Description

Technical Field

[0001] The utility model relates to the technical field of automobile scale limiter, in particular to an automobile scale limiter component. Background Art

[0002] A truck scale is a device used to measure the weight of large vehicles and their cargo. When the vehicle drives onto the weighing platform of the truck scale, the gravity sensor at its bottom will be compressed and produce elastic deformation, and the deformation will be converted into an electrical signal output, which will be displayed on the digital display device as the total weight of the vehicle. The truck scale weighs the vehicle to ensure that the vehicle is not overloaded within its load range, thereby ensuring the safety of roads and bridges and reducing the incidence of traffic accidents.

[0003] Since there is a certain buffer gap between the weighing platform and its base, the weighing platform will shake due to gravity when the car drives onto the weighing platform, causing the weighing platform to hit the base and affecting the service life of the car scale. The shaking will cause the pressure received by the gravity sensor to be unstable, resulting in inaccurate weighing results.

[0004] In order to solve the above problems, we have made improvements and proposed a truck scale limit assembly. Utility Model Content

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1-4 As shown, a vehicle scale limit assembly includes a basic component 1, a reserved groove 3 is opened on the upper surface of the basic component 1, a weighing platform 2 is slidably installed on the inner surface of the reserved groove 3, a buffer gasket 5 and a spring rod 7 are installed on the side surface of the weighing platform 2, a first gear 11 is installed on the lower surface of the weighing platform 2, a mounting groove 16 is opened on the inner surface of the reserved groove 3, and a second gear 13 is rotatably installed inside the mounting groove 16.

[0022] Inclined loading ramps are fixedly installed on both sides of the base component 1 to facilitate vehicles getting on and off the truck scale, reduce the pressure on the edge of the truck scale when the vehicle goes on and off, and improve the service life of the truck scale. A slide groove 8 is opened on the inner surface of the reserved groove 3, and a slider 10 is slidably installed inside the slide groove 8. The outer surface of the slider 10 is fixedly connected to the spring rod 7.

[0023] A reinforcing rib 9 is fixedly connected between the lower surface of the spring rod 7 and the outer surface of the slider 10 , the end of the spring rod 7 is fixedly connected to the rear surface of the buffer gasket 5 , and the front surface of the buffer gasket 5 is fixedly connected to the side surface of the weighing platform 2 .

[0024] When the weighing platform 2 moves up and down under the action of gravity, it drives the spring rod 7 and the slider 10 to slide up and down along the slide groove 8 to adjust the position. The reinforcing rib 9 improves the stability of the connection between the lower part of the spring rod 7 and the slider 10, and the support of the spring rod 7 to the lateral force.

[0025] A plurality of gravity sensors 4 are fixedly installed on the inner bottom surface of the reserved groove 3, and an elastic body is installed on the top of the gravity sensor 4. The top of the gravity sensor 4 is fixedly connected to the lower surface of the weighing platform 2. When the car drives onto the weighing platform 2, the weighing platform 2 and the gravity sensor 4 are pressed down, and the gravity sensor 4 converts the pressure received into an electrical signal and transmits it to an external digital display mechanism. A gap is left at the edge of the weighing platform 2 and the edge of the reserved groove 3 to prevent the weighing platform 2 from colliding with the edge of the reserved groove 3 and causing damage when shaking.

[0026] The cylinder 6 is fixedly installed at the bottom of the mounting groove 16, the lower surface of the second gear 13 is rotatably connected to the top of the cylinder 6, the upper surface of the second gear 13 is provided with an annular circular groove 14, the upper surface of the second gear 13 is fixedly installed with a torsion spring 15, and the top of the torsion spring 15 is fixedly connected to the inner top surface of the mounting groove 16.

[0027] A fixing rod 12 is fixedly mounted on the lower surface of the weighing platform 2 , and the other end of the fixing rod 12 is slidably connected to the inner surface of the circular groove 14 , and the first gear 11 is meshed with the second gear 13 .

[0028] When the weighing platform 2 shakes, the first gear 11 and the second gear 13 are driven to rotate, so that the bottom of the torsion spring 15 rotates a certain angle. The torsion spring 15 twists back and forth during the shaking of the weighing platform 2 to generate a pulling force, thereby reducing the amplitude of the shaking and the number of shaking times.

[0029] A sensor is installed inside the spring rod 7, and a controller electrically connected to the sensor is installed inside the cylinder 6.

[0030] Working principle: When the vehicle is in use, the vehicle drives to the center of the weighing platform 2. At this time, the weighing platform 2 will shake back and forth due to gravity and the thrust of the vehicle. When the weighing platform 2 moves up and down due to gravity, it drives the spring rod 7 and the slider 10 to slide up and down along the slide groove 8 to adjust the position. The reinforcing rib 9 improves the stability of the connection between the lower part of the spring rod 7 and the slider 10, and the support of the spring rod 7 to the lateral force. When the car drives onto the weighing platform 2, the weighing platform 2 and the gravity sensor 4 are pressed down. The gravity sensor 4 converts the pressure received into an electrical signal and transmits it to the external digital display mechanism. There is a gap between the edge of the weighing platform 2 and the edge of the reserved groove 3 to prevent the weighing platform 2 from colliding with the edge of the reserved groove 3 when shaking and causing damage. When the weighing platform 2 shakes, it drives the first gear 11 and the second gear 13 to rotate, so that the bottom of the torsion spring 15 rotates a certain angle. The torsion spring 15 twists back and forth during the shaking process of the weighing platform 2 to generate a pulling force, reduce the amplitude of the shaking and reduce the number of shaking, and improve the accuracy of gravity measurement.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
