[0035] Please refer to Figures 1-11 The utility model provides technical scheme as follows:

[0036] The push-pull type vehicle-mounted platform includes inside flat bar 1, inside flat bar 1 is equipped with two and is fixedly connected with multiple base pipes 2 between the two, the rod body of inside flat bar 1 is evenly distributed with connecting window 3, and the connecting window 3 of one end of base pipe 2 is communicated with one of inside flat bar 1, and the other end is spaced apart from the connecting window 3 of the other inside flat bar 1, and the inside flat bar 1 is slidably connected with the inner pull rod 4 in the base pipe 2, and the inner pull rod 4 is communicated with the connecting window 3 of the base pipe 2 and is slidably connected with the connecting window 3, and the inner pull rod 4 end is fixedly connected with the side frame 5.

[0037] Two use embodiments

[0038] The vehicle-mounted platform is installed on the roof of the vehicle, can be used as the roof luggage rack, can also be unfolded and used as the roof extension tent, when being folded, the inner pull rod 4 is folded in the base pipe 2, so that the thickness of the vehicle-mounted platform is the same when being unfolded and folded, and the specific thickness is the thickness of the base pipe 2, when the base pipe 2 uses the ultra-thin pipe, the thickness of the vehicle-mounted platform is also ultra-thin, so that the height of the whole vehicle after installation is greatly reduced, the whole vehicle-mounted platform is light and thin, and meets the demand of various vehicle-mounted requirements.

[0039] When being unfolded, the side frame 5 can be pulled out, so that all the inner pull rods 4 are pulled out together, and the roof tent is formed and extended out of the vehicle, the unfolding mode is simple and convenient, sliding is smooth, labor-saving and easy to operate.

[0040] Most of the vehicle models choose two sets of expansion mode can meet more demand, more economical and practical.

[0041] Three sets of use examples

[0042] Also includes side pull rod 6, side pull rod 6 and inner pull rod 4 structure is same, side pull rod 6 is located at the interval of base pipe 2, side pull rod 6 passes through the connecting window 3 arranged at the interval of base pipe 2 and is slidably connected with the connecting window 3, and the end of side pull rod 6 is also fixedly connected with side frame 5.

[0043] On the basis of two sets of expansion, the side frame 5 is pulled out from the other side, thereby driving all the side pull rods 6 to extend out, forming a roof canopy on both sides of the vehicle body, with the largest expansion area, which can meet the needs of multiple people, and the side pull rods 6 are located at the interval of the base pipe 2 after folding, and the inner pull rod 4 is located in the base pipe 2, without changing the overall thickness, and has the largest expansion area; the overall vehicle platform has high strength and can load more and heavier objects.

[0044] Among them, the inner cavity pipe 201 is in the shape of 8, and the inner pull rod 4 is in the shape matched with the inner cavity pipe 201, so that the two are stable during sliding, and can be relatively close after folding, and are not easy to produce abnormal sound.

[0045] Among them, the auxiliary pulley 11 and the stop block 12 installed at the end of the inner pull rod 4 slide in the auxiliary sliding groove 203 of the base pipe 2 during the sliding process of the inner pull rod 4, and the auxiliary pulley 11 on the inner side of the inner cavity pipe 201 slides in the balance sliding way 10 on both sides of the inner pull rod 4, and the two are cross-slidably connected through the respective auxiliary pulleys 12, so that the whole sliding process is stable and smooth, which can enhance the stability and service life of the sliding system, and make it more durable and not easy to be damaged; when the inner pull rod 4 slides outward until the stop block 12 of the inner pull rod 4 slides to the auxiliary pulley 11 on the inner side of the inner cavity pipe 201, it cannot slide out under the double restriction of the auxiliary pulley 11 of the inner cavity pipe 201 and the connecting window 3, thereby limiting the limit position of the inner pull rod 4, avoiding complete disengagement, and multiple restrictions enable the inner pull rod 4 to maintain a relatively flush state when extended, and the end is not easy to fall off.

[0046] The structure of the side pull rod 6 is the same as that of the inner pull rod 4, and the auxiliary pulley 11 and the stop block 12 at the end of the side pull rod 6 slide in the side sliding pipe 202 when the side pull rod 6 is pulled out, and the auxiliary pulley 11 at the end of the side sliding pipe 202 slides in the balance sliding way 10 of the side pull rod 6, and also forms cross-slidably connected, and the whole sliding process is stable and smooth, which can enhance the stability and service life of the sliding system.

[0047] The two ends of the inner flat bar 1 are fixedly connected with end pipes 14, and the two ends of the end pipe 14 are fixedly connected with elbow joints 15. The end pipe 14, the elbow joint 15 and the side frame 5 can be enclosed into a round rectangular shape after the overall vehicle-mounted platform is folded, which is more beautiful. Meanwhile, the inner flat bar 1 is fixedly connected with a connecting pull piece 16 on one side parallel to the inner flat bar 1. The two ends of the side frame 5 are provided with fixed holes 17, and the fixed holes 17 are opposite to the holes of the connecting pull piece 16. When the side frame 5 is folded on the side of the inner flat bar 1, the side frame 5 is sleeved on the connecting pull piece 16. At this time, the side frame 5 can be fixed and kept in the folded state by inserting a pin into the fixed hole 17 and the hole of the connecting pull piece 16, thereby achieving the function of fixed connection.

[0048] The side frame 5 is connected with fixed blocks 18 on the outer side, and the fixed blocks 18 are used to connect ladders 19 and support rods 20. Two adjacent fixed blocks 18 are fixedly connected with a lower hanging rod 21 in the middle, and the lower hanging rod 21 is used to connect the ladders 19.

[0049] When the two-ladder or three-ladder is unfolded, the ladders 19 and the support rods 20 can be connected with the fixed blocks 18 on the outer side of the side frame 5 to support the inner pull rod 4 and the side pull rod 6 extended out, thereby forming a stable extended roof. The ladders 19 can also be used by workers to climb to the roof to facilitate the taking or arrangement of the roof. When the ladders 19 are folded upward and stored on the top of the vehicle-mounted platform, the trunk position is not enough, which is very convenient. When the ladders 19 are folded down and pulled, the side frame 5 can be used, which is also more flexible and multi-purpose.

[0050] The side frame 5 is provided with support slides 22 on the outer side, and the support slides 22 are C-shaped. The fixed blocks 18 are located in the support slides 22 and are in sliding cooperation with the support slides 22. The ladders 19 and the support rods 20 are of a telescopic type.

[0051] If the fixed blocks 18 are slidable, the ladders 19 and the support rods 20 can be slid to a suitable position for support according to the actual terrain, or the ladders 19 and the support rods 20 can be arranged on the side to facilitate front access, and then fixed by pins or fastening bolts.
