[0027] Generally, there is a certain gap between the knob of the desk lamp and the encoder rotating shaft, so that the knob can be pressed to turn on or off the desk lamp. However, the force exerted by the user when rotating or pressing the knob is not uniform, and the gap between the knob and the encoder rotating shaft makes the knob easily sway left and right or shake up and down during use, affecting the user's operation comfort, and the knob is easily damaged under long-term use or incorrect use.

[0028] The present application is described below in conjunction with the accompanying drawings and with reference to specific embodiments:

[0029] Please refer to Figures 1-3 The knob assembly 10 provided by the embodiments of the present application can be applied to the switch of a lamp or other electrical appliance, can turn on or off the electrical appliance through pressing, and can adjust the power or function of the electrical appliance through rotating. The knob assembly 10 is not easy to shake, has a good feeling of pressing or rotating, and has a good user experience.

[0030] In the embodiments of the present application, the knob assembly 10 comprises a base 100, a knob lower cover 200 and a knob upper cover 300. The base 100 is part of a structural member of an electrical appliance, is used for mounting part of electrical components of the electrical appliance, and carries the knob upper cover 300 and the knob lower cover 200. The base 100 has a circuit board 110, and the circuit board 110 has a trigger 111. By driving or connecting the trigger 111, the electrical appliance can be operated according to the mode in which the circuit board 110 is triggered.

[0031] Please refer to Figure 1 The knob lower cover 200 comprises a first support 210, a second support 220 and an elastic member 230. The elastic member 230 connects the first support 210 and the second support 220, and the second support 220 is arranged on the base 100. The knob upper cover 300 is arranged on the side of the knob lower cover 200 away from the base 100, and the knob upper cover 300 has a trigger column 310 arranged through the first support 210. When the knob upper cover 300 moves close to the base 100 to trigger the trigger 111, the elastic member 230 deforms.

[0032] The knob upper cover 300 is a structural member used for contacting when the knob is pressed. By pressing the knob upper cover 300, the knob upper cover 300 moves close to the base 100 and triggers the trigger 111, so that the circuit board 110 in the base 100 is connected or disconnected, and the electrical appliance is turned on or off. By rotating the knob upper cover 300, the trigger column 310 is rotated to trigger the trigger 111, so that the power or function of the electrical appliance is changed.

[0033] The knob lower cover 200 is a structural member for supporting the knob upper cover 300. The first support member 210 is arranged on the second support member 220 through the elastic member 230, that is, the first support member 210 is movable within the deformation range of the elastic member 230 relative to the second support member 220. The second support member 220 is arranged on the base 100. It can be understood that the second support member 220 maintains contact with the base 100, but the first support member 210 is movable relative to the base 100. Therefore, the knob lower cover 200 can maintain contact with the base 100 during the pressing and rotating of the knob upper cover 300 by the user. On the one hand, the gap between the knob lower cover 200 and the base 100 is small, which can improve the appearance of the knob assembly 10 and prevent impurities from entering the interior of the knob assembly 10. On the other hand, the knob lower cover 200 does not shake up and down or swing left and right, and the user has a good experience in rotating the knob assembly 10. Of course, the elastic member 230 has a slow deformation process, and the elastic member 230 provides a certain damping feeling for the user during the pressing of the knob upper cover 300, which improves the pressing feeling and greatly improves the user experience.

[0034] Please refer to Figure 2 and Figure 3 In some embodiments, the second support member 220 is arranged outside the first support member 210, and the thickness of the first support member 210 is less than that of the second support member 220.

[0035] The first support member 210 is arranged inside the second support member 220, and the thickness of the first support member 210 is less than that of the second support member 220. During the pressing of the knob upper cover 300, the first support member 210 moves relative to the second support member 220 inside the second support member 220. The second support member 220 arranged outside the first support member 210 has more contact points with the base 100 and a more dispersed position, which can improve the stability of the second support member 220, thereby providing a better feeling during the rotation of the knob assembly 10 and improving the user experience.

[0036] Please refer to Figure 2 In some embodiments, the first support member 210 can be a circular plate, and the second support member 220 can be a circular cylinder. The outer diameter of the first support member 210 is less than the inner diameter of the second support member 220 to reserve the installation position of the elastic member 230. Of course, the first support member 210 can be other structures that can move inside the second support member 220, and the second support member 220 can be a rectangular cylinder or other hollow structures.

[0037] The knob upper cover 300 is connected with the first support 210, and the knob upper cover 300 further has a cover plate 320 for being pressed by a user, and a trigger column 310 is arranged on one side of the cover plate 320 and is fixedly connected with the cover plate 320. In some embodiments, the size of the cover plate 320 is relatively large, that is, the orthographic projection of the cover plate 320 on the base 100 at least partially covers the orthographic projection of the second support 220 on the base 100. Therefore, the top of the first support 210 is arranged to protrude compared with the top of the second support 220, so that there is a gap 600 between the knob upper cover 300 and the second support 220. When the user presses the cover plate 320, the cover plate 320 moves and deforms the elastic member 230, and the gap 600 between the knob lower cover 200 and the second support 220 is reduced. After the external force disappears, the elastic member 230 is reset to the initial state under the action of the restoring force and pushes the knob upper cover 300 to reset.

[0038] Of course, in some embodiments, the orthographic projection of the cover plate 320 on the base 100 falls within the orthographic projection of the internal cavity of the second support 220 on the base 100, that is, the size of the cover plate 320 is smaller than the size of the cavity of the second support 220. When the cover plate 320 is pressed by the user, the cover plate 320 can move into the second support 220. At this time, the first support 210 can be arranged at any position in the second support 220, as long as the bottom end of the first support 210 is higher than the bottom end of the second support 220.

[0039] Please refer to Figure 2 In some embodiments, the elastic member 230 is an elastic strip, and a plurality of elastic strips are arranged at intervals around the first support 210.

[0040] The elastic strip is a strip-shaped structure with elasticity. Generally, the second support 220 can be made of plastic or metal, and the strip-shaped plastic or metal has a certain elasticity. Therefore, when the elastic member 230 is a plurality of elastic strips, the same material as the second support 220 can be used to manufacture the elastic strips, so as to reduce the machining process of manufacturing the knob lower cover 200 and improve the integrity of the second support 220.

[0041] Please refer to Figure 2 In some embodiments, the first support 210 and the second support 220 are coaxially arranged, and a plurality of elastic strips are arranged at equal intervals in the gap between the first support 210 and the second support 220, that is, the lengths of the plurality of elastic strips are the same. When the first support 210 moves compared with the second support 220, the plurality of elastic strips can provide elastic forces of similar sizes, and the direction of the resultant force of the plurality of elastic strips will be opposite to the direction in which the knob upper cover 300 moves. When the user presses the knob upper cover 300, the feedback of the force felt by the user will be more balanced, and the hand feeling will be better.

[0042] Please refer to Figure 2In some embodiments, the elastic strip has at least one bending section 231. The elastic strip has the bending section 231 so that the total length of the elastic strip is increased, the rigidity of the elastic strip is decreased, the elastic strip is more easily deformed, and the user can more easily press the knob upper cover 300, improving the operation feeling.

[0043] In some embodiments, the knob lower cover 200 is provided with a first through hole 211, the trigger column 310 is arranged in the first through hole 211, and the knob upper cover 300 is fixedly connected with the knob lower cover 200.

[0044] It can be understood that the knob lower cover 200 has a higher outer wall, and after the knob lower cover 200 is fixedly connected with the knob upper cover 300, rotating the knob lower cover 200 can drive the knob upper cover 300 to synchronously rotate, the structure of the knob lower cover 200 is reasonably utilized, and the way of rotating the knob assembly 10 is more in line with ergonomics. In the case where the second support 220 is arranged outside the first support 210, the first through hole 211 is arranged in the first support 210, and at this time, the trigger column 310 of the knob upper cover 300 will be blocked by the second support 220, which can improve the appearance of the knob assembly 10.

[0045] Please refer to Figure 2 and Figure 3 In some embodiments, the knob upper cover 300 is provided with a first positioning member 330, the knob lower cover 200 is provided with a second positioning member 240, and the first positioning member 330 is fixedly connected with the second positioning member 240. The first positioning member 330 can be a plurality of positioning columns, the second positioning member 240 can be a plurality of positioning holes matched with the positioning columns one by one, and the positioning columns and the positioning holes are connected in a clamping manner, so that the knob upper cover 300 is fixedly connected with the knob lower cover 200. Of course, in some embodiments, the knob upper cover 300 and the knob lower cover 200 can also be fixedly connected by bonding or screwing.

[0046] Please refer to Figure 2 and Figure 3 In some embodiments, the second support 220 is provided with a plurality of bosses 221 near one end of the base 100, and the surface of the boss 221 near the base 100 is an arc surface.

[0047] Considering that the second support 220 is in contact with the base 100, when the knob lower cover 200 is rotated, the bottom end of the second support 220 will produce sliding friction with the surface of the base 100, on the one hand, the force required to rotate the knob lower cover 200 is increased; on the other hand, the base 100 is generally provided with a coating, and after rotating the knob lower cover 200 for many times, the second support 220 is easy to damage the surface of the base 100. Therefore, by providing the boss 221 at the bottom end of the second support 220, the contact area between the second support 220 and the base 100 is reduced, and the surface of the boss 221 close to the base 100 is arc-shaped, the contact area between the boss 221 and the base 100 will be less, and the friction between the second support 220 and the base 100 is reduced, so that the user can rotate the knob lower cover 200 without using too much force, and the use feeling is improved.

[0048] Of course, a plurality of bosses 221 are arranged at the bottom end of the second support 220 at equal intervals around the axis of the second support 220, so as to ensure the stability of the second support 220 on the base 100.

[0049] Please refer to Figure 1 and Figure 3 In some embodiments, the knob assembly 10 further comprises a gasket 400 arranged between the knob lower cover 200 and the base 100. That is, during rotation of the second support 220, the second support 220 is in sliding friction with the gasket 400, which can avoid damage to the base 100. The surface of the gasket 400 is smooth, which can further reduce the friction between the second support 220 and the gasket 400. For example, a POM (polyformaldehyde) gasket 400 can be used to reduce the friction between the second support 220 and the base 100 by using the self-lubricating and wear-resistant properties of POM material.

[0050] Specifically, the gasket 400 can be arranged on the base 100 by screwing, so as to facilitate maintenance and replacement of the gasket 400.

[0051] Of course, in some embodiments, the knob upper cover 300 is rotationally connected with the knob lower cover 200, and the second support 220 of the knob lower cover 200 is fixedly connected with the base, and the knob upper cover 300 can still have a good pressing feeling, as long as the thickness of the knob upper cover 300 is increased, and the area of the side ring wall of the knob upper cover 300 is increased, the user can still have a good feeling when rotating the knob upper cover 300.

[0052] Based on the same inventive concept, the lighting device provided by the embodiment of the present application comprises a light-emitting assembly and a knob assembly 10, the circuit board 110 of the knob assembly 10 is electrically connected with the light-emitting assembly, and the user can turn on or off the light-emitting assembly or adjust the light-emitting assembly by pressing or rotating the knob upper cover 300. It should be noted that the rotating of the knob upper cover 300 can be directly rotating the knob upper cover 300, or rotating the knob lower cover 200 to rotate the knob upper cover 300.

[0053] In some embodiments, the base 100 comprises a base upper cover 120 and a base lower cover 130, and the base upper cover 120 and the base lower cover 130 are connected to have a cavity 140 between the base upper cover 120 and the base lower cover 130 for accommodating the circuit board 110 or other electrical structures. In some embodiments, the base upper cover 120 can further be provided with a groove 121, so that the knob lower cover 200 is arranged in the groove 121, and the knob lower cover 200 is limited by the groove 121, further improving the stability of the knob lower cover 200 during rotation, and improving the use feeling of the knob assembly 10.
