[0032] Comfort is a crucial indicator in the field of product design, especially in the design of wearable products. When head or facial wearable products are in direct contact with the human body, they will exert a certain amount of pressure on the skin, and pressure distribution is one of the key factors affecting comfort. In order to test and adjust the pressure distribution of wearable products during the R&D stage, a bionic head model is generally prepared that meets the average size requirements of the corresponding population of the product as a reference for wearing.

[0033] For wearable products for children, children's bionic head molds are naturally used as model references to design and adjust wearable products. Moreover, compared with adults, children are still in the growth and development period, and their skin is delicate and easily susceptible to pressure injuries, so there are higher requirements for bionic head molds.

[0034] At present, there are corresponding children's head models on the market, and there are relevant standards for the specific sizes of children's head models for standardized management. However, compared with adults, children also have another characteristic that they often engage in physical activities and have a lower tolerance for wearable products. If wearable products pull and restrict children during activities, children may feel uncomfortable. Current children's head models are generally just static models, and do not simulate and imitate children's various physical activities, so wearable products lack testing in children's activity scenarios.

[0035] In this regard, the present application proposes a children's bionic head model, which can drive the head body 210 to pitch through an electric telescopic rod 400 to simulate the effect of the pitch of a child's head, and simulate the effect of the opening and closing of the child's lower jaw through a mandibular driving component 500, thereby simulating the child's physical activities and providing a more comprehensive model reference for head-mounted wearable products.

[0036] Reference Figure 1The child bionic head model in the embodiment of the present application includes a base 100, a bionic skull 200, a support rod 300, an electric telescopic rod 400 and a mandibular drive assembly 500. The base 100 is used as a fixed structure of the child bionic head model, which can be connected to an external bionic platform; the bionic skull 200 is used to simulate the child's skull; the support rod 300 is used to support the bionic skull 200; the electric telescopic rod 400 is used to drive the bionic skull 200 to pitch to simulate the child's lowering and raising of the head; the mandibular drive assembly 500 is used to control the opening and closing of the mandible to simulate the child's opening and closing of the mouth.

[0037] Specifically, the bionic skull 200 includes a skull body 210, a lower jaw 220 and a skull fixing part 230. The skull body 210 mainly simulates a child's skull, and its interior is hollow to reduce its own weight. The skull fixing part 230 is installed inside the skull body 210 as a connecting part with the support rod 300 and the electric telescopic rod 400. The lower jaw 220 is hinged to the bottom of the skull body 210, and it can be flipped around the hinge axis, thereby simulating the opening and closing action of the child's lower jaw.

[0038] Further, for the connection method between the head fixing piece 230 and the head body 210. In some embodiments, the head fixing piece 230 is connected to the head body 210 by bolts. In other embodiments, the head fixing piece 230 is connected to the head body 210 by buckles. In this embodiment, a groove 211 is provided inside the head body 210, and the head fixing piece 230 is in the shape of a plate as a whole, and its edge can be snapped into the groove 211 to complete the limiting and fixing, so that the head fixing piece 230 is snapped with the groove 211.

[0039] The first end of the support rod 300 is fixedly connected to the base 100, and the second end of the support rod 300 is hinged to the head fixing part 230, so that the support rod 300 can not only support the bionic head 200, but the bionic head 200 can also flip over with the hinge of the support rod 300 as a fulcrum to achieve the pitch change of the bionic head 200.

[0040] Furthermore, in the present embodiment, there are two support rods 300 arranged side by side, and the two support rods 300 are connected to the head fixing member 230 together, thereby providing more stable support for the bionic head 200 and preventing the bionic head 200 from falling over.

[0041] Furthermore, a universal joint 310 is installed at the second end of the support rod 300, so that the calibration and adjustment of the hinge direction of the support rod 300 can be avoided during assembly, saving assembly process and improving assembly efficiency.

[0042] The two ends of the electric telescopic rod 400 are respectively hinged to the base 100 and the head fixing part 230. The head fixing part 230 can be lifted up or pulled down by the extension of the electric telescopic rod 400. Since the head fixing part 230 is hinged to the support rod 300, based on the lever principle, the bionic head 200 can lower or raise its head due to the extension of the electric telescopic rod 400.

[0043] refer to Figure 3 The mandibular drive assembly 500 includes a servo 510 and a rocker 520. The servo 510 is installed on the skull fixing part 230. One end of the rocker 520 is fixedly connected to the output shaft of the servo 510. The other end of the rocker 520 drives the mandibular 220 to flip, thereby realizing the opening and closing of the mandibular 220.

[0044] Furthermore, the present child bionic head model further comprises a rotating head assembly 600, referring to Figure 2 The head turning assembly 600 includes a motor 610, and the output shaft of the motor 610 is connected to the base 100 to drive the base 100 to rotate, thereby simulating the action of a child turning his head.

[0045] Furthermore, the rotor assembly 600 further includes a protective shell 620 and a fixing seat 630. The protective shell 620 is in a shell shape with a space inside, the fixing seat 630 is installed inside the protective shell 620, and the motor 610 is installed inside the protective shell 620 through the fixing seat 630, and the protective shell 620 is used to protect the motor 610.

[0046] Furthermore, the rotor assembly 600 also includes a bearing 640, which is installed between the protective shell 620 and the base 100. The base 100 applies pressure to the protective shell 620 through the bearing 640. On the one hand, it is used to reduce the relative rotational resistance between the base 100 and the protective shell 620, and on the other hand, it prevents the base 100 from applying pressure directly to the output shaft of the motor 610, thereby extending the service life of the motor 610.

[0047] Furthermore, the rotating head assembly 600 also includes a gear set 650, and the motor 610 is connected to the base 100 through the gear set 650, so that the gear ratio is changed through the gear set 650 to reduce the torque requirement of the motor 610. Specifically, the gear set 650 includes a large gear and a small gear, the small gear is connected to the output shaft of the motor 610, and the large gear is connected to the base 100. The number of teeth of the large gear is greater than the number of teeth of the small gear, and the two are meshed with each other. The output torque of the motor 610 can be amplified by such a gear combination.

[0048] Further, with regard to the specific driving mode of the mandibular drive assembly 500, the mandibular drive assembly 500 further includes a first connecting rod 530 and a second connecting rod 540. The other end of the rocker 520 is pivotally connected to one end of the first connecting rod 530, the other end of the first connecting rod 530 is pivotally connected to one end of the second connecting rod 540, and the other end of the second connecting rod 540 is fixedly connected to the mandibular 220. Thus, the rocker 520, the first connecting rod 530 and the second connecting rod 540 constitute a multi-link mechanism, and when the rocker 520 is driven by the steering gear 510 to rotate, it can drive the second connecting rod 540 to move, thereby driving the mandibular 220 to rotate.

[0049] In addition, the first connecting rod 530 is a telescopic rod with a retractable length, and the opening and closing range of the mandible 220 can be adjusted by changing the length of the first connecting rod 530. The first connecting rod 530 specifically includes two parts connected to each other by threads. After the first connecting rod 530 is removed separately, the overall length of the first connecting rod 530 can be changed by screwing the two parts, and then the adjusted first connecting rod 530 can be reinstalled.

[0050] Furthermore, the head body 210 is an elastic member used to simulate the skin of a child. A plurality of sensors are embedded inside the head body 210 to detect the pressure values ​​of various parts of the head body 210 after the product is worn, thereby quantifying and analyzing the comfort of the wearable product.

[0051] Specifically, refer to Figure 4 The head body 210 has 10 measurement points on the face, namely: nose bridge A, top of right cheek B, top of left cheek C, middle of right cheek D, middle of left cheek E, bottom of right cheek F, bottom of left cheek G, chin H, back of right auricle I and back of left auricle J. The sensor is embedded in the divided soft tissue, covering the face and auricle, and can make a comprehensive judgment and analysis of the pressure situation of children's faces for wearable products.

[0052] Specifically, the sensors are all piezoresistive sensors, model RFP602, and are electrically connected to an external detector through a wire.

[0053] The above is a specific description of the preferred implementation methods of the present application, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present application, and these equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
