Detailed Implementation

[0028] like Figures 1 to 8 As shown, the quick-release battery structure of the electric vehicle includes a main frame 1, a mounting cylinder 2, a front fork assembly 3, a rear wheel 4, a tail fork 5, a battery compartment 6, and a front wheel 7.

[0029] Furthermore, the main frame 1 has a triangular frame in its forward projection, including a horizontally arranged main beam frame 11 and an inclined secondary support frame 12, which are fixedly connected by at least one reinforcing tube 13 to form a stable truss structure.

[0030] It also includes at least two reinforcing plates 14, the top of which is fixedly connected to the main beam frame 11 and the bottom of which is fixedly connected to the secondary support 12. The setting of the reinforcing plates 14 makes the fixation between the main beam frame 11 and the secondary support 12 more stable.

[0031] The main beam tube, the secondary bracket 12, and the reinforcing tube 13 are all made of hollow aluminum tubes, making the vehicle body lighter overall, and the three are fixed together by welding.

[0032] Furthermore, the fixed cylinder 2 is located at the front end of the main frame 1, and is fixedly connected to the main beam frame 11 and the auxiliary support 12. The front fork assembly 3 is rotatably provided inside it.

[0033] The front fork assembly 3 includes:

[0034] The riser 31 is rotatably installed inside the fixed cylinder 2;

[0035] The handlebars 32 are fixedly installed on the top of the riser tube 31;

[0036] The shock absorption unit 33 is fixedly installed at the bottom of the riser 31. A support plate 34 is fixedly provided at the bottom of the shock absorption unit 33. The shock absorption unit 33 is used to absorb bumps during driving.

[0037] Furthermore, a rear brake pad 41 is fixedly provided on the rear wheel 4;

[0038] The rear wheel 4 integrates a hub motor 4242, which provides driving force and makes the vehicle body lighter overall.

[0039] Furthermore, the tail fork 5 includes a first support member 51 and a second support member 52. The first support member 51 and the second support member 52 extend rearward to form a rear wheel 4 mounting position for mounting the rear wheel 4. The second support member 52 is provided with a rear wheel locking mechanism 53 controlled by a key 8 for mechanically locking the rear brake pad 41. The rear wheel locking mechanism 53 is used to lock the rear brake pad 41, realizing locking in the non-driving state and increasing the safety of vehicle parking.

[0040] The rear wheel locking mechanism 53 uses a telescopic rod in conjunction with an opening on the rear brake pad 41 to achieve locking;

[0041] The second support member 52 is also provided with a parking rack 5201 and a fixing frame 5202, and the fixing frame 5202 is provided with a foldable foot pedal 5203.

[0042] Furthermore, the battery compartment 6 is fixedly installed on the main beam frame 11, and is equipped with a mechanical locking mechanism controlled by a key 8. It shares a key 8 with the rear wheel locking mechanism 53. The battery 61 is detachably installed inside the battery compartment 6. The battery 61 and the battery compartment 6 are connected by a hot-swappable quick connection method, which increases the speed of battery 61 installation and removal and makes it easier to remove the battery 61 for charging.

[0043] A positioning frame 62 is installed on the battery compartment 6, and a seat 63 is rotatably installed on the positioning frame 62. A concave locking tube 6301 that cooperates with a mechanical locking mechanism is fixedly provided at the bottom of the seat 63.

[0044] The mechanical locking mechanism is a hook integrated on the lever, which works with the concave locking tube 6301 to achieve locking.

[0045] The mechanical locking mechanism and the rear wheel locking mechanism 53 share the same key 8 for control, reducing the number of keys 8 that users need to carry.

[0046] Insert key 8 and rotate it 90° counterclockwise to release the rear wheel locking mechanism 53;

[0047] Remove key 8 and reinsert it into the keyhole on the battery compartment, then rotate key 8 to 180° to unlock the battery compartment.

[0048] Reversing the above operations will achieve the locking effect.

[0049] Furthermore, the front wheel 7 is rotatably mounted on the support plate 34, and a front brake pad 71 is fixedly mounted on the front wheel 7.

[0050] Both the front brake pad 71 and the rear brake pad 41 are equipped with hydraulic cable disc brakes that control their stopping, which are controlled by grips integrated on the handlebars 32.
