Description

Easy-to-use hand controller and height-adjustable table Technical Field

[0001] This utility model relates to the field of height-adjustable desks, and in particular to a convenient hand controller and a height-adjustable desk. Background Technology

[0002] A height-adjustable desk is an essential office and personal item. Widely used in Europe and America, it is gradually gaining acceptance and widespread application in China as well. Its value lies in helping office workers move from prolonged sitting to standing work. Electric height-adjustable desks typically come equipped with a hand controller, allowing users to adjust the height by controlling the electric legs. The hand controller usually employs methods such as pressing (single press to trigger the switch or long press to control height) or rotating (turning the knob to the desired position to trigger the switch or rotating it while simultaneously controlling height).

[0003] Most height-adjustable desk controllers on the market currently use traditional button, knob, or paddle operation methods, requiring users to adjust the desk's height using these methods. However, these traditional operation methods suffer from inconvenience in blind operation, lack of memory keys, or other operational difficulties, impacting the user experience. Summary of the Invention

[0004] This utility model provides a hand controller and a height-adjustable table that are easy to operate, easy to install on the tabletop, and easy to control.

[0005] On the one hand, this utility model provides a convenient hand controller for controlling a height-adjustable table, which includes a housing, a main control module, a memory controller, and a height-adjustable controller;

[0006] The housing includes a docking shell and a control shell. The docking shell has a docking surface for abutting against the bottom surface of the tabletop of the lifting table. The control shell is connected to one horizontal end of the docking shell. The top of the control shell protrudes upward from the docking surface. The side of the control shell facing the docking shell is an abutting surface for abutting against the side edge of the tabletop.

[0007] The memory controller is electrically connected to the main control module; the memory controller is a push-button type and is located on the side of the control housing opposite to the docking housing; the lifting controller includes a lifting control component and a lifting sensing module, the lifting control component is vertically movably disposed on one side of the control housing in the horizontal direction; the lifting sensing module is electrically connected to the main control module, and the lifting control component is connected to the lifting sensing module, so that the lifting sensing module senses the vertical movement of the lifting control component and converts it into an electrical signal and transmits it to the main control module;

[0008] When the lifting control component moves downward, the main control module controls the table to descend;

[0009] When the lifting control component moves upward, the main control module controls the table to rise.

[0010] The lifting control component is block-shaped.

[0011] Wherein, the bottom surface of the lifting control component is lower than the docking surface.

[0012] The lower surfaces of the lifting control component, the docking shell, and the control shell are flush.

[0013] The top surface of the lifting control component is lower than the upper surface of the table.

[0014] The lifting control component is slidably mounted on the control housing along a vertical straight line.

[0015] The lifting control component is rod-shaped, with one end located inside the control housing and rotatably connected to the control housing around the horizontal direction, and the other end located outside the control housing for user operation.

[0016] The lifting control component and the control housing are arranged along the edge of the table.

[0017] The lifting control component is rotatably connected to the control housing about a vertical direction and can rotate between a first position and a second position.

[0018] The control housing is provided with a limiting hole, a movable hole, and a guide hole. The limiting hole is located on one side of the control housing along the edge of the table and is used to restrict the vertical movement of the lifting control component. The movable hole is located on the side of the control housing away from the table and is used to allow the lifting control component to move vertically. The guide hole is strip-shaped, with its two ends connected to the limiting hole and the guide hole, respectively, and is used to allow the lifting control component to rotate vertically.

[0019] When the lifting control component is in the first position, the lifting control component passes through the limiting hole, and the lifting control component is located on one side of the control housing in the direction of the table edge.

[0020] When the lifting control component is in the second position, the lifting control component passes through the movable hole, and the lifting control component is located on the side of the control housing opposite to the table.

[0021] On the other hand, this utility model also provides a height-adjustable table, including a tabletop and the aforementioned convenient hand controller, wherein the hand controller is installed on the tabletop.

[0022] This utility model provides a user-friendly hand controller and height-adjustable desk. When installing the hand controller onto the desk, there's no need to precisely align the housing with the desk's edge. Simply align the hand controller with the bottom surface of the desk and the side edge of the desk; this ensures proper positioning and avoids any positional deviation from the desk's edge, simplifying installation. Users lower the desk by moving the lifting control downwards and raise it by moving it upwards, achieving a logically sound control method. This eliminates the need to look directly at the buttons, enabling blind operation. The simple structure effectively improves user experience and ease of use. The up-and-down movement of the lifting control differs from the pressing operation of the memory controller, allowing users to clearly distinguish between the two and achieve efficient desk control.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the diagram, units with similar structures are represented by the same labels.

[0031] As shown in Figure 1, the first embodiment of this utility model provides a height-adjustable desk, including a desk panel 200 and a conveniently operated hand controller 100, which is mounted on the desk panel 200. The hand controller 100 includes a housing 1, a main control module (not shown in the figure), a memory controller 2, and a height adjustment controller 3. The memory controller 2 and the height adjustment controller 3 are both electrically connected to the main control module to control the height adjustment of the desk panel 200 and to memorize preset heights for easy automatic height adjustment in the future. The memory controller 2 and the height adjustment controller 3 are both housed in the housing 1, which is assembled with the desk panel 200 to mount the hand controller 100 onto the desk panel 200.

[0032] The main control module can be housed inside the housing 1 and electrically connected to the lifting drive device of the height-adjustable table, or it can be located outside the housing 1, for example, on the lifting drive device. The main control module can be electrically connected to the lifting drive device via cable, or it can be connected wirelessly via Bluetooth, WiFi, or other methods.

[0033] As shown in Figure 2, the housing 1 includes a docking shell 11 and a control shell 12. The docking shell 11 has a docking surface 110 for abutting against the bottom surface of the tabletop 200. The control shell 12 is connected to one horizontal end of the docking shell 11, and the top surface of the control shell 12 protrudes upward from the docking surface 110, so that the overall shape of the housing 1 is approximately L-shaped. The side of the control shell 12 facing the docking shell 11 is an abutting surface 120 for abutting against the side edge of the tabletop 200.

[0034] When installing the hand controller 100 onto the tabletop 200, there is no need to deliberately align the housing 1 with the edge of the tabletop 200. Simply align the mating surface 110 with the bottom surface of the tabletop 200 and the mating surface 120 with the side edge of the tabletop 200 to achieve the alignment of the hand controller 100 and the tabletop 200. This will prevent any positional deviation from the edge of the tabletop 200 and facilitate installation.

[0035] As shown in Figure 3, the memory controller 2 is a push-button type and is located on the side of the control housing 12 opposite to the docking housing 11, so as to facilitate the user to press the memory controller 2. The memory controller 2 includes multiple memory buttons, which are arranged along the edge of the tabletop 200. Some of the memory buttons can be used to store, delete, or modify a predetermined height value, and some of the memory buttons are used to mark the sequence number of multiple predetermined height values.

[0036] The lifting controller 3 includes a lifting control component 31 and a lifting sensing module (not shown in the figure). The lifting control component 31 is vertically movably disposed on one side of the control housing 12 in the horizontal direction. The lifting sensing module is electrically connected to the main control module, and the lifting control component 31 is connected to the lifting sensing module so that the lifting sensing module can sense the vertical movement of the lifting control component 31, convert it into an electrical signal, and transmit it to the main control module.

[0037] When the lifting control component 31 moves downward, the main control module controls the tabletop 200 to descend; when the lifting control component 31 moves upward, the main control module controls the tabletop 200 to rise. The user lowers the tabletop 200 by moving the lifting control component 31 downward and raises it by moving it upward, achieving a logically consistent control method for the height-adjustable table. This eliminates the need to look directly at the buttons, enabling blind operation. The simple structure effectively improves the user experience and ease of use. The up-and-down movement of the lifting control component 31 differs from the pressing operation of the memory controller 2, allowing users to clearly distinguish between the two and achieve efficient height-adjustable table control.

[0038] In this embodiment, the lifting sensor module is housed within the control housing 12 to facilitate electrical connection between the lifting sensor module and the main control module. Alternatively, in other embodiments, the lifting sensor module can be housed within the lifting control component 31, and a protruding structure can be provided on the control housing 12 extending into the lifting control component to trigger the lifting sensor module.

[0039] The lifting sensing module can use a variable resistance sensor, Hall effect sensor, pressure sensor or other sensing module that can sense the precise position of the lifting control component 31, so as to control the lifting speed of the table 200 according to the displacement of the lifting control component 31. Alternatively, the lifting sensing module can use a simple photoelectric sensor that only outputs simple discrete signals of up and down to reduce costs.

[0040] As shown in Figure 3, the lifting controller 3 may also include a reset elastic element 32, which is connected to the lifting control element 31 so that the lifting control element 31 is held in the middle position when there is no external force. After the user moves the lifting control element 31, the lifting control element 31 can be automatically reset by the reset elastic element 32 for convenient use.

[0041] In this embodiment, the lifting control component 31 and the control housing 12 are arranged along the edge of the tabletop 200 to prevent the lifting control component 31 from protruding too much from the edge of the tabletop 200 and causing accidental activation. Of course, in other embodiments, the lifting control component 31 may also be located on the side of the control housing 12 away from the tabletop 200.

[0042] In this embodiment, the lifting control component 31 is block-shaped to facilitate processing and manufacturing, and matches the overall shape of the hand controller 100 and the structure of the table 200 to ensure the overall appearance and structure are coordinated.

[0043] The bottom surface of the lifting control component 31 is lower than the docking surface 110 of the docking shell 11, so that the bottom surface of the lifting control component 31 is lower than the bottom surface of the table 200, that is, the lifting control component 31 protrudes downward from the table 200, making it convenient for the user to move the lifting control component 31 upward.

[0044] The lower surfaces of the lifting control component 31, the docking shell 11, and the control shell 12 are flush, which facilitates the processing and molding of the docking shell 11 and the control shell 12, and also facilitates the assembly and positioning between the lifting control component 31 and the control shell 12, while also facilitating the packaging of the entire hand controller 100.

[0045] The top surface of the lifting control component 31 is lower than the upper surface of the tabletop 200, so that the lifting control component 31 does not protrude from the upper surface of the tabletop 200. When the user is working on the tabletop 200, they will not accidentally press the lifting control component 31, causing the tabletop 200 to drop. The top surface of the control housing 12 is also lower than the upper surface of the tabletop 200 to prevent the control housing 12 from protruding from the tabletop 200 and affecting the user's work. Preferably, the top surface of the control housing 12 is flush with the top surface of the lifting control component 31, so that the overall shape of the hand controller 100 is simple and beautiful, which is conducive to packaging.

[0046] In this embodiment, the lifting control component 31 is slidably disposed on the control housing 12 along a vertical straight line to facilitate the cooperation and connection between the block-shaped lifting control component 31 and the control housing 12.

[0047] In the second embodiment of this utility model, as shown in Figure 4, the lifting control member 31 is rod-shaped, with one end located inside the control housing 12 and rotatably connected to the control housing 12 about the horizontal direction, and the other end located outside the control housing 12 for user operation. The rod-shaped lifting control member 31 has a simple structure, is easy to operate, and is low in cost. By rotatably connecting the lifting control member to the control housing 12 about the horizontal direction, the other end of the lifting control member 31 can be vertically movable. Other structures in this embodiment can be the same as in the first embodiment, and will not be described again here.

[0048] In the first and second embodiments described above, the lifting control member 31 is disposed on one side of the control housing 12 along the edge of the tabletop 200 and is vertically movable. In another embodiment, such as the third embodiment of this utility model, the lifting control member 31 is rotatably connected to the control housing 12 about a vertical direction, and can rotate between a first position and a second position. The control housing 12 is provided with a limiting hole 121, a movable hole 122, and a guide hole 123. The limiting hole 121 is located on one side of the control housing 12 along the edge of the tabletop 200, used to restrict the vertical movement of the lifting control member 31; the movable hole 122 is located on the side of the control housing 12 away from the tabletop 200, used to allow the lifting control member 31 to move vertically; the guide hole 123 is strip-shaped, with its two ends connected to the limiting hole 121 and the guide hole 123 respectively, used to allow the lifting control member 31 to rotate vertically.

[0049] As shown in Figure 5, when the lifting control component 31 is in the first position (i.e., the position of the limiting hole 121), the lifting control component 31 passes through the limiting hole 121, and the lifting control component 31 is located on one side of the control housing 12 in the direction of the edge of the table 200. The limiting hole 121 restricts the vertical movement of the lifting control component 31, thereby preventing accidental operation, and also allows the lifting control component 31 to be relatively close to the table 200, reducing the space it occupies.

[0050] When the lifting control component 31 rotates, the lifting control component 31 can move along the guide hole 123.

[0051] As shown in Figure 6, when the lifting control component 31 is in the second position (i.e., the position of the movable hole 122), the lifting control component 31 passes through the movable hole 122. The lifting control component 31 is located on the side of the control housing 12 opposite to the tabletop 200, which facilitates user operation of the lifting control component 31. Using the movable hole 122, the lifting control component 31 can move vertically, allowing the user to move the lifting control component 31 up and down, thereby raising or lowering the tabletop 200.

[0052] In the third embodiment of this utility model, when the user needs to adjust the height of the tabletop 200, the lifting control component 31 can be rotated to the second position. After the adjustment is completed, the lifting control component 31 can be rotated back to the first position, so that the lifting control component 31 cannot move vertically, thereby avoiding accidental operation by the user during office work.

[0053] In this embodiment, the lifting sensor module is disposed within the control housing 12. When the lifting control component 31 is in the first position, it is separated from the lifting sensor module to effectively prevent the tabletop 200 from lifting due to vertical movement of the lifting control component 31 in the first position. When the lifting control component 31 is in the second position, it is connected to the lifting sensor module, and vertical movement of the lifting control component 31 can trigger the lifting sensor module. The lifting control component 31 can be connected to the control housing 12 via a universal joint, allowing it to rotate both vertically and horizontally.

[0054] In other embodiments, the lifting sensor module and the lifting control component 31 can also be connected to form an integral structure. This integral structure can rotate vertically relative to the control housing 12, thereby allowing the lifting control component 31 to rotate vertically as well. Specifically, the lifting sensor module can be rotatably connected to the control housing 12, while the lifting control component 31 and the lifting sensor module are engaged in a horizontal rotational cooperation.

[0055] In this embodiment, the lifting control component 31 is rod-shaped, but it can also be block-shaped in other embodiments. The other structures of the hand controller 100 can be the same as in the first embodiment, and will not be described again here.

[0056] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
