Description

Technical Field

[0001] This utility model relates to the technical field of strapping devices for reinforcing suitcases. Background Technology

[0002] When traveling, people often tie a strap to the outside of their suitcases or bags to reinforce them and prevent them from bursting open. For added protection, some straps even have combination locks; the correct code is required to detach the clip from the socket. Since existing straps lack anti-loss alerts, people typically place Bluetooth GPS trackers or similar devices inside their suitcases or bags to prevent loss or misplacement. However, placing these trackers inside not only interferes with signal transmission to the user's smart device but is also small and easily lost. Utility Model Content

[0003] In summary, the purpose of this utility model is to address the aforementioned technical shortcomings of existing straps and to propose a luggage strap device based on Bluetooth positioning.

[0004] To address the technical shortcomings of this utility model, the following technical solution is adopted:

[0005] A luggage strap device based on Bluetooth positioning includes a strap body, with a buckle connector and a buckle seat at both ends of the strap body, and a combination lock mechanism on the buckle seat to prevent the buckle connector from separating and falling off the buckle seat; characterized in that: the plug end face of the buckle connector is provided with an integrally formed guide limiting block, and the buckle seat is provided with a guide slot that slides with the guide limiting block; the guide limiting block is provided with a cavity, and a Bluetooth positioning module is provided in the cavity.

[0006] The technical features that further define this utility model include:

[0007] The guide limit block has a Hall switch on its insertion end face or side for controlling the Bluetooth positioning module to turn on, and a magnetic block corresponding to the Hall switch is provided in the guide slot of the card socket.

[0008] The upper surface of the guide limiting block is provided with a sealing cover to seal the cavity; the sealing cover is connected to the guide limiting block through a detachable structure, and the Bluetooth positioning module includes a replaceable battery; both the sealing cover and the battery compartment are waterproof.

[0021] The structure of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0022] Reference Figures 1 to 4 As shown in the figure, this utility model discloses a luggage strap device based on Bluetooth positioning, including a strap body 1. Both ends of the strap body 1 are respectively provided with a snap-fit ​​connector 2 and a snap-fit ​​base 3. The snap-fit ​​base 3 is also provided with a combination lock mechanism 4 to prevent the snap-fit ​​connector 2 from separating from the snap-fit ​​base 3. The specific structure of the snap-fit ​​connection between the snap-fit ​​connector 2 and the snap-fit ​​base 3 can adopt a conventional design where the snap-fit ​​connector 2 includes a pair of elastic snap arms 21, and the ends of the elastic snap arms 21 are provided with locking heads 22. The elastic snap arms 21 deform during insertion into the snap-fit ​​base 3, and when fully inserted, the locking heads 22... Under the elastic force of the elastic locking arm 21, it locks into the locking hole 31 on the side of the locking seat 3, allowing the locking head 22 to disengage the locking connector 2 from the locking seat 3. In a conventional structure, the user can directly disengage the locking head 22 from the locking hole 31 on both sides of the locking seat 3 by pressing the locking head 22 inwards with two fingers, thus disengaging the locking connector 2 from the locking seat 3. However, this invention features a combination lock mechanism 4 between the two elastic locking arms 21, allowing for unlocking... When the combination lock mechanism 4 is in the unlocked position, the card stop head 22 needs to be moved to the unlocked position first. Then, the card stop head 22 can be pressed inward from the card holes 31 on both sides of the card holder 3 to directly disengage from the card holes 31. If the combination lock mechanism 4 is in the incorrect combination state, the combination lock mechanism 4 will prevent at least one elastic card arm 21 from deforming and unlocking under external force. That is, when the card stop head 22 is pressed, the card stop head 22 is blocked by the combination lock mechanism 4 and cannot move backward and disengage from the card hole 31.

[0023] To ensure the stable and reliable connection between the connector 2 and the base 3, and to prevent tilting that could cause the stop head 22 to accidentally fall out of the hole 31, the connector 2 has an integrally formed guide limit block 23 on its insertion end face, and the base 3 has a guide slot 33 that slides with the guide limit block 23. The guide slot 33 has a head channel 32 on each of its left and right sides for the stop head 22 to enter.

[0024] Since the widths of the connector 2 and the base 3 are determined by the width of the strap body 1, the base 3 has a relatively large space remaining after accommodating the elastic arm 21 and the stop head 22. Therefore, the guide limiting block 23 can be relatively larger than the elastic arm 21. This invention provides a cavity in the guide limiting block 23, within which a Bluetooth positioning module is housed. Integrating the Bluetooth positioning module into the cavity of the guide limiting block 23 not only does not affect the guiding and limiting effect between the guide limiting block 23 and the guide slot 33, but also provides anti-tamper locking for the Bluetooth positioning module. Without the password of the combination lock mechanism 4, the Bluetooth positioning module cannot be removed from the connector 2, thus improving the security and reliability of this invention.

[0025] In practical implementation, to improve the battery life of the Bluetooth positioning module of this invention, the insertion end face or side of the guide limiting block 23 is provided with a Hall switch 24 for controlling the opening of the Bluetooth positioning module, and a magnetic block corresponding to the Hall switch is provided in the guide slot 33 of the card holder 3. That is, when the card connector 2 and the card holder 3 are engaged in a snap-fit ​​connection, the Bluetooth positioning module is turned on and working; when the card connector 2 and the card holder 3 are separated, it represents a storage state, and there is no need to turn on Bluetooth positioning. After the Hall switch 24 loses the magnetic force of the magnetic block, the Hall switch 24 is turned off, and the Bluetooth positioning module can be turned off immediately or after a preset time. This invention controls the operation of the Bluetooth positioning module based on the snap-fit ​​connection state of the card connector 2 and the card holder 3, eliminating the need for a dedicated control switch to manually turn it on, making it convenient to use, saving unnecessary power consumption of the Bluetooth positioning module, and avoiding frequent charging.

[0026] For users who use the strap device of this utility model infrequently, to avoid discovering the Bluetooth positioning module's battery is depleted only when needed, the upper surface of the guide limiting block 23 is provided with a sealing cover to seal the cavity. The sealing cover is connected to the guide limiting block 23 via a detachable structure. The Bluetooth positioning module contains a replaceable battery. The cavity is equivalent to a battery compartment, and the sealing cover is equivalent to a compartment cover. Both the sealing cover and the battery compartment are waterproof. With the connector 2 and the connector seat 3 separated, the user can easily open the sealing cover to replace the battery. If needed, the Bluetooth positioning module can also be removed from the cavity and used as a standalone Bluetooth positioning anti-loss device.

[0027] For users who frequently use the strapping device of this utility model, the guide limiting block 23 is provided with a charging port 25, a magnetic charging terminal, or a wireless charging module for charging the Bluetooth positioning module; and the charging port is equipped with a waterproof cap. The Bluetooth positioning module can be charged by an external power source.

[0028] To immediately trigger an alarm upon abnormal separation of the card connector 2 and card holder 3, for example, after the card connector 2 and card holder 3 are connected by a snap-fit ​​mechanism, the Bluetooth positioning module is powered on, the user's smart terminal establishes a connection with the Bluetooth positioning module, and the anti-theft protection function is enabled through the user's smart terminal settings. When the anti-theft protection function is not disabled, the Hall switch 24 loses the magnetic force of the magnetic block, indicating abnormal separation of the card connector 2 and card holder 3, and an alarm is immediately triggered. The Bluetooth positioning module is connected to a buzzer alarm, and the upper surface of the guide limit block and the upper surface of the card holder are respectively provided with sound holes corresponding to the buzzer alarm. Of course, in the absence of a buzzer alarm, an alarm can also be triggered via the user's smart terminal. For user smart terminals running Apple systems, the Bluetooth positioning module of this invention is compatible with Apple's Find My network protocol.

[0029] In specific implementation, the Hall switch 24 mentioned above may not be necessary. Instead, an independent power switch can be used to manually control the Bluetooth positioning module to turn on or off. In this implementation, a connection status detection switch for detecting the connection status between the card connector and the card socket can be provided on the insertion end face of the guide limit block. The connection status detection switch is a contact micro switch or an infrared sensor switch. The connection status detection switch is connected to the Bluetooth positioning module, and the alarm reminder function of the Bluetooth positioning module can be activated through the connection status detection switch.

[0030] The combination lock mechanism 4 used in this utility model can be a combination lock mechanism composed of various existing multi-group combination dials. That is, it generally includes a combination dial assembly, a sliding rod inserted into the combination dial assembly, a pin on the sliding rod corresponding to the notch slot of the combination dial assembly, and a return spring sleeved on the sliding rod. When the notches of each combination dial of the combination dial assembly correspond to the positions of the pins on the sliding rod, when the sliding rod is pressed, the pins on the outer wall of the sliding rod can pass through the notches of each dial, and the sliding rod can compress the return spring and retract. In order to prevent the sliding rod, which is close to the vertical state of the elastic locking arm 21, from obstructing the insertion of the elastic locking arm 21 into the locking seat 3, a locking tongue 41 is provided at the end of the sliding rod to abut against the inner side of the elastic locking arm 21.

[0031] To better achieve the locking effect of the combination lock mechanism 4 on the elastic locking arm 21, a lock hole is provided on the inner side of the elastic locking arm 21 corresponding to the position of the locking tongue 41; the locking tongue 41 is inserted into the lock hole under the action of the return spring, preventing the elastic locking arm 21 from retracting; to achieve unlocking, an unlock button is provided on the locking seat 3, which is connected to the sliding rod and is used to drive the sliding rod to retract after compressing the spring when the combination lock mechanism is in the correct password state. That is, when the password is correct, pressing the unlock button will cause the sliding rod to retract under the oblique pushing force of the unlock button, causing the locking tongue 41 to retract from the lock hole.

[0032] Reference Figure 4 As shown, when reinforcing and binding a suitcase, this utility model generally passes through the suitcase handle to prevent it from slipping out of the suitcase. In order to adapt to suitcases of different sizes, one end of the strap body 1 is sewn and fixedly connected to the connecting hole of the snap fastener 3; the other end passes around the connecting hole on the snap fastener 2 and is sewn and fixedly connected to the D-ring buckle. The D-ring buckle is fitted onto the strap body 1, and the binding length of this utility model can be adjusted by adjusting the position of the D-ring buckle on the strap body 1.
