Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] Example 1:

[0035] This application discloses a chassis structure for a car, referring to... Figure 1 , Figure 2 The system includes a support frame 1 and a support plate 2 fixedly connected to the upper surface of the support frame 1. The support frame 1 includes a pair of side beams 11 spaced apart and a rear beam 12 fixedly connected between the rear ends of the two side beams 11. In this embodiment, both the side beams 11 and the rear beam 12 are made of channel steel, and the slots of both the side beams 11 and the rear beam 12 are arranged facing outwards.

[0036] Reference Figure 2 , Figure 3 The upper end face of the side beam 11 is fixedly connected to the lower end face of the support plate 2, and the upper end face of the rear beam 12 is fixedly connected to the lower surface of the rear side of the support plate 2. A front baffle 22 is fixedly connected to the lower front surface of the support plate 2. The front baffle 22 is vertically arranged, and a support edge plate 23 is fixedly connected to the lower rear side wall of the front baffle 22. In this embodiment, the support plate 2, the front baffle 22, and the support edge plate 23 are integrally formed and fixed. The lower front end face of the side beam 11 is fixedly connected to the upper end face of the support edge plate 23, and the front end face of the side beam 11 is fixedly connected to the surface of the front baffle 22.

[0037] A water receiving trough 3 located inside the support frame 1 is fixedly connected to the lower end face of the support plate 2. In this embodiment, the upper part of the water receiving trough 3 is open. The water receiving trough 3 includes a pair of side troughs 31 spaced apart and a rear trough 32 fixedly connected between the rear ends of the two side troughs 31. The inner cavity of the rear trough 32 communicates with the inner cavity of the side troughs 31. The side troughs 31 are fixedly connected to the side walls of the adjacent side beams 11. The rear trough 32 is fixedly connected to the front outer wall of the rear beam 12. (Refer to...) Figure 1 The upper end face of the support plate 2 is provided with a water-permeable hole 21 that is connected to the inner cavity of the water receiving tank 3. Multiple water-permeable holes 21 are provided.

[0038] Reference Figure 4The water receiving tank 3 is equipped with a drainage assembly 4, which includes a drain pipe 41 fixedly passing through the bottom wall of the side tank 31 and a water guide pipe 42 fixedly passing through the bottom side wall of the elevator shaft. The drain pipe 41 is vertically arranged and is equipped with a control component for controlling the opening and closing of the drain pipe 41, specifically, a solenoid valve 43. One end of the water guide pipe 42 is fixedly connected to a connecting pipe 44 built into the elevator shaft. The connecting pipe 44 is vertically arranged, and the drain pipe 41 slides vertically and is inserted into or sleeved on the connecting pipe 44. In this embodiment, when the drain pipe 41 moves down to the lowest position, the drain pipe 41 is inserted into the connecting pipe 44. The other end of the water guide pipe 42 is externally connected to a drainage channel or a water storage tank.

[0039] A limit switch 13 is fixedly connected to the lower end face of one side beam 11. Specifically, the limit switch 13 can be a heavy-duty lever roller type limit switch or a push-button type limit switch, and the limit switch 13 is electrically connected to the solenoid valve 43. An actuating block 10 is fixedly connected to the inner wall of the elevator shaft. When the support frame 1 moves down to the lowest point, the actuating block 10 abuts against the limit switch 13, and the solenoid valve 43 controls the drain pipe 41 to open. When the support frame 1 moves up and the actuating block 10 disengages from the limit switch 13, the solenoid valve 43 controls the drain pipe 41 to close. In other embodiments, the solenoid valve 43 can be controlled to open and close by an external control device, thereby controlling the opening and closing of the drain pipe 41.

[0040] The implementation principle of the chassis structure of the car in this embodiment is as follows: multiple water-permeable holes 21 on the support plate 2 allow water in the car to flow into the water receiving tank 3, reducing the possibility of water accumulation on the upper surface of the car chassis. When the support frame 1 moves down to the bottom, the trigger block 10 abuts against the limit switch 13, the drain pipe 41 connects with the connecting pipe 44, and the solenoid valve 43 controls the drain pipe 41 to open, realizing automatic control of drainage of the water receiving tank 3, improving the convenience and reliability of drainage. When the trigger block 10 disengages from the limit switch 13, the solenoid valve 43 closes the drain pipe 41, effectively preventing the drain pipe 41 from draining during the car's ascent.

[0041] Example 2:

[0042] The difference from Example 1 is that, referring to Figure 5 A reinforcing rod 33 is fixedly connected between the two side grooves 31. Multiple reinforcing rods 33 are provided and distributed along the length direction of the side grooves 31. The upper end face of the reinforcing rod 33 abuts against the lower end face of the support plate 2.

[0043] Example 3:

[0044] The difference from Example 1 is that, referring to Figure 6 , Figure 7The water receiving tank 3 is a square tank. The outer walls of the two sides of the water receiving tank 3 are fixedly connected to the side walls of the two side beams 11 that are close to each other. The upper end face of the water receiving tank 3 is fixedly connected to the lower end face of the support plate 2. The rear outer wall of the water receiving tank 3 is fixedly connected to the side wall of the rear beam 12. The inner wall of the water receiving tank 3 is fixedly connected to a grid plate 34 with cross-shaped horizontal and vertical lines. The upper end face of the grid plate 34 abuts against the lower end face of the support plate 2, and the lower end face of the grid plate 34 is located above the bottom inner wall of the water receiving tank 3.
