Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle door accessories, in particular to a vehicle door hinge reinforcement plate. Background Art
[0002] With the development of automobile technology, consumers have higher and higher requirements for the quality of automobile use. Door hinges are key components of car doors, and their quality is related to whether problems such as misalignment, abnormal noise and jamming will occur during the use of the door.
[0003] As cars are becoming lighter, car doors are also being lightened. In order to reduce the weight of the car doors while reducing the decrease in structural strength at the connection between the car doors and the hinges, a reinforcing plate is added to the connection between the car doors and the hinges. The reinforcing plate is located between the inner and outer door panels, fixed to the inner door panel, and replaces the thinner and weaker door panel to be connected to the hinges by bolts. However, since the reinforcing plate is generally only fixed to the inner door panel, the weight of the car door can only be transmitted to the reinforcing plate from one side of the inner door panel, so that the side of the reinforcing plate close to the inner door panel is stressed, and the side close to the outer door panel is almost unstressed, resulting in uneven stress. Long-term use may cause the reinforcing plate to deform, thereby affecting the service life of the reinforcing plate and the car door.
[0004] To this end, the utility model provides a vehicle door hinge reinforcement plate. Utility Model Content

[0009] Preferably, an arc section is provided in the middle part of the reinforcing plate body; the arc section is located between the threaded sleeve and the second connecting plate; through the above structure, the longitudinal load capacity of the reinforcing plate can be further improved, and when the outer panel of the door is hit, the rigid transmission of the impact force on the door and the body is reduced, thereby improving the safety performance of the car.
[0010] Preferably, a plurality of weight-reducing holes are provided in the middle of the second connecting plate and the first connecting plate; the shapes and sizes of the plurality of weight-reducing holes are different; through the above structure, the overall weight of the reinforcing plate can be reduced, which is conducive to achieving the goal of lightweighting the automobile.

[0022] like Figures 1 to 3 As shown, a vehicle door hinge reinforcement plate described in an embodiment of the utility model comprises a reinforcement plate body 1; a first connecting plate 12 is fixedly connected to one side of the reinforcement plate body 1; a second connecting plate 13 is fixedly connected to the other side of the reinforcement plate body 1; a pair of connecting holes 14 are opened in the middle of the reinforcement plate body 1; a pair of threaded sleeves 15 are fixedly connected to the side walls of the connecting holes 14; the pair of threaded sleeves 15 and the pair of connecting holes 14 are concentrically arranged; a pair of mounting grooves 16 are opened in the middle of the side of the second connecting plate 13 away from the reinforcement plate body 1; when working, the reinforcement plate body 1 is placed between the inner and outer panels of the vehicle door, and the first connecting plate 12 is welded to the inner panel of the vehicle door, and the inner panel of the outer panel of the vehicle door is welded to the inner panel of the vehicle door. A pair of connecting columns are fixedly connected at corresponding positions on the side, and when installing the vehicle door outer panel, the pair of connecting columns are placed inside a pair of mounting grooves 16, and then the vehicle door outer panel is connected with the vehicle door inner panel. After the connection between the inner and outer panels is completed, the vehicle door and the hinge are connected and installed by using the threaded cooperation between the bolts and the threaded sleeve 15. After the installation is completed, part of the weight of the vehicle door is transferred from the first connecting plate 12 to the bolts in the middle of the threaded sleeve 15, and the other part of the weight is transmitted from the connecting column fixed to the inner wall of the vehicle door outer panel to the second connecting plate 13, and then transmitted to the bolts in the middle of the threaded sleeve 15, so that the force on the reinforcement plate is more uniform, thereby improving the service life of the reinforcement plate and the vehicle door to a certain extent.
