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 surface of the middle frame 111, i.e., the surface facing away from the receiving cavity 11a, may be provided with a fitting structure for mounting the strap assembly 200, and the strap assembly 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.

Referring to fig. 5 and 6, in some embodiments, the middle frame 111 is provided with a vent hole 11c communicated with the receiving cavity 11a, and the vent hole 11c extends to a surface of the middle frame 111 opposite to the receiving cavity 11a. Further, in the present embodiment, one end of the vent hole 11c is exposed to the bottom of the mounting groove 11b, in other words, the vent hole 11c communicates the mounting groove 11b and the housing cavity 11a. Referring to fig. 7, the electronic device 100 further includes a waterproof and air-permeable module 150 and a baffle 160, wherein the waterproof and air-permeable module 150 covers a side of the vent hole 11c facing away from the receiving cavity 11a and is connected to the middle frame 111. Referring to fig. 8, 9 and 10, in an embodiment, the baffle 160 covers the waterproof and air-permeable module 150 and has a gap 11d with the waterproof and air-permeable module 150, and the baffle 160 is fixedly connected to the middle frame 111.

Referring to fig. 11, the waterproof and breathable module 150 may include a reinforcing sheet 151, a first adhesive layer 153, a waterproof and breathable film 155, and a second adhesive layer 157, which are sequentially stacked. Referring also to fig. 10, the waterproof and breathable module 150 is fixedly connected to the middle frame 111 through a second adhesive layer 157. The waterproof breathable film 155 is made of a waterproof polymer material, and has air permeability but can prevent water from permeating, so that the air pressure between the inside and the outside of the electronic device 100 can be balanced, and the air pressure inside and outside the electronic device 100 can be kept consistent. In the present embodiment, the reinforcing sheet 151 is made of PET (Polyethylene terephthalate), which can provide a certain structural rigidity for the waterproof and breathable module 150, so as to prevent the waterproof and breathable module 150 from being easily deformed, thereby facilitating the assembly of the waterproof and breathable module 150 and protecting the waterproof and breathable film 155 to ensure the operational reliability of the waterproof and breathable module 150. Of course, the reinforcing sheet 151 may be replaced with other types of plastics having similar functions. Further, in this embodiment, the first adhesive layer 153 and the second adhesive layer 157 are both made of adhesive, the first adhesive layer 153 is used to fixedly connect the reinforcing sheet 151 to the waterproof breathable film 155, and the second adhesive layer 157 is used to fixedly connect the waterproof breathable module 150 to the middle frame 111, so as to reliably fix the waterproof breathable module 150 to the middle frame 111. Further, the reinforcing sheet 151, the first adhesive layer 153, and the second adhesive layer 157 are provided with holes for ventilation at positions corresponding to the ventilation holes 11c, so that air can smoothly permeate through the waterproof ventilation module 150 via the waterproof ventilation film 155. Of course, in other embodiments, the reinforcing sheet 151 and the first adhesive layer 153 may be absent.

In some embodiments, the waterproof and breathable module 150 and the baffle 160 may both have a sheet shape, and the outer contours of the two are similar in shape. For example, in the present embodiment, the waterproof and breathable module 150 and the baffle 160 are rectangular with rounded corners. In other embodiments, the waterproof, breathable module 150 and the baffle 160 may be similar and take on other shapes, such as circular or oval or polygonal. In other embodiments, the waterproof and breathable modules 150 and the baffle 160 may have different shapes, for example, the waterproof and breathable modules 150 may have a disk shape, and the baffle 160 may have a rounded rectangular shape.

Further, referring to fig. 7, in the present embodiment, the baffle 160 is provided with a through hole 160a for ventilation at a position corresponding to the ventilation hole 11c, so that air can flow between the through hole 160a, the waterproof and breathable module 150, and the housing cavity 11a. In the present embodiment, a plurality of through holes 160a are provided, and the plurality of through holes 160a are arranged in a circular array and provided corresponding to the vent holes 11 c. This arrangement may avoid weakening the structure of the baffle 160 too much, thereby increasing the structural strength of the baffle 160 and facilitating the flow of air. Of course, this arrangement is not essential, and for example, the through-hole 160a may be provided in one and the cross-sectional area of the through-hole 160a is equal to or larger than that of the vent hole 11 c. Of course, the through-hole 160a is not necessary. For example, the baffle 160 may include two or more separately disposed sheets, and a plurality of sheets are distributed along the outer circumference of the waterproof and breathable module 150 and cover at least a portion of the waterproof and breathable module 150.

Further, strap assembly 200 is attached to center frame 111 and covers shield 160. In other words, after strap assembly 200 is assembled with electronic device 100, barrier 160 may not be exposed, which may improve the appearance integrity of wearable device 10. Of course, it is understood that in other embodiments, the vent hole 11c, the waterproof vent module 150 and the baffle 160 need not be disposed in the mounting groove 11b, for example, the vent hole 11c may extend to other positions on the circumferential side surface of the middle frame 111.

When the shell assembly 110 is applied to the wearable device 10, since the waterproof and breathable module 150 covers one side of the vent hole 11c facing away from the accommodating cavity 11a and the waterproof and breathable module 150 is covered by the baffle 160, the wearable device 10 can generate a trend of compressing the middle frame 111 by the waterproof and breathable module 150 when the wearable device 10 is in a waterproof test process or under the condition of water immersion, and water pressure acts on one side of the waterproof and breathable module 150 facing away from the accommodating cavity 11a, so that the waterproof and breathable module 150 can be prevented from loosening, and the working reliability of the waterproof and breathable module 150 can be guaranteed.

The baffle 160 is used to protect the waterproof and breathable module 150 so as to prevent the waterproof and breathable film 155 from being damaged due to the impact of foreign objects or contact with the waterproof and breathable module 150. The gap 11d between the baffle 160 and the waterproof and breathable module 150 can prevent the baffle 160 from directly generating a pressing force on the waterproof and breathable module 150, so as to protect the waterproof and breathable module 150. This arrangement may also promote authenticity of waterproof test results of the wearable device 10.

Specifically, with reference to fig. 12, in the waterproof test process of the wearable device 10, the water pipe 20 of the test device may be abutted to the baffle 160 and water of a certain pressure is injected into the water pipe 20, since the baffle 160 is fixedly connected to the middle frame 111 and the gap 11d exists between the baffle 160 and the waterproof and breathable module 150, the abutting pressure of the water pipe 20 to the baffle 160 is transmitted to the middle frame 111 instead of the waterproof and breathable module 150, so as to avoid that the waterproof and breathable module 150 is indirectly compressed by the water pipe 20 due to the abutting pressure of the water pipe 20, thereby reducing the authenticity of the waterproof test result. When water with a certain water pressure is introduced into the water pipe 20, the water enters the gap 11d through the through holes 160a of the baffle 160, and then contacts the waterproof and breathable module 150 and the middle frame 111. When the waterproof breathable film 155 is sealed poorly, water enters the accommodating cavity 11a through the vent hole 11c, so that a defective product is detected; when the waterproof breathable film 155 is well sealed, no water enters the housing cavity 11a through the vent hole 11 c. Therefore, in the whole waterproof test process, the waterproof breathable film 155 is not pressed by an external force due to the existence of the gap 11d, so that the real waterproof performance of the waterproof breathable film 155 can be detected.

Of course, the water pipe 20 can be pressed against the middle frame 111 during the waterproof test, and in this embodiment, the baffle 160 still can protect the waterproof and breathable module 150, and prevent the test equipment from accidentally pressing the baffle 160, which may reduce the authenticity of the waterproof test result.

Referring to fig. 6, in some embodiments, the middle frame 111 is provided with a receiving groove 11e at a side opposite to the receiving cavity 11a, and referring to fig. 10, the waterproof and breathable module 150 is installed in the receiving groove 11e, and the vent hole 11c is disposed at the bottom of the receiving groove 11 e. The receiving groove 11e facilitates the assembly and positioning of the waterproof and breathable module 150 on the middle frame 111, so as to improve the convenience of assembly. Further, referring to fig. 6 and fig. 10, a sinking groove 11f is disposed on a side of the middle frame 111 opposite to the accommodating cavity 11a, the accommodating groove 11e is opened at a bottom of the sinking groove 11f, the baffle 160 is mounted in the sinking groove 11f and covers the accommodating groove 11e, and the sinking groove 11f facilitates assembly and positioning of the baffle 160 on the middle frame 111, so as to improve convenience of assembly. A connecting member 170, such as a double-sided tape or a dispensing tape, may be disposed between the baffle 160 and the bottom wall 11g of the sinking groove 11f to form a secure connection between the baffle 160 and the middle frame 111. Of course, in other embodiments, the connector 170 is not required. For example, the baffle 160 may be welded to the middle frame 111.

Further, in some embodiments, the thickness of the waterproof air-permeable module 150 is smaller than the depth of the accommodating groove 11e, and this arrangement can ensure that a gap 11d is formed between the baffle 160 and the waterproof air-permeable module 150. In other embodiments, the thickness of the waterproof and air-permeable module 150 may be approximately equal to the depth of the accommodating groove 11e, and the connecting member 170 is disposed between the baffle 160 and the bottom wall 11g of the sinking groove 11f, so as to ensure that a gap 11d is formed between the baffle 160 and the waterproof and air-permeable module 150. Of course, in other embodiments, the baffle 160 may be screwed to the middle frame 111 or fixedly connected to the middle frame 111 by a snap structure.

Further, referring to fig. 6, the bottom wall 11g of the sinking groove 11f is disposed around the accommodating groove 11e, the connecting member 170 is disposed around the accommodating groove 11e and connected to the bottom wall 11g of the sinking groove 11f, and the baffle 160 covers the connecting member 170 and is fixedly connected to the middle frame 111 through the connecting member 170. In the embodiment where the connection member 170 is a double-sided tape or a dispensing tape, this arrangement may enable the middle frame 111 around the mounting groove 11b to form a reliable seal with the baffle 160, so as to improve the waterproof and dustproof performance of the electronic device 100. In this embodiment, the connector 170 forms a through hole 170a communicating with the through hole 160a, and the through hole 170a extends to a side of the connector 170 facing the waterproof and breathable module 150, so that air can flow through the through hole 160a and the through hole 170 a.

Further, in the present embodiment, the cross-sectional area of the through hole 170a is smaller than the cross-sectional area of the receiving groove 11e, so that the connecting member 170 covers at least a portion of the edge of the waterproof and breathable module 150, and this arrangement can further ensure the sealing performance between the baffle 160 and the middle frame 111. Further, the cross-sectional areas of the vent hole 11c and the through hole 160a may be smaller than the cross-sectional area of the through hole 170a, in other words, the through hole 170a and the portion of the gap 11d not filled by the connector 170 may form a cavity with a relatively large volume, and the cross-sectional area of the cavity is larger than the cross-sectional areas of the vent hole 11c and the through hole 160a, so that the cavity may buffer air, and air pressure balance between the inside and the outside of the electronic device 100 may be achieved.

Further, a side of the waterproof and air-permeable module 150 facing the baffle 160 may be spaced apart from the connection member 170. This kind of setting can avoid test equipment to transmit to waterproof ventilative module 150 to the support pressure of baffle 160 in waterproof test process equally to can guarantee the authenticity of waterproof test result. Of course, in other embodiments, the bottom wall 11g of the sink 11f need not be disposed around the accommodating groove 11 e. For example, the bottom wall 11g of the sink 11f may be provided at both ends in the longitudinal direction or both ends in the width direction of the rectangular accommodation groove 11 e. Sealant can be filled between the baffle 160 and the sidewall of the sinking groove 11f to improve the sealing performance between the baffle 160 and the middle frame 111. Further, when the baffle 160 is disposed in the sinking groove 11f, the side of the baffle 160 facing away from the waterproof and breathable module 150 may not protrude out of the bottom of the mounting groove 11b, in other words, the thickness of the baffle 160 or the combined thickness of the baffle 160 and the connecting member 170 may be less than or equal to the depth of the sinking groove 11f, so that when the baffle 160 is mounted in the sinking groove 11f, the side of the baffle 160 facing away from the waterproof and breathable module 150 is flush with the bottom of the mounting groove 11b or is recessed into the bottom of the mounting groove 11b, thereby preventing the baffle 160 from interfering with the strap assembly 200.

Of course, it will be understood that the sink 11f is not necessary. The bottom of the mounting groove 11b may have a planar area, the accommodating groove 11e is opened in the planar area, the planar area is disposed around the periphery of the accommodating groove 11e, and the baffle 160 covers the planar area.

Referring to fig. 13 and 14, in another embodiment, the sink 11f may be omitted. The baffle 160 may be fixedly connected to the waterproof and breathable module 150 by a connector 170.
