Description

Technical Field

[0001] This utility model relates to the field of RV accessories technology, and more specifically, to a wind-resistant self-locking hinge mechanism for an electric RV awning. Background Technology

[0002] With the increasing popularity of RV travel, RV awnings, as a key accessory to enhance the outdoor experience, have attracted much attention for their performance.

[0003] Existing patent publication number CN218055002U discloses an automated RV awning, including a vehicle body. A retractable roller is fixedly installed on one side of the top of the vehicle body, and a sunshade cloth is fixedly wound on the retractable roller. A motor is installed on one end of the vehicle body near the retractable roller, and the drive shaft of the motor is drivenly connected to the central shaft of the retractable roller. A drive mechanism is installed on the other side of the top of the vehicle body. The retractable roller allows the awning to be rolled up when not in use, preventing wrinkles and damage. A slide rail is provided to support the extended scissor-type arm, improving stability. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Most existing awning hinge mechanisms are relatively simple in structure and lack effective wind-resistant design. When encountering strong winds, the awning is prone to violent shaking due to the wind force, which not only affects the user's normal activities, but may also cause structural damage to the awning due to long-term uneven stress, shortening its service life. At the same time, after the awning is deployed, if a sudden strong wind occurs, it cannot automatically lock the position of the awning to maintain a stable state, leaving the awning in a passive state under strong winds, increasing the risk of damage and posing a potential threat to the user's safety.

[0005] Therefore, a wind-resistant self-locking hinge mechanism for motorhome electric awnings is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wind-resistant self-locking hinge mechanism for electric RV awnings to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wind-resistant self-locking hinge mechanism for an electric RV awning, comprising a support frame, with fixed plates welded to the left and right sides of the support frame; a winding mechanism is provided inside the support frame, the winding mechanism including a winding motor, the output end of which is tightly connected to a winding rod via a coupling; a tensioning mechanism is provided inside the support frame, the tensioning mechanism including a bidirectional motor, the output end of which is directly connected to an external threaded rod; two internal threaded sleeves are symmetrically threaded on the external threaded rod, each internal threaded sleeve being equipped with a positioning cylinder at its bottom; a positioning rod is connected to the top of each positioning cylinder via a movable connection; the positioning rod is designed to penetrate the bottom of the internal threaded sleeve and contact the bottom of the external threaded rod; furthermore, a mounting frame is fixedly provided at the bottom of each internal threaded sleeve, the mounting frame being located outside the positioning cylinder.

[0008] Preferably, the winding rod is horizontally arranged inside the support frame, and first positioning plates are symmetrically arranged at the left and right ends of the winding rod. The first positioning plates are fixed to the inner walls of the left and right sides of the support frame by bolts. At the same time, limit baffles are also fixedly installed at the left and right ends of the winding rod. In addition, a first bearing is nested at the end of the winding rod away from the drive end of the winding motor. The first bearing is also embedded and fixed in the corresponding inner wall of the support frame.

[0009] Preferably, the thread on the outer side of the external threaded rod is a bidirectional thread structure, and a second bearing is installed at the end of the external threaded rod away from the bidirectional motor drive. The second bearing is embedded and fixed in the corresponding inner wall of the bearing frame.

[0010] Preferably, a second positioning piece is provided at both the left and right ends of the external threaded rod. The second positioning piece is adapted to the diameter of the external threaded rod and the internal structure of the bearing frame, and the bottom of the second positioning piece is in contact with the inner surface of the bearing frame.

[0011] Preferably, a movable rod is detachably mounted on the upper side of the internal threaded sleeve, and a first pin is embedded inside the movable rod. The first pin passes through the movable rod and is aligned with a corresponding hole on the internal threaded sleeve.

[0012] Preferably, the end of the movable rod away from the internal threaded sleeve is connected to a support rod via a connecting structure, and a detachable mounting groove is provided on the upper side of the support rod, with a second pin placed inside the mounting groove.

[0013] Preferably, the end of the support rod away from the end connected to the movable rod has a positioning hole. The internal structure of the positioning hole is smooth, which can accommodate and detachably insert a bearing block. The outer contour of the bearing block fits the positioning hole.

[0014] Preferably, a sunshade cloth is arranged on the outer side of the winding rod in a spiral winding manner, and the end of the sunshade cloth is in contact with the upper surface of the support block.

[0015] Preferably, a guide rod is fixedly connected to the bottom of the mounting frame, and a limit rod is fixedly installed at a corresponding position inside the bearing frame. The limit rod is located directly below the external threaded rod, and the bottom of the guide rod is in close contact with the inside of the limit rod. When the mounting frame moves, the guide rod will slide along the inside of the limit rod.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] Compared with existing technologies, this wind-resistant self-locking hinge mechanism for RV electric awnings uses a bidirectional motor to drive an external threaded rod. Its bidirectional threaded structure allows two internal threaded sleeves to move symmetrically. Together with movable rods, support rods, and other components, it can stably unfold and support the awning fabric, forming a stable support system. When encountering strong winds, the components work together to effectively disperse the wind force, reduce the swaying of the awning fabric, greatly enhance the wind resistance of the awning, and extend its service life.

[0018] Compared with existing technologies, this wind-resistant self-locking hinge mechanism for RV electric awnings plays a key role through the positioning cylinder and positioning rod equipped at the bottom of the internal threaded sleeve. When the awning is unfolded to the appropriate position, the positioning cylinder pushes the positioning rod through the bottom of the internal threaded sleeve and into contact with the bottom of the external threaded rod, achieving mechanical self-locking. This prevents the awning from accidentally rolling up or shaking due to the external threaded rod rotating under external force, ensuring the stability of the awning in harsh environments such as strong winds.

[0026] Example 1

[0027] As attached Figures 1 to 5 The illustrated motorhome electric awning windproof self-locking hinge mechanism includes a support frame 1. Fixing plates 2 are welded and fixed to the left and right sides of the support frame 1. A winding mechanism is installed inside the support frame 1, including a winding motor 3. The output end of the winding motor 3 is tightly connected to a winding rod 4 via a coupling. A tensioning mechanism is installed inside the support frame 1, including a bidirectional motor 8. The output end of the bidirectional motor 8 is directly connected to an external threaded rod 9. Two internal threaded sleeves 12 are symmetrically threaded on the external threaded rod 9. Each internal threaded sleeve 12 is equipped with a positioning cylinder 20 at its bottom. A positioning rod 21 is movably connected above the positioning cylinder 20. The positioning rod 21 is designed to penetrate the bottom of the internal threaded sleeve 12 and contact the bottom of the external threaded rod 9. Furthermore, a mounting frame 22 is fixedly installed at the bottom of the internal threaded sleeve 12, located outside the positioning cylinder 20.

[0028] Specifically: the winding motor 3 is tightly connected to the winding rod 4 via a coupling, which can stably achieve the winding of the sunshade cloth 19, ensuring a reliable structure; the bidirectional motor 8 is directly connected to the external threaded rod 9, and together with the two symmetrically threaded internal threaded sleeves 12, it can precisely control the stretching action, ensuring that the sunshade cloth 19 unfolds evenly; secondly, the design of the positioning cylinder 20 and the positioning rod 21, with the positioning rod 21 passing through the bottom of the internal threaded sleeve 12 and contacting the bottom of the external threaded rod 9, can achieve self-locking when encountering external forces such as strong winds, enhancing wind resistance and ensuring safe use; thirdly, the mounting frame 22 is fixed to the bottom of the internal threaded sleeve 12 and located outside the positioning cylinder 20, providing protection for the internal structure, while making the overall layout more compact and reasonable, improving the overall stability and durability of the mechanism, and extending its service life.

[0029] Example 2

[0030] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0031] In a preferred embodiment, the winding rod 4 is horizontally arranged inside the support frame 1. First positioning plates 5 are symmetrically arranged at the left and right ends of the winding rod 4. The first positioning plates 5 are fixed to the inner walls of the left and right sides of the support frame 1 by bolts, which play a role in initial positioning and support. At the same time, limit baffles 6 are also fixedly installed at the left and right ends of the winding rod 4 to prevent the material from shifting and falling off during the winding process. In addition, a first bearing 7 is nested at the end of the winding rod 4 away from the drive end of the winding motor 3. The first bearing 7 is also embedded and fixed in the corresponding inner wall of the support frame 1 to ensure that the winding rod 4 can remain stable and reduce friction when rotating.

[0032] As a preferred embodiment, the outer thread of the external threaded rod 9 adopts a bidirectional thread structure, which enables bidirectional synchronous movement when it is engaged with the internal threaded sleeve 12. A second bearing 10 is installed at the end of the external threaded rod 9 away from the bidirectional motor 8. The second bearing 10 is embedded and fixed in the corresponding inner wall of the bearing frame 1, which not only ensures the stability of the external threaded rod 9 during rotation and reduces friction and wear, but also greatly improves the smoothness and reliability of the entire tensioning mechanism.

[0033] In a preferred embodiment, a second positioning piece 11 is provided at both the left and right ends of the external threaded rod 9. The second positioning piece 11 is adapted to the diameter of the external threaded rod 9 and the internal structure of the bearing frame 1. The bottom of the second positioning piece 11 contacts the inner surface of the bearing frame 1, ensuring that the external threaded rod 9 can remain stable and not deviate when rotating, effectively preventing positioning deviation caused by vibration or external force.

[0034] In a preferred embodiment, a movable rod 13 is detachably mounted on the upper side of the internal threaded sleeve 12. The connection between the movable rod 13 and the internal threaded sleeve 12 is designed such that a first pin 14 is embedded inside the movable rod 13. The first pin 14 passes through the movable rod 13 and is aligned with the corresponding hole on the internal threaded sleeve 12. During installation, simply place the movable rod 13 in the designated position of the internal threaded sleeve 12 and then insert the first pin 14 to achieve positioning between the internal threaded sleeve 12 and the movable rod 13. This facilitates quick assembly and disassembly and ensures structural stability after connection.

[0035] In a preferred embodiment, the end of the movable rod 13 away from the internal threaded sleeve 12 is connected to the support rod 15 through a connecting structure to ensure that the two can work together when under force. A detachable mounting groove is provided on the upper side of the support rod 15, and a second pin 16 is placed inside the mounting groove. The positioning between the support rod 15 and the movable rod 13 is achieved through the action of the second pin 16, which not only ensures the stability of the structure, but also facilitates subsequent disassembly and maintenance.

[0036] As a preferred embodiment, the end of the support rod 15 away from the connection with the movable rod 13 is provided with a positioning hole 17. The internal structure of the positioning hole 17 is smooth, which can accommodate and detachably insert the bearing block 18. The outer contour of the bearing block 18 fits the positioning hole 17. When installation is required, simply align the bearing block 18 with the positioning hole 17 and gently push it in to achieve a stable connection, which facilitates subsequent disassembly and replacement.

[0037] In a preferred embodiment, a sunshade cloth 19 is spirally wound on the outer side of the winding rod 4. The sunshade cloth 19 is made of durable material and has excellent sunshade and windproof performance. When the winding rod 4 is driven by the winding motor 3 to rotate, the sunshade cloth 19 can be unfolded or retracted in an orderly manner. The end of the sunshade cloth 19 is in contact with the upper surface of the support block 18. The support block 18 provides a stable support point for the end of the sunshade cloth 19, ensuring that the sunshade cloth 19 will not shift or shake during unfolding and rewinding, thus ensuring the overall stability of the sunshade awning.

[0038] In a preferred embodiment, a guide rod 23 is fixedly connected to the bottom of the mounting frame 22. The guide rod 23 extends vertically downward and has a smooth and straight surface to ensure smooth sliding. A limit rod 24 is fixedly installed at a corresponding position inside the bearing frame 1. The limit rod 24 is located directly below the external threaded rod 9 and plays an important limiting role. The bottom of the guide rod 23 is in close contact with the inside of the limit rod 24. When the mounting frame 22 moves, the guide rod 23 will slide along the inside of the limit rod 24, thereby effectively limiting the movement trajectory, preventing deviation, and ensuring the stability of the entire device operation.

[0039] In this embodiment, the carrier frame 1, the winding motor 3, and the bidirectional motor 8 are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0040] The working process of this utility model is as follows: When in use, firstly, the bidirectional motor 8 drives the external threaded rod 9 to rotate. Its bidirectional thread causes the two internal threaded sleeves 12 to move symmetrically. The internal threaded sleeves 12 drive the movable rod 13 and the support rod 15 to move. The bearing block 18 in the positioning hole 17 at the end of the support rod 15 pulls the sunshade cloth 19 to unfold. The first positioning piece 5, the limit baffle 6 and the first bearing 7 at both ends of the winding rod 4 ensure its stability. The second positioning piece 11 at both ends of the external threaded rod 9 assists in positioning. At the same time, the guide rod 23 at the bottom of the mounting frame 22 slides along the limit rod 24 to ensure that the internal threaded sleeve 12 moves smoothly. Then, after the sunshade cloth 19 is unfolded into place, the positioning cylinder 20 at the bottom of the internal threaded sleeve 12 pushes the positioning rod 21 through the bottom of the internal threaded sleeve 12 and into contact with the bottom of the external threaded rod 9 to achieve mechanical self-locking and prevent the external threaded rod 9 from rotating and causing the sunshade cloth 19 to be accidentally rolled up or shaken.

[0041] Finally, the self-locking mechanism is released, and the winding motor 3 drives the winding rod 4 to rotate via the coupling, so that the sunshade cloth 19 is re-spirally wound onto the winding rod 4.

[0042] The above describes the working principle of a wind-resistant self-locking hinge mechanism for an electric RV awning.
