Description

Technical Field

[0001] The utility model relates to the technical field of wearable devices, and more specifically, to a button assembly for a wearable device. Background Art

[0002] The button assembly in a wearable device is an important part for users to interact with the device. These buttons can be used to control various functions of the device, such as power on / off, setting adjustment, starting applications, measuring health data, navigating menus, etc. In different wearable devices, the design and functions of the button assembly may vary, but their core purpose is to provide an interaction interface between the user and the device.

[0003] Existing button assemblies are mostly traditional mechanical buttons that trigger internal switches through physical contact. When pressed, they trigger microswitches. They provide direct tactile feedback and are suitable for use in various environments. The button caps are usually made of plastic, silicone, or metal, and the internal switches may use conductive materials such as metal contact points or carbon ink, which is one of the most common types.

[0004] In the actual use process of the prior art, since there is usually a gap between the button and the outer shell of the wearable device, water vapor and impurities in the external environment easily enter the interior of the wearable device through the gap, affecting the normal use of the button and the performance of other electronic components. Therefore, a button assembly for a wearable device is proposed. Content of the Utility Model

[0029] Refer to Figures 1-4 , which is the first embodiment of the present utility model. This embodiment provides a button assembly for a wearable device, including a wearable device housing 1. A detachable component 2 is arranged in the inner cavity of the wearable device housing 1, including a button inner frame 201 movably connected in the inner cavity of the wearable device housing 1. An outer rubber sleeve 202 is fixedly connected to one side of the button inner frame 201. Sealing gaskets 205 are arranged in both the button inner frame 201 and the inner cavity of the wearable device housing 1.

[0030] Specifically, a device main body 101 is installed in the inner cavity of the wearable device housing 1. An internal switch contact 102 is arranged on one side of the device main body 101. The pressing rod 303 and the internal switch contact 102 are on the same horizontal line. The outer rubber sleeve 202 is made of flexible rubber material. Connecting plates 203 are symmetrically and fixedly connected to the outer surface of the button inner frame 201. The connecting plates 203 are fixedly connected to the wearable device housing 1 through cooperation with bolts 204. The sealing gasket 205 has a hollow internal structure, and a magnet 206 is embedded in its inner cavity. The magnet 206 located inside the wearable device housing 1 is the north pole, and the magnet 206 located inside the button inner frame 201 is the south pole.

[0031] Furthermore, the button inner frame 201 is placed into the opening on the side of the wearable device housing 1, and then the connecting plates 203 and the button inner frame 201 are fixedly installed on the wearable device housing 1 through bolts 204. Since the button inner frame 201 is a separate part and can be directly removed without opening the housing, it is convenient for the operator to perform maintenance and replacement. Compared with the traditional method of disassembling the housing for maintenance, the operation is simpler and more convenient. At this time, the sealing gaskets 205 in the button inner frame 201 and the inner cavity of the wearable device housing 1 are closely attached together to play a sealing role, and the two sealing gaskets 205 are firmly adsorbed and attached together by the attraction of two magnets 206 with different magnetic poles, ensuring the installation of the sealing plate and preventing water vapor and impurities from entering the inside of the wearable device housing 1.

[0032] Embodiment 2

[0033] Refer to Figures 1-4, which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. A key assembly 3 is arranged in the inner cavity of the detachable component 2, including a pressing block 301 fixedly connected to the inner cavity of the outer rubber sleeve 202, a limiting plate 302 fixedly connected to the inner cavity of the key inner frame 201, and a pressing rod 303 inserted through the inner cavity of the limiting plate 302.

[0034] Specifically, one end of the pressing block 301 and the pressing rod 303 are fixedly connected. Two telescopic rods 304 are symmetrically and fixedly connected between the limiting plate 302 and the pressing block 301. A spring 305 is sleeved on the outer surface of the telescopic rod 304, and both ends of the spring 305 are fixedly connected to the pressing block 301 and the limiting plate 302 respectively.

[0035] Furthermore, when the pressing block 301 is pressed inward to compress the telescopic rod 304 and the spring 305, the soft outer rubber sleeve 202 deforms accordingly. When the pressing block 301 moves inward, it drives the pressing rod 303 to move in a limited manner within the inner cavity of the limiting plate 302. When the pressing rod 303 contacts the internal switch contact 102, the two metal contacts come into contact, thereby turning on the signal. When released, the spring 305 drives the pressing rod 303 to return to its original state by its own elastic force, and at this time, the contacts are separated and the circuit is disconnected. The pressing rod 303 is made of metal and is provided with corresponding metal contacts together with the internal switch contact 102.

[0036] Working principle: During the use of the device, the operator places the key inner frame 201 into the opening on the side of the wearable device housing 1, and then fixedly installs the connecting plate 203 and the key inner frame 201 on the wearable device housing 1 through bolts 204. Since the key inner frame 201 is a separate part and can be directly removed without opening the housing, it is convenient for the operator to perform maintenance and replacement. Compared with the traditional method of disassembling the housing for maintenance, the operation is simpler and more convenient. At this time, the key inner frame 201 is closely attached to the sealing gasket 205 inside the wearable device housing 1 to play a sealing role, and the two sealing gaskets 205 are firmly adsorbed and attached together by two magnets 206 with different magnetic poles to ensure the installation of the sealing plate and prevent water vapor and impurities from entering the inside of the wearable device housing 1. When in use, the pressing block 301 is pressed inward to compress the telescopic rod 304 and the spring 305, and the soft outer rubber sleeve 202 deforms accordingly. When the pressing block 301 moves inward, it drives the pressing rod 303 to move in a limited manner within the inner cavity of the limiting plate 302. When the pressing rod 303 contacts the internal switch contact 102, the two metal contacts come into contact, thereby turning on the signal. When released, the spring 305 drives the pressing rod 303 to return to its original state by its own elastic force, and at this time, the contacts are separated and the circuit is disconnected. The pressing rod 303 is made of metal and is provided with corresponding metal contacts together with the internal switch contact 102.
