Embodiment 1

[0051] The embodiment of the present application discloses a lithium battery module for garden tools.

[0052] refer to figure 1 , figure 2 , a lithium battery module for garden tools, comprising a shell assembly 1 and a lithium battery assembly 2 installed inside the shell assembly 1 for supplying power to the garden tools.

[0053] refer to figure 2 , the lithium battery assembly 2 includes several lithium batteries 21 and two battery cell holders 22 for fixing the lithium batteries 21. The number of lithium batteries 21 in the lithium battery assembly 2 can be three, four, or five. It needs to be determined according to the rated voltage of the garden tool used with the lithium battery module. In this embodiment, the number of lithium batteries 21 is set to four, and the four lithium batteries 21 have a working voltage suitable for garden tools after being connected in series and parallel.

[0054] refer to figure 2 , the four lithium batteries 21 in this embodiment...

Embodiment 2

[0073] The embodiment of the present application discloses a lithium battery module for garden tools.

[0074] refer to Figure 8 , Figure 9 , the difference between the lithium battery module for garden tools disclosed in the embodiment of the present application and the embodiment 1 is:

[0075] In this embodiment, two positioning rods 1324 are rotatably connected to the side of each partition plate 1323 facing the adjacent partition plate 1323 , that is, there are four positioning rods 1324 in one installation chamber 3 ; each positioning rod 1324 is away from the partition plate 1323 One end of each locating rod 1324 is provided with an integrally formed ball head; an elastic member 1325 is provided between each positioning rod 1324 and the connected partition plate 1323, and the two opposite positioning rods 1324 are normally mutually mutually under the action of the elastic force of the elastic member 1325. approach so that the ball heads of the two positioning rods 1...

Abstract

The invention relates to a lithium battery module for a gardening tool. The lithium battery module comprises a shell assembly and a lithium battery assembly; the shell assembly comprises a lower shell and an upper cover which are detachably connected, and the lithium battery assembly is mounted in the lower shell; a dismounting structure is arranged on the outer side of the shell assembly and comprises a clamping hook arranged on the upper cover and a plurality of sockets formed in the lower shell, and the clamping hook is used for being connected with a gardening tool used in cooperation with the lithium battery module; a conductive clamping spring is installed in the socket, two elastic clamping parts are arranged on the side, facing the socket, of the conductive clamping spring, and the two clamping parts abut against each other in the normal state and are used for clamping a power connector of a gardening tool used in cooperation with the lithium battery module. According to the lithium battery module for the gardening tool, damaged parts can be conveniently replaced in a single-section mode, and the service life of the whole lithium battery module can be prolonged.

Description

technical field [0001] The present application relates to the technical field of battery packs, and in particular, to a lithium battery module for garden tools. Background technique [0002] Lithium battery refers to the battery containing lithium in the electrochemical system, including metal lithium, lithium alloy, lithium ion and lithium polymer; lithium battery converts the chemical energy inside the battery into electrical energy through chemical reaction, so as to supply power to external equipment, so that External devices are functioning normally. The voltage and capacity of a single lithium battery are small. In order to meet the requirements of voltage and capacity, lithium batteries usually need to be combined into a battery pack for use. [0003] At present, the lithium battery module in the prior art generally includes a plurality of lithium batteries used in combination, a PCB protection board electrically connected to the lithium battery, and a shell for inst...
