Description

Technical Field

[0001] This utility model relates to the technical field of automatic air suspension calibration devices, specifically an automatic air suspension calibration device. Background Technology

[0002] In simple terms, suspension is the general term for the connection device between the vehicle body and the wheels. It consists of shock absorbers, guiding mechanisms, and elastic elements. Air suspension, broadly speaking, is a suspension that uses air springs as the elastic element. An air suspension system generally consists of air springs, shock absorbers, guiding structures, air supply units (such as air compressors, one-way valves, air lines, air tanks, etc.), and height control valves. Generally, by controlling the air compressor and exhaust valve, the springs and airbags are automatically compressed or extended, thereby lowering or raising the chassis ground clearance to increase high-speed vehicle stability or passability in complex road conditions. Current air suspension maintenance processes require calibration. However, in actual adjustments, the air suspension may not be automatically adjustable if it is not properly installed or during maintenance, leaving it unable to be calibrated. Furthermore, the suspension itself is relatively heavy, making installation and maintenance inconvenient. Additionally, air suspension is less stable than traditional suspension when the air pump is not working, and may move during installation or inspection, further complicating maintenance. Therefore, we propose an automatic air suspension calibration device to solve these problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides an embodiment of an automatic air suspension calibration device, including a mounting frame 1, on which a mounting block 2 is movably mounted. A T-shaped block is provided on the lower side of the mounting block 2, and a corresponding groove is provided on the upper side of the mounting frame 1, allowing the T-shaped block to slide within the groove.

[0022] A first telescopic motor 3 is fixedly installed at the center of the mounting block 2. A mounting plate 4 is fixedly installed on the output shaft of the first telescopic motor 3. Movable blocks 5 are movably installed on both sides of the mounting plate 4. A receiving block 6 is provided on the movable block 5. A second telescopic motor 7 is fixedly installed on the lower side of the movable block 5. The output shaft of the second telescopic motor 7 is fixedly connected to the receiving block 6.

[0023] The drive mechanism is located on both sides of the mounting block 2 and is used to drive the mounting block 2 to move on the mounting frame 1.

[0024] The unfolding mechanism is set on the mounting plate 4. The unfolding mechanism is used to adjust the distance between the support blocks 6. This structure, through the support blocks 6 that can support the suspension, allows the suspension to be supported without the adjustment system, making maintenance and installation work easier. The position of the support blocks 6 can move on its own, and the distance between the two sets of support blocks 6 can be adjusted, increasing the adaptability of the equipment during use.

[0025] Furthermore, a guide rod 8 is fixedly installed on the lower side of the mounting plate 4, and a guide groove 9 is provided on the mounting block 2. The guide rod 8 is inserted into the guide groove 9. This structure makes the lifting and lowering of the mounting plate 4 more stable and increases the stability of the equipment during use.

[0026] Furthermore, the drive mechanism includes a dual-head motor 10. The dual-head motor 10 is fixedly installed on the left and right sides of the mounting block 2. The lower side of the mounting block 2 does not contact the mounting frame 1. A roller 11 is fixedly installed on the output shaft of the dual-head motor 10. The roller 11 contacts the mounting frame 1. A first gear 13 is fixedly installed on the end of the output shaft of the dual-head motor 10. A rack 12 is fixedly installed on the front and rear sides of the mounting frame 1. The first gear 13 and the rack 12 mesh with each other. This structure allows the mounting plate 4 to move on its own, increasing the functionality of the equipment during use.

[0027] Furthermore, the unfolding mechanism includes a rotary motor 14, which is fixedly installed at the center of the upper side of the mounting plate 4. The mounting plate 4 has a movable groove 15, and two sets of racks 12 are provided in the movable groove 15. The racks 12 are fixedly connected to a set of movable blocks 5 respectively. A second gear 16 is fixedly installed on the output shaft of the rotary motor 14. The second gear 16 meshes with the racks 12. This structure allows the receiving block 6 to unfold relative to each other, so that the receiving block 6 can be adapted to suspensions of different widths, increasing the adaptability of the equipment during use.

[0028] Furthermore, a support bar 17 is fixedly installed on the lower side of the mounting plate 4, and the movable block 5 is placed on the support bar 17 and slides on the support bar 17. This structure makes the receiving block 6 more stable after the spacing is adjusted.

[0029] Furthermore, the receiving block 6 is arc-shaped with protruding edges and rounded corners. This structure allows the receiving block 6 to have a larger contact area with the wheel, making the equipment more stable in supporting the suspension.

[0030] Working principle: When in use, the vehicle is lifted, and the mounting bracket 1 is located under the vehicle. At this time, the dual-head motor 10 is started. The output shaft of the dual-head motor 10 rotates, driving the roller 11 and the first gear 13 to rotate. At this time, the first gear 13 drives the mounting block 2 to move forward through meshing with the rack 12, so that the receiving block 6 is aligned with the wheel. Then, the rotary motor 14 is started, causing the second gear 16 to rotate and drive the movable block 5 to move away from the rack 12 through meshing, so that the receiving block 6 is directly under the wheel. Then, the second telescopic motor 7 is started, causing the receiving block 6 to rise. At this time, the suspension is lifted. The above is the complete working principle of this utility model.
