Description

Technical Field

[0001] This utility model relates to the field of retractable data cables, and in particular to a retractable data cable with decompression sound generation function. Background Technology

[0002] With the development of electronic devices, retractable data cables have emerged, greatly improving their storage and aesthetics. Existing retractable data cables generally have two states: unfolded and retracted.

[0003] However, existing retractable data cables, such as the one described in Chinese patent 202420261100.9, only produce the ratchet sound during use, which is relatively monotonous. In addition, during actual use, the retractable cable is prone to problems such as the spring force causing the cable to retract too quickly when it is being wound up, which affects the user experience.

[0004] There are several problems with the retractable cable winding too fast: 1. It can cause the end of the retractable cable to easily separate from the PCB board due to force; 2. The friction between the outer protective layer and the shell of the retractable cable is large, which can easily lead to wear of the skin. Summary of the Invention

[0005] The main purpose of this invention is to propose a retractable data cable with decompression sound generation, which aims to improve the existing retractable data cable structure. It can not only emit a crisp sound to relieve pressure, but also has a modular design for easy installation and can also serve as a damper when rewinding, thus improving the user experience.

[0006] To achieve the above objectives, this utility model proposes a retractable data cable with decompression sound generation capability, comprising:

[0007] The housing has a receiving cavity;

[0008] A turntable, which is pivotally mounted in a receiving cavity, is provided with a partition that divides the turntable into an inner cavity and an outer cavity;

[0009] A torsion spring is provided in the inner cavity, with one end connected to the turntable and the other end connected to the housing. The torsion spring is used to apply a spring force to the turntable to wind up the data cable.

[0010] A sound-generating device, which is detachably installed on the upper part of the inner cavity of the turntable, includes a base and a swing arm that is oscillatingly disposed on the base;

[0011] The housing has a concave-convex part extending toward the inner cavity in the middle, and the swing arm can swing between a position that is in contact with the outer wall of the concave-convex part and a position that is away from it.

[0012] In practical design, the sound-generating device is modularly arranged and placed on a turntable, allowing it to rotate with the turntable. As the turntable rotates, the end of the swing arm abuts against the concave and convex parts, thus producing sound.

[0013] When the turntable needs to retract the data cable, the contact between the swing arm and the concave and convex parts acts as a damping mechanism. At the same time, because the turntable retracts under the elastic force of the torsion spring, the sound interval is uniform when the end of the swing arm contacts the concave and convex parts, and the sound is like the sound of a woodpecker, thus improving the user experience of the retractable data cable.

[0028] like Figures 1 to 4 As shown, a retractable data cable with decompression sound emission function includes:

[0029] Housing 1, wherein housing 1 is provided with a receiving cavity 10;

[0030] Turntable 2 is pivotally mounted in receiving cavity 10. Turntable 2 is provided with partition 20, which is divided into inner cavity 21 and outer cavity 22.

[0031] Torsion spring 23, which is located in the inner cavity 21 and has one end connected to the turntable 2 and the other end connected to the housing 1, is used to apply a spring force to the turntable 2 to wind up the data cable;

[0032] The sound-generating device 3 is detachably installed on the upper part of the inner cavity 21 of the turntable 2. The sound-generating device 3 includes a base 31 and a swing arm 4 that is oscillatingly disposed on the base 31.

[0033] The housing 1 has a concave-convex part 5 extending toward the inner cavity 21 in the middle part, and the swing arm 4 can swing between a position that is in contact with the outer wall of the concave-convex part 5 and a position that is away from it.

[0034] In the actual design, the sound-generating device 3 is modularly arranged and placed on the turntable 2, so that the sound-generating device 3 rotates with the turntable 2. When the turntable 2 rotates, the end of the swing arm 4 abuts against the concave and convex parts, thereby realizing sound generation.

[0035] When the turntable 2 needs to rewind the data cable, the contact between the swing arm 4 and the concave and convex parts can act as a damping effect. At the same time, because the turntable 2 is rewound by the elastic force of the torsion spring 23, when the end of the swing arm 4 contacts the concave and convex parts, the sound interval is uniform, and the sound is like the sound of a woodpecker, thus improving the user experience of the retractable data cable.

[0036] Specifically, the upper wall of the base 31 is provided with a groove 32, and the middle part of the swing arm 4 is pivotally mounted in the groove 32.

[0037] In this embodiment of the utility model, the base 31 is provided with a rotating shaft 33 in the middle, and the swing arm 4 is provided with a shaft hole that cooperates with the rotating shaft 33 in the middle.

[0038] Specifically, a top spring is provided between the rear end of the swing arm 4 and the base 31, and the top spring is used to apply an elastic force to the end of the swing arm 4 to swing toward the concave and convex parts.

[0039] In this embodiment of the utility model, the front part of the swing arm 4 is provided with an impact part 41 extending toward the axis, and the front end of the swing arm 4 is provided with a stop part 42. The side wall of the stop part 42 abuts against the wall surface of the base 31. In actual design, the swing arm 4 is limited and impacted by the cooperation of the impact part 41 and the stop part 42.

[0040] Therefore, in the actual imitation design, it resembles a woodpecker's beak, changing the existing shrapnel design to make it more ingenious.

[0041] Specifically, the two sides of the impact part 41 are symmetrically arranged inclined surfaces with an arc transition.

[0042] The ends of the concave and convex parts are arc-shaped transitions. The use of arc-shaped transition slopes can achieve the predetermined impact effect and provide the predetermined resistance when passing through.

[0043] In this embodiment of the utility model, the base 31 is provided with a limiting part 43, which abuts against the stop part 42, thereby limiting the swing stroke.

[0044] Specifically, the concave and convex portion 5 extends downward to form a main shaft 6, and the turntable 2 and the base 31 are provided with through holes for the main shaft 6 to pass through, thereby realizing the relative rotation of the turntable 2.

[0045] In this embodiment of the utility model, the base 31 is located in the upper section of the through hole as a stepped groove 60. The concave and convex parts extend into the stepped groove 60 and abut against the impact part 41. The staggered design is adopted, thereby achieving the minimum thickness design.

[0046] Specifically, the base 31 is fixed to the upper part of the inner cavity 21 by a buckle, screw or glue, wherein the upper part of the inner cavity is provided with a slot, which can realize the installation limit of the torsion spring 23 and also facilitate installation.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
