[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1 - Figure 8 As shown, the present invention is a hollow cup motor that can reduce vibration, including a base 1, a protective shell 2 is provided on the top of the base 1, the protective shell 2 serves to protect the motor body 3, a protective cover 7 is installed on one end of the protective shell 2, the protective cover 7 cooperates with the protective shell 2 to facilitate the installation and protection of the motor body 3, the motor body 3 is installed inside the protective shell 2, the motor body 3 is the hollow cup motor, and a vibration damping component 4 is provided on the base 1.

[0035] The vibration damping assembly 4 includes a heat dissipation frame 41 fixedly installed on the side of the base 1 near the protective shell 2. The heat dissipation frame 41 serves to limit and stabilize the vibration damping plate 42. The vibration damping plate 42 is slidably installed inside the heat dissipation frame 41. A support plate 43 is fixedly installed on the side of the vibration damping plate 42 away from the base 1. The protective shell 2 is fixedly installed on the support plate 43 for easy installation. A water bladder 44 is fixedly installed on the side of the vibration damping plate 42 away from the protective shell 2. A cooling water pipe 46 communicating with the water bladder 44 is fixedly installed on the side of the vibration damping plate 42 away from the water bladder 44. The water bladder 44 and the cooling water pipe 46 are interconnected. When the vibration damping plate 42 moves downward, it squeezes the water bladder 44, allowing the water inside the water bladder 44 to flow into the cooling water pipe 46, thus providing a damping effect. The vibration damping function serves to buffer and reduce vibration while simultaneously dissipating heat from the protective shell 2. Cooling water pipes 46 are wound around the outer surface of the protective shell 2. An exhaust pipe is fixedly installed on the side of the cooling water pipes 46 furthest from the base 1, facilitating cooling of the protective shell 2 and the motor body 3. A groove 410 is provided on the side of the base 1 near the damping plate 42. Two sliders 413 are slidably installed within the groove 410, and a first spring 414 (a tension spring) is fixedly installed between the two sliders 413. This spring buffers the vibration between the motor body 3, the protective shell 2, and the damping plate 42, thus providing a damping effect. The sliders 413 are rotatably mounted on the side furthest from the base 1. A rotating plate 45 is provided, with one end of the rotating plate 45 away from the slider 413 rotatably mounted on a damping plate 42. The rotating plate 45 drives the slider 413 to slide within the slide groove 410, simultaneously stretching the first spring 414. A mounting frame 47 is fixedly mounted on the end of the protective shell 2 away from the protective cover 7. A fan 48 is rotatably mounted within the mounting frame 47. The protective shell 2 has ventilation holes 411, allowing the fan 48 to blow air and dissipate heat. A guide rod 412 is slidably mounted through the slider 413, with both ends of the guide rod 412 fixedly mounted on the inner wall of the slide groove 410. The guide rod 412 serves to limit and guide the slider 413. The first spring... The guide rod 412 is nested on the outer surface of the guide rod 412. The guide rod 412 serves to limit and stabilize the first spring 414. The water in the water bag 44 and the cooling water pipe 46, together with the first spring 414, counteracts the vibration and impact force. The overall weight of the device acts as damping to counteract the reverse elastic force of the first spring 414. A heat dissipation aluminum fin 49 is rotatably mounted on the outer surface of the motor body 3. The heat dissipation aluminum fin 49 dissipates heat from the motor body 3, which facilitates both vibration reduction and cooling of the motor body 3. This improves the device's vibration reduction capability, heat dissipation effect, protection capability, and safety and stability.

[0036] Example 2

[0037] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, based on Embodiment 1, an elastic component 5 is provided inside the protective shell 2. The elastic component 5 includes a telescopic rod 51 fixedly installed on the inner wall of the protective shell 2. The telescopic rod 51 serves to support and stabilize the dome 54 and the second spring 53. A damper 52 is fixedly installed on the telescopic rod 51, which counteracts the reverse elastic force of the second spring 53. A dome 54 is fixedly installed at the other end of the telescopic rod 51. The dome 54 slides on the motor body 3. The heat dissipation aluminum fins 49 rotate and clamp between the two rows of domes 54, which divides the domes 54 to facilitate heat dissipation. A second spring 53 is fixedly installed on the side of the dome 54 closest to the telescopic rod 51, and the end of the second spring 53 away from the dome 54... A rubber column 55 is fixedly installed on the inner wall of the protective shell 2. The rubber column 55 protects the motor body 3. The second spring 53 is nested on the outer surface of the telescopic rod 51. A third spring 56 is fixedly installed on the protective cover 7 near the protective shell 2. A top ring 57 is fixedly installed on the end of the third spring 56 near the protective shell 2. The third spring 56 drives the top ring 57 to press against the motor body 3, which plays a role in elastically limiting and stabilizing the motor body 3. This facilitates elastic vibration reduction operation in conjunction with the vibration damping component 4, which further improves the vibration reduction capability of the device and enhances the device's elastic vibration reduction capability, thereby improving the device's safety and stability.

[0038] Example 3

[0039] Please see Figure 1 - Figure 3As shown, based on Embodiment 1 and Embodiment 2, a limiting component 6 is provided on the protective cover 7. The limiting component 6 includes a limiting groove 61 formed on the protective cover 7. A limiting block 62 with a limiting hole 63 is fixedly installed on the side of the protective shell 2 near the protective cover 7. The limiting block 62 is inserted into the limiting groove 61, and at the same time, the limiting post 64 is inserted into the limiting hole 63, which plays the role of limiting and stabilizing the limiting block 62. A storage groove 65 is formed on the side of the protective cover 7 away from the protective shell 2. The storage groove 65 plays the role of storing the limiting block 62. The function of the positioning post 64 is to allow the positioning post 64 to slide through the storage slot 65 near the limiting slot 61. An operating plate 66 is fixedly installed on the side of the positioning post 64 away from the limiting slot 61. Under the action of the balance bar 67, the operating plate 66 slides within the storage slot 65, compressing the fourth spring 69 and the spring sheet 68, thus compressing them. The fourth spring 69 is fixedly installed on the side of the operating plate 66 away from the positioning post 64, and the end of the fourth spring 69 away from the operating plate 66 is fixedly installed on the storage slot 65. On the inner wall of the storage slot 65, spring clips 68 are rotatably mounted on both sides of the operating panel 66. The other end of the spring clips 68 is fixedly mounted on the inner wall of the storage slot 65. A balance bar 67 is slidably mounted through the operating panel 66. Both ends of the balance bar 67 are fixedly mounted on the inner wall of the storage slot 65. The balance bar 67 serves to balance and stabilize the operating panel 66. A winding reel 611 is rotatably mounted on the side of the protective cover 7 away from the protective shell 2. The winding reel 611 rotates to wind up the pull rope 610. The winding reel 611 and the operating panel 66... A pull rope 610 is fixedly installed between the parts. The pull rope 610 pulls the operating plate 66 under the action of the winding reel 611, causing the operating plate 66 to slide on the balance bar 67. This causes the operating plate 66 to wind the limiting post 64 into the storage slot 65, and at the same time, it causes the limiting post 64 to be removed from the limiting hole 63. This facilitates the installation and removal of the protective cover 7, and makes it easier to disassemble and maintain the motor body 3 inside the protective shell 2. This improves the installation and disassembly capabilities of the device, the work efficiency of device maintenance, and the protective capability of the device.

[0040] The working principle of this invention is as follows: When using the device, firstly, the motor body 3 is moved to drive the heat sink 49 into the protective shell 2, while simultaneously installing the heat sink 49 between the two rows of domes 54. At the same time, the motor body 3 is reversed to press the domes 54, causing the domes 54 to press the telescopic rod 51 and the second spring 53, thus compressing the telescopic rod 51 and the second spring 53. Simultaneously, the motor body 3 is in close contact with the domes 54. When the motor body 3 moves to the rubber column 55, the protective cover 7 is then moved and installed on the protective shell 2, causing the protective cover 7 to elastically move through the third spring 56 to the top ring 57. The motor body 3 is compressed, causing the third spring 56 to be in a compressed state. Simultaneously, the take-up reel 611 is rotated, causing it to wind up the pull rope 610. The pull rope 610 drives the operating plate 66 to slide on the balance bar 67, compressing the spring 68 and the fourth spring 69, thus compressing them. Simultaneously, the operating plate 66 drives the limiting post 64 to wind into the receiving slot 65, and the limiting block 62 is inserted into the limiting slot 61. Then, the take-up reel 611 is released, causing the operating plate 66 to move the limiting post under the reverse restoring force of the spring 68 and the fourth spring 69. 64 is inserted into the limiting hole 63, and then the motor body 3 is started. The vibration force of the motor body 3 is compressed by the dome 54 to press the telescopic rod 51 and the second spring 53, so that the damper 52 counteracts the reverse elastic force of the second spring 53, which facilitates buffering and vibration reduction. Then, the vibration force that the second spring 53 cannot completely counteract is driven by the support plate 43 to slide the damping plate 42 on the heat sink frame 41. At the same time, the damping plate 42 moves downward to press the rotating plate 45, and the rotating plate 45 drives the slider 413 to slide in the slide groove 410. At the same time, the slider 413 slides on the guide rod 412 to stretch the first spring. 414, the first spring 414 is in a stretched state, and the damping plate 42 squeezes the water bag 44, so that the water in the water bag 44 is squeezed into the cooling water pipe 46, so that the water in the cooling water pipe 46 cools the protective shell 2. At the same time, the fan 48 is started, so that the fan 48 dissipates heat from the heat dissipation aluminum fins 49 in the protective shell 2, so that cool air enters the protective shell 2 from the heat dissipation hole 411 and circulates to dissipate heat from the heat dissipation aluminum fins 49 and the motor body 3. At the same time, the dome 54 slides on the outer surface of the motor body 3, and the heat dissipation aluminum fins 49 swing between the two rows of domes 54 to dissipate heat.

[0041] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
