Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts, in particular to a mounting assembly. At the same time, the utility model also relates to a vehicle provided with the mounting assembly. Background Art

[0002] As an important connecting component between the powertrain and the vehicle frame, the mounting is often integrally designed with the vehicle frame. The mounting bracket is often first assembled on the motor and assembled with the mounting bushing through connecting bolts. When assembling such a mounting, the mounting bracket and the motor are often pre-assembled into a motor assembly first, and the mounting bushing is press-fitted inside the vehicle frame through a sub-assembly line, and then the motor assembly and the vehicle frame are assembled together. When assembling, first fix the vehicle frame with the press-fitted mounting bushing on the tooling, then lift the motor assembly by a lifting device, move it to the upper end of the vehicle frame, and adaptively adjust the position of the motor.

[0003] At this time, first preliminarily align the mounting bushing and the mounting bracket in the X and Y directions of the whole vehicle, and then slowly lower the motor assembly in the Z direction. During the lowering process, further adjust the position of the motor in the X direction to ensure that the mounting surface of the mounting bracket is in contact with the mounting surface of the inner core of the mounting bushing in the X direction. Continue to lower until the two holes are also completely aligned in the Z direction; finally, pass the connecting bolt through the central hole of the mounting bushing and the mounting hole of the mounting bracket, tighten the torque, and the assembly is completed.

[0004] However, in order to facilitate the adjustment of the attitude and position of the motor assembly during the assembly of the motor and the vehicle frame, the motor can still rotate and move after being lifted. This setting also makes it difficult to control the accurate movement amount of the motor in the X, Y, and Z directions respectively during the assembly between the motor assembly and the vehicle frame, making it difficult to align the central hole of the bushing and the mounting hole of the mounting bracket, and the assembly is relatively difficult. The current main solution is for the assembler to manually control. During assembly, the position of the motor needs to be manually and accurately controlled in the X, Y, and Z directions respectively, which requires a high level of operation proficiency of the assembler and has a low assembly efficiency.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood in combination with specific situations.

[0046] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0047] This embodiment relates to a mounting assembly. In terms of the overall composition, it includes a bushing 1 and a mounting bracket 2 connected to the bushing 1, and a positioning and guiding portion for guiding the connection between the bushing 1 and the mounting bracket 2 is provided therebetween.

[0048] Among them, the positioning and guiding portion includes a first guiding unit that guides along a preset direction. The first guiding unit includes a first guiding block 201 provided on the mounting bracket 2 and a guiding groove K provided on the bushing 1 and matching the lower part of the first guiding block 201, and the notch of the guiding groove K is arranged upward along the up-down direction of the whole vehicle. The guiding groove K is located on the inner core 101 of the bushing 1 and on the end face of one end of the inner core 101, and in the up-down direction of the whole vehicle, the guiding groove K is located below the central hole 1011 of the inner core 101.

[0049] For the mounting assembly of this embodiment, by providing a positioning and guiding portion between the bushing 1 and the mounting bracket 2, it is beneficial to quickly position the mounting bracket 2 to the assembly position, thereby improving the connection efficiency between the two. Additionally, by arranging the guiding groove K on the inner core 101 of the bushing 1 and below the central hole 1011 of the inner core 101, when the first guiding block 201 of the mounting bracket 2 is inserted into the guiding groove K, the mounting bracket 2 can effectively abut against the inner core 101 of the bushing 1, thus effectively preventing the inner core 101 from rotating downward under the downward pressure of the mounting bracket 2, which is beneficial to the accurate positioning between the mounting bracket 2 and the bushing 1 and conducive to ensuring the connection efficiency between the two.

[0050] Based on the above overall introduction, an exemplary structure of the mounting assembly of this embodiment is as Figure 1 shown in the figure. In specific applications, the bushing 1 is usually pre-pressed on the subframe, and the mounting bracket 2 is used to connect to the powertrain. After separate assembly, the mounting bracket 2 and the bushing 1 are then connected together. Additionally, generally, the preset direction can be consistent with the left-right direction of the vehicle, and the axial direction of the following bushing can be consistent with the front-rear direction of the vehicle.

[0051] In addition, as a specific embodiment, as Figures 2 to 4 shown in the figure, the overall structure of the bushing 1 of this embodiment is the same as that of the prior art, and includes an inner core 101, an outer tube 103 sleeved outside the inner core 101, and a rubber body 102 vulcanized between the inner core 101 and the outer tube 103. Moreover, both ends of the inner core 101 protrude relative to the outer tube 103 and the rubber body 102 for connecting to the mounting bracket 2. A preferred embodiment of the mounting bracket 2 is as Figures 5 to 8 shown in the figure, and its overall shape is a flat block structure.

[0052] In addition, as a preferred embodiment, as Figure 5 and Figure 6 shown in the figure, the first guiding block 201 protrudes towards one side of the mounting bracket 2, that is, towards the side close to the bushing 1. And the end face of the first guiding block 201 abuts against the end face of the inner core 101. At the same time, a mating hole 205 is provided on the first guiding block 201 and is arranged to match the central hole 1011 of the inner core 101. The mounting bracket 2 and the inner core 101 are connected by a connecting member passing through the central hole 1011 and the mating hole 205. Among them, as a specific embodiment, the mating hole 205 is specifically a threaded hole provided on the mounting bracket 2, and the connecting member can specifically be a bolt passing through the central hole 1011. Of course, in addition to using bolts, it is also feasible to use a pin with an interference fit with the mating hole 205 as the connecting member.

[0053] In addition, as a preferred embodiment, the suspension bracket 2 is provided with a first connection portion and a second connection portion. The first connection portion is used to connect with the powertrain in the up-and-down direction of the whole vehicle, and the second connection portion is used to connect with the powertrain along the axial direction of the inner core 101. With such a design, it can be connected with the powertrain in two directions simultaneously, which can improve the connection firmness between the two. Among them, combined with Figures 5 to 8 As shown in [reference], as a specific embodiment, the first connection portion includes three first connection holes 204 spaced apart on the suspension bracket 2. And the second connection portion includes a connection block protruding from one side of the suspension bracket 2 along a preset direction, and a second connection hole 206 provided on the connection block.

[0054] Here, it can be understood that the first connection portion may include two, four or other numbers of first connection holes 204 in addition to three first connection holes 204. Similarly, the number of the second connection holes 206 can also be adjusted accordingly according to needs. In addition, in addition to adopting the form of connection holes, it is also feasible for the first connection portion and the second connection portion to adopt the structure of connection columns.

[0055] In addition, as a further embodiment, along the up-and-down direction of the whole vehicle from bottom to top, the width of the guide groove K gradually increases. Correspondingly, the two opposite sides of the lower part of the first guide block 201 are respectively inclined surfaces 207 arranged to match the guide groove K. In this embodiment, setting the width of the guide groove K to gradually increase along the up-and-down direction of the whole vehicle not only facilitates the quick insertion of the first guide block 201 into the guide groove K, but also can play a certain positioning effect on the suspension bracket 2 in the up-and-down direction of the whole vehicle after the two are inserted in place, which helps to further improve the connection efficiency between the suspension bracket 2 and the bushing 1.

[0056] Here, it needs to be explained that because the width of the guide groove K gradually increases, the two side walls of the guide groove K are inclined surfaces. This matching setting means that the inclined angles of the inclined surfaces 207 on the two opposite sides of the lower part of the first guide block 201 are the same as those of the side walls of the guide groove K, and they are formed in a conforming manner and can be abutted to guide the quick positioning of the suspension bracket 2 in the preset direction.

[0057] At this time, as a preferred embodiment, two convex blocks 104 are provided on the end surface of at least one end of the inner core 101. The two convex blocks 104 protrude along the axial direction of the inner core 101, and the above-mentioned guide groove K is formed by enclosing the two convex blocks 104. In this embodiment, by providing two convex blocks 104 on the end surface of the inner core 101 and making the guide groove K formed by enclosing the two convex blocks 104, the structure is simple and convenient for design and implementation. It should be noted that the guide groove K may be formed by only one convex block 104 in addition to being composed of two separately arranged convex blocks 104, that is, the bottom of the guide groove K is blocked at this time.

[0058] And combined with Figures 2 to 4As shown in the figure, in this embodiment, on the premise that the bushing 1 can be connected to the mounting bracket 2, in order to reduce the processing cost, the convex block 104 is only provided at one end of the inner core 101. Obviously, it is also feasible to provide the convex block 104 at the other end of the inner core 101. In addition, as a further implementation method, for the convenience of processing and manufacturing, the two convex blocks 104 are symmetrically arranged with respect to the central plane of the inner core 101, that is, the guiding groove K is located in the middle of the inner core 101 in the radial direction. In addition, as a specific embodiment, the width difference between the bottom end and the top end of the guiding groove K is between 8 mm and 10 mm, that is, when the deviation of the mounting bracket 2 and the bushing 1 in the preset direction is 8 mm - 10 mm, the mounting bracket 2 can be guided to be pre-installed in place, and good guiding ability can be achieved.

[0059] In addition, it should be mentioned that when the guiding groove K is provided above the central hole 1011 and also on the upper part of the inner core 101, when the first guiding block 201 is inserted into the guiding groove K, due to the elasticity of the rubber body 102, the inner core 101 and the mounting bracket 2 tend to rotate and separate, so it is not conducive to the accurate positioning between the mounting bracket 2 and the bushing 1. For this reason, in this embodiment, the guiding groove K is particularly provided below the central hole 1011, and, as Figure 3 shown in the figure, as a preferred embodiment, the guiding groove K is provided at the bottom end of the inner core 101.

[0060] As a further implementation method, the positioning and guiding part includes a positioning unit for positioning the mounting bracket 2 in the up and down direction of the whole vehicle. The positioning unit includes a positioning surface 105 provided on the convex block 104 and a matching surface 202 provided on the first guiding block 201 that matches the positioning surface 105. And the above-mentioned preset direction, the up and down direction of the whole vehicle and the axial direction of the inner core 101 are perpendicular to each other in pairs.

[0061] By setting the positioning unit, it is beneficial to quickly position the relative position between the mounting bracket 2 and the bushing 1 in the up and down direction of the whole vehicle, and can further improve the connection efficiency between the two. The positioning unit includes a positioning surface 105 provided on the convex block 104 and a matching surface 202 provided on the first guiding block 201, and the structure is simple and convenient for design and implementation.

[0062] Among them, as a preferred embodiment, as Figure 2 and Figure 3 shown in the figure, the positioning surface 105 is located above the guiding groove K and is connected to the groove wall of the guiding groove K. And along the direction from bottom to top of the whole vehicle, the positioning surface 105 inclines towards the outside of the inner core 101. With such a design, after the mounting bracket 2 is assembled in place, the first guiding block 201 can be clamped, which can further prevent the mounting bracket 2 from shaking, so as to be beneficial to ensuring the positioning effect between the two. Correspondingly, as Figure 6 and Figure 7As shown in the figure, the mating surface 202 is provided at the bottom of the first guiding block 201 and is arranged in contact with the inclined surface that matches the guiding groove K as described above.

[0063] In addition, as a further embodiment, in combination with Figure 2 , Figure 5 and Figure 8 As shown in the figure, the positioning and guiding portion includes a second guiding unit that guides along the axial direction of the inner core 101. Among them, the second guiding unit includes a guiding inclined surface 1061 provided at the top of the inner core 101 and a mating inclined surface 203 that matches the guiding inclined surface 1061 and is provided at the bottom of the first guiding block 201. In this embodiment, by providing the second guiding unit that guides along the axial direction of the inner core 101, the suspension bracket 2 can be quickly positioned to the assembly position in the axial direction of the inner core 101, thereby further improving the connection efficiency between the suspension bracket 2 and the bushing 1.

[0064] And as a preferred embodiment, as Figure 2 and Figure 3 As shown in the figure, a second guiding block 106 protruding upward is provided at the top of the inner core 101, and the guiding inclined surface 1061 is provided on the second guiding block 106. By providing the second guiding block 106, it is convenient to arrange the guiding inclined surface 1061 on the second guiding block 106. Among them, as a specific embodiment, the angle between the guiding inclined surface 1061 of this embodiment and the end surface of the inner core 101 can be specifically set between 43° and 47°, and preferably set to 45°.

[0065] Based on the above overall description, when the suspension assembly of this embodiment is assembled, the guiding inclined surface 1061 of the bushing 1 is at the uppermost end of the inner core 101, and the mating inclined surface 203 of the suspension bracket 2 is at the lowermost end of the suspension bracket 2. When the suspension bracket 2 descends from top to bottom along the up-and-down direction of the vehicle body with the power assembly above the bushing 1, if the mating inclined surface 203 of the suspension bracket 2 and the guiding inclined surface 1061 of the inner core 101 partially coincide in the axial direction of the inner core 101, the suspension bracket 2 can be blocked and cannot continue to descend. At this time, the mating inclined surface 203 of the suspension bracket 2 slides along the guiding inclined surface 1061 of the bushing 1 until the end surface of the first guiding block 201 is flush with the end surface of the inner core 101 in its axial direction, so that the suspension bracket 2 can continue to descend with the power assembly.

[0066] Then, when the suspension bracket 2 continues to descend with the power assembly, the inclined surface of the first guiding block 201 can slide obliquely downward along the groove wall of the guiding groove K of the bushing 1, playing a role in guiding in the up-and-down direction of the vehicle body, and aligning the central hole 1011 of the inner core 101 with the mating hole 205 of the suspension bracket 2 in the up-and-down direction of the vehicle body.

[0067] Subsequently, the suspension bracket 2 continues to descend with the power assembly. When the assembly is in place, the two positioning surfaces 105 on the bump 104 will fit with the two mating surfaces 202 on the suspension bracket 2 and block the further descent of the suspension bracket 2. At this time, the central hole 1011 of the inner core 101 is aligned with the mating hole 205 of the suspension bracket 2 in the up-and-down direction of the whole vehicle, completing the positioning in this direction. Thus far, the end faces of the inner core 101 and the first guide block 201 are in contact, and the central hole 1011 and the mating hole 205 are aligned, allowing a bolt to pass through easily, thereby completing the assembly work.

[0068] Therefore, for the suspension assembly of this embodiment, by adopting the above structure, it is beneficial to accurately position the suspension bracket 2 and the bushing 1, which is beneficial to ensuring the connection efficiency between the two.

[0069] In addition, another object of this embodiment is to propose a vehicle, which is provided with the above suspension assembly.

[0070] The vehicle of this embodiment has all the beneficial effects of the above suspension assembly, which will not be elaborated here.

[0071] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
