Description

Technical Field

[0001] This utility model relates to a control device, and more particularly to a toggle control device for raising and lowering electric furniture. Background Technology

[0002] In recent years, working hours have generally increased across industries, leading to longer periods of sitting at desks and resulting in insufficient physical activity and physiological decline. In response, electrically adjustable desks have emerged on the market, allowing users to easily switch between sitting and standing positions while working, thus enabling them to exercise while working. Furthermore, in addition to adjustable desks, other electrically adjustable furniture that allows users to easily and freely adjust its height is also becoming increasingly common.

[0003] Generally, electric furniture has multiple control buttons, such as an up button and a down button. When the user presses the up button, the electric furniture raises its height using an internal motor and mechanism. When the user presses the down button, the electric furniture lowers its height using the same internal motor and mechanism. However, this type of electric furniture uses fixed buttons to trigger the motor in a fixed way, therefore it lacks speed adjustment functionality when raising / lowering the height. In other words, existing electric furniture cannot allow users to adjust the raising / lowering speed according to their preferences, lacking flexibility and convenience. Summary of the Invention

[0004] This utility model provides a toggle control device that can control the speed at which electric furniture is raised and lowered according to the direction and stroke of the toggle lever operated by the user, thereby achieving a speed adaptive effect.

[0005] In one embodiment, the toggle control device of this utility model is used to control the height adjustment of an electric furniture, and includes:

[0006] Upper casing;

[0007] The lower shell and the upper shell form a body, and the body has an accommodating space inside;

[0008] A toggle member has a support portion, one end of which has a fixing portion that fixes the toggle member to the body, and the other end has a movable portion, wherein the support portion and the fixing portion are disposed within the accommodating space, and the movable portion is exposed outside the body.

[0009] A Hall sensor is installed on the support portion;

[0010] A first magnetic body is disposed on the upper housing; and

[0011] A second magnetic body is disposed in the lower housing;

[0012] When the toggle is moved upward for a first stroke and the Hall sensor is located at a first upper critical position close to the first magnetic body and far away from the second magnetic body, the Hall sensor generates a first signal under the influence of the magnetic field of the first magnetic body, wherein the first signal corresponds to the upward first stroke.

[0013] When the toggle is moved downwards for the first stroke and the Hall sensor is located at a first lower critical position close to the second magnetic body and far from the first magnetic body, the Hall sensor generates a second signal under the influence of the magnetic field of the second magnetic body, wherein the second signal corresponds to the downward movement of the first stroke.

[0014] Compared to related technologies, the toggle control device of this utility model can control the speed at which the electric furniture is raised and lowered as the user increases the stroke of the toggle, thereby achieving a speed adaptive effect. Attached Figure Description

[0053] This invention discloses a toggle control device suitable for electric furniture. The toggle control device utilizes the change in magnetic field caused by a Hall sensor approaching / moving away from a magnetic body positioned at a specific location to control the motor speed of the electric furniture when adjusting its height, thereby achieving an adaptive speed function during height adjustment. This invention uses a Hall sensor instead of traditional physical buttons, eliminating travel errors in the mechanism's design. Furthermore, by controlling the motor speed of the electric furniture based on the change in magnetic field between the Hall sensor and the magnetic body, this invention eliminates the problem of varying sensor strength within a certain range, and even inconsistencies in the magnetism of the magnetic body, thus being unaffected by parts and assembly processes.

[0054] Please also refer to Figures 1 to 4 ,in Figure 1 This is an exploded view of the first embodiment of the toggle control device of this utility model. Figure 2 This is an exploded view of the second embodiment of the toggle control device of this utility model. Figure 3 This is an embodiment of the toggle control device of this utility model. Figure 4 This is a cross-sectional view of the first embodiment of the toggle control device of this utility model.

[0055] This invention discloses a toggle control device 2 for connection to electric furniture (e.g., an electric height-adjustable desk) and for controlling the speed at which the electric furniture adjusts its height. Specifically, the toggle control device 2 can be fixedly mounted on one side of the electric furniture. In this invention, the user can pull the toggle member 21 on the toggle control device 2 upwards or downwards. When the toggle member 21 is forced upwards, the electric furniture receives a corresponding signal and raises its height at a corresponding speed; when the toggle member 21 is forced downwards, the electric furniture receives a corresponding signal and lowers its height at a corresponding speed. The technical feature of this invention is that, depending on the user's upward / downward movement of the toggle member 21 (i.e., the degree of upward movement and the degree of downward movement), the electric furniture will raise / lower its height at different speeds.

[0056] Specifically, traditional electric furniture mainly uses fixed buttons (such as up and down buttons) to raise and lower the height. However, this type of electric furniture does not have speed adjustment; when the user presses the up or down button, the furniture only adjusts the height at a fixed speed. This invention uses a toggle control device 2 with a Hall sensor to replace the fixed buttons of traditional electric furniture, allowing the user to freely determine the speed at which the electric furniture is raised / lowered based on the travel of the toggle control device 2.

[0057] like Figures 1 to 4As shown, the toggle control device 2 of this invention includes at least a toggle element 21, a Hall sensor 31, an upper housing 22, a lower housing 23, a first magnetic body 41, and a second magnetic body 42. The upper housing 22 and the lower housing 23 are configured to form a body covering the toggle element 21. An accommodating space 20 is formed inside the body to accommodate at least a portion of the toggle element 21. The Hall sensor 31 is disposed on the toggle element 21. When the toggle element 21 is toggled by the user, the Hall sensor 31 moves accordingly within the accommodating space 20 in the direction of the toggle. More specifically, the toggle control device 2 of this invention can be connected to an electric furniture (not shown) to be controlled. When the toggle element 21 is subjected to upward or downward force, only the toggle element 21 moves within the accommodating space 20 of the body, but the body (i.e., the upper housing 22 and the lower housing 23) does not move with the movement of the toggle element 21.

[0058] In one embodiment, the toggle control device 2 also includes a wire 5. The toggle control device 2 can receive power through the wire 5 and can transmit control signals to the controller of the electric furniture (not shown) through the wire 5.

[0059] The actuating member 21 has a fixed portion 213 at one end and a movable portion at the other end. The actuating member 21 is fixed to one side of the body via the fixed portion 213. The movable portion has a handle 211 for user operation. Since one end of the actuating member 21 is fixed to the body via the fixed portion 213, the user can operate the handle 211 at the other end of the actuating member 21 to move the actuating member 21 upwards or downwards. At this time, the actuating member 21 swings upwards or downwards with force relative to the fixed portion 213. In other embodiments, the actuating member 21 can change the fixing direction between the fixed portion 213 and the body, thereby swinging leftwards or rightwards with force relative to the fixed portion 213, and is not limited to the above. For ease of understanding, the following description only uses the example of the user applying force to the handle 211 of the actuating member 21 to move the actuating member 21 upwards or downwards.

[0060] like Figure 1 and Figure 2 As shown, a Hall sensor 31 is disposed on the actuating member 21. A first magnetic body 41 is disposed on the upper housing 22, and the position of the first magnetic body 41 on the upper housing 22 corresponds to the position of the Hall sensor 31 on the actuating member 21. A second magnetic body 42 is disposed on the lower housing 23, and the position of the second magnetic body 42 on the lower housing 23 corresponds to the position of the Hall sensor 31 on the actuating member 21. In one embodiment, when the Hall sensor 31 is in the initial position (i.e., the actuating member 21 is not under force, the Hall sensor 31 is in the position shown in the diagram), the Hall sensor 31 is in the position shown in the diagram. Figure 5At the initial position A shown, the first magnetic body 41, the Hall sensor 31, and the second magnetic body 42 are arranged vertically or nearly vertically.

[0061] In one embodiment, the first magnetic body 41 and the second magnetic body 42 have opposite magnetic properties, and when the Hall sensor 31 is located in the initial position A, the straight-line distance between the first magnetic body 41 and the Hall sensor 31 is equal to the straight-line distance between the second magnetic body 42 and the Hall sensor 31. In one embodiment, the first magnetic body and the second magnetic body are magnets with opposite magnetic properties. For example, the first magnetic body 41 is an N-pole magnet and the second magnetic body 42 is an S-pole magnet, and the straight-line distance between the first magnetic body 41 and the Hall sensor 31 is equal to the straight-line distance between the second magnetic body 42 and the Hall sensor 31. When the actuating member 21 is not under force and the Hall sensor 31 is located in the initial position A, the induced magnetic field of the Hall sensor 31 is zero.

[0062] As mentioned above, when the actuating element 21 is moved upward or downward under force, the main body will remain fixed on the electric furniture and will not move with it. That is to say, the first magnetic body 41 and the second magnetic body 42 will not move either. Therefore, when the actuating element 21 is moved upward under force, the Hall sensor 31 moves upward with the actuating element 21 to approach the first magnetic body 41 on the upper housing 22; when the actuating element 21 is moved downward under force, the Hall sensor 31 moves downward with the actuating element 21 to approach the second magnetic body 42 on the lower housing 23.

[0063] More specifically, when the user pulls the lever 21 upwards, the Hall sensor 31 moves upwards (i.e., towards the upper housing 22) along with the lever 21, causing the straight-line distance between the first magnetic body 41 and the Hall sensor 31 to be shorter than the straight-line distance between the second magnetic body 42 and the Hall sensor 31. At this time, the magnetic field sensed by the Hall sensor 31 undergoes a first change due to the influence of the first magnetic body 41. When the user pulls the lever 21 downwards, the Hall sensor 31 moves downwards (i.e., towards the lower housing 23) along with the lever 21, causing the straight-line distance between the second magnetic body 42 and the Hall sensor 31 to be shorter than the straight-line distance between the first magnetic body 41 and the Hall sensor 31. At this time, the magnetic field sensed by the Hall sensor 31 undergoes a second change due to the influence of the second magnetic body 42.

[0064] In one embodiment, the toggle control device 2 obtains the power required for operation from an external source or from the connected electric furniture, and provides a fixed current to the Hall sensor 31, causing the Hall sensor 31 to operate continuously. As described above, since the first magnetic body 41 and the second magnetic body 42 have opposite magnetisms and are equidistant from the Hall sensor 31, the magnetic field of the Hall sensor 31 is zero when the user does not operate the toggle 21. When the Hall sensor 31 moves upward to approach the first magnetic body 41 or downward to approach the second magnetic body 42 with the toggle 21, the generated magnetic field is affected by the first magnetic body 41 / second magnetic body 42, resulting in a potential difference at the output terminal (not shown) of the Hall sensor 31. In this invention, the potential difference can be used as a signal related to the distance between the Hall sensor 31 and the first magnetic body 41 / second magnetic body 42. Therefore, the toggle control device 2 of this invention uses a Hall sensor 31 to generate a voltage signal of corresponding strength based on the magnetic field changes caused by the first magnetic body 41 and the second magnetic body 42. The toggle control device 2 can directly or indirectly control the connected electric furniture based on this voltage signal. In this way, the toggle control device 2 can control the electric furniture to rise or fall at a corresponding speed based on the user's operation of the toggle member 21.

[0065] In one embodiment, the toggle control device 2 has an elongated toggle member 21, and includes a movable portion (and a grip 211 on the movable portion), a support portion 212, and a fixing portion 213. For example... Figures 1 to 4 As shown, a fixing part 213 is disposed at one end of a supporting part 212, and a movable part is disposed at the other end of a supporting part 212. The fixing part 213 and the supporting part 212 are disposed within the accommodating space 20 inside the main body, while the movable part protrudes outside the accommodating space 20. A grip 211 is disposed on the movable part, meaning the grip 211 is also disposed on one side of the supporting part 212 and protrudes outside the accommodating space 20 inside the main body for user operation. The fixing part 213 is disposed on the side of the supporting part 212 away from the movable part, used to fix the actuating member 21 to the main body.

[0066] The toggle control device 2 further includes a circuit board 3. The circuit board 3 is disposed on the support portion 212 of the toggle member 21. In one embodiment, a Hall sensor 31 is electrically connected to the circuit board 3, which is disposed on the support portion 212 of the toggle member 21. In this embodiment, the toggle control device 2 provides a fixed current to the circuit board 3, which is input to the Hall sensor 31 through the circuit board 3, causing the Hall sensor 31 to operate continuously during the activation of the toggle control device 2. In one embodiment, the toggle control device 2 provides a fixed current to the circuit board 3 via an internal or external power source. In another embodiment, the toggle control device 2 obtains power from the connected electric furniture to provide a fixed current to the circuit board 3.

[0067] In one embodiment, the toggle control device 2 may further include a transmission unit (not shown). The transmission unit is electrically connected to the circuit board 3 and is electrically connected to the Hall sensor 31 via the circuit board 3. In this embodiment, the toggle control device 2 transmits the signal generated by the Hall sensor 31 to the connected electric furniture via the transmission unit in a wired or wireless manner, thereby enabling the processor of the electric furniture to control the speed at which the electric furniture raises / lowers its height based on the magnetic field sensed by the Hall sensor 31 and the generated signal.

[0068] In one embodiment, the toggle control device 2 further includes a reset structure 214 disposed on the support portion 212. Figure 1 In this embodiment, the toggle control device 2 has two reset structures 214, respectively disposed on both sides of the support portion 212. Each reset structure 214 contains a spring (not shown in the figure), and with the support portion 212 as the center, the reset structure 214 has an upward-facing upper protrusion and a downward-facing lower protrusion, wherein the upper protrusion abuts against the inner side of the upper housing 22, and the lower protrusion abuts against the inner side of the lower housing 23. When the toggle member 21 is not under force, the toggle member 21, through the upper and lower protrusions of the reset structures 214, abuts against the upper housing 22 and the lower housing 23 respectively, to support the support portion 212 and stably maintain it in its initial position (e.g., ...). Figure 5 The initial position is shown as A). When the user moves the lever 21 upwards to the first position, the upper protrusion of the reset structure 214 is compressed inwards by the upper housing 22. At this time, the spring inside the reset structure 214 is continuously compressed by the upper protrusion and provides a reaction force to the upper housing 22. When the user finishes operating, the lever 21 returns from the first position to the initial position A through the reaction force provided by the spring of the reset structure 214. Conversely, when the user moves the lever 21 downwards to the second position, the lower protrusion of the reset structure 214 is compressed inwards by the lower housing 23. At this time, the spring inside the reset structure 214 is compressed by the lower protrusion and provides a reaction force to the lower housing 23. When the user finishes operating, the lever 21 returns from the second position to the initial position A through the reaction force provided by the spring of the reset structure 214. When the toggle 21 returns to the initial position A, the controller of the electric furniture can determine from the voltage signal provided by the toggle control device 2 that the user's operation has ended (that is, the magnetic field of the Hall sensor 31 is zero at this time), and control the motor to stop rotating. At this time, the electric furniture stops raising / lowering its height.

[0069] In this invention, the toggle control device 2 further includes an upper trigger switch 321 and a lower trigger switch 322. Figures 1 to 4In this embodiment, the upper trigger switch 321 is electrically connected to one side of the circuit board 3, and the lower trigger switch 322 is electrically connected to the other side of the circuit board 3. More specifically, the upper trigger switch 321 is disposed on the first side of the circuit board 3 facing the upper housing 22. An upper protrusion 221 protrudes from the inner side of the upper housing 22 in the direction facing the circuit board 3. The position of the upper trigger switch 321 on the circuit board 3 corresponds to the position of the upper protrusion 221 on the inner side of the upper housing 22. The lower trigger switch 322 is disposed on the second side of the circuit board 3 facing the lower housing 23. A lower protrusion 231 protrudes from the inner side of the lower housing 23 in the direction facing the circuit board 3. The position of the lower trigger switch 322 on the circuit board 3 corresponds to the position of the lower protrusion 231 on the inner side of the lower housing 23.

[0070] In this invention, when the user pulls the lever 21 upwards to the first stroke, the Hall sensor 31 approaches the first magnetic body 41 on the upper housing 22 and moves away from the second magnetic body 42 on the lower housing 23. At this time, the induced magnetic field of the Hall sensor 31 changes accordingly, outputting a voltage signal with a corresponding signal strength (such as the first signal), and the electric furniture connected to the lever control device 2 will rise in height at a first speed. When the user continues to pull the lever 21 upwards to the second stroke, the upper trigger switch 321 will touch the upper protrusion 221 on the upper housing 22 and be triggered. At this time, the upper trigger switch 321 or the controller (not shown) will generate a corresponding control signal (such as the second signal), causing the electric furniture connected to the lever control device 2 to rise in height at a second speed. When the user pulls the lever 21 downwards to the first stroke, the Hall sensor 31 approaches the second magnetic body 42 on the lower housing 23 and moves away from the first magnetic body 41 on the upper housing 22. At this time, the induced magnetic field of Hall sensor 31 will change accordingly, outputting a voltage signal with a corresponding signal strength (such as the third signal), and the electric furniture connected to the toggle control device 2 will lower its height at the first speed. When the user continues to pull the toggle member 21 down to the second stroke, the lower trigger switch 322 will touch the lower protrusion 231 on the lower housing 23 and be triggered. At this time, the lower trigger switch 322 or the controller (not shown) can generate a corresponding control signal (such as the fourth signal), causing the electric furniture connected to the toggle control device 2 to lower its height at the second speed.

[0071] In one embodiment, the first stroke is shorter than the second stroke, and the first speed is slower than the second speed.

[0072] In one embodiment, when the user moves the lever 21 up or down to the first stroke, the electric furniture connected to the lever control device 2 raises or lowers its height at a medium speed (or half speed). When the user moves the lever 21 up or down to the second stroke (i.e., the upper trigger switch 321 touches the upper protrusion 221 or the lower trigger switch 322 touches the lower protrusion 231), the electric furniture connected to the lever control device 2 raises or lowers its height at full speed.

[0073] In one embodiment, the upper trigger switch 321 and the lower trigger switch 322 are metal domes or snap domes. When the toggle member 21 moves upward to the position where the upper protrusion 221 can press the upper trigger switch 321, the upper trigger switch 321 is turned on, causing the upper trigger switch 321 or the controller of the toggle control device 2 to generate a corresponding control signal. When the toggle member 21 moves downward to the position where the lower protrusion 231 can press the lower trigger switch 322, the lower trigger switch 322 is turned on, causing the lower trigger switch 322 or the controller of the toggle control device 2 to generate a corresponding control signal.

[0074] like Figure 3 As shown, a display panel 210 may also be provided inside the handle 211 of the toggle member 21, and the display panel 210 is electrically connected to the circuit board 3 on the support portion 212. In one embodiment, the display panel 210 displays the current travel of the toggle member 21 (e.g., whether it is pulled up or down, and the distance of the pull). In one embodiment, the display panel 210 displays whether the upper trigger switch 321 and the lower trigger switch 322 are triggered when the toggle member 21 is pulled. In one embodiment, the display panel 210 displays the current height of the electric furniture when the height of the electric furniture is adjusted. In one embodiment, the display panel 210 displays the current speed at which the electric furniture is adjusting its height. However, the above are only some specific embodiments of this utility model. The display panel 210 can display different information at different times according to the user's settings, thereby assisting the user in setting the toggle control device 2 and controlling the electric furniture.

[0075] Please continue reading Figures 5 to 9 These are cross-sectional views of the second to sixth embodiments of the toggle control device of this utility model.

[0076] like Figure 5As shown, when the user does not operate the device, the toggle 21 maintains the Hall sensor 31 in the initial position A through the support of the fixing part 213 and the reset structure 214. As mentioned above, when the Hall sensor 31 is in the initial position A (i.e., the user has not moved the toggle 21), the magnetic field is zero. At this time, the Hall sensor 31 does not generate a signal, or the generated signal has a signal strength corresponding to a zero magnetic field. Therefore, the electric furniture connected to the toggle control device 2 will not be height adjusted.

[0077] like Figure 6 As shown, when the user pulls the lever 21 upwards to the first stroke, the Hall sensor 31 moves upwards to the first upper critical position B1. Figure 6 In this embodiment, when the Hall sensor 31 is at the first upper critical position B1, the straight-line distance between it and the first magnetic body 41 is less than the straight-line distance between it and the second magnetic body 42, and at this time, neither the upper trigger switch 321 nor the lower trigger switch 322 is triggered. When the toggle member 21 moves upward to the first stroke, the Hall sensor 31 generates a voltage signal (such as the first signal) with a corresponding signal strength based on the change in the magnetic field caused by the first magnetic body 41. The signal strength of the first signal corresponds to the first stroke. In this embodiment, the electric furniture connected to the toggle control device 2 controls the motor to rotate at a corresponding speed (e.g., rotating forward at half speed) based on this first signal to increase its height.

[0078] In one embodiment, the first magnetic body 41 is an N-pole magnet and the second magnetic body 42 is an S-pole magnet. When the user pulls the lever 21 upward to the first stroke, the Hall sensor 31 moves closer to the upper first magnetic body 41 and further away from the lower second magnetic body 42 (i.e., located at the first upper critical position B1). At this time, the induced magnetic field of the Hall sensor 31 is affected by the upper N-pole magnet, resulting in a first change, and thus the signal strength of the generated voltage signal also changes accordingly. Therefore, the controller can determine that the user has pulled the lever 21 upward to the first stroke based on the signal strength of the voltage signal of the Hall sensor 31. When the user releases the force, the lever 21 returns to the initial position A through the reaction force of the reset structure 214. At this time, the induced magnetic field of the Hall sensor 31 becomes zero, so the electric furniture stops adjusting its height.

[0079] like Figure 7 As shown, when the user further pulls the lever 21 upwards to the second stroke, the Hall sensor 31 moves upwards to the second upper critical position C1. Specifically, the second stroke is greater than the aforementioned first stroke, meaning that... Figure 7 In this embodiment, the user pulls the lever upwards to a greater degree than in... Figure 6 The extent to which it is pulled upwards in the embodiment.

[0080] When the Hall sensor 31 is in the second upper critical position C1, the straight-line distance between it and the first magnetic body 41 is less than the straight-line distance between it and the second magnetic body 42, and at this time, the upper trigger switch 321 is triggered by the upper protrusion 221 on the inner side of the upper housing 22. When the toggle member 21 moves upward to the second stroke and causes the upper trigger switch 321 to be triggered, the controller of the electric furniture will generate a corresponding control signal (such as a second signal) based on the triggering of the upper trigger switch 321. The second signal corresponds to the second stroke. In this embodiment, the electric furniture controls the motor to rotate at a corresponding speed (e.g., rotate forward at full speed) based on the second signal to increase the height.

[0081] like Figure 8 As shown, when the user pulls the lever 21 downwards to the first stroke, the Hall sensor 31 moves downwards to the first lower critical position B2. Figure 8 In this embodiment, when the Hall sensor 31 is at the first lower critical position B2, the straight-line distance between it and the second magnetic body 42 is less than the straight-line distance between it and the first magnetic body 41, and neither the upper trigger switch 321 nor the lower trigger switch 322 is triggered. When the toggle member 21 moves downward to the first stroke, the Hall sensor 31 generates a voltage signal (such as a third signal) with a corresponding signal strength based on the change in the magnetic field caused by the second magnetic body 42. The signal strength of the third signal corresponds to the first stroke. In this embodiment, the electric furniture connected to the toggle control device 2 controls the motor to rotate at a corresponding speed (e.g., reverse at half speed) based on the third signal to lower the height.

[0082] In one embodiment, the first magnetic body 41 is an N-pole magnet and the second magnetic body 42 is an S-pole magnet. When the user pulls the lever 21 downwards to the first stroke, the Hall sensor 31 moves closer to the lower second magnetic body 42 and away from the upper first magnetic body 41 (i.e., located at the first lower critical position B2). At this time, the induced magnetic field of the Hall sensor 31 is affected by the lower S-pole magnet, resulting in a second change, and thus the signal strength of the generated voltage signal also changes accordingly. Therefore, the controller can determine that the user has pulled the lever 21 downwards to the first stroke based on the signal strength of the voltage signal of the Hall sensor 31. When the user releases the force, the lever 21 returns to the initial position A through the reaction force of the reset structure 214. At this time, the induced magnetic field of the Hall sensor 31 becomes zero, so the electric furniture stops adjusting its height.

[0083] like Figure 9 As shown, when the user further pulls the lever 21 downwards to the second stroke, the Hall sensor 31 moves downwards to the second lower critical position C2. Specifically, the second stroke is greater than the aforementioned first stroke, meaning that... Figure 9 In this embodiment, the user pulls the lever downwards to a greater extent than in... Figure 8The extent to which it is pulled downwards in the embodiment.

[0084] At Figure 9 In this embodiment, when the Hall sensor 31 is at the second lower critical position C2, the straight-line distance between it and the second magnetic body 42 is less than the straight-line distance between it and the first magnetic body 41, and at this time, the lower trigger switch 322 is triggered by the upper protrusion 221 on the inner side of the lower housing 23. When the toggle member 21 moves downward to the second stroke and causes the lower trigger switch 322 to be triggered, the controller of the toggle control device 2 or the controller of the electric furniture will generate a corresponding control signal (such as a fourth signal) based on the triggering of the lower trigger switch 322. The fourth signal corresponds to the second stroke. In this embodiment, the electric furniture controls the motor to rotate at a corresponding speed (e.g., reverse at full speed) based on the fourth signal to lower the height.

[0085] Specifically, when the user wants to slowly raise the height of the electric furniture, they can slightly move the lever 21 upwards (e.g., to the first stroke). At this time, the lever control device 2 will control the electric furniture to rise slowly (e.g., half speed) through the first change in the magnetic field sensed by the Hall sensor 31. When the user wants to quickly raise the height of the electric furniture, they can significantly move the lever 21 upwards (e.g., to the second stroke). At this time, the lever control device 2 will control the electric furniture to rise at high speed (e.g., full speed) through the triggering of the upper trigger switch 321. When the user wants to slowly lower the height of the electric furniture, they can slightly move the lever 21 downwards (e.g., to the first stroke). At this time, the lever control device 2 will control the electric furniture to descend slowly (e.g., half speed) through the second change in the magnetic field sensed by the Hall sensor 31. When the user wants to quickly lower the height of the electric furniture, they can significantly move the lever 21 downwards (e.g., to the second stroke). At this time, the lever control device 2 will control the electric furniture to descend at high speed (e.g., full speed) through the triggering of the lower trigger switch 322.

[0086] In this invention, the Hall sensor 31 continuously generates a voltage signal based on the sensed magnetic field (e.g., every 1ms, 5ms, or 10ms). The control device 2 can then use this voltage signal to control the electric furniture to adjust its height at a slow (half-speed) rate. On the other hand, the upper trigger switch 321 and the lower trigger switch 322 continuously generate control signals during their triggering period. The control device 2 can then use these control signals to control the electric furniture to adjust its height at a high speed.

[0087] In one embodiment, the controller of the toggle control device 2 or the controller of the electric furniture generates corresponding control commands based on signals generated by the Hall sensor 31 and / or the upper trigger switch 321 and the lower trigger switch 322. These control commands indicate the rotation direction and speed of the electric furniture's motor. More specifically, the motor's rotation direction includes forward rotation to raise the electric furniture's height and reverse rotation to lower the electric furniture's height. The motor's rotation speed includes at least half speed (e.g., 50% of the rated speed) and full speed (e.g., 100% of the rated speed). Thus, the controller can convert the sensing result of the Hall sensor 31 and / or the triggering status of the upper trigger switch 321 and the lower trigger switch 322 into corresponding control commands, thereby controlling the motor to rotate in the corresponding direction and at the corresponding speed, achieving adaptive control of the electric furniture to raise slowly, raise quickly, lower slowly, and lower quickly.

[0088] In this invention, the toggle control device 2 can be initially set by the user. In one embodiment, the display panel 210 on the grip 211 can be a touch screen, and the user can initially set the toggle control device 2 through the display panel 210. For example, when the toggle 21 is not moved (i.e., the sensing magnetic field of the Hall sensor 31 is zero), the user can set the current position of the Hall sensor 31 to the initial position A through the display panel 210. Then, when the user moves the toggle 21 upward to a first stroke, causing the Hall sensor 31 to sense the first magnetic field or output a voltage signal with a first signal strength, the user can set the current position of the Hall sensor 31 to the first upper critical position B1 through the display panel 210. Then, when the user moves the toggle 21 upward to a second stroke, causing the upper trigger switch 321 to be triggered by the upper protrusion 221 of the upper housing 22, the user can set the current position of the Hall sensor 31 to the second upper critical position C1 through the display panel 210. On the other hand, when the user moves the toggle member 21 downward to its first stroke, causing the Hall sensor 31 to sense the second magnetic field or output a voltage signal with a second signal strength, the user can set the current position of the Hall sensor 31 to the first lower critical position B2 via the display panel 210. Then, when the user moves the toggle member 21 downward to its second stroke, causing the lower trigger switch 322 to be triggered by the lower protrusion 231 of the lower housing 23, the user can set the current position of the Hall sensor 31 to the second lower critical position C2 via the display panel 210.

[0089] In this invention, the controller of the toggle control device 2 or the controller of the electric furniture records the signal strength of the voltage signal of the Hall sensor 31 at the initial position A, the first upper critical position B1, the second upper critical position C1, the first lower critical position B2, and the second lower critical position C2, as well as the signal content emitted when the upper trigger switch 321 / lower trigger switch 322 is triggered, after the user completes the initial setting action. Therefore, when the user toggle the toggle 21 and causes the Hall sensor 31 and / or the upper trigger switch 321 and the lower trigger switch 322 to emit corresponding signals, the controller can perform corresponding control on the electric furniture.

[0090] Please continue reading Figure 10 This is a schematic diagram of an electrically adjustable table with a toggle control device. Figure 10 As shown, the toggle control device 2 of this utility model can be connected to the electric height-adjustable table 1 to adjust the height of the electric height-adjustable table 1. For example, when the user pulls the toggle member 21 of the toggle control device 2 upward to the first stroke (i.e., the Hall sensor 31 approaches the first magnetic body 41), the electric height-adjustable table 1 slowly raises the table height; when the user pulls the toggle member 21 of the toggle control device 2 upward to the second stroke (i.e., the upper trigger switch 321 is triggered), the electric height-adjustable table 1 quickly raises the table height; when the user pulls the toggle member 21 of the toggle control device 2 downward to the first stroke (i.e., the Hall sensor 31 approaches the second magnetic body 42), the electric height-adjustable table 1 slowly lowers the table height; when the user pulls the toggle member 21 of the toggle control device 2 downward to the second stroke (i.e., the lower trigger switch 322 is triggered), the electric height-adjustable table 1 quickly lowers the table height.

[0091] In this way, compared with the fixed buttons used in electric height-adjustable desks in related technologies, the present invention determines the adjustment speed based on the stroke of the user toggling the lever 21, which can effectively achieve the speed adaptive function.

[0092] Please continue reading Figure 11 This is a schematic diagram of an electric television stand with a toggle control device. Figure 11As shown, the toggle control device 2 of this utility model can also be connected to the electric TV stand 6 to adjust the height of the electric TV stand 6. For example, when the user pulls the toggle member 21 of the toggle control device 2 upward to the first stroke (i.e., the Hall sensor 31 approaches the first magnetic body 41), the electric TV stand 6 slowly raises its height; when the user pulls the toggle member 21 of the toggle control device 2 upward to the second stroke (i.e., the upper trigger switch 321 is triggered), the electric TV stand 6 quickly raises its height; when the user pulls the toggle member 21 of the toggle control device 2 downward to the first stroke (i.e., the Hall sensor 31 approaches the second magnetic body 42), the electric TV stand 6 slowly lowers its height; when the user pulls the toggle member 21 of the toggle control device 2 downward to the second stroke (i.e., the lower trigger switch 322 is triggered), the electric TV stand 6 quickly lowers its height.

[0093] The above Figure 10 and Figure 11 The embodiments described herein use an electric height-adjustable table 1 and an electric TV stand 6 as examples. In other embodiments, the toggle control device 2 of this utility model can also be applied to any type of electric furniture, allowing the user to freely determine the speed at which the height of the electric furniture is adjusted by moving the toggle member 21.

[0094] In one embodiment, the electric furniture (such as the aforementioned electric height-adjustable table 1 and electric TV stand 6) may have a controller, a receiving unit, a motor, and an adjustment unit (not shown). The receiving unit receives signals output from the Hall sensor 31, the upper trigger switch 321, and the lower trigger switch 322 from the toggle control device 2. The controller converts the signals into corresponding control commands. In another embodiment, the electric furniture and the toggle control device 2 share the same controller (not shown), so that the signals are directly converted into corresponding control commands by the same controller. However, the above is only one specific embodiment of the present invention and is not intended to limit it.

[0095] The receiving unit can be implemented using various wired transmission units (e.g., transmission lines, connectors, or circuit pins) or wireless transmission units (e.g., Bluetooth modules, infrared modules, or Wi-Fi modules) to receive signals emitted by the toggle control device 2. The controller can be implemented using a Central Processing Unit (CPU), Microcontroller Unit (MCU), Programmable Logic Controller (PLC), System-on-Chips (SoC), or Field Programmable Gate Array (FPGA) to generate control commands for controlling the electric furniture based on the signals. The motor can be, for example, a DC motor, a linear motor, or a stepper motor, to operate based on the controller's control commands, driving the adjustment unit to move, thereby causing the tabletop, legs, supports, or other components of the electric furniture to rise or fall at the indicated speed in the direction indicated by the control commands.

[0096] In one embodiment, the adjustment unit may be a transmission mechanism for connecting the motor to the tabletop, legs, brackets, or other adjustable parts of the electric furniture, thereby raising or lowering the parts by the rotational movement of the motor.

[0097] With the toggle control device of this utility model, users can freely determine the speed at which electric furniture is raised or lowered by moving the toggle lever, which is quite convenient.
