[0036] Embodiment 1

[0037] An embodiment of the present application discloses a battery module, including a shell 100; a battery assembly 200, installed in the shell 100; a circuit board assembly 300, installed in the shell 100 and electrically connected to the battery assembly 200; a marquee group 400, electrically connected to the circuit board assembly 300 and the battery assembly 200; wherein the marquee group 400 includes a plurality of lamp beads 410; the number of lamp beads 410 that light up corresponds to the remaining power of the battery assembly 200; wherein a window 110 is provided on the body 100 corresponding to the marquee group 400.

[0038] As shown in the figure, in the present embodiment, the battery module includes a shell 100, in which a battery assembly 200, a circuit board assembly 300 and a marquee group 400 are installed; the marquee group 400 is electrically connected to the battery assembly 200 and the circuit board assembly 300 respectively; wherein the marquee group 400 includes a plurality of lamp beads 410, the number of lamp beads 410 that light up corresponds to the remaining power of the battery assembly 200, and a window 110 is provided on the shell 100 corresponding to the marquee group 400 so that the light of each lamp bead 410 can pass through the shell 100; when it is necessary to display the power status, the circuit board assembly 300 controls all the lamp beads 410 in the marquee group 400 to light up in sequence and orderly, forming a specific light effect like "chasing each other" (flowing water), which is more beautiful. When the final frame is frozen, only the number of lamp beads 410 corresponding to the remaining power of the battery is lit, so that the user can intuitively observe the power status to meet the diversified needs of different users for the battery module.

[0039] It is understandable that the marquee group 400 itself should have multiple lamp beads 410. For example, an ordinary rechargeable battery only has 4 power display lights, and one lamp bead represents one grid of power, and one grid of power is 25%. The remaining power displayed in this way is very inaccurate. If the same column of the embodiment of the present application has 10 lamp beads, then one lamp bead 410 only represents 10%, and the power display is more accurate. It is understandable that the more lamp beads there are, the smaller the power represented by one lamp bead 410, and the corresponding power display is more accurate. For example, the number of lamp beads 410 is 15, 20, and so on, which is convenient for users to use the embodiment of the present application in a planned way and reduce the occurrence of situations where the embodiment of the present application has no power when it is needed.

[0040] In an optional implementation, the circuit board assembly 300 includes a marquee control chip and a charge and discharge control chip connected to the battery assembly 200 , and the marquee control chip is connected to the marquee group 400 .

[0041] In this embodiment, all the lamp beads 410 are controlled by the marquee control chip to light up in sequence according to a specific pattern; the specific pattern may be, for example: lighting up once or several times in sequence from the first lamp bead 410 to the last lamp bead 410 of the marquee group 400; lighting up once or several times from both sides of a group of lamp beads 410 to the middle; lighting up once or several times from the middle to both sides of a group of lamp beads 410; or lighting up multiple lamp beads 410 in sequence, with the lamp beads 410 that have been lit gradually dimming, etc., in order to show a "flowing water" (marquee) visual effect; the charge and discharge control chip is used to control the charge and discharge process of the battery assembly 200.

[0042] In an optional embodiment, the marquee group 400 has a power display state. In the power display state, all the lamp beads 410 light up at least once in turn, and then only the lamp beads 410 of the number corresponding to the remaining power will be lit up eventually; by first moving all the lamp beads 410 in a marquee manner when displaying the power, an aesthetic effect is achieved; and then only the lamp beads 410 of the number corresponding to the remaining power will be lit up eventually, so that the user can intuitively understand the remaining power; optionally, all the lamp beads 410 light up in a cycle once, twice or three times, and too many cycles are not conducive to timely display of the remaining power.

[0043] In an optional embodiment, the battery assembly 200 includes a bracket 210, and one side of the bracket 210 is connected to a plurality of battery fixing seats 220 adjacent to each other; the other side of the bracket 210 is connected to a circuit board assembly 300; the battery fixing seat 220 and the circuit board assembly 300 are fixed together by the bracket 210, so that the space they occupy in the shell 100 is smaller, making the overall structure of the embodiment of the present application compact, small in size, and easy to carry and use; optionally, the battery assembly 200 also includes a lithium battery, and the battery fixing seat 220 is fixed with a lithium battery to serve as a power reserve.

[0044] In an optional embodiment, the shell 100 includes an upper shell 120 and a lower shell 130, and the upper shell 120 and the lower shell 130 are detachably connected; a button 121 is provided on the upper shell 120, and the button 121 is connected to the circuit board assembly 300 and / or the marquee group 400, in order to control the opening and closing of the marquee group 400.

[0045] like Figure 1-5 As shown, in this embodiment, the upper shell 120 and the lower shell 130 are detachably connected, so as to facilitate the disassembly, assembly and maintenance of the components such as the marquee group 400, the circuit board assembly 300, the battery assembly 200, etc. in the shell 100; a button 121 is provided on the upper shell 120, and the button 121 is connected to the circuit board assembly 300. After the button 121 is pressed, the circuit board assembly 300 controls the operation of the marquee group 400, and finally lights up the number of lamp beads 410 corresponding to the remaining power after executing the "marquee" action.

[0046] In an optional embodiment, a plurality of lamp beads 410 are arranged in at least one line or ring; in order to perform the "horse racing" action, the lamp beads 410 are preferably arranged regularly, and both linear and ring arrangements can satisfy the execution of the action.

[0047] In an optional embodiment, the lamp beads 410 are symmetrically arranged in two rows on both sides of the board surface of the circuit board assembly 300; the shape of the window 110 is adapted to the arrangement shape of the lamp beads 410; by symmetrically arranging two rows of lamp beads 410 on both sides of the circuit board on the circuit board assembly 300, when the button 121 is pressed, the two rows of lamp beads 410 light up in sequence at the same time, and finally only the number of lamp beads 410 corresponding to the remaining power is lit, and the light emitted by the lamp beads 410 shines through the window 110.

[0048] In an optional embodiment, the window 110 includes a long groove opened on the housing 100 and a light shield installed in the long groove; this structural design facilitates the assembly work of the embodiment of the present application.

[0049] In an optional embodiment, the length of the connection of the lamp beads 410 in a single row accounts for at least three quarters of the length of the shell 100 and / or the number of the lamp beads 410 in a single row is at least 8; the length of the connection of the lamp beads 410 in a single row accounts for at least three quarters of the length of the shell 100, so that the arrangement of the lamp beads 410 is basically connected along the direction of the shell 100 to present a better visual effect; the number of the lamp beads 410 in a single row is at least 8, and it can be understood that the number of the lamp beads 410 can be 8, 9, 10, 11...20 or more; and more lamp beads 410 can make the remaining The display of the remaining power is more accurate. For example, an ordinary rechargeable battery only has 4 power display lights, and one lamp bead represents one grid of power, and one grid of power is 25%. The remaining power displayed in this way is very inaccurate. If the same column of the embodiment of the present application has 10 lamp beads, then one lamp bead 410 only represents 10%, and the power display is more accurate, which is convenient for users to use in a planned manner. At the same time, in order to present a better "horse racing effect", the number of lamp beads 410 cannot be set too small and / or the connection line formed by all the lamp beads 410 cannot be short, otherwise it is difficult to reflect its aesthetics.
