Description
Technical Field
The utility model belongs to the technical field of the white automobile body, a two rows of safety belt coiler fixed knot construct is related to.
Background
The closest proposal of the utility model is a fixing bracket of a rear seat belt retractor of an automobile in patent CN 207860137U; with the utility model discloses the difference of well structure is 1) the structural style of support: in the patent, the bracket is turned downwards by a turned edge in the vehicle, and the welded edge of the bracket and the D column is very small, so that the rigidity is not favorably improved; the bracket is turned upwards by a turned edge outside the vehicle; and the structure of the utility model is just opposite: the bracket is turned upwards by a turned edge in the vehicle, and the lap edge of the bracket and the D column is very wide, has very many welding points and has very strong rigidity; the turnup outside the vehicle is turned downwards, and welding points arranged in the length direction are more than that of the structure; 2) in the patent, Z-direction nailing is performed when the safety belt retractor is installed; the arrangement position of the safety belt retractor of the utility model is very back and close to the D column, and the Z-direction nailing tool interferes with the D column, as shown in figure 1; therefore, the utility model provides a certain angle between the mounting surface and the Z direction, which solves the problem of interference between the tool gun and the D column; 3) the ware of rolling up in this patent is placed in the panel beating below, needs hang the couple of ware of rolling up from the below operation and stretch in T type groove, and the hand is scraped easily and shelters from the operation to the turn-ups of visual poor and support, and the installation is inconvenient. And the utility model discloses a coiler is installed in the support top, and is visual better, and it is more convenient to operate.
The arrangement of two rows of safety belts at present divides according to the meshbelt direction that stretches out from the coiler body, and there are two kinds of forms mainly, and the level is arranged and vertical arranging, and the meshbelt stretches out arranging that the direction is the horizontal direction and arranges promptly for the level. Compared with the vertical arrangement, the two rows of safety belts which are arranged horizontally have better compatibility, and have the following advantages that 1) a vehicle body does not need to be provided with a guide structure, and a guide ring at the position of 1-2 is omitted; 2) the influence of the inner and outer decoration shapes is small, and the C column upper guard plate does not need to be matched; 3) the appearance is attractive, and the back door can not see the support of the safety belt webbing when being opened; 4) the angle window has good visual field, and the vertically arranged safety belt needs the angle window black belt to shield, so that the front edge black area of the angle window is very wide.
However, such horizontal arrangement is a design difficulty for the vehicle body structure of SUV vehicles: 1) the two-compartment car is not provided with a wrapping frame, and a safety belt retractor which is horizontally arranged cannot be fixed on the wrapping frame; the vehicle body brackets at two ends of the similar wrapping frame can only grow out in the area from the C column to the D column; if the bracket is large in size, the weight of the body in white is increased greatly; 2) the tail of the compact SUV enables the distance between the D column and the retractor to be very close, so that the tool space is insufficient when the electric tightening tool performs Z-direction torque driving; as shown in fig. 1, the sleeve basically props against the D column, and the electric tightening tool cannot be arranged; 3) the support hangs on C post inner panel, and the rigidity is relatively poor, leads to the interior device abnormal sound of safety belt easily.
