Problems solved by technology

[0002] With the development trend of automobile intelligence and networking, the number of electronic products carried by vehicles is increasing, and electric tailgates are becoming more and more common. The opening and closing of electric tailgates are realized by electric struts. Further, in order to ensure the When in use, it can be in the hovering state, which is realized by the damper. The damper provides the damping torque for the screw, increases the internal resistance of the strut, ensures a good hovering effect, and can effectively prevent the tailgate from switching between the open state and the closed state. At present, the damper of the electric tailgate mostly adopts the structure of damping plate and spring. When assembling the damper, it is necessary to put multiple positioning plates, friction plates, and transmission ring gears into the damper shell in sequence. Due to the small space in the shell and the deep cavity, it is difficult to realize assembly automation in this process. Correspondingly, after the above three types of sheets are loaded into the damper housing in sequence, it is difficult to detect whether the stacking order of the sheets is correct or not

Embodiment 1

[0027] Such as figure 1 As shown, the strut damper mainly includes a damper shell 100, a damper tray 200, a damper sheet assembly 600, a wave spring 300 and a damper upper cover 400, and the damper sheet assembly 600 is stacked and placed in the damper tray 200 to form a The overall damper tray assembly 500, the damper tray assembly 500 is placed in the inner cavity 101 of the damper housing 100, the wave spring 300 is installed in cooperation with the damper tray assembly 500, the damper upper cover 400 and the damper housing 100 installs and seals the damper tray assembly 500 in the inner cavity 101, wherein the damper sheet assembly 600 includes multiple stacked positioning pieces 601, friction plates 602 and rotating ring gear 603, adjacent positioning pieces 601 and rotating teeth The friction plate 602 is arranged between the rings 603. The biggest innovation of this patent is to integrate one or more thin plates such as the positioning plate 601, the friction plate 602,...

Embodiment 2

[0032] Such as Figure 7 As shown, most of the structures of Embodiment 1 and Embodiment 2 are the same, the difference is that the wave spring 300 is located between the damper tray assembly 500 and the damper housing 100, and the wave spring 300 is located in the inner cavity 101 of the damper housing 100 The bottom supports the damper tray assembly 500, and the damper upper cover 400 is threadedly connected with the damper housing 100, such as Figure 8 as well as Figure 9 As shown, the annular circular wall 401 of the damper upper cover 400 is pressed on the positioning piece 601, and the bottom of the damper tray 200 has a spring limit ring 205, which is stuck on the inner or outer ring of the wave spring 300 through the spring limit ring 205 , the damper tray 200 has a spring retaining ring 206 and a spring limit ring 207, one end of the wave spring 300 is pressed on the spring retaining ring 206, and the other end is pressed on the bottom of the cavity of the damper h...

Abstract

The invention belongs to the technical field of electric supporting rods, and provides a supporting rod damper. The damper comprises a damper shell, a damper tray, damping sheet assemblies, a wave spring and a damper upper cover, wherein the damping sheet assemblies are stacked and arranged in the damper tray to form an integral damper tray assembly; and the damper tray assembly is arranged in an inner cavity of the damper shell, the wave spring and the damper tray assembly are installed in a matched mode, and the damper upper cover and the damper shell are installed and seal the damper tray assembly in the inner cavity. The damper has the advantages that the damper has good assembling performance while providing the damping torque and is suitable for an automatic production line, the production efficiency is improved, meanwhile, product detection is facilitated through the structure, and it can be guaranteed that a positioning plate, a friction plate and a transmission gear ring are stacked in sequence; and another optimization scheme is adopted, the axial length of the damper can be effectively reduced while the beneficial effects are met, and the internal space of the supporting rod is saved on.
