Description

Technical Field

[0001] This application relates to the field of motor device technology, specifically a long-life acoustic motor. Background Technology

[0002] Compared to conventional motors, the rotor of a sonic motor does not perform continuous rotational motion, but rather small-amplitude reciprocating motion. Therefore, conventional brush structures cannot be used to energize the coils on the rotor; otherwise, the brushes will easily wear out and require frequent replacement and maintenance.

[0003] In the prior art, such as the magnetic vibration motor disclosed in patent application number 201821082271.6, the technical solution is "there are two taps 901 in the coil 9, and the two taps 901 are respectively connected to a fatigue-resistant energized wire 11, which can be connected by welding". Although the fatigue-resistant energized wire is used, it can avoid the wire from breaking to a certain extent as the rotor rotates back and forth at high frequency and small amplitude. However, after the coil taps and the fatigue-resistant energized wire are connected by welding, the coil is prone to breakage near the connection point, resulting in a short service life of this type of motor. Utility Model Content

[0004] This utility model addresses the above-mentioned problems by proposing a long-life acoustic motor, aiming to solve the technical problems in the background art.

[0005] To achieve the above objectives, this utility model provides a long-life acoustic motor, comprising:

[0006] A rotor assembly, comprising a rotating shaft, an iron core portion sleeved on the rotating shaft, and two sets of symmetrically arranged coils wound on the iron core portion; each of the two coils is provided with a terminal.

[0007] A connecting seat is provided with a connecting hole, which is fitted with the rotating shaft; the end face of the connecting seat is provided with two staggered wiring grooves, the inlets of the two wiring grooves are both located on the side wall of the connecting seat, and the outlets of the two wiring grooves are located on the end face of the connecting seat opposite to the opening of the wiring groove or on the side wall of the connecting seat.

[0008] The fatigue-resistant and breakage-proof wires are provided in pairs. The power supply terminals of the two fatigue-resistant and breakage-proof wires pass through the inlets of the two wiring troughs, extend out of the outlets of the wiring troughs, and are respectively connected to the two terminals.

[0009] A fastening cover is sleeved and connected to the rotating shaft, and the fastening cover is provided with a corresponding retaining wall plate that extends into the wiring groove; after the fastening cover is connected to the connecting seat, the retaining wall plate presses and fixes the fatigue-resistant and breakage-resistant wire in the wiring groove.

[0010] Furthermore, when the outlet of the wiring trough is located on the side wall of the connector, the connector is provided with a retaining arm corresponding to the connection between the wiring terminal and the power supply terminal.

[0011] Furthermore, the outer contour of the connector is circular, and the wiring groove is an arc-shaped groove corresponding to the contour of the connector.

[0012] Furthermore, the fastening cover has a rim wall that at least partially connects to and surrounds the side wall of the connecting seat, and the rim wall has a clearance notch to avoid the entrance of the wiring groove.

[0013] Further, it includes a motor housing, a rear cover, a limiting member, a first bearing, a second bearing, and a permanent magnet; the motor housing and the rear cover are detachably connected, and when connected, they enclose a receiving cavity; the permanent magnet is arranged in the receiving cavity; the rotating shaft is rotatably connected to the motor housing and the rear cover respectively through the first bearing and the second bearing, and one end of the rotating shaft extends out of the motor housing; the limiting member is disposed between the first bearing and the iron core portion; the fastening cover has a limiting portion that abuts against the inner ring of the second bearing.

[0014] Furthermore, the core section includes a core frame and insulating sleeves that are fitted over at least both ends of the core frame; the coil is wound on the core frame and the insulating sleeves;

[0015] Alternatively, the outer wall of the core frame is covered with an insulating layer, and the coil is wound on the outer wall of the insulating layer.

[0016] Furthermore, the connecting seat is also provided with a positioning retaining part for retaining the iron core; the positioning retaining part is connected to the iron core and is used to position the connecting seat and prevent the connecting seat from rotating relative to the rotating shaft;

[0017] Alternatively, the connecting seat has a plug-in post on the end face of the iron core, and the iron core has a plug-in hole corresponding to the plug-in post. The plug-in post is inserted into the plug-in hole to position the connecting seat and to prevent the connecting seat from rotating relative to the rotating shaft.

[0018] Furthermore, the insulating sleeve is provided with a baffle to hold the coil.

[0019] Furthermore, the rear cover is provided with a wire-passing hole for the fatigue-resistant and breakage-resistant wire to pass through, and the positions of the two wire-passing holes are matched and set close to the entrance positions of the two wiring channels.

[0020] Furthermore, when the outlet of the wiring trough is located on the side wall of the connector, the outlet extends to the end face of the connector opposite to the opening of the wiring trough.

[0021] Furthermore, the two wiring channels are arranged symmetrically.

[0022] Compared with the prior art, the long-life acoustic motor provided by this utility model can be connected to the rotating shaft through the connecting seat. After the fatigue-resistant and anti-breakage wire is fixed by the connecting seat and the fastening cover and is connected to the terminal, the end of the fatigue-resistant and anti-breakage wire is closer to the center of the rotating shaft. When it rotates with the rotor, the swing amplitude is smaller. Furthermore, the connection between the terminal and the power supply terminal 5, as well as the coil wire itself, will not be pulled by the rotation of the rotor. Only the fatigue-resistant and anti-breakage wire is affected by the rotation and swing, thereby improving the service life of the motor and reducing the trouble of frequent maintenance.

[0038] Please refer to Figures 1-11 This embodiment provides a long-life acoustic motor, including:

[0039] The rotor assembly includes a rotating shaft 1, an iron core 2 sleeved on the rotating shaft 1, and two sets of symmetrically arranged coils 3 wound on the iron core 2; each of the two coils 3 is provided with a terminal 310.

[0040] The connecting seat 4 has a connecting hole 410 for connecting the rotating shaft 1; the end face of the connecting seat 4 has two staggered wiring grooves 420, the inlets 421 of the two wiring grooves 420 are both located on the side wall of the connecting seat 4, and the outlets 422 of the two wiring grooves 420 are located on the end face of the connecting seat 4 away from the opening of the wiring grooves 420 or on the side wall of the connecting seat 4;

[0041] Two fatigue-resistant and breakage-resistant wires 5 are provided. The power supply terminals 510 of the two fatigue-resistant and breakage-resistant wires 5 pass through the inlets 421 of the two wiring troughs 420, and after passing through the channels of the wiring troughs 420, they extend out of the outlets 422 of the wiring troughs 420 and are respectively connected to the two terminals 310. The connection can be made by soldering.

[0042] The fatigue-resistant and breakage-resistant conductor 5 can be selected from existing technologies; for example, the fatigue-resistant and breakage-resistant conductor 5 can be a high-life electronic wire.

[0043] The fastening cover 6 is sleeved and connected to the rotating shaft 1, and the fastening cover 6 is provided with a corresponding retaining wall plate 610 extending into the wiring groove 420; after the fastening cover 6 is connected to the connecting seat 4, the retaining wall plate 610 presses and fixes the fatigue-resistant and breakage-resistant wire 5 in the wiring groove 420.

[0044] By connecting the connector 4 to the rotating shaft 1, the fatigue-resistant and anti-breakage wire 5 is fixed by the connector 4 and the fastening cover 6 and connected to the terminal 310. The end of the fatigue-resistant and anti-breakage wire 5 is closer to the center of the rotating shaft 1. When it rotates with the rotor, the swing amplitude is smaller. Furthermore, the connection between the terminal 310 and the power supply terminal 510, as well as the wire of the coil 3 itself, will not be pulled by the rotation of the rotor. Only the fatigue-resistant and anti-breakage wire 5 is affected by the rotation and swing, thereby improving the service life of the motor and reducing the trouble of frequent maintenance.

[0045] Furthermore, since the fastening cover 6 and the connecting seat 4 are fixed by the clamping wall plate 610 extending into the wiring groove 420 to press and fix the fatigue-resistant and anti-breakage wire 5 in the wiring groove 420, glue can be used to fix the fatigue-resistant and anti-breakage wire 5 to the connecting seat 4, thus reducing production costs.

[0046] In some embodiments, the connecting seat 4 is abutting the end face of the iron core 2 and is provided with a plug post 440. The iron core 2 is provided with a plug hole 230 corresponding to the plug post 440. The connecting seat 4 is fastened to the iron core 2 by inserting the plug post 440 into the plug hole 230.

[0047] Please refer to Figure 6 and Figure 7 When the outlet of the wiring trough 420 is located on the side wall of the connector 4, the connector 4 is provided with a retaining arm 430 at the connection point between the terminal 310 and the power supply terminal 510.

[0048] The guard arm 430 encloses the connection between the fatigue-resistant and anti-breakage wire 5 and the coil 3 to prevent external forces from accidentally hitting this point and causing adverse effects. This design is well thought out.

[0049] The stop arm 430 is located in the space between the two sets of coils 3. The terminals 310 of the coils 3 can be conveniently and easily positioned within the enclosure area of ​​the stop arm 430.

[0050] The outlet of the cable tray 420 is located on the side wall of the connecting seat 4, which facilitates manual or automated equipment operation for welding fatigue-resistant and breakage-resistant wires 5 and coils 3.

[0051] Please refer to Figure 6 The outer contour of the connector 4 is circular, and the wiring groove 420 is an arc-shaped groove corresponding to the contour of the connector 4.

[0052] This design makes good use of space and optimizes the space occupied by the connector 4.

[0053] Please refer to Figure 2 and Figure 8 , Figure 9The fastening cover 6 is provided with a rim wall 620 that at least partially connects to and surrounds the side wall of the connecting seat 4. The rim wall 620 is provided with a clearance notch 621 that avoids the entrance 421 of the wiring groove 420.

[0054] This design allows for a more secure and stable connection between the connector 4 and the fastening cover 6, and avoids interference with the routing of the fatigue-resistant and breakage-resistant wire 5.

[0055] Please refer to Figures 1-4 The device includes a motor housing 7, a rear cover 8, a limiting member 9, a first bearing 10, a second bearing 11, and a permanent magnet 12. The motor housing 7 and the rear cover 8 are detachably connected, and when connected, they enclose a receiving cavity. The permanent magnet 12 is arranged in the receiving cavity. The rotating shaft 1 is rotatably connected to the motor housing 7 and the rear cover 8 through the first bearing 10 and the second bearing 11, respectively, and one end of the rotating shaft 1 extends out of the motor housing 7. The limiting member 9 is located between the first bearing 10 and the iron core 2. The fastening cover 6 is provided with a limiting part 630, which abuts against the inner ring of the second bearing 11.

[0056] The iron core 2 is located within the receiving cavity. Within the receiving cavity, from the motor housing 7 to the rear cover 8, along the axial direction of the rotating shaft 1, the arrangement of these components is as follows: first bearing 10, limiting member 9, iron core 2, connecting seat 4, fastening cover 6, limiting member 630, and second bearing 11. These components, connected to the rotating shaft 1, abut against each other in pairs, precisely utilizing the required length of the rotating shaft 1 within the receiving cavity, thereby controlling the length of the rotating shaft 1 extending beyond the motor housing 7 and improving the dimensional accuracy of the motor manufacturing.

[0057] Please refer to Figure 5 The core portion 2 includes a core frame 210 and an insulating sleeve 220 that is sleeved at least at both ends of the core frame 210; the coil 3 is wound on the core frame 210 and the insulating sleeve 220.

[0058] Alternatively, please refer to Figure 10 , Figure 11 The outer wall of the iron core frame 210 is covered with an insulating layer, and the coil 3 is wound on the outer wall of the insulating layer.

[0059] The insulation layer can be coated onto the outer wall of the iron core frame 210.

[0060] Please refer to Figure 5 The insulating sleeve 220 is provided with a baffle 221 to hold the coil 3.

[0061] Baffle 221 prevents coil 3 from falling off and detaching from insulating sleeve 220.

[0062] Please refer to Figure 5 and Figure 10, Figure 11 The connecting seat 4 is also provided with a positioning holding part 450 for holding the iron core part 2; the positioning holding part 450 is connected to the iron core part 2 and is used to position the connecting seat 4, so as to prevent the connecting seat 4 from shaking and to stop the connecting seat 4 from rotating relative to the rotating shaft 1.

[0063] The positioning and holding part 450 can be a claw-shaped structure, with a holding groove formed between the claws that matches the structure of the iron core frame 210 covered with an insulating layer.

[0064] When the connecting seat 4 is equipped with a positioning and holding part 450, it is preferable that the core part 2 of the core frame 210 is covered with an insulating layer on its outer wall.

[0065] Please refer to Figure 3 and Figure 4 The rear cover 8 is provided with a wire hole 810 for the fatigue-resistant and anti-breakage wire 5 to pass through, and the two wire holes 810 are positioned close to the entrance positions of the two wiring channels 420.

[0066] This design prevents the fatigue-resistant and breakage-resistant wire 5 from bending excessively and avoids excessive friction with the wire hole 810.

[0067] Please refer to Figure 6 and Figure 7 When the outlet 422 of the wiring groove 420 is located on the side wall of the connecting seat 4, the outlet 422 extends to the end face of the connecting seat 4 away from the opening of the wiring groove 420.

[0068] This design makes it easier to connect the wiring terminal 310 of coil 3 to the power supply terminal 510 of fatigue-resistant and breakage-resistant wire 5, avoiding bending of the coil 3 wire.
