Description

Technical Field

[0001] The invention belongs to the technical field of wearable devices, and in particular relates to an explosion-proof wire winding mechanism and a wearable device. Background Art

[0002] The winding mechanism consists of a central shaft and a winding drum (also called a reel) mounted on the central shaft. When the central shaft rotates, the winding drum will wind up or release the wire or rope connected to it. The rotation of the central shaft can be manually operated or automatically controlled by an electric motor or hydraulic system.

[0003] The winding mechanism in the prior art usually consists of five parts: a power source, a transmission system, a winding shaft, a winding control device, and an auxiliary device. However, in the design process, due to the uncertainty of the position of the rope or cable when winding or the inconsistent tension it receives, it is easy for the wire harness to be entangled and knotted. The Chinese patent with the publication number CN118519234A discloses an optical cable offline device, which adopts a gear rack design with a locking mechanism on the winding device. When wiring, the rack can be used to drive the gear to rotate to tighten the mainspring. After the wire is installed, the meshing part of the rack and the gear is released to release the mainspring to tighten the wire. This can ensure that the tension of the optical cable is consistent each time, avoiding the phenomenon of knotting and winding. During maintenance, the wire can also be loosened by reverse operation, which improves the efficiency of wiring and maintenance. This wire management device can avoid the problem of knotting and winding in the winding process to a certain extent, but in terms of anti-explosion wire, a constraint cylinder is used to prevent the wire from exploding, and the anti-explosion wire effect is poor.

[0048] The driving gear 13 is fixed to the output shaft of the motor 12 , and the driven gear 14 is fixed to the second end of the rotating shaft 2 . The driving gear 13 is meshed with the driven gear 14 .

[0049] In the above embodiment, the user can adjust the rotation speed of the motor 12 to adjust the rotation speed of the rotating shaft 2 to adjust the winding / unwinding speed of the winding rod 1, and the degree of automation is relatively high.

[0050] Optionally, the number of the wiring harnesses 3 is two, and the two wiring harnesses 3 are respectively located at the upper and lower ends of the winding rod 1; the number of the first groove 81, the second groove 91, the third groove 101 and the fourth groove 111 are two, and the two first grooves 81 are respectively located at the upper and lower ends of the first gear 51; the two second grooves 91 are respectively located at the upper and lower ends of the second gear 61; the two third grooves 101 are respectively located at the upper and lower ends of the third gear; the two fourth grooves 111 are respectively located at the upper and lower ends of the fourth gear.

[0051] In the above embodiment, it helps to ensure the safety and stability of winding or releasing the wire harness 3 of the anti-explosion wire winding mechanism.

[0053] In the above embodiment, the first main gear 41 is meshed with the first gear 51, and at the same time, the second main gear 42 is connected to the second gear 61 through the transmission belt 7, so that the first gear shaft 5 and the second gear shaft 6 on both sides of the rotating shaft 2 can rotate in opposite directions, thereby ensuring the orderly entry or withdrawal of the wiring harness 3.

[0054] Optionally, the first gear column 8 is bonded to the first gear shaft 5, and the third gear column 10 is bonded to the second gear shaft 6. This makes the connection between the first gear column 8 and the first gear shaft 5 relatively simple, and also makes the connection between the third gear column 10 and the second gear shaft 6 relatively simple.

[0055] Optionally, the anti-explosion wire winding mechanism further includes a first gear column 8 shaft and a second gear column 9 shaft;

[0056] The second gear column 9 is movably sleeved on the outer side of the axis of the first gear column 8 ; the fourth gear column 11 is movably sleeved on the outer side of the axis of the second gear column 9 .

[0057] In the above embodiment, this helps to ensure the installation stability of the second tooth column 9 and the fourth tooth column 11 .

[0058] Optionally, the explosion-proof wire winding mechanism further includes a winding bin 17; the interior of the winding bin 17 is hollow to form a receiving chamber;

[0059] The winding column 1, the central gear 4, the first gear shaft 5, the first gear 51, the second gear shaft 6, the second gear 61, the first gear column 8, the second gear column 9, the third gear column 10 and the fourth gear column 11 are all located in the accommodating cavity. The second end of the rotating shaft 2 can be rotatably connected to the winding bin 17 through a bearing.

[0061] Optionally, the anti-explosion wire winding mechanism further includes a first positioning pin 18 and a second positioning pin 19, wherein the first positioning pin 18 is disposed at the bottom of the first gear shaft 5, and the second positioning pin 19 is disposed at the bottom of the second gear shaft 6.

This helps to ensure the stability of the rotation process of the first gear shaft 5 and the second gear shaft 6.

[0063] In a specific implementation, the working principle of the anti-explosion wire winding mechanism is as follows:

[0064] Step 1: The device is powered on and the motor 12 starts to rotate.

[0065] Step 2: The motor 12 rotates and drives the driving gear 13 to rotate, which in turn drives the driven gear 14 to rotate, and the rotating shaft 2 rotates. At this time, the winding rod 1 starts to wind / release the line.

[0066] Step 3: The central gear 4 on the top of the rotating shaft 2 also starts to rotate and drives the first gear shaft 5 and the second gear shaft 6 on both sides to start rotating.

[0067] Step 4: Since the first gear shaft 5 and the second gear shaft 6 cooperate with the central gear 4 in different ways, the first gear shaft 5 and the second gear shaft 6 rotate in opposite directions. Since the first end of the harness 3 is stuck between the first groove 81 of the first tooth column 8 and the second groove 91 of the second tooth column 9, and the second end of the harness 3 is stuck between the third groove 101 of the third tooth column 10 and the fourth groove 111 of the fourth tooth column 11, the harness 3 begins to enter and withdraw in an orderly manner under the effect of rotation and extrusion. Because the harness 3 is stuck in the groove and the activity space is limited, it prevents the harness 3 from being entangled, knotted, or blown due to excessive up and down movement.

[0068] According to the second aspect of the present invention, see Figure 1, provides a wearable device, which adopts the anti-explosion wire winding mechanism as described in the first aspect, including the anti-explosion wire winding mechanism and the telescopic mechanism:

[0069] The driving mode of the telescopic mechanism is rope drive, and the wire harness 3 of the telescopic mechanism is fixedly connected with the wire harness 3 of the anti-explosion wire winding mechanism. That is, the telescopic mechanism is telescoped and stretched by winding the wire of the winding mechanism.

[0070] In the above embodiment, the anti-explosion wire winding mechanism can be applied to the rehabilitation auxiliary wearable device industry, and can solve the problems of wire explosion and knotting in the winding process of the existing winding device. Moreover, the application of the winding mechanism in the field of small rehabilitation auxiliary wearable devices provides a new automatic wearing solution for this field, which can enhance the user experience.

[0071] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
