Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0020] Larger vehicles, while increasing passenger compartment space, correspondingly reduce the front engine compartment space to ensure optimal overall vehicle space utilization. Based on current vehicle engine compartment layouts and to meet market styling demands, the front end frame plays a crucial role. The front of the front end frame connects to the front taillights, front bumper, and headlights, while the rear connects to the ventilation covers and air conditioning ducts. Therefore, the front end frame requires multiple mounting points to connect to other vehicle components, resulting in a complex frame design that cannot be achieved through one-piece injection molding. In the confined space of the front engine compartment, workers' inspection tools cannot reach the parts requiring inspection, leading to difficulties in daily inspection and maintenance. After a collision, even if only part of the front end frame is damaged, the entire front end frame must be replaced, increasing repair costs.

[0021] Please see Figure 1 and Figure 2 This application provides a frame structure, including a body 10 and a connector 20. The body 10 is a one-piece injection-molded structure, and includes a plurality of first mounting portions 11 arranged at intervals. The connector 20 is a one-piece injection-molded structure, and includes a support portion 21 and a plurality of second mounting portions 22 arranged at intervals. The support portion 21 is detachably connected to the body 10, and the plurality of second mounting portions 22 are disposed on the support portion 21. The plurality of second mounting portions 22 and the plurality of first mounting portions 11 are used to connect components on a vehicle.

[0022] Understandably, the main body 10, as the basic load-bearing component of the frame structure, can be integrally injection molded from polypropylene material. The overall structure of the main body 10 is designed according to the installation space and component layout requirements of the vehicle's front engine compartment, and it has multiple first mounting parts 11, which achieve stable connections with certain vehicle components. The multiple first mounting parts 11 are arranged at intervals, the spacing of which can be set according to the size of the connected components, installation position requirements, and clearance space between components, ensuring that each component does not interfere with others after installation and maintains its own functional stability. The specific structure of the first mounting part 11 can be set according to actual connection requirements, for example, it can be set as a threaded hole, a snap-fit ​​seat, or a bolt connection seat. The main body 10 can directly connect to vehicle components such as the front bumper and the left and right front combination headlights through these first mounting parts 11, providing a stable mounting reference for these components.

[0023] The connector 20 can also be integrally injection molded from polypropylene material. As an auxiliary connecting component of the frame structure, the connector 20, through its detachable connection with the main body 10, forms a complete frame installation system to meet the installation needs of more components. The load-bearing part 21 is the main load-bearing structure of the connector 20, and multiple second mounting parts 22 are disposed on the load-bearing part 21, providing installation positions for multiple components. The multiple second mounting parts 22 are arranged at intervals, and their arrangement and structural form can be set according to the specific installation requirements of the connected components, and can be threaded holes, snap-fit ​​seats, or other suitable connecting structures. The connector 20 can achieve stable connection with components such as ventilation covers, air conditioning ducts, and front through-lights through the multiple second mounting parts 22. These components are indirectly installed onto the main body 10 through the connector 20, forming a complete assembly system for the front of the vehicle together with the components directly installed on the main body 10. Multiple second mounting parts 22 and multiple first mounting parts 11 together form the mounting points of the frame structure, enabling the frame structure to meet the installation requirements of multiple components in the front engine compartment of the vehicle. This solves the problem that traditional one-piece frames cannot be integrally injection molded due to the large number of mounting points and complex structure, and meets the connection requirements while facilitating the processing of the frame structure.

[0024] Furthermore, for the limited space in the front engine compartment, the connector 20 can be detached from the main body 10 for inspection and maintenance, increasing the maintenance space within the front engine compartment without disassembling the main body 10. This reduces maintenance time and costs, and facilitates maintenance. In the event of a collision, if the components connected to the connector 20 are damaged, the connector 20 can be removed, and only the components connected to it can be replaced, without replacing the entire frame structure. This reduces component costs and improves the economics of vehicle maintenance.

[0025] Please see Figure 1 , Figure 2 and Figure 3 In conjunction with the above embodiments, in some embodiments, the connector 20 further includes a fixing part 23, which is connected to the bearing part 21, and the bearing part 21 is detachably connected to the body 10 through the fixing part 23.

[0026] It is understood that the fixing part 23 and the supporting part 21 are integrally injection molded structures, which can ensure the connection strength and prevent the fixing part 23 from separating from the supporting part 21 due to external forces during use. The setting position of the fixing part 23 needs to be adapted to the connection area of ​​the body 10, and can be set as a plate, block or other adaptable shape according to actual assembly requirements. In this application, the fixing part 23 is preferably set as a plate structure, which can increase the contact area with the connection surface of the body 10, improve the stability after connection, and reduce the local stress concentration. The supporting part 21 is detachably connected to the body 10 through the fixing part 23, such as bolt connection, snap connection, etc. This application uses bolt connection to ensure the reliability of the connection and the convenience of assembly and disassembly. When using bolt connection, the fixing part 23 has a through threaded hole, and the corresponding position of the body 10 also has a matching threaded hole. During assembly, the bearing part 21 and the body 10 can be fixedly connected by passing the bolt through the threaded hole on the fixing part 23 and the body 10 and tightening it. When disassembly is required, the connecting part 20 can be separated from the body 10 as a whole by simply unscrewing the bolt.

[0027] Please see Figure 1 , Figure 2 and Figure 3 In conjunction with the above embodiments, in some embodiments, there are multiple fixing parts 23, and the multiple fixing parts 23 are respectively connected to different sides of the bearing part 21.

[0028] Understandably, multiple fixing parts 23 are connected to different sides of the bearing part 21. For example, a fixing part 23 is provided on the left, right and middle of the bearing part 21, so that when the bearing part 21 is connected to the body 10, the force can be evenly distributed in different areas of the bearing part 21, avoiding excessive force on a single connection point that could lead to loosening of the connection or structural damage, and ensuring the overall stability of the frame structure.

[0029] Please see Figure 3 and Figure 4 In conjunction with the above embodiments, in some embodiments, the body 10 has a positioning hole 12, and the connector 20 further includes a positioning part 24, which is connected to the side of the fixing part 23 facing the body 10, and the positioning part 24 is embedded in the positioning hole 12.

[0030] It is understood that positioning holes 12 are provided on the main body 10 corresponding to the assembly positions of the connector 20. The number of positioning holes 12 is consistent with the number of positioning parts 24 on the connector 20, and their sizes and shapes are perfectly matched. The positions of the positioning holes 12 correspond one-to-one with the positions of the positioning parts 24 on the fixing part 23, ensuring that the positioning parts 24 can be smoothly inserted into the positioning holes 12, while avoiding excessive gaps after insertion that could cause assembly loosening and reducing assembly deviations. The positioning parts 24 and the fixing parts 23 of the connector 20 are integrally injection molded structures. During the assembly of the frame structure, when it is necessary to install the connector 20 onto the body 10, the positioning part 24 should first be aligned with the positioning hole 12 on the body 10 and the positioning part 24 should be embedded into the positioning hole 12. This can quickly determine the installation position of the connector 20 on the body 10, avoid repeatedly adjusting the position of the connector 20 during assembly, and improve assembly efficiency. On the other hand, by engaging the positioning part 24 with the positioning hole 12, the connector 20 can be temporarily fixed to the body 10 before the fixing part 23 is connected to the body 10 by bolts, preventing the connector 20 from shifting during assembly and facilitating the subsequent alignment of the fixing part 23 with the threaded hole on the body 10.

[0031] Please see Figure 5 and Figure 6 In conjunction with the above embodiments, in some embodiments, the positioning part 24 includes a first segment 241 and a second segment 242. The first segment 241 is connected to the side of the fixing part 23 facing the body 10. The second segment 242 is connected to the side of the first segment 241 away from the fixing part 23, and the outer diameter of the second segment 242 gradually decreases from the fixing part 23 to the body 10.

[0032] Understandably, the first segment 241 has a cylindrical structure, with one end fixedly connected to the surface of the fixing part 23 facing the body 10, and the other end connected to the second segment 242. The outer diameter of the first segment 241 needs to match the diameter of the positioning hole 12 to ensure that the first segment 241 can smoothly enter the positioning hole 12 and form a certain fit with the inner wall of the positioning hole 12 after insertion, avoiding excessive gaps that could cause positioning deviation. The second segment 242 is connected to the end of the first segment 241 that is away from the fixing part 23, and is generally frustum-shaped or conical. The outer diameter of the upper end of the second segment 242 is the same as that of the first segment 241, ensuring a smooth connection between the two segments without obvious steps, while the outer diameter of the lower end is reduced to slightly smaller than the diameter of the positioning hole 12. This gradual outer diameter setting can play a guiding role during assembly. When the positioning part 24 is aligned with the positioning hole 12, the thinner lower end of the second segment 242 will enter the positioning hole 12 first. Even if there is a slight deviation in the initial alignment, the inclined outer wall of the second segment 242 can automatically adjust its direction along the edge of the positioning hole 12, guiding the entire positioning part 24 to be embedded accurately step by step. This eliminates the need for workers to repeatedly fine-tune the alignment, greatly reducing the difficulty of assembly and improving efficiency during assembly.

[0033] Please see Figure 2 In conjunction with the above embodiments, in some embodiments, the connector 20 further includes a reinforcing part 25, which is connected to the side of the fixing part 23 away from the body 10 and is connected to the bearing part 21.

[0034] It is understandable that the reinforcing part 25, the fixing part 23, and the load-bearing part 21 are integrally injection molded structures, forming a seamless whole structure after molding. This arrangement avoids loosening or breakage between the reinforcing part 25 and the fixing part 23 and load-bearing part 21 due to weak connections, ensuring that the reinforcing part 25 can function stably for a long time. It also simplifies the production process, eliminating the need for secondary assembly through welding, bonding, or other methods. One side of the reinforcing part 25 is fixedly connected to the fixing part 23, and the other side is connected to the outer wall of the load-bearing part 21, forming a support structure between the fixing part 23 and the load-bearing part 21, thereby improving the stability of the connection between the fixing part 23 and the load-bearing part 21. The reinforcing part 25 is preferably configured as a triangular rib, but it can also be configured as a trapezoidal rib or an arc-shaped rib depending on the actual space requirements. The triangular structure itself has good resistance to deformation and can more efficiently distribute the force, improving the stability of the connection. Multiple reinforcing parts 25 can be provided on each fixing part 23. The distribution of the multiple reinforcing parts 25 should avoid the threaded holes or other connecting structures on the fixing part 23 to avoid affecting the normal assembly of the fixing part 23 and the body 10. During the use of the frame structure, the second mounting part 22 on the load-bearing part 21 will connect to vehicle components such as air conditioning ducts and ventilation covers. These components have a certain weight, and when the vehicle is in motion, vibration and bumps will exert downward or lateral forces on the load-bearing part 21, which can easily lead to stress concentration at the connection between the load-bearing part 21 and the fixing part 23. By connecting the fixing part 23 and the load-bearing part 21 with multiple reinforcing parts 25, the force on the load-bearing part 21 can be distributed to the fixing part 23, and then transmitted to the body 10 through the fixing part 23, reducing the situation of excessive local stress and thus preventing damage to the connection between the load-bearing part 21 and the fixing part 23.

[0035] Please see Figure 7 and Figure 8 In conjunction with the above embodiments, in some embodiments, the body 10 further includes a main body portion 13 and a stepped portion 14. A plurality of first mounting portions 11 are disposed on the main body portion 13. The stepped portion 14 protrudes from the side of the main body portion 13 facing the connector 20 and is detachably connected to the fixing portion 23.

[0036] It is understandable that the main body 13 is the main load-bearing structure of the body 10. Multiple first mounting parts 11 are evenly spaced on the main body 13. The specific form of the first mounting part 11 can be a mounting hole with internal thread. Its number, hole diameter and distribution position need to be compatible with the mounting interface of the parts to be installed in the front engine compartment of the vehicle, such as the front combination headlights, front bumper, etc. The step portion 14 is designed to enhance the stability of the connection between the main body 10 and the connector 20. It protrudes from the surface of the main body 13 facing the connector 20. The step portion 14 creates a locally thickened structure in the corresponding area of ​​the main body 10. The protruding step portion 14 makes the thickness of the connection between the main body 10 and the fixing part 23 significantly greater than the thickness of other parts of the main body 13. By connecting the fixing part 23 to the thicker part of the main body 10, compared to directly connecting the fixing part 23 to the thinner surface of the main body 13, the structure of the thickened area has higher strength and can better withstand the force transmitted by the fixing part 23. This effectively avoids damage such as cracking or denting at the connection point on the main body 10 due to excessive force, further improving the overall durability of the frame structure.

[0037] Please see Figure 5 and Figure 9 In conjunction with the above embodiments, in some embodiments, the support portion 21 includes a plurality of support layers 211, which are arranged along a first direction X, and each second mounting portion 22 is disposed on the support layer 211. The first direction X is the height direction of the support portion 21.

[0038] It is understandable that multiple load-bearing layers 211 are arranged along the first direction X, and each load-bearing layer 211 has a different height. This layered arrangement allows the components to be installed on load-bearing layers 211 at different heights, avoiding the problems of installation crowding and mutual interference caused by all components being concentrated on the same plane, and improving space utilization by utilizing the vertical space.

[0039] Please see Figure 5 and Figure 9 In conjunction with the above embodiments, in some embodiments, the support portion 21 further includes at least one partition 212, and at least one partition 212 is disposed in at least one support layer 211. The partition 212 divides the corresponding support layer 211 into a plurality of mounting units 213, and each second mounting portion 22 is disposed on a mounting unit 213.

[0040] Understandably, the partition 212 can be arranged horizontally within the load-bearing layer 211, dividing the originally monolithic load-bearing layer 211 into multiple independent mounting units 213. The vertical plate-like structure of the partition 212 acts as a reinforcing rib, improving the load-bearing layer 211's resistance to bending and deformation, preventing deformation caused by the weight of the installed components or vehicle vibration, and extending the service life of the load-bearing part 21. Each second mounting part 22 is respectively set on a mounting unit 213, allowing components to be connected to a separate mounting unit 213, reducing mutual interference between components.

[0041] This application also provides a vehicle that includes the frame structure described above, possessing all the technical features and beneficial effects of a frame structure, which will not be elaborated further here.
