For example, headwear (hats, hairpins, etc.), while ensuring fashion, is increasingly valued for its stability and comfort during various activities. Unfortunately, however, there are no head motion devices on the market that can simulate wearing the items to be tested. Utility Model Content

[0003] The purpose of the embodiments of the present application is to provide a motion simulation device to improve the problem that there is no head motion device on the market that can simulate wearing an object to be detected.

[0004] The embodiment of the present application provides a motion simulation device, comprising: a head model and a motion mechanism; the head model is movably connected to the motion mechanism; the head model is used to wear the item to be detected; and the motion mechanism is used to simulate the motion scene of the item to be detected. In the implementation process of the above scheme, the item to be detected is worn on the head model of the motion simulation device, and the motion scene of the item to be detected is simulated using the motion mechanism of the motion simulation device, thereby realizing the motion simulation function of the head movement. Furthermore, through the movably connected head model and the motion mechanism, the head dynamics of the wearer in different motion states, such as walking, running, jumping, shaking head, etc., can be simulated, ensuring that the test results are highly consistent with the actual usage, thereby improving the degree of realistic simulation of the test.

[0005] Optionally, in an embodiment of the present application, the motion mechanism includes a telescopic shaft movably connected to the headform, the telescopic shaft being used to drive the headform to perform telescopic motion. During implementation of the above solution, the telescopic shaft movably connected to the headform and driving the headform to perform telescopic motion enables the headform to simulate forward and backward, up and down, or left and right telescopic movements of the head in various motion states, such as the natural swaying of the head during running or jumping. This improves the authenticity and accuracy of the test and helps evaluate the fit, stability, and comfort of the item under test under various dynamic conditions.

[0006] Optionally, in an embodiment of the present application, the telescopic shaft includes a telescopic rod and a motor; the motor is used to drive the headform to telescope via the telescopic rod. In implementing this solution, by employing a telescopic shaft structure comprising a telescopic rod and a motor, the motor drives the telescopic rod and the headform to telescope. The motor provides precise power output, allowing precise control of the headform's telescopic distance and speed according to preset programs or real-time instructions. This enables automated and refined management of test scenarios, thereby improving test repeatability and accuracy.

[0007] Optionally, in an embodiment of the present application, the motion mechanism further includes a rotating shaft movably connected to the telescopic shaft, the rotating shaft being used to drive the telescopic shaft and the headform to rotate. In implementing the above solution, by adding the rotating shaft to the existing telescopic shaft, movably connected to the telescopic shaft and driving the telescopic shaft and the headform to rotate, the telescopic and rotational functions are effectively combined, enabling the motion mechanism to simulate complex head motion trajectories in three-dimensional space, such as natural movements such as shaking and turning the head, greatly enhancing the realism and comprehensiveness of the motion scenes.

[0008] Optionally, in an embodiment of the present application, a fixing is provided on the rotating shaft, and the fixing is used to cooperate with the rotating shaft to fix the rotation angle of the rotating shaft. In the implementation process of the above scheme, the rotating shaft can be set and locked at any preset angle position through the fixing, so as to achieve precise angle control of the rotational movement of the head model, which is crucial for tests that need to evaluate the performance of the item to be tested at a specific angle, such as simulating the change in the direction of the athlete's line of sight during the game, or detecting the comfort and stability of the head-mounted device at different tilt angles. Furthermore, the use of the fixing ensures a high degree of consistency in the test conditions, so that tests at the same angle can be accurately reproduced, thereby improving the comparability of the experimental data and the reliability of the test results.

[0009] Optionally, in an embodiment of the present application, the motion simulation device further includes a bracket; the motion mechanism is movably connected to the bracket, and the bracket is used to support the motion mechanism and the head model. In the implementation of the above solution, by adding the bracket to the motion simulation device as a supporting base, the entire motion simulation device can be ensured to remain stable during complex motion simulation, preventing the device from tipping over or shifting, thereby ensuring the safety of the test environment and improving the reliability and accuracy of the test results.

[0010] Optionally, in an embodiment of the present application, a scale is provided on the side of the bracket, and a pointer is provided on the telescopic shaft, and the pointer is used to indicate the current rotation angle on the scale. In the implementation process of the above scheme, by providing a scale on the side of the bracket and equipping the telescopic shaft with a pointer to indicate the current rotation angle, the cooperation of the pointer and the scale can intuitively and quickly read the specific rotation angle of the current rotation axis, without the need for additional electronic instruments or complex calculations, thereby improving the convenience and efficiency of the test operation. Furthermore, the precise positioning capability of the scale and the pointer ensures that the same angle condition can be accurately reproduced for each test, which is particularly important for situations where multiple comparative tests at specific angles are required, and helps to improve the accuracy of the test data and the repeatability of the test results.

[0011] Optionally, in an embodiment of the present application, the motion simulation device further includes: a base; the base is fixedly connected to the bracket, and the base is used to support the bracket, the motion mechanism and the head mold. In the implementation process of the above scheme, by adding a base to the motion simulation device, it is fixedly connected to the bracket to jointly support the bracket, the motion mechanism and the head mold, so that the base serves as the base of the device, providing a stable support platform for the entire motion simulation device, significantly enhancing the stability and vibration resistance of the device when performing various dynamic simulations, and ensuring that the accuracy of the test results is not affected by external interference. Furthermore, the presence of the base helps to evenly distribute the weight of the top of the device (including the bracket, the motion mechanism and the head mold) and the dynamic load generated by the movement, reduce the pressure concentration on the ground, protect the ground from damage, and also improve the durability of the device.

[0012] Optionally, in an embodiment of the present application, a silicone anti-slip pad is provided on the side of the base away from the headform. In the implementation of the above solution, the silicone anti-slip pad is provided on the side of the base away from the headform. Since the silicone anti-slip pad can effectively increase the friction between the base and the contact surface, even when performing dynamic or high-intensity motion simulations, it can ensure that the device is stable and does not shift, avoiding test interruptions or safety accidents caused by sliding, thereby improving the stability and safety of the test. Furthermore, the rubber material is soft and has good wear resistance, which can protect the ground of the test area (such as laboratory desktops and floors) from scratches and damage, keeping the test environment clean and the original facilities intact. The silicone anti-slip pad has good adaptability and can effectively prevent slipping on different materials such as smooth tiles, wooden floors, and carpets, ensuring the wide application possibility of the device in different environments. The silicone itself has a certain elasticity and can absorb the tiny vibrations and noise generated during the motion simulation process, creating a quieter and more professional atmosphere for the test environment, while also protecting the precision components in the motion mechanism from vibration.

[0013] Optionally, in an embodiment of the present application, a fixing strap for fixing the wig is provided on the head mold. In the implementation process of the above scheme, by providing a fixing strap for fixing the wig on the head mold, it is possible to ensure that the wig is firmly attached to the head mold during the motion simulation process, and even when performing violent or complex head movements, the risk of the wig shifting or falling off can be reduced, thereby making the product testing in the wig-wearing state more accurate and effective. Furthermore, by fixing the wig with a fixing strap, it is possible to simulate the scenario of a real user wearing a wig, ensuring that the test results are close to the actual situation, which is particularly critical for evaluating the compatibility, comfort and safety of products that are in close contact with the head, such as sports helmets, headphones, glasses, etc., and the fixing strap design facilitates the quick installation and removal of the wig, making it easy to test different types of wigs on the same head mold or to perform multiple repeated tests, thereby improving the efficiency and flexibility of the test.

[0014] Optionally, in an embodiment of the present application, the surface of the head mold is provided with an anti-slip pattern. In the implementation process of the above solution, by providing an anti-slip pattern on the surface of the head mold, the friction between the head mold and the contact object is increased. In particular, when the head mold is used to display or test products such as hats, helmets, hair accessories, etc., it can effectively prevent these items from sliding on the head mold, maintain the stability of the display or test state, and ensure the accuracy of the test results. Furthermore, the anti-slip pattern helps to more accurately evaluate the fit and comfort of head-mounted products, because they can ensure that the product remains stationary in the correct position, making it easy to detect whether the product fits various head shapes and textures perfectly. Whether in a wet or dry environment, the anti-slip pattern can provide a stable grip, so that the head mold can maintain consistent performance when tested under different climatic conditions, increasing the wide applicability and reliability of the test.

[0015] Optionally, in an embodiment of the present application, the items to be tested include hats, headscarves, headwear, masks, face shields, or respirators. In implementing the above solution, by covering various types of headwear, from everyday accessories to protective gear, a comprehensive quality and performance evaluation of mainstream headgear on the market is ensured. Furthermore, the fit of these items on different headforms is evaluated using unified testing standards, including size, tightness, comfort, and compatibility with different head shapes, effectively improving test compatibility.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should also be noted that the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or device. In the absence of further restrictions, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] See Figure 1The diagram shows the structure of a motion simulation device provided by an embodiment of the present application. This embodiment of the present application provides a motion simulation device 110, comprising a head mannequin 111 and a motion mechanism 112. The head mannequin 111 is movably connected to the motion mechanism 112. Because the head mannequin 111 and the motion mechanism 112 are movably connected, the head mannequin can simulate human head movements through functions such as rotation and pivoting.

[0024] The head model 111 is used to wear the object to be tested. It is a model that simulates the shape of the human head. The specific shape and size of the head model can be set according to the specific scene. For example, the head circumference of the head model is set to 54.6 cm to represent the head size of an adult woman.

[0025] The motion mechanism 112 is used to simulate the motion scene of the object to be detected. Since the motion mechanism can simulate many kinds of motion, such as telescopic motion and / or rotational motion, etc., there are many kinds of motion scenes here, including but not limited to walking motion scenes, running motion scenes, etc.

[0026] In the implementation of the above solution, the head model of the motion simulation device is used to wear the test object, and the motion mechanism of the motion simulation device is used to simulate the motion of the test object, thus achieving the motion simulation function of the head movement. Furthermore, through the movable connection between the head model and the motion mechanism, the wearer's head dynamics in various motion states, such as walking, running, jumping, and shaking the head, can be simulated, ensuring that the test results are highly consistent with actual usage, thereby enhancing the degree of realistic simulation of the test.

[0027] See Figure 2 Schematic diagrams of the front view and side view of the motion simulation device provided by an embodiment of the present application are shown; as an optional implementation of the above-mentioned motion simulation device, the motion mechanism 112 includes: a telescopic shaft 112a; the telescopic shaft is movably connected to the head mold, the telescopic shaft is used to support the head mold and drive the head mold to perform telescopic movement, wherein the specific components of the telescopic shaft may vary according to different driving methods.

[0028] During the implementation of the above solution, the telescopic shaft is movably connected to the head model and drives the head model to perform telescopic movements, so that the head model can simulate the forward and backward, up and down, or left and right telescopic movements of the head in different motion states, such as the natural swing of the head when running or jumping, which improves the authenticity and accuracy of the test and helps to evaluate the fit, stability and comfort of the items to be tested under various dynamic conditions.

[0029] As an alternative embodiment of the aforementioned motion simulation device, if the telescopic shaft is electrically driven, the telescopic shaft 112a comprises: a motor, a reduction gear set, a threaded mechanism, bearings, a control circuit, and a telescopic rod. The threaded mechanism may include a telescopic rod and a nut. The motor is connected to the gears in the reduction gear set via the bearings, and the output shaft of the reduction gear set is connected to the telescopic rod. The telescopic rod passes through the housing and engages with the nut. The motor, which provides the driving force for the telescopic movement of the headform through the telescopic rod, can be a DC or AC motor. The reduction gear set is connected to the motor's output shaft, converting the motor's high-speed rotation into low-speed, high-torque rotational motion to meet the propulsion requirements of the telescopic rod. The telescopic rod in the threaded mechanism is connected to the motor via the gears in the reduction gear set. Rotation of the telescopic rod drives the nut along its axis. The bearings support the movement of the telescopic rod, reducing friction and ensuring smooth movement. The control circuit controls the start, pause, and stop of the telescopic movement. The telescopic rod supports the headform and, driven by the motor, allows the headform to perform short-distance telescopic movement. Of course, the telescopic shaft may also be driven by a hydraulic drive or a pneumatic drive, etc. The specific components of the telescopic shaft may vary according to the drive mode, and other modes will not be described here.

[0030] In the implementation of the above solution, a telescopic shaft structure including a telescopic rod and a motor is adopted, so that the motor drives the telescopic rod and the head model to perform telescopic movement. The motor drive provides precise power output and can accurately control the telescopic distance and speed of the head model according to preset programs or real-time instructions, thereby realizing the automation and refined management of the test scene, thereby improving the repeatability and accuracy of the test.

[0031] See Figure 3 A schematic diagram of an exploded view of a motion simulation device provided in an embodiment of the present application is shown. As an optional embodiment of the motion simulation device, the motion mechanism 112 further includes a rotating shaft 112b movably connected to the telescopic shaft, configured to drive the telescopic shaft and the headform to rotate. The rotating shaft is flexible and rotatable, for example, between -90° and 90°, and can also rotate within other rotation angle ranges. The specific rotation angle range should not be construed as limiting the embodiments of the present application.

[0032] In the implementation of the above solution, a rotating shaft is added to the original telescopic shaft, which is movably connected to the telescopic shaft and drives the telescopic shaft and the head mold to rotate, thereby effectively combining the telescopic and rotation functions. The motion mechanism can simulate the complex motion trajectory of the head in three-dimensional space, such as natural movements such as shaking the head and turning the head, greatly enhancing the authenticity and comprehensiveness of the motion scene.

[0033] As an optional embodiment of the motion simulation device, a fixing member 112c is provided on the rotating shaft 112b. The fixing member 112c is used to cooperate with the rotating shaft 112b to fix the rotation angle of the rotating shaft. The rotating shaft is flexibly rotatable. After rotating to a desired rotation angle, the fixing member can be used to fix the rotation angle of the rotating shaft. The fixing member can be a knob. After rotating to the desired rotation angle, the knob can be tightened inward to fix the rotation angle of the rotating shaft.

[0034] In implementing the above solution, the fixings allow the rotation axis to be set and locked at any preset angle, enabling precise angular control of the headform's rotational motion. This is crucial for testing that requires evaluating the performance of an item at a specific angle, such as simulating an athlete's gaze changes during competition or testing the comfort and stability of a head-mounted device at different tilt angles. Furthermore, the use of fixings ensures highly consistent testing conditions, allowing tests at the same angle to be accurately replicated, improving the comparability of experimental data and the reliability of test results.

[0035] As an optional embodiment of the motion simulation device, the motion simulation device 110 may further include a control module configured to receive simulation parameters and control the motion mechanism to perform corresponding motion based on the simulation parameters. The simulation parameter may be a rotation angle. The control module may receive the rotation angle and then control the rotation axis to perform motion based on the rotation angle (either directly to the rotation angle or in a swinging motion centered around the rotation angle). The simulation parameter may also be a telescopic frequency. The control module may receive the telescopic frequency and then control the telescopic axis to perform telescopic motion based on the telescopic frequency.

[0036] As an optional embodiment of the aforementioned motion simulation device, the motion simulation device 110 further includes a bracket 113; the motion mechanism is movably connected to the bracket, and the bracket is used to support the motion mechanism and the headform. The bracket can be flexibly rotated relative to the rotation axis, for example, between -90° and 90°. To better support the motion mechanism and the headform, the bracket can be made of metal and its thickness can be increased to enhance the stability of the entire motion simulation device.

[0037] In the implementation of the above solution, by adding a bracket as a supporting base to the motion simulation device, it can be ensured that the entire motion simulation device remains stable during complex motion simulation, preventing the device from tipping over or shifting, thereby ensuring the safety of the test environment and improving the reliability and accuracy of the test results.

[0038] As an optional embodiment of the aforementioned motion simulation device, the side of the bracket 113 can be provided with a scale ranging from -90° to 90°, and the telescopic shaft can be provided with a pointer 112d, which indicates the current rotation angle on the scale. To more easily read the current rotation angle, the bracket can also be shaped as a semicircle. As the telescopic shaft rotates, the pointer on the shaft is compared with the scale on the semicircle to read the rotation angle indicated by the pointer. This allows the motion simulation device to measure the rotation angle of the headform driven by the telescopic shaft, providing consistent and repeatable rotation angle data for scientific and quantitative stability testing.

[0039] In implementing the above solution, by providing a scale on the side of the bracket and equipping the telescopic shaft with a pointer to indicate the current rotation angle, the pointer and scale work together to intuitively and quickly read the specific rotation angle of the current rotating shaft, without the need for additional electronic instruments or complex calculations, thereby improving the convenience and efficiency of test operations. Furthermore, the precise positioning capability of the scale and pointer ensures that the same angle conditions can be accurately reproduced in each test. This is particularly important when multiple comparative tests at specific angles are required, helping to improve the accuracy of test data and the repeatability of test results.

[0040] As an optional embodiment of the aforementioned motion simulation device, motion simulation device 110 further includes a base 114; base 114 is fixedly connected to bracket 113 and is used to support bracket 113, motion mechanism 112, and headform 111. To more stably support the entire motion simulation device, the base can be made entirely of metal to increase weight, thereby enhancing the stability of the motion simulation device during stability testing.

[0041] In implementing the above solution, a base is added to the motion simulation device, fixedly connected to the bracket to jointly support the bracket, motion mechanism, and headform. The base serves as the foundation of the device, providing a stable support platform for the entire motion simulation device. This significantly enhances the device's stability and vibration resistance during various dynamic simulations, ensuring that the accuracy of test results is unaffected by external interference. Furthermore, the presence of the base helps evenly distribute the weight of the top of the device (including the bracket, motion mechanism, and headform) and the dynamic loads generated by the movement, reducing pressure concentration on the ground, protecting the ground from damage, and improving the durability of the device.

[0042] As an optional embodiment of the aforementioned motion simulation device, a silicone anti-slip pad is provided on the side of the base facing away from the headform. In other words, the side of the base that contacts the ground or tabletop can also be provided with a silicone anti-slip pad to increase friction between the base and the ground or tabletop, effectively reducing the probability of the entire motion simulation device tipping over in strong airflow.

[0043] In the implementation of the above solution, a silicone anti-slip pad is provided on the side of the base away from the head mold. Since the silicone anti-slip pad can effectively increase the friction between the base and the contact surface, it can ensure that the device is stable and does not shift even when performing dynamic or high-intensity motion simulations, avoiding test interruptions or safety accidents caused by sliding, thereby improving the stability and safety of the test. Furthermore, the rubber material is soft and has good wear resistance, which can protect the ground of the test area (such as laboratory desktops and floors) from scratches and damage, keeping the test environment clean and the original facilities intact. The silicone anti-slip pad has good adaptability and can effectively prevent slipping on different materials such as smooth tiles, wooden floors, and carpets, ensuring the wide application possibility of the device in different environments. The silicone itself has a certain elasticity and can absorb the tiny vibrations and noise generated during the motion simulation process, creating a quieter and more professional atmosphere for the test environment, while also protecting the precision components in the motion mechanism from vibration.

[0044] As an optional embodiment of the aforementioned motion simulation device, the head mannequin 111 is provided with a securing strap 111a for securing different types of wigs. Specifically, the securing strap 111a can be used to attach wigs and can be positioned along the entire hairline of the head mannequin's surface, thereby simulating wearers of the object to be inspected with different hairstyles. The securing strap 111a can be a mesh webbing with elastic force, the elasticity of which can be adjusted according to the specific situation. The mesh webbing can interact with the reverse clip on the wig to securely secure the wig to the securing strap.

[0045] During the implementation of the above solution, by providing a fixing strap for fixing the wig on the headform, it is possible to ensure that the wig is firmly attached to the headform during the motion simulation process. Even during intense or complex head movements, the risk of the wig shifting or falling off can be reduced, thereby making product testing in the wig-wearing state more accurate and effective. Furthermore, by fixing the wig with a fixing strap, it is possible to simulate the scene of a real user wearing a wig, ensuring that the test results are close to the actual situation. This is particularly critical for evaluating the compatibility, comfort and safety of products that come into close contact with the head, such as sports helmets, headphones, and glasses. The fixing strap design facilitates the quick installation and removal of the wig, making it easy to test different types of wigs on the same headform or to conduct multiple repeated tests, thereby improving testing efficiency and flexibility.

[0046] As an optional embodiment of the above-mentioned motion simulation device, the surface of the head mold can be provided with an anti-slip pattern, and the material of the head mold surface can be silicone, thereby effectively increasing the friction between the head mold and the wig, and preventing the wig from falling during the stability test.

[0047] In implementing the above solution, by providing an anti-slip pattern on the surface of the headform, the friction between the headform and the contact object is increased. In particular, when the headform is used to display or test products such as hats, helmets, and hair accessories, it can effectively prevent these items from sliding on the headform, maintaining the stability of the display or testing state and ensuring the accuracy of the test results. Furthermore, the anti-slip pattern helps to more accurately evaluate the fit and comfort of head-worn products because it can ensure that the product remains in the correct position, facilitating the detection of whether the product perfectly fits various head shapes and textures. Whether in wet or dry environments, the anti-slip pattern can provide stable grip, allowing the headform to maintain consistent performance when tested in different climate conditions, increasing the wide applicability and reliability of the test.

[0048] As an optional implementation of the above-mentioned motion simulation device, the items to be tested include: hats, headscarves, headwear, masks, face shields, respirators, glasses, helmets, and head-mounted headphones, etc. Therefore, the items to be tested are any items that can be worn on a head model, and the types and quantities of specific items should not be understood as limitations of the embodiments of the present application. In the implementation of the above-mentioned scheme, by covering various types of items worn on the head, from daily accessories to protective equipment, a comprehensive quality and performance evaluation of mainstream head equipment on the market is ensured, and the adaptability of these items on different head models is evaluated through unified test standards, including size, tightness, comfort, and tolerance to different head shapes, thereby effectively improving the compatibility of the test.

[0049] Optionally, during implementation, the motion simulation device can be used to perform quality inspections on items worn on the head, such as hats, headscarves, headwear, masks, face shields, respirators, glasses, helmets, and the like. For example, a designer may rely on intuition and experience to observe fashionable headwear in a static environment. After inspecting the appearance and material properties of the headwear, an engineer can use the motion simulation device to perform a quality inspection and evaluation on the headwear. Specifically, the motion scene of the item is simulated, and a blower is used to blow out an adjustable airflow, for example, from small to large, until the item is blown off by the airflow. The stability of the item is then determined based on the wind speed at which it is blown off, ultimately evaluating the stability of the headwear item (e.g., a sports cap) during high-intensity activities such as running and jumping.

[0050] Optionally, the above-mentioned motion simulation device can also be used in the application scenario of commodity inspection and identification. For example, if the above-mentioned item to be inspected is a commodity, which can be a hat of the same or different models, etc., the above-mentioned motion simulation device can be used to simulate the movement scene of the hat, and a fan can be used to blow an airflow adjusted from small to large to the item until the item is blown off by the airflow. Then, the stability of the item is determined based on the wind speed when it is blown off by the airflow, so as to check whether these same or different models of goods are produced by the same company, and documents such as inspection reports can also be issued. For another example, if the above-mentioned item to be inspected is a hat, in addition to manually ensuring that the appearance characteristics and material of the hat are consistent with the authentic one, the above-mentioned motion simulation device can be used to detect the stability of the hat (see the previous example for the specific process), so as to identify whether the stability of the hat is consistent with that of the authentic one.
