Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Since electronic products generally do not have waterproof effect, the electronic products must be waterproof to avoid short circuit and other faults of internal electronic devices caused by water entering the electronic products. Some electronic products have waterproof function, and the electronic products are generally designed with waterproof structures at jacks, keys and the like of the electronic products so as to achieve waterproof effect.

Based on this, the inventors have conducted a great deal of research on the waterproof structure of the key. The inventor finds that the waterproof ring made of softer materials can be arranged on the periphery of the key in a surrounding mode, the key with the waterproof ring is arranged in the key hole of the shell, sealing is achieved through extrusion between the waterproof ring and the shell, and therefore the waterproof effect of the key of the electronic equipment is achieved. Under such waterproof construction, the inventor has found through repeated tests that when such a button is pressed, the hand feeling is astringent and the user experience is not good.

For this reason, the inventors continued to study the reason why such keys produce a harsh feel, wherein the inventors' studies included: the influence that different waterproof circle materials produced to the button is felt, and the influence that installation, the fixed knot of different waterproof circles felt to the button is felt, the influence that the extrusion degree of different waterproof circles felt to the button is felt and produces etc.. Through a large amount of repeated research on specified variables, the inventor finds that in the process of pressing the key, the waterproof ring moves along with the key, the shell needs to be sealed through extrusion between the waterproof ring and the shell, the friction force between the waterproof ring and the shell is necessarily large, the force is larger when a user presses the key than when the waterproof ring is not arranged, and the user feels labor when using the key and feels poor hand feeling. Therefore, the inventor further researches the problem of how to design a sealing structure which can achieve waterproof and key feel, and accordingly proposes the scheme provided by the embodiment of the application.

Referring to fig. 1, an electronic device 500 is provided in the present embodiment, where the electronic device 500 may be, but is not limited to, an electronic device such as a mobile phone and a tablet computer. The electronic device 500 of the present embodiment is described by taking a mobile phone as an example.

The electronic device 500 includes a housing assembly 100, a waterproof key 200, a display panel 400, and an electronic assembly (not shown in the drawings). The housing assembly 100 includes a middle frame 110 and a rear cover 120, the middle frame 110 is disposed between the display panel 400 and the rear cover 120, and the display panel 400, the rear cover 120 and the middle frame 110 together form an accommodating space in which the electronic component is accommodated. The middle frame 110 can provide a protection effect for the electronic component, and prevent the electronic component from being misplaced or damaged due to external impact, thereby prolonging the service life of the electronic device 500.

In the embodiment of the present application, the middle frame 110 is substantially in the shape of a rounded rectangular frame, and is used for forming a frame of the electronic device 500. It should be understood that the bezel of the electronic device 500 refers to a side portion of the electronic device 500 in the thickness direction, and the bezel forms an appearance of the electronic device 500 together with a rear side surface (e.g., the rear cover 120) and a front side surface (e.g., the display panel 400) of the electronic device 500. That is, the middle frame 110 has a certain height to provide support to the display panel 400 and the rear cover 120, and forms a receiving space having a certain space to receive electronic components. Alternatively, the middle frame 110 may be an integral structure with the front side surface, an integral structure with the rear cover 120, or a separate frame, and the specific structure form thereof is not limited herein.

The middle frame 110 may be a metal frame, for example, the middle frame 110 may be made of aluminum alloy, magnesium alloy, or the like. In some embodiments, the middle frame 110 may also be made of ceramic, glass, or the like. Alternatively, the middle frame 110 may be a structure in which metal and plastic are combined with each other, for example, the middle frame 110 may be formed by injection molding a plastic material onto a metal material.

Referring to fig. 2, the middle frame 110 includes a first side 111 and a second side 113 that are away from each other, the first side 111 is a side away from the accommodating space, and the second side 113 is a side facing the accommodating space. Further, the middle frame 110 is provided with a key mounting hole 115, and the key mounting hole 115 penetrates through the first side surface 111 and the second side surface 113. The key mounting holes 115 are used to mount the waterproof keys 200 so as to determine the mounting positions of the waterproof keys 200 on the middle frame 110 by the positions of the key mounting holes 115. Further, the middle frame 110 further includes a sidewall surface (not shown) surrounding the key mounting hole 115. The waterproof key 200 abuts against the side wall surface when being installed in the key installation hole 115 to form a sealing structure with the middle frame 110, thereby preventing liquid, vapor and the like from entering the electronic device 500 from the key installation hole 115, and preventing the electronic component from being damaged due to damp.

In the embodiment of the present application, the middle frame 110 directly serves as an outer frame of the electronic device 500, and when the waterproof button 200 is installed in the installation hole, the waterproof button 200 partially protrudes from the first side 111. Optionally, in an actual production process, the special appearance surface effect of the electronic device 500 may be achieved by adjusting the protrusion height of the waterproof button 200 relative to the appearance surface of the electronic device 500.

It is understood that the first side 111 of the middle frame 110 may be provided with a recess (not labeled), and the recess is formed by the first side 111 being recessed toward the second side 113. The recessed portion is used for accommodating a part of the structure of the waterproof key 200. During assembly, the waterproof button 200 is mounted at the position of the recessed portion, so that the protruding height of the waterproof button 200 relative to the first side surface 111 is lower and even flush with the first side surface 111, and the appearance surface of the electronic device 500 is smooth. It is understood that the recessed portion may be omitted, and a decorative shell (such as a battery rear cover with an outer frame, not shown in the figure) may be wrapped outside the middle frame 110, and the decorative shell is used as an appearance surface of the electronic device 500, at this time, the decorative shell may wrap the first side surface 111, so as to prevent the waterproof button 200 from forming a protrusion relative to the appearance surface of the electronic device 500, and further make the appearance surface of the electronic device 500 have smooth lines.

Furthermore, the middle frame 110 is further provided with a limiting protrusion 117, and the limiting protrusion 117 is formed protruding from the first side surface 111 and is adjacent to the key mounting hole 115. The limiting protrusion 117 is used for matching with the waterproof key 200, so that the waterproof key 200 can be fixed at the position of the key mounting hole 115. During assembly, the waterproof key 200 is mounted in the key mounting hole 115 and is engaged with the limiting protrusion 117 disposed on the first side 111, so that the waterproof key 200 is fixed relative to the middle frame 110 and is not easily separated due to external force. It is understood that, in order to reinforce the connection between the waterproof button 200 and the middle frame 110, the number of the limiting protrusions 117 may be plural, and the plurality of limiting protrusions 117 are disposed around the button mounting hole 115.

Referring to fig. 2, the waterproof key 200 includes a key main body 210 and a sealing member 300, the key main body 210 is disposed in the sealing member 300, the key main body 210 is movable relative to the sealing member 300, and a pressing signal is input to an electronic device in the middle frame 110 through the sealing member 300, so as to implement a key function. Specifically, one end of the sealing member 300 is fixed relative to the middle frame 110, and the other end of the sealing member 300 is movable under the external force of the key main body 210, for example, a part of the structure of the sealing member 300 deforms toward the electronic component in the middle frame 110, so as to input a pressing signal to the electronic component. The end of the key body 210 is sleeved with the sealing component 300, and the sealing component 300 is connected with the side wall surface forming the key mounting hole 115 in a sealing manner, so that liquid, water vapor and the like can be prevented from entering the electronic device 500 from the key mounting hole 115, and the electronic component is prevented from being damaged due to damp. In addition, during the movement of the key body 210, the body of the sealing assembly 300 is relatively fixed to the middle frame 110, only the end of the sealing assembly 300 is deformed, the influence of sliding friction force is avoided, and the pressing hand feeling can be improved.

Referring to fig. 3, the key body 210 includes a key cap 211 and a linking portion 213, and the key cap 211 is connected to the linking portion 213. In the present embodiment, key cap 211 has a substantially plate shape so as to be pressed by an external force. The interlocking portion 213 is substantially cylindrical to facilitate the sealing assembly 300 to be sleeved. Further, the linking portion 213 is connected to one side of the key cap 211, and a central axis of the linking portion 213 is substantially perpendicular to a plane where the key cap 211 is located, so that the linking portion 213 and the key cap 211 are substantially in a "T" shape. The key cap 211 and the linking portion 213 may be integrally formed (e.g., integrally formed by injection molding, die casting, etc.), detachably connected (e.g., screwed connection, etc.), and non-detachably connected (e.g., welded connection, etc.).

Alternatively, key cap 211 may be a metal key cap, a plastic key cap, or a key cap made of the same material as middle frame 110, etc. to provide different touch feeling and visual effect. Accordingly, the interlocking part 213 may be a metal column, a plastic column, or the like. It is understood that the material of the key cap 211 and the material of the interlocking part 213 may be the same or different. The key cap 211 and the interlocking part 213 may be made of hard materials (e.g., metal, hard plastic, etc.) to determine the transmission direction of the force. Specifically, the end structure of seal assembly 300 can be deformed toward the electronic component inside center frame 110 by the force applied to key cap 211 via interlocking portion 213. Furthermore, the surface of the key cap 211 away from the interlocking part 213 may be frosted or waxed, so as to improve the touch feeling of the user when performing key operation and enhance the aesthetic feeling of the appearance of the electronic device 500.

Referring to fig. 3, the sealing assembly 300 includes a fixing element 310 and an elastic element 330, the fixing element 310 is used for accommodating the key body 210 and is connected to the middle frame 110 for fixing, the elastic element 330 is fixedly connected to the fixing element 310, and the elastic element 330 can elastically deform relative to the fixing element 310.

The fixing member 310 includes a main body 311 and a catching portion 313 connected to the main body 311.

Referring to fig. 4, the main body 311 includes a first end 3111 and a second end 3113 facing away from each other. The body 311 has a through hole 3115, the through hole 3115 penetrates the first end 3111 and the second end 3113, and the through hole 3115 is used for accommodating the interlocking part 213. The radial dimension of the through hole 3115 is larger than the radial dimension of the interlocking portion 213, so that the interlocking portion 213 can move relative to the main body 311. Alternatively, the main body 311 is substantially hollow tube, wherein the main body 311 may be a hard material such as metal or plastic, for example, the main body 311 may be a metal tube, a plastic tube, or the like.

The positioning portion 313 is connected to the first end 3111, and is used for positioning the waterproof button 200 to the middle frame 110. The retaining portion 313 is substantially flat and projects radially from the outer peripheral wall of the main body 311 along the main body 311. Further, the central axis of the main body 311 is substantially perpendicular to the plane of the locking portion 313, so that the main body 311 and the locking portion 313 are substantially in a "T" shape. It is understood that the blocking portion 313 is substantially plate-shaped so as to be attached to the first side surface 111.

Alternatively, the main body 311 and the locking portion 313 are integrally formed, and they may be formed by die casting, injection molding, or the like, so as to firmly connect the main body 311 and the locking portion 313. The main body 311 and the latching portion 313 may be made of the same material, such as a hard material, such as metal, hard plastic, etc., so as to ensure that the main body 311 and the latching portion 313 are not deformed due to an external force, thereby ensuring a waterproof effect of the waterproof button 200.

Further, the catching portion 313 is provided with a catching hole 3131, and the catching hole 3131 is used to fix the sealing assembly 300 to the middle frame 110. In one embodiment, the locking hole 3131 is matched with the limiting protrusion 117, and the limiting protrusion 117 is locked or inserted into the locking hole 3131 to limit the position of the fixing portion 310, and thus the position of the sealing assembly 300. It is understood that the number and position of the catching holes 3131 correspond to those of the stopping protrusions 117. In the actual assembling process, the main body 311 is inserted into the key mounting hole 115, the position-limiting protrusion 117 is inserted into the position-limiting hole 3131, the position-limiting portion 313 abuts against the first side surface 111, and the fixing portion 310 is fixed relative to the assembling position of the middle frame 110. It can be understood that the position-locking portion 313 does not move with the movement of the key body 210, and the position-locking portion 313 and the middle frame 110 are kept relatively fixed.

Referring to fig. 4, the elastic element 330 surrounds the outer circumference of the main body 311, and an end of the elastic element 330 is fixedly connected to the second end 3113 and covers and closes the through hole 3115. The elastic member 330 can be elastically deformed by the pressing of the key body 210 and protrudes relative to the second end 3113. The elastic member 330 is fixedly connected to the second end 3113, so that during the pushing process of the key body 210, the elastic member 330 is partially deformed and protrudes relative to the second end 3113. It can be understood that when the elastic member 330 is elastically deformed, the sealing assembly 300 and the electronic device 500 are relatively fixed, and the key body 210 receives less friction and resistance in the process of pushing against the elastic member 330, so as to improve the pressing feel.

Further, as shown in fig. 3, the elastic member 330 includes a waterproof ring 331, a deformation portion 333, a sleeving portion 335, and a buffering portion 337. The covering portion 335 is disposed around the main body 311, the deformation portion 333 and the buffer portion 337 are respectively connected to two opposite ends of the covering portion 335, and the waterproof ring 331 is disposed around the covering portion 335. The division of the waterproof ring 331, the deformation portion 333, the sleeving portion 335, and the buffer portion 337 is only for describing the structure of the elastic member 330 in detail, and the specific structure of the elastic member 330 is not limited.

The covering portion 335 is substantially cylindrical, and covers the outer circumference of the main body 311 and is fixedly connected to the main body 311. The sleeve portion 335 is used to prevent the main body 311 from directly contacting the middle frame 110 to cause scratches or abrasion when the sealing assembly 300 is installed.

The buffer portion 337 is connected to an end of the cover portion 335 near the engaging portion 313. In the present embodiment, the buffer portion 337 is substantially sheet-shaped and is stacked on the side of the seating portion 313 facing the first side surface 111. The buffer portion 337 is used to form a buffer structure between the positioning portion 313 and the first side surface 111, so as to prevent the first side surface 111 from being damaged due to the impact of the positioning portion 313 on the first side surface 111 when receiving a large external force. When the key cap 211 abuts against the engaging portion 313 by an external force, the buffer portion 337 also abuts against the first side surface 111 by the external force. If the external force applied to the key cap 211 is too large, the buffering portion 337 is elastically deformed to play a role of buffering, thereby preventing the clamping portion 313 from directly contacting the first side surface 111. It can be understood that, in an initial state (i.e., a state where the key cap 211 is not pressed by an external force), the buffering member 337 can contact the first side surface 111, and when the key cap 211 is pressed by the external force, the buffering member 337 is elastically deformed to increase a friction force between the locking portion 313 and the first side surface 111, so that the fixing member 310 and the middle frame 110 are relatively fixed.

Further, the buffering portion 337 and the sleeving portion 335 may be made of an elastic material, and both may be integrally formed to improve the sealing performance of the elastic member 330, so as to provide waterproof protection for the main body 311 and the clamping portion 313. Alternatively, if the sleeve portion 335 is made of an elastic material (such as silicone), the buffering portion 337 may be made of another elastic material (such as thermoplastic polyurethane elastomer rubber), for example, the sleeve portion 335 and the buffering portion 337 may be integrally formed by a double injection molding process.

In the embodiment of the present application, the waterproof ring 331 is connected to the outer periphery of the sleeve portion 335 and protrudes relative to the outer peripheral wall of the sleeve portion 335. The waterproof ring 331 is substantially annular, and the waterproof ring 331 can be connected with the sleeve portion 335 by an adhesive connection. When the main body 311 is installed in the key installation hole 115, the waterproof ring 331 abuts against the side wall surface, or is in interference fit with the side wall surface, so that liquid, vapor and the like are prevented from entering the electronic device 500 from the key installation hole 115, and therefore the electronic component is prevented from being damaged due to damp. Further, the waterproof ring 331 is a waterproof ring made of an elastic material, such as a silica gel waterproof ring, so that the waterproof ring is deformed and in interference fit with the middle frame 110 by being pressed by force in the installation process, so as to increase the friction force between the sealing assembly 300 and the side wall surface, and prevent the sealing assembly 300 from being displaced relative to the side wall surface due to the action of external force, thereby ensuring a good sealing effect. It can be understood that the waterproof ring 331 and the sleeve portion 335 may be made of the same elastic material (e.g., silicone), and the waterproof ring 331 and the sleeve portion 335 may be integrally formed by injection molding.

In the embodiment shown in fig. 4, the waterproof ring 331 protrudes with respect to the outer circumferential wall of the cover portion 335, and the waterproof ring 331 is substantially triangular-convex. Specifically, the waterproof ring 331 includes a first surface 3311 and a second surface 3313, the first surface 3311 being a surface of the waterproof ring 331 facing the clamping portion 313, and the second surface 3313 being a surface of the waterproof ring 331 away from the clamping portion 313. In the embodiment of the present application, the first surface 3311 and the second surface 3313 are connected by a circular arc surface, and the waterproof ring 331 has a substantially triangular cross section along a plane where the axis of the through hole 3115 is located. The included angle between the plane of the first surface 3311 and the axis O of the through hole 3115 is smaller than the included angle between the plane of the second surface 3313 and the axis O of the through hole 3115. It should be noted that the included angles used for comparison are all acute angles. Thus, the second surface 3313 serves as a guide for allowing the elastic member 330 to be easily inserted into the key installation hole 115 in the assembly direction when the sealing member 300 is assembled to the key installation hole 115. It is to be understood that the convex shape of the waterproof ring 331 is not limited to the exemplified shape, and for example, the section of the waterproof ring 331 formed along the plane where the axis of the through-hole 3115 is located may be trapezoidal, circular, or the like.

Referring to fig. 5, it can be understood that the number of the waterproof rings 331 may be multiple, and a plurality of the waterproof rings 331 may be arranged in parallel on the outer circumference of the sleeve portion 335. When the sealing assembly 300 is installed in the key installation hole 115, the waterproof rings 331 can better improve the waterproof reliability of the electronic device 500, and prevent liquid, vapor and the like from entering the electronic device 500 from the key installation hole 115, thereby preventing the electronic assembly from being damaged due to moisture.

The deformation portion 333 is connected to an end of the sleeve portion 335 away from the buffering portion 337, and the deformation portion 333 covers and seals the through hole 3115, so that the through hole 3115 forms an accommodating groove (not shown) for accommodating the key body 210. Further, the deformation portion 333 is elastically deformed by an external force and protrudes from the second end 3113, so that the depth of the accommodating groove is correspondingly changed. It can be understood that the deformation part 333 receives external force from the key main body 210. That is, when the key body 210 moves in the through hole 3115, the deformation part 333 is deformed by pushing the deformation part 333. Further, the deformation portion 333 is made of an elastic material, such as a silicone material, a rubber material, etc., so as to have an ability of generating elastic deformation under an external force. It can be understood that the deformation portion 333 and the sleeve portion 335 may be made of the same elastic material (e.g., silicone), and the deformation portion 333 and the sleeve portion 335 may be integrally formed by injection molding.

Referring to fig. 4 again, in the embodiment of the present application, the deformation portion 333 is substantially sleeve-shaped, and a blind hole 3331 is disposed on a side of the deformation portion 333 facing the through hole 3115, and the blind hole 3331 is communicated with the through hole 3115 to form an accommodating groove. Alternatively, the deformation part 333 may be a silicone sleeve provided with a blind hole 3331. It should be noted that the deformation portion 333 can extend relative to the fixing member 310 under the action of an external force, so as to change the depth dimension of the blind hole 3331. Correspondingly, the depth dimension of the accommodating groove is changed under the action of external force.

It is understood that the deformation portion 333 is not limited to the structure having the blind hole 3331, and the deformation portion 333 may have other structures with elasticity, such as the deformation portion 333 may be a protrusion partially received in the through hole 3115, or the deformation portion 333 may have a flat plate shape. Alternatively, the deformation part 333 may be made of a non-elastic material, and may have a structure that can be elastically deformed so that the deformation part 333 can be elastically deformed, for example, when the deformation part 333 is made of a plastic having a small elasticity, it may have a spiral structure so that its end can be extended or contracted with respect to the fixing member 310. In the embodiment of the present application, the deformation of the deformation portion 333 is used to input a pressing signal to the electronic component, so the deformation portion 333 only needs to be a structure that can deform under the action of an external force.

In the embodiment of the present application, the connection structure between the fixing member 310 and the elastic member 330 is an integrally formed structure. Specifically, the main body 311, the locking portion 313, the waterproof ring 331, the deformation portion 333, the sleeving portion 335 and the buffering portion 337 are integrally formed, for example, by an insert molding process. For example, the main body 311 and the locking portion 313 may be made of a rigid material (e.g., a metal such as steel or iron, or a rigid plastic), and the waterproof ring 331, the deformation portion 333, the sleeve portion 335, and the buffering portion 337 may be made of an elastic material (e.g., silicone). At this time, the combined portion of the fixing member 310 and the elastic member 330 is relatively fixed, and only the deformation portion 333 is elastically deformed. The combination of the fixing member 310 and the elastic member 330 refers to the connection structure of the main body 311, the locking portion 313, the waterproof ring 331, the sleeve portion 335 and the buffer portion 337.

Further, the process of inputting the pressing signal to the electronic component may be implemented by providing a guide (not shown) for transmitting the pressing force to the electronic component. When the guiding part is subjected to external force, the guiding part inputs a pressing signal to the electronic assembly, and therefore the function of the electronic assembly is achieved. For example, referring to fig. 2, when the key cap 211 is not stressed, the linking portion 213 is partially accommodated in the accommodating groove, and at this time, the deformation portion 333 is not stressed by an external force, and the depth dimension of the accommodating groove maintains an initial state. Further, referring to fig. 6, when the key cap 211 is stressed, the linking portion 213 pushes the deformation portion 333, so that the deformation portion 333 protrudes from the second end 3113, and the depth of the accommodating groove is extended accordingly. At this time, the deformation unit 333 may apply an external force to the guide unit, and then input a pressing signal to the electronic component, thereby implementing a function related to the electronic component. Since the deformation portion 333 is made of an elastic material, when the key cap 211 is not stressed, the deformation portion 333 is restored to the initial state, and at this time, the depth dimension of the accommodating groove is also restored to the initial state.

It can be understood that the pressing force of the key cap 211 can be set by adjusting the depth of the initial state of the receiving groove or adjusting the partial length of the linking portion 213 received in the receiving groove, so as to obtain different hand feels and improve the user experience.

It is understood that the structure of the buffering portion 337 may be omitted. At this time, referring to fig. 7, when the sealing assembly 300 is inserted into the middle frame 110, the position-locking portion 313 directly abuts against the first side surface 111.

It will also be appreciated that the construction of the sleeve portion 335 may be omitted. Referring to fig. 8, the waterproof ring 331 can be disposed around the outer periphery of the main body 311 and tightly contact the sidewall surface, and the locking portion 313 is connected to the middle frame 110. At this time, the deformation portion 333 may be connected to the second end 3113 by an adhesive connection or an integral molding. It can be understood that, under the action of external force, the deformation portion 333 can protrude relative to the second end 3113, and the main body 311, the locking portion 313 and the waterproof ring 331 are all fixed relative to the middle frame 110, so that the sealing assembly 300 can still perform the sealing and waterproof functions. Further, at this time, the main body 311 may further be provided with a limiting groove (not shown in the figure), and the limiting groove is located on the outer peripheral wall of the main body 311 and is used for limiting the position of the waterproof ring 331, so as to prevent the waterproof ring 331 from sliding and dislocating in the installation process, which results in poor waterproofness.

In the sealing assembly 300, the waterproof button 200 and the electronic device 500 provided by this embodiment, the fixing member 310 can fix the mounting position of the sealing assembly 300, and the elastic member 330 abuts against the side wall surface, so as to achieve the waterproof of the electronic device 500. The key body 210 pushes against the elastic member 330 under the action of external force, so that the elastic member 330 protrudes from the second end 3113, thereby realizing the function of the key. Because the fixing member 310 is fixedly connected with the elastic member 330, when the elastic member 330 deforms, the whole sealing assembly 300 and the electronic device 500 are kept relatively fixed, and when the key main body 210 is pressed, the whole sealing assembly 300 cannot move relative to the side wall surface of the electronic device, so that the movement of the key main body 210 is not influenced by friction resistance, and the end of the elastic member 330 is pushed to enable the elastic member 330 to elastically deform, so that the key function can be realized, and the pressing hand feeling can be improved.
