[0002] With the development of the times, people's requirements for elevator riding experience have gradually upgraded from basic transportation functions to comprehensive needs such as balanced temperature inside the car, physical comfort, and clean air. The traditional air conditioning vents in elevator cars are still mainly designed with fixed angles, which is difficult to match this upgraded demand. The fixed air supply direction leads to uneven airflow distribution inside the car, which is prone to local temperature imbalance. The air conditioning outlets used in traditional elevator cars currently employ a snap-on or threaded structure to precisely connect with the air conditioning duct via a duct connection interface to ensure stable air delivery and prevent air leakage. The fixed frame is made of metal and is manufactured in square or rectangular shapes according to the elevator car. It is fixed to the car body with screws to provide support. The air guide grille and blades are the core of air direction determination. After the mold is integrally formed, the angle is fixed, and the airflow is directed into the car through them. While the traditional air conditioning vents used in elevator cars can control the air outlets, they cannot solve the problems of varying airflow demands within the car or uneven temperature distribution. Therefore, an adjustable-angle air conditioning vent for elevator cars is proposed to address these issues. Utility Model Content

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] Reference Figures 1-3This utility model provides an embodiment of an adjustable-angle air conditioning vent for an elevator car, comprising a frame 1. The frame 1 is the basic support structure for the entire vent, serving to fix and install all other components, allowing the entire device to be stably installed on the elevator car. Multiple rotating shafts 2 are rotatably connected to the inner side of the frame 1, allowing each shaft 2 to rotate around its own axis. The multiple rotating shafts 2 are configured to control different blades, thereby achieving multi-angle adjustment. Gears 3 are fixedly connected to the outer side of each rotating shaft 2, meaning that when the rotating shaft 2 rotates, it drives the gears 3 to rotate synchronously. The gears 3 transmit power through meshing with other gears 3, achieving linkage between multiple components and ensuring coordinated adjustment actions. A blade shaft 5 is fixedly connected to the inner side of each gear 3, so that when the gear 3 rotates, the blade shaft 5 rotates accordingly. The blade shaft 5 is the intermediate component connecting the gear 3 and the blades, serving to transmit rotational motion. The rotation of gear 3 drives the movement of the blades. An upper blade 4 is fixedly connected to the outer side of the upper part of the blade shaft 5. After the two are fixedly connected, the rotation of the blade shaft 5 will directly drive the upper blade 4 to rotate. The upper blade 4 is one of the components of the air outlet used to guide the airflow direction. By rotating itself, it can change the direction of the upper air outlet. A lower blade 10 is fixedly connected to the outer side of the lower part of the blade shaft 5. It can guide the air conditioning air from different positions, making the air outlet range wider and meeting the air supply needs of different positions in the elevator. The outer sides of the upper blade 4 and the lower blade 10 are fixedly connected to the inner side of the gear 3, which strengthens the linkage between the blades and the gear 3. It ensures that when the gear 3 rotates, the upper blade 4 and the lower blade 10 can stably follow the rotation without loosening or misalignment, ensuring the accuracy of the adjustment angle. A control component is installed on the outer side of the rotating shaft 2. The function of the control component is to allow the user to easily control the rotation of the rotating shaft 2, which in turn drives a series of related components to move, ultimately realizing the adjustment of the blade angle, allowing the user to change the air outlet direction according to their own needs.

[0011] Reference Figures 3-5Multiple fixing rods 16 are fixedly connected to the inner side of the frame 1. The main function of the fixing rods 16 is to provide fixed support points for other components, enhancing the structural stability of the entire device. The multiple fixing rods 16 are distributed to distribute the force more evenly, making the device more robust. A wind control frame 11 is fixedly connected to the bottom of the fixing rods 16. This frame 1 structure is used to accommodate and guide the movement of other sliding components, providing a track and space for the sliding of the components. A fan-shaped baffle 17 is fixedly connected to the inner side of the wind control frame 11. This baffle blocks and guides the airflow to a certain extent, while also limiting the sliding range of other components to prevent them from sliding excessively and deviating from the track. A sliding shaft 6 is slidably connected to the inner side of the fan-shaped baffle 17, which can... The inner side of the fan-shaped baffle 17 slides along a certain trajectory. The sliding of the sliding shaft 6 is an important action to realize some adjustment functions. By sliding, it changes its own position, thereby driving the movement of related components. A sliding rod 12 is fixedly connected to the outer side of the sliding shaft 6. When the sliding shaft 6 slides inside the fan-shaped baffle 17, it will drive the sliding rod 12 to move synchronously. The sliding rod 12 is an intermediate structure connecting the sliding shaft 6 and other adjustment components, and plays the role of transmitting the sliding action. An adjustment component is installed on the bottom side of the sliding rod 12. The adjustment component is a structure used to further finely adjust the air outlet angle. The movement of the sliding rod 12 drives the adjustment component to work, making the air outlet angle adjustment more flexible and precise, and meeting different air supply needs.

[0012] Reference Figures 1-3The control component includes a locking block 7, a crucial part of the control assembly. It serves a connecting and fixing function, linking other components of the control assembly to the rotating shaft 2 to ensure effective transmission of control actions. The inner side of the locking block 7 is fixedly connected to the outer side of the rotating shaft 2. When the locking block 7 is subjected to external force, it directly drives the rotating shaft 2 to rotate, thus achieving the purpose of controlling the rotating shaft 2 through the locking block 7. A lever 8 is fixedly connected to the bottom side of the locking block 7, a component convenient for user operation. The user can move the locking block 7 by moving the lever 8, which in turn drives the rotating shaft 2 to rotate, achieving adjustment of the blade angle. The operation is simple and convenient. Multiple rotating parts are provided inside the frame 1. The groove 9, whose shape matches the rotating shaft 2, provides space and support for the rotating shaft 2, allowing it to rotate stably within the groove 9. It also restricts the position of the rotating shaft 2, preventing it from shifting. The outer side of the rotating shaft 2 is rotatably connected to the inner side of the rotating groove 9. The sliding shaft 6 is slidably connected to the inner side of the wind control frame 11. The wind control frame 11 provides guidance and restriction for the sliding shaft 6, ensuring it can only slide along the track inside the frame 11, guaranteeing the accuracy and stability of the sliding action. The outer side of the sliding rod 12 is slidably connected to the inner side of the wind control frame 11. The adjustment assembly includes a support column 14, which is a supporting component within the adjustment assembly. The support column 14 serves to connect and support other components, providing a structural foundation for the normal operation of the adjustment assembly. The top side of the support column 14 is fixedly connected to the bottom side of the slide rod 12. When the slide rod 12 slides, it drives the support column 14 to move together. The support column 14 transmits the sliding motion of the slide rod 12 to other components of the adjustment assembly, making it a crucial connecting structure for transmitting motion within the adjustment assembly. An adjustment shaft 15 is rotatably connected to the bottom side of the support column 14, allowing the adjustment shaft 15 to rotate around the bottom side of the support column 14. The rotation of the adjustment shaft 15 is the key action for the adjustment assembly to achieve angle adjustment, changing the angle of related components through its own rotation. An adjustment fan 13 is fixedly connected to the outer side of the adjustment shaft 15. When the adjustment shaft 15 rotates, it drives the adjustment fan 13 to move. The fan blades 13 rotate together, and adjusting the fan blades 13 can further refine the direction of the airflow, allowing the air conditioning air to blow more precisely to specific areas and improve the comfort of the airflow. The bottom side of the support column 14 abuts against the top side of the adjusting fan blades 13, and the top side of the fan-shaped baffle 17 abuts against the bottom side of the fixing rod 16. This abutting method can enhance the installation stability of the fan-shaped baffle 17. The fixing rod 16 provides upward support for the fan-shaped baffle 17, preventing the fan-shaped baffle 17 from loosening or falling during operation. The top side of the sliding rod 12 abuts against the bottom side of the fixing rod 16, which can limit the sliding range of the sliding rod 12 to a certain extent, preventing the sliding rod 12 from sliding excessively. On the other hand, it can also keep the sliding rod 12 stable during the sliding process and reduce shaking.

[0013] Working principle: First, moving the lever 8 will cause the fixedly connected locking block 7 to move synchronously under force. The inner side of the locking block 7 is fixedly connected to the outer side of the rotating shaft 2, so it will directly drive the rotating shaft 2 to rotate stably in the rotating groove 9 inside the frame 1. The rotating groove 9 provides precise rotation space and position restriction for the rotating shaft 2 to avoid deviation. The rotation of the rotating shaft 2 is synchronously transmitted to the fixedly connected gear 3. After the gear 3 rotates, it drives the upper blade 4 and lower blade 10 on both sides of the fixedly connected blade shaft 5 to rotate, completing the basic air outlet angle adjustment and realizing the initial air supply direction control of different areas in the elevator. 6 can slide along the inner track of the fan-shaped baffle 17 inside the wind control frame 11, which is fixedly connected to the frame 1. The fan-shaped baffle 17 not only limits the sliding range of the sliding shaft 6 to prevent it from deviating from the track, but also helps guide the sliding direction. When the sliding shaft 6 slides, it drives the fixedly connected sliding rod 12 to slide synchronously inside the wind control frame 11. The top side of the sliding rod 12 abuts against the bottom side of the fixed rod 16 to avoid excessive sliding and enhance stability. The sliding action of the sliding rod 12 is directly transmitted to the support column 14 fixedly connected to the bottom side. The support column 14 moves synchronously with the sliding rod 12, accurately transmitting the sliding action to the adjustment component, preparing for subsequent fine angle adjustment.

[0014] Finally, after the support column 14 moves into place with the slide bar 12, the adjustment assembly starts to work. The adjustment shaft 15, which is rotatably connected to the bottom of the support column 14, can rotate flexibly around the support column 14. The support column 14 provides stable support for the adjustment shaft 15 and ensures the flexibility of rotation. The rotation of the adjustment shaft 15 drives the fixedly connected adjustment fan blade 13 to rotate synchronously. The bottom of the support column 14 abuts against the top of the adjustment fan blade 13, enhancing the installation stability of the adjustment fan blade 13 to prevent loosening during rotation. Since the rotation angle of the adjustment fan blade 13 can be precisely controlled by the adjustment shaft 15, it can further refine and guide the air conditioning air that has been initially guided by the upper blade 4 and the lower blade 10, allowing the airflow to be blown more accurately to specific areas in the elevator. Ultimately, it achieves fine adjustment of the air outlet angle, meets the personalized needs of different users for air supply comfort, and realizes multi-level air outlet angle adjustment from basic to fine, taking into account both ease of operation and air supply needs in different scenarios in the elevator.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
