Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a rotary controller and an electric lifting table with the same. Background Art

[0002] Electric lifting tables are commonly used for desks, writing desks, kitchen countertops, etc., and the height of the tabletop can be conveniently adjusted through the electric lifting table. In related technologies, the lifting action of the electric lifting table is generally controlled by a controller, and structures such as mechanical switches, paddles, buttons, touchscreens, and knobs are arranged on the controller to output operation instructions to the electric lifting table. Among them, the knob scheme is widely used due to advantages such as not being prone to dust accumulation, not being prone to accidental triggering, and being convenient for users to operate. The knob is generally an annular shell with or without a cover, which is rotatably installed on the base. A detection component is arranged between the knob and the electronic control board of the controller, and the rotation position change of the knob relative to the base is detected through the detection component. Then, the electronic control board outputs corresponding control signals according to the above rotation position change. Since the knob needs to be rotatably installed on the base, a rotating groove structure is generally arranged on the base in the design of such controllers in related technologies to install the knob, which causes part of the structure of the knob to be blocked in the height direction. In order to facilitate the screwing operation of the user, the size of the knob in the height direction that can contact the user cannot be too small, which results in limitations in the design of the height size of such controllers and makes it difficult to further carry out a thin and light design.

[0027] This embodiment provides a rotary hand controller, which is used for electrically connecting with the electric lifting table legs in an electric lifting table to control the operation of the electric lifting table legs. As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the rotary hand controller includes a base 1, a rotary housing 2 rotatably arranged on the base 1, an annular connecting member 5 fixedly arranged on the base 1, an electronic control board 3 positioned within the inner circle of the annular connecting member 5, and a detection assembly arranged between the rotary housing 2 and the electronic control board 3. The detection assembly is used to detect the change information of the rotation position of the rotary housing 2, and the electronic control board 3 is used to send corresponding control signals to the electric lifting table legs according to the change information of the rotation position.

[0028] The working principles of the electronic control board 3 and the detection assembly are prior art, which are described as follows: The rotary housing 2 has an initial position and a working position relative to the base 1. The working position includes a first working position and a second working position. When the rotary housing 2 in the initial position is rotated clockwise by the user, the rotary housing 2 can be rotated to the first working position. Correspondingly, when the rotary housing 2 in the initial position is rotated counterclockwise by the user, the rotary housing 2 can be rotated to the second working position. The rotation position change information is the position change information of the rotary housing 2 when it rotates from the initial position to the first working position or the second working position. When the detection assembly detects that the rotary housing 2 rotates from the initial position to the first working position, the electronic control board 3 sends a control instruction to the electric lifting table legs, and this control instruction can be preset as an instruction to control the electric lifting table legs to rise. Correspondingly, when the detection assembly detects that the rotary housing 2 rotates from the initial position to the second working position, the electronic control board 3 sends a control instruction to the electric lifting table legs, and this control instruction can be preset as an instruction to control the electric lifting table legs to lower. It is easy to understand that the relationship between the above control instruction and the rotation direction of the rotary housing 2 can be set variably.

[0029] In this embodiment, the rotation angle of the rotary housing 2 is designed to be rotatable 30° clockwise and counterclockwise from the initial position. It is easy to understand that in other optional embodiments, the rotation angle of the rotary housing 2 can also be other angles. However, in order to avoid interference between the rotary housing 2 and the structures arranged on the base 1 during rotation, the angles that the rotary housing 2 can rotate clockwise and counterclockwise from the initial position should not exceed 60°. When the rotary housing 2 stops rotating, the electronic control board 3 sends a control instruction to the electric lifting table legs to stop lifting. At the same time, an elastic member 8 can also be arranged between the rotary housing 2 and the base 1, and the elastic member 8 presses on the rotary housing 2 with a tendency to rotate the rotary housing 2 to the initial position. In this way, when the user rotates the rotary housing 2, the elastic deformation force of the elastic member 8 needs to be overcome. When the user stops operating, the elastic member 8 can drive the rotary housing 2 to return to the initial position. In this embodiment, the elastic member 8 is taken as a torsion spring for illustration. In other optional embodiments, structures such as springs and metal elastic sheets can also be used as the elastic member 8.

[0030] The working principles of the above-mentioned electronic control board 3 and the detection component are prior arts and will not be elaborated here. In addition, the arrangement of the above-mentioned elastic member 8 and the design of the rotation angle of the rotating shell 2 are both prior arts and will not be elaborated here.

[0031] Combined with Figure 5 As shown in, the base 1 in this embodiment includes a bottom plate 10 and an annular protrusion 11 formed on the bottom plate 10. The annular connecting member 5 includes a first annular partition 51 and an annular enclosing plate 50 formed on the first annular partition 51. An annular flange 20 is formed on the lower end surface of the rotating shell 2. The rotating shell 2 is located between the bottom plate 10 and the first annular partition 51. The lower end surface of the rotating shell 2 is in clearance fit with the bottom plate 10, and the inner circumferential wall of the lower end of the rotating shell 2 is in clearance fit with the annular protrusion 11. The inner circumferential wall of the annular flange 20 is in clearance fit with the outer circumferential surface of the bottom plate 10. The upper end surface of the rotating shell 2 is in clearance fit with the first annular partition 51, and the inner circumferential wall of the upper end of the rotating shell 2 is in clearance fit with the annular enclosing plate 50.

[0032] By providing the annular connecting member 5 and improving the structures of the base 1 and the rotating shell 2. Specifically, an annular protrusion 11 is provided on the base 1, and an annular flange 20 is provided on the rotating shell 2. Through the cooperation of the structures provided on the base 1, the rotating shell 2 and the annular connecting member 5, while realizing the rotational installation of the rotating shell 2 relative to the base 1, the outer circumferential surface of the rotating shell 2 can be completely exposed. That is, the entire outer circumferential surface of the rotating shell 2 is available for the user to contact and perform screwing operations. In this way, the height dimension of the rotating shell 2 can be designed as the minimum height dimension required for the user's screwing operation, thereby facilitating the overall thin and light design of the rotary hand controller. By comparison, the thickness dimension (the height dimension of the rotary hand controller in the up and down direction) of the rotary hand controller provided in this embodiment can be reduced by about 10% compared with the prior art rotary hand controllers of this type.

[0033] It should be noted that the up and down directions in the above-mentioned "upper end surface" and "lower end surface" in this embodiment are based on Figure 4 the placement form of the rotary hand controller shown in, that is, the side where the base 1 is located in the rotary hand controller is set as the lower side, and the side where the electronic control board 3 is located is set as the upper side.

[0034] Furthermore, an annular step 21 is formed on the inner circumferential wall of the rotating shell 2 in this embodiment. The annular connecting member 5 further includes a second annular partition 52 formed on the annular enclosing plate 50. The second annular partition 52 is parallel to the first annular partition 51 and the two are respectively located at the bottom end and the top end of the annular enclosing plate 50. The second annular partition 52 is in clearance fit with the annular step 21. Through the above structural design, the rotational stability of the rotating shell 2 relative to the base 1 can be further enhanced.

[0035] Combined with Figure 4and Figure 5 As shown in Figure 5 , the rotary hand controller forms a cavity through the cooperation of a bottom plate 10, a rotary housing 2, an annular connecting member 5, and an electronic control board 3. The aforementioned detection assembly and elastic member 8 are both arranged in the cavity. To facilitate the installation of the annular connecting member 5 and the electronic control board 3 on the base 1, the base 1 in this embodiment further includes a connecting post 12 formed on the bottom plate 10, and the annular connecting member 5 further includes a connecting arm 53 formed on the annular surrounding plate 50. The connecting post 12 and the connecting arm 53 are both located in the aforementioned cavity. Among them, the connecting post 12 is provided with a threaded hole, and the connecting arm 53 is provided with a connecting hole 530. The base 1 and the annular connecting member 5 are fixedly connected to the base 1 through a locking screw (not shown in the figure) passing through the connecting hole 530 and locked in the threaded hole. Further, the electronic control board 3 in this embodiment is placed on the connecting arm 53. The electronic control board 3 is provided with a mounting hole 30, and the locking screw passes through the mounting hole 30 and locks the electronic control board 3 to the annular connecting member 5.

[0036] To facilitate the assembly operation, a positioning post 13 is further provided on the bottom plate 10 in this embodiment, and the connecting arm 53 is further provided with a positioning hole 531 adapted to the positioning post 13. The positioning post 13 is inserted into the positioning hole 531. In this way, during assembly, the annular connecting member 5 can be accurately installed on the base 1 by aligning the positioning hole 531 with the positioning post 13 and inserting it.

[0037] To facilitate the user to obtain relevant information, the rotary hand controller provided in this embodiment further includes a cover plate 6 fixedly arranged on the inner ring of the annular connecting member 5 and a display screen 7 arranged on the cover plate 6. The cover plate 6 is located above the electronic control board 3, and the display screen 7 is electrically connected to the electronic control board 3. By providing the cover plate 6, the electronic control board 3 can be shielded to prevent dust or light from reducing the service life of the electronic control board 3. At the same time, the provided display screen 7 can be used to display relevant information. For example, the electronic control board 3 can display the desktop height information, desktop height change information, etc. of the electric lifting table to the user through the display screen 7.

[0038] An indicator light 32 is further provided on the electronic control board 3 in this embodiment. The indicator light 32 is configured to emit light when the rotary housing 2 is rotated. In this way, when the user rotates the rotary housing 2, the user can clearly know that the operation is effective through the emission of the indicator light 32. It is easy to understand that when this design is adopted, the annular connecting member 5 can be made of a transparent material.

[0039] The detection assembly in this embodiment includes an induction magnet 4 and a plurality of Hall sensors (not shown in the figure) evenly distributed in the circumferential direction, as Figure 2As shown, the induction magnet 4 is fixedly installed on the inner circumferential wall of the rotating shell 2, and the Hall sensor is positioned on the surface of the electronic control board 3 facing the bottom plate 10. In other alternative embodiments, the induction magnet 4 can also be fixedly installed on the surface of the electronic control board 3 facing the bottom plate 10, and correspondingly, the Hall sensor is positioned on the inner circumferential wall of the rotating shell 2. When the rotating shell 2 is rotated by the user, the induction magnet 4 will rotate with the rotating shell 2. The induction magnet 4 can interact with the Hall sensors at different positions, and thus can detect the change information of the rotation position of the rotating shell 2.

[0040] To facilitate the electrical connection between the electronic control board 3 in the rotary hand controller and external components, in this embodiment, a wire passing hole 100 is further provided on the bottom plate 10, and an electrical socket 31 is provided on the electronic control board 3.
