Description

Technical Field

[0001] This utility model belongs to the technical field of outdoor sunshade products, and in particular relates to a sliding track structure for venetian blinds. Background Technology

[0002] Venetian blinds are a relatively new type of outdoor structure that can achieve different functions by changing the rotation angle of the slats. Most venetian blinds on the market today are equipped with a drive mechanism that allows the shading fabric to extend or retract as needed to meet people's living needs. The drive mechanism consists of a drive unit and a guide rod that slides along the drive unit. When the drive unit slides along the guide rod, the venetian blinds can be extended or retracted.

[0003] For example, Chinese utility model patent CN219671902U, entitled "Rotary and Telescopic Venetian Awning," discloses a rotatable and telescopic venetian awning, including several uprights, several horizontal base plates, several vertical base plates, and several louvers. The uprights, horizontal base plates, and vertical base plates are fixedly connected, and the horizontal base plates and vertical base plates form a base plate frame. Connecting rods are provided at both ends of the louvers, and the louvers are connected to the base plate frame through the connecting rods. It also includes a louver rotation drive mechanism and a louver movement drive mechanism. The louver rotation drive mechanism includes a main rotation drive assembly, a main transmission rod, and a secondary rotation transmission assembly. In the aforementioned patent, the movement of the louvers is controlled by setting a guide rod inside the horizontal base plate and sliding the guide rod with the offset wheels set on both sides of the louvers. However, since the product's rotary transmission component and main transmission rod are limited and fixed by a hexagonal structure, the force of the motor will be applied to the rotary transmission component during the motor transmission process, causing the rotary transmission component to shift outward, thereby causing the wheels to derail and the main rotary drive component to fall off, which poses a certain safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a sliding track structure for louvered awnings to solve the technical problem that the unstable cooperation between the rotary transmission component and the main transmission rod in the existing sliding track structure of louvered awnings leads to the wheels easily derailing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sliding track structure for a louvered awning, including a crossbeam and a drive unit for driving the louvers to move. The drive unit is provided with pulleys on both sides, and a guide rail assembly is provided inside the crossbeam along the direction of movement of the drive unit. The drive unit and the guide rail assembly are slidably engaged. The guide rail assembly includes a first limiting part for limiting the lateral movement of the drive unit and a second limiting part for limiting the longitudinal movement of the drive unit.

[0006] Preferably, the first limiting part includes a guide rail frame, on which a plurality of guide rails are provided, and side plates are installed between adjacent guide rails. The two sides of the side plates extend upward at an angle to abut against the inner side of the pulley.

[0007] Preferably, a mounting position is formed between adjacent guide rails, and the side plate is fixed to the mounting position by a threaded connection and extends along the length direction of the guide rail.

[0008] Preferably, the guide rail frame is integrally formed on the inner side of the crossbeam.

[0009] Preferably, the second limiting part includes an upper guide part disposed on the inner wall of at least one side of the crossbeam, the upper guide part and the guide rail being disposed correspondingly, and a limiting groove being formed between the upper guide part, the guide rail and the inner wall of the crossbeam.

[0010] Preferably, when the drive unit is movably installed inside the crossbeam, at least one of the pulleys is engaged in the limiting groove, and the outer side of the pulley corresponds to the inner wall of the crossbeam, while the inner side of the pulley corresponds to the baffle.

[0011] Preferably, the upper guide portion includes an extension protruding from the inner wall of the crossbeam and a guide portion located below the extension portion. The end of the guide portion is provided with a guide post, and the guide post and the guide rail are vertically corresponding and extend along the horizontal direction of the guide rail.

[0012] Preferably, the pulley has a groove, and the guide post and guide rail are located at the upper and lower ends of the groove, respectively, and cooperate with the groove for positioning.

[0013] By employing the above technical solution, this utility model, compared with the prior art, has the following beneficial effects: By setting a guide rail assembly that slides within the crossbeam and engages with the drive unit, and integrating a first limiting mechanism and a second limiting mechanism within this guide rail assembly, the lateral movement (left-right offset) and longitudinal movement (up-down disengagement) of the pulley on the drive unit are respectively restricted. This achieves omnidirectional constraint on the pulley in four directions (up, down, left, and right), ensuring it can only move back and forth along the guide rail. This structure significantly enhances the stability of the engagement between the pulley and the guide rail, effectively preventing the drive unit from disengaging from the guide rail, and solves the technical problem of pulley derailment caused by unstable engagement between the rotary transmission assembly and the main transmission rod in existing louvered awnings.

[0014] Specifically, when the drive unit is installed inside the crossbeam, the sliding grooves on its two side pulleys slide against the guide rails, achieving initial positioning and allowing the pulleys to move smoothly along the guide rails. Furthermore, side plates are provided between adjacent guide rails, with both sides of these side plates extending upwards to form baffles, located inside the pulleys on both sides of the drive unit. When the pulleys shift left or right, the baffles abut against the pulleys, thereby constraining the lateral displacement of the pulleys.

[0015] Meanwhile, an upper guide portion is correspondingly provided above at least one side of the guide rail. This upper guide portion cooperates with the guide rail in the vertical direction and extends into the groove of the pulley, forming a longitudinal limit on the pulley and preventing the pulley from detaching from the top of the guide rail. Through the above structure, the pulley is always effectively guided and restricted during operation, ensuring the reliability and safety of the transmission process. Attached Figure Description

[0021] like Figure 1-6 As shown: A sliding track structure for a louvered awning includes a crossbeam 1 and a drive unit 2 for moving the louvers. It should be noted that the outer frame of the louvered awning needs to be composed of four crossbeams. The drive unit 2 is arranged within two crossbeams that allow it to move back and forth, so as to control the opening and closing of the louvers by driving the drive unit. Pulleys 201 are provided on both sides of the drive unit 2. In this embodiment, a rotating shaft is provided at both the front and rear ends of the bottom of the drive unit 2, and pulleys 201 are installed on both sides of the rotating shaft, making the drive unit 2 a four-wheel structure. The four-wheel structure, combined with two guide rails, can increase the stability during the driving process. A guide rail assembly is provided inside the crossbeam 1 along the direction of movement of the drive unit 2. The guide rail assembly provides guidance for the drive unit and also facilitates smoother sliding of the drive unit 2. The drive unit 2 and the guide rail assembly slide together. The guide rail assembly includes a first limiting part for restricting the lateral movement of the drive unit and a second limiting part for restricting the longitudinal movement of the drive unit.

[0022] By setting a guide rail assembly that slides within the crossbeam 1 to engage with the drive unit 2, and integrating a first limiting mechanism and a second limiting mechanism within this guide rail assembly, the lateral movement (left-right offset) and longitudinal movement (up-down disengagement) of the pulley 201 on the drive unit 2 are respectively restricted. This achieves omnidirectional constraint on the pulley 201 in four directions (up, down, left, and right), allowing it to move only along the guide rail. This structure significantly enhances the stability of the engagement between the pulley 201 and the guide rail 102, effectively preventing the drive unit 2 from disengaging from the guide rail 102, and solving the technical problem of pulley derailment caused by unstable engagement between the rotary transmission assembly and the main transmission rod in existing louvered awnings.

[0023] like Figure 1-5 As shown: The first limiting part includes a guide rail frame 101, which serves to support and divide the space. The guide rail frame 101 is provided with several guide rails 102. In this embodiment, two sets of guide rails 102 are provided, respectively arranged on both sides of the guide rail frame 101 and integrally formed with it. Side plates 103 are installed between adjacent guide rails 102. Both sides of the side plates 103 extend upwards at inclined angles, with baffles 104 for abutting against the inner side of the pulley 201. The baffles 104 and the side plates 103 are integrally die-cast. To ensure strength, the side plates 103 can be made of metal, such as steel.

[0024] like Figure 1-5 As shown: A mounting position is formed between adjacent guide rails 102. The guide rail 102 protrudes upward relative to the mounting position, forming a concave state. This state facilitates the installation of the side piece 103, and the size and contour of the mounting position and the side piece 103 are matched. The guide rails 102 on both sides can also limit the side piece 103. The side piece 103 is fixed to the mounting position by a threaded connection and extends along the length of the guide rail 102. The threaded installation makes it easy to replace and remove the side piece 103.

[0025] like Figure 1-3 As shown: The guide rail frame 101 is integrally formed on the inner side of the crossbeam 1. The integral forming method can increase the connection strength between the guide rail frame 101 and the crossbeam 1. At the same time, in order to facilitate the installation of the drive unit 2 and the side piece 103, openings can be made on both sides of the crossbeam 1, and the drive unit 2 and the side piece 103 can be inserted from the openings when installing them.

[0026] In this embodiment, the crossbeam 1 and the guide rail frame 101 can be made of metal materials, specifically aluminum steel, which can increase the overall strength.

[0027] like Figure 2 , Figure 4-5As shown: The second limiting part includes an upper guide part 105 disposed on the inner wall of at least one side of the crossbeam 1, and the upper guide part 105 and the crossbeam 1 are integrally formed. The upper guide part 105 and the guide rail 102 are correspondingly disposed to ensure that they can be properly inserted into the sliding groove to achieve upper and lower limiting. A limiting groove 106 is formed between the upper guide part 105, the guide rail 102 and the inner wall of the crossbeam 1. In this embodiment, the limiting groove 106 is disposed on the right side inside the crossbeam 1. The right wheel of the drive unit 2 can be restricted in the limiting groove 106, thereby increasing the stability during the activity process.

[0028] like Figure 5 As shown: When the drive unit 2 is movably installed in the crossbeam 1, at least one pulley 201 is locked in the limiting groove 106 and the outer side of the pulley 201 corresponds to the inner wall of the crossbeam 1, and the inner side of the pulley 201 corresponds to the baffle 104.

[0029] like Figure 6 As shown: The upper guide portion 105 includes an extension portion 107 protruding from the inner wall of the crossbeam 1 and a guide portion 108 located below the extension portion 107. The upper guide portion 105 is generally L-shaped. The guide portion 108 has a guide post 109 at its end. The guide post 109 and the guide rail 102 are vertically corresponding and extend along the horizontal direction of the guide rail 102. The outer surfaces of the guide post 109 and the guide rail 102 are both arc-shaped surfaces that match the arc-shaped groove 202 of the pulley 201 to reduce friction and facilitate sliding.

[0030] like Figure 2 , 4 As shown in Figure -5: A groove 202 is provided on the pulley 201, and the guide post 109 and the guide rail 102 are located at the upper and lower ends of the groove 202 respectively, and cooperate with the groove 202 to limit movement.

[0031] In summary, when the drive unit 2 of this invention is installed inside the crossbeam 1, the sliding grooves 202 on its two side pulleys 201 form a sliding engagement with the guide rail 102, achieving initial positioning and allowing the pulleys 201 to move smoothly along the guide rail 102. Furthermore, side plates 103 are provided between adjacent guide rails 102, with baffles 104 extending upwards on both sides of the side plates 103, respectively located inside the pulleys 201 on both sides of the drive unit 2. When the pulleys 201 shift left or right, the baffles 104 can abut against the pulleys 201, thereby constraining the lateral displacement of the pulleys 201.

[0032] Meanwhile, an upper guide portion 105 is correspondingly provided above at least one side of the guide rail 102. This upper guide portion 105 cooperates with the guide rail 102 in the vertical direction and extends into the groove 202 of the pulley 201, forming a longitudinal limit on the pulley 202 and preventing the pulley 202 from detaching from the guide rail 102. Through the above structure, the pulley 202 is always effectively guided and restricted during operation, ensuring the reliability and safety of the transmission process.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
