It should be noted that the terms "first", "second", and the like in the present disclosure are only used for distinguishing different devices, components, or mechanisms, and are not used for limiting the order or interdependence of the devices, components, or mechanisms.

Referring to fig. 1 and 2, the present disclosure provides a pivoting support base 100 for supporting a cable of a charging device, which includes a fixed charging device, a mobile charging device, and the like for charging an electric vehicle.

The swivel bearing 100 of the present disclosure includes a fixing base 110 and a hoop 120 for clamping a cable, and the hoop 120 is rotatably mounted on the fixing base 110.

Based on above-mentioned structure, because embrace hoop 120 and install on fixing base 110 with rotating, in using, cable conductor accessible embraces hoop 120 and presss from both sides the dress, when pulling the cable conductor, if the cable conductor rotates, hoop 120 can follow the rotation to for the cable conductor provides the degree of freedom of gyration, reduce the cable conductor winding.

For example, the fixing base 110 may have a mounting plate 111 and a mounting portion 112 for fixedly connecting with a casing of a charging device; the mounting plate 111 is fixedly connected with the mounting part 112; the hoop member 120 has a connecting portion 123, and the connecting portion 123 is rotatably mounted on the mounting plate 111 via a pivoting support 130. The connecting portion 123 may be a flange disposed at one end of the hoop member 120, a connecting lug disposed on the hoop member 120, or an installation screw hole disposed at an end of the hoop member 120. The slewing bearing 130 comprises an inner ring and an outer ring, wherein the outer ring is rotatably sleeved on the inner ring; for example, the outer ring of the slewing bearing 130 is fixedly connected to the mounting plate 111 of the fixing base 110, and the inner ring is fixedly connected to the connecting portion 123 of the hoop 120 by bolts. Because the inner ring and the outer ring of the rotary support 130 can rotate relatively, the hoop member 120 rotates relatively to the fixed seat 110, when in use, the cable passes through the inner ring of the rotary support 130 and the hoop member 120, and the cable is clamped on the hoop member 120, so that the cable and the hoop member 120 can rotate synchronously.

In one example, in order to facilitate clamping the cable and to enable the cable to be tightly connected to the hoop 120 after the cable is clamped, the hoop 120 includes a hoop main body 121 and a hoop sub-body 122, and the connecting portion 123 is disposed on the hoop main body 121; the anchor ear accessory 122 is detachably connected with the anchor ear main body 121 through fasteners such as bolts; when the anchor ear accessory 122 is connected to the anchor ear main body 121, a clamping space for clamping the cable is provided between the anchor ear accessory 122 and the anchor ear main body 121.

Based on the structure, when the cable is clamped, after one end of the cable passes through the clamping space, the hoop accessory 122 and the hoop main body 121 are gradually clamped by fasteners such as bolts, and the clamping space is gradually reduced until the hoop 120 is fastened and clamped on the cable, so that the hoop 120 and the cable can synchronously rotate; when the cable is pulled, the hoop 120 can rotate to provide a degree of freedom for the cable to rotate.

Because the cable of the charging gun generally has a longer length and a larger weight, after the cable extends out of the casing of the charging device, the cable is easy to directly drag on the floor due to lack of supporting force; on one hand, as the cable is dragged on the ground, the hoop member 120 cannot be driven to rotate when the cable rotates, so that the cable is wound and the like; on the other hand, because the cable conductor pulls subaerial, the user needs bigger strength to pull the cable conductor, just can make the rifle that charges remove to the position that the car charges the mouth, leads to the user to use to experience not good, in addition owing to pull the cable conductor, leads to cable conductor and ground friction, causes the damage of cable conductor easily.

In view of the above problem, the present disclosure provides another cable supporting device, which includes the aforementioned rotary supporting seat 100, and further includes an elastic supporting member 200 supported on the cable along an axial direction of the cable, wherein one end of the elastic supporting member 200 is clamped on the hoop member 120.

Based on above-mentioned structure, on the one hand, elastic support member 200 supports on the cable conductor along the cable conductor axial, and elastic support member 200's one end is installed on embracing hoop member 120, therefore, when dragging the cable conductor, elastic support member 200 can provide along the axial holding power of cable conductor for the cable conductor, avoid the cable conductor to drag to lead to the cable conductor can't drive to embrace hoop member 120 pivoted condition to take place subaerially, thereby make the user when dragging the cable conductor, if the cable conductor takes place to rotate, can drive through elastic support member 200 and embrace hoop member 120 to rotate, provide the degree of freedom of gyration for the cable conductor, reduce the cable conductor winding.

On the other hand, elastic support member 200 can provide axial holding power for the cable conductor, and install on embracing hoop member 120 because elastic support member 200's one end, therefore, when dragging the cable conductor, elastic support member 200 one end is relatively fixed in the axial of cable conductor, the other end can be dragged along with the cable conductor and rocks, make elastic support member 200 produce crooked elastic deformation, and then produce and drag the elasticity of moving opposite direction with the cable conductor, thereby provide for the cable conductor and drag the supporting moment who moves opposite direction with the cable conductor, this supporting moment not only reduces the user and pulls the required strength of cable conductor, promote user experience, and can avoid the cable conductor directly to pull subaerially, lead to the problem of cable conductor wearing and tearing.

Referring to fig. 1 and 2, as an implementation of the embodiment of the present disclosure, the elastic support 200 includes at least two elastic support portions supported on the electric cable in an axial direction of the electric cable. Taking the example that the elastic supporting member 200 includes two elastic supporting portions, the two elastic supporting portions are a first elastic supporting portion 201 and a second elastic supporting portion 202, respectively, the first elastic supporting portion 201 is connected to the hoop member 120, the second elastic supporting portion 202 is connected to the first elastic supporting portion 201, and the stiffness coefficient of the first elastic supporting portion 201 is greater than that of the second elastic supporting portion 202.

In practical application, the user drags the in-process of cable conductor, and required pulling force is not unchangeable, but increases along with the cable conductor pulls the distance, and when the cable conductor pulls the distance when being close, required pulling force is less, and when pulling the distance far away, required pulling force is big more, and consequently, the holding power that elastic support piece 200 provided also changes according to the change of pulling the distance. If elastic support member 200's coefficient of stiffness is too high, when dragging the distance near, elastic support member 200 can not produce sufficient deformation, restricts the degree of freedom that the user dragged the cable conductor on the contrary, leads to the cable conductor to drag more hard, and if elastic support member 200's coefficient of stiffness undersize, when dragging the distance far away, elastic support member 200 can't provide sufficient support moment again.

In view of the above problem, in the embodiment of the disclosure, the second elastic supporting portion 202 of the elastic supporting member 200 is closer to the charging gun than the first elastic supporting portion 201; since the stiffness coefficient of the first elastic supporting portion 201 connected to the hoop member 120 is greater than the stiffness coefficient of the second elastic supporting portion 202, when the cable is pulled, the second elastic supporting portion 202 is elastically deformed first to generate an elastic force opposite to the cable pulling direction, thereby providing a first stage of supporting moment opposite to the cable pulling direction for the cable; when continuing to drag the cable conductor, drag the power of cable conductor and constantly increase, the support moment in the first stage that second elastic support portion 202 produced is difficult to satisfy the moment demand of supporting the cable conductor, surpasss when the power of dragging the cable conductor and makes first elastic support portion 201 take place the critical value of deformation after, elastic deformation takes place for first elastic support portion 201 to provide for the cable conductor and drag the support moment of the opposite direction's second stage with the cable conductor.

In this embodiment, because the elastic support member 200 includes the first elastic support portion 201 and the second elastic support portion 202 that have different stiffness coefficients at least, in practical application, the second elastic support portion 202 is more easy for the first elastic support portion 201 to take place deformation, can provide comparatively less support moment, can enough provide certain support moment to the cable conductor, and can avoid because stiffness coefficient is too big, produce stronger and the user pulls the elasticity that the direction is opposite, cause the user to pull the problem of cable conductor difficulty. In addition, because the first elastic support part 201 has a large stiffness coefficient, a large support force can be exerted, and the cable is prevented from being directly dragged to the ground.

In one example, referring to fig. 3 and 4, the elastic support 200 has a passage 203 for passing the cable. The passage 203 penetrates the elastic support 200 in the axial direction of the elastic support 200. The cable conductor passes passageway 203, makes elastic support piece 200 can wrap up in the outside of cable conductor, plays 360 supports to the cable conductor, and the user can drag the cable conductor from arbitrary direction, and elastic support piece 200 homoenergetic plays the supporting effect.

In one example, referring to fig. 3, in one implementation of the present embodiment, the elastic support 200 may be a spring assembly; the spring assembly may include a first spring and a second spring. The first spring and the second spring can be of an integrated structure or of a split structure connected through a connecting piece. If the elastic support 200 is divided into the first elastic support 201 and the second elastic support 202, the first elastic support 201 may be a first spring and the second elastic support 202 may be a second spring. For example, the elastic support 200 may be formed by connecting two springs having different stiffness coefficients, and in order to make the stiffness coefficient of the first spring larger than that of the second spring, the first spring and the second spring at least include any one of the following three schemes:

under the condition that the first spring and the second spring are made of the same material and the diameter of the spring wire is the same, the pitch of the first spring can be smaller than that of the second spring, so that the stiffness coefficient of the first spring is larger than that of the second spring;

under the condition that the first spring and the second spring are made of the same material and the pitches of the first spring and the second spring are equal, the diameter of the spring wire of the first spring is larger than that of the spring wire of the second spring, so that the stiffness coefficient of the first spring is larger than that of the second spring;

and thirdly, selecting materials with different stiffness coefficients to respectively manufacture the first spring and the second spring so as to satisfy the requirement that the stiffness coefficient of the first spring is greater than that of the second spring.

In another example, referring to fig. 3, the elastic support 200 may be a variable pitch spring. The variable pitch spring may include a first partial spring and a second partial spring; the first elastic support 201 is a first partial spring, the second elastic support 202 is a second partial spring, and the pitch of the second partial spring is greater than that of the first partial spring. Since the pitch spring has at least two spring segments having different progression coefficients, a variable pitch spring integrally formed may be used as the elastic support 200.

In yet another example, referring to fig. 4, the elastic support 200 is an elastic sleeve. The elastic sleeve may include a first partial sleeve and a second partial sleeve; the first elastic support 201 is a first partial sleeve, and the second elastic support 202 is a second partial sleeve. The present embodiment may use a material with a certain stiffness coefficient to form the elastic sleeve, and the first sleeve portion and the second sleeve portion may use materials with different stiffness coefficients, or the first sleeve portion and the second sleeve portion may have different diameters, so that the first sleeve portion and the second sleeve portion have different stiffness coefficients.

To sum up, this disclosed cable conductor strutting arrangement can provide axial holding power for battery charging outfit's cable conductor, when dragging the cable conductor, produces crooked elastic deformation through elastic support piece 200, produces and drags the elasticity of moving opposite direction with the cable conductor to provide for the cable conductor and drag the supporting moment who moves opposite direction with the cable conductor, reduce the user and drag the required strength of cable conductor, promote user experience, and can avoid the cable conductor directly to drag subaerially, lead to the problem of cable conductor wearing and tearing.

Referring to fig. 1 to 5, embodiments of the present disclosure further provide a charging apparatus, including a cable 300, a charging gun 400, and a power supply device 500, and further including the rotary support 100 or the cable support device; one end of the cable 300 is connected with the charging gun 400, and the other end passes through the rotary supporting seat 100 or the cable supporting device to be connected with the power supply device 500; the rotary supporting seat 100 or the cable supporting device is arranged on the power supply device 500; when the charging apparatus includes the cable supporting device, the position of the end of the elastic supporting member 200 of the cable supporting device near the charging gun 400 is higher than the position of the hoop member 120.
