Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further illustrated.
As shown in Figure 1 and Figure 4, travelling aided bicycle of the present utility model comprises foldable carriage, bottom of frame is provided with wheel, vehicle frame top is provided with handle, it is characterized in that: described wheel 10 is arranged on vehicle frame by bolt and nut, wheel central authorities install through hole along axletree to being provided with wheel, nut comprises nut connecting portion 103 and nut catch 104, nut catch 104 is positioned at wheel and installs through hole outside, nut connecting portion 103 is positioned at wheel and installs through hole inside, bolt comprises bolted connection 101 and bolt catch 102, bolt catch 102 is positioned at wheel and installs through hole outside, bolted connection 101 is positioned at wheel and installs through hole inside and be threaded with nut connecting portion 103.Traditional connected mode is that nut is set directly at wheel outside, makes like this to there is multiple nut between two adjacent travelling aided bicycles, needs to take larger space.And said structure of the present utility model, because relevant connection is positioned at inside wheel, and outside only needs corresponding catch, and catch to make very thin structure.Therefore the occupation of land space of travelling aided bicycle can be saved.Be folding in conjunction with vehicle frame simultaneously, travelling aided bicycle volume after folding therefore can be made very little.One time freight volume can correspondingly increase, thus can reduce cost of transportation.
The embodiment of above-mentioned foldable chassis has multiple.Here a kind of structure is introduced simple, convenient folding, be conducive to joint space-efficient foldable carriage.As shown in Figure 1 to Figure 3, described vehicle frame comprises side arm and after-frame, side arm comprises two forelegs 12, after-frame comprises and described two forelegs 12 two back legs 9 one to one, described back leg 9 is arranged on the outside of corresponding foreleg 12, after-frame also comprises the transverse tube 8 connected between two back legs, transverse tube 8 is the horizontal expansions along vehicle frame, the namely direction of arrow in Fig. 1, connector 11 is hinged with between the back leg 9 that described foreleg 12 is corresponding with it, side arm is also provided with for carrying out spacing block mechanism to described transverse tube, block mechanism comprises stop support 19 and by block back shaft and the hinged block 18 of stop support 19, block back shaft is provided with block reduction torsion spring.Fig. 1 and Fig. 2 is the state diagram after vehicle frame launches.Now, transverse tube 8 is positioned at the below of block 18, and block 18 is pressed in the surface of transverse tube 18 under the effect of block reduction torsion spring, makes transverse tube 8 to move up like this, and vehicle frame is in deployed condition and cannot folds.When needs are folding, withdrawn by block 18 by external force, block 18 is separated with transverse tube 8, and transverse tube 8 can move up, and transverse tube 8 moves up and back leg 9 lower end can be driven to move towards foreleg 12, and connector 11 is also taken advantage of a situation rotation.When needs launch vehicle frame again, transverse tube 8 can be pressed down, the lower end of back leg 9 can away from foreleg 12, after being depressed into certain position, transverse tube 8 is resisted against foreleg 12, as shown in Figure 1, then by external force, block 18 is toggled it to the top of transverse tube 8, block 18 is because the effect meeting automatic impaction of block reduction torsion spring is on the surface of transverse tube 8, thus the movement of restriction transverse tube 8.During design, it is circular pipe that transverse tube 8 is preferably cross section, and one end that block 18 contacts with transverse tube 8 is arc, can be convenient to top block 18 being moved to transverse tube 8 by external force like this.
The mounting means of above-mentioned wheel and vehicle frame has multiple.For the ease of producing and assembling, described wheel 10 is connected with vehicle frame by wheel mounting bracket, wheel mounting bracket comprises wheel mounting portion and Straight connecting portion 14, and vehicle frame offers arc groove, in the arc groove that Straight connecting portion 14 embeds on vehicle frame and and Frame Welding.Because traditional wheel 10 is also be connected with vehicle frame by wheel mounting bracket, and in traditional connected mode, Straight connecting portion 14 generally needs extra support chip together with Frame Welding.But this utility model, owing to directly opening an arc groove in vehicle frame relevant position, can save the auxiliary support structures such as support chip like this.
Place can be had when feeling tired out for the convenience of the users to sit down have a rest, described vehicle frame is provided with seat board.User can be sitting on seat board and have a rest.
Conveniently belongings, above-mentioned travelling aided bicycle also comprises loading frame 16, and as shown in Figure 1, described loading frame 16 is removably connected by hook and vehicle frame.Like this when not needing to use loading frame 16, or when needing to change loading frame 16, can be unloaded.In addition, also as shown in Figure 1, described vehicle frame can also be provided with storage disk 3.Storage disk 3 also can be used for placing objects.
Due to travelling aided bicycle in use, sometimes need travelling aided bicycle to brake, at this moment just need, on described vehicle frame, brake assemblies is installed.The effect of brake assemblies is exactly the rotation stoping wheel.The embodiment of brake assemblies has multiple, such as brake disc mechanism.This utility model provides the simple brake assemblies of a kind of structure, uses and installs all very convenient.Described brake assemblies comprises controller 2, brake cable 4 and brake shoes 20, brake shoes 20 is arranged on wheel place and hinged with vehicle frame, and one end of brake shoes 20 is connected with brake cable 4, and this end is also provided with brake shoes back-moving spring, brake cable 4 is connected with controller 2, and controller 2 is arranged on the below of handle 1.Lift by controller 2 one end that brake cable 4 can control brake shoes 20 and press down wheel, thus stop vehicle wheel rotation.The effect of brake shoes back-moving spring is that brake shoes 20 can automatically reset, and now wheel can smooth rotation when after controller 2 releasing of brake line 4.The embodiment of controller 2 has multiple, as long as can control the movement of brake cable 4.
Because the height of user is different, therefore in order to adapt to the user of different height, as shown in Figure 1, described vehicle frame comprises telescopic tube assembly, described telescopic tube assembly comprises outer tube 7 and is arranged on pipe 5 in the moving axially along outer tube of outer tube, described handle 1 is arranged on the upper end of interior pipe 5, and the opening of outer tube 7 is socketed with the stirrup 6 for locating interior pipe 5, stirrup 6 is provided with the control unit 21 for controlling stirrup opening and closing.Stirrup 6 can be unclamped or banding by control unit 21.After stirrup 6 unclamps, interior pipe 5 can slide up and down smoothly along outer tube 7.When after stirrup 6 banding, interior pipe 5 cannot slide up and down.The embodiment of above-mentioned control unit 21 has multiple, such as, can comprise bolt, nut and driving handle etc.Stirrup can unclamp or banding by rotating on bolt by nut.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
