[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] See also Figure 1 The embodiment of the present application provides a smart watch, including a watch case 1, a watch strap 2 and an unlocking piece 4. A screen 20 is provided on one side of the watch case 1; the watch straps 2 are detachably connected to the opposite ends of the watch case 1; the unlocking piece 4 can be movably connected to the watch case 1, and the unlocking piece 4 is used to unlock the watch case 1 and the watch strap 2; wherein, the watch case 1 is provided with a mounting groove 11, and the watch strap 2 is inserted into the mounting groove 11, and the unlocking piece 4 can selectively extend into the mounting groove 11 to unlock the watch strap 2 and the mounting groove 11.

[0031] In actual application, installation grooves 11 are provided at the opposite ends of the watch case 1, and the unlocking piece 4 is movably connected to the watch case 1. Specifically, the unlocking piece 4 can be slidably connected to the watch case 1 and can be selectively extended into the mounting groove 11. When not installed, the strap 2 is separated from the watch case 1. When the strap 2 needs to be installed, the strap 2 is inserted from one side of the mounting groove 11 until the strap 2 is completely located in the mounting groove 11 and locked with the mounting groove 11. At this time, the installation is completed, and because the unlocking piece 4 is not unlocked, the strap 2 cannot be detached from the mounting groove 11, which increases the connection stability between the strap 2 and the watch case 1 and prevents the strap 2 from suddenly falling during use, causing the smart watch to be damaged; when the strap 2 needs to be removed, the unlocking piece 4 is pressed, and the unlocking piece 4 pushes the strap 2 to unlock the mounting groove 11. The user pulls the strap 2 out of the mounting groove 11 to achieve the removal of the strap 2.

[0032] It should be noted that the locking of the strap 2 and the mounting slot 11 can be achieved by snapping or plugging. For example, a snap slot is provided in the mounting slot 11, and the strap 2 is provided with a snap portion. When the strap 2 is inserted into the mounting slot 11, the snap portion extends into the snap slot and snaps into the snap slot. The unlocking member 4 is used to push the snap portion to disengage from the snap slot to achieve unlocking.

[0033] Compared with the prior art, the watch strap 2 of the present application and the mounting slot 11 adopt a plug-in connection method, and the user can quickly and easily connect the watch strap 2 to the watch case 1. At the same time, when the watch strap 2 is inserted into the mounting slot 11, since the watch strap 2 and the mounting slot 11 are in a locked state, the watch strap 2 can be prevented from suddenly falling off during use, thereby increasing the safety of using the smart watch. When the watch strap 2 needs to be replaced or cleaned, the user presses the unlocking piece 4 to disassemble the watch strap 2. It has a simple structure and is easy to operate. It does not increase the overall volume of the smart watch, increases the aesthetics of the device, and greatly satisfies the user's pursuit of personalization.

[0034] See also Figure 2 and Figure 3 The groove wall of the installation groove 11 is provided with a limiting groove 111, the unlocking member 4 is movably arranged in the limiting groove 111, and the strap 2 is provided with a limiting protrusion 25. When the strap 2 is inserted into the installation groove 11, the limiting protrusion 25 extends into the limiting groove 111, and the unlocking member 4 is used to push the limiting protrusion 25 away from the limiting groove 111.

[0035] Specifically, the limiting groove 111 is opened in the installation groove 11 and is connected to the installation groove 11. The unlocking member 4 is slidably connected in the limiting groove 111 and can selectively extend into the installation groove 11. A limiting protrusion 25 is provided on one side of the strap 2 relative to the limiting groove 111. When the strap 2 is inserted into the installation groove 11, the limiting protrusion 25 extends into the limiting groove 111 to limit the movement of the strap 2. On the one hand, it is beneficial to the positioning of the strap 2 and prevents the user from inserting the strap 2 into the installation groove 11 from one end during installation. The excessive movement causes the strap 2 to extend out of the mounting slot 11 from the other end, and the strap 2 cannot be accurately and completely inserted into the mounting slot 11. Therefore, the limiting groove 111 can play a positioning role, so that the strap 2 can be accurately and correctly inserted into the mounting slot 11; on the other hand, the limiting effect of the limiting groove 111 and the limiting protrusion 25 can prevent the strap 2 from being separated from the mounting slot 11 due to external force, thereby increasing the connection stability between the strap 2 and the watch case 1, and when the user is performing strenuous exercise, it can also ensure that the smart watch does not fall off the user's wrist.

[0036] When unlocking is required, the user only needs to press the unlocking member 4, and the unlocking member 4 extends from the limiting groove 111. The unlocking member 4 pushes the limiting protrusion 25 out of the limiting groove 111, releasing the limiting effect of the limiting protrusion 25 and the limiting groove 111, thereby unlocking the locking function of the strap 2 and the installation groove 11, making it convenient for the user to take out the strap 2 for cleaning or replacement.

[0037] It should be noted that in order to facilitate the insertion of the strap 2 into the installation slot 11 and the limiting protrusion 25 can smoothly extend into the limiting slot 111, the strap 2 can be made of a deformable material, such as soft glue or silicone material, so that when the strap 2 is extended into the installation slot 11, the limiting protrusion 25 is squeezed by the groove wall of the installation slot 11 and deformed, which facilitates the strap 2 to smoothly extend into the installation slot 11. When the limiting protrusion 25 is extended to the position opposite to the limiting slot 111, the limiting protrusion 25 returns to its original state and can extend into the limiting slot 111, thereby realizing the locking function of the strap 2 and the installation slot 11.

[0038] It should be noted again that the strap 2 can also be made of a hard material, so that it is easier to insert the strap 2 into the installation slot 11, saving the user's physical strength. At this time, the limiting protrusion 25 can be connected to the strap 2 with an elastic material, and the limiting protrusion 25 can also be elastically connected to the strap 2 so that the limiting protrusion 25 can smoothly extend into the limiting slot 111; this application does not limit the material of the strap 2.

[0039] See again Figure 3 The unlocking member 4 includes an unlocking button 41 and an unlocking portion 42. The unlocking portion 42 is connected to the unlocking button 41. The unlocking portion 42 is located in the limiting groove 111. The unlocking button 41 is slidably connected to the watch case 1 and exposed from the watch case 1. The unlocking portion 42 is used to push the limiting protrusion 25 away from the limiting groove 111.

[0040] In actual application, the unlocking button 41 is slidably connected to the watch case 1 and can slide in the limiting groove 111. One end of the unlocking button 41 extends out of the watch case 1, and the other end is connected to the unlocking part 42. The user presses the end of the unlocking button 41 extending out of the watch case 1 to push the unlocking button 41 to move toward the inside of the watch case 1, thereby driving the unlocking part 42 to extend out of the limiting groove 111. The unlocking part 42 pushes the limiting protrusion 25 out of the limiting groove 111, thereby unlocking the strap 2 and the installation groove 11, making it convenient for the user to remove the strap 2.

[0041] See again Figure 3 The mounting groove 11 includes a groove bottom 112 and a groove opening 113 which are arranged opposite to each other. In the direction from the groove opening 113 to the groove bottom 112 , the mounting groove 11 gradually inclines toward the screen 20 .

[0042] In actual application, the strap 2 needs to be bent and wrapped around the wrist, so the part where the strap 2 is connected to the installation slot 11 will be arched, resulting in a large arc, which will cause the case 1 to be lifted up by the straps 2 at both ends when the strap 2 is arched, so that the case 1 is separated from the user's hand skin. In this way, the case 1 cannot accurately monitor the user's heart rate or pulse, and cannot track and monitor the user's health. Based on this, the installation slot 11 is set at an angle. Specifically, the notch 113 of the installation slot 11 is tilted downward, that is, tilted toward the bottom of the case 1. In this way, when the strap 2 is inserted into the installation slot 11, the strap 2 is tilted downward, tilted toward the bottom of the case 1, that is, tilted toward the user's wrist. Therefore, when the strap 2 is wrapped around the wrist, the connection part between the strap 2 and the installation slot 11 fits the wrist more closely, thereby preventing the case 1 from being arched.

[0043] See also Figure 4 Both ends of the mounting groove 11 are bent and extended toward the screen 20 , and the strap 2 includes a first connecting end 21 , and opposite ends of the first connecting end 21 extend outward, and the first connecting end 21 is adapted to the mounting groove 11 .

[0044] Specifically, both ends of the mounting slot 11 bend and extend toward the screen 20 , that is, extend away from the bottom of the watch case 1 , so that the opening range of the slot 113 can be increased to facilitate the insertion of the first connecting end 21 of the strap 2 .

[0045] See again Figure 4The strap 2 at one end of the watch case 1 includes a second connecting end 22, which is bent and connected to the first connecting end 21. A bending portion 23 is formed at the connection between the second connecting end 22 and the first connecting end 21. The bending portion 23 is provided with a storage hole 24, and the storage hole 24 is used for the strap 2 at the other end of the watch case 1 to pass through.

[0046] The bending portion 23 formed by the first connection end 21 and the second connection end 22 is conducive to the user to distinguish the outside and the inside of the strap 2, so as to facilitate the user to correctly install the strap 2. At the same time, the storage hole 24 opened in the bending portion 23 can be used when the user wears the smart watch. The redundant part of the strap 2 on the other side can be inserted into the storage hole 24, so that the redundant part of the strap 2 can be hidden, which makes the smart watch more beautiful to wear, and prevents the redundant length of the strap 2 from being accidentally bent and squeezed by the user, causing damage to the strap 2.

[0047] It should be noted that the outer side of the watchband 2 refers to the side that does not fit the user's wrist, and the inner side of the watchband 2 refers to the side that fits the user's wrist.

[0048] It can be understood that the structures of the two straps 2 are different. The second connecting end 22 of one strap 2 is provided with a buckle, and the second connecting end 22 of the other strap 2 is provided with a clip hole. When worn, the strap 2 with the clip hole is passed through the storage hole 24, and the buckle is buckled with one of the clip holes to complete the wearing of the smart watch.

[0049] See also Figure 5 The smart watch includes a power button 3 and a knob button 6. The knob button 6 and the power button 3 are connected to the same side of the watch case 1. The knob button 6 is movably connected to the watch case 1. The knob button 6 is used to control the zoom of the screen 20.

[0050] In actual application, the power key 3 is used as a physical switch to start the smart watch. Specifically, the user can long press the power key 3, and the power key 3 sends a start signal to the mainboard inside the smart watch. The mainboard controls the power supply to supply power to the electrical components inside the smart watch to start the smart watch. The knob button 6 is used to adjust the size of the screen 20 during use, so that the user can read the information displayed on the screen 20 more accurately. The knob button 6 provides an intuitive and easy-to-operate method. The user can browse the information on the screen 20 by rotating it, which is different from directly controlling by touching the screen 20. The rotating button can reduce misoperation caused by mistouch during exercise or in a humid environment, and can protect the screen 20.

[0051] It can be understood that the movable connection between the knob button 6 and the watch case 1 means that the knob button 6 can rotate relative to the watch case 1 and can also move relative to the watch case 1.

[0052] See again Figure 5The smart watch includes a camera 7, which is connected to a knob button 6. The knob button 6 can move relative to the watch case 1. When the knob button 6 moves away from the watch case 1, the camera 7 is exposed from the watch case 1; the knob button 6 can rotate relative to the watch case 1 to drive the camera 7 to rotate.

[0053] In order to provide convenience, existing smart watches usually integrate payment functions, so smart watches need to be equipped with cameras 7 for users to scan code payment operations. Based on this, the present application integrates the camera 7 on the knob button 6, and the knob button 6 can move relative to the watch case 1. When the knob button 6 is pulled out of the watch case 1, the camera 7 is exposed, and the user can rotate the knob button 6 to drive the camera 7 to rotate, so that the camera 7 can perform code scanning operations.

[0054] See also Figure 6 The side of the watch case 1 extends outward to form a protective protrusion 12 , and the protective protrusion 12 is provided with a first key slot 13 and a second key slot 14 . The switch key 3 is embedded in the first key slot 13 , and the knob button 6 is embedded in the second key slot 14 .

[0055] In actual application, a protective protrusion 12 is provided on the side of the watch case 1. The protective protrusion 12 is mainly used by the switch key 3 and the knob button 6. The switch key 3 is embedded in the first key slot 13, and the knob button 6 is embedded in the second key slot 14. In this way, when the smart watch collides, the protective protrusion 12 can prevent the switch key 3 and the knob button 6 from being impacted by the outside, thereby improving the safety protection function of the smart watch.

[0056] See again Figure 6 The smart watch also includes a card inserting component 8. The watch case 1 is provided with a slot 15. The slot 15 and the mounting slot 11 are provided on the same side of the watch case 1, and the slot 15 is located above the mounting slot 11. The card inserting component 8 is inserted into the slot 15, and the card inserting component 8 is used to install a phone card.

[0057] Smart watches usually also have a call function, so a slot 15 is set on the side of the smart watch. Specifically, when the smart watch is worn on the wrist, the installation slots 11 at both ends of the smart watch are close to the user's body at one end. The installation slot 11 at the other end is far away from the user's body, and the installation slot 11 on the side close to the user's body is set as the lower installation slot 11. The slot 15 and the lower installation slot 11 are set on the same side of the watch case 1, which makes it convenient for the user to take out the card insertion component 8 when using it. The card insertion function can be realized without taking the smart watch off the wrist, which improves the convenience of using the smart watch.

[0058] See also Figure 7The smart watch also includes a function button 9, which is connected to a side of the watch case 1 adjacent to the screen 20. The function button 9 is electrically connected to the screen 20 and is used to control the screen 20 to confirm or return. The user can select the corresponding application or function by pressing the function button 9. This operation can prevent the user from touching the screen 20 with wet hands, thereby preventing the screen 20 from getting wet and causing damage to the internal circuit of the smart watch.

[0059] See also Figure 8 The smart watch also includes a charging unit 10, and the charging unit 10 and the screen 20 are respectively connected to opposite sides of the watch case 1, so that the smart watch can be easily charged.

[0060] Different from the prior art, the embodiment of the present application provides a smart watch, including a watch case 1, a strap 2 and an unlocking piece 4. A screen 20 is provided on one side of the watch case 1; the straps 2 are detachably connected to the opposite ends of the watch case 1; the unlocking piece 4 can be movably connected to the watch case 1, and the unlocking piece 4 is used to unlock the watch case 1 and the strap 2; wherein, the watch case 1 is provided with a mounting groove 11, and the strap 2 is inserted into the mounting groove 11, and the unlocking piece 4 can selectively extend into the mounting groove 11 to unlock the strap 2 and the mounting groove 11. Compared with the prior art, the watch strap 2 of the present application and the mounting slot 11 adopt a plug-in connection method, and the user can quickly and easily connect the watch strap 2 to the watch case 1. At the same time, when the watch strap 2 is inserted into the mounting slot 11, since the watch strap 2 and the mounting slot 11 are in a locked state, the watch strap 2 can be prevented from suddenly falling off during use, thereby increasing the safety of using the smart watch. When the watch strap 2 needs to be replaced or cleaned, the user presses the unlocking piece 4 to disassemble the watch strap 2. It has a simple structure and is easy to operate. It does not increase the overall volume of the smart watch, increases the aesthetics of the device, and greatly satisfies the user's pursuit of personalization.

[0061] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
