[0033] In the description of the present invention, a first feature “above”, “over” and “above” a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature.

[0034] The vehicle motor bracket 1 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 6 As shown, the vehicle motor bracket 1 according to the embodiment of the present utility model includes a transverse plate portion 100 , a side plate portion 200 and a lower connecting plate portion 300 .

[0036] The transverse plate portion 100 extends horizontally and is suitable for being mounted on the suspension cushion 11 of the vehicle frame 10. The side plate portion 200 is connected to one side of the transverse plate portion 100 and is located on the inner side of the suspension cushion 11. The thickness of the side plate portion 200 gradually decreases from the transverse plate portion 100 to the bottom, and the side plate portion 200 extends downward. The lower connecting plate portion 300 is connected to the bottom of the side plate portion 200 and extends obliquely toward the center of the width direction of the vehicle frame 10. The lower connecting plate portion 300 supports and is mounted on the bottom of the motor 20.

[0037] A weight-reducing opening 301 is configured at the bottom of the lower connecting plate portion 300 , and the weight-reducing opening 301 is located in the middle of the lower connecting plate portion 300 in the front-to-back direction.

[0038] For example, the left longitudinal beam and the right longitudinal beam of the vehicle frame 10 are respectively installed with a vehicle motor bracket 1, and the vehicle motor bracket 1 supports and installs the motor 20 on the left and right sides of the motor 20. The side of the side plate portion 200 facing the vehicle motor 20 is configured as a plane extending in the vertical direction, parallel to the side of the motor 20. The suspension cushion 11 is supported on the bottom of the transverse plate portion 100. The transverse plate portion 100 and the lower connecting plate portion 300 are respectively located on opposite sides of the thickness direction of the side plate portion 200, so that the vehicle motor bracket 1 forms a "seahorse-shaped" bracket in the front and rear projection direction. And the vehicle motor bracket 1 is a casting, and the transverse plate portion 100, the side plate portion 200 and the lower connecting plate portion 300 are cast together into an integral part.

[0039] Among them, the cross plate portion 100 is installed on the suspension cushion 11 of the frame 10, so that the vehicle motor bracket 1 can be supported and shock-absorbed by the suspension cushion 11, and the vibration of the motor 20 is absorbed by the suspension cushion 11. The vibration of the motor 20 is transmitted to the suspension cushion 11 of the frame 10 through the lower connecting plate portion 300, the side plate portion 200 and the cross plate portion 100, bringing a comfortable riding experience to the occupants.

[0040] According to the vehicle motor bracket 1 of the embodiment of the utility model, a weight-reducing opening 301 is constructed at the bottom of the lower connecting plate portion 300, and the front and rear sides of the weight-reducing opening 301 respectively form support arm structures to maintain the installation with the motor 20. The front and rear sides of the lower connecting plate portion 300 are separated by the weight-reducing opening 301 to form a "dovetail" structure. The front and rear parts of the lower connecting plate portion 300 can have a tendency to move relative to each other within a certain range, thereby preventing stress concentration in the middle part of the lower connecting plate, reducing the stress in the middle part of the lower connecting plate portion 300, and preventing the middle part of the lower connecting plate portion 300 from cracking.

[0041] The angles of the side panel 200 and the cross panel 100 extend in the horizontal and vertical directions respectively. The stress at the connection between the cross panel 100 and the side panel 200 is relatively large. By setting a thicker thickness at the connection of the side panel 200 toward the cross panel 100, the connection strength between the cross panel 100 and the side panel 200 can be improved to prevent cracking at the connection between the side panel 200 and the cross panel 100. The thickness of the side panel 200 gradually decreases from the cross panel 100 to the bottom, so that the cross section of the side panel 200 forms a trapezoidal shape, and the force transmission is smoother. The side panel 200 is roughly parallel to the web of the frame longitudinal beam, making full use of the gap between the two sides of the motor 20 and the longitudinal beam of the frame 10, with higher space utilization, and will not occupy the layout of other structures.

[0042] Therefore, the motor bracket according to the embodiment of the utility model has the advantages of high force strength, small space occupation, and light weight.

[0043] In addition, while using the motor bracket of the embodiment of the utility model to support and install the motor 20, an additional hanging bracket can be installed on the top of the motor 20 to further fix the motor 20 to ensure the installation firmness of the motor 20.

[0044] In some specific embodiments of the present invention, Figure 5 , Figure 6 As shown, the lower connecting plate portion 300 includes a front connecting plate portion 310 and a rear connecting plate portion 320 .

[0045] The front connecting plate portion 310 is connected to the front portion of the side plate portion 200 . The rear connecting plate portion 320 is connected to the rear portion of the side plate portion 200 , and the weight-reducing opening 301 is formed between the front connecting plate portion 310 and the rear connecting plate portion 320 .

[0046] The bottoms of the front connecting plate portion 310 and the rear connecting plate portion 320 are separated by the front and rear weight-reducing opening 301, and the front connecting plate portion 310 and the rear connecting plate portion 320 are respectively supported and installed on the front and rear sides of the bottom of the motor 20. Thus, the front connecting plate portion 310 and the rear connecting plate portion 320 can be subjected to force respectively, and the front connecting plate portion 310 and the rear connecting plate portion 320 can have a tendency to move relative to each other within a certain range, thereby preventing stress concentration between the front connecting plate portion 310 and the rear connecting plate portion 320, and preventing the middle portion of the lower connecting plate portion 300 from cracking.

[0047] Furthermore, if Figure 1 As shown, the height of the lowest point of the rear connecting plate portion 310 is lower than the height of the lowest point of the front connecting plate portion 320 .

[0048] Specifically, the vehicle motor bracket 1 is arranged to be gradually tilted downward from front to rear. Since the power line of the vehicle extends downward from front to rear, the motor 20 and the vehicle motor bracket 1 also adapt to the tilt direction of the vehicle power line to ensure the reliable installation of the motor 20.

[0049] In some specific embodiments of the present invention, Figure 5 As shown, the upper surface of the front connecting plate portion 310 is constructed with a front supporting boss 311 suitable for supporting the motor 20, and the upper surface of the rear connecting plate portion 320 is constructed with a rear supporting boss 312 suitable for supporting the motor 20. The front supporting boss 311 and the rear supporting boss 312 are suitable for installing the motor 20 by passing fasteners.

[0050] The front supporting boss 311 and the rear supporting boss 312 protrude toward the motor 20 and are supported by the motor 20, and the fasteners are passed through the front supporting boss 311 and the rear supporting boss 312 and installed on the motor 20. The supporting areas of the front supporting boss 311 and the rear supporting boss 312 are relatively small, which can better provide positioning for the installation of the motor 20, and the front supporting boss 311 and the rear supporting boss 312 firmly fix the motor 20 to the vehicle motor bracket 1 by passing the fasteners, ensuring that the motor 20 will not deviate relative to the vehicle motor bracket 1.

[0051] In some specific embodiments of the present invention, Figure 5 , Figure 6 As shown, the projection of the weight-reducing opening 301 is configured to be trapezoidal, and the weight-reducing opening 301 extends upward to the side plate portion 200 .

[0052] In this way, the overall weight of the vehicle motor bracket 1 can be further reduced, and the front connecting plate portion 310 and the rear connecting plate portion 320 can be completely separated. While ensuring the structural strength, the weight can be reduced to a greater extent by hollowing out, forming a large area of ​​the weight-reducing opening 301. The weight-reducing opening 301 is configured as a trapezoid, and the front connecting plate portion 310 and the rear connecting plate portion 320 both form a transition structure that is wide at the top and narrow at the bottom. The transmission of force between the front connecting plate portion 310 and the rear connecting plate portion 320 is relatively smooth, which greatly saves materials and reduces weight, and can reduce the weight by 2 / 5.

[0053] In some specific embodiments of the present invention, Figure 1 As shown, the front side surface and the rear side surface of the lower connecting plate portion 300 are parallel to each other.

[0054] Specifically, if Figure 1 As shown, the front side surface of the front connecting plate portion 310 can be limited by the limiting flange on the front side of the motor 20, and the rear side surface of the rear connecting plate portion 320 can be limited by the flange of the motor 20. Thus, the front and rear sides of the lower connecting plate portion 300 are respectively matched with the front and rear edges of the motor 20, and the vehicle motor bracket 1 and the motor 20 form a better limit, which is convenient for the installation of the motor 20 and improves the stability of the motor 20.

[0055] In some specific embodiments of the present invention, Figure 4 As shown, one side of the side plate portion 200 facing the motor 20 extends vertically and is perpendicular to the top surface of the transverse plate portion 100 .

[0056] Thus, when the top plate portion is mounted on the suspension cushion 11, the side plate portion 200 extends in the vertical direction and is parallel to the side surface of the motor 20, for example, Figure 2 As shown, the side plate portion 200 is spaced apart from the side surface of the motor 20 , the motor 20 is placed between the side plate portions 200 on both sides, and the lower connecting plate portion 300 is supported on the bottom of the motor 20 .

[0057] Furthermore, if Figure 5 and Figure 6 As shown, the width of the side plate portion 200 gradually increases from the horizontal plate portion 100 to the bottom. In addition, the width of the side plate portion 200 gradually increases from top to bottom, forming a trapezoidal or triangular structure. The side plate portion 200 is connected between the horizontal plate portion 100 and the lower connecting plate portion 300, which plays a better role in force transmission.

[0058] According to some specific embodiments of the present invention, Figure 6 As shown, the side surface of the side plate 200 facing away from the motor 20 is formed with a convex ridge 210 and a concave ridge 220. The two sides of the convex ridge 210 form two planes with an angle greater than 180°, and the two sides of the concave ridge 220 form two planes with an angle less than 180°.

[0059] For example, the convex ridges 210 are respectively located on the front and rear sides of the side panel 200, and the concave ridges 220 are also located on the front and rear sides of the side panel 200 and on the outside of the convex ridges 210. The convex ridges 210 and the concave ridges 220 divide the side panel 200 into multiple triangular planes. The surface of the side panel facing away from the motor 20 forms a structural surface that undulates along the thickness direction. Compared with a plane, it has better deformation ability and better toughness to prevent cracking.
