Electric tricycles are widely used in cities and rural areas due to their strong applicability, flexibility, simple maintenance, easy repair, low price, and the ability to flexibly travel on narrow roads, rural roads, and field paths in urban communities and rural areas. When producing electric tricycles, in order to accommodate the use scenarios in which the vehicle often travels through narrow paths and for safety considerations, anti-collision protection brackets are installed on both sides of the front windshield of the vehicle.

The root of the cross bar clamping arm 51 is slidably installed on the adjusting slide rail 57 and can be fixed at any position on the adjusting slide rail 57 by bolts installed in the adjusting hole 58. The position of the cross bar clamping arm 51 on the adjusting slide rail 57 is adjusted by sliding. After the adjustment is completed, the cross bar clamping arm 51 is clamped and fixed in the adjusting hole 58 by bolts located on both sides of the cross bar clamping arm 51, so as to achieve the purpose of clamping any position on the cross bars 3 of different lengths, so as to leave enough space for welding.

[0039] In this embodiment, the cross bar welding structure 5 also includes a cylinder 53, an inclined guide rail 54 and a connecting bracket 55. The cylinder 53 is installed in a base 56. The cylinder 53 is obliquely arranged and is at an angle of 45° to the horizontal plane. The output shaft of the cylinder 53 is connected to the lower inclined surface of the connecting bracket 55. The inclined guide rail 54 is symmetrically arranged at both ends of the connecting bracket 55 and is slidably connected to the connecting bracket 55. The extrusion arm 52 is fixed at both ends of the connecting bracket 55.

During the process of the short rod 4 rotating and plugging into the frame 2, the squeezing sheet 522 can squeeze the short rod 4 into the position inside the frame 2. On the one hand, it can reduce the influence of burrs on the plugging during the cutting process of the short rod 4, and on the other hand, it also reduces the diameter at this position, which is more convenient for the plugging of the short rod 4.

[0042] In this embodiment, the accessory welding structure 6 includes a motor 61, a small pulley 62, a large pulley 63, a transmission gear 64, a mounting bracket 65 and a support seat 66. The motor 61 is installed in the support seat 66. The small pulley 62 is installed on the output shaft of the motor 61 and is connected to the large pulley 63 through a belt. The large pulley 63 and the transmission gear 64 are both installed on a mounting shaft 67 and installed in the mounting bracket 65 through the mounting shaft 67. The mounting bracket 65 is fixed to the upper end of the support seat 66. A dual-purpose clamping device 68 is provided on the mounting shaft 67 and outside the transmission gear 64. The dual-purpose clamping device 68 includes two upper and lower groups and is used to clamp the short rod 4 and the protective ball head 7. The upper and lower groups of dual-purpose clamping devices 68 are driven to rotate by the transmission action of the transmission gear 64. The dual-purpose clamping device 68 clamping the short rod 4 or the protective ball head 7 is driven to rotate by the motor 61, and the rotating short rod 4 or the protective ball head 7 can be more conveniently inserted into the frame 2 and the short rod 4.

[0043] In this embodiment, the dual-purpose clamping device 68 includes a clamping block 681 and a clamping seat 682. The clamping seat 682 is provided with four blocks. The clamping block 681 is fixed to the inner surface of the clamping seat 32. The top surface of the clamping seat 682 is provided with a hanging platform 683. The hanging platform 683 is installed on the mounting plate 685 through a guide hole 684. The inner side surface of the hanging platform 683 is provided with an electric push rod 686. The electric push rod 686 is fixed on the top surface of the mounting plate 685. A protective cover 687 is provided below the mounting plate 685. The protective cover 687 is connected to the mounting shaft 67 through a connecting shaft 688.

[0044] The protective cover 687 is provided with a through hole 6871, and the clamping block 681 can pass through the through hole 6871 and be inserted into the protective cover 687; when the clamping block 681 passes through the through hole 6871, it can tightly clamp the short rod 4, which has a smaller diameter than the protective ball head 7, through the short rod clamping surface 6812; at the same time, a soft cushion is provided at the mouth of the protective cover 687, and the protective ball head 7 inserted into the protective cover 687 can be clamped through the squeezing effect of the soft cushion, and the inserted protective ball head 7 moves into the protective cover 687 until it hits the arc clamping surface 6811 and stops. At this time, the protective ball head 7 is in a state that is convenient for being sleeved on the short rod 4 and convenient for welding after the sleeve connection.

[0045] The top of the pressing block 681 is provided with an arc clamping surface 6811 , and the bottom surface of the pressing block 681 is a short rod clamping surface 6812 .

[0046] In this embodiment, a slide seat 81 is provided on the slide rail 8. The slide seat 81 can slide freely on the slide rail 8, and the slide rail 8 drives the short rod 4 or the protective ball head 7 clamped by the dual-purpose clamping device 68 to move forward.

[0047] Working principle: when in use, first place the cross bar 3 into the cross bar clamping arm 51 which is driven by the cylinder 515 to descend to the appropriate position, the cross bar clamping arm 51 rises, the oil cylinder 53 drives the connecting bracket 55 and the squeezing arm 52 to move backward, so that the frame 2 can be placed at the designated position on the frame placement plate 1, and then the cylinder 515 drives the clamping claw 512 and the clamped cross bar 3 to move downward until the cross bar 3 is placed at the corresponding position on the frame 2, first weld the cross bar 3, the welding here can be manual welding or mechanical arm welding attached to the frame (not shown in the figure), then place the short rod 4 into the dual-purpose clamping device 68 on the lower layer, drive the pressing block 681 to clamp the short rod 4 through the electric push rod 686, and then drive the short rod 4 to start rotating through the motor 61 and slide on the rail. 8 moves toward the frame 2. During the movement, the extrusion sheet 522 is first pushed by the oil cylinder 53 to the position where the mouth of the short rod 4 will reach and ensure that the inner wall of the extrusion sheet 522 is close to the frame 2. When the short rod 4 passes through, the extrusion sheet 522 first spins the part of the short rod 4 inserted into the frame 2. This can reduce the influence of burrs on the insertion during the cutting process of the short rod 4 on the insertion, and reduce the diameter at this position, which is more convenient for the insertion of the short rod 4. After the insertion is completed, the short rod 4 is welded to the frame 2, and then the protective ball heads 7 are respectively placed in the dual-purpose clamping devices 68 of the upper and lower layers, and the rotating protective ball heads 7 are respectively sleeved on the outer ends of the cross bar 3 and the short rod 4. After the sleeve is completed, the protective ball heads 7 are welded and fixed to complete the welding of the anti-collision bracket.

[0048] Based on the above, the invention can quickly position and move the cross bar to the specified position through the cross bar welding structure, so as to help the cross bar to be quickly welded to the frame; the extrusion arm is set to cooperate with the rotating accessory welding structure to spin the end of the short rod to be inserted into the frame, so as to help the short rod to be quickly inserted into the positioning groove on the frame; because the dual-purpose clamping device rotates to move the short rod and the protective ball head forward, the process of inserting the short rod into the frame and the protective ball head into the short rod can be completed quickly, thereby improving the efficiency of welding.
