In this embodiment, the umbrella rod assembly 12 further includes an umbrella rod driving assembly 600 and an umbrella rib driving assembly 700, the umbrella rod driving assembly 600 and the umbrella rib driving assembly 700 are used cooperatively, so that when the umbrella opening button 112 is pressed, the driving assembly 120 can open the electric umbrella 10 through the umbrella rod driving assembly 600 and the umbrella rib driving assembly 700, and when the umbrella folding button 114 is pressed, the driving assembly 120 can close the electric umbrella 10 through the umbrella rod driving assembly 600 and the umbrella rib driving assembly 700.

In this embodiment, the umbrella shaft assembly 600 is used in the shaft 200 of the electric umbrella 10. When the umbrella rod transmission assembly 600 applies force to the middle rod 200, a plurality of sleeves of the middle rod 200 can be pulled apart to form a long rod connected end to end, so that the umbrella rod of the electric umbrella 10 is extended, namely, the step of opening the umbrella rod of the electric umbrella 10 to extend is completed; when the force applied to the middle rod 200 by the umbrella shaft driving assembly 600 is removed, the plurality of sleeves of the middle rod 200 can be sleeved from inside to outside under the force of the tension spring 530 (described in detail later), thereby completing the step of shortening the umbrella shaft of the electric umbrella 10.

In this embodiment, as shown in fig. 6-11, the umbrella shaft driving assembly 600 includes a first shaft structure 610, a second shaft structure 620 and a spring 630.

The first rod structure 610 is a hollow structure open at both ends. The first rod structure 610 includes a first rod 612 and a rotation-blocking portion 614, and the rotation-blocking portion 614 is disposed at one end of the first rod 612. The outer diameter of the rotation-blocking portion 614 is larger than the outer diameter of the first rod 612.

The second rod structure 620 includes a second rod 622 and a pressure spring 624, and the pressure spring 624 is disposed at one end of the second rod 622. The outer diameter of the compressed spring portion 624 is larger than that of the second rod 622, and the outer diameter of the compressed spring portion 624 is larger than that of the rotation blocking portion 614. The second rod 622 is inserted into the first rod structure 610, and the compressed spring 624 is located outside of an end of the rotation-blocking portion 614 away from the first rod 612. The end surface of the pressure spring portion 624 close to the second rod 622 is a pressure spring surface 6242, and the pressure spring portion 624 is provided with a spring guide passage 6244.

The spring 630 is disposed over the first rod structure 610, and at least a portion of the coil 632 of the spring 630 is disposed in the spring guide passage 6244.

When the second rod structure 620 and the first rod structure 610 rotate relatively, the spring 630 compressed on the side of the pressure spring face 6242 close to the second rod body 622 can be released, so that the spring 630 extends out from one end of the pressure spring portion 624 far from the rotation-blocking portion 614, and applies force to the middle rod 200, so that the plurality of sleeves of the middle rod 200 are pulled apart to form a long rod connected end to end.

When the second rod structure 620 and the first rod structure 610 rotate relatively, the spring 630 extending out of the compressed spring portion 624 can be compressed on the side of the compressed spring surface 6242 close to the second rod body 622 to cancel the force applied by the spring 630 to the middle rod 200.

That is, when the first rod structure 610 is fixed and the second rod structure 620 rotates in the first direction, the spring 630 compressed on the side of the compressed spring surface 6242 close to the second rod 622 can be released, and when the second rod structure 620 rotates in the second direction, the spring 630 extending out of the compressed spring portion 624 can be compressed on the side of the compressed spring surface 6242 close to the second rod 622. Wherein the first direction is opposite to the second direction, for example, when the first direction is clockwise, the second direction is counterclockwise; when the first direction is counterclockwise, the second direction is clockwise.

When the second rod structure 620 is fixed and the first rod structure 610 rotates in the first direction, the spring 630 compressed on the side of the compressed spring surface 6242 close to the second rod 622 can be released, and when the first rod structure 610 rotates in the second direction, the spring 630 extending out of the compressed spring portion 624 can be compressed on the side of the compressed spring surface 6242 close to the second rod 622.

When the first rod structure 610 is fixed and the second rod structure 620 rotates in the first direction, the spring 630 compressed on the side of the compressed spring surface 6242 adjacent to the second rod 622 can be released; when the second rod structure 620 is fixed and the first rod structure 610 rotates in the first direction, the spring 630 extending out of the compressed spring portion 624 can be compressed on the side of the compressed spring surface 6242 close to the second rod 622.

In the umbrella shaft transmission assembly 600, the second shaft structure 620 rotates relative to the first shaft structure 610, and the spring 630 compressed on the side of the compressed spring face 6242 close to the second shaft body 622 is released, so that the spring 630 extends from the end of the compressed spring portion 624 far from the rotation blocking portion 614, and applies force to the middle rod 200, so that the plurality of sleeves of the middle rod 200 are pulled apart to form a long shaft connected end to end. In this way, the shaft of the electric umbrella 10 is extended, that is, the step of extending the shaft of the electric umbrella 10 is completed. The second rod structure 620 rotates relative to the first rod structure 610, and the spring 630 extending out of the compressed spring portion 624 can be compressed on the side of the compressed spring surface 6242 close to the second rod body 622, thereby removing the force applied to the middle rod 200 by the spring 630. Thus, under the action of other elements, the plurality of sleeves of the middle rod 200 can be sleeved from inside to outside, so as to complete the step of shortening the umbrella rod of the electric umbrella 10.

That is, the above-described umbrella shaft driving assembly 600 can be extended and can facilitate the shortening of the umbrella shaft of the electric umbrella 10, and the structure of the umbrella shaft driving assembly is made simpler by using the relative rotation of the first shaft structure 610 and the second shaft structure 620 in cooperation with the spring 630. And through the cooperation of the rotation blocking part 614 and the pressure spring part 624, the rotation movement of the spring 630 in the releasing and compressing process can be reduced, and the linear movement of the spring 630 is ensured, so that the spring 630 is ensured to be more easily released and compressed, and the energy consumption of the relative rotation of the second rod structure 620 and the first rod structure 610 is reduced.

Taking the elongated spring 630 in the vertical direction as an example, when the spring 630 is in a natural state, the coils 632 of the spring 630 are inclined with respect to the vertical direction, have a certain gradient, and are substantially in a sloping plate shape; when the spring 630 is in a compressed state, the coil 632 is substantially perpendicular to the vertical direction and has a substantially flat plate shape. The inner diameter of the coil 632 of the spring 630 becomes smaller after the spring 630 is shifted from the compressed state to the natural state, and the inner diameter of the coil 632 becomes larger after the spring 630 is shifted from the natural state to the compressed state.

In this embodiment, the inner diameter of the guide spring passage 6244 is smaller than the inner diameter of the rotation blocking portion 614. The larger outer diameter rotation stop 614 is disposed between the first rod 612 and the spring guide passage 6244, so that the spring 630 can be released and compressed more easily.

In this embodiment, the outer diameter of the rotation resistance portion 614 is substantially equal to the inner diameter of the spring 630 in a compressed state. Thus, when the second rod structure 620 rotates relative to the first rod structure 610, the rotation-blocking portion 614 can interfere with the spring 630, so as to block the rotation of the spring 630, and further, the spring 630 can be released and compressed more easily.

In other embodiments, the outer diameter of the rotation-blocking portion 614 may be larger than the inner diameter of the spring 630 in the compressed state, so that the rotation-blocking portion 614 interferes with the spring 630 in the compressed state when the electric umbrella 10 is in the collapsed state.

In the present embodiment, the first rod 612 and the rotation-blocking portion 614 are both cylindrical. The first rod 612 and the rotation-blocking portion 614 are integrally formed. In other embodiments, an open end of the first rod structure 610 is flared outward, thereby forming a rotation stop 614, and the portion that is not flared is the first rod body 612. In this way, the outer diameter of the rotation blocking portion 614 may gradually increase in the direction from the first rod 612 to the rotation blocking portion 614 (at this time, the outer diameter of the region where the outer diameter of the rotation blocking portion 614 is the smallest is larger than the outer diameter of the first rod 612, and the outer diameter of the region where the outer diameter of the rotation blocking portion 614 is the largest is larger than the inner diameter of the guide spring passage 6244). In this manner, the spring 630 may be more easily released and compressed.

In the present embodiment, the second rod 622 and the pressure spring 624 are both cylindrical. The second rod 622 and the pressure spring 624 are integrally formed.

In this embodiment, the spring 630 located on the side of the compressed spring surface 6242 away from the second rod 622 is in a natural state, that is, the spring 630 located in the guide spring passage 6244 is in a natural state.

In this embodiment, the shape of the guide spring passage 6244 is adapted to the shape of the coils 632 of the spring 630 in the natural state. In this manner, the spring 630 in the guide spring passage 6244 can be in a natural state, and the spring 630 can be released and compressed more easily.

Specifically, the pressure spring portion 624 extends spirally in the extending direction of the first rod 612. In some embodiments, as shown in fig. 9-13, the pressure spring portion 624 includes at least one pressing ring 624a, and each pressing ring 624a is located between two adjacent spring coils 632. In some embodiments, as shown in fig. 14 and fig. 15, the pressure spring portion 624 is a portion of a pressing ring 624a, that is, the outer wall of the pressure spring portion 624 has a notch penetrating through both ends of the pressure spring portion 624 in the extending direction of the second rod 622. The pressure spring portion 624 includes at least one pressing ring 624a, which can effectively prevent the spring 630 (the spring 630 located on the side of the pressure spring face 6242 away from the second rod 622) from tilting. In other embodiments, the compressed spring portion 624 may be a roller sandwiched between two coils 632.

In the present embodiment, as shown in fig. 9 to 13, the pressure spring surface 6242 is provided with rollers 640. In the releasing process and the process of compressing the spring 630, the sliding friction between the spring 630 and the pressure spring surface 6242 is converted into the rolling friction between the spring 630 and the roller 640, so that the friction force of the spring 630 in the releasing process and the compressing process can be effectively reduced. In some embodiments, the plurality of rollers 640 are provided, and the plurality of rollers 640 are spaced apart from each other on the compression spring surface 6242.

The spring 630 compressed on the side of the compressed spring surface 6242 close to the second lever 622 exerts a large force on the compressed spring surface 6242, resulting in a large sliding friction between the spring 630 and the compressed spring surface 6242. After the roller 640 is arranged, the friction force of the spring 630 in the releasing process and the compressing process can be effectively reduced.

In some embodiments, the pressure spring face 6242 is recessed to form a mounting groove 6241, and the mounting groove 6241 penetrates the outer circumferential surface of the pressure spring portion 624 and forms a notch on the outer circumferential surface. The mounting groove 6241 and the notch are provided with a rotating shaft on the opposite groove wall, and the roller 640 is mounted on the rotating shaft.

In some embodiments, as shown in fig. 9-11, the mounting groove 6241 is cylindrical and, correspondingly, the roller 640 is also cylindrical. In some embodiments, as shown in fig. 12 and 13, the mounting groove 6241 is T-shaped, the roller 640 includes a position-limiting seat 642 and a roller body 644, the position-limiting seat 642 is disposed in the mounting groove 6241, and the roller body 644 is disposed on the position-limiting seat 642 through a rotation shaft.

In the present embodiment, as shown in fig. 1 to 8, the second rod structure 620 rotates relative to the first rod structure 610, and the spring 630 compressed on the side of the compressed spring surface 6242 close to the second rod 622 is released, so that the spring 630 protrudes from one end of the compressed spring portion 624 far from the rotation-blocking portion 614 and applies a force to the upper nest 300. And the upper nest 300 is fixed on the outer pipe 204 of the middle rod 200, thereby indirectly applying force to the middle rod 200, and leading a plurality of sleeves of the middle rod 200 to be pulled apart to form a long rod connected end to end.

Specifically, in the present embodiment, when the electric umbrella 10 is in the collapsed state, part of the spring 630 is located between the compressed spring portion 624 and the upper nest 300. More specifically, in the present embodiment, when the electric umbrella 10 is in the collapsed state, the springs 630 extending from the compression spring portions 624 are substantially in contact with the upper nest 300, i.e., the space between the springs 630 extending from the compression spring portions 624 and the upper nest 300 is very small. In this manner, the spring 630 exerts a force on the upper nest 300.

In this embodiment, the first rod structure 610 further includes a limiting portion 616. The limiting portion 616 is disposed on an end of the first rod 612 away from the rotation-blocking portion 614. In this way, the spring 630 can be compressed between the stopper portion 616 and the compressed spring portion 624. In other embodiments, the position-limiting portion 616 of the first rod structure 610 may be omitted, and a position-limiting portion may be formed on the inner tube 202 or the like, so that the spring 630 located on the side of the compressed spring surface 6242 close to the second rod body 622 can be compressed.

In this embodiment, the outer diameter of the spring 630 in the compressed state is substantially the same as the inner diameter of the inner tube 202 (slightly smaller than the inner diameter of the inner tube 202). This facilitates the release and compression of the spring 630 within the inner tube 202, while also allowing the spring 630 to have a larger outer diameter. The spring 630 having a larger outer diameter is advantageous in that it can obtain a greater strength, thereby better applying a force outward and stably supporting the upper nest 300.

In this embodiment, the second rod structure 620 is a hollow structure with both ends open. In this manner, routing of the drawstring 730 is greatly facilitated.

In this embodiment, the electric umbrella 10 further comprises a rib drive assembly 700, and the rib drive assembly 700 cooperates with the umbrella shaft drive assembly 600. When the umbrella stick transmission assembly 600 completes the step of opening the umbrella stick of the electric umbrella 10 to extend, the umbrella stick transmission assembly 700 opens the umbrella frame 500 of the electric umbrella 10; after the force applied to the central rod 200 by the umbrella rod transmission assembly 600 is removed, the umbrella framework 500 of the electric umbrella 10 is folded by the umbrella rib transmission assembly 700 under the action of the tension spring 530, and the plurality of sleeves of the central rod 200 are sleeved from inside to outside, so that the step of shortening the umbrella rod of the electric umbrella 10 is completed.

In this embodiment, rib drive assembly 700 includes at least one upper pulley 710, at least one lower pulley 720, and a pull cord 730. The upper pulley 710 is disposed on the upper nest 300. The lower pulley 720 is provided in the lower nest 400. The pulling rope 730 has one end fixed to the head 100 and the other end passing through the second rod structure 620, and then alternately goes around the upper pulley 710 and the lower pulley 720, and is fixed to the upper nest 300 or the lower nest 400.

When the electric umbrella 10 is used, after the umbrella opening button 112 is pressed, the driving assembly 120 rotates to drive the first rod structure 610 or the second rod structure 620 to rotate, the spring 630 is released and extends out from one end of the spring pressing portion 624 away from the rotation blocking portion 614, and after a force is applied to the upper nest 300, the upper nest 300 fixed on the outer tube 204 moves towards a direction away from the umbrella head 100, so that the sleeves of the middle rod 200 are pulled apart to form a long rod connected end to end, and the step of extending the umbrella rod of the electric umbrella 10 is completed. Meanwhile, as the upper nest 300 fixed on the outer tube 204 moves towards the direction far away from the umbrella head 100 relative to the umbrella head 100, at this time, the pull rope 730 pulls the lower nest 400 to slide towards the upper nest 300 on the outer tube 204, and drives the second ribs 520 to slide on the first ribs 510, so as to open the umbrella frame 500, and thus, the step of unfolding the umbrella frame 500 of the electric umbrella 10 is completed. At this time, the umbrella 10 is in the open state and the tension spring 530 is in the compressed state.

Then, when the umbrella folding button 114 is pressed, the driving unit 120 rotates reversely, and the first rod structure 610 or the second rod structure 620 rotates reversely, the spring 630 is compressed, and the force applied to the upper nest 300 by the spring 630 is released. Meanwhile, the lower nest 400 moves toward the handle 100 by the tension of the tension spring 530, and the second rib 520 and the first rib 510 are retracted inward, thereby completing the step of folding the umbrella frame 500 of the electric umbrella 10. Meanwhile, the lower pulley 720 drives the pull rope 730 to pull the upper nest 300, so that the upper nest 300 drives the outer tube 204 to move toward the umbrella handle 100, and the inner tube 202, the middle tube 206 and the outer tube 204 are sequentially sleeved from inside to outside, thereby completing the step of folding the umbrella rod of the electric umbrella 10.

Under the action of the tension spring 530, the second rib 520 slides in the opposite direction on the first rib 510, the pull rope 730 pulls the lower nest 400 and the upper nest 300 to slide on the outer tube 204 toward the umbrella head 100, so as to complete the step of folding the umbrella frame 500 of the electric umbrella 10, and meanwhile, the plurality of sleeves of the middle rod 200 are sleeved from inside to outside, so as to complete the step of folding the umbrella rod of the electric umbrella 10.

In the present embodiment, there is one upper pulley 710 and one lower pulley 720. One end of the pulling rope 730 is fixed to the head 100, and the other end of the pulling rope 730 passes through the second rod structure 620 and then sequentially passes around the upper pulley 710 and the lower pulley 720, and then the other end of the pulling rope 730 is fixed to the upper nest 300. Thus, the pulling rope 730 is divided into three segments. Correspondingly, in this embodiment, the middle tube 206 is also one, i.e. the middle rod 200 comprises three sleeves. Accordingly, the electric umbrella 10 is a triple-folding electric umbrella.

In other embodiments, when a four-fold electric umbrella or even a five-fold electric umbrella needs to be designed, the pull rope 730 is divided into four or even five segments by arranging the upper pulley 710 and the lower pulley 720 in corresponding numbers, and the middle rod 200 includes four, namely five sleeves.

In this embodiment, an end of the second rod 622 away from the compressed spring 624 is located outside the first rod structure 610. Thus, the second rod 622 is conveniently connected to the driving element 120.

In this embodiment, as shown in fig. 1 to 8 and fig. 16, the second rod 622 and the driving assembly 120 are detachably connected through the pluggable member 800, when the pluggable member 800 is pulled down, one end of the second rod 622 away from the pressure spring portion 624 becomes a free end, and the spring 630 compressed on the side of the pressure spring surface 6242 close to the second rod 622 can be released to drive the second rod 622 to move toward the upper nest 300, so that the foldable electric umbrella 10 is opened. When the electric umbrella 10 needs to be folded, the user can pull back the umbrella rod to fold the electric umbrella 10, and connect the second rod 622 and the driving component 120 through the pluggable component 800. Thus, when the electric umbrella 10 runs out of power and is not charged in time, the electric umbrella 10 can be opened and closed manually.

In this embodiment, the driving assembly 120 includes a motor 122, a master gear 124 and a slave gear 126, the master gear 124 is disposed on the output shaft 1222 of the motor 122, and the slave gear 126 is sleeved on an end of the second rod 622 away from the compression spring portion 624. The second rod 622 is detachably connected to the slave gear 126 via the pluggable member 800.

In this embodiment, the second rod 622 is provided with a slot for inserting and pulling the pluggable member 800. Specifically, in the present embodiment, a mounting portion 626 is provided at an end of the second rod 622 away from the pressure spring portion 624, and a notch is formed on the mounting portion 626.

As shown in fig. 17-19, in some embodiments, the first rod structure 610 is the same component as the inner tube 202, i.e., the first rod structure 610 is used in place of the inner tube 202. Thus, a larger diameter spring 630 may be used, thereby avoiding buckling of the spring 630 due to the stress on the protruding portion of the spring 630 and the large space between the outer tube 204 and the spring 630. Furthermore, the inner tube 202 is integrated with the first rod structure 610, which is less costly.

In this embodiment, the first shaft structure 610 (inner tube 202) is fixed to the umbrella head 100, and when the second shaft structure 620 rotates relative to the first shaft structure 610, the first shaft structure 610 is fixed relative to the umbrella head 100 and the second shaft structure 620 rotates relative to the umbrella head 100.

In the present embodiment, a limit step 2062 is formed inside the middle tube 206 closest to the inner tube 202, and the spring 630 may be compressed between the limit step 2062 and the compressed spring portion 624.

The above is only the optional embodiment of the present invention, and not therefore the limit of the patent scope of the present invention, all of which are in the concept of the present invention, the equivalent structure transformation of the content of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
