These relative terms are for convenience of description and are generally not intended to require a particular orientation.

[0032] The specific implementation modes of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0033] like Figures 1 to 7 As shown, the automobile integrated bracket structure includes a bracket body, which is a flat structure formed by stamping and has a simple structure. Since the brackets on automobiles are used in batches and the usage is relatively large, the manufacturing is simple and the cost is effectively reduced.

[0034] The bracket body is provided with a wheel speed sensor wiring harness rubber sleeve interface 2, a caliper wiring harness rubber sleeve interface 3 and a brake pipe joint interface 1. The wheel speed sensor wiring harness rubber sleeve interface can position the wheel speed sensor wiring harness rubber sleeve 7, the caliper wiring harness rubber sleeve interface can position the caliper wiring harness rubber sleeve 6, and the brake pipe joint interface can position the brake pipe joint, thereby realizing effective positioning of the wheel speed sensor wiring harness, caliper wiring harness and brake pipe joint, forming a multifunctional integrated bracket structure; there is no need to set up many brackets on the whole vehicle, which effectively reduces the cost.

[0035] The wheel speed sensor wiring harness rubber sleeve interface and the caliper wiring harness rubber sleeve interface are an integrated opening structure; further, the opening structure on the bracket body is a continuous opening structure; the wheel speed sensor wiring harness and the caliper wiring harness are integrated and positioned in the same opening, with a simple structure, easy manufacture and relatively low cost.

[0036] The wheel speed sensor harness rubber sleeve interface 2, the caliper harness rubber sleeve interface 3 and the brake pipe joint interface 1 are all stamped and formed structures, and the plate parts are stamped and formed in one piece, which is easy to manufacture.

[0037] The continuous opening structure includes an inner opening and an outer opening, which are connected through an opening transition section. The specification size of the outer opening is larger than that of the inner opening. The inner opening forms a wheel speed sensor harness rubber sleeve interface, and the outer opening forms a caliper harness rubber sleeve interface. The wheel speed sensor harness and the caliper harness are integrated and positioned in the same opening, with a simple structure and easy manufacturing.

[0038] Specifically, the wiring harness rubber sleeve opening of the bracket body adopts a continuous opening; there is an intermediate transition section between the wheel speed sensor wiring harness rubber sleeve interface and the caliper wiring harness rubber sleeve interface, and an outer transition section is provided on the outer side of the caliper wiring harness rubber sleeve interface; the inner sheet metal opening size matches the wheel speed sensor wiring harness rubber sleeve diameter, the width of the intermediate transition section is the wheel speed sensor wiring harness rubber sleeve diameter - 2.5mm, the outer sheet metal opening size matches the EPB wiring harness rubber sleeve diameter, the width of the outer transition section 301 is the EPB wiring harness rubber sleeve diameter - 2.5mm, the positioning and assembly are simple, and the positioning is reliable.

[0039] The opening direction of the continuous opening is toward one side of the bracket body, which is convenient for the insertion operation of the wheel speed sensor wiring harness rubber sleeve and the caliper wiring harness rubber sleeve; the brake pipe joint interface is arranged at the corner of the bracket body to ensure the structural strength of the entire bracket body.

[0040] An anti-rotation structure 101 is provided on the bracket body corresponding to the edge of the brake pipe joint interface, which is used to clamp on the brake pipe joint to prevent rotation; preferably, the anti-rotation structure is a pair of convex clamping structures, and a clamping groove is provided on the brake pipe joint corresponding to the convex clamp. By clamping and fitting between a pair of convex clamps and corresponding clamping grooves, the brake pipe can be effectively prevented from rotating, and the positioning is reliable.

[0041] Specifically, the brake hose connector 9 and the brake hard pipe connector 8 cooperate and are positioned by a pair of convex clamps; the brake soft and hard pipe limit anti-rotation structure is designed as a boss with a height of about 5mm; the boss is stamped by a forming die; as shown in the figure Figure 1 As shown, the blanking die is used for blanking, and then the forming die is limited by the guide pins to form directly, which is simple to manufacture.

[0042] One side of the bracket body is provided with a fixing structure adapted to the outer edge of the rear axle 5 of the automobile; the bracket is fixed to the rear axle of the automobile through the fixing structure, and the wheel speed sensor wiring harness, caliper wiring harness and brake pipe are positioned through one bracket, eliminating many brackets, with a compact structure and easy layout and assembly.

[0043] Preferably, the fixing structure is an arc structure; the arc structure is an arc flange structure, and the arc flange structure is fixed by welding or bolts. The arc structure is matched with the rear axle of the automobile, and the fixed contact area between the two is relatively large, and the fixation is reliable.

[0044] Specifically, the arc-shaped flange structure can be formed by hot forging or bending and stamping to adapt to the outer edge of the rear axle of the automobile; the arc-shaped flange structure can be fixed on the rear axle of the automobile by welding, and the welding arc surface 4 is reliably fixed; or a screw hole is provided on the rear axle of the automobile, and a fixing hole is provided on the arc-shaped flange structure, and a bolt is passed through the fixing hole and fixed in cooperation with the screw hole.

[0045] The brake hard pipe of the brake line is relatively long and has a bent portion; in order to further improve the positioning reliability, the bracket body cooperates with the positioning card 10 to achieve double-point positioning; preferably, the positioning card is a bending structure, which is formed by multiple bending of sheet metal and is easy to form.

[0046] The upper part is bent to form a square structure with threaded holes on it, and the lower part is bent to form an inverted structure. The inverted structure and the upper square structure form a space for positioning the brake tube. The brake tube can be positioned by simply snapping it in, which is easy to operate.

[0047] The automobile integrated bracket structure of the present invention is reasonably designed, and can simultaneously position the wheel speed sensor harness, the caliper harness, and the brake soft and hard pipes. The wheel speed sensor harness and the caliper harness are integrated and positioned using the same opening, and have a simple structure, are easy to manufacture, and have relatively low cost.

[0048] The biggest advantage of the present invention is that it can reasonably utilize space, fix the wheel speed sensor wiring harness rubber sleeve and the EPB wiring harness rubber sleeve on the bracket at the same time, and also place the soft and hard pipe connection points on the same bracket; reduce the number of vehicle brackets used, and achieve the purpose of reducing the weight of the single vehicle.

[0049] The above is only an explanation of the preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0050] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
