Abstract
Description
Technical Field
[0001] The present application relates to the field of battery charging, and more particularly, to a multi-layer charging box. Background Art
[0002] In certain existing technologies, it is necessary to complete large-scale charging of multiple batteries simultaneously. Currently, for centralized charging of nickel-chromium batteries, although simultaneous charging can be achieved, there are still certain defects. For example, the current charging method is in series. When some charging modules malfunction, it affects the charging of all charging batteries. In addition, the connection method of the current charging box results in a large occupied space area when charging multiple batteries simultaneously.
[0003] Therefore, those skilled in the art need to improve the existing charging box to overcome the above defects. Summary of the Utility Model
[0004] The main purpose of the present application is to provide a multi-layer charging box, which changes the original series charging to parallel charging. When a certain charging module malfunctions, it does not affect the overall use, and a three-layer drawer structure is adopted, greatly reducing the occupied space.
[0005] To achieve the above object, in a first aspect, the present application provides a multi-layer charging box, including a charging box housing, at least two layers of charging plates slidably arranged with the charging box housing, and a charging bottom plate fixedly arranged in the charging box housing. A plurality of charging interfaces and power connection ports are arranged on the charging bottom plate. The charging interfaces are respectively connected to the corresponding charging plates, and the power connection ports are connected to a CRPS power supply. A number of battery bases for installing charging batteries are arranged in parallel on each layer of the charging plate, and each group of battery bases has an even number of battery installation cavities.
[0006] Further improved, there are two power connection ports, and both of the two power connection ports are connected to a CRPS power supply.
[0007] Further improved, at least two layers of drawer plates are slidably arranged in the charging box housing, the charging plates are fixedly arranged on the corresponding layer of drawer plates, and a guiding structure is arranged between each layer of drawer plate and the charging box housing.
[0008] Further improved, the guiding structure includes a guide rail arranged on the charging box housing and a guide rail groove arranged on the back of the drawer plate and cooperating with the guide rail.
[0009] Further improved, a drag chain is also arranged between each layer of drawer plate and the charging box housing.
[0010] Further improved, the CRPS power supply is a 12V redundant power supply.
[0011] Further improved, functional accessories are also provided inside the charging box housing.
[0012] Further improved, the functional accessories include a cooling fan and an LED indicator light.
[0013] Further improved, mesh plates are fixedly provided on both sides of the charging box housing.
[0014] Compared with the prior art, the multi-layer charging box provided by the present utility model has the following beneficial effects: 1. The CRPS power supply is used, making the entire charging system stable. If one fails, the other can be put into use, and the load balance is ensured, that is, each charging battery is charged at the same voltage and current; 2. The charging is carried out in a parallel manner, thus avoiding the charging of other bases being affected by a failure of a certain battery base; 3. The drawer-type three-layer structure is adopted, greatly reducing the occupied floor area, reducing the volume of the charging box body, and being convenient for carrying and transportation.

[0027] Such as Figure 1 Figure 4As shown in the figure, a multi-layer charging box includes a charging box housing 1, at least two layers of charging plates 2 slidably arranged with the charging box housing 1, and a charging bottom plate 3 fixedly arranged in the charging box housing 1. A plurality of charging interfaces 4 and a power connection port 5 are arranged on the charging bottom plate 3. The charging interfaces 4 are respectively connected to the corresponding charging plates 2, and the power connection port 5 is connected to a CRPS power supply 6. A number of battery bases 7 for installing charging batteries are arranged in parallel on each layer of the charging plate 2, and each group of the battery bases 7 has an even number of battery installation cavities.
[0028] In this embodiment, a three-layer drawer structure is adopted. That is, three charging interfaces 4 are arranged on the charging bottom plate 3 and are respectively connected to the upper, middle, and lower three layers of drawer-type charging plates 2. And its two power connection ports are connected to the CRPS power supply 6, that is, two 12V redundant power supplies are connected. Using its characteristics, when one power supply fails, the other immediately comes into use and alarms through the buzzer on the main board, thus realizing the stability of the entire system. In addition, through the above settings, it is also beneficial to the balance of load charging, so that each battery can be charged under the same voltage and current. That is, the power connection port 5 has two, and both of the two power connection ports 5 are connected to the CRPS power supply 6, and the CRPS power supply 6 is a 12V redundant power supply.
[0029] Preferably in this embodiment, at least two layers of drawer plates 8 are slidably arranged in the charging box housing 1, the charging plates 2 are fixedly arranged on the corresponding layers of the drawer plates 8, and a guiding structure is arranged between each layer of the drawer plates 8 and the charging box housing 1. The guiding structure includes a guide rail arranged on the charging box housing 1 and a guide rail groove arranged on the back of the drawer plate 8 and cooperating with the guide rail.
[0030] Thus, when the battery needs to be charged, the drawer plate 8 is directly pulled out, and the batteries are sequentially placed on the battery bases 7 and then charged. After charging is completed, the drawer plate 8 is directly pulled out and the batteries are taken out one by one, which is convenient to operate.
[0031] Preferably, a cable carrier is also arranged between each layer of the drawer plates 8 and the charging box housing 1.
[0032] Preferably, functional accessories are also arranged in the charging box housing 1. The functional accessories include a cooling fan and an LED indicator light. Since a number of batteries are charged under the same voltage and current, especially in a parallel connection mode, the current in the system is relatively large. Therefore, in order to improve the heat dissipation effect, a cooling fan is arranged for heat dissipation. In addition, in order to facilitate the operator to understand the charging situation, an LED indicator light is also arranged, which at least indicates two colors during charging and after charging is completed.
[0033] Preferably, net plates 9 are fixedly arranged on both sides of the charging box housing 1.
[0034] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
