Abstract
Description
Technical Field
[0001] The utility model relates to a shock absorber structure, especially a shock absorber structure with novel structure and cost-saving manufacturing cost.
Background Art
[0002] A wheelchair is an assistive device for the physically uncomfortable to move around. Installing a shock absorber on the wheelchair can make the wheelchair rider more comfortable. In existing patented cases of wheelchairs equipped with shock absorbers, such as the patent case of "Shock Absorber and Wheelchair Caster with Shock Absorber" with Taiwan, China certificate number M520368, the shock absorber is installed on the caster at the front end of the wheelchair. In application, since the main riding center of gravity of the rider is at the rear wheel, installing the shock absorber on the caster results in poor shock absorption effect. In addition, for the patent cases of "Wheelchair Structure" with Taiwan, China patent certificate number M271566 and "Wheelchair" with publication number 530649, although the shock absorber is installed on the rear wheel, the existing shock absorber structure has many components, complex structure and high cost. Obviously, the above problems need to be improved.

Detailed Description of the Invention
[0023] Please refer to Figure 1 、 2As shown in the figure, the shock absorber 1 of the preferred embodiment of the present utility model is installed on an object 2 with shock absorption requirements (such as a wheelchair or a bicycle seat cushion, etc.). The shock absorber 1 is surrounded by a rigid and elastic flat body 10, and the flat body 10 can be made of a composite material (carbon fiber material). The interior of the flat body 10 after surrounding is hollow, and it is composed of two corresponding long axis sides 11, 12 and two short axis sides 13, 14. In the middle section of the top end of one of the two long axis sides 11, there is a protruding seat 110 protruding upward. The protruding seat 110 is provided with fixing holes 111 (two can be provided front and back), and bolts 23 pass through the fixing holes 111 to be fixed to the fixed end 22 of the object (such as the frame of a wheelchair). In the middle section of the bottom end of the other long axis side 12, there is a connection hole 120, and the connection hole 120 is used for connecting the movable end 21 of the object 2 (such as the wheel axle of the rear wheel of a wheelchair). The two short axis sides 13, 14 are configured with rounded corners 130, 140. Because the interior of the flat body 10 after surrounding is hollow, and the two short axis sides 13, 14 are provided with rounded corners 130, 140, there is buffering between the two long axis sides 11, 12.
[0024] When the above shock absorber 1 is fixed to an object 2 (such as a wheelchair), that is, as Figure 1 shown, during installation, it can be like Figure 3 shown, on both the left and right sides of the fixed end 22 of the object 2 (wheelchair) (such as the frame of the wheelchair) corresponding to the setting position of each movable end 21 (such as the wheel axle of the rear wheel 20 of the wheelchair), one shock absorber 1 of the present utility model is used. When the object 2 (such as a wheelchair) travels on a rough road surface, the movable end 21 (such as the wheel axle of the rear wheel 20 of the wheelchair) will be subjected to an upward stress and squeeze the long axis side 12 of the shock absorber 1 to deform upward (as Figure 4 ), so that the movable end 21 (rear wheel 20) can be buffered, and if the wheelchair rider passes through a rough road surface, the stability and comfort can still be maintained. With the setting of the present utility model, the wheelchair has a shock absorption effect, and the shock absorber is fast in production and cost-saving.
[0025] Similarly, the shock absorber 1 of the embodiment of the present utility model can also be applied to the seat cushion of a bicycle, that is, the movable end 21 of the shock absorber 1 of the present utility model is connected to the seat post of the seat cushion, and the fixed end 22 is connected to the seat tube of the bicycle frame, and it can also achieve the effect that the seat cushion has a shock absorption effect when the bicycle is traveling on an uneven road surface, so that the rider has a buffering comfort when riding.
