Description

Technical Field

[0001] This utility model belongs to the field of portable power supply products, and specifically relates to a charging box that can display the power level and charge at the same end. Background Technology

[0002] For reusable dry cell batteries such as lithium-ion, nickel-metal hydride, and nickel-cadmium batteries, a charging case is usually required to charge them.

[0003] Currently, battery cases designed to charge dry cell batteries typically only support 220V household power and cannot charge other electronic devices, resulting in a limitation in their single usage mode.

[0004] To address this issue, patent application number 201821612469.0 discloses a portable charging and power supply device with detachable standard batteries. It includes a casing, a PCB board, positive and negative electrode plates connected to the PCB board, and a discharge and charging interface on the PCB board. The casing can hold cylindrical or square standard lithium batteries, which can be removed for use. The charging case can both charge standard lithium batteries via the charging interface and charge external electronic devices using standard lithium batteries via the discharge interface, increasing the usability of the charging case and expanding its application scenarios.

[0005] However, in the charging box disclosed in the above patent, the positive and negative terminals for charging are located at both ends of the charging compartment. During charging, in order to ensure that the battery is tightly connected to the positive and negative terminals of the PCB board, both ends of the battery need to be pressed tightly inside the charging compartment. At the same time, when the positive and negative terminals are located at the two ends respectively, charging lines need to be equipped at both ends of the charging compartment, which makes the product structure more complex and the production more troublesome. Utility Model Content

[0006] To solve the above problems, the primary objective of this utility model is to provide a charging box that can display the battery level and the charging status at the same end, so that users can easily observe the battery level.

[0007] Another objective of this utility model is to provide a charging box that can display the battery level and charge at the same end. The positive and negative terminals for charging are located at the same end of the charging compartment. During charging, there is no need to press the two ends of the battery together, making charging more convenient.

[0008] Another objective of this invention is to provide a charging box that can display battery level and simultaneous charging, eliminating the need for charging lines at both ends of the charging compartment, thus simplifying the product structure and manufacturing process.

[0009] To achieve the above objectives, the technical solution of this utility model is as follows:

[0010] This utility model provides a charging box that can display battery level and charging at the same end, including: a box body, a control board, and a charging positive terminal and a charging negative terminal connected to the control board. The box body is provided with a charging compartment for placing batteries, and the charging positive terminal and the charging negative terminal are located at the same end of the charging compartment. A display screen is also installed on the outer side of the box body, and the display screen is electrically connected to the control board.

[0011] Furthermore, the upper end of the charging compartment is provided with an opening for placing and removing the battery, and the positive and negative charging terminals are located at the lower end of the charging compartment. Users can place the battery into the charging compartment or remove it from the charging compartment through the opening. When placing the battery, the positive and negative terminals at the lower end of the battery connect to the positive and negative charging terminals of the charging compartment, respectively. As long as the lower end is tightly fitted to the charging compartment, normal charging is guaranteed, making charging more convenient.

[0012] Furthermore, the control board is provided with a first conductive post, the bottom of which is electrically connected to the control board, and the upper end of which forms the charging negative electrode; a through hole is opened in the middle of the first conductive post, and a second conductive post separate from the first conductive post is provided in the hole, the lower end of which is electrically connected to the control board, and the upper end of which forms the charging positive electrode.

[0013] Furthermore, the first conductive post is a ring-shaped column, and the second conductive post is a conductive pin. The conductive pin is disposed inside the ring structure of the column and is separate from the column. This not only ensures the stability of the charging structure but also saves the space occupied by the conductive pin, which helps to reduce the size of the product and facilitates its portable use.

[0014] Furthermore, the control board is also connected to a bidirectional charging interface, which extends through and is exposed within the housing. In this application, the charging box can both charge a standard battery via the bidirectional charging interface and charge external electronic devices using the standard battery via the bidirectional charging interface, thus enabling the charging box to simultaneously perform battery charging and power supply functions for external electronic devices. This increases the usability of the charging box and expands its application scenarios.

[0015] Furthermore, a wireless charging coil is also installed on the box body. The wireless charging coil is electrically connected to the control board and can wirelessly charge electronic products through the wireless charging coil.

[0016] Furthermore, the box body includes an upper cover and a bottom shell. An upper inner liner is provided inside the upper cover, and the upper cover is fixedly connected to the upper inner liner. A bottom inner liner is provided inside the bottom shell, and the bottom shell is fixedly connected to the bottom inner liner. One end of the upper inner liner is rotatably connected to the bottom inner liner, and the other end is openably connected to the bottom inner liner, so that the upper cover and the bottom shell form a flip-top connection structure.

[0017] Furthermore, the lower end of the upper inner liner is provided with a rotating protrusion, and the two ends of the rotating protrusion are provided with rotating shafts. The upper end of the bottom inner liner is provided with a rotating position, and the side wall of the rotating position is provided with a shaft hole. The rotating protrusion is movably disposed in the rotating position, and the rotating shaft is movably disposed in the shaft hole.

[0018] Furthermore, the mounting slot is provided in more than one way, which can charge more than one dry cell battery at the same time.

[0019] Compared with existing technologies, the charging box of this utility model sets the positive and negative charging terminals at the same end of the charging compartment, and is compatible with batteries that can be charged at the same end. During charging, there is no need to press the two ends of the battery together, making charging more convenient. At the same time, this structural design of the charging box eliminates the need to set charging lines at both ends of the charging compartment, making the product structure and manufacturing process simpler. In addition, the display screen allows users to easily monitor the battery level at any time, making it more convenient to use. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] To achieve the above objectives, the technical solution of this utility model is as follows:

[0031] See Figure 1-7 As shown, this embodiment provides a charging box that can display the power level and charging at the same end, including: a box body 1, a control board 2, and a charging positive electrode 3 and a charging negative electrode 4 connected to the control board 2. The box body 1 is provided with a charging compartment 5 for placing the battery 100, and the charging positive electrode 3 and the charging negative electrode 4 are located at the same end of the charging compartment 5.

[0032] The outer side of the box 1 is also equipped with a display screen 9, which is electrically connected to the control board 2 and can be used to display the power of the battery 100, so that users can understand the charging status of the battery 100.

[0033] See Figure 8 This embodiment can be used with standard lithium-ion, nickel-metal hydride, and nickel-cadmium dry cell batteries of sizes 1.5V, 3V, and 9V (sizes 1, 2, 5, and 7) with both positive and negative electrodes on the same end. See also Figure 5 When the dry cell battery is installed in the charging compartment 5, the positive terminal 101 of the battery 100 contacts the positive charging terminal 3 of the charging compartment, and the negative terminal 102 of the battery 100 contacts the negative charging terminal 4 of the charging compartment. During charging, there is no need to press the two ends of the battery 100 together, making charging more convenient. At the same time, the charging compartment with this structural design does not need to have charging lines at both ends of the charging compartment 5, which simplifies the product structure and manufacturing process.

[0034] Specifically, the control board 2 uses a multi-functional PCB board with charge and discharge protection and charge and discharge control functions.

[0035] For details, see Figure 3The charging compartment 5 has an opening 51 at its upper end for inserting and removing the battery 100. The control board 2 is located at the lower end of the charging compartment 5. Correspondingly, the positive charging terminal 3 and the negative charging terminal 4 are mounted on the control board 2, also located at the lower end of the charging compartment 5. During charging, the user can insert the battery 100 into the charging compartment 5 through the opening 51. After charging, the user can remove the battery 100 through the opening 51. When inserting the battery 100, the positive and negative terminals at the lower end of the battery 100 connect to the positive charging terminal 3 and the negative charging terminal 4 of the charging compartment, respectively. As long as the lower end is firmly attached to the charging compartment 5, normal charging is guaranteed, making charging more convenient.

[0036] For details, see Figure 6 The control board 2 is provided with a first conductive post 6. The bottom of the first conductive post 6 is electrically connected to the control board 2, and the upper end of the first conductive post 6 forms a charging negative electrode 4. A through hole 61 is opened in the middle of the first conductive post 6. A second conductive post 7, which is separate from the first conductive post 6, is provided in the hole 61. The lower end of the second conductive post 7 is electrically connected to the control board 2, and the upper end of the second conductive post 7 forms a charging positive electrode 3.

[0037] Specifically, the first conductive post 6 adopts a ring-shaped column, and the second conductive post 7 adopts a conductive pin. The conductive pin is set inside the ring structure of the column and is separate from the column. This can ensure the stability of the charging structure and save the space occupied by the conductive pin, which helps to reduce the size of the product and facilitates the portable use of the product.

[0038] Specifically, the control board 2 is also connected to a bidirectional charging interface 8, which extends through and is exposed in the housing 1. In this embodiment, the charging box can both charge the standard battery 100 by connecting a regular 5V adapter through the bidirectional charging interface 8, and also charge external electronic products using the standard battery 100 through the bidirectional charging interface 8. This allows the charging box to simultaneously charge the battery 100 and power external electronic products, increasing the usage possibilities of the charging box and expanding its application scenarios.

[0039] Specifically, the bidirectional charging interface 8 adopts a standard Type-C interface, which integrates charging and discharging functions into one interface, avoiding the need to install multiple electrical interfaces on the housing 1. This simplifies the structure and makes the product more aesthetically pleasing. It should be noted that the bidirectional charging interface 8 is prior art, and its specific implementation method is not described in detail in this application.

[0040] Specifically, a wireless charging coil 10 is also installed on the box 1. The wireless charging coil 10 is electrically connected to the control board 2 and can wirelessly charge electronic products through the wireless charging coil 10.

One end of the upper inner liner 13 is rotatably connected to the bottom inner liner 14, and the other end is openably connected to the bottom inner liner 14, forming a flip-top connection structure between the upper cover 11 and the bottom shell 12. The openable / closed connection between the upper inner liner 13 and the bottom inner liner 14 can be achieved using a magnetic attraction method, which has the advantages of stable closure and convenient opening.

[0042] Specifically, the lower end of the upper inner liner 13 is provided with a rotating protrusion 15, and the two ends of the rotating protrusion 15 are provided with rotating shafts 16. The upper end of the bottom inner liner 14 is provided with a rotating position 17, and the side wall of the rotating position is provided with a shaft hole 18. The rotating protrusion 15 is movably disposed in the rotating position 17, and the rotating shaft 16 is movably disposed in the shaft hole 18.

[0043] Specifically, the inner side of the top cover 11 is provided with a first buckle groove 111, and the outer side wall of the upper inner liner 13 is provided with a first buckle 131. The first buckle 131 is engaged in the first buckle groove 111 to achieve a fixed connection between the top cover 11 and the upper inner liner 13.

[0044] Specifically, the inner side of the bottom shell 12 is provided with a second fastening groove 121, and the outer side wall of the bottom inner liner 14 is provided with a second buckle 141. The second buckle 141 is engaged in the second fastening groove 121 to achieve a fixed connection between the bottom shell 12 and the bottom inner liner 14.

[0045] Specifically, an installation groove is provided in the bottom inner liner 14, forming a charging compartment 5; the control board 2 is located at the bottom of the bottom inner liner 14, and the bottom of the installation groove has an opening, so that the upper ends of the first conductive post 6 and the second conductive post 7 can extend into the installation groove.
