The display module 120 covers the installation space and is connected to an end of the middle frame 111 facing away from the rear cover 113, and the middle frame 111 is surrounded on the display module 120. The display module 120 can be used to display information and provide an interactive interface for a user. The electronic device 100 may include two or more biosensors that may be used to detect biological data such as heart rate, respiratory rate, blood pressure, or body fat. The rear cover 113 may be provided with a detection window of a biosensor such as a heart rate sensor or a blood oxygen sensor. In some embodiments, the biosensor may also be used to detect a state of motion, for example, for step counting. In other embodiments, the wearable device 10 may be a smart band or the like.

The Display screen module 120 may further include a Display screen and a cover plate covering the Display screen, the Display screen may be an LCD (Liquid Crystal Display) screen or an OLED (Organic Light-Emitting Diode) screen, and the cover plate may be a glass cover plate or a sapphire cover plate. The cover plate is transparent and has relatively high light transmittance, for example, the light transmittance of the cover plate is over 80%. The display module 120 may have a touch function, but the touch function is not required, and the display module 120 is not required.

The middle frame 111 is substantially rectangular frame-shaped, and four corners of the rectangle may be processed into arc transition through a chamfering process, so that the wearable device 10 has good appearance characteristics. In other embodiments, the middle frame 111 may have a circular frame shape. The side of the middle frame 111, i.e., the surface facing away from the installation space, may be provided with a fitting structure for installing the strap 200, and the strap 200 can form a reliable connection with the middle frame 111 through the fitting structure of the middle frame 111 to reliably wear the electronic device 100 to the hand of the user. In some embodiments, strap 200 can also be relatively easily detached from middle frame 111 to allow a user to easily replace strap 200. For example, the user may purchase straps 200 of various styles and replace the straps 200 according to the use scene to improve convenience of use. For example, a user may use more formal strap 200 in formal situations and may use a casual style strap 200 in recreational situations.

With continued reference to fig. 1 and fig. 2, in the embodiment of the present application, the strap 200 includes two straps, two opposite ends of the electronic device 100 are respectively provided with the mounting groove 130, one end of each of the two straps 200 is connected to the electronic device 100, and ends of the two straps 200 facing away from the electronic device 100 may be fastened together to form a receiving space, so that the electronic device 100 is worn on the wrist of the user through the straps 200. In other embodiments, the strap 200 may be a one-piece structure, one end of the strap 200 is connected to one end of the electronic device 100, the other end of the electronic device 100 may be provided with a connector for the strap 200 to pass through (see fig. 15), the free end of the strap 200 may penetrate and pass through the connector and be fixed to another position of the strap 200 to form an accommodating space, and the size of the accommodating space is easily adjusted to facilitate wearing by a user.

Referring to fig. 3, the mounting groove 130 may include a key groove 130a and a groove 130b communicating with each other, and the key groove 130a extends to an outer surface of the rear cover 113, i.e., the key groove 130a extends to a surface of the rear cover 113 that can be touched by a user. Groove 130b opens in center frame 111, and strap 200 can be attached to electronic device 100 from groove 130b and detached from groove 130 b. Specifically, in the embodiment, the mounting slots 130 can be taken as a reference, the two mounting slots 130 are oppositely disposed at two ends of the electronic device 100 in the width direction, and the display module 120 and the rear cover 113 of the electronic device 100 are respectively disposed at two ends of the electronic device 100 in the thickness direction. For simplicity, the width direction of the electronic device 100 can be regarded as a first direction, and the thickness direction of the electronic device 100 can be regarded as a second direction, i.e., the first direction and the second direction are perpendicular to each other.

In this embodiment, the strap 200 can be fitted into the groove 130b in the first direction, and the strap 200 is restrained to the case 110. In the embodiment of the present application, the first direction and the second direction are only used as references for clearly and concisely describing the positions of the strap 200 and other components relative to the middle frame 111, and should not be considered as a strict limitation on the technical solution. For example, in other embodiments, the width direction of the electronic device 100 need not be the first direction, or the thickness direction of the electronic device 100 need not be the second direction, and in other embodiments, the first direction and the second direction may form an acute angle.

In embodiments where the electronic device 100 includes the display screen module 120, the key slot 130a may also extend to the outer surface of the cover plate of the display screen module 120 without extending to the rear cover 113, or the key slot 130a and the groove 130b may all be located in the middle frame 111.

Referring to fig. 4, in the present embodiment, the electronic device 100 includes a locking structure 140 disposed in the mounting groove 130. Referring to fig. 5, the strap 200 includes a strap body 210 and a connector 220, and the connector 220 can be inserted into the mounting slot 130 and cooperate with the locking structure 140 to restrain the strap 200 to the housing 110 of the electronic device 100. Further, referring to fig. 3 and 4, the locking structure 140 includes a key 141 exposed from the housing 110 and a limiting member 143 capable of linking with the key 141. The key 141 is disposed in the key slot 130a, and the stopper 143 is disposed in the groove 130 b. When pressed, the button 141 can move into the housing 110 and drive the limiting member 143 to move in the mounting slot 130, so that the connector 220 is disengaged from the locking structure 140, and the strap 200 can be detached from the electronic device 100.

In some embodiments, the connection head 220 can be directly inserted into the groove 130b and drives the position-limiting member 143 to move during the insertion process, so as to achieve the position-limiting engagement between the connection head 220 and the position-limiting member 143. In other embodiments, the user needs to press the button 141 to drive the stopper 143 to move through the button 141 before the connector 220 of the strap 200 is inserted into the groove 130 b.

In the embodiment of the present application, the restriction of one object to another object can be simply understood as that one object can limit the moving range of the other object, and the two objects are difficult to be separated under normal conditions. For example, in this embodiment, strap 200 is restrained to housing 110 meaning that housing 110 may limit the range of movement of strap 200 so that strap 200 does not easily disengage from housing 110 under normal use conditions. The positive fit is not limited to a fixed connection, i.e., the positions of the two objects of the positive fit need not be fixed relative to each other, e.g., the strap 200 can be rotated relative to the housing 110 with the strap 200 being restrained to the housing 110.

In some embodiments, electronic device 100 may include a bezel 150 that is removably coupled to housing 110. The baffle 150 is disposed in the groove 130b and covers at least a portion of the stopper 143, the baffle 150 can limit the movement of the locking structure 140 in the groove 130b, so that the locking structure 140 can move smoothly in the groove 130b, and the baffle 150 can further improve the appearance integrity of the electronic device 100. The cross section of the baffle 150 may be a track shape, and a connecting hole and a through hole 150a corresponding to at least a portion of the connector 220 may be formed thereon. The attachment holes may be used to receive threaded fasteners to provide removable attachment of the baffle 150 to the housing 110.

In the present embodiment, the baffle 150 is fitted into the groove 130b from the outside of the housing 110. In other embodiments, the baffle 150 may be disposed on a side of the housing 110 facing away from the groove 130b, that is, the baffle 150 may be disposed on a side of the housing 110 facing the circuit board or the battery to facilitate the installation of the locking structure 140 on the housing 110. The side of the locking structure 140 facing away from the baffle 150 may be limited by the housing 110 at the groove 130 b. In other embodiments, the baffle 150 may be absent, for example, by using the housing 110 at the groove 130b to limit the position of the locking structure 140 and the connector 220.

With continued reference to fig. 5, the connecting head 220 includes a body 221, a mating portion 223, and a cushioning portion 225, the body 221 being generally racetrack-shaped in cross-section. The body 221 has a mating surface 221 a. The tape body 210 is connected to a side of the body 221 facing away from the mating surface 221 a. Referring also to fig. 6, after strap 200 is mounted to electronic device 100, mating surface 221a is disposed opposite to bezel 150. In other words, mating surface 221a faces the inside of electronic device 100 after strap 200 is mounted to electronic device 100. The engaging portion 223 is connected to the body 221 and protrudes from the engaging surface 221a, and the engaging portion 223 is used for engaging with the limiting member 143 of the locking structure 140, so that the connecting head 220 is limited to the electronic device 100, and the binding band 200 is limited to the electronic device 100. After the connector 220 is limited to the electronic device 100, the fitting portion 223 penetrates through the baffle 150. The buffer portion 225 is connected to the body 221 and protrudes out of the fitting surface 221a, and the buffer portion 225 is used for filling a gap between the fitting surface 221a and the baffle 150, so that the body 221 can press the baffle 150 through the buffer portion 225, thereby realizing tight fit between the connector 220 and the baffle 150, preventing the connector 220 from shaking in the mounting groove 130, and preventing the gap between the body 221 and the baffle 150 from causing friction abnormal sound.

In some embodiments, the body 221 and the mating portion 223 are made of metal and are integrally formed, for example, the body 221 and the mating portion 223 may be formed by powder metallurgy. The material of the buffer 225 may be silicon gel, plastic, rubber, or the like. The buffer portion 225 can elastically deform when being squeezed, and then is filled in the gap between the fitting surface 221a and the baffle 150, so that the connector 220 and the baffle 150 can be tightly fitted to prevent the connector 220 from shaking. For example, in the present embodiment, the main body 221 and the engaging portion 223 may be made of aluminum alloy and integrally formed, and the buffer portion 225 may be made of soft plastic. Wherein, the plastic with Shore hardness below 98A can be regarded as soft plastic. The filling of the buffer portion 225 may be simply understood as the buffer portion 225 being accommodated in the gap between the mating face 221a and the baffle plate 150, but the buffer portion 225 is not required to completely fill the gap between the mating face 221a and the baffle plate 150. The buffer portion 225 acts on the gap between the absorbing baffle 150 and the mating surface 221a to provide a suitable pressing force. The pressing force makes the body 221 and the baffle 150 have a tendency to move away from each other, i.e. the connector 220 has a tendency to move towards the outside of the electronic device 100, so that the fitting portion 223 abuts against the limiting member 143, thereby preventing the connector 220 from easily shaking the housing 110 or generating friction noise during use.

Referring to fig. 4 and 5, the fitting portion 223 has a connection surface 223a, and the fitting portion 223 is provided with a recessed region 223b on the same side as the connection surface 223a, the recessed region 223b being located between the fitting surface 221a and the connection surface 223 a. During the process that the connecting head 220 is installed in the groove 130b along the first direction, the connecting surface 223a drives the locking structure 140 to move in the second direction relative to the housing 110, so that the limiting member 143 moves away from the key 141; after the engaging portion 223 moves a distance into the housing 110, the recessed area 223b of the engaging portion 223 moves to the position of the limiting element 143, the limiting element 143 is driven to move in the direction of the key 141 (i.e. the direction opposite to the second direction), and then enters the recessed area 223b, and the recessed area 223b receives at least a portion of the limiting element 143 to achieve the limiting of the locking structure 140 and the connecting head 220 (refer to fig. 13).

In some embodiments, the electronic device 100 includes an elastic member 160, such as a spring, or a spring sheet, or an elastic column, and the elastic member 160 is used to drive the position-limiting member 143 to move toward the direction of the key 141 (i.e., the direction opposite to the second direction), so that the position-limiting member 143 can enter the recessed area 223b of the engaging portion 223. After the limiting member 143 enters the recessed area 223b to limit the connecting head 220 on the housing 110, the elastic member 160 may be in a compressed state, so that the connecting head 220 is reliably limited on the electronic device 100, and the connecting head 220 is prevented from being easily removed from the electronic device 100. Of course, when the connecting head 220 is limited to the housing 110, the elastic member 160 may be in a natural extension state.

In other embodiments, the elastic member 160 may be replaced with a magnetic member. For example, the stopper 143 may be provided with a magnet, and the housing 110 may be provided with another magnet, and like magnetic poles of the two magnets are disposed to face each other, thereby generating a magnetic repulsive force between the two magnets. After the engaging portion 223 moves a certain distance into the housing 110, the recessed area 223b of the engaging portion 223 moves to the position of the limiting member 143, and the limiting member 143 is driven by the magnetic repulsion between the two magnets to move toward the direction of the key 141, and then enters the recessed area 223 b. After the position-limiting member 143 enters the recessed area 223b to position the connecting head 220 on the housing 110, a magnetic repulsion force still exists, so that the connecting head 220 is reliably positioned on the electronic device 100, and the connecting head 220 is prevented from being easily separated from the electronic device 100.

In the present embodiment, the engagement portion 223 has a substantially columnar shape, and the connection surface 223a is a flat surface and forms an acute angle with the longitudinal extension direction of the engagement portion 223. During the process of installing the fitting portion 223 into the through hole 150a of the baffle 150, the connecting surface 223a forms an acute angle with the moving direction of the limiting member 143, that is, the connecting surface 223a forms an acute angle with the second direction. The limiting member 143 may have another connecting surface 143a, and the other connecting surface 143a may be a plane or an arc surface. For example, in the present embodiment, the connection surface 223a and the other connection surface 143a are both planar surfaces, and the planar surfaces and the movement direction of the limiting member 143 relative to the housing 110, i.e. the second direction, form an angle of about 45 degrees, so that the force conditions of the limiting member 143 and the connection head 220 are better, and the limiting member 143 can move smoothly.

It can be understood that one of the connection surface 223a of the matching portion 223 and the other connection surface 143a of the limiting member 143 is a plane and forms an acute angle with the movement direction of the limiting member 143 in the housing 110, that is, the second direction, and in the process that the connector 220 is installed in the installation slot 130 along the first direction, the plane can convert the movement of the connector 220 into the housing 110 into the movement of the limiting member 143 along the movement direction perpendicular to the connector 220, that is, the second direction, so that the limiting member 143 moves away from the key 141, and the limiting matching between the limiting member 143 and the connector 220 is further achieved.

It will be appreciated that the connection surface 223a and the further connection surface 143a are not essential. For example, the cross-sectional area of the end of the engaging portion 223 far from the body 221 may be kept consistent, i.e. the connecting surface 223a is absent, and the cross-section of the limiting member 143 may be rectangular, i.e. the other connecting surface 143a is absent. In the process of installing the binding band 200 on the electronic device 100, the user needs to press the key 141 to retract the key 141 in the key slot 130a along the second direction, so as to drive the limiting member 143 to move in the groove 130b, and then install the connector 220 in the groove 130b at a predetermined position. When the connector 220 reaches the predetermined position, the key 141 is released, and the limiting member 143 can be driven to move in the reverse direction of the second direction to enter the recessed area 223b of the engaging portion 223, so as to achieve the limiting engagement between the connector 220 and the electronic device 100.

During the process of detaching the strap 200, the user may press the key 141 to retract the key 141 into the key slot 130a along the second direction, and the key 141 may drive the limiting member 143 to move along the second direction and exit the recessed area 223b of the engaging portion 223. After the limiting member 143 exits the recessed area 223b, the user may pull the strap 200 in the first direction, so as to detach the connector 220 from the electronic device 100.

It is understood that the linkage between the key 141 and the stopper 143 can be implemented in various ways. For example, in some embodiments, the key 141 is fixedly connected to the stopper 143. The fixed connection includes but is not limited to a threaded connection, a snap connection, an adhesive, a welding, and the like. In other embodiments, the position-limiting member 143 and the key 141 may not be assembled. For example, when the strap 200 is retained on the electronic device 100, there may be a gap between the retaining member 143 and the key 141 in the second direction. When the binding band 200 needs to be detached, the key 141 is pressed to move the key 141 to abut against the stopper 143, so that the stopper 143 can be driven to exit from the concave region 223b of the engaging portion 223. Of course, in some embodiments, when the strap 200 is limited to the electronic device 100, in the second direction, the limiting member 143 may abut against the key 141 or abut against the key 141 through an intermediate component, so that an end surface of the key 141 exposed to the housing 110 can be flush with a surface of the housing 110 at the key slot 130a, thereby improving appearance characteristics of the electronic device 100.

With reference to fig. 5, in the present embodiment, two engaging portions 223 are provided, and the two engaging portions 223 are spaced apart from each other.
