Description

Technical Field

[0001] This utility model relates to a testing fixture, and more particularly to a manual testing device for displaying finished car cover products. Background Technology

[0002] The invention and widespread use of automobiles have brought immeasurable convenience to people's transportation. However, as small civilian vehicles exposed to the elements for extended periods, their original paint suffers from a relatively high annual wear rate. As people increasingly seek personalized appearances for their vehicles, most car owners invest in appropriate vehicle accessories to improve and enhance the surface's resistance to damage.

[0003] This has also spurred the growth of a large number of car cover manufacturers and private businesses specializing in vehicle maintenance and decoration. Before manufacturers can launch newly developed car covers to the market, they need to conduct a series of physical tests on the finished products by distributors, specifically testing the puncture resistance and scratch resistance of the covers. However, car covers are usually produced in rolls, and simply laying them flat cannot achieve the desired testing effect, nor can they be tested directly on a real car after coating. This fails to meet the needs of distributors and end users to fully understand the product's performance. Summary of the Invention

[0004] The purpose of this invention is to provide a manual testing device for the scratch and puncture resistance of car covers, thereby solving the problem of making it convenient to conduct physical testing on car covers.

[0005] The technical solution of this utility model to achieve the above-mentioned objective is a manual testing device for the scratch and puncture resistance of car covers, including a box-type base and a matching operating pen. The box-type base has a pair of front and rear side walls with a larger area, a pair of side walls with a smaller area, and a hollow inner cavity. The front and rear side walls are provided with a number of linear grooves and through holes extending into the inner cavity. The car cover to be tested is attached to the surface of the front and rear side walls. One end of the operating pen is provided with a conical tip to puncture the holes under the car cover, and the other end of the operating pen is provided with a flat-headed insert to scratch the linear grooves under the car cover.

[0006] Furthermore, the bottom of the inner cavity of the box-type base is provided with a lighting fixture connected to the power supply circuit, and a switch fixed to any side wall is connected in series in the power supply circuit. When the lighting fixture is lit, the car cover shows a spot of light at the perforation position.

[0007] Furthermore, each of the front and rear sidewalls has dozens of perforations and more than three linear grooves on a single wall surface, wherein the perforations are arranged in an array and the linear grooves are vertically oriented and arranged in parallel.

[0008] Furthermore, the spacing between any perforation and adjacent perforations is such that when puncturing with an operating pen, the car cover completely adheres to the front or rear sidewall surrounding the current perforation.

[0009] Furthermore, any linear groove extends into the inner cavity or is set as a recessed groove, and the depth of the recessed groove satisfies the requirement that the car cover displays a strip-shaped light spot at the position of the linear groove when the inner cavity is illuminated.

[0010] Furthermore, the front or rear side wall of the box-type base is provided with a groove for storing the pen.

[0011] Furthermore, the pen is integrally formed from an iron rod and is adsorbed and stored on any side wall with embedded magnets.

[0012] The technical effects and advancements of this manual testing device are as follows: The device provides a physical carrier for simulating the application of a car cover to a vehicle, and provides a space for the car cover to be punctured or scratched. Based on the car cover to be tested pre-applied by the manufacturer, it is convenient for purchasing personnel to operate on-site and intuitively feel the protective performance of the car cover in practical use in terms of puncture resistance and scratch resistance. Moreover, the car cover can be torn off and reapplied, and the reusability of this manual testing device is very significant. Attached Figure Description

[0013] Figure 1 This is a three-dimensional structural diagram of the manual testing device of this utility model. Detailed Implementation

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master, and thus to make a clearer definition of the protection scope of this utility model.

[0015] This utility model innovatively proposes a manual testing device for the scratch and puncture resistance of car covers, in order to solve the problem of convenient physical testing of car covers when they are not actually applied to a car.

[0016] This utility model discloses a manual testing device for scratch and puncture resistance of car covers, comprising a box-type base 1 and a matching operating pen 2. The box-type base 1 has a pair of front and rear side walls with a larger area, a pair of side walls with a smaller area, and a hollow inner cavity. The front and rear side walls are provided with a plurality of linear grooves 12 and perforations 11 extending into the inner cavity. The car cover 3 to be tested is attached to the surface of the front and rear side walls. One end of the operating pen 2 is provided with a conical tip 21 to correspond to the perforations and punctures under the car cover, and the other end of the operating pen is provided with a flat-headed insert 22 to correspond to the scratching of the linear grooves under the car cover.

[0017] The box-shaped base can be formed from rigid materials such as steel sheets or plexiglass sheets. The car cover to be tested is applied from the front side wall to the back side wall using a common technique, ensuring that the cover completely covers the perforations and linear grooves with a smooth surface. However, the perforations and linear grooves on the back of the cover create a space that can be stretched and recessed. During testing, the conical tip of the testing pen is pressed against a perforation on the cover, allowing for a direct and intuitive assessment of the cover's tensile and puncture resistance, such as what kind of external force will cause the cover to dent or puncture. Similarly, by using the flat tip of the testing pen (simulating an unopened knife) against a linear groove on the cover and sliding it in one direction to simulate scratching with a hard object, the scratch resistance of the cover can be directly assessed, such as the extent of deformation and denting or whether it is easily scratched.

[0018] From a more detailed and optimized implementation perspective, the bottom of the inner cavity of the aforementioned box-type base is equipped with a lighting fixture 13 connected to the power supply circuit, and a switch 14 fixed to any side wall is connected in series in the power supply circuit. When the lighting fixture is lit, a spot of light 31 can be seen at the perforation position of the car cover 3. Here, the power supply circuit is a conventional closed-loop circuit with a power supply, that is, each lighting fixture distributed in space is connected in series with the switch and the power supply, so the figure is omitted.

[0019] In the illustrated embodiment, the front and rear sidewalls each have sixty perforations and six linear grooves. The perforations are arranged in a 10-horizontal-6-vertical array, and the spacing between any perforation and its adjacent perforation is sufficient to ensure that the car cover fits completely against the front or rear sidewall surrounding the perforation when punctured with an operating pen. The linear grooves are vertically oriented and arranged side by side, with each linear groove extending into the inner cavity or serving as a recessed groove. The depth of the recessed groove is sufficient to allow the car cover to display a strip-shaped light spot 32 at the location of the linear groove when the inner cavity is illuminated.

[0020] A preferred embodiment also includes a recess 15 on the front or rear side wall of the box-type base for storing the operating pen. During non-testing periods, the operating pen, an accessory to the manual testing device, can be stored there to prevent accidental loss. Furthermore, the operating pen is typically required to be of a relatively hard material; it can also be integrally formed from an iron rod and magnetically stored on either side wall containing an embedded magnet.

[0021] In summary, the above description and detailed embodiments of the manual testing device of this utility model demonstrate that this solution possesses substantial features and advancements: the device provides a physical carrier for simulating the application of a car cover to a vehicle, and provides a space for the car cover to be punctured or scratched. Based on the car cover to be tested pre-applied by the manufacturer, it facilitates on-site operation for purchasing personnel, allowing them to intuitively experience the puncture and scratch resistance performance of the car cover in its practical state; moreover, the car cover can be removed and reapplied, making the manual testing device highly reusable.

[0022] In addition to the above embodiments, the present invention may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
