DETAILED DESCRIPTION

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0035] like Figures 1 to 15 As shown, the embodiment of the present invention is a retractable charging cable that is easy to use, comprising a housing 1, an unlocking member 2 provided in the housing 1, a storage mechanism provided in the housing 1, and a data cable installed in the storage mechanism; the storage mechanism can rotate and store the data cable, and the principle of a clockwork spring is adopted therein to rewind and unwind the data cable, which belongs to the prior art and will not be described in detail here; the housing 1 is provided with a storage cavity for accommodating a charging head 3 of the data cable and an entrance and exit communicated with the storage cavity; the data cable extends out of the housing 1 through the entrance and exit; the charging head 3 is provided with a first locking groove 31; a first locking member 4 for lockingly cooperating with the first locking groove 31 is hinged in the housing 1; when the first locking member 4 is lockedly cooperating with the first locking groove 31, the charging head 3 remains accommodated in the storage cavity;

[0036] The first locking member 4 is in contact with the unlocking member 2, so that the first locking member 4 can be operated by the unlocking member 2 when in use, so that the first locking member 4 and the first locking groove 31 are unlocked, and the charging head 3 is in an unlocked state; the unlocking member 2 can be set as a key structure, so that a pressing operation can be performed when in use; the unlocking member 2 is rotatably provided with a rotating member 21 exposed outside the shell 1, and the inner wall of the rotating member 21 is provided with a rotating driving structure; the rotating member 21 can be set as a knob structure, so that a twisting operation can be performed when in use; the user can press the unlocking member 2 through the rotating member 21;

[0037] A push seat 51 and a slider 52 located on the side of the push seat 51 facing away from the entrance and exit are slidably provided at one end of the storage chamber away from the entrance and exit; a first spring 53 is connected between the slider 52 and the inner wall of the shell 1, so that when the charging head 3 is in an unlocked state, the first spring 53 applies elastic force to the slider 52, and the charging head 3 is pushed out of the storage chamber through the push seat 51 to extend out of the entrance and exit, so that the user can access the data cable; the slider 52 is provided with a second locking groove 521; the inner wall of the shell 1 is elastically provided with a second locking member 6 for locking cooperation with the second locking groove 521, and the push seat 51 can release the locking cooperation between the second locking member 6 and the second locking groove 521; a transmission assembly is provided in the shell 1, one end of the transmission assembly is transmission-connected with the slider 52 to drive the slider 52 to slide relative to the push seat 51 and compress the first spring 53, and the other end of the transmission assembly is transmission-connected with the rotation drive structure;

[0038] When the slider 52 compresses the first spring 53 and slides to the position where the second locking groove 521 corresponds to the second locking member 6, the slider 52 disengages from the push seat 51, and the second locking member 6 locks with the second locking groove 521, thereby locking the slider 52, so that the first spring 53 remains in a compressed state. At this time, the first spring 53 maintains an elastic energy storage state, so that the charging head 3 is automatically retracted into the storage chamber through the entrance and exit under the winding force of the storage mechanism, and the first locking member 4 is locked with the first locking groove 31 again; at the same time, when the charging head 3 is retracted into the storage chamber, the charging head 3 pushes the push seat 51 to slide toward the slider 52, and the push seat 51 releases the locking cooperation with the second locking groove 521 during the sliding process.

[0039] Specifically, initially, Figure 2 As shown, the first locking member 4 is locked with the first locking groove 31, so that the charging head 3 remains accommodated in the storage cavity, the second locking member 6 and the first locking groove 31 are in an unlocked state, and the first spring 53 is in a compressed state; when the data cable needs to be used, the user presses the unlocking member 2 through the rotating member 21 to release the locking cooperation between the first locking member 4 and the first locking groove 31. At this time, the charging head 3 is in an unlocked state, and the elastic potential energy of the first spring 53 is released, pushing the slider 52 to slide, and then pushing the push seat 51 to slide, and the push seat 51 pushes the charging head 3 to extend outward, so that the user can use the data cable. Figure 6 As shown;

[0040] When storage is required, by screwing the rotating member 21, the rotating member drives the slider 52 to compress the first spring 53 and slide away from the push seat 51 through the rotation drive structure and the transmission assembly until the second locking member 6 is locked with the second locking groove 521, the slider 52 is locked by the second locking member 6, and the first spring 53 maintains the elastic energy storage state. At this time, the push seat 51 is not subjected to the elastic force of the first spring 53. Figure 8As shown, when the storage mechanism reels in the data cable, the charging head 3 can easily push the push seat 51 to slide and be stored in the storage cavity until the first locking member 4 is locked with the first locking groove 31 again, and at the same time, the push seat 51 releases the locking cooperation between the second locking member 6 and the second locking groove 521. At this time, the slider 52 is in an unlocked state, and the push seat 51 is again subjected to the elastic force of the first spring 53 to facilitate the next pushing operation of the charging head 3.

[0041] In this embodiment, the first locking member 4 is locked with the first locking groove 31, and the rotation drive structure of the rotating member 21 cooperates with the transmission assembly, so that the slider 52 can compress the first spring 53, and the second locking member 6 is locked with the second locking groove 521 to keep the first spring 53 in an elastic energy storage state, thereby avoiding the problem of the charging head 3 not being able to be fully retracted due to elastic energy storage, thereby achieving smooth storage of the charging head 3, without the need for manual pushing to retract the charging head 3, and making the structure more convenient and reliable to use.

[0042] like Figure 4 , Figure 7 , Figure 8 and Fig.11 As shown, the present embodiment is an easy-to-use retractable charger. In some embodiments, the transmission assembly includes a first transmission rod 71 and a second transmission rod 72 rotatably arranged in the shell 1, and a third transmission rod 73 rotatably arranged on the unlocking member 2; one end of the first transmission rod 71 is transmission-connected with one end of the second transmission rod 72, and the other end of the first transmission rod 71 moves through the push seat 51 and the slider 52 in sequence; the outer wall of the first transmission rod 71 is provided with a first spiral groove 711, and the inner wall of the slider 52 is provided with a first pin shaft 522 that is movably embedded in the first spiral groove 711; the other end of the second transmission rod 72 is transmission-connected with one end of the third transmission rod 73, and the other end of the third transmission rod 73 is transmission-connected with the rotating drive structure. Specifically, when the rotating member 21 is screwed, the rotation driving structure of the rotating member 21 causes the third transmission rod 73 to rotate, the third transmission rod 73 drives the second transmission rod 72 to rotate, the second transmission rod 72 drives the first transmission rod 71 to rotate, the first transmission rod 71 cooperates with the first pin 522 through the first spiral groove 711, and drives the slider 52 to slide away from the push seat 51, thereby compressing the first spring 53 until the second locking member 6 is locked and matched with the second locking groove 521;

[0043] When the first spring 53 pushes the charging head 3 outward, the slider 52 cooperates with the first pin 522 through the first spiral groove 711 to drive the first transmission rod 71 to rotate. Through the transmission of the second transmission rod 72 and the third transmission rod 73, the rotating part 21 is reset for the next screwing operation.

[0044] like Fig.11As shown, the present embodiment is an easy-to-use retractable charger. Furthermore, one end of the first transmission rod 71 and one end of the second transmission rod 72 are both provided with a bevel gear 74, and the bevel gear 74 of the first transmission rod 71 is meshed with the bevel gear 74 of the second transmission rod 72; the other end of the second transmission rod 72 and one end of the third transmission rod 73 are both provided with a transmission wheel 75, and a transmission belt 76 is wound around the transmission wheel 75 of the first transmission rod 71 and the transmission wheel 75 of the third transmission rod 73; in this way, through the above-mentioned arrangement, the linkage between the first transmission rod 71 and the second transmission rod 72, and the linkage between the second transmission rod 72 and the third transmission rod 73 are realized.

[0045] like Figure 4 , Figure 7 , Figure 8 , Fig.11 and Fig.12 As shown, the present embodiment is an easy-to-use retractable charger. In some embodiments, a gear 77 is provided at the other end of the third transmission rod 73, and the rotation driving structure is a gear ring 22. The gear 77 of the third transmission rod 73 meshes with the gear ring 22. In this way, when the rotating member 21 rotates, the gear ring 22 drives the third transmission rod 73 to rotate through the gear 77. The third transmission rod 73 drives the second transmission rod 72 to rotate through the transmission wheel 75 and the transmission belt 76. The second transmission rod 72 drives the first transmission rod 71 to rotate through the bevel gear 74. The first transmission rod 71 drives the slider 52 to slide away from the push seat 51 through the first spiral groove 711 and the first pin shaft 522, thereby compressing the first spring 53. In this way, the rotational motion of the rotating member 21 is converted into a linear sliding of the slider 52, so that the charging head 3 can be smoothly retracted.

[0046] like Figure 5 and Fig.10As shown, the easy-to-use retractable charger of this embodiment, in some embodiments, the second locking member 6 is provided with an inclined surface 61, an extrusion plane 62 and a concave surface 63 on the side facing the slider 52; a locking boss 64 is convexly provided on the concave surface 63; a second spring 65 is connected between the side of the second locking member 6 facing away from the slider 52 and the inner wall of the shell 1. Specifically, at the beginning, the charging head 3 is accommodated in the storage cavity, and the side surface of the push seat 51 contacts the extrusion plane 62, so that the second spring 65 is compressed. At this time, the locking boss 64 is relative to the second locking groove 521. Since the second locking member 6 is squeezed by the push seat 51, the locking boss 64 cannot be stuck in the second locking groove 521 under the elastic force of the second spring 65, that is, the slider 52 is in the unlocked state at this time. After the first locking member 4 and the first locking groove 31 are released from the locking cooperation, the first spring 53 pushes the slider 52 and the push seat 51 to slide, and the charging head 3 is pushed out of the storage cavity. During this process, the side surface of the slider 52 will slide to contact the extrusion plane 62 of the second locking member 6, so that the second locking member 6 maintains a retreat state, thereby staggering the locking boss 64 and the second locking groove 521, until the slider 52 is completely out of contact with the second locking member 6, and the second spring 65 pushes the second locking member 6 to pop out;

[0047] When the user screws the rotating member 21, the first transmission member drives the slider 52 to compress the first spring 53 and slide. The slider 52 will first contact the inclined surface 61 of the second locking member 6, thereby generating an extrusion force on the second locking member 6, and the second spring 65 is compressed, causing the second locking member 6 to retract until the slider 52 transitions from contacting the inclined surface 61 to contacting the extrusion plane 62, so that the second locking member 6 remains in a retracted state. After the slider 52 is out of contact with the extrusion plane 62, the slider 52 is opposite to the inner concave surface 63, that is, the locking boss 64 is aligned with the second locking groove 521. At this time, the second locking member 6 is not squeezed by the slider 52, and the second spring 65 recovers its deformation, pushing the slider 52 to extend again, so that the locking boss 64 is stuck in the second locking groove 521, locking the slider 52. Figure 8 As shown;

[0048] When the charging head 3 is retracted into the storage cavity and pushes the push seat 51 to slide, the push seat 51 contacts the inclined surface 61 of the second locking member 6, thereby generating a squeezing force on the second locking member 6, and the second spring 65 is compressed, so that the second locking member 6 retracts, so that the locking boss 64 withdraws from the second locking groove 521, thereby unlocking the slider 52. Figure 5 As shown, after the first locking member 4 is released from the locking engagement with the first locking groove 31 , the first spring 53 releases its elastic stored energy to push out the charging head 3 .

[0049] like Fig. 9 and Fig.10As shown, the retractable charger that is easy to use in this embodiment, specifically, the second locking groove 521 is a round hole, and the locking boss 64 is provided with a spherical portion. It is arranged in this way so that the locking boss 64 is easier to be inserted into the round hole, and the locking movement of the slider 52 is more reliable.

[0050] like Figure 2 As shown, the embodiment of the retractable charger is easy to use. In some embodiments, a card table 41 is provided at one end of the first locking member 4, and a third spring 42 is connected between the other end of the first locking member 4 and the inner wall of the housing 1; the third spring 42 keeps the first locking member 4 in contact with the unlocking member 2. In this embodiment, the third spring 42 is provided to ensure that the first locking member 4 can always maintain a tendency to contact the unlocking member 2, so that after the user presses the unlocking member 2, the unlocking member 2 can automatically reset, and after the charging head 3 is retracted into the receiving chamber, the card table 41 can automatically snap into the first locking groove 31 under the elastic force of the third spring 42 to achieve locking of the charging head 3.

[0051] like Figure 4 and Figure 5 As shown, the embodiment of the retractable charger is easy to use. In some embodiments, a guide shaft 511 is extended from the side of the push seat 51 facing away from the entrance, and the slider 52 is slidably sleeved on the outer wall of the guide shaft 511. In this embodiment, the guide shaft 511 is arranged on the push seat 51 to provide guidance and limit for the slider 52, so that the slider 52 can reliably compress the first spring 53, and when the first spring 53 releases the elastic stored energy, it can stably push the push seat 51 to slide and push out the charging head 3.

[0052] like Figures 1 to 4 , Figures 6 to 8 , Figures 13 to 15 As shown, the embodiment of the retractable charger is easy to use. In some embodiments, the housing 1 is hinged with an end cover 81 for blocking the entrance and exit at the position corresponding to the entrance and exit. In this embodiment, the end cover 81 is provided to block the entrance and exit through the end cover 81 to prevent foreign matter from entering the storage cavity, and the structure is safer and more reliable to use. When the charging head 3 is ejected, the charging head 3 pushes the end cover 81 to flip outward and open, thereby realizing the automatic opening operation.

[0053] like Figures 1 to 4 , Figures 6 to 8 , Figures 13 to 15As shown, the easy-to-use retractable charger of this embodiment, in some embodiments, the shell 1 is provided with a slide groove at the position corresponding to the entrance and exit, and a slide seat 82 is slidably provided in the slide groove; a hinge shaft 83 is slidably passed through one end of the slide seat 82; the end cover 81 is provided with a hinge ear 811, and the hinge ear 811 is hinged to the slide seat 82 through the hinge shaft 83; the outer wall of the hinge shaft 83 is provided with a second spiral groove 831; the inner wall of the hinge ear 811 is provided with a second pin shaft 812; the second pin shaft 812 is movably embedded in the second spiral groove 831; an elastic rope 84 is connected between the hinge ear 811 and the inner wall of the shell 1.

[0054] Specifically, when the end cover 81 is in the closed state, the end cover 81 is accommodated in the entrance and exit. Figures 1 to 3 As shown; when the charging head 3 is ejected, the charging head 3 pushes the end cover 81, causing the slide 82 to slide outward, so that the end cover 81 moves out of the exit and entrance, and the elastic rope 84 is deformed. Then, under the thrust of the charging head 3, the end cover 81 is flipped outward with the hinge shaft 83 as the fulcrum, and the elastic rope 84 is further deformed. At the same time, the hinge ear 811 rotates relative to the hinge shaft 83, and the second pin shaft 812 moves along the trajectory of the second spiral groove 831, thereby converting the rotation of the hinge ear 811 into a linear sliding of the second pin shaft 812, so that the second pin shaft 812 slides relative to the slide seat 82 along its axis until one end of the hinge shaft 83 protrudes out of the slide seat 82. At this time, the hinge shaft 83 cooperates with the side wall of the shell 1 to limit the slide seat 82 to prevent the slide seat 82 from shrinking during the flipping of the end cover 81, so as to ensure the flipping action of the end cover 81, as shown in FIG. Figures 6 to 8 As shown; until the charging head 3 is fully extended, the end cover 81 is flipped inwards at a certain angle under the action of the elastic rope 84, and at this time the end cover 81 is not completely flipped;

[0055] When the charging head 3 is retracted, during the process of the charging head 3 being retracted, the charging head 3 squeezes the end cover 81 through the inclined surface thereon, causing the end cover 81 to flip outward to avoid it, so that the charging head 3 can be retracted into the receiving chamber through the entrance and exit. After the charging head 3 is completely retracted into the receiving chamber, the end cover 81 flips inward under the action of the elastic rope 84 until the end cover 81 is completely flipped. At this time, the second pin shaft 812 cooperates with the second spiral groove 831 to retract the hinge shaft 83, releasing the limit on the slide seat 82, and then the elastic rope 84 pulls the slide seat 82 inward to retract it, so that the end cover 81 is accommodated in the entrance and exit, thereby completely closing the end cover 81.

[0056] In this embodiment, a hinge shaft 83 is arranged to extend outward when the end cover 81 is flipped outward, thereby limiting the slide seat 82 to prevent the slide seat 82 from being unable to be fully retracted due to the end cover 81 not being fully flipped inward when closing, thereby ensuring smooth retraction of the end cover 81.

[0057] like Figures 13 to 15As shown, the retractable charger is easy to use in this embodiment. Preferably, a square portion is provided at one end of the hinge shaft 83. The square portion is provided to limit the rotational freedom of the hinge shaft 83 so that the hinge shaft 83 can only slide along its axis to ensure reliable flipping of the end cover 81.

[0058] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
