[0007] Optionally, when the rain curtain is in a folded state, the active ribs and at least one driven rib are stacked in a first direction in the mounting seat; the matching piece is provided on a side of the driven rib close to the active rib along the first direction; During the unfolding of the rain curtain, the active rib rotates in the direction away from the fixed side of the rain curtain, and the cooperation between the main drive component and the matching component drives the adjacent driven rib to rotate in the direction away from the fixed side of the rain curtain; during the folding of the rain curtain, the active rib rotates in the direction close to the fixed side of the rain curtain, and the cooperation between the main drive component and the matching component drives the adjacent driven rib to rotate in the direction close to the fixed side of the rain curtain; When the rain curtain is in an expanded state, the active fan ribs and at least one of the driven fan ribs are spaced apart from each other along the expansion direction of the rain curtain.

[0008] When the rain curtain is folded, the active ribs and at least one driven rib are stacked in a first direction within the mounting base, reducing the space occupied by the folding assembly. When the rain curtain is unfolded, the active ribs and at least one driven rib are spaced apart along the unfolding direction of the rain curtain, maximizing the unfolded area of ​​the rain curtain and ensuring uniform support for the active ribs and all driven ribs.

[0009] Optionally, the folding fan further comprises a rotating shaft, the rotating shaft being rotatably connected to the mounting seat, one end of the active fan bone being fixed to the rotating shaft, and one end of the driven fan bone being rotatably connected to the rotating shaft around the axis of the rotating shaft; the folding fan driving mechanism comprises a folding fan driving member and a folding fan transmission member, the folding fan transmission member being transmission-connected between the output end of the folding fan driving member and the rotating shaft, and the folding fan driving member drives the rotating shaft to rotate via the folding fan transmission member; or, It also includes a rotating shaft, which is fixedly connected to the mounting seat, one end of the active fan bone is rotatably connected to the rotating shaft around the axis of the rotating shaft, and one end of the driven fan bone is rotatably connected to the rotating shaft around the axis of the rotating shaft; the folding fan driving mechanism includes a folding fan driving member and a folding fan transmission member, the folding fan transmission member is transmission-connected between the output end of the folding fan driving member and the active fan bone, and the folding fan driving member drives the active fan bone to rotate through the folding fan transmission member.

[0010] A rotating shaft is provided to rotatably connect one end of the active fan rib and one end of the driven fan rib to the mounting seat, so that the active fan rib and the driven fan rib rotate more smoothly.

[0011] In one embodiment, the rotating shaft is rotatably connected to the mounting seat, the active fan ribs are fixed to the rotating shaft, and the driven fan ribs are rotatably connected to the rotating shaft.

[0014] Optionally, a through hole is provided at one end of the driven fan bone, and the rotating shaft is passed through the through hole; Along the first direction where the rotation axis of the active fan bone is located, an annular spacer is provided between the active fan bone and the driven fan bone and / or between adjacent driven fan bones, and the annular spacer is loosely sleeved on the rotation axis.

[0015] By setting an annular gasket, the spacing between one end of the active fan bone and one end of the driven fan bone and / or between one end of the adjacent driven fan bone can be ensured, so that support can be formed between one end of the active fan bone and one end of the driven fan bone and / or between one end of the adjacent driven fan bone. At the same time, the cooperation between the main driving part of the active fan bone and the matching part of the driven fan bone also forms a support, so that the active fan bone and the driven fan bone form support at two places, ensuring that the gap between the active fan bone and the driven fan bone and the gap between the adjacent driven fan bones will not change significantly, thereby ensuring that the unfolding and folding process of the entire rain curtain structure can proceed smoothly.

[0016] Optionally, the mounting base includes a base plate, a first guide member is provided on the side of the base plate facing the folding fan assembly, the active fan bone is closer to the base plate than the driven fan bone, and a second guide member is provided on the side of the active fan bone facing the base plate, the first guide member and the second guide member are slidably matched to guide the rotation of the active fan bone.

[0021] One end of the guide chute is closed to form a closed end. When the guide slider contacts the closed end of the guide chute, it stops sliding, preventing the guide slider from falling out of the guide chute from the one end of the guide chute. This limits the maximum rotation angle of the active fan rib and prevents damage to the rain curtain from excessive pulling. If the other end of the guide chute is closed, the active fan rib can be positioned in the initial position during installation. If the other end of the guide chute is open, the guide slider can be installed from the open end of the guide chute, making installation easier.

The larger the expansion angle of the rain curtain, the larger the expansion area of ​​the rain curtain and the better the rain shelter effect.

[0042] The folding fan drive mechanism is installed at one end of the mounting seat in the length direction, that is, the folding fan drive mechanism is offset. In this way, the maximum expansion angle of the rain curtain can reach 90 degrees. While ensuring that the expansion area of ​​the rain curtain is larger, the mounting seat can be set shorter, which is more conducive to the arrangement of the rain curtain structure on the vehicle.

[0050] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0051] See also Figures 1 to 12 The present invention provides a rain curtain structure, including a mounting seat 1, a folding fan drive mechanism 2 and a folding fan assembly 3, the folding fan assembly 3 including a rain curtain 31, an active fan bone 32 and at least one driven fan bone 33, the mounting seat 1 is suitable for being installed or integrally formed on the roof of a vehicle, the rain curtain 31 has a relative fixed side and a movable side, the fixed side of the rain curtain 31 is fixed to the mounting seat 1, the movable side of the rain curtain 31 is fixed to the active fan bone 32, and the driven fan bone 33 is fixed to the rain curtain 31.

[0052] The active fan rib 32 is provided with a main drive component 321, and the driven fan rib 33 is provided with a matching component 331. The folding fan drive mechanism 2 can drive the active fan rib 32 to rotate, so as to drive the driven fan rib 33 to rotate through the cooperation between the main drive component 321 and the matching component 331, thereby unfolding or folding the rain curtain 31.

[0053] When the rain curtain 31 is in a folded state, the folding fan assembly 3 is accommodated in the mounting seat 1 ; when the rain curtain 31 is in an unfolded state, the folding fan assembly 3 is exposed from the mounting seat 1 .

[0054] In the rain curtain structure of the embodiment of the present application, the folding fan drive mechanism 2 can drive the active rib 32 to rotate, so as to drive the driven rib 33 to rotate through the cooperation of the main drive component 321 on the active rib 32 and the matching component 331 on the driven rib 33, thereby unfolding or folding the rain curtain 31. In this way, on rainy days, when passengers get on the bus, after opening the door, the active rib 32 and the driven rib 33 are rotated out of the mounting seat 1 in turn, the folding fan assembly 3 is exposed from the mounting seat, the rain curtain 31 is unfolded, and the passengers put away their umbrellas under the rain curtain 31 and then enter the bus, so that the passengers will not be wetted by the rain when getting on the bus. After the passengers get on the bus, they close the door, the driven rib 33 and the active rib 32 are rotated into the mounting seat 1 in turn, the folding fan assembly 3 returns to the mounting seat 1, and the rain curtain 31 is folded. On rainy days, when a passenger gets off the bus, they first open the door, and the active ribs 32 and the driven ribs 33 are sequentially rotated out of the mounting seat 1, the folding fan assembly 3 is exposed from the mounting seat, and the rain curtain 31 is unfolded. After the passenger steps out of the door, they open the umbrella under the rain curtain 31, and the passenger is protected from the rain when getting off the bus. In other words, the rain curtain structure of the embodiment of the present application can solve the problem of passengers being easily wetted by rain when getting on and off the bus.

[0055] In addition, the cooperation between the main driving part of the active fan bone 32 and the matching parts of the driven fan bone 33 can not only constrain the rotation of the active fan bone 32 and the driven fan bone 33, but also form a lever between the main driving part 321 and the rotating axis of the active fan bone 32 to prevent the folding fan assembly 3 from sinking under the action of its own weight when the rain curtain 31 is unfolded.

[0056] The rain curtain 31 can be made of curtain cloth, plastic or elastic rubber sheet.

[0057] The active ribs 32 are made of a material with good rigidity to ensure effective vertical support for the remaining driven ribs 33. The active ribs 32 are, for example, hollow extruded aluminum alloy parts.

[0058] In one embodiment, mounting base 1 is adapted to be mounted on the roof of a vehicle, i.e., mounting base 1 is disposed independently of the vehicle's roof. Preferably, mounting base 1 is secured to the underside of the vehicle's roof by bolts or the like and located inside the vehicle door. This allows the entire rain screen structure to be concealed within the vehicle when the door is closed, without interfering with the door's opening or closing. Furthermore, fixedly connecting mounting base 1 to the vehicle's roof offers greater design flexibility than integrating mounting base 1 into the roof, as the vehicle body structure does not require modification, making the rain screen structure provided by the present embodiment highly versatile.

[0059] In one embodiment, see Figure 4 and Figure 10 When the rain curtain 31 is in the folded state, the active ribs 32 and at least one driven rib 33 are stacked in the mounting base 1 along a first direction; the fitting 331 is provided on a side of the driven rib 33 close to the active rib 32 along the first direction. The first direction is preferably the height direction of the vehicle.

[0060] During the unfolding process of the rain curtain 31, the active fan rib 32 rotates in the direction away from the fixed side of the rain curtain 31, and the cooperation between the main drive component 321 and the matching component 331 drives the adjacent driven fan rib 33 to rotate in the direction away from the fixed side of the rain curtain 31; during the folding process of the rain curtain 31, the active fan rib 32 rotates in the direction close to the fixed side of the rain curtain 31, and the cooperation between the main drive component 321 and the matching component 331 drives the adjacent driven fan rib 33 to rotate in the direction close to the fixed side of the rain curtain 31.

[0061] When the rain curtain 31 is in the expanded state, the active ribs 32 and the at least one driven rib 33 are spaced apart from each other along the expansion direction of the rain curtain 31 .

[0062] When the rain curtain 31 is in the folded state, the active ribs 32 and at least one driven rib 33 are stacked in the first direction in the mounting base 1, which can reduce the space occupied by the folding assembly 3. When the rain curtain 31 is in the unfolded state, the active ribs 32 and at least one driven rib 33 are spaced apart from each other along the unfolding direction of the rain curtain 31, so that the unfolded area of ​​the rain curtain 31 is as large as possible, and the active ribs 32 and all the driven ribs 33 can evenly support the rain curtain 31.

[0063] In one embodiment, see Figure 4 、 Figure 5 and Figure 9 , also includes a rotating shaft 4, which is rotatably connected to the mounting base 1, one end of the active fan bone 32 is fixed to the rotating shaft 4, and one end of the driven fan bone 33 is rotatably connected to the rotating shaft 4 around the axis of the rotating shaft 4.

[0064] A rotating shaft 4 is provided to rotatably connect one end of the active rib 32 and one end of the passive rib 33 to the mounting base 1, thereby ensuring smoother rotation of the active rib 32 and the passive rib 33. The rotating shaft 4 is rotatably connected to the mounting base 1, the active rib 32 is fixed to the rotating shaft 4, and the passive rib 33 is rotatably connected to the rotating shaft 4. The active rib 32 rotates synchronously with the rotating shaft 4, and the passive rib 33 rotates with the rotation of the active rib 32, thereby ensuring more stable rotation of the active rib 32.

[0065] In one embodiment, see Figure 4 、 Figure 5 The two ends of the rotating shaft 4 are rotatably connected to the mounting base 1, and the rotating shaft 4 rotates stably and is not prone to deflection.

[0066] In one embodiment, see Figure 6 and Figure 9 The folding fan driving mechanism 2 includes a folding fan driving member 21 and a folding fan transmission member 22. The folding fan transmission member 22 is connected between the output end of the folding fan driving member 31 and the rotating shaft 4. The folding fan driving member 31 drives the rotating shaft 4 to rotate through the folding fan transmission member 32.

[0067] The folding fan transmission member 32 can achieve the deceleration and torque-increasing effect from the folding fan driving member 31 to the rotating shaft 4.

[0068] In one embodiment, see Figure 6 and Figure 9 The folding fan driving component 31 includes a folding fan motor 211, which is installed on the mounting base 1. The folding fan transmission component 32 includes a first gear 221 and a second gear 222. The first gear 221 is connected to the output end of the folding fan motor 211, and the second gear 222 is fixed or integrally formed on the rotating shaft 4. The folding fan motor 211 can drive the first gear 221 to rotate, so as to drive the rotating shaft 4 to rotate through the engagement of the first gear 221 and the second gear 222.

[0069] The folding fan motor 211 drives the first gear 221 to rotate, so as to drive the rotating shaft 4 to rotate through the engagement between the first gear 221 and the second gear 222. The folding fan transmission member 32 has a simple structure and good reliability.

[0070] In another embodiment, a rotating shaft 4 is further included, which is fixedly connected to the mounting base 1. One end of the active rib 32 is rotatably connected to the rotating shaft 4 around the axis of the rotating shaft 4, and one end of the passive rib 33 is rotatably connected to the rotating shaft 4 around the axis of the rotating shaft 4. The rotating shaft 4 is provided to rotatably connect one end of the active rib 32 and one end of the passive rib 33 to the mounting base 1, so that the active rib 32 and the passive rib 33 rotate more smoothly. The rotating shaft 4 is fixedly connected to the mounting base 1, and the active rib 32 and the passive rib 33 are rotatably connected to the rotating shaft 4. The active rib 32 rotates relative to the rotating shaft 4. The rotating shaft 4 does not need to be fixedly connected to the active rib 32, which makes assembly simpler and prevents the rotating shaft 4 from wearing out and failing.

[0071] Corresponding to the embodiment in which the rotating shaft 4 is fixedly connected to the mounting base 1, the folding fan driving mechanism 2 includes a folding fan driving member 21 and a folding fan transmission member 22. The folding fan transmission member 22 is transmission-connected between the output end of the folding fan driving member 21 and the active fan bone 32. The folding fan driving member 21 drives the active fan bone 33 to rotate through the folding fan transmission member 22.

[0072] Corresponding to the embodiment in which the rotating shaft 4 is fixedly connected to the mounting base 1, the folding fan driving component 21 includes a folding fan motor 211, the folding fan motor 211 is installed on the mounting base 1, and the folding fan transmission component 22 includes a first gear 221 and a second gear 222. The first gear 221 is connected to the output end of the folding fan motor 211, and the second gear 222 is fixed or integrally formed at one end of the active fan bone 32. The folding fan motor 211 can drive the first gear 221 to rotate, so as to drive the active fan bone 21 to rotate through the engagement of the first gear 221 and the second gear 222.

[0073] In one embodiment, see Figure 10 A through hole 332 is provided at one end of the driven fan bone 33, and the rotating shaft 4 is passed through the through hole 332.

[0074] Along the first direction of the rotation axis of the active fan bone 32 (the axial direction of the rotating shaft 4), an annular gasket (not shown in the figure) is arranged between the active fan bone 32 and the driven fan bone 33 and / or between adjacent driven fan bones 33, and the annular gasket is loosely mounted on the rotating shaft 4.

[0075] By setting an annular gasket, the spacing between one end of the active fan bone 32 and one end of the driven fan bone 33 and / or between one end of the adjacent driven fan bone 32 can be ensured, so that support can be formed between one end of the active fan bone 32 and one end of the driven fan bone 33 and / or between one end of the adjacent driven fan bone 33. At the same time, the main driving part 321 of the active fan bone 32 and the matching part 331 of the driven fan bone 33 also form a support, so that the active fan bone 32 and the driven fan bone 33 form support at two places, ensuring that the gap between the active fan bone 32 and the driven fan bone 33 and the gap between the adjacent driven fan bones 33 will not change significantly, thereby ensuring that the unfolding and folding process of the entire rain curtain structure can proceed smoothly.

[0076] In one embodiment, the annular spacer between the active fan bone 32 and the driven fan bone 33 is integrally formed on the driven fan bone 33. In this way, during assembly, the annular spacer and the driven fan bone 33 are assembled to the rotating shaft 4 as a whole, which makes assembly simpler.

[0077] In another embodiment, the annular spacer between the active fan bone 32 and the driven fan bone 33 is fixed to the driven fan bone 33. In this way, during assembly, the annular spacer and the driven fan bone 331 are fixedly assembled and rotatably assembled to the rotating shaft 4 as a whole, which makes assembly simpler.

[0078] Of course, in other embodiments, the annular spacer between the active rib 32 and the driven rib 33 may be independent of the active rib 32 and the driven rib 33. In this way, the structural complexity of the driven rib 33 can be reduced.

[0079] In one embodiment, the annular spacer between adjacent driven ribs 33 is integrally formed on one of the driven ribs 33. In this way, during assembly, the annular spacer and the driven rib 33 are rotatably assembled to the rotating shaft 4 as a whole, which makes assembly simpler.

[0080] In another embodiment, the annular spacer between adjacent driven ribs 33 is separated from the two adjacent driven ribs 33. In this way, the structural complexity of the driven ribs 33 can be reduced.

[0081] In one embodiment, see Figure 4 、 Figure 7 and Figure 9 The mounting base 1 includes a base plate 11, and a first guide member 111 is provided on the side of the base plate 11 facing the folding fan assembly 3. The active fan bone 32 is closer to the base plate 11 than the driven fan bone 33. The active fan bone 32 is provided on the side facing the base plate 11 with a second guide member 322. The first guide member 111 and the second guide member 322 are slidably matched to guide the rotation of the active fan bone 32.

[0082] The first guide member 111 and the second guide member 322 slide together to constrain the rotation of the active fan rib 32. At the same time, a lever is formed between the second guide member 322 and the rotation axis (rotating axis 4) of the active fan rib 32 to prevent the folding fan assembly 3 from sinking under the action of its own weight when the rain curtain 31 is unfolded.

[0083] In one embodiment, see Figure 4 、 Figure 7 and Figure 9 The first guide member 111 is a guide rail 1111 , and the second guide member is a guide slider 3221 .

[0084] The guide rail 1111 is provided with a guide slot 1112 , which is in an arc shape, and the center of the guide slot 1112 is on the rotation axis of the active fan bone 32 (the axis of the rotating shaft 4 ).

[0085] The guide slider 3221 and the guide rail 1111 have a simple structure and stable cooperation, which can well constrain the rotation of the active fan rib 32. The guide groove 1112 is arc-shaped, and the center of the guide groove 1112 is on the rotation axis of the active fan rib 32, ensuring that the active fan rib 32 rotates smoothly without getting stuck.

[0086] In one embodiment, see Figure 4 、 Figure 7 and Figure 9 One end of the guide groove 1112 in the length direction is closed to form a closed end, and the other end of the guide groove 1112 in the length direction is open. The guide slider 3221 stops sliding when it contacts the closed end of the guide groove 1112 to limit the maximum rotation angle of the active fan bone 32.

[0087] One end of the guide slot 1112 is closed to form a closed end. When the guide slider 3221 contacts the closed end of the guide slot 1112, it stops sliding. This prevents the guide slider 3221 from slipping out of the guide slot 1112 from the one end of the guide slot 1112. This limits the maximum rotation angle of the active rib 32 and prevents the rain curtain 32 from being damaged by excessive pulling. The other end of the guide slot 1112 is open, allowing the guide slider 3221 to be installed from the open end of the guide slot 1112, making installation easier.

[0088] In one embodiment, the guide slider 3221 includes a slide rod portion 32211 and a slide plate portion 32212, the cross-sectional area of ​​the slide plate portion 32212 is larger than the cross-sectional area of ​​the slide rod portion 32211, the guide groove 1112 is stepped, and the guide groove 1112 has a first groove and a second groove, the first groove exposes the top surface of the guide rail 1111, the width of the first groove is smaller than the width of the second groove, the slide rod portion 32212 slides in the second groove, and the slide rod portion 32211 slides in the first groove and passes through the first groove.

[0089] In this way, the active rib 32 can be prevented from being separated from the mounting seat 1 .

[0090] In another embodiment, the first guide member 111 may be a guide slider 3221 , and the second guide member may be a guide rail 1111 .

[0091] In one embodiment, see Figure 5 、 Figure 9 and Figure 10 The main driving component 321 is a driving rail 3211 , and the matching component 331 is a driving slider 3311 .

[0092] The driving slide rail 3211 is provided with a driving slide groove 32111 , which is arc-shaped, and the center of the driving slide groove 32111 is on the rotation axis of the active fan bone 32 .

[0093] The drive slider 3311 and the drive rail 3211 have a simple structure and stable cooperation, which can effectively constrain the rotation of the active fan rib 32 and the driven fan rib 33. The drive chute 32111 is arc-shaped, and the center of the drive chute 32111 is on the rotation axis of the active fan rib 32, ensuring that the active fan rib 32 and the driven fan rib 33 rotate smoothly without getting stuck.

[0094] In one embodiment, see Figure 9 The two ends of the driving slide groove 32111 in the length direction are closed to limit the movement stroke of the driving slider 3311.

[0095] Both ends of the driving slide groove 32111 in the length direction are closed, so that the driving slider 3311 will not fall out of the driving slide groove 32111 along the length direction of the driving slide groove 32111, thereby preventing the rain curtain 31 from being damaged by excessive pulling.

[0096] In one embodiment, see Figure 4 、 Figure 5 、 Figure 10 The driven fan bone 33 is provided with multiple, the matching piece 331 is provided on the side of the driven fan bone 33 close to the active fan bone 32, and the side of the driven fan bone 33 away from the active fan bone 32 is provided with a driven piece 333.

[0097] During the unfolding process of the rain curtain 31, the active fan rib 32 rotates toward the direction away from the fixed side of the rain curtain 31, and the cooperation between the main driving component 321 and the matching component 331 drives the adjacent driven fan rib 33 to rotate toward the direction away from the fixed side of the rain curtain 31. Through the cooperation between the driven component 333 and the matching component 331 between adjacent driven fan ribs 33, multiple driven fan ribs 33 can be rotated in the direction away from the fixed side of the rain curtain 31 in turn; during the folding process of the rain curtain 31, the active fan rib 32 rotates toward the direction close to the fixed side of the rain curtain 31, and the cooperation between the main driving component 321 and the matching component 331 drives the adjacent driven fan rib 33 to rotate toward the fixed side of the rain curtain 31. Through the cooperation between the driven component 333 and the matching component 331 between adjacent driven fan ribs 33, multiple driven fan ribs 32 rotate in the direction close to the fixed side of the rain curtain 31 in turn.

[0098] A plurality of driven fan bones 33 are provided to better unfold and support the rain curtain 31, so that after the rain curtain 31 is fully unfolded, multiple supports are formed along its unfolding direction, thereby preventing the rain curtain 31 from sagging under its own weight and affecting passengers getting on and off the vehicle and taking shelter from the rain.

[0099] In the embodiment with multiple driven ribs 33, see Figure 4 、 Figure 5 When the rain curtain 31 is in the folded state, the active fan ribs 32 and the multiple driven fan ribs 33 are stacked in the mounting seat 1 along the first direction.

[0100] When the rain curtain 31 is in the expanded state, the active ribs 32 and the plurality of driven ribs 33 are spaced apart from each other along the expansion direction of the rain curtain 31 .

[0101] When the rain curtain 31 is in the folded state, the active ribs 32 and all the driven ribs 33 are stacked in the first direction in the mounting base 1, which can reduce the space occupied by the folding assembly 3. When the rain curtain 31 is in the unfolded state, the active ribs 32 and all the driven ribs 33 are spaced apart from each other along the unfolding direction of the rain curtain 31, so that the unfolded area of ​​the rain curtain 31 is as large as possible, and the active ribs 32 and all the driven ribs 33 can evenly support the rain curtain 31.

[0102] In one embodiment, see Figure 4 、 Figure 5 、 Figure 6 The mounting base 1 includes a base plate 11 and a cover plate 12. The cover plate 12 is connected to the base plate 11 to form a receiving chamber 5 therebetween. Preferably, the fixed side of the rain curtain 31 is fixed to the cover plate 12. One end of the rotating shaft 4 is rotatably connected to the base plate 11, and the other end is rotatably connected to the cover plate 12.

[0103] When the rain curtain 31 is in the folded state, the folding fan assembly 3 is accommodated in the accommodating cavity 5 ; when the rain curtain 31 is in the unfolded state, the folding fan assembly 3 can be exposed from the accommodating cavity 5 through the external opening of the accommodating cavity 5 .

[0104] A receiving cavity 5 is formed between the bottom plate 11 and the cover plate 12. When the rain curtain 31 is in the folded state, the folding fan assembly 3 is accommodated in the receiving cavity 5, preventing the folding fan assembly 3 from being exposed, improving the appearance, and not occupying the external space of the mounting base 1. The folding fan assembly 3 can be exposed from the receiving cavity 5 through the external opening of the receiving cavity 5, so that the rain curtain 31 can be smoothly unfolded.

[0105] However, in other embodiments, the cover plate 12 may be omitted.

[0106] In one embodiment, see Figure 1 、 Figure 2 、 Figure 6 、 Figure 8 The mounting base 1 further includes a support plate 13 and a flip cover 14. The support plate 13 is fixed to the base plate 11. The flip cover 14 is rotatably connected to the support plate 13. The flip cover 14 can rotate between a first position and a second position.

[0107] When the flip cover 14 is in the first position (see Figure 1 ), the flip cover 14 covers the external opening of the accommodating chamber 5; when the flip cover 14 is in the second position (see Figure 2 ), the flip cover 14 exposes the external opening of the accommodating cavity 5 to allow the folding fan assembly 3 to expose the accommodating cavity 5.

[0108] A flip cover 14 is provided to close the external opening of the accommodating cavity 5. When the rain curtain 31 is in the folded state, the folding fan assembly 3 in the accommodating cavity 5 can be shielded, making it more beautiful. Moreover, the flip cover 14 can play a waterproof and dustproof role when closed.

[0109] In one embodiment, see Figure 6 、 Figure 11 、 Figure 12 , further comprising a flip driving mechanism 6, which can drive the flip cover 14 to rotate.

[0110] Compared with manually rotating the flip cover 14, the flip driving mechanism 6 is provided to automatically rotate the flip cover, saving manpower.

[0111] Of course, the flip driving mechanism 6 may be eliminated and the flip cover 14 may be manually rotated, which is more cost-effective.

[0112] In one embodiment, see Figure 11 、 Figure 12 The flip driving mechanism 6 includes a flip driving member 61 and a flip transmission member 62. The flip transmission member 62 is connected between the output end of the flip driving member 61 and the flip cover 14. The flip driving member 61 drives the flip cover 14 to rotate through the flip transmission member 62.

[0113] The flip transmission member 62 can achieve a deceleration and torque-increasing effect from the flip driving member 61 to the flip cover 14 .

[0114] In one embodiment, see Figure 11 、 Figure 12 The flip driving member 61 includes a flip motor 611, and the flip transmission member 62 includes a third gear 621, a fourth gear 622 and a fifth gear 623. The flip motor 611 is installed on the support plate 13, the third gear 621 is connected to the output end of the flip motor 611, the fourth gear 622 is rotatably connected to the support plate 1, and the fifth gear 623 is fixed or integrally formed on the flip cover 14. The fourth gear 622 is engaged between the third gear 621 and the fifth gear 623. The flip motor 611 can drive the third gear 621 to rotate, so as to drive the flip cover 14 to rotate through the fourth gear 622 and the fifth gear 623.

[0115] The flip motor 611 drives the third gear 621 to rotate, thereby driving the flip cover 14 to rotate via the fourth gear 622 and the fifth gear 623. The flip transmission member 622 has a simple structure and good reliability.

[0116] In one embodiment, see Figure 8 、 Figure 11 、 Figure 12 The support plate 1 is provided with a first mounting portion 15 and a second mounting portion 16 relative to each other, and the flip driving mechanism 6 is provided on the first mounting portion 15 .

[0117] One end of the flip cover 14 in the longitudinal direction is rotatably connected to the first mounting portion 15 , and the other end of the flip cover 14 in the longitudinal direction is rotatably connected to the second mounting portion 16 .

[0118] One end of the flip cover 14 in the length direction is rotatably connected to the first mounting portion 15 of the support plate 1, and the other end of the flip cover 14 in the length direction is rotatably connected to the second mounting portion 16 of the support plate 1. The first mounting portion 15 and the second mounting portion 16 are opposite to each other along the length direction of the flip cover 14. In this way, both ends of the flip cover 14 in the length direction form a rotational connection, and the rotation of the flip cover 14 is more stable.

[0119] In one embodiment, see Figure 8 、 Figure 11 、 Figure 12 A first guide groove 151 is provided on the first mounting portion 15, and a first guide shaft 141 is provided at one end in the longitudinal direction of the flip cover 14. The first guide shaft 141 passes through the first guide groove 151. The first guide groove 151 is arc-shaped, and the center of the first guide groove 151 is on the rotation axis of the flip cover 14.

[0120] A second guide groove 161 is provided on the second mounting portion 16, and a second guide shaft (not shown in the figure) is provided at the other end of the flip cover 14 in the longitudinal direction. The second guide shaft passes through the second guide groove 161. The second guide groove 161 is arc-shaped, and the center of the second guide groove 161 is on the rotation axis of the flip cover 14. The radius of the first guide groove 151 is equal to that of the second guide groove 161.

[0121] The first guide shaft 141 on the flip cover 14 slidably engages with the first guide groove 151 on the first mounting portion 15. The first guide groove 151 is arc-shaped, with its center centered on the rotation axis of the flip cover 14. The second guide shaft on the flip cover 14 slidably engages with the second guide groove 161 on the second mounting portion 16. The second guide groove 161 is arc-shaped, with its center centered on the rotation axis of the flip cover 14. This ensures smooth rotation of the flip cover 14. The sliding engagement between the first guide shaft 141 and the first guide groove 151, and the sliding engagement between the second guide shaft and the second guide groove 161, guides the rotation of the flip cover 14 and prevents it from getting stuck.

[0122] In one embodiment, see Figure 8 、 Figure 11 、 Figure 12 The first mounting portion 15 is a box-shaped structure, and the flip driving mechanism 6 is arranged in the first mounting portion 15, which is more beautiful and can protect the flip driving mechanism 6.

[0123] However, in other embodiments, the flip driving mechanism 6 may also be arranged outside the first mounting portion 15. In this way, the installation is simpler.

[0124] exist Figure 1-12 In the illustrated embodiment, the folding fan drive mechanism 2 is mounted at one end of the mounting base 1 in the longitudinal direction, that is, the folding fan drive mechanism 2 is offset. At this time, the first gear 221 and the second gear 222 are arranged in the accommodating chamber 5. The folding fan motor 211 is arranged outside the accommodating chamber 5, for example, on the outer surface of the bottom plate 11. Of course, if the space in the accommodating chamber 5 allows, the folding fan motor 211 can also be arranged in the accommodating chamber 5. The maximum unfolding angle of the rain curtain 31 is 90 degrees. The maximum unfolding angle refers to the maximum angle that can be unfolded, that is, the angle between the fixed side and the movable side of the rain curtain 31 relative to each other when the rain curtain 31 is in the unfolded state. The folding fan drive mechanism 2 is mounted at one end of the mounting base 1 in the longitudinal direction, that is, the folding fan drive mechanism 2 is offset. In this way, the maximum unfolding angle of the rain curtain 31 can reach 90 degrees. While ensuring that the unfolding area of ​​the rain curtain 31 is relatively large, the mounting base 1 can be set shorter, which is more conducive to the arrangement of the rain curtain structure on the vehicle.

[0125] See also Figure 13 and Figure 14In another embodiment, the folding fan driving mechanism 2 is installed in the middle position in the length direction of the mounting base 1, that is, the folding fan driving mechanism 2 is arranged in the center, so that the maximum expansion angle of the rain curtain 31 can reach 180 degrees. The larger the expansion angle of the rain curtain 31, the larger the expansion area of ​​the rain curtain 31, and the better the rain shelter effect.

[0126] exist Figure 13 and Figure 14 In the illustrated embodiment, the flip driving mechanism 6 is disposed outside the first mounting portion 15 , so that the flip driving mechanism 6 is easier to install.

[0127] exist Figure 13 and Figure 14 In the illustrated embodiment, the folding fan motor 211, the first gear 221, and the second gear 222 are all disposed outside the mounting base 1 (eg, on the outer surface of the bottom plate 11). This makes the flip drive mechanism 6 easier to install.

[0128] The number of fan ribs (the sum of the number of active fan ribs 32 and the number of driven fan ribs 33) is designed according to the space requirements. The design principle is that the maximum width of a single fan blade in the expanded state is a<(Y-6)mm, where Y is the width of the accommodating cavity 5. The fan blade calculation formula is: a=2R*sin(Z / x); wherein R is the maximum radius of the rain curtain 31 , x is the sum of the number of active ribs 32 and driven ribs 33 , and Z is the maximum deployment angle of the rain curtain 31 .

[0129] When the maximum width a of the fan blade, the maximum radius of the rain curtain 31, and the maximum expansion angle Z of the rain curtain 31 are determined, the sum x of the number of active fan bones 32 and the number of driven fan bones 33 can be calculated according to the above formula. The number of active fan bones 32 is 1, and the number of driven fan bones is x-1.

[0130] In this way, the formula can accurately obtain the sum x of the number of active ribs 32 and driven ribs 33, avoiding too few ribs reducing the supporting strength of the rain curtain 31, and also avoiding too many ribs increasing the weight of the folding fan assembly 3.

[0131] In the embodiment with the folding fan motor 211, the folding fan controller and the folding fan motor 211 are combined into one, that is, the folding fan controller is integrated into the folding fan motor 211. The folding fan controller is used to control the operation of the folding fan motor 211. Here, the operation of the folding fan motor 211 includes starting, stopping, forward rotation (unfolding the rain curtain 31), and reverse rotation (folding the rain curtain 31) of the folding fan motor 211.

[0132] In the embodiment having the flip motor 611, the flip motor 611 is integrated with a flip controller. The flip controller is used to control the operation of the flip motor 611. Here, the operation of the flip motor 611 includes starting, stopping, forward rotation (opening the flip cover 14), and reverse rotation (closing the flip cover 14).

[0133] On the other hand, an embodiment of the present application provides a rain curtain system, including a rainfall detection device, a door opening and closing sensor, and the rain curtain structure of the above embodiment.

[0134] When the rainfall detection device detects that the rainfall is greater than 0 and the door opening and closing sensor detects that the door is in an open state, the folding fan drive mechanism 2 can drive the active fan rib 32 to rotate in the direction away from the fixed side of the rain curtain 31, so as to drive the driven fan rib 33 to rotate through the cooperation of the main drive component 321 and the matching component 331, thereby unfolding the rain curtain 31.

[0135] When the rain curtain 31 is in the unfolded state, when the door opening and closing sensor detects that the door is in the closed state, the folding fan drive mechanism 2 can drive the active fan rib 32 to rotate toward the fixed side close to the rain curtain 31, so as to drive the driven fan rib 33 to rotate through the cooperation of the main drive component 321 and the matching component 331, thereby folding the rain curtain 31.

[0136] In one embodiment, a folding fan controller is further included, which is integrated into the folding fan driving mechanism 2 or is independent of the folding fan driving mechanism 2; the folding fan controller can control the operation of the folding fan driving mechanism 2.

[0137] The controller can control the operation of the folding fan driving mechanism 2 to drive the active fan ribs 32 to rotate or not to drive the active fan ribs 32 to rotate. The rotation direction of the active fan ribs 32 can also be controlled by the controller.

[0138] In one embodiment, the rain detection device is disposed at the front of the vehicle, and the rain detection device and the rain sensor for the wiper are the same component or different components.

[0139] Based on the rainfall detected by the rain detection device, it is determined whether the rain curtain system needs to be started. When the rainfall detected by the rain detection device is 0, the action of opening and closing the car door will not trigger the start of the rain curtain system. In the rain curtain system of the embodiment of the present application, on rainy days, when the passenger gets on the car, after opening the car door, the rain detection device detects that the rainfall is greater than 0 and the car door opening and closing sensor detects that the car door is in the open state, the folding fan drive mechanism 1 drives the active fan bone 21 to rotate in the direction away from the fixed side of the rain curtain 2, so as to drive the driven fan bone 33 to rotate through the cooperation of the main drive component 321 and the matching component 331, the active fan bone 32 and the driven fan bone 33 are rotated out of the mounting seat 1 in turn, the folding fan assembly 3 is exposed from the mounting seat 1, the rain curtain 31 is unfolded, and the passenger puts away the umbrella under the rain curtain 31 and then enters the car, so that the passenger will not be wet by the rain when getting on the car. After the passengers get on the bus and close the door, the door opening and closing sensor detects that the door is in the closed state, and the folding fan drive mechanism 2 drives the active fan rib 32 to rotate toward the fixed side close to the rain curtain 31, so as to drive the driven fan rib 33 to rotate through the cooperation of the main drive component 321 and the matching component 331. The driven fan rib 33 and the active fan rib 32 are successively transferred to the mounting seat 1, and the folding fan assembly 3 returns to the mounting seat 1 to fold the rain curtain 31. On rainy days, when a passenger gets off the bus, they first open the door. The rainfall detection device detects that the rainfall is greater than 0 and the door opening and closing sensor detects that the door is open. The folding fan drive mechanism 2 drives the active fan rib 32 to rotate in a direction away from the fixed side of the rain curtain 321, so that the driven fan rib 33 can rotate through the cooperation between the main drive component 321 and the matching component 331. The active fan rib 32 and the driven fan rib 33 are rotated out of the mounting seat 1 in turn, and the folding fan assembly 3 is exposed from the mounting seat 1, unfolding the rain curtain 31. After the passenger steps out of the door, he or she can open an umbrella under the rain curtain 31. The passenger will not get wet when getting off the bus. That is, the rain curtain system of the embodiment of the present application can solve the problem of passengers being easily wetted by rain when getting on and off the bus.
