[0037] Please refer to Figures 1 to 9 The SIM card holder removal device 100 proposed by the utility model includes:

[0038] Housing 10;

[0039] A driving module, the driving module includes a motor 20 and a transmission assembly 30, the motor 20 and the transmission assembly 30 are arranged in the housing 10; a worm 31 is fixedly arranged on the output shaft of the motor 20, and the transmission assembly 30 is meshed with the worm 31; and

[0040] A push rod 40, which is movably disposed on the housing 10, and is provided with a meshing rack 401, which meshes with the transmission assembly 30;

[0041] When the motor 20 is in the forward rotation state, the push rod 40 can push the SIM card holder out.

[0042] In the technical solution of the utility model, a SIM card holder removal device 100 is applied to a mobile terminal and is arranged inside the mobile terminal. The motor is electrically connected to the circuit board of the mobile terminal to obtain a power source. The SIM card holder removal device 100 is connected to the SIM card holder structure. When the motor rotates forward, the worm gear sleeved on the motor output shaft drives the transmission component to rotate, and then the transmission component drives the push rod to move outward so that the push rod can push out the SIM card holder structure, thereby removing the SIM card; when the motor reverses, the worm gear sleeved on the motor output shaft drives the transmission component to reverse, and then the transmission component drives the push rod to move inward so that the push rod can be reset, and then the SIM card holder structure is placed and pressed to reset. In summary, the SIM card holder structure can be automatically pushed out under the drive of the motor, which avoids the need to use a card removal tool to complete the card removal action, avoids damage to the mobile terminal during the card removal action, and avoids the SIM card being removed by violent card removal, thereby realizing anti-theft kinetic energy.

[0043] The shell 10 may be a closed structure consisting of an upper shell 11 and a lower shell 12. The upper shell 11 and the lower shell 12 enclose a cavity for installing the drive module and the push rod 40 to protect the drive module and the push rod 40. The upper shell 11 and the lower shell 12 may be fixed to the inside of the mobile terminal by screws and other locking members; it may also be an open structure consisting of an upper cover 13 and a lower cover 14. Part of the structure of the upper cover 13 or the lower cover 14 may be set to a bent shape, and then a motor fixing hole is opened on the bent structure, and the output shaft of the drive motor 20 is passed through and fixed in the motor fixing hole. It can be understood that the specific shape of the shell 10 is not limited here.

[0044] The driving module includes a motor 20 and a transmission assembly 30. In order to reduce the overall size of the SIM card holder removal device 100, the motor 20 is a micro motor 20. The wiring terminals of the motor 20 are electrically connected to the circuit board of the mobile terminal through wires so as to receive a forward rotation command or a reverse rotation command issued by the mobile terminal, thereby realizing the forward movement or retraction of the push rod. Furthermore, in order to reduce the structural cost, the motor 20 can be selected as an ordinary motor different from a servo motor or a stepper motor. Of course, the selection of the motor 20 can be adjusted according to the actual control accuracy, control accuracy, and corresponding speed requirements, which are not limited here; the motor 2 0 is fixedly sleeved with a worm 31, and a transmission assembly 30 meshing with the worm 31 is provided inside the housing 10. The transmission assembly 30 is composed of a plurality of gears meshing in sequence. It can be understood that the number of gears in the transmission assembly 30, the number of teeth of each gear and other settings do not ultimately determine whether the SIM card holder can be pushed out or pulled back, but only affect the displacement performance such as the moving distance or moving speed of the SIM card holder structure 200. Therefore, the number of gears in the transmission assembly 30, the number of teeth of each gear and other settings are not limited here, as long as the SIM card holder can undergo corresponding displacement under the rotation of the motor 20.

[0045] The push rod 40 is movably arranged on the shell 10. Specifically, a hole structure for the push rod 40 to pass back and forth can be opened on the shell 10, so that the push rod 40 can directly or indirectly contact the SIM card seat structure 200; the push rod 40 is provided with a meshing rack 401, and the extension direction of the meshing rack 401 determines the moving direction of the push rod 40. Therefore, adaptive adjustment can be made according to the actual position layout of the SIM card seat removal device 100 and the SIM card seat, the cavity margin of the shell 10, and the layout of the motor 20 and the transmission assembly 30 in the shell 10 to ensure that the components do not cause interference problems in the working state; in this embodiment In the embodiment, the push rod 40 is a straight rod structure with a square cross section, and the cross section of the hole structure is also square. The meshing rack 401 is arranged on the side of the push rod 40 facing the motor 20, and a groove structure is opened on the push rod 40 away from the hole structure close to the housing 10, and then a connecting rod structure is connected between the groove structure and the SIM card holder. The connecting rod structure can be rotatably arranged inside the mobile terminal, so that during the movement of the push rod 40, the two ends of the connecting rod structure rotate around the rotation point, thereby pushing the SIM card holder structure 200 out of the mobile terminal, and then the push rod 40 rotates and resets under the control of the mobile terminal to put the SIM card holder. It can be understood that the invention concept proposed by the utility model focuses on realizing automatic card retrieval, so the specific structural form of the push rod 40 is not limited here.

[0046] In one embodiment, if Figure 3 and Figure 6 As shown, the transmission assembly 30 includes a helical gear 301 and at least one spur gear 302 , the helical gear 301 meshes with the worm 31 and any spur gear 302 , and any spur gear 302 meshes with the meshing rack 401 .

[0047] In this embodiment, the transmission assembly 30 includes a bevel gear 301 and three spur gears 302, and the three spur gears 302 are meshed in sequence, wherein one spur gear 302 is meshed with the bevel gear 301, and another spur gear 302 is meshed with the meshing rack 401, and the bevel gear 301 is meshed with the worm 31. In this way, since the gears and the meshing rack 401 are not self-locking, and the helix angle of the worm 31 is smaller than the friction angle of the contact between the worm 31 and the bevel gear 301 when the bevel gear 301 and the worm 31 are meshed, the static friction force can prevent the bevel gear 301 from reversing, thereby achieving the position locking of the push rod 40; when the SIM card holder removal device 100 is applied to a mobile terminal, after the SIM card holder is removed, the mobile terminal issues a command to reverse the motor 20, thereby driving the push rod 40 to reset and re-insert the SIM card holder structure 200, thereby preventing the problem of premature placement of the SIM card holder structure 200 due to operational errors, which eventually compresses the gears and causes gear wear, thereby extending the service life.

[0048] In one embodiment, if Figure 3 and Figure 6 As shown, the transmission assembly 30 includes at least two gears meshing in sequence, one of which meshes with the worm 31 , and the other meshes with the meshing rack 401 . The total transmission ratio of the at least two gears is M, and M is less than 1.

[0049] In this embodiment, the transmission assembly 30 includes four gears meshing in sequence, and each gear has two stacked teeth, so as to realize staggered meshing of multiple gears to avoid interference, wherein the gear of the transmission assembly 30 close to the worm 31 meshes with the worm 31, and the gear of the transmission assembly 30 close to the meshing rack 401 meshes with the meshing rack 401 to realize torque transmission; further, the transmission assembly 30 composed of four gears is a reduction transmission structure, and the total transmission ratio M is less than 1. The torque of the motor 20 is amplified by the transmission assembly 30 so that the push rod 40 can be quickly pushed out or retracted, saving card retrieval time. It can be understood that the specific total rotation ratio can be adaptively adjusted according to the mass of the push rod 40 and the friction between the push rod 40 and the outside world, which is not limited here.

[0050] In one embodiment, if Figure 3 and Figure 6 As shown, the gear unit includes a plurality of gears, one of which is meshed with the worm 31 , and another gear is meshed with the meshing rack 401 ; each gear is provided with a central transmission shaft 33 , and both ends of the central transmission shaft 33 are respectively inserted into the housing 10 .

[0051] In this embodiment, the transmission assembly 30 includes four gears meshing in sequence, each gear has two stacked teeth, and multiple gears are staggered and meshed to avoid interference. The gear of the transmission assembly 30 close to the worm 31 meshes with the worm 31, and the gear of the transmission assembly 30 close to the meshing rack 401 meshes with the meshing rack 401 to achieve torque transmission. In order to prevent the mobile terminal from vibrating due to external forces and causing the gears to loosen, each gear is provided with a central transmission shaft 33, and the two ends of the central transmission shaft 33 are respectively inserted into the shell 10 to fix the position of the gears.

[0052] In one embodiment, if Figures 2 to 5 As shown, the housing 10 includes an upper cover 13, a lower cover 14 and a support column 15 connecting the upper cover 13 and the lower cover 14, the motor 20 is fixed to the upper cover 13, and the transmission assembly 30 is arranged between the upper cover 13 and the lower cover 14; the upper cover 13 is provided with a first guide portion 131 protruding toward the lower cover 14, and the push rod 40 is provided with a first guide groove 40a, and the first guide portion 131 is inserted into the first guide groove 40a.

[0053] In the present embodiment, the housing 10 includes an upper cover 13, a lower cover 14, and a support column 15 connecting the upper cover 13 and the lower cover 14. At this time, the housing 10 is an open structure. This design is conducive to compressing the volume of the SIM card holder removal device 100 and reducing the space required for installing the SIM card holder removal device 100. The cross-sectional shape of the upper cover 13 is "L". A motor fixing arm 132 is protruding from one side of the upper cover 13 toward the lower cover 14. The motor fixing arm 132 is provided with a motor fixing hole. The output shaft of the motor 20 is inserted into the motor fixing hole so that the motor 20 is fixed to the upper cover 13, and the transmission assembly 30 is fixed between the upper cover 13 and the lower cover 14; further, a first guide portion 131 is protruding from the other side of the upper cover 13 toward the lower cover 14, and the push rod 40 is provided with a first guide groove 40a. The first guide portion 131 is inserted into the first guide groove 40a. When the SIM card holder removal device 100 is in an assembled state, the push rod 40 is limited between the upper cover 13 and the lower cover 14, and the motor When the push rod 40 rotates, the push rod 40 moves along the length extension direction of the first guide portion 131 to prevent the push rod 40 from moving in a biased direction; further, in the present embodiment, a push plate 404 is provided at the end of the push rod 40, and the push plate 404 and the push rod 40 are an integrally formed structure. The cross section of the push plate 404 is the same as the cross section of the push rod 40 and the cross section of the push plate is larger than the cross section of the push rod 40. Driven by the motor 20, the push rod 40 moves outward, and the push plate 404 can directly abut the SIM card holder structure 200 and push the SIM card holder structure 200 to move outward, or it can be indirectly connected to the SIM card holder structure 200 through the connecting rod structure 50. Under the push of the push plate 404, the connecting rod structure 50 moves outward to push out the SIM card holder structure 200, and then the motor 20 reverses to drive the push rod 40 to reset. When the SIM card holder structure 200 is reset, the connecting rod structure 50 is pushed inward to reset and move so that the connecting rod structure 50 abuts the push plate 404 again. It can be understood that, in the technical concept of the present invention, the movement mode of the connecting rod structure 50 is not limited, and can be adaptively changed according to the type of mobile terminal. For example, in the present embodiment, due to the layout requirements of the internal structure of the mobile terminal, the SIM card holder removal device 100 and the SIM card holder structure 200 are spaced apart along the moving direction of the push rod 40. At this time, the movement of the connecting rod structure 50 is mobile; in another embodiment, due to the layout requirements of the internal structure of the mobile terminal, the SIM card holder removal device 100 and the SIM card holder structure 200 are spaced apart along the moving direction of the vertical push rod 40, that is, arranged on the upper and lower sides. At this time, the movement of the connecting rod structure 50 is rotational. At the same time, under different movement types, the end of the push rod 40 can be adaptively changed to meet actual needs.

[0054] In one embodiment, if Figure 3As shown, the first guide portion 131 is provided with a movable limiting groove 13a, and the first guide groove 40a is provided with a limiting column 403, and the limiting column 403 is limited in the movable limiting groove 13a.

[0055] In this embodiment, the first guide portion 131 is provided with two movable limit grooves 13a, and the two movable limit grooves 13a are arranged at intervals along the length extension direction of the first guide portion 131. At the same time, the first guide groove 40a is provided with two limit columns 403, and each limit column 403 is located in a movable limit groove 13a. When the motor 20 rotates, as the push rod 40 moves back and forth, each limit column 403 can abut the groove walls at both ends of a movable limit groove 13a, thereby realizing the limited movement of the push rod 40.

[0056] In one embodiment, if Figures 6 to 9 As shown, the shell 10 includes an upper shell 11 and a lower shell 12, the upper shell 11 is connected to the lower shell 12 and encloses an installation space 10a, the motor 20 and the transmission assembly 30 are fixedly arranged in the installation space 10a, and the push rod 40 is movably arranged in the installation space 10a; a first bearing portion 111 is provided on the side of the upper shell 11 facing the lower shell 12, and the first bearing portion 111 and the upper shell 11 enclose a bearing space 11a connected to the installation space 10a; a notch groove 12a is provided on the outer wall of the lower shell 12, and part of the structure of the push rod 40 is arranged in the bearing space 11a and the notch groove 12a.

[0057] In this embodiment, the housing 10 is composed of an upper housing 11 and a lower housing 12 to form a box-shaped structure. The upper housing 11 can be fixedly connected to the lower housing 12 by bolts, screws and other locking members to enclose and form an installation space 10a. The motor 20 and the transmission assembly 30 are fixedly arranged in the installation space 10a, and the push rod 40 is movably arranged in the installation space 10a to protect the motor 20 and the transmission assembly 30 and reduce noise transmission. In order to further increase the installation space 10a of the housing 10, a first bearing portion 111 is provided on one side of the upper housing 11 facing the lower housing 12. The first bearing portion 111 is a portion of the upper housing 11 protruding from the lower housing 12. The first bearing portion 111 is located in the installation space 10a. The first bearing portion 111 and the upper shell 11 are enclosed to form a bearing space 11a connected to the installation space 10a. At the same time, a notch groove 12a is provided on the outer wall of the lower shell 12. The notch groove 12a and the bearing space 11a are located at the same height relative to the inner bottom wall of the lower shell 12. Part of the structure of the push rod 40 is arranged in the bearing space 11a and the notch groove 12a, so that a certain gap is formed between the bottom of the push rod 40 and the transmission assembly 30, thereby preventing the non-meshing rack structure of the push rod 40 from contacting the transmission assembly 30 and thus avoiding additional mechanical wear.

[0058] In one embodiment, if Figure 7 and Figure 8As shown, the upper shell 11 is further provided with a second limiting portion 112 on one side facing the lower shell 12, the second limiting portion 112 is connected to the first bearing portion 111, and is aligned with the notch groove 12a; the push rod 40 is provided with a limiting arm 402 on one side of the meshing rack 401, and the limiting arm 402 is located on the side of the meshing rack 401 close to the notch groove 12a;

[0059] When the motor 20 is running, the limiting arm 402 can abut against the lower shell 12 , or the second limiting portion 112 can stop the end of the limiting push rod 40 away from the notch groove 12 a .

[0060] In this embodiment, a second limiting portion 112 is further provided on the side of the upper shell 11 facing the lower shell 12. The second limiting portion 112 is a convex structure protruding from the upper shell 11 toward the lower shell 12. The second limiting portion 112 and the first bearing portion 111 are an integral structure. The second limiting portion 112 is aligned with the notch groove 12a. Furthermore, a limiting arm 402 is provided on one side of the engaging rack 401 of the push rod 40. The limiting arm 402 is located on the side of the engaging rack 401 close to the notch groove 12a. In this way, when the motor 20 rotates forward or reversely, the limiting arm 402 can abut the lower shell 12, or the second limiting portion 112 stops the end of the limit push rod 40 away from the notch groove 12a to limit the maximum movement stroke of the push rod 40.

[0061] In one embodiment, if Figure 7 and Figure 8 As shown, a first limiting groove 12b is provided on one side of the lower shell 12 facing the upper shell 11, and a second limiting groove 11b is provided on one side of the upper shell 11 facing the lower shell 12, and the motor 20 is clamped in the first limiting groove 12b and the second limiting groove 11b.
