[0025] The specific embodiments of the present application are further described in detail below with reference to the drawings, by describing the embodiments, the purpose is to help the technical personnel in the field to have more complete, accurate and in-depth understanding of the inventive concept and technical scheme of the present application, and to help its implementation.

[0026] As Figures 1 to 5 shown, the motor water pipe fixing support includes a mounting plate 1, the mounting plate 1 is provided with a mounting hole 4, the upper end of the mounting plate 1 is provided with a support plate 2, and the support plate 2 is provided with a fixed groove 3. The mounting plate 1 is bent 90° upwards to form the support plate 2, one end of the support plate 2 is bent upwards to form the fixed groove 3, the fixed groove 3 is used for clamping the motor water pipe 8, realizing the fixation of the motor water pipe 8, a circular mounting hole 4 is formed on the mounting plate 1, which is used for mounting the bolt 11 so as to be mounted on the rear axle flange 9

[0027] The fixed groove 3 is of annular structure, and the fixed groove 3 is provided with an opening 12 between the support plate 2. The opening 12 is provided to facilitate the motor water pipe 8 to enter the fixed groove 3 in the radial direction along the opening 12, the fixed groove 3 is designed as an arc shape, the contact surface with the surface of the motor water pipe 8 is larger, and it is adapted to the pipe wall shape, so as to ensure higher fixation stability of the motor water pipe 8.

[0028] As Figures 1 to 4 shown, one end of the mounting plate 1 is provided with a stop block 5, the stop block 5 is located below the fixed groove 3, and the stop block 5 is vertically arranged with the mounting plate 1. The stop block 5 is composed of a bent part and is vertically arranged with the mounting plate 1. When the fixing support is installed, the mounting plate 1 is parallel to the end surface of the rear axle flange 9, the stop block 5 will abut against the upper end of the rear axle flange 9, and the mounting plate 1 will not rotate due to friction when the bolt 11 is screwed, avoiding the inconvenience of assembly.

[0029] As Figure 1 shown, the end of the fixed groove 3 is provided with an arc plate 6. In order to prevent the sharp edge of the opening 12 of the fixed groove 3 from cutting the motor water pipe 8, the end of the fixed groove 3 is bent outward to form the arc plate 6. The surface of the fixed groove 3 is treated by dipping, which can further prevent the sharp edge of the fixed groove 3 from cutting the motor water pipe 8.

[0030] As Figure 1As shown, the connecting part of the mounting plate 1 and the supporting plate 2 is provided with a rib 7, and the ribs 7 are arranged in pairs. The two ribs 7 arranged at the connecting part of the mounting plate 1 and the supporting plate 2 can improve the rigidity of the fixing support, increase the modal, and prevent the motor 10 from resonating with the fixing support. Since the mounting plate 1 and the supporting plate 2 are sheet metal bending structures, the ribs 7 arranged at the bending parts of the two plates can avoid springback and improve the structural strength of the fixing support.

[0031] As shown in Figure 2 , the arc-shaped plate 6 is spaced apart from the supporting plate 2 by 5-10 mm. In order to prevent abnormal noise caused by too small gap between the arc-shaped plate 6 at the end of the fixing groove 3 and the upper surface of the supporting plate 2, and prevent the water pipe from being pulled out due to too large gap, the gap between the arc-shaped plate 6 at the end of the fixing groove 3 and the upper edge of the supporting plate 2 is preferably 5-10 mm.

[0032] As shown in Figure 4 and Figure 5 , the motor 10 is arranged below the motor water inlet pipe 8. The motor 10 includes a rear axle flange 9, the mounting plate 1 is connected to the rear axle flange 9 by bolts 11, the motor water inlet pipe 8 passes through the fixing groove 3, and the stop block 5 abuts against the upper end of the rear axle flange 9. The fixing support is assembled and fixed by the bolts 11, the motor water inlet pipe 8 is clamped and fixed by passing through the fixing groove 3, and the stop block 5 abuts against the upper end of the rear axle flange 9, which can prevent the fixing support from rotating with the tightening of the bolts 11 when the fixing support is assembled with the rear axle flange 9.

[0033] The fixing support is a sheet metal bending structure, the bending angle of the mounting plate 1 and the supporting plate 2 is 90°, and the bending radius of the connecting part of the mounting plate 1 and the supporting plate 2 is greater than twice the thickness of the sheet metal. The connecting position of the fixing support and the rear axle flange 9 adopts a single-piece structure, which can avoid stress concentration and torque attenuation of the bolts 11, and prevent the bolts 11 from loosening, compared with a multi-piece structure. In order to prevent stress concentration at the bending part of the sheet metal, the bending radius of the connecting part of the mounting plate 1 and the supporting plate 2 should be greater than twice the thickness of the sheet metal.

[0034] As shown in Figures 1 to 3 , the mounting plate 1, the supporting plate 2, the fixing groove 3, the arc-shaped plate 6, and the stop block 5 are integrated structures. The above components are integrally formed on the fixing support to form a monolithic structure, which can effectively avoid the adverse effects of welding defects on the fixing support.

[0035] As shown in Figures 1 to 3 , the edges of the mounting plate 1 and the supporting plate 2 are arc-shaped transitions. The arc-shaped transition treatment of the end position of the fixing support can reduce stress concentration and is beneficial to ensuring reliable overall performance.

[0036] The motor water inlet pipe fixing support solves the problems of easy warping, poor flatness, stress concentration after installation and easy torque attenuation of the installation surface of the existing double-laminated ring-shaped support. The overall sheet metal bending structure has excellent fatigue resistance, no stress concentration and torque attenuation, the overall structure is simple, easy to process and manufacture, high production efficiency and low cost, after the fixing support is fixed with the rear axle flange 9, the single-layer plate structure is not easy to warp, there is no interlayer stress concentration and torque attenuation of the fixing bolt 11, and bolt 11 connection failure and loosening are avoided.

[0037] The utility model has been described above in conjunction with the drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned manner. As long as various non-essential improvements are made by using the method concept and technical solution of the utility model; or without improvement, the above-mentioned concept and technical solution of the utility model are directly applied to other occasions, which are all within the protection scope of the utility model.
