Description

Technical Field

[0001] This utility model relates to the field of charger protection technology, and in particular to a lithium battery charger sheath. Background Technology

[0002] Currently, there are various types of lithium battery charger sleeves on the market. These sleeves provide protection for lithium battery chargers to a certain extent. Some sleeves, through the design of protective structures, can effectively reduce the impact and scratches that the charger suffers during transportation and use, thereby extending the charger's service life.

[0003] However, the existing lithium-ion charger structure made of metal profile shell has obvious defects. When the core is working, the temperature of the profile shell is close to 70°C. When the metal temperature exceeds 50°C, it will be obviously hot to the touch, and direct contact can easily cause burns. At the same time, the metal shell lacks an effective heat dissipation structure and its heat dissipation efficiency is low. In addition, the metal shell has a monotonous appearance, lacks aesthetics, and cannot improve its texture through surface treatment processes. Utility Model Content

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1 to 4 This utility model provides a lithium battery charger cover, including a plastic top cover 1, a profile top cover 2, a PCB board 3, a profile bottom shell 4, and a plastic bottom cover 5. The outer side of the plastic top cover 1 and the outer side of the plastic both have a grid pattern 6 and a grid structure. One end of the PCB board 3 is provided with an output line 7, and the other end of the PCB board 3 is provided with an input line 8. The plastic top cover 1 is closed and positioned directly above the plastic bottom cover 5. The profile top cover 2 is fixed to the inner top of the plastic top cover 1 by a top fixing member. The PCB board 3 is fixed to the inner top of the profile top cover 2 by an internal fixing member. The output line 7 and the input line 8 extend from the two ends of the plastic top cover 1 and the plastic bottom cover 5, respectively. The profile bottom shell 4 is fixed to the inner bottom of the plastic bottom cover 5 by a bottom fixing member, and the profile top cover 2 abuts against the outer edge of the profile bottom shell 4.

[0019] In this embodiment, the dual goals of efficient heat dissipation and safety protection are achieved through layered arrangement and material optimization. The grid-like grooves 6 and lattice structure on the outer sides of the plastic upper cover 1 and plastic lower cover 5 significantly increase the heat dissipation area, and the non-metallic material effectively reduces the surface temperature, avoiding the risk of burns from human touch. The profile upper cover 2 and the bottom shell are made of metal to ensure structural strength, and are isolated from the plastic parts by fasteners to reduce heat conduction. The PCB board 3 is suspended and installed inside the top of the profile upper cover 2 by internal fasteners, further preventing the heat from the mechanism from being directly transferred to the outer shell, thus improving overall safety.

[0020] Furthermore, a locking block 9 is provided at the outer edge of the plastic upper cover 1, and a locking ring 10 is provided at the outer edge of the plastic lower cover 5. The plastic upper cover 1 is fitted and positioned directly above the plastic lower cover 5 by the locking block 9 and the locking ring 10.

[0021] In this embodiment, mechanical interlocking replaces traditional bonding or complex fixing methods, simplifying the assembly process and enhancing sealing performance.

[0022] Furthermore, the top fixing component is a plurality of M4 screws 11, the bottom fixing component is a plurality of M4 stepped screws 12, a plurality of silicone rubber pads 13 are provided below the plastic lower cover 6, and each silicone rubber pad 13 covers the corresponding stepped screw 12, and the internal fixing component is a plurality of M3 screws 14.

[0023] In this embodiment, the M4 screw 11 achieves a stable connection between the profile cover 2 and the plastic cover 1. The M4 stepped screw 12 acts as an anti-slip pad through the silicone rubber pad 13, while also covering the screw hole of the M4 stepped screw 12 to improve the appearance and prevent dust from entering from the bottom.

[0024] Furthermore, a left cover 16 is provided at one end of the profile upper cover 2 and the profile bottom shell 4 via a left self-tapping screw 15. The left cover 16 has an LED light hole 17, and an LED light cap 18 is provided inside the LED light hole 17. The output line 7 also passes through the left cover 16. A right cover 20 is provided at the other end of the profile upper cover 2 and the profile bottom shell 4 via a right self-tapping screw 19. The data input line 8 also passes through the right cover 20.

[0025] In this embodiment, self-tapping screws facilitate quick assembly and disassembly, making it easy to maintain internal components. The LED light hole 17 on the left side cover 16 clearly displays the charging status, and the light cap is made of translucent plastic material to avoid structural weakening caused by openings in the metal shell. The output line 7 and the input line 8 are respectively led out through the left and right side covers 20, and the cable fixing groove design prevents repeated bending and damage. At the same time, the rounded corners of the side cover edges are consistent with the style of the plastic shell, improving the overall aesthetics of the product.

[0026] Furthermore, a Mylar sheet 21 is provided between the PCB board 3 and the profile, and the Mylar sheet 21 is also located between the plurality of M3 screws 14.

[0027] In this embodiment, the Mylar sheet 21 is used as an insulating layer to bond the PCB board 3. Its high temperature resistance (can withstand temperatures above 120°C) effectively blocks the heat from the mechanism from being conducted to the upper cover 2 of the profile.

[0028] In this invention, the left and right covers are connected to the two ends of the lower profile cover using self-tapping screws. Then, adhesive is applied to the inside of the left and right covers, ensuring the adhesive application does not extend beyond the upper edge of the lower profile cover while maintaining a clean appearance. The Mylar sheet is then attached to the bottom of the profile, with the bend on the output side. The PCB board is then fixed inside the bottom of the profile cover using M3 screws, ensuring the LEDs align with their corresponding LED holes. The PCB board is then coated with polyurethane adhesive. After the upper profile cover is snapped into place with the bottom profile cover, the left and right covers are connected using self-tapping screws to secure the upper profile cover. The plastic upper cover is then snapped into place with the plastic lower cover. M4 screws and M4 stepped screws are used to secure the plastic upper and lower covers to the mechanism. The silicone rubber pad is then aligned with the corresponding screw holes on the plastic lower cover. At this point, the protective sleeve can be safely connected to the power supply and the device for charging.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
