[0043] Please refer to Figure 1-Figure 7 , Figure 1 and Figure 2 The structure of the smart watch in the embodiment of the present invention is shown. Figure 3-Figure 5 The structure of the meter body assembly in the embodiment of the present invention is shown. Figure 6 The structure of the ear in the embodiment of the present invention is shown. Figure 7 The structure of the connecting groove in the embodiment of the present invention is shown;

[0044] This embodiment provides a smart watch 100, which includes a main board (not shown in the figure), a display screen 110 and a watch body assembly 200;

[0045] The watch body assembly 200 includes a watch body 210 , a spring ear 201 and a watch band 230 ; the main board is installed in the watch body 210 ; the display screen 110 is connected to the front of the watch body 210 and is electrically connected to the main board.

[0046] The watch body 210 is provided with a connecting groove 211. The groove opening 212 of the connecting groove 211 includes a first section 213 located on the back of the watch body 210 and a second section 214 located on the side of the watch body 210. The first section 213 is connected to the second section 214. Ear holes 215 are provided on the groove walls at both ends of the connecting groove 211 along the extending direction of the connecting groove 211.

[0047] The spring ear 201 is connected to the watchband 230 , and one end of the watchband 230 connected to the spring ear 201 is accommodated in the connecting groove 211 , and the two heads 221 of the spring ear 201 are respectively matched with the two ear holes 215 , so that the watchband 230 is rotatably connected to the watch body 210 through the spring ear 201 .

[0048] It should be noted that when setting the connecting slot 211, the spring ear 201 and the strap 230, the smart watch 100 includes two straps 230 and two spring ears 201, and the connecting slots 211 are provided on the opposite sides of the watch body 210; wherein the connecting slots 211, the strap 230 and the spring ears 201 are connected one by one, and the connection method and principle are the same; therefore, in this embodiment, the connection of one of the connecting slots 211, the strap 230 and the spring ears 201 is taken as an example for description.

[0049] The working principle of the smart watch 100 is:

[0050] The mainboard of the smart watch 100 is installed in the watch body 210 and is electrically connected to the display screen 110. The display screen 110 is used to display various information output by the mainboard; the spring ear 201 is used to connect the watch body 210 and the watch band 230; wherein, in order to enable the spring ear 201 to be connected to the watch body 210, a connecting groove 211 is opened on the back of the watch body 210, and the notch 212 of the connecting groove 211 includes a first sub-portion 213 located on the back of the watch body 210 and a second sub-portion 214 located on the side of the watch body 210, and the first sub-portion 213 is connected to the second sub-portion 214; along the extension direction of the connecting groove 211, the groove walls at both ends of the connecting groove 211 are opened with ear holes 215;

[0051] When the watch band 230 is connected to the watch body 210 , since the spring ear 201 is connected to the watch band 230 , the two heads 221 of the spring ear 201 are respectively matched with the two ear holes 215 , so that the watch band 230 and the watch body 210 can be rotatably connected. In such a connection method between the watch strap 230 and the watch body 210, since the slot 212 for accommodating the connection slot 211 of the watch body 210 for accommodating the watch strap 230 and the ear 201 includes a first section 213 located on the back of the watch body 210 and a second section 214 located on the side of the watch body 210, when the watch strap 230 rotates relative to the watch body 210, it can rotate to the first section 213 and the second section 214 of the slot 212. As a result, the watch strap 230 can rotate to the back of the watch body 210 or to the side of the watch body 210, thereby increasing the rotation angle of the watch strap 230 relative to the watch body 210. In this way, the fit between the watch strap 230 and the user's wrist can be increased, thereby improving the wearing comfort. In addition, in this way, the bending or wear of the watch strap 230 due to the limited rotation angle during wearing can be reduced, thereby avoiding the breakage of the connection between the watch strap 230 and the watch body 210.

[0052] In addition, when the connecting groove 211 is opened on the watch body 210, since the notch 212 of the connecting groove 211 includes a first section 213 located on the back of the watch body 210 and a second section 214 located on the side of the watch body 210, such an opening method can reduce the space of the watch body 210 occupied by the connecting groove 211, thereby simplifying the watch body assembly 200, and further reducing the space of the watch body 210 occupied by the connecting groove 211 while increasing the internal space inside the watch body 210 for installing components of the smart watch 100.

[0053] For further information, please refer to Figure 1-Figure 7 In this embodiment, in order to reduce abnormal wear of the watch band 230 due to contact with the watch body 210 when the watch band 230 rotates relative to the watch body 210, or bending due to interference in movement, when the connecting groove 211 and the watch band 230 are provided, when the spring ear 201 is connected to the watch band 230, and the two heads 221 of the spring ear 201 are respectively matched with the two ear holes 215, so that the watch band 230 is rotatably connected to the watch body 210, the part of the watch band 230 accommodated in the connecting groove 211 is loosely matched with the connecting groove 211. In this way, the watch band 230 can be prevented from contacting the connecting groove 211, and the connecting groove 211 can be prevented from interfering with the rotation of the watch band 230 within the rotatable angle of the watch band 230.

[0054] It should be noted that, from the above content, it can be seen that since the slot 212 of the connecting slot 211 includes a first division 213 located on the back of the watch body 210 and a second division 214 located on the side of the watch body 210, and the back of the watch body 210 where the first division 213 is located is adjacent to the side of the watch body 210 where the second division 214 is located, when the strap 230 rotates relative to the watch body 210, it can rotate to the first division 213 and to the second division 214, and the angle between the two positions is the maximum angle of rotation of the strap 230 relative to the watch body 210.

[0055] For further information, please refer to Figure 1-Figure 8 , Figure 8 The structure of the first curved surface in the embodiment of the present invention is shown. In this embodiment, when the connection groove 211 and the watch band 230 are provided, the groove bottom surface of the connection groove 211 can be the first curved surface 216 and the reverse curved surface 217. The bending direction of the reverse curved surface 217 is opposite to the bending direction of the first curved surface 216. The first curved surface 216 is adapted to the end surface of the watch band 230, and the reverse curved surface 217 is connected to the first curved surface 216 and extends to the back of the watch body 210. Since the first curved surface 216 is adapted to the end surface of the watch band 230, when the watch band 230 rotates relative to the connection groove 211 of the watch body 210, the gap between the watch band 230 and the groove wall can be reduced by the clearance fit between the first curved surface and the end surface of the watch band 230, thereby ensuring the aesthetics.

[0056] When the reverse curved surface 217 is set, the first curved surface 216 and the end surface of the strap 230 are clearance-matched to ensure a large rotation angle of the strap 230, and the reverse curved surface 217 extends to the back of the watch body 210, and the back of the watch body 210 is used to fit the wrist of the user, so the aesthetics of the watch body 210 can be ensured by reducing the gap between the strap 230 and the bottom surface of the watch body 210, that is, when the reverse curved surface 217 is set, the curvature of the reverse curved surface 217 can be greater than or equal to the curvature of the first curved surface 216, thereby reducing the gap between the strap 230 and the bottom surface of the watch body 210.

[0057] Furthermore, in this embodiment, the end surface of the strap 230 accommodated in the connection groove 211 is a second arc surface 231; the first arc surface 216 is spaced from the second arc surface 231. With such a configuration, when the strap 230 rotates relative to the watch body 210, the second arc surface 231 located in the connection groove 211 can maintain a spaced state from the first arc surface 216, thereby avoiding contact between the strap 230 and the connection groove 211.

[0058] Specifically, in this embodiment, the central axis of the first curved surface 216 and the central axis of the second curved surface 231 can also be made to coincide with the central axis of the ear hole 215. In such a configuration, since the head 221 of the ear 201 cooperates with the ear hole 215, that is, the central axis of the ear hole 215 coincides with the axis of the ear 201, and since the axis of rotation of the strap 230 relative to the watch body 210 is the central axis of the ear 201, the central axis of the first curved surface 216 coincides with the axis of rotation of the strap 230 relative to the watch body 210, and since the first curved surface 216 is spaced from the second curved surface 231, that is, the radius of the first curved surface 216 is greater than the radius of the second curved surface 231, when the strap 230 rotates relative to the watch body 210 within its rotatable angle, it can maintain a state of being spaced from the groove wall of the connecting groove 211.

[0059] For further information, please refer to Figure 1-Figure 8In this embodiment, the ear 201 is a switch ear 220. By using the switch ear 220 to connect the watch strap 230 and the watch body 210, the connection steps of the watch strap 230 and the watch body 210 can be simplified. In addition, when the switch ear 220 is provided, in order to enable the switch ear 220 to be connected to the watch strap 230, a first mounting hole 232 and a second mounting hole 233 are provided at one end of the watch strap 230 connected to the watch body 210; wherein the first mounting hole 232 penetrates through both side surfaces of the watch strap 230, and the switch ear 220 is inserted into the first mounting hole 232, that is, the main body 222 of the switch ear 220 cooperates with the first mounting hole 232; the second mounting hole 233 is located on the end surface of the watch strap 230 and is connected to the first mounting hole 232, and the second mounting hole 233 accommodates the switch portion 223 of the switch ear 220. In other embodiments of the present invention, one end of the strap 230 connected to the watch body 210 may also be provided with a first mounting hole 232 and two second mounting holes 233; wherein the first mounting hole 232 passes through the two side surfaces of the strap 230, and the switch ear 220 is inserted into the first mounting hole 232; the two second mounting holes 233 are both located on the end surface of the strap 230 and are connected to the first mounting hole 232, and the two second mounting holes 233 respectively accommodate the two switch parts 223 of the switch ear 220.

[0060] For further information, please refer to Figure 1-Figure 8 In this embodiment, when the watch band 230 is rotatably connected to the watch body 210, the main body 222 of the switch ear 220 cooperates with the first mounting hole 232, the switch portion 223 of the switch ear 220 cooperates with the second mounting hole 233, and the head 221 of the switch ear 220 cooperates with the two ear holes 215 respectively. In order to prevent the switch portion 223 of the switch ear 220 from contacting the groove wall of the connecting groove 211 when the watch band 230 rotates relative to the watch body 210 and interfering with the rotation of the watch band 230 relative to the watch body 210, when the switch ear 220 is set, the height of the switch portion 223 of the switch ear 220 does not exceed the end surface of the watch band 230.

[0061] From the above content, it can be known that the central axis of the first curved surface 216 coincides with the axis of rotation of the strap 230 relative to the watch body 210, that is, the central axis of the first curved surface 216 coincides with the central axis of the ear 201. Since the short distance between any position of the switch portion 223 and the central axis of the ear 201 is smaller than the radius of the first curved surface 216, when the strap 230 rotates relative to the watch body 210 within its rotatable angle, the switch portion 223 can be kept spaced from the groove wall of the connecting groove 211, thereby preventing the switch portion 223 from interfering with the rotation of the strap 230 relative to the watch body 210.

[0062] The above are only specific embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
