DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] A gearbox equipped with a wiring harness bracket comprises a gearbox body 1 and a wiring harness bracket 2, wherein one end of the gearbox body 1 is provided with a flange surface 3, and the wiring harness bracket 2 comprises a base plate 4, wherein the base plate 4 is fixedly connected to the flange surface 3 by bolts, and top plates 5 are respectively vertically installed on both sides of the top of the base plate 4, and a side plate 6 is vertically installed on one side of the base plate 4, and wiring harness fixings are respectively installed on the top plate 5 and the side plate 6, and a wiring harness is fixed on the wiring harness fixings.

[0025] The flange surface 3 at one end of the gearbox body 1 of the utility model is provided with a plurality of fixing holes spaced apart in the circumferential direction, and a mounting hole corresponding to the fixing hole on the flange surface 3 is provided on both sides of the base plate 4, and the fixing hole on the flange surface 3 and the mounting hole on the base plate 4 are fixedly connected by bolts, so that the base plate 4 is fixedly installed on the gearbox body 1. The top plate 5 and the base plate 4 are vertically arranged, and the side plate 6 and the base plate 4 are vertically arranged, so that the top plate 5 is horizontal, and the side plate 6 and the base plate 4 are vertical. The wiring harness is first fixed by the wiring harness fixing piece on the top plate 5, and then fixed by the wiring harness fixing piece on the side plate 6. The fixing structure is simple, and a fixed gap can be always maintained between the wiring harness and the gearbox, so as to avoid wire breakage and wiring harness wear caused by gap floating, and reduce the shaking of the wiring harness on the gearbox.

[0026] The base plate 4 is connected to the top plate 5 via the vertical plate 7 , and the vertical plate 7 is vertically connected to the top plate 5 via the bending portion 8 .

[0027] The utility model can increase the height of the top plate 5 by arranging the vertical plate 7, thereby increasing the height difference between the top plate 5 and the side plates 6, and avoiding obvious bending of the wire harness.

[0028] The bending portion 8 is provided with a recess 9 structure.

[0029] The utility model can enhance the strength of the bending portion 8 and reduce deformation by arranging the recess 9 structure on the bending portion 8.

[0030] The top plate 5 and the side plate 6 are respectively provided with limiting holes 10 for installing the wiring harness fixing parts, and the wiring harness fixing parts include a fixing seat 11 and a binding strap 14. The width of the fixing seat 11 is greater than the width of the limiting hole 10. The fixing seat 11 includes a plug 12 installed at the bottom thereof and can be inserted into the limiting hole 10. The two sides of the bottom of the plug 12 are symmetrically fixedly connected with limiting rods 13 extending upward. The limiting rods 13 are arranged to be inclined outward relative to the bottom of the plug 12, and one end of the binding strap 14 is fixedly installed on the top of the fixing seat 11.

[0031] The wiring harness fixing of the utility model is simple to install and firmly fixed. The width between the upper sides of the limiting rods 13 on both sides is greater than the length of the limiting hole 10. The limiting rod 13 is inclined relative to the bottom of the plug 12, so that the outer side of the limiting rod 13 is a wedge-shaped surface. When installing, it is only necessary to insert the plug 12 into the limiting hole 10. When inserting, the limiting hole 10 will squeeze the wedge-shaped surfaces of the limiting rods 13 on both sides, so that the limiting rods 13 on both sides are elastically bent inward at the same time until the limiting rods 13 are completely on the lower side of the top plate 5, and the limiting rods 13 on both sides return to their initial state. At this time, the limiting rods 1 3 are all on the outside of the limiting hole 10, so as to achieve the purpose of fixing the fixing seat 11. The wiring harness is fixed to the base by a binding strap 14, and the binding strap 14 can be a nylon tie or the like; the limiting hole 10 is an elliptical hole; the fixing seat 11 can be designed to be funnel-shaped, which can be compressed outward and elastically deformed when it contacts the top plate 5 or the side plate 6. When the limiting rod 13 is completely on the lower side of the top plate 5, the fixing seat 11 has a certain elastic force and makes the fixing seat 11 act on the plug 12 and the limiting rod 13 to move upward, so that the top surface of the limiting rod 13 is close to the bottom surface of the top 5 or the side plate 6.

[0032] The side panel 6 has a branch line limiting hole 15 on one side of the limiting hole 10, a fixing seat 11 is installed in the branch line limiting hole 15, a plug 12 on the fixing seat 11 is inserted into the branch line limiting hole 15, a fixing plate 16 is fixedly installed on the top surface of the fixing seat 11 on the branch line limiting hole 15, and the height of the top of the fixing plate 16 exceeds the height of the top of the side panel 6.

[0033] The utility model can effectively fix the branch wire harness of the gearbox low-voltage wire harness by opening a branch line limit hole 15 on the side plate 6 and installing a fixing seat 11 on the linear limit block, and installing a fixing plate 16 through the fixing seat 11. When in use, the branch wire harness is fixedly connected to the fixing plate 16 by an adhesive tape, and then the branch wire harness is fixed to the fixing plate 16, and friction and wear between the branch wire harness and the gearbox and the top plate 5 are avoided.

[0034] The top of the fixing plate 16 is bent toward the base plate 4 to form a flange 17 .

[0035] Both sides of the top plate 5 along the length direction of the base plate 4 are bent downward to form flanges 17 .

[0036] Both sides of the side plate 6 along the height direction of the base plate 4 are bent toward the base plate 4 to form flanges 17 .

[0037] The utility model provides flanges 17 on the fixing plate 16, the side plate 6 and the top plate 5 respectively, and the flanges 17 can eliminate the sharp edges of the fixing plate 16, the top plate 5 and the side plate 6, so as to prevent the wire harness from being cut during contact with the wire harness.

[0038] A car comprises the above-mentioned gearbox with a wiring harness bracket installed.
