Description

Technical Field

[0001] The present invention relates to the technical field of dynamic balance of electric wheelchair drive wheels, and specifically relates to a dynamic balance detection device for electric wheelchair drive wheels. Background Art

[0002] An electric wheelchair is upgraded by superimposing high-performance power drive devices, intelligent control devices, batteries and other components on the basis of a traditional manual wheelchair. It is a new generation of intelligent wheelchair that can drive the wheelchair to complete various functions such as forward, backward, turning, standing, lying flat, etc. with an artificial operation of an intelligent controller. It is a high-tech product that combines modern precision machinery, intelligent numerical control, engineering mechanics and other fields.

[0003] Currently, when installing a drive device on an existing electric wheelchair, it needs to be detected. During the detection, first place the drive device on the workbench, then fix it. After fixing, power it on. After powering on, visually observe the rotation of the drive wheel with the naked eye. If the drive wheel shakes during rotation, it means that the drive device has a dynamic balance problem. If there is no problem, the drive device is normal. Then the drive device can be installed on the wheelchair to complete the installation of the electric wheelchair.

[0004] Currently, when detecting the dynamic balance of existing drive devices, most of them rely on staff to visually judge whether there is a dynamic balance problem with the drive wheels in the drive device. If there is a small shake when the drive wheel rotates, it may be impossible for the staff to observe it with the naked eye, resulting in a poor overall detection effect and a large detection error for the entire drive device.

When the detection is completed, the detection component 10 is removed from one side of the driving wheel. After removal, it is convenient to remove the driving component 8.

[0039] Embodiment 3

[0040] As Figures 1-8 shown, on the basis of the above embodiment, the present embodiment further gives the following content:

[0041] In order to improve the detection efficiency of the driving assembly, the following design is given:

[0042] The quick-change component 7 includes a first placement plate 71. The two ends of the upper end surface of the base 2 are respectively provided with the first placement plate 71. The lower ends of the first placement plates 71 are respectively fixedly connected with a first rack 72 and a first rectangular rod 73. The first rectangular rod 73 is slidably connected to the inner cavity of the base 2. A chute 74 is arranged on the upper end surface of the first rack 72. A limiting block 75 is slidably connected to the inner cavity of the chute 74. The limiting block 75 is fixedly connected to one side of the base 2. The quick-change component 7 further includes a second rectangular rod 76 and a second rack 77. The second rectangular rod 76 and the second rack 77 are respectively slidably connected to the inner cavity of the base 2. One end of the second rectangular rod 76 and the second rack 77 is fixedly connected with a second placement plate 78. One side of the second rack 77 is meshed with a gear 79. The outer surface of the gear 79 is meshed with the first rack 72. The gear 79 is rotatably connected to one side of the base 2. Long limiting strips 710 and short limiting strips 711 are respectively fixedly connected to the upper end surfaces of the first placement plate 71 and the second placement plate 78.

[0043] Through the mutual cooperation of the first placement plate 71, the second placement plate 78, the gear 79, the first rack 72, and the second rack 77 in the quick-change component 7, the rapid replacement of the driving component 8 is realized, the installation of another set of driving components 8 is realized during the detection process, the replacement of the two is realized, and the overall detection efficiency is increased.

[0044] The working principle and usage process of the present invention:

[0045] In the usage state:

[0046] Quick replacement of the drive component: First, place the drive component 8 to be detected on the quick replacement component 7, and then limit the drive motor 81 through the long limit bar 710 and the short limit bar 711 in the quick replacement component 7 respectively. When limiting, make the long limit bar 710 and the short limit bar 711 contact the outer surface of the drive motor 81 respectively. After contact, the staff then pushes the first placement plate 71. When the first placement plate 71 moves, it will drive the first rectangular rod 73 and the first rack 72 to move respectively. When the first rectangular rod 73 moves, it will slide in the inner cavity of the base 2. When the first rack 72 moves, it will move on the limit block 75 through the chute 74. When the first rack 72 moves, it will drive the gear 79 to rotate. When the gear 79 rotates, it will drive the second rack 77 to move. When the second rack 77 moves, it will drive the second placement plate 78 to move. When the second placement plate 78 moves, it will move out from the base 2. At this time, the first placement plate 71 will drive the drive component 8 to move upward to the upper part of the base 2. When the second placement plate 78 is moved out and at the same time the first placement plate 71 is moved to the upper part of the base 2, stop moving the first placement plate 71, and place a set of drive components 8 on the second placement plate 78 for convenient later detection. This will increase the overall work efficiency. When the first placement plate 71 moves to the upper part of the base 2, rotate the positioning screw rod 111. When the positioning screw rod 111 rotates, it will drive the positioning block 112 to move downward. When the positioning block 112 moves downward, under the action of the limit rod 113, the positioning block 112 will move smoothly downward. When the positioning block 112 moves downward, it will start to clamp the upper end surface of the drive motor 81. Thus, through the mutual cooperation of the first placement plate 71, the long limit bar 710 and the short limit bar 711, the fixation of the drive motor 81 is achieved;

[0047] Positioning and clamping: When the positioning block 112 moves downward, it will drive the first L-shaped rod 114 to move downward. When the first L-shaped rod 114 moves downward, it will drive the first inclined block 116 and the second inclined block 117 to move downward. When the first inclined block 116 begins to squeeze the second L-shaped rod 115, the second L-shaped rod 115 will drive the longitudinal rod 103 to move in the first T-shaped groove 102. When the longitudinal rod 103 moves, it will drive the rectangular sleeve 106, the rectangular block 1010 and the detection wheel 1012 to move closer to the driving wheel 82 as a whole. When the detection wheel 1012 is in contact with the hub on the driving wheel 82, at this time, the positioning block 112 will also contact the upper end surface of the driving motor 81. When replacing the driving component 8, then rotate the positioning screw rod 111. The positioning screw rod 111 will drive the positioning block 112 to move upward. When the positioning block 112 moves upward, it will drive the detection wheel 1012 away from the driving component 8 through the cooperation of the second inclined block 117 and the second L-shaped rod 115, thus facilitating the replacement of the driving component 8 in the later stage. This design is convenient for detection on the one hand and convenient for replacing the driving component 8 in the later stage on the other hand.

[0048] During detection: First, move the copper block 1020 to a suitable position through the I-shaped block 1018 and the arc-shaped groove 1017, ensuring that the error within this range is qualified during subsequent detection. Any error greater than this range is considered unqualified. When the copper block 1020 is adjusted to the appropriate position, then tighten the fixing bolt 1019. At this time, the copper block 1020 can be fixed through the friction between the fixing bolt 1019 and the sector plate 1014. After the copper block 1020 is fixed, insert the female head 84 in the drive assembly 8 to be detected into the power socket 5. After insertion, control the controller 3 through the control panel 4, and then the controller 3 supplies power to the drive motor 81. When the drive motor 81 operates, it will drive the drive wheel 82 to rotate. When the drive wheel 82 rotates, it will be detected by the detection wheel 1012. During detection, first, the detection wheel 1012 will rotate along with the drive wheel 82 (note: the detection wheel 1012 rotates on its own axis). When the detection wheel 1012 rotates and is subjected to a force from the left, the detection wheel 1012 starts to squeeze the rectangular block 1010, and the rectangular block 1010 starts to squeeze the third damping rod 109. Since a spring is sleeved outside the third damping rod 109, the spring is squeezed. At the same time, the rectangular block 1010 will drive the second V-shaped block 1011 to move. When the second V-shaped block 1011 moves, it will drive the second pointer 1016 to deflect. When the angle of rotation of the second pointer 1016 is within a certain range and does not hit the copper block 1020, it is qualified. When the second pointer 1016 hits the copper block 1020 and the hits are frequent, it is unqualified. When the drive wheel 82 moves to the right, although the detection wheel 1012 is not subjected to force at this time, to ensure the contact between the detection wheel 1012 and the hub, the third damping rod 109 will drive the rectangular block 1010 and the detection wheel 1012 to move towards the drive wheel 82, and this will also cause the second pointer 1016 to deflect for detection;

[0049] During detection, when the detection wheel 1012 moves back and forth, the detection wheel 1012 will drive the rectangular block 1010 and the rectangular sleeve 106 to slide in the second T-shaped groove 105. When the rectangular sleeve 106 moves back and forth, it will drive the first V-shaped block 107 to move back and forth. When the first V-shaped block 107 moves back and forth, it will drive the first pointer 1015 to swing. When the swing range is between the copper blocks 1020, it is qualified. When it is greater than this range, it is unqualified. When the rectangular sleeve 106 moves back and forth, it will start to squeeze the second damping rod 108. Since a spring is sleeved outside the second damping rod 108, the external spring is compressed. When the second damping rod 108 is not subjected to external extrusion, the second damping rod 108 will drive the rectangular sleeve 106 and the detection wheel 1012 to reset for the next detection.

[0050] In general, through the mutual cooperation of the quick-change component 7 and the detection component 10, the quick replacement of the drive component 8 is achieved, and the subsequent detection is facilitated.
