Description

Technical Field

[0001] This utility model belongs to the field of lighting switch technology, specifically relating to a rotary switch and an assembly having the rotary switch. Background Technology

[0002] Existing rotary switches with pressing and rotating functions, such as the structure disclosed in Chinese Utility Model Patent Application No. 201922374751.0, "Multifunctional Vehicle Light Control Knob" (Authorization Announcement No. CN211335737U), include a rotating housing, a fixed housing, a spring, a pressing block, and a movable rod. The rotating housing is fitted onto the fixed housing. One end of the movable rod extends from the fixed housing, and the other end is connected to the bottom of the pressing block. The spring is fitted onto the movable rod, with one end connected to the pressing block and the other end connected to the fixed housing. This patent allows the pressing block to drive the movement of the movable rod, thereby triggering the switching between high beam and low beam headlights. It also allows the rotation of the rotating housing to adjust the brightness of the headlights.

[0003] The aforementioned knobs require pressing the pressing block and rotating the housing separately for operation, which is inconvenient. To address this, Chinese Utility Model Patent Application No. 202322410285.3, entitled "A Rotary Press Trigger Device and a Knob Control System" (Authorization Announcement No. CN220710180U), discloses a rotary press trigger device, comprising: a rotation detection unit for detecting rotation input; a pressing detection unit for detecting pressing input; a pressing unit that can be pressed to directly or indirectly trigger the pressing detection unit; a rotating unit connected to the rotation detection unit via a connecting part, and driving the rotation detection unit to rotate via the connecting part; and a reset unit that provides a reset force, connected between the connecting part and the pressing part, so that when the rotating part rotates, the pressing part, the reset part, and the connecting part rotate simultaneously.

[0004] During the user's operation of the rotating part, the pressing part, the reset part, and the connecting part rotate simultaneously. Due to the presence of the reset part, it is difficult for the pressing part, the reset part, and the connecting part to maintain a relatively stationary state, resulting in wobbling during rotation and affecting the operating feel. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a rotary switch with stable structure and improved operating feel, in light of the current state of the technology.

[0006] The second technical problem to be solved by this utility model is to provide an assembly having the above-mentioned rotary switch.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a rotary switch, comprising:

[0008] A base on which a first switch and a second switch are mounted;

[0009] A rotating body having an annular wall arranged around a first axis at its center;

[0010] Its characteristic is that it also includes:

[0011] A movable body is disposed on one side of the base in a manner that allows it to move back and forth along the first axis. When the movable body moves close to the base, it is arranged to trigger a first switch on the base. Simultaneously, the movable body is disposed within the inner circumference of the annular wall, and a bearing is provided between the two to constrain them together axially and allow them to rotate relative to each other circumferentially. This allows the annular wall to rotate circumferentially relative to the movable body under the drive of a circumferential external force, thereby triggering a second switch on the base, and to drive the movable body to move under the drive of an axial external force.

[0012] An elastic element acts on the moving body to ensure that the moving body always tends to move away from the base along with the ring wall.

[0013] This invention allows for the activation of either the first or second switch by pressing or rotating the rotating body, making operation convenient. Simultaneously, when the rotating body is rotated, the moving body and elastic element do not rotate with it, effectively preventing wobbling during rotation. Furthermore, the bearing located between the rotating body and the moving body ensures smooth rotation, enhancing the user's control experience.

[0014] Preferably, the moving body includes connected:

[0015] The main body has an annular side peripheral surface for constraining the rotating body on its outer periphery;

[0016] At least two connecting posts are arranged at intervals around the first axis and extend along the extension direction of the first axis. The first end of each connecting post is connected to the main body, and the second end of each connecting post is inserted into a through hole in the base. The design of at least two connecting posts allows the movable body to move back and forth along the first axis on one side of the base, while preventing the connecting posts from rotating circumferentially with the rotating body.

[0017] The aforementioned elastic element can be an existing spring, sheet spring, etc. Preferably, the elastic element is a spring, and the number of springs matches the number of connecting posts, with each spring respectively fitted around the outer periphery of its corresponding connecting post.

[0018] In the above embodiments, preferably, the annular wall of the rotating body is provided with a toothed ring arranged circumferentially and capable of rotating with the rotating body. The second switch is located on the rotation path of each tooth of the toothed ring and is arranged so that it can be swept by each tooth in turn as the toothed ring rotates, thereby recording the sweeping direction and / or number of times the teeth sweep across the second switch. By controlling the direction and / or number of times the teeth sweep across the second switch, the brightness, color temperature, etc. of the lamp can be controlled, realizing the function of rotating to control the light (such as dimming).

[0019] Preferably, the gear ring and the bearing are arranged at intervals along the extension direction of the first axis, with the gear ring relatively close to the base and the bearing relatively far away from the base.

[0020] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: an assembly having a rotary switch as described above, characterized in that: it further includes a base having an open mounting cavity, the base being detachably disposed in the mounting cavity through the open.

[0021] Furthermore, the base and the mounting cavity are respectively provided with matching buckles and locking holes so that the base can be engaged in the mounting cavity.

[0022] Furthermore, it also includes a mask that is detachably mounted over the base, and the mask has a through hole corresponding to the opening position so that the rotating body can pass through and be exposed outside the mask.

[0023] Preferably, there are at least two mounting cavities arranged side by side;

[0024] Each mounting cavity is provided with the aforementioned base, or at least one of the mounting cavities is provided with a detachable socket with a plug hole.

[0025] The cavity can be fitted with knobs, switches, and sockets as needed to meet the different needs of different users.

[0026] Compared with the prior art, the advantages of this utility model are as follows: the first switch or the second switch can be triggered by pressing or rotating the rotating body, which is convenient to operate; at the same time, when rotating the rotating body, the moving body and the elastic element will not rotate with the rotating body, thus effectively avoiding the shaking of the rotating body during rotation; and the bearing located between the rotating body and the moving body can ensure the smooth rotation of the rotating body, improving the user's operating experience.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1-6 The diagram shows a preferred embodiment of a rotary switch and an assembly having the rotary switch according to the present invention. The rotary switch includes a base 1, a rotating body 2, a moving body 3, a bearing 4, an elastic element 5, and a toothed ring 6.

[0035] The base 1 is equipped with a first switch and a second switch 12.

[0036] The rotating body 2 has an annular wall 22 arranged around a first axis 21 at its center, with the first end of the annular wall 21 closed by an end plate and the second end open.

[0037] The movable body 3 is disposed on one side of the base 1 in a manner that allows it to move back and forth along the first axis 21. When the movable body 3 moves close to the base 1, it is arranged to trigger the first switch on the base 1 (the first switch is prior art and will not be described in detail here). At the same time, the movable body 3 is disposed at the second end of the annular wall 22 within the inner circumference of the annular wall 22. A bearing 4 is provided between the two (the bearing is disposed relative to the first end of the annular wall 22) so that the two are axially constrained together and can rotate relative to each other in the circumferential direction. Thus, the annular wall 22 can rotate relative to the movable body 3 in the circumferential direction under the drive of the circumferential external force, thereby triggering the second switch 12 on the base 1. Under the drive of the axial external force, it can drive the movable body 3 to move.

[0038] In this embodiment, the movable body 3 includes a connected main body 31 and four connecting posts 32. The main body 31 has an annular side surface arranged around the first axis 21 to constrain the rotating body 2 to its outer periphery. The four connecting posts 32 are arranged at intervals around the first axis 21 and extend along the extension direction of the first axis 21. The first end of each connecting post 32 is connected to the main body 31, and the second end of each connecting post 32 is respectively inserted into the corresponding through hole 10 on the base 1. This allows the movable body 3 to be movably disposed on one side of the base 1 along the first axis without rotating with the rotating body 2.

[0039] The aforementioned elastic element 5 is a spring. The number of springs matches the number of connecting posts 32. Each spring is respectively sleeved on the outer periphery of its corresponding connecting post 32 and acts on the main body 31 of the moving body 3 so that the moving body 3 always has the tendency to move away from the base 1 along with the annular wall 22.

[0040] The second end of the aforementioned annular wall 21 is provided with a circumferentially arranged gear ring 6 (the gear ring 6 is arranged coaxially with the annular wall 21) that can rotate with the rotating body 2. The second switch 12 is located on the rotation path of each tooth 60 of the gear ring 6 and is arranged so that it can be swept by each tooth 60 in sequence as the gear ring 6 rotates to record the sweeping direction and / or number of times the tooth 60 is swept. At the same time, the gear ring 6 and the bearing 4 are arranged at intervals along the extension direction of the first axis 21, with the gear ring 6 relatively closer to the base 1 and the bearing 4 relatively farther away from the base 1.

[0041] In use, the user can adjust the brightness and color temperature of the lamp by rotating the rotating body 2 clockwise or counterclockwise and controlling the rotation angle, thus achieving the function of rotating to control the light. Furthermore, the method of adjusting the brightness and color temperature of the lamp by recording the sweep direction and / or number of passes of the teeth 60 in this embodiment is existing technology and will not be elaborated upon here. Simultaneously, the lamp can be turned on and off by pressing the rotating body 2 to move the moving body 3.

[0042] like Figure 5 , 6 As shown, the assembly in this embodiment includes a base 7, a face mask 8, a socket 9, and the aforementioned rotary switch.

[0043] The base 7 has two mounting cavities 70 arranged side by side, one on the left and one on the right, with openings on the front. The base 1 of the rotary switch is detachably mounted in one of the mounting cavities 70 through the opening, and the socket 9 with the insertion hole is detachably mounted in the other mounting cavity 70 through the opening. The assembly structure between the socket and the mounting cavity 70 is the same as the assembly structure between the base 1 and the mounting cavity 70. This embodiment will be described using the assembly structure between the base 1 and the mounting cavity 70 as an example. Specifically, the upper and lower surfaces of the base 1 are provided with buckles 13, and the top and bottom walls of the mounting cavity 70 are provided with matching locking holes 71 so that the base 1 can be engaged in the mounting cavity 70.

[0044] The mask 8 is detachably mounted on the base 7, and each of the mask 8 has a through hole 80 corresponding to the opening of each mounting cavity 70. The rotating body 2 passes through the corresponding through hole 80 and is exposed outside the mask.

[0045] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
