Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] Reference Figure 1-4 The utility model provides a technical solution: a battery connection structure of a flywheel electric starter, comprising a connection shell 1, a motor 2 is installed on the right side of the connection shell 1, a battery lock 3 is installed on the top of the connection shell 1, a portable battery pack 4 is hinged on the top of the connection shell 1 through the battery lock 3, a battery is installed in the inner cavity of the portable battery pack 4, an insulating block 5 is installed on the top of the motor 2, a power-taking pin 6 is installed on the top of the insulating block 5, the power-taking pin 6 includes a contact spring 601 and a contact point 602, by providing the portable battery pack 4, since the portable battery pack 4 is installed with a battery inside, after the portable battery pack 4 is rotated, the battery contacts the power-taking pin 6, and through the cooperation of the contact spring 601 and the contact point 602, the battery is electrically connected to the motor 2 through the power-taking pin 6, providing driving force to the motor 2;
[0023] Reference Figure 1-4 A battery buckle unlocking switch 7 is installed on the right side of the portable battery pack 4. The right side of the battery buckle unlocking switch 7 is flush with the right side of the portable battery pack 4 in the vertical direction. By setting the battery buckle unlocking switch 7, after the battery buckle unlocking switch 7 is opened, the inner cavity of the portable battery pack 4 is exposed, so that the staff can take out the internal battery for replacement. Moreover, since the right side of the battery buckle unlocking switch 7 is flush with the right side of the portable battery pack 4 in the vertical direction, when the portable battery pack 4 is rotated, the battery buckle unlocking switch 7 and the battery buckle bracket 8 will not collide;
[0024] Reference Figure 1-4A battery buckle bracket 8 is installed on the right side of the motor 2, and a notch 9 is opened at the bottom of the portable battery pack 4.

[0026] Reference Figure 1-4 A start switch 13 and a display screen 14 are provided on the top of the portable battery pack 4. By providing the start switch 13 and the display screen 14, the staff can control the switch of the battery through the start switch 13, thereby indirectly controlling the drive of the motor 2. The display screen 14 can display the current status of the battery, so that the staff can intuitively understand the status of the battery.
[0027] Specifically, the working process or working principle of the battery connection structure of the flywheel electric starter is as follows: when in use, after the portable battery pack 4 is rotated, the battery contacts the power-taking foot 6, and through the cooperation of the contact spring 601 and the contact point 602, the battery is electrically connected to the motor 2 through the power-taking foot 6, providing driving force to the motor 2. When the portable battery pack 4 is rotated, the positioning wedge 11 is squeezed by the battery buckle bracket 8, so that the positioning wedge 11 is retracted into the inside of the battery buckle bracket 8, until the portable battery pack 4 is rotated to the preset position, the positioning wedge 11 pops out and is snapped into the inside of the positioning slot 10. At this time, the bottom of the portable battery pack 4 The position of the notch 9 contacts the top of the battery buckle bracket 8, providing support for the portable battery pack 4, thereby limiting the portable battery pack 4. Since the shock-absorbing rubber pad 12 is located at the top of the connecting shell 1, when the portable battery pack 4 rotates, it will contact the top of the shock-absorbing rubber pad 12 to reduce the shock of the portable battery pack 4 and prevent the portable battery pack 4 from colliding with the surface of the connecting shell 1 when rotating. The staff can control the battery switch by starting the switch 13, thereby indirectly controlling the drive of the motor 2. The display screen 14 can display the current status of the battery, so that the staff can have an intuitive understanding of the battery status.
