Description

Technical Field

[0001] This utility model relates to the field of battery packaging technology, specifically to a plastic packaging box for batteries. Background Technology

[0002] With the development of battery packaging technology, various battery packaging structures have been widely adopted in practical applications. However, some problems still exist in actual use. For example, the plastic battery packaging boxes currently on the market generally lack sufficient safety, especially for children. The existing packaging box structures are relatively simple, and the opening mechanisms lack protective designs, making them easy for children to open, leading to the accidental removal or ingestion of small batteries, creating safety hazards. In addition, the existing packaging boxes have poor sealing and cushioning performance, making it difficult to effectively protect batteries from external impacts or vibrations during transportation and storage, increasing the risk of battery damage or leakage.

[0003] In the prior art, a battery packaging package uses a cardboard box structure and employs a weakened seam design to enable a tear-open top, facilitating quick removal of the internal tray and batteries. However, while this design improves accessibility, it also reduces the overall sealing of the packaging, particularly lacking effective anti-opening measures, especially in the face of children. Furthermore, the packaging lacks any cushioning or securing structures, failing to provide adequate shock absorption protection for the internal batteries, thus making them susceptible to damage from impacts during transportation.

[0004] One battery packaging design offers a housing structure with a resealable opening to maintain spacing between batteries and allow for sequential access. However, the opening mechanism remains relatively simple and lacks child safety features, posing a risk of accidental opening by a child. Furthermore, the packaging relies primarily on the outer casing for protection, lacking independent containment structures for individual batteries. This could lead to battery collisions during severe vibrations, potentially causing short circuits or leakage. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model proposes a plastic packaging box for batteries.

[0006] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

[0007] A plastic packaging box for batteries includes an outer box body, an inner bracket, and a protective assembly. The outer box body is a rectangular shell structure with an open top. The inner bracket is provided inside the outer box body and is slidably connected to both sides of the inner wall of the outer box body via slide rails. The top surface of the inner bracket has several independent battery receiving slots. The inner wall of each battery receiving slot is provided with a flexible cushioning pad, and a limiting protrusion integrally formed with the bottom center of each battery receiving slot is fixed therewith. The top of the limiting protrusion is arc-shaped and fits against the bottom of the battery. A sealing assembly is provided on the top of the outer box body. The sealing assembly includes an upper cover plate and a locking mechanism. The upper cover plate is rotatably connected to the rear end of the outer box body via a hinge. The protective assembly is disposed around the inside of the outer box body and leaves a gap between it and the outer wall of the inner bracket. The protective assembly includes a cushioning airbag and a guide tube. The cushioning airbag is fixed around the inner wall of the outer box body and communicates with the guide tube. The guide tube passes through the bottom of the outer box body and communicates with the outside. An air valve is provided at the end of the guide tube.

[0008] A further preferred embodiment: the slide rail consists of two parallel tracks with a T-shaped cross-section, and the inner bracket has grooves on both sides that match the tracks. The grooves are slidably connected to the tracks, and the inner walls of the grooves are coated with a wear-resistant coating.

[0009] A further preferred embodiment: the flexible cushioning pad is made of silicone material.

[0010] A further preferred embodiment: a magnetic sheet is embedded inside the limiting protrusion, and the magnetic sheet is magnetically attracted to the bottom of the battery.

[0011] A further preferred embodiment: the buffer airbag is provided with several separator membranes inside, the separator membranes divide the buffer airbag into multiple independent small air chambers, and the small air chambers are connected to each other through micropores.

[0012] Compared with existing technologies, the beneficial effects are:

[0013] 1. By using the limiting protrusions on the inner bracket to adhere to the bottom of the battery and employing magnetic adsorption, combined with the shock absorption effect of the flexible buffer pad, the risk of batteries shifting or being damaged due to vibration or collision during transportation can be effectively avoided, significantly improving the safety and stability of the battery; 2. The buffer airbag in the protective component forms multiple independent small air chambers through the separator membrane, which can absorb external impact during transportation, and regulate the internal air pressure of the airbag through the guide tube and air valve, thereby effectively protecting the battery from severe vibration or impact and improving the overall protective performance of the packaging box.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] A plastic packaging box for batteries includes an outer box body 1, an inner bracket 2, and a protective assembly. The outer box body 1 is a rectangular shell structure with an open top for accommodating the inner bracket 2 and the protective assembly. The inner bracket 2 is slidably connected to both sides of the inner wall of the outer box body 1 via slide rails 3, thereby enabling a pull-out function. Several independent battery receiving slots 4 are formed on the top surface of the inner bracket 2. Each battery receiving slot 4 has a flexible buffer pad 5 on its inner wall, and a limiting protrusion 6 is fixed at the center of the bottom of each battery receiving slot 4. The top of the limiting protrusion 6 is arc-shaped and fits against the bottom of the battery. A magnetic sheet 7 is embedded inside the limiting protrusion 6 to enhance the adsorption stability of the battery. A sealing assembly is provided on the top of the outer box body 1, including an upper cover plate 8 and a locking mechanism. The upper cover plate 8 is rotatably connected to the rear end of the outer box body 1 via a hinge, and the locking mechanism is symmetrically distributed on both sides of the front end of the outer box body 1. The protective components are located around the inside of the outer box 1 and have a gap between them and the outer wall of the inner bracket 2. The protective components include a buffer airbag 17 and a guide tube 18. The buffer airbag 17 is fixed around the inner wall of the outer box 1 and is connected to the guide tube 18. The guide tube 18 passes through the bottom of the outer box 1 and is connected to the outside. An air valve 20 is provided at the end of the guide tube 18.

[0018] The slide rail 3 consists of two parallel tracks with a T-shaped cross-section. The inner bracket 2 has grooves on both sides that match the tracks. These grooves slide smoothly into the tracks, and their inner walls are coated with a wear-resistant coating. The design of the slide rail 3 not only ensures stable sliding of the inner bracket 2 within the outer casing 1 but also improves the durability of the grooves through the wear-resistant coating, reducing wear caused by friction during long-term use. This structure allows the inner bracket 2 to be easily pulled out or pushed in from the outer casing 1, facilitating quick battery access for users.

[0019] The flexible buffer pad 5 of the battery housing 4 is made of silicone material with a thickness of 2mm to 3mm. Several hemispherical protrusions, each with a diameter of 1mm to 2mm, are evenly distributed on the surface of the flexible buffer pad 5. This design provides initial shock absorption protection when the battery is subjected to external vibration or impact. The hemispherical protrusions also increase the contact area, further enhancing the cushioning effect. The limiting protrusion 6 has a height of 5mm to 8mm, and its arc-shaped top contacts the bottom of the battery, accounting for 30% to 40% of the total bottom area of ​​the battery. A magnetic sheet 7 is embedded inside the limiting protrusion 6, magnetically adsorbing onto the bottom of the battery. This design not only achieves precise battery positioning but also enhances the battery's stability during transportation through magnetic adsorption, avoiding the risk of battery displacement or damage due to vibration or collision.

[0020] The buffer airbag 17 has several separator membranes inside, dividing it into multiple independent small air chambers that are connected by micropores. This design, using separator membranes 19 to form multiple independent small air chambers, significantly enhances the buffering performance. The outer wall of the guide tube 18 is covered with an insulation layer made of polyurethane foam, with a thickness of 1mm to 2mm. The opening pressure of the air valve 20 at the end of the guide tube 18 is 0.02MPa to 0.05MPa. During transportation, when there is a large external impact, the buffer airbag 17 is compressed, and gas enters the guide tube 18 through the micropores from the small air chambers and exits through the air valve 20. When the impact disappears, external air re-enters the buffer airbag 17 through the air valve 20, restoring its initial state. This design effectively absorbs external impact and protects the battery from severe vibration or impact by regulating the internal air pressure of the airbag.

[0021] The upper cover plate 8 in the sealing assembly is rotatably connected to the outer box body 1 via a hinge. When closed, the upper cover plate 8 covers the top opening of the outer box body 1, ensuring the overall sealing of the packaging box. The locking mechanism enhances the sealing and security of the packaging box.

[0022] The working principle is as follows:

[0023] In practical applications, such as e-commerce logistics transportation scenarios, operators first pull the inner tray 2 out of the outer box 1 via the slide rail 3, and then place the batteries one by one into the battery receiving slots 4 on the inner tray 2. The flexible buffer pad 5 provides initial shock absorption protection for the batteries, and the limiting protrusion 6, through its arc-shaped top, adheres to the bottom of the battery and is attracted by the magnetic sheet 7, achieving precise positioning and enhanced stability of the batteries. Subsequently, the operator pushes the inner tray 2 back into the outer box 1, closes the top cover 8, and locks it using the locking mechanism. During transportation, when the packaging box is subjected to external impact, the buffer airbag 17 in the protective assembly absorbs the impact force through the small air chamber formed by the separator membrane 19. The gas is discharged through the guide tube 18 and the air valve 20, effectively protecting the batteries from vibration or impact. When the impact force disappears, external air re-enters the buffer airbag 17 through the air valve 20, restoring its initial state.
