DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Example 1

[0025] As Figure 1 shown:

[0026] A protection device for a mechatronic motor, comprising a base body 1, a protective cover 2 provided on the upper surface of the base body 1, and engaging mechanisms 3 arranged symmetrically between the base body 1 and the protective cover 2. Inside the protective cover 2, a motor body 4 and a placement mechanism 5 are respectively provided.

[0027] In this implementation: The existing device {Publication (Announcement) Number}: CN215580657U discloses a protection device for a mechatronic motor. This patent discloses a protection device for a mechatronic motor proposed in this application document. The engaging mechanism 3 and the placement mechanism 5 in this application document adopt the same technical means as those in this existing technology. These technical means will not be elaborated here one by one. Regarding this existing main body, this application makes further improvements. For details, refer to the disclosed technology below; To solve the technical problems existing in this existing technology, as disclosed in the background technology above, "When the above design is used, it effectively protects the drive motor, thereby avoiding the lack of effective protection for the drive motor. When in use, it is vulnerable to collision by external objects, resulting in malfunctions of the drive motor. However, due to the relatively sealed protection, the heat dissipation effect is poor. In some areas with relatively high temperatures, the phenomenon of motor burnout is likely to occur, seriously affecting the service life of the motor and reducing the use effect of the device." In combination, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a heat dissipation component 6 and an adjustment component 7 are added to this application document. All the power equipment involved in this product is powered by an external power supply.

[0028] It should be noted that: The accessories used in the engaging mechanism 3 and the placement mechanism 5 have been disclosed in Publication No. CN215580657U, and their use effects can be referred to Publication No. CN215580657U (that is, the "protective cover, plug block, sliding sleeve, limiting spring, clamping plate, pull rod, positioning rod, placement device, limiting seat, connecting block, mounting block, rotating block, fixing spring, fixing rod, square plate components" disclosed in this existing technology).

[0029] Furthermore:

[0030] As Figures 1-4 shown:

[0031] A heat dissipation component 6 is installed on the protective cover 2. The heat dissipation component 6 includes an exhaust fan 601 provided on one side of the protective cover 2, a metal plate 605 provided on the top of the exhaust fan 601, and a magnet block 606 fixed on the upper surface of the protective cover 2 near one side of the metal plate 605;

[0032] A sliding groove adapted to the metal plate 605 is provided inside the protective cover 2. The metal plate 605 and the protective cover 2 are slidably connected through this sliding groove. Limiting blocks 604 are fixed on both sides of the exhaust fan 601, and the limiting blocks 604 and the protective cover 2 are slidably connected through this sliding groove.

[0033] In this embodiment: When the motor body 4 is running, the exhaust fan 601 is started, and the heat inside the protective cover 2 is discharged outward through the exhaust fan 601, thereby improving the heat dissipation effect, avoiding the phenomenon of motor burnout caused by high-temperature areas, increasing the service life of the motor, and improving the use effect of the device. By pulling the metal plate 605 to move, the exhaust fan 601 is driven to move, and the exhaust fan 601 drives the limiting blocks 604 to move. Through this operation, the position of the exhaust fan 601 can be adjusted so that the position of the exhaust fan 601 corresponds to the heat dissipation position at the tail of the motor body 4, thereby accelerating the heat dissipation effect and the fluidity of heat.

[0034] Furthermore;

[0035] In an alternative embodiment, a blocking plate 602 is provided inside the sliding groove. Compression springs 603 arranged symmetrically are fixed between the blocking plate 602 and the base body 1. A rectangular groove adapted to the blocking plate 602 is provided inside the base body 1, and the blocking plate 602 and the base body 1 are slidably connected through this rectangular groove.

[0036] In this embodiment: By pulling the metal plate 605 to move, the limit on the exhaust fan 601 is released. At this time, the compression spring 603 rebounds and drives the blocking plate 602 to move upward, which can synchronously block the bottom position of the exhaust fan 601 to prevent excessive dust from entering.

[0037] It should be noted that: The metal plate 605 is made of a magnetically adsorbing metal material, and the magnetic adsorption force between the magnet block 606 and the metal plate 605 is greater than the maximum compression and rebound force of the compression spring 603.

[0038] Furthermore;

[0039] In an alternative embodiment, fixing plates arranged symmetrically are fixed on one side of the protective cover 2, and a shielding plate 607 is arranged between the fixing plates arranged symmetrically. The shielding plate 607 and the fixing plates are rotatably connected through a rotating shaft 608. A return torsion spring 609 is wound around the surface of the rotating shaft 608, and both ends of the return torsion spring 609 are fixed to the shielding plate 607 and the fixing plates respectively. Two groups of symmetrically arranged placement grooves are provided on one side of the surface of the protective cover 2, and threaded sleeves 610 are arranged in the placement grooves. The threaded sleeves 610 and the inner wall of the placement grooves are hinged through hinge shafts. A threaded rod 611 is threadedly connected inside the threaded sleeve 610, and insertion holes adapted to the threaded rod 611 are provided on the surface of the shielding plate 607.

[0040] In this embodiment: The exhaust fan 601 can be limited by the limiting block 604, making the exhaust fan 601 more stable during the moving process. When it rains, by rotating the threaded rod 611, the threaded rod 611 is removed from the insertion hole opened in the shielding plate 607, and at the same time, the threaded rod 611 drives the threaded sleeve 610 to be folded into the placement groove. At this time, under the elastic reset of the reset torsion spring 609, the shielding plate 607 rotates at an angle on the rotating shaft 608, so as to block one side of the protective cover 2, thereby preventing rainwater from entering the inside of the protective cover 2 and seeping into the inside of the motor body 4, which may cause the motor body 4 to short-circuit and affect the service life of the running motor body 4. Through this structure, the protection effect of the motor body 4 is further improved. This structure is more flexible and practical, meeting the actual use requirements.

[0041] Furthermore;

[0042] In an optional embodiment, a sound-absorbing plate 612 is fixedly installed on the inner side wall of the protective cover 2.

[0043] In this embodiment: During the operation of the motor body 4, the sound-absorbing plate 612 can absorb sound waves, reduce the noise reflection and diffusion generated by the motor body 4, and make the inside of the protective cover 2 quieter.

[0044] Further;

[0045] In an optional embodiment, an adjustment assembly 7 is installed on the base body 1. An adjustment lead screw 701, moving blocks 702 arranged symmetrically on the surface of the adjustment lead screw 701 in a threaded connection manner, and a strip plate 703 fixed on the upper surface of the moving blocks 702 are arranged inside the adjustment assembly 7. The adjustment lead screw 701 is rotationally connected to the base body 1 through a bearing. A limiting groove is opened on the surface of the base body 1, and the adjustment lead screw 701 is located in the limiting groove. The moving blocks 702 are slidably connected to the base body 1 through this limiting groove;

[0046] The lower surface of the strip plate 703 is installed with moving wheels 704 arranged symmetrically through bolts, and a plurality of groups of equally spaced installation holes 705 are opened on the surface of the strip plate 703.

[0047] In this implementation scheme: First, rotate the adjusting screw rod 701, thereby driving the moving block 702 to move. The moving block 702 drives the strip plate 703 to move. While the strip plate 703 is moving, it drives the moving wheel 704 to move. The moving wheel 704 can locally support the strip plate 703, making the support of the strip plate 703 more stable. Thus, the distance between the two strip plates 703 can be adjusted, so that motors of different sizes can be installed. This structure is more flexible and applicable, meeting the actual usage requirements. The installation can be achieved through bolts via the installation holes 705.

[0048] It should be noted that the threads of the adjusting screw rod 701 are designed symmetrically and oppositely, and can drive the two moving blocks 702 to move away from or close to each other.

[0049] Working principle and usage process of the present utility model: When using this protection device for mechatronic motors, first rotate the adjusting screw rod 701, which in turn drives the moving block 702 to move. The moving block 702 drives the strip plate 703 to move. While the strip plate 703 is moving, it also drives the moving wheel 704 to move. The moving wheel 704 can locally support the strip plate 703, making the support of the strip plate 703 more stable. Thus, the distance between the two strip plates 703 can be adjusted, so as to be applicable to the installation of motor bodies 4 of different sizes. This structure is more flexible and applicable, meeting the actual usage requirements. The installation can be achieved through bolts via the installation holes 705. After the distance between the two strip plates 703 is adjusted to an appropriate position, then install the motor body 4 on the strip plate 703 through the placement mechanism 5. Subsequently, install the protective cover 2 on the base body 1 through the clamping mechanism 3. When the motor body 4 is operating, start the exhaust fan 601. The exhaust fan 601 discharges the heat inside the protective cover 2 to the outside, thereby improving the heat dissipation effect and avoiding the phenomenon of the motor being burned due to high-temperature areas, increasing the service life of the motor and improving the usage effect of the device. By pulling the metal plate 605 to move, the limit on the exhaust fan 601 is released. At this time, the compression spring 603 rebounds and drives the plugging plate 602 to move upward. The movement of the plugging plate 602 drives the exhaust fan 601 to move, and the exhaust fan 601 drives the limit block 604 to move. The limit block 604 can limit the exhaust fan 601, making the movement of the exhaust fan 601 more stable during the movement. Through this operation, the position of the exhaust fan 601 can be adjusted so that the position of the exhaust fan 601 corresponds to the heat dissipation position at the tail of the motor body 4, thereby accelerating the heat dissipation effect and accelerating the fluidity of heat. Since the magnet block 606 adsorbs and fixes with the metal plate 605 by its own magnetism, the position of the exhaust fan 601 is fixed. During the operation of the motor body 4, the sound-absorbing plate 612 can absorb sound waves, reducing the noise reflection and diffusion generated by the motor body 4, making the inside of the protective cover 2 quieter. When it rains, rotate the threaded rod 611, so that the threaded rod 611 moves out of the jack opened on the shielding plate 607. At the same time, drive the threaded sleeve 610 to fold into the placement groove with the threaded rod 611. At this time, under the elastic reset of the reset torsion spring 609, the shielding plate 607 rotates at an angle on the rotating shaft 608, thereby blocking one side of the protective cover 2, so as to prevent rainwater from entering the inside of the protective cover 2 and seeping into the inside of the motor body 4, which may cause the motor body 4 to short-circuit and affect the service life of the motor body 4. Through this structure, the protection effect of the motor body 4 is further improved. This structure is more flexible and practical, meeting the actual usage requirements.

[0050] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
