Description

Technical Field

[0001] This utility model belongs to the technical field of motor limit adjustment equipment, specifically relating to a rotating mounting structure for the upper cover of a motor limiter. Background Technology

[0002] Tubular motors are widely used in fields such as automation control and smart homes, and their operational accuracy relies on limit adjustment technology. Currently, there are two main methods for adjusting the upper and lower limits of tubular motors: manual and automatic. Due to the high environmental requirements and cost of automatic adjustment, manual adjustment is currently the dominant method on the market. However, existing manual adjustment methods cannot precisely adjust the limit angle and result in low adjustment efficiency, affecting the user experience. Summary of the Invention

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a rotating mounting structure for the upper cover of a motor limiter.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A rotating mounting structure for a motor limiter cover includes a limiter support body fixedly disposed within a motor housing and a limiter upper seat body located outside the motor housing and rotatably connected to the limiter support body. The upper end of the limiter support body is provided with a limiting ring fixedly disposed inside one end of the motor housing. The lower end of the limiter upper seat body has an upper seat connecting cylinder rotatably disposed circumferentially inside the limiting ring. The lower end of the upper seat connecting cylinder has a connecting component that penetrates the limiter support body and is rotatably connected to the limiter support body via a circumferential rotating connecting assembly. The upper end of the limiter support has a support cylinder that is movably inserted into the inner circumferential side of the upper connecting cylinder. A circumferential elastic limiting component and a circumferential rotation limiting component are respectively provided between the support cylinder and the upper connecting cylinder. The connection stability between the limiter support and the upper limiter body can be ensured by the connecting column and the circumferential rotation limiting component. The rotation angle of the limiter support can be limited by the circumferential elastic limiting component and the circumferential rotation limiting component, and a pre-compression effect can be applied to the limiter support, which makes it easier for the user to control the rotation angle of the limiter support and improves the rotation accuracy.

[0005] In the aforementioned rotating mounting structure of a motor limiter cover, the circumferential rotating connection assembly includes a rotating connection hole that vertically penetrates the limiter support body. The connecting column is coaxially and integrally formed in the center of the inner side of the support cylinder and vertically inserted into the rotating connection hole. The lower end of the connecting column extends to the outer side of the lower end face of the limiter support body, and the lower end of the connecting column is provided with a fixing member that rotates and contacts the lower end face of the limiter support body. The rotating connection hole facilitates the positioning and insertion of the connecting column into the limiter support body, and also facilitates the rotation of the connecting column within the rotating connection hole. Furthermore, the fixing member abuts against the lower end face of the limiter support body, thereby improving the connection stability between the connecting column and the limiter support body.

[0006] In the above-mentioned rotating mounting structure of the motor limiter cover, the fixing member abuts against the lower end face of the limiter support body, and the limiter gasket is connected to the lower end of the connecting column by the connecting bolt. The limiter gasket and the connecting bolt can ensure the connection effect between the connecting column and the limiter support body.

[0007] In the aforementioned rotating mounting structure of a motor limiter cover, the circumferential elastic limiting component includes two symmetrically arranged arc-shaped grooves at the bottom of the upper connecting cylinder. The arc-shaped grooves are circumferentially distributed with the center of the connecting column as the center. The supporting cylinder is provided with two movable limiting columns that are respectively movably inserted into the inner side of the arc-shaped grooves. A preload spring is provided between the corresponding side of the two movable limiting columns and the corresponding end of the arc-shaped grooves. An arc-shaped space is formed between the other side of the movable limiting column and the other end of the arc-shaped groove for the movable limiting column to move. The arc-shaped grooves facilitate the placement of the preload springs, and the arc-shaped space facilitates the movable placement of the movable limiting columns. The arc-shaped space can also limit the movement of the movable limiting columns during rotation. The preload springs can preload the movable limiting columns, which can help users improve the rotation accuracy when rotating the limiter support body.

[0008] In the above-mentioned rotating mounting structure of the motor limiter cover, each arc-shaped groove includes an arc-shaped spring groove located at the bottom of the upper connecting cylinder. At the same end of the corresponding arc-shaped spring groove, an arc-shaped limiting groove is provided. The preload spring is located within the arc-shaped spring groove, and the movable limiting post is movably located inside the arc-shaped limiting groove near the arc-shaped spring groove. One end of the preload spring acts on the movable limiting post, and the other end acts on the end of the arc-shaped spring groove away from the arc-shaped limiting groove. The preload spring can only be located within the arc-shaped spring groove, and the movable limiting post can be movably located within the arc-shaped limiting groove. When the limiter support rotates, one of the movable limiting posts presses against its adjacent preload spring, allowing the user to precisely control the rotation angle. The other movable limiting post is limited by the angle of the arc-shaped limiting groove, and the limiter support can only rotate 15 degrees.

[0009] In the above-mentioned rotating mounting structure of the motor limiter cover, each arc-shaped spring groove is interconnected with the corresponding arc-shaped limiting groove to form the arc-shaped groove. The depth of the arc-shaped spring groove is greater than the depth of the arc-shaped limiting groove. The arc-shaped spring groove can limit the preload spring and ensure the preload effect of the preload spring.

[0010] In the above-mentioned rotating mounting structure of the motor limiter cover, the circumferential rotation limiting component includes a rotating block disposed inside the upper connecting cylinder, the connecting column is disposed at the center of the rotating block, and the supporting cylinder has a limiting groove for the rotating block to be inserted into, and the width of the limiting groove is greater than the width of the rotating block. The rotation angle of the rotating block can be limited by the limiting groove, and the rotation angle of the rotating block in the limiting groove is 15 degrees.

[0011] In the above-mentioned rotating mounting structure of the motor limiter cover, the rotating block includes a first rotating half and a second rotating half that are integrally connected. The first rotating half has an upper seat wire hole located at the bottom of the upper seat connecting cylinder on the side away from the second rotating half, and the second rotating half has an upper seat button hole located at the bottom of the upper seat connecting cylinder on the side away from the first rotating half. The upper seat wire hole facilitates the connection of the power cord to the motor body through the upper seat wire hole, and the upper seat button hole facilitates the connection of the button body to the motor circuit board inside the motor body.

[0012] In the above-mentioned rotating mounting structure of the motor limiter cover, one side of the limiting groove has a support wire hole that penetrates the limiter support body and corresponds to the upper seat wire hole. The support wire hole and the upper seat wire hole can limit and guide the power line, making it easier for the power line to be connected to the motor circuit board inside the motor body.

[0013] In the above-mentioned rotating mounting structure of the motor limiter cover, the wire passage hole of the support body is arc-shaped and its width is greater than the width of the wire passage hole of the upper seat.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. The circumferential elastic limiting component and the circumferential rotation limiting component can limit the rotation angle of the limiter support, making it convenient for users to adjust the rotation and improving the adjustment efficiency.

[0016] 2. The combination of the preloaded spring and the movable limit post makes it easier for users to control the rotation of the limiter support body and improves the adjustment accuracy.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this invention relates to a rotating mounting structure for a motor limiter cover, which is installed within a telescopic track. It includes a limiter support 1 fixedly mounted inside the motor housing and a limiter upper seat 2 located outside the motor housing and rotatably connected to the limiter support 1. The upper end of the limiter support 1 has a limit ring 3 fixedly mounted inside one end of the motor housing, allowing the limiter upper seat 2 to be easily fixedly connected to the motor housing. The lower end of the limiter upper seat 2 has an upper seat connecting cylinder 21 rotatably mounted inside the circumference of the limit ring 3. The lower end of the upper seat connecting cylinder 21 has a connecting component that penetrates the limiter support 1 and is rotatably connected to the limiter support 1 via a circumferential rotating connecting assembly 4. The upper end of the limiter support body 1 has a support cylinder 11 that is movably inserted into the inner side of the upper connecting cylinder 21. A circumferential elastic limiting component 5 and a circumferential rotation limiting component 6 are respectively provided between the support cylinder 11 and the upper connecting cylinder 21. The connection stability between the limiter support body 1 and the upper limiter body 2 can be ensured by the connecting column 211 and the circumferential rotation limiting component 4. The rotation angle of the limiter support body 1 can be limited by the circumferential elastic limiting component 5 and the circumferential rotation limiting component 6, and a pre-compression effect can be applied to the limiter support body 1, which makes it easier for the user to control the rotation angle of the limiter support body 1 and improves the rotation accuracy.

[0027] Specifically, the circumferential rotating connection assembly 4 includes a rotating connection hole 41 that vertically penetrates the limiter support body 1. The connecting column 211 is coaxially and integrally formed on the inner center of the support cylinder 11 and vertically inserted into the rotating connection hole 41. The lower end of the connecting column 211 extends to the outer side of the lower end face 42 of the limiter support body, and the lower end of the connecting column 211 is provided with a fixing member 43 that rotates and contacts the lower end face 42 of the limiter support body. The rotating connection hole 41 facilitates the positioning and insertion of the connecting column 211 into the limiter support body 1, and facilitates the rotation of the connecting column 211 within the rotating connection hole 41. Furthermore, the fixing member 43 abuts against the lower end face 42 of the limiter support body, thereby improving the connection stability between the connecting column 211 and the limiter support body 1.

[0028] The fixing member 43 abuts against the lower end face 42 of the limiter support body, and the limiter 44 is connected to the lower end of the connecting column 211 by the connecting bolt 45. The connection effect between the connecting column 211 and the limiter support body 1 can be guaranteed by the limiter 44 and the connecting bolt 45.

[0029] like Figure 2 , Figure 3 , Figure 5As shown, the circumferential elastic limiting component 5 includes two arc-shaped grooves 51 symmetrically arranged at the bottom of the upper connecting cylinder 21. The arc-shaped grooves 51 are circumferentially distributed with the center of the connecting column 211 as the center. The supporting cylinder 11 is provided with two movable limiting columns 52 that are respectively movably inserted into the inner side of the arc-shaped grooves 51. A preload spring 53 is provided between the corresponding side of the two movable limiting columns 52 and the corresponding end of the arc-shaped grooves 51. An arc-shaped space 54 is formed between the other side of the movable limiting column 52 and the other end of the arc-shaped groove 51 to allow the movable limiting column 52 to move. The arc-shaped grooves 51 facilitate the placement of the preload spring 53, and the arc-shaped space 54 facilitates the movable placement of the movable limiting column 52. The arc-shaped space 54 can play a limiting role during the rotation of the movable limiting column 52. The preload spring 53 can play a preload role on the movable limiting column 52, which can help improve the rotation accuracy when the user rotates the limiting device support body 1.

[0030] Furthermore, each arc-shaped groove 51 includes an arc-shaped spring groove 511 located at the bottom of the upper connecting cylinder 21. At the same end of the arc-shaped spring groove 511, an arc-shaped limiting groove 512 is provided. A preload spring 53 is located within the arc-shaped spring groove 511, and a movable limiting post 52 is movably located on the inner side of the end of the arc-shaped limiting groove 512 closest to the arc-shaped spring groove 511. One end of the preload spring 53 acts on the movable limiting post 52, and the other end acts on the end of the arc-shaped spring groove 511 away from the arc-shaped limiting groove 512. The preload spring 53 can only be located within the arc-shaped spring groove 511, and the movable limiting post 52 can be movably located within the arc-shaped limiting groove 52. When the limiter support 1 rotates, one of the movable limiting posts 52 presses against its adjacent preload spring 53, allowing the user to precisely control the rotation angle. The other movable limiting post 52 is limited by the angle of the arc-shaped limiting groove 512, and the limiter support 1 can only rotate 15 degrees.

[0031] Each arc-shaped spring groove 511 is interconnected with the corresponding arc-shaped limiting groove 512 to form the aforementioned arc-shaped groove 51. The depth of the arc-shaped spring groove 511 is greater than the depth of the arc-shaped limiting groove 512. The arc-shaped spring groove 511 can limit the pre-compression spring 53, thus ensuring the pre-compression effect of the pre-compression spring 53.

[0032] Combination Figure 3 , Figure 5 , Figure 6 As shown, the circumferential rotation limiting assembly 6 includes a rotating block 61 disposed inside the upper connecting cylinder 21, a connecting column 211 disposed at the center of the rotating block 61, and a limiting groove 62 for the rotating block 61 to be inserted into the supporting cylinder 11. The width of the limiting groove 62 is greater than the width of the rotating block 61. The rotation angle of the rotating block 61 can be limited by the limiting groove 62, and the rotation angle of the rotating block 61 in the limiting groove 62 is 15 degrees.

[0033] The rotating block 61 includes a first rotating half 611 and a second rotating half 612 that are integrated into one structure. The integrated structure of the first rotating half 611 and the second rotating half 612 can improve the structural strength and service life. The first rotating half 611 has an upper seat wire hole 212 located at the bottom of the upper seat connecting cylinder 21 on the side away from the second rotating half 612, and the second rotating half 612 has an upper seat button hole 213 located at the bottom of the upper seat connecting cylinder 21 on the side away from the first rotating half 611. The upper seat wire hole 212 facilitates the connection of the power cord to the motor body through the upper seat wire hole 212, and the upper seat button hole 213 facilitates the connection of the button body to the motor circuit board inside the motor body.

[0034] Specifically, the limiting groove 62 has a support wire passage hole 621 on one side that penetrates the limiter support body 1 and corresponds to the upper seat wire passage hole 212. The support wire passage hole 621 and the upper seat wire passage hole 212 can limit and guide the power line, making it easier for the power line to be connected to the motor circuit board inside the motor body.

[0035] Combination Figure 2 , Figure 6 As shown, the cable passage hole 621 of the support body is arc-shaped and its width is greater than that of the cable passage hole 212 of the upper seat, which facilitates the displacement adjustment of the power cable within the cable passage hole 621 of the support body and makes it easier to connect the power cable.

[0036] The principle of this embodiment is as follows: the connection stability between the limiter support 1 and the limiter upper seat 2 can be ensured by the circumferential rotation connection component 4, and the limiter support 1 can be rotated on the limiter upper seat 2. The rotation angle of the limiter support 1 can be limited by the circumferential elastic limit component 5 and the circumferential rotation limit component 6, and the preload spring 53 can preload the limiter support 1, which makes it easier for the user to control the rotation angle of the limiter support 1 and improves the rotation accuracy.
