Description

Technical Field

[0001] This disclosure relates to the technical field of portable power banks, and in particular to a portable outdoor power bank structure. Background Technology

[0002] Light travel, a travel style centered on light packing, convenience, and relaxation, emphasizes short, frequent trips to unwind within limited budgets and time. Characterized by low cost, high flexibility, and a strong therapeutic effect, it is gradually becoming a new choice for urban dwellers to relieve stress and explore life. During light travel, mobile phones and lighting devices are typically powered by portable power banks. However, limited by the capacity of a single power bank (usually 30,000-50,000 mAh), multiple power banks are often needed to ensure continuous device use, especially for multiple charges and nighttime lighting during a 1-2 day trip. However, multiple power banks not only increase luggage weight (each power bank weighs approximately 800g-1100g) but also take up extra backpack space, making the backpack cramped and inconvenient to organize and access items. This forces travelers to spend more time and energy managing these power banks, significantly reducing the convenience and comfort of light travel and impacting the overall travel experience.

[0003] To address the aforementioned issues, some manufacturers have conducted further research and development. For example, existing technology patent CN222673933U2 proposes a portable power bank with a detachable power supply. By detachably mounting the power supply onto the main body, users only need to carry one main body and the required number of detachable power supplies to power their mobile phones, lighting equipment, and other electrical devices. This greatly improves the portability of the portable power bank, thereby significantly enhancing the convenience and comfort of light travel.

[0004] However, during use, the aforementioned portable power bank is prone to separation of the detachable power supply from the main power supply body due to external factors such as collisions or vibrations. This results in low electrical connection stability between the main power supply body and the detachable power supply, which in turn greatly reduces the stability of the portable power bank's use.

[0019] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages: 1. The aforementioned portable outdoor power bank structure, with its battery storage expansion component including a battery storage expansion box and a protective cover, features a battery mounting slot formed in the battery storage expansion box. The protective cover is placed over the opening of the battery mounting slot to form a battery mounting cavity. The protective cover and the battery storage expansion box are detachably connected. The battery mounting cavity is used to accommodate and limit the battery components, allowing users to install or remove the battery components after removing the protective cover. This enables users to carry only one battery storage expansion component and the required number of battery components during light travel to ensure the charging of mobile phones, lighting equipment, and other electrical products.

[0020] 2. Since the battery assembly is contained within the battery mounting cavity, the battery assembly's power connector is electrically connected to the power connector of the battery housing expansion box. This allows the battery housing expansion box and the protective cover to cooperate in securing the battery assembly to a predetermined position within the battery mounting cavity, significantly improving the stability of the electrical connection between the battery assembly's power connector and the battery housing expansion box's power connector. Simultaneously, the battery housing expansion box also protects the battery assembly. Compared to the portable power banks described above, the portable outdoor power bank structure of this application not only effectively prevents damage or short circuits caused by direct collisions with external hard objects, but also effectively prevents the battery cells from detaching from the battery mounting cavity due to external factors such as collisions or vibrations during use. This ensures that the battery assembly's power connector is reliably connected to the power connector of the battery housing expansion box, thereby greatly improving the stability and lifespan of the portable outdoor power bank structure.

[0023] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: like Figures 1 to 11 As shown, a portable outdoor power bank structure 10 according to one embodiment includes a battery storage expansion component 100 and a battery assembly 200. The battery storage expansion component 100 includes a battery storage expansion box 110 and a protective cover 120. The battery storage expansion box 110 forms a battery mounting groove 111. The protective cover 120 covers the opening of the battery mounting groove 111 to form a battery mounting cavity 130. The protective cover 120 is detachably connected to the battery storage expansion box 110. The battery mounting cavity 130 is used to accommodate and install the battery assembly 200, so that the user can install or remove the battery assembly 200 after removing the protective cover 120. During a short trip, the user only needs to carry one battery storage expansion component 100 and carry the required number of battery assemblies 200 as needed to ensure the power supply of mobile phones, lighting equipment and other electrical products. This greatly improves the portability of the portable outdoor power bank structure 10, thereby greatly improving the convenience and comfort of short trips.

[0027] like Figures 1 to 11As shown, further, since the battery assembly 200 is contained within the battery mounting cavity 130, the power receiving end of the battery assembly 200 is used to electrically connect with the power receiving end of the battery receiving expansion box 110, so that the battery receiving expansion box 110 and the protective cover 120 can cooperate with each other to securely contain the battery assembly 200 at a preset position in the battery mounting cavity 130. This greatly improves the electrical connection stability between the power receiving end of the battery assembly 200 and the power receiving end of the battery receiving expansion box 110. At the same time, the battery receiving expansion assembly 100 can also protect the battery assembly 200. Compared with the mobile electric... The portable outdoor power bank structure 10 of this application not only effectively avoids damage or even short circuits to the battery assembly 200 caused by direct collision with external hard objects, but also effectively prevents the battery cell assembly from detaching from the battery mounting cavity 130 due to external factors such as collision or vibration during use. This ensures that the power connection of the battery assembly 200 can be reliably connected to the power connection of the battery housing expansion box 110, thereby greatly improving the stability and service life of the portable outdoor power bank structure 10.

[0028] The aforementioned portable outdoor power bank structure 10, with its battery housing expansion component 100 including a battery housing expansion box 110 and a protective cover 120, features a battery mounting slot 111 formed in the battery housing expansion box 110. The protective cover 120 covers the opening of the battery mounting slot 111, together forming a battery mounting cavity 130. The protective cover 120 is detachably connected to the battery housing expansion box 110. The battery mounting cavity 130 is used to accommodate and limit the battery assembly 200, allowing the user to install or remove the battery assembly 200 after removing the protective cover 120. This enables users to carry only one battery housing expansion component 100 and the required number of battery assemblies 200 during light travel, ensuring the charging of mobile phones, lighting equipment, and other electrical products. This significantly improves the portability of the portable outdoor power bank structure 10, thereby greatly enhancing the convenience and comfort of light travel.

[0029] Furthermore, since the battery assembly 200 is contained within the battery mounting cavity 130, the power connector of the battery assembly 200 is used to electrically connect with the power connector of the battery housing expansion box 110. This allows the battery housing expansion box 110 and the protective cover 120 to cooperate in securing the battery assembly 200 to a predetermined position within the battery mounting cavity 130. This significantly improves the stability of the electrical connection between the power connector of the battery assembly 200 and the power connector of the battery housing expansion box 110. Simultaneously, the battery housing expansion assembly 100 also provides protection for the battery assembly 200. Compared to the portable power banks described in the aforementioned related technologies, this… The proposed portable outdoor power bank structure 10 not only effectively prevents the battery assembly 200 from being damaged or even short-circuited due to direct collision with external hard objects, but also effectively prevents the battery cell assembly from detaching from the battery mounting cavity 130 due to external factors such as collision or vibration during use. This ensures that the power connection of the battery assembly 200 can be reliably connected to the power connection of the battery housing expansion box 110, thereby greatly improving the stability and service life of the portable outdoor power bank structure 10.

[0030] like Figures 1 to 7As shown, in one embodiment, the battery housing expansion box 110 includes an expansion box body 112 and a latching assembly 113. A battery mounting slot 111 is formed in the expansion box body 112. A first positioning hole 1121 is formed on one side of the expansion box body 112 near the opening of the battery mounting slot 111. The expansion box body 112 also forms a guide limiting cavity 1122 communicating with the first positioning hole 1121. The sliding end of the latching assembly 113 is disposed in the guide limiting cavity 1122 and is slidably connected to the inner wall of the guide limiting cavity 1122. The limiting end of the latching assembly 113 is disposed in the first positioning hole 1121. Inside the first positioning hole 1121, a snap-fit ​​positioning flange 121 is formed on one side of the protective cover 120 adjacent to the expansion box body 112. The snap-fit ​​positioning flange 121 is located inside the first positioning hole 1121. The limiting end of the snap-fit ​​locking assembly 113 is used to abut against and limit the snap-fit ​​positioning flange 121 within the first positioning hole 1121, so that the protective cover 120 is fixed to the expansion box body 112. When it is necessary to remove the protective cover 120 from the expansion box body 112, it is only necessary to slide the sliding end of the snap-fit ​​locking assembly 113 along the first guiding direction of the guide limiting cavity 1122 to drive the snap-fit ​​locking assembly 1121. The limiting end of 3 moves away from the snap-fit ​​positioning flange 121 until the limiting end of the snap-fit ​​assembly 113 enters the guide limiting cavity 1122 from the first positioning hole 1121, allowing the user to easily remove the protective cover 120 from the expansion box body 112. When it is necessary to install and fix the protective cover 120 on the expansion box body 112, simply place the protective cover 120 in the preset position of the expansion box body 112 so that the snap-fit ​​positioning flange 121 can extend into the first positioning hole 1121, and then slide the snap-fit ​​assembly 113 along the guide limiting cavity 1122. The sliding direction of the second guide of 122 allows the sliding end of the latching assembly 113 to move the limiting end of the latching assembly 113 toward the snap-fit ​​positioning flange 121 until the limiting end of the latching assembly 113 enters the first positioning hole 1121 from the guide limiting cavity 1122 and abuts against the snap-fit ​​positioning flange 121. This allows the protective cover 120 to be securely fixed to the expansion box body 112, thereby greatly reducing the difficulty of installing and removing the protective cover 120, making it faster and more convenient to replace the battery assembly 200 when the portable outdoor power supply structure 10 is replaced.

[0031] like Figures 3 to 10As shown, in one embodiment, the latching assembly 113 further includes a latching limiting part 1131 and a sliding part 1132. The limiting end of the latching assembly 113 is disposed in the latching limiting part 1131, and the sliding end of the latching assembly 113 is disposed in the sliding part 1132. The latching limiting part 1131 and the sliding part 1132 are fixedly connected. The sliding part 1132 is disposed in the guide limiting cavity 1122 and slides against the inner wall of the guide limiting cavity 1122. The locking and limiting part 1131 is located inside the first positioning hole 1121. The locking and limiting part 1131 is used to limit the locking and positioning flange 121 within the first positioning hole 1121. When it is necessary to remove the protective cover 120 from the expansion box body 112, it is only necessary to slide the sliding part 1132 along the first guiding direction of the guiding and limiting cavity 1122 to drive the locking and limiting part 1131 away from the locking and positioning flange 121. Move until the latching limit end enters the guide limiting cavity 1122 from the first positioning hole 1121, allowing the user to easily remove the protective cover 120 from the expansion box body 112. When it is necessary to install and fix the protective cover 120 on the expansion box body 112, simply place the protective cover 120 in the preset position of the expansion box body 112 so that the latching positioning flange 121 can extend into the first positioning hole 1121. Then slide the sliding part 1132 along the second guiding direction of the guide limiting cavity 1122, so that the sliding part 1132 can drive the latching limit part 1131 to move towards the latching positioning flange 121 until the latching limit part 1131 enters the first positioning hole 1121 from the guide limiting cavity 1122 and abuts against the latching positioning flange 121, thereby allowing the protective cover 120 to be securely fixed on the expansion box body 112.

[0032] like Figure 10 As shown, in this embodiment, the buckle limiting part 1131 and the sliding part 1132 are integrally formed to improve the structural compactness of the buckle locking assembly 113.

[0033] like Figures 3 to 9As shown, in one embodiment, the latching assembly 113 further includes an elastic member 1133. Both ends of the elastic member 1133 are elastically connected to the inner walls of the sliding portion 1132 and the guide limiting cavity 1122, respectively. The elastic member 1133 is used to elastically support the sliding portion 1132 at a preset position in the guide limiting cavity 1122, so that the latch limiting portion 1131 is located within the first positioning hole 1121, allowing the latch to engage when the user pushes the sliding portion 1132 along the first guiding direction of the guide limiting cavity 1122. The sliding part 1132 can slide along the first guiding direction of the guide limiting cavity 1122 through the elastic deformation capability of the elastic member 1133; when the user stops pushing the sliding part 1132, the elastic member 1133 can push the sliding part 1132 along the first guiding direction of the guide limiting cavity 1122 through its own elastic rebound energy until the sliding part 1132 slides to the preset position of the guide limiting cavity 1122, thereby greatly improving the ease of use of the portable outdoor mobile power supply structure 10.

[0034] like Figure 9 As shown, in this embodiment, the elastic element 1133 is a spring or elastic silicone to enable the elastic element 1133 to have good elastic deformation performance and elastic rebound performance.

[0035] like Figures 3 to 5 As shown, in one embodiment, a first abutting plane 1211 is formed on one side of the snap-fit ​​positioning flange 121 adjacent to the protective cover plate 120, and a second abutting plane 11311 is formed on one side of the snap-fit ​​limiting part 1131 opposite to the protective cover plate 120. The snap-fit ​​limiting part 1131 is used to limit the snap-fit ​​positioning flange 121 in the first positioning hole 1121 when the first abutting plane 1211 and the second abutting plane 11311 abut against each other, so that the protective cover plate 120 can be reliably limited to the preset position of the expansion box body 112, effectively preventing the battery cell assembly from falling out of the battery mounting cavity 130 due to external factors such as collision or vibration during the use of the portable outdoor power bank structure 10, thereby greatly improving the stability of the portable outdoor power bank structure 10.

[0036] like Figures 3 to 5As shown, in one embodiment, a first guide slope 11312 is formed on the top of the latching limiting part 1131, and the first guide slope 11312 is disposed away from the sliding part 1132. A second guide slope 1212 adapted to the first guide slope 11312 is formed on the bottom of the latching positioning flange 121. When the user applies a pushing force to the latching positioning flange 121 and pushes it into the first positioning hole 1121, the first guide slope 11312 and the second guide slope 1212 abut and press against each other. The latching limiting part 1131 can retain the force applied by the user through the cooperation of the first guide slope 11312 and the second guide slope 1212. The thrust is decomposed into a lateral thrust in the same direction as the first guide and a longitudinal thrust in the same direction as the thrust applied by the user, so that the latching limiting part 1131 drives the sliding part 1132 to slide along the first guide direction under the push of the lateral thrust until the latching limiting part 1131 is pushed from the first positioning hole 1121 into the guide limiting cavity 1122, so that the user can push the latching positioning flange 121 into the preset position of the first positioning hole 1121, thereby greatly reducing the difficulty of installing the protective cover 120 and the expansion box body 112, and thus greatly improving the ease of use of the portable outdoor power bank structure 10.

[0037] like Figures 3 to 11 As shown, in one embodiment, the latching assembly 113 further includes a pusher 1134. A guide limiting hole 1123 communicating with the guide limiting cavity 1122 is formed on one side of the expansion box body 112 near the opening of the battery mounting slot 111. The sliding part 1132 is disposed opposite to the guide limiting hole 1123. The fixed end of the pusher 1134 passes through the guide limiting hole 1123 and is detachably connected to the sliding part 1132. The fixed end of the pusher 1134 is slidably connected to the hole wall of the guide limiting hole 1123. This not only allows the user to push the sliding part relative to the guide limiting cavity 1122 via the pusher 1134, reducing the difficulty of installing and removing the protective cover 120, but also facilitates the installation and removal of the pusher 1134, greatly reducing the difficulty of replacing and maintaining the pusher 1134, thereby significantly improving the ease of use of the portable outdoor power bank structure 10.

[0038] like Figures 3 to 11As shown, in one embodiment, the pusher 1134 includes a pusher 11341, a fixing part 11342, and a fastener 11343. The pusher 11341 is fixedly connected to the fixing part 11342. The fixing end of the pusher 1134 is located on the side of the sliding part 1132 facing the guide limiting hole 1123 and has a positioning groove 11321 adapted to the fixing part 11342. The fixing part 11342 is engaged in the positioning groove 11321. The bottom of the positioning groove 11321 has a fixing hole 11322 communicating with the positioning groove 11321. The side of the fixing part 11342 adjacent to the fixing hole 11322 has a threaded hole 11 opposite to the fixing hole 11322. 3421, Fastener 11343 is screwed into threaded hole 113421 through fixing hole 11322; Pushing part 11341 is located on the outside of expansion box body 112 so that pusher 1134 can be pre-fixed in positioning groove 11321 through fixing part 11342. This not only greatly reduces the difficulty of aligning threaded hole 113421 and fixing hole 11322, but also effectively prevents fixing part 11342 from shaking or shifting relative to sliding part 1132 during fastening of fastener 11343, avoiding installation misalignment or even misalignment between fixing part 11342 and sliding part 1132, thereby greatly increasing the installation difficulty of pusher 1134.

[0039] like Figure 11 As shown, in this embodiment, the pushing part 11341 and the fixing part 11342 are integrally formed to improve the structural compactness of the pushing part 1134.

[0040] like Figure 1 and Figure 7 As shown, in one embodiment, the outer peripheral wall of the expansion box body 112 is formed with a plurality of plug-in interfaces 1124, which are used to plug into and electrically connect with the plug-in terminals of external electrical devices. In this embodiment, the plug-in interfaces 1124 are existing technologies, such as USB-A plug-in interfaces 1124, DC plug-in interfaces 1124, etc., and will not be described in detail here.

[0041] like Figures 6 to 7As shown, in one embodiment, a snap-fit ​​flange 122 is formed on one side of the protective cover 120 near the opening of the battery mounting slot 111. The snap-fit ​​flange 122 and the snap-fit ​​positioning flange 121 are respectively disposed on both sides of the protective cover 120. The expansion box body 112 is also formed with a snap-fit ​​hole 1125 opposite to the snap-fit ​​flange 122. The snap-fit ​​flange 122 is snapped and fixed in the snap-fit ​​hole 1125, so that the protective cover 120 can be more securely fixed in the preset position of the expansion box body 112 through the cooperation of the snap-fit ​​flange 122 and the snap-fit ​​positioning flange 121. This effectively prevents the battery cell assembly from coming out of the battery mounting cavity 130 due to external factors such as collision or vibration during use, thereby greatly improving the stability of the portable outdoor power supply structure 10.

[0042] like Figures 7 to 8 As shown, in one embodiment, the bottom wall of the battery mounting groove 111 is provided with a positioning flange 1111, and the battery assembly 200 is provided with a second positioning hole 210 opposite to the positioning flange 1111. The positioning flange 1111 is locked and limited in the second positioning hole 210, so that the battery assembly 200 can be reliably positioned in the preset position of the battery mounting cavity 130 by the positioning flange 1111. This effectively prevents the battery cell assembly from colliding or being squeezed against the inner wall of the battery mounting cavity 130 due to external factors such as collision or vibration during use. This greatly reduces the risk of damage or even short circuit caused by collision or squeezing of the battery assembly 200, thereby greatly improving the stability and service life of the battery assembly 200.
