[0012] Figure 2 It is a structural schematic diagram of the utility model from another viewing angle. DETAILED DESCRIPTION
[0013] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.
[0014] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0015] Example 1
[0016] See also Figure 1 and Figure 2 As shown, an electric baby carriage chassis involved in this embodiment includes a front chassis body 1 and a rear chassis body 2, wherein the front chassis body 1 is provided with a front wheel mounting frame 3, and the rear chassis body 2 is provided with a rear wheel mounting frame 4, and a spring piece 5 arranged in the center is provided between the front chassis body 1 and the rear chassis body 2, wherein the rear end of the spring piece 5 is fixedly connected to the rear chassis body 2, and the front end is rotatably connected to the front chassis body 1;
[0017] The left and right sides of the spring sheet 5 are respectively provided with a support plate 6 extending backward and arranged on the front chassis body. The rear chassis body 2 is provided with a process hole 7 matching the support plate. A movable column 8 arranged on the support plate 6 is arranged in the process hole 7. The front side of the movable column 8 is provided with a matching fixed column 9, and the fixed column 9 is arranged on the rear chassis body 2. The matching movable column 8 and fixed column 9 are covered with a closed ring-shaped elastic ring 10, and the elastic ring 10 is made of rubber material.
[0018] Furthermore, the support plate 6 is closely attached to the bottom of the rear chassis body 2 .
[0019] Furthermore, the support plate 6 is integrated with the front chassis body 1 .
[0020] Furthermore, the sides of the movable column 8 and the fixed column 9 are provided with an annular positioning groove (not shown) for the elastic ring 10 to be partially embedded.
[0021] In this embodiment, due to the connection of the spring sheet 5, the front chassis body 1 can be appropriately tilted up or down relative to the rear chassis body 2; because one end of the spring sheet 5 is rotatably connected to the front chassis body 1 and the other end is fixedly connected to the rear chassis body 2, the front chassis body 1 can also swing left and right relative to the rear chassis body 2.
[0022] By means of the combination of the process hole 7, the movable column 8, the fixed column 9 and the elastic ring 10, the front chassis body 1 which swings left and right can be limited and can be reset in the absence of external force.
