Detailed Description

The invention is described in detail below with reference to the figures and the embodiments.

The battery pack 100 shown in fig. 1 includes: a battery cell (not shown), a housing 10, and an indicator assembly 20. The casing 10 is used for accommodating the battery cells, and the indication assembly 20 is used for indicating the state of the battery pack 100.

Specifically, the indicating assembly 20 is electrically connected to the battery cell directly or indirectly; firstly, the battery cell provides electric energy support for the indicating component 20; secondly, the indication assembly 20 can detect various electrical parameters of the battery cell through corresponding electrical connection lines so as to realize the indication function of data such as electric quantity, remaining service time, remaining charging time and the like.

The indication assembly 20 includes a percentage indication portion 201, and the percentage indication portion 201 can indicate the remaining capacity of the battery pack 100, that is, the remaining capacity of the battery pack 100 stored in the battery cells, in percentage.

As a specific solution, the indicating component 20 indicates the percentage of remaining charge to be accurate to 5% minimum. It should be noted that, as shown in fig. 7, the indication component 20 indicates the percentage of the remaining power to be accurate to 5% at least, which means that the indication component 20 always indicates 5% when the remaining power is indicated by percentage, but the indication component 20 can indicate the remaining power of the battery pack 100 with an accuracy of 5% when the remaining power of the battery pack 100 is within a certain percentage interval.

For the user, if the battery pack 100 is used, the remaining capacity of the battery pack 100 may be concerned when the capacity of the battery pack 100 is exhausted, and if the battery pack 100 is charged, the capacity of the battery pack 100 may be concerned when the battery pack 100 is fully charged. In contrast, users tend to be more concerned about the exact amount of power when the battery pack 100 is running out of power, as this relates to whether the user is doing brief work with the battery pack 100 or first recharging the battery pack 100 and then working or replacing other battery packs 100. As shown in fig. 7, the indication interface provided by the indication component 20 is divided into three large indication intervals of 100%, 75% and 50%, which respectively indicate that the percentages of the remaining capacity of the battery pack 100 are in the interval of 75% to 100%, 50% to 75% and 25% to 50% when the corresponding interval is lighted; in order to accurately determine the remaining capacity below 25%, the remaining percentage interval is divided into five intervals, which respectively indicate the remaining five equally divided intervals, that is, when the remaining capacity of the battery pack 100 is below 25%, the user can know the exact remaining capacity of the battery pack 100 through the observation of the indication interface of the indication assembly 20, so that he/she can decide whether to use the battery pack 100 or charge the battery pack 100. Of course other indications may be deemed to require a precise indication interval and a lesser degree of accuracy, such as 1%, may be chosen.

As shown in fig. 1 to 7, the percentage indicating part 201 includes a plurality of indicator lamps 21 and an indicator 22. Wherein the indicator light 21 is used for generating an indicating light source, and the indicator piece 22 is used for covering the indicator light 21 and forming a corresponding interval for indicating. Specifically, the indicator 22 is provided with a plurality of indicator panes 221, each indicator pane 221 is used to indicate a certain percentage range, the indicator lamps 21 are correspondingly arranged at positions corresponding to different indicator panes 221, and when the corresponding indicator lamp 21 illuminates the corresponding indicator pane 221, the remaining capacity of the battery pack 100 is indicated to be in the percentage range corresponding to the indicator pane 221. Therefore, the remaining capacity of the battery pack 100 can be displayed on the indication interface formed by the indication assembly 20 by controlling whether the corresponding indication lamp 21 is lighted or not.

As shown in fig. 3 and 5, the indicator 22 is a ring-shaped member which is broken at certain portions of the circumference so that a circumference forms several separate regions as the indication panes 221 corresponding to the respective percentage ranges.

As shown in fig. 3, the indicating assembly 20 further includes a circuit board 23 and a controller 24, the circuit board 23 is at least used for connecting the indicating lamp 21 and connecting the battery cells so as to supply power to the indicating lamp 21 connected therewith. The controller 24 is used to control whether the indication component 20 is in a state of indicating the remaining power of the battery pack 100, and since the indication component 20 needs to consume power, the controller 24 can enable the indication component 20 to display the remaining power when the display is needed, and reduce power consumption when the display is not needed.

As shown in fig. 3, the indication assembly 20 further includes an operation portion 202 for operation by a user to control the controller 24. Specifically, the operation unit 202 includes the button 25. The button 25 is used for pressing by the user, and the user can switch the control state of the controller 24 when operating the button 25. As an embodiment, the button 25 can be directly or indirectly movably connected to the housing 10, so that the user can trigger the switch of the state of the controller 24 by changing the position of the button 25, for example, pressing the button 25 activates the indicator light 21 to enable the indicator assembly 20 to indicate the remaining power of the battery pack 100, and then pressing the button 25 turns off the indicator light 21 to disable the indicator assembly 20 to indicate the remaining power of the battery pack 100, although the button 25 can also control the indicator light 21 by using different positions to trigger different control states.

As shown in fig. 5, the button 25 is a transparent cover that can slide relative to the indicator 22 and covers the outside of the indicator 22. The user can thus observe the illumination of the indicator light 21 inside the button 25 through the button 25. The button 25 is centrally provided with a post structure 251 which contacts the controller 24.

As shown in fig. 3 and 4, the indicating assembly 20 may alternatively further include: an enclosure 26, a biasing member 27 and a bracket 28, wherein the enclosure 26 guides the button 25 to limit the extreme position of the button 25, and the enclosure 26 is formed with an exposing hole 261 partially exposing the button 25 so that a user can directly operate the button 25. The biasing member 27 serves to bias the button 25 to move in the reset direction. The biasing member 27 includes resilient legs 271 and a contact ring 272, the resilient legs 271 being disposed about the contact ring 272, the contact ring 272 being a ring structure that is adapted to contact the push button 25 to impart a biasing force to the push button 25.

The bracket 28 is used to position the indicator 22 while supporting it while being mounted over the circuit board 23. The support 28 comprises support legs 281 and positioning projections 282, the support legs 281 extending all around to connect with the periphery of the circuit board 23, the positioning projections 282 projecting in the direction of the indicator 22 and being inserted in the breaks between the different indicator panes 221 after assembly, thus serving to position and separate the light.

Specifically, when assembled, the indicator 22 is mounted in the contact ring 272 and engaged with the positioning protrusions 282 of the bracket 28, then the button 25 covers the indicator 22 and a portion of the contact ring 272, and then is packaged as a whole by the packaging case 26 and mounted inside the housing 10 of the battery pack 100 as shown in fig. 6, and the housing 10 of the battery pack 100 is formed with corresponding through holes 11 to expose the indication interface of the indication assembly 20 to the housing 10 for the user to observe.

As shown in fig. 2 and 7, the indication assembly 20 may further include a time indication part 203, and the time indication part 203 indicates time, which may be used for remaining usage time of the battery pack 100 when discharged or time required for full charge of the battery pack 100 when charged. The control circuit inside the battery pack 100 can adjust and display the data of the remaining service time in real time according to the change of the discharge current during discharge, and can also adjust and display the time required for full charge according to the change of the charge point current and the voltage during charge.

Specifically, the time indicator 203 includes an indicator screen (not shown), which may be an LED screen, an LCD screen, or the like. Preferably, in order to save space, on the basis of the above solution, the indicator screen is arranged in the center of the annular indicator piece 22.
