports and guides the elastic element. In its natural state, the elastic element pushes the locking block towards the air outlet. When the user presses the button, the elastic element provides clearance for the locking block and the limiting rod. The locking block drives the locking rod to slide into the labyrinth lock. The labyrinth lock limits and guides the locking rod and positions the locking block through the locking rod. The locking block is fixed to the baffle through the linkage, which helps to improve the stability of the device. 3. The linkage rod connects the locking block and the connector. The connector is used to connect the baffle and the linkage rod. When the locking block moves, it drives the linkage rod to move in the direction of button pressing. The linkage rod drives the connector to rotate in the direction of its own axis, thereby causing the connector to drive the baffle to rotate in a preset angle. Attached Figure Description

Detailed Implementation

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses an automotive air conditioning vent with a maze lock structure. Example

[0032] Reference Figure 1 and Figure 2 An automotive air conditioning vent 14 with a maze lock 3 structure includes a housing 1. The housing 1 has an air inlet 13 on one vertical side and an air outlet 14 on the other side. Multiple blades 11 are mounted on the side of the housing 1 near the air outlet 14, arranged along the length of the housing 1. A lever 12 for adjusting the angle and direction of the blades 11 is mounted on the inner wall of the air outlet 14. The housing 1 supports the blades 11 and the lever 12, allowing the lever 12 to stably move the blades 11 to adjust the angle of the air conditioning vent.

[0033] Reference Figure 1 and Figure 3 A lock body 2 is installed at one end of the housing 1 along its length. The lock body 2 includes a lock block 21, a lock rod 23, a limiting rod 22, and an elastic element 24. The limiting rod 22 is located inside the lock block 21 and is fixedly connected to the lock block 21. The lock block 21 supports and fixes the limiting rod 22 and the lock rod 23. The elastic element 24 is sleeved on the outside of the limiting rod 22 and is slidably connected to the limiting rod 22. The limiting rod 22 supports and guides the elastic element 24. The elastic element 24 can be a spring. One end of the spring is fixedly connected to the lock block 21, and the other end is fixedly connected to the housing 1. In its initial state, the spring tends to push the lock block 21 away from the air inlet 13. A button 25 is installed on the side of the lock block 21 near the air outlet 14. When the user presses the button 25, the spring is compressed and avoids the lock block 21 and the limiting rod 22.

[0034] Reference Figure 3 and Figure 4 The housing 1 is near the air inlet 13 (reference). Figure 2 One side of the ) is rotatably connected to the air inlet 13 (reference) Figure 2 The baffle 5 is sized to fit the size. The lower end of the locking block 21 is provided with a linkage 4. The linkage 4 includes a linkage rod 41 and a connector 42. The connector 42 is engaged with one side of the baffle 5 along the length direction. The linkage rod 41 is vertically rotatably connected to the lower end of the locking block 21. The end of the linkage rod 41 away from the locking block 21 is hinged to the connector 42. The hinge point is offset from the rotation axis of the baffle 5.

[0035] Reference Figure 1 and Figure 4 Supported by the housing 1, the user presses button 25, which moves the lock body 2. The lock body 2, through the linkage rod 41, rotates the connector 42, causing the connector 42 to rotate the baffle 5 at a preset angle. The baffle 5 then rotates with the air inlet 13 (see reference). Figure 2 When the end faces are fitted, the air inlet 13 (reference) Figure 2 When the user presses button 25 again, the lock body 2 rotates the connector 42 via the linkage rod 41, and the connector 42 causes the baffle 5 to flip, contacting the air inlet 13 (see reference). Figure 2 ) blocking.

[0036] Reference Figure 1 and Figure 5 A maze lock 3 is installed at one end of the housing 1 near the locking block 21. The maze lock 3 is located between the locking block 21 and the lever 12. A maze channel 31 is opened on the side of the maze lock 3 near the locking block 21. The end of the locking rod 23 away from the locking block 21 is located in the maze channel 31. A stop block 313 is set inside the groove. The stop block 313 is fixedly connected to the maze lock 3 and is located in the middle of the maze channel 31. The stop block 313 divides the groove into working position one 311 and working position two 312 along the width direction of the maze channel 31. In the initial state, the locking rod 23 is located at the upper end of the maze channel 31. When the user presses the button 25, the button 25 moves the locking block 21 in the pressing direction. The locking block 21 moves the locking rod 23 down to working position one 311, and then up to working position two 312. The maze lock 3 limits and guides the locking rod 23 through working position one 311 and working position two 312.

[0037] Reference Figure 4The inner wall of the maze passage 31 away from the air inlet 13 is set as a slope 1 314. The side of the stop 313 facing the lock rod 23 when it descends is set as a slope 2 315. The side of the stop 313 near the air inlet 13 is provided with a positioning groove 317. The inner wall of the positioning groove 317 near the slope 2 is set as a slope 3 316. The maze passage 31 also includes a fixing groove 318. The fixing groove 318 is located on the side of the maze passage 31 near the air inlet 13. The opening position of the fixing groove 318 is staggered with the opening position of the positioning groove 317. The maze passage 31 is provided with a slope 4 319 that is directly opposite the positioning groove 317.

[0038] Reference Figure 1 and Figure 5 When the user presses button 25, button 25 moves locking block 21 in the pressing direction, locking block 21 moves locking rod 23. As locking rod 23 moves along inclined plane 1 314, it gradually approaches inclined plane 2 315 along working position 1 311. When locking rod 23 contacts inclined plane 2 315, inclined plane 2 315 guides locking rod 23. Locking rod 23 slides along inclined plane 2 315 into fixed groove 318, slides upward along the inner wall of fixed groove 318 and contacts inclined plane 3 316, slides along inclined plane 3 316 into positioning groove 317. At this time, baffle 5 is parallel to the end face of air inlet 13. When the user presses button 25 again, locking rod 23 descends and slides along inclined plane 4 319 into working position 2 312, and moves upward along working position 2 312. Inclined plane 1 314 guides locking rod 23, causing locking rod 23 to slide to the upper end of maze passage 31.

[0039] Reference Figure 3 and Figure 6 A fixing rod 7 is installed at the lower end of the locking block 21. The user presses the button 25 (see reference). Figure 1 When the button 25 is pressed, the lock body 2 moves the fixed rod 7 along the pressing direction of the button 25. The fixed rod 7 is parallel to the limit rod 22. A buffer seat 6 is installed on the side of the housing 1 near the fixed rod 7. A circular plate 61 is installed on the side of the buffer seat 6 near the lock block 21. The circular plate 61 is coaxially rotatably connected to a damping gear 62. A rack 71 that meshes with the damping gear 62 is installed on the fixed rod 7. When the fixed rod 7 moves, it pushes the damping gear 62 to rotate through the rack 71. The damping gear 62 applies resistance to the movement of the fixed rod 7 through the rack 71, which helps to improve the pressing direction of the button 25 (see reference). Figure 1 Stability and comfort of the pressure.

[0040] Reference Figure 1 and Figure 6A circular plate 61 has multiple elastic blocks 611 mounted circumferentially. In their natural state, the elastic blocks 611 tend to move away from each other. A buffer seat 6 has rectangular holes 63 circumferentially opened to accommodate the elastic blocks 611. The elastic blocks 611 are inserted into the rectangular holes 63 and abut against the side of the rectangular hole 63 away from the axis of the buffer seat 6. The buffer seat 6 fixes the elastic blocks 611 through the rectangular holes 63, thereby supporting and fixing the circular plate 61. When the elastic blocks 611 move closer together, they disengage from the rectangular holes 63, allowing for the disassembly of the circular plate 61 and the buffer seat 6, thus improving the ease of disassembly of the circular plate 61.

[0041] Reference Figure 3 and Figure 4 A fixing block 51 is provided on the side of the baffle 5 near the connector 42. The fixing block 51 has a through hole 52 along its own axis. Two clamping plates 421 are installed on the side of the connector 42 near the baffle 5. The clamping plates 421 are made of elastic material. The two clamping plates 421 tend to move away from each other in their natural state. A positioning block 422 is installed on the side of the clamping plates 421 that passes through the through hole 52. The positioning block 422 is located on the side of the clamping plates 421 that is away from each other and abuts against the side of the fixing block 51 that is away from the locking block 21. When the clamping plates 421 move closer to each other, they disengage from the through hole 52 to realize the disassembly of the connector 42 and the baffle 5, which helps to improve the convenience of disassembling the connector 42.

[0042] Reference Figure 4 The baffle 5 is provided with a flexible guard 53 along the circumference. When the baffle 5 is parallel to the end face of the air inlet 13, the flexible guard 53 fits against the inner wall of the air inlet 13, further improving the sealing effect of the baffle 5 on the air inlet 13.

[0043] The implementation principle of an automotive air conditioning vent 14 with a maze lock 3 structure in this application embodiment is as follows: When the user presses the button 25, the button 25 drives the locking block 21 to move along the pressing direction. The locking block 21 drives the connector 42 to rotate through the linkage rod 41. The connector 42 drives the baffle 5 to flip along a preset angle, thereby blocking and opening the air inlet 13. During the movement of the locking block 21, the locking rod 23 slides along the maze channel 31 to fix the button 25 after it is pressed. When the user does not need the air conditioning air, there is no need to adjust the toggle block 12 and the blade 11. Pressing the button 25 can block the air conditioning air. When the button 25 is pressed again, the baffle 5 flips, the air inlet 13 opens, and the air conditioning air is emitted along the angle of the blade 11 before it is closed. The user does not need to adjust the angle of the blade 11 again, which helps to improve the convenience of using the air conditioning vent 14 and the user experience.

[0044] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
