Description

Technical Field

[0001] The utility model relates to the technical field of vehicle body structures, and in particular to a vehicle body frame structure. The utility model also relates to a vehicle provided with the vehicle body frame structure. Background Art

[0002] The body frame refers to the main frame that constitutes the spatial shape of the body. In the existing body frame, a plywood is arranged in the cavity of the side pillar (such as the A-pillar, the B-pillar, and the C-pillar). The plywood can play a role of sound insulation and sealing after foaming. The structure of the side pillar is generally composed of an inner panel and a reinforcement panel. When installing the plywood, it is generally necessary to first set a patch plate on the reinforcement panel to facilitate the fixing of the plywood, and then fix one end of the plywood on the patch plate, and then fix the other end of the plywood on the inner panel. At this time, the plywood is inside the space formed by the inner panel and the reinforcement panel.

[0003] As the requirements for lightweight vehicle design become increasingly stringent, side pillars begin to use extruded profiles to achieve lightweight design. However, the body frame of the extruded profile is an integrated structure. It is impossible to set the plywood at a set position by separately installing the inner panel and the reinforcement panel like the existing side pillars. Although the opening at the end of the extruded profile can be bonded with expansion tape to achieve sealing after expansion, the plywood cannot be installed in the cavity inside the extruded profile. The existing plywood cannot be installed in the cavity of the body frame without destroying the extruded aluminum profile body frame structure. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0040] Embodiment 1

[0041] The present embodiment relates to a vehicle body frame structure, which can achieve sealing of the vehicle body frame structure of an extruded profile and improve the application effect of the frame structure.

[0042] In terms of overall structure, combined Figures 1 to 3 As shown, the vehicle body skeleton structure of this embodiment includes a skeleton body 1 made of extruded profiles, the skeleton body 1 has a cavity t therein, and a plywood 2 is arranged in the cavity t.

[0043] The laminated board 2 includes a frame 201 and a foaming material arranged on the frame 201, and the laminated board 2 is slidably inserted into the cavity t through the opening of the cavity t. After the foaming material is foamed, the laminated board 2 can form a sealed partition for the cavity t.

[0044] At this time, as set above, by sliding the laminated sheet 2 from the opening of the cavity t into the cavity t, and being able to form a sealed partition for the cavity t after foaming, this embodiment can realize the installation of the laminated sheet 2 in the extruded profile body frame, which helps to realize the sealed partition of the specific cavity t in the extruded profile, thereby achieving the purpose of improving the application effect of the body frame.

[0045] Based on the above overall introduction, an exemplary structure of the vehicle body frame structure of this embodiment can be referred to Figures 1 to 3 As shown, at this time, preferably, the skeleton 201 of the laminated board 2 of this embodiment can be set according to the cross-section of the mold cavity t, so that the skeleton 201 can follow the cross-section of the mold cavity t, which can facilitate the laminated board 2 to slide into the mold cavity t, and is also beneficial to ensure the sealing and partitioning effect of the mold cavity t after foaming.

[0046] It is worth mentioning that in this embodiment, as a preferred exemplary form, the cross-sectional shape of the cavity t is a rounded rectangle. Of course, the cross-sectional shape of the cavity t can have a variety of arrangements, and there are generally multiple cavities t in the extruded profile, and the plywood 2 can be arranged in a specific cavity t according to design requirements to form a seal for the vehicle body frame structure.

[0047] Preferably, the skeleton body 1 made of extruded profile in the present embodiment can be made of extruded aluminum profile, for example. Extruded aluminum profile has been widely used in vehicle body skeleton structure. It has good structural strength and is lighter than traditional vehicle body skeletons made of steel, which is beneficial to the weight reduction design of the entire vehicle.

[0048] In addition, as a preferred embodiment, Figure 1As shown, at the end of the sliding insertion stroke, the laminated board 2 in this embodiment is clamped in the cavity t by the clamping structure 3. The clamping structure 3 is provided so that the laminated board 2 can be clamped in the cavity t, which can ensure that the laminated board 2 is stably in the set position in the cavity t, which is beneficial to improving the setting effect of the laminated board 2.

[0049] It should be noted that the sliding insertion stroke of the laminated board 2 refers to the stroke of the laminated board 2 slidingly inserted at the opening of the cavity t until the laminated board 2 is clamped in the cavity t, and the end of the sliding insertion stroke is the predetermined position of the laminated board 2 clamped in the cavity t, and the laminated board 2 needs to be baked after being clamped in the cavity t so that the foaming material can foam and the laminated board 2 can be completely fixed in the cavity t.

[0050] In addition, as a preferred embodiment, refer to Figure 3 , Figure 5 and Figure 6 As shown, the clamping structure 3 in this embodiment includes a clamping joint 301 arranged on the frame 201, and a clamping hole 302 matched with the clamping joint 301 and arranged on the inner wall of the cavity t.

[0051] Specifically, in the present embodiment, the clamping joint 301 is connected to one side of the frame 201 through the elastic connecting arm 303, and in the process of sliding the laminated board 2 into the cavity t, the clamping joint 301 compresses the elastic connecting arm 303, and at the end of the sliding insertion stroke, the elastic connecting arm 303 drives the clamping joint 301 to be clamped into the clamping hole 302. The clamping structure 3 is composed of a matching clamping joint 301 and a clamping hole 302, and the clamping joint 301 is arranged on the frame 201 through the elastic connecting arm 303. The structure is simple, which is conducive to design and manufacturing, and can also ensure that the laminated board 2 can be smoothly slid into the cavity t.

[0052] It is worth mentioning that the material of the card joint 301 and the elastic connecting arm 303 can be nylon, for example, or other plastic materials, as long as they can withstand the foaming temperature of the foaming material, and the use of plastic materials can facilitate the lightweight design of the vehicle.

[0053] Furthermore, as a preferred embodiment, refer to Figure 1 , Figure 5 and Figure 6 As shown, the elastic connecting arm 303 in this embodiment is provided with a deformation groove 304 for the elastic connecting arm 303 to be easily compressed and deformed. The deformation groove 304 is provided on the elastic connecting arm 303 to ensure the deformation effect of the elastic connecting arm 303, thereby ensuring the smoothness of the sliding insertion of the laminated board 2.

[0054] It can be understood that the setting of the deformation groove 304 makes it easy for the elastic connecting arm 303 to be compressed, and when the laminated board 2 is slidably inserted into the cavity t, the elastic connecting arm 303 needs to be compressed first, and at the same time, the elastic connecting arm 303 is always in a compressed state during the sliding insertion stroke of the laminated board 2, until the clamping joint 301 reaches the position of the clamping hole 302, at which time the sliding insertion stroke is at the end, and due to the elastic deformation of the elastic connecting arm 303 itself, the elastic connecting arm 303 pushes the end of the clamping joint 301 to be clamped into the clamping hole 302 to stop the sliding insertion stroke of the laminated board 2.

[0055] In addition, as a preferred embodiment, Figures 1 to 3 As shown, the clamping structures 3 in this embodiment are a group, and the clamping structures 3 are arranged on two opposite sides of the frame 201, which can ensure the reliability of the clamping of the laminated board 2 in the cavity t and help improve the use effect of the laminated board 2.

[0056] It is worth mentioning that in this embodiment, in order to reduce the number of snap-in holes 302 opened on the skeleton body 1, the snap-in structures 3 are arranged in one group. Of course, the snap-in structures 3 can be arranged in one group, two groups, three groups, or four groups, etc., as long as the laminated board 2 can be clamped in the set position inside the cavity t.

[0057] At the same time, as a preferred implementation form, refer to Figure 4 As shown, the snap-in hole 302 in this embodiment is a long hole, and the length direction of the long hole is perpendicular to the sliding direction of the laminated board 2. The snap-in hole 302 is a long hole, which can reduce the difficulty of position matching with the snap-in joint 301 and facilitate the setting of the snap-in hole 302.

[0058] It is understandable that in order to ensure the clamping effect between the clamping connector 301 and the clamping hole 302 , the size ratio of the width to the length of the clamping hole 302 can be, for example, 7:12, so as to ensure that the clamping connector 301 can be smoothly clamped in the clamping hole 302 .

[0059] And, as a preferred implementation form, combined with Figure 3 As shown, the clamping joint 301 in this embodiment is provided with a guiding inclined surface s for guiding the clamping joint 301 to enter the clamping hole 302. The guiding inclined surface s is provided on the clamping joint 301, which can facilitate the clamping joint 301 to enter the clamping hole 302 and ensure the use effect of the clamping structure 3.

[0060] Specifically, the end of the clamping joint 301 has two guiding inclined surfaces s, and the two guiding inclined surfaces s form sharp corners at the end of the clamping joint 301. When the clamping joint 301 is clamped in the clamping hole 302, the sharp corners of the clamping joint 301 are inserted into the clamping hole 302, and the two guiding inclined surfaces s at the end of the clamping joint 301 are squeezed with the inner wall of the clamping hole 302. Under the elastic deformation of the elastic connecting arm 303, the laminated board 2 is stopped at the set position. At this time, the laminated board 2 cannot continue to slide into the inside of the extruded aluminum profile.

[0061] It should be noted that if the size of the card joint 301 is too thick, the sliding insertion process of the laminated board 2 requires a greater force to push the laminated board 2. If the size of the card joint 302 is too thin, the laminated board 2 cannot be stably clamped in the set position. Therefore, in this embodiment, the thickness of the card joint 301 is about 1.5mm-2mm, and the angle α between the guiding inclined surface s of the card joint 301 and its adjacent surface is less than 45° so that the laminated board 2 can be smoothly slid and inserted into the cavity t.

[0062] In addition, as a preferred implementation form, combined with Figures 1 to 3 As shown, a guide structure 4 is provided on the skeleton 201 in this embodiment, and the guide structure 4 is used to guide the sliding of the laminated board 2 in the cavity t. By providing the guide structure 4, the laminated board 2 can be prevented from deflecting during the sliding process, and the smoothness of the sliding of the laminated board 2 can be improved.

[0063] It is understandable that the guide structure 4 can be arranged in the form of a guide plate, a guide column, a guide spherical surface or a guide wheel, etc., which are arranged on the side wall of the frame 201, and it only needs to be able to assist the laminated board 2 to slide smoothly in the cavity t.

[0064] Specifically, as a preferred implementation form, combined with Figures 1 to 3 As shown, the guide structure 4 in this embodiment includes four groups of guide legs 401 arranged on the skeleton 201, and the four groups of guide legs are evenly arranged on the side of the skeleton 201. The material of the guide legs 401 can be nylon, for example. The guide legs 401 are connected to one side of the skeleton 201 and can slide and abut against the inner wall of the cavity t, and the guide legs 401 in each group are arranged on two opposite sides of the skeleton 201. The guide structure 4 uses the guide legs 401 arranged on one side of the skeleton 201, which has a simple structure and is convenient for design and manufacturing.

[0065] During the sliding insertion stroke of the laminated board 2, the ends of the guide legs 401 do not all abut against the inner wall of the cavity t. There is a small gap between some of the guide legs 401 and the inner wall of the cavity t, and the gap is no more than 1 mm, so that the laminated board 2 is not blocked at the entrance to the cavity t, and it is ensured that the laminated board 2 can be pushed smoothly in the cavity t, and it is avoided that the laminated board 2 is deviated sideways during the sliding insertion process and cannot smoothly reach the set position due to the large gap between each leg and the inner wall of the skeleton body 1. When the laminated board 2 is stuck in the set position, the guide legs abut against the inner wall of the cavity t.

[0066] In addition, in the present embodiment, the distance between the end of the guide leg 401 and the bottom surface of the laminated board 2, that is, the length of the guide leg 401 is approximately one-third of the length of the frame 201. Of course, its length can also be less than one-third of the length of the frame 201 or greater than one-third of the length of the frame 201, etc., as long as it can meet the requirement of being able to guide the laminated board 2 to move smoothly in the cavity t.

[0067] It should be noted that, in this embodiment, the skeleton 201, the clamping joint 301 and the guide leg 401 are all made of nylon by one-step injection molding. The integrated setting can ensure the structural stability of the connection between the skeleton 201, the clamping joint 301 and the guide leg 401, and the use of nylon material is conducive to the weight reduction design of the entire vehicle.

[0068] It is worth mentioning that the number of guide legs 401 arranged in this embodiment is four groups. Of course, the number of guide legs 401 arranged can be one group, two groups, three groups, or four groups, etc., as long as it can assist the laminated board 2 to slide smoothly in the cavity t.

[0069] In addition, as a preferred embodiment, Figure 3 As shown, a through hole 202 is provided in the middle of the skeleton 201 in this embodiment, and the foaming material includes a first foaming material 203 arranged around the outer edge of the skeleton 201, and a second foaming material 204 arranged along the edge of the through hole 202. The provision of the through hole 202 is beneficial to reducing the weight of the skeleton 201, and helps to achieve a lightweight design of the laminate 2.

[0070] In this embodiment, the first foaming material 203 and the second foaming material 204 are both made of foaming materials already available in the prior art, such as ethylene-propylene rubber. It should be noted that the foaming temperature of ethylene-propylene rubber is lower than the tolerance temperature of nylon. Therefore, during the baking and foaming process of ethylene-propylene rubber, the structure of the skeleton 201, the clamping joint 301 and the guide leg 401 will not be affected by the baking temperature and cause structural damage.

[0071] It can be understood that when the laminated board 2 in this embodiment is installed, the clamping joint 301 is first compressed, and then the laminated board 2 is pushed into the cavity t by hand or by holding a tube-shaped tool. During the sliding insertion stroke of the laminated board 2, the clamping joint 301 and the guide leg 401 assist the insertion process of the laminated board 2. The clamping joint 301 is clamped in the clamping hole 302 at the end of the sliding stroke, and the end of the clamping joint 301 is inserted into the clamping hole 302. Due to the elastic deformation of the elastic connecting arm 303 itself, the laminated board 2 can stop at the set position. After that, the foaming material expands after baking, fixes the laminated board 2 at the set position and blocks the cavity t, thereby realizing the sealing and isolation of the specific cavity t.

[0072] The vehicle body frame structure of the present embodiment adopts the above design, by making the laminated sheet 2 slide and insert into the cavity t from the opening of the cavity t, and can form a sealed partition for the cavity t after foaming, so that the laminated sheet 2 can be installed in the extruded aluminum profile vehicle body frame, which helps to achieve the sealed partition of the specific cavity t in the extruded aluminum profile, can improve the application effect of the extruded aluminum profile frame structure, and has good practicality.

[0073] Embodiment 2

[0074] This embodiment relates to a vehicle, in which the vehicle body frame structure in the first embodiment is provided.

[0075] The vehicle of this embodiment adopts the body frame structure in the first embodiment, so that when the frame body 1 is made of extruded profile, the plywood 2 can be used to achieve sealing partition at the position where partition is required in the cavity t of the frame body 1, which helps to improve the waterproof sealing and sound insulation and noise reduction effect of the whole vehicle, and has good practicality.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
