[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] Reference below Figure 1-Figure 3 A vehicle frame 100 according to an embodiment of the present invention will be described. The vehicle frame 100 may be applied to a vehicle.

[0029] Combine Figure 1-Figure 3 As shown, the vehicle frame 100 according to the present invention can mainly include: a floor 10 and a door sill beam 20, wherein the door sill beam 20 is arranged on at least one side of the floor 10 in the left and right directions, one of the floor 10 and the door sill beam 20 is provided with a first plug-in portion 21, and the other is provided with a second plug-in portion 11, the first plug-in portion 21 and the second plug-in portion 11 are plug-fitted, and adhesive is provided between the first plug-in portion 21 and the second plug-in portion 11.

[0030] Specifically, arranging the sill beam 20 on at least one side of the floor 10 in the left-right direction can not only increase the structural strength of the frame 100 , but also absorb energy when the frame 100 collides, and also provide convenience for the installation of the door.

[0031] Furthermore, by providing a first plug-in portion 21 on one of the door sill beam 20 and the floor 10 and providing a second plug-in portion 11 on the other, after the first plug-in portion 21 and the second plug-in portion 11 are plugged into each other, adhesive can be injected between the first plug-in portion 21 and the second plug-in portion 11 to connect and fix the first plug-in portion 21 and the second plug-in portion 11, thereby connecting and fixing the floor 10 and the door sill beam 20.

[0032] It should be noted that the plug-in fixation of the first plug-in portion 21 and the second plug-in portion 11 can improve the stability and firmness of the adhesive fixation between the floor 10 and the door sill beam 20, and the adhesive connection between the floor 10 and the door sill beam 20 is not easy to debond. That is, when the adhesive between the floor 10 and the door sill beam 20 has a tendency to debond, due to the limiting effect of the plug-in fit of the first plug-in portion 21 and the second plug-in portion 11, and the limiting of the first plug-in portion 21 and the second plug-in portion 11 will limit the debonding of the adhesive. With such an arrangement, the structural changes to the floor 10 and the door sill beam 20 are relatively small, and no additional cost is required, which facilitates the production and manufacturing of the frame 100.

[0033] Combine Figure 1-Figure 3 As shown, one of the first plug-in portion 21 and the second plug-in portion 11 is a plug-in protrusion, and the other is a plug-in groove. The plug-in protrusion extends into the plug-in groove and is plugged into the plug-in groove. Adhesive is provided in the plug-in groove.

[0034] Specifically, by setting one of the first plug-in portion 21 and the second plug-in portion 11 as a plug-in protrusion and the other as a plug-in groove, and by extending the plug-in protrusion into the plug-in groove, the plug-in fit of the plug-in protrusion and the plug-in groove can be achieved. This not only ensures the stability and reliability of the plug-in fit between the first plug-in portion 21 and the second plug-in portion 11, but also reduces the difficulty of the plug-in fit between the first plug-in portion 21 and the second plug-in portion 11.

[0035] Furthermore, after the plug-in protrusion and the plug-in groove are plugged in, by injecting adhesive into the plug-in groove, the adhesive can completely wrap the outside of the plug-in protrusion and realize the bonding and fixation of the plug-in protrusion and the plug-in groove. With such a configuration, the plug-in cooperation of the plug-in protrusion and the plug-in groove can make the adhesive bond and fix the plug-in protrusion and the plug-in groove more firmly and not easy to debond, which can further improve the stability and reliability of the connection and fixation of the door sill beam 20 and the floor 10.

[0036] In other embodiments of the present invention, one of the floor 10 and the door sill beam 20 is provided with a first clamping portion, and the other is provided with a second clamping portion. One of the first clamping portion and the second clamping portion is a clamping protrusion, and the other is a clamping groove. After the clamping protrusion and the clamping groove are clamped together, they are bonded and fixed by adhesive. This can also improve the bonding strength of the floor 10 and the door sill beam 20 and prevent the floor 10 and the door sill beam 20 from debonding.

[0037] In some further embodiments of the present invention, the floor 10 and the door sill beam 20 may also be connected and fixed by an interference fit. After the floor 10 and the door sill beam 20 are interference fit, they are then bonded and fixed at the interference fit position using adhesive, which can further enhance the structural stability and firmness of the vehicle frame 100.

[0038] Therefore, by plugging and fitting the first plug-in portion 21 and the second plug-in portion 11, and then providing adhesive between the first plug-in portion 21 and the second plug-in portion 11, the floor 10 and the door sill beam 20 are plugged and fixed. This not only improves the stability and reliability of the adhesive fixation between the floor 10 and the door sill beam 20, but also prevents debonding between the door sill beam 20 and the floor 10. Moreover, it does not make the structure of the floor 10 or the door sill beam 20 overly complicated, and can optimize the structural design of the vehicle frame 100.

[0039] In some embodiments of the present invention, Figure 1-3 As shown, the plug-in protrusion is extended in the front-to-back direction as a whole, and the plug-in groove is extended in the front-to-back direction as a whole and corresponds to the plug-in protrusion.

[0040] Specifically, by extending both the plug-in protrusion and the plug-in groove in the front-to-back direction and making the plug-in protrusion and the plug-in groove correspond to each other as a whole, this not only can increase the plug-in matching area between the plug-in protrusion and the plug-in groove, thereby increasing the area of ​​the adhesive connecting and fixing the plug-in protrusion and the plug-in groove, but also can further improve the stability and firmness of the adhesive in bonding and fixing the floor 10 and the door sill beam 20.

[0041] In other embodiments of the present invention, there are multiple plug-in protrusions and they are spaced apart in the front-to-back direction, there are multiple plug-in slots and they are spaced apart in the front-to-back direction, and the multiple plug-in protrusions and the multiple plug-in slots are plugged in one-to-one.

[0042] Specifically, by providing a plurality of plug-in protrusions, and making the plurality of plug-in protrusions spaced apart in the front-to-back direction, providing a plurality of plug-in slots, and making the plurality of plug-in slots spaced apart in the front-to-back direction, and plugging and matching the plurality of plug-in protrusions and the plurality of plug-in slots in a one-to-one correspondence, the force uniformity of the plug-in protrusions and the plug-in slots in the front-to-back direction can be improved while ensuring the stability and firmness of the plug-in protrusions and the plug-in slots, thereby improving the uniformity of the adhesive in bonding the plurality of plug-in protrusions to the plurality of plug-in slots. With such a configuration, on the one hand, the weight of the vehicle frame 100 can be reduced, and on the other hand, the stability and reliability of the connection and fixation between the floor 10 and the door sill beam 20 can be ensured.

[0043] Combine Figure 3 As shown, the plug-in protrusion is provided with a glue guide groove 22, which extends in the left-right direction. Specifically, after the plug-in protrusion and the plug-in groove are plugged together and adhesive is injected between the plug-in protrusion and the plug-in groove, the adhesive may become stuck between the plug-in groove and the plug-in protrusion, resulting in uneven distribution of the adhesive between the plug-in groove and the plug-in protrusion. In other words, between the plug-in protrusion and the plug-in groove, there is more adhesive near the adhesive injection port, and less adhesive far from the adhesive injection port, or even failure to inject the intended amount of adhesive normally.

[0044] Therefore, by providing a glue guiding groove 22 on the plug-in protrusion and extending the glue guiding groove 22 in the left-right direction, the adhesive can enter the glue guiding groove 22 after entering between the plug-in protrusion and the plug-in groove, and flow in the glue guiding groove 22, so that the adhesive is evenly distributed between the plug-in protrusion and the plug-in groove. This can improve the effect of the adhesive on the bonding and fixing of the plug-in protrusion and the plug-in groove, reduce the risk of bonding failure between the plug-in protrusion and the plug-in groove, and further improve the structural stability of the frame 100.

[0045] Combine Figure 3 As shown, there are multiple adhesive guiding grooves 22, and the multiple adhesive guiding grooves 22 are spaced apart in the front-to-back direction. Specifically, by providing multiple adhesive guiding grooves 22 and spacing the multiple adhesive guiding grooves 22 in the front-to-back direction, the multiple adhesive guiding grooves 22 can guide more adhesive, thereby further improving the uniformity of adhesive distribution between the insertion protrusion and the insertion groove.

[0046] Combine Figure 1-3 As shown, the thickness of the plug-in protrusion in the vertical direction gradually decreases as it gradually extends toward the interior of the plug-in slot. Specifically, by gradually decreasing the thickness of the plug-in protrusion in the vertical direction as it gradually extends toward the interior of the plug-in slot, such a configuration can, on the one hand, play a guiding role in the plug-in fit between the plug-in protrusion and the plug-in slot, facilitate the plug-in fit between the plug-in protrusion and the plug-in slot, and prevent the plug-in protrusion and the plug-in slot from getting stuck. That is, during the plug-in fit between the plug-in protrusion and the plug-in slot, the end of the plug-in protrusion with a smaller thickness in the vertical direction first extends into the plug-in slot. As the plug-in protrusion gradually enters the plug-in slot, the thickness of the plug-in protrusion gradually increases, causing the plug-in protrusion and the side wall of the plug-in slot to abut against each other and guide each other, thereby making the plug-in fit between the plug-in protrusion and the plug-in slot smoother and more stable.

[0047] On the other hand, it can play a certain guiding role on the adhesive, making the adhesive more evenly distributed between the plug-in protrusion and the plug-in groove, that is, the adhesive is easy to flow from the side with larger thickness to the side with smaller thickness, which can further improve the stability and firmness of the adhesive in bonding the plug-in protrusion and the plug-in groove.

[0048] In one embodiment of the present invention, Figure 1As shown, the insertion protrusion is located on the sill beam 20, the insertion groove is located on the floorboard 10, and a flange portion 12 is provided on the exterior of the floorboard 10 on the side corresponding to the insertion groove facing the sill beam 20. The flange portion 12 is in close contact with the sill beam 20. Specifically, by providing the insertion protrusion on the sill beam 20, providing the insertion groove on the floorboard 10, and providing the flange portion 12 on the exterior of the floorboard 10 on the side corresponding to the insertion groove facing the sill beam 20, the flange portion 12 is in close contact with the sill beam 20, and the flange portion 12 and the sill beam 20 are in close contact with each other, the connection strength between the floorboard 10 and the sill beam 20 can be further improved.

[0049] In another embodiment of the present invention, Figure 2 The plug-in protrusion is located on the floor 10 and the plug-in groove is located on the door sill beam 20.

[0050] Combine Figure 1 As shown, adhesive is also provided between the flange portion 12 and the sill beam 20. Specifically, the flange portion 12 and the sill beam 20 can also be bonded and fixed together using adhesive, which further enhances the stability of the connection between the floor panel 10 and the sill beam 20. Furthermore, the adhesive between the flange portion 12 and the floor panel 10 and the adhesive between the insertion protrusion and the insertion groove are integrated and not independent of each other. Therefore, the adhesives in these two locations jointly enhance the connection strength between the floor panel 10 and the sill beam 20, thereby further enhancing the structural reliability of the vehicle frame 100.

[0051] In addition, the adhesive between the flange portion 12 and the floor 10 and the adhesive between the insertion protrusion and the insertion groove can be injected simultaneously, which can save the manufacturing process of the frame 100 while increasing the structural strength of the floor 10 and the door sill beam 20.

[0052] The vehicle according to the present invention may mainly include: the above-mentioned frame 100. Applying the above-mentioned frame 100 to the vehicle can improve the structural stability of the vehicle. When the vehicle is impacted, the door sill beam 20 and the floor 10 are not easily debonded, the structural strength is relatively large, and the structural design of the vehicle can be optimized.
