Abstract
Description
Technical Field
[0001] This utility model relates to the field of hinges, and in particular to a durability testing bench for automotive rotary door hinges. Background Technology
[0002] For general hinged single-axis flip-type doors, the testing facilities are simple and easy to operate, and the opening and closing durability test can be performed without simulating the installation of a car door body. However, the opening and closing trajectory of a swivel door is different. The connection between the door and the car body involves not only the swivel door hinge, but also the drive bracket, balance bracket, cylinder and balance strut. At the same time, the opening and closing durability of a swivel door must also consider the stress factor of the hinge bearing the weight of the door when the door is opened and closed. Therefore, a special test bench needs to be designed. Utility Model Content
[0003] Based on this, it is necessary to consider not only the influence of the drive bracket, balance bracket, cylinder and balance strut on the opening and closing trajectory of the swivel door, but also the stress factor of the hinge bearing the weight of the door when opening and closing. Therefore, it is necessary to design a special test bench and provide a durability test bench for automotive swivel door hinges.
[0004] This utility model provides a durability testing bench for automotive rotary door hinges, comprising:
[0005] Base plate;
[0006] The vehicle body simulation bracket is fixed to the surface of the base plate and perpendicular to the base plate. It has a first fixing block, a second fixing block and a third fixing block. The first fixing block has a first mounting bracket, the second fixing block has a second mounting bracket and the third fixing block has a third mounting bracket.
[0007] A hinge, rotatably connected to the first mounting bracket;
[0008] The door simulation frame is fixed to the side wall of the hinge;
[0009] The balance strut is rotatably connected between the second mounting bracket and the hinge;
[0010] The cylinder is rotatably connected between the third mounting bracket and the hinge.
[0011] In one embodiment, a door closing sensor and a door opening sensor are fixedly connected to the surface of the vehicle body simulation bracket.
[0012] In one embodiment, a counterweight is fixedly connected to the inner wall of the simulated door frame.
[0013] In one embodiment, the hinge includes a body panel, a drive panel is disposed on the surface of the body panel, a door frame panel is disposed on the side wall of the drive panel, the door frame panel is perpendicular to the drive panel, the body panel is parallel to the drive panel, the body panel is connected to a first mounting bracket, the door frame panel is connected to a door simulation frame, and the balance strut and the cylinder are both connected to the drive panel.
[0014] In one embodiment, a mounting block is fixedly connected between the door frame and the simulated door frame, and the mounting block is T-shaped.
[0015] In one embodiment, a reinforcing plate is fixedly connected between the base plate and the vehicle body simulation bracket.
[0016] The aforementioned automotive rotary door hinge durability testing bench involves fixing a vehicle body simulation bracket to the surface of a base plate, then mounting the hinge on a first mounting bracket, fixing a door simulation frame to the side wall of the hinge, installing a balance strut between a second mounting bracket and the hinge, and installing a cylinder between a third mounting bracket and the hinge. The number of opening and closing durability tests can be counted by changing the air intake direction of the cylinder pipe, thus facilitating the testing of the durability of the automotive rotary door hinge. The bench is simple to operate and easy to use. Attached Figure Description

[0028] The following is combined Figures 1-3 This invention describes a durability testing bench for automotive rotary door hinges.
[0029] like Figure 1 and Figure 2 As shown, in one embodiment, a vehicle rotary door hinge durability testing bench includes a base plate 100, a vehicle body simulation bracket 200, a hinge 300, a door simulation frame 400, a balance strut 500, and a cylinder 600.
[0030] The vehicle body simulation bracket 200 is fixed to the surface of the base plate 100 and is perpendicular to the base plate 100. The vehicle body simulation bracket 200 has a first fixing block 210, a second fixing block 220 and a third fixing block 230. The first fixing block 210 has a first mounting bracket 240, the second fixing block 220 has a second mounting bracket 250 and the third fixing block 230 has a third mounting bracket 260.
[0031] It should be noted that the first fixing block 210, the second fixing block 220 and the third fixing block 230 can reserve opening and closing space for the hinge 300 to prevent the door simulation frame 400 from colliding with the body simulation bracket 200 during the testing process, thereby affecting the test results.
[0032] The hinge 300 is rotatably connected to the first mounting bracket 240.
[0033] The door simulation frame 400 is fixed to the side wall of the hinge 300. The design structure of the door simulation frame 400 is calculated and designed based on the weight and center position of the door.
[0034] The balance strut 500 is rotatably connected between the second mounting bracket 250 and the hinge 300.
[0035] Cylinder 600 is rotatably connected between the third mounting bracket 260 and hinge 300.
[0036] This automotive rotary door hinge durability testing bench involves fixing a vehicle body simulation bracket 200 to the surface of a base plate 100, then mounting the hinge 300 on a first mounting bracket 240, fixing a door simulation frame 400 to the side wall of the hinge 300, installing a balance strut 500 between a second mounting bracket 250 and the hinge 300, and installing a cylinder 600 between a third mounting bracket 260 and the hinge 300. The number of opening and closing durability tests can be counted by changing the air intake direction of the cylinder 600's air pipe, thus facilitating the testing of the durability of the automotive rotary door hinge. It is simple to operate and easy to use.
[0037] In this embodiment, a door closing sensor 270 and a door opening sensor 280 are fixedly connected to the surface of the vehicle body simulation bracket 200. The door closing sensor 270 and the door opening sensor 280 can detect whether the opening and closing position of the door hinge meets the design requirements.
[0038] In this embodiment, a counterweight 410 is fixedly connected to the inner wall of the door simulation frame 400, which facilitates the adjustment of the center of gravity of the door simulation frame 400 according to the weight and center position of the door, thereby making the test results more accurate.
[0039] It should be noted that, see [link / reference] Figure 3 The hinge 300 includes a body panel 310, a drive panel 330 is provided on the surface of the body panel 310, a door frame panel 320 is provided on the side wall of the drive panel 330, the door frame panel 320 is perpendicular to the drive panel 330, the body panel 310 is parallel to the drive panel 330, the body panel 310 is connected to the first mounting bracket 240, the door frame panel 320 is connected to the door simulation frame 400, and the balance strut 500 and the cylinder 600 are both connected to the drive panel 330.
[0040] In this embodiment, a mounting block 420 is fixedly connected between the door frame 320 and the door simulation frame 400. The mounting block 420 is T-shaped and there are three mounting blocks 420, which can make the connection between the door frame 320 and the door simulation frame 400 more stable, and at the same time, facilitate assembly and disassembly.
[0041] In this embodiment, a reinforcing plate 110 is fixedly connected between the base plate 100 and the vehicle body simulation bracket 200, which improves the stability between the base plate 100 and the vehicle body simulation bracket 200.
[0042] If the hinges are directly installed on the actual car door body for durability testing, the repeated assembly and replacement of the hinges is inconvenient due to the complexity of the car door body structure. Therefore, it is necessary to design a test bench that matches the weight and center of gravity of the car door and has a simplified installation structure on the car body. This will make disassembly and replacement relatively convenient and save time in the test operation.
[0043] It should be noted that by installing two sets of vehicle body simulation brackets 200 and their corresponding components on the base plate 100, the hinges of the rotary doors on both sides of the vehicle can be tested simultaneously, which improves work efficiency.
[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
