Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of chain window openers, and relates to the anti-bending structure of the chain of a chain window opener. Background Technology
[0002] Electric window openers are devices that convert electricity into a pushing force to open a window or a pulling force to close it. These electric window openers replace manual operation, enabling windows to open and close automatically and providing great convenience to people's lives. Most chain-type window openers on the market are usually designed with a fixed angle anti-bend feature on only one side of the movable window. During use, the chain may bend and fail to effectively support the weight of the window, causing the window to sway easily under external forces.
[0003] This design features fixed-angle installation at both the front and rear ends, which effectively ensures that the chain does not bend during operation. Utility Model Content
[0004] To solve the implementation technical problems, the present invention adopts the following technical solution:
[0005] A chain anti-bending structure for a chain window opener includes: a window opener housing, a drive assembly, and a chain assembly disposed within the window opener housing;
[0006] The drive assembly includes a drive motor and a gear set driven by the drive motor.
[0007] The chain assembly includes: a chain housing, a chain disposed in the chain housing, and a sprocket;
[0008] The end of the chain box housing extends in an arc to the outlet of the window opener housing. The sprocket is set in the chain box housing. One end of the chain is set in the chain box housing, and the other end passes out from the outlet of the window opener housing. A rotating fixing seat is installed at the end of the chain box housing, and the connection with the window is achieved through the rotating fixing seat.
[0009] The middle section of the chain meshes with the sprocket; the drive motor achieves transmission with the sprocket through a gear set.
[0010] A set of positioning seats is provided at the end of the chain box housing. The positioning seats are located at the outlet of the window opener housing. A straight limiting pipe is formed in the positioning seat and connects to the outlet of the window opener housing. The straight limiting pipe can limit the angle of both ends of the chain.
[0011] As a further embodiment of this utility model, the overall length of the straight limiting pipe is at least twice the chain pitch.
[0012] As a further embodiment of this utility model, an auxiliary limiting seat is also provided on the inner side of the positioning seat.
[0013] As a further embodiment of this utility model, the auxiliary limiting seat is installed at different mating positions with the chain, including: a central limiting seat at the upper end and an outer arc limiting seat at the lower end.
[0014] As a further embodiment of this utility model: the overall length of the outer arc limiting seat and the shaft limiting seat is at least twice the chain pitch.
[0015] As a further embodiment of this utility model, the chain and the support portion of the rotating fixed base are concentrically connected.
[0016] The beneficial effects of this utility model are as follows: by setting a positioning seat structure with a length of twice the chain pitch, the two sides of the chain can be simultaneously limited. At the same time, combined with the inner axis limiting and outer arc limiting structure, the chain will not bend when running back and forth or after unfolding, thus improving the stability of the chain operation.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. It should be understood that this application is not limited to the exemplary embodiments disclosed herein. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0021] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0023] In the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0024] This utility model provides a reference. Figures 1-3 In this embodiment of the utility model, the anti-bending structure of the chain window opener includes: a window opener housing 1 and a drive assembly and a chain 2 assembly disposed in the window opener housing 1;
[0025] The drive assembly includes: a drive motor 9 and a gear set 8 driven by the drive motor 9;
[0026] The chain 2 assembly includes: a chain housing 5, a chain 2 disposed in the chain housing 5, and a sprocket 7;
[0027] The end of the chain box housing 5 extends in an arc shape to the outlet position of the window opener housing 1. The sprocket 7 is set in the chain box housing 5. One end of the chain 2 is set in the chain box housing 5, and the other end passes out from the outlet of the window opener housing 1. The end is equipped with a rotating fixing seat 3. In actual installation, the rotating fixing seat 3 is set on the movable window seat 4 to realize the connection with the window.
[0028] The middle section of chain 2 meshes with sprocket 7, and the working wire of chain 2 is operated through sprocket 7; drive motor 9 is driven by gear set 8 to achieve transmission with sprocket 7. When the window is opening and closing, drive motor 9 drives sprocket 7 to rotate forward or reverse, thereby achieving the working effect of chain 2 being sent out to open the window or chain 2 being retracted to close the window.
[0029] A set of positioning seats 6 is provided at the end of the chain box housing 5. The positioning seats 6 are located at the outlet position of the window opener housing 1. A straight limiting pipe 12 connected to the outlet of the window opener housing 1 is formed in the positioning seat 6. The straight limiting pipe 12 can limit the angle of both ends of the chain 2. The extension direction of the straight limiting pipe 12 is consistent with the outlet direction of the window opener housing 1. When the chain 2 runs back and forth, the chain 2 will not bend.
[0030] Furthermore, the overall length of the straight limiting pipe 12 is at least twice the pitch of the chain 2. Combined with the unidirectional limiting design of the chain 2 plates in the chain 2, it ensures that the chain 2 is delivered at a fixed angle, thus preventing the chain 2 from bending.
[0031] Furthermore, an auxiliary limiting seat is also provided on the inner side of the positioning seat 6, which can work with the straight limiting pipe 12 to limit the direction of the chain 2 when it runs back and forth;
[0032] The auxiliary limiting seat is equipped with different mating positions with the chain 2, including: the outer arc limiting seat 11 at the lower end, which limits the outer arc position of the chain 2; and the shaft limiting seat 10 at the upper end, which limits the shaft position of the chain 2. When the chain 2 runs back and forth, it works in conjunction with the straight limiting pipe 12 to improve the stability of the chain 2.
[0033] Furthermore, the overall length of the outer arc limiting seat 11 and the axial limiting seat 10 is at least twice the chain pitch 2, corresponding and cooperating with the straight limiting pipe 12.
[0034] The chain 2 and the rotating fixed base 3 are concentrically connected, so that the chain 2 and the rotating fixed base 3 can support each other and ensure that the end of the chain 2 can be fixed at an angle.
[0035] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
