Embodiment 1

[0028] The storage battery of the supermarket shopping cart in the present invention needs to use direct current to charge. The automatic charging device of the present invention comprises generating equipment 16 and the voltage stabilizer 3 that is connected by wire, and generating equipment 16 delivers electric energy to accumulator 2 by voltage stabilizer 3, and generating equipment 16 is DC motor in the present embodiment, DC generator Set on the bottom plate of the shopping cart 1 lower end. The number of DC generators is two, which are respectively DC generator one 4 and DC generator two 5 placed on the generator base 8, and the generator base 8 can slide along the chute. The DC generator is connected with the roller 10 of the shopping cart 1 through the belt 6, and the rotation of the roller 10 provides kinetic energy for the DC generator, and the DC generator converts the kinetic energy into electric energy. The specific structure is as figure 1 , figure 2 The arra...

Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 lies in the difference of the charging device 16. The power generating device 16 in this embodiment includes a track 13 with a charging coil 14 arranged on the ground and a track 13 fixed on the bottom surface of the bottom plate 7 of the shopping cart 1. The inductance coil 12 has a specific structure such as image 3 shown. The output end of the inductance coil 12 is connected to the storage battery 2 through the voltage stabilizer 3; the charging coils 14 on the track 13 are arranged at intervals, and the track 13 and the charging coils 14 can be pre-buried in the ground and marked on the ground accordingly. The charging coil 14 is powered by the track, and the specific schematic diagram is shown in Figure 5 . In this embodiment, the charging coil 14 on the track 13 has the same shape and size as the inductive coil 12 on the shopping cart 1 . The number of turns of the charging coil 14 and the inductance coi...

Abstract

The invention relates to a supermarket shopping device, in particular to an automatic-charging supermarket shopping cart, and belongs to the field of supermarket equipment. The automatic-charging supermarket shopping cart comprises an automatic checking-out device powered by an accumulator, and further comprises an automatic charging device which can charge the accumulator in the advancing process. The automatic charging device comprises power generating equipment and a voltage regulator, wherein the power generating equipment transmits electric energy to the accumulator through the voltage regulator. According to the automatic-charging supermarket shopping cart, automatic charging of the supermarket shopping cart can be achieved, the using process is convenient and efficient, and the phenomenon of power outage in supermarket shopping does not occur. The supermarket shopping cart can be charged automatically anytime and anywhere, and due to arranging of a polar convertor, the supermarket shopping cart can conduct direct current charge for the accumulator in the advancing or retreating process.

Description

technical field [0001] The invention relates to a supermarket shopping device, in particular to a self-charging supermarket shopping cart, which belongs to the field of supermarket equipment. Background technique [0002] As people's living standards are getting higher and higher, the number of times they go to supermarkets for shopping is also increasing. Customers have higher and higher requirements for shopping experience. For this purpose, the supermarket has automatically upgraded the shopping cart. The new shopping cart includes advanced functions such as self-payment and self-navigation, and is uniformly controlled by the control system. However, the operation of the control system requires continuous power from the battery. When the battery power is exhausted, the automated shopping cart cannot be used, which not only affects the customer's shopping experience, but also affects the checkout work. Even if the staff can charge the battery in time, the battery needs ...
