Description

Technical Field

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

[0002] A four-way rocker switch typically includes a square top cover, a base plate, and other components located between the square top cover and the base plate. When assembling the rocker switch, after installing the other components into the square top cover, the base plate must be installed last to seal the lower opening of the square top cover.

[0003] For existing four-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 utility model aims to improve the existing four-way rocker switch to solve the problems of high material cost 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 baseless four-way rocker structure that can effectively solve the problems of high material costs and low assembly efficiency of existing four-way rocker switches.

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

[0008] Square top cover;

[0009] A square flexible key plate is located below a square top cover and is used in conjunction with the square top cover to form an accommodating cavity; wherein, the square flexible key plate includes a silicone substrate that seals the bottom opening of the square top cover and a plurality of floating key posts located on the silicone substrate;

[0010] A four-way ball-head rocker arm, which is rotatably connected to the square top cover, is used to press down on the corresponding floating key post after being driven.

[0011] Optionally, the four-way ball joint rocker arm is provided with a spherical body, and the inner top wall of the square top cover is provided with a spherical groove that is adapted to the spherical body.

[0012] Optionally, the spherical body is provided with a transverse pressure bar for pressing down on the floating key column at the position of the floating key column, and the square top cover is provided with a housing clearance groove at the position of each transverse pressure bar.

[0013] Optionally, the number of transverse pressure bars is four, each transverse pressure bar is provided with two floating key pillars, and a U-shaped flexible pressure block is provided between the transverse pressure bar and the two corresponding floating key pillars. 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, the bottom surface of the square top cover is provided with a pair of downwardly protruding positioning bosses at the positions of the top corners;

[0015] The silicone substrate has a substrate positioning groove at the top corner to avoid the corresponding positioning boss.

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

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

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

[0019] Optionally, the square top cover is provided with stud holes for fastening to an external circuit board, so as to cooperate with the circuit board to press the silicone substrate;

[0020] The silicone substrate has a U-shaped clearance groove corresponding to the position of the stud hole.

[0021] Optionally, the bottom of the square top cover is provided with positioning posts that protrude downwards at the other pair of apex corners for insertion into the circuit board for positioning;

[0022] The silicone substrate 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 four-way rocker structure. When in use, the bottomless four-way rocker structure is first installed and fixed on the circuit board, so that each floating key column 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 key column 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 four-way ball joint, the four-way ball joint presses down on the floating key post, 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 square top cover is directly sealed by a square flexible key 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 four-way rocker switches. Attached Figure Description

[0045] See Figures 1-3 This utility model provides a bottomless four-way rocker structure, including a square top cover 1, a square flexible key plate 2, and a four-way ball head rocker 3.

[0046] The square flexible key plate 2 is located below the square top cover 1, and together with the square top cover 1, it surrounds and forms an accommodating cavity. The square flexible key plate 2 includes a silicone substrate 201 that seals the bottom opening of the square top cover 1, and a plurality of floating key posts 202 located on the silicone substrate 201. The four-way ball joint rocker 3 is rotatably connected to the square top cover 1 and is used to press down on the corresponding floating key post 202 when driven.

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

[0048] When the joystick switch is not operated, the metal spring is in an uncompressed state due to its elasticity. At this time, the floating key post 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 four-way ball joint 3, the four-way ball joint 3 presses down on the floating key post 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 square top cover 1 is directly sealed by the square flexible key 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 four-way rocker switches.

[0051] Optionally, the four-way ball head rocker arm 3 is provided with a spherical body 302, and the inner top wall of the square top cover 1 is provided with a spherical groove that is adapted to the spherical body 302.

[0052] The spherical body 302 is provided with a transverse pressure bar 301 for pressing down on the floating key 202 at the position corresponding to the floating key 202. The square 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 square top cover 1 is designed to be small, the transverse pressure bar 301 has sufficient space during rocker arm movement and will not interfere with the square top cover 1. This helps to further reduce the size of the compact rocker arm switch and improve the structural compactness.

[0053] There are four transverse pressure rods 301. Each transverse pressure rod 301 is provided with two floating key pillars 202. A U-shaped flexible pressure block 4 is provided between the transverse pressure rod 301 and the two corresponding floating key pillars 202. The U-shaped flexible pressure block 4 is provided with an upwardly protruding force-bearing protrusion 401 at the position corresponding to the transverse pressure rod 301.

[0054] In the baseless four-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 four-way ball joint rocker 3 to the floating key post 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 key post 202 from excessively pressing the electronic buttons.

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

[0056] Optionally, the silicone substrate 201 is provided with a plurality of keypost clearance holes 2011, and each keypost clearance hole 2011 contains a floating keypost 202; wherein the diameter of the floating keypost 202 is smaller than the diameter of the keypost clearance hole 2011. The floating keypost 202 is connected to the hole wall of the keypost clearance hole 2011 by an elastic arm 203.

[0057] In this embodiment, the square top cover 1 is provided with a stud hole 103 for fastening to an external circuit board, so as to cooperate with the circuit board to press the silicone substrate 201; optionally, the stud hole 103 is located in the positioning boss 104 to further improve the structural compactness of the product.

[0058] During assembly, the fastener is threaded through the circuit board and screwed into the stud hole 103. After tightening, the circuit board can clamp the square flexible key plate 2 in the middle with the square top cover 1, thereby completing the vertical relative positioning of the square top cover 1 and the square flexible key plate 2.

[0059] Optionally, the bottom of the square top cover 1 has a pair of downwardly protruding positioning posts 102 at its other apex for insertion into the circuit board for positioning; the silicone substrate 201 has through holes 2013 corresponding to the positions of the positioning posts 102 for the positioning posts 102 to pass through. Further, the positioning posts 102 and the through holes 2013 are interference-fitted. Before the baseless four-way rocker structure is installed on the circuit board, pre-positioning is mainly achieved through the interference fit between the positioning posts 102 and the through holes 2013, preventing internal components from falling out.

[0060] In summary, the bottomless four-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 square flexible key plate 2, and the stud hole 103 designed to be fastened to the circuit board is used to achieve the vertical positioning of the square flexible key plate 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 the floating key column 202 and the 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.
