[0002] Benefiting from consumers' pursuit of personalized travel experiences, towed recreational vehicles have become increasingly popular in recent years. The towing mechanism of towed recreational vehicles plays a crucial role in ensuring travel safety. The towing mechanism mainly includes a tow hook installed on the front vehicle and a towing seat installed on the recreational vehicle. When towing a recreational vehicle, the tow hook of the front vehicle needs to be connected to the towing seat.

[0003] For different towing vehicles, the heights of their tow hooks are mostly inconsistent. Therefore, the towing seat of the recreational vehicle needs to be rotatably adjusted in the vertical direction. The rotational adjustment of the towing seat is mostly achieved by manually shaking a rocker, which is time-consuming and laborious during adjustment, and the adjustment speed is relatively slow. At the same time, when hooking up, when the tow hook and the towing seat are not in the same horizontal plane, it is necessary to reverse the vehicle multiple times to adjust the position of the tow hook or forcefully drag the towing seat to find the tow hook, resulting in a low hooking efficiency of the towing seat.

Figure 2

[0026] Figures 1-7 Please refer to , the present application provides the following technical solutions: A traction seat adaptive adjustment mechanism for a small trailer, including a mounting plate 8; a reduction motor 6 is arranged on the mounting plate 8, the output shaft of the reduction motor 6 is connected to a main shaft 7 through a coupling, a main shaft brake mechanism 9 for locking the main shaft 7 is arranged on the mounting plate 8, the outer side surface of the main shaft 7 is rotatably connected with a rotating arm 10, one end of the outer side surface of the rotating arm 10 far away from the mounting plate 8 is provided with a first support 3 that can rotate horizontally, a dragging plate 14 that can rotate vertically is installed on the first support 3, and a hanging hole 1 is arranged on the dragging plate 14.

[0027] Specifically, when mounting the towing board 14, first control the front vehicle to reverse so that the hook of the front vehicle is as close as possible to the towing board 14. Then, hold the handle 2 and lift the towing board 14. Control the rotation of the deceleration motor 6 to drive the rotating arm 10 to make pitching adjustment. At the same time, swing the position of the towing board 14 in the horizontal plane so that the hanging hole 1 can be successfully mounted on the hook of the front vehicle.

[0028] Further, a plurality of mounting holes are provided at the outer side edge of the mounting plate 8.

[0029] Specifically, the arrangement of the mounting holes facilitates the quick connection of the hook.

[0030] Further, the main shaft 7 is rotationally connected to the mounting plate 8 through a bearing support.

[0031] Specifically, the main shaft 7 is rotationally connected to the bearing support through a bearing, and the bearing support is fixed on the mounting plate 8.

[0032] Further, the main shaft brake mechanism 9 includes a housing 94 fixed on the mounting plate 8. A positioning gear 93 is installed on the outer side of the main shaft 7. The positioning gear 93 is arranged inside the housing 94. A hydraulic telescopic rod 91 is provided inside the housing 94. An insertion plate 92 is installed at the telescopic end of the hydraulic telescopic rod 91. The insertion plate 92 is arranged in a clamping correspondence with the tooth grooves of the positioning gear 93.

[0033] Specifically, after the towing board 14 is mounted, the hydraulic telescopic rod 91 extends to insert the insertion plate 92 into the tooth grooves of the positioning gear 93, thereby effectively preventing the rotation of the main shaft 7 and realizing the position fixation of the rotating arm 10.

[0034] Further, a positioning rod 95 is provided inside the housing 94. The positioning rod 95 is slidably connected to the insertion plate 92.

[0035] Specifically, the insertion plate 92 slides along the positioning rod 95, which can effectively improve the torsional resistance of the insertion plate 92.

[0036] Further, a positioning shaft one 4 is rotatably connected to the end of the rotating arm 10. A support one 3 is installed on the positioning shaft one 4. A positioning plate 11 is provided on the support one 3. A support two 13 is provided on the outer side of the positioning plate 11. A positioning shaft two 12 is fixedly connected to the support two 13. The positioning shaft two 12 is rotatably connected to the towing board 14.

[0037] Specifically, the rotating arm 10 is rotationally connected to the positioning shaft one 4 through a bearing, and the positioning shaft two 12 is rotationally connected to the towing board 14 through a bearing.

[0038] More specifically, the positioning shaft two 12 is composed of an inner threaded rod 121 and a positioning stud 122. The positioning stud 122 is threadedly connected to the inner threaded rod 121, and the inner threaded rod 121 is fixedly connected to the support two 13. After the dragging plate 14 is installed, the positioning stud 122 is locked. The end of the positioning stud 122 presses tightly against the outer surface of the support two 13, which can effectively prevent relative rotation between the dragging plate 14 and the support two 13.

[0039] Further, a handle 2 is installed on the outer side surface of the dragging plate 14.

[0040] Specifically, the setting of the handle 2 facilitates the rotation operation of the dragging plate 14.

[0041] Further, a triangular bracket 5 is provided on the outer side surface of the mounting plate 8, and a strip-shaped through groove 18 is provided on the upper surface of the rotating arm 10. The triangular bracket 5 is arranged through the strip-shaped through groove 18, and sliding mechanisms are provided at both the left and right ends of the outer side surface of the rotating arm 10; the sliding mechanism includes two sliders 16, both of the two sliders 16 are slidably connected to the rotating arm 10, the two sliders 16 are connected by a connecting rod 17, and a headed stud 15 is threadedly connected to the slider 16. The lower end surface of the headed stud 15 passes through a threaded hole provided on the slider 16 and presses tightly against the upper surface of the rotating arm 10.

[0042] Specifically, after the trailer to be towed is mounted, the two sliders 16 provided on the upper surface of the right end of the rotating arm 10 are slidably adjusted along the rotating arm 10, so that the connecting rod 17 provided between the two sliders 16 closely adheres to the outer side surface of the triangular bracket 5, and the headed stud 15 provided on the slider 16 is locked. When the locking mechanism of the main shaft 7 fails, the connecting rod 17 can abut against the outer side surface of the triangular bracket 5, which can effectively prevent the trailer from hitting the vehicle in front.

[0043] More specifically, after the trailer to be towed is mounted, the rotating arm 10 is horizontally pushed to adjust the support one 3 and the rotating arm 10 to the same vertical plane. Subsequently, the other two sliders 16 provided on the upper surface of the left end of the rotating arm 10 are slidably adjusted along the rotating arm 10, so that the connecting rod 17 provided between the two sliders 16 closely adheres to the outer surface of the support one 3. By locking the headed stud 15 provided on the slider 16, the rotation of the support one 3 during vehicle braking can be effectively prevented.

[0044] In use: Control the vehicle in front to reverse so that the hook of the vehicle in front approaches the towing plate 14. Adjust the height of the towing plate 14 according to the height of the hook of the vehicle in front so that the hanging hole 1 can be accurately connected to the hook of the vehicle in front. During specific operation, the output shaft of the reduction motor 6 drives the main shaft 7 to rotate, and the main shaft 7 drives the rotating arm 10 to make pitching adjustment. After the towing plate 14 arranged at the end of the rotating arm 10 is adjusted to an appropriate height, hold the handle 2 and lift the towing plate 14, and at the same time horizontally rotate the position of the towing plate 14 so that the hanging hole 1 can be quickly connected to the hook.

[0045] It should be noted that the input ends of the reduction motor 6 and the hydraulic pump are both electrically connected to the output end of the vehicle-mounted power supply through an external controller, and the hydraulic pump controls the telescopic movement of the hydraulic telescopic rod 91.
