Description

Technical Field

[0001] This utility model belongs to the field of automotive interior technology, specifically relating to a heated armrest for automotive interiors with a knob adjustment. Background Technology

[0002] Existing armrest heating designs generally fall into three categories: 1. Uncovered pure injection molded parts are heated by heating wires; 2. Armrest assemblies with covers are heated on one side by electric heating pads; 3. The armrest is heated by the input of the car's air conditioning ventilation and heating system.

[0003] The existing handrail heating design has the following drawbacks: heating pure plastic parts may lead to localized overheating or uneven temperature due to the limited arrangement of heating wires, affecting comfort; electric heating pads only heat one side, which may result in significant temperature differences on the hand contact surface, affecting user experience; and the heating efficiency of radiators is not high, requiring a long wait for the temperature to rise, and also leading to uneven temperature in the heating area.

[0004] Secondly, most existing handrail heating systems are controlled by temperature sensors, lacking adjustment or even a switch function next to the handrail, which reduces the user's autonomy.

[0005] The information disclosed in the above background section is only intended to enhance the understanding of the overall background of this utility model, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this utility model is to provide a heated armrest for automotive interiors with a knob adjustment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rotary-adjustable heated armrest for automotive interiors includes an armrest frame, a switch panel mounted on the front end of the armrest frame, an armrest sponge mounted on the rear end of the armrest frame, an armrest covering skin that wraps the armrest sponge around the armrest frame, and an electric window lift switch mounted on the switch panel. Heating wires are also provided within the armrest frame, and heating pads are provided between the armrest sponge and the armrest covering skin. A temperature adjustment knob is also provided on the switch panel. The heating wires and heating pads are connected to the vehicle's power supply via wires, a thermostat, and the temperature adjustment knob, and the temperature is manually adjusted.

[0009] Specifically, the armrest frame is provided with a screw seat facing the side and a first buckle seat for connecting with the door panel, and the heating wire is wavy and fastened between the screw seat and the first buckle seat.

[0010] Specifically, the front end of the handrail frame is provided with a second buckle seat facing upwards, and the switch panel is fixed to the second buckle seat by buckles.

[0011] Specifically, a matching groove is provided at the rear end of the armrest frame, and the armrest sponge is fixed to the matching groove.

[0012] Specifically, the heating pad is fixed to the armrest sponge by adhesive.

[0013] Specifically, the handrail covering is bonded to the handrail frame with adhesive.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This solution proposes a device that heats both the top and sides of the armrest. By placing the heating pad on the foam, the overall appearance of the armrest is not damaged. Other areas are heated by heating wires. While ensuring comprehensive and rapid heating, there is no temperature difference in the heated areas. It also takes into account the feel of the covering and the comfort of the heating function. The design is reasonable and the structure is compact.

[0021] To explain the technical content, objectives, and effects of this utility model in detail, the following description is provided in conjunction with embodiments and accompanying drawings. In the description of these embodiments, it should be understood that terms indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this embodiment and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] The technical solution adopted in this embodiment is a heated armrest for automotive interiors that is adjusted by a knob, such as... Figure 1-3 As shown, the main components include an electric window lift switch 2, a switch panel 3, a handrail covering 4, a handrail frame 5, and handrail foam 8. The electric window lift switch 2 is installed on the switch panel 3 for adjusting the window height; the switch panel 3 is fixed to the second clip seat 11 of the handrail frame 5 using iron clips and welding; the handrail covering 4 is bonded to the handrail frame 5 using adhesive, vacuum adsorption, or other processes; the handrail frame 5 is installed on the door panel using screws and iron clips; and the foam 8 is fixed to the matching groove 12 of the handrail frame 5.

[0023] The key point of this embodiment is:

[0024] A heating wire 7 is installed inside the armrest frame 5, and a heating pad 6 is installed between the armrest sponge 8 and the armrest covering skin 4. A temperature adjustment knob 1 is also installed on the switch panel 3. The heating wire 7 and the heating pad 6 are connected to the vehicle power supply through wires via the thermostat and the temperature adjustment knob 1. The temperature adjustment knob 1 has an on / off switch and two temperature adjustment modes. The heating temperature of the armrest can be adjusted by manually adjusting the temperature adjustment knob 1.

[0025] The key feature of this invention is the achievement of full heating of the covered armrest and the addition of a temperature adjustment button 1. Heating is achieved using heating pads 6 for the foam-covered portion of the armrest, and metal heating wires 7 for the non-foam-covered portion. In use, the heating wires 7 and heating pads 6 are energized and heated when the temperature adjustment knob 1 is turned to the corresponding setting. The heating wires 7 are located inside the armrest frame 5, raising the overall temperature of the armrest through heat conduction, thus providing insulation. The heating pads 6 are located between the armrest foam and the covered surface, directly transferring heat to the surface for rapid heating. The heating area is differentiated according to the internal structure of the armrest cover, resulting in uniform and rapid heating without uneven temperature distribution. A temperature controller monitors temperature changes in real time to ensure stable heating and prevent overheating. The advantages of this embodiment are that the temperature can be freely adjusted, the armrest is not heated on one side, and the heating area is uniform and rapid.

[0026] As a preferred technical solution in this embodiment, such as Figure 3As shown, the armrest frame 5 is provided with a screw seat 9 facing to the side for connection with the door panel and a first buckle seat 10. The heating wire 7 is wavy and secured between the screw seat 9 and the first buckle seat 10. The wavy structure allows the heating wire to be more widely distributed within the armrest frame 5. Compared with a straight arrangement, the heating area is increased, avoiding local overheating or uneven temperature, thus improving heating effect and comfort. Moreover, the wavy structure increases the contact points of the heating wire. The securing method using the screw seat 9 and the first buckle seat 10 makes it more firmly fixed within the armrest frame 5, preventing loosening or displacement due to vibration during vehicle operation or pressure during armrest use, thereby improving service life and safety.

[0027] Although the present invention has been described in detail above with specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
