[0030] Example

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 is an exploded schematic diagram of a battery module 100 provided in this embodiment. Figure 2 FIG. 1 is a circuit diagram of the battery module 100 .

[0032] The battery module 100 provided in this embodiment includes a mounting body 110, a double-gate switch 120 and a plurality of batteries 130. The mounting body 110 is provided with a positive terminal 1111 and a negative terminal 1112, and the double-gate switch 120 is arranged on the mounting body 110. The double-gate switch 120 has a first terminal 121, a second terminal 122, a third terminal 123 and a fourth terminal 124. The first terminal 121 is connected to the positive terminal 1111, and the second terminal 122 is connected to the negative terminal 1112. The plurality of batteries 130 are detachably arranged on the mounting body 110, and the third terminal 123, the plurality of batteries 130 and the fourth terminal 124 are connected in series in sequence. When the double-gate switch 120 is closed, the third terminal 123 is connected to the first terminal 121, and the fourth terminal 124 is connected to the second terminal 122.

[0033] It is understandable that the positive terminal 1111 and the negative terminal 1112 serve as the positive and negative electrodes for the battery module 100 to discharge externally. In practical applications, when the double-gate switch 120 remains disconnected, the positive terminal 1111 and the negative terminal 1112 are not electrically connected to the multiple batteries 130; when the double-gate switch 120 is closed, the positive terminal 1111 is connected in series with the multiple batteries 130 and the negative terminal 1112. In this case, the positive terminal 1111 and the negative terminal 1112 are electrically connected to the electrical equipment, and the multiple batteries 130 form a series circuit with the electrical equipment, so that the multiple batteries 130 can supply power to the electrical equipment in combination.

[0034] Since the installation body 110 can fix the relative positions of the multiple batteries 130, in actual applications, the multiple batteries 130 will not be relatively displaced, ensuring that the series circuit is stable and reliable. In addition, when it is necessary to disassemble the multiple batteries 130 in the battery module 100, in order to avoid electric shock, the operator can first switch the double-gate switch 120 from the closed state to the open state, so that the series circuit is not energized, ensuring that no electric shock occurs when the batteries 130 are disassembled.

[0035] In order to further improve the safety of the circuit, the battery module 100 provided in this embodiment further includes a fuse 140, and the third terminal 123, the fuse 140, the plurality of batteries 130 and the fourth terminal 124 are sequentially connected in series. In practical applications, the fuse 140 can melt automatically when the current in the circuit increases abnormally, thereby cutting off the circuit and avoiding accidents.

[0036] In this embodiment, the installation body 110 includes a box body 111 and a cover body 112. The positive terminal 1111, the negative terminal 1112 and the double-gate switch 120 are all arranged on the box body 111. The box body 111 has a plurality of installation grooves 1113. The plurality of batteries 130 are respectively embedded in the plurality of installation grooves 1113. The cover body 112 is detachably connected to the box body 111 and covers the plurality of installation grooves 1113.

[0037] In order to realize convenient assembly and disassembly between the cover 112 and the box 111, and thus realize rapid disassembly of the battery 130, in this embodiment, the cover 112 and the box 111 are snap-fitted. Specifically, the cover 112 is provided with an elastic snap 1121, and the box 111 is provided with a clamping portion 1114, and the elastic snap 1121 is clamped with the clamping portion 1114.

[0038] It should be noted that in other embodiments, the cover 112 and the box 111 may be connected in other ways according to actual application conditions. For example, bolts may be used, or hinges or other structures may be used to realize that the cover 112 is reversibly arranged on the box 111.

[0039] In order to improve the sealing performance and prevent external water, insects, dust and other substances from entering the installation groove 1113 during use and causing damage to the battery 130 or short circuit, in this embodiment, sealing rings 1115 are provided on the periphery of multiple installation grooves 1113 on the surface of the box body 111. When the cover body 112 is connected to the box body 111, the multiple sealing rings 1115 respectively seal the gaps formed by the cover body 112 and the box body 111 at the periphery of each installation groove 1113.

[0040] It is understandable that, when the cover 112 is opened, the sealing ring 1115 protrudes from the surface of the box 111 where the mounting groove 1113 is provided. In the process of closing the cover 112 on the box 111, the cover 112 gradually squeezes the sealing ring 1115 to deform it, until the elastic buckle 1121 on the cover 112 is clamped on the clamping part 1114 on the box 111, so that the gap around the mounting groove 1113 is blocked by the sealing ring 1115, thereby realizing reliable sealing of the mounting groove 1113.

[0041] In another embodiment, an integral sealing ring 1115 may be used to achieve unified sealing of multiple installation grooves 1113. For example, a sealing ring 1115 may be set on the surface of the box body 111 to surround all the installation grooves 1113, so that when the cover body 112 is closed on the box body 111, the cover body 112 squeezes the sealing ring 1115 to complete the unified sealing of all the installation grooves 1113.

[0042] In order to further improve the safety and convenience of the disassembly and assembly process, in this embodiment, the cover body 112 is provided with a pre-embedded circuit. When the cover body 112 covers the multiple installation slots 1113, the third terminal 123, the multiple batteries 130 and the fourth terminal 124 are connected in series to the pre-embedded circuit.

[0043] Specifically, the pre-buried circuit includes a positive cable 1122, an intermediate cable 1125, and a negative cable 1127 arranged inside the cover 112, and also includes a positive plug 1123, a negative plug 1128, a plurality of positive springs 1124, and a plurality of negative springs 1126 disposed on the cover 112 and exposed to the outside. One end of the positive cable 1122 is connected to the positive plug 1123, the other end of the positive cable 1122 is connected to a positive spring 1124, the two ends of the intermediate cable 1125 are respectively connected to a positive spring 1124 and a negative spring 1126, one end of the negative cable 1127 is connected to the negative plug 1128, and the other end of the negative cable 1127 is connected to a negative spring 1126. When the cover 112 is separated from the box 111 , the positive cable 1122 , the negative cable 1127 , and the plurality of intermediate cables 1125 are separated from each other and are not connected to each other.

[0044] In fact, the plurality of mounting slots 1113 are sequentially arranged on the box 111, that is, the plurality of storage batteries 130 are sequentially arranged on the box 111 to form an arrangement queue. When the cover 112 covers the plurality of mounting slots 1113, the positive plug 1123 at one end of the positive cable 1122 is plugged into the third terminal 123 of the double-gate switch 120, and the positive spring 1124 at the other end of the positive cable 1122 abuts against the positive pole of the first storage battery 130 in the arrangement queue.

[0045] When the cover 112 covers the multiple installation slots 1113, the multiple intermediate cables 1125 are distributed between multiple groups of two adjacent batteries 130 to complete the series connection of the multiple batteries 130. Specifically, the negative spring piece 1126 at one end of any intermediate cable 1125 abuts against the negative pole of one of the two adjacent batteries 130 in the arrangement queue, and the positive spring piece 1124 at the other end abuts against the positive pole of the remaining one of the two adjacent batteries 130 in the arrangement queue. In addition, the negative plug 1128 at one end of the negative cable 1127 is plugged into the fourth terminal 124 of the double-gate switch 120, and the negative spring piece 1126 at the other end abuts against the negative pole of the battery 130 at the end of the arrangement queue.

[0046] In this embodiment, the third terminal 123 and the fourth terminal 124 of the double-gate switch 120 are both sockets with their openings facing upward. When the cover 112 is closed on the box body 111, the positive electrode plug 1123 aligns itself and is inserted into the third terminal 123, and the negative electrode plug 1128 aligns itself and is inserted into the fourth terminal 124, and the multiple positive spring sheets 1124 respectively abut against the multiple positive poles of the multiple batteries 130, and the multiple negative spring sheets 1126 respectively abut against the multiple negative poles of the multiple batteries 130.

[0047] In addition, in this embodiment, the fuse 140 is arranged in series on the positive cable 1122, and in order to facilitate the replacement of the fuse 140, the fuse 140 is exposed on the surface of the cover 112. In the process of closing the cover 112 on the box 111, the series connection of the third terminal 123, the fuse 140, the plurality of batteries 130 and the fourth terminal 124 is automatically and synchronously completed, and the operator does not need to perform wiring operations separately. In addition, in the process of opening the cover 112, the disconnection operation of all batteries 130 is automatically and synchronously completed, so that the operator can immediately remove the battery 130 after opening the cover, eliminating the operation of removing the cable, and the operation is convenient and fast with higher safety.

[0048] In summary, the battery module 100 provided in this embodiment has the characteristics of easy assembly and disassembly and high safety in use.

[0049] In addition, this embodiment further provides an electric device, including the aforementioned storage battery module 100. Benefiting from the beneficial effects of the storage battery module 100, the electric device provided by this embodiment also has the characteristic of higher safety in use.

[0050] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
