Description

Technical Field

[0001] This utility model relates to the field of light bulb technology, and in particular to a dual-purpose rechargeable magnetic light bulb. Background Technology

[0002] With the continuous development of lighting technology, the types of lamps used in daily life are becoming increasingly diverse. Traditional light bulbs are usually installed directly on fixed lamp holders using standard threaded lamp bases (such as E27 or E14) and are powered by 220V AC mains electricity. These traditional light bulbs have a single function and rely entirely on the power grid. They cannot function in the event of a power outage, or in special scenarios such as outdoors, storage rooms, or carriages where there is no AC mains power interface, and they lack portability.

[0003] To address the needs for power outages or portable lighting, emergency bulbs with detachable shades and built-in batteries have gradually appeared on the market. However, existing detachable bulbs still have many shortcomings in practical applications:

[0004] First, existing detachable connection structures between lamp holders and lamp covers are often not robust enough. They typically rely on simple plug-and-play friction or conventional clips for fixation, which can easily loosen after repeated disassembly and reassembly by the user. This not only poses a safety hazard of the lamp cover accidentally falling and breaking, but also leads to poor contact at the conductive contacts between the lamp holder and the lamp cover, affecting normal power supply.

[0005] Secondly, the disassembled lampshade is very inconvenient to use alone. Existing split bulbs, after being removed, can usually only be held by the user or placed flat on a horizontal table. They cannot be easily fixed in a specific position (such as being attached to the hood when repairing a car, or fixed to the door frame when there is a power outage), making it difficult to truly free the user's hands.

[0006] Finally, many existing products' lampshade modules lack independent charging ports, and must be reinstalled and connected to AC power after the battery is depleted, which severely limits their applicability as portable lamps and their flexibility in supplementing battery life.

[0007] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a dual-purpose rechargeable magnetic light bulb that is stable in connection, easy to disassemble and assemble, and convenient to use.

[0012] To further address the technical problems addressed by this utility model, the dual-purpose rechargeable magnetic bulb provided by this utility model includes a slot for one of the first and second latching parts, and a flexible latch for the other. The slot includes an arc-shaped groove on the outer wall of the first or second mounting plane, with a through hole at one end. The latch is L-shaped and includes a vertical extension extending along the bulb's axial direction and a circumferential extension extending in the circumferential direction.

[0013] The positioning structure includes a positioning groove provided on the inner side of the corresponding first mounting plane or second mounting plane and located on one side of the through hole, and a positioning protrusion protruding on the inner side of the circumferential extension.

[0014] During the process of the latch being inserted into the arc-shaped groove and undergoing relative rotation, the circumferential extension passes through the through hole, and the positioning protrusion on the inner side of the circumferential extension is locked in the corresponding positioning groove.

[0015] To further address the technical problems addressed by this utility model, the dual-purpose rechargeable magnetic bulb provided by this utility model includes a first contact disposed on the first mounting plane and electrically connected to the first charging module, and a second contact disposed on the second mounting plane and electrically connected to the battery module; at least one of the first contact and the second contact is an elastic contact, and when the lamp head module is docked with the lamp cover module, the first contact and the second contact abut against each other to achieve electrical conduction.

[0016] To further address the technical problems to be solved by this utility model, the dual-purpose rechargeable magnetic bulb provided by this utility model has a switch assembly on the side wall of the lampshade body. The switch assembly is electrically connected to the battery module and the light-emitting module and is used to control the opening and closing of the light-emitting module.

[0017] To further address the technical problems addressed by this utility model, the dual-purpose rechargeable magnetic bulb provided by this utility model has a charging port on its lampshade body. The charging port is electrically connected to the second charging module and is used to charge the battery module via an external power source.

[0019] In order to further solve the technical problems to be solved by this utility model, the dual-purpose rechargeable magnetic bulb provided by this utility model includes an LED light panel and a plurality of LED beads disposed on the LED light panel, and at least a portion of the lampshade body is made of a light-transmitting material.

[0020] In order to further solve the technical problem to be solved by this utility model, in the dual-purpose rechargeable magnetic bulb provided by this utility model, when the lampshade module is separated from the lamp head module, the lampshade module can be independently adsorbed onto an external ferromagnetic object by the magnetic component, and the light-emitting module is powered by the battery module.

[0021] In order to further solve the technical problems to be solved by this utility model, the dual-purpose rechargeable magnetic bulb provided by this utility model has anti-slip textures on the outer walls of the lamp head module and the lamp cover module.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] First, the electromechanical co-operation quick-release architecture greatly improves the stability of the connection and the ease of operation. This invention, through the cooperation of an L-shaped elastic latch and an arc-shaped through-hole slot, supplemented by an elastic contact design, achieves both high-strength physical mechanical locking and stable electrical connection with a single rotation, solving the problems of loosening and poor contact in existing split-type bulbs. Users only need a simple relative rotation to simultaneously achieve high-strength physical locking and stable electrical conduction, effectively solving the technical pain points of traditional split-type bulb connections being prone to loosening and frequent disassembly leading to poor contact.

[0024] Secondly, the truly independent power supply and charging system breaks the limitations of conventional portable light bulbs in terms of battery life. The lampshade module not only has a built-in battery module and independent control switch, but also creatively adds an external charging interface, transforming it into a completely independent portable light fixture after being detached from the lamp holder. When the power is depleted, users do not need to put it back into the original lamp holder to charge it through a conventional external power source, greatly improving the mobility of emergency lighting and mobile use.

[0025] Third, the concealed magnetic expansion design significantly broadens the product's application scenarios in complex working conditions. By recessing a receiving groove on the mounting surface at the bottom of the lampshade and embedding a non-protruding magnetic component, it ensures a smooth and close fit between the two module ends when combined, and also gives the lampshade a strong spatial adsorption capability when separated. This allows it to be directly and firmly attached to ferromagnetic objects such as machine tools, car hoods, or refrigerators, truly freeing up your hands. Attached Figure Description

[0027] Figure 1 This is an assembly diagram of the present invention;

[0028] Figure 2 This is an exploded view of the present invention;

[0030] Figure 4 This is a schematic diagram of the snap-fit ​​structure. Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 4As shown, this embodiment provides a dual-purpose rechargeable magnetic light bulb. The bulb adopts a split design, mainly comprising two parts: a lamp head module 10 and a lamp cover module 20. Through a specific mechanical and electrical connection structure, the lamp head module 10 and the lamp cover module 20 can be stably combined for use as a regular lighting bulb, and can also be easily disassembled, allowing the lamp cover module 20 to be used independently as an emergency light source or a portable night light.

[0033] Specifically, the lamp holder module 10 includes a lamp holder body 11. A threaded connector 12 is provided at the bottom end of the lamp holder body 11 (i.e., the end that connects to the lamp holder in the assembled state) for screwing into a standard AC lamp holder to obtain AC power; while a first mounting surface 13 is provided flat at the other end of the lamp holder body 11. To enable power supply and charging of subsequent modules, a first charging module 14 (including a circuit board and a transformer module) is integrated into the internal cavity of the lamp holder body 11. This first charging module 14 is electrically connected to the threaded connector 12 and can convert AC power into suitable DC power (e.g., around 15V).

[0034] The lampshade module 20 includes a lampshade body 21. To ensure light emission, at least a portion of the lampshade body 21 is made of a high-transmittance light-transmitting material such as PC or acrylic. The lampshade body 21 integrates a light-emitting module 22, a battery module 23, and a second charging module 24. The light-emitting module 22 specifically includes an LED light board and a plurality of LED beads uniformly mounted on the LED light board to provide a high-brightness lighting source. The bottom of the lampshade body 21 has a second mounting surface 25, which is spatially aligned and fits perfectly with the first mounting surface 13.

[0035] To achieve a connection between the two modules that is both "energized" and "stable", an energizing structure and a snap-fit ​​structure are designed between the first mounting plane 13 and the second mounting plane 25.

[0036] The snap-fit ​​structure is used to detachably and securely connect the first mounting plane 13 and the second mounting plane 25 together. Specifically, the snap-fit ​​structure includes several first snap-fit ​​portions evenly arranged around the center of the first mounting plane 13, and several second snap-fit ​​portions evenly arranged around the center of the second mounting plane 25. The user only needs to align and fit the first mounting plane 13 and the second mounting plane 25, and rotate the lamp holder body 11 and the lamp cover body 21 relative to each other to achieve snap-fit ​​fixing or unlocking. To enhance the stability of the snap-fit, a positioning structure is also provided between the first and second snap-fit ​​portions. After the first and second snap-fit ​​portions are snapped together, they are further positioned and locked by the positioning structure.

[0037] To provide sufficient friction during rotation, the outer walls of both the lamp head module 10 and the lamp cover module 20 are thoughtfully provided with anti-slip textures, which greatly improves the user's feel and ease of operation when disassembling and assembling.

[0038] In the specific construction of the snap-fit ​​structure, in this embodiment (taking the snap-fit ​​tongue as the lamp holder and the snap-fit ​​groove as the lamp cover as an example), the first snap-fit ​​part is specifically a flexible snap-fit ​​tongue 15, and the second snap-fit ​​part is specifically a snap-fit ​​groove 27. The snap-fit ​​groove 27 includes an arc-shaped groove 271 recessed on the outer wall of the second mounting plane 25. The arc-shaped groove 271 serves as a guide channel, with a through hole 272 extending through one end, and a positioning groove 273 adjacent to the through hole 272 is provided on the inner side of the second mounting plane 25. The snap-fit ​​tongue 15, which cooperates with it, has an overall L-shaped structure, including a vertical extension 151 extending vertically along the bulb axis and a circumferential extension 152 extending horizontally in the circumferential direction, and a positioning protrusion 153 protruding on the inner side of the circumferential extension 152. The positioning protrusion 153 and the positioning groove 273 cooperate to form the above-mentioned positioning structure.

[0039] During assembly, the circumferential extension 152 of the latch 15 is inserted into the arc-shaped groove 271. Then, the lamp cover body 21 is twisted to rotate relative to it. The circumferential extension 152 passes through the through hole 272 along the trajectory. At this time, relying on the material elasticity of the latch 15, the positioning protrusion 153 on the inner side of the circumferential extension 152 will "click" and lock into the corresponding positioning groove 273, thereby completing the physical locking to prevent detachment and making the connection extremely stable.

[0040] While achieving mechanical locking, the energizing structure simultaneously completes circuit connection. The energizing structure includes a first contact 16 located on the first mounting plane 13 and electrically connected to the first charging module 14, and a second contact 28 located on the second mounting plane 25 and electrically connected to the battery module 23. To absorb assembly tolerances and ensure excellent contact, at least one of the first contact 16 and the second contact 28 is designed as a spring-loaded elastic contact (such as a PogoPin). When the lamp head module 10 mates with the lamp cover module 20 and is rotated and locked in place, the end faces of the first contact 16 and the second contact 28 abut tightly, achieving electrical conduction. At this time, the first charging module 14 can charge the battery module 23.

[0041] When the lampshade module 20 needs to be used as a portable light source independently (e.g., during a power outage or while camping in the wild), the user can simply rotate it in the opposite direction to remove the lampshade module 20. In this case, the built-in battery module 23 provides independent power to the light-emitting module 22. For convenient operation when using it alone, a switch assembly 29 is provided on the side wall of the lampshade body 21. This switch assembly 29 is electrically connected to the battery module 23 and the light-emitting module 22, and the user can control the opening and closing of the light-emitting module 22 at any time by pressing or tossing the switch assembly 29.

[0042] Furthermore, to address the battery life issue of the lampshade module 20 when disconnected from mains power, the lampshade body 21 is also equipped with an independent charging port 241 (e.g., a Type-C interface), which is electrically connected to the internal second charging module 24. When the battery module 23 is depleted, the user does not need to reinstall it into the lamp head module 10; they can directly charge it by connecting it to the charging port 241 via an external power source such as a power bank or mobile phone charger, significantly enhancing its portability.

[0043] It is worth mentioning that, in order to expand the usage scenarios in the separated state, the second mounting surface 25 is recessed with a receiving groove 251, and a magnetic suction element 26 (such as a high-strength neodymium iron boron magnet) is embedded in the receiving groove 251. In order not to interfere with the tight connection between the two mounting surfaces, the outer surface of the magnetic suction element 26 does not protrude from the end face of the second mounting surface 25. When the lamp cover module 20 is separated from the lamp head module 10, the user can use the bottom magnetic suction element 26 to independently attach the lamp cover module 20 to external ferromagnetic objects such as machine tools, car hoods, and refrigerator doors, completely freeing the user's hands and meeting the needs of various complex working conditions such as maintenance and emergency lighting.

[0044] In summary, the dual-purpose rechargeable magnetic light bulb of this invention breaks through the limitations of traditional light bulbs that are "fixedly installed and powered by a single source".

[0045] This utility model, through the cooperation of an L-shaped elastic latch and an arc-shaped through-hole slot, supplemented by an elastic contact design, achieves high-strength physical and mechanical locking and stable electrical connection in a single rotation action, solving the problems of loosening and poor contact in existing split bulbs.

[0046] The lampshade module of this utility model not only has a built-in battery module and switch assembly, but also creatively adds an independent charging port, so that after it is separated from the lamp head module, it can be completely transformed into a fully functional independent portable lamp, freeing it from dependence on the original lamp holder for charging.

[0047] This invention, by embedding a magnetic suction component on the bottom surface that does not protrude from the mounting plane, ensures a flat connection when the parts are joined, and also provides strong spatial suspension and adsorption capabilities when the parts are separated, greatly expanding the application boundaries of the product.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
