Description

Technical Field

[0001] This utility model belongs to the field of stationery box technology, and in particular relates to a multifunctional stationery box with fingerprint unlocking. Background Technology

[0002] With the increasing awareness of students' personal belongings management in primary and secondary school education, and the penetration of smart hardware technology into the portable stationery field, traditional pencil cases have gradually become unable to meet users' dual needs for item security and functional integration. Pencil cases with fingerprint unlocking function have emerged as a result.

[0003] For example, utility model patent application number 202222724155.2 discloses a fingerprint unlocking pencil case, which includes a pencil case body and a fingerprint lock structure disposed on the pencil case body. The fingerprint lock structure is used to lock the lid of the pencil case body to the body. The fingerprint lock structure includes a locking fastener and a locking tongue assembly that can be locked together, a drive assembly connected to the locking tongue assembly, and a fingerprint control assembly electrically connected to the drive assembly. The drive assembly can drive the locking tongue assembly to release the locking fastener so that the lid can be opened from the body.

[0004] However, this technology uses a single fingerprint for unlocking, which has a low fault tolerance rate. Recognition may fail when the finger is wet, damaged, or the fingerprint is faint, making it impossible to unlock the pencil case promptly. Furthermore, the fingerprint lock structure of the aforementioned fingerprint-unlocked pencil case uses a motor to drive a cam, which in turn pushes the latch. The latch can only move in the direction of the cam's rotation, and it is perpendicular to the motor's output shaft. This fingerprint lock structure occupies a large vertical storage space, making it difficult to utilize the horizontal storage space on either side of the fingerprint lock structure inside the pencil case. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional pencil case with fingerprint unlocking, which aims to solve the problems of low fault tolerance and poor space utilization in existing fingerprint unlocking pencil cases.

[0006] To achieve the above objectives, this utility model provides a multifunctional pencil case with fingerprint unlocking, comprising a pencil case body. The pencil case body includes an upper shell and a lower shell connected by a connecting shaft. The upper shell and the lower shell together form a receiving cavity. The upper shell integrally extends into the receiving cavity to form a first mounting cavity, and the lower shell integrally extends into the receiving cavity to form a second mounting cavity. A locking hook is provided in the second mounting cavity, and the locking hook extends upward into the first mounting cavity. A locking tongue is provided in the first mounting cavity to lock with the locking hook. A groove is provided at the top of the locking tongue, and a power shaft is provided above the groove. One side of the power shaft is fixed... A micro motor is fixedly connected to drive the power shaft to rotate. A push ring is sleeved on the outer periphery of the power shaft. The inner surface of the push ring has a first rib structure that extends continuously in a spiral. The circumferential side of the power shaft has a second rib structure that matches the first rib structure. A push rod extends downward from the push ring and extends into the groove. The first rib structure and the second rib structure engage. When the micro motor drives the power shaft to rotate forward or backward, the second rib structure squeezes the first rib structure, causing the push ring, the push rod, and the locking tongue to move along the axial direction of the power shaft, and the locking tongue disengages from the locking hook. The micro motor is electrically connected to an unlocking control circuit board, which includes a fingerprint input module, a password input module, and a main control module, wherein: The fingerprint input module is used to collect the user's fingerprint information; the password input module is used to collect the password information entered by the user. The main control module is electrically connected to the fingerprint input module and the password input module respectively, and is used to verify whether the fingerprint information and the password information are correct. The main control module is connected to the micro motor and is used to control the operation of the micro motor.

[0007] As an optional solution of this utility model, the unlocking control circuit board further includes a Bluetooth module, which is used to establish a wireless communication channel with the mobile phone APP and receive control commands sent by the mobile phone APP.

[0008] As an optional solution of this utility model, a miniature battery is provided on the other side of the power shaft to provide a stable power supply for the unlocking control circuit board and the miniature motor.

[0009] As an optional embodiment of this utility model, at least two rotating plates are connected to both ends of the connecting shaft. The first rotating plate covers the edge of the upper housing. When the first rotating plate is rotated downward along the connecting shaft, the first rotating plate separates from the edge of the upper housing, opening the receiving cavity of the upper housing. The second rotating plate covers the edge of the lower housing. When the second rotating plate is rotated upward along the connecting shaft, the second rotating plate separates from the edge of the lower housing, opening the receiving cavity of the lower housing.

[0010] As an optional solution of this utility model, the front sides of both the first rotating plate and the second rotating plate are provided with a pen mark layer for repeated erasing.

[0011] As an optional solution of this utility model, the back of both the first rotating plate and the second rotating plate are provided with a fitting groove for accommodating a detachable small mirror and a detachable calculator.

[0012] As an optional solution of this utility model, the control commands include new fingerprint enrollment commands, old fingerprint deletion commands, password modification commands, and mode switching commands.

[0013] As an optional solution of this utility model, the mode switching command includes a compatibility mode and a security mode, wherein: When the main control module is in the compatibility mode, if the fingerprint information or the password information is correct, it controls the micro motor to operate and unlock. When the main control module is in the compatibility mode, if both the fingerprint information and the password information are correct, it controls the micro motor to operate and unlock.

[0014] As an optional solution of this utility model, the upper housing is provided with a cover plate for closing the first mounting cavity. The cover plate is provided with several through holes, through which the fingerprint input module and the password input module extend out of the first mounting cavity to facilitate the collection of the fingerprint information and the password information.

[0015] The multifunctional pencil case with fingerprint unlocking provided in this embodiment of the utility model has at least one of the following technical effects: This application provides a multi-functional pencil case with fingerprint unlocking. By incorporating an unlocking control circuit board including a fingerprint input module, a password input module, and a main control module, the operation of a micro-motor is controlled. A compatibility mode that unlocks with only correct fingerprint or password information improves the pencil case's fault tolerance. A security mode requiring both correct fingerprint and password information further enhances the pencil case's security. By incorporating two rotating plates that can seal the upper and lower shells, the internal cavity of the pencil case is divided into two chambers for separate storage of stationery, overcoming the limitation of traditional pencil cases that can only utilize storage space on one side. A pen layer on the rotating plates enables the pencil case to function as erasable draft paper. An insert groove on the rotating plates allows the pencil case to accommodate detachable mirrors, calculators, and other flat-structured tools with minimal space requirements. By extending mounting cavities into the upper and lower housings, and using a micro-motor to drive a rotating shaft within these cavities, the rotating shaft, through a rib structure, compresses and moves the push ring, push rod, and latch along its axial direction, thus disengaging the latch from the hook. In this implementation, the latch moves along the axial direction of the rotating shaft, allowing the micro-motor and latch to be arranged laterally, reducing the vertical space occupied by the unlocking components and increasing the usable storage space within the pencil case.

[0030] In specific embodiments of this utility model, such as Figure 1 As shown, a multifunctional pencil case with fingerprint unlocking is provided, including a pencil case body. The pencil case body includes an upper shell 1 and a lower shell 2 connected by a connecting pivot. The upper shell 1 and the lower shell 2 together form a receiving cavity. The upper shell 1 extends integrally into the receiving cavity and is provided with a first mounting cavity 101. The lower shell 2 extends integrally into the receiving cavity and is provided with a second mounting cavity 201. An unlocking device 4 is provided between the first mounting cavity 101 and the second mounting cavity 201. A first rotating plate 301 and a second rotating plate 302 are provided between the upper shell 1 and the lower shell 2.

[0031] Reference Figure 1 , Figure 2a and Figure 2b The lower housing 2 has a first connecting bushing 203 at the center of its edge, and the upper housing 1 has a second connecting bushing 107 on both sides of its edge. The second connecting bushing 107 and the first connecting bushing 203 are connected sequentially by a connecting shaft.

[0032] Reference Figure 1 , Figure 2a and Figure 2b The second mounting cavity 201 has first limiting posts 204 on both sides, and a locking hook 202 between the two first limiting posts 204. The bottom of the first mounting cavity 101 has first limiting through holes 102 on both sides. The first limiting posts 204 extend into the first mounting cavity 101 through the first limiting through holes 102, used to calibrate the positions of the first and second mounting cavities 101 when the upper and lower shells are closed. A locking hook through hole 103 is provided in the center of the two first limiting through holes 102. The locking hook 202 extends into the first mounting cavity 101 through the locking hook through hole 103, locking with the unlocking device 4. The second mounting cavity 201 has a connecting post 104 and a limiting groove 105 for limiting and fixing the unlocking device 4.

[0033] Reference Figure 3a and Figure 3b A first rotating plate 301 covers the edge of the upper housing 1, and a second rotating plate 302 covers the edge of the lower housing 2. Both sides of the first rotating plate 301 and the second rotating plate 302 are provided with third connecting bushings 305. A connecting shaft passes through the third connecting bushings 305, allowing the first rotating plate 301 and the second rotating plate 302 to rotate up and down along the connecting shaft. A lifting hole 304 is provided at any corner of the first rotating plate 301 and the second rotating plate 302. When a user inserts a finger through the lifting hole 304 and rotates the first rotating plate 301 downwards along the connecting shaft, the first rotating plate 301 separates from the edge of the upper housing 1, opening the receiving cavity of the upper housing 1. When the second rotating plate 302 is rotated upwards along the connecting shaft, the second rotating plate 302 separates from the edge of the lower housing 2, opening the receiving cavity of the lower housing 2.

[0034] Preferred, refer to Figure 3a and Figure 3b An anti-air groove 303 is provided at the edge of the first rotating plate 301 and the second rotating plate 302 for the anti-air unlocking device 4.

[0035] Preferred, refer to Figure 3a and Figure 3b The front of both the first rotating plate 301 and the second rotating plate 302 is provided with a pen mark layer 306 for repeated erasing and writing, which allows users to record and make draft calculations, so that the pencil case has the function of repeatedly erasable draft paper.

[0036] Preferred, refer to Figure 3a and Figure 3b The back of the first rotating plate 301 and the second rotating plate 302 are both provided with a fitting groove 307. The tool is gradually pushed into the bottom of the fitting groove 307 along the opening of the fitting groove 307, so that the pencil case can carry detachable mirrors, calculators and other flat tools with minimal space cost.

[0037] Reference Figure 4a The unlocking device 4 includes a fixed housing 401. The front surface of the fixed housing 401 is fixed with an unlocking control circuit board 403 and a USB-C interface 404. The rear surface of the fixed housing 401 and the first mounting cavity 101 are jointly fixed with a micro battery 405, an unlocking component 407 and a spring buffer column 406. The buffer opening of the spring buffer column 406 faces downward and extends out of the first mounting cavity 101. When the upper housing 1 and the lower housing 2 are closed, the buffer head of the spring buffer column 406 abuts against the edge of the lower housing 2. The buffer head contracts inward to compress the spring, reducing the stress generated when the upper and lower housings are closed, so as to reduce the wear of the edges of the upper and lower housings.

[0038] Reference Figure 2a The first mounting cavity is also provided with a USB-C through hole 106. The USB-C interface 404 extends upward along the USB-C through hole 106 and is connected to an external power source to provide power input for the battery 405 and the unlocking control circuit board 403.

[0039] Reference Figure 4bThe unlocking component 407 includes a latch 4079 that engages with the latch 202. The top of the latch 4079 has a groove 40710. Above the groove 40710, a power shaft 4073 is provided. The side of the power shaft has a cross groove 4074. A micro motor 4071 is connected to the cross groove 4074. A motor output shaft 4072 is provided on one side of the micro motor 4071. The motor output shaft 4072 is cross-shaped and matches the cross groove 4074. When the motor output shaft 4072 rotates, it drives the power shaft 4073 to rotate. A push ring 4075 is fitted around the outer periphery of the power shaft 4073. The inner surface of the push ring 4075 has a first rib structure 4076 that extends continuously in a spiral. The peripheral side of the power shaft 4073 has a second rib structure 4077 that matches the first rib structure 4076. The first rib structure 4076 and the second rib structure 4077 mesh. When the micro motor 4071 drives the power shaft 4073 to rotate forward or backward, the second rib structure 4077 and the first rib structure 4076 fit tightly together, driving the push ring 4075 to rotate. A push rod 4078 extends downward from the push ring 4075. The push rod 4078 extends into the groove 40710. The push rod 4078 rotates along with the push ring 4075, but due to the limiting obstruction of the fixed housing 401, the push rod 4078 cannot continue to rotate after rotating into the groove 40710. At this time, the micro motor 4071 continues to rotate forward or in reverse. The second rib structure 4077 begins to squeeze the first rib structure 4076. Under the squeezing force of the second rib structure 4077, the first rib structure 4076, the push ring 4075, and the push rod 4078 move along the axial direction of the power shaft 4073. The push rod 4078 cooperates with the groove 40710, driving the locking tongue 4079 to move along the axial direction of the power shaft 4073, so that the locking tongue 4079 disengages from the locking hook 202.

[0040] Preferred, refer to Figure 4b On the other side of the micro motor 4071, there is a motor control pole 40711, which is connected to the unlocking control circuit board 403 to control the operation of the micro motor 4071.

[0041] Preferred, refer to Figure 4b The power shaft 4073 is also fitted with a limiting ring 40712, which is located on one side of the push ring 4075 to prevent the push ring 4075 from disengaging from the power shaft 4073 when it moves along the axial direction of the power shaft 4073.

[0042] Preferred, refer to Figure 4bA spring return post 40713 is provided on one side of the locking tongue 4079. The buffer head of the spring return post 40713 abuts against the first mounting cavity 101. The locking tongue 4079 presses the buffer head of the spring return post 40713 along the axial direction of the power shaft 4073. The buffer head retracts inward to compress the spring, thereby displacing the locking tongue 4079. When the power of the micro motor 4071 is lost, the spring return post 40713 expands outward, causing the locking tongue 4079 to return to its original position.

[0043] Preferred, refer to Figure 4b The bottom of the locking tongue 4079 is provided with an arc-shaped inclined surface 40714. When the upper housing 1 and the lower housing 2 are closed, the locking hook 202 abuts against the arc-shaped inclined surface 40714 and applies a lateral pressing force to the arc-shaped inclined surface 40714. The locking tongue 4079 is subjected to the pressing force, which compresses the spring return post 40713 and moves horizontally until the locking hook 202 extends into the first mounting cavity 101. The pressing force disappears, and the locking tongue 4079 locks with the locking hook 202 under the action of compressing the spring return post 40713, thereby realizing the locking of the pencil case. When the micro motor 4071 drives the power shaft 4073 to rotate forward or in reverse, under the combined action of the second rib structure 4077, the first rib structure 4076, the push ring 4075, the push rod 4078 and the groove 40710, the locking tongue 4079 presses the spring return post 40713 and moves horizontally, so that the locking tongue 4079 disengages from the locking hook 202, thereby unlocking the pencil case.
