Description

Technical Field

[0001] This utility model relates to a car seat heating structure. Background Technology

[0002] In the prior art, there are automotive seat heating structures with seat heaters embedded in the seat cushion. These seat heaters utilize a resistive element that converts electrical energy into heat energy and are powered by the vehicle's battery.

[0003] Such car seat heating structures require dedicated seat heaters, which increases equipment costs and leads to higher operating costs due to lower energy conversion efficiency. In particular, in the case of electric vehicles, using the vehicle's battery to power the seat heaters reduces the vehicle's driving range. Utility Model Content

[0004] In view of the above situation, the purpose of this utility model is to provide a car seat heating structure that can achieve seat heating at a lower cost.

[0005] As a technical solution to the above-mentioned technical problems, this utility model provides a car seat heating structure, characterized in that: an equipment box containing multiple vehicle-mounted devices that generate heat during car operation is configured under the car seat; and a heat-conducting pipe communicating with the equipment box is embedded inside the seat cushion.

[0006] The advantages of the above-mentioned car seat heating structure of this utility model are: it can utilize the heat generated by the existing on-board equipment used in the car to heat the seat cushion. Specifically, the heat generated by the on-board equipment can raise the temperature of the air inside the equipment box. The heated air flows into the heat-conducting pipe and is released into the seat cushion through the heat-conducting pipe, thereby heating the seat cushion.

[0007] Since there is no need to use a dedicated heater to heat the seats, equipment costs can be reduced. Furthermore, since no energy conversion is required, and heating is provided solely using the heat generated by existing onboard equipment, energy savings and reduced operating costs are achieved.

[0008] In particular, in the case of electric vehicles, the driving range will not be shortened because there is no need to power the seat heaters with onboard batteries as in existing technologies.

[0009] In addition, in the above-mentioned car seat heating structure of this utility model, it is preferred that the heat conduction pipe is connected to the equipment box via a valve device, and the valve device is connected to the seat heating control switch installed in the car compartment.

[0010] Based on the above structure, passengers in the carriage can control the valve to open or close via the seat heating control switch. When the valve is open, the equipment box is connected to the heat conduction pipe, thereby enabling the seat cushion to be heated; when the valve is closed, the equipment box is isolated from the heat conduction pipe, thereby stopping the heating of the seat cushion.

[0011] In addition, in the above-mentioned car seat heating structure of the present invention, it is preferable that the heat-conducting pipe has a portion configured as a meandering or spiral shape, which is embedded inside the seat cushion.

[0012] Based on the above structure, since the meandering or spiral shape of the heat pipe occupies a large area inside the seat cushion, it is possible to achieve uniform heating over a large area inside the seat cushion.

[0013] In addition, in the above-mentioned car seat heating structure of this utility model, it is preferable that, while a radiator is provided on the wall of the equipment box, a temperature control switch is provided inside the equipment box to operate the radiator when the temperature inside the equipment box is higher than a specified upper limit value, and to stop the radiator from operating when the temperature inside the equipment box is lower than a specified lower limit value.

[0014] Based on the above structure, it is possible to prevent the temperature inside the equipment box from rising abnormally when the seat heating stops, which could adversely affect the on-board equipment inside the equipment box.

[0015] In addition, in the above-mentioned car seat heating structure of this utility model, it is preferable that the car is an electric vehicle, which has an electric motor as a driving source and a battery pack that supplies power to the electric motor.

[0016] Based on this structure, car seat heating can be achieved without shortening the car's driving range. Attached Figure Description

[0017] Figure 1 is a schematic diagram of a car seat heating structure according to one embodiment of the present invention, showing the front and rear seats as seen from one side of the car interior.

[0018] Figure 2 is a magnified view of the lower part of the rear seat in Figure 1. Detailed Implementation

[0019] The heating structure for a car seat according to the present invention will be described below with reference to the accompanying drawings. In this embodiment, the invention will be described as an example of its application in an electric vehicle.

[0020] Figure 1 is a schematic diagram showing the car seat heating structure of this embodiment, showing the front and rear seats as seen from the left side of the car interior.

[0021] As shown in Figure 1, the car cabin is equipped with front seats 1, rear seats 2, battery pack 3, and multiple in-vehicle devices (4-6).

[0022] The front seats 1 and the rear seats 2 are mounted on the floor panel 7.

[0023] The floor panel 7 is configured to extend horizontally along the length and width of the vehicle, and after extending upward and backward to a certain height in front of the area where the rear seats 2 are installed, it extends horizontally backward (towards the rear of the vehicle compartment).

[0024] A battery pack 3 is disposed below the floor panel 7. The battery pack 3 is approximately flat and rectangular in shape, extending from under the front seat 1 to under the rear seat 2. Therefore, a space is formed between the floor panel 7 under the rear seat 2 and the battery pack 3. An equipment compartment 8 is disposed within this space.

[0025] Inside the equipment box 8, multiple (three in this case) vehicle-mounted devices (4-6) are stored. These vehicle-mounted devices (4-6) are existing vehicle-mounted devices used in the operation of automobiles and are devices that generate a certain amount of heat when operating, such as electronic control devices of automobiles. In this embodiment, as will be described later, these vehicle-mounted devices (4-6) are used as heat sources.

[0026] Here, the equipment compartment 8 is configured, for example, as a cuboid shape that can be stored in the space under the rear seat 2. Furthermore, the walls of the equipment compartment 8 are made of a material with heat-insulating and insulating properties.

[0027] Figure 2 is a magnified schematic diagram of the lower part of the rear seat in Figure 1. As shown in Figure 2, a heat pipe 9 is installed on the equipment box 8. The heat pipe 9 is configured as an inverted "U" shape, with its two ends connected to the rear end and front end of the equipment box 8 respectively through the first valve 10 and the second valve 11; its middle part is arranged (embedded) inside the seat cushion 21 of the rear seat 2 along the length of the vehicle.

[0028] The heat pipe 9 is connected to the equipment box 8 via the first valve 10 and the second valve 11, so that air inside the equipment box 8 can circulate within the heat pipe 9. The heat pipe 9 is made of a material with excellent thermal conductivity (such as metal), thus it can efficiently transfer the heat of the air flowing inside the pipe to the outside.

[0029] The first valve 10 and the second valve 11 open when the seat heating mode is activated and close when the seat heating mode is deactivated. Specifically, although not shown in the figure, the first valve 10 and the second valve 11 are respectively connected to a seat heating control switch, such as one located on the center console inside the vehicle, via a signal line (or wireless communication). The occupant sitting in the driver's or front passenger's seat can activate or deactivate the seat heating mode by operating the seat heating control switch.

[0030] During vehicle startup or operation, the heat generated by the operation of multiple onboard devices (4-6) raises the temperature of the air inside the device housing 8. At this time, if the first valve 10 and the second valve 11 are open, as shown by the thick solid arrow in Figure 2, the heated air inside the device housing 8 flows into the heat pipe 9 and flows in a unidirectional direction (convection) to form an air circulation loop. Since the heat of the air flowing inside the heat pipe 9 is dissipated outside the heat pipe 9, the seat cushion 21 of the rear seat 2 can be heated.

[0031] On the other hand, during vehicle startup or driving, the heat generated by the operation of multiple on-board devices (4-6) will raise the temperature of the air inside the equipment box 8. At this time, if the first valve 10 and the second valve 11 are closed, the air inside the equipment box 8 will not flow into the heat pipe 9, thus preventing the heating of the seat cushion 21 of the rear seat 2.

[0032] To prevent excessively high air temperature inside the equipment compartment 8 from adversely affecting the on-board equipment (4-6) when the seat 2 heating stops, it is preferable to install a radiator (e.g., a fan) connected to the outside of the compartment on the wall of the equipment compartment 8. Simultaneously, a temperature control switch (not shown) is installed inside the equipment compartment 8 to control the operation of this fan (not shown). When the temperature inside the equipment compartment 8 exceeds a predetermined upper limit, the temperature control switch automatically closes, causing the fan to operate; when the temperature inside the equipment compartment 8 falls below a predetermined lower limit, the temperature control switch automatically opens, causing the fan to stop operating. In this way, excess heat inside the equipment compartment 8 can be dissipated to the outside by the fan, ensuring that the temperature inside the equipment compartment 8 remains below the predetermined upper limit.

[0033] Based on the structure described in this embodiment, the heat generated by existing vehicle-mounted devices (4-6) during operation can be effectively used to heat the seats (rear seats 2). Since there is no need to use a dedicated seat heater or perform energy conversion, equipment and operating costs can be reduced, and energy can be saved. In particular, when the car is an electric vehicle, since there is no need to use an on-board battery to power the seat heater as in the prior art, the driving range of the car will not be shortened.

[0034] However, this utility model is not limited to the above-described embodiments and can be implemented in various applications and variations.

[0035] (1) In the above embodiments, the present invention is described as being applied to an electric vehicle, but the present invention is also applicable to automobiles with an engine as the driving source, or hybrid vehicles with an engine and an electric motor as the driving source.

[0036] (2) In the above embodiment, the example of heating the rear seat 2 using the heat generated by the operation of multiple vehicle-mounted devices (4-6) has been described, but the present invention is not limited thereto. Similarly, the heat generated by the operation of multiple vehicle-mounted devices (4-6) can also be used to heat the front seat 1.

[0037] (3) In the above embodiment, the example of the middle part of the inverted "U"-shaped heat pipe 9 being arranged inside the seat cushion 21 of the rear seat 2 along the length of the vehicle has been described, but the present invention is not limited to this. For example, the middle part of the heat pipe 9 may be configured as a meandering or spiral shape, and the meandering or spiral shape of the heat pipe 9 may be embedded inside the seat cushion 21.

[0038] (4) In the above embodiment, the example of setting a first valve 10 at one end of the heat pipe 9 and a second valve 11 at the other end of the heat pipe 9 is described, but the present invention is not limited thereto. For example, either the first valve 10 or the second valve 11 may be omitted.

[0039] (5) There are no special restrictions on the number and configuration of vehicle-mounted equipment (4-6), which can be set arbitrarily according to the actual situation.
