Counterweight structure for walking aid wheels

Abstract

This invention discloses a counterweight structure for a walking aid wheel, including a wheel cover; the wheel cover is mounted on the frame, and a wheel is mounted on the frame, with the wheel cover covering the wheel; the wheel cover has a counterweight structure for increasing the weight of the frame. This invention effectively lowers the frame's center of gravity by incorporating a counterweight structure on the wheel cover, reducing the risk of the vehicle tipping forward and improving safety performance. Simultaneously, the wheel cover, covering the wheel, makes the counterweight structure aesthetically pleasing, providing both wheel protection and decorative effect, and is applicable in a wide range of scenarios and is convenient to use.

Claims

1. A counterweight structure for a walking aid wheel, wherein: Includes wheel covers; wheel covers are mounted on the frame, on which wheels are mounted, and wheel covers are used to cover the wheels; the wheel covers are provided with a counterweight structure, which is used to increase the counterweight of the frame.

2. The counterweight structure for a walking aid wheel as described in claim 1, wherein: The counterweight structure is integrally formed with the wheel cover, and the counterweight structure forms the shape of the wheel cover, or the counterweight structure includes an independently set counterweight block, which is installed on the wheel cover.

3. The counterweight structure for a walking aid wheel as described in claim 2, wherein: The counterweight structure includes an independently set counterweight block, and a receiving cavity is provided inside the wheel cover. The counterweight block can be detachably installed in the receiving cavity.

4. The counterweight structure for a walking aid wheel as described in claim 3, wherein: The inner contour of the receiving cavity is consistent with the outer contour of the counterweight, allowing the counterweight to be embedded.

5. The counterweight structure for a walking aid wheel as described in claim 1, wherein: The wheel covers are detachably mounted on the vehicle frame.

6. The counterweight structure for a walking aid wheel as described in claim 5, wherein: The wheel covers are multiple in number, and the weights of the multiple wheel covers are different. One of the different wheel covers can be detachably installed on the frame.

7. The counterweight structure for a walking aid wheel as described in claim 5, wherein: The frame is provided with a mounting base, on which a slot is formed. The wheel cover is provided with a snap-fit ​​part that mates with the slot. It also includes a locking component that can switch between a locked state and an unlocked state. When the locking component is in the locked state, it can lock the snap-fit ​​part in the slot, so that the wheel cover is installed on the mounting base. The locking component includes a button for driving the locking component to switch to the unlocked state. When the locking component is in the unlocked state, the snap-fit ​​part can be inserted into or removed from the slot. After the snap-fit ​​part is removed from the slot, the wheel cover is removed from the mounting base.

8. The counterweight structure for a walking aid wheel as described in claim 7, wherein: The locking assembly further includes a limiting member and an elastic member; the limiting member is movably disposed in the slot, and after the engaging part is inserted into the slot, the limiting member can move closer to or away from the engaging part; the elastic member is connected to the limiting member and is used to elastically drive the limiting member to move laterally and approach the engaging part, abutting against the engaging part to lock the engaging part; the button is used to overcome the elastic force of the elastic member to drive the limiting member away from the engaging part, thereby unlocking the engaging part.

9. The counterweight structure for a walking aid wheel as described in claim 1, wherein: The wheel cover is installed on the frame of the walking aid. The walking aid has front wheels and rear wheels. After the wheel cover is installed, it covers the rear wheels of the walking aid. There are two rear wheels, and one wheel cover is installed for each rear wheel.

10. The counterweight structure for a walking aid wheel as described in claim 7, wherein: The mounting base is also equipped with a collision protection part, which protrudes from the front of the wheel.
