Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, be described in further detail detailed description of the invention of the present utility model, object helps those skilled in the art to have more complete, accurate and deep understanding to design of the present utility model, technical scheme, and contribute to its enforcement.
As shown in Figures 1 to 6, the utility model provides a kind of storage battery car rear-seat air protective device, comprises bracing frame 1, movable hand rail 2 and swinging gear 3; Bracing frame 1 is fixedly installed in the rear backrest 4 of storage battery car, and rear backrest 4 is positioned at the rear of back seat; Movable hand rail 2 is the rotatable left and right sides being arranged at storage battery car back seat; Swinging gear 3 is connected with bracing frame 1 and movable hand rail 2, and for making movable hand rail 2 in horizontality and vertically switching between state.
Specifically, as shown in Figure 1, the bracing frame 1 that rear backrest 4 is arranged not only can increase the scope of rear backrest 4, also plays the support of protective device and fixing.Be provided with movable hand rail 2 at the right and left of back seat, movable hand rail 2 can swing back and forth up and down, convenient for passenger to get on and off.Movable hand rail 2 structure adopts human oriented design, and uses Soft Roll, and children are taking in process, and use handrail can also play a supporting role to elbow, comfort level is very high.In addition, consider that back seat takes the difference of object, if adult, movable hand rail 2 can be holded up, without any impact, not only convenient but also safety.As shown in Figure 2, movable hand rail 2 comprises the handrail body of rod 13 and the handrail bar sleeve 14 be fixedly connected with the handrail body of rod 13 by bolt.
As shown in Figures 2 to 6, the movable end cover 15 that swinging gear 3 comprises the fixing end cap 5 be fixedly installed on bracing frame 1, be connected with fixing end cap 5 by center shaft 9, be fixedly installed on the ratchet 6 on fixing end cap 5 and be arranged at the ratchet 12 coordinated on the handrail body of rod 13 and with ratchet 6, ratchet 6 has at least two teeth groove allowing ratchet 12 embed, ratchet 12 coordinates with ratchet 6 and forms ratchet device, thus can realize movable hand rail 2 and switch between the two states.Fixing end cap 5 with movable end cover 15 for being oppositely arranged, center shaft 9 for being horizontally disposed with, the axis of center shaft 9 and the length direction of movable hand rail 2 perpendicular, movable end cover 15 can rotate relative to fixing end cap 5.The rear end of handrail bar sleeve 14 is fixedly connected with into a single integrated structure with movable end cover 15, and a part for the handrail body of rod 13 is between fixing end cap 5 and movable end cover 15, and the handrail body of rod 13 is also fixedly connected with the axle sleeve 16 be sheathed on center shaft 9.
As shown in Figures 2 and 3, fixing end cap 5 and movable end cover 15 are circular configuration, and ratchet 6 is arranged on the medial surface of fixing end cap 5, and ratchet 12 is arranged on the medial surface of the handrail body of rod 13.In the present embodiment, ratchet 6 has two teeth groove, is respectively the first teeth groove 17 and the second teeth groove 18; When ratchet 12 is in the first teeth groove 17 position, movable hand rail 2 is in vertical state; When ratchet 12 is in the second teeth groove 18 position, movable hand rail 2 is in horizontality.When movable hand rail 2 rotates, drive ratchet 12 synchronous axial system outside ratchet 6, ratchet 12 is rotationally connected by an axle and the handrail body of rod 13 at the medium position place of length direction, and the axis of this axle parallels with the axis of center shaft 9.
As shown in Figures 2 to 6, at corresponding first teeth groove 17 place, arrange one for the catch 10 spacing to ratchet 12, this catch 10 is connected with fixing end cap 5 by spring 19.Catch 10 and spring 19 are positioned at outside ratchet 6, and spring 19 one end is connected with fixing end cap 5, and the other end is connected with catch 10, and spring 19 is for applying to promote its application force towards first teeth groove 17 place's movement to catch 10.On fixing end cap 5, corresponding second teeth groove 18 place arranges one and embeds orienting lug 7 in the second teeth groove 18 for guiding ratchet 12, this orienting lug 7 is positioned at the outside of ratchet 6, and surface orienting lug 7 facing ratchet 6 is for contacting with ratchet 12 and guiding ratchet 12 to be rocked to can to embed the arc surface of the state in the second teeth groove 18.
As shown in Figure 4, when the movable hand rail 2 of the back seat left and right sides is turned to level attitude, in rotation process, play the effect of the ratchet 12 on the handrail body of rod 13 of stressed effect by orienting lug 7, embed in the second teeth groove 18 on ratchet 6, movable hand rail 2 rotates and puts in place.As shown in Figure 5, when back seat occupant gets off or not used time, upwards movable hand rail 2 to vertical position is rotated, the handrail body of rod 13 is also in vertical position, and so far, ratchet 12 under gravity, its front end can embed in the first teeth groove 17, thus can stop movable hand rail 2 forward downward swing automatically.Now catch 10 contacts with correcting after ratchet 12, and movable hand rail 2 can be stoped to be rotated further backward.When movable hand rail 2 again need be put down, as shown in Figure 6, the movable hand rail 2 of vertical state is continued slightly firmly to swing backward, offset the application force of spring 19 pairs of catch 10 applyings by the rear end of ratchet 12, in the process, the front end of ratchet 12 is because lever principle, can be upturned and deviate from from the first teeth groove 17, and cross ratchet because of the resistance of spring 19, now taking advantage of a situation rotates handrail again, will arrive level attitude smoothly.
As shown in Figures 4 to 6, the handrail body of rod 13 has a deep-slotted chip breaker 11 coaxial with center shaft 9, the end face of ratchet 6 is provided with the position-limited lever 8 in an embedding deep-slotted chip breaker 11, and the length direction of position-limited lever 8 parallels with the axis of center shaft 9, and position-limited lever 8 is set for the eccentric.Deep-slotted chip breaker 11 is set and position-limited lever 8 matches, is mainly used for playing control action to the amplitude of fluctuation of movable hand rail 2, avoids movable hand rail 2 hunting range excessive.
The storage battery car rear-seat air protective device of said structure has following advantage:
1, the safety problem when head of a family had considers that child takes back seat, back seat has been installed the child seat that has side shield, for larger children and adult, substantially can not use, also up and down inconvenient.Storage battery car rear-seat air protective device of the present utility model is just installed on original rear backrest 4 basis, and handrail can swing, and substantially do not change profile and the structure of back seat, function does not also affect.Not only can play protective action to during children's ride-on, also can not limit and take object, meet everyone demand.
2, storage battery car rear-seat air protective device of the present utility model, relates to a handrail swung.Handrail swing is realized by the application of ratchet device and lever principle, and rational in infrastructure, operation is very easy in use, and when taking, children can oneself operate.
In the ratchet device of 3, storage battery car rear-seat air protective device of the present utility model, conveniently during handrail activity downwards, ratchet 12 is separated with ratchet, innovative design employs a kind of lever ratchet 12, with the use of spring stop piece, by lever principle, realize the action that ratchet 12 is separated with ratchet 6 simply and easily.
Below by reference to the accompanying drawings the utility model is exemplarily described.Obviously, the utility model specific implementation is not subject to the restrictions described above.As long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; Or without improvement, above-mentioned design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model.
