In this embodiment, one end of the inner sleeve 202 is connected to the housing 110 of the umbrella head 100. Thus, when the middle rod 200 is pulled apart to form a long rod, the housing 110, the inner sleeve 202 and the outer sleeve 204 are sequentially arranged.

The upper nest 300 is disposed at an end of the outer sleeve 204 remote from the head 100.

The lower nest 400 is slidably disposed on the outer sleeve 204.

The umbrella frame 500 includes a first rib 510, a second rib 520, a tension spring 530, and a third rib 540. One end of the first rib 510 is connected to the upper nest 300. One end of the second rib 520 is connected to the lower nest 400, and the other end of the second rib 520 is slidably connected to the first rib 510. The two ends of the tension spring 530 are connected to the first rib 510 and the second rib 520, respectively. The third rib 540 is connected to the other end of the first rib 510.

The umbrella cloth is arranged on the umbrella frame 500.

In this embodiment, the umbrella rod assembly 12 further comprises an umbrella rod transmission assembly 600 and an umbrella rib transmission assembly 700, and the umbrella rod transmission assembly 600 is used in cooperation with the umbrella rib transmission assembly 700, so that when the umbrella unfolding button 112 is pressed, the driving assembly 120 can unfold the electric umbrella 10 through the umbrella rod transmission assembly 600 and the umbrella rib transmission assembly 700, and when the umbrella folding button 114 is pressed, the driving assembly 120 can fold the electric umbrella 10 through the umbrella rod transmission assembly 600 and the umbrella rib transmission 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.

More specifically, in this embodiment, the shaft driving assembly 600 applies force to the upper nest 300, and the upper nest 300 is disposed at an end of the outer sleeve 204 away from the umbrella head 100, so that the shaft driving assembly 600 indirectly applies force to the middle rod 200 through the upper nest 300.

In this embodiment, the umbrella shaft drive assembly 600 is located within the inner sleeve 202 as shown in FIGS. 3-7. The umbrella shaft driving assembly 600 includes a driving tube 610, a guide spring part 620, a spring 630 and a slider 640. One end of the drive tube 610 is rotatably connected to the umbrella head 100. The spring guide 620 is disposed at an end of the transmission tube 610 remote from the head 100. The guide spring portion 620 is provided with a guide spring passage 622. The spring 630 is slidably disposed on the transmission tube 610, and at least a portion of the coil 632 of the spring 630 is disposed in the spring guide passage 622. The sliding block 640 is slidably sleeved on the transmission tube 610 and located between the umbrella head 100 and the spring 630, and the sliding block 640 is connected with one end of the spring 630 near the umbrella head 100. The slider 640 can restrict the spring 630 from rotating relative to the guide spring part 620.

When the driving pipe 610 rotates, the driving pipe 610 drives the guide spring part 620 to rotate, and the slider 640 can limit the relative rotation between the spring 630 and the guide spring part 620, so that the spring 630 can slide on the driving pipe 610 while synchronously rotating with the guide spring part 620 to make a linear motion. The sliding block 640 is slidably sleeved on the transmission tube 610 and is connected to one end of the spring 630 near the umbrella head 100, so that the sliding block 640 can slide on the transmission tube 610 to linearly move while the spring 630 linearly moves.

When the driving pipe 610 rotates in the first direction, the spring 630 and the sliding block 640 slide on the driving pipe 610 towards the direction far away from the umbrella head 100, so that the spring 630 extends out (screws out) from the end of the spring guiding part 620 far away from the driving pipe 610 and applies force to the middle rod 200, and a plurality of sleeves of the middle rod 200 are pulled apart to form a long rod 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.

When the driving pipe 610 rotates in the second direction, the spring 630 and the slider 640 slide on the driving pipe 610 toward the direction close to the umbrella head 100, and the spring 630 protruding to the end of the guide spring part 620 away from the driving pipe 610 can be restored to the original position (screwed), thereby canceling the force applied to the middle stick 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.

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.

In the above-described stick drive assembly 600, the spring 630 is directly screwed in or out, and compression of the spring 630 is not required or is small. Therefore, when the transmission tube 610 is connected with the driving assembly 120 and the transmission tube 610 is driven to rotate by the driving assembly 120, the torque requirement on the driving assembly 120 is low. The driving assembly 120 with a smaller torque can be used to drive the transmission tube 610 to rotate, and the driving assembly 120 with a smaller torque has a smaller volume, so that the size of the umbrella head 100 can be reduced, and the electric umbrella 10 can be miniaturized. The spring 630 is directly rotated in or out, so that the electric umbrella 10 can be manually opened when the electric umbrella 10 in the folded state is not powered, and the electric umbrella 10 can be manually folded when the electric umbrella 10 in the opened state is not powered.

In this embodiment, when the guide spring passage 622 is one, a portion of one of the coils 632 is located within the guide spring passage 622 or all of the coils are located within the guide spring passage 622. When the spring guide passage 622 is plural, a coil 632 is disposed in each spring guide passage 622.

In the present embodiment, the spring 630 is multiple, multiple springs 630 are nested, and two adjacent coils 632 are respectively located on two different springs 630. That is, a plurality of springs 630 are nested to form a cylindrical elastic structure, and two adjacent springs 630 of the cylindrical elastic structure are springs 630 of two different springs 630. Specifically, in the present embodiment, the springs 630 are two, and the two springs 630 are nested such that one coil 632 of one spring 630 is between two adjacent coils 632 of the other spring 630.

Accordingly, in the present embodiment, the plurality of spring guide passages 622 is provided, and the number of the spring guide passages 622 is equal to or greater than the number of the springs 630, so as to ensure that at least a part of the coils 632 of each spring 630 can be disposed in the spring guide passages 622. Specifically, in the present embodiment, at least one coil 632 of each spring 630 is disposed in the spring guide passage 622.

Two springs 630 are provided and the two springs 630 nest. On the premise of realizing the same supporting force, two springs 630 with smaller wire diameter can be used to replace one spring 630 with larger wire diameter, and the two springs 630 with smaller wire diameter have better elasticity, which is more beneficial to manually folding or unfolding the electric umbrella 10.

In the present embodiment, the slider 640 restricts the relative rotation of the spring 630 and the guide spring part 620 by providing the slider 640 not to rotate.

In some embodiments, as shown in fig. 3-7, the outer wall of the slider 640 engages the inner wall of the inner sleeve 202 to limit rotation of the slider 640, while the inner wall of the slider 640 does not engage the outer wall of the drive tube 610 and does not limit rotation of the slider 640. That is, the slider block 640 cannot rotate within the inner sleeve 202, while the drive tube 610 may rotate within the slider block 640.

In this embodiment, the outer wall of the slider 640 and the inner wall of the inner sleeve 202 are both multi-surface structures, and the number of the outer wall of the slider 640 and the number of the inner wall of the inner sleeve 202 are the same and are arranged in a one-to-one correspondence. Specifically, in the present embodiment, the outer wall of the slider 640 has a regular hexahedral structure, and the inner wall of the inner sleeve 202 has a regular hexahedral structure.

Specifically, in the present embodiment, the outer wall of the driving pipe 610 may have a cylindrical structure or a multi-surface structure. The inner wall of the slider 640 is spaced apart from the outer wall of the driving pipe 610 by a first distance, and the inner wall of the spring 630 is spaced apart from the outer wall of the driving pipe 610 by a second distance. And the first distance and the second distance are both satisfied, the inner wall of the slider and the inner wall of the spring 630 do not interfere with the rotation of the driving pipe 610.

In the embodiment shown in fig. 3-7, the mid-stick 200 comprises two sleeves, in which case the mid-stick 200 is a mid-stick of a two-fold electric umbrella.

In some embodiments, as shown in fig. 8-11, the umbrella shaft drive assembly 600 includes a threaded tube 650, an outer drive tube 660, and a nut 670.

One end of the threaded pipe 650 is rotatably coupled to the umbrella head 100.

The drive tube 610 is slidably inserted into the end of the threaded tube 650 remote from the head 100. And the outer wall of the drive tube 610 cooperates with the inner wall of the threaded tube 650 to limit relative rotation of the drive tube 610 and the threaded tube 650. That is, when the threaded pipe 650 rotates, the driving pipe 610 is interlocked with the threaded pipe 650 to rotate in synchronization with the threaded pipe 650, so that the driving pipe 610 does not rotate with respect to the threaded pipe 650.

The outer transmission pipe 660 is slidably sleeved on the threaded pipe 650, and when the outer transmission pipe 660 slides on the threaded pipe 650, the transmission pipe 610 and the guide spring part 620 can be driven to slide.

The nut 670 is fitted over the threaded pipe 650 and threadedly engaged with the threaded pipe 650. The outer wall of the nut 670 mates with the inner wall of the inner sleeve 202 to allow the nut 670 to move over the threaded tube 650. The nut 670 is located between the umbrella head 100 and the outer transmission pipe 660, and the nut 670 is fixedly connected with one end of the outer transmission pipe 660 close to the umbrella head 100.

The spring 630 and the sliding block 640 are slidably sleeved on the outer transmission pipe 660, and the inner wall of the sliding block 640 is matched with the outer wall of the outer transmission pipe 660 to limit the rotation of the sliding block 640.

In the above structure, when the threaded pipe 650 rotates, the threaded pipe 650 drives the driving pipe 610 to rotate, and further drives the guide spring part 620 to rotate, and the slider 640 is restricted by the outer wall of the outer transmission pipe 660 and cannot rotate, so that the spring 630 can slide on the outer transmission pipe 660 while rotating synchronously with the guide spring part 620, and performs a linear motion. The sliding block 640 is slidably sleeved on the outer transmission pipe 660 and is connected with one end of the spring 630 close to the umbrella head 100, so that the sliding block 640 can slide on the outer transmission pipe 660 to perform linear motion while the spring 630 performs linear motion. In addition, when the threaded pipe 650 rotates, the outer wall of the nut 670 is engaged with the inner wall of the inner sleeve 202 so that the nut 670 can move on the threaded pipe 650, and thus the nut 670 can drive the outer transmission pipe 660 to slide on the threaded pipe 650 and perform a linear motion, and further the outer transmission pipe 660 can drive the transmission pipe 610 and the guide spring part 620 to slide and perform a linear motion.

In the above-described structure, since the outer transmission pipe 660, the transmission pipe 610, and the guide spring part 620 can linearly move, the linear movement displacement of the spring 630 is larger, and the present invention is suitably applied to the middle rod 200 having three or more folds.

In the present embodiment, when the middle stick 200 is a middle stick of an electric umbrella having three or more folds, and the middle stick 200 includes three or more sleeves, the middle tube 206 is located between the inner sleeve 202 and the outer sleeve 204. Wherein the number of the intermediate pipes 206 is 1 or more. In the embodiment shown in fig. 8-11, the number of intermediate pipes 206 is equal to 1, and the central rod 200 is the central rod of a tri-fold electric umbrella.

In this embodiment, the umbrella shaft assembly 600 further comprises a T-shaped cylindrical pin 680 and a bushing 690. The T-shaped cylindrical pin 680 is arranged on the transmission tube 610 in a penetrating mode, and the inner wall of the T-shaped cylindrical pin 680 is matched with the outer wall of the transmission tube 610 to limit the T-shaped cylindrical pin 680 to rotate.

The spring guide 620 is disposed through the T-shaped pin 680, and the head 682 of the T-shaped pin 680 is located between the spring guide 620 and the umbrella head 100.

The shaft sleeve 690 is inserted into the transmission tube 610, and one end of the shaft sleeve 690, which is far away from the umbrella head 100, is rotatably connected with the head end 682 of the T-shaped cylindrical pin 680. The end of the outer tube 660 away from the umbrella head 100 is sleeved on the shaft sleeve 690. Therefore, when the outer transmission pipe 660 slides on the threaded pipe 650, the transmission pipe 610 and the guide spring part 620 can be driven to slide.

In this embodiment, the outer wall of the driving pipe 610 and the inner wall of the threaded pipe 650 are both multi-surface structures, and the number of the surfaces of the outer wall of the driving pipe 610 is the same as the number of the surfaces of the inner wall of the threaded pipe 650, and the driving pipe 610 and the threaded pipe 650 are arranged in a one-to-one correspondence. Specifically, in the present embodiment, the outer wall of the driving pipe 610 has a regular five-sided structure, and the inner wall of the threaded pipe 650 has a regular five-sided structure.

In this embodiment, the outer wall of the nut 670 and the inner wall of the inner sleeve 202 are both multi-faceted, and the number of facets of the outer wall of the nut 670 is the same as the number of facets of the inner wall of the inner sleeve 202, and they are arranged in a one-to-one correspondence. Specifically, in the present embodiment, the outer wall of the nut 670 has a regular hexahedral structure, and the inner wall of the inner sleeve 202 has a regular hexahedral structure.

In this embodiment, the inner wall of the T-shaped cylindrical pin 680 and the outer wall of the transmission pipe 610 are both multi-surface structures, and the number of the surfaces of the inner wall of the T-shaped cylindrical pin 680 is the same as the number of the surfaces of the outer wall of the transmission pipe 610, and the T-shaped cylindrical pins are arranged in a one-to-one correspondence. Specifically, in the present embodiment, the inner wall of the T-shaped cylindrical pin 680 has a regular five-sided structure, and the outer wall of the transmission tube 610 also has a regular five-sided structure.

In the above structure, when the threaded pipe 650 rotates, the threaded pipe 650 drives the transmission pipe 610 to rotate, the transmission pipe 610 drives the T-shaped cylindrical pin 680 to rotate synchronously, so that the T-shaped cylindrical pin 680 drives the guide spring part 620 to rotate, and the slider 640 is limited by the outer wall of the outer transmission pipe 660 and cannot rotate, so that the spring 630 can slide on the outer transmission pipe 660 while rotating synchronously with the guide spring part 620 to do linear motion. The sliding block 640 is slidably sleeved on the outer transmission pipe 660 and is connected with one end of the spring 630 close to the umbrella head 100, so that the sliding block 640 can slide on the outer transmission pipe 660 to linearly move while the spring 630 linearly moves. In addition, when the threaded pipe 650 rotates, the outer wall of the nut 670 is matched with the inner wall of the inner sleeve 202, so that the nut 670 can move on the threaded pipe 650, the nut 670 can drive the outer transmission pipe 660 to slide on the threaded pipe 650, and perform linear motion, and then the outer transmission pipe 660 can drive the transmission pipe 610 and the guide spring part 620 to slide through the shaft sleeve 690 and perform linear motion.

In this embodiment, as shown in fig. 3-7, the electric umbrella 10 further comprises a rib driving assembly 700, and the rib driving assembly 700 cooperates with the umbrella shaft driving 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. One end of the pull rope 730 is fixed to the umbrella head 100, and the other end of the pull rope passes through the transmission tube 620, and then alternately passes 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 driving pipe 610 to rotate, the spring 630 is unscrewed, and after a force is applied to the upper nest 300, the upper nest 300 fixed on the outer sleeve 204 moves towards a direction far away from the umbrella head 100, so that the plurality of sleeves of the middle rod 200 are pulled apart to form a long rod connected end to end, and the step of opening the umbrella rod of the electric umbrella 10 to extend is completed. Meanwhile, as the upper nest 300 fixed on the outer sleeve 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 sleeve 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, the umbrella folding button 114 is pressed, the driving assembly 120 rotates reversely, the driving pipe 610 rotates, the spring 630 is screwed in, and the force applied to the upper nest 300 by the spring 630 is removed. 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 sleeve 204 to move toward the umbrella handle 100, and the inner sleeve 202, the middle tube 206 and the outer sleeve 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 towards the umbrella head 100 on the outer sleeve 204, 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 transmission tube 610 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.
