Certainly, according to actual needs, conversion equipment 23 can also have overturning connection or dismantling connection for other forms The bindiny mechanism of function, combining form can also take multiple combinations mode.

The application method of above-mentioned Multifunctional walk learning cycle for baby, can refer to Figure 14 and Figure 15:

Multifunctional walking chair is used as row go-cart is sat, and under auto mode, chassis is O shape:

Baby may stand among the seat hole 12 of panel 11, pass through the support leg exercising strength of panel 11 and cushion 13 Cultivate the sense of equilibrium.At this point, locked conversion equipment 23, locks between fixed underpan 21 and movable tray 22, so that fixed underpan 21 Stable O shape structure is formed with movable tray 22.

Multifunctional walking chair is used as go-cart is carried out, and under implementation mode, chassis is D-shaped:

During chassis 2 is converted to D-shaped by O shape, conversion equipment 23 is unlocked, by movable tray 22 from chassis assembly 2 It disassembles, and the direction on translation activity chassis 22 is installed to fixed underpan 21 and forms D-shape configuration.

During chassis 2 is converted to D-shaped by O/ ellipse, conversion equipment 23 is unlocked, by about 22 180 degree of movable tray It turns, is connect with fixed underpan 21, then locked conversion equipment 23, so that fixed underpan 21 and movable tray 22 form D-shaped Structure.

In order to further optimize the above technical scheme, rotating shaft mechanism includes the rotary shaft for being set to 21 end of fixed underpan 231, and it is set to 22 end of movable tray and the rotating hole 233 for the connection that matches with rotary shaft 231；

Or；

Rotating shaft mechanism includes the rotary shaft 231 for being set to 22 end of movable tray, and is set to 21 end of fixed underpan And the rotating hole 233 for the connection that matches with rotary shaft 231.

Using above-mentioned connection structure, movable tray 22 is rotatably connected relative to fixed underpan 21.231 end energy of rotary shaft It is enough caught in rotating hole 233, and is rotatably connected relative to rotating hole 233.

In order to further optimize the above technical scheme, clamping mechanism includes the engaging slot for being set to 21 end of fixed underpan 232, and it is movably connected on 22 end of movable tray and the activity control switch 234 for the clamping that matches with engaging slot 232；

Or；

Clamping mechanism includes the engaging slot 232 for being set to 22 end of movable tray, and is movably connected on fixed underpan 21 The activity control switch 234 of end and the clamping that matches with engaging slot 232.

Using above-mentioned connection structure, movable tray 22 is detachably connected relative to the connecting pin of fixed underpan 21.

In order to further optimize the above technical scheme, activity control switch 234 includes spring 2342 and connecting spring 2342 column 2341 that is slidably fastened.Specifically, deep gouge can be set on movable tray 22 or fixed underpan 21, for placing movable control Switch 234 is made, column 2341 provides slide-and-guide to be slidably fastened.

Further combined with above-mentioned specific embodiment, during chassis 2 is converted to D-shaped by O shape, three kinds of conversion equipment 23 Form specific structure is as follows:

(the first conversion equipment and the second conversion equipment are that rotating shaft mechanism is mutually tied with clamping mechanism for the first specific structure Close), as shown in Figure 10, fixed underpan 21 and movable tray 22 do not depart from always, can be converted by rotation mode.To middle slip Two of 22 both ends of movable tray are slidably fastened column 2341, skid off it from engaging slot 232, movable tray 22 and fixed underpan 21 separation.Then, it is axis with the rotary shaft 231 at both ends, overturns movable tray 22 forward, be caught in two columns 2341 that are slidably fastened In engaging slot 232, movable tray 22 and fixed underpan 21 engage again at this time.

Second specific structure (the first conversion equipment and the second conversion equipment be clamping mechanism), as shown in figure 12, Gu Determine chassis 21 and 22 both ends of movable tray while being separated, can be realized by way of mobile disassembly.To middle slip dump bottom Two of 22 both ends of disk are slidably fastened column 2341, skid off it from engaging slot 232, movable tray 22 and fixed underpan 21 divide From.Then movable tray 22 is moved and overturn, is caught in two columns 2341 that are slidably fastened in engaging slot 232, at this time movable tray 22 and fixed underpan 21 engage again.

The third specific structure (the first conversion equipment is rotating shaft mechanism and the second conversion equipment is clamping mechanism), such as Figure 11 Shown, fixed underpan 21 and 22 one end of movable tray are detached from one end and do not depart from, and can be realized by way of mobile rotation.Sliding card Zygostyle 2341 skids off it from engaging slot 232, and rotates movable tray 22, so that rotating hole 233 is rotated around rotary shaft 231, The column 2341 that makes to be slidably fastened is caught in again in engaging slot 232, and movable tray 22 and fixed underpan 21 engage again at this time.

For this programme there are also the combination of other conversion equipments, fit system is similar to above scheme principle, herein no longer It repeats one by one.

The above-mentioned design synthesis advantage and disadvantage of mesh first two structure go-cart, i.e., round go-cart stable structure, but it is inconvenient Carry out from rear, it is convenient that U-shaped go-cart is carried out, but is easy rollover.This programme is started with from the structure for improving existing round go-cart, By the improvement of structure, the advantages of merging above two go-cart so that round go-cart both can be used as with cushion from Line go-cart can also be used as the use of implementation formula go-cart, thus be converted to it is a can voluntarily and multi-functional that can carry out Walk vehicle.

Finally, it is to be noted that, herein, relational terms such as first and second and the like be used merely to by One entity or operation are distinguished with another entity or operation, without necessarily requiring or implying these entities or operation Between there are any actual relationship or orders.Moreover, the terms "include", "comprise" or its any other variant meaning Covering non-exclusive inclusion, so that the process, method, article or equipment for including a series of elements not only includes that A little elements, but also including other elements that are not explicitly listed, or further include for this process, method, article or The intrinsic element of equipment.In the absence of more restrictions, the element limited by sentence "including a ...", is not arranged Except there is also other identical elements in the process, method, article or apparatus that includes the element.

Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other The difference of embodiment, the same or similar parts in each embodiment may refer to each other.

The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The widest scope consistent with features of novelty.
