[0036] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0037] Please refer to the following: Figures 1 to 3The battery pack charging structure provided by this utility model will now be described. The battery pack charging structure includes a charging base 1, at least two sets of limiting structures, and an indicator light 4. The charging base 1 has a charging cavity 11; a plug-in interface 12 is provided on the bottom wall of the charging cavity 11; at least two sets of limiting structures are respectively provided in the charging cavity 11; the at least two sets of limiting structures are used to limit and fix battery packs 5 of different sizes, so that battery packs 5 of different sizes can be inserted into the charging cavity 11 and connected to the plug-in interface 12; the indicator light 4 is provided on the charging base 1.
[0038] The charging dock 1 can be equipped with a battery management module to monitor the charging status, voltage, current, and temperature of the battery pack 5, and adjust charging parameters based on the monitoring data to ensure charging safety. The battery management module can also connect to external devices via a communication interface, enabling the transmission of the battery pack 5's charging and health status data to the external devices for further analysis and management. Furthermore, the charging dock 1 can be equipped with overcharge protection, over-discharge protection, short-circuit protection, and temperature protection functions to ensure the safety of the charging process and the lifespan of the battery pack 5.
[0039] At least two sets of limiting structures are located within the charging cavity 11. Each set of limiting structures corresponds to a battery pack 5 of a certain external size and can limit and fix the corresponding battery pack 5 within the charging cavity 11. Specifically, each set of limiting structures can be an annular structure formed by multiple limiting posts, with the battery pack 5 confined within the corresponding annular structure. Each set of limiting structures can also be limiting blocks distributed on the side wall of the charging cavity 11 or limiting surfaces formed on the side wall of the charging cavity 11 itself. This embodiment does not limit the specific form of the limiting structures, as long as the charging cavity 11 can assemble and limit battery packs 5 of different external sizes.
[0040] This embodiment, by setting at least two sets of limiting structures within the charging cavity 11, can effectively adapt to battery packs 5 of different shapes and sizes. This design allows the charging base 1 to simultaneously meet the charging needs of battery packs 5 of different shapes and sizes, avoiding the inconvenience of users needing to purchase multiple charging bases 1 due to different battery pack sizes, and significantly improving the versatility and practicality of the charging base 1.
[0041] The limiting structure can not only adapt to battery packs 5 of different sizes, but also firmly fix the battery pack 5 after it is inserted into the charging cavity 11, preventing the battery pack 5 from shaking or falling off during charging, and ensuring that the charging interface of the battery pack 5 and the plug-in interface 12 of the charging base 1 always maintain good contact, thereby improving the stability and reliability of charging.
[0042] Specifically, during the charging operation, the battery pack 5 only needs to be inserted into the charging cavity 11 to automatically connect to the power interface 12, without the need for the user to manually align or adjust it. The operation is simple and convenient, greatly improving the user experience.
[0043] Indicator light 4 can display the charging status of battery pack 5 in real time (such as charging, fully charged, fault, etc.). Users can intuitively understand the charging progress without the need for other devices, making it convenient for users to monitor the charging process and detect abnormalities in a timely manner (such as poor contact or charging failure), thereby improving the safety and controllability of the charging process.
[0044] Preferably, the battery pack charging structure is used in conjunction with the lamp fixture, meaning it is an integral part of the lamp fixture and embedded within it. When it is needed to charge the battery pack, both the charging structure and the battery pack 5 can be removed from the lamp fixture to charge the battery pack 5 and replace the lamp fixture with a fully charged battery pack 5, without affecting the normal operation of the lamp fixture. Alternatively, when the lamp fixture is not in use, the battery pack charging structure and the battery pack 5 do not need to be removed from the lamp fixture; they can be directly plugged into AC power to charge the battery pack.
[0045] Compared with the prior art, the battery pack charging structure provided by this utility model achieves efficient adaptation, stable fixation, and visual monitoring of charging status for battery packs 5 of different sizes by setting at least two sets of limiting structures in the charging cavity 11 and setting indicator lights 4 on the charging base 1. This not only improves the charging efficiency of the charging base 1 and enhances the ease of use of the lamp, but also optimizes the user experience and enhances the safety and reliability of the charging process.
[0046] In some embodiments, the above-mentioned at least two sets of limiting structures can be adopted as follows: Figure 1 The structure shown is described in the following document. Figure 1 At least two sets of limiting structures are respectively formed on the side wall of the charging cavity 11.
[0047] The limiting structure is directly formed on the side wall of the charging cavity 11. On the one hand, this makes the overall structure of the charging base more compact, saves space, and optimizes the size of the charging base, making it easy to carry and store. On the other hand, it eliminates the need for additional fixing devices or adjustment mechanisms, further simplifying the overall structure of the charging structure and making it easier to design, process, and manufacture.
[0048] Please see Figure 1 Based on the above embodiments, the charging cavity 11 has a rectangular cavity structure; the two long side walls of the charging cavity 11 are respectively provided with concave arc surfaces; at least two sets of limiting structures are divided into a first limiting structure 2 and a second limiting structure 3; the first limiting structure 2 includes the two long side walls and two short side walls of the charging cavity 11; the second limiting structure 3 includes two concave arc surfaces.
[0049] The rectangular design of the charging cavity 11 can accommodate most common rectangular battery packs 5, meeting the charging needs of mainstream devices. The concave arc surfaces on the two long side walls can accommodate battery packs 5 with curved edges or cylindrical shapes, further expanding the compatibility of the charging base.
[0050] Specifically, the two long sidewalls and two short sidewalls of the charging cavity 11 form a first limiting structure 2, which can firmly fix the rectangular battery pack 5, prevent it from shaking or shifting during charging, and ensure its precise docking with the plug-in interface 12.
[0051] Two concave arc surfaces are arranged opposite each other to form a second limiting structure 3, which can be adapted to a battery pack 5 with an arc edge or a cylindrical shape, fit the edge of the arc battery pack 5, provide uniform support, and prevent the battery pack 5 from sliding or tilting during charging.
[0052] The first limiting structure 2 is designed as the inner peripheral wall of the charging cavity 11, and the second limiting structure 3 is designed as a concave arc surface. The limiting is directly formed by the inner wall surface of the charging cavity 11, eliminating the need to install other fixing devices or adjustment mechanisms inside the charging cavity 11 or on the side wall of the charging cavity 11, which further simplifies the overall structure of the charging structure.
[0053] Please see Figure 1 Based on the above implementation, the center line of the concave arc surface coincides with the center line of the long side wall, and the plug-in interface 12 is located at the center point of the bottom wall of the charging cavity 11.
[0054] The charging port 12 is located at the center point of the bottom wall of the charging cavity 11. In other words, the charging structure is simultaneously located at the center point of the first limiting structure 2 and the center point of the second limiting structure 3. This positional limitation enables automatic calibration. Whether the battery pack 5 is rectangular or curved, it will automatically align with the charging port 12 after being inserted into the charging cavity 11, eliminating the need for manual adjustment by the user. This simplifies the charging process, improves the user experience, reduces energy loss due to poor contact, and increases charging efficiency.
[0055] In some embodiments, the charging dock described above may also employ, for example... Figure 1 , Figure 2 and Figure 3 The structure shown is described in the following document. Figure 1 , Figure 2 and Figure 3 The charging base 1 has at least two charging chambers 11 as described above. Each charging chamber 11 has the same structure, including the first limiting structure 2, the second limiting structure 3, the plug-in interface 12, and the indicator light 4.
[0056] The charging dock has at least two charging chambers 11, which means that the charging structure can charge multiple battery packs 5 at the same time, improving charging efficiency and further enhancing the compatibility and practicality of the charging dock. It is especially suitable for scenarios that require frequent replacement of battery packs 5 or simultaneous use of multiple devices.
[0057] In addition, by combining the first limiting structure 2, the second limiting structure 3, the power plug interface 12 and the indicator light 4, each charging chamber 11 can work independently, and also ensures that the charging status of each battery pack 5 is monitored and managed in real time.
[0058] In some embodiments, the charging dock described above may be as follows: Figure 3 The structure shown is described in the following document. Figure 3 The charging base 1 includes an outer shell 13 and an inner shell 14. The outer shell 13 is a thin-walled cover with a cavity. The inner shell 14 is disposed inside the outer shell 13, and similarly, the inner shell 14 is also a thin-walled cover with a cavity (the cavity is the charging cavity 11).
[0059] The outer shell 13 serves as the external protective layer of the charging base, effectively protecting the internal components from external impacts, dust, or liquid intrusion. The inner shell 14 serves as the supporting structure for the charging cavity 11, providing a stable fixation and precise connection for the battery pack 5. The cavity between the outer shell 13 and the inner shell 14 forms an air circulation channel, effectively dispersing heat and preventing overheating.
[0060] Both the outer shell 13 and the inner shell 14 are thin-walled structures with a double-layer design, which enhances the durability and safety of the charging base 1 and improves heat conduction efficiency. It also reduces the weight of the charging base 1, making it easier to carry. The cavity of the outer shell 13 can also accommodate other electrical components that enable charging.
[0061] Preferably, please refer to Figure 1 Based on the above embodiments, the top surface of the inner shell 14 and the top surface of the outer shell 13 are integrally formed. The integrated design of the inner shell 14 and the outer shell 13 makes the overall structure of the charging base more compact and saves space.
[0062] In addition, the top surface of the inner shell 14 is integrally formed with the top surface of the outer shell 13, which makes the top surface streamlined and conforms to the ergonomic appearance design, improving the aesthetics and grip comfort of the charging base.
[0063] In some embodiments, the outer casing 13 may also be as follows: Figure 2 and Figure 3 The structure shown is described in the following document. Figure 2 and Figure 3 The bottom end of the outer shell 13 protrudes outward in a ring shape, forming a support platform 131. This ring-shaped support platform 131 increases the contact area between the charging base and the contact surface (such as a desktop or floor), making the charging base more stable when placed and less prone to tipping or sliding. Furthermore, the ring-shaped support platform 131 can adopt a streamlined or ergonomic design, enhancing the aesthetics and grip comfort of the charging base.
[0064] In some embodiments, the outer casing 13 may also be as follows: Figure 3 The structure shown is described in the following document. Figure 3 The bottom surface of the outer casing 13 has an opening, and a rubber pad 15 is provided at the opening.
[0065] During charging, the battery pack 5 and the charging base may generate heat. The opening on the bottom of the outer casing 13 can form an air circulation channel to effectively dissipate heat, avoid overheating, and ensure the safety and stability of the charging process.
[0066] A rubber pad 15 covers the opening on the bottom surface of the outer casing 13, increasing friction and preventing the charging base from shifting due to vibration or external force during use. Furthermore, the rubber pad 15 acts as a buffer, reducing the impact of external shocks on the internal components of the charging base. When the charging base is accidentally dropped or bumped, the rubber pad 15 absorbs some of the impact force, protecting the internal components from damage.
[0067] In addition, the rubber pad 15 can be made of breathable material or designed with vents to further optimize heat dissipation.
[0068] In some embodiments, the indicator light 4 is an LED light that can display different colors or flashing patterns according to the charging status to indicate the charging progress of the battery pack 5.
[0069] LED lights, through different colors or flashing patterns, can intuitively convey the charging status of battery pack 5 to users. For example, a solid red light indicates that battery pack 5 is charging; a solid green light indicates that battery pack 5 is fully charged; and a flashing yellow light indicates a charging abnormality (such as poor contact, battery malfunction, etc.), helping users to keep track of the charging status in a timely manner and enhancing the controllability and safety of the charging process.
[0070] Based on the same inventive concept, this application also provides a portable lamp, including a lamp body, a battery pack 5, and the aforementioned battery pack charging structure.
[0071] The battery pack 5 is detachably installed inside the lamp body. The battery pack 5 can be used as a charging tool on its own or in many lamps.
[0072] The battery pack charging structure is embedded inside the lamp body and is detachably connected to it. When it is needed to charge the battery pack, it and the battery pack 5 can be removed from the lamp to charge the battery pack 5 and replace the lamp with a fully charged battery pack 5 without affecting the normal use of the lamp. Alternatively, when the lamp is not in use, the battery pack charging structure and the battery pack 5 do not need to be removed from the lamp; they can be directly plugged into an AC power source to charge the battery pack.
[0073] The portable lamp provided by this utility model adopts the aforementioned battery pack charging structure and battery pack 5. A replaceable battery pack 5 is installed inside the lamp body. If the battery pack 5 is depleted, a new battery pack 5 can be replaced, thus ensuring the convenience and flexibility of the portable lamp. The battery pack charging structure can be detached from the lamp body and can charge multiple replacement battery packs 5 simultaneously, improving charging efficiency. Furthermore, the detachable connection between the battery pack and the lamp body allows for a more compact structure, making the lamp easier to carry and store.
[0074] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
