Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1-3 illustrate a walking stick cane 10 that functions as a support aid in some embodiments of the present invention. The intelligent crutch 10 comprises a support mechanism 1 capable of being adjusted in a telescopic mode and an electronic auxiliary mechanism 2 arranged on the support mechanism 1; the support mechanism 1 capable of being adjusted in a telescopic mode can be adjusted to be different in length through telescopic adjustment so as to adapt to users with different heights, and universality is improved; the electronic assistant mechanism 2 plays a role in enriching the functions of the intelligent crutch 10.

The supporting mechanism 1 comprises a telescopic piece 11 and a holding piece 12 provided with a holding section 121 and a sensing section 122; the holding section 121 has a storage cavity 1211 formed therein, and the sensing section 122 is disposed on the telescopic member 11 and has a detection avoiding hole 1221.

It can be understood that the telescopic manner of the telescopic member 11 can be manually adjusted to be telescopic, or can be adjusted to be telescopic by structures such as a motor screw rod and the like, and is specifically adjusted according to the user requirements. The grip 12 is for gripping by a user. The receiving cavity 1211 plays a role of receiving the remaining components. The detection clearance hole 1221 plays a role in opening a detection gap, so that the parts for detection are prevented from being blocked, and the normal work of the parts for detection is ensured.

The electronic assisting mechanism 2 includes a direction adjusting member 27 provided in the housing chamber 1211, and a momentum motor 25 provided on the direction adjusting member 27; wherein, the direction adjusting member 27 can adjust the orientation of the momentum wheel 22 when rotating, and the momentum wheel 22 can generate the traction force and transmit the traction force to the grip 12 by the driving of the momentum motor 25.

As will be appreciated, the momentum motor 25 is used to drive the momentum wheel 22 to rotate, the momentum wheel 22 rotating about its own central axis; different rotational directions will cause different deviations in the center of gravity of the momentum wheel 22, which in turn will cause different directions of swinging tendency of the grip 12.

It should be noted that, the momentum wheel 22 rotates to generate centrifugal force, the centrifugal force is transmitted to the holding part 12 to generate traction force, on this basis, the direction of the centrifugal force is adjusted by the rotation of the direction adjusting part 27, that is, the traction force in different directions can be transmitted to the customer through the holding part 12, and the direction of the traction force can be obtained by combining with the obstacle avoidance track on the basis of the navigation route, so as to guide the user to move forward correctly; the different rotational speeds of the momentum wheel 22 may generate different amounts of traction, and in view of this, different amounts of traction may be generated according to the deviation degree of the current travel trajectory and travel direction from the predetermined travel trajectory and predetermined travel direction, preferably, the deviation degree is proportional to the traction amount.

The navigation route can be determined through the navigation positioning module, and the obstacle avoidance track can be formed by components and parts which can identify obstacles in a preset range in related technologies such as a camera, a sensor and a radar. Specifically, the radar may be one or more of various radars in related technologies such as an ultrasonic radar, a millimeter wave radar, a laser radar, and the like; the sensor may be an infrared sensor or any other sensor capable of detecting an obstacle.

As shown in fig. 3, the electronic assisting mechanism 2 may further include several vision cameras 24 disposed in the detection avoiding hole 1221 in some embodiments; the detection end of each vision camera 24 faces the outside of the detection avoiding hole 1221, and the detection directions of each vision camera 24 are axisymmetrically distributed with the central axis of the induction section 122.

It can be understood that the detection direction of each vision camera 24 is the direction of the camera of each vision camera 24, and the detection direction of each vision camera 24 is distributed in axial symmetry along the central axis of the sensing segment 122, so that each vision camera 24 can be fully utilized, the detection areas of two adjacent vision cameras 24 are prevented from being overlapped too much, and the detection area of each vision camera 24 is enlarged as much as possible.

It is also understood that a battery pack or the like for supplying power to the electronic assisting mechanism 2 may be provided on the intelligent crutch 10, and a processor or the like may be provided for processing information of the electronic assisting mechanism 2 and controlling the electronic assisting mechanism 2 to operate integrally.

As shown in fig. 1 and fig. 2, the intelligent crutch 10 may further include a direction adjustment motor 28 disposed in the accommodating cavity 1221, the direction adjustment motor 28 is in driving connection with the direction adjustment member 27, and the direction adjustment member 27 can be driven by the direction adjustment motor 28 to rotate in the horizontal direction.

It is understood that the direction adjustment motor 28 can drive the direction adjustment member 27 to rotate in forward or reverse direction, and the connection between the two can be direct connection or indirect connection such as a transmission gear train. Specifically, various connection manners in the prior art are possible, as long as the direction adjusting member 27 can drive the momentum wheel to generate centrifugal forces in different directions toward different positions, so as to perform traction in different directions on the user.

As shown in fig. 1 and 2, the electronic assisting mechanism 2 may further include a vibrating member 21 disposed in the receiving cavity 1211 in some embodiments; the vibrating member 21 may drive the grip section 121 to vibrate when powered, and the vibration may also be transmitted to the user through the grip section 121.

As can be understood, the vibrating element 21 is used for generating vibration when powered on, and the input voltages with different magnitudes correspond to different vibration frequencies, and the different vibration frequencies correspond to different indication information when transmitted to the user; for example, the vibration amount is larger when the advancing direction is wrong, the vibration amount is further increased when an obstacle exists in the advancing direction, the vibration amount is reduced or disappears after obstacle avoidance, and the like, and the setting is specifically performed according to the actual application requirements.

Specifically, the vibrator 21 may include a vibration motor 211 fixedly disposed in the receiving cavity 1211 and an eccentric 212 connected to the vibration motor 211 in some embodiments. The eccentric wheel 212 can be eccentrically rotated by the vibration motor 211, so as to drive the vibration motor 211 to vibrate.

It will be appreciated that when the vibration motor 211 is energized, the eccentric 212 is driven to rotate, and the rotational axis about which the eccentric 212 rotates does not coincide with the central axis of the eccentric 212, such that the center of gravity of the eccentric 212 does not coincide with the central position of the eccentric 212, resulting in the eccentric 212 being able to vibrate when active, the vibration being transmitted by the vibration motor 211 to the grip 12 and thus to the user's hand.

It can be understood that the higher the rotation frequency of the eccentric wheel 212, the larger the vibration amount transmitted to the hand of the user, and different vibration amounts prompt the user with different information.

The first rod 112 and the second rod 113 together function to adjust the relative position of the grip 12 and the flexible support 111 to support the grip 12. The clamping structure 114 can be used to fix the relative positions of the first rod 112 and the second rod 113, so as to fix the distance from the grip 12 to the flexible support 111, and also release the clamping fit relationship between the first rod 112 and the second rod 113, so as to re-align the distance between the grip 12 and the flexible support 111.
