Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular to a four-way rocker switch with a pre-installed bottom shell. Background Technology

[0002] The inside of a rocker switch usually contains a metal spring (also known as a "dowel plate"). When the four-way rocker is rotated, the rocker presses the metal spring, causing the metal spring to be recessed and contact the two electrical pads below it, thus making the two electrical pads conductive.

[0003] In existing rocker switches, the metal spring is not pre-fixed to other components. Due to its light weight and small size, it is easily affected by vibration, airflow, and other factors during assembly, causing the metal spring to shift. Because the metal spring is prone to displacement, assembly workers need to spend a lot of time and effort adjusting its position to ensure it is correctly aligned with the electrical contact pad. This not only increases labor costs but also reduces production efficiency, negatively impacting the company's development.

[0004] Therefore, existing rocker switches need to be improved to solve the problem that the metal spring is prone to displacement during the assembly process, resulting in 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 pre-installed four-way rocker switch with a bottom shell, which can effectively solve the problem that the metal spring is prone to displacement during the assembly process, resulting in low assembly efficiency.

[0007] To achieve the above objectives, this utility model provides a pre-installed four-way rocker switch with a bottom shell, comprising:

[0008] The base is pre-assembled with an outer shell, which includes a square shell surrounding a cavity and several metal springs fixed to the bottom of the square shell.

[0009] A button panel, which is located within the accommodating cavity;

[0010] A four-way ball-head rocker, which is rotatably connected to the square housing, is used to press the button panel downwards when driven.

[0011] The circuit board is located below the pre-assembled housing of the base, and the circuit board is provided with a pair of conductive pads corresponding to the position of each of the metal springs;

[0012] The metal spring has an open state where it recovers its upward deformation and detaches from the two corresponding conductive pads when not under pressure, thus disconnecting the two conductive pads; and an open state where it moves downward under the drive of the four-way ball joint rocker arm to fit the two corresponding conductive pads, thus making the two conductive pads conductive.

[0013] Optionally, the metal spring is hot-riveted to the bottom of the square housing.

[0014] Optionally, the bottom of the square housing is provided with a spring positioning groove for the metal spring to enter and be positioned.

[0015] Optionally, the square 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.

[0016] Optionally, the housing base is provided with a lower clearance groove corresponding to the position of each pair of conductive pads.

[0017] Optionally, the keypad includes a connecting base plate, and the connecting base plate is provided with a reset keycap corresponding to the position of each of the lower clearance slots.

[0018] 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.

[0019] Optionally, the four-way ball joint is provided with a lateral pressure bar for pressing down on the reset keycap at the position of each of the reset keycaps, and the housing cover is provided with an upper clearance groove at the position of each of the lateral pressure bars.

[0020] Optionally, a flexible pressure block bracket is provided between the four-way ball joint and each of the reset keycaps, and each of the lateral pressure rods presses down on the corresponding reset keycap through the flexible pressure block bracket.

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

[0022] The beneficial effects of this utility model are as follows: It provides a four-way rocker switch with a pre-installed bottom shell. When the rocker switch is not operated, the metal spring is in an uncompressed state due to its elasticity. At this time, the metal spring returns to its original shape and disengages from the two conductive pads below it, so that the conductive pads are in an open state.

[0023] When the operator rotates the four-way ball joint, the four-way ball joint presses down on the button plate, which in turn transmits force to the metal spring through the button plate, causing the metal spring to move downward until it contacts the conductive pad below, thereby making the conductive pad conductive and completing the circuit closure.

[0024] In this design, the metal spring is pre-installed on the bottom of the square housing, corresponding to the conductive pads on the circuit board, rather than being left freely placed. This design reduces the degree of freedom of movement of the metal spring during assembly, lowering the risk of displacement due to vibration or airflow. Assembly workers do not need to position and fix the metal spring during assembly, which greatly simplifies the assembly process and reduces assembly time. Furthermore, because the position of the metal spring is pre-fixed, no fine-tuning of the spring is required during assembly, thereby reducing the possibility of assembly errors and improving production efficiency.

[0025] Therefore, the pre-installed four-way rocker switch in the bottom shell provided by this utility model can effectively solve the problem that the metal spring is easy to shift during the assembly process, resulting in low assembly efficiency. Attached Figure Description

[0048] See Figure 1 and Figure 2 This utility model provides a base-pre-installed four-way rocker switch, including a base-pre-installed outer shell 1, a button board 2, a four-way ball head rocker 3, and a circuit board 4.

[0049] The base pre-assembled housing 1 includes a square housing 101 surrounding a cavity, and a plurality of metal springs 102 fixed to the bottom of the square housing 101; the button plate 2 is located inside the cavity; the four-way ball joint rocker 3 is rotatably connected to the square housing 101 and is used to press the button plate 2 downward when driven; the circuit board 4 is located below the base pre-assembled housing 1, and the circuit board 4 is provided with a pair of conductive pads corresponding to the position of each metal spring 102.

[0050] The metal spring 102 has an open state where it recovers its upward deformation and detaches from the corresponding two conductive pads when not under pressure, thus disconnecting the two conductive pads; and an open state where it is driven downward by the four-way ball joint 3 to fit against the corresponding two conductive pads, thus making the two conductive pads conductive.

[0051] The pre-installed four-way rocker switch in the bottom shell provided in this embodiment has the following properties: when the rocker switch is not operated, the metal spring 102 is in an uncompressed state due to its elasticity. At this time, the metal spring 102 restores its upward deformation and disengages from the two conductive pads below it, so that the conductive pads are in an open state.

[0052] When the operator rotates the four-way ball joint 3, the four-way ball joint 3 presses down on the button plate 2, and then transmits the force to the metal spring 102 through the button plate 2, causing the metal spring 102 to move downward until it contacts the conductive pad below, thereby making the conductive pad conduct electricity and completing the circuit closure.

[0053] In this design, the metal spring 102 is pre-mounted on the bottom of the square housing 101, corresponding to the conductive pads on the circuit board 4, rather than being left freely placed. This design reduces the degree of freedom of movement of the metal spring 102 during assembly, lowering the risk of displacement due to vibration or airflow. Assembly workers do not need to position and fix the metal spring 102 during assembly, which greatly simplifies the assembly steps and reduces assembly time. Furthermore, due to the pre-fixed position of the metal spring 102, no fine-tuning of the spring is required during assembly, thereby reducing the possibility of assembly errors and improving production efficiency.

[0054] Therefore, the pre-installed four-way rocker switch with a bottom shell provided by this utility model can effectively solve the problem that the metal spring 102 is prone to displacement during the assembly process, resulting in low assembly efficiency.

[0055] Optionally, the metal spring 102 is hot-riveted to the bottom of the square housing 101. Specifically, the bottom of the housing base 1011 is provided with a spring positioning groove 1011c for the metal spring 102 to enter and position, so as to complete the positioning of the metal spring 102.

[0056] In this embodiment, the square housing 101 includes a housing base 1011 and a housing cover 1012 that covers the housing base 1011 and cooperates with the housing base 1011 to form the accommodating cavity. The housing base 1011 and the housing cover 1012 are snap-fit ​​connected. The housing base 1011 is provided with a lower clearance groove 1011a corresponding to the position of each pair of conductive pads.

[0057] The keypad 2 includes a connecting base plate 201, and a reset keycap 202 is provided at each position of the lower relief groove 1011a. When the four-way ball joint 3 presses down on the reset keycap 202, the reset keycap 202 can deform downward through the corresponding lower relief groove 1011a and contact the metal spring 102 directly below the lower relief groove 1011a, thereby applying downward pressure to the metal spring 102.

[0058] A flexible pressure block bracket 5 is provided between the four-way ball head rocker 3 and each of the reset keycaps 202. Each of the horizontal pressure rods 301 presses down on the corresponding reset keycap 202 through the flexible pressure block bracket 5.

[0059] The flexible pressure block bracket 5 plays a role in transmitting pressure, buffering, maintaining stability, and adapting to deformation in the pre-installed four-way rocker switch. It effectively transmits the movement and pressure of the four-way ball joint 3 to the reset keycap 202, while reducing hard contact during operation, lowering vibration and noise, and improving user comfort and switch lifespan. Furthermore, the flexible pressure block bracket 5 prevents the reset keycap 202 from excessively compressing the metal spring 102, protecting other sensitive components on the circuit board 4, simplifying the assembly process, and improving the overall reliability and lifespan of the product.

[0060] In this embodiment, the housing base 1011 is provided with an upwardly protruding ball joint 1011b, and the bottom of the four-way ball joint rocker 3 is provided with a spherical groove for the ball joint 1011b to be inserted. The four-way ball joint rocker 3 is provided with a transverse pressure rod 301 for pressing down on the reset keycap 202 at the position of each reset keycap 202, and the housing cover 1012 is provided with an upper clearance groove 1012a at the position of each transverse pressure rod 301.

[0061] The presence of the upper clearance groove 1012a ensures that even with a relatively small overall height of the square housing 101, the lateral pressure rod 301 has sufficient space during rocker arm movement and will not interfere with the housing cover 1012. This helps to further reduce the size of the compact rocker switch and improve the structural compactness.

[0062] Optionally, the number of transverse pressure bars 301 is four, and the four transverse pressure bars 301 form a cross structure.

[0063] See Figure 3 The assembly process of the pre-installed four-way rocker switch with a bottom shell provided in this embodiment is as follows:

[0064] S10: Install the four-way ball joint rocker 3, the flexible pressure block bracket 5, and the button plate 2 into the housing cover 1012 in sequence;

[0065] S20: Hot-rivet the metal spring 102 to the bottom of the housing base 1011 to ensure that the position of each metal spring 102 corresponds to the lower clearance groove 1011a on the circuit board 4;

[0066] S30: Connect the housing base 1011 to the housing cover 1012 via a snap-fit ​​connection;

[0067] S40: Secure the pre-assembled housing 1 onto the circuit board 4 to complete the assembly; see below. Figure 4 Furthermore, the bottom of the housing cover 1012 is provided with a positioning post 1012b that passes through the housing base 1011, and the circuit board 4 is provided with a positioning hole for the positioning post 1012b to be inserted, so that the alignment operation between the square housing 101 and the circuit board 4 can be completed.

[0068] Optionally, fasteners such as bolts can be used to fix the circuit board 4 to the bottom of the housing base 1011.

[0069] In summary, the pre-installed four-way rocker switch with a bottom shell provided in this embodiment has the following advantages:

[0070] ①Simplified assembly process: Since the metal spring 102 is pre-installed on the bottom of the square housing 101, the assembly workers do not need to position and fix the metal spring 102 during the assembly process, which greatly simplifies the assembly steps and reduces the assembly time.

[0071] ② Improve assembly efficiency: The pre-assembled design reduces the degree of freedom of movement of the metal spring 102 during the assembly process, reduces the risk of displacement due to vibration or airflow, thereby reducing the possibility of assembly errors and improving production efficiency.

[0072] ③ Improve product reliability: The pre-fixing of the metal spring 102 ensures the consistency of the position of the metal spring 102 of each switch, improves the quality stability of the product, and extends the service life of the switch.

[0073] ④ Reduce assembly errors: Since there is no need to fine-tune the metal spring 102, the possibility of human error is reduced, further improving the product qualification rate.

[0074] ⑤ Compact structure: By designing the upper clearance groove 1012a and the lower clearance groove 1011a, as well as the ball joint 1011b and the spherical groove, the square shell 101 can be designed to be smaller, which improves the structural compactness and is conducive to miniaturization design.

[0075] ⑥ Improve user comfort: The use of flexible pressure block bracket 5 reduces hard contact during joystick operation, reduces vibration and noise, and improves the user's operating experience.

[0076] ⑦ Low cost: The metal spring 102 is fixed to the bottom of the housing base 1011 by hot riveting. The process is mature and simple, the cost is low, and it is suitable for large-scale production.

[0077] 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.
