[0034] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0035] This application claims protection for a push rod structure for realizing a lateral push-pull movable rod, which can be a telescopic quilt drying rod in a clothes drying rack. The clothes drying rack typically includes a main unit and a drying assembly controlled by the main unit. The quilt drying rod is usually arranged along the longitudinal direction of the drying assembly. As a movable structure relative to a fixed drying rod, the switching between the retracted state and the extended state always requires at least lateral exposure of the quilt drying rod body. The push rod structure of this application can realize the lateral push-out or lateral push-in of the quilt drying rod, assisting in realizing the extension or retraction of the quilt drying rod.
[0036] Specifically, refer to Figures 1-8 The push rod structure of this application includes:
[0037] Driven rod 1, the outer end of which is orthogonally connected to the end of the movable rod, is used to link with the movable rod that moves laterally;
[0038] The fixing buckle 2 is connected to the inner end of the driven rod 1 and is used to transmit the push and pull force to make the driven rod 1 translate.
[0039] The motor 3 and the transmission assembly, wherein the transmission assembly is connected to the motor 3 via a clutch 41 and transmits the torque output by the motor 3 to the fixed buckle 2;
[0040] End box 5 is used to house driven rod 1, retaining buckle 2, motor 3 and transmission assembly;
[0041] The limit plug 6 is located at the lateral end of the end box 5 to prevent the driven rod 1 from coming out.
[0042] refer to Figure 1 and 2The end box 5 serves two purposes: firstly, it acts as the longitudinal end structure for fixing the drying rod, protecting or decorating it; secondly, it serves as the outer shell of the push rod structure in this application, protecting and concealing the interior of the push rod structure. In this embodiment, the inner side of the end box 5 is used for the assembly connection of the drying rod, and the outer side can also be equipped with an end cap 8 to enhance the decorative appearance of the end box 5. The two lateral ends of the end box 5 are closed by limiting plugs 6, and the end box 5 presents a square tubular structure.
[0043] In this embodiment, as Figure 2 As shown, the limiting plug 6 has a smooth outer surface to form a uniform appearance with the outer surface of the end box 5. The inner side of the limiting plug 6 is provided with a matching plug-in structure to adapt to the cross-sectional shape of the end box 5. Furthermore, the limiting plug 6 also includes a transverse guide groove 61 that is recessed relative to its outer surface, and the end opening of the guide groove 61 is provided with a guide port 62. The guide port 62 is used to expose the linkage plug 11 used to connect the driven rod 1 and the moving rod. The outer contour dimension of the cross-section of the linkage plug 11 is larger than that of the guide port 62 and smaller than that of the inner cavity of the cross-section of the guide groove 61. Therefore, the linkage plug 11 cannot pass through the guide port 62, but can translate within the guide groove 61 to adapt to the translation trajectory of the linkage plug 11. The guide groove 61 opens towards the moving rod and the direction of the moving rod's extension. Furthermore, the shape of the guide opening 62 matches the cross-sectional outer contour of the driven rod 1. The size of the guide opening 62 is larger than the cross-sectional outer contour size of the driven rod 1 and smaller than the cross-sectional outer contour size of the fixing buckle 2. Thus, the guide opening 62 allows the driven rod 1 to extend out from the guide opening 62, but the extension length of the driven rod 1 is limited by the fixing buckle 2.
[0044] In this embodiment, the linkage plug 11 provides two mutually perpendicular slot structures to accommodate the orthogonal connection orientation of the driven rod 1 and the movable rod, respectively fitting the cross-sectional profile of the inner cavity of the driven rod 1 and the cross-sectional profile of the inner cavity of the movable rod. Due to the limitations of its body structure, the linkage plug 11 cannot pass through the guide opening 62 of the limiting plug 6, thereby limiting the length of the driven rod 1 that is pushed into the end box 5.
[0045] To fully utilize the space inside the end box 5, the maximum length of each driven rod 1 can span between two opposing guide openings 62. In one possible embodiment, each fixed drying rod is provided with a push rod structure of this application at both ends. Each push rod structure is configured with two driven rods 1 in opposite directions. Thus, each push rod structure provides two linkage plugs 11. The two linkage plugs 11 on the same push rod structure connect different movable rods. Thus, each movable rod is configured with two linkage plugs 11 belonging to different push rod structures and corresponding driven rods 1.
[0046] The lateral translation of the two driven rods 1 in the same push rod structure can be synchronously controlled by a set of motors 3 and transmission components. The control methods in this embodiment include scenarios where automatic control is performed by motor 3, and scenarios where control is performed manually without motor 3. The transmission components are described in detail below.
[0047] The transmission assembly of this embodiment includes a drive wheel 42 that meshes with the output shaft of the motor 3, a clutch 41 that selectively meshes with the drive wheel 42, a first driven wheel 43 that is linked to the clutch 41, a synchronous belt 44 driven by the first driven wheel 43, and a second driven wheel 45 that tensions the synchronous belt 44, wherein a fixing buckle 2 is clamped on the synchronous belt 44. The push rod structure of this application also includes an inner bracket 7 for fixing or limiting the transmission assembly. In this embodiment, the inner bracket 7 is disposed below the driven rod 1, so that the transmission assembly is mainly disposed below the driven rod 1, and the inner bracket 7 and the transmission assembly are housed in the lower half of the end box 5.
[0048] refer to Figures 4-6The clutch 41 includes a clutch element 411, a first axle 412 passing through the clutch element 411, and a movable gear 413 coaxially and movably sleeved with the clutch element 411. The first driven wheel 43, the clutch element 411, and the movable gear 413 are installed sequentially from top to bottom. The movable gear 413 can mesh with the driving wheel 42. When the movable gear 413 meshes with the driving wheel 42, the rotation of the movable gear 413 drives the clutch element 411 to rotate, which in turn drives the first driven wheel 43 to rotate. The rotation of the first driven wheel 43 drives the synchronous belt 44 to move, which in turn drives the fixed buckle 2 to move, which in turn drives the driven rod 1 to move, thereby achieving the translation of the movable rod. When the movable gear 413 meshes with the driving wheel 42, the forward rotation of the driving wheel 42 can drive the driven rod 1 to translate laterally outward, pushing out the movable rod; the reverse rotation of the driving wheel 42 can drive the driven rod 1 to translate laterally inward, pushing in the movable rod. When the clutch 411 drives the movable gear 413 to disengage from the driving wheel 42, the driven rod 1 is no longer controlled by the motor 3, but can be pushed in or out by external force. This external force can be the force exerted by the user pulling the movable rod and transmitted to the first driven wheel 43 and the second driven wheel 45. Thus, manual control of the movable rod's retraction and extension can be achieved. At this time, the translation of the movable rod can drive the driven rod 1 to translate, the translation of the driven rod 1 can drive the fixed buckle 2 to translate, the translation of the fixed buckle 2 can drive the synchronous belt 44 to move, and the movement of the synchronous belt 44 can drive the first driven wheel 43 and the second driven wheel 45 to rotate. Optionally, the engagement state of the clutch 41 and the driving wheel 42, as well as the rotation direction and speed of the motor 3, can be controlled by the control block 46. The control commands received by the control block 46 can be obtained through level signal conversion, wireless communication signal conversion, or voice signal conversion. Furthermore, the state control of the clutch 411 on the movable gear 413 can also be achieved based on the principles of mechanical adjustment, electromagnetic adjustment, pneumatic adjustment, hydraulic adjustment or electronic adjustment.
[0049] refer to Figure 3 To achieve smooth transmission, the connecting line between the first driven wheel 43 and the second driven wheel 45 is parallel to the translational trajectory of the driven rod 1. The synchronous belt 44 is divided into two equal-length segments by the first driven wheel 43 and the second driven wheel 45, and the diameters of the first driven wheel 43 and the second driven wheel 45 are adapted to the spacing between the two driven rods 1, so that the two segments of the synchronous belt 44 are located directly below the driven rods 1, facilitating the connection between the driven rods 1 and the synchronous belt 44 using the fixing buckles 2, thus minimizing the torque generated. Each segment of the synchronous belt 44 is equipped with a fixing buckle 2, meaning that each segment of the synchronous belt 44 controls one driven rod 1, and the two fixing buckles 2 are located on either side of the midpoint of the connecting line between the first driven wheel 43 and the second driven wheel 45, ensuring that the two driven rods 1 always translate synchronously towards each other. Therefore, whether controlled by the motor 3 or manually, the two driven rods 1 can be pushed out or pushed in synchronously.
[0050] refer to Figure 7 and 8 The fixing buckle 2 includes a main buckle body 21 and a clip 22 below the main buckle body 21. The main buckle body 21 is a frame-shaped structure with an opening on one side, used to wrap around the inner end of the driven rod 1 by an interference fit to fix the driven rod 1. Furthermore, to improve the stability of the translation of the driven rod 1 by the fixing buckle 2, a structure that can cooperate with each other to achieve sliding is provided between the main buckle body 21 and the inner surface of the end box 5. One possible implementation is to provide a protruding guide hook on the outer surface of the main buckle body 21, and correspondingly, a guide rail that cooperates with the guide hook is provided on the inner surface of the end box 5. In this embodiment, the driven rod 1 is located in the upper half of the end box 5. The main buckle body 21 has a lower guide hook 212 protruding from its lower edge near the side wall of the end box 5. A lower rail 52 supporting the lower guide hook 212 is provided on the movement trajectory of the lower guide hook 212. The lower rail 52 is provided along the inner side wall of the end box 5. The main buckle body 21 has an upper guide hook 211 protruding from its upper edge near the top wall of the end box 5. An upper rail 51 supporting the upper guide hook 211 is provided on the movement trajectory of the upper guide hook 211. Since the two driven rods 1 are close to each other, the two corresponding upper rails 51 can be arranged in a simplified manner. The guide grooves on both sides are arranged side by side on the center line of the top wall of the end box 5. The upper rail 51 is provided along the inner top wall of the end box 5. The belt clip 22 includes a detachable upper belt clip 221 and a lower belt clip 222 that interlock with each other. The upper belt clip 221 is fixedly connected to the main buckle body 21 or integrally formed with the main buckle body 21. The lower belt clip 222 is connected to the upper belt clip 221 through a fastening structure. The detachable upper belt clip 221 and lower belt clip 222 facilitate the assembly of the fixing buckle 2 and the timing belt 44. After the upper belt clip 221 and lower belt clip 222 are fastened together, they form a narrow hole 223 for clamping the timing belt 44. The narrow hole 223 is fixed to the timing belt 44 by an interference fit, so as to ensure that the fixing buckle 2 and the timing belt 44 can move synchronously. One possible implementation is that the upper belt clip 221 is provided with a slot 2211 and a positioning pin hole 2212, and the lower belt clip 222 is provided with a buckle 2221 and a positioning pin 2222. The connection method of slot 2211-buckle 2221 provides high connection stability and prevents the lower belt clip 222 from loosening. The connection method of positioning pin hole 2212-positioning pin 2222 provides a convenient detachable position. Furthermore, the pin hole and pin are mated in an interference fit manner, which further improves the stability of the connection.
[0051] In summary, this application provides a push rod structure for realizing a lateral push-pull movable rod, comprising: a driven rod, the outer end of which is orthogonally connected to the end of the movable rod for linkage with the laterally translating movable rod; a fixing buckle connected to the inner end of the driven rod for transmitting push-pull force to cause the driven rod to translate; a motor and a transmission assembly, the transmission assembly being connected to the motor via a clutch and transmitting the torque output by the motor to the fixing buckle; an end box for accommodating the driven rod, the fixing buckle, the motor, and the transmission assembly; and a limiting plug disposed at the lateral end of the end box for preventing the driven rod from disengaging.
