[0018] The utility model is described in detail below with reference to the accompanying drawings. Figures 1 to 3 shown.

[0019] Example 1: See Figure 1 , Figure 2 A walking auxiliary anti-rollover mechanism, which includes a bracket 8, the two ends of the rear side of the bracket 8 are respectively connected to rollers 2, the middle part of the front side of the bracket 8 is connected to a universal wheel 1, at least one of the two ends of the rear side of the bracket 8 is connected to a rear extension block 6, and the rear extension block 6 is connected to an auxiliary support unit, the lowermost end of the auxiliary support unit is higher than the lowermost end of the roller 2, see Figure 1 .

[0020] When the auxiliary intelligent bracket is installing a push machine or walking, if an accident occurs and causes the front end of the bracket 8 to be lifted upward, and the entire bracket 8 flips around the two rollers 2 at the rear end, the rear end of the bracket 8 flips toward the ground. Since at least one of the two ends of the rear side of the bracket 8 is connected to the rear extension block 6, and the extension block is connected to the auxiliary support unit, the auxiliary support unit will touch the ground first; and together with the rollers 2 on both sides of the rear end of the bracket 8, the auxiliary intelligent bracket is supported. At this time, the auxiliary support unit and the two rollers 2 support the auxiliary intelligent bracket, which is a 3-point or 4-point support, so that the auxiliary intelligent bracket maintains balance and avoids flipping over to the ground; then it can be straightened with manual assistance.

[0021] See also Figure 2 , Figure 3 Both ends of the rear end of the bracket 8 are respectively connected to the rear extension block 6.

[0022] Rear extension blocks 6 are respectively arranged on both sides of the rear end of the bracket 8, and the rear extension blocks 6 are connected to auxiliary support units. When flipped backwards, the two auxiliary support units will support the auxiliary intelligent bracket and the hand-push machine together with the two rollers 2. The four-point support is more stable than the three-point support; especially when the auxiliary support unit is closer to the corresponding front roller 2.

[0023] The roller 2 is connected to a driving motor, and the driving motor is arranged inside the roller 2 .

[0024] The auxiliary intelligent support needs to turn during walking, etc. When turning, the rotation speed of the rollers 2 on both sides is controlled to be different, so that the turn can be made. In order to prevent the driving motor from being affected by the outside world, the driving motor is set inside the roller 2, and the connecting shaft of the roller 2 is connected to the support 8.

[0025] Furthermore, the auxiliary supporting unit is an auxiliary supporting wheel 3 .

[0026] After the auxiliary support unit is provided with auxiliary support wheels 3, when the whole unit is unstable and flips over, the auxiliary support wheels 3 contact the ground, and due to inertia, the auxiliary support wheels 3 and the rollers 2 will move backwards for a short distance. The friction between the auxiliary support wheels 3, the rollers 2 and the ground is rolling friction, thereby reducing the friction coefficient with the ground and avoiding damage to the ground, especially the carpet.

[0027] Furthermore, the rear extension block 6 is arranged in an L shape, and the auxiliary support wheel 3 is located directly behind the roller 2 .

[0028] The rear extension block 6 is set to be L-shaped, so that the rear end width of the rear extension block 6 is larger and can be sufficient to connect the auxiliary support wheel 3; secondly, the auxiliary support wheel 3 is set directly behind the roller 2, so that the auxiliary support wheel 3 does not occupy the internal space, which is beneficial to space distribution.

[0029] Preferably, the rear extension block 6 is provided with a plurality of main connection holes 7 arranged at intervals in rows, and the bracket 8 is provided with secondary connection holes arranged corresponding to the main connection holes 7. The rear extension block 6 is connected to the bracket 8 through a connecting piece passing through the main connection holes 7 and the secondary connection holes.

[0030] A plurality of rows of main connection holes 7 are arranged on the rear extension block 6. When connecting, one row of the connection holes can be selected to be connected to the bracket 8; thereby, the use length of the rear extension block 6 can be adjusted as needed; the auxiliary intelligent bracket has different center of gravity offsets after being connected to different hand-push machines; and in the event of an unexpected situation, the degree to which the auxiliary intelligent bracket tilts backwards is also different; the rear extension block 6 of appropriate length can be selected according to the different hand-push machines.

[0031] Furthermore, the auxiliary support wheel 3 is connected to a connecting seat 4 , the connecting seat 4 is connected to the rear end of the rear extension block 6 , and a flexible buffer block 5 is provided between the connecting seat 4 and the rear end of the rear extension block 6 .

[0032] After the flexible buffer block 5 is provided, when the auxiliary support wheel 3 contacts the ground, the flexible buffer block 5 is used for buffering, thereby reducing the impact force. The flexible buffer block 5 can be a rubber block or the like.

[0033] An auxiliary intelligent support comprises the above-mentioned walking auxiliary anti-tipping mechanism and also comprises a control mechanism for controlling the walking of rollers.

[0034] The above contents are only preferred embodiments of the utility model. For ordinary technicians in this field, according to the concept of the utility model, there will be changes in the specific implementation method and application scope. The content of this specification should not be understood as a limitation on the utility model.
