Referring to fig. 1, fig. 1 is a schematic perspective view of a charging cable 10 according to an embodiment of the present application, where the charging cable 10 according to an embodiment of the present application includes a cable main body 100, a plug 200, a protection sleeve 300, and a locking member 400; the plug 200 is connected with the cable main body 100, an extension part 210 is arranged at the end part of the plug 200, which is close to the cable main body 100, and the extension part 210 is fixedly arranged outside the cable main body 100; the protecting sleeve 300 is connected with the extension part 210, and the protecting sleeve 300 can be axially sleeved outside the cable main body 100 in a telescopic manner; the locking member 400 is used to lock the shield 300 to the cable body 100 or unlock the shield 300 from the cable body 100.
The charging cable 10 of the application can be applied to electric vehicles such as electric bicycles, motorcycles, electric tricycles and the like, and mainly plays a role in transmitting electric energy. One end of the cable main body 100 is electrically connected with a charger or an electric vehicle, and the other end of the cable main body 100 is electrically connected with a power supply through a plug 200. The plug 200 may be of a two-pin type or a three-pin type as shown in fig. 1, and the plug 200 may be integrally formed with the extension 210 of rubber.
Referring to fig. 2, an end of the cable body 100 near the plug 200 may be divided into a section a and a section B, where the section a is fixed in the extension 210, that is, the cable body 100 cannot slide in the extension 210, so that the cable body 100 cannot retract into the extension 210; the section B is not fixed in the protective sleeve 300, and the cable main body 100 and the protective sleeve 300 can move relatively, so that when the cable main body 100 breaks, the locking piece 400 is firstly used for locking the cable main body 100 by contacting the protective sleeve 300, and then the protective sleeve 300 is stretched towards the breaking part of the cable main body 100 so as to wrap the breaking part of the cable main body 100, thereby repairing the charging cable 10; then, the lock member 400 is used to lock the protection sleeve 300 to the cable main body 100.
It can be seen that, in the charging cable 10, the protection sleeve 300 can repair the breaking portion of the cable body 100 by virtue of the characteristic that the protection sleeve can axially stretch, and in the repair process, the cable body 100 cannot retract a certain length into the extension portion 210 due to the extension portion 210 being fixedly arranged outside the cable body 100, so that the effective length of the cable body 100 can be prevented from being changed.
In order to secure the connection strength of the protection cover 300 and the extension 210, the protection cover 300 and the extension 210 are integrally formed of rubber. In this application, referring to fig. 3, the protection sleeve 300 includes a first connection portion 310, a telescopic portion 320, and a second connection portion 330 connected in sequence, the first connection portion 310 is connected with the extension portion 210, the second connection portion 330 is connected with the locking member 400, and the telescopic portion 320 is of a bellows structure. The telescopic part 320 of the protective sleeve 300 adopts a bellows structure to realize the telescopic operation of a larger distance, so that the charging cable 10 can be repaired in a large range and multiple times. It will be appreciated that the extension 320 of the protective sheath 300 is required to be in a contracted and folded state when the charging cable 10 is shipped.
Of course, in other embodiments, the protective cover 300 may be made of an elastic material, such as a rubber material.
Referring to fig. 3, in some embodiments of the present application, the locking member 400 includes a support sleeve 410 and a detachable snap ring 420, the support sleeve 410 is used to support the protection sleeve 300 on the cable body 100, and the support sleeve 410 is fixed on the cable body 100 by the snap ring 420. The support sleeve 410 and the clamping ring 420 are matched, so that the protection sleeve 300 can be locked on the cable main body 100, and the protection sleeve has the characteristic of simple structure.
Further, in the present application, referring to fig. 3, the support sleeve 410 includes a mounting portion 411 and an elastic portion 412 connected to each other, and the snap ring 420 is provided at a position of the mounting portion 411 between the mounting portion 411 and the elastic portion 412; the mounting portion 411 is nested in the protective sleeve 300, the elastic portion 412 is located outside the protective sleeve 300 and is attached to the outer surface of the cable body 100, and when the cable body 100 is subjected to an external force, the bending curvature of the elastic portion 412 is greater than the bending curvature of the cable body 100 and less than the bending curvature of the extension portion 210. When an external force acts on the cable body 100, the bending of the elastic portion 412 is between the cable body 100 and the extension portion 210, so as to play a role in bending transition, and to avoid the problem that the connection portion between the extension portion 210 and the cable body 100 is prone to fatigue fracture due to the occurrence of a relatively obvious bending curvature difference as much as possible.
The elastic portion 412 may be made of a deformable material, such as a metal material. Wherein, referring to fig. 4, the elastic portion 412 may include a plurality of elastic pieces 4121, and the elastic pieces 4121 are arranged along the circumferential direction of the cable body 100. The elastic part 412 of the structure may be more easily deformed by external force, so that it may be ensured that the bending curvature of the elastic part 412 is greater than the bending curvature of the cable body 100 and less than the bending curvature of the extension part 210.
As for the number of the elastic pieces 4121, the embodiment of the present application is not particularly limited as long as the use requirement can be satisfied, and for example, 3, 4, 5, 6, 7, 8, etc. are set.
Wherein, referring to fig. 3 and 4, an end of the spring plate 4121 away from the extension portion 210 is bent towards the cable main body 100 to form a barb structure 4122, and the barb structure 4122 abuts against the outer surface of the cable main body 100. The barb 4122 and the spring 4121 can form secondary deformation to compensate for the bending of the cable body 100, that is, when the cable body 100 is bent, the spring 4121 and the barb 4122 can jointly deform, so that the problem that the single spring 4121 is easy to deform and fatigue is avoided.
Referring to fig. 3 and 4, in the present application, a flange structure 4111 is formed at an end of the mounting portion 411 adjacent to the extension portion 210 by bending toward the outside, a mounting cavity is provided in the protection sleeve 300, and the flange structure 4111 is fixed in the mounting cavity. By matching the flanging structure 4111 of the mounting portion 411 with the mounting cavity of the protective sleeve 300, the connection strength of the mounting portion 411 and the protective sleeve 300 can be improved. The flange structure 4111 of the mounting portion 411 may be fixed in the mounting cavity of the protective sleeve 300 by bonding, integral molding, or the like.
Referring to fig. 3, the inner surface of the mounting part 411 is provided with a sealing member 430, and the sealing member 430 is used to seal a gap between the mounting part 411 and the cable body 100. The sealing member 430 can seal the mounting portion 411 between the cable body 100 and the extension portion 210, and can ensure that the breaking portion between the cable body 100 and the extension portion 210 is covered in a relatively sealed space, so that the problem of potential safety hazard caused by water collision of the exposed metal wire at the breaking portion of the cable body 100 can be avoided, and the charging cable 10 of the present application can ensure the tightness of the cable body 100, the plug 200 and the breaking portion, whether the cable body 100 is repaired before or after breaking.
The sealing member 430 may be a sealing ring, the inner wall of the mounting portion 411 may be provided with a receiving groove, and the sealing member 430 may be mounted in the receiving groove by adhesion or the like.
Regarding the number of the sealing members 430, the embodiment of the present application is not particularly limited as long as the gap between the support sleeve 410 and the cable body 100 can be effectively sealed, and for example, may be set to 1, 2, 3 or more.
In the present application, the head and tail of the snap ring 420 have a gap of adjustable size. When the lock between the protective sleeve 300 and the cable main body 100 needs to be released, the gap between the head part and the tail part of the snap ring 420 is enlarged; when the protective cover 300 is required to be locked on the cable main body 100, the gap between the head and the tail of the clamping ring 420 is reduced. Wherein, after the protective cover 300 is locked on the cable main body 100, the head of the snap ring 420 may be connected to the tail of the snap ring 420 through a screw.
Another embodiment of the present application also provides an electric vehicle including the charging cable 10 as set forth in any one of the above.
The electric vehicle comprises an electric bicycle, a motorcycle and an electric tricycle. Referring to fig. 2, an end of the cable main body 100 of the charging cable 10 near the plug 200 may be divided into a section a and a section B, wherein the section a is fixed in the extension portion 210, that is, the cable main body 100 cannot slide in the extension portion 210, so that the cable main body 100 cannot retract into the extension portion 210; the section B is not fixed in the protective sleeve 300, and the cable main body 100 and the protective sleeve 300 can move relatively, so that when the cable main body 100 breaks, the locking piece 400 is firstly used for locking the cable main body 100 by contacting the protective sleeve 300, and then the protective sleeve 300 is stretched towards the breaking part of the cable main body 100 so as to wrap the breaking part of the cable main body 100, thereby repairing the charging cable 10; then, the lock member 400 is used to lock the protection sleeve 300 to the cable main body 100.
It can be seen that, in the charging cable 10 of the electric vehicle, the protection sleeve 300 can repair the breaking portion of the cable main body 100 by virtue of the characteristic that the protection sleeve can axially stretch, and in the repair process, the cable main body 100 cannot retract a certain length into the extension portion 210 due to the extension portion 210 being fixedly arranged outside the cable main body 100, so that the effective length of the cable main body 100 can be prevented from being changed.
In order to secure the connection strength of the protection cover 300 and the extension 210, the protection cover 300 and the extension 210 are integrally formed of rubber.

The telescopic part 320 of the protective sleeve 300 adopts a bellows structure to realize the telescopic operation of a larger distance, so that the charging cable 10 can be repaired in a large range and multiple times. It will be appreciated that the extension 320 of the protective sheath 300 is required to be in a contracted and folded state when the charging cable 10 is shipped.
Of course, in other embodiments, the protective cover 300 may be made of an elastic material, such as a rubber material.

The support sleeve 410 and the clamping ring 420 are matched, so that the protection sleeve 300 can be locked on the cable main body 100, and the protection sleeve has the characteristic of simple structure.
Further, in the present application, referring to fig. 3, the support sleeve 410 includes a mounting portion 411 and an elastic portion 412 connected to each other, and the snap ring 420 is provided at a position of the mounting portion 411 between the mounting portion 411 and the elastic portion 412; the mounting portion 411 is nested in the protective sleeve 300, the elastic portion 412 is located outside the protective sleeve 300 and is attached to the outer surface of the cable body 100, and when the cable body 100 is subjected to an external force, the bending curvature of the elastic portion 412 is greater than the bending curvature of the cable body 100 and less than the bending curvature of the extension portion 210. When an external force acts on the cable body 100, the bending of the elastic portion 412 is between the cable body 100 and the extension portion 210, so as to play a role in bending transition, and to avoid the problem that the connection portion between the extension portion 210 and the cable body 100 is prone to fatigue fracture due to the occurrence of a relatively obvious bending curvature difference as much as possible.
The elastic portion 412 may be made of a deformable material, such as a metal material. Wherein, referring to fig. 4, the elastic portion 412 may include a plurality of elastic pieces 4121, and the elastic pieces 4121 are arranged along the circumferential direction of the cable body 100. The elastic part 412 of the structure may be more easily deformed by external force, so that it may be ensured that the bending curvature of the elastic part 412 is greater than the bending curvature of the cable body 100 and less than the bending curvature of the extension part 210.
As for the number of the elastic pieces 4121, the embodiment of the present application is not particularly limited as long as the use requirement can be satisfied, and for example, 3, 4, 5, 6, 7, 8, etc. are set.
Wherein, referring to fig. 3 and 4, an end of the spring plate 4121 away from the extension portion 210 is bent towards the cable main body 100 to form a barb structure 4122, and the barb structure 4122 abuts against the outer surface of the cable main body 100. The barb 4122 and the spring 4121 can form secondary deformation to compensate for the bending of the cable body 100, that is, when the cable body 100 is bent, the spring 4121 and the barb 4122 can jointly deform, so that the problem that the single spring 4121 is easy to deform and fatigue is avoided.
Referring to fig. 3 and 4, in the present application, a flange structure 4111 is formed at an end of the mounting portion 411 adjacent to the extension portion 210 by bending toward the outside, a mounting cavity is provided in the protection sleeve 300, and the flange structure 4111 is fixed in the mounting cavity. By matching the flanging structure 4111 of the mounting portion 411 with the mounting cavity of the protective sleeve 300, the connection strength of the mounting portion 411 and the protective sleeve 300 can be improved. The flange structure 4111 of the mounting portion 411 may be fixed in the mounting cavity of the protective sleeve 300 by bonding, integral molding, or the like.
Referring to fig. 3, the inner surface of the mounting part 411 is provided with a sealing member 430, and the sealing member 430 is used to seal a gap between the mounting part 411 and the cable body 100. The sealing member 430 can seal the mounting portion 411 between the cable body 100 and the extension portion 210, and can ensure that the breaking portion between the cable body 100 and the extension portion 210 is covered in a relatively sealed space, so that the problem of potential safety hazard caused by water collision of the exposed metal wire at the breaking portion of the cable body 100 can be avoided, and the charging cable 10 of the present application can ensure the tightness of the cable body 100, the plug 200 and the breaking portion, whether the cable body 100 is repaired before or after breaking.
The sealing member 430 may be a sealing ring, the inner wall of the mounting portion 411 may be provided with a receiving groove, and the sealing member 430 may be mounted in the receiving groove by adhesion or the like.
Regarding the number of the sealing members 430, the embodiment of the present application is not particularly limited as long as the gap between the support sleeve 410 and the cable body 100 can be effectively sealed, and for example, may be set to 1, 2, 3 or more.
In the present application, the head and tail of the snap ring 420 have a gap of adjustable size. When the lock between the protective sleeve 300 and the cable main body 100 needs to be released, the gap between the head part and the tail part of the snap ring 420 is enlarged; when the protective cover 300 is required to be locked on the cable main body 100, the gap between the head and the tail of the clamping ring 420 is reduced. Wherein, after the protective cover 300 is locked on the cable main body 100, the head of the snap ring 420 may be connected to the tail of the snap ring 420 through a screw.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
