Abstract
Description
Technical Field
[0001] This utility model relates to a battery pack, specifically a battery pack power display linkage structure. Background Technology
[0002] A battery pack used in power tools is mounted on the base of the tool. The battery pack has a retractable button with a latch at the end that engages with the base. This button is pressed to install or remove the battery pack. The battery pack usually also has a power level indicator button, which is pressed when installing or removing the battery pack to check the remaining power level.
[0003] In addition to basic disassembly and assembly functions, battery packs generally feature a power display function to help users understand the remaining battery power in real time, thus allowing for reasonable usage time planning and preventing tool downtime due to insufficient power during operation. The power display function is usually triggered by a separate power indicator button; pressing this button illuminates the power indicator light on the battery pack, showing the current power status. However, this design also has some inconveniences: each time the battery pack is disassembled or assembled, the user needs to press both the disassembly / assembly button and the power display button to check the power level, which undoubtedly increases the number of steps and reduces efficiency.
[0004] Furthermore, the reliability and durability of the power indicator button, as an independent component, are also important considerations. If the power indicator button malfunctions or is damaged, the user will be unable to activate the power display function, thus failing to accurately understand the battery pack's power status. This will inconvenience the normal use of power tools and may even lead to work interruption due to depletion of power. Therefore, how to ensure convenient battery pack installation and removal while simultaneously achieving automated power display and dual protection has become a pressing issue in the current battery pack design field. Utility Model Content
[0005] In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide a battery pack power display linkage structure.
[0006] The technical solution of this utility model is: a battery pack power display linkage structure, including a shell, a first tactile switch and a power display button for pressing the first tactile switch are installed at the lower rear end of the shell, a button is installed at the upper rear end of the shell, a receiving plate is installed inside the shell, a first spring extending vertically is installed between the button and the receiving plate, a control board is installed inside the shell, the control board is provided with multiple power display lights, a pressing component is installed at the front end of the button, the pressing component includes a fixing sleeve, a second spring and a pressing head, the fixing sleeve is fixed to the bottom of the front end of the button, the pressing head extends into the fixing sleeve and slides vertically with the fixing sleeve, the second spring extends vertically and is locked between the bottom of the front end of the button and the pressing head, a second tactile switch is installed at the top rear end of the control board, and the pressing head is located directly above the second tactile switch.
[0007] Furthermore, the fixed sleeve has a through hole, and the pressure head extends into the through hole and slides up and down with the through hole.
[0008] Furthermore, the lower end of the through hole has a stop, and the upper end of the pressure head has an outwardly protruding ring. The stop is used to block the protruding ring.
[0009] Furthermore, the pressure head has an upward-facing groove, into which a second spring extends.
[0010] Furthermore, multiple power indicator lights are provided on both the front left and right sides of the control board, and a lampshade is provided on both the front left and right sides of the outer casing.
[0011] Furthermore, both the first and second tactile switches are used to control the power indicator light to illuminate.
[0012] The beneficial effects of the battery pack power display linkage structure provided by this utility model are as follows: In addition to illuminating the power display light by pressing the power display button, the button is also pressed when the battery pack is being disassembled or assembled with a power tool. The button presses down the second spring, which in turn presses down the pressure head, causing the pressure head to move downward and press the second tactile switch, which also illuminates the power display light. Therefore, even without pressing the power display button, the power display light can be illuminated when disassembling or assembling the battery pack, thus achieving automated power display and dual protection.

Detailed Implementation
[0018] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:
[0019] like Figure 1 — Figure 4 As shown, a battery pack power display linkage structure includes a housing 1. A first tactile switch 2 and a power display button 3 for pressing the first tactile switch 2 are installed at the lower rear end of the housing 1. A button 4 is installed at the upper rear end of the housing 1. A receiving plate 5 is installed inside the housing 1. A vertically extending first spring 6 is installed between the button 4 and the receiving plate 5. A control board 7 is installed inside the housing 1, and the control board 7 has multiple power display lights 8. A pressing assembly is installed at the front end of the button 4. The pressing assembly includes a fixing sleeve 9, a second spring 10, and a pressing head 11. The fixing sleeve 9 is fixed to the bottom front end of the button 4. The pressing head 11 extends into the fixing sleeve 9 and slides vertically with the fixing sleeve 9. The second spring 10 extends vertically and is engaged between the bottom front end of the button 4 and the pressing head 11. A second tactile switch 12 is installed at the top rear end of the control board 7, and the pressing head 11 is located directly above the second tactile switch 12. The fixing sleeve 9 is fixed to the bottom front end of the button 4 with screws. The top front end of the button 4 has a buckle 41 for connecting a power tool.
[0020] like Figure 2 As shown, in order to facilitate the movement of the pressure head 11, the fixed sleeve 9 has a through hole 91, and the pressure head 11 extends into the through hole 91 and slides up and down with the through hole 91.
[0021] like Figure 3 As shown, in order to prevent the pressure head 11 from falling off, there is a baffle 92 at the lower end of the through hole 91, and the upper end of the pressure head 11 has an outwardly protruding ring 111. The baffle 92 is used to block the protruding ring 111.
[0022] like Figure 2 As shown, in order to securely mount the second spring 10, the pressure head 11 has an upward-facing groove 112 into which the second spring 10 extends.
[0023] like Figure 4As shown, the control board 7 has multiple power indicator lights 8 on both the front left and right sides, and the housing 1 has a lampshade 13 on both the front left and right sides. The first tactile switch 2 and the second tactile switch 12 are both used to control the power indicator lights 8 to light up.
[0024] The battery pack power display linkage structure provided by this utility model, in addition to illuminating the power display light 8 by pressing the power display button 3, also illuminates the power display light 8 when the battery pack is disassembled or assembled with a power tool by pressing button 4. Button 4 will press down the second spring 10, and the second spring 10 will press down the pressure head 11, causing the pressure head 11 to move downward and press the second tactile switch 12. Therefore, even without pressing the power display button 3, the power display light 8 can be illuminated when disassembling or assembling the battery pack, realizing the automation of power display and dual protection.
[0025] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
