It lies low in order to facilitate the elderly, disabled person, patient, wheelchair is designed to can lie low structure, such as Chinese Patent Application No. It discloses one kind for 201020548836.2 patent and can lie low electric wheelchair, including walking function module, foldable skeleton Partly, seat against part, auxiliary lie function module by the electric pushrod that lies low, push rod controller, connecting rod, right-handed thread joint Bearing, left hand thread oscillating bearing, foot pedal composition, chassis front end and leg support are hinged, rear end is then hinged with back rest, back rest It is connect by connecting rod between leg support, connecting rod two end installs right-handed thread oscillating bearing and left hand thread oscillating bearing respectively, puts down Electric pushrod seat end of lying is hinged on chassis, and rod end is then hinged in leg support, and a handrail is integrally fixed with chassis, Ling Yifu Hand is connect with chassis by folding controller.When the elderly, disabled person, patient need to lie low, it need to only turn to and lie low State, it is easy to use, but the existing Wheelchair structure that lies low is also more complicated, it is expensive.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and traditional horizontal lying-type Wheelchair structure complexity is of high cost High problem provides a kind of wheelchair having lie function.
In order to achieve the above object, technical solution used by the utility model is:
A kind of wheelchair having lie function,
Including wheelchair frame, the vehicle seat being set on the wheelchair frame and with the vehicle seat phase pivot mating backrest,
The wheelchair frame is equipped with the wheelchair armrest for being located at the vehicle seat both sides, is set up on the wheelchair armrest of both sides There is a position-limit mechanism for being limited to backrest, the provided at one of the position-limit mechanism is coupled on the wheelchair armrest of side, described The other end of position-limit mechanism is the mating end being detachably coupled on the wheelchair armrest of the other side,
The supporter that the wheelchair frame is located at the saddle base has for the outer support end for supporting backrest that lies low.
Preferably, the mating end of the position-limit mechanism has T-type bolt, with the mating end on matched wheelchair armrest Equipped with the T-type limiting slot room to match with the T-type bolt.
Preferably, the back side stage casing of the backrest is equipped with the groove of horizontal direction setting, and the position-limit mechanism is arched, described The arch central portion of position-limit mechanism and the groove match.
Preferably, the outer support end is equipped with the limit protrusion with the groove match.
Preferably, the section of the groove is in concave-curve.
Preferably, the wheelchair frame is additionally provided with the foot-operated of pivot mating.
Preferably, the wheelchair is electric wheelchair, and the wheelchair frame is equipped with the prestowage storage battery positioned at saddle base.
Preferably, the wheelchair is rear-guard formula electric wheelchair.
The beneficial effects of the utility model are mainly reflected in:
1. wheelchair, as support limit, is realized that sitting posture and lie function are realized, cut using position-limit mechanism and outer support end It changes convenient and reliable, easy to operate, simple for structure, of low cost.
2. using arch position-limit mechanism, stage casing protrusion is as limiting section, and both sides are as gripping handrail, clever structure.
3. outer support end can be used for placing article in sitting posture, has storage function.
Description of the drawings
Fig. 1 is a kind of sitting posture structural schematic diagram for the wheelchair having lie function of the utility model.
Fig. 2 is a kind of structural schematic diagram that lies low for the wheelchair having lie function of the utility model.
Fig. 3 is a kind of overlooking structure diagram for the wheelchair having lie function of the utility model.
Specific implementation mode
The utility model provides a kind of wheelchair having lie function.Below in conjunction with attached drawing to technical solutions of the utility model It is described in detail, so that it is more readily understood and grasps.
A kind of wheelchair having lie function as depicted in figs. 1 and 2, including wheelchair frame 1, is set on wheelchair frame 1 Vehicle seat 2 and backrest 3 with the mating of 2 phase pivot of vehicle seat, wheelchair frame 1, which is equipped with, is located at the wheelchair armrests of 2 both sides of vehicle seat 4, a position-limit mechanism 5 for limit to backrest 3 is provided on the wheelchair armrest 4 of both sides, the provided at one of position-limit mechanism 5 is coupled In on the wheelchair armrest of side, the other end of position-limit mechanism 5 is the mating end being detachably coupled on the wheelchair armrest of the other side, wheelchair The supporter that vehicle frame 1 is located at 2 bottom of vehicle seat has for the outer support end 7 for supporting backrest 3 that lies low.
Specifically realize process and principle:
Wheelchair sitting posture state, as shown in Figure 1, backrest 3 is in vertical, vehicle seat 2 is in seat shape, 5 frame of position-limit mechanism with backrest 3 Between the wheelchair armrest 4 of both sides, the back side of backrest 3 is by 5 support limit of position-limit mechanism.
Wheelchair lying status first moves backrest 3 towards vehicle seat 2, and backrest 3 is made to be separated with 5 phase of position-limit mechanism, at this time will Mating end and the wheelchair armrest of position-limit mechanism 5 are separated, and pivot is overturn to vertical state, are not desired to interfere with backrest 3, then will Backrest 3 is moved towards outer support end 7, and backrest 3 is abutted against with outer support end 7, as shown in Fig. 2, backrest 3 is horizontal, After user lies low, position-limit mechanism 5 can be resetted, as safeguard protection.
Refinement description is carried out to the detachable mechanism of position-limit mechanism, mating end has T-type bolt 6, matches with mating end The wheelchair armrest connect is equipped with the T-type limiting slot room 8 to match with T-type bolt 6.When T-type bolt 6 is embedded in T-type limiting slot room 8 When, wheelchair armrest can limit position-limit mechanism.Its principle is limited by the own wt of position-limit mechanism, is not necessarily to Other lockable mechanisms carry out locking.
In preferred embodiment, the back side stage casing of backrest 3 is equipped with the groove 9 of horizontal direction setting, as shown in figure 3, position-limit mechanism 5 Arched, arch central portion and the groove 9 of position-limit mechanism match.Arch both sides, which are formed, holds handrail, is pushed away convenient for holding It is dynamic.Limited support is reliable simultaneously.
In addition, outer support end 7 is equipped with the limit protrusion 10 to match with groove 9.The limit protrusion 10 also be used for pair Backrest 3 is limited, and the stability for the structure that lies low is increased.
It should be noted that the section of the groove 9 is in concave-curve.Arc mating has certain mating tolerance, also can be real Now certain offset correction.
Wheelchair frame 1 in this case is additionally provided with foot-operated the 11 of pivot mating.Foot-operated 11 level having when lying low is fixed Heeling condition when state and sitting posture.Foot-operated 11 adjusting fixation belongs to the prior art, and details are not described herein.
Finally, the wheelchair of this case is electric wheelchair, and wheelchair frame 1 is equipped with the prestowage storage battery 12 positioned at saddle base.Wheel Chair is rear-guard formula electric wheelchair.Electric wheelchair has certain weight, and lying status is more stable.The center of gravity of rear-guard formula electric wheelchair Be more conducive to lie low the stability of wheelchair.
By above description it can be found that a kind of wheelchair having lie function of the utility model, using position-limit mechanism and Outer support end realizes that sitting posture and lie function are realized as support limit, easy switching is reliable, it is easy to operate, simple for structure, It is of low cost.Using arch position-limit mechanism, stage casing protrusion is as limiting section, and both sides are as gripping handrail, clever structure.Outer branch Support end can be used for placing article in sitting posture, have storage function.
