[0009] Wherein, a partial structure of each male buckle can slide into the second slot section of the female slot along the first slot section of the female slot, and be limited between the bottom wall and the retaining edge of the second slot section of the female slot.

[0010] In one embodiment of the present invention, the male buckle comprises a rod portion and a cap portion, and a part of the structure of the cap portion protrudes from the outer peripheral wall of the rod portion; when the male buckle is connected to the female groove, each of the rod portions passes through a notch of the second groove section and extends into the second groove section, and the cap portion is limited between a retaining edge and a bottom wall of the second groove section;

[0011] And / or, the maximum width of the slot opening of the first slot section is greater than the maximum width of the slot opening of the second slot section.

[0012] In one embodiment of the present invention, an angle between an extension direction of one of the female grooves and an extension direction of at least another of the female grooves is greater than or equal to 90 degrees and less than or equal to 180 degrees.

[0013] In one embodiment of the present invention, the connection structure includes two connection components, the female grooves of the two connection components are arranged on the first connection part, and the male buckles of the two connection components are arranged on the second connection part.

[0014] In one embodiment of the present invention, the two male buckles are staggered, and the first groove sections of the two female grooves are staggered.

[0015] In one embodiment of the present invention, the male buckle and the second connecting portion are an integrally formed structure;

[0016] And / or, the material of the second connecting portion is a flexible material, and the material of the male buckle is a rigid material.

[0017] In one embodiment of the present invention, the first connecting portion has a first assembly surface, the second connecting portion has a second assembly surface, and the male buckle and the female groove are provided on the first assembly surface or the second assembly surface;

[0018] One of the first assembly surface and the second assembly surface is provided with a plurality of first protrusions, and when the male buckle is connected to the female groove, each of the first protrusions abuts against the other of the first assembly surface and the second assembly surface.

[0019] In one embodiment of the present invention, the other of the first assembly surface and the second assembly surface is provided with a plurality of limiting grooves;

[0020] When the male buckle is connected to the female groove, each of the first protrusions is accommodated and limited in one of the limiting grooves.

[0021] In one embodiment of the present invention, the other of the first assembly surface and the second assembly surface is provided with a plurality of second protrusions;

[0022] When the male buckle is connected to the female groove, the outer side wall of each of the first protrusions abuts against the outer side wall of a second protrusion to limit position.

[0023] In one embodiment of the present invention, one of the first assembly surface and the second assembly surface is provided with a surrounding block;

[0024] When the male buckle is connected to the female groove, the surrounding block is located at the periphery of each of the first protrusions and abuts against the other of the first assembly surface and the second assembly surface.

[0025] The technical solution of the present invention realizes the connection between the main body and the wristband in the wrist-worn device through at least two connecting components, wherein each connecting component includes a matching male buckle and a female groove, and the female groove includes a first groove section and a second groove section that are connected. When the wristband and the main body are assembled, a partial structure of each male buckle extends into the first groove section of a female groove, and enters the second groove section along the first groove section and is limited between the retaining edge and the bottom wall of the second groove section, so that each male buckle can be clamped and fixed with a female groove to realize the connection and fixation of the wristband and the main body. In the present invention, at least two female grooves have different extension directions, and the spacing between the first groove bodies of the two female grooves with different extension directions is different from the spacing between the second groove bodies. The two male buckles corresponding to the two female grooves that are clamped and matched need to first pass through the first groove sections of the two female grooves, and then slide into the second groove sections along the first groove sections of the two female grooves respectively, and cooperate with the corresponding retaining edge limit. In this process, because at least one of the first connection part and the second connection part is made of a flexible material, at least one of the first connection part and the second connection part can be twisted and deformed by the user when the user installs the wristband, so that the spacing between the two male buckles matched with the two female grooves can be changed, so that the partial structures of the two male buckles can be extended into the two first groove sections respectively, and then when the deformers in the first connection part and the second connection part are elastically restored, the two male buckles are reset and the spacing is changed again, so that the two male buckles can slide into the corresponding second groove sections respectively along the two first groove sections, so as to realize the snap-fitting of the above-mentioned two female grooves and the corresponding two male buckles. The extension directions of the above-mentioned two female grooves are different, which also determines that the sliding directions of the two male buckles when assembling or disassembling into the above-mentioned two female grooves are different, so that even if the wristband moves in a single direction due to accidental contact, the wristband will not slip off the main body, which can ensure the reliability of the wristband being installed and fixed on the main body. The connection structure between the wristband and the main body of the wrist-worn device provided by the present invention only includes at least two connection components, and each connection component only includes a matching male buckle and a female groove, which greatly simplifies the connection structure between the main body of the wrist-worn device and the wristband, and can effectively reduce the manufacturing cost of the wrist-worn device.

[0041] The present invention provides a wrist-worn device, which includes but is not limited to a smart watch or a wristband.

[0042] In one embodiment of the present invention, Figures 1 to 4As shown, the wrist-worn device includes a main body 1, a wristband 2 and a connection structure, the main body 1 has a first connection part 11; the wristband 2 has a second connection part 21, and the material of the first connection part 11 and / or the second connection part 21 is a flexible material; the connection structure includes at least two connection components, each connection component includes a matching male buckle 22 and a female groove 1a, one of the male buckle 22 and the female groove 1a of each connection component is arranged on the first connection part 11, and the other of the male buckle 22 and the female groove 1a of each connection component is arranged on the second connection part 21; each A female groove 1a has a first groove section 1a1 and a second groove section 1a2 that are connected, and the side wall of the second groove section 1a2 is provided with a retaining edge 111; the direction from the center of the first groove section 1a1 of each female groove 1a toward the center of the second groove section 1a2 is defined as the extension direction of the female groove 1a, and the extension directions of at least two female grooves 1a are different; wherein, a partial structure of each male buckle 22 can slide into the second groove section 1a2 of the female groove 1a along the first groove section 1a1 of a female groove 1a, and be limited between the bottom wall of the second groove section 1a2 of the female groove 1a and the retaining edge 111.

[0043] In this embodiment, combined with Figure 1 and Figure 2 As shown, the main body 1 is used for information display, such as the display of clock information; the wristband 2 is used to realize the main body 1 being worn and fixed on the human wrist; taking the wrist-worn device as a smart watch as an example, the main body 1 can be a dial, and the wristband 2 can be a watch strap. Among them, the main body 1 has two ends, and each end of the main body 1 is provided with a first connecting portion 11, and the first connecting portion 11 can be an integrally formed structure with the shell of the main body 1, and the material of the first connecting portion 11 can be the same as or different from the material of the shell of the main body 1, for example, the shell of the main body 1 can be a plastic material, and the material of the first connecting portion 11 is a silicone material; for another example, the material of the main body 1 and the material of the first connecting portion 11 are both plastic materials. The wristband 2 can be an integrated belt-like structure, in which case the two ends of the wristband 2 are respectively connected to the two ends of the main body 1 through a connecting structure, and the wristband 2 is put on the user's wrist to realize the wearing of the wrist-worn device; the wristband 2 can also include two independent belt-like structures respectively connected to the two ends of the main body 1 through the connecting structure, and the ends of the two independent belt-like structures away from the main body 1 are connected through a buckle structure to realize the wearing of the wrist-worn device. The wristband 2 has a second connecting part 21, and the second connecting part 21 can be made of the same material as the wristband 2, for example, the wristband 2 can be a silicone band with an integrated structure; or, the second connecting part 21 and the wristband 2 are made of different materials, for example, the wristband 2 is made of silicone and the second connecting part 21 is made of plastic, and the second connecting part 21 and the wristband 2 are integrally formed by a process such as two-color injection molding.

[0044] Further integration Figure 3 and Figure 4As shown, at least one of the first connection part 11 and the second connection part 21 is made of a flexible material, such as silicone, TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer rubber), etc. In this way, at least one of the first connection part 11 and the second connection part 21 can be deformed when under pressure, so that the spacing between the male buckles 22 or the spacing between the female grooves 1a can be correspondingly reduced or increased as the deformation occurs, so that the male buckle 22 can be engaged with or disengaged from the corresponding female groove 1a. Specifically, each female groove 1a in this embodiment includes a first groove segment 1a1 and a second groove segment 1a2 that are interconnected, and the direction from the center of the first groove segment 1a1 toward the center of the second groove segment 1a2 is defined as the extension direction of the female groove 1a (such as Figure 4 In the two female grooves 1a with different extension directions, the spacing between the first groove sections 1a1 and the second groove sections 1a2 are different. Therefore, when the two male buckles 22 matched with the two female grooves 1a slide into the second groove sections 1a2 of the two female grooves 1a through the first groove sections 1a1 of the two female grooves 1a, if the spacing between the two male buckles 22 remains unchanged, the spacing between the two female grooves 1a needs to be changed accordingly; if the spacing between the two female grooves 1a remains unchanged, the spacing between the two male buckles 22 needs to be changed accordingly. Because at least one of the first connecting section and the second connecting section is made of flexible material, the change in spacing between the two male buckles 22 can be achieved by setting the two male buckles 22 on the flexible material and then causing the flexible material to be deformed under pressure; the change in spacing between the two female grooves 1a can be achieved by setting the two female grooves 1a on the flexible material and then causing the flexible material to be deformed under pressure; the two male buckles 22 and the two female grooves 1a can also be connected or disconnected by setting one of the male buckles 22 and one of the female grooves 1a on the flexible material so that the spacing between the male buckle 22 and the female groove 1a on the flexible material changes when the flexible material is squeezed and deformed.

[0045] In practical applications, two female grooves 1a with different extension directions are simultaneously arranged on the first connection part 11, and two male buckles 22 cooperating with the two female grooves 1a are simultaneously arranged on the second connection part 21, and the material of the second connection part 21 is a flexible material. The spacing between the two male buckles 22 can be designed to be equal to the spacing between the second groove sections 1a2 of the two female grooves 1a. Because the extension directions of the two female grooves 1a are different, the spacing between the first groove sections 1a1 of the two female grooves 1a is not equal to the spacing between the second groove sections 1a2 of the two female grooves 1a. Here, the spacing between the second groove sections 1a2 of the two female grooves 1a is greater than the spacing between the first groove sections 1a1 of the two female grooves 1a. The spacing between the two male buckles 22 can be designed to be equal to the spacing between the two second slot sections 1a2. When the wristband 2 is assembled on the main body 1, the user squeezes and twists the second connection part 21 of the flexible material to deform the second connection part 21 and reduce the spacing between the two male buckles 22 on the second connection part 21. At this time, the partial structures of the two male buckles 22 can be respectively extended into the first slot sections 1a1 of the two female slots 1a. Afterwards, the user can remove the squeezing of the second connection part 21, so that the second connection part 21 of the flexible material can be elastically restored and drive the two male buckles 22 away from each other, and the distance between the two male buckles 22 gradually increases. The partial structures of the two male buckles 22 slide into the corresponding second slot sections 1a2 along the two first slot sections 1a1, and are respectively limited between the two retaining edges 111 and the bottom walls of the two second slot sections 1a2, so as to realize the clamping and fixing of the two buckles with the two female slots 1a. When removing the wristband 2 from the main body 1, the user squeezes and twists the second connecting part 21 of the flexible material again, so that the second connecting part 21 deforms and drives the two male buckles 22 to approach each other, and the distance between the two male buckles 22 gradually becomes smaller. The two male buckles 22 can slide into the corresponding first groove sections 1a1 along the two second groove sections 1a2 respectively, thereby realizing the separation of the two buckles from the two female grooves 1a.

[0046] In this embodiment, because at least two female grooves 1a extend in different directions, the male buckle 22 matched with the female grooves 1a with different extension directions has different sliding directions when being snap-fitted with or disassembled from the female grooves 1a. In this way, even if the wristband 2 moves in a single direction due to accidental contact, the wristband 2 will not slip off the main body 1, and the reliability of the installation and fixation of the wristband 2 on the main body 1 can be ensured. The connection structure of the wristband 2 and the main body 1 of the wrist-worn device provided by the present invention only includes at least two connection components, and each connection component only includes a matching male buckle 22 and a female groove 1a, which greatly simplifies the connection structure between the main body 1 of the wrist-worn device and the wristband 2, and can effectively reduce the manufacturing cost of the wrist-worn device.

[0047] In one embodiment of the present invention, Figure 5 and Figure 6As shown, the above-mentioned male buckle 22 includes a rod portion 221 and a cap portion 222, and part of the structure of the cap portion 222 protrudes from the outer peripheral wall of the rod portion 221; when the male buckle 22 is connected to the female groove 1a, each rod portion 221 passes through the notch of a second groove section 1a2 and extends into the second groove section 1a2, and the cap portion 222 is limited between a retaining edge 111 and a bottom wall of the second groove section 1a2; and / or, the maximum width of the notch of the first groove section 1a1 is greater than the maximum width of the notch of the second groove section 1a2.

[0048] In this embodiment, the rod 221 and the cap 222 of the male buckle 22 can be an integrally formed structure, and the material thereof can be the same material, such as plastic, silicone, etc. The rib 111 is arranged along the inner peripheral wall of the second groove section 1a2, and the rib 111 is a protruding structure on the side wall of the second groove section 1a2, and its extended shape can be a U-shape. When the wristband 2 is assembled with the main body 1, the cap 222 of the male buckle 22 extends into the first groove section 1a1 of the female groove 1a, the rod 221 slides along the first groove section 1a1 and slides into the second groove section 1a2 through the connection between the first groove section 1a1 and the second groove section 1a2, the rod 221 passes through the notch of the second groove section 1a2, the cap 222 is limited between the rib 111 and the bottom wall of the second groove section 1a2, and the male buckle 22 is engaged with the female groove 1a. The shape of the cap portion 222 may be square or circular, etc. The shape and size of the first slot segment 1a1 match those of the cap portion 222 so that the cap portion 222 can pass through the notch of the first slot segment 1a1 and extend into the first slot segment 1a1.

[0049] The inner peripheral wall of the first groove section 1a1 can be set in an arc surface, and the second groove section 1a2 can be a strip groove. Because the shape and size of the notch of the first groove section 1a1 match the shape and size of the cap portion 222, the notch area of ​​the first groove section 1a1 is smaller, and the hollow parts on the first connecting part 11 are less, which can ensure the structural strength of the first connecting part 11 and the reliability of the connection between the first connecting part 11 and the second connecting part 21. Therefore, when the maximum width of the notch of the first groove section 1a1 is greater than the maximum width of the notch of the second groove section 1a2, the notch area of ​​the second groove section 1a2 can be effectively reduced, thereby reducing the notch area of ​​the entire female groove 1a, so as to ensure the structural strength of the second connecting part 21 and the reliability of the connection between the first connecting part 11 and the second connecting part 21.

[0050] In one embodiment of the present invention, Figure 4 , Figure 6 as well as Figure 7 As shown, the angle between the extension direction of one of the above-mentioned female grooves 1a and the extension direction of at least another female groove 1a is greater than or equal to 90 degrees and less than or equal to 180 degrees.

[0051] In this embodiment, because at least two female grooves 1a extend in different directions, it is ensured that when the wristband 2 is disassembled from the main body 1, the male buckle 22 that is engaged with the female grooves 1a with different extending directions needs to slide in different directions to achieve the disassembly of the wristband 2 from the main body 1, so as to prevent the wristband 2 from easily slipping off the main body 1 when it is accidentally touched and slides in one direction. In addition, when the angle between the extending directions of the two female grooves 1a with different extending directions is greater than 0 degrees and less than 90 degrees, the sliding directions of the male buckle 22 that cooperates with the two female grooves 1a are more similar. For example, when the angle between the extending directions of the two female grooves 1a is 45 degrees, and the angle toward Figure 6 When the left direction is extended, the corresponding two male buckles 22 can be disengaged by sliding toward Figure 6 The left side sliding of the main body 1 shown in the figure is realized, then when the wristband 2 is accidentally touched relative to the main body 1 Figure 6 When the wristband 2 slides in the left direction as shown, it is still possible for the wristband 2 to slip off the main body 1. Therefore, the embodiment further sets the female grooves 1a with different extension directions, and there are two such female grooves 1a: the angle between the extension direction of one female groove 1a and the extension direction of the other female groove 1a is greater than or equal to 90 degrees and less than or equal to 180 degrees, so that the male buckle 22 engaged with the two female grooves 1a must be simultaneously oriented to the opposite sides of the main body 1 (for example, Figure 6 The left and right sides of the main body 1 as shown in the figure can be detached from the two female grooves 1a, and this irregular sliding will not occur during the normal wearing of the wrist-worn device, thereby further improving the reliability of the connection between the wristband 2 and the main body 1.

[0052] Alternatively, if Figure 6 As shown, the angle between the extension direction of one female groove 1a and the extension direction of the other female groove 1a is 90 degrees. At this time, the sliding disengagement direction of the male buckle 22 that is snap-fitted with the two female grooves 1a is also 90 degrees. During the normal wearing process of the wristband 2 device, the wristband 2 will not move in the horizontal and vertical directions relative to the main body 1 at the same time. Therefore, the structural setting of the above-mentioned female grooves 1a can ensure the reliability of the connection between the wristband 2 and the main body 1.

[0053] Alternatively, if Figure 7 As shown, the two female grooves 1a extend in the same direction, and the angle between the extension direction of one female groove 1a and the extension direction of the two female grooves 1a is 180 degrees. At this time, the sliding direction of the male buckle 22 that is snap-fitted with the two female grooves 1a that are 180 degrees to the extension direction is also 180 degrees. During normal wearing of the wristband 2 device, the wristband 2 will not move in two opposite directions relative to the main body 1 at the same time. Therefore, the structural setting of the above-mentioned female grooves 1a can ensure the reliability of the connection between the wristband 2 and the main body 1.

[0054] In one embodiment of the present invention, Figure 2 , Figure 3 as well as Figure 5 As shown, the connection structure includes two connection components, the female grooves 1a of the two connection components are arranged on the first connection part 11, and the male buckles 22 of the two connection components are arranged on the second connection part 21.

[0055] In this embodiment, only two female grooves 1a are provided on the first connection part 11, and the extension directions of the two female grooves 1a are different; two male buckles 22 are provided on the second connection part 21 accordingly, so that the number of female grooves 1a and the number of male buckles 22 can be reduced as much as possible on the basis of ensuring the connection reliability between the first connection part 11 and the second connection part 21, which is conducive to reducing the area of ​​the hollow part on the first connection part 11, ensuring the structural strength of the first connection part 11, and then ensuring the reliability of the connection between the first connection part 11 and the second connection part 21; at the same time, it can also reduce the material cost of the male buckle 22, thereby reducing the material cost of the wristband 2 device. In addition, because the two male buckles 22 are provided on the second connection part 21 of the wristband 2, it is also convenient for the user to hold the wristband 2 to install it on the main body 1, rather than holding the main body 1 to install it on the wristband 2, so that the main body 1 that is held and squeezed will not be the main body 1, which can protect the main body 1.

[0056] Optionally, the two male buckles 22 of the present embodiment are staggered, and the first groove sections 1a1 of the two female grooves 1a are staggered. When the male buckle 22 is engaged with the second groove section 1a2, the two male buckles 22 are respectively located in the two second groove sections 1a2, so that Figure 5 Taking the setting method of the male buckle 22 shown as an example, the two male buckles 22 are staggered in the vertical direction and the horizontal direction. In this way, even if the extension directions of the two female grooves 1a are different, the edge of the first connecting part 11 and the edge of the second connecting part 21 can still be aligned when the male buckle 22 is engaged with the second groove segment 1a2, avoiding the wristband 2 from being skewed when assembled with the main body 1, ensuring the aesthetics of the wristband 2 when assembled with the main body 1 and the good wearing experience of the wristband 2 device.

[0057] Optionally, the male buckle 22 and the second connecting portion 21 in this embodiment are an integrally formed structure; and / or, the material of the second connecting portion 21 is a flexible material, and the material of the male buckle 22 is a rigid material.

[0058] In this embodiment, when the male buckle 22 and the second connecting part 21 are made of the same material, such as silicone, the male buckle 22 and the second connecting part 21 can be integrally formed by an injection molding process; when the male buckle 22 and the second connecting part 21 are made of different materials, such as plastic and silicone, the male buckle 22 and the second connecting part 21 can be integrally formed by a two-color injection molding process. The integrally formed structure of the male buckle 22 and the second connecting part 21 can reduce the manufacturing process and cost of the wristband 2, and is conducive to improving the structural strength of the wristband 2, and ensuring the reliability of the wristband 2 when assembled with the main body 1.

[0059] When the material of the second connecting part 21 is a flexible material such as silicone or TPU, and the material of the male buckle 22 is a rigid material such as plastic or aluminum alloy, the second connecting part 21 is soft and can enhance the wearing experience of the user, and the male buckle 22 is rigid and can enhance the stability of the snap-fit ​​between the male buckle 22 and the female groove 1a, thereby enhancing the reliability of the assembly of the wristband 2 and the main body 1.

[0060] In one embodiment of the present invention, Figure 3 and Figure 5 As shown, the first connecting portion 11 has a first assembly surface 112, the second connecting portion 21 has a second assembly surface 211, the male buckle 22 and the female groove 1a are arranged on the first assembly surface 112 or the second assembly surface 211; one of the first assembly surface 112 and the second assembly surface 211 is provided with a plurality of first protrusions 113, and when the male buckle 22 is connected to the female groove 1a, each first protrusion 113 abuts against the other of the first assembly surface 112 and the second assembly surface 211.

[0061] In this embodiment, after the wristband 2 is assembled with the main body 1, when the wristband 2 slides relative to the main body 1, each first protrusion 113 plays a role in increasing friction resistance, hindering the relative sliding of the wristband 2 and the main body 1, thereby preventing the wristband 2 from loosening and reducing the risk of the wristband 2 slipping off the main body 1. In addition, because at least one of the first connecting portion 11 and the second connecting portion 21 is made of a flexible material, the cap 222 of the male buckle 22 will abut against the retaining edge 111 more closely under the spacer of the first protrusion 113, and the male buckle 22 is less likely to slide relative to the female groove 1a and disengage, which can improve the reliability of the assembly of the wristband 2 and the main body 1. Among them, the material of the first protrusion 113 can be silicone, rubber, etc., and its surface can be treated by frosting or other treatments to increase friction resistance.

[0062] Optionally, the other of the first assembly surface 112 and the second assembly surface 211 is provided with a plurality of limiting grooves; when the male buckle 22 is connected to the female groove 1a, each first protrusion 113 is accommodated and limited in a limiting groove. Through the limiting cooperation between the limiting groove and the first protrusion 113, on the one hand, the gap between the first assembly surface 112 and the second assembly surface 211 caused by the spacer of the first protrusion 113 can be reduced or eliminated, so that the wristband 2 and the main body 1 can be seamlessly assembled, and the aesthetics and wearing experience of the wristband 2 device can be improved; on the other hand, the inner peripheral wall of the limiting groove can better stop the movement of the first protrusion 113, so that the first connecting part 11 is difficult to slide relative to the second connecting part 21, so that the wristband 2 is less likely to slide relative to the main body 1 and disengage, which can improve the reliability of the assembly of the wristband 2 and the main body 1.

[0063] Optionally, the other of the first assembly surface 112 and the second assembly surface 211 is provided with a plurality of second protrusions 212; when the male buckle 22 is connected to the female groove 1a, the outer wall of each first protrusion 113 abuts against the outer wall of a second protrusion 212 for limiting position. In this way, under the mutual stop limit of the first protrusion 113 and the second protrusion 212, the first connection part 11 can be effectively prevented from sliding relative to the second connection part 21, making it less likely for the wristband 2 to slide relative to the main body 1 and detach, thereby improving the reliability of the assembly of the wristband 2 and the main body 1.

[0064] Optionally, one of the first assembly surface 112 and the second assembly surface 211 is provided with a block 114; when the male buckle 22 is connected to the female groove 1a, the block 114 is located at the periphery of each first protrusion 113 and abuts against the other of the first assembly surface 112 and the second assembly surface 211. The block 114 can be arranged along the edge of the first assembly surface 112 or the second assembly surface 211, so that the block 114 will block the gap between the first connection part 11 and the second connection part 21 due to the first protrusion 113 spacer, and make the first protrusion 113 invisible to the user, realize the hidden design of the first protrusion 113 and the seamless connection design of the wristband 2 and the main body 1, and improve the aesthetics and wearing experience of the wristband 2 device. Among them, the shape of the block 114 can be square, ring, etc., and the material of the block 114 can be silicone, rubber and elastic material, and its thickness can be greater than the thickness of the first protrusion 113, so that the block 114 can block each first protrusion 113 when the wristband 2 is connected to the main body 1.
