Figure 1 As shown, the battery module 30 is clamped and fixed to the connection base 20. When charging, maintenance or replacement is required, the battery module 30 can be directly removed from the connection base 20, which improves the convenience of use.

[0016] Combination Figure 2 and Figure 3As shown, the battery module 30 is connected to the connection base 20 through a quick release assembly, and the quick release assembly includes a boss 40 and a cavity 31. When the boss 40 is inserted into the cavity 31 to form a detachable snap connection, the battery module 30 is fixed to the connection base 20. Figure 2 and Figure 3 In the embodiment of the present invention, the boss 40 is provided on the side of the connection base 20 facing the battery module 30, and the cavity 31 is provided on the side of the battery module 30 facing the connection base 20. In other embodiments, the cavity is provided on the side of the connection base facing the battery module, and the boss is provided on the side of the battery module facing the connection base, which can also realize the detachable clamping of the battery module and the connection base.

[0017] In some embodiments, in combination Figure 2 and Figure 3 As shown, the boss 40 is provided with at least one radial latch 41, and the inner wall opening of the cavity 31 is correspondingly provided with an arc-shaped baffle 32. Figure 2 and Figure 3 In the example, there are two latching tongues 41 arranged opposite to each other, and there are two corresponding baffles 32, and the baffles 32 correspond to the latching tongues 41 one by one. When the latching tongues 41 are respectively connected to the baffles 32, the firmness of the connection can be improved. In other examples, there can be more than two latching tongues, and the baffles correspond to the latching tongues one by one.

[0018] In some embodiments, in combination Figure 2 and Figure 3 As shown, the baffle plate 32 extends in the axial direction, and the space at the outer end of the baffle plate 32 in the circumferential direction serves as an insertion opening 321 for the latch tongue 41 . Figure 2 and Figure 3 There are two opposing baffles 32 in the example, so the space between the two baffles 32 is the insertion opening 321 for the latch 41 to penetrate. When installing the battery module 30, when the boss 40 is inserted into the cavity 31, the latch 41 correspondingly penetrates into the cavity 31 from the insertion opening 321. After the latch 41 passes over the baffle 32, the battery module 30 is rotated, that is, the boss 40 and the cavity 31 rotate relative to each other until the latch 41 is located inside the corresponding baffle 32, at which time the boss 40 and the cavity 31 form a snap connection.

[0019] In some embodiments, in combination Figure 2 and Figure 3As shown, the inner wall of the cavity 31 is provided with two upper and lower positioning protrusions 33, and the circumferential outer wall of the tongue 41 of the boss 40 is provided with positioning recesses 42 corresponding to the positioning protrusions 33, that is, there are two corresponding positioning recesses 42.

At this time, the tongue 41 is stuck by the positioning protrusion 33, so that the boss 40 is not easy to rotate relative to the cavity 31, that is, the battery module 30 is not easy to rotate relative to the connecting seat 20 by itself, and the battery module 30 is not easy to detach from the connecting seat 20 by itself, thereby improving the installation stability of the battery module 30 on the connecting seat 20. In other embodiments, only one positioning protrusion can also be provided.

[0020] In some embodiments, in combination Figure 2 and Figure 3 As shown, two positioning protrusions 34 are provided in the cavity 31, and a positioning groove 43 is provided on the side of the boss 40 facing the cavity 31, and the positioning groove 43 corresponds to the positioning protrusion 34 one by one. When installing the battery module 30, the boss 40 is inserted into the cavity 31 and the boss 40 and the cavity 31 are relatively rotated until the positioning protrusion 33 is inserted into the corresponding positioning recess 42, and the positioning protrusion 34 is just placed in the corresponding positioning groove 43, which helps to maintain the relative position between the boss 40 and the cavity 31. In other embodiments, only one positioning protrusion may be provided.

[0021] In some embodiments, in combination Figure 2 and Figure 3 As shown, the side of the boss 40 facing the cavity 31 is also provided with two pre-positioning recesses 44, and the pre-positioning recesses 44 correspond to the positioning protrusions 34 one by one. When installing the battery module 30, the boss 40 is inserted into the cavity 31, and when the latch 41 is inserted from the insertion port 321, the positioning protrusion 34 is placed in the pre-positioning recess 44, and the battery module 30 can be rotated to allow the latch 41 to rotate to the inside of the baffle 32. The shape and size of the pre-positioning recess 44 are adapted to the shape and size of the positioning protrusion 34, and each edge of the pre-positioning recess 44 is provided with a rounded transition to reduce the resistance of the boss 40 to the positioning protrusion 34 when rotating.

[0022] In some embodiments, in combination Figure 2 and Figure 3As shown, the side of the boss 40 facing the cavity 31 is provided with two elastic contacts 45 for conducting electricity, and the cavity 31 is provided with two metal sheets 35 for conducting electricity, and the elastic contacts 45 correspond to the metal sheets 35 one by one. When installing the battery module 30, the boss 40 is inserted into the cavity 31 and the boss 40 and the cavity 31 are relatively rotated until the positioning protrusion 33 is inserted into the corresponding positioning recess 42, the boss 40 and the cavity 31 form a snap connection, and the elastic contacts 45 and the metal sheets 35 abut against each other to form an effective electrical connection. In addition, as Figure 3 As shown, the metal sheet 35 is arranged in a transverse plate 38 in the concave cavity 31. And two positioning protrusions 34 are also arranged on the transverse plate 38.

[0023] In some embodiments, Figure 2 As shown, a charging circuit board 36 and a battery 37 are provided in the battery module 30, and the charging circuit board 36 is electrically connected to the battery 37 and the metal sheet 35 ( Figure 3 The charging circuit board 36 is also provided with a charging interface 361, which is connected to an external wiring harness and an external charger to charge the battery 37.

The seat tube 10 has a built-in hydraulic rod 50. The cylinder body 51 of the hydraulic rod 50 is fixed in the lower tube 12, and the piston rod 52 of the hydraulic rod 50 penetrates into the upper tube 11. The upper tube 11 has a built-in driving mechanism 60. The driving mechanism 60 is used to press down the operating rod 53 in the piston rod 52. After the operating rod 53 is pressed down, the piston rod 52 of the hydraulic rod 50 can move up and down without restriction, so that the position of the upper tube 11 can be adjusted. When the battery module 30 is installed on the connecting seat 20, the metal sheet 35 ( Figure 3 ) and elastic contact 45( Figure 2 ) is electrically connected, the elastic contact 45 is electrically connected to the drive mechanism 60, and the drive mechanism 60 is electrically connected to the battery module 30 and is powered by the battery module 30.

[0025] In some embodiments, in combination Figure 4 and Figure 5As shown, a mounting tube 70 is built-in and fixed on the upper part of the upper tube 11, and the connecting seat 20 is fixedly connected to the top of the mounting tube 70 by screws.
