Description

In order to improve energy efficiency, photovoltaic power generation technology has gradually been introduced into charging pile equipment, forming a charging and storage combined system with self-power supply capability.

[0003] The solar panels of traditional photovoltaic charging piles are generally laid on a small area, making it difficult to meet high-power charging needs within a limited area. Some charging piles with large photovoltaic panels are usually fixed facilities, making it difficult to retract the panels when idle, which significantly increases the area occupied by the equipment, causing a waste of public space resources and making it more likely to cause structural damage risks due to exposure to complex environments.

[0004] As for the charging piles with foldable photovoltaic panels, most of them adopt circular or rectangular radial expansion structure. Although this kind of layout can realize the storage and folding of photovoltaic panels, in actual use, they are radially expanded around the charging pile.

[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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention provides a charging and storage combined electric vehicle charging pile device, including a charging pile body 1, a substrate 5, a photovoltaic panel folding assembly 7 and a driving assembly 8, wherein the charging pile body 1 adopts a rectangular column structure, and the outer shell is made of a metal material with strong weather resistance (such as stainless steel), and a charging gun 2 is arranged on the side of the charging pile body 1 for charging the electric vehicle. The interior of the charging pile body 1 is divided into a front cavity 3 and a rear cavity 4 by a partition, and a charging unit and an energy storage unit are arranged in the front cavity 3. The charging unit includes a power converter and a control circuit, which are used to convert the electric energy of the energy storage unit or the external power grid into a current suitable for charging the electric vehicle. The energy storage unit adopts a high-capacity lithium battery pack, which can store the electric energy generated by the photovoltaic panel folding assembly 7 and power the charging unit when needed.

[0022] The base plate 5 is fixedly arranged on the top of the charging pile body 1, and a plurality of display panels 6 which are sequentially connected are arranged in the base plate 5, such as Figure 5 , Figure 8 and Fig. 9 As shown, it is arranged in a manner similar to the telescopic rod sleeve. The external display panel 6 is sleeved on the outside of the internal display panel 6, and finally slidably sleeved inside the base plate 5 (that is, the cross-section of the multiple display panels 6 after contraction is a plurality of concentric rectangles). A limiter is provided at the tail of each display panel 6 to prevent it from falling out. Each display panel 6 is arranged as a rectangular structure to expand the contact area between adjacent display panels 6, thereby reducing the pressure at the contact position of adjacent display panels 6 when the display panels 6 are unfolded. In particular, when the photovoltaic panel folding assembly 7 is arranged on the display panel 6, the photovoltaic panel folding assembly 7 needs to be connected to the display panel 6 with the largest possible contact area, so as to avoid excessive pressure on the local position of the display panel 6. Therefore, a large-area rectangular display panel 6 is provided to receive this pressure load, which can avoid excessive pressure in the contact area between adjacent display panels 6.

[0023] The plurality of display panels 6 can slide linearly in the same direction to be extended and retracted. When the display panels 6 are fully extended, the total length thereof is a multiple of the length of the base plate 5. When the display panels 6 are retracted, the plurality of display panels 6 are overlapped and stored inside the base plate 5.

[0024] Specifically, the width and length of the display panel 6 can be arranged according to the actual application scenario. Through the design of the width and length, the unfolded display panel 6 can cover the top area of ​​the car and simultaneously achieve the effect of shading the car from the sun and rain.

[0025] The photovoltaic panel folding assembly 7 is composed of multiple photovoltaic panels connected by hinges. The fixed side of the photovoltaic panel folding assembly 7 is fixed to the base plate 5 by bolts, and the movable side of the photovoltaic panel folding assembly 7 is fixedly connected to the end of the display panel 6 located in the center inner layer of the base plate 5 (that is, the display panel 6 located in the center inner layer of the multi-layer sleeved display panel 6 is equivalent to the head rod body of the telescopic rod in the prior art) through a connecting piece. The photovoltaic panel folding assembly 7 is folded in the initial state. When the display panel 6 is extended, the display panel 6 located in the innermost center layer slides outward, pulling the photovoltaic panel folding assembly 7 to unfold in a straight line direction to form a large area of ​​photovoltaic power generation surface. When the display panel 6 is retracted, the photovoltaic panel folding assembly 7 is folded back to the initial state.

[0026] Among them, for the setting of photovoltaic panels, although photovoltaic panels can be directly embedded on the surface of the display board 6, so that the photovoltaic panels are directly exposed when the display board 6 is extended or retracted. However, this method requires a more precise electrical connection process. Multiple photovoltaic panels need to be connected in series with wiring harnesses, and the entire panel needs to be connected to the energy storage unit with a separate wiring harness. And the display board 6 during movement may also cause damage to the connecting elements. Therefore, in this embodiment, a separate photovoltaic panel folding assembly 7 is provided on the display board 6, so that the stability of the photovoltaic panel folding assembly 7 during movement is higher. The photovoltaic panel folding assembly 7 as a whole can be electrically connected to the energy storage unit through a wiring harness, and this wiring harness is buried in a channel in the shell wall of the charging pile body 1, so that the wiring harness arrangement is more orderly.

[0027] In addition, the driving assembly 8 is disposed in the rear cavity 4 , and the driving assembly 8 is connected to the display board 6 . The driving assembly 8 is used to drive the display board 6 to directionally extend and retract to drive the photovoltaic panel folding assembly 7 to expand and retract.

[0028] In specific applications, the user drives the electric car to the front of the charging pile body 1, and then drives the display panel 6 to extend in the direction of the long axis of the car through the driving component 8, driving the photovoltaic panel folding component 7 to unfold, thereby achieving light energy conversion at the top of the electric car. Embodiment 2

[0029] On the basis of the first embodiment, this embodiment adds telescopic ground rails 9 on both sides of the bottom of the charging pile body 1 to increase the stability of the device during use. Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a vehicle parking area is formed between the telescopic ground rails 9 on both sides, making the parking charging operation more standardized and the area use more clear. The tail end of the telescopic ground rail 9 is fixedly set in the charging pile body 1, and the head end of the telescopic ground rail 9 is provided with a support rod 10, which extends vertically upward and is connected to the display board 6. Specifically, the support rod 10 is connected to the end of the display board 6 at the center of the substrate 5. The telescopic action of the telescopic ground rail 9 is synchronized with the telescopic action of the display board 6. When the drive assembly 8 drives the display board 6 to unfold, the display board 6 pulls the telescopic ground rail 9 to extend outward through the support rod 10 to form a stable support structure. When the display board 6 shrinks, the telescopic ground rail 9 retracts to the bottom of the charging pile body 1, and the support rod 10 is set on both sides of the charging pile body 1. The support rod 10 not only plays a supporting role, but also disperses the force when the photovoltaic panel folding assembly 7 is unfolded to ensure the overall stability of the equipment.

[0030] Further, such as Figure 3 As shown, the telescopic ground rail 9 includes a plurality of monorails 11 that are mutually sleeved, and the top surfaces or side surfaces of adjacent monorails 11 are slidably connected through a mosaic structure, and the mosaic structure can be a slide rail groove structure, so that the adjacent monorails 11 are slidably connected. Balls 12 are arranged on the bottom surface of the monorail 11 for rolling, and the balls 12 on the plurality of monorails 11 are located at the same horizontal height to contact the ground. The arrangement of the balls 12 is used to change the sliding friction into rolling friction to reduce the friction between the monorail 11 and the ground. In addition, the plurality of balls 12 are located at the same horizontal height so that the gravity of the photovoltaic panel folding assembly 7 is borne by the balls 12, and will not be applied to the mosaic structure of the monorail 11, thereby improving the stability of the structure in use. Embodiment 3

[0031] In the prior art, there are many types of driving components 8 for driving the multiple sleeved display panels 6 to unfold. For example, telescopic rods are arranged on both sides of the display panel 6, and the telescopic rods are connected to the two sides of the display panel 6 and extend and retract to achieve the synchronous extension and retraction function of the display panel 6. Alternatively, a telescopic rod is arranged at the bottom of the display panel 6, and the rod body is connected to the middle of the display panel 6 to achieve the purpose of driving the display panel 6 to extend and retract. However, since the display panel 6 in the device has a certain width, the above-mentioned prior art has problems such as large power output, low motion synchronization, and unstable motion when driving the display panel 6 to unfold in a driving mode close to point contact.

[0032] Therefore, based on the first embodiment, this embodiment provides a preferred specific structure of the driving assembly 8, such as Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, it includes a power output unit 13, a flexible push plate 14 and a bending track 15. The power output unit 13 is arranged in the rear cavity 4, the output side of the power output unit 13 is connected to the flexible push plate 14, and the flexible push plate 14 is slidably arranged in the bending track 15.

[0033] like Figure 5 As shown ( Figure 4 and Figure 5 The flexible push plate 14 is not shown in the bending groove 19 and the connecting groove 16 in the figure), the interior of the exhibition board 6 located in the central inner layer of the base plate 5 is hollow to form a connecting groove 16 (that is, in the structure of multiple sleeved exhibition boards 6, the exhibition board 6 located in the innermost center layer is hollowed out and has an opening toward the flexible push plate 14 to form a connecting groove 16, and the flexible push plate 14 is inserted into the connecting groove 16 through the opening and fixedly connected to this exhibition board 6), the connecting groove 16 is docked with the bending track 15 (in this embodiment, each exhibition board 6 and the tail of the base plate 5 are provided with an opening for the flexible push plate 14 to be inserted into the connecting groove 16 from the rear cavity 4), the head end of the flexible push plate 14 is arranged in the connecting groove 16 and is fully connected to the inner side surface of the end of the exhibition board 6, so that the exhibition board 6 located in the central inner layer becomes the head-driven exhibition board 6 that drives the entire exhibition board 6 to extend and retract.

[0034] When this embodiment is used, the flexible push plate 14 is fully connected to the inner side surface of the end of the internal display board 6 (that is, the end of the flexible push plate 14 is in contact with the inner wall surface of the display board 6), so that when the flexible push plate 14 is pushed forward, the pushing force applied to the end of the display board 6 is more uniform, so that the display board 6 can maintain parallel extension and retraction when extending or retracting, making the movement of the display board 6 more synchronized and not tilted.

[0035] Among them, Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the power output unit 13 can be meshed with the surface of the flexible push plate 14 through a tooth-tooth structure, thereby pushing the flexible push plate 14 to slide. The flexible push plate 14 can also be pushed to slide by friction force through friction contact. The bending track 15 is set on the inner wall of the rear cavity 4, and the flexible push plate 14 is slidably connected inside it. The bending track 15 can be set as a groove structure with a concave cross section, which plays a certain role in limiting the flexible push plate 14.

[0036] Furthermore, when a photovoltaic panel folding assembly 7 with a larger area needs to be formed, the extended length of the display panel 6 will be longer, and the internal space of the charging pile body 1 is limited. Therefore, by providing a flexible soft push plate 14 and a bending track 15 with a preset trajectory, a longer extension distance of the display panel 6 can be formed in the rear cavity 4 with limited space.

[0037] Specifically, Figure 2 , Figure 6 and Figure 7 As shown, the bending track 15 includes a cavity groove 17, an extension groove 18 and a bending groove 19 (such as Figure 5As shown in the figure, the cavity groove 17 is arranged at the bottom of the rear cavity 4, and a reel 20 is rotatably arranged in the cavity groove 17. The reel 20 is rotatably arranged on the cavity wall of the rear cavity 4, and the soft push plate 14 is curled on the reel 20. The reel 20 can be a reel 20 with certain damping and self-locking capabilities in the prior art. The extension groove 18 is arranged in the vertical side wall of the rear cavity 4, and the bending groove 19 is arranged at the top of the rear cavity 4. The two ends of the bending groove 19 are respectively connected to the extension groove 18 and the connecting groove 16.

[0038] The soft push plate 14 in this embodiment can be made of a material with a certain degree of flexible deformation ability (such as rubber), and is provided with frosted grains or tooth grooves for connecting with the power output unit 13. Embodiment 4

[0039] On the basis of the third embodiment, this embodiment adds a progressive cam structure inside the display board 6 to improve the sliding stability of the soft push plate 14 during the pushing process and to improve the load-bearing capacity of the entire display board 6 when it is unfolded.

[0040] like Figure 8 As shown, specifically, since the display board 6 structure inside the base plate 5 is a plurality of plate bodies connected together, and the display board 6 located in the central inner layer is connected to the flexible push plate 14 to form a head-driven display board 6 that drives the entire display board 6 to extend and retract, when the flexible push plate 14 pushes the entire display board 6 structure to extend, due to the existence of the wall thickness of the display board 6, there is a gap between the part of the flexible push plate 14 located in the outer display board 6 (the reference is the inner layer display board 6) and the inner wall of the outer display board 6. This gap may cause the flexible push plate 14 to bend during the advancement process, thereby reducing the extension and retraction stability of the display board 6 or even making it impossible to extend and retract.

[0041] Therefore, in order to solve the above problem, this embodiment provides mutually cooperating progressive cam structures on two adjacent display boards 6, and the progressive cam structures are used to clamp and abut the soft push plates 14 inside the display boards 6 when the display boards 6 are extended one by one.

[0042] like Figure 8 As shown, the progressive cam structure includes a driving part 28 disposed on the outer surface of the inner display board 6 and a clamping part 29 disposed on the inner surface of the outer display board 6. When the display board 6 slides outward and unfolds, the driving part 28 drives the clamping part 29 to flip toward the soft push board 14 to clamp and abut the soft push board 14. The clamping part 29 extends toward the soft push board 14, thereby reducing the gap between the soft push board 14 and the inner wall of the outer display board 6 (the reference object is the centermost display board 6), reducing its range of motion, and thus preventing its bending.

[0043] like Figure 8 and Fig. 9As shown, the progressive cam structure is arranged on each display board 6, that is, except for the driving portion 28 independently arranged on the outer wall of the center display board 6 and the clamping portion 29 independently arranged on the inner wall of the base plate 5, the clamping portions 29 and the driving portions 28 are respectively arranged on the inner walls and outer walls of the other display boards 6, so as to cooperate with the adjacent display boards 6.

[0044] Further, such as Fig. 9 As shown ( Fig. 9 The position where the limiting protrusion 33 rotates to protrude from the transverse groove 30 is not shown). This embodiment also provides a specific structure of a clamping part 29 and a driving part 28. This structure can immediately trigger the extension of the structure once the preset position is reached during the continuous movement of a single display board 6, so that the clamping part 29 limits the soft push plate 14 in a hierarchical progressive manner, which is more maneuverable. There is no need to wait for a single display board 6 to be fully extended to a position before being limited, thereby further reducing the possibility of bending of the soft push plate 14 during the sliding process and improving the stability of the driving process.

[0045] Specifically, the clamping portion 29 includes a plurality of transverse grooves 30 in a linear array on the inner wall of the display board 6 , the length direction of the transverse grooves 30 is perpendicular to the direction of extension and contraction of the display board 6 , and the linear arrangement direction of the plurality of transverse grooves 30 is parallel to the direction of extension and contraction of the display board 6 .

[0046] The opening of the transverse groove 30 is arranged toward the flexible push plate 14, and an optical axis 32 is rotatably arranged in the transverse groove 30, and a limiting protrusion 33 is arranged on the optical axis 32. The limiting protrusion 33 can be integrally arranged on the outer wall of the optical axis 32. When the optical axis 32 rotates axially, the limiting protrusion 33 can rotate to a position protruding from the opening of the transverse groove 30 along with the rotation of the optical axis 32, thereby contacting the surface of the flexible push plate 14. The limiting protrusion 33 is arranged in the transverse groove 30 in a horizontal posture under normal conditions. When the optical axis 32 rotates 90 degrees, the limiting protrusion 33 protrudes from the opening of the transverse groove 30.

[0047] like Fig. 9 and Fig.10 As shown, the ends of the optical axis 32 are coaxially fixed with end gears 34, which are meshed with a reversing gear 35. The reversing gear 35 is used for redirection, ensuring that when the soft push plate 14 extends outward, the optical axis 32 is driven to rotate. The reversing gear 35 is meshed with a driving gear 36, and the edge of the driving gear 36 protrudes from the transverse groove 30. Fig. 9 As shown, the end gear 34, the reversing gear 35 and the driving gear 36 are arranged sequentially in the extending direction of the display board 6. This arrangement can ensure that the limit protrusion 33 is rotated out after the soft push plate 14 passes the driving gear 36, so that the rotated limit protrusion 33 will not abut against the outer wall of the display board 6, ensuring that the rotated limit protrusion 33 must be in contact with the soft push plate 14, so that the limit function can be carried out normally.

[0048] The driving part 28 includes longitudinal grooves 37 provided on both sides of the outer wall of the inner display panel 6. The longitudinal grooves 37 are aligned with the driving gear 36 to avoid the driving gear 36, and the tail position of the longitudinal grooves 37 is provided with engaging teeth 38 for cooperating with the driving gear 36, which is used to drive the driving gear 36 to rotate through the engaging teeth 38 when passing the driving gear 36, thereby driving the limiting protrusion 33 to rotate. Synchronous grooves are provided on both sides of the soft push plate 14, which are not shown in the figure. The synchronous grooves are aligned with the driving gear 36 to avoid the driving gear 36.

[0049] In this embodiment, the progressive support of the plurality of limiting protrusions 33 driven by the plurality of optical axes 32 not only reduces the range of motion of the flexible push plate 14 and prevents it from bending in the display board 6 , but also improves the overall load-bearing capacity of the display board 6 .

[0050] In actual use, the gravity of the photovoltaic panel folding assembly 7 with a large area is relatively large. After the display panel 6 is extended, the contact area between the ends of adjacent display panels 6 is relatively small, so this position will have a relatively large pressure bearing capacity, which is not conducive to the stable use of the overall device during a long period of charging. By using multiple limiting protrusions 33 to fill the gap between the inner wall of the display panel 6 and the soft push plate 14, there are more contact points and a larger contact area between adjacent display panels 6. The unfolded display panel 6 structure can be similar to a whole plate structure, and the local pressure is reduced by dispersing the pressure, thereby improving the load-bearing capacity and use strength of the overall structure.

[0051] In addition, when the flexible push plate 14 is connected to the power output unit 13 through the tooth groove structure, in order to prevent the rotating protruding limiting protrusion 33 from being embedded in the tooth groove on the bottom surface of the flexible push plate 14 when sliding, there are many ways to avoid this in actual production. For example, the width of the tooth groove on the flexible push plate 14 can be shortened or the width of the limiting protrusion 33 can be enlarged so that the two cannot fit together, thereby preventing the limiting protrusion 33 from being stuck in the tooth groove. Alternatively, only one-sided limiting protrusion 33 is provided, that is, a clamping portion 29 is provided on the upper inner wall of the display board 6, and no clamping portion 29 is provided on the lower inner wall, thereby avoiding the limiting protrusion 33 from being stuck with the tooth groove.

[0052] Further, such as Fig. 9As shown, in this embodiment, in order to prevent the continuous sliding soft push plate 14 from rubbing against the limiting protrusion 33 and to overwhelm the already protruding vertical limiting protrusion 33, this embodiment further provides a flexible deformation stopper 39 fixedly disposed at the opening of the transverse groove 30, and a limiting groove 31 is disposed in the middle of the flexible deformation stopper 39, and the limiting groove 31 is configured to match the shape of the limiting protrusion 33. By providing a layer of flexible deformation stopper 39 outside the limiting protrusion 33, when the limiting protrusion 33 rotates to the vertical state, it can reduce the friction between the two by squeezing the flexible deformation stopper 39, and the flexible deformation stopper 39 with a smooth surface contacts the soft push plate 14, thereby reducing the possibility of driving the limiting protrusion 33 to rotate continuously. Furthermore, a limiting groove 31 is provided in the middle of the flexible deformation stopper 39. When the limiting protrusion 33 rotates to a vertical state, its head end is embedded in the limiting groove 31, and the limiting protrusion 33 is limited to continue to rotate and fall through the steps on both sides of the limiting groove 31. In addition, the head end of the limiting protrusion 33 can be set as a rotating roller to change the sliding friction into rolling friction to reduce the friction force, so as to avoid the limiting protrusion 33 in a vertical state being driven to a horizontal state due to excessive friction when the soft push plate 14 continues to rotate, thereby failing to limit the soft push plate 14. Alternatively, the resistance of the rotation connection of the driving gear 36, the reversing gear 35 or the optical axis 32 is increased, so that the optical axis 32 can only be rotated by the larger engagement force when the engagement teeth 38 are engaged with the driving gear 36, which can also avoid the friction push of the limiting protrusion 33 during the sliding process of the soft push plate 14. Embodiment 5

[0053] Based on the third embodiment, this embodiment combines the motion trajectory of pulling out the charging gun 2 with the action of driving the display board 6 to unfold, so that the user can unfold the display board 6 after unplugging the charging gun 2 and moving it linearly outward for a certain distance, thereby reducing the operating steps of the device and improving the use efficiency of the device.

[0054] Specifically, Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the power output unit 13 includes a long-axis gear 21 meshingly connected to the surface of the flexible push plate 14, the long-axis gear 21 is rotatably installed in the rear cavity 4 through a rotating shaft, a bevel gear plate 22 is coaxially fixed on the rotating shaft, the bevel gear plate 22 is meshingly connected with a bevel gear column 23, the bevel gear column 23 is fixedly installed on the inner wall of the rear cavity 4 through a mounting bracket 24, the bevel gear column 23 is meshingly connected with a driving gear plate 25, the driving gear plate 25 is slidably set in a linear rail plate 26, the linear rail plate 26 is fixedly installed in the rear cavity 4, the linear rail plate 26 penetrates the charging pile body 1 and extends outward, and the linear rail plate 26 is arranged below the charging port on the side wall of the charging pile body 1.

[0055] like Figure 7 As shown, a charging gun 2 is movably connected to the charging port, an engaging slider 27 is fixedly connected to the bottom of the charging gun 2, and the engaging slider 27 is movably engaged with the driving gear plate 25.

[0056] Among them, when the charging port on the charging pile body 1 is connected to the charging gun 2, the charging gun 2 is locked by the built-in locking mechanism. When the user unlocks it through the mobile phone and pulls out the charging gun 2, the meshing slider 27 slides on the linear track, and at this time the meshing slider 27 is meshed and connected with the driving gear plate 25, so that the driving gear plate 25 can be driven to move linearly, and then the long shaft gear 21 is driven to rotate, and the display board 6 is extended. The purpose of labor saving can be achieved by the tooth ratio in the power output unit 13. It is also possible to add a multiple-range gear structure in the prior art so that the sliding stroke of the display board 6 is twice or even multiple times the stroke of the meshing slider 27, thereby achieving the purpose of reducing the moving distance of the charging gun 2.

[0057] Further, such as Figure 1 As shown, the portion of the linear rail plate 26 located outside the charging pile body 1 is rotated and folded by a rotating structure and arranged on one side of the charging pile body 1, so that the linear rail plate 26 can be folded and stored when idle, and will not take up too much space. The rotating structure may be a rotating component with a position fixing function, such as a ratchet structure. In this embodiment, the drive tooth plate 25 may be arranged as an integral one-stage structure. At this time, when the linear rail plate 26 is rotated and folded downward, the shorter section of the drive tooth plate 25 located outside the charging pile body 1 is suspended and connected to the meshing slider 27. It may also have two sections, and the two sections of the drive tooth plate 25 are rotatably connected by a hinge, and the outer section is arranged in the linear rail plate 26 and folds with the linear rail plate 26.
