[0018] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Refer to the instruction manual appendix Figures 1-5 This utility model provides a tram frame that facilitates changing the tilt angle, including a frame body 1. The frame body 1 is provided with auxiliary components to improve operability. The auxiliary components include two foot support brackets 2, which are respectively located on both sides of the frame body 1, and the top of the foot support brackets 2 is rotatably connected to the frame body 1. The auxiliary components enhance the stability of the frame body 1 through a linkage component.

[0020] By installing two rotatably connected foot brackets 2 on the outside of the frame body 1, users can tilt the vehicle in two directions when parking, which can effectively improve the convenience of parking the vehicle. Users can park in multiple positions as needed, avoiding the need to adjust the vehicle's orientation due to an unsuitable parking position, thereby improving the practicality of this product.

[0021] Meanwhile, to ensure the stability of the vehicle when parked, it is necessary to increase the weight of the vehicle when tilted. This can be achieved by first installing a water tank on the frame body 1, and then connecting it to the water tank via a linkage mechanism. The linkage mechanism includes a water pipe 3 located at the bottom of the frame body 1. The water pipe 3 has a U-shaped cross-section, and a connecting pipe 4 is fixedly connected to its rear end. A one-way valve 5 is installed on the front end of the connecting pipe 4. This allows water from the water tank to be transported to the water pipe 3 via the connecting pipe 4. When the frame body 1 is tilted, the water in the water pipe 3 automatically flows to the tilted end of the water tank by gravity, thereby increasing the weight of the frame body 1 when tilted and enhancing its stability, preventing the frame body 1 from tilting or tipping over due to external impacts.

[0022] To ensure the stability of the connection between the water pipe 3 and the frame body 1, connectors for connecting the frame body 1 are provided on the outside of both ends of the water pipe 3. Each set of connectors includes two connecting brackets 6, which are fitted onto the outside of the water pipe 3, with the top of the connecting bracket 6 extending to the outside of the frame body 1. In this way, the water pipe 3 can be fitted onto the outside of the frame body 1 through the connecting brackets 6, and the water pipe 3 and the frame body 1 are connected as one unit by the connecting brackets 6.

[0023] Furthermore, to prevent the water pipe 3 from becoming loose, fastening bolts 10 are provided on both sides of the top of the connecting frame 6. The fastening bolts 10 pass through the connecting frame 6 and extend into the interior of the frame body 1, and are threadedly connected to the frame body 1. In this way, the connecting frame 6 can be fixed to the outside of the frame body 1 with the help of the fastening bolts 10, thereby enhancing the tightness of the connection between the connecting frame 6 and the frame body 1 and preventing the connecting frame 6 from becoming loose or detached.

[0024] Meanwhile, to prevent the water inside the water pipe 3 from freezing in the low temperatures of winter, insulation cylinders 7 are installed on both ends of the water pipe 3. Heating wires 8 are installed inside the insulation cylinders 7 and are fitted onto the outside of the water pipe 3. This allows the heating wires 8 to heat the water pipe 3, preventing the water from freezing and ensuring water flow. Furthermore, the insulation cylinders 7 seal the heat from the heating wires 8, ensuring effective heating of the water pipe 3.

[0025] Furthermore, a fixing plate 9 is installed between the two corresponding connecting frames 6 at the front and rear. The fixing plate 9 is vertically aligned with the insulation cylinder 7, and the bottom end of the fixing plate 9 is fixed to the top of the insulation cylinder 7. This allows the insulation cylinder 7 to connect to the two corresponding connecting frames 6 at the front and rear with the help of the fixing plate 9, thereby ensuring the supporting strength of the fixing plate 9, preventing the fixing plate 9 from becoming loose, and thus effectively ensuring the stability of the insulation cylinder 7.

[0026] To ensure the integrity of the water pipe 3 and other structures, protection is required. Therefore, a common mounting bracket 11 is installed at the bottom of the two corresponding connecting frames 6. The tops of the front and rear ends of the mounting bracket 11 are fixed to the bottoms of the two connecting frames 6, and multiple spaced protective strips 12 are installed between the two mounting brackets 11. The protective strips 12 are made of rubber. In this way, the bottom of the water pipe 3 is protected by multiple protective strips 12, preventing flying debris from impacting the water pipe 3 and other structures. Furthermore, the rubber material of the protective strips 12 helps to buffer the impact of flying debris, preventing impact noise from affecting driving comfort.

[0027] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
