Description

Spring power-assisted mounting device for automobile trunk

Technical Field

The utility model relates to the technical field of automobile assembly, in particular to an automobile trunk spring power-assisted mounting device.

Background

And the automobile trunk spring is assembled in the automobile rear trunk. Typically two trunk springs per trolley, which together with an air damper rod control the opening and closing of the trunk. The spring has three stable states, namely a free state before assembly, an opened state of the suitcase after installation and a closed state of the suitcase after installation. Because in the product development stage, the suitcase spring parameter is not completely determined, the time and effort of the spring hand tool can be wasted, and the assembly mechanism is designed to achieve the purposes of labor saving and stable installation of the suitcase spring.

At present, a manual T-shaped auxiliary tool direct assembly method is mostly adopted for installing the springs of the automobile trunk. The T-shaped auxiliary tool is provided with a front end hook which is used for hooking the spring hook, and the T-shaped handle is used for holding and directly pulling for assembly. The manual T-shaped auxiliary tool is simple in structure, but does not have a booster device, and as the stretching distance of the spring is increased, the pulling force is gradually increased, so that the working strength of operators is high.

The Chinese patent No. 214420562U discloses an automobile trunk lid gas spring mounting bracket, which comprises a first plate body, a second plate body and a third plate body; the first plate body and the second plate body are fixedly connected to the same horizontal plane; the first plate body is fixedly connected with the third plate body, and an included angle is formed between the first plate body and the third plate body; compared with the prior art, the utility model has the advantages that the two-in-one structural design of the gas spring mounting bracket and the limiting block mounting plate of the trunk cover reduces the development of one part and one set of die, reduces the cost and is convenient for personnel to install and operate. However, as the distance of the spring extension increases, the tension gradually increases, and the working strength of operators is still high.

The device comprises a rotary positioning pin 1, a spring hook 2, a sliding block 3, a sliding rail 4 and a hollow wrench 5; the rotary positioning pin 1 is installed at one end of the sliding rail 4, the sliding block 3 is installed on the sliding rail 4, the spring hook 2 is installed on the sliding block 3, and the other end of the sliding rail 4 is inserted into the hollow wrench 5.

Further, the slider 3 slides on the slide rail 4.

Further, the slide rail 4 slides in the hollow wrench 5.

Further, a limiting pin 6 is installed on the sliding rail 4.

Further, a limit chute 7 is arranged on the hollow wrench 5.

Further, a U-shaped plate 8 is arranged on the sliding block 3.

Further, when the slide rail 4 slides in the hollow wrench 5, the limit pin 6 slides in the limit chute 7.

Further, the U-shaped plate 8 is arranged on the connecting side of the sliding block 3 and the sliding rail 4.

The beneficial effects of the utility model are as follows: the installation of the trunk spring is completed through the relative movement of the sliding rail and the sliding block and the rotary movement of the whole device; the device can rapidly, stably and labor-saving finish the installation of the suitcase spring.
