[0049] Unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in the utility model based on specific circumstances.

[0050] Example 1

[0051] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, this embodiment provides an umbrella handle, including a middle rod 1, a handle 3 and a power unit 4. The power unit 4 includes a screw rod 40 and a power part 41. The screw rod 40 is arranged in the middle rod 1, and the power part 41 drives the screw rod 40. The forward and reverse rotation of the screw rod 40 drives the umbrella slot to fold, thereby achieving the purpose of automatically opening and closing the umbrella surface, which is more convenient to use.

[0052] Furthermore, the umbrella handle also includes a socket 2, which is arranged below the middle rod 1 to connect to the middle rod 1, and the socket 2 has a socket portion 24; the handle 3 includes a handle base 30 and a handle cover 31, and a receiving cavity 303 for receiving the power component 41 is formed in the handle base 30, and the handle cover 31 closes the receiving cavity 303, and the handle cover 31 is provided with a through hole 311 that is engaged with the socket portion 24, and the power component 41 and the screw rod 40, the socket 2 and the handle cover 31, and the handle cover 31 and the handle base 30 are detachably connected.

[0053] It is easy to understand that when the middle rod is a multi-section middle rod, the socket 2 is connected to the lower end of the lowest middle rod.

[0054] Specifically, through hole 311 can be a regular circular hole or a special-shaped through hole. Special-shaped through holes can be polygonal, elliptical, or chamfered. Using special-shaped holes helps reduce the force on the fixing member, making it less likely to deform and easier to remove. The fixing member can be a pin or a bolt, or it can be connected by a stopper groove, securing the plug portion 24 to the through hole 311.

[0055] In one feasible embodiment, the irregularly shaped hole is a chamfered hole, and the mating surface between the socket 2 and the through hole 311 is a matching irregularly shaped plug portion 24, that is, the through hole 311 and the plug portion 24 have an irregular surface, or the through hole 311 is a round hole. The plug portion 24 is provided with a connector (not shown) that securely connects the handle cover 31 and the socket 2. This restricts the socket 2 from rotating relative to the handle cover 31, thereby increasing the stability of the connection between the socket 2 and the handle cover 31. If the connector can be a pin or a bolt, it can be sequentially passed through the first connecting hole 304 of the handle base 30, the second connecting hole 314 of the handle cover 31, and the third connecting hole 25 of the socket 2 before being secured to the handle base 30.

[0056] Furthermore, because the power member 41 and the screw rod 40, the socket 2 and the handle cover 31, and the handle cover 31 and the socket 30 are detachably connected, repair or replacement of the power member 41 is facilitated when it malfunctions or is damaged, without having to replace the entire handle 3, effectively saving on usage costs. Furthermore, the handle cover 31 and the socket 2 can be connected simply by connecting the through hole 311 in the handle cover 31 to the plug portion 24 of the socket 2. Thus, a single model of middle stick 1 can be used in place of different models of handles 3, providing flexibility in use and production, reducing production costs, and exhibiting excellent practicality.

[0057] like Figure 5 、 Figure 6 and Figure 8 As shown, in this embodiment, a connecting shaft 20 and a bearing 21 sleeved between the connecting shaft 20 and the inner hole of the connecting seat 2 are provided in the socket 2, and the power member 41 and the screw rod 40 are connected through the connecting shaft 20.

[0058] Specifically, the screw rod 40 is connected to the power member 41 through the connecting shaft 20, so that the screw rod 40 and the power member 41 are detachably connected. Specifically, one end of the screw rod 40 is fixedly connected to one end of the connecting shaft 20, and the other end of the connecting shaft 20 is provided with a special-shaped matching hole 201. The output end of the power member 41 is provided with a special-shaped matching portion 415 that is plugged into the matching hole 201. The connecting shaft 20 can be a coupling. Under the drive of the power member 41, the connecting shaft 20 can drive the screw rod 40 to rotate synchronously. In addition, through the provision of the bearing 21, friction between the connecting shaft 20 and the socket 2 can be avoided, and wear of the socket 2 can be avoided, thereby improving the flexibility of assembly and design. The power member 41 of the present utility model is separated from the screw rod 40, and the force points are on the connecting shaft 20 and the bearing 21, which can increase the service life of the power member 41.

[0059] like Figure 2 and Figure 5As shown, in this embodiment, a boss 302 is provided on the top surface of the handle base 30, and a groove 312 is provided on the bottom surface of the handle cover 31 to engage with the boss 302. The boss 302 and the top surface of the handle base 30 form a step 301 for the handle cover 31 to rest on. When assembling the handle cover 31 and the handle base 30, the boss 302 and the groove 312 can be used to achieve pre-positioning, and the handle cover 31 can be stably placed on the step 301 to facilitate subsequent assembly.

[0060] like Figure 2 As shown, this embodiment also includes a connecting member (not shown in the figure); a connecting portion 313 extending toward the handle base 30 is provided in the middle of the handle cover 31 to facilitate connection with the handle base 30; a first connecting hole 304 is provided on the handle base 30, and the connecting member passes through the connecting hole 304 and the connecting portion 313 and is provided on the socket 2. The connecting member can be a bolt or a pin, and a second connecting hole 314 is provided on the connecting portion 313 of the handle base 30 and the handle cover 31, which is aligned with the first connecting hole 304. A third connecting hole 25 is provided on the socket 2, which is aligned with the first connecting hole 304. The handle base 30, the handle cover 31 and the socket 2 can be locked and connected by the connecting member, thereby realizing the assembly of the umbrella handle.

[0061] like Figure 6 As shown, in this embodiment, the socket 2 includes a first clamping block 22 and a second clamping block 23 that are symmetrically clamped or separated below the center rod 1. The first clamping block 22 and / or the second clamping block 23 are provided with a positioning protrusion 222, and the second clamping block 23 and / or the first clamping block 22 are provided with a positioning groove 223 that cooperates with the positioning protrusion 222. In other words, the first clamping block 22 and the second clamping block 23 can be provided with staggered positioning protrusions 222 and positioning grooves 223 on their mating sides, so that the first clamping block 22 and the second clamping block 23 can be firmly clamped below the center rod 1.

[0062] Furthermore, the center rod 1 is provided with at least one latch 10, and the first and second clamping blocks 22, 23 are provided with a key 221 that engages with the latch 10. The engagement between the latch 10 and the key 221 further limits the vertical displacement of the socket 2, further securing the connection between the socket 2 and the center rod 1. The center rod 1 can be separated from the socket 2 by disassembling the socket 2 and separating the first and second clamping blocks 22, 23.

[0063] like Figure 4As shown, in this embodiment, the power member 41 includes a drive motor 411, a circuit board 412 electrically connected to the drive motor 411, a battery 413 electrically connected to the drive motor 411 and the circuit board 412, and a charging port 414 electrically connected to the circuit board 412. The charging port 414 is provided through the handle 30. The battery 413 is used to power the drive motor 411 and the components on the circuit board 412, and can be charged through the charging port 414.

[0064] like Figure 1 and Figure 4 As shown, in this embodiment, a tact switch 4121 is provided on the circuit board 412, and a button 305 for activating the tact switch 4121 is provided on the handle base 30. The tact switch 4121 can be a boat-type switch, or two push-button switches that control the forward or reverse rotation of the drive motor 411. By pressing the button on the tact switch 4121, the screw rod 40 is controlled to rotate forward or reverse, thereby driving the umbrella nest to move, thereby opening and closing the umbrella (the use of the screw rod to drive the pull rope to drive the umbrella nest up and down to achieve the opening and closing of the umbrella is a mature technology for electric umbrellas and will not be repeated here. Referring to the prior art, when the middle rod is a multi-section middle rod, the extension and retraction between the middle rods is achieved by a screw rod or a pull rope).

[0065] like Figure 2 and Figure 7 As shown, in this embodiment, a rope hole 306 is provided at the bottom of the handle base 30, and a hanging rope (not shown in the figure) is passed through the rope hole 306. The hanging rope is used to facilitate taking the umbrella, or the umbrella can be hung by the hanging rope, which has good practicality.
