Abstract

The invention provides a light two-wheel balance vehicle for children. The vehicle comprises a motor wheel, a left pedal, a right pedal, a battery and a controller. The left pedal and the right pedal each comprise an upper cover and a bearing lower cover. The motor wheels are connected with the bearing lower covers through fixing parts installed in fixing piece grooves. Reinforcing ribs which are crossed in a warp-weft mode are arranged in one end of each bearing lower cover. Shaft grooves are formed in the middles of the reinforcing ribs. The left pedal and the right pedal are connected through a connecting shaft installed in the shaft grooves and achieve relative rotation. According to the light two-wheel balance vehicle, no metal framework is needed; by reasonably arranging the reinforcing ribs and changing the connecting shaft structure, on the basis of ensuring the strength of the pedals, the vehicle body weight is reduced, and portability and user experience are improved. Due to the fact that no metal framework is needed, no mold manufacturing or frame casting technological process for a metal framework is needed, and the product production cost is reduced. The weight of the two-wheel balance vehicle is 3-4 kg, and the two-wheel balance vehicle is suitable for children with the weight smaller than 50 kg.

Detailed description of the invention

For a better understanding of the present invention, illustrate below in conjunction with drawings and Examples.

Embodiment: as depicted in figs. 1 and 2, a kind of children's money lightweight two-wheel balance truck, comprise symmetrically arranged left-hand tread plate and right-hand tread plate, left and right pedal includes load-bearing lower cover 3 and is fastened on the upper cover 2 on load-bearing lower cover 3, upper cover 2 and load-bearing lower cover 3 all have engineering plastics to make, and quality is solid and quality is light.Motor wheel 1 is arranged at left and right pedal two ends and is fixed in load-bearing lower cover 3, for motor wheel 1 wheel shaft 11 realizing metal material is firmly connected with the load-bearing lower cover 3 of plastic material, described motor wheel 1 wheel shaft 11 is provided with wheel shaft fixed block 12, wheel shaft fixed block 12 is provided with four tapped bore.Load-bearing lower cover comprises wheel shaft district, battery area and adapter shaft district by one end of motor wheel successively to one end of adapter shaft.Wheel shaft district by two vertical pedal shafts to reinforced rib form, the reinforced rib of other two horizontal directions forms with it the connecting element groove 31 of mounting fixing parts 4.Described connecting element 4 is provided with axle hole 41, and axle hole 41 surrounding is provided with four transverse holes 42, connecting element 4 is also provided with two vertical holes 43.When mounted motor takes turns 1, wheel shaft 11 fixed block and connecting element 4 are fixedly secured by screw, then connecting element 4 is arranged in connecting element groove 31, being fixed by screws in by vertical hole 43 afterwards weighs in lower cover, the setting of connecting element 4 and connecting element groove 31 achieves effectively being fastenedly connected of metal material wheel shaft 11 and plastic material lower cover, the propulsive effort of effective dispersion motor wheel 1 and human bady gravitational, reduce local stress.

For realizing the connection of left and right pedal and relatively rotating, in described load-bearing lower cover 3, adapter shaft 5 is installed.Larger twisting resistance is born at the position that load-bearing lower cover 3 carries turning cylinder, for strengthening lower cover intensity, is provided with the some reinforced ribs in longitude and latitude cross arrangement in described lower cover, and reinforced rib upper surface is provided with the arc placing adapter shaft 5 and connects axial trough 33.Described adapter shaft 5 arranged on left and right sides is respectively provided with two circular grooves, is provided with the axle collar 6, is provided with bearing 7 in right circular groove in the circular groove of left side.Adapter shaft 5 and the axle collar 6 all adopt the aluminum alloy that quality is light, intensity is large to make.The described axle collar 6 inwall and the axle collar 6 outer wall are provided with protruding twisting key 61, and described adapter shaft 5 outer wall is also provided with the keyway 51 matched with the twisting key 61 of the axle collar 6 inwall.As shown in Figure 3 and Figure 4, adapter shaft 5 is fit in load-bearing lower cover 3, and the axle collar 6 and bearing 7 are reinforced muscle and fix, cannot sway, and the twisting key 61 of the axle collar 6 outer wall cannot rotate by the constraint of the two pieces of reinforced ribs in front and back, thus fixedly secures in load-bearing lower cover 3.The twisting key 61 of the axle collar 6 inwall is fastened in the keyway 51 of adapter shaft 5, adapter shaft 5 cannot be rotated in left-hand tread plate, reinforced rib support adapter shaft 5 in adapter shaft mounting groove also makes it cannot sway, thus achieve adapter shaft 5 fixedly securing in pedal, and the rotation of left and right pedal is because there is the existence of bearing 7, friction force is little, rotates smooth.The side end that described adapter shaft 5 is provided with bearing 7 is provided with arc notch 52, described load-bearing lower cover 3 is positioned at arc notch 52 place and is provided with back-up block 34, stopped by back-up block 34 after axis of rotation certain angle and can not be rotated further, effectively prevent because two pedal rotational angles are excessive, make balance truck lack of equilibrium, prevent danger.Battery 8 and controller 9 are arranged in the battery case 32 between adapter shaft mounting groove and connecting element mounting groove, rationally arrange in space, reduce car body volume, and battery 8 also plays the effect of dispersion human bady gravitational in addition.Screw mounting hole surrounding in load-bearing lower casing is provided with reinforced rib, ensures screw fastening intensity.

Metal framework is provided with in the left and right pedal of two-wheeled balance truck (turning round car) of the prior art, arranged on left and right sides framework is connected by the adapter shaft 5 be arranged in sleeve, and realize relatively rotating, metal framework not only makes product weight greatly increase, and the moulding of restriction car body.Two-wheeled balance truck described in the present embodiment, without the need to metal framework, by the reasonable Arrangement of reinforced rib and the change of adapter shaft 5 structure, on the basis ensureing pedal load-bearing, alleviates car body weight, adds portability and the experience of two-wheel balance truck.Its profile is arranged not by the restriction of metal framework, provides more Creative spaces for pedal is moulded.There is no metal framework, just do not need Making mold and the framework foundry technology process of metal framework, reduce production finished product, shorten the production cycle.Through strength test find, this two-wheel balance truck can below safe bearing load 70kg people use and there are not quality problems, therefore its consumer group is set as 50kg and following children, and whole balance truck weight is 3-4kg, and quality greatly alleviates.

In order to increase the safety that balance truck uses, described load-bearing lower cover 3 side is provided with steering indicating light 35, and outer fastening of steering indicating light 35 has lampshade 36, and upper cover 2 place of trampling is provided with the rubber pad 21 being with anti-skidding striped, increases friction force.

The above; it is only preferred embodiment of the present invention; it is not restriction the present invention being made to other form; the Equivalent embodiments that any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as equivalent variations is applied to other field; but everyly do not depart from technical solution of the present invention content; according to any simple modification, equivalent variations and remodeling that technical spirit of the present invention is done above embodiment, still belong to the protection domain of technical solution of the present invention.
