[0026] With the development of science and technology, people have put forward higher requirements for the riding comfort performance of automotive products. At present, as an automotive accessory installed between two seats, the armrest of a vehicle is often used for the driver to place their arm, thus improving the comfort of the driver during long drives.
[0027] However, when designing the armrest of a vehicle, the comfort in terms of temperature is often overlooked. For example, when the temperature is relatively high in summer, if the armrest can lower its own temperature, it can bring a more comfortable experience to the driver.
[0028] Please refer to Figure 1 and Figure 2 To solve the problem that it is difficult to achieve refrigeration for the existing vehicle armrest, resulting in poor comfort of the armrest, the present application provides an armrest assembly 100.
[0029] Specifically, the armrest assembly 100 provided in the present application includes an armrest box (not shown in the figure), an armrest unit 10, and a refrigeration module 20. The refrigeration module 20 is installed in the armrest box. The armrest unit 10 is installed on the armrest box. The armrest unit 10 includes an armrest skeleton 11, a foam layer 12, an outer covering layer 13, and a conduction sheet 14. The foam layer 12 and the outer covering layer 13 are provided on one side of the armrest skeleton 11, and the outer covering layer 13 covers the outer periphery of the foam layer 12 and is installed on the armrest skeleton 11 through the foam layer 12. Among them, the conduction sheet 14 is provided on the surface of the foam layer 12 close to the outer covering layer 13, and the conduction sheet 14 is thermally conductively connected to the outer covering layer 13 and the refrigeration module 20 respectively.
[0030] It can be understood that the occupant's arm often abuts against the outer surface of the outer covering layer 13. By providing the conduction sheet 14 and the refrigeration module 20 in the present application, the cold generated by the refrigeration module 20 can be transmitted to the conduction sheet 14 and then through the conduction sheet 14 to the outer surface of the outer covering layer 13 through the outer covering layer 13, thereby reducing the temperature of the outer surface of the outer covering layer 13 and greatly improving the comfort of the occupant. At the same time, since the conduction sheet 14 in the present application uses a contact method to transfer cold, it is possible to avoid opening holes in the outer covering layer 13, thus effectively ensuring the appearance quality of the armrest assembly 100.
[0031] In one embodiment, the foam layer 12 is configured as a polyurethane layer. The polyurethane material has a certain elasticity, and the foam layer 12 formed by processing polyurethane is softer and more comfortable, which can effectively improve comfort and safety.
[0032] Furthermore, the foam layer 12 is formed by foaming. In this way, the foam layer 12 is relatively light, and both installation and disassembly are very convenient, and it has the advantages of sound absorption, waterproof, anti-corrosion, and low pollution.
[0033] However, it is not limited to this. In other embodiments, the foam layer 12 can also be formed by processing other plastics or rubbers, as long as the same effect can be achieved.
[0034] In one embodiment, the conduction sheet 14 and the foam layer 12 are integrally embedded and formed structures. That is, when the foam layer 12 is foamed and formed, the connection between the conduction sheet 14 and the foam layer 12 is realized synchronously, effectively ensuring the connection strength between the conduction sheet 14 and the foam layer 12 and ensuring the reliability of the connection of the conduction sheet 14.
[0035] Among them, the conduction sheet 14 is preferably disposed in the middle of the surface of the foam layer 12 close to the outer covering layer 13 to improve the uniformity of the temperature reduction of the outer covering layer 13, thereby improving the comfort of the armrest unit 10.
[0036] Furthermore, in one embodiment, the conduction sheet 14 can be configured as a copper sheet or an aluminum sheet. Both copper and aluminum have good thermal conductivity and can transfer the cold generated by the refrigeration module 20 to the outer covering layer 13 better, reducing the loss of cold.
[0037] In one embodiment, the refrigeration module 20 is configured as a thermoelectric cooler. Since the lowest temperature of thermoelectric cooling is usually around 5°C and will not reach below 0°C, when the temperature of the car armrest is reduced by thermoelectric cooling, the temperature of the armrest unit 10 can be better adjusted to the temperature comfort range of the occupant, effectively improving the comfort of the occupant. Among them, the thermoelectric cooler can be attached to the inside of the armrest box so that the armrest box forms a refrigerator with a refrigeration function. In this way, the drinks and the like placed inside can be refrigerated, further meeting the needs of the occupant.
[0038] In addition, due to the Peltier effect of the thermoelectric cooler, that is, the direction of the current flowing through the thermoelectric cooler can be changed to make it release heat. In this way, the heating of the armrest unit 10 can be realized, improving the comfort in low-temperature environments such as winter.
[0039] In one embodiment, as Figure 1 shown, the armrest skeleton 11 includes a main body portion 111 and an edge portion 112 that surrounds at least a part of the circumference of the main body portion 111. The edge portion 112 and the main body portion 111 enclose an installation groove 1101, and one end of the foam layer 12 is inserted into the installation groove 1101. The armrest skeleton 11, as the support structure of the armrest unit 10, can be processed from materials such as plastics or metals with a certain strength.
[0040] It can be understood that by enclosing the installation groove 1101 with the main body portion 111 and the edge portion 112 on the armrest skeleton 11, the foam layer 12 can be limited by the installation groove 1101, which is beneficial to the installation of the foam layer 12.
[0041] To further improve the connection efficiency between the foaming layer 12 and the armrest frame 11, a positioning post (not shown in the figure) may be provided on one of the foaming layer 12 and the armrest frame 11, and a positioning hole (not shown in the figure) may be provided on the other. Exemplarily, when the positioning post is provided on the foaming layer 12 and the positioning hole is provided on the armrest frame 11, the positioning post is preferably provided at one end of the foaming layer 12 inserted into the installation groove 1101. At this time, the positioning hole is correspondingly provided in the installation groove 1101. Vice versa, and the details will not be elaborated here.
[0042] In one embodiment, the armrest frame 11 further includes a reinforcing rib (not shown in the figure), and the reinforcing rib is located on the side of the main body portion 111 away from the foaming layer 12. In this way, the structural strength of the armrest frame 11 can be further improved. Of course, to ensure the connection strength between the main body portion 111 and the edge portion 112, a reinforcing rib may also be provided in the installation groove 1101.
[0043] This application also provides a sub-instrument panel, which includes a control module 200 and the armrest assembly 100 of any one of the above embodiments. The control module 200 is used to control the temperature of the refrigeration module 20. In this way, it is convenient to control the refrigeration temperature of the refrigeration module 20, and further improve the refrigeration comfort of the armrest assembly 100.
[0044] Furthermore, as Figure 2 shown, the sub-instrument panel further includes an operation screen 300. The operation screen 300 is signal-connected to the control module 200. By providing the operation screen 300, it is convenient for the occupant to input a refrigeration instruction.
[0045] Specifically, when the occupant inputs a corresponding refrigeration instruction on the operation screen 300, the controller can receive the refrigeration instruction and transmit it to the refrigeration module 20 to implement the temperature adjustment function.
[0046] This application also provides a vehicle, which includes the above-mentioned sub-instrument panel.
[0047] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0048] The above-described embodiments only represent several implementation manners of this application. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the patent protection scope of this application should be subject to the appended claims.
