Spherical Loss Prevention Device

Abstract

In the field of electronic equipment technology, we provide a spherical loss prevention device that improves appearance and texture and has superior waterproofing performance. [Solution] The spherical anti-loss device includes an inner shell assembly comprising an upper shell 110 and a lower shell 120 joined together, a fixed frame 200, an electronic control assembly 300 fixed within the fixed frame and comprising a battery 310 and circuit boards 321, 322 electrically connected to each other, a buzzer 400 electrically connected to the circuit boards, and a first outer shell made of rubber material with an opening, which is tightly fitted to the outside of the inner shell assembly, and a second outer shell attached to the outside of the inner shell assembly and filling the opening, wherein the seams between the first outer shell and the second outer shell and the seams between the upper shell and the lower shell do not overlap. Because this spherical anti-loss device has two layers of protective shells, it can provide better protection and improve the overall structural strength. The first outer shell is made of rubber material and therefore has elasticity that can absorb some of the impact force from the outside. Since the seams between the first outer shell and the second outer shell, and the seams between the upper shell and the lower shell, do not overlap, it becomes difficult for water from the outside to penetrate into the interior of the inner shell assembly through the seams.

Description

Technical Field

[0001] The present invention relates to the technical field of electronic devices, and particularly to a spherical loss prevention device.

Background Art

[0002] In family life, there are many items in the house, and they may be stored in various places. Therefore, when a specific item is needed temporarily, it is necessary to search for it, which wastes time and energy and may not be easily found. To address the above problems, loss prevention devices have emerged on the market. This device can be connected to an item via a hook, rope, or other connectors. When it is necessary to search for the item, the loss prevention device emits sound, light, or other position information, enabling the user to quickly locate the position of the loss prevention device and find the item. This reduces the workload of searching for items.

[0003] In order to perform its position identification function, the loss prevention device first needs to have a function of transmitting signals including audio signals, optical signals, wireless signals, etc. to inform the user of its position. Also, a self-power supply function is required to reduce dependence on external energy so that it can be freely connected to various items without losing its signal transmission ability due to energy depletion. Furthermore, the structure needs to be miniaturized to avoid being large in volume and affecting the user experience.

[0004] Therefore, considering the manufacturing cost of the product, most of the commercially available loss prevention devices have a buzzer and a power supply built-in, and the outer shell is an integrated rigid plastic part with sufficient structural strength to protect the internal electronic devices. However, the outer shell made of hard plastic has an ordinary feel and cannot enhance the style of the product. Furthermore, the current loss prevention devices have insufficient waterproof performance, so when accidentally dropped into water, water easily penetrates, affecting normal functions and not being suitable for use in more complex situations.

Summary of the Invention

[0005] This invention aims to solve at least one of the above-mentioned technical problems that exist in the prior art. Therefore, this invention proposes a spherical loss prevention device that improves appearance and texture and provides better waterproofing performance. [Means for solving the problem]

[0025] In household life, there are many items in the house, and they may be stored in various places, so when you need a specific item temporarily, you have to search for it, wasting time and energy, and it can be difficult to find. To address the above problem, anti-loss devices have appeared on the market. These devices can be attached to items via hooks, ropes, or other connectors. When the item needs to be found, the anti-loss device emits sound, light, or other location information, allowing the user to quickly locate the device and find the item. This reduces the burden of searching for items.

[0026] To perform its location-finding function, an anti-loss device must first have the ability to transmit signals, including voice, light, and wireless signals, to inform the user of its location. It also needs a self-powering function to reduce reliance on external energy, allowing it to connect freely to various items without losing signal transmission capabilities due to energy depletion. Furthermore, its structure must be miniaturized to avoid large size and impact on the user experience.

[0027] Therefore, considering the manufacturing costs of the product, most commercially available anti-loss devices have a built-in buzzer and power supply, and the outer shell is a single, rigid plastic component with sufficient structural strength to protect the internal electronic devices. However, the hard plastic outer shell has a mediocre feel and fails to enhance the style of the product. Furthermore, current anti-loss devices have insufficient waterproofing, so if accidentally dropped in water, water can easily enter, affecting normal function and making them unsuitable for use in more complex situations.

[0028] Therefore, this invention proposes a spherical anti-loss device. In this spherical anti-loss device, the inner shell assembly constitutes a structure that protects the internal electronic control assembly, buzzer, and related structural members, performing the most basic protective function. Furthermore, a two-layer protective shell structure is formed by providing a first outer shell and a second outer shell on the outside of the inner shell assembly. Such a design has the following advantages. Firstly, the two layers of protective shell can provide a better protective function and improve the overall structural strength of this spherical anti-loss device. Secondly, since the first outer shell is an elastic rubber material that can absorb some of the impact force from the outside, the possibility that external impacts will affect the normal operation of the electronic control assembly and buzzer can be reduced. Thirdly, since the seams between the first outer shell and the second outer shell, and the seams between the upper shell and the lower shell do not overlap, water from the outside is less likely to penetrate into the interior of the inner shell assembly through the seams, thereby improving the waterproof performance of this spherical anti-loss device.

[0029] Referring to Figure 1, the spherical anti-loss device in this embodiment of the present invention includes an inner shell assembly, a fixed frame 200, an electronic control assembly 300, a buzzer 400, a first outer shell 500, and a second outer shell 600. The inner shell assembly functions as the first protective shell structure of the spherical anti-loss device, protecting the fixed frame 200, electronic control assembly 300, buzzer 400, and other related electronic devices and structural components mounted therein. Both the first outer shell 500 and the second outer shell 600 constitute the second protective shell structure of the spherical anti-loss device and are fitted onto the outside of the inner shell assembly. The two-layer protective shell structure further enhances the protective effect against internal devices and also improves the waterproof performance of the spherical anti-loss device. Inside the spherical anti-loss device, the fixed frame 200 is used to fix the electronic control assembly 300, which is used to control the activation and deactivation of the buzzer 400. When the buzzer 400 is activated, the location of the spherical anti-loss device is audibly notified to the user, allowing the user to easily find the specific item connected to the spherical anti-loss device. In this invention, the specific item refers to an item whose location the user needs to pinpoint using the spherical anti-loss device.

[0030] Specifically, the inner shell assembly includes an upper shell 110 and a lower shell 120 joined and combined together, both of which are bowl-shaped. When the upper shell 110 and the lower shell 120 are joined together, a cavity is formed between them. This cavity can house a fixed frame 200, an electronic control assembly 300, a buzzer 400, and other related electronic devices and structural components.

[0031] The fixing frame 200 is attached to the lower shell 120. As a structural component inside the spherical anti-loss device, the fixing frame 200 fixes the electronic control assembly 300 inside the spherical anti-loss device, preventing the electronic control assembly 300 from detaching from the inner shell assembly and causing damage by repeatedly colliding with the inner shell assembly when the spherical anti-loss device is subjected to an external force. The fixing frame 200 and the lower shell 120 can be fixed to each other using snap connections, bolt connections, adhesive connections, etc., so further details will not be provided here.

[0032] The electronic control assembly 300 includes a battery 310 and a circuit board 320 that are electrically connected to each other, and is fixed as a whole within a fixed frame 200, thereby fixing the electronic control assembly 300 to the inner shell assembly via the fixed frame 200. In the electronic control assembly 300, the battery 310 supplies power to the circuit board 320, allowing the spherical anti-loss device to operate without relying on external energy, thereby improving its portability. To make the structure more compact, a button battery is used as the battery 310 in this embodiment, but as can be understood, other types and models of batteries can also be used for power supply, but this will not be explained in further detail here. The circuit board 320 integrates circuits and related electronic devices to ensure the proper operation of the spherical anti-loss device. When a user needs to find the spherical anti-loss device and a specific item attached to it, the circuit board 320 sends a signal to a buzzer 400 electrically connected to it, causing the buzzer 400 to emit a sound, indicating the location of the spherical anti-loss device with an audible alarm, making it easier for the user to find the item.

[0033] In some embodiments, a wireless transmission module is integrated into the circuit board 320. This wireless transmission module can communicate with the user's mobile or stationary electronic device via Bluetooth, Wi-Fi, or wireless transmission. The user controls the circuit board 320 via this mobile or stationary electronic device to activate the buzzer 400 and sound an alarm. Here, mobile electronic device refers to a portable human-computer interaction electronic device such as a mobile phone, tablet, PDA, or laptop. Computer terminal refers to a stationary human-computer interaction electronic device such as a home computer or industrial control computer. In some other embodiments, a timing module is integrated into the circuit board 320. This timing module records time and, when a predetermined time is reached, automatically activates the buzzer 400 to periodically prompt the user to locate the spherical anti-loss device and the specific item connected to it.

[0034] In this embodiment, the user relies primarily on the buzzer sound from the buzzer 400. The audible alarm helps the user locate the spherical anti-loss device and the specific item attached to it. For ease of understanding, in some other embodiments, a light-emitting element may also be attached to the spherical anti-loss device. Since the light-emitting element is electrically connected to the electronic control assembly 300, the circuit board 320 can make the light-emitting element emit light, thereby informing the user of the location of the spherical anti-loss device via an optical signal. Alternatively, a vibrating device may be attached to the spherical anti-loss device. This vibrating device is electrically connected to the electronic control assembly 300, and the circuit board 320 can assist in informing the user of the location of the spherical anti-loss device by vibrating the vibrating device.

[0035] Furthermore, a positioning module can be integrated into the circuit board 320. This positioning module determines location information by satellite positioning and transmits the location information to the user's mobile or fixed electronic device via a wireless transmission module, allowing the user to intuitively understand the location of the spherical anti-loss device.

[0036] Referring to Figure 2, the first outer shell 500 is a rubber member with an opening 510 and is tightly fitted to the outside of the inner shell assembly. The second outer shell 600 is attached to the outside of the inner shell assembly and fills the opening 510. Referring to Figure 3, the second outer shell 600 and the first outer shell 500 are joined to each other so that they can completely cover the outer surface of the inner shell assembly. When attaching the first outer shell 500 and the second outer shell 600 to the outside of the inner shell assembly, the inner shell assembly is first inserted into the first outer shell 500 through the opening 510 of the first outer shell 500. Because the first outer shell 500 is an elastic rubber member, external force can slightly open the opening 510, facilitating the insertion of the inner shell assembly. Because the first outer shell 500 is elastic, it adheres tightly to the outer wall of the inner shell assembly, thus minimizing the gap between the first outer shell 500 and the inner shell assembly and improving the sealing performance of this spherical loss prevention device. Next, the second outer shell 600 is attached to the outside of the inner shell assembly, filling the opening 510. The inside of the second outer shell 600 and the outside of the inner shell assembly can be connected and positioned via a slot structure. Alternatively, the second outer shell 600 can be bonded to the inner shell assembly with adhesive. The second outer shell 600 can be made of hard rubber, which has a certain elasticity, providing a similar feel to the elastic surface of the first outer shell 500, and also has a certain rigidity, allowing it to be stably connected to the inner shell assembly and reducing the possibility of loosening. In addition, by filling the opening 510 of the first outer shell 500, the second outer shell 600 also plays a role in positioning the first outer shell 500, preventing relative movement between the first outer shell 500 and the inner shell assembly.

[0037] Furthermore, the joint between the first outer shell 500 and the second outer shell 600 does not overlap with the joint between the upper shell 110 and the lower shell 120. The reason for this design is that in a configuration where the joint between the first outer shell 500 and the second outer shell 600 overlaps with the joint between the upper shell 110 and the lower shell 120, if water from the outside enters through the joint between the first outer shell 500 and the second outer shell 600, it can easily enter through the joint between the upper shell 110 and the lower shell 120 as well. As a result, water can penetrate into the interior of the inner shell assembly, potentially affecting the normal operation of the electronic control assembly 300, the buzzer 400, and other electronic devices. Therefore, if the joint between the first outer shell 500 and the second outer shell 600 and the joint between the upper shell 110 and the lower shell 120 are designed not to overlap, even if water enters through the joint between the first outer shell 500 and the second outer shell 600, it will need to flow through the gap between the first outer shell 500 and the inner shell assembly to the joint between the upper shell 110 and the lower shell 120 in order to penetrate into the interior of the inner shell assembly. This lengthens the path of water intrusion, reduces the possibility of water intrusion, and improves the overall waterproofness of the spherical anti-loss device.

[0038] Furthermore, referring to Figures 4 and 5, the upper shell 110 has sound vents 1111, and when the buzzer 400 emits sound, the alarm sound is transmitted to the outside through the sound vents 1111, preventing the sound of the buzzer 400 from being easily transmitted to the outside because the spherical loss prevention device is completely sealed. To prevent water from entering the inside of the inner shell assembly through the sound vents 1111, in some embodiments, the sound vents 1111 can be provided with a membrane that is both waterproof and breathable to improve waterproofing. Alternatively, in some other embodiments, the waterproofing of the sound vents 1111 can be ensured by sealing the sound vents 1111 with adhesive on the back of the buzzer 400. The number of sound vents 1111 can be increased or decreased depending on the actual situation. Increasing the number of sound vents 1111 makes it easier for the sound of the buzzer 400 to be transmitted to the outside, but this will not be explained in further detail here.

[0039] Specifically, the upper shell 110 includes an upper shell body 111 and a fastener 112, the fastener 112 being connected to the upper shell body 111 by ultrasonic connection. To allow the spherical anti-loss device to be easily connected to a specific article, a connection groove 1112 is provided in the upper shell body 111, and a connector 1122 is provided in the fastener 112 that crosses the connection groove 1112, the connector 1122 being used to fasten to an external snap. If connection is required, in some embodiments the hook-like structure of the external snap can extend into the connection groove 1112 and fasten to the connector 1122. In some other embodiments the spherical anti-loss device can be connected to a specific article via a rope, specifically the rope can be tied to the connector 1122 by having the end of the rope enter the connection groove 1112, pass through the connector 1122, and then exit the connection groove 1112. In this embodiment, the inner wall of the connecting groove 1112 is an arc-shaped curved surface in order to make it easier to pull the rope out of the connecting groove 1112. This allows the rope to be pushed out of the connecting groove 1112 more easily along the inner wall of the connecting groove 1112 after it has been subjected to an external force and entered the connecting groove 1112.

[0040] Furthermore, the sound vents 1111 are located within the connecting grooves 1112. On the one hand, having the sound vents 1111 within the inwardly recessed connecting grooves 1112 allows the sound vents 1111 to be shielded by the connecting grooves 1112, preventing them from being directly exposed to the outer surface of the upper shell body 111 and thus preventing damage to the appearance of the upper shell body 111. On the other hand, the connecting grooves 1112 are inwardly recessed and used for connecting to specific items, and are therefore not normally exposed to the outside. This reduces the possibility of intrusion or penetration due to water splashing, and minimizes water entering through the sound vents 1111.

[0041] Specifically, in this embodiment, there are two sound-emitting holes 1111, and they are located on the inner wall of the arc-shaped curved surface of the connecting groove 1112.

[0042] Furthermore, since the upper shell 110 and the lower shell 120 are fixed to each other by snaps, the structure is simple and less prone to loosening or detachment. For easy understanding, the upper shell 110 and the lower shell 120 can be fixed to each other by connection methods such as bolt connections and slot connections, but these will not be explained in further detail here. To improve the sealing performance of the joint between the upper shell 110 and the lower shell 120, a sealant layer is further provided at the joint between the upper shell 110 and the lower shell 120. Because the sealant layer is elastic, it can fill the gap between the upper shell 110 and the lower shell 120 after they are joined, preventing water from entering from the outside.

[0043] Furthermore, referring to Figure 6, the circuit board 320 includes a PCBA board 321 and an FPC board 322, where the PCBA board 321 is a rigid circuit board integrating various electronic devices, and the FPC board 322 is a flexible and bendable circuit board that can be appropriately deformed to conform to the internal structure of the inner shell assembly. The circuit board 320 also includes a PVC board 323 that covers the battery 310 together with the FPC board 322. The FPC board 322 is electrically connected to the PCBA board 321, specifically via a metal piece 3222 extending outward from the FPC board 322. The FPC board 322 controls the buzzer 400 by contacting the buzzer 400 via a contact 3221. Furthermore, in order to stably connect the buzzer 400 and the FPC board 322, the buzzer 400 is further provided with buzzer back adhesive 410, and its opposing sides are adhered to the buzzer 400 and the FPC board 322, respectively, serving to support the buzzer 400 and preventing the buzzer 400 from directly applying pressure to the contact 3221. The PCBA board 321 is fixedly mounted to the fixed frame 200. Specifically, in order to make the internal structure of the spherical loss prevention device more compact, the battery 310 is placed between the PCBA board 321 and the FPC board 322, and the metal piece 3222 of the FPC board 322 is made to contact the PCBA board 321 by bypassing the battery 310. To avoid a short circuit caused by the metal piece 3222 contacting the battery 310, as shown in Figure 7, a relief groove 221 is provided on the side of the fixed frame 200 for the metal piece 3222 to pass through, and the fixed frame 200 is positioned between the battery 310 and the metal piece 3222 to avoid contact between the two.

[0044] Furthermore, with respect to the fixed frame 200, referring to Figure 7, the fixed frame 200 includes a base 210, a skirt 220, and a fixing clip 230, with the relief groove 221 located on the outer surface of the skirt 220. The skirt 220 and the fixing clip 230 are provided on the edge of the base 210 and jointly define a space for arranging the battery 310. When the battery 310 is installed in this space, the skirt 220 and the fixing clip 230 restrict the radial displacement of the battery 310, thereby providing a restricting effect on the battery 310. The ends of the fixing clip 230 are provided with fastening portions 231 that extend toward the center of the fixed frame 200, and these fastening portions 231 abut against the ends of the battery 310, restricting the axial displacement of the battery 310. Furthermore, the combined action of the skirt 220 and the fixing clip 230 stably restricts the battery 310 within the fixed frame 200, preventing unintended movement of the battery 310.

[0045] At the fastening portion 231, a wedge-shaped structure is provided at its end, on the side closer to the center of the fixed frame 200. The wedge-shaped structure has an inclined surface, and a step is provided on the rear side of the inclined surface. When the battery 310 is placed in the fixed frame 200 along its axial direction, the inclined surface of the wedge-shaped structure first contacts the side of the battery 310, and the guiding action of the inclined surface ensures that the battery 310 is correctly mounted in the center of the base 210. As the mounting of the battery 310 progresses, the fixed clip 230 is pushed outward by the battery 310, and its kinetic energy is converted into elastic potential energy within the fixed clip 230. When the battery 310 is mounted in the predetermined position, the step passes over the end of the battery 310, the lateral force exerted on the fixed clip 230 by the battery 310 disappears, the elastic potential energy of the fixed clip 230 is converted into kinetic energy, and the fixed clip 230 is reset. The fastening portion 231 is perfectly positioned at the end of the battery 310, and the step abuts against the end of the battery 310, preventing axial movement of the battery 310, and ultimately completing the installation of the battery 310.

[0046] To make it easy to understand, if it is necessary to remove the battery 310, applying an outward lateral force to the fixing clip 230 moves the fastening portion 231 away from the battery 310, thereby unlocking the battery 310 and allowing the battery 310 to be removed from the fixing frame 200 along its axial direction.

[0047] Furthermore, in order to securely mount the battery 310 within the fixed frame 200, an adhesive layer 330 is provided between the battery 310 and the base 210 for bonding them together.

[0048] Furthermore, in order to increase the deformation range of the fixing clip 230 and facilitate the insertion of the battery 310, the fixing clip 230 does not come into contact with the skirt 220. The first end of the fixing clip 230 is connected to the base 210, and the second end of the fixing clip 230 is provided with a fastening portion 231 for securing the battery 310. When the fixing clip 230 is subjected to a lateral force, the fixing clip 230 flexes with the first end as the fulcrum, thereby obtaining a larger deformation range.

[0049] Furthermore, the base 210 transitions from a first surface 211 to a second surface 212 along its thickness direction, with the battery 310 mounted on the first surface 211 of the base 210 and the PCBA board 321 mounted on the second surface 212 of the base 210. This isolates the battery 310 and the PCBA board 321 from each other at the base 210, preventing direct contact and short circuits. Specifically, the second surface 212 of the base 210 is further provided with a fixing block 2121, and the PCBA board 321 is provided with an engagement groove 3211 that can engage with the fixing block 2121. When the PCBA board 321 is mounted on the second surface 212, the fixing block 2121 is inserted into the engagement groove 3211 to fix the PCBA board 321. For ease of understanding, the PCBA board 321 and the base 210 can also be fixed to each other by snap connections, bolt connections, adhesive connections, etc., but these will not be explained in further detail here.

[0050] Optionally, to facilitate control of the electronic control assembly 300, a button 700 may be further provided in the spherical anti-loss device, as shown in Figure 8. This button 700 is mounted on the lower shell 120 and contacts a switch on the PCBA board 321 via a force transmission member 121 within the lower shell 120. The first outer shell 500 shields the button 700 when it covers the inner shell assembly, improving the visual consistency of the spherical anti-loss device and preventing the button 700 from being exposed and detracting from its appearance. However, since the first outer shell 500 is made of elastic silicon, even if it deforms under external force, it does not affect the normal operation of the button 700. When the button 700 is pressed, the applied force is transmitted via the force transmission member 121 to a preset switch on the PCBA board 321, thereby physically activating the PCBA board 321. This allows the spherical anti-loss device to be controlled without the need for additional equipment.

[0051] Furthermore, in this embodiment, the inner shell assembly has a spherical structure, and the first outer shell 500 and the second outer shell 600 are joined to each other to form a spherical structure. Therefore, because this spherical anti-loss device is spherical, it is easier for the user to hold and the feel is also improved. In addition, the spherical appearance is uniform and makes it easy to distinguish from other types of spherical anti-loss devices when they are on the market.

[0052] Furthermore, the surfaces of the first outer shell 500 and the second outer shell 600 are composed of several polygonal structures joined together. These polygonal structures are distributed across the entire surface of the first outer shell 500 and the second outer shell 600, which prevents the surface of the spherical anti-loss device from being too smooth and gives it a layered texture. In addition, since the joint between the first outer shell 500 and the second outer shell 600 overlaps with the joints between the polygonal structures, the joint between the first outer shell 500 and the second outer shell 600 can be concealed, preventing an unnatural appearance.

[0053] The embodiments of the present invention have been described in detail above with reference to the drawings, but the present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the knowledge of those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments and features of the present invention can be combined with each other, as long as they do not contradict each other. [Explanation of Symbols]
