Description

Technical Field

[0001] This utility model relates to the field of anti-interference micro motor technology, and more specifically, it relates to an integrated anti-interference micro motor. Background Technology

[0002] Micro motors (micro motors) are a type of small and precise power device that plays a key role in fields such as automated equipment, precision instruments, and consumer electronics.

[0003] Patent document CN216312849U discloses an integrated anti-interference micro-motor. This device includes a motor body with several connecting wires on its top wall, first fixing ears on both side walls, a protective cover on the outer wall, and second fixing ears on the rear side walls of the protective cover. Limiting grooves are formed in the front walls of the two second fixing ears. A connecting mechanism, including a first screw and a second screw, connects the first and second fixing ears. This integrated anti-interference micro-motor relates to the field of motor equipment technology. The protective cover reduces motor noise during operation, and the shielding layer within the cover minimizes electromagnetic interference from external devices. Furthermore, the connecting mechanism facilitates the installation of the protective cover and the secure mounting of the motor.

[0004] However, after the device is installed, if the protective cover is damaged after prolonged use and needs to be removed, the entire micro-motor must be disassembled before the protective cover can be removed. This operation is cumbersome, wastes maintenance time, and reduces maintenance efficiency. Secondly, during the removal of the protective cover, multiple connecting wires pass through it. When the protective cover is pulled, the friction causes the protective cover to move and drag the connecting wires, which can also deform the connecting wires and easily damage them, thus reducing their service life.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an integrated anti-interference micro motor, comprising a motor body, a protective cover movably mounted on the outer side of the motor body, support plates fixedly mounted on both sides of the motor body, mounting holes on the support plates, a fixing chamber within the support plates, a bidirectional lead screw rotatably mounted within the fixing chamber, a throttle fixedly mounted at the upper end of the bidirectional lead screw passing through the fixing chamber, two movable seats threaded onto the bidirectional lead screw, a fixing block fixedly mounted at one end of the movable seats passing through the fixing chamber, the fixing block being L-shaped, four fixing seats mounted on the outer side of the protective cover, each fixing seat having a through hole cooperating with the fixing block, multiple connecting wires mounted on the motor body, an installation port on the protective cover, a limiting plate movably mounted within the installation port, multiple placement slots on the limiting plate and the installation port, and multiple connecting wires passing through the placement slots and extending to the outside of the protective cover.

[0009] The present invention is further provided with two limiting strips fixed inside the installation port to facilitate the limiting of the limiting plate.

[0010] The present invention is further provided with two mounting seats fixedly provided on the limiting plate to facilitate fixing the limiting plate.

[0011] The present invention is further configured such that the protective cover is provided with two mounting shells, and a screw is rotatably provided inside the mounting shell to facilitate the rotation of the screw.

[0012] The present invention is further configured such that a plug is threaded on the screw, one end of the plug is inserted into the mounting base, and one end of the screw passes through the mounting shell and is fixedly provided with a handle to facilitate the movement of the plug.

[0013] The present invention is further configured such that a positioning shell is fixedly provided on the support plate, and a push plate is movably provided inside the positioning shell, with one end of the push plate extending outside the positioning shell to facilitate the movement of the push plate.

[0014] The present invention is further provided with a spring fixed between one side of the push plate and the positioning shell to facilitate pushing the push plate.

[0015] The present invention is further configured such that a positioning rod is fixedly provided on the other side of the push plate, and a positioning hole is provided on the handle to cooperate with the positioning rod, so as to facilitate the limiting of the handle.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides an integrated anti-interference micro motor, which has the following beneficial effects:

[0018] 1. By using the motor body, protective cover, support plate, mounting hole, fixed chamber, double-acting screw, throttle, moving seat, fixing block, fixed seat and through hole in combination, the protective cover can be removed from the two support plates separately, which makes it easy to replace. The entire disassembly process does not require disassembling the entire motor body together, the operation is simple, and thus improves the efficiency of maintenance work.

[0019] 2. By using the connecting wire, mounting port, limiting plate, placement groove, limiting strip, mounting base, mounting shell, screw, plug rod and handle in combination, the limiting plate can be removed separately before removing the protective cover, thereby releasing the fixing of the connecting wire. This prevents the connecting wire from being pulled when removing the protective cover, protecting the connecting wire and extending its service life.

[0020] 3. The positioning shell, push plate, spring, positioning rod, and positioning hole work together to limit and fix the throttle after it is fixed, thereby preventing the throttle from rotating due to the vibration of the motor body during long-term use and ensuring the stability of the protective cover installation.

[0030] Please see Figure 1-5 An integrated anti-interference micro motor includes a motor body 1, a protective cover 2 movably mounted on the outside of the motor body 1, support plates 3 fixed on both sides of the motor body 1, mounting holes 4 on the support plates 3, a fixing chamber 5 inside the support plates 3, a bidirectional lead screw 6 rotatably mounted inside the fixing chamber 5, a throttle 7 fixedly mounted on the upper end of the bidirectional lead screw 6 passing through the fixing chamber 5, two movable seats 8 threaded on the bidirectional lead screw 6, a fixing block 9 fixedly mounted on one end of the movable seat 8 passing through the fixing chamber 5, the fixing block 9 being L-shaped, a fixing seat 10 on the outside of the protective cover 2, four fixing seats 10, each fixing seat 10 having a through hole 11 that mates with the fixing block 9, a positioning shell 22 fixedly mounted on the support plates 3, a push plate 23 movably mounted inside the positioning shell 22, one end of the push plate 23 extending outside the positioning shell 22, a spring 24 fixedly mounted between one side of the push plate 23 and the positioning shell 22, a positioning rod 25 fixedly mounted on the other side of the push plate 23, and a positioning hole 26 on the throttle 7 that mates with the positioning rod 25.

[0031] In this embodiment, when it is necessary to fix the protective cover 2 to the motor body 1, the protective cover 2 is moved to the outside of the motor body 1, so that the four fixing blocks 9 pass through the through holes 11 on the four fixing seats 10, and the fixing seats 10 contact the support plate 3, pushing the push plate 23. The push plate 23 drives the positioning rod 25 to move, so that the positioning rod 25 moves out of the positioning hole 26 in the throttle 7, and the spring 24 is compressed. At this time, the throttle 7 can be rotated, and the throttle 7 drives the bidirectional lead screw 6 to rotate. Since the bidirectional lead screw 6 is provided with two threaded areas in opposite directions, the two fixing blocks 9 move in the direction of separation. The L-shaped design of the fixing block 9 allows it to hook onto the fixing seat 10, thus securing it in place. This allows the protective cover 2 to be installed onto the motor body 1. After using the throttle 7, releasing the push plate 23 allows the spring 24 to push the positioning rod 25 into the positioning hole 26, positioning the throttle 7. The entire motor body 1 and the installed protective cover 2 can then be fixed together in the desired position via the mounting hole 4. To remove the protective cover 2, simply rotate the throttle 7 to release the fixing block 9 from the fixing seat 10, allowing the protective cover 2 to be removed separately. Since the sound insulation filling, shielding layer, heat dissipation vents, and sound insulation side plates on the protective cover 2 are already disclosed in patent publication number CN216312849U, entitled "Integrated Anti-interference Micro Motor," their specific structures and working principles are the same and will not be elaborated upon here.

[0032] Please see Figures 1-5 As one embodiment: the motor body 1 is provided with multiple connecting wires 12, the protective cover 2 is provided with a mounting port 13, a limiting plate 14 is movably provided in the mounting port 13, the limiting plate 14 and the mounting port 13 are respectively provided with multiple placement slots 15, the multiple connecting wires 12 pass through the placement slots 15 and extend to the outside of the protective cover 2, two limiting strips 16 are fixedly provided in the mounting port 13, two mounting seats 17 are fixedly provided on the limiting plate 14, two mounting shells 18 are provided on the protective cover 2, a screw 19 is rotatably provided in the mounting shell 18, a plug 20 is threaded on the screw 19, one end of the plug 20 is inserted into the mounting seat 17, and one end of the screw 19 passes through the mounting shell 18 and is fixedly provided with a handle 21.

[0033] More specifically, when installing the protective cover 2, multiple connecting wires 12 pass through the mounting port 13 and are placed into the placement slot 15 on the mounting port 13. The limiting plate 14 is inserted into the mounting port 13, and the two limiting strips 16 limit it. The limiting plate 14 drives the mounting base 17 to move, so that the mounting base 17 is aligned with the mounting shell 18. The handle 21 is turned, and the handle 21 drives the screw 19 to rotate. Since the screw 19 is threadedly connected to the insertion rod 20, the insertion rod 20 moves along the mounting shell 18. One end of the insertion rod 20 is inserted into the mounting base 17 to fix the mounting base 17. Thus, the limiting plate 14 is fixed into the mounting port 13 on the protective cover 2, and the multiple wire cups are fixed into the placement slot 15. When it is necessary to disassemble the protective cover 2, the limiting plate 14 can be removed first.

[0034] In summary, during the use or operation of the overall equipment: when it is necessary to fix the protective cover 2 to the motor body 1, move the protective cover 2 to the outside of the motor body 1, so that the four fixing blocks 9 pass through the through holes 11 on the four fixing seats 10, and the fixing seats 10 contact the support plate 3, pushing the push plate 23. The push plate 23 drives the positioning rod 25 to move, so that the positioning rod 25 moves out of the positioning hole 26 in the throttle 7, and the spring 24 is compressed. At this time, the throttle 7 can be rotated, and the throttle 7 drives the bidirectional lead screw 6 to rotate. Since the bidirectional lead screw 6 is provided with two threaded areas in opposite directions, the two fixing blocks 9 move in the direction of separation. The fixing block 9 is L-shaped, allowing it to hook onto the fixing seat 10 and secure it. This allows the protective cover 2 to be installed onto the motor body 1. After using the throttle 7, the push plate 23 is released. Under the push of the spring 24, the push plate 23 drives the positioning rod 25 into the positioning hole 26, thus positioning the throttle 7. The entire motor body 1 and the installed protective cover 2 can be fixed together to the desired installation position through the mounting hole 4. When the protective cover 2 needs to be removed, simply rotate the throttle 7 to release the fixing block 9 from the fixing seat 10, allowing the protective cover 2 to be removed separately. Since the sound insulation filling, shielding layer, heat dissipation vent, and sound insulation side plate on the protective cover 2 have been disclosed in patent publication number CN216312849U, entitled "Integrated Anti-interference Micro Motor," and their specific structure and working principle are the same, they will not be described in detail here.

[0035] When installing the protective cover 2, multiple connecting wires 12 will pass through the mounting port 13 and be placed into the placement slot 15 on the mounting port 13. The limiting plate 14 is inserted into the mounting port 13, and the two limiting strips 16 limit it. The limiting plate 14 drives the mounting base 17 to move, so that the mounting base 17 is aligned with the mounting shell 18. Turn the handle 21, and the handle 21 drives the screw 19 to rotate. Since the screw 19 is threadedly connected to the insertion rod 20, the insertion rod 20 moves along the mounting shell 18. One end of the insertion rod 20 will be inserted into the mounting base 17 to fix the mounting base 17. The limiting plate 14 can then be fixed into the mounting port 13 on the protective cover 2, and the multiple wire cups are fixed into the placement slot 15. When it is necessary to disassemble the protective cover 2, the limiting plate 14 can be removed first.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
