Description

Technical Field

[0001] This disclosure relates to the field of intelligent electric furniture technology, and in particular to an electric hand controller and a height-adjustable table. Background Technology

[0002] With the continuous development of smart furniture, more and more companies are creating different types of smart products. Among them, height-adjustable desks, as part of smart living and smart office, allow people to enjoy a healthy lifestyle and work style that alternates between standing and sitting. Typically, to adjust the desktop height, a hand controller is used for vertical adjustment to accommodate more users who have specific requirements for desktop height, such as the electric desk hand controller disclosed in existing patents CN211533123U and CN221488083U.

[0003] When the controller is not cleaned for a long time, dust adheres to its surface, and some dust enters the controller's interior, causing dust to accumulate in the button sensing parts of the circuit board inside. This reduces the sensitivity of the buttons when the user operates them, and may even cause the sensing spring to fail to detect the button's movement. This significantly diminishes the user experience when adjusting the height of the height-adjusting desk using the buttons.

[0004] In addition, when using the controller normally, for example, when the user is adjusting the desktop height, they will press the corresponding adjustment button. At this time, a button that is too close to the adjustment button will also sense the hand movement. In this way, the sensing springs corresponding to the adjustment button and the sensing springs corresponding to the nearby buttons will receive the corresponding signals of the hand movement, and then perform actions other than adjusting the desktop height, such as desktop height locking or desktop height memory. This causes the sensing springs corresponding to adjacent buttons to interfere with each other, thus making it impossible to adjust the desktop height normally.

[0005] Therefore, a hand controller is needed that can prevent dust accumulation on the sensing part of the circuit board and prevent interference from adjacent buttons. Utility Model Content

[0006] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an electric hand controller and a height-adjustable table that can prevent dust accumulation on the sensing part and reduce interference between adjacent buttons.

[0007] The purpose of this disclosure is achieved through the following technical solution:

[0008] An electric hand controller includes a housing, a power supply board, a sealing ring, and an insulating ring. The housing has a receiving cavity, and multiple button sensing blocks protrude from the housing, all located within the receiving cavity. Each button sensing block has a sensing groove facing the receiving cavity. The outer side of the housing has a deformable button area, and each of the multiple button sensing blocks corresponds to the deformable button area. The power supply board includes a main circuit board and multiple sensing springs. The main circuit board is located within the receiving cavity, and each sensing spring is located within a corresponding sensing groove. The sensing acquisition end of the main circuit board is electrically connected to the sensing spring, and the sensing portions of the multiple sensing springs are projected onto the deformable button area. Each button sensing block abuts against the main circuit board through the sealing ring, so that the main circuit board seals the opening of the sensing groove. The insulating ring is disposed on the inner wall of the sensing groove.

[0009] In one embodiment, the housing has a power interface, and the power supply board further includes power pins that are electrically connected to the power supply terminal of the main circuit board. A portion of the power pins is located at the power interface.

[0010] In one embodiment, the housing includes a front shell and a bottom shell connected together. The deformable button area and the button sensing block are both disposed on the front shell, and the deformable button area and the button sensing block are disposed opposite to the front shell. The sensing spring is disposed towards the front shell.

[0011] In one embodiment, the outer casing further includes a screw, the front casing has a screw hole, the bottom casing has a through hole, the helical portion of the screw passes through the through hole and the screw hole in sequence, and the top of the screw abuts against the bottom casing.

[0012] In one embodiment, the bottom shell is further provided with a mounting hole, which communicates with the through hole, and the top of the screw is located inside the mounting hole.

[0013] In one embodiment, the outer side of the housing also has a status display area, the power supply board also includes a display screen, the status display terminal of the circuit main board is electrically connected to the display screen, and the output terminal of the display screen is arranged outward through the status display area.

[0014] In one embodiment, the display screen is a digital display screen.

[0015] In one embodiment, the sealing ring is a silicone ring.

[0016] In one embodiment, the thickness of the insulating ring is 2mm-3mm.

[0017] A height-adjustable desk includes a height-adjustable desk body and an electric hand controller as described in any of the above embodiments, wherein the drive output terminal of the electric hand controller is electrically connected to the height-adjustable drive controlled terminal of the height-adjustable desk body.

[0018] Compared with the prior art, this disclosure has at least the following advantages:

[0019] The aforementioned electric hand controller has a sealing ring and an insulating ring. The sealing ring is positioned between the main circuit board and the button sensing block, allowing the sealing ring to abut against both the button sensing block and the main circuit board, thereby isolating the sensing groove from the receiving cavity. Since the sensing spring is located inside the sensing groove, external dust will not penetrate into the sensing groove, thus preventing the decrease in sensing sensitivity caused by dust accumulation on the sensing spring. In addition, the insulating ring is positioned on the inner wall of the sensing groove, confining the sensing area of ​​the sensing spring to the sensing groove and preventing it from spreading to other areas, thereby preventing interference between adjacent sensing springs.

[0032] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0033] Please see Figure 1 This is an electric hand controller 10, which is an embodiment of the present utility model.

[0034] Combination Figures 2 to 5As shown, the electric hand controller 10 includes a housing 100, a power supply board 200, a sealing ring 300, and an insulating ring 400. The housing 100 has a receiving cavity 100a, and a plurality of button sensing blocks 110 protrude from the housing 100. The plurality of button sensing blocks 110 are all located within the receiving cavity 100a. The button sensing blocks 110 have sensing grooves 110a, which face the receiving cavity 100a. The outer side of the housing 100 has a deformable button area 101, and the plurality of button sensing blocks 110 correspond to the deformable button area 101. The power supply board 200 includes a main circuit board 210 and a plurality of sensing springs 220. The circuit board 210 is located inside the accommodating cavity 100a, and each sensing spring 220 is located inside the corresponding sensing groove 110a. The sensing acquisition end of the circuit board 210 is electrically connected to the sensing spring 220. The sensing parts of multiple sensing springs 220 are projected into the deformable button area 101. Each button sensing block 110 abuts against the circuit board 210 through a sealing ring 300, so that the circuit board 210 blocks the opening of the sensing groove 110a. Thus, the sensing groove 110a is isolated from the accommodating cavity 100a under the combined action of the sealing ring 300 and the circuit board 210. The insulating ring 400 is set on the inner wall of the sensing groove 110a.

[0035] In this embodiment, the electric hand controller 10 has a sealing ring 300 and an insulating ring 400. The sealing ring 300 is disposed between the circuit board 210 and the button sensing block 110, so that the sealing ring 300 abuts against the button sensing block 110 and the circuit board 210 respectively, thereby isolating the sensing groove 110a from the receiving cavity 100a. Since the sensing spring 220 is located in the sensing groove 110a, external dust will not penetrate into the sensing groove 110a, thereby preventing the decrease in sensing sensitivity caused by dust accumulation in the sensing spring 220. In addition, the insulating ring 400 is disposed on the inner wall of the sensing groove 110a, so that the sensing area of ​​the sensing spring 220 is limited to the sensing groove 110a and will not spread to other areas, thereby preventing adjacent sensing springs 220 from interfering with each other.

[0036] like Figure 6 and Figure 7 As shown, in one embodiment, the housing 100 has a power interface 120, and the power supply board 200 also includes a power pin 230, which is electrically connected to the power supply terminal of the main circuit board 210. A portion of the power pin 230 is located at the power interface 120. It can be understood that when using the electric hand controller 10, it can be powered by an external power source. Specifically, the electric hand controller 10 is powered by connecting wires to both the external power source and the power interface 120.

[0037] like Figure 2 , Figure 4 and Figure 7As shown, in one embodiment, the outer shell 100 includes a front shell 1100 and a bottom shell 1200 connected to each other. A deformable button area 101 and a button sensing block 110 are both disposed on the front shell 1100, and are positioned opposite to the front shell 1100. A sensing spring 220 is positioned facing the front shell 1100. In this embodiment, the front shell 1100 and the bottom shell 1200 can be connected by snap-fit, fastening, or screws. It can be understood that after the electric hand controller 10 is installed, the front shell 1100 faces outwards for user operation. Therefore, the deformable button area 101 and the button sensing block 110 are both disposed on the front shell 1100, the sensing spring 220 is positioned facing the front shell 1100, and the button sensing block 110 and the sensing spring 220 are located on the same side of the front shell 1100.

[0038] In another embodiment, the power interface 120 is disposed on the bottom housing 1200.

[0039] like Figure 4 and Figure 7 As shown, in one embodiment, the outer shell 100 further includes a screw 1300. The front shell 1100 has a screw hole 1101, and the bottom shell 1200 has a through hole 1201. The helical portion of the screw 1300 passes through the through hole 1201 and the screw hole 1101 in sequence, and the top of the screw 1300 abuts against the bottom shell 1200. In this embodiment, the outer shell 100 and the bottom shell 1200 can be connected by the screw 1300. Specifically, when assembling the electric hand controller 10, after installing the power supply board 200, the front shell 1100 and the bottom shell 1200 are connected by the screw 1300 passing through the through hole 1201 and the screw hole 1101. Further, the bottom shell 1200 also has a mounting hole 1202, which communicates with the through hole 1201, and the top of the screw 1300 is located in the mounting hole 1202.

[0040] like Figure 1 , Figure 5 and Figure 7 As shown, in one embodiment, the outer side of the housing 100 also has a status display area 102, and the power supply board 200 also includes a display screen 240. The status display terminal of the main circuit board 210 is electrically connected to the display screen 240, and the output terminal of the display screen 240 is set outward through the status display area 102. It can be understood that when the display screen 240 is set, when the user adjusts the height of the adjustable desk, sets the upper / lower limit, or memorizes the height, the main circuit board 210 receives the user's operation signal and displays the relevant signal on the display screen 240 to inform the user. Furthermore, the display screen 240 is a digital display screen; therefore, after the main circuit board 210 receives the user's operation signal, the signal is represented in the form of numbers or English symbols, such as the current desktop height, the memorized status symbol, the height lock symbol, etc.

[0041] In one embodiment, the sealing ring 300 is a silicone ring. In another embodiment, the sealing ring 300 may also be a silicone grease ring, thereby ensuring the airtightness between the button sensing block 110 and the circuit board 210.

[0042] In one embodiment, the thickness of the insulating ring 400 is 2mm-3mm. In this embodiment, the thickness of the insulating ring 400 is 2mm, so that the sensing area of ​​each sensing spring 220 is limited within the sensing groove 110a, and the sensing intensity of the sensing spring 220 in the sensing groove 110a will not be significantly reduced. Therefore, the user can adjust the settings or the desktop height normally without being interfered with by the signals received by other sensing springs 220.

[0043] This disclosure also provides a height-adjustable desk, including a height-adjustable desk body and an electric hand controller 10 as described in any of the above embodiments. The drive output terminal of the electric hand controller 10 is electrically connected to the height-adjustable drive controlled terminal of the height-adjustable desk body. In this embodiment, the height-adjustable desk body includes a desktop, a telescopic rod, desk legs, and a height-adjustable drive. The desktop is fixedly connected to the telescopic rod, and the telescopic rod is movably connected to the desk legs. The height-adjustable drive is installed at the bottom of the desktop, and the control output terminal of the height-adjustable drive is connected to the telescopic rod. The signal output terminal of the circuit board 210 is electrically connected to the signal receiving terminal of the height-adjustable drive. The height-adjustable drive controlled terminal refers to the height-adjustable drive and the telescopic rod. When the user adjusts the desktop height, the circuit board 210 receives the height adjustment signal through the sensing spring 220, and then sends the signal to the height-adjustable drive to drive the telescopic frame of the height-adjustable desk body to rise or fall, thereby completing the adjustment of the desktop height.

[0044] Compared with the prior art, this disclosure has at least the following advantages:

[0045] The aforementioned electric hand controller 10 has a sealing ring 300 and an insulating ring 400. The sealing ring 300 is disposed between the circuit board 210 and the button sensing block 110, so that the sealing ring 300 abuts against the button sensing block 110 and the circuit board 210 respectively, thereby isolating the sensing groove 110a from the receiving cavity 100a. Since the sensing spring 220 is located inside the sensing groove 110a, external dust will not penetrate into the sensing groove 110a, thereby preventing the decrease in sensing sensitivity caused by dust accumulation in the sensing spring 220. In addition, the insulating ring 400 is disposed on the inner wall of the sensing groove 110a, so that the sensing area of ​​the sensing spring 220 is limited to the sensing groove 110a and will not spread to other areas, thereby preventing adjacent sensing springs 220 from interfering with each other.

[0046] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
