Fig. 5 shows a schematic structural view of a walking aid according to another exemplary embodiment of the present invention, and fig. 6 shows a schematic wheel arrangement of a walking aid according to another exemplary embodiment of the present invention.

The walking aid and wheel arrangement shown in fig. 5 and 6 is substantially the same as the one shown in fig. 1 and 4, except that it further comprises two third universal wheels 5208 arranged in the middle of the frame. The two rectilinear wheels 1206 are respectively arranged at the outer sides of the two third universal wheels 5208, and the electric brake 3100 is respectively matched with the two rectilinear wheels 1206.

In this embodiment, by adding two third gimbals 5208, support can be added, preventing both electric brakes 3100 from taking up excessive pressure.

According to some embodiments, referring to fig. 5 and 6, two third universal wheels 5208 are disposed between two electric brakes 3100 and in-line with the two electric brakes 3100.

According to some embodiments, referring to fig. 6, the two third universal wheels 5208 form two rectangles with the two first universal wheels 1202 and the two second universal wheels 1204, respectively. This arrangement maximizes the space available to the user while increasing support and stability.

According to the embodiment shown in fig. 5 and 6, the stability and safety of the walking aid can be improved by arranging at least three groups of six wheels and arranging the directional braking wheels between two groups of universal wheels, and preventing the walking aid from irregularly moving by combining the directional wheels and the universal wheels. In addition, stability and safety during the preparation can be further improved. The walking aid according to this embodiment may give the user a higher safety and a more reassuring psychological expectation.

Fig. 7A shows a block schematic diagram of a control device according to an embodiment of the present invention.

Referring to fig. 7A, a control device 7000 according to an embodiment of the present invention includes a pressure trigger 1118 and a transmission control module 7100. The transmission control module 7100 may be electrically connected to the electric brake 3100.

As previously described, the transmission control module 7100 may transmit an electrical signal to the electric brake 3100 to control the directional electric brake wheel to brake off when the pressure trigger 1118 is pressure triggered.

When the pressure trigger 1118 is reset, the transmission control module 7100 interrupts the transmission of electrical signals to the electric brake 3100 to direct the electric brake wheel to resume braking.

According to some embodiments, the control device 7000 may also comprise an emergency braking module 7200 for braking the electric brake 3100 in case of an emergency. For example, emergency braking module 7200 may implement emergency braking by immediately disconnecting the path that transmits electrical signals to electric brake 3100.

Fig. 7B shows a block schematic diagram of a control device according to another embodiment of the present invention.

Referring to fig. 7B, the control device 7000 according to the embodiment of the present invention includes a pressure trigger 1118, a transmission control module 7100, and a delay module 7300. The transmission control module 7100 may be electrically connected to the electric brake 3100. The delay module 7300 performs a delay operation according to the electrical signal of the pressure trigger 1118.

When the pressure trigger 1118 is pressure activated, the transmission control module 7100 may transmit an electrical signal to the electric brake 3100 to control the directional electric brake wheel to release the brake after a delay period by the delay module 7300. The delay module 7300 may be, for example, a delay switch circuit.

When the pressure trigger 1118 is reset, after a delay period of time has elapsed from the time delay module 7300, the transmission control module 7100 interrupts the transmission of electrical signals to the electric brake 3100 to direct the electric brake wheel to resume braking.

In this embodiment, due to the use of the time delay module 7300, the user can be prevented from falling down when the walking aid is suddenly started or stopped, further improving the safety.

To avoid the delay function in case of an emergency, the emergency braking module 7200 described above may be provided.

Fig. 7C shows a block schematic diagram of a control device according to another embodiment of the present invention.

Referring to fig. 7C, a control device 7000 according to another embodiment of the present invention includes pressure trigger devices 1118A and 1118B, a transmission control module 7100, and a selection module 7400. The transmission control module 7100 may be electrically connected to the electric brake 3100.

The selection module 7400 may be used to set the pressure trigger 1118A or 1118B active. The selection module 7400 may include a left-right hand selection switch 2106 as before.

If pressure trigger device 1118A is selected via selection module 7400, transmission control module 7100 can transmit an electrical signal to electric brake 3100 to control the directional electric brake wheel to brake off when pressure trigger device 1118A is pressure triggered. The pressure trigger 1118B is inactive.

If pressure trigger device 1118B is selected via selection module 7400, transmission control module 7100 can transmit an electrical signal to electric brake 3100 to control directional electric brake wheel de-braking when pressure trigger device 1118B is pressure triggered. The pressure trigger 1118A is inactive.

In this embodiment, a delay block 7300 may also be provided.

Fig. 7D shows a block schematic diagram of a control device according to another embodiment of the present invention.

Referring to fig. 7D, a control device 7000 according to an embodiment of the present invention includes pressure trigger devices 1118A and 1118B, a transmission control module 7100, and a determination module 7500. The transmission control module 7100 may be electrically connected to the electric brake 3100.

The determination module 7500 can determine that the trigger is valid when either or both of the first and second pressure trigger devices are pressure triggered. When the pressure trigger device is reset, the opposite is true.

For example, the determination module 7500 may control a path of the electrical signal transmitted to the electric brake 3100 using a series or parallel circuit, but the present invention is not limited thereto.

When the user triggers the pressure trigger device, the directional electric braking wheel releases the brake, and the walking aid can walk. Therefore, the problems of limited grip strength and slow response of the hands of the patient are solved. In addition, aiming at the problem that the patient easily moves to form danger when standing up and sitting, the device not only solves the problem that the accompanying person forgets to lock the wheels when assisting the patient to go up and down, but also is convenient for the patient to sit and stand by himself and freely control the walking.

According to some embodiments, by providing at least three sets of six wheels and a directional braking wheel between two sets of universal wheels, the stability and safety of the walker may be improved by the combination of directional wheels and universal wheels.

According to some embodiments, an emergency button is provided. When the pressure trigger device fails or other emergency braking situations are needed, emergency braking can be carried out through the emergency button.

According to some embodiments, the two groups of universal wheels and the two directional electric braking wheels are arranged on the same circumference, so that the wheels have larger supporting areas on the whole, and the stability and the safety of the system are improved.
