With the rapid development of new energy vehicles in my country, charging has become the primary problem to be solved by new energy vehicles. For example, the number of charging piles installed in many cities is small and the mobility is poor. Therefore, there is an urgent need to provide a foldable photovoltaic expansion device based on photovoltaic power generation technology so that car owners can carry it with them and open it for use when going out.

[0004] However, the foldable photovoltaic expansion devices currently available on the market have many problems and are not perfect. For example, the solar photovoltaic panel assembly provided by the Chinese utility model patent (patent number CN 219287444 U) uses a driving part and a telescopic pneumatic rod to push the photovoltaic panel to unfold and retract. The overall weight of the equipment is heavy, which is not convenient for the owner to carry and set up. Secondly, the thrust center of the telescopic pneumatic rod is at the center of the sub-frame, which is prone to uneven force and easy to shake. Secondly, there are also belts that are worn in the middle of the sub-frame as transmission. Similarly, the belt structure also has disadvantages such as uneven force, so it is necessary to improve it. . Utility Model Content

[0034] The following are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention.

[0035] like Figures 1 to 10 As shown, the utility model provides a photovoltaic power generation expansion device for new energy vehicles, which includes a main frame 1, at least two sub-frames 2 slidably arranged on the main frame 1, and a telescopic drive mechanism for driving the sub-frames 2 to extend and retract. One sub-frame 2 is arranged horizontally relative to the main frame 1 and can slide and expand horizontally, and the other sub-frame 2 is arranged longitudinally relative to the main frame 1 and can slide and expand longitudinally. The sub-frames 2 arranged horizontally and / or longitudinally are equipped with a secondary expansion frame 4 arranged slidably.

[0036] Each sub-frame 2 and the secondary deployment frame 4 is equipped with a sub-photovoltaic panel 20;

[0037] The telescopic driving mechanism is equipped with multiple sets of driving modules 3;

[0038] During specific operation, a driving module 3 drives the transversely arranged sub-frame 2 to expand transversely relative to the main frame 1, and the driving module 3 drives the longitudinally arranged sub-frame 2 to expand longitudinally relative to the main frame 1. At this time, the two transversely and longitudinally arranged sub-frames 2 can be expanded simultaneously or one after another. After the sub-frame 2 is in place, another driving module 3 drives the secondary expansion frame 4 to expand transversely for the second time relative to the corresponding sub-frame 2.

[0039] Specifically, the device is generally used as a vehicle-mounted external charging expansion device. When it is used, it can be quickly built by simply placing the main frame 1 on the roof. It is suitable for a wide range of scenarios and is highly practical.

[0040] More specifically, each driving module 3 includes a driver, a pulley assembly, a steel wire rope 30 wound around the pulley assembly, and a sliding member passing through the steel wire rope 30. The driver drives the steel wire rope 30 to be retracted and released so as to be driven by the sliding member.

[0041] Since there are multiple drive modules 3 configured here, in order to better explain the working principle of the drive module 3, the following takes the drive module 3 driving the horizontally set sub-frame 2 as an example to explain the working process of the drive module 3 driving the sub-frame 2 to unfold, and the driver drives the wire rope 30 to retract and release, so that the sliding part slides with the wire rope 30, and then drives the sub-frame 2 to horizontally expand or retract and reset. Specifically, the retraction and extension of the sub-frame 2 is determined by the winding direction of the wire rope 30. For example, when the wire rope 30 is set to release the wire, the sliding part moves outward, that is, the sub-frame 2 is horizontally unfolded. Conversely, when the wire rope 30 is retracted, the sub-frame 2 is retracted and reset.

[0042] The utility model adopts a steel wire rope 30 and a pulley assembly as a transmission component. The structural design solves the problem that the center of gravity of the sub-frame is centered when belt transmission is used in the traditional design, but there is left-right imbalance and shaking. Secondly, compared with the structure on the market that uses cylinder parts as the drive, the steel wire rope structure has the advantages of weight reduction, light weight and low cost.

[0043] In a more specific technical solution, the number of the sub-frames 2 arranged transversely is set to at least two, and the two sub-frames 2 arranged transversely are respectively equipped with at least one sub-photovoltaic panel 20, and the sliding directions of the two sub-frames 2 arranged transversely are relatively opposite, and the two sub-frames 2 arranged transversely are simultaneously unfolded transversely, and the two sub-frames 2 arranged transversely are respectively located on the left and right sides of the main frame 1;

[0044] Similarly, the number of the longitudinally arranged sub-frames 2 is set to at least two, and the two longitudinally arranged sub-frames 2 are respectively equipped with at least one sub-photovoltaic panel 20. The sliding directions of the two longitudinally arranged sub-frames 2 are relatively opposite. The two longitudinally arranged sub-frames 2 are longitudinally unfolded at the same time, and the two longitudinally arranged sub-frames 2 are respectively located on the front and rear sides of the main frame 1.

[0045] It is worth explaining that the number of the sub-frames 2 arranged laterally includes but is not limited to two, and may also be three, four or more. Similarly, as a preferred choice, in this embodiment, the number of the sub-frames 2 is set to two.

[0046] In a more preferred solution, each of the longitudinally arranged sub-frames 2 is equipped with at least two of the secondary expansion frames 4 .

[0047] During operation, the two transversely arranged sub-frames 2 and the two longitudinally arranged sub-frames 2 are unfolded simultaneously. When fully unfolded, the secondary unfolding frame 4 is horizontally unfolded for the second time relative to the longitudinal sub-frame 2 , and the two secondary unfolding frames 4 are respectively located on the left and right sides of the longitudinal sub-frame 2 .

[0048] More specifically, Figure 1 As shown, each of the sub-frames 2 arranged horizontally and each of the secondary expansion frames 4 are set as small frames, and each of the sub-frames 2 arranged vertically is set as a large frame. That is, in a preferred solution, the sub-frames 2 arranged horizontally and the secondary expansion frames 4 are configured as small frames of the same model, which can be used interchangeably, while the sub-frames 2 arranged vertically are set as large frames. The three frames only differ in size, so that the overall length and height of the equipment appear more suitable, the mass distribution of the equipment is more uniform, and the overall stability and coordination are better. Of course, the size type of each sub-frame 2 arranged horizontally or vertically and the secondary expansion frame 4 can be customized according to actual customer needs without specific restrictions.

[0049] It is worth noting that in the preferred technical solution, Figure 1 As shown, only the sub-frames 2 arranged in the longitudinal direction are equipped with the secondary expansion frame 4 , while the sub-frames 2 arranged in the transverse direction are not equipped with the secondary expansion frame 4 .

[0050] More specifically, in this embodiment, the main frame 1 is provided with at least one main layer and at least two sub-layers, the main layer and each sub-layer are stacked up and down, the main layer is fixedly equipped with a main photovoltaic panel, and in the initial state, the sub-frame 2 arranged horizontally is built into the first sub-layer, and the sub-frame 2 arranged vertically is built into the second sub-layer;

[0051] The longitudinally arranged sub-frame 2 has at least one sub-main layer and at least two secondary sub-layers. The sub-main layer and each secondary sub-layer are stacked up and down. In the initial state, the first secondary expansion frame 4 is built into the first secondary sub-layer, and the second secondary expansion frame 4 is built into the second secondary sub-layer. The sub-photovoltaic panel 20 of the sub-frame 2 is located in the sub-main layer.

[0052] It is worth noting that, in order to better demonstrate the specific structure of the main frame 1, the main photovoltaic panel is not marked in the figure.

[0053] In the preferred scheme, the two transversely arranged sub-frames 2 are respectively equipped with a sub-photovoltaic panel 20, the two longitudinally arranged sub-frames 2 are each equipped with a sub-photovoltaic panel 20, and the four secondary expansion frames 4 are equipped with a sub-photovoltaic panel 20. The equipment is equipped with a total of 9 photovoltaic panels, which greatly improves the power consumption of the equipment.

[0054] Preferably, the number of sub-layers of the main frame 1 is generally set to four, two of which are used to accommodate two sub-frames 2 arranged horizontally, and the other two are used to accommodate two sub-frames 2 arranged vertically.

[0055] Each of the longitudinally arranged sub-frames 2 is also provided with two secondary sub-layers for accommodating the secondary expansion frames 4 .

[0056] In this embodiment, the pulley assembly includes pulley 1 31, pulley 2 32, pulley 3 33 and pulley 4 34 respectively arranged at the four corners of the main frame 1, and the sliding member includes slider 1 35 and slider 2 36.

[0057] Specifically, according to the unfolding direction of the sub-frame and the secondary unfolding frame 4, there are various settings, arrangements and wire rope winding methods of the pulley 1 31, the pulley 2 32, the pulley 3 33 and the pulley 4 34.

[0058] Since the expansion stroke of the transversely arranged sub-frame 2 and the secondary expansion frame 4 is short, that is, the span is small, the following can be adopted: Figure 6The winding method shown is implemented here. Here, in order to better explain the working principle of the wire rope 30, each roller and the sliding part, the following is a specific explanation taking the unfolding of the transversely arranged sub-frame 2 as an example: the first section of the wire rope 30 is wound between pulley one 31 and pulley two 32, the second section of the wire rope 30 is wound between pulley two 32 and pulley three 33, the third section of the wire rope 30 is arranged between pulley three 33 and pulley four 34, the fourth section of the wire rope 30 is arranged between pulley four 34 and pulley one 31, the slider one 35 is passed through the first section of the wire rope 30, the slider two 36 is passed through the third section of the wire rope 30, the two sides of the first sub-frame 2 are respectively connected to the slider one 35 and the slider two 36 of the first drive module 3, the two sides of the second sub-frame 2 are respectively connected to the slider one 35 and the slider two 36 of the second drive module 3, and the two sides of the secondary unfolding frame 4 are respectively connected to the slider one 35 and the slider two 36 of the third drive module 3.

[0059] And, in Figure 6 In the figure, the first section of the steel wire rope 30 is marked as 30a, the second section of the steel wire rope 30 is marked as 30b, the third section of the steel wire rope 30 is 30c, and the fourth section of the steel wire rope 30 is 30d, and the transmission direction of each section of the steel wire rope 30 is marked with an arrow.

[0060] That is, if Figure 6 As shown, the steel wire rope 30 is in a winding structure that is roughly a parallelogram. As the steel wire rope 30 is driven, the slider 1 35 and the slider 2 36 slide in a specified direction, thereby driving the corresponding sub-frame 2 to slide, so that the sub-frame 2 is relatively unfolded.

[0061] It is worth noting that, in order to make the sliding more stable and solve the shaking problem, at this time, the number of sliders in the sliding member is set to at least two, that is, including slider 1 35 and slider 2 36, and they are respectively arranged on both sides of the sub-frame 2. Of course, the technical solution can also be realized by configuring only one slider, and the number of sliders can also be configured to be three, four or more, which will not be specifically described here.

[0062] In a further embodiment, the winding method can also be adopted as follows Fig. 9 The winding method shown, that is, preferably, the pulley four 34 controlling the two groups of sub-frames 2 shares one, and the wire rope is also set to one. With this structural design, the number of wire ropes can be simplified to one, or the original two can be maintained, thereby achieving a material saving effect. Its specific working principle is consistent with the above-mentioned scheme, so it will not be repeated here.

[0063] Similarly, since the longitudinally arranged sub-frame 2 has a longer unfolding stroke, that is, a larger span, the following can be used: Figure 8The working principle of the winding method shown is consistent with the above scheme, so it will not be repeated here.

[0064] In addition, the utility model has another improvement point, that is, the two symmetrically arranged horizontal sub-frames 2 can be driven by the same driving module 3. Similarly, the two symmetrically arranged longitudinal sub-frames 2 can be driven by the same driving module 3. Even the secondary expansion frame 4 arranged on the same sub-frame 2 is also driven by the same driving module 3.

[0065] The specific description is as follows: each of the driving modules 3 is configured with at least two groups of the pulley assemblies and at least two of the steel wire ropes 30, one steel wire rope 30 is correspondingly wound around one pulley assembly, and each steel wire rope 30 is provided with a sliding member, the driver is provided with a winding drum 37 and a driving member 38 for driving the winding drum 37 to rotate, one steel wire rope 30 is forwardly wound around the winding drum 37, and the other steel wire rope 30 is reversely wound around the winding drum 37, the rotating winding drum 37 makes the retraction and release states of the two steel wire ropes 30 opposite, so that the movement directions of the two sliding members are opposite, and the heads of the two steel wire ropes 30 can be fixed to any position of the main frame 1.

[0066] The driving member 38 may be configured as an electric motor or a motor to drive the winding drum 37 to rotate.

[0067] During specific assembly, the head of the wire rope 30 is fixed to any position of the main frame 1, that is, independent of the winding drum 37, and the two wire ropes 30 are wound on the winding drum 37 in opposite winding directions, that is, as the winding drum 37 rotates, one wire rope 30 is in a winding state, and the other wire rope 30 is in a unwinding state, that is, the movement directions of the two sliding members are opposite, thereby realizing the relative expansion of the two sub-frames 2, and, as one wire rope 30 is winding, the other wire rope 30 is unwinding, that is, the amount of wire wound on the winding drum 37 is fixed. Compared with the winding structure in which the head and tail of a single wire rope are fixed to the winding drum, such a winding structure of the utility model is more miniaturized.

[0068] In simple terms, the two symmetrically arranged frames are driven by the same set of driving modules 3, the winding directions of the respective steel wire ropes 30 are set to be opposite, and the two steel wire ropes 30 are simultaneously wound on the same winding drum 37, so that the winding drum 37 can be driven to rotate by a motor or an electric motor, and the amount of wire on the winding drum 37 can be kept fixed, that is, the same amount of winding on the winding drum can achieve bidirectional movement.

[0069] Similarly, the working principle of the secondary expansion of each secondary expansion frame 4 relative to the sub-frame 2 is the same as described above. The difference between the two is that the positions of pulley 1 31, pulley 2 32, pulley 3 33 and pulley 4 34 are set to the respective corners of the longitudinally arranged sub-frame 2, so it will not be repeated here.

[0070] Specifically, each driving module 3 is also provided with a pull-out guide rail 10, and the pull-out guide rail 10 has at least two sections. The first section of the pull-out guide rail 10 is fixedly arranged, and the second section of the pull-out guide rail 10 is slidably assembled on the first section of the pull-out guide rail 10, and the second section of the pull-out guide rail 10 can be pulled out relative to the first section. The sliding member is fixedly assembled on the second section of the pull-out guide rail 10 to drive the second section of the pull-out guide rail 10 to slide, and each sub-frame 2 and the secondary expansion frame 4 are fixedly assembled on the second section of the corresponding pull-out guide rail 10.

[0071] Specifically, when the sub-frame 2 slides relative to the main frame 1, the first section of the corresponding pull-out guide rail 10 is fixedly assembled to the main frame 1, and at this time, the second section of the pull-out guide rail 10 is fixedly connected to the sub-frame 2. When the secondary expansion frame 4 slides relative to the sub-frame 2, at this time, the first section of the corresponding pull-out guide rail 10 is fixedly assembled to the sub-frame 2, and the second section of the pull-out guide rail 10 is fixedly connected to the secondary expansion frame 4. Similarly, in order to better explain the working principle of the utility model, Figure 4-Figure 5 In the figure, the sliding manner of the main frame 1 and the sub-frame 2 is taken as an example, and the first section of the pull-out guide rail 10 is marked as 10a, and the second section of the pull-out guide rail 10 is marked as 10b.

[0072] The utility model further ensures the sliding stability of the sub-frame 2 and the secondary expansion frame 4 through the structural design of the pull-out guide rail, and solves the problem of the center of gravity shifting and shaking.

[0073] In this embodiment, each of the pulley assemblies is configured with a plurality of pulley brackets 11, and pulley one 31, pulley two 32, pulley three 33 and pulley four 34 are respectively fixedly assembled on the pulley brackets 11. Specifically, the wheel pulley bracket 11 corresponding to the sub-frame 2 is fixedly assembled on the main frame 1, and the wheel pulley bracket 11 corresponding to the secondary deployment frame 4 is on the sub-frame 2 corresponding to the wheel pulley bracket 11.

[0074] More specifically, each of the pulley assemblies is equipped with a plurality of threading clamps 12, wherein the threading clamps 12 can be directly assembled on the main frame 1, or assembled to the corresponding pulley bracket 11, and the specific position of the threading clamp 12 can be set between two adjacent rollers, that is, the threading clamp 12 is inserted into the first section, the second section, the third section and / or the fourth section of the wire rope 30, for example, the threading clamp 12 is set between pulley 1 31 and pulley 2 32, and at this time, the specific number of the threading clamps 12 is not limited.

[0075] Of course, in a preferred solution, a threading clamp 12 can also be set around each roller, such as a threading clamp 12 is set at the position of each pulley 1 31, each pulley 2 32, each pulley 3 33 and each pulley 4 34. Similarly, the number of threading clamps 12 is not limited. Before the wire rope 30 passes through the pulley each time, the wire rope 30 first passes through the threading clamp 12 and then passes through the corresponding pulley. Such a structure can prevent the wire from being derailed during long-term operation and maintain the stability of the equipment. It is worth noting that the specific structure of the threading clamp 12 is not limited, and the actual assembly can use a common wire clamp or threading fixture on the market.

[0076] In this embodiment, each of the driving modules 3 is also configured with a trigger switch 13 and a position sensor 14. When the sub-frame 2 is unfolded into position relative to the main frame 1, and when the secondary unfolding frame 4 is unfolded into position relative to the sub-frame 2, the position sensor 14 is triggered and cooperated with the trigger switch 13.

[0077] like Figure 5 As shown, the trigger switch 13 can be a contact switch, and the in-position sensing element 14 can be a contact spring, and the triggering is realized through the contact structure. Fig.10 As shown, the trigger switch 13 can adopt a probe socket, and the in-position sensor can adopt a trigger probe, and the trigger is realized through the plug-in structure, thereby serving as a signal transmission. Moreover, the mechanical performance of the plug-in structure is more stable, and the connection stability between the sub-frame 2 and the main frame 1 can also be enhanced.

[0078] Among them, the specific positions of the trigger switch 13 and the in-place sensor 14 are set as follows: in the relative movement between the sub-frame 2 and the main frame 1, the trigger switch 13 is fixedly assembled on the main frame 1, and the in-place sensor 14 is fixedly assembled on the corresponding sub-frame 2; and in the relative movement between the secondary expansion frame 4 and the sub-frame 2, the trigger switch 13 is fixedly assembled on the corresponding sub-frame 2, and the in-place sensor 14 is fixedly assembled on the corresponding secondary expansion frame 4.

[0079] More specifically, the photovoltaic power generation expansion device is also provided with a control system, and the in-position sensing member 14 cooperates with the contact switch trigger to generate an in-position signal, and the control system receives the in-position signal. In actual applications, the control system is electrically connected to each driving member 38. For example, when the longitudinally arranged sub-frame 2 is stored or not in position relative to the main frame 1, the driving member 38 that controls the secondary expansion frame 4 is in a shutdown or standby state at this time, and when the sub-frame 2 is in position, the control system sends an action signal to the corresponding driving member 38, thereby controlling the secondary expansion frame 4 to expand at this time; of course, in addition to serving as a secondary expansion signal, the in-position signal can also be used as the start of power collection of the secondary photovoltaic panel 20 after the sub-frame 2 is in position or the secondary expansion frame 4 is in position, and the control system background can monitor the power collection information of the secondary photovoltaic panel 20, etc.
