Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a flipping test fixture for a foldable trunk lid. Background Technology

[0002] A car trunk folding cover is a type of foldable trunk cover, mainly used to improve space utilization, protect items, and enhance ease of use.

[0003] The materials used for trunk lids are mainly high-density fiberboard, multi-layer composite board, and PP honeycomb board. While the lid itself is not easily broken, the folded areas are the weakest points. Therefore, the rotational durability of the trunk lid determines its service life. According to Q / LPYSJ 0023-2023 "General Technical Conditions for Luggage Compartment Interior Parts," a rotational durability test is necessary to verify the lifespan of the trunk lid. Therefore, the market demands a tooling solution to meet this requirement. Utility Model Content

[0004] The purpose of this invention is to provide a flipping test fixture for a foldable luggage compartment lid to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical measures: a flipping test fixture for a foldable luggage compartment cover, comprising a frame as a base, on which a worktable is provided, characterized in that: a stop block for limiting the foldable luggage compartment cover is provided on the worktable, and a pressing cylinder for pressing the foldable luggage compartment cover is provided on the worktable; the other end of the foldable luggage compartment cover is fixed by a clamping rod, the clamping rod is mounted and fixed on a rocker arm, and the other end of the rocker arm is fixed on a rotating shaft, the rotating shaft being driven by a motor through a synchronous belt, thereby realizing the back-and-forth flipping of the foldable luggage compartment cover.

[0006] Compared with the prior art, the advantages of this utility model are: by rotating the motor, the rocker arm drives the foldable luggage lid to flip back and forth. This flipping test fixture can verify the service life of the foldable luggage lid.

[0007] As an improvement of this utility model, the rocker arm is provided with a guide groove, and a fixed pivot is slidably disposed in the guide groove and fixedly connected to the foldable luggage compartment cover. The purpose of this design is that the fixed pivot, by inserting into the side of the foldable luggage compartment cover, further promotes the flipping of the foldable luggage compartment cover.

[0008] As an improvement of this utility model, a first counting sensor and a second counting sensor are provided on the workbench, with the first and second counting sensors positioned on the left and right sides of the motor, respectively. The purpose of this design is to use the first and second counting sensors in combination to count the number of times the foldable suitcase lid is flipped back and forth.

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Example 1 Please refer to Figure 1 -8.

[0021] This embodiment provides a flipping test fixture for a foldable luggage lid, including a frame 1 as the base, a control box 15 inside the frame 1, a worktable 2 on the frame 1, and two sets of stops 4 on the worktable 2 to limit the fixing part of the foldable luggage lid 3 (the foldable luggage lid 3 consists of a fixing part and a flipping part, which can be flipped and folded).

[0022] The workbench 2 is equipped with pressing cylinders 5 that press down on the foldable luggage compartment cover 3 (specifically, the fixed part of the foldable luggage compartment cover 3), with one set on each of the left and right ends. The other end of the foldable luggage compartment cover 3 (i.e., the flipping part of the foldable luggage compartment cover 3) is fixed by a clamping rod 6, which is mounted on a rocker arm 7. The other end of the rocker arm 7 is fixed to a rotating shaft 8, which is driven by a motor 9 through a synchronous belt 10, thereby realizing the back-and-forth flipping of the foldable luggage compartment cover 3. It should be noted that the motor 9 is a programmable electric servo type. The input signals from the first counting sensor 13 and the second counting sensor 14, etc., are fed back to the control box 15 for processing, and then control the various output signals, such as the actions of the motor 9 and the cylinders. These control methods are existing technologies and will not be described in detail here.

[0023] In the embodiments of this utility model application, please refer to Figure 3 The rocker arm 7 is provided with a guide groove 11, and a fixed pivot 12, which is fixedly connected to the foldable luggage compartment cover 3, is slidably disposed in the guide groove 11. The fixed pivot 12 further pushes the foldable luggage compartment cover 3 to flip by inserting into the side of the foldable luggage compartment cover 3.

[0024] In the embodiments of this utility model application, please refer to Figure 3 The workbench 2 is equipped with a first counting sensor 13 and a second counting sensor 14, which are located on the left and right sides of the motor 9, respectively. The first counting sensor 13 and the second counting sensor 14 work together to count the number of times the foldable luggage compartment lid 3 is flipped back and forth.

[0025] In the embodiments of this utility model application, please refer to Figure 6Since the clamping rod 6 protrudes due to its thickness when clamping the foldable luggage lid 3, and they are not on the same plane, a perforated part 16 is provided on the workbench 2 to allow the clamping rod 6 to avoid it. Its function is to ensure that the foldable luggage lid 3 can be laid flat.

[0026] In the embodiments of this utility model application, please refer to Figure 7 This is a cross-sectional view of the foldable luggage lid 3 of this utility model when reversed 90 degrees. The baffle 17 serves to support the foldable luggage lid 3, with the support point located at its folding section, which is made of soft carpet material. Simultaneously, during the flipping process, the baffle 17 can also flip the lid body, preventing it from detaching from the clamping rod 6.

[0027] In the embodiments of this utility model application, please refer to Figure 8 This is a cross-sectional view of the foldable suitcase lid 3 when it is laid flat. The clamping rod 6 has a U-shaped cross-section, with the upper side of the U-shape being shorter than the lower side, which facilitates the placement and rotation of the foldable suitcase lid 3. The folding part of the foldable suitcase lid 3 is supported by a retaining strip 17.

[0028] This embodiment provides a flipping test fixture for a foldable suitcase lid. For normal use, please refer to... Figure 4 This refers to the state of the foldable luggage cover 3 of this utility model when it is laid flat. Figure 5 Figure 6 shows the state of the foldable luggage lid 3 of this utility model when it is rotated 90 degrees. Figure 7 shows the state of the foldable luggage lid 3 of this utility model when it is rotated 180 degrees.

[0029] This embodiment provides a flipping test fixture for a foldable luggage compartment cover. According to Q / LP YSJ 0023-2023 "General Technical Conditions for Luggage Compartment Interior Parts", the foldable luggage compartment cover 3 is subjected to 500 cycles of 180-degree durability testing. During and after the test, the product must not exhibit visible cracks, delamination, blistering, shrinkage, warping, plasticizer exudation, wrinkles, curling edges, or any other defects that affect normal use.

[0030] The beneficial effect of this utility model is that by rotating the motor 9, the rocker arm 7 drives the foldable luggage lid 3 to flip back and forth. This flipping test fixture can verify the service life of the foldable luggage lid 3.

[0031] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
