Description

Technical Field

[0001] This utility model relates to a simulation test device for the locking tongue of an automobile charging port, belonging to the technical field of automobile testing equipment. Background Technology

[0002] In the field of automotive manufacturing technology, it is often necessary to test and inspect various automotive components to check their dimensional accuracy and performance in order to study the failure mechanisms and analyze the causes of failure. With the increasing prevalence of electric vehicles, while some components of electric vehicles share certain similarities with those of traditional gasoline-powered vehicles, there are also many differences and requirements. The charging port cover of an electric vehicle is locked to the vehicle body via a spring-loaded latch in a hook-like manner. The latch needs to not only lock the charging port cover smoothly and easily but also provide appropriate pressure to reliably seal the charging port. To ensure the reliability of the latch, it is necessary to study its assembly accuracy and wear process during use to design a reasonable structure for the latch and related components. This requires suitable testing equipment to simulate the installation structure and working process of the latch. Utility Model Content

[0018] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0019] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0020] like Figure 1 and Figure 2 As shown, the present invention provides a car charging port latch simulation test device, including a mounting frame 1, on which a plug interface 3 is provided for the insertion of a locking pin 2 of the charging port cover; the mounting frame 1 is provided with a pin shaft 4, on which a latch is rotatably connected; the belly 6 of the latch has a pin hole 8 for connecting the pin shaft 4; the head 5 of the latch has a locking hook 9 for hooking the locking pin 2 of the charging port cover; the tail 7 of the latch is connected to a driving device, which can drive the latch to rotate so that the locking hook 9 moves closer to the plug interface 3 to hook the locking pin 2, or moves the locking hook 9 away from the plug interface 3 to disengage the locking pin 2.

[0021] This utility model provides a test platform for testing the installation of a car charging port latch, which can conveniently perform tests such as assembly dimension detection, assembly interference test, motion interference test, and wear life test on the car charging port latch. It provides reference and verification for the design and production of the latch. This utility model has a simple structure, is easy to operate, and has a low cost.

[0022] When the latch rotates, its rotational position should be limited to ensure it rotates within a suitable range. To limit the range of rotation, for example... Figure 2 As shown, a protruding first limiting block 10 is provided on the back of the latch, and a first limiting surface 11 is provided on the mounting bracket 1. When the lock hook 9 rotates to its maximum distance away from the insertion interface 3, the first limiting block 10 abuts against the first limiting surface 11. This limiting method ensures that the latch will not exceed its appropriate range of motion, preventing it from bumping into other parts or structures. Please refer to the reference. Figure 1 and Figure 2The back of the locking tongue is also provided with a protruding second limiting block 12, and the mounting bracket 1 is provided with a second limiting surface 13. When the locking hook 9 rotates to its minimum distance in the direction close to the insertion interface 3, the second limiting block 12 abuts against the second limiting surface 13. In this way, the locking hook 9 will not excessively bump against the locking post 2 of the charging port cover and cause unnecessary wear. As a more reasonable design method, such as Figure 2 As shown, the mounting bracket 1 has a third limiting block 14 protruding toward the back of the latch, and the first limiting surface 11 and the second limiting surface 13 are both disposed on the third limiting block 14.

[0023] As previously described, the latch is driven by a drive device to rotate forward or backward, causing the latch 9 to move closer to the insertion interface 3 and engage with the locking pin 2, or causing the latch 9 to move away from the insertion interface 3 and disengage from the locking pin 2. After completing the test action of engaging the locking pin 2, the latch needs to be reset. To facilitate the reset of the latch, an elastic element is provided between the tail 7 of the latch and the mounting bracket 1. The elastic element pushes the latch, causing the latch 9 to tend to rotate away from the insertion interface 3. The elastic element provides elastic restoring force for the reset of the latch. As a preferred embodiment, such as... Figure 2 As shown, the elastic element is a compression spring 15. To ensure that the elastic force provided by the compression spring 15 stably pushes the locking tongue, as... Figure 2 As shown, the mounting bracket 1 is provided with a guide post 16, and the compression spring 15 is sleeved on the guide post 16. The guide post 16 keeps the direction of the spring force of the compression spring 15 unchanged.

[0024] The driving device drives the locking tongue to rotate. In the automotive charging port locking tongue simulation test device of this utility model, it is necessary to have a device that can push the locking tongue to rotate clockwise so that the locking hook 9 moves closer to the insertion interface 3 and engages with the locking pin 2. The brake cable is a device that can provide thrust. It has a simple structure, wide application, and low cost. As a preferred embodiment, the driving device is a brake cable that can provide thrust. The brake cable usually includes an outer guide sleeve 17 and a steel wire 19 disposed in the guide sleeve 17. The steel wire 19 is driven by the driving handle and can be pushed or pulled axially in the guide sleeve 17. The guide sleeve 17 provides support and guidance for the steel wire 19, so that the steel wire 19 can only move axially along the inner hole of the guide sleeve 17. In order for the steel wire 19 in the brake cable to move stably along the inner hole of the guide sleeve 17, the guide sleeve 17 needs to maintain good rigidity. For this reason, such as Figure 2 As shown, the mounting bracket 1 is provided with a stabilizing sleeve 18, and the guide sleeve 17 of the brake cable is inserted into the stabilizing sleeve 18. The stabilizing sleeve 18 can strengthen the support of the guide sleeve 17, so that the guide sleeve 17 maintains sufficient rigidity and will not bend under a large load.

[0025] Based on the technical solutions of the above embodiments, the automotive charging port latch simulation test device of this utility model provides a test platform for the simulation test of the latch, which can conveniently perform assembly dimension detection on the automotive charging port latch, simulate motion interference test under real working conditions, wear life test and other test items. It has a simple structure, is easy to operate and has a low cost.

[0026] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0027] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
