Description

Technical Field

[0001] This utility model relates to the field of home appliances, and in particular to a touch button structure and a home appliance product. Background Technology

[0002] In home appliance design, curved surfaces have become an important trend for improving aesthetics and user experience. However, when traditional touch buttons are applied to curved or non-planar structures, the button's appearance also needs to be curved. This makes the traditional touch button structure unsuitable for triggering the PCB board, or results in poor PCB board triggering, affecting the accuracy and reliability of user operation. Therefore, improvements are needed to address this deficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a touch button structure and home appliance product to address the problem that traditional touch button structures are no longer suitable for triggering PCB boards or have poor triggering effects on products with curved or non-planar appearances, which affects the accuracy and reliability of user operation.

[0004] A touch button structure includes: a touch component; a PCB board assembly disposed opposite to the touch component; a trigger rod disposed on the touch component and located on the side of the touch component facing the PCB board assembly, the trigger rod extending toward the PCB board assembly; the trigger rod abuts against the PCB board assembly, the trigger rod being capable of applying a force F to the PCB board assembly at least once, the PCB board assembly outputting a first control signal when the trigger rod applies a force F to the PCB board assembly once, and the PCB board assembly outputting a second control signal when the trigger rod applies a force F to the PCB board assembly a second time; or, the trigger rod is capable of abutting or separating from the PCB board assembly, the PCB board assembly outputting a first control signal when the trigger rod abuts against the PCB board assembly once, and the PCB board assembly outputting a second control signal when the trigger rod abuts against the PCB board assembly a second time.

[0005] The first aspect of this application discloses a touch button structure that facilitates user touch operation and enables convenient control of product functions through the placement of the touch component. When the touch component is touched, the force applied to it is directly transmitted to the PCB board assembly via a trigger rod, thereby triggering control signals. These signals, such as a first control signal and a second control signal, can be switch signals or function start / stop signals. By using a trigger rod instead of traditional structures like springs, the design can accommodate touch button structures with curved or non-planar surfaces, resulting in better triggering of the PCB board assembly. This design does not affect the overall sensitivity of the touch button structure and is suitable for installation on products with curved or non-planar surfaces, offering good accuracy and reliability. The trigger rod can be in constant contact with the PCB board assembly; alternatively, it can be in contact with the PCB board assembly only when a control signal is needed and detached when not needed. Furthermore, only a small portion of the trigger rod connects to the inner wall of the touch component, thus not affecting the uniformity and continuity of the adhesive application on the inner wall and preventing injection molding defects caused by poor adhesive flow due to localized thickening of the adhesive application area.

[0006] In one embodiment, the touch component has a C-shaped or arc-shaped cross-section. This C-shaped or arc-shaped cross-section allows the touch component to perfectly conform to the curved or non-planar appearance of the product, ensuring a seamless connection between the touch component and the product surface and enhancing the overall aesthetics. Furthermore, the arc or C-shaped cross-section makes the force on the touch component more even, ensuring that the force is stably transmitted to the PCB board assembly via the trigger rod regardless of the pressed location, guaranteeing the reliability of the touch response.

[0007] In one embodiment, the trigger lever and the touch component are integrated. This integration eliminates assembly gaps caused by separate structures, preventing loosening or poor contact due to long-term use and ensuring the stability of touch signal transmission. This design improves the sensitivity and accuracy of touch response.

[0008] In one embodiment, the trigger rod has an annular cross-section. This annular cross-section allows the trigger rod to be formed from concentric hollow rods. This design significantly reduces the amount of solid material used while maintaining mechanical strength, saving on material purchasing and management costs, and achieving lightweight and low-cost production. Furthermore, it ensures that force is evenly transmitted to the PCB assembly, guaranteeing stable output of the control signal.

[0009] In one embodiment, the end face of the trigger rod abuts against the PCB board assembly, and the horizontal plane of the end face of the trigger rod abutting against the PCB board assembly is parallel to the horizontal plane of the PCB board assembly. By ensuring that the horizontal plane of the end face of the trigger rod abutting against the PCB board assembly is parallel to the horizontal plane of the PCB board assembly, the end face of the trigger rod is flat, effectively increasing the contact area between the trigger rod and the PCB board assembly, achieving uniform force transmission, and ensuring stable output of the control signal.

[0010] In one embodiment, the trigger lever includes a first trigger post and a second trigger post, both of which are disposed on the touch component. Both the first and second trigger posts extend toward the PCB board assembly and abut against it. The second trigger post surrounds the first trigger post. The arrangement of the first and second trigger posts enables uniform force transmission, thereby stably achieving uniform signal transmission from the PCB board assembly. Furthermore, the arrangement of the second trigger post surrounding the first trigger post reduces the material required for solid structures, saving on material purchase and management costs.

[0011] In one embodiment, a third trigger post is further included. The third trigger post is disposed on the touch component, extends towards the PCB board assembly, and abuts against the PCB board assembly. The third trigger post surrounds the second trigger post. The placement of the third trigger post increases the contact area between the trigger component and the PCB board assembly, thereby applying force more evenly to the PCB board assembly, enabling the PCB board assembly to output control signals more stably. Furthermore, by surrounding the second trigger post, the material required for a solid structure can be reduced, saving on material purchase and management costs.

[0012] In one embodiment, the first, second, and third trigger pillars are all tubular. This tubular, hollow structure ensures mechanical strength while significantly reducing overall weight, facilitating lightweight product design. Even if one of the three trigger pillars fails, the other two will remain functional, effectively extending the product's lifespan. Furthermore, compared to solid pillars, this significantly reduces material consumption and production costs while maintaining sufficient structural rigidity.

[0013] In one embodiment, the first, second, and third trigger pillars are coaxially arranged. By coaxially arranging the first, second, and third trigger pillars, material consumption can be significantly reduced compared to solid pillars, lowering production costs while maintaining sufficient structural rigidity. Furthermore, it avoids localized stress concentrations, ensuring stable output of the control signal.

[0014] In one embodiment, a reinforcing rib is further included. The reinforcing rib is connected to the first trigger post, the second trigger post, and the third trigger post, respectively, and is located between the first trigger post and the third trigger post. By connecting the reinforcing rib to the first, second, and third trigger posts, the structural strength can be improved, significantly enhancing the overall structure's resistance to deformation and ensuring shape stability under frequent pressing. Furthermore, the reinforcing rib improves the uniformity of force distribution.

[0015] In one embodiment, there are multiple reinforcing ribs, each connected to the first, second, and third trigger posts. These reinforcing ribs are spaced apart circumferentially along the third trigger post and are located between the first and third trigger posts. By connecting multiple reinforcing ribs to the first, second, and third trigger posts, the overall rigidity of the product is significantly improved, localized deformation is avoided, and the overall resistance to deformation is enhanced.

[0016] In one embodiment, the two ends of the reinforcing rib abut against the touch component and the PCB board assembly, respectively. By abutting the two ends of the reinforcing rib against the touch component and the PCB board assembly, the force can also be transmitted to the PCB board assembly, increasing the contact area between the trigger rod and the PCB board assembly. This allows the force to be transmitted more evenly to the PCB board assembly, ensuring stable output of the control signal from the PCB board assembly.

[0017] In one embodiment, the two sides of the reinforcing rib are connected to the first trigger post and the third trigger post, respectively. By connecting the two sides of the reinforcing rib to the first trigger post and the third trigger post, the strength and deformation resistance of the overall structure can be improved.

[0018] In one embodiment, the PCB assembly includes a substrate and a touch pad. The substrate is disposed on an external component, and the touch pad is disposed on the substrate. A trigger rod abuts against the touch pad, and the trigger rod is capable of applying a force F to the touch pad. When the trigger rod applies force F to the touch pad once, the PCB assembly outputs a first control signal; when the trigger rod applies force F to the touch pad a second time, the PCB assembly outputs a second control signal. Alternatively, the trigger rod is disposed opposite to the touch pad, and the trigger rod can abut or separate from the touch pad. When the trigger rod abuts against the touch pad once, the PCB assembly outputs a first control signal; when the trigger rod abuts against the touch pad a second time, the PCB assembly outputs a second control signal. As the core sensing unit on the PCB assembly, the touch pad converts the mechanical force transmitted by the trigger rod into an electrical signal, achieving a precise conversion from physical pressure to electronic commands.

[0019] In one embodiment, an elastic element is further included, which is sleeved on the trigger rod, with its two ends abutting against the touch component and the PCB board assembly, respectively. This design, where the two ends of the elastic element abut against the touch component and the PCB board assembly, is particularly suitable for situations where the trigger rod can be separated from the PCB board assembly, allowing a force to be applied to the touch component, causing it to automatically reset.

[0020] A home appliance product includes: the aforementioned touch button structure.

[0021] The second aspect of this application discloses a home appliance product whose touch button structure can perfectly match the curved or non-planar surfaces of the product, solving the problems of difficult installation and unresponsive touch control of traditional buttons on non-planar structures. This design enables the triggering of control signals from PCB board components to achieve basic operations such as switching on / off and function activation / deactivation, with high precision and reliability.

[0036] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0038] Example 1

[0039] like Figure 1-10As shown, this embodiment discloses a touch button structure, including: a touch component 1; a PCB board assembly 2, the PCB board assembly 2 being disposed opposite to the touch component 1; a trigger rod 3, the trigger rod 3 being disposed on the touch component 1 and located on the side of the touch component 1 facing the PCB board assembly 2, the trigger rod 3 extending towards the PCB board assembly 2; the trigger rod 3 abutting against the PCB board assembly 2, the trigger rod 3 being capable of applying a force F to the PCB board assembly 2 at least once, the PCB board assembly 2 outputting a first control signal when the trigger rod 3 applies a force F to the PCB board assembly 2 once, and the PCB board assembly 2 outputting a second control signal when the trigger rod 3 applies a force F to the PCB board assembly 2 a second time; or, the trigger rod 3 being capable of abutting or separating from the PCB board assembly 2, the PCB board assembly 2 outputting a first control signal when the trigger rod 3 abuts against the PCB board assembly 2 once, and the PCB board assembly 2 outputting a second control signal when the trigger rod 3 abuts against the PCB board assembly 2 a second time.

[0040] The first aspect of this application discloses a touch button structure. The touch component 1 facilitates user touch operation and enables easy control of product functions. Touching the touch component 1 allows the force applied to it to be directly transmitted to the PCB board assembly 2 via a trigger rod 3, triggering control signals. These signals can be switch signals or function start / stop signals. The use of a trigger rod 3 instead of traditional structures like springs allows for operation on curved or non-planar touch button structures, resulting in better triggering of the PCB board assembly 2. This design does not affect the overall sensitivity of the touch button structure and is suitable for installation on products with curved or non-planar surfaces, offering good accuracy and reliability. The trigger rod 3 can be in constant contact with the PCB board assembly 2; or it can be in contact with the PCB board assembly 2 only when a control signal is needed and disconnected when not needed. Furthermore, only a small portion of the trigger rod 3 connects to the inner wall of the touch component 1, preventing interference with the uniformity and continuity of the adhesive application and avoiding injection molding defects caused by localized thickening of the adhesive.

[0041] like Figure 1-2 and Figure 5-7As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-section of the touch component 1 is C-shaped or arc-shaped. By using a C-shaped or arc-shaped cross-section, the touch component 1 can perfectly conform to the curved or non-planar appearance of the product, ensuring a seamless connection between the touch component 1 and the product surface and improving the overall aesthetics. Furthermore, the arc-shaped or C-shaped cross-section makes the force on the touch component 1 more even, ensuring that the force is stably transmitted to the PCB board assembly 2 through the trigger rod 3 regardless of the pressed position, thus guaranteeing the reliability of the touch response.

[0042] like Figure 5 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the trigger lever 3 and the touch component 1 are integrated. By integrating the trigger lever 3 and the touch component 1, assembly gaps caused by separate structures can be eliminated, avoiding loosening or poor contact problems due to long-term use, and ensuring the stability of touch signal transmission. This design can improve the sensitivity and accuracy of touch response.

[0043] like Figure 3-4 and Figure 7-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-section of the trigger rod 3 is annular. The trigger rod 3 has an annular cross-section; for example, it can be formed by concentric hollow rods. This design significantly reduces the amount of solid material used while ensuring mechanical strength, saving material purchase and management costs, and achieving lightweight and low-cost production. Furthermore, it allows for uniform force transmission to the PCB assembly 2, ensuring stable output of the control signal.

[0044] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the end face of the trigger rod 3 abuts against the PCB board assembly 2, and the horizontal plane of the end face of the trigger rod 3 abutting against the PCB board assembly 2 is parallel to the horizontal plane of the PCB board assembly 2. By ensuring that the horizontal plane of the end face of the trigger rod 3 abutting against the PCB board assembly 2 is parallel to the horizontal plane of the PCB board assembly 2, the end face of the trigger rod 3 is flat, which effectively increases the contact area between the trigger rod 3 and the PCB board assembly 2, achieving uniform force transmission and ensuring stable output of the control signal.

[0045] like Figure 3-4 and Figure 7-9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the trigger rod 3 includes a first trigger post 31 and a second trigger post 32, both of which are disposed on the touch component 1, both extending toward the PCB board assembly 2, both abutting against the PCB board assembly 2, and the second trigger post 32 surrounding the first trigger post 31. The arrangement of the first trigger post 31 and the second trigger post 32 enables uniform force transmission, thereby stably achieving uniform signal transmission of the PCB board assembly 2. The arrangement of the second trigger post 32 surrounding the first trigger post 31 reduces the material required for solid structures, saving material purchase and management costs.

[0046] like Figure 3-4 and Figure 7-9 As shown, in addition to the features of the above embodiments, this embodiment further includes a third trigger post 33, which is disposed on the touch component 1, extends toward the PCB board assembly 2, abuts against the PCB board assembly 2, and surrounds the second trigger post 32. The arrangement of the third trigger post 33 increases the contact area between the trigger component and the PCB board assembly 2, thereby applying force more evenly to the PCB board assembly 2, enabling the PCB board assembly 2 to output control signals more stably. Furthermore, by surrounding the second trigger post 32 with the third trigger post 33, the material of the solid structure can be reduced, saving material purchase and management costs.

[0047] like Figure 3-4 and Figure 7-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the first trigger column 31, the second trigger column 32, and the third trigger column 33 are all tubular. By making the first trigger column 31, the second trigger column 32, and the third trigger column 33 all tubular, the hollow tubular structure significantly reduces the overall weight while ensuring mechanical strength, which is beneficial for lightweight product design. Even if one of the three trigger columns fails, it will not affect the use of the other two trigger columns, effectively extending the product's service life. Moreover, compared to solid columns, it can significantly reduce material consumption, lower production costs, while maintaining sufficient structural rigidity.

[0048] like Figure 3-4 and Figure 7-9As shown, in addition to the features of the above embodiments, this embodiment further specifies that the first trigger column 31, the second trigger column 32, and the third trigger column 33 are coaxially arranged. By coaxially arranging the first trigger column 31, the second trigger column 32, and the third trigger column 33, material consumption can be significantly reduced compared to solid columns, lowering production costs while maintaining sufficient structural rigidity. Furthermore, it avoids localized stress concentration, ensuring stable output of the control signal.

[0049] like Figure 3-4 and Figure 7-9 As shown, in addition to the features of the above embodiments, this embodiment further includes a reinforcing rib 34, which is connected to the first trigger post 31, the second trigger post 32, and the third trigger post 33, respectively, and is located between the first trigger post 31 and the third trigger post 33. By connecting the reinforcing rib 34 to the first trigger post 31, the second trigger post 32, and the third trigger post 33, the structural strength can be improved, significantly enhancing the overall structure's resistance to deformation and ensuring shape stability under frequent pressing. Furthermore, the reinforcing rib 34 improves the uniformity of force distribution.

[0050] like Figure 3-4 and Figure 7-9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of reinforcing ribs 34 is multiple, and each of the multiple reinforcing ribs 34 is connected to the first trigger post 31, the second trigger post 32, and the third trigger post 33. The multiple reinforcing ribs 34 are spaced apart circumferentially along the third trigger post 33, and each of the multiple reinforcing ribs 34 is located between the first trigger post 31 and the third trigger post 33. By connecting multiple reinforcing ribs 34 to the first trigger post 31, the second trigger post 32, and the third trigger post 33, the overall rigidity of the product is significantly improved, local deformation is avoided, and the overall resistance to deformation is enhanced.

[0051] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the two ends of the reinforcing rib 34 abut against the touch component 1 and the PCB board assembly 2, respectively. By having the two ends of the reinforcing rib 34 abut against the touch component 1 and the PCB board assembly 2, the force can also be transmitted to the PCB board assembly 2 along with the reinforcing rib 34, increasing the contact area between the trigger rod 3 and the PCB board assembly 2. This allows the force to be transmitted more evenly to the PCB board assembly 2, ensuring stable output of the control signal from the PCB board assembly 2.

[0052] like Figure 3-4 and Figure 7-9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the two sides of the reinforcing rib 34 are respectively connected to the first trigger post 31 and the third trigger post 33. By connecting the two sides of the reinforcing rib 34 to the first trigger post 31 and the third trigger post 33 respectively, the strength and deformation resistance of the overall structure can be improved.

[0053] like Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further defines: the PCB board assembly 2 includes a substrate 21 and a touch pad 22, the substrate 21 is disposed on an external component, and the touch pad 22 is disposed on the substrate 21; the trigger rod 3 abuts against the touch pad 22, the trigger rod 3 is capable of applying a force F to the touch pad 22 at least once, the PCB board assembly 2 outputs a first control signal when the trigger rod 3 applies a force F to the touch pad 22 once, and the PCB board assembly 2 outputs a second control signal when the trigger rod 3 applies a force F to the touch pad 22 a second time; or, the trigger rod 3 is disposed opposite to the touch pad 22, the trigger rod 3 is capable of abutting or separating from the touch pad 22, the PCB board assembly 2 outputs a first control signal when the trigger rod 3 abuts against the touch pad 22 once, and the PCB board assembly 2 outputs a second control signal when the trigger rod 3 abuts against the touch pad 22 a second time. As the core sensing unit on the PCB board assembly 2, the touch pad 22 converts the mechanical force transmitted by the trigger rod 3 into an electrical signal, realizing the precise conversion from physical pressing to electronic command.

[0054] In addition to the features of the above embodiments, this embodiment further includes an elastic element, which is sleeved on the trigger rod 3, with its two ends abutting against the touch component 1 and the PCB board assembly 2, respectively. This design, where the two ends of the elastic element abut against the touch component 1 and the PCB board assembly 2, is particularly suitable for situations where the trigger rod 3 can be separated from the PCB board assembly 2, allowing a force to be applied to the touch component 1, causing it to automatically reset.
