Description

Technical Field

[0001] This utility model relates to an outdoor portable power bank with a retractable protective structure, belonging to the field of outdoor portable power bank technology. Background Technology

[0002] With the increasing popularity of outdoor activities, the demand for portable power supplies in scenarios such as camping, hiking, and adventure is growing. As a key piece of equipment, the safety, durability, and portability of outdoor power banks have become the core demands of users. To cope with the complex outdoor environment, outdoor power banks on the market usually have added protective structures to resist external impacts such as collisions and drops.

[0003] Existing protective structures have many technical defects: First, most protective shells adopt a fixed design, which can provide protection, but increases the overall size and weight of the equipment, making it inconvenient to store and carry, especially in outdoor scenarios where lightweight equipment is required, resulting in a poor user experience; Second, the folding and unfolding operations of some foldable protective structures are cumbersome, lack a reliable automatic reset mechanism, and rely on manual storage, resulting in insufficient ease of use. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides an outdoor portable power bank with a retractable protective structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An outdoor portable power bank with a retractable protective structure includes a power bank body, a base plate on the lower side of the power bank body, a protective shell on the upper side of the base plate, a top plate on the upper side of the protective shell, a corrugated folding plate between the top plate and the base plate, a protrusion on one side of the corrugated folding plate, two tension springs symmetrically arranged on one side of the corrugated folding plate, one end of the tension springs being connected to the upper side of the base plate, and a limiting component for limiting the position of the corrugated folding plate on the upper side of the top plate.

[0007] Through the above technical solution, the base plate provides support for the overall structure, and the protective shell and the top plate form a basic frame. When it is necessary to protect the power supply body, pulling the protrusion unfolds the corrugated folding plate, the tension spring is stretched to generate elastic potential energy, and the limiting component limits and fixes the unfolded corrugated folding plate to form a protective structure surrounding the power supply body; when storing, the limiting component is released, the tension spring contracts and releases potential energy, causing the corrugated folding plate to fold and close between the top plate and the base plate.

[0008] The corrugated folding plate provides protection and storage functions, while the tension spring assists in automatic storage. The limiting component ensures stable protection, effectively protecting the power supply from external impacts. When stored, it saves storage space and improves portability.

[0009] Preferably, the power supply body includes a power supply housing, a power supply module, and an external panel. The power supply housing is disposed on the upper side of the base plate, the power supply module is disposed inside the power supply housing, and the external panel is disposed on one side of the power supply housing and electrically connected to the power supply module. The external panel is close to the corrugated folding plate.

[0010] Through the above technical solution, the power supply housing carries the power supply module, the power supply module provides power output, and the external panel serves as the power output interface and is electrically connected to the power supply module. Furthermore, because it is close to the corrugated folding plate, the external panel is protected when the corrugated folding plate is unfolded.

[0011] The power supply unit has a reasonable structural layout, and the power supply module and the external panel work together to achieve power supply.

[0012] Preferably, the limiting component includes a knob that is rotatably connected to the upper side of the top plate. A limiting strip is provided on one side of the knob, and one side of the limiting strip can abut against one side of the corrugated folding plate. A limiting block for limiting the limiting strip is provided on the upper side of the power supply housing.

[0013] Through the above technical solution, rotating the knob can drive the limiting strip to rotate. When the corrugated folding plate is unfolded, rotating the knob will cause the limiting strip to abut against one side of the corrugated folding plate to achieve the limiting position. The limiting block can cooperate with the limiting strip to fix the position of the limiting strip and prevent it from loosening.

[0014] The limiting component achieves reliable limiting through a mechanical structure. The knob operation is simple and convenient. The limiting strip and the limiting block work together to ensure that the corrugated folding plate is stable and does not shake in the protected state, thus improving the stability of the protective structure.

[0015] Preferably, a guide groove is provided on the side of the protective shell near the corrugated folded plate, and a guide slider is slidably connected in the guide groove, with one side of the guide slider connected to one side of the corrugated folded plate.

[0016] Through the above technical solution, during the unfolding or folding of the corrugated folding plate, the guide slider slides synchronously within the guide groove of the protective shell, thereby constraining and guiding the movement trajectory of the corrugated folding plate.

[0017] The guide groove and guide slider work together to provide motion guidance for the corrugated folding plate, preventing it from deviating or getting stuck during movement, ensuring that the corrugated folding plate unfolds and folds smoothly, and extending the service life of the structure.

[0018] Preferably, a dustproof and breathable plate is provided on one side of the protective shell, and a heat dissipation cavity is provided between the protective shell and the power supply shell.

[0019] Through the above technical solution, the dustproof and breathable plate covers one side of the protective shell, blocking external dust from entering the interior of the protective shell while allowing air circulation; the heat dissipation cavity between the protective shell and the power supply shell forms an air convection channel, promoting heat dissipation.

[0020] The dustproof and breathable plate achieves the dual functions of dust prevention and ventilation, reducing the damage of dust to the internal components of the power supply; the heat dissipation cavity enhances air circulation efficiency, improves the heat dissipation effect of the power supply, and avoids high temperature affecting the power supply performance.

[0021] Preferably, a plurality of heat-conducting strips are provided on the lower side of the top plate, and one side of the heat-conducting strips abuts against one side of the power supply housing.

[0022] Through the above technical solution, the heat-conducting strip on the lower side of the top plate is in close contact with one side of the power supply housing, so that the heat generated by the power supply housing during operation is conducted to the top plate through the heat-conducting strip, and then dissipated to the outside by the top plate.

[0023] The heat-conducting strip enhances the heat exchange efficiency between the power supply casing and the outside environment, accelerates heat dissipation, effectively reduces the power supply's operating temperature, and ensures the stability and safety of the power supply during long-term outdoor use.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] This utility model constructs a stable support frame through a base plate, a protective shell, and a top plate. The foldable nature of the corrugated folding panel allows for flexible switching of the protective structure. When unfolded, it forms a surrounding protective barrier, effectively resisting damage from outdoor bumps, impacts, and other external forces. Symmetrically arranged tension springs utilize elastic potential energy to automatically retract and reset the corrugated folding panel, reducing the intensity of manual operation. Limiting components precisely lock the unfolded state of the corrugated folding panel, preventing structural loosening during protection. It balances the reliability of protection with the convenience of storage, significantly improving the durability and portability of the product for outdoor use.

[0026] This utility model utilizes a limit assembly that achieves multi-level limiting through the mechanical cooperation of a knob, a limit strip, and a limit block. The knob's rotary operation is simple and intuitive, conforming to user operating habits. The contact limiting between the limit strip and the corrugated folding plate ensures precise structural positioning. The synergistic effect of the limit block and the limit strip effectively prevents the limit strip from rotating unexpectedly due to vibration or collision, thus avoiding structural failure. The overall mechanical limiting structure is independent of electronic components, adapting to complex outdoor environments such as high and low temperatures and humidity, thereby improving limiting reliability and structural durability.

[0027] In this invention, the sliding cooperation between the guide groove and the guide slider provides rigid motion trajectory constraints for the corrugated folding plate, ensuring that it moves smoothly along a preset path during unfolding or folding, avoiding skewing, jamming, or structural deformation caused by uneven force. The tight fit between the slider and the groove reduces movement gaps, reduces component wear, and extends the service life of the corrugated folding plate. At the same time, it ensures the consistency of the folding structure's movement, improving the smoothness of user operation and the product's user experience. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-4 This utility model provides a technical solution:

[0036] An outdoor portable power bank with a retractable protective structure features a base plate made of rigid plastic, laid flat and sized to fit the power bank body, providing stable support for the entire device. The protective shell is a rectangular shell made of ABS engineering plastic, possessing a certain strength and impact resistance. Its lower side is bolted to the upper edge of the base plate, forming the basic protective frame of the device. The top plate, also a rectangular plate structure made of the same material as the protective shell, covers the upper side of the protective shell and is secured with clips, forming the outer protective structure of the device together with the base plate and protective shell.

[0037] A corrugated folding plate is installed between the top plate and the bottom plate. The corrugated folding plate is made of elastic metal material with evenly distributed V-shaped corrugations. It can be flexibly unfolded and folded in the vertical direction. When unfolded, it can surround the power supply body to form a closed protective barrier, effectively resisting external collisions.

[0038] A protrusion is welded to the center of one side of the corrugated folding panel. The surface of the protrusion has anti-slip textures, making it easy for users to manually pull the corrugated folding panel to unfold. On the side of the corrugated folding panel near the bottom plate, two tension springs are installed symmetrically in parallel. One end of the tension spring is fixed to the corrugated folding panel by a hook, and the other end is connected to a pre-set hanging ring on the upper part of the bottom plate by a hook. When the corrugated folding panel is unfolded, the tension spring is in a stretched state, generating an elastic restoring force, which facilitates subsequent storage and repositioning. A limit component is installed in the center of the upper side of the top plate to limit and fix the unfolded corrugated folding panel.

[0039] The power supply unit includes a power supply housing, a power supply module, and an external panel. The power supply housing is made of insulating and flame-retardant material and has a rectangular structure. Its lower side is fixed to the upper center of the base plate with screws to provide protection for the internal components.

[0040] The power supply module is located inside the power supply housing and is fixed to the bottom of the housing cavity with bolts. It consists of a lithium battery pack and a control circuit board, realizing the storage and output control of electrical energy.

[0041] The external panel is located on one side wall of the power supply housing and is electrically connected to the control circuit board of the power supply module via wires. The panel integrates components such as a USB interface, a Type-C interface, and a power switch.

[0042] The limiting component includes a knob, a limiting strip, and a limiting block. The knob is made of plastic and has a cylindrical structure. Its lower end is rotatably connected to a pre-set mounting hole in the upper center of the top plate via a bearing. The upper end of the knob has an anti-slip edge for easy operation by the user.

[0043] The limiting strip is a long metal strip structure, with one end vertically welded to the lower side of the knob. It rotates synchronously with the knob, and the other side of the limiting strip can abut against one side of the corrugated folding plate to limit the corrugated folding plate.

[0044] Two limit blocks are provided on the upper side of the power supply housing corresponding to the position of the limit strip. The limit blocks are plastic boss structures, and a limit groove is formed between the two limit blocks. When the limit strip rotates to abut the corrugated folding plate, the limit strip is locked into the limit groove. The limit blocks limit the limit strip to prevent it from rotating accidentally due to vibration or other reasons.

[0045] Guide grooves are provided on the inner walls of the two sides of the protective shell near the corrugated folded plate. The guide grooves extend vertically and the width of the grooves is adapted to the guide sliders. The guide sliders are rectangular block structures made of wear-resistant plastic and are slidably connected in the guide grooves. One side of the guide sliders is fixedly connected to the two edges of the corrugated folded plate by screws.

[0046] When the corrugated folding plate is unfolded or retracted, the guide slider slides synchronously along the guide groove, precisely constraining the movement trajectory of the corrugated folding plate to ensure its smooth and stable movement.

[0047] A rectangular mounting opening is provided on one side wall of the protective shell, and a dustproof and breathable plate is fixedly installed inside the mounting opening. The dustproof and breathable plate adopts a composite structure of metal mesh and non-woven fabric, which can effectively block outdoor wind, sand and dust from entering the interior of the protective shell, while ensuring air circulation.

[0048] A 5-8mm gap is reserved between the protective shell and the power supply shell to form a heat dissipation cavity. The heat dissipation cavity is connected to the dustproof and ventilated plate, and the heat generated during the operation of the power supply is accelerated by air convection.

[0049] Several heat-conducting strips are evenly spaced on the lower side of the top plate. The heat-conducting strips are made of copper and have good thermal conductivity. One end of the heat-conducting strip is attached to the lower side of the top plate with thermally conductive silicone, and the other end is in close contact with the upper surface of the power supply housing. This allows the heat from the power supply housing to be quickly conducted to the top plate and then dissipated to the external environment from the top plate, thus improving the heat dissipation efficiency of the equipment.

[0050] The workflow of this embodiment is as follows: When the protection function is required, the user pulls the corrugated folding plate upward through the protrusion, the tension spring is stretched, the guide slider slides upward along the guide groove, and after the corrugated folding plate is fully unfolded, the knob is turned to drive the limit strip to rotate, so that the limit strip abuts against the corrugated folding plate and is locked into the limit groove between the limit blocks, thus completing the protection state locking.

[0051] When storage is needed, turn the knob in the opposite direction to release the limit, the tension spring will contract and drive the corrugated folding plate to fold and store automatically, and the guide slider will slide down the guide groove to reset.

[0052] This specific implementation method achieves flexible storage and reliable protection of the protective structure through reasonable structural design, while also taking into account functions such as heat dissipation and dust prevention, significantly improving the practicality and durability of outdoor portable power banks.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
