Description

Technical Field

[0001] The utility model relates to the technical field of sunshades, in particular to an automatic push-pull opening and closing device for a household sunshade. Background Art

[0002] Household sunshades play various important roles in modern living environments. First of all, sunshades can effectively block direct sunlight. Especially in the hot summer, they can reduce the indoor temperature, improve indoor comfort, and reduce the usage frequency of cooling equipment such as air conditioners, thus saving energy consumption. Secondly, sunshades can prevent rainwater from directly entering areas such as patios or balconies on rainy days, protecting furniture and other items from rain erosion and extending their service life. In addition, sunshades can also provide a comfortable activity area for outdoor spaces such as balconies, courtyards or terraces, enabling these areas to be fully utilized under various weather conditions. Whether it is sunny or rainy, family members can relax, entertain or carry out other outdoor activities under the sunshade. Sunshades also provide a certain degree of privacy protection, especially in densely populated urban environments, effectively avoiding direct sightlines of neighbors or outsiders to family activities and enhancing the privacy of living.

[0003] In many traditional bungalow buildings, a fixed shed structure is usually used at the top of the patio. Although this design can provide the functions of sunshading and rain protection, it also brings many problems. First of all, the fixed shed cannot be opened, resulting in restricted air circulation in the patio area. In the hot summer, the unventilated patio will cause the indoor temperature to rise, affecting living comfort; in the wet and cold winter, the lack of ventilation will make it difficult for indoor moisture to be discharged, easily causing mildew and air quality problems.

[0046] Next, in conjunction with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] Embodiment 1:

[0048] Please refer to the attached Figure 1 - attached Figure 7 , the embodiment of the present invention provides an automatic push-pull opening and closing device for a household sunshade, including

[0049] Wall 1 and Wall 2, which are basic walls, and the sunshade is installed between Wall 1 and Wall 2;

[0050] Metal frame 18, which is the installation frame of the sunshade. A sunshade board 19 is installed on the top of the metal frame 18, and the sunshade board 19 can also be replaced with a color steel tile or a transparent resin tile;

[0051] Slide rail 3 is installed between Wall 1 and Wall 2. The metal frame 18 is slidably connected to the top of the slide rail 3. A guide wheel 4 is installed at the bottom of the metal frame 18, and the guide wheel 4 is located inside the slide rail 3. First, install the slide rail 3 between Wall 1 and Wall 2 by bolts or welding, then install the guide wheel 4 at the bottom of the metal frame 18, install the sunshade board 19 at the top of the metal frame 18, and finally assemble the guide wheel 4 with the slide rail 3, thus completing the preliminary assembly of the sunshade.

[0052] Please refer to the attached Figure 7, a driving component, which is used to drive the movement of the first metal framework 18. The driving component includes a motor 11 and a driven wheel 10. The motor 11 is fixedly connected to the inner side of the second wall 2, and the driven wheel 10 is rotatably connected to the inner side of the first wall 1. The output end of the motor 11 is fixedly connected with a driving wheel 12. A steel rope 13 is sleeved on the outer circumferences of the driven wheel 10 and the driving wheel 12. The bottom of the first metal framework 18 is fixedly connected with a towing rod 9, and the other end of the towing rod 9 is fixedly connected to the outer side of the steel rope 13; fix the towing rod 9 to the bottom of the first metal framework 18, and then when the driving motor 11 works, it can drive the driving wheel 12 to rotate. At this time, the steel rope 13 will operate under the action of the driven wheel 10 and the driving wheel 12. While the steel rope 13 is operating, it will provide a pulling force to the towing rod 9, so that the first metal framework 18 can be pulled along the running direction of the motor 11, thereby realizing the opening and closing of the first metal framework 18; flower basket screw tensioners 14 and hooked springs 15 are successively installed at the connection parts of the two ends of the steel rope 13. The tension of the steel rope 13 can be adjusted through the flower basket screw tensioners 14 and the hooked springs 15, so as to ensure that the steel rope 13 fully frictional engages with the driven wheel 10 and the driving wheel 12 to ensure the normal opening and closing of the first metal framework 18.

[0053] Please refer to the appendix Figure 11 , a controller, which is used to control the operation of the motor 11. The opening and closing of the first metal framework 18 can be directly controlled through the controller.

[0054] Please refer to the appendix Figure 3 - appendix Figure 5 , a stroke limiting component, which is used to limit the moving stroke of the slide rail 3. The stroke limiting component is installed between the first wall 1 and the second wall 2. The stroke limiting component includes a first stroke limit switch 20, a trigger baffle 21 and a second stroke limit switch 22. The first stroke limit switch 20 is fixedly connected to the inner side of the first wall 1, the trigger baffle 21 is fixedly connected to the inner side of the second wall 2, and the second stroke limit switch 22 is fixedly connected to the bottom of the first metal framework 18. The first stroke limit switch 20, the trigger baffle 21 and the second stroke limit switch 22 are on the same horizontal line; when driving the motor 11 to open the first metal framework 18, at this time the first metal framework 18 will drive the second stroke limit switch 22 to move synchronously. When the first metal framework 18 is opened to a specific position, the second stroke limit switch 22 will contact the first stroke limit switch 20. At this time, the first stroke limit switch 20 will transmit an electrical signal to the controller, and the controller will stop the operation of the motor 11 after receiving the electrical signal. On the contrary, when the first metal framework 18 is closed, the second stroke limit switch 22 will contact the trigger baffle 21. At this time, the trigger baffle 21 will also transmit an electrical signal to the controller, and the controller will stop the operation of the motor 11 after receiving the electrical signal, thereby realizing the quick opening and closing of the sunshade and reducing the operation steps during control.

[0055] Please refer to the appendix Figure 3 - appendixFigure 5 At the bottom of the first metal framework 18, a support rod 23 is fixedly connected. At the bottom of the support rod 23, a roller 16 is rotatably connected. The roller 16 is in contact with the bottom of the slide rail 3. When the first metal framework 18 moves, the roller 16 will roll along the bottom of the slide rail 3, thereby restricting the position of the first metal framework 18 and making the movement of the first metal framework 18 more stable.

[0056] Please refer to the appendix Figure 5 - appendix Figure 6 At the bottom of the slide rail 3, a housing 5 is also fixedly connected. At the bottom of the housing 5, a support rod 28 is rotatably connected. At the bottom of the support rod 28, a runner 6 is rotatably connected. The runner 6 is located inside the slide rail 3. A connecting rod 7 is rotatably connected to the outside of the support rod 28. The other end of the connecting rod 7 is rotatably connected to a compression spring 8. The other end of the compression spring 8 is fixedly connected inside the housing 5. When the first metal framework 18 moves, the runner 6 will roll inside the slide rail 3. When the support rod 28 contacts the edge of the first wall 1, the support rod 28 will be blocked and rotate. At this time, the support rod 28 will retract the runner 6 to facilitate the movement of the first metal framework 18. When the first metal framework 18 is closed, when the runner 6 disengages from the top of the first wall 1, the compression spring 8 can act on the connecting rod 7. Under the connection of the connecting rod 7, the support rod 28 will be pushed back again. At this time, the runner 6 can re-enter the slide rail 3, thereby facilitating the movement of the first metal framework 18.

[0057] Please refer to the appendix Figure 5 At the bottom of the first metal framework 18, multiple rubber wheels 17 are installed. The rubber wheels 17 are located at the upper part of the first wall 1 and are used to reduce the friction when the first metal framework 18 moves. When the first metal framework 18 is opened and closed, the rubber wheels 17 will contact the upper surface of the first wall 1, thereby guiding the first metal framework 18 and avoiding the noise and static friction generated by the direct contact between the first metal framework 18 and the first wall 1.

[0058] Please refer to the appendix Figure 1 - appendix Figure 4 At the top of the second wall 2, a sealing strip 24 is fixedly connected. The edge of the first metal framework 18 is in contact with the top of the sealing strip 24. After adding the sealing strip 24 at the top of the second wall 2, the connection position between the first metal framework 18 and the sealing strip 24 can be sealed, thereby reducing or avoiding rainwater from seeping in through the gap.

[0059] Please refer to the appendix Figure 11, a humidity sensor is installed at the top of the second wall 2. The humidity sensor is electrically connected to an external controller, and the controller is electrically connected to the motor 11. When the first metal frame 18 is open and rainy weather occurs, the humidity sensor will detect the humidity change in the current environment and convert these changes into electrical signals and transmit them to the controller. When it detects that the humidity exceeds the set threshold, the controller will automatically control the motor 11 to work to retract the first metal frame 18, thereby improving the usability of the sunshade;

[0060] Please refer to the appendix Figure 3 - appendix Figure 4 , water diversion strips 25 are fixedly connected to the inner sides of the first wall 1 and the second wall 2. The water diversion strips 25 are used to guide the accumulated water on the tops of the first wall 1 and the second wall 2. The accumulated water on the tops of the first wall 1 and the second wall 2 will be guided by the water diversion strips 25 and flow to both sides of the first wall 1 and the second wall 2, thereby preventing rainwater from entering the space between the first wall 1 and the second wall 2 and improving the rain protection performance of the sunshade.

[0061] Embodiment 2:

[0062] Please refer to the appendix Figure 8 - appendix Figure 10 , as part of this application, the present utility model also provides a new embodiment.

[0063] An automatic push-pull opening and closing device for a household sunshade, including

[0064] The first wall 1 and the second wall 2 are basic walls, and the sunshade is installed between the first wall 1 and the second wall 2;

[0065] The first metal frame 18 is a sunshade installation frame, and a sunshade panel 19 is installed on the top of the first metal frame 18;

[0066] The slide rail 3 is installed between the first wall 1 and the second wall 2. The first metal frame 18 is slidably connected to the top of the slide rail 3, and a guide wheel 4 is installed at the bottom of the first metal frame 18. The guide wheel 4 is located inside the slide rail 3. First, the slide rail 3 is installed between the first wall 1 and the second wall 2 by bolts or welding, then the guide wheel 4 is installed at the bottom of the first metal frame 18, the sunshade panel 19 is installed on the top of the first metal frame 18, and finally the guide wheel 4 is assembled with the slide rail 3, thereby completing the preliminary assembly of the sunshade.

[0067] Please refer to the appendix Figure 7, a driving component for driving the movement of the first metal framework 18. The driving component includes a motor 11 and a driven wheel 10. The motor 11 is fixedly connected to the inner side of the second wall 2, and the driven wheel 10 is rotatably connected to the inner side of the first wall 1. The output end of the motor 11 is fixedly connected with a driving wheel 12. A steel wire rope 13 is sleeved on the outer circumferences of the driven wheel 10 and the driving wheel 12. A turnbuckle tensioner 14 and a hook spring 15 are sequentially installed at the connection of the two ends of the steel wire rope 13. The bottom of the first metal framework 18 is fixedly connected with a towing bar 9, and the other end of the towing bar 9 is fixedly connected to the outer side of the steel wire rope 13. Fix the towing bar 9 to the bottom of the first metal framework 18, and then when the driving motor 11 works, it can drive the driving wheel 12 to rotate. At this time, the steel wire rope 13 will operate under the action of the driven wheel 10 and the driving wheel 12. While the steel wire rope 13 is operating, it will provide a pulling force to the towing bar 9, so that the first metal framework 18 can be pulled along the running direction of the motor 11, thereby realizing the opening and closing of the first metal framework 18. A turnbuckle tensioner 14 and a hook spring 15 are sequentially installed at the connection of the two ends of the steel wire rope 13. The tension of the steel wire rope 13 can be adjusted through the turnbuckle tensioner 14 and the hook spring 15 to ensure that the steel wire rope 13 fully frictional engages with the driven wheel 10 and the driving wheel 12 to ensure the normal opening and closing of the first metal framework 18.

[0068] Please refer to the appendix Figure 11 , a controller for controlling the operation of the motor 11. Through the controller, the opening and closing of the first metal framework 18 can be directly controlled.

[0069] Please refer to the appendix Figure 8 - appendix Figure 9 , a second metal framework 26 is fixedly connected to the outer side of the first wall 1. A sunshade 19 is installed on the top of the second metal framework 26. The first metal framework 18 is located above the second metal framework 26. After adding the second metal framework 26, the space between the first wall 1 and the second wall 2 is divided into two parts, which is suitable for areas with a small space at the top of the first wall 1. In this case, after the first metal framework 18 is opened, it will move above the second metal framework 26.

[0070] Please refer to the appendix Figure 9, a travel limit component, used to limit the moving travel of the slide rail 3; the travel limit component is installed between the second metal framework 26 and the second wall 2. The travel limit component includes a first travel limit switch 20, a trigger baffle 21, and a second travel limit switch 22. The first travel limit switch 20 is fixedly connected to the inner side of the second metal framework 26, the trigger baffle 21 is fixedly connected to the inner side of the second wall 2, and the second travel limit switch 22 is fixedly connected to the bottom of the first metal framework 18. The first travel limit switch 20, the trigger baffle 21, and the second travel limit switch 22 are on the same horizontal line. When the driving motor 11 is used to open the first metal framework 18, at this time, the first metal framework 18 will drive the second travel limit switch 22 to move synchronously. When the first metal framework 18 is opened to a specific position, the second travel limit switch 22 will contact the first travel limit switch 20. At this time, the first travel limit switch 20 will transmit an electrical signal to the controller. After receiving the electrical signal, the controller will stop the motor 11. On the contrary, when the first metal framework 18 is closed, the second travel limit switch 22 will contact the trigger baffle 21. At this time, the trigger baffle 21 will also transmit an electrical signal to the controller. After receiving the electrical signal, the controller will stop the motor 11. Thus, the rapid opening and closing of the sunshade are realized, and the operation steps during control are reduced.

[0071] Please refer to the appendix Figure 10 , a support rod 23 is fixedly connected to the bottom of the first metal framework 18. The bottom of the support rod 23 is rotatably connected to a roller 16, and the roller 16 is in contact with the bottom of the slide rail 3. When the first metal framework 18 moves, the roller 16 will roll along the bottom of the slide rail 3. Thus, the position of the first metal framework 18 can be restricted, making the movement of the first metal framework 18 more stable.

[0072] Please refer to the appendix Figure 8 - appendix Figure 11 , a diagonal brace 27 is fixedly connected to the bottom of the second metal framework 26, and the other end of the diagonal brace 27 is fixedly connected to the inner side of the first wall 1. The diagonal brace 27 provides support for the second metal framework 26 to ensure the stability of the second metal framework 26. A sealing strip 24 is fixedly connected to the top of the second wall 2. The edge of the first metal framework 18 is in contact with the top of the sealing strip 24. A humidity sensor is installed on the top of the second wall 2. The humidity sensor is electrically connected to an external controller, and the controller is electrically connected to the motor 11. When the first metal framework 18 is opened and it is a rainy day, the humidity sensor will detect the humidity change of the current environment and convert these changes into electrical signals and transmit them to the controller. When it is detected that the humidity exceeds the set threshold, the controller will automatically control the motor 11 to work to retract the first metal framework 18. Thus, the use convenience of this sunshade can be improved.

[0073] Working principle: When in use, when it is necessary to open the sunshade, just drive the external remote control to transmit an electrical signal to the controller, and then control the motor 11 to work through the controller to drive the driving wheel 12 to rotate. As a result, the steel rope 13 can move between the driving wheel 12 and the driven wheel 10, thereby acting on the traction rod 9, and thus the metal framework one 18 can be pulled outward. At this time, the metal framework one 18 will slide on the top of the slide rail 3 through the guide wheel 4 to open the sunshade, thereby realizing ventilation and air exchange in areas such as indoors and the patio.

[0074] When the metal framework one 18 is driven by the motor 11 to move, the travel limit switch two 22 will move synchronously. When the sunshade is opened, when the travel limit switch two 22 contacts the travel limit switch one 20, the travel limit switch one 20 sends an electrical signal to the controller. At this time, the controller makes the motor 11 stop working, thus completing the opening of the sunshade. On the contrary, when the sunshade is closed, after the travel limit switch two 22 contacts the trigger baffle 21, the motor 11 stops working.

[0075] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
