Description

Technical Field

[0001] This utility model relates to the field of exhaust fan technology, and in particular to an energy storage exhaust fan that utilizes the power of a rotating shaft to drive a cover plate. Background Technology

[0002] Energy storage exhaust fans are specifically designed for energy storage systems. They are ventilation devices that forcefully exhaust hot air and harmful gases accumulated in the battery compartment, maintaining suitable temperature and air quality, and ensuring the safe and stable operation of energy storage equipment. As a commonly used air circulation device, an exhaust fan typically consists of a housing, a motor installed inside the housing, and fan blades connected to the motor. The housing has an exhaust vent and an intake vent; the exhaust vent faces inwards towards the battery compartment, and the intake vent faces outwards. When the motor drives the fan blades, it draws air from the battery compartment to the outside, thus achieving ventilation. In practical applications, to prevent external dust from entering the battery compartment through the exhaust vent and intake vent when the exhaust fan is not in use, a flip cover is usually installed at the intake vent. This flip cover is equipped with a powered swing arm system, which opens and closes the cover via the swing arm. When the exhaust fan is not operating, the flip cover can cover the intake vent, effectively preventing dust from entering.

[0003] However, most existing powered swing arm systems use a linear motor hinged to the swing arm, with the linear motion of the motor driving the swing arm to rotate, thus opening and closing the flap. This structure has obvious limitations: firstly, the swing amplitude is large, resulting in the entire powered swing arm system occupying a lot of space, which is not conducive to the miniaturization design and space optimization of the exhaust fan; secondly, the swing speed is slow, making it impossible to achieve a quick opening action. When the exhaust fan needs to be started quickly for ventilation, the flap cannot be opened in time, affecting the efficiency and response speed of the exhaust fan. Therefore, there is an urgent need to propose an improved technical solution to overcome the shortcomings of the existing powered swing arm system and improve the overall performance and user experience of the exhaust fan. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] An energy storage exhaust fan that uses a rotating shaft to drive a cover plate includes a housing with an exhaust port and an exhaust port. Inside the housing, there is a duct that connects to the exhaust port and the exhaust port. A fan is installed inside the duct. Inside the housing, there is also a motor and a transmission mechanism connected to the motor. A rotating shaft is rotatably connected to the housing. One end of the rotating shaft is connected to the transmission mechanism. At least one fixing member is fixedly connected to the rotating shaft. A flip cover is fixedly connected to the rotating shaft through the fixing member. The motor drives the rotating shaft through the transmission mechanism, causing the rotating shaft to drive the flip cover to cover the exhaust port or open the exhaust port.

[0006] Preferably, the cross-section of the rotating shaft is a polygonal structure, and both ends of the rotating shaft have cylindrical ends. The rotating shaft is rotatably connected to the outer shell through the cylindrical ends. The fixing member has a fixing hole that matches the cross-section of the rotating shaft. The fixing member is sleeved on the rotating shaft through the fixing hole. The fixing member is also threaded with a fixing screw that abuts against the rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By adopting a shaft-driven flip cover, compared to the traditional linear motor-hinged swing arm method, the structure of the flip cover driven by the shaft rotation is more compact, greatly reducing the space occupied by the power drive system, which is conducive to the miniaturization design and installation layout of the exhaust fan. At the same time, the rotation of the shaft enables the flip cover to open and close quickly, improving the speed of opening and closing, allowing the exhaust fan to respond more quickly when starting and stopping, effectively improving the efficiency of use. In addition, the power transmission method of the shaft and transmission mechanism is simple and stable, reducing the probability of mechanical failure, enhancing the overall reliability and stability of the exhaust fan operation, and extending the service life of the equipment to a certain extent.

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figure 1-5In this embodiment of the present invention, an energy storage exhaust fan that uses a rotating shaft to drive a cover plate includes a housing 10, on which an exhaust port 11 and an exhaust port 12 are provided. Inside the housing 10, a duct 13 is provided that connects to the exhaust port 11 and the exhaust port 12. A fan 14 is provided inside the duct 13. Inside the housing 10, a motor 15 and a transmission mechanism 40 connected to the motor 15 are also provided. A rotating shaft 16 is rotatably connected to the housing 10. One end of the rotating shaft 16 is connected to the transmission mechanism 40. At least one fixing member 20 is fixedly connected to the rotating shaft 16. A flip cover 30 is fixedly connected to the rotating shaft 16 through the fixing member 20. The motor 15 drives the rotating shaft 16 through the transmission mechanism 40, so that the rotating shaft 16 drives the flip cover 30 to cover the exhaust port 12 or open the exhaust port 12.

[0026] In the above technical solution, the motor 15 establishes a power connection with the rotating shaft 16 through the transmission mechanism 40. When the motor 15 is running, it transmits power to the transmission mechanism 40, which drives the rotating shaft 16 to rotate. The fixing part 20 fixedly connected to the rotating shaft 16 rotates accordingly, thereby driving the flip cover 30 to move. When the exhaust fan is not working, the motor 15 drives the rotating shaft 16 to rotate, so that the flip cover 30 rotates to cover the air vent 12 to prevent external dust from entering. When the exhaust fan needs to work, the motor 15 drives the rotating shaft 16 in the reverse direction, and the flip cover 30 rotates to open the air vent 12, so that the fan 14 can draw air through the air vent 12 and the exhaust vent 11 to realize the circulation of air inside and outside the battery compartment.

[0027] Therefore, the exhaust fan adopts a shaft-driven flip cover 30. Compared with the traditional linear motor 15 hinged swing arm method, the structure of the shaft rotating to drive the flip cover 30 is more compact, greatly reducing the space occupied by the power drive system, which is conducive to the miniaturization design and installation layout of the exhaust fan. At the same time, the rotation of the shaft can realize the rapid opening and closing of the flip cover 30, improving the opening and closing speed of the flip cover 30, enabling the exhaust fan to respond more quickly when starting and stopping, effectively improving the efficiency of use. In addition, the power transmission method of the shaft and the transmission mechanism 40 has a simple and stable structure, reducing the probability of mechanical failure, enhancing the overall reliability and stability of the exhaust fan, and extending the service life of the equipment to a certain extent.

[0028] Please see Figure 3-6Based on the above technical solution, it is further proposed that the cross-section of the rotating shaft 16 is a polygonal structure, preferably hexagonal. The rotating shaft 16 has cylindrical ends 161 at both ends, and the rotating shaft 16 is rotatably connected to the outer shell through the cylindrical ends 161. The fixing member 20 has fixing holes 21 that match the cross-section of the rotating shaft 16. The fixing member 20 is sleeved on the rotating shaft 16 through the fixing holes 21. A fixing screw 22, which normally abuts against the rotating shaft 16, is also threaded onto the fixing member 20. The fixing member 20 is secured by the tight fit between the fixing screw 22 and the rotating shaft 16. The fixed part 20 is fixed on the pivot 16; the polygonal cross section can effectively prevent the fixed part 20 from rotating circumferentially on the pivot 16, ensuring the accuracy of the opening and closing action of the flip cover 30. The cylindrical end 161 facilitates a stable rotational connection with the outer shell, improving the stability of the overall structure. The fixed part 20 is fitted through the fixing hole 21 that matches the cross section of the pivot 16 and is secured by the fixing screw 22. This connection method is not only easy to assemble, but also allows for flexible adjustment of the position of the fixed part 20 on the pivot 16 according to actual needs, enhancing the versatility and adjustability of the structure.

[0029] Specifically, the fastener 20 includes a sheet metal body 23, with snap-fit ​​sheet metal 24 bent at both ends of the sheet metal body 23, and a fixing sheet metal 25 bent on one side of the sheet metal body 23. Fixing screws 22 are provided on the sheet metal body 23, and fixing holes 21 are provided on the snap-fit ​​sheet metal 24. The flip cover 30 is fixedly connected to the fixing sheet metal 25. Through the unique sheet metal bending design of the fastener 20, the snap-fit ​​sheet metal 24 at both ends fits tightly with the pivot 16, and the fixing sheet metal 25 on one side is used to connect the flip cover 30. The reasonable structural layout reduces its own weight and material costs while ensuring connection strength. Furthermore, the structural strength of the sheet metal makes the connection between the flip cover 30 and the pivot 16 more stable and reliable, further improving the stability and durability of the exhaust fan during the opening and closing of the flip cover 30.

[0030] Please see Figure 1-2 Based on the above technical solution, it is further proposed that a groove 17 matching the flip cover 30 is provided inward at the front end of the housing 10, the exhaust port 12 is opened in the groove 17, and the rotating shaft 16 is rotatably connected to the inner wall of the groove 17. One end of the rotating shaft 16 extends into the housing 10 along the inside of the groove 17 to be connected to the transmission mechanism 40. The setting of the groove 17 allows the flip cover 30 and the housing 10 to be better connected, and can improve the sealing between the flip cover 30 and the housing 10 when closed, making the closing of the flip cover 30 more secure and reliable. In addition, by using this setting, the rotating shaft 16 can be cleverly rotatably connected to the inner wall of the groove 17, so that the surface of the housing 10 is flat and there is no protruding structure, which improves the overall aesthetic appeal.

[0031] Please see Figure 4-5Based on the above technical solution, a further proposed transmission mechanism 40 includes a turbine rod 41 fixedly connected to the shaft of the motor 15 and a gear 42 fixedly connected to the end of the rotating shaft 16. The turbine rod 41 and the gear 42 mesh with each other. By using the cooperation of the turbine rod 41 and the gear 42 as the transmission mechanism 40, the turbine rod 41 is driven to rotate by the motor 15, and the rotation of the gear 42 is driven by the helical guidance of the thread. It can generate high torque, which can drive the rotating shaft 16 and thus drive the flap to stably perform the flip-top operation 30, improving the overall strength. At the same time, this structure of turbine rod 41 and gear 42 will not produce large-scale movements, which can improve the compactness of the overall layout, thereby making the overall size of the exhaust fan smaller to a certain extent.

[0032] Please see Figure 4-5 Based on the above technical solution, it is further proposed that two triggers 18 are also provided inside the housing 10, and cams 162 corresponding to the two triggers 18 are fixedly connected to the rotating shaft 16. The two triggers 18 are used to control the rotation stroke of the motor 15. Through the cooperation of the cams 162 and the triggers 18, the rotation angle of the motor 15 can be precisely controlled, thereby accurately controlling the opening and closing position of the flip cover 30, avoiding damage to the exhaust fan structure caused by excessive opening and closing of the flip cover 30, and ensuring the safety of equipment operation. At the same time, this precise stroke control makes the movement of the flip cover 30 more stable during the opening and closing process, effectively reducing the sealing problem caused by incomplete opening and closing, and preventing dust from entering the battery compartment. In addition, the control of the motor 15 stroke by the triggers 18 can also prevent the motor 15 from running idle for a long time or running excessively, reducing the wear of the motor 15, extending the service life of the motor 15, improving the overall reliability and stability of the exhaust fan operation, and optimizing the user experience.

[0033] Please see Figure 1-2 Based on the above technical solution, it is further proposed that a sensor 19 is also installed on the housing 10. The motor 15 and the fan 14 are triggered and driven by the sensor 19, realizing the intelligent operation of the exhaust fan. Taking the smoke sensor 19 and temperature sensor 19 as examples, when the smoke concentration or temperature in the environment reaches the set threshold, the sensor 19 can quickly sense and trigger the motor 15 and the fan 14 to start, without manual operation. It can respond to environmental changes in a timely manner, effectively improving air purification or ventilation efficiency. It also avoids the ineffective operation of the exhaust fan. When the environmental indicators do not meet the triggering conditions, the exhaust fan is in standby mode, which greatly reduces energy consumption and conforms to the concept of energy conservation and environmental protection. In addition, this automated triggering mechanism can also start the exhaust fan in time at the initial stage of potential danger, such as when smoke is generated by fire, to help remove harmful gases and provide protection for the safety of the environment inside the battery compartment, significantly enhancing the practicality and safety of the exhaust fan.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
