Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to an energy storage power supply module and a lawn mower equipped with the energy storage power supply module. Background Art

[0002] A lawn mower is a mechanical tool used to mow lawns, vegetation, etc. It consists of a cutter disc, an engine, running wheels, a traveling mechanism, a blade, an armrest, and a control part.

[0003] The cutter disc is mounted on the travel wheel, an engine is mounted on the cutter disc, and a blade is mounted on the output shaft of the engine. The blade greatly increases the speed by utilizing the high-speed rotation of the engine, thus saving the working time of the weeding workers and reducing a large amount of human resources.

[0004] In the existing lawn mower, since there are electronic control components, batteries are also connected to the lawn mower in order to provide stable power supply to the electronic control components. However, the existing battery usually provides a single power supply, and when there are many electronic control components, multiple independent batteries need to be added, resulting in a non-compact structure of the lawn mower. Summary of the invention

[0005] The purpose of the utility model is to provide an energy storage power supply module with compact structure and high stability in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A power storage module, a lawn mower includes a frame, characterized in that the power storage module is connected to the frame, and includes a base, a battery pack, a heat dissipation cover and an interface assembly, wherein the lower portion of the base is fixedly connected to the frame, the lower portion of the battery pack is connected to the base, the heat dissipation cover is fixedly connected to the upper portion of the battery pack, the interface assembly is transversely arranged and fixedly connected to the side of the battery pack, and a buffer structure is provided between the base and the battery pack.

[0008] The energy storage power module creatively fixes the battery pack to the upper part of the base.

[0009] Since the lawn mower will generate relatively large vibrations during use, the buffer structure can effectively avoid rigid contact between the battery and the frame and appropriately absorb the vibrations at the battery.

[0010] The heat dissipation cover can dissipate heat to the battery appropriately.

[0011] Since the base is relatively large in size, the battery pack is a component that integrates a number of batteries together, and the battery pack can be stably positioned by the base.

[0012] At the same time, the interface component has multiple external interfaces, and the above multiple interfaces are connected to the independent batteries on the battery pack accordingly, ensuring that the entire energy storage power module can supply power to the corresponding electronic control components in the lawn mower in an orderly manner.

[0013] In the above-mentioned energy storage power module, the buffer structure includes a flexible gasket and a connecting portion protruding in a grid shape at the bottom of the base, and a positioning portion is formed at each grid notch of the above-mentioned connecting portion. The above-mentioned gasket and the positioning portion are arranged one by one, and the lower part of the gasket is fixedly connected to a positioning portion, and the upper part of the gasket rests on the lower part of the battery pack.

[0014] After the gasket 1 is connected to the connecting part 1, the gasket 1 can be stably connected to the bottom of the base. Since the gasket 1 is located between the base and the bottom of the battery pack, the bottom of the battery pack can be stably supported by the flexible gasket 1 and play an appropriate buffering role.

[0015] In the above energy storage power module, the first positioning portion and the base are an integrated structure.

[0016] This can appropriately improve the structural compactness of the base.

[0017] In the above-mentioned energy storage power module, the buffer structure also includes a flexible gasket 2 and a baffle protruding from the inner side of the base, and a positioning portion 2 is formed between adjacent baffles. The above-mentioned gasket 2 is arranged in a one-to-one correspondence with the positioning portion 2, the inner side of the gasket 2 is connected to the positioning portion 2, and the outer side of the gasket 2 is against the side of the battery pack.

[0018] After the gasket 2 is connected to the positioning portion 2, the gasket 2 can be stably located between the base and the side of the battery pack, thereby preventing the side of the battery pack from rigidly contacting the base.

[0019] In the above energy storage power supply module, the second positioning portion and the base are an integrated structure.

[0020] The base with an integrated structure can appropriately improve its structural compactness.

[0021] In the above energy storage power module, the heat dissipation cover is fixedly connected to the upper part of the battery pack by fasteners.

[0022] In the above energy storage power module, the interface assembly includes a long connecting plate having a plurality of through sockets along its length, and the side of the battery pack has a DC interface corresponding to the sockets one by one.

[0023] The DC interface on the battery pack is arranged in one-to-one correspondence with the socket on the connecting board. Such a structure can stably insert the corresponding plug into the corresponding DC interface, while preventing the plug from touching the battery pack.

[0024] The energy storage power module further comprises a connecting rod, the upper end of the connecting rod is fixedly connected to the heat dissipation cover, the lower end of the connecting rod is fixedly connected to the base, and the middle part of the connecting rod is passed through the connecting plate.

[0025] The connecting rod plays the role of fixing and connecting the heat dissipation cover, the connecting plate and the base.

[0026] In the above energy storage power module, an upper locking nut and a lower locking nut are threadedly connected on the connecting rod, and the above connecting plate is tightly pressed between the upper locking nut and the lower locking nut.

[0027] After the positions of the upper locking nut and the lower locking nut are adjusted, the position of the connecting plate can be changed to adapt to different battery packs.

[0028] In the above energy storage power module, the above connecting rod, the upper locking nut and the lower locking nut form a positioning unit, the number of the positioning units is two, and the two positioning units are respectively located at both ends of the connecting plate.

[0029] The setting of two positioning units can effectively improve the connection stability of the entire module.

[0030] The utility model also provides a lawn mower, which comprises the energy storage power supply module.

[0031] Compared with the prior art, the energy storage power module can effectively avoid rigid contact between the battery pack and the frame due to the base, cover plate and interface assembly being stably connected to the battery pack, and the buffer structure, thereby effectively improving stability.

[0032] At the same time, the height position of the interface component on the battery pack can be adjusted according to actual conditions, its applicability is relatively high, the overall structure is relatively compact, and it has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
