[0031] Figure 1 This is a schematic diagram of a self-locking hook structure for a smart wearable device provided in an embodiment of this application; as shown below. Figure 1As shown, the self-locking hook structure for smart wearable devices includes a base self-locking structure 1 and a smart wearable device unlocking structure 2, as detailed below:

[0032] like Figure 2 As shown, Figure 2 This is a schematic diagram of the self-locking base structure provided in an embodiment of this application.

[0033] In one embodiment, the base self-locking structure 1 includes a locking tongue 10, an elastic element 11, and a locking tongue groove 12.

[0034] Specifically, the latch 10 includes a latch spring positioning groove 101 and a latch block 102, wherein the latch spring positioning groove 101 and the latch block 102 are an integral structure, and the latch block 102 is located on the side above the latch spring positioning groove 101.

[0035] Specifically, the locking tongue block 102 has an inclined surface.

[0036] Specifically, there are two locking tongues 10, which are divided into a left locking tongue and a right locking tongue based on their positions in the self-locking structure 1 of the base. The left locking tongue and the right locking tongue are mirror images of each other. In the left locking tongue, the opening of the corresponding left locking tongue spring positioning groove 101 faces to the right, and the left locking tongue block 102 is located on the upper left side of the left locking tongue spring positioning groove 101. In the right locking tongue, the opening of the corresponding right locking tongue spring positioning groove 101 faces to the left, and the right locking tongue block 102 is located on the upper right side of the right locking tongue spring positioning groove 101.

[0037] Specifically, the elastic element 11 is a spring.

[0038] Specifically, the latch groove 12 includes a spring baffle 120 and a latch sliding limit plate 121; wherein the spring baffle 120 and the latch sliding limit plate 121 form a right angle structure, and the latch sliding limit plate 121 is located above the spring baffle 120.

[0039] Specifically, the latch groove 12 further includes a latch baffle 122, wherein the latch baffle 122 is parallel to the spring baffle 120, and the distance between the latch baffle 122 and the spring baffle 120 forms a space within the latch groove 12 for the latch to slide laterally.

[0040] Specifically, the latch block 102 and the latch sliding limit plate 121 are located above the latch spring positioning groove 101. The latch block 102 is also located above the latch baffle 122, and the latch block 102 and the latch baffle 122 form a right angle structure at the connection point outside the latch groove 12.

[0041] Specifically, the latch block 102 and the latch sliding limit plate 121 are at the same height.

[0042] Specifically, the first end of the elastic element 11 is placed in the locking tongue spring positioning groove 101, and the second end of the elastic element 11 is in contact with the spring baffle 120.

[0043] Specifically, there are also two locking tongue grooves 11. Based on the position of the locking tongue grooves 11 in the self-locking structure 1 of the base, they are divided into a left locking tongue groove 11 and a right locking tongue groove 11; wherein, the left locking tongue groove 11 and the locking tongue groove 11 are mirror images of each other.

[0044] In one embodiment, the base self-locking structure 1 further includes: a base main shell 13 and a base decorative cover plate 14, such as... Figure 3 As shown, Figure 3 This is another structural schematic diagram of the base self-locking structure provided in the embodiments of this application.

[0045] Specifically, the base main shell 13 is provided with a component recess 130, and the locking tongue 10 and the elastic element and the locking tongue groove are placed in the component recess 130.

[0046] Specifically, the base decorative cover plate 14 is placed above the device recess 130, and the base decorative cover plate 14 is connected to the base main shell 13 by ultrasonic welding.

[0047] The self-locking structure 1 of the base provided in this embodiment is illustrated as follows: The first end of the elastic element 11 is placed into the latch spring positioning groove 101 of the latch 10, and then the elastic element 11 is compressed, and the latch 10 and the elastic element 11 are placed together into the latch groove 12, which is located in the base main shell 13. The elastic element 11 is released, so that the first end of the elastic element 11 abuts against the latch spring positioning groove 101 of the latch 10, and the second end of the elastic element 11 abuts against the spring baffle 120 in the latch groove 12. At this time, the connection between the latch block 102 of the latch 10 and the latch baffle 122 forms a right angle structure outside the latch groove 12, so that the latch 10 is in a locked state. Finally, the base decorative cover plate 14 is placed on the base main shell 13 and connected by ultrasonic welding process to prevent the latch 10 from falling off during use.

[0048] like Figure 4 As shown, Figure 4 This is a schematic diagram of the unlocking structure of the smart wearable device provided in an embodiment of this application.

[0049] In one embodiment, the smart wearable device unlocking structure 2 includes an unlocking button 20.

[0050] In one embodiment, the smart wearable device unlocking structure 2 further includes: a button spring 21 and a host 22.

[0051] Specifically, the outer side of the host 22 is provided with an unlock button recess 220, the bottom of the unlock button recess 220 is provided with a spring positioning post 221, the first end of the unlock button 20 is provided with a button spring positioning hole 200; the first end of the button spring 21 is placed in the button spring positioning hole 200, the second end of the button spring 21 is placed on the spring positioning post 221, and the second end of the unlock button 20 is exposed on the outer side of the host 22.

[0052] Specifically, the number of the unlock button 20, the unlock button recess 220, and the button spring 21 is 2.

[0053] Specifically, two unlock button recesses 220 are respectively located on the left and right outer sides of the main unit 22. The two unlock button recesses 220 are used to place the unlock button 20 and the button spring placed on the unlock button 20.

[0054] In one embodiment, the smart wearable device unlocking structure 2 further includes a locking tongue plate 23.

[0055] Specifically, the host 22 is provided with a buckle recess 222, which is connected to the unlock button recess 220.

[0056] Specifically, the latch plate 23 is placed on the latch plate groove 222. Based on the communication relationship between the latch plate groove 222 and the unlock button groove 220, the latch plate 23 is in partial contact with the unlock button 20.

[0057] Specifically, the middle area of ​​the latch plate 23 is provided with a latch hole 231, which cooperates with the latch 10 in the base self-locking structure 1. When the smart wearable device unlocking structure 2 and the base self-locking structure 1 self-lock, the latch block 102 of the latch 10 contacts the latch hole 231, and the contact surface between the latch block 102 and the latch hole 231 is inclined. When the latch hole 231 moves downward, the latch hole 231 applies an inward lateral force to the latch block 102, and pushes the latch block 102 towards the elastic member 11 based on the inclined surface, until the latch 10 passes through the latch hole 231. At this time, when the moving position of the latch hole 231 is below the latch block 102, the lateral force applied by the latch hole 231 to the latch block 102 disappears, and the latch block 102 is reset based on the force of the elastic member 11.

[0058] In one embodiment, the smart wearable device unlocking structure 2 further includes a screw 24.

[0059] Specifically, the latch plate 23 is provided with screw holes 230, the main unit 22 is provided with screw countersunk holes 223, and the unlock button 20 is provided with screw through holes 201.

[0060] Specifically, when the latch plate 23 is placed on the host 22, the screw hole 230, the screw through hole 201 and the screw countersunk hole 223 correspond to each other; the screw 24 head of the screw 24 passes through the screw hole 230 and the screw through hole 201 and is installed in the screw countersunk hole 223, and the screw 24 head of the screw 24 is located above the screw hole 230.

[0061] The following is an example of the unlocking structure 2 for the smart wearable device provided in this embodiment: The first end of the button spring 21 is placed into the button spring positioning hole 200, and then the second end of the button spring 21 is fitted onto the spring positioning post 221 of the unlocking button recess 220 provided on the host 22. At this time, the second end of the unlocking button 20 is exposed on the outer side of the host 22. Then, the latch plate 23 is placed on the latch plate recess 222 of the host 22 and partially contacts the unlocking button 20. The screw 24 is passed through the screw hole 230 of the latch plate 23 and the screw through hole 201 of the unlocking button 20 and screwed into the screw recess 223 on the host 22 to fix the unlocking button 20, thus realizing the unlocking structure 2 for the smart wearable device.

[0062] In one embodiment, the unlocking button 20 in the smart wearable device unlocking structure 2 is in contact with the locking tongue block 102 of the locking tongue 10 in the base self-locking structure 1.

[0063] In one embodiment, the locking tongue 10 in the base self-locking structure 1 includes a locked state and an unlocked state, such as... Figure 5 As shown, Figure 5 This is a structural diagram of the latch in the unlocked state provided in an embodiment of this application, wherein the structural diagram of the latch in the locked state is as follows. Figure 2 As shown.

[0064] In one embodiment, when the locking tongue 10 is in the locked state, the locking tongue 10 forms an movable gap with the locking tongue groove 11 under the force of the elastic member 11.

[0065] Specifically, the locking tongue block 102 forms an active gap with the locking tongue sliding limit plate 121 under the action of the elastic member 11.

[0066] In one embodiment, the base self-locking structure 1 is installed on the base of the smart wearable device, and the smart wearable device unlocking structure 2 is installed on the smart wearable device; based on the connection relationship between the base self-locking structure 1 and the smart wearable device unlocking structure 2, the smart wearable device base can lock and unlock the smart wearable device.

[0067] like Figure 6 As shown, Figure 6 A schematic diagram illustrating the installation process of the base self-locking structure and the smart wearable device unlocking structure provided in the embodiments of this application.

[0068] Example Description: Align the latch hole 231 of the latch plate 23 in the smart wearable device unlocking structure 2 with the latch 10 in the device groove 130 of the self-locking structure 1 of the base, and control the smart wearable device to move towards the base. At this time, the latch hole 231 on the latch plate 23 contacts the latch 10 and generates an inward force, causing the latch 10 to move inward against the outward force of the elastic element 11. At this time, the latch 10 is in the unlocked state. At the same time, the smart wearable device continues to move towards the base, and the latch 10 passes through the latch hole 231. The latch 10 loses the inward force exerted on it by the latch hole 231, and the elastic element 11 pushes the latch 10 outward again, so that the latch 10 is reset. At this time, the latch 10 is in the locked state and hooks the latch plate 23, restricting the six degrees of freedom of the smart wearable device. Thus, the quick installation of the smart wearable device and the base is completed.

[0069] In one embodiment, when the latch 10 is in the unlocked state, the unlock button 20 drives the latch 10 to deform the elastic element 11, and the latch 10 fits into the latch groove 11.

[0070] Specifically, when the unlock button 20 drives the latch 10, the latch 10 slides along the direction of the spring baffle 120. At this time, the elastic element 11 is in a deformed state. Under the action of the elastic element 11, the latch block 102 forms an active gap with the latch sliding limit plate 121. As the elastic element 11 is in a deformed state, the gap gradually narrows. The latch block 102 and the latch sliding limit plate 121 break through the action of the elastic element 11 and fit together.

[0071] like Figure 7 As shown, Figure 7 A schematic diagram illustrating the unlocking process of the base self-locking structure 1 and the smart wearable device unlocking structure provided in this application embodiment.

[0072] Example Description: Using the user's thumb and forefinger, apply an inward force to the unlocking buttons 20 on both sides of the unlocking structure 2 on the smart wearable device. This causes the unlocking buttons 20 to move inward against the outward elastic force of the button spring 21. The inward movement of the unlocking buttons 20 brings them into contact with the locking tongue 10 of the self-locking structure 1 on the base. The inward force of the unlocking buttons 20 is transmitted to the locking tongue 10, causing the locking tongue 10 to move inward against the outward elastic force of the elastic element 11 until the locking tongue 10 is in the unlocked state. The smart wearable device then moves in the opposite direction to the base, causing the locking tongue 10 on the base to disengage from the locking tongue hole 231 of the unlocking structure 2 on the smart wearable device. At this point, the inward force applied to the unlocking buttons 20 by the thumb and forefinger is released, completing the quick disassembly of the smart wearable device.

[0073] In one embodiment, the latch plate 23 and the latch 10 are made of a metal alloy material.

[0074] Specifically, due to the impact experienced by users in harsh environments, the greatest forces are exerted on the locking tongue plate 23 of the smart wearable device's unlocking structure 2 and the locking tongue 10 of the base's self-locking structure 1. Therefore, the locking tongue plate 23 of the smart wearable device and the locking tongue 10 of the base are made of high-strength metal alloy materials. This ensures that after the smart wearable device is installed and fixed, it will not loosen or be easily opened after being impacted in harsh environments. When users need to replace the battery or upload data, the smart wearable device can be easily removed from the base, achieving quick disassembly and replacement.
