[0053] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0054] refer to Figures 1 to 15 As shown, the present application provides a vehicle frame 100, which can be used to form a part of the vehicle chassis to carry other parts of the vehicle, such as but not limited to: powertrain, suspension, and mounting, and of course other parts of the vehicle can also be installed.

[0055] The vehicle frame 100 can be used as a main vehicle frame, or as a front sub-frame or a rear sub-frame. The specific application can be selected according to the actual situation, which will not be described in detail here.

[0056] For the convenience of introduction, the directions of up, down, left, right, front and back are used in the corresponding drawings to facilitate the introduction of the relative position relationship between the various parts in this application, which should not be understood as a limitation on the absolute position. In addition, the height and level in this application are only used to illustrate the technical features relative to the position of the frame in normal use. As mentioned above, the directions of this application are only for the purpose of introducing the relative position and direction relationship, not the absolute direction. Therefore, the concepts of up, down, left, right, front and back, height, level, etc. should be considered to constitute a limitation on the relative position relationship of this application.

[0057] The first direction, the second direction and the third direction of the present application are only for expressing relative positional relationships. They only indicate approximate directions rather than absolute geometric relationships.

[0058] refer to Figures 1 to 4 As shown, the vehicle frame 100 includes a body 110 and a plurality of mounting structures 120 .

[0059] The main body 110 includes a cross beam 111 and a longitudinal beam 112 .

[0060] refer to Figure 1 and Figure 2 As shown, the cross beam 111 includes a first cross beam 111 a and a second cross beam 111 b , and the longitudinal beam 112 includes a first longitudinal beam 112 a and a second longitudinal beam 112 b .

[0061] The first cross beam 111a is fixedly connected to the first longitudinal beam 112a and the second longitudinal beam 112b by welding or other fixing methods, so that the first cross beam 111a is located between the first longitudinal beam 112a and the second longitudinal beam 112b in the left-right direction.

[0062] The second cross beam 111b is arranged at intervals on the rear side of the first cross beam 111a, and the rear ends of the first longitudinal beam 112a and the second longitudinal beam 112b are fixedly connected to the second cross beam 111b. The first cross beam 111a, the first longitudinal beam 112a, the second cross beam 111b and the second longitudinal beam 112b are connected to form a frame structure, and form an inter-beam space 110a surrounded by the frame structure.

[0063] refer to Figures 1 to 4 As shown, a plurality of mounting structures 120 are provided on the vehicle frame 100 . Each mounting structure 120 can be provided on the cross beam 111 or the longitudinal beam 112 according to the specific vehicle model and requirements. The mounting structure 120 is fixedly connected to the cross beam 111 and the longitudinal beam 112 .

[0064] In some specific embodiments, the plurality of mounting structures 120 may be fixed to the cross beam 111 and the longitudinal beam 112 by welding.

[0065] The mounting structure 120 is used to mount at least one of a suspension (a suspension assembly or a part thereof), a suspension (a suspension assembly or a part thereof), and a vehicle body (a vehicle body assembly or a part thereof).

[0066] The mounting structure 120 has a mounting reference 120a for determining the relative position of at least one of the mounting, the vehicle body or the suspension and the mounting structure 120. The mounting reference 120a can be a plane and / or axis defined by the edge of the end face of the mounting structure, or a plane and / or a straight line defined by a space such as a hole or a slot of the mounting structure; these planes and / or straight lines can determine the position of the mounting, the suspension and the vehicle body relative to the vehicle frame when the vehicle frame is assembled with the mounting, the suspension and the vehicle body.

[0067] refer to Figures 1 to 4 As shown, in the present application, the maximum distance between two adjacent mounting bases 120a for mounting the vehicle body in the horizontal direction can be defined as the base span X (or Y). The ratio of the height difference H between the two mounting bases 120a to the base span X (or Y) is less than or equal to 0.14.

[0068] There are multiple mounting structures 120 in the vehicle frame 100, and one mounting structure 120 has multiple mounting references 120a. The height difference H between two mounting references 120a referred to here can be the height difference between any two mounting references 120a. As a more specific solution, the ratio of the height difference H between the two mounting references 120a to the reference span X (or Y) can be less than or equal to 0.139, for example.

[0069] The height difference H between the two mounting references 120a determines the concentration of the load that the mounting structure may be subjected to in the height direction. When the height difference H is smaller, the force arm applied by the load in the height direction is more limited. Under similar materials, the height difference H has a decisive influence on the comprehensive load state of the frame. When the ratio of the height difference H to the reference span is less than or equal to 0.14, the entire frame is flatter and can withstand higher loads without being damaged, avoiding defects such as cracks, and thus the structural strength of the frame 100 can still meet the use requirements under long-term use.

[0070] In some embodiments, the ratio of the height difference between two different installation references 120 a in the frame 100 to the reference span is less than or equal to 0.12, so that the two installation structures 120 are more concentrated in the height direction of the body.

[0071] In some embodiments, the height difference H between two different mounting datums 120a in the frame 100 is less than or equal to 125 mm. By limiting the specific value of the height difference between the two mounting datums 120a, the parts of the frame 100 where the powertrain, suspension, body and other components are assembled are relatively concentrated in the height direction of the frame, thereby limiting the connection positions of these components on the mounting structure 120 and the force arm between the connection positions of the mounting structure 120 and the body 110, which is conducive to improving the structural strength of the frame 100. Further, the height difference H is less than or equal to 123 mm.

[0072] In some embodiments, the maximum distance of the plurality of mounting structures in the height direction is defined as a longitudinal span Z; Figure 3 As shown, the ratio of the height difference H between two different installation references 120a in the frame 100 to the longitudinal span Z is less than or equal to 0.8; further, the ratio of the height difference H between two different installation references 120a in the frame 100 to the longitudinal span Z is less than or equal to 0.78.

[0073] In some embodiments, reference Figure 4As shown, the first cross beam 111a, the first longitudinal beam 112a, the second cross beam 111b and the second longitudinal beam 112b are welded and fixed to each other to form a frame structure. The inter-beam space 110a is located in the area surrounded by the frame structure and penetrates the frame 100 in the height direction of the frame 100.

[0074] The existence of the inter-beam space 110a can reduce the weight of the frame. At the same time, the mounting structure 120 can be arranged inside and outside the inter-beam space 110a, so as to provide sufficient assembly space for the vehicle's powertrain, suspension and other components, and at the same time realize a "flat" frame, it can meet the use requirements of configuring as many components as possible on the frame.

[0075] In some embodiments, the mounting datum 120a of the at least one mounting structure 120 is located outside the inter-beam space 110a in the horizontal direction.

[0076] In some embodiments, the mounting base 120a of the at least one mounting structure 120 is located inside the inter-beam space 110a in the horizontal direction.

[0077] refer to Figures 4 to 14 As shown, in the horizontal direction, the main body 110 may be provided with mounting structures 120 on both the inner and outer sides of the inter-beam space 110 a so as to more centrally assemble other components of the vehicle in the height direction of the frame 100 .

[0078] In some embodiments, the mounting structure 120 includes: a suspension mounting portion 121 and a suspension mounting portion 122. The suspension mounting portion 121 and the suspension mounting portion 122 are used to connect the suspension, which may be a powertrain suspension, and is used to be arranged between the powertrain and the frame 100 to provide a buffer between the frame 100 and the powertrain. The specific structure of the suspension is not described here.

[0079] In some embodiments, a plurality of suspension mounting portions may be provided on the vehicle frame 100, for example, Figure 4 , Figure 7 and Figure 8 The suspension mounting part 121 and the suspension mounting part 122 can be fixed on the body 110 by welding or the like. The suspension mounting part 121 is provided with at least one suspension mounting hole 121a, and the suspension mounting hole 121a is configured to have at least one section of the first rotating body hole wall 121b; the suspension mounting part 122 is provided with at least one suspension mounting hole 122a, and the suspension mounting hole 122a is configured to have at least one section of the first rotating body hole wall 122b.

[0080] The rotation axes of the first rotating body hole wall 121b and the first rotating body hole wall 122b can both serve as the installation reference 120a of the suspension installation portion.

[0081] In some embodiments, reference Figure 4 , Figure 7 and Figure 8 The suspension mounting part 121 and the suspension mounting part 122 are connected to the powertrain suspension through the suspension mounting holes 121a and 122a respectively. The suspension mounting hole 121a can be a cylindrical hole with the first rotation axis L1 as the center line, and the cylindrical inner wall of the suspension mounting hole 121a is the first rotating body hole wall 121b. The suspension mounting hole 122a can be a cylindrical hole with the first rotation axis L2 as the center line, and the cylindrical inner wall of the suspension mounting hole 122a is the first rotating body hole wall 122b.

[0082] A suspension mounting portion 121 is fixedly provided on the first cross beam 111a, and the suspension mounting portion 121 is connected to a powertrain suspension by means of a threaded connection at the suspension mounting hole 121a. A suspension mounting portion 122 is fixedly provided on both the first longitudinal beam 112a and the second longitudinal beam 112b. The suspension mounting portion 122 is connected to a powertrain suspension by means of a threaded connection at the suspension mounting hole 122a.

[0083] refer to Figures 1 to 14 As shown, the first rotation axis L1 of the suspension mounting hole 121a of the suspension mounting portion 121 provided on the first crossbeam 111a is located in the inter-beam space 110a in the horizontal direction and in the height direction of the body. The suspension mounting portion 122 provided on the first longitudinal beam 112a and the second longitudinal beam 112b is located outside the inter-beam space 110a, and is protruded from the upper surface of the first longitudinal beam 112a or the second longitudinal beam 112b in the height direction of the frame. The height positions of the first rotation axis L2 of the suspension mounting holes 122a corresponding to the two suspension mounting portions 122 on the first longitudinal beam 112a and the second longitudinal beam 112b should be consistent, so as to position and install the powertrain suspension. The three suspension mounting portions 121 and 122 are arranged in a triangular distribution on the body 110 to provide stable support for the powertrain.

[0084] The suspension mounting portion 121 is disposed in the middle of the first cross beam 111a and extends at least horizontally toward the interior of the inter-beam space 110a; the suspension mounting portion 122 is disposed at the ends of the first longitudinal beam 112a and the second longitudinal beam 112b and extends at least vertically toward the top of the frame 100; the suspension mounting portions 121 and 122 each include two oppositely disposed suspension mounting brackets.

[0085] In some embodiments, the mounting structure 120 includes a suspension mounting portion 123. The suspension mounting portion 123 is used for active connection to the suspension. The suspension may be, for example, a suspension device connected between the wheel and the vehicle body. Specifically, the suspension mounting portion 123 is actively connected to the swing arm of the suspension device. The specific structure of the suspension is not described in detail here.

[0086] The suspension mounting portion 123 is fixed to the body 110 by welding or other methods. The suspension mounting portion 123 is provided with at least one suspension mounting hole 123a, and the suspension mounting hole 123a is configured to have at least one section of the second rotating body hole wall 123b and at least one section of the plane hole wall 123c. Among the multiple planes where the second rotation axis L3 of the second rotating body hole wall 123b of the suspension mounting hole 123a is located, one plane parallel to the plane hole wall 123c is the installation reference 120a of the suspension mounting portion 123. For example, referring to Figure 4 , Fig. 9 and Fig.10 As shown, the suspension mounting hole 123a is an oval hole, that is, the projection of the hole wall of the suspension mounting hole 123a on the projection plane S1 with the second rotation axis L3 as the normal line is an oval circle, wherein the projection of the second rotating body hole wall 123b is an arc, and the projection of the plane hole wall 123c is a straight line. The swing arm of the suspension device is connected to the suspension mounting part 123 by rotation around the second rotation axis L3 at the oval hole, and can slide relative to the plane hole wall 123c of the suspension mounting hole 123a, so as to connect the suspension to the suspension mounting part 123.

[0087] For vehicles of different models, the form and quantity of suspension are also different, so the number of suspension mounting parts 123 can be set accordingly. Figure 2 and Figure 4 As shown, two suspension mounting parts 123 are respectively provided on the first longitudinal beam 112a and the second longitudinal beam 112b, wherein the two suspension mounting parts 123 on the first longitudinal beam 112a are connected to the swing arm of one suspension, and the two suspension mounting parts 123 on the second longitudinal beam 112b are connected to the swing arm of another suspension, so as to realize the installation of multiple suspensions on the vehicle frame 100. Each suspension mounting part 123 is located outside the inter-beam space 110a in the horizontal direction, so as to connect the suspension to the side of the vehicle frame 100.

[0088] The suspension mounting portion 123 is disposed at the intersection of the cross beam 111 and the longitudinal beam 112 and extends at least in a horizontal direction away from the lateral direction; the suspension mounting portion 123 includes two suspension mounting brackets disposed opposite to each other.

[0089] In some embodiments, the mounting structure 120 includes a vehicle body mounting portion 124. The vehicle body mounting portion 124 is used to fix the vehicle body. The vehicle body can be an assembly of structures such as a chassis and a vehicle body frame. The vehicle body is fixedly connected to the vehicle body mounting portion by threaded connection.

[0090] In some embodiments, the vehicle body mounting portion 124 is fixed to the body 110 by welding or other methods. The vehicle body mounting portion 124 is provided with at least one vehicle body mounting hole 124a, and the vehicle body mounting hole 124a is configured to have at least one third rotating body hole wall 124b. The highest point of the third rotating body hole wall of the vehicle body mounting hole 124a projected on its rotation axis is the mounting reference 120a of the vehicle body mounting portion 124. For example, referring to Figure 4 and Fig.11 As shown, the body mounting hole 124a can be a cylindrical hole with the third rotation axis L4 as the center line, and one end of the body mounting hole 124a along the height direction of the main body passes through the body mounting portion 124, so that when the body and the frame are assembled, the body is fixedly connected to the body mounting portion 124 at the body mounting hole 124a, and the body mounting portion 124 is supported under the body to provide support for the body.

[0091] refer to Fig.11 As shown, the top surface of the body mounting portion 124 may be provided with a plurality of protrusions 124c, which are tooth-shaped and are circumferentially distributed on the top surface of the body mounting portion 124 with the third rotation axis L4 as the center, for cooperating with the body to enhance the connection strength between the body and the body mounting portion 124.

[0092] A plurality of vehicle body mounting portions 124 may be fixedly disposed on the main body 110. Figure 4 As shown, the first longitudinal beam 112a and the second longitudinal beam 112b are both provided with a body mounting portion 124 at one end away from the second cross beam 111b in the front-to-back direction, and the second cross beam 111b is also provided with a body mounting portion 124 at both ends in the left-to-right direction, so that there are multiple connection positions between the frame 100 and the body to ensure a stable connection between the two.

[0093] The vehicle body mounting portion 124 is disposed on the top of the cross beam 111 and the longitudinal beam 112 and extends at least in the vertical direction; the vehicle body mounting portion 124 includes a mounting seat having a vehicle body mounting hole 124 a.

The steering gear mounting bracket 130 is used to connect the vehicle's steering gear, so as to assemble the steering gear to the vehicle frame 100. The steering gear mounting bracket 130 is fixedly connected to the body 110. For example, the steering gear mounting bracket 130 can be fixedly arranged on both the first longitudinal beam 112a and the second longitudinal beam 112b by welding or the like, and the steering gear mounting bracket 130 is located between the first cross beam 111a and the second cross beam 111b in the front-rear direction. The steering gear mounting bracket 130 can be protruded along the height direction of the body and arranged on the upper surface of the first longitudinal beam 112a or the second longitudinal beam 112b, so that the steering gear can be assembled above the vehicle frame 100 during assembly, and the steering gear can be supported by the steering gear mounting bracket 130.

[0095] In some embodiments, reference Figure 2 As shown, the cross beam 111 may further include a third cross beam 111c. The third cross beam 111c is fixedly connected between the first longitudinal beam 112a and the second longitudinal beam 112b in the left-right direction, and is located on the side of the first cross beam 111a away from the second cross beam 111b in the front-to-back direction. More specifically, the third cross beam 111c is located outside the inter-beam space 110a in the horizontal direction, that is, the ends of the first longitudinal beam 112a and the second longitudinal beam 112b away from the second cross beam 111b in the front-to-back direction protrude from the first cross beam 111a and are connected to the third cross beam 111c. The first longitudinal beam 112a, the end of the second longitudinal beam 112b away from the second cross beam 111b, and the third cross beam 111c can be used to carry and install components such as a water pump, a compressor, etc. on the vehicle, thereby increasing the functionality of the frame 100.

[0096] In some embodiments, reference Figure 1 , Figure 4 and Fig.13 As shown, the compressor mounting bracket 140 can be fixedly arranged on the third cross beam 111c by welding, threaded fixing, etc. The compressor mounting bracket 140 is used to fix the compressor to the frame. The compressor mounting hole 141 can be provided on the compressor mounting bracket 140, and the compressor can be fixed to the compressor mounting bracket 140 at the compressor mounting hole 141 by threaded connection, etc. The compressor mounting bracket 140 can be fixed only on the third cross beam 111c, or can be fixed between the third cross beam 111c and the first cross beam 111a, so that the compressor can be stably installed on the frame 100.

[0097] In some embodiments, reference Figure 1 , Figure 4 and Fig.14As shown, the end of the first longitudinal beam 112a or the second longitudinal beam 112b close to the third cross beam 111c can be fixedly provided with a water pump mounting bracket 150 by means of threaded connection or the like, and the water pump mounting bracket 150 is used to fix the water pump, so as to assemble the water pump to the vehicle frame 100. The water pump mounting bracket 150 can be provided with a water pump mounting hole 151, so that the water pump is fixed to the vehicle frame 100 by means of threaded connection at the water pump mounting hole 151.

[0098] In some embodiments, reference Figure 1 , Figure 4 and Fig.14 As shown, the frame also includes: a cooling module mounting bracket 160. The cooling module mounting bracket 160 is used to fix the cooling module. In the present application, the cooling module can be an assembly of components such as pipes, heat exchangers, fans, etc. in the vehicle that are used to connect to a water pump, a compressor, etc., and is used to dissipate heat from the powertrain and other parts of the vehicle. The cooling module mounting bracket 160 is fixedly connected to the body 110, so that the cooling module can be assembled to the frame 100. The cooling module mounting bracket 160 can be provided with a cooling module mounting hole 161, so that the cooling module is fixed to the frame 100 at the cooling module mounting hole 161 by threaded connection.

[0099] In some embodiments, the cooling module mounting bracket 160 can be fixed to the side of the third cross beam 111c away from the second cross beam 111b in the left-right direction by means of threaded connection or the like, or the cooling module mounting bracket 160 can be fixed to the end of the first longitudinal beam 112a or the second longitudinal beam 112b away from the second cross beam 111b in the left-right direction by means of threaded connection or the like. It can be understood that when the frame 100 of the present embodiment is used as a front subframe, this arrangement makes the cooling module close to the front of the vehicle and away from the cabin. Alternatively, when the frame 100 of the present embodiment is used as a rear subframe, this arrangement makes the cooling module close to the rear of the vehicle and away from the cabin. Therefore, this arrangement can keep the cooling module away from the cabin and ensure the heat exchange and cooling effect.

[0100] In some embodiments, reference Figure 1 As shown, the vehicle frame 100 further includes a stabilizer bar mounting bracket 170. The stabilizer bar mounting bracket 170 is fixedly connected to the body 110, or is integrally formed with the body 110. Specifically, the stabilizer bar mounting bracket 170 is provided at one end of the first longitudinal beam 112a and the second longitudinal beam 112b close to the third cross beam 111c. The stabilizer bar mounting bracket 170 is used to connect the stabilizer bar, so as to assemble the stabilizer bar to the vehicle frame 100. The stabilizer bar mounting bracket 170 is provided on the upper surface of the first longitudinal beam 112a or the second longitudinal beam 112b in the height direction of the frame, so that the stabilizer bar is assembled above the vehicle frame 100 during assembly, and the stabilizer bar is supported by the stabilizer bar mounting bracket 170.

[0101] Those skilled in the art will appreciate that when the frame 100 is assembled into a vehicle, the longitudinal beams 112 may be disposed on the left and right sides of the vehicle, and the cross beams 111 may be disposed on the front and rear sides of the vehicle. In this case, the left and right direction may correspond to the left and right direction, and the front and rear direction may correspond to the front and rear direction. Accordingly, the height direction of the body 110 is the up and down direction.

[0102] In the embodiment of the present application, the first cross beam 111a is arranged between the second cross beam 111b and the third cross beam 111c. When the frame 100 is subjected to external force from the front or rear, the third cross beam 111c or the first cross beam 111a can absorb part of the impact, thereby reducing the possibility of damage to the second cross beam 111b, thereby avoiding failure of the connection between the powertrain mounted on the second cross beam 111b through the powertrain suspension and the frame 100, which is beneficial to improving the safety of the frame 100.

[0103] In some embodiments, one end of the first longitudinal beam 112a close to the third cross beam 111c can be tilted in the left-right direction toward a side away from the second longitudinal beam 112b, and one end of the second longitudinal beam 112b close to the third cross beam 111c can be tilted in the left-right direction toward a side away from the first longitudinal beam 112a, so that when the ends of the first longitudinal beam 112a and the second longitudinal beam 112b receive an impact, they have a tendency to move away from each other in the left-right direction. When the frame 100 is used as a front sub-frame or a rear sub-frame and connected to the main frame, this arrangement is beneficial to reducing the transmission of impact force in the front-to-rear direction of the sub-frame to the main frame, thereby improving the safety of the frame 100.

[0104] In some embodiments, the vehicle body mounting portion 124 on the first longitudinal beam 112a and the second longitudinal beam 112b may be fixedly disposed or integrally formed on one end of the first longitudinal beam 111a protruding from the first longitudinal beam 111a along the front-to-back direction. At the same time, one end of the first longitudinal beam 112a close to the third cross beam 111c can be tilted in the left-right direction toward the side away from the second longitudinal beam 112b, and one end of the second longitudinal beam 112b close to the third cross beam 111c can be tilted in the left-right direction toward the side away from the first longitudinal beam 112a, and one end of the second cross beam 111b in the left-right direction protrudes from the first longitudinal beam 112a, and the other end protrudes from the second longitudinal beam 112b, and the body mounting portion 124 on the second cross beam 111b is fixedly connected or integrally formed with the portion of the second cross beam 111b corresponding to the protrusion of the first longitudinal beam 112a or the second longitudinal beam 112b, so that the distance between these body mounting portions 124 and the body mounting portions 124 on the second cross beam 111b in the front-to-back direction is large, and the distance between the body mounting portions 124 on the first longitudinal beam 112a, the second longitudinal beam 112b and the second cross beam 111b in the left-right direction is large. This method can improve the connection stability between the frame 100 and the vehicle body.

[0105] In some embodiments, reference Figure 1 and Figure 4 As shown, the frame also includes an energy absorption box 180. The energy absorption box 180 is fixedly connected to the end of the longitudinal beam 112. Specifically, the ends of the first longitudinal beam 112a and the second longitudinal beam 112b away from the second cross beam 111b are fixedly connected with the energy absorption box 180. The energy absorption box 180 can enable the frame to withstand more external impacts and improve the safety of the frame 100.

[0106] In some embodiments, reference Figure 2 As shown, the body 110 is provided with a guard plate mounting hole 110b for connecting the guard plate. Specifically, the first longitudinal beam 112a and the second longitudinal beam 112b are both provided with a plurality of guard plate mounting holes 110b at intervals in the front-to-back direction, and each guard plate mounting hole 110b can be a threaded hole, so that the guard plate is assembled to the frame 100 by threaded connection.

[0107] The guard plate mounting hole 110b penetrates the bottom surface of the first longitudinal beam 112a and the second longitudinal beam 112b in the height direction of the frame, that is, the guard plate can be fixedly installed at the bottom of the first longitudinal beam 112a and the second longitudinal beam 112b, so that the guard plate is used to protect the parts above. The guard plate mounting bracket 110c can also be fixedly installed on the bottom surface of the first longitudinal beam 112a and / or the second longitudinal beam 112b by welding or other methods, and the guard plate mounting hole 110b is formed on the guard plate mounting bracket 110c, so that the guard plate is assembled to the body 110 using the guard plate mounting hole 110b, so that there is a height difference between the guard plate and the parts such as suspension and suspension assembled on the frame 100, which is convenient for arranging and assembling various parts in the space where the frame 100 is located.
