DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present application.

[0037] The positional nouns such as “upper”, “lower”, “lateral” and the like involved in the embodiments of the present application are generally taken with reference to the drawings. Figure 1The relative relationship of the orientations shown in the figures is taken as a reference, and these orientation terms are used only for more clearly describing the structure and the relationship between structures, and are not used to describe absolute orientations. When the product is placed in different postures, the orientations may change, for example, "upper" and "lower" may be interchanged.

[0038] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by one of ordinary skill in the art.

[0039] In the related art, as shown in Figure 1 The key assembly mainly includes a key cap 100 and a key rod 200. The key rod 200 is connected to the key cap 100 by adhesive 300. The end surface of the key rod 200 is exposed to form a top pressing surface of the key assembly. In order to ensure the strength of the key rod 200, the key rod 200 is usually made of a metal material with high strength such as stainless steel or titanium alloy. This leads to limitations in modeling and texture of the key assembly, and it is difficult to meet the diversified and personalized needs of users for the appearance of the key assembly.

[0040] To solve the above technical problems, the present application provides a key assembly and an electronic device.

[0041] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0042] As shown in Figure 2 The key assembly provided by the embodiments of the present application includes a key cap 1, a key rod 2, and a key decoration 3.

[0043] The key assembly is applied to an electronic device. The electronic device can be a mobile phone, a notebook computer, a tablet computer, an e-book reader, a navigator, a palm game console, a virtual and real device, an augmented reality device, and the like. In particular, the electronic device can be a smart watch, a smart bracelet, smart glasses, and the like. The present application takes the key assembly applied to a smart watch as an example for description.

[0044] The key cap 1 has a through hole 11. As shown in Figure 2 and Figure 6 The key cap 1 is substantially in the shape of a cylindrical shell. A plurality of grooves 13 are arranged on the outer wall of the key cap 1 and spaced apart in the circumferential direction of the key cap 1. The grooves 13 are used to increase the friction between the key cap 1 and a human hand, so that the user can more easily rotate the key assembly.

[0045] As shown in Figure 2As shown, the key rod 2 comprises a rod head 21 and a rod body 22 connected with each other, and the rod head 21 is installed in the through hole 11. The key rod 2 is substantially in the shape of a "T" character, the outer diameter of the rod head 21 is larger than that of the rod body 22, and the rod body 22 is provided with a threaded structure for cooperating with a nut inside the electronic device to realize the installation and fixation of the key assembly.

[0046] Exemplarily, the key rod 2 is a metal piece with high strength and hardness to prevent deformation or fracture when the key assembly is pressed or pulled.

[0047] The key decoration piece 3 is in the shape of a sheet, is located on the side of the rod head 21 away from the rod body 22 and covers the side opening of the through hole 11 of the key cap 1, and the key decoration piece 3 and the key cap 1 jointly play a decoration role. Since the key decoration piece 3 covers the key rod 2 and constitutes the top pressing surface of the key assembly, the top pressing surface of the key assembly is no longer limited to metal materials, but has more choices in terms of material and form, which facilitates to meet the diversified needs of users.

[0048] The key assembly provided by the embodiment of the present application covers the key decoration piece 3 on one side opening of the through hole 11, so that the key rod 2 is covered by the key decoration piece 3, thereby constituting the top pressing surface of the key assembly by the key decoration piece 3, and the key rod 2 is not exposed. Therefore, the appearance of the top pressing surface of the key assembly is no longer limited by the appearance of the key rod 2, but different kinds of key decoration pieces 3 can be selected to constitute different appearances, so that the appearance of the key assembly has more choices and possibilities, greatly expands the appearance richness of the key assembly, is beneficial to meet the different modeling needs of users for the key assembly, and improves the use experience of users.

[0049] In a further embodiment, as Figure 3 shown, the rod head 21 comprises a main body part 211 and an outer edge part 212 connected with each other, the main body part 211 is connected with the rod body 11, specifically, the main body part 211 is perpendicular to the extension direction of the rod body 22 and is coaxially connected with the rod body 22. The outer edge part 212 is annular and located at the edge of the main body part 211. The inner wall of the through hole 11 is provided with an internal thread 111, and the outer wall of the outer edge part 212 is provided with an external thread 2121 matched with the internal thread 111, and the key rod 2 is connected with the key cap 1 through the internal thread 111 and the external thread 2121.

[0050] In the prior art, as Figure 1As shown, the keycap 100 and the key stem 200 are connected by the glue 300 along the length direction of the key stem 200, the inner wall of the through hole of the keycap 100 serves as a functional part and can cooperate with the element such as the barb tube of the electronic device, the keycap 100 and the key stem 200 need to ensure a certain concentricity, otherwise, in the process of rotating the keycap 100 around the barb tube, the key stem 200 is prone to be stuck, which affects the rotation damping and smooth rotation of the key assembly. The assembly concentricity of the keycap 100 and the key stem 200 is high, and the precision of the assembly equipment and the clamp jig and the process control requirement are also high. The glue 300 needs to be preserved by the pressure jig in multiple directions during the dispensing and solidification process, so that the assembly cost of the key assembly is high and the assembly efficiency is low.

[0051] In the embodiment of the present application, the outer edge part 212 replaces the functional part of the keycap 100 in the prior art, and the inner side of the outer edge part 212 can cooperate with the element such as the barb tube of the electronic device. Since the main body part 211 is coaxially connected with the stem body 22, in the process of rotating the outer edge part 212 around the barb tube, the stem body 22 also naturally rotates coaxially. That is, to ensure the smooth rotation of the key assembly, the key assembly provided by the embodiment of the present application only needs to be made into the coaxially connected stem body 22 and main body part 211 by turning process, without the need for additional assembly equipment to meet the concentricity assembly requirement between the keycap 1 and the key stem 2, thereby reducing the assembly precision requirement of the key assembly and being beneficial to improving the assembly efficiency of the key assembly.

[0052] In addition, the key stem 200 in the prior art has a complex structure and a long CNC (Computerized Numerical Control) processing time, which increases the production cost. However, the key stem 2 provided by the embodiment of the present application has a low machining precision requirement and a short CNC processing time, which is beneficial to reducing the production cost and improving the production efficiency.

[0053] Further, an adhesive is arranged between the stem head 21 and the keycap 1.

[0054] Exemplarily, the adhesive is a thread glue, also known as anaerobic glue, which can be used for bonding and sealing.

[0055] By adding the adhesive between the stem head 21 and the keycap 1, the loosening of the threaded connection between the stem head 21 and the keycap 1 can be prevented, and the connection stability and sealing property between the key stem 2 and the keycap 1 are improved.

[0056] Further, as shown in Figure 6 At least part of the internal thread 111 is discontinuously distributed in the circumferential direction to form at least one first opening 112 for accommodating the adhesive; and / or, as shown in Figure 4As shown, at least a portion of the external thread 2121 is discontinuously distributed in the circumferential direction to form at least one second opening 2122 for receiving adhesive.

[0057] The internal thread 111 can be distributed intermittently along the circumference of the button cap 1 in every turn, or only some turns can be distributed intermittently along the circumference of the button cap 1; similarly, the external thread 2121 can be distributed intermittently along the circumference of the button rod 2 in every turn, or only some turns can be distributed intermittently along the circumference of the button rod 2.

[0058] like Figure 5 As shown, the internal thread 111 is provided with two first openings 112, which are arranged opposite each other in the radial direction of the keycap 1 and extend in the axial direction of the keycap 1; exemplarily, the external thread 2121 is provided with two second openings 2122, which are arranged opposite each other in the radial direction of the key rod 2 and extend in the axial direction of the key rod 2.

[0059] By setting the internal thread 111 and / or the external thread 2121 as a broken thread structure, more adhesive can be accommodated through the first opening 112 and / or the second opening 2122, increasing the contact area between the thread and the adhesive, and further improving the connection stability and sealing between the button rod 2 and the button cap 1.

[0060] In one embodiment, the button decoration 3 is bonded to the button cap 1.

[0061] like Figure 3 As shown, the button decorative part 3 is separated from the button rod 2 and fixed to the button cap 1 by adhesive dispensing. In the prior art, the button cap 100 and the button rod 200 are only connected by adhesive bonding. In order to ensure the concentricity of the button cap 1 and the button rod 2, the adhesive 300 needs to be pressurized in multiple directions using a pressure-holding fixture during dispensing and curing, which requires high precision. However, in this embodiment, since the button rod 2 and the button cap 1 are threadedly connected, during the dispensing and curing of the button decorative part 3 and the button cap 1, only pressure control along the axial direction of the button cap 1 is required, which reduces the precision requirement and helps to reduce production costs.

[0062] In one embodiment, the button decoration 3 is connected to the rod head 21.

[0063] In this embodiment, by connecting the button decoration 3 to the rod head 21, the additional step of assembling the button decoration 3 and the button cap 1 is eliminated, which helps to reduce the processing steps of the button assembly and improve assembly efficiency.

[0064] In one embodiment, the button lever 2 is made of stainless steel or titanium alloy.

[0065] By setting the key rod 2 as a stainless steel or titanium alloy part with high strength, deformation or breakage of the key rod 2 when the key assembly is pressed or pulled can be prevented, and the service life of the key assembly is improved.

[0066] In one embodiment, the key decoration 3 is one of a metal part, a gem mineral part, a glass part, or a ceramic part, or a combination of two or more thereof.

[0067] Illustratively, the key decoration 3 is made of one or more of stainless steel, titanium alloy, aluminum alloy, sapphire, glass, crystal, or ceramic, and the material and form can be selected in various ways to meet the diversified and personalized needs of users for the appearance of the key assembly.

[0068] Optionally, the key cap 1 is one of a metal part, a gem mineral part, a glass part, or a ceramic part, or a combination of two or more thereof, and the material of the key cap 1 can be the same as or different from that of the key decoration 3, which can be selected according to actual needs.

[0069] In one embodiment, an inner edge of an end of the key cap 1 away from the key decoration 3 is provided with an inward flange 12, and an end face of an end of the rod head 21 away from the key decoration 3 is at least partially covered by the inward flange 12.

[0070] As shown in Figure 3 and Figure 6 , the inward flange 12 is annular and located at one end of the key cap 1, and the inward flange 12 can cover at least part of an end face of an end of the rod head 21 close to the inward flange 12.

[0071] With this arrangement, the key rod 2 can be fully ensured not to be exposed, the appearance consistency of the key assembly is improved, and the junction between the key cap 1 and the key rod 2 is prevented from being exposed in the case where the materials or colors of the key cap 1 and the key rod 2 are different, thereby affecting the aesthetic appearance of the key assembly.

[0072] The embodiments of the present application also provide an electronic device including the key assembly provided by any of the above embodiments.

[0073] Specifically, the electronic device can be a mobile phone, a notebook computer, a tablet computer, an e-book reader, a navigator, a palm game console, a virtual and reality device, an augmented reality device, or the like having a key.

[0074] Further, the electronic device is a smart wearable device, and specifically can be a smart watch, a smart bracelet, smart glasses, or the like.

[0075] In the present application, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance. The term "multiple" means two or more, unless otherwise explicitly limited.

[0076] Other embodiments of the application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. It is intended that the application cover any and all variations of the application that come within the scope of the
