[0034] Next, with reference to the drawings, the longitudinal beam structure 100 according to an embodiment of the present invention will be described.

[0035] As Figures 1 - 5 shown, the longitudinal beam structure 100 according to an embodiment of the present invention includes: an outer longitudinal beam plate 1, an inner longitudinal beam plate 2, a mounting sleeve 3 and a reinforcing plate assembly 4. The inner longitudinal beam plate 2 is connected to the outer longitudinal beam plate 1 to define a mounting cavity; the mounting sleeve 3 is located in the mounting cavity and is connected to the inner longitudinal beam plate 2, and the mounting sleeve 3 is used for mounting a subframe; the reinforcing plate assembly 4 is located in the mounting cavity and is connected to the inner longitudinal beam plate 2. The reinforcing plate assembly 4 includes a front reinforcing plate 41 and a rear reinforcing plate 42, and the front reinforcing plate 41 and the rear reinforcing plate 42 are clamped on the front and rear sides of the mounting sleeve 3.

[0036] Thereby, the mounting stability of the mounting sleeve 3 can be improved, and the structural stability of the inner longitudinal beam plate 2 can also be improved, which is beneficial to improving the stiffness of the subframe mounting point and enhancing the reliability of the inner longitudinal beam plate 2.

[0037] For example, as Figures 1 - 4 shown, the longitudinal beam structure 100 includes an outer longitudinal beam plate 1, an inner longitudinal beam plate 2 and a mounting sleeve 3. The outer longitudinal beam plate 1 is disposed on the inner longitudinal beam plate 2 along the vehicle body transverse direction (i.e., Figure 3On the outer side in the left - right direction (as shown), the outer panel 1 of the longitudinal beam can be welded to the inner panel 2 of the longitudinal beam to define an installation cavity. The installation sleeve 3 is located in the installation cavity and is connected to the inner panel 2 of the longitudinal beam. The installation sleeve 3 has a threaded installation cavity, and a through - hole is provided on the inner panel 2 of the longitudinal beam corresponding to the threaded installation cavity. The connecting piece can penetrate through the sub - frame and extend into the threaded installation cavity through the through - hole to fix the sub - frame on the installation sleeve 3. Exemplarily, the longitudinal beam structure 100 can be set as the front section of the vehicle body longitudinal beam, and the sub - frame can be set as the front sub - frame.

[0038] Wherein, the longitudinal beam structure 100 further includes a reinforcing plate assembly 4. The reinforcing plate assembly 4 is located in the installation cavity and is connected to the inner panel 2 of the longitudinal beam. The reinforcing plate assembly 4 includes a front reinforcing plate 41 and a rear reinforcing plate 42. Both the front reinforcing plate 41 and the rear reinforcing plate 42 are connected to the inner panel 2 of the longitudinal beam to support the inner panel 2 of the longitudinal beam. The front reinforcing plate 41 is located on the front side of the installation sleeve 3, and the rear reinforcing plate 42 is located on the rear side of the installation sleeve 3, so that the front reinforcing plate 41 and the rear reinforcing plate 42 are clamped on the front and rear sides of the installation sleeve 3 to support the installation sleeve 3 from the front and rear sides. Thus, it is beneficial to improve the stability of the installation sleeve 3, thereby improving the stiffness of the sub - frame mounting point. Moreover, the structures of the front reinforcing plate 41 and the rear reinforcing plate 42 are simple and the installation is convenient, which is conducive to reducing the assembly difficulty of the longitudinal beam structure 100.

[0039] According to the longitudinal beam structure 100 of the embodiment of the present invention, by setting the front reinforcing plate 41 and the rear reinforcing plate 42, the installation sleeve 3 can be limited and supported from the front and rear sides, improving the installation stability of the installation sleeve 3. Moreover, the front reinforcing plate 41 and the rear reinforcing plate 42 can also support the inner panel 2 of the longitudinal beam to improve the structural stability of the inner panel 2 of the longitudinal beam, which is beneficial to improving the stiffness of the sub - frame mounting point and enhancing the reliability of the longitudinal beam structure 100.

[0040] In some embodiments of the present invention, the inner panel 2 of the longitudinal beam includes an inner panel main body 21, an upper side panel 22 and a lower side panel 23 provided on the vertical two sides of the inner panel main body 21. The upper side panel 22 and the lower side panel 23 are respectively connected to the outer panel 1 of the longitudinal beam. The front reinforcing plate 41 and / or the rear reinforcing plate 42 are adapted to be connected to at least two of the inner panel main body 21, the upper side panel 22 and the lower side panel 23.

[0041] For example, referring to Figures 2 - 3As shown, the inner panel 2 of the longitudinal beam includes an inner panel main body 21, an upper side panel 22, and a lower side panel 23. The inner panel main body 21 extends vertically. The upper side panel 22 is connected to the upper side in the vertical direction of the inner panel main body 21 and extends in a direction close to the outer panel 1 of the longitudinal beam. The upper side panel 22 is provided with an upward flanging 221. The lower side panel 23 is connected to the lower side in the vertical direction of the inner panel main body 21 and extends in a direction close to the outer panel 1 of the longitudinal beam. The lower side panel 23 is provided with a downward flanging 231. The upward flanging 221 and the downward flanging 231 are used to be respectively connected to both sides in the vertical direction of the outer panel 1 of the longitudinal beam, so that the outer panel 1 of the longitudinal beam, the upper side panel 22, the inner panel main body 21, and the lower side panel 23 can jointly define an installation cavity.

[0042] Among them, first connection flanges 411 can be respectively provided on at least two sides of the front reinforcement plate 41, so that the front reinforcement plate 41 can be connected to at least two of the inner panel main body 21, the upper side panel 22, and the lower side panel 23 through the first connection flanges 411; or, second connection flanges 421 can be respectively provided on at least two sides of the rear reinforcement plate 42, so that the rear reinforcement plate 42 can be connected to at least two of the inner panel main body 21, the upper side panel 22, and the lower side panel 23 through the second connection flanges 421; or, first connection flanges 411 can be respectively provided on at least two sides of the front reinforcement plate 41, and second connection flanges 421 can be respectively provided on at least two sides of the rear reinforcement plate 42, so that the front reinforcement plate 41 can be connected to at least two of the inner panel main body 21, the upper side panel 22, and the lower side panel 23 through the first connection flanges 411, and the rear reinforcement plate 42 can be connected to at least two of the inner panel main body 21, the upper side panel 22, and the lower side panel 23 through the second connection flanges 421.

[0043] It should be noted that the first connection flanges 411 and the second connection flanges 421 can be welded to the inner panel 2 of the longitudinal beam, such as by CO2 shielded welding.

[0044] Preferably, first connection flanges 411 can be respectively provided on the upper side, the inner side, and the lower side of the front reinforcement plate 41, so that the front reinforcement plate 41 can be respectively connected to the upper side panel 22, the inner panel main body 21, and the lower side panel 23 through the first connection flanges 411, and second connection flanges 421 can be respectively provided on the upper side, the inner side (the side close to the inner panel 2 of the longitudinal beam), and the lower side of the rear reinforcement plate 42, so that the rear reinforcement plate 42 can be respectively connected to the upper side panel 22, the inner panel main body 21, and the lower side panel 23 through the second connection flanges 421

[0045] Through the above settings, the installation stability of the front reinforcement plate 41 and the rear reinforcement plate 42 can be improved, which is beneficial to improving the limiting effect of the front reinforcement plate 41 and the rear reinforcement plate 42 on the installation sleeve 3, and the structural stability of the inner panel 2 of the longitudinal beam can be improved, which is beneficial to improving the stiffness of the subframe installation point.

[0046] In some embodiments of the present invention, such as Figure 4As shown, a first reinforcing flange 412 can be provided on the side of the front reinforcing plate 41 facing the longitudinal beam outer plate 1. The first reinforcing flange 412 is arranged opposite to the longitudinal beam outer plate 1 and is used to enhance the structural strength of the front reinforcing plate 41. This helps to improve the limiting support effect of the front reinforcing plate 41.

[0047] In some embodiments of the present invention, Figure 4 As shown, a second reinforcing flange 422 can be provided on the side of the rear reinforcing plate 42 facing the longitudinal beam outer plate 1. The second reinforcing flange 422 is arranged opposite to the longitudinal beam outer plate 1 and is used to enhance the structural strength of the rear reinforcing plate 42. This helps to improve the limiting support effect of the rear reinforcing plate 42.

[0048] In some embodiments of the present invention, the front reinforcing plate 41 and the rear reinforcing plate 42 are welded together and jointly define an enclosed space, and the mounting sleeve 3 extends into the enclosed space.

[0049] For example, refer to Figures 3 - 4 As shown, the front reinforcing plate 41 and the rear reinforcing plate 42 are both arranged to extend in the left-right direction and face each other in the front-to-back direction. Each of the front reinforcing plate 41 and the rear reinforcing plate 42 is provided with a semi-enclosed groove 410. The front reinforcing plate 41 and the rear reinforcing plate 42 are welded (e.g., spot welded) to each other, and an open enclosed space is defined at the semi-enclosed groove 410. The mounting sleeve 3 is arranged to match the enclosed space, extending into the enclosed space and engaging with the front reinforcing plate 41 and the rear reinforcing plate 42, respectively. Preferably, the semi-enclosed groove 410 can be provided in the middle of the front reinforcing plate 41 and the rear reinforcing plate 42 in the left-to-right direction.

[0050] Through the above arrangement, the relative stability between the front reinforcing plate 41 and the rear reinforcing plate 42 can be improved to ensure the limiting support effect of the front reinforcing plate 41 and the rear reinforcing plate 42 and improve the hardness of the subframe mounting point.

[0051] Further, if Figure 4 As shown, a welding boss 423 can be provided on the rear reinforcing plate 42. The welding boss 423 protrudes forward, and the rear reinforcing plate 42 can be welded to the front reinforcing plate 41 via the welding boss 423. Of course, the front reinforcing plate 41 can also be provided with a rearward-protruding welding boss 423, which is not limited in this application. This arrangement can avoid large-area contact between the front reinforcing plate 41 and the rear reinforcing plate 42, helping to eliminate the risk of shaking and abnormal noise caused by excessive load, and also helping to improve the electrophoresis effect.

[0052] In some embodiments of the present invention, the reinforcing plate assembly 4 further includes a lower reinforcing plate 43 , the mounting sleeve 3 is connected to the side of the lower reinforcing plate 43 facing away from the longitudinal beam inner plate 2 , and at least one of the front reinforcing plate 41 and the rear reinforcing plate 42 is connected to the lower reinforcing plate 43 .

[0053] For example, with reference to Figures 2 - 3 As shown, the reinforcing plate assembly 4 further includes a lower reinforcing plate 43. The lower reinforcing plate 43 is arranged to extend in the front-rear direction. The lower reinforcing plate 43 is connected to the inner longitudinal beam plate 2 and is used to support the inner longitudinal beam plate 2. The mounting sleeve 3 is connected (such as by MIG welding) to the side of the lower reinforcing plate 43 facing away from the inner longitudinal beam plate 2. An avoidance hole is provided on the lower reinforcing plate 43. The connecting piece can pass through the subframe and pass through the through hole and the avoidance hole to extend into the threaded mounting cavity, so as to fix the subframe on the mounting sleeve 3.

[0054] Wherein, at least part of the front reinforcing plate 41 can be set to be connected to the lower reinforcing plate 43; or, at least part of the rear reinforcing plate 42 can be set to be connected to the lower reinforcing plate 43; or, at least part of the front reinforcing plate 41 can be set to be connected to the lower reinforcing plate 43, and at least part of the rear reinforcing plate 42 can be set to be connected to the lower reinforcing plate 43. So that the lower reinforcing plate 43 can be connected to the front reinforcing plate 41 and the rear reinforcing plate 42 to form a T-shaped structure, enhancing the anti-deformation ability of the longitudinal beam structure 100 and improving the stability of the mounting sleeve 3. Thus, it is beneficial to improve the reliability of the longitudinal beam structure 100.

[0055] In some embodiments of the present invention, the inner longitudinal beam plate 2 includes an inner plate main body 21 and a lower side plate 23 provided on the vertical lower side of the inner plate main body 21. The lower reinforcing plate 43 includes a main body portion 431 and a connecting portion 432. The main body portion 431 is connected to the lower side plate 23, the connecting portion 432 is connected to the inner plate main body 21, and the mounting sleeve 3 is connected to the main body portion 431.

[0056] For example, with reference to Figures 2 - 4 As shown, the inner longitudinal beam plate 2 includes an inner plate main body 21, an upper side plate 22 and a lower side plate 23. The inner plate main body 21 extends vertically. The upper side plate 22 is connected to the vertical upper side of the inner plate main body 21 and extends towards the side close to the outer longitudinal beam plate 1. The upper side plate 22 is provided with an upward flange 221. The lower side plate 23 is connected to the vertical lower side of the inner plate main body 21 and extends towards the side close to the outer longitudinal beam plate 1. The lower side plate 23 is provided with a downward flange 231. The upward flange 221 and the downward flange 231 are used to be connected to the two sides of the outer longitudinal beam plate 1 in the vertical direction respectively, so that the outer longitudinal beam plate 1, the upper side plate 22, the inner plate main body 21 and the lower side plate 23 can jointly define an installation cavity.

[0057] The lower reinforcing plate 43 includes a main body portion 431 and a connecting portion 432. The connecting portion 432 is bent and connected to one side of the main body portion 431 in the width direction. The main body portion 431 is used to be welded to the lower side plate 23, and the connecting portion 432 is used to be welded to the inner plate main body 21 to fix the lower reinforcing plate 43 on the inner longitudinal beam plate 2, and the mounting sleeve 3 is adapted to be connected to the main body portion 431. Through the above settings, the installation stability of the lower reinforcing plate 43 can be improved, which is beneficial to the installation stability of the mounting sleeve 3.

[0058] Further, as Figures 2 - 3 shown, a lower connecting flange 433 can be provided on the other side of the main body portion 431 away from the connecting portion 432. The lower connecting flange 433 is used to extend to the side of the lower side plate 23 facing the longitudinal beam outer plate 1. When the longitudinal beam outer plate 1 is installed onto the longitudinal beam inner plate 2, the lower connecting flange 433 can be clamped between the lower flanges 231 of the longitudinal beam outer plate 1 and the longitudinal beam inner plate 2, and is respectively welded to the longitudinal beam outer plate 1 and the longitudinal beam inner plate 2. Thereby, the structural strength and installation stability of the lower reinforcing plate 43 can be improved, which is beneficial to improving the supporting effect of the lower reinforcing plate 43 on the mounting sleeve 3.

[0059] In some embodiments of the present invention, the reinforcing plate assembly 4 further includes an upper reinforcing plate 44. The upper reinforcing plate 44 is located on the front side of the front reinforcing plate 41 and is connected to the rear end of the front reinforcing plate 41. The upper reinforcing plate 44 is provided with a first reinforcing rib 443 extending in the front-rear direction.

[0060] For example, referring to Figures 3 - 5 shown, the reinforcing plate assembly 4 further includes an upper reinforcing plate 44. The upper reinforcing plate 44 is connected to the longitudinal beam inner plate 2 and is used to support the longitudinal beam inner plate 2. The upper reinforcing plate 44 is arranged to extend in the front-rear direction. The upper reinforcing plate 44 is located on the front side of the front reinforcing plate 41 and the rear end is used to be connected to the front reinforcing plate 41 for supporting the front reinforcing plate 41. Meanwhile, a first reinforcing rib 443 can be provided on the upper reinforcing plate 44. The first reinforcing rib 443 extends in the front-rear direction and is parallel to the force transmission channel of the longitudinal beam structure 100.

[0061] It can be understood that by setting the rear end of the upper reinforcing plate 44 to be connected to the front reinforcing plate 41, the longitudinal beam structure 100 can be designed to be weaker in the front and stronger in the rear, so as to ensure that the longitudinal beam structure 100 can absorb more impact force during a collision, and the installation stability of the upper reinforcing plate 44 can be improved, which is beneficial to improving the stiffness of the subframe mounting point.

[0062] In some embodiments of the present invention, the upper reinforcing plate 44 is provided with a positioning boss 444 connected to the first reinforcing rib 443. The positioning boss 444 is provided with a positioning hole 445, and the positioning hole 445 is adapted to be in positioning cooperation with the longitudinal beam inner plate 2.

[0063] For example, referring to Figures 3 - 5 shown, the upper reinforcing plate 44 is provided with a positioning boss 444. The positioning boss 444 protrudes in a direction away from the longitudinal beam inner plate 2. The first reinforcing rib 443 is connected to the positioning boss 444. For example, the positioning boss 444 can be connected to the end of the first reinforcing rib 443 so that the first reinforcing rib 443 can support the positioning boss 444.

[0064] The positioning bosses 444 are provided with at least two, and the at least two positioning bosses 444 are spaced apart in the front-rear direction. A positioning hole 445 is provided on the positioning boss 444, and a positioning portion is provided on the inner wall of the inner panel 2 of the longitudinal beam. The positioning portion can be configured as a positioning post. The positioning hole 445 is used for positioning and cooperating with the positioning portion to achieve precise positioning between the upper reinforcement plate 44 and the inner panel 2 of the longitudinal beam. Thus, it is beneficial to reduce the installation difficulty of the upper reinforcement plate 44.

[0065] Further, as Figure 5 shown, special-shaped holes 446, such as rectangular holes, can be respectively formed in the positioning boss 444 and the first reinforcing rib 443. Thus, lightweight design of the upper reinforcement plate 44 can be achieved, and the electrophoresis effect of the upper reinforcement plate 44 can be ensured.

[0066] In some embodiments of the present invention, the inner panel 2 of the longitudinal beam includes an inner panel main body 21 and an upper side panel 22 provided on the upper side in the vertical direction of the inner panel main body 21. The upper reinforcement plate 44 is respectively connected to the upper side panel 22 and the inner panel main body 21.

[0067] For example, referring to Figures 3 - 5 shown, the inner panel 2 of the longitudinal beam includes an inner panel main body 21, an upper side panel 22 and a lower side panel 23. The inner panel main body 21 extends in the vertical direction. The upper side panel 22 is connected to the upper side in the vertical direction of the inner panel main body 21 and extends in a direction close to the outer panel 1 of the longitudinal beam. The upper side panel 22 is provided with an upward flanging 221. The lower side panel 23 is connected to the lower side in the vertical direction of the inner panel main body 21 and extends in a direction close to the outer panel 1 of the longitudinal beam. The lower side panel 23 is provided with a downward flanging 231. The upward flanging 221 and the downward flanging 231 are respectively used for connecting with both sides in the vertical direction of the outer panel 1 of the longitudinal beam, so that the outer panel 1 of the longitudinal beam, the upper side panel 22, the inner panel main body 21 and the lower side panel 23 can jointly define an installation cavity.

[0068] Among them, the upper reinforcement plate 44 can be provided to include a first part 441 and a second part 442 that are bent and connected. The first part 441 is used for welded connection with the inner panel main body 21, and the second part 442 is used for welded connection with the upper side panel 22. It should be noted that the first part 441 and the second part 442 are respectively spot-welded to the inner panel 2 of the longitudinal beam. Thus, the installation stability of the upper reinforcement plate 44 can be improved, which is beneficial to improving the support effect of the upper reinforcement plate 44 on the inner panel 2 of the longitudinal beam.

[0069] In some embodiments of the present invention, as Figure 1 shown, a second reinforcing rib 11 can be provided on the outer panel 1 of the longitudinal beam. The second reinforcing rib 11 extends in the front-rear direction to be parallel to the force transmission channel of the longitudinal beam structure 100. Thus, the anti-deformation ability of the longitudinal beam structure 100 can be improved, which is beneficial to reducing the deformation amplitude of the longitudinal beam structure 100 during a collision.
