Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a structural beam of a rear frame, a rear frame and a vehicle. Background Art

[0002] In the prior art, the structural beam in the rear frame for mounting the spare tire rack needs to be welded with at least two mounting brackets, which are then connected to the spare tire rack. This means that the number of structural components used to connect the spare tire rack is large, and many welding locations are required, which makes manufacturing more difficult and has a long production cycle. Secondly, as a structural component extending outward from the rear frame, the mounting bracket occupies a large amount of space at the bottom of the rear frame. Vehicle pipelines or other vehicle parts required to be installed on the rear frame need to avoid the mounting bracket, which makes installation and layout more difficult. Utility Model Content

[0003] In view of this, the present application provides a structural beam of a rear frame, a rear frame and a vehicle. This design occupies less space at the bottom of the rear frame, and the vehicle pipelines or other vehicle parts installed on the rear frame do not need to avoid the mounting bracket, so the installation and layout are less difficult.

[0004] In a first aspect, the present application provides a structural beam of a rear frame, wherein the structural beam is provided with a first mounting hole, the first mounting hole is used for mounting a bearing, and the bearing is used for being rotatably connected to the spare tire rack.

[0005] The first structural beam of the rear frame provided in the present application is connected to the spare tire rack via a bearing, i.e., the number of structural members used to connect the spare tire rack is relatively small, fewer welding locations are required, or even no welding is required, resulting in less manufacturing difficulty and a shorter production cycle. Furthermore, the bearing is located in the first mounting hole, resulting in a highly compact structure and less space occupied at the bottom of the rear frame. Vehicle pipelines or other vehicle parts required to be installed on the rear frame do not need to avoid the bearing, thus reducing the difficulty in installation and layout.

[0006] Optionally, the structural beam includes a recessed portion, the recessed portion includes a recessed bottom wall, and the first mounting hole extends from the recessed bottom wall into the structural beam.

[0007] Optionally, the recessed portion further includes a recessed side wall, the recessed side wall is connected to the recessed bottom wall, and at least a portion of the recessed side wall is arc-shaped.

[0008] Optionally, the structural beam includes a bending structure, the bending structure includes a first structural plate and a second structural plate connected to each other, and the extension direction of the first structural plate intersects with the extension direction of the second structural plate; wherein the first mounting hole is provided in the first structural plate or the second structural plate.

[0009] Optionally, if the first structural plate is provided with a first mounting hole, the bending structure also includes a third structural plate, the portion of the second structural plate facing away from the first structural plate is connected to the third structural plate, and the extension direction of the second structural plate intersects with the extension direction of the third structural plate; the third structural plate is also provided with a first mounting hole, and the first mounting hole located on the first structural plate and the first mounting hole located on the third structural plate are both through holes and are both used to install the same bearing.

[0010] Optionally, the extension direction of the structural beam is parallel to or perpendicular to the longitudinal direction of the rear frame.

[0011] In a second aspect, the present application provides a rear frame comprising a first structural beam, a second structural beam, and a third structural beam. The first structural beam is the structural beam of the rear frame described above, and therefore, the rear frame also includes the technical effects described above, which will not be repeated here. The second structural beam is connected to one end of the first structural beam, and the extension direction of the first structural beam intersects with the extension direction of the second structural beam; the third structural beam is connected to the other end of the first structural beam, and the extension direction of the first structural beam intersects with the extension direction of the third structural beam; the distance between the first mounting hole and the second structural beam is greater than the distance between the first mounting hole and the third structural beam.

[0012] Since the structural strength of the connection between the second structural beam and the first structural beam is relatively high, the structural strength of the portion where the first mounting hole is located in the first structural beam close to the second structural beam is also relatively high, and the structural strength of the connection structure between the first structural beam, the bearing and the spare tire rack is also relatively high, it is beneficial for the spare tire to be reliably and stably mounted on the rear frame.

[0013] If the distance between the first mounting hole and the second structural beam is greater than the distance between the first mounting hole and the third structural beam, this arrangement is also conducive to reliably and stably mounting the spare tire on the rear frame.

[0047] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0048] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0049] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0050] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0051] In the figures herein, direction X represents the longitudinal direction of the rear frame (the direction from the rear end of the vehicle to the front end of the vehicle), direction Y represents the lateral direction of the rear frame (the direction from the side of the vehicle to the other side of the vehicle), and direction Z represents the height direction of the rear frame (the direction from the bottom of the vehicle to the top of the vehicle). Directions X, Y, and Z are perpendicular to each other.

[0052] In a first aspect, an embodiment of the present application provides a structural beam of a rear frame. The structural beam is one of the components of the rear frame. The structural beam is used to provide the required structural strength for the rear frame. The structural beam can also serve as a mounting structure for other vehicle parts.

[0053] Please refer to Figure 1 As shown, this article first describes the first structural beam 1 of the rear frame as an example. The first structural beam 1 is provided with a first mounting hole 11 for mounting a bearing 20. The bearing 20 is rotatably connected to the spare tire carrier 30. The bearing 20 is fixed relative to the first structural beam 1, and the spare tire carrier 30 is used to mount a spare tire.

[0054] In the prior art, the structural beam in the rear frame for mounting the spare tire rack needs to be welded with at least two mounting brackets, which are then connected to the spare tire rack. This means that the number of structural components used to connect the spare tire rack is large, and many welding locations are required, which makes manufacturing more difficult and has a long production cycle. Secondly, as a structural component extending outward from the rear frame, the mounting bracket occupies a large amount of space at the bottom of the rear frame. Vehicle pipelines or other vehicle parts required to be installed on the rear frame need to avoid the mounting bracket, which makes installation and layout more difficult.

[0055] Compared to the prior art, the first structural beam 1 of the rear frame provided in the embodiment is connected to the spare tire carrier 30 via the bearing 20. That is, the number of structural components used to connect the spare tire carrier 30 is relatively small, fewer welding locations are required, or even no welding is required, resulting in less manufacturing difficulty and a shorter production cycle. Moreover, the bearing 20 is located in the first mounting hole 11, resulting in a more compact structure and occupying less space at the bottom of the rear frame. Vehicle pipelines or other vehicle parts required to be installed on the rear frame do not need to avoid the bearing 20, thereby reducing the difficulty in installation and layout.

[0056] Alternatively, see Figure 1 As shown, the first structural beam 1 includes a recessed portion 12, which includes a recessed bottom wall 121. The first mounting hole 11 extends from the recessed bottom wall 121 into the first structural beam 1. The provision of the recessed portion 12 provides the first structural beam 1 with at least two intersecting structural walls, resulting in a higher bending cross-sectional modulus for the first structural beam 1. This improves the structural strength of the first structural beam 1, the structural strength of the rear frame, and the smooth operation of the vehicle, providing a better driving experience for the user. Because the first mounting hole 11 for mounting the bearing 20 is located in the recessed bottom wall 121 of the recessed portion 12, the structural strength of the connection structure between the first structural beam 1, the bearing 20, and the spare tire holder 30 is also high, facilitating the reliable and stable mounting of the spare tire to the rear frame.

[0057] The recessed portion 12 further includes a recessed side wall 122 connected to the recessed bottom wall 121 , and an extension direction of the recessed side wall 122 intersects with an extension direction of the recessed bottom wall 121 .

[0058] In other embodiments (not shown in the figures), the first mounting hole 11 can extend from the recessed side wall 122 into the first structural beam 1. The technical effect of this embodiment is the same as the technical effect of the embodiment of "the first mounting hole 11 extends from the recessed bottom wall 121 into the first structural beam 1", and will not be repeated here.

[0059] Alternatively, see Figure 1 As shown, at least a portion of the recessed sidewall 122 is curved. This arrangement increases the bending section modulus of the first structural beam 1, further enhancing the structural strength of the first structural beam 1 and the rear frame, thereby further improving the smoothness of vehicle operation and providing a better driving experience for the user. The structural strength of the connection between the first structural beam 1, the bearing 20, and the spare tire holder 30 is also increased, further facilitating the reliable and stable installation of the spare tire on the rear frame.

[0060] Alternatively, see Figure 1 As shown, the first structural beam 1 is primarily formed by stamping metal sheets. Therefore, the first structural beam 1 includes a folded structure 13, which comprises a first structural plate 131 and a second structural plate 132 connected to each other. The first structural plate 131 extends in a direction that intersects with the second structural plate 132. The first mounting hole 11 is provided in the first structural plate 131. The first structural beam 1 with the folded structure 13 has a higher bending cross-sectional modulus, which helps improve the structural strength of the first structural beam 1 and the rear frame, thereby enhancing the smoothness of vehicle operation and providing a better driving experience for the user. Because the first mounting hole 11 for mounting the bearing 20 is located in the first structural plate 131 of the folded structure 13, the structural strength of the connection between the first structural beam 1, the bearing 20, and the spare tire holder 30 is also higher, facilitating the reliable and stable installation of the spare tire on the rear frame. Accordingly, the recessed portion 12 can also be located in the first structural plate 131.

[0061] In other embodiments (not shown in the figures), the first mounting hole 11 is arranged on the second structural plate 132. The technical effect of this embodiment is the same as the technical effect of the embodiment of "the first mounting hole 11 is arranged on the first structural plate 131", and will not be repeated here.

[0062] Alternatively, see Figure 2As shown, if the first structural plate 131 is provided with a first mounting hole 11, the bent structure 13 also includes a third structural plate 133. The portion of the second structural plate 132 facing away from the first structural plate 131 is connected to the third structural plate 133, and the extension direction of the second structural plate 132 intersects the extension direction of the third structural plate 133. The third structural plate 133 is also provided with a first mounting hole 11. The first mounting hole 11 in the first structural plate 131 and the first mounting hole 11 in the third structural plate 133 are both through-holes and are used to mount the same bearing 20. In this arrangement, for the first structural beam 1 formed from sheet metal, the thickness of the first structural plate 131 and the thickness of the third structural plate 133 are both relatively small, and the contact area of the inner wall surfaces of each first mounting hole 11 is also relatively small. The provision of "two first mounting holes 11 for mounting the same bearing 20" can increase the connection area between the first structural beam 1 and the bearing 20, thereby improving the reliability of the connection. Secondly, the forces at both ends of the bearing 20 distributed along the axis are relatively balanced, the bearing 20 is not prone to structural problems such as deformation, and the service life of the bearing 20 is relatively long.

[0063] The extension direction of the first structural plate 131 may be parallel to or intersect with the extension direction of the third structural plate 133 .

[0064] In addition, the cross-sectional shape of the first bending structure 13 can be a U-shape, a U-shape, or a C-shape.

[0065] In other embodiments (not shown in the figures), the first mounting hole may be a blind hole structure.

[0066] Optionally, the extending direction of the first structural beam 1 is parallel to the longitudinal direction of the rear frame, that is, the first structural beam 1 can be a longitudinal beam.

[0067] In other embodiments (not shown in the figures), the extending direction of the first structural beam 1 may be perpendicular to the longitudinal direction of the rear frame 10 , that is, the first structural beam 1 may be a cross beam.

[0068] Second, please refer to Figure 3 As shown, an embodiment of the present application provides a rear frame 10, which includes the first structural beam 1 described above. The rear frame 10 also includes the technical effects of the first structural beam 1 in the above content, which will not be repeated here. The rear frame 10 also includes a second structural beam 2 and a third structural beam 3. The second structural beam 2 is connected to one end of the first structural beam 1, and the extension direction (direction X) of the first structural beam 1 intersects with the extension direction (direction Y) of the second structural beam 2. The third structural beam 3 is connected to the other end of the first structural beam 1, and the extension direction (direction X) of the first structural beam 1 intersects with the extension direction (direction Y) of the third structural beam 3. The distance between the first mounting hole 11 and the second structural beam 2 is greater than the distance between the first mounting hole 11 and the third structural beam 3.

[0069] Since the structural strength of the connection between the second structural beam 2 and the first structural beam 1 is relatively high, the structural strength of the first mounting hole 11 located in the first structural beam 1 close to the second structural beam 2 is also relatively high, and the structural strength of the connection structure between the first structural beam 1, the bearing 20 and the spare tire holder 30 is also relatively high, which is conducive to reliably and stably mounting the spare tire on the rear frame 10.

[0070] If the first structural beam 1 is a longitudinal beam, the second structural beam 2 and the third structural beam 3 may both be transverse beams, and the extension direction of the second structural beam 2 and the extension direction of the third structural beam 3 are both perpendicular to the extension direction of the first structural beam 1 .

[0071] In other embodiments (not shown in the figures), the distance between the first mounting hole 11 and the second structural beam 2 is greater than the distance between the first mounting hole 11 and the third structural beam 3. This embodiment is also conducive to reliably and stably mounting the spare tire on the rear frame 10.

[0072] In a third aspect, an embodiment of the present application provides a vehicle comprising the rear frame 10 described above, a bearing 20, and a spare tire holder 30. The bearing 20 is mounted in the first mounting hole 11 of the first structural beam 1 of the rear frame 10. The bearing 20 is provided with a second mounting hole, and the spare tire holder 30 is mounted in the second mounting hole. The vehicle has the technical effects described above with respect to the rear frame 10, which will not be further elaborated here.

[0073] Optionally, the bearing 20 includes an outer curved wall, which is welded to the first mounting hole 11 to limit the movement of the bearing 20 relative to the first structural beam 1 .

[0074] In other embodiments (not shown in the figures), the bearing 20 may be snap-fitted to the first structural beam 1 , or the bearing 20 may be threadedly connected to the first structural beam 1 .

[0075] Optionally, the bearing 20 is a sliding bearing. Specifically, the bearing 20 can be an annular sleeve, also known as a bushing.

[0076] In other embodiments (not shown in the figures), the bearing 20 may be a rolling bearing.

[0077] Alternatively, see Figure 4-Figure 5As shown, the spare tire rack 30 includes a supporting rod 301, a limiting member 302 and a nut 303. The supporting rod 301 and the limiting member 302 are fixedly connected. The supporting rod 301 is passed through the first mounting hole 11. The limiting member 302 abuts against one side wall of the first structural beam 1. The nut 303 abuts against another opposite side wall of the first structural beam 1. The nut 303 is threadedly connected to the supporting rod 301. By rotating the nut 303, the nut 303 and the limiting member 302 can tighten and clamp the first structural beam 1 to limit the supporting rod 301 from being separated from the first mounting hole 11, so that the supporting rod 301 can stably support the spare tire.

[0078] Of course, the nut 303 can also be rotated to cancel the function of "the nut 303 and the limit member 302 fastening and clamping the first structural beam 1", so that the supporting rod 301 can rotate relative to the bearing 20, thereby making it easier for the user to remove the spare tire from the supporting rod 301.

[0079] The spare tire rack 30 further includes a hanging portion 304 , the other end structure of the supporting rod 301 is connected to the hanging portion 304 , the rear frame may include a fourth structural beam 4 , the fourth structural beam 4 includes a hook 41 , and the hanging portion 304 may be hung on the hook 41 .

[0080] In addition, the supporting rod 301 includes a first rod body 301a and a second rod body 301b connected to each other, and the extension direction of the first rod body 301a and the extension direction of the second rod body 301b intersect. Figure 4 The angle β shown or Figure 5 The angle α shown is used to adjust the rotation center of the spare tire carrier 30.

[0081] Furthermore, the spare tire rack 30 further includes a supporting plate 305 , which is connected to the first rod 301 a and is used to assist in supporting the spare tire.
