Description

Technical Field

[0001] This utility model relates to the field of electrical component technology, and in particular to a compact rocker switch. Background Technology

[0002] In modern electronic devices, joystick switches are a common input device widely used in game controllers, remote controls, industrial control systems, and other fields. The design and performance of joystick switches directly affect the user experience and reliability of electronic devices.

[0003] Existing joystick switches mainly consist of three parts: a circuit board, an electronic button, and a four-way joystick. The circuit board, as the core component of the joystick switch, is responsible for receiving and processing button signals. The electronic button, soldered and fixed to the circuit board, converts the movement of the four-way joystick into electrical signals. The four-way joystick is located above the electronic button; by shaking the joystick, the user can move it in four directions (up, down, left, and right) to achieve different operating commands.

[0004] When the user shakes the four-way joystick, the joystick presses down on the electronic button. Upon receiving pressure, the internal contacts of the electronic button close, sending a button signal to the circuit board. The circuit board then uses this signal to control the electronic device.

[0005] Electronic buttons have complex internal structures and are relatively large in height. This results in a large overall height for rocker switches, reducing their structural compactness and hindering the miniaturization and thinning of electronic devices.

[0006] Therefore, existing rocker switches need to be improved to address their large size.

[0007] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0008] One objective of this invention is to provide a compact rocker switch that effectively solves the problem of the large size of existing rocker switches.

[0009] To achieve the above objectives, this utility model provides a compact rocker switch, comprising:

[0010] A switch housing, the switch housing surrounding and forming a receiving cavity;

[0011] A circuit board is installed inside the accommodating cavity, and a plurality of sets of pad assemblies are provided on the top surface of the circuit board; each set of pad assemblies includes two spaced-apart conductive pads.

[0012] A plurality of reset caps are provided, with one reset cap above each group of the solder pad assembly, and a conductive sheet is provided on the top of the inner wall of the reset cap;

[0013] A four-way ball-head rocker arm is rotatably connected to the switch housing and is used to press down on each of the reset caps after being driven.

[0014] The conductive sheet has a disconnected state, which is driven upward by the reset cap to detach from the two conductive pads, thus disconnecting the two conductive pads; and a connected state, which is driven downward by the four-way ball joint to adhere to the two conductive pads, thus connecting the two conductive pads.

[0015] Optionally, the reset cap includes a flared portion that gradually expands from top to bottom, and a cylindrical portion fixed to the top of the flared portion;

[0016] The conductive sheet is fixed to the bottom surface of the cylindrical portion.

[0017] Optionally, the cylindrical portion and the horn portion are integrally injection molded structures.

[0018] Optionally, the cylindrical portion and the conductive sheet are in-mold injection molded structures.

[0019] Optionally, the switch housing includes a housing base and a housing cover disposed above the housing base and cooperating with the housing base to form the accommodating cavity.

[0020] Optionally, the housing base is provided with an upwardly protruding ball joint, and the bottom of the four-way ball joint is provided with a spherical groove for the ball joint to be inserted.

[0021] Optionally, the housing base and the housing cover are snap-fitted together.

[0022] Optionally, the four-way ball joint rocker is provided with a plurality of lateral pressure rods for pressing down the reset cap, and the housing cover is provided with a clearance groove corresponding to the position of each of the lateral pressure rods.

[0023] Optionally, the number of lateral compression bars is four.

[0024] Optionally, a flexible pressure block bracket is provided between the four-way ball joint and each of the reset caps, and each of the transverse pressure rods presses down one or two of the reset caps through the flexible pressure block bracket.

[0025] The beneficial effects of this utility model are as follows: It provides a compact rocker switch. Under normal circumstances, the reset cap drives the conductive sheet to move upward until it disengages from the two conductive pads, and each set of pad assemblies is in an open state. When the four-way ball-head rocker is rocked, the four-way ball-head rocker presses down on each of the reset caps, causing the conductive sheet to move downward to fit against the two conductive pads. At this time, the two conductive pads are connected through the conductive sheet. After the circuit board receives the connection signal, it can respond to the button operation. After the four-way ball-head rocker is released, the pressed reset caps return to their original shape, thereby causing the four-way ball-head rocker to reset and the pad assemblies to return to the open state.

[0026] The compact rocker switch provided in this embodiment eliminates the complex and large internal structure of the electronic button in traditional rocker switches, and uses a simpler reset cap, conductive sheet, and solder pad assembly to achieve circuit conduction function.

[0027] The conductive plate on the top of the inner wall of the reset cap directly contacts the solder pad, reducing unnecessary intermediate structural layers and thus lowering the overall height of the switch. The four-way ball joint directly drives the reset cap, allowing the switch to maintain its functionality while being smaller in size, making it more suitable for electronic devices that require miniaturization and thinner design.

[0028] Therefore, the compact rocker switch provided by this utility model can effectively solve the problem of the large size of existing rocker switches. Attached Figure Description

[0047] See Figure 1 and Figure 2 The compact rocker switch provided in this embodiment includes a switch housing 1, a circuit board 2, several reset caps 3, and a four-way ball head rocker 4.

[0048] The switch housing 1 surrounds and forms a receiving cavity. The circuit board 2 is installed in the receiving cavity, and the top surface of the circuit board 2 is provided with several sets of pad assemblies; each set of pad assemblies includes two spaced-apart conductive pads 201. A reset cap 3 is provided above each set of pad assemblies, and the top of the inner wall of the reset cap 3 is provided with a conductive sheet 301. The four-way ball joint rocker 4 is rotatably connected to the switch housing 1 and is used to press down on each reset cap 3 when driven.

[0049] The conductive sheet 301 has a disconnected state, which is driven upward by the reset cap 3 to detach from the two conductive pads 201, thus disconnecting the two conductive pads 201; and a connected state, which is driven downward by the four-way ball joint rocker 4 to adhere to the two conductive pads 201, thus connecting the two conductive pads 201.

[0050] In this embodiment, the compact rocker switch typically operates as follows: The reset cap 3 drives the conductive sheet 301 upwards to disengage from the two conductive pads 201, with each pad assembly in an open state. When the four-way ball joint 4 is rocked, it presses down on each reset cap 3, causing the conductive sheet 301 to move downwards and adhere to the two conductive pads 201. At this point, the two conductive pads 201 are connected through the conductive sheet 301. Upon receiving the connection signal, the circuit board 2 can respond to button operations. Releasing the four-way ball joint 4 restores the pressed reset cap 3's deformation, thereby resetting the four-way ball joint 4 and restoring the pad assembly to its open state.

[0051] The compact rocker switch provided in this embodiment eliminates the complex and large internal structure of the electronic button in traditional rocker switches, and uses a simpler reset cap 3, conductive sheet 301, and pad assembly to achieve circuit conduction function.

[0052] The conductive plate 301 on the top of the inner wall of the reset cap 3 directly contacts the solder pad, reducing unnecessary intermediate structural layers and thus lowering the overall height of the switch. The four-way ball joint 4 directly drives the reset cap 3, making the switch smaller and more suitable for miniaturized and thinner electronic devices while maintaining its functionality.

[0053] Therefore, the compact rocker switch provided by this utility model can effectively solve the problem of the large size of existing rocker switches.

[0054] In this embodiment, the reset cap 3 includes a flared portion 302 that gradually expands from top to bottom, and a cylindrical portion 303 fixed to the top of the flared portion 302; wherein, the conductive sheet 301 is fixed to the bottom surface of the cylindrical portion 303. The design of the flared portion 302 and the cylindrical portion 303 of the reset cap 3 increases the stability of the structure, enabling the conductive sheet 301 to accurately operate the pad assembly when driven by the four-way ball joint 4.

[0055] The structural design of the horn section 302 has the following advantages:

[0056] ① Increased stability: The gradually expanding structure can provide a larger contact area, making the reset cap 3 more stable when pressed by the four-way ball head rocker 4, reducing shaking and improving the accuracy and reliability of operation.

[0057] ② Distribute pressure: This structure helps to evenly distribute the pressure applied by the four-way ball joint 4 onto the reset cap 3, reducing local pressure concentration and thus extending the service life of the reset cap 3.

[0058] ③ Improved reset effect: The progressive structure ensures that the reset cap 3 can quickly and effectively return to the initial position after the four-way ball head rocker 4 is released, ensuring the rapid reset of the switch.

[0059] ④ Easy to operate: Due to the shape design of the horn part 302, the operator can more easily control the reset cap 3 through the four-way ball head rocker 4, providing a more comfortable grip and operating experience.

[0060] Optionally, the cylindrical portion 303 and the horn portion 302 are integrally injection molded structures, while the cylindrical portion 303 and the conductive sheet 301 are in-mold injection molded structures. That is, the cylindrical portion 303, the horn portion 302, and the conductive sheet 301 are integrally injection molded structures. This improves manufacturing efficiency, reduces assembly steps, and lowers manufacturing costs; it also ensures a strong bond between the conductive sheet 301 and the cylindrical portion 303, improving the product's durability and long-term reliability.

[0061] In this embodiment, the switch housing 1 includes a housing base 101 and a housing cover 102 that covers the housing base 101 and cooperates with the housing base 101 to form the accommodating cavity.

[0062] Optionally, the housing base 101 is provided with an upwardly protruding ball joint 1011, and the bottom of the four-way ball joint rocker 4 is provided with a spherical groove for the ball joint 1011 to be inserted. The design of the ball joint 1011 and the spherical groove allows the four-way ball joint rocker 4 to rotate flexibly, improving the sensitivity and comfort of operation.

[0063] Optionally, the housing base 101 and the housing cover 102 are snap-fit ​​connected. The snap-fit ​​connection between the housing base 101 and the housing cover 102 simplifies the assembly process and facilitates quick assembly and disassembly.

[0064] In this embodiment, the four-way ball-head rocker 4 is provided with a plurality of lateral pressure rods 401 for pressing down on the reset cap 3. The housing cover 102 is provided with a clearance groove 1021 corresponding to the position of each of the lateral pressure rods 401. The existence of the clearance groove 1021 ensures that even if the overall height of the switch housing 1 is designed to be small, the lateral pressure rods 401 have sufficient space during rocker movement and will not interfere with the housing cover 102. This is beneficial for further reducing the size of the compact rocker switch and improving structural compactness.

[0065] Optionally, the number of transverse pressure bars 401 is four, and the four transverse pressure bars 401 form a cross structure.

[0066] Optionally, a flexible pressure block bracket 5 is provided between the four-way ball head rocker 4 and each of the reset rubber caps 3. Each of the transverse pressure rods 401 presses down on one or two of the reset rubber caps 3 through the flexible pressure block bracket 5, so as to disperse the pressing force of the transverse pressure rods 401 and improve the rebound reset feel.

[0067] In summary, the compact rocker switch provided in this embodiment has the following advantages:

[0068] ① Reduced size: By simplifying the internal structure and eliminating the complex electronic buttons in traditional rocker switches, the overall switch size is smaller, which is beneficial for miniaturization and thinning of electronic devices.

[0069] ②Simplified structure: The circuit conduction function is achieved by using a reset cap 3, conductive sheet 301 and pad assembly, which reduces the number of components and complexity, and lowers production costs and maintenance difficulty.

[0070] ③ Manufacturing efficiency: The integrated in-mold injection molding structure of the horn part 302, cylindrical part 303, and conductive sheet 301 facilitates large-scale production, improves production efficiency, and reduces manufacturing costs.

[0071] ④ Easy assembly: The snap-fit ​​connection between the housing base 101 and the housing cover 102 simplifies the assembly process, making it easy to assemble and disassemble quickly and for easy maintenance.

[0072] ⑤ Compact structure: The design of the transverse pressure bar 401 and the clearance groove 1021 ensures the movement space of the four-way ball head rocker 4 even with a small switch housing 1 height dimension, further reducing the volume of the switch and improving the compactness of the structure.

[0073] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
