Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more specifically, to a connection device and an electronic device. Background Technology

[0002] Memory cards are widely used in various electronic devices as storage devices. During use, memory cards are typically inserted into electronic devices via a card ejector mechanism. However, most memory card ejector mechanisms are cumbersome to operate, lacking automated ejection functionality. Furthermore, the locking mechanism usually directly latches onto the memory card to secure it. This makes manually removing the memory card from the ejector mechanism inconvenient and can easily damage the locking mechanism during the process. Utility Model Content

[0003] This application provides a connection device and an electronic device to solve at least one of the above-mentioned technical problems.

[0004] The connecting device according to an embodiment of this application is used for connecting a card-type electronic device, the connecting device comprising:

[0005] A housing having a jacking compartment;

[0006] Connector, the connector being installed within the card slot;

[0007] A protective sleeve assembly includes a protective sleeve and at least one first elastic element. The protective sleeve is movably disposed within the card slot and connected to the bottom of the card slot via the at least one first elastic element. The protective sleeve is configured to accommodate the card-type electronic device and, when the card-type electronic device is pressed into the card slot against the elastic force of the first elastic element, moves with the card-type electronic device from an unlocked position to a locked position. When the protective sleeve is in the locked position, the card-type electronic device is connected to the connector.

[0008] A locking component, at least partially disposed between the housing and the protective cover, the locking component being configured to lock the protective cover in a locked position or unlock the protective cover from the locked position.

[0009] The connecting device provided in this application enables the locking component to automatically lock the protective cover by inserting the card-type electronic device into the protective cover and pushing the protective cover to the locking position. When unlocking, the protective cover can be automatically popped out by simply sliding the locking piece, without the need to manually reach into the connecting device to pull out the card-type electronic device. This effectively reduces the difficulty of inserting and removing the card-type electronic device. At the same time, the locking component locks the card-type electronic device by locking the protective cover, and there is no contact between the locking component and the card-type electronic device throughout the process, which avoids damage to the locking component when the card-type electronic device is inserted or removed.

[0010] In some embodiments, the card compartment includes a first sidewall and a guide groove is formed on the first sidewall. The guide groove is substantially parallel to the depth direction of the card compartment. The protective sleeve includes a first sidewall opposite to the first sidewall and a limiting block disposed on the first sidewall. The protective sleeve is slidably disposed in the card compartment through the cooperation of the limiting block and the guide groove. The guide groove is configured to limit the sliding of the protective sleeve between the unlocked position and the locked position.

[0011] Thus, the limiting part and the guide groove are used to limit the sliding range of the protective sleeve and prevent the protective sleeve from sliding out of the housing.

[0012] In some embodiments, the locking assembly includes a locking member and a second elastic member. The locking mechanism is movably disposed within the card slot. The locking member is connected to the side wall of the housing via the second elastic member. The protective sleeve includes a second side surface and a first wedge-shaped slider disposed on the second side surface. The locking member includes a connecting surface opposite to the second side surface and a second wedge-shaped slider disposed on the connecting surface. The locking member is configured such that when the protective sleeve slides toward the locking position, the first wedge-shaped slider pushes the second wedge-shaped slider and, overcoming the elastic force of the second elastic member, drives the locking member to slide along the width direction of the card slot. When the protective sleeve slides to the locking position, the first wedge-shaped slider separates from the second wedge-shaped slider, and the locking member returns to its initial position under the elastic force of the second elastic member, thereby causing the second wedge-shaped slider to press against the first wedge-shaped slider to lock the protective sleeve. Alternatively, sliding the locking member causes the second wedge-shaped slider to move away from the first wedge-shaped slider to unlock the protective sleeve.

[0013] Thus, locking is achieved by the mutual pressing of the first and second wedge sliders. While ensuring the locking effect, this also simplifies the structure of the chuck and locking components and reduces the difficulty of processing.

[0014] In some embodiments, the first wedge-shaped slider has a connected first inclined surface and a first contact surface, the first contact surface being substantially perpendicular to the depth direction of the cartridge. The second wedge-shaped slider has a second inclined surface substantially parallel to the first inclined surface and a second contact surface substantially parallel to the first contact surface, the second inclined surface being connected to the second contact surface. The locking member is configured such that when the protective sleeve slides toward the locking position, the first wedge-shaped slider presses against the second inclined surface through the first inclined surface to push the second wedge-shaped slider, and under the condition of overcoming the elastic force of the second elastic member, it drives the locking member to slide along the width direction of the cartridge. When the protective sleeve slides to the locking position, the first inclined surface separates from the second inclined surface, and the locking member returns to its initial position under the elastic force of the second elastic member, thereby causing the second contact surface to press against the first contact surface to lock the protective sleeve, or, sliding the locking member causes the second contact surface to leave the first contact surface to unlock the protective sleeve.

[0015] In this way, the first and second inclined surfaces work together to push the second wedge slider with the first wedge slider, which helps to reduce the wear of the first and second wedge sliders. The protective sleeve is locked by the mutual pressing of the first and second wedge sliders. While ensuring the locking effect, it also helps to simplify the structure of the protective sleeve and locking parts and reduce the processing difficulty.

[0016] In some embodiments, the card compartment includes a second sidewall and a first groove is formed in the second sidewall. The locking member includes a sliding portion, and the locking member is at least partially slidably disposed in the card compartment through the cooperation of the sliding portion with the first groove. The guide of the first groove is substantially parallel to the width direction of the card compartment.

[0017] Thus, the first groove is used to limit the sliding range of the locking element, preventing the locking element from shifting during the sliding process and causing it to malfunction.

[0018] In some embodiments, there are multiple first wedge sliders, which are spaced apart along the width direction of the cartridge, and multiple second wedge sliders, which are arranged corresponding to the first wedge sliders.

[0019] Thus, having multiple first wedge sliders and multiple second wedge sliders helps to make the force more balanced when the first wedge slider pushes the second wedge slider, which helps to improve the service life.

[0020] In some embodiments, the locking assembly further includes an unlocking member comprising a connected body and an unlocking portion. The body is slidably disposed within the card slot. The locking member has an opening, and the unlocking portion extends at least partially into the opening. The end of the unlocking portion away from the body is inclined with a third inclined surface, and the edge of the opening is provided with a fourth inclined surface substantially parallel to the third inclined surface. The unlocking member is configured such that when the unlocking member is slid, the third inclined surface presses against the fourth inclined surface and pushes the locking member to slide along the width direction of the card slot against the elastic force of the second elastic member, thereby unlocking the protective cover.

[0021] In this way, by using the third and fourth inclined surfaces in combination to enable the unlocking part to push the locking component, the wear of the unlocking part and the locking component can be reduced.

[0022] In some embodiments, the locking member is further provided with a guide plate, which is disposed at the edge of the opening adjacent to or opposite to the fourth inclined surface.

[0023] In this way, the guide plate can guide the unlocking part, preventing it from coming out of the opening and causing the unlocking part to fail.

[0024] In some embodiments, the main body includes a button and a connecting rod. The housing has an opening through which the button extends. One end of the connecting rod is connected to the button, and the other end is connected to the unlocking part. The housing has a second sliding groove, and the connecting rod is slidably disposed in the second sliding groove. The unlocking part is slidably disposed in the card compartment through the cooperation of the connecting rod and the second sliding groove. The guide of the second sliding groove is substantially parallel to the depth direction of the card compartment.

[0025] In this way, unlocking can be achieved by pressing the button, which helps to reduce the difficulty of unlocking.

[0026] Another embodiment of the electronic device of this application includes the connection device described in any of the above claims.

[0043] Memory cards are widely used in various electronic devices as storage devices. During use, memory cards are typically inserted into electronic devices via a card ejector mechanism. However, most memory card ejector mechanisms are cumbersome to operate, lacking automated ejection functionality. Furthermore, the locking mechanism usually directly latches onto the memory card to secure it. This makes manually removing the memory card from the ejector mechanism inconvenient and can easily damage the locking mechanism during the process.

[0044] Please see Figure 1 This application provides an electronic device 1000, including a connection device 100. The connection device 100 includes a housing 10, a connector 20, a protective sleeve assembly 30, and a locking assembly 40. The housing 10 forms a card slot 11. The connector 20 is installed in the card slot 11. The protective sleeve assembly 30 includes a protective sleeve 31 and at least one first elastic member 32. The protective sleeve 31 is movably disposed in the card slot 11 and connected to the bottom of the card slot 11 through at least one first elastic member 32. The protective sleeve 31 is configured to accommodate a card-type electronic device 200. When the card-type electronic device 200 is pressed into the card slot 11 against the elastic force of the first elastic member 32, it moves with the card-type electronic device 200 from an unlocked position to a locked position. When the protective sleeve 31 is in the locked position, the card-type electronic device 200 is connected to the connector 20. The locking assembly 40 is at least partially disposed between the housing 10 and the protective sleeve 31. The locking assembly 40 is configured to lock the protective sleeve 31 in the locked position or unlock the protective sleeve 31 from the locked position.

[0045] The connecting device 100 provided in this application can automatically lock the protective cover 31 by inserting the card-type electronic device 200 into the protective cover 31 and pushing the protective cover 31 to the locking position. When unlocking, the protective cover 31 can be automatically popped out by simply sliding the locking piece 41, without having to manually reach into the connecting device 100 to pull out the card-type electronic device 200. This effectively reduces the difficulty of inserting and removing the card-type electronic device 200. At the same time, the locking component 40 locks the card-type electronic device 200 by locking the protective cover 31, without contacting the card-type electronic device 200 throughout the process, thus avoiding damage to the locking component 40 when the card-type electronic device 200 is inserted or removed.

[0046] For details, please refer to Figure 1 The electronic device 1000 provided in this application can be a portable communication device such as a mobile phone or tablet, or an electronic device 1000 such as a card reader. In this embodiment, the electronic device 1000 is exemplified by a card reader. The card-type electronic device 200 is exemplified by a memory card.

[0047] In the embodiments of this application, please refer to Figures 1 to 3 The shell 10 is divided into a front shell 12 and a rear shell 13. The front shell 12 and the rear shell 13 enclose a cavity. A first side wall 111, a second side wall 112 and a third side wall 113 are formed on the rear shell 13. A fourth side wall is formed on the front shell 12. The first side wall 111, the second side wall 112, the third side wall 113 and the fourth side wall enclose a compartment 11.

[0048] Please see Figure 1 and Figure 4 The protective cover 31 is a box-shaped structure with an opening on one side. The protective cover 31 includes a first side 311, a second side 312, a third side 313, a fourth side, and a bottom surface 314, and is slidably disposed in the card compartment 11.

[0049] The first elastic element 32 is reset by the protective sleeve 31. In this embodiment, the first elastic element 32 is a linear spring. Furthermore, a first mounting groove 14 is provided on the bottom inner wall of the housing 10, and a second mounting groove 319 is provided at the bottom of the protective sleeve assembly 30 to cooperate with the first mounting groove 14. One end of the first elastic element 32 is installed in the first mounting groove 14, and the other end is installed in the second mounting groove 319.

[0050] Please see Figure 5 The locking component 40 includes a locking element 41, which includes a connected sliding part 411 and a control part 413. The sliding part 411 is slidably disposed in the card slot 11 and between the housing 10 and the protective sleeve 31.

[0051] Please see Figure 4 and Figure 6In some embodiments, the connector 20 is disposed at the bottom of the card compartment 11, the top of the card compartment 11 extends through the housing 10 to form an opening 114, and the protective sleeve 31 forms an inlet 315 opposite to the opening 114 and an outlet 316 opposite to the connector 20.

[0052] This facilitates the installation of the card-type electronic device 200 and the connection between the card-type electronic device 200 and the connector 20.

[0053] Specifically, in this embodiment, the outlet 316 of the protective sleeve 31 is located on the ground, and the inlet 315 is located on the side away from the bottom surface 314.

[0054] In this embodiment, the card-type electronic device 200 can be inserted into the protective sleeve 31 through the opening 114. The card slot 11 is rectangular, and the protective sleeve 31 is slidably disposed along the length direction of the card slot 11, wherein the Y-axis direction is the length direction of the card slot 11. When the protective sleeve 31 slides to the opening 114, it is the unlocked position of the protective sleeve 31. When the protective sleeve 31 slides to a position far away from the opening 114, it is the locked position of the protective sleeve 31. When the protective sleeve 31 slides to the locked position, the connector 20 can pass through the outlet 316 and connect to the card-type electronic device 200. Alternatively, part of the card-type electronic device 200 passes through the outlet 316 and connects to the connector 20.

[0055] Please see Figure 6 In some embodiments, the connecting device 100 further includes a protective cover 50, which is rotatably disposed on the housing 10 and configured such that rotating the protective cover 50 opens or closes the opening 114.

[0056] Thus, the protective cover 50 can prevent the card-type electronic device 200 from falling out of the protective cover 31, and can also prevent moisture, dust, etc. from entering the connecting device 100 through the opening 114 and damaging the card-type electronic device 200 or the connecting device 100.

[0057] Specifically, in this embodiment, the protective cover 50 includes a cover body 51 and a rotating shaft 52, with the cover body 51 rotatably mounted on the housing 10 via the rotating shaft 52.

[0058] Furthermore, the protective cover 50 also includes a first buckle 53, which is located on the side of the cover 51 away from the pivot 52. The housing 10 is provided with a second buckle 15 that cooperates with the first buckle 53. The second buckle 15 is located at the edge of the opening 114 away from the pivot 52. When the protective cover 50 closes the opening 114, the first buckle 53 and the second buckle 15 cooperate to lock the protective cover 50.

[0059] Please see Figure 3 and Figure 6In some embodiments, the card compartment 11 includes a first sidewall 111, and a guide groove 115 is formed on the first sidewall 111. The guide groove 115 is substantially parallel to the depth direction of the card compartment 11. The protective sleeve 31 includes a first side surface 311 opposite to the first sidewall 111 and a limiting block 317 disposed on the first side surface 311. The protective sleeve 31 is slidably disposed in the card compartment 11 through the cooperation of the limiting block 317 and the guide groove 115. The guide groove 115 is configured to limit the sliding of the protective sleeve 31 between the unlocked position and the locked position.

[0060] Thus, the limiting part 4313 and the guide groove 115 are used to limit the sliding range of the protective sleeve 31 and prevent the protective sleeve 31 from sliding out of the housing 10.

[0061] Specifically, in this embodiment, the limiting block 317 is a protrusion protruding outward from the first side 311 of the protective sleeve 31. The first side wall 111 of the card compartment 11 is provided with a guide groove 115 arranged parallel to the depth direction of the card compartment 11. When the protective sleeve 31 is slidably disposed in the card compartment 11 through the mutually cooperating limiting block 317 and guide groove 115, the limiting block 317 is slidably disposed in the guide groove 115 to limit the sliding range of the protective sleeve 31.

[0062] Furthermore, there are two limiting blocks 317, which are respectively disposed on the first side 311 and the third side 313 of the protective sleeve 31. Similarly, there are two guide grooves 115, which are respectively disposed on the first side wall 111 and the third side wall 113 on both sides of the protective sleeve 31. When the protective sleeve 31 is slidably disposed in the card compartment 11, the two limiting blocks 317 are slidably disposed in the two guide grooves 115.

[0063] Please see Figure 1 In some embodiments, the first elastic element 32 includes a plurality of elements and is spaced apart along the width direction of the card slot 11.

[0064] Thus, the multiple first elastic elements 32 are used to reset the protective sleeve 31, which can make the protective sleeve 31 more evenly stressed, so that the protective sleeve 31 can pop out more stably.

[0065] Specifically, in this embodiment, the X-axis direction is the width direction of the card slot 11, and there are two first elastic elements 32. The two first elastic elements 32 are spaced apart on both sides near the bottom of the protective sleeve 31. Furthermore, both first elastic elements 32 are linear springs.

[0066] In other embodiments, the first elastic element 32 may also be configured in other quantities and types. The specific quantity and type of the first elastic element 32 can be selected according to actual needs, which will not be elaborated here.

[0067] Please see Figure 1 , Figure 4 , Figure 5 and Figure 7 In some embodiments, the locking assembly 40 includes a locking member 41 and a second elastic member 42. The locking mechanism is movably disposed within the card slot 11. The locking member 41 is connected to the side wall of the housing 10 via the second elastic member 42. The protective sleeve 31 includes a second side surface 312 and a first wedge-shaped slider 318 disposed on the second side surface 312. The locking member 41 includes a connecting surface opposite to the second side surface 312 and a second wedge-shaped slider 412 disposed on the connecting surface. The locking member 41 is configured such that when the protective sleeve 31 slides towards the locking position, the first wedge-shaped slider 318 pushes the second... The wedge slider 412, under the condition of overcoming the elastic force of the second elastic member 42, drives the locking member 41 to slide along the width direction of the card slot 11. When the protective sleeve 31 slides to the locked position, the first wedge slider 318 separates from the second wedge slider 412. The locking member 41 returns to the initial position under the elastic force of the second elastic member 42, so that the second wedge slider 412 presses against the first wedge slider 318 to lock the protective sleeve 31. Alternatively, the locking member 41 can be slid to make the second wedge slider 412 leave the first wedge slider 318 to unlock the protective sleeve 31.

[0068] Specifically, the first wedge slider 318 is a protrusion protruding outward from the second side 312 of the protective cover 31 near the rear shell 13. The second wedge slider 412 is disposed on the surface of the locking part near the protective cover 31. When the card-type electronic device 200 is inserted into the protective cover 31 and slides down, the first wedge slider 318 will press against the second wedge slider 412 and push the second wedge slider 412 to move the locking member 41. When the protective cover 31 slides to the locked position, the first wedge slider 318 and the second wedge slider 412 move relative to each other until they separate. At this time, the locking component 40 resets, causing the second wedge slider 412 to move to the top of the first wedge slider 318. The second wedge slider 412 presses against the first wedge slider 318 to lock the protective cover 31.

[0069] Furthermore, in some embodiments, the first wedge-shaped slider 318 is provided with a connected first inclined surface 3181 and a first contact surface 3182. The first inclined surface 3181 is substantially perpendicular to the first reference surface, and the first contact surface 3182 is substantially perpendicular to the depth direction of the cartridge 11. The first reference surface is substantially parallel to both the depth direction and the width direction of the cartridge 11. The second wedge-shaped slider 412 is provided with a second inclined surface 4121 substantially parallel to the first inclined surface 3181 and a second contact surface 4122 substantially parallel to the first contact surface 3182. The second inclined surface 4121 and the second contact surface 4122 are connected. The locking member 41 is configured such that the protective sleeve 31 is locked. When the position is slidable, the first wedge slider 318 presses against the second inclined surface 4121 through the first inclined surface 3181 to push the second wedge slider 412. Under the condition of overcoming the elastic force of the second elastic member 42, it drives the locking member 41 to slide along the width direction of the card slot 11. When the protective sleeve 31 slides to the locked position, the first inclined surface 3181 separates from the second inclined surface 4121. The locking member 41 returns to the initial position under the elastic force of the second elastic member 42, so that the second contact surface 4122 presses against the first contact surface 3182 to lock the protective sleeve 31. Alternatively, the locking member 41 can be slid to make the second contact surface 4122 leave the first contact surface 3182 to unlock the protective sleeve 31.

[0070] Thus, by using the first inclined surface 3181 and the second inclined surface 4121 in cooperation, the first wedge slider 318 pushes the second wedge slider 412, which helps to reduce the wear of the first wedge slider 318 and the second wedge slider 412. The protective sleeve 31 is locked by the mutual pressing of the first wedge slider 318 and the second wedge slider 412. While ensuring the locking effect, it helps to simplify the structure of the protective sleeve 31 and the locking part 41 and reduce the processing difficulty.

[0071] Specifically, in this embodiment, the first reference plane is parallel to the plane containing the second side wall 112 of the card compartment 11 and the second side surface 312 of the protective sleeve 31.

[0072] Both the first wedge slider 318 and the second wedge slider 412 are right-angled trapezoids. The plane of the first wedge slider 318 near the second wedge slider 412 is an inclined first slope 3181, the top surface of the first wedge slider 318 is a first contact surface 3182, the plane of the second wedge slider 412 near the first wedge slider 318 is an inclined second slope 4121, and the bottom surface 314 of the second wedge slider 412 is a second contact surface 4122.

[0073] When unlocking is required, the sliding locking member 41 moves the second contact surface 4122 to a position where it is misaligned with the first contact surface 3182. At this time, the protective sleeve 31 will pop outward under the action of the first elastic member 32. In this embodiment, the second elastic member 42 is also a linear spring. Furthermore, a third mounting groove 16 is provided on the inner side wall of the housing 10, and the control part 413 of the locking member 41 is provided with a fourth mounting groove 414 that is correspondingly fitted to the third mounting groove 16. One end of the second elastic member 42 is installed in the third mounting groove 16, and the other end is installed in the fourth mounting groove 414.

[0074] In some embodiments, during the sliding process of the protective sleeve 31, the contact surfaces of the first wedge slider 318 and the second wedge slider 412 can also be set as curved surfaces, such as cylindrical surfaces, spherical surfaces, etc.

[0075] Please see Figure 3 and Figure 6 In some embodiments, the card compartment 11 includes a second sidewall 112 and a first groove 1121 is formed in the second sidewall 112. The locking member 41 includes a sliding part 411. The locking member 41 is at least partially slidably disposed in the card compartment 11 through the cooperation of the sliding part 411 and the first groove 1121. The guide of the first groove 1121 is substantially parallel to the width direction of the card compartment 11.

[0076] Thus, the first groove 1121 is used to limit the sliding range of the locking member 41, preventing the locking member 41 from shifting during the sliding process and causing the locking member 41 to malfunction.

[0077] Specifically, in this embodiment, the first groove 1121 is disposed on the second sidewall 112 opposite to the second sidewall 312 of the protective sleeve 31 and is disposed in a direction parallel to the width of the card slot 11, and the sliding part 411 is slidably disposed on the first groove 1121.

[0078] Please see Figure 4 and Figure 5 In some embodiments, there are multiple first wedge sliders 318, which are spaced apart along the width direction of the cartridge 11. There are also multiple second wedge sliders 412, which are arranged corresponding to the first wedge sliders 318.

[0079] Thus, the multiple first wedge sliders 318 and multiple second wedge sliders 412 help to make the force more balanced when the first wedge slider 318 pushes the second wedge slider 412, which helps to improve the service life.

[0080] Specifically, in this embodiment, there are three first wedge sliders 318, which are evenly arranged on the same straight line. The straight line containing the three first wedge sliders 318 is parallel to the width direction of the cartridge 11. Similarly, there are three second wedge sliders 412, which are evenly arranged on the same straight line. The straight line containing the three first wedge sliders 318 is parallel to the width direction of the cartridge 11.

[0081] Furthermore, the three first wedge-shaped sliders 318 and the protective sleeve 31 are integrally formed into a single structure, and the three second wedge-shaped sliders 412 and the locking member 41 are integrally formed into a single structure.

[0082] Please see Figure 3 , Figure 8 and Figure 9 In some embodiments, the locking assembly 40 further includes an unlocking member 43, which includes a connected main body 431 and an unlocking part 432. The main body 431 is slidably disposed in the card slot 11. The locking member 41 is provided with an opening 415. The unlocking part 432 extends at least partially into the opening 415. The end of the unlocking part 432 away from the main body 431 is provided with a third inclined surface 4321, which is substantially perpendicular to the first reference plane. A fourth inclined surface 4151, which is substantially parallel to the third inclined surface 4321, is provided at the edge of the opening 415. The unlocking member 43 is configured such that when the unlocking member 43 is slid, the third inclined surface 4321 presses against the fourth inclined surface 4151 and pushes the locking member 41 to slide along the width direction of the card slot 11 in the case of overcoming the elastic force of the second elastic member 42, thereby unlocking the protective sleeve 31.

[0083] Thus, by using the third inclined surface 4321 and the fourth inclined surface 4151 in cooperation to enable the unlocking part 432 to push the locking component 40, it is beneficial to reduce the wear of the unlocking part 432 and the locking component 41.

[0084] Specifically, in this embodiment, the unlocking member 43 is disposed on the side of the protective sleeve 31 near the control part 413 of the locking component 40, the main body 431 is slidably disposed on the housing 10 along the depth direction of the card slot 11, and the control part 413 of the locking member 41 is provided with an opening 415.

[0085] Furthermore, the unlocking part 432 is a right-angled trapezoid, and the end of the unlocking part 432 away from the main body 431 is provided with a third inclined surface 4321. When the unlocking member 43 is pressed and slid along the depth direction of the card slot 11, the third inclined surface 4321 will press against the fourth inclined surface 4151 and push the locking component 40 to slide along the width direction of the card slot 11.

[0086] Please see Figure 3 and Figure 5In some embodiments, the locking member 41 is further provided with a guide plate 416, which is located at the edge adjacent to or opposite to the opening 415 and the fourth inclined surface 4151.

[0087] Thus, the guide plate 416 can guide the unlocking part 432, preventing the unlocking part 432 from coming out of the opening 415 and causing the unlocking part 43 to fail.

[0088] Specifically, the guide plate 416 is disposed at the edge of the opening 415 and abuts against the side of the unlocking part 432. In this embodiment, there are two guide plates 416. The two guide plates 416 are respectively disposed at the two edges adjacent to the opening 415 and the fourth inclined surface 4151. The two guide plates 416 are disposed opposite to each other, and the unlocking part 432 is disposed between the two guide plates 416.

[0089] Furthermore, the two guide plates 416 and the locking assembly 40 are integrally formed as a single structure.

[0090] Please see Figure 3 and Figure 9 In some embodiments, the main body 431 includes a button 4311 and a connecting rod 4312. The housing 10 is provided with an opening 17. The button 4311 extends out of the opening 17. One end of the connecting rod 4312 is connected to the button 4311, and the other end is connected to the unlocking part 432. The housing 10 is provided with a second sliding groove 18. The connecting rod 4312 is slidably disposed in the second sliding groove 18. The unlocking part 43 is slidably disposed in the card compartment 11 through the cooperation of the connecting rod 4312 and the second sliding groove 18. The guide of the second sliding groove 18 is basically parallel to the depth direction of the card compartment 11.

[0091] Thus, unlocking can be achieved by pressing button 4311, which helps to reduce the difficulty of unlocking.

[0092] Specifically, in this embodiment, the cross-sectional shape of the button 4311 and the shape of the opening 17 are both square, the size of the opening 17 is slightly larger than the cross-sectional size of the button 4311, the connecting rod 4312 is cylindrical, and the diameter of the connecting rod 4312 is smaller than the width of the button 4311 and the unlocking part 432.

[0093] Furthermore, the housing 10 is provided with a sliding groove, and the connecting rod 4312 is slidably disposed in the sliding groove. When the button 4311 is pressed, the button 4311 will push the locking component 40 to slide through the unlocking part 432, thereby unlocking the protective cover 31.

[0094] In some embodiments, the main body 431 further includes a limiting part 4313, which presses against the edge of the opening 17 when the locking part is in the initial position.

[0095] Thus, the first limiting part 4313 can restrict the unlocking part 43 inside the housing 10, preventing the unlocking part 43 from detaching from the housing 10 from the opening 17.

[0096] Specifically, in this embodiment, the limiting part 4313 is disposed at the edge of the button 4311 near the connecting rod 4312. The limiting part 4313 is arranged in a ring around the button 4311. The width of the limiting part 4313 is slightly larger than the width of the opening 17, so that the limiting part 4313 can restrict the button 4311 inside the housing 10 and prevent it from coming out of the opening 17.

[0097] Furthermore, the button 4311, the connecting rod 4312, the limiting part 4313, and the unlocking part 432 are all integrally machined into a single structure.
