[0030] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral 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; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] This utility model proposes a touch-activated zoom button structure and an electronic device protective shell, which is located in the button slot inside the shell 1.

[0033] Reference Figures 1 to 7 In this embodiment, it includes:

[0034] A soft rubber structure 2 is provided in the button slot, and a card slot 23 is provided inside the soft rubber structure 2;

[0035] The hard plastic button 3 is disposed in the slot 23. The hard plastic button 3 includes a pressing part 31, a shaft part 32 extending from one side of the pressing part 31, and an actuating part 33. The shaft part 32 is disposed between the pressing part 31 and the actuating part 33. The actuating part 33 is used to trigger a pressing signal. The upper and lower ends of the hard plastic button 3 are provided with receiving grooves 34.

[0036] The conductive silicone strip 4 is fixedly disposed in the receiving groove 34, and the conductive silicone strip 4 is used to electrically connect with the capacitive sensing part of the device.

[0037] Optionally, in this embodiment, the touch-activated zoom button structure is disposed in the button slot within the housing 1, and the touch-activated zoom button structure includes a soft rubber structure 2, a hard rubber button 3, and a conductive silicone strip 4. The soft rubber structure 2 is disposed in the button slot, and a slot 23 is provided within the soft rubber structure 2; the hard rubber button 3 is disposed in the slot 23, and the hard rubber button 3 includes a pressing part 31, a shaft part 32 extending from one side of the pressing part 31, and a trigger part 33. The shaft part 32 is disposed between the pressing part 31 and the trigger part 33. The pressing part 31, the shaft part 32, and the trigger part 33 are integrally formed, which facilitates processing and molding. By pressing the pressing part 31, the pressing signal is transmitted to the trigger part 33 through the shaft part 32, and the trigger part 33 is used to trigger the pressing signal; receiving grooves 34 are provided through the upper and lower ends of the hard rubber button 3, and the conductive silicone strip 4 is fixedly disposed in the receiving grooves 34, and the conductive silicone strip 4 is fixedly disposed in the receiving grooves 34. The silicone strip 4 is used to electrically connect to the capacitive sensing part of the device. When the operator presses the pressing part 31, the shaft 32 transmits pressure, the actuating part 33 triggers the pressing signal, and simultaneously moves the conductive silicone strip 4 to contact the capacitive sensing part of the device. Because the conductive silicone strip 4 is conductive, it detects the capacitance change caused by human touch to achieve the corresponding operation, i.e., touch wake-up or zoom. The soft silicone structure provides a certain buffer for the hard silicone buttons, preventing excessive pressure between the hard silicone buttons and the device buttons from causing damage. Compared to conventional conductive metal strips, the conductive silicone strip 4 has lower hardness and a certain degree of flexibility, allowing for better contact with the buttons while avoiding direct contact that could damage them. It also maintains elasticity and a good feel even after long-term use, and is relatively inexpensive. Through the above component setup, touch wake-up and zoom of the electronic device are achieved. The button structure has good flexibility and conductivity, allowing for better contact with the device buttons, reducing the risk of button damage, and is cost-effective.

[0038] In this embodiment, an annular groove is formed around the outer side of the pressing part, the outer side of the shaft part, and the outer side of the touching part. The soft rubber structure is snapped into the annular groove, and the snap-fit ​​connection between the soft rubber structure and the annular inner groove ensures a tight connection. Further, the soft rubber structure includes a connecting section 21, an elastic section 22, and a mounting section 23. The elastic section 22 is located between the connecting section 21 and the mounting section 23. One end of the connecting section 21 is connected to the housing, and the other end is connected to the elastic section 22. The mounting section 23 is snapped into the annular inner groove. Since the height of the conductive silicone strip 4 is greater than the height of the touching part, when the device is installed inside the housing... The conductive silicone strip 4 is interference-fitted with the device button. When the device button pushes the conductive silicone strip 4 outward, the mounting section 23 engages with the annular groove, and the conductive silicone strip 4 is interference-fitted with the hard button. That is, when the conductive silicone strip 4 moves outward, the mounting section 23 drives the elastic section 22 to move, thereby causing the elastic section 22 to deform. The soft rubber structure is TPU soft rubber, which is a high-performance elastic material with high elasticity and wear resistance. Therefore, after the elastic section 22 deforms, it has a tendency to recover its deformation. The resulting recovery force allows the soft rubber structure and the conductive silicone strip 4 to fit tightly against the device button, resulting in a tight connection.

[0039] In this embodiment, the elastic segment 22 has a U-shaped cross-section and a thickness of 0.1 to 0.5 mm. This allows the U-shaped structure to have good elasticity without causing irreversible deformation due to its thickness. In other embodiments, the cross-section of the elastic segment 22 can also be V-shaped, which is not limited here. Furthermore, a step layer 24 is formed at the connection between the elastic segment 22 and the connecting segment 21. The step layer 24 is used to abut against the lower end face of the touch part, and the distance between the step layer 24 and the lower end face of the touch part is 0.1-0 to 0.2 mm. That is, the step layer 24 is used to limit the pressing distance of the hard rubber button to prevent the pressing distance from being too large, which would cause excessive pressing force and damage to the device button.

[0040] In this embodiment, the conductive silicone strip 4 includes a conductive segment 41 and an insulating segment 42. Multiple sets of conductive segments 41 and insulating segments 42 are provided, and the conductive segments 41 and insulating segments 42 are alternately stacked to form a complete conductive silicone strip 4. The thickness of the conductive segment 41 is 0.025-0.5mm, and the thickness of the insulating segment 42 is 0.025-0.5mm.

[0041] In this embodiment, the elastic segments 22 on the left and right sides of the soft rubber structure are cut through, that is, the elastic segments 22 at the top and bottom ends, together with the connecting segment 21 and the mounting segment 23, form a C-shaped groove 25. The elastic segments 22 on the left and right sides of the soft rubber structure are cut off, leaving only the elastic segments 22 at the top and bottom ends. By reducing the elastic segments 22 of the U-shaped structure, the restoring force generated by the U-shaped structure after being compressed and deformed is reduced, preventing the excessive restoring force from damaging the button or making the connection too tight.

[0042] In this example, a decorative piece 5 is provided at the upper end of the pressing part and the conductive silicone strip 4. The decorative piece 5 is made of PET sheet or glass sheet. Both PET sheet and glass sheet have high transparency, high strength and beautiful appearance. By setting a double-sided adhesive strip 6 between the decorative piece 5 and the conductive silicone strip 4, a tight connection between the decorative piece 5 and the conductive silicone strip 4 can be achieved, and the conductive silicone strip 4 can be isolated from contact with the external environment, thereby protecting the service life of the product.

[0043] This utility model also provides a protective case for an electronic device, which has the aforementioned touch-activated zoom button structure, thereby enabling better touch-activated zoom functionality. The electronic device protective case can be a phone case or a camera case. The button structure allows control of the touch-activated function of the electronic device housed within the case, and enables touch zoom, thus improving the user experience.

[0044] It should be noted that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereunder. Within the scope of the technology disclosed in this utility model, any changes, modifications, substitutions, combinations, or simplifications made by those skilled in the art without departing from the spirit and principle of this utility model shall be considered equivalent substitutions and shall be covered within the protection scope of this utility model.
