[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Combined with appendix Figure 1-4 As shown, a motor bracket structure mainly consists of three components: a motor-side bracket 1, a frame-side bracket 2, and a rubber pad 3. The motor-side bracket 1 and frame-side bracket 2, each integrally formed and with an "L"-shaped bend, are positioned opposite each other on their inner sides and are connected to the rubber pad 3. The rubber pad 3 is readily available and can be used directly. It connects the motor and frame respectively via the other side of the motor-side bracket 1 and frame-side bracket 2. The motor bracket structure is connected to the motor, frame, and rubber pad 3 via bolts. This motor bracket structure supports the motor, and the rubber pad 3 reduces vibration damage.

[0027] Specifically, the motor-side bracket 1 is mainly a bracket for connecting the motor 4, and then the motor-side bracket 1 is connected to the rubber pad 3. The motor-side bracket has an "L"-shaped bent structure. The main stress point of this bent structure is located at the first bend 11. It also includes the first connecting surface 12 of the pad and the motor connecting surface 13 connected through the first bend 11. The integral molding concentrates the main stress point on the motor-side bracket 1 made of sheet metal, thereby reducing the probability of breakage when the motor-side bracket is subjected to force at the main stress point.

[0028] Preferably, the interior of the "L"-shaped bending structure has a number of first reinforcing ribs 14. The first reinforcing ribs 14 are used to connect the first bending part 11, the first connecting surface 12 of the pad block and the motor connecting surface 13. The support of the number of first reinforcing ribs 14 can make the bending structure achieve a more uniform distribution of stress in the stressed part, so that the pressure on the bending structure is not concentrated at one point.

[0029] The motor connecting surface 13 is fitted to the motor to allow the motor-side bracket 1 to be attached to the motor. Several first connecting holes 15 on the motor connecting surface 13 are aligned with corresponding holes on the motor. Then, bolts are used to connect the motor connecting surface 13 and the motor 4, with multiple bolts used for reinforcement at the point where the motor 4 and the bracket are attached. In this embodiment, four first connecting holes 15 are provided, and these four first connecting holes 15 are arranged in a rectangular pattern. Furthermore, the size and number of holes connecting the motor and the first connecting holes 15 on the motor connecting surface 13 can be varied accordingly, and the bolt size also changes as the hole positions change.

[0030] Meanwhile, at least one second connection hole 16 is provided on the first connecting surface 12 of the pad of the motor side bracket 1. The second connection hole 16 is connected and fixed to the rubber pad 3 using bolts.

[0031] With the first connecting surface 12 of the pad and the motor connecting surface 13 already connected, the first bending portion 11 provides a supporting connection between the first connecting surface 12 of the pad and the motor connecting surface 13. The motor side bracket 1 is connected by two ribs on each side, and a third rib is added in the middle of the two ribs to form a first reinforcing rib 14. This provides support to both ends of the first bending portion 11, distributing the force and supporting the first bending portion 11. Furthermore, under stress, the two sides of the first bending portion 11 can be appropriately thickened to achieve a more uniform force distribution, reduce wear on the motor side bracket, and improve its service life.

[0032] The frame side bracket 2 is mainly used for fitting and connecting the frame 5, and the other end is connected to the rubber pad 3. The frame side bracket 2 also uses an "L"-shaped bending structure, having a second bending portion 21, and including a second connecting surface 22 of the pad and a frame connecting surface 23 connected through the second bending portion 21. Several third connecting holes 25 are provided on the frame connecting surface 23. Bolts are used to align and fix the frame connecting surface 23 and the holes on the frame 5. The number and size of the third connecting holes can also be changed, and the corresponding bolts should also be changed accordingly. Meanwhile, a rubber pad 3 is connected to the other end of the second bending portion 21, i.e., the second connecting surface 22 of the pad. In this embodiment, several fourth connecting holes 26 are formed on the second connecting surface 22 of the pad for fixing to the rubber pad 3 with bolts. The number and size of the holes can also be changed accordingly, and the rubber pad and bolts should also be changed accordingly. At this point, the second bending portion 21 has been fixed to the two ends that need to be connected. Next, the second bending portion 21 is reinforced by welding, that is, the second connecting surface 22 of the connecting pad, the frame connecting surface 23, and the second reinforcing rib 24 of the second bending portion 21 are set on the inner side of the frame side bracket 2. This improves the stress on the bracket and enhances the life and strength of the motor bracket due to the presence of the rib. At the same time, the concentrated stress points of the frame side bracket can be partially thickened to distribute the stress on the bracket and improve the efficiency of the bracket.

[0033] Preferably, in this embodiment, the first connecting surface and the second connecting surface of the pad are arranged in parallel.

[0034] Connection principle: Assemble the motor connecting surface 13 of the motor-side bracket 1 and fix the motor-side bracket 1 to the motor using bolts. At this time, the motor-side bracket 1 is fixed to the motor. At the same time, connect the motor-side bracket 1 to the rubber pad 3 and fix it with bolts. At this time, the motor-side bracket 1 is fixed. Next, fit the frame-side bracket 2 to the frame and fix the frame connecting surface 23 of the frame-side bracket 2 to the frame using bolts. At the same time, fix the second connecting surface 22 of the pad of the frame-side bracket 2 to the rubber pad 3. At this time, the three parts are connected.

[0035] This utility model has the following advantages:

[0036] (1) Increase the safety of motor support: The motor support structure uses a motor side support and a frame side support that are integrally formed. Through the reinforcement mechanism of the two bending parts, namely the first bending part and the second bending part, the service life of the motor support structure can be increased and the efficiency of the motor support structure can be improved. At the same time, the motor support structure can be thickened and reinforced to increase its safety.

[0037] (2) Increase motor transmission efficiency: Because the existing rubber pads are used to connect the side brackets of the frame and the rubber pads, the vibration is reduced and the damping effect is increased in terms of structural vibration transmission. Because the damping effect is increased, the vibration of the motor can be reduced. At this time, the energy loss of the motor is reduced, and the energy consumed by vibration is reduced, thus increasing the transmission efficiency of the motor.

[0038] (3) Increase vehicle safety and stability: Because it improves the safety of motor support and the transmission efficiency of motor, and reduces motor vibration, the service life of motor bracket structure is extended. This reduces safety accidents caused by motor fixing problems and increases vehicle safety and stability.

[0039] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
