Detailed Implementation Methods

[0014] To reduce costs during development, simulation testing, and other processes, this patent proposes using water pipes to create the dummy's skeleton and chassis, then supplementing it with foam or sponge to cushion impact forces, and finally dressing it in clothing to complete the dummy. The following detailed examples illustrate this.

[0015] Example 1: A dummy used as a target for assisted driving in this example, particularly a dummy used as a target for automatic emergency braking in a car. See [link to example]. Figure 1 , 2 As shown in Figure 3, it includes: a dummy skeleton 1, a base 2 located at the bottom of the dummy skeleton 1, and a cushioning material 3 filled on the dummy skeleton 1; a support water pipe 11 connected to the lower body of the dummy skeleton 1, a leg water pipe 12 of the dummy skeleton, and a connecting pipe 21 connected in the vertical direction to the base 2.

[0016] The dummy skeleton 1 has a human skeletal structure, and supporting water pipes 11 are connected to its lower body. The base 2 has a stable support structure, specifically including but not limited to a cross shape, fishbone shape, square shape, or rectangle, and connecting pipes 21 in the vertical direction corresponding to the number and diameter of the leg water pipes 12 and supporting water pipes 11 of the dummy skeleton. During assembly, the leg water pipes 12 and supporting water pipes 11 of the dummy skeleton 1 are inserted into the corresponding connecting pipes 21.

[0017] Before constructing the dummy in this embodiment, it is necessary to determine the approximate dimensions of the dummy and the approximate length of the skeleton for each part. Based on actual experimental requirements, the dummy height can be set independently, and the dimensions of each part can be selected, with the height directly referencing the actual height of a real person and the proportions of each part. After cutting all the water pipes, cut the shoulder water pipes into four sections, one long and one short, for a total of two groups. Connect the two ends of the long section with a T-joint. Connect one end to the short section and the chest water pipe, and the other end to the water pipe at the neck. Connect the other group symmetrically to this group using a T-joint. After connecting the joints, secure them at the T-joint interfaces with glue, thread, or screws. At the outer end of the shoulder, connect the hand water pipe using a bent connector and secure it. When connecting the bent connector, pay attention to the hand's swing angle. The construction of the waist water pipe is similar to that of the shoulder water pipe, but it needs to be cut into five sections. The longest section is connected at both ends with a T-joint, then connected to the lower body support water pipe 11 and another section of the waist water pipe. The waist water pipe is then connected to the chest water pipe with a T-joint, and then connected to the outer end of the waist water pipe. The outer end of the waist water pipe is connected with a bent connector, and then connected to the leg water pipe and secured with glue or screws. When connecting the leg water pipe 12, attention should be paid to the angle, and it should coordinate with the hand water pipes to create a swaying walking motion. Finally, a T-joint is connected to the upper end of the neck water pipe, connecting to the head water pipe. The head water pipe is then connected to each side with bent connectors. Note that the T-joints and bent connectors also have lengths; these lengths must be factored in during cutting to avoid disproportion due to different connectors.

[0018] The base 2 has water pipes of equal length and dimensions, requiring the connection of four water pipes: the leg pipes 12 and the lower body support pipes 11. First, select two water pipes as connecting pipes 21 and attach curved connectors, then slip them onto the dummy support pipes 11. Next, connect the other ends of the two connecting pipes 21 with T-joints, connecting one section of water pipe to one end of each of the two T-joints and securing them with glue or screws. At the outer end of the connected T-joints, connect two more sections of connecting pipe 21 and the T-joint, respectively connecting them to the dummy's leg pipes 12. Then, connect two more sections of water pipe into the T-joints, forming a cross shape to increase the surface area and prevent the base with the dummy from tipping over.

[0019] After the dummy skeleton is completed, fill it with cushioning material 3. Cushioning material 3 can be made of foam, sponge, air bags, etc. First, fill the chest. Tie rectangular cushioning material to the two water pipes in the chest and secure it with tape or rope. The chest filling material needs to be thick enough, and the abdominal area can be larger so that it looks more human when dressed. Next, use cylindrical cushioning material with a hole in the middle and insert it into the four water pipes of the hands and legs, and secure it with tape or rope. The hands and legs can also be made with sheet-like cushioning material, which is wrapped around the water pipes of the hands and legs. In this step, it is important to note that the shape of the legs is different from the top to the bottom. Do not use straight cylinders. It needs to be made into a leg shape that is thicker at the top and thinner at the bottom so that it looks more like a real human body when wearing pants. Finally, fill the head. Note that the neck also needs to be filled. The head filling can be done by wrapping cushioning material on both sides. Again, pay attention to the shape of the face. It cannot be made into a square. From the side, it should be a rectangle that is longer vertically and horizontally, and from the front and back, it should have a circular shape.

[0020] In practical implementation, the height of the dummy can be set according to the requirements of actual experiments. The dimensions of each part of the dummy can be selected, and the height can be directly referenced to the actual height of a real person and the proportions of each part, such as a height of 120-180cm. For example, if the head and neck are 20cm high, the legs are 75cm long, and the upper body is 65cm long, the resulting dummy skeleton will be 160cm tall with arms 55cm long. Adding head padding, the dummy's height will be approximately 165cm. The following will explain the dummy's construction in detail using this height as an example; other heights are similar. After selecting the height, subtract approximately 5cm of padding thickness based on the body width to set the shoulder width, chest width, and leg width. For example, the shoulder width can be set to 50cm, the chest width to 45cm, and the leg width to 49cm. To make the dummy stand upright, in addition to the leg skeleton as support, lower supports need to be added to form multiple supports, making the dummy more stable. The lower supports can be one or two water pipes; if using two water pipes, two 38cm wide lower supports can be selected. Because the automatic emergency braking function operates when pedestrians cross the road, and the camera detects the dummy from the side and side of the face, the head needs to be widened from the side. The head is made into a square or cross-shaped frame in the front and back direction of the side dummy, with a length of 14cm.

[0021] After determining the height and length of each part of the dummy, cut the prepared water pipes to the corresponding lengths. Connect the different parts of the water pipes using elbows or tee connectors. Glue or self-tapping screws can be used at the joints. Pay attention to the angles of the hands and legs during connection. Additionally, pipe bending springs can be used to bend the water pipes at specific angles. After all connections to the water pipes are complete, note the lengths of the legs and supports; further cutting and alignment may be necessary depending on the situation.

[0022] To allow the dummy to stand, a 4A-certified dummy base can be used, or a homemade base made of water pipes can be used. To make a homemade water pipe base, after constructing the dummy's skeleton, create a roughly rectangular base using water pipes to support the legs and lower body. The width corresponds to the relative positions of the supports and legs, while the length can be adjusted as needed. For example, the supporting pipe should be 60cm long, the pipe connecting to the leg facing the impact should be approximately 28cm long, and the pipe connecting to the non-impact leg should be 75cm long. Connect the base and the dummy using water pipe connectors to support the dummy's standing position. To facilitate the dummy's detachment from the base during a collision, simply use connectors to fit the dummy into the base; screws or glue are not required.

[0023] After the dummy skeleton is completed, it is filled with cushioning material, such as foam, sponge, or air bags. First, the chest is filled. Rectangular cushioning material is tied to the two water pipes in the chest, front and back, and secured with tape or rope. The chest filling needs to be thick enough, while the abdominal area can be larger to make it more human-like when dressed. Next, cylindrical cushioning material with a hole in the center is inserted into the four water pipes for the hands and legs, and secured with tape or rope. Sheet-like cushioning material can also be used for the hands and legs, wrapped around the water pipes. It's important to note that the legs should have a slightly different shape from top to bottom; avoid using straight cylinders. They need to be made with a shape that is thicker at the top and thinner at the bottom to resemble a real human when dressed in pants. Finally, the head is filled. Note that the neck also needs some filling. Cushioning material can be tied to the sides of the head. Again, attention must be paid to the side profile; it shouldn't be square. From the side, it should be a longer rectangle, while from the front and back, it should have a rounded shape.

[0024] After filling in the cushioning material, dress the dummy in human clothing. The clothing should ideally be durable, brightly colored, and clearly contrast with the background color used in the experiment. It's best to avoid clothing with patterns like checks or other multi-faceted designs. Since the lower body has supporting water pipes, the pants need to have a hole cut in the corresponding area to allow the pipes to pass through. The head can be wrapped in white clothing, and the hair area can be sprayed with black paint; alternatively, a side view can be printed out and pasted onto the side of the head.
