[0025] In the specific embodiments, the various specific technical features and each embodiment described can be combined in any suitable manner without conflict. For example, different combinations of specific technical features / embodiments can form different embodiments. To avoid unnecessary repetition, the various possible combination methods of the specific technical features / embodiments in the present utility model will not be described separately.

[0026] The present utility model provides a card slot. Please refer to Figures 1 to 5, the card tray 100 includes a card tray body 10 and a waterproof sealing ring 20. The card tray body 10 includes a door panel 11, a connecting member 12, and a tray body 13. One end of the connecting member 12 is connected to the door panel 11, and the other end of the connecting member 12 is connected to the tray body 13. A sealing ring groove 121 is provided on the outer peripheral side of the connecting member 12. The waterproof sealing ring 20 is sleeved in the sealing ring groove 121. An annular convex peak 21 is integrally provided on the outer peripheral side of the waterproof sealing ring 20. A relief ring groove 22 is provided on the first side and / or the second side of the annular convex peak 21. Herein, the first side is the side of the annular convex peak 21 close to the connecting member 12, and the second side is the side of the annular convex peak 21 close to the tray body 13. When the card tray 100 is inserted into and removed from the electronic device, the annular convex peak 21 may be squeezed by the electronic device. The provision of the relief ring groove 22 enables the annular convex peak 21 to have sufficient movement space, avoiding excessive extrusion of the waterproof sealing ring 20, and to a certain extent, relieving the stress concentration of the waterproof sealing ring 20. Therefore, on the basis of ensuring the sealing effect, the present utility model reduces the damage risk of the waterproof sealing ring 20 and increases the service life of the waterproof sealing ring 20.

[0027] It can be understood that currently, high-end mobile phones and electronic devices such as children's smart phone watches generally have high-level waterproof requirements (IPX8). The design of waterproof features is particularly important and crucial. Waterproof performance and insertion and removal life are important indicators for evaluating waterproof products. The card tray 100 provided by the present utility model is convenient to operate, has a high waterproof level, and a long insertion and removal life, meeting the current development requirements of the industry. In actual use, the insertion and removal life of the present utility model is not less than 5000 times.

[0028] Regarding the door panel 11, since the card trays applied to digital devices such as mobile phones and phone watches in the current market are generally ejected by using a card ejection pin through the pushing rod of the card tray, but because the card pin is too small and easy to lose, and its use and operation also have certain limitations, the requirements for personnel and tools are fixed. Especially children and the elderly are not used to or difficult to operate the card ejection with a card pin, resulting in inconvenient use. Therefore, please refer to Figure 2 , optionally, the side of the door panel 11 close to the connecting member 12 may have a hand-holding groove 111. The user can directly pull out the card tray 100 from the electronic device through the hand-holding groove 111 without using a card pin, which is convenient for taking out the card and has strong practicability.

[0029] In specific applications, the hand-holding groove 111 may be provided on two opposite sides of the door panel 11 (along the thickness direction of the door panel 11), which is more convenient for the user to operate.

[0030] Specifically, the hand-holding groove 111 may penetrate the side of the door panel 11 close to the connecting member 12, so that the user's finger has sufficient space to tightly hold the hand-holding groove 111.

[0031] Specifically, the height of the bottom surface of the hand-holding groove 111 can be lower than the height of the connecting member 12 (in the thickness direction of the card holder 100), and the depth of the bottom surface of the hand-holding groove 111 penetrating through the door panel 11 is relatively deep, so as to further increase the hand-holding space of the hand-holding groove 111.

[0032] Specifically, the front side wall of the hand-holding groove 111 (the side wall away from the connecting member 12) and the bottom surface of the hand-holding groove 111 can form an obtuse angle, so as to further increase the hand-holding space of the hand-holding groove 111.

[0033] For the connecting member 12, please refer to Figure 2 , optionally, the vertical cross-section of the connecting member 12 can be in the shape of a "work" character. Correspondingly, the sealing ring groove 121 can be a rectangular ring groove, that is, the openings of the sealing ring groove 121 on the connecting member 12 are all rectangular, which is convenient for processing, and the two sides of the connecting member 12 can effectively fix the waterproof sealing ring 20.

[0034] Optionally, the connecting member 12 is provided with a first guiding structure 122 on one side of the sealing ring groove 121 close to the holder body 13; the connecting member 12 is provided with a second guiding structure 123 on the other side of the sealing ring groove 121 away from the holder body 13. When the waterproof sealing ring mold sets the waterproof sealing ring 20 in the sealing ring groove 121, the first guiding structure 122 and the second guiding structure 123 play a guiding role for the mold, avoiding scratching the connecting member 12 by the waterproof sealing ring mold, and also avoiding the debris generated by scratching the connecting member 12 from mixing into the uncured waterproof sealing ring 20 and causing the waterproof sealing ring 20 to fail.

[0035] Specifically, the first guiding structure 122 can be a first inclined surface and a second inclined surface provided on the outer peripheral side of the connecting member 12 and connected; the second guiding structure 123 can be a third inclined surface and a fourth inclined surface provided on the outer peripheral side of the connecting member 12 and connected. The waterproof sealing ring mold can be provided with corresponding inclined surfaces, so as to play a guiding role for the waterproof sealing ring 20 mold. Of course, the specific structures of the first guiding structure 122 and the second guiding structure 123 are not limited to this, and can also be guiding blocks or guiding grooves, etc., as long as they can play a guiding role.

[0036] Optionally, at least one groove 124 or concave hole 125 is provided on the bottom surface of the sealing ring groove 121, and by using the glue pulling effect of the uncured waterproof sealing ring 20, the adhesion between the waterproof sealing ring 20 and the bottom surface of the sealing ring groove 121 is enhanced, and the connection firmness is increased.

[0037] For the holder body 13, please refer to Figure 2, preferably, the supporting body 13 may include a one-piece card slot body 131 and a metal sheet 132 embedded in the card slot body 131. The card slot body 131 is made of plastic material. The supporting body 13 can be formed by inlaying and injecting the metal sheet 132 and the card slot body 131. The metal sheet 132 is made of steel, and the steel has high strength. The metal sheet 132 can be connected with a metal strip made by one-time stamping. The metal strip can be clamped and positioned by an injection mold (the mold for forming the card slot body 131). After the card slot body 131 is formed, the metal strip can be cut off, and only the metal sheet 132 embedded in the card slot body 131 is retained, which is convenient for processing.

[0038] For the waterproof sealing ring 20, please refer to Figure 3 and Figure 4 , optionally, both side surfaces of the annular convex peak 21 (the two surfaces facing the door panel 11 or the supporting body 13) can be inclined surfaces, so that when the user inserts and removes the card tray 100, the inclined surfaces play a role of smooth transition, further increasing the service life of the waterproof sealing ring 20. And, preferably, the annular convex peak 21 does not have sharp corners, that is, the upper end of the annular convex peak 21 (the middle connection of the two inclined surfaces on both sides of the annular convex peak 21) can be an arc surface, and / or the two sides of the upper end are rounded corners, so that when the card tray 100 is inserted and removed, the transition is smoother, avoiding scratching the electronic device, etc. Specifically, the vertical cross-section of the annular convex peak 21 can be approximately an isosceles trapezoid or an inverted "V" shape, etc.

[0039] Optionally, a sealing transition structure 23 can be provided between the groove side walls of the relief ring groove 22 and the sealing ring groove 121. The sealing transition structure 23 not only ensures the waterproof sealing effect of the waterproof sealing ring 20, but also plays a transition role for the groove side walls of the relief ring groove 22 and the sealing ring groove 121, avoiding the direct connection of the relief ring groove 22 to the groove side wall, with a smooth connection, avoiding affecting the waterproof sealing effect, and also reducing the damage to the waterproof sealing ring 20 when the card tray 100 is inserted and removed, increasing the service life of the waterproof sealing ring 20. Specifically, the sealing transition structure 23 can be a transition surface on the waterproof sealing ring 20 parallel to the groove side wall of the sealing ring groove 121 (along the direction perpendicular to the door panel 11 to the connecting member 12, the transition surface is parallel to the wall surface on one side of the sealing ring groove 121), can be a plane slightly higher than the groove side wall of the sealing ring groove 121, or can be an inclined surface or an arc surface connecting the relief ring groove 22 and the groove side wall, etc.

[0040] Specifically, the waterproof sealing ring 20 can be a silicone part or a TPU (thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber) part, and can be injection molded with liquid silicone or TPU during preparation, which is convenient for preparation. Further, the hardness of the waterproof sealing ring 20 can be 40 to 70 degrees.

[0041] During production, the card slot body 131 and the metal sheet 132 can be formed in one step; then the metal sheet 132 strip is cut; then the door panel 11, the connecting piece 12 and the support body 13 are injection-molded into an integrated structure to form the card holder body 10; after the integrated injection molding is completed, the door panel 11 is subjected to spraying or vacuum plating process; finally, liquid silicone or TPU is injection-molded to make the waterproof sealing ring 20 disposed on the sealing ring groove 121 of the connecting piece 12, forming the card holder 100; after that, the finished product inspection of the card holder 100 can also be carried out.

[0042] The present invention also provides an electronic device. Please refer to Figure 5 , the electronic device includes a device body 200 and the card holder 100 as described above. The device body 200 has a mounting groove for mounting the card holder 100, which is convenient for users to use.

[0043] Optionally, the device body 200 is provided with an insertion groove 210 on one side of the mounting groove for the user's finger to extend into. The insertion groove 210 can correspond to the hand-held groove 111, so as to facilitate the user to reach into the hand-held groove 111 to take out the card holder 100.

[0044] The present invention provides a card holder and an electronic device. The card holder 100 includes a card holder body 10 and a waterproof sealing ring 20. The card holder body 10 includes a door panel 11, a connecting piece 12 and a support body 13. One end of the connecting piece 12 is connected to the door panel 11, and the other end of the connecting piece 12 is connected to the support body 13. A sealing ring groove 121 is provided on the outer peripheral side of the connecting piece 12. The waterproof sealing ring 20 is sleeved on the sealing ring groove 121. An annular convex peak 21 is integrally provided on the outer peripheral side of the waterproof sealing ring 20. A relief ring groove 22 is provided on the first side and / or the second side of the annular convex peak 21. When the card holder 100 is inserted and removed, the annular convex peak 21 may be squeezed by the electronic device, but the setting of the relief ring groove 22 enables the annular convex peak 21 to have sufficient movement space, avoiding excessive extrusion of the waterproof sealing ring 20, and to a certain extent, relieving the stress concentration of the waterproof sealing ring 20. Therefore, on the basis of ensuring the sealing effect, the present invention reduces the damage risk of the waterproof sealing ring 20 and increases the durability life of the waterproof sealing ring 20.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
