Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle door structures, and more specifically relates to a lower hinge reinforcement, a hinge assembly and a vehicle. Background Art

[0002] The door provides a passage for the driver and passengers to enter and exit the vehicle, isolates the interference from outside the vehicle, reduces side impact to a certain extent, and protects the occupants. The quality of the door is mainly reflected in the door's anti-collision performance, the door's sealing performance, the door's opening and closing convenience, and of course other indicators of usage functions.

[0003] Since the lower hinge reinforcement of the door is installed between the inner and outer panels of the door, and is located on the front and rear panels of the inner door panel, the installation space is limited, resulting in a relatively concentrated distribution of the installation points when arranging the installation points, resulting in low stiffness and strength of the lower hinge reinforcement. In order to achieve lightweighting of the entire vehicle, more and more doors are made of composite materials, while traditional door inner panels are sheet metal stampings. The performance of composite materials and traditional sheet metal parts is quite different, especially in terms of weight, which is much lighter than traditional sheet metal parts. If the strength of the lower hinge reinforcement is increased by increasing the thickness of the lower hinge reinforcement, it will impose a large weight burden on the entire door inner panel. Therefore, how to improve the strength of the lower hinge reinforcement without increasing its thickness is an urgent problem to be solved. Utility Model Content

[0026] Please also read Figures 1 to 3The lower hinge reinforcement member, hinge assembly and vehicle provided by the utility model are now described. The lower hinge reinforcement member 2 includes a reinforcement plate body 202 and a connecting flange 201 connected to the outer edge of the reinforcement plate body 202. The reinforcement plate body 202 and the connecting flange 201 are both bonded to the inner plate 1. The reinforcement plate body 202 also has a mounting position connected to the inner plate 1.

[0027] Compared with the prior art, the lower hinge reinforcement member provided by the utility model has a connecting flange 201 arranged at the outer edge of the reinforcement plate body 202. Since the plate surface of the connecting flange 201 and the plate surface of the reinforcement plate body 202 are arranged at an angle, compared with the lower hinge reinforcement member 2 being arranged as a flat plate structure, the strength of the lower hinge reinforcement member 2 is improved without changing the thickness of the lower hinge reinforcement member 2. In addition, the connecting flange 201 and the reinforcement plate body 202 are respectively bonded to the two adjacent plate surfaces of the inner plate 1, so that the entire lower hinge reinforcement member 2 can be fixed to the inner plate 1, the contact area with the inner plate 1 is increased, and the connection firmness with the inner plate 1 is improved. The scheme in the utility model does not have to completely rely on the installation position to be screwed or clamped to the inner plate 1, so that the position distribution of the installation position is more flexible, and the number of the installation positions can also be appropriately reduced to ensure the strength and rigidity of the lower hinge reinforcement member 2. In addition, the lower hinge reinforcement member 2 can be limited by two adjacent plate surfaces of the inner plate 1 to increase the stability of the lower hinge reinforcement member 2.

[0028] Optionally, the reinforcing plate body 202 and the connecting flange 201 are respectively bonded to the inner plate 1, which maximizes the contact area with the inner plate 1 and improves the firmness of the connection. Moreover, the bonding and fixing matching mounting position is connected to the inner plate 1 body to jointly fix the lower hinge reinforcement 2.

[0029] In some embodiments, see Figure 1 and Figure 3 The reinforcing plate body 202 also has a reinforcing portion protruding toward the side away from the inner plate 1.

[0030] In this embodiment, a reinforcing portion is provided on the reinforcing plate body 202 to further increase the strength of the reinforcing plate body 202 , and the reinforcing portion protrudes toward the side away from the inner plate 1 , does not interfere with the inner plate 1 , and does not affect the installation of the reinforcing plate body 202 .

[0031] In some embodiments, see Figure 1 The reinforcement portion includes a plurality of reinforcing ribs 2021 that are spaced apart in sequence, and the end of the reinforcing member extends to the outer edge of the reinforcing plate body 202 .

[0032] The end of the reinforcing rib 2021 extends to the outer edge of the reinforcing plate body 202, which maximizes the extension length of the reinforcing rib 2021, improves the torsional strength of the reinforcing plate body 202, and reduces the probability of deformation of the reinforcing plate body 202 after being subjected to force.

[0033] In some embodiments, see Figure 1 There are multiple mounting positions, and the multiple mounting positions are distributed on the periphery of the reinforcement part.

[0034] Distributing multiple installation positions on the periphery of the reinforcement part, after the installation positions are connected to the inner panel 1, not only can the outer edge of the reinforcement plate body 202 be fixed to improve the connection firmness, but the reinforcement part is located in the middle of the multiple installation positions, which can improve the torsional strength of the reinforcement plate body 202 and reduce the deformation probability of the reinforcement plate body 202.

[0035] In some embodiments, see Figure 1 The lower hinge reinforcement 2 also includes a reinforcement flange 203 connected to the outer edge of the reinforcement plate body 202, and the reinforcement flange 203 is bent toward a side away from the inner plate 1.

[0036] The reinforcing flange 203 can enhance the strength of the lower hinge reinforcement 2 and reduce the probability of deformation of the edge of the reinforcing plate body 202. In addition, the reinforcing flange 203 is bent toward the side away from the inner plate 1, which does not affect the contact between the reinforcing plate body 202 and the inner plate 1, thereby ensuring the contact area between the reinforcing plate body 202 and the inner plate 1 and improving the stability and firmness of the connection.

[0037] In some embodiments, see Figure 1 The connecting flanges 201 are provided with a plurality of reinforcing flanges 203 , and a reinforcing flange 203 is provided between two connected connecting flanges 201 .

[0038] On the periphery of the reinforcing plate body 202 , the reinforcing flanges 203 are arranged between two adjacent connecting flanges 201 . The alternating arrangement ensures the balanced strength of the reinforcing plate body 202 , avoids local fracture after being stressed, and increases the service life.

[0039] Optionally, a plurality of reinforcing flanges 203 are provided, and the reinforcing flanges 203 and the connecting flanges 201 are alternately distributed on the periphery of the reinforcing plate body 202 .

[0040] In some embodiments, see Figure 1 The connecting flanges 201 are provided with a plurality of connecting flanges 201 connected to opposite sides of the reinforcing plate body 202 and forming a “Z”-shaped structure with the reinforcing plate body 202 .

[0041] A plurality of connecting flanges 201 are connected to opposite sides of the reinforcing plate body 202. After the reinforcing plate body 202 is attached to the front and rear surfaces of the inner plate 1, the connecting flange 201 connected to one side of the reinforcing plate body 202 abuts against the main body of the inner plate 1, and the connecting flange 201 connected to the other side of the reinforcing plate body 202 is laid on the other surface of the inner plate 1, thereby limiting the reinforcing plate body 202 in the left and right directions, and improving the connection stability of the reinforcing plate body 202. In addition, the above structure further increases the contact area with the inner plate 1, and improves the firmness of the connection.

[0042] It should be noted that in order to improve the strength, the inner panel 1 has a reinforcing protrusion protruding toward the side away from the outer panel, and the reinforcing plate body 202 is connected to the connecting side of the reinforcing protrusion and the main body of the inner panel 1. A part of the connecting flange 201 abuts against the main body of the inner panel 1, and the other part of the connecting flange 201 contacts the reinforcing protrusion, thereby achieving three-sided contact with the inner panel 1. While increasing the contact area, the main body of the inner panel 1 and the reinforcing protrusion can also limit the reinforcing plate body 202 in the left and right directions.

[0043] In some embodiments, see Figures 1 to 3 The reinforcing plate body 202 is provided with a first mounting hole 2022 matched with the second mounting hole on the inner plate 1, the first mounting hole 2022 forms a mounting position, and a locking member 4 is inserted into the first mounting hole 2022 and the second mounting hole.

[0044] After the first mounting hole 2022 and the second mounting hole are aligned, the locking member 4 is inserted into the first mounting hole 2022 and the second mounting hole to fix the reinforcing plate body 202 to the inner plate 1. Compared with the bonding connection method, the solution in this embodiment is not affected by temperature and humidity, and the connection is more stable.

[0045] Optionally, the locking member 4 includes a bolt and a nut, the bolt is inserted into the first mounting hole 2022 and the second mounting hole, and the nut is locked with the bolt to achieve fixation of the reinforcing plate body 202 and the inner plate 1.

[0046] Optionally, the locking member 4 further includes a locking washer, which is located between the nut and the reinforcing plate body 202 to increase the strength of the connection between the reinforcing plate body 202 and the nut.

[0047] Optionally, the reinforcing plate body 202 and the connecting flange 201 are respectively bonded to the inner plate 1, and then the locking member 4 is inserted into the first mounting hole 2022 and the second mounting hole. The two connection methods cooperate to further improve the firmness of the connection.

[0048] Based on the same inventive concept, the utility model also provides a hinge assembly. Figures 1 to 3The hinge assembly includes any one of the above-mentioned lower hinge reinforcement members 2, and also includes a door hinge 3 arranged on the other side of the inner panel 1 relative to the reinforcement panel body 202.

[0049] The hinge assembly provided by the utility model adopts the above-mentioned lower hinge reinforcement 2, and a connecting flange 201 is set at the outer edge of the reinforcement plate body 202. Since the plate surface of the connecting flange 201 and the plate surface of the reinforcement plate body 202 are set at an angle, compared with the lower hinge reinforcement 2 being set as a flat plate structure, the strength of the lower hinge reinforcement 2 is improved without changing the thickness of the lower hinge reinforcement 2. In addition, the connecting flange 201 and the reinforcement plate body 202 are respectively bonded to the two adjacent plate surfaces of the inner plate 1, so that the entire reinforcement plate body 202 and the connecting flange 201 can be fixed to the inner plate 1, increasing the contact area with the inner plate 1 and improving the connection firmness with the inner plate 1. The solution in the utility model does not have to completely rely on the mounting position to be screwed or clamped to the inner plate 1, so that the position distribution of the mounting position is more flexible, and the number of mounting positions can also be appropriately reduced to ensure the strength and rigidity of the lower hinge reinforcement 2. In addition, the lower hinge reinforcement 2 can be limited by two adjacent plate surfaces of the inner plate 1 to increase the stability of the lower hinge reinforcement 2.

[0050] Based on the same inventive concept, the utility model also provides a vehicle, which includes any one of the hinge assemblies described above.

[0051] The vehicle provided by the utility model adopts the above-mentioned hinge assembly, and a connecting flange 201 is set at the outer edge of the reinforcing plate body 202. Since the plate surface of the connecting flange 201 and the plate surface of the reinforcing plate body 202 are set at an angle, compared with the lower hinge reinforcement 2 being set as a flat plate structure, the strength of the lower hinge reinforcement 2 is improved without changing the thickness of the lower hinge reinforcement 2. In addition, the connecting flange 201 and the reinforcing plate body 202 are respectively bonded to the two adjacent plate surfaces of the inner plate 1, so that the entire lower hinge reinforcement 2 can be fixed to the inner plate 1, the contact area with the inner plate 1 is increased, and the connection firmness with the inner plate 1 is improved. The solution in the utility model does not have to completely rely on the installation position to be screwed or clamped to the inner plate 1, so that the position distribution of the installation position is more flexible, and the number of installation positions can also be appropriately reduced to ensure the strength and rigidity of the lower hinge reinforcement 2. In addition, the lower hinge reinforcement 2 can be limited by two adjacent plate surfaces of the inner plate 1 to increase the stability of the lower hinge reinforcement 2.
