Description

TECHNICAL FIELD

[0001] The utility model belongs to the electric bicycle manufacturing field especially, and it relates to a cover plate and a turnover switch at the on-line position of an electric bicycle assembly line. BACKGROUND

[0002] In the electric bicycle manufacturing industry, the efficiency of the assembly line and the operational convenience of the employees are directly related to the production quality and cost of the products. However, the design of the on-line position of the conventional assembly line has some obvious problems, which not only affect the smoothness of the production line, but also increase the labor intensity of the employees, and even cause unnecessary damage to the vehicle parts.

[0003] Firstly, the slope design of the cover plate at the on-line position of the conventional assembly line is unreasonable, with a steep slope (up to 40 degrees) and a high height (7.5 cm) of the cover plate from the assembly line. Such design requires the employees to exert a lot of physical effort to lift and turn the entire vehicle when turning the vehicle over to the on-line position, which not only increases the fatigue intensity of the employees, but also may cause damage to the vehicle or injury to the employees due to improper operation.

[0004] Secondly, for some specific vehicle models such as C20, C26, and Mi Du Du, the rear mudguards are installed during the inverted process. When turning the vehicle over to the on-line position, the rear mudguards of these vehicle models often come into contact with the cover plate slope first. Due to the steep slope and high height, the rear mudguards are easily damaged, with a damage rate of up to 5%-10%. This not only increases the manufacturing cost, but also may affect the appearance and performance of the vehicle. In addition, for some vehicle models with rear bars, directly turning the frame may cause scratches on the rear bars. Although measures such as padding with leather pads have been taken, the effect is not ideal, affecting the appearance and requiring frequent replacement of the leather pads, increasing the maintenance cost.

[0005] Furthermore, the conventional foot switch operation method also has some shortcomings. After turning the vehicle over, the employees need to check the position of the foot switch and step on it to return the inverted turret to its normal position and make it operate normally. However, stepping on the foot switch while turning the vehicle over requires the employees to divide their attention to find the switch position and step on it, which causes the turret to be delayed for 2-3 seconds, so that the subsequent front fork post needs to wait for the vehicle to be placed by the on-line post before performing the front fork operation. This waiting operation not only reduces the production efficiency, but also increases the labor intensity of the employees.

[0006] In addition, the foot switch is used very frequently, with an average of thousands of steps per day. In emergency situations such as line drop, the employees may step on it more forcefully, which accelerates the life decay of the foot switch. Therefore, the foot switch needs to be replaced frequently, increasing the equipment maintenance and replacement costs.

[0007] In summary, the conventional dress pipeline on line design has many deficiencies, and needs to be improved and optimized. Utility model content
