[0027] See also Figure 6 The three-dimensional view of the rear pole and the lifting bracket separated is shown, and the fixing mechanism includes a crossbeam 1 arranged transversely along the rear of the vehicle, a traction column 11 and two support arms 12 extending transversely from the crossbeam; wherein the extended end of the traction column 11 can be inserted into a traction tube 14 located at the bottom of the rear pole 13 of the vehicle and connected thereto by a latch; the support arms are located on the left and right sides of the traction column, and the extended ends of the support arms are fixedly connected to the rear pole. The utility model can be easily inserted into the traction tube at the rear of various types of off-road vehicles / RVs, can be quickly installed, and has excellent versatility.

[0028] In a preferred embodiment, the lifting swing arm includes an upper swing arm and a lower swing arm that are hinged up and down, wherein one end of the lower swing arm is connected to the crossbeam 1, and the other end thereof is connected to the upper swing arm; one end of the upper swing arm is connected to the lower swing arm, and the other end thereof is connected to the support plate. The upper swing arm and the lower swing arm are essentially two parallelogram linkage mechanisms, so the support plate 10 can always be kept horizontal during the swing of the entire lifting swing arm.

[0029] Since motorcycles or bicycles are long objects, the lifting arm also needs to be made into a flat and long shape to support the motorcycle or bicycle and increase the stability of the system. Therefore, parallelogram linkage mechanisms are symmetrically arranged on the left and right sides of the lifting arm.

[0030] See also Figure 4 A perspective view of the tray being lowered is shown, and Figure 5The three-dimensional view of the lifting pallet is shown, and the lower swing arm includes two lower arm inner connecting rods 2, two lower arm outer connecting rods 3, a lower transverse connecting rod 4, two transfer arms 5 and two fixed arms 15; wherein the two fixed arms 15 are respectively fixed at the two ends of the crossbeam 1, and the transfer arm 5 has an upright vertical arm 5a and a horizontal flat arm 5b connected as one, and the upper swing arm is hinged on the flat arm 5b; one lower arm inner connecting rod 2 and one outer connecting rod 3 are arranged in parallel and hinged between the fixed arm 15 located on the left and the vertical arm 5a of a transfer arm 5, forming a lower arm left member of a parallelogram connecting rod structure; another lower arm inner connecting rod 2 and another outer connecting rod 3 are arranged in parallel and hinged between the fixed arm 15 located on the right and the vertical arm 5a of a transfer arm 5, forming a lower arm right member of a parallelogram connecting rod structure; the lower transverse connecting rod 4 is fixedly connected between the two lower arm inner connecting rods 2, and is located at the end position of the lower arm inner connecting rod 2 close to the transfer arm 5.

[0031] It should be noted that in order to reduce the weight of the lifting swing arm, the fixed arm 15 and the transfer arm 5 are not solid, but are formed by bending steel sheets, and their cross sections are in the shape of a "concave" character, as shown in FIG. Figure 4 and Figure 5 The lower arm inner connecting rod 2, the lower arm outer connecting rod 3, the upper arm inner connecting rod 6 and the upper arm outer connecting rod 7 are all hinged in the groove. This can reduce the weight of the lifting swing arm and increase the structural strength.

[0032] See also Figure 4 A perspective view of the tray being lowered is shown, and Figure 5 The three-dimensional view of the lifting plate is shown, and the upper swing arm includes two upper arm inner connecting rods 6, two upper arm outer connecting rods 7 and an upper horizontal connecting rod 24, wherein one upper arm inner connecting rod 6 and one upper arm outer connecting rod 7 are arranged in parallel and hinged between the left end of the plate 10 and the flat arm 5b of a transfer arm 5, forming an upper arm left member of a parallelogram connecting rod structure; another upper arm inner connecting rod 6 and another upper arm outer connecting rod 7 are arranged in parallel and hinged between the right end of the plate 10 and another transfer arm 5, forming an upper arm right member of a parallelogram connecting rod structure; the upper horizontal connecting rod 24 is fixedly connected between the two upper arm inner connecting rods 6; a linkage rocker is respectively provided between the lower arm left member and the upper arm left member, and between the lower arm right member and the upper arm right member, and the linkage rocker comprises a fixing plate 8 and a linkage rod 9, the fixing plate 8 is fixed on the lower arm outer connecting rod 3 and extends toward the rear of the vehicle, and the linkage rod 9 is hinged between the end of the fixing plate 8 and the upper arm inner connecting rod 6.

[0033] Because the drive device is installed in the lower swing arm, it is necessary to install a linkage rocker between the upper and lower swing arms. Figure 1 and Figure 2When the lower arm is raised to the right, the linkage rocker will pull up the upper arm and raise it to the right together. When the lower arm is lowered to the left, the linkage rocker will push the upper arm to the left and lower it together.

[0034] Combined with reference Figure 2 , Figure 5 and Figure 6 The driving device includes a hydraulic pump 20 and two hydraulic telescopic rods 21 which are hydraulically connected to each other. The hydraulic pump 20 is installed on the cross beam 1. A connecting ear 16 is fixed at each end of the lower cross connecting rod 4. One end of the hydraulic telescopic rod 21 is hinged to the bottom end of the fixed arm 15, and the other end is hinged to the connecting ear 16.

[0035] When the hydraulic telescopic rod 21 is retracted, since one end of the hydraulic telescopic rod 21 is hinged to the bottom end of the fixed arm 15 and the other end is hinged to the connecting ear 16, the hydraulic telescopic rod 21 will pull the top end of the lower arm inner connecting rod (2) toward the bottom end of the fixed arm 15 through the connecting ear 16 and the lower horizontal connecting rod 4, thereby causing the lifting swing arm to swing down. When the hydraulic telescopic rod 21 is extended, the hydraulic telescopic rod 21 will push the top end of the lower arm inner connecting rod (2) away from the bottom end of the fixed arm 15 through the connecting ear 16 and the lower horizontal connecting rod 4, thereby causing the lifting swing arm to swing upright.

[0036] In order to clamp the motorcycle wheel, in a preferred embodiment, a wheel bracket 17 is provided above the support plate 10. In other embodiments, a motorcycle stabilizer 18 is further provided in the middle of the support plate 10, and the motorcycle stabilizer can support the bottom between the two wheels of the motorcycle.

[0037] See also Figure 1 , Figure 2 and Figure 4 The cross beam 1 extends obliquely upward to limit the limit rod 19 of the lower swing arm from swinging toward the rear of the vehicle. This prevents the lifting swing arm from swinging excessively to the right and squeezing the parts and the rear of the vehicle.

[0038] The utility model also designs a motorhome with a universal lifting bracket. The motorhome comprises a lifting bracket, and the lifting bracket adopts the universal lifting bracket mentioned above.

[0039] The above embodiments are for illustration only and are not intended to be limiting. Any equivalent modifications or changes made thereto without departing from the spirit and scope of the present application shall be included in the scope of the claims of the present application.
