[0030] Reference below Figure 1-Figure 3 A threshold support 100 according to an embodiment of the utility model is described. By providing the threshold support 100, the structural strength of the front threshold beam can be increased, and a reinforcing cavity 1 is provided on the threshold support 100 to form a transmission channel for the impact force, and the height of the inclined surface 31 is constructed to be gradually reduced to adapt to the shape of the front threshold beam, so as to facilitate the installation of the threshold support 100. A force-bearing surface 21 is formed at the front end of the front area 2 to withstand the front impact force and reduce the crushing amount of the front threshold beam in the X direction. The front area 2 is connected to the rear area 3 and both extend in the front-to-back direction, so that the force-bearing area of the threshold support 100 in the Z direction can be increased and the crushing amount of the lower A-pillar can be reduced, thereby effectively reducing the intrusion amount of the front threshold beam and the lower A-pillar into the passenger compartment, which is beneficial to improving the safety of the vehicle.
[0031] like Figure 1As shown, according to a threshold support 100 of one embodiment of the utility model, the threshold support 100 is suitable for being installed in the front part of the front threshold beam, a hollow reinforcement cavity 1 is formed in the threshold support 100, the threshold support 100 includes a front area 2 and a rear area 3 distributed along the front-to-back direction, a force-bearing surface 21 is formed at the front end of the front area 2, at least a part of the top surface of the rear area 3 is constructed as an inclined surface 31, and the height of the inclined surface 31 is set to gradually decrease from the front to the rear.
[0032] Specifically, the threshold support 100 can be used to bear a part of the impact force, and can absorb and transmit the impact force. By installing the threshold support 100 in the front part of the front threshold beam, the structural strength of the front threshold beam can be enhanced through the threshold support 100, and the possibility of deformation and failure of the front threshold beam under the action of the impact force can be reduced. In addition, the threshold support 100 can also absorb and transmit part of the impact force transmitted to the front threshold beam, reduce the impact force borne by the front threshold beam, and further reduce the crushing amount of the front threshold beam. In addition, the threshold support 100 can also absorb and transmit the impact force from the tire, that is, share the impact force in the Z direction, which can reduce the risk of the lower A-pillar breaking under the action of the tire impact force, thereby reducing the risk of the front threshold beam and the lower A-pillar intruding into the passenger compartment.
[0033] At the same time, a reinforcement cavity 1 is formed in the sill support 100, and the reinforcement cavity 1 is used to enhance the structural strength of the sill support 100 and improve the ability of the sill support 100 to withstand impact force, thereby reducing the possibility of deformation and failure of the sill support 100 under the action of the impact force. Moreover, the reinforcement cavity 1 is constructed as a hollow cavity, and even if the reinforcement cavity 1 can form a transmission channel for the impact force, the impact force can be transmitted to other positions through the reinforcement cavity 1, effectively reducing the impact force borne by the front sill beam and the lower A-pillar, thereby reducing the possibility of the front sill beam and the lower A-pillar breaking under the action of the impact force. Moreover, the weight of the sill support 100 can also be reduced, which is beneficial to the arrangement of the sill support 100 on the vehicle.
[0034] Furthermore, the sill support 100 includes a front region 2 and a rear region 3 distributed along the front-to-back direction, a force-bearing surface 21 is formed at the front end of the front region 2, the force-bearing surface 21 is used to bear the impact force of the front side of the vehicle, and the front region 2 is connected to the rear region 3, that is, the impact force borne by the force-bearing surface 21 can be transmitted from the front region 2 to the rear region 3, which can effectively reduce the impact force borne by the front sill beam, and thus reduce the amount of crushing of the front sill beam in the X direction. Moreover, both the front region 2 and the rear region 3 extend along the front-to-back direction, which can increase the force-bearing area of the sill support 100 in the Z direction, that is, increase the ability of the sill support 100 to withstand the impact force in the Z direction, reduce the impact force transmitted to the lower A-pillar, and thus reduce the amount of crushing of the lower A-pillar.
[0035] At least part of the top surface of the rear area 3 is constructed as the inclined surface 31, that is, part of the top surface of the rear area 3 is constructed as the inclined surface 31, or the entire top surface of the rear area 3 is constructed as the inclined surface 31, and the inclined surface 31 extends obliquely relative to the up and down directions, that is, there is a certain angle between the inclined surface 31 and the horizontal plane, and the height of the inclined surface 31 gradually decreases from the front to the back, so that the inclined surface 31 is a plane, which can reduce stress concentration and avoid cracking failure, and make the inclined surface 31 adapt to the shape of the front sill beam, so as to facilitate the installation of the sill support 100 in the front sill beam, thereby ensuring the reliable operation of the sill support 100.
[0036] Therefore, by arranging the sill support 100 in the front part of the front sill beam, when the vehicle is subjected to impact force from the front side and the tire at the same time, the sill support 100 can absorb the impact force and transmit it backwards, thereby effectively reducing the impact force transmitted to the front sill beam and the lower A-pillar, thereby reducing the crushing amount of the front sill beam and the lower A-pillar, and reducing the intrusion amount of the front sill beam and the lower A-pillar into the passenger compartment.
[0037] According to the threshold support 100 of the embodiment of the utility model, the structural strength of the front threshold beam can be increased by providing the threshold support 100, and the reinforcement cavity 1 is provided on the threshold support 100 to form a transmission channel for the impact force, and the height of the inclined surface 31 is constructed to be gradually reduced to adapt to the shape of the front threshold beam, so as to facilitate the installation of the threshold support 100, and a force-bearing surface 21 is formed at the front end of the front area 2 to withstand the front impact force and reduce the crushing amount of the front threshold beam in the X direction. The front area 2 is connected to the rear area 3 and both extend in the front-to-back direction, which can increase the force-bearing area of the threshold support 100 in the Z direction and reduce the crushing amount of the lower A-pillar, thereby effectively reducing the intrusion amount of the front threshold beam and the lower A-pillar into the passenger compartment, which is beneficial to improving the safety of vehicle use.
[0038] In some embodiments, a reinforcement plate 4 is disposed in the sill support 100 . The reinforcement plate 4 is extended along the front-to-back direction and divides the reinforcement cavity 1 into reinforcement sub-cavities 11 spaced apart and distributed along the up-down direction.
[0039] Specifically, the sill support 100 is used to absorb and transmit the impact force. A reinforcing plate 4 is arranged in the sill support 100. The reinforcing plate 4 is used to improve the structural strength of the sill support 100, thereby improving the ability of the sill support 100 to withstand the impact force. The reinforcing plate 4 can also be used to absorb and transmit the impact force. At the same time, the reinforcing plate 4 is extended in the front-to-back direction, so that the impact force can be transmitted backward through the reinforcing plate 4, thereby improving the stability of the vehicle body when the vehicle is hit, and the arrangement area and length of the reinforcing plate 4 can be increased, thereby improving the reliability of absorbing and transmitting the impact force by using the reinforcing plate 4. In addition, the reinforcing plate 4 can divide the reinforcing cavity 1 into reinforcing sub-cavities 11 spaced apart in the upper and lower directions, that is, the reinforcing cavity 1 can include at least two reinforcing sub-cavities 11, thereby simultaneously transmitting the impact force through the at least two reinforcing sub-cavities 11, thereby improving the efficiency and reliability of transmitting the impact force, thereby effectively reducing the impact force borne by the front sill beam and the lower A-pillar, and reducing the risk of the front sill beam and the lower A-pillar invading the passenger compartment.
[0040] In some embodiments, the reinforcing plate 4 is multi-layered, and the multi-layered reinforcing plates 4 are spaced apart and distributed in the front door sill beam along the up-down direction.
[0041] Specifically, the reinforcing plate 4 is used to improve the structural strength of the sill support 100. The reinforcing plate 4 is constructed into multiple layers, that is, the reinforcing plate 4 can be two layers, three layers or more layers. The structural strength of the sill support 100 can be jointly improved by the multiple layers of reinforcing plates 4, and the reliability of enhancing the structural strength of the sill support 100 can be improved. In addition, the multiple layers of reinforcing plates 4 are spaced apart and distributed in the front sill beam along the up and down directions, so that the impact force can be jointly absorbed and transmitted backward by the multiple layers of reinforcing plates 4, thereby effectively improving the stability of the vehicle body, and the multiple layers of reinforcing plates 4 can divide the reinforcement cavity 1 into multiple reinforcement sub-cavities 11 along the up and down directions, and then the impact force can be jointly transmitted by the multiple reinforcement sub-cavities 11, thereby effectively improving the efficiency and reliability of transmitting the impact force.
[0042] In such Figure 1 and Figure 3 In the illustrated embodiment, the reinforcing plate 4 is three-layered, and the three-layer reinforcing plate 4 can jointly improve the structural strength of the threshold support 100, and the three-layer reinforcing plate 4 divides the reinforcing cavity 1 into four reinforcing sub-cavities 11, and the four reinforcing sub-cavities 11 can jointly improve the efficiency and reliability of transmitting the impact force.
[0043] In some embodiments, at least one layer of reinforcement plate 4 is provided with a first weight-reducing hole 41 ; or, each layer of reinforcement plate 4 is provided with at least one first weight-reducing hole 41 .
[0044] Specifically, the first weight-reducing hole 41 is used to reduce the weight of the reinforcing plate 4, and thus reduce the weight of the threshold support 100, which is beneficial to the installation of the threshold support 100 on the vehicle. The first weight-reducing hole 4 can be set on at least one layer of the reinforcing plate 4, that is, the first weight-reducing hole 41 can be set on one or two layers of the three reinforcing plates 4, or the first weight-reducing hole 41 can be set on all three reinforcing plates 4 to reduce the weight of the reinforcing plate 4, or the first weight-reducing hole 41 can be set on each layer of the reinforcing plate 4, and the number of the first weight-reducing holes 41 can be increased to enhance the effect of reducing the weight of the threshold support 100 through the first weight-reducing holes 41, and the number of the first weight-reducing holes 41 on each layer of the reinforcing plate 4 can be at least one, that is, one or more first weight-reducing holes 41 can be set on each layer of the reinforcing plate 4 to further increase the number of the first weight-reducing holes 41, effectively reducing the weight of the reinforcing plate 4, that is, reducing the weight of the threshold support 100.
[0045] For example, Figure 1 As shown, first weight-reducing holes 41 may be provided on the three layers of reinforcing plates 4 to increase the number of the first weight-reducing holes 41 and effectively reduce the weight of the threshold support 100. The number of the first weight-reducing holes 41 on each layer of reinforcing plates 4 may be the same or different. The number of the first weight-reducing holes 41 may be flexibly determined according to the size of the space on the reinforcing plates 4 while ensuring the structural strength of the reinforcing plates 4.
[0046] In some embodiments, the threshold support 100 further includes a top plate 5 , a bottom plate 6 and two side plates 7 , the top plate 5 and the bottom plate 6 are relatively distributed along the up-down direction, and the two side plates 7 are relatively distributed along the inside-outside direction.
[0047] Specifically, a top plate 5, a bottom plate 6 and two side plates 7 are provided in the threshold support 100. The top plate 5 and the bottom plate 6 are relatively arranged in the up-down direction, and the two side plates 7 are relatively distributed in the inside-outside direction. The top plate 5 and the bottom plate 6 can be connected at both ends of the top plate 5 and the bottom plate 6 by the two side plates 7, so that the threshold support 100 is a frame structure, so as to enhance the structural strength of the threshold support 100 while reducing the weight of the threshold support 100. In addition, a reinforcement cavity 1 can be jointly defined by the top plate 5, the bottom plate 6 and the two side plates 7, so that the impact force can be transmitted backward along the reinforcement cavity 1, and three layers of reinforcement plates 4 are connected between the two side plates 7, so that the three layers of reinforcement plates 4 can be fixed by the two side plates 7, thereby improving the working reliability of the reinforcement plates 4.
[0048] Also, it should be noted that the wall thickness of the top plate 5, the bottom plate 6, and the side plate 7 on the threshold support 100 can be 3 mm to improve the structural strength of the threshold support 100, and the inner and outer directions can be the directions shown in the figure. In actual use, the inner and outer directions can also be interchanged, and the threshold support 100 can work reliably.
[0049] The top plate 5 , the bottom plate 6 and / or the side plate 7 are provided with second weight-reducing holes 8 .
[0050] Specifically, the second weight-reducing hole 8 is used to further reduce the weight of the threshold support 100. The second weight-reducing hole 8 can be set on one or two of the top plate 5, the bottom plate 6 or the side plate 7, or the second weight-reducing hole 8 can be set on the top plate 5, the bottom plate 6 and the side plate 7. The weight of the threshold support 100 is further reduced by the second weight-reducing hole 8, which is beneficial to the setting of the threshold support 100 on the vehicle.
[0051] For example, Figure 1-Figure 2 As shown, second weight-reducing holes 8 are arranged on the top plate 5, the bottom plate 6 and the side plate 7, and the shapes, sizes and numbers of the second weight-reducing holes 8 on the top plate 5, the bottom plate 6 and the side plate 7 are not the same. The second weight-reducing holes 8 can be flexibly arranged according to the space size on the top plate 5, the bottom plate 6 and the side plate 7 while ensuring the structural strength of the top plate 5, the bottom plate 6 and the side plate 7.
[0052] In some embodiments, the extension length of the front region 2 along the front-to-back direction is set to be greater than the extension length of the rear region 3 along the front-to-back direction.
[0053] Specifically, the sum of the extension length of the front region 2 along the front-to-back direction and the extension length of the rear region 3 along the front-to-back direction is the length of the threshold support 100. The length of the threshold support 100 needs to be within a certain range and should not be too large or too small. If it is too large, the threshold support 100 cannot be installed in the front threshold beam, and if it is too small, the threshold support 100 will have insufficient ability to withstand impact force. When designing the threshold support 100, the extension length of the front region 2 can be made greater than the extension length of the rear region 3, that is, the extension length of the front region 2 can be made larger, the area of the threshold support 100 for bearing Z-direction impact force can be increased, and the transmission path of the front impact force can be extended, which is beneficial to improving the threshold support 100's ability to withstand impact force.
[0054] For example, Figure 1-Figure 2 As shown, the length of the top plate 5 along the front-to-back direction can be set to L1, which can be 133 mm, 135 mm or 137 mm, etc., and the length of the bottom plate 6 along the front-to-back direction can be set to L2, which can be 178 mm, 180 mm or 182 mm, etc. Even if the length of the top plate 5 is smaller than that of the bottom plate 6, the sill support 100 can be adapted to the shape of the front sill beam, which facilitates the installation of the sill support 100, and the extension length of the front area 2 can be made greater than the extension length of the rear area 3, which can improve the ability of the sill support 100 to withstand impact force.
[0055] In some embodiments, the height of the rocker support 100 in the up-down direction is greater than the width of the rocker support 100 in the in-and-out direction.
[0056] Specifically, the height of the threshold support 100 in the up-down direction and the width of the threshold support 100 in the inside-outward direction need to be within a certain range and should not be too large or too small. If it is too large, the threshold support 100 cannot be installed, and if it is too small, the threshold support 100 has insufficient resistance to impact force. When designing the threshold support 100, the height of the threshold support 100 can be made greater than the width of the threshold support 100, that is, the width of the threshold support 100 can be made smaller to facilitate the setting of the threshold support 100. At the same time, the height of the threshold support 100 can also be made larger, which is beneficial to increase the area of the force-bearing surface 21 and improve the threshold support 100's resistance to impact force.
[0057] Exemplarily, as shown in the figure, the height of the threshold support member 100 in the up-down direction can be set to D1, which can be 48 mm, 50 mm or 52 mm, etc., and the width of the threshold support member 100 in the inward-outward direction can be set to D2, which can be 43 mm, 45 mm or 47 mm, etc., that is, the height of the threshold support member 100 in the up-down direction can be greater than the width of the threshold support member 100 in the inward-outward direction, so as to facilitate the installation of the threshold support member 100 in the front threshold beam and improve the threshold support member 100's ability to withstand impact force.
[0058] The utility model also provides a front door sill assembly.
[0059] According to the embodiment of the utility model, the front threshold assembly includes a front threshold beam, a threshold extruded aluminum plate and any one of the above threshold support members 100, the threshold extruded aluminum plate and the threshold support member 100 are both installed in the front threshold beam, the threshold support member 100 is connected to the top of the threshold extruded aluminum plate, and the front end of the threshold extruded aluminum plate and the front end of the threshold support member 100 both extend to the front end of the front threshold beam.
[0060] Specifically, the front sill beam is used to enhance the rigidity of the vehicle body and provide additional support for the vehicle body. The sill extruded aluminum plate is used to absorb and disperse the impact force to protect the safety of the passengers. The sill support 100 is used to absorb and transmit the impact force to reduce the intrusion of the front sill beam and the lower A-pillar into the passenger compartment. The sill extruded aluminum plate and the sill support 100 are both installed in the front sill beam. The sill extruded aluminum plate and the sill support 100 can be installed through the front sill beam to ensure the reliable operation of the two. The structural strength of the front sill beam can also be improved through the sill extruded aluminum plate and the sill support 100 to reduce the possibility of deformation and failure of the front sill beam under the action of the impact force. At the same time, the sill support 100 is connected to the upper part of the sill extruded aluminum plate. The sill support 100 can share a part of the impact force in the Z direction through the sill support 100, so that the impact force borne by the sill extruded aluminum plate can be reduced, and then the possibility of deformation and failure of the sill extruded aluminum plate under the action of the impact force can be reduced.
[0061] Furthermore, the front end of the sill extruded aluminum plate and the front end of the sill support member 100 are extended to the front end of the front sill beam, that is, the sill extruded aluminum plate and the sill support member 100 are extended to the front end of the front sill beam, so that the sill extruded aluminum plate and the sill support member 100 can jointly bear the impact force on the front side, thereby effectively reducing the impact force on the front sill beam, reducing the crushing amount of the front sill beam, and reducing the risk of the front sill beam intruding into the passenger compartment.
[0062] In some embodiments, a plurality of support plates are disposed in the extruded aluminum plate of the door sill, and the plurality of support plates are spaced apart and distributed along the inner and outer directions.
[0063] Specifically, a support plate is arranged in the threshold extruded aluminum plate, and the support plate is used to improve the structural strength of the threshold extruded aluminum plate. In addition, a plurality of support plates are arranged in the threshold extruded aluminum plate, that is, the number of support plates arranged can be two, three or more, so that the structural strength of the threshold extruded aluminum plate can be jointly improved by the plurality of support plates, and the reliability of improving the structural strength of the threshold extruded aluminum plate can be improved. At the same time, the plurality of support plates are spaced apart and distributed along the inner and outer directions, that is, the plurality of support plates can be respectively arranged on the inner and outer sides of the threshold extruded aluminum plate, and then the structural strength of the threshold extruded aluminum plate can be enhanced from the inner and outer sides of the threshold extruded aluminum plate at the same time by the plurality of support plates, which can effectively improve the ability of the threshold extruded aluminum plate to withstand lateral impact force, and reduce the possibility of deformation and failure of the threshold extruded aluminum plate under the action of the impact force.
[0064] Also, it should be noted that by providing multiple support plates along the inner and outer directions on the door sill extruded aluminum plate, the number of support plates provided at the bottom plate of the vehicle can be reduced, which is beneficial for reducing the lateral impact force transmitted to the battery pack and improving the safety of the battery pack.
[0065] In other embodiments, the sill support 100 is connected to the sill extruded aluminum plate via a connecting piece.
[0066] Specifically, the threshold support 100 is disposed above the threshold extruded aluminum plate, and a part of the impact force in the Z direction can be shared by the threshold support 100 to reduce the impact force borne by the threshold extruded aluminum plate, that is, the threshold support 100 can protect the threshold extruded aluminum plate, and the threshold support 100 and the threshold extruded aluminum plate can be connected by a connector to make the two relatively fixed, thereby improving the reliability of the threshold support 100 protecting the threshold extruded aluminum plate, and it is also convenient to connect or separate the two, and then when the threshold support 100 or the threshold extruded aluminum plate is deformed and failed, the failed component can be replaced, which can reduce the subsequent maintenance cost. Among them, the connector can be a bolt.
[0067] The utility model further provides a vehicle.
[0068] The vehicle according to the embodiment of the utility model is provided with any of the above-mentioned front door sill assemblies. By providing the door sill support 100 and the door sill extruded aluminum plate in the front door sill assembly, the impact force on the front door sill beam can be reduced, the amount of crushing of the front door sill beam can be reduced, and the risk of the front door sill beam intruding into the passenger compartment can be reduced. Moreover, by providing the door sill support 100 above the door sill extruded aluminum plate, a part of the Z-direction impact force can be shared by the door sill support 100 to reduce the impact force on the door sill extruded aluminum plate, thereby reducing the possibility of deformation and failure of the door sill extruded aluminum plate under the action of the impact force, and reducing the impact force on the lower A-pillar, reducing the amount of crushing of the lower A-pillar, thereby effectively reducing the amount of intrusion of the lower A-pillar into the passenger compartment, which is beneficial to improving the safety of vehicle use.
