[0032] It should be noted that the two ends of the threaded rod 32 are rotatably connected to the inner side of the translation groove 31 through bearings, and a plurality of concave slide rails 33 are symmetrically distributed on both sides of the threaded rod 32; after the opening and closing plate 2 is opened from the rear of the chassis body 1, the threaded rod 32 can be driven to rotate through the cooperation of the power source, which can drive the moving block 34 threadedly connected to the side of the threaded rod 32 to move along the length direction of the threaded rod 32, and drive the support plate 3 on the top of the moving block 34 to move synchronously. At the same time, a plurality of convex sliding blocks 35 at the bottom of the support plate 3 will slide and limit on the top of the plurality of concave slide rails 33, so that the support plate 3 can be translated to the outer side of the rear of the chassis body 1, and with the cooperation of the supporting sliding assembly, the bottom of the support plate 3 located on the outer side of the chassis body 1 can be supported, and the extended support plate 3 can provide users with a spacious outdoor rest platform, which can be used for outdoor activities such as picnics and leisure reading, greatly improving the use value and entertainment of the RV, thereby meeting the diverse use needs of users.

[0033] In this embodiment, the power source includes: a servo motor 4 fixed to the inner side of the chassis body 1, a driving gear 41 fixed to the output end of the servo motor 4, and a driven gear 42 fixed to the side of the threaded rod 32; the side of the driving gear 41 is meshed with the side of the driven gear 42.

[0034] It should be noted that starting the servo motor 4 drives the driving gear 41 at the output end to rotate. Since the side of the driving gear 41 is meshed with the side of the driven gear 42, when the driving gear 41 rotates, it can drive the driven gear 42 and the threaded rod 32 to rotate, thereby providing rotational power for the threaded rod 32.

[0035] In this embodiment, a limit block 5 is fixed at one end of the concave slide rail 33 for limiting the convex slider 35 when it slides; through the setting of the limit block 5, when the support plate 3 drives the convex slider 35 at the bottom to slide on the top of the concave slide rail 33, when the convex slider 35 slides to one end of the concave slide rail 33, it can play a role in sliding limitation of the convex slider 35.

[0036] like Figure 3 As shown, in this embodiment, the supporting sliding assembly includes: a storage groove 6 opened on one side of the supporting plate 3, a supporting rod 61 hinged on the inner side of the storage groove 6, and a rotating wheel 62 rotatably connected to one end of the supporting rod 61; a positioning block 63 is fixed to the bottom of the supporting plate 3, a connecting bolt 64 is threadedly connected to the positioning block 63, a connecting hole 65 is opened on one side of the supporting rod 61, and one end of the connecting bolt 64 is threadedly connected to the inner side of the connecting hole 65.

[0037] It should be noted that the width of the support rod 61 is the same as the width of the storage groove 6; when the support plate 3 gradually translates toward the outer side of the rear end of the chassis body 1, when part of the bottom of the support plate 3 translates out of the inner side of the chassis body 1, the movement of the support plate 3 is stopped, and the support rod 61 is flipped out of the storage groove 6 and perpendicular to the plane, so that the bottom wheel 62 contacts the ground, and at the same time, the connecting bolt 64 is rotated so that one end is threadedly connected to the connecting hole 65 on one side of the support rod 61, so that the posture of the support rod 61 can be fixed, and then the bottom of the support plate 3 that translates out of the inner side of the chassis body 1 can continue to be slidably supported, thereby improving the stability and reliability of the support plate 3 during the extension process.

[0038] In this embodiment, the bottom of the opening and closing plate 2 is hinged to the bottom of the chassis body 1 , and the side is snap-fitted to the side of the chassis body 1 through a lock; a groove 7 is provided on one side of the opening and closing plate 2 .

[0039] It should be noted that, by manually pulling the pull groove 7, the bottom of the opening and closing plate 2 can be driven to close at the rear of the chassis body 1 through the lock snap connection with the hinge point at the bottom of the chassis body 1, or the opening and closing plate 2 can be opened at the rear of the chassis body 1.

[0040] In this embodiment, a moving component is provided at the bottom of the chassis body 1, and the moving component includes: a plurality of fixed blocks 8 fixed at the bottom of the chassis body 1, a transmission rod 81 rotatably connected to the plurality of fixed blocks 8, and wheels 82 fixed at both ends of the transmission rod 81; a mudguard 83 is provided on the top of the wheel 82, and one side of the mudguard 83 is fixed to one side of the chassis body 1.

[0041] It should be noted that when the chassis body 1 is driven to move for towing, the wheel 82 will drive the transmission rod 81 to rotate synchronously. The several fixed blocks 8 at the bottom of the chassis body 1 can provide the effects of rotation and support limitation during movement. Through the setting of the mudguard 83, the mud and other debris brought up by the wheel 82 during towing can be blocked.

[0042] like Figure 4 As shown, in this embodiment, a tripod 9 is fixed at the front of the chassis body 1, and a towing support is provided on one side of the tripod 9. The towing support includes: a fixed frame 91 fixed to one side of the tripod 9, a hydraulic rod 92 fixed to the inner side of the fixed frame 91, and a support plate 93 fixed to the hydraulic rod 92 at the bottom output end of the fixed frame 91; a towing pull ring 94 is fixed to the top of the fixed frame 91.

[0043] It should be noted that when the whole vehicle needs to be parked instead of towed, the hydraulic rod 92 is started to extend, and the output end located at the bottom of the fixed frame 91 will drive the support plate 93 to move downward. When the support plate 93 contacts the plane, it can support one side of the tripod 9, thereby improving the stability of the whole vehicle when parked, and through the setting of the towing pull ring 94, a connecting towing point can be provided when the whole vehicle is towed.

[0044] The utility model provides a complete vehicle, comprising any one of the above-mentioned pure electric trailer caravan chassis.

[0045] When used specifically, when the chassis body 1 is driven to be towed and moved, the wheel 82 will drive the transmission rod 81 to rotate synchronously. The fixed blocks 8 at the bottom of the chassis body 1 can provide the effect of rotation and support limit during movement. By setting the fender 83, the mud and other debris brought up by the wheel 82 during towing and moving can be blocked. After moving to the parking point, the hydraulic rod 92 is started to extend, and the output end at the bottom of the fixed frame 91 will drive the support plate 93 to move downward. When the support plate 93 contacts After reaching the plane, it can play a supporting role for one side of the tripod 9, thereby improving the stability of the whole vehicle when parked. Manually pull the pull groove 7, the bottom of the opening and closing plate 2 can be driven to open at the rear of the chassis body 1 with the hinge point at the bottom of the chassis body 1 as the center of the circle, and the servo motor 4 is started to drive the driving gear 41 at the output end to rotate. Since the side of the driving gear 41 is meshed with the side of the driven gear 42, when the driving gear 41 rotates, it can drive the driven gear 42 and the threaded rod 32 to rotate. The rotation can drive the moving block 34 threadedly connected to the side of the threaded rod 32 to move along the length direction of the threaded rod 32, and drive the support plate 3 on the top of the moving block 34 to move synchronously. At the same time, the several convex sliding blocks 35 at the bottom of the support plate 3 will slide and limit on the top of the several concave sliding rails 33, so that the support plate 3 can be translated to the outer side of the rear of the chassis body 1. When part of the bottom of the support plate 3 is translated out of the inner side of the chassis body 1, the movement of the support plate 3 is stopped, and the support rod 61 is flipped out of the storage groove 6 and perpendicular to the plane, so that the bottom wheel 62 contacts the ground. At the same time, the connecting bolt 64 is rotated so that one end is threadedly connected to the connecting hole 65 on one side of the support rod 61, so that the posture of the support rod 61 can be fixed, and then the support plate 3 can continue to be translated out of the bottom of the inner side of the chassis body 1 for sliding support. The extended support plate 3 can provide users with a spacious outdoor rest platform for outdoor activities such as picnics and leisure reading, which greatly improves the use value and entertainment of the RV, thereby meeting the diverse use needs of users.
