Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a charging pile and its usage method. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the number of electric vehicles continues to grow, and the demand for public and dedicated charging infrastructure is becoming increasingly urgent. Against the backdrop of scarce urban parking resources, traditional fixed charging piles, due to their long construction cycles, low space utilization, and poor scalability, are no longer able to meet the balance between dynamically changing charging demands and limited land resources.

[0003] Currently, most existing or under-construction parking lot charging stations are fixedly installed, meaning each charging station occupies an independent parking space or adjacent space, with an unchangeable structure and non-adjustable function. This design has the following significant drawbacks:

[0004] Large space occupation, affecting the parking of fuel vehicles: Traditional charging piles are mostly rigid structures that occupy parking areas for a long time, which is particularly prominent in small and medium-sized parking lots. Their fixed layout squeezes the already scarce parking space resources, resulting in a shortage of parking spaces for fuel vehicles, causing user dissatisfaction, and reducing the overall utilization efficiency and turnover rate of the parking lot.

[0005] Lack of flexibility and scalability: Existing charging stations cannot be flexibly adjusted according to changes in actual charging demand. If large-scale deployment is carried out in the initial stage according to long-term forecasts, it is easy to cause the phenomenon of "charging stations waiting for cars" to be idle; while if demand surges in the later stage, it will face problems such as difficulty in expansion and high cost of secondary construction.

[0006] Transportation and installation are inconvenient: Large integrated charging piles are bulky, occupy a lot of space during transportation, are complicated to load and unload, and have high transportation costs, which is not conducive to rapid deployment and promotion. Summary of the Invention

[0007] In view of this, the present invention proposes a charging pile and its usage method. By setting a folding mechanism, the charging capacity of the charging pile can be dynamically adjusted, which facilitates the transportation, installation and subsequent expansion of the charging pile.

[0008] The technical solution of the present invention is implemented as follows: On one hand, the present invention provides a charging pile, including multiple connecting frames, folding plates, connecting hinges, and two end plates, wherein the multiple connecting frames are arranged in parallel and spaced apart; the folding plates are rotatably disposed between two adjacent connecting frames via connecting hinges, and two folding plates are disposed between two adjacent connecting frames; the two end plates are respectively fixedly disposed on the connecting frames located at both ends; the folding plate includes a first enclosure plate and a second enclosure plate, both of which are rotatably disposed on the connecting frame via connecting hinges, and the first enclosure plate and the second enclosure plate are rotatably connected; when both the first enclosure plate and the second enclosure plate are perpendicular to the connecting frame, the first enclosure plate, the second enclosure plate, and the end plates enclose and form an installation cavity.

[0009] Based on the above technical solutions, preferably, when both the first and second enclosures abut against the connecting frame, the first and second enclosures within the same folding plate abut against each other.

[0010] Based on the above technical solutions, preferably, the connecting frame is a rectangular frame structure. When both the first and second side panels abut against the connecting frame, the first side panel in one folding panel and the second side panel in the other folding panel abut against each other and block the connecting frame.

[0011] Based on the above technical solutions, preferably, the second enclosure is provided with heat dissipation holes.

[0012] Based on the above technical solutions, preferably, when both the first enclosure and the second enclosure are perpendicular to the connecting frame, the outer sides of the first enclosure, the outer sides of the second enclosure, and the outer sides of the connecting frame are flush; the first enclosure and the second enclosure have the same dimensions, the length of the first enclosure is a, the width is b, and the length of the connecting frame is c, where c = 2a + 2b.

[0013] Based on the above technical solutions, preferably, the connecting hinge includes a first rotating plate, a second rotating plate, and a rotating shaft. The first rotating plate and the second rotating plate are respectively fixedly mounted on the folding plate and the connecting frame; the rotating shaft is fixedly mounted on the first rotating plate and rotatably connected to the second rotating plate.

[0014] Based on the above technical solutions, preferably, the connecting hinge further includes a collar, a first spring, and a first locking pin. The collar is fixedly mounted on the rotating shaft, and a locking groove is formed on the circumference of the collar. An installation groove is formed on the second rotating plate, and the first spring is disposed in the installation groove. The first locking pin is slidably disposed in the installation groove, with one end of the first locking pin abutting against the first spring and the other end engaging with the locking groove.

[0015] Based on the above technical solutions, preferably, the connecting hinge further includes a collar, a first spring, a first locking pin, a second spring, a second locking pin, and a friction ring. The collar is rotatably mounted on the rotating shaft, and four slots are formed on the circumference of the collar. The four slots are arranged in a circumferential array around the axis of the collar, and a positioning groove is formed inside the collar. An installation groove is formed on the second rotating plate, and the first spring is disposed in the installation groove. The first locking pin is slidably disposed in the installation groove, with one end abutting against the first spring and the other end engaging with the slot, and the end of the first locking pin engaging with the slot is wedge-shaped. An assembly groove is formed on the rotating shaft, and the second spring is disposed in the assembly groove. The second locking pin is slidably disposed in the assembly groove, with one end abutting against the second spring and the other end engaging with the positioning groove. The friction ring is fixedly mounted on the rotating shaft and frictionally engages with the collar.

[0016] Based on the above technical solutions, preferably, the collar is provided with an operating hole, one end of which is connected to the positioning groove, and the other end extends through to the periphery of the collar.

[0017] Secondly, the present invention provides a method for using the above-mentioned charging pile, comprising the following steps: S1, unfolding a corresponding number of the folding plates according to actual needs to form a required number of the mounting cavities; wherein, when the required number of mounting cavities is multiple, the unfolded folding plates are located between two of the mounting cavities, and the spacing between the multiple mounting cavities is adjusted by rotating the unfolded folding plates; S2, installing the power supply module in the mounting cavity and connecting it to the control unit and display unit on the end plate, and installing the charging gun on the folding plate and connecting it to the power supply module and control unit; S3, fixing the connecting frame on a preset mounting base, and sealing the opening above the mounting cavity with a cover plate.

[0018] The charging pile and its usage method of the present invention have the following advantages over the prior art:

[0019] (1) By setting up a folding plate, the charging pile can be folded and expanded, which not only facilitates the transportation and installation of the charging pile, but also enables the charging pile to be adapted to actual needs, thus improving the ease of use of the charging pile.

[0020] (2) By limiting the specifications of the first and second enclosures, the space occupied by the charging pile after folding can be reduced and the independence of the two installation cavities can be improved; by limiting the position of the side wall after unfolding and folding the folding plate, the utilization rate of the internal space of the charging pile can be further improved and the structural strength of the charging pile can be guaranteed.

[0021] (3) By setting a connecting hinge with a locking function, the structural strength of the charging pile can be further improved; by making the locking function of the connecting hinge related to the number of rotations, the connecting hinge is more adaptable to the folding and unfolding of the charging pile, thereby improving the installation efficiency of the charging pile.

[0036] The technical solutions of this invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] Under the premise that the overall area and functional layout of the parking lot remain unchanged, the construction and operation of charging piles should follow the principles of "demand-oriented, phased implementation, and dynamic optimization". In the initial stage, blindly adding a large number of charging piles may seem to be in response to the development trend of new energy vehicles, but it may actually cause resource misallocation: On the one hand, the current number of electric vehicles and the average daily charging demand are still in the process of increasing, and excessive construction ahead of schedule may lead to idle charging piles, increased operation and maintenance costs, and a longer investment return period; on the other hand, a large number of fixed charging piles will occupy the original parking space (especially in the absence of intelligent scheduling or shared parking space mechanisms), which will directly reduce the parking capacity of fuel vehicles, cause dissatisfaction among fuel vehicle users, and even affect the overall turnover efficiency and user experience of the parking lot.

[0038] The present invention provides a charging pile, which includes a connecting frame 1, a folding plate 2, a connecting hinge 3 and two end plates 4. The number of charging guns can be selected according to different usage scenarios and nodes, adapting to the needs of small and medium-sized parking lots and reducing investment and maintenance costs.

[0039] like Figure 1 and Figure 2 As shown, multiple connecting frames 1 are provided, and the multiple connecting frames 1 are arranged in parallel and spaced apart. The folding plate 2 is rotatably set between two adjacent connecting frames 1 through the connecting hinge 3, and two folding plates 2 are set between two adjacent connecting frames 1. Two end plates 4 are respectively fixedly set on the connecting frames 1 located at both ends. The folding plate 2 can be folded in half. When the folding plate 2 is unfolded, the folding plate 2 and the end plate 4 enclose and form an installation cavity 100. When the folding plate 2 is folded in half, the installation cavity 100 disappears, thereby reducing the overall space occupied by the charging pile.

[0040] The mounting cavity 100 is used to install the power supply module and the charging gun head, and its number represents the actual number of vehicles that the charging pile can charge. The connecting frame 1 is preferably set to 4-6, and one charging gun head can be set on each folding plate 2, that is, the charging pile can charge 2-10 vehicles at the same time.

[0041] During transportation, all folding panels 2 are folded to minimize the space occupied by the charging pile, improve the transportation convenience of the charging pile, and reduce the transportation cost of the charging pile. When the charging pile is put into use in small and medium-sized parking lots, one pair of folding panels 2 are unfolded first to form an installation cavity 100. As the demand increases in the future, the remaining folding panels 2 are gradually unfolded to meet the actual needs.

[0042] like Figure 3 As shown, when two mounting cavities 100 are required, it is preferable to unfold the folding plate 2 located at both ends of the charging pile, that is, the two mounting cavities 100 are located at both ends of the charging pile, and the folding plate 2 after being folded is located between the two mounting cavities 100. At this time, the distance between the two mounting cavities 100 can be adjusted by rotating the folding plate 2 after being folded, so as to meet different usage requirements.

[0043] like Figure 4 As shown, the folding panel 2 includes a first enclosure 21 and a second enclosure 22. Both the first enclosure 21 and the second enclosure 22 are rotatably mounted on the connecting frame 1 via connecting hinges 3, and the first enclosure 21 and the second enclosure 22 are rotatably connected by hinges or other means. Figure 2 As shown, when the first enclosure 21 and the second enclosure 22 are both perpendicular to the connecting frame 1, the first enclosure 21, the second enclosure 22 and the end plate 4 enclose and form the mounting cavity 100. When the first enclosure 21 and the second enclosure 22 are both parallel to the connecting frame 1, the folding plate 2 is folded in half.

[0044] like Figure 2 As shown, when both the first enclosure 21 and the second enclosure 22 are parallel to the connecting frame 1, it is preferable that both the first enclosure 21 and the second enclosure 22 abut against the connecting frame 1, thereby effectively reducing the overall space occupied by the charging pile in the folded state; similarly, when both the first enclosure 21 and the second enclosure 22 abut against the connecting frame 1, it is preferable that the first enclosure 21 and the second enclosure 22 within the same folding plate 2 abut against each other.

[0045] Connecting frame 1 is a rectangular frame structure, that is, connecting frame 1 appears as a rectangular ring when viewed from the side, such as... Figure 5As shown, when the first enclosure 21 and the second enclosure 22 are both in contact with the connecting frame 1, the first enclosure 21 in one folding plate 2 and the second enclosure 22 in the other folding plate 2 opposite to it abut against each other and block the connecting frame 1. This structural design can, on the one hand, further reduce the overall space occupied by the charging pile in the folded state, and on the other hand, isolate the two adjacent mounting cavities 100 to realize the independent operation of the two adjacent mounting cavities 100.

[0046] The second enclosure 22 is provided with heat dissipation holes 201, which can dissipate the heat generated inside the charging pile during operation, thereby ensuring the normal use of the charging pile.

[0047] like Figure 2 and Figure 6 As shown, heat dissipation holes 201 are only opened in the second enclosure 22, and not on the first enclosure 21. The two folding plates 2 in the same mounting cavity 100 are arranged in a centrally symmetrical manner. When the first enclosure 21 and the second enclosure 22 in the same folding plate 2 abut together, the first enclosure 21 can block the heat dissipation holes 201 in the second enclosure 22, thereby preventing the heat dissipation holes 201 from affecting the independence between the two mounting cavities 100.

[0048] During operation, the charging pile relies on the heat dissipation holes 201 for heat dissipation, such as Figure 2 As shown, when the first enclosure 21 and the second enclosure 22 are both perpendicular to the connecting frame 1, the outer sides of the first enclosure 21, the outer sides of the second enclosure 22 and the outer sides of the connecting frame 1 should be flush to maximize the space of the mounting cavity 100.

[0049] When the first enclosure 21 and the second enclosure 22 are both in contact with the connecting frame 1, it is preferable to make the outer side of the first enclosure 21, the outer side of the second enclosure 22 and the outer side of the connecting frame 1 form a corrugated shape to further reduce the space occupied by the charging pile after folding. At the same time, the structure has stronger rigidity and impact resistance, better anti-vandalism performance, and can also achieve better heat dissipation effect.

[0050] like Figure 4 As shown, the first enclosure 21 and the second enclosure 22 have the same dimensions. The length of the first enclosure 21 is a, the width is b, and the length of the connecting frame 1 is c. Preferably, c = 2a + 2b to achieve the above effect.

[0051] The connecting hinge 3 serves to allow the first enclosure 21 and the second enclosure 22 to rotate on the connecting frame 1, such as... Figure 2 and Figure 7As shown, the connecting hinge 3 includes a first rotating plate 31, a second rotating plate 32, and a rotating shaft 33. The first rotating plate 31 and the second rotating plate 32 are respectively fixedly mounted on the folding plate 2 and the connecting frame 1. The rotating shaft 33 is fixedly mounted on the first rotating plate 31 and rotatably connected to the second rotating plate 32, thereby realizing the rotation of the connecting frame 1 and the folding plate 2.

[0052] When the first enclosure 21 and the second enclosure 22 are combined to form the mounting cavity 100, in order to make the structure of the charging pile more robust, it is preferable to make the connecting hinge 3 have a locking function. When the connecting hinge 3 is in the unfolded state of the folding plate 2, the connecting hinge 3 can be locked and fixed.

[0053] In a preferred embodiment, the connecting hinge 3 further includes a collar 34, a first spring 35, and a first locking pin 36. The collar 34 is fixedly mounted on the rotating shaft 33, and a locking groove 301 is provided on the periphery of the collar 34. A mounting groove 302 is provided on the second rotating plate 32. The first spring 35 is disposed in the mounting groove 302, and the first locking pin 36 is slidably disposed in the mounting groove 302. One end of the first locking pin 36 abuts against the first spring 35. When the folding plate 2 drives the first rotating plate 31 to rotate to a designated position, the end of the first locking pin 36 away from the first spring 35 engages with the locking groove 301, thereby achieving the locking function.

[0054] This structure enables the self-locking function of the connecting hinge 3. Each time the folding plate 2 is unfolded, the connecting hinge 3 will trigger the self-locking mechanism. It is suitable for installation within the mounting cavity 100 located at the end of the charging pile. Figure 1 The mounting cavity 100 shown and Figure 4 The mounting cavity 100 on the right side is shown. However, the folding plate 2 located in the middle needs to be rotated back and forth two or more times during the use of the charging pile in order to install the power supply module into the mounting cavity 100. If the above-mentioned structure that triggers locking with one rotation is adopted, it will affect the rapid installation of the charging pile.

[0055] Therefore, this invention proposes a connecting hinge 3 that triggers the locking function only after multiple reciprocating rotations. Unlike the connecting hinge 3 described above, this connecting hinge 3 further includes a collar 34, a first spring 35, a first locking pin 36, a second spring 37, a second locking pin 38, and a friction ring 39. The collar 34 is rotatably mounted on a rotating shaft 33. Four slots 301 are formed on the circumference of the collar 34, arranged in a circumferential array around the axis of the collar 34. A positioning groove 303 is formed inside the collar 34. An installation groove 302 is formed on the second rotating plate 32. The first spring 35 is... Inside the mounting groove 302, the first locking pin 36 is slidably disposed within the mounting groove 302. One end of the first locking pin 36 abuts against the first spring 35, and the other end engages with the locking groove 301. The end of the first locking pin 36 that engages with the locking groove 301 is wedge-shaped. An assembly groove 304 is provided on the rotating shaft 33. The second spring 37 is disposed within the assembly groove 304. The second locking pin 38 is slidably disposed within the assembly groove 304. One end of the second locking pin 38 abuts against the second spring 37, and the other end engages with the positioning groove 303. The friction ring 39 is fixedly disposed on the rotating shaft 33 and engages with the collar 34 in frictional cooperation.

[0056] The charging pile is in a folded state after processing and during transportation. This state is also the initial state for connecting hinge 3. Figure 8 As shown, at this time, the first rotating plate 31 and the second rotating plate 32 are attached together, and the first locking pin 36 is engaged in one of the slots 301.

[0057] like Figures 8-9 As shown, when the folding plate 2 is unfolded, the folding plate 2 drives the first rotating plate 31 and the rotating shaft 33 to rotate 90 degrees clockwise, so that the connecting hinge 3 is in the unfolded state. The friction between the friction ring 39 on the rotating shaft 33 and the collar 34 drives the collar 34 to rotate 90 degrees clockwise, thereby causing the first locking pin 36 to engage with the next locking slot 301.

[0058] like Figures 9-10 As shown, when the folding plate 2 is folded again, the folding plate 2 drives the first rotating plate 31 and the rotating shaft 33 to rotate 90 degrees counterclockwise, so that the connecting hinge 3 is in the folded state. During this operation, the first locking pin 36 engages with the locking groove 301. The engagement force between the two is greater than the friction force between the friction ring 39 and the collar 34. Therefore, the collar 34 does not rotate. At this time, the positioning groove 303 is in the upper position, and the second locking pin 38 also rotates to the upper position, so that the second locking pin 38 engages with the positioning groove 303.

[0059] like Figures 10-11 As shown, when the folding plate 2 unfolds again, it drives the first rotating plate 31 and the rotating shaft 33 to rotate 90 degrees clockwise. Since the second locking pin 38 engages with the positioning groove 303, it also drives the collar 34 to rotate 90 degrees clockwise, allowing the first locking pin 36 to engage with the next locking groove 301. Figure 2 As shown, when the folding plate 2 is unfolded, the left end of the lower left first panel 21 abuts against the connecting frame 1. Therefore, the first rotating plate 31 cannot rotate clockwise. Figure 11 As shown, the engagement of the first locking pin 36 with the locking groove 301 prevents the collar 34 from rotating counterclockwise, while the engagement of the second locking pin 38 with the positioning groove 303 fixes the collar 34 to the rotating shaft 33, and the rotating shaft 33 is fixedly connected to the first rotating plate 31. Therefore, the first rotating plate 31 cannot rotate counterclockwise, thereby locking and fixing the first rotating plate 31, and keeping the connecting hinge 3 in a locked state.

[0060] To prevent accidental operation and allow the locked hinge 3 to return to its rotating state, an operating hole 305 is provided on the collar 34, such as... Figure 9 As shown, one end of the operating hole 305 is connected to the positioning groove 303, and the other end extends to the circumference of the collar 34. When the wire is inserted into the operating hole 305, the second locking pin 38 can slide out of the positioning groove 303. Then, by rotating the first rotating plate 31, the locked connecting hinge 3 can be restored to its rotating state.

[0061] The method of using a charging pile according to the present invention is as follows:

[0062] S1. According to actual needs, unfold the corresponding number of folding plates 2 to form the required number of mounting cavities 100. When there are multiple mounting cavities 100, the unfolded folding plate 2 is located between two mounting cavities 100. By rotating the unfolded folding plate 2, the spacing between multiple mounting cavities 100 can be adjusted so that the number and position of the mounting cavities 100 can be adapted to the actual working conditions.

[0063] S2, install the power supply module in the mounting cavity 100 and connect it to the control unit and display unit on the end plate 4, and install the charging gun on the folding plate 2 and connect it to the power supply module and control unit.

[0064] S3, fix the connecting bracket 1 on the preset mounting base, and use the cover plate to seal the opening above the mounting cavity 100; the opening below the mounting cavity 100 can be sealed by the preset base or sealing strip.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
