[0021] In order to make the purpose, technical scheme and advantages of the utility model embodiment more clear, the utility model technical scheme will be described clearly and completely in combination with examples.

[0022] Example 1

[0023] As shown in the drawing, Figure 1 The sightseeing vehicle with the aluminum alloy car body includes a car body frame, and the car body frame adopts an aluminum alloy material.

[0024] The sightseeing vehicle with the aluminum alloy car body in the technical scheme adopts the aluminum alloy material for the car body frame, greatly reduces the self quality of the whole vehicle, thereby realizing the effect of guaranteeing the endurance of the vehicle.

[0025] Meanwhile, the aluminum alloy car body frame has the strength required by the sightseeing vehicle, makes the sightseeing vehicle have higher fatigue strength, plasticity and corrosion resistance.

[0026] Because the sightseeing vehicle in this technical solution uses aluminum alloy for its frame, and aluminum alloy has a large coefficient of thermal expansion, it may cause dimensional changes at high temperatures, affecting the vehicle's assembly precision. Furthermore, aluminum alloy is prone to defects such as pinholes and bubbles during welding, and different types of aluminum alloys exhibit metallurgical incompatibility, making welding difficult. Therefore, if... Figure 2 , Figure 3 As shown, the sightseeing vehicle with an aluminum alloy body uses a combination of welding and screw connections between the beams of the body frame. This reduces the welding area and the use of screw assembly allows for adjustments to the assembly position to mitigate the impact of temperature on the vehicle's assembly accuracy.

[0027] Furthermore, the screw connection is achieved using a screw assembly assembly, which includes a first plate 11 and two second plates 21. The first plate 11 and the second plate 21 are respectively connected to two beams that need to be connected. In this embodiment, the first plate 11 and the second plate 21 are suitable for connecting beams that are parallel to each other. Meanwhile, in other embodiments, the first plate 11 and the second plate 21 can be shaped according to usage requirements, for example, they can be adjusted to an L-shape, which is suitable for connecting beams that are perpendicular to each other.

[0028] Two plates 21 are connected to the same housing 23 via outer plates 22. Plate 11 is connected to an inner plate 12. The movable end of the inner plate 12 extends into the housing 23 and is connected to an inner plate 13. A strip-shaped hole 14 is provided on the inner plate 13 along its length. A screw 31 passes through the strip-shaped hole 14. To facilitate the rotation of the screw 31, a slot, such as a plum blossom slot or a cross slot, can be provided at the lower end of the screw 31. The screw 31 is rotatably engaged with the bottom wall of the housing 23. A nut 32 is threaded onto a section of the screw 31 between the inner plate 13 and the bottom wall of the housing 23. The nut 32 is slidably engaged with the inner wall of the housing 23 along the length of the screw 31. When the screw 31 rotates in the forward direction, it drives the nut 32 to move towards the inner plate 13. When the screw 31 rotates in the reverse direction, it drives the nut 32 to move towards the housing 23.

[0029] In this technical solution, the total length of the two plates 11 and 21 is adjusted according to the distance between the beams to be connected. The plates 11 and 21 are then connected to the beams to be connected. The screw 31 is rotated to move the nut 32 until the housing 23, inner plate 13, and nut 32 are in close contact, thus fixing the relative position of the plates 11 and 21. The assembly position of the screw assembly assembly can be adjusted to adapt to the assembly distance of the vehicle connecting beams.

[0030] To improve assembly stability, such as Figure 2 , Figure 3As shown, both ends of the screw 31 penetrate the housing 23. A nut 34 is threaded onto a section of the screw 31 between the plate 21 and the housing 23. The nut 34 slides with the outer plate 22 along the length of the screw 31. When the screw 31 rotates in the forward direction, it moves the nut 34 toward the plate 11. When the screw 31 rotates in the reverse direction, it moves the nut 34 toward the housing 23. As the screw 31 rotates, it moves the nut 32. When the housing 23, the inner plate 13, and the nut 32 come into close contact, the screw 31 rotates synchronously, moving the nut 34. This results in the plate 11, the plate 21, and the nut 34 coming into close contact, increasing the contact area and improving the stability of the assembly.

[0031] To address the issue of a sliding fit between the nut 32 and the inner wall of the housing 23 along the length of the screw 31, as follows: Figure 2 , Figure 3 As shown, nut 32 is connected to slider 33, which slides in a groove on housing 23; to solve the sliding fit between nut 34 and outer plate 22 in the length direction of screw 31, nut 34 is connected to slider 35, which slides in a groove on outer plate 22.

[0032] To further improve assembly stability, such as Figure 3 As shown, there are two sets of combined structures of strip hole 14, screw 31, nut 1 32, slider 1 33, nut 2 34 and slider 2 35; at the same time, in order to improve the convenience of operation, a connecting rod 36 is connected between the two sets of nut 1 32. When one of the screws 31 is rotated, the other screw 31 will rotate accordingly, ensuring the synchronicity of the assembly of the combined structure of the two sets of screws 31.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
