It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0029] Combine Figures 1 to 4 As shown, according to a specific embodiment of the present application, a suspended inner core is provided.

[0030] Specifically, a suspended inner core is used to connect to an engine, comprising: an inner core body 10, a limiting protrusion 20 is provided on the inner core body 10, the limiting protrusion 20 is extended along the circumference of the inner core body 10, and a stop table 21 is formed on the side of the limiting protrusion 20 facing the first end of the inner core body 10, and a second end of the inner core body 10 opposite to the first end forms a connecting end, and a guide structure 11 and a limiting surface 12 are also provided on the circumference of the first end of the inner core body 10, and the guide structure 11 and the limiting surface 12 are both located on the same side of the stop table 21, and the limiting surface 12 is arranged at an angle to the first direction and the second direction, wherein the first direction is the direction of travel of the vehicle, and the second direction is perpendicular to the first direction.

[0031] In this embodiment, a stop surface is formed by providing a limiting protrusion on the inner core body, and a guide structure and a limiting surface are provided at the first end of the inner core body. This allows the inner core to effectively guide and roughly position the inner core, and the limiting surface effectively ensures that the inner core is properly installed. This structure ensures that the installation process does not require other auxiliary tooling for positioning. The inner core itself can maintain accurate relative position, making assembly more convenient.

[0032] Furthermore, along the circumferential direction of the inner core body 10, the guide structure 11 includes a first guide surface 111, a second guide surface 112, a third guide surface 113, and a fourth guide surface 114 connected in sequence, wherein the limiting surface 12 is located between the first guide surface 111 and the fourth guide surface 114. The first guide surface 111, the second guide surface 112, the third guide surface 113, the fourth guide surface 114, and the limiting surface 12 are all connected to the stop table 21. This arrangement plays a guiding role and does not require other auxiliary tooling for positioning.

[0033] Specifically, a connection hole 121 is formed on the limiting surface 12, and the axis of the connection hole 121 is perpendicular to the limiting surface 12. In this embodiment, the limiting surface is provided with a connection hole 121 with a radius of 4mm and a depth of 5mm. A protrusion of the same size is provided on the limiting rubber sheet that cooperates with the connection hole 121. In this way, positioning is achieved through the recess and protrusion, ensuring assembly accuracy.

[0034] The inner core body 10 is a columnar structure. One side of the first guide surface 111 is connected to the limiting surface 12, and the other side of the first guide surface 111 is connected to the second guide surface 112. The height of the first guide surface 111 along the axial direction of the inner core body 10 is less than the height of the limiting surface 12 and the first guide surface 111 along the axial direction of the inner core body 10. The portion of the second guide surface 112 near the first end of the inner core body 10 is connected to the limiting surface 12. This arrangement can ensure the strength of the thread and improve the reliability of the connection.

[0035] The connection between the second guide surface 112, the third guide surface 113 and the fourth guide surface 114 is arranged in an arc shape, which avoids the wear of the inner core caused by angle friction during installation, and the arc surface plays a protective role.

[0036] The first guide surface 111 is perpendicular to the stop surface 21. This arrangement allows the bracket to be installed from top to bottom, with the inner core smaller at the top and larger at the bottom, effectively providing guidance and rough positioning. The red limiting surface effectively ensures proper installation. This structure eliminates the need for auxiliary tooling during installation, as the inner core itself maintains accurate relative positioning.

[0037] Furthermore, the angle between the second guide surface 112 and the stop surface 21 is β1, wherein 110°≤β1≤120°. The angle between the third guide surface 113 and the stop surface 21 is β2, wherein 95°≤β2≤105°. The angle between the fourth guide surface 114 and the stop surface 21 is β3, wherein 84°≤β3≤94°. In this embodiment, the angle of the guide surface for mounting needs to take into account the length of the thread. It is necessary to make the thread as long as possible on a limited structure to ensure the strength of the thread. It is recommended that each guide surface be designed according to the following angles, combined with Figure 1 and Figure 2 As shown, the angle between the second guide surface and the stop surface 21 is 115°. Figure 1 and Figure 3 As shown, the angle between the third guide surface and the stop surface 21 is 100°. Figure 1 and Figure 4 As shown, the angle between the fourth guide surface and the stop surface 21 is 89°. The angle is related to the arrangement of the inner core, and the specific angle value can be fine-tuned.

[0038] Furthermore, the inner core body 10 includes: a first component segment 100, wherein the first end of the first component segment 100 forms the mounting end, and the first component segment 100 is provided with a guide structure 11 and a limiting surface 12 in the circumferential direction; a second component segment 101, wherein a portion of the end surface of the first end of the second component segment 101 is connected to the second end of the first component segment 100, and another portion of the end surface of the first end of the second component segment 101 forms a stop table 21; and a third component segment 102, wherein the first end of the third component segment 102 is connected to the second end of the second component segment 101, and the second end of the third component segment 102 is provided with a limiting flange 103, the outer diameter of the limiting flange 103 being greater than the maximum outer diameter of the second component segment 101 and the third component segment 102. In this embodiment, the first component segment plays a good positioning role and does not require other auxiliary tooling for positioning, and the second component segment plays a supporting role to effectively ensure that it is installed in place.

[0039] Furthermore, a plurality of weight-reducing pits 1010 are axially arranged on the second component segment 101. The cross-sectional area from the first end of the third component segment 102 to the second end of the third component segment 102 is gradually increased. In this embodiment, the second component segment is designed with two rows of weight-reducing pits, which are approximately 4mm×5mm in size. There are two main functions of designing these pits. The first is lightweighting. These parts have very little stress when loaded. Removing the material from these parts will prevent damage caused by insufficient strength during use. The removal of these materials will reduce the weight of the parts themselves, thereby improving the fuel economy of the entire vehicle. The second is that for high-pressure cast aluminum alloys, the more uniform the thickness of the casting, the easier it is to ensure the casting quality. Digging some pits in the thicker part in the middle of the inner core can achieve uniform thickness, thereby ensuring the quality of the casting. The third component segment is provided with a conical surface, which is small at the top and large at the bottom. The design here is to achieve guidance when assembling the inner limit plate, ensuring that the inner limit plate can be smoothly pressed into place from top to bottom.

[0040] In another embodiment of the present application, a vehicle is provided, comprising a suspension core connected to an engine via a bracket, wherein the suspension core is the suspension core described above. Figure 1 As shown, the X direction is the direction of vehicle travel and the direction of front and rear collisions, which results in higher loads. The mounting surface is set at angles α and β with the X and Y directions, avoiding alignment in any particular direction. This prevents the load from being completely balanced by friction on the mounting surface, cleverly improving connection reliability and ensuring reliable connections under high loads. Because the mounting surface is highly capable of withstanding positive pressure but relatively weak against friction, friction is affected by the axial force of the bolt and the friction coefficient of the mounting surface, making it difficult to increase. This angled design prevents friction from bearing the load entirely in any particular direction, ensuring a reliable connection without increasing bolt capacity.

[0041] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0042] In addition to the above, it should be noted that references to "one embodiment," "another embodiment," "an embodiment," and the like in this specification refer to specific features, structures, or characteristics described in conjunction with that embodiment as included in at least one embodiment generally described in this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in conjunction with any embodiment, it is intended that such feature, structure, or characteristic, when implemented in conjunction with other embodiments, also falls within the scope of the present invention.

[0043] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0044] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
