Description

Center motor structure

The present invention relates to a motor structure, and in particular to a mid-mounted motor structure.

The traditional mid-mounted motor mainly includes a motor housing, a motor contained inside the motor housing, and multiple clutch gear sets. The motor drives multiple clutch gear sets to form a variable speed ratchet, which increases the output torque of the mid-mounted motor.

However, if the yield test fails after the above-mentioned mid-mounted motor is assembled, the motor or clutch gear set needs to be replaced, but the motor and clutch gear set cannot be tested separately, which often results in the need for component replacement several times before the mid-mounted motor can pass the yield test.

In view of this, the inventor has conducted intensive research on the above-mentioned existing technologies and applied theories to try his best to solve the above-mentioned problems, which has become the development goal of the inventor.

The present invention provides a central motor structure that utilizes a detachable motor that can be detached from the main body for self-testing, thereby saving time and manpower for assembly and testing of the central motor structure.

In the embodiment of the present invention, the present invention provides a central motor structure, including: a main body, provided with a first through hole and a plurality of first lock holes; a gear set, accommodated in the main body; a detachable motor, including: a motor housing, detachably fixed to the main body, the motor housing having a second through hole corresponding to the first through hole, the motor housing including a box body, a cover body corresponding to the box body and provided with a plurality of second lock holes, the outer peripheral wall of the box body extending A plurality of wing blocks are extended, and a plurality of wing sheets are extended from the cover body opposite to the plurality of wing blocks, and a portion of each second lock hole is opened from each wing block, and another portion is opened from each wing sheet; and a drive motor is accommodated inside the motor housing, and the drive motor includes a drive shaft exposing the second through hole, and the drive shaft can be passed through the first through hole and engage with the gear set; and a plurality of screws are passed through and lock each first lock hole and each second lock hole.

Based on the above, the detachable motor can be assembled or disassembled from the main body, so that the detachable motor can be tested and pass the yield test by itself. When the yield test of the central motor structure is not outdated, the gear set can be directly replaced without replacing the detachable motor, thereby reducing the number of component replacements, thereby reducing the assembly and testing time of the central motor structure, and saving the assembly and testing manpower of the central motor structure.
