Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.

At present, a side key assembly method commonly used in the field of electronic equipment is to install a side key into a middle frame, and after a buckling position of the side key enters an assembly groove in the middle frame, the side key is inserted into the assembly groove by using a fixing bracket to clamp the buckling position of the side key, so as to achieve the purpose of preventing the side key from being disengaged. However, the fixing bracket has a complex structure, and a T-shaped groove is often required to be formed in the middle frame to limit the fixing bracket, thereby increasing the manufacturing cost. Meanwhile, the fixed support is complex to disassemble, and a tool is required to pry the fixed support out during disassembly, so that the middle frame is easy to damage. On the other hand, the side key usually needs two fixing brackets, so that the manufacturing cost and the assembly cost are increased, the assembly is complicated, and the problem of protruding top battery cover and the like can be caused due to the improper assembly.

In order to simplify the assembly process of the key, in some methods, two fixing brackets are combined into one to form a larger bracket. Therefore, although the number of the fixing brackets is reduced and the assembly process is simplified, the size of the bracket is greatly increased, so that the opening hole in the middle frame is too large, and the waterproof width of the middle frame is sacrificed. Meanwhile, the size of the bracket is large, and the structure is complex, so that the processing difficulty is increased.

In order to solve the above problems, the inventors have studied and proposed a key assembly, a key, and an electronic device in the embodiments of the present application.

In order to make the technical solutions better understood by those skilled in the art, 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.

Referring to fig. 1, a key assembly 100 according to an embodiment of the present disclosure includes a frame 110, a key body 120, and an elastic clip 130. The frame body 110 has a mounting groove 111, the frame body 110 further includes a limiting portion 112 (see fig. 2), the key body 120 is disposed in the mounting groove 111, the elastic clip 130 is disposed on the key body 120, and the elastic clip 130 extends into the frame body 110 through the mounting groove 111 and is connected to the limiting portion 112 in a snap-fit manner.

The key assembly 100 is connected with the limiting part 112 through the elastic buckle 130 in a buckling manner, so that the key main body 120 can be fixed in the mounting groove 111 without a key fixing support, the structural design is simplified, the material and manufacturing cost are saved, and the problems of a top battery cover and the like caused by the fact that the fixing support cannot be assembled in place are avoided; in addition, in the assembling process, the elastic buckle 130 is directly installed in the frame body 110 through the installation groove 111, and the elastic buckle 130 can be buckled and connected with the limiting part 112 after rebounding and resetting, so that the whole assembling process is convenient and fast, and the assembling cost is saved.

The key assembly 100 provided in the embodiment of the present application may be applied to an electronic device, and the electronic device may be, but is not limited to, an electronic device such as a mobile phone, a tablet computer, and a smart watch. In this embodiment, a mobile phone is taken as an example for description, the frame body 110 may be a middle frame or a side frame of the mobile phone, the frame body 110 includes a first surface 113 and a second surface 114 that are adjacent to each other, the first surface 113 may be an appearance surface of the middle frame of the mobile phone, and the second surface 114 may be a side surface of the middle frame of the mobile phone facing the battery cover or the rear cover. The mounting groove 111 may be disposed on the first surface 113, and an extending direction of the mounting groove 111 is consistent with a length direction of the frame 110, and the key body 120 may serve as a power key, a volume key, or other keys of the mobile phone.

In the embodiment of the present application, the key body 120 includes an outer surface 121 and an inner surface 122 facing away from each other, the outer surface 121 is disposed on the same side as the first surface 113, and the elastic buckle 130 is disposed on the inner surface 122. The key body 120 is substantially elongated, and the longitudinal direction of the key body 120 coincides with the longitudinal direction of the housing 110. The key main body 120 is fitted into the mounting groove 111, and only a micro gap for the key main body 120 to press is left between the key main body 120 and the mounting groove 111.

Referring to fig. 2, in the embodiment of the present disclosure, the elastic buckle 130 includes a buckle main body 131 and a clamping leg 132, one end of the buckle main body 131 is disposed on the key main body 120, the other end of the buckle main body 131 is disposed with the clamping leg 132, and the clamping leg 132 is in buckling connection with the limiting portion 112. The elastic buckle 130 can form an inverted buckle in the frame 110 through the clamping leg 132 to abut against the limiting part 112, so that the connection stability and firmness are further improved, the fixing mode is simple, and the installation is convenient and quick.

In some embodiments, the latch body 131 is substantially a cylindrical structure, the latch 132 is substantially a sheet-like structure formed by bending one end of the latch body 131, and an included angle between the latch 132 and the latch body 131 may be an acute angle.

Because the clamping leg 132 is bent towards the buckle main body 131 to be close, the occupied space between the clamping leg 132 and the buckle main body 131 can be reduced, and the structure is more compact. As an example, the included angle between the clamping leg 132 and the buckle main body 131 may be 50 ° -70 °, and a stable triangular structure is formed between the clamping leg 132 and the buckle main body 131, which can further increase the stability and firmness of the buckle connection.

In other possible embodiments, the elastic clip 130 may have other shapes, such as a clip main body 131 and a clip leg 132 perpendicular to each other, and the clip connection with the position-limiting portion 112 may also be realized.

Referring to fig. 2 and 3, in the embodiment of the present invention, the frame body 110 is provided with a disassembly hole 115 (see fig. 1 in detail), the disassembly hole 115 and the installation groove 111 are communicated with each other in the frame body 110, and the locking pin 132 is exposed in the disassembly hole 115. Therefore, when the key body 120 needs to be disassembled, a tool can penetrate through the disassembling hole 115 to extend into the frame body 110 and extrude the clamping leg 132 to move towards the buckle body 131, the clamping leg 132 can be separated from the limiting part 112, the key body 120 is taken down, the whole disassembling process is convenient and rapid, and mechanical damage to the frame body 110 cannot be caused. Meanwhile, the disassembly hole 115 has a simple structure, so long as the clamping pin 132 can be exposed and the insertion of foreign objects is facilitated, the processing of redundant assembly characteristics is not required, the processing precision is not required to be accurately controlled, the processing is convenient, and the processing and manufacturing cost can be effectively reduced. In addition, the disassembly hole 115 is only used for applying external force to the clamping pin 132, and the cross-sectional area of the disassembly hole 115 can be small, so that the structural strength of the frame body 110 is prevented from being damaged, and the water leakage risk is reduced.

In the embodiment of the present application, the frame body 110 includes an inner surface 116, the inner surface 116 and the limiting portion 112 are disposed opposite to each other, a limiting groove 117 is disposed between the inner surface 116 and the limiting portion 112, and the locking pin 132 is received in the limiting groove 117. The limiting groove 117 is used for accommodating the clamping pin 132 and providing a moving space for the elastic buckle 130, and when the key body 120 is pressed, the elastic buckle 130 can move back and forth in the limiting groove 117.

In some embodiments, the inner surface 116 includes a first inner surface 1161 and a second inner surface 1162 having a stepped shape, a distance between the first inner surface 1161 and the first surface 113 is smaller than a distance between the second inner surface 1162 and the first surface 113, and the first inner surface 1161 is disposed opposite to the position-limiting portion 112.

The distance between the second inner surface 1162 and the first surface 113 is greater than the distance between the first inner surface 1161 and the first surface 113, so as to provide a moving space for the elastic buckle 130 when being pressed. The first inner surface 1161 is disposed opposite to the limiting portion 112, and the clamping pin 132 can be pressed by the distance between the first inner surface 1161 and the limiting portion 112, so as to complete the disassembling of the key body 120. In this embodiment, by providing the stepped inner surface 116, the size of the limiting groove 117 can be further reduced on the premise that the limiting groove 117 is used for accommodating the clamping pin 132 and providing a moving space for the elastic buckle 130, thereby preventing the structural strength of the frame body 110 from being reduced due to an excessively large groove.

In the embodiment of the present application, the position-limiting portion 112 extends at least partially between the position-limiting groove 117 and the mounting groove 111. The position-limiting portion 112 may be a protrusion integrally extended from the inner wall of the frame 110, and the protrusion is located between the position-limiting groove 117 and the installation groove 111. Therefore, the limiting portion 112 can be used for being in snap fit with the clamping pin 132, and meanwhile, the limiting portion 112 can support the key body 120 to provide a supporting effect for the key body 120, so that the key body 120 can be reliably fixed in the mounting groove 111, and abnormal phenomena such as falling off and deviation of the key body 120 are avoided.

Referring to fig. 2 and 4, in some embodiments, the latch body 131 includes a first body portion 1311 and a second body portion 1312 integrally formed, one end of the first body portion 1311 is disposed on the key body 120, the other end of the first body portion 1311 is disposed on the second body portion 1312, the locking pin 132 is disposed on the second body portion 1312, and the width of the first body portion 1311 is greater than the width of the second body portion 1312. After the key body 120 is assembled, the first body 1311 is disposed in the mounting groove 111, and the second body 1312 passes through the mounting groove 111 and extends to the limiting groove 117. The width direction of the first body 1311 and the second body 1312 coincides with the longitudinal direction of the housing 110.

The width of the first body 1311 is greater than that of the second body 1312, so that the contact area between the elastic clip 130 and the key body 120 can be increased, and the connection stability between the two parts can be ensured. On the other hand, by reducing the width of the second body 1312, the distance between the stopper 112 and the inner wall of the frame 110 and the size of the disassembly hole 115 and the stopper groove 117 can be reduced accordingly, the structure is more compact, and the structural strength of the frame 110 is prevented from being reduced due to an excessively large opening.

In some embodiments, the latch 132 has a sheet-like structure, and the thickness of the latch 132 is smaller than the width of the second body portion 1312. For example, the thickness of the latch 132 may be 0.3 to 0.5 times the width of the second body portion 1312. Above-mentioned clip 132's thickness is thinner relatively, can be so that clip 132's elasticity is better to can kick-back rapidly and reset after being compressed, also make clip 132 become more easily by the extrusion, conveniently disassemble key main body 120.
