The bottom shell 1 is provided with a window 10, and the window 10 is fixedly installed with a transparent protective sheet 11. The window 10 is located on the opposite side of the fixing frame 8. The fixing frame 8 is fixedly installed with a display 13 by a buckle 12. The battery pack 7 includes 5 cylindrical lithium batteries 14. The transparent protective sheet 11 is made of transparent resin. The bottom shell 1 is provided with an anti-slip rubber strip 15.

[0023] Through the above technical solution, the utility model includes a bottom shell 1 and an upper shell 2. The upper shell 2 is provided with a plug-in shell 3. The plug-in shell 3 is used to plug in and match the power tool or charger so that the utility model is fixed on the power tool or charger. The plug-in shell 3 is extended with an anti-confusion block 4. The anti-confusion block 4 is a raised structure. The anti-confusion block 4 is arranged on one side of the plug-in shell 3. The anti-confusion block 4 can prevent the power tool battery from being inserted into the power tool or charger with an unmatched signal, thereby preventing the battery, power tool and charger from burning and eliminating safety hazards.

[0024] The plug-in shell 3 of the present invention is asymmetrically provided with five electrical terminals 5, which are used to connect to power tools or chargers to realize power transmission during the charging and discharging process. The asymmetrical arrangement of the electrical terminals 5 makes it easy for users to quickly identify the type of tool battery, so as to determine the type of power tool or charger, reduce the mixed insertion of tool batteries with different types of power tools or chargers, and improve the safety factor.

[0025] Example 2:

[0026] like Figure 1-Figure 7As shown, the present invention comprises two main parts: a base shell 1 and an upper shell 2. These two parts are fastened together by bolts, ensuring the overall structural stability of the battery. A connector housing 3 is located on top of the upper shell 2. This connector housing 3 allows for secure connection to a power tool or charger, ensuring the battery remains securely connected. The design of this connector housing 3 not only provides a physical connection but also, more importantly, provides a stable power transmission path to ensure proper function. The connector housing 3 is an integral extension of the upper shell 2 and is equipped with an anti-confusion block 4, the core component of the present invention. This block 4, located on one side of the connector housing 3, primarily prevents the battery from being inserted into an incompatible power tool or charger. Since power tools and chargers may vary in model, charging voltage, and output voltage, the presence of this block 4 effectively prevents the battery from connecting to an incompatible device, thereby preventing the risk of burns to the battery, power tool, or charger. This design eliminates the safety hazards associated with interface confusion and improves overall user safety. To further enhance identification and safety, the plug-in housing 3 is equipped with five electrical terminals 5 arranged in an asymmetrical pattern. These terminals 5 connect to a power tool or charger, enabling power transfer during charging and discharging. The asymmetrical arrangement of the terminals 5 makes it easier for users to identify the battery type and determine the appropriate power tool or charger. This asymmetrical layout not only avoids potential confusion during use but also helps users quickly and accurately select the appropriate device. The battery's bottom housing 1 and top housing 2 are secured together by a middle housing 6. A mounting bracket 8 is provided at one end of the middle housing 6, which is used to mount a display 13 and stabilize the battery pack 7. The middle housing 6 is equipped with a top post 9, which securely connects the middle housing 6 to the top housing 2. This ensures that the middle housing 6 firmly presses and secures the battery pack 7, ensuring stability during use. The bottom housing 1 has a window 10, to which a transparent protective plate 11 is fixedly mounted. The transparent protective cover 11 works in conjunction with the display 13 to clearly display battery status information. This design, through multiple optimizations, avoids safety hazards caused by interface confusion. The anti-confusion block 4 and asymmetrical arrangement of electrical terminals 5 not only enhance safety but also improve the user experience. The integrated design of the bottom shell 1, upper shell 2, middle shell 6, and transparent protective cover 11 ensures the stability and reliability of the battery during actual use.

[0027] The window 10 of the present invention is located on the opposite side of the mounting bracket 8, allowing the user to conveniently view the display 13 through the window 10. The mounting bracket 8 is a crucial component of the battery's internal structure, securing the display 13 and ensuring its secure placement and stability within the battery. The display 13 is connected to the mounting bracket 8 via a clip 12. This clip 12 ensures a secure fit and prevents displacement or detachment during battery use. The display 13 displays important data such as the tool battery's charge level, temperature, and operating current. This information is crucial for users to understand the battery's operating status and perform necessary maintenance. The charge level display helps users understand the remaining battery charge, allowing them to determine when charging is necessary to avoid running out of power during use. The temperature display provides battery temperature data during use, helping users promptly identify and address potential overheating issues. The operating current display allows users to understand the battery's actual current output during use, ensuring that power transfer between the battery and the power tool remains within a safe range. The transparent protective sheet 11 not only protects the display 13, but also prevents damage to the display 13 caused by external environmental factors. In this way, the user can obtain the operating status of the battery at any time and make corresponding adjustments in a timely manner to ensure that the battery maintains optimal performance under various operating conditions. The fixing method of the fixing frame 8 through the buckle 12 ensures the stability of the display 13 inside the battery and prevents the display 13 from shifting or being damaged in the event of vibration or impact. This buckle 12 design not only simplifies the installation and maintenance process of the display 13, but also enhances its reliability in actual use. All functional modules of the display 13 have undergone rigorous testing to ensure their accuracy and stability in long-term use. Users can rely on this displayed information to make correct usage decisions.

[0028] The battery pack 7 of the present invention comprises five cylindrical lithium batteries 14. These batteries are arranged in a straight line and fixed within the base housing 1, forming the core of the battery. The selection and application of cylindrical lithium batteries 14 play a crucial role in the design of the battery pack 7 because they offer excellent electrical performance and stability, enabling them to provide a reliable power supply for power tools. The primary advantage of cylindrical lithium batteries 14 lies in their high energy density, meaning they can store more energy in a relatively small volume. This characteristic enables the battery pack 7 to deliver a large amount of power within a relatively small space, thereby enhancing the power tool's endurance. Cylindrical lithium batteries 14 also have a long service life and high cycle stability, allowing them to maintain high performance and low degradation rates during multiple charge and discharge cycles. The stability and safety of the battery pack 7 are also key considerations in its design. To ensure that the battery pack 7 maintains good performance under various operating conditions, the battery pack 7 is equipped with internal protection circuits that monitor the battery's voltage, temperature, and charge and discharge status to prevent potential battery damage, such as overcharging, overdischarging, or overheating. The safety performance of the cylindrical lithium battery 14 has also been fully verified. Its internal chemical reaction is stable and can effectively prevent short circuits or other safety hazards under normal use conditions.

[0029] The transparent protective plate 11 of the present invention is made of a transparent resin. This resin offers both transparency and durability. The transparency of the transparent resin ensures a clear view of the display 13 through the protective plate 11. This transparency allows the user to easily view various information on the display 13, such as battery charge, temperature, and operating current. This clear display is crucial for users to keep abreast of battery status, enabling them to make appropriate adjustments or maintenance during use, thereby ensuring the proper functioning of the battery and the power tool. The transparent resin material not only excels in transparency but also possesses excellent impact resistance. The transparent protective plate 11 must withstand certain mechanical shocks and external pressures during use. Therefore, the high impact resistance of the transparent resin effectively protects the display 13 from damage. In actual use, the transparent protective plate 11 may be subject to drops and collisions. The impact resistance of the transparent resin material significantly enhances the durability of the protective plate, extending its service life. Furthermore, the transparent resin material exhibits excellent chemical resistance. Power tool batteries may come into contact with various chemicals and cleaning agents during operation. The transparent resin effectively resists these chemicals, maintaining the protective plate's transparency and appearance. The advantage of chemical resistance not only improves the durability of the guard plate, but also reduces the problem of reduced transparency due to chemical corrosion.

[0030] The bottom shell 1 of the present invention is provided with an anti-slip rubber strip 15 to improve the stability and safety of the battery during use. The main function of the anti-slip rubber strip 15 is to increase the friction between the bottom shell 1 and the contact surface, thereby preventing the battery from sliding or moving during use, and ensuring the stability of the battery in the power tool. The anti-slip rubber strip 15 on the bottom shell 1 is made of materials with excellent friction properties. These materials can effectively increase surface friction and reduce the risk of the battery sliding during operation. The material of the anti-slip rubber strip 15 has good elasticity and wear resistance, and can maintain its anti-slip performance during long-term use. Through the use of this material, the anti-slip rubber strip 15 can show a stable anti-slip effect in different working environments.
