[0027] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0028] Reference below Figure 1-Figure 4 The bent tube beam 100 according to the embodiment of the utility model can reduce the unsprung mass of the rear suspension, reduce the impact of the rear suspension on the vehicle body, and also reduce the bending degree of the bent tube beam 100, thereby improving the comfort and durability of the vehicle.

[0029] Combination Figure 1-Figure 4As shown, the bent tube beam 100 of the vehicle according to the first embodiment of the utility model mainly comprises a first beam body 1, a second beam body 2 and a mounting bracket 3. The bent tube beam 100 is the main force-bearing structure on the rear suspension.

[0030] Specifically, the first beam body 1 includes a first curved beam section 11 bent backward, the second beam body 2 is arranged opposite to the first beam body 1 in the lateral direction of the vehicle, the second beam body 2 includes a second curved beam section 21 bent backward, and the mounting bracket 3 is respectively connected to one end of the first curved beam section 11 and one end of the second curved beam section 21, and the first curved beam section 11, the second curved beam section 21 and the mounting bracket 3 form a motor avoidance groove 31.

[0031] Among them, in the lateral direction (that is, the left and right direction), the first beam body 1 and the second beam body 2 are arranged corresponding to each other, one end of the first beam body 1 and the second beam body 2 is connected to the frame, and the first beam body 1 and the second beam body 2 respectively have a first curved beam section 11 and a second curved beam section 21 bent backward, and the mounting bracket 3 is connected between the first curved beam section 11 and the second curved beam section 21, so that the first beam body 1 and the second beam body 2 can be connected as a whole. Compared with the integrated bent tube beam (the unsprung mass of the integrated bent tube beam is large, and the bent tube beam is easy to deform during movement; the middle part of the integrated bent tube beam has a large bending angle to avoid the rear motor, and the lateral stiffness is low during movement), the split-connected bent tube beam 100 can, on the one hand, effectively reduce the unsprung mass of the rear suspension, thereby reducing the impact of the rear suspension on the vehicle body, thereby improving the comfort of the vehicle, and on the other hand, it can also improve the lateral stiffness of the first beam body 1 and the second beam body 2 on the basis of the bent tube beam 100 avoiding the rear motor, thereby improving the durability of the bent tube beam 100.

[0032] In addition, the first curved beam section 11, the second curved beam section 21 and the mounting bracket 3 form a motor avoidance groove 31, which can be used to avoid the rear motor of the vehicle and prevent collision and interference between the curved tube beam 100 and the rear motor, thereby improving the rationality of the layout of the curved tube beam 100.

[0033] Therefore, by providing the bent tube beam 100, it is possible to reduce the unsprung mass of the rear suspension, reduce the impact of the rear suspension on the vehicle body, thereby improving the comfort of the vehicle, and also reduce the bending degree of the bent tube beam 100, thereby improving its durability.

[0034] Optionally, combined Figure 1 and Figure 2 As shown, the first beam body 1 also includes a first straight beam section 12, which is connected to the other end of the first curved beam section 11, and the angle between the line connecting the centers of the two ends of the first curved beam section 11 and the central axis of the first straight beam section 12 is α1, and α1 satisfies the relationship: α1≤22°. One end of the first straight beam section 12 can be connected to the wheel end through a flange.

[0035] That is to say, the two ends of the first straight beam section 12 can be connected to the first curved beam section 11 and the wheel end respectively, and the first straight beam section 12 is linear in structure, which is conducive to matching and installing with the wheel end. In addition, compared with the traditional one-piece curved tube beam, the angle α1 between the line connecting the centers of the two ends of the first curved beam section 11 and the central axis of the first straight beam section 12 is smaller, so that the bending angle of the curved tube beam 100 can be reduced, thereby improving the lateral stiffness of the curved tube beam 100 during the movement of the vehicle, and then improving the durability of the curved tube beam 100. For example, α1 can be 15°, 18°, 20° and 22°, but is not limited thereto.

[0036] Alternatively, combining Figure 1 and Figure 2 As shown, the second beam body 2 further includes a second straight beam section 22, which is connected to the other end of the second curved beam section 21, and the angle between the line connecting the centers of the two ends of the second curved beam section 21 and the central axis of the second straight beam section 22 is α2, and α2 satisfies the relationship: α2≤22°. One end of the second straight beam section 22 can be connected to the wheel end through a flange.

[0037] That is to say, the two ends of the second straight beam section 22 can be connected to the second curved beam section 21 and the wheel end respectively, and the second straight beam section 22 is linear in structure, which is conducive to matching and installing with the wheel end. In addition, compared with the traditional one-piece curved tube beam, the angle α2 between the connecting line of the two ends of the second curved beam section 21 and the central axis of the second straight beam section 22 is smaller, so that the bending angle of the curved tube beam 100 can be reduced, thereby improving the lateral stiffness of the curved tube beam 100 during the movement of the vehicle, and then improving the durability of the curved tube beam 100. For example, α2 can be 15°, 18°, 20° and 22°, but is not limited thereto.

[0038] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 2 As shown, a first bushing 111 is provided at one end of the first curved beam section 11 , and the first bushing 111 is connected to the mounting bracket 3 ; and / or a second bushing 211 is provided at one end of the second curved beam section 21 , and the second bushing 211 is connected to the mounting bracket 3 .

[0039] Specifically, the bushing has the function of reducing friction between mechanical parts and improving the wear resistance of mechanical parts, so the use of the form in which one end of the first curved beam section 11 is connected to the mounting bracket 3 through the first bushing 111 can effectively extend the service life of the first curved beam section 11 and the mounting bracket 3. The effect of connecting one end of the second curved beam section 21 to the mounting bracket 3 through the second bushing 211 is the same as above.

[0040] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 2As shown, at least a portion of the first curved beam section 11 is bent into an arc shape; and / or at least a portion of the second curved beam section 21 is bent into an arc shape.

[0041] Furthermore, at least a portion of the first curved beam section 11 is bent into an arc shape, so that the first curved beam section 11 can change its original structural extension direction, thereby meeting the need to avoid the motor and further improving its design rationality.

[0042] Furthermore, at least a portion of the second curved beam section 21 is also bent into an arc shape, so that the second curved beam section 21 can change its original structural extension direction, thereby cooperating with the first curved beam section 11 to meet the need of avoiding the motor, thereby improving its design rationality.

[0043] According to some optional embodiments of the present invention, combined with Figure 1-Figure 3 As shown, the mounting bracket 3 is formed with a mounting cavity 32 , the lower end of the mounting cavity 32 is open, and one end of the first curved beam section 11 and one end of the second curved beam section 21 extend into the mounting cavity 32 from the opening.

[0044] Among them, in the up and down directions, the upper end of the mounting bracket 3 is connected and fixed on the frame, and the mounting bracket 3 forms a mounting cavity 32 which opens downward, and the first curved tube beam 100 and the second curved tube beam 100 extend upward into the mounting cavity 32 at one end close to the mounting bracket 3. Compared with the integrated curved tube beam, the first curved tube beam 100 and the second curved tube beam 100 can be connected to the mounting bracket 3 to establish an indirect connection relationship with the frame. This connection method can transfer part of the weight on the first curved tube beam 100 and the second curved tube beam 100 to the frame, thereby achieving the effect of reducing the unsprung mass and reducing the impact of the rear suspension on the vehicle body, thereby improving the vehicle comfort.

[0045] Specifically, combined Figure 1 , Figure 3 and Figure 4 As shown, the mounting bracket 3 includes a first mounting plate 33, a second mounting plate 34, a first connecting plate 35 and a second connecting plate 36. The first mounting plate 33 and the second mounting plate 34 are arranged opposite to each other in the longitudinal direction of the vehicle. The first connecting plate 35 is connected to one side of the first mounting plate 33 and one side of the second mounting plate 34, and the second connecting plate 36 is connected to the other side of the first mounting plate 33 and the other side of the second mounting plate 34. The first mounting plate 33, the second mounting plate 34, the first connecting plate 35 and the second connecting plate 36 together form a mounting cavity 32, and one end of the first curved beam section 11 and one end of the second curved beam section 21 are respectively connected to the first mounting plate 33 and the second mounting plate 34.

[0046] It can be understood that in the longitudinal direction (that is, the front-to-back direction), the first mounting plate 33 and the second mounting plate 34 are arranged corresponding to each other; in the transverse direction (that is, the left-to-right direction), the first connecting plate 35 and the second connecting plate 36 are arranged corresponding to each other, and the first connecting plate 35 and the second connecting plate 36 are respectively connected to the two sides of the first mounting plate 33 and the second mounting plate 34, and the first mounting plate 33, the first connecting plate 35, the second mounting plate 34 and the second connecting plate 36 are connected in sequence to jointly define the mounting cavity 32, so that the overall frame of the mounting bracket 3 can be formed, and the first mounting plate 33, the second mounting plate 34, the first connecting plate 35 and the second connecting plate 36 correspond to each other, which can simplify the manufacturing process of the mounting bracket 3 and reduce the processing difficulty of the mounting bracket 3.

[0047] In addition, both sides of one end of the first curved beam section 11 and the second curved beam section 21 in the longitudinal direction are respectively connected to the first mounting plate 33 and the second mounting plate 34, so that the first curved beam section 11 and the second curved beam section 21 can establish a stable connection relationship with the mounting bracket 3.

[0048] Furthermore, combined with Figure 1 , Figure 3 and Figure 4 As shown, the distance between the first connecting plate 35 and the second connecting plate 36 decreases in the direction from top to bottom. That is, the upper ends of the first connecting plate 35 and the second connecting plate 36 are connected to the vehicle frame, and the lower ends of the first connecting plate 35 and the second connecting plate 36 are structures that define the mounting cavity 32, so the distance between the first connecting plate 35 and the second connecting plate 36 gradually decreases in the direction from top to bottom, so that on the one hand, the upper ends of the first connecting plate 35 and the second connecting plate 36 can be connected to the vehicle frame with a larger contact area, and on the other hand, the lower ends of the first connecting plate 35 and the second connecting plate 36 and the lower ends of the first mounting plate 33 and the second mounting plate 34 can jointly define a smaller envelope space of the first curved beam section 11 and the second curved beam section 21 close to one end of the mounting bracket 3, thereby improving the rationality of its arrangement.

[0049] Specifically, combined Figure 4 As shown, first bevel edges 331 sloping downward in a direction extending from the end to the middle are formed on both sides of the bottom of the first mounting plate 33; and / or second bevel edges 341 sloping downward in a direction extending from the end to the middle are formed on both sides of the bottom of the second mounting plate 34.

[0050] It can be understood that the first mounting plate 33 and the second mounting plate 34 have a first bevel 331 and a second bevel 341 respectively formed on both sides of the bottom thereof, which are inclined downward in a direction extending from the end portion to the middle. In this way, the lower ends of the first mounting plate 33 and the second mounting plate 34 and the lower ends of the first connecting plate 35 and the second connecting plate 36 can jointly define a smaller envelope space of the first bent beam section 11 and the second bent beam section 21 close to one end of the mounting bracket 3, and can also reduce the manufacturing materials of the first mounting plate 33 and the second mounting plate 34, thereby improving the rationality of the design.

[0051] The vehicle according to the embodiment of the second aspect of the utility model comprises the bent tube beam 100 of the vehicle of the above embodiment, so that the vehicle having the bent tube beam 100 can improve its own comfort and service life.

[0052] According to some optional embodiments of the present invention, the vehicle includes a control arm 200 , and the control arm 200 is respectively mounted on the corresponding first beam body 1 and the second beam body 2 through a control arm bracket 300 .

[0053] For example, combined with Figure 4 As shown, the first beam body 1 and the second beam body 2 each correspond to a control arm 200, and the control arm 200 is a lower control arm 202, that is, the first beam body 1 and the second beam body 2 are respectively connected (such as welded) with a lower control arm 202, so that a larger space can be provided for arranging the rear electric axle, and a larger electric axle can be arranged, thereby improving the vehicle's dynamics and improving off-road capabilities.

[0054] For example, combined Figure 1 As shown, the first beam body 1 and the second beam body 2 each correspond to two control arms 200, and the two control arms 200 are an upper control arm 201 and a lower control arm 202. That is to say, the first beam body 1 and the second beam body 2 each correspond to an upper control arm 201 and a lower control arm 202, one end of the upper control arm 201 is connected to the frame longitudinal beam, and the other end of the upper control arm 201 is connected to the corresponding first beam body 1 or the second beam body 2; one end of the lower control arm 202 is connected to the frame longitudinal beam, and the other end of the lower control arm 202 is connected to the corresponding first beam body 1 or the second beam body 2, so that the comfort of the vehicle can be improved.
