Description

Technical Field

[0001] The utility model relates to the technical field of recreational vehicles, in particular to a trailer recreational vehicle and a vehicle. Background Art

[0002] In the related art, a solar panel is installed on the roof of the trailer caravan. The solar panel converts light energy into electrical energy and stores it in the trailer caravan's energy storage battery for use by the trailer caravan's electrical appliances. On the one hand, the solar panel will increase wind resistance when the trailer caravan is moving. On the other hand, after long-term use, the surface of the solar panel needs to be cleaned to ensure power generation efficiency. When the solar panel fails, it also needs to be replaced or repaired. However, because the solar panel is fixed on the top of the car, it is inconvenient to clean and maintain it. In some cases, when the solar panel is not in use, it is also necessary to carry the solar panel with you, resulting in a large wind resistance in the trailer caravan. Utility Model Content

[0053] See also Figures 1 to 3 A trailer RV 100 provided in an embodiment of the utility model includes a carriage 10, a solar panel 20, an electromagnet 31 and a magnetically absorbable component 32. The electromagnet 31 is arranged on the carriage 10, and the magnetically absorbable component 32 is arranged on the solar panel 20. The solar panel 20 is detachably mounted on the carriage 10 through the magnetic attraction between the electromagnet 31 and the magnetically absorbable component 32.

[0054] In the above-mentioned trailer RV 100, the solar panel 20 is detachably mounted on the car body 10 through the magnetic attraction between the magnetically absorbable part 32 and the electromagnet 31. Therefore, when the solar panel 20 needs to be removed (the electromagnet 31 is powered off or not during removal), the solar panel 20 is directly removed from the car body 10, which is beneficial to the maintenance and cleaning of the solar panel 20 and reducing the wind resistance of the trailer RV 100. When installing the solar panel 20, the electromagnet 31 can be energized, and the solar panel 20 can be installed on the car body 10 by aligning the magnetically absorbable part 32 with the electromagnet 31.

[0055] Specifically, the utility model does not specifically limit the installation position of the electromagnet 31 . Optionally, the electromagnet 31 can be arranged on the inner side of the top of the carriage 10 , and the solar panel 20 can be installed on the outer side of the top of the carriage 10 .

[0056] When the solar panel 20 is needed, the solar panel 20 is fixed on the top of the car body 10 through the cooperation of the electromagnet 31 and the magnetically absorbable part 32. When the solar panel 20 is not needed, the solar panel 20 can be removed and placed in the car body 10 or other places. This allows the trailer RV 100 to adapt to different usage scenarios.

[0057] The trailer RV 100 includes an energy storage battery 15 and a control component, the control component is electrically connected to the energy storage battery 15 and the electromagnet 31, and the control component can use the electric energy of the energy storage battery 15 to power the electromagnet. Optionally, the control component can be installed inside the vehicle 10, and the energy storage battery 15 can be installed on the chassis of the vehicle.

[0058] The magnetically adsorbable component 32 may be an element that can be adsorbed by magnetic force. Optionally, the magnetically adsorbable component 32 includes but is not limited to magnetic components and structural components made of materials that can be adsorbed by magnetic components (such as iron). Magnetic components include but are not limited to permanent magnets, electromagnets, etc., which are not specifically limited here. Optionally, the magnetically adsorbable component 32 may be a structural component of the solar panel 20 itself, or a structural component of other structures (such as a frame) connected to the solar panel 20 itself, which is not specifically limited in the present invention.

[0059] Optionally, the magnetically adsorbable part 32 may be a magnetic part. When the solar panel 20 is disassembled and placed inside the vehicle compartment 10, the magnetic part arranged on the solar panel 20 may be adsorbed to the side wall of the vehicle compartment 10 for accommodating the solar panel 20. In this way, the solar panel 20 may be stably fixed and protected.

[0060] In some embodiments, the trailer 100 may be used in the following scenarios:

[0061] When the solar panel 20 fails, is damaged, needs to be cleaned or is not in use, the electromagnet can be powered off to eliminate the magnetic force of the electromagnet, and the solar panel 20 can be directly removed from the carriage 10 without removing the fixings used to fix the solar panel 20, which facilitates the maintenance, repair, cleaning or storage of the solar panel 20.

[0062] When the trailer RV 100 needs to move, the electromagnet 31 can be powered off, and the solar panel 20 can be removed and placed in the car body 10 before moving. This can reduce the wind resistance of the trailer RV 100 during movement. When the solar panel 20 is needed, it can be installed on the car body 10.

[0063] Optionally, installation marks, such as convex dots, spray-painted patterns, etc., can be set on both the carriage 10 and the solar panel 20 to indicate the alignment position of the solar panel 20 and the carriage 10. The position of the installation mark on the carriage 10 corresponds to the position of the electromagnet 31, and the position of the installation mark on the solar panel 20 corresponds to the position of the magnetically adsorbable part 32, so that the user can install the solar panel 20 conveniently.

[0064] See also Figures 2 to 5 In some embodiments, a frame 21 is provided around the outer edge of the solar panel 20, and the frame 21 includes a frame bar 213, and a receiving space is provided in the frame bar 213, and the magnetically absorbable component 32 is located in the receiving space. In this way, the magnetically absorbable component 32 is protected.

[0065] Specifically, a frame 21 is arranged around the solar panel 20, and the frame 21 facilitates the connection between the solar panel 20 and the car body. The magnetically adsorbable component 32 is arranged in the accommodating space of the frame strip 213 to prevent the magnetically adsorbable component 32 from being exposed and causing damage to the magnetically adsorbable component 32 due to erosion by moisture, dust, etc., thereby improving the service life of the magnetically adsorbable component 32.

[0066] When the magnetically absorbable member 32 can be provided in plurality, each magnetically absorbable member 32 can be provided in a strip shape (eg Figure 4 as shown) or dot array settings (as Figure 2 As shown), specifically, each border strip 213 may have a storage space, and a magnetically adsorbable component 32 may be disposed in the storage space; when only one magnetically adsorbable component 32 is disposed, the magnetically adsorbable component 32 may be disposed in a ring shape, and the storage spaces of all border strips 213 may be connected to form a whole cavity, and the magnetically adsorbable component 32 may be disposed in the storage space.

[0067] exist Figure 4 In the embodiment, the frame 21 is rectangular and has four border strips 213. It is understood that in other embodiments, the frame 21 may also be in other shapes, not limited to a rectangle, and the utility model does not make specific limitations on this. The electromagnet 31 may also be provided as one or more.

[0068] In some embodiments, the trailer 100 includes a plurality of electromagnets 31 and a plurality of magnetically absorbable components 32 , and the plurality of electromagnets 31 and the plurality of magnetically absorbable components 32 can be absorbed in a one-to-one correspondence.

[0069] In some embodiments, the trailer caravan 100 includes a control component, which is electrically connected to the electromagnet 31 , and the control component is configured to control the magnitude and / or direction of the current flowing through the electromagnet 31 .

[0070] Thereby, the convenience of disassembling and assembling the solar panel 20 can be further improved.

[0071] Specifically, in one embodiment, when the solar panel 20 needs to be installed, the control component can first control the electromagnet 31 to be energized, and the user then aligns the magnetically absorbable part 32 of the solar panel 20 with the electromagnet 31, so that the electromagnet 31 generates a magnetic attraction force on the magnetically absorbable part 32, so that the solar panel 20 is installed on the car 10, or the user first aligns the magnetically absorbable part 32 of the solar panel 20 with the electromagnet 31, and the control component then controls the electromagnet 31 to be energized, so that the electromagnet 31 generates a magnetic attraction force on the magnetically absorbable part 32, so that the solar panel 20 is installed on the car 10.

[0072] When the solar panel 20 needs to be removed, the control component can control the electromagnet 31 to be powered off (the current is zero), and the magnetic attraction of the electromagnet 31 to the magnetically absorbable part 32 disappears or weakens, so that the user can easily remove the solar panel 20 from the car 10.

[0073] In one embodiment, when the solar panel 20 needs to be installed, the control component can first control the electromagnet 31 to pass a first direction current, and the user can align the magnetically absorbable part 32 of the solar panel 20 with the electromagnet 31, so that the electromagnet 31 passing the first direction current generates a magnetic attraction force on the magnetically absorbable part 32, so that the solar panel 20 is installed on the carriage 10, or the user first aligns the magnetically absorbable part 32 of the solar panel 20 with the electromagnet 31, and the control component then controls the electromagnet 31 to pass a first direction current, so that the electromagnet 31 passing the first direction current generates a magnetic attraction force on the magnetically absorbable part 32, so that the solar panel 20 is installed on the carriage 10.

[0074] When the solar panel 20 needs to be removed, the control component can control the electromagnet 31 to pass current in the second direction. The electromagnet 31 can generate a magnetic repulsive force on the magnetically adsorbable part 32, so that the user can easily remove the solar panel 20 from the car 10. The first direction is opposite to the second direction.

[0075] It can be understood that the magnetic attraction of the electromagnet 31 is changed by controlling the current of the electromagnet 31. When removing the solar panel 20, the control component can control the current of the electromagnet 31 to decrease, so that the magnetic attraction of the electromagnet 31 is reduced. At this time, the solar panel 20 is still installed on the car 10, but because the magnetic attraction of the car 10 to the solar panel 20 is reduced, it is convenient for the user to remove the solar panel 20. This situation can also prevent the magnetic attraction of the electromagnet 31 from disappearing after the electromagnet 31 is powered off, and cause the solar panel 20 to move unexpectedly when the user is not ready to remove the solar panel 20. This movement may cause the solar panel 20 to fall and be damaged, or press on the user.

[0076] The control component controls whether the electromagnet 31 is powered on or off or the current direction changes, which can be achieved by the user pressing a corresponding button in the carriage 10, and the utility model does not make specific limitations on this.

[0077] In one embodiment, the trailer RV 100 includes a permanent magnet 33 disposed on the vehicle body 10, and the solar panel 20 is detachably mounted on the vehicle body 10 through the magnetic attraction between the permanent magnet 33 and the magnetically adsorbable component 32, and the magnetic attraction of the permanent magnet 30 on the magnetically adsorbable component 32 is smaller than the magnetic attraction of the electromagnet 31 on the magnetically adsorbable component 32 when power is supplied to the electromagnet 31.

[0078] Thereby, the magnetic attraction force can be adjusted.

[0079] Specifically, when the electromagnet 31 is powered off, the magnetic attraction of the electromagnet 31 disappears or weakens, and the magnetic attraction of the permanent magnet 33 to the magnetically absorbable part 32 remains substantially unchanged. Therefore, the magnetic attraction of the car 10 to the solar panel 20 is reduced. At this time, the solar panel 20 is still installed on the car 10, but since the magnetic attraction of the car 10 to the solar panel 20 is reduced, it is convenient for the user to dismantle the solar panel 20. This situation can also prevent the magnetic attraction of the electromagnet 31 from disappearing after the electromagnet 31 is powered off, and cause the solar panel 20 to move unexpectedly when the user is not ready to dismantle the solar panel 20. This movement may cause the solar panel 20 to fall and be damaged, or press on the user.

[0080] like Figure 1 , Figures 6 to 8 As shown, in some embodiments, the carriage 10 includes a body 12, a first body 11 and a second body 13, the first body 11 and the second body 13 are slidably connected to both sides of the body 12 along the width direction; the carriage 10 has an expanded state and a stored state; in the stored state, the first body 11 and the second body 13 are accommodated in the body 12; in the expanded state, the first body 11 and the second body 13 protrude relative to the body 12. In this way, the trailer RV 100 is easy to move.

[0081] Optionally, in Figure 1 In the embodiment, the main body 12, the first body 11 and the second body 13 can all be in the shape of a rectangular parallelepiped. Figure 1 or Figure 6 In the left-right direction shown, along the width direction of the carriage 10, the first carriage 11 can be slidably connected to the left side of the body 12, and the second carriage 13 can be slidably connected to the right side of the body 12. The first carriage 11 and the second carriage 13 can be manually and / or electrically switched to enable the trailer 100 to switch between the storage state and the expansion state.

[0082] When changing from the expanded state to the stored state, the first compartment 11 and the second compartment 13 can be driven manually and / or electrically to move toward the main body 12 so that the first compartment 11 and the second compartment 13 are accommodated in the main body 12 .

[0083] When changing from the storage state to the expanded state, the first box 11 and the second box 13 can also be driven manually and / or electrically to move in a direction away from the main body 12, so that the first box 11 and the second box 13 protrude relative to the main body 12, and then a part of the first box 11 is connected to the left side close to the main body 12, and another part of the first box 11 is protruded outside the main body 12, and a part of the second box 13 is connected to the right side close to the main body 12, and another part of the second box 13 is protruded outside the main body 12.

[0084] The electric unfolding method can drive the movement of the first box 11 and the second box 13 by setting a driving component. Specifically, the driving component may include a motor, a gear, a first rack and a second rack; the gear is connected to the output shaft of the motor, the first rack is connected to the first box 11 and the gear, and the second rack is connected to the second box 13 and the gear. When the motor rotates, it drives the gear to rotate, and then drives the first rack and the second rack to move. In this process, the movement directions of the first rack and the second rack are opposite. When the motor rotates, the first box 11 and the second box 13 move towards or away from the main body 12 at the same time.

[0085] Optionally, when the motor drives the gear to rotate clockwise, the first rack can drive the first body 11 to move away from the body 12, and the second rack can drive the second body 13 to move away from the body 12, so that the carriage 10 can be switched from the storage state to the expansion state. When the motor drives the gear to rotate counterclockwise, the first rack can drive the first body 11 to move toward the body 12, and the second rack can drive the second body 13 to move toward the body 12, so that the carriage 10 can be switched from the expansion state to the storage state.

[0086] It is understood that the structure of the driving assembly is not limited to the above structure, and may also be other structures, which are not specifically limited here. The movement of the first body 11 and the second body 13 may also be at different times, which are not specifically limited here.

[0087] When manually opened, the trailer caravan 100 is unfolded by manually pulling the first car body 11 and the second car body 13 to move, and the trailer caravan 100 is stored by pushing the first car body 11 and the second car body 13 to move.

[0088] The solar panel 20 includes a first solar panel 23 , a second solar panel 24 and a third solar panel 25 . The first solar panel 23 is fixed on the top of the body 12 , the second solar panel 24 is arranged on the top of the first compartment 11 , and the third solar panel 25 is arranged on the top of the second compartment 13 .

[0089] The second solar panel 24 and the third solar panel 25 both include a first panel 26 and a second panel 27, the second panel 27 is movably connected to the first panel 26, the first panel 26 of the second solar panel 24 is fixed to the top of the first compartment 11, and the first panel 26 of the third solar panel 25 is fixed to the top of the first compartment 11. The first panel 26 and the second panel 27 are capable of converting light energy into electrical energy.

[0090] The second solar panel 24 and the third solar panel 25 both have a folded state and an unfolded state. In the folded state, the second panel 27 is stacked on the first panel 26. In the unfolded state, the second panel 27 is unfolded relative to the first panel 26.

[0091] The manner in which the second plate 27 is movably connected to the first plate 26 may include, but is not limited to, a sliding connection, a planar rotation connection, and a flip connection.

[0092] When in the unfolded state, the solar panel 20 can provide more illumination area, thereby increasing the amount of power generated.

[0093] like Figure 7 As shown, in some embodiments, a ladder 40 is provided on the rear side of the body 12. In this way, the installation and removal of the solar panel 20 are facilitated.

[0094] Please combine Figure 6 and Figure 7 The ladder 40 facilitates the user to install the solar panel 20 on the top of the first compartment 11, the top of the second compartment 13 and the top of the main body 12, and facilitates the removal of the solar panel 20 from the top of the first compartment 11, the top of the second compartment 13 and the top of the main body 12.
