Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular to a bottomless two-way rocker structure. Background Technology

[0002] A two-way rocker switch typically includes a rectangular top cover, a base plate, and other components located between the rectangular top cover and the base plate. When assembling the rocker switch, after installing the other components into the rectangular top cover, the base plate is finally installed to seal the lower opening of the rectangular top cover.

[0003] For existing two-way rocker switches, on the one hand, the base plate itself requires material costs; on the other hand, the increased assembly process of the base plate will also lead to a decrease in overall production efficiency.

[0004] Therefore, this invention aims to improve existing two-way rocker switches to solve the problems of high material costs and low assembly efficiency.

[0005] 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

[0006] One objective of this invention is to provide a bottomless two-way rocker structure that can effectively solve the problems of high material cost and low assembly efficiency of existing two-way rocker switches.

[0007] To achieve the above objectives, this utility model provides a bottomless two-way rocker structure, comprising:

[0008] Rectangular top cover;

[0009] A silicone keypad is located below the rectangular top cover and is enclosed by the rectangular top cover to form an accommodating cavity; wherein, the silicone keypad includes a connecting base plate that seals the bottom opening of the rectangular top cover and a plurality of floating pressure blocks located on the connecting base plate;

[0010] A two-way rotating rocker arm is rotatably connected to the rectangular top cover and is used to press down the corresponding floating pressure block after being driven.

[0011] Optionally, the two sides of the two-way rocker arm are provided with transverse pivots for rotating and inserting into the inner wall of the rectangular top cover.

[0012] Optionally, the two-way rotating rocker arm is provided with a transverse pressure bar for pressing down on the floating pressure block at the position of the floating pressure block, and the rectangular top cover is provided with a housing clearance groove at the position of each transverse pressure bar.

[0013] Optionally, there are two transverse pressure bars, each transverse pressure bar is provided with two floating pressure blocks, and a U-shaped flexible pressure block is provided between the transverse pressure bar and the two corresponding floating pressure blocks. The U-shaped flexible pressure block is provided with an upwardly protruding force-bearing protrusion corresponding to the position of the transverse pressure bar.

[0014] Optionally, each of the top corners of the bottom surface of the rectangular top cover is provided with a downwardly protruding positioning boss;

[0015] Each apex of the connecting substrate is provided with a substrate positioning groove to avoid the corresponding positioning boss.

[0016] Optionally, the connecting substrate is provided with a plurality of key post clearance holes, and each key post clearance hole is provided with a floating pressure block;

[0017] The diameter of the floating pressure block is smaller than the diameter of the key post clearance hole.

[0018] Optionally, the floating pressure block is connected to the wall of the keyway clearance hole via an elastic arm.

[0019] Optionally, the rectangular top cover is provided with bolt posts for fastening to an external circuit board, so as to cooperate with the circuit board to press the connecting substrate;

[0020] The connecting base plate is provided with a U-shaped clearance groove corresponding to the position of the bolt post.

[0021] Optionally, the bottom of the rectangular top cover is provided with a positioning post that protrudes downward to be inserted into the circuit board for positioning;

[0022] The connecting base plate has through holes corresponding to the positions of the positioning posts, allowing the positioning posts to pass through.

[0023] Optionally, the positioning post and the through hole are interference-fitted.

[0024] The beneficial effects of this utility model are as follows: It provides a bottomless two-way rocker structure. When in use, the bottomless two-way rocker structure is first installed and fixed on the circuit board, and each floating pressure block corresponds to each electronic button on the circuit board.

[0025] When the joystick switch is not operated, the metal spring is in an uncompressed state due to its elasticity. At this time, the floating pressure block returns to its original shape and releases the electronic button below it, so that the electronic button is in the off state.

[0026] When the operator rotates the two-way rocker arm, the rocker arm presses down on the floating block, which in turn presses down on the electronic button, thus turning on the electronic button and closing the circuit.

[0027] In the above process, the bottom opening of the rectangular top cover is directly sealed with a silicone button plate, so there is no need to use a base plate or assemble the base plate. Therefore, it can effectively solve the problems of high material cost and low assembly efficiency of existing two-way rocker switches. Attached Figure Description

[0045] See Figures 1-3 This utility model provides a bottomless two-way rocker structure, including a rectangular top cover 1, a silicone button plate 2, and a two-way rotating rocker 3.

[0046] The silicone keypad 2 is located below the rectangular top cover 1, and together with the rectangular top cover 1, it surrounds and forms an accommodating cavity. The silicone keypad 2 includes a connecting base plate 201 that seals the bottom opening of the rectangular top cover 1, and several floating pressure blocks 202 located on the connecting base plate 201. The two-way rotating rocker arm 3 is rotatably connected to the rectangular top cover 1 and is used to press down on the corresponding floating pressure block 202 when driven.

[0047] When using the bottomless two-way rocker structure provided in this embodiment, first install and fix the bottomless two-way rocker structure onto the circuit board, and make each floating pressure block 202 correspond to each electronic button on the circuit board.

[0048] When the joystick switch is not operated, the metal spring is in an unpressed state due to its elasticity. At this time, the floating pressure block 202 returns to its original shape and releases the electronic button below it, so that the electronic button is in the off state.

[0049] When the operator rotates the two-way rocker arm 3, the two-way rocker arm 3 presses down on the floating pressure block 202, which in turn presses down on the electronic button, thereby turning on the electronic button and completing the circuit closure.

[0050] In the above process, the bottom opening of the rectangular top cover 1 is directly sealed by the silicone button plate 2, so there is no need to use a base plate, nor is there any need to assemble the base plate. Therefore, it can effectively solve the problems of high material cost and low assembly efficiency of existing two-way rocker switches.

[0051] Optionally, the two-way rocker arm 3 is provided with transverse rocker arms 302 on both sides for rotating and inserting into the inner wall of the rectangular top cover 1.

[0052] The bidirectional rocker arm 3 is provided with a transverse pressure bar 301 for pressing down on the floating pressure block 202 at the position corresponding to the floating pressure block 202. The rectangular top cover 1 is provided with a housing clearance groove 101 corresponding to each of the transverse pressure bars 301. The existence of the housing clearance groove 101 ensures that even if the overall height of the rectangular top cover 1 is designed to be small, the transverse pressure bars 301 have sufficient space during rocker arm movement and will not interfere with the rectangular top cover 1. This helps to further reduce the size of the compact rocker switch and improve the structural compactness.

[0053] There are two transverse pressure bars 301. Each transverse pressure bar 301 is provided with two floating pressure blocks 202. A U-shaped flexible pressure block 4 is provided between the transverse pressure bar 301 and the two corresponding floating pressure blocks 202. The U-shaped flexible pressure block 4 is provided with an upwardly protruding force-bearing protrusion 401 corresponding to the position of the transverse pressure bar 301.

[0054] In the baseless two-way rocker structure, the U-shaped flexible pressure block 4 plays a role in transmitting pressure, buffering, maintaining stability, and adapting to deformation. It effectively transmits the movement and pressure of the two-way rotating rocker 3 to the floating pressure block 202, while reducing hard contact during operation, lowering vibration and noise, and improving user comfort and switch lifespan. Furthermore, the U-shaped flexible pressure block 4 also prevents the floating pressure block 202 from excessively pressing the electronic buttons.

[0055] In this embodiment, each corner of the bottom surface of the rectangular top cover 1 is provided with a downwardly protruding positioning boss 104; each corner of the connecting substrate 201 is provided with a substrate positioning groove 2012 that avoids the corresponding positioning boss 104. The positioning bosses 104 cooperate with each other to complete the horizontal relative positioning of the rectangular top cover 1 and the silicone button plate 2.

[0056] Optionally, the connecting substrate 201 is provided with a plurality of keypost clearance holes 2014, and each keypost clearance hole 2014 contains a floating pressure block 202; wherein the diameter of the floating pressure block 202 is smaller than the diameter of the keypost clearance hole 2014. The floating pressure block 202 is connected to the hole wall of the keypost clearance hole 2014 via an elastic arm 203.

[0057] In this embodiment, the rectangular top cover 1 is provided with bolt posts 103 for fastening to an external circuit board, so as to cooperate with the circuit board to press the connecting substrate 201; the connecting substrate 201 is provided with a U-shaped clearance groove 2011 corresponding to the position of the bolt posts 103.

[0058] During assembly, the fastener is threaded through the circuit board and screwed into the bolt post 103. After tightening, the circuit board can clamp the silicone keypad 2 in the middle with the rectangular top cover 1, thereby completing the vertical relative positioning of the rectangular top cover 1 and the silicone keypad 2.

[0059] Optionally, the bottom of the rectangular top cover 1 is provided with a positioning post 102 that protrudes downward to be inserted into the circuit board for positioning; the connecting base plate 201 is provided with a through hole 2013 corresponding to the position of the positioning post 102 for the positioning post 102 to pass through. Further, the positioning post 102 and the through hole 2013 are interference-fitted. Before the bottomless two-way rocker structure is installed on the circuit board, pre-positioning is mainly achieved by the interference fit between the positioning post 102 and the through hole 2013 to prevent internal components from falling outwards.

[0060] In summary, the bottomless two-way rocker structure provided in this embodiment has the following advantages:

[0061] ① Simple structure: No base plate design is required, which reduces the number of components, simplifies the assembly process, and reduces material costs;

[0062] ② Reduced size: No base plate is needed, making the overall structure more compact and facilitating miniaturization design;

[0063] ③ Accurate positioning: The positioning boss 104 and the substrate positioning groove 2012 cooperate to achieve the horizontal positioning of the silicone keypad 2, and the bolt post 103 designed to be fastened to the circuit board achieves the vertical positioning of the silicone keypad 2.

[0064] ④ Comfortable to use: The design of the U-shaped flexible pressure block 4 reduces hard contact, reduces vibration and noise, and improves the comfort of use and the life of the switch;

[0065] ⑤ Good stability: The combination of floating pressure block 202 and U-shaped flexible pressure block 4 ensures the stability of pressure transmission and the ability to adapt to deformation;

[0066] ⑥ Pre-positioning function: The interference fit between the positioning post 102 and the through hole 2013 ensures the stability of the internal components during installation and prevents the components from falling off.

[0067] 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.
