[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] A battery bead structure for an electric vehicle frame, such as Figures 1 to 5 As shown, it includes a beading body 1, and both ends of the beading body 1 are integrally provided with a mounting portion 2. The mounting portion 2 is provided with a positioning groove 3 for the frame side tube to pass through, and the positioning groove 3 is adapted to the frame side tube. The positioning groove 3 restricts the frame side tube so that the frame side tube and the beading body 1 remain relatively stable. Furthermore, the opening of the positioning groove 3 is vertically downward. Under the action of gravity, the frame side tube is ensured to be stably maintained in the positioning groove 3, thereby further improving the stability of the structure.

[0023] A limiting groove 6 is provided on the inner wall of the positioning groove 1 3, and the limiting groove 6 is for inserting the reinforcing protrusion 7 on the frame side tube. The length direction of the reinforcing protrusion 7 is relatively perpendicular to the length direction of the frame side tube. The limiting groove 6 is adapted to the reinforcing protrusion 7. The reinforcing protrusion 7 is provided on the frame side tube to enhance its structural strength. Moreover, the limiting groove 6 restricts the reinforcing protrusion 7, thereby further ensuring the relative stability of the frame side tube and the pressure strip body 1.

[0024] The mounting portion 2 is detachably connected to a positioning member 4. Specifically, the mounting portion 2 is threadedly connected to a fastener 8, which passes through the positioning member 4. The fastener 8 can press the positioning member 4 onto the mounting portion 2, thereby achieving a firm connection between the mounting portion 2 and the positioning member 4. The fastener 8 is preferably a bolt.

[0025] The positioning member 4 is provided with a through hole 9 for the fastener 8 to pass through, and the fastener 8 is rotatably matched with the through hole 9 , that is, the positioning member 4 can rotate with the fastener 8 as the axis.

[0026] At least two positioning grooves 2 5 are provided on the positioning member 4 in the horizontal direction for the frame side tube to pass through. The two positioning grooves 2 5 are adapted to the frame side tube, and the openings of the two positioning grooves 2 5 face opposite directions. The two positioning grooves 2 5 cooperate to restrict the frame side tube from two opposite horizontal directions, thereby limiting the separation of the frame side tube from the pressure strip body 1.

[0027] It should be noted that when installing the positioning member 4, since the openings of the two positioning grooves 2 5 are facing opposite directions, the positioning member 4 must be placed at an angle first, and then the positioning member 4 is rotated so that the frame side tube enters the positioning groove 2 5 from the openings of the two positioning grooves 2 5. The positioning member 4 can rotate with the fastener 8 as the axis, which can effectively improve the stability of the positioning member 4 during rotation.

[0028] At least two limiting members 10 are detachably connected to the positioning member 4, and the two limiting members 10 correspond to the two positioning grooves 2 5 respectively. Specifically, the two limiting members 10 are both threadedly connected to the positioning member 4. The limiting members 10 are used to limit the frame side tube from detaching from the opening of the positioning groove 2 5. Specifically, the two limiting members 10 can respectively block the opening of the two positioning grooves 2 5. The limiting effect of the limiting members 10 on the frame side tube can improve the stability and reliability of the structure.

[0029] A positioning protrusion 11 is provided on the upper surface of the mounting portion 2, and a positioning groove 12 is provided on the lower surface of the positioning member 4. The positioning protrusion 11 is adapted to the positioning groove 12, and the positioning protrusion 11 can be inserted into the positioning groove 12 respectively. Through the cooperation between the positioning groove 12 and the positioning protrusion 11, the relative stability of the positioning member 4 and the mounting portion 2 can be further improved.

[0030] It should be noted that there is no need to drill holes on the frame side tube to connect with the fasteners 8. The frame side tube can be restricted by cooperating with the positioning groove 1 3, the two positioning grooves 2 5 and the limit groove 6 with the reinforcing protrusion 7 on the frame side tube. This can keep the pressure strip body 1 and the frame side tube relatively fixed, avoiding the adverse effect of drilling on the structural strength of the electric vehicle frame side tube, and ensuring the reliability and safety of the electric vehicle frame.

[0031] The installation method of this utility model is as follows:

[0032] First, align the limiting groove 6 with the reinforcing protrusion 7 on the frame side tube, and then move the pressure strip body 1 so that the frame side tube enters the positioning groove 1 3 from the opening of the positioning groove 1 3. At this time, the reinforcing protrusion 7 on the frame side tube is inserted into the limiting groove 6. The next step is to pass the fastener 8 through the through hole 9 on the positioning member 4 and threadedly connect it to the mounting part 2. Then, push the positioning member 4 to rotate with the fastener 8 as the axis, so that the frame side tube enters the positioning groove 2 5 from the opening of the two positioning grooves 2 5. Then, continue to rotate the fastener 8 to press the positioning member 4 onto the mounting part 2 through the fastener 8. At this time, the positioning protrusion 11 on the upper surface of the mounting part 2 is inserted into the positioning groove 12 on the lower surface of the positioning member 4. Finally, install the two limiting members 10 on the positioning member 4, and the two limiting members 10 respectively block the openings of the two positioning grooves 2 5.
