The motor 100 of the present invention includes: a rotor 1, a stator 2, a housing set 3, two pivoting members 4 and a cover 5. The rotor 1 comprises a shaft 11. The stator 2 can be held by the housing sleeve 3.
The housing kit 3 comprises: a housing body 31, three elastic arms 32 and three locking members 33. The number of the elastic arms 32 and the number of the locking members 33 included in the housing set 3 are not limited to the number shown in the drawings, and in practical applications, the number of the elastic arms 32 and the locking members 33 included in the housing set 3 may be increased according to the size of the stator 2.
Referring to fig. 3 to 8, fig. 7 is a schematic partial cross-sectional view of the housing body of the housing kit according to the present invention, and fig. 8 is a schematic cross-sectional view of the section line VIII-VIII of fig. 6. One end of the housing body 31 is concavely formed with a receiving groove 311. The housing body 31 has a plurality of first locking structures 312. The two ends of each elastic arm 32 are respectively a fixed end 321 and a free end 322, the fixed end 321 of each elastic arm 32 is fixed on the housing body 31, the free end 322 of each elastic arm 32 is not connected with the housing body 31, and each elastic arm 32 can be subjected to external force to elastically deform relative to the housing body 31. The free end 322 of each spring arm 32 is adjacent to the fixed end 321 of the other spring arm 32. Each of the elastic arms 32 has a second locking structure 323 at the free end 322, and each of the second locking structures 323 is disposed adjacent to one of the first locking structures 312.
Each locking member 33 is configured to cooperate with the second locking structure 323 of each elastic arm 32 and the adjacent first locking structure 312, so that the free end 322 of each elastic arm 32 and the housing body 31 are mutually fixed, and the plurality of elastic arms 32 and the housing body 31 together hold the stator 2 disposed in the accommodating groove 311.
More specifically, the housing body 31 has a cylindrical structure, and the housing body 31 includes a ring-shaped side wall 313 and an end wall 314, wherein the ring-shaped side wall 313 is connected with the periphery of the end wall 314, and the ring-shaped side wall 313 and the end wall 314 together form the accommodating groove 311. The ring sidewall 313 includes a plurality of through holes 3131 and a plurality of support structures 3132. Each through hole 3131 is provided through the ring sidewall 313. Each support structure 3132 is located between two adjacent through holes 3131, and each support structure 3132 extends toward an adjacent one of the through holes 3131 to form a resilient arm 32. Each elastic arm 32 has an arc structure, and each supporting structure 3132 extends outwards to form a first locking structure 312. The end of each spring arm 32 remote from the connection with the support structure 3132 is a free end 322. The second locking structure 323 formed at each free end 322 and the adjacent first locking structure 312 formed at the supporting structure 3132 form a gap G1 therebetween, and the distances between the gaps G1 are the same.
In practical applications, each first locking structure 312 may include a screw hole 3121, each locking member 33 may be a screw, for example, and each second locking structure 323 may include a through hole 3231, each screw may pass through each through hole 3231 to be locked with each screw hole 3121, so that the plurality of elastic arms 32 jointly hold the stator 2 disposed in the accommodating groove 311. In various embodiments, each of the first locking structures 312 and each of the second locking structures 323 may include a through hole, and the screw is matched with a nut, so that the first locking structure 312 and the adjacent second locking structure 323 are locked with each other.
Referring to fig. 9 and fig. 10 together, fig. 9 is a schematic cross-sectional view of the stator disposed in the housing body of the housing assembly according to the present invention, and the locking member is not locked; fig. 10 is a schematic cross-sectional view of the stator disposed in the housing body of the housing kit according to the present invention, and the locking member is locked. As shown in fig. 9, when the stator 2 is disposed in the accommodating groove 311 of the housing body 31 and each elastic arm 32 is not locked by the locking member 33, a gap G2 is formed between each elastic arm 32 and the stator 2, and a person can easily place the stator 2 in the accommodating groove 311, and a person can easily take out the stator 2 from the accommodating groove 311.
It should be noted that the manner of each elastic arm 32 shown in fig. 9 is only one exemplary manner, but not limited thereto, and the manner of each elastic arm 32 can be changed according to the requirement as long as the gap G2 is provided between each elastic arm 32 and the stator 2.
As shown in fig. 10, when each locking member 33 locks the adjacent first locking structure 312 and second locking structure 323, the inner side of each elastic arm 32 clamps the periphery of the stator 2, and the periphery of the stator 2 is held together by each elastic arm 32 and the ring sidewall 313, so that the stator 2 is difficult to move relative to the housing body 31.
As described above, the related person can hold the stator 2 by simply operating the plurality of locking members 33, or the stator 2 is not held by the housing body 31 any more, and the housing body 31 and the stator 2 will not be damaged in the process of fixing or separating the stator 2 and the housing body 31 from each other.
It should be noted that, as shown in fig. 9, in practical application, each support structure 3132 extends in a counterclockwise direction (or in a clockwise direction) to form the elastic arm 32, and 3 support structures 3132 are located at 3 equally divided positions of the ring sidewall 313 in a cross section (that is, the 3 support structures 3132 are located at 60 degrees, 90 degrees and 120 degrees respectively). When the shaft 11 rotates, it rotates around an axis CP (as shown in fig. 1), and the normal direction of the cross section is parallel to the axis. By the above design, the circumference of the stator 2 can be held by substantially the same force.
Referring to fig. 1 to 4, the cover 5 is detachably fixed to one end of the housing body 31 with the concave forming the accommodating groove 311, and the cover 5 and the housing body 31 can jointly form an accommodating space SP in which the stator 2 and the rotor 1 can be correspondingly disposed. Wherein, the housing body 31 and the cover 5 are respectively provided with a pivoting component 4, and two ends of the rotating shaft 11 of the rotor 1 are pivoted with the two pivoting components 4. The pivot component 4 is, for example, various kinds of pelargonides.
In summary, the motor and the housing kit thereof according to the present invention can enable a user to quickly and conveniently fix or separate the stator and the housing body from each other through the designs of the plurality of elastic arms, the plurality of locking structures, the plurality of locking members, and the like, and the stator is not damaged by any personnel during the process of separating the stator and the housing body from each other, and the stator can be reused after the related personnel take out the stator.
Since the stator and its housing are usually fixed to each other by a tight fit, the housing must be broken to remove the stator when a person tries to remove the stator, and the stator may be damaged during the process of breaking the housing, which may result in the stator not being reused.
The foregoing description is only of the preferred embodiments of the invention and is not intended to limit the scope of the invention, so that all equivalent technical changes made by the specification and drawings are included in the scope of the invention.
