Description

Technical Field

[0001] This application relates to the technical field of fixed card seats, and particularly relates to a SIM card locking self - ejecting card seat. Background Technique

[0002] With the rapid development of communication technology, as an important part of mobile communication devices, the security and convenience of SIM cards have attracted more and more attention from users. At present, the designs of SIM card slots on the market are diverse, but most of them have problems such as complex operation and low security. For example, traditional SIM card slots require users to use tools to pick out the SIM card, which is not only inconvenient to operate but also easily causes damage to the SIM card or the card slot. In addition, although some designs consider the self - eject function, the locking mechanism is not perfect, which easily leads to accidental detachment of the SIM card.

[0003] The invention patent publication number CN114899631A discloses a SIM card seat with a double self - eject mechanism, including an insulating base and a fixing strip. The inner cavity of the insulating base is welded with frames on both sides. In this invention, after the fixing strip is pushed to the maximum limit, the fixing sleeve will be stuck by the elastic C - shaped plates in the grooves due to the rectangular through - holes on both sides of it. At this time, with the help of the large elasticity and toughness of the elastic C - shaped plates, the fixing sleeve is locked, thereby fixing the SIM card supporting frame on the fixing strip in the inner cavity of the insulating base. When it is necessary to remove the SIM card, the tip of the card pin is inserted into the fixing sleeve through the through - hole on the fixing strip. The externally inserted card pin extrudes the part of the elastic C - shaped plate extending into the fixing sleeve outside the fixing sleeve. Synchronously, with the help of an external force to pull the fixing strip outwards, the elastic C - shaped plate can be completely separated from the rectangular through - holes on both sides of the fixing sleeve, and the return spring pushes the movable sleeve in the reverse direction, and uses the Z - shaped rod to eject the SIM card supporting frame out of the inner part of the insulating base, achieving the self - eject effect. The above - mentioned SIM card seat requires inserting a card pin and pulling the fixing strip outwards during the rebound, resulting in a more cumbersome rebound operation of the SIM card, which is not conducive to the convenient operation of installing and removing the SIM card. Summary of the Invention

[0004] In order to solve the problem of the cumbersome rebound operation of the SIM card seat, this application provides a SIM card locking self - ejecting card seat.

[0005] The SIM card locking self - ejecting card seat provided by this application adopts the following technical solutions:

[0006] A SIM card locking self - ejecting card seat includes:

[0007] A base, which has an installation area and a control area. The installation area is for installing the SIM card, and an elastic member is connected to the side wall of the control area;

[0008] The control member and the control rod are both disposed in the control area. The control member is connected to the elastic member and is provided with a connecting portion protruding from the installation area. The connecting portion is for inserting a SIM card to drive the control member to move. The control member has a plurality of control points and control routes connecting the control points. The connecting end of the control rod is connected to the base and can rotate relative to the base. The control end is located within the control points or control routes. When the control member is driven by the SIM card, the control rod moves between the control points through the control route to achieve locking and self-elasticity of the control member;

[0009] The cover plate is connected to the base and covers the control member and the control rod.

[0010] By adopting the above technical solution, a space is formed between the base and the cover plate. The space corresponding to the installation area is for installing the SIM card, and the space corresponding to the control area is for installing the control member, the control rod and the elastic member capable of locking and self-elasticating the SIM card. The connecting portion connects the control member and can abut against the SIM card. By pushing the connecting portion of the SIM card, the control member can be pushed to move, and the elastic member can eject the SIM card through the control member and the connecting portion. The connecting end of the control rod is rotatably connected to the base, and the control end of the other end moves on the control points and control routes in the control member. After the SIM card is inserted into the card seat, the control rod and the control member are engaged to lock the SIM card. When it is necessary to take out the SIM card, the engagement can be released and the SIM card can be ejected, making the operation more convenient.

[0011] Optionally, the control points include a first control point, a second control point, a third control point and a fourth control point. When the SIM card is not inserted, the control end of the control rod is located at the first control point. After the SIM card is inserted and pressed to the end, the control end of the control rod moves to the second control point. After releasing the SIM card, the control member rebounds under the action of the elastic member, and the control end of the control rod moves to the third control point. The control rod forms an engagement with the control member at the third control point to fix the position of the control member. After pressing the SIM card to the end again, the control end of the control rod moves to the fourth control point. After releasing the SIM card, the control member ejects the SIM card through the connecting portion under the action of the elastic member, and the control rod returns to the first control point.

[0012] By adopting the above technical solution, by pressing the SIM card, the control member is pushed to move. After the control end of the control rod passes through the second position point, it is clamped at the third position point to form a lock so that the SIM card cannot be ejected. After pressing again, when the control end of the control rod is pushed to the fourth position point, under the action of the elastic member, the SIM card can be ejected, and the control end of the control rod returns to the first position point. By providing control position points, the SIM card can be locked after one press and unlocked and ejected after pressing again, making the locking and self-ejecting operation more convenient.

[0013] Optionally, the control route includes a first route, a lifting portion, a second route, a third route, and a fourth route. The first route and the lifting portion are located between the first position point and the second position point. The second route is located between the second position point and the third position point. The third route is located between the third position point and the fourth position point. The fourth route is located between the fourth position point and the first position point. The lifting portion can lift the control end of the control rod. Steps are provided between the lifting portion and the second position point, between the second route and the third position point, between the third route and the fourth position point, and between the fourth route and the first position point to prevent the control end of the control rod from moving in the reverse direction.

[0014] By adopting the above technical solution, after the lifting portion lifts the control end, each time the control end passes through the control position point, it can fall onto the step, thereby preventing the control rod from moving in the reverse direction, ensuring that the control rod moves along the specified route, and making the operation of the card seat more stable.

[0015] Optionally, protrusions are provided at one end of the second route close to the third position point and one end of the third route close to the third position point.

[0016] By adopting the above technical solution, since the third position point is the position point where the control rod and the control member are clamped, by providing protrusions both when entering and leaving the third position point, additional pushing resistance can be increased to let the operator feel the formation of the clamping. And the resistance formed by the protrusions can prevent the clamping from being released due to accidental touch, ensuring the stability of the SIM card lock.

[0017] Optionally, the cover plate has a pressing piece, and the pressing piece abuts against the control rod for pressing the control rod so that the control end of the control rod remains in contact with the control position point and the control route.

[0018] By adopting the above technical solution, the pressing piece is used to abut against and press the control rod above the control rod to ensure that the control end of the control rod remains within the control position point and the control route. Since there are multiple steps in the control route, there will be a position difference in the vertical direction. With the pressing piece, it is ensured that the control rod does not cross the steps and move in the opposite path, thereby ensuring the stable operation of the card group.

[0019] Optionally, the base is provided with a mounting block, and the cover is provided with a mounting groove, and the mounting block is snap-fitted with the mounting groove to fix the base and the cover.

[0020] By adopting the above technical solution, the clamping connection between the mounting block and the mounting groove can facilitate the quick connection and removal of the cover plate and the base, and ensure a stable connection between the two.

[0021] Optionally, the base is provided with an electrical connector and a limit block, and the cover is provided with a mounting plate.

[0022] By adopting the above technical solution, the electrical contact piece is used to realize the electrical connection between the SIM card and the card holder, so that the data in the SIM card can be transmitted to the outside. The limit block is used to fit the shape of the SIM card at a corner, so as to avoid the SIM card from being installed in the wrong direction. The installation piece is an elastic piece, which can press the SIM card in the card holder tightly, so that the electrical contact piece is close to the SIM card, so that the SIM card can be installed and connected stably in the card holder and will not fall out easily.

[0023] Optionally, the pressing plate has a groove portion and a toggle portion, the groove portion corresponds to the third position, and when the control end of the control rod is located at the third position, the control rod forms a clamping connection with the pressing plate in the groove portion, and the toggle portion is used to lift the pressing plate to release the clamping connection between the pressing plate and the control rod.

[0024] By adopting the above technical solution, since the connecting end of the control rod is rotatably connected to the base, although the motion trajectory of the control rod is complex when it moves relative to the control member, the control rod only rotates in the horizontal direction relative to the base. The pressing sheet is pressed on the upper side of the control rod by elastic action on the control rod, so the pressing sheet is always in contact with the control rod. The pressing sheet has a groove portion corresponding to the third position. When the control end is located at the third position, the groove portion can form a snap connection with the control rod, so that the control rod cannot move left and right. When the control end leaves the third position, the control rod needs to move to the left and right ends. Therefore, when the groove portion forms a snap connection with the control rod, the snap connection of the control end at the third position cannot be released by pushing the SIM card, thereby avoiding the SIM card ejection caused by errors and improving the stability of the card holder.

[0025] Optionally, the pressing sheet further has a sliding portion, which is disposed at an edge of the groove portion and is used to enable the control rod to slide through the groove portion along the fourth route.

[0026] By adopting the above technical solution, when the control end returns to the first position through the fourth route at the fourth position, the control rod needs to pass through the groove part again, and the groove part will form a clamping connection with the control rod, hindering the control end from returning to the first position. Therefore, a sliding part is provided at the edge of the groove part. When the control rod moves towards the sliding part, the control rod can slide over the groove part, thus avoiding the groove part from obstructing the control rod. Since the sliding part corresponds to the direction of the second route, and the clamping connection between the groove part and the control rod mainly prevents the control rod from entering the third route, and there is a step in the second route direction to form a clamping connection, the sliding part will not affect the clamping connection between the groove part and the control rod.

[0027] Optionally, the fourth route has a transition area, and the vertical position of the transition area is lower than the rest of the fourth route and corresponds to the position of the groove part.

[0028] By adopting the above technical solution, the vertical position of the transition area is relatively reduced to reduce the horizontal position of the control rod. Since the control rod forms a clamping connection at the third position and the vertical position of the control rod is relatively high, and within the fourth route, the vertical position of the control rod is reduced. By further reducing the vertical position of the control rod through the transition area, the pressing piece that presses against the control rod above the control rod can reduce the amplitude of pressing the control rod, and then cooperate with the sliding part to enable the control rod to better slide over the groove part.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The connecting end of the control rod is rotatably connected to the base, and the control end at the other end moves on the control positions and control routes within the control member. When the SIM card is inserted into the card holder, the control rod and the control member form a clamping connection, thereby locking the SIM card. When it is necessary to take out the SIM card, the clamping connection can be released to eject the SIM card, making the operation more convenient;

[0031] 2. The pressing piece has a groove part corresponding to the third position. When the control end is at the third position, the groove part can form a clamping connection with the control rod, so that the control rod cannot move left and right. When the control end leaves the third position, the control rod needs to move to the left and right ends. Therefore, when the groove part forms a clamping connection with the control rod, the clamping connection of the control end at the third position cannot be released by pushing the SIM card, avoiding the SIM card from being ejected due to errors and improving the stability of the card holder;

[0032] 3. A sliding part is provided at the edge of the groove part. When the control rod moves towards the sliding part, the control rod can slide over the groove part, thus avoiding the groove part from obstructing the control rod; by further reducing the vertical position of the control rod through the transition area, the pressing piece that presses against the control rod above the control rod can reduce the amplitude of pressing the control rod, and then cooperate with the sliding part to enable the control rod to better slide over the groove part.

[0039] The present application is further described in detail below in conjunction with the accompanying drawings.

[0040] A SIM card locking self-ejecting card holder, referring to Figure 1, including a base 1, an elastic member 6, a control member 2, a control rod 3, and a cover plate 5. An installation area 11 and a control area 12 are provided on the base 1. The installation area 11 is used for installing the SIM card, while the control area 12 is used for placing control components such as the elastic member 6, the control member 2, and the control rod 3 to control the locking and ejection of the SIM card in the card holder. In the control area 12, the elastic member 6 is connected to the side wall to provide a restoring force for the control member 2. Both the control member 2 and the control rod 3 are located in the control area 12. The control member 2 is connected to the elastic member 6 and has a connecting portion 23 protruding into the installation area 11. The connecting portion 23 extends out of the installation area 11 so that after the SIM card is inserted, a corner of the SIM card can abut against the connecting portion 23, thereby driving the control member 2 to move by pushing the connecting portion 23. The control member 2 is provided with a plurality of control points 21 and a control route 22 connecting these control points 21. One end of the control rod 3 is connected to the base 1 and can rotate relative to the base 1 as a connecting section, while the other end can move in the control point 21 or the control route 22 as a control end 32. When the SIM card is inserted and pushes the connecting portion 23 to drive the control member 2, the control member 2 will move relative to the control rod 3, so that the control end 32 moves in the control point 21 and the control route, and forms a clamping and releasing of the clamping to achieve the purpose of locking and ejecting the SIM card. The cover plate 5 covers the base 1 to protect the internal control member 2, the control rod 3, and the inserted SIM card from interference.

[0041] Referring to the figure, the control points 21 include a first point 211, a second point 212, a third point 213, and a fourth point 214. The control route includes a first route 221, a lifting portion 225, a second route 222, a third route 223, and a fourth route 224. Among them, the first route 221 and the lifting route are located between the first point 211 and the second point 212, the second route 222 is located between the second point 212 and the third point 213, the third route 223 is located between the third point 213 and the fourth point 214, and the fourth route 224 is located between the fourth point 214 and the first route 221. The lifting portion 225 is a route with one end inclined upward, thereby raising the relative position of the control end 32 and providing a horizontal distance for the subsequent clamping of the control route. The first point 211 is located on the side away from the connecting end 31. When the SIM card is not inserted, the control end 32 of the control rod 3 stays at the first point 211. The second point 212 is located on the side close to the connecting end 31. The lifting portion 225 is connected to the second point 212, and a vertical step 226 is formed between the lifting portion 225 and the second point 212. After the SIM card is inserted and pushed to the end, the control member 2 moves in the direction away from the connecting end 31, and the control end 32 moves from the first point 211 to the second point 212 and is restricted by the step 226 at the second point 212 and cannot slide back into the lifting portion 225 again.

[0042] Referring to the figure, the third position point 213 is located at a position relatively farther from the connection end 31 than the second position point 212, and the third track extends towards the direction of the connection end 31. Therefore, the control end 32 will form a snap connection with the control member 2 at the third position point 213. In addition, protrusions 227 are provided at one ends of the second route 222 and the third route 223 close to the third position point 213. When the control end 32 enters or leaves the third position point 213, a resistance will be generated, so that the operator can sense the formation and release of the snap connection. When the SIM card is released, the control member 2 rebounds under the action of the elastic member 6, causing the control end 32 to move to the third position point 213 to achieve locking. Moreover, a step 226 is also formed between the second route 222 and the third position point 213, so that the control end 32 cannot slide back into the second route 222. The fourth position point 214 is located on the side close to the connection end 31. When the SIM card is pushed to the end again, the control end 32 moves to the fourth position point 214 through the third route 223. A step 226 is provided between the fourth position point 214 and the third route 223, so that the control end 32 cannot slide into the third route 223 again. After the control end 32 enters the fourth position point 214, it can no longer form a snap connection with the control member 2. After the SIM card is released, the control member 2 pops outwards under the action of the elastic member 6, and the control end 32 returns from the fourth position point 214 to the first route 221 through the fourth route 224, and finally returns to the first position point 211. A step 226 is also provided at the connection between the fourth route 224 and the first route 221 to prevent the control end 32 from sliding wrongly into the fourth route 224 within the first route 221. As the control end 32 returns to the first position point 211, the control member 2 also pops out the SIM card through the connection portion 23. Through the setting of the control position points 21 and the control routes, the locking and self-ejecting operations can be completed by pressing the SIM card.

[0043] Referring to the figure, a pressing piece 51 is provided on the cover plate 5. The pressing piece 51 is correspondingly installed above the control rod 3 and contacts the control rod 3. The control rod 3 applies a downward force so that the control rod 3 can always keep in contact with the control position 21 and the control route. Since the control end 32 needs to pass through the step 226 during the movement, it needs to keep in contact with the downward direction to ensure the normal operation of the control rod 3 and the control member 2. The pressing sheet 51 is provided with a groove portion 511, a toggle portion 512 and a sliding portion, wherein the groove portion 511 corresponds to the third position 213. When the control end 32 is engaged at the third position 213, the groove portion 511 will also be engaged with the control rod 3, so that the control end 32 of the control rod 3 cannot move in the direction of the third route 223. When the SIM card is locked, accidentally touching or pressing the SIM card may cause the SIM card to be ejected. The control rod 3 is engaged by the groove portion 511. Even after the SIM card is pressed, the control end 32 cannot be engaged at the third position 213 because the groove portion 511 will limit the movement of the control rod 3 to the right, i.e., in the direction of the third route 223. The groove portion 511 is provided to improve the locking capability of the self-ejecting card holder. The push portion 512 is a slightly raised structure, allowing the user to push the pressing piece 51 upward to release the engagement between the groove portion 511 and the control rod 3 . At this time, by pressing the SIM card, the control end 32 enters the third route 223 and reaches the fourth position 214 .

[0044] Referring to the figure, the fourth route 224 is provided with a transition zone 228, which is a groove structure and is arranged corresponding to the third position 213. Since the control end 32 will pass through the groove portion 511 of the pressing sheet 51 again during the process of the fourth route 224 returning to the first route 221, although the vertical position of the fourth route 224 is lower than the third position 213, it will still form a clamping connection with the groove portion 511. Therefore, it is necessary to further lower the vertical position of the control rod 3 through the transition zone 228 with a groove structure to reduce the contact between the control rod 3 and the edge of the groove portion 511. The front end portion of the edge of the groove portion 511 close to the first position 211 is also correspondingly provided as a sliding portion that allows the control rod 3 to slide through. The sliding portion is a slightly tilted structure. Under the push of the elastic member 6, the control rod 3 moves quickly in the fourth route 224, and under the action of the transition zone 228 and the sliding portion, it quickly passes through the groove portion 511, so that the control end 32 can normally return from the fourth position 214 to the first position 211.

[0045] Referring to the figure, the base 1 is provided with an electric contact 14, a mounting block 13 and a limit block 15, and the cover plate 5 is provided with a mounting piece 53 and a mounting groove 52. The electric contact 14 and the mounting piece 53 are arranged at positions corresponding to the mounting area 11, and are used to clamp and fix the SIM card inserted into the mounting area 11. The electric contact 14 can also complete the electrical connection by contacting the SIM card, thereby reading the data in the SIM card. The mounting block 13 and the mounting groove 52 cooperate with each other to fix the base 1 and the top cover, making the separation and installation of the base 1 and the top cover more convenient. The limit block 15 is used to cooperate with the missing corner on the SIM card to limit the insertion direction of the SIM card.

[0046] The implementation principle of the embodiment of the present application is: by pushing the connection part 23 through the SIM card connection, the control end 32 of the control rod 3 moves in the control member 2, and with the action of the pressing sheet 51, the control rod 3 can be connected with the control member 2 and the pressing sheet 51, so as to control the rebound of the control member 2, so that the SIM card is locked inside the card holder under the action of the installation sheet 53 and the electrical contact sheet 14. The connection formed by the control rod 3 and the pressing sheet 51 can prevent the control end 32 of the control rod 3 from moving to the third route 223 at the third position 213, so that the SIM card will not be ejected from the card holder even if it is pressed by mistake. When it is necessary to eject the SIM card, the pressing sheet 51 is slightly lifted by the toggle part 512, and then the SIM card is pressed, so that the control end 32 can move out of the third position 213, so that the control member 2 can eject the SIM card through the connection part 23 under the action of the elastic member 6.

[0047] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
