Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a DC charging pile integrating photovoltaic energy storage and charging in highway service areas. Background Technology

[0002] The integrated photovoltaic-energy storage-charging DC charging pile in highway service areas is a device that integrates photovoltaic power generation, energy storage and DC charging functions to meet the charging needs of new energy vehicles in service areas. At the same time, it reduces energy consumption through photovoltaic clean energy power generation and is suitable for the energy replenishment scenario of highway service areas.

[0003] However, existing photovoltaic panels in similar equipment are mostly fixed installation structures, lacking targeted wind protection designs. Under the influence of strong winds in severe weather, the large windward area of ​​the photovoltaic panels makes them prone to bending, cracking, or falling off, resulting in a shortened lifespan of the photovoltaic modules and increased equipment maintenance costs. Furthermore, some protective structures rely on electric drive triggering, which results in a delayed response and insufficient reliability in unattended service areas, making it difficult to quickly respond to sudden strong winds and effectively ensure the safety of the photovoltaic modules. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a DC charging pile that integrates photovoltaic, energy storage and charging in highway service areas. This solves the problems that the photovoltaic panels of existing DC charging piles that integrate photovoltaic, energy storage and charging in highway service areas lack wind protection and are easily damaged, have a short lifespan, and that some protective structures rely on electric drive, resulting in sluggish response and insufficient reliability.

[0024] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0025] Reference Figure 1-6 According to an embodiment of the present invention, a DC charging pile integrating photovoltaic, energy storage and charging in a highway service area includes: a charging pile housing 9, a support 7 fixedly connected to the upper surface of the charging pile housing 9, and a support plate 12 fixedly connected to the upper surface of the support 7.

[0026] Specifically: the charging pile housing 9 is the housing of the integrated energy storage and charging pile. The integrated energy storage and charging pile is an integrated energy supply device that integrates photovoltaic power generation, energy storage and DC charging functions, can store electrical energy and provide charging services for new energy vehicles on demand. This is an existing mature technology and is well known to people in this field, so it will not be elaborated in this article.

[0027] Considering the existing fixed installation of photovoltaic panels cannot be folded and is prone to damage due to its large windward area in strong winds, a folding component is provided on the upper surface of the support plate 12. This folding component guides the folding of the assembled photovoltaic panel components. The folding component includes: slider 1 (2), two sliders 2 (10), two sliders 3 (11), two transverse slide rails (3), two arc-shaped slide rails (4), and one longitudinal slide rail (5). Slider 1 (2) is fixed to the side of the middle connecting frame 18 among the three connecting frames 18; the two sliders 2 (10) are respectively fixed to the sides of the connecting frames 18 on both sides of the three connecting frames 18; and the two sliders 3 (11) are respectively fixed to the sides of the photovoltaic panels 13 on both sides of the four photovoltaic panels 13. The longitudinal slide rail 5 is located between the two transverse slide rails. Between rails 3, two arc-shaped slide rails 4 are located on opposite sides of the two transverse slide rails 3; slider 1 2 is slidably disposed in the longitudinal slide rail 5, two sliders 2 10 are slidably disposed in the two transverse slide rails 3, and two sliders 3 11 are slidably disposed in the two arc-shaped slide rails 4; by sliding slider 1 2 along the longitudinal slide rail 5, the two sliders 2 10 are driven to slide towards each other along the corresponding transverse slide rails 3 to drive the two photovoltaic panels 13 in the middle to fold. When the two photovoltaic panels 13 in the middle fold, the two photovoltaic panels 13 on both sides are driven to move towards the middle, so that the two sliders 3 11 slide downward along the corresponding arc-shaped slide rails 4, thereby driving the two photovoltaic panels 13 on both sides to fold, and finally forming an M-shaped folding state;

[0028] Slider 1 (2), slider 2 (10), and slider 3 (11) slide in conjunction with their respective slide rails. Through the linkage between the multiple sliders and the slide rails, the photovoltaic panel 13 is folded, enabling the photovoltaic panel 13 to quickly form an M-shaped compact structure, effectively reducing the windward area to avoid damage from strong winds.

[0029] Considering the inconvenience of folding and protecting a single photovoltaic panel simultaneously, a combined photovoltaic panel component is provided inside the folding component. The combined photovoltaic panel component includes: multiple connecting frames 18 and multiple photovoltaic panels 13. The three connecting frames 18 are evenly distributed among the four photovoltaic panels 13, and each connecting frame 18 is hinged to two adjacent photovoltaic panels 13.

[0030] Three connecting frames 18 are hinged to four photovoltaic panels 13 to form a combined structure. When folding, the force is transmitted through the connecting frames 18, so as to increase the power generation area while ensuring that the photovoltaic panels 13 fold smoothly and synchronously.

[0031] Considering that the folding action requires a reliable driving force and that the triggering process is prone to collision damage, a wind-triggered component is provided inside the support 7. This component is used to trigger the folding mechanism to fold and protect the combined photovoltaic panel components when the wind is strong. The wind-triggered component includes: a support rod 19 and a counterweight 14. The support rod 19 is fixedly connected to the lower surface of the middle connecting frame 18 among the three connecting frames 18. The counterweight 14 is fixedly connected to the lower end of the support rod 19. A through hole 20 is provided on the support plate 12, and the counterweight 14 is movably connected inside the through hole 20. A buffer pad 8 is fixedly connected to the upper surface of the charging pile housing 9, and the buffer pad 8 is movably connected to the counterweight 14.

[0032] The counterweight 14 is connected to the intermediate connecting frame 18 via the support rod 19. When it falls, it drives the connecting frame 18 to move down and triggers folding. The buffer pad 8 absorbs the impact force of the counterweight 14 falling, which not only provides power for folding, but also avoids structural collision damage.

[0033] Considering that the photovoltaic panels need to remain in the unfolded power generation state when there is no wind and need to be precisely unlocked and folded when there is strong wind, the wind triggering component also includes: multiple guide rails 27, multiple guide rails 27 are fixedly connected to the lower surface of the support plate 12 at equal intervals around the circumference, the guide rails 27 are slidably connected to the inside of the guide rails 27, and the guide rails 27 are movably connected to the counterweight block 14. The guide rails 26 are fixedly connected to the bottom surface of the guide rails 27 with a return spring 25.

[0034] The reset spring 25 normally pushes the locking block 26 to lock the counterweight block 14. When triggered by strong wind, the locking block 26 slides to unlock, ensuring that the photovoltaic panel 13 is stably unfolded when there is no wind and that the folding is accurately started when there is strong wind, avoiding accidental triggering that affects use.

[0035] Considering the need for precise wind-triggered folding and the need to avoid accidental triggering in a light breeze, the wind-triggered component also includes: multiple rotating rods 30, each with a windward plate 15 and a cam 24 fixedly connected to its sidewall; a crank 23 is hinged to the lower surface of the protrusion of the cam 24, and the other end of the crank 23 is hinged to the lower surface of the locking block 26; the rotation of the cam 24 can drive the locking block 26 to slide via the crank 23; a through hole 21 is provided on the windward plate 15, and a baffle 16 is rotatably connected inside the through hole 21; a stop block 17 is fixedly connected to the inner surface of the through hole 21 and is movably connected to the baffle 16 to restrict the baffle 16 to swing in only one direction; a limit plate 22 is fixedly connected to the lower surface of the support plate 12 and is movably connected to the windward plate 15 to restrict the windward plate 15 to swing in only one direction.

[0036] Strong wind drives the windward plate 15 to rotate the rotating rod 30 and cam 24, which in turn pulls the locking block 26 to slide through the crank 23. The one-way limiting structure restricts the windward plate 15 and the baffle 16 from swinging in the opposite direction, so as to achieve precise control that can be triggered quickly in any wind direction and will not move in a light breeze.

[0037] Considering that multiple wind-facing plates need to swing synchronously when a unidirectional wind is received, thereby triggering all the locking blocks, the wind triggering component also includes: multiple gears 29 and an internal gear ring 28. The multiple gears 29 are fixedly connected to the outer wall of multiple rotating rods 30 in a one-to-one correspondence. The internal gear ring 28 is sleeved on the outside of the multiple gears 29 and meshes with the multiple gears 29. The internal gear ring 28 passes through multiple wind-facing plates 15 in the transverse direction.

[0038] Gear 29 meshes with internal gear ring 28. The movement of any wind-facing plate 15 can drive all rotating rods 30 to rotate synchronously, ensuring that the wind force triggers synchronously and improving the stability and reliability of folding trigger.

[0039] In summary, the improvement of this embodiment lies in:

[0040] By linking wind-triggered and folding components, the photovoltaic panel 13 can automatically fold for protection in windy conditions. The purely mechanical triggering requires no electricity, has a rapid response, and can quickly reduce the windward area of ​​the photovoltaic panel 13, avoiding damage caused by strong winds. This significantly extends the service life of the photovoltaic module in severe weather and effectively reduces equipment maintenance costs.

[0041] Based on the above, other structures also need to be disclosed in detail, such as:

[0042] Considering the installation and fixing of multiple slide rails, the bottom of the two arc-shaped slide rails 4 and the longitudinal slide rail 5 are fixedly connected to a fixing seat 6, and the fixing seat 6 is fixedly connected to the upper surface of the support plate 12. A support frame 1 is fixedly connected between the two arc-shaped slide rails 4, the transverse slide rail 3 and the longitudinal slide rail 5.

[0043] The fixed base 6 fixes the bottom of the slide rail, and the support frame 1 connects each slide rail to form a stable frame, providing stable guidance for the slider to slide, ensuring a smooth and uninterrupted folding process, and extending the service life of the components.

[0044] Working principle: Under normal conditions, the photovoltaic panel 13 of the integrated photovoltaic-storage-charging DC charging pile in the highway service area is hinged and unfolded through the connecting frame 18. The locking block 26 locks the counterweight block 14 under the action of the reset spring 25 to ensure that the photovoltaic panel 13 stably receives sunlight and generates electricity. The electrical energy is stored through the integrated storage and charging structure or directly charges new energy vehicles.

[0045] When encountering strong winds, the strong wind drives the windward plate 15 to swing. Under the one-way limiting action of the baffle 16, the stop block 17 and the limiting plate 22, the windward plate 15 drives the rotating rod 30 to rotate. Through the meshing transmission of the gear 29 and the internal gear ring 28, all the rotating rods 30 are linked synchronously, which in turn drives the cam 24 to rotate. The cam 24 pulls the locking block 26 along the guide rail 27 through the crank 23 and compresses the return spring 25, releasing the lock on the counterweight block 14.

[0046] The counterweight 14 falls along the through hole 20, and the intermediate connecting frame 18 moves down through the support rod 19, triggering the slider 1 2 to slide along the longitudinal slide rail 5, which in turn drives the two sliders 2 10 on both sides to slide towards each other along the transverse slide rail 3, driving the two photovoltaic panels 13 in the middle to fold. When the middle photovoltaic panel 13 folds, it drives the two photovoltaic panels 13 on both sides to move closer to the middle, causing the slider 3 11 to slide down along the arc-shaped slide rail 4. Finally, the photovoltaic panel 13 folds to form an M-shaped compact structure.

[0047] During this process, the buffer pad 8 absorbs the impact force of the falling counterweight 14, the support frame 1 and the fixed seat 6 ensure the stability of the slide rail assembly, and ensure that the folding action is smooth and stable. Through pure mechanical linkage, the windward area of ​​the photovoltaic panel 13 is quickly reduced, realizing automatic protection in windy environments.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
