[0003] The quality of the massage effect produced by a massage airbag is related to the inflation speed of the airbag assembly (the speed at which the airbag assembly expands to its maximum extent after being inflated). This speed is influenced by many factors, including the quality of the small airbags themselves, the sealing of the interconnecting structures between the small airbags, and whether the welding of the air pipes on the airbag assembly affects the air flow rate. Therefore, testing the inflation speed of massage airbags is a very important step in ensuring their quality. However, there is currently a lack of devices capable of detecting the inflation speed of massage airbags. To this end, this application proposes an inflation detection device for automotive seat massage airbags. Utility Model Content

Based on the embodiments of the present invention, all other embodiments that can be realized by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example

[0030] like Figure 1 As shown, the utility model provides an automobile seat massage air bag inflation detection device, comprising: a plurality of storage assemblies 100, which are suitable for storing air bag groups; an air flow distribution assembly 200, which is suitable for connecting the air bag groups in each storage assembly 100 and constantly supplying air to the air bag groups to make them expand, so that the corresponding storage assembly 100 is unfolded; a speed indicating assembly 300, which is arranged in the unfolding direction of each storage assembly 100, and is suitable for starting timing for the air bag group after the air flow distribution assembly 200 starts supplying air to the air bag group, and stopping timing for the air bag group after being triggered by the corresponding unfolded storage assembly 100.

[0031] The car seat massage air bag inflation detection device is provided with a plurality of storage components 100, which can first store the various air bag groups of a massage air bag, and then the air flow distribution component 200 can constantly supply air to each air bag group to make it expand. The expanded air bag groups will cause the corresponding storage components 100 to unfold, and the speed indicating component 300 can start timing the air bag group after the air flow distribution component 200 starts to supply air to the air bag group, and stop timing the air bag group after being triggered by the corresponding unfolded storage component 100, thereby obtaining the time from the start of inflation to the maximum expansion of each air bag group under constant air supply conditions, and this time can be used to represent the inflation speed of each air bag group. At the same time, the car seat massage air bag inflation detection device can determine the synchronization of the two paired air bag groups by obtaining the time from the start of inflation to the maximum expansion of each air bag group. It can also pair two air bag groups with good synchronization according to the time from the start of inflation to the maximum expansion of each air bag group.

[0032] like Figure 2As shown, the storage assembly 100 may include: a slide rail 110, one side of which is provided with a fixed baffle 120 to form an air bag group storage groove 140 with a slider 130 on the slide rail 110; in at least one embodiment, a certain distance is reserved between the slider 130 and the fixed baffle 120 to facilitate the insertion of the air bag group into the air bag group storage groove 140; a reset member 150, one end of which is connected to the slider 130 and the other end is connected to the reset base 160, so that when the air bag group expands and pushes the slider 130 toward the reset base 160, and then loses air supply, the slider 130 is pushed back to its original position.

[0033] like Figure 2 and Figure 6 As shown, the speed indicator assembly 300 may include: a position sensor 310 electrically connected to the control module and positioned in the direction in which the slider 130 is pushed out. The position sensor 310 is configured to send a trigger signal to the control module when the slider 130 is triggered by the expansion of the airbag assembly. The control module is electrically connected to the airflow distribution assembly 200 and is configured to start timing the airbag assembly after the airflow distribution assembly 200 begins supplying air to the airbag assembly, and to stop timing the airbag assembly after receiving the trigger signal. In at least one embodiment, the control module is a PLC module, and the timing can be displayed on an industrial control screen.

[0034] In at least one embodiment, the position sensor 310 is a proximity switch, which is disposed next to the reset base 160 and is adapted to be triggered by the slider 130 when the airbag assembly is inflated to the maximum.

[0035] like Figure 2 As shown, lateral baffles 170 may be further provided on both sides of the slide rail 110 to ensure that the air bag assembly pushes the slider 130 when inflated.

[0036] In at least one embodiment, Figure 2 As shown, the reset member 150 is a spring, and the elastic force of the selected spring is much smaller than the thrust when the air bag group is inflated, and it can push the slider 130 back after the air bag loses air supply.

[0037] like Figure 3 and Figure 5As shown, the airflow distribution assembly 200 may include: a plurality of air valves 210, each corresponding to a receiving assembly 100, and each air valve 210 is electrically connected to the speed indicating assembly 300; in at least one embodiment, the air valve 210 can be electrically connected to the control module in the speed indicating assembly 300; and an adapter 220, on which are provided a plurality of pairs of air valve docking nozzles 221 and air bag assembly docking nozzles 222 corresponding to the air valves 210, and each pair of air valve docking nozzles 221 is connected to the air bag assembly docking nozzle 222. The air valve docking nozzle 221 can be connected to the corresponding air valve 210 via an air pipe. The provision of the air bag assembly docking nozzle 222 makes it convenient to directly insert the air pipe on the air bag assembly into the air bag assembly docking nozzle 222 during testing, thereby connecting to the corresponding air valve 210.

[0038] like Figure 3 As shown, the air bag group docking nozzles 222 can be arranged in a row on the adapter 220, and an anti-error protrusion 223 is provided next to the air bag group docking nozzles 222. The air pipes of the air bag group on a massage air bag are usually tied together to form a multi-row socket. Arranging the air bag group docking nozzles 222 in a row can facilitate plugging during testing. In at least one embodiment, as Figure 3 As shown, two air bag groups have docking nozzles 222 arranged in a row, and another three air bag groups have docking nozzles 222 arranged in a row, which is suitable for testing massage air bags with five air bag groups, wherein the anti-error protrusion 223 can prevent air supply problems caused by reverse insertion.

[0039] In at least one embodiment, the gas valve 210 is a solenoid valve, which can be connected to, for example, a pressure stabilizing device, so as to provide a constant gas supply after being opened.

[0040] like Figure 4 As shown, the storage components 100 can also be placed in pairs on the detection seat 400. In this way, after the air bag groups of the two massage air bags are placed in the corresponding storage components 100, the air bag groups of the two massage air bags correspond one by one from top to bottom on the detection seat 400, which can correspond to the timing displayed in the speed display component 300. It can more intuitively see the time from the start of inflation to the maximum expansion of each air bag group under constant air supply conditions, that is, the inflation speed of each air bag group, and more intuitively see the synchronization of the two paired air bag groups. Figure 4For example, ten storage assemblies 100 can be symmetrically arranged on the left and right sides of the detection seat 400, and the time display areas on the industrial control screen used to display the timing in the speed display assembly 300 are usually also distributed from top to bottom on the screen, so that the two correspond to each other. Correspondingly, the air flow distribution assembly 200 can also be arranged on the left and right sides to facilitate the insertion of the air pipes of the air bag group. When ten storage assemblies 100 are set, the massage air bag with five air bag groups can be tested. The air bag groups of two five-air bag massage air bags are placed in the left and right storage assemblies 100 respectively for testing. The time displayed in the time display area on the industrial control screen used to display the timing in the speed display assembly 300 corresponds to each air bag group, and the time difference between the two time display areas at the same height corresponds to the synchronization of the two paired air bag groups.

[0041] To sum up, the car seat massage air bag inflation detection device is provided with a plurality of storage components 100, which can first store the various air bag groups of a massage air bag, and then the air flow distribution component 200 can constantly supply air to each air bag group to make it expand. The expanded air bag groups will cause the corresponding storage components 100 to unfold, and the speed indicating component 300 can start timing the air bag group after the air flow distribution component 200 starts to supply air to the air bag group, and stop timing the air bag group after being triggered by the corresponding unfolded storage component 100, thereby obtaining the time from the start of inflation to the maximum expansion of each air bag group under constant air supply conditions, and this time can be used to represent the inflation speed of each air bag group. At the same time, the car seat massage air bag inflation detection device can determine the synchronization of the two paired air bag groups by obtaining the time from the start of inflation to the maximum expansion of each air bag group. It can also pair two air bag groups with good synchronization according to the time from the start of inflation to the maximum expansion of each air bag group.
