Description

Technical Field

[0001] This utility model relates to the field of electronic anti-theft devices, specifically a universal rechargeable electronic anti-theft device. Background Technology

[0002] Rechargeable electronic anti-theft devices are electronic devices that integrate charging and anti-theft functions, and are widely used in commercial displays, public places, and other scenarios. Their main purpose is to prevent theft of electronic products (such as mobile phones and tablets) while providing charging services. In product display areas of shopping malls, merchants often place electronic products for sale on display stands for customers to experience. At this time, the rechargeable electronic anti-theft device can charge these electronic products and, through its own anti-theft mechanisms, such as alarm functions, sound an alarm when the electronic products are illegally moved, thus protecting the merchant's property.

[0003] Many existing electronic anti-theft devices have relatively simple clamping structures, lacking effective limiting and fixing devices. For example, some anti-theft devices only use simple slots to fix electronic products. The size of these slots is often fixed and cannot be flexibly adjusted according to the shape and size of different electronic products. When the placed electronic product does not match the size of the slot, a tight fit cannot be achieved, causing the electronic product to easily wobble within the slot when subjected to external forces, resulting in displacement. When clamping electronic products, due to the lack of elastic cushioning, the clamping force is often rigid and difficult to adapt to the shape of the electronic product. When encountering electronic products with uneven or curved surfaces, rigid clamping cannot guarantee sufficient contact with the surface of the electronic product, resulting in uneven distribution of clamping force. In some areas, the clamping force is insufficient, making it easy for the electronic product to detach from the clamping part when subjected to vibration or impact. The materials used in the clamping parts of some electronic anti-theft devices have low friction. For example, some plastic materials have smooth surfaces and cannot provide sufficient friction to prevent the electronic product from sliding when in contact with it. When electronic products are placed on an anti-theft device, even with some clamping force, they can easily shift or even slip off due to insufficient friction when subjected to slight external force or vibration. Therefore, existing electronic anti-theft devices suffer from poor clamping stability, making it easy for electronic products to shift or detach after being clamped, and require further improvement.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is combined Figures 1-7 This utility model provides a detailed description of a universal rechargeable electronic anti-theft device:

[0022] A universal rechargeable electronic anti-theft device includes a housing 1. A driving assembly is disposed inside the housing 1. The driving assembly includes a control panel 6, a main control circuit board, and a power supply. The control panel 6 and the power supply are electrically connected to the main control circuit board. A recess 3 is formed by an inward indentation on the side of the housing 1. Two limiting plates 10 extend outward from the end of the housing 1 near the recess 3, symmetrically arranged between the two limiting plates 10, forming a limiting groove 11 between them. An elastic dot 12 is provided on the side of each limiting plate 10. A spring 13 is disposed inside each elastic dot 12. One end of the spring 13 is connected to the limiting plate 10, and the other end of the spring 13 is connected to the inner wall of the elastic dot 12. The diameter of the spring 13 gradually increases from the limiting plate 10 towards the elastic dot 12. One end of the housing 1 is inwardly concave. The housing 1 has an upward-facing cavity 2, which contains a cylinder 7. The height of the cylinder 7 is less than the height of the outer shell 1. The cylinder 7 has several circular grooves 8 inside, with the diameter of the grooves gradually increasing from the center of the cylinder 7 outwards. One end of the outer shell 1 has a charging cable 9, which is arranged around the inside of the circular grooves 8. One end of the outer shell 1 also has an alarm light 4, which is electrically connected to the main control circuit board. The bottom of the outer shell 1 has several feet 14, which are symmetrically arranged between adjacent feet 14. The bottom of the outer shell 1 also has several support blocks 15, which are equidistantly arranged between adjacent support blocks 15. The feet 14 and the support blocks 15 are all on the same horizontal plane. One end of the outer shell 1 also has several heat dissipation holes 5, which are equidistantly arranged between adjacent heat dissipation holes 5. The groove 3 on the side of the outer casing 1 and the limiting groove 11 formed by two symmetrical limiting plates 10 can be used to fix electronic products such as mobile phones in a specific position. The limiting groove 11 formed between the two limiting plates 10 can adapt to electronic products of different thicknesses, enhancing versatility. The elastic dot 12 provided on the side of the limiting plate 10 contains a spring 13, and the diameter of the spring 13 gradually increases from the limiting plate 10 towards the elastic dot 12. This design allows the elastic force provided by the spring 13 to adaptively adjust according to the pressure when the elastic dot 12 is compressed, tightly pressing against the surface of the electronic product and preventing the electronic product from easily slipping or being moved, thus providing a good fixing effect. The cylinder 7 provided in the cavity 2 at one end of the outer casing 1 has a circular groove 8 whose diameter gradually increases from the center outwards, and the charging cable 9 can be wrapped around the inside of the circular groove 8. This design not only facilitates the orderly storage of the charging cable 9 and prevents it from becoming tangled and messy, but also allows for flexible placement of the appropriate circular slot 8 based on the length and diameter of the charging cable 9, improving the convenience and adaptability of the charging cable 9 storage and making the overall anti-theft device neater and more orderly.

[0023] In this embodiment, the cavity 2 and cylinder 7 at one end of the outer casing 1 provide an orderly storage space for the charging cable 9. The charging cable 9 is wrapped around the tapered diameter groove 8, avoiding the problems of tangling and knotting, which not only extends the service life of the charging cable 9 but also improves the overall aesthetics and portability of the device. The alarm light 4 at one end of the outer casing 1 is electrically connected to the main control circuit board, which can quickly emit a warning light when the anti-theft device detects an abnormality, effectively attracting the attention of surrounding people, enhancing the anti-theft effect, and improving the visibility and warning capability of the device in complex environments. The base 14 and support block 15 at the bottom of the outer casing 1 ensure the stability of the device when placed. The heat dissipation holes 5 at one end of the outer casing 1 effectively promote the dissipation of heat inside the device. The equidistantly arranged heat dissipation holes 5 optimize the airflow path, improve heat dissipation efficiency, ensure that the main control circuit board and other electronic components operate stably at a suitable temperature, and reduce the risk of failure caused by overheating.

[0024] This embodiment of a universal rechargeable electronic anti-theft device provides a limiting plate 10, a limiting groove 11, and an elastic dot 12 on the side of the outer shell 1. Through the elastic action of the spring 13, the elastic dot 12 can be tightly attached to the electronic product, thereby achieving a stable locking of the electronic product and preventing the electronic product from shifting due to external force collision or vibration, greatly improving stability.

[0025] In practical use, electronic products (such as mobile phones) are directly inserted into the receiving cavity 2, so that the electronic products are connected to the charging cable 9, and can be displayed while charging. When it is necessary to pick up the electronic products, simply pull them out. When fixing the electronic products, one end of the electronic products is inserted into the limiting groove 11. Through the elastic action of the spring 13, the elastic dot 12 can be tightly attached to the electronic products, thereby achieving a stable locking of the electronic products. The operation is simple and highly practical.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
