DETAILED DESCRIPTION

[0028] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-Figure 10 As shown, a battery box lock structure of a mobility scooter comprises a seat bracket 1 and a battery box 2 mounted on the seat bracket 1, a vehicle bracket 3 is provided below the seat bracket 1, a safety lock 4 connected to the vehicle bracket 3 is installed on the battery box 2; the safety lock 4 comprises a lock body 41 and a lock tongue 42 that can rotate around the lock body 41, a locking notch 31 that is locked with the lock tongue 42 is formed on the vehicle bracket 3; a connecting seat 23 connected to the vehicle bracket 3 is formed at the bottom of the battery box 2.

[0030] The battery box 2 and the vehicle bracket 3 are respectively arranged on the upper and lower sides of the seat bracket 1, and the battery box 2 and the vehicle bracket 3 are connected by a safety lock 4. Under the action of the safety lock 4, the battery box 2 installed on the seat bracket 1 is locked with the vehicle bracket 3, thereby achieving stability and safety of the battery box 2.

[0031] At the same time, the connecting seat 23 is arranged at the bottom of the battery box 2 , and the connection between the bottom of the battery box 2 and the vehicle bracket 3 is achieved under the action of the connecting seat 23 .

[0032] The battery box 2 is formed with a mounting hole 21 for mounting the lock body 41 . The lock tongue 42 passes through the seat bracket 1 and is connected to the vehicle bracket 3 . The mounting hole 21 is arranged along the length direction of the seat bracket 1 .

[0033] A positioning seat 22 is formed at the bottom of the battery box 2 and is relatively arranged on both sides of the safety lock 4. A positioning cavity 11 for loading the positioning seat 22 is formed on the seat bracket 1. The positioning seat 22 is snapped into the positioning cavity 11, thereby realizing the positioning connection between the bottom of the battery box 2 and the seat bracket 1. At the same time, the safety lock 4 is set between the positioning seats 22 on the opposite sides to realize the locking between the two relatively arranged positioning seats 22 to ensure the overall stability.

[0034] The positioning cavity 11 is a sunken structure located at the bottom of the seat bracket 1. The connecting seat 23 and the vehicle bracket 3 are both located between the relatively arranged positioning seats 22, and the connecting seat 23 is arranged corresponding to the middle of the battery box 2. Through the setting of the positioning cavity 11 with a sunken structure, the horizontal movement direction of the vehicle bracket 3 is limited to ensure the connection stability between the vehicle bracket 3 and the seat bracket 1.

[0035] A positioning protrusion 12 for installing a connecting seat 23 is formed on the seat bracket 1. The connecting seat 23 is inserted into the positioning protrusion 12. The positioning protrusion 12 is used to locate the position of the connecting seat 23. The setting of the positioning protrusion 12 and the positioning cavity 11 ensures that the battery box 2 is stably set on the seat bracket 1.

[0036] At least two connecting posts 24 for connecting to the vehicle bracket 3 and a plurality of conductive posts 25 for powering are formed on the connecting base 23. The connecting posts 24 are plugged into the vehicle bracket 3, thereby achieving a stable connection with the vehicle bracket 3 under the action of the connecting base 24. The conductive posts 25 can be connected to the pins on the vehicle bracket 3, thereby receiving the power of the battery box 2 through the pins.

[0037] The vehicle bracket 3 is also formed with a reserved groove 13 for facilitating the rotation of the locking tongue 42. Under the action of the reserved groove 13, the locking tongue 42 rotates, thereby passing through the seat bracket 1 and being connected to the vehicle bracket 3 with the locking tongue 42.

[0038] The locking notch 31 is communicated with the reserved groove 13, and a card interface 43 is formed on the lock tongue 42 to be engaged with the locking notch 31. When the lock tongue 42 is rotated to a vertical position, the lock tongue 42 is rotated to the locking notch 31 through the reserved groove 13, and the card interface 43 abuts against the locking notch 31 to realize the engagement between the lock tongue 42 and the vehicle bracket 3.

[0039] A battery slot 15 for installing a battery box 2 is formed on the seat bracket 1. The battery slot 15 is placed with the battery box 2. The battery slot 15 is connected to the positioning seat 22. The seat bracket 1 is also clamped with the opposite sides of the battery box 2. A seat 14 is formed on the seat bracket 1, and the battery slot 15 is connected to the rear end of the seat 14.

[0040] In actual use, the lock tongue 42 of the safety lock 4 can be rotated 90° by a key. By opening a mounting hole 21 on the battery box 2, the safety lock 4 is installed on the battery box 2, and the angle of the rotating tongue 42 is controlled by a key to achieve the locking and release of the battery box 2. The battery box 2, the seat bracket 1 and the vehicle bracket 3 are combined together, which can not only protect the battery box 2 and prevent it from being lost, but also fix the battery box 2 to prevent the battery in the battery box 2 from shaking and falling off during operation.
