Description

Technical Field

[0001] This utility model relates to the field of automotive interior testing technology, specifically to a waterproof testing device for genuine leather seat covers. Background Technology

[0002] In the production of genuine leather car seat covers, waterproof performance is one of the key indicators for measuring product quality. Existing waterproof testing technologies mostly use static testing methods, which are difficult to simulate the dynamic stress and liquid contact states of seats in actual use scenarios. Most existing equipment uses static pressing methods, which cannot reproduce the shaking caused by bumps and turns when the vehicle is in motion. As a result, the waterproof performance of seat covers in wrinkled and stretched states cannot be tested, leading to a significant deviation from actual use scenarios.

[0003] According to the publicly disclosed waterproof testing device (Publication No.: CN208206413U), it includes: a machine base, a positioning component, a pressing mechanism, and a detector. The positioning component is mounted on the machine base to place and position the workpiece. An air inlet channel is provided on the side of the positioning component facing the workpiece, for introducing gas with a preset pressure. The pressing mechanism includes a support, a pressing drive component, and a pressing component. The support is mounted on the machine base, the pressing drive component is mounted on the support, and the pressing component is mounted on the driving end of the pressing drive component, with an air outlet channel on the side facing the positioning component. One end of the air outlet channel is connected to the detector via a conduit. The detector is mounted on the machine base to detect pressure changes in the air outlet channel. This waterproof testing device, by introducing air into the air inlet channel and observing any pressure changes in the detector, can quickly and accurately test the waterproof performance of the workpiece, improving testing efficiency and accuracy.

[0004] In the aforementioned application, by venting air into the air inlet channel and monitoring pressure changes, the waterproof performance of the workpiece was quickly and accurately tested, improving testing efficiency and accuracy. However, it could not simulate the shaking state of the seat while the vehicle was in motion. Therefore, we propose a waterproof testing device for genuine leather seat covers. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a waterproof detection device for genuine leather seat covers, which solves the problems of scene simulation distortion and low resource utilization in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a waterproof testing device for genuine leather seat covers, comprising: a device base, a test box support foot fixedly connected to the top of the device base, a test box fixedly connected to the top of the test box support foot, a water tank fixedly connected to the top of the device base, a test seat disposed inside the test box, and a shaking device disposed inside the test box.

[0007] The shaking device includes a motor base, the bottom of which is fixedly connected to the top of the device base. A drive motor is fixedly connected to the inner wall of the motor base. An active L-shaped transmission plate is fixedly connected to the output end of the drive motor. A transmission ring is rotatably connected to the side of the active L-shaped transmission plate. A sliding plate is fixedly connected to the top of the transmission ring. A groove is formed on the circumferential surface of the test chamber. The side of the sliding plate is connected to the inner wall of the groove. A test seat is fixedly connected to the inner circumferential surface of the transmission ring. A driven L-shaped transmission plate is rotatably connected to the circumferential surface of the transmission ring. A water outlet pipe is fixedly connected to the side of the water tank. A branch water pipe is fixedly connected to the circumferential surface of one end of the water outlet pipe. One end of the branch water pipe is fixedly connected to the side of the test chamber.

[0008] For example, in at least one embodiment of this utility model, a waterproof testing device for genuine leather seat covers further includes: a plurality of branch water pipes arranged in a circumferential array along the vertical central axis of the test chamber. The circumferentially arrayed branch water pipes can spray liquid onto the test seat from multiple directions, simulating water flow impacts at different angles, ensuring that all parts of the seat cover can undergo waterproof testing, avoiding partial omissions, and improving the comprehensiveness of the test.

[0009] The sliding plate and the sliding groove are provided in two quantities, and are symmetrical to each other along the vertical central axis of the transmission ring. The symmetrically distributed sliding plate and sliding groove provide bidirectional guidance for the transmission ring, balance the forces during shaking, prevent the transmission ring from shifting or jamming, ensure the stability of the shaking trajectory of the test seat, and improve the consistency of the testing process.

[0010] Two leak-proof plates are fixedly connected to the circumferential surface of the test chamber, and the leak-proof plates are located near the slide groove. The leak-proof plates can block liquids that may seep out of the slide groove, prevent water from flowing out of the test chamber and contaminating the device base or other components, keep the equipment dry, reduce component damage caused by liquid corrosion, and extend the service life of the equipment.

[0011] The test chamber has an observation window on its side, and the top of the water tank is fixedly connected to a water inlet. The observation window allows for real-time observation of water leakage from the seat cover during the test and timely recording of the test results.

[0012] According to another aspect, at least one embodiment of the present invention also provides a waterproof testing device for genuine leather seat covers, comprising: a recycling device disposed on the top of the device base, the recycling device including a first recycling water pipe, one end of the first recycling water pipe being fixedly connected to the side of a water tank, the other end of the first recycling water pipe being fixedly connected to a filter box, the bottom of the filter box being fixedly connected to the top of the device base, a second recycling water pipe being fixedly connected to the side of the filter box, one end of the second recycling water pipe being fixedly connected to the circumferential surface of a test box, a filter screen being snapped into the inner wall side of the filter box, a toothed gear being fixedly connected to the circumferential surface of the output shaft of the drive motor, a rack box being fixedly connected to the top of the device base, a spring being fixedly connected to the bottom of the inner wall of the rack box, a reciprocating rack being fixedly connected to one end of the spring, the reciprocating rack meshing with the toothed gear, and a cleaning brush being fixedly connected to the side of the reciprocating rack.

[0013] For example, in at least one embodiment of this utility model, a waterproof testing device for genuine leather seat covers further includes: the side of the cleaning brush is in contact with the side of the filter screen, and the diameter of the displacement trajectory of the cleaning brush is equal to the diameter of the filter screen. The cleaning brush makes full contact with the filter screen and its trajectory covers the filter screen, which can remove impurities from the filter screen, prevent filter screen blockage from affecting water circulation efficiency, reduce the frequency of manual cleaning, and ensure the continuous and stable operation of the recycling system.

[0014] The rack housing has a limiting groove on its side, the diameter of which is equal to the diameter of the filter screen. One end of the cleaning brush is slidably connected to the inner wall of the limiting groove. The limiting groove provides precise guidance for the cleaning brush, preventing it from shifting during reciprocating motion and ensuring that the cleaning brush always adheres to the surface of the filter screen, thus improving the stability and reliability of the cleaning effect.

[0015] The springs are provided in pairs, symmetrically arranged along the vertical central axis of the reciprocating rack. These symmetrical springs provide a balanced restoring force to the rack, ensuring a smooth return to its original position after the toothed gear disengages, reducing vibration and guaranteeing the regularity of the cleaning brush's reciprocating motion.

[0016] The water tank has a water level observation slot on its side, and the filter box has a filter screen observation slot on its side. The water level observation slot facilitates monitoring the water level in the tank and allows for timely water replenishment; the filter screen observation slot allows for a direct view of the filter screen's contamination level, facilitating timely replacement or cleaning, ensuring water circulation and filtration efficiency, and improving equipment maintenance efficiency.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] 1. In this invention, the shaking device drives an active L-shaped transmission plate to rotate via a drive motor. The transmission plate, through a transmission ring, causes the test seat to reciprocate along a sliding groove, simulating the shaking state of the seat during actual use. Combined with multi-angle water spraying from branch pipes in a circular array, it can comprehensively test the waterproof performance of genuine leather seat covers under dynamic conditions. The symmetrical sliding plate and groove structure ensure a stable shaking trajectory, while the leak-proof plate prevents liquid leakage, improving testing reliability and equipment durability.

[0019] 2. In this utility model, the recycling device utilizes the meshing of a toothed gear and a reciprocating rack to drive a cleaning brush to automatically clean the filter screen, preventing impurities from clogging it and ensuring water circulation efficiency. Symmetrical springs ensure smooth return of the cleaning brush, extending component lifespan. Water level and filter screen observation tanks facilitate real-time monitoring, and the recycling water pipe enables water resource recycling, reducing waste, lowering testing costs, and improving equipment maintenance convenience and environmental friendliness.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0027] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to 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.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-4The present invention illustrates a waterproof testing device for genuine leather seat covers in one embodiment, comprising: a device base 1, a test box support 2 fixedly connected to the top of the device base 1, a test box 3 fixedly connected to the top of the test box support 2, a water tank 4 fixedly connected to the top of the device base 1, a test seat 5 disposed inside the test box 3, and a shaking device 6 disposed inside the test box 3.

[0033] The shaking device 6 includes a motor base 601, the bottom of which is fixedly connected to the top of the device base 1. A drive motor 602 is fixedly connected to the inner wall of the motor base 601. An active L-shaped transmission plate 603 is fixedly connected to the output end of the drive motor 602. A transmission ring 604 is rotatably connected to the side of the active L-shaped transmission plate 603. A sliding plate 605 is fixedly connected to the top of the transmission ring 604. A groove 606 is provided on the circumferential surface of the test chamber 3. The side of the sliding plate 605 is connected to the inner wall of the groove 606. A test seat 5 is fixedly connected to the inner circumferential surface of the transmission ring 604. A driven L-shaped transmission plate 607 is rotatably connected to the circumferential surface of the transmission ring 604. A water outlet pipe 608 is fixedly connected to the side of the water tank 4. A branch water pipe 609 is fixedly connected to the circumferential surface of one end of the water outlet pipe 608. One end of the branch water pipe 609 is fixedly connected to the side of the test chamber 3.

[0034] In some examples, the number of branch water pipes 609 is set to several, and the branch water pipes 609 are arranged in a circular array along the vertical central axis of the test chamber 3. The circular array of branch water pipes 609 can spray liquid onto the test seat 5 from multiple directions to simulate the impact of water flow at different angles, ensuring that all parts of the seat cover can be tested for waterproofing, avoiding partial omissions, and improving the comprehensiveness of the test.

[0035] There are two sliding plates 605 and sliding grooves 606, which are symmetrical about each other along the vertical central axis of the transmission ring 604. The symmetrically distributed sliding plates 605 and sliding grooves 606 provide bidirectional guidance for the transmission ring 604, balance the forces during shaking, prevent the transmission ring 604 from shifting or jamming, ensure the stability of the shaking trajectory of the test seat 5, and improve the consistency of the testing process.

[0036] Two leak-proof plates 610 are fixedly connected to the circumferential surface of the test chamber 3. The leak-proof plates 610 are located near the slide 606. The leak-proof plates 610 can block liquid that may seep out from the slide 606, prevent water from flowing out of the test chamber 3 and contaminating the device base 1 or other components, keep the equipment dry, reduce component damage caused by liquid corrosion, and extend the service life of the equipment.

[0037] The test chamber 3 has an observation window on its side, and the top of the water tank 4 is fixedly connected to a water inlet. The observation window allows for real-time observation of the water seepage of the seat cover during the test and timely recording of the test results.

[0038] For example, such as Figures 1-4 After the drive motor 602 starts, its output drives the active L-shaped transmission plate 603 to rotate, which in turn drives the driven L-shaped transmission plate 607 through the transmission ring 604. This causes the transmission ring 604 to slide back and forth along the slide groove 606 of the test chamber 3. The sliding plate 605 acts as a guide, thereby causing the test seat 5 to shake synchronously. At the same time, water in the water tank 4 is diverted through the outlet pipe 608 to the branch water pipes 609 in the circumferential array, spraying the test seat 5 from multiple angles. The anti-leakage plate 610 prevents water from seeping into the slide groove 606, simulating a waterproof test under dynamic usage scenarios of the seat.

[0039] like Figures 1-4 This illustration shows a waterproof testing device for genuine leather seat covers in another embodiment of the present invention, comprising: a recycling device 7, which includes a first recycling water pipe 701, one end of which is fixedly connected to the side of a water tank 4, and the other end of which is fixedly connected to a filter box 702. The bottom of the filter box 702 is fixedly connected to the top of the device base 1, and a second recycling water pipe 703 is fixedly connected to the side of the filter box 702. One end of the second recycling water pipe 703 is fixed... A filter screen 704 is snapped onto the inner wall side of the filter box 702 connected to the circumferential surface of the test box 3. A toothed gear 705 is fixedly connected to the circumferential surface of the output shaft of the drive motor 602. A rack box 706 is fixedly connected to the top of the device base 1. A spring 707 is fixedly connected to the bottom of the inner wall of the rack box 706. A reciprocating rack 708 is fixedly connected to one end of the spring 707. The reciprocating rack 708 meshes with the toothed gear 705. A cleaning brush 709 is fixedly connected to the side of the reciprocating rack 708.

[0040] In some examples, the side of the cleaning brush 709 contacts the side of the filter screen 704, and the diameter of the displacement trajectory of the cleaning brush 709 is equal to the diameter of the filter screen 704. The cleaning brush 709 makes full contact with the filter screen 704, and its trajectory covers the filter screen 704, effectively removing impurities from the filter screen, preventing clogging of the filter screen 704 from affecting water circulation efficiency, reducing the frequency of manual cleaning, and ensuring the continuous and stable operation of the recycling system.

[0041] A limiting groove is provided on the side of the rack and pinion box 706. The diameter of the limiting groove is equal to the diameter of the filter screen 704. One end of the cleaning brush 709 is slidably connected to the inner wall of the limiting groove. The limiting groove provides precise guidance for the cleaning brush 709, preventing it from shifting during reciprocating motion and ensuring that the cleaning brush 709 always fits in contact with the surface of the filter screen 704, thereby improving the stability and reliability of the cleaning effect.

[0042] There are two springs 707, which are symmetrical about each other along the vertical central axis of the reciprocating rack 708. The symmetrical springs 707 provide a balanced rebound force to the reciprocating rack 708, so that it can smoothly return to its original position after the toothed gear 705 disengages, reducing vibration and ensuring the regularity of the reciprocating motion of the cleaning brush 709.

[0043] A water level observation slot is provided on the side of water tank 4, and a filter screen observation slot is provided on the side of filter box 702. The water level observation slot facilitates monitoring of the water volume in water tank 4 and timely replenishment of water; the filter screen observation slot allows for a direct view of the degree of contamination of filter screen 704, facilitating timely replacement or cleaning, ensuring water circulation and filtration effectiveness, and improving equipment maintenance efficiency.

[0044] For example, such as Figures 1-4 Wastewater in test chamber 3 flows into filter chamber 702 via recycling pipe 703. After impurities are filtered out by filter screen 704, clean water flows back to water tank 4 via recycling pipe 701 for reuse. Drive motor 602 drives toothed gear 705 to rotate, which moves when it meshes with reciprocating rack 708, compressing spring 707. After disengagement, spring 707 returns to its original position, causing reciprocating rack 708 to move in the opposite direction, so that cleaning brush 709 cleans filter screen 704 along the limiting groove, preventing clogging. Water level and filter screen observation tank can monitor water volume and filter screen status in real time.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
