DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0031] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The embodiment of the present application provides a retractable folding rain shielding device, including a folding assembly and a flexible shielding portion. Along the first direction, two folding assemblies are provided, and the two folding assemblies are arranged at intervals. The folding assembly includes a support portion 1, a moving portion 11 and a folding component 2. The moving portion 11 is movably provided on the support portion 1 along the second direction. The folding component 2 includes a first connecting portion 3 and a second connecting portion 4. The first connecting portion 3 is rotatably connected to the support portion 1, the second connecting portion 4 is rotatably connected to the moving portion 11, and the first connecting portion 3 is rotatably connected to the middle of the second connecting portion 4. The flexible shielding portion is opened by the two folding components 2.

[0033] The first direction may be the direction shown by the X axis in the figure, and the first direction may be parallel to the horizontal direction. The second direction may be the direction shown by the Z axis in the figure, and the second direction may be parallel to the vertical direction.

[0034] Two folding components are provided so that the two folding components can open the flexible shielding part. The two folding components are arranged at intervals so that the length of the flexible shielding part between the two folding components can be adjusted as needed.

[0035] The middle portion of the second connecting portion 4 refers to a point between both ends of the second connecting portion 4 .

[0036] In the embodiment where the second direction is a vertical direction, the moving portion 11 may be disposed below the connection between the first connecting portion 3 and the supporting portion 1 .

[0037] The centers of the rotation axis 15 of the first connection part 3 and the second connection part 4 are parallel, and the center of the rotation axis 15 of the first connection part 3 may be parallel to the horizontal direction.

[0038] When the movable portion 11 moves relative to the supporting portion 1, the angle between the first connecting portion 3 and the second connecting portion 4 can change. For example, when the movable portion 11 moves in a direction away from the first connecting portion 3, the movable portion 11 drives the second connecting portion 4 to rotate in a direction closing with the first connecting portion 3. At the same time, driven by the second connecting portion 4, the first connecting portion 3 rotates in a direction approaching the supporting portion 1. At this time, the folding component 2 switches to a retracted state.

[0039] When the moving part 11 moves toward the direction approaching the first connecting part 3, the moving part 11 drives the second connecting part 4 to move toward the direction away from the first connecting part 3. At the same time, driven by the second connecting part 4, the first connecting part 3 rotates toward the direction away from the supporting part 1. At this time, the folding part 2 switches to the unfolded state.

[0040] The folding component 2 includes a storage state and an unfolded state, so that the rain shielding device of the embodiment of the present application has the advantages of being easy to store and quick to unfold.

[0041] The flexible shielding part is a rain shielding part, that is, when the folding part 2 is in the unfolded state, the flexible shielding part is driven to unfold to shield from rain, and when the folding part 2 is in the retracted state, the flexible shielding part is driven to fold.

[0042] In the embodiment where the second direction is a vertical direction, the flexible shielding portion may cover the top surface of the folding component 2 .

[0043] The flexible shielding part can be made of materials from existing products, and its structure is well known to those skilled in the art, so it will not be described in detail here.

[0044] The flexible shielding part is supported by the folding component 2. When the flexible shielding part is unfolded, a concave structure is formed between adjacent connecting parts. The flexible shielding part forms a depression in the concave space, which is convenient for rainwater to be concentrated in the depression and can be discharged from both sides of the flexible shielding part along the first direction, thereby reducing the risk of rainwater wetting the shielded material.

[0045] See also Figure 5 and Figure 6 In some embodiments, a connector 14 may be provided between the two folding parts 2. On the one hand, the connector 14 can support the flexible shielding part, and on the other hand, the connector 14 connects the two folding parts 2 so that the distance between the two folding parts 2 can be fixed.

[0046] The connecting member 14 may include a rod body 18 , the rod body 18 is provided with a threaded rod 17 , the folding component 2 is provided with a threaded hole, the threaded rod 17 and the threaded hole are threadedly connected, so that the two folding components 2 can be connected by rotating the rod body 18 .

[0047] The number of the connecting members 14 may correspond to the number of the connecting parts, that is, a connecting member 14 is disposed between two adjacent first connecting parts 3 , and a connecting member 14 is also disposed between two adjacent second connecting parts 4 .

[0048] See also Figure 2 In some embodiments, the folding part 2 also includes a third connection part 5 and a fourth connection part 6, and the third connection part 5 is rotatably connected to the first connection part 3. For example, the connection between the third connection part 5 and the first connection part 3 can be located between the connection between the support part 1 and the first connection part 3 and the connection between the second connection part 4 and the first connection part 3, and the fourth connection part 6 is rotatably connected to the third connection part 5 and the second connection part 4, so that the first connection part 3, the second connection part 4, the third connection part 5 and the fourth connection part 6 form a planar four-bar structure.

[0049] The centers of the rotation axes 15 of the third connection portion 5 and the fourth connection portion 6 are parallel to the center of the rotation axis 15 of the first connection portion 3 .

[0050] The planar four-bar linkage structure formed by the first connecting part 3, the second connecting part 4, the third connecting part 5 and the fourth connecting part 6 means that the first connecting part 3, the second connecting part 4, the third connecting part 5 and the fourth connecting part 6 form a parallelogram planar four-bar linkage structure, in which the third connecting part 5 and the second connecting part 4 form two parallel bars, and the first connecting part 3 and the fourth connecting part 6 form two parallel bars. The planar four-bar linkage structure enables the first connecting part 3, the third connecting part 5 and the fourth connecting part 6 to rotate together when the moving part 11 drives the second connecting part 4 to rotate.

[0051] For example, when the movable part 11 moves in a direction away from the first connecting part 3, the second connecting part 4 and the third connecting part 5 move closer to the first connecting part 3. At the same time, driven by the second connecting part 4, the first connecting part 3 and the fourth connecting part 6 move closer to the supporting part 1, so that the folding part 2 can be switched to the storage state.

[0052] On the contrary, when the movable part 11 moves toward the direction approaching the first connecting part 3, the first connecting part 3 moves toward the direction away from the supporting part 1, and the second connecting part 4 and the third connecting part 5 also move toward the direction away from the supporting part 1. Driven by the second connecting part 4 and the third connecting part 5, the fourth connecting part 6 also moves toward the direction away from the supporting part 1, so that the folding part 2 can be switched to the unfolded state.

[0053] The first connecting part 3, the second connecting part 4, the third connecting part 5 and the fourth connecting part 6 form a planar four-link structure, which not only increases the supporting effect of the folding part 2 on the flexible shielding part when the folding part 2 is unfolded, but also increases the unfolding length of the folding part 2 and the shielding area of ​​the flexible shielding part.

[0054] See also Figure 2In some embodiments, the folding member 2 further includes a fifth connection portion 7 and a sixth connection portion 10. The fifth connection portion 7 is rotatably connected to the second connection portion 4. For example, the connection of the fifth connection portion 7 to the second connection portion 4 may be located between the connection of the fourth connection portion 6 to the second connection portion 4 and the connection of the first connection portion 3 to the second connection portion 4. The sixth connection portion 10 is rotatably connected to the fourth connection portion 6 and the fifth connection portion 7. For example, the connection of the second connection portion 4 to the fourth connection portion 6 may be located between the connection of the third connection portion 5 to the fourth connection portion 6 and the connection of the sixth connection portion 10 to the fourth connection portion 6, so that the second connection portion 4, the fourth connection portion 6, the fifth connection portion 7 and the sixth connection portion 10 form a planar four-bar linkage structure.

[0055] The centers of the rotation axes 15 of the fifth connection portion 7 and the sixth connection portion 10 are parallel to the center of the rotation axis 15 of the first connection portion 3 .

[0056] The second connecting part 4, the fourth connecting part 6, the fifth connecting part 7 and the sixth connecting part 10 form a planar four-bar linkage structure, which means that the second connecting part 4, the fourth connecting part 6, the fifth connecting part 7 and the sixth connecting part 10 form a parallelogram planar four-bar linkage structure, in which the second connecting part 4 and the sixth connecting part 10 form two parallel bars, and the fourth connecting part 6 and the fifth connecting part 7 form two parallel bars. The planar four-bar linkage structure enables the first connecting part 3, the third connecting part 5, the fourth connecting part 6, the fifth connecting part 7 and the sixth connecting part 10 to rotate together when the moving part 11 drives the second connecting part 4 to rotate.

[0057] For example, when the movable part 11 moves in a direction away from the first connecting part 3, the second connecting part 4 and the third connecting part 5 move closer to the first connecting part 3. At the same time, driven by the second connecting part 4, the first connecting part 3, the fourth connecting part 6 and the fifth connecting part 7 move closer to the supporting part 1. Driven by the fourth connecting part 6, the sixth connecting part 10 moves closer to the second connecting part 4, so that the folding part 2 can be switched to the storage state.

[0058] On the contrary, when the movable part 11 moves toward the direction approaching the first connecting part 3, the first connecting part 3 moves toward the direction away from the supporting part 1, and the second connecting part 4 and the third connecting part 5 also move toward the direction away from the supporting part 1. Driven by the second connecting part 4 and the third connecting part 5, the fourth connecting part 6 and the fifth connecting part 7 also move toward the direction away from the supporting part 1. Under the action of the fourth connecting part 6, the sixth connecting part 10 moves toward the direction away from the supporting part 1, so that the folding part 2 can be switched to the unfolded state.

[0059] The second connecting part 4, the fourth connecting part 6, the fifth connecting part 7 and the sixth connecting part 10 form a planar four-bar structure, which further increases the supporting effect of the flexible shielding part when the folding part 2 is unfolded, and further increases the unfolding length of the folding part 2, thereby increasing the shielding area of ​​the flexible shielding part.

[0060] See also Figure 2 In some embodiments, the sixth connection part 10 includes a first segment 8 and a second segment 9 connected in sequence, the fourth connection part 6 and the fifth connection part 7 are respectively rotatably connected to the first segment 8, and the second segment 9 is arranged on the side of the fourth connection part 6 away from the fifth connection part 7.

[0061] The second segment 9 is arranged on the side of the fourth connection part 6 away from the fifth connection part 7, so that the length of the sixth connection part 10 is greater than the distance between the connection point of the fourth connection part 6 at the sixth connection part 10 and the connection point of the fifth connection part 7 at the sixth connection part 10, and the sixth connection part 10 is partially arranged on the side of the fourth connection part 6 away from the fifth connection part 7.

[0062] In the embodiment where the movable portion 11 is arranged below the connection between the first connecting portion 3 and the supporting portion 1, such an arrangement allows the side of the second segment 9 away from the first segment 8 to be in a tilted state when the movable portion 11 moves toward the supporting portion 1, thereby reducing the risk of rainwater dripping from the side of the second segment 9 away from the first segment 8, thereby reducing the risk of the material being wetted by rainwater.

[0063] In some embodiments, the moving portion 11 is sleeved on the supporting portion 1 .

[0064] The movable part 11 is sleeved on the support part 1, so that the movable part 11 can be movably connected to the support part 1 along the first direction. In addition, the movable part 11 is sleeved on the support part 1 to increase the connection strength between the movable part 11 and the support part 1, and reduce the risk of the movable part 11 falling off from the support part 1.

[0065] See also Figure 7 and Figure 8 In some embodiments, the moving part 11 includes a first semi-ring body 27 and a second semi-ring body 21, the two semi-ring bodies are detachably connected, and recessed parts 20 are respectively provided on opposite sides of the two semi-ring bodies.

[0066] When the two recessed portions 20 of the semi-ring bodies are closed, the two recessed portions 20 can form a channel structure for the support portion 1 to pass through.

[0067] The two half rings are detachably connected so that they can be separated or closed, which facilitates the disassembly and assembly of the moving part 11 .

[0068] See also Figure 8 and Fig. 9In some embodiments, the driving part 16 is further included, and the driving part 16 includes two sprockets 23 and a chain 22. The two sprockets 23 are arranged at intervals on the supporting part 1 along the second direction. The chain 22 is wound around the two sprockets 23, the sprockets 23 and the chain 22 are meshed, and the moving part 11 is connected to the chain 22.

[0069] The driving component 16 is used to drive the moving part 11 to move along the second direction.

[0070] Specifically, when the two sprockets 23 rotate, the chain 22 moves driven by the sprockets 23 , and the moving part 11 is connected to the chain 22 , so that the moving part 11 can move driven by the chain 22 .

[0071] The chain 22 and the sprocket 23 cooperate to drive the moving part 11 to move, which has the following advantages: on the one hand, the sprocket 23 and the sprocket 23 cooperate to have high transmission efficiency, and due to the meshing of the sprocket 23 and the chain 22, the risk of relative sliding between the sprocket 23 and the chain 22 is low. On the other hand, the sprocket 23 and the chain 22 are both national standard parts, and the cost is low.

[0072] See also Fig. 9 In some embodiments, the driving component 16 further includes a motor 12, and an output end of the motor 12 is drivingly connected to a sprocket 23 to drive the sprocket 23 to rotate.

The structure and working principle of the reducer are well known to those skilled in the art and will not be described in detail here.

[0074] In this embodiment, the reducer may be a worm gear reducer 13, so that the driving component 16 has a self-locking function, that is, when the motor 12 stops rotating, the sprocket 23 can be locked under the self-locking effect of the worm gear.

[0075] In some embodiments, the driving component 16 may also include a cylinder, a hydraulic cylinder or an electric push rod, the fixed end of the cylinder, hydraulic cylinder or electric push rod is connected to the supporting part 1, and the telescopic end of the cylinder, hydraulic cylinder or electric push rod is connected to the moving part 11 to drive the moving part 11 to move.

[0077] In some embodiments, the driving component 16 may also include two pulleys and a transmission belt. The two pulleys are arranged at intervals on the support part 1 along the second direction. The two pulleys are rotatably connected to the support part 1. The transmission belt is wrapped around the outer peripheral walls of the two pulleys. When the pulleys rotate, the pulleys drive the transmission belt to move, connecting the moving part 11 to the transmission belt, so that the transmission belt can drive the moving part 11 to move.

[0078] In this embodiment, the transmission belt may be a synchronous belt, and correspondingly, the pulley may be a synchronous pulley.

[0079] See also Figure 7 In some embodiments, the moving portion 11 is provided with two abutting portions 28 , and the two abutting portions 28 are spaced apart along a third direction, the third direction is perpendicular to the first direction, and the chain 22 is partially accommodated between the two abutting portions 28 .

[0080] The third direction may be the direction indicated by the Y axis in the figure.

[0081] The two abutting portions 28 are used to limit the chain 22, which can keep the chain 22 appropriately tight so that the sprocket 23 and the chain 22 can remain engaged. On the other hand, the shaking amplitude of the chain 22 during movement is reduced, thereby improving the stability of the chain 22 driving the moving part 11 to move.

[0082] See also Figure 7 In some embodiments, the moving part 11 is further provided with a fixing part 19 , and the fixing part 19 is provided with a plurality of bolts, and the bolts are threadedly connected with the chain 22 .
