[0026] The following are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly.

[0027] As Figures 1 to 6 shown, a vehicle-mounted photovoltaic panel device with multi-directional expansion provided by the present invention includes a main frame 1, at least two sub-frames 2 slidably assembled on the main frame 1, several secondary expansion frames 4, and a telescopic drive mechanism. One sub-frame 2 is arranged horizontally relative to the main frame 1, and the other sub-frame 2 is arranged longitudinally relative to the main frame 1 and can be longitudinally slid and expanded. The secondary expansion frame 4 is slidably assembled on the horizontally arranged and / or longitudinally arranged sub-frame 2 and can be secondarily expanded relative to the sub-frame 2. Each sub-frame 2 and each secondary expansion frame 4 are respectively equipped with sub-photovoltaic panels 20;

[0028] The telescopic drive mechanism is configured with a plurality of in-place sensing components. Each in-place sensing component includes a trigger switch 13 and an in-place sensing member 14. When the horizontally arranged sub-frame 2 and / or the longitudinally arranged sub-frame 2 are expanded in place relative to the main frame 1, the corresponding in-place sensing member 14 cooperates with the corresponding trigger switch 13 by triggering, and the trigger switch 13 issues a primary in-place signal. When the secondary expansion frame 4 is expanded in place relative to the main frame 1, the corresponding in-place sensing member 14 cooperates with the corresponding trigger switch 13 by triggering, and the trigger switch 13 issues a secondary in-place signal.

[0029] This is generally used as an in-vehicle external charging expansion device. During specific use, only the main frame 1 needs to be set on the roof of the vehicle to quickly complete the construction. Through the sub-frame 2 telescopically extended from the main frame 1 and the secondary expansion frame 4 extended from the sub-frame 2, a plurality of sub-photovoltaic panels 20 are expanded in multiple directions, maximizing the expansion area of the photovoltaic panels, improving the overall power generation efficiency of the device, having a very wide range of applicable scenarios, meeting the user's demand for outdoor charging, and solving the technical problem of over-reliance on charging piles in the traditional power-taking mode.

[0030] Secondly, the expansion frames arranged horizontally and vertically make the overall length and height of the device more adaptable, the mass distribution of the device more uniform, and the overall stability and coordination better. Generally, the two sub-frames 2 arranged horizontally and vertically can be deployed simultaneously. After the sub-frame 2 is in place, the secondary expansion frame 4 is then deployed. The utility model effectively controls the deployment of each expansion frame by setting multiple groups of in-place induction components to prevent cross-collision of each frame on the horizontal plane, with high practicability.

[0031] In a preferred embodiment, the number of the horizontally arranged sub-frames 2 is set to at least two. Each of the two horizontally arranged sub-frames 2 is respectively equipped with at least one sub-photovoltaic panel 20. The sliding directions of the two horizontally arranged sub-frames 2 are opposite to each other. When the two horizontally arranged sub-frames 2 are horizontally deployed simultaneously, the two horizontally arranged sub-frames 2 are respectively located on the left and right sides of the main frame 1.

[0032] Similarly, the number of the vertically arranged sub-frames 2 is set to at least two. Each of the two vertically arranged sub-frames 2 is respectively equipped with at least one sub-photovoltaic panel 20. The sliding directions of the two vertically arranged sub-frames 2 are opposite to each other. When the two vertically arranged sub-frames 2 are vertically deployed simultaneously, the two vertically arranged sub-frames 2 are respectively located on the front and back sides of the main frame 1.

[0033] It should be noted that the number of the horizontally arranged sub-frames 2 includes, but is not limited to, the implementation mode of two, and can also be three, four or more. Similarly, as an optimal choice, in this embodiment, the number of the sub-frames 2 is set to two.

[0034] In a more preferred scheme, each of the vertically arranged sub-frames 2 is equipped with at least two secondary expansion frames 4.

[0035] During operation, the two horizontally arranged sub-frames 2 and the two vertically arranged sub-frames 2 are deployed simultaneously. When they are in place, the secondary expansion frames 4 are horizontally deployed secondarily relative to the vertical sub-frames 2, and the two secondary expansion frames 4 are respectively located on the left and right sides of the vertical sub-frame 2.

[0036] More specifically, as Figure 1As shown, each horizontally arranged secondary frame 2 and each secondary unfolding frame 4 are set as small frames, and each vertically arranged secondary frame 2 is set as a large frame. That is, in the preferred solution, the horizontally arranged secondary frame 2 and the secondary unfolding frame 4 are configured as small frames of the same model and can be used interchangeably, while the vertically arranged secondary frame 2 is set as a large frame. These three types of frames only differ in size. Such an arrangement makes the overall appearance more beautiful and the stability more coordinated. Of course, the size types of each horizontally arranged or vertically arranged secondary frame 2 and the secondary unfolding frame 4 can be customized according to the actual customer needs without specific restrictions.

[0037] It should be emphasized that in this embodiment, as Figure 1 shown, only the vertically arranged secondary frame 2 is assembled with the secondary unfolding frame 4, while the horizontally arranged secondary frame 2 is not assembled with the secondary unfolding frame 4.

[0038] In this embodiment, the trigger switch 13 is set as a probe socket, and the in-place sensing member 14 is configured as a trigger probe. When the trigger probe is inserted into the probe socket, the trigger probe is electrically connected to the probe socket.

[0039] Adopting the plug-in structure design of the probe and the socket can not only achieve signal transmission, but also, compared with the structure of the elastic sheet and the travel switch, the plug-in structure has more stable mechanical properties and can also strengthen the connection stability between the secondary frame 2 and the main frame body 1.

[0040] More specifically, the probe socket includes a seat body 130 and a needle sleeve 131 fixedly assembled on the seat body 130. The trigger probe includes a fixing member 140 and a plug pin 141 assembled on the fixing member 140. The needle sleeve 131 has a jack for the plug pin 141 to insert.

[0041] Among them, the specific positions of the trigger switch 13 and the in-place sensing member 14 are set as follows. During the relative movement between the secondary frame 2 and the main frame body 1, the trigger switch 13 is fixedly assembled on the main frame body 1, and the in-place sensing member 14 is fixedly assembled on the secondary frame 2; during the relative movement between the secondary unfolding frame 4 and the secondary frame 2, the trigger switch 13 is fixedly assembled on the secondary frame 2, and the in-place sensing member 14 is fixedly assembled on the secondary unfolding frame 4.

[0042] In this embodiment, the vehicle-mounted photovoltaic panel device further includes a main control system assembled on the main frame body 1;

[0043] Among them, the in-place sensing component and the telescopic driving mechanism are both electrically connected to the main control system. The main control system receives the initial in-place signal of the in-place sensing component and makes the telescopic driving mechanism drive the secondary unfolding frame 4 to unfold relative to the secondary frame 2 for the second time.

[0044] In addition, the in-place sensing component has the following functions: each auxiliary photovoltaic panel 20 is electrically connected to the main control system, and it can also start monitoring the power of the corresponding auxiliary photovoltaic panel 20 after the auxiliary frame 2 is unfolded into place, or the secondary unfolding frame 4 is unfolded into place, that is, after the main control system receives the initial in-place signal and / or the secondary in-place signal.

[0045] In this embodiment, the telescopic drive mechanism is equipped with multiple drive modules 3, each of which 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 extended so as to be driven by the sliding member;

[0046] The sliding member of one driving module 3 is used to drive the first sub-frame 2 to expand horizontally relative to the main frame 1 once, the sliding member of another driving module 3 is used to drive another sub-frame 2 to expand longitudinally relative to the main frame 1 once, and the sliding member of another driving module 3 is used to drive the secondary expansion frame 4 to expand horizontally for a second time relative to the corresponding sub-frame 2.

[0047] 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.

[0048] Wherein, the pulley assembly includes pulley 1 31, pulley 2 32, pulley 33 and pulley 4 34, the sliding member includes slider 1 35 and slider 2 36, the first section of the wire rope 30 is wound between pulley 1 31 and pulley 2 32, the second section of the wire rope 30 is wound between pulley 2 32 and pulley 3 33, the third section of the wire rope 30 is arranged between pulley 3 33 and pulley 4 34, the fourth section of the wire rope 30 is arranged between pulley 4 34 and pulley 1 31, slider 1 35 is passed through the first section of the wire rope 30, slider 2 36 is passed through the third section of the wire rope 30, both sides of the first sub-frame 2 are respectively connected to the slider 1 35 and slider 2 36 of the first drive module 3, both sides of the second sub-frame 2 are respectively connected to the slider 1 35 and slider 2 36 of the second drive module 3, and both sides of the secondary expansion frame 4 are respectively connected to the slider 1 35 and slider 2 36 of the third drive module 3.

[0049] 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.

[0050] 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.

[0051] 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 5 The 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.

[0052] And, in Figure 5 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.

[0053] That is, if Figure 5 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.

[0054] In a further implementation scheme, the winding method can also adopt the winding method shown below, 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 such a 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.

[0055] Similarly, since the longitudinally arranged sub-frame 2 has a longer unfolding stroke, that is, a larger span, the following can be used: Figure 6 The working principle of the winding method shown is consistent with the above scheme, so it will not be repeated here.

[0056] It should be noted that, in order to make the sliding more stable and solve the problem of shaking, at this time, the number of sliders in the sliding member is set to at least two, that is, including slider one 35 and slider two 36, and they are respectively arranged on both sides of the secondary frame 2. Of course, only configuring one slider can also implement this technical solution, and the number of sliders can also be configured as three, four or more, and no specific description is made here.

[0057] In addition, the present utility model also has another improvement point, that is, two symmetrically arranged laterally arranged secondary frames 2 can be driven by the same driving module 3. Similarly, two symmetrically arranged longitudinally arranged secondary frames 2 can be driven by the same driving module 3. Even, the secondary unfolding frames 4 arranged on the same secondary frame 2 are also driven by the same driving module 3.

[0058] The specific description is as follows: Each of the driving modules 3 is configured with at least two sets 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 one of the sliding members. The driver is provided with a wire winding disc 37 and a driving member 38 for driving the wire winding disc 37 to rotate. One steel wire rope 30 is wound around the wire winding disc 37 in the forward direction, and the other steel wire rope 30 is wound around the wire winding disc 37 in the reverse direction. The rotating wire winding disc 37 makes the winding and unwinding states of the two steel wire ropes 30 opposite, so that the moving 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.

[0059] Among them, the driving member 38 can be configured as a motor or a motor to drive the wire winding disc 37 to rotate.

[0060] During specific assembly, the head of the steel wire rope 30 is fixed to any position of the main frame 1, that is, independent of the wire winding disc 37, and the two steel wire ropes 30 are wound around the wire winding disc 37 in opposite winding directions. That is, when the wire winding disc 37 rotates, one steel wire rope 30 is in the wire winding state, while the other steel wire rope 30 is in the wire unwinding state. That is, the moving directions of the two sliding members are opposite, so as to realize the relative unfolding of the two secondary frames 2. Moreover, when one steel wire rope 30 is winding, the other steel wire rope 30 is unwinding, that is, the amount of wire wound around the wire winding disc 37 is fixed. Compared with the wire winding structure in which the head and tail of a single steel wire rope are both fixed to the wire winding disc, the wire winding structure of the present utility model is more miniaturized.

[0061] Briefly speaking, two symmetrically arranged frames are driven by the same set of driving modules 3. The winding directions of their respective steel wire ropes 30 are set to be opposite, and the two steel wire ropes 30 are wound around the same winding disc 37 at the same time. This can not only achieve the rotation of the winding disc 37 driven by one motor or electric machine, but also keep the wire quantity of the winding disc 37 fixed, that is, the equal wire quantity of the winding disc can achieve bidirectional movement.

[0062] Similarly, the working principle of the secondary unfolding of each secondary unfolding frame 4 relative to the secondary frame 2 is the same as above. The difference between the two is only that the positions of the first pulley 31, the second pulley 32, the third pulley 33 and the fourth pulley 34 are set at the respective corners of the longitudinally arranged secondary frame 2, so it will not be repeated here.

[0063] Specifically, each driving module 3 is also provided with a drawable guide rail 10. The drawable guide rail 10 has at least two sections. The first section of the drawable guide rail 10 is fixedly arranged. The second section of the drawable guide rail 10 is slidably assembled on the first section of the drawable guide rail 10, and the second section of the drawable guide rail 10 is drawable relative to the first section. The sliding member is fixedly assembled on the second section of the drawable guide rail 10 to drive the second section of the drawable guide rail 10 to slide. Each secondary frame 2 and secondary unfolding frame 4 are fixedly assembled on the second section of the corresponding drawable guide rail 10.

[0064] Specifically, when the secondary frame 2 slides relative to the main frame 1, the first section of the corresponding drawable guide rail 10 is fixedly assembled to the main frame 1. At this time, the second section of the drawable guide rail 10 is fixedly connected to the secondary frame 2. When the secondary unfolding frame 4 slides relative to the secondary frame 2, at this time, the first section of the corresponding drawable guide rail 10 is fixedly assembled to the secondary frame 2, and the second section of the drawable guide rail 10 is fixedly connected to the secondary unfolding frame 4. Similarly, in order to better illustrate the working principle of the present invention, in Figure 2 the sliding mode of the main frame 1 and the secondary frame 2 is taken as an example, and the first section of the drawable guide rail 10 is marked as 10a, and the second section of the drawable guide rail 10 is marked as 10b.

[0065] Through the structural design of the drawable guide rail, the present invention further ensures the sliding stability of the secondary frame 2 and the secondary unfolding frame 4, and solves the problem of center of gravity offset and shaking.

[0066] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
