Description

Technical Field

[0001] This invention relates to the field of electrical technology, specifically to a sway damper, a vertical electrical appliance, and its working method. Background Technology

[0002] For aesthetic reasons, simplicity, and space-saving design, tower fans are generally designed to be slim and elongated. However, even minor bumps during daily use can cause them to wobble, resulting in a poor user experience. Excessive wobbling can also increase stress on the connection between the fan body and the chassis, potentially leading to product damage. If a tower fan collapses while operating, it can cause a safety hazard. Other slim, upright electrical appliances similar to tower fans also suffer from the aforementioned wobbling problem. Summary of the Invention

[0003] The primary objective of this invention is to provide a sway damper that can be installed on vertical electrical appliances to effectively cope with swaying situations.

[0004] The second objective of this invention is to provide a vertical electrical appliance that can withstand shaking, prevent excessive shaking of long, vertical electrical appliances, improve the stability of such products, enhance product quality, and improve product safety.

[0005] The third objective of this invention is to provide a method for operating a vertical electrical appliance to cope with body swaying.

[0006] The sway damper provided by the first objective of the present invention includes a counterweight located at the center of the sway damper; at least three telescopic mechanisms located on the outer periphery of the counterweight, each telescopic mechanism including a first end and a second end with variable distance, the first end being rotatably connected to the counterweight, and the second end being provided with a rotatable connection structure.

[0007] As can be seen from the above scheme, the sway damper can be installed on the upper part of the vertical appliance body. The second ends of multiple telescopic mechanisms are rotatably connected to the appliance body, thus securing the sway damper. By combining sway data obtained from sensors similar to gyroscopes, the direction of the appliance's sway can be determined. Then, by controlling the multiple telescopic mechanisms, the counterweight is shifted in the opposite direction of the sway, thereby quickly stabilizing the appliance body when it experiences significant swaying. This prevents excessive swaying of tower fans and similar long, narrow appliances, improving the stability of such appliances and enhancing product quality.

[0008] A further option is to install multiple telescopic mechanisms on the same horizontal plane.

[0009] As can be seen from the above, this configuration simplifies the control design of the telescopic mechanism.

[0010] Another further option is to set the telescopic mechanism at an angle to the horizontal plane.

[0011] As can be seen from the above, under this setting, the extension and retraction of multiple telescopic mechanisms can not only cause the counterweight to shift horizontally, but also to shift vertically. For example, the counterweight can shift in the opposite direction and sink at the same time, which can create a better center of gravity adjustment effect.

[0012] A further embodiment is that the counterweight includes a housing with an opening on its outer periphery that connects the interior of the housing to the outer periphery; the first end is located inside the housing, and the telescopic mechanism can swing within the opening.

[0013] As can be seen from the above, under this configuration, even with a large mass and volume, it can be well connected to the telescopic mechanism for rotation.

[0014] A further option is to use a telescopic mechanism that includes a linear motor or a hydraulic rod.

[0015] As can be seen from the above, linear motors have the characteristic of precise control, while hydraulic rods can provide good holding force. These two structures, when used as telescopic mechanisms, can improve the performance of sway dampers in different ways.

[0016] The second objective of this invention is to provide a vertical electrical appliance comprising an upright body, a sensor, and the aforementioned sway damper. The sensor is mounted on the body for detecting sway data of the body. The sway damper is mounted on the upper part of the body. The second ends of multiple telescopic mechanisms are rotatably connected to the body via a rotating connection structure. The telescopic mechanisms can extend and retract according to the sway data.

[0017] As can be seen from the above solution, when the sensor acquires the swaying data of the vertical appliance, the system can determine the direction of the swaying and then control multiple telescopic mechanisms to make the counterweight shift in the opposite direction of the swaying. This allows the vertical appliance to be quickly stabilized when it experiences significant swaying, preventing tower fans and similar long, narrow appliances from swaying excessively, thus improving the stability of such appliances and enhancing product quality.

[0018] A further option is to include a gyroscope as the sensor.

[0019] As can be seen from the above, the use of gyroscopes can not only achieve good detection results, but also reduce costs.

[0020] A further option is to have a vertical electrical unit with a fixed end and a free end, with the sensor positioned closer to the free end than above the sway damper.

[0021] As can be seen from the above, for example, in a tower fan, the top is the free end. When a vertical appliance shakes, the closer to the top of the appliance, the greater the shaking amplitude. Setting the sensor at a higher position can improve the detection sensitivity and accuracy. On the other hand, the higher the position of the sway damper, the more obvious the effect of the sway damper's opposite offset on the change of the center of gravity when the appliance shakes, and the better the timely stabilization effect.

[0022] A further proposed solution is that the fuselage includes an outer shell, with the second end rotatably connected to the outer shell via a rotating connection structure.

[0023] As can be seen from the above, this setting can reduce the difficulty of installing the sway damper.

[0024] Another further option is to use tower fans for the vertical electrical components.

[0025] As can be seen from the above, the swaying problem is particularly noticeable in tower fan products, and this invention can effectively solve the swaying problem of tower fans.

[0026] A further proposed solution is to position the vertical electrical components, including the cross-flow fan blades, sway damper, and sensor, all above the cross-flow fan blades.

[0027] As can be seen above, the vertically arranged cross-flow fan blades occupy most of the fuselage. The area above the cross-flow fan blades allows for the installation of sway dampers and sensors without affecting their normal operation. Moreover, this location is close to the top of the fuselage, which also facilitates the detection effect of the sensors and the adjustment effect of the sway dampers. Thus, the anti-sway function can be achieved without affecting the original structural foundation of the tower fan as much as possible.

[0028] A further option is that the vertical appliance includes an oscillating assembly and a chassis, with the oscillating assembly connected between the chassis and the body, and the oscillating assembly used to achieve relative rotation between the chassis and the body.

[0029] As can be seen from the above, the oscillation assembly includes components such as a stepper motor, a linkage mechanism, and a friction ring. When the motor is turned on, the chassis and the body rotate relative to each other, thereby realizing the left and right oscillation function.

[0030] The third objective of this invention provides a method for operating a vertical electrical appliance, which is applied to the aforementioned vertical electrical appliance. The method includes: if a sensor acquires sway data related to the sway direction of the vertical electrical appliance, the telescopic mechanism is controlled according to the sway data to cause the counterweight to shift in the opposite direction of the sway direction.

[0031] A further approach is to control the telescopic mechanism based on the shaking data, including controlling the telescopic mechanism to shorten if the angle between the setting direction and the opposite direction of the telescopic mechanism is less than 90 degrees; and controlling the telescopic mechanism to extend if the angle between the setting direction and the opposite direction of the telescopic mechanism is equal to or greater than 90 degrees.

[0032] As can be seen from the above solution, when the sensor detects the shaking data of the vertical appliance, the system can determine the direction of the shaking and then control the multiple telescopic mechanisms accordingly to make the counterweight shift in the opposite direction of the shaking. This allows the vertical appliance to be stabilized quickly when it shakes significantly, preventing tower fans and similar long, narrow appliances from shaking excessively, thus improving the stability of such appliances and enhancing product quality.

[0044] First embodiment of vertical electrical appliance

[0045] See Figure 1 and Figure 2In this embodiment, the vertical electrical appliance is a tower fan. The bottom of the tower fan is a fixed end, and the top is a free end. The tower fan includes a body 1, a chassis 19, an oscillation assembly 12, a motor 13, a cross-flow fan blade 14, a gyroscope 2, and the sway damper 3 of this invention. The chassis 19 is located at the bottom of the tower fan, and the body 1 stands upright on the chassis 19. The body 1 includes a slender, upright, and cylindrical outer shell 11. The oscillation assembly 12, the motor 13, the cross-flow fan blade 14, the gyroscope 2, and the sway damper 3 are all housed in the outer shell 11. The oscillation assembly 12 includes a stepper motor, a linkage mechanism, and a friction ring, among other components. The oscillation assembly 12 is connected between the chassis 19 and the body 1. The oscillation assembly 12 is used to realize the relative rotation between the chassis 19 and the body 1, thereby realizing the left and right rotation of the entire body 1 and achieving oscillation airflow from the tower fan. Inside the outer casing 11, the motor 13 is positioned above the oscillating assembly 12 but still at the lower part of the body 1. The motor 13 drives the cross-flow fan 14 to rotate. The cross-flow fan 14 is positioned above the motor 13, extending from the lower part to the upper part of the body 1 and occupying most of the space inside the body 1. The sway damper 3 and the gyroscope 2 are both positioned at the upper part of the body 1, above the cross-flow fan 14. The gyroscope 2 and its connected circuit board are located above the sway damper 3, closer to the top of the body 1. In this embodiment, both the sway damper 3 and the gyroscope 2 are connected to the outer casing 11, and the gyroscope 2 is the sensor of this invention.

[0046] See Figure 3 and Figure 4 The sway damper 3 includes a counterweight 30 located at its center and four telescopic mechanisms. In this embodiment, the telescopic mechanisms are linear motors. For example, a pen-type electric linear actuator motor can be used. The four telescopic mechanisms are a first linear motor 31, a second linear motor 32, a third linear motor 33, and a fourth linear motor 34. The four telescopic mechanisms have the same structure and the same connection method with other components. The following description uses the third linear motor 33 as an example. The third linear motor 33 is rod-shaped and has a first end 331 and a second end 332 that are arranged opposite each other in the length direction. The first end 331 is the main body end of the pen-type electric linear actuator motor, and the second end 332 is the push rod end of the pen-type electric linear actuator motor. When the third linear motor 33 operates and moves the push rod, the distance between the first end 331 and the second end 332 changes.

[0047] The counterweight 30 includes a housing 35 and a stop 36 that fit together vertically, forming an interior 300 between the housing 35 and the stop 36. An opening 301 is provided on the outer periphery of the housing 35, connecting the interior of the housing 35 to its outer periphery. The first end 331 of the third linear motor 33 and the first ends of the other three linear motors are all located within the interior 300 and hinged to the housing 35 via a short shaft 351. The four linear motors can swing within the opening 301. (Further details omitted) Figure 5With the counterweight 30 as the center, four linear motors are evenly distributed around the outer periphery of the counterweight 30. In the initial state, the four linear motors are arranged in a cross shape, that is, the angle between the setting directions of any two adjacent linear motors is 90 degrees. The setting direction of the telescopic mechanism refers to the straight line direction from the first end to the second end. In addition, the second end 332 is provided with a rotatable connection structure 3321. In this embodiment, the four linear motors are set on the same horizontal plane. The second end 332 is rotatably connected to the inner side of the outer shell 11 through the rotatable connection structure 3321. Similarly, the second ends of the first linear motor, the second linear motor, and the fourth linear motor are also rotatably connected to the inner side of the outer shell 11 through their rotatable connection structures.

[0048] Combination Figures 6 to 9 Since multiple telescopic mechanisms can be controlled to extend and retract, and the first and second ends with variable spacing are rotatably connected to the counterweight 30 and the body 1 respectively, under this setting, by controlling the four telescopic mechanisms to extend or shorten to different degrees through the program, the counterweight 30 can be shifted in different directions.

[0049] For example, suppose the first linear motor 31 faces backward, the third linear motor 33 faces forward, the second linear motor 32 faces left, and the fourth linear motor 34 faces right. Figure 6 As shown, when the second linear motor 32 is controlled to shorten the first length, the fourth motor 34 is controlled to extend the first length, and the first linear motor 31 and the third linear motor 33 are controlled to extend the second length (the second length is less than the first length), the counterweight 30 can be shifted to the left.

[0050] like Figure 7 As shown, when the third linear motor 33 is controlled to shorten the first length, the first motor 31 is controlled to extend the first length, and the second linear motor 32 and the fourth linear motor 34 are controlled to extend the second length (the second length is less than the first length), the counterweight 30 can be shifted forward.

[0051] like Figure 8 As shown, when the second linear motor 32 is extended to the first length, the fourth motor 34 is shortened to the first length, and the first linear motor 31 and the third linear motor 33 are extended to the second length (the second length is less than the first length), the counterweight 30 can be shifted to the right.

[0052] like Figure 9 As shown, when the third linear motor 33 is extended to the first length, the first motor 31 is shortened to the first length, and the second linear motor 32 and the fourth linear motor 34 are extended to the second length (the second length is less than the first length), the counterweight 30 can be shifted backward.

[0053] Example of working method of vertical electrical appliance

[0054] The operating method of the vertical electrical appliance of the present invention is applied to the vertical electrical appliance of the present invention, which is equipped with a sway damper and a sensor.

[0055] The working methods of vertical electrical appliances include:

[0056] First, a sway detection step is performed. Specifically, the system uses real-time data acquired by the gyroscope 2 to determine if there is acceleration in the upper part of the fuselage 1. If so, it indicates that the fuselage 1 is currently swaying or tilting. At this point, the system can determine the direction and magnitude of the tilt by using the data from the gyroscope 2. Based on this sway data, the system controls the telescopic mechanism to shift the counterweight 30 in the opposite direction of the tilt. See also... Figure 10 and Figure 11 When the fuselage 1 wobbles to the right, the counterweight 30 shifts to the left; when the fuselage 1 wobbles to the left, the counterweight 30 shifts to the right. If the real-time detection data obtained by the gyroscope 2 determines that the upper part of the fuselage 1 has no acceleration, then the counterweight 30 is controlled to maintain its current position, or the counterweight 30 is controlled to return to its original position. Figure 5 The initial position shown is centered.

[0057] Furthermore, in the step of controlling the telescopic mechanism based on sway data, if the angle between the setting direction and the opposite direction of the telescopic mechanism is less than 90 degrees, the telescopic mechanism is controlled to shorten; if the angle between the setting direction and the opposite direction of the telescopic mechanism is equal to or greater than 90 degrees, the telescopic mechanism is controlled to extend. See also Figure 6 and Figure 10 When the counterweight 30 needs to shift to the left, that is, the opposite direction is to the left, except for the second linear motor 32 which is set to the left, which shortens, the other three linear motors that are set to the front, back and right all extend.

[0058] Under this method, when the tower fan experiences significant swaying, the counterweight 30 can be reversed to quickly adjust the center of gravity, rapidly stabilizing the unit and preventing excessive swaying of the tower fan and similar long, narrow appliances, thus improving the stability and product quality. Furthermore, with multiple telescopic mechanisms, each independently controlled, the counterweight 30 can be reversed regardless of the direction the tower fan sways. Moreover, the sway damper of this invention is an active damper, unlike the passive dampers using elastic or pendulum mechanisms applied in high-rise building seismic applications. Because the active sway damper of this invention can generate a large center of gravity shift in a short time, it has lower weight requirements for the counterweight, better meeting the practical needs of lightweight home appliances.

[0059] Second embodiment of vertical electrical appliance

[0060] See Figure 12In the sway damper 4 of this embodiment, the telescopic mechanism 41 is inclined to the horizontal plane. Specifically, the telescopic mechanism 41 extends inclined downward from the first end to the second end. With this configuration, after the multiple telescopic mechanisms 41 extend and retract, the counterweight 40 can not only be offset horizontally, but also offset vertically. The counterweight 40 offsets in the opposite direction and sinks at the same time, which can achieve a better center of gravity adjustment effect.

[0061] Third embodiment of vertical electrical appliance

[0062] See Figure 13 In the sway damper 5 of this embodiment, there are 3 telescopic mechanisms 51. The three telescopic mechanisms 51 are evenly distributed on the outer periphery of the counterweight 50, and the angle between the setting directions of any two adjacent telescopic mechanisms 51 is 120 degrees.

[0063] Fourth embodiment of vertical electrical appliance

[0064] See Figure 14 In this embodiment, the sway damper 62 is disposed above the gyroscope 61.

[0065] In other embodiments, a hydraulic rod is used as the telescopic mechanism.

[0066] In other embodiments, the standing appliance is a standing air conditioner or a stereo system.

[0067] In other embodiments, the vertical appliance is a suspended inverted appliance, in which case the top of the appliance is a fixed end and the bottom is a free end.

[0068] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
