[0014] The specific embodiments of the utility model are described in detail below in combination with the drawings.

[0015] As Figure 1 , 2 , 3, 4, it is the specific embodiment of the utility model side three-wheel anti-rollover rolling type spare wheel structure. The embodiment includes the main vehicle body 1 and the side hopper 2 which are connected to each other, the main tire 3 in the shape of a triangle is formed at the lower part of the main vehicle body 1 and the side hopper 2, the mounting bracket 0 is arranged at the side front of the side hopper 2, the mounting seat 4 is rotatably arranged on the mounting bracket 0, the mounting seat 4 is used for detachably mounting the spare tire 5, when the side three-wheel turns and appears the rollover condition, the spare tire 5 at the side front of the side hopper 2 contacts the ground to roll and support.

[0016] The utility model in use, can be installed on the basis of the conventional existing side three-wheel structure mounting bracket 0 is added, so as to realize the effect of the spare tire 5 front. The dismounting of the spare tire 5 is realized by arranging a rotatable mounting seat 4, the size of the spare tire 5 and the mounting seat 4 is matched to realize cooperation, then the spare tire 5 is disassembled through the fastener, the spare tire 5 after installation can rotate with the mounting seat 4. If the side three-wheel inclines and is about to rollover, the spare tire 5 can be supported on the ground to prevent the side three-wheel from continuing to incline, and the rotatable arrangement of the spare tire 5 allows the side three-wheel to roll naturally in the subsequent running process, reduces the hard impact wear of the structure, and further improves the durability of the structure under the premise of improving the driving safety.

[0017] As an improved specific embodiment, the mounting seat 4 includes the rear seat 41 and the shaft body 42 arranged at the front part of the rear seat 41, the spare tire 5 is sleeved on the shaft body 42, the threaded hole corresponding to the fastener mounting hole 51 on the spare tire 5 is arranged at the rear seat 41, and the spare tire 5 is mounted on the rear seat 41 through the fastener.

[0018] As Figure 1 , 2As shown, the size of the shaft body 42 is fitted with the inner diameter of the hub inner ring of the spare tire 5, and the rear side of the hub is limited by the rear seat 41. The fastener mounting hole 51 on the hub corresponds to the threaded hole on the rear seat 41, and then the structure is locked by manually installing fasteners such as screws, which ensures that the spare tire 5 is installed firmly while allowing it to rotate stably with the mounting seat 4.

[0019] As an improved embodiment, the mounting bracket 0 includes a wheel shaft 01, a bearing is arranged on the wheel shaft 01, and the mounting seat 4 is sleeved on the wheel shaft 01 and limited at the outer end by a fastener.

[0020] As shown in Figure 3 , 4 , the wheel shaft 01 extends outwardly to provide space for the mounting seat 4 and the shaft structure. The mounting seat 4 is supported on the bearing after being sleeved on the wheel shaft 01, and can rotate smoothly. The mounting seat 4 is blocked by a fastener such as a nut installed at the outer end of the wheel shaft 01 to achieve stable installation of the structure. When the mounting seat 4 needs to be replaced, it can be disassembled, facilitating the replacement of parts such as new or different specifications of the mounting seat 4, and further adapting to the installation of different specifications of the spare tire 5.

[0021] As an improved embodiment, the mounting bracket 0 further includes an upper pipe bracket 02, a lower pipe bracket 03 and a layout plate 04. The upper pipe bracket 02 and the lower pipe bracket 03 are arranged in front of the side of the bucket 2 and extend forward and backward. The layout plate 04 is connected between the upper pipe bracket 02 and the lower pipe bracket 03, and one end of the wheel shaft 01 is arranged on the layout plate 04.

[0022] As shown in Figure 3 , 4 , the lower pipe bracket 03 extends forward and backward below the lower edge of the bucket 2, and the upper pipe bracket 02 extends forward and backward above the lower pipe bracket 03. The two cooperate to form a space structure, which is further connected between the upper pipe bracket 02 and the lower pipe bracket 03 by the layout plate 04 to form a bracket structure for the wheel shaft 01. The inner side of the wheel shaft 01 is arranged on the layout plate 04, and the wheel shaft 01 extends outwardly as a whole to provide a space for the mounting seat 4. The above structure allows the spare tire 5 to be installed and arranged in front of the side of the bucket 2 without interference and without affecting the access of the passengers behind the bucket 2.

[0023] As an improved embodiment, the upper pipe bracket 02 forms an angle with respect to the bucket 2, and the wheel shaft 01 on the layout plate 04 is directed towards the front side, and the spare tire 5 forms an angle with respect to the main vehicle body 1.

[0024] As shown in Figure 1 , 3As shown in FIGS. 1, 2, 3 and 4, the angle setting mode of the upper pipe frame 02 makes the arrangement plate 04 and the wheel shaft 01 face the side front of the sidecar 2, and further makes the mounting seat 4 and the spare tire 5 face the side front after installation, that is, the spare tire 5 is not parallel to the other direction-fixed main tire 3, and it can be well arranged along the outer contour of the vehicle body at the side front of the sidecar 2, and the structure is not conspicuous, and it is beneficial to the storage of the spare tire 5 at the side front; when the tilt occurs, the side three-wheeler tilts towards the position of the spare tire 5, and the spare tire 5 can well provide support and roll in the process of the continuous travel of the side three-wheeler, and the side three-wheeler will not be rolled over.

[0025] The preferred embodiments of the present application have been described above, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the technical field, some improvements and decorations without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
