Description

Modular charging pile and expandable structure

Technical Field

The present invention relates to the field of charging of new energy equipment, and in particular to a modular charging pile and an expandable structure.

Background technique

With the popularization of electric vehicles and the promotion of the concept of green travel, charging piles, as an important part of the electric vehicle industry chain, have seen explosive growth in both quantity and functional requirements. In order to meet diverse market demands and improve the convenience of charging services, modular charging pile technology has emerged. With the continuous expansion of the electric vehicle market and the continuous advancement of technology, modular charging piles will occupy an important position in the future construction of charging infrastructure due to their flexibility, scalability and easy maintenance. At the same time, with the promotion of new energy policies and consumers' recognition of the concept of green travel, the market prospects for modular charging piles are very broad, but modular design is also accompanied by problems such as heat dissipation.

For example: the Chinese invention patent (application number: CN202311005410.0) discloses a "modularly assembled new energy charging pile". Its specification discloses: each module is classified according to its function and arranged in the shell, which can be convenient for assembly and maintenance. However, in actual use, the modules are separated and no corresponding heat dissipation channels can be reserved. The heat of the current module can only be passively dissipated during operation. The heat generated by the current module is often due to the lack of heat dissipation and ventilation channels in the modular device. In the case of heat accumulation, it is easy to affect the overall durability. In addition, the connection stability with the external cable through the terminal plug-in is poor, and there is room for improvement. The above patents can prove the defects of the prior art.

Therefore, we made improvements to this and proposed modular charging piles and expandable structures.

Compared with the prior art, the present invention has the following beneficial effects:

In the scheme of this application:

1. In order to solve the problem that the corresponding heat dissipation channels cannot be reserved when the modules are separately arranged in the prior art, the heat of the current module can only be passively dissipated when working, and the heat generated by the current module is often due to the lack of heat dissipation and ventilation channels in the modular device, which is easy to affect the overall durability and life in the case of heat accumulation. The present application sets a functional module structure, uses a hinge plate and a telescopic magnetic plate to separate two adjacent functional module structures vertically downward, so as to directly form a ventilation channel between the two adjacent functional module structures, and sets an electromagnet on the inner side of the hinge plate on both sides of the box body, and sends the boxes out of the heat dissipation slot one by one and splices them, so that after the multiple boxes are spliced, the hinge plates and telescopic magnetic plates on both sides are unfolded, so as to protect the vehicle from rain and sun, and realize the heat dissipation inside the charging pile. After the structural transformation, it can form a sunshade and rainproof roof after extending from the inside of the heat dissipation slot to protect the vehicle;

2. In order to solve the problem in the prior art that the charging pile is idle and useless when the vehicle is not charged, the functional module structure provided in the present application is extended from the heat dissipation slot and then unfolded. At this time, the functional module structure can play a sunshade effect and protect the vehicle after splicing. At the same time, a solar panel is fixedly installed on the top of the box. In sunny weather, the solar panel can fully utilize light energy to generate electricity, which can not only shade the vehicle from the sun and rain, but also can be used as a power generation device to transmit the generated electricity to the power grid for sale when it is idle;

3. The driving structure is provided to support the functional module structure and fix the functional module structure with the partition at the top. When the lifting plate is driven by the electric cylinder, the functional module structure inside the charging pile can be sent to the top one by one by moving up and down. Then, the first motor drives the push plate to move by using the threaded rod to send the functional module structure out of the heat dissipation slot one by one and splice it. This realizes that the driving structure can not only fix the functional module structure, but also send the functional module structure out from the inside of the charging pile after the structural change.

4. Through the coordination of the extended structure and the multiple functional module structures set inside the charging pile, the second motor on the top of the docking terminal drives the driving gear and the rack to mesh with each other, thereby driving the docking terminal to move outside the powered bottom plate, and then select the function through the control box, and then drive the docking terminal to move to the specified position through the second motor and then dock and connect with the power-on hole on the powered bottom plate, so as to dock with different modules and dock according to different needs and different functional module structures, achieving wider applicability and flexibility;

5. Through the extended structure, when the second motor drives the docking terminal to move to the specified position, the limit balls arranged inside the sliding plates on both sides of the docking terminal are inserted into the positioning grooves opened on the inner side of the limit slide grooves under the elastic support of the reset springs, thereby realizing the precise positioning of the docking terminal. When the docking terminal moves to the specified position, the power-on hole is energized, and under the action of the electromagnetic suction, the power-on terminal is sucked out from the inside of the docking terminal and connected to the inside of the power-on hole, thereby realizing the energization of the connecting wire. When the power-on terminal is not docked with the power-on hole and is located inside the docking terminal due to the magnetic attraction of the magnetic ring, the connecting wire is not energized and the charging head is not energized, thereby protecting the equipment and operators and preventing accidental injuries.

Detailed ways

In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

As described in the background technology, in actual use, it is impossible to reserve corresponding heat dissipation channels when the modules are separately arranged. The heat of the current module can only be passively dissipated when working. The heat generated by the current module is often due to the lack of heat dissipation and ventilation channels in the modular device, which can easily affect the overall durability when heat accumulates.

In order to solve this technical problem, the present invention provides a modular charging pile and an expandable structure, which are applied to a new energy vehicle charging pile.

Specifically, please refer to Figures 1, 2, 4, 5 and 8. The modular charging pile specifically includes a charging pile 1, a panel 101 is fixedly installed on the front of the charging pile 1, heat dissipation grooves 103 are equidistantly opened on the surface of the panel 101, and guide grooves 104 are symmetrically opened on the top of the panel 101. Control boxes 105 are fixedly installed on both sides of the charging pile 1, and a protruding groove 102 is opened on the front of the panel 101;

Five functional module structures 2 are equidistantly arranged in the middle of the inner cavity of the charging pile 1. The functional module structure 2 includes a box body 201. Both sides of the box body 201 are movably hinged with hinge plates 203. The inner sliding sleeve of the hinge plate 203 is provided with a telescopic magnetic plate 204. A pair of docking grooves 206 are symmetrically opened on the inner side of the top of the box body 201. A pair of installation grooves 207 are symmetrically opened on the outer side of the top of the box body 201. The inner sliding sleeve of the installation groove 207 is provided with a docking plate 208.

The box body 201 is located at the top inner side of the heat dissipation groove 103, the heat dissipation holes of the box body 201 are opened at the bottom of the box body 201, the docking plate 208 is slidably connected to the inside of the guide groove 104, and the driving structure 3 is provided inside the charging pile 1;

Through the magnetism of the outer end of the docking plate 208, when the docking plate 208 moves to the tail of the previous box 201, the electromagnet 205 is energized to generate magnetic force, and the outer end of the docking plate 208 is magnetic, and produces a repulsive reaction with the magnetism generated by the electromagnet 205, so that the docking plate 208 slides out from the inside of the installation groove 207 and is adsorbed to the inside of the docking groove 206 opened at the tail of the previous box 201, thereby realizing the fixed connection of the two boxes 201. At this time, the electromagnets 205 on both sides of the box 201 are energized to generate magnetism. When the box 201 is completely extended from the inside of the extension groove 102, the electromagnet 205 produces a repulsive reaction to the telescopic magnetic plate 204. At this time, the telescopic magnetic plate 204 will expand horizontally and then slide from the inside of the hinged plate 203 to the outside.

The modular charging pile provided by the present invention, through the functional module structure 2, uses the hinged plate 203 and the telescopic magnetic plate 204 to separate two adjacent functional module structures 2 vertically downward, so that a ventilation channel is directly formed between the two adjacent functional module structures 2, and an electromagnet 205 is arranged on the inner side of the hinged plate 203 on both sides of the box 201. By sending the boxes 201 out from the inside of the extension groove 102 one by one and splicing them, so that a plurality of boxes 201 are spliced and the hinged plates 203 and the telescopic magnetic plates 204 on both sides are unfolded, the vehicle is shielded from rain and sun, and heat is conveniently dissipated inside the charging pile 1. After the structural transformation, it can form a sunshade and rainproof roof after extending from the inside of the extension groove 102 to protect the vehicle.

In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition and explanation in the subsequent drawings.

Example 1

Please refer to Figure 5, the modular charging pile has limit baffles 209 fixedly installed on both sides of the top of the box 201, and the solar panel 202 is fixedly installed on the top of the box 201. The rotation of the hinged plates 203 on both sides is limited by the limit baffles 209. When the solar panel 202 is unfolded and exposed to the sun, the solar panel 202 will use light energy to generate electricity.

After the box body 201 is extended from the extension slot 102 by the set functional module structure 2, it is unfolded. At this time, the functional module structure 2 can play a sunshade effect and protect the vehicle after splicing. At the same time, a solar panel 202 is fixedly installed on the top of the box body 201. In sunny weather, the solar panel 202 can fully utilize light energy to generate electricity, which can not only shade the vehicle from the sun and rain, but also be used as a power generation device to transmit the generated electricity to the power grid for sale when idle.

Please refer to Figures 1, 2 and 5. The modular charging pile has a magnetic outer end of the docking plate 208. When the electromagnet 205 is energized and magnetic, the electromagnet 205 and the docking plate 208 produce a repulsive reaction. At this time, the docking plate 208 will slide outward and be stuck in the docking slot 206 opened at the tail of the previous box 201, thereby fixing the two boxes 201. When the box 201 is retracted, the electromagnets 205 are powered off one by one and a reverse current is passed, so that the electromagnets 205 carry different magnetism and produce an adsorption effect on the docking plate 208 and the telescopic magnetic plate 204, so that the docking plate 208 inside the docking slot 206 that enters the extension slot 102 is retracted into the installation slot 207 again, thereby retracting the box 201 one by one. The five functional module structures 2 are respectively a fast charging module, a slow charging module, a data interaction module, a grid connection module, and a photovoltaic power generation module.

Example 2

The modular charging pile provided in Example 1 is further optimized. Specifically, as shown in Figures 4, 6 and 7, the driving structure 3 includes two lifting plates 301 and a partition 308. The partition 308 is fixedly installed in the middle of the inner cavity of the charging pile 1 and is located on the top of the functional module structure 2. A pair of sliding grooves 309 are symmetrically opened on the surface of the partition 308. A push plate 311 is slidably connected between the two sliding grooves 309. A first motor 310 is provided on the inner side of the push plate 311. The output end of the first motor 310 is transmission-connected with a threaded rod 312, and the threaded rod 312 is sleeved in the middle of the push plate 311. An electric cylinder 313 is fixedly installed on the top of the inner cavity of the charging pile 1. The tops of the two lifting plates 301 are fixedly connected. There is a fixed plate 314, which is fixedly connected to the telescopic end of the electric cylinder 313. Five limit plates 302 are equidistantly arranged on the inner side of the lifting plate 301. The limit plates 302 are movably hinged to the inner side of the lifting plate 301 through a torsion spring. Five extrusion blocks 303 are equidistantly fixedly installed on the outer side of the lifting plate 301. Five support plates 304 are equidistantly arranged on the inner walls of both sides of the inner cavity of the charging pile 1. The outer side of the support plate 304 is fixedly connected to a support spring 306. The inner ends of the support spring 306 are fixedly installed with limit strips 305. The two limit strips 305 are respectively located on both sides of the lifting plate 301. An arc-shaped protrusion 307 is provided on the inner bottom of the support plate 304. The surface of the arc-shaped protrusion 307 is smooth. The slide is arc-shaped, and the top and bottom outer sides of the extrusion block 303 are arc-shaped and matched with the arc-shaped protrusion 307. The sliding groove 309 is located directly above the docking groove 206 opened at the top of the box body 201, and the bottoms of the two ends of the push plate 311 are located directly above the docking groove 206. When the first motor 310 drives the threaded rod 312 to control the push plate 311 to send the first box body 201 out of the charging pile 1 through the extension groove 102, the electric cylinder 313 drives the fixed plate 314 to move the lifting plates 301 on both sides up and down, and then the limiting plates 302 on the inner side of the lifting plates 301 are clamped to the sides of the bottom of the hinged plates 203 on both sides of the box body 201, and the lower boxes 201 are moved upward one by one. After the lifting plate 301 is lifted to a certain height, when the lifting plate 301 moves upward, the extrusion block 303 on the outer side of the lifting plate 301 squeezes the arc-shaped protrusion 307 on the inner bottom of the support plate 304, so that the support plate 304 moves inward with the limiting bar 305. When the top of the hinge plate 203 contacts the limiting bar 305 above, the limiting bar 305 moves outward. Then, when the box 201 moves to the top of the limiting bar 305, the limiting bar 305 extends out again under the support of the support spring 306 and snaps into the bottom of the hinge plate 203 to support the moving box 201, so that the boxes 201 move to the highest position one by one, and then the boxes 201 are sent out one by one by the push plate 311.

When the box body 201 is retracted into the interior of the charging pile 1, the top box body 201 is supported by the limit plate 302 inside the lifting plate 301, and then the lifting plate 301 is moved down, bringing the functional module structure 2 down, and the arc-shaped protrusion 307 at the bottom inside the support plate 304 of the same height is squeezed by the extrusion block 303 outside the lifting plate 301, so that the limit bar 305 moves inward, so that the lifting plate 301 is lowered, and the functional module structure 2 is moved to the second limit bar 305 for placement, and then the first limit plate 302 at the top is energized and magnetically conductive, so that the first limit plate 302 at the top is adsorbed to the side of the lifting plate 301 and vertically upward. When the first limit plate 302 rises to the highest point again, the limit plate 302 is powered off again, so that the first limit plate 302 on the top receives the next functional module structure 2, and then the two functional module structures 2 inside are moved down at the same time again. At this time, the extrusion block 303 squeezes the support plate 304 at the same height, so that the limit bar 305 moves inward, and then the functional module structure 2 is moved down and placed on the limit bar 305 below. When moving up again, the two limit plates 302 on the top need to be energized to move the lifting plate 301 up, and so on, so that the external functional module structures 2 are moved one by one to the inside of the charging pile 1.

By setting up the driving structure 3, the functional module structure 2 can be supported, and the functional module structure 2 can be fixed in cooperation with the partition 308 on the top. When the lifting plate 301 is driven by the electric cylinder 313, the up and down movement can send the functional module structure 2 inside the charging pile 1 to the top one by one, and then the first motor 310 uses the threaded rod 312 to drive the push plate 311 to move, so that the functional module structure 2 is sent out from the extension groove 102 one by one and spliced, so that the driving structure 3 can not only fix the functional module structure 2, but also send the functional module structure 2 out from the inside of the charging pile 1 after the structural change.

Furthermore, as shown in Figures 6 and 7, the limit plate 302 is an electromagnet, which can generate magnetism and vertically adsorb to the inner side of the lifting plate 301 when energized. When the limit plate 302 is rotated inward by the torsion spring, the maximum rotation angle is thirty degrees clockwise.

By cooperating with the extended structure 4 and the multiple functional module structures 2 set inside the charging pile 1, the second motor 412 on the top of the docking terminal 406 drives the driving gear 413 and the rack 414 to engage with each other, thereby driving the docking terminal 406 to move on the outside of the powered base plate 401, and then the function is selected through the control box 105, and then the docking terminal 406 is driven by the second motor 412 to move to the specified position and then dock with the power-on hole 402 on the powered base plate 401, so as to dock with different modules and dock according to different needs and different functional module structures 2, thereby achieving wider applicability and flexibility.

Furthermore, as shown in Figures 9 and 11, limiting grooves 404 are symmetrically provided on both sides of the inner cavity of the guide sleeve 403, and sliding plates 407 are fixedly installed on both sides of the docking terminal 406. The sliding plates 407 are slidably engaged in the inside of the limiting grooves 404, and a return spring 408 is fixedly installed in the middle of the sliding plate 407. The outer side of the return spring 408 is fixedly connected to a limiting ball 409, and a positioning groove 415 is provided on the inner side of the limiting groove 404 at the same horizontal height as the power-on hole 402. The limiting ball 409 is slidably engaged in the positioning groove 415 provided on the inner side of the limiting groove 404. A magnetic ring 411 is fixedly installed on the bottom of the inner cavity of the docking terminal 406, and a connecting wire 107 is fixedly connected to the outer side of the power-on terminal 410. The other end of the connecting wire 107 is fixedly connected to the charging head 106, and the charging head 106 is inserted into the control box 105.

When the second motor 412 is used to drive the docking terminal 406 to move to the specified position, the limiting balls 409 arranged inside the sliding plates 407 on both sides of the docking terminal 406 are elastically supported by the return springs 408 and are inserted into the positioning grooves 415 opened on the inner side of the limiting slide grooves 404, thereby realizing the precise positioning of the docking terminal 406. When the docking terminal 406 moves to the specified position, the power-on hole 402 is energized. Under the action of the electromagnetic suction, the power-on terminal 410 is sucked out from the inside of the docking terminal 406 and connected to the inside of the power-on hole 402, thereby realizing the power-on of the connecting wire 107. When the power-on terminal 410 is not docked with the power-on hole 402 and is located inside the docking terminal 406 due to the magnetic attraction of the magnetic ring 411, the connecting wire 107 is not energized and the charging head 106 is not energized, thereby protecting the equipment and operators and preventing accidental injuries.

The boxes 201 are sent out from the inside of the extension slot 102 one by one and spliced, so that after the multiple boxes 201 are spliced, the hinged plates 203 and the telescopic magnetic plates 204 on both sides are unfolded, so as to protect the vehicle from rain and sun, and realize the heat dissipation inside the charging pile 1. After the structural transformation, a sunshade and rainproof roof can be formed after extending from the inside of the extension slot 102 to protect the vehicle. A solar panel 202 is fixedly installed on the top of the box 201. In sunny weather, the solar panel 202 can fully utilize light energy to generate electricity;

The electric cylinder 313 drives the fixed plate 314 to move the lifting plates 301 on both sides back and forth, and then the limiting plates 302 inside the lifting plates 301 clamp the sides of the bottom of the hinge plates 203 on both sides of the box body 201, so that the lower box bodies 201 are lifted up one by one. When the lifting plate 301 moves up, the squeezing block 303 outside the lifting plate 301 squeezes the arc-shaped protrusion 307 at the bottom of the inner side of the support plate 304, so that the support plate 304 and the lifting plate 301 are lifted up. The limit bar 305 moves inwards. When the top of the hinge plate 203 contacts the limit bar 305 above, the limit bar 305 moves outwards. Then, when the box 201 moves to the top of the limit bar 305, the limit bar 305 extends again under the support of the support spring 306 and snaps into the bottom of the hinge plate 203 to support the box 201 that moves up, so that the boxes 201 move one by one to the highest position, and then the boxes 201 are sent out one by one through the push plate 311.

By utilizing the magnetism of the outer end of the docking plate 208, when the docking plate 208 moves to the tail of the previous box 201, the electromagnet 205 is energized to generate magnetic force, and the outer end of the docking plate 208 is magnetic, and a repulsive reaction is generated by the magnetism generated by the electromagnet 205, so that the docking plate 208 slides out from the inside of the installation slot 207 and is adsorbed to the inside of the docking slot 206 opened at the tail of the previous box 201, thereby achieving a fixed connection between the two boxes 201. At this time, the electromagnets 205 on both sides of the box 201 are energized to generate magnetism. When the box 201 is completely extended from the inside of the extension slot 102, the electromagnet 205 has a repulsive reaction to the telescopic magnetic plate 204. At this time, the telescopic magnetic plate 204 will expand horizontally and then slide from the inside of the hinged plate 203 to the outside.

When the box body 201 is retracted into the interior of the charging pile 1, the top box body 201 is supported by the limit plate 302 inside the lifting plate 301, and then the lifting plate 301 is moved down, bringing the functional module structure 2 down, and the arc-shaped protrusion 307 at the bottom inside the support plate 304 of the same height is squeezed by the extrusion block 303 outside the lifting plate 301, so that the limit bar 305 moves inward, so that the lifting plate 301 is lowered, and the functional module structure 2 is moved to the second limit bar 305 for placement, and then the first limit plate 302 at the top is energized and magnetically conductive, so that the first limit plate 302 at the top is adsorbed to the side of the lifting plate 301 and vertically upward. , when the first limiting plate 302 rises to the highest point again, the limiting plate 302 is powered off again, so that the first limiting plate 302 at the top receives the next functional module structure 2, and then the two functional module structures 2 inside are simultaneously moved down again. At this time, the squeezing block 303 squeezes the support plate 304 at the same height, so that the limiting bar 305 moves inward, and then the functional module structure 2 is moved down and placed on the limiting bar 305 below. When moving up again, the two limiting plates 302 at the top need to be powered on, so that the lifting plate 301 moves up, and so on, so that the external functional module structures 2 are moved one by one to the inside of the charging pile 1;

The second motor 412 at the top of the docking terminal 406 is used to drive the driving gear 413 and the rack 414 to mesh with each other, thereby driving the docking terminal 406 to move outside the power-on bottom plate 401, and then the function is selected through the control box 105, and then the docking terminal 406 is driven by the second motor 412 to move to the specified position and then dock and communicate with the power-on hole 402 on the power-on bottom plate 401, so as to dock with different modules and dock according to different requirements and different functional module structures 2, thereby achieving wider applicability and flexibility;

When the second motor 412 is used to drive the docking terminal 406 to move to the specified position, the limiting balls 409 arranged inside the sliding plates 407 on both sides of the docking terminal 406 are elastically supported by the return springs 408 and are inserted into the positioning grooves 415 opened on the inner side of the limiting slide grooves 404, thereby realizing the precise positioning of the docking terminal 406. When the docking terminal 406 moves to the specified position, the power-on hole 402 is energized. Under the action of the electromagnetic suction, the power-on terminal 410 is sucked out from the inside of the docking terminal 406 and connected to the inside of the power-on hole 402, thereby realizing the power-on of the connecting wire 107. When the power-on terminal 410 is not docked with the power-on hole 402 and is located inside the docking terminal 406 due to the magnetic attraction of the magnetic ring 411, the connecting wire 107 is not energized and the charging head 106 is not energized, thereby protecting the equipment and operators and preventing accidental injuries.
