Description

Technical Field

[0001] This utility model relates to the field of umbrella design and manufacturing, and in particular to an automatic opening and closing umbrella that prevents accidental activation. Background Technology

[0002] As an ancient portable tool for sun and rain protection, the umbrella's basic structure includes the canopy, the ribs supporting the canopy, and the umbrella pole and opening / closing mechanism that connect the ribs and control its opening and closing. With technological advancements, automatic umbrellas have emerged to improve ease of use. These umbrellas, through built-in energy storage and release mechanisms, replace the traditional manual pushing and pulling action, allowing users to quickly and automatically open or close the canopy with the touch of a button, thus improving operational efficiency and user experience.

[0003] Currently, the mainstream automatic umbrellas on the market are mainly divided into two categories based on their driving method: spring-driven automatic umbrellas and electric-driven automatic umbrellas. Common spring-driven automatic umbrellas rely on powerful compression or tension springs pre-installed inside the umbrella shaft or at key points. When the umbrella is opened, pressing the open button releases the energy stored in the spring, propelling the umbrella ribs to unfold rapidly. Similarly, when closing the umbrella, the user needs to overcome the spring resistance to close and lock it in place. Electric-driven automatic umbrellas typically incorporate a small motor, reduction gear set, battery, and control circuitry. When the user presses the open or close button, the control circuit activates the motor, which drives the push rod or rotating parts inside the umbrella shaft via a gear transmission mechanism, thus achieving smooth and automatic opening or closing of the umbrella.

[0004] However, both spring-driven and electrically driven automatic umbrellas rely heavily on one or more physical buttons as trigger switches for operation. This design has a significant inherent flaw in practical use: accidental button activation is the most common and troublesome problem. Since the opening and closing buttons are usually located in easily accessible positions on the umbrella handle, when the umbrella is carelessly placed in a backpack, handbag, car, or other confined space, it is easily subjected to pressure, impacts from external objects, or its own weight, causing the button to be accidentally pressed. Once the opening button is accidentally pressed, the umbrella will forcefully open in the confined space, potentially damaging the umbrella itself and crushing surrounding objects. Utility Model Content

[0005] To overcome the drawback of being prone to accidental activation, this invention provides an automatic opening and closing umbrella designed to prevent accidental activation, thus addressing the aforementioned shortcomings.

[0006] An automatic opening and closing umbrella designed to prevent accidental activation includes an umbrella body and a handle. The handle is connected to the bottom of the umbrella body and also includes a rotary switch and a torsion spring. The rotary switch is rotatably connected to the end of the handle. A power component for driving the opening and closing of the umbrella body and a power supply are disposed inside the handle. The rotary switch is wired to the power component. The torsion spring is sleeved on the rotary switch. One end of the torsion spring is connected to the rotary switch, and the other end is connected to the handle. A limit groove is formed at the lower end of the rotary switch. An anti-accidental activation component for limiting the rotation of the rotary switch is disposed inside the handle.

[0007] As a preferred technical solution of this utility model, the anti-accidental touch component includes a button, which is slidably connected to the umbrella handle. The upper end of the button is slidably connected to the limiting groove. The button is limited and cooperated with the rotary switch through the limiting groove. A first spring is provided in the umbrella handle. One end of the first spring is connected to the button, and the other end is connected to the umbrella handle.

[0008] As a preferred embodiment of this utility model, an "L"-shaped sealing strip is provided on the inner side and top of the umbrella handle. The sealing strip is located between the umbrella handle and the rotary switch. A second spring is provided at the upper end of the umbrella handle. One end of the second spring is connected to the umbrella handle, and the other end is connected to the sealing strip.

[0009] As a preferred embodiment of this utility model, the button is inserted into the umbrella handle end and connected to a top block, the bottom end of the sealing strip is connected to a pull plate, the pull plate is provided with an inclined surface, and the top block and the inclined surface of the pull plate are pressed together.

[0010] As a preferred embodiment of this utility model, the outer ring of the rotary switch is provided with an anti-slip sleeve, and the anti-slip sleeve is provided with longitudinal stripes.

[0011] As a preferred embodiment of this utility model, the outer ring of the umbrella handle is provided with an insulating sleeve, and the insulating sleeve is provided with a plurality of annular grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By setting the button to slide into the limit groove at the lower end of the rotary switch, the button is inserted into the limit groove in the normal state to form a mechanical interlock. Users must actively press the button to release the lock on the rotary switch, which significantly improves the safety and reliability of use and achieves the purpose of preventing accidental opening of the umbrella.

[0014] 2. Under the continuous pressure of the second spring, the sealing strip tightly adheres to the bottom of the rotary switch, forming a dynamic sealing interface. The top block moves with the button and is pressed against the inclined surface of the pull plate, causing the top of the sealing strip to temporarily detach from the rotary switch, ensuring dustproof and waterproof performance while optimizing the difficulty of operation.

[0015] 3. By setting an anti-slip sleeve with longitudinal stripes on the outer ring of the rotary switch, the switch can be turned steadily even in rainy weather or when hands are wet; an insulating sleeve with annular grooves on the outer ring of the umbrella handle optimizes grip comfort, anti-slip properties, and insulation safety.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0021] Example: An automatic opening and closing umbrella designed to prevent accidental activation, such as... Figures 1-3 As shown, the umbrella includes an umbrella body 1 and an umbrella handle 2. The umbrella body 1 is connected to the bottom of the umbrella handle 2. The umbrella body 1 also includes a rotary switch 3 and a torsion spring 4. The rotary switch 3 is rotatably connected to the end of the umbrella handle 2. The umbrella handle 2 contains a power component that drives the umbrella body 1 to open and close, as well as a power supply. The rotary switch 3 is wired to the power component. The rotary switch 3 is fitted with a torsion spring 4. One end of the torsion spring 4 is connected to the rotary switch 3, and the other end is connected to the umbrella handle 2. The lower end of the rotary switch 3 has a limit groove 5. The umbrella handle 2 contains an anti-accidental touch component to limit the rotation of the rotary switch 3. The rotary switch 3 is connected to the end of the umbrella handle 2 through the torsion spring 4. The rotary switch has the effect of preventing accidental touch.

[0022] like Figure 2 and Figure 3 As shown, the anti-accidental touch component includes a button 6 and a first spring 7. The button 6 is slidably connected inside the umbrella handle 2, and the upper end of the button 6 is slidably connected inside the limiting groove 5. The button 6 is limited and engaged with the rotary switch 3 through the limiting groove 5. The first spring 7 is provided inside the umbrella handle 2. One end of the first spring 7 is connected to the button 6, and the other end is connected to the umbrella handle 2. The button 6 is inserted into the limiting groove 5 to physically lock the rotary switch 3, preventing it from rotating accidentally, thus further optimizing the anti-accidental touch effect.

[0023] like Figure 2As shown, it also includes a second spring 10 and a sealing strip 11. An "L"-shaped sealing strip 11 is provided on the inner side and top of the umbrella handle 2. The sealing strip 11 is located between the umbrella handle 2 and the rotary switch 3. A second spring 10 is provided at the upper end of the umbrella handle 2. One end of the second spring 10 is connected to the umbrella handle 2, and the other end is connected to the sealing strip 11.

[0024] like Figure 2 As shown, it also includes a top block 8 and a pull plate 9. The button 6 is located at the end of the umbrella handle 2 and is connected to the top block 8. The bottom end of the sealing strip 11 is connected to the pull plate 9. The pull plate 9 is provided with an inclined surface, and the top block 8 and the inclined surface of the pull plate 9 are pressed together.

[0025] like Figure 2 As shown, it also includes an anti-slip sleeve 12. The outer ring of the rotary switch 3 is fitted with an anti-slip sleeve 12, and the anti-slip sleeve 12 is provided with longitudinal stripes.

[0026] like Figure 2 As shown, it also includes an insulating sleeve 13. The outer ring of the umbrella handle 2 is fitted with an insulating sleeve 13, and the insulating sleeve 13 is provided with several annular grooves.

[0027] When the user needs to use the umbrella, they hold the umbrella handle 2 with one hand and press button 6 with their thumb. After being pressed, button 6 overcomes the resistance of the first spring 7 and slides inwards into the umbrella handle 2, compressing the first spring 7 and storing potential energy in the process. As button 6 moves inwards, its tip gradually slides out of the limiting groove 5 at the lower end of the rotary switch 3, thus releasing the mechanical lock on the rotation of the rotary switch 3. At this time, the user rotates the rotary switch 3 with their other hand. When the rotary switch 3 rotates inside the umbrella handle 2, it twists the torsion spring 4 fitted on it, causing the torsion spring 4 to accumulate elastic potential energy. The rotation direction of the rotary switch 3 is set as the trigger command: turning it to the right activates the power component to open the umbrella, and turning it to the left closes the umbrella. The power component then continuously drives the umbrella body 1 to complete the opening action. After the opening action is completed, the user releases the rotary switch 3, and the torsion spring 4 drives the rotary switch 3 to automatically return to its initial position. Simultaneously, when the user releases their finger from button 6, the compressed first spring 7 pushes button 6 to slide back into and lock into the limiting groove 5 of rotary switch 3, thus ending the umbrella opening process. Closing the umbrella is similar; the user must first press button 6 to release the lock of rotary switch 3, then turn rotary switch 3 to the left to trigger the power unit to execute the umbrella closing command. After closing the umbrella, releasing rotary switch 3 and button 6 causes them to automatically reset. The portable power source inside the umbrella handle 2 powers the power unit and can be replaced or recharged.

[0028] Before the rotary switch 3 needs to be turned, the sealing strip 11, under the continuous pressure of the second spring 10, has its "L"-shaped top tightly fitted against the joint between the rotary switch 3 and the umbrella handle 2, ensuring good sealing and preventing rainwater or dust from entering. When the user presses button 6 to unlock, the top block 8 connected to the bottom of button 6 also moves, contacting the pre-set inclined surface of pull plate 9. Guided by the inclined surface, the top block 8 transmits a downward force to pull plate 9. Pull plate 9, under the force, causes the sealing strip 11 connected to it to overcome the elastic force of the second spring 10 and slide down a short distance along the inside of umbrella handle 2. The direct result of the downward movement of sealing strip 11 is that its top end disengages from the bottom of rotary switch 3, eliminating the static friction between them. This significantly reduces the force required for the user to turn the rotary switch 3, making operation easier. When the user releases button 6, button 6 resets under the action of the first spring 7, and the top block 8 also leaves the inclined surface of pull plate 9. At this time, the compressed second spring 10 loses its constraint, and its stored potential energy is released, pushing the sealing strip 11 to slide upward and reset. Its top end then tightly adheres to the bottom of the rotary switch 3, restoring the sealing state.

[0029] The rotary switch 3 is fitted with an anti-slip sleeve 12 on its outer ring. The longitudinal stripes on its surface effectively increase the coefficient of friction between the user's fingers and the knob, ensuring stable force application and preventing slippage even in rainy weather or when hands are wet. The insulating sleeve 13 fitted around the umbrella handle 2 has several annular grooves on its surface, optimizing the comfort and stability of the user's grip on the umbrella handle 2 and providing a better feel. In addition, an indicator sticker is affixed to the top area of ​​the insulating sleeve 13, clearly indicating the opening and closing functions of the umbrella according to the left and right rotation directions of the rotary switch 3. This allows users to intuitively understand the operation method upon first use, reducing the learning curve.

[0030] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
