Description

Technical Field

[0001] The utility model relates to the technical field of charging devices, in particular to a retractable data line device. Background Art

[0002] Since the retractable data cable can collect the wire into the shell to avoid scattering and entanglement, it is welcomed by many users. The traditional retractable data cable device generally drives the wheel core to rotate through the clockwork, and then retracts the data cable back into the shell through the cooperation of the rotating guide and positioning structure between the wheel core and the shell, such as a retractable double-pull data cable device disclosed in Chinese patent CN217427257U. When this type of data cable needs to be retracted, it is usually pulled outward first and then quickly released to make the positioning component leave the positioning area and release the positioning of the data cable, so that the data cable can be directly retracted into the shell. The main disadvantages of this structure are that, first, the guiding and positioning structure is relatively complicated, and generally multiple slide grooves and matching positioning beads or positioning columns are required; second, it is difficult to control the data cable recovery with one hand, and both hands must cooperate to pull the data cable first, which is not convenient to use.

DETAILED DESCRIPTION

[0020] In this embodiment, refer to Figure 1-Figure 5 The push-to-retract data cable device includes a housing 1, a wheel core 2, a circuit board, a spring and a data cable 7. The wheel core 2, the circuit board and the spring are installed in the housing 1. The data cable 7 is wound around the wheel core 2 and its interface extends out of the housing 1. The wheel core 2 is connected to the spring, and the wheel core 2 is driven to rotate by the elastic force of the spring. A gear 4 is arranged on the wheel core 2, and a limiting mechanism is arranged in the housing 1. The limiting mechanism is engaged with the gear 4 in a natural state, so that the gear 4 and the wheel core 2 will not rotate, and the data cable 7 will not be extended at this time; a button 3 is arranged on the housing 1, and the button 3 is connected to the limiting mechanism. By pressing the button 3, the limiting mechanism is driven to disengage from the gear 4, so that the gear 4 and the wheel core 2 are driven to rotate by the spring, so that the data cable 7 can be automatically retracted back into the housing 1. The gear 4 can adopt a ratchet structure, so that it is not necessary to press the button 3 when the data cable 7 is pulled out.

The limiting magnet 51 is fixed in a mounting groove 11 of the housing 1, and the limiting member 52 is movably mounted in the mounting groove 11; the reset magnet 54 is mounted in the limiting member 52, and the reset magnet 54 and the limiting magnet 51 have the same polarity to form a structure where like repels like. When the button 3 is released, the limiting member 52 is pushed until the limiting head 53 is clamped in the tooth groove of the gear 4 under the repulsive force of the limiting magnet 51 on the reset magnet 54.

[0023] The bottom surface of the button 3 has a pushing foot 31, and the pushing foot 31 is connected with the limiting member 52 through its inclined surface to form a structure that pushes the limiting member 52 to move toward the limiting magnet 51. When the button 3 is pressed, the inclined surface of the pushing foot 31 will push the limiting member 52 to slide toward the limiting magnet 51; a rebound magnet 32 ​​is arranged in the button 3, and the rebound magnet 32 ​​is opposite to the reset magnet 54 and has the same polarity. After releasing the button 3, the repulsive force between the reset magnet 54 and the rebound magnet 32 ​​will drive the button 3 to rebound and reset.

[0024] A buffer mechanism is also provided in the shell 1, and the buffer mechanism includes a buffer member 62 and a buffer driving component. The buffer member 62 includes a buffer head 63. The buffer driving component pushes the buffer member 62 to make the buffer head 63 contact with the teeth of the gear 4 to form a friction buffer and sound-generating structure when the gear 4 rotates. When the data cable 7 is pulled out or retracted, a rhythmic "da da da" sound will be emitted, which can produce a certain decompression effect.

[0025] The buffer driving component includes a buffer magnet 61 and an extrusion magnet 64. The buffer magnet 61 is fixed in another mounting groove 11 of the shell 1, and the buffer member 62 is movably installed in the mounting groove 11; the extrusion magnet 64 is installed in the buffer member 62, and the extrusion magnet 64 and the buffer magnet 61 have the same polarity to form a structure of like repels like, which is equivalent to pressing the buffer member 62 toward the gear 4 through the repulsive force of the buffer magnet 61 on the extrusion magnet 64, but through the set magnetic force and distance, it can be ensured that the buffer head 63 will not be stuck in the tooth groove.

[0026] It also includes a surface cover 8, which is fixed on the housing 1 to cover the limiting mechanism and the buffer mechanism in the housing 1. The button 3 is arranged on the surface cover 8 and passes through the surface cover 8 to connect with the limiting mechanism.

[0027] The gear 4 is an internal gear ring, and the limiting mechanism and the buffer mechanism are both arranged in the area surrounded by the gear 4; the buffer mechanism and the limiting mechanism are bilaterally symmetrical structures so that the force on the gear 4 is more balanced.

[0028] The driving component and the buffer driving component can also use springs, and the spring can be used to press against the limit member 52 to push the limit head 53 to engage with the gear 4, and the spring can be used to press against the buffer member 62 to push the buffer head 63 to contact the teeth of the gear 4, so that an effect similar to that of using a magnet can be achieved.
