Description

Technical Field

[0001] This invention belongs to the field of photovoltaic technology, specifically relating to a snap-on flip-top solar power bank. Background Technology

[0002] The main purpose of a solar-powered power bank is to provide power to electronic devices when you are out and about or traveling and there is no available power source for charging for an extended period. The solar photovoltaic panel provides this power, ensuring that the power bank can power your electronic devices for a considerable time. Its main components include the power bank casing, the solar panel, and a battery for energy storage.

[0003] However, with the increase in outdoor activities, existing solar power banks often experience insufficient power and cannot be replenished in time due to the limited number of solar panels. Chinese document CN215772637U discloses a foldable solar power bank with multiple solar photovoltaic panels arranged in layers inside. Chinese document CN215835175U discloses a foldable solar power bank that connects multiple photovoltaic panels continuously side-by-side, folding them within an electromagnet frame. Both types of solar power banks increase the area of ​​the photovoltaic panels and improve charging efficiency. However, without exception, they all require manually unfolding multiple solar photovoltaic panels, which is extremely inconvenient. Summary of the Invention

[0022] Preferably, the wedge-shaped shaft hole has:

[0023] A horizontal inner wall, parallel to the axis of the long connecting rod.

[0024] An inclined inner wall forms a wedge-shaped angle with the horizontal inner wall, and the wedge-shaped angle points above the button (above refers to the flip cover side of the power bank body).

[0025] Preferably, the locking hook end of the short connecting rod is a right-angled trapezoidal structure, the straight side of the right-angled trapezoid can be hooked and connected to the plate hole at the outer end of the telescopic solar photovoltaic panel, and the sloping side of the right-angled trapezoid is close to the button.

[0033] The elastic locking hook has a spring and a rotating hook that is pressed and connected to the spring. The spring is disposed inside the side wall of the flap, and the rotating hook matches and locks with the L-shaped barb of the movable locking rod.

[0034] The positive and progressive effects of this invention are as follows:

[0035] 1) By setting up fixed solar photovoltaic panels and retractable solar photovoltaic panels, this invention can improve the power efficiency of solar power banks and increase their battery life. Furthermore, the fixed and retractable solar photovoltaic panels can be charged simultaneously under sunlight, greatly shortening the charging time and improving charging efficiency.

[0036] 2) This invention achieves automatic unlocking and opening of the solar photovoltaic panels using a telescopic button device, eliminating the need for manual operation. The two ends of the inner sides of the two telescopic solar photovoltaic panels are connected by an elastic rope.

[0057] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. This patent can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this patent.

[0058] like Figure 1A and Figure 1BAs shown, the retractable solar power bank of the present invention has a power bank body 10 and a flip cover 20. For example, there are two flip covers 20, symmetrically arranged on the power bank body 10. Fixed solar photovoltaic panels 30 are fixed inside the power bank body 10 and on the inner surface of the flip covers 20. Two retractable solar photovoltaic panels 40 are slidably arranged on both sides of the power bank body 10, and four retractable solar photovoltaic panels 40 are slidably arranged on both sides of the inner surface of the flip covers 20. In this configuration, the retractable solar power bank of the present invention has a total of nine overlapping solar photovoltaic panels in a limited area, thus greatly improving energy storage efficiency. The retractable solar power bank of the present invention has a hinge 50, which rotates the first side of the flip cover 20 to the first side of the power bank body 10. The retractable solar power bank of the present invention also has a retractable button device 60 (or a flip cover button device 60), located inside the power bank body 10, which, along with the hinge 50, enables the flip cover 20 to open automatically. The retractable solar photovoltaic panel 40 can be unlocked and extended via the retractable button device 60. This invention's retractable solar power bank utilizes fixed solar photovoltaic panels 30 on the inner surfaces of the power bank body 10 and the flip cover 20, respectively, and retractable solar photovoltaic panels 40 that can extend from the inner surfaces of the power bank body 10 and the flip cover 20 to open all solar photovoltaic panels simultaneously, thus greatly improving charging time efficiency.

[0059] like Figure 2A As shown, the power bank body 10 is generally a square box structure with two opposing first sidewalls and two opposing second sidewalls. One of the second sidewalls is the button side, and the other is the non-button side. A circuit board may be located on one side of the box-shaped power bank body 10. Conventional features such as a USB port and charging port are provided on the sidewalls, for example, on the button side. Of course, these can also be located on other sidewalls of the power bank body 10. Regardless of which sidewall is used, the purpose of this invention can be achieved, and no limiting description is made in this invention.

[0060] A fixed solar photovoltaic panel 30 is fixed to the upper surface of the power bank body 10. The first sidewalls of the power bank body 10 are respectively provided with horizontally arranged U-shaped body slides 11. Two retractable solar photovoltaic panels 40 are slidably disposed within the U-shaped body slides 11 on the two first sidewalls of the power bank body 10, and are located below the fixed solar photovoltaic panels 30. The two retractable solar photovoltaic panels 40 are symmetrically and retractably placed on the button side and non-button side of the power bank body 10. Figure 2BAs shown, the outer ends of the telescopic solar photovoltaic panel 40 on the button side and the non-button side have plate holes 41, which can be locked to the locking hook end 631 of the corresponding short connecting rod 63 of the telescopic button device 60 to lock the telescopic solar photovoltaic panel 40 onto the power bank body 10. The box-shaped power bank body 10 has a fixing groove 12, which is horizontally fixed along the two first side walls inside the power bank body 10. The long connecting rod 62 of the telescopic button device 60 (see the following text for details) is axially movable and is set in the fixing groove 12. The second side wall of the power bank body 10 has a movable locking rod 13. The movable locking rod 13 has a long rod body, which is fixed to the second side of the telescopic solar photovoltaic panel 40. The long rod body has an L-shaped barb 131. The movable locking rod 13 can lock the flip cover 20 (see the following description of the flip cover 20 for details).

[0061] like Figure 3A As shown, the flip cover 20 has a door-like structure, roughly rectangular in shape, with two opposing first sides and two opposing second sides. The flip cover 20 is rotatably mounted on the first side wall of the power bank body 10 with its first sides facing each other. Each of the two opposing first sides of the flip cover 20 has a horizontally arranged U-shaped flip cover groove 21; the two sides of the telescopic solar photovoltaic panel 40 are slidably disposed within the U-shaped flip cover grooves 21 on the two first sides of the flip cover 20. Two fixed solar photovoltaic panels 30 can be symmetrically arranged on the upper surface of the flip cover 20. The telescopic solar photovoltaic panel 40 mounted on the flip cover 20 is located below the fixed solar photovoltaic panel 30. One side of the fixed solar photovoltaic panel 30 on the flip cover 20 has a mounting base 31. Continuing as... Figure 3B and 3C As shown, the second side wall of the flip cover 20 has an elastic locking hook 22. The elastic locking hook 22 and the movable locking rod 13 are connected by compression and latching, locking the flip cover 20 onto the power bank body. In a specific example, the elastic locking hook 22 has a spring (not shown) and a rotating hook 221 that is compressed and connected to the spring. The spring is located inside the side wall of the flip cover 20, and the rotating hook 221 matches and latches with the L-shaped barb 131 of the movable locking rod 13. In this way, the flip cover 20 is locked onto the power bank body 10. After pressing the button 61 of the telescopic button device 60, the locking hook end of the short connecting rod 63 of the telescopic button device 60 can be rotated to disengage from the telescopic solar photovoltaic panel 40, thereby releasing the compressive force between the elastic locking hook 22 and the movable locking rod 13, and further unlocking the elastic locking hook 22 and the movable locking rod 13 (see the telescopic button device 60 described later for details).

[0062] like Figures 4A-4DAs shown, specifically, the first side of the flip cover 20 is rotatably connected to the first side wall of the power bank body 10 in the form of a hinge 50, thereby covering the power bank body 10 with the flip cover 20. Specifically, the power bank body 10 has a body hinge seat 54 with shaft holes 541 fixed at both ends on the first side wall. The flip cover 20 has a cover hinge seat 56 with shaft holes 561 fixed at both ends on the first side. The hinge 50 has a hinge body 51, a body rotation shaft 55a, and a cover rotation shaft 55b. The hinge body 51 has a cross-section that is approximately racetrack-shaped, with a hinge cavity in the middle and openings 57 on both sides of the hinge cavity for accommodating the mounting base 31 of the fixed solar photovoltaic panel 30 on the flip cover 20. The hinge body 51 has two parallel body shaft holes 511 and a cover shaft hole 512 in the axial direction. The hinge body 51 has several spaced sections with transverse shaft holes 513a and 513b, which are perpendicularly connected to the shaft holes 511 and 512. The middle section of the body rotation shaft 55a passes through the shaft hole 511 of the hinge body 51, one end of which passes through the shaft hole 541 of the hinge seat 54, and the other end of which is located in the transverse shaft hole 513a of the hinge body 51. The middle section of the 55b rotates through the 512 shaft hole of the hinge body 51, one end of which passes through the shaft hole 561 of the 56 hinge seat 56, and the other end of which is located in the 513b shaft hole of the 51 hinge body 51.

[0063] Continue as Figure 4EAs shown, the hinge 50 has a body rotation shaft 55a and a cover rotation shaft 55b, each having a middle section 551, a first shaft end 552, and a second shaft end 553. The middle section 551 further has a first middle section 551a and a second middle section 551b. The second middle section 551b is bent and connected to the other end of the first middle section 551a. The middle section 551 passes through the body shaft hole 511 and the shaft hole 541 of the body hinge seat 54, or through the cover shaft hole 512 and the shaft hole 561 of the cover hinge seat 56. The first shaft end 552 is twisted perpendicularly connected to one end of the middle section 551 (specifically, to the first middle section 551a). The first middle section 551a passes through the body shaft hole 511 and the shaft hole 541 of the body hinge seat 54, or the shaft hole 561 of the cover shaft hole 512 and the cover hinge seat 56. The first shaft end 552 passes through the vertical end hole 542 inside the power bank body 10, and the vertical end hole 542 is perpendicularly connected to the shaft hole 541 of the body hinge seat 54. Alternatively, the first shaft end 552 passes through the vertical end hole 562 inside the flip cover 20, and the vertical end hole 562 of the cover is perpendicularly connected to the shaft hole 561 of the cover hinge seat 56. The second shaft end 553 is twisted approximately perpendicularly connected to the other end of the shaft middle section 551 (specifically, to the second shaft middle section 551b), and passes through the body transverse shaft hole 513a or the cover transverse shaft hole 513b of the hinge body 51. The second shaft middle section 551b is placed inside the hinge cavity. The hinge 50 is flipped by the torsional elasticity of the body rotation shaft 55a and the cover rotation shaft 55b.

[0064] This invention achieves automatic opening of the flip cover 20 and the power bank body 10 by setting the self-torque of the main body rotation axis 55a and the cover rotation axis 55b, which can automatically rotate 180 degrees. The automatic flip cover 20 is activated when a button is pressed. The hinge 50 of this invention not only connects the flip cover 20 and the power bank body 10, but also has an automatic opening function.

[0065] like Figures 5A-5E As shown, the telescopic button device 60 can also be used to unlock the flip cover 20, and is therefore also called the flip cover button device 60. The telescopic button device 60 has a button 61, a long connecting rod 62, a short connecting rod 63, and an elastic cord. The button 61 is located at one end of the button side of the power bank body 10. There are two long connecting rods 62, which are axially movable along the two first side walls inside the power bank body 10 and are horizontally close to the two first side walls. The button 61 is driven to one end of one of the long connecting rods 62. The middle part of the long connecting rod 62 has a protrusion 621 that can push the telescopic solar photovoltaic panel on the non-button side. The two ends of the long connecting rod 62 have a stepped shaft hole 622 near the second side wall and a wedge-shaped shaft hole 623 slightly away from the second side wall and pointing upwards towards the button 61.

[0066] The short connecting rods 63 consist of two pairs, each pair being positioned at both ends of the long connecting rod 62. Each short connecting rod 63 has a central shaft hole at its center, an inner end 632 with a side end shaft hole, and an outer end with a plate hole 41 (e.g., for hooking the telescopic solar photovoltaic panel 40 on the power bank body 10) on its outer side. Figure 2B The locking hook end 631 (as shown); the short connecting rod 63 and the long connecting rod 62 are connected by a central shaft 65 and a side shaft 66 passing through the inner end 632. Pressing the button 61 drives the long connecting rod 62 to move axially, thereby causing the short connecting rod 63 to rotate around the central shaft 65. The inner end 632 of the short connecting rod 63 rotates and approaches the telescopic solar photovoltaic panel, and the locking hook end 631 rotates and disengages from the telescopic solar photovoltaic panel 40 on the power bank body 10. At this time, the squeezing force between the elastic locking hook 22 and the movable locking rod 13 is removed, further unlocking the elastic locking hook 22 and the movable locking rod 33. Then, due to the elastic torque recovery effect of the flip shaft 55 in the hinge 50, the flip cover 20 is automatically lifted, thereby opening the flip cover 20. At this time, the telescopic button device 60 is also the flip cover button device.

[0067] like Figure 5F As shown, the elastic cord (not shown) consists of two cords, each with two ends of a hook 42 that connects to the inner ends of the two telescopic solar photovoltaic panels 40, and a middle section supported on the button-side fulcrum (e.g., a central shaft 65 set on the long connecting rod 62 and the short connecting rod 63) and the non-button-side fulcrum (e.g., a central shaft 65 set on the long connecting rod 62 and the short connecting rod 63) of the power bank body 10. After the telescopic solar photovoltaic panels 40 on the power bank body 10 are unlocked by the button 61, the elasticity of the elastic cord pulls the two telescopic solar photovoltaic panels 40 out of the second side wall of the power bank body 10. By pressing the button 61, the locking hook end 631 of the short connecting rod 63 rotates and disengages from the plate hole 41 on the telescopic solar photovoltaic panels 40 on the power bank body 10, unlocking them. The protrusion on the long connecting rod 62 pushes the telescopic solar photovoltaic panel 40 on the non-button side. Through the elastic recovery of the elastic rope, the two telescopic solar photovoltaic panels 40 connected at both ends are pulled out from the button side and the non-button side respectively, thereby causing the two telescopic solar photovoltaic panels 40 to extend. This invention uses a telescopic button device to lock the telescopic solar photovoltaic panels and automatically unlocks and extends the solar photovoltaic panels for solar charging by pressing the button.

[0068] Both ends of the central shaft 65 are fixed within the two walls of the fixing groove 12. One end of the central shaft 65 passes through the stepped shaft hole 622 of the long connecting rod 62, and the other end passes through the central shaft hole of the short connecting rod 63. In a specific example, the stepped shaft hole 622 of the long connecting rod 62 has a horizontally arranged lower n-shaped hole 6221, close to the button 61; the horizontally arranged upper n-shaped hole 6222 is away from the button 61, and the bottom end of the upper n-shaped hole 6221 is offset from the bottom end of the lower n-shaped hole 6222 but integrally connected. One end of the side shaft 66 passes through the wedge-shaped shaft hole 623 of the long connecting rod 62, and the other end passes through the side shaft hole of the short connecting rod 63. In one specific example, the wedge-shaped shaft hole 623 has a horizontal inner wall 6231, which is parallel to the axis of the long connecting rod 62. The inclined inner wall 6232 forms a wedge-shaped angle 6233 with the horizontal inner wall 6231, and the wedge-shaped angle 6233 points above the button 61 (above refers to the side of the flip cover on the power bank body). In one specific example, the locking hook end 631 of the short connecting rod 63 is a right-angled trapezoidal structure. The straight waist of the right-angled trapezoid can be hooked and connected to the plate hole 41 at the outer end of the telescopic solar photovoltaic panel, and the inclined waist of the right-angled trapezoid is close to the button 61.

[0069] like Figure 5G As shown, the telescopic button device 60 also has a steering rod 67, both ends of which are connected to the bottom of the long connecting rod 62. The center of the steering rod 67 is rotatably fixed to the bottom of the power bank body 10. When the button 61 is pressed, one long connecting rod 62 is pushed to move horizontally to the other side, while the steering rod 67 drives the other long connecting rod 62 to move horizontally in the opposite direction. This transmits the pushing force of the button 61 to the long connecting rod 62 on the opposite side.

[0070] The flip-top button device 60 also includes a button return compression spring 68, which is disposed in the fixing groove 12, with one end abutting against the button 61 and the other end abutting against the other end inside the fixing groove 12. The button 61 automatically returns to its original position by providing the button return compression spring 68 in the fixing groove 12.

[0071] like Figure 6As shown, the retractable solar power bank of the present invention also has an integrated silicone sheet 71 and a protective silicone sheet 72. One side of the integrated silicone sheet 71 is connected to one side of the retractable solar photovoltaic panel 40 that slides on the power bank body 10, and the other side of the integrated silicone sheet 71 is connected to one side of the retractable solar photovoltaic panel 40 that slides on the flip cover 20. When the retractable solar photovoltaic panel 40 on the power bank body 10 is unlocked and extended by the retractable button device 60, due to the integrated action of the integrated silicone sheet 71, the retractable solar photovoltaic panel 40 on the flip cover 20 is also automatically pulled out, thereby realizing the extension of all the retractable solar photovoltaic panels 40 from the flip cover 20. The protective silicone sheet 72 is wrapped around the integrated silicone sheet 71. One side of the protective silicone sheet 72 is connected to one side of the fixed solar photovoltaic panel 30 that is fixed on the power bank body 10, and the other side of the protective silicone sheet 72 is connected to one side of the fixed solar photovoltaic panel 30 that is fixed on the flip cover 20, for protecting the hinge.

[0072] When using the telescopic solar power bank of the present invention, pressing the button 61 on the button side of the power bank body 10 pushes the long connecting rod 62 of the telescopic button device 60, causing the short connecting rod 63 on the button side to rotate about the central axis 65. At this time, the locking hook end 631 of the short connecting rod 63 disengages from the plate hole 41 on the outer side of the telescopic solar photovoltaic panel 40. Due to the overall action of the long connecting rod 62, the short connecting rods 63 in other parts also rotate about their own central axis 65. The squeezing force between the movable locking rod 13 of the telescopic solar photovoltaic panel 40 and the elastic locking hook 22 on the second side of the flip cover 20 disappears, and the flip cover 20 is automatically opened by the elastic torque of the flip shaft 55 inside the hinge 50. Additionally, after the locking hook end 631 of the short connecting rod 63 of the telescopic button device 60 is disengaged from the plate hole 41 at the outer end of the telescopic solar photovoltaic panel 40, the protrusion 621 on the long connecting rod 62 pushes the telescopic solar photovoltaic panel 40 on the non-button side. Then, due to the elasticity of the elastic rope, the telescopic solar photovoltaic panels 40 connected at both ends are pulled out from the button side and non-button side of the power bank body 10. Then, due to the integrated silicone sheet 71, the telescopic solar photovoltaic panels 40 on the flip cover 20 are pulled out from the second side of the flip cover 20 respectively, and finally all the telescopic solar photovoltaic panels 40 are extended and retracted for charging.
