[0023] The preferred embodiments of this utility model will be described in detail with reference to the accompanying drawings.

[0024] Figures 1 to 7 This is a preferred embodiment of a foldable battery box vertical tube provided by this utility model. For example... Figures 1 to 7 As shown, the battery box vertical tube includes a tube body 10, within which a battery cavity 11 for housing the battery is formed. A handle mounting seat 20 is detachably installed on the top of the tube body 10. A front fork connecting seat 30 is rotatably connected to the bottom of the tube body 10 via a rotating shaft 12. A locking mechanism 40 is also provided between the front fork connecting seat 30 and the tube body 10. The locking mechanism 40 includes a rotating handle 41 movably mounted on the front fork connecting seat 30, a pin seat 42 on the rotating handle 41, and a slot 1 on the outer wall 10 of the tube body that mates with the pin seat 42. 3; The battery box and the vertical tube are integrated into one unit, and the internal space of the vertical tube is used to store the battery, reducing the weight of the vehicle. When locking, turn the rotating handle 41 close to the tube body 10, and the pin seat 41 on the rotating handle 41 is inserted into the slot 13 on the tube body 10 to prevent the fork connector 30 from separating from the tube body 10, ensuring riding safety. When folding is required, separate the pin seat 42 on the rotating handle 41 from the slot 13, and then rotate the tube body 10 around the pivot 12 to fold it, reducing the height and making it easy to fold and carry.

[0025] like Figures 1 to 7As shown, to further enhance safety, the locking mechanism 40 also includes an insert 43. The fork connector 30 has a first mounting groove 31, and the outer wall of the tube 10 has a second mounting groove 14. The first mounting groove 31 and the second mounting groove 14 together form a mounting groove 401 for housing the insert 43. Thus, during locking, the insert 43 is embedded in the mounting groove 401, preventing the fork connector 30 from separating arbitrarily from the tube 10. When folding is required, the insert 43 can be removed from the mounting groove 401 without affecting the rotation between the tube 10 and the fork connector 30. The shape of the insert 43 can be set as needed, preferably X-shaped, with the corresponding mounting groove 401 also being X-shaped, resulting in even force distribution.

[0026] The bottom of the tube body 10 extends to form a base 15 that is movably connected to the fork connector 30. One side of the base 15 extends to form an outer pivot support 151, and a second mounting slot 14 is provided on the other side of the base 15. One side of the fork connector 30 forms an inner pivot support 32, and a first mounting slot 31 is provided on the other side of the fork connector 30. Both the outer pivot support 151 and the inner pivot support 32 are provided with pivot holes 121 for pivot insertion. The rotating handle 41 is provided with a handle through hole 4103 for pivot to pass through. The rotating handle 41 and the mounting slot 401 are respectively located on both sides of the tube body 10. In this way, the rotating handle 41 and the mounting base 43 form a double lock for the tube body 10 and the fork connector 30, increasing safety.

[0027] like Figure 4 As shown, the bottom of the tube body 10 is provided with a fixing hole seat 16, and a fixing hole 161 is provided in the fixing hole seat 16. A fixing locking pin 44 is installed in the fixing hole 161. An installation bolt 431 that cooperates with the fixing locking pin is installed on the inlay seat 43. A second elastic element 45 is provided between the fixing locking pin 44 and the inlay seat 43 for popping the inlay seat 43 out of the placement groove 401. In this way, after the inlay seat 43 is placed in the placement groove 401, in order to prevent the inlay seat 43 from falling out of the placement groove 401 during the ride, the installation bolt 431 can be used to cooperate with the fixing locking pin 44 to further lock the inlay seat 43. When the inlay seat 43 is placed into the placement groove 401, the inlay seat 43 and the fixing locking pin 44 form a compression on the second elastic element 45. When the installation bolt 431 separates from the fixing locking pin 44, the second elastic element 45 returns to its original position, and the inlay seat 43 can be popped out of the placement groove 401, thereby avoiding the need for additional tools to remove it, which is convenient for the user.

[0028] like Figure 5 and Figure 6As shown, the fixing pin 44 is inserted into the fixing hole 161. One end of the fixing pin 44 forms a screw hole 441 that mates with the mounting bolt 431, and the other end forms a mounting hole 442. At least one positioning piece 46 is fitted on the rotating shaft 12. One end of the positioning piece 46 has a first positioning hole 461 that mates with the rotating shaft 12, and the other end has a second positioning hole 462. The second positioning hole 462 and the mounting hole 442 are connected by bolts. In this way, the fixing pin 44 is installed on the positioning piece 46, which positions the fixing pin 44 and prevents the fixing pin 44 from shifting when the screw hole 441 of the fixing pin 44 mates with the mounting bolt 431. Figure 3 As shown, two positioning plates 46 are fitted on the rotating shaft 12, the handle 41 is located between the two positioning plates 46, and the other end of the fixing pin 44 is located between the second positioning holes 462 on the two positioning plates 46. The positioning plates 46 and the fixing pin 44 are then installed with bolts.

[0029] The diameter of the first positioning hole 461 is larger than the diameter of the rotating shaft 12; the rotating handle 41 includes a handle rotating seat 4101 and a handle body 4102 disposed on the handle rotating seat 4101, the handle through hole 4103 is disposed at a non-central position of the handle rotating seat 4101, and the bottom of the handle rotating seat 4101 forms a cam seat for pushing the fixing locking pin 44; thus, when the handle body 4101 drives the handle rotating seat 4101 to rotate around the rotating shaft 12 away from the tube body 10, the cam seat at the bottom of the handle rotating seat 4101 pushes the fixing locking pin 44 forward, since the diameter of the first positioning hole 461 is larger than the diameter of the rotating shaft 12. The diameter of the shaft is 12. A gap is left between the first positioning hole 461 and the rotating shaft 12, so that when the handle rotating seat 4101 pushes the fixing pin 44, it will drive the positioning piece 46 and the fixing pin 44 to move closer to the inlay seat 43, further squeezing the second elastic member 45. When the mounting bolt 431 separates from the fixing pin 44, the second elastic member 45 resets, and the inlay seat 43 can be popped out from the placement slot 401. When installing the inlay seat 43, because the inlay seat 43 squeezes the second elastic member 45, the second elastic member 45 pushes the fixing pin 44 to move backward, thereby moving the positioning piece 46 and the fixing pin 44 away from the inlay seat 43.

[0030] The rotating handle 41 is provided with a slide 411 for controlling the up and down movement of the pin. The slide 411 is connected to an elastic pressing member 412 for pressing the pin seat 42. When locking, the slide 411 controls the up and down movement of the pin seat 42. When the pin seat 42 is inserted into the slot 13, the elastic pressing member 412 presses on the pin seat 42 to prevent the pin seat 42 from being arbitrarily separated from the slot 13.

[0031] like Figure 7As shown, the slide 43 and the pin seat 42 are respectively disposed on both sides of the handle body 4102 of the rotating handle 41. The slide 411 and the pin seat 42 move synchronously. The handle body 4102 of the rotating handle 41 is provided with a through-hole 4104, and an elastic pressing element 412, which is a return spring, is placed in the through-hole 4104. A screw 101 is provided on the outer wall of the tube body 10, and a slot 13 for the pin seat to be inserted is formed between the screw 101 and the outer wall of the tube body. When locking, the handle 41 is rotated around the rotating shaft 12 to Near the outer wall of the tube, align the slide block 411 with the slot 13 on the outer wall of the tube, push the slide block 411 upward, causing the pin seat 42 to move upward simultaneously, squeezing the elastic pressing member 412, releasing the slide block 411, and under the action of the elastic pressing member 412, causing the slide block 411 and the pin seat 42 to move downward, and the pin seat 42 to insert into the slot 13; when unlocking, push the slide block 411 upward, causing the pin seat 42 to move upward simultaneously, and the pin seat 42 to separate from the slot 13, and then rotate the rotating handle 41 around the rotating shaft 12 to a position away from the outer wall of the tube.

[0032] The tube 10 has an opening at the top and a tray 15 at the bottom for supporting batteries. The tray 15 has a cable routing port 152. The entire tube 10 is triangular prism-shaped, which facilitates the storage of a large number of batteries 100.

[0033] The handle mounting base 20 includes a handle base 21 and a handle cover 22. A shaft hole 23 for mounting the handle shaft is formed between the handle base 21 and the handle cover 22. The handle base 21 and the handle cover 22 are installed together by bolts. The handle base 21 is installed on the top of the tube body 10 by bolts. This allows the handle mounting base 20 to be disassembled and installed at any time, making it convenient to replace the battery 100.

[0034] The locking process of the battery box vertical tube is as follows: 1) Rotate the tube body 10 and the fork connecting seat 30 around the rotating shaft 12 to the same axis, and the first mounting groove 31 and the second mounting groove 14 together form the mounting groove 401; 2) Rotate the rotating handle 41 to be close to the tube body 10, push the slide 411 upward, drive the pin seat 42 to move upward synchronously, squeeze the elastic pressing member 412, release the slide 411, and under the action of the elastic pressing member 412, drive the slide 411 and the pin seat 42 to move downward, and insert the pin seat 42 into the slot 13; 3) Place the inlay seat 43 in the mounting groove 401, squeeze the second elastic member 45, and use the mounting bolt 431 and the fixing locking pin 44 to position and lock the inlay seat 43.

[0035] The unlocking and folding process of the battery box vertical tube is as follows: 1) Push the slide 411 on the rotating handle 41 upward, drive the pin seat 42 to move upward synchronously, squeeze the elastic pressing member 412, and the pin seat 42 on the rotating handle 41 separates from the slot 13. Rotate the rotating handle 41 around the rotating shaft 12 to a position away from the outer wall of the tube body 10; 2) Move the pushing and fixing pin 44 at the bottom of the rotating handle 41 forward, further squeeze the second elastic member 45. After the mounting bolt 431 separates from the fixing pin 44, the second elastic member 45 resets, and the insert seat 43 can be popped out from the placement slot 401; 3) Rotate the tube body 10 and the front fork connecting seat 30 around the rotating shaft 12 to a non-coaxial position to realize the folding of the tube body 10 and the front fork connecting seat 30.
