Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor protection technology, and in particular to an anti-collision structure for a magnetic levitation motor. Background Technology
[0002] As one of the core applications of magnetic levitation technology, the magnetic levitation motor achieves rotor levitation and drive through electromagnetic force, eliminating the need for traditional mechanical contact bearing support, thus greatly improving the motor's operating efficiency and reliability. However, in the actual application of magnetic levitation motors, since the magnetic levitation system essentially relies on precise electromagnetic control to maintain the rotor's levitation state, any external unexpected impact or vibration may disrupt this levitation balance, causing a collision between the rotor and stator. This collision not only causes physical damage to the motor, such as wear, deformation, or even breakage, but may also trigger turbulence in the electromagnetic system, affecting the motor's stable operation and performance output.
[0003] Existing servo motors are prone to collisions with other equipment during transportation, which can easily damage the servo motors. In addition, the servo motor body is prone to collisions with the support base, resulting in poor shock absorption.
[0004] The existing patent (publication number: CN221961666U) discloses an integrated servo motor anti-collision structure. This integrated servo motor anti-collision structure can achieve the purpose of shock absorption and anti-collision. The protective canopy protects the main body of the servo motor. After the support platform is unlocked, the second damper and the second buffer spring can play a role in shock absorption. After the movable seat is unlocked, the first damper, the first buffer spring and the support block can be used together to achieve the effect of buffering and anti-collision.
[0005] Existing patents offer solutions to the above problems, but they suffer from low overall protective strength. The protective canopy is easily deformed by external impacts, which can then squeeze the motor, thus reducing the motor's impact protection.
[0006] To address this, a collision-resistant structure for magnetic levitation motors is proposed. Utility Model Content
[0007] The purpose of this invention is to provide an anti-collision structure for a magnetic levitation motor, which can solve the problem that the existing motor anti-collision structures have low overall protection strength and the protective canopy is easily deformed by external force collisions, which can then squeeze the motor, thus reducing the anti-collision protection of the motor.
[0008] To achieve the above objectives, this utility model provides the following technical solution: an anti-collision structure for a magnetic levitation motor, including a mounting base, a motor body bolted to the top of the mounting base, an anti-collision mechanism provided at the top of the mounting base, and a horizontal adjustment mechanism provided at the bottom of the mounting base;
[0009] The anti-collision mechanism includes a baffle fixedly connected to the top of the mounting base. The baffle has a through-hole in the middle, and the output shaft of the motor body is located in the middle of the through-hole. A protective cover is provided on the top of the mounting base. The protective cover is located on the top of the motor body and is snapped into the baffle. Multiple reinforcing rods are fixedly connected to the inner wall of the protective cover. The other end of each reinforcing rod passes through the baffle, and a nut is threaded to one end of each reinforcing rod. The nut contacts the baffle. Multiple energy-absorbing components are provided on the side wall of the protective cover, and a ventilation protection component is provided on one side of the protective cover.
[0010] Preferably, the energy-absorbing component includes a plurality of support blocks fixedly connected to the side wall of the protective cover, two support blocks are arranged as a group, two support rods are fixedly connected between the two support blocks, and energy-absorbing plates are movably arranged on the side walls of the two support rods, the energy-absorbing plates being arc-shaped.
[0011] Preferably, the ventilation protection component includes a protective head disposed on the side wall of the protective cover, and a protective net is disposed on the side wall of the protective head, the protective net being adapted to the ventilation port of the motor body.
[0012] Preferably, the leveling mechanism includes four threaded cylinders fixedly connected to the four corners of the mounting base. The middle of each threaded cylinder is threaded with an adjusting foot, and the bottom of each adjusting foot is provided with a mounting foot. Mounting grooves are provided at the four corners of each mounting foot.
[0013] Preferably, a T-shaped block is rotatably connected to the middle of the mounting foot, and the T-shaped block is fixedly connected to the adjusting foot.
[0014] Preferably, the bottom of the mounting base is rotatably connected to a mounting plate, and a level is provided at the bottom of the mounting plate.
[0015] Preferably, the top of the mounting base is fixedly connected to two sliding frames, and the bottom of the protective cover is fixedly connected to two sliding strips, with the sliding frames and sliding strips being movably connected.
[0016] Preferably, the protective head is provided with dustproof cotton inside.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This application incorporates an anti-collision mechanism. A baffle is fixedly connected to the top of the mounting base and features a through-hole allowing the motor's output shaft to pass through, providing an initial protective barrier. A protective cover is located on top of the motor body, engaging with the baffle via a snap-fit mechanism and further secured by reinforcing rods and nuts, forming a robust protective layer that effectively resists external impacts. The combination of reinforcing rods and nuts ensures a stable connection between the baffle and the protective cover, enhancing the cover's protective strength and preventing deformation that could crush the motor body when subjected to external impact. This significantly improves the magnetic levitation motor's resistance to external impacts and effectively prevents motor damage caused by collisions.
[0019] 2. This application incorporates a leveling mechanism. This mechanism allows for fine-tuning of the mounting base's horizontal position by adjusting the adjusting feet in the threaded cylinder. This ensures that the motor can maintain horizontal operation even on uneven ground, preventing collisions between the rotor and stator inside the motor body, while also reducing vibration and noise.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1 to 5 This utility model provides a technical solution:
[0030] A collision prevention structure for a magnetic levitation motor includes a mounting base 1, a motor body 2 bolted to the top of the mounting base 1, a collision prevention mechanism 3 provided on the top of the mounting base 1, and a horizontal adjustment mechanism 4 provided on the bottom of the mounting base 1.
[0031] The anti-collision mechanism 3 includes a baffle 31 fixedly connected to the top of the mounting base 1. A through-hole 32 is provided in the middle of the baffle 31. The output shaft of the motor body 2 is located in the middle of the through-hole 32. A protective cover 33 is provided on the top of the mounting base 1. The protective cover 33 is located on the top of the motor body 2. The protective cover 33 is snapped into the baffle 31. Multiple reinforcing rods 34 are fixedly connected to the inner wall of the protective cover 33. The other end of the reinforcing rod 34 passes through the baffle 31. A nut 35 is threaded to one end of the reinforcing rod 34. The nut 35 contacts the baffle 31. Multiple energy-absorbing components 36 are provided on the side wall of the protective cover 33. A ventilation protection component 37 is provided on one side of the protective cover 33.
[0032] Specifically, such as Figure 2 As shown, the energy absorption assembly 36 includes multiple support blocks 361 fixedly connected to the side wall of the protective cover 33. Two support blocks 361 are arranged as a group, and two support rods 362 are fixedly connected between the two support blocks 361. Energy absorption plates 363 are movably arranged on the side walls of the two support rods 362. The energy absorption plates 363 are arc-shaped.
[0033] Specifically, such as Figure 3As shown, the ventilation protection component 37 includes a protective head 371 disposed on the side wall of the protective cover 33, and a protective net 372 disposed on the side wall of the protective head 371. The protective net 372 is adapted to the ventilation port of the motor body 2.
[0034] Specifically, such as Figure 4 As shown, the top of the mounting base 1 is fixedly connected to two sliding frames 8, and the bottom of the protective cover 33 is fixedly connected to two sliding bars 9. The sliding frames 8 and the sliding bars 9 are movably connected.
[0035] Specifically, such as Figure 3 As shown, the protective head 371 has a dustproof cotton 10 inside.
[0036] In use, the motor body 2 is installed on the top of the mounting base 1, and its output shaft passes through the through-hole 32 in the middle of the baffle 31 to ensure normal operation of the motor. The baffle 31 serves as the first line of defense, providing basic protection. The protective cover 33 is engaged with the baffle 31 by a snap-fit method and covers the motor body 2. One end of the reinforcing rod 34 is fixed to the inner wall of the protective cover 33, and the other end passes through the baffle 31 and is tightened with a nut 35 to form a stable support structure and enhance the stability of the protection. The bottom of the protective cover 33 is movably connected to the sliding frame 8 on the top of the mounting base 1 through the sliding strip 9, so that the protective cover 33 and the mounting base 1 are reinforced. When an external impact is applied to the protective cover 33, the energy-absorbing plate 363 moves on the support rod 362 and uses its arc-shaped structure to deform and absorb and disperse the collision energy, effectively reducing the impact on the motor body 2. The protective head 371 is set on the side wall of the protective cover, and the protective net 372 on it is adapted to the ventilation port of the motor body 2, which not only ensures the necessary heat dissipation of the motor, but also prevents external objects from entering the ventilation port and causing damage to the motor.
[0037] Specifically, such as Figure 5 As shown, the horizontal adjustment mechanism 4 includes four threaded cylinders 41 fixedly connected to the four corners of the mounting base 1. The middle of the threaded cylinder 41 is threadedly connected to an adjusting foot 42. The bottom of the adjusting foot 42 is provided with a mounting foot 43. The four corners of the mounting foot 43 are provided with mounting grooves 44.
[0038] Specifically, such as Figure 5 As shown, a T-shaped block 5 is rotatably connected to the middle of the mounting foot 43, and the T-shaped block 5 is fixedly connected to the adjusting foot 42.
[0039] Specifically, such as Figure 5 As shown, a mounting plate 6 is rotatably connected to the bottom of the mounting base 1, and a level 7 is provided at the bottom of the mounting plate 6.
[0040] In use, four threaded cylinders 41 are fixedly connected to the four corners of the mounting base 1. Each threaded cylinder 41 has an adjusting foot 42 threadedly connected to its middle. By rotating the adjusting foot 42, it can move up and down inside the threaded cylinder 41, thereby adjusting the height of the mounting base 1. The bottom of the adjusting foot 42 is provided with a mounting foot 43, which is used to contact the ground or other supporting surfaces. In the middle of the mounting foot 43, a T-block 5 is rotatably connected. The T-block 5 is fixedly connected to the adjusting foot 42, so that the adjusting foot 42 can remain stable and not easily shake when adjusting the height. The bottom of the mounting base 1 is also rotatably connected with a mounting plate 6, which can rotate relative to the mounting base 1 for easy adjustment of its position. At the bottom of the mounting plate 6, a level 7 is provided to check whether the mounting base 1 is in a horizontal state. By observing the indication of the level 7, the height of the four adjusting feet 42 can be precisely adjusted to make the mounting base 1 reach a horizontal state.
[0041] By adopting the above technical solution, the problem of low overall protective strength of existing motor anti-collision structures is solved. The protective canopy is easily deformed by external impacts, which can then squeeze the motor, thus reducing the anti-collision protection of the motor.
[0042] Working Principle: In use, the adjusting foot 42 is rotated to move it up and down within the threaded cylinder 41, thereby adjusting the height and level of the mounting base 1. The motor body 2 is mounted on top of the mounting base 1, and its output shaft passes through the through-hole 32 in the middle of the baffle 31 to ensure normal motor operation. The baffle 31 serves as the first line of defense, providing basic protection. The protective cover 33 is engaged with the baffle 31 via a snap-fit mechanism, covering the motor body 2. One end of the reinforcing rod 34 is fixed to the inner wall of the protective cover 33, and the other end passes through the baffle 31 and is tightened with a nut 35, forming a stable support structure and enhancing the stability of the protection. The bottom of the protective cover 33 is movably connected to the sliding frame 8 at the top of the mounting base 1 via a sliding strip 9, thus achieving a reinforced connection between the protective cover 33 and the mounting base 1. When an external impact acts on the protective cover 33, the energy-absorbing plate 363 moves on the support rod 362, using its arc-shaped structure to deform and absorb and disperse the collision energy, effectively reducing the impact on the motor body 2.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
