Description

Technical Field

[0001] This application relates to the field of vehicle assembly technology, specifically to a motor mounting mechanism and a vehicle. Background Technology

[0002] An electric drive system typically consists of core components such as a motor, transmission, and differential, and is connected to the vehicle frame via a motor mounting mechanism. This motor mounting mechanism not only bears the entire weight of the electric drive system but also withstands alternating loads from driving torque, road impacts, and other factors during operation. The reliability of its connection structure directly affects the vehicle's NVH performance and driving safety. NVH performance refers to the combined performance of Noise, Vibration, and Harshness.

[0003] In current electric drive assembly processes, the connection between the motor mounting mechanism and the vehicle frame is generally achieved using a "flat flange fit + bolt tightening" method. However, this assembly process heavily relies on external tooling for positioning and guidance, resulting in problems such as low assembly efficiency and insufficient connection stability. Summary of the Invention

[0004] In view of the above, it is necessary to provide a motor mounting mechanism and a vehicle to improve assembly efficiency and stability.

[0005] One embodiment of this application provides a motor mounting mechanism for mounting on a vehicle frame having multiple mounting members. Each mounting member includes a mounting connector, a mounting support, and a locking body. The mounting connector is fixedly sleeved on the mounting support. The motor mounting mechanism includes a housing and multiple connecting units. The housing is used to mount the electric drive assembly and has multiple mounting surfaces, each with a mounting hole. The mounting holes correspond one-to-one with the multiple mounting members. The multiple connecting units correspond one-to-one with the multiple mounting holes. At least one of the multiple connecting units is a centering member, and the remaining connecting units are stop members. The centering member is connected to the housing and surrounds the mounting surface. The centering member and the mounting surface form a centering groove that communicates with the mounting hole. The lower end of the centering groove is open, and the width of the opening gradually decreases from the lower end to the upper end of the centering groove to guide the corresponding mounting connector to be accommodated in the centering groove. The stop members are connected to the housing and located on the upper side of the corresponding mounting surface to abut against the mounting support. When each locking body passes through the corresponding suspension connector and suspension support and is threadedly connected to the mounting hole to fix the housing and suspension component, the mounting surface abuts against the corresponding suspension support in the axial direction of the mounting hole, the stop abuts against the corresponding suspension support in the radial direction of the mounting hole, and the centering component abuts against the corresponding suspension support in the radial direction of the mounting hole.

[0006] In the aforementioned motor mounting mechanism, the lower end of the centering slot has an open structure, and the width of the open end of the centering slot gradually decreases from the lower end to the upper end. This allows at least one centering component to guide the corresponding mounting connector to be accommodated in the centering slot when the motor mounting mechanism is installed on the frame. This enables at least one centering component to work with a stop component to guide the motor mounting mechanism in the vertical direction, thereby reducing the debugging cycle. In addition, the stop component can stop the corresponding mounting support in the vertical direction, reducing the excessive descent of the entire motor mounting mechanism, thereby improving the assembly efficiency of the motor mounting mechanism and the frame. Furthermore, when the housing and the suspension are connected and fixed, the mounting surface abuts against the corresponding suspension support in the axial direction of the mounting hole, the stop abuts against the corresponding suspension support in the radial direction of the mounting hole, and the centering component abuts against the corresponding suspension support in the radial direction of the mounting hole. This allows the centering component and the stop component, together with the suspension, to limit the motor suspension mechanism in the axial and radial directions of the mounting hole, respectively. This reduces the sway of the motor suspension mechanism relative to the frame, thereby improving the connection stability between the motor suspension mechanism and the frame.

[0007] In some embodiments, the centering component includes a limiting body and two guide bodies. The limiting body is connected to the housing and located above the mounting hole. The two guide bodies are respectively connected to the housing and located on opposite sides of the limiting body, with one end of each guide body connected to the limiting body. The distance between the two guide bodies increases in the direction away from the limiting body, and the two guide bodies are symmetrically arranged about the limiting body. The two guide bodies, the limiting body, and the mounting surface form a centering groove.

[0008] In some embodiments, the centering member includes two guide bodies. Each guide body is connected to the housing. One end of each guide body is connected and located above the mounting hole, while the other ends of each guide body are spaced apart and located below the mounting hole. The distance between the two guide bodies gradually increases in the direction away from the connection point, and the two guide bodies are symmetrically arranged about the mounting hole. The two guide bodies and the mounting surface form a centering groove.

[0009] In some embodiments, the surface of each guide facing another guide is an arcuate surface or a plane.

[0010] In some embodiments, each guide includes a plurality of guide segments connected in sequence, each guide segment being inclined relative to the axial direction of the mounting hole, and the inclination rate of the guide segment gradually decreasing along the opening direction away from the centering groove.

[0011] In some embodiments, the surface of the limiting body facing the corresponding mounting hole and the surface of the stop member facing the corresponding mounting hole are both recessed structures to accommodate a portion of the suspension support.

[0012] In some embodiments, the limiting body and the stop are both elastic structures.

[0013] In some embodiments, flexible structures are respectively attached to the surface of the limiting body facing the corresponding mounting hole and the surface of the stop member facing the corresponding mounting hole.

[0014] In some embodiments, the housing further has a plurality of guide ramps, which are respectively provided in correspondence with a plurality of mounting surfaces. Each guide ramp is located below the corresponding mounting hole and connected to the corresponding mounting surface. The distance between each guide ramp and the corresponding mounting surface in the axial direction of the mounting hole gradually increases in the direction away from the mounting hole, so as to slide against the corresponding suspension support.

[0015] One embodiment of this application also provides a vehicle, including a frame and the motor mounting mechanism described above. The frame has multiple mounting members, each corresponding to a plurality of mounting holes in the motor mounting mechanism. Each mounting member includes a mounting connector, a mounting support, and a locking body. The mounting connector is fixedly sleeved on the mounting support. Each locking body passes through the corresponding mounting connector and mounting support and is threadedly connected to the mounting hole to fix the housing and the mounting member.

[0016] The motor mounting mechanism in the aforementioned vehicle can improve the assembly efficiency and connection stability of the motor mounting mechanism and the frame, thereby improving the vehicle's performance. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two elements or the interaction between two elements. In the description of this application, it should be noted that "multiple" means two or more, unless otherwise expressly and specifically limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1 , Figure 2 and Figure 3 One embodiment of this application provides a vehicle 100, including a frame 110 and a motor mounting mechanism 120. The frame 110 has a plurality of mounting members 111, each mounting member 111 including a mounting connector 1111, a mounting support 1112 and a locking body 1113. The mounting connector 1111 is fixedly sleeved on the mounting support 1112, and each locking body 1113 passes through the corresponding mounting connector 1111 and mounting support 1112 and is connected to the motor mounting mechanism 120.

[0029] For example, the suspension support 1112 may be a bushing, which is generally a hollow cylinder, and the locking body 1113 may be a bolt.

[0030] For example, the number of suspension elements 111 is four. In other embodiments, the number of suspension elements 111 may also be three, five or more.

[0031] For ease of description, a directional coordinate system has been added to the accompanying drawings. Specifically, the driving direction of the vehicle 100 is taken as the front-rear direction, the axis of the mounting hole 121b is parallel to the front-rear direction, the left-right direction is one radial direction of the mounting hole 121b, i.e., the width direction of the vehicle 100, and the up-down direction is another radial direction of the mounting hole 121b, i.e., the height direction of the vehicle 100. Among these, the front-rear direction, the left-right direction, and the up-down direction are mutually perpendicular.

[0032] Please see Figure 3 and Figure 4 The motor mounting mechanism 120 includes a housing 121 and multiple connecting units 122. The housing 121 is used to mount the electric drive assembly and has multiple mounting surfaces 121a, each mounting surface 121a having a mounting hole 121b, and the multiple mounting holes 121b are correspondingly arranged with multiple suspension members 111. Multiple connecting units 122 are provided one-to-one with multiple mounting holes 121b. At least one of the multiple connecting units 122 is a centering member 122a, and the remaining connecting units 122 are stop members 122b. The centering member 122a is connected to the housing 121 and is arranged around the mounting surface 121a. The centering member 122a and the mounting surface 121a form a centering groove 120a that communicates with the mounting hole 121b. The lower end of the centering groove 120a has an open structure, and the width of the open end of the centering groove 120a gradually decreases from the lower end to the upper end of the centering groove 120a, so as to guide the corresponding suspension connector 1111 to be accommodated in the centering groove 120a. The stop member 122b is connected to the housing 121 and is located on the upper side of the corresponding mounting surface 121a, and is used to abut against the suspension support 1112.

[0033] For example, the four suspension members 111 are arranged in a generally rectangular shape, and the housing 121 includes a left housing portion 1211, a transmission housing portion 1213 and a right housing portion 1212 arranged sequentially in the left-right direction. The transmission housing portion 1213 is connected to the left housing portion 1211 and the right housing portion 1212 respectively by bolts.

[0034] For example, there are four connecting units 122, one of which is a centering member 122a, and the other three connecting units 122 are stop members 122b. The centering member 122a is located at the rear end of the left shell 1211, and the front end of the left shell 1211, the front end of the right shell 1212, and the rear end of the right shell 1212 each have a stop member 122b.

[0035] In other embodiments, the specific positions of the stop member 122b and the centering member 122a can also be set based on the overall structural requirements of the housing 121, as long as each mounting surface 121a is provided with a corresponding connecting unit 122.

[0036] In other embodiments, the number of connecting units 122 may be three, five or more, and the positions of the multiple connecting units 122 may be set based on the specific requirements of the housing 121.

[0037] Please see Figure 3 , Figure 5 and Figure 6 When each locking body 1113 passes through the corresponding suspension connector 1111 and suspension support 1112 and is threadedly connected to the mounting hole 121b to fix the housing 121 and the suspension member 111, the mounting surface 121a abuts against the corresponding suspension support 1112 in the front-back direction, the stop member 122b abuts against the corresponding suspension support 1112 in the vertical direction, and the centering member 122a abuts against the corresponding suspension support 1112 in the vertical and horizontal directions respectively.

[0038] In the motor mounting mechanism 120 of the aforementioned vehicle 100, the lower end of the centering groove 120a has an open structure, and the width of the openness of the centering groove 120a gradually decreases from the lower end to the upper end. This allows at least one centering member 122a to guide the corresponding mounting connector 1111 to be accommodated in the centering groove 120a when the motor mounting mechanism 120 is installed on the frame 110. This allows at least one centering member 122a to cooperate with the stop member 122b to guide the motor mounting mechanism 120 in the vertical direction, thereby reducing the debugging cycle. In addition, the stop member 122b can stop the corresponding mounting support 1112 in the vertical direction, reducing the excessive descent of the motor mounting mechanism 120 as a whole, thereby improving the assembly efficiency of the motor mounting mechanism 120 and the frame 110. Furthermore, when the housing 121 and the suspension member 111 are connected and fixed, the mounting surface 121a abuts against the corresponding suspension support 1112 in the front-rear direction, the stop member 122b abuts against the corresponding suspension support 1112 in the vertical direction, and the centering member 122a abuts against the corresponding suspension support 1112 in the vertical and horizontal directions respectively. This allows the centering member 122a and the stop member 122b, together with the suspension member 111, to limit the motor suspension mechanism 120 in the front-rear, horizontal, and vertical directions respectively. This reduces the swaying of the motor suspension mechanism 120 relative to the frame 110, thereby improving the connection stability between the motor suspension mechanism 120 and the frame 110, and ensuring the performance of the vehicle 100.

[0039] Please see Figure 3In some embodiments, the centering member 122a includes a limiting body 1221 and two guide bodies 1222. The limiting body 1221 is connected to the housing 121 and located above the mounting hole 121b. The two guide bodies 1222 are respectively connected to the housing 121 and located on the left and right sides of the limiting body 1221, with one end of each guide body 1222 connected to the limiting body 1221. The distance between the two guide bodies 1222 increases in the direction away from the limiting body 1221, and the two guide bodies 1222 are symmetrically arranged about the limiting body 1221. The two guide bodies 1222, the limiting body 1221, and the mounting surface 121a form a centering groove 120a.

[0040] The limiting body 1221 and the two guide bodies 1222 make the centering member 122a approximately trapezoidal in shape. The distance between the two guide bodies 1222 increases in the direction away from the limiting body 1221, which can guide the suspension support 1112 into the centering groove 120a in the vertical direction, thereby guiding the motor suspension mechanism 120 in the vertical direction and reducing the assembly error between the housing 121 and the suspension member 111. In addition, the two guide bodies 1222 are symmetrically arranged about the limiting body 1221, which can improve the uniformity of the guidance of the suspension support 1112 by the two guide bodies 1222, thereby improving the stability of the suspension support 1112 entering the centering groove 120a.

[0041] It should be noted that the limiting body 1221 and the stop 122b are at the same height in the vertical direction. The limiting body 1221 can limit the corresponding suspension support 1112 in the vertical direction, and plays the same limiting role as the stop 122b on the corresponding suspension support 1112.

[0042] In some embodiments, the centering member 122a includes two guide bodies 1222. The two guide bodies 1222 are respectively connected to the housing 121. One end of each guide body 1222 is connected to and located above the mounting hole 121b, while the other ends of each guide body 1222 are located away from each other and below the mounting hole 121b. The distance between the two guide bodies 1222 gradually increases in the direction away from the connection point of the two guide bodies 1222, and the two guide bodies 1222 are symmetrically arranged about the mounting hole 121b. The two guide bodies 1222 and the mounting surface 121a form a centering groove 120a.

[0043] The centering member 122a formed by the interconnection of two guide bodies 1222 has an approximately inverted V-shaped structure. Compared to the trapezoidal structure of the centering member 122a, the V-shaped structure can improve the centering accuracy of the corresponding suspension support 1112. The connection point of the two guide bodies 1222 is at the same height as the stop member 122b in the vertical direction. The connection point of the two guide bodies 1222 can limit the corresponding suspension support 1112 in the vertical direction, playing the same limiting role as the stop member 122b.

[0044] In some embodiments, the surface of each guide 1222 facing another guide 1222 is an arcuate surface or a plane.

[0045] For example, the surface of each guide 1222 facing another guide 1222 is an arc-shaped surface, which makes the force exerted by the guide 1222 on the suspension support 1112 more uniform, and can be applied to the motor suspension mechanism 120 with a large weight.

[0046] For example, the surface of each guide 1222 facing another guide 1222 is flat. The flat structure is easy to process and can reduce the manufacturing cost of the guide 1222.

[0047] Please see Figure 7 In some embodiments, each guide body 1222 includes a plurality of guide segments 1222a connected in sequence. Each guide segment 1222a is inclined relative to the axial direction of the mounting hole 121b, and the inclination rate of the guide segment 1222a gradually decreases along the opening direction away from the centering groove 120a.

[0048] By employing multiple guide segments 1222a with different slopes, the guide body 1222 can provide phased guidance to the suspension support 1112 in the vertical direction. The guide segment 1222a at the lower end has a larger slope, which can limit the suspension support 1112 in the vertical direction, while the guide segment 1222a at the upper end has a smaller slope, which can limit the suspension support 1112 in the horizontal direction. This facilitates the gradual conversion of the interaction force between the guide body 1222 and the suspension support 1112 in the vertical and horizontal directions, thereby reducing damage to the suspension support 1112 and the guide body 1222 caused by excessive force in one direction.

[0049] In some embodiments, the surface of the limiting body 1221 facing the corresponding mounting hole 121b and the surface of the stop member 122b facing the corresponding mounting hole 121b are both recessed structures to accommodate a portion of the suspension support 1112.

[0050] The groove structure described above can provide a radial limiting function for the suspension support 1112, thereby improving the stability of the suspension support 1112 in the vertical and horizontal directions.

[0051] In some embodiments, the limiting body 1221 and the stop 122b are elastic structures.

[0052] The elastic structure of the limiting body 1221 and the stop 122b can buffer the force of the suspension support 1112 in the vertical direction, reduce the surface damage caused by the collision of the suspension support 1112, the limiting body 1221 and the stop 122b, and help improve the service life of the suspension support 1112, the limiting body 1221 and the stop 122b.

[0053] In some embodiments, flexible structures are respectively attached to the surface of the limiting body 1221 facing the corresponding mounting hole 121b and the surface of the stop member 122b facing the corresponding mounting hole 121b.

[0054] The flexible structure can buffer the force exerted by the suspension support 1112 on the limiting body 1221 and the stop 122b in the vertical direction, reducing surface damage caused by collisions between the suspension support 1112, the limiting body 1221, and the stop 122b, thus improving their service life. Compared to the elastic structure of the limiting body 1221 and the stop 122b, the attached flexible structure facilitates replacement.

[0055] Please see Figure 3 and Figure 4 In some embodiments, the housing 121 also has a plurality of guide ramps 121c, which are respectively provided with a plurality of mounting surfaces 121a. Each guide ramp 121c is located below the corresponding mounting hole 121b and connected to the corresponding mounting surface 121a. The distance between each guide ramp 121c and the corresponding mounting surface 121a in the axial direction of the mounting hole 121b gradually increases in the direction away from the mounting hole 121b, so as to slide against the corresponding suspension support 1112.

[0056] Multiple guide ramps 121c can guide multiple suspension supports 1112 to gradually correspond one-to-one with multiple mounting surfaces 121a, reducing the assembly error between the housing 121 and the frame 110.

[0057] For example, there are four guide ramps 121c, with one guide ramp 121c at the lower end of each mounting surface 121a.

[0058] Here, taking the four suspension members 111, four mounting surfaces 121a, four connecting units 122 (one centering member 122a and three stop members 122b) and the centering member 122a including the limiting body 1221 and two guide bodies 1222 as examples, the assembly process of the above-mentioned motor suspension mechanism 120 with the frame 110 is roughly as follows: First, the suspension connectors 1111 of the four suspension components 111 are fastened to the corresponding installation positions on the frame 110 with bolts. The pre-installed motor suspension mechanism 120 is then lifted by a crane and moved above the frame 110, so that the four connecting units 122 on the housing 121 are roughly aligned with the corresponding four suspension components 111 on the frame 110.

[0059] Secondly, the housing 121 descends slowly under the influence of the crane. Due to the limited positioning accuracy of the crane, there may be a large initial deviation (typically several millimeters) between the connecting unit 122 on the housing 121 and the suspension member 111 on the frame 110 in the horizontal plane. During the slow descent of the housing 121, the guide ramp 121c located at the lower end of the housing 121 first approaches the suspension support 1112 of the suspension member 111. The guide ramp 121c provides sufficient tolerance window—even if the deviation is large, the outer circular surface of the suspension support 1112 can be captured by the guide ramp 121c. As the housing 121 continues to descend, the outer circular surface of the suspension support 1112 slides along the guide ramp 121c, and one of the suspension supports 1112 is gradually guided into the lower opening of the centering groove 120a of the centering member 122a. This stage realizes the transition from a "large deviation free state" to a "small deviation constrained state" between the housing 121 and the suspension member 111.

[0060] Then, the housing 121 continues to descend under its own weight and the lowering action of the crane. At this time, the two guide bodies 1222 of the centering member 122a begin to contact the outer circular surface of the suspension support 1112. As the distance between the two guide bodies 1222 gradually decreases in the upward direction, when the suspension support 1112 contacts the two guide bodies 1222 simultaneously, the gravity of the housing 121 is decomposed along the normal direction of the inclined plane, generating a horizontal component force pointing to the left and right. The horizontal component force in the left and right directions pushes the housing 121 as a whole to automatically translate and adjust within the plane formed by the front-back and left-right directions, so that the axis of symmetry of the two guide bodies 1222 gradually converges towards the axis of the suspension support 1112. As the housing 121 continues to descend, the positional deviations in the planes in the front-back and left-right directions are gradually eliminated until the two guide bodies 1222 and the outer circular surface of the suspension support 1112 reach a stable contact state. At this time, the mounting hole 121b on the mounting surface 121a and the inner hole of the suspension support 1112 are coaxially aligned.

[0061] Finally, when the housing 121 slides down to the designed depth via the two guide bodies 1222, the limiting body 1221 of the centering member 122a abuts against the corresponding suspension support 1112 in the vertical direction, and the stop member 122b abuts against the corresponding suspension support 1112 in the vertical direction to prevent the housing 121 from descending further. At this time, the end face of the suspension support 1112 fits against the mounting surface 121a on the housing 121 in the front-back direction, and the outer circular surface of the suspension support 1112 fits against the two guide bodies 1222 of the centering member 122a. The housing 121 is positioned relative to the suspension member 111 in the front-back, left-right, and vertical directions. Four locking bodies 1113 are inserted from one side of the suspension connector 1111, through the inner hole of the suspension support 1112, and screwed into the mounting hole 121b on the housing 121. The final locking is completed by tightening to the specified torque, so that the motor suspension mechanism 120 is stably and accurately installed on the frame 110.

[0062] It should be noted that after the four locking bodies 1113 are tightened, the four connecting units 122 reach the working state. At this time, the centering part 122a, which originally played a guiding role during the assembly stage, transforms into a bearing surface in the left-right and up-down directions, directly bearing the shear load generated by the working torque of the electric drive assembly and road impact. The contact surface between the stop part 122b and the suspension support 1112 transforms into a rigid bearing surface in the front-rear direction, and the mounting surface 121a bears the normal clamping force generated by the pre-tightening force of the locking body 1113, effectively suppressing the multi-directional vibration and fretting displacement of the motor suspension mechanism 120 of the vehicle 100 in the working state.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
