Description

Technical Field

[0001] The utility model relates to the field of automobile interior decoration, in particular to a passenger handrail mounting bracket. Background Art

[0002] The passenger armrest is an essential component to ensure the safety of passengers in the car. When the car makes a sharp turn or brakes suddenly, the passengers can use the support provided by the armrest and its mounting structure to ensure their physical safety. The passenger armrest of the car must have sufficient strength, rigidity and position accuracy to ensure the operational reliability, safety and comfort of the passengers in the car during use. The common passenger armrests are currently fastened to the car body through two armrest mounting brackets connected to the upper side beam. The structural strength of the armrest and the armrest mounting bracket after assembly is poor, which is easy to deform during use. In extreme cases, it may be pulled off, affecting the normal use function of the armrest and the safety of the passengers. At the same time, the two brackets are relatively independent, and the dimensional accuracy of the armrest mounting surface is poor, which affects the damping function of the armrest after release, and then causes problems such as pinching the hand, and poor operating comfort.

[0034] like Figure 1-3 As shown, the utility model provides a passenger handrail mounting bracket structure, including a handrail mounting bracket body 100 and a bracket seat 200. The structure of the handrail mounting bracket body 100 is as shown in FIG. Figure 1 As shown, it includes a support beam and a support leg 130 extending from both ends of the support beam to the same side. The support leg 130 is L-shaped and has a support leg side 132 connected to the support beam and a support leg bottom 131 perpendicular to the side. The support leg bottom 131 has a through bolt hole. The support beam includes a concave feature surface 110 in the middle and a handrail mounting surface 120 symmetrically arranged on both sides of the concave feature surface 110. The concave feature surface 110 is provided with an installation direction indicating arrow hole 112 and installation tool through holes 111 located on both sides of the installation direction indicating arrow hole 112. The installation direction indicating arrow hole 112 is used to indicate the installation direction of the handrail mounting bracket, and the installation tool through hole 111 is used for the installation of subsequent components. The handrail mounting surface 120 is provided with an installation positioning hole 121 and a projection welding nut 122. The installation positioning hole 121 and the projection welding nut 122 are used to fix the passenger handrail.

After the bracket base 200 and the support leg 130 are welded, through bolt holes are formed on the bottom surface. By screwing an installation nut 101 into this bolt hole, the armrest installation bracket can be fixed to the upper side beam 300.

[0038] Among them, the welding method between the bracket base 200 and the support leg 130 is spot welding, and there is one welding spot on the side surfaces and bottom surfaces of the two respectively.
