Description

Technical Field

[0001] The present application belongs to the field of electronic technology, and specifically relates to a key and an electronic device. Background Art

[0002] Electronic devices are typically equipped with physical buttons, such as volume control buttons or power buttons. The electronic device includes a housing with a button mounting slot. The button is mounted within the slot, and the button's engaging portion engages with a retaining boss on the inner wall of the slot to secure the button to the housing, allowing it to be pressed or released normally and preventing it from falling off.

[0003] In the related art, a button includes a button body and a connecting portion connected to the button body, and a clamping portion is provided on the connecting portion. When the user applies a pressing force to the button body, the button body can drive the connecting portion to move synchronously in the button hole. Both the button body and the connecting portion are plastic parts. In order to facilitate the assembly of the clamping portion into the button hole of the shell, it is necessary to use a softer material to make the connecting portion so that the clamping portion can be deformed when entering the button hole and then enter the button hole. In order to ensure that the button can move when the button is pressed, it is necessary to use a harder material to make the button body, resulting in different materials for the button body and the connecting portion. However, with such an arrangement, during the use of the electronic device, the button body and the connecting portion are easily separated, causing the button body to fall off from the shell, thereby affecting the normal use of the electronic device. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a key and an electronic device that can solve the problem in the related art that the key body and the connecting portion of the key are easily separated, causing the key body to fall off the housing.

[0005] In a first aspect, an embodiment of the present application provides a key, the key comprising: The key body comprises a key body and a fixing portion protruding from the key body; a connecting portion, sleeved over at least a portion of the fixing portion, and connected to the fixing portion and the key body respectively, the connecting portion being provided with a clamping portion, the clamping portion being used to connect to a housing of an electronic device; In which, the fixing part is provided with a first limiting hole and a connecting space, the connecting part is provided with a first limiting part and a second limiting part, the opening direction of the first limiting hole intersects with the thickness direction of the button body, and the connecting space is arranged along the thickness direction of the button body. The first limiting hole is connected to the connecting space, and the first limiting part is embedded in the first limiting hole and connected to the hole wall of the first limiting hole. The second limiting part is embedded in the connecting space and connected to the side wall of the connecting space, and the second limiting part is connected to the first limiting part.

[0006] In the second aspect, an embodiment of the present application also provides an electronic device, which includes a shell and the above-mentioned button, the shell is provided with a button mounting groove, the inner wall of the button mounting groove is provided with a limiting boss, part of the button is located in the button mounting groove, and in the opening direction of the button mounting groove, the clamping part of the connecting part of the button is limitedly matched with the limiting boss.

[0007] In the embodiment of the present application, the connection area between the connecting portion and the fixing portion can be increased by the mutual cooperation between the first limiting portion and the first limiting hole, and since the opening direction of the first limiting hole intersects with the thickness direction of the key body, when the key is subjected to external force, the mutual cooperation between the first limiting portion and the first limiting hole can effectively resist the tension and shear force in the thickness direction of the key body, thereby preventing relative displacement or detachment between the connecting portion and the fixing portion.

[0008] The connecting space is arranged along the thickness direction of the key body and is connected to the first limiting hole. The second limiting part is embedded in the connecting space and connected to the side wall of the connecting space.

DETAILED DESCRIPTION

[0011] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0012] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0013] The following describes in detail the key and electronic device provided in the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0014] refer to Figure 1-Figure 39A key 300 provided in an embodiment of the present application can be applied to an electronic device. The key 300 may include a key body 100 and a connecting portion 200. The key body 100 may include a key body 110 and a fixing portion 120 protruding from the key body 110. The connecting portion 200 may be sleeved outside at least a portion of the fixing portion 120, and the connecting portion 200 may be connected to the fixing portion 120 and the key body 110 respectively. Here, the connecting portion 200 is simultaneously connected to the fixing portion 120 and the key body 110, forming a multi-point connection structure, thereby increasing the connection area between the connecting portion 200 and the key body 100. The connecting portion 200 may be provided with a clamping portion 210, which may be used to connect to the housing of the electronic device so that the key 300 is installed on the housing.

[0015] Optionally, the key body 100 may include two fixing portions 120, and both fixing portions 120 may be protruded from the key body 110. Specifically, the two fixing portions 120 may protrude along the thickness direction of the key body 110, and the two fixing portions 120 may be spaced apart along the length direction of the key body 110. For example, the two fixing portions 120 may be respectively disposed close to both ends of the key body 110 in the length direction. The key 300 may include two connecting portions 200, and the two connecting portions 200 may be respectively sleeved on at least part of the corresponding fixing portions 120, and the clamping portions 210 of the two connecting portions 200 may be connected to the shell. This arrangement can, on the one hand, improve the connection stability between the key 300 and the shell, and on the other hand, improve the balance of the key 300. As Figure 1 As shown, each connecting portion 200 can be provided with three clamping portions 210, one of which can be provided on the side where the two connecting portions 200 are away from each other, and the other two clamping portions 210 can be respectively provided on both sides of the connecting portion 200 in the width direction of the key body 100. This arrangement can improve the connection stability between the key 300 and the shell.

[0016] Among them, such as Figure 2 、 Figure 9 、 Figure 13 and Figure 18As shown, the fixing portion 120 can be provided with a first limiting hole 121 and a connecting space 122, and the connecting portion 200 can be provided with a first limiting portion 220 and a second limiting portion 230. The opening direction of the first limiting hole 121 can intersect with the thickness direction of the button body 100, and the connecting space 122 can be set along the thickness direction of the button body 100. The first limiting hole 121 can be connected to the connecting space 122, and the first limiting portion 220 can be embedded in the first limiting hole 121 and connected to the hole wall of the first limiting hole 121. The second limiting portion 230 can be embedded in the connecting space 122 and connected to the side wall of the connecting space 122, and the second limiting portion 230 can be connected to the first limiting portion 220.

[0017] In the embodiment of the present application, the connection area between the connecting portion 200 and the key body 100 can be increased through the mutual cooperation between the first limiting portion 220 and the first limiting hole 121, and since the opening direction of the first limiting hole 121 intersects with the thickness direction of the key body 100, when the key 300 is subjected to external force, the mutual cooperation between the first limiting portion 220 and the first limiting hole 121 can effectively resist the tension and shear force in the thickness direction of the key body 100, and even if the binding force between the connecting portion 200 and the key body 100 is completely lost, relative displacement or separation between the connecting portion 200 and the key body 100 can be prevented.

[0018] The connecting space 122 is set along the thickness direction of the button body 100 and is connected to the first limiting hole 121. The second limiting part 230 is embedded in the connecting space 122 and is connected to the side wall, and is connected to the first limiting part 220 at the same time. On the one hand, the connection area between the connecting part 200 and the fixing part 120 can be increased to improve the connection stability between the connecting part 200 and the button body 100. On the other hand, the connecting space 122 is set along the thickness direction of the button body 100 and is connected to the first limiting hole 121. The second limiting part 230 is embedded in the connecting space 122 and is connected to the first limiting part 220. The first limiting part 220 and the second limiting part 230 can form a complex three-dimensional connection structure in an "L" shape or a "T" shape. The external force perpendicular to the thickness direction of the button body 100 can be transmitted to the second limiting part 230 through the first limiting part 220, and then transmitted to the second limiting part 230 through the connecting part 220. The side walls of the space 122 are dispersed to the button body 100, and the external force in the thickness direction can be transmitted to the first limiting part 220 through the second limiting part 230, and then dispersed to the button body 100 through the hole wall of the first limiting hole 121. This multi-directional force dispersion structure can greatly improve the anti-displacement ability of the connecting part 200 in the three-dimensional space, thereby improving the connection strength between the connecting part 200 and the button body 100, thereby improving the stability and reliability of the overall structure of the button 300, and reducing the probability of failure of the button 300 due to structural looseness, thereby extending the service life of the button 300, improving the durability of the product, and providing users with a better use experience. In addition, the button 300 provided in the embodiment of the present application is not only conducive to reducing the cost of the entire electronic device, but also conducive to reducing the size of the button 300, thereby conducive to achieving the ultimate size of the electronic device. In the optional embodiment of the present application, such as Figure 6 As shown, both ends of the first limiting portion 220 can be connected to the connecting portion 200. This arrangement allows the connecting portion 200 to be locked with the key body 100, forming a non-detachable structure of the connecting portion 200 and the key body 100. This further prevents the connecting portion 200 from separating from the key body 100, ensuring a tight connection between the connecting portion 200 and the key body 100, thereby improving the reliability and durability of the key 300. In one embodiment, both ends of the first limiting portion 220 can be directly connected to the connecting portion 200. In another embodiment, one end of the first limiting portion 220 can be directly connected to the connecting portion 200, while the other end can be connected to the connecting portion 200 via the second limiting portion 230.

[0019] In other embodiments, only one end of the first limiting portion 220 may be connected to the connecting portion 200 , and the other end of the first limiting portion 220 may not be connected to the connecting portion 200 .

[0020] In an optional embodiment of the present application, Figure 2 and Figure 3As shown, the first limiting hole 121 passes through the fixing portion 120, the first limiting portion 220 is disposed in the first limiting hole 121, and both ends of the first limiting portion 220 are respectively connected to the connecting portion 200. In this embodiment, the first limiting portion 220 passes through the first limiting hole 121 of the fixing portion 120 and is respectively connected to the connecting portion 200 at both ends, so that the connecting portion 200 and the fixing portion 120 form a structural lock, so that the connecting portion 200 and the fixing portion 120 are tightly combined into a whole, effectively increasing the contact area and connection points between the connecting portion 200 and the fixing portion 120, and significantly improving the connection strength between the two. Moreover, because the first limiting portion 220 is located in the first limiting hole 121, even if the binding force between the connecting portion 200 and the fixing portion 120 is completely lost, the connecting portion 200 and the fixing portion 120 will not separate. The first limiting hole 121 extending through the fixing portion 120 cooperates with the first limiting portion 220 to strictly limit the relative position between the fixing portion 120 and the connecting portion 200. This effectively constrains the key 300 in all directions, preventing unnecessary relative displacement between the connecting portion 200 and the fixing portion 120. Furthermore, the design of the first limiting hole 121 extending through the fixing portion 120 is relatively simple and straightforward; a single through-hole and a cooperating limiting portion are all that are required to achieve a locked connection between the connecting portion 200 and the fixing portion 120.

[0021] In other embodiments, the first limiting hole 121 may not pass through the fixing portion 120 .

[0022] In an optional embodiment, as Figure 13 and Figure 14 As shown, the first limiting hole 121 penetrates the fixing portion 120 along the width direction of the key body 100, and the size of the first limiting hole 121 is larger than the size of the connecting space 122 in the length direction of the key body 100. In this arrangement, the first limiting hole 121 penetrates the fixing portion 120 along the width direction, providing a through-type installation path in the width direction for the first limiting portion 220. Moreover, the size of the first limiting hole 121 is larger than the size of the connecting space 122, so that the first limiting portion 220 and the second limiting portion 230 can form an "L"-shaped locking structure in the length direction of the key body 100, or a "T"-shaped locking structure in the width direction of the key body 100. On the one hand, this can increase the connection area between the connecting portion 200 and the fixing portion 120, and on the other hand, it can make the locking structure formed by the first limiting portion 220 and the second limiting portion 230 more complex, thereby further improving the connection strength between the connecting portion 200 and the fixing portion 120.

[0023] In other embodiments, in the length direction of the button body 100 , the size of the first limiting hole 121 may also be no larger than the size of the connecting space 122 .

[0024] In another optional embodiment, as Figure 9 and Figure 10 As shown, the first limiting hole 121 is provided along the length of the key body 100, and the first limiting hole 121 is a blind hole. This arrangement ensures the stability of the connection between the connecting portion 200 and the fixing portion 120, and can better preserve the structural integrity of the fixing portion 120 in the width direction. It is also less likely to form a weak area penetrating the width direction of the key body 100, which can reduce the stress concentration caused by the penetrating hole in the fixing portion 120, thereby improving the structural strength of the fixing portion 120.

[0025] Of course, the first limiting hole 121 may also pass through the fixing portion 120 along the length direction of the key body 100. Alternatively, the first limiting hole 121 may also be provided along the width direction of the key body 100, and the first limiting hole 121 may be a blind hole.

[0026] In the above embodiment, if Figure 9 and Figure 13 As shown, the connecting space 122 can be a second limiting hole 1221. Since the second limiting hole 1221 is a closed space opened on the fixing part 120, the second limiting hole 1221 will not destroy the overall continuity of the fixing part 120. The material of the fixing part 120 still maintains a complete connection around the second limiting hole 1221, thereby enabling the fixing part 120 to better withstand external forces and maintain the stability of the structure.

[0027] In an optional embodiment, if Figure 18 and Figure 21 As shown, the fixing portion 120 may include a first fixing portion 1201 and a second fixing portion 1202 that are relatively arranged, a connecting space 122 may be formed between the first fixing portion 1201 and the second fixing portion 1202, and both the first fixing portion 1201 and the second fixing portion 1202 may be provided with a first limiting hole 121. Optionally, the first limiting hole 121 of the first fixing portion 1201 and the first limiting hole 121 of the second fixing portion 1202 may be coaxially arranged or staggered. In this embodiment, a connecting space 122 is formed between the first fixing portion 1201 and the second fixing portion 1202, so that the connecting space 122 has a groove 1222 structure, which is conducive to increasing the volume of the second limiting portion 230, and can form two first limiting portions 220 on the connecting portion 200, so that the two first limiting portions 220 pass through the first limiting holes 121 on the first fixing portion 1201 and the second fixing portion 1202 respectively and are connected to the second limiting portion 230, thereby increasing the connection area between the first limiting portion 220 and the second limiting portion 230, thereby further improving the connection strength between the connecting portion 200 and the button body 100.

[0028] In other embodiments, the fixing portion 120 may include only the first fixing portion 1201 or the second fixing portion 1202. Alternatively, when the fixing portion 120 includes the first fixing portion 1201 and the second fixing portion 1202, the first limiting hole 121 is provided on one of the first fixing portion 1201 and the second fixing portion 1202.

[0029] In an optional embodiment, if Figure 1 and Figure 21 As shown, the key body 100 may further include a fixing boss 130. The fixing boss 130 may be disposed on the key body 110. The fixing boss 130 and the fixing portion 120 may be distributed along the length of the key body 100. A trigger portion 140 may be disposed on the fixing boss 130. The trigger portion 140 may be used to trigger a switch on a circuit board of an electronic device. In this embodiment, the fixing boss 130 supports and secures the trigger portion 140, facilitating triggering of the switch by the trigger portion 140. The fixing boss 130 also reinforces the key body 110, thereby increasing the structural strength of the key body 110.

[0030] like Figure 21 As shown, a gap 150 may be provided between the fixing portion 120 and the fixing boss 130, and the connecting portion 200 may further be provided with a first connecting portion 250. The first connecting portion 250 may be embedded in the gap 150, and the first connecting portion 250 is respectively connected to the second limiting portion 230, the fixing portion 120, the fixing boss 130, and the key body 110. This arrangement can further increase the connection area between the connecting portion 200 and the key body 100, and the first connecting portion 250 simultaneously connects the second limiting portion 230, the fixing portion 120, the fixing boss 130, and the key body 110, which can further form a three-dimensional locking structure between the connecting portion 200 and the key body 100, further improving the anti-pullout capability of the connecting portion 200, and further reducing the risk of separation of the connecting portion 200 and the key body 100.

[0031] In other embodiments, the gap 150 may not be provided between the fixing portion 120 and the fixing boss 130 , and the connecting portion 200 may not be provided with the first connecting portion 250 . For example, the fixing portion 120 and the fixing boss 130 may be an integrated structure.

[0032] Alternatively, as Figure 18As shown, the fixing portion 120 may further include a third fixing portion 1203. The third fixing portion 1203 may be located on a side of the first fixing portion 1201 and the second fixing portion 1202 away from the fixing boss 130, and both the first fixing portion 1201 and the second fixing portion 1202 may be connected to the third fixing portion 1203. This arrangement may improve the structural strength of the fixing portion 120, and the second limiting portion 230 may be connected to the third fixing portion 1203, thereby improving the connection strength between the key body and the connecting portion.

[0033] Further optionally, the third fixing portion 1203 may be provided with a first limiting hole 121. Correspondingly, a first limiting portion 220 is provided at a position of the connecting portion 200 corresponding to the third fixing portion 1203. The first limiting portion 220 is embedded in the first limiting hole 121 of the third fixing portion 1203 and connected to the hole wall of the first limiting hole 121. This arrangement can further increase the connection area between the connecting portion 200 and the fixing portion 120, thereby further improving the connection strength between the connecting portion 200 and the fixing portion 120.

[0034] In an optional embodiment, if Figure 18 As shown, the fixing portion 120 is provided with at least two first limiting holes 121. Correspondingly, the connecting portion 200 can be provided with at least two first limiting portions 220, each of which is embedded in its corresponding first limiting hole 121. In this way, the connecting portion 200 and the fixing portion 120 are connected through the interlocking structure of at least two groups of first limiting holes 121 and the first limiting portions 220, which can further improve the connection strength between the connecting portion 200 and the fixing portion 120.

[0035] Of course, only one first limiting hole 121 may be provided on the fixing portion 120 .

[0036] Alternatively, as Figure 18 As shown, the first limiting holes 121 are distributed in parallel along the length direction of the button body 100. This arrangement facilitates mold opening and helps simplify the structure of the mold.

[0037] Alternatively, the opening directions of at least two first limiting holes 121 intersect with each other. This arrangement allows the connecting portion 200 and the fixing portion 120 to be connected in different directions, thereby further improving the connection strength between the connecting portion 200 and the fixing portion 120.

[0038] In an optional embodiment, if Figure 8 and Figure 13 As shown, the fixing portion 120 may further be provided with a limiting groove 123, as shown in FIG. Figure 6 、 Figure 12 and Figure 16As shown, the connecting portion 200 may also be provided with a second connecting portion 240. The second connecting portion 240 may be embedded in the limiting groove 123 and engage with the groove wall of the limiting groove 123 to limit the key body 100 in the width, length, and thickness directions. In this embodiment, the groove wall of the limiting groove 123 can act as a multi-directional limiter for the second connecting portion 240, thereby restricting the movement of the connecting portion 200 in multiple directions, such as the width, length, and thickness directions of the key body 100. At the same time, this multi-directional limiter and dual-fixation structure can effectively prevent the connecting portion 200 from separating from the key body 100 during use.

[0039] In other embodiments, the button body 100 may not be provided with the limiting groove 123 , and the connecting portion 200 may not be provided with the second connecting portion 240 .
