Description

Technical Field

[0001] This utility model relates to the field of RV reducer technology, and in particular, it relates to an RV reducer structure with an encoder built in. Background Technology

[0002] With the development of technology, industrial doors are now equipped with electric door openers, which enable electric door opening. A door opener is a device that uses mechanical transmission to open and close the door. Specific types include sliding industrial door openers, wheeled industrial door openers, and roller shutter industrial door openers, with roller shutter industrial door openers being the most commonly used.

[0003] Large industrial gate openers generally suffer from drawbacks such as heavy loads and severe worm gear wear. To ensure that the lifting position of the industrial gate opener does not exceed the upper and lower limits and does not damage the bottom beam or door frame, the requirements for travel limit are becoming increasingly stringent. The internal structure of current industrial gate openers has become relatively mature, so most of them use external mechanical limiters to limit the travel of the industrial gate opener. However, this has the disadvantage of a large amount of mechanical connection structure being exposed to the outside, making it susceptible to oxidation and corrosion from air and water. This not only results in poor safety, but also requires pulling out the positioning plate when adjusting the travel gear position, which is inconvenient to operate. It also leads to the complex structure, high cost, and large size of the entire limiter part.

[0004] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient encoder-integrated RV reducer structure. Utility Model Content

[0005] The purpose of this utility model is to provide an RV reducer structure with an encoder built-in. A mounting part is added to the side of the reducer body, and an absolute encoder is installed in the mounting part to electronically limit the output shaft of the door opener. The electronic limit has high accuracy, is easy to debug, and the built-in encoder has high safety. Furthermore, it does not require structural modification of the entire reducer body and has low installation cost.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

The mounting part is provided with a mounting cavity communicating with the output shaft cylinder, and at least a portion of the encoder is located in the mounting cavity. The encoder is provided with a mounting bracket for connecting to the output shaft cylinder.

[0008] As a preferred embodiment of the present invention, the mounting portion includes an annular ring and a base plate disposed at one end of the annular ring away from the reducer body, such that the annular ring and the base plate form a mounting cavity.

[0026] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0027] Techniques, methods, and systems known to a person skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the license specification.

[0028] Example 1: As Figures 1 to 3The illustration shows only one embodiment of the present invention. An RV reducer structure with an encoder built-in includes a reducer body 3 and a mounting part 1 disposed on the reducer body 3. An output shaft cylinder 31 is disposed on the reducer body 3. An encoder 2 is disposed on the side of the mounting part 1 near the reducer body 3, located at the end of the output shaft cylinder 31. The mounting part 1 is provided with a mounting cavity communicating with the output shaft cylinder 31. At least a portion of the encoder 2 is located in the mounting cavity. The encoder 2 is provided with a mounting bracket 4 for connecting to the output shaft cylinder 31.

[0029] In this utility model, the reducer door motor directly adopts a conventional RV reducer. Since the output shaft of the RV reducer passes through the reducer body 3, the mounting part 1 is installed on the side of the reducer body 3. The encoder 2 is an absolute encoder, which is set on the mounting part 1. The rotating shaft 21 of the encoder 2 is coaxially connected to the output shaft on the reducer body 3. The rotation of the output shaft is recorded by the absolute encoder. After obtaining the upper and lower limits of the roller shutter door lifting, the two readings of the absolute encoder are limited so that when the output shaft rotates, the absolute encoder reading must be between the two limited readings. Once the limited number is reached, the absolute encoder stops rotating (stops unidirectional rotation in this direction) to limit the output shaft.

[0030] It should be noted that the mounting part 1 can be installed on both sides of the reducer body 3. If the RV reducer is mounted on the left side, the output shaft is inserted into the output shaft cylinder 31 from the right side of the reducer body 3, and the mounting part 1 is located on the left side of the reducer body 3. The encoder 2 is coaxially connected to the left end of the output shaft. Conversely, if the RV reducer is mounted on the right side, the output shaft is inserted into the output shaft cylinder 31 from the left side of the reducer body 3, and the mounting part 1 is located on the right side of the reducer body 3. The encoder 2 is coaxially connected to the right end of the output shaft.

[0031] The mounting part 1 is provided with a mounting cavity communicating with the output shaft cylinder 31, and at least a portion of the encoder 2 is located in the mounting cavity. The mounting part 1 includes an annular ring 11 and a base plate 12 disposed at the end of the annular ring 11 away from the reducer body 3, so that the annular ring 11 and the base plate 12 form a mounting cavity. That is, the mounting cavity is a cylindrical cavity structure that extends toward the output shaft cylinder 31. The encoder 2 is disposed in the mounting cavity and then connected to the output shaft.

[0032] The mounting part 1 covers the encoder 2, and at least a portion of the encoder 2 is located inside the mounting cavity, thus completing the "built-in" installation of the encoder 2.

[0033] Furthermore, the encoder 2 is provided with a mounting bracket 4 for connecting to the output shaft cylinder 31; the mounting bracket 4 includes an outer mounting bracket 41 for connecting the encoder 2 and the outer side wall of the output shaft cylinder 31 and an inner mounting bracket 42 for connecting the encoder shaft of the encoder 2 and the inner side wall of the output shaft cylinder 31.

[0034] The outer mounting bracket 41 is a fixed part, which is equivalent to fixing the outer edge (smooth cylinder) of the output shaft cylinder 31 to the main body of the reducer 3 to the main structure of the encoder 2. When the output shaft cylinder 31 rotates with the output shaft, the outer mounting bracket 41 will not rotate. The outer mounting bracket 41 can also limit the outer edge of the output shaft cylinder 31. The inner mounting bracket 41 is a rotating part. The inner mounting bracket 41 is installed on the encoder shaft of the encoder 2. After the output shaft is inserted into the output shaft cylinder 31, it is inserted all the way to the inner mounting bracket 41, so that the encoder shaft rotates synchronously with the output shaft. The encoder electronically limits the rotation of the output shaft.

[0035] This allows for the built-in installation of the encoder without altering the RV reducer's body structure, effectively limiting the output shaft's rotation in two directions. The encoder 2's overall structure is built-in, eliminating the need for exposed mechanical connection structures, making installation convenient, adjustment easy, and providing high electronic limit accuracy, resulting in more stable operation of the external rolling door motor.

[0036] This utility model discloses an RV reducer structure with an encoder built-in. A mounting part is added to the side of the reducer body, and an absolute encoder is installed in the mounting part to electronically limit the output shaft of the door opener. The electronic limit has high accuracy and is easy to debug. The encoder is built-in, which has high safety and does not require structural modification of the entire reducer body, resulting in low installation cost.

[0037] Example 2, still as Figures 1 to 3 The illustration shown is only one embodiment of this utility model. Based on Embodiment 1, in the RV reducer structure built into the encoder of this utility model, an annular ring 11 is provided with an annular wing plate 13 at one end near the reducer body 3. The annular wing plate 13 is provided with fixing bolts for easy connection with the reducer body 3 and bolt holes 14 for easy installation of the fixing bolts. The annular wing plate 13 extends towards the outer edge of the annular ring 11, so that the annular wing plate 13 forms an annular plate structure, and the inner diameter of the annular plate is equal to the outer diameter of the annular ring 11.

[0038] Of course, the number of bolt holes 14 is at least one.

[0039] Finally, the annular ring 11 is provided with an inspection port and a sealing valve 15 for closing the inspection port; the encoder 2 can be inspected when the sealing valve 15 is unscrewed.

[0040] Example 3, still as Figures 1 to 3 As shown, this is only one embodiment of the present invention. Based on any of the above embodiments, in the RV reducer structure built into the encoder of the present invention, the inner side wall of the output shaft cylinder 31 is provided with a first connecting slot 32 for connecting with the output shaft; the inner side of the inner mounting bracket 42 is provided with a second connecting slot 43 for connecting with the output shaft; in fact, the output shaft is a cylindrical roller with a protruding post on the side, which can be inserted into the first connecting slot 32 and the second connecting slot 43, so as to rotate synchronously with the output shaft cylinder 31 and the encoder shaft.

[0041] Furthermore, the surfaces of the mounting part 1 and the mounting bracket 4 are coated with a waterproof layer to prevent water from entering the encoder 2.

[0042] Of course, the reducer body 3 is provided with a drive shaft 33 connected to the output shaft cylinder 31, and the drive shaft 33 of the RV reducer is arranged perpendicular to the output shaft.

[0043] Finally, the mounting part 1 is a one-piece molded part. In fact, the annular ring 11, the base plate 12 and the annular wing plate 13 are one-piece molded parts, which ensures the structural stability of the mounting part 1, the structural strength of the mounting part is higher and the service life is longer.

[0044] This utility model discloses an RV reducer structure with an encoder built-in. A mounting part is added to the side of the reducer body, and an absolute encoder is installed in the mounting part to electronically limit the output shaft of the door opener. The electronic limit has high accuracy and is easy to debug. The encoder is built-in, which has high safety and does not require structural modification of the entire reducer body, resulting in low installation cost.

[0045] This utility model is not limited to the specific embodiments described above, and various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made to the above embodiments based on the technical essence of this utility model should be included within the protection scope of this utility model.
