[0032] Reference below Figure 1 - Figure 4 The present invention describes a high-speed camera bracket 100 for a vehicle 1000 crash test. The high-speed camera bracket 100 is used to secure a camera 200 to the lower foot of a seat in a driver's cabin 1001 or a passenger cabin 1002 during a crash test of the vehicle 1000 to observe the foot movements of a dummy.
[0033] like Figure 1 - Figure 3 As shown, a high-speed camera bracket 100 according to some embodiments of the first aspect of the present invention includes a guide rod 10, a bushing 20, and a mounting platform 30 for mounting a camera 200. Both ends of the guide rod 10 are mounted on a vehicle 1000 to be tested. The bushing 20 is externally connected to the guide rod 10 and is configured to rotate about and slide along the guide rod 10. The mounting platform 30 is connected to the bushing 20.
[0034] The guide rod 10 serves as the main axis of the entire high-speed camera bracket 100 and is used to fix and guide other components. The two ends of the guide rod 10 can be fixed on the designated position of the vehicle 1000. Figure 4 In the illustrated embodiment, the guide rod 10 is installed at the lower end of the seat foot of the cockpit or the co-pilot cabin 1002, and both ends of the guide rod 10 are respectively connected to the seat frame.
[0035] The bushing 20 is connected to the guide rod 10 and is configured to be rotatable around the guide rod 10 and slidable along the guide rod 10 .
[0036] The bushing 20 enables the mounting platform 30 to be adjusted at multiple angles on the guide rod 10. Specifically, the bushing 20 is connected to the guide rod 10 in an outer sleeve, and the bushing 20 can rotate around the guide rod 10 and can also slide along the axial direction of the guide rod 10.
[0037] Therefore, the design of the bushing 20 allows it to rotate and slide freely on the guide rod 10, thereby driving the high-speed camera 200 to adjust the shooting angle and position.
[0038] For example, during a test, operators can adjust the position and rotation angle of the high-speed camera bracket 100 in real time based on the different stages of the collision simulation or the specific changes in the dummy's foot's motion. For example, in the initial stages of a collision, operators can adjust the camera 200 to a lower position to more clearly capture the initial contact and initial reaction of the dummy's foot with the internal structure of the vehicle 1000. During the critical stages of the collision, they can raise the camera 200 or rotate it to a specific angle to more comprehensively record the motion trajectory of the dummy's foot under the action of inertial forces, posture changes, and possible collision points.
[0039] This arrangement allows the high-speed camera 200 to be flexibly adjusted to the optimal shooting angle and position, thereby improving the flexibility and convenience of the high-speed camera bracket 100. Furthermore, by using the bushing 20 mounted on the guide rod 10, the bushing 20 can rotate and slide around the guide rod 10. During this rotation and sliding process, the bushing 20 takes up little space, thus achieving a wide adjustment range with a small space.
[0040] In addition, by adjusting the rotation angle and sliding position of the bushing 20 on the guide rod 10 , the high-speed camera bracket 100 can be adapted to a variety of different models of vehicles 1000 and different testing requirements, thereby improving the flexibility of the high-speed camera bracket 100 .
[0041] In some optional embodiments, the guide rod 10 is not limited to a “solid structure”, for example, it can also be a “hollow structure”.
[0042] In some embodiments, as Figure 1 - Figure 3As shown, the bushing 20 can be directly put on the guide rod 10. In this case, the inner diameter of the bushing 20 is slightly larger than the outer diameter of the guide rod 10, but the gap between the two is very small, so that under normal operation, the bushing 20 will not easily slide due to a slight external force. This fitting method allows a certain degree of fine-tuning, but ensures that the bushing 20 can still maintain a stable position when subjected to a sufficiently large external force. Alternatively, an interference fit is adopted between the bushing 20 and the guide rod 10. The inner diameter of the bushing 20 is slightly smaller than the outer diameter of the guide rod 10. At this time, a large prestress will be generated between the bushing 20 and the guide rod 10, thereby providing a strong friction force through the elastic deformation of the material itself, ensuring that the bushing 20 will not fall off or move on its own.
[0043] In some optional embodiments, an anti-skid layer is provided in the bushing 20. During the test, the anti-skid layer can increase the stability of the bushing 20 on the guide rod 10, thereby increasing the stability of the bushing 20 and ensuring the accuracy of the test.
[0044] like Figure 1 - Figure 3 As shown, the mounting platform 30 is used to fix the high-speed camera 200. The mounting platform 30 is connected to the bushing 20, and the adjustment capability of the bushing 20 is used to adjust the angle and position of the camera 200.
[0045] For example, by rotating the bushing 20, the mounting platform 30 and the high-speed camera 200 mounted thereon can be driven to rotate circumferentially about the axis of the guide rod 10, thereby changing the shooting angle of the high-speed camera 200. By sliding the bushing 20, the high-speed camera 200 and its mounting platform 30 can be smoothly moved along the length of the guide rod 10. Throughout the adjustment process, the mounting platform 30 and the bushing 20 are securely fixed, which not only improves the smoothness and accuracy of adjustment, provides convenience for the operator, but also ensures the stability of the high-speed camera 200.
[0046] like Figure 1 - Figure 2 As shown, the high-speed camera bracket 100 for the collision test of the vehicle 1000 according to some embodiments of the present invention further includes: a movable fastener 40, the fastener 40 is connected to the bushing 20, or connected between the bushing 20 and the guide rod 10 to fix the adjusted bushing 20 on the guide rod 10.
[0047] The fastener 40 serves as a connection and locking mechanism, and is used to firmly fix the bushing 20 adjusted to an ideal position and angle on the guide rod 10 to prevent position displacement caused by vibration or impact during the test.
[0048] In some optional embodiments, a movable fastener 40 is connected to the bushing 20. The fastener 40 can be a snap-fit device that can achieve tensioning. When the position of the bushing 20 needs to be adjusted, the snap-fit device is released to change it from a locked state to a released state, thereby allowing the bushing 20 to move freely on the guide rod 10. After the snap-fit device is released, the operator can slide or rotate the bushing 20 along the guide rod 10 until it reaches a preset ideal position. When the bushing 20 is adjusted to the preset position, the operator will operate the snap-fit device again to change it from the released state back to the locked state. This step ensures that the bushing 20 is firmly fixed on the guide rod 10 and prevents positional displacement due to factors such as vibration and impact.
[0049] In some optional embodiments, the fastener 40 is connected between the bushing 20 and the guide rod 10 to fix the adjusted bushing 20 on the guide rod 10. For example, the bushing 20 is provided with a threaded hole, and the fastener 40 is provided with a threaded structure. When the bushing 20 needs to be fixed, the operator first passes the fastener 40 through the threaded hole on the bushing 20, and then rotates the fastener 40 so that its thread is tightly engaged with the threaded hole of the bushing 20. As the fastener 40 rotates, one end of the fastener 40 gradually penetrates the threaded hole and abuts against the surface of the guide rod 10. During this process, the axial force generated by the fastener 40 presses the bushing 20 firmly against the guide rod 10, thereby achieving the fixation of the bushing 20. Due to the characteristics of the threaded connection, this fixing method is not only stable and reliable, but also has a certain self-locking property, and can resist the vibration and impact generated during the test to a certain extent. Optionally, the fastener 40 can be a bolt, screw, etc. with an external thread.
[0050] According to some embodiments of the high-speed camera bracket 100 for a vehicle 1000 collision test, a slit 21 is provided on the bushing 20 , and the slit 21 is provided along the axial direction of the guide rod 10 .
[0051] The design of the slit 21 thus allows a certain degree of adjustability of the bushing 20 on the guide rod 10. Since there is a certain amount of frictional resistance between the bushing 20 and the guide rod 10, the design of the slit 21 reduces this frictional resistance to a certain extent. The operator can change the shooting angle of the camera 200 by rotating the bushing 20 without worrying about rotation difficulties caused by excessive frictional resistance.
[0052] In some optional embodiments, the bushing 20 is annular with an opening, that is, the bushing 20 is a non-closed ring, wherein "ring" is understood in a broad sense, that is, not limited to "circular ring", for example, it can also be a "polygonal ring" and so on.
[0053] Combine Figure 2The bushing 20 is further provided with a connecting portion 22, and there are at least two connecting portions 22, which are arranged on both sides of the slit 21 in the circumferential direction. A fastener 40 is connected to the two connecting portions 22, and the length of the fastener 40 between the two connecting portions 22 is adjustable to adjust the tightness of the bushing 20.
[0054] The layout of the connecting portion 22 ensures that the fastener 40 can evenly apply external force to the bushing 20, avoiding damage or deformation caused by force concentration. At the same time, the provision of at least two connecting portions 22 also provides sufficient stability and adjustment space.
[0055] Optionally, combined Figure 2 The connecting portion 22 is provided with a connecting hole 221. The connecting hole 221 provides a passage for the fastener 40 to pass through. After the fastener 40 passes through the connecting holes 221 on the two connecting portions 22, it is tightened by rotating or other means, so that the bushing 20 can be firmly fixed on the guide rod 10.
[0056] For example, as the two connecting portions 22 gradually approach each other, the distance between them decreases, causing the width of the slit 21 to also decrease accordingly. The reduction in slit 21 increases the contact area between the bushing 20 and the guide rod 10, and the friction force increases accordingly. Therefore, when the distance between the slit 21 decreases, the friction force between the bushing 20 and the guide rod 10 increases. This increased friction force helps to resist the influence of external forces on the position of the bushing 20, allowing the bushing 20 to be more firmly held in a specific position on the guide rod 10.
[0057] As the two connecting portions 22 move away from each other, the width of the slit 21 increases accordingly. However, as the width of the slit 21 increases, the contact pressure between the bushing 20 and the guide rod 10 decreases, and the friction also decreases accordingly. Therefore, the increased width of the slit 21 provides the bushing 20 with greater freedom. In scenarios where the rotation angle or position of the bushing 20 needs to be adjusted, the operator can more easily change the direction or position of the bushing 20 using external tools or manually. Due to the presence of the slit 21, the bushing 20 can flexibly adjust its rotation angle and position, thereby improving the flexibility of the high-speed camera bracket 100.
[0058] Optionally, the fastener 40 includes a bolt, a screw, and a nut. When the bushing 20 needs to be fixed to a certain position of the guide rod 10, a bolt can be passed through the connection hole 221 on the guide rod 10 and tightened from the other side with a nut to ensure that the bushing 20 is firmly fixed to the guide rod 10 and ensure the stability of the bushing 20 during the test.
[0059] According to the utility model Figure 1 - Figure 3The high-speed camera bracket 100 of the illustrated embodiment further includes: a telescopic rod 50, which is connected to the end of the guide rod 10. At least one end of the guide rod 10 is connected to the telescopic rod 50, and the telescopic rod 50 is movable along the axial direction of the guide rod 10 to adjust the total length of the high-speed camera bracket 100.
[0060] In the above technical solution, one end of the telescopic rod 50 is connected to the end of the guide rod 10. This connection can be achieved by a thread, a buckle or other mechanical fasteners 40 to ensure the firmness of the connection.
[0061] The telescopic rod 50 can slide freely in the axial direction of the guide rod 10 , which means that the operator can adjust the extension or retraction degree of the telescopic rod 50 as needed, thereby changing the overall length of the entire high-speed camera bracket 100 .
[0062] First, by adjusting the length of the telescopic rod 50 , the adjustable range of the high-speed camera 200 in the axial direction can be increased, ensuring that the required data is captured from the optimal angle.
[0063] Secondly, adjusting the overall length of the high-speed camera bracket 100 can achieve a positioning and locking function. After the telescopic rod 50 is extended, the overall length of the high-speed camera bracket 100 increases, allowing it to be supported in the predetermined position, ensuring that the high-speed camera bracket 100 will not loosen or fall off due to external forces during the test.
[0064] In addition, the presence of the telescopic rod 50 allows the same high-speed camera bracket 100 to be applied to vehicles 1000 of different sizes, thereby improving the versatility of the device.
[0065] In some optional embodiments, the guide rod 10 is provided with an internal thread; the telescopic rod 50 is provided with an external thread adapted to the internal thread, and the guide rod 10 and the telescopic rod 50 are connected by threaded cooperation.
[0066] During rotation, the external thread rises or falls along the internal thread spiral, thereby extending or retracting the telescopic rod 50 .
[0067] This threaded connection not only provides a reliable fixing effect, but also allows the operator to achieve fine adjustment of the length by rotating the telescopic rod 50.
[0068] In addition, the threaded connection can also provide good mechanical engagement, so that in the adjusted state, the telescopic rod 50 can remain stable and will not be displaced due to the impact force generated by the collision of the vehicle 1000.
[0069] In some optional embodiments, such as Figure 1 - Figure 3 As shown, the telescopic rod 50 further includes a support plate 60 rotatably connected to the end of the telescopic rod 50 .
[0070] The primary function of the support plate 60 is to increase the contact area between the end of the telescopic rod 50 and the vehicle 1000. During a collision test of vehicle 1000, the high-speed camera bracket 100 needs to be securely fixed to the vehicle 1000 to capture the moment of impact. The introduction of the support plate 60 effectively disperses the pressure at the end of the telescopic rod 50, making the pressure distribution more uniform and preventing damage or instability caused by excessive localized stress.
[0071] By increasing the contact area, the bracket is made more stable on the vehicle 1000 and is less likely to shake or move, thereby ensuring the clarity and accuracy of the captured image.
[0072] The support plate 60 is mounted at the end of the telescopic rod 50 via a pivoting connection, allowing it to adjust its position as the interior surface of the vehicle 1000 changes, ensuring optimal contact with the surface. Whether the contact surface is flat, slightly tilted, or has complex curves, the pivoting support plate 60 can adapt. This design allows the high-speed camera bracket 100 to be used with a wider variety of vehicles 1000 and test scenarios, enhancing its versatility and practicality.
[0073] like Figure 2 - Figure 3 As shown, in some optional embodiments, the end of the telescopic rod 50 located outside the guide rod 10 is provided with a connecting portion 51; two opposing connecting plates 511 are provided on each side of the connecting portion 51; when the telescopic rod 50 gradually enters the guide rod 10, the connecting portion 51 abuts against the end surface of the guide rod 10; the support plate 60 is provided with a rotating shaft 61, which is rotatably connected to the two connecting plates 511.
[0074] In the above technical solution, by introducing the adapter portion 51 , a connection space is provided for the rotating shaft 61 on the support plate 60 .
[0075] At the same time, the adapter portion 51 abuts against the end surface of the guide rod 10, preventing the telescopic rod 50 from accidentally or excessively entering the guide rod 10 completely, thereby ensuring that the telescopic rod 50 operates within a predetermined range. In this way, when the length of the telescopic rod 50 is adjusted, it can maintain a stable connection with the guide rod 10 without restricting the free movement of the telescopic rod 50 within the guide rod 10.
[0076] In some Figure 1 - Figure 3 In the illustrated embodiment, the high-speed camera bracket 100 further includes a buffer pad 70 provided on the support plate 60 . The buffer pad 70 is provided on a side of the support plate 60 away from the telescopic rod 50 .
[0077] The cushioning pad 70 acts as a soft medium between the contact surface of the support plate 60 and the vehicle 1000, absorbing and dissipating the impact and vibrations generated during a collision test. When the vehicle 1000 collides, the enormous energy and impact force generated may directly act on the support plate 60. Without the protection of the cushioning pad 70, these forces may be directly transmitted through the support plate 60 to the telescopic rod 50, causing damage to the high-speed camera bracket 100. The cushioning pad 70 effectively mitigates this impact, thereby protecting the safety of the high-speed camera bracket 100.
[0078] In addition to protecting the high-speed camera bracket 100, the cushioning pad 70 also protects the surface of the vehicle 1000. During the test, the bracket needs to be in close contact with the vehicle 1000 to ensure stable filming. However, if the bracket directly contacts the surface of the vehicle 1000, it may scratch or abrade the surface of the vehicle 1000, affecting the integrity of the test and the appearance of the vehicle 1000. The soft material of the cushioning pad 70 can reduce friction and damage to the surface of the vehicle 1000, ensuring a smooth test.
[0079] According to some embodiments of the present invention, a high-speed camera bracket 100 for a vehicle 1000 collision test is combined with Figure 1 - Figure 3 The guide rod 10 is a hollow circular tube, and the bushing 20 is a circular tube bushing 20 ; the mounting platform 30 is provided with at least one fixing hole 31 for fixing the camera 200 .
[0080] On the one hand, the guide rod 10 serves as a motion track for the telescopic rod 50, and its hollow design provides the necessary telescopic space for the telescopic rod 50. The hollow tube allows the telescopic rod 50 to move freely inside the guide rod 10, and the length can be adjusted as needed, thereby adjusting the shooting position and angle of the camera 200.
[0081] On the other hand, compared to solid rods, hollow tubes can significantly reduce the amount of material used. This lightweight design not only reduces the overall weight of the bracket, making it easier to install and move, but also reduces the additional load and vibration caused by weight during testing.
[0082] When the guide rod 10 is a round tube, the bushing 20 is a round tube bushing 20. A uniform circular contact surface is formed between the round tube bushing 20 and the round tube guide rod 10. This contact pattern ensures that the contact pressure between the bushing 20 and the guide rod 10 remains evenly distributed at any rotation angle, thereby reducing wear and friction caused by localized stress concentration.
[0083] Furthermore, the cylindrical bushing 20 allows the telescopic rod 50 to rotate freely within the guide rod 10 without being hindered by other shapes or structures. This rotational freedom allows the high-speed camera 200 to easily adjust the shooting angle in the horizontal or vertical direction to capture the most appropriate picture.
[0084] The main function of the fixing holes 31 is to provide a stable support point for the camera 200. By aligning these fixing holes 31 with the screw holes on the bottom of the camera 200 or the screw holes on the dedicated mounting plate and securing them with screws, bolts, or other fasteners 40, the camera 200 can be ensured not to be displaced or shaken due to vibration, impact, or other external forces during the test.
[0085] Combine Figure 2 There are four fixing holes 31 , which are respectively arranged near the four corners of the mounting platform 30 .
[0086] like Figure 4 As shown, a vehicle 1000 according to an embodiment of the second aspect of the present invention includes: a main driving cabin 1001 and a co-driver cabin 1002, and at least one of the main driving cabin 1001 and the co-driver cabin 1002 is provided with a high-speed camera bracket 100 for the collision test of the vehicle 1000 according to the embodiment of the first aspect of the present invention.
[0087] It is worth noting that the vehicle 1000 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc.
[0088] The vehicle 1000 of the present invention comprises a main driver's cabin 1001 and a passenger cabin 1002. These two areas, serving as the core driving and passenger spaces of the vehicle 1000, not only meet basic driving and riding requirements, but also house a high-speed camera mount 100 specifically designed for crash testing of the vehicle 1000. This design enables the vehicle 1000 to accurately record various data during a crash test, providing valuable information for evaluating the vehicle's safety performance.
[0089] In some embodiments, high-speed camera mounts 100 are installed in both the main driver's seat 1001 and the passenger seat 1002 of the vehicle 1000, enabling more comprehensive data collection. Furthermore, the mounting position and angle of the high-speed camera mounts 100 can be flexibly adjusted based on the test plan, ensuring optimal collision capture.
[0090] A method for vehicle collision testing is described below. The method includes placing a high-speed camera in a vehicle to be tested using the high-speed camera bracket 100 of the first embodiment of the present invention, and setting sensors on the legs of a dummy.
[0091] Optionally, before conducting a vehicle collision test, the angle and position of the high-speed camera 200 can be adjusted using the high-speed camera bracket 100 to ensure that the movement trajectory of the dummy's legs throughout the collision process, as well as the posture changes of components such as the vehicle interior, can be clearly captured.
[0092] In some optional embodiments, two sensors are provided, one on the shin and one on the thigh. This not only increases the breadth of data collected on the dummy's legs, but also helps the operator more comprehensively analyze the combined impact of a collision on the dummy's legs, thereby improving the accuracy of the test.
[0093] After the collision test begins, a high-speed camera is started to record the dynamic behavior of the dummy's legs, while sensors inside the calves and thighs begin to record the force and positioning information of the dummy's legs.
[0094] After the test, the video data captured by the high-speed camera is collected and processed to extract the movement trajectory of the dummy's legs and the changes in the vehicle interior.
[0095] Data recorded by internal sensors in the calf and thigh are used to assess the leg forces acting on the dummy during a collision.
[0096] Based on the above analysis results, operators can optimize the vehicle interior design to reduce the risk of leg injuries in a collision and ensure that the maximum compression force of the thigh does not exceed the predetermined safety threshold under frontal collision KneeMapping (KneeMapping is a term used in automotive design and safety testing. It refers to the process of evaluating and simulating the behavior and force conditions of the driver or passenger knee area during a collision in vehicle crash testing) conditions.
[0097] Adjustments made after the above tests ultimately improved the vehicle's safety performance and reduced the risk of knee and leg injuries to occupants in frontal collisions.
