Description

Technical Field

[0001] The utility model relates to the technical field of seats, and particularly relates to a hand controller and an electric lifting table having the same. Background Art

[0002] Electric lifting tables are widely used because they can be adjusted in height, such as desks, office desks, bookshelves, dining tables, etc. with adjustable height. For easy operation, the electric lifting tables in related technologies are generally equipped with hand controllers. Users can control the electric lifting table legs in the electric lifting table to perform lifting actions through the hand controller, so as to realize the height adjustment of the electric lifting table. When using a conventional hand controller on the market, it is necessary to observe the height change of the electric lifting table while pressing or turning the operation, and rely on the user's own feeling to judge whether the height is appropriate. There are problems of poor accuracy in height adjustment and the need for repeated adjustments.

[0003] Therefore, some hand controllers in related technologies are designed to be able to automatically lift to a set height value according to the user's height. The set height value is a desktop height value theoretically adapted to the height obtained by the enterprise through market research and calculation. However, such hand controllers generally have complex structures to obtain the user's height data. For example, a touch screen is set, and the user inputs the height data through the numerical control screen; or a camera is set to obtain the user's height data by collecting images and designing algorithms. The above structural design makes the overall size and cost of the hand controller very high. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hand controller and an electric lifting table having the same, which can automatically adjust to a set height value according to the user's height data, and have low manufacturing cost and small size.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0010] Preferably, both the cover plate and the display screen are fixedly disposed on the pressing member. The cover plate has a transparent area corresponding to the position of the display screen. The pressing member has a first position and a second position relative to the electronic control board. The hand controller further includes an elastic member that presses on the pressing member so that the pressing member has a tendency to slide to the first position.

[0011] During the process of the pressing member moving from the first position to the second position, the pressing member presses on the trigger button of the electronic control board to trigger the electronic control board.

[0012] Preferably, the pressing member is slidably disposed in the first shell. The cover plate and the first shell are in clearance fit. The pressing member includes a pressing plate, a limiting claw, and a pressing block for pressing on the trigger button. Both the limiting claw and the pressing block are formed on the pressing plate.

[0013] The electronic control board is provided with a through hole for the limiting claw to pass through. The claw portion of the limiting claw passes through the through hole and cooperates with the electronic control board to limit the moving stroke of the pressing member.

[0014] Preferably, the first rotating shell further includes a connecting plate disposed in the first shell. The connecting plate is located between the pressing plate and the electronic control board. The connecting plate is provided with an opening for the limiting claw and the pressing block to pass through.

[0015] One end of the elastic member is fixedly disposed on the pressing plate, and the other end abuts against the connecting plate.

[0016] Preferably, an installation groove is disposed on a side of the pressing plate facing the cover plate. The display screen is positioned in the installation groove, and a connection hole is disposed on the bottom wall of the installation groove.

After reaching the user's own height data, the pressing member is used to trigger the electronic control board, and the electronic control board can control the electric lifting table to lift to a height corresponding to the user height data. That is to say, by presetting the height value corresponding to the user height data, a reference standard is given to the user, and the electric lifting table is directly controlled by the electronic control board to lift to this height, reducing the number of times the user tries to adjust by relying on their own feeling and improving the operation convenience. Compared with the prior art, complex components such as a touch screen and a camera are omitted, the overall size can be reduced, and the cost can be significantly reduced.

[0039] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of non-conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments. Unless otherwise specified, the materials and equipment used in this embodiment can be purchased from the market. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described by referring to the drawings below are exemplary and are only used to explain the present application, and should not be construed as a limitation to the present application.

[0040] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. In the description of the present application, the meaning of "a plurality" is two or more, unless otherwise specifically and precisely defined.

[0041] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "connected", "communicated", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, or it can be connected through an intermediate medium, or it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0042] Embodiment 1: This embodiment provides a hand controller, as shown in Figure 1 , Figure 2 and Figure 3 . The hand controller includes a housing and a control unit disposed inside the housing. The housing includes a mounting base 1 and a first rotating shell 2 rotatably connected to the mounting base 1. The control unit includes an electronic control board 4 fixedly disposed on the mounting base 1, a pressing member 7 for triggering the electronic control board 4, an angle sensor 40 electrically connected to the electronic control board 4, and a display screen 5 electrically connected to the electronic control board 4.

[0043] Among them, the angle sensor 40 is used to detect the rotation angle data of the first rotating shell 2 and transmit the rotation angle data to the electronic control board 4. The display screen 5 is used to display the user height data corresponding to the rotation angle data obtained from the electronic control board 4. The electronic control board 4 is configured to control the electric lifting table to lift to the height corresponding to the user height data after being triggered by the pressing member 7. It should be noted that the corresponding relationship between the rotation angle data and the user height data is preset and can be set as needed. For example, in this embodiment, the change accuracy of the user height data is 1 cm, that is, during the process of rotating the first rotating shell 2, the user height data gradually increases or decreases in increments of 1 cm.

[0044] Through the cooperation of the electronic control board 4, the angle sensor 40 and the display screen 5, the rotation angle data of the first rotating shell 2 can be detected, converted into user height data, and the user height data is displayed on the display screen 5. The user can obtain the user height data input to the electronic control board 4 by rotating the first rotating shell 2 through the display screen 5. After reaching the user's own height data, the pressing member 7 is used to trigger the electronic control board 4, and the electronic control board 4 can control the electric lifting table to lift to the height corresponding to the user height data. That is, by presetting the height value corresponding to the user height data, a reference standard is given to the user, and the electronic control board 4 directly controls the electric lifting table to lift to this height, reducing the number of times the user tries to adjust by relying on their own feeling and improving the operation convenience. Compared with the prior art, complex components such as touch screens and cameras are omitted, which can reduce the overall size and significantly reduce costs.

[0045] The angle sensor 40 in this embodiment can be directly purchased on the market. The angle sensor 40 generally includes a detection element with a shaft hole and a rotating shaft extending into the shaft hole. When the rotating shaft rotates a certain angle (related to the accuracy of the angle sensor 40), the detection element will count, and thus the rotation angle of the rotating shaft can be obtained. During use, the detection element is electrically connected to the electronic control board 4, and the rotating shaft is assembled with the first rotating shell 2. When the first rotating shell 2 is rotated, the rotating shaft will be driven to rotate, and then the rotation angle data of the first rotating shell 2 can be detected by the detection element.

[0046] It is easy to understand that the lifting of the electric lifting table is realized by the lifting of the electric lifting table legs, and the electric lifting table legs rely on the driving mechanism. The driving mechanism can be an electric push rod or the cooperation of a driving motor and a lead screw, etc. The driving mechanism of the electric lifting table legs is prior art and will not be elaborated here. Therefore, the electronic control board 4 needs to be electrically connected to the driving mechanism in the electric lifting table to realize the transmission of control signals. For this purpose, the electronic control board 4 in this embodiment is provided with an electrical connection socket 44, and the mounting seat 1 is provided with a through hole adapted to the electrical connection socket 44, and the electrical connection socket 44 is exposed through the through hole, which facilitates the connection operation of the external cable to the electrical connection socket 44.

[0047] In addition, as Figure 1 shown in Figure 1 , in this embodiment, an installation plate 101 is further formed on the installation base 1. The hand controller can be quickly and conveniently installed on the electric lifting table through the installation plate 101. Generally, the hand controller is installed at the table body of the electric lifting table.

[0048] Combined with Figure 1 and Figure 3 shown in Figure 1 and Figure 3 , the first rotating shell 2 in this embodiment includes a first shell 20 in a cylindrical shape. The outer shell further includes a cover plate 6. The cover plate 6 is arranged at the open end of the first shell 20. The installation base 1, the first shell 20 and the transparent cover plate 6 cooperate to form an installation cavity, and the control unit is arranged in the installation cavity. Thus, except for the aforementioned installation plate 101, the outer contour of the remaining part of the outer shell is generally cylindrical (not a standard cylinder, and there are differences in the diameters at some structural parts), and it is easy to realize a miniaturized design in terms of structure. The projection of the outer shell in this embodiment on a set plane along the axial direction of the first shell 20 is circular. The set plane is perpendicular to the central axis of the first shell 20, and the diameter dimension of the projection is a selected value between 50 mm and 70 mm. That is to say, the outer contour of the part of the outer shell of this hand controller except the installation plate 101 is generally cylindrical (there are slight differences in the outer diameter dimensions of the first shell and the base), and the maximum diameter dimension of the outer contour of the outer shell can be designed to be at least 50 mm at the minimum, which is much smaller than the size of the existing hand controllers.

[0049] Furthermore, combined with Figure 4 and Figure 5 shown in Figure 4 and Figure 5 , the cover plate 6 and the display screen 5 in this embodiment are both fixedly arranged on the pressing member 7. The cover plate 6 has a transparent area corresponding to the position of the display screen 5. The pressing member 7 has a first position and a second position relative to the electronic control board 4. The hand controller further includes an elastic member 73 that presses on the pressing member 7 to make the pressing member 7 tend to slide to the first position. When the pressing member 7 moves from the first position to the second position, it presses on the trigger button 42 of the electronic control board 4 to trigger the electronic control board 4. That is to say, when the user is performing an adjustment operation, after the first rotating shell 2 is rotated in place, pressing the cover plate 6 can press on the pressing member 7, causing the pressing member 7 to move from the first position to the second position, and then pressing the trigger button 42 of the electronic control board 4 to trigger the electronic control board 4.

[0050] It should be noted that in this embodiment, the cover plate 6 is directly made of a transparent plastic material (such as transparent PP material). That is to say, as long as the cover plate 6 has a transparent area corresponding to the position of the display screen 5, the part outside the transparent area can either also be transparent or opaque.

[0051] In this embodiment, the pressing member 7 is slidably disposed in the first housing 20. Correspondingly, the cover plate 6 is in clearance fit with the first housing 20. When the user presses the cover plate 6, the cover plate 6 and the pressing member 7 can be synchronously driven to slide relative to the first housing 20 (i.e., the pressing member 7 moves from the first position to the second position relative to the electronic control board 4), thereby completing the triggering action on the electronic control board 4.

[0052] The pressing member 7 in this embodiment includes a pressing plate 70, a limiting claw 71, and a pressing block 72 for pressing on the trigger button 42. The limiting claw 71 and the pressing block 72 are both formed on the pressing plate 70. A through hole 43 for the limiting claw 71 to pass through is provided on the electronic control board 4. The claw portion of the limiting claw 71 passes through the through hole 43. When the pressing member is in the first position, the claw portion of the limiting claw 71 abuts against the surface of the electronic control board 4 facing the base 10, thereby restricting the moving stroke of the pressing member 7. Under the action of the elastic member 73, the pressing member 7 always maintains a tendency to move towards the first position. By providing a suitable limiting claw 71, the pressing member 7 can be kept at the first position without external force.

[0053] The first rotating shell 2 in this embodiment further includes a connecting plate 21 disposed in the first housing 20. The connecting plate 21 is located between the pressing plate 70 and the electronic control board 4. Correspondingly, the connecting plate 21 is provided with an opening 210 for the limiting claw 71 and the pressing block 72 in the pressing member 7 to pass through. One end of the aforementioned elastic member 73 is fixedly disposed on the pressing plate 70, and the other end abuts against the connecting plate 21. There are two functions of setting the connecting plate 21: on the one hand, under the action of the elastic member 73, when the pressing member 7 is in the first position, the elastic member 73 presses on the connecting plate 21, so that the connecting plate 21 will not fall off from the annular partition 11; on the other hand, the opening 210 on the connecting plate 21 also allows the rotating shaft in the aforementioned angle sensor 40 to pass through. The angle sensor 40 in this embodiment is integrally annular, and its hollow part can allow the limiting claw 71 and the pressing block 72 to pass through. A snap structure is provided between the inner wall of the opening 210 on the connecting plate 21 and the rotating shaft of the angle sensor 40 (as Figure 3 shown in, a card slot 211 can be provided on the connecting plate 21, and a convex block adapted to the card slot 211 can be provided on the rotating shaft accordingly), so that the first rotating shell 2 can drive the rotating shaft in the angle sensor 40 to rotate.

[0054] As described above, the display screen 5 is fixed to the pressing member 7. Specifically, an installation groove 700 is provided on the side of the pressing plate 70 facing the cover plate 6. The display screen 5 is positioned in the installation groove 700. The display screen 5 can be clamped and fixed in the installation groove 700 by an interference fit method, or a connecting member such as a snap member can be provided to position the display screen 5 in the installation groove. A connecting hole 701 is provided on the bottom wall of the installation groove 700. The cable of the display screen 5 passes through the connecting hole 701 and the opening 210 and is electrically connected to the electronic control board 4.

[0055] As Figure 6 and Figure 7 shown, in an alternative embodiment, the display screen 5 only needs to be able to display user height data corresponding to the rotation angle information of the first rotating shell 2. Of course, in order to provide rich information to the user, in this embodiment, the display screen 5 is further configured to be able to display the desktop height information of the current electric lifting table (as Figure 7 shown), and at the same time, it is also able to display the desktop height information recommended according to the user height data (as Figure 6 shown). It is easy to understand that the display interface of the display screen can also be designed as needed to enable it to display other information.

[0056] It is easy to understand that the first rotating shell 2 can perform a 360° circumferential rotation, and it can rotate clockwise or counterclockwise. The angle sensor 40 only needs to detect its rotation angle.

[0057] The hand controller provided in this embodiment can be applied to an electric lifting table. The electric lifting table includes electric lifting table legs, a table body provided on the electric lifting table legs, and the hand controller provided in this embodiment. The electronic control board 4 in the hand controller is electrically connected to the electric lifting table legs and is used to control the lifting of the electric lifting table legs. Generally, the hand controller is fixedly installed on the table body through the mounting plate 101 for easy operation by the user.

[0058] Embodiment 2: This embodiment also provides a hand controller. The difference between this embodiment and the above embodiment is that the hand controller provided in this embodiment adds a second rotating shell and a detection component. Specifically, in combination with Figure 8 , Figure 9 , Figure 10 and Figure 11 shown, the housing of the hand controller further includes a second rotating shell 3 rotatably provided on the mounting seat 1, and the control unit further includes a detection component electrically connected to the electronic control board 4. The detection component is used to detect the position change information of the second rotating shell 3 and transmit the position change information to the electronic control board 4. The electronic control board 4 is further configured to be able to control the lifting of the electric lifting table according to the position change information when the second rotating shell 3 rotates from the initial position to the working position. Through the cooperation of the electronic control board 4 and the detection component, the position change information of the second rotating shell 3 can be detected, and then the electronic control board 4 controls the lifting of the electric lifting table according to the position change information.

[0059] Among them, the position change information refers to the position change information of the second rotating shell 3 after being rotated compared to the initial position, and the rotation direction and rotation angle of the second rotating shell 3 can be obtained through the position change information. Further, through presetting, the clockwise and counterclockwise rotation directions of the second rotating shell 3 can be made to correspond to the lifting action of the electric lifting table. For example, in this embodiment, when the second rotating shell 3 is rotated clockwise, the electric lifting table rises; when the second rotating shell 3 is rotated counterclockwise, the electric lifting table descends.

[0060] It should also be noted that "the electric control board 4 is further configured to be able to control the lifting of the electric lifting table according to the position change information when the second rotating shell 3 rotates from the initial position to the working position" means that the electric lifting table will be controlled to lift only when it is detected that the second rotating shell 3 rotates from the initial position to the working position. On the contrary, when the second rotating shell 3 returns from the working position to the initial position, it will not trigger the electric control board 4 to control the lifting of the electric lifting table. In addition, the electric control board 4 controls the lifting of the electric lifting table according to the position change information. The working position can be designed as a certain specific position, as long as the second rotating shell 3 is rotated to the set angle, the working position will be reached, and then the electric control board 4 will be triggered to control the lifting of the electric lifting table; or the working position can be designed as a section of the rotation stroke of the second rotating shell 3, as long as the second rotation is rotated to be within this section of the stroke, the electric control board 4 can be triggered to control the lifting of the electric lifting table. That is, in an alternative embodiment, the user can rotate the second rotating shell 3 to a specific working position and keep the second rotating shell 3 stationary, and the electric lifting table will perform a lifting action; in another alternative embodiment, during the process of the user rotating the second rotating shell 3, the lifting action of the electric lifting table synchronously follows the rotation action of the second rotating shell 3.

[0061] It is easy to understand that the user can separately and directly use the first rotating shell 2 or the second rotating shell 3 to perform the height adjustment operation of the electric lifting table, or can also use the first rotating shell 2 and the second rotating shell 3 in combination to perform the height adjustment operation of the electric lifting table. For example, first use the first rotating shell 2 to input the user's personal height data, and directly control the electric lifting table to lift to the height value corresponding to the user's height data through the electric control board 4. If the user is not satisfied with the height value corresponding to the user's height data given by the electric control board 4, the electric lifting table can also be controlled to lift by rotating the second rotating shell 3. Since the height value corresponding to the user's height data has been given, generally, the height that the user is satisfied with will be near this height value, and only the second rotating shell 3 needs to be rotated for fine-tuning operations. Thereby improving the convenience of the entire height adjustment operation.

[0062] The detection component in this embodiment includes an induction magnet 41 and a Hall element (not shown in the figure) adapted to the induction magnet 41, such as Figure 10As shown in the figure, in this embodiment, the induction magnet 41 is positioned on the second rotating shell 3. Specifically, positioning posts 31 are provided on the inner wall of the second rotating shell 3. The induction magnet 41 is annular and is sleeved outside the positioning posts 31. The Hall element is fixed to the electronic control board 4 and is electrically connected to the electronic control board 4. When the second rotating shell 3 is rotated, the induction magnet 41 rotates accordingly. The electronic control board 4 is triggered by the magnetic induction signal between the induction magnet 41 and the Hall element to control the lifting of the electric lifting table.

[0063] When designing the arrangement positions of the induction magnet 41 and the Hall element, in an alternative embodiment, when the second rotating shell 3 is in the initial position, no Hall element is provided at the position corresponding to the induction magnet 41 on the electronic control board 4, while when the second rotating shell 3 is in the working position, a Hall element is provided at the position corresponding to the induction magnet 41 on the electronic control board 4. In another alternative embodiment, it is the opposite. When the second rotating shell 3 is in the initial position, a Hall element is provided at the position corresponding to the induction magnet 41 on the electronic control board 4, while when the second rotating shell 3 is in the working position, no Hall element is provided at the position corresponding to the induction magnet 41 on the electronic control board 4. Therefore, the setting position and the number of Hall elements can be selectively arranged according to requirements, which will not be elaborated here.

[0064] In other alternative embodiments, other solutions can also be selected for the detection component. Essentially, the detection component is for detecting the position change of the second rotating shell 3. Therefore, an infrared induction sensor can also be used for detection, and the position change information of the second rotating shell 3 is detected by using the signal transmission change between the transmitting end and the receiving end caused during the rotation of the second rotating shell 3.

[0065] The hand controller further includes an elastic member 8 disposed between the second rotating shell 3 and the mounting base 1. The elastic member 8 presses on the second rotating shell 3 with a tendency for the second rotating shell 3 to move towards the initial position. Specifically, the elastic member 8 in this embodiment is a torsion spring, and the torsion spring is sleeved on a mounting post provided on the mounting base 1. Two limiting blocks 32 are spaced apart on the inner wall of the second rotating shell 3, and the two pins of the torsion spring respectively abut against the limiting blocks 32. In this way, when the second rotating shell 3 is rotated, one of the pins can be driven to act through the limiting blocks 32. When the user cancels the force applied to the second rotating shell 3, the second rotating shell 3 returns to the initial position under the action of the torsion spring.

[0066] As mentioned above, the hand controller in the related art also has problems such as easy accidental touch and large size. For this reason, in this embodiment, the structure of the outer shell is further designed to solve the above problems. Specifically, in combination with Figure 8 、 Figure 10 and Figure 11As shown, the first rotating shell 2 in the hand controller provided in this embodiment includes a first housing 20 in a cylindrical shape, and the second rotating shell 3 includes a second housing 30 in a cylindrical shape. The first housing 20 and the second housing 30 are coaxially arranged. The outer housing further includes a cover plate 6, and the cover plate 6 is arranged at the open end of the first housing 20. The mounting seat 1, the first housing 20, the second housing 30 and the cover plate 6 cooperate to form a mounting cavity, and the control unit is arranged in the mounting cavity.

[0067] Thus, except for the aforementioned mounting plate 101, the outer contour of the remaining part of the outer housing is generally cylindrical (not a standard cylinder, with different diameters at some structural parts), and it is easy to achieve a miniaturized design in terms of structure. In actual manufacturing, except for the aforementioned mounting plate 101, the maximum outer diameter dimension of the outer contour of the remaining generally cylindrical part of the outer housing is a selected value between 50 mm and 70 mm, and the height dimension is a selected value between 10 mm and 30 mm.

[0068] Further, in this embodiment, the dimensions of the first housing 20 and the second housing 30 are also designed. Specifically, the outer diameter of the second housing 30 in this embodiment is larger than that of the first housing 20. The outer diameter of the first housing 20 is set as R, the height dimension is H, the outer diameter of the second housing 30 is r, and the height dimension is h. Among them, R < r, and 3h ≤ H ≤ 5h. In actual manufacturing, the outer diameter of the second housing 30 is slightly larger than that of the first housing 20. For example, the outer diameter of the first housing 20 is designed to be 50 mm, and the outer diameter of the second housing 30 is designed to be 54 mm. The advantage of this design is that the second housing 30 can protrude from the first housing 20 due to the difference in their outer diameters, so there is no need to worry about touching the first housing 2 when rotating the second housing 30. Furthermore, the design height dimension of the second housing 30 can be reduced. The principle is as follows: In an alternative embodiment, the outer diameter of the second housing 30 can be designed to be the same as that of the first housing 20. At this time, since the finger width of the average user is about 10 mm, in order to avoid touching the first rotating shell 2 and driving the first rotating shell 2 to rotate during the process of the user screwing and rotating the second housing 30, the height value of the second housing 30 generally needs to be designed to be at least 8 mm. In this embodiment, since the outer diameter of the second housing 30 is larger than that of the first housing 20 and the second housing 30 protrudes from the first housing 20, when the user rotates the second housing 30, there will be a gap between the operating finger and the first housing 2, so even if the height value of the second housing 30 is reduced, it can prevent the first rotating shell 2 from rotating synchronously. In this embodiment, the height value of the second housing 30 is designed to be 3 mm, and the height value of the first housing 20 is designed to be 10 mm. In other alternative embodiments, the minimum height value of the second housing 30 can be 2 mm, and the minimum height value of the first housing 20 can be 7 mm. Considering structures such as the mounting seat 1, the height dimension of the part of the outer housing excluding the mounting plate 101 can reach at least 10 mm at the minimum, and the size is much smaller than the current hand controllers on the market.

[0069] As described above, both the first rotating shell 2 and the second rotating shell 3 are rotatably arranged on the mounting seat 1. Further design is made on the relative position relationship among the three. Specifically, in combination with Figure 12As shown, the mounting base 1 in this embodiment includes a base 10 and an annular partition 11 fixedly arranged on the base 10. The annular partition 11 is formed with a first annular boss 110, and the base 10 is formed with a second annular boss 100. The first housing 20 is rotatably sleeved outside the first annular boss 110, and the second housing 30 is rotatably sleeved outside the second annular boss 100. Among them, the annular partition 11 is located between the first housing 20 and the second housing 30, and the second housing 30 is located between the base 10 and the annular partition 11. By providing the annular partition 11, the first housing 20 and the second housing 30 can be separated, so that the first housing 20 and the second housing 30 do not directly contact each other. In this way, when the first housing 20 or the second housing 30 is rotated alone, the other one will not be driven to rotate due to friction.

[0070] In this embodiment, four first connecting columns 102 are arranged on the base 10. The inner circle of the annular partition 11 extends to form a connecting portion adapted to the first connecting columns 102, and the annular partition 11 is fixedly installed on the base 10 by screws. In addition, second connecting columns 103 are also arranged on the base 10, and positioning holes adapted to the second connecting columns 103 are arranged on the annular partition 11. The annular partition 11 can be preliminarily positioned by the cooperation of the second connecting columns 103 and the positioning holes. In addition, during assembly, the electronic control board 4 is placed on the connecting portion of the annular partition 11, and openings adapted to the first connecting columns 102 are also correspondingly arranged on the electronic control board 4. The electronic control board 4 and the annular partition 11 can be fixedly installed on the four first connecting columns 102 by screws at the same time.

[0071] Furthermore, the annular partition 11 in this embodiment is made of a light guide material. The hand controller further includes a lamp bead 45 arranged on the electronic control board 4, and the electronic control board 4 is further configured to be able to control the lamp bead 45 to emit light when the first rotating shell 2 or the second rotating shell 3 is rotated. In this way, the user can obtain feedback through the lamp bead 45 during operation.

[0072] Due to the limitation of the annular partition 11, the first rotating shell 2 in this embodiment can only rotate circumferentially and cannot be pressed downward along the axial direction towards the base 10. Therefore, the pressing action on the trigger button 42 on the electronic control board 4 cannot be realized through the first rotating shell 2. In other alternative embodiments, the display screen 5 can also be fixedly installed on the pressing member 7, and at the same time, the pressing member 7 and the cover plate 6 are fixedly arranged on the first housing 20. That is, the first rotating shell 2 is designed to be able to rotate circumferentially and move axially.

[0073] Specifically, as Figure 13 shown, in an alternative embodiment, both the pressing member 7 and the cover plate 6 are fixedly arranged on the first housing 20. At the same time, the annular partition 11 is cancelled and replaced with an annular lining plate 9. That is, the mounting base 1 includes a base 10 and an annular lining plate 9 fixedly arranged on the base 10.

[0074] The annular liner 9 is sleeved outside the first housing 20, so that the first rotating housing 2 can be rotatably arranged on the mounting base 1. At the same time, the annular liner 9 can also separate the first rotating housing 2 from the second rotating housing 3 to prevent direct contact between the two.

[0075] The inner circumferential wall of the annular liner 9 extends inwards to form an annular support platform 90, and there is a gap between the end face of the first housing 20 facing the base 10 and the annular support platform 90. In this way, the first housing 20 can move downward and press on the annular support platform 90, and a reset member 91 is arranged between the two, and the reset member 91 can be used to drive the first rotating housing 2 to move upward and reset. The reset member 91 can be a spring, a metal elastic sheet, etc. In a preferred solution, the reset member 91 is a V-shaped metal elastic sheet. One end of the metal elastic sheet is fixedly arranged on the annular support platform 90, and the other end abuts against the end face of the first housing 20 facing the base 10. In this way, the first housing 20 can rotate circumferentially and also move axially, and after pressing the trigger button 42 on the electronic control board 4, it can also return to its original position under the action of the reset member 91. At the same time, during the rotation of the first rotating housing 2, the frictional force generated by the V-shaped metal elastic sheet on it is very small and will not have a negative impact on the rotation of the first rotating housing 2.

[0076] In addition, a limiting structure (not shown in the figure) is arranged between the annular support platform 90 and the inner wall of the first housing 20. Referring to the limiting structure (limiting claws 71 and perforations 43) between the pressing member 7 and the electronic control board 4 described above, a perforation structure is arranged on the annular support platform 90, and a limiting claw structure passing through the perforation is arranged on the inner wall of the first housing 20. The limiting of the first housing 20 is achieved by the abutment between the claw portion of the limiting claw structure and the surface of the annular support platform 90 facing the base 10. Through the limiting structure, the axial movement stroke of the first housing 20 can be limited to prevent the first housing 20 from disengaging from the annular liner 9.

[0077] In this embodiment, the rotation angle of the second rotating housing 3 is designed to be rotatable 30° clockwise and counterclockwise from the initial position. As Figure 14 、 Figure 15 and Figure 16As shown, in this embodiment, when the second rotating shell 3 rotates counterclockwise from the initial position to the working position, the electric lifting table descends synchronously as the second rotating shell 3 rotates; when the second rotating shell 3 rotates clockwise from the initial position to the working position, the electric lifting table ascends synchronously as the second rotating shell 3 rotates. After the user releases the hand, the second rotating shell 3 returns to the initial position under the action of the elastic member 8, and the electric lifting device stops moving. It is easy to understand that in other alternative embodiments, the rotation angle of the second rotating shell 3 can also be other angles. However, in order to avoid interference between the second rotating shell 3 and the mounting seat 1 during rotation, the angles that the second rotating shell can rotate clockwise and counterclockwise from the initial position should not exceed 60°.

[0078] Finally, it should be noted that the above embodiments are only alternative embodiments of the present invention, and the scope of protection of the present invention cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
