Description

Technical Field

[0001] The present invention relates to the technical field of umbrellas, and in particular to an electric umbrella. Background Art

[0002] Umbrellas are essential household items in people's daily lives. Traditional umbrellas can be divided into fully manual umbrellas and semi-automatic umbrellas. Fully manual umbrellas require manual operation to open and close, while semi-automatic umbrellas can be opened automatically, but also require manual operation when closing.

[0003] The opening and closing operations of a fully manual umbrella and the closing operations of a semi-automatic umbrella both require a large operating force to be applied to the umbrella, which undoubtedly increases the difficulty of use for the elderly or children. For normal adults, it is also difficult to open and close a fully manual umbrella or close a semi-automatic umbrella with one hand when holding other objects. It can be seen that traditional umbrellas are extremely inconvenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide an electric umbrella, aiming to solve the technical problem that existing umbrellas are inconvenient to use.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an electric umbrella, comprising a driving assembly, a first traction assembly, a second traction assembly, an umbrella rod assembly, an umbrella rib assembly, an upper nest fixedly provided at one end of the umbrella rod assembly, and a lower nest movably mounted on the umbrella rod assembly; the umbrella rib assembly comprises a first rib and a second rib rotatably connected to each other, and an elastic member connected between the first rib and the second rib, one end of the first rib is rotatably connected to the lower nest, and one end of the second rib is rotatably connected to the upper nest; the umbrella rod assembly comprises a first tube rod, a second tube rod and a third tube rod which are sequentially sleeved, the driving assembly is provided on the first tube rod, the driving assembly drives the second tube rod and the third tube rod to perform linear reciprocating motion along the axial direction of the umbrella rod assembly through the first traction assembly, and the umbrella rod assembly drives the lower nest to move toward the upper nest through the second traction assembly.

[0006] The electric umbrella provided by the present invention has at least the following beneficial effects: when opening the electric umbrella, the drive assembly operates to pull the second and third tubes outwardly along the axial direction of the umbrella rod assembly through the first pulling assembly. At the same time, during the extension process, the second and third tubes pull the lower nest toward the upper nest through the second pulling assembly, so that the first rib props up the second rib and the elastic member enters a stretched state. At this time, the second pulling assembly overcomes the elastic force of the elastic member and pulls the lower nest. When the second and third tubes are fully extended, the rib assembly is also fully propped up, completing the opening operation of the electric umbrella. When closing the electric umbrella, the drive assembly operates in the reverse direction, pulling the second and third tubes inwardly along the axial direction of the umbrella rod assembly through the first pulling assembly. When the second and third tubes retract, the lower nest loses the pulling force of the second pulling assembly, and the elastic force of the elastic member folds the first and second ribs and pushes the lower nest away from the upper nest. When the second and third tubes are fully retracted, the closing operation of the electric umbrella is completed. The opening and closing operations of the electric umbrella are all performed automatically without manual intervention, and the operation is labor-saving and convenient to use.

[0029] Example 1

[0030] Please combine Figures 1 to 5 As shown, an electric umbrella includes a drive assembly 10, a first traction assembly 20, a second traction assembly 30, an umbrella shaft assembly 40, an umbrella rib assembly 50, an upper nest 70 fixed to one end of the umbrella shaft assembly 40, and a lower nest 60 movably mounted on the umbrella shaft assembly 40; the umbrella rib assembly 50 includes a first umbrella rib 51 and a second umbrella rib 52 rotatably connected to each other, and an elastic member 53 connected between the first umbrella rib 51 and the second umbrella rib 52, one end of the first umbrella rib 51 is rotatably connected to the lower nest 60, and one end of the second umbrella rib 52 is rotatably connected to the upper nest 70; the umbrella shaft assembly 40 includes a first tube rod 41, a second tube rod 42 and a third tube rod 43 that are sequentially sleeved, and the drive assembly 10 is mounted on the first tube rod 41. The drive assembly 10 drives the second tube rod 42 and the third tube rod 43 to perform linear reciprocating motion along the axial direction of the umbrella shaft assembly 40 through the first traction assembly 20, and the umbrella shaft assembly 40 drives the lower nest 60 to move toward the upper nest 70 through the second traction assembly 30.

[0031] When the electric umbrella is opened, the driving assembly 10 is operated, and the second tube rod 42 and the third tube rod 43 are pulled outward along the axial direction of the umbrella rod assembly 40 through the first pulling assembly 20. At the same time, the second tube rod 42 and the third tube rod 43 are pulled by the second pulling assembly 30 to move the lower nest 60 toward the upper nest 70 during the extension process, so that the first umbrella rib 51 props up the second umbrella rib 52, and at the same time, the elastic member 53 enters a stretched state. At this time, the second pulling assembly 30 overcomes the elastic force of the elastic member 53 and pulls the lower nest 60. When the second tube rod 42 and the third tube rod 43 are fully extended, the umbrella rib assembly 50 is also The electric umbrella is then fully extended, completing the opening operation. To close the electric umbrella, the drive assembly 10 operates in reverse, pulling the second and third rods 42, 43 inwardly along the axial direction of the rod assembly 40 via the first traction assembly 20. As the second and third rods 42, 43 retract, the lower nest 60 loses the pulling force of the second traction assembly 30, and the elastic force of the elastic member 53 folds the first and second ribs 51, 52, and pushes the lower nest 60 away from the upper nest 70. When the second and third rods 42, 43 are fully retracted, the electric umbrella is closed. The opening and closing operations of the electric umbrella are both automatic, requiring no human intervention, and are labor-saving and convenient to use.

[0032] The elastic member 53 may be a tension spring. Of course, there are many types of elastic members 53, such as a gas pressure rod, etc., which are not specifically limited here.

[0033] Specifically, please combine Figure 1 As shown, the umbrella rib assembly 50 also includes a first rib 56, a second rib 57, and a third rib 54 and a fourth rib 55 that are rotatably connected to each other. One end of the third rib 54 away from the fourth rib 55 is rotatably connected to the second rib 52, one end of the first rib 56 is rotatably connected to the first rib 51 and the other end is rotatably connected to the third rib 54, and one end of the second rib 57 is rotatably connected to the second rib 52 and the other end is rotatably connected to the third rib 54.

[0034] In one embodiment, please continue to refer to Figures 1 to 5 The drive assembly 10 includes a driver 11 and a first reel 12 connected to the power output end of the driver 11. The first traction assembly 20 includes a second reel 21 rotatably mounted on a first rod 41, a third reel 22 rotatably mounted on one end of a second rod 42, a fourth reel 23 rotatably mounted on the other end of the second rod 42, and a first pulley 24 sequentially wound around the first reel 12, the second reel 21, the third reel 22, and the fourth reel 23. The two ends of the first pulley 24 are respectively fixedly connected to opposite ends of the third rod 43. The driver 11 can be a motor.

[0035] To facilitate understanding of the above embodiments, the following defines the part of the first pulley 24 located between the first wire wheel 12 and the second wire wheel 21 as the first movable segment, the part located between the second wire wheel 21 and the third wire wheel 22 as the second movable segment, the part located between the third wire wheel 22 and the fourth wire wheel 23 as the third movable segment, the part located between the fourth wire wheel 23 and the third tube rod 43 as the fourth movable segment, and the part located between the first wire wheel 12 and the third tube rod 43 as the fifth movable segment, so as to further illustrate the above embodiments.

[0036] Please combine Figure 1 、 Figure 4 and Figure 5 As shown, when the electric umbrella is opened, the driver 11 drives the first pulley 12 to rotate. At this time, the length of the first movable segment remains unchanged and is transported toward the first pulley 12, the length of the second movable segment is shortened and is transported toward the second pulley 21, the length of the third movable segment remains unchanged and is transported toward the third pulley 22, the length of the fourth movable segment is shortened and is transported toward the fourth pulley 23, and the length of the fifth movable segment increases and is transported away from the first pulley 12. In this way, due to the shortening of the length of the second movable segment, the second tube rod 42 is pulled outward, and the As the length of the fourth movable section is shortened, the third tube rod 43 is pulled outward, and the fifth movable section is extended as the second tube rod 42 and the third tube rod 43 are extended; in addition, during the extension of the second tube rod 42 and the third tube rod 43, the lower nest 60 is pulled toward the upper nest 70 by the second traction assembly 30, so that the first umbrella rib 51 props up the second umbrella rib 52. At this time, the elastic member 53 is stretched and deformed to store potential energy for closing the electric umbrella; when closing the above-mentioned electric umbrella, the driver 11 drives the first pulley 12 to rotate in the opposite direction. At this time, the length of the first movable section remains unchanged and The first movable segment is transported in the direction away from the first pulley 12, the length of the second movable segment increases and is transported in the direction away from the second pulley 21, the length of the third movable segment remains unchanged and is transported in the direction away from the third pulley 22, the length of the fourth movable segment increases and is transported in the direction away from the fourth pulley 23, the length of the fifth movable segment is shortened and is transported in the direction close to the first pulley 12, so that the fourth movable segment loses the extending pulling force acting on the third tube rod 43, the second movable segment loses the extending pulling force acting on the second tube rod 42, and because the length of the fifth movable segment is shortened, the third tube rod 43 is pulled inward Retraction: When the third tube rod 43 retracts to the position pressing against the second tube rod 42, the fifth movable section pulls the second tube rod 42 and the third tube rod 43 to retract together until the second tube rod 42 retracts to the position pressing against the first tube rod 41, that is, the umbrella rod assembly 40 is fully retracted; in addition, during the retraction process of the third tube rod 43, the second traction assembly 30 loses the pulling force acting on the lower nest 60. At this time, the elastic member 53 contracts to pull the first rib 51 and the second rib 52 to fold, thereby pushing the lower nest 60 to move away from the upper nest 70 until the umbrella rib assembly 50 is fully folded.

[0037] Specifically, please combine Figure 1 、 Figure 4 and Figure 5 As shown, the drive assembly further includes a transmission assembly, wherein the axis of the driver 11 is arranged vertically, and the axis of the first spool 12 is arranged horizontally. One end of the transmission assembly is fixedly connected to the output end of the driver 11, and the other end is fixedly connected to the first spool 12. By configuring the transmission assembly to change the transmission direction of the driver 11, the axis of the first spool 12 is perpendicular to the output axis of the driver 11 and the axis of the umbrella shaft assembly 40. When the driver 11 drives the first spool 12 to rotate, the first spool 12 releases or retracts the first pull wire 24 along the axial direction of the umbrella shaft assembly 40.

[0038] Among them, there are various structures of the transmission assembly, such as the transmission assembly includes a first bevel gear 13 and a second bevel gear 14 that are meshed with each other, the first bevel gear 13 is fixedly connected to the output end of the driver 11, and the second bevel gear 14 is fixedly connected to the first pulley; for example, the transmission assembly includes a worm and a worm wheel that are meshed with each other, the worm is fixedly connected to the output end of the driver 11, and the worm wheel is fixedly connected to the first pulley; no specific limitation is given here.

[0039] In one embodiment, please combine Figure 1 、 Figure 4 and Figure 5 As shown, the second traction assembly 30 includes a fifth pulley 31 rotatably mounted on the third pipe rod 43 and a second pull wire 32 wound around the fifth pulley 31, one end of the second pull wire 32 is fixedly connected to the lower nest 60 and the other end is fixedly connected to the second pipe rod 42.

[0040] The operation process of the first traction assembly 20 and the second traction assembly 30 will be further described below.

[0041] Please combine Figure 1 、 Figure 4 and Figure 5 As shown, when the electric umbrella is opened (at this time Figure 5In the state shown), the driver 11 drives the first spool 12 to rotate. At this time, the length of the first movable segment remains unchanged and is transported toward the first spool 12. The length of the second movable segment is shortened and is transported toward the second spool 21. The length of the third movable segment remains unchanged and is transported toward the third spool 22. The length of the fourth movable segment is shortened and is transported toward the fourth spool 23. The length of the fifth movable segment increases and is transported away from the first spool 12. In this way, due to the shortening of the length of the second movable segment, the second pipe rod 42 is pulled outward, and due to the shortening of the length of the fourth movable segment, the third pipe rod 43 is pulled outward, and the fifth movable segment is extended as the second pipe rod 42 and the third pipe rod 43 are extended. In addition, when the third tube rod 43 is extended outward, it will drive the second pull line 32 to pull the lower nest 60 toward the upper nest 70, so that the first umbrella rib 51 will prop up the second umbrella rib 52 and stretch the elastic member 53. The elastic force generated by the elastic member 53 after stretching is transmitted to the third tube rod 43 through the lower nest 60 and the second traction assembly 30 in turn. That is, when the fourth movable section pulls the third tube rod 43 outward, it also needs to overcome the elastic force of the elastic member 53, and the second tube rod 42 is not affected by any other external force except its own gravity and friction. Therefore, when the first pulley 12 rotates, the first pull line 24 first pulls the second tube rod 42 outward. When the second tube rod 42 is fully extended (at this time), Figure 4 As shown in the state shown), the first pull line 24 continues to pull the third tube rod 43 outward, and during the extension of the third tube rod 43, the fifth pulley 31 moves with the third tube rod 43 in the direction away from the first pulley 12, so that the second pull line 32 pulls the lower nest 60 to move closer to the upper nest 70, so that the first umbrella rib 51 props up the second umbrella rib 52 and stretches the elastic member 53 to store potential energy for closing the electric umbrella (at this time Figure 1 When the electric umbrella is closed (at this time Figure 1The first movable segment is in the state shown in FIG1 , and the driver 11 drives the first pulley 12 to rotate in the opposite direction. At this time, the length of the first movable segment remains unchanged and is transported in the direction away from the first pulley 12. The length of the second movable segment increases and is transported in the direction away from the second pulley 21. The length of the third movable segment remains unchanged and is transported in the direction away from the third pulley 22. The length of the fourth movable segment increases and is transported in the direction away from the fourth pulley 23. The length of the fifth movable segment is shortened and is transported in the direction close to the first pulley 12. In this way, the fourth movable segment loses the extension pulling force acting on the third pipe rod 43. The force is applied to the second movable section, and the second movable section loses the extending pulling force acting on the second tube rod 42. As the length of the fifth movable section is shortened, the third tube rod 43 is pulled inwardly, and the fifth wire wheel 31 follows the third tube rod 43 to move toward the first wire wheel 12, so that the second pull line 32 also loses the pulling force acting on the lower nest 60. At this time, the elastic member 53 recovers to fold the first rib 51 and the second rib 52 to push the lower nest 60 toward the first wire wheel 12. When the third tube rod 43 is retracted to the position of pressing against the second tube rod 42 (at this time), the fifth wire wheel 31 is in the position of pressing against the second tube rod 42. Figure 4 The fifth movable section pulls the second tube rod 42 and the third tube rod 43 back together until the second tube rod 42 is retracted to the position where it presses against the first tube rod 41, that is, the umbrella rod assembly 40 is fully retracted and the umbrella rib assembly 50 is fully folded (at this time, the umbrella rod assembly 40 is fully retracted and the umbrella rib assembly 50 is fully folded). Figure 5 status shown).

[0042] It can be seen from the above content that no matter whether the electric umbrella is in the opening process or the closing process, the first pull wire 24 of the first traction component 20 and the second pull wire 32 of the second traction component 30 are always kept in a taut state. When the driver 11 is running, the first traction component 20 and the second traction component 30 respond successively, so that the overall operation of the electric umbrella responds in time, effectively improving the user experience.

[0043] In one embodiment, please combine Figure 1 、 Figure 4 and Figure 5As shown, the electric umbrella further includes a controller 80 and a button assembly 90 electrically connected to the controller 80, and the drive assembly 10 is electrically connected to the controller 80. The user sends instructions to the controller 80 by operating the button assembly 90, so that the controller 80 controls the drive assembly 10 to run forward or reverse. It should be noted that when the above-mentioned electric umbrella is moved from a closed state to a fully open state, the drive assembly 10 is stalled, and the controller 80 will detect a large current, thereby controlling the drive assembly 10 to be powered off; conversely, when the above-mentioned electric umbrella is moved from an open state to a fully closed state, the drive assembly 10 is also stalled, and the controller 80 will also detect a large current, thereby controlling the drive assembly 10 to be powered off. Of course, there are many ways for the controller 80 to control the drive assembly 10 to be powered off, such as controlling the drive assembly 10 to be powered off by detecting the number of rotations of the drive assembly 10; or controlling the drive assembly 10 to be powered off by detecting the operating time of the drive assembly 10; these are not limited here.

[0044] Specifically, please combine Figure 1 、 Figure 4 and Figure 5 As shown, the button assembly 90 includes a first button 91 and a second button 92. The first button 91 is used to control the forward operation of the drive assembly 10, and the second button 92 is used to control the reverse operation of the drive assembly 10. When the user presses the first button 91, the controller 80 controls the drive assembly 10 to operate in the forward direction to open (close) the electric umbrella. When the user presses the second button 92, the controller 80 controls the drive assembly 10 to operate in the reverse direction to close (open) the electric umbrella. Operation is simple and convenient.

[0045] There are many types of the first button 91 and the second button 92, such as mechanical buttons, touch buttons, etc., which are not specifically limited here.

[0046] Furthermore, please combine Figure 1 、 Figure 4 and Figure 5 As shown, a handle 411 is provided at one end of the first tube 41 away from the upper nest 70. The interior of the handle 411 forms a receiving cavity 4111 for accommodating the controller 80, the button assembly 90, and the drive assembly 10. Accommodating the controller 80, the button assembly 90, and the drive assembly 10 within the receiving cavity 4111 of the handle 411 prevents these components from being exposed, thus improving the appearance of the electric umbrella and enhancing its visual appeal.

[0047] In one embodiment, a limiting structure is provided between the first tube rod 41 and the second tube rod 42, and between the second tube rod 42 and the third tube rod 43. The limiting structure prevents the second tube rod 42 from being separated from the first tube rod 41 after being fully extended, and prevents the third tube rod 43 from being separated from the second tube rod 42 after being fully extended, thereby improving the reliability of the electric umbrella.

[0048] Among them, there are many types of limiting structures, such as providing a first bayonet at an end of the first tube rod 41 away from the driving assembly 10, providing a first clamping point for cooperating with the first bayonet at an end of the second tube rod 42 close to the driving assembly 10 and a second bayonet at the other end, and providing a second clamping point for cooperating with the second bayonet at an end of the third tube rod 43 close to the driving assembly 10; for another example, providing a first clamping ring at an end of the first tube rod 41 away from the driving assembly 10, providing a second clamping ring for abutting with the first clamping ring at an end of the second tube rod 42 close to the driving assembly 10 and a third clamping ring at the other end, and providing a fourth clamping ring for abutting with the third clamping ring at an end of the third tube rod 43 close to the driving assembly 10; as long as the limiting structure can achieve mutual buckling between the first tube rod 41 and the second tube rod 42 and the mutual buckling between the second tube rod 42 and the third tube rod 43, it can be applied to the above-mentioned electric umbrella, and examples are not given one by one here.

[0049] In one embodiment, please combine Figure 1 、 Figure 4 and Figure 5 As shown, the electric umbrella further includes a battery 111, and the battery 111 is electrically connected to the driving assembly 10. By providing the battery 111 to continuously power the electric umbrella, it is convenient for the user to carry the electric umbrella for use outside.

[0050] Furthermore, the electric umbrella also includes a power indicator (not shown), which is electrically connected to the battery 111. When the battery 111 is low on power, the indicator promptly reminds the user to charge or replace the battery 111, further improving the convenience of using the electric umbrella.

[0051] Example 2

[0052] Please combine Figure 1 、 Figure 4 and Figure 5 As shown, the first pull line 24 includes a first line segment 241 and a second line segment 242. One end of the first line segment 241 is fixedly connected to the first pulley 12 and the other end is fixedly connected to the end of the third pipe rod 43 away from the drive assembly 10. The second line segment 242 is sequentially wound around the second pulley 21, the third pulley 22 and the fourth pulley 23. One end of the second line segment 242 is fixedly connected to the first pulley 12 and the other end is fixedly connected to the end of the third pipe rod 43 close to the drive assembly 10. The operation process of the first traction assembly 20 of this embodiment is the same as the operation process of the first traction assembly 20 of Example 1, and will not be described in detail here.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
