Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive front door guard plate technology, and in particular to an automotive front door guard plate assembly. Background Technology
[0002] As an important component of automotive interiors, the front door trim assembly is mainly installed on the inside of the door sheet metal. It serves multiple functions, including protecting the door structure, improving driving comfort, and enhancing aesthetics. It typically integrates various functional modules such as storage space, armrests, and audio components. At the same time, it needs to meet multiple requirements such as lightweighting, NVH performance, and ergonomics, directly affecting the overall quality of the vehicle and the user experience.
[0003] Early automotive front door skid plate assemblies used a single rigid plastic material with a simple structure, fixed to the door sheet metal only by screws. This design had significant shortcomings: firstly, it lacked protection against external elements such as water stains and dust; secondly, the assembly process was cumbersome, and repair and replacement were inconvenient. With technological advancements, existing skid plate assemblies have been improved through optimized structural design and material application. They employ a snap-on quick-installation structure to reduce assembly time, use sound-absorbing cotton lining to improve sound insulation, and cover the surface with soft materials to improve tactile feel. However, existing skid plate assemblies still have limitations in dealing with rain... There are still shortcomings in natural environments: Although drainage holes are set at the bottom of the doors to drain accumulated water, they cannot effectively absorb and drain water stains remaining above the glass windows. The existing protective panels and door glass are usually only sealed by a simple sealing strip. After rainwater seeps in, the water stains will flow along the inside of the glass to the surface of the protective panel. Since the protective panel lacks a targeted water guiding and water absorption structure, the water stains will remain on the surface of the protective panel, which not only affects the appearance of the interior, but also causes the protective panel material to mold and deform in the long term, and even seep into the inside of the door, affecting the normal operation of the door lock and window regulator components. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figure 1 , Figure 3 and Figure 7 An embodiment of this utility model provides: a car front door guard plate assembly, including a door panel 1, a water absorption and discharge mechanism 2 provided on the rear side of the door panel 1, an inclined protrusion 4 fixedly connected to the middle of the front side of the door panel 1, a hidden storage mechanism 3 provided on the top right side of the inclined protrusion 4, a locking component 5 provided at the top front side of the door panel 1 for controlling the opening of the car door, an auxiliary component 6 provided on the top left side of the inclined protrusion 4, an audio component 7 provided on the front left side of the door panel 1 for protecting the audio system, and a storage component 8 provided at the bottom front end of the door panel 1.
[0035] The water absorption and discharge mechanism 2 includes a limiting baffle 201. The left and right sides of the limiting baffle 201 are fixedly connected to the rear side of the inner wall of the door panel 1. A water-absorbing adhesive plate 202 is fixedly connected to the front side of the limiting baffle 201. A hollow collecting block 203 is fixedly connected to the bottom front end of the limiting baffle 201. The limiting baffle 201 can provide support and limit the water-absorbing adhesive plate 202 and the hollow collecting block 203 above. At this time, the water-absorbing adhesive plate 202 will absorb the incoming water stains, and the absorbed water will accumulate on its surface. Thus, the weight of the accumulated water stains is greater than the weight of the water stains on the water-absorbing adhesive plate 202 and the car window glass. When the water adheres to the glass surface, it flows into the hollow collection block 203 below. The bottom end of the hollow collection block 203 is connected to a drain pipe 204. The bottom end of the outer wall of the drain pipe 204 penetrates the bottom end of the door panel 1. A one-way water valve 205 is fixedly connected to the middle of the outer wall of the drain pipe 204. The water stains that enter the hollow collection block 203 will be discharged into the door panel 1 through the drain pipe 204 and the one-way water valve 205 above. A window groove 206 is opened at the top of the door panel 1. Rainwater flows in along the window groove 206, or when the car window is lowered, the water stuck to the top of the car window will fall down along the window groove 206.
[0036] Specifically, during rainy weather, rainwater flows in along the window groove 206, or when the car window is lowered, the water adhering to the top of the window will descend along the window groove 206. At this time, the water-absorbing adhesive plate 202 will absorb the incoming water stains, and the absorbed water will accumulate on its surface. When the weight of the accumulated water stains is greater than the adsorption force between the water-absorbing adhesive plate 202 and the car window glass surface, it will flow into the hollow collection block 203 below. The limiting baffle 201 can provide support and limit for the water-absorbing adhesive plate 202 and the hollow collection block 203 above, ensuring the drainage of water stains. The water stains entering the hollow collection block 203 will be discharged into the door panel 1 through the drain pipe 204 and the one-way water valve 205 above. The one-way water valve 205 can prevent external liquids or dust impurities from entering the interior of the door panel 1 through the drain pipe 204, causing internal pollution, thereby preventing water stains from not being discharged from the door panel 1 in time.
[0037] Reference Figure 4 , Figure 5 and Figure 6The concealed storage mechanism 3 includes a storage groove 301. The outer wall of the storage groove 301 is opened on the top right side of the inclined protruding plate 4. The top of the inner wall of the storage groove 301 is rotatably connected to a buffer pad 302. Rotating the buffer pad 302 allows a gap to be opened above the storage groove 301, so that smaller and more valuable items can be placed in the storage groove 301. The front right side of the door panel 1 has a notch 303. The inner wall of the notch 303 is slidably connected to a locking plate 304. The rear side of the locking plate 304 is fixedly connected to a return spring 305. The rear side of the buffer pad 302 has a slot 306. By pressing the locking plate 304, the locking plate 304 squeezes the return spring 305, and at the same time, the locking plate 304 is disengaged from the slot 306 above the buffer pad 302.
[0038] Specifically, when placing smaller, valuable items, pressing the latch 304 causes it to compress the return spring 305, simultaneously disengaging the latch 304 from the slot 306 above the buffer pad 302. Rotating the buffer pad 302 then creates a gap above the storage recess 301, allowing smaller, valuable items to be placed there. Reversing the rotation of the buffer pad 302 and releasing the pressure on the latch 304 releases the elastic potential energy of the return spring 305, causing the latch 304 to re-engage with the slot 306 above the buffer pad 302, thus achieving concealed storage of small, valuable items and enhancing the protection of valuables inside the vehicle.
[0039] Reference Figure 1 , Figure 2 and Figure 5The locking assembly 5 includes a protective frame 501, the rear side of which is fixedly connected to the front top of the door panel 1. The protective frame 501 provides protection for the rotating block 502. The rotating block 502 is rotatably connected to the inner wall of the protective frame 501, and the rotating block 502 facilitates the unlocking of the car door, thereby facilitating the opening of the car door. The auxiliary assembly 6 includes multiple window lift switches 601, which control the raising and lowering of the car windows in the door. The outer walls of the multiple window lift switches 601 are rotatably connected to the top left side of the inclined protrusion 4. A concave hand groove 602 is provided in the middle of the top of the inclined protrusion 4, which facilitates the opening of the car door. External force is applied to open the car door; the audio component 7 includes a limiting ring 701, the rear side of which is fixedly connected to the front left side of the door panel 1. The limiting ring 701 provides installation space for the honeycomb plate 702 and the subsequently installed audio equipment. The honeycomb plate 702 is fixedly connected to the front side of the inner wall of the limiting ring 701, and the honeycomb plate 702 provides protection for the audio equipment; the storage component 8 includes an expansion groove 801, the outer wall of which is opened at the front bottom of the door panel 1. The expansion groove 801 can increase the bottom space of the door panel 1. An arc plate 802 is fixedly connected to the front side of the expansion groove 801, and the arc plate 802 can prevent items placed inside from falling out;
[0040] Specifically, the protective frame 501 provides protection for the rotating block 502, and the rotating block 502 facilitates the unlocking of the car door, thereby facilitating the opening of the car door. The window lift switch 601 controls the raising and lowering of the car window in the car door. At the same time, the concave hand groove 602 facilitates the application of external force to open the car door. The limiting ring 701 provides installation space for the honeycomb plate 702 and the subsequently installed audio system. The honeycomb plate 702 also provides protection for the audio system. The expansion groove 801 increases the bottom space of the door panel 1, and the arc plate 802 prevents items placed inside from falling out.
[0041] Reference Figure 1 , Figure 6 and Figure 7 The inner wall dimensions of the window recess 206 are the same as those of the hollow collection block 203, so that rainwater flowing in from the window recess 206 can flow precisely into the hollow collection block 203. The front side of the hollow collection block 203 is fixedly connected to the front side of the inner wall of the door panel 1, ensuring that the hollow collection block 203 is stably positioned in the entire water absorption and discharge mechanism 2. The front side of the outer wall of the card plate 304 penetrates the front side of the door panel 1, allowing the card plate 304 to be operated directly from the outside of the door panel 1, which facilitates the control of the opening and closing state of the concealed storage mechanism 3. The front end of the outer wall of the card plate 304 engages with the inner wall of the card groove 306, forming a reliable locking structure.
[0042] Specifically, the inner wall size of the window recess 206 is the same as the inner wall size of the hollow collection block 203, allowing rainwater flowing in from the window recess 206 to flow into the hollow collection block 203 without obstruction and precisely, thanks to the guide channel formed by the consistent size of the two. This avoids water dispersion and overflow due to size differences. The front side of the hollow collection block 203 is fixedly connected to the front side of the inner wall of the door panel 1, ensuring that the hollow collection block 203 is stable in the entire water absorption and discharge mechanism 2. During the process of receiving water flowing down from the water absorption plate 202 and draining water in conjunction with the drain pipe 204, it will not be affected by vibrations during vehicle movement. The front side of the outer wall of the card plate 304 penetrates the front side of the door panel 1, allowing the card plate 304 to be operated directly from the outside of the door panel 1, facilitating the control of the opening and closing state of the concealed storage mechanism 3. The front end of the outer wall of the card plate 304 engages with the inner wall of the card slot 306, forming a reliable locking structure.
[0043] Working principle: First, during rainfall, rainwater will flow in along the window groove 206, or when the window is lowered, water droplets above the window will slide down along the window groove 206. At this time, the water-absorbing rubber plate 202 will absorb this water and form water stains on the surface. When the weight of the accumulated water stains exceeds the adsorption force between the water-absorbing rubber plate 202 and the window glass surface, the water stains will flow into the hollow collection block 203 below. The limiting baffle 201 provides necessary support and limiting for the water-absorbing rubber plate 202 and the hollow collection block 203 to ensure that the water can be drained smoothly. The water flowing into the hollow collection block 203 will be discharged to the outside of the door panel 1 through the drain pipe 204 and the one-way water valve 205 above. The function of the one-way water valve 205 is to prevent external liquids and dust impurities from entering the interior of the door panel 1 through the drain pipe 204, thereby avoiding internal pollution and ensuring that water can be discharged from the door panel 1 in a timely manner.
[0044] Furthermore, through the concealed storage mechanism 3, when storing small valuable items, the operator needs to press the card plate 304 to compress the return spring 305 and simultaneously release the locking state between the card plate 304 and the card slot 306 on the buffer pad 302. Then, rotate the buffer pad 302 to form an opening above the storage groove 301, making it easy to place small valuable items. Afterward, rotate the buffer pad 302 in the opposite direction and release the pressing force on the card plate 304, causing the return spring 305 to release its stored elastic potential energy and push the card plate 304 to re-lock with the card slot 306 on the buffer pad 302, thereby achieving concealed storage of small valuable items and enhancing the security protection of valuable items in the vehicle.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
