The following describes a specific implementation of the present invention in more detail with reference to specific embodiments:
referring to fig. 1, 2 and 5, an embodiment of the present invention provides an adapter assembly for connecting a driving wheel 100 'and a driving turntable 200', wherein the adapter assembly includes an adapter body 100, a limiting structure 200 and a self-locking structure 300. It should be noted that, the connection between the driving wheel 100 ' and the driving turntable 200 ' can be realized through the adapter assembly, and when the driving turntable 200 ' rotates, the driving turntable 200 ' can drive the adapter assembly and the driving wheel 100 ' to rotate synchronously. The switching assembly provided by the embodiment is particularly suitable for a scene that the driving wheel 100 'is a mecanum wheel, the traditional mecanum wheel can be connected with the driving turntable 200' only by adopting a plurality of screws, and the convenience in disassembly and assembly of the mecanum wheel can be greatly improved by the switching assembly provided by the embodiment.
Wherein, the adapting body 100 is connected to one side of the driving wheel 100 'facing the driving turntable 200'; referring to fig. 9 and 10, at least two limiting structures 200 are provided, each limiting structure 200 includes a positioning hole 201 and a limiting groove 202 disposed at the bottom of the positioning hole 201; the number of the self-locking structures 300 is at least two, each self-locking structure 300 comprises a positioning pin 310 and a limiting protrusion 320, the positioning pin 310 is used for being matched with the positioning hole 201 in an inserting mode, the limiting protrusion 320 is connected to one end, facing the positioning hole 201, of the positioning pin 310 and extends outwards to form the limiting protrusion, and the limiting protrusion 320 is elastically clamped in the limiting groove 202. Specifically, the limiting protrusion 320 generates elastic deformation when moving from the positioning hole 201 to the limiting groove 202, and recovers the elastic deformation in the limiting groove 202 and is limited in the limiting groove 202; the positioning hole 201 is opened at one side of the driving turntable 200 'facing the adapter body 100, and one end of the positioning pin 310 departing from the limiting protrusion 320 is connected to one side of the adapter body 100 facing the driving turntable 200'; or, the positioning hole 201 is opened at one side of the adapting body 100 facing the driving turntable 200 ', and one end of the positioning pin 310 departing from the limiting protrusion 320 is connected to one side of the driving turntable 200' facing the adapting body 100.
It should be noted that, one of a side of the adaptor body 100 facing the driving turntable 200 'and a side of the driving turntable 200' facing the adaptor body 100 is provided with the self-locking structure 300, and the other is provided with the limiting structure 200. When there are a plurality of self-locking structures 300, a part of the self-locking structures 300 is disposed on the side of the adaptor body 100 facing the driving turntable 200 ', and another part of the self-locking structures is disposed on the side of the driving turntable 200' facing the adaptor body 100. And, the respective lock structures 300 disposed on the same side are also disposed to be staggered with each other. And each of the position-limiting structures 200 is disposed corresponding to each of the lock structures 300. The radial section size of the positioning pin 310 is smaller than or equal to the section size of the positioning hole 201, so that the positioning pin 310 and the positioning hole 201 can be conveniently sleeved; the maximum radial cross-sectional dimension of the limiting protrusion 320 is greater than the cross-sectional dimension of the positioning hole 201 and less than or equal to the radial cross-sectional dimension of the limiting groove 202, so that the limiting protrusion 320 is self-locked in the limiting groove 202.
Specifically, based on the structure of the present embodiment, when the adaptor body 100 and the driving dial 200' are connected, the operator can align the limiting protrusion 320 and the positioning pin 310 with the opening of the positioning hole 201, and apply a force to make the limiting protrusion 320 and the positioning pin 310 enter the positioning hole 201 and move along the extending direction of the positioning hole 201, the limiting protrusion 320 will be compressed and elastically deformed in the positioning hole 201 because the maximum cross-sectional dimension thereof is larger than the cross-sectional dimension of the positioning hole 201 until the limiting protrusion 320 moves to the limiting groove 202, and in the limiting groove 202, the limiting protrusion 320 will recover the elastic deformation because the accommodating space is more sufficient, and therefore, the limiting protrusion 320 will be limited in the limiting groove 202, and in case that no sufficient external force directed to the opening side of the positioning hole 201 is applied to the limiting protrusion 320, the limiting protrusion 320 will not return to the positioning hole 201 from the limiting groove 202, and based on this, the locking structures 300 and the limiting structures 200 can be connected respectively at one time through one-time force application, the operation is very simple and convenient, and the connection stability and the reliability are better. Based on the connection relationship, in combination with the connection relationship between the adapter body 100 and the driving wheel 100 ', when the driving turntable 200' rotates, the driving turntable 200 'can drive the driving wheel 100' to rotate synchronously through the adapter assembly.
When the connection between the adapter body 100 and the driving dial 200' is released, the operator may apply an external force to the limiting protrusion 320 and the positioning pin 310 toward the opening of the positioning hole 201, and when the acting force is sufficient, the limiting protrusion 320 will withdraw from the limiting groove 202 to the positioning hole 201, and will be compressed in the positioning hole 201 to generate elastic deformation, and continuously apply the acting force, so that the limiting protrusion 320 and the positioning pin 310 can be separated from the opening of the positioning hole 201, and based on this, the connection between each locking structure 300 and each limiting structure 200 can be released at one time by one-time force application, and the operation is very simple. Based on this, the present embodiment easily realizes the driving switching and detaching work of the driving turntable 200 'and the driving wheel 100' through the switching assembly.
In summary, in the adapter assembly provided in the embodiments of the present invention, the adapter body 100 is connected to the driving wheel 100 ', and then the limiting protrusions 320 and the positioning pins 310 are inserted into the positioning holes 201 from the aperture sides of the positioning holes 201, the limiting protrusions 320 are elastically deformed under the action of the force and gradually penetrate into the positioning holes 201 until the limiting protrusions move to the limiting grooves 202, and the limiting protrusions 320 are elastically deformed and self-locked to the limiting grooves 202 in the limiting grooves 202, so that the respective locking structures 300 can be easily and stably connected to the limiting structures 200, and the driving wheel 100 ' and the driving turntable 200 ' can be connected to each other, and the driving wheel 100 ' and the driving turntable 200 ' can rotate synchronously. When the connection between the driving wheel 100 'and the driving turntable 200' needs to be released, a certain pulling force can be applied to each limiting protrusion 320 and each positioning pin 310, so that the limiting protrusions 320 are forced to generate elastic deformation under the action of the force and retreat from the limiting grooves 202 to the positioning holes 201, and the connection between each locking structure 300 and each limiting structure 200 can be released, and the connection between the driving wheel 100 'and the driving turntable 200' can be released. The switching assembly provided by the embodiment of the invention can complete the installation or the disassembly of the respective locking structure 300 and the respective limiting structure 200 through one-time operation, greatly simplifies the disassembly and assembly operation between the driving wheel 100 'and the driving turntable 200', can ensure and improve the disassembly and assembly convenience between the driving wheel 100 'and the driving turntable 200' to a certain extent, and is beneficial to the installation, later maintenance, replacement and other operations of the driving wheel 100 'and the driving turntable 200' with high efficiency.
Referring to fig. 5, 6 and 7, in the present embodiment, the limiting protrusion 320 has a first limiting portion 321, and a cross-sectional dimension of the first limiting portion 321 along the radial direction is gradually enlarged from a side facing the adapting body 100 to a side facing away from the adapting body 100. The cross-sectional shape of the outer surface of the first stopper 321 may be linear or arc, which is not limited in this embodiment.
By adopting the scheme, the maximum sectional dimension of the limiting protrusion 320 can still be ensured to be larger than the sectional dimension of the positioning hole 201 and smaller than or equal to the sectional dimension of the limiting groove 202, so that the limiting protrusion 320 can be self-locked in the limiting groove 202; and when the connection between the adapter body 100 and the driving turntable 200 ' is released, the first limiting portion 321 with gradually changed cross-sectional dimension allows the first limiting portion 321 to more smoothly return from the limiting groove 202 to the positioning hole 201, so that the pulling force required to be applied when the self-locking condition of the limiting protrusion 320 is released can be correspondingly reduced, the operational convenience of releasing the self-locking state of the limiting protrusion 320 can be ensured and improved, and the convenience of disassembly and assembly between the driving wheel 100 ' and the driving turntable 200 ' can be further improved.
Referring to fig. 5, 6 and 7, in the present embodiment, the limiting protrusion 320 further has a second limiting portion 322 connected to a side of the first limiting portion 321 away from the adapting body 100, and a cross-sectional dimension of the second limiting portion 322 along the radial direction is tapered from a side facing the adapting body 100 to a side away from the adapting body 100. The cross-sectional shape of the outer surface of the second stopper 322 may be linear or arc, which is not limited in this embodiment.
By adopting the scheme, the maximum sectional dimension of the limiting protrusion 320 can still be ensured to be larger than the sectional dimension of the positioning hole 201 and smaller than or equal to the sectional dimension of the limiting groove 202, so that the limiting protrusion 320 can be self-locked in the limiting groove 202; and when the adapter body 100 and the driving turntable 200 ' are connected, the second limiting portion 322 with gradually changed cross-sectional dimension allows the second limiting portion 322 to enter the positioning hole 201 more smoothly from the orifice side of the positioning hole 201, so that the magnitude of the pushing force required to be applied when the limiting protrusion 320 enters the positioning hole 201 can be correspondingly reduced, the connection convenience between the self-locking structure 300 and the limiting structure 200 can be ensured and improved, and the disassembly and assembly convenience between the driving wheel 100 ' and the driving turntable 200 ' can be further improved.
Referring to fig. 7 and 8, in the present embodiment, at least one deformation groove 311 is formed on a side of the positioning pin 310 facing the positioning hole 201, and the deformation groove 311 is disposed through in an extending direction thereof. Here, the extending directions of the deformation grooves 311 of the plurality of positioning pins 310 may be different. The positioning pin 310 is broken at least at the opening of the deformation groove 311 by the deformation groove 311 provided through in the extending direction, and for example, as shown in fig. 4, when the number of the openings of the deformation groove 311 is one, the positioning pin 310 is divided into two at the opening of the deformation groove 311. Based on this, through the arrangement of the deformation groove 311, when the limiting protrusion 320 is located in the positioning hole 201 and is elastically deformed due to the extrusion of the hole wall of the positioning hole 201, the spatial region where the deformation groove 311 is located is used as the deformation region of the limiting protrusion 320 and the positioning pin 310 of the portion, so as to facilitate the limiting protrusion 320 and the positioning pin 310 close to the limiting protrusion 320 to adaptively generate elastic deformation, which not only can reduce the degree of resistance between the limiting protrusion 320 and the positioning hole 201, reduce the pressure condition between the limiting protrusion 320 and the positioning pin 310 close to the limiting protrusion 320, but also can effectively reduce the friction and wear condition between the limiting protrusion 320 and the positioning hole 201, thereby further improving the convenience of assembly and disassembly between each lock structure 300 and each limiting structure 200, and further improving the convenience of assembly and disassembly between the driving wheel 100 'and the driving turntable 200'.
Referring to fig. 7 and 8, in the present embodiment, the groove depth of the deformation groove 311 is smaller than the axial length of the positioning pin 310. By adopting the scheme, on the basis of reserving deformation spaces for generating adaptive deformation for the limiting protrusions 320 and the positioning pins 310 close to the limiting protrusions 320, the connection strength between the positioning pins 310 and the adapter body 100 is guaranteed and improved, and the supporting strength of the bottom of the positioning pins 310 to the positioning pin 310 part provided with the deformation grooves 311 and the limiting protrusions 320 is guaranteed and improved, so that the effectiveness and the service life of the adapter assembly can be further guaranteed and improved.
Referring to fig. 7 and 8, in the present embodiment, a pressure release hole 312 is further formed on one side of the positioning pin 310 facing the positioning hole 201 and extends along the axial direction. It should be noted that, by opening the pressure release hole 312, at least a part of the positioning pin 310 is disposed in a cylindrical shape, and thus, when the limiting protrusion 320 is located in the positioning hole 201 and is elastically deformed due to the extrusion of the hole wall of the positioning hole 201 and drives the positioning pin 310 close to the limiting protrusion to adaptively elastically deform, the mutual extrusion of the positioning pins 310 at both sides of the deformation groove 311 can be effectively reduced, the extrusion pressure of the positioning pins 310 can be effectively reduced, thereby further limiting the resistance degree and pressure condition between the protrusion 320 and the positioning pin 310 and the positioning hole 201, further reducing the friction and abrasion between the limiting protrusion 320 and the positioning pin 310 and the positioning hole 201, thereby further improving the convenience of assembly and disassembly between the lock structures 300 and the limit structures 200, so as to further improve the convenience of assembly and disassembly between the driving wheel 100 'and the driving turntable 200'.
Referring to fig. 7 and 8, in the present embodiment, the extension length of the pressure relief hole 312 is greater than or equal to the groove depth of the deformation groove 311. By adopting the above scheme, the mutual extrusion of the positioning pins 310 close to the two sides of the limiting protrusion 320 and the deformation groove 311 can be further avoided, the mutual extrusion pressure of the positioning pins 310 at the opening region of the deformation groove 311 can be further reduced, so that the resistance degree and the pressure between the limiting protrusion 320 and the positioning pins 310 and the positioning holes 201 can be further reduced, the friction and the abrasion between the limiting protrusion 320 and the positioning pins 310 and the positioning holes 201 can be further reduced, the disassembly and assembly convenience between the respective lock structures 300 and the respective limiting structures 200 can be further improved, and the disassembly and assembly convenience between the driving wheel 100 'and the driving turntable 200' can be further improved.
Referring to fig. 3, fig. 5 and fig. 10, in the present embodiment, the limiting structure 200 further includes a stopping portion 203 disposed in the opening of the positioning hole 201; the self-locking structure 300 further includes a stopping protrusion 330 connected to one end of the positioning pin 310 away from the positioning hole 201 and extending outward, and the stopping protrusion 330 is used for being in limit fit with the stopping portion 203. It should be noted that the radial dimension of the stopping portion 203 is larger than the radial dimension of the positioning hole 201, and the cross-sectional dimension of the stopping protrusion 330 is larger than the cross-sectional dimension of the positioning hole 201 and smaller than or equal to the cross-sectional dimension of the stopping portion 203. When the limiting protrusion 320 is limited in the limiting groove 202 and the positioning pin 310 is sleeved in the positioning hole 201, the stopping protrusion 330 is received and stopped at the stopping portion 203. Based on the arrangement of the stopping protrusion 330 and the stopping portion 203, after the limiting protrusion 320 is limited in the limiting groove 202, the limiting protrusion 320 and the positioning hole 201 are limited to continue to move towards one side of the limiting groove 202, and then, in combination with the effect of the limiting protrusion 320 on limiting the self-locking structure 300 to move towards one side of the stopping portion 203, the self-locking structure 300 is relatively fixed relative to the limiting structure 200. Therefore, by adopting the above scheme, the position between the self-locking structure 300 and the limiting structure 200 can be ensured to be in a relatively stable state, so that the connection stability between the driving wheel 100 'and the driving turntable 200' can be further ensured and improved.
Referring to fig. 2, 7 and 8, in the present embodiment, the respective locking structures 300 are arranged in a central circumferential array relative to the adaptor body 100 or the driving turntable 200'.
