Technical Field
[0001] This utility model relates to the field of backpack technology, specifically to a fingerprint anti-theft component and a backpack. Background Technology
[0002] Backpacks are widely used in daily life, and people often use them when traveling for business or leisure. For travelers, the security and privacy of their belongings are key concerns, especially valuable items such as laptops and important contract documents. However, the fingerprint anti-theft function of existing smart backpacks is not reliable enough. For example, some solutions rely on a single motor to drive the locking tongue, which is prone to failure due to circuit failure, external impact, or insufficient motor torque, resulting in locking failure, unlocking failure, or even brute-force cracking.
[0003] For example, publication number CN208236167U discloses a smart backpack with fingerprint anti-theft function, including a backpack body, a zipper, and a zipper pull. The zipper is located on the backpack body, and the zipper pull is provided on the zipper. It also includes a fingerprint lock body, a fingerprint lock latch, a fingerprint reader, a fingerprint lock charging port, and fingerprint lock function buttons. The fingerprint lock body is located on the backpack body, with a fingerprint reader on the front and a fingerprint lock latch, fingerprint lock pull, charging port, and function buttons on the side. The fingerprint lock body contains a battery for powering the fingerprint lock, an electronic mainboard, and a motor drive device. The electronic mainboard is signal-connected to the fingerprint reader, function buttons, and motor drive device. This utility model avoids the problems of traditional password anti-theft backpacks, which rely on passwords for unlocking and are easily forgotten or cracked.
[0004] However, in outdoor environments with severe vibrations or bumps, relying solely on the latch structure for anti-theft may lead to latch failure or unlocking malfunction due to circuit vibration or external impact. Furthermore, the latching force between the latch and the zipper depends primarily on the motor torque. When the zipper is forcibly pulled by external force, insufficient motor torque can easily cause latch deformation or motor gear slippage, posing a security risk of being forcibly broken. The overall anti-theft strength is relatively weak. Therefore, those skilled in the art provide a smart backpack with fingerprint anti-theft functionality to solve the problems mentioned in the background. Utility Model Content

Detailed Implementation
[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Please see Figures 1-4As shown, this utility model provides a technical solution: a fingerprint anti-theft component and a backpack, including a fingerprint control mechanism 4 for anti-theft. The fingerprint control mechanism 4 includes a base 41, an upper plate 42 fixedly connected to the top of the base 41, a sensor 43 fixedly connected to the bottom of the upper plate 42, a fingerprint groove 412 opened in the inner cavity of the upper plate 42, and the fingerprint groove 412 is located at the bottom of the sensor 43. The fingerprint groove 412 and the sensor 43 are electrically connected, and the fingerprint groove 412 is used to input fingerprint information.
[0022] When a finger is pressed on the fingerprint groove 412, the raised and recessed patterns of the fingerprint will cause different electrical signal changes in the sensor 43 at the bottom of the fingerprint groove 412. The sensor 43 converts these changes into electrical signals and transmits them to the control component 44 for processing in a timely manner through electrical connection.
[0023] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, a control component 44 is fixedly connected to one end of the sensor 43. The control component 44 includes a receiving module, a processing module, and an output module. The receiving module receives the raw detection signal output by the sensor 43.
[0024] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the processing module is electrically connected to the receiving module, and performs analog-to-digital conversion, filtering and feature extraction on the original detection signal. The output module is electrically connected to the processing module, and converts the processed feature parameters into a standard communication protocol format and outputs them.
[0025] The receiving module receives the raw analog electrical signal from the sensor 43. The processing module first performs analog-to-digital conversion on the signal to convert it into a digital signal for computer processing. Then, it performs filtering to eliminate interference and noise in the signal. Finally, it performs feature extraction to extract fingerprint feature points from the digital signal, such as the start point, end point, and bifurcation point of the ridge. The output module converts these feature parameters into a standard communication protocol format and outputs them to the cylinder 45.
[0026] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, a cylinder 45 is fixedly connected to one end of the control component 44 away from the sensor 43, a piston rod 46 is fixedly connected to one end of the cylinder 45, and a telescopic rod 47 is slidably connected to the inner cavity of the piston rod 46.
[0027] The signal output by the control component 44 controls the working state of the cylinder 45. The cylinder 45 is a single-acting cylinder. When compressed gas is introduced into the cylinder 45, the gas pressure pushes the piston rod 46 to move. The piston rod 46 drives the telescopic rod 47 to slide outward in its inner cavity. When the gas is discharged from the cylinder 45, the piston rod 46 and the telescopic rod 47 retract inward under the action of the spring 411. For example, in the normal state, the cylinder 45 provides a pushing force to the latching module 410, so that the latching module 410 locks the zipper 3. When the fingerprint recognition is successful, the cylinder 45 reacts to the piston rod 46, which drives the telescopic rod 47 to extend and retract to one side of the cylinder 45, thereby pulling the latching module 410 and releasing the lock on the zipper 3. Thus, the backpack can be opened through the zipper 3, thereby realizing the fingerprint anti-theft function.
[0028] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, a battery receiving part is fixedly provided in the inner cavity of the bottom wall of the upper plate 42. The battery receiving part includes a battery pack 48 and a charging slot 413. The battery pack 48 is fixedly connected to the bottom end of the upper plate 42.
[0029] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the charging slot 413 is formed in the bottom wall of the inner cavity of the upper plate 42, and the electrodes of the battery pack 48 are electrically connected to the conductive contacts of the charging slot 413.
[0030] The battery pack 48 stores electrical energy and delivers it to various electrical components via circuitry when the backpack is in operation. When the battery pack 48 is low on power, a charging device is inserted into the charging slot 413. The charging contacts of the charging device make contact with the conductive contacts of the charging slot 413, and electrical energy is transferred to the electrodes of the battery pack 48 through the conductive contacts to charge the battery pack 48. The electrodes of the battery pack 48 and the conductive contacts of the charging slot 413 maintain an electrical connection to ensure a smooth charging circuit.
[0031] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the inner cavity of the upper plate 42 is rotatably connected to a connecting shaft 49, and the outer side of the connecting shaft 49 is rotatably connected to a snap-fit module 410, one end of which is tightly connected to the zipper 3.
[0032] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, one end of the snap-fit module 410 is tightly connected to the zipper 3, and a spring 411 is fixedly connected to one end of the snap-fit module 410. The snap-fit module 410 is fixedly connected to the base 41 through the spring 411.
[0033] When spring 411 is in a stretched or compressed state, it causes the locking module 410 to rotate around the connecting shaft 49 through tension or thrust. Its end tightly locks the zipper head 3 or the zipper tooth chain 3, preventing the zipper 3 from sliding. At this time, there is no compressed gas in the cylinder 45, and the telescopic rod 47 is in the initial position. No external force is applied to the locking module 410. The locking module 410 is locked entirely by the force of spring 411. When fingerprint recognition is successful, the control component 44 outputs an electrical signal to drive the solenoid valve to open the air source. Compressed gas is introduced into the rodless chamber of the single-acting cylinder 45, and the gas pressure pushes the rodless valve to open the air source. The piston rod 46 drives the telescopic rod 47 to retract towards the cylinder 45. The retraction of the telescopic rod 47 causes the locking module 410 to rotate in the opposite direction around the connecting shaft 49, overcoming the force of the spring 411 and causing the end of the locking module 410 to separate from the zipper 3, thus releasing the lock. At this time, the user can pull the zipper 3 normally to open the backpack. When the backpack is closed and the fingerprint recognition system does not receive an unlock signal, the gas in the cylinder 45 is discharged, and the piston rod 46 and the telescopic rod 47 extend outward under the action of the spring 411's restoring force, pushing the locking module 410 to lock the zipper 3 along the connecting shaft 49.
[0034] The backpack, including the backpack body 1 and the aforementioned fingerprint anti-theft component, please refer to [link / reference]. Figures 1-2 As shown, a shoulder strap 2 for carrying is fixedly connected to one end of the backpack body 1. An opening is provided in the inner cavity of the backpack body 1. A zipper 3 for opening and closing is fixedly connected to the edge of the opening by a sewing thread. A Bluetooth connection slot 5 for Bluetooth connection is fixedly connected to the inner cavity of the backpack body 1.
[0035] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the Bluetooth connection slot 5 is used to establish a Bluetooth connection with an external device. The Bluetooth connection slot 5 is electrically connected to the control component 44 and can transmit the fingerprint information processed by the control component 44 to the external device, or receive control commands sent by the external device to control the working state of the cylinder 45.
[0036] Users input their fingerprints through the fingerprint slot 412, the shoulder strap 2 is used to carry the backpack on their body for easy carrying, the zipper 3 is used to open or close the backpack opening to access items, and the Bluetooth connection slot 5 can establish a Bluetooth connection with external devices such as mobile phones, which may be used to transmit fingerprint data, receive control commands or send alarm information, etc. It integrates traditional loading and carrying functions with intelligent anti-theft and Bluetooth connection functions to meet the diverse needs of users.
[0037] Working principle: The user inputs their fingerprint through the fingerprint slot 412. The sensor 43 converts the fingerprint information into an electrical signal. After processing by the receiving module, processing module, and output module of the control component 44, a signal in a standard communication protocol format is output to control the cylinder 45. During this process, the spring 411 is in a stretched or compressed state, causing the locking module 410 to rotate around the connecting shaft 49 through pulling or pushing force. Its end tightly locks the zipper head 3 or the zipper tooth chain 3, preventing the zipper 3 from sliding. At this time, there is no compressed gas in the cylinder 45, and the telescopic rod 47 is in the initial position, without applying external force to the locking module 410. The locking module 410 is locked entirely by the force of the spring 411. When the fingerprint recognition is successful, the control component 44 outputs an electrical signal to drive the solenoid valve to open the air source, and compressed gas is introduced into the rodless chamber of the single-acting cylinder 45. Gas pressure pushes piston rod 46, causing telescopic rod 47 to retract towards cylinder 45. The retraction of telescopic rod 47 causes locking module 410 to rotate in the opposite direction around connecting shaft 49, overcoming the force of spring 411 and causing the end of locking module 410 to separate from zipper 3, thus unlocking it. At this time, the user can pull zipper 3 normally to open the backpack. When the backpack is closed and the fingerprint recognition system does not receive an unlock signal, the gas in cylinder 45 is discharged, and piston rod 46 and telescopic rod 47 extend outward under the restoring force of spring 411, pushing locking module 410 along connecting shaft 49 to lock zipper 3. Single-acting cylinder 45 drives piston rod 46 and telescopic rod 47 to move by introducing or discharging compressed gas, thereby pulling or pushing locking module 410 to lock and unlock zipper 3, thus realizing fingerprint anti-theft function.
[0038] The backpack body 1 has shoulder straps 2 for carrying on the back, zippers 3 for opening and closing, Bluetooth connection slots 5 for connecting to external devices via Bluetooth, and battery pack 48 for powering various electronic components after being charged through charging slots 413. The entire system works together to meet the user's needs for backpack loading, anti-theft, and smart connectivity.
[0039] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
