Description

Technical Field

[0001] This utility model relates to the field of garage door technology, and in particular to a garage door opener track, opener, and garage door system. Background Technology

[0002] In a sliding automatic garage door system, the door opener is used to drive the garage door to open and close. Typically, the door opener is installed on the top of the garage and includes a slider that slides within a track. The slider is connected to the garage door via a connector. The track houses the drive mechanism, including a motor, sprockets, and chains. The forward and reverse rotation of the chain moves the slider along the track, which in turn moves the garage door along a guide groove, thus opening and closing the garage door.

[0003] Because the track of the gate opener needs to provide vertical support for the slider while also providing good linear guidance, the track requires high rigidity and straightness. Typically, a flanged structure B, running along the track length, is installed at the gap A where the track avoids the connecting parts. Figure 6 As shown.

[0004] The aforementioned flange structure enhances the stress balance of the track and prevents the track from bending or twisting. However, the flange structure increases the wear on the slider. Since the door opener is used frequently, the rapid wear of the slider affects the use of the door opener. At the same time, the flange structure at the track segment assembly can easily cause the slider to jam and reduce the user experience. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a garage door opener track, opener, and garage door system, thereby reducing wear on the slider and improving the smoothness of the slider while ensuring that the track shape and function meet the requirements.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A garage door opener track includes:

[0008] substrate;

[0009] Both side plates are located on the same side of the substrate. One side plate is connected to one side of the substrate in the width direction, and the other side plate is connected to one side of the substrate in the width direction.

[0010] Two wing plates are provided, and each side plate is connected to another wing plate along its width direction. The base plate, side plates, and wing plates form a channel. The channel slides with the slider of the door opener. An avoidance opening is formed between the two wing plates. The avoidance opening is used to avoid the connecting piece connected to the slider.

[0011] The contact area between the wing plate and the slider is a plane, and the side plate is provided with an elastic bending structure. The elastic bending structure has the same shape and position in each cross section of the track, and enables the wing plate to provide elastic support force for the slider.

[0012] As a further improvement to the above technical solution:

[0013] The elastic bending structure includes an obtuse-angled bend located in the middle of the width direction of the side plate. The opening of the obtuse angle faces the outside of the side plate. One side of the bend line of the obtuse-angled bend is an outwardly expanding plate. The distance between the two outwardly expanding plates is greater than the dimension of the slider in the corresponding direction. The side plate on the other side of the bend line of the obtuse-angled bend slides with the slider. The included angle between the outwardly expanding plate and the wing plate is α, where 40°≤α≤60°.

[0014] The distance between the bend line and the substrate is L, and the distance between the bend line and the wing plate is M, where 1≤L / M≤3.

[0015] The elastic bending structure includes one or more arc-shaped bending portions, and the side plates on both sides of the arc-shaped bending portions slide in cooperation with the slider;

[0016] It also includes an outwardly expanding arc plate, the edges of which in the width direction are respectively connected to the wing plate and an arc-shaped bend adjacent to the wing plate. The outwardly expanding arc plate protrudes outward from the side plate, the curvature of the outwardly expanding arc plate is greater than the curvature of the arc-shaped bend, and the distance between the two outwardly expanding arc plates is greater than the dimension of the slider in the corresponding direction.

[0017] The width of the outer arc plate in the width direction of the side plate is N, and the width of the side plate is K, where 1 / 4 ≤ N / K ≤ 1 / 2.

[0018] The elastic bending structure includes a first right-angle bending portion and a second right-angle bending portion that are staggered along the width direction of the side plate. An extension portion is formed between the first bending vertex of the first right-angle bending portion and the second bending vertex of the second right-angle bending portion. The extension portion extends outward from the axis away from the track of the side plate. The second right-angle bending portion is connected to the wing plate.

[0019] The side plate between the first bending vertex and the substrate slides in engagement with the slider, while the side plate between the second bending vertex and the wing plate does not contact the slider.

[0020] The distance between the first bending vertex and the substrate is E, and the distance between the second bending vertex and the wing plate is F, where 1≤E / F≤3.

[0021] The base plate, side plate, and wing plate are integrally formed with the elastic bending structure.

[0022] A door opener comprising the garage door opener track described in any of the above descriptions.

[0023] A garage door system, including the aforementioned door opener.

[0024] The beneficial effects of this utility model are as follows:

[0025] This utility model has a compact and reasonable structure and is easy to operate. By setting an elastic bending structure in the middle of the wing plate, the rigidity is improved and the track is prevented from bending or twisting. At the same time, an elastic functional structure is added to the side plate of the plate structure to buffer and disperse the pressure of the slider on the wing plate, thereby improving the strength of the track. While ensuring that the track shape and function meet the requirements, the wing plate with a planar structure supports the slider, reducing wear on the slider and improving the smoothness of the slider.

[0026] This utility model also has the following advantages:

[0027] (1) An obtuse angle bend is provided in the middle of the width direction of the side plate to form an elastic bending structure. This structure is simple and easy to form, and the cross-sectional dimension of the channel is larger than the cross-sectional dimension of the slider. The lower part of both sides of the channel does not contact the slider, reducing the friction between the track and the slider.

[0028] (2) A bending structure with different curvatures is set along the width direction of the side plate to form an elastic bending structure. The curved bending part reduces the friction between the side plate and the slider. The curvature of the outward-expanding arc plate is greater than the curvature of the curved bending part, which increases the cross-section of the channel and makes the lower parts of both sides of the channel not contact the slider, thus reducing the friction between the track and the slider.

[0029] (3) Two right-angle bends are staggered along the width of the side plate to achieve an elastic bending structure and an outward expansion structure on both sides below the track section, thereby improving the overall performance of the track. Attached Figure Description

[0044] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0045] Example 1:

[0046] like Figures 1-5 As shown, the garage door opener track of this embodiment includes a base plate 1, two side plates 2 and two wing plates 3.

[0047] Both side plates 2 are located on the same side of the substrate 1. One side plate 2 is connected to the other side of the substrate 1 along its width direction, and the other side plate 2 is connected to the other side of the substrate 1 along its width direction.

[0048] Two wing plates 3, each side plate 2 is connected to another wing plate 3 along the width direction, the base plate 1, the side plate 2 and the wing plate 3 enclose a channel, the channel slides with the slider 5 of the door opener, and a clearance opening 4 is formed between the two wing plates 3, the clearance opening 4 is used to avoid the connecting parts connected to the slider 5.

[0049] The contact area between the wing plate 3 and the slider 5 is a plane, and the side plate 2 is provided with an elastic bending structure. The elastic bending structure has the same shape and position in each cross section of the track, and enables the wing plate 3 to provide elastic support for the slider 5.

[0050] The cross-section is perpendicular to the track axis, such as... Figure 1 The Z-axis is the length direction of the track. Normally, the connection between the base plate 1 and the side plate 2 is perpendicular. Based on the plate structure, the X-axis is the width direction of the base plate 1, the Y-axis is the width direction of the side plate 2, and the wing plate 3 is parallel to the base plate 1, that is, the width direction of the wing plate 3 is the same as the X-axis direction.

[0051] Normally, the cross-sectional shape of the track is symmetrical, and the wing plate 3 is parallel to the base plate 1.

[0052] The elastic bending structure has the same shape and position in each cross-section of the track, that is, the length direction of the elastic bending structure extends to cover the entire length direction of the wing plate 3, thus playing a reinforcing role.

[0053] In existing technologies, the track structure is as follows: Figure 6 As shown, the tracks are connected at the joint using a sleeve-like connection. The flanged structure B is the main factor causing jamming, and it also causes localized wear on the slider 5, affecting its sliding performance. In this embodiment, the contact area between the wing plate 3 and the slider 5 is planar, which significantly improves the jamming situation and eliminates localized wear, thus extending the service life of the slider 5.

[0054] By setting an elastic bending structure in the middle of the wing plate 3, the rigidity is improved and the track is prevented from bending or twisting. At the same time, an elastic functional structure is added to the side plate 2 of the plate structure to buffer and disperse the pressure of the slider 5 on the wing plate 3, thereby improving the strength of the track. While ensuring that the track shape and function meet the requirements, the wing plate 3 with a planar structure supports the slider 5, reducing the wear on the slider 5 and improving the smoothness of the slider 5.

[0055] Example 2:

[0056] like Figures 1-3 As shown, based on Embodiment 1, the elastic bending structure of the garage door opener track in this embodiment includes an obtuse angle bend located in the middle of the width direction of the side plate 2. The opening of the obtuse angle faces the outside of the side plate 2. One side of the bend line of the obtuse angle bend is an outwardly expanding plate 21. The distance between the two outwardly expanding plates 21 is greater than the dimension of the slider 5 in the corresponding direction. The side plate 2 on the other side of the bend line of the obtuse angle bend is in sliding cooperation with the slider 5. The included angle between the outwardly expanding plate 21 and the wing plate 3 is α, 40°≤α≤60°.

[0057] An obtuse-angle bend is provided in the middle of the width direction of the side plate 2 to form an elastic bending structure. This structure is simple and easy to form, and the cross-sectional dimension of the channel is larger than the cross-sectional dimension of the slider 5. The lower parts of both sides of the channel do not contact the slider 5, reducing the friction between the track and the slider 5.

[0058] like Figure 2 As shown, the distance between the bend line and the base plate 1 is L, and the distance between the bend line and the wing plate 3 is M, where 1 ≤ L / M ≤ 3. The track's profile dimensions and elastic deformation are controlled within a reasonable range.

[0059] like Figure 3As shown, the elastic bending part has an outwardly expanding structure, which can achieve small elastic deformation. Then, after receiving the downward pressure of the slider 5, the wing plate 3 generates a displacement a away from the base plate 1 and a displacement b towards the other wing plate 3.

[0060] Example 3:

[0061] like Figure 4 As shown, based on Embodiment 1, the elastic bending structure of the garage door opener track in this embodiment includes one or more arc-shaped bending parts 22, and the side plates 2 on both sides of the arc-shaped bending parts 22 are slidably engaged with the slider 5.

[0062] It also includes an outwardly expanding arc plate 23, the edges of which in the width direction are connected to the wing plate 3 and an arc-shaped bend 22 adjacent to the wing plate 3 respectively. The outwardly expanding arc plate 23 protrudes outward from the side plate 2, the curvature of the outwardly expanding arc plate 23 is greater than the curvature of the arc-shaped bend 22, and the distance between the two outwardly expanding arc plates 23 is greater than the dimension of the slider 5 in the corresponding direction.

[0063] Specifically, the cross-sections of the arc-shaped bend 22 and the outwardly expanding arc plate 23 are both semi-circular arcs, and the arc-shaped bend 22 protrudes outward from the side plate 2.

[0064] Different curvature bending structures are set along the width direction of the side plate 2 to form an elastic bending structure. The curved bending part 22 reduces the friction between the side plate 2 and the slider 5. The curvature of the outwardly expanding arc plate 23 is greater than that of the curved bending part 22, which increases the cross-section of the channel and prevents the lower parts of both sides of the channel from contacting the slider 5, thereby reducing the friction between the track and the slider 5.

[0065] The elastic bending structure in this embodiment is based on the same principle as the track in Embodiment 1, which increases stiffness and buffers the pressure of the slider 5 borne by the wing plate 3.

[0066] The width of the outwardly expanding arc plate 23 in the width direction of the side plate 2 is N, and the width of the side plate 2 is K, where 1 / 4 ≤ N / K ≤ 1 / 2. The contour dimensions and elastic deformation of the track are controlled within a reasonable range.

[0067] Example 4:

[0068] like Figure 5 As shown, based on Embodiment 1, the elastic bending structure of the garage door opener track in this embodiment includes a first right-angle bending portion and a second right-angle bending portion that are staggered along the width direction of the side plate 2. An extension portion 26 is formed between the first bending vertex 24 of the first right-angle bending portion and the second bending vertex 25 of the second right-angle bending portion. The extension portion 26 extends outward from the axis of the track away from the side plate 2. The second right-angle bending portion is connected to the wing plate 3.

[0069] The side plate 2 between the first bending vertex 24 and the base plate 1 and the slider 5 are in sliding engagement, while the side plate 2 between the second bending vertex 25 and the wing plate 3 and the slider 5 are not in contact.

[0070] Specifically, the connection between the second right-angle bend and the wing plate 3 is at a right angle; the two right-angle bends are staggered, meaning that the openings of the right-angle bends face different directions, with the opening of the first right-angle bend facing the outside of the side plate 2 and the opening of the second right-angle bend facing the inside of the side plate 2; the extension 26 is parallel to the wing plate 3.

[0071] Two right-angle bends are staggered along the width of side plate 2 to achieve an elastic bending structure and an outward expansion structure on both sides below the track section, thereby improving the overall performance of the track.

[0072] The elastic bending structure in this embodiment is based on the same principle as the track in Embodiment 1, which increases stiffness and buffers the pressure of the slider 5 borne by the wing plate 3.

[0073] The distance between the first bending vertex 24 and the base plate 1 is E, and the distance between the second bending vertex 25 and the wing plate 3 is F, where 1 ≤ E / F ≤ 3. The profile dimensions and elastic deformation of the track are controlled within a reasonable range.

[0074] In the above embodiments, the substrate 1, side plate 2, wing plate 3 and elastic bending structure are integrally formed, specifically by roll forming.

[0075] Example 5:

[0076] This embodiment proposes a door opener, including the garage door opener track of any of the above embodiments.

[0077] Example 6:

[0078] This embodiment proposes a garage door system, including the door opener of Embodiment 5.

[0079] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
