[0035] In one embodiment of this utility model, such as Figure 1-3As shown, a battery tube structure for a stylus is provided, including a pen barrel 10. One end of the pen barrel 10 has a pen tip as a touch part, and the barrel body has a cross-section for easy gripping. The top of the pen barrel 10 is cylindrical. A battery tube 20 is disposed in the upper half of the pen barrel 10. The battery tube 20 is inserted into the pen barrel 10, and the top of the battery tube 20 protrudes from the pen barrel 10. A pen cap 30 is fitted over the protruding part of the battery tube 20, which encloses the battery tube 20 and is connected to the pen barrel 10.
[0036] The upper half of the pen barrel 10 is provided with an upward-opening mounting cavity 11. The shape of the mounting cavity 11 is consistent with the shape of the pen body of the pen barrel 10. The mounting cavity 11 is for inserting the battery tube 20 into the pen barrel 10.
[0037] The top of the pen barrel 10 is provided with a mating groove 12 around the mounting cavity 11. The depth of the mating groove 12 is less than the height of the cylindrical part at the top of the pen barrel 10, preferably 1-3 cm.
[0038] The mating groove 12 is provided with mating plates 13. There are multiple mating plates 13, which are arranged perpendicularly to the mating groove 12. The mating plates 13 divide the mating groove 12 into multiple slots. The number of mating plates 13 on at least one side of the mating groove 13 is different from the number on the other side. In this embodiment, each of the three sides of the mating groove 12 is provided with a mating plate 13, and the other side is not provided with a mating plate 13. This structural design allows the battery tube 20 to be well engaged with the pen tube 10 after it is inserted into the pen tube 10, and also prevents the battery from failing to supply power to the pen tube 10 due to incorrect orientation when the battery tube 20 is inserted into the pen tube 10.
[0039] The top of the pen barrel 10 is also provided with a mating block 14, which is a magnet.
[0040] like Figure 4-6 As shown, there are at least two battery tubes 20, one of which contains a fully charged battery for backup, and the other is placed in the pen barrel 10. The battery tube 20 is provided with a battery compartment 21 for battery installation. The battery compartment 21 is a through-hole structure that penetrates the battery tube 20. The length, width, and height of the battery compartment 21 are consistent with the length, width, and height of the battery, so that the battery can be placed in the battery compartment 21 in a tight fit.
[0041] A back plate 22 for blocking the battery is provided on one side of the battery compartment 21. A through hole 23 is provided in the back plate 22, which facilitates the removal of the battery from the battery compartment 21.
[0042] The battery tube 20 is located at two ends of the battery compartment 21, namely the first end 24 and the second end 25. The first end 24, which is adjacent to the battery compartment 21, is provided with an electrical connector 241, which serves to connect the battery to the circuit board in the pen barrel 10.
[0043] The first end 24 has a mounting groove 243 on its side, and a magnetic charging head 242 is installed in the mounting groove 243. When the battery is placed in the pen barrel 10, the magnetic charging head 242 can charge the battery. At the same time, after the battery tube 20 and the battery are removed, the battery is placed in the battery tube 20, and the magnetic charging head 242 can still charge the battery. When the spare battery tube 20 and the battery are put into the pen barrel 10, the stylus resumes normal use.
[0044] A sealing cap 251 is provided on the second end 25, and the outer contour shape of the sealing cap 251 is consistent with the outer contour shape of the second end 25. The sealing cap 251 and the second end 25 are an integral structure. The sealing cap 251 is sleeved on the second end 25, and the diameter of the sealing cap 251 is larger than the diameter of the second end 25. The sealing cap 251 includes a cap head 2511 and a cap body 2512. The cap head 2511 is located at the top of the pen barrel 10, and the cap body 2512 is sleeved in the pen barrel 10. A locking groove 2513 is provided in the cap body 2512. There are multiple locking grooves 2513, which are provided through the cap body 2512. The locking grooves 2513 divide the cap body 2512 into multiple parts. The number of locking grooves 2513 is the same as the number of mating plates 13. When the battery tube 20 is inserted into the pen barrel 10, the cap body 2512 is locked onto the mating plate 13 through the locking grooves 2513, so that the battery tube 20 is locked and connected to the pen barrel 10.
[0045] A reserved groove 2514 is formed between the sealing cap 251 and the second end 25. The reserved groove 2514 provides space for the sealing cap 251 to be inserted into the mating groove 12 inside the pen barrel 10. When the battery tube 20 is inserted into the pen barrel 10, the reserved groove 2514 is fitted onto the inner wall of the mating groove 12.
[0046] The second end 25 has two mating blocks 26 on both sides of the cut surface. The mating blocks 26 are magnets. When the battery tube 20 is inserted into the pen barrel 10, the mating blocks 26 and the mating blocks 14 are attracted to each other, strengthening the connection between the battery tube 20 and the pen barrel 10. At the same time, even if the battery tube 20 is repeatedly inserted and removed from the pen barrel 10, causing the sealing cap 251 and the mating plate 13 to fail to engage, the battery tube 20 can still be connected to the pen barrel 10 due to the attraction between the mating blocks 26 and the mating blocks 14.
[0047] The inner surface of the pen cap 30 is threaded, and the outer surface of the cylindrical part at the top of the pen barrel 10 is threaded. The pen cap 30 is connected to the pen barrel 10 through the threaded engagement. The design of the pen cap 30 can ensure the connection strength between the battery tube 20 and the pen barrel 10, avoid poor contact between the battery tube 20 and the pen barrel 10, and at the same time keep the pen barrel 10 in a sealed state to prevent water from entering the pen barrel 10.
[0048] The working principle of this utility model is as follows: A battery tube structure for a stylus. When the battery is depleted, the pen cap 30 is rotated and removed. Pulling the sealing cap 251 causes the battery tube 20 to be removed along with the battery. The spare battery tube 20 and battery are then inserted into the pen barrel 10. The sealing cap 251 engages with the mating plate 13. The mating block 14 and mating block 26 are magnetically connected, connecting the pen cap 30 to the pen barrel 10. The removed battery tube 20 is then connected to the charger via the magnetic charging head 242 for charging. When the battery is damaged, simply remove the battery tube 20, push the battery out through the through hole 23, and then insert a new battery.
[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
