[0003] Existing gait behavior acquisition devices consist of a gait test platform and an image acquisition device facing the gait test platform. The gait test platform allows the target object to walk on it, and the image acquisition device captures images of the target object's gait for later gait analysis.

[0004] However, to ensure the integrity of the analysis, gait analysis requires the acquisition of multiple gait images under various walking environments. Existing gait behavior acquisition devices cannot adjust the state of the gait test platform according to various environments, resulting in a limited number of gait images acquired.

[0033] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Please see Figures 1 to 5 The image shows a gait behavior acquisition device according to one embodiment of the present invention, including a machine base 100 with a support frame 110, a gait test platform 200 for mounting on the machine base 100, an image acquisition device 300, and a multi-directional adjustment bracket 400. It should be noted that the gait test platform 200 can be constructed using existing track, track frame, and drive motor. That is, the drive motor can drive the track to move forward or backward, so that the target object can walk in two directions on the gait test platform 200. In some optional embodiments, the gait test platform 200 can have a speed adjustment function, such as using a drive motor to adjust the speed of the track.

[0037] To address the technical problem that existing gait behavior acquisition devices cannot adjust the state of the gait test platform according to various environments, resulting in limited gait image acquisition, in this example, the middle part of the gait test platform 200 is rotatably connected to the support frame 110, so that when the middle part of the gait test platform 200 rotates around the pivot point, the gait test platform 200 is tilted relative to the machine platform 100.

[0038] The multi-directional adjustment bracket 400 is used to connect the image acquisition device 300 to the machine platform 100. The multi-directional adjustment bracket 400 is used to adjust the position of the image acquisition device 300 according to the tilt angle of the gait test platform 200, so that the shooting range of the image acquisition device 300 is directly opposite the gait test platform 200.

[0039] In practical implementation, the gait test platform 200 is rotatably connected to the support frame 110 at its center. This allows the gait test platform 200 to be tilted relative to the machine base 100 during gait image acquisition. Different tilt states of the gait test platform 200 can simulate different acquisition environments, enabling the acquisition of gait images under different testing environments during gait analysis. This ensures the integrity of the gait images during gait analysis and solves the technical problem of limited gait image acquisition in existing technologies. In this example, a multi-directional adjustment bracket 400 can be used to connect the image acquisition device 300 to the machine base 100. After the gait test platform 200 is adjusted, the position of the image acquisition device 300 can be adjusted using the multi-directional adjustment bracket 400, ensuring that the image acquisition range of the image acquisition device 300 is always directly facing the gait test platform 200. Finally, the image acquisition device 300 is used to acquire images, further ensuring the effectiveness of the gait images during acquisition.

[0040] It should be noted that in some preferred embodiments, a servo motor can be arranged on the support frame 110 to drive the gait analyzer to rotate, and the image acquisition unit 300 can be a high-speed optical camera in the prior art.

[0041] In addition, in this example, the multi-directional adjustment bracket 400 includes a slider 410 and two rods rotatably connected to each other. The slider 410 is used to slide the image acquisition device 300 onto one of the two rods, and the other rod is slidably connected to the machine base 100.

[0042] Specifically, the two support rods are a first support rod 420 and a second support rod 430, and the ends of the first support rod 420 and the second support rod 430 that are close to each other are rotatably connected. The first support rod 420 is slidably connected to the machine base 100, and the sliding member 410 is slidably connected to the second support rod 430.

[0043] In some preferred embodiments, a cylinder can be arranged on the machine base 100 to drive the first support rod 420 to move laterally. At the same time, the second support rod 430 can be adjusted in the left and right angle relative to the first support rod 420 by rotating with the first support rod 420. For example, the second support rod 430 can be perpendicular to the first support rod 420, or it can be tilted relative to the first support rod 420. By adjusting the angle of the second support rod 430, the sliding member 410 can drive the image acquisition device 300 to adjust its position under the interaction of the first support rod 420 and the second support rod 430. Furthermore, when the image acquisition device 300 is not in use, the second support rod 430 can be folded to fold the image acquisition device 300 onto the surface of the machine base 100.

[0044] In addition, in some practical situations, the acquisition of gait images also needs to ensure the stability of the target object walking on the gait test bench 200. The acquisition device in this example also includes at least one suspension component 500, at least one grip component 600 and at least one binding component 700 disposed on the machine 100. The suspension component 500 is directly opposite the middle of the gait test bench 200 and is used to suspend the middle of the target object located on the gait test bench 200. The suspension component 500 is disposed between the grip component 600 and the binding component 700.

[0045] Specifically, in this example, the suspension assembly 500 includes a first cantilever 510, a first strap 520, and a first connector 530 for connecting the first strap 520 to the first cantilever 510. The end of the first cantilever 510 away from the first connector 530 is rotatably connected to the machine base 100. By rotating the first cantilever 510, the relative height of the first strap 520 can be adjusted. The first strap 520 is used to bind the middle of the target object.

[0046] The grip assembly 600 includes a second cantilever 610, a grip 620, and a second connector 630 for connecting the grip 620 to the second cantilever 610. The end of the second cantilever 610 away from the second connector 630 is rotatably connected to the machine base 100. The relative height of the grip 620 is adjusted by rotating the second cantilever 610.

[0047] The binding assembly 700 includes a third cantilever 710, a second binding strap 720, and a third connector 730 for connecting the second binding strap 720 to the third cantilever 710. The end of the third cantilever 710 away from the third connector 730 is rotatably connected to the machine base 100. The relative height of the second binding strap 720 can be adjusted by rotating the third cantilever 710.

[0048] In practice, the second cantilever 610 and the grip bar 620 can support the upper limbs of the target object, the first cantilever 510 and the first strap 520 can fix the body of the target object, and the third cantilever 710 and the second strap 720 can bind the tail of the target object to help determine the direction of movement and stabilize the gait of the test object.

[0049] It should be noted that the target subjects mentioned above can be laboratory mice.

[0050] Furthermore, the suspension assembly 500 may also include a weight measuring device 540, which is located between the first strap 520 and the first connector 530. That is, the weight measuring device 540 can measure the suspended weight of the target object, and the weight of the target object can be precisely reduced by adjusting the height of the first connector 530. Specifically, the weight measuring device 540 may be a tension sensor in the prior art.

[0051] It should be noted that the first cantilever 510, the second cantilever 610 and the third cantilever 710 mentioned above can all be driven to rotate by arranging three servo motors in the machine tool 100. In addition, the first connector 530, the first connector 530 and the third connector 730 shown in this example can be made of flexible rope or rigid tube as in the prior art.

[0052] In addition, to achieve automated control of the tilt angle of the gait testing platform 200, the movement state of the multi-directional adjustment bracket 400, the working state of the image acquisition device 300, the working state of the first cantilever 510, the working state of the second cantilever 610, and the working state of the third cantilever 710, a controller can be arranged inside the machine 100. The controller can automatically control the gait testing platform 200, the multi-directional adjustment bracket 400, the image acquisition device 300, the first cantilever 510, the second cantilever 610, and the third cantilever 710. In some preferred embodiments, a start / stop switch 800, an emergency stop switch 900, and a caliper 910 can also be arranged on the machine 100. The start / stop switch 800 can control the start and stop of the gait behavior acquisition device, the emergency stop switch 900 can quickly shut down the gait behavior acquisition device, and the caliper can provide a reference for the tilt angle of the gait testing platform 200 and the position of the image acquisition device 300.

[0053] In summary, the gait behavior acquisition device according to an embodiment of this utility model has at least the following advantages compared to existing gait behavior acquisition devices:

[0054] In the gait behavior acquisition device of this utility model, the gait test platform 200 is rotatably connected to the support frame 110 at its center. This allows the gait test platform 200 to be tilted relative to the machine base 100 during gait image acquisition. Different tilt states of the gait test platform 200 can simulate different test environments, enabling the acquisition of gait images under different test environments during gait analysis. This ensures the integrity of the data during gait analysis and solves the technical problem of limited gait image acquisition in the prior art. In this example, a multi-directional adjustment bracket 400 can be used to connect the image acquisition device 300 to the machine base 100. After the gait test platform 200 is adjusted, the position of the image acquisition device 300 can be adjusted by the multi-directional adjustment bracket 400, ensuring that the imaging range of the image acquisition device 300 is always directly facing the gait test platform 200. The image acquisition device 300 is used to acquire gait images, thereby achieving gait image acquisition and further ensuring the effectiveness of the gait image acquisition.
