Description

Technical Field

[0001] This invention belongs to the field of automotive technology, specifically relating to a front bumper and grille connection device for automobiles and automobiles. Background Technology

[0002] When the front bumper and grille are installed separately on the assembly line, the grille's styling and the assembly rhythm of the assembly line limit the assembly and maintainability requirements. The grille should be easy to install into the front bumper and quick to remove. However, the grille should not come off the front bumper under extreme vehicle operating conditions. Therefore, the two requirements are contradictory and difficult to balance.

[0003] When dealing with these contradictory performance requirements, only reliability can be met. It's impossible to balance the assembly line pace of final assembly and the convenience of after-sales maintenance, as is the case with the current trend of modifying off-road vehicles, which has been widely criticized. Furthermore, it may sacrifice styling; for example, screw or bolt covers need to be cut into the exterior surface for use after the front bumper and grille screws or bolts are connected. These covers conceal the screws or bolts, preventing them from being exposed, which may disrupt the consistency of the design and increase the unit cost of parts, final assembly time, and after-sales maintenance costs. Summary of the Invention

[0004] This invention provides a connecting device for the front bumper and grille of an automobile, which aims to solve the problems in the current assembly of the front bumper and grille of automobiles, which can destroy the consistency of the shape, increase the unit cost of parts, increase the assembly time and after-sales maintenance costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a front bumper and grille connection device for automobiles, comprising a grille assembly and a front bumper assembly; wherein: The grille assembly and the front bumper assembly are non-integrated assembly structures. Several connection structures are provided between the grille assembly and the front bumper assembly, including a first release structure and a second release structure. The first release structure includes a retaining corner on the grille assembly and a retaining hole on the front bumper assembly, with the retaining corner and retaining hole being connected by an adapter; the second release structure includes a claw structure on the grille assembly, a standard part assembled on the claw structure, and a passage retaining hole on the front bumper assembly, with the standard part and passage retaining hole being connected by an adapter; the difference between the first release structure and the second release structure is minimized, and several connection structures can be freely switched and combined by replacing the mold insert and the inspection module.

[0006] In some embodiments, the locking angle adopts a figure-7 shaped locking angle, which is integrally formed into the grille assembly, and the locking hole is a duckbill-type locking hole of the front bumper assembly. The figure-7 shaped locking angle is locked into the inside of the duckbill-type locking hole of the front bumper assembly in the front-to-back assembly direction so as to form a limiting locking engagement.

[0007] In some implementations, the standard part is a type A standard part, which is fixedly assembled on the claw structure. After assembly, the type A standard part and the claw structure assembly are snapped into the passage hole of the front bumper assembly in the front-to-back assembly direction to form a snap-fit.

[0008] In some implementations, the corner and claw structures are two different structures with different shapes, and the card hole and passage card hole are two different hole structures with different hole shapes.

[0009] In some implementations, the total number of connection structures is set to no less than five, and all connection structures are distributed on the mating surfaces of the grille assembly and the front bumper assembly.

[0010] Furthermore, the connection structure adopts a symmetrical arrangement; among them, the two connection structures in the middle position are the first release structures, and the remaining connection structures other than the two middle connection structures are the second release structures.

[0011] Furthermore, the connection structure adopts a symmetrical arrangement; among them, the four connection structures located on the left and right sides are the first release structures, and the remaining connection structures other than the four connection structures on the two sides are the second release structures.

[0012] In some implementations, the mold insert is used to switch the connection structure. The mold insert is a modular structure that is set separately and can be installed in a detachable manner at a preset installation position of the corresponding mold insert.

[0013] In some implementations, the gauge module is used to switch the connection structure. The gauge module is a detachable structure that is set separately. The gauge module is assembled at the preset detection position of the corresponding gauge module to adapt to the size detection of different connection structures.

[0014] The present invention also provides an automobile, including the aforementioned automobile front bumper and grille connecting device.

[0015] The present invention provides a vehicle front bumper and grille connection device, which has at least the following beneficial effects.

[0016] This invention discloses a front bumper and grille connection device for automobiles, comprising several connection structures including a first disengagement structure and a second disengagement structure. By freely switching and combining these two structural combinations, it ensures the reliability requirement that the grille will not detach from the front bumper under extreme vehicle operating conditions, while also considering the assembly line pace and after-sales maintenance convenience, thus meeting current modification trends. The two structural combinations do not sacrifice styling or require cutting screws or bolt caps onto the exterior surface. The freely combinable and switchable structures allow for rapid implementation of solutions to verification issues such as vehicle road testing, shortening the development cycle and saving on tooling costs such as molds and fixtures. Addressing the criticism of easy disassembly and failure in the modification trend, it allows for rapid implementation of solutions while ensuring reliability verification, thus enhancing the automotive brand image. In terms of product design strategy, the holistic design concept extends naturally to mold and fixture design, culminating in physical parts, which shortens the product development cycle and reduces initial investment costs to a certain extent, demonstrating practical significance.

[0026] How to design a front bumper and grille connection scheme that can balance the reliability and assembly maintainability of the connection, without sacrificing styling or causing waste in the development of molds and other tooling, and is suitable for automotive assembly.

[0027] Example 1 like Figures 1-9As shown, the present invention provides a front bumper and grille connection device for automobiles, comprising a grille assembly 100 and a front bumper assembly 200; wherein: The grille assembly 100 and the front bumper assembly 200 are non-integrated assembly structures. Several connecting structures are provided between the grille assembly 100 and the front bumper assembly 200, including a first release structure and a second release structure. The first release structure includes a retaining corner on the grille assembly 100 and a retaining hole on the front bumper assembly 200, with the retaining corner and retaining hole being connected by an adapter; the second release structure includes a claw structure 103 on the grille assembly 100, a standard part assembled on the claw structure 103, and a passage retaining hole 202 on the front bumper assembly 200, with the standard part and passage retaining hole 202 being connected by an adapter; the difference between the first release structure and the second release structure is minimized, and several connection structures can be freely switched and freely combined by replacing the mold insert and the inspection module.

[0028] This invention discloses a front bumper and grille connection device for automobiles. The grille assembly 100 and the front bumper assembly 200 are not integrated into a single assembly structure, which can adapt to the split assembly requirements of the final assembly line and meet the assembly requirements of automobile production. It provides a basic condition for subsequent after-sales maintenance and parts modification. A first release structure and a second release structure are provided between the grille assembly 100 and the front bumper assembly 200. The first release structure is relatively easy to install and remove but difficult to remove, while the second release structure is relatively easy to install and remove and can be removed by twisting. The first and second disengagement structures can improve the problem of the inability to balance connection reliability and assembly maintainability in the prior art. The first disengagement structure, through the matching engagement of the corner and the hole, can ensure that the grille assembly 100 will not detach from the front bumper assembly 200 under extreme operating conditions, meeting the reliability requirements of the vehicle. The second disengagement structure, through the matching engagement of the claw structure 103, standard parts and passage hole 202, can realize the rapid assembly and disassembly of the grille assembly 100 and the front bumper assembly 200, improving the efficiency of final assembly and the convenience of after-sales maintenance. The difference area between the two connection structures is minimized, simplifying the design, reducing structural redundancy, and reducing the difficulty of component production. The connection structure of this invention can be freely switched and combined by replacing the mold insert and the inspection module, which allows the device to adapt to different usage needs, verification scenarios and modification requirements. It does not require the development of a complete set of tooling, saving the development cost of molds and inspection tools, avoiding the waste of tooling resources, and shortening the product development and verification cycle. The snap-fit ​​connection method does not require screws, bolts and plugs on the appearance surface, and will not destroy the consistency and aesthetics of the overall vehicle shape.

[0029] Example 2 In some operating conditions, the locking angle of the automotive front bumper and grille connection device of the present invention adopts a 7-shaped locking angle 102, which is integrally formed on the grille assembly 100, and the locking hole is a front bumper assembly duckbill-type locking hole 201 opened on the front bumper assembly 200; the 7-shaped locking angle 102 is locked into the front bumper assembly duckbill-type locking hole 201 in the front-to-back assembly direction to form a limiting locking fit. This invention defines the first release structure's locking angle as a 7-shaped locking angle 102, which is integrally formed on the grille assembly 100. This improves the structural strength and connection stability of the 7-shaped locking angle 102, preventing problems such as locking angle detachment and breakage. At the same time, the integrally formed structure reduces the number of additional parts, simplifying the production and assembly process. The structural design of the front bumper assembly's duckbill-type locking hole 201 can be adapted to and matched with the 7-shaped locking angle 102. The 7-shaped locking angle 102 is locked from front to back inside the front bumper assembly's duckbill-type locking hole 201, forming a limiting locking fit. This can provide a very strong anti-release constraint effect under the extreme working conditions of the whole vehicle, strengthening the reliability of the connection between the grille assembly 100 and the front bumper assembly 200. The front-to-back assembly direction also conforms to the operation of the automobile assembly line, which can effectively improve the convenience and efficiency of the assembly operation.

[0030] Furthermore, in the automotive front bumper and grille connection device of the present invention, the standard part is a type A standard part 101, which is fixedly assembled on the claw structure 103. After assembly, the type A standard part 101 and the claw structure 103 are assembled together and then snapped into the passage hole 202 of the front bumper assembly 200 in a front-to-back assembly direction to form a snap-fit. The standardized component design of the present invention can reduce the cost of manufacturing, procurement and subsequent replacement, improve the versatility of components, and the fixed assembly of the type A standard part 101 and the claw structure 103 forms a stable assembly, which can ensure compatibility with... Figure 9 The structural stability of the access slot 202 shown in the diagram prevents loosening or displacement after assembly. The assembly method of the assembly being snapped into the access slot 202 from front to back is compatible with the assembly direction requirements of the final assembly line, improving assembly efficiency. At the same time, the snap-fit ​​mechanism allows for easy twisting and unscratching, balancing assembly convenience and disassembly flexibility, and meeting the needs of after-sales rapid repair and off-road vehicle modification.

[0031] In this invention, a connecting device for a car front bumper and grille features two different structural shapes: a locking corner and a locking claw structure 103, and two different hole structures: a locking hole and a passage locking hole 202. This invention avoids confusion and misassembly of the two connecting structures during production and assembly, ensuring that the anti-detachment function of the first detachment structure and the quick-release function of the second detachment structure function independently without interference. Furthermore, the differentiated structural design allows each connecting structure to adapt to its own functional requirements, improving the overall stability and reliability of the connecting device.

[0032] Example 3 In some operating conditions, the total number of connection structures of the automotive front bumper and grille connection device of the present invention is set to no less than five, and all connection structures are distributed in a decentralized manner on the mating surface of the grille assembly 100 and the front bumper assembly 200. The total number of connection structures of the present invention is limited to no less than five, for example, it can be set to ten. The decentralized arrangement of the connection structures can make the connection force between the grille assembly 100 and the front bumper assembly 200 evenly distributed across the entire mating surface, avoiding problems such as excessive stress, component deformation or connection failure due to force concentration in local positions. The decentralized arrangement of ten connection structures can adapt to the structural layout of the front bumper assembly 200 and grille assembly 100 of different models and different shapes, allowing the connection structures at each position to fully play their connection function, improving the stability and safety of the whole vehicle under different driving conditions.

[0033] Furthermore, in the automotive front bumper and grille connection device of the present invention, the connection structure adopts a symmetrical arrangement; wherein, the two connection structures in the middle position are the first disengagement structures, and the remaining connection structures other than the two middle connection structures are the second disengagement structures. The symmetrical arrangement of the present invention ensures that the grille assembly 100 and the front bumper assembly 200 are subjected to balanced forces after assembly, avoiding problems such as loosening, misalignment, or uneven appearance caused by unilateral force offset, thus ensuring the assembly accuracy and appearance coordination of the entire vehicle. The first disengagement structure in the middle position can lock the core area of ​​the grille assembly 100, maximizing the reliability of anti-disengagement under certain working conditions, while the second disengagement structures in the surrounding area can meet the needs of rapid disassembly and assembly over a large area, balancing the reliability of the core position with the ease of disassembly and assembly in the surrounding area.

[0034] Example 4 In some optional operating conditions, the connection structure of the automotive front bumper and grille connection device of the present invention adopts a symmetrical arrangement; wherein, the four connection structures on the left and right sides are the first disengagement structures, and the remaining connection structures other than the four on the sides are the second disengagement structures. The symmetrical layout of the present invention can ensure the stress balance and structural stability of the grille assembly 100 and the front bumper assembly 200 after assembly. The first disengagement structures at the two edge positions can effectively prevent the edge parts of the grille assembly 100 from shaking, lifting or disengaging during vehicle driving and bumping, thus strengthening the connection reliability of the edge area. The second disengagement structure in the middle area facilitates quick disassembly, repair and modification of the core parts of the components. The layout is more suitable for the characteristics of the vehicle structure where the edges are prone to stress and the middle part needs maintenance, thus optimizing the performance of the connection device.

[0035] In some optional operating conditions, the mold insert of the automotive front bumper and grille connection device of the present invention is used to realize the switching of connection structure. The mold insert is a modular structure that is set separately and can be installed in a detachable manner at the preset installation position of the corresponding mold. The present invention uses a separately detachable modular mold insert, which can realize quick disassembly and replacement without redesigning, processing and manufacturing the entire mold, reducing the mold development cost and initial investment. The detachable nature simplifies the operation process of mold adjustment and switching, can quickly adapt to the production needs of two connection structures, shorten product modification time, and the modular design can also improve the versatility and reusability of the mold, avoiding the idleness and waste of mold resources.

[0036] Furthermore, in the automotive front bumper and grille connection device of this invention, a fixture module is used to switch the connection structure. The fixture module is a separately detachable structure, assembled at a preset detection position corresponding to the existing fixture module, for adapting to the dimensional detection of different connection structures. This invention uses a separately detachable fixture module, which can be quickly replaced to adapt to the dimensional detection requirements of two connection structures, eliminating the need to develop multiple independent fixtures for different connection structures, thus reducing fixture development costs. The detachable assembly method improves the efficiency of the inspection operation, quickly completing the dimensional verification of different structures. The fixture module adapts to the inspection needs of the product process, shortening the product verification cycle.

[0037] The present invention also provides an automobile, including a front bumper and grille connection device. By employing the front bumper and grille connection device of the present invention, the reliability and stability of the automobile can be effectively improved.

[0038] Specifically, the automotive front bumper and grille connection device of the present invention includes a grille assembly 100 and a front bumper assembly 200, which are two independent main components constituting the entire device. The grille assembly 100 and the front bumper assembly 200 are non-integrated, separate structures, each with its own independent structural form and assembly attributes. They are not nested or contained within each other, but together as parallel main structures, they constitute the entire automotive front bumper and grille connection device. The assembly and fixation between the grille assembly 100 and the front bumper assembly 200 relies on the connection structure disposed between them. The connection structure is the connecting link between the grille assembly 100 and the front bumper assembly 200. Through the cooperation of the connection structure, the grille assembly 100 and the front bumper assembly 200 can achieve stable and detachable assembly, completing the overall device assembly.

[0039] The connection structure of the present invention includes all the connection and engagement units between the grille assembly 100 and the front bumper assembly 200, including a first release structure and a second release structure with two different functions. The first release structure and the second release structure are combined with each other to form a complete connection structure system.

[0040] The first release structure is a component of the connecting structure, and it consists of mating structures respectively disposed on the grille assembly 100 and the front bumper assembly 200. Specifically, the grille assembly 100 is provided with a 7-shaped locking angle 102 for the first release structure, and the front bumper assembly 200 is provided with a duckbill-shaped locking hole 201 for the first release structure. As a component of the connecting structure, the first release structure can stably connect the grille assembly 100 and the front bumper assembly 200.

[0041] The second disengagement structure is another component of the connecting structure. This second disengagement structure is composed of mating structures respectively disposed on the grille assembly 100 and the front bumper assembly 200. The grille assembly 100 is provided with a claw structure 103 of this structure, on which a type A standard part 101 is mounted. The front bumper assembly 200 is provided with a passage hole 202 for the second disengagement structure. The combination of the claw structure 103 and the type A standard part 101 on the grille assembly 100, mating and engaging with the passage hole 202 on the front bumper assembly 200, together constitute the second disengagement structure, facilitating quick assembly and disassembly between the grille assembly 100 and the front bumper assembly 200.

[0042] Example 5 The structural design concept and method of the automotive front bumper and grille connection device of the present invention specifically include: a first disengagement structure: a 7-shaped clip 102 extends directly from the grille and is assembled from front to back into the duckbill-shaped clip hole 201 of the front bumper assembly; a second disengagement structure: an A-type standard part 101 is assembled on the grille and is assembled from front to back into the passage clip hole 202 of the front bumper assembly.

[0043] The grille structure and front bumper locking hole structure corresponding to the first and second release structures are different. There are no fewer than five connection structures between the grille and the front bumper, and both types of connection structures are arranged simultaneously in all positions to minimize the difference areas. Inserts are used in the difference areas, allowing the mold to achieve both connection structures by replacing the inserts. The difference areas are made into separate modules, allowing for future interchangeability. In the actual parts, the connection structure between the front bumper and the grille can be freely switched and combined between the first and second release structures.

[0044] Specifically, the automotive front bumper and grille connection device of the present invention is designed as follows: Step 1: The connection strategy between the grille assembly 100 and the front bumper assembly 200 includes: the grille assembly 100 and the front bumper assembly 200 are installed on the assembly line separately, rather than being integrated into one assembly line.

[0045] Step Two: In the first disengagement structure, a 7-shaped retaining corner 102 extends directly from the grille assembly 100. It is then assembled from front to back and tapped into the ducktail-style retaining hole 201 of the front bumper assembly. The connection state after assembly is as follows: Figure 5 As shown.

[0046] Step 3: In the second release structure, a claw structure 103 extends from the grille assembly 100, and the type A standard part 101 is assembled. The assembled state is as follows. Figure 8 As shown. Push it into the front bumper assembly access slot 202 from front to back. The connection state after assembly is as follows. Figure 10 As shown.

[0047] Step 4: The structural difference between Step 2 and Step 3 lies in the connection area. The 7-shaped corner 102 and the claw structure 103 of the grille assembly 100 are different. The corresponding front bumper assembly duckbill-type clip 201 and passage clip 202 of the front bumper assembly 200 are also different.

[0048] Step 5: In the data design scheme, the number of connection structures between the grille assembly 100 and the front bumper assembly 200 is set to 10. All connection structures are arranged simultaneously to form a configuration as shown in the figure. Figure 5 The first extraction structure and Figure 10 The second exit structure, the difference region in step four is minimized.

[0049] Step Six: In the mold module design, the areas of difference in Step Four are each separated into individual modules and inlaid into the mold to form mold inserts. The difference in Step Two is achieved by replacing these mold inserts. Figure 5 In the structure and step three Figure 10 The structure.

[0050] Step 7: In the design scheme of the fixture module, the differences in Step 4 are all separated into individual modules and assembled on the fixture. These fixture modules are replaced to correspond to the differences in Step 2 above. Figure 5 In the structure and step three Figure 10 The structure enables the detection of part dimensions.

[0051] Step 8: The actual part structure obtained by replacing and combining the mold inserts in Step 6 can be implemented in the first ejection structure in Step 2. Figure 5 ) and the second extraction structure in step three ( Figure 10 Freely switch and combine between them, such as Figure 11 and Figure 12 These are two typical combination methods. Figure 11 (Symmetrical) Only the two middle structures are the first extraction structures in step two. Figure 5 The remaining structures are the second extraction structures in step three. Figure 12 (Symmetrical) Only the four structures on both sides are the first extraction structures in step two. Figure 5The remaining structure is the second extraction structure described in step three. Based on the actual product structure, the corresponding modules are replaced on the inspection fixture to check the product's dimensions.

[0052] Step Nine: Verification Phase. After reliability road tests and repeated disassembly and assembly verification, the first release structure from Step Two was selected. Figure 5 ) and the second extraction structure in step three ( Figure 10 The optimal combination yields the best connection structure between the grille assembly 100 and the front bumper assembly 200.

[0053] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Anyone skilled in the art can readily implement the present invention according to the description and above. Any modifications, alterations, and variations made based on the technical content disclosed above are equivalent embodiments of the present invention.
