Description

Technical Field

[0001] The present disclosure relates to a system capable of providing heating to a vehicle seat. Background Art

[0002] In order to provide heating to a vehicle seat, a heating wire is usually installed in the seat and operated so that heat is generated by the heating wire.

[0003] However, hot wire has disadvantages as well as advantages.

[0004] First, power needs to be provided when operating the heating wire, resulting in a loss of fuel efficiency and requiring additional devices, such as heating wires for seat heating functions.

[0005] Second, since the seat needs to prevent fire caused by heat and needs to be free from deformation and changes in physical properties caused by heat, it is necessary to adopt a seat material that requires heat resistance.

[0006] Third, since direct contact between the seat having the hot wire embedded therein and the customer is inevitable, there is a risk of burns if the user's bare skin comes into contact with the seat.

[0007] In order to make up for these disadvantages, Korean Utility Model Publication No. 20-1998-0027194 and the like propose a heating system using waste heat of a vehicle.

[0008] However, the related art requires the use of a separate water tank, and thus has disadvantages in that the space of the vehicle is greatly limited, and has a limitation in that it is impossible to adjust the heating intensity.

[0009] The contents described in the description of the related art are to help understanding the background of the present disclosure, and may include contents that are previously unknown to those skilled in the art to which the present disclosure belongs. Summary of the invention

[0010] The present disclosure is intended to solve the above-mentioned problems, and an object of the present disclosure is to provide a seat heating system for a vehicle, which may not require a heating wire in a vehicle seat and implement a heating function using waste heat of exhaust gas to heat the vehicle seat.

[0011] A seat heating system for a vehicle according to one aspect of the present disclosure includes: an exhaust gas inlet pipe, one end of which is connected to a muffler hole formed in a muffler, and the other end is mounted on a vehicle body and connected to a first seat rail coupled to a seat; and an exhaust gas outlet pipe, one end of which is connected to a muffler pipe at a rear end of the muffler, and the other end is connected to the first seat rail.

[0012] Here, the seat rail may have a hollow structure.

[0013] In addition, the seat heating system may further include a second seat rail and a heat exchange pipe for connecting the first seat rail and the second seat rail.

[0014] At this time, a plurality of heat exchange tubes may be constructed, and the opening and closing of the plurality of heat exchange tubes may be individually controlled.

[0015] More specifically, the seat heating system for a vehicle may further include: a rotating plate mounted on the muffler, and one end of the exhaust gas inlet pipe may be coupled through a rotating plate hole formed in the rotating plate to communicate with the muffler hole.

[0016] In addition, the degree of communication between the exhaust gas inlet pipe and the muffler hole can be adjusted by the rotating operation of the rotating plate.

[0017] In addition, the seat heating system for a vehicle may further include: an actuator motor mounted on the muffler, and a power transmission member for transmitting power to the rotating plate through operation of the actuator motor.

[0018] In addition, the power transmission member may include a rod connected to the actuator motor and a gear coupled to an end of the rod, and the rotating plate may be provided with a rotating plate gear meshed with the gear.

[0019] Meanwhile, the exhaust gas inlet pipe and the exhaust gas outlet pipe may be partially provided with corrugated pipes.

[0020] The other end of the exhaust gas inlet pipe may be mounted on the vehicle body in the front-rear direction of the vehicle.

[0021] Next, according to another aspect of the present disclosure, a seat heating system for a vehicle may include: an exhaust gas inlet pipe, one end of which is connected to the muffler hole in the muffler, and the other end is installed on the vehicle body and connected to the first seat rail connected to the seat; an exhaust gas outlet pipe, one end of which is connected to the muffler pipe at the rear end of the muffler, and the other end is connected to the seat rail; and a heating adjustment structure, which is used to adjust the degree of connectivity between the exhaust gas inlet pipe and the muffler hole.

[0022] Here, the heat adjusting structure may include an actuator motor mounted on the muffler, a rotating plate mounted on the muffler, and a power transmission member for transmitting power generated by operation of the actuator motor to the rotating plate.

[0023] In addition, one end of the exhaust gas inlet pipe may be coupled through the rotating plate hole in the rotating plate to communicate with the muffler hole, and the degree of communication between the exhaust gas inlet pipe and the muffler hole may be adjusted by the rotating operation of the rotating plate.

[0024] Furthermore, the power transmission member may include a rod connected to the actuator motor and a gear coupled to an end of the rod, and the rotating plate may be provided with a rotating plate gear meshed with the gear.

[0025] In addition, the seat heating system may further include a second seat rail and a heat exchange pipe for connecting the first seat rail and the second seat rail, and a plurality of heat exchange pipes may be configured.

[0026] The other end of the exhaust gas inlet pipe may be mounted on the vehicle body in the front-rear direction of the vehicle.

[0027] As in the conventional art, when operating the heated wire seat, it may be inevitable to supply power, resulting in a loss of fuel efficiency, but the present disclosure uses exhaust gas waste heat to achieve the heating function, thereby improving fuel efficiency compared to the conventional art.

[0028] Additionally, it is not necessary to use heat wires and related components to heat the interior of the seat, thereby saving costs by eliminating components.

[0029] In addition, since conventional seats having heat wires embedded therein need to prevent fires in the seat portion due to heat and need to be free from deformation and changes in physical properties due to heat, seats made of materials having excellent heat resistance are required, but the present disclosure, which uses waste heat to increase the temperature of the seat rails and performs a heating function through heat dissipation of the seat rails, can employ seat materials that are not related to heat resistance, thereby saving costs.

[0030] Additionally, since the seat rails in the vehicle package do not come into direct contact with the customer, there is no risk of burns.

[0031] Therefore, the present disclosure can be applied to all vehicles regardless of the type or concept of the vehicle, and can greatly save manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] For a complete understanding of the present disclosure, its operating advantages and objectives attained by carrying out the present disclosure, reference should be made to the accompanying drawings which illustrate preferred exemplary embodiments of the present disclosure and the matters described therein.

[0040] In describing the preferred exemplary embodiments of the present disclosure, descriptions or repeated descriptions of known technologies that may unnecessarily obscure the gist of the present disclosure will be reduced or omitted.

[0041] Figure 1 is a diagram schematically showing a seat heating system for a vehicle according to the present disclosure.

[0042] Figure 2A It shows Figure 1 An enlarged view of portion A is shown, Figure 2B It shows that from Figure 2A Illustration of the cross-sectional shape observed at X shown, Figure 3 It shows Figure 1 An enlarged view of portion B is shown, Figure 4A yes Figure 1 An enlarged view of portion C is shown, and Figure 4B is an exploded view showing part C.

[0043] In the following, reference will be made to Figures 1 to 4B A seat heating system for a vehicle according to an exemplary embodiment of the present disclosure is described.

[0044] A seat heating system for a vehicle according to the present disclosure is a system capable of providing heating to a seat using waste heat of exhaust gas instead of a conventional heating wire installed in the seat.

[0045] To this end, the seat heating system includes an actuator motor 110, power transmission components 121, 122, a rotating plate 130, an exhaust gas inlet pipe 140, an exhaust gas outlet pipe 150, a heat exchange pipe 160, and the like.

[0046] The seat for the vehicle is coupled to a seat rail 30 which is mounted on the vehicle body in the front-rear direction of the vehicle and is configured to be movable along the seat rail 30 in the front-rear direction of the vehicle.

[0047] In addition, a pair of seat rails 30 are respectively installed at each position corresponding to both side portions of the lower surface of the vehicle seat.

[0048] The cross section of a general seat rail has a solid form with a complete interior, but Figure 2B As shown, the seat rail according to the present disclosure has a hollow structure having a hollow interior such as a pipe.

[0049] In addition, heat exchange pipe 160 for connecting the pair of seat rails 30 is configured to allow a heat source to circulate through seat rails 30 and heat exchange pipe 160 to provide heating for the vehicle seat, making it possible to increase the heat dissipation area, thereby improving heating efficiency.

[0050] The heat source supplied to the seat rails 30 and the heat exchange pipe 160 uses the exhaust gas of the vehicle, and for this purpose, the seat heating system includes: an exhaust gas inlet pipe 140, one end of which is connected to the muffler hole 12 formed in the muffler 10, and the other end is connected to any one of a pair of seat rails 30; and an exhaust gas outlet pipe 150, one end of which is connected to the outer surface of the muffler pipe 20 installed on the rear end of the muffler 10, and the other end is connected to any one of the pair of seat rails 30, so that the exhaust gas is introduced into the seat rails 30 through the exhaust gas inlet pipe 140 to circulate through the heat exchange pipe 160 and the seat rails 30, and then discharged to the muffler pipe 20 through the exhaust gas outlet pipe 150.

[0051] As described later, exhaust gas inlet pipe 140 and exhaust gas outlet pipe 150 are more preferably connected to the same seat rail of the pair of seat rails 30 in consideration of smooth circulation and efficiency of exhaust gas.

[0052] In addition, a plurality of heat exchange tubes 160 may be provided, and more preferably, three or more heat exchange tubes including a first heat exchange tube 161 , a second heat exchange tube 162 , and a third heat exchange tube 163 are provided.

[0053] One end of the exhaust gas inlet pipe 140 communicates with the muffler hole 12 formed in the muffler 10 , and the present disclosure can adjust the degree of communication between the exhaust gas inlet pipe 140 and the muffler hole 12 through a heating adjustment device, thereby adjusting the heating level.

[0054] The heating adjustment device includes an actuator motor 110 , a power transmission component, and a rotating plate 130 .

[0055] The rear surface of the muffler 10 is formed with a rotating plate seating groove 11 , and the rotating plate 130 is seated in the rotating plate seating groove 11 .

[0056] In addition, one end of the exhaust gas inlet pipe 140 is configured to be coupled to pass through the rotating plate hole 133 formed in the rotating plate 130 so as to communicate with the muffler hole 12 .

[0057] Therefore, the seat heating system includes an actuator motor 110, a rod 121 as a power transmission component, and a gear 122 for adjusting the degree of connectivity between the exhaust gas inlet pipe 140 and the muffler hole 12 and performing a rotation operation of the rotating plate 130 by rotationally operating the rotating plate 130, a gear connecting hole 131 is formed on the central portion of the rotating plate 130, and a rotating plate gear 132 meshing with the gear 122 is formed on the inner diameter of the gear connecting hole 131.

[0058] The actuator motor 110 transmits power to the gear 122 through the rod 121 so that the gear 122 rotationally operates.

[0059] When the gear 122 rotationally operates, the rotating plate gear 132 coupled to the gear rotationally operates together.

[0060] As a result, the rotating plate 130 rotationally operates on the rotating plate seating groove 11 and adjusts the position of the exhaust gas inlet pipe 140 installed on the rotating plate hole 133 , thereby adjusting the degree of communication between the exhaust gas inlet pipe 140 and the muffler hole 12 .

[0061] Furthermore, in order to absorb displacement due to the rotation of the rotating plate 130 of the exhaust gas inlet pipe 140 , preferably, the exhaust gas inlet pipe 140 is partially formed with a corrugated pipe 141 , and the corrugated pipe 141 is formed adjacent to the rotating plate 130 .

[0062] That is, as shown in the figure, the exhaust gas inlet pipe 140 is bent after extending from one end connected to the rotating plate 130, and can be bent several times, and a pleated pipe 141 adjacent to the rotating plate 130 is formed before the bent portion, thereby facilitating the change of the position of the exhaust gas inlet pipe 140.

[0063] In addition, if Figure 3 As shown, the exhaust outlet pipe 150 may be formed with a corrugated pipe 151 adjacent to the muffler pipe 20 to absorb the movement of the muffler pipe 20 so that the exhaust outlet pipe 150 does not move significantly.

[0064] Alternatively, the corrugated tubes 141, 151 may be configured to be replaced by a rubber member.

[0065] Next, we will refer to Figure 5 and FIG. 6A to FIG. 6DAn operating sequence of a seat heating system according to the present disclosure is described.

[0066] When a heating switch provided in the vehicle is turned on (S11), an operation signal is transmitted to the actuator motor 110, and as Fig. 6A As shown, the rotating plate 130 is rotated by the operation of the actuator motor 110 in response to the received operation signal (S12).

[0067] Before operating the heating system, Figure 6B As shown, the rotating plate hole 133 and the muffler hole 12 are not communicated with each other at all, so that the exhaust gas is not introduced through the exhaust gas inlet pipe 140 .

[0068] When the rotating plate 130 rotates counterclockwise (CCW) by operation S12, the rotating plate hole 133 and the muffler hole 12 communicate with each other, and when the rotation amount of the rotating plate is gradually adjusted to gradually adjust the heating level, Figure 6C The steps shown and Figure 6B Adjustments in the steps shown are possible.

[0069] As another exemplary embodiment, it is possible to adjust the circulation area of ​​the exhaust gas instead of the circulation amount adjustment, thereby adjusting the heating intensity.

[0070] That is, it is possible to individually control the opening and closing of the plurality of heat exchange tubes, thereby adjusting the heating level.

[0071] Specifically, the first heating stage may allow the exhaust gas to circulate only through the first heat exchange tube 161, the second heating stage may allow the exhaust gas to circulate by opening the first heat exchange tube 161 and the second heat exchange tube 162, and the third heating stage may allow the exhaust gas to circulate through all of the first heat exchange tube 161, the second heat exchange tube 162 and the third heat exchange tube 163.

[0072] In one example, it has been described that the direction in which the rotating plate 130 rotates counterclockwise is the direction in which the heating system is operated, and the opposite direction thereto may also be set.

[0073] As mentioned above, in Figure 6C or Fig.6D In the case of the status shown, 7A to 7C As shown in the flow, the exhaust gas is circulated through the exhaust seat rail 30 and the heat exchange pipe 160 through the exhaust inlet pipe 140 (S13), the exhaust gas is discharged through the exhaust outlet pipe 150 after the circulation, and the temperature of the seat part of the vehicle is increased by this operation (S14).

[0074] Thereafter, when the heating switch is turned off ( S15 ), the operation signal is transmitted to the actuator motor 110 , and the rotating plate 130 is rotated clockwise by the operation of the actuator motor 110 in response to the received operation signal ( S16 ).

[0075] Then, return to Figure 6B In the state shown, the exhaust gas is brought into a state of not being circulated to the seat rail 130 (S17), thereby lowering the temperature of the seat portion of the vehicle (S18).

[0076] As described above, the seat heating system for a vehicle according to the present disclosure may not require a conventional heat wire seat, and provide heating to the seat through exhaust gas instead of heat wires.

[0077] As described above, the present disclosure has been described with reference to the exemplary drawings, but the present disclosure is not limited to the described exemplary embodiments, and it is obvious to those skilled in the art that various modifications and changes can be made to the present disclosure without departing from the spirit and scope of the present disclosure. Therefore, modified examples or changed examples should be included in the claims of the present disclosure, and the scope of the present disclosure should be interpreted based on the appended claims.
