[0026] In addition, the meaning of the term "a plurality of" should be two and more than two.

[0027] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0028] As Figs. 1 to 3As shown, a dust collector battery assembly quick disassembly structure includes two opposite clamping plates 1 and a plurality of charging battery modules 10, the clamping plate 1 is fixedly provided with a plurality of docking interfaces 2, the two ends of the charging battery module 10 are respectively connected with the docking interfaces 2 on the two clamping plates 1, the depth of the docking interface 2 is not more than one third of the length of the charging battery module 10, the outer end of the docking interface 2 is fixedly provided with a limiting structure for preventing the displacement of the charging battery module 10, and a disassembly connection assembly is further fixedly arranged between the two clamping plates 1.

[0029] Specifically, the slightly higher cost of the dust collector has a battery management module in the built-in chip board, which can display the use of each charging battery module 10, which provides a reference for replacing a charging battery module 10. In this embodiment, the two ends of the plurality of charging battery modules 10 are inserted into the docking interfaces 2 on the clamping plates 1 and the two ends of the charging battery modules 10 are limited by the limiting structure, and then the two clamping plates 1 are connected into one by using the disassembly connection assembly, which can not only ensure that all charging battery modules 10 are fixed into an integrated structure, but also can replace a charging battery module 10 individually after the disassembly connection assembly is disassembled. The depth of the docking interface 2 is not more than one third of the length of the charging battery module 10, so that at least one third of the length of the charging battery module 10 is exposed, which is beneficial to the heat dissipation of the battery and prolongs the service life of the battery. The two clamping plates 1 are arranged to limit the position of the two ends of the charging battery module 10, and all the charging battery modules 10 are bound into one by the disassembly connection assembly, which is convenient for replacing the charging battery module 10 and beneficial to the heat dissipation of the battery.

[0030] The limiting structure includes a limiting plate 3 arranged at the outer end of the docking interface 2, which limits the outer edge of the end of the charging battery module 10. Specifically, the conventional charging battery module is bound into one by a binding belt, and there are lines inside the binding belt to connect the small charging batteries in series, so that the conventional charging battery module has only one positive terminal and one negative terminal. However, in this embodiment, since the single battery module needs to be disassembled and replaced, it is not suitable to connect the charging battery modules 10 in series by a cable, so an external circuit board needs to be designed, which has a plurality of power terminals. After the entire charging battery module is connected with the external circuit board, the positive and negative poles of each charging battery module 10 are in contact with the power terminals to realize the series connection of all charging battery modules 10. Therefore, the end of the docking interface 2 not only has the function of limiting the charging battery module 10, but also leaves space for the contact of the terminals with the positive and negative poles of the charging battery, so the structure of the limiting plate 3 only limits the outer edge of the end of the charging battery module 10, and the middle is left empty to facilitate the contact with the terminals.

[0031] The dismounting connecting assembly comprises several pairs of connecting assemblies, each of the connecting assemblies comprises two elastic tabs 4, one end of each of the two elastic tabs 4 is fixedly arranged on the two clamping plates respectively, and the two elastic tabs 4 are fixedly connected through a clamping structure at the end close to each other. The clamping structure comprises a clamping protrusion 5 and a clamping hole 6, and the clamping protrusion 5 and the clamping hole 6 are fixedly arranged on the two elastic tabs 4 respectively. Specifically, the two elastic tabs 4 are pulled close to each other, and then the clamping protrusion 5 is pressed into the clamping hole 6 to realize the connection of the two, at this time, the two elastic tabs 4 are in a taut state, the clamping plates 1 on both sides can be pulled close to the middle, and then all the rechargeable battery modules 10 can be aggregated into a whole without loosening; when dismounting, the clamping protrusion 5 only needs to be pressed out of the clamping hole 6, and the operation is simple.

[0032] The material of the elastic tab 4 is silica gel, and the clamping hole 6 and the clamping protrusion 5 are integrally formed with the elastic tab 4. Specifically, silica gel has good deformation ability and elastic force, and can be slightly deformed to tighten the two clamping plates 1.

[0033] The clamping plate 1 comprises a plurality of sleeves 7, the outer walls of all the sleeves 7 are fixedly connected in sequence, the docking port 2 is the inner cavity of the sleeve 7, and the material of the sleeve 7 is heat-conducting plastic. Specifically, the connecting mode of the plurality of sleeves 7 can make the part of the rechargeable battery module 10 inserted into the docking port 2 thinner in the outer wall of the clamping plate 1 that needs to be penetrated during heat dissipation, and is more conducive to the heat dissipation of the battery.

[0034] The bottom of the sleeve 7 has a flat end face 8, and the dismounting connecting assembly is fixedly arranged on the flat end face 8. Specifically, the flat end face 8 facilitates the installation of the elastic tab 4 and makes the entire battery module stable when placed inside the dust collector.

[0035] The clamping plate 1 further fixedly has a charging interface 9, and the charging interface 9 is electrically connected with the rechargeable battery module 10. Specifically, the rechargeable battery module 10 is charged through the charging interface 9.

[0036] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
