Problems solved by technology
According to the requirements of my country's technical standards, the wheelchair can pass through obstacles with a drop of 10cm at most during the process of travel. Generally, this indicator will inevitably cause the diameter of the front wheel to increase (for example, up to 30cm). In actual situations, this will cause the wheelchair to bump greatly, and even roll over. danger

Embodiment Construction
[0014] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0015] An intelligent wheelchair moving obstacle-surmounting device comprises an obstacle-crossing sensing device and an obstacle lifting device.
[0016] Obstacle clearance sensing devices such as figure 1 As shown, the strain sensor is fixed on the reed, one end of the reed is fixed on the wheelchair, and the other end is connected with the front wheel anti-vibration rod through the connector; When the sheet is bent, the strain sensor sends out a signal for processing and analysis by the processor.
[0017] Obstacle lifting devices such as figure 2 As shown, one end of the connecting rod is connected to the support whe...

The invention relates to an intelligent moving and obstacle-surmounting device of a wheelchair. The device includes an obstacle sensing device body and an obstacle-surmounting lifting device body; the obstacle sensing device body includes a vibration-avoiding rod, a connector, a spring and a strain sensor, wherein the vibration-avoiding rod is connected with a wheelchair-driving front wheel, the connector is connected with the vibration-avoiding rod, the spring is connected with the connector, and the strain sensor is arranged on the spring; the obstacle-surmounting lifting device body includes a supporting wheel, a connecting rod connected with the supporting wheel, and an electric pull rod connected with the connecting rod; the strain sensor receives an obstacle signal and transmits the signal to a processor for processing and analyzing, and then the obstacle-surmounting lifting device is started to work. The device can easily surmount the obstacle (including a pit) with the level difference of about 10 cm, the moving state of the wheelchair is smooth and steady, the cost is low, and the device is safe, reliable and durable.
Description
technical field [0001] The invention relates to an intelligent wheelchair advancing and overcoming obstacles device. Background technique [0002] At present, our country is carrying out various technological innovations in the intelligent technology of wheelchairs, and the functions are gradually improved. According to the requirements of our country's technical standards, the wheelchair can pass through obstacles with a maximum drop of 10cm during the process of travel. Generally, this indicator will inevitably cause the diameter of the front wheel to increase (for example, up to 30cm). In actual situations, this will cause the wheelchair to be bumpy and even overturned. danger. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose an intelligent wheelchair advancing obstacle-surmounting device, through structural optimization design and automatic control, it can better realize smooth obstacle-surmounting and improv...
