[0023] It should be noted that in the description of the embodiments of this application, the terms "front," "rear," "left," "right," "up," "down," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0024] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1 to 4This application provides a portable electronic scale, including a housing 1. The housing 1 is made of ABS plastic, specifically ABS-757K. This material has good rigidity, toughness, and impact resistance, ensuring the structural strength of the housing 1, while also being lightweight, which improves the portability of the electronic scale. A middle block 3 is fixed to the back of the housing 1 with screws. The middle block 3 is made of PVC, specifically PVC-SG5, which has good chemical stability and a certain mechanical strength, and is also low in cost.

[0026] Folding components 2 are provided on both sides of the outer shell 1 and the middle block 3. The folding components 2 include a weighing plate 21, which is made of aluminum alloy, model 6061. This material has low density and high strength, which can reduce the overall weight while ensuring the load-bearing capacity of the weighing plate 21. An adjusting block 23 is fixedly installed at the bottom of the weighing plate 21 by welding. The adjusting block 23 is made of stainless steel, model 304, which has good corrosion resistance and wear resistance, extending the service life of the adjusting block 23.

[0027] Side plates 24, also made of stainless steel (model 304), are fixed to both sides of the middle block 3 with screws. The side plates 24 are arranged in pairs, with adjusting blocks 23 positioned between their corresponding sides. The adjusting blocks 23 and side plates 24 are rotatably connected by bolts 25, which are M4×10 stainless steel bolts. Tightening or loosening the bolts 25 changes the tightness of the side plates 24, thereby adjusting the fixing state and rotational damping of the adjusting blocks 23 and side plates 24. When the bolts 25 are tightened, the friction between the adjusting blocks 23 and side plates 24 increases, fixing the weighing plate 21 in a specific position. When the bolts 25 are loosened, the adjusting blocks 23 can rotate flexibly around the bolts 25, facilitating folding operations.

[0028] A protective pad 22 is glued to the top of the weighing plate 21. The protective pad 22 is made of silicone material, model HT-801. This silicone material has good elasticity and wear resistance, which can effectively protect the items and the weighing plate 21, while increasing the friction between the items and the weighing plate 21 to prevent the items from sliding during the weighing process. The top of the weighing plate 21 is flush with the top of the outer shell 1 and the top of the middle block 3 to ensure the stability of the items when placed.

[0029] Pressure sensors 6 are fixedly installed on the front and rear sides of the bottom of the weighing plate 21, the bottom of the outer casing 1, and the bottom of the middle block 3 using screws. The pressure sensors 6 are strain gauge pressure sensors of model FSS1500N. This sensor has high measurement accuracy, a range of 0-150kg, which can meet daily weighing needs, and is compact in size and easy to install. The bottoms of each pressure sensor 6 are flush with each other to ensure that each sensor is evenly stressed during weighing, thus improving weighing accuracy.

[0030] The charging port 5 is fixedly installed on the front of the outer casing 1 by a clip. The charging port 5 uses a Micro-USB interface, model MIC-5P. This interface is highly universal and allows users to charge the electronic scale with common chargers. The display screen 4 is embedded and fixedly installed on the top inner side of the outer casing 1. The display screen 4 uses an LCD screen of model 12864. This display screen has a clear display, low power consumption, can clearly display the weighing results, and is small in size, making it suitable for installation inside the outer casing 1.

[0031] A rubber protective sleeve 26 is glued and fixed between the middle block 3 and the weighing plate 21. The rubber protective sleeve 26 is made of natural rubber, model NR-10, which has good elasticity and flexibility, and has a certain redundant length. It can freely extend and retract during the folding and unfolding of the weighing plate 21, and at the same time can prevent dust, moisture and other substances from entering the electronic scale and protect the internal components.

[0032] The main control circuit board and rechargeable battery are fixedly mounted inside the outer casing 1 with screws. The main control circuit board is an STM32F103C8T6 microcontroller development board. This microcontroller is stable, fast, and can quickly receive and process the weighing signal transmitted by the pressure sensor 6, and control the display screen 4 to display the weighing result. The rechargeable battery is an 18650 lithium battery with a capacity of 2000mAh and a voltage of 3.7V, which can provide a stable power supply for the entire electronic scale and has a long battery life.

[0033] The main control circuit board is electrically connected to the rechargeable battery, display screen 4, and charging port 5 via wires. The rechargeable battery provides power to the entire electronic scale, and the charging port 5 can be charged by an external power source. A wire made of AWG28 copper core is threaded inside the rubber protective sleeve 26. This wire has a small diameter, good flexibility, and is easy to thread inside the rubber protective sleeve 26. One end of the wire is electrically connected to the pressure sensor 6 at the bottom of the weighing plate 21, and the other end is electrically connected to the main control circuit board inside the outer casing 1, transmitting the weighing signal detected by the pressure sensor 6 to the main control circuit board.

[0034] Working Principle: When using this portable electronic scale, firstly, the weighing plate 21 is rotated and unfolded around bolt 25. Then, the tightness of bolt 25 is adjusted to fix the weighing plate 21, making its top flush with the tops of the outer casing 1 and the intermediate block 3. Next, the item to be weighed is placed on the scale. The weight of the item is transmitted through the weighing plate 21, outer casing 1, and intermediate block 3 to the pressure sensors 6. The pressure sensors 6 convert the detected pressure signals into electrical signals, which are transmitted to the main control circuit board via wires. The main control circuit board processes and calculates the electrical signals to obtain the weight value of the item and transmits the weight value to the display screen 4, which displays the weighing result. When the scale's battery is low, it can be charged via the charging port 5 by connecting to an external power source. When carrying or storing the scale, bolt 25 is loosened, and the weighing plate 21 is rotated and folded around bolt 25, reducing the overall size of the scale for easy carrying and storage.
