[0031] Example 1

[0032] This embodiment provides a card receiving and sending mechanism (hereinafter referred to as the card receiving and sending mechanism) for an automatic card receiving and sending charging cabinet, which is used to insert a positioning card. In a specific implementation scenario, the card receiving and sending mechanism is installed in the charging cabinet, which is used to charge and store the positioning card. The charging cabinet is typically equipped with multiple card receiving and sending mechanisms, each of which is suitable for inserting a positioning card and electrically connecting to the positioning card.

[0033] Figure 1 This is a schematic diagram of the three-dimensional structure of the card receiving and sending mechanism and the positioning card of the automatic card receiving and sending charging cabinet provided by the embodiment of the utility model. Figure 2 This is a schematic diagram of the three-dimensional structure of the card receiving and sending mechanism provided by the embodiment of the utility model with a positioning card inserted. Figure 3 This is a cross-sectional structural diagram of the card receiving and sending mechanism provided by the embodiment of the present utility model. Figure 1 、 Figure 2 and Figure 3 The card receiving and sending mechanism includes a housing 10 , a pop-up mechanism 20 and a locking mechanism 30 .

[0034] A card cavity 12 for accommodating the positioning card 40 is formed inside the shell 10, and a socket 14 connected to the card cavity 12 is provided at one end of the shell 10. The shell 10 is roughly in the shape of a rectangular parallelepiped, and accordingly, the card cavity 12 is also in the shape of a rectangular parallelepiped. The card cavity 12 has a length side, a width side and a thickness side, wherein the length side is greater than the width side, and the width side is greater than the thickness side. The socket 14 is provided at one end defined by the width side and the thickness side of the card cavity 12. The plane passing through the center of the card cavity 12 and parallel to the length side and the width side is the extension plane of the card cavity 12. The shell 10 includes a first side wall 13 and a second side wall 15 parallel to the extension plane of the card cavity 12. The first side wall 13 and the second side wall 15 are arranged opposite to each other.

[0035] The ejection mechanism 20 is provided in the housing 10 and is used to apply a force to the positioning card 40 to withdraw from the card cavity 12. The ejection mechanism 20 is arranged opposite to the socket 14. Specifically, the ejection mechanism 20 includes a push rod 21 and an elastic member (not shown) that abuts against the push rod 21. The housing 10 includes an opening provided on the bottom wall of the card cavity 12, the opening is arranged opposite to the socket 14, and the push rod 21 is inserted into the opening. When the card cavity 12 does not have the positioning card 40 inserted, the push rod 21 is in an extended position extending into the card cavity 12 under the action of the elastic member. When the positioning card 40 is inserted, the end face of the positioning card 40 presses against the push rod 21, causing the push rod 21 to partially withdraw from the card cavity 12 relative to the extended position. The elastic member is compressed, thereby allowing the push rod 21 to maintain the force pushing against the positioning card 40.

[0036] Specifically, the push rod 21 is hollow, with an elastic member disposed within it. The ejection mechanism 20 also includes a base, with one end of the elastic member abutting the base and the other end abutting the inner wall of the push rod 21. This allows the push rod 21 to move relative to the base, overcoming the elastic force of the elastic member. The base also includes a positioning rod 25, which extends through the push rod 21 and is sleeved around the elastic member. The positioning rod 25 is used to position the push rod 21 and guide its movement.

[0037] The locking mechanism 30 is used to lock the positioning card 40 within the card cavity 12. Specifically, the locking mechanism 30 is disposed on the housing 10 and includes a locking member 32 and an actuating member 31. The actuating member 31 is in transmission connection with the locking member 32. The locking member 32 has a locked state and an unlocked state. The actuating member 31 is used to drive the locking member 32 to switch from the locked state to the unlocked state.

[0038] Specifically, the locking member 32 includes a locking tongue 321. The housing 10 defines a through-hole in the first side wall 13, and the locking tongue 321 extends through the through-hole. When the locking member 32 is locked, the locking tongue 321 is in a locked position, extending into the card cavity 12. When the locking member 32 is unlocked, the locking tongue 321 is in an unlocked position, partially withdrawn from the card cavity 12 relative to the locked position. The actuator 31 is configured to drive the locking tongue 321 from the locked position to the unlocked position. The locking tongue 321 has a guide surface s disposed toward the socket 14. The guide surface s extends obliquely from the end of the locking tongue toward the side proximal to the socket 14. In response to insertion of the positioning card 40, the locking tongue 321 moves toward the unlocked position and automatically engages with the groove 41 of the positioning card 40, abutting against the sidewalls of the groove 41. The locking tongue 321 faces the ejection mechanism 20, preventing the positioning card 40 from being ejected outward by the ejection mechanism 20. The groove 41 of the positioning card 40 is for inserting an employee information card. In this way, the positioning card 40 is locked in the card cavity 12 by the locking tongue 321 .

[0039] The card receiving and sending mechanism provided in this embodiment has a through-hole disposed on a first side wall of the housing, parallel to the extended surface of the card cavity. The locking tongue of the locking mechanism is disposed through the through-hole. The locking tongue has an inclined guide surface disposed toward the socket. In response to the insertion of the positioning card, the locking tongue moves toward the card cavity and automatically engages with the positioning card's groove, abutting against the side wall of the groove. The positioning card's groove is used to insert the employee information card. This automatically locks the positioning card during insertion. The positioning groove uses the existing employee information card's groove, eliminating the need to modify the positioning card's structure. Charging cabinets using this card receiving and sending mechanism can adapt to existing employee positioning cards, providing excellent versatility.

[0040] In order to ensure the locking reliability of the positioning card, in the specific embodiment, please refer to Figure 3 As shown, the lock tongue 321 moves linearly between the locked position and the unlocked position in a direction perpendicular to the first side wall 13. As such, the movement path of the lock tongue 321 is perpendicular to the direction of force applied by the ejection mechanism 20 for ejecting the positioning card 40. The elastic force of the ejection mechanism substantially does not affect the unlocking and locking of the lock tongue, thereby ensuring the reliability and life of the locking mechanism.

[0041] Figure 4 The three-dimensional structure diagram of the locking member 32 in the locked position is shown. Figure 3 and Figure 4As shown, the actuating member 31 includes a motor 311 and an eccentric member 313 disposed on the rotating shaft of the motor 311. The eccentric member 313 is in transmission connection with the locking member 32. The motor 311 drives the eccentric member 313 to rotate. The eccentric end of the eccentric member 313 pushes against the locking member 32, thereby driving the lock tongue 321 to move from the locked position to the unlocked position. Specifically, the eccentric end of the eccentric member 313 extends in the radial direction away from the rotating shaft of the motor 311. In the circumferential direction, the distance between the eccentric end of the eccentric member 313 and the rotating shaft of the motor 311 is the largest. When the locking member 32 is in Figure 4 In the locked position shown, the eccentric end of the eccentric piece 313 is disengaged from the inner wall of the locking piece 32. When the eccentric piece 313 is driven to rotate by the motor 311, the eccentric end of the eccentric piece 313 rotates to a position that pushes upward against the locking piece 32, causing the locking tongue 321 to move upward and exit the through hole. The locking tongue 321 is disengaged from the positioning card 40, and the positioning card 40 automatically pops out of the card cavity 12 under the elastic force of the pop-up mechanism 20.

[0042] In the specific embodiment, please combine Figure 2 and Figure 4 The locking mechanism 30 further includes a housing 33 and a guide groove 331 provided on the housing 33. The locking member 32 includes a protrusion 323 that slides in cooperation with the guide groove 331. The protrusion 323 extends into the guide groove 331 and can slide along the length direction of the guide groove 331. The guide groove 331 extends in a direction perpendicular to the first side wall 13 and is used to guide the locking member 32 to move from the locked position to the unlocked position along a straight line. Preferably, the guide groove 331 and the protrusion 323 are provided in pairs, and a guide groove 331 is provided on each of the two opposite side walls of the housing 33. Correspondingly, two protrusions 323 are provided at corresponding positions of the locking member 32. The two protrusions 323 are respectively embedded in the guide groove 331 and slide in cooperation with the side walls of the guide groove 331 to guide the movement direction of the locking member 32.

[0043] In order to make the locking member automatically return to the locked position more reliably, in one embodiment, the locking mechanism 30 also includes a return spring 35, which is located in the shell 33. One end of the return spring 35 abuts against the locking member 32, and the other end abuts against the inner wall of the shell 33, and is used to apply an elastic force to the locking member 33 to move toward the locked position, so that the locking member automatically returns to the locked position.

[0044] A charging connector is also provided at the bottom of the card transceiver mechanism for docking with the positioning card to charge it. Those skilled in the art are aware that the positioning card releases a significant amount of heat during charging. If not dissipated promptly, this may damage the internal components of the positioning card. To help the positioning card dissipate heat, in one embodiment, the housing 10 includes a rib 17 disposed within the card cavity 12 for guiding and supporting the positioning card 40. The rib 17 protrudes from the first side wall 13 and the second side wall 15. The rib 17 is disposed parallel to the insertion direction of the positioning card 40, and adjacent ribs 17 are spaced apart to form heat dissipation gaps. Thus, after insertion, the positioning card 40 is supported and positioned between the ribs 17 of the first side wall 13 and the second side wall 15. Both surfaces of the positioning card 40 have multiple heat dissipation gaps, which improves the heat dissipation effect of the positioning card 40. Furthermore, the rib 17 can also guide the insertion path of the positioning card 40, ensuring accurate docking of the positioning card 40 with the charging connector.

[0045] In order to achieve dustproofing of the card receiving and sending mechanism, in one embodiment, the card receiving and sending mechanism further comprises a baffle mechanism 50 provided on the housing 10. The baffle mechanism 50 is located at the socket 14 and is used to close the socket 14 when the positioning card is not inserted. The baffle mechanism 50 comprises a rotating shaft 54, a baffle 51 pivoted around the rotating shaft 54, and a torsion spring 53 sleeved on the rotating shaft 54. The baffle 51 has a closed state (e.g., Figure 1 and Figure 3 As shown) and the open state of the opening 14 (as shown Figure 2 As shown), the baffle 51 can rotate from the open state to the closed state under the action of the torsion spring 53, thereby automatically closing the socket 14.

[0046] In other embodiments, the actuating member is implemented using an electromagnetic device. Specifically, the actuating member includes an electromagnet, the locking member includes a magnetic member, the lock tongue is fixedly connected to the magnetic member, and the electromagnet is surrounded by an electromagnetic coil. When the electromagnetic coil is energized, the electromagnet is magnetized and becomes magnetic. The magnetic member drives the lock tongue to move under the magnetic effect of the electromagnet, thereby attracting the lock tongue to the unlocked position.

[0048] The present invention also provides a charging cabinet including the card receiving and sending mechanism described in any of the above embodiments. The number of card receiving and sending mechanisms in the charging cabinet is not limited. The structural implementation of the card receiving and sending mechanisms can be found in Example 1 and will not be further described here.

[0049] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative work, which should fall within the scope of protection of the present invention.
