Description

Technical Field

[0001] This utility model relates to the field of automotive floor mat technology, and in particular to a heated automotive floor mat that is easy to inspect and maintain. Background Technology

[0002] During daily use of a car, car floor mats are an important interior component, mainly serving to protect the car floor, prevent stains from remaining, and improve foot comfort. Currently, there are many types of car floor mats on the market, which can be divided into rubber floor mats, leather floor mats, and fabric floor mats according to materials. Their designs mostly focus on anti-slip, wear-resistant, and easy-to-clean properties.

[0003] In the prior art, some floor mats have a flexible heating element integrated into the internal interlayer. The heating element is connected to the power interface inside the car through a wire to form a power supply circuit. When the user turns on the heating switch, electrical energy is transmitted to the heating element through the wire. The heating element converts the electrical energy into heat energy and distributes it evenly, causing the temperature of the floor mat to gradually rise.

[0004] However, in actual use, when the heating element malfunctions, it cannot be disassembled and removed, making it difficult for repair personnel to inspect or replace the heating element separately. In this case, the entire floor mat may need to be replaced, and floor mats with heating functions are usually expensive, which will significantly increase the repair cost. Even if the fault is minor and only a small part of the heating element needs to be repaired, it cannot be operated because it cannot be removed, and the whole thing must be dealt with, resulting in waste. In response to the above problems, a car heated floor mat that is easy to inspect and repair is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a car heated floor mat that is easy to inspect and repair, aiming to improve the problem that some existing car heated floor mats that are easy to inspect and repair cannot remove the heating element by disassembling the upper and lower floor mats.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A car heated floor mat that is easy to maintain includes an upper floor mat, a lower floor mat fixedly connected to the bottom of the upper floor mat, a locking mechanism slidably connected to the four outer corners of the lower floor mat, an anti-tear mechanism inside the lower floor mat, a water channel on the outside of the upper floor mat, and a heating tube fixedly connected to the outside of the lower floor mat.

[0008] The clamping mechanism includes a sliding clamp rod, which is slidably connected to the outside of the lower foot pad.

[0031] 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.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a car heated floor mat that is easy to maintain. It includes an upper floor mat 1, which is the part that directly contacts the feet of the driver and passengers. It is made of soft, wear-resistant materials such as fleece, leather, or composite fabric. A lower floor mat 2 is fixedly connected to the bottom of the upper floor mat 1. The main function of the lower floor mat 2 is to enhance the shape stability of the entire floor mat and prevent deformation due to stress during use. Each of the four outer corners of the lower floor mat 2 is slidably connected to a locking mechanism. The lower floor mat 2 has an internal tear-resistant mechanism, including a waterproof layer 11, which prevents liquid penetration. When beverages, water, or other liquids are accidentally spilled inside the car, the waterproof layer 11 can repel the liquid. The waterproof layer 11 acts as a barrier between the upper floor mat 1 and the waterproof layer 11, preventing liquid from seeping into the lower floor mat 2 and the car floor, thus avoiding moisture, mold, and rust on the car floor. It also facilitates the cleaning of spilled liquid. The waterproof layer 11 is externally fixed to the inside of the lower floor mat 2, and a reinforcing layer 12 is fixedly connected to the bottom of the waterproof layer 11. The reinforcing layer 12 has high tensile strength and toughness, which can enhance the overall structural strength of the tear-resistant mechanism. When the floor mat is pulled by external force, the reinforcing layer 12 can distribute the force and reduce local stress concentration, thereby reducing the risk of the floor mat being torn. At the same time, it can also provide support for the waterproof layer 11 and prevent the waterproof layer 11 from being damaged due to excessive force.

[0033] A tear-resistant layer 13 is fixedly connected to the bottom of the reinforcing layer 12. The tear-resistant layer 13 is the core protective layer of the tear-resistant mechanism, directly bearing the friction and tensile forces from the outside. It effectively resists the risk of tearing caused by scratches from sharp objects and heavy foot pressure, further improving the overall tear resistance of the floor mat and ensuring that the floor mat remains intact after long-term use. The outer surface of the reinforcing layer 12 is located inside the lower floor mat 2, and the outer surface of the tear-resistant layer 13 is located inside the lower floor mat 2. A water channel 10 is provided on the outer surface of the upper floor mat 1 to guide liquid flow. When liquid inside the vehicle spills onto the surface of the upper floor mat 1, it is channeled... The water trough 10 can collect liquids together, preventing them from flowing randomly on the surface of the floor mats and making them easy to clean. At the same time, the water trough 10 can also increase the friction on the surface of the upper floor mat 1, further improving the anti-slip effect. The lower floor mat 2 is externally fixedly connected to a heating tube 3, which is connected to the car's power supply. When powered on, it can generate heat and transfer the heat to the upper floor mat 1 and the surrounding environment through heat conduction, thereby providing warmth to the feet of drivers and passengers in cold weather and improving the comfort of the car. At the same time, the flexible design of the heating tube 3 allows it to adapt to the shape changes of the floor mats without affecting the installation and use of the floor mats.

[0034] The clamping mechanism includes a sliding lever 5, which can slide flexibly when subjected to force. By engaging with the fixing holes on the car floor through the clamping head, the floor mat and the floor can be quickly clamped together. It is also easy to disassemble and replace. The sliding lever 5 is externally slidably connected to the outside of the lower floor mat 2. The four outer corners of the upper floor mat 1 are fixedly connected with connecting rods 4, which enhances the firmness of the connection between the upper floor mat 1 and the lower floor mat 2, prevents the corners from separating during stepping, and supports the four corners of the floor mat to prevent the corners from collapsing and deforming after long-term use, thus maintaining the overall flatness of the floor mat. The lower floor mat 2 has a limiting elastic component inside. The limiting elastic component includes a cavity 6. The depth of the cavity 6 is designed according to the extension stroke of the sliding lever 5, which ensures that the sliding lever 5 has enough extension length to achieve clamping, and can fully accommodate the limiting plate 7 and the spring when retracted, making the structure more compact. The cavity 6 is externally opened at the four outer corners of the lower floor mat 2, and the limiting plate 7 is externally slidably connected to the inside of the cavity 6.

[0035] A return spring 8 is sleeved on the outside of the sliding lever 5. When the sliding lever 5 is pressed and retracted, the return spring 8 is further compressed and stores elastic potential energy. When the external force disappears, the spring releases its potential energy and pushes the limiting plate 7 and the sliding lever 5 outward, so that the sliding lever 5 automatically returns to the clamping position, ensuring that the clamping mechanism always maintains an effective clamping state without manual adjustment. The limiting elastic component is internally slidably connected to the limiting plate 7. The limiting plate 7 always maintains contact with the inner wall of the cavity 6 during the sliding process. It can transmit the elastic force of the return spring 8 and disperse the force through its own planar structure, preventing the sliding lever 5 from bending and deforming due to uneven force. The limiting plate 7 is externally fixedly connected to the outside of the sliding lever 5, and the outside of the sliding lever 5 is slidably connected to the inside of the cavity 6.

[0036] Reference Figures 3 to 5 A controller 9 is fixedly connected to the outer right side of the upper foot pad 1. The controller 9 can adjust the heating temperature, and usually has multiple temperature levels for users to choose from to adapt to different levels of cold and individual needs. It can also control the start and stop of heating. Users can turn the heating function on or off at any time according to the actual situation to avoid energy waste. In addition, some controllers 9 also have an overheat protection function. When the temperature of the heating tube 3 or the foot pad is detected to be too high, the power will be automatically cut off to prevent safety hazards caused by overheating and ensure safe use. The controller 9 is fixedly connected to the inside of the lower foot pad 2. One end of the return spring 8 is fixedly connected to the inside of the cavity 6, and the other end of the return spring 8 is fixedly connected to the outside of the limiting plate 7. When the sliding lever 5 is pressed and retracted, the limiting plate 7 moves into the cavity 6, and the return spring 8 is compressed and stores elastic potential energy. When the pressing force is removed, the return spring 8 releases the elastic potential energy, pushes the limiting plate 7 to move out of the cavity 6, and then drives the sliding lever 5 to extend and return to the locked position.

[0037] Working principle: When disassembling and assembling the heating tube 3, by pulling the sliding latch 5, the sliding latch 5 causes the limiting plate 7 to slide inside the cavity 6, which in turn causes the limiting plate 7 to press the return spring 8, thereby separating the sliding latch 5 from the connecting rod 4, allowing the connecting rod 4 to be pulled out, separating the upper foot pad 1 from the lower foot pad 2, and then removing the heating tube 3. When installing the heating tube 3, by placing the heating tube 3 inside the lower foot pad 2, and then inserting the connecting rod 4 inside the upper foot pad 1 and the lower foot pad 2, the sliding latch 5 is released, causing the return spring 8 to rebound, thereby locking the sliding latch 5 and the connecting rod 4 together, thus fixing the heating tube 3.

[0038] The waterproof layer 11 is made of high-density PVC material. Its tight molecular structure blocks liquid penetration, preventing rainwater, spilled beverages, and other liquids from entering the footpad and damaging the heating element. It provides basic protection for the heating system. The reinforcing layer 12 is made of high-strength non-woven fabric. Its crisscrossing fiber structure enhances the overall rigidity of the footpad, preventing deformation caused by temperature changes during heating. It also distributes the pressure of stepping on the foot and protects the heating circuit underneath. The tear-resistant layer 13 is made of Kevlar fiber. With its high tensile strength and abrasion resistance, it resists external impacts such as friction from the sole of the shoe and scratches from sharp objects, extending the life of the footpad. When the three layers are used together, the waterproof layer 11, as the outermost layer, directly faces liquid intrusion. The reinforcing layer 12, located in the middle layer, connects the upper and lower structures and enhances the stability of the shape. The tear-resistant layer 13 is tightly attached to the outer layer of the heating module to form a physical barrier. The three layers work together to ensure the safe and stable operation of the heating function and improve the durability of the footpad through layered protection.
