It is to be understood that the "first\second\third" distinguishing objects may be interchanged where appropriate such that the embodiments of the present application described herein may be implemented in sequences other than those illustrated or described herein.
The connection structure described in the embodiment of the present application will be described in detail with reference to fig. 1 to 10.
As shown in fig. 1 to 6, the embodiment of the present application describes a connection structure, which includes a connection shaft 110 disposed on a first sink body 100, a receiving space 210 disposed on a surface of a second sink body 200 and capable of receiving the first sink body 100, and receiving slits 220 disposed on two opposite sidewalls forming the receiving space 210; two ends of the connecting shaft 110 are exposed outside the first sink body 100, and two ends of the connecting shaft 110 are respectively provided with an insertion part 111 matched with the accommodating notch 220; the insertion parts 111 are respectively inserted into the accommodating openings 220, so that the first sink body 100 is located in the accommodating space.
In the present embodiment, a person skilled in the art may set the structure of the first sink body 100 according to actual needs. For example, the first sink 100 may be a rotor or a gear. As one implementation, the first sink 100 may include a wheel.
In the present embodiment, the structure of the second sink body 200 may be set according to actual needs by those skilled in the art. It should be understood by those skilled in the art that the second sink 200 herein corresponds to the first sink 100, and the first sink 100 and the second sink 200 are connected by a connection structure, and finally constitute a product. For example, when the first sink 100 is a rotor, the second sink 200 may be a stator correspondingly; when the first sink 100 is a gear, the second sink 200 may be a housing.
As one implementation, the first sink 100 includes a wheel body, and the second sink 200 is a vehicle body that runs on a supporting surface through the wheel body. The first sink 100 may further include a motor, and the connection shaft 110 is a fixed shaft of the motor; the wheel body is arranged on a rotor outside the motor; the vehicle body provides driving power through a motor in the wheel body. The motor here may be an in-wheel motor.
In this embodiment, a person skilled in the art may set the structure of the accommodating space 210 according to actual needs, as long as the first sink body 100 can be accommodated.
In this embodiment, two opposite side walls of the accommodating space 210 are provided with accommodating slits 220, and the accommodating slits 220 are used for installing the insertion portion 111 of the connecting shaft 110, where the insertion portion 111 is located at or near the end of the connecting shaft 110. The cross-sectional shape of the receiving opening 220 may be set according to actual needs by those skilled in the art. For example, the cross-sectional shape of the accommodating opening 220 may be c-like or u-like. Fig. 1 and 2 exemplarily show that the receiving cutout 220 has a cross-sectional shape similar to an n-shape in order to facilitate the installation of the first sink body 100.
In this embodiment, as shown in fig. 1 and fig. 6, two ends of the connecting shaft 110 are exposed outside the first sink body 100, and two ends of the connecting shaft are respectively provided with an insertion portion 111 matching the accommodating opening 220; the insertion parts 111 are respectively inserted into the accommodating openings 220, so that the first sink body 100 is located in the accommodating space; because the insertion parts 111 on both sides can be inserted into the accommodating openings 220 at the same time, the assembly difficulty is small and the assembly time is short.
Here, the insertion portion 111 is matched with the receiving cutout 220, that is, the shape of the insertion portion 111 is matched with the shape of the receiving cutout 220, so that the insertion portion 111 is smoothly inserted into the receiving cutout 220. The cross-sectional shape of the insertion portion 111 may be set according to actual needs by those skilled in the art, as long as the insertion portion 111 can be inserted into the accommodating cutout 220. For example, the cross-sectional shape of the insertion portion 111 may be rectangular or elliptical. Fig. 3 and 7 exemplarily show that the receiving cutout 220 has a cross-sectional shape similar to an n-shape, and the insertion portion 111 has a cross-sectional shape of a circle.
In some optional implementations of this embodiment, the connection structure may further include a clamping structure, and the insertion portion 111 is clamped on two opposite sidewalls of the accommodating space 210 by the clamping structure, so that the connection shaft 110 is fixedly disposed circumferentially; thereby preventing the connection shaft 110 from rotating in the circumferential direction of the connection shaft 110.
In this embodiment, a person skilled in the art may set the structure of the clamping structure according to actual needs, as long as the connection shaft 110 is prevented from rotating along the circumferential direction of the connection shaft 110. Two specific structures of the chucking structure are listed below by way of example.
For example, in a first specific structure of the clamping structure, the clamping structure includes a card disposed on the insertion portion 111, and clamping grooves disposed on opposite sidewalls of the accommodating space 210, the clamping grooves being matched with the card, the card being clamped in the clamping groove, the insertion portion 111 being clamped in the clamping groove by the card to fix the connection shaft 110 along a circumferential direction of the connection shaft 110; the connection shaft 110 is prevented from rotating in the circumferential direction of the connection shaft 110.
As another example, as shown in fig. 6 and 10, in a second specific structure of the clamping structure, the insertion portion 111 is cylindrical, the clamping structure includes a first concave plane 112, the first concave plane 112 is located on a cylindrical surface of the insertion portion 111, and a distance between a surface of the cylindrical surface of the insertion portion 111 opposite to the first concave plane 112 and the first concave plane 112 matches a width of the accommodating gap 220; the first concave plane 112 is located on the width side of the accommodating opening 220; the insertion portion 111 is clamped in the accommodating opening 220 through the first concave plane 112, so that the connection shaft 110 is fixedly arranged in the circumferential direction; thereby preventing the connection shaft 110 from rotating in the circumferential direction of the connection shaft 110.
Here, the distance between the surface of the cylindrical surface of the insertion portion 111 opposite to the first concave plane 112 and the first concave plane 112 is matched with the width of the accommodating gap 220, that is, the distance between the surface of the cylindrical surface of the insertion portion 111 opposite to the first concave plane 112 and the first concave plane 112 is similar to the width of the accommodating gap 220, so that when the insertion portions are respectively inserted into the accommodating gaps, the gap between the first concave plane 112 and the accommodating gap 220 is as small as possible. Here, the distance between the surfaces of the cylindrical surface of the insertion portion 111 opposite to the first concave plane 112 is similar to the width of the accommodating gap 220 and is smaller than the diameter of the insertion portion 111, and the first concave plane 112 is disposed on the width side of the accommodating gap 220, so that the connection shaft 110 cannot be rotated due to the larger diameter of the insertion portion 111; thereby achieving a circumferentially fixed arrangement of the connecting shaft 110.
It will be appreciated by those skilled in the art that the gripping structure herein further comprises a portion of the insertion portion 111 connected to the first recess plane 112, and that the portion of the insertion portion 111 connected to the first recess plane 112 forms a platform structure, i.e. a gripping structure, with the first recess plane 112. Here, the first concave plane 112 is the main working surface of the chucking structure.
It will be appreciated by those skilled in the art that the insertion portion 111 may also fix the connection shaft 110 along the circumferential direction of the connection shaft 110 by means of two recessed planes. As an implementation manner, as shown in fig. 10, the clamping structure further includes a second concave plane 117, where the second concave plane 117 is located on an opposite side of the first concave plane 112, and a distance between the second concave plane 117 and the first concave plane 112 matches a width of the accommodating gap 220; the first concave planes 112 are respectively located at one side of the width sides of the accommodating gaps 220, and the second concave planes 117 are respectively located at the other side of the width sides of the accommodating gaps 220; the insertion portion 111 is clamped in the accommodating opening 220 by the first concave plane 112 and the second concave plane 117, so that the connecting shaft 110 is circumferentially fixed.
Here, the distance between the second concave plane 117 and the first concave plane 112 is matched with the width of the accommodating gap 220, that is, the distance between the second concave plane 117 and the first concave plane 112 is matched with the width of the accommodating gap 220, so that when the insertion parts are respectively inserted into the accommodating gaps, the gap between the first concave plane 112 and the accommodating gap 220 is as small as possible, and the gap between the second concave plane 117 and the accommodating gap 220 is as small as possible. Here, the distance between the second concave plane 117 and the first concave plane 112 is similar to the width of the accommodating gap 220 and is smaller than the diameter of the insertion portion 111, the first concave plane 112 is disposed at one side of the width of the accommodating gap 220, the second concave plane 117 is disposed at the other side of the width of the accommodating gap 220, and the connecting shaft 110 cannot be rotated due to the larger diameter of the insertion portion 111; thereby achieving a circumferentially fixed arrangement of the connecting shaft 110.
It will be appreciated by those skilled in the art that the gripping structure herein further comprises a portion of the insertion portion 111 connected to the first recess plane 112 and the second recess plane 117, respectively, and that the portion of the insertion portion 111 connected to the first recess plane 112 and the second recess plane 117, respectively, the first recess plane 112 and the second recess plane 117 together form a platform structure, i.e. a gripping structure. Here, the first recess plane 112 and the second recess plane 117 are the main working surfaces of the clamping structure.
In some optional implementations of this embodiment, as shown in fig. 4, the connection structure may further include two first bearing pads 300, and sink slots 230 respectively disposed on the outer sides of two opposite sidewalls of the accommodating space 210 and respectively corresponding to the accommodating openings 220; the two ends of the connecting shaft 110 are respectively provided with a first bearing part 113 corresponding to the sinking groove 230; the outer rings of the two first bearing gaskets 300 are respectively matched with the sinking grooves 230, and the inner holes of the two first bearing gaskets 300 are respectively matched with the first bearing parts 113; the inner holes of the two first bearing gaskets 300 are respectively sleeved on the first bearing parts 113, the outer rings of the two first bearing gaskets 300 are respectively clamped in the sinking grooves 230, and the first bearing parts 113 bear the second sink body 200 through the two first bearing gaskets 300.
In this implementation manner, the inner holes of the two first bearing gaskets 300 are respectively sleeved on the first bearing parts 113, the outer rings of the two first bearing gaskets 300 are respectively clamped in the sinking grooves 230, and the first bearing parts 113 bear the second sink body 200 through the two first bearing gaskets 300; the gravity and/or the external force borne by the second sink 200 is transmitted to the two first bearing gaskets 300 through the outer rings of the two first bearing gaskets 300, and then transmitted to the first bearing part 113 through the inner holes of the two first bearing gaskets 300; in this way, since the contact area of the second sink body 200 is increased by the two first bearing pads 300, the pressure of the second sink body 200 becomes smaller, the supporting performance of the second sink body 200 can be increased, and when the second sink body 200 is too much stressed, the damage of the stressed contact surface of the second sink body 200 can be effectively prevented.
In this implementation, one skilled in the art may set the thickness and diameter of the first load bearing gasket 300 according to the weight of the second sink body 200 or/and the external force that the second sink body 200 receives. It will be appreciated that the greater the thickness of first load bearing shim 300 and/or the greater the diameter of first load bearing shim 300, the greater the area of force bearing contact and thus the load bearing capacity of second sink body 200.
In this implementation manner, as shown in fig. 3 and fig. 4, the sink 230 corresponds to the accommodating opening 220, that is, the sink 230 is disposed at the accommodating opening 220, so that the first bearing portion 113 is located at the sink 230, and when the inner holes of the two first bearing gaskets 300 are respectively sleeved on the first bearing portion 113, the outer rings of the two first bearing gaskets 300 are respectively clamped in the sink 230.
Here, the countersink 230 is used for clamping the first bearing pads 300, and the outer rings of the two first bearing pads 300 are respectively matched with the countersink 230, that is, the shape of the countersink 230 is matched with the shape of the outer rings of the two first bearing pads 300. The sectional shape of the sinking groove 230 may be set by a person skilled in the art according to actual needs, as long as the two first bearing pads 300 can be respectively clamped in the sinking groove 230. It should be understood by those skilled in the art that when the cross-sectional shape of the countersink 230 is circular, the contact area between the countersink 230 and the outer ring of the first carrier spacer 300 can be increased; thereby increasing the supporting performance of the connection shaft 110 to the second sink 200. The sink 230 may be directly disposed on the outer sides of the opposite sidewalls of the accommodating space 210, or may be disposed on the outer sides of the opposite sidewalls of the accommodating space 210 by other structures. For example, as shown in fig. 10, the connection structure may further include limit ribs 231 respectively disposed on the outer sides of the opposite sidewalls of the accommodating space 210 and respectively corresponding to the accommodating openings 220; the limiting rib 231 forms the sink 230 near the side of the accommodating opening 220. Here, the number of the limit ribs 231 may be one or more. When the number of the limit ribs 231 is one, one limit rib 231 is clamped with the first bearing gasket 300; when the number of the limiting ribs 231 is plural, the plurality of limiting ribs 231 jointly clamp the first bearing pad 300. Fig. 10 exemplarily shows that the cross section of the limiting rib 231 is circular, and the limiting rib 231 has an opening on the side of the accommodating gap 220, and the width of the opening is smaller than the diameter of the inner ring surface of the limiting rib 231 near the side of the accommodating gap 220; so that the first bearing pad 300 is clamped in the countersink 230 to limit the movement of the connecting shaft 110 along the direction away from the accommodating gap 220, thereby preventing the connecting shaft 110 from being separated from the accommodating gap 220.
Here, the first bearing portion 113 is configured to support the first bearing pads 300, and the inner holes of the two first bearing pads 300 are respectively matched with the first bearing portion 113, that is, the shape of the first bearing portion 113 is matched with the shape of the inner holes of the two first bearing pads 300. The cross-sectional shape of the first bearing portion 113 may be set by those skilled in the art according to actual needs, so long as the two first bearing pads 300 can be sleeved on the first bearing portion 113. Fig. 3 and 6 exemplarily show that the cross-sectional shape of the first bearing portion 113 is circular so as to be able to increase the contact area of the first bearing portion 113 with the inner hole of the first bearing pad 300; thereby increasing the supporting performance of the second sink 200. Here, the gap between the first bearing portion 113 and the two first bearing pads 300 may be set according to actual needs by those skilled in the art. For example, the diameter of the first bearing portion 113 may be equal to the diameter of the inner hole of the first bearing pad 300, may be greater than the diameter of the inner hole of the first bearing pad 300, or may be less than the diameter of the inner hole of the first bearing pad 300. It should be understood by those skilled in the art that when the inner holes of the two first bearing pads 300 are respectively sleeved on the first bearing portions 113, the smaller the gap between the first bearing portions 113 and the two first bearing pads 300, the larger the contact area, and the better the bearing performance of the first bearing pads 300.
It should be understood by those skilled in the art that when the connection structure includes both the clamping structure and the first bearing portion 113, the clamping structure may be directly disposed on the first bearing portion 113 or may not be disposed on the first bearing portion 113. Fig. 10 exemplarily shows that the chucking structure includes a first concave plane 112 and a second concave plane 117, and the first concave plane 112 and the second concave plane 117 are disposed on the first bearing 113.
In some alternative implementations of the present embodiment, the connection structure further includes two second load-bearing shims 400; the two ends of the connecting shaft 110 are respectively provided with a second bearing part 114 corresponding to the outer side surfaces of the two opposite side walls of the accommodating space 210; the second bearing portion 114 is provided with positioning shoulders 115 respectively matching with outer side surfaces of two opposite side walls of the accommodating space 210; the inner holes of the two second bearing gaskets 400 are respectively matched with the second bearing parts 114; the inner holes of the two second bearing gaskets 400 are respectively sleeved on the second bearing part 114.
In this implementation, one skilled in the art may set the thickness of second load bearing shim 400 based on the axial force that second load bearing shim 400 is subjected to. It will be appreciated that the greater the thickness of the second load bearing shim 400, the greater the axial force that can be tolerated.
In this embodiment, in order to prevent the second bearing pads 400 from applying too much force to the second sink 200 to damage the second sink 200, the second bearing portions 114 are respectively provided with positioning shoulders 115 matching with outer side surfaces of two opposite side walls of the accommodating space 210. The following exemplary three setting positions of the positioning shoulder 115 are mainly described by taking one side of the opposite side walls of the accommodating space 210 as an example, and the other side of the opposite side walls of the accommodating space 210 is similar, which is not described herein again.
For example, as shown in fig. 9, in the first setting position of the positioning shaft shoulder 115, one side of the second bearing pad 400 abuts against the positioning shaft shoulder 115, and a first preset distance H1 is formed between one side of the second bearing pad 400 and the outer side of one side of the opposite side walls of the accommodating space 210; in this way, the second load bearing shim 400 is subjected to the force exerted by the second load bearing shim 400 via the locating shoulder 115; the deformation of one side of the opposite side walls of the accommodating space 210 is effectively prevented from being too large, and the second sink 200 is prevented from being damaged. Here, the smaller the first preset distance H1, the better to prevent the second sink body 200 from axially moving in the connection shaft 110.
As another example, as shown in fig. 8, in the second setting position of the positioning shoulder 115, one side of the second bearing pad 400 abuts against the outer side surface of one side of the opposite two sidewalls of the accommodating space 210, and a second preset distance H2 is formed between one side of the second bearing pad 400 and the positioning shoulder 115; in this way, the second bearing pad 400 receives the force applied by the second bearing pad 400 through one side of the opposite sidewalls of the accommodating space 210; when the force applied by the two second bearing pads 400 is too large to cause the deformation of one side of the opposite side walls of the accommodating space 210 to reach the second preset distance H2, the second bearing pads 400 contact with the positioning shaft shoulder 115, and can also bear the force applied by the second bearing pads 400 through the positioning shaft shoulder 115; the second sink 200 can be effectively prevented from being damaged due to too large deformation of one side of the opposite side walls of the accommodating space 210. Here, the smaller the second preset distance H2, the better to reduce the deformation amount of the second sink body 200.
As another example, as shown in fig. 7, one side of the second bearing pad 400 abuts against the positioning shoulder 115, and abuts against the outer side surfaces of one side of the opposite side walls of the accommodating space 210; in this way, the second bearing pad 400 bears the force applied by the second bearing pad 400 by positioning the shaft shoulder 115 and one side of the opposite side walls of the accommodating space 210, so that the deformation of one side of the opposite side walls of the accommodating space 210 can be effectively prevented from being too large, and the second sink 200 is damaged; while also preventing axial play of the second sink body 200 in the connection shaft 110.
In this embodiment, the fixing manner of the two second bearing pads 400 at the two ends of the connecting shaft 110 is not limited. Two ways of securing the two second carrier shims 400 at the ends of the connecting shaft 110 are exemplarily listed below.
For example, in the first fixing manner of the two second bearing gaskets 400 at two ends of the connecting shaft 110, the connecting structure may include a collar, and the two ends of the connecting shaft 110 further have grooves matched with the collar, and the collar is located in the grooves.
For another example, in the second fixing manner of the two second bearing gaskets 400 at the two ends of the connecting shaft 110, as shown in fig. 3, the two ends of the connecting shaft 110 further have screw portions 116 adjacent to the second bearing portions 114, and the screw portions 116 are located outside the second bearing portions 114; the connecting structure further comprises two nuts 600 respectively matched with the threaded portions 116, wherein the two nuts 600 are respectively connected with the threaded portions 116 and respectively abut against the two second bearing gaskets 400 to press the two second bearing gaskets 400. It should be understood by those skilled in the art that the connection structure may further include a locking washer 500 in order to prevent the two nuts 600 from being loosened; the anti-loose gaskets 500 are respectively sleeved at two ends of the connecting shaft 110 and are positioned between the two nuts 600 and the two second bearing gaskets 400; the anti-loose washer 500 is respectively abutted against the two nuts 600 and the two second bearing washers 400.
It will be appreciated by those skilled in the art that second carrier shim 400 and first carrier shim 300 may be the same shim or may be different shims. Fig. 7-9 exemplarily illustrate that the first carrier spacer 300 and the second carrier spacer 400 are the same spacer, and the first carrier portion 113 and the second carrier portion 114 are the same shaft section; in this way, the second load bearing gasket 400 can bear both the second sink 200 and the axial force.
In this embodiment, two ends of the connection shaft 110 are exposed outside the first sink body 100, and two ends of the connection shaft 110 are respectively provided with an insertion portion 111 matching the accommodating opening 220; the insertion parts 111 are respectively inserted into the accommodating openings 220, so that the first sink body 100 is located in the accommodating space; because the insertion parts 111 on both sides can be inserted into the accommodating openings 220 at the same time, the assembly difficulty is small and the assembly time is short.
The embodiment of the application also discloses a running device, which comprises the connecting structure disclosed by the embodiment of the application.
The traveling device may be a robot or a balance car.
The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes and substitutions are intended to be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
