Description

Technical Field

[0001] This utility model relates to the technical field of testing devices for automotive parts, and more specifically to a testing device for a vehicle side door drive mechanism. Background Technology

[0002] In recent years, as the automotive industry continues to transform towards electrification and intelligence, various automated automotive components have also achieved rapid development. Among them, the automatic side door opening and closing technology is frequently used by users in daily life, so the operational reliability of the side door drive mechanism will have a significant impact on the user experience.

[0003] The side door drive mechanism mainly consists of a housing and a push rod that can extend and retract relative to the housing. To verify the operational reliability of the side door drive mechanism, the product undergoes corresponding tests before leaving the factory. However, most current testing equipment can only test the linear extension and retraction performance of the push rod in the side door drive mechanism. In reality, car side doors open by rotating, and when the opening angle of the side door is large, or when the car travels on uneven roads such as slopes, the load on the side door drive mechanism will change significantly. Current testing equipment clearly cannot test these variations. Utility Model Content

[0004] The purpose of this invention is to solve the problem that most existing testing devices can only test the linear extension and retraction performance of the push rod of the side door drive mechanism. However, the side door of a car actually opens by rotation, and when the opening angle of the side door is large, or when the car is driving on uneven road sections such as slopes, the load on the side door drive mechanism will change significantly, which current testing devices obviously cannot test.

[0005] To address the aforementioned problems, this utility model provides a testing device for a vehicle side door drive mechanism, comprising a support plate, a positioning seat, a transition seat, and a support frame. The positioning seat and the transition seat are spaced apart and disposed on the same side of the support plate. The positioning seat has a first mounting portion, and the transition seat has a rotatable shaft with the axis of the shaft parallel to the support plate. The support frame includes a first end connected to the shaft and a second end extending toward the positioning seat. The second end has a second mounting portion, and the transition seat has a damping element that acts on the shaft and applies damping force.

[0006] In the above scheme, the support frame and the support plate are rotatably connected by a pivot. The push rod and the housing of the side door drive mechanism are respectively connected to the first assembly part and the second assembly part. Thus, when the push rod extends or retracts relative to the housing, the support frame rotates relative to the support plate, simulating the rotational opening and closing of the side door relative to the vehicle body. At the same time, the above scheme further adds a damping component to the pivot. The damping force when the pivot rotates relative to the adapter seat is adjusted by the damping component, thereby effectively simulating the different loads applied by the side door to the side door drive mechanism and realizing simulation testing under different driving environments.

[0007] In an improved embodiment, the adapter includes two bearing seats spaced apart and connected to the support plate, and the two ends of the rotating shaft are rotatably connected to the two bearing seats respectively, thereby making the rotation of the rotating shaft more stable and having a better load capacity.

[0008] In an improved embodiment, the damping element is a torsion spring, which is sleeved on the rotating shaft. One end of the torsion spring is connected to the adapter and the other end is connected to the rotating shaft, thereby making the structure compact and applying damping force to the rotating shaft through the torsion spring, resulting in good reliability.

[0009] In an improved embodiment, there are two torsion springs, which are sleeved on the rotating shaft. One end of each torsion spring is connected to an adapter and the other end is connected to the rotating shaft, thereby ensuring the uniformity of the damping force applied by the damping element to the rotating shaft.

[0010] In an improved embodiment, the support plate is further provided with an angle sensor, the probe of which is oriented toward the rotating shaft, thereby enabling real-time monitoring of the rotation angle of the rotating shaft.

[0011] In an improved embodiment, the first assembly part is used to connect the push rod of the vehicle side door drive mechanism, and the second assembly part is used to connect the housing of the vehicle side door drive mechanism, thereby adapting to most vehicle side door drive mechanisms.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Please see Figure 1 and Figure 2 The present invention provides a test device for a vehicle side door drive mechanism, comprising a support plate 1, a positioning seat 2, a transition seat 3, and a support frame 4. The positioning seat 2 and the transition seat 3 are spaced apart on the same side of the support plate 1. The positioning seat 2 is provided with a first mounting part 21. The transition seat 3 is provided with a rotatable shaft 5, and the axis of the shaft 5 is parallel to the support plate 1. The support frame 4 includes a first end connected to the shaft 5 and a second end extending toward the positioning seat 2. The second end is provided with a second mounting part 41. The transition seat 3 is provided with a damping member 6 that acts on the shaft 5 and applies damping force.

[0021] In this embodiment, the first assembly part 21 is used to connect the push rod of the vehicle side door drive mechanism, and the second assembly part 41 is used to connect the housing of the vehicle side door drive mechanism, thereby adapting to most vehicle side door drive mechanisms. The specific form of the first assembly part 21 and the second assembly part 41 can be adjusted according to the vehicle side door drive mechanism. For example, the first assembly part 21 and the second assembly part 41 can be threaded holes, and the push rod and housing of the vehicle side door drive mechanism are respectively connected and assembled with the first assembly part 21 and the second assembly part 41 by bolts.

[0022] In the above scheme, the support frame 4 and the support plate 1 are rotatably connected by the rotating shaft 5. The push rod and the housing of the side door drive mechanism are respectively connected to the first assembly part 21 and the second assembly part 41. Thus, when the push rod extends or retracts relative to the housing, the support frame 4 rotates relative to the support plate 1, simulating the opening and closing of the side door relative to the vehicle body. At the same time, the above scheme further adds a damping component 6 to the rotating shaft 5. The damping force when the rotating shaft 5 rotates relative to the adapter 3 is adjusted by the damping component 6, thereby effectively simulating the different loads applied by the side door to the side door drive mechanism, realizing simulation testing under different driving environments.

[0023] In this embodiment, the adapter 3 includes two bearing seats that are spaced apart and connected to the support plate 1. The two ends of the rotating shaft 5 are respectively rotatably connected to the two bearing seats, thereby making the rotation of the rotating shaft 5 more stable and the load capacity better.

[0024] In this embodiment, the damping element 6 is a torsion spring, which is sleeved on the rotating shaft 5. One end of the torsion spring is connected to the adapter 3 and the other end is connected to the rotating shaft 5, thereby making the structure compact and applying damping force to the rotating shaft 5 through the torsion spring, which has good reliability.

[0025] Furthermore, there are two torsion springs, which are sleeved on the rotating shaft 5. One end of the torsion spring is connected to the adapter 3 and the other end is connected to the rotating shaft 5, thereby ensuring the uniformity of the damping force applied by the damping element 6 to the rotating shaft 5.

[0026] As an improvement to the above embodiment, the support plate 1 is also provided with an angle sensor 7, the probe of the angle sensor 7 is set towards the rotating shaft 5, so as to monitor the rotation angle of the rotating shaft 5 in real time through the angle sensor 7.
