The metal connection points 313 corresponding to the number of the elastic protrusions 303; when the walking aid split body 2 is assembled on the wheelchair main body 1, the elastic protrusions 303 and the connecting point 313 can form the connection between the walking aid split body 2 and the wheelchair main body 1. electrical conduction. A mechanism for electrical communication is provided between the wheelchair main body 1 and the walking aid split 2, which can form a circuit connection between the two when the assembly is completed, which is convenient for electrical components and intelligent equipment on the wheelchair main body 1 and the walking assistant split 2. setting.

There are various options for the above-mentioned operating device; however, due to the setting of the rollers 208 on the walking aid split body 2 , the walking aid split body 2 is generally equipped with an operating lever 206 , and the operating rod 206 is generally arranged on the side of the supporting portion 205 . The lower part is hinged to the support part 205 through a rotating shaft, and is equipped with a pull wire 207 to form a brake for each roller 208 . Based on the setting of the pull wire 207 , in this embodiment, the operating device is realized by using the operation lever 206 and the pull wire 207 . As shown in FIG. 8 , the left end of the claw 411 is connected to the pull wire 207, and the end of the connecting plate 3111 is connected to the pull wire 207 at the same time; when the operating lever 206 is operated, the second assembly part 3 and the first assembly part 3 can be unlocked at the same time. Assembly part 4. The pulling wire 207 is used as the operation connecting piece, the claw 411 and the movable hook 311 can be operated at the same time. The disassembly between the walking aid split body 2 and the wheelchair main body 1 is very convenient.

Regarding the relative positions of the second assembly part 3 and the first assembly part 4 , on the same walking aid body 2 , the two can be arranged at intervals. Preferably, the second assembly part 3 is arranged on the first assembly part 4 above. Of course, the number of the second assembly parts 3 and the first assembly parts 4 can also be increased to improve the assembly firmness of the auxiliary walking device installed on the wheelchair body 1 .

It should be noted here that after the auxiliary walking device is installed on the wheelchair main body 1 through the second assembly part 3 and the first assembly part 4, a certain gap should be kept between the lowermost end of the auxiliary walking device and the ground, so that When the wheelchair is moving, turning or retreating, the bottom of the assistive walking device will not rub against the ground. When a universal wheel is installed at the bottom of the walking aid split body 2, the contact with the ground will not hinder the movement of the wheelchair; , if its bottom is in contact with the ground, it will affect the normal movement of the wheelchair.

Therefore, when the auxiliary walking device supported on the ground in the use state is close to the wheelchair main body 1 , the part of the second assembly part 3 and the first assembly part 4 located on the wheelchair main body 1 is opposite to the part located on the separate walking aid body 2 It should be slightly higher; for example, the positioning part 402 on the wheelchair main body 1 should be slightly higher than the positioning matching part 414 on the walking aid split body 2 . The positioning part 402 and the positioning matching part 414 can be aligned by gently lifting the walking split body 2 with both hands, so as to complete the suction and locking of the first assembly part 4 , and then complete the hooking and fixing of the second assembly part 3 even.

The split-type auxiliary walking device adapted to the wheelchair described in this embodiment adopts a split-type structure for the detachable auxiliary walking device disposed on the wheelchair main body 1, which can be symmetrically placed on the wheelchair main body 1. The two sides will not affect the normal use of the wheelchair main body 1; when using the split-type auxiliary walking device adapted to the wheelchair, the first connecting member 5 can be conveniently used to assemble the two walking-aid splits 2 The auxiliary walking device is formed as a whole, which is convenient for walking and exercising, so that the adaptability of the auxiliary walking device in the integrated assembly of the wheelchair can be improved.

Embodiment 2

The wheelchair equipped with the assisting walking device in this embodiment includes a wheelchair main body 1 and a walking assistance sub-body 2 that can be detached and assembled on the wheelchair main body 1 . The disassembly structure and connection structure described in Example 1.

Still as shown in FIG. 1 and FIG. 4 in the first embodiment, the walking aid sub-body 2 has two supporting parts 205 arranged symmetrically, for example, can be designed in the shape of an armrest. When the walker body 2 is assembled on the wheelchair body 1 , the two armrests are placed on both sides of the upper part of the wheelchair body 1 , so as to constitute support for the arms of the human body sitting on the wheelchair body 1 . The two handrails used for the walking aid split 2 are located at the armrest position of the wheelchair main body 1 when the walking assistant split 2 is assembled on the wheelchair main body 1, thus realizing the dual purpose of the walking assistant split 2. . The design of the wheelchair equipped with the auxiliary walking device is more scientific and the performance is better.

In addition, as shown in FIG. 1 and in conjunction with FIG. 10 , the wheelchair equipped with the auxiliary walking device is equipped with good basic conditions for the expansion of its functions. For example, the monitoring device 8 can be installed on the supporting part 205 of the walking aid 2, so as to realize remote monitoring of the user of the walking aid 2, such as location positioning, tipping alarm, video and audio information collection, etc. At the same time, a battery can be set on the wheelchair body 1. When the wheelchair is an electric wheelchair, the power battery of the wheelchair body 1 can be directly used; The power supply and charging of the monitoring device 8 and the line communication between the detection device on the wheelchair main body 1 and the monitoring device 8 can be realized.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the within the protection scope of the present invention.
