Detailed Description

As shown in fig. 1, a motor fixing mechanism includes a base 10, a motor accommodating groove 11 is formed in the base, a first positioning member 20 is hinged to the base, the first positioning member is provided with a first arc-shaped structure 21 for accommodating a motor, and the first positioning member is located on the left side of the motor accommodating groove; after the motor 30 accommodated in the first arc-shaped structure is pressed downwards into the motor accommodating groove by the first positioning element, the right side wall of the motor accommodating groove is abutted by the motor, and the axial lead of the motor is lower than the first hinge shaft 22 of the first positioning element and the base.

The operator places the motor 30 in the first arc-shaped structure 21, rotates the first positioning member 20 downwards, and blocks the motor into the motor accommodating groove 11, the left side of the motor is matched with the first arc-shaped structure 21, the right side of the motor is abutted against the right side wall of the motor accommodating groove 11, and the axial lead of the motor is lower than the first hinge shaft 22 of the first positioning member and the base, as shown in fig. 4.

As shown in fig. 1, the first positioning member 20 includes a first head 23, a first neck 24 engaged with the first head, a first body 25 engaged with the first neck, and a first hinge portion 26 engaged with the first body, the first hinge portion being engaged with the first hinge shaft 22, and the first arc-shaped structure 21 being located on the first neck. The first neck 24 is easily deformed to a certain extent, and the deformation can make the first positioning member 20 break through the stuck point and sink into the motor accommodating groove 11 when rotating downwards. The jamming point means that the shaft axis of the motor is at the same height as the first hinge shaft 22. At this time, the first hinge shaft is farthest away from the motor. After the clamping point is broken through downwards, the motor sinks into the motor accommodating groove 11. Due to the limitation of the motor receiving groove 11, the limitation of the first arc structure 21, and the limitation of the clamping point, the motor is difficult to be taken out of the motor receiving groove.

As shown in fig. 1, a second positioning member 40 is hinged on the base 10, the second positioning member is provided with a second arc-shaped structure 41 for accommodating the motor 30, and the second positioning member is located at the right side of the motor accommodating groove 11; after the motor 30 accommodated in the first arc-shaped structure is pressed downwards into the motor accommodating groove by the first positioning member 20, the motor abuts against the second arc-shaped structure, and the axial lead of the motor is lower than the second hinge shaft 42 of the second positioning member and the base. As shown in fig. 4. After the first positioning member presses the motor 30 into the motor accommodating groove 11, the right side of the motor abuts not only the second arc-shaped structure 41 but also the right side wall of the motor accommodating groove 11. The second arc structure 41 can restrict the motor from jumping out of the motor accommodating groove 11 as the first arc structure 11 does. Under the combined action of the first arc-shaped structure and the second arc-shaped structure, the motor is stabilized in the motor accommodating groove 11.

The upper part of the motor holding tank 11 is in a flaring shape, and the lower part of the motor holding tank is in a semicircular shape. The motor is clamped in the lower part of the motor accommodating groove. As an improvement, the lower half-round shape of the motor accommodating groove has a central angle larger than 180 degrees, so that the motor 30 needs to pass through the bayonet at the top of the half-round shape in the process of being clamped into the lower part of the motor accommodating groove, and the width of the bayonet is slightly smaller than the diameter of the half-round shape. The operator is used for acting on first locating piece 20, and first locating piece makes motor 30 force pass through the bayonet socket is sunk in the lower part of motor holding tank. In order to enable the motor to smoothly pass through the bayonet, the base 10 of the invention adopts a plastic part, or at least the motor accommodating groove 11 is made of a plastic material, so that the bayonet is elastically deformed to allow the motor to pass through. The bayonet and the bayonet point can be at the same height.

Alternatively, with reference to fig. 3 and 4, the second articulated shaft 42 is at the same height as the first articulated shaft 22, the second positioning element 40 has the same structure as the first positioning element 20, the first positioning element is in an upright position and the second positioning element is in an inverted position. In the process that the first positioning piece 20 downwardly clamps the motor into the motor accommodating groove 11, the motor 30 is located in the first arc-shaped structure 21 and the second arc-shaped structure 41, and the second arc-shaped structure can be matched with the first arc-shaped structure to press the motor into the motor accommodating groove 11. When the motor is located motor holding tank 11, the first arc structure of second arc structure cooperation restricts the motor and jumps out of motor holding tank 11. In the process that the motor is pulled out of the motor accommodating groove 11 upwards by the first positioning part 20, the motor drives the second positioning part 40 to rotate downwards, and the second positioning part assists the first positioning part to pull out the motor from the motor accommodating groove 11.

As a modification, as shown in fig. 5, after the first positioning member 20 presses the motor 30 accommodated in the first arc-shaped structure 21 downward into the motor accommodating groove 11, a connecting member 50 is connected between the first positioning member and the second positioning member 40. The two ends of the connecting piece 50 can be installed on the first positioning piece and the second positioning piece through the threaded connecting piece, so that the two positioning pieces are limited to rotate, and the position of the motor 30 in the motor accommodating groove 11 is further stabilized.

As a modification, as shown in fig. 1, the first positioning member 20 is provided with a polygonal hole 27. When the operator rotates the first positioning member 20 downward, a wrench or other rod-shaped tool can be matched in the polygonal hole to lengthen the force arm for rotating the first positioning member, thereby achieving the effect of saving power.
