Description

Technical Field

[0001] The utility model relates to the field of automobile passive safety, in particular to a protective gear for adjusting the spinal stiffness of a BioRID dummy. Background Art

[0002] With the rapid development of autonomous driving technology, active safety technologies such as Automatic Emergency Braking (AEB) have become crucial for reducing traffic accidents and protecting occupants. Using advanced sensors and algorithms, AEB systems can quickly identify and respond to potential collision risks, automatically slowing down or applying the brakes, significantly reducing the likelihood of a collision. Even in unavoidable accidents, AEB can mitigate the impact on occupants by reducing vehicle speed, thereby minimizing injuries.

[0003] During emergency braking, the occupants' bodies tend to tilt forward due to inertia, causing them to be out of position when a collision occurs. This significantly increases the risk of whiplash injuries to the occupants' necks, especially in rear-end collisions. To further investigate the dynamic response and injuries to occupants during emergency braking and collisions, trolley whiplash tests have become an important tool in vehicle occupant protection research. As the most widely used physical dummy model in current trolley whiplash tests, the BioRID dummy model can realistically simulate the dynamic response and injuries of real people in rear-end collision conditions, providing valuable reference data for the design and evaluation of vehicle passive safety systems.

[0004] However, in traditional whiplash tests, the BioRID dummy's spine design does not fully simulate the stiffness and dynamic response characteristics of a real human body. In particular, when there is no additional support, the dummy may experience excessive displacement during braking due to insufficient spine stiffness. This excessive displacement not only differs from the dynamic response of a real human under the same operating conditions, but can also affect the accuracy of test results, misleading the design and evaluation of vehicle passive safety systems. Utility Model Content

[0005] The utility model aims to provide a protective gear for adjusting the spinal stiffness of a BioRID dummy, so as to solve the problem that the dummy may have excessive displacement due to insufficient spinal stiffness in traditional whiplash tests.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A protective gear for adjusting the spinal stiffness of a BioRID dummy, comprising a front fixing plate, a rear fixing plate, a shoulder strap assembly, and a waist belt assembly. The front fixing plate can be used to be installed on the front chest area of ​​the dummy, and the rear fixing plate can be used to be installed on the back area of ​​the dummy; one end of the shoulder strap assembly is detachably mounted on the front fixing plate, and the other end is fixed to the rear fixing plate, and the shoulder strap assembly is configured as a length-adjustable structure; both ends of the waist belt assembly are detachably mounted on the front fixing plate and the rear fixing plate, respectively, and the waist belt assembly is configured as a length-adjustable structure so that the shoulder strap assembly and the waist belt assembly can adjust their lengths according to the size of the thoracolumbar vertebrae of the dummy, thereby fixing and supporting the dummy's spine.

[0008] Based on the above-mentioned technical means, the protective gear of the present invention can closely fit the dimensions of the thoracic and lumbar spine of the BioRID dummy by precisely adjusting the length of the shoulder strap assembly and the waist belt assembly, thereby effectively supporting and fixing the spine of the BioRID dummy. This enhances the spinal stiffness of the dummy during braking tests, thereby simulating the spinal response of a real human body during braking. This makes the displacement of the dummy's various parts (such as the displacement of the head, chest, pelvis, etc.) more similar to the displacement of volunteers with the same physical signs under similar test conditions, greatly improving the accuracy and reliability of the simulation test and providing test data that is closer to real conditions for vehicle safety performance evaluation.

[0009] Furthermore, the shoulder strap assembly includes a shoulder strap body, a first connecting member and a second connecting member, the first connecting member is fixed to the front fixing plate, and the second connecting member is fixed to the rear fixing plate; one end of the shoulder strap body is detachably mounted on the front fixing plate through the first connecting member, and the other end of the shoulder strap body is fixed to the rear fixing plate through the second connecting member.

[0010] The above-mentioned technical means, through the design of the shoulder strap assembly, especially the shoulder strap body having one end detachably mounted on the front fixing plate via a first connector and the other end fixed to the rear fixing plate via a second connector, provide the BioRID dummy with continuous support from the chest to the back, significantly enhancing the stiffness of the dummy's spine, effectively reducing the amount of dummy displacement during braking or collision tests, and improving the accuracy and reliability of the test results.

[0011] The adjustable shoulder strap length allows the harness to adapt to BioRID dummies of varying sizes and shapes, ensuring optimal fit and comfort. Adjusting the shoulder strap length allows precise control of the support applied to the dummy's spine, resulting in more consistent data across various test conditions.

[0012] Furthermore, a first hook surface and a first hairy surface are formed on one side of the shoulder strap body, and the first hook surface is located at one end of the shoulder strap body; the first hairy surface is arranged along the length direction of the shoulder strap body; one end of the shoulder strap body can pass through the first connecting piece and extend to the other end, so that the first hook surface can be adhered to the first hairy surface, thereby adjusting the length of the shoulder strap assembly.

[0013] The aforementioned technical approach creates a simple and efficient length adjustment mechanism using the first hook and first loop surface on the shoulder strap body. Users simply thread one end of the shoulder strap body through the first connector and then attach the first hook to the first loop surface in the appropriate position to easily adjust the shoulder strap length. This also allows the shoulder strap assembly to accommodate BioRID dummies of varying shapes and sizes, meeting the requirements of diverse testing conditions.

[0014] Furthermore, the first connecting member includes a first hanging ring and a first hanging strap, the first hanging strap is fixed on the front fixing plate, and the first hanging ring is installed on the first hanging ring so that the first hanging ring is installed on the front fixing plate; one end of the shoulder strap body can pass through the first hanging ring and extend to the other end to adjust the length of the shoulder strap assembly.

[0015] According to the above technical means, the combination of the first hanging ring and the first hanging strap allows the shoulder strap body to be easily passed through the first hanging ring for adjustment. The user simply needs to pass the shoulder strap body through the first hanging ring and adjust it to the desired length to quickly secure and adjust the shoulder strap assembly, greatly simplifying the adjustment process and improving the efficiency of test preparation.

[0016] Furthermore, the second connecting member includes a second hanging ring and a second hanging strap, the second hanging strap is fixed on the rear fixing plate, and the second hanging ring is installed on the second hanging ring so that the second hanging ring is installed on the rear fixing plate; the other end of the shoulder strap body is installed on the second hanging ring so that the shoulder strap body is fixed on the rear fixing plate.

[0017] The second connector, through the combination of the second loop and the second strap, provides a secure anchor point for the shoulder strap. The other end of the shoulder strap is attached to the second loop, ensuring a secure connection to the rear mounting plate and maintaining stable support even under dynamic testing conditions.

[0018] Furthermore, the waist belt assembly includes a waist belt body, a third connecting member and a snap-on assembly, one end of the waist belt assembly is connected to the snap-on assembly, and the snap-on assembly can be snapped onto the front fixing plate so that one end of the waist belt assembly can be detachably mounted on the front fixing plate; the third connecting member is fixed to the rear fixing plate, and the other end of the waist belt assembly is connected to the third connecting member so as to be mounted on the rear fixing plate.

[0019] According to the above technical means, the waist belt assembly is detachably connected to the front fixing plate via a snap-on assembly. This design makes the installation and removal of the waist belt assembly very simple and quick. The user only needs to snap the snap-on assembly onto the front fixing plate to complete the installation of the waist belt assembly; similarly, for removal, it is only necessary to remove the snap-on assembly from the front fixing plate, without the need for complicated operations or additional tools. The snap-on structure between the snap-on assembly and the front fixing plate ensures the stability of the waist belt assembly during the test, effectively preventing the waist belt from loosening or falling off during dynamic tests, thereby ensuring stable support for the BioRID dummy's waist. At the same time, the design of the waist belt assembly allows it to easily adapt to BioRID dummies of different body shapes and sizes. By adjusting the length of the waist belt body and combining it with the flexibility of the snap-on assembly, it can be ensured that the waist belt provides appropriate support under different test conditions.

[0020] Furthermore, two second hook surfaces and a second hairy surface are formed on one side of the belt body, and the two second hook surfaces are respectively located at the two ends of the belt body, the second hairy surface is arranged in the length direction of the belt body, and the second hairy surface is located between the two second hook surfaces; the two ends of the belt body can respectively pass through the third connecting piece and the snap-on assembly to extend toward the middle section of the belt body, so that the two second hook surfaces can be attached to the second hairy surface, thereby adjusting the length of the belt body.

[0021] The two second hook surfaces and second fleece surface provided on the belt body provide an intuitive and efficient length adjustment mechanism. The user can easily adjust the belt's length by threading each end of the belt body through the third connector and the snap-on assembly, then attaching the second hook surfaces to the appropriate locations on the second fleece surface. This eliminates the need for additional adjusters or tools, significantly simplifying the operation process.

[0022] Furthermore, the third connecting member includes a third hanging ring and a third hanging strap, the third hanging strap is fixed on the rear fixing plate, and the third hanging ring is installed on the third hanging strap so that the third hanging ring is installed on the rear fixing plate; the other end of the belt body can pass through the third hanging ring and extend to the middle section to adjust the length of the belt body.

[0023] Based on the aforementioned technical approach, the third connector, through the combination of a third loop and a third strap, provides a flexible adjustment point for the belt itself. The user can thread the other end of the belt through the third loop and adjust the belt length as needed for optimal securement. Because the belt can be freely adjusted through the third loop, it can easily accommodate BioRID dummies of varying shapes and sizes, making the protective gear more versatile and meeting the needs of diverse testing conditions.

[0024] Furthermore, the clip assembly includes a fourth hanging ring, a first clip and a second clip, the fourth hanging ring is fixed to the first clip, and one end of the belt body can pass through the fourth hanging ring and extend to the middle section to adjust the length of the belt body; the second clip is installed on the front fixing plate, and the first clip can be engaged or disengaged with the second clip so that one end of the belt assembly can be detachably mounted on the front fixing plate.

[0025] The aforementioned technology allows the clip assembly to provide a convenient adjustment point for the belt body via the fourth loop. Users can thread one end of the belt through the fourth loop and adjust the belt length to suit the BioRID dummy's size or test requirements, ensuring optimal securement. This not only increases belt flexibility but also enhances the adaptability of the protective gear.

[0026] The clamping structure between the first and second clamping parts ensures the stability of the waist belt assembly during testing, effectively preventing the belt from loosening or falling off during dynamic testing. This ensures stable support for the BioRID dummy's waist and improves the accuracy of test results. Furthermore, the design of the clamping assembly makes installation and removal of the waist belt assembly simple and quick. The user simply engages or disengages the first and second clamping parts to complete installation or removal of the waist belt.

[0027] Furthermore, the first clamping member is a buckle, and the second clamping member is a clamping hole.

[0028] The combination of the buckle and the eye provides a simple and effective connection method. The user simply aligns the buckle with the eye and gently presses to quickly connect the waist belt assembly to the front fixing plate. Furthermore, the tight fit between the buckle and the eye ensures a secure connection, preventing the waist belt assembly from accidentally falling off during testing.

[0029] Beneficial effects achieved by this utility model:

[0030] The protective gear of the present invention can closely fit the dimensions of the thoracic and lumbar vertebrae of the BioRID dummy by precisely adjusting the lengths of the shoulder and waist belt assemblies, thereby effectively supporting and fixing the spine of the BioRID dummy. This enhances the spinal stiffness of the dummy during braking tests, thereby simulating the spinal response of a real human body during braking. This makes the displacement of the dummy's various parts (such as the displacement of the head, chest, pelvis, etc.) more similar to that of volunteers with the same physical signs under similar test conditions, greatly improving the accuracy and reliability of the simulation test and providing test data that is closer to real conditions for vehicle safety performance evaluation.

[0063] The first hook surface 311 and first fleece surface 312 on the shoulder strap body 31 form a simple and efficient length adjustment mechanism. The user simply passes one end of the shoulder strap body 31 through the first connector 32 and then adheres the first hook surface 311 to the fleece surface 312 in the appropriate position to easily adjust the shoulder strap length. This also allows the shoulder strap assembly 3 to accommodate BioRID dummies of varying shapes and sizes, meeting the requirements of diverse testing conditions.

[0071] The waist belt assembly 4 is detachably connected to the front fixing plate 1 via a snap-on assembly 43. This design makes installation and removal of the waist belt assembly 4 simple and quick. To install the waist belt assembly 4, the user simply snaps the snap-on assembly 43 onto the front fixing plate 1. Similarly, to remove the waist belt assembly 4, the user simply removes the snap-on assembly 43 from the front fixing plate 1, eliminating the need for complex manipulation or additional tools. The snap-on connection between the snap-on assembly 43 and the front fixing plate 1 ensures the stability of the waist belt assembly 4 during testing, effectively preventing the belt from loosening or falling off during dynamic testing, thereby ensuring stable support for the BioRID dummy's waist. Furthermore, the design of the waist belt assembly 4 allows it to easily adapt to BioRID dummies of varying body shapes and sizes. By adjusting the length of the waist belt body 41, combined with the flexibility of the snap-on assembly 43, the belt can provide appropriate support under different test conditions.

[0072] like Figure 3 As shown, two second hook surfaces 411 and a second hairy surface 412 are formed on one side of the belt body 41. The two second hook surfaces 411 are respectively located at the two ends of the belt body 41. The second hairy surface 412 is arranged in the length direction of the belt body 41, and the second hairy surface 412 is located between the two second hook surfaces 411; the two ends of the belt body 41 can respectively pass through the third connecting piece 42 and the snap-on assembly 43 to extend toward the middle section of the belt body 41, so that the two second hook surfaces 411 can be adhered to the second hairy surface 412, thereby adjusting the length of the belt body 41.

[0073] The two second hook surfaces 411 and second fleece surface 412 on the belt body 41 provide an intuitive and efficient length adjustment mechanism for the belt body 41. The user can easily adjust the belt's length by threading the ends of the belt body 41 through the third connector 42 and the snap assembly 43, respectively, and then attaching the second hook surfaces 411 to the appropriate positions on the second fleece surface 412.

[0075] The third connecting member 42, through the combination of a third loop 421 and a third strap 422, provides a flexible adjustment point for the waist belt 41. The user can thread the other end of the waist belt through the third loop 421 and adjust the length of the belt as needed for optimal securement. Because the waist belt 41 can be freely adjusted through the third loop 421, it can easily accommodate BioRID dummies of varying shapes and sizes, making the protective gear more versatile and meeting the needs of diverse testing conditions.

[0076] like Figure 1-Figure 2 As shown, the clip assembly 43 includes a fourth hanging ring 431, a first clip 432 and a second clip 433. The fourth hanging ring 431 is fixed to the first clip 432.

The second clip 433 is installed on the front fixing plate 1. The first clip 432 can be clipped or released with the second clip 433 so that one end of the belt assembly 4 can be detachably installed on the front fixing plate 1.

[0077] The clip assembly 43 provides a convenient adjustment point for the waist belt 41 via the fourth loop 431. The user can thread one end of the waist belt 41 through the fourth loop 431 and then adjust the length of the waist belt 41 based on the BioRID dummy's body shape or test requirements to ensure optimal securement. This not only increases the flexibility of the belt but also enhances the adaptability of the protective gear.

[0078] The fastening structure between the first and second fasteners 432, 433 ensures the stability of the waist belt assembly 4 during testing, effectively preventing the waist belt body 41 from loosening or falling off during dynamic testing. This ensures stable support for the BioRID dummy's waist and improves the accuracy of test results. Furthermore, the design of the fastener 43 makes installation and removal of the waist belt assembly 4 simple and quick. The user simply engages or disengages the first and second fasteners 432, 433 to complete installation or removal.

[0079] like Figure 1-Figure 2 As shown, the first clamping member 432 is a buckle, and the second clamping member 433 is a clamping hole.

[0080] The combination of the buckle and the hole provides a simple and effective connection method.
