The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] With the continuous development of household appliances, fans, as common air circulation devices, are widely used in homes, offices, and industrial settings. Traditional fans generally consist of a bracket assembly and a fan body that can oscillate on the bracket assembly. The fan body oscillates up and down via an electrically driven component (such as a stepper motor). However, the inventors discovered that in actual use, there is a certain gap between the fan body and the bracket assembly. If a user accidentally inserts their fingers into this gap while the fan is running, it can easily cause a pinching accident, posing a significant safety hazard.

[0033] In view of this, please refer to Figures 1 to 5 This application provides a fan 10, which includes a bracket assembly 100, a fan body 200, an electric drive assembly 300, and a sensing assembly 400. Each component is configured with a specific structure and connection method to achieve rapid response and safety protection when a user's finger enters a dangerous area during operation.

[0034] The bracket assembly 100 is an important supporting component of the overall structure of the fan 10. It is usually made of metal or high-strength plastic and has a horn-shaped or arc-shaped structure to support and guide the fan body 200 to swing up and down within a set range. The bracket assembly 100 has an internal installation space to accommodate the related components of the electric drive assembly 300 and the sensing assembly 400.

[0035] The fan body 200 is rotatably mounted on the bracket assembly 100. The fan body 200 includes a housing, fan blades, and a motor that drives the fan blades to rotate. The fan body 200 is connected to the bracket assembly 100 via a pivot or rotating shaft structure, thereby enabling a vertical swinging function relative to the bracket assembly 100. A gap 101 is formed between the fan body 200 and the bracket assembly 100. This gap 101 may become a potential hand-pinching area when the fan 10 is operating normally.

[0036] An electric drive assembly 300 is disposed inside the bracket assembly 100, preferably a stepper motor or other electric actuator with precise control capabilities. The electric drive assembly 300 is connected to the fan body 200 for driving the fan body 200 to oscillate up and down within a set angle range. When the fan 10 is in operation, the electric drive assembly 300 drives the fan body 200 to oscillate periodically to expand the air delivery range.

[0037] A sensing component 400 is disposed on the corner bracket assembly 100 and electrically connected to the electric drive assembly 300. The sensing component 400 is used to detect whether a finger has entered the gap 101. When the sensing component 400 detects a finger entering the gap 101, it controls the electric drive assembly 300 to stop working. Thus, by placing the sensing component 400 in the gap 101 area between the corner bracket assembly 100 and the fan body 200, it is possible to detect in real time whether a finger or other foreign object has entered this area. Upon detecting an abnormal entry, it immediately controls the electric drive assembly 300 to stop working, thereby effectively preventing safety accidents such as finger pinching.

[0038] In this embodiment, the sensing component 400 can be an infrared sensor, a capacitive proximity sensor, or a mechanical pressure sensor, etc., and the appropriate sensing method can be selected according to different application scenarios. For example, an infrared sensor can determine whether an object has entered the gap 101 by emitting and receiving changes in light; while a capacitive sensor can detect the approach of a human body by changes in capacitance.

[0039] In some embodiments, the sensing component 400 includes a sensing circuit board 410 and a sensing line 420, which are electrically connected. The sensing circuit board 410 is disposed inside the bracket assembly 100 and is securely installed to the bracket assembly 100 through a fixing structure. The sensing circuit board 410 is further electrically connected to the main control circuit board of the fan 10, and at the same time establishes a control path with the electric drive component 300 to realize real-time regulation of the motor's operating status.

[0040] The sensing wire 420 is distributed along the arc surface of the corner bracket assembly 100 and is positioned near the dangerous area where the user's hand might be pinched between the fan body 200 and the corner bracket assembly 100. The sensing wire 420 is made of conductive material, and its surface may be bare or covered with a thin layer of insulating material to create a capacitive sensing field. When a user's finger approaches or enters the gap 101 between the fan body 200 and the corner bracket assembly 100, the human body, acting as a conductive medium, alters the electric field distribution around the sensing wire 420, thereby causing a change in capacitance.

[0041] The sensing circuit board 410 continuously monitors the capacitance state of the sensing line 420. Once a capacitance change exceeds a preset threshold, it determines that a finger or other foreign object has entered the pinch area. At this time, the sensing circuit board 410 generates a control signal and sends it to the main control circuit board through the electrical signal transmission path. After receiving the signal, the main control circuit board immediately sends a stop command to the electric drive assembly 300, cutting off the power supply to the motor and stopping the fan body 200 from swinging, thus preventing a pinching accident.

[0042] Furthermore, the induction line 420 is electrically connected to the induction circuit board 410 via a circular terminal. This connection structure is secured by screws passing through the central bracket, the induction circuit board 410, the terminal of the induction line 420, and a nut, ensuring the stability of electrical conduction and the reliability of the mechanical connection. This installation method not only simplifies the assembly process but also enhances the stability of the overall structure.

[0043] In some embodiments, the bracket assembly 100 includes a first bracket housing 110 and a second bracket housing 120, which are assembled together to form an internal receiving space 102. The first bracket housing 110 and the second bracket housing 120 are fixedly connected by snaps, screws or other conventional connection methods to ensure structural stability and ease of disassembly and maintenance.

[0044] The receiving space 102 is used to house the key control components of the fan 10, particularly the sensing circuit board 410 in the sensing assembly 400 and the sensing wire 420 electrically connected to it. The sensing circuit board 410 is disposed inside the receiving space 102 and is stably installed by a fixing structure; the sensing wire 420 is arranged in the arc area of ​​the bracket assembly 100, and part of its extension is also located in the receiving space 102 to ensure reliable electrical connection between it and the sensing circuit board 410.

[0045] Integrating the sensing circuit board 410 and sensing line 420 within the receiving space 102 formed by the first bracket housing 110 and the second bracket housing 120 not only effectively protects the sensing component 400 from external environmental interference, such as dust, moisture, or mechanical impact, but also improves the compactness and aesthetics of the overall structure. Furthermore, this design helps simplify the wiring structure, improves assembly efficiency, and facilitates later maintenance and replacement.

[0046] In some embodiments, the first bracket housing 110 cooperates with the fan body 200 to form an internal space for accommodating the sensing component 400. As an important structural component of the bracket assembly 100, the first bracket housing 110 is connected to the fan body 200 at one end and cooperates with the second bracket housing 120 at the other end, together forming a closed or semi-closed accommodating space 102 for accommodating the sensing circuit board 410 and related electrical control components.

[0047] The sensing line 420 is disposed on the side of the first corner bracket housing 110 opposite to the receiving space 102, i.e., the outer surface facing the external environment. The sensing line 420 is arranged along the arcuate contour of the first corner bracket housing 110, covering the area between the fan body 200 and the corner bracket assembly 100 where a risk of pinching fingers may occur. The sensing line 420 is made of conductive material, and its surface may be exposed or covered with an insulating layer to create a stable capacitive sensing field.

[0048] By arranging the sensor line 420 on the outside of the first bracket housing 110 and placing electronic control components such as the sensor circuit board 410 within the internal housing space 102, this design achieves a rational layout of functional zones. On the one hand, the sensor line 420 can effectively detect whether a user's finger has entered a dangerous area; on the other hand, key electronic components are well protected from external dust, moisture, or mechanical impacts, improving the overall stability and safety of the fan 10's operation.

[0049] Furthermore, this structural design simplifies the assembly process and improves product maintenance convenience. For example, when it is necessary to replace or adjust the sensing component 400, quick maintenance can be achieved by disassembling the first bracket housing 110 or the fan body 200, without having to disassemble the entire fan 10 structure.

[0050] In some embodiments, the first corner frame housing 110 is provided with a receiving groove, which is disposed on the outer surface of the first corner frame housing 110 and communicates with the receiving space 102 formed by the first corner frame housing 110 and the fan body 200. The receiving groove extends along the arcuate contour of the first corner frame housing 110, and its shape and size are adapted to the arrangement requirements of the sensing line 420.

[0051] The sensing wire 420 is embedded in the receiving groove and forms an integrated structural layout with the first corner bracket housing 110. The sensing wire 420 is made of conductive material and can be a metal wire, conductive strip, or other flexible sensing element with good conductivity. The sensing wire 420 is fixed in the receiving groove by an embedded installation method, which not only improves the flatness and aesthetics of the overall structure, but also effectively prevents the sensing wire 420 from shifting or falling off due to external forces.

[0052] Since the receiving slot is connected to the receiving space 102, one end of the sensing wire 420 can be electrically connected to the sensing circuit board 410 located in the receiving space 102 through a channel reserved inside the slot. This connection structure is stable and reliable, easy to assemble and maintain, and reduces the clutter and safety hazards caused by external wiring.

[0053] By embedding the sensing wire 420 within the receiving slot of the first corner bracket housing 110, not only is the sensing component 400 concealed, improving the overall appearance of the fan 10, but the protective performance of the sensing wire 420 is also enhanced, preventing sensor malfunction due to collisions, friction, or other factors during daily use. Furthermore, this structure also helps improve the capacitive coupling efficiency between the sensing wire 420 and the human body, enhancing detection sensitivity and response speed.

[0054] In some embodiments, the extension direction of the sensing line 420 is consistent with the extension direction of the first bracket housing 110. As an important structural component of the fan 10 bracket assembly 100, the first bracket housing 110 is usually in an arc or curved extension shape to adapt to the oscillation trajectory of the fan body 200 and enhance the overall aesthetic design.

[0055] The sensing line 420 is arranged along the extension direction of the first corner frame housing 110, conforming to its outer contour and set on the outer surface of the first corner frame housing 110 or embedded in a receiving groove on its surface. The sensing line 420 is made of a flexible material with good conductivity, such as metal wire, conductive rubber or printed conductive lines, which can naturally bend and extend with the shape of the first corner frame housing 110, ensuring the coordination of the overall layout and the stability of the sensing function.

[0056] By aligning the extension direction of the sensing line 420 with that of the first corner bracket housing 110, the matching degree between the sensing area and the potential pinch area is improved. This allows the sensing line 420 to more comprehensively cover the gap 101 area between the fan body 200 and the corner bracket assembly 100, thereby enhancing the sensitivity and accuracy of the anti-pinch detection. Furthermore, this arrangement simplifies the wiring structure and reduces signal interference or installation difficulties caused by bending or crossing wiring.

[0057] In some embodiments, the sensing assembly 400 further includes a fastener for securely mounting the sensing wire 420 and the sensing circuit board 410 to the second bracket housing 120. The second bracket housing 120, as another structural component of the bracket assembly 100, typically cooperates with the first bracket housing 110 to form an internal space for accommodating the control elements of the fan 10.

[0058] The fastener uses a mechanical fastening method to reliably install the sensing component 400. Its specific structure can be a conventional connecting element such as a screw, nut, clip, or crimp terminal. Through this fastener, a stable electrical connection is established between one end of the sensing line 420 and the sensing circuit board 410, while the sensing circuit board 410 is also firmly mechanically fixed to the second bracket housing 120.

[0059] Specifically, the fastener passes sequentially through the mounting holes on the second bracket housing 120, the through holes on the sensing circuit board 410, and the circular terminal portion of the sensing line 420, and is secured by nuts or other locking mechanisms. This integrated mounting structure not only ensures the stability of the sensing component 400 during the operation of the fan 10, but also effectively prevents poor contact or detachment caused by vibration or external forces.

[0060] Integrating the sensing line 420 and the sensing circuit board 410 onto the second corner bracket housing 120 using a fastener simplifies the overall assembly process and improves production efficiency. Furthermore, this design facilitates later maintenance and replacement operations, allowing users or technicians to inspect or replace the sensing component 400 without disassembling the fan 10 body.

[0061] In some embodiments, the corner bracket assembly 100 extends circumferentially around the fan body 200. This configuration allows the corner bracket assembly 100 to be arranged around a portion or the entire outline of the fan body 200, thereby forming a relatively closed or semi-closed support frame.

[0062] The bracket assembly 100 includes a first bracket housing 110 and a second bracket housing 120, which cooperate to form an internal space for mounting the electric drive assembly 300, the sensing assembly 400, and other control elements. The bracket assembly 100 is rotatably mounted on the base or bracket of the fan 10 via a rotating connection structure, enabling the fan body 200 to swing up and down or left and right within a set angle range.

[0063] Designing the bracket assembly 100 to extend circumferentially around the fan body 200 not only enhances the structural stability between the bracket assembly 100 and the fan body 200, but also expands the support coverage of the bracket assembly 100 on the fan body 200, which helps to improve the overall operational stability and aesthetic harmony of the fan 10.

[0064] Furthermore, the sensing component 400 arranged on this structure can more effectively cover the potential hand-pinch area between the fan body 200 and the corner bracket assembly 100. The sensing line 420 is distributed along the arc-shaped surface of the corner bracket assembly 100, and its extension path is consistent with the circumferential direction of the corner bracket assembly 100, making the sensing area more closely match the actual danger area and improving the comprehensiveness and sensitivity of the anti-pinch detection.

[0065] In some embodiments, the electric drive assembly 300 is disposed within a receiving space 102 formed by the cooperation of a first bracket housing 110 and a second bracket housing 120. This receiving space 102 is located inside the bracket assembly 100 and is typically enclosed by the bracket housing, providing good sealing and structural protection.

[0066] The electric drive assembly 300 includes a stepper motor or other type of electric actuator for driving the fan body 200 to oscillate up and down or left and right relative to the bracket assembly 100. The electric drive assembly 300 is securely connected to the bracket assembly 100 via a fixed bracket or mounting holes, and is electrically connected to the main control circuit board of the fan 10 to receive control signals from the sensing assembly 400.

[0067] By integrating the electric drive assembly 300 into the housing space 102, not only is the spatial layout of the bracket assembly 100 effectively utilized, but protection for critical power components is also achieved. The housing space 102 can prevent external dust, moisture, and foreign objects from entering, reducing the failure rate of the electric drive assembly 300 due to environmental factors and extending its service life.

[0068] Furthermore, this structural form also helps to enhance the overall neatness and industrial design aesthetics of the fan 10. Since the electric drive component 300 is hidden inside the bracket assembly 100, the clutter caused by exposed wiring and mechanical structures is avoided, making the fan 10 more concise and beautiful, while reducing the risk of accidental touch or collision by the user.

[0069] More importantly, the electric drive component 300 and the sensing component 400 share the same housing space 102 or adjacent areas, which facilitates electrical connection and signal transmission between the two and improves system response speed. When the sensing component 400 detects a finger entering the pinch area, it can quickly transmit a signal to the main control circuit, thereby controlling the electric drive component 300 to stop operating, achieving a fast and effective anti-pinch protection function.

[0070] In some embodiments, the electric drive assembly 300 includes a drive motor 310 and a transmission assembly, which work together to achieve precise control of the oscillation motion of the fan body 200. The drive motor 310, as a power source, is fixedly installed in the receiving space 102 inside the bracket assembly 100 and is securely connected through a bracket or mounting holes; the transmission assembly is connected to the output shaft of the drive motor 310 and further cooperates with the rotation shaft of the fan body 200 to transmit the power output by the motor to the fan body 200, thereby driving the fan body 200 to oscillate up and down or left and right relative to the bracket assembly 100.

[0071] The drive motor 310 is preferably a stepper motor or other micro motor with good speed regulation performance and control precision, capable of starting, stopping, reversing, and adjusting angle according to the instructions of the main control circuit. The transmission components include, but are not limited to, gear sets, worm gear mechanisms, or belt drive structures, the specific form of which can be selected according to the overall structural design requirements of the fan 10. The various components of the transmission assembly achieve efficient power transmission through precise cooperation, ensuring smooth operation, low noise, and fast response of the fan body 200.

[0072] By integrating the drive motor 310 and transmission components into the housing space 102 of the bracket assembly 100, not only is the overall space utilization of the fan 10 improved, but the protection performance of the power system is also enhanced. The housing space 102 effectively prevents dust and foreign objects from entering, reduces mechanical wear, extends service life, and also helps to improve the overall appearance and industrial aesthetics of the fan 10.

[0073] Furthermore, the structural design of the electric drive component 300 works well with the sensing component 400. When the sensing component 400 detects a finger or other foreign object entering the pinch area, it immediately sends a signal to the main control circuit. The main control circuit then controls the drive motor 310 to stop operating, and the transmission component stops power output, causing the fan body 200 to stop swinging quickly, thereby achieving a fast and reliable anti-pinch protection function.
