[0037] like Figures 1 to 12 As shown, Figures 1 to 12As shown, a preferred embodiment of the present invention provides a battery having two intersecting directions, a first direction X and a second direction Y, and includes a bracket 1, a battery body 2, and a lock body 3. For ease of explanation, the length direction of the battery body 2 is defined as the first direction X, and the height direction of the battery body 2 is defined as the second direction Y. The bracket 1 serves as a mounting carrier, as shown... Figure 1 As shown, to facilitate the installation and positioning of the battery body 2, the bracket 1 has an installation groove 11 extending along the first direction X. One end of the installation groove 11 in the first direction X has a limiting boss 111, and the other end of the installation groove 11 in the first direction X has a slot 112. The battery body 2 is placed in the installation groove 11, with one end of the battery body 2 in the first direction X engaging with the limiting boss 111, and the other end of the battery body 2 in the first direction X having a sliding groove 21. The lock body 3 is located at the end of the battery body 2 near the slot 112, and is used to cooperate with the limiting boss 111 to limit the battery body 2 in the first direction X. Specifically, as shown... Figures 1 to 10 As shown, the lock body 3 includes a bolt 31, an elastic element 32, and a lever 33. The bolt 31 and the elastic element 32 are located in the slide groove 21. One end of the bolt 31 in the first direction X is positioned towards the slot 112, and the other end of the bolt 31 in the first direction X abuts against the elastic element 32. The other end of the elastic element 32 in the first direction X abuts against the end face of the slide groove 21. The elastic element 32 has a tendency to drive the bolt 31 to move towards the slot 112. In order to facilitate the unlocking operation of the bolt 31, the lever 33 is located at the end of the battery body 2 away from the bracket 1 in the second direction Y, and the lever 33 is connected to the bolt 31. In practical applications, the locking tongue 31 has a locking position and an unlocking position. The locking tongue 31 is subjected to the elastic force of the elastic element 32, and a part of the locking tongue 31 is located in the slot 112 to be in the locking position. When unlocking is required, the locking tongue 31 is moved along the first direction X and away from the slot 112 by adjusting the toggle element 33. The locking tongue 31 is disengaged from the slot 112 to switch to the unlocking position. At this time, the elastic element 32 is in a compressed state.

[0038] When it is necessary to remove the battery body 2 from the mounting slot 11, the anti-theft lock 5 is opened. The bolt 31 of the lock body 3 is in the locked position under the elastic force of the elastic member 32. The battery body 2 is still in the mounting slot 11. Then, the lever 33 is adjusted by hand to move the bolt 31 along the first direction X and away from the slot 112. The bolt 31 compresses the elastic member 32 and disengages from the slot 112 to switch to the unlocked position. Since the hand always supports the battery body 2 when adjusting the lever 33 to unlock, the battery body 2 is prevented from falling directly from the mounting slot 11, which improves the safety of disassembling the battery body 2. At the same time, the lever 33 is located at the end of the battery body 2 away from the bracket 1 in the second direction Y. The lever 33 is connected to the bolt 31. When unlocking the bolt 31, it is not easily restricted by the structure of the battery and the lower tube 6, making the unlocking operation easier.

[0039] Furthermore, in order to protect the battery surface, such as Figure 1 As shown, it also includes a cover plate 4, which is located on the side of the battery body 2 away from the mounting groove 11. The cover plate 4 has a countersunk hole 41, and the actuating member 33 is located within the countersunk hole 41. Furthermore, to facilitate the connection between the actuating member 33 and the latch 31, and to perform locking and unlocking operations on the latch 31 by adjusting the movement of the actuating member 33 in the first direction X, as shown... Figures 3 to 10 As shown, the slide groove 21 includes a first groove 211 and a second groove 212. The first groove 211 extends in the first direction X, and the elastic member 32 is located within the first groove 211. The second groove 212 extends in the second direction Y and communicates with the first groove 211. The locking tongue 31 includes a locking portion 311 and a connecting portion 312. The locking portion 311 extends in the first direction X and is at least partially located within the first groove 211. One end of the locking portion 311 abuts against the elastic member 32, and the other end is disposed towards the slot 112. One end of the connecting portion 312 is located within the second groove 212 and connected to the locking portion 311, and the other end extends to the countersunk hole 41 and connects with the actuating member 33. Figure 6 As shown, when the anti-theft lock 5 is opened, the top of the battery body 2 tilts within the mounting groove 11 under its own weight. At this time, the locking part 311 slides within the slot 112 and engages with the side wall of the slot 112 to lock it in place. When it is necessary to remove the battery body 2, the adjusting toggle 33 drives the bolt 31 to move along the first direction X and away from the slot 112. The bolt 31 disengages from the slot 112 to switch to the unlocked position. First, the end of the battery body 2 closest to the slot 112 is moved out of the mounting groove 11, and then the entire battery body 2 can be removed.

[0040] Furthermore, in order to simplify the structure of the elastic element 32 and reduce production costs, in some embodiments, the elastic element 32 is a spring. In order to limit the elastic element during installation and improve the overall stability of the lock body 3 structure, the bottom of the first groove 211 is provided with a guide post 2111 for limiting the spring installation. That is, one end of the spring is sleeved on the guide post 2111, so as to limit the spring during compression and reset.

[0041] Furthermore, in order to facilitate the movement and limiting of the locking part 311 and prevent the locking part 311 from shifting its position when moving within the first groove 211, such as... Figure 3 , Figure 6 , Figure 7 As shown, it also includes a limiting block 34. The second groove 212 is provided with an installation step 2121 corresponding to the limiting block 34. Specifically, the limiting block 34 cooperates with the side wall of the first groove 211 at one end face in the second direction Y to limit the movement of the locking part 311 in the first direction X.

[0042] Furthermore, to facilitate the installation of the battery body 2, the locking part 311 snaps into the slot 112, reducing assembly difficulty, such as... Figure 3 , Figure 7 As shown, the locking part 311 has a guide slope 3111 at one end near the slot 112 in the first direction X, and the guide slope 3111 is inclined in a direction away from the toggle member 33.

[0043] Furthermore, the end of the battery body 2 furthest from the lock body 3 in the first direction X is engaged with the limiting boss 111. This is done to reduce the overall size of the bracket 1 and simplify the engagement structure, such as... Figure 4 As shown, the battery body 2 has a limiting groove 22 corresponding to the limiting boss 111 at one end in the first direction X. That is, the battery body 2 is restricted in the mounting groove 11 by the limiting boss 111 cooperating with the limiting groove 22 and the locking tongue 31 cooperating with the slot 112, so as to prevent the battery body 2 from coming out of the mounting groove 11.

[0044] Furthermore, to facilitate the placement of the anti-theft lock 5 and the unlocking of both the anti-theft lock 5 and the lock body 3, such as... Figure 3 As shown, the anti-theft lock 5 is located at one end of the bracket 1 in the first direction X, near the lock body 3, and the battery body 2 has a lock hole 23 corresponding to the anti-theft lock 5. That is, the anti-theft lock 5 and the lock body 3 are arranged adjacent to each other, so that when the anti-theft lock 5 is opened, it is easy to unlock the lock body 3.

[0045] Furthermore, in order to simplify the structure of the locking tongue 31, such as Figure 3 As shown, the projection of the locking tongue 31 onto the plane parallel to the first direction X and the second direction Y is T-shaped or L-shaped, which can be adjusted according to actual design requirements. When the projection of the locking tongue 31 onto the plane parallel to the first direction X and the second direction Y is T-shaped, the end of the locking part 311 away from the slot 112 can be used for positioning when the elastic element 32 is installed, thereby improving the overall assembly accuracy of the lock body 3.

[0046] This utility model also provides a frame, including the battery of any of the above-mentioned types, and further including a lower tube 6 and a head tube 7. To facilitate the installation and positioning of the bracket 1, as follows... Figure 11 , Figure 12 As shown, a mounting cavity 61 is provided inside the lower tube 6, and the bracket 1 is disposed in the mounting cavity 61 and connected to the lower tube 6. The bracket 1 and the lower tube 6 are fixedly connected by screws. Furthermore, this utility model also provides an electric bicycle, including the above-mentioned frame.

[0047] In summary, this utility model embodiment provides a battery, a frame, and an electric bicycle, including a bracket 1, a battery body 2, and a lock body 3. The bracket 1 has a mounting groove 11, with a limiting boss 111 at one end in the first direction X, and a slot 112 at the other end in the first direction X. The battery body 2 is disposed within the mounting groove 11, with one end in the first direction X engaging with the limiting boss 111, and the other end in the first direction X having a sliding groove 21. The lock body 3 is disposed at the end of the battery body 2 near the movable groove, and includes a latch 31, an elastic element 32, and a toggle element 33. The latch 31 is disposed in the sliding groove 21, with one end in the first direction X facing the slot 112, and the other end in the first direction X abutting against the elastic element 32. The other end of the elastic element 32 abuts against the end face of the sliding groove 21, and the elastic element 32 tends to drive the latch 31 towards the slot 112. The latch 31 has a locking position and an unlocking position. When the battery body 2 needs to be removed from the mounting slot 11, the anti-theft lock 5 is opened. The latch 31 of the lock body 3 is in the locking position under the elastic force of the elastic member 32, and the battery body 2 is still in the mounting slot 11. Then, the lever 33 is adjusted by hand to move the latch 31 along the first direction X and away from the slot 112. The latch 31 compresses the elastic member 32 and disengages from the slot 112 to switch to the unlocking position. Since the hand always supports the battery body 2 when adjusting the lever 33 to unlock, the battery body 2 is prevented from falling directly from the mounting slot 11, which improves the safety of disassembling the battery body 2. At the same time, the lever 33 is located at the end of the battery body 2 away from the bracket 1 in the second direction Y. The lever 33 is connected to the latch 31. When unlocking the latch 31, it is not easily restricted by the structure of the battery and the lower tube 6, making the unlocking operation easy.
