[0033] See also Figures 1 to 4, this application provides a side collision reinforcement structure for an automobile. This side collision reinforcement structure for an automobile is used to be installed inside the sill beam 10 of the automobile. The side collision reinforcement structure for an automobile includes a reinforcement member 20 and a connecting member 30. Among them, the reinforcement member 20 is arranged inside the sill beam 10, and the connecting member 30 is connected to the reinforcement member 20 and is used to install the reinforcement member 20 inside the sill beam 10. Due to the existence of the connecting member 30, there is a gap between at least part of the outer wall of the reinforcement member 20 and the inner wall of the sill beam 10 to form a liquid passing channel 40. And, a liquid passing port 50 is opened on the reinforcement member 20, and the liquid passing port 50 is communicated with the liquid passing channel 40 to facilitate the flow of the electrocoating liquid. Preferably, a plurality of liquid passing ports 50 are provided and are distributed at intervals along the length direction of the reinforcement member 20.
[0034] Furthermore, the material of the reinforcement member 20 can be aluminum alloy, aluminum profile or extruded aluminum. In this embodiment, extruded aluminum profile is preferably used, and the overall structure is lightweight.
[0035] As Figure 2 , 3 shown, the reinforcement member 20 includes a housing 21 and an inner plate 23. An inner cavity 22 is arranged inside the housing 21. Specifically, the housing 21 is a hollow structure, and thus an inner cavity 22 is formed inside it. The inner plate 23 is arranged inside the inner cavity 22 and divides the inner cavity 22 into a plurality of cavities 221. In this embodiment, the inner plate 23 is arranged as one, so as to divide the inner cavity 22 into two cavities 221. Of course, in other embodiments, the inner plate 23 can also be arranged as a plurality, which is specifically selected according to actual needs. The liquid passing port 50 is opened on the housing 21 and is communicated with the cavity 221. In this embodiment, the liquid passing port 50 is opened at a position of the housing 21 corresponding to one of the cavities 221 to communicate this cavity 221 with the liquid passing channel 40. Of course, it is not limited to this, and liquid passing ports 50 can be opened at positions of the outer part of the housing 21 corresponding to the two cavities 221.
[0036] Preferably, when the inner plate 23 is arranged as one, the cross-section of the reinforcement member 20 is in a "day" - shaped structure. Compared with other commonly used "eye" - shaped designs, there is one less longitudinal structure in the middle of the reinforcement member 20, and relatively speaking, the volume is smaller, realizing the overall lightweight design. And there are fewer structures inside the reinforcement member 20, which is convenient for electrocoating. At the same time, the "day" - shaped structure also has a good anti - collision effect, realizing the balanced control of the acceleration and intrusion amount in the side collision condition of the car door.
[0037] Specifically, the housing 21 includes a top plate 211, a bottom plate 212, a first side plate 213, and a second side plate 214, and the top plate 211, the first side plate 213, the bottom plate 212, and the second side plate 214 are connected head to tail to form an inner cavity 22. The liquid port 50 can be provided only on the first side plate 213, or only on the second side plate 214, or both the first side plate 213 and the second side plate 214 are provided with the liquid port 50. In this embodiment, the liquid port 50 is provided on both the first side plate 213 and the second side plate 214 to ensure the complete flow of the electrophoretic liquid.
[0038] Specifically, one end of the inner plate 23 is connected to the first side plate 213, and the first side plate 213 is divided into a first plate body 213a and a second plate body 213b by the inner plate 23, the first plate body 213a is connected to the top plate 211, and the second plate body 213b is connected to the bottom plate 212. The other end of the inner plate 23 is connected to the second side plate 214, and the second side plate 214 is divided into a third plate body 214a and a fourth plate body 214b by the inner plate 23, the third plate body 214a is connected to the top plate 211, and the fourth plate body 214b is connected to the bottom plate 212. Preferably, the first plate body 213a and the third plate body 214a are inclined, and the width of the top plate 211 is smaller than the width of the inner plate 23, so that the first plate body 213a, the top plate 211, the third plate body 214a, and the inner plate 23 will be in a trapezoidal shape, and the enhanced structure is more stable.
[0039] Preferably, the thickness of the first side panel 213 and the second side panel 214 is greater than that of the inner panel 23, the thickness of the first side panel 213 and the second side panel 214 is greater than that of the bottom panel 212, and the thickness of the bottom panel 212 is greater than that of the inner panel 23. The first side panel 213 and the second side panel 214 are close to the vehicle body side and the fillet, which are the key load-bearing areas and can be appropriately thickened. The inner panel 23 is a non-collision load-bearing sensitive direction, and can be appropriately thinned to reduce weight, achieve partial deformation during collision, and ensure balanced control of the intrusion amount under collision conditions.
[0040] Furthermore, the thickness of the first plate 213a is greater than that of the second plate 213b, and the thickness of the third plate 214a is greater than that of the fourth plate 214b. The first plate 213a and the third plate 214a are in the load-bearing direction close to the vehicle body end, so they are appropriately thickened to improve the structural stability of the reinforcement 20.
[0041] In order to further reduce the weight of the reinforcement 20, a first through hole 24 is provided on the inner plate 23. Preferably, a plurality of first through holes 24 are provided, and the plurality of first through holes 24 are spaced apart along the length direction of the inner plate 23. A second through hole 25 is provided on the top plate 211. Preferably, a plurality of second through holes 25 are provided, and the plurality of second through holes 25 are spaced apart along the length direction of the top plate 211. A third through hole 26 is provided on the bottom plate 212. Preferably, a plurality of third through holes 26 are provided, and the plurality of third through holes 26 are spaced apart along the length direction of the bottom plate 212.
[0042] Since the first side plate 213 and the second side plate 214 are the main collision bearing positions, through holes can be appropriately set at the positions of the inner plate 23, the top plate 211, and the bottom plate 212, so as to reduce the weight of the reinforcement 20 without affecting the collision bearing. At the same time, the existence of the through holes also improves the adequacy of the flow of the electrophoresis liquid, effectively avoiding the situation of poor electrophoresis.
[0043] like Figure 3 , Figure 4 As shown, the connecting member 30 includes a connecting portion 31 and a support leg 32. The connecting portion 31 is connected to the reinforcement member 20, and the support leg 32 is arranged on the connecting portion 31, and is connected to the door sill beam 10. The support leg 32 is used to form a gap between the reinforcement member 20 and the door sill beam 10. The connecting portion 31 and the reinforcement member 20 can be connected by welding, bonding, riveting, etc., and the present embodiment adopts the riveting method. The support leg 32 and the door sill beam 10 can be connected by welding, bonding, riveting, etc., and the present embodiment adopts the welding method. The support leg 32 can be fixed on the connecting portion 31 by welding, bonding, riveting, etc., or it can be an integral structure with the connecting portion 31 and formed on the connecting portion 31 by bending. The present embodiment adopts an integral structure, which is easy to process, simple in structure, strong in connection stability, and strong in collision bearing capacity.
[0044] Further, the connecting member 30 is defined as at least a first connecting member 30a and a second connecting member 30b. Among them, at least one first connecting member 30a is provided and connected to the bottom plate 212, and at least two second connecting members 30b are provided and connected to the first side plate 213 and the second side plate 214, respectively, so as to stably install the reinforcement 20. The first connecting member 30a and the second connecting member 30b each include a connecting portion 31 and a supporting leg 32, the connecting portion 31 of the first connecting member 30a is connected to the bottom plate 212, and the supporting leg 32 is connected to the threshold beam 10. The connecting portion 31 of the second connecting member 30b is connected to the first side plate 213 and the second side plate 214, and the supporting leg 32 is connected to the threshold beam 10.
[0045] In the present embodiment, the first connecting member 30a is set to three, which are respectively arranged at the head, tail and middle position of the bottom plate 212. The second connecting member 30b is set to four, two of which are arranged at the head and middle position of the first side plate 213, and the other two are arranged at the middle and tail position of the second side plate 214. Therefore, the lengths of the first connecting member 30a and the second connecting member 30b do not need to be set too long, which simplifies the structure and reduces costs. And a multi-point support installation method is realized, the installation point is optimized, the risk of extruded aluminum flipping is reduced, the risk of poor electrophoresis rate in the car manufacturing stage is reduced, and the collision bearing capacity is improved. Of course, it is not limited to this. In other embodiments, the first connecting member 30a can also be set to two or more than three. The second connecting member 30b can also be set to two, three or more than four. It is specifically selected according to actual needs, as long as stable support is met.
[0046] Preferably, the connecting portion 31 of the first connecting member 30a is in a boss shape, so that after the first connecting member 30a connects the bottom plate 212 to the threshold beam 10, there will be a certain distance between the bottom plate 212 and the threshold beam 10, which is convenient for the electrophoresis liquid to pass through.
[0047] The present application also provides a car, which adopts the car side collision reinforcement structure described in any of the above embodiments.
[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
