Description

Technical Field

[0001] This invention relates to the field of umbrella technology, specifically to an outward-folding carbon fiber umbrella rib. Background Technology

[0002] Umbrellas are a common household item. Using an umbrella on rainy days effectively prevents people from getting wet, and the UV-protective coating on the umbrella surface can also prevent sunburn, bringing great convenience to people's travels. Most umbrellas on the market have metal frames, which are prone to rusting when wet, and metal frames are also relatively heavy and easily deformed. Therefore, umbrellas with carbon fiber ribs have emerged on the market. These are not only lightweight but also resistant to rust and deformation.

[0003] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: when the umbrella is opened, if it is pushed upwards with too much force, the umbrella canopy can be easily opened rapidly by the umbrella frame due to excessive thrust. The weight of the umbrella canopy will be applied to the umbrella frame, which can easily cause the umbrella frame to bend during the process of opening with too much force, thus affecting the lifespan of the umbrella. In addition, water droplets will remain on the umbrella during the closing process, making the umbrella damp and affecting its performance. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing an outward-folding carbon fiber umbrella rib structure that can reduce the impact force when opening, prevent the umbrella ribs on the frame from easily bending and deforming, and reduce water droplet residue on the umbrella fabric.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an outward-folding carbon fiber umbrella rib, including an umbrella pole (1), a bottom frame (2) set at the upper end of the umbrella pole (1) for twisting deformation, a top frame (3) set at the top of the umbrella pole (1) for providing rigid support, the top of the middle section of the bottom frame (2) and the bottom of the middle section of the top frame (3) are movably engaged, characterized in that: the bottom frame (2) includes a foldable movable rod (31), the movable rod (31) includes a fixed rod (A) and a moving rod (B), a movable block (32) embedded between the fixed rod (B) and the moving rod (A) for enabling the movable rod (31) to twist and produce a braking effect and a shaking effect, and a engaging block (33) fixedly set on the top surface of the movable rod (31) for movably engaging with the top frame (3).

[0006] A further improvement is that the movable block (32) includes a torsion ring (321) fixedly connected to one end of the moving rod (A), a movable groove (322) embedded inside the torsion ring (321) to provide a space for movement, an elastic element with one end set on the inner wall of the movable groove (322) for absorbing impact, a movable column (324) with one side of its top set on the other end of the elastic element and its top end in contact with the inner wall of the movable groove (322) for compressing the elastic element, and a rotating block (325) set at the center of the torsion ring (321) and whose outer wall is fixedly connected to the bottom of the movable column (324) for generating vibration. The rotating block (325) is connected to the fixed rod (B), and the movable block (32) is provided with a shaking device for making the movable block (32) shake.

[0007] A further improvement is that the shaking device includes a contact block (A2), which is located on the inner wall of the top of the movable groove (322). The movable column (324) collides with the contact block (A2) to make the movable block (32) shake.

[0008] A further improvement is that the contact block (A2) includes a conductive shell (A21) connected to the inner wall of the movable groove (322) for transmitting vibration, a flexible sheet (A22) whose top surface is embedded in the bottom surface of the conductive shell (A21) and can be deformed by impact, a conductive frame (A23) for transmitting vibration that is fixedly connected to the inner wall of the conductive shell (A21) at both ends and the top surface, and a toggle rod (A24) whose top is embedded in the bottom surface of the middle section of the conductive frame (A23). When the movable column (324) slides in the movable groove (322), it collides with the toggle rod (A24) to generate vibration.

[0009] A further improvement is that the actuating lever (A24) includes a guide rod (B1) for embedding into the guide frame (A23), a contact rod (B2) whose top end is movably engaged with the bottom end of the guide rod (B1) for generating vibration upon impact, a rebound ring (B3) embedded in the inner wall of the contact rod (B2), an impact ball (B4) disposed in the inner wall of the contact rod (B2) and freely movable, and an impact block (B5) embedded in the inner wall of the contact rod (B2) for generating vibration by colliding with the impact ball (B4).

[0010] A further improvement is that: the movable column (324), the elastic element, and the movable groove (322) are all provided in six parts. The six movable columns (324) are evenly distributed in a ring on the outer wall of the torsion ring (321), and the six movable grooves (322) are evenly distributed in a ring inside the torsion ring (321). The inner wall of the six movable grooves (322) and one side of the top of the six movable columns (324) are connected by six elastic elements.

[0011] A further improvement is that the top of the movable column (324) is provided with two rotating wheels, which resist collision with the actuating lever (A24).

[0012] A further improvement is that the elastic element is a compression spring.

[0013] A further improvement is that the umbrella pole (1), bottom frame (2) and top frame (3) are made of carbon fiber.

[0014] After adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0015] When the umbrella is pushed upwards with great force, the present invention can absorb the excessive thrust through the compression spring, thereby achieving a braking effect when pushing upwards. This prevents the umbrella ribs of the bottom and top frames from bending due to the umbrella opening too quickly, thus increasing the service life of the umbrella ribs and ultimately extending the service life of the umbrella.

[0016] When the umbrella is opened, the movable block on the bottom frame compresses the spring and generates elastic force when it expands. When the umbrella is closed, the elastic force is released to accelerate the closing speed. Raindrops are then thrown out by inertia. At the same time, the twisting causes the contact hammer to collide with the contact block, which generates vibration and causes the water droplets to slide further off the umbrella surface, thereby reducing the amount of water droplets remaining on the umbrella surface.

Implementation

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figure 1-5 As shown, the technical solution adopted in this specific embodiment is: an outward-folding carbon fiber umbrella rib, including an umbrella pole 1 made of carbon fiber material for the user to hold, and a bottom frame (2) set at the upper end of the umbrella pole (1) for twisting and deformation. The bottom frame (2) is made of carbon fiber material. A sliding sleeve that can slide freely is provided on the top outer wall of the umbrella pole 1, and the umbrella pole 1 is connected to the bottom frame 2 through the sliding sleeve. A top frame 3 made of carbon fiber material is provided at the top of the umbrella pole 1. The bottom of the top frame 3 is connected to the middle section of the bottom frame 2. The bottom frame 2 includes a foldable movable rod 31, which includes a fixed rod B and a moving rod A. A movable block 32 is embedded between the fixed rod B and the moving rod A to allow the movable rod 31 to twist and produce a braking and shaking effect. A locking block 33 is fixedly set on the top surface of the movable rod 31 for movably engaging with the top frame 2. Both the top frame 3 and the bottom frame 2 are provided with three or more. Multiple top frames 3 and bottom frames 2 can improve the overall rigidity of the umbrella ribs. In this embodiment, there are six top frames 3 and bottom frames 2.

[0026] The movable block 32 includes a torsion ring 321 fixedly connected to one end of the moving rod A on the outer layer. The torsion ring 321 has a movable groove 322 embedded inside to provide movement space. A compression spring 323 is set on the inner wall of the movable groove 322 to absorb impact. A movable column 324 is set on the other end of the compression spring 323 and its top side is in contact with the inner wall of the movable groove 322 to compress the compression spring 323. A rotating block 325 is set at the center of the torsion ring 321 and its outer wall is fixedly connected to the bottom of the movable column 324 to generate vibration. The rotating block 325 is connected to the fixed rod B. When the umbrella is opened with great force, the movable rod 31 will suddenly open and generate a sudden twist, which will cause the torsion ring 321 to twist at the same time, causing the compression spring 323 and the movable column 324 to generate relative displacement. The compression spring 323 absorbs the excessive torque and brakes, thereby preventing the movable rod 31 from being deformed by too sudden torque.

[0027] In this embodiment, there are six movable columns 324, six compression springs 323, and six movable grooves 322. The six movable columns 324 are evenly distributed in a ring on the outer wall of the torsion ring 321, and the six movable grooves 322 are evenly distributed in a ring inside the torsion ring 321. The inner wall of the six movable grooves 322 is connected to one side of the top of the six movable columns 324 by six compression springs 323, which can expand the maximum torque absorption value and thus enhance the braking effect.

[0028] In order to shake off the rainwater on the umbrella surface and further increase the braking effect, a contact block (A2) is also included. The contact block (A2) is located on the inner wall of the top of the movable groove (322). The movable column (324) collides with the contact block (A2) to make the movable block (32) vibrate.

[0029] Specifically, the contact block A2 includes a conductive shell A21 connected to the inner wall of the outer ring shell A1 for transmitting vibration, a flexible sheet A22 that can be deformed by impact and embedded in the bottom surface of the conductive shell A21, a conductive frame A23 for transmitting vibration that is fixedly connected to the inner wall of the conductive shell A21 at both ends and the top surface, and a toggle rod A24 whose top is embedded in the bottom surface of the middle section of the conductive frame A23. When the movable column (324) slides in the movable groove (322), it collides with the toggle rod (A24) to generate vibration. The toggle rod A24 can output the vibration generated when it contacts the movable column (324) to the conductive frame A23, and the vibration is output outward through the conductive frame A23 to spread it, thereby generating a dense vibration effect, and the resistance during contact is reduced by the deformation of the flexible sheet A22.

[0030] The actuating lever A24 includes a guide rod B1 for embedding into the guide frame A23, a contact rod B2 whose top end engages with the bottom end of the guide rod B1 to generate vibration upon impact, a rebound ring B3 embedded in the inner wall of the contact rod B2, the rebound ring B3 being made of elastic rubber material and being a hollow ring, an impact ball B4 disposed in the inner wall of the contact rod B2 and freely movable, and an impact block B5 embedded in the inner wall of the contact rod B2 for colliding with the impact ball B4 to generate vibration. When an impact occurs, the contact rod B2 is impacted, thereby generating vibration and shaking, which in turn causes the internal impact ball B4 to be flung and move freely, allowing it to further contact the impact block B5 to generate more vibration.

[0031] In order to enable the movable column 324 to better impact and actuate the lever (A24), two rotating wheels are provided on the top of the movable column (324), and the rotating wheels resist the impact with the lever (A24).

[0032] The working principle of this invention is as follows: When opening the umbrella, pushing the bottom frame 2 upwards expands it from a closed state, simultaneously causing the top frame 3 to expand, opening the umbrella surface 5. During this opening, the movable rod 31 on the bottom frame 2 twists, which in turn causes the movable block 32 to twist. The outer torsion ring 321 of the movable block 32 also twists. When forcefully opening the umbrella, the movable rod 31 suddenly expands, causing a sudden twist, which in turn causes the torsion ring 321 to twist simultaneously. This results in relative displacement between the compression spring 323 and the movable column 324. The compression spring 323 absorbs excessive torque for braking, thus preventing the movable rod 31 from deforming due to excessive sudden torque and ensuring the lifespan of the reverse umbrella. When closing the umbrella, pulling down the bottom frame 2 from an expanded state simultaneously causes the top frame to close, closing the umbrella surface 5. When the movable block 32 expands, it causes the torsion ring 321 to twist. At this time, the compression spring 323 is squeezed and generates elastic force. When closing, the elastic force is released to accelerate the closing speed. At the same time, the movable column 324 quickly contacts the contact block A2. The bottom of the contact block A2 is equipped with a toggle rod A24. After being impacted, it generates vibration and transmits the vibration upward through the transmission rod B1. It is output to the transmission frame A23 and further output to the transmission shell A21, thus allowing the vibration to spread to the entire umbrella surface. After contacting the movable column 324, the toggle rod A24 swings, which causes the built-in impact ball B4 to move freely on the inner wall of the contact rod B2. After being rebounded by the rebound ring B3, it repeatedly contacts the impact block B5, thereby generating more slight vibrations. In the process of closing the reverse umbrella, a large amount of vibration is generated to further shake off the water droplets.
