Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories, and in particular to a protective case for electronic devices. Background Technology

[0002] Existing electronic device protective cases consist of a housing and buttons attached to the housing. Taking a mobile phone case as an example, the button is generally located in the position of the volume button and power button on the corresponding electronic device. When the user presses the button, the button applies force to the corresponding electronic device button on the phone, thereby pressing the corresponding electronic device button.

[0003] Since buttons on electronic devices are generally elongated, and the buttons on protective cases are also elongated, users need to press the middle of the button to ensure balanced force. However, through extensive research and testing, the applicant found that in actual use, users often cannot accurately press the middle of the button. Instead, due to habit or comfort, they tend to press the same end along the length for extended periods. This results in the button being stressed on only one end along its length over a long period. This uneven force distribution accelerates the wear and aging of the button's internal structure, rapidly shortening its lifespan. Utility Model Content

[0037] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of buttons in existing electronic devices and buttons on protective cases for electronic devices. Addressing the issue that current electronic device buttons (1) experience significant lifespan degradation during use and are prone to poor contact or malfunction after prolonged use, the inventors analyzed the problem and found that existing electronic device buttons typically consist of a button portion and an internal structure. Pressing the button portion causes the internal structure to move, transmitting force to contacts on the internal circuit board. Pressing the left side of the button activates a linkage on the left, while pressing the right side activates a linkage on the right. Pressing the middle of the button causes both linkages to move simultaneously.

[0038] However, existing electronic device buttons 1 are generally elongated. Based on the above analysis, it is known that only by pressing the middle position of button 1 can the left and right linkages be ensured to receive balanced force. In actual use, due to usage habits, pressing comfort, button position, and other factors, the right end of button 1 is often closer to the user's hand when holding the electronic device. This makes users more inclined to press the right end, easily leading to the right linkage structure being in a state of continuous operation, while the left linkage structure is almost inactive. Over time, this causes wear and aging of the right linkage, while the left linkage remains untouched. After a period of use, pressing the right end of button 1 will no longer function properly, while pressing the middle or left side will, affecting the user experience. Furthermore, the button's lifespan is rapidly shortened due to uneven force distribution.

[0039] Based on this, the inventor designed a protective case for electronic devices. When the buttons of an electronic device are pressed using this protective case, the case can concentrate the force on the buttons in the middle, reducing the risk of button malfunction.

[0040] Example 1

[0041] Please see Figures 2-5 , Figure 2 This is a schematic diagram of the structure of the electronic device protective case according to Embodiment 1 of this utility model. Figure 3 for Figure 2 A cross-sectional view along the AA direction. Figure 4 This is a schematic diagram of the button structure of the electronic device protective case according to Embodiment 1 of this utility model, and the electronic device button structure. Figure 5 This is a schematic diagram of the button structure of the electronic device protective case according to Embodiment 1 of the present invention. The electronic device protective case includes a housing 10 and a button 20 disposed on the housing 10. The button 20 includes a first part 21, a middle part 22, and a second part 23 in sequence. The first part 21 is connected to the housing 10, and the second part 23 is spaced apart from the housing 10. The middle part 22 has an inner surface 221 and an outer surface 222 opposite to the inner surface 221. The button 20 also includes a contact portion disposed on the inner surface 221. The contact portion is used to contact the electronic device button to operate the electronic device button. The contact portion ensures that when the button 20 is pressed, the force is transmitted to the electronic device button only through the contact portion. Since the contact portion is disposed on the inner surface 221 of the middle part 22, the force is ultimately transmitted to the middle position of the electronic device button through the contact portion, regardless of which part of the button 20 is pressed during use. At this time, the two ends of the connecting rod inside the electronic device button are evenly stressed, and the two ends of the connecting rod work simultaneously. This prevents damage to one end of the connecting rod structure due to uneven stress on the connecting rod, thus improving the button's lifespan.

[0042] Please see Figure 6 , Figure 6 This is a partial schematic diagram of the button of the electronic device protective case according to Embodiment 1 of this utility model. The second part 23 has an inner surface 231 and an outer surface 232. The inner surface 221 of the middle part 22 is set as a plane, which serves as the contact part. The inner surface 231 of the second part 23 is provided with a first inclined surface, and the first inclined surface slopes from the end of the second part 23 near the middle part 22 toward the outer surface 232 of the second part 23. The entire inner surface 231 of the second part 23 can be set as an inclined surface, or only a portion of the inner surface 231 of the second part 23 away from the middle part 22 can be set as an inclined surface. Preferably, setting the entire inner surface 231 as an inclined surface ensures that the force is concentrated in the middle position of the electronic device button; while setting a portion of the inner surface 231 as an inclined surface can concentrate the force as much as possible towards the middle position.

[0043] During use, the design of the first inclined surface makes the gap between the second part 23 and the electronic device button much larger than the gap between the middle part 22 and the electronic device button. When the second part 23 is pressed, due to the larger gap, the second part 23 needs to move a greater distance to contact the electronic device button. During this process, part of the force of pressing the second part 23 is transmitted to the middle part 22, causing the middle part 22 to also move. At this time, before the second part 23 contacts the electronic device button, the middle part 22 has already made contact with the electronic device button, and the force is transmitted to the electronic device button through the contact part. However, if the user presses the first part 21, since the end of the first part 21 away from the middle part 22 is connected to the housing 10, the force of pressing the first part 21 is more likely to move the end of the first part 21 closer to the middle part 22, thereby driving the middle part 22 to move. After moving a certain distance, the middle part 22 also makes contact with the electronic device button first. Therefore, in the above structure, no matter which part of the button 20 the user presses during use, the middle part 22 will contact the electronic device button first. The middle position of the electronic device button is subjected to force, which can play a good protective role for the internal structure of the electronic device button, balance the force, and thus improve the service life of the electronic device button.

[0044] Further, please refer to Figure 7 , Figure 7 This is a schematic diagram of the clearance portion of the electronic device protective case according to Embodiment 1 of this utility model. To ensure that when the first part 21 is pressed, the middle part 22 contacts the electronic device button first, a clearance portion can be provided on the inner surface of the first part 21. The button 20 also includes a clearance portion 25. The first part 21 has an inner surface 211 and an outer surface 212 opposite to the inner surface 211. The clearance portion 25 is disposed on the inner surface 211 of the first part 21. The clearance portion 25 is a recess disposed on the inner surface 211 of the first part 21, which increases the gap between the first part 21 and the electronic device button.

[0045] In another embodiment, a second inclined surface is provided on the inner surface 211 of the first portion 21, which serves as a clearance portion 25. The second inclined surface slopes from the end of the first portion 21 near the middle portion 22 toward the outer surface 212 of the first portion 21. Preferably, the first inclined surface and the second inclined surface are symmetrical to each other.

[0046] Furthermore, due to the first inclined surface, a height difference L1 exists between the inner surface 231 of the end of the second part 23 furthest from the middle part 21 and the inner surface of the middle part. This height difference L1 ensures sufficient clearance between the second part 23 and the electronic device button, preventing the second part 23 from contacting the electronic device button even when bent under force. The height difference L1 should be greater than or equal to 0.3 mm. Preferably, the height difference L1 should be controlled within the range of 0.7 mm to 0.8 mm.

[0047] Further, please refer to Figure 8 , Figure 8 This is a schematic diagram of the first inclined surface of the electronic device protective shell according to Embodiment 1 of this utility model. Different height differences L1 are set for different function buttons of the electronic device. For the volume buttons of the electronic device, the height difference L1 is set to 0.7mm; for the power button of the electronic device, the height difference L1 is set to 0.8mm.

[0048] Furthermore, the purpose of controlling the middle part 22 to contact the electronic device button first can also be achieved by controlling the angle A between the first inclined surface and the inner surface 221 of the middle part 22. The angle A should be controlled within the range of 1 degree to 10 degrees. Preferably, the angle A is set to 3.5 degrees.

[0049] Furthermore, to ensure that the center position of the electronic device button receives force, the starting point B of the first inclined surface is set within a range from 0.5mm offset from the midpoint C along the length of the button 20 towards the end of the second part 23 closer to the middle part 22 to 1.0mm offset from the end of the second part 23 away from the middle part 22. In this case, regardless of which part of the button 20 is pressed, the center position of the electronic device button receives force, while also providing the user with a good pressing feel. Preferably, setting the starting point B of the first inclined surface within a range from 0.5mm offset from the midpoint C along the length of the button 20 towards the end of the second part 23 closer to the middle part 22 to 0.5mm offset from the end of the second part 23 away from the middle part 22 provides even better performance and user experience.

[0050] Example 2

[0051] Please see Figure 9 , Figure 9This is a schematic diagram of the button structure of the electronic device protective case according to Embodiment 2 of this utility model. The structure of the electronic device protective case in this embodiment is basically the same as that in Embodiment 1, except that the contact portion of the original button 20 is replaced by a protrusion 24 on the inner surface 221 of the middle portion 22. This protrusion 24 is higher than the inner surface 231 of the second portion 23 and also higher than the inner surface 211 of the first portion 21. By providing the protrusion 24, when the second portion 23 is pressed, although the movement of the second portion 23 is faster than the movement of the middle portion 22, the middle portion 22 only needs to move a small amount to make the protrusion 24 contact the electronic device button. At this time, the second portion 23 is not in contact with the electronic device button, so the force can be transmitted to the middle position of the electronic device button through the protrusion 24.

[0052] Furthermore, to ensure that the protrusion 24 can transmit force to the middle position of the electronic device button, the protrusion 24 is positioned within a range from 0.5 mm away from the first part 21 and 1.0 mm away from the second part 23 at the midpoint C of the button 20 in the length direction.

[0053] Example 3

[0054] Please see Figure 10 , Figure 10 This is a schematic diagram of the protrusion structure of the electronic device protective case according to Embodiment 3 of this utility model. The structure of the electronic device protective case in this embodiment is basically the same as that in Embodiment 1, except that a protrusion 24 is provided on the original first inclined surface. Furthermore, the protrusion 24 is not only located on the inner surface 221 of the middle portion 22, but extends from the inner surface 221 of the middle portion 22 to the inner surface 231 of the second portion 23. Since the inner surface 221 of the middle portion 22 is a plane and the inner surface 231 of the second portion 23 is a first inclined surface, by controlling the height of the protrusion 24 to be consistent, the protrusion 24 of the middle portion 22 is closer to the electronic device button. When the second portion 23 is pressed, the protrusion 24 of the middle portion 22 contacts the electronic device button first.

[0055] The protrusion 24 is ring-shaped and is positioned on the inner surface of the button 20 and close to the side wall of the button 20. The protrusion 24 can ensure that when the button 20 is pressed, the force is transmitted to the middle position of the electronic device button, and at the same time, it can also strengthen the button 20.

[0056] In another embodiment, the protrusion 24 may not be set as a ring, but instead as a strip along the length of the button 20. The strip-shaped protrusion 24 may be a single piece or multiple pieces spaced apart.

[0057] Example 4

[0058] The electronic device protective case provided in this embodiment has a structure that is basically the same as that in Embodiment 1, except that a protrusion 24 is provided on the original first inclined surface. The protrusion 24 extends from the inner surface 221 of the middle part 22 to the inner surface 231 of the second part 23. The protrusion 24 is made of a wear-resistant material. Since the button 20 will come into contact with the electronic device button and generate friction when pressed, the use of a wear-resistant material can effectively improve the strength of the button, ensuring that the height of the protrusion 24 will not be insufficient due to wear after repeated use, thus improving the transmission of influence.

[0059] Further, please refer to Figure 11-12 , Figure 11 This is a partial structural diagram of the buttons and button mounting holes of the electronic device protective case according to Embodiment 4 of this utility model. Figure 12 This is a partial structural diagram of the button and housing of the electronic device protective case according to Embodiment 4 of this utility model. This embodiment also provides a connection structure between the button 20 and the housing 10, used to connect the button 20 to the housing 10. The housing 10 is provided with a button mounting hole 101, and the button 20 is disposed within the button mounting hole 101. The end of the first portion 21 away from the middle portion 22 is connected to the side wall of the button mounting hole 101. Meanwhile, to ensure that the user can touch and press the button 20, the outer surface of the button 20 is higher than the edge 101A of the button mounting hole 101, and the height of the higher surface ranges from 0.4mm to 0.8mm. Preferably, the height of the outer surface of the button 20 above the edge 101A of the button mounting hole 101 is 0.7mm, so that the contact area between the user's finger and the button is sufficiently large, resulting in a better pressing feel.

[0060] Further, see Figure 13 , Figure 13This is a schematic diagram of the elastic part and button structure of the electronic device protective shell according to Embodiment 4 of this utility model. The shell 10 further includes an elastic part 102 disposed on the side wall of the button mounting hole 101. The end of the first part 21 away from the middle part 22 is connected to the side wall of the button mounting hole 101 through the elastic part 102. To ensure good elasticity, the thickness H2 of the elastic part 102 is limited to 0.4mm to 0.8mm. This thickness of the elastic part 102 provides good elasticity and connection strength. If the thickness is less than the thickness range H2, the connection strength is insufficient; if the thickness is greater than the thickness range H2, the elasticity deteriorates. Preferably, the thickness of the elastic part 102 is set to 0.6mm. Furthermore, the elastic part 102 enables the button to rebound after the external force is removed, and the rebound force of the elastic part 102 is in the range of 2N to 5N.

[0061] Furthermore, regarding the button force (pressing force and rebound force) of the button 20 of the electronic device protective shell of this utility model, the applicant conducted experiments to measure the data, and the measurement results are as follows:

[0062]

[0063] The button force refers to the force required to press the button and the force required for the button to rebound. "Real iPhone 15" refers to pressing different buttons (volume +, volume -, and power buttons) on an iPhone 15 and measuring the different forces required. "New button" refers to the button structure on the protective case using the technology of this application, while "old button" refers to the button structure on existing protective cases. The measurement data shows that the button structure of button 20 on the electronic device protective case using this invention has a pressing and rebound force within the range of 2N to 5N. Furthermore, its pressing and rebound forces are closer to those of the buttons on a real device, making the button movement smoother and eliminating any damping sensation when pressed.

[0064] Furthermore, the elastic portion 102 extends along the sidewall of the button mounting hole 101, and the elastic portion 102 is generally fan-shaped, wherein the central angle of the fan shape is greater than 0 degrees and less than or equal to 180 degrees. Preferably, the angle of the fan shape is 160 degrees. Limiting the fan shape angle within this range can both ensure the connection strength between the button 20 and the sidewall of the button mounting hole 101 and provide better rebound force.

[0065] After the button 20 is disposed in the button mounting hole 101, the end of the first inclined surface away from the middle portion 22 is lower than the edge 101A of the button mounting hole 101, and the height difference between the first inclined surface and the edge 101A of the button mounting hole 101 is greater than or equal to 0.1mm. Preferably, the end of the first inclined surface away from the middle portion 22 is 0.2mm lower than the edge 101A of the button mounting hole 101.

[0066] Furthermore, the button 20 deforms when pressed. Since the first part 21 and the second part 23 need to be designed to prevent them from contacting the electronic device's buttons first, the thickness of the button 20 is subject to certain requirements. In this embodiment, the thickness H1 of the button 20 needs to be in the range of 1mm to 2.5mm to ensure that structures such as bevels and / or clearances can be provided on the first part 21 and the second part 23. Preferably, the thickness H1 of the button 20 is 1.75mm.

[0067] To ensure that the button 20 can move within the button mounting hole 101 without interference, except for the portion 21 connected to the side wall of the button mounting hole 101, the other parts of the button 20 are spaced apart from the side wall of the button mounting hole 101, with a spacing L2 greater than or equal to 0.3 mm. This ensures that the button 20 will not interfere with the side wall of the button mounting hole 101 when it moves. Preferably, the spacing L2 is 1 mm, which ensures sufficient safe distance for the button 20 to move, while also preventing the spacing from being too large and allowing dust to enter.

[0068] Compared to existing technologies, the electronic device protective case of this utility model has a contact part set on the inner surface of the middle part of the button on the case. When the user presses the button, the contact part contacts the button of the electronic device to operate the electronic device. Since the contact part is set in the middle part of the button, it also corresponds to the middle position of the button. Therefore, no matter which area of ​​the outer surface of the button is pressed during use, the pressing force will only be transmitted to the middle position of the button through the contact part. At this time, the button of the electronic device is under balanced force, and the wear and aging of the internal structure of the button of the electronic device is controlled, which can effectively reduce the occurrence of function key failure, and there is no need to add more complex structures.
