In a possible embodiment, the fixing base 5 and the housing 2 can be connected together by a snap fit, so that the fixing base 5 can be directly detached from the housing 2 without any other tools.

The motor 2 of intelligence lawn mower can be installed in fixing base 5, and motor 2 is used for driving the cutting module and rotates. The motor 2 and the fixing base 5 can be fixedly connected, for example, the motor 2 is screwed on the fixing base 5 through a screw to connect the two into a whole.

The shaft of the motor 2 is directed substantially downward, so that, as shown in fig. 4, a cutting module may be directly mounted on the bottom of the housing 1, and the cutting module may be rotated substantially in a horizontal direction, so that the cutting module can cut grass under the housing 1 when the intelligent lawn mower is driven.

In a feasible embodiment, the fixing seat 5 is located at the upper end of the machine base 1, and only the shaft of the motor 2 faces downwards, so that the cutting module is ensured to be installed on the shaft of the motor 2 from the bottom of the machine base 1. Of course, the motor 2 may also be located in the middle of the base 1, for example, in a notch of the base 1 body, the shaft of the motor 2 is downward from the base 1, and the cutting module is mounted on the shaft of the motor 2 from the bottom of the base 1.

In several above-mentioned embodiments, fixing base 5 can be dismantled with frame 1 and be connected, so, can be convenient dismantle fixing base 5, motor 2 and cutting module from intelligent lawn mower together. Fig. 5 is a schematic view of a grass trimmer adopting a cutting module, and as shown in fig. 5, the fixing seat 5 of the intelligent grass trimmer in the present application has the same structure as the fixing seat 5 for fixing the motor in the grass trimmer and the pruner, so that the fixing seat 5 in the present application can be directly installed on the grass trimmer and the pruner. Fixing base 5 of intelligence lawn mower can directly be dismantled from frame 1, direct mount is to the machine of beating grass, the frame on the pruner directly uses, thereby make the user need not to have simultaneously with the machine of beating grass, pruner complex fixing base 5, including a motor, an end cap, a controller, and a cover plate, cutter disc mechanism and with intelligent lawn mower complex fixing base 5, including a motor 2, cutter disc mechanism 32, so can effectively reduce the cost that the user bought, and the multiple different fixing base 5 in later stage, including a motor, the shared storage space of cutter disc mechanism, the fixing base 5 of intelligence lawn mower in this application, motor and cutter disc mechanism can satisfy intelligent lawn mower simultaneously, the garden instrument that beating grass machine and pruner etc. have fixing base 5 uses.

In a possible embodiment, the motor 2 may also be directly mounted on the frame 1, and the fixing base 5 may not be provided between the motor 2 and the frame 1.

As shown in fig. 1 to 3, the cutting module may be installed at the bottom of the housing 1. The cutting module may include: a connecting sleeve 31 sleeved on the shaft of the motor 2; a cutter disc mechanism 32 is mounted on the coupling sleeve 31. The connecting sleeve 31 may have an opening 311 through which the shaft of the motor 2 can be inserted, and the connecting sleeve 31 and the shaft of the motor 2 may be in interference fit through the opening 311, so as to ensure that the motor 2 can drive the connecting sleeve 31 to rotate. Of course, the cross section of the opening 311 of the connecting sleeve 31 may have a non-circular shape, and the shaft of the motor 2 may have a shape matching the cross section of the opening 311 of the connecting sleeve 31. Through the mode, the motor 2 can drive the connecting sleeve 31 to rotate.

The cutter disc mechanism 32 in the present application can be directly installed on the grass trimmer, the connecting sleeve 31 of the intelligent grass trimmer in the present application has the same structure as the connecting sleeve 31 of the grass trimmer, the connection mode of the cutter disc mechanism 32 is the same as that of the connecting sleeve in the grass trimmer and the cutter disc mechanism of the grass trimmer, therefore, the cutter disc mechanism 32 of the intelligent mower is detachably connected with the connecting sleeve 31, the cutter disc mechanism 32 can be directly detached from the connecting sleeve 31 and directly mounted on the connecting sleeve of the mower for direct use, therefore, the user does not need to simultaneously have a connecting sleeve matched with the grass trimmer and a connecting sleeve matched with the intelligent grass trimmer, thus effectively reducing the purchase cost of the user, and the shared storage space of the cutting module of the multiple different grade type in later stage, the cutting module of intelligent lawn mower in this application can satisfy intelligent lawn mower and the use of machine of beating grass simultaneously.

In order to allow the cutter disc mechanism 32 to be removably attached to the attachment sleeve 31, in one possible embodiment, as shown in fig. 2 and 3, the attachment sleeve 31 may be provided with at least two through holes 312; cutter disc mechanism 32 includes: the cutter disc 321 is arranged on one side of the connecting sleeve 31 with the opening 311, and at least two through holes 3211 are formed in the cutter disc 321; and the fixing piece 322 penetrates through the through hole 3211 and is inserted into the through hole 312, so that the cutter disc 321 and the connecting sleeve 31 synchronously rotate. The cutter disc 321 is arranged on the connecting sleeve 31 through the fixing piece 322, meanwhile, the connecting sleeve 31 can drive the cutter disc 321 to rotate, a cutting piece 3213 is arranged at the edge of the cutter disc 321, and when the cutter disc 321 rotates, the cutting piece 3213 cuts grass.
