Description

Technical Field

[0001] This invention relates to the field of torque motor technology, and more specifically to a torque motor with a self-locking structure. Background Technology

[0002] A torque motor is a special type of motor with a large number of poles. It can continue to operate at low speeds or even when the rotor is stalled (i.e., the rotor cannot rotate) without causing damage to the motor. In this operating mode, the motor can provide a stable torque to the load (hence the name torque motor). A torque motor can also provide torque in the opposite direction of rotation (braking torque), therefore a self-locking structure is required.

[0003] However, the self-locking structure of existing torque motors generally uses a limit plug-in method. However, when the torque motor is powered off, the inertia of the connecting parts can easily damage the plug-in when it locks, affecting the service life of the plug-in and hindering the elastic self-locking of the device. This affects the user experience and the self-locking capability of the device. Therefore, based on the shortcomings of the technology, a torque motor with a self-locking structure that can solve the above problems is proposed. Summary of the Invention

[0033] 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.

[0034] Please see Figures 1-9 As shown, the present invention is a torque motor with a self-locking structure, including a base 1, a mounting bracket 3 fixedly installed on the top of the base 1, a torque motor body 2 installed between the base 1 and the mounting bracket 3, and a self-locking component 4 provided on the mounting bracket 3;

[0035] The self-locking assembly 4 includes a fixed frame 41 fixedly mounted on the side of the mounting bracket 3 away from the base 1. A first toothed sprocket 42 is rotatably mounted on the fixed frame 41. A groove 44 is provided on the side of the mounting bracket 3 near the fixed frame 41. A slide rod 45 with a second toothed sprocket 43 is slidably mounted in the groove 44. The second toothed sprocket 43 is fixedly mounted on the end of the slide rod 45 near the first toothed sprocket 42. The triangular blocks on the first toothed sprocket 42 and the second toothed sprocket 43 are interlocked to facilitate self-locking of the connecting parts on the first toothed sprocket 42. A limit block 46 is fixedly mounted on the end of the slide rod 45 away from the second toothed sprocket 43, which limits the movement of the slide rod 45. A rectangular... A rectangular through-hole 414 contains a rotating block 416 with a first spring 413 slidably mounted inside. A sliding ring 417 is slidably fitted onto the output end of the torque motor body 2. The sliding ring 417 is easily rotated and opened onto the output end of the torque motor body 2. The rotating block 416, attracted by the electromagnet 415, causes the sliding ring 417 to slide on the output end of the torque motor body 2. Simultaneously, the sliding ring 417 causes the first elastic plate 47 to slide on the first steering block 48 and the second steering block 49, and also causes the first elastic plate 47 to slide on the sliding roller 411. An electromagnet 415 is fixedly mounted on the inner wall of the rectangular through-hole 414 near the base 1. When the torque motor body 2 is de-energized, the electromagnet 415 is energized and attracts the rotating block 416, causing the rotating block 416 to slide on the first steering block 48 and the second steering block 49, and the first elastic plate 41 ... 16 slides within the rectangular through hole 414. A first elastic plate 47 is rotatably mounted on the side of the sliding ring 417 away from the rectangular through hole 414. The first elastic plate 47, under the direction of the second steering block 49, drives the sliding rod 45 to slide within the groove 44, causing the sliding rod 45 to drive the second toothed disc 43 towards the first toothed disc 42, so that the second toothed disc 43 and the first toothed disc 42 interlock and mesh, facilitating the limiting of the first toothed disc 42. Two support blocks 410 are fixedly mounted on the side of the torque motor body 2 near the second toothed disc 43. A sliding roller 411 is fixedly mounted between the two support blocks 410. The other end of the first elastic plate 47 passes through the sliding roller 411 and is rotatably mounted on the limiting block 46 between the torque motor body 2 and the first elastic plate 47. A first steering block 48 and a second steering block 49 are fixedly installed on one side of the support block 410. The first steering block 48 and the second steering block 49 are respectively fixedly installed on both sides of the support block 410. The sliding roller 411 serves to limit the first elastic plate 47. The first spring 413 is fixedly installed on the side of the rotating block 416 near the electromagnet 415. The other end of the first spring 413 is fixedly installed on the inner wall of the rectangular through hole 414. The first spring 413 serves to drive the rotating block 416 to elastically reset. There are two first springs 413. A guide rod 412 is slidably installed through the rotating block 416. The two ends of the guide rod 412 are fixedly installed on the inner wall of the rectangular through hole 414. The guide rod 412 serves to balance and guide the rotating block 416.The first spring 413 is nested on the outer surface of the guide rod 412. The electromagnet 415 is installed between the two first springs 413. The second toothed disc 43 is slidably installed in the groove 44. The triangular plates on the first and second toothed discs 42 and 43 are tilted at different angles. The rotating block 416 is installed above the sliding ring 417. The side of the first elastic plate 47 slides against the inclined surfaces of the first and second steering blocks 48 and 49, facilitating locking of the connector after the torque motor body 2 is de-energized. During insertion locking, due to the inertia of the connector, not only is the connector easily damaged, but the output end of the torque motor body 2 is also easily damaged. Because the electromagnet 415 attracts the rotating block 416, after the rotating block 416 is detached from the connector, the first and second toothed discs 42 and 43 cooperate to limit and self-lock, minimizing the need for manual opening of the connector. This improves the device's elastic self-locking capability, extends the service life of the self-locking components, enhances the automaticity of the self-locking mechanism, and improves the user experience.

[0036] Please see Figures 3-4 As shown, a vibration damping assembly 6 is provided on the base 1. The vibration damping assembly 6 includes a mounting groove 67 formed on the side of the base 1 near the mounting bracket 3. A mounting plate 61 is installed in the mounting groove 67. A telescopic rod 63 and a second spring 64 are fixedly installed on the side of the mounting plate 61 away from the torque motor body 2. The telescopic rod 63 supports and stabilizes the mounting plate 61. The other ends of the telescopic rod 63 and the second spring 64 are fixedly installed on the inner bottom wall of the mounting groove 67. The second spring 64 drives the mounting plate 61 to elastically return to its original position. A damper 65 is fixedly installed on the telescopic rod 63. The damper 65 counteracts the return force of the second spring 64, thus buffering and damping the vibration of the mounting plate 61. The second spring 64 is fixedly installed on the side of the mounting plate 61 near the telescopic rod 63. The second elastic plate 62 acts as an elastic buffer against external forces on the mounting plate 61. The other end of the second elastic plate 62 slides against the inner wall of the mounting groove 67. A third elastic plate 66 is rotatably installed between the mounting plate 61 and the inner wall of the mounting groove 67. The third elastic plate 66 counteracts external forces on the mounting plate 61. An elastic band 68 is fixedly installed between the mounting plate 61 and the mounting frame 3. The elastic band 68, in conjunction with the third elastic plate 66, acts to buffer and dampen the mounting plate 61, facilitating vibration damping during the operation of the torque motor body 2. This minimizes damage to the torque motor body 2 caused by vibration, improves the vibration damping effect of the device, enhances the safety and stability of the device, and improves the vibration damping capability of the device.

[0037] Please see Figure 1 , Figure 2 , Figure 5 and Figure 7As shown, a clamping assembly 5 is provided on the mounting plate 61. The clamping assembly 5 includes a slide groove 51 on the side of the mounting plate 61 near the torque motor body 2. Two bidirectional screws 52 are rotatably mounted in the slide groove 51. Moving blocks 53 are threaded through the bidirectional screws 52 near their ends. The bidirectional screws 52 drive the moving blocks 53 to slide in the slide groove 51, causing the moving blocks 53 to drive the clamping plate 55 to clamp the torque motor body 2. The clamping plate 55 is rotatably mounted on the side of the moving blocks 53 near the torque motor body 2. A rotating disk 59 is rotatably mounted on one side of the mounting plate 61. The connecting shaft of the rotating disk 59 slides through the slide groove 51 and is fixedly mounted on the bidirectional screws 52, causing the rotating disk 59 to drive the bidirectional screws 52 to rotate in the slide groove 51. A limiting disk 57 with a limiting hole 58 is fixedly mounted on the side of the mounting plate 61 near the rotating disk 59. The limiting hole 58 is opened on the side of the limiting disk 57 near the rotating disk 59. The rotating disk 59 slides through the limiting disk 57. A limit rod 510 is installed, and a baffle 511 is fixedly installed at the middle position of the end of the limit rod 510 near the limit plate 57. The baffle 511 stabilizes the limit rod 510 and prevents it from slipping. The limit rod 510 is slidably inserted into the limit hole 58, which limits and stabilizes the limit rod 510. A rubber pad 56 is fixedly installed on the side of the clamping plate 55 near the torque motor body 2. The rubber pad 56 provides friction between the torque motor body 2 and the clamping plate 55, minimizing the possibility of the torque motor body 2 slipping during clamping by the clamping plate 55. A support rod 54 is slidably installed on the moving block 53. The two ends of the support rod 54 are fixedly installed in the slide groove 51. The torque motor body 2 is placed on the support rod 54, which facilitates the installation and disassembly of the torque motor body 2, facilitates stable clamping of the torque motor body 2, improves the work efficiency of device installation and disassembly, improves the clamping stability of the device, and improves the clamping and limiting ability of the device.

[0038] The working principle of this invention is as follows: When using the device, first open the sliding ring 417, then place the torque motor body 2 on the support rod 54, so that the sliding ring 417 is engaged and sleeved on the output end of the torque motor body 2. Then, turn the rotating disk 59, so that the rotating disk 59 drives the bidirectional screw 52 to rotate. At the same time, the bidirectional screw 52 drives the two moving blocks 53 to move relative to each other. Simultaneously, the moving blocks 53 drive the clamping plate 55 and the rubber pad 56 to move towards the torque motor body 2 to clamp it. At the same time, the moving blocks 53 slide on the support rod 54. Then, push the limiting rod 510, so that the limiting rod 510 slides and inserts into the rotating disk 59. Inside the limiting hole 58; the external force of the vibration of the torque motor body 2 is squeezed by the mounting plate 61 to compress the telescopic rod 63 and the second spring 64, so that the telescopic rod 63 and the second spring 64 are in a state, and at the same time, the mounting plate 61 squeezes the second elastic plate 62 and the third elastic plate 66, so that the second elastic plate 62 and the third elastic plate 66 are in a compressed state, and at the same time, the second elastic plate 62 slides on the inner bottom wall of the mounting groove 67, and at the same time, the mounting plate 61 stretches the elastic band 68, so that the elastic band 68 is in a stretched state, and at the same time, the damper 65 slowly absorbs the elastic restoring force of the elastic band 68, the second elastic plate 62, the second spring 64 and the damper 65;

[0039] When the torque motor body 2 is de-energized, the electromagnet 415 is powered, causing the electromagnet 415 to attract the rotating block 416 to slide within the rectangular through hole 414. Simultaneously, the rotating block 416 slides on the guide rod 412, compressing the first spring 413, thus putting the first spring 413 into a compressed state. At the same time, the rotating block 416 drives the sliding ring 417 to move downward, causing the sliding ring 417 to drive the first elastic plate 47 to slide on the side of the first steering block 48 and the second steering block 49. Simultaneously, the first elastic plate 47 slides on the sliding roller 411, and the first elastic plate 47 after steering pushes the sliding rod 45 upward through the limiting block 46. Simultaneously, the sliding rod 45 pushes the second toothed disc 43 out of the groove 44, and the second toothed disc 43 moves towards the first toothed disc 42, causing the second toothed disc 43 and the second toothed disc 43 to mesh together, facilitating self-locking and stabilization of the first toothed disc 42.

[0040] 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.
