[0055] Please also refer to Figures 1 to 13 This utility model provides a preferred embodiment of a data cable storage device that allows for smooth data cable retraction.

[0056] In some embodiments, please refer to Figures 1 to 6This utility model provides a data cable storage device with smooth data cable retraction, comprising: a lower terminal block assembly 1, an upper cover 2, a turntable 4, an upper terminal block assembly 3, a rotating shaft 5, a spring 6, a data cable 7, and a swing arm assembly 8; the data cable 7 is disposed on the turntable 4 and electrically connected to the upper terminal block assembly 3; the upper terminal block assembly 3 is disposed on the turntable 4 and connected to the lower terminal block assembly 1; the rotating shaft 5 is disposed on the upper cover 2, and the turntable 4 is disposed between the upper cover 2 and the lower terminal block assembly 1; one end of the spring 6 is disposed on the turntable 4, and the other end of the spring 6 is sleeved on the rotating shaft 5; the swing arm assembly 8 is disposed on the lower terminal block assembly 1 and is used to cooperate with the turntable 4 to lock the turntable 4; the rotating shaft 5 is provided with a first step structure 51 and a second step structure 52, the turntable 4 is sleeved on the first step structure 51, and the upper cover 2 is disposed between the top of the rotating shaft 5 and the second step structure 52.

[0057] Specifically, the lower terminal block assembly 1 is snapped together with the upper cover 2. The data cable 7 is wound around the turntable 4, which is mounted on the rotating shaft 5. The two ends of the spring 6 are connected to the turntable 4 and the rotating shaft 5 respectively, and the upper terminal block assembly 3 is mounted on the turntable 4. The upper terminal block assembly 3 is connected to the lower terminal block assembly 1, and one end of the data cable 7 is electrically connected to the upper terminal block assembly 3, thus enabling the connection between the data cable 7 and the lower terminal block assembly 1. The data cable 7 can be a TYPE-C data cable, with the other end being a male connector. The lower terminal block assembly 1 can be connected to a charger, computer, tablet, etc. Taking a charger as an example, when the data cable storage device is used as a charging device, the lower terminal block assembly 1 is connected to the charger to achieve the charging function.

[0058] When the data cable 7 is pulled, the turntable 4 rotates, the upper terminal block assembly 3 rotates with the turntable 4, the spring 6 stores power so that the turntable 4 returns to its initial position, and the swing arm assembly 8 can cooperate with the turntable 4 to lock the turntable 4, so that the data cable 7 can be kept in a state of being pulled out to a certain length for user use.

[0059] The rotating shaft 5 is provided with a first step structure 51 and a second step structure 52. The turntable 4 is sleeved on the first step structure 51. The upper cover 2 is located between the top of the rotating shaft 5 and the second step structure 52. The first step structure 51 has a limiting function for the turntable 4, and the second step structure 52 has an isolating function for the upper cover 2, so that there is a gap between the upper cover 2 and the turntable 4. In this way, the turntable 4 always maintains a certain gap with the upper cover 2 during rotation, thereby avoiding contact between the turntable 4 and the upper cover 2, which can improve the smoothness of the data cable 7 when it is pulled out and avoid the discomfort caused by jamming.

[0060] In some embodiments, the rotating shaft 5 is provided with a slot 53, and the mainspring 6 passes through the slot 53.

[0061] In this embodiment, the mainspring 6 first passes through the slot 53 before connecting to the rotating shaft 5, which can enhance the connection stability between the mainspring 6 and the rotating shaft 5.

[0062] In some embodiments, the rotating shaft 5 is a metal rotating shaft, and the upper cover 2 is formed on the rotating shaft 5 by injection molding.

[0063] In this embodiment, the pivot 5 is made of metal material and can be injection molded onto the upper cover 2. This increases the strength of the pivot 5 and extends the service life of the data cable storage device.

[0064] In some embodiments, please refer to Figure 2 and Figure 3 The lower terminal block assembly includes a lower cover 11 and a lower terminal block 12; the lower cover 11 is injection molded onto the lower terminal block 12; the upper terminal assembly includes a plastic base 31 and an upper terminal block 32; the plastic base 31 is injection molded onto the upper terminal block 32.

[0065] Specifically, the upper terminal block 32 is disposed on the plastic base 31, wherein the plastic base 31 is injection molded onto the upper terminal block 32, realizing the function of circuit board + connector. The lower terminal block 12 is disposed in the lower cover 11, wherein the lower cover 11 is injection molded onto the lower terminal block 12, which can also realize the function of circuit board + connector. Compared with the existing method of using circuit boards, it has lower cost and higher integration. The terminals of the upper terminal block 32 and the lower terminal block 12 are electrically connected, and one end of the data line 7 is electrically connected to the upper terminal block 32, thus realizing the connection between the data line 7 and the lower terminal block 12.

[0066] In some embodiments, please refer to Figure 7 and Figure 8The turntable 4 is provided with a plurality of locking structures 41, which are spaced along the edge of the lower terminal block 12 on the turntable 4, and a receiving groove 42 is formed between two adjacent locking structures 41.

[0067] Furthermore, the swing arm assembly 8 includes: a retaining spring 81, an upper swing arm 82, and a lower swing arm 83; the retaining spring 81 is engaged with the lower cover 11; the upper swing arm 82 is rotatably connected to the lower cover 11 and abuts against the retaining spring 81; the lower swing arm 83 is rotatably connected to the lower cover 11 and is located between the upper swing arm 82 and the lower cover 11.

[0068] It is important to understand that during the molding process of the upper terminal block 32, i.e., when the upper terminal block 32 and the plastic base 31 are injection molded, and when the lower terminal block 12 and the lower cover 11 are injection molded, both are achieved using an injection molding machine. Specifically, please refer to... Figure 9 and Figure 10 First, the upper terminal block 32 and the lower terminal block 32 need to be obtained through a stamping process. The terminal blocks obtained after stamping are generally connected by a strip 9, which facilitates subsequent automatic production on the injection molding machine. For example, the lower terminal block 12 can be automatically fed to the injection molding machine through the strip 9 to achieve automated production. However, for the lower terminal block 12, because the plastic part of the lower terminal block 12 needs to cooperate with the swing arm assembly 8 to complete the locking function of the turntable 4, the outer diameter of the plastic part will be larger than the outer diameter of the lower terminal block 12. That is, part of the plastic part will protrude from the edge of the lower terminal block 12. In this way, if the lower terminal block 12 is connected by the strip 9 for injection molding, two notches will be added to the plastic part (the notches left after the strip 9 is removed). Ultimately, this will affect the locking assembly when pulling data, such as the pulling line not being smooth enough.

[0069] In this embodiment, the locking function is achieved by transferring the structure that cooperates with the swing arm assembly 8 to the turntable 4. Specifically, the locking function is achieved by replacing the plastic part of the original lower terminal block 12 with the locking structure 41 on the turntable 4. Specifically, the lower cover 11 has two slots 53, and the two ends of the retaining spring 81 are engaged in the slots 53 of the lower cover 11. The upper swing arm 82 is mounted on the first mounting post 111 of the lower cover 11, and the lower swing arm 83 is mounted on the second mounting post 112 of the lower cover 11. Both the upper swing arm 82 and the lower swing arm 83 are rotatably connected to the lower cover 11. When the data cable 7 is pulled, the data cable 7 drives the turntable 4 to rotate, the turntable 4 drives the upper swing arm 82 to swing, and the upper swing arm 82 drives the lower swing arm 83 to rotate. When locking the turntable 4, the upper swing arm 82 abuts against the lower swing arm 83 and the locking structure 41 respectively, causing the turntable 4 to stop rotating. In this way, the plastic parts of the lower terminal block 12 do not need to extend beyond the edge of the lower terminal block 12, so that the lower terminal block 12 can be connected by the material strip 9 to realize automated feeding, which greatly improves production efficiency and reduces production costs.

[0070] In some embodiments, please refer to Figure 7 and Figure 8 The upper swing arm 82 includes a first locking block 821, a second locking block 822, and an abutment portion 823; the first locking block 821 and the second locking block 822 are disposed on both sides of the upper swing arm 82; the abutment portion 823 is located at the bottom of the upper swing arm 82; the lower swing arm 83 includes a third locking block 831, which is disposed at intervals along the edge of the lower swing arm 83 on the side of the lower swing arm 83 near the upper swing arm 82.

[0071] In this embodiment, the size of the abutment portion 823 of the upper swing arm 82 is adapted to the size of the receiving groove 42. In the initial state, the abutment portion 823 is located within the receiving groove 42. When the data cable 7 is pulled, the turntable 4 rotates, the abutment portion 823 disengages from the receiving groove 42 and slides on the locking structure 41, the upper swing arm 82 swings, and the second locking block 822 of the upper swing arm 82 abuts against the third locking block 831 of the lower swing arm 83, causing the lower swing arm 83 to swing with the upper swing arm 82. When the data cable 7 is stopped being pulled, the abutment portion 823 abuts against the locking structure 41, the first locking block 821 abuts against the third locking block 831, causing the turntable 4 to stop rotating, thereby achieving the anti-reverse function, and the data cable 7 stops moving.

[0072] In some embodiments, please refer to Figure 7The third locking block 831 is provided with an abutment groove 832. When the turntable 4 is locked, the first locking block 821 abuts against the abutment groove 832.

[0073] In this embodiment, when the turntable 4 is in the locked state, the abutting part 823 of the upper swing arm 82 abuts against the locking structure 41, and the first locking block 821 of the upper swing arm 82 engages with the abutting groove 832 on the third locking block 831 of the lower swing arm 83 to lock the turntable 4, and the data line 7 is prevented from retracting.

[0074] In some embodiments, please refer to Figure 12 and Figure 13 The plastic base 31 has a partition structure 311 on its back, and the terminals of the upper terminal block 32 are located between the partition structures 311; the turntable 4 has a clearance hole 43 at the position corresponding to the partition structure 311 for the data cable 7 to pass through.

[0075] In this embodiment, when installing the upper terminal block 32, the data cable 7 is first soldered onto the upper terminal block 32. To prevent short circuits between the terminals of the upper terminal block 32 during soldering, a partition structure 311 is provided on the back of the plastic base 31. During soldering, the solder joints are isolated by the partition structure 311, thus preventing the solder from connecting adjacent terminals together and causing a short circuit. After soldering the data cable 7 onto the upper terminal block 32, the plastic base 31 with the upper terminal block 32 is installed on the turntable 4. The data cable 7 can pass through the clearance hole 43 on the turntable 4 and then be wound around the turntable 4.

[0076] In some embodiments, please refer to Figure 12 The turntable 4 includes: a first mounting part 44, a second mounting part 45, a third mounting part 46, and a fourth mounting part 47; the spring 6 is housed in the first mounting part 44, and one end of the spring 6 is connected to the third mounting part 46; the first mounting part 44 is provided with a first notch, and the second mounting part 45 is provided with a second notch, the first notch and the second notch forming a fixing groove 48; the end of the data cable 7 connected to the turntable 4 is provided with a latching part 71, the latching part 71 engaging with the fixing groove 48; the fourth mounting part 47 is located on one side of the third mounting part 46 and is spaced apart from the second mounting part 45.

[0077] In this embodiment, the first mounting part 44 has an arc-shaped structure and is arranged around the rotating shaft 5. The spring 6 is located within the space surrounded by the first mounting part 44, and one end of the spring 6 is fixedly connected to the third mounting part 46. The first mounting part 44 and the second mounting part 45 have notches at their contact points with the data cable 7, forming a fixing groove 48. The data cable 7 has a snap-fit ​​part 71 that matches the size of the fixing groove 48. The data cable 7 is clamped between the first mounting part 44 and the second mounting part 45 through the snap-fit ​​part 71, achieving a fixed connection between the data cable 7 and the turntable 4. This eliminates the need for glue bonding and prevents the data cable 7 from loosening due to glue failure. To provide space for soldering the data cable 7, the position between the fourth mounting part 47 and the second mounting part 45 is hollowed out to form the clearance hole 43. The fourth mounting part 47 abuts against the data cable 7, providing support for the data cable 7.

[0078] In some embodiments, the present invention also provides an electronic device including a data cable storage device with smooth data cable retraction as described above. Specific details are provided for the data cable storage device with smooth data cable retraction, and will not be repeated here.

[0079] In summary, the data cable storage device and electronic device with smooth data cable pull-out provided by this utility model have the following beneficial effects:

[0080] The rotating shaft is provided with a stepped structure, which allows the turntable to maintain a certain gap with the top cover during rotation, thereby preventing the turntable from contacting the top cover and improving the smoothness of the data cable when pulling it out, thus avoiding the discomfort caused by jamming.

[0081] By setting the locking structure on the turntable, that is, transferring the locking structure from the plastic base to the turntable, the plastic base is injection molded into the upper terminal block. The upper terminal blocks can be connected together by the material strip to achieve automated production. Compared with the traditional manual operation to complete the injection molding process of a single upper terminal block, the production efficiency is improved.

[0082] The partition structure is set on the back of the plastic base. During welding, the solder joints are isolated by the partition structure, which can prevent the solder from connecting two adjacent terminals together and causing a short circuit.

[0083] The hinge is made of metal, and the top cover is injection molded onto the hinge. This increases the strength of the hinge, thereby extending the service life of the data cable storage device.

[0084] The data cable is clamped between the first mounting part and the second mounting part through its buckle, realizing the fixed connection between the data cable and the turntable. This eliminates the need for glue, preventing the data cable from loosening due to glue failure, and can withstand greater pressure.

[0085] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
