[0017] Combination Figures 1 to 2 As shown in the figure, the utility model provides a fixing structure for a quick-change battery compartment, which includes a main structure 1 of the quick-change battery compartment, a first-level guide seat guiding structure 2, a second-level guide post precise guiding structure 3, and a third-level flexible precise docking structure 4. The first-level guide seat guiding structure 2, the second-level guide post precise guiding structure 3, and the third-level flexible precise docking structure 4 are arranged on the vehicle frame. After being positioned through the first-level guide seat guiding structure 2, the second-level guide post precise guiding structure 3, and the third-level flexible precise docking structure 4, the main structure 1 of the quick-change battery compartment is tightly connected to the vehicle frame.

[0018] The first-level guide seat guiding structure 2 is arranged below the main structure 1 of the quick-change battery compartment. The top of the first-level guide seat guiding structure 2 adopts a slope design, which can quickly locate when docking with the main structure 1 of the quick-change battery compartment.

[0019] The second-level guide post precise guiding structure 3 adopts a guide post structure. The second-level guide post precise guiding structure 3 and the first-level guide seat guiding structure 2 form a cooperative relationship to dock with the main structure 1 of the quick-change battery compartment.

[0020] The third-level flexible precise docking structure 4 includes a quick-change electrical interface connecting plate 41 and an elastic support 42. The elastic support 42 connects the quick-change electrical interface connecting plate 41 to the vehicle frame, and the quick-change electrical interface connecting plate 41 can be tightly connected to the quick-change electrical interface of the quick-change battery compartment. Embodiment

[0021] On the basis of the above-mentioned first embodiment, a pin ear structure 5 is provided on the main structure 1 of the quick-change battery compartment, and a vehicle frame fixed hanging plate structure 6 is provided on the vehicle frame. The main structure 1 of the quick-change battery compartment is clamped to the vehicle frame fixed hanging plate structure 6 through the pin ear structures 5 on both sides of the main body.

[0022] A protrusion 51 is provided at the end of the pin ear structure 5. The protrusion 51 cooperates with the vehicle frame fixed hanging plate structure 6 to limit the forward and backward movement of the main structure 1 of the quick-change battery compartment.

[0023] After being positioned through the first-level guide seat guiding structure 2, the second-level guide post precise guiding structure 3, and the third-level flexible precise docking structure 4, this structure enables the quick-change plug to be smoothly docked. Through the mutual cooperation of the battery compartment pin ear structure 5 and the vehicle frame fixed hanging plate structure 6, the groove depth of the vehicle frame fixed hanging plate structure 6 is relatively deep, preventing the battery compartment from jumping out of the vehicle frame fixed hanging plate structure 6 under extreme road conditions; there is a small amount of interference between the pin ear structure 5 and the two sides of the groove of the vehicle frame fixed hanging plate structure 6, generating a certain amount of friction. When the vehicle makes a sharp turn, it prevents the battery from tipping over due to the inertia of the battery compartment. The appropriate friction generated ensures that the battery compartment does not jump upward during the operation of the equipment, and the pin ear structure 5 and the vehicle frame fixed hanging plate structure 6 can effectively be constrained.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
