[0031] Please refer to Figures 1 to 5 The utility model provides a digital electronic ground scale, comprising:

[0032] A weighing platform 10, the bearing surface of the weighing platform 10 is provided with a bearing plate 101; and

[0033] The weighing module 20 includes a digital weighing sensor 201, a signal processor 202 and a weight display 203.

[0034] In the technical solution of the present utility model, the digital electronic floor scale adopts a digital sensor, and the digital sensor and the signal processor 202 are arranged inside the weighing platform 10, and the weight display 203 is arranged outside the weighing platform 10. When the vehicle arrives on the load-bearing plate 101, the digital sensor generates a corresponding weight signal, and the weight signal is transmitted to the signal processor 202 through a cable. The signal processor 202 processes and transforms the weight signal and transmits it to the weight display 203 through a cable, and the corresponding vehicle weight information is displayed on the weight display 203. The digital electronic floor scale proposed in the utility model improves the anti-interference ability of the output information by adopting the digital weighing sensor 201 and the signal processor 202, thereby avoiding measurement errors.

[0035] In this embodiment, the digital electronic floor scale includes a weighing platform 10 and a weighing module 20. The weighing platform 10 is a frame structure. The weighing platform 10 forms a plurality of hollow areas for installation of the weighing module 20 and other functional modules such as a limit device 30. The hollow areas are also convenient for transportation, shipment, clamping and fixing. At the same time, the frame structure of the weighing platform 10 can also reduce material costs and reduce the weight of the weighing platform, thereby reducing the transportation burden. A plurality of bearing plates 101 are laid on the bearing surface of the weighing platform 10. By setting the bearing plates 101, the hollow areas can be covered so that the load-bearing vehicle can drive to the stable weighing platform 10 for load-bearing. The digital weighing sensor 201 and the signal processor 202 are fixed in the hollow area by a bolt structure. The weight display 203 is provided. On the outside of the weighing platform, the distance between the weight display 203 and the outside can be determined according to the actual layout of the site, and the digital weighing sensor 201, the signal processor 202 and the weight display 203 are connected by a cable 205. When the vehicle reaches the weighing platform 10, the digital weighing sensor 201 detects the weight change through the strain gauge to generate an electrical weight signal. The weight signal is transmitted to the signal processor 202 through the cable 205. The signal processor 202 processes the weight signal and then transmits it to the weight display 203 to display the vehicle load-bearing information. By using the digital weighing sensor 201, the measurement error caused by the environment during the weighing process of the ground scale can be reduced, thereby improving the measurement accuracy.

Each digital weighing sensor 201 is electrically connected to the signal processor 202 through a set of cables 205. When the vehicle reaches the load-bearing surface, each digital weighing sensor 201 performs weight detection, and multiple groups of weight signals are transmitted to the signal processor 202 for processing. By arranging a digital weighing sensor 201 at the four corners of the weighing platform, the measurement results can be further improved to ensure the accuracy of the data.

[0038] In one embodiment of the present invention, Figure 1 As shown, a first hollow portion 10a is provided at each of the four corners of the weighing platform 10, and the first hollow portion 10a is arranged to penetrate along the thickness extension direction of the weighing platform 10; a mounting plate 102 is welded to each first hollow portion 10a, and a digital weighing sensor 201 is arranged on the side of the mounting plate 102 facing away from the bearing surface of the weighing platform 10 by bolts.

It can be understood that in order to facilitate the use of the weighing platform in multiple load-bearing sites, the weighing platform is not completely fixed on the ground. At this time, the symmetrical platform is stopped and limited by the limit part 302. When the vehicle travels to the load-bearing surface, when the weighing platform moves due to the inertia of the vehicle itself, the inner side wall of the second hollow part 10b will abut against the limit part 302 to avoid large shaking.

[0045] In one embodiment of the present invention, Figure 5 As shown, the limiting portion 302 includes a first limiting section 3021 and a second limiting section 3022, which are an integral structure; the first limiting section 3021 and the second limiting section 3022 can respectively abut against any two adjacent inner side walls of the second hollow portion 10b.

[0047] In one embodiment of the present invention, Figure 2 , Figure 4 as well as Figure 5 As shown, the limiting device 30 also includes a limiting ring 303, which is arranged on the side of the fixing part 301 facing the weighing platform 10; the digital weighing sensor 201 is provided with a supporting leg 204 on the side facing away from the weighing platform 10, and the supporting leg 204 is movably inserted in the limiting ring 303.

[0048] In this embodiment, the limit device 30 also includes a limit ring 303, which is arranged on the side of the fixed part 301 facing the weighing platform 10, so that the limit ring 303 and the limit part 302 are arranged on the same plane on the fixed part 301, and a support leg 204 is provided on the side of the digital weighing sensor 201 facing away from the weighing platform 10, and the support leg 204 is movably inserted in the limit ring 303 to prevent the weighing platform from forming a fixed connection with the limit device 30 through the digital load-bearing sensor, thereby not affecting the measurement result of the digital load-bearing sensor.

[0049] In one embodiment of the present invention, Figure 4 As shown, the support leg 204 includes a first support segment 2041 and a second support segment 2042. The first support segment 2041 is connected to the digital weighing sensor 201, and the second support segment 2042 is movably inserted in the limiting ring 303; the cross-sectional area of ​​the second support segment 2042 gradually increases from one end connected to the first support segment 2041 to the end away from the first support segment 2041.

The cross-sectional area of ​​the second support segment 2042 gradually increases from one end connected to the first support segment 2041 to the end away from the first support segment 2041, so as to increase the contact area with the fixed plate. At the same time, the bottom end of the second support segment 2042 forms a narrow fitting gap with the inner circumferential wall of the limiting ring 303, which facilitates the insertion of the second support segment 2042 into the limiting ring 303 on the one hand, and limits the activity space of the second support segment 2042 at the same time.
