[0046] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 6 The anti-collision beam 100 according to the first embodiment of the present invention is described. In the following description of the present application, the anti-collision beam 100 is used for the subframe 200 of the vehicle 300 as an example.

[0047] like Figure 1 As shown, the anti-collision beam 100 according to the first embodiment of the utility model comprises an anti-collision section 1 and a plurality of connecting sections 2. In the description of the utility model, the meaning of "plurality" is two or more.

[0048] Specifically, the outer contour of the anti-collision segment 1 includes the width direction of the anti-collision segment 1 (such as Figure 1 The first side edge 11 and the second side edge 12 are opposite to each other in the vertical direction (as shown in the figure), and the plurality of connecting sections 2 are respectively connected to the anti-collision section 1 in the length direction (as shown in the figure) of the anti-collision section 1. Figure 1 The two ends of the connecting section 2 are connected in the left-right direction as shown, and one side edge of the connecting section 2 in the width direction protrudes from the first side edge 11 or the second side edge 12 of the anti-collision section 1 on the same side.

[0049] For example, in Figure 1-Figure 3 In the example, the first side edge 11 and the second side edge 12 are respectively located on both sides of the anti-collision section 1 in the up-down direction, and two connecting sections 2 are provided, and the two connecting sections 2 are respectively connected to the left and right ends of the anti-collision section 1. In other words, the left and right ends of the anti-collision section 1 are respectively connected to a connecting section 2. Of course, only the left end of the anti-collision section 1 is connected to multiple connecting sections 2, and the multiple connecting sections 2 are connected along the thickness direction of the anti-collision section 1 (such as Figure 1 Only the right end of the anti-collision segment 1 is connected to a plurality of connecting segments 2, and the plurality of connecting segments 2 are arranged in sequence along the thickness direction of the anti-collision segment 1; the left and right ends of the anti-collision segment 1 are respectively connected to a plurality of connecting segments 2, and the plurality of connecting segments 2 are arranged in sequence along the thickness direction of the anti-collision segment 1.

[0050] The arrangement of the connecting section 2, the first side edge 11 and the second side edge 12 includes the following situations: First, the upper side edge of the second connecting section 2 protrudes from the first side edge 11 of the anti-collision section 1 (such as Figure 1 and Figure 2 Second, the upper side edge of the connecting section 2 protrudes from the second side edge 12 of the anti-collision section 1 (not shown). Third, the lower side edge of the connecting section 2 protrudes from the first side edge 11 of the anti-collision section 1 (as shown). Figure 3 Fourth, the lower side edge of the connecting section 2 protrudes from the second side edge 12 of the anti-collision section 1 (not shown in the figure).

[0051] In this way, the structure of the anti-collision section 1 and the connecting section 2 is simple and easy to produce, thereby improving the production efficiency of the anti-collision beam 100. In addition, the anti-collision beam 100 can also reduce the collision and improve the performance of safe collision. In addition, when the anti-collision beam 100 is used for the subframe 200 of the vehicle 300, when the upper side edge of the connecting section 2 protrudes from the first side edge 11 of the anti-collision section 1, the distance between the second side edge 12 and the road surface is large (such as Figure 2 As shown, the first case above), or the upper side edge of the connecting section 2 protrudes from the second side edge 12 of the anti-collision section 1, and the distance between the first side edge 11 and the road surface is large (not shown, the second case above), the anti-collision beam 100 is a lower arch structure, which meets the requirements of multi-purpose vehicles (MPV) for small approach angles, safe collisions and heat dissipation, and the anti-collision beam 100 is suitable for MPV models (multi-purpose vehicles). When the lower side edge of the connecting section 2 protrudes from the first side edge 11 of the anti-collision section 1, the distance between the first side edge 11 and the road surface is large (as shown). Figure 3As shown, the third case mentioned above), or the lower side edge of the connecting section 2 protrudes from the second side edge 12 of the anti-collision section 1, and the distance between the second side edge 12 and the road surface is relatively large (not shown in the figure, the fourth case mentioned above), the anti-collision beam 100 is an upper bow-shaped structure, which meets the requirements of sport utility vehicles (SUV) for large approach angles and safe collisions. The anti-collision beam 100 is suitable for SUV models (sports utility vehicles), and the anti-collision beam 100 can be installed on vehicles 300 of different models, which improves the commonality of the installation of the anti-collision beam 100, thereby improving the performance of the anti-collision beam 100.

[0052] According to the anti-collision beam 100 of the utility model, the anti-collision beam 100 has a simple structure, and the production efficiency of the anti-collision beam 100 is improved. Moreover, the anti-collision beam 100 can also mitigate collisions and improve the performance of safe collisions. In addition, according to the needs, by protruding one side edge of the connecting section 2 from the first side edge 11 or the second side edge 12 of the anti-collision section 1 on the same side, the requirements of the approach angle and safety of vehicles 300 of different models can be met, so that the anti-collision beam 100 can be used on vehicles 300 of different models, which improves the commonality of the installation of the anti-collision beam 100, thereby improving the performance of the anti-collision beam 100.

[0053] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 , the first side edge 11 is recessed toward the direction where the second side edge 12 is located. Figure 3 When the anti-collision beam 100 is installed in reverse (as shown in FIG. Figure 2 As shown), the anti-collision beam 100 is suitable for MPV, that is, by rotating the anti-collision beam 100 180° in the up and down direction, it can be used on vehicles 300 of different models, which further improves the commonality of the installation of the anti-collision beam 100, improves the flexibility of the use of the anti-collision beam 100, and also improves the convenience of using the anti-collision beam 100.

[0054] According to some embodiments of the present invention, referring to Figure 3 A transition section 3 is provided between the anti-collision section 1 and the plurality of connecting sections 2, and the side of the transition section 3 located on the side where the first side 11 is located extends obliquely from the connecting section 2 toward the anti-collision section 1 toward the other side of the transition section 3. Figure 3In the example, two transition sections 3 are provided, and the two transition sections 3 are respectively located at the left and right ends of the anti-collision section 1, one end of the transition section 3 is connected to the anti-collision section 1, and the other end of the transition section 3 is connected to the connecting section 2. Among them, taking the connecting section 2 on the left side of the anti-collision section 1 as an example, the right side of the transition section 3 is connected to the left side of the anti-collision section 1, and the left side of the transition section 3 is connected to the right side of the connecting section 2. In this way, the transition section 3 strengthens the connection strength between the anti-collision section 1 and the connecting section 2, thereby improving the structural strength of the anti-collision beam 100. In addition, the transition section 3 extends obliquely, and the anti-collision section 1 is gradually transitioned to the connecting section 2 through the transition section 3, or the connecting section 2 is gradually transitioned to the anti-collision section 1, thereby further strengthening the connection strength between the anti-collision section 1 and the connecting section 2, further improving the structural strength of the anti-collision beam 100, and then further improving the performance of the anti-collision beam 100.

[0055] According to some embodiments of the present invention, referring to Figure 3 , the width of the connecting section 2 is greater than the width of the anti-collision section 1. For example, Figure 3 In the example, the width of the middle part of the anti-collision beam 100 is narrower, and the width of the left and right ends of the anti-collision beam 100 is wider. In this way, when the vehicle 300 is subjected to offset collision or other working conditions, the cross-sectional force required by the anti-collision beam 100 when it is hit is increased (that is, the ability to withstand collision is improved), thereby improving the performance of the anti-collision beam 100. In addition, the force transmission path is also slowed down (force transmission path: anti-collision beam 100-energy absorption box 201-subframe longitudinal beam 204, such as Fig.14 The collision force required by the vehicle 300 is reduced by the arrow C in the middle circle, thereby reducing the collision force on the sub-frame longitudinal beam 204, avoiding damage to the sub-frame longitudinal beam 204, and extending the service life of the vehicle 300. Moreover, during a collision, it is helpful to reduce the collision speed, delay the deformation of the sub-frame longitudinal beam 204, and is also beneficial to low-speed collision.

[0056] According to some embodiments of the present invention, referring to Figure 4 and Figure 6 , the thickness direction of the connecting section 2 (such as Figure 4 A hanging member 21 extending in a direction away from the connecting section 2 is provided on one side of the connecting section 2 (in the front-to-back direction shown in FIG. 1 ), and a free end of the hanging member 21 has a matching portion 211, and the width of the matching portion 211 is greater than the width of the hanging member 21. Figure 4 and Figure 6In the example, one end of the suspension member 21 is connected to the rear side of the connecting section 2, and the matching portion 211 is provided at the other end (i.e., the free end) of the suspension member 21. With such a configuration, when the anti-collision beam 100 is used for the subframe 200 of the vehicle 300, the suspension member 21 cooperates with the connecting plate 202 of the energy absorption box 201, so that the anti-collision beam 100 can be pre-positioned on the energy absorption box 201. When the suspension member 21 is assembled and connected with the energy absorption box 201, it is convenient for the user to lift and assemble, which reduces the difficulty of assembling the suspension member 21 and the energy absorption box 201, thereby improving the assembly efficiency of the subframe 200. In addition, the matching portion 211 limits the connecting plate 202 of the energy absorption box 201 to prevent the energy absorption box 201 from falling off the suspension member 21, strengthens the assembly of the suspension member 21 and the energy absorption box 201, and further improves the assembly stability of the subframe 200. At the same time, the configuration of vehicles 300 of different models is met, and the commonality of the anti-collision beam 100 is improved. Wherein, two suspension members 21 are provided on the anti-collision beam 100 .

[0057] According to some embodiments of the present invention, referring to Figure 4 and Figure 8 A through hole 22 is formed on one side of the connecting section 2 in the thickness direction (i.e., the front-to-back direction), and the hanging member 21 is connected to the side wall of the through hole 22. Figure 4 and Figure 8 In the example, the through hole 22 is formed on the rear side of the connecting section 2, and one end of the suspension member 21 is connected to the side wall of the through hole 22 close to the anti-collision section 1. In this way, the through hole 22 has a simple structure and is easy to produce, which improves the production efficiency of the anti-collision beam 100. Moreover, it is also convenient to connect the suspension member 21 to the connecting section 2, reducing the difficulty of producing the suspension member 21. It should be noted that the other end of the suspension member 21 first extends in a direction away from the anti-collision section 1 and then extends in a direction away from the connecting section 2.

[0058] According to some embodiments of the present invention, referring to Figure 5 and Figure 6, including a first anti-collision beam 4 and a second anti-collision beam 5, the first anti-collision beam 4 and the second anti-collision beam 5 are arranged along the thickness direction of the anti-collision beam 100 (i.e., the front-to-back direction), the first anti-collision beam 4 includes a first beam section 41 and two second beam sections 42, the first beam section 41 extends along the width direction of the anti-collision beam 100 (i.e., the up-down direction), one ends of the two second beam sections 42 are respectively connected to the two sides of the first beam section 41, and the other ends of the two second beam sections 42 extend toward the same side along the thickness direction of the anti-collision beam 100. The second anti-collision beam 5 includes a third beam section 51, a fourth beam section 52 and a fifth beam section 53. The third beam section 51 is opposite to the first beam section 41 along the thickness direction of the anti-collision beam 100, the fourth beam section 52 is respectively connected to one side of the third beam section 51 and the other end of one of the two second beam sections 42, one end of the fifth beam section 53 is connected to the other side of the third beam section 51, and the other end of the fifth beam section 53 extends obliquely along the thickness direction of the fifth beam section 53 toward the other end of the other second beam section 42 of the two second beam sections 42.

[0059] For example, in Figure 5 and Figure 6 In the example, the first anti-collision beam 4 is located at the rear side of the second anti-collision beam 5, the upper end of the first beam section 41 is connected to the rear end of one of the two second beam sections 42 (i.e., the second beam section 42 located above the first beam section 41), and the lower end of the first beam section 41 is connected to the rear end of the other of the two second beam sections 42 (i.e., the second beam section 42 located below the first beam section 41), and the cross-sectional shape of the first anti-collision segment 1 is roughly "U"-shaped. The upper end of the third beam section 51 is connected to the front end of the fourth beam section 52, and the upper side surface of the rear end of the fourth beam section 52 is connected to the lower side surface of the front end of one of the above-mentioned second beam sections 42. The lower end of the third beam section 51 is connected to the front end of the fifth beam section 53, and the rear end of the fifth beam section 53 extends in a direction from top to bottom and tilted backward, and the cross-sectional shape of the second anti-collision beam 5 is roughly trapezoidal, and the lower side surface of the rear end of the fifth beam section 53 is connected to the upper side surface of the front end of the above-mentioned other second beam section 42.

[0060] In this way, the inclined setting of the fifth beam section 53 meets the approach angle requirement of the SUV vehicle 300, improves the passability of the vehicle 300, and thus improves the performance of the vehicle 300. In addition, the safety section force is also increased, the structural strength of the anti-collision beam 100 is improved, and the anti-collision capability of the anti-collision beam 100 is improved. It should be noted that one of the second beam sections 42 is welded to the fourth beam section 52, and the other second beam section 42 is welded to the fifth beam section 53.

[0061] According to the second embodiment of the utility model, the auxiliary frame 200 is Figure 7 , including an anti-collision beam 100 according to the above-mentioned first aspect embodiment of the utility model.

[0062] According to the sub-frame 200 of the present invention, by adopting the above-mentioned anti-collision beam 100, the versatility of the sub-frame 200 is improved, and the anti-collision capability of the sub-frame 200 is also improved.

[0063] According to some embodiments of the present invention, referring to Figure 7-Figure 13 The subframe 200 further includes a plurality of energy absorption boxes 201, which are respectively connected to the plurality of connecting sections 2 of the anti-collision beam 100 through a plurality of connecting plates 202. An opening 2021 is formed on the connecting plate 202, and the opening 2021 passes through one side of the connecting plate 202 in the length direction (i.e., the left-right direction). The suspension member 21 of the anti-collision beam 100 is suitable for fitting in the opening 2021, and the fitting portion 211 of the suspension member 21 is located on the side of the connecting plate 202 away from the anti-collision beam 100.

[0064] For example, in Figure 7-Figure 13 In the example, two energy absorbing boxes 201 are provided, and the two energy absorbing boxes 201 are spaced apart in the left-right direction, two connecting plates 202 are provided, and two connecting sections 2 are provided. Each energy absorbing box 201 is connected to the connecting section 2 at the corresponding position through a connecting plate 202. The opening 2021 passes through the side surface of the connecting plate 202 away from the anti-collision section 1 in the left-right direction. The cross-sectional shape of the opening 2021 is roughly "U", and the matching portion 211 is located on the rear side of the connecting plate 202. In other words, multiple energy absorbing boxes 201, multiple connecting plates 202 and multiple connecting sections 2 are respectively matched and connected in a one-to-one correspondence. Of course, one energy absorbing box 201 can be connected to one connecting section 2 through multiple connecting plates 202, and one energy absorbing box 201 can also be connected to multiple connecting sections 2 through multiple connecting plates 202.

[0065] With such arrangement, the suspension member 21 slides into the opening 2021 along the side through which the opening 2021 passes, which reduces the difficulty of assembling the suspension member 21 and the connecting plate 202 and improves the assembly efficiency of the subframe 200. Moreover, the arrangement of the opening 2021 also ensures that the suspension can be installed regardless of whether it is an MPV or SUV structure, that is, the anti-collision beam 100 can be assembled regardless of whether it is installed forward or reverse. In addition, the matching portion 211 limits the connecting plate 202 to prevent the suspension member 21 from falling off the connecting plate 202, strengthens the assembly strength of the anti-collision beam 100 and the energy absorption box 201, prevents the anti-collision beam 100 from falling off the energy absorption box 201, and improves the stability of the subframe 200 during assembly. In addition, the pre-assembly of the energy absorption box 201 and the connecting section 2 is also achieved, which facilitates the assembly of the anti-collision beam 100 and the subframe 200.

[0066] Optionally, refer to Figure 7 , Figure 8 and Fig.11, a side of the connecting section 2 away from the energy absorption box 201 is formed with an avoidance hole 23, and the avoidance hole 23 is opposite to the energy absorption box 201 along the thickness direction of the connecting section 2. A mounting hole 2022 is formed on the connecting plate 202. The anti-collision beam 100 also includes a fastener 203, and the fastener 203 passes through the side of the connecting section 2 close to the energy absorption box 201 and the mounting hole 2022 from the avoidance hole 23. The end of the multiple energy absorption boxes 201 away from the anti-collision beam 100 is connected to the longitudinal beam 204 of the subframe 200. In this way, the avoidance hole 23 facilitates the fastener 203 to connect the connecting section 2 and the energy absorption box 201 together, reducing the difficulty of installing the fastener 203. In addition, the setting of the mounting hole 2022 facilitates the connection of the fastener 203 with the connecting plate 202, reducing the difficulty of installing the connecting section 2 and the energy absorption box 201, thereby helping to improve the installation efficiency of the subframe 200.

[0067] In addition, the structure, force transmission path and installation method of the anti-collision beam 100 are optimized, the deformation area of ​​the collision (such as the anti-collision beam 100, the energy absorption box 201 and the subframe longitudinal beam 204) is increased, the collision force is reduced, and the safety requirements are met. At the same time, the commonality of the use of the anti-collision beam 100 and the convenience of disassembly and installation are also improved, thereby improving the competitiveness of the anti-collision beam and making customers more satisfied. It should be noted that the fastener 203 can be a bolt, but is not limited to this. The cross-sectional shape of the avoidance hole 23 is a "U" shape. When the anti-collision beam 100 is installed on the SUV, the avoidance hole 23 opens downward (such as Figure 3 When the anti-collision beam 100 is installed on the MPV, the avoidance hole 23 is opened upward (as shown in FIG. Figure 2 shown).

[0068] According to the vehicle 300 of the third embodiment of the utility model, Fig.14 , including a subframe 200 according to the above-mentioned second aspect embodiment of the utility model.
