Description

Technical Field

[0001] The utility model relates to the technical field of umbrella production, in particular to an umbrella cover accelerated storage mechanism and a folding umbrella. Background Art

[0002] At present, most umbrella covers are separated from umbrellas, so the umbrella covers are easy to lose. In addition, it is difficult to put the umbrella cover inside the umbrella cover during the installation process of the umbrella cover. The umbrella needs to be shaped to be smaller than the area of ​​the opening end of the umbrella cover, and then forcefully loaded. The whole installation process is time-consuming and laborious.

[0003] In order to solve the problem of loss, a technical solution of installing the umbrella cover on the umbrella head or umbrella handle has emerged. For example, the Chinese invention patent, announcement number: CN104473394A, title: an umbrella cover storage device for a folding umbrella, which uses a pull rope to pull the umbrella cover upward. Although storage is achieved, the structure is too complicated, and a space for placing the pull rope is required, which results in a large volume of the entire storage device and poor overall aesthetics. More importantly, when the pull rope pulls the umbrella cover to move, one end of the umbrella cover opening is pulled first. During the movement, the middle part of the umbrella cover is prone to folding and stacking, which interferes with the umbrella body and is difficult to store smoothly. Moreover, the umbrella cover of this method passes through multiple curved spaces, making it extremely difficult to store the umbrella cover smoothly. Alternatively, an umbrella cover insertion structure is built into the umbrella handle (i.e., the handle), but this method is very inconvenient to use, especially when it is difficult to hold, take out, and store normally during storage.

[0004] Moreover, the driving component used to drive the pull rope to pull the umbrella cover to move in the above structure is limited by aesthetics, and its diameter should not be too large. Therefore, it needs to be rotated dozens of times to achieve storage, which is very inconvenient to use and the experience is poor.

[0005] In summary, the existing umbrella cover storage assembly still needs to be further improved. Utility Model Content

[0006] The utility model discloses an umbrella cover accelerating storage mechanism, which has a simple structure and is convenient to operate, and aims to improve the problem of inconvenient operation of the existing umbrella cover storage device.

[0007] The utility model adopts the following scheme:

[0008] A parachute cover acceleration storage mechanism, comprising a base for fixing to the top end of an umbrella body and / or an umbrella handle end and a winding assembly rotatably arranged on the base, a containing space for accommodating the parachute cover is formed between the base and the winding assembly, and the end of the parachute cover away from the opening is fixed to the winding assembly; wherein the winding assembly comprises a driving member, a winding member and an accelerating structure, the winding member is adaptively connected to the accelerating structure, and the driving member is driven to rotate in an operative manner, so as to link the accelerating structure to drive the winding member to rotate at a speed higher than that of the driving member, thereby driving the parachute cover to be quickly wound into the containing space along the axial direction of the parachute body.

[0009] As a further improvement, the acceleration structure includes a ring gear installed or formed on the winding member, at least one star gear meshing with the ring gear, and a sun gear concentrically arranged with the ring gear and meshing with the star gear, the sun gear is fixed to the base via a main shaft, and the rotating shaft of the star gear is installed or molded on the driving member.

[0010] As a further improvement, the main shaft passes through the centers of the driving member, the sun gear and the winding member in sequence, and is coaxially connected to the base, wherein the main shaft includes a limiting portion, a positioning portion and a connecting portion, the limiting portion is sleeved in the limiting hole of the driving member, the positioning portion is connected to the sun gear and is used to limit the rotation of the sun gear, and the connecting portion is used to be fixed to the base.

[0011] As a further improvement, the main shaft is in the shape of a stepped shaft, the outer diameters of the limiting portion, the positioning portion and the connecting portion decrease successively, the positioning portion is configured as a spline or a key, and the connecting portion is configured as a thread.

[0012] As a further improvement, three star gears are distributed in an array along the circumferential direction of the sun gear, and the diameter of each star gear is smaller than the diameter of the sun gear.

[0013] As a further improvement, the driving member is in the shape of a cover to cover the base and the winding assembly, and a force-applying portion is formed by a protrusion or a recess on the outer peripheral surface of the driving member.

[0014] As a further improvement, a clamping portion is provided at one end of the winding member away from the gear ring, and the clamping portion is used to engage with a limiting groove on the base to limit the winding member along its axial direction.

[0015] As a further improvement, the base is provided with a mounting portion for connecting to the main shaft at one end and an assembly portion for connecting to the umbrella body at the other end, and a boss is extended outward from the middle of the base, wherein the periphery of the boss cooperates with the bottom of the driving member to form a clamping channel entering the accommodating space.

[0016] As a further improvement, the umbrella cover is provided with a resistance member near the opening for acting on the periphery of the umbrella body, and the resistance member is configured as a friction surface or an elastic ring.

[0017] A folding umbrella is also provided, comprising an umbrella body, an umbrella cover and an umbrella cover acceleration storage mechanism as described in any of the above items, wherein the storage mechanism is installed at the top end of the umbrella body and / or the umbrella handle end through the base, and the winding assembly is fixed to one end of the umbrella cover. By rotating the driving member, the acceleration structure is linked to drive the winding member to accelerate rotation, so that the umbrella cover is quickly rolled up in the storage mechanism along the axial direction of the umbrella body.

[0018] By adopting the above technical solution, the utility model can achieve the following technical effects:

[0019] 1. The installation position of the storage mechanism is flexible and can be adapted to different umbrella body appearances, thereby presenting different appearance design effects. For example, when the storage mechanism is configured at the end of the umbrella handle, the periphery of the driving member can be adapted to the shape of the umbrella handle to ensure aesthetics. In addition, the storage mechanism is small in size, and the height can be 6-12mm, which has no effect on the appearance of the folding umbrella. At the same time, in the application, an acceleration structure is provided to achieve accelerated rotation of the winding member, thereby facilitating user operation and increasing the frequency of use of the umbrella cover. It is easy to understand that when the driving member of the present application rotates one circle, the winding member can rotate multiple circles under the action of the acceleration structure, thereby reducing the number of circles rotated by the user, speeding up the storage speed of the umbrella cover, shortening the user's operation time, and improving the user experience.

[0020] 2. The sun gear is fixed, the driving part (i.e. the planetary carrier) is the input end, and the ring gear is the output end. The transmission ratio is between 0.6 and 0.8. The structure of the planetary gear can ensure that the transmission process is smooth and reliable, and a stable speed increase can be achieved.

[0021] 3. The storage mechanism has a simple structure and few parts, which can save production costs.

[0022] 4. The driving member is in the shape of a cover to cover the base and the winding assembly, so as to make the storage mechanism look neat and tidy, improve the aesthetics of the storage mechanism, and facilitate the adaptation of the storage mechanism to the appearance of the umbrella body.

[0023] 5. The driving member is provided with an arcuate surface for contacting with the umbrella cover, and the arcuate surface is frictionally matched with the outer surface of the umbrella cover. The driving member can be a plastic part, and the arcuate surface can be a rounded corner set at the contact position through injection molding. The roughness of the arcuate surface is increased by making textures on the injection mold, thereby increasing the friction between the arcuate surface and the outer surface of the umbrella cover. At the same time, the setting of the arcuate surface can avoid the problem of sharp corners puncturing or scratching the umbrella cover, resulting in damage to the umbrella cover.

[0024] 6. The umbrella cover is provided with a resistance member near the opening to act on the outer periphery of the umbrella body, and the resistance member is configured as a friction surface or an elastic ring. By providing the resistance member, the umbrella cover can remain in the inserted state after being inserted into the umbrella cover, and is not easy to fold. At the same time, the resistance member can increase the resistance of the umbrella cover during displacement, so that one end of the umbrella cover can be spirally stored, and the other end forms resistance, ensuring that the middle part of the umbrella cover is not easy to loosen during the storage process, and realizing the smooth spiral ascent or descent process.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0042] Example

[0043] Combination Figures 1 to 11 The present embodiment provides an umbrella cover accelerating storage mechanism, comprising a base 21 for fixing to the top end and / or the handle end 11 of the umbrella body 1 and a winding assembly rotatably arranged on the base 21. Specifically, a receiving space 2A for accommodating the umbrella cover 3 is formed between the base 21 and the winding assembly, and the end of the umbrella cover 3 away from the opening is fixed to the winding assembly; wherein the winding assembly comprises a driving member 22, a winding member 23 and an accelerating structure, wherein the winding member 23 is adaptively connected to the accelerating structure, and the driving member 22 is driven to rotate in an operable manner, and the winding member 23 is driven to rotate at a speed higher than the driving member 22 by the linkage accelerating structure, thereby driving the umbrella cover 3 to be quickly wound into the receiving space 2A along the axial direction of the umbrella body 1.

[0044] Exemplarily, when the storage mechanism 2 is installed at the top of the umbrella body 1, after the user folds the umbrella body 1, the umbrella cover 3 is pulled along the opening of the umbrella cover 3 so that the umbrella cover 3 is inserted downward from the top of the umbrella body 1. In this process, the user does not need to fix the umbrella cover 3 and the umbrella body 1 by hand at the same time, and can directly pull down the umbrella cover 3, which is convenient for the user to operate. When the user needs to store the umbrella cover 3, the umbrella cover 3 can be spirally raised along the axial direction of the umbrella body 1 and rolled up in the accommodating space 2A by turning the driving member 22 by hand. Similarly, when the umbrella cover 3 storage mechanism 2 is installed at the umbrella handle end 11 of the umbrella body 1, after the user folds the umbrella body 1, the umbrella cover 3 is pulled along the opening of the umbrella cover 3 so that the umbrella cover 3 is inserted upward from the umbrella handle; when the user needs to store the umbrella cover 3, the driving member 22 can be turned by hand so that the umbrella cover 3 can be spirally lowered along the axial direction of the umbrella body 1. Of course, the umbrella cover 3 can also be configured as two parts, and a storage mechanism 2 can be provided at the top of the umbrella body 1 and the handle end 11 respectively. The provision of two storage mechanisms 2 can reduce the accommodating space 2A, thereby reducing the volume of the storage mechanism 2.

[0045] It should be noted that, in this embodiment, the installation position of the storage mechanism 2 is flexible and can be adapted to different appearances of the umbrella body 1, thereby presenting different appearance design effects. For example, when the storage mechanism 2 is arranged at the umbrella handle end 11, the periphery of the driving member 22 can be adapted to the shape of the umbrella handle to ensure aesthetics. In addition, the storage mechanism 2 is small in size and the height can be 6-12 mm, which has no effect on the appearance of the folding umbrella. At the same time, in this embodiment, by setting an acceleration structure, the accelerated rotation of the winding member 23 is achieved, thereby facilitating user operation and increasing the frequency of use of the umbrella cover 3. It is easy to understand that when the driving member 22 rotates one circle, under the action of the acceleration structure, the winding member 23 can rotate multiple circles, thereby reducing the number of circles rotated by the user, speeding up the storage speed of the umbrella cover 3, shortening the user's operation time, and improving the user experience.

[0046] In a preferred embodiment, the acceleration structure includes a ring gear 24 installed or formed on the winding member 23, at least one star gear 25 meshing with the ring gear 24, and a sun gear 26 arranged concentrically with the ring gear 24 and meshing with the star gear 25, the sun gear 26 is fixed to the base 21 via a main shaft 27, and the rotating shaft 28 of the star gear 25 is installed or formed on the driving member 22. Exemplarily, three star gears 25 are arranged in an array along the circumferential direction of the sun gear 26, and the diameter of each star gear 25 is smaller than the diameter of the sun gear 26, thereby improving the transmission efficiency and carrying capacity. The driving member 22 is equivalent to a planetary carrier, on which a rotating shaft 28 is provided corresponding to each star gear 25, and a stopper 281 is configured at the bottom of the rotating shaft 28, and the connection between the stopper 281 and the rotating shaft 28 can be a threaded connection or other structures, and the axial position of the star gear 25 is limited by the stopper 281. The sun gear 26 is fixed, that is, it is in a static state. When the driving member 22 (i.e., the planet carrier) rotates, each star gear 25 rotates and revolves with the driving member 22, thereby driving the ring gear 24 to rotate, so that the winding member 23 accelerates the rotation. Among them, the ring gear 24 and the winding member 23 can be integrally formed, or they can be assembled and fixed, for example, fixed by fasteners such as screws, without specific limitation. The ring gear 24, the star gear 25 and the sun gear 26 can be made of metal to ensure the meshing life. It should be mentioned that in this embodiment, the sun gear 26 is fixed, the driving member 22 (i.e., the planet carrier) is used as the input end, and the ring gear 24 is used as the output end. The transmission ratio is between 0.6 and 0.8. The structure of the planetary gear can ensure that the transmission process is smooth and reliable, and a stable speed increase can be achieved. Its calculation method and gear tooth number design are prior art and will not be repeated here.

[0047] In one embodiment, the main shaft 27 passes through the center of the driving member 22, the sun gear 26 and the winding member 23 in sequence, and is coaxially connected to the base 21, wherein the main shaft 27 includes a limiting portion 271, a positioning portion 272 and a connecting portion 273, wherein the limiting portion 271 is sleeved in the limiting hole 221 of the driving member 22, the positioning portion 272 is connected to the sun gear 26 and is used to limit the rotation of the sun gear 26, and the connecting portion 273 is used to be fixed to the base 21. Preferably, the main shaft 27 is in the shape of a stepped shaft, and the outer diameters of the limiting portion 271, the positioning portion 272 and the connecting portion 273 decrease in sequence, for example, the cross section of the main shaft 27 is T-shaped, the limiting portion 271 is located at the top of the main shaft 27, the positioning portion 272 is configured as a spline or a key, and the connecting portion 273 is configured as a thread. During assembly, the main shaft 27 is inserted along the limiting hole 221 of the driving member 22, and then the sun gear 26 is sleeved on the main shaft 27, and the star gears 25 are arranged in sequence, and then the winding member 23 is sleeved, and finally the base 21 and the main shaft 27 are screwed together. During disassembly, the base 21 can be screwed down, which is convenient for disassembly and assembly. In addition, the storage mechanism 2 of this embodiment has a simple structure and fewer parts, which can save production costs.

[0048] On the basis of the above-mentioned embodiment, in an optional embodiment of the utility model, the driving member 22 is in the shape of a cover, which is used to cover the base 21 and the winding assembly, so that the storage mechanism 2 has a neat appearance, improves the aesthetics of the storage mechanism 2, and is also convenient for the storage mechanism 2 to match the appearance of the umbrella body 1. In addition, a force-applying portion 222 is formed by a convex or concave arrangement on the outer circumference of the driving member 22, wherein the force-applying portion 222 can be a groove arranged in an array along the circumferential direction of the driving member 22, or can be an anti-skid fine line arranged on the outer circumference of the driving member 22, so as to increase the friction force of the outer circumference of the driving member 22, thereby facilitating the user to rotate the driving member 22, and is not limited to this and is not specifically limited.

[0049] In another preferred embodiment, a clamping portion 231 is provided at one end of the winding member 23 away from the gear ring 24, and the clamping portion 231 is used to engage with the limiting groove 211 on the base 21, so that the winding member 23 is limited in its axial direction. Exemplarily, the clamping portion 231 is configured as a buckle, and the limiting groove 211 is annularly recessed along the outer circumference of the base 21. When installing, the winding member 23 is inserted into the base 21 in the axial direction, and is clamped and limited with the limiting groove 211 on the base 21, so that the winding member 23 can be rotatably arranged on the base 21. The end of the umbrella cover 3 away from the opening is fixed to the winding member 23. When the winding member 23 rotates, it drives the umbrella body 1 to move in a spiral motion along the axial direction, so as to realize the storage of the umbrella cover 3.

[0050] Preferably, the base 21 has a mounting portion 212 at one end for connecting with the main shaft 27, and a mounting portion 213 at the other end for connecting with the umbrella body 1, and a boss 214 is extended outward from the middle of the base 21, wherein the mounting portion 212 is set as a threaded hole, and the mounting portion 213 is provided with an external thread for connecting with the umbrella body 1, and the periphery of the boss 214 cooperates with the bottom of the driving member 22 to form a clamping channel 2B entering the accommodating space 2A. The size of the clamping channel 2B is set to be greater than twice the thickness of the umbrella cover 3 and less than six times the thickness of the umbrella cover 3, so as to ensure that the umbrella cover 3 can be arranged when passing through the clamping channel 2B, but it is not limited to this and is not specifically limited. Preferably, the driving member 22 is provided with an arc surface 223 for abutting against the umbrella cover 3, and the arc surface 223 is frictionally matched with the outer surface of the umbrella cover 3. The driving member 22 can be a plastic part. Through injection molding, the arc surface 223 can be a chamfered corner set at the abutment position. By making patterns on the injection mold to increase the roughness of the arc surface 223, the friction between the arc surface 223 and the outer surface of the umbrella cover 3 is increased. At the same time, the setting of the arc surface 223 can avoid sharp angles from puncturing or scratching the umbrella cover 3, causing damage to the umbrella cover 3.

[0051] On the basis of the above-mentioned embodiments, in an optional embodiment of the utility model, the umbrella cover 3 is provided with a resistance member 31 for acting on the outer periphery of the umbrella body 1 near the opening, and the resistance member 31 is configured as a friction surface or an elastic ring. By providing the resistance member 31, the umbrella cover 3 can be kept in the inserted state after being inserted into the umbrella cover 3, and is not easy to fold. At the same time, the resistance member 31 can increase the resistance when the umbrella cover 3 is displaced, so that one end of the umbrella cover 3 is spirally stored, and the other end forms a resistance, ensuring that the middle part of the umbrella cover 3 is not easy to loosen during the storage process, and realizing the smooth spiral rise or descent process. In one preferred embodiment, the resistance member 31 is configured as a friction surface, which is formed or fixed on the inner surface of the umbrella cover 3 and frictionally matched with the outer periphery of the umbrella body 1; the friction surface here refers to a material surface with a friction coefficient greater than the friction coefficient of the umbrella cloth, such as a silicone strip, a velvet strip, etc. During the spiral movement of the umbrella cover 3, the friction surface of the inner surface and the umbrella cloth frictionally cooperate to form a small resistance. In another embodiment, the resistance member 31 is configured as an elastic ring, which is installed or formed on the umbrella cover 3 and is close to one end of the opening of the umbrella cover 3; wherein the elastic ring is sleeved and acts on the outer periphery of the umbrella body 1; specifically, an elastic ring is sewn on the umbrella cover 3 and close to one end of the opening, which is generally made of rubber rope or elastic band, and its diameter is slightly smaller than the outer diameter of the outer periphery of the umbrella body 1, so that the umbrella cover 3 can contact the outer periphery of the umbrella body 1 when making axial movement, and play a certain resistance; in other embodiments, the resistance member 31 is configured as a constriction formed on the umbrella cover 3; that is, a constriction is formed on one end of the umbrella opening, and the design of this constriction is limited to the umbrella cover 3 being made of elastic material, such as elastic cloth, very thin rubber cover, etc., and the constriction is set so as to cooperate with the umbrella body 1 when rolling up. It should be noted that the outer periphery of the umbrella body 1 mentioned above refers to the maximum diameter of the umbrella ribs and umbrella cloth in the folded state.

[0052] Combination Fig.12 and Fig.13 The utility model further provides a folding umbrella, comprising an umbrella body 1, an umbrella cover 3 and an umbrella cover accelerating storage mechanism 2 as described in any of the above embodiments, wherein the storage mechanism 2 is mounted on the top of the umbrella body 1 and / or the umbrella handle end 11 through a base 21, and the winding assembly is fixed to one end of the umbrella cover 3, and the winding member 23 is driven to accelerate the rotation by a rotating driving member 22 through a linkage acceleration structure, so that the umbrella cover 3 is quickly rolled up in the storage mechanism 2 along the axial direction of the umbrella body 1.
