Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, specifically to a button structure and a camera device. Background Technology

[0002] In existing button structures, the buttons that users touch and the switches electrically connected to the circuit board must be on the same straight line. When a user presses a button, the trajectory of the press must remain consistent with the straight line containing the button and switch; that is, the pressing direction is fixed in the positive direction. This results in extremely low flexibility in the layout of other internal components in various electronic devices or products containing the switch. In addition, due to the limitations of internal component layout, it is often necessary to design a separate button circuit board instead of directly integrating the switch onto the motherboard. However, a separate button circuit board needs to be connected to the motherboard via ribbon cables and other components, which increases hardware costs and complicates the overall structure.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0020] This embodiment relates to a button structure, see reference. Figures 1-4 The system includes a housing 100, a button lever 200, and a switch 300. The button lever 200 is movably mounted on the housing 100, and the switch 300 is mounted inside the housing 100. The button lever 200 has a first end 221 and a second end 222 opposite to the first end 221; the second end 222 is opposite to the switch 300. The button lever 200 includes an elastic shaft 210 located between the first end 221 and the second end 222. When the first end 221 is pressed, the elastic shaft 210 rotates and one side abuts against the inner wall of the housing 100, and the second end 222 moves towards the switch 300 to trigger the switch 300. When the first end 221 is released, the second end 222 resets under the elastic reset action of the elastic shaft 210, and the switch 300 is in an untriggered state. Compared to traditional button structures that require the pressing trajectory to align with the straight line between the button and switch 300, this button structure is simple in overall design. Furthermore, its installation location on various electronic devices or products (e.g., security cameras) is not limited by the position of switch 300, offering flexibility in installation. This enhances the flexibility of the layout of other internal components within the device, reducing the hardware costs associated with traditional button structures, such as wiring, and adapting to a wider range of layout designs. Additionally, during the reset process of the button lever 200, the elastic potential energy is released via the elastic pivot 210 within the lever 200, eliminating the need for an additional elastic reset component, thus reducing the number of parts and lowering costs.

[0021] Furthermore, referring to Figures 1-4 The button lever 200 also includes: a lever body 220 having a first end 221 and a second end 222, a button portion 230, and a trigger portion 240 for triggering the switch 300. The lever body 220 is located inside the housing 100, an elastic shaft 210 is mounted on the lever body 220, the button portion 230 is mounted on the first end 221 with one side exposed outside the housing 100, and the trigger portion 240 is mounted on the second end 222 and located below the switch 300. Specifically, the elastic shaft 210 is rotatably mounted inside the housing 100, and the switch 300 is positioned directly above the trigger portion 240. When the user presses the button portion 230, the first end 221 of the lever body 220 is pressed down, the elastic shaft 210 rotates and one side abuts against the inner wall of the housing 100, and the second end 222 of the lever body 220 tilts upwards towards the switch 300. The trigger portion 240 then triggers the switch 300, thus activating the circuit in the electronic device or product. When the user releases the button 230, the button 230 is not under pressure, that is, the first end 221 of the lever 220 is not under pressure. The elastic shaft 210 abuts against one side of the inner wall of the housing 100 and releases elastic potential energy, causing the lever 220 to rotate in the opposite direction. At this time, the first end 221 of the lever 220 is raised, and the second end 222 is reset, causing the trigger part 240 to be reset to disconnect the press on the switch 300. The switch 300 is reset to an untriggered state, realizing the disconnection of the circuit in the electronic device or product.

[0022] In this embodiment, the rod body 220, the elastic rotating shaft 210, the button part 230 and the trigger part 240 are integrated into one piece, which reduces the complexity of assembly, increases the smoothness of triggering or disconnecting the switch 300, and makes the reset more sensitive and smooth.

[0023] Furthermore, the button lever 200 is made of soft rubber. In this embodiment, the button lever 200 is made of plastic, that is, the elastic pivot 210 is also made of plastic, and the elastic pivot 210 uses its own elastic wall to achieve reset. In some embodiments, the button lever 200 may also be made of silicone.

[0024] Furthermore, referring to Figures 2-3 as well as Figures 5-6The housing 100 includes a first outer shell 110 and a second outer shell 120. One side of the first outer shell 110 is located below the button lever 200. At least two first protrusions 111 are provided on the lower side of the first outer shell 110 corresponding to both ends of the elastic rotating shaft 210, with adjacent first protrusions 111 spaced apart. Each first protrusion 111 has a first groove 1111 for rotatably assembling the elastic rotating shaft 210. At least two second protrusions 121 are provided on the upper side of the second outer shell 120 corresponding to both ends of the elastic rotating shaft 210, with adjacent second protrusions 121 spaced apart. Each second protrusion 121 has a second groove 1211 corresponding to the first groove 1111. The two ends of the elastic rotating shaft 210 are rotatably assembled between the first groove 1111 and the second groove 1211. The surfaces of the first groove 1111 and the second groove 1211 that abut against the elastic rotating shaft 210 are respectively designated as a first arcuate surface 1111a and a second arcuate surface 1211a. Specifically, the two ends of the elastic shaft 210 extend to the left and right sides of the rod 220, respectively. Two adjacent first protrusions 111 are spaced apart, and two adjacent second protrusions 121 are spaced apart, to ensure that the first and second protrusions 111 and 121 do not affect the rotation of the rod 220 when the ends of the elastic shaft 210 rotate. The arrangement of the first arc-shaped surface 1111a and the second arc-shaped surface 1211a ensures the smoothness of the rotation of the elastic shaft 210. Furthermore, the surface on the inner wall of the second outer shell 120, located between two adjacent second protrusions 121 and abutting against the middle of the elastic shaft 210, is configured as a third arc-shaped surface 124 to ensure that the elastic shaft 210 can smoothly rotate and reset.

[0025] Furthermore, referring to Figure 4Multiple button levers 200 are provided; the button structure also includes: a connector 410 and a support bar 420 with one end fixedly connected to the connector 410; multiple sets of support bars 420 are provided, and the multiple sets of support bars 420 are spaced apart along the length direction of the connector 410; each set includes two support bars 420 spaced apart, and a clearance space 430 is provided between the two support bars 420 in each set for the movement of the lever 220, the elastic rotating shaft 210 and the trigger part 240; the ends of the two support bars 420 in each set away from the connector 410 are respectively fixedly connected to the two ends of the button part 230. Specifically, multiple switches 300 are also provided. The connector 410 and multiple sets of support bars 420 are integrated into one piece. The ends of two support bars 420 in each set, furthest from the connector 410, are fixedly connected to both ends of the button section 230. This achieves a fixed arrangement of multiple button levers 200, multiple sets of support bars 420, and the connector 410, reducing assembly difficulty and complexity when multiple button levers 200 are needed to perform different functions. Furthermore, the multiple sets of support bars 420 are spaced apart along the length of the connector 410, preventing the triggering parts 240 of other button levers 200 from being triggered when one button lever 200 is pressed. In this embodiment, there are three button levers 200, three corresponding switches 300, three sets of support bars 420, six corresponding first protrusions 111, and six corresponding second protrusions 121. When this button structure is assembled into an electronic device or product, the three button levers 200 trigger different functions. For example, when this button structure is assembled into a camera, the three button levers 200 respectively trigger the video call switch 300, the intercom switch 300, and the video hang-up switch 300. In some embodiments, there may be four button levers 200, four corresponding switches 300, four sets of support bars 420, and eight corresponding first protrusions 111 and second protrusions 121.

[0026] This embodiment also relates to a camera device, see reference Figures 7-9This includes the button structure described above. This camera device eliminates the need for a separate button control circuit board 600 and ribbon cable, reducing the number of components, simplifying the assembly process, lowering hardware costs and production time, and reducing the risk of button failure due to poor ribbon cable contact. Furthermore, the housing 100 includes a first chamber 510 and a second chamber 520. The switch 300 is located in the first chamber 510, and the button lever 200 is located in the second chamber 520. The housing 100 has a first through hole 122 to expose the first end 221 outside the housing 100, and a second through hole 123 connecting the first chamber 510 and the second chamber 520. The position of the second through hole 123 corresponds to the position of the switch 300. Specifically, the second outer shell 120 has a first chamber 510, and the second outer shell 110 and the second outer shell 120 form the second chamber 520. The second outer shell 120 has a first through hole 122 and a second through hole 123. The first through hole 122 is provided to allow the first end 221 of the button lever 200, i.e., the button portion 230 on the button lever 200, to be exposed outside the housing 100 so that the user can press the button portion 230 of the button lever 200. The second through hole 123 is provided so that one side of the trigger portion 240 of the button lever 200 can pass through to trigger the switch 300. In this embodiment, there are three button levers 200, three corresponding switches 300, and three corresponding second through holes 123.

[0027] Furthermore, the camera device also includes a control circuit board 600 disposed within the first chamber 510, and switches 300 disposed on and electrically connected to the control circuit board 600. In this embodiment, multiple switches 300 are arranged side-by-side on the control circuit board 600. The camera device also includes other components such as a lens and a power supply device.
