[0040] The present utility model provides a structure of an umbrella rod.

[0041] Please refer to Figures 1 to 6 As shown, in an embodiment of the present utility model, the structure of the umbrella rod includes: an umbrella head 100, a middle rod 200, a lower nest 300, and a driving mechanism 400. Among them, the middle rod 200 is hollow and connected to the umbrella head 100. The lower nest 300 is sleeved on the outer periphery of the middle rod 200 and slides along the middle rod 200. The driving mechanism 400 includes a driving rod 410, a moving block 420, and a transmission member 430. The transmission member 430 is a ring structure and is wound with a first pulley 440 and a second pulley 450. The first pulley 440 is provided on the umbrella head 100 or at one end of the middle rod 200 close to the umbrella head 100. The second pulley 450 is close to the end of the middle rod 200 away from the umbrella head 100. The transmission member 430 forms a first section 431 and a second section 432 with opposite transmission directions between the first pulley 440 and the second pulley 450. The first section 431 is connected to the lower nest 300, and the second section 432 is connected to the moving block 420. The moving block 420 is arranged inside the middle rod 200 and slides along the middle rod 200, and the moving block 420 is rotatably connected to the driving rod 410. The driving rod 410 rotates to drive the moving block 420 to move along the driving rod 410, so that the transmission member 430 rotates, and then drives the lower nest 300 to approach or move away from the umbrella head 100.

[0042] In this embodiment, the middle rod 200 adopts a tubular structure, so that the inside of the middle rod 200 is hollow. One end of the middle rod 200 is fixedly connected to the umbrella head 100, and the lower nest 300 is sleeved on the outer periphery of the middle rod 200 and slides along the middle rod 200. The driving rod 410 of the driving mechanism 400 rotates to drive the moving block 420 to move. In a specific implementation process, the driving rod 410 is a threaded rod, and the moving block 420 is threadedly connected to the driving rod 410, thereby realizing the rotation of the driving rod 410 to drive the moving block 420 to move. In another specific implementation process, the driving rod 410 can drive the moving block 420 to move through a transmission structure such as a gear rack or a transmission belt, which will not be described in detail here. In still another specific implementation process, the driving rod 410 includes a fixed tube body and a rectangular spring. Among them, the rectangular spring is fixedly sleeved on the outer periphery of the fixed tube body, so that the driving rod 410 forms a threaded tube, and the moving block 420 is rotatably sleeved on the threaded tube. In this way, the rotation of the driving rod 410 can drive the moving block 420 to move. In this embodiment, the moving block 420 is rotatably sleeved on the driving rod 410, and moreover, the moving block 420 is also slidably connected inside the middle rod 200, and the middle rod 200 restricts the rotation of the moving block 420. In this way, the rotation of the driving rod 410 can drive the moving block 420 to move.

[0043] The first pulley 440 and the second pulley 450 are respectively connected to a rotating shaft, and the first pulley 440 is rotatably connected to the umbrella head 100 through the rotating shaft, or the first pulley 440 is rotatably connected to the end of the middle rod 200 close to the umbrella head 100 through the rotating shaft, that is, the first pulley 440 can be installed in the umbrella head 100, or on the middle rod 200. The second pulley 450 is close to the end of the middle rod 200 away from the umbrella head 100. In the specific implementation process, the second pulley 450 can be installed on the middle rod 200 or on other structures, and the second pulley 450 is in the direction of the first pulley 440 away from the umbrella head 100. The distance between the first pulley 440 and the second pulley 450 ensures that the transmission member 430 drives the lower nest 300 to move a distance that can fully open and fold the umbrella. The transmission member 430 is wound around the first pulley 440 and the second pulley 450. The transmission member 430 can be a structure such as a transmission belt or a pull rope. The transmission directions of the first section 431 and the second section 432 between the first pulley 440 and the second pulley 450 are opposite. The first section 431 is connected to the lower nest 300, and the second section 432 is connected to the moving block 420. The driving rod 410 drives the moving block 420 to move, and the moving block 420 drives the lower nest 300 to move through the transmission member 430. Specifically, when the driving rod 410 rotates to drive the moving block 420 to move in a direction away from the umbrella head 100, the lower nest 300 is driven to move along the middle rod 200 toward the umbrella head 100 through the transmission member 430, thereby realizing the folding and closing of the umbrella. When the driving rod 410 rotates in the opposite direction to drive the moving block 420 to move in a direction close to the umbrella head 100, the lower nest 300 moves along the middle rod 200 in a direction away from the umbrella head 100, thereby realizing the opening of the umbrella.

[0044] The technical solution of the utility model adopts a driving mechanism 400 to automatically control and drive the lower nest 300 to move along the middle rod 200 to open or close the umbrella.

The driving rod 410 is rotatably connected to the moving block 420, and the moving block 420 is also arranged inside the middle rod 200 and moves along the middle rod 200. The driving rod 410 rotates to drive the moving block 420 to move along the driving rod 410, and then drives the lower nest 300 to move through the transmission member 430 to realize automatic opening or closing of the umbrella, without manually operating the lower nest 300 to move to open or close the umbrella, and the driving mechanism 400 is simple in structure and easy to assemble, so that the umbrella rod structure has the characteristics of simple structure, convenient use, and low assembly cost. It should be noted that the transmission distance between the first segment 431 and the second segment 432 is required to ensure that the movement position of the lower nest 300 on the middle rod 200 ensures that the umbrella can be fully opened and closed.

[0045] refer toFigure 3 As shown, further, the first body section 431 is provided with a first connecting block 433, the lower nest 300 is provided with a first connecting opening 310, the first connecting block 433 is fixedly arranged in the first connecting opening 310, the second body section 432 is provided with a second connecting block 434, the moving block 420 is provided with a second connecting opening 421, and the second connecting block 434 is fixedly arranged in the second connecting opening 421.

[0046] The first body section 431 is fixedly connected with a first connecting block 433, and the second body section 432 is connected with a second connecting block 434. In one embodiment, the first connecting block 433 is fixedly connected with the first body section 431, and the second connecting block 434 is fixedly connected with the second body section 432. The connection between the transmission member 430 and the two connecting blocks, specifically, that is, the connection between the first connecting block 433 and the first body section 431, and the connection between the second connecting block 434 and the second body section 432. Correspondingly, on the one hand, it can be fixedly connected by means such as bonding or injection molding. When the transmission member 430 is a pull rope, the pull rope can also be fixedly connected by tying a knot. On the other hand, the transmission member 430 and the two connecting blocks can be an integral structure. In this embodiment, the first connecting block 433 is in a spherical or block-like structure, etc., and protrudes from the outer peripheral wall of the first body section 431, and the second connecting block 434 is in a spherical or block-like structure, etc., and protrudes from the outer peripheral wall of the second body section 432. In the specific implementation process, the first connecting opening 310 is opened on the inner wall of the lower nest 300 facing the middle rod 200 or penetrates through the lower nest 300, the first connecting block 433 is fixedly accommodated in the first connecting opening 310, the outer wall of the moving block 420 is provided with a second connecting opening 421, and the second connecting block 434 is fixedly accommodated in the second connecting opening 421. In this way, the moving block 420 drives the transmission member 430 to rotate through the second connecting block 434, and the transmission member 430 drives the lower nest 300 to move through the first connecting block 433.

[0047] In one embodiment, the umbrella rod structure further includes an upper nest 500, the upper nest 500 is arranged at one end of the middle rod 200 away from the umbrella head 100, the second pulley 450 is rotatably connected with the upper nest 500, a notch 210 is opened at one end of the middle rod 200 close to the upper nest 500, the second pulley 450 is also located at the notch 210, the first body section 431 is arranged outside the middle rod 200, and the second body section 432 is arranged inside the middle rod 200.

[0048] In the specific implementation process, the upper nest 500 includes a shell 510 and a connecting seat 520. Specifically, the middle rod 200 is sleeved on the connecting seat 520, and the shell 510 is sleeved on the connecting seat 520 and fixedly connected to the connecting seat 520. The connecting seat 520 has a rotating groove, and the second pulley 450 is rotatably connected to the connecting seat 520 through a rotating shaft, and the second pulley 450 rotates in the rotating groove. The middle rod 200 has a notch 210 corresponding to the rotating groove, so that the first section 431 can extend to the outside of the middle rod 200 and connect to the lower nest 300, and the second section 432 extends to the inside of the middle rod 200 and connects to the moving block 420.

[0049] Furthermore, a first groove 220 is provided on the outer wall of the middle rod 200 and is used to accommodate the first section 431. A second groove 422 is provided on the outer wall of the moving block 420 and is used to accommodate the second section 432. An avoidance groove 423 is also provided at the bottom of the second groove 422 and is used to avoid the second section 432. The avoidance groove 423 is connected to the second connecting port 421. The first groove 220 and the second groove 422 are correspondingly arranged, and the side of the middle rod 200 away from the first groove 220 extends into the second groove 422.

[0050] The outer wall of the middle rod 200 is recessed inward to form a first groove 220. The length direction of the first groove 220 is consistent with the axial direction of the middle rod 200. In order to prevent the first section 431 from interfering with the sliding of the lower nest 300 along the middle rod 200, in the specific implementation process, the first section 431 is located in the first groove 220. It can be understood that the first connecting block 433 extends from the first groove 220 and connects the lower nest 300. The moving block 420 is located inside the middle rod 200, and the outer wall of the moving block 420 is in contact with the inner wall of the middle rod 200. Accordingly, the outer wall of the moving block 420 is provided with a second groove 422, and the second groove 422 is arranged corresponding to the first groove 220. The bottom of the first groove 220 facing the side of the moving block 420 is also located in the second groove 422. In this way, the inner wall of the middle rod 200 can also limit the displacement of the second segment 432 and the second connecting block 434 to prevent the second connecting block 434 from falling off from the moving block 420, thereby improving the stability of the connection between the second segment 432 and the moving block 420. In addition, in order to prevent the second segment 432 and the second connecting block 434 from interfering with the sliding of the moving block 420 in the middle rod 200, the bottom of the second groove 422 is further provided with an avoidance groove 423 to accommodate the second segment 432, and the second connecting port 421 is provided at the bottom of the second groove 422 and communicates with the avoidance groove 423 to accommodate the second connecting block 434.

In the specific implementation process, the rotation of the moving block 420 can be restricted by the cooperation of a limiting block and a limiting groove or other means between the middle rod 200 and the moving block 420. Specifically, the inner wall of the middle rod 200 and the outer wall of the moving block 420 are both multi-faceted structures, and the number of faces of the outer wall of the moving block 420 is the same as that of the inner wall of the middle rod 200, and they are arranged in one-to-one correspondence. Specifically, in this embodiment, the outer wall of the moving block 420 and the inner wall of the middle rod 200 are both regular hexahedron structures, so that the middle rod 200 can limit the rotation of the moving block 420.

[0052] In one embodiment, the driving mechanism 400 further includes a power assembly 600. The power assembly 600 is disposed inside the umbrella head 100. The power assembly 600 includes a motor 610 and a reduction device 620.
