Description

Technical Field

[0001] This invention relates to the field of alarm equipment technology, specifically a wireless charging anti-theft device. Background Technology

[0002] When displaying electronic products such as mobile phones and tablets, consumers often operate and experience them, making them vulnerable to theft during peak hours. Therefore, many booths are equipped with anti-theft devices, even wireless ones. For example, the utility model patent with publication number CN207558136U describes a wireless charging anti-theft device, and the utility model patent with publication number CN217360906U describes an anti-theft device and electronic equipment. Both mention using wireless charging to charge the anti-theft components to maintain the alarm's battery life. In particular, the utility model patent with publication number CN217360906U describes a wireless charging technology that uses a mobile phone to reverse-charge the anti-theft tag, both aimed at improving the alarm system's battery life.

[0003] However, the existing technologies described above have two drawbacks. First, the anti-theft tags, which are directly attached to the back of electronic products such as mobile phones, are easily torn off, causing the anti-theft alarm function to fail. This type of anti-theft alarm technology has inherent limitations in its structural design. Second, the anti-theft tags need to be continuously turned on and cannot be turned off, resulting in relatively high power consumption. Since shop display cases are open for extended periods, the anti-theft tags can easily run out of power and shut down. While mobile phones can reverse charge, once the phone's battery is depleted or it is manually turned off, wireless reverse charging will not work.

[0004] Therefore, in practical applications, wireless charging anti-theft devices also need to have the function of preventing the anti-theft tag from being deliberately removed without an alarm, and they also need to have continuous battery life. Summary of the Invention

[0005] In light of the above description of the current state of the technology, the purpose of this invention is to provide a wireless charging anti-theft device that can effectively solve the technical problems of existing wireless charging anti-theft devices, such as the ease with which anti-theft tags can be removed and insufficient battery life.

[0006] To achieve the above objectives, the present invention employs a wireless charging anti-theft device, comprising an anti-theft tag supporting wireless charging installed on an electronic product, and an anti-theft clamping seat for holding the electronic product. An alarm is triggered when the anti-theft tag moves a predetermined distance from a set position. A substrate is fixed to the back of the electronic product, and the anti-theft tag is fixedly mounted on the side of the substrate facing away from the electronic product. A switch of a first alarm circuit is connected between the anti-theft tag and the electronic product, and the first alarm circuit is energized and triggers an alarm when the anti-theft tag is torn from the substrate. The anti-theft clamping seat includes... The back ring has an annular back ring and clamping blocks integrally connected to both sides of the back ring. The area between the two clamping blocks is for inserting electronic products to fix them on the anti-theft clamping seat. The side of the clamping block that contacts the electronic product is provided with a switch part of the second alarm circuit. When the electronic product is separated from the clamping block, the second alarm circuit is energized and alarms are triggered. A disc is rotatably mounted concentrically on the inner side of the back ring. A strip-shaped charging hole is opened along the diameter direction of the disc. The size of the strip-shaped charging hole must allow the anti-theft tag to be fully exposed, but the substrate cannot be removed from the strip-shaped charging hole and is in contact with the two opposite sidewalls in the width direction of the strip-shaped charging hole.

[0007] Furthermore, the anti-theft tag is a UWB tag, and the booth for placing electronic products is equipped with UWB base stations around the perimeter and top. It also includes an intelligent control module, which has a preset safe distance threshold. It analyzes the location data transmitted from the UWB base stations to determine whether there is an anomaly, and triggers an alarm when there is an anomaly.

[0008] Furthermore, electric field sensing electrodes are laid under the surface of the display stand to create a stable electric field distribution around the electronic product when it is placed on the stand. The electric field sensing electrodes monitor the changes in electric field strength and distribution in real time. When the electronic product moves away from the display stand, the electric field strength and distribution change, and the electric field sensing electrodes transmit the change data to the intelligent control module for data analysis. If the change in electric field exceeds the set fluctuation range and the change in UWB positioning distance exceeds the set value, an alarm is triggered.

[0009] Furthermore, the surface and sides of the display stand are equipped with capacitive sensing plates to form a capacitive sensing area. The intelligent control module monitors the change in capacitance value in real time. When the electronic product reaches a set distance from the display stand, the change in capacitance value exceeds the preset range. At the same time, the change in electric field exceeds the set fluctuation range and the change in UWB positioning distance also exceeds the set value, triggering an alarm.

[0010] The present invention is selectively designed such that: the first alarm circuit is disposed on a circuit board or the substrate, the circuit board being mounted on the back of the electronic product and located in a position covered by the disc.

[0011] The present invention is selectively designed such that the switching part of the first alarm circuit includes a first contact and a second contact. The first contact is connected to the substrate, and the second contact is connected to the back of the anti-theft tag. When the anti-theft tag is attached to the substrate, the two contacts make contact to disconnect the first alarm circuit. When the two contacts separate, the first alarm circuit is powered on.

[0012] Furthermore, the switch of the second alarm circuit is a spring-loaded button. When the electronic product is clamped by the clamping block, the button is in the pressed state, and the second alarm circuit is disconnected. When the button is released, the second alarm circuit is powered on.

[0013] Furthermore, the substrate also includes a pair of positioning blocks located on its two sides. The positioning blocks are composed of two plates that form an L-shape with each other. One plate perpendicular to the substrate is an insert plate, and the other plate close to the disc is a pad plate. The two opposing insert plates can be inserted into the strip-shaped charging hole to achieve contact between the substrate and the two opposing sidewalls in the width direction of the strip-shaped charging hole.

[0014] Furthermore, the end face of the back ring is coaxially provided with an annular groove, the groove wall of which is threaded so that the annular groove is axially screwed into by a threaded pressure ring and comes into contact with the edge of the disc; a lever protrudes from one side of the disc, and a pre-tension spring that is always compressed is provided between the threaded pressure ring and the back ring.

[0015] Furthermore, the substrate is vertically connected to the surfaces at both ends, with the plug-in posts symmetrically arranged at both ends of the anti-theft tag; it also includes a wireless charging base, which comprises an inclined mounting plate and a horizontal support plate, the mounting plate and the support plate being fixedly connected as a whole, and the mounting plate being located entirely inside the back ring, with a support base fixed to the lower part of the support plate; a charging coil is provided in the center of the mounting plate, and a socket is provided on each side of the mounting plate, with sockets in which the two plug-in posts are inserted, so that when the plug-in posts are inserted into the sockets, the wireless charging area of ​​the anti-theft tag is directly facing the charging coil.

[0016] This invention discloses a wireless charging anti-theft device. Building upon the traditional method of using anti-theft tags attached to electronic products for alarm purposes, this invention further mounts the anti-theft tag onto a substrate. The tag is connected to the substrate; once the tag is removed, an alarm is triggered. Since the substrate cannot be removed, the tag cannot be forcibly removed. Furthermore, the substrate is restrained by a disc-shaped anti-theft clamp, preventing arbitrary removal. To remove the substrate, the clamp must first be removed; however, an anti-detachment alarm exists between the clamp and the electronic product, preventing unauthorized removal without an alarm.

[0017] Furthermore, this invention also features a dedicated wireless charging dock for directly charging the anti-theft tag, eliminating the need for a built-in power source or reverse charging from a mobile phone, thus extending the charging time. More specifically, the connector in this invention matches the wireless charging dock, allowing for quick alignment of the anti-theft tag or its wireless charging area with the charging area of ​​the wireless charging dock for rapid charging. No manual adjustment of the charging position is required; once the electronic device is returned to its original position, the anti-theft tag will automatically begin wireless charging, enhancing the battery life of the anti-theft alarm.

[0018] Therefore, it can be seen that the present invention is based on multiple anti-theft alarm mechanisms, which are interlocked, so that the wireless charging anti-theft device can effectively prevent theft of electronic devices such as mobile phones and tablets. Moreover, it has a wireless charging function, which can quickly wirelessly charge the anti-theft tag, ensuring that the present invention is always in an anti-theft alarm state.

[0035] The embodiments of the present invention will be fully described below. Some core features of the embodiments will be specifically illustrated in the accompanying drawings, wherein the same or similar reference numerals in the drawings represent the same or similar technical features, or structures, steps, or processes with similar functions. Other embodiments derived by those skilled in the art based on these embodiments without requiring creative effort are also within the protection scope of the present invention.

[0036] Please see Figure 1The wireless charging anti-theft device shown includes not only an anti-theft tag 7 supporting wireless charging installed on the electronic product, but also an anti-theft clamp for holding the electronic product. That is, once the anti-theft tag 7 moves a predetermined distance from its designated position to a set value, an alarm is triggered, notifying booth personnel to check the electronic product. In practice, anti-theft alarms based on the anti-theft tag 7 are commonly used with electronic products such as mobile phones 1 or tablets. Specifically, in this embodiment, a substrate 6 is also fixed to the back of such electronic products. This substrate 6 is used to install the anti-theft tag 7. That is, in this embodiment, the anti-theft tag 7 is not directly pasted onto the back of the mobile phone 1, but is installed through the substrate 6 at a suitable position on the back of the mobile phone 1. Specifically, an anti-theft tag 7 is fixedly installed on the side of the substrate 6 facing away from the electronic product. In particular, a switch for a first alarm circuit (or a first alarm element) is specifically connected between the anti-theft tag 7 and the electronic product. The opening and closing of this switch directly affects whether the anti-theft tag 7 is connected to the substrate 6. That is, when the anti-theft tag 7 is torn off the substrate 6, the switch performs a corresponding action, thereby energizing the first alarm circuit and triggering an alarm. Therefore, it is impossible to evade anti-theft alarm monitoring by removing the anti-theft tag 7. Furthermore, as... Figure 1This anti-theft clamp includes a ring-shaped back ring 2 and clamping blocks 3 connected to both sides of the back ring 2. Specifically, the clamping blocks 3 can be made of elastic material so that they can be pried outwards to insert the mobile phone 1. Alternatively, the clamping blocks 3 and the back ring 2 can be installed horizontally and elastically to form a clamping force. That is, when the two clamping blocks 3 are pulled apart in opposite directions, the area between the two clamping blocks 3 is used to insert electronic products. After releasing the clamping blocks 3, the two clamping blocks 3 fix the mobile phone 1 on the anti-theft clamp. In order to avoid the power button and other parts of the mobile phone 1, a receiving cavity 21 can be set in one side of the clamping block 3 to accommodate these buttons. In terms of clamping the mobile phone 1 and other electronic products, the above structure is similar to that of a general selfie stick and a car mobile phone holder, which serves to connect and fix electronic products. The difference is that in this embodiment, the side of the clamp 3 that contacts the electronic product is provided with a switch for the second alarm circuit (or a second alarm element). When the electronic product is separated from the clamp 3, the second alarm circuit is powered on and alarms are triggered. The reason for designing an alarm mechanism here is to prevent someone from deliberately removing the anti-theft clamp and then trying to remove the substrate 6 in order to remove the anti-theft tag 7. However, the anti-theft tag 7 can only be easily torn off or removed when the anti-theft clamp is removed. To achieve this design objective, in this embodiment, a disc 5 is installed concentrically on the inner side of the back ring 2. The disc 5 cannot be removed from the back ring 2, and a strip-shaped charging hole 501 is provided on the disc 5 along its diameter. The size of this strip-shaped charging hole 501 must allow the anti-theft tag 7 to be fully exposed. For example, the common anti-theft tag 7 is rectangular, and the strip-shaped charging hole 501 must be larger than the anti-theft tag 7 in both length and width directions to better expose the anti-theft tag 7 or its wireless charging area (for intuitive description, the alignment of the anti-theft tag 7 and the wireless charging base mentioned later refers to the alignment of the wireless charging area of ​​the anti-theft tag 7 with the wireless charging area of ​​the wireless charging base). Specifically, the wireless charging area of ​​the anti-theft tag 7 can be set on its surface, or an independent wireless charging module can be used as a component attached to one end of the anti-theft tag 7 for efficient wireless charging.

[0037] In this embodiment, another crucial structural feature is the shape and size of the substrate 6 mentioned above. This design prevents the substrate 6 from being removed from the strip-shaped charging hole 501 and requires it to contact the two opposite sidewalls in the width direction of the strip-shaped charging hole 501. Consequently, the substrate 6 cannot be directly removed from the strip-shaped charging hole 501. Instead, the anti-theft clamp must be removed, and then the substrate 6 and the anti-theft tag 7 can be removed from the back of the phone 1. The contact between the substrate 6 and the inner sidewall of the strip-shaped charging hole 501 serves two purposes: firstly, it facilitates quick positioning and installation by quickly placing the disc 5 onto the substrate 6 through the strip-shaped charging hole 501, thus enabling rapid installation of the anti-theft clamp; and secondly, it prevents the anti-theft clamp from sliding up and down along the phone 1 when the anti-theft tag 7 is not vertically attached. Together with the clamping block 3, it more firmly defines the fixed positioning relationship between the anti-theft clamp and the phone 1, preventing manual movement of the anti-theft clamp. Another crucial function of the above design is that the disc 5, which rotates within the back ring 2, is designed to better accommodate different mobile phones 1 or different anti-theft tags 7, ensuring that the anti-theft tags 7 can be fully inserted into the opening of the strip charging port 501 for wireless charging. For example... Figure 1 The anti-theft tag 7 is horizontally affixed to the center of the back of the phone 1. However, in practice, it's impossible to accurately affix the anti-theft tag 7 to this position. This is due to both human error and limitations of the phone 1 itself. Generally, a product label 22 is affixed to the back of the phone 1, containing network license information, product qualification information, etc., and indicating that it should not be removed arbitrarily. Therefore, the anti-theft tag 7 cannot be directly affixed to the product label 22. Furthermore, the product label 22 of the phone 1 is generally affixed arbitrarily to the back of the phone 1. The size and placement of the product label 22 vary between different phones and manufacturers, and most of the time it's randomly affixed to a certain area, for example, it might be placed on... Figure 6 If it's placed diagonally in the center of the back, then the anti-theft tag 7 would have to be moved to another location, such as... Figure 7 The other locations shown are used for mounting, therefore the structure of the strip charging hole 501 on the disc 5 is particularly necessary. At this time, the posture of the mobile phone with the anti-theft tag 7 attached at an angle when connected to the wireless charging dock is as follows: Figure 8 As shown.

[0038] In the above embodiments, regarding the design of the wireless charging function of the anti-theft tag 7, in addition to the prior art mentioned in the background art, those skilled in the art can also refer to other technical documents to make adaptive designs. Specifically, it can be integrated into the tag itself, or the wireless charging module can be installed on an independent component, which is then connected to the anti-theft tag 7 as part of the anti-theft tag.

[0039] As a specific embodiment, for the anti-theft tag 7, any anti-theft technology of the commercially available anti-theft tag 7 can be adopted. This embodiment recommends the use of UWB tags because they have extremely high positioning accuracy within a small range. UWB base stations can be set up around and on top of the exhibition stand where electronic products are placed. In addition, a corresponding intelligent control module is also equipped. The intelligent control module presets a safe distance threshold, analyzes the location data transmitted by the UWB base station to determine whether there is an anomaly, and triggers an alarm when there is an anomaly. The specific application of UWB tag anti-theft technology is already very mature in the existing technology, and will not be described in detail here.

[0040] In addition to the above-mentioned anti-theft alarm methods, in this embodiment, electric field sensing electrodes are laid under the surface of the display stand to create a stable electric field distribution around the electronic products when they are placed on the stand. The electric field sensing electrodes monitor the changes in electric field strength and distribution in real time. When the electronic products move away from the stand, the electric field strength and distribution change, and the electric field sensing electrodes transmit the change data to the intelligent control module for data analysis. If the data shows that the electric field change exceeds the set fluctuation range, and the change in the distance of the mobile phone 1 based on UWB positioning exceeds the set value, an alarm is triggered. This can avoid false alarms when external electronic devices interfere with the electric field around the stand, and it is more accurate than alarms based solely on UWB positioning function.

[0041] Furthermore, in this embodiment, capacitive sensing plates are provided on both the surface and sides of the display stand to form a capacitive sensing area. The intelligent control module monitors changes in capacitance values ​​in real time. As the electronic product moves away from the display stand, the electric field strength and distribution change. The electrodes transmit the change data to the intelligent control module. The intelligent control module analyzes the data. If the electric field change exceeds the normal fluctuation range and matches the change in UWB positioning distance, an anomaly is confirmed, improving alarm accuracy. That is, when the electronic product reaches a set distance from the display stand, the capacitance value change exceeds the preset range. At the same time, the electric field change exceeds the set fluctuation range, and the UWB positioning distance change also exceeds the set value, triggering an alarm.

[0042] In the above design, as an optional design scheme, the first alarm circuit can be set on a circuit board 23 or a substrate 6. When set on circuit board 23, this circuit board 23 must be installed on the back of the electronic product and in a position covered by the disc 5. The circuit board 23 must also be protected and insulated. In essence, the first alarm circuit here can be implemented using the principle that when a normally closed switch is closed, the circuit is normally open. Once this switch is opened, that is, when the anti-theft tag 7 is separated from the substrate 6, the circuit is closed.

[0043] Regarding the control of the aforementioned first alarm circuit, the present invention recommends the following design: the switching part of the first alarm circuit includes a first contact and a second contact. These two contacts can actually be the ends of two wires. The first contact is connected to the substrate 6, and the second contact is connected to the back of the anti-theft tag 7. When the anti-theft tag 7 is affixed to the substrate 6, the two contacts make contact, causing the first alarm circuit to disconnect. This can be achieved by connecting the first alarm circuit in parallel with a branch circuit. The contact of the ends of the wires where the two contacts are located is equivalent to reconnecting a broken wire, thus closing the branch circuit. The branch circuit then short-circuits the first alarm circuit, or alarm element. Once the two contacts separate, the branch circuit disconnects, energizing the first alarm circuit and triggering the alarm. In actual manufacturing, those skilled in the art can adapt the specific circuit design; this embodiment does not impose limitations.

[0044] As one specific implementation structure, the switch of this second alarm circuit is a spring-loaded button. When the electronic product is clamped by the clamping block 3, the button is in the pressed state, and the second alarm circuit is disconnected. When the button is released, the second alarm circuit is powered on. It should be noted that, to prevent someone from attempting to remove half of this anti-theft clamp from the mobile phone 1 and forcibly remove the partially exposed substrate 6, such as... Figure 4 As shown, it is best to install these buttons in pairs at the upper and lower ends of the clamping block 3. The second alarm circuit is only disconnected when all four buttons are pressed simultaneously. Releasing any one button will reconnect the second alarm circuit and trigger the alarm. This way, releasing any button at any end will trigger the alarm, ensuring that the anti-theft tag 7 alarms before it is exposed. As another implementation method, the triggering mechanism for the second alarm circuit can also be designed as follows: Figure 5 As shown, a sliding element 12 is in contact with a pressure sensing element 14 through an elastic element 13. All three elements are installed inside the clamping block 3. When not in use, the sliding element 12 protrudes from the clamping block 3 to contact the mobile phone 1. Thus, as long as the mobile phone 1 is placed in the two clamping blocks 3, it will inevitably squeeze the sliding element 12, causing the pressure sensing element 14 to have a pressure value within a specific range. Once the mobile phone 1 is removed from the clamping block 3, the pressure sensing element 14 will quickly decrease or even become zero, thereby triggering an alarm.

[0045] like Figures 1-2 In this embodiment, the substrate 6 also includes a pair of positioning blocks 8 located on both sides thereof, which are also referred to in the following sections. Figure 9 The positioning block 8 is composed of two plates forming an L-shape, meaning that the side of the positioning block 8 essentially has a step. Of the two plates in the positioning block 8, the plate perpendicular to the substrate 6 is an insert plate 802, and the plate in close contact with the disc 5 is a pad plate 801. The two opposing insert plates 802 can be inserted into the strip-shaped charging hole 501 to achieve the contact between the substrate 6 and the two opposing sidewalls of the strip-shaped charging hole 501 in the width direction, as mentioned above. For ease of installation and positioning, it can be arranged as follows...Figure 9 The end of the insert plate 802 is beveled as shown.

[0046] To ensure that the disc 5 can be fixed when rotated so that the strip charging hole 501 is directly opposite the anti-theft tag 7, such as... Figures 1-2 and Figure 3 As shown, an annular groove is coaxially provided on the end face of the back ring 2. The groove wall is threaded so that a threaded pressure ring 4 is axially screwed into the annular groove and comes into contact with the edge of the disc 5, thus pressing and fixing the disc 5. To facilitate the rotation of the disc 5, a lever 9 can be provided protruding on one side of the disc 5. The lever 9 is turned to rotate the threaded pressure ring 4. A pre-tension spring 10 that is always compressed is also provided between the threaded pressure ring 4 and the back ring 2, making the connection of the threaded pressure ring 4 more secure.

[0047] Finally, to facilitate fast and efficient charging of the anti-theft tag 7, such as... Figures 1-2 As shown, on the surfaces of the substrate 6 near both ends, insertion posts 11 are perpendicularly connected to it. The insertion posts 11 are symmetrically arranged at both ends of the anti-theft tag 7, and their length is preferably such that they do not expose the end face of the back ring 2. Meanwhile, this embodiment also includes a wireless charging dock, such as... Figures 10-11 This wireless charging stand includes an inclined mounting plate 15 and a horizontally positioned support plate 16. The mounting plate 15 and the support plate 16 are fixedly connected as a single unit and can be integrally molded. The size of the mounting plate 15 allows it to be positioned entirely inside the back ring 2, meaning the anti-theft clamp can cover the mounting plate 15. A support base 20 is fixed to the lower part of the support plate 16 to support electronic products such as mobile phones 1. More specifically, a charging coil 18 is located in the center of the mounting plate 15, and a socket 17 is located on each side of the mounting plate 15. Each socket 17 has a socket hole 19 for inserting two plugs 11, ensuring that when the plugs 11 are inserted into the socket holes 19, the wireless charging area of ​​the anti-theft tag 7 is directly aligned with the charging coil 18. When placing electronic products on the wireless charging stand, the anti-theft tag 7 or its wireless charging area is directly aligned with the charging coil 18, eliminating the need for manual alignment adjustments. The installation structure of the anti-theft tag 7 during charging is as follows: Figure 12 As shown

[0048] For larger or heavier electronic devices such as tablets, it is also possible to... Figure 13 As shown, the plug-in post 11 is mounted on the disk 5, and correspondingly, the mounting plate 15 of the wireless charging base is structured according to... Figure 14 The design can be adjusted by simply changing the position of the socket 17. Because the back of a large tablet computer has a large surface area, the anti-theft tag 7 can be more flexibly placed. Therefore, setting the plug 11 on the disc 5 will not significantly affect the alignment of the wireless charging area of ​​the anti-theft tag 7 with the charging coil 18.

[0049] The above series of specific implementation details are merely some preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the claims of the present invention. Those skilled in the art, based on their understanding of the above embodiments and referring to the basic principles recorded in the claims of the present invention, can easily modify the design ideas, but these modifications still fall within the scope of protection of the invention.
