Description

Technical Field

[0001] The utility model relates to the technical field of weighing instruments, in particular to a modular weighing instrument with wireless communication and power supply. Background Art

[0002] As an indispensable important tool in commercial transactions, weighing instruments / price scales play a key role in weighing goods and calculating prices. With the progress of technology and the diversification of user needs, modern weighing instruments / price scales have evolved from simple weight measurement devices to intelligent systems with multiple functions. However, with the increase in functions, the design and manufacture of weighing instruments / price scales also face a series of challenges.

[0003] First of all, most weighing instruments / price scales on the market currently use traditional wire harnesses to connect various functional modules (such as sensors, displays, processors, etc.). With the increasing richness of device functions, this wiring method results in intricate internal wiring of the whole machine, which not only increases the assembly difficulty but also may cause signal interference, reducing the reliability and stability of the product.

[0004] Secondly, since the functional modules are usually connected by wire harnesses, it is difficult to disassemble the modules, making it difficult to achieve quick and convenient replacement or upgrade, which is an obvious limitation for application scenarios that require frequent maintenance or configuration adjustment according to business needs.

[0005] In addition, in order to protect the internal wire harness from damage, existing weighing instruments / price scales usually need to be equipped with additional structural parts to fix and protect the wire harness. These structural parts not only increase the overall volume of the device but also raise the production cost, and at the same time bring inconvenience to packaging and transportation. In addition, the larger volume also occupies more sales space, limiting the market competitiveness of the product.

[0006] In particular, the space reserved for the wire harness by the structural parts often becomes a potential safety hazard. For example, small organisms such as mosquitoes and cockroaches can easily invade the interior of the device through these structural gaps. They may bite or damage the internal main board and wires, which may lead to equipment failure or short circuit, and even cause more serious safety accidents such as fires.

[0007] The above problems not only limit the functional expansion and technological progress of weighing instruments but also have a certain negative impact on the user experience.

[0008] In view of this, the inventor has specifically designed a modular weighing instrument with wireless communication and power supply, and this case is thus generated. Summary of the Utility Model

[0009] In order to solve the above problems, the technical solution of the utility model is as follows:

[0015] A function module, detachably connected to the module connection positions and independently partitioned from the installation space, including a second antenna, a slave station of a radio frequency chip, a function main board, and function components;

[0016] A power reception component, electrically connected to the function module, including a second induction coil, a wireless power reception controller, and a voltage conversion module, for receiving the magnetic field generated by the first induction coil and converting it into electric energy to supply power for the normal operation of the function main board and function components;

[0017] Wherein, the function module establishes a data interaction channel through the first antenna, the second antenna, the master station of the radio frequency chip, and the slave station of the radio frequency chip.

[0044] Among them, the functional module 50 establishes a data interaction channel through the first antenna, the second antenna 51, the wireless radio frequency chip master station, and the wireless radio frequency chip slave station 52.

[0045] First, the detachable manner between the functional module 50 and the module connection bit 12 is snap connection or slide rail connection. As Figure 3 shown, in this embodiment, the functional module 50 is snap-connected to the outer side wall of the weighing instrument main body 10, that is, a snap hole position 13 is opened on the outer side wall surface of the weighing instrument main body 10, and a snap portion 55 is correspondingly provided on the contact surface between the functional module 50 and the weighing instrument main body 10. After the snap portion 55 of the functional module 50 is pushed into the snap hole position 13, the functional module 50 realizes a fixed connection with the weighing instrument main body 10. At this time, the snap hole position 13 is also covered by the functional module 50, maintaining the relative independence of the outer side wall surface of the weighing instrument main body 10, and a gap is formed on the wall surface to prevent dust particles or insects from drilling in.

[0059] 3. There is no need to consider wiring between each module and the main body, so it can be sealed to meet the requirements of insect prevention and waterproofing, making the product more adaptable to the harsh market use environment.

[0060] 4. The modular functions can facilitate R & D, provide a variety of modular functions, increase product diversity, and reduce the development cost of the existing weighing instruments due to the major changes in the whole machine mold caused by function changes.

This modular design optimizes the production process of the whole machine, transforms it into modular production, significantly reduces the transportation volume, and thus greatly saves the packaging cost. After each functional module is modularized, it is convenient for quick replacement and upgrade, providing great convenience for after-sales service and product iteration and upgrade at the client side. In addition, each module is connected, communicated and powered wirelessly with the main body, without considering the wiring problem, so a sealed design can be realized to meet the requirements of insect prevention and waterproofing, enabling the product to better adapt to the harsh use environment and improving the overall durability and reliability. The modular function design provides more convenience for the R & D team, can quickly integrate a variety of functional modules, increase product diversity, and at the same time reduce the development cost of the whole machine mold caused by function changes, accelerating the speed of new products being launched into the market. These beneficial effects not only improve the production efficiency and maintenance convenience of the weighing instrument / price scale, but also enhance the market adaptability and cost-effectiveness of the product, bringing significant benefits to manufacturers and users.
