The use of the annular slide rail 18 in combination with the annular slider 20 can improve the stability of the rotation of the annular seat 19 in the annular groove 17.
In this embodiment: hair comb assembly, specifically including: the movable block 37 which is movably connected inside the notch 36 and matched with the notch, a second spring column 38 is fixedly connected between one end of the movable block 37 and the inner wall of the notch 36, the other end of the movable block 37 is an inclined surface, inclined surfaces matched with the inclined surfaces of the movable block 37 are arranged on two sides of the end part of the square rod 32, and a side surface of the movable block 37 is fixedly connected with a comb tooth 39. The hair comb assembly is capable of combing hair at the head of a user to be attached to the two sides, thereby facilitating better contact with the head of the user by the collection patch 28 and improving accuracy of signal collection.
In this embodiment: positioning grooves 34 are formed in the inner walls of the two sides of the square hole 31, and positioning heads 35 matched with the positioning grooves 34 are fixedly connected to the two side faces of the square rod 32. After the square bar 32 is pressed into the square hole 31, the positioning head 35 is clamped into the positioning groove 34 while the collection patch 28 is in contact with the head of the patient, so that the square bar 32 cannot be easily moved, and the stability of the square bar 32 in the detection process is improved.
In this embodiment: the other end of the square rod 32 is embedded with a conductive head 33, and an energizing wire is arranged between the conductive head 33 and the collecting patch 28. The application adopts split type collection paster 28, will gather the conducting head 33 that the paster 28 corresponds when using and be connected with external wire, separation when not using is convenient to accomodate the management.
The working principle of the invention is as follows: when the head signal of the user on the wheelchair needs to be collected, the originally stored annular head cover 13 is firstly adjusted to be in a working state, specifically: the rotating motor 6 operates to drive the screw rod 7 to rotate, the lifting seat 8 slowly ascends along the strip-shaped groove 5 until the lifting seat 8 is propped against the top of the strip-shaped groove 5, then, the stepping motor 11 operates to drive the first connecting rod 10 to turn ninety degrees around the rotating groove 9, so that the annular head cover 13 which is originally in a vertical state is changed into a horizontal state, then, the two arc plates 15 are opened from the step groove 14 immediately before a worker goes up, namely, the arc plates 15 rotate by a proper angle around the rotating shaft 16, and then, the screw rod 7 is driven to reversely rotate by the rotating motor 6 to lower the annular head cover 13 by a certain height according to the head height of a user, so that the annular head cover 13 can be smoothly sleeved on the head of the user.
The balls 27 exposed from the circular grooves 26 can reduce the resistance to the user's head when wearing the annular head cover 13 when the annular head cover 13 is fitted over the user's head. In addition, the staff can adjust the adjustable guide assembly according to the needs of patients and the environment, namely when the adjusting rod 30 is shifted to one end of the arc-shaped groove 29, the annular seat 19 in the annular groove 17 rotates relatively, and the metal balls 27 are clamped in the annular groove 26. When the adjusting lever 30 is shifted to the other end of the arc groove 29, the annular seat 19 in the annular groove 17 also rotates relatively, and the ball 27 of rubber is clamped in the circular groove 26. When the adjusting rod 30 is shifted to the middle position of the arc-shaped groove 29, the ball 27 is not arranged in the round groove 26 after the annular seat 19 rotates. It should be noted that, the ball 27 made of metal is suitable for hot weather, the thermal conductivity of metal is good, can absorb the heat of user's head fast, improves the comfort level when the user wears annular headgear 13, and the ball 27 made of rubber is suitable for severe cold weather, and the heat preservation effect of rubber is good, can avoid ball 27 and user contact position to stab more cold under severe cold weather, improves the comfort level when the user wears annular headgear 13. If the user feels uncomfortable when the ball 27 is in contact with the head, the ball 27 can be required to be adjusted to be in a non-exposed state, so that the device has wider applicability and effectively improves the use experience of the user.
When the annular head cover 13 is fitted over the user's head, the comb teeth 39 on the hair comb assembly also contact the user's head. At this time, the worker presses the square bar 32 down toward the square hole 31 before going up, and the positioning head 35 is clamped into the positioning groove 34 while the collecting patch 28 is in contact with the head of the patient, so that the square bar 32 cannot be easily moved, thereby improving the stability of the square bar 32 in the detection process. In the process that the square rod 32 goes deep into the square hole 31, the end part of the square rod 32 and the moving blocks 37 on two sides are subjected to inclined plane action, the moving blocks 37 on two sides are pushed to move to two sides respectively, the second spring column 38 is compressed, the upper comb teeth 39 comb the hair on the position to two sides along with movement in the process that the two moving blocks 37 are mutually far away from each other, and the acquisition patch 28 on the end part of the square rod 32 goes deep is contacted with the detection position with less hair, so that the acquisition patch 28 is conveniently contacted with the head of a user better, and the accuracy of signal acquisition is improved. Finally, the conductive heads 33 corresponding to the collecting patches 28 are connected with external wires to collect head signals.
After the head signal of the user is collected and contacted, the external lead connected with the conductive head 33 is firstly detached, and then the square rod 32 is pulled upwards from the square hole 31, so that the positioning head 35 is separated from the positioning groove 34, and in the process, the second spring column 38 releases elastic potential energy to restore the moving block 37 to the original position, so that the next use is convenient. Then the annular head cover 13 is lifted to the highest position through the rotating motor 6 and the screw rod 7 to be separated from the head of a user, the original horizontal annular head cover 13 is restored to the vertical state through the stepping motor 11, and finally the annular head cover 13 is lowered to the original position through the rotating motor 6 and the screw rod 7, so that the annular head cover 13 is stored and the normal use of the wheelchair by the user is not affected.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
The foregoing description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical solution of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
