Description

Technical Field

[0001] The present invention relates to the technical field of chargers, and particularly to a charger with a recyclable charging cable. Background Art

[0002] Existing electric vehicle chargers generally have problems such as large storage volume and easy entanglement of the charging cable. For example, the charging cable of a traditional charger is usually a whole flexible wire. When storing, it needs to be coiled repeatedly or a wire winder is used. On the one hand, manual coiling has a poor effect, and the coiled wire still occupies a relatively large volume. Moreover, long-term coiling and bending easily cause the wire to fatigue and break. In addition, although some chargers use an automatic wire retractor (such as a wire winding and unwinding assembly driven by a coil spring), its structure is complex and bulky, and the modular disassembly of the wire cannot be achieved. The wire and the charger body are mostly integrally designed. After damage, the whole needs to be replaced, and the lack of modular repair ability is difficult to meet the flexible needs of different charging scenarios.

[0003] How to make the charging cable of the charger easier to store and occupy less storage volume has become one of the technical problems to be solved urgently at present. Summary of the Invention

[0004] In view of this, the present invention provides a charger with a recyclable charging cable that has a more reasonable structural design.

[0005] The technical solution of the present invention is realized as follows: The present invention provides a charger for recycling a charging cable, including: a charger body, an output cable, and an input cable. The output cable is plugged and installed on the surface of the charger body. An installation groove is provided on the surface of the charger body, and a cover plate is hinged at the opening of the installation groove. The input cable includes a rigid rod-shaped cable and a flexible connecting cable. Adjacent two rigid rod-shaped cables are detachably electrically connected by the flexible connecting cable. Plug heads and wiring terminals are respectively connected to the rigid rod-shaped cables at the ends. The wiring terminals are plugged and installed on the bottom surface of the installation groove and electrically connected to the charger body. After the flexible connecting cable is bent, multiple rigid rod-shaped cables can be parallelly arranged side by side in the installation groove.

[0006] The flexible connecting cable and the rigid rod-shaped cable are detachably connected. The rigid rod-shaped cable can keep the wires arranged in a highly parallel and side-by-side manner after storage, which is beneficial to improving the regularity of the storage structure and reducing the storage volume occupied. The overall input cable has a certain degree of flexibility through the flexible connecting cable, and the angle can be adjusted by bending at the position with the flexible connecting cable.

[0007] The above-mentioned rigid rod-shaped cable is a wire with a rigid insulating layer. After the flexible connecting cable is bent, multiple rigid rod-shaped cables are parallel to each other, so that they can be arranged parallelly side by side along the length or width direction of the installation groove, occupying a small space. Moreover, this structure allows the length of the input cable to be customized, and the length can be adjusted by setting different numbers of rigid rod-shaped cables.

[0008] In some embodiments, the flexible connecting wire is a flat wire, and the plane where the flat wire is located is perpendicular to the bottom surface of the installation groove.

[0009] The flat wire not only has good bending performance in one direction, which is beneficial to improving the bending service life, but also can limit its bending direction, so that the hard rod-shaped wire can be folded in a predetermined direction during folding and storage, avoiding difficult storage when the folding directions are inconsistent.

[0010] In some embodiments, a magnetic component is further included. A first ferromagnetic attachment is provided on the surface of the hard rod-shaped wire close to the bottom surface of the installation groove. The magnetic component is fixed on the bottom surface of the installation groove, and the magnetic component can selectively generate a magnetic field and adsorb and fix the first ferromagnetic attachment.

[0011] Providing a first magnetic attachment on the surface of the hard rod-shaped wire can cooperate with the magnetic component to achieve selective adsorption and fixation of the hard rod-shaped wire. The magnetic component is used to selectively generate a magnetic field, and the magnetic field can adsorb the first ferromagnetic attachment, thereby realizing the fixation of the corresponding hard rod-shaped wire.

[0012] The first magnetic attachment can be a layered structure made of ferromagnetic material, and this ferromagnetic layered structure is attached to the surface of the hard rod-shaped wire. It should be understood that the first magnetic attachment is not electrically connected to the conductor inside the hard rod-shaped wire.

[0013] In some embodiments, the magnetic component includes a fixing plate, an electromagnet, and magnetic conduction blocks. A plurality of magnetic conduction blocks are embedded in a linear array on the surface of the fixing plate, and the electromagnet is embedded inside the fixing plate and abuts against the magnetic conduction blocks. When the electromagnet generates a magnetic field, the magnetic conduction blocks are used to concentrate the magnetic field and adsorb and position the first ferromagnetic attachment.

[0014] In order to achieve the above-mentioned function of selective magnetic adsorption and fixation of the hard rod-shaped wire, the magnetic component uses an electromagnet in cooperation with magnetic conduction blocks to selectively generate a magnetic field. Among them, the magnetic conduction blocks are used for directional distribution of the magnetic field, so as to realize the positioning of the hard rod-shaped wire by using the distribution of the magnetic conduction blocks.

[0015] In some embodiments, the array arrangement direction of the magnetic conduction blocks is the same as the arrangement direction of the hard rod-shaped wire in the storage state, the distance between the magnetic conduction blocks is the same as the distance between the hard rod-shaped wires, and each magnetic conduction block corresponds to a hard rod-shaped wire.

[0016] In some embodiments, the projection of the ferromagnetic attachment on the surface of the fixing plate in the storage state coincides with the corresponding magnetic conduction block.

[0017] In some embodiments, a second ferromagnetic attachment is further included. The second ferromagnetic attachment is fixed to the side of the rigid rod-shaped wire away from the installation groove. The second ferromagnetic attachment abuts against the first ferromagnetic attachment. A third ferromagnetic attachment is provided on the surface of the cover plate close to the installation groove. When the cover plate is closed, the second ferromagnetic attachment can abut against the third ferromagnetic attachment.

[0018] In some embodiments, a buckle is further included. The buckle is fixed to the movable end of the cover plate, and the buckle can be selectively engaged with the bottom surface of the installation groove.

[0019] In some embodiments, in order to drive the electromagnet, a circuit structure for supplying power to the electromagnet is provided inside the charger body. The power source can come from an external power source or a power source built into the charger body, such as a battery. The way to control the opening and closing of the electromagnet can adopt a manual switch method, such as installing a switch on the power supply line.

[0020] The present invention has the following beneficial effects compared with the prior art:

[0021] The charger of the present invention uses a rigid rod-shaped wire and a flexible connecting wire to form an input wire. This input wire can achieve a more compact folding. The rigid rod-shaped wire makes the shape and size of the folded wire basically fixed, occupying less space, avoiding the irregularity of the folding of the overall flexible wire, and making the folding and arrangement easier.

Specific embodiments

[0031] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which the embodiments of the present invention belong. If the definitions stated in this section are contrary to or inconsistent with the definitions stated in the patents, patent applications, published patent applications, and other publications incorporated herein by reference, the definitions listed in this section shall prevail over the definitions incorporated herein by reference.

[0036] Unless otherwise specified, the methods used in the following embodiments are all conventional methods. The materials, reagents, and instruments used, unless otherwise specified, are all conventional materials, reagents, and instruments in this field, and those skilled in the art can obtain them through commercial channels.

[0037] As Figure 1 shown, in combination with Figures 2 - 7 , the charger of the recyclable charging cable of the present invention includes: a charger body 1, an output line 2, and an input line 3. The output line 2 is plugged and installed on the surface of the charger body 1. An installation groove 11 is opened on the surface of the charger body 1. A cover plate 12 is hinged at the opening of the installation groove 11. The input line 3 includes a rigid rod-shaped line 31 and a flexible connection line 32. Adjacent two rigid rod-shaped lines 31 are detachably electrically connected by the flexible connection line 32. The end rigid rod-shaped lines 31 are respectively connected with a plug 33 and a terminal 34. The terminal 34 is plugged and installed on the bottom surface of the installation groove 11 and is electrically connected to the charger body 1. After the flexible connection line 32 is bent, multiple rigid rod-shaped lines 31 can be parallel and arranged side by side and stored in the installation groove 11.

[0038] In the above embodiment solution, when storage is required, the input line 3 is folded. Specifically, multiple rigid rod-shaped lines 31 are bent by the flexible connection line 32 to be parallel or approximately parallel and arranged side by side, forming a flat storage structure, which is stored at the bottom of the installation groove 11. By covering the cover plate 12, storage is achieved. When use is required, the flexible connection line 32 extends, and multiple rigid rod-shaped lines 31 and the flexible connection line 32 form a straight or approximately straight unfolded structure. The flexible connection lines 32 at different positions can be bent to a certain extent to adapt to the bending requirements of the charging environment. During the charging process, the cover plate 12 is closed to protect one end of the input line 3 close to the charger body 1. It should be understood that one end of the installation groove 11 away from the terminal 34 is open to facilitate the unfolding of the input line 3.

[0039] In some embodiments, the flexible connection line 32 is a flat wire, and the plane where the flat wire is located is perpendicular to the bottom surface of the installation groove 11.

[0040] In the above embodiments, the flat wire has a better bending effect along its thickness direction and is difficult to bend along the width direction. Therefore, using the flat wire can achieve a certain degree of bending guidance, making the bending storage of the rigid rod-shaped wire 31 more orderly, avoiding mess during bending storage, and the bending radius of the flat wire is smaller when bending, which can make the rigid rod-shaped wires 31 close to each other after bending, occupying less space.

[0041] In some embodiments, it further includes a magnetic component 4. A first ferromagnetic attachment 5 is provided on one side surface of the rigid rod-shaped wire 31 close to the bottom surface of the installation groove 11. The magnetic component 4 is fixed on the bottom surface of the installation groove 11, and the magnetic component 4 can selectively generate a magnetic field and adsorb and fix the first ferromagnetic attachment 5.

[0042] The function of the magnetic component 4 is to selectively provide a magnetic field and use the magnetic field to fix the input wire 3 located in the installation groove 11. Specifically, a first magnetic attachment 5, such as an iron alloy shell, is fixed at the bottom of the rigid rod-shaped wire 31. When it is necessary to fix the rigid rod-shaped wire 31, the magnetic component 4 generates a magnetic field, thereby adsorbing the corresponding first magnetic attachment 5, and at this time, the position of the rigid rod-shaped wire 31 can be fixed.

[0043] In a specific embodiment, when it is necessary to fix the input wire 3 after folding and storing it, the magnetic component 4 generates a magnetic field. At this time, the folded state of the input wire 3 is fixed. After covering the cover plate 12, it can be stored. Magnetic fixation can keep the input wire 3 in a stable folded state even under bumpy conditions.

[0044] In some embodiments, the magnetic component 4 includes a fixing plate 41, an electromagnet 42, and a magnetic conduction block 43. A plurality of magnetic conduction blocks 43 are embedded in a linear array on the surface of the fixing plate 41. The electromagnet 42 is embedded inside the fixing plate 41 and the electromagnet 42 abuts against the magnetic conduction block 43. When the electromagnet 42 generates a magnetic field, the magnetic conduction block 43 is used to concentrate the magnetic field and adsorb and position the first ferromagnetic attachment 5.

[0045] In the above embodiments, as one of the realizable structures of the magnetic component 4, the fixing plate 41 is used to support the input wire 3, and at the same time, the electromagnet 42 and the magnetic conduction block 43 are carried, installed, and positioned. The electromagnet 42 can generate a magnetic field when energized, and the magnetic conduction block 43 is used to distribute the magnetic field generated by the electromagnet 42 in a directional manner, thereby realizing magnetic adsorption fixation with a positioning function.

[0046] For example, the magnetic conduction blocks 43 are arranged according to the positions after the rigid rod-shaped wires 31 are closely arranged. When the rigid rod-shaped wires 31 are closely arranged after storage, if it is necessary to maintain this close arrangement, the electromagnet 42 is turned on. At this time, the magnetic conduction blocks 43 concentrate the magnetic field and adsorb the first ferromagnetic attachments 5 at the corresponding positions, thereby realizing the adsorption and fixation of the corresponding rigid rod-shaped wires 31.

[0047] In some embodiments, the array arrangement direction of the magnetic conduction blocks 43 is the same as the arrangement direction of the hard rod-shaped wires 31 in the storage state, the distance between the magnetic conduction blocks 43 is the same as the distance between the hard rod-shaped wires 31, and each magnetic conduction block 43 corresponds to a hard rod-shaped wire 31.

[0048] The above embodiments are taken as an optimal implementation manner.

[0049] During the working process of the above embodiments, the magnetic component 4 can not only fix the input wire 3 in the storage state, but also magnetically adsorb and fix the input wire 3 located inside the installation groove 11 in the charging state. For example, when the length of the input wire 3 required for charging is not much, in order to avoid unnecessary damage caused by excessive exposure of the flexible connecting wire to the outside, the input wire 3 located inside the installation groove 11 can be magnetically adsorbed and fixed.

[0050] In some embodiments, the projection of the first ferromagnetic attachment 5 on the surface of the fixing plate 41 in the storage state coincides with the corresponding magnetic conduction block 43.

[0051] In the above embodiments, in order to achieve a more accurate positioning and stable adsorption effect, the shape of the first ferromagnetic attachment 5 is designed to coincide with the shape of the magnetic conduction block 43, and a more accurate positioning and adsorption fixation effect can be achieved.

[0052] In some embodiments, a second ferromagnetic attachment 6 is further included. The second ferromagnetic attachment 6 is fixed on the side of the hard rod-shaped wire 31 away from the installation groove 11. The second ferromagnetic attachment 6 abuts against the first ferromagnetic attachment 5. A third ferromagnetic attachment 7 is provided on the surface of the cover plate 12 close to the installation groove 11. When the cover plate 12 is closed, the second ferromagnetic attachment 6 can abut against the third ferromagnetic attachment 7.

[0053] In the above embodiments, the second ferromagnetic attachment 6 and the first ferromagnetic attachment 5 can be an integrally formed structure or a split structure. The second ferromagnetic attachment 6 is used to guide the magnetism of the first ferromagnetic attachment 5 above the hard rod-shaped wire 31. Thus, while magnetically adsorbing and fixing the hard rod-shaped wire 31, the hard rod-shaped wire 31 can also adsorb and fix the third ferromagnetic attachment 7 above and the corresponding cover plate 12. In this scenario, not only can the input wire 3 be fixed in the installation groove 11, but also the cover plate 12 can be fixed, thereby preventing the cover plate 12 from being accidentally opened and exposing the internal input wire 3. Better protection and storage effects are provided. Secondly, in some non-storage state usage scenarios, the cover plate 12 can also be prevented from being opened, and the input wire 3 below the cover plate 12 can also be protected.

[0054] In some embodiments, it further includes a buckle 8 which is fixed at the movable end of the cover plate 12, and the buckle 8 can be selectively clamped with the bottom surface of the installation groove 11.

[0055] The buckle provides a certain degree of insurance protection.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
