Description
Technical Field
[0001] This utility model relates to the field of smart home technology, and more specifically, to a hand controller and an electric height-adjustable table. Background Technology
[0002] As a type of modern office furniture that combines functionality and comfort, electric height-adjustable desks have gained popularity in recent years due to their ability to effectively alleviate physical discomfort caused by prolonged sitting. The core mechanism of these desks lies in their built-in electric drive system, which allows for easy adjustment of the desktop height to accommodate standing or sitting postures, thus promoting a healthier work environment. For better control and adjustment of the desk's height, most electric height-adjustable desks are equipped with a hand controller. This controller is a key component for user interaction, allowing users to precisely control the desk's height adjustment via buttons or a touchscreen.
[0003] In related technologies, the hand controller is fixed in a certain position on the desktop. While this ensures convenience and stability, it also introduces other problems. First, during logistics and transportation, because the hand controller is exposed outside the desktop, it is susceptible to accidental impacts or pressure, causing the casing to crack, buttons to malfunction, or the circuit board to be damaged. Second, in daily use, when the hand controller is not in use, its fixed position may lead to accidental activation. For example, an unintentional bump while cleaning the desktop may trigger the movement of the height-adjustable desk.
[0004] Therefore, the hand controller of the electric height-adjustable table in the relevant technology is fixed on the tabletop, making it easy to be bumped or accidentally activated. Utility Model Content
[0005] The main purpose of this utility model is to provide a hand controller and an electric height-adjustable table to solve the problem that the hand controller of the electric height-adjustable table is fixed on the tabletop and is easily bumped or accidentally touched.
[0006] To achieve the above objectives, according to one aspect of the present invention, a hand controller is provided, connected to a desktop. The hand controller includes: a support connected to the desktop; a hand controller body including an operator housing and a sliding plate connected to the operator housing, the sliding plate being slidably disposed on the support; and a locking structure disposed between the support and the hand controller body, the locking structure including a swing member swayably disposed on the hand controller body, a locking protrusion disposed on one of the swing member and the support, and a locking gap disposed on the other of the swing member and the support; the swing member swings to have a locking position in which the locking protrusion engages with the locking gap and an adjusting position in which the locking protrusion disengages from the locking gap.
[0007] Furthermore, the sliding plate slides to give the hand controller body an extended position and a retracted position, and the locking gap includes a first gap and a second gap that are spaced apart; when the locking protrusion is engaged with the first gap, the hand controller body is in the retracted position; when the locking protrusion is engaged with the second gap, the hand controller body is in the extended position.
[0008] Furthermore, a locking protrusion is provided on the swing member, and a first protrusion, a second protrusion, and a third protrusion are provided at intervals on the bracket. A first gap is formed between the first protrusion and the second protrusion, and a second gap is formed between the second protrusion and the third protrusion.
[0009] Furthermore, the hand controller also includes a limiting structure disposed between the bracket and the sliding plate. The limiting structure includes a limiting post and a limiting hole extending along the sliding direction of the sliding plate. The limiting post is movably inserted into the limiting hole and is limited and engaged with the hole wall of the limiting hole. One of the limiting post and the limiting hole is disposed on the bracket, and the other of the limiting post and the limiting hole is disposed on the sliding plate.
[0010] Furthermore, the limiting post is set on the bracket, the limiting hole is set on the sliding plate, and the end of the limiting post is provided with a stop head. The diameter of the stop head is larger than the diameter of the limiting post, and the stop head can cooperate with the stop of the sliding plate. The end of the limiting hole is connected to a mounting hole, and the diameter of the mounting hole is greater than or equal to the diameter of the stop head.
[0011] Furthermore, when the limiting post is inserted into the mounting hole, the locking protrusion is located on the side of the first protrusion opposite to the second protrusion.
[0012] Furthermore, the bracket is equipped with guide rails, and the edge of the sliding plate is set inside the guide rails and cooperates with the guide rails for guidance.
[0013] Furthermore, the guide rail includes a first guide rail and a second guide rail spaced apart. An avoidance notch is provided at the edge of the sliding plate. The portion of the sliding plate located on one side of the avoidance notch forms a first plate segment, and the portion of the sliding plate located on the other side of the avoidance notch forms a second plate segment. When the limiting post is inserted into the mounting hole, the avoidance notch is correspondingly set with the first guide rail. The first plate segment is located on the side of the first guide rail away from the second guide rail, and the second plate segment is located between the first guide rail and the second guide rail.
[0014] Furthermore, the controller housing is provided with a programming hole; and / or, the hand controller also includes a wire and a protruding ring sleeved on the wire, the controller housing is provided with a wire-passing hole, the wire passes through the wire-passing hole, and the protruding ring engages with the wire-passing hole.
[0015] According to another aspect of the present invention, an electric height-adjustable desk is provided, including height-adjustable desk legs, a desktop, and a hand controller, wherein the hand controller is the aforementioned hand controller.
[0016] Applying the technical solution of this utility model, the hand controller is connected to a desktop. The hand controller includes: a bracket, a hand controller body, and a locking structure. The bracket is connected to the desktop. The hand controller body includes an operator housing and a sliding plate connected to the operator housing, the sliding plate being slidably disposed on the bracket. The locking structure is disposed between the bracket and the hand controller body. The locking structure includes a swinging member swayably disposed on the hand controller body, a locking protrusion disposed on one of the swinging member and the bracket, and a locking gap disposed on the other of the swinging member and the bracket. The swinging member swings to have a locking position where the locking protrusion engages with the locking gap, and an adjusting position where the locking protrusion disengages from the locking gap. Thus, by setting the bracket on the desktop and slidably disengaging the sliding plate of the hand controller body on the bracket, the hand controller body can slide freely on the bracket, facilitating the adjustment of the hand controller body's position relative to the desktop. The locking structure allows the controller body to lock in place after sliding to a preset position. The locking protrusion engages with the locking gap, restricting the position of the swinging component relative to the support, thus limiting the controller body's position and preventing free sliding during transport. Users can operate the swinging component to engage or disengage the locking protrusion and locking gap, facilitating locking and adjustment of the controller body's position. Furthermore, during transport or when the controller body is not in use, users can drive the swinging component to adjust its position and move the controller body relative to the support, placing it below the tabletop or in a less vulnerable location, thus extending the controller's lifespan. Therefore, the technical solution of this application effectively solves the problem in related technologies where the controller of an electric height-adjustable table is fixed on the tabletop and easily damaged by bumps or accidental activation.

[0030] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0032] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0033] In this embodiment, as Figures 1 to 4 As shown, the hand controller is connected to a desktop and includes a bracket 10, a hand controller body 20, and a locking structure. The bracket 10 is connected to the desktop. The hand controller body 20 includes an operator housing 21 and a sliding plate 22 connected to the operator housing 21. The sliding plate 22 is slidably disposed on the bracket 10. The locking structure is disposed between the bracket 10 and the hand controller body 20. The locking structure includes a swing member 30 swayably disposed on the hand controller body 20, a locking protrusion 31 disposed on the swing member 30, and a locking gap disposed on the bracket 10. The swing member 30 swings to have a locking position in which the locking protrusion 31 is engaged with the locking gap, and an adjusting position in which the locking protrusion 31 is disengaged from the locking gap.
[0034] In this way, by setting the support 10 on the desktop and slidably mounting the sliding plate 22 of the controller body 20 on the support 10, the controller body 20 can slide freely on the support 10, facilitating the adjustment of the controller body 20's position relative to the desktop. The locking structure allows the controller body 20 to engage with the locking protrusion 31 and locking gap after sliding to a preset position, thereby restricting the position of the swing member 30 relative to the support 10 and preventing the controller body 20 from sliding freely relative to the support 10 during transportation. The user can operate the swing member 30 to engage or disengage the locking protrusion 31 with the locking gap, facilitating the locking and adjustment of the controller body 20's position. In this way, when in transport mode or when the hand controller body 20 is not operated, the user can drive the swing component 30 to swing, switch the swing component 30 to the adjustment position, and drive the hand controller body 20 to move relative to the bracket 10. This moves the hand controller body 20 to a position below the tabletop or other locations less likely to be bumped or accidentally touched, thus improving the lifespan of the hand controller. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where the hand controller of an electric height-adjustable table is fixed on the tabletop and is easily bumped or accidentally touched.
[0035] In this embodiment, the swing member 30 is connected to the sliding plate 22.
[0036] In other embodiments, the swing member 30 is connected to the operator housing 21. A locking protrusion 31 is provided on the bracket 10, and a locking gap is provided on the swing member 30.
[0037] like Figures 2 to 6As shown, the sliding plate 22 slides to give the controller body 20 an extended position and a retracted position. The locking gaps include a first gap 14 and a second gap 15 spaced apart. When the locking protrusion 31 engages with the first gap 14, the controller body 20 is in the retracted position. When the locking protrusion 31 engages with the second gap 15, the controller body 20 is in the extended position. The sliding plate 22 of the controller body 20 can slide on the bracket 10, giving it both a retracted and extended position, improving the controller's flexibility. When the controller body 20 is in the retracted position, the engagement of the locking protrusion 31 with the first gap 14 keeps the controller body 20 in the retracted position, making it easy to keep the controller body 20 hidden under a table or in another location, reducing the possibility of accidental activation, reducing the risk of bumps during transportation, and reducing space occupation when the user does not need to operate the controller. When the hand controller body 20 is in the extended position, the locking protrusion 31 and the second gap 15 are engaged to keep the hand controller body 20 in the extended position, so as to fix the hand controller body 20 in an easy-to-operate place, making it convenient for users to control the lifting and lowering, thereby enhancing the user experience.
[0038] like Figure 4 and Figure 6 As shown, the locking protrusion 31 is disposed on the swing member 30. The bracket 10 is provided with a first protrusion 11, a second protrusion 12, and a third protrusion 13 spaced apart. A first gap 14 is formed between the first protrusion 11 and the second protrusion 12, and a second gap 15 is formed between the second protrusion 12 and the third protrusion 13. The first gap 14 and the second gap 15 are machined by the arrangement of the first protrusion 11, the second protrusion 12, and the third protrusion 13, which is simple to manufacture and maintains the structural strength of the bracket 10. Furthermore, the user only needs to swing the swing member 30 to switch the locking protrusion 31 between the first gap 14 and the second gap 15, without complicated manual operation.
[0039] like Figures 2 to 6As shown, the hand controller also includes a limiting structure disposed between the bracket 10 and the sliding plate 22. The limiting structure includes a limiting post 16 and a limiting hole 221 extending along the sliding direction of the sliding plate 22. The limiting post 16 is movably inserted into the limiting hole 221 and engages with the hole wall of the limiting hole 221. The limiting post 16 is disposed on the bracket 10, and the limiting hole 221 is disposed on the sliding plate 22. The addition of a limiting structure between the bracket 10 and the sliding plate 22 effectively prevents excessive displacement of the hand controller body 20 during the sliding process, ensuring that it can automatically stop after sliding to a specific position and will not exceed the preset sliding range due to inertia. This design not only improves the stability of the hand controller body 20 during sliding but also reduces the possibility of the hand controller body 20 detaching from the bracket 10. Furthermore, the structure of the limiting post 16 and the limiting hole 221 is simple and easy to process and assemble.
[0040] In other embodiments, the limiting hole 221 is provided on the bracket 10, and the limiting post 16 is provided on the sliding plate 22.
[0041] like Figures 2 to 7 As shown, a limiting post 16 is mounted on the bracket 10, and a limiting hole 221 is mounted on the sliding plate 22. A stop head 17 is provided at the end of the limiting post 16, with a diameter larger than that of the limiting post 16, allowing the stop head 17 to engage with the sliding plate 22. A mounting hole 222 is connected to the end of the limiting hole 221, with a diameter greater than or equal to that of the stop head 17. The stop head 17 limits the movement of the sliding plate 22 along the axis of the limiting post 16, reducing the possibility of the sliding plate 22 disengaging from the limiting post 16 along this axis, thus making the sliding connection between the bracket 10 and the sliding plate 22 more stable and reliable. The mounting hole 222 is designed to facilitate the installation of the stop head 17: the stop head 17 is inserted into the mounting hole 222 so that the limiting post 16 can enter the mounting hole 222, thereby facilitating the movement of the limiting post 16 into the limiting hole 221 that communicates with the mounting hole 222 and performing a limiting engagement.
[0042] like Figures 2 to 6As shown, when the limiting post 16 is inserted into the mounting hole 222, the locking protrusion 31 is located on the side of the first protrusion 11 facing away from the second protrusion 12. This allows the limiting post 16 to be positioned within the limiting hole 221, which communicates with the mounting hole 222, when the locking protrusion 31 is inserted into the first gap 14 between the first protrusion 11 and the second protrusion 12. Thus, when the hand controller body 20 is in the retracted position, this arrangement reduces the possibility of the limiting post 16 and the stop head 17 dislodging from the mounting hole 222, making the sliding connection between the sliding plate 22 and the bracket 10 more reliable. When the limiting post 16 is inserted into the mounting hole 222, the sliding plate 22 is in its initial position on the bracket 10. By driving the sliding plate 22 to move, the locking protrusion 31 is engaged with either the first gap 14 or the second gap 15, further reducing the possibility of the limiting post 16 and the stop head 17 dislodging from the mounting hole 222.
[0043] like Figures 2 to 5 As shown, a guide rail is provided on the bracket 10, and the edge of the sliding plate 22 is disposed within the guide rail and engages with the guide rail for guidance. The guide rail design allows the sliding plate 22 to slide more smoothly on the bracket 10, enabling it to slide in a preset direction, thus facilitating the switching of the hand controller body 20 between the extended and retracted positions. The guide rail design improves the durability of the sliding plate 22, reduces component wear caused by sliding friction, and thus extends the service life of the hand controller.
[0044] like Figure 7As shown, the guide rail includes a first guide rail 18 and a second guide rail 19 spaced apart. A clearance notch 223 is provided at the edge of the sliding plate 22. The portion of the sliding plate 22 located on one side of the clearance notch 223 forms a first plate segment 224, and the portion of the sliding plate 22 located on the other side of the clearance notch 223 forms a second plate segment 225. When the limiting post 16 passes through the mounting hole 222, the clearance notch 223 corresponds to the first guide rail 18, the first plate segment 224 is located on the side of the first guide rail 18 facing away from the second guide rail 19, and the second plate segment 225 is located between the first guide rail 18 and the second guide rail 19. Thus, the clearance notch 223, the first guide rail 18, and the second guide rail 19 facilitate the installation of the hand controller body 20 onto the bracket 10 along the axial direction of the limiting post 16. During the installation of the hand controller body 20 onto the bracket 10, the first guide rail 18 can avoid contact with the clearance notch 223, the first plate segment 224 can avoid contact with the first guide rail 18, and the second plate segment 225 can avoid contact with the space between the first guide rail 18 and the second guide rail 19. This allows the stop head 17 to be inserted into the mounting hole 222, and the limiting post 16 to extend into the mounting hole 222. Then, by driving the sliding plate 22 to move along the extension direction of the limiting hole 221, the first guide rail 18 can be guided to engage with the first plate segment 224, and the second guide rail 19 can be guided to engage with the second plate segment 225. The above-described structure is simple, facilitates the assembly of the hand controller, and does not affect the sliding of the hand controller body 20 relative to the bracket 10.
[0045] like Figures 2 to 5 As shown, the controller housing 21 is provided with a programming hole 211. The programming hole 211 on the controller housing 21 provides a convenient way to update the software of the controller. Without removing the controller housing 21, technicians can easily connect to a programming device through the programming hole 211 to upgrade the software or troubleshoot the controller. This not only shortens service response time and reduces the time users spend waiting for repairs or replacements, but also lowers maintenance costs. The controller also includes a cable and a protruding ring 40 sleeved on the cable. The controller housing 21 is provided with a wire-passing hole 212, through which the cable passes. The protruding ring 40 engages with the wire-passing hole 212. This detailed design not only ensures a secure connection between the cable and the controller body 20, avoiding signal interference or safety issues caused by loose wiring, but also makes the wiring layout neater and more organized. In addition, the convex ring 40 helps protect the interface of the cable during repeated plugging and unplugging, extending the service life of the cable.
[0046] In this embodiment, the wire hole 212 is semi-circular.
[0047] In other embodiments, the operator housing 21 is provided with a programming hole 211. Alternatively, the hand controller also includes a wire and a protruding ring 40 sleeved on the wire, the operator housing 21 is provided with a wire-passing hole 212, the wire passes through the wire-passing hole 212, and the protruding ring 40 engages with the wire-passing hole 212.
[0048] In this embodiment, the bracket 10 is fixed to the desktop with screws. The controller housing 21 includes an upper cover and a lower cover, which are connected by screws and clips, forming an installation space between them. A silicone button is provided on the upper cover, protruding 0.8mm from the surface of the upper cover to prevent hand jamming when pressed. The controller also includes a PCBA and a vibration motor disposed within the installation space. The PCBA has a display screen and a Type-C port, and the upper cover has a black high-transparency area corresponding to the display screen to ensure display quality. The vibration motor is connected to the PCBA via a spring contact, enabling a sedentary vibration reminder function.
[0049] This application also provides an electric height-adjustable desk, which includes height-adjustable legs, a desktop, and a hand controller, wherein the hand controller is the aforementioned hand controller. Because the aforementioned hand controller solves the problem in related technologies where the hand controller of an electric height-adjustable desk is fixed to the desktop and easily bumped or accidentally activated, the electric height-adjustable desk with this hand controller can solve the same technical problem.
[0050] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.
[0051] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0052] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
