[0030] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0031] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings. Figure 1 and Figure 3As shown, the improved cable telescopic structure includes a housing 100. An adapter plate 200, rotatable within the housing 100, is disposed within the housing 100. A spring 210 and a data cable 220 are disposed on one side of the adapter plate 200. The spring 210 is fixed to one side of a connecting plate 400. One end of the data cable 220 is connected to the spring 210, and the other end extends from the housing 100. A circuit board 300 and a connecting plate 400 are disposed on the side of the adapter plate 200 away from the spring 210. The circuit board 300 and the data cable... The materials 220 are electrically connected. The circuit board 300 is fixed on the adapter plate 200 and rotates synchronously with the adapter plate 200. The connecting plate 400 is fixed inside the housing 100 and forms a surface contact with the circuit board 300. A swing member 500 is provided between the adapter plate 200 and the housing 100. A receiving groove 510 is provided inside the swing member 500. A limiting structure is provided inside the receiving groove 510. When the adapter plate 200 continues to rotate inside the housing 100, the limiting structure can limit the swing amplitude of the swing member 500.

[0032] In the working state of this embodiment, the data cable 220 is coiled around the adapter plate 200, with one end connected to the spring 210 and the other end extending from the housing 100. Therefore, when the user pulls the data cable 220 outward, it overcomes the tension of the spring 210 and simultaneously drives the spring 210 to rotate, thereby causing the adapter plate 200 to rotate. Since a circuit board 300 electrically connected to the data cable 220 is provided on its other side, and when the circuit board 300 rotates synchronously, a rotational contact is formed between the circuit board 300 and the connecting plate 400, therefore, when the data cable 220 is stretched inside the housing 100, according to... This ensures electrical contact between the data cable 220 and the connecting plate 400, and also causes the swinging member 500 to swing between the adapter plate 200 and the housing 100. When the user releases the cable, the data cable 220 retracts into the housing 100 under the action of the spring 210, which causes the adapter plate 200 to rotate in the opposite direction. At the same time, it also causes the swinging member 500 to swing in the opposite direction between the adapter plate 200 and the housing 100. The limiting structure can also limit the swing amplitude of the swinging member 500 by the retraction stroke of the data cable 220, so that the data cable 220 can be stabilized at a certain retraction length.

[0033] Compared to existing technologies, this application, by providing a circuit board 300 and a connecting plate 400 in the adapter and maintaining rotational electrical contact between them, ensures that the data cable 220 can still maintain electrical contact with the connecting plate 400 when it is stretched within the housing 100. Furthermore, by using the cooperation of the swing member 500 and the limiting structure, this application limits the retraction stroke of the data cable 220, ensuring that the data cable 220 can be stably kept at a certain retraction length, thus facilitating consumer use.

[0034] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 2 As shown, a receiving cavity 230 is formed on one side of the adapter plate 200. The spring 210 is disposed in the receiving cavity 230 and can rotate synchronously with the adapter plate 200. The data cable 220 is coiled on the outer wall of the receiving cavity 230. A first through groove 110 is provided on the side wall of the housing 100. One end of the data cable 220 is connected to the spring 210, and the other end extends out of the housing 100 from the first through groove 110. Therefore, when the user pulls the data cable 220 outward, it will overcome the pulling force of the spring 210 and drive the spring 210 to rotate, thereby driving the adapter plate 200 to rotate.

[0035] Furthermore, based on the above embodiments, in combination with Figure 1 and Figure 2 As shown, a second through groove 231 is provided at the bottom of the receiving cavity 230. The data cable 220 is electrically connected to the circuit board 300 through the second through groove 231. Since the circuit board 300 and the connecting plate 400 form a rotational contact, the data cable 220 can still be electrically connected to the connecting plate 400 when it is stretched inside the housing 100.

[0036] Furthermore, based on the above embodiments, combined with Figure 3 and Figure 4 As shown, a first rotating shaft 520 is provided between one end of the swing member 500 and the housing 100, so that the swing member 500 can swing between the housing 100 and the adapter plate 200. A protrusion 530 is provided at the end of the receiving groove 510 away from the first rotating shaft 520. A convex ring 240 is provided on the side of the adapter plate 200 facing the housing 100. Positioning grooves 241 are provided on the convex ring 240 at preset intervals. When the adapter plate 400 rotates in the housing 100 to drive the swing member 500 to swing, the protrusion 530 can be inserted into the positioning groove 241, so that it can cooperate with the first rotating shaft 520 to correct the posture of the swing member 500 from the top and bottom.

[0037] Furthermore, based on the above embodiments, combined with Figure 3 and Figure 4 As shown, the limiting structure includes a movable member 511 and a first limiting block 512 and a second limiting block 513 located on both sides of the movable member 511. The first limiting block 512 and the second limiting block 513 protrude from the receiving groove 510. A second rotating shaft 511a is provided between the middle of the movable member 511 and the housing 100. Limiting grooves 511b are provided at both ends of the movable member 511. Figure 5 As shown, when the user pulls the data cable 220 outward, it overcomes the tension of the spring 210 and drives the spring 210 to rotate, thereby driving the adapter plate 200 to rotate, and in turn driving the swinging member 500 to swing. Due to excessive external force, the protrusion 530 disengages from the positioning groove 241. In this state, the limiting groove 511b at one end of the movable member 511 engages with the first limiting block 512, thereby limiting the swinging member 500. Figure 6 As shown, when the user releases their hand, the data cable 220 retracts into the housing 100 under the action of the spring 210, which will drive the adapter plate 200 to rotate in the opposite direction. At the same time, it will also drive the swinging member 500 to swing in the opposite direction between the adapter plate 200 and the housing 100. In this state, the limiting groove 511b at the other end of the movable member 511 is engaged in the second limiting block 513, thereby completing the limiting of the swinging member 500, so that the data cable 220 can be stabilized at a certain retracted length.

[0038] Furthermore, based on the above embodiments, combined with Figure 7 and Figure 8 As shown, a first receiving channel 514 is provided between the first limiting block 512 and the first rotating shaft 520, and a second receiving channel 515 is provided between the second limiting block 513 and the protrusion 530. The first receiving channel 514 and the second receiving channel 515 allow the movable member 511 to be inserted. Thus, based on the above embodiment, when the user continues to pull the data cable 220 outward, the movable member 511 will be inserted into the first receiving channel 514, thereby ensuring that the adapter plate 200 can continue to rotate. When the user releases his hand, the movable member 511 will be inserted into the second receiving channel 515, causing the adapter plate 200 to rotate in the opposite direction under the drive of the spring 210, thereby causing the data cable 220 to rewind around the outer wall of the receiving cavity 230 under the drive of the spring 210, thus completing the entire winding and unwinding process of the data cable 220.

[0039] Further, based on the above embodiment, a spring piece 250 is provided on the end face of the adapter plate 200. The end of the swing member 500 away from the protrusion 530 is pre-pressed on the spring piece 250. In this way, when the data cable 220 is stopped, the spring piece 250 can be driven by elastic force, and the protrusion 530 can be inserted into the positioning groove 241. In this state, the limiting groove 511b of the other end of the movable member 511 is inserted into the second limiting block 513, or the movable member 511 is driven to insert into the second receiving channel 515.

[0040] Furthermore, based on the above embodiments, combined with Figure 9 and Figure 10 As shown, the connecting plate 400 has a plurality of conductive springs 410 on the side facing the circuit board 300. The conductive springs 410 are used to maintain electrical contact with the circuit board 300 when it rotates. A plurality of fourth through slots 130 are provided on the bottom surface of the housing 100. The connecting plate 400 is provided with a connecting end 420. The connecting end 420 can extend from any of the fourth through slots 130, thereby facilitating electrical connection with other devices (such as battery compartments).

[0041] Furthermore, based on the above embodiments, such as Figure 1 As shown, an end cap 232 is provided on the receiving cavity 230 to prevent the mainspring 210 from coming out of the receiving cavity 230.

[0042] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
