Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of test benches, in particular to a scissor door test bench. BACKGROUND

[0002] The movement mode of the scissor door of an automobile is relatively special, which is a composite movement of lateral rotation and vertical lifting. The configuration of the scissor door is relatively less than that of the rotary swing door, the development experience of the automobile manufacturer is less, and the development difficulty is higher. Because the scissor door is vertically lifted during use, the opening and closing control parameters are more demanding on the weight and gravity center of the door. In addition to the possibility of affecting the speed and smoothness of the lifting and closing of the door, more importantly, it will affect the lifting hovering function of the door. In the current door development verification process, the door and the body-in-white enter the vehicle OTS stage for verification. After the verification part fails, optimization and change are carried out again for verification, which has a long cycle and high cost, and cannot meet the project development node delivery; in the development process of the scissor door, installation matching, structure change and arrangement change need to intervene in the simulation motion bench for early verification.

[0003] On the other hand, in the direction of electrification of the automobile manufacturer, the electric function configuration is becoming more and more rich, such as electric scissor door combined with radar detection, door electric suction and release function, frameless door and glass short drop function, etc. The rich electric control function needs earlier pre-research and joint debugging development verification. The door and the body-in-white enter the vehicle OTS stage for verification, which cannot meet the project node. The electric control function development of the electric scissor door depends more on the simulation motion bench verification.

[0004] In the prior art, no test bench for testing the scissor door has been searched. Other disclosed patents are all related to the test bench for rotary swing door, which cannot be applied to the scissor door.

[0075] With the rapid development of domestic cars, cars and various components on the car have begun to iterate and develop rapidly, and the scissor door is a research and development hotspot of the door structure. The movement mode of the scissor door is relatively special, which is a composite movement of lateral rotation and vertical lifting. Domestic manufacturers have little experience in the development of scissor doors and the development is difficult. Since the scissor door has lateral rotation and vertical lifting actions during opening and closing, the weight, center of gravity and opening and closing speed of the scissor door are extremely important. In the current development and verification process of the scissor door, verification needs to be performed in the OTS stage of the whole vehicle (the tooling sample of the whole vehicle has been completed, and trial assembly and verification are performed). If the scissor door fails or needs to be changed during verification, the verification and development cycle of the scissor door is long and the cost is high, which cannot meet the project development node delivery. In the verification process, the active connecting parts of the scissor door, such as the door hinge, support rod and door lock, need to be adjusted in position or size. The toughness of the aluminum alloy scissor door is poor, and it is difficult to support repeated disassembly and assembly, so the installation position needs to be adjusted again or a new sample needs to be produced for testing. In addition, due to the more stringent requirements of the scissor door on the center of gravity and weight, the test development of the scissor door with different weights and different centers of gravity also needs to be adjusted and tested multiple times, which also has the problem of difficult verification and testing. With the development of electric vehicles, electric functions are becoming more and more rich, such as electric scissor doors combined with radar detection, door electric attraction and release functions, frameless doors and glass short descent functions. Early pre-research and joint debugging development and verification are required for rich electric control functions. However, the test and development of these functions also need to be tested with the scissor door, but there is no related scissor door test bench for testing at present.

[0076] Although there are many test benches for rotating sliding doors disclosed in the prior art, these rotating sliding doors cannot be applied to the test of the lifting, closing and hovering functions of the scissor door. In the test and development process, the active connecting parts are easily damaged during the repeated disassembly, adjustment and installation process, and the service life is short. The test development of the scissor door with different weights and different centers of gravity also needs to be adjusted and tested multiple times. The test and development of the electric control function and the installation matching and verification work of the important modeling surface are also problems.

[0077] In view of the above technical problems, the present application provides a scissor door test bench, which is used for the development, verification and test control of the scissor door. Please refer to Figure 1 and Figure 2 The scissor door test bench comprises a test bench base 1, the test bench base 1 has a test platform arranged in the horizontal direction, and further comprises a door frame assembly 2 which is detachably arranged on the test platform. A scissor door assembly 3 which is adapted to the shape of the opening of the door frame assembly 2 and is rotatably arranged in the opening of the door frame assembly 2.

[0078] The scissor door assembly 3 and the door frame assembly 2 are connected together through a plurality of movable connecting pieces, and two ends of each movable connecting piece are connected with the scissor door assembly 3 and the door frame assembly 2 respectively. Figure 4 The movable connecting piece is provided with a detachable adjusting assembly 5 at least at one end (see Figure 4 ), one side of the detachable adjusting assembly 5 is connected with the scissor door assembly 3 or the door frame assembly 2, and the other side is connected with the end of the movable connecting piece. The detachable adjusting assembly 5 can adjust the relative position of the end of the movable connecting piece relative to the scissor door assembly 3 or the door frame assembly 2. It should be noted that the detachable adjusting assembly 5, the scissor door assembly 3, the door frame assembly 2 and the movable connecting piece can be detachably connected through bolts, screws, pins and the like.

[0079] Specifically, in the embodiment, the door frame assembly 2 is used to simulate the body door frame of the scissor door in the whole vehicle, and the scissor door assembly 3 is a scissor door assembly 3 in the early development stage, which at least includes a scissor door body. The scissor door assembly 3 and the door frame assembly 2 are connected together through a plurality of movable connecting pieces, and the movable connecting pieces include but are not limited to door hinges, door support rods, door locks and the like. The door hinges and the door support rods are used to control the upward lifting, hovering and downward landing of the scissor door assembly 3 relative to the door frame assembly 2, and the door lock is used to control the locking or unlocking of the scissor door assembly 3 relative to the door frame assembly 2. Therefore, the present application solves the problem of lack of test and control bench for the scissor door in the prior art by providing a scissor door test bench specially used for testing the scissor door.

[0080] More specifically, the movable connecting piece 4 is provided as a door hinge, and the connection mode of the two ends with the scissor door assembly 3 and the door frame assembly 2 is taken as an example for description (see Figure 5 ). One end of the movable connecting piece 4 (door hinge) is connected with the door frame assembly 2, and the other end is connected with the scissor door assembly 3. An installation seat is arranged between the door hinge and the door frame assembly 2. In the present application, a detachable adjusting assembly 5 is further arranged between the installation seat and the door frame assembly 2. One end of the detachable adjusting assembly 5 is detachably connected with the installation seat, and the other end is detachably connected with the door frame assembly 2. When it is necessary to adjust the position of the connection between the door hinge and the door frame assembly 2, the adjustment can be realized by adjusting the detachable adjusting assembly 5.

[0081] For example, in the development verification process of the scissors door, when the door hinge and the door frame assembly 2 need to be adjusted to move 3mm upward along the height direction of the vehicle body, in the traditional verification scheme, the door hinge needs to be disassembled first, then adjusted upward by 3mm, and then reinstalled. This repeated disassembly and installation may damage the connection structure of the door hinge and the door frame assembly 2, especially the scissors door made of aluminum alloy material, which is more likely to be damaged. In the scheme disclosed in the present application, by adjusting the detachable adjustment assembly 5 between the door hinge and the door frame assembly 2, for example, by adjusting the size between the detachable adjustment assembly 5 to increase by 3mm, the door hinge does not need to be repeatedly disassembled and adjusted.

[0082] For example, in another example, in the development verification process of the scissors door, when the door support rod needs to be adjusted, the end connected to the scissors door body needs to be adjusted along the length direction and the height direction of the scissors door body. At this time, two detachable adjustment assemblies 5 can be arranged at the end of the door support rod and the scissors door body, one of which can be adjusted along the length direction of the scissors door body, and the other can be adjusted along the height direction of the scissors door body. For example, in the test development process, it is found that the end of the door support rod and the scissors door body needs to be adjusted by 2mm along the length direction of the scissors door body, and also needs to be adjusted by 3mm along the height direction of the scissors door body. At this time, one of the detachable adjustment assemblies 5 is adjusted to adjust the end of the door support rod by 2mm along the length direction, and the other detachable adjustment assembly 5 is adjusted to adjust the end of the door support rod by 3mm along the length direction. Similarly, repeated disassembly and adjustment of the door support rod are avoided, and the development and test efficiency is higher and more accurate.

[0083] Therefore, those skilled in the art should understand that the detachable adjustment assembly 5 arranged between the end of the movable connecting piece 4 and the scissors door assembly 3 and the door frame assembly 2 is equivalent to an intermediate adjustment assembly. By adjusting the intermediate adjustment assembly, the movable connecting piece 4 is avoided from being repeatedly disassembled and adjusted with the scissors door assembly 3 or the door frame assembly 2, and has the advantages of simple adjustment and accurate and controllable adjustment and test.

[0084] Therefore, the present application discloses a scissors door test bench, which is specially used for testing the related performance of the scissors door in the early development stage, including but not limited to the opening and closing of the door, the center of gravity of the door, and the functional components of the door. The scissors door test bench disclosed in the present application comprises a bench base 1, a door frame assembly 2, and a scissors door assembly 3. The bench base 1 provides a test platform, the door frame assembly 2 is used to simulate the door frame of the scissors door installed on the vehicle, and the scissors door assembly 3 is used to simulate the scissors door.

[0085] Further, the scissor door test bench disclosed by the present application further comprises a plurality of movable connecting members 4, and the present application is provided with detachable adjusting components 5 between the movable connecting members 4, the door frame assembly 2 and the scissor door assembly 3. When the door is developed and verified in the early stage, the position of the movable connecting member 4 (for example, the door support rod) needs to be adjusted in the installation position of the scissor door assembly 3 and the door frame assembly 2. The position can be adjusted by detaching or adjusting the position or size of the detachable adjusting component 5, which is equivalent to adding an intermediate adjusting component. The position of the movable connecting member 4 relative to the scissor door assembly 3 and the door frame assembly 2 is indirectly adjusted through the detachable adjusting component 5, which avoids repeated disassembly and adjustment of the movable connecting member 4, thereby further avoiding the damage or damage of the movable connecting member 4 or the door caused by repeated disassembly of the movable connecting member 4, the scissor door assembly 3 or the door frame assembly 2, so that the adjustment and test of the scissor door and the movable connecting member 4 are more accurate and controllable, and the efficiency of the scissor door in the early test and development process is improved and the test and development cost is reduced.

[0086] Next, the structure of the detachable adjusting component 5 will be described. Figure 4 The detachable adjusting component 5 comprises a fixed component 51, a connecting component 52 and at least one adjusting component 53. The fixed component 51 is arranged on the scissor door assembly 3 or the door frame assembly 2. The connecting component 52 is arranged at the end of the movable connecting member 4. The at least one adjusting component 53 is arranged between the fixed component 51 and the connecting component 52. The adjusting component 53 adjusts the interval size between the fixed component 51 and the connecting component 52 to adjust the relative position of the end of the movable connecting member 4 relative to the scissor door assembly 3 or the door frame assembly 2.

[0087] Specifically, in this embodiment, the size between the fixed component 51 and the connecting component 52 can be adjusted by arranging the adjusting component 53, and then the size of the end of the movable connecting member 4 relative to the scissor door or the door is adjusted. The fixed component 51 can be a common fixed block, a fixed plate or the like connected or integrally formed with the scissor door assembly 3 or the door frame assembly 2. The connecting component 52 is detachably connected with the end of the movable connecting member 4. The connecting component 52 can also be a connecting block or a connecting plate. The adjusting component 53 between the fixed component 51 and the connecting component 52 can be various size-adjustable mechanisms or modules. For example, the adjusting component 53 can be arranged as a size-adjustable adjusting bolt, which is adjusted by the connecting length of the adjusting bolt. The adjusting component 53 can also be arranged as an adjusting plug plate, which adjusts the size between the fixed component 51 and the connecting component 52 by adjusting the number or size of the adjusting plug plate, and then adjusts the size of the movable connecting member 4.
