[0057] Reference Figure 1 to Figure 8The utility model proposes a dynamic detection device for an electric wheelchair, which is used for detecting the electric wheelchair. The electric wheelchair has a speed control lever 110, a support wheel 120 and a front wheel 130, including a base 310 arranged on the electric wheelchair; a rotating disk 400 is rotatably arranged on the base 310; a sliding member 500 is slidably arranged on the base 310, and the sliding member 500 abuts against or moves away from the speed control lever 110 after sliding; two ends of a connecting rod 600 are respectively hingedly arranged on the sliding member 500 and the rotating disk 400, and the hinge point of the connecting rod 600 and the rotating disk 400 is not colinear with the rotation axis of the rotating disk 400.

[0058] In this embodiment, the base 310 can be fixed on the electric wheelchair by means of a clamp, magnetic adsorption or binding, so that the base 310 is fixed during the detection process, and the base 310 can be removed after the detection is completed. The sliding member 500 and the rotating disk 400 are linked by the connecting rod 600, which can simulate the driver's operation of the speed control lever 110. After adjusting the angle of the speed control lever 110 by rotating the rotating disk 400, the rotating disk 400 is fixed, so that the speed control lever 110 can be kept in a fixed position during the entire detection process. During the detection process, the speed control lever 110 can control the electric wheelchair to always be at a fixed speed, eliminating the influence on the detection result caused by the unfixed position of the speed control lever 110.

[0059] Furthermore, it also includes a first clamping wheel 700, which is slidably arranged on the rotating disk 400, and the axis of the first clamping wheel 700 is colinear with the axis of the rotating disk 400; the second clamping wheel 800 is arranged on the base 310, and the first clamping wheel 700 is clamped or separated from the second clamping wheel 800 after sliding.

[0060] Furthermore, the first clamping wheel 700 and the second clamping wheel 800 both have a plurality of teeth, and the first clamping wheel 700 and the second clamping wheel 800 are clamped by the teeth.

[0061] Furthermore, a plurality of circumferential arrays of teeth are provided on the first clamping wheel 700 and the second clamping wheel 800 .

[0062] In this embodiment, the first card wheel 700 is slidably arranged on the rotating disk 400, and the first card wheel 700 can slide relative to the rotating disk 400. The first card wheel 700 is coaxial with the rotating disk 400, so that the first card wheel 700 can maintain relatively stable linear sliding when the rotating disk 400 rotates. After the first card wheel 700 slides, it moves away from or approaches the rotating disk 400. After the first card wheel 700 slides to abut against the second card wheel 800, the second card wheel 800 and the first card wheel 700 are engaged through teeth. After the second card wheel 800 and the second card wheel 800 are engaged, the first card wheel 700 is fixed. Since the first card wheel 700 is fixed, the rotating disk 400 can no longer rotate. By fixing the rotating disk 400, the sliding member 500 can be fixed, so that the speed control lever 110 is always in the same position, eliminating the influence of the shaking of the speed control lever 110 on the experimental results.

[0063] During use, the first card wheel 700 is moved to a position away from the second card wheel 800, and the purpose of adjusting the speed control lever 110 can be achieved by rotating the rotating disk 400 or the first card wheel 700. After the speed control lever 110 is adjusted to a certain position, it is only necessary to slide the first card wheel 700 to a position where it is engaged with the second card wheel 800, so that the speed control lever 110 can be in a fixed position, so that during the detection process of the electric wheelchair, the speed control lever 110 can always be stably maintained in the same position.

[0064] Furthermore, an elastic member 900 is included, with two ends respectively disposed on the first clamping wheel 700 and the rotating disk 400 , and the elastic member 900 is used to provide a force for the first clamping wheel 700 to approach the second clamping wheel 800 .

[0065] In this embodiment, the two ends of the elastic member 900 are respectively arranged on the first clamping wheel 700 and the rotating disk 400. After the first clamping wheel 700 is rotated, it is only necessary to loosen the first clamping wheel 700. Under the action of the elastic member 900, the first clamping wheel 700 will automatically clamp with the second clamping wheel 800.

[0066] Furthermore, it also includes a detection bracket 200, which is used to place the electric wheelchair, a first support frame 210, which is arranged on the detection bracket 200, and the first support frame 210 is used to support the support wheel 120; a second support frame 220 is slidably arranged on the detection bracket 200, and the second support frame 220 slides close to or away from the first support frame 210, and the second support frame 220 is used to support the front wheel 130.

[0067] In this embodiment, the detection bracket 200 provides a stable platform for the detection process of the electric wheelchair, which is used to stably place the electric wheelchair to ensure safety and accuracy during the detection process. The electric wheelchair can be set up by the first support frame 210 and the second support frame 220. After the electric wheelchair is set up, the power wheel can be placed on the detection component to detect the speed of the power wheel, and the output efficiency of the power wheel can be detected by the detection member. The first support frame 210 can fix the support wheel 120 by fastening screws. The second support frame 220 can slide relative to the first support frame 210, and the spacing between the first support frame 210 and the second support frame 220 can be adjusted by sliding the second support frame 220, so as to adapt to wheelchairs of different sizes. The first support frame 210 can be increased with a guide rail, and the guide rail can limit the sliding of the second support frame 220 on the detection bracket 200 to ensure the stability of the sliding of the second support frame 220. After sliding, the second support frame 220 can be fixed on the guide rail of the first support frame 210 by fastening screws to prevent the position of the second support frame 220 from changing.

[0068] Further, the first support frame 210 and the second support frame 220 each have two, the two first support frames 210 are respectively used to support two support wheels, and the two second support frames 220 are respectively used to support two front wheels, and also include a first slide 230, which has two and is arranged on the detection bracket. The two first support frames 210 are respectively slidably arranged on the two first slides 230, and the two first support frames 210 move closer to or farther away from each other after sliding; the second slide 240 has two, both of which are arranged on the detection bracket, and the two second support frames 220 are respectively slidably arranged on the two second slides 240, and the sliding directions of the second support frames 220 and the first slide 230 are perpendicular to each other, and the two second support frames 220 move closer to or farther away from each other after sliding, and after the second slide 240 slides, the two first support frames 210 and the two second support frames 220 move closer to or farther away from each other. The two ends of the first damping shaft 253 are respectively arranged at the hinge points of the two second connecting rods 252; the two third connecting rods 261 are respectively arranged at the ends of the two second supporting frames 220 that are close to each other; the two fourth connecting rods 262 are respectively arranged at two ends of the fourth connecting rods 262 that are close to each other; the two ends of the second damping shaft 263 are respectively arranged at the hinge points of the two fourth connecting rods 262.

[0069] In this embodiment, the two first support frames 210 are respectively used to support two support wheels, and the two second support frames 220 are respectively used to support two front wheels. The first support frames 210 are set on the detection bracket through the first slide 230. The first support frames 210 can slide on the first slide 230. After the two first support frames 210 slide, they move closer to or away from each other, so that the first support frames 210 can be suitable for wheelchair detection with various support wheel spacings.

[0070] The two second support frames 220 are respectively used to support the two front wheels. The two second support frames 220 are respectively used to support the two front wheels. The second support frames 220 are slidably set on the detection bracket through the second slide 240. The second support frames 220 can slide on the second slide 240. After sliding, the two second support frames 220 move closer to or away from each other, so that the second support frames 220 can be suitable for wheelchair detection with various front wheel distances.

[0071] The second support frame 220 slides on the detection bracket through the second slide 240, which can be suitable for wheelchair detection with various distances between the front wheels and the support wheels. In addition, the distance adjustment between the two first support frames 210 and the two second support frames 220 can cope with the detection of wheelchairs of various sizes.

[0072] The first support frame 210 achieves the purpose of adjusting the spacing through the hinged first connecting rod 251, the second connecting rod 252 and the first damping shaft 253. This design can not only synchronize and coordinate the movement of the support frame to ensure smooth and stable movement, but also absorb vibrations and impacts during movement through the damping shaft to ensure the accuracy and safety of the equipment during the adjustment process.

[0073] The second support frame 220 achieves the purpose of adjusting the spacing through the hinged third connecting rod 261, the fourth connecting rod 262 and the second damping shaft 263, and has the same performance as the first connecting rod 251, the second connecting rod 252 and the first damping shaft 253.

[0074] Furthermore, it also includes a rotating member 221 rotatably disposed on the second support frame 220 ; a slot 222 is disposed on the rotating member 221 , and the second support frame 220 supports the front wheel 130 via the slot 222 .

[0075] In this embodiment, the second support frame 220 supports the front wheel 130 through the slot 222. The front wheel 130 in the slot 222 can prevent the electric wheelchair from sliding. The slot 222 is set on the rotating member 221, so that the slot 222 can adapt to the rotation of the front wheel 130, so as to detect the state of the electric wheelchair during the turning process of the front wheel 130.

[0076] Furthermore, it also includes a pneumatic clamp 1000, which is arranged at the end of the sliding member 500 away from the rotating disk 400. The pneumatic clamp 1000 is used to clamp the speed control rod 110. The sliding member 500 pushes or pulls the speed control rod 110 through the pneumatic clamp 1000.

[0077] In this embodiment, the pneumatic clamp 1000 can clamp the speed control rod 110, not only can the speed control rod 110 be pushed, but also the pneumatic clamp 1000 can be driven to slide in the opposite direction through the sliding member 500, pulling the speed control rod 110 to tilt in the opposite direction. After the pneumatic clamp 1000 clamps the speed control rod 110, the speed control rod 110 is adjusted, so that the adjustment process of the speed control rod 110 is more stable.

[0078] Furthermore, it also includes a fixed block 320 set on the base 310; a sliding block 330 is slidably set on the base 310, and the sliding block 330 slides close to or away from the fixed block 320. There is a clamping space between the fixed block 320 and the sliding block 330, and the clamping space is used to clamp the electric wheelchair.

[0079] In this embodiment, the sliding block 330 and the fixed block 320 are used to fix the base 310 on the electric wheelchair. The sliding block 330 can clamp the electric wheelchair by sliding close to the fixed block 320. The side of the base 310 away from the sliding block 330 and the fixed block 320 is a plane, which is more conducive to the arrangement of the rotating disk 400 and the sliding member 500.

[0080] Furthermore, the base 310 has a threaded hole, and the base 310 also includes a screw rod 340 rotatably disposed on the base 310 , the screw rod 340 is engaged with the threaded hole, and the sliding block 330 is disposed at one end of the screw rod 340 .

[0081] In this embodiment, the screw rod 340 is rotated. Since the base 310 is fixed on the electric wheelchair, the screw rod 340 will push the sliding block 330 to be closer to or away from the fixed block 320. By adjusting the sliding block 330 through the screw rod 340, not only the sliding process of the sliding block 330 is made more stable, but also the clamping force between the sliding block 330 and the fixed block 320 is easier to control.

[0082] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
