Description

Technical Field

[0001] The utility model relates to the field of automobiles, in particular to a front engine compartment cover and a vehicle body structure of an automobile. Background Art

[0002] The front bonnet of a car is an important part of the car's styling. The matching effect between the front bonnet and other surrounding parts directly affects the quality of the entire car. When assembling the car, it is necessary to use complex tooling and processes to ensure that the front bonnet is assembled in a reasonable position. This ensures that the front bonnet and other surrounding parts meet the specified clearance and surface difference requirements, ultimately improving the appearance quality of the entire vehicle.

[0003] Figure 1 The figure shows the installation structure diagram of the front engine cover of the car in the related art. Please refer to Figure 1 In the related art, the front bonnet 1′ of the automobile adopts the technical route of positioning with tooling 2′, transportation with auxiliary tools, manual assembly, and repeated adjustment to realize the fixed assembly of the front bonnet 1′. Figure 1 The front bonnet 1' of the installation method shown in the figure requires positioning tooling 2', lifting aids and multiple assembly adjustment stations for each vehicle type. If the production line assembles multiple vehicle types, such as different shapes or vehicle sizes, the tooling, aids and auxiliary assembly parts cannot be shared and need to be adjusted accordingly.

[0004] When the body shop assembles the front bonnet 1′, it first uses the tooling 2′ to position it on the body at the fenders on both sides to ensure the front and rear position of the front bonnet 1′. The front bonnet 1′ is then transported to the top of the tooling 2′ using a lifting aid. When the aid falls, ensure that the two positioning holes on the front bonnet 1′ fall on the positioning pins of the tooling. The front bonnet 1′ is then screwed and fixed to the hinges that have been fixed to the body in advance. After the bolts are fixed, the tooling and aids are removed and transported back to the previous assembly station. The on-site operator then uses the tooling to close the front bonnet to the locked position, check the gap and surface difference between the front bonnet and surrounding parts, and make assembly adjustments to ensure that the requirements of the vehicle are met. The entire process requires one to two people to work synchronously at each station. Utility Model Content

[0043] The following is a detailed description of a car front hood and body structure provided by the present application in conjunction with the drawings in the specification of the present application.

[0044] Figure 2 The figure shows a schematic diagram of the structure of a front engine cover of a car provided in an embodiment of the present application. Figure 2 ,like Figure 2 As shown, the automobile front bonnet provided in the present application includes a front bonnet body 1 and a sliding component, wherein the sliding component is arranged on the inner side of the front bonnet body 1; the sliding component includes at least a first sliding component 211 and a second sliding component 221; along a first direction, the first sliding component 211 and the second sliding component 221 are located at different positions of the front bonnet body 1; the first direction is the length direction of the vehicle body.

[0045] Figure 3 FIG. 1 is a schematic diagram of a structure of a vehicle body structure provided by an embodiment of the present application in the initial stage of sliding cooperation (the front engine cover body 1 is omitted in the figure, and only the slider 2111 set on the inner side of the front engine cover body 1 and the structure of the slideway 2112 set on the front engine compartment are shown). Figure 2 and Figure 3The present application improves the structure of the existing automobile front bonnet by arranging a sliding component on the inner side of the front bonnet body 1. Thus, when the front bonnet and the front cabin are assembled, the sliding component on the front bonnet can match the sliding component at the corresponding position on the front cabin, so that the front bonnet can adjust its relative position with the front cabin in the first direction by relying on its own sliding component, thereby playing a role in adjusting the gap between the front bonnet and the surrounding parts in the first direction. In this process, tooling positioning, auxiliary tool transportation and other processes as well as tooling and auxiliary tools used in related processes are saved, which greatly reduces the complexity of the installation process and improves the device efficiency.

[0046] It can be understood that in the present application, the sliding components arranged on the inner side of the front bonnet body 1 include at least a first sliding component 211 and a second sliding component 221, and along the length direction of the vehicle body, the first sliding component 211 and the second sliding component 221 are located at different positions of the front bonnet body 1; specifically, the front bonnet body 1 has a certain mass and a certain length in the first direction. The present application arranges sliding components at different front and rear positions on the inner side of the front bonnet body 1 to help improve the stability of the front bonnet body 1 when it cooperates with the front cabin, which is convenient for assembly.

[0047] It is understandable that if the sliding component is only arranged at the front end of the front bonnet body 1 or only arranged at the rear end of the front bonnet body 1, then during assembly, the front bonnet body 1 will be unbalanced front to back, and the end without the sliding component installed needs to be manually lifted up for smooth installation; in some embodiments of the present application, by arranging sliding components at a position close to the front end and a position close to the rear end of the front bonnet body 1, during installation, the front part of the bonnet and the rear part of the bonnet can be slidably connected to the front cabin at the same time, which is more labor-saving and reduces labor.

[0048] It can be understood that in some other embodiments of the present application, the sliding component on the inner side of the front bonnet body 1 may also include a third sliding component, etc. The first sliding component 211, the second sliding component 221, and the third sliding component are arranged in sequence along the first direction.

[0049] Please continue to refer to Figure 2 In some embodiments of the present application, along the second direction, the first sliding component 211 and / or the second sliding component 221 at least includes a left sliding component and a right sliding component, and the second direction is the width direction of the vehicle body.

[0050] Specifically, the front bonnet body 1 has a certain mass and a certain width in the second direction. The first sliding component 211 and / or the second sliding component 221 at least include a left sliding component and a right sliding component. In this way, in the width direction of the vehicle body, when the front bonnet body 1 is slidingly connected to the front cabin, the sliding process of the front bonnet body 1 is more stable, which is conducive to the installation of the front bonnet.

[0051] It can be understood that, in some embodiments of the present application, the first sliding component 211 includes a left sliding component and a right sliding component, and the second sliding component 221 also includes a left sliding component and a right sliding component.

[0052] In some other embodiments of the present application, the first sliding component 211 includes a left sliding component and a right sliding component; the second sliding component 221 includes only a middle sliding component; along the second direction, the middle sliding component is located between the left sliding component and the right sliding component.

[0053] In some other embodiments of the present application, the second sliding component 221 includes a left sliding component and a right sliding component; the first sliding component 211 only includes a middle sliding component; along the second direction, the middle sliding component is located between the left sliding component and the right sliding component.

[0054] In some embodiments of the present application, the left sliding component and the right sliding component included in the first sliding component 211 and / or the second sliding component 221 are symmetrically arranged about the central axis of the second direction of the front engine cover body 1, so that the sliding connection process is more stable when the front engine cover body 1 is installed.

[0055] Please continue to refer to Figure 2 In some embodiments of the present application, along the first direction, the first sliding component 211 and / or the second sliding component 221 is a slider 2111; and / or the first sliding component 211 and / or the second sliding component 221 is a slideway 2112.

[0056] Specifically, as an embodiment of the present application, the sliding component arranged on the inner side of the front engine cover body 1 can be a slider 2111, so that a corresponding slide 2112 can be arranged at the corresponding position of the front engine cabin; the sliding component arranged on the inner side of the front engine cover body 1 can also be a slide 2112, then a corresponding slider 2111 is arranged at the corresponding position of the front engine cabin.

[0057] Figure 4 and Figure 5 FIG. 1 is a schematic diagram showing two states of the vehicle body structure provided by an embodiment of the present application during the sliding fit process. Figure 6 The figure shows a structural schematic diagram of the vehicle body structure provided by the embodiment of the present application after the sliding fit is completed; Figure 4 , Figure 5 and Figure 6 The front engine cover body 1 is omitted, and only the slider 2111 on the inner side of the front engine cover body 1 and the structure of the slideway 2112 provided at the front engine room are shown.

[0058] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 Based on the same inventive concept, the present application also provides a vehicle body structure, including a front engine cover body 1, a front engine compartment and a sliding assembly, wherein the sliding assembly includes at least a first sliding structure 21 and a second sliding structure 22; along a first direction, the first sliding structure 21 and the second sliding structure 22 are located at different positions of the vehicle body; the first direction is the length direction of the vehicle body; the front engine cover body 1 is slidably connected to the front engine compartment through the first sliding structure 21 and the second sliding structure 22.

[0059] Specifically, please combine Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The vehicle body structure of the present application includes a front bonnet body 1 and a front cabin, and the front bonnet body 1 and the front cabin are slidably connected via a sliding assembly. During the slidable connection between the front bonnet body 1 and the front cabin, the sliding distance and the sliding direction can be controlled to ensure that the front bonnet of the automobile has a suitable gap with the surrounding parts.

[0060] Please Figure 1 and Figure 3 , Figure 4 , Figure 5 and Figure 6 The structures shown are compared.

[0061] exist Figure 1 In the structure shown, when installing the front hood of the car, first use one to three sets of tooling to position it on the body at the fenders 5 on both sides to ensure the front and rear and left and right positions of the front hood; then use the lifting aid to transport the front hood to the top of the tooling, and when the aid falls, ensure that the two positioning holes on the front hood fall on the positioning pins of the tooling; then screw the front hood to the hinges fixed to the body in advance. After fixing the bolts, remove the tooling and the aids and transport them back to the previous assembly station. The on-site operator then uses the tooling to close the front hood to the locked position, check the gap and surface difference between the front hood and the surrounding parts, and make assembly adjustments to ensure that the requirements of the vehicle are met. The entire process requires one to two people to work synchronously at each station.

[0062] Please refer to Figure 2 The front bonnet body 1 and the front nacelle in the vehicle body structure of the present application are installed in the same manner as Figure 1Different installation structures, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 When assembling the front hood body 1 of the present application with the vehicle body structure, there is no need to install tooling, disassemble tooling, or transport the front hood to the top of the tooling by hoisting. The front hood body 1 can be slid to a suitable position in the front hood directly by relative sliding with the front hood to meet the matching clearance between the front hood of the car and the surrounding parts, and then fixedly connected. Figure 1 Compared with the structure shown, this application has the following advantages:

[0063] First: the vehicle body structure of the present application achieves the specified clearance and face difference requirements between the front bonnet body 1 and other surrounding parts through the sliding cooperation between the front bonnet body 1 and the front bonnet; the front bonnet of the automobile does not require tooling, lifting tools and auxiliary parts during the installation process, and can adapt to the needs of different production lines, greatly improving the versatility;

[0064] Second: In the present application, the installation process of the front engine cover body 1 and the front engine compartment is simple and convenient, saving a lot of operation hours;

[0065] third: Figure 1 The front engine cover installation method shown requires one to two people to operate at each station. The front engine cover with sliding fit can be completed at one station, and the corresponding labor requirements can be reduced after the number of stations is reduced.

[0066] Please combine Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments of the present application, along the second direction, the first sliding structure 21 and / or the second sliding structure 22 at least include left sliding structures 21A, 22A and right sliding structures 21B, 22B; the second direction is the width direction of the vehicle body.

[0067] Specifically, based on reasons similar to those mentioned above, the front engine cover body 1 of the present application has a certain mass and a certain width in the second direction. The first sliding structure 21 includes a left sliding structure 21A and a right sliding structure 21B, and the second sliding structure 22 includes a left sliding structure 22A and a right sliding structure 22B. In this way, when the front engine cover body 1 is slidably connected to the front engine room through the first sliding structure 21 and the second sliding structure 22, the sliding process of the front engine cover body 1 is more stable, which is conducive to the installation of the front engine cover.

[0068] Please combine Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments of the present application, the left sliding structure 21A, 22A and the right sliding structure 21B, 22B all include a slider 2111 and a slide 2112 cooperating with the slider 2111, one of the slider 2111 and the slide 2112 is arranged on the inner side of the front engine compartment cover body 1, and the other of the slider 2111 and the slide 2112 is arranged in the front engine compartment.

[0069] Please combine Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments of the present application, the slide 2112 is disposed at the front cabin.

[0070] Specifically, as mentioned above, the slide 2112 can be located on the inner side of the front engine cover body 1, or can be set in the front engine compartment, with no functional difference; but as a preference, the slide 2112 can be set in the front engine compartment, which is easier to manufacture from the perspective of parts molding.

[0071] It should be noted that the structure and inclination angle of the slide 2112 need to be set according to the front engine cover assembly path to meet the clearance requirements between the front engine cover and surrounding parts.

[0072] Figure 7 Shown is a structural schematic diagram of another vehicle body structure provided by an embodiment of the present application at an initial stage of sliding fit; Figure 8 Shown Figure 7 A schematic diagram of the structure of the vehicle body shown after the sliding fit is completed; Figure 7 and Figure 8 The front engine cover body 1 is omitted, and only the slider 2111 set on the inner side of the front engine cover body 1 and the structure of the slideway 2112 set at the front engine room are shown.

[0073] Please refer to Figures 3 to 8 In some embodiments of the present application, a first limiting structure 3 is provided at one end of the slideway 2112 along the first direction.

[0074] Specifically, in order to facilitate the processing and manufacturing of the sliding assembly, the slide 2112 is set at the front cabin; in the present application, the front cabin cover body 1 and the front cabin are slid relative to each other to achieve the adjustment of the spacing between the front cabin cover body 1 and the surrounding parts at the front cabin; the limiting structure set at one end of the slide 2112 plays an indication and limiting role when the front cabin cover body 1 and the front cabin are initially matched, so that the front cabin cover body 1 can be installed and disassembled at the predetermined slide 2112 position; Figures 3 to 8As shown, in the initial stage of installation of the front engine cover main body 1, the sliding part of the front engine cover can be located on one side of the first limiting structure 3. During the installation process, it slides along the slide 2112 until it reaches the expected position. In this process, the first limiting structure 3 has an indicating role for the initial placement position of the front engine cover; in addition, during the disassembly process of the front engine cover, the front engine cover main body 1 slides along the slide 2112 in the direction opposite to the installation direction, and the first limiting structure 3 can play a limiting role, which is convenient for disassembly.

[0075] Please refer to Figures 3 to 8 In some embodiments of the present application, a second limiting structure 4 is provided on one side of the slideway 2112 along the second direction.

[0076] It can be understood that, during the installation process of the front engine cover body 1, it is not only desired that the front engine cover body 1 and the parts at the front engine cabin have a reasonable gap in the first direction, but it is also desired that the front engine cover body 1 and the parts at the front engine cabin have a reasonable gap in the second direction; based on this, a second limiting structure 4 is provided on one side of the slide 2112, and the second limiting structure 4 can prevent the front engine cover body 1 from deviating in the second direction, so that after the front engine cover body 1 is matched with the front engine cabin, the corresponding gap requirement can also be met in the second direction.

[0077] Please continue to refer to Figures 3 to 8 In some embodiments of the present application, the slide 2112 is disposed at the fender 5 of the front engine compartment; the slide 2112 is integrally disposed with the fender 5 or is fixed on the fender 5 .

[0078] Specifically, the fender 5 is a vehicle body outer panel that covers the wheels and is disposed above the wheels of the vehicle as an outer panel on the side of the vehicle. Figure 3 The parts marked with numbers 51, 52, and 53 are all components of the fender 5; in the present application, in order to facilitate the setting of the slide 2112, the slide 2112 is set at the fender 5; it can be understood that the slide 2112 and the fender 5 can be integrally formed of plastic, and the slide 2112 can also be set separately.

[0079] like Figures 3 to 6 The structure shown is an example of an integrated arrangement of the slideway 2112 and the fender 5; Figure 7 , Figure 8 The structure shown is an example in which the slideway 2112 is separately provided at the fender 5 .

[0080] Please continue to refer to Figures 3 to 8 In some embodiments of the present application, along the third direction, the slideway 2112 is higher than the fender 5;

[0081] After the front bonnet body 1 is installed in coordination with the front nacelle, the slider 2111 is located above the fender 5, and there is a gap between the slider 2111 and the fender, the shortest distance of the gap is 3 mm, and the third direction is the height direction of the vehicle body.

[0082] For more details, please refer to Figure 3 and Figure 8 ,exist Figures 3 to 8 In the embodiment, the front engine cover body 1 and the front engine compartment rely on the sliding assembly located between the front engine cover body 1 and the front engine compartment to realize the position adjustment of the front engine cover body 1; after the position is adjusted, the front engine cover body 1 needs to be fixedly connected to the front engine compartment by fasteners such as screws; Figure 3 and Figure 8 As shown, after the position is adjusted, the slider 2111 is located above the fender 5, and there is a gap between the slider 2111 and the fender 5. In this way, in the height direction, the slider 2111 will not interfere with the subsequent fixation of the front hood body 1, and the gap between the slider 2111 and the fender 5 is equivalent to the tolerance distance in the height direction.

[0083] Please combine Figure 2 and Figure 3 or Figure 2 and Figure 8 In some embodiments of the present application, along the first direction, the slideway 2112 of the first sliding structure 21 is located at the rear of the front nacelle relative to the slideway 2112 of the second sliding structure 22;

[0084] Along the first direction, in the first sliding structure 21 and the second sliding structure 22, the slideway 2112 is sloped, and one end of the slideway 2112 close to the front of the front cabin is higher than one end of the slideway 2112 close to the rear of the front cabin;

[0085] Along the first direction, the height of the slideway 2112 in the second sliding structure 22 is higher than the height of the slideway 2112 in the first sliding structure 21.

[0086] like Figure 3 and Figure 8 As shown, when the height of the slide 2112 in the second sliding structure 22 is higher than the height of the slide 2112 in the first sliding structure 21, and the end of the slide 2112 close to the front of the front cabin is higher than the end of the slide 2112 close to the rear of the front cabin, when the front cabin cover body 1 is installed, the initial placement position can be located at the end of the slide 2112 close to the front of the front cabin. In this way, it is only necessary to slide the front cabin cover down along the ramp-shaped slide 2112 toward the rear of the front cabin, which is more labor-saving.

[0087] In addition, in some embodiments of the present application, considering the shape and installation of the automobile front bonnet itself, the inclination angle α of the slide 2112 in the second sliding structure 22 can be greater than the inclination angle α of the slide 2112 in the first sliding structure 21. In this way, the front bonnet has a certain rotation tendency during installation, which is convenient for installation.

[0088] It should be additionally explained here that the inclination angle α of the slide 2112 is determined according to the shape and installation requirements of the front engine hood of the automobile. In some cases, the slide 2112 can also be flat without an inclination angle.

[0089] It should also be noted that the slidingly matched front engine cover of the automobile described in the present application realizes its function by means of a slider 2111 and a slideway 2112. The slideway 2112 structure is not limited to the fender 5, but can also be arranged on the vehicle body, interior and exterior parts; it is only necessary to provide a corresponding slider 2111 at the corresponding position of the front engine cover of the automobile.

[0090] Finally, please refer to Figures 2 to 8 In some embodiments of the present application, the assembly process of the front engine compartment cover of the automobile is as follows:

[0091] In the final assembly workshop, the on-site operator moves the front hood to the upper part of the vehicle body, aligns it with the first limiting structure 3 in the sliding assembly and naturally drops it. At this time, the slider 2111 on the front hood body 1 falls on the slide 2112 on the fender 5. After the front hood falls, the front hood is pushed backward along the vehicle body. At this time, the slider 2111 of the front hood slides along the slide 2112 structure. The inclination angle α of the slide 2112 is calculated based on the assembly path of the front hood to ensure that the front hood maintains a reasonable gap with the surrounding parts when sliding. After the front hood slides to the assembly position, it relies on the positioning assembly ( Figures 3 to 8 The second limiting structure 4 in the positioning assembly is part of the positioning assembly) to complete the preliminary positioning. After the on-site operator adjusts the gap and the surface difference, the front engine cover is fastened to the vehicle body with bolts to complete the entire assembly process.
