Description

Technical Field

[0001] This utility model relates to the field of outdoor intelligent equipment technology, and in particular to a battery swapping structure, a battery replacement leg tube, and an electric tent. Background Technology

[0002] With rapid economic and social development, people's material living standards have significantly improved, and their pursuit of spiritual enrichment has also grown. Amidst fierce social competition and increasing life pressures, people increasingly yearn for relaxation and connection with nature. Therefore, outdoor activities, with their advantages of escaping urban hustle and bustle and connecting with nature, have transformed from niche, professional activities into a popular form of leisure and entertainment.

[0003] At the same time, the outdoor equipment industry has also flourished. From camping tents and outdoor cooking equipment to essential tables and chairs, smart outdoor devices, with their intelligent features, have brought users a brand-new experience through automated mechanical structures or intelligent control, and have been enthusiastically received by the market, especially electric tents. Electric tents typically use a power structure to assist in setup and are equipped with convenient lighting equipment; these functions all rely on battery packs for power.

[0004] However, existing electric tents have some issues with battery component design. Some electric tents have separate battery components, not integrated into the tent structure. This not only affects aesthetics but also adds extra connection steps, making the setup process more cumbersome. Other electric tents, while incorporating the battery components into the frame structure, suffer from poor design, making battery replacement difficult.

[0005] Therefore, there is an urgent need in the market for a new type of electric tent that can solve the problems of low integration between the battery components and the tent structure, as well as the inconvenience of battery replacement in existing electric tents. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a battery swapping structure, a battery replacement leg tube, and an electric tent, so as to solve the problems of low integration between the battery component and the tent structure and inconvenient battery replacement in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model provides a battery swapping structure for accommodating a battery assembly, comprising:

[0008] A protective housing, the protective housing including a receiving cavity and a power swapping opening communicating with the receiving cavity;

[0009] The battery compartment contains the battery assembly and is hinged to the inner wall of the protective housing. The battery compartment rotates around the hinge point between itself and the protective housing and switches between a storage position and a battery swapping position. In the storage position, the battery compartment is stored in the receiving cavity. In the battery swapping position, the battery compartment can be removed from the battery swapping opening.

[0010] A protective cover adapted to the battery swapping opening, one end of which is hinged to the edge of the battery swapping opening, and the protective cover can rotate around the edge of the battery swapping opening;

[0011] A connecting rod, one end of which is hinged to the protective cover and the other end of which is hinged to the battery compartment. When the protective cover is opened, the connecting rod drives the battery compartment to rotate to the battery swapping position. When the protective cover is closed, the connecting rod drives the battery compartment to rotate to the storage position.

[0012] As a more preferred approach, at the battery swapping location, a portion of the battery compartment extends from the battery swapping opening.

[0013] The protective housing includes a fixed cover, which is disposed on one side of the battery swapping opening. The battery compartment is hinged to the bottom of the fixed cover and close to the edge of the battery swapping opening to facilitate the rotation path of the battery compartment. The accommodating cavity has sufficient space to allow the battery compartment to extend out of the battery swapping opening by rotation.

[0014] As a more preferred approach, the battery compartment is hinged to the fixed cover via a first hinge structure.

[0015] As a more preferred embodiment, the first hinge structure includes a hinge protrusion disposed on the battery compartment, a fixing protrusion disposed on the bottom of the fixing cover, and a pin. The hinge protrusion and the fixing protrusion are respectively provided with pin holes. The battery compartment and the fixing cover are hinged by passing the pin through the corresponding pin holes on the hinge protrusion and the fixing protrusion.

[0016] As a more preferred approach, the protective cover is hinged to the edge on the other side of the battery swapping opening to provide a sufficient angle, allowing the protective cover to switch the battery compartment between the storage position and the battery swapping position by opening and closing using the connecting rod, thus avoiding interference between the connecting rod and the protective housing during the opening and closing of the protective cover.

[0017] As a more preferred embodiment, the battery swapping structure further includes an elastic element, the two ends of which are connected to the fixed cover and the battery compartment, respectively. The elastic element applies a driving force to the battery compartment to move toward the storage position. Thus, when the protective cover opens and closes, causing the battery compartment to move to the swapping position and completing the battery replacement, the elastic element can pull the battery compartment to the storage position, and at the same time, drive the protective cover to close via the connecting rod, avoiding the problem of forgetting to close the protective cover after replacing the battery.

[0018] As a more preferred approach, a magnetic clasp is provided at the other end and / or the middle of the side of the protective cover, and a corresponding magnetic element adapted to the magnetic clasp is provided at the corresponding position of the protective housing. When the protective cover is closed, the protective housing magnetically attracts the protective cover through the magnetic element. In this way, when the protective cover is closed, the magnetic attraction of the protective cover prevents it from loosening and shaking, and prevents the protective cover from being opened by strong winds or other external forces, which would interfere with the operation of the battery assembly. The structure is more compact and the safety is improved.

[0019] To solve the above problems, this utility model also provides a battery replacement pin tube, comprising:

[0020] Leg tube body;

[0021] The aforementioned battery swapping structure is disposed within the foot tube body;

[0022] A battery assembly disposed within the battery compartment.

[0023] As a more preferred approach, the battery swapping structure is vertically mounted on the side wall of the foot tube body, with the edge of the swapping opening hinged to the protective cover facing upwards. In this way, when the protective cover is closed, it hangs downwards, making the protective cover more stable and less likely to be opened. This avoids the risk of the protective cover opening or closing due to gravity when closed, thus exposing the battery compartment.

[0024] To solve the above problems, this utility model also provides an electric tent, including: a plurality of the above-mentioned battery replacement leg tubes.

[0025] As described above, the battery swapping structure, battery replacement leg tube, and electric tent of this utility model have the following beneficial effects: When the battery needs to be replaced, the protective cover is opened, and the connecting rod drives the battery compartment to rotate to the swapping position. The battery compartment can be taken out from the swapping opening, making it convenient to put in and take out the battery assembly to complete the battery replacement. After the battery replacement is completed, the protective cover is closed, and the connecting rod drives the battery compartment to rotate to the storage position. The battery compartment is stored in the receiving cavity, and the battery assembly can be better protected, avoiding external environmental interference, such as rainwater.

[0026] When the battery replacement foot tube of this utility model is used as a support for smart devices, it is equipped with a battery swapping structure. Various smart devices can directly draw power through the battery components inside the battery replacement foot tube. By opening the protective cover, the battery compartment can be extended from the swapping opening, making it easy to put in and take out the battery components and complete the battery replacement. At the same time, the hidden design ensures the system integration and aesthetics of the smart devices.

[0027] The electric tent of this utility model uses the above-mentioned battery replacement leg tube as a support structure, and integrates the battery assembly directly into the support structure. At the same time, opening the protective cover allows the battery compartment to extend, which also ensures the convenience of battery replacement, thus taking into account both system integration and the convenience of battery replacement.

[0028] This utility model's battery swapping structure, battery replacement leg tube, and electric tent, through the linkage design of the protective cover and battery compartment, and the integration of the support structure and battery swapping structure, takes into account both system integration and the convenience of battery replacement, solving the problems of low integration between battery components and tent structure and inconvenient battery replacement in existing electric tents.

Strong winds or other external forces can open the protective cover 13 and interfere with the operation of the battery assembly 2. The structure is more compact and the safety is improved.

[0076] To solve the above problems, such as Figure 5 as well as Figure 6 As shown, this utility model also provides a battery replacement pin tube, comprising:

[0077] Leg tube body 3;

[0078] The battery swapping structure 1 described above is disposed within the foot tube body 3;

[0079] Battery assembly 2, which is disposed within the battery compartment 12.

[0080] To better illustrate the battery replacement foot tube of this utility model, the following specific application will be used as an example: When the battery replacement foot tube of this utility model is used as a support for smart devices, it is equipped with a battery swapping structure 1. Various smart devices can directly draw power from the battery assembly 2 inside the battery replacement foot tube. By opening the protective cover 13, the battery compartment 12 can extend from the swapping opening 111, making it easy to put in and take out the battery assembly 2 and complete the battery replacement. At the same time, the hidden design ensures the system integration and aesthetics of the smart device.

[0081] In some embodiments of this utility model, such as Figure 5 as well as Figure 6 As shown, the battery swapping structure 1 is vertically arranged on the side wall of the foot tube body 3, and the edge of the swapping opening 111, which is hinged to the protective cover 13, is arranged upward. In this way, when the protective cover 13 is closed, it hangs downward. In this state, the protective cover 13 is more stable and less likely to be opened, avoiding the risk of the protective cover 13 being opened or closed due to gravity when closed, thus exposing the battery compartment 12.

[0082] To solve the above problems, this utility model also provides an electric tent, including: a plurality of the above-mentioned battery replacement leg tubes.

[0083] To better illustrate the electric tent of this utility model, the following specific application will be used as an example. The electric tent of this utility model uses the aforementioned battery replacement leg tube as a support structure, directly integrating the battery assembly 2 within the support structure. Simultaneously, opening the protective cover 13 reveals the protruding battery compartment 12, ensuring convenient battery replacement. This approach balances system integration and battery replacement convenience. It can be seen that the battery swapping structure, battery replacement leg tube, and electric tent of this utility model, through the coordinated design of the protective cover 13 and the battery compartment 12, and the integration of the support structure and the battery swapping structure 1, balance system integration and battery replacement convenience, solving the problems of low integration between the battery assembly 2 and the tent structure, and inconvenient battery replacement in existing electric tents.
