Description

Technical Field

[0001] The utility model relates to the field of fully automatic umbrellas, and particularly relates to a self-opening and self-closing umbrella head that stops as it is retracted. Background Art

[0002] For fully automatic umbrellas, the cumbersome steps of manually opening and closing traditional umbrellas are abandoned. Through a built-in high-precision sensing device or a one-key operation button, the automatic opening and closing of the umbrella are realized. When the user is about to step into the rain, just gently press the button or trigger a specific induction, and the umbrella surface will quickly and smoothly unfold, effectively blocking the wind and rain. Similarly, when reaching the destination or no longer needing the umbrella, with a simple operation again, the umbrella surface will automatically and smoothly retract. The whole process is both fast and elegant, avoiding the inconvenience and embarrassment that may be brought by manual operation.

[0003] Fully automatic umbrellas not only pursue extreme convenience in design, but also take into account the selection of materials and the improvement of technology to ensure their durability and waterproof performance. The umbrella surface made of high-strength waterproof material can effectively resist heavy rain washing and keep the inside dry at the same time; while the strong skeleton design ensures that the umbrella is still stable and reliable in strong wind weather.

[0004] However, when retracting the umbrella surface of the existing automatic umbrella, it is necessary to manually press the middle rod of the umbrella to retract it. During this process, in addition to overcoming the resistance of the middle rod spring, it is also necessary to complete the retraction at one time, so that the middle rod of the umbrella is buckled with the clamping part in the umbrella handle. Otherwise, the middle rod will rebound under the action of the spring without anything to restrict it. The process of retracting the umbrella requires a lot of effort, and there is a hidden danger of injury due to the rapid bouncing of the middle rod during the retraction process.

[0066] Embodiment

[0067] Please refer to Figures 1-13 As shown, this embodiment provides a self-opening and self-closing umbrella head that stops when retracting, including an umbrella head body 1, an inner seat 2, an inner tube 4, and an outer tube assembly 8. The inner seat 2 is built into the umbrella head body 1. The bottom end of the inner tube 4 is fixed to the inner seat 2. The inner tube 4 passes through the umbrella head body 1 and extends upward. The outer tube assembly 8 is sleeved on the inner tube 4 and moves in the extending direction of the inner tube 4. In this embodiment, the outer tube assembly 8 includes an outer tube 81 and a middle tube 82. The middle tube 82 is sleeved on the inner tube 4, and the outer tube 81 is sleeved on the middle tube 82.

[0068] An installation channel 21 is provided on the inner seat 2, and the installation channel 21 communicates with the interior of the inner tube 4. In this embodiment, the installation channel 21 extends in the same direction as the inner tube 4. At the bottom of the installation channel 21 of the inner seat 2, a ratchet assembly 22 is provided. The ratchet assembly 22 includes a ratchet part 221, a winding part 222, and a spring fixing part 223 arranged in sequence. A spiral spring 224 is sleeved on the spring fixing part 223. One end of the spiral spring 224 is fixedly connected to the spring fixing part 223, and the other end of the spiral spring 224 is fixed on the inner seat 2. The retractable umbrella cord 5 is fixedly wound on the winding part 222. The other end of the retractable umbrella cord 5 passes through the installation channel 21 and the inner tube 4 and is fixedly connected to the top end of the outer tube assembly 8. In this embodiment, the other end of the retractable umbrella cord 5 passes through the installation channel 21 and the inner tube 4 and is fixedly connected to the top end of the outer tube 81. A pull cord 10 and an inner buckle 6 are further arranged inside the inner tube 4. One end of the pull cord 10 is fixedly connected to the top end of the inner buckle 6; the other end of the pull cord 10 bypasses the top end of the outer tube assembly 8 and is fixedly connected to an external umbrella rib. In this embodiment, the other end of the pull cord 10 bypasses the top end of the outer tube 81 and is fixedly connected to an external umbrella rib to retract the umbrella rib. In this embodiment, the torque direction of the spiral spring 224 is opposite to the pulling force direction applied to the winding part 222 when the retractable umbrella cord 5 is wound on the winding part 222. The buckle head 61 of the inner buckle 6 protrudes outwards. In this embodiment, the buckle head 61 is located at the bottom of the inner buckle 6. A clamping groove 712 for clamping the buckle head 61 is arranged in the installation channel 21; an elastic transmission member 74 is further arranged in the installation channel 21. The elastic transmission member 74 and the clamping groove 712 are respectively located on both sides of the buckle head 61, and the distance between the elastic transmission member 74 and the clamping groove 712 is less than the width of the buckle head 61.

[0069] On the front and rear side surfaces of the inner seat 2, a button assembly 23 and a swing rod assembly 24 are respectively arranged. The button assembly 23 and the swing rod assembly 24 correspond to the positions of the clamping groove 712 and the elastic transmission member 74 respectively. Inside the button 231, a rocking rod member 232 for pushing the buckle head 61 is arranged; the top end of the swing rod assembly 24 is rotatably arranged on the inner seat 2 through a swing rod shaft 242. A transmission part is arranged in the middle of the swing rod assembly 24. The transmission part is in abutting contact with the elastic transmission member 74, and the bottom end of the swing rod assembly 24 extends to one side of the ratchet part 221.

[0070] A limiting member 25 is arranged inside the button assembly 23. An outwardly protruding limiting convex block 253 is arranged on the limiting member 25. The limiting convex block 253 is inserted on the outer tube assembly 8.

[0071] Please refer to Figures 1-3As shown, in the retracted state, the limiting member 25 limits the outer tube assembly 8, keeping the outer tube assembly 8 stably retracted on the umbrella head body 1; and the buckle 61 is embedded in the engaging groove 712; at the same time, since the distance between the elastic transmission member 74 and the engaging groove 712 is less than the width of the buckle 61, the buckle 61 squeezes the elastic transmission member 74, and the thrust is applied to the swing rod assembly 24 through the transmission part, causing the bottom end of the swing rod assembly 24 to separate from the ratchet part 221. During the downward retraction of the outer tube assembly 8, the swing rod member is pushed downward to swing.

[0072] During the umbrella opening process, the button 231 is pressed, so that the limiting member 25 separates from the outer tube assembly 8, releasing the limiting force on the outer tube assembly 8. Driven by the compression spring 9 inside the inner tube 4, the outer tube assembly 8 moves upward, and at the same time drives the umbrella closing rope 5 to move upward, driving the ratchet assembly 22 to rotate and release the umbrella closing rope 5. During the release of the umbrella closing rope 5, the spiral spring 224 deforms and stores energy. After the button 231 is reset, the swing rod member 232 rebounds and abuts against the buckle 61.

[0073] During the umbrella closing process, the button 231 is pressed, so that the buckle 61 separates from the engaging groove 712. Under the pulling force of the pulling rope 10, the inner buckle 6 leaves the retaining tube 7, and the umbrella ribs are retracted. At the same time, the elastic transmission member 74 rebounds, and the bottom of the swing rod assembly 24 rotates towards the ratchet assembly 22 until the swing rod assembly 24 abuts against the ratchet part 221.

[0074] During the process of retracting the outer tube assembly 8 and the inner tube 4, the deformation of the spiral spring 224 is restored, releasing the torsion force, driving the ratchet assembly 22 to rotate, winding up the umbrella closing rope 5, and the umbrella closing rope 5 pulls the outer tube assembly 8 downward to engage with the limiting convex block 253 of the limiting member 25. At the same time, during the umbrella closing process, the squeezing force of the buckle 61 on the elastic transmission member 74 is removed, the elastic transmission member 74 is reset, and the bottom of the swing rod assembly 24 rotates towards the ratchet assembly 22 until the swing rod assembly 24 abuts against the ratchet part 221, preventing the ratchet assembly 22 from reversing and avoiding the automatic umbrella from rebounding during the umbrella closing process and causing safety accidents.

[0075] By controlling the contact or separation state between the swing rod assembly 24 and the ratchet assembly 22 through the elastic transmission member 74 and the buckle 61, when in the contact state, the ratchet assembly 22 can only rotate in one direction to wind up the umbrella closing rope 5, preventing the ratchet assembly 22 from reversing and causing the automatic umbrella to rebound during the umbrella closing process and preventing safety accidents. At the same time, the deformation torsion force of the spiral spring 224 is used to realize the automatic umbrella closing of the umbrella, avoiding the need to press the umbrella handle forcefully during the umbrella closing process and saving physical strength.

[0076] Please refer to Figures 1-3 and Figures 11-13As shown, specifically, a retaining tube 7 is fixed inside the installation channel 21. In this embodiment, the bottom end of the compression spring 9 abuts against the top surface of the retaining tube 7, and an extension channel 75 is formed in the retaining tube 7. The extension direction of the extension channel 75 is the same as that of the installation channel 21 and is communicated with the inside of the inner tube 4. First notches 71 and second notches 72 are respectively formed on two opposite sides of the retaining tube 7. A blocking block 711 extending relatively is arranged on the side of the first notch 71 to form the above-mentioned engaging groove 712. In this embodiment, the two blocking blocks 711 are spaced apart from each other, and the space between the two blocking blocks 711 is for the swing rod member 232 to pass through when turning up and down.

[0077] The top end of the elastic transmission member 74 is fixed in the second notch 72. Please refer to Figure 3 and Figure 13 As shown, specifically, the elastic transmission member 74 includes a mounting piece 741. The mounting piece 741 is fixed in the second notch 72, and a bent piece 742 is connected to the bottom of the mounting piece 741. The bent piece 742 is bent towards the first notch 71, and a transmission piece 743 is connected to the bottom of the bent piece 742. The bottom end of the transmission piece 743 extends below the transmission part and is connected with a reset piece 744. The reset piece 744 is bent towards the side of the second notch 72, and a reset bent part 7441 is arranged at the bottom end of the reset piece 744. The reset bent part 7441 abuts against the inner side wall of the retaining tube 7. The bent piece 742 increases the bending degree of the elastic transmission member 74, thereby improving the softness and elasticity of the elastic bending member. The relatively long transmission piece 743 is provided to ensure that the transmission piece 743 extends below the transmission part of the swing rod assembly 24, and completely transmits the extrusion force received by the elastic transmission member 74 to the swing rod assembly 24, effectively driving the swing rod assembly 24 to turn. The reset bent part 7441 of the reset piece 744 abuts against the inner side wall of the retaining tube 7, providing a reverse reset force for the elastic transmission member 74, driving the elastic transmission member 74 to reset when the buckle 61 moves upward. The reset bent part 7441 forms an arc surface to contact the inner side wall of the retaining tube 7, reducing the friction between the two and reducing the wear speed of the elastic transmission member 74 on the retaining tube 7.

[0078] Please refer to Figure 12 As shown, further, a relief channel 73 is also formed on the outer side of the retaining tube 7. The relief channel 73 extends along the length direction of the retaining tube 7, and the umbrella closing rope 5 passes through the relief channel 73 and extends upward. The relief channel 73 is for the umbrella closing rope 5 to pass through, protecting the umbrella closing rope 5 and preventing the umbrella closing rope 5 from colliding with other structures during the upward or downward movement, affecting the opening and closing process.

[0079] Please refer to Figure 6 and Figure 7As shown, specifically, a plurality of ratchet teeth 2211 are arranged at intervals on the ratchet portion 221, and the outer top surface of the ratchet teeth 2211 is an arc-shaped curved surface 2212. The arc surface reduces the overall weight of the ratchet portion 221, and during the rope winding process, it reduces the travel path length of the bottom end of the swing rod assembly 24, reduces the resistance applied by the swing rod assembly 24 to the ratchet portion 221, and improves the rope winding efficiency.

[0080] Furthermore, a knot fixing groove 2221 is formed on the winding portion 222, one end of the umbrella closing rope 5 is fixed in the knot fixing groove 2221, and a baffle 2222 is arranged on one side of the winding portion 222 close to the spring fixing portion 223. The baffle 2222 and the ratchet teeth 2211 limit the umbrella closing rope 5 from both sides to ensure the accuracy of the winding position of the umbrella closing rope 5.

[0081] Furthermore, the shape of the spring fixing portion 223 is a cylinder, a spring fixing groove 2231 is formed on the spring fixing portion 223, and one end of the spiral spring 224 is fixed in the spring fixing groove 2231. A circular shaft 225 is fixedly arranged at the center of the side surface of the ratchet portion 221 far from the winding portion 222, and the ratchet assembly 22 is rotatably arranged at the bottom end of the inner seat 2 through the circular shaft 225 and the spring fixing portion 223.

[0082] In this embodiment, a ratchet groove 30 is formed at the bottom end of the inner seat 2 located in the installation channel 21, the ratchet assembly 22 is rotatably arranged in the ratchet groove 30 through the circular shaft 225 and the spring fixing portion 223, and a spring installation groove 301 is formed on the inner seat 2, and the other end of the spring is fixed in the spring installation groove 301.

[0083] Please refer to Figure 10 As shown, specifically, the limiting member 25 includes a limiting body 251 and connecting arms 252 arranged at both ends on one side of the limiting body 251. The connecting arms 252 extend towards the button assembly 23 and are in abutting contact with the button assembly 23. A limiting convex block 253 is arranged on the limiting body 251 and is located between the two connecting arms 252. The two connecting arms 252 and the limiting body 251 form a U-shaped limiting member 25 to make way for the outer tube assembly 8, and the outer tube assembly 8 is limited by the limiting convex block 253 arranged on the inner side, which has a good limiting effect on the premise of not affecting the movement stroke of the outer tube assembly 8.

[0084] Please refer to Figure 4 and Figure 10As shown in the figure, a limiting groove 26 is formed in the inner seat 2. The extending direction of the limiting groove 26 is perpendicular to the extending direction of the installation channel 21, and the limiting groove 26 communicates with the installation channel 21. The limiting body 251 is embedded in the limiting groove 26. A limiting spring 261 is arranged at the bottom of the limiting groove 26, and the limiting spring 261 abuts against the other side surface of the limiting body 251. The limiting spring 261 applies a thrust force to the limiting body 251 towards the outer tube assembly 8 to ensure the stability of the insertion between the limiting bump 253 and the outer tube assembly 8. When the parachute is opened, the button assembly 23 is pressed. The button assembly 23 transmits a force towards the limiting spring 261 to the limiting body 251 through the connecting arm 252. The limiting body 251 compresses the limiting spring 261, so that the limiting protrusion is separated from the outer tube assembly 8, and the limiting force on the outer tube assembly 8 is released.
