DETAILED DESCRIPTION

[0029] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0030] Example 1

[0031] like Figure 1-3As shown, a motor structure that can be easily disassembled and assembled includes a motor body 1, a mounting base 2 connected to the output shaft 11 of the motor body 1, and a connecting structure arranged between the motor body 1 and the mounting base 2, wherein the connecting structure includes a special-shaped clip 3 movably arranged on the mounting base 2 and a clamping member 4 arranged on the motor body 1; when the motor body 1 is assembled with the mounting base 2, the special-shaped clip 3 rotates relative to the mounting base 2 toward one end of the motor body 1 and elastically engages with the clamping member 4; when the motor body 1 is separated from the mounting base 2, the special-shaped clip 3 rotates toward the mounting base 2 and disengages from the clamping member 4.

[0032] In this embodiment, the motor body 1 and the mounting base 2 can be easily disassembled and assembled by the engagement of the special-shaped buckle 3 and the clamping piece 4. The operation is simple and convenient, and the problem of many parts, inconvenient disassembly and assembly, and maintenance caused by the screw fixing structure of the motor and the mounting base 2 is avoided.

[0033] Furthermore, an end cover 5 is provided at one end of the motor body 1 close to the mounting seat 2, and the clamping members 4 are respectively provided on two opposite sides of the end cover 5. Specifically, a shaft hole is provided in the middle of the end cover 5, through which the output shaft 11 of the motor body 1 passes.

[0034] Furthermore, a positioning piece is convexly provided on one end face of the end cover 5 facing the mounting seat 2, and the mounting seat 2 is correspondingly provided with a positioning hole 21 that cooperates with the positioning piece. Specifically, the number of the positioning pieces is two, and the two positioning pieces are respectively arranged above and below the shaft hole. The positioning piece is preferably a pin, and the end cover 5 is fixed in the positioning hole 21 of the mounting seat 2 by the pin, so that the motor body 1 and the mounting seat 2 are closely matched, preventing the motor body 1 from rotating left and right, and playing a better fixing role for the motor body 1.

[0035] Furthermore, the special-shaped buckle 3 includes a pull rod portion 31, a buckle portion 32 respectively arranged at both ends of the pull rod portion 31, and a holding portion 33 arranged at one end of the buckle portion 32 away from the pull rod portion 31, the holding portion 33 is used to be rotatably connected to the mounting seat 2, and the buckle portion 32 is used to elastically engage with the clamping member 4.

[0036] Furthermore, the pull rod portion 31 is U-shaped.

[0037] Furthermore, the buckle portion 32 is formed by bending the holding portion 33 toward one end of the pull rod portion 31 and then bending it in the opposite direction.

[0038] Furthermore, two opposite sides of the mounting seat 2 are provided with fixing pins 22 protruding outward, and the clamping portion 33 is rotatably connected to the fixing pins 22 .

[0039] Specifically, the special-shaped buckle 3 is preferably an integrally formed metal special-shaped buckle 3, and the special-shaped buckle 3 is a symmetrical structure with the central axis of the mounting seat 2 as the symmetry axis. The clamping portion 33 is annular, sleeved on the fixing pins 22 on both sides of the mounting seat 2, and can be flexibly rotated relative to the mounting seat 2 and the fixing pins 22. By setting the clamping portion 33 on the mounting seat 2, the special-shaped buckle 3 is prevented from falling off or being lost. The clamping portion 32 is formed by bending the clamping portion 33 toward one end of the pull rod portion 31 and then bending it in the reverse direction. The position where the clamping portion 32 is engaged with the clamping member 4 is at the inflection point of the bending and reverse bending. The pull rod portion 31 serves as a fulcrum. The pull rod portion 31 is pressed downward by hand to rotate it toward one end of the motor body 1 so that the buckle portion 32 engages with the snap connector 4 to achieve a stable connection between the motor body 1 and the mounting base 2. The pull rod portion 31 is lifted upward by hand to rotate it toward one end of the mounting base 2 so that the buckle portion 32 and the snap connector 4 are separated from each other to achieve separation of the motor body 1 and the mounting base 2. The operation is simple and convenient.

[0040] Furthermore, the clamping member 4 can rotate axially relative to the motor body 1 along the output shaft 11 thereof.

[0041] Furthermore, the clamping member 4 includes a roller fixing seat and a roller disposed on the roller fixing seat, the roller fixing seat is connected to the end cover 5, and the roller is clamped and connected with the special-shaped clamp 3. By preferably using the clamping member 4 as a roller, the friction when the special-shaped clamp 3 and the clamping member 4 are clamped can be reduced, and the wear of the clamping member 4 can be avoided.

[0042] Furthermore, a mounting hole 23 is provided in the middle of the mounting seat 2 for inserting the output shaft 11 of the power supply machine. Specifically, an assembly part that cooperates with the motor output shaft 11 is embedded in the mounting hole 23, and the motor output shaft 11 is connected to the assembly part, and the assembly part rotates together with the motor output shaft 11 to drive the external mechanism to rotate.

[0043] Example 2

[0044] The difference between this embodiment and embodiment 1 is that: Figure 4 As shown, this embodiment provides a motor structure that is easily disassembled and assembled, wherein the special-shaped clip 3 includes a pull rod portion 31, a clip portion 32 respectively arranged at both ends of the pull rod portion 31, and a holding portion 33 arranged at one end of the clip portion 32 away from the pull rod portion 31, the holding portion 33 is used for rotationally connecting with the mounting seat 2, and the clip portion 32 is used for elastically engaging with the clamping member 4.

[0045] Furthermore, the pull rod portion 31 is U-shaped.

[0046] Furthermore, the buckle portion 32 is formed by bending the holding portion 33 toward one end of the pull rod portion 31 and then bending it in the opposite direction.

[0047] Furthermore, a clamping protrusion 34 is provided on one end of the clamping portion 33 protruding toward the clamping member 4 .

[0048] Furthermore, the inner wall of the clamping protrusion 34 is arranged in an arc shape. When the motor body 1 and the mounting seat 2 are assembled, the inner wall of the clamping protrusion 34 is in contact with the outer wall of the clamping member 4; when the motor body 1 and the mounting seat 2 are separated, the end of the clamping protrusion 34 away from the clamping portion 33 is in contact with the clamping member 4. In this embodiment, the inner wall of the clamping protrusion 34 refers to a side wall of the clamping protrusion 34 close to the clamping member 4. The arrangement of the clamping protrusion 34 makes the elastic clamping of the special-shaped buckle 3 and the clamping member 4 more stable. When the motor body 1 and the mounting base 2 are separated from each other, the special-shaped clip 3 is pulled toward one end of the mounting base 2. At this time, the end of the convex portion 34 away from the retaining portion 33 conflicts with the snap-connector 4. On the one hand, it can limit the random swing of the special-shaped clip 3 and play a limiting role, making it more convenient for operators to operate during the disassembly and assembly of the motor; on the other hand, the convex portion 24 rotates relative to the fixing pin 22, and the convex portion 24 conflicts with the snap-connector 4 during the rotation, which is equivalent to applying an outward thrust to the snap-connector 4, thereby helping to separate the motor body 1 and the mounting base 2 from each other.

[0051] Furthermore, the hand-push body 6 is connected to the mowing mechanism 7 via a swing arm assembly 8, and the swing arm assembly 8 includes a plurality of swing arms 81 and a rotating arm 82, the upper ends of the plurality of swing arms 81 are connected to the hand-push body 6, the lower ends of the plurality of swing arms 81 are movably connected to the rotating arm 82, and the opposite side ends of the rotating arm 82 are detachably connected to the mowing mechanism 7.

[0052] Furthermore, at least one side end of the rotating arm 82 is provided with a socket 83 for inserting the output end of the power supply body 1. When the push-type body 6 and the mowing mechanism 7 are separated from each other, the output end of the motor body 1 can be directly inserted into the socket 83 of the rotating arm 82 after the motor body 1 is removed, which facilitates the placement of the motor body 1.

[0053] In some embodiments, a placement rack may also be provided at a suitable position of the hand-push body 6, and the placement rack can be used to place the motor body.

[0054] In some embodiments, a mounting groove may be provided at a suitable position of the hand-push body 6, and the mounting groove may allow the power supply body 1 or its output end to be placed or inserted.

[0055] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
