The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

A steering device 100 of a balance car according to an aspect of the present invention will be described below with reference to fig. 1 to 6.

The steering apparatus 100 of the balance car includes a rotating shaft 110, a bracket 120, and an elastic member 130.

The bracket 120 includes a shaft bracket 121 and a support base 122. The shaft holder 121 is provided on the support base 122, and the shaft holder 121 has a shaft hole in which the rotation shaft 110 is rotatably fitted.

The support base 122 has a first support portion 1221 and a second support portion 1222. The shaft hole is located between the first support 1221 and the second support 1222 in the first preset direction. The elastic member 130 has a first end 131 and a second end 132 opposite in a first predetermined direction. The first end 131 of the elastic member 130 is supported on the first support 1221, and the second end 132 of the elastic member 130 is supported on the second support 1222.

The elastic member 130 is engaged with the rotation shaft 110 to be deformed when the rotation shaft 110 rotates, i.e., the rotation shaft 110 causes the elastic member 130 to be deformed.

For convenience of description, the following describes the technical solution of the present application by taking the first preset direction as a left-right direction and the second preset direction as an up-down direction as an example. The left-right direction and the up-down direction are indicated by arrows in fig. 1, and the height direction of the holder 120 is the up-down direction.

In some embodiments, as shown in fig. 1, the supporting base 122 includes a bottom plate 1223, and a first supporting base 1224 and a second supporting base 1225 disposed on the bottom plate 1223. The base plate 1223 is horizontally disposed, and the first support base 1224 and the second support base 1225 are disposed on an upper surface of the base plate 1223. That is, the lower end of each of the first and second supporting

seats

1224 and 1225 is connected to the base plate 1223, and each of the first and second supporting

seats

1224 and 1225 extends upward from the base plate 1223.

Alternatively, the base plate 1223, the first support seat 1224, and the second support seat 1225 may be integrally formed, i.e., the support seat 122 may be a unitary piece. It is understood that in other embodiments, the base plate 1223 may have other suitable configurations.

The shaft hole is located between the first support base 1224 and the second support base 1225 in the first predetermined direction (left-right direction). As an example, the first support seat 1224 is located at the left side of the shaft hole, and the second support seat 1225 is located at the right side of the shaft hole.

Wherein the shaft bracket 121 has a first end 1211 (left end) and a second end 1212 (right end) opposite in the first preset direction. The first end 1211 of the axle bracket 121 is supported on the first support base 1224 and the second end 1212 of the axle bracket 121 is supported on the second support base 1225. Thus, the axle bracket 121 is mounted on the support base 122. The support base 122 thus functions to support the shaft bracket 121.

As an example, as shown in fig. 1, the pedestal 121 includes a cylindrical portion 1213, a first connecting portion 1214, and a second connecting portion 1215. The cylindrical portion 1213 has the shaft hole. The central axis of the cylindrical portion 1213 (i.e., the axis of the rotating shaft 110) extends in the front-rear direction. The first connection part 1214 is located at and connected to the left side of the cylinder part 1213, and the second connection part 1215 is located at and connected to the right side of the cylinder part 1213.

For example, a first end (right end) of the first connecting portion 1214 is continuous with the outer circumferential surface of the cylindrical portion 1213, and a first end (left end) of the second connecting portion 1215 is continuous with the outer circumferential surface of the cylindrical portion 1213. The second end (left end 1211 of the axle bracket 121) of the first connecting portion 1214 is supported on the first end surface 1226 of the first support seat 1224, and the second end (right end 1212 of the axle bracket 121) of the second connecting portion 1215 is supported on the second end surface 1227 of the second support seat 1225.

Specifically, the top surface (upper surface) of the first support base 1224 is an end surface of the first support base 1224, which is far from the bottom plate 1223 in the second preset direction (up-down direction), and is referred to as a first end surface 1226. The top surface (upper surface) of the second support base 1225 is an end surface of the second support base 1225 away from the bottom plate 1223 in the second predetermined direction (up-down direction), and the end surface is referred to as a second end surface 1227.

Preferably, the first connecting portion 1214 is horizontally flush with the second connecting portion 1215. A portion of the first end face 1226 that contacts the second end of the first connection portion 1214 and a portion of the second end face 1227 that contacts the second end of the second connection portion 1215 are flush in the horizontal direction, that is, a portion of the first end face 1226 that contacts the second end of the first connection portion 1214 and a portion of the second end face 1227 that contacts the second end of the second connection portion 1215 are in the same horizontal plane.

Further, the steering apparatus 100 further includes a first fastening member 141 and a second fastening member 142. The first fastener 141 is used for mounting the first end 1211 of the axle bracket 121 on the first support seat 1224, and the second fastener 142 is used for mounting the second end 1212 of the axle bracket 121 on the second support seat 1225. In the embodiment shown in fig. 1, the steering device 100 includes two first fastening members 141 and two second fastening members 142 to make the connection between the axle bracket 121 and the supporting seat 122 more stable. Alternatively, the first fastener 141 may be a screw or a bolt, and the second fastener 142 may be a screw or a bolt.

In one embodiment, as shown in fig. 5, the first support base 1224 has a first side 12241 (right side) and a second side 12242 (left side) opposite to each other in the first predetermined direction, and the first side 12241 is adjacent to the second support base 1225 opposite to the second side 12242 in the first predetermined direction. The first side surface 12241 is provided with a first mounting groove (not shown), and the first end 131 of the elastic member 130 is fitted in the first mounting groove to realize support. That is, the side of the first supporting seat 1224 adjacent to the second supporting seat 1225 is provided with the first mounting groove, and the first mounting groove cooperates with the first end 131 of the elastic element 130 to support the elastic element 130.

It can be appreciated that the above design configures the first supporting part 1221 on the first supporting seat 1224, more specifically, configures the first supporting part 1221 in the first installation groove of the first supporting seat 1224, and the first supporting part 1221 is located at a side of the first supporting seat 1224 adjacent to the second supporting seat 1225. It can also be said that the first supporting portion 1221 is located at a side of the first supporting seat 1224 close to the rotating shaft 110, so that the first end 131 of the elastic element 130 can be stably and reasonably supported on the first supporting seat 1124.

Similar to the first supporting seat 1224, the second supporting seat 1225 has a third side and a fourth side opposite to each other in the first predetermined direction, the third side is adjacent to the first supporting seat opposite to the fourth side in the first predetermined direction, wherein a second mounting groove (not shown) is formed in the third side, and the second end 132 of the elastic member 130 is fitted in the second mounting groove to realize the supporting. The above design provides the second support portion 1222 on the second support base 1225 such that the second end 132 of the elastic element 130 is supported on the second support base 1225.

It will be appreciated that the first mounting slot is located below the first end surface 1226 of the first support seat 1224 and the second mounting slot is located below the second end surface 1227 of the second support seat 1225. Thus, the first end 1211 of the shaft bracket 121 is positioned above the first end 131 of the elastic member 130, and the second end 1212 of the shaft bracket 121 is positioned above the second end 132 of the elastic member 130. So that the axle bracket 121 does not affect the deformation of the elastic member 130 and the structure of the steering apparatus 100 of this embodiment is more rational.

By providing the first mounting groove on the first support seat 1224 and the second mounting groove on the second support seat 1225, the axle bracket 121 and the elastic element 130 are both disposed on the first support seat 1224 and the second support seat 1225, thereby simplifying the structure of the support seat 122 and further simplifying the structure of the steering apparatus 100.

In another embodiment, as shown in fig. 5, the first end face 1226 is configured with a first step portion comprising a first step face 1228 and a second step face 1229. The first step surface and the second step surface 1229 are both horizontal surfaces. The second step surface 1229 is located between the first step surface and the bottom plate 1223 in the second predetermined direction (up-down direction). That is, the second step surface 1229 is located below the first step surface. The first end 1211 of the pedestal 121 is supported on the first step surface. The first end 131 of the elastic member 130 is supported on the second step surface 1229. In other words, the first end 1211 of the shaft bracket 121 and the first end 131 of the elastic member 130 are supported on the first end surface 1226.

A second step portion is configured on the second end face 1227, the second step portion includes a third step surface and a fourth step surface, the third step surface and the fourth step surface are both horizontal surfaces, and the fourth step surface is located below the third step surface. The second end 1212 of the shaft holder 121 is supported on the third step surface, and the second end 132 of the elastic member 130 is supported on the fourth step surface. In other words, the second end 1212 of the pedestal 121 and the second end 132 of the resilient member 130 are both supported on the second end face 1227.

Thus, the axle bracket 121 and the elastic element 130 are mounted on the first support seat 1224 and the second support seat 1225. As shown in fig. 1, the elastic member 130 is supported on the upper surfaces of the first support seat 1224 and the second support seat 1225, so that the elastic member 130 and the bottom plate 1223 have a certain interval therebetween in the vertical direction, and the interval provides a certain deformation space for deformation of the elastic member 130. Compared with the technical scheme that the base needs to be provided with the rotating shaft installation groove and the avoidance groove capable of allowing the elastic piece 130 to deform in the related art, the steering device 100 of the embodiment has the advantages of more reasonable and simple structure and simpler and more convenient processing process.

Preferably, the first step surface and the third step surface are flush in the up-down direction, and the second step surface 1229 and the fourth step surface 1229 are flush in the up-down direction, so that the structure of the steering apparatus 100 is more rational.

In some embodiments, as shown in fig. 2, the rotation shaft 110 has a mounting groove 111, the mounting groove 111 penetrates the rotation shaft 110 in a first preset direction (left-right direction), and a first end (lower end) of the mounting groove 111 adjacent to the bottom plate 1223 in a second preset direction (up-down direction) is opened. That is, the first portion of the rotation shaft 110 is opposite to the elastic member 130 in the second preset direction, and a lower portion of the first portion of the rotation shaft 110 may be removed to form the mounting groove 111.

The cylindrical portion 1213 has an avoidance groove 1216, the avoidance groove 1216 penetrates the cylindrical portion 1213 in the first preset direction, and a first end (lower end) of the avoidance groove 1216 adjacent to the bottom plate 1223 in the second preset direction is open. In other words, the first portion of the cylindrical portion 1213 is opposed to the elastic member 130 in the second preset direction, and a lower portion of the first portion of the cylindrical portion 1213 may be removed to form the escape groove 1216.

As will be understood by those skilled in the art, since the cylindrical portion 1213 has an axial hole, the cylindrical portion 1213 is substantially annular. The escape groove 1216 thus penetrating the cylindrical portion 1213 in the first preset direction includes two sub-escape grooves each of which is open at an end adjacent to the bottom plate 1223 in the second preset direction.

As shown in fig. 6, the avoiding groove 1216 is opposite to the mounting groove 111 in the second predetermined direction, and a bottom wall surface 12161 of the avoiding groove 1216 is not lower than the bottom wall surface 1111 of the mounting groove 111. The bottom wall surface 12161 of the escape groove 1216 is a wall surface of the escape groove 1216 opposing the first portion thereof in the second predetermined direction, and the bottom wall surface 1111 of the mounting groove 111 is a wall surface of the mounting groove 111 opposing the first portion thereof in the second predetermined direction.

The first portion of the resilient member 130 fits within the mounting groove 111 through (and through) the relief groove 1216. The purpose of the mounting groove 111 is to enable the elastic member 130 to interact with the rotating shaft 110, the escape groove 1216 is to allow the elastic member 130 to pass through so that the engagement of the elastic member 130 with the rotating shaft 110 and the deformation of the elastic member 130 are not hindered by the cylindrical portion 1213, and the escape groove 1216 functions to escape the elastic member 130.

In the embodiment shown in fig. 2, the mounting groove 111 is located at the bottom of the rotation shaft 110. The escape groove 1216 is located at the bottom of the cylindrical portion 1213. The bottom wall 1111 of the mounting groove 111 is a plane, and after the first portion of the elastic member 130 is fitted into the mounting groove 111, the upper surface of the first portion of the elastic member 130 is in contact with the bottom wall 1111 of the mounting groove 111.

Alternatively, the elastic member 130 is made of a plate-shaped material having elasticity, and the length direction of the elastic member 130 is in the left-right direction. The elastic member 130 has a second portion, a first portion and a third portion connected in sequence. The first portion of the elastic member 130 is a middle portion, the second portion is located at the left side of the first portion, and the third portion is located at the right side of the first portion. The right end of the second portion is connected to the first portion, the left end of the second portion is a free end, the free end is the first end 131 of the elastic member 130, the left end of the third portion is connected to the first portion, the right end of the second portion is a free end, and the free end is the second end 132 of the elastic member 130.

It should be noted that the rotation-deformation matching structure between the rotating shaft 110 and the elastic member 130 is not limited to the structure of the above specific embodiment, and a reasonable structure that the rotation of the rotating shaft 110 can drive the elastic member 130 to deform all belongs to the protection scope of the present invention.

As shown in fig. 2, the length of the escape groove 1216 in the axial direction of the rotating shaft 110 and the length of the mounting groove 111 in the axial direction of the rotating shaft 110 are equal to each other, so that the escape groove 1216 and the mounting groove 111 better correspond to each other, and the structure of the steering apparatus 100 is also more reasonable. Further, the width direction of the plate-shaped elastic member 130 is the axial direction of the rotating shaft 110, and the width of the elastic member 130 and the length of the mounting groove 111 in the axial direction of the rotating shaft 110 are equal to each other, so that the elastic member 130 and the mounting groove 111 are better adapted, and the structural rationality is improved.

Further, the supporting base 122 further includes a stopper 123. As shown in fig. 2, the stopper 123 is provided on the upper surface of the base plate 1223. The limiting member 123 is located below the elastic member 130, and the limiting member 123 is spaced from the (undeformed) elastic member 130 by a predetermined distance in a second predetermined direction so as to limit the deformation degree of the elastic member 130.

Specifically, when the elastic member 130 is deformed in the gap, the elastic member 130 does not contact the limiting member 123, so that the limiting member 123 does not limit the deformation of the elastic member 130. As the deformation degree of the elastic member 130 increases, the distance between the deformed elastic member 130 and the limiting member 123 in the second predetermined direction gradually decreases until the bottom of the elastic member 130 contacts the limiting member 123, and the limiting member 123 limits the elastic member 130 to continue to deform. Therefore, the position of the position-limiting member 123 defines the maximum deformation degree of the elastic member 130.

Specifically, as shown in fig. 1, the elastic element 130 has three supporting positions with the rotating shaft 110 and the supporting seat 122: a supporting position between the first portion of the elastic member 130 and the bottom wall 1111 of the mounting groove 111, a supporting position between the first end 131 of the elastic member 130 and the first supporting portion 1221, and a supporting position between the second end 132 of the elastic member 130 and the second supporting portion 1222. For example, when the rotation shaft 110 rotates counterclockwise, a portion of the bottom wall surface 1111 of the mounting groove 111, which is located on the left side of the central axis of the rotation shaft 110 in the left-right direction, abuts against the upper surface of the first portion of the elastic member 130 and applies pressure, so that the second portion of the elastic member 130 is deformed. When the second portion is deformed to a certain extent, the second portion contacts the stopper 123 to limit the continuous deformation of the second portion. Since the elastic member 130 has elasticity, the deformed elastic member 130 can apply a restoring force to the rotation shaft 110, and the restoring force causes the rotation shaft 110 to tend to return to an original state, i.e., a position state of the rotation shaft 110 when the elastic member 130 is not deformed.

As an example, as shown in fig. 1, the limiting member 123 has a fifth side surface 1231 and a sixth side surface 1232 opposite to each other in the first predetermined direction, and the central axis of the rotating shaft 110 is located between the fifth side surface 1231 and the sixth side surface 1232 in the first predetermined direction.

The first portion of the elastic member 130 is located between the fifth side 1231 and the sixth side 1232 in the first predetermined direction. The above design enables the stopper 123 to better contact the bottom surface of the second portion of the deformed elastic member 130 and also better contact the bottom surface of the third portion of the deformed elastic member 130, so that the structure of the steering apparatus 100 is more reasonable.

Specifically, the position of the stopper 123 that can contact the bottom surface of the second portion of the deformed elastic member 130 is a position where the fifth side surface 1231 of the stopper 123 intersects the top surface 1233 of the stopper 123 as shown in fig. 6, and the position of the stopper 123 that can contact the bottom surface of the third portion of the deformed elastic member 130 is a position where the sixth side surface 1232 of the stopper 123 intersects the top surface 1233 of the stopper 123 as shown in fig. 6.

An embodiment of another aspect of the present invention provides a balance car, which includes the steering device 100 in any one of the above embodiments of the present invention. The balance car also comprises a steering rod. The steering rod is connected to the rotating shaft 110. When a user rotates the steering rod, the steering rod drives the rotating shaft 110 to rotate, the rotating shaft 110 rotates to drive the elastic member 130 to deform, and the rotating shaft 110 can drive the steering rod to reset while the elastic member 130 provides restoring force for the rotating shaft 110.

In some embodiments, the balance car further comprises a car body, optionally, the steering device 100 is a part of the car body, and the steering rod is connected with the rotating shaft 110 to realize the installation with the car body.
