Abstract
The invention discloses an electric wheelchair shock-proof structure, which comprises a shock-proof spring A and a shock-proof spring B, wherein the shock-proof spring A and the shock-proof spring B are respectively arranged on the rear side of an electric wheelchair, and are arranged in a symmetrical structure, are responsible for energy absorption, and form 30 degrees-70 degrees angles with the ground, one end of the shock-proof spring A and the shock-proof spring B is arranged on the upper end of a front main frame, and the other ends of the shock-proof spring A and the shock-proof spring B are connected with a motor frame anti-fall wheel pipe. The electric wheelchair shock-proof structure achieves steady operation in turning and bad conditions, and furthest reduces and eliminates vibration and discomfort.
Description
Technical field
The present invention relates to electric wheelchair field, particularly relate to a kind of electric wheelchair anti-vibration structure.
Background technology
In the technical field of old articles for use and rehabilitation material class, electric wheelchair is widely used, at present, all kinds of electric wheelchair body frame structure for automotive, does not have suspension system, meets jolt road surface or adverse circumstances, drive sensation and comfort level poor, impact strong degree is crossed conference and is brought insecurity.Especially, for suffering from cardiovascular and cerebrovascular vessel, old man's rehabilitation of cerebral thrombosis brings certain risk, for this reason, the invention provides a kind of electric wheelchair anti-vibration structure, better assimilation effect can be had to vibrational energy, turn at electric wheelchair and under severe environmental conditions, achieve the even running of electric wheelchair.
Summary of the invention
The invention provides a kind of electric wheelchair anti-vibration structure, adopt shock absorber spring, be arranged on position of centre of gravity on rear side of electric wheelchair, electric wheelchair is run steadily mobile, the present invention, not only for the electric wheelchair compared with large-scale vechicle, also can be used for the portable electric wheelchair of less vehicle.
Described a kind of electric wheelchair anti-vibration structure, comprise shock-proof spring A, shock-proof spring B, shock-proof spring A, shock-proof spring B, be separately positioned on rear side of electric wheelchair, shock-proof spring A and shock-proof spring B is symmetrical structure, be responsible for energy absorption, two springs become 30 degree-70 to spend angle with ground simultaneously, described spring A, spring B, one end is arranged on front main car frame upper end, the other end connects that motor rack is anti-down takes turns pipe, two springs become 5-30 degree angle with the anti-down pipe of taking turns of electric wheelchair motor rack simultaneously, described shock-proof spring A, shock-proof spring B, adopt spirillum, spring adopts and rotates coiling, the number of turns is between 12-18 circle, shock-proof spring A, shock-proof spring B internal diameter is between 25 millimeters to 50 millimeters, simultaneously at shock-proof spring A, shock-proof spring B two is provided with hook structure.
A kind of optimal technical scheme, described shock-proof spring A, shock-proof spring B surface is provided with one deck protection enamelled coating, improves anticorrosion antirust ability.
Further, a kind of optimal technical scheme, in order to improve the safety coefficient of spring, at shock-proof spring A, shock-proof spring B is provided with sleeve outward respectively.
Described shock-proof spring A, shock-proof spring B, the principle alleviating vibration is:
Described electric wheelchair motor mechanical axis is connected to power wheel, motor wheels runs, enter uneven road surface, produce the energy of pitch, when vibration energy is passed to main car frame, because motor rack one and vehicle frame are dynamically connected, supported by shock-proof spring, first energy is absorbed by shock-proof spring, very little when vibration energy is delivered to main car frame, left and right two part anti-vibration structures become mutual mirror image, main car frame is due to the absorption of front and back two shock-proof spring energy, vehicle frame is more steady in the process of moving, jolting, the performance of the shock-proof effect on road surface is particularly protruded, make the driving of electric wheelchair driver steadily comfortable.
The invention has the beneficial effects as follows: a kind of electric wheelchair anti-vibration structure of the present invention, makes electric wheelchair under turning and mal-condition, realize even running, farthest reduce and eliminate vibrations and sense of discomfort, farthest ensures the safety in driving process.
Accompanying drawing explanation
Fig. 1 is the perspective view of the electric wheelchair at electric wheelchair anti-vibration structure place of the present invention;
Fig. 2 is the structure chart of a kind of electric wheelchair anti-vibration structure of the present invention;
Fig. 3 is a kind of electric wheelchair anti-vibration structure of the present invention enlarged drawing;
In accompanying drawing, the labelling of each parts is as follows:
1 is shock-proof spring A, and 2 is shock-proof spring B, and 3 is front main car frame, and 4 take turns pipe for motor rack is anti-down.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 to Fig. 3, the embodiment of the present invention comprises:
Described a kind of electric wheelchair anti-vibration structure, comprise shock-proof spring A, shock-proof spring B, shock-proof spring A, shock-proof spring B, be separately positioned on rear side of electric wheelchair, shock-proof spring A and shock-proof spring B is symmetrical structure, be responsible for energy absorption, two springs become 30 degree-70 to spend angle with ground simultaneously, described spring A, spring B, one end is arranged on front main car frame upper end, the other end connects that motor rack is anti-down takes turns pipe, two springs become 5-30 degree angle with the anti-down pipe of taking turns of electric wheelchair motor rack simultaneously, described shock-proof spring A, shock-proof spring B, adopt spirillum, spring adopts and rotates coiling, the number of turns is between 12-18 circle, spring A, spring B internal diameter is between 25 millimeters to 50 millimeters, simultaneously at shock-proof spring A, shock-proof spring B two is provided with hook structure.
A kind of optimal technical scheme, described spring A, spring B surface is provided with one deck protection enamelled coating, improves anticorrosion antirust ability.
Further, a kind of optimal technical scheme, in order to improve the safety coefficient of spring, at shock-proof spring A, shock-proof spring B is provided with sleeve outward respectively.
Described shock-proof spring A, shock-proof spring B, the principle alleviating vibration is:
Described electric wheelchair motor mechanical axis is connected to power wheel, motor wheels runs, enter uneven road surface, produce the energy of pitch, when vibration energy is passed to main car frame, because motor rack one and vehicle frame are dynamically connected, supported by shock-proof spring, first energy is absorbed by shock-proof spring, very little when vibration energy is delivered to main car frame, left and right two part anti-vibration structures become mutual mirror image, main car frame is due to the absorption of front and back two shock-proof spring energy, vehicle frame is more steady in the process of moving, jolting, the performance of the shock-proof effect on road surface is particularly protruded, make the driving of electric wheelchair driver steadily comfortable.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
