These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0050] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0051] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0053] like Figure 1 As shown, in the related art, the housing 101 of the smart watch is provided with a receiving cavity 102 with an opening, a SIM card holder 103 is arranged in the receiving cavity 102, a SIM card 105 is installed in the SIM card holder 103, and a card cover 104 is covered in the receiving cavity 102 to prevent the SIM card 105 from falling. The housing 101 is also provided with an opening connected to the receiving cavity 102, and the opening is used for a prying tool 106 to extend into. When the user uses the prying tool 106 to extend from the opening into the receiving cavity 102 to pry the card cover 104, the prying tool 106 is in an inclined state relative to the surface of the housing 101 facing the card cover 104, that is, the force of the prying tool 106 on the card cover 104 is an inclined force, and after the prying tool 106 pries the card cover 104 open, the prying tool 106 will continue to move in an inclined state under the action of inertia, thereby causing the prying tool 106 to move into the SIM card holder 103 (such as Figure 1 The prying tool shown by the dotted line in the middle) may cause the prying tool to damage the SIM card holder 103.

[0054] Based on this, the present application provides a shell structure, a smart host and a smart wearable device, wherein the shell structure can effectively prevent the prying tool from moving toward the card holder, thereby avoiding damage to the card holder.

[0055] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0056] Embodiment 1

[0057] Please also read Figures 2 to 5 The first embodiment of the present invention discloses a shell structure 1, which is a shell structure 1 of a smart host. The smart host can be applied to a smart wearable device and used as a host of the smart wearable device. The smart wearable device may include but is not limited to a smart watch, a smart bracelet, etc. Taking a smart watch as an example, the smart host can be used as the host part of the smart watch, and the shell structure 1 is the shell of the host part, that is, the shell structure 1 can be used as the shell of the smart host. Specifically, the shell structure 1 includes a shell 11 and a card cover 12. The shell 11 is provided with a accommodating cavity 1a having a first opening 1b and a resisting portion 111 located outside the accommodating cavity 1a. The accommodating cavity 1a is used to set a card holder 2 for installing a card. The card cover 12 is detachably connected to the shell 11 to cover the first opening 1b of the accommodating cavity 1a. A finger-picking groove 1d having a second opening 1c is formed between the card cover 12 and the shell 11. The resisting portion 111 is used to resist the prying tool 20 when the prying tool 20 extends into the finger-picking groove 1d from the second opening 1c to prevent the prying tool 20 from contacting the card holder 2.

[0058] The housing structure 1 of the first embodiment of the present invention comprises a housing 11 and a card cover 12 disposed on the housing 11, and the housing 11 further comprises a receiving cavity 1a for arranging the card holder 2, the receiving cavity 1a can be used to install the card so as to achieve abutment between the card and the card holder 2, and a gripping groove 1d having a second opening 1c is formed between the card cover 12 and the housing 11, so that a prying tool 20 (such as Figure 5 The housing 11 is provided with a resisting portion 111, when the prying tool 20 extends from the second opening 1c to the finger groove 1d to pry the card cover 12, if the prying tool 20 continues to move toward the accommodating chamber 1a under the action of inertia after prying the card cover 12, the prying tool 20 will abut against the resisting portion 111, and will not move into the accommodating chamber 1a, which can effectively prevent the prying tool 20 from damaging the card holder 2 in the accommodating chamber 1a, resulting in damage to the card holder 2. Therefore, the smart host 10 with the housing structure 1 can effectively protect the card holder 2 in the accommodating chamber 1a from being pried off, which is beneficial to improving the service life of the card holder 2.

[0059] It should be noted that the card installed in the card holder 2 can be a SIM card with communication function, a memory card (SD card, TF card) for data storage function, etc. The type of card installed in the card holder 2 is not limited in this embodiment. Exemplarily, the card holder 2 is used to install a SIM card, so that the user can replace the SIM card conveniently.

[0060] It should also be noted that the pry tool 20 can be any tool for prying the card cover 12 . For example, the pry tool 20 can be a tool with a plate-like structure. Of course, when the user uses fingernails to pry the card cover 12 , the fingernails can also be regarded as the pry tool 20 .

[0061] In some embodiments, the resisting portion 111 is located on the side of the finger groove 1d away from the second opening 1c. Since the resisting portion 111 is located on the side of the finger groove 1d away from the second opening 1c, when the prying tool 20 extends from the second opening 1c into the finger groove 1d, the resisting portion 111 is located in the extension direction of the prying tool 20. In other words, if the prying tool 20 pries open the card cover 12 and continues to move forward under the action of inertia, the resisting portion 111 is located in the direction in which the prying tool 20 continues to move forward under the action of inertia, so that it can directly abut against the prying tool 20 that continues to move forward under the action of inertia, so as to prevent the prying tool 20 from extending into the accommodating cavity 1a and damaging the card holder 2.

[0062] Optionally, the surface of the housing 11 facing the card cover 12, the surface of the card cover 12 facing the housing 11, and the surface of the blocking portion 111 facing the second opening 1c jointly form a hand-picking groove 1d. The housing 11, the card cover 12, and the blocking portion 111 jointly form the hand-picking groove 1d, and in particular, the blocking portion 111 forms a part of the hand-picking groove 1d, so that the layout of the housing structure 1 is more reasonable, which is conducive to realizing the miniaturized design of the housing structure 1.

[0063] Specifically, a tongue 12a is provided on one side of the card cover 12, and the stopper 111 can be a protruding stopper protruding from the housing 11 toward the card cover 12 and is provided corresponding to the tongue 12a, and the stopper 111, the surface of the tongue 12a facing the housing 11, and the surface of the housing 11 facing the tongue 12a together form a finger-picking groove 1d. In other words, the finger-picking groove 1d is located on one side of the card cover 12, so that the other side of the card cover 12 can be detachably connected to the accommodating cavity 1a, and the tongue 12a can be used for prying by the prying tool 20, which ensures the reliability of the connection between the card cover 12 and the accommodating cavity 1a while making the card cover 12 easy to pry.

[0064] In the related art, in order to facilitate the identification of the closing direction of the card cover 12 to ensure the installation position of the card, the card cover 12 is often designed with a cut corner (i.e., to achieve foolproofing). However, such a card cover 12 has poor consistency in appearance and is relatively complex in design. In the present solution, since a tongue 12a is provided on one side of the card cover 12 and a stopper 111 is provided on the housing 11 at a position corresponding to the tongue 12a, the tongue 12a of the card cover 12 and the stopper 111 of the housing 11 can both be used as foolproofing designs to ensure the correct closing direction of the card cover 12.

[0065] Furthermore, the side of the card cover 12 away from the accommodating cavity 1a can be designed as an axisymmetric structure (eg Figure 3 As shown, the card cover 12 is symmetrical with respect to the symmetry axis o on the side away from the accommodating cavity 1a. In other words, the card cover 12 does not need to be cut corners, thereby ensuring the appearance consistency of the card cover 12 structure.

[0066] It is understandable that, since there are multiple components disposed inside the smart host 10, such as the card holder 2, PPG (photoplethysmograph), etc., and the length or width of these components is smaller than the length or width of the smart host 10, when these components are disposed inside the housing 11 of the smart host 10, part of the space inside the housing 11 will be vacant, which not only makes the volume of the smart host 10 larger but also part of the volume is not effectively utilized. Based on this, in some embodiments, the housing 11 is provided with a protruding annular structure 13, the annular structure 13 is provided with a receiving cavity 1a, and a hand-gripping groove 1d with a second opening 1c is formed between the side wall of the annular structure 13 and the card cover 12. By providing a protruding annular structure 13 on the shell 11 and providing an accommodating cavity 1a in the annular structure 13, the card holder 2 or other components can be arranged in the annular structure 13, that is, the card holder 2 or other components only occupy the volume of the annular structure 13, which can avoid the situation where the volume of the shell 11 is vacant, which is conducive to realizing the small design of the shell 11, and thus conducive to realizing the miniaturized design of the smart host 10, so as to improve the user's wearing experience.

[0067] In addition, since a hand-picking groove 1d with a second opening 1c is formed between the side wall of the protruding annular structure 13 and the card cover 12, that is, the hand-picking groove 1d is formed on the side of the protruding annular structure 13, the structure of the shell 11 itself is fully utilized to form the hand-picking groove 1d, thereby simplifying the structure of the shell 11 and making the processing technology of the shell 11 simpler. For example, a part of the material of the side wall of the protruding annular structure 13 can be cut off or a notch can be formed at the side wall of the protruding annular structure 13 when manufacturing the shell 11, so that a hand-picking groove 1d with a second opening 1c can be formed between the side wall of the protruding annular structure 13 and the card cover 12, and a second opening 1c can be formed between the side wall of the shell 11 and the card cover 12.

[0068] It is understandable that, combined with Figure 6 As shown, in other embodiments, the shell structure 1 may not be provided with the protruding annular structure 13. Then, in order to simplify the structure of the shell 11 and make the processing technology of the shell simpler, the card seat 2 may be arranged at a position close to the edge of the shell 11, so as to form a hand-picking groove 1d between the side wall of the shell 11 and the card cover 12. In this way, the structure of the shell 11 itself is fully utilized to form the hand-picking groove 1d, thereby simplifying the structure of the shell 11 and making the processing technology of the shell simpler. For example, when processing the shell structure 1, it is only necessary to remove part of the material of the side wall of the shell 11, or to form a notch at the side wall of the accommodating cavity 1a of the shell 11 when the shell 11 is formed, so that a second opening 1c is formed between the side wall of the shell 11 and the card cover 12.

[0069] Please also read Figure 4and Figure 5 As shown, optionally, the outer ring side wall of the annular structure 13 is formed as a support portion 14, and the support portion 14 is located on one side of the blocking portion 111, and a finger groove 1d is formed between the support portion 14 and the card cover 12. By providing the support portion 14, the prying tool 20 can abut against the support portion 14 when extending into the finger groove 1d, so as to pry the card cover 12 with the support portion 14 as a fulcrum, so that it is more convenient for the user to apply force to the prying tool 20 to pry the card cover 12. Specifically, the support portion 14 can be a convex block, so as to support the prying tool 20.

[0070] Furthermore, the support portion 14 is arranged corresponding to the edge of the card cover 12, and the support portion 14 has a support surface 143 facing the card cover 12, and a second opening 1c is formed between the support surface 143 and the edge of the card cover 12. Since the support portion 14 is arranged corresponding to the edge of the card cover 12, when the prying tool 20 extends to the second opening 1c position of the finger groove 1d, it can abut against the support surface 143 of the support portion 14. At this time, the user can use force on the prying tool 20 to pry open the card cover 12. In this way, the length of the prying tool 20 extending into the finger groove 1d can be shorter, which not only makes it easier to pry the card cover 12, but also makes it difficult to extend into the accommodating cavity 1a, so as to avoid damaging the card holder 2 in the accommodating cavity 1a.

[0071] It is understandable that, since a child user may insert foreign objects into the second opening 1c during use, the foreign objects may enter the hand-picking groove 1d from the second opening 1c. Based on this, in some embodiments, the vertical distance H between the support surface and the surface of the card cover 12 facing the support surface is 0.7mm-0.8mm. For example, the vertical distance between the support surface and the surface of the card cover 12 facing the support surface is 0.7mm, 0.73mm, 0.75mm, 0.78mm, 0.8mm, etc. By setting the distance between the support surface and the card cover 12 to 0.7mm-0.8mm, that is, the opening height of the second opening 1c is 0.7mm-0.8mm, it can not only ensure that the prying tool 20 can extend from the second opening 1c to the hand-picking groove 1d to pry open the card cover 12, but also, because the opening height of the second opening 1c is very small, it can prevent some foreign objects from entering the hand-picking groove 1d from the second opening 1c, and also prevent foreign objects from blocking the second opening 1c.

[0072] In some embodiments, a recessed portion 141 is provided between the support portion 14 and the resisting portion 111, and the recessed portion 141 forms a part of the finger-picking groove 1d. Since the recessed portion 141 is provided between the support portion 14 and the resisting portion 111, the space of the finger-picking groove 1d can be increased, so that the prying tool 20 can be inserted into the finger-picking groove 1d from the second opening 1c, thereby facilitating the prying of the card cover 12.

[0073] Furthermore, the support portion 14 has a first inclined surface 142 extending to the recessed portion 141, and the first inclined surface 142 is used to gradually increase the opening of the recessed portion 141 from the support portion 14 to the direction of the blocking portion 111. In this way, the space of the recessed portion 141 is relatively large, and when the prying tool 20 is inserted into the finger groove 1d, the first inclined surface 142 can play a guiding role, so that the prying tool 20 can be inserted into the finger groove 1d in the direction of the first inclined surface 142 to facilitate prying the card cover 12.

[0074] In some embodiments, the support portion 14 is a protrusion protruding from the surface of the housing 11 of the housing 11, the distance between the housing surface 1e and the support surface 143 of the support portion 14 is L1, the distance between the bottom surface of the recessed portion 141 and the support surface 143 is L2, and L1>L2. In this way, there is a large distance between the support portion 14 and the surface of the housing 11, so that an escape portion can be formed. When the user uses the fingernail of the finger to pry the card cover 12, the escape portion can escape the finger that has not been inserted into the finger-picking groove 1d.

[0075] Optionally, a transition structure 15 is provided between the shell surface 1e and the support surface 143, and the transition structure 15 is a transition slope or a transition arc surface. By providing a transition slope or a transition arc surface between the shell surface 1e and the support surface 143, the shell 11 has a stronger structural strength than a vertical surface, and no sharp corners are formed between the support surface 143 and the shell surface 1e, which is convenient for the user to pry the card cover 12 with fingers.

[0076] In some embodiments, the card cover 12 is provided with an abutting portion 121 corresponding to the supporting portion 14, and the abutting portion 121 is used to abut against the prying tool 20 when the prying tool 20 extends into the finger-picking groove 1d. By the abutting portion 121 abutting against the prying tool 20, the force of the prying tool 20 in the direction of the accommodating cavity 1a can be changed, so that the prying tool 20 applies more force to the abutting portion 121 of the card cover 12, which is not only easier to pry up the card cover 12, but also less likely to move toward the accommodating cavity 1a under the action of inertia and cause damage to the card seat 2 in the accommodating cavity 1a. In addition, since the abutting portion 121 of the card cover 12 corresponds to the supporting portion 14, when the prying tool 20 extends from the second opening 1c into the finger-picking groove 1d, the card cover 12 can be pried with the supporting portion 14 or the abutting portion 121 as a fulcrum, so that the user can have multiple selectable prying directions for the convenience of the user.

[0077] Specifically, the abutting portion 121 includes a first surface 1211 and a second surface 1212 facing the supporting portion 14, the first surface 1211 is parallel to the supporting surface of the supporting portion 14, the second surface 1212 is connected to the first surface 1211 and is located on a side of the first surface 1211 close to the blocking portion 111, and the second surface 1212 is inclined from the connection with the first surface 1211 toward the blocking portion 111. The first surface 1211 and the second surface 1212 abut against the surface of the prying tool 20, the first surface 1211 provides a fulcrum for the prying tool 20 to pry the card cover 12, and the second surface 1212 can effectively prevent the prying tool 20 from moving toward the accommodating cavity 1a, thereby preventing the prying tool 20 from damaging the card holder 2 in the accommodating cavity 1a.

[0078] In some embodiments, a first water retaining protrusion 122 is provided on one side of the card cover 12 facing the housing 11, and the first water retaining protrusion 122 is located on the side of the blocking portion 111 facing away from the second opening 1c. When the card cover 12 is sealed on the first opening 1b of the accommodating chamber 1a, at least part of the first water retaining protrusion 122 extends into the accommodating chamber 1a. By providing the first water retaining protrusion 122, liquid can be prevented from entering the accommodating chamber 1a, so as to avoid failure of components such as electronic devices (such as the card holder 2) in the accommodating chamber 1a.

[0079] Furthermore, a second water retaining protrusion 123 is further provided on one side of the card cover 12 facing the housing 11, and the second water retaining protrusion 123 is located between the first water retaining protrusion 122 and the stopper 111, and a step portion 16 is formed between the outer periphery of the accommodating cavity 1a and the stopper 111, and the second water retaining protrusion 123 is used to abut against the step portion 16. Since the second water retaining protrusion 123 abuts against the step portion 16, when liquid enters the finger-picking groove 1d from the second opening 1c, it can effectively prevent the liquid from entering the accommodating cavity 1a from between the second water retaining protrusion 123 and the step portion 16. Specifically, if the smart host 10 is immersed in liquid, the liquid first needs to pass through the resisting portion 111, then through the second water retaining protrusion 123 and the step portion 16, and finally through the first water retaining protrusion 122 before it can enter the accommodating chamber 1a. It can be seen that a tortuous waterproof path is formed by the coordinated design of the first water retaining protrusion 122, the second water retaining protrusion 123 and the step portion 16, so that the path for the liquid to enter the accommodating chamber 1a is very tortuous and difficult to enter the accommodating chamber 1a. Therefore, a better waterproof effect can be achieved to avoid the situation where the liquid enters the accommodating chamber 1a from the finger groove 1d, causing the electronic components in the accommodating chamber 1a to fail. In addition, by abutting the second water retaining protrusion 123 against the step portion 16, the covering position of the card cover 12 can be limited, limiting the card cover 12 from extending too far into the accommodating cavity 1a, so as to reasonably set the force of the card cover 12 to press the card onto the card holder 2, thereby ensuring that the card can be electrically connected to the card holder 2 without reducing the life of the card holder 2 or the card due to overpressure.

[0080] Further, the surface of the second water retaining convex portion 123 facing the step portion 16 is provided with a protrusion 1231, and the area of ​​the surface of the protrusion 1231 facing the step portion 16 is smaller than the area of ​​the surface of the second water retaining convex portion 123 facing the step portion 16, and the protrusion 1231 abuts against the step portion 16. By providing the protrusion 1231 with a smaller surface area on the second water retaining convex portion 123, the protrusion 1231 abuts against the step portion 16, thereby reducing the abutment area between the protrusion 1231 and the step portion 16, and achieving a better waterproof effect. Exemplarily, the protrusion 1231 can be convex ball-shaped or convex strip-shaped, so that the surface of the protrusion 1231 abutting against the surface of the step portion 16 is smaller, so that the abutment between the second water retaining convex portion 123 and the step portion is tighter, and the waterproof performance is effectively improved.

[0081] Furthermore, the second water retaining protrusion 123 is spaced apart from the first water retaining protrusion 122, and the housing structure 1 further comprises a waterproof member 17, which is sealed and connected between the card cover 12 and the housing 11, and the waterproof member 17 abuts against the first water retaining protrusion 122 and the second water retaining protrusion 123. By providing the waterproof member 17 and the waterproof member 17 being sealed and connected between the card cover 12 and the housing 11 and abutting against the first water retaining protrusion 122 and the second water retaining protrusion 123, liquid can be further prevented from entering the accommodating cavity 1a.

[0082] Please also read Figure 7 and Figure 8 Optionally, the first water retaining protrusion 122 is a protruding ring arranged on the card cover 12, and the waterproof member 17 is a waterproof sleeve, and the waterproof member 17 is sleeved on the protruding ring so that the outer periphery of the waterproof member 17 abuts against the second water retaining protrusion 123 and the first water retaining protrusion 122. By means of the waterproof member 17 sleeved on the protruding ring, the waterproof member 17 has a larger abutting area with the first water retaining protrusion 122 and the second water retaining protrusion 123, thereby having a better sealing effect.

[0083] Optionally, the waterproof member 17 sleeved on the convex ring forms a receiving cavity 17a, the opening of the receiving cavity 17a is arranged toward the receiving cavity 1a for receiving at least part of the card, and the inner wall surface of the receiving cavity 17a is provided with a clamping protrusion 171, and the clamping protrusion 171 is used to limit the position of the card in the receiving cavity 17a. Since the waterproof member 17 forms the receiving cavity 17a and the inner wall surface of the receiving cavity 17a is provided with a clamping protrusion 171, when installing the card, the card can be first placed in the receiving cavity 17a and the clamping protrusion 171 is used to achieve the limiting effect, and then the card cover 12 is sealed in the receiving cavity 1a of the housing 11, so that the card is located in the receiving cavity 1a and abuts against the card seat 2. In this way, since the card cover 12 is movable, the installation of the card is more flexible. In addition, since the waterproof member 17 is provided with a clamping protrusion 171 to limit the card, it is not necessary to set a limiting component in the housing 11, which is conducive to reducing the volume of the housing 11 to achieve a miniaturized design.

[0084] It is understandable that the waterproof member 17 can be made of soft glue, such as rubber, silicone, etc., so as to achieve a better waterproof effect. The card cover 12 can be made of hard plastic to achieve a supporting effect. When the card cover 12 covers the accommodating cavity 1a, the waterproof member 17 sleeved on the card cover 12 abuts against the side of the card facing the card cover 12. The waterproof member 17 with a smaller hardness has a smaller pressing force on the card, which may cause the problem of insufficient pressing force between the card and the card holder 2. Based on this, in some embodiments, the card cover 12 is provided with a pressing portion 124 protruding toward the accommodating cavity 1a, and the waterproof member 17 is provided with an avoidance hole 17b corresponding to the pressing portion 124. The avoidance hole 17b is used to avoid the pressing portion 124 so that the pressing portion 124 is pressed against the card. In this way, the card can be pressed against the card holder 2 by the pressing portion 124 provided on the card cover 12, thereby improving the firmness of the abutment between the card and the card holder 2 to ensure the stability of the electrical connection of the card.

[0085] Specifically, the pressing portion 124 may be a convex column disposed on the card cover 12 . The pressing force between the card and the card holder 2 can be increased by pressing the convex column against the card, so as to ensure the stability of the electrical connection between the card and the card holder 2 .

[0086] Furthermore, the clamping part 124 can be set to be multiple, for example, the clamping part 124 can be set to 2, 3, 4, 5, etc. Exemplarily, the clamping part 124 is set to 4, and the 4 clamping parts 124 are evenly distributed on the card cover 12, thereby not only improving the clamping effect of the clamping part 124 on the card, but also making the clamping force between the card and the card holder 2 more uniform, so as to improve the stability of the electrical connection between the card and the card holder 2.

[0087] Optionally, there are multiple ways to form the boss on the card cover 12. To simplify the processing flow, the boss can be formed when the card cover 12 is injection molded, that is, the boss and the card cover 12 are formed into an integral structure. Therefore, only one injection molding process is required to form the card cover 12 with the boss.

[0088] Please refer again Figure 4 and Figure 5 In some embodiments, the card cover 12 is provided with an avoidance groove 125 at a position corresponding to the resisting portion 111, and at least part of the resisting portion 111 extends into the avoidance groove 125. By providing the avoidance groove 125 at a position corresponding to the resisting portion 111 of the card cover 12, the resisting portion 111 can be avoided, and the second opening 1c formed between the card cover 12 and the housing 11 can be set smaller to prevent foreign matter from entering the hand-picking groove 1d from the second opening 1c. In addition, since the resisting portion 111 extends into the avoidance groove 125, a waterproof path with a curved structure is formed between the resisting portion 111 and the avoidance groove 125, thereby improving the waterproof effect.

[0089] In some embodiments, the housing structure 1 includes a support member 18, which is disposed in the housing 11 and at least partially located in the accommodating cavity 1a to support the card holder 2. The housing 11 is provided with a positioning groove 112 connected to the accommodating cavity 1a, and at least part of the support member 18 is connected to the inner wall surface of the positioning groove 112. By providing the positioning groove 112 in the housing 11 and extending the support member 18 into the positioning groove 112 of the housing 11 to be fixedly connected to the inner wall surface of the positioning groove 112, the positioning accuracy of the support member 18 is improved.

[0090] Optionally, the support member 18 includes a support portion 181 and a fixing portion 182. When the support member 18 is installed on the housing 11, the support portion 14 is located in the accommodating cavity 1a, and the fixing portion 182 is located in the positioning groove 112 and fixedly connected to the groove wall of the positioning groove 112. In this way, the support portion 181 can support the card holder 2, and the fixing portion can be firmly fixed to the positioning groove 112. Specifically, the fixing portion 182 can be fixed to the positioning groove 112 by dispensing glue.

[0091] Furthermore, the supporting portion 181 may be a plate-like structure, and the fixing portion 182 is a convex edge protruding 1231 from the edge of the plate-like supporting portion 181. The fixing portion 182 extends into the positioning groove 112 and is fixed to the positioning groove 112, thereby improving the fixing reliability and positioning accuracy of the fixing portion.

[0092] Furthermore, the positioning groove 112 includes a first groove body 1121 and a second groove body 1122 connected to the first groove body 1121. The depth of the first groove body 1121 is greater than the depth of the second groove body 1122. The first groove body 1121 is used for the fixing part to extend therein, and part of the supporting part 181 is located in the second groove body 1122 and fixed to the second groove body 1122. By setting a stepped positioning groove 112, the firmness of the fixation of the support member 18 is further improved, thereby ensuring the positioning accuracy of the support member 18.

[0093] The housing structure 1 of the first embodiment of the present invention abuts against the prying tool 20 through the abutting portion 111, thereby preventing the prying tool 20 from extending into the accommodating cavity 1a under the action of inertia and causing damage to the card holder 2, which is beneficial to improving the service life of the card holder 2. In addition, by providing the supporting portion 14 for supporting the prying tool 20, it is convenient for the user to apply force to the prying tool 20 to pry open the card cover 12.
