Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a suspension anti-rotation structure. Meanwhile, the utility model also relates to a vehicle provided with the suspension anti-rotation structure. Background Art

[0002] Due to the exhaust pollution of traditional fuel vehicles, various automakers have been focusing on promoting pure electric vehicles in recent years. The suspension structure and layout of the powertrain of pure electric vehicles are quite different from those of traditional models. The inner core of the suspension generally has one or two connection points with the motor assembly, which are connected to the motor assembly by bolts. When there is only one mounting point between the inner core and the motor assembly, during the assembly of the bolts, the friction between the bolts and the inner core causes the inner core to deflect, causing the main spring to deflect with the inner core, which will affect the suspension performance and cause the vehicle's NVH (Noise, Vibration, Harshness) or handling stability performance to deteriorate. Utility Model Content

[0011] The limiting portion includes a limiting ring arranged in the installation groove, the column is slidably inserted in the limiting ring, and the limiting ring abuts against the blocking piece, which can limit the positioning member from escaping from the installation groove.

[0012] Furthermore, the limiting ring is interference-inserted in the mounting groove.

[0013] Furthermore, a limiting plane is provided on the positioning member, and a matching plane abutting against the limiting plane is provided in the positioning groove.

[0014] Furthermore, the limiting planes are provided on two opposite sides of the positioning member, and the matching planes are arranged in a one-to-one correspondence with the limiting planes.

[0015] Furthermore, the positioning member is provided with a guide surface, and the inner core and the connecting member are in contact with the guide surface, so as to drive the positioning member to slide to a side away from the positioning groove.

[0016] Furthermore, the connecting piece is provided with a connecting hole and a connecting portion;

[0017] The connecting hole is used to be connected to the inner core, and when the positioning member is inserted into the positioning groove, the connecting hole is aligned with the axial hole of the inner core, and the connecting portion is used to be connected to the power assembly.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] The suspension anti-rotation structure described in the utility model is characterized by providing a positioning groove on one of the inner core and the connecting piece, and providing a positioning portion including a positioning piece and an elastic piece on the other of the two. The positioning piece can be inserted into the positioning groove, and when the inner core is connected to the connecting piece, the rotation of the inner core relative to the connecting piece can be restricted, thereby better ensuring the working performance of the suspension; at the same time, when the connecting piece and the inner core are disassembled, the positioning piece can be squeezed to retract as the connecting piece slides relative to the inner core, thereby facilitating the disassembly and assembly between the connecting piece and the inner core.

[0020] In addition, by providing the mounting groove, it is convenient to arrange the positioning member and the elastic member on the inner core or the connecting member.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] In addition, in the description of the present invention, unless otherwise clearly defined, the terms "installation", "connection", "connection", and "connector" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0043] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0044] This embodiment relates to a suspension anti-rotation structure, which is arranged between the suspension 1 and the connecting member 2 adapted to the suspension 1, and includes a positioning portion arranged on one of the inner core 101 of the suspension 1 and the connecting member 2, and a positioning groove 201 arranged on the other of the inner core 101 and the connecting member 2. The positioning portion includes a positioning member 4 and an elastic member, and the elastic member can push the positioning member 4 to be inserted into the positioning groove 201, so as to limit the rotation of the inner core 101 relative to the connecting member 2.

[0045] The suspension anti-rotation structure of this embodiment is provided with a positioning groove 201 on one of the inner core 101 and the connecting member 2, and a positioning part including a positioning member 4 and an elastic member is provided on the other of the two. The positioning member 4 can be inserted into the positioning groove 201, and when the inner core 101 is connected to the connecting member 2, the inner core 101 can be restricted from rotating relative to the connecting member 2, thereby better ensuring the working performance of the suspension 1. At the same time, when the connecting member 2 and the inner core 101 are disassembled, as the connecting member 2 slides relative to the inner core 101, the positioning member 4 can be squeezed to retract, thereby facilitating the disassembly and assembly between the connecting member 2 and the inner core 101.

[0046] Based on the above design concept, an exemplary structure of the suspension anti-rotation structure of this embodiment is referred to as Figure 1 and Figure 2 As shown in , the structure of the suspension 1 is the same as that of the prior art, and it also includes an outer tube 103, an inner core 101 arranged in the outer tube 103, and a rubber body 102 connecting the outer tube 103 and the inner core 101. As a preferred embodiment, Figure 3 As shown in the figure, the positioning groove 201 of this embodiment is provided on the connecting member 2, and the positioning portion is provided on the inner core 101 of the suspension 1. It can be understood that in a specific implementation, the positioning groove 201 can also be provided on the inner core 101, and the positioning portion can be provided on the connecting member 2.

[0047] The connecting member 2 may be a bracket for connecting to a motor or an engine, which may be the motor or the engine itself. Figure 1 As shown in the figure, this embodiment is described by taking the connecting member 2 as a bracket for connecting with a motor or an engine as an example. Specifically, the connecting member 2 is provided with a connecting hole and a connecting portion, and the connecting hole is used to connect with the inner core 101, and when the positioning member 4 is inserted into the positioning groove 201, the connecting hole is aligned with the shaft hole 1011 of the inner core 101, and the connecting portion is used to connect with the power assembly.

[0048] The above arrangement facilitates the alignment of the axial hole 1011 of the inner core 101 with the connecting hole, which is beneficial to improving the connection efficiency between the inner core 101 and the connecting member 2. In addition, the connecting portion of the present embodiment is specifically a through hole provided on the connecting member 2, so as to be connected to a power assembly such as a motor through a bolt 3 passing through the through hole. It should be mentioned that the specific structure of the connecting member 2 and the number of through holes are not specifically limited in the present embodiment, and can be designed according to design requirements. In addition, in addition to being a through hole provided on the connecting member 2, the connecting portion can also be a threaded hole or a bolt 3 provided on the connecting member 2.

[0049] Based on the positioning portion being arranged on the inner core 101, as a preferred embodiment, Figures 4 to 6 As shown in FIG. 1 , the inner core 101 is provided with a mounting groove. Moreover, since the connecting member 2 is generally assembled with the suspension 1 along the radial direction of the suspension 1 (i.e. Figure 1 1011). Therefore, the mounting groove of the present embodiment is provided on the end surface of one axial end of the inner core 101 and is located on one side of the shaft hole 1011. In addition, the positioning member 4 is slidably provided in the mounting groove along the axial direction of the inner core 101, and the elastic member is provided in the mounting groove and is provided between the positioning member 4 and the inner core 101. In the present embodiment, by providing the mounting groove, it is convenient to provide the positioning member 4 and the elastic member on the inner core 101 or the connecting member 2.

[0050] As a specific embodiment, the elastic member is specifically a spring 5 arranged in the installation groove. At this time, in order to improve the setting stability of the spring 5, as shown in FIG. Figure 6 As shown in , a pit is provided at the bottom of the installation groove, one end of the spring 5 is arranged in the pit, and the other end is sleeved on the positioning member 4. In addition, in order to better ensure the anti-rotation function, as a further embodiment, a limiting portion is provided in the installation groove, and the limiting portion is used to limit the positioning member 4 from escaping from the installation groove.

[0051] As a preferred embodiment, Figure 6 As shown in , the positioning member 4 includes a column 401 and a baffle 402 protruding radially outward along the column 401. At the same time, the limiting portion includes a limiting ring 6 arranged in the installation groove, and the column 401 is slidably inserted in the limiting ring 6. The limiting ring 6 abuts against the baffle 402, which can limit the positioning member 4 from falling out of the installation groove. This structure can not only improve the sliding smoothness of the positioning member 4 by utilizing the sliding abutment between the limiting ring 6 and the column 401, but also facilitate design and implementation. In this embodiment, in order to facilitate processing and manufacturing, as a preferred embodiment, as shown in FIG. Figure 6 As shown in , the limiting ring 6 is inserted into the installation groove with interference fit.

[0052] It should be noted that the limiting ring 6 can be welded or bonded in the installation groove in addition to being set in the installation groove with interference fit. Figure 8The structure shown in the prior art can also adopt the retaining spring. In this case, a retaining groove can be set on the groove wall of the installation groove, and the retaining spring can be clamped in the retaining groove.

[0053] In addition, it is worth noting that, in addition to abutting the spring 5 between the inner core 101 and the positioning member 4 and setting a limiter, the two ends of the spring 5 can also be connected to the inner core 101 and the positioning member 4 respectively. In this case, it is not necessary to set a limiter and a baffle 402 according to needs, and the outer peripheral surface of the positioning member 4 is slidably abutted with the installation groove, which can also play a good guiding effect. In addition, in addition to setting the installation groove on the end surface of the inner core 101, the installation groove can also be set on the outer peripheral surface of the inner core 101 according to the assembly direction of the connecting member 2.

[0054] Combination Figure 7 and Fig. 9 As shown in , as a preferred embodiment, a limiting plane M is provided on the positioning member 4, and a matching plane P is provided in the positioning groove 201 to abut against the limiting plane M. Such an arrangement can better prevent the inner core 101 and the connecting member 2 from rotating relative to each other. As a further embodiment, limiting planes M are provided on both opposite sides of the positioning member 4, and the matching planes P are arranged one-to-one with the limiting planes M. Thus, the rotation of the inner core 101 can be better limited by the abutment of the limiting planes M on both sides with the matching planes P on the corresponding side.

[0055] At this time, in order to facilitate the insertion of the positioning member 4 into the positioning groove 201, the arrangement direction of the two limiting planes M is perpendicular to the assembly direction of the connecting member 2 to prevent the limiting planes M from abutting against the connecting member 2, which would have a large resistance and be unfavorable for the positioning member 4 to be retracted into the installation groove. Figure 7 As shown in , as a further embodiment, a guide surface N is provided on the positioning member 4, and the guide surface N of the connecting member 2 abuts against it, which can drive the positioning member 4 to slide to the side away from the positioning groove 201, that is, to slide into the installation groove.

[0056] Among them, Figure 7 As shown in , the guide surface N is disposed between the two limiting planes M and is specifically a smooth arc surface to minimize the friction between it and the connecting member 2. As a further embodiment, Figure 7 As shown in , the guide surface N extends from one side of the positioning member 4 to the opposite side, thereby further facilitating the connector 2 to push the guide surface N and drive the positioning member 4 to retract into the installation groove.

[0057] It should be noted that, in addition to setting the limiting plane M on the positioning member 4, the limiting plane M may not be set. That is, in this case, the column 401 is cylindrical, but a plurality of positioning members 4 are arranged at intervals and inserted into the corresponding positioning grooves 201. This structure can also limit the rotation of the inner core 101 relative to the connecting member 2.

[0058] Based on the above introduction, in specific applications, first press the suspension 1 onto the subframe, and then Figure 1 The inner core 101 and the connector 2 are moved from bottom to top in the state. Moreover, as the connector 2 moves, the connector 2 first contacts the guide surface N of the positioning member 4, and the positioning member 4 can be pushed into the installation groove. When the positioning groove 201 hole of the connector 2 moves to the positioning member 4, the spring 5 pushes the positioning pin into the positioning groove 201, thereby fixing the positioning member 4 and the positioning groove 201, thereby limiting the relative movement of the inner core 101 and the connector 2. Moreover, at this time, the connecting hole of the connector 2 and the axial hole 1011 of the inner core 101 are in the aligned position. Finally, the inner core 101 and the connector 2 can be connected by the bolt 3.

[0059] The suspension anti-rotation structure of this embodiment, by adopting the above structure, can not only limit the relative rotation between the inner core 101 and the connecting member 2, but also the positioning member 4 can be retracted into the installation groove after being compressed, therefore, it does not affect the lifting process of the power assembly.

[0060] In addition, the present embodiment also relates to a vehicle, on which the above suspension anti-rotation structure is provided.

[0061] The vehicle of this embodiment has all the beneficial effects of the above-mentioned suspension anti-rotation structure, which will not be described in detail here.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
