Description

Technical Field

[0001] This utility model relates to the field of electric heating foot pad technology, and in particular to a vehicle-mounted electric heating foot pad. Background Technology

[0002] Car electric heated floor mats are suitable for a variety of scenarios: On a cold winter morning, when the driver sits in the car and is exposed to the cold air, turning on the electric heating function will quickly spread warmth from the soles of the feet, dispelling the drowsiness after waking up; during long-distance driving, even if the wind is biting cold outside, it can keep the feet comfortable, avoid discomfort caused by low temperature, and relieve driving fatigue.

[0003] In some existing technologies, in-vehicle electrically heated floor mats achieve warmth by converting electrical energy into heat energy. Resistance wires or carbon crystal heating elements are embedded inside the mat. After being connected to the vehicle's power supply, current flows through the heating element, generating Joule heating. The heat is then evenly conducted to the surface of the mat through an insulating thermally conductive layer. A temperature control module monitors the temperature in real time and automatically cuts off power or reduces power when a set threshold is reached to prevent overheating.

[0004] However, in actual use, the non-removable design means that if the internal heating element malfunctions, it cannot be repaired or replaced individually and must be discarded as a whole, increasing the cost of use. Moreover, after long-term use, the heating performance of the floor mat material is affected by wear or aging, but the service life cannot be extended by replacing parts. In response to the above problems, a car electric heating floor mat is proposed. Utility Model Content

[0032] 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.

[0033] Reference Figures 1 to 3This utility model provides an embodiment of a vehicle-mounted electric heated floor mat, including a heated floor mat frame 1. The heated floor mat frame 1 serves as the supporting skeleton of the entire floor mat, providing an installation base for components such as the grid mesh 2 and the floor mat body 10. It also has good rigidity, can withstand the pressure of stepping without deformation, and ensures the overall stability of the floor mat. The grid mesh 2 is fixedly connected to both the upper and lower ends of the interior of the heated floor mat frame 1. The grid mesh 2 plays the role of supporting and protecting the floor mat body 10, dispersing the stepping pressure from above, and preventing the floor mat body 10 from being damaged due to uneven force. At the same time, its hollow structure helps air circulation, avoids the accumulation of moisture under the floor mat and the generation of odors, and can also assist in the uniform diffusion of heat from the heating mechanism. The floor mat body 10 is fixedly connected to the interior of the grid mesh 2. The floor mat body 10 is the part that directly contacts the feet of the driver and passengers, providing a comfortable stepping experience. At the same time, it works with the heating mechanism to transfer heat to the feet to achieve a warming function.

[0034] The four outer corners of the heated foot pad frame 1 are slidably connected to disassembly and assembly mechanisms. The foot pad body 10 contains a heating mechanism, which includes a foot pad surface layer 11. The foot pad surface layer 11 directly contacts the foot, providing a comfortable feel and protecting the underlying graphene heating film 12 from scratches by sharp objects. It also helps to evenly distribute heat to the foot. The outer surface layer 11 is fixedly connected to the inside of the foot pad body 10. The graphene heating film 12 is fixedly connected to the bottom outer end of the foot pad surface layer 11. The graphene heating film 12 is bonded to the foot pad surface layer 11 via a high-temperature resistant conductive adhesive. The graphene heating film 12 is firmly bonded to the heat insulation film 13. After the heating film is powered on, it utilizes the excellent electrical and thermal conductivity of graphene to evenly dissipate heat, providing a warm foot environment for drivers and passengers. Compared with traditional heating wires, it has the advantages of uniform heating, high efficiency, and long life. The heat insulation film 13 is fixedly connected to the bottom of the graphene heating film 12. The function of the heat insulation film 13 is to concentrate the heat generated by the graphene heating film 12 and conduct it upward to the surface layer 11 of the foot pad, preventing heat loss downward and improving heating efficiency. At the same time, it protects the car floor from high temperature and prevents the floor material from deforming or being damaged due to prolonged heating.

[0035] The disassembly and assembly mechanism includes a sliding latch 5. The outer surface of the sliding latch 5 is machined with two symmetrical spiral grooves to accommodate lubricating oil, ensuring smooth sliding of the sliding latch 5 during the sliding process of the hot foot pad frame 1. The sliding latch 5 is externally slidably connected to the four outer corners of the hot foot pad frame 1. The sliding latch 5 is externally fixedly connected to a limiting plate 7. The function of the limiting plate 7 is to limit the sliding stroke of the sliding latch 5, prevent it from sliding out of the hot foot pad frame 1, and at the same time play a stabilizing support role during the movement of the sliding latch 5, ensuring that the latch slides in a straight line, making the disassembly and assembly operation more precise and reliable. The top of the sliding latch 5 is fixedly connected to a cover 3.

[0036] During disassembly, the operator can unlock the sliding lever 5 by rotating or pressing the cover 3, thus enabling smooth disassembly. In addition, the cover 3 also serves a protective function, preventing dust and debris from entering the sliding structure inside the heated foot pad frame 1 and affecting the normal operation of the disassembly and assembly mechanism. The heated foot pad frame 1 has an internal elastic component, which includes a cavity 4. The cavity 4 provides installation space and motion guidance for the return spring 6, ensuring that the spring maintains coaxiality during compression and reset, guaranteeing the stability and reliability of the elastic component, and thus ensuring that the disassembly and assembly mechanism can achieve automatic reset function. The cavity 4 is located inside the heated foot pad frame 1, and the return spring 6 is installed on the outside of the cavity 4. When installing the foot pad, the sliding lever 5 is compressed, causing the return spring 6 to compress and store elastic potential energy. When the foot pad needs to be disassembled, after unlocking the sliding lever 5, the return spring 6 releases energy, pushing the sliding lever 5 to reset, so that the disassembly and assembly mechanism returns to its initial state for easy use next time, realizing the convenience and automation of foot pad disassembly and assembly.

[0037] Reference Figures 2 to 4 The graphene heating film 12 is externally fixedly connected to the inside of the floor mat body 10. The graphene heating film 12 is firmly bonded to the inside of the floor mat body 10 through high-temperature pressure-sensitive adhesive, forming a seamless connection. After being powered on, thanks to the excellent electrothermal conversion efficiency of graphene, it provides a warm and comfortable foot environment for drivers and passengers, and the heating is uniform, avoiding local overheating. The heat insulation film 13 is externally fixedly connected to the inside of the floor mat body 10. The four corners of the heated floor mat frame 1 are slidably connected to limit rods 8. After the floor mat is installed in place, the limit rods 8 and the sliding rods 5 engage to form a double locking mechanism to prevent the floor mat from... During vehicle operation, the device may loosen or shift due to external forces such as vibration and foot pressure. To ensure safety, the external limit lever 8 engages with the internal sliding lever 5. A booster 9 is fixedly connected to the external left rear end of the heated foot pad frame 1. The booster 9 is connected to the electrode circuit of the graphene heating film 12 via a waterproof quick-connect connector. It is installed on the external left rear end of the heated foot pad frame 1 and has multiple protection functions such as overvoltage, overcurrent, and short circuit. According to different ambient temperatures and user needs, it provides a stable and suitable working voltage for the graphene heating film 12, ensuring stable heating performance and extending the service life of the heating film.

[0038] A thermostat switch 14 is fixedly connected to the front left side of the heated foot pad frame 1. The thermostat switch 14 is connected to the booster 9 and the graphene heating film 12 via a waterproof cable. It is installed on the front left side of the heated foot pad frame 1 for easy operation by drivers and passengers. When the temperature reaches the set value, the output power of the booster 9 is automatically adjusted to achieve constant temperature control. When the temperature is abnormal, the power is immediately cut off and an audible and visual alarm is issued to ensure safety and improve energy efficiency. The sliding lever 5 is externally slidably connected to the inside of the cavity 4. The limiting plate 7 is externally slidably connected to the inside of the cavity 4. One end of the return spring 6 is fixedly connected to the inside of the cavity 4, and the other end of the return spring 6 is fixedly connected to the top of the limiting plate 7.

[0039] Working principle: When disassembling and assembling the foot pad body 10, by pulling the limiting lever 8, the limiting lever 8 is separated from the sliding lever 5. At this time, by pulling the cover 3, the cover 3 drives the limiting plate 7 to slide inside the cavity 4 through the sliding lever 5. Then, the limiting plate 7 can squeeze the return spring 6, causing the return spring 6 to deform. Then, the foot pad body 10 can be separated from the hot foot pad frame 1, and the foot pad body 10 can be taken out. When installing the foot pad body 10, by releasing the cover 3, the return spring 6 rebounds, and the foot pad body 10 can be locked inside the hot foot pad frame 1. By inserting the limiting lever 8, the limiting lever 8 is locked with the sliding lever 5, and the foot pad body 10 can be installed.

[0040] The heating system uses a graphene heating film 12 as the core heating element. The graphene heating film 12, with its high electrothermal conversion efficiency, uniform heating, and thin and flexible characteristics, is suitable for scenarios requiring high heating precision and installation flexibility. The booster 9, as the power control center, adjusts the transformer turns ratio based on the different power requirements of the two heating elements using the principle of electromagnetic induction, precisely regulating the output voltage and current to ensure stable operation of the heating elements at rated power. The temperature controller switch 14 adopts an electronic structure, monitoring the temperature in real time. When preset upper and lower limits are reached, it automatically controls the circuit to maintain temperature stability. The fuse, as a safety feature, melts due to excessive current in the event of circuit overload or short circuit, cutting off the circuit and preventing equipment damage and accidents.

[0041] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
