Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically, to a front-end frame device and a vehicle. Background Technology

[0002] In the field of automotive design and manufacturing, the front-end frame, as a crucial structural component of the engine compartment, must not only ensure the strength and safety of the vehicle's front end but also accommodate the opening and closing mechanism of the hood. Traditionally, this involves adding extra protruding structures to the front-end frame to provide mounting points for the hood support struts. However, this design approach not only increases manufacturing costs and weight but can also compromise the clean appearance of the engine compartment, especially when the hood is open, as the exposed mounting structures directly affect the secondary appearance of the front of the vehicle. In existing technologies, the struts supporting the hood often require specially designed brackets or fixing points. The design and manufacture of these fixing points not only increase the complexity of the vehicle body but may also, in some cases, limit the available space in the engine compartment, impacting the layout of the engine and related components. Utility Model Content

[0003] The main objective of this invention is to provide a front-end frame device and vehicle to solve the problem that the front-end frame in the prior art requires an additional complex structure as the mounting point for the hood support rod, which increases the manufacturing cost and weight of the vehicle.

[0004] To achieve the above objectives, according to one aspect of the present invention, a front-end frame device is provided. The front-end frame device includes: a front-end frame, on which a mounting structure is provided; a bushing, a portion of which is disposed within the mounting structure, the bushing being for a support rod to pass through, wherein one end of the support rod is used to connect to the front-end frame, and the other end of the support rod is used to connect to the engine hood.

[0005] Furthermore, the outer ring of the bushing has a groove structure, and part of the front end frame extends into the groove structure to engage with the bushing.

[0006] Furthermore, at least part of the bushing is located inside the mounting structure, while another part of the bushing is located outside the mounting structure and abuts against the front frame.

[0007] Furthermore, the bushing includes: a first segment, which is located outside the mounting structure and abuts against the outer wall of the front frame; a second segment, which is connected to the first segment, and the outer wall of the second segment is connected to the inner wall of the mounting structure; and a third segment, which is connected to the second segment, which is located outside the mounting structure and abuts against the outer wall of the front frame. The first segment, the second segment, and the third segment are connected in a continuous manner, and the outer rings of the first segment, the second segment, and the third segment form a groove structure.

[0008] Furthermore, the outer diameter of the first segment is set to gradually increase in the direction toward the second segment.

[0009] Furthermore, the maximum outer diameter of the first segment is D1, the outer diameter of the second segment is D2, the outer diameter of the third segment is D3, the diameter of the mounting structure is D4, and the inner diameter of the bushing is D5, wherein 18.8mm≤D1≤19.2mm, and / or 15.8mm≤D2≤16.2mm, and / or 29.8mm≤D3≤30.2mm, and / or 16.65mm≤D4≤16.75mm, and / or 7.8mm≤D5≤8.2mm.

[0010] Furthermore, the height of the first segment is h1, the height of the second segment is h2, the height of the third segment is h3, and the height of the installation structure is h4, wherein 5.8mm≤h1≤6.2mm, and / or 3.8mm≤h2=h4≤4.2mm, and / or 4.8mm≤h3≤5.2mm.

[0011] Furthermore, the first, second, and third sections are designed as a single integrated unit.

[0012] Furthermore, the first segment is a columnar structure. Along the axial direction of the first segment, the angle formed by one of the tangents on the outer surface of the first segment and the extension of the axial line of the first segment is α / 2, where 39.5°≤α≤40.5°, and the direction of the tangent is the same as the inclination direction of the outer surface of the first segment.

[0013] According to another aspect of the present invention, a vehicle is provided, the vehicle including a front-end frame device, the front-end frame device being the front-end frame device of the above embodiment.

[0014] By applying the technical solution of this utility model, an installation structure is set on the front frame, and part of the bushing is embedded in the installation structure, so that the support rod can be stably passed through the bushing and connected to the front frame and the engine hood. This avoids the traditional practice of adding a complex structure to the front frame to fix the support rod, reduces the use of materials, and lowers production costs. In addition, since part of the bushing is located inside the installation structure, the connection point between the support rod and the front frame is not easily observed after the engine hood is opened, thus achieving structural optimization. This solves the technical problems of increased manufacturing costs, vehicle weight, and impact on the quality of secondary appearance caused by the need for additional structures in the traditional engine hood support rod installation method.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0031] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0032] Combination Figures 1 to 7 As shown, according to a specific embodiment of the present invention, a front-end frame device is provided.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, the front frame device includes: a front frame 10, on which a mounting structure is provided; a bushing 20, a portion of which is disposed within the mounting structure, the bushing 20 being used for a support rod 30 to pass through, wherein one end of the support rod 30 is used to connect to the front frame 10, and the other end of the support rod 30 is used to connect to the engine hood.

[0034] In this embodiment, by setting an installation structure on the front frame 10 and embedding part of the bushing 20 into the installation structure, the support rod 30 can be stably passed through the bushing 20 and connected to the front frame 10 and the engine hood. This avoids the traditional practice of adding a complex structure to the front frame 10 to fix the support rod 30, reduces material usage, and lowers production costs. In addition, since part of the bushing 20 is located inside the installation structure, the connection point between the support rod 30 and the front frame 10 is not easily observed after the engine hood is opened, thus achieving structural optimization. This solves the technical problems of increased manufacturing costs, vehicle weight, and impact on the secondary appearance finish caused by the need for additional structures in the traditional engine hood support rod installation method.

[0035] Furthermore, the outer ring of the bushing 20 has a groove structure, and part of the front end frame 10 extends into the groove structure to engage with the bushing 20.

[0036] Specifically, the groove structure allows the bushing 20 to be securely fixed to the front frame 10, improving the stability of the connection between the support rod 30 and the front frame 10 and ensuring structural safety and reliability during the opening and closing of the engine hood. Furthermore, this snap-fit ​​method simplifies the bushing installation process, eliminating the need for additional fasteners such as screws or adhesives, making the assembly process faster, reducing assembly difficulty and time costs, and improving production efficiency.

[0037] Furthermore, at least a portion of the bushing 20 is located within the mounting structure, while another portion of the bushing 20 is located outside the mounting structure and abuts against the front frame 10.

[0038] Specifically, the inner and outer split design of the bushing 20 makes the connection between the bushing and the front frame more secure, enhances the stability of the support rod during rotation, and reduces the problem of unstable opening of the hood caused by the swaying or displacement of the support rod.

[0039] like Figure 3 As shown, the bushing 20 includes: a first segment 21, which is located outside the mounting structure and abuts against the outer wall of the front frame 10; a second segment 22, which is connected to the first segment 21, and the outer wall of the second segment 22 is connected to the inner wall of the mounting structure; and a third segment 23, which is connected to the second segment 22, which is located outside the mounting structure and abuts against the outer wall of the front frame 10. The first segment 21, the second segment 22, and the third segment 23 are connected in a continuous manner, and the outer rings of the first segment 21, the second segment, and the third segment form a groove structure.

[0040] Specifically, the first segment 21 and the third segment 23 are located outside the front frame 10 and abut against it, while the second segment 22 is located inside the mounting structure. Through the abutment of the first segment 21 against the outer wall of the front frame 10, and the further abutment of the third segment 23 against the outer wall of the front frame 10, the bushing 20 and the front frame 10 form a double physical contact. This significantly enhances the connection strength between the bushing 20 and the front frame 10, ensuring the stability of the support rod 30 during use and reducing the safety risks caused by structural loosening or failure. The segmented design of the bushing 20, especially through the connection of the second segment 22 with the inner wall of the mounting structure, can more effectively disperse the stress transmitted from the support rod 30 to the front frame, avoiding stress concentration, improving the durability of the bushing 20 and the front frame 10, and extending their service life.

[0041] In this embodiment, the mounting structure is a mounting hole; in other embodiments, it can also be set as a groove structure.

[0042] Furthermore, the outer diameter of the first segment 21 is set to gradually increase in the direction toward the second segment 22.

[0043] Specifically, the gradually increasing outer diameter design creates a progressively larger contact surface between the first segment 21 and the front frame 10. This design increases the contact area, thereby improving friction. During the use of the support rod 30, friction helps improve the stability and support of the bushing 20, preventing the support rod 30 from shaking or falling off during rotation or under stress.

[0044] like Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, the maximum outer diameter of the first segment 21 is D1, the outer diameter of the second segment 22 is D2, the outer diameter of the third segment 23 is D3, the diameter of the mounting structure is D4, and the inner diameter of the bushing 20 is D5. Among these, 18.8mm≤D1≤19.2mm, and / or, 15.8mm≤D2≤16.2mm, and / or, 29.8mm≤D3≤30.2mm, and / or, 16.65mm≤D4≤16.75mm, and / or, 7.8mm≤D5≤8.2mm.

[0045] Specifically, the maximum outer diameter of the first segment 21 is the outer diameter at the point where it abuts against the front frame 10, increasing the contact area. The outer diameter of the third segment 23 is significantly larger than the maximum outer diameter of the first segment 21. The larger outer diameter of the third segment 23 provides a wider outer contact surface, which helps improve the stability and load-bearing capacity between the bushing 20 and the front frame 10 when the support rod 30 rotates, ensuring the support rod 30 is firmly supported during use and reducing the risk of bushing 20 displacement due to external forces or vibrations. The diameter of the mounting structure is slightly larger than the outer diameter of the second segment 22, making it easier to position and insert the bushing 20 into the mounting hole of the front frame 10, reducing assembly difficulty and time, and improving production efficiency.

[0046] In one embodiment, D1 is 19mm, D2 is 16mm, D3 is 30mm, D4 is 16.7mm, and D5 is 8mm.

[0047] like Figure 5 As shown, the height of the first segment 21 is h1, the height of the second segment 22 is h2, the height of the third segment 23 is h3, and the height of the installation structure is h4. Among these, 5.8mm≤h1≤6.2mm, and / or 3.8mm≤h2=h4≤4.2mm, and / or 4.8mm≤h3≤5.2mm.

[0048] In one embodiment, h2 = h4 = 4 mm, so that the second segment 22 can be fully matched with the mounting structure in the axial direction, thereby enhancing the stability and support of the bushing 20 and preventing the support rod 30 from shaking or falling off when rotating or under force.

[0049] In another embodiment, h1 is set to 6 mm, and / or h3 is set to 5 mm.

[0050] Furthermore, the first segment 21, the second segment 22, and the third segment 23 are integrally molded.

[0051] Specifically, the one-piece bushing structure eliminates the connection gaps between different sections, reduces potential failure points caused by wear or loosening at the connection, improves the overall strength and service life of the bushing, and ensures the stability and safety of the hood support rod under various operating conditions.

[0052] Furthermore, the first segment 21 is a columnar structure. Along the axial direction of the first segment 21, the angle formed by one of the tangents on the outer surface of the first segment 21 and the extension of the axial direction of the first segment 21 is α / 2, where 39.5°≤α≤40.5°, and the direction of the tangent is the same as the tilt direction of the outer surface of the first segment 21. The defined tilt angle α / 2 helps to achieve rapid positioning and insertion during assembly, reduces assembly errors, and simplifies the assembly process.

[0053] In one embodiment, α is 40°.

[0054] Among them, bushing 20 is made of rubber material.

[0055] According to another aspect of the present invention, a vehicle is provided, the vehicle including a front-end frame device, the front-end frame structure being the front-end frame device of the above embodiment.

[0056] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0057] (1) By using rubber bushings to connect the headgear support rod to the front frame, the additional exposed structure is omitted, reducing material and production costs.

[0058] (2) The tangent inclination angle of the first segment 21 and the difference in outer diameter between the second segment 22 and the third segment 23 ensure a firm connection between the bushing and the front frame, and improve the stability of the hair cover support rod during rotation and support.

[0059] (3) The tight fit between the bushing and the front frame optimizes the sealing effect, prevents external dust and moisture from entering the engine compartment, and protects internal components from corrosion and wear.

[0060] (4) The installation and concealment method of the bushing improves the appearance of the front frame, making it more refined and smooth, and enhancing the overall aesthetics of the vehicle and the integrity of the secondary appearance.

[0061] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
