[0002] With the continuous advancement and popularization of electric vehicle technology, charging piles have become an indispensable infrastructure in the electric vehicle industry. Charging piles are mainly used to provide electric energy for electric vehicles (including pure electric vehicles and plug-in hybrid vehicles). In order to increase charging safety, some charging piles are currently equipped with airbags. When the charging pile collides with the car, the airbag pops out to cushion the impact on the charging pile. Although the airbag can play a cushioning role, since the airbag is between the charging pile and the car, it increases the risk of the charging pile tipping over. Summary of the invention

[0003] An object of the present invention is to provide a charging pile safety protection device, which can reduce the risk of the charging pile tipping over when it is hit.

[0004] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is: the embodiment of the present application provides a charging pile safety protection device, including a base, an insulating seat, a conductive component and a first airbag component. The base is provided with a spherical cavity, the spherical cavity is provided with a first opening, and the spherical cavity includes a bottom opposite to the first opening. The insulating seat is arranged opposite to the first opening and is used to install the electric pile body. The conductive component includes a conductive column, a conductive part, and a plurality of elastic support parts. The conductive column is connected to the insulating seat. The plurality of elastic support parts are arranged around the circumference of the conductive column. The elastic support part includes an overlapping section, a bending section, a matching section and a connecting section. The connecting section is connected to the insulating seat. The matching section is used to contact the side wall of the spherical cavity. The conductive part is arranged at the bottom, and the overlapping sections of the plurality of elastic support parts are stacked on the conductive part. The conductive column abuts against the top overlapping section among the plurality of overlapping sections. The first airbag component corresponds to the elastic support part one by one and is arranged in the bending section.

[0005] In some embodiments, a recessed portion is disposed on a surface of the conductive column, the recessed portion includes a second opening, and the conductive portion is provided with a flexible wall, the flexible wall closes the second opening of the recessed portion, and the flexible wall is attached to an inner wall surface of the recessed portion.

[0006] In some embodiments, the conductive column is further provided with an air channel, and the air channel is connected with the interior of the recessed portion.

[0007] In some embodiments, the conductive column includes a first wall facing the overlapping section and a peripheral wall connected to the first wall, the peripheral wall is inclined, and a surface of the peripheral wall is partially recessed to form a recessed portion.

[0008] In some embodiments, the electric pile body is provided with a plurality of detection components and a plurality of second airbag components around the circumference of the electric pile body.

[0009] In some embodiments, the detection component and the second airbag component correspond to positions of the elastic supporting portion, respectively.

[0010] In some embodiments, the base is also rotatably provided with multiple winding rollers, the multiple winding rollers are arranged around the circumference of the electric pile body, a torsion spring is arranged between the winding rollers and the base, the winding rollers are wound with connecting ropes, and the connecting ropes are connected to the insulating seat.

[0011] In some embodiments, the elastic support portion includes a metal portion and an insulating portion, the insulating portion is arranged on a side of the metal portion close to the conductive portion, a plurality of protrusions are arranged on the overlapping section facing the insulating portion, the insulating portion is provided with a through hole, the protrusions are passed through the through holes, and between two adjacent overlapping sections, the protrusion of one abuts against the metal portion of the other, and at the bending section, the metal portion and the insulating portion are both bent toward a side away from the conductive portion, and the first airbag component is arranged on the side of the metal portion facing the insulating portion.

[0012] In some embodiments, the distances between the connection points between each elastic support portion and the insulating seat and the conductive pillar are different.

[0013] The present invention has the following beneficial effects:

[0014] When the electric pile body collides, the first airbag component of the elastic support part close to the impacted side of the electric pile body pops out the airbag. On the one hand, the airbag exerts a force on the inner wall of the spherical cavity, so that the electric pile body can rotate in the direction away from the collision side, buffering the impact force on the electric pile body, and when the airbag component arranged on the electric pile body pops out the airbag, the risk of the electric pile body tipping over due to the thrust generated by the airbag on the electric pile body is reduced. On the other hand, since multiple elastic support parts are arranged around the circumference of the conductive column, and the ball-like structure formed by the elastic support part cooperates with the spherical cavity, the impact force on the electric pile body can be buffered when the electric pile body is hit from different sides. On the other hand, after the airbag of the first airbag component is popped out, under the lifting action of the airbag, the overlapping section of the elastic support part of the first airbag component and the overlapping section of the elastic support part below are separated, so that the electric pile body can be disconnected from the power supply, reducing the risk of the electric pile body being short-circuited due to the impact.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0022] See also Figure 1 and Figure 2 , the embodiment of the present application provides a charging pile safety protection device, including a base 1, an insulating seat 7, a conductive component and a first airbag component 4. The base 1 is provided with a spherical cavity 6, the spherical cavity 6 is provided with a first opening, and the spherical cavity 6 includes a bottom opposite to the first opening. The insulating seat 7 is arranged opposite to the first opening and is used to install the electric pile body 8. The conductive component includes a conductive column, a conductive part 2, and a plurality of elastic support parts 3. The conductive column is connected to the insulating seat 7. The plurality of elastic support parts 3 are arranged around the circumference of the conductive column. The elastic support part 3 includes an overlapping section 13, a bending section 14, a matching section 15 and a connecting section 16. The connecting section 16 is connected to the insulating seat 7. The matching section 15 is used to contact the side wall of the spherical cavity 6. The conductive part 2 is arranged at the bottom, and the overlapping sections 13 of the plurality of elastic support parts 3 are stacked on the conductive part 2. The conductive column abuts against the top overlapping section 13 among the plurality of overlapping sections 13. The first airbag component 4, corresponding to the elastic support part 3 one by one, is arranged at the bending section 14.

[0023] The insulating seat 7 is made of non-conductive material. The specific material can be selected from the existing materials and will not be described in detail here.

[0024] The charging pile body 8 is a component used to charge the car. Its structure and working principle are well known to those skilled in the art and will not be described in detail here.

[0025] The conductive column is electrically connected to the electric pile body 8 .

[0026] The side wall is the portion where the inner wall of the spherical cavity 6 is connected to the bottom.

[0027] The conductive part 2 is used to connect to an external power source, the conductive column is electrically connected to the electric pile body 8, the conductive column abuts against the overlapping section 13, and the overlapping section 13 abuts against the conductive part 2, so that the conductive part 2 and the conductive column are electrically connected, and external electrical energy can be input into the electric pile body 8.

[0028] On the one hand, the elastic support part 3 is used to form a part that cooperates with the spherical cavity 6, so that the insulating seat 7 can rotate relative to the spherical cavity 6, that is, each elastic support part 3 and the spherical cavity 6 include two contact parts, one is an overlapping section 13, and the other is a matching section 15, so that multiple elastic support parts 3 can form a structure similar to a ball head. The ball head structure cooperates with the spherical cavity 6, so that the insulating seat 7 can rotate relative to the base 1. Compared with the traditional integral ball head, the processing accuracy requirements for the spherical cavity 6 are reduced, and the cost is reduced. On the other hand, the elastic support part 3 is made of a material that can produce elastic deformation, so that the elastic support part 3 can also play a buffering role and can buffer the vibration generated when the electric pile body 8 is working. On the other hand, the elastic support part 3 can also play a switch role, that is, when the two adjacent overlapping sections 13 are separated, the connection between the external power supply and the electric pile body 8 is disconnected.

[0029] The first airbag component 4 is a component capable of ejecting an inflated airbag, and its structure and working principle are well known to those skilled in the art and will not be described in detail herein.

[0030] The bent section 14 can provide an installation position for installing the first airbag component 4 .

[0031] When the electric pile body 8 collides, the first airbag component 4 of the elastic support part 3 near the impacted side of the electric pile body 8 pops out the airbag. On the one hand, the airbag generates a force on the inner wall surface of the spherical cavity 6, so that the electric pile body 8 can rotate in the direction away from the collision side, buffering the impact force on the electric pile body 8, and when the airbag component arranged on the electric pile body 8 pops out the airbag, the risk of the electric pile body 8 tipping over due to the thrust generated by the airbag on the electric pile body 8 is reduced. On the other hand, since multiple elastic support parts 3 are arranged around the circumference of the conductive column, and the ball-like structure formed by the elastic support part 3 cooperates with the spherical cavity 6, the impact force on the electric pile body 8 can be buffered when the electric pile body 8 is impacted from different sides. On the other hand, when the airbag of the first airbag component 4 pops out, under the lifting action of the airbag, the overlapping section 13 of the elastic support part 3 of the first airbag component 4 is separated from the overlapping section 13 of the elastic support part 3 below, so that the electric pile body 8 can be disconnected from the power supply, reducing the risk of the electric pile body 8 being short-circuited by impact.

[0032] See also Figure 3 In some embodiments, a recessed portion 19 is provided on the surface wall of the conductive column, the recessed portion 19 includes a second opening, and the conductive portion 2 is provided with a flexible wall 18, the flexible wall 18 closes the second opening of the recessed portion 19, and the flexible wall 18 is attached to the inner wall surface of the recessed portion 19.

[0033] The flexible wall 18 closes the second opening of the recess 19, so that when the recess 19 is inflated, the flexible wall 18 can also expand. The chamber structure formed by the expansion of the flexible wall 18 is used to disconnect the conductive column and the overlapping section 13 in contact with it, further reducing the risk of short circuit when the electric pile body 8 is hit.

[0034] The flexible wall 18 is fitted to the inner wall surface of the recessed portion 19 , so that the flexible wall 18 can be received in the recessed portion 19 in the initial state, thereby reducing the risk of damage to the flexible wall 18 .

[0035] See also Figure 3 In some embodiments, the conductive column is further provided with an air channel 17 , and the air channel 17 is connected to the interior of the recessed portion 19 .

[0036] The recessed portion 19 can be inflated through the air passage 17 , and the gas source input into the air passage 17 can be selected as needed. For example, gas can be input into the recessed portion 19 through an inflatable component, or gas generated when an airbag is ejected through an airbag component can be partially input into the air passage 17 .

[0037] See also Figure 3 In some embodiments, the conductive column includes a first wall 20 facing the overlapping section 13 and a peripheral wall 21 connected to the first wall 20 , the peripheral wall 21 is inclined, and the surface of the peripheral wall 21 is partially recessed to form the recessed portion 19 .

[0038] The peripheral wall 21 is inclined in such a manner that the cross-sectional area of ​​the conductive pillar gradually decreases from the side of the peripheral wall 21 away from the first wall 20 to the side close to the first wall 20 .

[0039] The advantage of such a configuration is that when the flexible wall 18 expands, the flexible wall 18 can prevent the peripheral wall 21 of the conductive column and the first wall 20 from contacting the overlapping section 13 , thereby increasing the reliability of power-off of the electric pile body 8 .

[0040] See also Figure 1 In some embodiments, a plurality of detection components 9 and a plurality of second airbag components 10 are provided around the circumference of the electric pile body 8 .

[0041] The detection component 9 is used to determine whether the electric pile body 8 is hit, and thereby control the corresponding first airbag component 4 to pop out the airbag.

[0042] The detection component 9 can be selected from existing products. In general, the detection component may include a sensor and a processor. The sensor is used to determine whether the electric pile body 8 is hit, and the processor is used to control the operation of the first airbag component 4. Among the multiple detection components 9, only one processor may be provided, and the multiple sensors and the multiple first airbag components 4 may be controlled to operate by the one processor.

[0043] It should be noted that the specific circuits for electrically connecting the sensor and the first airbag component 4 to the processor, and the programming codes for controlling the operation of the sensor and the first airbag component 4 are well known to those skilled in the art and will not be elaborated here.

[0044] The second airbag component 10 is used to pop out when the electric pile body 8 is hit, so as to protect the electric pile body 8. The second airbag component 10 is a component capable of ejecting an inflatable airbag, and its structure and working principle are well known to those skilled in the art and will not be described in detail here.

[0045] In some embodiments, the detection component 9 and the second airbag component 10 correspond to the positions of the elastic supporting portion 3 respectively.

[0046] The positions of the detection component 9 and the second airbag component 10 correspond, that is, each detection component 9 and the second airbag component 10 are respectively located on the same side of the electric pile body 8 as each elastic support part 3. On the one hand, it is convenient for the detection component 9 to detect the impact on different sides of the electric pile body 8, and on the other hand, the second airbag component 10 corresponds to the elastic support part 3, so that when the second airbag component 10 pops out, the first airbag component 4 on the same side can pop out.

[0047] See also Figure 1In some embodiments, the base 1 is also rotatably provided with a plurality of winding rollers 11, the plurality of winding rollers 11 are circumferentially arranged around the electric pile body 8, a torsion spring is arranged between the winding rollers 11 and the base 1, the winding rollers 11 are wound with connecting ropes 12, and the connecting ropes 12 are connected to the insulating seat 7.

[0048] The torsion spring is used to provide an elastic force for returning the winding roller 11 to its original position.

[0049] The connecting rope 12 is connected to the insulating seat 7, which reduces the risk of the insulating seat 7 being separated from the base 1 when the insulating seat 7 rotates relative to the base 1, and reduces the risk of the electric pile body 8 tipping over.

[0050] See also Figure 4 In some embodiments, the elastic support portion 3 includes a metal portion 23 and an insulating portion 22. The insulating portion 22 is arranged on a side of the metal portion 23 close to the conductive portion 2. The overlapping section 13 is provided with a plurality of protrusions 24 on the side of the insulating portion 22. The insulating portion 22 is provided with a through hole. The protrusions 24 are passed through the through holes. Between two adjacent overlapping sections 13, the protrusions 24 of one abut against the metal portion 23 of the other. At the bending section 14, the metal portion 23 and the insulating portion 22 are both bent toward a side away from the conductive portion 2. The first airbag component 4 is arranged on a side of the metal portion 23 facing the insulating portion 22.

[0051] The metal portion 23 is made of a metal material capable of elastic deformation.

[0052] The protrusion 24 is disposed through the through hole, so that between two adjacent overlapping sections 13 , the protrusion 24 of one abuts against the metal portion 23 of the other, thereby enabling the two adjacent overlapping sections 13 to be electrically connected.

[0053] At the bending section 14 , the metal part 23 and the insulating part 22 are both bent toward a side away from the conductive part 2 , so that an installation space can be formed between the insulating part 22 and the metal part 23 , which is convenient for installing the first airbag component 4 .

[0054] The first airbag component 4 is arranged on the side of the metal part 23 facing the insulating part 22, so that when the first airbag component 4 pops out the airbag, the airbag can generate a thrust on the insulating part 22. At this time, the insulating part 22 is deformed toward the side close to the conductive part 2, and the metal part 23 rotates toward the side away from the conductive part 2, so that the protrusion 24 and the through hole can be misaligned. At this time, the protrusion 24 abuts against the insulating part 22, so that the two adjacent overlapping sections 13 cannot be electrically connected, thereby improving the power-off reliability of the electric pile body 8.

[0055] When the metal part 23 and the insulating part 22 are connected, they can be connected at the connecting section 16 .

[0056] In some embodiments, the distances between the connection points between each elastic support portion 3 and the insulating seat 7 and the conductive pillar are different.

[0057] That is, the distances between the connection sections 16 of the elastic support parts 3 and the connection points of the insulating seat 7 and the conductive pillars are different.

[0058] The advantage of such a configuration is that, on the one hand, the elastic support portion 3 can be in a deformed state, so that the two adjacent overlapping sections 13 can be closely abutted against each other, and the matching section 15 can be closely abutted against the side wall of the spherical cavity 6. On the other hand, when the first airbag component 4 pops out, a moving space is provided for the insulating seat 7 to rotate relative to the base 1.

[0059] The above embodiments are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
