[0002] Suspension is the general term for all force-transmitting connection devices between the frame (or load-bearing body) and the axle (or wheel) of a car. Its function is to transmit the force and torque acting between the wheel and the frame, and to buffer the impact force transmitted to the frame or body by the uneven road surface, and reduce the vibration caused thereby, so as to ensure that the car can run smoothly. During the production or maintenance of the car, the suspension of the car needs to be leveled or tested. At this time, the distance between the suspension and the ground needs to be measured. The traditional manual measurement method has low accuracy, and the measured data needs to be compared. The error of the compared data will be further expanded. In addition, during the process of adjusting the suspension, if the height of the suspension from the ground changes, it needs to be re-measured, which is troublesome.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides an embodiment: a height sensor for automobile suspension, comprising a mounting base plate 1, two sets of mounting base plates 1, and a mounting block 2 is movably mounted on the mounting base plate 1.

[0022] A loading cylinder 3 is fixedly mounted on the mounting block 2, a screw rod 4 is movably inserted in the loading cylinder 3, a movable rod 5 is movably inserted at the upper end of the screw rod 4, a mounting column 6 is fixedly mounted on the upper end of the movable rod 5, a laser transmitter 7 is fixedly mounted on the left mounting column 6, a laser receiver 8 is arranged on the right mounting column 6, and the laser transmitter 7 is opposite to the laser receiver 8;

[0023] An adjusting mechanism, which is arranged at the loading cylinder 3 and is used to adjust the height of the mounting column 6;

[0024] The movable mechanism is arranged at the movable rod 5, and the movable mechanism provides a movable space for the mounting column 6. The device can directly obtain the height difference between the automobile suspensions through the induction between the laser transmitter 7 and the laser receiver 8, thereby increasing the accuracy of the data. The device is also provided with a movable mechanism, which can adapt to the situation of the suspension height adjustment, and the mounting column 6 can be manually adjusted in height, thereby increasing the adaptability of the device when it is used;

[0025] Furthermore, the laser transmitter 7 is aligned with the center position of the laser receiver 8, and the outer side of the laser receiver 8 protrudes outward. This structure allows the device to adapt to the up and down movement of the suspension, and makes the laser receiver 8 less susceptible to external interference when receiving the laser.

[0026] Furthermore, a slide groove 9 is opened on the mounting base plate 1, and a support block 10 is fixedly installed on the lower side of the mounting block 2. The shape of the slide groove 9 is adapted to the shapes of the mounting block 2 and the support block 10. The height of the slide groove 9 is higher than the height of the support block 10. This structure enables the device to use the mounting base plate 1 for guidance during detection, so that the two groups of loading cylinders 3 are on the same horizontal line, which increases the convenience of using the device.

[0027] Furthermore, a damping rubber pad 11 is fixedly installed on the lower side end of the support block 10, and a stop block 12 is fixedly installed on the upper end of the mounting column 6. This structural mounting block 2 can be stably placed alone, and at the same time, the contact area with the suspension is larger, which increases the stability of the equipment when in use.

[0028] Furthermore, the adjustment mechanism includes a guide groove 13, a guide groove 13 is opened in the screw 4, a guide block 14 is fixedly installed in the loading cylinder 3, a screw sleeve 15 is rotatably installed on the upper end of the loading cylinder 3, and the screw sleeve 15 is threadedly connected to the screw 4. As a result, the height of the mounting column 6 can be adjusted, thereby increasing the adaptability of the equipment when used.

[0029] Furthermore, the movable mechanism includes a movable groove 16, a movable groove 16 is opened at the upper end of the screw rod 4, the movable rod 5 is movably installed in the movable groove 16, a spring 17 is fixedly installed in the movable groove 16, the spring 17 is against the movable groove 16, and a limiting block 18 is fixedly installed on the left and right sides of the lower end of the movable rod 5. A limiting groove 19 is opened in the movable groove 16, and the limiting block 18 slides in the limiting groove 19. This structure allows the mounting column 6 to move when subjected to force, so that the equipment can adapt to the height adjustment of the suspension, thereby increasing the adaptability of the equipment when in use.

[0030] Working principle: When in use, insert the mounting block 2 into the slide groove 9, then move it to a suitable position, and then rotate the screw sleeve 15. Through the threaded action between the screw sleeve 15 and the screw rod 4, the guide block 14 rises under the guidance of the guide groove 13 and the guide block 14, so that the stop block 12 can stop at the lower side of the suspension. At this time, the laser emitted by the laser transmitter 7 will be received by the laser receiver 8. The height of the laser irradiation fed back by the laser receiver 8 can be read to calculate the height difference between different suspensions. When adjusting the suspension height, the movable rod 5 will move in the movable groove 16 and compress the spring 17. At this time, the limit block 18 slides in the limit groove 19 to adapt to the adjustment of the suspension, especially the separate adjustment of the air suspension, so that the adjusted suspension does not need to be measured, and the data fed back by the laser receiver 8 can be directly read. The above is the entire working principle of the utility model.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
