Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are 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 of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0028] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0029] The terms "include", "comprise" or any other variant thereof in the description and claims of the present application are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or terminal device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, article or terminal device including the said element.

[0030] The following details a frame assembly, a body frame, and a vehicle provided by the present application by listing specific embodiments.

[0031] Figures 1 to 3 The schematic diagrams of several frame assemblies in the embodiments of the present application are shown. Referring to Figures 1 to 3 , an embodiment of the present application provides a frame assembly. The frame assembly includes a subframe 1 and an oil pump assembly 2. The subframe 1 includes a first cross beam 11, and the first cross beam 11 is located on one side of the subframe 1 close to the front or rear of the vehicle. The oil pump assembly 2 is fixedly installed directly below the first cross beam 11.

[0032] Among them, the subframe is a bracket that supports the front and rear axles and the suspension. The axles and the suspension are connected to the main frame of the vehicle through the subframe to form a complete frame structure. The subframe can block vibrations and noises, preventing them from directly entering the passenger compartment, thereby helping to improve the riding comfort and driving stability.

[0033] The subframe includes cross beams and longitudinal beams. The longitudinal beams are the components longitudinally arranged in the subframe, constituting the main structure of the subframe, mainly playing a supporting role. In practical applications, the longitudinal beams may be designed in sections according to the vehicle model and design requirements. The cross beams are the components transversely arranged in the subframe, respectively connected to the longitudinal beams on the left and right sides to enhance the overall rigidity and stability of the subframe. It should be noted that in the embodiments of the present application, the longitudinal direction refers to the direction along the length of the vehicle body, as shown by the X direction in Figures 1 to 3 , the transverse direction refers to the direction along the width of the vehicle body, as shown by the Y direction in Figures 1 to 3 , and in addition, the height direction of the vehicle body is shown by the Z direction in Figure 1 .

[0034] The number and arrangement of the cross beams may vary according to the vehicle model and design requirements, but they are usually arranged at the front and rear, corresponding to form a front cross beam and a rear cross beam. The first cross beam 11 in the embodiments of the present application refers to the front cross beam in the subframe 1. If the subframe 1 is a front subframe, the first cross beam 11 is the cross beam located on the side close to the front of the vehicle. If the subframe 1 is a rear subframe, the first cross beam 11 is the cross beam located on the side close to the rear of the vehicle. Among them, parts of the cross beams and longitudinal beams can be designed as hollow structures to reduce the total weight of the subframe 1, which is beneficial to the lightweight design of the frame assembly.

[0035] In the embodiments of the present application, the oil pump assembly 2 is fixedly installed directly below the first cross beam 11. Figure 1 The schematic diagram of the frame assembly from a top view is shown. Figure 2 The schematic diagram of the frame assembly from a bottom view is shown. Figure 3 The front view of the frame assembly from a top view is shown. Referring to Figures 1 to 3, the projection of the oil pump assembly 2 in the vehicle body height direction mostly coincides with the projection of the first cross member 11 in the vehicle body height direction, greatly reducing the space occupied by the oil pump assembly 2 and the first cross member 11 longitudinally in the vehicle, which is beneficial to the layout of other components longitudinally in the vehicle, thus facilitating the optimization and improvement of the vehicle structure. At the same time, part or all of the oil pump assembly 2 is hidden under the first cross member 11, greatly reducing the encroachment of the oil pump assembly 2 on the longitudinal crush space of the vehicle body, thereby helping to reduce the degree of deformation or damage of the front or rear of the vehicle when a collision occurs, and improving the safety performance of the vehicle. It should be noted that if the longitudinal dimension of the first cross member 11 is greater than the longitudinal dimension of the oil pump assembly 2, all of the oil pump assembly 2 can be hidden under the first cross member 11; if the longitudinal dimension of the first cross member 11 is less than the longitudinal dimension of the oil pump assembly 2, part of the oil pump assembly 2 can be hidden under the first cross member 11.

[0036] In addition, in the embodiment of the present application, the oil pump assembly 2 is installed and fixed directly below the first cross member 11, rather than installing and fixing the oil pump assembly 2 above the first cross member 11, which can also prevent the oil pump assembly 2 from interfering with components such as the fan and air conditioning compressor above the subframe 1, thus ensuring the normal operation of the oil pump assembly 2.

[0037] Optionally, in some embodiments of the present application, referring to Figures 1 to 3 , the oil pump assembly 2 includes an oil pump body 21 and a bracket 22; the bracket 22 is provided at at least one end of the oil pump body 21 along its length direction, and the oil pump body 21 is fixedly connected to the first cross member 11 through the bracket 22.

[0038] Among them, the oil pump body 21 is the main component of the oil pump assembly 2, which is used to adjust the movement of the suspension. The bracket 22 is provided at at least one end of the oil pump body 21 along its length direction, and the length direction of the oil pump body 21 is as shown by the Y direction in Figures 1 to 3 . As shown in Figures 1 to 3 , the vehicle frame assembly includes two oil pump bodies 21, the two oil pump bodies 21 are arranged in parallel and connected to each other. One oil pump body 21 is used to adjust the suspension on the left side of the vehicle, and the other oil pump body 21 is used to adjust the suspension on the right side of the vehicle. The bracket 22 is fixedly connected to one end of each oil pump body 21 and is located on the side where the two oil pump bodies 21 are away from each other. The bracket 22 is fixedly connected to the first cross member 11, thus realizing the connection between the oil pump body 21 and the first cross member 11 through the bracket 22. Of course, the bracket 22 can also be fixedly connected to both ends of each oil pump body 21, so that each oil pump body 21 is fixedly connected to the first cross member 11 through two brackets 22. The figure shows a schematic diagram of the oil pump assembly 2 including two brackets 22. The sizes of the two brackets 22 are reasonably set to meet the connection requirements of the oil pump body 21, which helps to control the number of components of the oil pump assembly 2 and save the layout cost of the oil pump assembly 2.

[0039] In addition, the fixed connection between the oil pump body 21 and the bracket 22 and the fixed connection between the bracket 22 and the first crossbeam 11 can be assembled and connected by fasteners such as bolts and screws, or can be laser welded, or can also be a limiting snap connection method, etc. The embodiments of the present application do not limit this.

[0040] In the embodiments of the present application, the oil pump body 21 is fixedly connected to the first crossbeam 11 through the bracket 22, without improving the structural shape of the oil pump body 21 itself, which helps to control the design cost of the oil pump body 21. At the same time, the bracket 22 can play a certain limiting role in the length direction of the oil pump body 21, which helps to improve the installation stability of the oil pump body 21, thereby ensuring the normal operation of the oil pump body 21.

[0041] Since the oil pump assembly is connected to a motor, and the motor will generate a certain amount of movement during operation, the oil pump assembly also needs to have a certain amount of movement to adapt to the operation of the motor and avoid interference with the motor. In the embodiments of the present application, the movement amount of the oil pump body 21 relative to the first crossbeam 11 in the vehicle body length direction is about ±9 mm, the movement amount in the vehicle body width direction relative to the first crossbeam 11 is about ±5 mm, and the movement amount in the vehicle body height direction relative to the first crossbeam 11 is about ±9 mm; the movement amount of the bracket 22 relative to the first crossbeam 11 in the vehicle body length direction is about ±1.5 mm, the movement amount in the vehicle body width direction relative to the first crossbeam 11 is about ±1.5 mm, and the movement amount in the vehicle body height direction relative to the first crossbeam 11 is ±3 mm, so as to ensure that the movement envelope of the oil pump assembly 1 and the peripheral clearance ≥ 10 mm, meeting the working requirements of the motor.

[0042] Optionally, in some embodiments of the present application, referring to Figure 2 and Figure 3 , the bracket 22 is provided with a first connection portion 221 and a second connection portion 222; the first connection portion 221 extends along the length direction of the oil pump body 21, and the bracket 22 is fixedly connected to the oil pump body 21 through the first connection portion 221; the second connection portion 222 extends along the height direction of the oil pump body 21, and the bracket 22 is fixedly connected to the first crossbeam 11 through the second connection portion 222.

[0043] Among them, the length direction of the oil pump body 21 is as shown by the Y direction in Figures 1 to 3 , and the height direction of the oil pump body 21 is as shown by Figures 1 to 3As shown in the Z direction in the figure, the first connecting portion 221 extends along the length direction of the oil pump body 21, and the second connecting portion 222 extends along the height direction of the oil pump body 21, so that the oil pump body 21 is connected to the bracket 22 and the bracket 22 is connected to the first cross beam 11 in two different directions. Since both the oil pump body 21 and the bracket 22 are arranged below the first cross beam 11, such a setting makes rational use of the spatial layout among the oil pump body 21, the bracket 22, and the first cross beam 11, and is more convenient for realizing the smooth connection among them.

[0044] In addition, the first connecting portion 221 extends along the length direction of the oil pump body 21, so that the connecting portion between the oil pump body 21 and the bracket 22 is greatly affected by the external force along the length direction of the oil pump body 21 and is less affected by the external force along the height direction of the oil pump body 21. While the second connecting portion 222 extends along the height direction of the oil pump body 21, so that the connecting portion between the bracket 22 and the first cross beam 11 is less affected by the external force along the length direction of the oil pump body 21 and is more affected by the external force along the height direction of the oil pump body 21. That is to say, the environments in which the first connecting portion 221 and the second connecting portion 222 are affected by external forces are different, which is more conducive to the dispersion and absorption of forces, thereby further improving the connection reliability between the oil pump body 21 and the bracket 22 and between the bracket 22 and the first cross beam 11.

[0045] Furthermore, as Figure 2 and Figure 3 shown, there are two first connecting portions 221 and two second connecting portions 222 on the bracket 22. The two first connecting portions 221 are arranged at intervals, and the bracket 22 is fixedly connected to the oil pump body 21 through the two first connecting portions 221. The two second connecting portions 222 are arranged at intervals, and the bracket 22 is fixedly connected to the first cross beam 11 through the two second connecting portions 222. At the same time, the two first connecting portions 221 are respectively fixedly connected to both sides of the oil pump body 21 along its width direction ( Figures 1 to 3 the X direction in the figure), and the two second connecting portions 222 are respectively fixedly connected to both sides of the first cross beam 11 along its width direction ( Figures 1 to 3 the X direction in the figure) to disperse the force and further improve the connection reliability between the oil pump body 21 and the bracket 22 and between the bracket 22 and the first cross beam 11.

[0046] Optionally, in some embodiments of the present application, referring to Figure 2 and Figure 3 , the oil pump assembly 2 further includes a buffer member 23; the buffer member 23 is arranged on the first connecting portion 221 and / or the second connecting portion 222.

[0047] Among them, the buffer member 23 can be a rubber buffer pad, a silica gel buffer pad, a spring, etc., and has a certain elastic deformation ability. The buffer member 23 is disposed on the first connecting portion 221 and / or the second connecting portion 222. When the first connecting portion 221 and / or the second connecting portion 222 is subjected to an external force impact, the buffer member 23 can absorb part of the impact force through its own deformation, thereby realizing the buffering function, which helps to improve the connection reliability of the first connecting portion 221 and / or the second connecting portion 222, that is, to improve the connection reliability between the oil pump body 21 and the bracket 22 and between the bracket 22 and the first cross beam 11. At the same time, the buffer member 23 can also play a certain role in vibration isolation, which helps to reduce the noise of the connection between the oil pump assembly 2 and the first cross beam 11, thereby improving the vibration isolation and noise reduction performance of the vehicle frame assembly.

[0048] If the buffer member 23 is only disposed on the first connecting portion 221 or the second connecting portion 222, only the primary buffering and vibration isolation of the oil pump assembly 2 can be realized, but it helps to reduce the number of parts of the oil pump assembly 2, control the overall cost of the oil pump assembly 2, and is more convenient for the installation of the oil pump assembly 2. If the buffer member 23 is respectively disposed on the first connecting portion 221 and the second connecting portion 222, the secondary buffering and vibration isolation of the oil pump assembly 2 can be realized, effectively improving the buffering and vibration isolation ability after the installation of the oil pump assembly 2, which helps to extend the service life of the oil pump assembly 2.

[0049] Optionally, in some embodiments of the present application, the vehicle frame assembly further includes a protective beam 3; Figure 4 The schematic diagram showing that the vehicle frame assembly in the embodiment of the present application includes the protective beam 3 is referred to Figure 4 , the protective beam 3 is connected to the first cross beam 11 and is at least partially disposed below the oil pump body 21, and a protective space is formed between the part of the protective beam 3 located below the oil pump body 21 and the oil pump body 21.

[0050] Among them, a part of the protective beam 3 is disposed below the oil pump body 21, and the length dimension of the protective beam 3 (the dimension along the Figures 1 to 3 X direction in it) is greater than the length dimension of the oil pump body 21. The projection of the oil pump body 21 in the vehicle body height direction partially coincides with the projection of the protective beam 3 in the vehicle body height direction. The two ends of the protective beam 3 extend along the vehicle body height direction and are fixedly connected to the first cross beam 11. It can be realized by means of fastener assembly connection, laser welding, etc. In the embodiment of the present application, connecting plates 33 are provided at both ends of the protective beam 3 along its length direction. The protective beam 3 is welded to the connecting plates 33, and the other side of the connecting plates 33 is assembled and connected to the first cross beam 11 through fasteners, thereby realizing the fixed connection between the protective beam 3 and the first cross beam 11 through the connecting plates 33.

[0051] The protective beam 3 can prevent the bottom of the oil pump body 21 from being scratched by particles such as stones on the ground, thereby protecting the bottom of the oil pump body 21 and extending the service life of the oil pump body 21. At the same time, a protective space is formed between the protective beam 3 and the oil pump body 21, that is, the protective beam 3 does not directly contact the bottom of the oil pump body 21, preventing the protective beam 3 from rubbing or colliding with the bottom of the oil pump body 21 when the vehicle encounters a bumpy road condition, thereby further strengthening the protection of the bottom of the oil pump body 21, improving the use reliability of the oil pump body 21, and improving the vehicle maintenance economy index.

[0052] Optionally, in some embodiments of the present application, referring to Figure 4 , the protective beam 3 includes a first beam body 31 and a second beam body 32; the first beam body 31 and the second beam body 32 are arranged at intervals, and the first beam body 31 is located on the side close to the vehicle head or the vehicle tail.

[0053] Wherein, if the subframe 1 is a front subframe, the first beam body 31 is located on the side close to the vehicle head; if the subframe 1 is a rear subframe, the first beam body 31 is located on the side close to the vehicle tail. The first beam body 31 can protect the front side of the bottom of the oil pump body 21. For example, when the vehicle encounters steps, bumps or other working conditions in the front during driving, if the vehicle continues to move forward, the first beam body 31 will contact the steps or bumps, etc., thereby preventing the steps or bumps from scratching the front side of the bottom of the oil pump body 21 and realizing the protection of the bottom of the oil pump body 21. The second beam body 32 can protect the middle part of the bottom of the oil pump body 21. For example, when there are steps or bumps under the vehicle when it is parked, the second beam body 32 will contact the steps or bumps, etc., thereby preventing the steps or bumps from scratching the bottom of the oil pump body 21 and realizing the protection of the bottom of the oil pump body 21.

[0054] The first beam body 31 and the second beam body 32 are arranged at intervals, that is, there is a certain gap between the first beam body 31 and the second beam body 32. Such a setting can not only meet the protection requirements of the protective beam 3 for the oil pump body 21, but also help save the consumables of the protective beam 3, control the overall cost of the protective beam 3. At the same time, it also helps to reduce the total weight of the protective beam 3, which is beneficial to the lightweight design of the frame assembly. In addition, the number of the first beam body 31 and the second beam body 32 can be one, two or more respectively, which is specifically set according to the size of the oil pump body 21. The interval distance between the first beam body 31 and the second beam body 32 can also be set according to the size of the oil pump body 21, as long as it can provide an effective protection effect for the oil pump body 21. The embodiments of the present application do not limit this.

[0055] Furthermore, the first beam body 31 and the second beam body 32 can be prismatic beam bodies or plate-shaped beam bodies to increase the area of the beam bodies in the direction parallel to the ground and provide a better protection effect for the oil pump body 21.

[0056] Optionally, in some embodiments of the present application, with reference to Figure 4 , an obtuse angle is formed between the first beam body 31 and the second beam body 32, and the second beam body 32 is arranged parallel to the ground.

[0057] Specifically, the second beam body 32 is arranged parallel to the ground, and an obtuse angle is formed between the first beam body 31 and the second beam body 32, which means that the first beam body 31 is inclined towards the front or rear of the vehicle. Since the impact force received by the first beam body 31 comes from the front or rear side of the vehicle, and the direction of the impact force is along the length direction of the vehicle body, therefore, arranging the first beam body 31 to be inclined towards the front or rear of the vehicle helps to disperse the impact force, avoid stress concentration, thereby improving the impact resistance of the first beam body 31 and providing guarantee for the protection effect of the first beam body 31 on the oil pump body 21.

[0058] It should be noted that the size of the obtuse angle between the first beam body 31 and the second beam body 32 in the embodiments of the present application can be set according to the specific positions of the first beam body 31, the second beam body 32 and the oil pump body 21, and the embodiments of the present application do not limit this.

[0059] Optionally, in some embodiments of the present application, at least one of the first beam body 31 and the second beam body 32 is a hollow beam.

[0060] Among them, both the first beam body 31 and the second beam body 32 can be set as hollow beams, or one of the first beam body 31 and the second beam body 32 can be set as a hollow beam and the other can be set as a solid beam. If both the first beam body 31 and the second beam body 32 adopt hollow beams, it is more beneficial to save the material cost of the first beam body 31 and the second beam body 32, and further save the total cost of the frame assembly. At the same time, it is more beneficial to reduce the weight of the first beam body 31 and the second beam body 32 and realize the lightweight design of the frame assembly. If one of the first beam body 31 and the second beam body 32 is a solid beam, the solid beam has higher strength and stiffness, which is more helpful to improve the structural stability of the beam body, enhance the impact resistance of the beam body, and ensure the protection effect of the beam body on the oil pump body 21.

[0061] Optionally, in some embodiments of the present application, with reference to Figure 1 , a part of the first cross beam 11 is recessed upward along the height direction of the vehicle body to form an avoidance space 12, and a part of the oil pump assembly 2 is located in the avoidance space 12.

[0062] Specifically, Figure 1The schematic diagram shows the middle area of the first crossbeam 11 being recessed along its length direction to form an avoidance space 12. The first crossbeam 11 is directly processed into a beam body with a recessed structure through an integral molding process. After the first crossbeam 11 is recessed, the avoidance space 12 is formed. The top of the oil pump body 21 is arranged in the avoidance space 12. The degree of recess of the first crossbeam 11 is set according to the size of the oil pump body 21. If the size of the oil pump body 21 is larger, the degree of recess of the first crossbeam 11 is larger; if the size of the oil pump body 21 is smaller, the degree of recess of the first crossbeam 11 is smaller. The existence of the avoidance space 12 can provide a more sufficient layout space for the oil pump body 21, making it more convenient for the installation and layout of the oil pump body 21. At the same time, it can also raise the installation height of the oil pump body 21 to a certain extent, reducing the probability and degree of the bottom of the oil pump body 21 being scratched, thereby extending the service life of the oil pump body 21.

[0063] The embodiment of the present application also provides a vehicle body frame, including the vehicle frame assembly of any one of the foregoing.

[0064] Specifically, in addition to including the vehicle frame assembly of the foregoing embodiment, the vehicle body frame also includes vehicle body covering parts such as doors, roofs, vehicle body side walls, and vehicle tails. The vehicle body frame forms the main structure of the vehicle, providing basic support and load-bearing functions for the vehicle to ensure the stability and safety of the vehicle under various driving conditions. The vehicle body frame includes a load-bearing body, which has no independent vehicle frame. The vehicle frame assembly of the foregoing embodiment and the vehicle body are of an integral structure, which is light in weight, high in space utilization rate, and good in comfort, but relatively low in torsional stiffness. The vehicle body frame also includes a non-load-bearing body, which has an independent vehicle frame. The vehicle frame assembly of the foregoing embodiment and the vehicle body are assembled together to form a complete vehicle body frame, which is high in rigidity and durability, but large in weight and relatively poor in comfort.
