[0061] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0062] According to the first aspect of the present application, with reference to Figures 1 to 4 , the present application provides a shock tower 100, including: a body 110 and a first type of mounting part 120.

[0063] The body 110 has a connecting part 111 for connecting a shock absorber, and the first type of mounting part 120 is used for connecting a swing arm. The first type of mounting part 120 and the body 110 are integrally formed.

[0064] It can be understood that the first type of mounting part 120 is movably connected to the swing arm, and the specific movable connection manner can be bolt connection, spring pin connection or ball head connection, etc.

[0065] Exemplarily, the first type of mounting portion 120 and the body 110 are integrally cast, and specifically, an aluminum casting structure can be adopted.

[0066] Through the above technical solution, by integrally forming the first type of mounting portion 120 for connecting the swing arm and the body 110, the connection points between structural members are reduced, the overall strength and stability of the structure are enhanced, the assembly complexity can be reduced, and the torsional resistance and rigidity of the vehicle frame are improved.

[0067] Meanwhile, by integrally forming the first type of mounting portion 120 and the body 110, additional connecting parts 111 and welding can be reduced, thereby reducing the weight of the shock tower 100 and the vehicle frame and improving the fuel efficiency and power performance of the vehicle 10.

[0068] Integrating the first type of mounting portion 120 and the body 110 into one body makes full use of space, simplifies the vehicle frame structure, makes the vehicle frame structure more compact, and improves the flexibility of the layout of the vehicle 10.

[0069] In some embodiments, referring to Figures 1 to 4 , the shock tower 100 further includes: a second type of mounting portion 130.

[0070] The second type of mounting portion 130 is used to mount a reinforcing cross beam, and the reinforcing cross beam is connected between two shock towers 100 located on the left and right sides of the vehicle 10 to resist the lateral torsion and impact loads received by the shock tower 100. In the first direction Z, the second type of mounting portion 130 is located on one side of the first type of mounting portion 120 to facilitate the connection between the shock tower 100, the swing arm, and the reinforcing cross beam.

[0071] Here, the first direction Z indicating the up and down direction is only for the convenience of introducing the specific embodiments of the present application, and there is no absolute corresponding relationship between the first direction Z and the up and down direction. Similarly, there is no absolute corresponding relationship between the second direction X and the left and right direction, and the third direction Y and the front and back direction. Moreover, the first direction Z, the second direction X, and the third direction Y of the present application are only for expressing relative positional relationships, and they only indicate the general orientation, rather than an absolute geometric relationship.

[0072] Exemplarily, the second type of mounting portion 130 is located at the top of the shock tower 100, and in the third direction Y (front and back direction), at least a part of the second type of mounting portion 130 is located between the connecting portion 111 and the first type of mounting portion 120.

[0073] In some embodiments, the second type of mounting portion 130 and the body 110 are integrally formed.

[0074] Exemplarily, the second type of mounting portion 130 and the body 110 are integrally cast, and specifically, an aluminum casting structure can be adopted.

[0075] With the above solution, the body 110, the first type of mounting portion 120, and the second type of mounting portion 130 of the shock absorber tower 100 are combined into a whole, and are connected to the vehicle frame by means of integral casting and machining. The integrally cast combined shock absorber tower 100 can reduce the number of parts, reduce the part assembly steps, enhance the overall strength, and is beneficial to realizing the integrated, high-strength, and lightweight design of the vehicle 10.

[0076] In some embodiments, referring to Figures 1 to 3 , the second type of mounting portion 130 further forms a frame opening 130a, and the frame opening 130a is open.

[0077] Exemplarily, the opening direction of the frame opening 130a is arranged at an angle with the third direction Y, providing a larger operating space for the assembly of the second type of mounting portion 130 and the reinforcing cross beam.

[0078] With such a solution, through the design of the frame opening 130a, the structural stiffness and strength of the second type of mounting portion 130 can be effectively increased, and the load distribution can be optimized.

[0079] In some embodiments, referring to Figure 1 and Figure 2 , the second type of mounting portion 130 has: side plates 131 and a top plate 132.

[0080] Two side plates 131 are respectively formed with first fixing holes 131a, and in the second direction X perpendicular to the first direction Z, the two side plates 131 are spaced apart. Exemplarily, the first fixing holes 131a penetrate through the side plates 131 along the second direction X (left and right direction), and the first fixing holes 131a are used for bolt connection between the second type of mounting portion 130 and the reinforcing cross beam.

[0081] The top plate 132 is located between the two side plates 131 and is respectively connected to the two side plates 131. The frame opening 130a is at least surrounded by the top plate 132, the body 110, and the side plates 131.

[0082] In some embodiments, referring to Figure 2 , the thickness of at least part of the side plates 131 is greater than the thickness of the top plate 132. With such a setting, the strength and rigidity of the side plates 131 can be improved, making the connection between it and the reinforcing cross beam more firm and reliable.

[0083] In some embodiments, referring to Figure 4 , the shock absorber tower 100 includes at least two first type of mounting portions 120, and a connecting portion 111 is located between the two first type of mounting portions 120.

[0084] With such an arrangement, by providing two first - type mounting parts 120, the acting force of the suspension system is dispersed to multiple parts of the shock tower 100, reducing the load on a single swing arm and improving the durability and reliability of the shock tower 100.

[0085] In some embodiments, referring to Figure 5 , inside the body 110, there is also: a reinforcing rib 112.

[0086] There are multiple reinforcing ribs 112, and the multiple reinforcing ribs 112 divide the interior structure of the body 110 into multiple hollow areas 110a; the hollow areas 110a are open in the second direction X (left - right direction).

[0087] Exemplarily, the shape of the hollow area 110a can be one or a combination of a triangle, a trapezoid, or an irregular polygon. Each hollow area 110a is independent of each other.

[0088] With such a solution, the weight of the shock tower 100 casting is reduced. While meeting the requirements of multiple types of mounting parts, the structural strength is ensured and the structural stability is improved.

[0089] In some embodiments, referring to Figure 5 , the extending directions of the multiple reinforcing ribs 112 intersect at a central area 140.

[0090] Exemplarily, adjacent reinforcing ribs 112 are inclined to each other, and the position where the multiple reinforcing ribs 112 intersect forms a central area 140.

[0091] With such a solution, a support structure is formed inside the shock tower 100. When the shock tower 100 is subjected to stress in any direction, after being transmitted to the central area 140, it can be dispersed along the multiple reinforcing ribs 112, effectively dispersing and bearing the external load, thereby improving the overall strength and rigidity of the shock tower 100.

[0092] In some embodiments, referring to Figure 5 , a first opening 141 is provided in the central area 140 of several reinforcing ribs 112. With such a setting, the occurrence of stress concentration in the central area 140 is further reduced.

[0093] Exemplarily, the first opening 141 extends along the second direction X (left - right direction).

[0094] In some embodiments, referring to Figure 5 , a second opening 112a is provided at one end of the reinforcing rib 112 away from the central area 140. With such a setting, the occurrence of stress concentration at the connection between the reinforcing rib 112 and the body 110 is further reduced.

[0095] Exemplarily, the second opening 112a is arranged to extend along the second direction X (left - right direction).

[0096] In some embodiments, referring to Figure 1 and Figure 3 , the connecting portion 111 has: a second fixing hole 111a.

[0097] A plurality of second fixing holes 111a are provided for fixing the shock absorber; wherein, the plurality of second fixing holes 111a are arranged at intervals around a central axis C1.

[0098] Exemplarily, three second fixing holes 111a are provided, and the three second fixing holes 111a are evenly spaced around the central axis C1 for bolt connection with the shock absorber.

[0099] Adopting such an arrangement of the second fixing holes 111a can enhance the anti - roll ability of the connecting portion 111, is beneficial to dispersing the load, and improves the connection strength.

[0100] In some embodiments, referring to Figure 1 and Figure 3 , the connecting portion 111 further has: a mounting hole 110b.

[0101] The mounting hole 110b axially penetrates the connecting portion 111 along the central axis C1 for at least part of the shock absorber to pass through; wherein, the plurality of second fixing holes 111a are arranged at intervals in the circumferential direction of the mounting hole 110b, that is, the hole wall of the mounting hole 110b is also arranged around the central axis C1.

[0102] Adopting such a scheme, through the setting of the mounting hole 110b, it is convenient to position the shock absorber with the connecting portion 111. At the same time, by setting the second fixing holes 111a based on the mounting hole 110b, it is convenient to position the mounting hole 110b.

[0103] According to the second aspect of the present application, referring to Figure 6 , a vehicle 10 is provided, and the vehicle 10 includes the above - mentioned shock tower 100. The vehicle 10 has all the beneficial effects of the above - mentioned shock tower 100, and details are not described herein again.

[0104] The vehicle 10 further includes: a longitudinal beam. The shock tower 100 is arranged on the longitudinal beam, so that the shock tower 100 can absorb, buffer and transmit the impact from the outside to the longitudinal beam, protecting other structures inside the vehicle frame.

[0105] As an alternative scheme, the shock tower 100 and the longitudinal beam are integrally formed, which can further reduce the assembly steps, enhance the overall strength, and is beneficial to realizing the integration of the vehicle 10.

[0106] Exemplarily, the shock absorber tower 100 and the longitudinal beam are integrally cast, and a cast aluminum structure can be specifically adopted.

[0107] The vehicle 10 can be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and the present application does not make specific limitations thereto.
