Description

Technical Field

[0001] The present case relates to a motor structure, specifically, a stator structure and a fan applicable thereto, which absorbs vibration energy by providing deformation with multi-directional degrees of freedom through at least two elastic parts, reduces vibration transmission, and improves the efficiency of fan operation. Background Art

[0002] Generally speaking, a fan mainly generates a guided airflow by driving a blade assembly to rotate by a motor. However, when the blade assembly is driven by a motor to rotate, vibration is easily generated.

[0003] Traditional motors use seismic isolation materials to be added to the assembly structure between the base body and the shell cover to achieve a better seismic isolation effect. However, it needs to be correctly aligned during assembly, which makes assembly difficult and time-consuming, and increases the overall cost. In addition, there are also seismic isolation solutions that install seismic isolation materials around the motor, but the assembly parts and seismic isolation materials are prone to poor contact, resulting in poor seismic isolation effects, and the seismic isolation materials need to be assembled separately on all sides, which consumes time.

[0004] In other words, it is rare to see a vibration-absorbing mechanism in the base body of the current motor. The base body that carries the stator often needs to be assembled with rubber, silicone and other vibration-isolating materials to achieve the effect of reducing vibration transmission. However, the effect is not good, and rubber and silicone need to be completed through an additional assembly process, which consumes manpower and time.

[0005] In view of this, it is necessary to provide a stator structure and a fan applicable thereto, which absorbs vibration energy by providing multi-directional deformation with at least two elastic members, reduces vibration transmission, improves the efficiency of fan operation, and solves the deficiencies of the prior art. Utility Model Content

[0006] The purpose of this case is to provide a stator structure and a fan applicable thereto, which absorbs vibration energy by providing deformation with multiple degrees of freedom in multiple directions through at least two elastic members, reduces vibration transmission, and improves the efficiency of fan operation.

[0007] Another object of the present invention is to provide a stator structure and a fan applicable thereto. At the bottom of the base body of the stator structure, two elastic members are arranged at intervals at the bottom of the outer peripheral wall. The two elastic members provide radial and circumferential support forces along the outer peripheral wall relative to the axial direction of the rotating shaft through the difference in the deformation segment structure, so as to absorb vibration energy through deformation with multiple degrees of freedom in multiple directions, reduce vibration transmission, and improve the efficiency of fan operation. In addition, when the base body of the stator structure is fixed between the base and the shell cover of the fan, the positioning structure on the bottom surface of the elastic member can be aligned with the positioning structure of the base, and the positioning structure on the top surface of the base body can be aligned with the positioning structure of the shell cover. When the base and the shell cover are assembled up and down, the stator structure is firmly fixed therein. On the other hand, the base body adopts a two-piece design of a main body and a rear cover body, and a heat dissipation metal plate can be embedded in the main body to enhance the heat dissipation efficiency of the stator assembly. The circuit board connected to the stator assembly is sandwiched between the main body and the rear cover body, and then led out through the external terminal of the outer peripheral wall. The external terminal can be disposed adjacent to the elastic member providing circumferential support force. Thus, the stator structure provides stable support when the fan is running, reduces vibration transmission, and improves the efficiency of the fan operation.

[0008] Another object of the present invention is to provide a stator structure and a fan applicable thereto. Vibration energy of a laterally arranged stator structure is absorbed by providing deformation with multiple degrees of freedom in at least two elastic members, and the rotating shaft penetrating the stator structure is more suitable for arranging blade groups in front and behind the stator structure to construct a single-axis two-way air outlet fan. When the stator structure is fixed between the base and the shell cover of the fan and is located between the laterally arranged front and rear blade groups, the two elastic members further provide deformation with multiple degrees of freedom in the axial direction of the rotating shaft to buffer vibration and improve the efficiency of the fan operation.

[0099] refer to Figures 1 to 7. The present case provides a stator structure 2 and a fan 1 applicable thereto, which absorbs vibration energy through deformation with multiple degrees of freedom in multiple directions, reduces vibration transmission, and improves the operating efficiency of the fan 1. In this embodiment, the fan 1 includes a stator structure 2, a rotating shaft 60, a rotor structure 61, and blade groups 62a, 62b. The stator structure 2 includes a base body 10, a plurality of stator poles 31, a circuit board 20, a first elastic member 40, and a second elastic member 50. The base body 10 includes a front end 101, a rear end 102, an outer peripheral wall 12, and a through opening 11, wherein the front end 101 and the rear end 102 are two opposite ends of the base body 10 in the axial direction C. The through opening 11 penetrates the area surrounded by the front end 101 and the area surrounded by the rear end 102 along the axial direction C, and the outer peripheral wall 12 is an outer surface connected between the front end 101 and the rear end 102. A plurality of stator poles 31 are arranged at the front end 101 of the base body 10 in a circumferential manner with the axial direction C as the center, and the winding group 32 is correspondingly wound around each stator pole 31 to form a stator assembly 30. The circuit board 20 is arranged on the base body 10, electrically connected to the stator assembly 30, and assembled to control the magnetism of the plurality of stator poles 31. The first elastic member 40 and the second elastic member 50 are respectively arranged adjacent to the bottom of the outer peripheral wall 12, spaced from each other, and respectively located on the left and right sides of the bottom of the outer peripheral wall 12. The two ends of the first elastic member 40 are connected to the outer peripheral wall 12 of the base body 10, and the assembly provides a first supporting force F1 to support the base body 10 along the radial direction of the outer peripheral wall 12. The two ends of the second elastic member 50 are also connected to the outer peripheral wall 12 of the base body 10, and the assembly provides a second supporting force F2 to support the base body 10 along the circumferential direction of the outer peripheral wall 12. In other words, the first elastic member 40 and the second elastic member 50 are arranged at intervals at the bottom of the outer peripheral wall 12. Through the difference in the deformation segment structure, the radial and circumferential support forces along the outer peripheral wall 12 are provided relative to the axial direction C of the rotating shaft 60, so as to absorb the vibration energy of the stator structure 2 by deformation with multiple degrees of freedom in multiple directions, thereby reducing vibration transmission. The structural difference between the first elastic member 40 and the second elastic member 50 will be described later. In this embodiment, the rotating shaft 60 is pivotally connected to the stator assembly 30 of the stator structure 2 through the bearing 63, and the rotating shaft 60 is arranged along the axial direction C and aligned to the through opening 11. The rotor structure 61, for example, includes a cover 611 and a magnet 612, and the magnet 612 is arranged around the inner wall surface of the cover 611. The rotor structure 61 is connected to the rotating shaft 60 through the cover 611, and corresponds to the stator assembly 30 of the stator structure 2 in space, so that the magnet 612 surrounds the multiple stator poles 31 and the winding group 32 of the stator assembly 30. Thus, the rotor structure 61 can be driven by the stator assembly 30 of the stator structure 2 to rotate around the axial direction C. In this embodiment, the blade sets 62a and 62b are connected to the rotating shaft 60 and driven by the rotor structure 61 and the rotating shaft 60 to rotate and generate airflow.

[0100] In the present embodiment, the supporting force of the stator structure 2 with multiple degrees of freedom in multiple directions is mainly formed by the structural difference between the first elastic member 40 and the second elastic member 50. The first elastic member 40 includes a first head end 41, a first middle section 42 and a first tail end 43. The first head end 41 is directly connected to the first middle section 42 and the outer peripheral wall 12, the first tail end 43 is directly connected to the first middle section 42 and the outer peripheral wall 12, and the first head end 41, the first middle section 42 and the first tail end 43 are sequentially connected and extended in the direction surrounding the axial direction C. In addition, in the present embodiment, the second elastic member 50 includes a second head end 51, a second middle section 52 and a second tail end 53, wherein the second head end 51 is directly connected to the second middle section 52 and the outer peripheral wall 12, the second tail end 53 is directly connected to the second middle section 52 and the outer peripheral wall 12, and the second head end 51, the second middle section 52 and the second tail end 53 are sequentially connected and extended in the direction parallel to the axial direction C. In the present embodiment, the first middle section 42 has, for example, two positive bends and one reverse bend, and the bends of the first middle section 42 sequentially present positive bends, reverse bends, and positive bends. In another embodiment, the first middle section 42 has, for example, four positive bends and one reverse bend, and the bends of the first middle section 42 sequentially present positive bends, positive bends, reverse bends, positive bends, and positive bends. In the present embodiment, the second middle section 52 has two positive bends and two reverse bends, and the bends of the second middle section 52 sequentially present reverse bends, positive bends, positive bends, and reverse bends. In another embodiment, the second middle section 52 has four positive bends and two reverse bends, and the bends of the second middle section 52 sequentially present reverse bends, positive bends, positive bends, positive bends, positive bends, and reverse bends. In addition, the first middle section 42 and the second middle section 52 may, for example, respectively include a bottom surface (or XY plane) that is partially parallel to the outer peripheral wall 12, and are flush with each other to form a coplanar surface P, so as to facilitate assembly or fixation. Of course, the present invention is not limited to this. The first elastic member 40 and the second elastic member 50 can provide radial support force (i.e., the first support force F1) and circumferential support force (i.e., the second support force F2) along the outer peripheral wall relative to the axial direction C of the rotating shaft 60 through the difference in deformation segment structure and arrangement, so as to absorb vibration energy through deformation with multiple degrees of freedom in multiple directions, reduce vibration transmission, and improve the operating efficiency of the fan 1. Of course, in other embodiments, the length, width and bending structure combination of the first elastic member 40 and the second elastic member 50 can be adjusted according to actual application requirements. The present invention is not limited to this.

[0101] In this embodiment, the fan 1 further includes a base 70 and a shell cover 71, the stator structure 2 is fixed between the base 70 and the shell cover 71, and the base 70 and the shell cover 71 are assembled to form air inlets 73a, 73b, air outlets 74a, 74b and accommodating spaces 75a, 75b. The air inlets 73a, 73b are arranged adjacent to the stator structure 2, the air inlets 73a, 73b are connected to the air outlets 74a, 74b through the accommodating spaces 75a, 75b along the axial direction C, the blade groups 62a, 62b are accommodated in the accommodating spaces 75a, 75b, and the rotating shaft 60 passes through the air inlets 73a, 73b and is connected to the blade groups 62a, 62b.

[0102] It should be noted that, in this embodiment, the fan 1 is, for example, a single-axis bidirectional fan, including a front air inlet 73a, a rear air inlet 73b, a front air outlet 74a, a rear air outlet 74b, a front accommodating space 75a, a rear accommodating space 75b, a front blade group 62a, and a rear blade group 62b. The front air inlet 73a is disposed adjacent to the front end 101 of the base body 10, and the front air inlet 73a is connected to the front air outlet 74a along the axial direction C through the front accommodating space 75a. The rear air inlet 73b is disposed adjacent to the rear end 102 of the base body 10, and the rear air inlet 73b is connected to the rear air outlet 74b along the axial direction C through the rear accommodating space 75b. The front blade group 62a and the rear blade group 62b are respectively accommodated in the front accommodation space 75a and the rear accommodation space 75b, and the rotating shaft 60 passes through the stator assembly 30 and the base body 10 through the through hole 11, and the rotating shaft 60 passes through the front air inlet 73a to connect to the front blade group 62a; the rotating shaft 60 also passes through the rear air inlet 73b to connect to the rear blade group 62b. Since the base body 10 can absorb the vibration energy of the transversely configured stator structure 2 by providing multi-directional deformation with the first elastic member 40 and the second elastic member 50, the rotating shaft 60 that passes through the stator structure 2 transversely is more suitable for setting the front blade group 62a and the rear blade group 62b at the front and rear ends of the stator structure 2 to construct a single-axis two-way air outlet fan. When the stator structure 2 is fixed between the base 70 and the cover 71 of the fan 1 and is located between the front blade set 62a and the rear blade set 62b arranged transversely, the first elastic member 40 and the second elastic member 50 provide multi-directional freedom of deformation relative to the axial direction C of the rotating shaft 60 to buffer vibration and improve the operating efficiency of the fan 1. In other embodiments, the front fan structure or the rear fan structure can be omitted. For example, if the rear fan structure is omitted, the rotating shaft 60 may not pass through the through hole 11 or the base body 10. Of course, the present case is not limited to this.

[0103] In this embodiment, the outer surface of the first middle section 42 of the first elastic member 40 has a first positioning structure 44, which protrudes downward and is assembled and matched with the second positioning structure 702 of the base 70. In this embodiment, the outer surface of the second middle section 52 of the second elastic member 50 has a first positioning structure 54, which protrudes downward and is assembled and matched with the second positioning structure 703 of the base 70. In this embodiment, the outer surface of the first middle section 42 provided with the first positioning structure 44 and the outer surface of the second middle section 52 provided with the first positioning structure 54, for example, form a coplanar plane P. When the stator structure 2 is disposed on the base 70 through the base body 10, the first positioning structure 44 of the first elastic member 40 and the first positioning structure 54 of the second elastic member 50 can provide a positioning function and increase the stability of the stator structure 2 on the base 70. On the other hand, the base body 10 further includes a third positioning structure 14, which is disposed on the top surface of the outer peripheral wall 12, protrudes upward, and is assembled and matched with the fourth positioning structure 72 of the shell cover 71. The fourth positioning structure 72 is, for example, detachably spliced ​​to the shell cover 71. In this embodiment, the base 70 includes a first fastener 701, and the shell cover 71 includes a second fastener 711. The base 70 and the shell cover 71 can be assembled by engaging the first fastener 701 and the second fastener 711. The base 70 and the shell cover 71 are assembled to cover the outside of the base body 10, and the stator structure 2, the rotating shaft 60, the rotor structure 61, and the blade group 62a, 62b and other structures are arranged between the base 70 and the shell cover 71. It is worth noting that when the shell cover 71 and the base 70 are assembled by engaging the first fastener 701 and the second fastener 711, the third positioning structure 14, the first positioning structure 44 and the first positioning structure 54 are respectively located above and below the stator structure 2, providing a positioning function and increasing the stability of the stator structure 2. In this embodiment, the base 70 and the shell cover 71 can be assembled and locked by a fastener 76 such as a screw. Of course, the present case is not limited to this.

[0104] In the present embodiment, the base body 10 is a two-piece structure, including a main body 10a and a rear cover 10b. The main body 10a and the rear cover 10b are assembled with each other along the axial direction C to form the base body 10. The circuit board 20 is disposed between the main body 10a and the rear cover 10b. And the through hole 11 runs through the main body 10a and the rear cover 10b. In the present embodiment, the main body 10a includes a first snap fastener 103, and the rear cover 10b includes a second snap fastener 104. The main body 10a and the rear cover 10b are assembled by engaging the first snap fastener 103 and the second snap fastener 104 respectively. In addition, in the present embodiment, the first elastic member 40 and the second elastic member 50 are described as being disposed on the main body 10a, but the present case is not limited thereto.

[0105] In this embodiment, the main body 10a includes a metal plate 13, the through hole 11 passes through the through hole 131 of the metal plate 13, and the metal plate 13 has a plurality of heat dissipation columns 133, which face the front end 101 and the stator assembly 30, and are assembled to dissipate the heat generated by the stator assembly 30. In addition, in this embodiment, the through hole 131 of the metal plate 13 is further connected to the through hole 201 of the circuit board 20 to the through hole 11, allowing the shaft 60 to pass through. Of course, the present case is not limited to this.

[0106] In this embodiment, the stator assembly 30 has a plurality of conductive terminals 33, and the circuit board 20 has a plurality of conductive contact points 202. The plurality of conductive terminals 33 and the plurality of conductive contact points 202 are spatially opposite to each other, wherein the body portion 10a includes a plurality of insulating members 132 penetrating the metal plate 13, and the plurality of conductive terminals 33 of the stator assembly 30 are respectively electrically connected to the plurality of conductive contact points 202 on the circuit board 20 through the plurality of insulating members 132. Thus, the conductive terminals 33 are in corresponding contact with the conductive contact points 202 through the metal plate 13, and the conductive terminals 33 are not electrically connected to the metal plate 13.

[0107] In this embodiment, the stator structure 2 also includes an external terminal 21, which is arranged on the outer peripheral wall 12 of the base body 10, and the external terminal 21 is arranged adjacent to the second elastic member 50, and the external terminal 21 is not covered by the base 70 and the shell cover 71, wherein the circuit board 20 is electrically connected to the external terminal 21. Since the circuit board 20 connected to the stator assembly 30 is sandwiched between the main body 10a and the rear cover 10b, it is then led out through the external terminal 21 of the outer peripheral wall 12. The external terminal 21 can be arranged adjacent to the second elastic member 50 that provides a circumferential support force (second support force F2). As a result, the stator structure 2 provides more stable support when the fan 1 is running, reduces vibration transmission, and improves the efficiency of the operation of the fan 1. Of course, the present case is not limited to this and will not be repeated.

[0108] In summary, the present invention provides a stator structure and a fan applicable thereto, which absorbs vibration energy through deformation with multiple degrees of freedom in at least two elastic members, reduces vibration transmission, and improves the efficiency of fan operation. At the bottom of the base body of the stator structure, two elastic members are arranged at intervals at the bottom of the outer peripheral wall. The two elastic members provide radial and circumferential support forces along the outer peripheral wall relative to the axial direction of the rotating shaft through the difference in the deformation segment structure, so as to absorb vibration energy through deformation with multiple degrees of freedom in multiple directions, reduce vibration transmission, and improve the efficiency of fan operation. In addition, when the base body of the stator structure is fixed between the base and the shell cover of the fan, the positioning structure on the bottom surface of the elastic member can be aligned with the positioning structure of the base, and the positioning structure on the top surface of the base body can be aligned with the positioning structure of the shell cover. When the base and the shell cover are assembled up and down, the stator structure is firmly fixed therein. On the other hand, the base body, for example, adopts a two-piece design of the main body and the rear cover body, and the main body can be embedded with a heat dissipation metal plate to enhance the heat dissipation efficiency of the stator assembly. The circuit board connected to the stator assembly is clamped between the main body and the rear cover, and then led out through the external terminal of the outer wall. The external terminal can be arranged adjacent to the elastic member that provides circumferential support force. As a result, the stator structure provides more stable support when the fan is running, reduces vibration transmission, and improves the efficiency of fan operation. Furthermore, by providing multi-directional freedom of deformation through at least two elastic members to absorb the vibration energy of the laterally configured stator structure, the rotating shaft that passes through the stator structure is more suitable for the front and rear blade groups of the stator structure to construct a single-axis two-way air outlet fan. When the stator structure is fixed between the base and the shell cover of the fan and is located between the laterally configured front and rear blade groups, the two elastic members provide multi-directional freedom of deformation relative to the axial direction of the rotating shaft to buffer vibration and improve the efficiency of fan operation.
