[0023] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects:
[0024] The vehicle seat system function verification device includes: a relay coil, a first switch, a first overload protection module, a second switch, and an output module. The first end of the relay coil is connected to the positive terminal of the DC power supply through the first switch, and the second end of the relay coil is connected to the negative terminal of the DC power supply; the first end of the first overload protection module is connected to the positive terminal of the DC power supply, the second end of the first overload protection module is connected to the first end of the second switch, and the relay coil is linked with the second switch; the input ends of the output module are respectively connected to the second end of the second switch and the second end of the relay coil, and the output end of the output module is used to connect to an external seat system to be tested.
[0025] In this solution, the docking harness plug of the seat system is connected to the DC power supply through the output module.

[0045] It should be noted that all actions of obtaining signals, information, or data in this application are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where the location is located and obtaining authorization from the corresponding device owner.
[0046] In the related art, during the vehicle seat system function verification process, a 12V battery is usually used as the verification device. First, manually connect the seat docking harness plug to the positive and negative electrode posts of the 12V battery, and then adjust the seat switch to verify the seat function. When the seat docking harness plug is connected to the positive and negative electrode posts of the 12V battery, electric sparks are easily generated, which can easily cause electric burns to the hands of production personnel. Moreover, since the seat docking harness plug is directly connected to the 12V, when the current between the seat controller and the power supply circuit is too large, the seat controller is easily damaged. At the same time, when production personnel connect the positive and negative electrode posts of the 12V battery to the seat docking harness plug, it is not easy to distinguish the positive and negative poles, which affects the work efficiency and work quality.
[0047] Figure 1 is a schematic diagram of a vehicle seat system function verification device shown according to an exemplary embodiment. As Figure 1 shown, the verification device 100 includes a relay coil 1, a first switch 2, a first overload protection module 3, a second switch 4, and an output module 5.
[0048] The first end 1a of the relay coil 1 is connected to the positive terminal of the DC power supply through the first switch 2, and the second end 1b of the relay coil 1 is connected to the negative terminal of the DC power supply;
[0049] The first end 3a of the first overload protection module 3 is connected to the positive terminal of the DC power supply, the second end 3b of the first overload protection module 3 is connected to the first end 4a of the second switch 4, and the relay coil 1 is linked with the second switch 4;
[0050] The input ends of the output module 5 are respectively connected to the second end 4b of the second switch 4 and the second end 1b of the relay coil 1, and the output end of the output module 5 is used to connect to the external seat system to be tested.
[0051] The first switch 2 is a normally open switch. Exemplarily, the first switch 2 can be a manual switch (such as a single-pole single-throw switch, a push-button switch), or an automatic switch (such as a relay).
[0052] The first overload protection module 3 is used to protect the verification device 100 and the seat system to be tested. In the case of a large current existing in the circuit for a long time due to a long motor stall time of the seat system to be tested or a power short circuit, etc., the first overload protection module 3 opens itself to cut off the power supply of the circuit between the seat system and the verification device 100.
[0053] The relay coil 1 is linked with the second switch 4, and the second switch 4 is a normally open switch.
[0054] The DC power supply can be, for example, any type of DC power supply, which is not limited herein. Exemplarily, the DC power supply can be a 12V DC power supply composed of six 18650 lithium-ion batteries. Every three batteries are connected in series to form a group, and two groups are connected in parallel. In this way, the output voltage reaches 12V after three 18650 lithium-ion batteries are connected in series, and the two lithium-ion battery packs are connected in parallel, and the battery capacity of the DC power supply reaches 5000 mAh. If the working current of a single seat system is 10A, the number of seat systems that each DC power supply can continuously verify at a time can reach fifteen.
[0055] The output module 5 is used to connect the verification device 100 and the seat system to be tested. Before verifying the seat system to be tested, the production personnel connect the output end of the output module 5 in the verification device 100 to the docking harness plug of the external seat system to be tested. During the verification process, the first switch 2 is controlled to close, the relay coil 1 is powered on, the second switch 4 linked with the relay coil 1 closes, the circuit between the DC power supply, the first overload protection module 3, the output module 5 and the external seat system to be tested is conducted, the seat system to be tested is powered on, and thus the production personnel adjust the seat system switch to conduct the function verification.
[0056] In this solution, the docking harness plug of the seat system is connected to the DC power supply through the output module. In this way, when the seat system is manually connected to the verification device, the docking harness plug of the seat system does not directly contact the positive and negative power terminals, thus avoiding the generation of electric sparks and improving safety. Moreover, the first overload protection module in this solution can open the circuit when there is a large current in the loop for a long time. During the verification process, after the first switch is closed, the relay coil is powered on, and the second switch linked to the relay coil is closed, and the loop between the DC power supply, the first overload protection module and the seat system is conducted. In this way, by setting the first overload protection module, even if the seat system has a large current in the loop for a long time due to a long motor blocking time or a power short circuit, the first overload protection module can open the circuit in time, so as to protect the harness and the seat controller in time, improve safety, and reduce the verification cost during vehicle trial production.
[0057] Figure 2 is a schematic diagram of a vehicle seat system function verification device shown according to another exemplary embodiment. As Figure 2 shown, the first overload protection module 3 includes a slow-blow fuse.
[0058] The first overload protection module 3 can be, for example, a slow-blow fuse. The slow-blow fuse can include multiple specifications, for example, it can be a 30A slow-blow fuse. When there is a current exceeding 30A in the loop between the DC power supply, the slow-blow fuse and the seat system to be tested for a long time, the slow-blow fuse opens the circuit.
[0059] In this embodiment, the slow-blow fuse remains intact when encountering a non-fault large current, and at the same time plays a role in protecting against long-term large current overload. Using the slow-blow fuse as the first overload protection module, the circuit is simple and the reliability is high.
[0060] In yet another embodiment, the verification device 100 further includes a second overload protection module 6.
[0061] The second overload protection module 6 is connected in series with the relay coil 1.
[0062] The second overload protection module 6 is used to protect the loop between the DC power supply, the second overload protection module 6 and the relay coil. The second overload protection module 6 opens the circuit when there is a large current in the loop between the DC power supply, the second overload protection module 6 and the relay coil, so that the loop is powered off.
[0063] In this embodiment, by setting the second overload protection module in the verification device, it is possible to prevent the relay coil from short-circuiting to the negative pole of the DC power supply, burning out the circuit wires, damaging the DC power supply, and improving safety.
[0064] The second overload protection module 6 can be connected in series at any position in the loop where the relay coil 1 and the DC power supply are located. Exemplarily, refer to Figure 2 , in another embodiment, the second overload protection module 6 is connected in series between the first end 1a of the relay coil 1 and the first switch 2. Figure 3 FIG. is a schematic diagram of a vehicle seat system function verification device shown according to another exemplary embodiment. Refer to Figure 3 , in another embodiment, the second overload protection module 6 is connected in series between the second end 1b of the relay coil 1 and the negative terminal of the DC power supply.
[0065] In another embodiment, the second overload protection module 6 includes a blade fuse.
[0066] The second overload protection module 6 can be, for example, a blade fuse. The blade fuse can include multiple specifications, for example, it can be a 5A blade fuse.
[0067] In this embodiment, using the blade fuse as the second overload protection module, the circuit is simple and the reliability is good.
[0068] Continue to refer to Figure 2 , in another embodiment, the verification device 100 further includes a voltmeter 7.
[0069] The second end 1b of the voltmeter 7 relay coil is connected to the negative terminal of the DC power supply through the voltmeter 7.
[0070] The voltmeter 7 is used to detect the real-time voltage of the DC power supply to ensure the normal operation of the verification device 100. Exemplarily, after the first switch 2 is closed, first, the display value of the voltmeter 7 can be observed. If the voltmeter 7 has no display and the relay coil 1 does not act, check whether the first overload protection module 3 is open. Exemplarily, after the first switch 2 is closed, if the voltmeter 7 has no display and the relay coil 1 acts, check whether the second overload protection module 6 is open; if the second overload protection module 6 is not open and the seat moves after adjusting the seat switch, check whether the voltmeter 7 is damaged.
[0071] In this embodiment, by setting a voltmeter in the verification device, the DC power supply voltage can be monitored in real time, which is convenient for the staff to timely determine the fault type and take corresponding measures.
[0072] In another embodiment, the output module 5 includes a first banana plug 8 and a second banana plug 9.
[0073] The first end 8a of the first banana plug 8 and the first end 9a of the second banana plug 9 are the input ends of the output module 5, and the second end 8b of the first banana plug 8 and the second end 9b of the second banana plug 9 are the output ends of the output module 5;
[0074] The first end 8a of the first banana plug 8 is connected to the second end 4b of the second switch 4, and the first end 9a of the second banana plug 9 is connected to the negative terminal of the DC power supply.
[0075] The first banana plug 8 can be, for example, a red banana plug, and the second banana plug 9 can be, for example, a black banana plug.
[0076] In this embodiment, the first banana plug and the second banana plug are used as the output module, and the circuit is simple and convenient for production personnel to distinguish the positive and negative poles of the DC power supply.
[0077] Figure 4 It is a schematic diagram of a vehicle seat system function verification device shown according to another exemplary embodiment. As Figure 4 shown, the verification device 100 further includes a housing 10 and a base 11.
[0078] The DC power supply is disposed in the sealed space formed by the housing 10 and the base 11.
[0079] A sealed space is formed between the housing 10 and the base 11, and the DC power supply can be disposed at any position within this sealed space to protect the DC power supply.
[0080] The connection manner between the housing 10 and the base 11 can be, for example, bolt connection. In this way, it is convenient to open when repairing the verification device 100 or replacing the DC power supply.
[0081] In another embodiment, at least one of the relay coil 1, the first switch 2, the first overload protection module 3, the second overload protection module 6, the voltmeter 7, the first banana plug 8, and the second banana plug 9 is disposed on the surface of the housing 10.
[0082] At least one of the relay coil 1, the first switch 2, the first overload protection module 3, the second overload protection module 6, the voltmeter 7, the first banana plug 8, and the second banana plug 9 can be disposed on the upper surface and / or any side surface of the housing 10.
[0083] For example, the relay coil 1 and the first switch 2 can be disposed on the upper surface of the housing 10, and the first overload protection module 3, the second overload protection module 6, the voltmeter 7, the first banana plug 8, and the second banana plug can be disposed on any side surface of the housing 10.
