[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] To better understand the technical solutions shown in the embodiments of this application, the working principle of the existing enclosed tricycle chassis support device will be introduced first.

[0021] Existing tricycle chassis support structures are mostly welded trestles, iron frames, hydraulic cylinders, etc., used to support the three positions of the tricycle chassis separately. During loading, unloading, and moving, when encountering different models of chassis, the position and height need to be adjusted separately, which wastes a lot of time. In addition, the brackets for each support position need to be carried separately when moving, which takes a long time to adjust and the connection is unstable, resulting in a mess in the workshop. Therefore, it is necessary to improve the existing support structure, and the design scheme of this application is proposed.

[0022] Please see Figures 1 to 3 This application discloses a closed-type tricycle chassis support device, comprising: a mounting frame 1, a connecting notch 2, a support arm 3, a pin 4, a bearing seat 5, a slide groove 6, a connecting rod 7, a guide groove 8, a slide rod 9, a connecting frame 10, an electric telescopic rod 11, a positioning hole 12, a connecting rod 13, a connecting seat 14, a guide rod 15, a sliding block 16, an electric push rod 17, and a movable frame 18. The mounting frame 1 is rectangular in shape, the connecting notch 2 is located at the middle of one end of the mounting frame 1, and the support arm 3 is through the middle. The lower end of the support arm 3 is movably connected to the connecting notch 2 via a pin 4. The bearing seat 5 is connected to the other end of the support arm 3. The slide groove 6 is opened at the middle position on both sides of the through part in the middle of the support arm 3, and the slide groove 6 is equidistantly arranged with connection points. One end of the connecting rod 7 is rotatably connected to a connection point at a certain position of the slide groove 6. The guide groove 8 is symmetrically opened through the side of the mounting frame 1 near the connecting notch 2. The two ends of the slide rod 9 are slidably connected to the guide groove 8, and the other end of the connecting rod 7 is movably connected to the middle of the slide rod 9. The positioning hole 1 2. Equivalent through-holes are opened on both sides of the mounting frame 1 at the end away from the connecting notch 2. The two ends of the connecting rod 13 are fastened to the corresponding positioning holes 12 on both sides. The connecting frame 10 is U-shaped. The two ends of the connecting frame 10 are respectively connected to the two sides of the sliding rod 9. One end of the electric telescopic rod 11 is fixedly connected to the middle of the connecting frame 10, and the other end of the electric telescopic rod 11 is fixedly connected to the middle of the connecting rod 13. The connecting seat 14 is symmetrically fixedly connected to the upper surface of the two sides of the mounting frame 1 at the side away from the connecting notch 2. The guide rod 15 Two guide rods 15 are provided, with both ends fixedly connected to the connecting seat 14. Two sliding blocks 16 are provided, which are symmetrically slidably connected to the guide rods 15. The upper surface of the middle part of the sliding block 16 is concave downward. The lower end of the electric push rod 17 is fixedly connected to the concave position in the middle of the sliding block 16. The movable frame 18 has an inverted U-shape in appearance. The two sides of the movable frame 18 are slidably connected to the two sides of the sliding block 16. The upper end of the electric push rod 17 is fixedly connected to the middle position of the lower end of the movable frame 18.

[0023] Specifically, the mounting frame 1 provides a support and connection base, with its width and length exceeding the maximum dimensions of commonly used tricycles under current national standards. The connection notch 2 is used to connect the support arm 3. During use, adjusting the position of the connecting rod 13 at the positioning hole 12 allows for adjustment of the highest possible position of the support arm 3. Adjustment is made when the required support point exceeds the maximum. During adjustment, the electric telescopic rod 11 extends or retracts, pushing the connecting frame 10. The two sides of the connecting frame 10 smoothly push the sliding rod 9. The movement of the sliding rod 9 pushes the lower end of the connecting rod 7. Since the upper end of the connecting rod 7 is rotatably connected to a position in the sliding groove 6, the support arm 3 is lifted, providing support. The upper end of arm 3 drives the support seat 5 to rise or fall. The support seat 5 is movably connected and can support the upper plane at different angles. The pin 4 allows for easy disassembly. The guide rod 15 on the connecting seat 14 allows the sliding block 16 to move on it, making it easy to adapt to the support of tricycle chassis of different widths. When the electric push rod 17 extends or retracts, the movable frame 18 can rise and fall accordingly. The two sides of the movable frame 18 are slidably connected to the two sides of the sliding block 16, making its rise and fall more stable. The upper end of the movable frame 18 is used to support the two sides of the chassis of tricycles of different widths, realizing rapid assembly and production. Compared with the existing welded bracket, it greatly improves production efficiency and reduces costs, and has good practicality.

[0024] Please see Figure 1 As another specific embodiment provided in the application, it also includes a cushioning pad 19, which is fixedly connected to the upper surface of the movable frame 18 and the support seat 5 respectively.

[0025] Specifically, the cushioning pad 19 protects the area under the chassis from surface damage during placement and lifting.

[0026] Please see Figure 1 As another specific embodiment provided in the application, it also includes scale lines 20, which are equidistantly opened on the upper surface of the mounting frame 1 corresponding to the guide groove 8.

[0027] Specifically, the setting of scale line 20 allows for a more intuitive observation of the adjustment position of slider 9, improving the convenience of use.

[0028] Please see Figure 1 As another specific embodiment provided in the application, it also includes a limiting sleeve 21, which is disposed on the slide rods 9 on both sides of the lower end of the connecting rod 7.

[0029] Specifically, the limiting sleeve 21 can limit the lower end of the connecting rod 7, so that its position does not change during movement, thus improving stability during use.

[0030] Please see Figure 3 As another specific embodiment provided in the application, it also includes a mounting base 22, which is fixedly connected in a ring array to the lower end surface inside the mounting frame 1.

[0031] Specifically, the mounting base 22 is designed to connect and fix the mounting frame 1, ensuring that it is securely installed on the ground or other construction platform, thus guaranteeing stable production.

[0032] Please see Figure 2 As another specific embodiment provided in the application, it also includes connecting holes 23, which are equidistantly opened on both sides of the movable frame 18.

[0033] Specifically, the connection hole 23 can be used to connect other auxiliary or cooperating related components, making the support more flexible and meeting the needs of actual scenarios.

[0034] Please see Figure 1 As another specific embodiment provided in the application, it also includes a control switch group 24, which is fixedly connected to the surface of one side of the mounting frame 1. The input end of the control switch group 24 is electrically connected to the output end of an external power supply, and the output end of the control switch group 24 is electrically connected to the input ends of the electric telescopic rod 11 and the electric push rod 17, respectively.

[0035] Specifically, the control switch group 24 enables separate control of the electric telescopic rod 11 and the electric push rod 17, which greatly improves convenience compared to manual operation and helps to speed up production.
