Description

Technical Field

[0001] This application relates to the technical field of smart wearable devices, and in particular to a wearable device. Background Technology

[0002] With the development of internet technology and intelligent products, various intelligent wearable products have appeared on the market. Among them, smartwatches, as a common type of intelligent wearable product, have brought convenience to users.

[0003] The use of a detachable strap to connect to the watch body has become the mainstream solution for watches and fitness trackers in recent years. However, the current detachable strap design takes up a significant amount of internal space in the watch case, leading to space constraints for these wearable products. Summary of the Invention

[0004] This application provides a wearable device to solve the technical problem that detachable watch straps take up too much space inside the watch body.

[0005] In a first embodiment of this application, a wearable device is provided, comprising a watch strap and a watch body. The watch body includes a housing and buttons. The watch strap includes a buckle. The housing includes an end frame and a side frame, the end frame and the side frame forming a receiving cavity. The end frame includes a sub-side surface and a mounting groove recessed into the end frame from the sub-side surface. The mounting groove includes a first groove sidewall and a second groove sidewall. Along the thickness direction of the end frame, the first groove sidewall and the second groove sidewall are spaced apart and opposite to each other, with the second groove sidewall close to the receiving cavity. The button includes a pressing body and a button body. The button body protrudes from the surface of the pressing body, and the width of the pressing body is greater than the width of the button body. The button is accommodated and confined in the mounting groove, wherein the button body extends into the mounting groove and is located between the sidewall of the first groove and the sidewall of the second groove. In the thickness direction of the housing, part of the pressing body is opposite to the sidewall of the second groove, and the orthographic projection of the pressing body in the thickness direction of the housing overlaps with the orthographic projection of the sidewall of the second groove in the thickness direction of the housing. The latching part passes through the side wall of the first groove, and the button can move relative to the mounting groove along the thickness direction of the housing. The latching part can engage or unlock the button.

[0006] In this embodiment, the width of the pressing body is greater than the thickness of the button body. This avoids the button body occupying too much space in the housing. In the thickness direction of the watch body, the pressing body overlaps with the limiting strip, meaning the pressing body overlaps with the second groove sidewall on the housing in the thickness direction. This reduces the width space occupied by the button while ensuring a wider button appearance, meaning the pressing body has sufficient area for pressing contact. The thickness of the housing is reduced compared to the width of the pressing body, avoiding occupying space in the length direction (Y-axis) of the housing (the thickness of the end frame can be reduced). The space created by the thickness difference between the pressing body and the housing allows for a reduction in the thickness of the end frame. This reduces the thickness of the end frame, thereby increasing the Y-axis dimension of the housing's mounting cavity, increasing housing capacity, and providing sufficient space for battery volume, antenna clearance, etc. It also provides interconnection area for the connection between the watch strap and the watch body, ensuring the capacity of the watch body while enhancing the connection stability between the watch strap and the watch body.

[0007] In one embodiment, the second groove sidewall is provided with a connecting end face, the connecting end face facing the thickness direction of the housing, and the watch body further includes a back cover, the back cover including a limiting strip. The back cover is mounted on one side of the housing and connected to the end frame and the side frame. The limiting strip is fixed to the connecting end face by an adhesive connection. Along the thickness direction of the housing, the limiting strip partially overlaps with the pressing body. In this embodiment, the back cover, housing, and button have overlapping portions in the thickness direction perpendicular to the watch body, which can reduce the thickness of the end frame and increase the capacity of the mounting cavity.

[0008] In one embodiment, a support platform is protruding from the connecting end face, and the support platform is located on the side of the second groove sidewall away from the receiving cavity; the support platform is located between the limiting strip and the button body, and along the thickness direction of the housing, the limiting strip and the support platform overlap with the pressing body. The support platform in this embodiment can improve the installation stability of the back cover, housing, and button. In one embodiment, the end frame includes a sub-side surface, an outer end surface, and an inner end surface disposed opposite to the outer end surface. The sub-side surface connects the outer end surface and the inner end surface, and the mounting groove is disposed on the sub-side surface. The outer end face is provided with a recess, the recess includes a bottom wall, and the peripheral edge of the bottom wall has a concave surface along the thickness direction of the end frame; The watch strap includes an end portion, which comprises a first sub-end portion and a second sub-end portion located around the periphery of the first sub-end portion. The second sub-end portion protrudes from the first sub-end portion and is inclined toward the first sub-end portion. The buckle portion protrudes from the first sub-end portion. The end portion is inserted into the recess, and the second sub-end portion is opposite to the recessed surface.

[0009] In this embodiment, the end of the watch strap is not planar; that is, the second sub-end has a beveled surface, and the concave surface is an inclined surface. The fit between the second sub-end and the concave surface allows the edge of the watch strap to insert deeper into the case, resulting in a tighter fit between the end and the case. When the watch strap is pulled by external force, the second sub-end has enough slack to move away from the case without creating gaps, thus avoiding affecting the external aesthetics of the watch. Conversely, if the end is planar, and the mating position with the case is also planar, there would be insufficient slack between the end and the case when the watch strap is pulled by external force, potentially creating gaps that affect the appearance.

[0010] In one embodiment, the rear shell has a notch at its end, and the limiting strip protrudes into the notch. The notch faces the sidewall of the first groove and forms a gap with the sidewall of the first groove. The pressing body closes the gap between the notch and the sidewall of the first groove. The pressing surface of the pressing body protrudes from the rear shell.

[0011] In this embodiment, the back cover and the first groove sidewall of the mounting groove limit the button perpendicular to the thickness direction, eliminating the need for additional structures, simplifying the design of the watch body, and saving space.

[0012] In one embodiment, the button further includes a limiting block, and the button body is also provided with a limiting groove. Along the thickness direction of the button, the limiting groove passes through the button body, and the limiting block passes through the limiting groove. The limiting hole is provided on the wall surface of the first groove sidewall facing the second groove sidewall and the wall surface of the second groove sidewall facing the first groove sidewall. The limiting block protrudes from the opposite ends of the limiting groove and is inserted into the two limiting holes respectively.

[0013] In this embodiment, limiting holes are provided on the first and second groove sidewalls, and limiting grooves are provided on the button to cooperate with limiting blocks. The limiting blocks limit the button between the first and second groove sidewalls of the mounting groove and provide a certain stroke for the button to slide. Its structure is simple and does not occupy additional thickness space of the end frame.

[0014] In one embodiment, the end frame further includes two retaining holes and two receiving grooves. The two retaining holes penetrate the side wall of the first groove and the recess. The limiting hole is located between the two retaining holes. The two receiving grooves are recessed in the side wall of the second groove and face the side wall of the first groove. The two buckle portions pass through the two retaining holes and the button respectively and are limited in the receiving grooves. The buckle portion includes a hook portion, and the hook portion has an inclined surface.

[0015] In this embodiment, the bottom wall of the receiving groove is an inclined surface, and the inclined surface of the hook portion mates with the inclined surface of the receiving groove. In other embodiments, the bottom wall of the receiving groove is a plane, which can be understood as the cross-section of the receiving groove being rectangular.

[0016] In this embodiment, a latching part with a hook is used to hold the button, and a receiving groove is provided on the side wall of the second groove to accommodate the protruding part of the button (hook) of the latching part. This reduces the thickness of the end frame occupied by the latching part, facilitating the thinning design of the end frame. Moreover, the hook has a bevel, which makes it easier for the hook to pass through the latching hole and engage with the latching body. The bevel of the hook matches the beveled bottom wall of the receiving groove, which is beneficial to the cavity of the end frame.

[0017] In one embodiment, the button further includes an elastic body, and a guide post is provided at the end of the button body facing away from the pressing body. The elastic body is sleeved on the guide post and elastically abuts against the bottom wall of the mounting groove. In this embodiment, the elastic body is a helical spring, which is used to provide a restoring force for the button.

[0018] In one embodiment, the width of the pressing body is greater than or equal to 1 mm and less than or equal to 3 mm, the thickness of the button body is greater than or equal to 0.4 mm and less than or equal to 1.5 mm, and the thickness of the end frame is less than or equal to 3.2 mm. The end frame thickness in this embodiment is even smaller.

[0019] In one embodiment, the pressing body includes a first part and a second part. The first part and the second part are connected along the width direction of the pressing body. The button body protrudes from the first part. Along the thickness direction of the end frame, the width of the pressing body is greater than the thickness of the button body, and the width of the first part is greater than or equal to the thickness of the button body.

[0020] In one embodiment, the button has an L-shaped cross-section or a T-shaped cross-section. Along the thickness direction of the housing, and relative to the bottom wall of the mounting groove, the height of the first groove sidewall is higher than the height of the second groove sidewall, and the second portion of the button's pressing body is opposite to the second groove sidewall.

[0021] In this embodiment, the width of the button's pressing body is greater than the thickness of the main body. While ensuring the pressing area, the thickness space occupied by the main body in the end frame can be reduced, thereby achieving a smaller size compared to the prior art.

[0022] In one embodiment, along the thickness direction of the housing, the groove sidewall of the mounting groove extends at an angle relative to the thickness direction of the watch body, and the button body is also at an angle relative to the thickness direction of the watch body.

[0023] In this embodiment, the button body is tilted, and the corresponding mounting slot is tilted. While ensuring the depth of the mounting slot, the height dimension of the occupied end frame can be reduced, which means the thickness dimension of the shell is reduced, making it more conducive to the thinner design of the watch body.

[0024] In one embodiment, the angle of inclination of the mounting groove and the button body relative to the thickness direction of the watch body, wherein the angle of the button body is greater than or equal to 2 degrees and less than or equal to 20 degrees.

[0025] In this embodiment, the button body is connected to the mounting surface of the pressing body and is inclined relative to the mounting surface. The pressing surface of the button is an arc-shaped surface. The connection between the outer end face of the end frame and the sub-side face of the end frame is an arc-shaped surface. The watch body also includes a back case. The outer surface of the back case is an arc-shaped surface on the side near the frame. The outer end face, the sub-side face, the pressing surface, and the outer surface of the back case are sequentially connected to form the arc-shaped outer contour surface of the watch body.

[0026] In one embodiment, the button body includes a surface facing away from the body along the thickness direction and two parallel end faces. One end face faces away from the pressing body, and the other end face is connected to the pressing body. The two surfaces are parallel to each other, and the two surfaces connect the two end faces and are set at an angle to the end faces. The surfaces are connected at an angle to the mounting surface of the pressing body. The angle is not a right angle, but it can be a right angle.

[0027] In one embodiment, the first groove sidewall and the second groove sidewall are parallel to each other and form an angle with the bottom wall of the mounting groove, and the two surfaces are parallel to and opposite to the first groove sidewall and the second groove sidewall. In a second embodiment of this application, a wearable device is provided, including a watch strap and a watch body. The watch body includes a housing, a back cover, and buttons. The watch strap includes a buckle. The housing includes an end frame. The end of the back cover has two abutting portions. The end frame includes a sub-side and a mounting groove recessed into the end frame from the sub-side. The mounting groove includes two groove end walls, which are spaced apart and opposite to each other along the length of the end frame. Each groove end wall has a limiting step facing the opening of the mounting groove. The button includes a pressing body and a button body. The button body protrudes from the pressing body. Along the thickness direction of the end frame, the width of the pressing body is greater than or equal to the thickness of the button body. The button further includes a first retaining body, which is disposed at opposite ends of the pressing body along its length and on opposite sides of the button body. The first retaining body extends away from the pressing body and bends away from the button body. The button is accommodated in the mounting groove, and the button body extends into the mounting groove. The back cover covers one side of the housing, and the pressing body protrudes from the back cover. Along the thickness direction of the watch body, the abutting portion is respectively spaced opposite to the two limiting steps. The first retaining body is limited between the abutting portion and the limiting step, and the abutting portion abuts against the first retaining body. The latching part is inserted into the mounting groove from the outside of the end frame. The button can move relative to the mounting groove along the thickness direction of the housing. The first holding body moves relative to the limiting platform. The latching part can engage or unlock the button.

[0028] In this embodiment, the first retaining body cooperates with the stepped surface to limit the button's position in the thickness direction of the watch body, preventing the button 40 from detaching from the mounting slot. This eliminates the need for a limiting groove (extending along the width direction of the body) and a limiting block (as in the first embodiment) on the button body to limit its position in the thickness direction. This further reduces the width of the body (the thickness of the watch body), i.e., reduces the width of the button, and correspondingly reduces the depth of the mounting slot, further reducing the thickness dimension of the casing, and thus reducing the overall thickness of the watch body, facilitating a thinner watch design. Furthermore, the elimination of the limiting groove improves the button's strength. The removal of the limiting block also eliminates the need for limiting holes on the casing, reducing the thickness of the end frame and providing more space for the receiving cavity, further enhancing the end frame's strength. In summary, the cooperation between the button and the back-case mounting slot in this embodiment saves internal space in the Y-axis direction and also saves space in the thickness direction (Z-axis) of the casing, thus facilitating a thinner watch design or a more multifunctional watch design.

[0029] In one embodiment, the mounting groove includes a first groove sidewall and a second groove sidewall. Along the thickness direction of the end frame, the first groove sidewall and the second groove sidewall are spaced apart and opposite to each other. The two groove endwalls are spaced apart and opposite to each other along the length direction of the end frame. The two groove endwalls connect the first groove sidewall and the second groove sidewall. The button body is located between the first groove sidewall and the second groove sidewall. The end frame also includes a retaining hole that penetrates the side wall of the first groove, and the latching part passes through the retaining hole to retain the button body in the thickness direction. In this embodiment, the end face of the button body facing away from the pressing body is completely offset from and flush with the wall of the retaining hole facing the pressing body, or, in the direction from the bottom wall of the mounting groove to the opening of the mounting groove, the end face is lower than the wall of the hole. In this embodiment, the latching part passes through the retaining hole and is held by the second retaining body of the button, while the button is limited in the thickness direction of the shell by the limiting step in the mounting groove, without the need for the side wall of the mounting groove to limit it. In the thickness direction of the shell, the button does not need to exceed the wall of the retaining hole, which can reduce the width of the button and thus reduce the thickness of the shell.

[0030] In one embodiment, a receiving groove is provided on the side wall of the second groove, the receiving groove being recessed into the side wall of the second groove and facing the side wall of the first groove. The latching part passes through the retaining hole and the button and is confined within the receiving groove. The latching part includes a hook with a beveled surface. The beveled surface of the hook facilitates the latching part passing through the retaining hole, reduces friction with the retaining hole, and also facilitates latching with the second retaining body.

[0031] In one embodiment, the rear shell is further provided with a notch, the notch is provided on the end face of the rear shell, the abutting part is located on opposite sides of the notch, the notch is provided with an abutting platform, and the notch has a mating surface connected to the abutting platform; A limiting strip is protruding from the end face of the side wall of the second groove; The back cover is mounted on one side of the housing, the pressing body is located at the notch, along the length of the watch body, the side of the pressing body is opposite to the mating surface, and along the thickness of the watch body, the abutment is opposite to the limiting strip of the second groove sidewall. In one embodiment, the end frame includes a sub-side surface, an outer end surface, and an inner end surface disposed opposite to the outer end surface. The sub-side surface connects the outer end surface and the inner end surface, and the mounting groove is disposed on the sub-side surface. The outer end face is provided with a recess, the recess includes a bottom wall, and the peripheral edge of the bottom wall has a concave surface along the thickness direction of the end frame; The watch strap includes an end portion, which includes a first sub-end portion and a second sub-end portion located around the periphery of the first sub-end portion. The second sub-end portion protrudes from the first sub-end portion, and the clasp portion protrudes from the first sub-end portion. The end portion is inserted into the recess, and the second sub-end portion faces the concave surface. In this embodiment, the end of the watch strap is not planar; that is, the second sub-end portion has a beveled surface, and the concave surface is an inclined surface. The fit between the second sub-end portion and the concave surface allows the edge of the watch strap to insert deeper into the housing, resulting in a tighter fit between the end and the housing. When the watch strap is pulled by external force, the second sub-end portion has sufficient slack to move away from the housing without creating gaps, thus avoiding affecting the external aesthetics of the watch. Conversely, if the end portion is planar, and the mating position with the housing is also planar, there would be insufficient slack between the end portion and the housing when the watch strap is pulled by external force, potentially creating gaps that affect the appearance.

[0032] In one embodiment, the width of the pressing body is greater than or equal to 1 mm and less than or equal to 3 mm, the thickness of the button body is greater than or equal to 0.4 mm and less than or equal to 1.5 mm, the width of the button 40 is greater than or equal to 2.3 mm and less than or equal to 4 mm, and the thickness of the shell is greater than or equal to 4 mm. In this embodiment, the travel of the button is limited by the limiting steps of the back shell and the mounting groove, which can save the width of the button and reduce the depth occupied by the mounting groove, that is, save the thickness of the shell and achieve the purpose of shell thinning.

[0033] In one embodiment, the button further includes an elastic body, and a guide post is provided at the end of the button body facing away from the pressing body. The elastic body is sleeved on the guide post and elastically abuts against the bottom wall of the mounting groove. In this embodiment, the elastic body is a helical spring, which is used to provide a restoring force for the button.

[0034] In one embodiment, the button has an L-shaped cross-section or a T-shaped cross-section. The width of the pressing body is greater than the thickness of the main body, which, while ensuring the pressing area, reduces the thickness space occupied by the main body in the end frame, thereby achieving a smaller size compared to the prior art.

[0035] In one embodiment, the pressing body includes a first part and a second part. The first part and the second part are connected along the width direction of the pressing body. The button body protrudes from the first part. Along the thickness direction of the end frame, the width of the pressing body is greater than the thickness of the button body, and the width of the first part is greater than or equal to the thickness of the button body.

[0036] In the wearable device of this application, the button adopts a design with different thicknesses of the pressing body and the main body, so that the button overlaps with the shell and the back shell in the direction perpendicular to the thickness. This can reduce the thickness of the frame, thereby increasing the size of the mounting cavity of the shell, increasing the shell capacity, and providing sufficient space for the battery volume, antenna clearance size, etc. Attached Figure Description

[0046] Please see Figure 4 and Figure 5 , Figure 4 for Figure 2 The diagram shows an exploded view of the watch body and part of the watch strap. Figure 5 for Figure 4 The diagram shows an exploded view of the watch body and part of the strap from another angle. For ease of description, the width direction of the watch body 100 is defined as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. The X, Y, and Z axes are mutually perpendicular. The Y-axis represents the length of the case 10, the Z-axis represents the thickness of the case, and the X-axis represents the width of the case 10.

[0047] In this embodiment, the watch body 100 has a rectangular structure, with the back cover 20 and the display screen 30 mounted on opposite sides of the thickness direction of the body 10. A button 40 is mounted on the body 10 and protrudes from the back cover 20. The button 40 moves towards the body 10 to unlock the watch strap 200. For ease of description, the following description uses only one watch strap 200 connected to the watch body 100 as an example, and all connection structures described only relate to one watch strap, such as one button. In reality, two buttons 40 are provided at both ends of the watch body 100 along its length direction for connecting to two watch straps 200.

[0048] The display screen is a rectangular flat panel. The back cover 20 is a rectangular plate, including an outer surface 21, an inner surface 22, and an end face 23. The outer surface 21 and the inner surface 22 are arranged opposite to each other along the thickness direction of the back cover 20, and the end face 23 connects the outer surface 21 and the inner surface 22. The end of the back cover 20 is provided with a notch 24, which is recessed from the end face 23 into the back cover 20 and penetrates the outer surface 21 and the inner surface 22. The back cover 20 also includes a limiting strip 25, which protrudes into the notch 24 and extends toward the end face 23. The limiting strip 25 is used to limit the button 40. In this embodiment, the limiting strip 25 includes a first surface 251 and a second surface 252, which are arranged opposite to each other along the thickness direction of the back cover 20. The first surface 251 faces the same direction as the inner surface 22, and the second surface 252 faces the same direction as the outer surface 21. Both the first surface 251 and the inner surface 22 are used to connect with the housing 10.

[0049] See also Figure 4 and Figure 6 , Figure 6 for Figure 4 The diagram shows a partial planar schematic of the watch strap. The watch strap 200 includes a strap body 210 and a buckle portion 220, with the buckle portion 220 protruding from the end face of the strap body 210. In this embodiment, the strap body 210 includes an end portion 230, which includes a first sub-end portion 230a and a second sub-end portion 230b located around the periphery of the first sub-end portion 230a. The second sub-end portion 230b protrudes from the first sub-end portion 230a and is inclined toward the first sub-end portion 230a. The buckle portion 220 protrudes from the surface of the first sub-end portion 230a. The buckle portion 220 consists of two hooks, each including a main body (not shown) and a hook portion 222, which protrudes from the end of the main body away from the strap body 210. The materials of the strap body 210 and the buckle portion 220 can be the same or different, and the materials of the strap body 210 and the buckle portion 220 are not limited; the strap body 210 can be made of fiber, plastic, or metal. The buckle 220 can be made of plastic or metal. For example, if the belt body 210 is made of rubber, the buckle 220 can be made of elastic metal and is embedded in the belt body 210. The belt body 210 can also be made of woven material.

[0050] In this embodiment, the housing 10 is a rectangular frame structure, including two oppositely arranged side frames 11, two oppositely arranged end frames 12, a first side surface 13, and a second side surface 14. The two side frames 11 are respectively connected to the two end frames 12 to form a mounting cavity 101 for accommodating watch components such as the battery circuit board. The first side surface 13 and the second side surface 14 are arranged opposite to each other along the thickness direction of the housing 10. The first side surface 13 is formed by the side frames 11 and the end frames 12 facing the same direction, and the second side surface 14 is formed by the other side of the side frames 11 and the end frames 12. The second side surface 14 has a step 141 recessed into the mounting cavity 101, which is used to support the display screen 30. The length direction of the housing 10 is the thickness direction of the end frames 12, the thickness direction of the housing 10 is the height direction of the end frames 12, and the width direction of the housing 10 is the length direction of the end frames 12.

[0051] Please refer to the following: Figure 7 and Figure 8 , Figure 7 for Figure 4 The diagram shows the structural schematic of the shell. Figure 8 for Figure 7 The shown is a cross-sectional view of the shell structure.

[0052] The end frame 12 includes a sub-side surface 121, an outer end surface 122, and an inner end surface 123. The outer end surface 122 and the inner end surface 123 are arranged opposite to each other along the thickness direction of the end frame 12, and the sub-side surface 121 connects the outer end surface 122 and the inner end surface 123. The sub-side surface 121 is part of the first side surface 13. The end frame 12 also includes a recess 124, which is formed by the outer end surface 122 recessed towards the inner end surface 123. The recess 124 includes a bottom wall 1241 and two side walls 1242, which are connected to opposite sides of the bottom wall 1241. Along the thickness square of the housing 10, that is, the width direction of the recess 124, the peripheral edge of the bottom wall 1241 has a concave surface 1243, which surrounds the bottom wall 1241 and is inclined towards the first side surface 13 and the second side surface 14. The end 230 of the watch strap 200 is inserted into the recess 124, and the second sub-end 230b is opposite to the concave surface 1243, so that the edge of the watch strap 200 is inserted deeper into the housing 10. Compared with the fit of two planes, this avoids gaps between the edge of the watch strap 200 and the housing 10 when the watch strap 200 is pulled by external force, which would affect the external appearance of the watch.

[0053] The end frame 12 also includes a mounting groove 15, a retaining hole 16, a limiting hole 17, and a receiving groove 18. In this embodiment, there are two retaining holes 16, two limiting holes 17, and two receiving grooves 18. Other structures that cooperate with the retaining holes 16, two limiting holes 17, and two receiving grooves 18 will be used as examples in the following descriptions. In other embodiments, the number of retaining holes 16, two limiting holes 17, and two receiving grooves 18 can be one or more, depending on actual usage requirements, and is not specifically limited. The mounting groove 15 is used to mount the button 40. It is recessed from the sub-side 121 into the end frame 12, and the opening of the mounting groove 15 (not shown in the figure) is located on the sub-side 121. In this embodiment, the mounting groove 15 is a rectangular groove that extends along the length of the end frame 12. The mounting groove 15 includes a bottom wall (not shown in the figure) and a first groove side wall 151 and a second groove side wall 152 protruding from the bottom wall. Along the thickness direction of the end frame 12 (the length direction of the housing 10), the first groove side wall 151 and the second groove side wall 152 are spaced apart and opposite each other. The side of the first groove side wall 151 facing away from the mounting groove 15 is the bottom wall 1241 of the recess 124. Two retaining holes 16 and a limiting hole 17 are both formed on the first groove side wall 151 and penetrate the first groove side wall 151 along the thickness direction of the end frame 12, that is, they penetrate the bottom wall 1241 of the recess 124. The limiting hole 17 is located between the two retaining holes 16. In this embodiment, both retaining holes 16 and the limiting hole 17 are rectangular through holes. In other embodiments, the shape of the holes is not limited, as long as they can fit with the watch strap 200.

[0054] Both receiving grooves 18 are recessed on the surface of the second groove sidewall 152 facing the first groove sidewall 151, and each of the two receiving grooves 18 corresponds to one of the two retaining holes 16. The buckle portion 220 of the watch strap 200 can be inserted into the mounting groove 15 through the two retaining holes 16, and the hook portion 222 can be accommodated in the receiving groove 18 after being engaged with the button 40. In this embodiment, two of the three receiving grooves 18 are used to cooperate with the hook portion 222. The end of the hook portion 222 facing the receiving groove 18 is beveled, and the beveled surface of the hook portion 222 facilitates insertion into the retaining hole and engagement with the retaining body. In one embodiment, the bottom wall of the receiving groove 18 facing the hook portion 222 is beveled, which can improve the strength of the end frame. After the hook portion 222 extends into the receiving groove 18, the beveled surface of the hook portion 222 is opposite to the beveled surface of the receiving groove 18. Furthermore, by providing a receiving groove 18 on the second groove sidewall 152 to accommodate the protruding button 40 (hook) of the latching part 220, the thickness of the end frame 12 occupied by the latching part 220 can be reduced, which facilitates the thinning design of the end frame 12.

[0055] Along the width direction of the end frame 12 (thickness direction of the housing 10), the height of the first groove sidewall 151 is higher than the height of the second groove sidewall 152 compared to the sub-side surface 121. The second groove sidewall 152 has a connecting end face 1521 and a support platform 1522. The orientation of the connecting end face 1521 is the same as the orientation of the sub-side surface 121, and the support platform 1522 protrudes from the connecting end face 1521 on the side near the first groove sidewall 151. When the rear shell 20 is installed in the housing 10, the first surface 251 of the limiting strip 25 faces the connecting end face 1521 and is connected by an adhesive layer (not shown). It can be understood that the second groove sidewall 152 is a mounting wall that mates with the rear shell 20. In other embodiments, the support platform 1522 may be omitted, and the connecting end face 1521 is an end face that is planar over the entire second groove sidewall 152.

[0056] Please see Figure 5 and Figure 9 , Figure 9 for Figure 4The diagram shows the structure of the button. The button 40 includes a pressing body 41, a button body 42, an elastic body 43, and a limiting block 44. The elastic body 43 is a helical spring. The pressing body 41 includes a mounting surface 411, a pressing surface 412, and two opposing side surfaces 413. The mounting surface 411 and the pressing surface 412 are arranged back to back, and the side surfaces connect the mounting surface 411 and the pressing surface 412. The pressing surface 412 is used to expose the housing 10 to realize the pressing of the button 40. The button body 42 is generally a plate-shaped structure, which protrudes from one side of the mounting surface 411 and is close to one side surface 413, and one surface of the button body 42 is flush with the side surface 413. The pressing body 41 and the button body 42 are integrally formed parts. In this embodiment, the button body 42 is arranged perpendicularly to the pressing body 41. The cross-section of the button 40 (perpendicular to the length direction of the pressing body 41) is L-shaped, that is, the pressing body 41 and the button body 42 form an L-shaped structure. In other embodiments, the button body 42 and the pressing body 41 can be connected at an angle, and the mounting groove 15 is inclined to avoid interference with the button body 42.

[0057] Specifically, the pressing body 41 includes a first part 41a and a second part 41b. The first part 41a and the second part 41b are connected along the width direction of the pressing body 41. The button body 42 protrudes from the first part 41a. Along the thickness direction of the end frame 12, the width of the pressing body 41 is greater than the thickness of the button body 42, and the width of the first part 41a is equal to the thickness of the button body 42.

[0058] The distance between the two sides 413, and the sum of the widths of the first part 41a and the second part 41b, constitute the width L1 of the pressing body 41. The thickness L2 of the button body 42 is less than the width L1 of the pressing body 41. The thickness L2 of the button body 42 is approximately equal to the width of the mounting groove 15, ensuring that the button body 42 can move within the mounting groove. In this embodiment, the width L1 of the pressing body 41 is greater than or equal to 1 mm and less than or equal to 3 mm, such as 1.2 mm. The thickness L2 of the button body 42 is greater than or equal to 0.4 mm and less than or equal to 1.5 mm, such as 0.6 mm. The thickness L3 of the end frame 12 (side frame 11) is greater than or equal to 2.8 mm and less than or equal to 5 mm, such as 3.2 mm. It can also be understood that the thicknesses of the end frame 12 and the side frame 11 are different.

[0059] A limiting groove 422 is provided in the middle of the button body 42. The limiting groove 422 penetrates the button body 42 in the thickness direction and extends along the height direction of the button body 42 (width of the end frame 12). The limiting block 44 passes through the limiting groove 422. After the button 40 is installed in the mounting groove 15, the limiting block 44 protrudes from both ends of the button body 42 and is respectively held in the limiting hole 17 and the receiving groove 18. When the button 40 slides, the limiting groove 422 provides movement space for the button 40, and the limiting block 44 prevents the button 40 from sliding out of the mounting groove 15.

[0060] The button body 42 also has two retaining bodies 423, which are located at both ends of the button body 42 along its length and are used to hold the two latching parts 220. The two retaining bodies 423 are located on both sides of the limiting groove 422. The button body 42 also has two guide posts 425, which protrude from the end face facing away from the pressing body 41 and are spaced apart. The limiting groove 422 is located between the two guide posts 425. In this embodiment, the end face of the body facing away from the pressing body 41 has two recesses (not shown in the figure), and the two guide posts 425 protrude into the recesses, which can reduce the width of the button body 42 and save space in the housing 10. Two elastic bodies are sleeved on the two guide posts 425 for the reset of the button 40. The length direction of the retaining body 423 is perpendicular to the length direction of the guide posts 425 and the limiting groove 422.

[0061] Please refer to the following: Figure 10 for Figure 2 The diagram shows a cross-sectional view of the watch body and part of the strap at one angle. Figure 11 yes Figure 2 The diagram shows a cross-sectional view of the watch body and part of the strap from another angle.

[0062] The display screen 30 is mounted on the housing 10 and is sealed to the step 141 of the second side 14 with adhesive. The rear shell 20 is mounted on the housing 10, with its inner surface 22 facing the housing 10 and its periphery connected to the first side 13 with adhesive. The first surface 251 of the limiting strip 25 is opposite to the connecting end face 1521 of the second groove sidewall 152 and is connected with adhesive. The notch 24 of the rear shell 20 faces the first groove sidewall 151 and forms a gap with the first groove sidewall 151. The button 40 is installed in the mounting groove 15, with the button body 42 inserted into the mounting groove 15 between the first groove sidewall 151 and the second groove sidewall 152. The pressing body 41 closes the gap between the notch 24 and the first groove sidewall 151, and the pressing surface 412 protrudes from the outer surface 21 of the rear shell 20. That is, the pressing body 41 closes the opening of the mounting groove 15. In the thickness direction of the watch body 100, the orthographic projection of the pressing body 41 partially overlaps with the orthographic projection of the second groove sidewall 152.

[0063] It is understood that the second part, opposite to the limiting strip 25, has its second part 41b of the pressing body 41 projected onto the thickness direction of the housing 10 and partially overlaps with the connecting end face 1521. The abutment 1522 is located between the limiting strip 25 and the button body 42, and along the thickness direction of the housing 10, a portion of the limiting strip 25 and the abutment 1522 overlaps with the second part 41b. That is, the end frame 12 and the button 40 overlap in the thickness direction of the watch body 100. Along the length direction of the housing 10, the limiting block 44 protrudes from both ends of the button body 42 and is respectively engaged in the two limiting holes 17, thereby limiting the button 40 in the housing 10. One end of the elastic body 43 abuts against the button body 42, and the other end abuts against the bottom wall of the mounting groove 15, and has a pre-compression elastic force (the buckle 220 and the button 40 can maintain the pre-compression elastic force of the elastic body 43). The two retaining bodies 423 are located on the side of the two retaining holes 16 away from the pressing body 41.

[0064] The end 230 of the watch strap 200 is fitted into the recess 124, and the two second sub-ends 230b are respectively opposite to the two concave surfaces 1243. The buckle 220 passes through the retaining hole 16, and the hook 222 is engaged with the retaining body 423 and housed in the receiving groove 18 corresponding to the buckle 220. In the thickness and width directions of the watch body 100, the receiving groove 18 and the retaining body 423 limit the buckle 220. On the rectangular section, the hook 222 and the retaining body 423 achieve the engagement and limiting of the watch strap 200 and the case 10. Along the thickness direction of the housing 10, that is, the depth direction of the mounting groove 15, the pressing surface 412 of the pressing body 41 is pressed. The button body 42 slides along the mounting groove 15 and compresses the elastic body 43. The retaining body 423 slides along the mounting groove 15 and approaches the bottom wall 153 of the groove, so that it can be completely offset from the receiving groove 18. When the external force pulls the watch strap 200, the buckle part 220 disengages from the retaining body 423 and is pulled out of the housing 10 through the retaining hole 16, so the watch strap 200 can be removed. Among them, the end 230 of the watch strap 200 is installed in the recess 124, and the second sub-end 230b intersects with the first part and is inclined. It is equivalent to the two ends of the watch strap being inserted into the housing 10 and the middle being connected to the plane of the housing 10, which ensures the connection stability and also reduces the space occupied by the watch body in the length direction (Y-axis direction), leaving more space for the housing.

[0065] In this embodiment, the button 40 is L-shaped. In the thickness direction of the watch body 100, the pressing body 41 overlaps with the limiting strip 25. That is, the pressing body 41 overlaps with the mounting wall (second groove side wall 152) of the housing 10 in the thickness direction of the watch body 100. The width of the pressing body 41 is greater than the thickness of the button body 42. This avoids the button body 42 occupying too much space in the housing while reducing the length space occupied by the button 40 in the housing 10, and also ensures a wider button appearance width. In other words, the pressing body 41 of the button 40 has sufficient area to provide pressing contact. The thickness of the button body 42 is reduced compared to the width of the press body 41, avoiding the occupation of space in the length direction (Y-axis) of the housing (the thickness of the end frame 12 can be reduced). The space created by the thickness difference between the press body 41 and the button body 42 allows for a reduction in the thickness of the end frame 12. This reduces the thickness of the end frame 12 of the housing 10, thereby increasing the Y-axis dimension of the mounting cavity 101 of the housing 10, increasing the capacity of the housing 10, and providing sufficient space for battery volume, antenna clearance, etc. It also provides interconnection area for the connection between the watch band 200 and the watch body 100, ensuring the capacity of the watch body 100 while enhancing the connection stability between the watch band 200 and the watch body 100. Illustratively, the thickness of the end frame 12 can be reduced to 3.2mm, and the buttons 40 on both sides of the watch body 100 will have a reduced footprint in the housing 10, thus increasing bidirectional size benefits.

[0066] Please see Figure 12 Figure 13 and Figure 14 , Figure 12 for Figure 1 A schematic diagram of the watch body and part of the watch strap of the wearable device of the second embodiment shown; Figure 13 for Figure 12 The diagram shows an exploded view of the watch body and part of the watch strap in the second embodiment. Figure 14 for Figure 12 The second embodiment shown is an exploded view of the watch body and part of the watch strap from another angle.

[0067] In this embodiment, with Figure 2 and Figure 4 The difference between the watch body 100 of the wearable device in the first embodiment shown lies in the structure of the mounting groove 15 of the housing 10, the structure of the button 40, and the structure of the notch position on the back cover 20. It should be noted that components with the same structure as those in the first embodiment can be referred to in the description of the first embodiment. Specific orientations and shapes are not described in this embodiment; only the component and its mating relationships are introduced. For ease of understanding, components identical to those in the first embodiment are designated with the same reference numerals.

[0068] Please see Figure 12 Figure 13 and Figure 14 In this embodiment, the back cover 20 and the display screen 30 are respectively mounted on opposite sides of the thickness direction of the housing 10. The button 40 is mounted on the housing 10 and protrudes from the back cover 20. The button 40 can be moved towards the housing 10 to unlock the watch strap 200.

[0069] The rear shell 20 is a rectangular plate, including an outer surface 21, an inner surface 22, and an end face 23. A notch 24 is provided at the end of the rear shell 20. The notch 24 penetrates the outer surface 21, the inner surface 22, and the end face 23. In this embodiment, the notch 24 is formed by a portion of the rear shell 20, and abutment portions 27 are formed on both sides of the notch 24. The rear shell 20 also includes an abutment platform 26, which is formed within the notch 24. The surface of the abutment platform 26 faces the same direction as the inner surface 22, and in the thickness direction of the rear shell 20, the abutment platform 26 is recessed relative to the inner surface 22. The abutment platform 26 is used to engage with the housing 10 to limit the button 40. The notch 24 includes a mating surface 241 connected to the abutment platform 26, which faces the same direction as the end face 23, and is used to engage with the button 40.

[0070] The watch strap 200 and Figure 6 The watch strap 200 shown in the first embodiment has the same structure, including a strap body 210 and a buckle portion 220. The strap body 210 includes an end portion 230, which includes a first sub-end portion 230a and a second sub-end portion 230b. The buckle portion 220 protrudes from the surface of the first sub-end portion 230a. The buckle portion 220 consists of two hooks, and includes a main body (not shown) and hook portions 222.

[0071] In this embodiment, the housing 10 includes two oppositely arranged side frames 11, two oppositely arranged end frames 12, a first side 13 and a second side 14, and the two side frames 11 are respectively connected to the two end frames 12 to form a mounting cavity 101.

[0072] Please refer to the following: Figure 15 and Figure 16 , Figure 15 for Figure 13 A schematic diagram of the shell structure at one angle is shown; Figure 16 for Figure 15 The diagram shows another angle of the shell structure.

[0073] The end frame 12 includes a sub-side surface 121, an outer end surface 122, and an inner end surface 123. The sub-side surface 121 connects the outer end surface 122 and the inner end surface 123. The end frame 12 also includes a recess 124. The recess 124 includes a bottom wall 1241 and two side walls 1242, and the bottom wall 1241 has a concave surface 1243. The end 230 of the watch strap 200 is inserted into the recess 124, and the second sub-end 230b is opposite to the two concave surfaces 1243 respectively. They can be in contact or have tolerance gaps. The second sub-end 230b cooperates with the concave surfaces 1243 so that part of the end 230 of the watch strap 200 is inserted deeper into part of the case 10. Compared with the cooperation of two flat surfaces, it is more compact and avoids gaps between the watch strap 200 and the case 10 when the watch strap 200 is pulled by external force, which would affect the external appearance of the watch.

[0074] The end frame 12 also includes a mounting groove 19, two retaining holes 16, two limiting holes 17, and two receiving grooves 128. The mounting groove 19 is used to mount the button 40, and it is recessed from the sub-side 121 into the end frame 12. The groove opening of the mounting groove 19 (not shown in the figure) is located on the sub-side 121. In this embodiment, the mounting groove 19 is a rectangular groove that extends along the length direction of the end frame 12. The mounting groove 19 includes a first groove sidewall 191, a second groove sidewall 192, a groove bottom wall (not shown in the figure), and two groove end walls 194. Along the thickness direction of the end frame 12 (the length direction of the housing 10), the first groove sidewall 191 and the second groove sidewall 192 are spaced apart and opposite each other. Along the length direction of the end frame 12 (width direction of the housing 10), the two groove end walls 194 are spaced apart and opposite each other, and the two groove end walls 194 are connected between the first groove side wall 191 and the second groove side wall 192. The side of the first groove side wall 191 facing away from the mounting groove 19 is the bottom wall 1241 of the recess 124.

[0075] A limiting recess 196 is recessed on the wall surface of the first groove sidewall 191 facing the second groove sidewall 192. The limiting recess 196 is recessed towards the recess 124 and is positioned opposite to the recess 124. Two retaining holes 16 and one limiting hole 17 are all formed on the first groove sidewall 191 and penetrate the first groove sidewall 191 along the thickness direction of the end frame 12, that is, penetrating the bottom wall 1241 of the recess 124 and the bottom of the limiting recess 196. The limiting hole 17 is located between the two retaining holes 16.

[0076] A limiting strip 198 protrudes from the end face (partial sub-side face) of the free end of the second groove sidewall 192, extending along the length of the end frame 12. A protrusion 199 protrudes from a portion of the surface of the second groove sidewall 192 facing the first groove sidewall 191, extending towards the first groove sidewall 191. The end of the protrusion 199 facing away from the groove bottom wall is a clearance end 197, located on one side of the limiting strip 198. The surface of the clearance end 197 faces the same direction as the sub-side face and towards the groove bottom wall of the mounting groove 19. The clearance end 197 is lower than the sub-side face and the limiting strip 198. The clearance end 197 provides space for the movement of the button 40 within the mounting groove 19, and the limiting strip 198 abuts against the abutment platform 26 of the rear shell 20 to limit the button 40. In this embodiment, the protrusion 199 can both limit the position of the button 40 in the thickness direction of the end frame 12 and limit the button 40 when it is pressed into the mounting groove 19 to prevent excessive pressing.

[0077] Two receiving grooves 128 are recessed on the surface of the second groove sidewall 192 facing the first groove sidewall 191 and close to the two groove end walls 194. The two receiving grooves 128 correspond to the two retaining holes 16. A clearance end 197 is located between the two receiving grooves 128. Each receiving groove 128 includes a groove wall with a slope for fitting with the hook portion 222.

[0078] Both end walls 194 of the groove are provided with limiting steps 1941. The limiting steps 1941 face the same direction as the bottom wall of the groove and are both facing the opening of the mounting groove 19. The limiting steps 1941 have a height difference with the bottom wall of the groove. The limiting steps 1941 are used to cooperate with the button 40 to limit and move the button 40. The height of the limiting steps 1941 towards the bottom wall of the mounting groove 19 is equivalent to that of the clearance end 197. The second limiting hole 17 is recessed on the second groove side wall 192 between the two receiving grooves 128 and is opposite to the limiting hole 17 on the first groove side wall 191; the limiting hole 17 on the second groove side wall 192 is a blind hole.

[0079] The buckle 220 of the watch strap 200 can be inserted into the mounting slot 19 through the two retaining holes 16, and the hook 222 can be accommodated in the receiving slot 128 after being engaged with the button 40.

[0080] Please see Figure 17 and Figure 18 , Figure 17 for Figure 13 A schematic diagram of the button at one angle is shown. Figure 18 for Figure 17The diagram shows another structural view of the button. The button 40 includes a pressing body 41, a button body 42, and an elastic body 43. The pressing body 41 is a rectangular plate, including a mounting surface 411, a pressing surface 412, and two opposing side surfaces 413, which connect the mounting surface 411 and the pressing surface 412. The pressing surface 412 exposes the housing 10 to allow the button 40 to be pressed. The button body 42 is generally plate-shaped, protruding from one side of the mounting surface 411 and close to one side surface 413. The pressing body 41 and the button body 42 are integrally molded, and the cross-section of the button 40 is L-shaped, meaning the pressing body 41 and the button body 42 form an L-shaped structure.

[0081] The pressing body 41 includes a first part 41a and a second part 41b, which are connected. The button body 42 protrudes from the first part 41a. The width of the pressing body 41 is greater than the thickness of the button body 42, and the width of the first part 41a is equal to the thickness of the button body 42.

[0082] The width L1 of the press body 41 is greater than or equal to 1 mm and less than or equal to 3 mm, such as 1.2 mm. The thickness L2 of the button body 42 is greater than or equal to 0.4 mm and less than or equal to 1.5 mm, such as 0.6 mm. The width H1 of the button 40 is greater than or equal to 2.3 mm and less than or equal to 4 mm, such as 2.5 mm. The depth of the mounting groove 19 in this embodiment is 2.9 mm to 5.5 mm, and can be any value. The thickness L3 of the end frame 12 (side frame 11) is greater than or equal to 2.8 mm and less than or equal to 5 mm, such as 3.2 mm, which can also be understood as the end frame 12 and the side frame 11 having different thicknesses. The thickness H2 of the shell 10 is greater than or equal to 4 mm.

[0083] The button 40 also includes two second retaining bodies 423 and two first retaining bodies 424. The two second retaining bodies 423 protrude from both ends of the button body 42 along its length, extending away from the button body 42 and spaced apart from the mounting surface 411 of the pressing body 41. The two second retaining bodies 423 are used for engaging with the two latching portions 220. The two first retaining bodies 424 are located at opposite ends of the mounting surface of the pressing body 41 along its length (the length direction of the button 40), with the button body 42 positioned between and spaced apart from the two second retaining bodies 423. Specifically, the first retaining bodies 424 extend away from the mounting surface and are bent away from the button body 42. Along the width direction of the button 40, the second retaining bodies 423 and the first retaining bodies 424 are spaced apart and at least partially offset. The first retaining bodies 424 are used to engage with the limiting step 1941.

[0084] The button body 42 is also provided with two guide posts 425. The two guide posts 425 protrude from the end face facing away from the pressing body 41. Two elastic bodies 43 are sleeved on the two guide posts 425 for resetting the button 40.

[0085] Please refer to the following: Figure 19 , Figure 20 , Figure 19 for Figure 13 The image shows a cross-sectional view of the watch body and strap connected together. Figure 20 for Figure 13 The image shows a cross-sectional view of the watch body and part of the watch strap at one angle.

[0086] The button 40 is mounted in the mounting groove 19 of the housing 10. An elastic body 43 is sleeved on the guide post 425. One end of the elastic body abuts against the bottom wall of the mounting groove 19 and has a pre-compression elastic force. The second retaining body 423 is close to the bottom wall of the groove and is partially offset from the receiving groove 128 in the width direction of the button. The receiving groove 128 and the second retaining body 423 are partially opposite each other. The end of the second retaining body 423 faces the groove end wall 194 and can slide along the groove end wall 194. Along the width direction of the button 40, the first retaining body 424 is disposed opposite to the spaced limiting step 1941. The button body 42 is located between the protrusion 199 and the side wall of the first groove. Along the thickness direction of the housing 10, the clearance end 197 is spaced apart from the second part 41b. When the pressing surface 412 of the pressing body 41 is pressed, the button body 42 slides along the mounting groove 19 and compresses the elastic body 43. The second retaining body 423 slides along the mounting groove 19 and approaches the bottom wall of the groove, which can be completely offset from the receiving groove 128, that is, avoid the receiving groove 128, for the passage of the latching part 220. The first retaining body 424 abuts against the limiting step 1941. During this process, the latching part 220 and the button 40 are in the unlocked state.

[0087] The display screen 30 is mounted on the housing 10 and is sealed to the second side 14 with adhesive. The button body 42 of the button 40 is located within the limiting recess 196, and the pressing surface 412 protrudes from the outer surface 21 of the back cover 20. This can be understood as the pressing body 41 closing the opening of the mounting groove 19. Specifically, in the thickness direction of the watch body 100, the mounting surface 411 of the pressing body 41 is opposite to the limiting recess 196. Along the length direction of the housing 10, two receiving grooves 128 are aligned with two retaining holes 16; two second retaining bodies 423 partially obstruct the retaining holes 16.

[0088] The rear shell 20 is mounted on the housing 10, with its inner surface 22 facing the housing 10 and its periphery fixed to the first side surface 13 by an adhesive connection. The abutment platform 26 abuts against the limiting strip 198, and the abutment portions 27 on both sides of the notch 24 of the rear shell 20 press against two first retaining bodies 424, i.e., the first retaining bodies 424 are limited between the rear shell 20 and the limiting step 1941. The notch 24 of the rear shell 20 faces the first groove sidewall 191 and forms a gap with it. The pressing body 41 is located within this gap. Along the length of the housing 10, the mating surface 241 faces the pressing body 41 and is opposite to the side of the pressing body 41. Within the thickness square of the housing 10, a portion of the mounting surface 411 of the pressing body 41 faces the clearance end 197, and the pressing surface 412 of the pressing body 41 protrudes from the rear shell 20. The button body 42 is located between the protrusion 199 and the first groove sidewall 191. The protrusion 199 is designed to fit the L-shaped button 40, which can save the thickness space of the end frame 12. It can be understood that the thickness of the pressing body 41 of the button 40 assembled in the end frame 12 is the thickness of the button 40.

[0089] The end 230 of the watch strap 200 is fitted into the recess 124, and the second sub-end 230b is opposite to the recess 1243. It can be released or may have a gap or tolerance gap. The buckle 220 passes through the retaining hole 16, and the hook 222 pushes and engages with the second retaining body 423. The hook 222 is received in the receiving groove 128 corresponding to the buckle 220. The hook 222 pushes the second retaining body 423, which in turn pushes the button body 42 towards the bottom wall of the groove, compressing the elastic body 43. When the external force is removed, the elastic body 43 restores its elasticity and pushes the button 40 to reset. The buckle 220 engages with the second retaining body 423, and the abutting part 27 abuts against the first retaining body 424. The elastic body 43 is in a compressed state. In one embodiment, the end face of the button body 42 facing away from the pressing body 41 is flush with the wall 161 of the retaining hole 16 facing the pressing body 41 (a certain tolerance is allowed). Alternatively, in the direction from the bottom wall of the mounting groove 19 to the opening of the mounting groove 19 (that is, in the negative direction of the Z-axis), the end face of the button body 42 is lower than the wall 161 of the hole, that is, there is a gap between the wall 161 of the hole and the end face of the button body 42. This can reduce the height of the button body 42, thereby reducing the width of the end frame.

[0090] When the watch strap 200 needs to be removed, press the pressing surface 412 of the button 40 from the back cover 20 toward the display screen 30. The pressing body 41 drives the button body 42 to move toward the display screen 30 (towards the bottom wall of the slot). The button body 42 compresses the elastic body 43. The first retaining body 424 moves toward the limiting step 1941. The second retaining body 423 moves toward the bottom wall of the slot and disengages from the hook 222 of the buckle 220. The supporting part 27 disengages from the first retaining body 424, and the first retaining body 424 moves to the limiting step 1941. The buckle completely disengages from the second retaining body 423. Pulling the watch strap 200 with external force will remove the watch strap 200 from the watch body 100.

[0091] It should be noted that the first retaining body 424 cooperates with the limiting step 1941 to limit the button 40 in the thickness direction of the watch body 100, preventing the button 40 from detaching from the mounting groove 19. Therefore, it is unnecessary to set a limiting groove (extending along the width direction of the body) and a limiting block (as in the first embodiment) on the button body 42 of the button 40 to limit the position of the button 40 in the thickness direction of the watch body 100. This allows for a further reduction in the width (Z-axis dimension) (thickness of the watch body) of the button body 42, i.e., a reduction in the width of the button 40. Correspondingly, the depth of the mounting groove 19 can be reduced, further reducing the thickness dimension of the housing 10, and thus reducing the overall thickness of the watch body 100, which is beneficial for the thinner design of the watch. Furthermore, the button 40 does not need a limiting groove, which helps improve the strength of the button 40. Also, eliminating the limiting block and the need for limiting holes on the housing 10 allows for a reduction in the thickness of the end frame 12 of the housing, providing more space for the receiving cavity and also improving the strength of the end frame. In summary, the combination of button 40 and mounting groove 19 on the back cover 20 in this embodiment can save internal space of the housing 10 in the Y-axis direction and also save the thickness dimension of the housing 10, thereby facilitating the thin design of the watch body or the multi-functional design of the watch.

[0092] Please see Figure 21 , Figure 21 for Figure 1 The diagram shows a cross-sectional view of the watch body and part of the watch strap of a third embodiment of the wearable device. This embodiment differs from the first embodiment in that the button body is inclined relative to the pressing body, and the mounting groove is inclined relative to the thickness direction of the watch body. The following description focuses only on the differences between this embodiment and the first embodiment. Furthermore, to better illustrate the structure of the button, mounting groove, and end frame, structures identical to those in the first embodiment are represented by the same reference numerals.

[0093] In this embodiment, the mounting groove 15 is inclined relative to the thickness direction (Z-axis direction) of the watch body 100, that is, the extension direction of the groove sidewall of the mounting groove 15 (which can also be the groove depth direction, i.e., the direction from the groove opening to the bottom wall of the groove) is inclined, or it can be understood as inclined relative to the height direction of the end frame 12. Specifically, the first groove sidewall 151 and the second groove sidewall 152 are inclined relative to the thickness direction of the watch body 100. The inclination angle C between the mounting groove 15 and the thickness direction of the watch body 100 is greater than or equal to 2 degrees and less than or equal to 20 degrees, such as 10 degrees. The bottom wall 15A of the mounting groove 15 is parallel to the width direction or length direction of the watch body 100 (in this embodiment, the second side 14 and the surface of the display screen are also parallel to the width direction or length direction of the watch body 100). The first groove sidewall 151 and the second groove sidewall 152 are parallel to each other and are set at an angle (not a 90-degree angle) to the bottom wall 15A, that is, the first groove sidewall 151 and the second groove sidewall 152 are inclined relative to the bottom wall 15A. This can be understood as the wall surfaces of the first groove sidewall 151 and the second groove sidewall 152 being set at an angle to the wall surface of the groove bottom wall 15A. It can also be understood as the mounting groove 15 being inclined relative to the mounting cavity 101.

[0094] In this embodiment, along the thickness direction of the watch body 100, i.e., the Z-axis direction, the button body 42 (the direction of the height extension of the body, i.e., the direction in which the button body 42 protrudes from the pressing body 41, Z-axis direction) is inclined relative to the thickness direction of the watch body 100, and the inclination angle is greater than or equal to 2 degrees and less than or equal to 20 degrees. Specifically, the pressing surface 412 of the pressing body 41 of the button 40 is an arc-shaped surface, and the mounting surface 411 can be either a slope or a plane. In this embodiment, the mounting surface 411 is a slope. It can be understood that the button 40 is roughly a wedge-shaped block, and the thickness of the first part 41a is less than the thickness of the second part 41b. The pressing body 41 is at an angle to the thickness direction of the watch body, i.e., it is not parallel. The button body 42 protrudes from the mounting surface 411, specifically located in the first part 41a. The button body 42 is connected to the mounting surface 411 at an angle. In other embodiments, the button body 42 is inclined relative to the thickness direction of the watch body 100, and the angle between the button body 42 and the mounting surface 411 can also be a right angle, as long as it fits the mounting groove and there is no friction. In other embodiments, the pressing surface 412 of the pressing body 41 can also be a plane. That is to say, the inclined mounting groove 15 and the button 40 with an inclined body in this embodiment are applicable to the first embodiment.

[0095] In this embodiment, the two surfaces 426 of the button body 42 in the thickness direction are parallel (allowing for certain tolerances). The end face 427 of the button body 42 facing away from the pressing body 41 connects to the two surfaces 426 in the thickness direction of the button body 42, and the end face 427 and the surface 426 are set at an angle (not a 90-degree angle). It can be understood that the cross-section of the button body 42 in the height direction is a parallelogram, and the inclination of the button body 42 can be understood as the inclination of the surface 426. Among them, the two surfaces 426 in the thickness direction of the button body 42 are inclined at an angle to the thickness direction of the housing 10, and the end face of the button body 42 facing away from the pressing body 41 (connecting the two surfaces in the thickness direction of the button body 42) is parallel to the bottom wall of the mounting groove 15. One surface 426 is connected to the mounting surface 411 at an angle A, and the other surface 426 is connected to the side of the pressing body 41 that connects the pressing surface 412 and the mounting surface 411, and is smoothly connected to the side of the pressing body 41. The angle between the button body 42 and the pressing body 41 in this embodiment is designed to adapt to the shape of the housing and the mounting groove, so as to better match the mounting groove 15 and the housing 10.

[0096] The connection between the outer end face 122 of the end frame 12 and the sub-side face is an arc-shaped surface, specifically the free end face of the first groove sidewall 151 (facing away from the bottom wall of the mounting groove 15) is an arc-shaped surface.

[0097] In this embodiment, the outer surface 21 of the rear shell 20 is an arc-shaped surface, specifically the position of the outer surface 21 near the end face 23 (end frame 12) is an arc-shaped surface.

[0098] Button 40 is inserted into mounting slot 15, and button body 42 is inserted into mounting slot 15 between the first slot sidewall 151 and the second slot sidewall 152. The angle of inclination of button body 42 relative to pressing body 41 matches the angle of inclination of mounting slot 15, and will not affect the assembly of button body 42 and mounting slot 15. In this embodiment, the angle of inclination of button body 42 is the same as the angle of inclination of mounting slot 15 (first slot sidewall 151 and second slot sidewall 152). The outer end face 122, sub-side face 121, pressing face 412 and outer surface 21 of back cover 20 located on one side of mounting slot 15 are connected in sequence and together form an arc-shaped outer contour surface. This outer contour surface is the edge contour surface between the sidewall and back of the watch body. It should be noted that the arc-shaped surface at the connection between the outer end face and sub-side face 121, the arc of pressing face 412 and the arc of outer surface 21 of back cover 20 are the same arc, which can also be understood as the profile of the arc-shaped outer contour surface being an arc-shaped line or a Bezier curve. The rounded outer contour surface can enhance the aesthetic appearance of the watch body 100. In this embodiment, the pressing body 41 of the button 40 and the button body 42 are inclined, and the corresponding mounting groove 15 is set as an inclined groove. While ensuring the depth of the mounting groove 15, the height dimension of the occupied end frame can be reduced, which means the thickness dimension of the housing 10 is reduced, which is more conducive to the thinner design of the watch body.

[0099] Please see Figure 22 , Figure 22 for Figure 1 The diagram shows a cross-sectional view of the watch body and part of the watch strap in the fourth embodiment of the wearable device. The difference between this embodiment and the third embodiment lies in the angle of the mounting slot.

[0100] In this embodiment, in the height direction of the end frame 12, i.e., the thickness direction of the watch body 100, and in the depth direction of the mounting groove 15, the extension direction of the mounting groove is parallel to the height of the end frame 12, i.e., parallel to the thickness direction of the watch body 100 (a certain tolerance is allowed). Specifically, the bottom wall 15A of the mounting groove 15 is parallel to the width or length direction of the watch body 100 (in this embodiment, the second side 14 and the surface of the display screen are also parallel to the width or length direction of the watch body 100), and the first groove sidewall 151 and the second groove sidewall 152 are parallel to each other and perpendicular to the bottom wall 15A. It can be understood that the wall surface of the first groove sidewall 151 and the wall surface of the second groove sidewall 152 form an angle of 90 degrees with the wall surface of the bottom wall 15A (a certain tolerance is allowed, such as 88 degrees or 91 degrees).

[0101] In this embodiment, the button body 42 is connected to the mounting surface 411 at an angle. The two surfaces of the button body 42 in the thickness direction are parallel, and the end face of the button body 42 facing away from the pressing body 41 connects to the two surfaces in the thickness direction, with the end face perpendicular to the two surfaces; that is, the button body 42 is a rectangular prism. This can be understood as the button body 42 being parallel to the thickness direction of the watch body 100, and the two surfaces being parallel to the thickness direction of the watch body 100. Specifically, the end face of the button body 42 facing away from the pressing body 41 (connecting the two surfaces in the thickness direction of the button body 42) is parallel to the bottom wall of the mounting groove 15. The two surfaces of the button body 42 in the thickness direction are parallel to the thickness direction of the housing 10 (allowing for certain tolerances). In this embodiment, the mounting surface is not planar; the connection between the mounting surface corresponding to the first part 41a and the mounting surface corresponding to the second part 41b has an angle.

[0102] The outer end face 122 and the sub-side face 121 of the end frame 12 are arc-shaped surfaces. Specifically, the free end face (facing away from the bottom wall of the mounting groove 15) of the first groove sidewall 151 is an arc-shaped surface. In this embodiment, the outer surface 21 of the rear shell 20 is an arc-shaped surface. Specifically, the position of the outer surface 21 near the end face 23 is an arc-shaped surface.

[0103] Button 40 is inserted into mounting slot 15, and button body 42 is inserted into mounting slot 15 between the first slot sidewall 151 and the second slot sidewall 152. The first slot sidewall 151 and the second slot sidewall 152 are parallel to and opposite to the two surfaces respectively (allowing certain tolerances). Mounting slot 15 is a rectangular slot, and button body 42 is a rectangular prism, which will not affect the assembly of button body 42 and mounting slot 15. The sub-side surface 121, pressing surface 412, and outer surface 21 of back cover 20 located on one side of mounting slot 15 are connected sequentially along the length of the end frame and together form an arc-shaped outer contour surface. This outer contour surface is the edge contour surface between the sidewall and back of the watch body. The rounded outer contour surface can improve the appearance of the watch body 100.

[0104] Please see Figure 23 , Figure 23 yes Figure 1 The diagram shows a cross-sectional view of the watch body and part of the watch strap in the fifth embodiment of the wearable device. In this embodiment, with... Figure 4 Unlike the first embodiment of the watch body, the pressing body of the button 60 has the same thickness as the main body, and the connection between the back cover 20 and the housing 10 is completely offset from the button 60. Compared to the fit between the button 60 and the housing 10 in the first embodiment, the thickness of the end frame 12 in this embodiment needs to reserve a mounting groove 19 larger than the width of the button 60. In the thickness direction of the housing 10, the button 60 and the housing do not overlap, but are arranged side-by-side along the Y direction. In this embodiment, the button adopts... Figure 4The first embodiment uses a limiting block and a limiting groove for the button 40, thus requiring a reserved space for the limiting groove in the width direction of the button 60, which increases the width of the button 40 compared to the second embodiment. In this embodiment, the width L4 of the button 60 is greater than or equal to 1.5 mm and less than or equal to 3 mm, the thickness L5 of the end frame 12 is greater than 4.5 mm and less than or equal to 7.5 mm, and the thickness H3 of the housing 10 is greater than 7 mm.

[0105] The above are merely some embodiments and implementation methods of this application. The scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
