Description

Technical Field

[0001] The utility model relates to an electronic scale, in particular to a display box of the electronic scale. Background Art

[0002] Usually, the display screen of an electronic scale is arranged at the same level as the scale body. This conventional structure of an electronic scale can easily cause the display screen to be blocked by the weighing object when weighing larger objects, making it inconvenient to read the weighing data. When the electronic scale needs to be placed on the ground or at a lower position for weighing, the user is required to bend over or squat to see the weighing data clearly, which makes the electronic scale inconvenient to use. In addition, the display screen and the scale body are arranged at the same level, which means that the user can only read the weighing data next to the electronic scale, making it inconvenient to show the weighing value to others in real time.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0025] Reference Figures 1 to 7 An external display box of an electronic scale includes a shell and a circuit board installed in the shell, and a display screen 3 and a button located in the shell and electrically connected to the circuit board. A user can use the control button to adjust the weighing unit, such as converting the weighing unit from kilograms to catties. The user can directly read the data without converting the unit, which is convenient to use. The circuit board is provided with a wireless communication module for wireless communication with the electronic scale. The wireless communication module mentioned in this embodiment adopts a wireless communication circuit structure as recorded in the patent document with publication number CN1471272A, which is a disclosed prior art solution; correspondingly, a corresponding wireless communication module is also required to be arranged in the scale body of the electronic scale so that the two can perform signal communication. The shell includes a face cover 1 and a bottom box 2, and a accommodating cavity is formed between the face cover 1 and the bottom box 2. A window portion 11 is provided through the front end of the face cover 1, and the display screen 3 is placed behind the window portion 11. A recessed portion 21 is provided inwardly on the back plate of the bottom box 2, and a bracket 4 hinged to the bottom box 2 is installed in the recessed portion 21; the bottom box 2 is also provided with an inwardly concave hanging hole portion 22. The display box of the present embodiment is independently arranged. This separate design from the scale body allows the display box to be arbitrarily placed at other positions where data is easy to read when the electronic scale is weighing an object, without being blocked by the weighing object, making it convenient for users to read the weighing data. Moreover, the display box is compact and can be held in the hand to show the weighing data to others. At the same time, a bracket is arranged on the back of the bottom box of the display box, which can support the display box on the desktop for display, making it more convenient to read the data using the electronic scale display box, thereby improving the user experience. At the same time, a hanging hole is arranged on the bottom box, and users can place the electronic scale display box on a platform or hang the electronic scale display box on a wall through the bracket according to their own needs. A variety of fixing methods can adapt to more diversified usage scenarios.

[0026] The top of the recessed portion 21 is provided with a groove 211, and a raised stopper 212 is provided at the top of the groove 211; the inner wall at the lower end of the groove 211 is provided with a curved surface. The stopper is provided on the recessed portion to fix the bracket at a certain angle, preventing the bracket from folding excessively and causing the electronic scale display box to fall over.

[0027] The top of the bracket 4 is set in an arc shape, and a convex edge 41 is also set at the top of the bracket 4. After assembly, the bracket 4 is unfolded, and the convex edge 41 abuts against the limit block 212. The bottom of the bracket 4 is also provided with a concave portion 42. The inner side of the bracket 4 is provided with a hinge shaft, and the hinge shaft passes through the hinge shaft hole provided on the bottom box 2 to hinge the bracket 4 with the bottom box 2. After the bracket 4 is unfolded so that the convex edge 41 abuts against the limit block 212, the angle between the bracket 4 and the bottom box 2 is 90 。 Since the bracket is mounted on the recessed portion of the bottom box, when the bracket is folded, the bracket is flush with the outer surface of the bottom box, which is inconvenient for the user to fold the bracket. Therefore, a recessed portion is provided at the bottom end of the bracket to facilitate the user to fold the bracket out of the bottom box.

[0028] A fixing plate is installed on the back of the display screen 3 , the fixing plate is provided with screw holes, the surface cover 1 is provided with fixing holes, and bolts pass through the screw holes and the fixing holes to fix the display screen 3 on the surface cover 1 .

[0029] The accommodating cavity is also provided with a sounding device, and the bottom box 2 is provided with a sound outlet 23 at a position corresponding to the sounding device. In this embodiment, a sounding device is provided in the accommodating cavity, and when weighing an object, the sounding device can also broadcast the weighing data, so that the user can understand the weighing data even when it is inconvenient to check the display box.

[0030] The bottom box 2 is provided with a concave battery compartment 24 , in which the battery is installed to form an electrical connection with the circuit board, and a battery rear cover 25 is installed at the rear end of the battery compartment 24 to close the battery compartment 24 .

[0031] The front end of the cover 1 is also provided with a panel 5, and the panel 5 is made of a transparent material in the area corresponding to the display screen 3. In this embodiment, the panel is made of a light-transmitting material such as tempered glass.
