[0023] like Figures 1 to 3 As shown, a quick-disassembly vehicle-mounted battery 10 of the present application includes: a first connector 11, a second connector 12 and a battery 13. During installation, the first connector 11 is fixed to the chassis 14 of the vehicle body, and the second connector 12 is fixed to the housing of the battery 13. When the battery 13 is installed on the chassis 14, the first connector 11 is plugged into the second connector 12 to achieve electrical connection. The chassis 14 is formed with a guide edge 142, and the housing of the battery 13 is formed with a guide recess 132 for matching the guide edge 142 to guide the insertion and installation of the battery 13, and the housing of the battery 13 is fixed to the chassis 14 by a fixing ear 133. That is, when installing the battery 13, the guide edge 142 is inserted into the guide recess 132, and the battery 13 is pushed to the installation position along the guide edge 142. At this time, the first connector 11 and the second connector 12 are electrically plugged, and then the fixing ear 133 is fixed to the chassis 14 by screws, thereby achieving the installation and fixation of the battery 13. When the battery 13 needs to be removed, the screws on the fixing ears 133 are removed, and the battery 13 is pulled out by moving along the guide edge 142 .

[0024] The above-mentioned quick-detachable vehicle battery 10 is electrically connected through the first connector 11 and the second connector 12. The connection is fast and the electrical structure is stable. Through the cooperation of the fixing ear 133 and the guide recess 132, not only can the battery 13 be installed in a limited position to improve the installation speed, but the limiting effect of the fixing ear 133 and the guide recess 132 can ensure the stability of the installation structure of the battery 13, and the battery 13 can also be quickly and stably disassembled in one direction to avoid affecting the first connector 11 and the second connector 12 during disassembly.

[0025] As a specific embodiment, the chassis 14 is provided with a limiting protrusion 141 for limiting the installation of the battery 13. The housing of the battery 13 is formed with a snap-fitting recess 131 for matching the shape of the limiting protrusion 141 to be limitedly installed on the chassis 14. When the battery 13 is limitedly engaged with the limiting protrusion through the snap-fitting recess 131, the second connector 12 is guided to be plugged into the first connector 11. Such a limiting installation structure can limit the travel of the battery 13, thereby preventing the movement inertia of the battery 13 from causing impact on the first connector 11 and the second connector 12.

[0026] As a specific implementation, the first joint 11 is provided with a pin hole 111, and the second joint 12 is provided with a guide pin 121 for inserting the pin hole 111 to accurately connect the first joint 11 and the second joint 12, and the installation accuracy is higher. Specifically, the first joint 11 is provided with two pin holes 111, and the second joint 12 is provided with two guide pins 121. The two pin holes 111 and the two guide pins 121 are distributed in the horizontal direction, so that the relative rotation of the first joint 11 and the second joint 12 after the connection can be limited in the horizontal direction. The side of the guide pin is formed with a convex strip 1211, and the pin hole is formed with a slot 1111 for matching the convex strip, so that the resistance of the plug-in is increased, thereby further improving the stability of the connection between the first joint 11 and the second joint 12.

[0027] As a specific implementation, the second connector 12 is provided with an electrode metal ring 122, and the first connector 11 is provided with an electrode metal column 112 for inserting the electrode metal ring 122, so as to achieve electrical connection. The end of the electrode metal column 112 away from the second connector 12 is a round head, which has a guiding function during plugging and can also avoid collision during plugging. Specifically, the second connector 12 is provided with two electrode metal rings 122, and the first connector 11 is provided with two electrode metal columns 112. The two electrode metal rings 122 and the two electrode metal columns 112 are distributed in the vertical direction, so that the relative rotation of the first connector 11 and the second connector 12 after docking can be limited in the vertical direction.

[0028] In the above solution, a cross plug-in structure is formed by two horizontal guide pins 121 and two vertical electrode metal pillars 112 , which can improve the plug-in stability of the first connector 11 and the second connector 12 .

[0029] As a specific implementation, the second connector 12 is provided with a communication hole 123, and the first connector 11 is provided with a communication pin 113 for being electrically plugged into the communication hole 123 to achieve electrical connection between the battery 13 and the controller of the vehicle body.

[0030] As a specific implementation, the first connector 11 is detachably mounted on the chassis 14 by screws, and the second connector 12 is detachably mounted on the housing of the battery 13 by screws, so that it is easy to replace and repair the first connector 11 or the second connector 12 when problems such as loose connection occur.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
