DETAILED DESCRIPTION

[0019] A frame body with a battery box taken out from the side, the structural schematic diagram of which is as follows Figures 1 to 4As shown, it includes a frame head pipe 1, a frame middle pipe 3, a frame tail pipe 4 and a battery box 5 which are fixedly connected in sequence. The frame head pipe, the frame middle pipe and the frame tail pipe can be made separately from each other and then fixedly connected by welding.

[0020] The frame head pipe, frame middle pipe and frame tail pipe are all hollow structures interconnected, and the frame head pipe and frame tail pipe are bent arc structures, which not only have beautiful appearance, but also can be replaced according to the needs of different vehicle models without changing the shape of the frame middle pipe.

[0021] A battery box side access port 6 is provided on the side of the middle part of the frame middle tube, an upper frame fixing cover 11 is fixedly installed above the battery box side access port in the frame middle tube, the upper frame fixing cover and the frame middle tube can be fixedly connected by screws, a lower frame fixing cover 7 is fixedly installed below the battery box side access port in the frame middle tube, the lower frame fixing cover and the frame middle tube can also be fixedly connected by screws, and disassembly and assembly are convenient and quick. The battery box is installed between the upper frame fixing cover and the lower frame fixing cover from the battery box side access port.

[0022] The side-mounted battery box has a relatively large space capacity, and there is no need to consider the problem of avoiding the problem of taking out the battery box. Compared with the upper or lower-mounted battery box method, the battery box is more convenient and quick to install and remove.

[0023] Optimized, the frame middle tube is provided with reinforcing supports 16 on both upper and lower sides of the battery box side access port, and the reinforcing supports can be integrally formed with the frame middle tube, making the production more convenient and quick, and the structure more reliable, which can prevent the frame from being twisted and deformed due to welding and heat treatment, and enhance the strength of the frame.

[0024] Furthermore, the lower frame fixing cover is fixedly provided with a lower frame fixing cover limiting groove 8 and a lower frame fixing cover electrode contact 9. The lower frame fixing cover limiting groove and the lower frame fixing cover can be integrally formed, with a simple manufacturing process and a reliable structure, and two can be provided to play a better limiting role and enhance the reliability of the battery box installation. A battery lock 2 is installed on the frame middle tube, and the battery lock and the frame middle tube can be fixedly connected by screws. The battery lock is provided with a lock tongue 10, and a lock tongue clearance hole 12 is provided on the upper frame fixing cover, and a spring column mounting sleeve 14 is fixedly provided on the upper frame fixing cover, and a spring column 15 is installed in the spring column mounting sleeve. The spring column mounting sleeve can be integrally formed with the upper frame fixing cover, with a simple manufacturing process and a reliable structure.

[0025] The battery box includes a battery box top cover 23, a battery box tube 17, and a battery box tail cover 20 that are fixedly connected in sequence. The battery box tail cover is provided with a battery box tail cover limit protrusion 18 and a battery box electrode contact 19 that matches the electrode contact of the lower frame fixed cover. The battery box top cover is provided with a lock tongue groove 24 and a spring post groove 26, and both the lock tongue groove and the spring post groove can be integrally formed with the battery box top cover.

[0026] When specifically installing the frame, first weld the frame head tube, the frame middle tube, and the frame tail in sequence. Then install a lock on the upper part of the frame middle tube, and then install the upper frame fixed cover. Before installing the upper frame fixed cover, first install the spring post into the spring post installation sleeve, and then use screws to fixedly install the upper frame fixed cover in the frame middle tube. Finally, use screws to fixedly install the lower frame fixed cover in the lower part of the frame middle tube.

[0027] When inserting the battery box into the frame middle tube, first place the battery box tail into the tail of the frame middle tube. The battery box tail cover limit protrusion corresponds to the lower frame fixed cover limit groove, and the lower frame fixed cover electrode contact corresponds to the battery box electrode contact. Then, during the process of pushing forcefully, as the battery box gradually enters the frame middle tube, the lock tongue passes through the lock tongue relief hole and rubs against the lock tongue groove on the battery box top cover. When the battery box completely enters the frame middle tube, the lock tongue is completely snapped into the lock tongue groove, achieving the fixed clamping of the battery box. At this time, the spring post is compressed into the spring post groove on the battery box top cover. When the lock is opened with a key, the lock tongue retracts and separates from the lock tongue groove, and the battery box directly pops out under the restoring force of the spring post, realizing the opening of the battery box.

[0028] Two spring posts can be provided here to improve the reliability of the battery box opening.

[0029] Optimally, the lower part of the lower frame fixed cover limit groove is of an inclined structure, and the battery box tail cover limit protrusion matches the lower frame fixed cover limit groove, which is convenient for limiting the battery box and pushing it in and taking it out.

[0030] Optimally, the end of the lock tongue is of an inclined structure, and the lock tongue groove matches the shape of the lock tongue, which is convenient for pushing the battery box in and taking it out.

[0031] Furthermore, a battery box head waterproof ring 27 is installed between the battery box top cover and the battery box tube, and a battery box tail waterproof ring 21 is installed between the battery box tail cover and the battery box tube. The installation of the battery box head waterproof ring and the battery box tail waterproof ring can prevent water from entering the battery box.

[0032] Furthermore, a plurality of battery box tube brackets 22 are provided inside the battery box tube. The battery box tube brackets are tubular structures. The core can pass through the battery box tube brackets, and they can play a role in supporting the battery box tube, thereby enhancing the strength of the battery box tube and the vehicle frame. Specifically, the plurality of battery box tube brackets can be connected by clamping, or can be directly and closely arranged inside the battery box tube.

[0033] When specifically assembling the battery box, the core can first be inserted into the battery box bracket, then the battery box bracket can be installed into the battery box tube, then the battery box head waterproof ring can be installed, then the battery box tail waterproof ring can be installed, and finally the battery box top cover and the battery box tail cover can be installed, and the battery box top cover, the battery box head waterproof ring and the battery box tube can be fixedly installed with screws, and the battery box tail cover, the battery box tail waterproof ring and the battery box tube can be fixedly installed with screws.

[0034] Furthermore, a guide block 13 is provided on the upper vehicle frame fixing cover, and a guide groove 25 is fixedly provided on the battery box top cover. The guide block moves along the guide groove, which can further facilitate the installation of the battery box and prevent the battery box from deviating during the installation process.

[0035] In summary, the vehicle frame main body with a side-taking battery box provided by the present application can freely replace the vehicle frame head tube and the vehicle frame tail tube according to the vehicle model requirements. By adopting the side-taking battery box method, the space capacity is larger and the battery box can be taken out and installed conveniently and reliably.
