Detailed Implementation

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0045] See appendix Figure 1 - Appendix Figure 14 An extended photovoltaic panel structure includes a support body 1 and a photovoltaic panel assembly 2; the photovoltaic panel assembly 2 includes a first photovoltaic panel 21, a second photovoltaic panel 22 and a third photovoltaic panel 23; the first photovoltaic panel 21 and the second photovoltaic panel 22 are respectively installed on both sides of the support body 1 and have tilt angles, and the first photovoltaic panel 21 and the second photovoltaic panel 22 have different orientations; the third photovoltaic panel 23 and the second photovoltaic panel 22 are rotatably connected or slidably connected, and the third photovoltaic panel 23 has a first position overlapping the second photovoltaic panel 22 and a second position extending away from the second photovoltaic panel 22.

[0046] Specifically, under normal circumstances, the third photovoltaic panel 23 is in a second position that expands away from the second photovoltaic panel 22. Both the second and third photovoltaic panels can be exposed to sunlight and convert sunlight into electrical energy for storage. As time goes by, the angle of sunlight changes, and the first photovoltaic panel 21 can be exposed to sunlight in that direction and convert it into electrical energy for storage. When encountering severe weather such as strong winds or heavy snow, the third photovoltaic panel 23 can be flipped / slid to a second position that overlaps the second photovoltaic panel 22 to reduce the overall volume of the photovoltaic panel assembly 2 and reduce wind resistance and stress surface.

[0047] In summary, by installing a first photovoltaic panel 21 and a second photovoltaic panel 22 on the support body 1, this utility model ensures that the area exposed to sunlight meets basic requirements. The different orientations of the first photovoltaic panel 21 and the second photovoltaic panel 22 allow for exposure to sunlight from multiple directions, thus ensuring power generation efficiency. By setting a rotatable / sliding third photovoltaic panel 23 on the second photovoltaic panel 22, the number of photovoltaic panels is increased to further increase the area exposed to sunlight, thereby improving power generation. Furthermore, the position of the third photovoltaic panel 23 can be adjusted to reduce the possibility of it being damaged by heavy pressure in harsh environments.

[0048] It should be noted that the expandable photovoltaic panel structure in this utility model can be fixedly installed outdoors or installed on a mobile trailer. Due to its diverse application scenarios, this utility model does not impose any restrictions on it. For ease of understanding, in this embodiment, the expandable photovoltaic panel structure is applied to a mobile energy storage trailer for reference. The mobile energy storage trailer consists of a vehicle body and a control unit (not shown in the figure) and a battery (not shown in the figure) installed in the vehicle body. The support body 1 of the expandable photovoltaic panel structure is installed on the top of the vehicle body. The control unit is electrically connected to the battery and the photovoltaic panel assembly 2 of the expandable photovoltaic panel to realize the conversion of solar energy and the storage of energy. At the same time, when the expandable photovoltaic panel structure is installed on the trailer, since the third photovoltaic panel 23 can be stacked and stored, the wind resistance during movement can be reduced and the transportation convenience can be improved.

[0049] See appendix Figure 1 - Appendix Figure 2 and attached Figure 5 - Appendix Figure 8 The first photovoltaic panel 21 is provided with a first fastening frame 210, and the second photovoltaic panel 22 is provided with a second fastening frame 220. The first fastening frame 210 and the second fastening frame 220 are respectively installed on both sides of the support body 1 and have an inclination angle, and the first fastening frame 210 and the second fastening frame 220 have different orientations; the third photovoltaic panel 23 is provided with a third fastening frame 230, and the third fastening frame 230 is rotatably connected to the second fastening frame 220.

[0050] Specifically, the first fastening frame 210 and the second fastening frame 220 are designed with different tilt angles and orientations, so that the first photovoltaic panel 21 and the second photovoltaic panel 22 have different tilt angles and orientations, thereby ensuring that the first photovoltaic panel 21 and the second photovoltaic panel 22 can be adapted to contact with sunlight from multiple directions to ensure power generation efficiency; while the third fastening frame 230 and the second fastening frame 220 are rotatably connected, which makes it convenient for the third photovoltaic panel 23 to switch between the first position and the second position by flipping, thereby increasing the number of photovoltaic panels to increase power generation, and reducing the area of ​​the photovoltaic panel module 2 to reduce wind resistance and stress surface, and reduce the possibility of overall damage.

[0051] See appendix Figure 5 - Appendix Figure 9 The second fastening frame 220 is equipped with a connecting seat 221 with a stop block 222, and the third fastening frame 230 is equipped with a rotating seat 231 with a pressure block 232. The rotating seat 231 is rotatably mounted on the connecting seat 221 so that the third photovoltaic panel 23 and the second photovoltaic panel 22 are rotatably connected, and the pressure block 232 can contact the stop block 222 as the third photovoltaic panel 23 rotates.

[0052] Specifically, when the third photovoltaic panel 23 is overlapping the first position, the pressure block 232 moves away from the abutment block 222; when the third photovoltaic panel 23 is flipped to the second position, the pressure block 232 contacts and adheres to the abutment block 222 to limit the rotation range of the third photovoltaic panel 23 and ensure that the third photovoltaic panel 23 can stably stay in the current position.

[0053] It should be noted that, in addition to using the connecting seat 221 and the rotating seat 231, rotating structures such as hinges, pivots, and rotary joints (not shown in the figure) may be used to achieve the rotating connection between the first fastening frame 210 and the second fastening frame 220. Since there are various related rotating structures, this utility model does not limit them.

[0054] See appendix Figure 5 - Appendix Figure 11 The present invention also includes a linkage lock 3, which includes a first indexing pin 31 and a second indexing pin 32 mounted on a rotating seat 231. A first locking hole 2211 and a second locking hole 2212 are provided on the connecting seat 221. When the third photovoltaic panel 23 is in the first position, the tip 300 of the first indexing pin 31 can be aligned and inserted into the first locking hole 2211 to lock the third fastening frame 230. When the third photovoltaic panel 23 is in the second position, the tip 300 of the second indexing pin 32 can be aligned and inserted into the second locking hole 2212 to lock the third fastening frame 230.

[0055] Therefore, the design of the linkage lock 3 can lock the rotating seat 231 onto the connecting seat 221 when the third photovoltaic panel 23 is in the first and second positions, preventing the third photovoltaic panel 23 from shaking or flipping during use or after overlapping, thus further improving the stability of the photovoltaic panel assembly 2. At the same time, since the first indexing pin 31 and the second indexing pin 32 are set on the rotating seat 231, they can avoid blocking or contacting the second photovoltaic panel 22 and the third photovoltaic panel 23, reducing the possibility of damage to the second photovoltaic panel 22 and the third photovoltaic panel 23.

[0056] Among them, as attached Figure 9 - Appendix Figure 11As shown, the indexing screw is an existing product, mainly comprising a screw head 300, a bolt 301, a positioning nut 302, a second spring 303, and a knob 304. The bolt 301 is fixedly mounted on the rotating seat 231 by the positioning nut 302, and the bolt 301 has a moving groove 3011 inside, and a retaining slot 3012 connecting to the moving groove 3011 is provided at the outer end of the bolt 301. The screw head 300 is slidably mounted in the moving groove 3011, and the tail end of the screw head 300 can pass through the moving groove 3011 to correspond to the first locking hole 2211 or the second locking hole 2212. The head end of the screw head 300 can pass through the moving groove 3011 to connect to the knob 304, and the knob 304 is provided with a retaining block 3041. The second spring 303 is installed in the moving groove 3011 and abuts against... The tip 300 connects to the inner wall of the moving groove 3011; when the knob 304 is moved and rotated so that the locking block 3041 disengages from the latch 3012 and abuts against the end of the sleeve 301, the tail end of the tip 300 retracts into the moving groove 3011 to disengage from the first locking hole 2211 or the second locking hole 2212, thereby completing the unlocking between the rotating seat 231 and the connecting seat 221, and at this time the second spring 303 deforms and stores energy; after rotating the knob 304 so that the locking block 3041 aligns with the latch 3012, the knob 304 is released, the second spring 303 releases energy and returns to its original state and drives the tip 300 to reset, so that the tail end of the tip 300 moves out of the moving groove 3011 to insert into the first locking hole 2211 or the second locking hole 2212, thereby completing the locking between the rotating seat 231 and the connecting seat 221.

[0057] It should be noted that there are various types of scaled-down models on the market, and this utility model does not limit them. The above embodiments are for reference only. On the other hand, in addition to using the linkage lock 3, other locking components can also be used to lock and release the second fastening frame 220 and the third fastening frame 230. Other locking components can also be directly installed on the second photovoltaic panel 22 and the third photovoltaic panel 23. Since the types and installation methods of related locking components are diverse and relatively conventional in the mechanical field, this utility model does not limit them.

[0058] See appendix Figure 5 - Appendix Figure 8 The second fastening frame 220 is equipped with a buckle 223, and the third fastening frame 230 is equipped with a buckle seat 233. When the third photovoltaic panel 23 is in the first position, the buckle 223 engages with the buckle seat 233 to lock the third fastening frame 230. Therefore, the combined use of the buckle 223 and the buckle seat 233 can further prevent the third photovoltaic panel 23 from easily detaching from the second photovoltaic panel 22 when it is in the first position, and prevent the second photovoltaic panel 22 from shaking, thus improving wind resistance. The buckle 223 and the buckle seat 233 are also existing products and are widely used in the mechanical field. Therefore, their specific structures are not described in detail in this utility model.

[0059] See appendix Figure 5 - Appendix Figure 8 The second fastening frame 220 is also equipped with a pad 224 that protrudes from the surface of the second photovoltaic panel 22, and the third fastening frame 230 is also equipped with a pad 234 that protrudes from the surface of the third photovoltaic panel 23, and the pad 234 can contact the pad 224 as the photovoltaic panel rotates.

[0060] Specifically, when the third photovoltaic panel 23 is overlapping the first position, the pad 234 is away from the pad 224; when the third photovoltaic panel 23 is flipped to the first position, the pad 234 contacts and adheres to the pad 224 to provide a buffering effect, and at the same time, it can also prevent the surface of the second photovoltaic panel 22 and the surface of the third photovoltaic panel 23 from being damaged by rigid collision.

[0061] See appendix Figure 3 - Appendix Figure 4 and attached Figure 12 - Appendix Figure 14 In another embodiment, a first fastening frame 210 is provided on the first photovoltaic panel 21, and a second fastening frame 220 is provided on the second photovoltaic panel 22. The first fastening frame 210 and the second fastening frame 220 are respectively installed on both sides of the support body 1 and have an inclination angle, and the first fastening frame 210 and the second fastening frame 220 have different orientations. The third photovoltaic panel 23 is slidably installed on the second fastening frame 220 so that the third photovoltaic panel 23 can switch between the first position and the second position by sliding.

[0062] Specifically, the first fastening frame 210 and the second fastening frame 220 have tilt angles and different orientations to ensure power generation efficiency; while the third photovoltaic panel 23 and the second fastening frame 220 are slidably connected, which makes it convenient for the third photovoltaic panel 23 to switch between the first position and the second position by sliding, thereby increasing the number of photovoltaic panels to increase power generation, and reducing the area of ​​the photovoltaic panel module 2 to reduce wind resistance and stress surface, and reduce the possibility of overall damage.

[0063] See appendix Figure 12 - Appendix Figure 15 The second fastening frame 220 has a sliding cavity 2200 at the top or bottom of the second photovoltaic panel 22. A sliding opening 2201 connecting to the outside is provided on one side of the sliding cavity 2200. A self-locking slide rail 4 extending towards the sliding opening 2201 is installed on the inner wall of the sliding cavity 2200. The third photovoltaic panel 23 is located in the sliding cavity 2200 and is fixed to the telescopic end of the self-locking slide rail 4 so that the third photovoltaic panel 23 can enter and exit the sliding cavity 2200 through the sliding opening 2201. The telescopic end of the self-locking slide rail 4 is locked after moving to a specific position. The locking state of the telescopic end can be released by turning the unlocking switch 44 of the self-locking slide rail 4.

[0064] Specifically, under normal circumstances, the third photovoltaic panel 23 is placed in the receiving cavity and is in the first position. The telescopic end of the self-locking slide rail 4 is in a retracted state and locked to prevent the third photovoltaic panel 23 from falling out of the receiving cavity at will. When in use, first turn on the unlocking switch 44 to release the locking state of the telescopic end, and then pull the third photovoltaic panel 23 out of the receiving cavity to the second position through the slide 2201. At this time, the telescopic end of the self-locking slide rail 4 is in an extended state and locked to prevent the third photovoltaic panel 23 from shaking at will and affecting the use.

[0065] Among them, as attached Figure 14 - Appendix Figure 15 As shown, the self-locking slide rail 4 is an existing product, which mainly includes an outer rail 41, a middle rail 42, an inner rail 43, an unlocking switch 44, and a self-locking component (not shown in the figure). The outer rail 41, the middle rail 42, and the inner rail 43 are stacked and nested together in sequence, and the outer rail 41 is fixedly installed. The middle rail 42 is slidably connected to both the outer rail 41 and the inner rail 43. The self-locking component 44 is set on the outer rail 41 and located between the middle rail 42 and the inner rail 43. When the middle rail 42 and the inner rail 43 are extended to the appropriate position, the self-locking component 44 can lock the middle rail 42 and the inner rail 43 in the current position. The unlocking switch 44 can be set at the end of the outer rail 41 / middle rail 42 / inner rail 43. By toggling the unlocking switch 44, the restriction of the self-locking component 44 on the middle rail 42 and the inner rail 43 can be released, allowing the middle rail 42 and the inner rail 43 to slide normally.

[0066] In this embodiment, the outer rail 41 is installed on the inner wall of the sliding cavity 2200, and the middle rail 42 and the inner rail 43 are used as the telescopic ends of the self-locking slide rail 4. The inner rail 43 is fixed to the side of the third photovoltaic panel 23, so that the third photovoltaic panel 23 can enter and exit the sliding cavity 2200 through the slide opening 2201. When the third photovoltaic panel 23 is in the first position or the second position, the self-locking component 44 locks the inner rail 43 and the middle rail 42 by itself. The unlocking switch 44 is set near the slide opening 2201 so that the user can easily turn it to release the locking state of the self-locking component 44 on the inner rail 43 and the middle rail 42.

[0067] It should be noted that there are various types of self-locking slide rails on the market, and this utility model does not limit them. The above embodiments are for reference only. On the other hand, in addition to the above structure, other sliding components with locking functions can also be used to achieve sliding and locking between the second fastening frame 220 and the third photovoltaic panel 23. Since the types and installation methods of related sliding components are diverse and relatively conventional in the mechanical field, this utility model does not limit them.

[0068] Furthermore, this utility model also includes a limiting lock (not shown in the figure). The limiting lock is installed on the second fastening frame 220 and located next to the slide 2201. When the third photovoltaic panel 23 enters the sliding cavity 2200 and is in the first position, the limiting lock can lock or release the third photovoltaic panel 23. Therefore, the use of the limiting lock can further prevent the third photovoltaic panel 23 from easily detaching from the receiving cavity when in the first position, thereby improving the installation stability of the third photovoltaic panel 23. The limiting lock can also adopt a dividing pin, a latch 223, or other mechanisms. Due to their variety and wide application in the mechanical field, their specific structure will not be described in detail in this utility model.

[0069] See appendix Figure 1 - Appendix Figure 8 and attached Figure 12 - Appendix Figure 14 The present invention also includes a drive assembly 5, which includes a first drive member 51 and a second drive member 52; the first fastening frame 210 and the second fastening frame 220 are both rotatably connected to the support body 1; the first drive member 51 is mounted on the support body and drivenly connected to the first fastening frame 210 to drive the first fastening frame 210 to rotate and adjust the tilt angle of the first photovoltaic panel 21; the second drive member 52 is mounted on the support body and drivenly connected to the second fastening frame to drive the second fastening frame 220 to rotate and adjust the tilt angle of the second photovoltaic panel 22.

[0070] Specifically, users can adjust the tilt angles of the first photovoltaic panel 21 and the second photovoltaic panel 22 respectively through the first drive component 51 and the second drive component 52 according to the changes in the angle of sunlight, so as to more accurately contact the sunlight at different times, further improving the adaptability and power generation rate of the photovoltaic panel module 2.

[0071] It should be noted that both the first driving component 51 and the second driving component 52 can be electrically driven or manually driven. Manufacturers can choose the appropriate option based on the user's cost requirements, and this invention does not impose any restrictions on this.

[0073] Secondly, see the appendix. Figure 3 - Appendix Figure 4 and attached Figure 12 - Appendix Figure 18 The first driving component 51 is a first electric push rod 510, and the cylinder and piston rod of the first electric push rod 510 are respectively hinged to the support body 1 and the first fastening frame 210; the second driving component 52 includes a rocker arm 521 and an adjusting part 522, and the support body 1 is provided with an insertion hole 1k; the rocker arm 521 is hinged to the second fastening frame 220, and the rocker arm 521 has a plurality of positioning holes 521k arranged in a straight line along its length; the adjusting part 522 includes a plug 5221, which can be inserted into the insertion hole 1 by passing through any positioning hole 521k one by one. k; wherein, the piston rod of the first electric push rod 510 is controlled to extend and retract to drive the first fastening frame 210 to rotate, thereby adjusting the tilt angle of the first photovoltaic panel 21, and the piston rod of the first electric push rod 510 is controlled to maintain the current state to fix the first photovoltaic panel 21 at the current angle; the swing rod 521 is moved to align the insertion hole 1k with the corresponding positioning hole 521k to adjust the tilt angle of the second photovoltaic panel 22, and then the insertion bolt 5221 can pass through the positioning hole 521k and be inserted into the insertion hole 1k to fix the second photovoltaic panel 22 at the current angle.

[0074] Further details are attached. Figure 16 - Appendix Figure 18As shown, the adjusting part 522 may further include a sliding sleeve 5222 and a first spring 5223. The sliding sleeve 5222 is slidably mounted on the rocker arm 521, and the sliding sleeve 5222 is provided with a movable cavity 52220. The plug 5221 is slidably mounted in the movable cavity 52220, and the first end of the plug 5221 penetrates through the movable cavity 52220 to the outside, and the tail end of the plug 5221 penetrates through the movable cavity 52220 to the positioning hole 521k. The plug 5221 is also provided with a baffle 52210 in the movable cavity 52220. The first spring 5223 is located in the movable cavity 52220 and sleeves the plug 5221. The two ends of the first spring 5223 abut against the baffle 52210 and the inner wall of the movable cavity 52220 respectively, so as to drive the tail end of the plug 5221 to penetrate through the positioning hole 521k and rotate to insert into the plug hole 1k.

[0075] Specifically, under normal circumstances, the first spring 5223 is in its initial state and drives the tail end of the plug 5221 to insert into the socket 1k, thereby locking the swing rod 521 onto the support body 1. When it is necessary to adjust the angle of the second photovoltaic panel 22, the head end of the plug 5221 is moved to drive the tail end of the plug 5221 to disengage from the socket 1k and the positioning hole 521k. Then, the sliding sleeve 5222 along the swing rod 521 is slid to the corresponding positioning hole 521k. Then, the head end of the plug 5221 is released, and the first spring 5223 releases energy to restore and drive the tail end of the plug 5221 to pass through the positioning hole 521k and insert into the socket 1k, thereby completing the adjustment and fixation of the tilt angle of the second photovoltaic panel 22.

[0076] See appendix Figure 2 Appendix Figure 4 Appendix Figure 8 and attached Figure 14 The actual orientation of the first photovoltaic panel 21, the second photovoltaic panel 22, and the third photovoltaic panel 23 is not limited in this utility model. For example, in this embodiment, the tilt angle of the first fastening frame 210 is complementary to the tilt angle of the second fastening frame 220, so that the second photovoltaic panel 22 is coplanar with the first photovoltaic panel 21 and has the same orientation; when the third photovoltaic panel 23 is in the second position, it is coplanar with the second photovoltaic panel 22 and has the same orientation.

[0077] Specifically, by adopting the above-mentioned usage method, the first photovoltaic panel 21, the second photovoltaic panel 22 and the third photovoltaic panel 23 can be coplanar and face the same direction, so as to maximize the area exposed to sunlight and further improve the power generation rate and power output of the photovoltaic panel module 2.

[0078] Furthermore, under normal circumstances, the first photovoltaic panel 21 and the second photovoltaic panel 22 can be symmetrically designed on both sides of the support body 1 to make the support body 1 more evenly stressed, improve the balance stability and pressure resistance of the photovoltaic panel assembly 2, and reduce the possibility of the connection between the support body 1 and the first fastening frame 210 and the second fastening frame 220 breaking during transportation.

[0079] It should also be noted that, although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application.
