According to the utility model discloses power assembly system of first aspect embodiment, including engine 500, suspension support 400, two reference columns 200, compress tightly piece 300 and connecting axle 100.
Wherein, the suspension bracket 400 is provided with two fastening holes 410. The positioning columns 200 correspond to the fastening holes 410 one by one, the positioning columns 200 are arranged in the fastening holes 410 in a penetrating manner, one ends of the positioning columns 200 are connected to the engine 500, and the other ends of the positioning columns 200 are provided with first through holes 210 exposed outside the fastening holes 410. The pressing member 300 is disposed between the two positioning pillars 200, the pressing member 300 includes a pressing portion 310, a second through hole 311 is disposed on the pressing portion 310, and the pressing portion 310 includes a distal end 312. The connecting shaft 100 is disposed through the second through hole 311 and the first through holes 210 of the two positioning pillars 200. The pressing member 300 can rotate about the axis of the connecting shaft 100 with respect to the positioning column 200, and the distal end 312 rotated to a predetermined position can press the suspension bracket 400 against the motor 500.
Specifically, the positioning column 200 is cylindrical, one end of the positioning column is tapped with an external thread capable of being in threaded fit with a threaded hole formed in the surface of the engine 500, the other end of the positioning column is provided with a first through hole 210, and the connecting shaft 100, which is also cylindrical, can pass through the first through hole 210 just or with a gap. Two fastening holes 410 are formed in the suspension bracket 400 to be pressed against the engine 500, and the fastening holes 410 are through holes, so that one end of the positioning column 200, which is in one-to-one correspondence with the fastening holes 410 and is provided with external threads, can pass through the fastening holes 410 and be in threaded connection with the engine 500.
The pressing member 300 includes a pressing portion 310. The pressing portion 310 has a columnar shape, and a second through hole 311 through which the connection shaft 100 can pass is provided in a bottom surface thereof. At this time, one end of the connecting shaft 100 is inserted into the first through hole 210 of one positioning column 200, the other end is inserted into the first through hole 210 of the other positioning column 200, and the middle portion of the connecting shaft 100 is inserted into the second through hole 311. It is understood that, under the action of external force, the pressing member 300 can rotate relative to the positioning column 200 about the central axis of the connecting shaft 100 as a rotating shaft. The pressing portion 310 is provided with a distal end 312 in the rotation direction, and the outward side of the distal end 312 may be a curved surface or a joint of a curved surface and a flat surface. In this case, the bottom surface of the pressing portion 310 may be an oval shape, an isosceles trapezoid with the side edges being arc lines protruding outward, or the like. Meanwhile, the maximum distance of the distal end 312 from the coupling shaft 100 is smaller than the distance between the coupling shaft 100 and the side of the suspension bracket 400 facing the pressing member 300.
It will be appreciated that when the rotated distal end 312 is rotated to a predetermined position, the distal end 312 will abut against the side of the suspension bracket 400 facing the compression member 300 and apply a force to the suspension bracket 400 facing the engine 500, thereby compressing the suspension bracket 400 against the engine 500. The preset position is a position where the pressing portion 310 is located when a connection line between a point on the side surface of the pressing portion 310 provided with the second through hole 311, which is farthest from the center of the second through hole 311, and the center of the second through hole 311 on the edge of the side surface is parallel to the central axis of the positioning column 200. Meanwhile, also on the side of the pressing part 310 where the second through hole 311 is provided, the shortest distance from the edge of the side to the center of the second through hole 311 is less than or equal to the shortest distance between the central axis of the connecting shaft 100 and the side of the suspension bracket 400 facing the engine 500, so that the pressing part 310 can freely rotate within a certain range.
It can be understood that, in actual use, when the suspension bracket 400 needs to be compressed, the position of the distal end 312 only needs to be adjusted to a preset position; when the suspension bracket 400 needs to be detached, the connecting shaft 100 and the pressing piece 300 are detached from the positioning column 200 in sequence, and then the suspension bracket 400 is taken out from the positioning column 200. The design does not need to use additional auxiliary tools, is convenient to operate, effectively shortens the assembly and unloading efficiency, shortens the working hours and further reduces the cost.
In some embodiments of the present invention, the device further includes a power assisting portion 320, one end of the power assisting portion 320 is fixed to the pressing portion 310, and the other end of the power assisting portion 320 extends in a direction away from the pressing portion 310.
Specifically, the pressing member 300 further includes a force-assisting portion 320. The assisting portion 320 is in the shape of a strip, one end of which is fixed to the compressing portion 310 by integral molding or welding, and the other end of which extends away from the compressing portion 310. It is understood that, in actual use, when the suspension bracket 400 needs to be compressed, the compressing portion 310 is rotated by the boosting portion 320 only by applying a force to the boosting portion 320, so as to rotate the position of the distal end 312 to a preset position. The power assisting part 320 utilizes the principle of labor-saving lever, so that the adjustment of the position of the far end 312 is easier and more convenient, and the efficiency is further improved.
In some embodiments of the present invention, the pressing surface 313 is disposed on the rotation periphery of the pressing portion 310, the pressing surface 313 rotated to the predetermined position is used for supporting the suspension bracket 400, and the surface of the suspension bracket 400 supported by the pressing surface 313 is a plane.
Specifically, the pressing surface 313 is a surface on which the distal end 312 abuts against the suspension bracket 400 when the distal end 312 is rotated to a predetermined position. The pressing surface 313 is planar, and it can be understood that the area of the pressing surface 313 is small enough, so that the distance from the edge of the pressing surface 313 to the axis of the second through hole 311 does not differ too much from the distance from the center line of the pressing surface 313 to the axis of the second through hole 311, and it is ensured that the chamfer does not have too great an influence on the rotating pressing part 310 to the preset position.
Meanwhile, the surface of the suspension bracket 400 abutting against the pressing surface 313 is a smooth plane, and the design of the pressing surface 313 replaces the linear contact with the surface contact compared with the arc-shaped distal end 312, thereby effectively avoiding the occurrence of the rebound of the pressing part 310.
In some embodiments of the present invention, the end of the compressing portion 310 away from the compressing surface 313 is provided with a fool-proof groove 314.
Specifically, the shape of the pressing portion 310 tends to be symmetrical, and after the pressing surface 313 is provided on the distal end 312, in order to ensure that the distal end 312 provided with the pressing surface 313 is adjusted to a preset position each time the position of the pressing portion 310 is adjusted, the fool-proof groove 314 is provided at the end of the pressing portion 310 where the pressing surface 313 is not provided. The fool-proof groove 314 is a striking groove, thereby effectively distinguishing the pressing portion 310 that should be used to press the suspension bracket 400, and improving the correct assembly efficiency.
In some embodiments of the present invention, the ratio of the narrowest width to the longest width of the side of the compressing part 310 provided with the second through hole 311 ranges from 0.4 to 0.6.
Specifically, on the bottom surface of the pressing portion 310 where the second through hole 311 is disposed, a line segment passing through the center of the second through hole 311 and finally meeting to the other end of the bottom surface edge is made with any point on the bottom surface edge as an end point, and the length of the line segment indicates the width of the side surface of the pressing portion 310. As shown in fig. 3, a represents the length of the narrowest width of the side surface, and b represents the length of the longest width of the side surface, where a: b ranges between 0.4 and 0.6.
When a: b is greater than 0.6, the pressing part 310 occupies a larger space on the premise of ensuring that the pressing part 310 can apply a sufficiently large pressing force to the suspension bracket 400; and when a: when b is less than 0.4, the strength of the pressing portion 310 is too low, and bending is likely to occur.
For example, when the pressing portion 310 is an elliptical cylinder, the bottom surface thereof provided with the second through hole 311 is an elliptical surface, and the narrowest width of the bottom surface is the minor axis length of the bottom surface, and the longest width is the major axis length of the bottom surface. The length of major axis can be twice as long as the length of minor axis this moment to when making compressing tightly portion 310 can not occupy too much space, guaranteed compressing tightly portion 310 and rotated to preset the position, compressing tightly portion 310 can exert enough big pressure to suspension support 400, and has enough intensity, has effectively avoided appearing buckling in the use.
In some embodiments of the invention, the side is oval.
Specifically, the pressing portion 310 is an elliptical cylinder, and the bottom surface thereof provided with the second through hole 311 is an elliptical surface. It will be appreciated that the oval design provides a smoother process of compressing the suspension bracket 400 by the compression portion 310.
In some embodiments of the present invention, the surface of the pressing portion 310 rotated to the predetermined position and supported by the suspension bracket 400 is a curved surface, and the surface of the suspension bracket 400 supported by the pressing portion 310 is a plane.
Specifically, the surface of the pressing portion 310 capable of abutting against the suspension bracket 400 is a curved surface, and accordingly, when the distal end 312 rotates to the preset position, the surface of the suspension bracket 400 abutting against the distal end 312 is a smooth plane. It will be appreciated that such a design allows for a smoother compression of the distal end 312 and reduces the spring back of the compression portion 310 as compared to a design in which the surface of the suspension bracket 400 that abuts the distal end 312 is curved.
In some embodiments of the present invention, the connecting shaft 100 is inserted into the second through hole 311 with interference.
Specifically, the diameter of each position of the connecting shaft 100 in the shape of a cylinder is equal and slightly larger than the diameter of the second through hole 311, so that the connecting shaft 100 inserted into the second through hole 311 is fitted with the second through hole 311 in an interference manner. It can be understood that the interference fit prevents the pressing member 300 from freely moving relative to the connecting shaft 100 in a direction parallel to the central axis of the connecting shaft 100, thereby ensuring that the pressing member 300 does not touch the positioning posts 200 on two sides of the pressing member during rotation, and prolonging the service life of the pressing member 300.
As an improvement to the above, the pressing member 300 clamped on the connecting shaft 100 by the second through hole 311 is disposed in the middle of the connecting shaft 100, that is, the distance from the center of the pressing member 300 to the positioning columns 200 on both sides is equal. It can be understood that, in practical use, the pressing member 300 has substantially the same magnitude of acting force on the two positioning pillars 200 through the connecting shaft 100, and even if a large acting force needs to be applied to the pressing member 300 to change the position of the pressing portion 310 in some cases, the two positioning pillars 200 will not be damaged.
In some embodiments of the utility model, still include the anticreep piece, the both ends of connecting axle 100 are provided with the anticreep hole, and the minimum distance between the anticreep hole is greater than the maximum distance between two reference columns 200, and the anticreep hole is worn to locate by the anticreep piece.
Specifically, the length of the connecting shaft 100 sequentially passing through the first through hole 210 of the first positioning column 200, the second through hole 311 of the pressing portion 310, and the first through hole 210 of the second positioning column 200 is greater than the distance from the side of the first positioning column 200 away from the second positioning column 200 to the side of the second positioning column 200 away from the first positioning column 200. Therefore, when the positioning posts 200 are inserted into the first through holes 210 and the second through holes 311 of the pressing portions 310, the connecting shaft 100 can have one end extending from the side of the first positioning post 200 away from the second positioning post 200 and the other end extending from the side of the second positioning post 200 away from the first positioning post 200, and two anti-falling holes are respectively formed at the two ends.
The anticreep hole is the through-hole, and anticreep piece can pass in the anticreep hole. The anti-dropping element can be a flexible iron wire, a stud or the like. When the anti-dropping holes at the two ends are provided with the anti-dropping parts, the anti-dropping parts can effectively prevent the connecting shaft 100 from moving greatly along the direction parallel to the central axis of the connecting shaft, so that the connecting shaft 100 cannot be separated from any first through hole 210, the connecting shaft 100 is always in the working position when the suspension bracket 400 is not compressed, and the compressing part 300 can be used at any time.
According to the utility model discloses car of second aspect embodiment, include according to the utility model discloses the power assembly system of above-mentioned first aspect embodiment.
Particularly, by adopting the power assembly system, the assembly time of the power assembly in the automobile is effectively shortened, the assembly efficiency is improved, and the cost is reduced.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
