Technical Field

[0001] The utility model belongs to the technical field of automobile testing, and relates to a durability test device for an automobile door limiter. Background Technique

[0002] The durability test of an automobile limiter is a key link to ensure the quality of automobile parts. The automobile limiter is mainly used to limit the opening and closing amplitude of components such as doors, and its durability is directly related to the safety, comfort and reliability during the use of the automobile.

[0003] At present, in the durability test device for automobile limiters, the existing technical solutions mainly use electric servo or hydraulic cylinders to implement the test process. The electric servo system can provide relatively precise control, and the hydraulic cylinder can generate greater force to simulate the stress conditions under actual working conditions. However, both of these methods have significant problems.

[0004] From the perspective of cost, due to its high-precision control components and complex circuit system, the overall cost of the electric servo system remains high. Similarly, the hydraulic cylinder also has high manufacturing process requirements and requires supporting corresponding hydraulic power sources, pipeline systems and control systems, all of which greatly increase the equipment cost.

[0005] In terms of site requirements, the electric servo system may require a large control cabinet and relevant wiring space, while the hydraulic cylinder system occupies a large site area due to the large volume of hydraulic equipment, including auxiliary equipment such as hydraulic pumping stations. This not only restricts the effective use of the site, but also may lead to the need for additional site expansion or re-layout planning, further increasing the operating cost of the enterprise.

[0006] In summary, the existing durability test devices for automobile limiters have problems such as high equipment cost and large site area requirements. Content of the Utility Model

[0007] The purpose of the utility model is to provide a durability test device for an automobile door limiter to solve the problems mentioned in the background technique.

The first fixing plates are hinged to the end parts of the expansion rods of the corresponding straight cylinders, and the bottom of the cylinder body of the straight cylinder is fixed on the base through a first hinge seat.

[0011] As a further improvement of an embodiment of the present invention, the first fixing plate extends towards the side of the straight cylinder and is exposed outside the first profile to form a hinge end, and one end of the straight cylinder is hinged to the hinge end.

[0012] As a further improvement of an embodiment of the present invention, the first profile is an aluminum profile.

[0013] As a further improvement of an embodiment of the present invention, the front end of the first carrier plate is fixed on a second fixing plate through a second hinge seat, and the second fixing plate is arranged on the base.

[0014] As a further improvement of an embodiment of the present invention, the second hinge seats are symmetrically distributed at two ends of the second fixing plate with the middle line of the second fixing plate as the boundary.

[0015] As a further improvement of an embodiment of the present invention, the base is composed of aluminum profiles and has a "day" - shaped structure. A third fixing plate is arranged on the base, and the bracket mounting plate is detachably mounted on the third fixing plate.

Embodiment

[0037] See Figures 1 - 3 As shown, a durability test device for an automotive door limiter includes a base 1, and the base 1 provides a stable support foundation for the entire test device. A bracket mounting plate 4 for detachably mounting one end of the door limiter 3 is horizontally arranged on the base 1. An end limit box mounting plate 5 is arranged above the bracket mounting plate 4, and a through hole for the limit arm to pass through is provided on the end limit box mounting plate 5 and the end limit box is detachably fixed on the end limit box mounting plate 5; one ends of a plurality of end limit box mounting plates 5 are fixed on a first carrier plate 6 and the other ends are fixed on a second carrier plate 7; the first carrier plate 6 is hinged to one end of the base 1, and the second carrier plate 7 is hinged to the opposite end of the base 1 through a straight cylinder 2.

[0038] Among them: The straight cylinder 2 is the power source of the device. Through its telescopic movement, it can drive the second carrier plate 7 hinged thereto to move, thereby providing dynamic force and displacement for the end limit box mounting plate 5 and the limit arm, simulating the opening and closing actions of the car door. The straight cylinder 2 has the characteristics of simple structure and stable power output, and can meet various requirements during the test process.

[0039] The door limiter 3 is the object to be tested. One end of the door limiter 3 is detachably mounted on the bracket mounting plate 4, and its limit arm passes through the through hole on the end limit box mounting plate 5 and is connected to the end limit box. This detachable mounting method facilitates the testing of different models of door limiters.

[0040] The first carrier plate 6 and the second carrier plate 7, as connecting components, transmit the power of the straight cylinder 2 to the end limit box mounting plate 5, enabling the end limit box mounting plate 5 to move stably under the action of the straight cylinder 2, thereby accurately testing the door limiter 3.

[0041] In the durability test device for automobile door limiter, the second carrier plate 7 includes a first profile 71 distributed transversely. This transversely distributed structural design helps to enhance the stability and load-bearing capacity of the entire carrier plate. The first profile 71 is provided with first fixed plates 72 and 73 at both ends, respectively. These two fixed plates have an important connection function. They are hinged with the ends of the telescopic rods of the corresponding straight cylinders. This hinged mode enables flexible motion transmission between the straight cylinders and the second carrier plate 7. When the straight cylinder is extended and retracted, the hinged structure between the ends of the telescopic rods and the first fixed plates 72 and 73 can accurately drive the second carrier plate 7 to perform corresponding movements. The bottom of the cylinder body of the straight cylinder is fixed to the base 1 through the first hinge seat 9. The first hinge seat 9 provides a stable support point for the straight cylinder, ensuring that the straight cylinder will not shake or move during operation, thereby ensuring that the entire test device can operate stably and effectively perform durability tests on automobile door limiters.

[0042] Furthermore, in the structural design of the automobile door stopper durability test device, the first fixing plates 72 and 73 have a unique structure to achieve effective connection with the straight cylinder 2. The first fixing plates 72 and 73 extend toward one side of the straight cylinder 2 and are exposed outside the first profile 71, thereby forming a hinged end. This hinged end is provided for hinged connection with the straight cylinder 2. One end of the straight cylinder 2 is accurately hinged on this special hinged end, and this design makes the connection between the straight cylinder 2 and the second carrier plate 7 more stable and flexible.

[0043] Specifically, the first profile 71 is an aluminum profile. Aluminum profiles have many advantages such as light weight, high strength, corrosion resistance, and easy processing. In the automobile door stopper durability test device, aluminum profiles are selected as the first profile 71, which can not only meet the structural strength requirements, but also contribute to the overall lightness and economy of the device.

[0044] In the automobile door stopper durability test device, the front end of the first carrier plate 6 is fixed to the second fixing plate 11 through the second hinge seat 10, and the second fixing plate 11 is arranged on the base 1. The distribution mode of the second hinge seat 10 here is very special. It is symmetrically distributed at both ends of the second fixing plate 11 with the middle line of the second fixing plate 11 as the boundary. This symmetrical distribution design can make the first carrier plate 6 more evenly stressed during the movement, ensuring the stability of the connection between the first carrier plate 6 and the base 1.

[0045] In this embodiment, the base 1 is composed of aluminum profiles. Aluminum profiles have the advantages of light weight, relatively high strength, corrosion resistance, etc., and are suitable for constructing the base of the test device. The base 1 has a structure in the shape of a Chinese character 'Ri', and this structural design not only gives the base better stability, but also can reasonably utilize materials while ensuring strength. A third fixing plate 8 is provided on the base 1, and its main function is to install the bracket mounting plate 4, and the bracket mounting plate 4 is detachably mounted on the third fixing plate 8. This detachable mounting method brings great convenience to the test. It is convenient to test door limiters of different types or specifications. Just replace the bracket mounting plate 4 with the corresponding door limiter according to the requirements, which greatly improves the versatility of the test device.

[0046] During the test process, the straight cylinder 2 performs telescopic movement according to the set program. When the cylinder extends or contracts, the second carrier plate 7 drives the limit box mounting plate 5 to move, and then the limit arm of the door limiter 3 makes corresponding movements in the limit box, simulating the opening and closing process of the car door. Through multiple cycles of simulation actions, the durability of the door limiter 3 is tested to detect its performance changes after long-term use.

[0047] The utility model aims to realize the durability test of the car door limiter. During the test process, the straight cylinder plays a key driving role. It can push multiple limit box mounting plates to flip and swing together, and this swinging action precisely simulates the actual state of the limit arm of the door limiter and the limit box when the car door opens and closes. The opening and closing of the car door in daily use are frequent and complex actions. Through the simulation of this device, the durability of the door limiter can be effectively tested.

[0048] This device has many advantages. Its structure is simple, without complex mechanical structures and numerous components, which not only facilitates the manufacture, installation and maintenance of the device, but also reduces the probability of the device malfunctioning. Particularly prominent is that it can conduct durability tests on multiple door limiters at one time, greatly improving the test efficiency. Moreover, this device only uses a straight cylinder as the driving source, and compared with traditional devices using electric servo or hydraulic cylinders, it significantly reduces the device cost. At the same time, due to its compact structure, the demand for site space is reduced, thereby also reducing the site cost.

Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
