[0029] Referring to Figures 1 to 6 The present embodiments provide an electronic device 200, which can be a mobile phone, a tablet computer, a wearable device, etc. The electronic device 200 includes a middle frame housing 90 and a card holder 100. The middle frame housing 90 has a card slot 91 formed in a side portion thereof, and the card holder 100 is inserted into the card slot 91. The card holder 100 includes a card holder body 10 and a sealing ring 20. The card holder body 10 has a cap 11 at an end portion thereof, and a plurality of card holder slots 15 for loading a SIM card or a memory card are formed in the card holder body 10.

[0030] ​​The surface of the sealing ring 20 is formed with a sealing portion 21 arranged in the circumferential direction, which protrudes from the sealing ring 20 to the direction away from the card holder body 10. It can be understood that the circumferential direction of the sealing ring 20 is perpendicular to the insertion direction of the card holder body 10, and the projection of the sealing ring 20 on the projection plane perpendicular to the insertion direction of the card holder body 10 is surrounded by the outer periphery of the projection of the card holder body 10 on the projection plane.

[0031] The sealing portion 21 is provided with a pressure relief groove 22, which penetrates the sealing portion 21 along the insertion direction of the card holder body 10, and can form a pressure relief channel communicating with the inner cavity of the electronic device 200 after the card holder 100 is assembled to the electronic device 200, so as to realize the intercommunication of the air inside and outside the whole machine. Optionally, the projection shape of the pressure relief groove 22 on the projection plane perpendicular to the insertion direction of the card holder body 10 is trapezoidal, rectangular or track-shaped, and the shape, width and depth of the pressure relief groove 22 can be adjusted according to the actual project, which is not limited in the present disclosure.

[0032] The sealing portion 21 of the sealing ring 20 of the card holder 100 abuts against the inner wall of the card slot 91, and plays a sealing and waterproof effect. The card holder body 10 and the inner wall of the card slot 91 have a first gap 92, and the sealing ring 20 and the inner wall of the card slot 91 have a second gap 93, and the first gap 92 and the second gap 93 are communicated through the pressure relief groove 22 of each sealing ring 20 to form a pressure relief channel (as shown by the dotted line direction in FIG. 8). Figure 5 and Figure 6 The first gap 92 and the second gap 93 are communicated through the pressure relief groove 22 of each sealing ring 20 to form a pressure relief channel (as shown by the dotted line direction in FIG. 8), so as to balance the air pressure inside and outside the middle frame housing 90.

[0033] In the present embodiment, the part of the card holder body 10 for arranging the sealing ring 20 has a track-shaped cross section in the direction perpendicular to the insertion direction of the card holder body 10. In other examples, the cross section of the card holder body 10 in the direction perpendicular to the insertion direction of the card holder body 10 can also be rectangular or other structural shapes, which are not limited in the present disclosure.

[0034] The electronic device 200 of the present embodiment can form a pressure relief channel communicating with the inner cavity of the electronic device 200 by arranging the pressure relief groove 22 on the sealing portion 21 of the sealing ring 20 of the card holder 100, so as to realize the intercommunication of the air inside and outside the whole machine after the card holder 100 is assembled to the card slot 91 of the electronic device 200, ensure the air pressure balance inside and outside the whole machine to guarantee the acoustic performance, and avoid problems such as noise when the internal space of the whole machine changes (such as the reduction of the internal space under pressure). The pressure relief grooves 22 of the two adjacent sealing rings 20 of the card holder 100 are arranged on different sides of the card holder body 10, which can prolong the water inlet path and improve the waterproof effect. It is not necessary to additionally arrange a waterproof and breathable film, which reduces the auxiliary materials and saves the cost.

[0035] In some optional embodiments, there are at least two sealing rings 20, which are arranged on the card holder body 10 in the direction of insertion (X direction in the figure) of the card holder body 10. It can be understood that the direction of insertion of the card holder body 10 can be understood as the length direction of the card holder body 10. In this way, the length direction of the card holder body 10 is provided with multiple layers of sealing rings, which can improve the sealing effect.

[0036] The pressure relief grooves 22 of the two adjacent sealing rings 20 are arranged on different sides of the card holder body 10. It can be understood that in the direction of insertion of the card holder body 10, for example, the pressure relief groove 22 of the first sealing ring 20 is arranged on the upper part of the card holder body 10, the pressure relief groove 22 of the second sealing ring 20 is arranged on the lower part or the side part of the card holder body 10 except the upper part, and the pressure relief groove 22 of the third sealing ring 20 is arranged on the upper part or the side part of the card holder body 10 except the lower part or the side part. Other sealing rings are arranged in this way, which can prolong the water inlet path of the external water vapor entering the electronic device 200 into the inner cavity through the pressure relief groove 22, thereby improving the waterproof effect.

[0037] In some optional embodiments, the projections of the pressure relief grooves 22 of the two adjacent sealing rings 20 on the projection plane perpendicular to the direction of insertion of the card holder body 10 are symmetrically opposite to the center of the projection of the card holder body 10 on the projection plane. For example, the pressure relief groove 22 of the first sealing ring 20 is arranged on the left side of the upper part of the card holder body 10, the pressure relief groove 22 of the second sealing ring 20 is arranged on the right side of the lower part of the card holder body 10, and the pressure relief groove 22 of the third sealing ring 20 is arranged on the left side of the upper part of the card holder body 10. In this way, when the external water vapor enters the electronic device 200, the sealing part 21 of each sealing ring 20 can ensure good sealing and waterproof effect. After the water vapor passes through the pressure relief groove 22 of the first sealing ring 20 and reaches the sealing part 21 of the second sealing ring 20, it needs to flow around the sealing part 21 for a distance of half a circle to pass through the pressure relief groove 22 of the second sealing ring 20, thereby prolonging the water inlet path of the external water vapor entering the inner cavity of the electronic device 200 and improving the waterproof effect.

[0038] In the present embodiment, the number of sealing rings 20 is two, and the pressure relief grooves 22 of the two sealing rings 20 are arranged on opposite sides of the card holder body 10.
