[0036] The following is for reference. Figures 1-6 The upper swing arm structure 100 according to the embodiment of the present utility model is simple in structure, can improve the structural strength of the upper swing arm structure 100, improve the force transmission effect, and thus improve the reliability of the upper swing arm structure 100, thereby improving vehicle stability and driving safety.

[0037] like Figures 1-6 As shown, the upper swing arm structure 100 according to one embodiment of the present utility model includes: two sub-swing arms 1.

[0038] Two sub-arms 1 are connected at one end and spaced apart at the other end to define a cavity 4. A ball pin mounting part 2 is provided at the connection of the two sub-arms 1, and a bushing mounting part 3 is provided at the other end of each sub-arm 1. Each sub-arm 1 has an inner boss area 11 near the cavity 4. The width of the inner boss area 11 is set to gradually increase from the bushing mounting part 3 to the ball pin mounting part 2, and / or the height of the inner boss area 11 is set to gradually decrease from the bushing mounting part 3 to the ball pin mounting part 2.

[0039] The vehicle is equipped with a suspension system, which is a support system composed of springs and shock absorbers between the vehicle body and the tires. The suspension system can support the vehicle body and improve the ride comfort. The suspension system can be equipped with an upper control arm structure 100 and a lower control arm structure. The upper control arm structure 100 can guide and support the suspension, while the lower control arm structure can support the vehicle body and shock absorbers and other structures, and can buffer vibrations during driving, thereby ensuring the vehicle's driving stability.

[0040] Specifically, the upper swing arm structure 100 is provided with two sub-swing arms 1. The two sub-swing arms 1 can be configured as straight swing arms or arc swing arms, etc., and can be configured as the same or different according to actual needs. The configuration method is flexible. One end of the two sub-swing arms 1 can be connected by welding or integral molding, etc., and the other end of the two sub-swing arms 1 is spaced apart so that a cavity 4 can be defined between the two sub-swing arms 1. According to the configuration shape of the sub-swing arms 1, the cavity 4 can be constructed as a semi-circular cavity or a triangular cavity, etc. The cavity 4 can avoid other structures in the suspension system to ensure the reliability of the suspension system operation.

[0041] Furthermore, a ball joint mounting part 2 is provided at the connection point of the two sub-swing arms 1. The ball joint mounting part 2 is used to install the ball joint pin. The upper swing arm structure 100 can be connected to other structures through the ball joint pin to realize the up-and-down movement and steering movement of the wheel, ensuring the stability of vehicle operation. The other end of each of the two sub-swing arms 1 is provided with a bushing mounting part 3. The bushing mounting part 3 is used to install the bushing. When the vehicle is driving, the vehicle's suspension system will also shake and vibrate. The bushing can prevent the mutual movement interference between the components of the suspension system during the shaking and vibration process, and can also prevent the suspension system from being subjected to external impacts and vibrations, thereby improving the driving comfort of the vehicle.

[0042] Furthermore, each sub-swing arm 1 is provided with an inner boss area 11. The inner boss area 11 is located in the part of the sub-swing arm 1 near the cavity 4. The width of the inner boss area 11 is set to gradually increase from the bushing mounting part 3 to the ball pin mounting part 2, and / or the height of the inner boss area 11 is set to gradually decrease from the bushing mounting part 3 to the ball pin mounting part 2. Alternatively, the width of the inner boss area 11 can be set to gradually increase from the bushing mounting part 3 to the ball pin mounting part 2, or the height of the inner boss area 11 can be set to gradually decrease from the bushing mounting part 3 to the ball pin mounting part 2, or the width of the inner boss area 11 can be set to gradually increase from the bushing mounting part 3 to the ball pin mounting part 2, and the height of the inner boss area 11 can be set to gradually decrease from the bushing mounting part 3 to the ball pin mounting part 2.

[0043] In this embodiment, the width of the inner boss region 11 is set to gradually increase from the bushing mounting portion 3 to the ball pin mounting portion 2, and the height of the inner boss region 11 is set to gradually decrease from the bushing mounting portion 3 to the ball pin mounting portion 2. The width of the inner boss region 11 is set to gradually increase from the bushing mounting portion 3 to the ball pin mounting portion 2, that is, the width of the inner boss region 11 at the bushing mounting portion 3 is set to be the minimum, and the width at the ball pin mounting portion 2 is set to be the maximum, so as to improve the structural strength of the ball pin mounting portion 2 and the two sub-swing arms 1 in the horizontal direction. The height of the inner boss region 11 is set to gradually decrease from the bushing mounting portion 3 to the ball pin mounting portion 2, that is, the height of the inner boss region 11 at the bushing mounting portion 3 is set to be the maximum, and the height at the ball pin mounting portion 2 is set to be the minimum, so as to improve the structural strength of the bushing mounting portion 3 and the two sub-swing arms 1 in the vertical direction.

[0044] Therefore, the structural strength of the upper swing arm structure 100 in all directions can be improved by the inner boss area 11, and the inner boss area 11 can increase the force transmission path of the sub-swing arm 1, thereby improving the force transmission effect and thus improving the reliability of the upper swing arm structure 100, thereby improving vehicle stability and driving safety.

[0045] According to an embodiment of the present invention, the upper control arm structure 100 has a ball pin mounting part 2 at the connection of the two sub-control arms 1, and a bushing mounting part 3 at the other end of each of the two sub-control arms 1. The structure is simple and can ensure the installation reliability of the upper control arm structure 100. Each sub-control arm 1 has an inner boss area 11 near the cavity 4. The width of the inner boss area 11 is set to gradually increase from the bushing mounting part 3 to the ball pin mounting part 2, and the height of the inner boss area 11 is set to gradually decrease from the bushing mounting part 3 to the ball pin mounting part 2. In this way, the overall structural strength of the upper control arm structure 100 can be improved by the inner boss area 11, and the force transmission path can be increased to improve the force transmission effect. This can improve the reliability of the upper control arm structure 100, improve vehicle stability and driving safety, and have better performance and wider applicability.

[0046] In some embodiments, each sub-swing arm 1 has an outer boss region 12 formed on the portion away from the cavity 4. The outer boss region 12 is located outside the inner boss region 11, and the width of the outer boss region 12 is set to gradually decrease from the bushing mounting portion 3 to the ball pin mounting portion 2.

[0047] Specifically, each sub-swing arm 1 is provided with an outer boss area 12, such as Figures 1-4 As shown, the outer boss area 12 is located on the part of the sub-swing arm 1 away from the cavity 4, that is, the outer boss area 12 is located outside the inner boss area 11, so that each sub-swing arm 1 has an inner boss area 11 on its inner side and an outer boss area 12 on its outer side, thereby improving the structural strength of the inner and outer sides of each sub-swing arm 1, thereby improving the overall structural strength of the upper swing arm structure 100. When the upper swing arm structure 100 is subjected to force, the force can be transmitted through the sub-swing arm 1, the outer boss area 12 and the inner boss area 11 respectively, which can disperse the force and weaken the effect of the force, thereby improving the reliability of the upper swing arm structure 100.

[0048] Furthermore, the width of the outer boss area 12 is set to gradually decrease from the bushing mounting part 3 to the ball pin mounting part 2, that is, the width of the outer boss area 12 is set to be the largest at the bushing mounting part 3 and the smallest at the ball pin mounting part 2. The width of the inner boss area 11 is set to be the smallest at the bushing mounting part 3 and the largest at the ball pin mounting part 2. That is, the inner boss area 11 can improve the structural strength of the bushing mounting part 3, and can reduce the weight of the outer boss area 12 while ensuring the structural strength of the ball pin mounting part 2, so as to improve lightweighting and ensure the reliability of the upper swing arm structure 100.

[0049] In some embodiments, a groove region 13 is formed at the connection between the inner boss region 11 and the outer boss region 12 of each sub-swing arm 1.

[0050] Specifically, each sub-swing arm 1 has an inner boss area 11 on its inner side and an outer boss area 12 on its outer side, and as shown... Figures 1-2 As shown, a recessed groove area 13 is provided between the inner boss area 11 and the outer boss area 12 of each sub-swing arm 1. The recessed groove area 13 can extend from the ball pin mounting part 2 to the bushing mounting part 3. The extension length of the recessed groove area 13 can be set to be equal to the length of the sub-swing arm 1, or it can be set to be equal to the length of the sub-swing arm 1. It can be adjusted according to the actual situation to improve the flexibility of the setting.

[0051] Furthermore, the recessed area 13 can be recessed vertically into the interior of the sub-swing arm 1, making the thickness of the middle area of ​​the sub-swing arm 1 thinner, thereby reducing the manufacturing materials required for the sub-swing arm 1, thus reducing manufacturing costs and the weight of the sub-swing arm 1. By setting the recessed area 13 in each sub-swing arm 1, the overall lightweight of the upper swing arm structure 100 can be improved, thereby extending the vehicle's range performance.

[0052] In addition, the height of the inner boss area 11 is set to be higher than the height of the outer boss area 12, so that the height of the upper swing arm structure 100 along the distribution direction of the two sub-swing arms 1 forms a low-high-low trend, and the width of the inner boss area 11 near the ball pin mounting part 2 gradually increases, so that the inner boss area 11 can form a triangular area, thereby improving the overall structural strength and torsional resistance of the upper swing arm structure 100, and improving the reliability of the upper swing arm structure 100.

[0053] In some embodiments, each sub-arm 1 has at least one first weight reduction hole 131 in its sinking area 13.

[0054] Specifically, each sub-swing arm 1 has a recessed area 13 extending along the length of the sub-swing arm 1 in its middle, in order to improve the weight reduction of the sub-swing arm 1, and as... Figures 1-2 As shown, each sub-swing arm 1 is also provided with at least one first weight reduction hole 131, that is, the first weight reduction hole 131 can be provided one, two or three, etc. At least one first weight reduction hole 131 is provided in the sink area 13. The first weight reduction hole 131 can be a circular hole or an elongated hole, etc. Providing at least one first weight reduction hole 131 in the sink area 13 can reduce the material required for the sub-swing arm 1 as a whole, thereby reducing the manufacturing cost. Furthermore, providing at least one first weight reduction hole 131 in the sink area 13 can reduce the weight of each sub-swing arm 1, thereby improving the overall lightweight of the upper swing arm structure 100.

[0055] In addition, by setting the first weight reduction hole 131 in the sink groove area 13, the integrity of the inner boss area 11 and the outer boss area 12 can be guaranteed, so as to ensure the structural strength of the inner boss area 11 and the outer boss area 12. This can improve the weight reduction while ensuring the structural strength of the upper swing arm structure 100, so as to ensure the reliability of the upper swing arm structure 100.

[0056] In some embodiments, there are multiple first weight reduction holes 131, and the multiple first weight reduction holes 131 are distributed sequentially at intervals from the bushing mounting portion 3 to the ball pin mounting portion 2.

[0057] Specifically, the settling tank area 13 is provided with first weight-reducing holes 131, and there are multiple first weight-reducing holes 131, that is, the first weight-reducing holes 131 can be two, three, or four, etc. In this embodiment, for example... Figures 1-2 As shown, there are three first weight reduction holes 131. Multiple first weight reduction holes 131 can be distributed sequentially from bushing mounting part 3 to ball pin mounting part 2. Setting multiple first weight reduction holes 131 can reduce the manufacturing material of sub-swing arm 1, thereby reducing manufacturing costs. In addition, multiple first weight reduction holes 131 can improve the lightweight of sub-swing arm 1, thereby improving the overall lightweight of upper swing arm structure 100.

[0058] In addition, a connecting area is formed between two adjacent first weight-reducing holes 131, and multiple first weight-reducing holes 131 are spaced apart in the sinking area 13, so that multiple connecting areas are formed in the sinking area 13. The two sides of the connecting area are connected to the inner boss area 11 and the outer boss area 12 respectively. This allows the force to be transmitted through the connecting area to the outer boss area 12 when it is transmitted through the inner boss area 11, and the force to be transmitted through the connecting area to the inner boss area 11 when it is transmitted through the outer boss area 12. This increases the force transmission path and allows the force transmission direction to change multiple times in each sub-swing arm 1, thereby improving the weakening effect of the force and improving the reliability of the upper swing arm structure 100.

[0059] Thus, the upper swing arm structure 100 can adopt a leaf vein-like biomimetic design, with the two inner protrusion areas 11 serving as the "main veins" of the "leaf veins," providing the main support for the upper swing arm structure 100. The multiple connecting areas between the multiple first weight-reducing holes 131 can be regarded as the "branch veins" of the "leaf veins," providing support for the outer protrusion area 12. This improves the strength and rigidity of the two sub-swing arms 1. Furthermore, the leaf vein-like biomimetic design makes the internal structure of the upper swing arm structure 100 stronger, ensuring the reliability of the upper swing arm structure 100. It also allows for the rational allocation of materials, maximizing material utilization and improving the lightweight effect.

[0060] In some embodiments, the two sub-swing arms 1 are distributed along the front-rear direction of the vehicle, and the length of the sinking area 13 of the sub-swing arm 1 located on the front side is less than the length of the sinking area 13 of the sub-swing arm 1 located on the rear side.

[0061] Specifically, the upper control arm structure 100 is installed in the vehicle's suspension system and can control the wheels to steer, etc. When the upper control arm structure 100 is installed in the vehicle, the two sub-control arms 1 of the upper control arm structure 100 can be distributed along the front-rear direction of the vehicle, that is, one of the two sub-control arms 1 is located in front of the other, and the length of the groove area 13 of the sub-control arm 1 located in front is set to be less than the length of the groove area 13 of the sub-control arm 1 located in rear, that is, the length of the groove area 13 of the sub-control arm 1 located in front is set to be shorter, and the length of the groove area 13 of the sub-control arm 1 located in rear is set to be longer.

[0062] Furthermore, setting a groove area 13 in the sub-swing arm 1 can improve the weight reduction of the sub-swing arm 1. When the upper swing arm structure 100 is installed in the vehicle, the front sub-swing arm 1 is located close to the front end of the vehicle, which makes the front sub-swing arm 1 subject to a larger positive impact force and the rear sub-swing arm 1 subject to a smaller positive impact force. Thus, by setting the length of the groove area 13 of the front sub-swing arm 1 to be smaller than the length of the groove area 13 of the rear sub-swing arm 1, the structural strength of the front sub-swing arm 1 can be higher than that of the rear sub-swing arm 1, thereby improving the reliability of the front sub-swing arm 1 in resisting positive impacts and improving the safety of the upper swing arm structure 100 in use.

[0063] In some embodiments, the outer boss areas 12 of the two sub-swing arms 1 extend to both sides of the ball pin mounting portion 2.

[0064] Specifically, each sub-swing arm 1 has an outer boss area 12 on its outer side, and the outer boss area 12 extends along the length direction of the sub-swing arm 1, and as shown in the figure. Figures 1-4 As shown, the two outer boss areas 12 can extend to both sides of the ball pin mounting part 2 to enhance the structural strength of both sides of the ball pin mounting part 2. The force on the ball pin mounting part 2 can be transmitted through the two outer boss areas 12. This can improve the structural strength of the upper swing arm structure 100 while weakening the effect of the force, thereby improving the reliability of the upper swing arm structure 100.

[0065] In addition, such as Figures 5-6 As shown, the cross-sectional structure of the main body and inner boss area 11 of the sub-swing arm 1 at the connection with the bushing mounting part 3 is "L" shaped, which can distribute the force to the main body and inner boss area 11 of the sub-swing arm 1, thereby dispersing the force and improving the reliability of the upper swing arm structure 100.

[0066] In other embodiments, the inner boss areas 11 of the two sub-arms 1 extend to meet each other and are both connected to the ball pin mounting portion 2.

[0067] Specifically, each sub-swing arm 1 has an inner boss area 11 on its inner side, and the inner boss area 11 extends along the length direction of the sub-swing arm 1, and as shown in the figure. Figures 1-4 As shown, the inner boss areas 11 of the two sub-swing arms 1 extend to connect with each other, thereby forming a complete inner boss area 11 on the inner side of the upper swing arm structure 100. The connection between the two inner boss areas 11 is connected to the ball pin mounting part 2, which can enhance the structural strength of the ball pin mounting part 2. The force on the ball pin mounting part 2 can be transmitted through the inner boss area 11. Thus, while improving the structural strength of the upper swing arm structure 100, the effect of the force can also be weakened, thereby improving the reliability of the upper swing arm structure 100.

[0068] In some embodiments, a second weight-reducing hole 14 is formed at the junction of the inner boss regions 11 of the two sub-swing arms 1.

[0069] Specifically, one end of the two sub-swing arms 1 is connected, and each sub-swing arm 1 has an inner boss area 11 on its inner side. That is, one end of the two inner boss areas 11 can also extend to the ball pin mounting part 2 and connect there. The width of the inner boss area 11 is set to gradually increase from the bushing mounting part 3 to the ball pin mounting part 2, that is, the width of the inner boss area 11 is the largest at the ball pin mounting part 2. Figures 1-2 As shown, a second weight reduction hole 14 is formed at the junction of the inner boss area 11 of the two sub-swing arms 1. That is, a second weight reduction hole 14 is provided at the maximum width of the two sub-swing arms 1. This can improve the structural strength around the ball pin mounting part 2 while reducing the overall weight of the upper swing arm structure 100, thereby improving lightweighting and extending the vehicle's range.

[0070] In some embodiments, the upper swing arm structure 100 is made of aluminum alloy.

[0071] Specifically, the upper control arm structure 100 can be made of aluminum alloy. Aluminum alloy is an alloy based on aluminum with the addition of a certain amount of other alloying elements. Aluminum alloy is a light metal material. In addition to the general properties of aluminum, aluminum alloy also has some specific alloy properties depending on the type and amount of alloying elements added. Aluminum alloy has high strength and rigidity, good casting performance, plastic processing performance, electrical conductivity, thermal conductivity, as well as good corrosion resistance and weldability. This can improve the reliability of the upper control arm structure 100. In addition, the light weight of aluminum alloy can also improve the lightweight of the upper control arm structure 100, thereby improving the vehicle's range performance and thus improving the user experience.

[0072] In other embodiments, the upper swing arm structure 100 is integrally formed by forging.

[0073] Specifically, the upper swing arm structure 100 can be integrally formed by forging. Forging is a processing method that uses forging machinery to apply pressure to a metal billet, causing it to undergo plastic deformation to obtain a forging with certain mechanical properties, shape, and size. Integral forming means that the entire part is formed in one mold at a time. The forming process is simple and has the characteristics of low cost and high product quality. Therefore, by adopting integral forging for the upper swing arm structure 100, weld points and other issues can be avoided in the upper swing arm structure 100, thus avoiding stress concentration and improving the structural strength of the upper swing arm structure 100. This ensures the reliability of the upper swing arm structure 100 in use, and also reduces manufacturing costs and improves production efficiency.

[0074] In other embodiments, the sub-swing arm 1 is constructed as an arc shape, and the tangent at one end of the sub-swing arm 1 is perpendicular to the tangent at the other end.

[0075] Specifically, the upper swing arm structure 100 is provided with two sub-swing arms 1, and both sub-swing arms 1 are constructed as arc-shaped structures. The dots of the two arc-shaped structures are set towards each other. By making the sub-swing arms 1 as arc-shaped structures, the cavity 4 is also an arc-shaped area, which can increase the area of ​​the cavity 4, thereby improving the avoidance effect of the upper swing arm structure 100 on other structures, reducing the risk of interference, ensuring operational reliability, and dispersing stress. While ensuring strength, it reduces the amount of material used and improves lightweighting.

[0076] In addition, when the upper control arm structure 100 is installed in the vehicle, constructing the sub-control arm 1 as an arc-shaped structure can improve the dispersion effect of the sub-control arm 1 on the impact force, improve fatigue life, and optimize the stiffness of the sub-control arm 1 by adjusting the curvature to balance the handling and comfort of the upper control arm structure 100. At the same time, the arc-shaped structure can absorb high-frequency vibrations through its own deformation, thereby reducing the noise transmitted to the vehicle body through the upper control arm structure 100 and improving the comfort of use.

[0077] Furthermore, the tangent at one end of the sub-swing arm 1 is set to be perpendicular to the tangent at the other end, so that when the force is transmitted through the sub-swing arm 1, the direction of force transmission changes, making the direction of force transmission to the sub-swing arm 1 perpendicular to the direction of force transmission out of the sub-swing arm 1, thereby weakening the effect of the force and ensuring the reliability of the upper swing arm structure 100.

[0078] This utility model also proposes a vehicle.

[0079] The vehicle according to the present invention includes the upper control arm structure 100 of any of the above claims.

[0080] According to the vehicle of this utility model embodiment, an upper control arm structure 100 is provided, and a ball pin mounting part 2 is provided at the connection of the two sub-control arms 1 of the upper control arm structure 100. The other end of each of the two sub-control arms 1 is provided with a bushing mounting part 3. The structure is simple and can ensure the installation reliability of the upper control arm structure 100. Each sub-control arm 1 has an inner boss area 11 near the cavity 4. The width of the inner boss area 11 is set to gradually increase from the bushing mounting part 3 to the ball pin mounting part 2, and the height of the inner boss area 11 is set to gradually decrease from the bushing mounting part 3 to the ball pin mounting part 2. In this way, the overall structural strength of the upper control arm structure 100 can be improved by the inner boss area 11, and the force transmission path can be increased to improve the force transmission effect. This can improve the reliability of the upper control arm structure 100, improve vehicle stability and driving safety, and have better performance and wider applicability.
