Description

Technical Field

[0001] This utility model relates to the field of charging and discharging equipment technology, and in particular to a charging box that can display the power level during charging and discharging. Background Technology

[0002] Batteries are used in electrical devices to provide the necessary electrical energy for their operation. Batteries generally include disposable batteries and rechargeable batteries. Disposable batteries lose their value after use due to the depletion of their internal energy and must be discarded. With increasingly stringent environmental regulations, more and more users are opting for rechargeable batteries. Rechargeable batteries (also known as secondary batteries) are batteries that can be recharged and reused repeatedly. Unlike disposable batteries, they can be recharged after discharging, thus extending their lifespan.

[0003] However, due to the convenience of rechargeable batteries, they are often carried when going out. But for rechargeable batteries, in addition to carrying the rechargeable batteries, you also need to carry the charger and charging cable so that you can charge the rechargeable batteries after use. As the number of items carried increases, you need more storage space on the one hand, and you also need to ensure that the rechargeable batteries or chargers are not damaged due to bumps or other reasons during the process of carrying them.

[0040] like Figure 1-7 As shown, the present invention proposes a charging case that can display the power level during charging and discharging, comprising:

[0041] The box body 1 and the lid 2 are provided. One end of the lid 2 is hinged to one end of the box body 1. When the box body 1 is sealed, the other end of the lid 2 is engaged with the other end of the box body 1. In this invention, the other end of the box body 1 is provided with a locking block 12, and the other end of the lid 2 is provided with a locking arm 23. When the lid 2 is closed, the locking arm 23 engages with the locking block 12 to seal the lid 2 and the box body 1. In addition, an opening mark and a closing mark are provided on both sides of the locking block 12 to remind the user of the opening and closing direction.

[0042] The control board 3 is located inside the housing 1, and a placement body 4 is provided on the control board 3. The placement body 4 has several charging slots 41 and several indicator bodies 42, which are connected to the control board 3. An interface 5 passes through the other end of the housing 1 and connects to the control board 3. When carrying the rechargeable battery, it is placed in one of the charging slots 41 and its position is restricted within the slots. The housing 1 and the cover 2 work together to carry and protect the rechargeable battery. When charging or discharging is required, the charging cable 82 is connected to the interface 5, and a charging plug or electrical device is connected as needed. The charging and discharging of the battery is then performed under the control of the control board 3. In addition, during the charging and discharging process, the charging and discharging power is displayed by several indicators 42. In this utility model, each charging slot 41 has four indicators 42 to display the rechargeable battery power. Preferably, the four indicators 42 each represent 25% of the power. That is, during charging, each indicator 42 lit up represents an increase of 25% in power, until all four indicators 42 are lit up, indicating that the charging power is 100% and charging is complete. During discharging, each indicator light that goes out represents a decrease of 25% in power, until all four indicators 42 are off, indicating that there is no excess power in the rechargeable battery for discharging. Preferably, the indicators 42 are indicator lights.

[0043] In this invention, the control board 3 is equipped with a power management chip (PMIC) as in the prior art, which controls charging and discharging. In addition, the control board 3 is also equipped with a temperature detection module (NTC), which detects the temperature during the charging and discharging process and stops charging and discharging when the temperature is too high. Furthermore, positive and negative markings are provided at the bottom of several charging slots 41 to remind the user of the positive and negative polarity and avoid the rechargeable battery being placed in the wrong direction.

[0044] like Figure 8 and 9 As shown, a light is also provided on the box body 1, and the light is connected to the control board 3 and the polymer battery placed inside the box body 1. When the box cover 2 is opened, the sensor metal plate 21 on the box cover 2 separates from the contact sensor plate 33 inside the box body 1 that is connected to the control board 3, and the light automatically turns on; when the box cover 2 is closed, the sensor metal plate 21 on the box cover 2 contacts the contact sensor plate 33 inside the box body 1, and the light automatically turns off. This allows for better visibility of the rechargeable battery and the various components on the box body 1 when operating at night or in low-light conditions.

[0045] The technical solution of this utility model places the rechargeable battery in the charging slot 41, and uses the cooperation of the box body 1 and the box cover 2 to accommodate and protect the rechargeable battery. When charging and discharging are required, the charging cable 82 is connected to the interface 5, and the rechargeable battery is directly charged through a mobile phone plug, etc. The rechargeable battery placed in the charging slot 41 can be charged under the control of the control board 3. When discharging is required, the charging cable 82 is connected to the electrical device, and the electrical device is charged through the rechargeable battery under the control of the control board 3. Of course, when the rechargeable battery needs to be used, it can be taken out and directly put into the electrical device for use. Compared with the prior art, the technical solution of this utility model does not require an additional charger. The charging and discharging of the rechargeable battery can be completed through the cooperation of the box body 1, the box cover 2, the charging slot 41 and the control board 3. At the same time, the cooperation of the box body 1 and the box cover 2 protects the battery and avoids damage to the battery during carrying. In addition, the reduction of the overall number of components during carrying can further reduce the required storage space.

[0046] like Figure 4 and 5 As shown, this utility model also includes several limiting structures 6, which are disposed on one side of the control board 3 and are respectively connected to several charging slots 41; specifically, the number of limiting structures 6 is the same as the number of charging slots 41; a limiting structure 6 is provided at the location of each charging slot 41, and the charging battery in the charging slot 41 is limited by the limiting structure 6.

[0047] The limiting structure 6 includes a first elastic member 61 and a limiting piece 62. One end of the first elastic member 61 is disposed in a fixing groove on the control plate 3. Specifically, one end of the first elastic member 61 is provided with a connecting piece, which passes through the fixing groove. The fixing groove holds the connecting piece, thereby limiting one end of the first elastic member 61. The limiting piece 62 passes through the control plate 3 and the charging slot 41 in sequence and is connected to the other end of the first elastic member 61. When the rechargeable battery is placed in the charging slot 41, it compresses the limiting piece 62 and stretches the first elastic member 61. When the rechargeable battery is continuously charging... Inside the groove 41, the first elastic element 61 is always in a stretched state. Under the elastic deformation of the first elastic element 61, the limiting piece 62 is always in contact with the rechargeable battery. It should be noted that a positive electrode is provided in the charging groove 41 opposite to the limiting piece 62, and a negative electrode is provided on the limiting piece 62. The negative electrode on the limiting piece 62 is connected to the control board 3 via a wire (not shown in the figure). This allows the rechargeable battery to be charged or discharged as needed by the interaction between the negative electrode on the limiting piece 62 and the positive electrode in the charging groove 41. In this invention, the first elastic element 61 is preferably a spring.

[0048] In addition, to ensure the stability of the movement of the limiting piece 62 within the control plate 3 and the charging slot 41, in this invention, the control plate 3 is provided with a first sliding groove 31, and the charging slot 41 is provided with a second sliding groove 63; the limiting piece 62 passes through the first sliding groove 31 and the second sliding groove 63; through the cooperation of the first sliding groove 31 and the second sliding groove 63, the movement trajectory of the limiting piece 62 can be restricted, thereby improving the stability of the movement of the limiting piece 62.

[0049] Meanwhile, the slide plate 64 is disposed in the first slide groove 31, the limiting piece 62 is disposed on the slide plate 64, and a hook 65 is disposed on the slide plate 64, and the other end of the first elastic member 61 is disposed on the hook 65; in this utility model, the slide plate 64 is adapted to the first slide groove 31, so that when the limiting piece 62 moves, the stability of the limiting piece 62 can be further increased by the cooperation between the slide plate 64 and the first slide groove 31.

[0050] like Figure 2 As shown, a second elastic element 7 is provided inside the box body 1. One end of the second elastic element 7 is mounted on the control plate 3, and the other end of the second elastic element 7 is engaged with the box cover 2. In the sealed state, the box cover 2 and the control plate 3 work together to compress the second elastic element 7. At the same time, due to the cooperation of the locking block 12 and the locking arm 23, the second elastic element 7 is always in a compressed state. When the box cover 2 is opened, since there is no connection between the locking block 12 and the locking arm 23, the second elastic element 7 returns to its original position under the action of elastic deformation, and at the same time drives the box cover 2 to rotate on the box body 1, so that the box cover 2 opens automatically. Of course, the opening angle of the box cover 2 can be adjusted by adjusting the second elastic element 7 as needed. In this utility model, the preferred opening angle of the box cover 2 is 85°.

[0051] Specifically, the control panel 3 is provided with a slot 32, and one end of the second elastic element 7 passes through the slot 32; the lid 2 is provided with a first limiting protrusion and a second limiting protrusion, and the other end of the second elastic element 7 passes through the first limiting protrusion and the second limiting protrusion; through the cooperation of the first limiting protrusion and the second limiting protrusion, the second elastic element 7 can bear the force of the lid more evenly, and avoid the second elastic element 7 from deviating during use; preferably, the second elastic element 7 is a spring.

[0052] As shown in 1-5, the box body 1 is provided with a hanging hole 11, and a carrying mechanism 8 is provided on the hanging hole 11. The carrying mechanism 8 can better carry the box body 1. The carrying mechanism 8 includes a carrying rope bracket 81 and a charging cable 82. The carrying rope bracket 81 is set on the hanging hole 11 by a carrying rope. The two ends of the charging cable 82 are respectively set on the carrying rope bracket 81. When in the carrying state, the box body 1 can be carried by operating the charging cable 82. When in the charging and discharging state, the two ends of the charging cable 82 are removed from the carrying rope bracket 81, one end is connected to the interface 5, and the other end is connected to the charging head (such as a mobile phone charging head) or the electrical device (such as a mobile phone), and then the charging and discharging operation is realized under the control of the control board 3.

[0053] In this utility model, mounting grooves 83 are provided on both sides of the lifting rope bracket 81, and the two ends of the charging cable 82 are detachably installed in the mounting grooves 83 on both sides of the lifting rope bracket 81. Through the cooperation of the mounting grooves 83 and the charging cable 82, the quick assembly and disassembly of the two ends of the charging cable 82 from the lifting rope bracket 81 can be improved while restricting the positions of the charging ends. Figure 4 As shown, a latch 84 is also provided in the mounting slot 83. When both ends of the charging cable 82 are placed in the mounting slot 83, the latch 84 limits the two ends of the charging cable 82 to prevent the two ends of the charging cable 82 from easily coming off the mounting slot 83.

[0054] It should be noted that in this utility model, interface 5 is a TYPE-C interface 5; both ends of the charging cable 82 are TYPE-C connectors, which can better match the charging head or electrical equipment as needed.

[0055] like Figure 1 , 4 As shown in Figures 6 and 7, the dimensions of this invention can be adjusted as needed, thereby increasing its compatibility with rechargeable batteries and increasing the number of rechargeable batteries it can hold; for example... Figure 1 and 4 As shown, in Embodiment 1, charging slot 41 can hold rechargeable batteries of different sizes; CR123 batteries and 16340 batteries can be placed in charging slot 41. Figure 2 As shown, in Embodiment 2, the length of the charging slot 41 can be increased. With increased length, both CR123 and 18650 batteries can be accommodated. Figure 7 As shown, the number of charging slots 41 can be increased. After the number of charging slots 41 is increased, CR123 batteries and 18650 batteries can be placed. Of course, the size and number of charging slots 41 can also be adjusted as needed, and the size of the box body 1, the box cover 2 and the control board 3 can be adjusted accordingly, and the number of indicator bodies 42 can be adjusted according to the changes. The specific adjustments to the box body 1, the box cover 2 and the control board 3 are subject to actual conditions, and this utility model will not be further described.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
