DETAILED DESCRIPTION

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] like Figure 1-11 As shown, an expandable folding tent for converting an SUV into a motorhome comprises a vehicle 1, a folding frame 2, a lifting pedal 7 and a waterproof cloth 8, wherein the folding frame 2 is installed in the trunk of the vehicle 1, one end of the folding frame 2 extends into the trunk of the vehicle 1, one end of the folding frame 2 is fixed to the inner wall of the trunk of the vehicle 1, the folding frame 2 is covered with a waterproof cloth 8, and a lifting pedal 7 is arranged at the bottom of the folding frame 2. When the folding frame 2 is not unfolded, the folding frame 2 is folded and laid flat in the trunk; The folding skeleton 2 includes a rotating shaft 3, a supporting frame 4, an expansion frame 5 and a folding connecting rod 6, wherein the left and right ends of the rotating shaft 3 are installed at the bottom of the trunk through a bearing seat and a bearing, and the rotating shaft 3 is rotatably connected to the bottom of the trunk, so that the rotating shaft 3 rotates, and the supporting frames 4 are multiple and connected by the folding connecting rod 6, so that the multiple supporting frames 4 are folded and unfolded through the folding connecting rod 6, and each supporting frame 4 is a gantry, so that the multiple gantry frames are arranged side by side, and after the supporting frames 4 are unfolded, the bottom of the supporting frames 4 is pressed on the rear At the bottom of the trunk, a support frame 4 at one end is connected to the rotating shaft 3, that is, the bottom of the first support frame 4 at the front end is fixed to the rotating shaft 3 by bolts. When the support frame 4 is folded, the support frame 4 is rotated to make the support frame 4 flat in the trunk. When multiple support frames 4 are unfolded, the length of the multiple support frames 4 is consistent with the length from the rotating shaft 3 to the inner edge of the trunk; an extension frame 5 is installed on the support frame 4 at the rear end through a folding connecting rod 6. The extension frame 5 extends out of the trunk when unfolded. A plurality of expansion frames 5 are arranged side by side, and the expansion frames 5 are straight rods. Swing rods 9 are hinged at the left and right ends of each expansion frame 5. An elastic folding assembly 10 is arranged between the swing rod 9 and the expansion frame 5. When unfolding, the swing rod 9 swings outward, thereby increasing the width of the tent. A telescopic rod 30 is hingedly installed at the bottom of the swing rod 9. Due to gravity, the telescopic rod 30 is always vertically downward. A lifting pedal 7 is installed at the bottom of the telescopic rod 30. The lifting pedal 7 is a plurality of pieces, and the plurality of lifting pedals 7 are hinged to each other. When unfolding, the support frame 4 is rotated into a vertical state, and then the expansion frame 5 at the rear end is pulled outward, and the expansion frame 5 and the support frame 4 are pulled backward and unfolded by the traction of the folding connecting rod 6, so that the swing rod 9 expands outward under the action of the elastic folding component 10. Since the expansion frame 5 is located outside the trunk after unfolding, the outward expansion of the swing rod 9 is not restricted by the width of the vehicle 1. Then the telescopic rod 30 extends downward under the action of the lifting pedal 7, so that the lifting pedal 7 is in contact with the ground, and a flat plate is laid on the lifting pedal 7 for waterproofing.

[0028] The folding link 6 is an X-cross rod, and the folding link 6 is two rods hinged to each other from the middle section. The four ends of the folding link 6 are respectively slidably connected to the support frame 4 and the expansion frame 5 (that is, there are multiple folding links 6, and a folding link 6 is arranged between every two support frames 4, between every two expansion frames 5, and between the expansion frame 5 and the support frame 4). A slider 18 is installed at the end of the folding link 6 in a hinged manner, and a slide groove 19 for the slider 18 to slide is opened on the front of the support frame 4 and the expansion frame 5 (that is, on the front and rear sides of the support frame 4 and the expansion frame 5), and the slider 18 slides on the support frame 4 and the expansion frame 5; a locking assembly 20 and an unlocking assembly 22 are arranged on the support frame 4 and the expansion frame 5. When the support frame 4 and the expansion frame 5 are fully unfolded, the locking assembly 20 will fold the link 6. When it needs to be folded, the locking assembly 20 is unlocked by the unlocking assembly 22 and then folded.

[0029] The support frame 4 and the expansion frame 5 are both provided with elastic top pins 21 in the slide grooves 19. The elastic top pins 21 are located on the front side of the support frame 4 or the expansion frame 5. One end of the elastic top pin 21 extends into the support frame 4 or the expansion frame 5. The elastic top pin 21 is elastically connected to the support frame 4 or the expansion frame 5. The elastic top pin 21 is inclined on the outward side. A through hole is opened on the support frame 4 or the expansion frame 5 and the through hole is located in the slide groove 19. The elastic top pin 21 is inserted into the through hole. A spring is embedded between the elastic top pin 21 and the bottom of the through hole. The elastic top pin 21 is pushed outward by the spring. Two elastic top pins 21 are provided in each slide groove 19 of each support frame 4 or the expansion frame 5. The two elastic top pins 21 are symmetrically arranged on the left and right, wherein each elastic top pin 21 is The outer side surface of the elastic ejector pin 21 is an inclined surface inclined inwardly. When the sliders 18 on the support frame 4 and the expansion frame 5 are close to each other, the slider 18 presses the inclined surface of the elastic ejector pin 21 to press the elastic ejector pin 21 into the through hole, so that the slider 18 passes over the elastic ejector pin 21, so that the slider 18 is located on the inner side of the elastic ejector pin 21, and a limiting protrusion is fixed in the slide groove 19 by welding, and the slider 18 is clamped and locked by the limiting protrusion and the elastic ejector pin 21; when the slider 18 slides, it presses the inclined surface to press the elastic ejector pin 21 into the support frame 4 and the expansion frame 5; the unlocking component 22 is a trigger rod 24, and a trigger rod 24 (that is, a trigger rod in the support frame 4) is inserted on the side of the support frame 4 and the expansion frame 5 away from the elastic ejector pin 21. The rear side surfaces of the support frame 4 and the expansion frame 5 are also provided with through holes, and the through holes are located above the slide slots 19. A trigger rod 24 is inserted into the through holes on the rear side surfaces of the support frame 4 and the expansion frame 5, and one end of the trigger rod 24 extends out of the support frame 4 and the expansion frame 5). A lifting rod 23 is arranged between the end of the trigger rod 24 and the elastic top pin 21. A through hole extending downward is provided at the top of the support frame 4 and the expansion frame 5, and a lifting rod 23 is inserted into the through hole at the top of the support frame 4 and the expansion frame 5. The bottom of the lifting rod 23 is an inclined surface, and a through hole for the lifting rod 23 to pass through is provided when the elastic top pin 21 extends into the top surface of the support frame 4 or the expansion frame 5. The lifting rod 23 is lifted and lowered in the through hole, and the top of the lifting rod 23 is an inclined surface and the lifting rod 23 is pushed up and down. The inclined surface of the upper part contacts the trigger rod 24, so that when the rearmost expansion frame 5 is folded, the trigger rod 24 is pressed, and the trigger rod 24 presses the lifting rod 23 downward, so that the lifting rod 23 descends. When the lifting rod 23 descends, the inclined surface presses the through hole at the top of the elastic top pin 21, and when the lifting rod 23 descends, the elastic top pin 21 retreats and extends into the through hole on the front side of the support frame 4 and the expansion frame 5, so that the slider 18 can move outward, so that folding can be performed. After the first expansion frame 5 is folded and the two expansion frames 5 are folded, another expansion frame 5 presses the trigger rod 24 on the other expansion frame 5, so that the next set of folding connecting rods 6 are unlocked, and the support frame 4 is unlocked away in accordance with the principle of unlocking the expansion frame 5.

[0030] The elastic folding assembly 10 includes a sliding sleeve 11, a support rod 12 and an elastic assembly 13. The expansion frame 5 is sleeved with a sliding sleeve 11 that slides left and right on the expansion frame 5. The support rod 12 is hinged between the sliding sleeve 11 and the swing rod 9. When the sliding sleeve 11 moves outward, the swing rod 9 swings outward and expands. Each expansion frame 5 is sleeved with two sliding sleeves 11 and each sliding sleeve 11 is located at the left and right ends of the expansion frame 5. Multiple sliding sleeves 11 at the same end of multiple expansion frames 5 are connected to each other and move synchronously. The distance between two adjacent sliding sleeves 11 is 1 / 4 of the expansion frame 5. The expansion frame 5 is connected by a double-link mechanism 14, which will not affect the folding of the expansion frame 5. An elastic component 13 is arranged between the sliding sleeve 11 and the expansion frame 5. The elastic component 13 is a spring. A spring is fixed between the sliding sleeve 11 and the expansion frame 5. The sliding sleeve 11 is pushed to the left and right ends of the expansion frame 5 by the spring. Locking pins 15 and pin holes 16 are arranged on the sliding sleeve 11 and the expansion frame 5. When the swing arm 9 is fully unfolded, the locking pin 15 on the sliding sleeve 11 is inserted into the pin hole 16 on the expansion frame 5 for locking.

[0031] The locking pin 15 is an elastic telescopic pin (the locking pin 15 is an inner and outer pin nested with each other, a deep hole for the inner pin to extend into is opened on the outer pin, the inner pin is inserted into the outer pin deep hole, and a spring for pushing the inner pin outward is embedded between the inner pin and the outer pin), a through hole is opened on the wall of the sliding sleeve 11, the locking pin 15 is inserted into the through hole of the sliding sleeve 11, the locking pin 15 passes through the sliding sleeve 11, a spring is fixed between the locking pin 15 and the sliding sleeve 11 by welding, a pin hole 16 is opened on the expansion frame 5, when the locking pin 15 is pressed, the locking pin 15 extends into the pin hole 16, a pressing block 17 is fixed on the double-link mechanism 14 by welding, when the expansion frame 5 is unfolded, the pressing block 17 of the double-link mechanism 14 presses on the tail of the locking pin 15; when working, the sliding sleeve 11 moves outward under the action of the elastic group, The swing arm 9 is opened outward by the strut 12. When the sliding sleeve 11 moves to the locking pin 15 and is opposite to the pin hole 16, the locking pin 15 extends into the pin hole 16 for locking. In this way, the sliding sleeve 11 is locked. Since a double-link mechanism 14 is used between the sliding sleeves 11, when the expansion frame 5 is not unfolded, the double-link mechanism 14 is folded, and the pressing block 17 is separated from the locking pin 15. When the expansion frame 5 is fully unfolded, the double-link mechanism 14 is unfolded, and the pressing block 17 presses the locking pin 15 inward. When the locking pin 15 is not opposite to the pin hole 16, the inner pin of the locking pin 15 is compressed. When the sliding sleeve 11 slides to be opposite to the pin hole 16, the inner pin is lifted and extends into the pin hole 16 to complete the locking. In this way, when all the expansion frames 5 are fully folded, the swing arm 9 can be pressed inwardly and folded, thereby realizing the locking of the swing arm 9.

[0032] The telescopic rod 30 is hinged on the end of the swing rod 9 located on the outside, and the universal head 25 is installed at the bottom of the telescopic rod 30 by bolt fastening. The universal head 25 is installed on the two end sides of the lifting pedal 7 by bolt fastening. The lifting plate is hinged by multiple bottom plates 26, and each bottom plate 26 is a telescopic plate. When the swing rod 9 is fully unfolded, the bottom of the telescopic rod 30 extends and contacts the ground, and the bottom plate 26 contacts the ground. When folding is required, when the frame 5 is expanded, the bottom plate 26 is folded, and when the swing rod 9 swings inward and folds, the bottom plate 26 retracts, and the telescopic rod 30 also retracts to complete the folding.

[0033] The bottom of each base plate 26 is covered with an anti-skid pad 27 by glue.

[0034] The outer wall of the waterproof cloth 8 of the outer wall of the support frame 4 is covered with a C-shaped inflatable strip 28 by sewing. When the support frame 4 is unfolded, the inflatable strip 28 is inflated and filled between the inner wall of the trunk and the waterproof cloth 8 to seal.

[0035] Limit rods 29 facing the expansion frame 5 are fixed by welding on both sides of the support frame 4 close to the expansion frame 5. When folding, the swing rod 9 is pressed against the limit rods 29 for limiting, preventing the swing rod 9 from swinging outward and unfolding.
