Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a solar energy device and vehicle. Background Technology

[0002] With the continuous increase in global car ownership, the energy consumption and environmental pollution caused by traditional fuel vehicles are becoming increasingly serious. Developing new energy vehicles, especially electric vehicles, has become an inevitable trend in the transformation of the automotive industry. As a green and efficient energy replenishment method, vehicle-mounted solar power has broad application prospects, bringing energy-saving and replenishment benefits to car owners and reducing charging and electricity anxiety. To improve the utilization of roof space, existing vehicles are generally equipped with foldable solar panels; however, the folding and unfolding actions are complex and inconvenient to operate. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a solar energy device capable of unfolding and retracting solar panels, and which is simple and convenient to operate.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0057] Please refer to Figures 1-8 This application provides a solar energy device installed on the roof of a vehicle. The solar energy device has an deployed state and a retracted state. The solar energy device includes a first solar panel 100, a second solar panel 300, a third solar panel 400, a first linkage assembly 200, and a second linkage assembly 500. It should be noted that this application will show the solar energy device in an "deployed state" and a "retracted state," which refers to the final state and the initial state of the solar energy device. This application will also show the first solar panel 100, the second solar panel 300, or the third solar panel 400 being deployed and retracted. That is, when all movable parts are in the retracted state, the solar energy device is in the retracted state; when all movable parts are in the deployed state, the solar energy device is in the deployed state.

[0058] The first, second, and third solar panels can be crystalline silicon cells, thin-film cells, or perovskite cells. Among them, thin-film cells and perovskite cells can be lightweight and generate electricity in low light conditions, better meeting users' energy-saving needs for driving and their energy replenishment needs under different weather conditions.

[0059] Please refer to Figures 1-3 The first link assembly 200 is configured to swing relative to the first solar panel 100, and the second solar panel 300 is movably connected to the first link assembly 200, so that it can swing with the first link assembly 200 and move relative to the first solar panel 100.

[0060] The projection of the first solar panel 100 on the horizontal plane is called the first projection, and the projection of the second solar panel 300 on the horizontal plane is called the second projection. When the solar device is in the stored state, the first projection and the second projection at least partially overlap, that is, when the solar device is in the stored state, one of the first solar panel 100 and the second solar panel 300 is at least partially blocked by the other.

[0061] When the solar panel is in its deployed state, the first projection and the second projection are offset, meaning the first solar panel 100 and the second solar panel 300 do not obstruct each other. Alternatively, the first projection and the second projection partially overlap, and the overlapping area is smaller than the overlapping area when the solar panel is in its retracted state. In other words, in the deployed state, the overlapping area of ​​the first solar panel 100 and the second solar panel 300 is smaller than the overlapping area in the retracted state, allowing for better sunlight reception.

[0062] In the above embodiment, the solar energy device has an unfolded state and a retracted state. The second solar panel 300 is movably connected to the first linkage assembly 200 and can move relative to the first solar panel 100 by swinging the first linkage assembly 200. The projection of the first solar panel 100 on the horizontal plane is the first projection, and the projection of the second solar panel 300 on the horizontal plane is the second projection. The movement of the first solar panel 100 causes the position of its projection on the horizontal plane to change. When the solar energy device is in the retracted state, the first projection and the second projection at least partially overlap. When the solar energy device is in the unfolded state, the first projection and the second projection are offset or the overlapping area is reduced. Since the switching between the retracted and unfolded states is achieved by swinging the first linkage assembly 200, the operation is simple and convenient.

[0063] Please refer to Figure 1-5 In some embodiments, the second linkage assembly 500 is configured to oscillate relative to the first solar panel 100. The third solar panel 400 is movably connected to the second linkage assembly 500, thereby enabling it to move in sync with the oscillation of the second linkage assembly 500.

[0064] Please refer to the following: Figure 1 and Figure 4 The projection of the third solar panel 400 on the horizontal plane is the third projection. When the solar device is in the storage state, the second projection, the first projection, and the third projection at least partially overlap. That is, the projections of the second solar panel 300, the first solar panel 100, and the third solar panel 400 in the height direction at least partially overlap, thereby reducing the volume in the storage state.

[0065] When the solar panel is in the deployed state, the second projection, the first projection, and the third projection are arranged sequentially and staggered along the length of the vehicle, or the first projection, the second projection, and the third projection are arranged sequentially along the length of the vehicle, wherein any two adjacent projections overlap, and the overlapping area is smaller than the overlapping area of ​​the solar panel when it is in the retracted state.

[0066] It is important to understand that the sequential arrangement of the second, first, and third projections along the length of the vehicle indicates that, in the deployed state, the second solar panel 300 is located on one side of the first solar panel 100 along the length of the vehicle, and the third solar panel 400 is located on the opposite side of the first solar panel 100 along the length of the vehicle. Since there is space above the front and rear of the vehicle, these three solar panels can fully utilize this space without occupying space on either side of the vehicle, thus avoiding impacting surrounding vehicles in parking lots and similar environments. The staggered or overlapping areas of the second, first, and third projections along the length of the vehicle further increase the light-receiving area.

[0067] Please refer to Figure 1 and Figure 2 In some embodiments, when the solar energy device is in its retracted state, the second solar panel 300 is positioned above the first solar panel 100 and the third solar panel 400, and the sun-facing surface of the second solar panel 300 faces upwards in both the deployed and retracted states. The sun-facing surface of the second solar panel 300 is the side that receives sunlight to generate electricity. Whether in the deployed or retracted state, the second solar panel 300 can receive sunlight to generate electricity; even when the solar energy device is in its retracted state during vehicle operation, the second solar panel 300 can still generate electricity.

[0068] In both the unfolded and retracted states, the sun-facing side of the third solar panel 400 faces upwards.

[0069] In some embodiments, in the stowed state, the second solar panel 300 is located above the first solar panel 100 and the third solar panel 400, with the third solar panel 400 positioned above the first solar panel 100. Typically, the second solar panel 300 and the third solar panel 400 have different sizes, therefore requiring different spaces for stowage and movement. For example, as shown in the figure, the second solar panel 300 is larger and thus requires more space. In this embodiment, the second solar panel 300 and the third solar panel 400 are positioned on the same side of the first solar panel 100, allowing the third solar panel 400 to be stowed using the height space of the second solar panel 300 without requiring additional height space, thereby improving space utilization in the height direction.

[0070] Please refer to Figure 1 and Figure 2 In some embodiments, the first linkage assembly 200 includes a rocker arm movably connected to the second solar panel 300;

[0071] When the solar panel is in the deployed state, the rocker arm is tilted relative to the horizontal plane, and the end of the rocker arm connected to the second solar panel 300 is above the other end. That is, during the retraction process, a lateral force is applied to the second solar panel 300. This lateral force causes the first linkage assembly 200 to generate an upward component force and swing, thereby causing the second solar panel 300 to move in the opposite direction until it is retracted.

[0072] Compared to the case where, in the unfolded state, one end of the first link assembly 200 connecting to the second solar panel 300 is below the other end or at the same height, the second link assembly 200 can be folded up by simply pushing it to the side, without the need for lifting. This makes the operation much simpler.

[0073] Similarly, please refer to Figure 3 In some embodiments, the second linkage assembly 500 includes a rocker arm movably connected to the third solar panel 400. When the solar device is in the deployed state, the rocker arm is tilted relative to the horizontal plane, and one end of the rocker arm connected to the third solar panel 400 is above the other end.

[0074] Please refer to Figures 1-3 In some embodiments, the swing angle of the first link assembly 200 and the second link assembly 500 is less than 180°.

[0075] It is understandable that the first solar panel 100 can be relatively fixed, that is, the first solar panel 100 is relatively fixed whether the solar device is in the unfolded state or the retracted state.

[0076] However, in some embodiments, since the second solar panel 300 is in the unfolded state, one end of the first linkage assembly 200 connecting the second solar panel 300 is above the other end. This makes it impossible for the second solar panel 300 to move completely to the side of the first solar panel 100 when it is in the unfolded state. Therefore, the first solar panel 100 may be partially blocked, especially when the first solar panel 100 itself has a large dimension along the length of the vehicle, the above-mentioned blocking situation is more serious.

[0077] Please refer to the following for details. Figure 2 , Figure 3 and Figure 6 In some embodiments, the solar device includes a sliding component 600, which includes a fixed part 610 and a sliding part 620. The sliding part 620 is slidably engaged with the fixed part 610 and can slide relative to the fixed part 610. The first solar panel 100 is connected to the sliding part 620 and can slide along with the sliding part 620.

[0078] The solar energy device also includes an intermediate state between an unfolded state and a retracted state. When the solar energy device is in the intermediate state, the second solar panel 300 is unfolded and the first solar panel 100 remains retracted, with the first projection and the second projection partially overlapping. The first solar panel 100 is configured to slide relative to the fixed part 610 via the sliding part 620, so that the solar energy device switches from the intermediate state to the unfolded state.

[0079] It should be noted that the intermediate state lies between the unfolded state and the retracted state. This means that the solar panel can switch directly between these states, or it can switch to the intermediate state first, and then switch to either the retracted or unfolded state. For example, during the transition from the retracted to the unfolded state, if the second solar panel 300 is already unfolded while the first solar panel 100 remains retracted, this is the intermediate state. Further sliding and unfolding of the first solar panel 100 is required for the solar panel to reach the unfolded state.

[0080] In the above embodiments, the first solar panel 100 and the second solar panel 300 are deployed by swinging and sliding. Compared with swinging alone, the first solar panel 100 can be relatively larger in size along its sliding direction, thereby improving the utilization rate of the space above the vehicle.

[0081] Among them, reference Figure 2 The solar energy device includes a housing 710, a fixing part 610 fixed to the housing 710, the fixing part 610 can be a fixed track, the extension direction of which is the length direction of the vehicle, and a sliding part 620 is a slider that can slide along the track.

[0082] To facilitate the deployment of the third solar panel 400 and the first solar panel 100, in some embodiments, the second linkage assembly 500 is hinged to connect the third solar panel 400 and the first solar panel 100.

[0083] The third solar panel 400 is configured to be driven to move relative to the first solar panel 100 via the second linkage assembly 500, and to drive the first solar panel 100 to slide via the second linkage assembly 500, so that the solar device switches from an intermediate state to an unfolded state.

[0084] Specifically, under the external force acting on the third solar panel 400, the first solar panel 100, the second linkage assembly 500, and the third solar panel 400 slide as a whole, causing the first solar panel 100 to unfold. This force continues to act on the third solar panel 400, causing the second linkage assembly 500 to swing until the third solar panel 400 unfolds. During the retraction process, the external force acts in the opposite direction on the third solar panel 400, enabling both the first solar panel 100 and the third solar panel 400 to retract. This makes the unfolding and retraction operations more convenient.

[0085] Please refer to Figure 2 and Figure 3 In some embodiments, the first linkage assembly 200 includes a first rocker arm and a second rocker arm arranged sequentially along the length of the vehicle. The solar panel has the first rocker arm and the second rocker arm arranged on both sides along the width of the vehicle to ensure the stability of both sides of the second solar panel 300.

[0086] In this configuration, the lengths of the first rocker arm 210 and the second rocker arm 220 of the first linkage assembly 200 are either equal or unequal. It should be noted that when the lengths of the first rocker arm 210 and the second rocker arm 220 are equal, they form two rockers in a parallel four-bar linkage, allowing the second solar panel 300 to achieve translational motion during movement, i.e., without angular deflection. When the lengths of the first rocker arm 210 and the second rocker arm 220 of the first linkage assembly 200 are unequal, the angle of the second solar panel 300 in its deployed state will change to create a certain tilt angle, thereby adapting to latitude changes to face the direction of solar radiation and increasing peak solar power. Taking a region at 30° North latitude as an example, with a tilt angle of 30°, the maximum peak solar power can increase by 50% (on the winter solstice).

[0087] Similarly, in some embodiments, the second linkage assembly 500 includes a third rocker arm 510 and a fourth rocker arm 520 arranged sequentially along the length of the vehicle. The solar panel has the third rocker arm 510 and the fourth rocker arm 520 arranged on both sides along the width of the vehicle to ensure the stability of both sides of the third solar panel 400. The lengths of the third rocker arm 510 and the fourth rocker arm 520 of the second linkage assembly 500 are equal to allow the third solar panel 400 to translate; alternatively, the lengths of the third rocker arm 510 and the fourth rocker arm 520 of the second linkage assembly 500 are unequal to allow the third solar panel 400 to tilt at a certain angle.

[0088] Please refer to Figures 1-3 In some embodiments, the housing 710 has a storage cavity in which the first solar panel 100 and the third solar panel 400 can be stored. A first linkage assembly 200 hinges the second solar panel 300 and the housing 710. When the solar device is in the stored state, the second solar panel 300 closes the storage cavity of the housing 710, the first solar panel 100 is stored inside the housing 710, and the second solar panel 300 is configured to open the storage cavity by swinging relative to the housing 710 via the first linkage assembly 200. The third solar panel 400 can also be stored inside the housing 710.

[0089] Understandably, the second solar panel 300 functions as a cover, its structure including a top cover wall and side cover walls connected to the periphery of the top cover wall. The top cover wall is the solar panel, or the top cover wall includes a top cover plate and a solar panel, with the solar panel positioned above the top cover plate. Understandably, in its retracted state, the second solar panel 300 can still receive sunlight and generate electricity, thus not affecting its continued power generation during vehicle operation.

[0090] To reduce wind resistance during driving, in some embodiments, the top wall of the second solar panel 300 forms an arc transition surface 300a at the connection between the top wall and the side wall of the cover, so that when air flows through it, it can flow more smoothly along the arc transition surface 300a.

[0091] In some embodiments, a seal 740 is provided between the second solar panel 300 and the housing 710. The seal 740 achieves a seal through its own deformation, thereby reducing the possibility of rainwater intrusion or other foreign object intrusion under weather conditions such as rain and wind. The seal 740 is annular and surrounds the contact surface between the second solar panel 300 and the housing 710. The cross-section of the seal 740 can be rectangular; please refer to [reference needed]. Figure 10 The seal 740 can also be multiple connected trapezoids, with the top and bottom surfaces of each trapezoid contacting the housing 710 and the second solar panel 300, respectively. Please refer to [reference needed]. Figure 9The seal 740 can also be multiple connected semicircles, with the top and bottom surfaces of each semicircle contacting the housing 710 and the second solar panel 300, respectively. The aforementioned multiple trapezoidal or semicircular seals 740 have multiple spaced-apart sealing surfaces, thereby improving the sealing effect. Please refer to [reference needed]. Figure 8 In other embodiments, the contact surface of the second solar panel 300 with the housing 710 is L-shaped, the contact surface of the housing 710 with the second solar panel 300 is also L-shaped, and the cross-section of the seal 740 is L-shaped to improve the sealing effect.

[0092] For ease of use, please refer to the following: Figure 2 and Figure 5 In some embodiments, a handle 750 is provided on the second solar panel 300, and the handle 750 is located on one side of the length direction of the second solar panel 300. Similarly, in some embodiments, a handle 750 is provided on the third solar panel 400, and the handle 750 is located on one side of the length direction of the cover 720.

[0093] Please refer to Figure 2 In some embodiments, the solar device further includes at least one set of damping elements 730. The set of damping elements 730 connects the housing 710 and the second solar panel 300 to provide damping force to slow down the swing speed of the cover 720, thereby reducing the impact force when the housing 710 and the cover 720 come together.

[0094] The damping component 730 can be a pneumatic damping component, a hydraulic damping component, a friction damping component, or a spring.

[0095] Similarly, in some embodiments, a set of damping elements 730 connects the first solar panel 100 and the third solar panel 400 to provide damping force to slow down the swing speed of the third solar panel 400, thereby reducing the impact force during storage.

[0096] Please refer to Figure 7 In some embodiments, the solar device further includes at least one set of limiting members 760, which are used to limit the extreme positions of the swing of the first link assembly 200 or the second link assembly 500.

[0097] A set of limiting members 760 is disposed on the housing 710. The limiting member 760 can be a limiting pin, and the cross-section of the limiting member 760 can be polygonal, circular, or semi-circular. The first rocker arm 210 or the second rocker arm 220 of the first linkage assembly 200 can be provided with a corresponding notch, the shape of which is adapted to the shape of the limiting member 760.

[0098] A set of limiting members 760 is disposed on the outer peripheral frame of the first solar panel 100. The first rocker arm 210 or the second rocker arm 220 of the second linkage assembly 500 may be provided with corresponding notches.

[0099] In some embodiments, the storage cavity is divided into a first region and a second region, with the first solar panel 100 and the third solar panel 400 both located in the first region. The solar device also includes a solar controller 770, a wiring harness, and a charging gun. The wiring harness connects the solar controller 770 and the charging gun, and the charging gun can be moved out of the storage cavity to discharge externally. The solar controller 770, wiring harness, and charging gun are all located in the second region, thereby improving space utilization and device integration. Please refer to [reference needed]. Figure 11 The first solar panel 100, the second solar panel 300, and the third solar panel 400 are electrically connected to the solar controller 770. The solar controller 770 is electrically connected to the vehicle body 20 or other electrical devices. The solar controller 770 can control the first solar panel 100, the second solar panel 300, and the third solar panel 400 to charge the battery of the vehicle body 20 or discharge other electrical devices.

[0100] Alternatively, the wiring harness can be connected to a charging terminal instead of a charging gun. The charging terminal is connected to the vehicle's low-voltage bus (12V) to supply power to the vehicle's low-voltage bus.

[0101] In some embodiments, the deployment process of the solar energy device is as follows:

[0102] Pulling the handle 750 on the second solar panel 300 towards the front along the length of the vehicle causes the first linkage assembly 200 to swing, and the second solar panel 300 to move and unfold, at which point the solar device is in the middle state.

[0103] Pulling the handle 750 on the third solar panel 400 towards the rear along the length of the vehicle causes the sliding assembly 600 and the second linkage assembly 500 to operate. The first solar panel 100 and the third solar panel 400 slide to their limit positions, and the second linkage assembly 500 swings, thereby causing the first solar panel 100 and the third solar panel 400 to move and unfold. At this time, the solar device is in the unfolded state.

[0104] Remove the charging gun and wiring harness to charge vehicles or other electrical devices.

[0105] In some embodiments, the storage process for the solar energy device is as follows:

[0106] The charging gun and wiring harness are stored in the receiving cavity.

[0107] Pushing the third solar panel handle 750 towards the front of the vehicle along its length causes the sliding assembly 600 and the second linkage assembly 500 to operate, moving and retracting the first solar panel 100 and the third solar panel 400, placing the solar device in an intermediate state.

[0108] Pushing the handle 750 on the second solar panel 300 toward the rear of the vehicle along its length causes the first linkage assembly 200 to swing, the second solar panel 300 to move and retract, and the solar device to be in a retracted state.

[0109] This application also provides a vehicle, including a vehicle body 20 and a solar energy device, with a luggage rack on the top of the vehicle body and the solar energy device mounted on the luggage rack.
