Technical Field

[0001] The utility model relates to the field of vehicle sensors, in particular to a vehicle sensor calibration device. Background Art

[0002] Vehicle sensors are vital electronic components in cars. They are responsible for monitoring the various operating conditions and external environment of the vehicle, converting the collected information into electrical signals, and then transmitting them to the car's electronic control unit for processing.

[0003] During the sensor calibration process, when the position of the sensor needs to be precisely controlled or moved along a specific trajectory, the sensor is moved by a manual push device. However, the force applied by the human hand is difficult to maintain constant. Slight changes in force or directional deviations will affect the movement trajectory of the sensor, resulting in position deviations. If manual precision operations are performed for a long time, people will easily feel tired. Brief distractions in attention may also lead to operational errors, affecting the quality of sensor calibration and, in turn, the accuracy of the calibration data.

[0004] In view of the above problems, it is necessary to design a vehicle sensor calibration device. Utility Model Content

[0008] Furthermore, it is particularly preferred that the splint is semi-arc shaped.

[0009] In addition, it is particularly preferred that a mounting hole is provided on the base.

[0010] Furthermore, it is particularly preferred that the number of special plates is not less than two.

[0011] In addition, it is particularly preferred that sliding grooves are symmetrically provided inside the placement rack.

[0012] The beneficial effects of the utility model are as follows: the slider is driven to move by the electric slide rail, and the slider drives all the components thereon to move, so that during the movement of the sensor, it can be determined whether the presence of the protrusion and the square groove can be sensed, thereby judging whether the sensor calibration is up to standard; the placement rack and the sensor are driven to move by the electric push rod, and the height of the sensor can be adjusted, so as to observe whether it can sense the presence of the protrusion and the square groove according to the adjusted position of the sensor, and then judge whether the change in position height indicates that the sensor calibration is up to standard.

DETAILED DESCRIPTION

[0018] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0019] Embodiment: Vehicle sensor calibration device, such as Figure 1-Figure 4As shown, it includes a base 1, an electric slide rail 2, a slider 3, a placement rack 4, a limit plate 41, an electric push rod 42, a sensor 5, a special plate 6, a bump 7, a mounting plate 9, a pull rod 10, an elastic member 11, a clamping plate 12, a guide block 13, a data recording device 14 and a display screen 15. The base 1 is provided with a mounting hole, the base 1 is provided with an electric slide rail 2, the electric slide rail 2 is slidably connected with a slider 3, the slider 3 is connected with a limit plate 41, the front side of the limit plate 41 is provided with an electric push rod 42, the telescopic end of the electric push rod 42 is connected with a placement rack 4, the placement rack 4 is slidably matched with the limit plate 41 for placing the sensor 5, the placement rack 4 is symmetrically provided with a slide groove inside, the placement rack 4 is provided with a sensor 5, the base 1 is symmetrically connected with special plates 6, the number of the special plates 6 is not less than two, the inner side of the special plate 6 is connected with a bump 7, the special plate 6 is provided with a square groove 8, the placement rack 4 is provided with a mounting The plate 9 is used to support the pull rod 10. The pull rod 10 is slidably connected to the middle part of the mounting plate 9. The lower part of the pull rod 10 is connected to a guide block 13. The guide block 13 is slidably connected to the placement frame 4, so that when the pull rod 10 is pulled to move, the guide block 13 can guide it. An elastic member 11 is connected between the upper side of the guide block 13 and the lower side of the mounting plate 9. The elastic member 11 is a compression spring. A clamping plate 12 is connected to the lower part of the guide block 13. The clamping plate 12 is semi-arc-shaped. The semi-arc-shaped clamping plate 12 can better fit the surface of the sensor 5 and fix it. A data recording device 14 is installed on the front side of the base 1. The connecting line of the sensor 5 is electrically connected to the data recording device 14, which can receive the signal sent by the sensor 5 and transmit the received data. A display screen 15 is installed on the data recording device 14. The display screen 15 is electrically connected to the data recording device 14 and can display the received data.

[0020] When the device needs to be used, the staff pulls the pull rod 10 to drive the guide block 13 and the clamping plate 12 to move upward along the placement rack 4, and the elastic member 11 is compressed. When the clamping plate 12 moves to a suitable position, the connecting line of the sensor 5 is connected to the data recording device 14, and then the connected sensor 5 is placed on the placement rack 4. After the sensor 5 is placed, the pull rod 10 is released again. Under the resetting action of the elastic member 11, the clamping plate 12 drives the guide block 13 and the pull rod 10 to move downward along the placement rack 4. The clamping plate 12 moves to contact with the sensor 5 and fixes it. Since the initial state of the connected sensor 5 is in the closed state, the sensor 5, the data recording device 14 and the display screen 15 are started again, and then the electric slide rail 2 is started. The rail 2 drives the slider 3 and all the components thereon to move backward. When the sensor 5 moves between the two special plates 6, the sensor 5 senses the existence of the protrusion 7 and sends a signal, and then transmits the sensed data. The data recording device 14 receives the data and transmits the data to the display screen 15, which is convenient for the staff to view the received data through the display screen 15. Then the sensor 5 continues to move backward. When the sensor 5 senses the existence of the square groove 8, it sends a signal again and transmits the sensed data. The data recording device 14 receives the data again and transmits the data to the display screen 15, which indicates that the sensor 5 is calibrated to meet the standard. If the sensor 5 cannot sense the protrusion 7 and the square groove 8 during its movement, The existence of the shaped groove 8 indicates that the calibration of this sensor 5 does not meet the standard. Then the electric slide rail 2 drives the slider 3 and all the components thereon to move forward back to the original position, and then repeats the above-mentioned operation of pulling the pull rod 10, so that the clamping plate 12 moves and disengages from the sensor 5, and then the sensor 5 that does not meet the standard is removed. After the sensor 5 that does not meet the standard is removed, a new sensor 5 is placed on the placement rack 4. During the calibration process of the sensor 5, when it is necessary to adjust the height of the sensor 5, the staff starts the electric push rod 42, and the telescopic end of the electric push rod 42 drives the placement rack 4 and the sensor 5 to move upward along the limit plate 41. When the sensor 5 moves to a suitable height, the electric push rod 42 is closed, and the electric slide rail 2 drives the slider 3 to move backward again, and the slider 3 drives the upper All parts move backwards, and when the sensor 5 moves, it senses the existence of the protrusion 7 and the square groove 8 and sends a signal. At the same time, the sensed data is transmitted, so that the data recording device 14 receives the signal and transmits the data to the display screen 15, indicating that after the height of the sensor 5 is adjusted, it can still sense the existence of the protrusion 7 and the square groove 8, which means that the calibration of the sensor 5 after the height adjustment is up to standard. If the sensor 5 cannot sense the existence of the protrusion 7 and the square groove 8 during the movement of the sensor 5, it means that the calibration of the sensor 5 after the height adjustment is not up to standard. Repeat the above operation. When the calibration operation of the sensor 5 is completed, the electric slide rail 2, the sensor 5, the data recording device 14 and the display screen 15 are closed.

[0021] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
