DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment

[0021] Please refer to Figures 1 to 4 , which is an embodiment of the present utility model. This embodiment provides a technical solution: an automatic reset force transmission structure for an electronic truck scale, including a base 100, a weighing body 200, and a force transmission structure 300 disposed therebetween. The force transmission structure 300 includes an inner cavity 301, an electronic pressure sensor 302, a fixed pile 303, a fixed rod 304, a movable slot 305, and a spring 306. The inner cavity 301 is opened on the top surface of the base 100, and the electronic pressure sensor 302 is fixed inside the inner cavity 301. The number of the electronic pressure sensors 302 is four. The fixed pile 303 is fixed on the bottom surface of the weighing body 200 and is located directly above the electronic pressure sensor 302. The number of the fixed piles 303 is also four and corresponds to the electronic pressure sensors 302 one by one. After the vehicle drives onto the weighing body 200, the weighing body 200 drives the fixed pile 303 to press down, thereby squeezing the corresponding electronic pressure sensor 302 for measurement. The fixed rods 304 are fixed on the bottom surfaces of the four corners of the weighing body 200 and are slidably inserted into the movable slots 305 opened on the surface of the base 100, so that the weighing body 200 can only move vertically up and down along the fixed rods 304 to ensure stable lifting. The spring 306 is sleeved on the surface of the fixed rod 304 and abuts against the bottom surface of the weighing body 200 and the top surface of the base 100. When the weighing body 200 presses down, the spring 306 will be compressed. When the vehicle drives away, the weighing body 200 will automatically reset under the elastic force of the spring 306. The distance between the fixed pile 303 and the electronic pressure sensor 302 is small, so the compression amplitude of the spring 306 is very small. The elastic force of the spring 306 can be ignored compared with the self-weight of the vehicle and does not affect the measurement accuracy.

[0022] In this embodiment, preferably, the force transmission structure 300 also includes a bottom groove 307, which is opened at the bottom of the movable slot 305, and the bottom end of the fixed rod 304 extends into the bottom groove 307. The force transmission structure 300 also includes a strip groove 308 and a bolt 309. The strip groove 308 is opened on the outside of the bottom groove 307, and the bolt 309 is movably installed in the strip groove 308, and the inner end is threadedly connected to the bottom end of the fixed rod 304. The spacing between the strip grooves 308 is greater than the bolt 309, which will not affect its lifting and lowering movement. The design of the bolt 309 can prevent the fixed rod 304 from falling off from the movable slot 305, and personnel can also remove the bolt 309, thereby disassembling the fixed rod 304 together with the scale body 200, so as to maintain the internal electronic pressure sensor 302 and the like.

[0023] In this embodiment, preferably, a shielding assembly 400 is provided on the bottom surface of the scale body 200 to play a shielding role and prevent water or dust from entering the interior of the inner cavity 301. The shielding assembly 400 includes a shielding cover 401, which is fixed to the bottom of the scale body 200, and its bottom end extends into the interior of the inner cavity 301. The outer wall of the shielding cover 401 is slidably fitted with the inner wall of the inner cavity 301, and can be movably covered on the outside of the inner cavity 301.

[0024] In this embodiment, preferably, the shielding assembly 400 also includes a side 402, a plastic rod 403 and a slot 404. The side 402 is fixed to the outer edge of the shield 401, and the plastic rod 403 is fixed to the bottom surface of the scale body 200 and is plugged into the slot 404 opened on the side 402. The bottom end of the plastic rod 403 is a spherical structure, and the bottom end of the plastic rod 403 is snap-fitted into the lower port of the slot 404, thereby completing the detachable fixed installation of the shield 401.

[0025] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
