Detailed Description

The following detailed description and technical contents of the present application are described with reference to the drawings, which are provided for reference and illustration purposes only and are not intended to limit the present application.

The present application provides an LED display type rotary push switch, as shown in fig. 1 to 3, which can display information after rotary pushing, such as information of adjusted volume, temperature, or fire of a heating stove. The LED display type rotary push switch (hereinafter referred to as a rotary push switch) of the present application includes a switch main body 100, and in one embodiment, may further include a housing 800, where the housing 800 covers the switch main body 100.

As shown in fig. 1 to 6, the switch main body 100 includes: the fixing base 1, the actuating member 2, the light emitting module 3 and the light shielding member 4 may further include a light-transmitting printing sheet 5 in one embodiment.

The fixing base 1, which is a stationary member in the present application, has a receiving portion 11, and in one embodiment, at least one setting portion 12, and an elastic member 13 disposed in the at least one setting portion 12. The number of the installation portions 12 may be one, or two or more (including the number), and in the present embodiment, a plurality (at least three) of the installation portions 12 are exemplified, and the installation portions 12 surround each other. The elastic component 13 may be a single-piece structure or a multi-piece structure and includes more than two elastic support sets (not labeled with reference numerals), in this embodiment, a plurality of elastic support sets corresponding to the number of the setting portions 12 are exemplified, and each elastic support set is disposed in each setting portion 12.

The elastic support sets can be any member having an elastic support function, in an embodiment, each elastic support set includes an elastic element 131 and a ball 132, one end of the elastic element 131 abuts against the inside of the setting portion 12, and the ball 132 is supported by the other end of the elastic element 131 and partially protrudes out of the setting portion 12 as shown in fig. 6.

The light emitting module 3 is disposed in the accommodating portion 11. The light emitting module 3 includes a circuit board 31, a plurality of LED elements 32, a button 33, and a sensing element 34. The button 33, the sensing element 34 and each LED element 32 are electrically disposed on the circuit board 31. The LED element 32 is a Light-emitting diode (LED) Light-emitting element; the button 33 may be any member that can be turned on by pressing; the sensing device 34 can be any device having a sensing function, and in the present embodiment, a light-shielding sensing device is taken as an example for description, and a U-shaped notch of the sensing device 34 seen in fig. 4 is a sensing area of the sensing device.

The actuator 2 is a movable member in the present application, and is movably covered on the fixing base 1 corresponding to the position of the accommodating portion 11, so that the actuator 2 can perform movements such as rotation and longitudinal translation relative to the fixing base 1. As shown in fig. 5 and 6, the actuator 2 has a concave-convex structure 25, and the actuator 2 is pressed against the balls 132 of each elastic support set by the concave-convex structure 25, so that each elastic support set is elastically supported between the actuator 2 and each setting portion 12, thereby generating a hand feeling of a paragraph when a user rotates the actuator 2 for adjustment.

Actuator 2 has a first annular wall 21, a second annular wall 22 and a hollow portion 23, in one embodiment, first annular wall 21 and second annular wall 22 are coaxially surrounded by hollow portion 23. Wherein, the first annular wall 21 corresponds to the button 33; the second annular wall 22 corresponds to the sensing region of the sensing element 34, and the second annular wall 22 has a plurality of sensing portions 221 as shown in fig. 5. In an embodiment, the second annular wall 22 further has a plurality of non-sensing portions 222, and each sensing portion 221 (for example, a convex tooth) and each non-sensing portion 222 (for example, a gap) are disposed in a staggered manner.

The light-shielding member 4 is correspondingly disposed in the hollow portion 23, so that the light-shielding member 4 simultaneously extends into the accommodating portion 11. The light shielding member 4 may be a member made of a light shielding material and provided with a plurality of light channels 43 as shown in fig. 6, each light channel 43 corresponds to each LED element 32, so that light irradiated by each LED element 32 can only pass through the light shielding member 4 via the light channel 43 and cannot pass through the light shielding member 4 via a portion other than the light channel 43.

It should be noted that, as shown in fig. 4 and fig. 6, the light shielding member 4 has a light exit surface 42, each light channel 43 penetrates the light exit surface 42 to form a first light exit hole (not labeled with a reference numeral) on the light exit surface 42, and the first light exit holes are assembled on the light exit surface 42 to form at least one information symbol S for the information (for example, displaying the adjusted volume, temperature or the fire power of the heating stove). In one embodiment, the information symbol S may be a seven-segment number (composed of seven first light-emitting holes) as shown in fig. 4, and there are three information symbols S side by side in fig. 4. In an embodiment, the light shielding member 4 further has a light incident surface 41, the light incident surface 41 and the light emitting surface 42 are opposite to each other, each light channel 43 penetrates between the light incident surface 41 and the light emitting surface 42, and the light rays irradiated by each LED element 32 are incident into each light channel 43 from the light incident surface 41 and finally emitted from the light emitting surface 42.

Therefore, when a user presses the actuating member 2, the actuating member 2 will longitudinally translate relative to the fixing base 1, so as to press the elastic component 13 to elastically contract through the longitudinal translation and press the button 33 to conduct through the first annular wall 21; when the user rotates the actuating member 2, the actuating member 2 will rotate relative to the fixing base 1, so that the sensing portion 221 of the second annular wall 22 passes through the sensing area of the sensing element 34 to sense how much the actuating member 2 rotates relative to the fixing base 1; after the user presses or/and rotates the actuator 2, the corresponding LED device 32 will be conducted, so that the light emitted from the LED device 32 is emitted through the corresponding light channel 43 to form the information on the light-emitting surface 42. In other words, the information is displayed by the LED display (not marked with element symbols) composed of the light-emitting module 3 and the shading member 4, that is, the information can be assembled by at least one information symbol S, so that the cost is greatly reduced, and the market competitiveness is further improved.

In other embodiments not shown in the drawings, the elastic component 13 may also be a single-piece structure, the setting portion 12 is provided as one, the elastic component 13 is disposed in only one setting portion 12, and the elastic component 13 is elastically supported between the actuator 2 and the setting portion 12. Furthermore, the elastic member 13 can be replaced by the elastic button 33, so that the elastic button 33 can elastically support between the first annular wall 21 of the actuator 2 and the circuit board 31, and in this case, the fixing base 1 does not have the installation portion 12.

In an embodiment, as shown in fig. 2 to 6, the LED display may further include a light emitting module 3, a light shielding member 4 and a light transmissive printing sheet 5, wherein the light transmissive printing sheet 5 is attached to the light emitting surface 42. The light-transmitting printed sheet 5 is a light-transmitting sheet body for printing on which a plurality of printed patterns P (a battery pattern, a fire pattern, a clock pattern, etc.) as shown in fig. 2 can be printed. One part of the optical channel 43 forms the first light-emitting hole on the light-emitting surface 42, and the other part forms a plurality of second light-emitting holes 431 on the light-emitting surface 42 as shown in fig. 4, wherein each second light-emitting hole 431 corresponds to each printed pattern P. In this way, the light emitted from the LED element 32 can be emitted through the corresponding light channel 43, the corresponding second light-emitting hole 431 and the corresponding printed pattern P, so that only the corresponding printed pattern P on the light-emitting surface 42 is bright, and the other parts are dark, thereby displaying the aforementioned information. Certainly, another printing image and text (seven-segment hollow printing numbers, no element symbol is marked) as shown in fig. 2 can be further printed on the light-transmitting printing sheet 5, so that when the information is displayed by numbers, the light irradiated by the LED element 32 is emitted through the corresponding light channel 43, the corresponding first light-emitting hole and the corresponding another printing image and text (seven-segment hollow printing numbers), and therefore, only the corresponding another printing image and text (seven-segment hollow printing numbers) on the light-emitting surface 42 is bright, and the other parts are dark.

It should be noted that the actuator 2 may be a wear-resistant actuator, and in one embodiment, may also have a lubricating function, so that even if the first annular wall 21 and the button 33 or the concave-convex structure 25 and the balls 132 are frequently rubbed by a user through normal pressure rotation of the actuator 2, the wear can be greatly reduced, and smooth rotation of the actuator 2 can be ensured due to the lubricating function.

The housing 800 is movably sleeved on the switch main body 100. As shown in fig. 1 to 3 and 6, the housing 800 includes a front case 81 and a rear case 83. The front case 81 covers the switch body 100, the rear case 83 seals the switch body 100 in the case 800, and the front case 81 and the rear case 83 are snap-fixed to each other. The front housing 81 may be of a one-piece structure (not shown) or a two-piece structure as shown and includes a first front housing 811 and a second front housing 812 combined with each other. It should be noted that the front housing 81 and the actuator 2 interfere with each other, and a user can rotate the housing 800 to drive the actuator 2 to rotate synchronously; in one embodiment, the actuating member 2 is protruded with at least two protruding keys 24, the second front shell 812 is correspondingly opened with at least two concave holes 8121, and the protruding keys 24 are correspondingly inserted into the concave holes 8121 to interfere with each other.

In order to provide the function of preventing the erroneous touch, as shown in fig. 7 and fig. 4 to 6, the light emitting module 3 further includes a first processing unit 35 and a second processing unit 36 having a timing function, and the first processing unit 35 and the second processing unit 36 are both electrically connected to the circuit board 31 (which is electrically connected to the circuit board). The first processing unit 35, the second processing unit 36 and the electric device 900 are connected in series, and the button 33 and the sensing element 34 are connected in parallel to the first processing unit 35.

As shown in fig. 7, when the button 33 is pressed to be turned on, the first processing unit 35 will output a first on signal E1 to the second processing unit 36; when the sensing element 34 senses that a predetermined number of the sensing portions 221 pass through the sensing region, the first processing unit 35 outputs a second turn-on signal E2 to the second processing unit 36; when the second processing unit 36 receives the first conducting signal E1 and the second conducting signal E2, the timing of the preset number of seconds will be started, and after the timing of the preset number of seconds is completed, the second processing unit 36 will output the start signal T to the electric device 900 to start the electric device 900.

In short, the user must press (press and rotate) the actuator 2 to rotate a predetermined angle (i.e. the sensing element 34 senses that a predetermined number of sensing portions 221 pass through the sensing area), and then stay in the pressed state for a predetermined time (i.e. the predetermined number of seconds), the second processing unit 36 will output the start signal T, and if these steps are not performed, the start signal T will not be output, so that the touch-preventing function is provided.

In summary, the LED display type rotary push switch of the present application can achieve the intended purpose of use, and solve the disadvantages of the prior art, and completely meet the requirements of the new patent application.

The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all equivalent structural changes made by using the contents of the specification and drawings are included in the scope of the present application, and are fully apparent.
