Description

Technical Field

[0002] After being folded, the folding umbrella is short in length and very convenient to carry and store, so it is very popular among users. However, traditional folding umbrellas usually require users to use both hands to open or fold them. When users hold objects in one hand and umbrella in the other hand, it is not convenient to open or fold the folding umbrella conveniently and quickly. In order to open or fold the folding umbrella more conveniently and quickly, people have designed electric umbrellas. Electric umbrellas usually include an umbrella pole device and an umbrella rib device, and the umbrella rib device is arranged on the umbrella pole device. When opening the electric umbrella, it is necessary to extend the umbrella pole device and open the umbrella rib device; when folding the electric umbrella, it is necessary to shorten the umbrella pole device and close the umbrella rib device.

[0003] In a traditional electric umbrella, when the electric umbrella is in a folded state, the spring is in a compressed state. When the electric umbrella needs to be opened, the compressed spring is released under the drive of the motor, so that the spring stretches, thereby opening the electric umbrella; when the electric umbrella needs to be folded, the spring is compressed again under the drive of the motor. Although the above-mentioned method of compressing and releasing the spring can realize the opening and folding of the electric umbrella, it has a high torque requirement for the motor and requires the use of a motor with a high torque.

[0057] The invention provides an electric umbrella.

[0058] In the embodiment of the present invention, Figure 1 As shown, the electric umbrella 10 includes an umbrella rod device 12 and an umbrella rib device 14, and the umbrella rib device 14 is arranged on the umbrella rod device 12. When the electric umbrella 10 is opened, the umbrella rod device 12 needs to be extended and the umbrella rib device 14 needs to be opened; when the electric umbrella 10 is folded, the umbrella rod device 12 needs to be shortened and the umbrella rib device 14 needs to be folded.

[0059] In this embodiment, the umbrella pole device 12 includes an umbrella head 100, a middle rod 200, an upper nest 300 and a lower nest 400. The umbrella rib device 14 includes an umbrella frame 500 and an umbrella cloth (not shown).

[0060] In this embodiment, if Figure 1-Figure 4 As shown, the umbrella head 100 includes a housing 110 and a driving assembly 120 disposed in the housing 110. The housing 110 is provided with an opening button 112 and a closing button 114, and both the opening button 112 and the closing button 114 are electrically connected to the driving assembly 120. When the opening button 112 is pressed, the output shaft of the driving assembly 120 rotates in one of the forward and reverse directions; when the closing button 114 is pressed, the output shaft of the driving assembly 120 rotates in the other of the forward and reverse directions. That is, after pressing the opening button 112 and pressing the closing button 114, the rotation direction of the output shaft of the driving assembly 120 is opposite.

[0061] In this embodiment, the umbrella head 100 further includes a battery (not shown) and an integrated circuit board (not shown) disposed in the housing 110. The battery is used to supply power to components such as the driving component 120 and the integrated circuit board, and the integrated circuit board is used to control the working mode of the driving component 120. The umbrella head 100 further includes a charging interface 130 disposed at the bottom of the housing 110, through which the battery can be charged.

[0062] like Figure 1-Figure 7 As shown, the middle rod 200 includes a plurality of sleeves connected from the inside to the outside, and the plurality of sleeves can be pulled apart to form a long rod connected end to end. The innermost sleeve of the middle rod 200 is the inner sleeve 202, and the outer sleeve 204 of the middle rod 200 is the outermost sleeve.

[0063] In this embodiment, one end of the inner sleeve 202 is connected to the shell 110 of the umbrella head 100. Thus, when the middle rod 200 is pulled apart to form a long rod, the shell 110, the inner sleeve 202 and the outer sleeve 204 are arranged in sequence.

[0064] The upper nest 300 is disposed at an end of the outer sleeve 204 away from the umbrella head 100 .

[0065] The lower nest 400 is slidably disposed on the outer sleeve 204 .

[0066] 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. Two ends of the tension spring 530 are respectively connected to the first rib 510 and the second rib 520. The third rib 540 is connected to the other end of the first rib 510.

[0067] The umbrella is arranged on the umbrella frame 500 .

[0068] In this embodiment, the umbrella pole device 12 also includes an umbrella pole transmission assembly 600 and an umbrella rib transmission assembly 700, and the umbrella pole transmission assembly 600 and the umbrella rib transmission assembly 700 are used in conjunction with each other, so that when the umbrella opening button 112 is pressed, the driving assembly 120 can open the electric umbrella 10 through the umbrella pole transmission assembly 600 and the umbrella rib transmission assembly 700, and when the umbrella closing button 114 is pressed, the driving assembly 120 can close the electric umbrella 10 through the umbrella pole transmission assembly 600 and the umbrella rib transmission assembly 700.

[0069] In this embodiment, the pole transmission assembly 600 is used to be arranged in the middle rod 200 of the electric umbrella 10. When the pole transmission assembly 600 applies force to the middle rod 200, the multiple sleeves of the middle rod 200 can be pulled apart to form a long rod connected end to end, so that the pole of the electric umbrella 10 is extended, that is, the step of extending the pole of the electric umbrella 10 is completed; when the force applied by the pole transmission assembly 600 to the middle rod 200 is cancelled, under the force of the tension spring 530 (which will be described in detail later), the multiple sleeves of the middle rod 200 can be connected from the inside to the outside, thereby completing the step of shortening the pole of the electric umbrella 10.

[0070] More specifically, in this embodiment, the umbrella rod transmission assembly 600 applies force to the upper nest 300 , and the upper nest 300 is disposed at one end of the outer sleeve 204 away from the umbrella head 100 , so that the umbrella rod transmission assembly 600 indirectly applies force to the middle rod 200 through the upper nest 300 .

[0071] In this embodiment, if Figure 3-Figure 7 As shown, the umbrella rod transmission assembly 600 is located in the inner sleeve 202. The umbrella rod transmission assembly 600 includes a transmission tube 610, a spring guide portion 620, a spring 630 and a slider 640. One end of the transmission tube 610 is rotatably connected to the umbrella head 100. The spring guide portion 620 is disposed at one end of the transmission tube 610 away from the umbrella head 100. The spring guide portion 620 is provided with a spring guide passage 622. The spring 630 is slidably sleeved on the transmission tube 610, and at least part of the spring coil 632 of the spring 630 is disposed in the spring guide passage 622. The slider 640 is slidably sleeved on the transmission tube 610 and is located between the umbrella head 100 and the spring 630, and the slider 640 is connected to one end of the spring 630 close to the umbrella head 100. The slider 640 can limit the relative rotation of the spring 630 and the spring guide portion 620.

[0072] When the transmission tube 610 rotates, the transmission tube 610 drives the spring guide portion 620 to rotate, and the slider 640 can limit the relative rotation of the spring 630 and the spring guide portion 620, so that the spring 630 can slide on the transmission tube 610 and perform linear motion while rotating synchronously with the spring guide portion 620. In addition, the slider 640 is slidably sleeved on the transmission tube 610 and connected to one end of the spring 630 close to the umbrella head 100, so that when the spring 630 performs linear motion, the slider 640 can also slide on the transmission tube 610 and perform linear motion.

[0073] When the transmission tube 610 rotates in the first direction, the spring 630 and the slider 640 slide on the transmission tube 610 in a direction away from the umbrella head 100, so that the spring 630 extends (rotates out) from the end of the spring guide portion 620 away from the transmission tube 610, and applies force to the middle rod 200, so that the multiple sleeves of the middle rod 200 are pulled apart to form a long rod connected end to end. In this way, the pole of the electric umbrella 10 is extended, that is, the step of extending the pole of the electric umbrella 10 is completed.

[0074] When the transmission tube 610 rotates in the second direction, the spring 630 and the slider 640 slide on the transmission tube 610 toward the umbrella head 100, and the spring 630 extending to the end of the spring guide portion 620 away from the transmission tube 610 can be restored to the initial position (screwed in), thereby canceling the force applied by the spring 630 to the middle rod 200. In this way, under the action of other components, the multiple sleeves of the middle rod 200 can be connected from the inside to the outside, so as to complete the step of shortening the umbrella pole of the electric umbrella 10.

[0075] 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.

[0076] In the above-mentioned umbrella pole transmission assembly 600, the spring 630 is directly screwed in or out, and there is no need to compress the spring 630 or the degree of compression of the spring 630 is small. Therefore, when the transmission tube 610 is connected to the drive assembly 120 and the transmission tube 610 is driven to rotate by the drive assembly 120, the torque requirement of the drive assembly 120 is relatively low. A drive assembly 120 with a smaller torque can be used to drive the transmission tube 610 to rotate, and the volume of the drive assembly 120 with a smaller torque is usually smaller, which can reduce the size of the umbrella head 100 and make the electric umbrella 10 miniaturized. In addition, the spring 630 is directly screwed in or out, and when the electric umbrella 10 in the folded state is out of power, the electric umbrella 10 can be manually opened, and when the electric umbrella 10 in the open state is out of power, the electric umbrella 10 can be manually folded.

[0077] In this embodiment, when there is one spring guide passage 622, a part of one spring coil 632 is located in the spring guide passage 622 or the whole of one spring coil 632 is located in the spring guide passage 622. When there are multiple spring guide passages 622, one spring coil 632 is correspondingly disposed in each spring guide passage 622.

[0078] In this embodiment, there are multiple springs 630, the multiple springs 630 are nested, and two adjacent spring coils 632 are respectively located on two different springs 630. That is, multiple springs 630 are nested to form a cylindrical elastic structure, and the two adjacent springs 630 of the cylindrical elastic structure are springs 630 of two different springs 630. Specifically, in this embodiment, there are two springs 630, and the two springs 630 are nested, so that a spring coil 632 of another spring 630 is located between two adjacent spring coils 632 of one spring 630.

[0079] Accordingly, in this embodiment, there are multiple spring guide passages 622, and the number of spring guide passages 622 is greater than or equal to the number of springs 630, so as to ensure that at least part of the spring coil 632 of each spring 630 can be disposed in the spring guide passage 622. Specifically, in this embodiment, at least one spring coil 632 of each spring 630 is disposed in the spring guide passage 622.

[0080] Two springs 630 are provided, and the two springs 630 are nested. Under the premise of achieving the same supporting force, two springs 630 with smaller wire diameters can be used to replace one spring 630 with a larger wire diameter, and the two springs 630 with smaller wire diameters have better elasticity, which is more conducive to manually folding or opening the electric umbrella 10.

[0081] In this embodiment, the slider 640 is set not to rotate, so as to limit the relative rotation of the spring 630 and the spring guide portion 620 through the slider 640 .

[0082] In some embodiments, Figure 3-Figure 7 As shown, the outer wall of the slider 640 cooperates with the inner wall of the inner sleeve 202 to limit the rotation of the slider 640, while the inner wall of the slider 640 does not cooperate with the outer wall of the transmission tube 610 and cannot limit the rotation of the slider 640. That is, the slider 640 cannot rotate in the inner sleeve 202, while the transmission tube 610 can rotate in the slider 640.

[0083] In this embodiment, the outer wall of the slider 640 and the inner wall of the inner sleeve 202 are both multi-faceted structures, and the number of faces of the outer wall of the slider 640 is the same as the number of faces of the inner wall of the inner sleeve 202, and they are arranged in a one-to-one correspondence. Specifically, in this embodiment, the outer wall of the slider 640 is a regular six-faceted structure, and the inner wall of the inner sleeve 202 is also a regular six-faceted structure.

[0084] Specifically, in this embodiment, the outer wall of the transmission tube 610 may be a cylindrical structure or a multi-faceted structure. The inner wall of the slider 640 is spaced apart from the outer wall of the transmission tube 610 by a first distance, and the inner wall of the spring 630 is spaced apart from the outer wall of the transmission tube 610 by a second distance. When both the first distance and the second distance are satisfied, the inner wall of the slider and the inner wall of the spring 630 do not interfere with the rotation of the transmission tube 610.

[0085] exist Figure 3-Figure 7 In the illustrated embodiment, the middle rod 200 includes two sleeves. In this case, the middle rod 200 is a middle rod of a two-fold electric umbrella.

[0086] In some embodiments, Figure 8-Figure 11 As shown, the umbrella pole transmission assembly 600 includes a threaded tube 650 , an outer transmission tube 660 and a nut 670 .

[0087] One end of the threaded tube 650 is rotatably connected to the umbrella head 100 .

[0088] The transmission tube 610 is slidably inserted into the end of the threaded tube 650 away from the umbrella head 100. The outer wall of the transmission tube 610 cooperates with the inner wall of the threaded tube 650 to limit the relative rotation of the transmission tube 610 and the threaded tube 650. That is, when the threaded tube 650 rotates, the transmission tube 610 and the threaded tube 650 are linked to each other and rotate synchronously with the threaded tube 650, so that the transmission tube 610 does not rotate relative to the threaded tube 650.

[0089] The outer transmission tube 660 is slidably sleeved on the threaded tube 650 , and when the outer transmission tube 660 slides on the threaded tube 650 , it can drive the transmission tube 610 and the guide spring portion 620 to slide.

[0090] The nut 670 is sleeved on the threaded tube 650 and is threadedly connected to the threaded tube 650. The outer wall of the nut 670 cooperates with the inner wall of the inner sleeve 202 so that the nut 670 can move on the threaded tube 650. The nut 670 is located between the umbrella head 100 and the outer transfer tube 660, and the nut 670 is fixedly connected to one end of the outer transfer tube 660 close to the umbrella head 100.

[0091] The spring 630 and the slider 640 are both slidably mounted on the outer tube 660 , and the inner wall of the slider 640 cooperates with the outer wall of the outer tube 660 to limit the slider 640 from rotating.

[0092] In the above structure, when the threaded tube 650 rotates, the threaded tube 650 drives the transmission tube 610 to rotate, and then drives the guide spring part 620 to rotate, while the slider 640 is restricted by the outer wall of the outer tube 660 and cannot rotate, so that the spring 630 can slide on the outer tube 660 and perform linear motion while rotating synchronously with the guide spring part 620. In addition, the slider 640 is slidably sleeved on the outer tube 660 and connected to the end of the spring 630 close to the umbrella head 100, so that when the spring 630 performs linear motion, the slider 640 can also slide on the outer tube 660 and perform linear motion. In addition, when the threaded tube 650 rotates, the outer wall of the nut 670 cooperates with the inner wall of the inner sleeve 202 so that the nut 670 can move on the threaded tube 650, so that the nut 670 can drive the outer tube 660 to slide on the threaded tube 650 and perform linear motion, and then the outer tube 660 can drive the transmission tube 610 and the guide spring part 620 to slide and perform linear motion.

[0093] In the above structure, since the outer transmission tube 660, the transmission tube 610 and the spring guide part 620 can all perform linear motion, the linear motion displacement of the spring 630 is larger, and it is suitable for application in the middle rod 200 that is folded three times or more.

[0094] In this embodiment, when the middle rod 200 is a middle rod of an electric umbrella that can be folded three or more times, and the middle rod 200 includes three or more sleeves, the middle tube 206 is located between the inner sleeve 202 and the outer sleeve 204. The number of the middle tubes 206 is greater than or equal to 1. Figure 8-Figure 11 In the illustrated embodiment, the number of the intermediate tubes 206 is equal to 1, and the middle rod 200 is the middle rod of a three-fold electric umbrella.

[0095] In this embodiment, the umbrella rod transmission assembly 600 further includes a T-shaped cylindrical pin 680 and a shaft sleeve 690. The T-shaped cylindrical pin 680 is passed through the transmission tube 610, and the inner wall of the T-shaped cylindrical pin 680 cooperates with the outer wall of the transmission tube 610 to limit the rotation of the T-shaped cylindrical pin 680.

[0096] The spring guide portion 620 is passed through the T-shaped cylindrical pin 680 , and the head end 682 of the T-shaped cylindrical pin 680 is located between the spring guide portion 620 and the umbrella head 100 .

[0097] The shaft sleeve 690 is inserted into the transmission tube 610, and the end of the shaft sleeve 690 away from the umbrella head 100 is rotatably connected to the head end 682 of the T-shaped cylindrical pin 680. The end of the outer transmission tube 660 away from the umbrella head 100 is sleeved on the shaft sleeve 690. Therefore, when the outer transmission tube 660 slides on the threaded tube 650, it can drive the transmission tube 610 and the guide spring part 620 to slide.

[0098] In this embodiment, the outer wall of the transmission tube 610 and the inner wall of the threaded tube 650 are both multi-faceted structures, and the number of faces of the outer wall of the transmission tube 610 is the same as the number of faces of the inner wall of the threaded tube 650, and they are arranged in a one-to-one correspondence. Specifically, in this embodiment, the outer wall of the transmission tube 610 is a regular five-faceted structure, and the inner wall of the threaded tube 650 is also a regular five-faceted structure.

[0099] In this embodiment, the outer wall of the nut 670 and the inner wall of the inner sleeve 202 are both multi-faceted structures, and the number of faces of the outer wall of the nut 670 is the same as the number of faces of the inner wall of the inner sleeve 202, and they are arranged in a one-to-one correspondence. Specifically, in this embodiment, the outer wall of the nut 670 is a regular hexagonal structure, and the inner wall of the inner sleeve 202 is also a regular hexagonal structure.

[0100] In this embodiment, the inner wall of the slider 640 and the outer wall of the external transfer tube 660 are both multi-faceted structures, and the number of faces of the inner wall of the slider 640 is the same as the number of faces of the outer wall of the external transfer tube 660, and they are arranged in a one-to-one correspondence. Specifically, in this embodiment, the inner wall of the slider 640 is a regular five-faceted structure, and the outer wall of the external transfer tube 660 is also a regular five-faceted structure.

[0101] In this embodiment, the inner wall of the T-shaped cylindrical pin 680 and the outer wall of the transmission tube 610 are both multi-faceted structures, and the number of faces of the inner wall of the T-shaped cylindrical pin 680 is the same as the number of faces of the outer wall of the transmission tube 610, and they are arranged one by one. Specifically, in this embodiment, the inner wall of the T-shaped cylindrical pin 680 is a regular five-faceted structure, and the outer wall of the transmission tube 610 is also a regular five-faceted structure.

[0102] In the above structure, when the threaded tube 650 rotates, the threaded tube 650 drives the transmission tube 610 to rotate, and the transmission tube 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 restricted by the outer wall of the outer tube 660 and cannot rotate, so that the spring 630 can slide on the outer tube 660 and perform linear motion while rotating synchronously with the guide spring part 620. In addition, the slider 640 is slidably sleeved on the outer tube 660 and connected to the end of the spring 630 close to the umbrella head 100, so that when the spring 630 performs linear motion, the slider 640 can also slide on the outer tube 660 and perform linear motion. In addition, when the threaded tube 650 rotates, the outer wall of the nut 670 cooperates with the inner wall of the inner sleeve 202 so that the nut 670 can move on the threaded tube 650, so that the nut 670 can drive the outer transfer tube 660 to slide on the threaded tube 650 and make a linear motion, and then the outer transfer tube 660 can drive the transmission tube 610 and the guide spring part 620 to slide through the shaft sleeve 690 and make a linear motion.

[0103] In this embodiment, if Figure 3-Figure 7 As shown, the electric umbrella 10 further includes an umbrella rib transmission assembly 700, which cooperates with the umbrella rod transmission assembly 600. When the umbrella rod transmission assembly 600 completes the step of extending the umbrella rod of the electric umbrella 10, the umbrella rib transmission assembly 700 opens the umbrella frame 500 of the electric umbrella 10; when the force applied by the umbrella rod transmission assembly 600 to the middle rod 200 is removed, under the action of the tension spring 530, the umbrella rib transmission assembly 700 closes the umbrella frame 500 of the electric umbrella 10, and the multiple sleeves of the middle rod 200 are connected from the inside to the outside, completing the step of shortening the umbrella rod of the electric umbrella 10.

[0104] In this embodiment, the umbrella rib transmission assembly 700 includes at least one upper pulley 710, at least one lower pulley 720, and a pull rope 730. The upper pulley 710 is disposed on the upper nest 300. The lower pulley 720 is disposed on the lower nest 400. One end of the pull rope 730 is fixed to the umbrella head 100, and the other end passes through the transmission tube 620, 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.

[0105] When the electric umbrella 10 is used, after pressing the umbrella opening button 112, the driving assembly 120 rotates, driving the transmission tube 610 to rotate, and the spring 630 is screwed out. After applying force to the upper nest 300, the upper nest 300 fixed on the outer sleeve 204 moves in a direction away from the umbrella head 100, so that the multiple sleeves of the middle rod 200 are pulled apart to form a long rod connected end to end, completing the step of extending the umbrella rod of the electric umbrella 10. At the same time, since the upper nest 300 fixed on the outer sleeve 204 moves in a direction away from the umbrella head 100 relative to the umbrella head 100, at this time, the pull rope 730 will pull the lower nest 400 to slide on the outer sleeve 204 toward the upper nest 300, driving the second umbrella rib 520 to slide on the first umbrella rib 510, thereby opening the umbrella frame 500, completing the step of opening the umbrella frame 500 of the electric umbrella 10. At this time, the electric umbrella 10 is in an open state, and the tension spring 530 is in a compressed state.

[0106] Then, the umbrella folding button 114 is pressed, and the driving assembly 120 rotates in the opposite direction, driving the transmission tube 610 to rotate, and the spring 630 is screwed in, canceling the force applied by the spring 630 on the upper nest 300. At the same time, the lower nest 400 moves toward the umbrella handle 100 by the tension of the tension spring 530, and retracts the second umbrella rib 520 and the first umbrella rib 510 inward, completing the step of folding the umbrella frame 500 of the electric umbrella 10. At the same time, 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, so that the inner sleeve 202, the middle tube 206 and the outer sleeve 204 are sequentially sleeved from the inside to the outside, completing the step of folding the umbrella pole of the electric umbrella 10.

[0107] Under the action of the tension spring 530, the second rib 520 slides in the opposite direction on the first rib 510, and the pull rope 730 pulls the lower nest 400 and the upper nest 300 to slide on the outer sleeve 204 toward the umbrella head 100, completing the step of folding the umbrella frame 500 of the electric umbrella 10. At the same time, the multiple sleeves of the middle rod 200 are connected from the inside to the outside, completing the step of folding the umbrella pole of the electric umbrella 10.

[0108] In this embodiment, the upper pulley 710 and the lower pulley 720 are both one. One end of the pull rope 730 is fixed to the umbrella head 100, and the other end passes through the transmission tube 610, and then passes around the upper pulley 710 and the lower pulley 720 in sequence, and then the other end of the pull rope 730 is fixed to the upper nest 300. In this way, the pull rope 730 is divided into three sections. Correspondingly, in this embodiment, the middle tube 206 is also one, that is, the middle rod 200 includes three sleeves. Accordingly, the electric umbrella 10 is a three-fold electric umbrella.

[0109] In other embodiments, when it is necessary to design a four-fold electric umbrella or even a five-fold electric umbrella, the pull rope 730 is divided into four sections or even five sections by setting a corresponding number of upper pulleys 710 and lower pulleys 720, and the middle rod 200 includes four or five sleeves.

[0110] In this embodiment, if Figure 4 As shown, the driving assembly 120 includes a motor 122, a main gear 124, a slave gear 126 and a gearbox. The main gear 124 is disposed on the output shaft of the motor 122. The slave gear 126 is sleeved on an end of the transmission tube 610 away from the spring guide portion 620. The speed change gear of the gearbox is meshed with the main gear 124 and the slave gear 126 respectively.

[0111] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
