[0002] When loading goods, the vehicle needs to be monitored by a driving electronic scale to avoid overloading due to heavy goods. The working principle of the driving electronic scale is: the change of strain on the mechanical component is converted into resistance change through the resistance strain gauge, so that the impedance changes, and the excitation voltage changes at the same time, and a changing analog signal is output. The signal is amplified by the amplifier circuit and output to the analog-to-digital converter, which is converted into a digital signal for easy processing and output to the CPU for operation control. The CPU outputs the result to the display according to the keyboard command and the program until the result is displayed.

[0003] The existing electronic scale for monitoring driving safety is difficult to install when in use, and the electronic scale is easy to fall off when the vehicle is driving. In view of this, we propose an electronic scale for monitoring driving safety. Utility Model Content

The sliding of the sliding block drives the mounting plate to fit the outer wall of the frame. By setting anti-slip grooves, it is beneficial to improve the stability of the connection between the mounting plate and the frame. At the same time, the movement of the mounting plate drives the resistance strain gauge to fit closely with the outer wall of the frame, thereby realizing the fast and stable installation operation of the electronic scale body.

[0008] Preferably, two groups of connecting plates are provided, and the two groups of connecting plates are symmetrical with respect to the connecting slider. During operation, by providing two groups of connecting plates, the connecting slider slides and drives the two groups of connecting plates to move synchronously, so as to facilitate the detection of the deformation amount on both sides of the frame.

[0009] Preferably, the sliding block forms a sliding structure by connecting the slider and the connecting plate with the limiting guide groove. When working, the sliding block slides to drive the mounting plate to fit the outer wall of the frame. By setting anti-slip grooves, it is beneficial to improve the stability of the connection between the mounting plate and the frame.

[0027] The embodiment of the present application discloses an electronic scale for monitoring vehicle safety, comprising a mounting frame 1, wherein an inner wall of the mounting frame 1 is penetrated by a mounting screw 2, an outer wall of the mounting screw 2 is threadedly connected with a connecting slider 3 which is slidably connected to the inner wall of the mounting frame 1, one end of the connecting slider 3 is screwed with a connecting plate 4, one end of the connecting plate 4 is screwed with a sliding block 5, a limited position guide groove 6 is provided at a connection portion between the mounting frame 1 and the sliding block 5, a mounting plate 7 is welded to an outer wall of the sliding block 5, a resistance strain gauge 8 is provided on the outer wall of the mounting plate 7, an anti-slip pattern 9 is provided on the outer wall edge of the mounting plate 7, a vehicle frame 10 is attached to the outer wall of the resistance strain gauge 8, and an electronic scale body 11 is fixedly connected to the outer wall of the mounting frame 1;

[0028] The adjusting component is located inside the mounting plate 7 and is used for the resistance strain gauge 8 to be fully fitted with the vehicle frame 10 .

[0029] Based on the above structure, the connecting slider 3 slides through the connecting plate 4 to drive the sliding block 5 to slide along the outer wall of the limiting guide groove 6.

By setting the anti-slip groove 9, it is beneficial to improve the stability of the connection between the mounting plate 7 and the frame 10. At the same time, the movement of the mounting plate 7 drives the resistance strain gauge 8 to fit closely with the outer wall of the frame 10, thereby realizing the fast and stable installation operation of the electronic scale body 11.

[0031] In this embodiment, two groups of connecting plates 4 are provided, and the connecting slider 3 slides to drive the two groups of connecting plates 4 to move synchronously, so as to facilitate the detection of the deformation amounts on both sides of the frame 10 .

[0032] In one embodiment, the sliding block 5 forms a sliding structure by connecting the sliding block 3 and the connecting plate 4 with the limiting guide groove 6 .

[0034] In one embodiment, the mounting plate 7 forms a clamping structure with the frame 10 through the sliding block 5 .

[0035] In this embodiment, the movement of the mounting plate 7 drives the resistance strain gauge 8 to fit closely with the outer wall of the frame 10 , thereby realizing a fast and stable installation operation of the electronic scale body 11 .

[0036] In one embodiment, the adjustment component includes:

[0037] An adjusting screw 12 is inserted through the outer wall of the mounting plate 7, an active plate 13 is threadedly connected to the outer wall of the adjusting screw 12, a connecting rod 14 is fixedly connected to the bottom end of the active plate 13 and is slidably connected to the inner wall of the mounting plate 7, and one end of the connecting rod 14 is fixedly connected to a driven plate 15 that fits the outer wall of the resistance strain gauge 8.

[0038] In this embodiment, the adjusting screw 12 rotates to drive the active plate 13 to slide through the thread, and the active plate 13 slides through the four sets of connecting rods 14 to drive the driven plate 15 to slide along the inner wall of the mounting plate 7. The sliding of the driven plate 15 drives the resistance strain gauge 8 to fully fit the outer wall of the frame 10, avoiding a gap between the resistance strain gauge 8 and the frame 10, resulting in the resistance strain gauge 8 being unable to detect the deformation of the frame 10.

[0040] In this embodiment, the active plate 13 slides through the four groups of connecting rods 14 to drive the driven plate 15 to slide along the inner wall of the mounting plate 7, thereby achieving a control operation of stable sliding of the driven plate 15.

[0042] In this embodiment, the driven plate 15 slides to drive the resistance strain gauge 8 to fully fit the outer wall of the frame 10, avoiding a gap between the resistance strain gauge 8 and the frame 10, which would cause the resistance strain gauge 8 to be unable to detect the deformation of the frame 10.

[0043] When the driving safety monitoring electronic scale of this embodiment is in use, first, the staff places the installation frame 1 on one side of the frame 10, and then the staff rotates the installation screw 2. The rotation of the installation screw 2 drives the connecting slider 3 to slide along the outer wall of the installation frame 1 through the thread. It should be noted that the inner wall of the installation frame 1 is provided with a guide groove slidably connected to the connecting slider 3.

By setting the anti-slip groove 9, it is beneficial to improve the stability of the connection between the installation plate 7 and the frame 10. At the same time, the movement of the installation plate 7 drives the resistance strain gauge 8 to fit closely with the outer wall of the frame 10, thereby realizing the fast and stable installation operation of the electronic scale body 11.

[0044] Next, the staff rotates the adjusting screw 12. The adjusting screw 12 rotates to drive the active plate 13 to slide through the thread. The active plate 13 slides through the four sets of connecting rods 14 to drive the driven plate 15 to slide along the inner wall of the mounting plate 7. The sliding of the driven plate 15 drives the resistance strain gauge 8 to fully fit the outer wall of the frame 10 to avoid a gap between the resistance strain gauge 8 and the frame 10, which makes the resistance strain gauge 8 unable to detect the deformation of the frame 10.

[0045] Finally, when the vehicle is loaded with goods, the frame 10 is deformed, causing the resistance strain gauge 8 to deform, converting the strain change on the frame 10 into resistance change, and detecting the resistance change through the electronic scale body 11 to achieve safe monitoring operation of the driving electronic scale.
