Description

Technical Field

[0001] This utility model relates to the field of electric vehicle tail box technology, specifically to a solar-powered folding tail box. Background Technology

[0002] In today's urban transportation sector, electric two-wheelers have become a popular choice for short-distance daily commutes due to their flexibility, convenience, economy, and environmental friendliness. However, with their widespread use and the increasing diversification of user travel needs, electric two-wheelers have revealed several technical shortcomings that urgently need to be addressed in practical applications, as follows:

[0003] 1. The limitations of battery life and charging severely restrict travel range and efficiency.

[0004] (1) Limited range: Electric two-wheelers mainly rely on built-in batteries for power, but due to limitations in battery technology and vehicle space, their battery capacity is usually limited. This cannot meet users' needs for medium- and long-distance travel.

[0005] (2) Lack of charging facilities: Currently, the layout of public charging facilities has significant deficiencies. In cities, charging stations are mainly concentrated in densely populated areas such as commercial centers and large communities, while the coverage of charging stations in urban fringe areas, suburbs, and vast rural areas is extremely low. This makes it difficult for users to find suitable charging locations when their batteries run low in these areas.

[0006] (3) Additional power consumption increases power consumption: In actual use, users often use in-vehicle devices such as mobile phone navigation, and the additional power consumption will further consume the main battery power of the electric two-wheeler.

[0007] 2. High seat temperature reduces riding comfort.

[0008] In summer and high-temperature weather, when electric two-wheelers are parked outdoors for a period of time, the seat cushion is directly exposed to sunlight, causing the surface temperature of the seat cushion to rise rapidly. When the user prepares to ride again, it will not only cause severe discomfort, but may even cause skin burns.

[0009] 3. The tailgate's limited functionality fails to meet the needs of diverse scenarios.

[0010] Currently, the tail boxes equipped on electric two-wheelers on the market, whether they adopt a fixed structure or a simple folding structure, are usually limited to storing items. This single function cannot meet the diverse needs of users at the same time, and it is difficult to effectively improve users' overall satisfaction and user experience with electric two-wheelers. Utility Model Content

[0011] The purpose of this utility model is to provide a solar-powered folding tail box to solve the above-mentioned technical problems in the prior art; the preferred technical solution among the many technical solutions provided by this utility model can produce many technical effects, as detailed below.

[0012] To achieve the above objectives, the present invention provides the following technical solution:

[0013] This utility model provides a solar-powered folding tail box, comprising a foldable tail box body and a solar cell assembly, wherein: the foldable tail box body is disposed behind the seat cushion, and when the foldable tail box body is in a folded state, it forms a box structure for accommodating items, and when the foldable tail box body is in an unfolded state, it can cover the seat cushion; the solar cell assembly includes a solar panel module, and the solar panel module is disposed on the inner wall of the foldable tail box body.

[0014] Preferably, the solar-powered folding tail box includes a support assembly connected to the rear side of the seat cushion, and the foldable tail box body is disposed on the support assembly.

[0015] Preferably, the solar cell module includes an energy storage power source, which is electrically connected to the solar panel module.

[0016] Preferably, the solar cell module further includes a charging controller, and both the solar panel module and the energy storage power supply are electrically connected to the charging controller.

[0017] Preferably, the solar cell module includes a voltage regulator, which is electrically connected to the energy storage power supply, and the electric vehicle circuit system is electrically connected to the voltage regulator.

[0018] Preferably, the foldable tail box body includes a fixed bottom, a foldable body, and a lid; the solar panel module includes multiple unit panels, wherein: the fixed bottom is fixedly mounted on the support assembly; the foldable body includes multiple side panels mounted on the fixed bottom, adjacent side panels are detachably connected by a connecting assembly, at least one side panel is configured as a foldable panel, and the foldable panel is rotatably connected to the fixed bottom; the lid is rotatably connected to one of the foldable panels; and the unit panels are mounted on the inner wall of at least one of the fixed bottom, the foldable panels, and the lid.

[0019] Preferably, the connecting component is a magnetic component, and two adjacent side panels are connected by magnetic attraction through the magnetic component.

[0020] Preferably, the lid is provided with a locking assembly for locking the lid to a closed state.

[0021] Preferably, the lid is provided with a positioning insertion part, and the side panel is provided with a positioning engagement part corresponding to the position of the positioning insertion part. When the lid is closed, the positioning insertion part is engaged with the positioning engagement part.

[0022] Preferably, the lid of the box is provided with a display screen for displaying illumination information and energy storage information.

[0023] The solar-powered folding tail box provided by this utility model has at least the following beneficial effects:

[0024] 1. Solve the problems of battery life and charging, and improve travel flexibility:

[0025] The solar panel modules (including solar panel units) are installed on the inner wall of the foldable tailgate. When the tailgate is unfolded, the solar panels on the inner wall can fully receive sunlight, converting solar energy into electricity, enabling "recharging anytime, anywhere outdoors." This design breaks through the limitations of traditional electric two-wheelers that rely on fixed charging stations, and is especially suitable for long-term outdoor parking scenarios. It can extend the vehicle's range per charge and effectively alleviate "range anxiety."

[0026] 2. Solve the problem of seat cushion being exposed to direct sunlight, improving riding comfort:

[0027] When the foldable tailgate is in the unfolded state, it can cover the seat cushion. On the one hand, it prevents the surface temperature of the seat cushion from rising rapidly due to direct exposure to the sun; on the other hand, it can prevent dust, fallen leaves, rainwater and other impurities from adhering to the surface of the seat cushion, reducing the frequency of seat cushion cleaning.

[0028] 3. Integrates multiple functions to reduce usage costs:

[0029] This utility model's tail box possesses three major functions: storage, sun protection, and power generation. In its folded state, it serves as a standard tail box for storing items such as helmets, backpacks, and shopping bags, meeting basic storage needs. When unfolded, it provides sun protection for the seat cushion while simultaneously generating solar power. Furthermore, the integrated design does not increase the overall size of the vehicle (its folded size is comparable to a standard tail box), thus not affecting the vehicle's parking flexibility and achieving the highly efficient design goal of "one item for multiple uses."

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0041] Example 1:

[0042] This utility model provides a solar-powered folding tail box, see reference. Figures 1 to 7 As shown, the solar-powered folding tail box includes a foldable tail box body 1 and a solar cell module 2.

[0043] The foldable tailgate body 1 is a foldable structure and is located on the rear side of the seat cushion 4. The foldable tailgate body 1 can be folded into a folded state and can also be opened into an unfolded state. The solar cell module 2 includes a solar panel module 21, which is located on the inner wall of the foldable tailgate body 1 and moves synchronously with the foldable tailgate body 1.

[0044] In actual use, when the vehicle is stationary, the user can open the foldable tailgate body 1 to unfold it. At this time, the solar panel module 21 can collect solar energy and convert it into electrical energy.

[0045] When the vehicle is in motion, the user folds the foldable tailgate body 1 to put it in a folded state. At this time, the foldable tailgate body 1 has a box structure and is used to store items.

[0046] The main body 1 of this utility model of foldable tail box has two usage modes: folded and unfolded. When it is in the open state, it can effectively convert solar energy into electrical energy in conjunction with the solar panel module 21 to charge the electric vehicle battery. This not only effectively extends the driving range and solves range anxiety, but also makes charging convenient and not limited by the scene. At the same time, it can also effectively shield the seat cushion 4, preventing the surface temperature of the seat cushion 4 from becoming too high due to sun exposure, which would affect comfort. When it is in the folded state, it can form a box structure to effectively accommodate items.

[0047] This utility model has three major functions: storage, sun protection, and power generation. It is versatile and flexible in use.

[0048] Example 2:

[0049] Example 2 is based on Example 1:

[0050] like Figures 1 to 7 As shown, the solar-powered folding tail box includes a support assembly 3, which includes a rear shelf. The rear shelf is fixedly mounted on the electric vehicle frame and connected to the seat cushion 4. The rear shelf is located behind the seat cushion 4, and the foldable tail box body 1 is mounted on the rear shelf.

[0051] As an optional implementation, the solar cell module 2 includes an energy storage power supply 22, which is electrically connected to the solar panel module 21. The energy storage power supply 22 can be mounted on the rear rack via a fixed bracket or on the electric vehicle frame.

[0052] The energy storage power supply 22 uses a high-capacity lithium-ion battery with a built-in battery management system, which has at least the following advantages: high energy density, which can store more electrical energy in a smaller volume and weight; long cycle life, which can be charged and discharged many times and has a long service life; and high safety, which has overcharge, over-discharge, overcurrent, and short circuit protection functions to ensure safe use.

[0053] As an optional implementation, the solar cell module 2 also includes a charge controller 23, and the solar panel module 21 and the energy storage power supply 22 are both electrically connected to the charge controller 23.

[0054] The charging controller 23 is used to control the charging process of the solar panel module 21 to the energy storage power supply 22. When the charging controller 23 detects that the voltage and current meet the standards, it will send the converted electrical energy to the energy storage power supply 22, and the energy storage power supply 22 will store the electrical energy.

[0055] Specifically, the charging controller 23 uses an STM32 series microcontroller, which includes a voltage detection circuit, a current detection circuit, a control circuit, and a switching circuit. The voltage detection circuit monitors the voltage output by the solar panel module 21 in real time and converts the voltage signal into an electrical signal. The current detection circuit monitors the current output by the solar panel module 21 in real time and also converts the current signal into an electrical signal. The control circuit controls the switching circuit to open and close based on the electrical signals fed back by the voltage detection circuit and the current detection circuit. The switching circuit executes the connection and disconnection of the line between the solar panel module 21 and the energy storage power supply 22 according to the instructions of the control circuit. The charging controller 23 adopts existing technology, so the specific circuit diagrams of its parts will not be described in detail.

[0056] As an optional implementation, the solar cell module includes a voltage regulator 24, which is electrically connected to the energy storage power supply 22, and the electric vehicle circuit system is electrically connected to the voltage regulator 24.

[0057] The voltage regulator 24 is used to adjust the output voltage of the energy storage power supply 22 to the voltage of the electric vehicle auxiliary equipment, such as 12V or 24V, to ensure that the equipment works normally. When the electric vehicle needs power, the voltage regulator 24 delivers electrical energy to the electric vehicle circuit system.

[0058] Specifically, the voltage regulator 24 includes a step-down circuit, a voltage regulator circuit, and a protection circuit. The step-down circuit reduces the voltage output by the energy storage power supply 22 to the voltage range required by the electric vehicle circuit system. The voltage regulator circuit ensures that the voltage is stable at the set value to avoid damage to sensitive electronic components of the electric vehicle (such as the instrument panel and sensors) due to voltage fluctuations. The protection circuit has overcurrent, short circuit, and overvoltage protection functions. The voltage regulator 24 adopts existing technology, so the specific circuit diagrams of its parts will not be described in detail.

[0059] As an optional implementation, the foldable tail box body 1 includes a fixed bottom 11, a foldable body and a lid 13, and the solar panel module 21 includes multiple unit solar panels 211.

[0060] The fixed bottom 11 is fixedly mounted on the support assembly 3; the folding box panel includes a plurality of side boxes 12 mounted on the fixed bottom 11, two adjacent side boxes 12 are detachably connected by a connecting assembly, at least one side box panel 12 is configured as a folding box panel, the folding box panel is hinged to the fixed bottom 11, optionally, the hinge can be a one-way hinge, the folding box panel can only be flipped open to the outside of the box; the box cover 13 is rotatably connected to one of the folding box panels; a unit battery panel 211 is provided on the inner wall of at least one of the fixed bottom 11, the folding box panel and the box cover 13.

[0061] Specifically, the foldable tail box body 1 has a cubic structure, and the foldable box panel has four side panels 12.

[0062] Optionally, such as Figure 4 As shown, the fixed bottom 11 is the bottom box plate, and the four side box plates 12 are all folding box plates. The bottom edge of the folding box plate is hinged to the edge of the bottom box plate. The folding box plate located on the front side is hinged to the box cover 13. In this embodiment, all the box plates of the foldable tail box body 1 can be opened, which has a large solar energy collection area and a significant power generation effect.

[0063] Alternatively, such as Figure 5 As shown, the fixed bottom 11 is the bottom panel, and the two left and right side panels 12 of the four side panels 12 are fixed panels with their bottom edges fixedly connected to the corresponding edges of the bottom panel. The front side panel 12 of the four side panels 12 is a folding panel with its bottom edge hinged to the front edge of the bottom panel. The rear side panel 12 has its bottom edge detachably connected to the rear edge of the bottom panel via a magnetic assembly 5. The two sides of the lid 13 are hinged to the front side panel and the rear side panel, respectively. In this embodiment, since the front and rear side panels are connected to the two sides of the lid 13, when it is unfolded, all three unfold towards the front, providing a large covering area that can completely cover the seat cushion and provide significant sun protection.

[0064] Another option, such as Figure 6 As shown, the fixed bottom 11 is the lower box, which is an open-top box structure. The folding box is the upper box, and all its side panels 12 are folding panels. The lid 13 is hinged to the front side panel 12. In this embodiment, since the fixed bottom 11 is the lower box and the folding box is the upper box, it simultaneously has storage and power generation functions when all panels are unfolded. Furthermore, as... Figure 7As shown, when in the unfolded state, unit solar panels can be laid at the top opening of the fixed bottom 11 to further increase the power generation effect.

[0065] As an optional implementation, the solar panel is a flexible CIGS thin-film solar cell module, which has the advantages of high conversion efficiency, good flexibility, strong weather resistance and lightweight. It is fixed to the inner surface of the tail box panel with a special adhesive to ensure a firm connection and not affect the light-gathering effect of the solar panel.

[0066] As an optional implementation, the connecting component is configured as a magnetic suction component 5, and two adjacent side panels 12 are connected by magnetic suction component 5.

[0067] The magnetic component 5 uses a magnet, which is set at the edge of the corresponding box panel. It uses a magnetic connection method, which is firm and easy to assemble and disassemble.

[0068] As an optional implementation, the lid 13 is provided with a locking assembly 6 for locking the lid 13 to the closed state; the locking assembly 6 adopts an existing lock, and its detailed structure will not be described in detail.

[0069] As an optional implementation, the lid 13 is provided with a positioning insertion part, and the side panel 12 is provided with a positioning engagement part corresponding to the position of the positioning insertion part. The positioning engagement part and the positioning insertion part are shaped to fit together. When the lid 13 is in the closed state, the positioning insertion part and the positioning engagement part are engaged. The positioning engagement part and the positioning insertion part cooperate with each other to make the closed and folded states more stable.

[0070] Specifically, the folding case has positioning protrusions extending upward from the top of the side panels 12 on the rear, left, and right sides. The case cover 13 has positioning grooves corresponding to the positions of the positioning protrusions. When the case cover 13 is closed, the positioning protrusions are positioned and inserted into the positioning grooves, forming the positioning insertion part and the positioning grooves forming the positioning connection part.

[0071] As an optional implementation, the cover 13 is provided with a display screen for displaying illumination information and energy storage information.

[0072] In actual use, users can use the display screen to visually interact with the screen to determine whether the conditions for the tailgate to be opened are met, which further facilitates use; the display screen is existing technology and its structure will not be described in detail.
