Technical Field

[0001] The utility model relates to the technical field of energy storage, and in particular to a charging sleeve. Background Art

[0002] In order to reduce the cost of using batteries, rechargeable batteries were born. Earlier, they needed to be charged by adding an additional charging station, which was inconvenient. In order to facilitate battery charging, the type-C charging port, which is the same as the mobile phone interface, is a more popular method. Consumers only need to use the mobile phone charging cable to charge the battery. Although this method makes charging more convenient, it requires the battery's own space to set up a charging port, which not only increases the size of the battery, but also makes it difficult to make room for additional charging ports for some batteries with limited space.

[0025] like Figure 1-Figure 4 As shown, Figure 1 It is a schematic diagram of the three-dimensional structure of the charging case; Figure 2 is another three-dimensional structural schematic diagram of the charging case; Figure 3 is a cross-sectional schematic diagram of a charging case; Figure 4 The charging sleeve of the present application includes a sleeve body 201, which is sleeved on one end of the battery and charged by an external power source.

[0026] The sleeve 201 has a mounting groove 2011, a charging port 2012 and a circuit board 2013. The battery card is arranged in the mounting groove 2011, and the circuit board 2013 is arranged in the charging port 2012. The circuit board 2013 is connected with the battery in the mounting groove 2011. In specific application, the sleeve 201 is cylindrical, and the mounting groove 2011 is opened along the axial direction of the sleeve 201. The charging port 2012 is located at one end of the sleeve 201 away from the mounting groove 2011, or the charging port 2012 is opened on the outer surface of the sleeve 201. Furthermore, the battery and the mounting groove 2011 are detachably connected. When the battery needs to be charged, the battery is inserted into the mounting groove 2011 of the sleeve 201; after the battery is charged, the battery is taken out from the mounting groove 2011.

[0027] Preferably, a buffer 20111 is further provided in the mounting groove 2011, and the buffer 20111 is arranged along the inner wall surface of the mounting groove 2011. When the battery is inserted into the mounting groove 2011, the buffer 20111 is located between the inner wall surface of the mounting groove 2011 and the outer surface of the battery. The outer surface of the battery is protected by the buffer 20111 to prevent the inner wall surface of the mounting groove 2011 from causing wear to the outer surface of the battery. Specifically, the buffer 20111 is made of soft material, such as plastic or silicone material.

[0028] In this embodiment, the shape of the charging port 2012 can be adapted according to the external power source. For example, the shape of the charging port 2012 is adapted to the type-C connector, that is, the common type-C connector can be inserted into the charging port 2012 and connected to the circuit board 2013 for electrical conduction. Of course, the charging port 2012 adapted to other connectors can also be selected, not limited to the type-C connector.

[0029] The circuit board 2013 has a positive electrode 20131 and a negative electrode 20132. One end of the positive electrode 20131 is connected to the circuit board 2013, and the other end thereof extends into the mounting groove 2011. One end of the negative electrode 20132 is connected to the circuit board 2013, and the other end thereof extends into the mounting groove 2011. When the battery is inserted, the positive electrode 20131 is conductively connected to the positive electrode of the battery, and the negative electrode 20132 is conductively connected to the negative electrode of the battery, so that the circuit board 2013 and the battery are conductive. Specifically, the positive electrode 20131 and the negative electrode 20132 are both conductive wires, such as cables, or copper wires or other metal wires are directly used. Furthermore, the charging sleeve also has a positive electrode channel 2014, which is connected to the charging port 2012 and the mounting groove 2011, respectively, and the positive electrode member 20131 is located in the positive electrode channel 2014. The positive electrode channel 2014 is arranged to facilitate the rapid extension of the positive electrode member 20131 to the mounting groove 2011, and at the same time, it also protects the positive electrode member 20131. Similarly, the charging sleeve also has a negative electrode channel 2015, which is spaced apart from the positive electrode channel 2014, and the negative electrode channel 2015 is connected to the charging port 2012 and the mounting groove 2011, respectively, and the negative electrode member 20132 is located in the negative electrode channel 2015.

[0030] Furthermore, the charging sleeve also has a clamping groove 2016, which is connected to the mounting groove 2011. When the battery is inserted into the mounting groove 2011, the positive electrode of the battery is inserted into the clamping groove 2016, thereby improving the stability of the connection between the sleeve 201 and the battery. In specific applications, the clamping groove 2016 is connected to the positive electrode channel 2014, that is, one end of the positive electrode member 20131 passes through the positive electrode channel 2014 and the clamping groove 2016 and then extends into the mounting groove 2011. Preferably, the outer surface of the clamping groove 2016 near the mounting groove 2011 is provided with a clamping slope 20161, and the cross-section of the clamping slope 20161 is in an inverted "eight" shape, or can be understood as a trumpet shape, wherein the diameter of the clamping slope 20161 gradually decreases along the direction close to the mounting groove 2011, so as to improve the clamping effect of the clamping groove 2016 on the positive electrode of the battery.

[0031] In another embodiment, the charging sleeve further has a magnetic member 2017, which is located in the clamping groove 2016, and the positive electrode member 20131 is connected and conductive with the magnetic member 2017. When the positive electrode of the battery is inserted into the clamping groove 2016, the magnetic member 2017 is adsorbed and connected with the positive electrode of the battery. The arrangement of the magnetic member 2017 not only allows the positive electrode member 20131 to be quickly connected with the positive electrode of the battery, but also reduces the risk of the positive electrode member 20131 not being in contact with the positive electrode of the battery. Specifically, the magnetic member 2017 is a magnet.

[0032] When the battery needs to be charged, one end of the battery is inserted into the mounting slot 2011, and at the same time, the positive electrode of the one end is inserted into the clamping slot 2016, the magnetic member 2017 is adsorbed on the positive electrode of the battery, and the negative electrode member 20132 is in contact with and connected to the negative electrode of the battery, and then the external power supply is inserted into the charging port 2012 and connected to the circuit board 2013, and the battery can be charged. After charging is completed, the sleeve 201 can be pulled out from one end of the battery.

[0033] Further explanation, the battery structure in this embodiment is as follows: one end of the battery has a positive column, the positive column protrudes from the end face of the battery, the positive column is the positive electrode of the battery, and is inserted into the clamping groove 2016; the battery is provided with a surrounding negative electrode structure on the same end face of the positive column, and the negative electrode structure is connected and conductive with the negative electrode member 20132. The circuit board 2013 is a product used in existing charging ports, which will not be elaborated here.

[0034] In summary, when the battery needs to be charged, one end of the battery is inserted into the mounting slot 2011, the positive electrode 20131 is connected to the positive electrode of the battery, the negative electrode 20132 is connected to the negative electrode of the battery, and the external power supply is inserted into the charging port 2012. The battery is charged through the circuit board 2013, the positive electrode 20131 and the negative electrode 20132; after the charging is completed, the battery can be taken out of the mounting slot 2011. In this way, the battery charging requirements are met without increasing the size of the battery, and the problem that the battery cannot be provided with a charging port 2012 due to insufficient space is solved, and it is suitable for most batteries.
