Description

Technical Field

[0001] This utility model relates to the field of push button switch devices, and in particular to a combined push button switch device. Background Technology

[0002] Currently, traditional push-button switches generally adopt a discrete button structure, meaning each button is installed independently and not connected to others. This design has obvious drawbacks: on the one hand, during assembly, multiple buttons are prone to misinstallation, misalignment, or omission due to inaccurate positioning, significantly reducing assembly efficiency and affecting product consistency; on the other hand, the discrete structure makes it difficult to form an effective seal between the button and the housing, failing to effectively prevent external dust intrusion and accidental water splashes, leading to internal contact contamination, oxidation, or even short circuits, affecting product reliability.

[0003] Existing push-button switches typically rely on the mechanical switch's own reset force (such as the return of a spring) to return the button to its original position. After prolonged use, the spring is prone to fatigue and failure, causing the button to rebound slowly or become stuck. This not only affects the operating feel but also significantly shortens the overall lifespan of the device.

[0004] In summary, traditional discrete push-button switches have significant shortcomings in terms of assembly convenience, environmental protection, and durability, and there is an urgent need for a new push-button structure solution that is integrated, well-sealed, and has a reliable reset mechanism.

[0020] The present invention will now be described in detail with reference to specific embodiments. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0021] It should be noted that, unless otherwise expressly specified and limited, the terms "extend", "embedded", "located in", "towards", "protruding from", "inside", "outside", "thickness direction", "retracted", "entering", etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. The terms "installation," "fitting," "connection," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixing" can be bolt fixing, snap-fit ​​fixing, or glue fixing. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. "A plurality" or "several" means two or more. In addition, "and / or" includes any and all combinations of one or more of the related listed items. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] In this embodiment, the specific implementation of the "combination push-button switch device" is not limited. Those skilled in the art can selectively use any suitable implementation method according to actual needs.

[0023] The term "discrete form" refers to a component or structure that has an independent, single function, with each unit existing autonomously and not depending on others; for example, cantilever and rocker buttons in mechanical buttons, each button is physically independent and is triggered by a fixed cantilever or shaft, but each button still maintains structural independence.

[0024] The term "yin-yang interlocking structure" refers to a structure that achieves seamless connection through the complementary forms of concave (yin) and convex (yang).

[0025] In the following description, such as Figures 1-8As shown, the following situations exist: the thickness direction of the substrate 121 or the thickness direction of the PCB module 41 is set as the Z direction, the process of the contact portion 122 moving from the second surface of the substrate 121 to the first surface of the substrate 121 or the force portion 125 at least partially passing through the guide hole 1211 and retracting into the contact portion 122 is set as reset or return, and the position of the contact portion 122 when it is not pressed by the user is set as the initial position for explanation.

[0026] It should be noted that this combination key switch device is used in electronic devices, such as calculators and full-keyboard mobile phones.

[0027] Please see Figures 1-8 The combined push-button switch device includes: a push-button assembly 1 and a housing assembly.

[0028] It is understood that the housing assembly includes at least a button panel 21 and a display screen 22.

[0029] In this embodiment, the button panel 21 is used to support the button assembly 1, that is, the button assembly 1 is mounted on the button panel 21; the display screen 22 can display input information and / or output information, thereby enabling the combined button switch device to have a visual function.

[0030] The button assembly 1 includes a support frame 11 and multiple buttons 12. The support frame 11 is provided with multiple elastic arms 111. The button 12 has a base plate 121, a contact portion 122 and a first protective wall 123, and the contact portion 122 and the first protective wall 123 both protrude from the same side of the base plate 121.

[0031] In addition, each button 12 is connected to the support frame 11 via a corresponding elastic arm 111. This allows the combined push button switch device to return or reset the button 12 to its original position during use, whereas traditional push button switch devices can only rely on traditional switches to drive traditional buttons to their original position. Therefore, compared with traditional push button switch devices, this combined push button switch device has a longer service life.

[0032] In addition, the support frame 11, multiple elastic arms 111 and multiple buttons 12 are integrated into one structure, which makes it less likely for the multiple buttons 12 to be installed incorrectly or misaligned during assembly, thus facilitating the assembly of the multiple buttons 12.

[0033] In this embodiment of the application, the housing assembly has a first inner surface 2101, which is specifically located inside the button panel 21. The housing assembly is provided with a plurality of through holes 211 and a plurality of second protective walls 212, which are located inside the housing assembly and protrude from the first inner surface 2101.

[0034] To further explain, multiple through holes 211 and multiple second protective walls 212 are all provided on the button panel 21.

[0035] Specifically, the projection of the second protective wall 212 on the first inner surface 2101 covers the projection of the through hole 211 on the first inner surface 2101, which means that the through hole 211 is located inside the second protective wall 212. This design ensures that dust or moisture entering from the through hole 211 can only enter the housing assembly along the inner wall of the second protective wall 212.

[0036] It should be noted that one end of the contact portion 122 is located inside the first protective wall 123, which means that at least a portion of the contact portion 122 is located inside the first protective wall 123. This design ensures that dust or moisture entering through the gap between the through hole 211 and the contact portion 122 can only enter the housing assembly along the inner wall surface of the first protective wall 123.

[0037] It is understood that the other end of the contact portion 122 extends through the through hole 211 to the outside of the housing assembly. The contact portion 122 can be understood as providing a pressing contact for the user or a structure for bearing external force. Therefore, at least a portion of the contact portion 122 must be exposed outside the housing assembly to facilitate the user pressing the contact portion 122 or applying external force to the contact portion 122.

[0038] To further explain, when the button assembly 1 is assembled onto the housing assembly (or button panel 21), the first protective wall 123 abuts against the first inner surface 2101, and the second protective wall 212 is embedded in the first protective wall 123 and abuts against the substrate 121. This design makes the first protective wall 123 and the second protective wall 212 form a male-female interlocking structure, thereby effectively preventing dust and moisture from entering the interior of the housing assembly through the gap between the through hole 211 and the contact part 122.

[0039] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the combined push-button switch device also includes a positioning component.

[0040] The positioning component includes multiple positioning posts 31 and multiple positioning holes 32, and the positioning posts 31 are adapted to the positioning holes 32.

[0041] In addition, a plurality of positioning posts 31 are provided on one of the support frame 11 and the housing assembly (or the button panel 21), and a plurality of positioning holes 32 are provided on the other of the support frame 11 and the housing assembly (or the button panel 21).

[0042] In addition, when the positioning hole 32 is provided on the button panel 21, the positioning hole 32 is preferably a blind hole. This design can prevent the positioning post 31 that is compatible with the positioning hole 32 from being exposed outside the housing assembly. When the positioning hole 32 is provided on the support frame 11, the positioning hole 32 can be a through hole or a blind hole.

[0043] In this embodiment of the application, the positioning hole 32 of the combined push button switch device is a through hole opened on the support frame 11, while the positioning post 31 is disposed on the button panel 21 and protrudes from the first inner surface 2101.

[0044] To further explain, the button assembly 1 is assembled to the housing assembly (or button panel 21) through the mutual cooperation of the positioning post 31 and the positioning hole 32. This design can provide reliable positioning for the process of assembling the button assembly 1 to the button panel 21, thereby preventing the button 12 from shifting or misaligning, and thus simplifying the assembly process of both.

[0045] It should be noted that each button 12 has a different character on the top of its contact portion 122, and the character is made of transparent or semi-transparent material, while the other parts of the button 12 are made of non-transparent material.

[0046] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the substrate 121 has a first surface and a second surface opposite each other in the Z direction, and both the contact portion 122 and the first protective wall 123 protrude from the first surface of the substrate 121.

[0047] The substrate 121 has a guide hole 1211, which extends through the first and second surfaces of the substrate 121.

[0048] In addition, when the button assembly 1 is assembled onto the housing assembly (or button panel 21), the end of the second protective wall 212 facing away from the first inner surface 2101 abuts against the first surface of the substrate 121.

[0049] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, button 12 also includes a light-shielding wall 124 and a force-bearing part 125.

[0050] It should be noted that the light-shielding wall 124 protrudes from the second surface of the substrate 121.

[0051] It is understandable that one end of the force-applying part 125 is located inside the contact part 122, and the other end of the force-applying part 125 faces the interior of the light-shielding wall 124.

[0052] In some embodiments, such as Figure 4 and Figure 7 As shown, the guide hole 1211 is connected to the interior of the contact part 122 and the interior of the light-shielding wall 124, respectively.

[0053] Specifically, at least a portion of the force-applying part 125 can follow the movement of the contact part 122 through the guide hole 1211 into the light-shielding wall 124 or retract into the contact part 122.

[0054] In some embodiments, such as Figure 3 and Figure 4 As shown, one end of the elastic arm 111 is connected to the support frame 11, and the other end of the elastic arm 111 is connected to the substrate 121.

[0055] In this embodiment, the elastic arm 111 is used to provide elastic force, and the elastic force can limit the movement of the contact portion 122 from the first surface of the substrate 121 to the second surface of the substrate 121.

[0056] In some embodiments, such as Figure 3 , Figure 4 and Figure 6 As shown, an external force is applied to the contact portion 122, and the external force overcomes the elastic force to force the contact portion 122 to move from the first surface of the substrate 121 to the second surface of the substrate 121.

[0057] Specifically, when the contact portion 122 moves from the first surface of the substrate 121 to the second surface of the substrate 121, at least a portion of the force-applying portion 125 passes through the guide hole 1211 and enters the light-shielding wall 124.

[0058] In some embodiments, such as Figure 3 , Figure 4 and Figure 6 As shown, when the external force is removed, the elastic force can force the contact portion 122 to move from the second surface of the substrate 121 to the first surface of the substrate 121.

[0059] It should be noted that when the contact portion 122 moves from the second surface of the substrate 121 to the first surface of the substrate 121, at least a portion of the force-applying portion 125 retracts into the contact portion 122 through the guide hole 1211, thereby resetting or returning the contact portion to its initial position.

[0060] In some embodiments, such as Figure 1 , Figure 5 and Figure 7 As shown, the combined push-button switch device also includes: switch assembly 4.

[0061] The switch assembly 4 is located inside the housing assembly.

[0062] In addition, the switch assembly 4 includes a PCB module 41 and a plurality of switches 42, the switches 42 being disposed on the PCB module 41, and the light-shielding wall 124 being fitted onto the switches 42.

[0063] Furthermore, the contact portion 122 can move from the first surface of the substrate 121 to the second surface of the substrate 121, thereby driving the force portion 125 into the light-shielding wall 124 to press the switch 42 at one end.

[0064] It should be noted that during the assembly of the combined push button switch device, the user first sets the positioning hole 32 onto the positioning post 31 to achieve reliable positioning, thereby assembling the button assembly 1 onto the housing assembly (or button panel 21); and then fixes the PCB module to the housing assembly (or button panel 21) with screws 5.

[0065] It is understandable that PCB stands for Printed Circuit Board, which is the support structure for electronic components; while PCB module stands for Printed Circuit Board Assembly (PCBA), which is a circuit board with electronic components inserted or surface-mounted.

[0066] In some embodiments, such as Figure 6 and Figure 7 As shown, the light-blocking wall 124 has a preset first height dimension in the Z direction, and the switch 42 has a preset second height dimension in the Z direction.

[0067] It should be noted that the first height dimension is smaller than the second height dimension. This design allows the force-applying part 125 to limit the descent height of the switch 42 in the Z direction when the switch 42 is pressed, thereby preventing damage to the switch 42 due to violent pressing.

[0068] In some embodiments, such as Figure 1 , Figure 5 and Figure 7 As shown, the switch assembly 4 also includes an indicator light 43, which is located next to the switch 42.

[0069] It is understandable that since the light-shielding wall 124 is mounted on the switch 42 and is located around the switch 42 and the indicator light 43, the light-shielding wall 124 can prevent the light beam of the indicator light 43 from spreading to other areas and causing misjudgment when the indicator light 43 is lit. This shows that the light-shielding wall 124 also has the function of light shielding.

[0070] Furthermore, the indicator light 43 will only light up when the force part 125 presses the switch 42, and this design can determine whether the switch is working properly.

[0071] In electronic devices, the circuit system or functional modules are housed inside the housing assembly. Therefore, this combined push-button switch device can prevent the circuit system or functional modules housed inside the housing assembly from being damaged by dust or accidental water exposure.

[0072] In summary, the combined push-button switch device provided by this utility model connects multiple buttons to a support frame via elastic arms. This allows the buttons to be returned to their original positions via the elastic arms during use, effectively extending the service life of the combined push-button switch device. Furthermore, the support frame, multiple elastic arms, and multiple buttons are integrated into a single structure, making it less prone to errors or misalignments during assembly of multiple buttons, thus facilitating assembly. Additionally, the first protective wall abuts against the first inner surface, and the second protective wall is embedded within the first protective wall and abuts against the substrate. This design prevents dust from entering the internal circuitry of the combined push-button switch device and protects it from accidental water contact.

[0073] The above description, in conjunction with specific / preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and all of these fall within the protection scope of the present invention.
