[0027] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.
[0028] See the figure below for reference Figure 1-Figure 3 The front wheel house side beam assembly 100 according to the embodiment of the present invention is described. The front wheel house side beam assembly 100 according to the embodiment of the present invention can be applied to a vehicle.
[0029] Combination Figure 1-Figure 3 As shown, the front wheel housing side beam assembly 100 according to the embodiment of the utility model can mainly include: a side beam inner plate 10 and a side beam outer plate 20, wherein the lower end of the side beam inner plate 10 is suitable for connecting with the front wheel housing 200. Specifically, the side beam outer plate 20 is arranged on the outer side of the side beam inner plate 10, so that the side beam inner plate 10 and the side beam outer plate 20 can constitute the basic structure of the front wheel housing side beam assembly 100, and the side beam inner plate 10 and the side beam outer plate 20 play the role of bearing the front end components of the vehicle and transmitting force and absorbing energy in collision in the front wheel housing side beam assembly 100.
[0030] Further, the side beam inner plate 10 and the side beam outer plate 20 are both in a "J" shape, the side beam inner plate 10 at least partially protrudes inward relative to the side beam outer plate 20, and the side beam outer plate 20 at least partially protrudes outward relative to the side beam inner plate 10. Specifically, the side beam inner plate 10 is arranged close to the inner side of the side beam outer plate 20, and the side beam outer plate 20 is arranged close to the outer side of the side beam inner plate 10.
[0031] Furthermore, the side beam inner plate 10 is at least partially protruded inward relative to the side beam outer plate 20, so that the side beam inner plate 10 is arranged in a "X" shape, and the "X"-shaped structure has high torsional rigidity and bending rigidity, which can improve the structural rigidity of the side beam inner plate 10. The side beam outer plate 20 is at least partially protruded outward relative to the side beam inner plate 10, so that the side beam outer plate 20 is arranged in a "X" shape, and the "X"-shaped structure has high torsional rigidity and bending rigidity, which can improve the structural rigidity of the side beam outer plate 20. In this way, the strength of the front wheel housing side beam assembly 100 can be improved.
[0032] In the embodiment of the utility model, by changing the structure of the side beam inner plate 10 and the side beam outer plate 20 to improve the strength of the front wheel housing side beam assembly 100, the bearing capacity of the front wheel housing side beam assembly 100 can be improved. Compared with the prior art, under the premise of meeting the strength design requirements of the front wheel housing side beam assembly 100, the sheet thickness of the front wheel housing side beam assembly 100 can be reduced, thereby reducing the development cost, achieving the dual optimization effect of reducing cost and increasing efficiency.
[0033] Combination Figure 2 As shown, the side beam inner plate 10 includes a first inner plate 11, a second inner plate 12 and a third inner plate 13. The first inner plate 11 is extended in the up and down directions, and the second inner plate 12 and the third inner plate 13 are respectively arranged at the upper and lower ends of the first inner plate 11. The second inner plate 12 and the third inner plate 13 are both bent and extended toward the outside relative to the first inner plate 11.
[0034] Specifically, the first inner plate 11 in the side beam inner plate 10 extends up and down, and can bear the force transmitted in the up and down directions. The second inner plate 12 and the third inner plate 13 are respectively located at the upper and lower ends of the first inner plate 11, and the second inner plate 12 is connected to the end of the first inner plate 11 away from the third inner plate 13, and the third inner plate 13 is connected to the end of the first inner plate 11 away from the second inner plate 12, so that the force can be transmitted between the second inner plate 12, the first inner plate 11 and the third inner plate 13. Compared with the prior art, the transmission path of the force on the side beam inner plate 10 can be increased, and the force transmission effect of the side beam inner plate 10 can be optimized.
[0035] Furthermore, the second inner plate 12 is bent and extended outward relative to the first inner plate 11, so that the direction of force transmission on the side beam inner plate 10 can be changed, and the force can be transmitted in the inner and outer directions on the side beam inner plate 10. In addition, the second inner plate 12 extends outward, so that the second inner plate 12 can be arranged close to the side beam outer plate 20, so as to facilitate the connection between the side beam inner plate 10 and the outer edge of the side beam.
[0036] Furthermore, the third inner plate 13 is bent and extended outward relative to the first inner plate 11, so that the direction of force transmission on the side beam inner plate 10 can be changed, and the force can be transmitted in the inner and outer directions on the side beam inner plate 10. In addition, the third inner plate 13 extends outward, so that the third inner plate 13 can be arranged close to the side beam outer plate 20, so as to facilitate the connection between the side beam inner plate 10 and the outer edge of the side beam.
[0037] Furthermore, the second inner plate 12 and the third inner plate 13 are both bent and extended outward relative to the first inner plate 11, so as to form a "J"-shaped structure of the side beam inner plate 10. Such a configuration can increase the transmission path and direction of the force on the side beam inner plate 10, thereby enhancing the torsional stiffness and bending stiffness of the side beam inner plate 10, which is beneficial to improving the strength performance of the front wheel cover side beam assembly 100.
[0038] Combination Figure 2 As shown, the side beam outer plate 20 includes a first outer plate 21, a second outer plate 22 and a third outer plate 23. The first outer plate 21 is extended in the up and down directions, and the second outer plate 22 and the third outer plate 23 are respectively arranged at the upper and lower ends of the first outer plate 21. The second outer plate 22 and the third outer plate 23 are both bent and extended toward the inside relative to the first outer plate 21.
[0039] Specifically, the first outer plate 21 in the side beam outer plate 20 extends up and down, and can bear the force transmitted in the up and down directions. The second outer plate 22 and the third outer plate 23 are respectively located at the upper and lower ends of the first outer plate 21, and the second outer plate 22 is connected to the end of the first outer plate 21 away from the third outer plate 23, and the third outer plate 23 is connected to the end of the first outer plate 21 away from the second outer plate 22, so that the force can be transmitted between the second outer plate 22, the first outer plate 21 and the third outer plate 23. Compared with the prior art, the transmission path of the force on the side beam outer plate 20 can be increased, and the force transmission effect of the side beam outer plate 20 can be optimized.
[0040] Furthermore, the second outer plate 22 is bent and extended inward relative to the first outer plate 21, so that the direction of force transmission on the side beam outer plate 20 can be changed, and the force can be transmitted in the inner and outer directions on the side beam outer plate 20. In addition, the second outer plate 22 extends inward, so that the second outer plate 22 can be arranged close to the side beam outer plate 20, so as to facilitate the connection between the side beam outer plate 20 and the outer edge of the side beam.
[0041] Furthermore, the third outer plate 23 is bent and extended inward relative to the first outer plate 21, so that the direction of force transmission on the side beam outer plate 20 can be changed, and the force can be transmitted in the inner and outer directions on the side beam outer plate 20. In addition, the third outer plate 23 extends inward, so that the third outer plate 23 can be arranged close to the side beam outer plate 20, so as to facilitate the connection between the side beam outer plate 20 and the outer edge of the side beam.
[0042] Furthermore, the second outer panel 22 and the third outer panel 23 are both bent and extended inward relative to the first outer panel 21, so as to form a "J"-shaped structure of the side beam outer panel 20. Such a configuration can increase the transmission path and direction of the force on the side beam outer panel 20, thereby enhancing the torsional stiffness and bending stiffness of the side beam outer panel 20, which is beneficial to improving the strength performance of the front wheel cover side beam assembly 100.
[0043] Combination Figure 2 As shown, in an embodiment of the utility model, the side beam inner plate 10 and the side beam outer plate 20 are both in a "J" shape, so that the first inner plate 11 and the first outer plate 21 are arranged relative to each other in the inner and outer directions, the second inner plate 12 and the second outer plate 22 are arranged relative to each other in the inner and outer directions, and the third inner plate 13 and the third outer plate 23 are arranged relative to each other in the inner and outer directions. By so arranging, the structural stability of the front wheel cover side beam assembly 100 can be ensured.
[0044] Furthermore, one end of the second inner panel 12 away from the first inner panel 11 is connected to one end of the second outer panel 22 away from the first outer panel 21, and one end of the third inner panel 13 away from the first inner panel 11 is connected to one end of the third outer panel 23 away from the first outer panel 21. By such an arrangement, the upper and lower ends of the side beam inner panel 10 and the side beam outer panel 20 can be connected to form the basic structure of the double-X shape of the front wheel cover side beam assembly 100.
[0045] Combination Figure 2 As shown, the vertical wall draft angle of the second inner panel 12 is α, and α satisfies the relationship: α<10°, and the sum of the vertical wall draft angles of the second inner panel 12 and the third inner panel 13 is β, and β satisfies the relationship: β>30°.
[0046] Specifically, the side beam inner panel 10 has many vertical wall lap joints, so it is necessary to set the vertical wall draft angle of the side beam inner panel 10. In the embodiment of the utility model, if the vertical wall draft angle of the second inner panel 12 is set to be not less than 10°, the connectivity of the hood hinge and the connecting beam in the vertical direction cannot be guaranteed. Therefore, it is necessary to set the vertical wall draft angle of the second inner panel 12 to be less than 10°.
[0047] Furthermore, if the sum of the vertical wall draft angles of the second inner panel 12 and the third inner panel 13 is set to be no more than 30°, the process difficulty of manufacturing the side beam inner panel 10 will increase. In this way, in the embodiment of the utility model, the sum of the vertical wall draft angles of the second inner panel 12 and the third inner panel 13 is set to be more than 30°, which is conducive to ensuring the formability of the side beam inner panel 10.
[0048] According to an embodiment of the utility model, the sum of the vertical wall draft angles of the second outer panel 22 and the third outer panel 23 is γ, and γ satisfies the relationship: γ>30°. Specifically, the vertical wall lap joints of the side beam outer panel 20 are relatively large, so it is necessary to set the vertical wall draft angles of the side beam outer panel 20. In an embodiment of the utility model, if the sum of the vertical wall draft angles of the second outer panel 22 and the third outer panel 23 is set to be no more than 30°, the process difficulty of manufacturing the side beam outer panel 20 will increase. In this way, setting the sum of the vertical wall draft angles of the second outer panel 22 and the third outer panel 23 to exceed 30° is conducive to ensuring the formability of the side beam outer panel 20.
[0049] Combination Figure 2 and Figure 3As shown, a first arc transition plate 14 is connected between the second inner plate 12 and the first inner plate 11, and the first arc transition plate 14 can improve the connection strength between the second inner plate 12 and the first inner plate 11, and can reduce the stress concentration at the connection between the second inner plate 12 and the first inner plate 11. A second arc transition plate 15 is connected between the third inner plate 13 and the first inner plate 11, and the second arc transition plate 15 can improve the connection strength between the third inner plate 13 and the first inner plate 11, and can reduce the stress concentration at the connection between the third inner plate 13 and the first inner plate 11. A third arc transition plate 24 is connected between the second outer plate 22 and the first outer plate 21, and the third arc transition plate 24 can improve the connection strength between the second outer plate 22 and the first outer plate 21, and can reduce the stress concentration at the connection between the second outer plate 22 and the first outer plate 21. A fourth arc transition plate 25 is connected between the third outer plate 23 and the first outer plate 21 , and the fourth arc transition plate 25 can improve the connection strength between the third outer plate 23 and the first outer plate 21 , and can reduce stress concentration at the connection between the third outer plate 23 and the first outer plate 21 .
[0050] Furthermore, the radius of the circles corresponding to the first arc transition plate 14 , the second arc transition plate 15 , the third arc transition plate 24 and the fourth arc transition plate 25 is R, and R satisfies the relationship: 8 mm<R<12 mm.
[0051] Specifically, if the radius of the circle corresponding to the first arc transition plate 14, the second arc transition plate 15, the third arc transition plate 24 and the fourth arc transition plate 25 in the utility model is set to not exceed 8 mm, the first arc transition plate 14, the second arc transition plate 15, the third arc transition plate 24 and the fourth arc transition plate 25 are prone to stress concentration. In order to ensure the structural strength of the first arc transition plate 14, the second arc transition plate 15, the third arc transition plate 24 and the fourth arc transition plate 25, it is necessary to set the radius of the circle corresponding to the first arc transition plate 14, the second arc transition plate 15, the third arc transition plate 24 and the fourth arc transition plate 25 to be greater than 8 mm.
[0052] If the radius of the circle corresponding to the first arc transition plate 14, the second arc transition plate 15, the third arc transition plate 24 and the fourth arc transition plate 25 in the utility model is set to be not less than 12 mm, the structural strength of the first arc transition plate 14, the second arc transition plate 15, the third arc transition plate 24 and the fourth arc transition plate 25 will be low and easy to break. In order to ensure the structural reliability of the first arc transition plate 14, the second arc transition plate 15, the third arc transition plate 24 and the fourth arc transition plate 25, it is necessary to set the radius of the circle corresponding to the first arc transition plate 14, the second arc transition plate 15, the third arc transition plate 24 and the fourth arc transition plate 25 to be less than 12 mm.
[0053] In the embodiment of the utility model, the radius of the circle corresponding to the first arc transition plate 14, the second arc transition plate 15, the third arc transition plate 24 and the fourth arc transition plate 25 is set to R, and R satisfies the relationship: 10mm≤R<12mm.
[0054] Combination Figure 2 As shown, the side beam inner plate 10 also includes a fourth inner plate 16 and a fifth inner plate 17. The fourth inner plate 16 is arranged at one end of the second inner plate 12 away from the first inner plate 11 and extends in the up and down directions. The fifth inner plate 17 is arranged at one end of the third inner plate 13 away from the first inner plate 11 and extends in the up and down directions.
[0055] Specifically, the fourth inner plate 16 and the fifth inner plate 17 both extend in the up-down direction, so that the force in the side beam inner plate 10 can be transmitted in the up-down direction on the fourth inner plate 16 and the fifth inner plate 17, so that the force transmission path on the side beam inner plate 10 can be increased, and the force transmission effect of the side beam inner plate 10 can be optimized. Among them, the fourth inner plate 16 is connected to the end of the second inner plate 12 away from the first inner plate 11, and the fifth inner plate 17 is connected to the end of the third inner plate 13 away from the first inner plate 11, so that the force can be transmitted between the fourth inner plate 16 and the second inner plate 12, and the force can be transmitted between the fifth inner plate 17 and the third inner plate 13. With such a configuration, on the side beam inner plate 10, the fourth inner plate 16, the second inner plate 12, the first inner plate 11, the third inner plate 13 and the fifth inner plate 17 can all be used for force transmission.
[0056] Furthermore, combined with Figure 2 As shown, the side beam outer plate 20 also includes a fourth outer plate 26 and a fifth outer plate 27. The fourth outer plate 26 is arranged at one end of the second outer plate 22 away from the first outer plate 21 and is extended in the up and down directions. The fifth outer plate 27 is arranged at one end of the third outer plate 23 away from the first outer plate 21 and is extended in the up and down directions.
[0057] Specifically, the fourth outer panel 26 and the fifth outer panel 27 both extend in the up-down direction, so that the force in the side beam outer panel 20 can be transmitted in the up-down direction on the fourth outer panel 26 and the fifth outer panel 27, so that the force transmission path on the side beam outer panel 20 can be increased, and the force transmission effect of the side beam outer panel 20 can be optimized. Among them, the fourth outer panel 26 is connected to the end of the second outer panel 22 away from the first outer panel 21, and the fifth outer panel 27 is connected to the end of the third outer panel 23 away from the first outer panel 21, so that the force can be transmitted between the fourth outer panel 26 and the second outer panel 22, and the force can be transmitted between the fifth outer panel 27 and the third outer panel 23. In this way, on the side beam outer panel 20, the fourth outer panel 26, the second outer panel 22, the first outer panel 21, the third outer panel 23 and the fifth outer panel 27 can all be used for force transmission.
[0058] Furthermore, the fourth inner plate 16 and the fourth outer plate 26 are fitted together and connected and fixed, and the fifth inner plate 17 and the fifth outer plate 27 are fitted together and connected and fixed. Specifically, the fourth inner plate 16 and the fourth outer plate 26 are fitted together and fixed, so that the upper ends of the side beam inner plate 10 and the side beam outer plate 20 can be connected. The fifth inner plate 17 and the fifth outer plate 27 are fitted together and fixed, so that the lower ends of the side beam inner plate 10 and the side beam outer plate 20 can be connected. With such an arrangement, the side beam inner plate 10 and the side beam outer plate 20 in the front wheel cover side beam assembly 100 can be subjected to force at the same time, so as to improve the strength performance of the front wheel cover side beam assembly 100.
[0059] When the force is transmitted to the side beam inner plate 10 through one of the fourth inner plate 16 and the fifth inner plate 17, it can be transmitted in the up-down direction or in the in-out direction through the fourth inner plate 16, the second inner plate 12, the first inner plate 11, the third inner plate 13 and the fifth inner plate 17. When the force is transmitted to the side beam outer plate 20 through one of the fourth outer plate 26 and the fifth outer plate 27, it can be transmitted in the up-down direction or in the in-out direction through the fourth outer plate 26, the second outer plate 22, the first outer plate 21, the third outer plate 23 and the fifth outer plate 27. Therefore, in the double-X-shaped front wheel cover side beam assembly 100 of the utility model, there are more force transmission paths and transmission directions, the front wheel cover side beam assembly 100 has a better force transmission effect, and the forces in the front-to-back direction and the in-out direction can be effectively transmitted to the wheel cover inner plate and even the entire vehicle body.
[0060] Combination Figure 2 and Figure 3 As shown, a fifth arc transition plate 18 is connected between the fourth inner plate 16 and the second inner plate 12, and the fifth arc transition plate 18 can improve the connection strength between the fourth inner plate 16 and the second inner plate 12, and can reduce the stress concentration at the connection between the fourth inner plate 16 and the second inner plate 12. A sixth arc transition plate 19 is connected between the fifth inner plate 17 and the third inner plate 13, and the sixth arc transition plate 19 can improve the connection strength between the fifth inner plate 17 and the third inner plate 13, and can reduce the stress concentration at the connection between the fifth inner plate 17 and the third inner plate 13. A seventh arc transition plate 28 is connected between the fourth outer plate 26 and the second outer plate 22, and the seventh arc transition plate 28 can improve the connection strength between the fourth outer plate 26 and the second outer plate 22, and can reduce the stress concentration at the connection between the fourth outer plate 26 and the second outer plate 22. An eighth arc transition plate 29 is connected between the fifth outer panel 27 and the third outer panel 23 , and the eighth arc transition plate 29 can improve the connection strength between the fifth outer panel 27 and the third outer panel 23 , and can reduce stress concentration at the connection between the fifth outer panel 27 and the third outer panel 23 .
[0061] Combination Figure 3As shown, the radius of the circle corresponding to the fifth arc transition plate 18, the sixth arc transition plate 19, the seventh arc transition plate 28 and the eighth arc transition plate 29 is R, and R satisfies the relationship: 8mm<R<12mm.
[0062] Specifically, if the radius of the circle corresponding to the fifth arc transition plate 18, the sixth arc transition plate 19, the seventh arc transition plate 28 and the eighth arc transition plate 29 in the utility model is set to not exceed 8 mm, the fifth arc transition plate 18, the sixth arc transition plate 19, the seventh arc transition plate 28 and the eighth arc transition plate 29 are prone to stress concentration. In order to ensure the structural strength of the fifth arc transition plate 18, the sixth arc transition plate 19, the seventh arc transition plate 28 and the eighth arc transition plate 29, it is necessary to set the radius of the circle corresponding to the fifth arc transition plate 18, the sixth arc transition plate 19, the seventh arc transition plate 28 and the eighth arc transition plate 29 to be greater than 8 mm.
[0063] If the radius of the circle corresponding to the fifth arc transition plate 18, the sixth arc transition plate 19, the seventh arc transition plate 28 and the eighth arc transition plate 29 in the utility model is set to be not less than 12 mm, the structural strength of the fifth arc transition plate 18, the sixth arc transition plate 19, the seventh arc transition plate 28 and the eighth arc transition plate 29 will be low and easy to break. In order to ensure the structural reliability of the fifth arc transition plate 18, the sixth arc transition plate 19, the seventh arc transition plate 28 and the eighth arc transition plate 29, it is necessary to set the radius of the circle corresponding to the fifth arc transition plate 18, the sixth arc transition plate 19, the seventh arc transition plate 28 and the eighth arc transition plate 29 to be less than 12 mm.
[0064] In the embodiment of the utility model, the radius of the circle corresponding to the fifth arc transition plate 18, the sixth arc transition plate 19, the seventh arc transition plate 28 and the eighth arc transition plate 29 is set to R, and R satisfies the relationship: 10mm≤R<12mm.
[0065] Combination Figure 2 As shown, the thickness of the side beam outer plate 20 is D, and D satisfies the relationship: 0.7mm<D<0.9mm. Specifically, in the embodiment of the utility model, the front wheel cover side beam assembly 100 is a double "X"-shaped structure composed of the side beam inner plate 10 and the side beam outer plate 20. The "X"-shaped structure has high torsional rigidity and bending rigidity. With such a configuration, compared with the prior art, the embodiment of the utility model can reduce the thickness of the side beam outer plate 20 while improving the strength performance of the front wheel cover side beam assembly 100.
[0066] Furthermore, the thickness of the side beam outer plate 20 in the present invention is set between 0.7 mm and 0.9 mm. If the thickness of the side beam outer plate 20 is set to be less than 0.7 mm, the rigidity of the side beam outer plate 20 will be affected, and the strength performance of the front wheel housing side beam assembly 100 will be reduced. In this way, the thickness of the side beam outer plate 20 in the present invention is greater than 0.7 mm.
[0067] Furthermore, if the thickness of the side beam outer plate 20 is set to exceed 0.9 mm, the side beam outer plate 20 will still have the problem of too thick sheet material and being unfavorable for forming, which is even more unfavorable for product cost reduction and efficiency improvement. Therefore, the thickness of the side beam outer plate 20 in the utility model is less than 0.7 mm.
[0068] According to an embodiment of the utility model, the vehicle includes the front wheel cover side beam assembly 100 in the embodiment of the utility model. The front wheel cover side beam assembly 100 of the utility model is a double-X-shaped all-inclusive structure composed of a side beam inner plate 10 and a side beam outer plate 20, which is used to overlap with the wheel cover to play an important role in carrying front-end components and transmitting collision force and absorbing energy in the front engine room of the vehicle. The front wheel cover side beam assembly 100 of the utility model has better strength performance and reduced sheet material thickness, which can reduce development costs and has a dual optimization effect of reducing costs and increasing efficiency.
