Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a rear suspension spring mount and a vehicle. Background Technology

[0002] In a vehicle, the rear suspension spring is connected to both the suspension and the rear longitudinal beam. During driving, the rear suspension spring absorbs vibrations from road bumps by changing its compression, thus improving vehicle comfort. Typically, one end of the rear suspension spring is fixedly connected to the vehicle's suspension, while the other end is fixedly connected to the rear longitudinal beam via a rear suspension spring mount.

[0003] The rear suspension spring mounting bracket is usually a plate-shaped structure with a circular protrusion in the middle. The other end of the rear suspension spring is sleeved on the outside of the circular protrusion and abuts against the candidate spring mounting bracket. The rear suspension spring mounting bracket is welded to the top plate of the rear longitudinal beam. In this way, the rear suspension spring can be compressed and fixed between the suspension and the rear suspension spring mounting bracket, thereby achieving a fixed connection of the rear suspension spring.

[0004] However, since different vehicle models may have different compression requirements for the rear suspension springs, the only way to change the compression is to redesign the rear longitudinal beam and adjust the height of the side plates of the rear longitudinal beam to change the installation position of the rear suspension springs in terms of height. However, this method increases the development cost of the vehicle and reduces the development efficiency. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0042] This application provides a rear suspension spring mounting bracket, such as... Figure 1 and Figure 2 As shown, the rear suspension spring mounting bracket 1 includes a connecting plate 11 and a mounting platform 12. The mounting platform 12 is welded to the connecting plate 11, and the connecting plate 11 is used to weld to the rear longitudinal beam 2, thereby fixing the mounting platform 12 and the rear longitudinal beam 2 together. The mounting platform 12 is used to position the rear suspension spring.

[0043] The rear longitudinal beam 2 includes two rear longitudinal beam side plates 21 and a rear longitudinal beam intermediate plate 22. The two opposite ends of the rear longitudinal beam intermediate plate 22 are respectively connected to one of the rear longitudinal beam side plates 21, so that the cross-section of the rear longitudinal beam 2 is U-shaped. When welding the connecting plate 11 to the rear longitudinal beam 2, the connecting plate 11 can be welded to the rear longitudinal beam side plates 21 of the rear longitudinal beam 2.

[0044] In one possible implementation, the structure of the connecting plate 11 can be as follows: the connecting plate 11 includes a middle plate 111 and two connecting side plates 112. The middle plate 111 has a rectangular structure. The first end and the second end of the middle plate 111 are respectively connected to the first end of a connecting side plate 112. The first end and the second end of the middle plate 111 are opposite to each other. The included angle between the connecting side plate 112 and the middle plate 111 is less than 180°. In this way, the cross-section of the connecting plate 11 can also be U-shaped.

[0045] The intermediate plate 111 can be welded to the mounting platform 12, thereby fixing the mounting platform 12 and the connecting plate 11 together. The two connecting side plates can be welded to one of the rear longitudinal beam side plates 21 of the rear longitudinal beam 2 respectively, thereby fixing the connecting plate 11 and the mounting platform 12 to the rear longitudinal beam 2.

[0046] When the mounting platform 12 is welded to the intermediate plate 111, the mounting platform 12 can be installed on the side of the intermediate plate 111 away from the connecting side plate 112. That is, after the mounting platform 12 is welded to the intermediate plate 111, the mounting platform 12 and the connecting side plate 112 are located on both sides of the intermediate plate 111. In this way, the connecting side plate 112 will not hinder the installation between the mounting platform 12 and the rear suspension spring, nor will the mounting platform 12 hinder the welding connection between the connecting side plate 112 and the rear longitudinal beam side plate 21.

[0047] In one possible implementation, the mounting platform 12 may also have a tool clamping hole 122. When welding the mounting platform 12 to the intermediate plate 111, a clamping tool (e.g., pliers) is needed to hold the mounting platform 12 to fix its position relative to the intermediate plate 111 before welding. Therefore, a tool clamping hole 122 is provided on the mounting platform 12. The tool clamping hole 122 can be located near the edge of the mounting platform 12. This way, when using a clamping tool to hold the mounting platform 12, one leg of the clamping tool can extend into the tool clamping hole 122, and the other leg can be placed on the outside of the edge of the mounting platform 12. Then, the operator can control the two legs of the clamping tool to clamp and hold the mounting platform 12.

[0048] The structure and method for positioning the rear suspension spring using the mounting platform 12 are as follows: The mounting platform 12 has a first protrusion 121, the protrusion direction of which is away from the connecting side plate 112. The first protrusion 121 is used to position the rear suspension spring. When positioning the rear suspension spring, the rear suspension spring can be looped around the outer ring of the first protrusion 121, thereby positioning one end of the rear suspension spring. Since the other end of the rear suspension spring is used to connect to the vehicle body, the mounting platform 12 and the vehicle body clamp the rear suspension spring between them, and the mounting platform 12 and the vehicle body respectively position both ends of the rear suspension spring.

[0049] In one possible implementation, the shape of the first protrusion 121 can be any reasonable shape. For example, the first protrusion 121 can be a circular protrusion, or of course, a square protrusion, etc. The embodiments of this application do not limit this.

[0050] In one possible implementation, the mounting platform 12 may also have a first process hole 123 for applying electrophoretic coating and draining liquid during the welding connection between the mounting platform 12 and the intermediate plate 111. The electrophoretic liquid can enter between the mounting platform 12 and the intermediate plate 111 through the first process hole 123, and excess liquid can flow out through the first process hole 123. The first process hole 123 can be located at any reasonable position on the mounting platform 12. For example, the first process hole 123 can be located at the top of the first protrusion 121, or other positions as described in this embodiment.

[0051] In one possible implementation, to enhance the strength of the mounting platform 12, a second flange 124 may be provided at the edge of the mounting platform 12, the second flange 124 being located on the same side of the mounting platform 12 as the first protrusion 121.

[0052] The welding connection between the connecting side plate 112 and the rear longitudinal beam side plate 21 can be achieved by welding the inner walls of the two connecting side plates 112 to the outer wall of one of the rear longitudinal beam side plates 21. In this way, when the compression of the rear suspension spring changes, the distance between the intermediate plate 111 and the intermediate plate 22 of the rear longitudinal beam can be adjusted by changing the height of the connecting side plate 112 connected to the rear longitudinal beam side plate 21. Since the mounting platform 12 is welded to the intermediate plate 111, the distance between the mounting platform 12 and the intermediate plate 22 of the rear longitudinal beam can also be adjusted. Thus, without changing the structure and position of the rear longitudinal beam 2 in the vehicle, the position of the rear suspension spring mounting seat 1 in the vehicle can be changed, thereby adjusting the compression of the rear suspension spring.

[0053] In one possible implementation, to enhance the strength of the connecting side plate 112, the connecting side plate 112 may be configured as follows: the connecting side plate 112 has a first strip-shaped protrusion 1121.

[0054] The first strip-shaped protrusion 1121 extends transversely through the side plate 112 in one direction. For example, the end of the side plate 112 that is connected to the middle plate 111 is the first end of the side plate 112, and the end opposite to the first end is the second end of the side plate 112. The first strip-shaped protrusion 1121 can extend transversely through the side plate 112 in the direction of the first end and the second end of the side plate 112.

[0055] The first strip-shaped protrusion 1121 protrudes in a direction away from the intermediate plate 111, that is, protruding towards the outer side of the connecting side plate 112. In this way, it can avoid hindering the welding connection between the connecting side plate 112 and the rear longitudinal beam side plate 21 when the inner side of the connecting side plate 112 is welded to the outer side of the rear longitudinal beam side plate 21.

[0056] In one possible implementation, to enhance the stability of the connection between the rear suspension spring mount 1 and the rear longitudinal beam 2, the following configuration can also be made:

[0057] like Figure 1 and Figure 2 As shown, the spring mounting base 1 also includes two first reinforcing plates 13.

[0058] The third and fourth ends of the intermediate plate 111 each have a first flange 1111. The first flange 1111 and the connecting side plate 112 are located on both sides of the intermediate plate 111. For example, when the intermediate plate 111 is placed horizontally, if the connecting side plate 112 extends to the lower side of the intermediate plate 111, the first flange 1111 extends to the upper side of the intermediate plate 111, so that the connecting side plate 112 and the first flange 1111 are located on both sides of the intermediate plate 111. In this way, the first flange 1111 will not obstruct the intermediate plate 22 of the rear longitudinal beam when the connecting side plate 112 is welded to the rear longitudinal beam side plate 21.

[0059] Each first reinforcing plate 13 can be welded to a first flange 1111 and the middle plate 22 of the rear longitudinal beam 2, respectively. In this way, the connection between the rear suspension spring mounting seat 1 and the rear longitudinal beam 2 includes the welding connection between the connecting side plate 112 and the rear longitudinal beam side plate 21, and the welding connection between the first reinforcing plate 13 and the middle plate 22 of the rear longitudinal beam, thereby enhancing the stability of the connection between the rear suspension spring mounting seat 1 and the rear longitudinal beam 2.

[0060] In one possible implementation, the structure of the first reinforcing plate 13 can be varied. The following is an example of one of them: The first reinforcing plate 13 can have a horizontal plate 131 and a vertical plate 132. One end of the horizontal plate 131 is connected to one end of the vertical plate 132, so that the cross section of the first reinforcing plate 13 is L-shaped.

[0061] When fixing the first reinforcing plate 13, the horizontal plate 131 is used to weld and connect with the middle plate 22 of the rear longitudinal beam 2, and the vertical plate 132 is used to weld and connect with the first flange 1111.

[0062] When the horizontal plate 131 is welded to the middle plate 22 of the rear longitudinal beam, the side of the horizontal plate 131 away from the vertical plate 132 can be welded to the side of the middle plate 22 of the rear longitudinal beam away from the side plate 21 of the rear longitudinal beam.

[0063] When the vertical plate 132 is welded to the first flange 1111, the side of the vertical plate 132 away from the horizontal plate 131 can be welded to the side of the first flange 1111 away from the middle plate 111.

[0064] In one possible implementation, to enhance the strength of the first reinforcing plate 13, the first reinforcing plate 13 may be configured to have a second strip-shaped protrusion 133.

[0065] The second strip-shaped protrusion 133 extends across the first reinforcing plate 13 in one direction. For example, the second strip-shaped protrusion 133 may be located on the horizontal plate 131 and the vertical plate 132, extending across the horizontal plate 131 and the vertical plate 132.

[0066] The first strip-shaped protrusion 133 has the following protrusion direction: the portion of the first strip-shaped protrusion 133 located on the horizontal plate 131 protrudes away from the rear longitudinal beam intermediate plate 22. This avoids obstructing the welding connection between the horizontal plate 131 and the rear longitudinal beam intermediate plate 22 during welding. The portion of the first strip-shaped protrusion 133 located on the vertical plate 132 protrudes away from the first flange 1111. This avoids obstructing the welding connection between the vertical plate 132 and the first flange 1111 during welding.

[0067] In one possible implementation, to enhance the stability of the rear suspension spring mount 1, the following settings can also be made:

[0068] like Figure 2 As shown, the rear suspension spring mounting bracket 1 also includes a second reinforcing plate 14.

[0069] The second reinforcing plate 14 is used to weld and connect to the connecting side plate 112 and the mounting platform 12 respectively, thereby enhancing the stability of the connection between the connecting plate 11 and the mounting platform 12.

[0070] When welding the mounting platform 12 to the intermediate plate 111, the position of the mounting platform 12 can be adjusted between the first end and the second end of the intermediate plate 111 according to the requirements of the rear suspension spring. That is, the mounting platform 12 can be fixed at a position closer to the first end of the intermediate plate 111, or at a position closer to the second end of the intermediate plate 111, or at the center of the intermediate plate 111, as required.

[0071] When the mounting platform 12 is fixed at a position closer to the first end of the intermediate plate 111, the mounting platform 12 may protrude from the first end of the intermediate plate 111. At this time, the second reinforcing plate 14 can be welded to the connecting side plate 112 of the mounting platform 12 at the end protruding from the intermediate plate 111 and the end closer to the first end of the intermediate plate 111, thereby providing a fixed support for the mounting platform 12 and making it more stable.

[0072] When the mounting platform 12 is fixed at the second end closer to the middle plate 111, the mounting platform 12 may protrude from the second end of the middle plate 111. At this time, the second reinforcing plate 14 can be welded to the connecting side plate 112 of the mounting platform 12 at the end protruding from the middle plate 111 and the second end closer to the middle plate 111, thereby providing a fixed support for the mounting platform 12.

[0073] If the mounting platform 12 is relatively long, when the mounting platform 12 is fixed at the middle position of the intermediate plate 111, and the two ends of the mounting platform 12 protrude from the first end and the second end of the intermediate plate 111 respectively, two second reinforcing plates 14 can be provided. One of the second reinforcing plates 14 is welded to the connecting side plate 112 of the end of the mounting platform 12 that protrudes from the intermediate plate 111 and the end near the first end of the intermediate plate 111, respectively. The other second reinforcing plate is welded to the connecting side plate 112 of the end of the mounting platform 12 that protrudes from the intermediate plate 111 and the end near the second end of the intermediate plate 111, thereby providing fixed support for both ends of the mounting platform 12 that protrude from the intermediate plate 111.

[0074] Of course, when the mounting platform 12 is fixed at the first end closer to the middle plate 111, or when the mounting platform 12 is fixed at the second end closer to the middle plate 111, with the two ends of the mounting platform 12 protruding from the first end and the second end of the middle plate 111 respectively, two second reinforcing plates can be provided to fix and support the two ends of the mounting platform 12 respectively, as described above.

[0075] In one possible implementation, the structure of the second reinforcing plate 14 can also be a variety of reasonable structures. For example, it can be an L-shaped structure like the first reinforcing plate 13, or it can be other plate structures with curvature. This application embodiment does not limit this.

[0076] The second reinforcing plate 14 will now be described in more detail, taking one possible structure as an example:

[0077] like Figure 3 , Figure 4 and Figure 5 As shown, the second reinforcing plate 14 includes a first welding plate 142, a second welding plate 143, and a support plate 144. The first welding plate 142 and the second welding plate 143 are fixedly connected to the support plate 144. The included angle between the first welding plate 142 and the support plate 144 can be greater than 90° and less than 180°, and the angle between the second welding plate 143 and the support plate 144 can be greater than 90° and less than 180°.

[0078] When it is necessary to fix the second reinforcing plate 14, the first welding plate 142 is used to weld and connect with the mounting platform 12, so that the second reinforcing plate 14 is fixedly connected with the mounting platform 12. The second welding plate 143 is used to weld and connect with the connecting side plate 112, so that the second reinforcing plate 14 is fixedly connected with the connecting side plate 112, thereby playing a fixed support role for the mounting platform 12.

[0079] When the first welding plate 142 is welded to the mounting platform 12, the side of the first welding plate 142 away from the second welding plate 143 can be welded to the side of the mounting platform 12 near the middle plate 111.

[0080] When the second welding plate 143 is welded to the connecting side plate 112, the side of the second welding plate 143 away from the first welding plate 142 can be welded to the outside of the connecting side plate 112 (i.e. the side away from the intermediate plate 111).

[0081] In one possible implementation, the second reinforcing plate 14 further has a second process hole 141 for applying electrophoresis and discharging liquid during the welding connection of the second reinforcing plate 14 to the connecting side plate 112. The electrophoretic liquid can flow through the second process hole 141 between the second reinforcing plate 14 and the connecting side plate 112, or between the second reinforcing plate 14 and the mounting platform 12. Excess liquid can also flow out through the second process hole 141. The second process hole 141 can be located at any reasonable position on the second reinforcing plate 14. For example, the second process hole 141 can be located on the support plate 144. Of course, it can also be in other positions, which are not limited in this embodiment.

[0082] In one possible implementation, to enhance the strength of the second reinforcing plate 14, the second reinforcing plate 14 may be configured as follows: the second reinforcing plate 14 includes an edge protrusion 145, the protrusion direction of the edge protrusion 145 being away from the mounting platform 12 or away from the connecting side plate 112.

[0083] The edge protrusion 145 can be located at the edge of the second reinforcing plate 14.

[0084] When the tool clamping hole 122 is located near the second reinforcing plate 14 on the mounting platform 12, the edge protrusion 145 can be located at the edge of the first welding plate 142. After the first welding plate 142 is welded to the mounting platform 12, the position of the edge protrusion 145 can correspond to the position of the tool clamping hole 122. Figure 3 As shown, there is a gap between the edge protrusion 145 and the mounting platform 12, which avoids the first welding plate 142 from blocking the tool clamping hole 122 after the first welding plate 142 is welded to the mounting platform 12.

[0085] The edge protrusion 145 can also be located at the edge of the second welding plate 143. In this way, when the second reinforcing plate 14 is welded together, there is a gap between the edge protrusion 145 and the connecting side plate 112, which can be used for leakage or gas discharge during welding.

[0086] This application also provides a vehicle comprising any of the aforementioned rear suspension spring mounting brackets 1 and rear longitudinal beams 2. The rear longitudinal beam 2 includes two rear longitudinal beam side plates 21 and a rear longitudinal beam intermediate plate 22, with each of the opposite ends of the intermediate plate 22 connected to one of the rear longitudinal beam side plates 21. The two connecting side plates 112 of the rear suspension spring mounting bracket 1 are respectively welded to one of the rear longitudinal beam side plates 21.

[0087] The technical solutions provided by the embodiments of this application have at least the following beneficial effects:

[0088] This application provides a rear suspension spring mounting bracket 1, which includes a connecting plate 11 and a mounting platform 12. The connecting plate 11 includes a middle plate 111 and two connecting side plates 112. The middle plate 111 has a rectangular structure. The first end and the second end of the middle plate 111 are respectively connected to the first end of one of the connecting side plates 112. The first end of the middle plate 111 and the second end of the middle plate 111 are opposite each other, and the included angle between the connecting side plates 112 and the middle plate 111 is less than 180°. The mounting platform 12 is welded to the middle plate 111, and the mounting platform 12 and the connecting side plates 112 are respectively located on both sides of the middle plate 111. The mounting platform 12 has a first protrusion 121, the protrusion direction of which is away from the connecting side plates 112. The first protrusion 121 is used to position the rear suspension spring. The two connecting side plates 112 are respectively used to be welded to one of the rear longitudinal beam side plates 21 of the rear longitudinal beam 2. By adopting this application, when different compression requirements are needed for the rear suspension spring, it is only necessary to adjust the relative height between the connecting side plate 112 and the rear longitudinal beam side plate 21 when welding the two connecting side plates 112 of the rear suspension spring mounting seat 1 to the two rear longitudinal beam side plates 21 of the rear longitudinal beam 2, so as to achieve different compression requirements for the rear suspension spring. In this way, there is no need to redevelop the rear longitudinal beam 2, saving development costs and improving development efficiency.

[0089] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
