It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] Please refer to Figure 1-3 The present invention provides a piece of clothing for a car collision dummy, comprising:

[0048] A clothing body 1, wherein the clothing body 1 is used to be mounted on a dummy 2 and used in conjunction with a capacitive sensor mounted on a car seat so that the capacitive sensor can detect the dummy 2; the capacitive sensor is electrically connected to a car cabin structure 24 and has an equal potential, or is artificially set to have an equal potential to the car cabin structure 24;

[0049] The clothing body 1 comprises:

[0050] The conductive part 3 has a conductive property;

[0051] A grounding component 4 , wherein the grounding component 4 is electrically connected to the conductive part 3 .

[0052] Specifically, the clothing body 1 is provided with a conductive part 3, and the conductive part 3 is electrically connected to the vehicle cabin structure 24 through a grounding component 4, and the potentials are kept equal.

[0053] The clothing body 1 with the conductive part 3 is first worn on the dummy 2 to be tested, and then the dummy 2 to be tested is placed on the seat to be tested, and the conductive part 3 is electrically connected to the grounding component, and the grounding component 4 is electrically connected to the car cabin structure 24. The car cabin structure 24 includes the car body and the car seat 12.

[0054] This method can make the clothing body 1 on the dummy and the control module 18 (ECU) of the capacitive sensor form an equipotential relationship, so that the capacitive sensor can be used to detect the test dummy 2 when the vehicle is subjected to a collision test.

[0055] Furthermore, the conductive portion 3 at least covers the buttocks and thighs of the dummy 2 .

[0056] Furthermore, the conductive part 3 is made of metal cloth, graphene film, or woven cloth with metal wires.

[0057] Specifically, the capacitive sensor includes: at least one first detection electrode 20 , a connecting harness 19 and a control module 18 .

[0058] The first detection electrode 20 is at least disposed on the seat cushion of the vehicle seat 12 , and may also be disposed on the backrest of the vehicle seat 12 .

[0059] When the dummy is placed on the seat, the buttocks and thighs of the dummy 2 are in contact with the seat cushion, and the back of the dummy may be in contact with the backrest. The conductive part 3 at least covers the buttocks and thighs of the dummy 2, ensuring that an electric field exists between the conductive part 3 and the first detection electrode 20. The clothing body 1 can be entirely composed of the conductive part 3, so that the capacitive sensor can detect the dummy 2 through the clothing body 1, with higher reliability.

[0060] When the dummy 2 for testing is of child size, a child seat 21 is also provided on the car seat 12; a capacitive sensor is also installed on the child seat 21. The capacitive sensor also includes a second detection electrode 22. A plurality of second detection electrodes 22 are respectively provided on the side of the child seat 21 close to the occupant and the side close to the car seat 12, and the second detection electrodes 22 on both sides are electrically connected through a connecting conductor 25, that is, the second detection electrodes 22 on both sides are of equal potential. The second detection electrode 22 cooperates with the conductive part 3 to enable the capacitive sensor to detect the dummy 2 of child size.

[0061] Further, refer to Figure 4-10 , the clothing body 1 further comprises: a covering layer 23;

[0062] The coating layer 23 comprises:

[0063] The first substrate layer 11 is sleeved on the dummy 2 ; the conductive part 3 is installed on the first substrate layer 11 .

[0064] In some embodiments, the covering layer 23 completely wraps the dummy 2 , or only covers the buttocks and thighs of the dummy 2 , and the area of ​​the covering layer 23 is greater than or equal to the area of ​​the conductive portion 3 .

[0065] Furthermore, the conductive part 3 is installed on a side of the first substrate layer 11 close to the dummy or on a side away from the dummy.

[0066] Specifically, the conductive part 3 and the detection electrode of the capacitive sensor are close to each other and face each other, so that the capacitive sensor can detect the conductive part 3 and thus know the existence of the dummy 2. Therefore, the conductive part 3 can be arranged on the side of the first substrate layer 11 close to the dummy or away from the dummy.

[0067] In some embodiments, the conductive part 3 is installed on the surface of the first substrate layer 11; or a mounting hole is opened on the surface of the first substrate layer 11, and the conductive part 3 is installed in the mounting hole, and the edge of the conductive part 3 is fixedly connected to the edge of the mounting hole.

[0068] Furthermore, the conductive part 3 and the first substrate layer 11 are fixed to each other by gluing or sewing.

[0069] Furthermore, the coating layer 23 further includes: a second substrate layer 17;

[0070] The conductive part 3 is installed between the first substrate layer 11 and the second substrate layer 17. In order to reduce the probability of damage to the conductive part 3 during the test, in some embodiments, the clothing body 1 is provided with two substrate layers. The conductive part 3 is provided between the substrate layers on both sides.

[0071] Furthermore, the conductive part 3 is a metal wire, the first substrate layer 11 is a woven cloth, and the conductive part 3 is woven on the first substrate layer 11 .

[0072] The electrodes of the capacitive sensor corresponding to the conductive part 3 can be made of conductive materials such as metal wire, metal cloth, metal mesh, graphite film, etc.

[0073] Further, refer to Figure 11-15 ;

[0074] The grounding component 4 comprises:

[0075] A wiring portion, the wiring portion is mounted on the conductive portion 3 and is electrically connected to the conductive portion 3;

[0076] A wiring harness assembly 6, wherein the wiring harness assembly 6 has a first terminal 7 and a second terminal 8;

[0077] The first terminal 7 is connected to the wiring portion and electrically connected to the conductive portion 3 ; the second terminal 8 is used to connect to the vehicle cabin structure 24 to make the conductive portion 3 and the control module 18 of the capacitive sensor have the same potential.

[0078] In some embodiments, the first wiring terminal 7 is detachably connected or fixedly connected to the wiring portion.

[0079] Furthermore, the wiring portion is a socket 5, and the socket 5 is detachably connected to the first wiring terminal 7 by means of magnetism, snap or latch.

[0080] In some embodiments, the socket 5 is installed on the first substrate layer 11 so that the conductive part 3 and the car cabin structure 24 are at the same potential before the car collision test by installing the wiring harness assembly 6 on the socket 5. At the same time, since the first detection electrode 20 is electrically connected to the control model (ECU) through the connecting harness 19, the control module 18 (ECU) is electrically connected to the car cabin structure 24 to be at the same potential or is set to be at the same potential as the car cabin structure 24 by a human program. Finally, the clothing body on the dummy and the capacitive sensor can form an equipotential relationship.

[0081] The connection method between the wiring harness assembly 6 and the socket 5 includes:

[0082] First embodiment, reference Figure 10-11 :

[0083] The socket 5 is provided with a first permanent magnet 9; the first terminal 7 is made of a metal material; the first terminal 7 can be attracted by a magnetic field;

[0084] When the first wiring terminal 7 is mounted on the socket 5 , the magnetic field of the first permanent magnet 9 attracts the first wiring terminal 7 .

[0085] The first permanent magnet 9 and the first terminal 7 are attracted to each other to fix the position of the wiring harness assembly 6 and the socket 5, so as to ensure that an electrical connection can be established between the two. This connection method is simple and convenient to disassemble.

[0086] In some embodiments, reference Fig.12 The first terminal 7 is attracted to the first permanent magnet 9 by installing a metal block 10, so that the wiring harness assembly 6 is electrically connected to the socket 5.
