Description

Technical Field

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

[0002] Electronic devices have gradually become necessities in people's lives, such as mobile phones, tablets, and laptops. Taking mobile phones as an example, many users usually equip their mobile phones with protective cases after purchasing them to protect them.

[0003] Chinese patent CN222356419U discloses a button structure for a mobile phone case. Specifically, the inner circumferential surface of the button positioning hole of the mobile phone case is provided with a fitting groove, a sensor button is provided in the button positioning hole, and an annular flange is provided on the outer frame of the sensor button. The sensor button is mounted on the mobile phone case by fitting the annular flange into the fitting groove.

[0004] However, when the annular flange of the sensor key is fitted into the fitting groove, the side of the annular flange facing outward of the receiving space abuts against the side of the fitting groove facing inward of the receiving space, which can only limit the movement of the sensor key in the direction outward of the receiving space. When the protective case is not on the phone, the sensor key is easy to come out of the key positioning hole in the direction inward of the receiving space. Especially when the outside of the sensor key is subjected to pressure, the sensor key is more likely to come out of the key positioning hole, which can easily lead to the loss of the sensor key. Utility Model Content

[0005] This application discloses a button structure and a protective shell for electronic devices, which makes it difficult for the button structure to fall out of the button hole, whether facing inward or outward, effectively improving the stability of the button structure embedded in the button hole.

[0006] To achieve the above objectives, this application discloses a button structure for embedding in a button hole of a protective shell. The button hole has multiple spaced-apart mounting steps on its wall and a first latching portion disposed between two adjacent mounting steps. The button structure includes:

[0007] A conductive element having a conductive surface and an operating surface disposed opposite to each other along its thickness direction; the conductive surface is used to contact a button of an electronic device, and the operating surface is used to touch or press.

[0008] A connecting frame surrounds the conductive member. A second snap-fit ​​portion is provided on the side of the connecting frame away from the conductive member. The button structure is embedded in the button hole through the connecting frame, and the connecting frame is placed on the mounting step. The first snap-fit ​​portion and the second snap-fit ​​portion are engaged.

[0009] This application also discloses a protective case for electronic devices, comprising:

[0010] The protective frame includes multiple frame walls that form a receiving space for accommodating electronic devices. Each frame wall has a keyhole that extends through the frame wall along its thickness direction. The wall of the keyhole has multiple mounting steps arranged at intervals and a first latching part disposed between two adjacent mounting steps.

[0011] As described above, the button structure is embedded in the button hole through the connecting frame, and the connecting frame is placed on the mounting step, with the first snap-fit ​​part engaging with the second snap-fit ​​part.

[0012] This application also discloses another button structure, which is used to be embedded in the button hole of the protective shell. The button hole has an installation step on its wall. The button structure includes:

[0013] A conductive element having a conductive surface and an operating surface disposed opposite to each other along its thickness direction; the conductive surface is used to contact a button of an electronic device, and the operating surface is used to touch or press.

[0014] A connecting frame is provided around the conductive member. The connecting frame includes a first connecting frame and a second connecting frame that are fastened together. The button structure is embedded in the button hole through the first connecting frame and the second connecting frame that are fastened together, and the mounting step is sandwiched between the first connecting frame and the second connecting frame.

[0015] This application also discloses another protective case for electronic devices, including:

[0016] The protective frame includes multiple frame walls that form a receiving space for accommodating electronic devices. Each frame wall has a keyhole that extends through the frame wall along its thickness direction. The wall of the keyhole has multiple mounting steps arranged at intervals and a first latching part disposed between two adjacent mounting steps.

[0017] In another button structure described above, the button structure is embedded in the button hole by fastening together the first connecting frame and the second connecting frame, and the mounting step is sandwiched between the first connecting frame and the second connecting frame.

[0018] Compared with the prior art, this application has at least the following beneficial effects:

[0019] In this application, by setting an installation step on the wall of the key hole, the key structure is embedded in the key hole through a connecting frame, and the connecting frame is placed on the installation step. The key structure is engaged with the key hole wall through a snap-fit ​​structure, or the key structure itself is snapped to hold the installation step in place. This allows the key structure to be fixed relative to the protective frame along the thickness direction of the conductive component. When the key structure is embedded in the key hole, it is not easy for the key structure to fall out of the key hole, effectively improving the stability of the key structure installed in the key hole and avoiding the loss of the key structure due to it falling out of the key hole.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] In this invention, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0051] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0052] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0053] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0054] Chinese patent CN222356419U discloses a button structure for a mobile phone protective case, such as... Figure 1 As shown, the phone case has a key positioning hole, and the inner circumferential surface of the key positioning hole is recessed with a fitting groove 15. A sensor key 20 is installed in the key positioning hole. The outer frame 21 of the sensor key 20 is provided with an annular flange 211. The annular flange 211 is fitted into the fitting groove 15, so that the sensor key 20 is mounted on the phone case. The key body 24 and the washer 26 of the sensor key 20 abut against the touch button 2 of the phone 1. When the sensor key 20 is operated, the phone 1 can perform corresponding set actions and functions.

[0055] However, when the annular flange 211 of the aforementioned sensor key 20 is fitted into the fitting groove 15, the side of the annular flange 211 facing outward of the receiving space abuts against the side of the fitting groove facing inward of the receiving space. This can only limit the movement of the sensor key 20 outward of the receiving space. When the protective shell is not fitted onto the mobile phone 1, the key positioning hole cannot limit the movement of the sensor key 20 inward of the receiving space, which can easily cause the sensor key 20 to come out of the key positioning hole inward of the receiving space. Especially when the outside of the sensor key 20 is subjected to pressure, the sensor key 20 is more likely to come out of the key positioning hole, which can easily lead to the loss of the sensor key 20.

[0056] In view of this, the present invention provides a button structure and a protective shell for electronic devices, which makes it difficult for the button structure to come out of the button hole, whether facing inward or outward, thus effectively improving the stability of the button structure installed in the button hole.

[0057] The technical solution of this application will be described in detail below with reference to specific embodiments and accompanying drawings.

[0058] This application provides a button structure for use when embedded in the protective case of an electronic device, such as... Figures 2-6 As shown in the figure, the protective case 100 of the electronic device includes a protective frame 20 and a button structure 10. The protective frame 20 includes multiple frame walls 1, which form a receiving space 3 for accommodating the electronic device. The frame walls 1 are provided with button holes 2 that penetrate the frame walls 1 along the thickness direction. The walls of the button holes 2 are provided with multiple mounting steps 21 arranged at intervals and a first latching part 22 disposed between two adjacent mounting steps 21. The button structure 10 is embedded in the button holes 2 through a connecting frame 4, and the connecting frame 4 is placed on the mounting steps 21. The first latching part 22 is engaged with the second latching part 41.

[0059] Thus, a receiving space 3 for accommodating electronic devices is formed by multiple frame walls 1, so that when using the protective shell, the electronic devices can be placed in the receiving space to protect them.

[0060] The button structure 10 is embedded in the button hole 2 through the connecting frame 4, and the connecting frame 4 is placed on the mounting step 21 in the button hole 2. The first snap-fit ​​part 22 and the second snap-fit ​​part 41 in the button hole 2 are engaged, so that the button structure 10 can be stably embedded in the button hole 2. That is, the button structure 10 is not easy to come out of the button hole 2, whether it is facing inward or outward of the receiving space 3, which effectively improves the stability of the button structure 10 installed in the button hole 2.

[0061] In addition, the button structure 10 is embedded in the button hole 2 through the connecting frame 4, and the connecting frame 4 is placed on the mounting step 21 in the button hole 2. That is, during the process of embedding the button structure 10 into the button hole 2, the button structure 10 is pressed into the button hole 2 until the connecting frame 4 abuts against the mounting step 21. This can be considered as the button structure 10 being installed in place. This effectively prevents the button structure 10 from coming out of the button hole 2 in the pressing direction, while also facilitating the installation of the button structure 10.

[0062] like Figures 4-10 As shown, the aforementioned button structure 10 may include a conductive member 6 and a connecting frame 4. The conductive member 6 has a [missing information - likely a thickness direction] along its thickness direction (e.g., ...). Figure 4 The conductive surface 6b and the operating surface 6a are arranged opposite each other in the direction shown in x1. The conductive surface 6b is used to contact the button of the electronic device, and the operating surface 6a is used for touching or pressing. The connecting frame 4 surrounds the conductive member 6. The side of the connecting frame 4 away from the conductive member 6 is provided with a second buckling part 41. The button structure 10 is embedded in the button hole 2 through the connecting frame 4, and the connecting frame 4 is placed on the mounting step 21. The first buckling part 22 is engaged with the second buckling part 41.

[0063] Thus, the conductive member 6 has a conductive surface 6b and an operating surface 6a arranged opposite to each other along its thickness direction. The conductive surface 6b is used to contact the buttons of the electronic device, and the operating surface 6a is used to touch or press. When operating on the operating surface 6a, such as by pressing or sliding the operating surface 6a, the buttons on the electronic device can be operated so that the electronic device can produce corresponding actions or functions.

[0064] The connecting frame 4 surrounds the conductive member 6. A second latching part 41 is provided on the side of the connecting frame 4 away from the conductive member 6. The button structure 10 is embedded in the button hole 2 through the connecting frame 4 and the connecting frame 4 is placed on the mounting step 21. The first latching part 22 and the second latching part 41 are engaged, so that the button structure 10 is fixed relative to the protective frame 20 along the thickness direction of the conductive member 6. When the button structure 10 is embedded in the button hole 2, it is not easy for the button structure 10 to fall out of the button hole 2, whether it is facing inward or outward. This effectively improves the stability of the button structure 10 installed in the button hole 2 and avoids the situation of loss due to the button structure 10 falling out of the button hole 2.

[0065] The electronic device can be any of the following: mobile phone, tablet, smartwatch, etc., without any limitation.

[0066] The buttons on an electronic device can be pressable buttons, touch-sensitive buttons, or buttons that can be both pressable and touch-sensitive; there is no limitation on these. Similarly, the button structure 10 can be a pressable button structure 10, a touch-sensitive button structure 10, or a button structure 10 that can be both pressable and touch-sensitive; there is no limitation on these either.

[0067] In addition, the operating surface 6a can be lower than or flush with the outer surface of the frame wall 1, so that the operating surface 6a of the button structure 10 does not protrude from the outer surface of the frame wall 1, effectively reducing the probability of accidentally touching the button structure 10 and operating the button on the electronic device, thereby greatly improving the user experience. At the same time, it also allows the button structure 10 to be used on thinner frame walls 1.

[0068] The number of the first latching parts 22 is multiple, and the multiple first latching parts 22 are arranged at intervals along the circumference of the button hole 2; the number of the second latching parts 41 is multiple, and the multiple first latching parts 22 are arranged at intervals along the circumference of the connecting frame 4. When the button structure 10 is embedded in the button hole 2, the multiple second latching parts 41 are arranged in a one-to-one correspondence with the multiple first latching parts 22.

[0069] Therefore, the button structure 10 can be more securely embedded in the button hole 2 by the corresponding engagement of multiple second latching parts 41 with multiple first latching parts 22.

[0070] The number of first latching parts 22 can be two, three, or more, and is not limited here. Similarly, the number of second latching parts 41 can also be two, three, or more, and is not limited here.

[0071] Optionally, such as Figure 3 , Figure 6 and Figure 10As shown, the button hole 2 has a width direction (e.g.) Figure 3 Two first long sidewalls 2a are arranged opposite each other (in the direction shown in x2). A portion of a plurality of first latching parts 22 is disposed on one of the first long sidewalls 2a, and another portion of the plurality of first latching parts 22 is disposed on the other first long sidewall 2a; the connecting frame 4 has a cross-sectional area along its width direction (e.g., ...). Figure 3 Two second long sidewalls 4a are arranged opposite each other (in the direction shown in x3). A portion of a plurality of second latching parts 41 is disposed on one of the second long sidewalls 4a, and another portion of the plurality of second latching parts 41 is disposed on the other second long sidewall 4a. When the button structure 10 is embedded in the button hole 2, the two second long sidewalls 4a correspond one-to-one with the two first long sidewalls 2a, and the second latching parts 41 are engaged with the corresponding first latching parts 22.

[0072] Therefore, the multiple first latching parts 22 are disposed on the two first long sidewalls 2a of the key hole 2, allowing the multiple first latching parts 22 to be disposed within a larger space, thus enabling the first latching parts 22 to be relatively larger, and consequently enabling the first latching parts 22 to have higher structural strength, which is beneficial for the key structure 10 to be securely embedded in the key hole 2. Similarly, the multiple second latching parts 41 are disposed on the two second long sidewalls 4a of the connecting frame 4, allowing the multiple second latching parts 41 to be disposed within a larger space, thus enabling the second latching parts 41 to be relatively larger, and consequently enabling the second latching parts 41 to have higher structural strength, which is beneficial for the key structure 10 to be securely embedded in the key hole 2.

[0073] The button hole 2 can be any of the following: a long slot hole, a rectangular hole, etc., and is not limited here.

[0074] It should be explained that when the button structure 10 is embedded in the button hole 2, the width direction of the button hole 2 is parallel to the width direction of the connecting frame 4.

[0075] Furthermore, the number of first latching parts 22 disposed on the two first long sidewalls 2a may be equal or unequal, and is not limited here. Correspondingly, the number of second latching parts 41 disposed on the two second long sidewalls 4a may be equal or unequal, and is not limited here.

[0076] Optionally, when the number of first latching parts 22 disposed on the two first long sidewalls 2a is equal, the positions of the first latching parts 22 disposed on the two first long sidewalls 2a are also corresponding; when the number of second latching parts 41 disposed on the two second long sidewalls 4a is equal, the positions of the second latching parts 41 disposed on the two second long sidewalls 4a are also corresponding.

[0077] Therefore, when the button structure 10 is embedded in the button hole 2, the forces on the two second long sidewalls 4a of the connecting frame 4 are relatively symmetrical about the center line in the width direction, so that the button structure 10 can be more stably embedded in the button hole 2.

[0078] It should be understood that the above-mentioned number of first latching parts 22 disposed on the two first long sidewalls 2a is equal, which means that the number of first latching parts 22 disposed on one of the first long sidewalls 2a is the same as the number of first latching parts 22 disposed on the other first long sidewall 2a.

[0079] Specifically, when the number of first latching portions 22 disposed on the two first long sidewalls 2a is equal, the first latching portions 22 disposed on one of the first long sidewalls 2a are symmetrical about the center line of the width direction of the button hole 2. Here, the center line of the width direction of the button hole 2 refers to a straight line that bisects the width of the button hole 2 and is parallel to the length direction of the button hole 2.

[0080] When the number of second latching parts 41 disposed on the two second long sidewalls 4a is equal, the second latching parts 41 disposed on one of the second long sidewalls 4a are symmetrical about the center line in the width direction of the connecting frame 4. The center line in the width direction of the connecting frame 4 refers to a straight line that bisects the width of the connecting frame 4 and is parallel to the length direction of the connecting frame 4.

[0081] Furthermore, the number of first latching portions 22 provided on one of the first long sidewalls 2a can be one, two, or more, and is not limited here. Correspondingly, the number of second latching portions 41 provided on one of the second long sidewalls 4a can be one, two, or more, and is not limited here.

[0082] For example, the number of first latching parts 22 can be four, so that there are two first latching parts 22 on each first long sidewall 2a. The two first latching parts 22 can be respectively disposed close to the two short sidewalls of the key hole 2, that is, the two first latching parts 22 disposed on the same first long sidewall 2a can have a long distance between them along the length direction of the key hole 2. Correspondingly, the number of second latching parts 41 is four, so that there are two second latching parts 41 on each second long sidewall 4a. The two second latching parts 41 can be respectively disposed close to the two short sidewalls of the connecting frame 4, so that the two second latching parts 41 disposed on the same second long sidewall 4a can have a long distance between them along the length direction of the key hole 2. As a result, the force on the connecting frame 4 through the second latching parts 41 along the length direction of the key hole 2 can have a long distance, so that the connecting frame 4 is less likely to wobble in the key hole 2 along the length direction of the key hole 2, thereby allowing the key structure 10 to be more securely embedded in the key hole 2.

[0083] Optionally, such as Figure 7 As shown, the button hole 2 has two first short sidewalls 2b arranged opposite each other along its length direction and two first long sidewalls 2a arranged opposite each other along its width direction. A portion of a plurality of mounting steps 21 is provided on the two first long sidewalls 2a and another portion is provided on the two first short sidewalls 2b, and a first latching part 22 is provided between each two adjacent mounting steps 21.

[0084] Therefore, along the circumference of the button hole 2, multiple mounting steps 21 and multiple first latching parts 22 can be arranged in a cross pattern, so that when the button structure 10 is embedded in the button hole 2, the multiple mounting steps 21 can restrict the button structure 10 more evenly along the circumference of the button hole 2, and the multiple first latching parts 22 can also restrict the button structure 10 more evenly, thereby making the button structure 10 more stable when embedded in the button hole 2.

[0085] For example, the number of mounting steps 21 can be four. One mounting step 21 can be provided on each first long sidewall 2a and one mounting step 21 can be provided on each first short sidewall 2b. The number of first latching parts 22 can be four. One first latching part 22 is provided between each two adjacent mounting steps 21, and the four first latching parts 22 are symmetrically distributed on the two first long sidewalls 2a. Thus, while ensuring that the button structure 10 is stably embedded in the button hole 2, the number of mounting steps 21 and first latching parts 22 can be reduced, thus reducing the difficulty of setting.

[0086] In addition, there may be a gap between the adjacent mounting steps 21 and the first latching part 22, or there may be no gap; this is not limited here.

[0087] In some embodiments, such as Figure 5and Figure 9 As shown, the first latching part 22 has a limiting plane 221 extending in a direction perpendicular to the axial direction of the key hole 2, and the second latching part 41 has a second limiting plane 411 extending in a direction perpendicular to the thickness direction of the conductive member 6. When the key structure 10 is embedded in the key hole 2, the second limiting plane 411 abuts against the limiting plane 221.

[0088] Therefore, when the button structure 10 is embedded in the button hole 2, the second limiting plane 411 abuts against the limiting plane 221, which allows the connecting frame 4 and the mounting step 21 to have a larger contact area, so that the button structure 10 can be more stably embedded in the button hole 2.

[0089] Optionally, such as Figure 5 and Figure 9 As shown, the first latching part 22 also has a guide slope 222, which is disposed opposite to the limiting plane 221. The guide slope 222 is disposed opposite to the limiting plane 221 along the axial direction of the button hole 2. When the button structure 10 is embedded in the button hole 2, the guide slope 222 is used to guide the second latching part 41 to latch with the first latching part 22.

[0090] This allows the button structure 10 to be pressed and embedded in the button hole 2 with less effort, facilitating the installation of the button structure 10.

[0091] The guide slope 222 is inclined relative to the limiting plane. It can be a plane or an arc surface, and there is no limitation here.

[0092] The first latching part 22 mentioned above can be either a latching protrusion or a latching groove, and the second latching part 41 can be either a latching protrusion or a latching groove; there is no limitation on this.

[0093] Optionally, such as Figures 3-10 As shown, the first latching part 22 is a latching protrusion protruding from the wall of the button hole 2. The connecting frame 4 is an annular structure. The outer peripheral wall of the connecting frame 4 is provided with a second latching part 41 and a plurality of abutting protrusions 42. The second latching part 41 is located between two adjacent abutting protrusions 42. The second latching part 41 extends along the thickness direction of the connecting frame 4 (parallel to the thickness direction of the conductive member). The plurality of abutting protrusions 42 are spaced around the outer peripheral wall of the connecting frame 4. When the button structure 10 is embedded in the button hole 2, the plurality of abutting protrusions 42 abut against the plurality of mounting steps 21 one by one. Each abutting protrusion 42 abuts against the corresponding mounting step 21 along the thickness direction of the conductive member 6. The second latching part 41 has a groove or through hole on the side facing the first latching part 22. The latching protrusion is latched in the groove or through hole.

[0094] Therefore, when the button structure 10 is embedded in the button hole 2, it can be engaged in the slot by the snap-fit ​​protrusion, and the multiple abutting protrusions 42 and multiple mounting steps 21 abut against each other one by one, so that the button structure 10 is fixed relative to the protective frame 20 along the axial direction of the button hole 2. This makes the button structure 10 securely embedded in the button hole 2, and also makes the structure of the first snap-fit ​​part 22 and the second snap-fit ​​part 41 simple and easy to implement.

[0095] There are several ways to implement the slot on the outer peripheral wall of the connecting frame 4. In one possible implementation, the slot is formed by recessing the outer peripheral wall of the connecting frame 4 near the conductive surface 6b along the thickness direction of the conductive member 6 towards the operating surface 6a. In this case, a protrusion can also be provided on the outer peripheral wall of the connecting frame 4 near the conductive surface 6b. The protrusion extends away from the conductive member 6 in a direction perpendicular to the thickness direction of the conductive member 6, forming an abutment boss 42. The protrusion can be formed by bending, machining such as turning or milling, or welding, and is not limited here.

[0096] In addition, the guide slope 222 can be located on the side of the snap-fit ​​protrusion facing the receiving space 3, and the limiting plane 221 can be located on the side of the snap-fit ​​protrusion away from the receiving space 3. At this time, when the button structure 10 is embedded in the button hole 2, the button structure 10 can be pressed into the button hole 2 in the direction from inside the receiving space 3 to outside the receiving space 3 until the abutting boss 42 abuts against the mounting step 21, and the snap-fit ​​protrusion snaps into the slot, making the installation convenient and quick.

[0097] In another implementation where a slot is provided on the outer peripheral wall of the connecting frame 4, a first protrusion and a second protrusion are provided on the outer peripheral wall of the connecting frame 4. Both the first protrusion and the second protrusion extend towards the conductive surface 6b along the thickness direction of the conductive member 6. The first protrusion protrudes beyond the second protrusion along the thickness direction of the conductive member 6. The slot is provided on the first protrusion, and the second protrusion forms an abutting boss 42. At this time, the button structure 10 can be pressed into the button hole 2 in a direction from outside the receiving space 3 to inside the receiving space 3 until the abutting boss 42 abuts against the mounting step 21, and the locking protrusion is locked in the slot.

[0098] The material of the connecting frame 4 mentioned above can be hard plastic, stainless steel, copper and copper alloy, etc., and is not limited here.

[0099] The connecting frame 4 can be a sheet metal structural part, an injection-molded plastic part, or a machined part produced by turning, milling, or other processes; there are no restrictions on this.

[0100] Optionally, such as Figure 4 and Figure 8As shown, the mounting step 21 has a first abutting surface 211, which extends in a direction perpendicular to the axial direction of the key hole 2. The abutting boss 42 has a second abutting surface 421, which extends in a direction perpendicular to the thickness direction of the conductive member 6. When the key structure 10 is embedded in the key hole 2, the second abutting surface 421 abuts against the first abutting surface 211.

[0101] Therefore, when the button structure 10 is embedded in the button hole 2, the contact area between the connecting frame 4 and the mounting step 21 can be larger, so that the mounting step 21 can better restrict the button structure 10, and the button structure 10 can be more stably embedded in the button hole 2.

[0102] The first abutting surface 211 can be a plane, and the second abutting surface 421 can also be a plane, which allows the abutting boss 42 to have a larger contact area when it abuts against the mounting step 21, so that the mounting step 21 has a better limiting effect on the button structure 10 and the button structure 10 is more stable when embedded in the button hole 2.

[0103] In addition, along the axial direction of the key hole 2, the first abutting surface 211 is lower than the surface where the key hole 2 is located, that is, the surface of the mounting step 21 is lower than the opening of the key hole 2.

[0104] Therefore, when the button structure 10 is embedded in the button hole 2, it does not protrude from the surface of the frame wall 1, thus preventing the operating surface 6a from protruding from the frame wall 1 and effectively avoiding accidental operation of the electronic device due to accidental contact with the operating surface 6a. In addition, it can also reduce the impact of the mounting step 21 on the thickness of the button structure 10, so that the thickness of the button structure 10 can be adaptively set according to the thickness of the frame wall 1, making the button structure 10 suitable for protective shells 100 of different thicknesses.

[0105] In particular, along the axial direction of the button hole 2, the first abutting surface 211 can be set close to the middle area of ​​the button hole 2.

[0106] In some embodiments, such as Figures 4-10 As shown, the button structure 10 also includes an elastic element 7. The elastic element 7 has a through hole, the hole wall of which surrounds the conductive element 6. The operating surface 6a protrudes from the side of the elastic element 7 where the through hole is provided. The side of the elastic element 7 facing away from the conductive surface 6b is fixedly connected to the connecting frame 4.

[0107] Therefore, the elastic element 7 allows the conductive element 6 to move a certain distance along its thickness direction, so that when operating on the operating surface 6a, a certain pressure can be applied to the operating surface 6a, so that the conductive surface 6b can always be in contact with the button of the electronic device, thereby enabling the button of the electronic device to be touched more quickly and accurately, so that the electronic device can produce the corresponding action or function more quickly and accurately.

[0108] Furthermore, by protruding the side of the elastic element 7 with the through hole on the operating surface 6a, the obstruction of the elastic element 7 can be effectively avoided when operating the operating surface 6a, allowing the user's fingers to easily touch the operating surface 6a for operation, thus effectively improving the user experience.

[0109] The elastic element 7 is arranged around the conductive element 6 through the hole wall of the through hole. The side of the elastic element 7 facing away from the conductive surface 6b is fixedly connected to the connecting frame 4, which makes the connection between the elastic element 7, the conductive element 6 and the connecting frame 4 more secure.

[0110] Among them, the elastic element 7, the conductive element 6 and the outer frame can be integrally molded, making the connection between the elastic element 7 and the conductive element 6 and the outer frame more solid.

[0111] In addition, the material of the elastic element 7 can be elastic plastic, metal, silicone, etc., and there is no limitation. As long as the elastic element 7 can be elastically deformed when subjected to external force and can return to its original shape after the external force is removed, it is acceptable.

[0112] The aforementioned conductive member 6 may include a base and a plurality of conductive parts 61 disposed within the base. The conductive parts 61 extend along the thickness direction of the conductive member 6. The plurality of conductive parts 61 are arranged in an array within the base so that when a finger touches different positions of the operating surface 6a, the conductive parts 61 at different positions can generate signals to trigger different operating functions.

[0113] The base can be made of glue or plastic, and there is no limitation on its material. The conductive part 61 can be made of conductive metal, chemical metal composite material, etc., and there is no limitation on its material.

[0114] In some embodiments, such as Figures 4-10 As shown, the button structure 10 also includes a touch panel 5, which is disposed on the operating surface 6a of the conductive member 6.

[0115] Therefore, the touch panel 5 can protect the conductive component 6 from scratches, impacts, and other damage that could affect the operation of the electronic device's buttons. At the same time, it can also prevent the conductive component 6 from being oxidized due to direct contact with air or fingers. In addition, the touch panel 5 can also serve a certain decorative purpose, improving the aesthetics of the button structure 10.

[0116] When the electronic device needs to be operated by a button, the touch panel 5 can be touched, and then the conductive component 6 transmits the touch signal to the button of the electronic device. At this time, the controller of the electronic device will calculate the position of the finger and the function represented by that position based on the difference in current change.

[0117] The touch panel 5 can be glued to the conductive component 6, for example, by using double-sided tape or adhesive.

[0118] In addition, the touch panel 5 can be any of acrylic, glass, metal, etc., and there is no limitation here.

[0119] This application also discloses another button structure, which is installed on the protective casing 100 of the electronic device, such as... Figures 11-17 As shown, the electronic device protective case 100 includes a protective frame 20 and a button structure 10. The protective frame 20 includes multiple frame walls 1, which together form a receiving space 3 for accommodating the electronic device. Each frame wall 1 has a button hole 2 extending through it along its thickness. A mounting step 21 is provided on the wall of the button hole 2. The button structure 10 is embedded in the button hole 2 via a first connecting frame 43 and a second connecting frame 44 that are fastened together, with the mounting step 21 sandwiched between the first connecting frame 43 and the second connecting frame 44.

[0120] It should be noted that the electronic device in this embodiment may be the same as the electronic device described above, and the conductive member 6 may be the same as the conductive member 6 described above.

[0121] Therefore, the button structure 10 is embedded in the button hole 2 by the first connecting frame 43 and the second connecting frame 44 being fastened together, and the mounting step 21 is clamped between the first connecting frame 43 and the second connecting frame 44, so that the button structure 10 can be stably embedded in the button hole 2. That is, the button structure 10 is not easy to come out of the button hole 2, whether it is facing inward or outward, effectively improving the stability of the button structure 10 installed in the button hole 2.

[0122] In addition, the button structure 10 is embedded in the button hole 2 by the first connecting frame 43 and the second connecting frame 44 that are fastened together. During the process of embedding the button structure 10 into the button hole 2, the first connecting frame 43 and the second connecting frame 44 can be inserted into the button hole 2 from both sides until the first connecting frame 43 and the second connecting frame 44 abut against the mounting step 21 and the first connecting frame 43 and the second connecting frame 44 are fastened together. This will install the button structure 10 in place, effectively preventing the button structure 10 from coming out of the button hole 2 in the pressing direction, while also facilitating the installation of the button structure.

[0123] The button structure 10 includes a conductive member 6 and a connecting frame 4. The conductive member 6 has a thickness direction (e.g., along its thickness direction) Figure 12 The conductive surface 6b and the operating surface 6a are arranged opposite each other in the direction shown in x1. The conductive surface 6b is used to contact the button of the electronic device, and the operating surface 6a is used for touching or pressing. The connecting frame 4 surrounds the conductive component 6. The connecting frame 4 includes a first connecting frame 43 and a second connecting frame 44 that are fastened together. The button structure 10 is embedded in the button hole 2 through the fastened first connecting frame 43 and the second connecting frame 44, and the mounting step 21 is clamped between the first connecting frame 43 and the second connecting frame 44.

[0124] Therefore, by surrounding the conductive member 6 with the connecting frame 4, which includes a first connecting frame 43 and a second connecting frame 44 that are fastened together, the button structure 10 is embedded in the button hole 2 through the fastened first connecting frame 43 and the second connecting frame 44. The mounting step 21 is sandwiched between the first connecting frame 43 and the second connecting frame 44, which can fix the button structure 10 relative to the protective frame 20 along the thickness direction of the conductive member 6. When the button structure 10 is embedded in the button hole 2, it is not easy for the button structure 10 to fall out of the button hole 2, whether it is facing inward or outward. This effectively improves the stability of the button structure 10 installed in the button hole 2 and effectively avoids the situation of loss due to the button structure 10 falling out of the button hole 2.

[0125] It should be understood that when the button structure 10 is not embedded in the button hole 2, the first connecting frame 43 and the second connecting frame 44 can be in a separate state or in a snap-fit ​​connected state; when the button structure 10 needs to be embedded in the button hole 2, the first connecting frame 43 and the second connecting frame 44 are separate individual structures; after the first connecting frame 43 and the second connecting frame 44 are respectively placed into the button hole 2, the first connecting frame 43 and the second connecting frame 44 are in a snap-fit ​​connected state.

[0126] The operating surface 6a can be lower than or flush with the outer surface of the frame wall 1, so that the operating surface 6a of the button structure 10 does not protrude from the outer surface of the frame wall 1. This effectively reduces the probability of accidentally touching the button structure 10 and operating the button on the electronic device, thereby greatly improving the user experience. At the same time, it also allows the button structure 10 to be used with thinner frame walls 1.

[0127] Optionally, such as Figures 13-16As shown, the first connecting frame 43 includes a first main body 431 and a third latching part 432. The third latching part 432 is disposed on the outer peripheral wall of the first main body 431. The second connecting frame 44 includes a second main body 441 and a fourth latching part 442. The first main body 431 and the second main body 441 are both arranged around the conductor 6. The fourth latching part 442 is disposed on the outer peripheral wall of the second main body 441. When the button structure 10 is embedded in the button hole 2, the third latching part 432 and the fourth latching part 442 are engaged.

[0128] Therefore, the third latching part 432 is disposed on the outer peripheral wall of the first main body 431, and the fourth latching part 442 is disposed on the outer peripheral wall of the second main body 441, which facilitates the setting of the third latching part 432 and the fourth latching part 442. At the same time, it can also effectively prevent the third latching part 432 and the fourth latching part 442 from affecting the setting of the conductive member 6.

[0129] The third latching part 432 may include either a latching protrusion or a latching groove, and the fourth latching part 442 may include the other of a latching protrusion or a latching groove; neither is limited here. The following detailed description uses the example of the third latching part 432 including a latching protrusion and the fourth latching part 442 including a latching groove.

[0130] Optionally, such as Figure 15 and Figure 16 As shown, a first protrusion is provided on the outer peripheral wall of the first body 431, and the first protrusion forms a third latching part 432; a second protrusion is provided on the outer peripheral wall of the second body 441, and the end of the second protrusion away from the second body 441 extends toward the first body 431. A slot or hole is provided on the second protrusion, and the slot or hole forms a fourth latching part 442. When the button structure 10 is embedded in the button hole 2, the first protrusion is engaged with the slot or hole.

[0131] Therefore, the structures of the third latching part 432 and the fourth latching part 442 are relatively simple and easy to implement.

[0132] Both the first main body 431 and the second main body 441 are ring-shaped structures.

[0133] In addition, the second protrusion can be formed by bending the outer edge of the second body 441, or it can be formed by machining the outer peripheral wall of the second body 441 through processes such as turning and milling, or the second protrusion can be integrally injection molded with the second body 441, and there is no limitation here.

[0134] For example, when the second body 441 is an annular sheet structure, the second protrusion can be formed by bending the edge of the second body 441 toward the first body 431, and then a slot or hole is provided on the second protrusion.

[0135] The implementation of the first protrusion on the outer peripheral wall of the first body 431 can be the same as or different from the implementation of the second protrusion on the outer peripheral wall of the second body 441, and is not limited here.

[0136] The aforementioned first body 431 may have two long sidewalls arranged opposite each other along its width direction. The number of first protrusions may be multiple, with some of the multiple first protrusions arranged on one of the long sidewalls and others arranged on the other long sidewall. Correspondingly, the number of second protrusions may be multiple, and they are arranged one-to-one with the multiple first protrusions. Thus, the fastening connection between the first connecting frame 43 and the second connecting frame 44 can be relatively firm.

[0137] In addition, the number of first protrusions on the two long sidewalls is equal and they are symmetrically arranged about the center line of their width direction. Correspondingly, the number of second protrusions on the two opposite sidewalls of the second main body 441 is opposite and symmetrically arranged. This makes the force between the first connecting frame 43 and the second connecting frame 44 more balanced after they are fastened together, thus making the connection between the two more solid.

[0138] Optionally, such as Figures 12-14 As shown, the mounting step 21 includes a flange disposed on the wall of the button hole 2 along the circumference of the button hole 2. There are multiple flanges, which are spaced apart along the circumference of the button hole 2. There is a gap between two adjacent flanges, which is used to avoid the third latching part 432 and the fourth latching part 442.

[0139] This effectively prevents interference between the installation step 21 and the third and fourth latching parts 432 and 442.

[0140] When the fourth latching part 442 includes a latching groove or a latching hole, that is, a second protrusion is provided on the outer peripheral wall of the second body 441. The end of the second protrusion away from the second body 441 extends towards the first body 431. The second protrusion is provided with a latching groove or a latching hole. When the latching groove or the latching hole forms the fourth latching part 442, the length of the interval can be slightly greater than or equal to the length of the second protrusion along the circumferential direction of the key hole 2. This ensures that the interval can avoid the second protrusion while also ensuring that the length of the interval is not too large. This allows the flange to have a longer length along the circumferential direction of the key hole 2. When the key structure 10 is embedded in the key hole 2, the longer mounting step 21 can be sandwiched between the first connecting frame 43 and the second connecting frame 44, which helps to improve the stability of the key structure 10 embedded in the key hole 2.

[0141] Optionally, such as Figure 12 , Figures 15-16As shown, the first connecting frame 43 also includes a first clamping part 433, which is arranged around the outer peripheral wall of the first main body 431. The second connecting frame 44 also includes a second clamping part 443, which is arranged around the outer peripheral wall of the second main body 441. Along the thickness direction of the connecting frame 4 (which may be parallel to the thickness direction of the conductive member 6), the first clamping part 433 and the second clamping part 443 are arranged at intervals to form a clamping space. When the button structure 10 is embedded in the button hole 2, the mounting step 21 is clamped in the clamping space.

[0142] Therefore, the clamping space can be arranged around the first main body 431, so that multiple mounting steps 21 can be arranged on the wall of the key hole 2 along the circumference of the key hole 2, and all of them can be clamped in the clamping space, thereby making the key structure 10 more securely embedded in the key hole 2.

[0143] The first clamping part 433 is arranged around the outer peripheral wall of the first main body 431. It can be arranged around the entire outer peripheral wall of the first main body 431, or it can be arranged around a portion of the outer peripheral wall of the first main body 431. There is no limitation here.

[0144] Furthermore, when there are multiple first clamping parts 433, the multiple first clamping parts 433 can be arranged at intervals along the circumference of the first body 431 on the outer peripheral wall of the first body 431. The third latching part 432 is located between two adjacent first clamping parts 433.

[0145] Correspondingly, the second clamping portion 443 is disposed around the outer peripheral wall of the second body 441. This can be either a complete circumference of the outer peripheral wall of the second body 441 or a portion of the outer peripheral wall of the second body 441; neither is limited here. Furthermore, when there are multiple second clamping portions 443, these portions can be spaced apart along the circumference of the second body 441 on its outer peripheral wall.

[0146] For example, when there is one first clamping part 433 and multiple second clamping parts 443, one first clamping part 433 is arranged around the outer peripheral wall of the first body 431, and multiple second clamping parts 443 are arranged at intervals along the circumference of the second body 441 on the outer peripheral wall of the second body 441. When the first connecting frame 43 and the second connecting frame 44 are fastened together, a clamping space around the first body 431 can be formed between the first clamping part 433 and the multiple second clamping parts 443. The number of mounting steps 21 can be multiple, and multiple mounting steps 21 are arranged at intervals along the circumference of the key hole 2 on the hole wall of the key hole 2. Multiple mounting steps 21 can be clamped in the clamping space so that the key structure 10 can be more securely embedded in the key hole 2.

[0147] The first clamping part 433 described above can be implemented in various ways. For example, it can be formed by the edge portion of the first body 431, or it can be formed by a protruding structure provided on the outer peripheral wall of the first body 431, or it can be formed by bending the edge of the first body 431. No limitation is made here.

[0148] Optionally, such as Figure 15 and Figure 16 As shown, the first clamping portion 433 includes a first flange extending from the outer peripheral wall of the first body 431 in a direction away from the conductor 6, and / or the second clamping portion 443 includes a second flange extending from the outer peripheral wall of the second body 441 in a direction away from the conductor 6.

[0149] Therefore, the structures of both the first clamping part 433 and the second clamping part 443 are relatively simple and easy to implement.

[0150] For example, the first body 431 can be an annular columnar structure, and the first flange can be a boss provided around the outer peripheral wall of the first body 431, which is simple and easy to implement. In addition, when there are multiple first clamping parts 433, the number of first flanges can be multiple, and each first clamping part 433 can include one first flange.

[0151] The second body 441 can be a ring-shaped sheet structure. The second flange can be provided on the edge of the second body 441, and the second flange extends away from the conductor 6 in a direction parallel to the sheet structure to form a second clamping part 443. The second body 441 of the sheet structure can occupy a small space along the axial direction of the key hole 2, which is conducive to the thinning of the key structure 10, so that the key structure 10 can be used in the thinner protective frame 20.

[0152] In addition, the first flange and the first body 431 can be integrally formed, so that the connection between the first body 431 and the first flange can be relatively firm, and the snap-fit ​​connection between the first connecting frame 43 and the second connecting frame 44 can be relatively firm.

[0153] The second flange and the second body 441 can also be integrally formed, so that the connection between the second body 441 and the second flange can be more secure, and the snap-fit ​​connection between the first connecting frame 43 and the second connecting frame 44 can also be more secure.

[0154] Optionally, along the thickness direction of the conductive member 6, the first clamping part 433 is disposed near the side of the first body 431 away from the conductive surface 6b, and the third latching part 432 is disposed near the side of the first body 431 facing the conductive surface 6b.

[0155] Therefore, interference with the first clamping part 433 can be effectively avoided when the third latching part 432 and the fourth latching part 442 are engaged. Furthermore, the first clamping part 433 can also shield the third latching part 432 and the fourth latching part 442, so that the side of the button structure 10 facing the outside of the receiving space 3 can have better integrity, thus improving the aesthetics of the button structure 10.

[0156] In some embodiments, the button hole 2 is provided to form a first installation space and a second installation space that are interconnected by the mounting step 21. When the button is embedded in the button hole 2, the first connecting frame 43 is accommodated in the first installation space and the second connecting frame 44 is accommodated in the second installation space.

[0157] Therefore, the first connecting frame 43 and the second connecting frame 44 can be stacked along the axial direction of the key hole 2, so that the radial dimension of the connecting frame 4 along the key hole 2 can be smaller, so that the width of the protective frame 20 can be set smaller, thereby making the protective shell 100 suitable for thin and light electronic devices.

[0158] In addition, when the button structure 10 is embedded in the button hole 2, both the first connecting frame 43 and the second connecting frame 44 can be accommodated in the button hole 2, so that the button structure 10 is less likely to protrude from the button hole 2, effectively avoiding accidental operation due to the button structure 10 protruding from the button hole 2.

[0159] In some embodiments, such as Figures 12-15 As shown, the button structure 10 also includes an elastic element 7. The elastic element 7 includes a surrounding portion 71 and a connecting portion 72 that are connected to each other. The surrounding portion 71 is arranged around the conductor 6, and the connecting portion 72 is arranged around the surrounding portion 71. The connecting portion 72 extends away from the surrounding portion 71 in a direction perpendicular to the thickness direction of the conductor 6, and the connecting portion 72 is attached to the side of the second connecting frame 44 that is away from the first connecting frame 43.

[0160] Therefore, the elastic element 7 allows the conductive element 6 to move a certain distance along its thickness direction, so that when operating on the operating surface 6a, a certain pressure can be applied to the operating surface 6a, so that the conductive surface 6b can always be in contact with the button of the electronic device, thereby enabling the button of the electronic device to be touched more quickly and accurately, so that the electronic device can produce the corresponding action or function more quickly and accurately.

[0161] By having the enclosure 71 surrounding the conductor 6 and the connecting part 72 surrounding the enclosure 71, and attaching the connecting part 72 to the side of the second connecting frame 44 facing away from the first connecting frame 43, the connection between the elastic member 7 and the conductor 6 and the first connecting frame 43 can be made more secure.

[0162] Among them, the elastic element 7, the conductive element 6 and the first connecting frame 43 can be integrally formed by injection molding, so that the connection between the elastic element 7 and the conductive element 6 and the first connecting frame 43 is more solid.

[0163] In addition, the material of the elastic element 7 can be elastic plastic, metal, silicone, etc., and there is no limitation. As long as the elastic element 7 can be elastically deformed when subjected to external force and can return to its original shape after the external force is removed, it is acceptable.

[0164] The connecting part 72 can be a sheet-like structure, which helps to reduce the size of the button structure 10 along the axial direction of the button hole 2 (i.e., the thickness direction of the conductive member 6), so that the button structure 10 can be used in a thinner protective frame 20.

[0165] Optionally, along the thickness direction of the conductive member 6, the operating surface 6a protrudes from the side of the elastic member 7 near the operating surface 6a.

[0166] Therefore, when operating the operating surface 6a, the obstruction of the elastic element 7 can be effectively avoided, allowing the user's fingers to easily touch the operating surface 6a for operation, effectively improving the user experience.

[0167] In other embodiments, such as Figures 17-19 As shown, the mounting step 21 is provided with an insertion hole 212 extending axially along the button hole 2. The second connecting frame 44 also includes an insertion protrusion 444 and / or the first connecting frame 43 also includes an insertion protrusion 444. When the button is embedded in the button hole 2, the insertion protrusion 444 is inserted into the insertion hole 212.

[0168] Therefore, it can effectively prevent the button structure 10 from coming out of the button hole 2 due to the deformation of the hole wall of the button hole 2 caused by the radial force along the button hole 2 on the frame wall 1, so that the button structure 10 can be more stably embedded in the button hole 2.

[0169] It should be explained that the above-mentioned button structure 10 being fixed relative to the protective frame 20 along the radial direction of the button hole 2 means that when the frame wall 1 is subjected to a force along the radial direction of the button hole 2, causing the hole wall of the button hole 2 to deform, the button structure 10 does not move relative to the hole wall of the button hole 2 along the radial direction of the button hole 2, or only moves a small distance, so that the mounting step 21 can always be clamped between the first connecting frame 43 and the second connecting frame 44.

[0170] For example, when the second body 441 of the second connecting frame 44 is a sheet structure and the second connecting frame 44 includes a plugging protrusion, the plugging protrusion can be formed by bending the edge of the second body 441 toward the direction close to the first connecting frame 43. The process is simple and easy to implement.

[0171] In addition, there can be multiple sockets 212. Multiple sockets 212 can be disposed on two opposite first long sidewalls 2a of the button hole 2, and the sockets 212 disposed on the two first long sidewalls 2a are correspondingly set, which facilitates the setting of the sockets 212.

[0172] Correspondingly, there can be multiple protrusions, with each protrusion corresponding to a different socket 212.

[0173] The second connecting frame 44 may include a plugging protrusion, or the first connecting frame 43 may include a plugging protrusion 444, or both the second connecting frame 44 and the first connecting frame 43 may include a plugging protrusion.

[0174] In some embodiments, such as Figure 12 and Figure 13 As shown, the button structure 10 also includes a touch panel 5, which is disposed on the operating surface 6a of the conductive member 6.

[0175] Therefore, the touch panel 5 can protect the conductive component 6 from scratches, impacts, and other damage that could affect the operation of the electronic device's buttons. At the same time, it can also prevent the conductive component 6 from being oxidized due to direct contact with air or fingers. In addition, the touch panel 5 can also serve a certain decorative purpose, improving the aesthetics of the button structure 10.

[0176] When the electronic device needs to be operated by a button, the touch panel 5 can be touched, and then the conductive component 6 transmits the touch signal to the button of the electronic device. At this time, the controller of the electronic device will calculate the position of the finger and the function represented by that position based on the difference in current change.

[0177] The touch panel 5 can be glued to the conductive component 6, for example, by using double-sided tape or adhesive.

[0178] In addition, the touch panel 5 can be any of acrylic, glass, metal, etc., and there is no limitation here.

[0179] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
