Description

Technical Field

[0001] This utility model relates to the field of watch technology, specifically to an electronic watch. Background Technology

[0002] Due to their highly integrated nature, smartwatches have an extremely compact internal layout. The watch encoder, as a core human-computer interaction component enabling button functions, directly affects the overall user experience and performance of the device through its stable and reliable installation.

[0003] The encoder in existing smartwatches is placed in a specific location on the bottom case and secured using a steel stamping fixture. Because the encoder, along with critical components such as the battery and motherboard, is housed within the limited space of the bottom case, during assembly or prolonged use, slight battery expansion or external impact can easily cause pressure or contact interference between the battery or motherboard and the encoder. This can lead to accidental encoder activation or poor internal contact, resulting in serious problems such as malfunctioning button signals and unexplained automatic watch restarts, significantly impacting product reliability. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an electronic watch that, by setting conductive foam, can absorb and buffer the impact force generated on the encoder when the battery squeezes the positioning frame, prevent rigid impact from being directly transmitted to the encoder, ensure the stability of the encoder operation, and reduce the risk of false triggering.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An electronic watch includes a back case, a display screen, a motherboard, a battery, buttons, and an encoder. The motherboard and the battery are disposed inside the back case. The display screen is connected to the motherboard. The buttons are connected to the motherboard via the encoder. A positioning frame is snapped onto the back case to fix the encoder. The positioning frame is located on one side of the battery. Conductive foam is disposed between the positioning frame and the encoder to cushion the impact force on the encoder when the battery squeezes the positioning frame.

[0007] As a further improvement to the above technical solution, two positioning buffer parts are provided on the bottom shell, and the positioning frame is snapped onto the two positioning buffer parts. The two positioning buffer parts are used to limit the two sides of the encoder respectively.

[0008] As a further improvement to the above technical solution, each of the two positioning buffer parts is provided with a snap-fit ​​protrusion on its opposite side, and the positioning frame has two slots, which respectively cooperate with the two snap-fit ​​protrusions.

[0009] As a further improvement to the above technical solution, the positioning buffer includes a silicone block.

[0010] As a further improvement to the above technical solution, a conductive adhesive layer is provided on one side of the conductive foam, and the conductive adhesive layer is adhered to the side of the positioning frame facing the encoder.

[0011] As a further improvement to the above technical solution, a conductive cloth is pasted on the surface of the battery, and the conductive adhesive layer is pasted on the conductive cloth.

[0012] As a further improvement to the above technical solution, the thickness of the conductive foam is 0.3-0.8mm.

[0013] As a further improvement to the above technical solution, the positioning frame is integrally stamped from a steel sheet.

[0014] As a further improvement to the above technical solution, at least two limiting blocks are provided on the bottom shell, and the two limiting blocks are used to limit the side of the battery close to the encoder.

[0015] As a further improvement to the above technical solution, the side wall of the bottom shell is provided with a through hole, and the button includes a keycap, a connecting post, a spring and a blocking block. The keycap is connected to one end of the connecting post, the spring is sleeved on the connecting post, the other end of the connecting post passes through the through hole and is connected to the encoder, the blocking block is disposed on the connecting post and abuts against the inner wall of the bottom shell, and the two ends of the spring abut against the keycap and the outer wall of the bottom shell respectively.

[0016] The beneficial effects of this utility model are as follows: This utility model provides an electronic watch that, by setting a positioning frame, provides an independent and stable installation space for the encoder, avoiding displacement or shaking of the encoder when the button is pressed. At the same time, by setting conductive foam between the positioning frame and the encoder, the conductive foam, which has good elasticity and compressibility, can absorb and buffer the impact force on the encoder when the battery exerts pressure on the positioning frame due to slight expansion or assembly tolerance, preventing rigid impact from being directly transmitted to the encoder, ensuring the stability of the encoder's operation, and reducing the risk of false triggering.

Detailed Implementation

[0025] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0026] Reference Figures 1 to 6 An example of this utility model provides an electronic watch, including a bottom case 100, a display screen 110, a main board 120, a battery 130, a button 140, and an encoder 150. The main board 120 and the battery 130 are disposed inside the bottom case 100. The display screen 110 is connected to the main board 120. The button 140 is connected to the main board 120 through the encoder 150. A positioning frame 160 is snapped onto the bottom case 100. The positioning frame 160 is used to fix the encoder 150. The positioning frame 160 is located on one side of the battery 130. A conductive foam 170 is disposed between the positioning frame 160 and the encoder 150. The conductive foam 170 is used to buffer the impact force generated on the encoder 150 when the battery 130 squeezes the positioning frame 160.

[0027] Understandably, by setting up the positioning frame 160, an independent and stable installation space is provided for the encoder 150, preventing the button 140 from displacing or shaking the encoder 150 when pressed. At the same time, by setting up the conductive foam 170, which has good elasticity and compressibility, when the battery 130 exerts pressure on the positioning frame 160 due to slight expansion or assembly tolerance, the conductive foam 170 can absorb and buffer the impact force generated on the encoder 150 when the battery 130 squeezes the positioning frame 160, preventing rigid impact from being directly transmitted to the encoder 150, ensuring the stability of the encoder 150's operation, and reducing the risk of false triggering.

[0028] In some preferred embodiments, the bottom shell 100 is provided with two positioning buffers 180, and the positioning frame 160 is snapped onto the two positioning buffers 180. The two positioning buffers 180 are respectively used on both sides of the limit encoder 150.

[0029] Understandably, on the one hand, the two positioning buffers 180 can precisely limit the encoder 150 and the positioning frame 160, ensuring the accuracy of the installation position of the encoder 150 and the positioning frame 160. On the other hand, the two positioning buffers 180 can also absorb and buffer the lateral impact and vibration of the internal parts on the encoder 150, ensuring the stability of the encoder 150.

[0030] Furthermore, each of the two positioning buffer parts 180 has a snap-fit ​​protrusion 181 on its opposite side, and the positioning frame 160 has two slots 161, which respectively engage with the two snap-fit ​​protrusions 181.

[0031] Understandably, during installation, simply inserting the two slots 161 of the positioning frame 160 into the two latching protrusions 181 will complete the fixing of the positioning frame 160. Installation and disassembly are simple and quick, improving assembly efficiency and facilitating maintenance. At the same time, the secure installation of the positioning frame 160 ensures that it will not come loose when the watch vibrates or swings.

[0032] Specifically, the positioning buffer 180 includes a silicone block, which has good elasticity and flexibility, and can effectively absorb and disperse external impact forces to ensure the buffering effect.

[0033] In some preferred embodiments, a conductive adhesive layer 171 is provided on one side of the conductive foam 170. The conductive adhesive layer 171 is adhered to the side of the positioning frame 160 facing the encoder 150. The conductive adhesive layer 171 firmly adheres the conductive foam 170 to the positioning frame 160, preventing the positioning frame 160 from shifting or falling off when the watch swings, vibrates or falls.

[0034] In some preferred embodiments, a conductive cloth 190 is adhered to the surface of the battery 130, and a conductive adhesive layer 171 is adhered to the conductive cloth 190.

[0035] Understandably, the conductive cloth 190 on the surface of the battery 130 is connected to the conductive foam 170 on the positioning frame 160, which can transfer the static electricity on the encoder 150 to the ground wire of the battery 130 through the conductive foam 170 and the conductive cloth 190. This improves the watch's anti-static capability and avoids the impact of static electricity on the encoder 150 on the circuit of the main board 120.

[0036] Furthermore, the thickness of conductive foam 170 is 0.3-0.8 mm.

[0037] Understandably, a thickness of less than 0.3mm will result in insufficient buffer space, affecting the buffering and conductivity effects, while a thickness greater than 0.8mm will excessively occupy the internal space of the limit frame, making it difficult to install the encoder 150.

[0038] By setting the thickness of the conductive foam 170 to 0.3-0.8mm, it is possible to ensure that the conductive foam 170 provides sufficient deformation within a limited space, thereby ensuring that it can buffer external impacts and maintain stable contact pressure.

[0039] In some preferred embodiments, the positioning frame 160 is integrally stamped from a steel sheet.

[0040] On the one hand, steel sheets have high strength and rigidity, and the one-piece stamped positioning frame 160 has no splicing gaps, which can improve the overall structural strength of the positioning frame 160 and prevent deformation due to external impact. On the other hand, one-piece stamping can achieve mass production, effectively control production costs, and ensure good consistency.

[0041] In some preferred embodiments, at least two limiting blocks 200 are provided on the bottom shell 100, which are used to limit the side of the battery 130 close to the encoder 150.

[0042] Understandably, even if the battery 130 expands due to aging or generates huge thrust under extreme conditions, the limit block 200 can act as a hard limit to prevent the battery 130 from moving toward the encoder 150 side, thus avoiding a large impact on the positioning frame 160.

[0043] In some preferred embodiments, the side wall of the bottom shell 100 is provided with a through hole, and the button 140 includes a keycap 141, a connecting post 142, a spring 143 and a blocking block 144. The keycap 141 is connected to one end of the connecting post 142, the spring 143 is sleeved on the connecting post 142, the other end of the connecting post 142 passes through the through hole and is connected to the encoder 150, the blocking block 144 is disposed on the connecting post 142 and abuts against the inner wall of the bottom shell 100, and the two ends of the spring 143 abut against the keycap 141 and the outer wall of the bottom shell 100, respectively.

[0044] Understandably, when a user presses the keycap 141, the keycap 141 pushes the connecting post 142, causing the connecting post 142 to move towards the encoder 150. The end of the connecting post 142 presses the trigger mechanism of the encoder 150, causing the encoder 150 to generate a corresponding signal and transmit it to the motherboard 120. The processor on the motherboard 120 receives and recognizes the signal, executes the preset instruction, and outputs the execution result to the display screen 110. Simultaneously, during the pressing process, the spring 143 is compressed between the keycap 141 and the outer wall of the bottom shell 100, providing gradually increasing resistance and achieving a good pressing feel. When the user releases the keycap 141, the compressed spring 143 releases its elasticity, pushing the keycap 141 and the connecting post 142 outwards until the blocking block 144 abuts against the inner wall of the bottom shell 100, resetting the action and awaiting the next trigger.

[0045] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
