DETAILED DESCRIPTION

[0033] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, the front motors, motors 6, on existing motorcycles are mostly installed in the area for storing the battery box 4, thereby occupying the space for storing the battery box 4, which results in the manufacturer needing to reduce the volume of the battery box 4 to provide for the installation of the motor 6, which results in a reduction in the number of batteries installed in the battery box 4, ultimately resulting in a shortened vehicle range, affecting the use of the vehicle.

[0035] Combination Figure 2 and Figure 3 As shown, a vehicle frame with a motor mounting assembly comprises: a vehicle main frame 1, a front end of which has a accommodating area 11 for mounting a battery box 4; a rear fork 2, which is hinged on the vehicle main frame 1; a motor mounting assembly 3, which is mounted in the vehicle main frame 1 at the rear side of the accommodating area 11 and is located in front of the rear fork 2; the mounting position of the motor mounting assembly 3 avoids the motor occupying the accommodating area 11, so that after the motor 6 is installed, the motor 6 will not reduce the volume of the battery box 4, thereby ensuring that the number of batteries will not be reduced, thereby ensuring the vehicle's endurance.

[0036] Combination Figures 3 to 6 The motor mounting assembly 3 includes: a mounting frame 31, on which an arc-shaped motor mounting position 311 is arranged, and the upper and lower ends of the mounting frame 31 are both provided with fixing parts 312; a connecting member 32, which is inserted into the fixing part 312, and the connecting member 32 is connected to the vehicle main frame 1, and the mounting frame 31 is installed on the vehicle main frame 1 through the connecting member 32.

[0037] A fixed crossbeam 12 and a fixed crossbeam 2 13 are provided on the vehicle main frame 1 at the rear side of the accommodating area 11, a fixing piece 121 is provided on the fixed crossbeam 12, and a fixing piece 2 131 is provided on the fixed crossbeam 13. In this scheme, the left and right ends of the fixed crossbeam 12 are both provided with fixing pieces 121, and the left and right ends of the fixed crossbeam 2 13 are both provided with fixing pieces 2 131; the connecting piece 32 has a connecting piece 1 321 and a connecting piece 2 322, the connecting piece 1 321 is formed by a screw and a nut being threadedly connected, and the connecting piece 2 322 is formed by a screw and a nut being threadedly connected; the connecting piece 1 321 is connected to the fixing piece 121, and both ends of the connecting piece 2 322 are connected to the fixing piece 2 131, so that the mounting frame 31 is installed on the vehicle main frame 1.

[0038] Connecting piece 1 321 is installed in the fixing portion 312 at the upper end of the mounting frame 31, and is used to fix the upper end of the mounting frame 31 to the fixing piece 121 of the fixed beam 12; the screw of connecting piece 2 322 is passed through the connecting cross bar 37, and the two ends of connecting piece 2 322 are passed through the fixing portion 312 at the lower end of the mounting frame 31, and is used to fix the lower end of the mounting frame 31 to the fixing piece 2 131 of the fixed beam 2 13.

[0039] The first connector 321 and the second connector 322 are respectively connected to the fixing parts 312 at the upper and lower ends of the mounting frame 31, and the first connector 321 and the second connector 322 respectively connect the upper and lower ends of the mounting frame 31 to the vehicle main frame 1, so that after the mounting frame 31 is installed on the vehicle main frame 1, the mounting frame 31 will not shake, thereby ensuring the stability of the motor when working.

[0040] Combination Figure 6 and Figure 7 The mounting frame 31 has an arc-shaped fixing plate 1 33 and a fixing plate 2 34, and a plurality of connecting holes 35 are opened on the fixing plate 1 33 and the fixing plate 2 34 for fixing the housing of the motor; a connecting cross bar 37 is provided at the lower end between the fixing plate 1 33 and the fixing plate 2 34 for passing the connecting member 2 322, and the connecting cross bar 37 is provided between the fixing plate 1 33 and the fixing plate 2 34, which can effectively ensure that the distance between the fixing plate 1 33 and the fixing plate 2 34 is not too small, so that when the fixing plate 1 33 and the fixing plate 2 34 are installed on the vehicle main frame 1, the fixing plate 1 33 and the fixing plate 2 34 will not squeeze the housing of the motor and cause deformation of the motor housing.

[0041] Combination Figure 6 and Figure 7 A limiting convex ring 36 is provided on the fixing portion 312 at the lower end of the fixing plate 1 33 and the fixing plate 2 34, and the two ends of the connecting cross bar 37 are respectively placed in the limiting convex ring 36 of the fixing plate 1 33 and the limiting convex ring 36 of the fixing plate 2 34. The limiting convex ring 36 prevents the connecting cross bar 37 from shaking, thereby improving the connection stability.

[0042] The edges of the connecting holes 35 on the fixing plate 1 33 and the fixing plate 2 34 protrude to form a positioning ring, which corresponds to the connecting holes on the motor 6. When the fixing plate 1 33 and the fixing plate 2 34 are connected to the motor 6, the positioning ring prevents the connecting holes from being exposed and affecting the appearance, and the positioning ring abuts against the edges of the connecting holes of the motor 6, thereby limiting the shaking of the motor 6.

[0043] Combination Figure 6 and Figure 7 A connecting portion 331 is protruded from the upper end of the fixing plate 33, and a connecting hole 35 is opened on the connecting portion 331. The connecting portion 331 cooperates with the fixing plate 33 to form a motor mounting position 311. The cooperation between the connecting portion 331 and the fixing plate 33 enables the motor mounting position 311 to form a major arc portion. When the major arc portion is connected to the motor housing, at least a portion greater than or equal to half of the circle of the edge of the motor housing is connected and fixed to the major arc portion.

[0044] A second connecting portion 341 protrudes from the upper end of the second fixing plate 34, and a connecting hole 35 is opened on the second connecting portion 341. The second connecting portion 341 cooperates with the second fixing plate 34 to form a motor mounting position 311. The second connecting portion 341 has the same design as the first connecting portion 331. The second connecting portion 341 and the first connecting portion 331 ensure the stability of the motor 6 installed on the mounting frame 31.

[0045] like Figure 8The main frame 1 at the rear side of the accommodating area 11 protrudes backward to form a protrusion 15, and a hinge 16 is arranged on the protrusion 15. The hinge 16 forms a hinge groove 17, and the hinge groove 17 is provided with a hinge shaft 18. The hinge shaft 18 is sleeved with a bearing 19, and the bearing 19 is movably connected to the front end of the rear fork 2. The protrusion 15 increases the length of the main frame 1, so that the motor mounting assembly 3 can be installed in front of the rear fork 2.

[0046] A fixing frame 5 is provided on the vehicle main frame 1 at the rear side of the accommodating area 11 , and the front end of the fixing frame 5 is used to fix the rear end of the battery box 4 to prevent the battery box 4 from squeezing the motor mounting assembly 3 .
