Description

Technical Field

[0001] The invention relates to the technical field of temperature distribution detection, and in particular to a method for detecting temperature distribution of automobile seat heating. Background Art

[0002] At present, there are certain limitations in the detection technology of car seat heating temperature distribution. Traditional detection methods mostly use fixed temperature measuring devices or single contact points for temperature testing. This method has significant limitations and cannot accurately reflect the actual temperature distribution of car seats during actual use. Fixed temperature measuring devices can usually only collect temperature at a limited number of fixed positions on the seat surface, lack comprehensiveness and flexibility, and easily miss areas with uneven temperature distribution. In addition, since this fixed temperature measurement method is a static test, it cannot simulate the pressure distribution generated when the human body contacts the seat under dynamic conditions, resulting in a large deviation between the test data and the actual use conditions. The traditional single contact point temperature measurement method also has shortcomings. This method relies on point-to-point temperature acquisition, has a narrow detection range, and cannot fully cover the entire heating area of ​​the seat. In actual use scenarios, different pressure distributions will be generated when the human body contacts the seat, especially when the sitting posture changes or under different weight conditions, the heating temperature transfer of the seat will also change. Therefore, the test of a single contact point cannot restore the actual thermal perception of the human body to the seat heating system, which can easily lead to inaccurate test results.

[0026] The working principle of a method for detecting the heating temperature distribution of a car seat is as follows: after laying the car seat back flat, place the car seat on a conveyor belt; convey the car seat to the bottom of the installation frame 101 through the conveyor belt; in the process of moving the car seat by the conveyor belt, energize the heating wire inside the car seat to increase the temperature of the surface of the car seat; control the telescopic rod of the hoisting telescopic electric cylinder 104 to move the temperature measuring component to a position in contact with the surface of the car seat (when in contact, the silicone sleeve 139 will be squeezed and deformed, and this process will cause the pressure inside the silicone sleeve 139 to increase, and the pressure will be transmitted to the driving pressure chamber 114 through the pressure guiding column 127, and then the simulated downward pressure piston 126 will be pushed to slide, and a Hall sensor is provided on the driving pressure chamber 114 When the simulated pressing piston 126 moves, the distance between the magnetic field of the simulated pressing piston 126 and the Hall sensor will change. The voltage signal of the Hall sensor is used to determine whether the silicone sleeve 139 is in contact with the surface of the car seat, and it is used as an instruction for the telescopic rod of the hoisting telescopic electric cylinder 104 to stop moving); at the same time, controlling the extension and contraction of the telescopic rod of the swing electric cylinder 107 can also drive the swing of the swing rod 109. The swing of the swing rod 109 will drive the swing frame 108 to swing. The swing of the swing frame 108 will drive the entire temperature measuring component to swing. At this time, the temperature of the car seat back can be measured (generally, the car seat back cannot be completely flat); the temperature measuring component simulates the pressure of the human body on the surface of the car seat, making it more suitable for actual usage scenarios. This process requires starting the simulated driving motor 110, the output shaft of the simulated driving motor 110 will drive the sliding shaft 115 to rotate, the sliding shaft 115 drives the sealing shaft 124 to rotate, the sealing shaft 124 drives the simulated downward pressure blade 125 to rotate, and the simulated downward pressure blade 125 drives the liquid inside the simulated pressure chamber 113 to flow in the direction of the simulated downward pressure piston 126. At this time, the flowing liquid will impact the simulated downward pressure piston 126, thereby applying a force to the simulated downward pressure piston 126, so that the simulated downward pressure piston 126 slides inside the driving pressure chamber 114 (it should be noted that the simulated pressure chamber 113 is provided with a channel port for balancing the internal and external pressure difference, and a hose is connected to the channel port The other end of the hose is connected to the housing of the simulated driving motor 110 through a rolling belt to prevent the liquid inside the simulated pressure chamber 113 from leaking out through the channel port) the simulated pressing piston 126 slides downward inside the driving pressure chamber 114, squeezing the air inside the driving pressure chamber 114, thereby increasing the pressure inside the driving pressure chamber 114, and increasing the pressure inside the silicone sleeve 139 through the pressure guiding pipe column 127, thereby increasing the pressure of the silicone sleeve 139 on the surface of the car seat. Due to the increase in pressure, the silicone sleeve 139 will also deform. At this time, the contact area between the silicone sleeve 139 and the surface of the car seat will also increase, and the situation of a heavier person sitting on a car seat can be simulated.

[0027] By moving the position of the temperature measuring component, the temperature of different positions on the surface of the car seat can be detected; the temperature of the heated car seat will be transferred to the silicone sleeve 139, and then the temperature will heat the liquid and the resistance wire inside the heat cycle temperature detection channel 143. The resistance value of the resistance wire will change after heating. The heating temperature of the silicone sleeve 139 can be judged by the resistance of the resistance wire, that is, the temperature of the car seat heated and transferred to the silicone sleeve 139 (simulating the situation where the temperature is transferred to the human body). Generally, this temperature will be higher than the human body temperature. In addition, the circulation simulation motor 128 is started, and the output shaft of the circulation simulation motor 128 drives the circulation simulation active gear 129 to rotate, and the circulation simulation active gear 129 drives the circulation simulation passive gear 130 to rotate, and the circulation simulation passive gear 130 drives the heat-conducting sleeve 131 to rotate, and the heat-conducting sleeve 131 drives the circulation centrifugal paddle 135 to rotate, and the circulation centrifugal paddle 135 drives the liquid inside the centrifugal circulation heat dissipation chamber 137 to rotate. After the liquid rotates, it will be affected by the centrifugal force and flow toward the edge direction of the inner wall of the centrifugal circulation heat dissipation chamber 137, and then guided by the edge guide groove 140, the liquid flows into the discharge pipe 142, and then flows into the heat circulation temperature detection channel 143 through the first channel opening 144, and is guided by the heat circulation temperature detection channel 143, The liquid flows to the second channel opening 145, and then is transported to the middle of the centrifugal circulation heat dissipation chamber 137 through the reflux pipe 141. Due to the rotation of the circulation centrifugal paddle 135, the centrifugal The pressure in the middle of the centrifugal circulation heat dissipation chamber 137 decreases. At this time, the liquid replenished through the return pipe 141 will be driven to rotate again, and a circulating liquid can be formed in the heated circulation temperature detection channel 143 to simulate the flow of human blood. This process requires cooling the liquid flowing out of the heated circulation temperature detection channel 143, so as to facilitate the collection of temperature data at different positions of the car seat and ensure that the temperature of the liquid in the heated circulation temperature detection channel 143 is close to the human body temperature when each temperature measuring point is measured. Therefore, it is necessary to cool the liquid in the heated circulation temperature detection channel 143 (it may also heat up, so a heating wire is set in the centrifugal circulation heat dissipation chamber 137 to heat the liquid to body temperature. The temperature sensors set in the first channel port 144 and the second channel port 145 can detect the temperature of the liquid flowing into and out of the heated circulation temperature detection channel 143 in real time, so as to control the start of the heating wire in the sealed heat-conducting cover 134).Since the liquid inside the centrifugal circulation heat dissipation chamber 137 will continuously contact with the circulating centrifugal paddle 135, the temperature will be transferred to the circulating centrifugal paddle 135, and the circulating centrifugal paddle 135 will transfer the temperature to the heat-conducting sleeve 131, and then to the heat sink 132. Since the heat sink 132 rotates with the heat-conducting sleeve 131, the heat sink 132 will continuously contact with the air at this time. The rotation of the heat sink 132 will also drive the air flow, so it will continuously contact with the core air, thereby transferring the temperature to the air, and then realizing the cooling of the liquid inside the centrifugal circulation heat dissipation chamber 137. Compare all the collected temperature data, judge the difference between multiple temperature data, and obtain the overall temperature distribution uniformity of the car seat heating area.

[0028] The pressure between the silicone sleeve 139 and the car surface can be controlled by simulating the rotation speed of the drive motor 110. The rotation speed of the drive motor 110 directly affects the rotation speed of the simulated downward pressure blade 125. The rotation speed of the simulated downward pressure blade 125 affects the impact force of the liquid inside the simulated pressure chamber 113 driven by the simulated downward pressure blade 125 on the simulated downward pressure piston 126, thereby adjusting the pressure on the simulated downward pressure piston 126. At this time, the pressure inside the silicone sleeve 139 can be controlled to simulate the situation where people of different body shapes and weights sit on the car seat. When the output shaft of the simulated drive motor 110 rotates, it will drive the rotating swing plate 123 on the sealing shaft 124 and the sliding block 117 on the sliding shaft 115 to rotate, so the cylindrical sealing tube 120 and the pressing connecting rod 118 will rotate, and the cylindrical sealing tube 120 and the pressing connecting rod 118 will swing outward due to the centrifugal force. At this time, the sliding block 117 is pulled on the sliding shaft 115 by the pulling of the pressing connecting rod 118, so that the spring 119 is pressurized, causing the spring 119 to undergo elastic deformation. At this time, the density of the spring 119 will change. Therefore, the deformation amount of the spring 119 can be determined by detecting the inductance of the spring 119 itself (the denser the The larger the inductance, the larger the inductance); the rotation of the cylindrical sealing tube 120 will also drive the liquid inside the cylindrical sealing tube 120 to rotate, and the liquid inside the cylindrical sealing tube 120 will flow outward due to the centrifugal force. Since the density of the float 121 is less than the density of the liquid inside the cylindrical sealing tube 120, the float 121 will move toward the direction of the spring 119. When the float 121 contacts the conductive contact piece 106, all the conductive contact pieces 106 in each cylindrical sealing tube 120 are turned on. At this time, it means that the speed of the simulated drive motor 110 is too high and needs to be stopped. It is used as a signal command for the simulated drive motor 110 to stop. At this time, the pressure inside the silicone sleeve 139 reaches the maximum value.
