Description

Technical Field

[0001] This invention belongs to the field of sunshade technology, and in particular relates to a retractable outdoor sunshade device. Background Technology

[0002] Sunshade equipment is a type of equipment used for temporary or fixed locations to provide shade. Sunshades are typically designed and manufactured to specific specifications for different purposes. Currently, the roof frame of sunshades generally uses an integral structure, which determines the maximum shading area of ​​the completed sunshade. Furthermore, sunshades cannot flexibly adapt to environmental changes, posing potential safety hazards during use.

[0003] Retractable outdoor sunshade equipment, such as awnings and parasols, are widely used in outdoor places such as courtyards, terraces, and parks due to their convenience and flexibility, providing users with a comfortable shady environment.

[0004] However, in practical applications of existing technologies, these types of sunshade devices generally have a significant drawback: they are easily contaminated by environmental debris, which affects their normal use and lifespan. When the device is placed under trees or in natural environments, its unfolded shading surface (such as a tarpaulin or umbrella) inevitably becomes a receiving surface for fallen leaves, dead branches, bird droppings, dust, and other debris. When the user needs to retract the device, the telescopic mechanism (such as a retractable tube or folding arm) will roll up or carry these attached debris into the device's internal storage space during the retraction process.

[0005] Based on this, the present invention designs a retractable outdoor sunshade device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a retractable outdoor sunshade device in order to solve the problems mentioned in the background art.

The second elastic component is sleeved on the outside of the first support rod.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. This invention employs a sliding frame, self-locking moving wheels, tarpaulin, striking rod, linear bearing, second elastic component, pressure plate, air storage frame, air cylinder, circular plate, gear, rack, and extrusion wheel. A simple pressing action triggers a series of precise internal linkage mechanisms, ultimately driving the striking rod to deliver a high-frequency, powerful impact vibration to the tarpaulin. This "one-button" triggering method quickly shakes off leaves, dust, water, and other debris adhering to the tarpaulin surface. The entire process requires no manual patting or climbing for cleaning, making operation extremely convenient and labor-saving. It completely solves the problems of difficult cleaning and poor user experience associated with traditional sunshade equipment, protecting the equipment from the source, significantly extending its service life, and reducing the failure rate. This invention can proactively remove debris before the sunshade equipment is retracted or during use, effectively preventing leaves, branches, and other debris from being rolled up during the equipment's extension and retraction. By incorporating the equipment into tracks, frames, or storage mechanisms, this not only prevents the tarpaulin from being scratched or torn by hard debris, but also eliminates malfunctions such as wear and deformation of moving parts or motor overload caused by debris jamming. Through proactive prevention, this invention significantly reduces the maintenance frequency and repair costs of the equipment, thereby effectively extending its overall service life and ensuring the reliability and synchronicity of the cleaning action. Through the ingenious design of air storage frames, air cylinders, and connecting ropes, this invention achieves the synchronous action of multiple striking units. When the user operates one main control plate, other plates can be driven synchronously through gas pressure or mechanical connecting ropes, thereby ensuring that multiple striking rods distributed in different areas of the tarpaulin can work in a coordinated manner. This design ensures the uniform distribution of striking force, avoiding cleaning dead spots or tarpaulin damage caused by uneven force at a single point, making the cleaning effect more comprehensive and thorough, and ensuring stable and reliable operation of the mechanism.

[0029] 2. In this invention, a pressure plate, air outlet pipe, air jet head, air storage frame, and first elastic component are used. After the leaves and debris attached to the tarpaulin are initially loosened by tapping and vibration, the high-speed airflow from the air jet head powerfully blows these loosened debris off the tarpaulin surface. This synergistic effect of "vibration followed by blowing" overcomes the limitations of a single cleaning method and can effectively remove debris of different sizes and degrees of adhesion, ensuring a more thorough and clean cleaning effect. It pioneers a "tension + loosening" dual-stage cleaning mode, achieving full-cycle coverage without dead angles. One of the core advantages of this invention is that its cleaning function is perfectly synchronized with the equipment's usage status, forming a unique dual-stage cleaning mechanism: Cleaning in the unfolded state: When the equipment is in the unfolded state... In the slack-out state, when the tarpaulin is taut, users can actively trigger the pneumatic system to clean the taut immediately, preventing debris from accumulating and compacting over time, and maintaining the tarpaulin's cleanliness and appearance. Cleaning in the retracted state: During the retraction and storage process, the sliding frames automatically press against the pressure plate, triggering the pneumatic system to blow air through the loosely folded tarpaulin. This step is crucial, effectively removing any debris that may have been caught or trapped during folding, eliminating the risk of debris entering the equipment. This "active cleaning when taut, automatic cleaning when loose" mode ensures effective cleaning throughout the entire lifespan of the equipment, whether unfolded or retracted, achieving true full-cycle, comprehensive maintenance.

[0030] 3. In this invention, an air storage frame, a moving plate, a pressure plate, and a first elastic component are used. When the user operates the equipment to retract, and adjacent sliding frames approach each other, the system is triggered first. The sliding frames squeeze the pressure plate, compressing the gas in the air storage frame to form a cushioning effect similar to an "air cushion." At the same time, the first elastic component undergoes elastic deformation, absorbing the impact kinetic energy. This dual buffering mechanism significantly reduces the closing speed and impact force of the sliding frames, fundamentally eliminating the safety hazard of pinching the user's fingers at the moment of closure. This elevates the safety of the equipment to a new level, ensuring the stability and reliability of the equipment operation. This buffering system not only protects the user but also the equipment itself. By absorbing and mitigating the mechanical impact of the sliding frames at the end of retraction, it avoids the instantaneous stress caused by rigid collisions on the sliding frames, guide rails, and other connecting components, effectively preventing component deformation, wear, or even damage. This makes the entire retraction process smoother and more stable, without jamming or impact, significantly improving the operational reliability and service life of the equipment.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see the appendix Figure 1 -Appendix Figure 9 This invention provides a technical solution: a retractable outdoor sunshade device, including a canopy 3 and a sliding frame 1. The canopy 3 is installed on the sliding frame 1. Two self-locking moving wheels 2 are installed at the bottom of the sliding frame 1. A support rod 4 is installed inside the sliding frame 1. Two first support rods 5 and two second support rods 6 are installed between the support rods 4 and the sliding frame 1. Two holding and buffering mechanisms 11 are installed on the side of the sliding frame 1. A middle tube 12 is connected to the outside of the holding and buffering mechanism 11. The other end of the middle tube 12 is connected to a lateral moving mechanism 13. The lateral moving mechanism 13 is installed on the side of the second support rod 6. A rotating pressing mechanism 14 is provided outside the lateral moving mechanism 13. The rotating pressing mechanism 14 is installed on the side of the second support rod 6. A movable striking mechanism 15 is provided on the lower surface of the rotating pressing mechanism 14. The movable striking mechanism 15 is slidably connected to the outside of the first support rod 5. A connecting rope 16 is connected between the front holding and buffering mechanisms 11.

[0044] The device uses a sliding frame 1 and self-locking casters 2. The self-locking casters facilitate the movement and locking of the entire sunshade device. The sliding frame 1 supports the tarpaulin 3, making it easy to unfold and retract the entire sunshade device.

[0045] Specifically, such as Figures 1-4 As shown, there are several sliding frames 1. The support rod 4 is slidably connected to two first connecting sleeves 7. The two first connecting sleeves 7 are hinged to a first rotating link 8. The two first rotating links 8 between the two sliding frames 1 are arranged in a cross pattern and are hinged to each other.

[0046] The sliding frame 1 has two second connecting sleeves 10 that are slidably connected to it. The sliding frame 1 is also hinged to a second rotating link 9, which is hinged to the second connecting sleeve 10 on the outside of the adjacent sliding frame 1.

[0047] The first connecting sleeve 7, the second connecting sleeve 10, the first rotating link 8 and the second rotating link 9 are used to connect adjacent sliding frames 1, and to connect and guide the two to approach each other, so as to ensure stable mutual approach and distance between the two.

[0048] Specifically, such as Figures 3-6As shown, the holding and buffering mechanism 11 includes an air storage frame 111 installed outside the sliding frame 1. A movable plate 112 is slidably connected inside the air storage frame 111. A crossbar 113 is fixedly connected to the side of the movable plate 112. A pressure plate 114 is fixedly connected to one end of the crossbar 113 located outside the air storage frame 111. An extension block 115 is fixedly connected to the side of the pressure plate 114. The extension block 115 is fixedly connected to the end of the connecting rope 16. A hand groove for hand gripping is provided on the front of the air storage frame 111.

[0049] A crossbar 113 passes through and is slidably connected to the side of the air storage frame 111. A first elastic component 116 is fixedly connected to the outside of the movable plate 112. The first elastic component 116 is fixedly connected to the inner wall of the air storage frame 111. The air storage frame 111 is connected to the intermediate pipe 12. An air outlet pipe 117 is connected to the air storage frame 111. An air jet head 118 is connected to the end of the air outlet pipe 117.

[0050] The hand is placed in the hand groove and the pressure plate 114 is controlled to move closer to the air storage frame 111. At the same time, the other pressure plates 114 are controlled to move synchronously through the connecting rope 16. At this time, the gas in the air storage frame 111 is squeezed out through the air outlet pipe 117 and the air nozzle 118. The blown gas acts on the upper side of the tarpaulin 3. The air storage frame 111 draws gas from the air cylinder 131 through the middle pipe 12.

[0051] Specifically, such as Figures 4-5 and Figures 7-8 As shown, the lateral moving mechanism 13 includes an air cylinder 131, a fixed column 132 is fixedly connected to the side of the air cylinder 131, the fixed column 132 is fixedly connected to the outside of the second support rod 6, the air cylinder 131 is connected to the intermediate tube 12, a circular plate 133 is slidably connected inside the air cylinder 131, an intermediate rod 134 is fixedly connected to the side of the circular plate 133, and a toothed rod 135 is fixedly connected to the end of the intermediate rod 134. The toothed rod 135 is located outside the rotary extrusion mechanism 14.

[0052] The gas in the air cylinder 131 is connected to the air storage frame 111 through the intermediate pipe 12, which facilitates the control of the gas volume in the air cylinder 131 through the air storage frame 111, and uses the change in air pressure to control the horizontal linear movement of the circular plate 133 and the toothed rod 135.

[0053] The rotary extrusion mechanism 14 includes an extrusion wheel 141, a rotating shaft 142 is connected through the axial position on the side of the extrusion wheel 141, and a gear 143 is fixedly connected to the outside of the rotating shaft 142, the gear 143 meshing with the outside of the rack 135.

[0054] The rotating shaft 142 is fitted with two connecting bearings 144. The sides of the two connecting bearings 144 are fixedly connected to a fixing bracket 145. The fixing bracket 145 is fixedly connected to the outside of the second support rod 6. The extrusion wheel 141 is provided with an arc-shaped protrusion. The extrusion wheel 141 is located outside the movable striking mechanism 15.

[0055] During the movement of the rack 135, the gear 143 controls the rotation of the rotating shaft 142 and the extrusion wheel 141. When the extrusion wheel 141 rotates, its arc-shaped protrusion will squeeze the movable striking mechanism 15 to perform an action. The bearing provides stable support for the rotating shaft 142 and the gear 143, ensuring that the gear 143 and the rack 135 maintain a stable meshing state.

[0056] Specifically, such as Figures 4-5 and Figure 9 As shown, the movable striking mechanism 15 includes a connecting seat 151, a contact protrusion 152 on the connecting seat 151, the contact protrusion 152 is located outside the extrusion wheel 141, and two striking rods 156 are installed on the connecting seat 151, the striking rods 156 are located on the lower surface of the tarpaulin 3.

[0057] An extension rod 153 is installed on the connecting seat 151. A linear bearing 154 is fixedly connected to the end of the extension rod 153. The linear bearing 154 is linearly slidably connected to the outside of the first support rod 5. A second elastic component 155 is installed on the linear bearing 154. The top end of the second elastic component 155 is fixedly connected to the outside of the sliding frame 1. The second elastic component 155 is sleeved on the outside of the first support rod 5.

[0058] The linear bearing 154 and the first support rod 5 guide and limit the vertical movement of the connecting seat 151, ensuring that the striking rod 156 can stably perform vertical movements. The second elastic component 155 can control the connecting seat 151 and the striking rod 156 to quickly return to their original position after the connecting seat 151 loses its compression. The striking rod 156 is used to strike and vibrate the tarpaulin 3. When the contact protrusion 152 is squeezed by the compression wheel 141, it can move downward. When the arc-shaped protrusion passes the contact protrusion 152, the connecting seat 151 loses its compression.

[0059] Working principle and usage:

[0060] When the sunshade needs to be folded, you can hold it from the left and right sides, place your hands in the hand slots, and control the pressure plate 114 to move closer to the air storage frame 111. At the same time, control the other pressure plates 114 to move synchronously via the connecting rope 16. At this time, the gas in the air storage frame 111 is squeezed out through the air outlet pipe 117 and the air nozzle 118. The blown gas acts on the upper side of the tarpaulin 3. The air storage frame 111 draws gas from the air cylinder 131 through the middle pipe 12. The circular plate 133 and the middle rod 134 control the movement of the toothed rod 135. During the movement of 35, the gear 143 and the extrusion wheel 141 are controlled to rotate. During the rotation of the extrusion wheel 141, the arc-shaped protrusion on its surface will press against the contact protrusion 152. When the arc-shaped protrusion passes the contact protrusion 152, the second elastic component 155 controls the linear bearing 154 and the striking rod 156 to quickly return to the starting position. The striking rod 156 strikes and vibrates the tarpaulin 3, causing the leaves or debris on the surface of the tarpaulin 3 to vibrate and fall off. At the same time, the air blown out by the jet nozzle 118 onto the tarpaulin 3 allows the leaves and debris to fall off smoothly.

[0061] When the air storage frame 111 is held steadily and the pressure plate 114 is squeezed, the sliding frame 1 can be pushed closer to the center position to fold the sunshade device. While pushing the sliding frame 1, the pressure plate 114 is released, and the first elastic component 116 controls the moving plate 112 to reset. The gas in the air storage frame 111 is transferred to the air cylinder 131, which realizes the reset of the control rack 135. The rack 135 controls the gear 143 and the squeezing wheel 141 to rotate, which again realizes the control of the striking rod 156 to strike the tarpaulin 3. At this time, the part of the tarpaulin 3 between the two sliding frames 1 is squeezed and folded up. When the sliding frame 1 moves closer to the pressure plate 114, air is blown onto the loosened tarpaulin 3 again. The first elastic component 116 buffers and separates the sliding frame 1 during the approach and retraction process to prevent the sliding frame 1 from pinching the fingers, and the overall retraction process is smooth and stable.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
