[0018] In this implementation: It includes the inclined beam 1 of an electric bicycle. The inclined beam 1 of the electric bicycle is located in the middle part of the electric bicycle, connecting the front end and the rear end of the bicycle. It is an important part of the electric bicycle frame. The end of the inclined beam 1 of the electric bicycle connected to the front end of the bicycle is at a higher position, while the end connected to the rear end of the bicycle is at a lower position. The inclined beam 1 of the electric bicycle includes a support inclined beam one 2, a battery fixing cylinder 3, a support inclined beam two 4, and a movable cylinder 5. One end of the support inclined beam one 2 is connected to the rear end of the bicycle, and one end of the support inclined beam two 4 is connected to the front end of the bicycle. The position of the support inclined beam two 4 is higher than that of the support inclined beam one 2, and the support inclined beam two 4 and the support inclined beam one 2 are on the same straight line. The diameters of the support inclined beam one 2 and the support inclined beam two 4 are the same. One end of the battery fixing cylinder 3 is fixedly connected to the support inclined beam one 2. The diameter of the battery fixing cylinder 3 is smaller than that of the support inclined beam one 2, and the battery fixing cylinder 3 and the support inclined beam one 2 are on the same straight line. A placement groove one 31 is provided on one side of the battery fixing cylinder 3. The placement groove one 31 is located at the upper oblique position of the battery fixing cylinder 3. When there is no obstruction outside the placement groove one 31, the battery of the electric bicycle can be placed into the interior of the battery fixing cylinder 3 through the position of the placement groove one 31, so that the battery of the electric bicycle is embedded inside the inclined beam 1 of the electric bicycle, without causing too much impact on the overall structure of the bicycle frame. A number of heat dissipation holes 32 are provided on the other side of the battery fixing cylinder 3. The number of heat dissipation holes 32 is opposite to the position of the placement groove one 31. When the battery is fixed inside the battery fixing cylinder 3, the battery can be dissipated heat through the number of heat dissipation holes 32. And because the number of heat dissipation holes 32 is located at the lower oblique position of the battery fixing cylinder 3, therefore, it can avoid the situation that rainwater enters the interior of the battery fixing cylinder 3 through the heat dissipation holes 32 and damages the battery. One end of the movable cylinder 5 is rotatably connected to the support inclined beam two 4. The inner diameter size of the support inclined beam two 4 matches the outer diameter size of the battery fixing cylinder 3.

When rotating the movable cylinder 5, the position of the movable cylinder 5 will not change. A placement groove two 51 is provided on one side of the movable cylinder 5. The placement groove two 51 matches the size of the placement groove one 31. When the placement groove two 51 rotates to align with the placement groove one 31, the battery can be placed into the interior of the battery fixing cylinder 3 through the placement groove two 51 and the placement groove one 31, and then rotate the movable cylinder 5 by 180 degrees to make the movable cylinder 5 block the placement groove one 31, so that the battery can be enclosed inside the battery fixing cylinder 3.Meanwhile, the second insertion slot 51 will rotate from the upper oblique side of the movable cylinder 5 to the lower oblique side of the movable cylinder 5, and the position of the second insertion slot 51 is aligned with that of a plurality of heat dissipation holes 32, so that there is no obstruction outside the plurality of heat dissipation holes 32, and heat can be dissipated to the outside. The battery of the electric bicycle can be limited by the battery fixing cylinder 3, and the battery can be enclosed inside the battery fixing cylinder 3 by the rotation of the movable cylinder 5, thereby facilitating the installation and removal of the battery of the electric bicycle and improving the convenience of maintenance. The movable cylinder 5 and the battery fixing cylinder 3 will not affect the concealment and protection effect of the battery. At the same time, the battery can be dissipated through the plurality of heat dissipation holes 32, improving the heat dissipation effect of the battery while hiding and fixing the battery, and avoiding the situation that the battery temperature is too high due to the small and relatively enclosed storage space of the battery, which affects the service life.

[0019] A protective pad 311 is provided inside the battery fixing cylinder 3, and the protective pad 311 is located at the bottom of the battery fixing cylinder 3; when the battery is inside the battery fixing cylinder 3, the protective pad 311 will be located between the battery and the bottom of the battery fixing cylinder 3, and the collision between the battery and the battery fixing cylinder 3 can be reduced through the protective pad 311.

[0023] Working principle and usage process of the present utility model: When in use, first, the insertion slot two 51 needs to be rotated to align with the insertion slot one 31. Then, the battery can be placed into the interior of the battery fixing cylinder 3 through the insertion slot two 51 and the insertion slot one 31. Next, the movable cylinder 5 is rotated 180 degrees so that the movable cylinder 5 shields the insertion slot one 31, thereby enclosing the battery inside the battery fixing cylinder 3. The battery is fixed and protected by the battery fixing cylinder 3 and the movable cylinder 5. At the same time, the insertion slot two 51 rotates from the upper oblique side of the movable cylinder 5 to the lower oblique side of the movable cylinder 5, and the position of the insertion slot two 51 aligns with that of several heat dissipation holes 32, making the outside of the several heat dissipation holes 32 unobstructed, so that heat can be dissipated externally, improving the heat dissipation effect of the battery. Moreover, one end opening of the threaded hole 521 aligns with the threaded groove 42, and the movable cylinder 5 can be fixed by connecting the bolt 43 with the threaded groove 42 and the threaded hole 521.
