Description

Technical Field

[0001] This invention belongs to the technical field of automotive sunshade devices, specifically relating to a retractable vehicle-mounted sunshade device. Background Technology

[0002] Summer temperatures are high, and without sunshades, vehicles parked for extended periods are exposed to continuous sunlight, causing the interior temperature to rise steadily and eventually exceed the outside temperature. When the vehicle is in use, this high temperature inside can cause discomfort for the driver and passengers. Therefore, some have proposed using awnings to shield vehicles and lower the interior temperature; however, most existing awnings require installation in open areas and are complex and time-consuming to set up and take down. To simplify setup and takedown, patent application number 2013206647340 discloses a vehicle-mounted sunshade that uses a frame to install the sunshade fabric on the roof. However, the sunshade fabric always covers the roof, taking up roof space and posing a safety hazard while the vehicle is in motion. Summary of the Invention

[0003] The purpose of this invention is to provide a retractable vehicle-mounted sunshade device that is easy to retract and store, allowing the canopy to be stored in a storage box to ensure vehicle driving safety.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A vehicle-mounted retractable sunshade device includes a storage box with a telescopic sunshade mechanism inside. The telescopic sunshade mechanism includes a vertical support rod, one end of which is hinged to the bottom of the storage box. An automatic telescopic rod is hinged to the vertical support rod, and the end of the automatic telescopic rod away from the vertical support rod is hinged to the bottom of the storage box. The rotation axis of the automatic telescopic rod is parallel to that of the vertical support rod. A longitudinal telescopic component is connected to the end of the vertical support rod away from the storage box. The longitudinal telescopic component is connected to a canopy and is used to longitudinally extend and retract the canopy.

[0005] Furthermore, the vertical support rod includes an outer telescopic rod with one end hinged to the storage box, and an inner telescopic rod that is slidably connected to the outer telescopic rod along its length direction. The inner telescopic rod is slidably arranged along the length direction of the outer telescopic rod. The inner telescopic rod is hinged to the automatic telescopic rod and connected to the longitudinal telescopic assembly.

[0006] Furthermore, the storage box includes a box body and a pair of hinged opening and closing covers. The rotation axis of the opening and closing covers is perpendicular to the rotation axis of the outer telescopic rod. Each opening and closing cover is connected to the outer telescopic rod by a cover guide rod. The two ends of the cover guide rod are omnidirectionally connected to the outer telescopic rod and the opening and closing cover, respectively.

[0007] Furthermore, the longitudinal telescopic assembly includes a main transverse slide rail connected to one end of the inner telescopic rod away from the bottom of the housing. A pair of active sliders are slidably connected on the main transverse slide rail. Each active slider is connected to the outer telescopic rod by a slider transmission rod. The two ends of each slider transmission rod are hinged to the active slider and the outer telescopic rod, respectively, or can be universally rotatably connected. The active slider is connected to a scissor-type telescopic frame, which includes multiple pairs of scissor rods. The active slider is hinged to a pair of scissor rods in the scissor-type telescopic frame.

[0008] Furthermore, the longitudinal telescopic component is connected to the transverse telescopic component, which is connected to the canopy surface. The transverse telescopic component includes two horizontal umbrella rib mechanisms connected to both ends of the main transverse slide rail. The horizontal umbrella rib mechanism includes a multi-fold umbrella rib structure and a vertical umbrella rib structure connected to the multi-fold umbrella rib structure. The multi-fold umbrella rib structure includes an upper and lower end umbrella rib located at the end away from the main transverse slide rail. The vertical umbrella rib structure includes a short rod hinged to the end of the upper end umbrella rib away from the main transverse slide rail. An inner umbrella rib and two short rods are hinged to the end of the short rod away from the upper end umbrella rib. The short pole is hinged to the lower umbrella rib at the end; an outer umbrella rib is hinged to the end of the lower umbrella rib away from the main transverse guide rail, and the outer umbrella rib and the two short poles are hinged together; two inner umbrella ribs are hinged to the end of the outer umbrella rib away from the lower umbrella rib at the end; three and four short poles are hinged to the end of the inner umbrella rib away from the short pole; the end of the three short poles away from the inner umbrella rib is hinged to the outer umbrella rib at the end; the end of the four short poles away from the inner umbrella rib is hinged to the two inner umbrella ribs at the end; three vertical umbrella ribs are hinged to the end of the two inner umbrella ribs away from the outer umbrella rib at the end; two outer umbrella ribs are hinged between the three vertical umbrella ribs and the outer umbrella rib. The lower umbrella rib, the one short pole, the two short poles, and the one outer umbrella rib form a convex quadrilateral structure; the three short poles, the four short poles, the two inner umbrella ribs, and the one outer umbrella rib form a concave quadrilateral structure.

[0009] Furthermore, the multi-fold umbrella rib structure includes a section of umbrella rib hinged to the outer telescopic rod, and a second section of umbrella rib and a passive transmission rod hinged to the end of the section of umbrella rib away from the outer telescopic rod; the end of the passive transmission rod away from the first section of umbrella rib is hinged to the active slider; an upper umbrella rib is hinged to the end of the second section of umbrella rib away from the first section of umbrella rib, and one end of the upper umbrella rib is hinged to the main transverse slide rail.

[0010] Furthermore, the lateral telescopic assembly also includes secondary lateral slide rails parallel to the main lateral slide rail. Each secondary lateral slide rail has a pair of passive sliders slidably connected to it, and each pair of passive sliders is hinged to a pair of shear bars. Each secondary lateral slide rail has a vertical rod connected to its middle section, and each vertical rod is connected to a pair of adjacent upper shear bars by a pair of support guide rods. The pair of support guide rods connected to the vertical rod are located between the vertical rod and the vertical support rod. The two ends of each support guide rod are omnidirectionally rotatably connected to the vertical rod and the shear bars, respectively. Each secondary lateral slide rail has a horizontal support umbrella rib mechanism connected to both ends. The passive transmission rod and an outer umbrella rib of the horizontal support umbrella rib mechanism connected to the secondary lateral slide rail are hinged to the passive sliders and the secondary lateral slide rail, respectively.

[0011] Furthermore, a power supply and control circuit board is installed inside the box, and a suction cup connected to it is installed at the bottom of the box.

[0012] Furthermore, the outer telescopic rod is connected to a pair of sliding support rods. One end of each sliding support rod is universally connected to the outer telescopic rod, and the other end is slidably connected to the shearing rod connected to the active slider, providing support for the shearing rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. A vertical support rod and an automatic telescopic rod are installed in the storage box. The vertical support rod can be retracted and extended, allowing the telescopic rod to rotate to a vertical position and extend, thereby driving the longitudinal telescopic components and the canopy to retract and extend. This reduces the longitudinal space occupied on the roof and allows the telescopic sunshade mechanism to be stored in the storage box, ensuring vehicle driving safety. An opening and closing cover can seal the box, ensuring the stability of the telescopic sunshade mechanism inside. Furthermore, the opening and closing of the cover is driven by the outer telescopic rod and the cover transmission rod, eliminating the need for an additional drive structure.

[0014] 2. The longitudinal telescopic component is set as a scissor-type telescopic frame. Only one pair of scissor rods needs to be driven to drive the entire telescopic frame to extend or retract, which is convenient to drive. The automatic telescopic rod drives the inner telescopic rod to extend, which in turn drives the active slider to slide, so that the scissor-type telescopic frame can extend or retract. Vertical extension and longitudinal extension can be achieved through one automatic telescopic rod, making the structure simpler. The symmetrical slider transmission rod can ensure that the scissor-type telescopic frame extends or retracts symmetrically about the middle, ensuring stable extension and retraction.

[0015] 3. The horizontal telescopic component enables the canopy to expand and contract laterally, increasing the area when the canopy is open and improving the shading effect. The vertical umbrella rib structure enables the canopy to expand vertically, allowing it to cover the windows on both sides of the vehicle. A support guide rod is installed between the shear bar and the secondary horizontal slide rail, connecting to the vertical rod. This allows the secondary horizontal slide rail to be supported by the shear bar, thus ensuring the stable expansion and contraction of the horizontal umbrella rib mechanism connected to the secondary horizontal slide rail by the passive slider.

The bottom end of the inner telescopic rod 8 is set in the groove, and the bottom end of the inner telescopic rod 8 is hinged to the automatic telescopic rod 5 with the rotation axis set laterally. The inner telescopic rod 8 is connected to the longitudinal telescopic component.

[0020] The storage box includes a box body 1 and a pair of hinged opening and closing covers 2. The two opening and closing covers 2 are symmetrical from left to right. When closed, the opening and closing covers 2 form the left and right sides, the top surface, and the front surface of the storage box. The rotation axis of the opening and closing covers 2 is set horizontally and longitudinally. Each opening and closing cover 2 is connected to an outer telescopic rod 3 by a cover guide rod 11. The two ends of the cover guide rod 11 are omnidirectionally connected to the outer telescopic rod 3 and the opening and closing cover 2, respectively. A power supply and control circuit board is installed inside the box body 1. A suction cup is fixedly connected to the bottom of the box body 1 for connecting to the top of the vehicle.

[0021] like Figure 2-3 As shown, the longitudinal telescopic assembly includes a main transverse slide rail 6 fixedly connected to the top of the inner telescopic rod 8 in the middle. The main transverse slide rail 6 is arranged transversely, and a pair of active sliders 7 are slidably connected on the main transverse slide rail 6.

The transverse telescopic component includes two horizontal support umbrella rib mechanisms 13 connected to both ends of the main transverse slide rail 6. Each horizontal support umbrella rib mechanism 13 includes a multi-fold umbrella rib structure and a vertical umbrella rib structure connected to the multi-fold umbrella rib structure. The multi-fold umbrella rib structure can be replaced by existing technology. The multi-fold umbrella rib structure is a four-fold umbrella rib, and the vertical umbrella rib structure is a three-fold umbrella rib.

[0023] Each multi-fold umbrella rib structure includes a section of umbrella rib 16 hinged to the top of the outer telescopic rod 3. At the end of the section of umbrella rib 16 furthest from the outer telescopic rod 3, two sections of umbrella rib 17 and a passive transmission rod 18 are hinged. At the end of the passive transmission rod 18 furthest from the section of umbrella rib 16, an active slider 7 is hinged. At the end of the two sections of umbrella rib 17 furthest from the section of umbrella rib 16, an upper umbrella rib 14 is hinged. One end of the upper umbrella rib 14 is hinged to the main transverse slide rail 6, and the other end is hinged to... The umbrella has two lower ribs 20 and one upper rib 14. A second upper rib 19 is hinged between two points where it is hinged to the lower rib 20 and the second-section umbrella support rib 17. A lower rib 15 is hinged to the end of the lower rib 20 closest to the second-section umbrella support rib 17, and the end of the lower rib 15 furthest from the lower rib 20 is hinged to the second-section umbrella support rib 17. The second-section umbrella support rib 17, the lower rib 15, the upper rib 14, and the lower rib 20 form a four-link structure. The upper rib 14 is parallel to the lower rib 15.

[0024] The end of the second-section upper rib 19 away from the first-section upper rib 14 is hinged to the third-section upper rib 21. The end of the second-section lower rib 20 away from the first-section lower rib 15 is hinged to the third-section lower rib 22 and the third-section upper rib 21. The hinge position of the third-section lower rib 22 and the second-section lower rib 20 is located between the first-section upper rib 14 and the third-section upper rib 21. The first-section upper rib 14, the second-section upper rib 19, the third-section upper rib 21 and the second-section lower rib 20 form a four-link structure. The second-section upper rib 19 and the second-section lower rib 20 are parallel.

[0025] The end of the three-section upper umbrella rib 21 away from the second-section upper umbrella rib 19 is hinged to the end of the terminal upper umbrella rib 23 and the terminal lower umbrella rib 24. The position where the terminal lower umbrella rib 24 is hinged to the three-section upper umbrella rib 21 is between the second-section upper umbrella rib 19 and the terminal upper umbrella rib 23. The end of the terminal lower umbrella rib 24 near the third-section lower umbrella rib 22 is hinged to the end of the third-section lower umbrella rib 22 away from the second-section lower umbrella rib 20. The vertical umbrella rib structure includes a short pole 30 hinged to the end of the terminal upper umbrella rib 23 away from the three-section upper umbrella rib 21. The end of the short pole 30 away from the terminal upper umbrella rib 23 is hinged to an inner umbrella rib 26 and a second short pole 31. The short pole 30 is hinged to the terminal lower umbrella rib 24. The position where the short pole 30 is hinged to the terminal lower umbrella rib 24 is between the terminal upper umbrella rib 23 and the second short pole 31. The three upper umbrella ribs 21, the lower umbrella rib 23, the short rod 30, and the lower umbrella rib 24 form a four-bar linkage structure, with the upper umbrella rib 23 and the lower umbrella rib 24 being parallel to each other.

[0026] One end of the lower umbrella rib 24 away from the main transverse slide rail 6 is hinged to an outer umbrella rib 25, and the outer umbrella rib 25 is hinged to two short rods 31; the end of the outer umbrella rib 25 away from the lower umbrella rib 24 is hinged to two inner umbrella ribs 28, and the position where the two short rods 31 are hinged to the outer umbrella rib 25 is located between the two inner umbrella ribs 28 and the lower umbrella rib 24; the lower umbrella rib 24, the short rod 30, the two short rods 31 and the outer umbrella rib 25 form a four-bar linkage structure in the shape of a convex quadrilateral.

[0027] One end of the inner umbrella rib 26 away from the short rod 30 is hinged to a three-section short rod 32 and a four-section short rod 33. The end of the three-section short rod 32 away from the inner umbrella rib 26 is hinged to an outer umbrella rib 25. The hinge position between the three-section short rod 32 and the inner umbrella rib 26 is located between the two-section short rod 31 and the two-section inner umbrella rib 28. The two-section short rod 31, the inner umbrella rib 26, the three-section short rod 32 and the outer umbrella rib 25 form a four-link structure. The inner umbrella rib 26 and the outer umbrella rib 25 are parallel.

[0028] The end of the four-section short rod 33 away from the first inner umbrella rib 26 is hinged to the second inner umbrella rib 28. The end of the second inner umbrella rib 28 away from the first outer umbrella rib 25 is hinged to the third vertical umbrella rib 29. The hinge position between the four-section short rod 33 and the second inner umbrella rib 28 is located between the first outer umbrella rib 25 and the third vertical umbrella rib 29. The three-section short rod 32, the four-section short rod 33, the first outer umbrella rib 25 and the second inner umbrella rib 28 form a four-link structure with a concave quadrilateral shape.

[0029] Two outer umbrella ribs 27 are hinged between one outer umbrella rib 25 and three vertical umbrella ribs 29. One end of the two outer umbrella ribs 27 is hinged to the top of the three vertical umbrella ribs 29, and the other end is hinged to one outer umbrella rib 25, with the hinge position located between the two short rods 31 and the two inner umbrella ribs 28. The three vertical umbrella ribs 29 are hinged to the end of the two inner umbrella ribs 28 away from the one outer umbrella rib 25. The one outer umbrella rib 25, the two outer umbrella ribs 27, the three vertical umbrella ribs 29 and the two inner umbrella ribs 28 form a four-bar linkage structure, with the two outer umbrella ribs 27 and the two inner umbrella ribs 28 being parallel.

[0030] like Figure 8-9 As shown, the lateral telescopic assembly also includes a secondary lateral slide rail 12 parallel to the main lateral slide rail 6. Each secondary lateral slide rail 12 is slidably connected to a pair of passive sliders 35. The passive sliders 35 are slidably arranged along the length direction of the secondary lateral slide rail 12. Each pair of passive sliders 35 is hinged to the end of a pair of shear bars 9. A secondary lateral slide rail 12 is arranged every four pairs of shear bars 9 from the main lateral slide rail 6 in the forward and backward direction. Each secondary lateral slide rail 12 is fixedly connected to a vertical rod 36 perpendicular to it in the middle. Each vertical rod 36 is connected to a pair of supporting guide rods 37 between it and the pair of shear bars 9 above it. The two ends of each supporting guide rod 37 are omnidirectionally connected to the vertical rod 36 and the shear bars 9, respectively. Each secondary lateral slide rail 12 is connected to a horizontal umbrella rib mechanism 13 at both ends. The passive transmission rod 18 and an outer umbrella rib 25 of the horizontal umbrella rib mechanism 13 connected to the secondary lateral slide rail 12 are hinged to the passive sliders 35 and the secondary lateral slide rail 12, respectively. The rotation axes of the umbrella ribs, umbrella support ribs, passive transmission rods 18, short rods, and vertical rods in the horizontal support umbrella rib structure are all perpendicular to the main horizontal slide rail 6 or the secondary horizontal slide rail 12 connected to this horizontal support umbrella rib structure. The canopy 4 is connected to the upper umbrella ribs, outer umbrella ribs, and vertical rods; steel wire can be used for the short rods.

[0031] When the parking plane is unfolded, the automatic telescopic rod 5 is activated. The automatic telescopic rod 5 extends and drives the inner telescopic rod 8 to rotate around the bottom end of the outer telescopic rod 3. At the same time, the bottom end of the inner telescopic rod 8 moves towards the top end of the outer telescopic rod 3. When the automatic telescopic rod 5 stops, the inner telescopic rod 8 and the outer telescopic rod 3 rotate 90° and the inner telescopic rod 8 moves to its upper limit position. When the outer telescopic rod 3 rotates, it drives the end of the cover transmission rod 11 connected to it to rotate, and the cover transmission rod 11 pushes open the cover 2.

[0032] As the inner telescopic rod 8 moves upward, it drives the main transverse slide rail 6 to move upward. The increased distance between the main transverse slide rail 6 and the outer telescopic rod 3 causes the slider transmission rod 10 to rotate around the outer telescopic rod 3, thereby driving the active slider 7 to move towards the middle of the main transverse slide rail 6. The ends of a pair of cross-scissor rods 9 connected to the active slider 7 move closer to each other, ultimately causing the cross-scissor telescopic frame to extend and unfold. Each pair of cross-scissor rods 9 moves closer to each other, and at the same time, the passive sliders 35 move closer to each other. The cross-scissor telescopic frame drives the secondary transverse slide rail 12 and the cross-bracing umbrella rib mechanism 13 to move together, causing the canopy 4 to extend in the front-to-back direction. After the cross-scissor telescopic frame extends forward and backward, under the action of gravity, the cross-scissor telescopic frame gradually droops from the middle to both ends, causing the canopy 4 to block the front and back directions of the vehicle.

[0033] As the paired active sliders 7 and passive sliders 35 approach each other, they drive the passive transmission rod 18 to move together with its connected end. The passive transmission rod 18 drives the first umbrella rib 16 and the second umbrella rib 17 to rotate. The second umbrella rib 17 drives the horizontal support umbrella rib mechanism 13 to unfold laterally. After each horizontal support umbrella rib is unfolded, it is bent at nearly 90 degrees, so that the canopy 4 can cover the left and right sides of the vehicle. After the canopy is unfolded, as... Figure 10 As shown. When the canopy is retracted, the automatic telescopic rod shortens and resets, causing the telescopic shading mechanism to return to its original position with the canopy, and the storage box closes.

[0034] Example 2 The rest of this embodiment is the same as that of embodiment 1, except that: Figure 11 As shown, the top of the outer telescopic rod 3 is connected to two pairs of sliding support rods 34. One end of each pair of sliding support rods 34 is rotatably connected to the outer telescopic rod, and the other end is slidably connected to the shearing rod 9 connected to the active slider 7.
