Description

Technical Field

[0001] The invention relates to the field of active seat temperature control equipment, and in particular to a seat temperature control system. Background Art

[0002] Seat temperature control is common in seats inside vehicles, and generally has active seat ventilation and seat heating functions. The principle of seat ventilation is to set a fan inside the seat to create the effect of blowing air outwards or sucking air inwards. Seat heating is achieved by laying heating wires inside the seat.

[0003] However, seat ventilation is based on the air flow effect of the fan, which has a poor cooling effect on users in the hot summer and cannot meet the effect of quickly cooling the seat. The seat heating and seat ventilation are two separate systems, and the heating wire needs to be installed away from the fan position, which increases the difficulty of installation and the complexity of the interior of the car seat, making it difficult to control the cost. Summary of the invention

[0004] The present invention provides a seat temperature control system, aiming to solve the problems of low integration and separation of heating and cooling systems in existing seat temperature control devices.

[0011] Preferably, the first liquid pipe and the second liquid pipe are connected to the reflux pipe after passing through the fixing member; the other end of the reflux pipe is connected to the temperature control module.

[0012] Preferably, the temperature control module includes a semiconductor refrigeration element, a heat exchange head and a water drain; one side of the semiconductor refrigeration element is connected to the heat exchange head, and the heat exchange head is connected to the return pipe; the other side of the semiconductor refrigeration element is in contact with the water drain.

[0013] Preferably, it also includes a control module, which includes a temperature sensor, a pressure sensor and a main control chip.

[0015] Compared with the prior art, the seat temperature control system provided by the present invention has the following beneficial effects: By setting a fixing member to fix and store the parallel first liquid pipe and the second liquid pipe, for the installation angle, the user can directly lay the fixing members in the seat according to the number of fixing members, that is, only one fixing member of a set length is needed, and the temperature control module is used to output cold liquid or hot liquid according to the needs, so as to realize the cooling and heating functions of the seat, integrate the active temperature control function of the seat, and have a simple structure and are easy to install. It is especially suitable for the modification of old seats that do not have cooling and heating functions. At the same time, the system swaps the positions of the first liquid pipe and the second liquid pipe through the torsion part, so that the system can still realize the independent control of different parts of the seat through the original fixing member, and the partitions do not affect each other, further improving the integration of the seat temperature control system, greatly reducing the modification cost, and reducing the space occupied inside the seat. Furthermore, the system can realize the close arrangement of the inside of the seat through a single pipeline structure, without considering the avoidance of other structures such as fans and heating wires, and has higher cooling and heating efficiency and space utilization.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0031] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0032] Please combine Figure 1 ,and Figure 2 and Figure 3 The first embodiment of the present invention discloses a seat temperature control system, which is installed in a seat 100 to adjust the temperature of a seating surface of the seat 100. The seat may be a car seat, a sofa, or other types of seating equipment that can house objects.

[0033] The seat temperature control system of the first embodiment of the present invention comprises a pipeline 1, a water pump 2, a valve body 3, a temperature control module 4 and a control module 5. The pipeline 1 is connected to the temperature control module 4, the water pump 2 and the valve body 3. The control module 5 is used to control the start and stop and cooperation of the water pump 2, the valve body 3 and the temperature control module 4. For example, the opening and closing of any pipeline of the valve body 3, the start and stop of the water pump, the start and stop of the cooling or heating function of the temperature control module 4, etc. can be controlled.

[0034] Please combine Figure 3 and Figure 4The pipeline 1 includes a fixing part 11, a first liquid pipe 12 and a second liquid pipe 13. The first liquid pipe 12 and the second liquid pipe 13 are positioned in the fixing part 11. The first liquid pipe 12 and the second liquid pipe 13 are arranged in parallel. The fixing part 11 conducts temperature to the seat 100 based on the temperature of the first liquid pipe 12 or the second liquid pipe 13.

[0035] It is understandable that Figure 2 As shown in , in this embodiment, the pipeline 1 is used to be laid inside the seat 100 and close to the contact surface, and the remaining structures can be arranged in the external area of ​​the seat 100 such as the bottom of the seat 100. Figure 2 The transverse S-shaped paving method shown in the figure is only an example of paving. In other embodiments, it can also be set to a longitudinal S-shaped paving method, or it can also be set to a cross paving method, that is, the paving method is not limited.

[0036] It can be understood that the fixing member 11 is a thermal conductive material, such as a polyurethane material, a heat dissipating silicone material, etc., and the fixing member 11 contacts the bottom of the contact surface of the seat 100 to achieve temperature conduction. Or in some other embodiments, a temperature balancing layer 200 is provided between the contact surface of the fixing member 11 and the seat 100, and the temperature balancing layer 200 can increase the contact area with the fixing member 11 and improve the temperature conduction effect.

[0037] The cross-sectional profile of the fixing member 11 can be set to be a rectangle (such as Figure 4 ), or a rectangular structure with semicircular ends (as shown in Figure 5 When the cross-sectional profile of the fixing member 11 can be set as a rectangle, since the top of the fixing member 11 is a flat structure, it has a larger contact and heat transfer area than the top of the arc structure, so it can be directly set to be attached to the bottom of the contact surface of the seat 100 (as shown in FIG. Figure 6 If a curved top structure is provided, the contact surface is reduced, as shown in Figure 7 As shown in , a temperature balancing layer 200 can be provided in combination. Since the temperature balancing layer 200 is an integrated structure, it has a better sitting feeling compared to the rectangular distributed fixing member 11, and the seat 100 has a lower foreign body sensation, thereby improving the comfort of the user. Of course, the cross-sectional structure of the fixing member 11 can also be set to other shapes, as long as two parallel passages can be opened to parallelly fix the first liquid pipe 12 and the second liquid pipe 13 therein, and this is not limited here.

[0038] One end of the first liquid pipe 12 and the second liquid pipe 13 are respectively connected to different outlets of the valve body 3 to control the flow of liquid in the first liquid pipe 12 or the second liquid pipe 13 through the valve body 3. In this embodiment, the valve body 3 is a three-way valve, two outlets of which are respectively connected to the first liquid pipe 12 and the second liquid pipe 13, and the other inlet is connected to the water pump 2.

[0039] Please continue to combine Figure 8 and Fig. 9 The fixing member 11 is provided with a twisting portion 111 , and the twisting portion 111 exchanges the heat conducting surfaces of the fixing member 11 and the seat 100 .

[0040] After the liquid flowing in the first liquid pipe 12 or the second liquid pipe 13 forms a temperature difference with the fixing part 11, the temperature is transferred to the fixing part 11. For example, in this embodiment, the first liquid pipe 12 is close to the side of the seat 100 that needs to be cooled (refrigerated). The first liquid pipe 12 is close to the contact surface of the seat 100, and the second liquid pipe 13 is far away from the contact surface of the seat 100. The first liquid pipe 12 flows into the cold liquid after being cooled by the temperature control module 4, and the surface of the fixing part 11 close to the contact surface of the seat 100 is quickly cooled. Finally, the low temperature is transferred to the surface of the seat 100 to achieve a cooling effect. The heating function is the same as the cooling function. It only needs to control the temperature control module 4 to heat the liquid, which will not be repeated here.

[0041] It can be understood that the fixing member 11 fixes the first liquid pipe 12 and the second liquid pipe 13 synchronously and in parallel, realizing the sequential arrangement structure of the surface of the seat 100, the first liquid pipe 12, and the second liquid pipe 13. That is, relative to the surface of the seat 100, the first liquid pipe 12 directly controls the temperature of the seat 100 in this area, and the second liquid pipe 13 far away from the surface of the seat 100 has less effect on the surface temperature control of the seat 100 due to the layer of the first liquid pipe 12.

[0042] It is understandable that Fig. 9 As shown in , in this embodiment, the twisting part 111 is a twisting structure of a certain part of the pipeline 1. In combination with the seat 100 with the backrest area 102, the twisting part can be set at the connection between the backrest area 102 and the cushion area 101. Twisting is to rotate the fixing member 11 in one direction by a certain angle, and to exchange the positions of the first liquid pipe 12 and the second liquid pipe 13 inside the seat 100, so as to form a zoned temperature control effect of different liquid pipe temperature conduction in two different areas of the backrest area 102 and the cushion area 101. For example, in this embodiment, the structure inside the cushion area 101 is a structure in which the surface of the seat 100, the first liquid pipe 12, and the second liquid pipe 13 are arranged in sequence. After the twisting part 111 is twisted and exchanged at an angle of 180°, the interior of the backrest area 102 forms a structure in which the surface of the seat 100, the second liquid pipe 13, and the first liquid pipe 12 are arranged in sequence.

[0043] Optionally, as an embodiment, the torsion portion 111 may also be configured as an intermediate transition structure connected to the pipeline 1 , and the first liquid pipe 12 and the second liquid pipe 13 may switch the connection positions at the torsion portion 111 , thereby forming a replacement effect.

[0044] During installation, only one pipeline 1 is needed, which is first laid in the cushion area 101 to form a structure in which the surface of the seat 100, the first liquid pipe 12, and the second liquid pipe 13 are arranged in sequence in the cushion area 101. Then, the fixing part 11 is twisted 180° at the connection position between the cushion area 101 and the backrest area 102, and the pipeline 1 is continued to be laid into the backrest area 102 to form a structure in which the surface of the seat 100, the second liquid pipe 13, and the first liquid pipe 12 are arranged in sequence.

[0045] When in use, when it is necessary to cool and cool the contact surface of the seat 100, that is, the cushion area 101 and the backrest area 102 simultaneously, the temperature control module 4 is turned on to cool the liquid, the water pump 2 is started, and the two outlets of the valve body 3 are opened synchronously, and the cold liquid enters the first liquid pipe 12 and the second liquid pipe 13 respectively, then the first liquid pipe 12 directly cools the cushion area 101, and the second liquid pipe 13 directly cools the backrest area 102. Since the second liquid pipe 13 in the cushion area 101 is far away from the surface of the seat 100, the temperature loss of the liquid flowing through the cushion area 101 is small, and the cooling of the backrest area 102 is not affected. Similarly, when the first liquid pipe 12 enters the backrest area 102 after temperature conduction, since it is far away from the surface of the backrest area 102, the higher temperature of the first liquid pipe 12 will not affect the cooling of the backrest area 102.

[0046] When a single area needs to be cooled, for example, the backrest area 102 is cooled, the control valve body 3 opens the second liquid pipe 13. When the liquid flows through the cushion area 101, the second liquid pipe 13 is far away from the surface of the cushion area 101, so the temperature of the cushion area 101 is less affected, and the temperature loss of the second liquid pipe 13 itself is also low, so the backrest area 102 can be cooled normally. The cooling of the cushion area 101 is similar, and will not be repeated here.

[0047] It can be understood that since the fixing member 11 fixes the first liquid pipe 12 and the second liquid pipe 13 inside at the same time, there is a slight temperature influence between the two liquid pipes. For example, when the user starts the cooling of the cushion area 101, the liquid in the first liquid pipe 12 flowing into the backrest area 102 rises from the original set 17 degrees Celsius to about 27 degrees Celsius after 10 minutes, which is still at a relatively low temperature for the use temperature. The first liquid pipe 12 located at the bottom of the backrest area 102 has little effect on the surface temperature of the backrest area 102, but part of the temperature of the first liquid pipe 12 will be transmitted to the second liquid pipe 13, which has the effect of pre-cooling. Then, when the second liquid pipe 13 is cooled and cooled, the pre-cooled part will reduce the temperature loss of the second liquid pipe 13.

[0048] It can be understood that liquid flows out of the pipeline 1 after passing through the seat cushion area 101 and the backrest area 102, that is, the first liquid pipe 12 and the second liquid pipe 13 are connected with the return pipe 14 after passing through the fixing part 11, and the return pipe 14 mixes the liquid flowing out of the first liquid pipe 12 and the second liquid pipe 13, and flows into the temperature control module 4 to reheat or cool the liquid.

[0049] See also Fig.10 The temperature control module 4 includes a semiconductor refrigeration component 41, a heat exchange head 42 and a temperature exhaust component. One side of the semiconductor refrigeration component 41 is connected to the heat exchange head 42. The heat exchange head 42 is connected to the return pipe 14. The return pipe 14 transfers the mixed liquid to the heat exchange head 42, and then transfers it to the outside after being heated or cooled by the semiconductor refrigeration component 41.

[0050] The other side of the semiconductor refrigeration element 41 is in contact with the heat dissipation component. One side of the semiconductor refrigeration element 41 is connected to the heat exchange head 42, and the other side is connected to the heat dissipation component. The user can control the cooling and heating directions of both sides by controlling the current direction of the semiconductor refrigeration element 41. When one side is cooling, the other side is heating. That is, by controlling the cooling and heating control of one side of the heat exchange head 42, the output of cold and hot liquids can be achieved. The heat dissipation component is used to assist the other side of the semiconductor refrigeration element 41 in heat dissipation or auxiliary heating, so as to improve the working efficiency of the semiconductor refrigeration element 41 during cooling or heating.

[0051] It is understandable that Fig.10 As shown in the figure, the temperature exhaust component includes a water head 43, a fluid pump 44, a water drain 45 and a connecting pipe. The water head 43 contacts the side of the semiconductor refrigeration component 41. The temperature exhaust component provides power to the fluid through the fluid pump 44, and the water drain 45 improves the temperature exchange between the fluid in the pipeline and the room temperature.

[0052] It can be understood that in this embodiment, the heat exchange head 42 and the water head 43 are both water-cooled head structures in contact with the surface of the semiconductor refrigeration component 41, which are used to make the fluid flow through the surface of the semiconductor refrigeration component 41 and then flow out. Since the water-cooled head is a common water cooling equipment structure, the specific principle will not be repeated here.

[0053] See also Fig.11 The control module 5 includes a temperature sensor 51, a pressure sensor 52 and a main control chip 53. The temperature sensor 51 detects the surface temperature of the fixing member 11. The main control chip 53 controls the output flow of the valve body 3 and the working temperature of the temperature control module 4 based on the value of the temperature sensor 51. The pressure sensor 52 is arranged in the seat cushion area 101 and / or the backrest area 102.

[0054] The main control chip 53 controls the valve body 3, the temperature control module 4 and the start and stop of the water pump 2 based on the value of the pressure sensor 52. When a user sits on the seat 100, the change in the value of the pressure sensor 52 can be used to determine whether there is someone on the seat 100, and the main control chip 53 can automatically control the system to start.

[0055] It is understood that the main control chip 53 can be set as a micro control unit for writing control programs to execute control instructions, and the user can realize automatic control and dynamic control of the system through the main control chip 53. For example, the user sets a timer to start cooling and heating.

[0056] The system also includes a vehicle networking module (not shown), which is connected to the vehicle computer, and the vehicle networking module is connected to the control module 5. The vehicle networking module is used to work together with the vehicle computer to achieve joint control of the vehicle-mounted equipment and the system. For example, when the user sets the in-vehicle air conditioner to 24 degrees Celsius, the system can obtain the set temperature of the in-vehicle air conditioner through the vehicle networking module, and actively control the temperature control module 4 to also output 24 degrees Celsius liquid to lower the seat surface to the set temperature, or after the user remotely starts the vehicle through remote control, the system synchronously starts the preset seat cooling or heating function based on the vehicle networking module.

[0057] Compared with the prior art, the seat temperature control system provided by the present invention has the following beneficial effects: By setting a fixing member to fix and store the parallel first liquid pipe and the second liquid pipe, for the installation angle, the user can directly lay the fixing members in the seat according to the number of fixing members, that is, only one fixing member of a set length is needed, and the temperature control module is used to output cold liquid or hot liquid according to the needs, so as to realize the cooling and heating functions of the seat, integrate the active temperature control function of the seat, and have a simple structure and are easy to install. It is especially suitable for the modification of old seats that do not have cooling and heating functions. At the same time, the system swaps the positions of the first liquid pipe and the second liquid pipe through the torsion part, so that the system can still realize the independent control of different parts of the seat through the original fixing member, and the partitions do not affect each other, further improving the integration of the seat temperature control system, greatly reducing the modification cost, and reducing the space occupied inside the seat. Furthermore, the system can realize the close arrangement of the inside of the seat through a single pipeline structure, without considering the avoidance of other structures such as fans and heating wires, and has higher cooling and heating efficiency and space utilization. Then, because the system uses contact cooling, it is not necessary to punch holes for ventilation in the seat, which improves the sealing of the seat and facilitates the cleaning and service life of the seat surface.

[0058] From the perspective of use, the seat surface formed by this system and the stacked structure of two liquid pipes arranged in sequence ensure that the temperature adjustment between the various seat partitions does not affect each other, thereby greatly reducing the temperature loss during liquid flow and improving energy utilization.

[0059] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
