[0049] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0050] Reference below Figures 1-8 A steering device 100 of a vehicle and a vehicle according to an embodiment of the present invention are described. The steering device 100 is used to convert a driver's steering intention into a steering action of a wheel, thereby achieving control of the vehicle's driving direction.
[0051] like Figures 1-8 As shown, the steering device 100 according to an embodiment of the present utility model includes: a first core shaft 10 and a second core shaft 20, the first core shaft 10 and the second core shaft 20 are transmission-connected to drive the second core shaft 20 to rotate, and the first core shaft 10 and the second core shaft 20 are arranged along the first direction; a fixing mechanism 30, the fixing mechanism 30 is used to be fixedly connected to the body of the vehicle, the fixing mechanism 30 includes a first body 31, the first body 31 defines a mounting hole 310, at least part of the first core shaft 10 is assembled in the mounting hole 310, the first body 31 is formed with a notch 3101 communicating with the mounting hole 310, and the mounting hole 310 and the notch 3101 both extend along the first direction; the fixing mechanism 30 also includes an adjusting assembly 32 and a positioning block 33, the positioning block 33 is assembled in the notch 3101, the adjusting assembly 32 is penetrated by the first body 31 and the positioning block 33 to fix the positioning block 33 and the first body 31, and along the first direction, the positioning block 33 is arranged near the upper end of the first body 31.
[0052] The first direction is Figure 1 In the X direction, the first core shaft 10 includes an upper core shaft 11 and an upper column tube 12. The upper core shaft 11 is passed through the upper column tube 12, and the upper core shaft 11 and the upper column tube 12 can be connected by a deep groove ball bearing, so that the upper core shaft 11 can rotate relative to the upper column tube 12. Furthermore, a spring retaining ring is arranged between the upper core shaft 11 and the upper column tube 12, and the spring retaining ring can limit the upper core shaft 11 from moving relative to the upper column tube 12 along the first direction. The upper core shaft 11 and the second core shaft 20 in the first core shaft 10 are connected in a transmission manner to drive the second core shaft 20 to rotate. Specifically, the upper core shaft 11 and the second core shaft 20 can be connected in a transmission manner through a spline structure to drive the second core shaft 20 to rotate. The spline structure can also enable the upper core shaft 11 and the second core shaft 20 to move relative to each other along a first direction. The other end of the upper core shaft 11 away from the second core shaft 20 is connected to the steering wheel of the vehicle, and the other end of the second core shaft 20 is connected to the steering gear of the vehicle. When the driver turns the steering wheel to drive the upper core shaft 11 to rotate, the spline structure will drive the second core shaft 20 to rotate synchronously, thereby achieving torque transmission and further achieving control of the vehicle's driving direction. Further, when the vehicle collides, the first core shaft 10 is unlocked, the steering device 100 will collapse, and the upper core shaft 11 and the second core shaft 20 can generate axial displacement through the spline structure, so that the upper core shaft 11 can slide downward relative to the second core shaft 20 when subjected to impact force, thereby achieving a collapse effect.
[0053] It can be explained that the spline structure fitting length between the upper core shaft 11 and the second core shaft 20 should be greater than the collapse distance to avoid jamming or interference between the upper core shaft 11 and the second core shaft 20 during the collapse process. It can also ensure that the steering device 100 can collapse in a predetermined manner during a collision, thereby achieving the best collapse effect. In addition, the increase in the spline structure fitting length helps to disperse and absorb the impact force generated by the collision, thereby reducing damage to the driver.
[0054] The fixing mechanism 30 includes: a first body 31, which can be an outer column tube. The first body 31 defines a mounting hole 310, and the fixing mechanism 30 is used to be fixedly connected to the vehicle body. For example, the fixing mechanism 30 and the vehicle body can be fixedly connected by bolts, or the fixing mechanism 30 and the vehicle body can be fixedly connected by welding, but the utility model is not limited to this. The fixing mechanism 30 and the vehicle body can also be fixedly connected by other means, as long as the fixing mechanism 30 is used to be fixedly connected to the vehicle body.
[0055] The first core shaft 10 and the second core shaft 20 are arranged along the first direction, and at least a portion of the first core shaft 10 is assembled in the mounting hole 310. For example, one-half, one-third, or other proportions of the first core shaft 10 can be assembled in the mounting hole 310, but the present invention is not limited thereto. The first core shaft 10 can also have other proportions of portions assembled in the mounting hole 310, as long as at least a portion of the first core shaft 10 is assembled in the mounting hole 310. Specifically, the upper column tube 12 of the first core shaft 10 extends into the mounting hole 310, and the upper core shaft 11 is mounted in the upper column tube 12. The size of the mounting hole 310 is adjustable to lock or unlock the first core shaft 10. For example, the fixing mechanism 30 can be clamped by a clamping device to reduce the size of the mounting hole 310 to lock the first core shaft 10, so that the first core shaft 10 can be stably located in the fixed position to ensure that the steering device 100 remains stable and reliable under normal working conditions. When the clamping device releases the fixing mechanism 30 , the size of the mounting hole 310 is restored to unlock the first spindle 10 .
[0056] The first body 31 is formed with a notch 3101 that communicates with the mounting hole 310. Both the mounting hole 310 and the notch 3101 extend along the first direction. The formation of the notch 3101 makes it easier for the first body 31 to deform when subjected to force, allowing the first body 31 to more closely fit the surface of the first core shaft 10, thereby improving the clamping effect and holding force. The notch 3101 also serves as a stress concentration buffer area, alleviating stress concentration in the first body 31, thereby reducing the risk of damage to the first body 31 due to stress concentration and helping to extend the service life of the first body 31. It can be explained that the size of the notch 3101 can be reasonably set according to actual conditions to ensure that the first body 31 can meet deformation requirements without weakening the overall strength and rigidity of the first body 31.
[0057] The fixing mechanism 30 also includes an adjustment component 32 and a positioning block 33. The adjustment component 32 can be a mechanical adjustment component 32, an electrical adjustment component 32, etc. The positioning block 33 is assembled in the notch 3101. The adjustment component 32 is passed through the first body 31 and the positioning block 33 to fix the positioning block 33 and the first body 31. The positioning block 33 can be made of nylon material. The nylon material has a certain elasticity and can be deformed when subjected to external force, and can quickly return to its original shape after the external force is removed, so that when the first body 31 is clamped, the positioning block 33 can be quickly deformed, thereby achieving the effect of the first body 31 clamping the first core shaft 10, and can also enhance the clamping effect of the first body 31 on the first core shaft 10, and can also absorb and disperse the stress and impact generated during the clamping process to protect other components from damage.
[0058] Along the first direction, the positioning block 33 is arranged close to the upper end of the first body 31. It can be explained that the upper end of the first body 31 is the end of the first body 31 close to the steering wheel, and the lower end of the first body 31 is the end of the first body 31 away from the steering wheel. Such an arrangement can reduce the impact of vehicle collision on the breaking force of the positioning block 33, and the positioning block 33 has better breaking force performance than the existing rivets. The positioning block 33 can quickly return to its original shape after deformation, which can reduce the difference in breaking force of different batches of steering devices 100 and improve the performance of the vehicle.
[0059] Moreover, compared with the prior art, when the first core shaft 10 is locked, there is no need to provide a crushing structure and a pull-off block structure. This can provide sufficient support and holding force for the steering device 100, thereby ensuring that the steering device 100 remains stable and reliable under normal working conditions, so that the driver can accurately and stably control the steering wheel and achieve smooth steering of the vehicle. This simplifies the structure of the steering device 100, and further reduces the production cost of the steering device 100 while satisfying the holding force of the steering device 100. Furthermore, by adjusting the size of the mounting hole 310, the first core shaft 10 can be unlocked, making it easier to disassemble and assemble the steering device 100. In addition, when the vehicle collides, by unlocking the first core shaft 10, the first core shaft 10 can be allowed to displace in the first direction, thereby absorbing the collision energy and reducing the impact on the driver.
[0060] According to the steering device 100 of the vehicle according to the embodiment of the present invention, a mounting hole 310 is formed through the first body 31, and the first core shaft 10 and the second core shaft 20 are arranged along the first direction. At least a part of the first core shaft 10 is assembled in the mounting hole 310. There is no need to additionally set up a crushing structure and a pull-off block structure, which can provide sufficient holding force for the steering device 100, thereby ensuring that the steering device 100 has sufficient stability, so that the driver can accurately and stably control the steering wheel and realize smooth steering of the vehicle, thereby reducing the production cost of the steering device 100 while satisfying the holding force of the steering device 100.
[0061] Furthermore, the adjustment assembly 32 is provided through the first body 31 and the positioning block 33 to secure the positioning block 33 to the first body 31. The positioning block 33 is deformable when subjected to an external force and quickly returns to its original shape after the external force is removed. This allows the positioning block 33 to deform rapidly when the first body 31 is clamped, thereby enabling the first body 31 to clamp the first mandrel 10. This also enhances the clamping effect of the first body 31 on the first mandrel 10 and absorbs and disperses the stress and impact generated during the clamping process, protecting other components from damage. Along the first direction, the positioning block 33 is disposed near the upper end of the first body 31, which can reduce the impact of vehicle collisions on the breaking force of the positioning block 33. Furthermore, the positioning block 33 exhibits better breaking force than existing rivets and quickly returns to its original shape after deformation, reducing the variability in breaking force between different batches of steering devices 100 and improving vehicle performance.
[0062] According to some embodiments of the present invention, Figure 1 As shown, the first body 31 has a first wall portion 311 and a second wall portion 312 relative to each other, the mounting hole 310 is located between the first wall portion 311 and the second wall portion 312, and the adjustment component 32 is assembled with the first wall portion 311 and the second wall portion 312. The adjustment component 32 is used to drive the first wall portion 311 and the second wall portion 312 closer or farther away to adjust the size of the mounting hole 310.
[0063] The first body 31 may be an outer column tube. The first body 31 defines a mounting hole 310. The first body 31 has a first wall portion 311 and a second wall portion 312 that oppose each other. The first wall portion 311 and the second wall portion 312 collectively define the mounting hole 310. The mounting hole 310 is located between the first wall portion 311 and the second wall portion 312. The adjustment assembly 32 cooperates with and is assembled with the first wall portion 311 and the second wall portion 312. The adjustment assembly 32 is used to drive the first wall portion 311 and the second wall portion 312 closer together or further apart to adjust the size of the mounting hole 310. Specifically, the adjustment assembly 32 may be a clamping device, or a locking nut and a locking screw threadedly connected to form the adjustment assembly 32. The clamping device may be used to clamp or loosen the first wall portion 311 and the second wall portion 312 to move the first wall portion 311 and the second wall portion 312 closer together or further apart, thereby adjusting the size of the mounting hole 310. Alternatively, a locking screw may be provided through the first wall portion 311 and the second wall portion 312, and a locking nut may be threadedly connected to the locking screw. By tightening or loosening the locking nut, the first wall portion 311 and the second wall portion 312 can be moved closer or further away, thereby adjusting the size of the mounting hole 310.
[0064] Furthermore, when the first wall portion 311 and the second wall portion 312 are far apart, the size of the mounting hole 310 can be increased so that the first core shaft 10 can be smoothly assembled in the mounting hole 310. When the first wall portion 311 and the second wall portion 312 are close to each other, the size of the mounting hole 310 can be reduced so that the first body 31 can tightly embrace the first core shaft 10, thereby providing sufficient support and holding force for the steering device 100 to ensure that the steering device 100 remains stable and reliable under normal working conditions, thereby reducing the risk of loosening or falling off due to vibration or impact. In addition, such a setting can make the entire steering device 100 compact in structure and occupy a small space, which is beneficial to the layout and installation of the steering device 100 on the vehicle, and can also eliminate the setting of the crushing structure and the pull-off block structure to reduce the production cost of the steering device 100.
[0065] According to some embodiments of the present invention, Figure 1 As shown, along the circumference of the mounting hole 310, one end of the first wall portion 311 and the corresponding end of the second wall portion 312 are spaced apart to form a gap 3101 connected to the mounting hole 310; and / or, the other end of the first wall portion 311 and the corresponding end of the second wall portion 312 are spaced apart to form a gap 3101 connected to the mounting hole 310.
[0066] As one example of the present application, one end of the first wall portion 311 and the corresponding end of the second wall portion 312 are spaced apart to form a notch 3101 communicating with the mounting hole 310, or the other end of the first wall portion 311 and the corresponding end of the second wall portion 312 are spaced apart to form a notch 3101 communicating with the mounting hole 310. As another example of the present application, one end of the first wall portion 311 and the corresponding end of the second wall portion 312 are spaced apart to form a notch 3101 communicating with the mounting hole 310, and the other end of the first wall portion 311 and the corresponding end of the second wall portion 312 are spaced apart to form a notch 3101 communicating with the mounting hole 310. It is sufficient as long as the first wall portion 311 and the second wall portion 312 are spaced apart along the circumference of the mounting hole 310 to form the notch 3101 communicating with the mounting hole 310. The formation of the notch 3101 can make the first wall portion 311 and the second wall portion 312 more easily deformed when subjected to force, so that the first body 31 can fit more closely to the surface of the first core shaft 10, thereby improving the clamping effect and holding force. The notch 3101 can also serve as a buffer area for stress concentration, which can reduce the stress concentration of the first wall portion 311 and the second wall portion 312, thereby reducing the risk of damage to the first wall portion 311 and the second wall portion 312 due to stress concentration, and helping to extend the service life of the first body 31.
[0067] It can be explained that the size of the notch 3101 can be reasonably set according to actual conditions to ensure that the first body 31 can meet the deformation requirements without weakening the overall strength and rigidity of the first body 31.
[0068] According to some embodiments of the present invention, Figure 1 As shown, one end of the first wall portion 311 is connected to the corresponding end of the second wall portion 312 , and the other end of the first wall portion 311 is spaced apart from the corresponding end of the second wall portion 312 to form a gap 3101 .
[0069] Among them, one end of the first wall portion 311 and the corresponding end of the second wall portion 312 are connected, for example: one end of the first wall portion 311 and the corresponding end of the second wall portion 312 can be welded together, or the first wall portion 311 and the second wall portion 312 can be integrally formed, but the utility model is not limited to this. One end of the first wall portion 311 and the corresponding end of the second wall portion 312 can also be fixedly connected by other means, as long as one end of the first wall portion 311 and the corresponding end of the second wall portion 312 are connected.
[0070] As an example of the present application, the first wall portion 311 and the second wall portion 312 can be integrally formed to define a cylindrical first body 31, and the other end of the first wall portion 311 and the corresponding end of the second wall portion 312 are spaced apart to form a notch 3101. Such a configuration can not only ensure the overall strength and rigidity of the first body 31, so that the first body 31 remains stable when subjected to the torque generated when the steering device 100 is working, but also facilitate the deformation of the first body 31, making the first wall portion 311 and the second wall portion 312 more likely to deform, so that the first body 31 can fit more closely to the surface of the first core shaft 10, thereby enhancing the clamping effect and holding force.
[0071] According to some embodiments of the present invention, Figure 1 As shown, the first body 31 may further include a third wall portion 313 , which is connected between one end of the first wall portion 311 and a corresponding end of the second wall portion 312 .
[0072] The third wall portion 313 is connected between one end of the first wall portion 311 and the corresponding end of the second wall portion 312. For example, the third wall portion 313 and the first wall portion 311 and the second wall portion 312 can be fixedly connected by welding, or the third wall portion 313, the first wall portion 311, and the second wall portion 312 can be integrally formed. However, the present invention is not limited thereto. The third wall portion 313 and the first wall portion 311 and the second wall portion 312 can also be fixedly connected by other means, as long as the third wall portion 313 is connected between one end of the first wall portion 311 and the corresponding end of the second wall portion 312. By connecting the third wall portion 313 between one end of the first wall portion 311 and the corresponding end of the second wall portion 312, a stable rigid connection can be formed, which further improves the overall strength and rigidity of the first body 31, and thus further improves the stability and reliability of the first body 31.
[0073] According to some embodiments of the present invention, Figure 1 As shown, the third wall portion 313 and the notch 3101 can be arranged relative to each other, so that the first body 31 can form a balanced stress distribution when subjected to force, which helps to reduce the risk of deformation or damage caused by local stress concentration, thereby effectively extending the service life of the steering device 100.
[0074] According to some embodiments of the present invention, Figure 1 As shown, the first body 31 can also have a fourth wall portion 314. Along the first direction, the fourth wall portion 314 is arranged at one end of the mounting hole 310, and the fourth wall portion 314 is fixedly connected to the first wall portion 311 and the second wall portion 312. The second core shaft 20 is passed through the fourth wall portion 314 to extend into the mounting hole 310, and the second core shaft 20 is rotatably arranged on the fourth wall portion 314.
[0075] Among them, along the first direction, the fourth wall portion 314 is arranged at one end of the mounting hole 310, and the fourth wall portion 314 is located at the end of the first body 31 away from the first core shaft 10, and the fourth wall portion 314 can also be connected to the third wall portion 313, and the fourth wall portion 314 is fixedly connected to the first wall portion 311, the second wall portion 312 and the third wall portion 313. For example, the fourth wall portion 314 and the first wall portion 311, the second wall portion 312 and the third wall portion 313 can be fixedly connected by welding, or the fourth wall portion 314, the first wall portion 311, the second wall portion 312 and the third wall portion 313 can be integrally formed, but the utility model is not limited to this. The fourth wall portion 314 and the first wall portion 311, the second wall portion 312 and the third wall portion 313 can also be fixedly connected by other means, as long as the fourth wall portion 314 is fixedly connected to the first wall portion 311, the second wall portion 312 and the third wall portion 313. Such a configuration can further increase the strength and rigidity of the first body 31 , thereby further reducing the risk of damage to the first body 31 .
[0076] The second core shaft 20 is passed through the fourth wall portion 314 to extend into the mounting hole 310, and the second core shaft 20 is rotatably provided on the fourth wall portion 314. The second core shaft 20 and the fourth wall portion 314 can be rotatably connected by a bearing. For example, the second core shaft 20 and the fourth wall portion 314 can be rotatably connected by a deep groove ball bearing. Specifically, the fourth wall portion 314 is formed with an assembly hole connected to the mounting hole 310, and the deep groove ball bearing is interference fit into the assembly hole, and the second core shaft 20 is passed through the inner ring of the deep groove ball bearing. The design of the deep groove ball bearing allows the second core shaft 20 to rotate freely in its inner ring, so that the second core shaft 20 is rotatably provided on the fourth wall portion 314. By rotating the second core shaft 20, the steering angle of the wheel can be controlled, thereby realizing the steering of the vehicle.
[0077] According to some embodiments of the present invention, Figure 1 As shown, the adjustment assembly 32 is assembled with the first wall portion 311 and the second wall portion 312 to drive the first wall portion 311 and the second wall portion 312 to move closer or farther away.
[0078] Among them, the adjustment component 32 can be a mechanical adjustment component 32, an electrical adjustment component 32, etc. The adjustment component 32 can be a combination of the above-mentioned locking screw and locking nut. By passing the locking screw through the first wall portion 311 and the second wall portion 312, and having the locking nut threadedly connected to the locking screw, the adjustment component 32 can be assembled with the first wall portion 311 and the second wall portion 312. By tightening or loosening the locking nut, the first wall portion 311 and the second wall portion 312 can be moved closer or further away, thereby adjusting the size of the mounting hole 310. When the first wall portion 311 and the second wall portion 312 are moved away from each other, the size of the mounting hole 310 can be increased, so that the first core shaft 10 can be smoothly assembled in the mounting hole 310, and the first core shaft 10 can be moved relative to the first body 31 along the first direction. When the first wall portion 311 and the second wall portion 312 are close to each other, the size of the mounting hole 310 can be reduced so that the first body 31 can hold the first core shaft 10 tightly, thereby providing sufficient support and holding force for the steering device 100 to ensure that the steering device 100 remains stable and reliable under normal working conditions, thereby reducing the risk of loosening or falling off due to vibration or impact. In addition, such a setting can make the entire steering device 100 compact in structure and occupy a small space, which is beneficial to the layout and installation of the steering device 100 on the vehicle and can reduce the production cost of the steering device 100.
[0079] According to some embodiments of the present invention, Figure 1As shown, the adjustment assembly 32 may include: an adjustment pin 320, a first adjustment block 321 and a second adjustment block 322, the first adjustment block 321 and the second adjustment block 322 are located on the side of the first wall portion 311 away from the second wall portion 312, the first adjustment block 321 and the second adjustment block 322 are opposite and adjacent to each other, the second adjustment block 322 is located between the first adjustment block 321 and the first wall portion 311, the adjustment pin 320 is provided through the first adjustment block 321, the second adjustment block 322, the first wall portion 311, the positioning block 33 and the second wall portion 312, and the adjustment pin 320 is provided through the first adjustment block 321, the second adjustment block 322, the first wall portion 311, the positioning block 33 and the second wall portion 312. 20 is provided with a first limiting portion 3201 and a second limiting portion 3202. The first limiting portion 3201 is located on a side of the first adjusting block 321 away from the second adjusting block 322 and abuts against the first adjusting block 321. The second limiting portion 3202 is located on a side of the second wall portion 312 away from the first wall portion 311 and cooperates with the second wall portion 312 to limit the position. The first adjusting block 321 and the second adjusting block 322 are rotated relative to each other to make the first adjusting block 321 and the second adjusting block 322 move closer to or farther away from each other, so that the first wall portion 311 and the second wall portion 312 move closer to or farther away from each other.
[0080] Among them, the adjusting pin 320 can be sequentially passed through the first adjusting block 321, the second adjusting block 322, the first wall portion 311, the positioning block 33 and the second wall portion 312, and the adjusting pin 320 can be provided with a first limiting portion 3201 and a second limiting portion 3202. For example, the adjusting pin 320 and the first limiting portion 3201 and the second limiting portion 3202 can be fixedly connected by welding, or the adjusting pin 320 and the first limiting portion 3201 and the second limiting portion 3202 can be fixedly connected by threads, but the utility model is not limited to this. The adjusting pin 320 and the first limiting portion 3201 and the second limiting portion 3202 can also be fixedly connected by other means, as long as the adjusting pin 320 is provided with a first limiting portion 3201 and a second limiting portion 3202.
[0081] The first limiting portion 3201 is located on the side of the first adjustment block 321 away from the second adjustment block 322 and abuts against the first adjustment block 321, and the second limiting portion 3202 is located on the side of the second wall portion 312 away from the first wall portion 311 and cooperates with the second wall portion 312 to limit the first wall portion 311 and the second wall portion 312, so that the first wall portion 311 and the second wall portion 312 can be limited between the first limiting portion 3201 and the second limiting portion 3202, which can effectively prevent the first wall portion 311 and the second wall portion 312 from excessive displacement or offset when subjected to external force, thereby ensuring the accuracy and consistency of the adjustment, and reducing the risk of overall structural failure due to local deformation.
[0082] By relative rotation of the first adjustment block 321 and the second adjustment block 322, the first adjustment block 321 and the second adjustment block 322 are brought closer or farther away, so that the first wall portion 311 and the second wall portion 312 are brought closer or farther away, thereby adjusting the size of the mounting hole 310. When the first adjustment block 321 and the second adjustment block 322 are relatively rotated to move the first adjustment block 321 and the second adjustment block 322 away from each other, the first wall portion 311 and the second wall portion 312 are deformed and brought closer together, thereby reducing the size of the mounting hole 310, so that the first body 31 can hold the first core shaft 10 tightly, thereby providing sufficient support and holding force for the steering device 100, to ensure that the steering device 100 remains stable and reliable under normal working conditions, thereby reducing the risk of loosening or falling off due to vibration or impact, thereby improving the safety and reliability of the steering device 100. When the first adjustment block 321 and the second adjustment block 322 rotate relative to each other so that the first adjustment block 321 and the second adjustment block 322 are close to each other, the first wall portion 311 and the second wall portion 312 are separated from each other, so that the size of the mounting hole 310 can be restored, and the first core shaft 10 can be moved relative to the first body 31 along the first direction.
[0083] According to some embodiments of the present invention, Figure 8 As shown, the end surface of the first adjustment block 321 facing the second adjustment block 322 has a first adjustment surface 3210, and the end surface of the second adjustment block 322 facing the first adjustment block 321 has a second adjustment surface 3220 spaced apart from the first adjustment surface 3210. The first adjustment surface 3210 is formed with a plurality of first bosses 3211, and the plurality of first bosses 3211 are arranged in sequence along the circumferential direction of the first adjustment block 321. The first adjustment surface 3210 has a plurality of first sub-adjustment surfaces, and the plurality of first sub-adjustment surfaces are respectively located between two adjacent first bosses 3211. The second adjustment surface 3220 is formed with a plurality of second bosses 3221, and the plurality of second bosses 3221 are arranged in sequence along the circumferential direction of the second adjustment block 322. The second adjustment surface 3220 has a plurality of second sub-adjustment surfaces, and the plurality of second sub-adjustment surfaces are respectively located between two adjacent second bosses 3221. The first boss 3211 is assembled between the corresponding two second bosses 3221 and abuts against the second sub-adjustment surface. The second boss 3221 is assembled between the corresponding two first bosses 3211 and abuts against the first sub-adjustment surface.
[0084] A first sub-adjustment surface is provided between any two adjacent first bosses 3211, and a second sub-adjustment surface is provided between any two adjacent second bosses 3221. The first boss 3211 is mounted between the corresponding two adjacent second bosses 3221 and abuts the second sub-adjustment surface, while the second boss 3221 is mounted between the corresponding two adjacent first bosses 3211 and abuts the first sub-adjustment surface. As an example, the first sub-adjustment surface can be configured as an inclined surface, and the second sub-adjustment surface can be configured as an inclined surface. When the first adjustment block 321 and the second adjustment block 322 rotate relative to each other, the first adjustment block 321 and the second adjustment block 322 can be moved closer to or further away from each other. Furthermore, the contact area between the first adjustment block 321 and the second adjustment block 322 can be increased, making the connection between the first adjustment block 321 and the second adjustment block 322 more secure, and facilitating stress dispersion, thereby avoiding damage caused by local stress concentration, thereby improving the stability and durability of the adjustment assembly 32.
[0085] According to some embodiments of the present invention, Figure 8 As shown, the first sub-adjustment surface includes a first locking surface 3212 and a first unlocking surface 3213 arranged along the circumferential direction of the first adjustment block 321. The first locking surface 3212 and the first unlocking surface 3213 are connected, and the first unlocking surface 3213 is located on the side of the first locking surface 3212 facing away from the second adjustment block 322. The second sub-adjustment surface includes a second locking surface 3222 and a second unlocking surface 3223 arranged along the circumferential direction of the second adjustment block 322. The second locking surface 3222 and the second unlocking surface 3223 are connected, and the second unlocking surface 3223 is located on the side of the second locking surface 3222 facing away from the first adjustment block 321.
[0086] The first locking surface 3212 and the first unlocking surface 3213 are arranged along the circumferential direction of the first adjustment block 321, and the second locking surface 3222 and the second unlocking surface 3223 are arranged along the circumferential direction of the second adjustment block 322. When the first adjustment block 321 rotates to make the first adjustment block 321 and the second adjustment block 322 move away from each other and lock, the first boss 3211 rotates toward the second locking surface 3222, and the first boss 3211 abuts against the second locking surface 3222. The first and second bosses 3221 face the first locking surface 3212, and the second boss 3221 abuts against the first locking surface 3212. When the first adjusting block 321 rotates to bring the first adjusting block 321 and the second adjusting block 322 close to each other and unlock, the first boss 3211 moves toward the second unlocking surface 3223, and the second boss 3221 faces the first unlocking surface 3213, thereby enabling the first adjusting block 321 and the second adjusting block 322 to be locked and unlocked.
[0087] According to some embodiments of the present invention, Figure 2As shown, the adjusting pin 320 is detachably connected to at least one of the first limiting portion 3201 and the second limiting portion 3202, for example: the adjusting pin 320 is detachably connected to the first limiting portion 3201, or the adjusting pin 320 is detachably connected to the second limiting portion 3202, or the adjusting pin 320 is detachably connected to both the first limiting portion 3201 and the second limiting portion 3202, as long as the adjusting pin 320 is detachably connected to at least one of the first limiting portion 3201 and the second limiting portion 3202. This application is described by taking the detachable connection between the adjusting pin 320 and the second limiting portion 3202 as an example. Specifically, the first limiting portion 3201 can be constructed as the pin head of the adjusting pin 320, the first limiting portion 3201 and the adjusting pin 320 can be integrally formed, the second limiting portion 3202 can be constructed as a locking nut, and the adjusting pin 320 and the second limiting portion 3202 are threadedly connected so that the adjusting pin 320 and the second limiting portion 3202 are detachably connected. Such a setting can facilitate users to adjust the position of the adjusting pin 320 according to actual needs, improve the flexibility of the adjusting pin 320, and when the second limiting part 3202 or the adjusting pin 320 is damaged, the second limiting part 3202 can be directly disassembled and the second limiting part 3202 or the adjusting pin 320 can be replaced, which can reduce the maintenance cost and time of the steering device 100.
[0088] According to some embodiments of the present invention, Figure 2 As shown, along the axial direction of the adjustment pin 320, at least one of the first limiting portion 3201 and the second limiting portion 3202 is adjustable relative to the adjustment pin 320. For example, the first limiting portion 3201 is adjustable relative to the adjustment pin 320, or the second limiting portion 3202 is adjustable relative to the adjustment pin 320, or both the first limiting portion 3201 and the second limiting portion 3202 are adjustable relative to the adjustment pin 320. As long as at least one of the first limiting portion 3201 and the second limiting portion 3202 is adjustable relative to the adjustment pin 320, the position of the adjustment pin 320 can be adjusted. This application takes the adjustable position of the second limiting portion 3202 relative to the adjustment pin 320 as an example for description. Specifically, the first limiting portion 3201 can be configured as the pin head of the adjusting pin 320. The first limiting portion 3201 and the adjusting pin 320 can be integrally formed. The second limiting portion 3202 can be configured as a locking nut. The adjusting pin 320 and the second limiting portion 3202 are threadedly connected to each other, so that the position of the second limiting portion 3202 relative to the adjusting pin 320 is adjustable. This arrangement allows the second limiting portion 3202 to move axially along the adjusting pin 320, making it convenient for the user to adjust the position of the second limiting portion 3202 according to actual needs, thereby adjusting the distance between the pin head and the second limiting portion 3202. This allows the adjusting pin 320 to adapt to first bodies 31 of different sizes, thereby improving the versatility of the adjusting pin 320.
[0089] According to some embodiments of the present invention, Figure 1As shown, at least one of the first adjustment block 321 and the second adjustment block 322 is fixedly provided with an adjustment arm 323, for example: the first adjustment block 321 is fixedly provided with the adjustment arm 323, or the second adjustment block 322 is fixedly provided with the adjustment arm 323, or both the first adjustment block 321 and the second adjustment block 322 are fixedly provided with the adjustment arm 323, as long as at least one of the first adjustment block 321 and the second adjustment block 322 is fixedly provided with the adjustment arm 323. This application takes the example of the first adjustment block 321 being fixedly provided with the adjustment arm 323 as an example for explanation. The first adjustment block 321 and the adjustment arm 323 can be fixedly connected by welding, or the first adjustment block 321 and the adjustment arm 323 can be integrally formed, but the present invention is not limited thereto. The first adjustment block 321 and the adjustment arm 323 can also be fixedly connected by other means, as long as the first adjustment block 321 is fixedly provided with the adjustment arm 323.
[0090] By rotating the adjusting arm 323, the first adjusting block 321 can be driven to rotate, thereby adjusting the distance between the first adjusting block 321 and the second adjusting block 322. Figure 1 As shown, the adjustment arm 323 rotates along direction A, which can drive the first adjustment block 321 to rotate, so that the first adjustment block 321 and the second adjustment block 322 are brought closer together, thereby bringing the first wall portion 311 and the second wall portion 312 closer together, thereby clamping the first wall portion 311 and the second wall portion 312 to reduce the size of the mounting hole 310, so that the first body 31 tightly embraces the first core shaft 10. When the adjustment arm 323 rotates in the opposite direction of direction A, it can drive the first adjustment block 321 to rotate, so that the first adjustment block 321 and the second adjustment block 322 are separated, thereby releasing the axial clamping force of the adjustment pin 320, causing the first wall portion 311 and the second wall portion 312 to separate from each other, thereby restoring the size of the mounting hole 310, and allowing the first body 31 to release the first core shaft 10.
[0091] The adjustment arm 323 may be formed with a structurally weakened portion 3230, which may be configured as a fracture groove, or the thickness of a portion of the adjustment arm 323 may be reduced to form the structurally weakened portion 3230. Specifically, the adjustment arm 323 needs to have a certain degree of rigidity and stability during normal use, but excessive rigidity may increase the risk of injury to the driver during a collision. The structurally weakened portion 3230 is formed in the adjustment arm 323, and the rigidity and strength at the structurally weakened portion 3230 are reduced. When the vehicle collides and the driver's leg hits the adjustment arm 323, the adjustment arm 323 may be fractured at the structurally weakened portion 3230 when the force applied to the adjustment arm 323 reaches a certain value, thereby avoiding secondary injury to the passenger and thereby helping to improve the safety and reliability of the vehicle. Moreover, when the driver hits the adjustment arm 323, the adjustment arm 323 can drive the first adjustment block 321 to rotate, thereby enabling the first adjustment block 321 to approach the second adjustment block 322, so that the first wall portion 311 and the second wall portion 312 are separated, thereby causing the first core shaft 10 to move relative to the second core shaft 20 along the first direction, thereby achieving a collapse effect.
[0092] According to some embodiments of the present invention, Figure 1-Figure 2 and Figure 5-Figure 7 As shown, the positioning block 33 is assembled in the notch 3101 and the adjustment component 32 is passed through the positioning block 33. The surface of the positioning block 33 facing the first core shaft 10 has a first positioning portion 330. The first core shaft 10 is formed with a second positioning portion 13 that is positioned and matched with the first positioning portion 330. The positioning block 33 is in contact with both the first wall portion 311 and the second wall portion 312.
[0093] Among them, the positioning block 33 is assembled in the notch 3101, and the adjusting pin 320 in the adjusting assembly 32 is passed through the positioning block 33. Along the axial direction of the adjusting pin 320, the two ends of the positioning block 33 are respectively abutted against the first wall portion 311 and the second wall portion 312, so that the first wall portion 311 and the second wall portion 312 can clamp the positioning block 33. The surface of the positioning block 33 facing the first core shaft 10 has a first positioning portion 330, and the first core shaft 10 is formed with a second positioning portion 13 that is positioned and matched with the first positioning portion 330. The first positioning portion 330 cooperates with the second positioning portion 13 to realize the positioning of the first core shaft 10, and can make the first core shaft 10 more stably fixed in the mounting hole 310 between the first wall portion 311 and the second wall portion 312.
[0094] It can be explained that the positioning block 33 can be made of nylon material, which has a certain elasticity and can be deformed when subjected to external force, and can quickly return to its original shape after the external force is removed, so that when the first wall portion 311 and the second wall portion 312 are clamped, the positioning block 33 can be quickly deformed so that the first wall portion 311 and the second wall portion 312 can be close to each other, thereby achieving the effect of the first body 31 clamping the first core shaft 10, and can also enhance the clamping effect of the first body 31 on the first core shaft 10, and can also absorb and disperse the stress and impact generated during the clamping process, protecting other components from damage.
[0095] According to some embodiments of the present invention, the first positioning portion 330 is one of the positioning hole and the positioning column, and the second positioning portion 13 is the other of the positioning hole and the positioning column. This application takes the first positioning portion 330 as the positioning column and the second positioning portion 13 as the positioning hole as an example for explanation. The shape of the positioning column is adapted to the shape of the positioning hole so that the positioning column can be smoothly inserted into the positioning hole to realize the positioning of the positioning block 33 and the first core shaft 10, which can improve the positioning accuracy between the positioning block 33 and the first core shaft 10 and reduce assembly errors, thereby improving the stability and reliability of the steering device 100.
[0096] According to some embodiments of the present invention, Figure 5-Figure 6 As shown, the positioning block 33 may include: a positioning block body 51 and an assembly portion 52, the assembly portion 52 and the positioning block body 51 are fixedly connected and are located on the side of the positioning block body 51 away from the mounting hole 310, the positioning block body 51 is in contact with the first body 31, and the surface of the positioning block body 51 facing the first core shaft 10 has a first positioning portion 330, and the adjustment component 32 is passed through the assembly portion 52.
[0097] Among them, the positioning block 33 may include: a positioning block main body 51 and an assembly part 52, and the assembly part 52 and the positioning block main body 51 are fixedly connected. For example, the assembly part 52 and the positioning block main body 51 can be fixedly connected by bonding, or the assembly part 52 and the positioning block main body 51 are integrally formed, but the utility model is not limited to this. The assembly part 52 and the positioning block main body 51 can also be fixedly connected by other means, as long as the assembly part 52 and the positioning block main body 51 are fixedly connected. The assembly portion 52 is located on the side of the positioning block body 51 away from the mounting hole 310, the positioning block body 51 abuts against the first body 31, and the two ends of the positioning block body 51 respectively abut against the first wall portion 311 and the second wall portion 312 abutting against the first body 31, so that the first wall portion 311 and the second wall portion 312 can clamp the positioning block 33, and the surface of the positioning block body 51 facing the first core shaft 10 has a first positioning portion 330, and the first core shaft 10 is formed with a second positioning portion 13 that is positioned and matched with the first positioning portion 330. The first positioning portion 330 cooperates with the second positioning portion 13 to realize the positioning of the first core shaft 10, and can make the first core shaft 10 more stably fixed in the mounting hole 310 between the first wall portion 311 and the second wall portion 312.
[0098] The second direction is Figure 2 In the Y direction, the adjustment component 32 is passed through the assembly part 52, and the assembly part 52 is formed with a hole. The adjustment component 32 is passed through the hole of the assembly part 52, and can press the positioning block 33 against the surface of the positioning block 33 facing the first core shaft 10 along the second direction, so that the surface of the positioning block 33 facing the first core shaft 10 is in contact with the first core shaft 10, so that the surface of the positioning block 33 facing the first core shaft 10 can firmly hold the upper column tube 12, so as to provide more holding force and support force for the steering device 100.
[0099] According to some embodiments of the present invention, Figure 2As shown, the surface of the positioning block 33 facing the first core shaft 10 abuts against the first core shaft 10. The upper column tube 12 of the first core shaft 10 is cylindrical. The surface of the positioning block 33 facing the first core shaft 10 can be constructed as a curved surface, and the shape of the surface of the positioning block 33 facing the first core shaft 10 is adapted to the shape of the upper column tube 12 of the first core shaft 10, so that the surface of the positioning block 33 facing the first core shaft 10 abuts against the upper column tube 12 of the first core shaft 10, so that the surface of the positioning block 33 facing the first core shaft 10 can hold the upper column tube 12 tightly, and can provide a certain holding force for the steering device 100. When subjected to external force, due to the close contact between the curved surface and the upper column tube 12, the force can be more evenly distributed across the entire contact surface, which helps to reduce stress concentration, thereby improving the bearing capacity of the overall structure and ensuring the consistency of the breaking force. When the first spindle 10 is unlocked, the positioning block 33 and the first spindle 10 are subjected to external force, and the positioning column breaks when the force reaches the force limit, thereby moving the first spindle 10 toward the second spindle 20, reducing damage to the driver.
[0100] Furthermore, the central axis of the adjusting pin 320 and the central axis of the hole through which the positioning block 33 is formed are not in the same horizontal plane. Figure 2 In the Y direction, the central axis of the adjusting pin 320 is located below the central axis of the hole through which the positioning block 33 is penetrated. When the adjusting pin 320 is penetrated into the positioning block 33, the positioning block 33 can be pressed toward the first core shaft 10, so that the surface of the positioning block 33 facing the first core shaft 10 is more closely abutted against the first core shaft 10, so that the surface of the positioning block 33 facing the first core shaft 10 can more firmly hold the upper column tube 12, thereby providing more holding force and supporting force for the steering device 100.
[0101] According to some embodiments of the present invention, the fixing mechanism 30 also includes: a second body 34, the second body 34 includes a first clamping wall 341 and a second clamping wall 342, the first clamping wall 341 and the second clamping wall 342 are opposite and spaced apart, the first wall portion 311 and the second wall portion 312 are located between the first clamping wall 341 and the second clamping wall 342, the first clamping wall 341 is suitable for abutting with a corresponding one of the first wall portion 311 and the second wall portion 312, the second clamping wall 342 is suitable for abutting with a corresponding other one of the first wall portion 311 and the second wall portion 312, and the adjusting component 32 is passed through the first clamping wall 341 and the second clamping wall 342, so that the first clamping wall 341 and the second clamping wall 342 drive the first wall portion 311 and the second wall portion 312 to move closer or farther away.
[0102] The second body 34 includes a first clamping wall 341 and a second clamping wall 342. The first clamping wall 341, the second clamping wall 342, and the adjustment assembly 32 together form the clamping device of the above embodiment, which can clamp the first wall portion 311 and the second wall portion 312 to bring the first wall portion 311 and the second wall portion 312 closer together. The first clamping wall 341 and the second clamping wall 342 are opposite and spaced apart, and can provide a stable clamping space for the first wall portion 311 and the second wall portion 312. The first wall portion 311 and the second wall portion 312 are located between the first clamping wall 341 and the second clamping wall 342. The first clamping wall 341 is adapted to abut against one of the first wall portion 311 and the second wall portion 312, and the second clamping wall 342 is adapted to abut against the other of the first wall portion 311 and the second wall portion 312. This application will be described using the example of the first clamping wall 341 abutting against the first wall portion 311 and the second clamping wall 342 abutting against the second wall portion 312. The first clamping wall 341 and the second clamping wall 342 respectively abut against the first wall portion 311 and the second wall portion 312, thereby ensuring the accuracy and stability of clamping. The adjustment pin 320 of the adjustment assembly 32 is provided through the first clamping wall 341 and the second clamping wall 342. The first adjustment block 321 and the second adjustment block 322 in the adjustment assembly 32 rotate relative to each other, so that the first adjustment block 321 and the second adjustment block 322 move closer or farther away, thereby enabling the first clamping wall 341 and the second clamping wall 342 to drive the first wall portion 311 and the second wall portion 312 closer or farther away, thereby enabling the first clamping wall 341 and the second clamping wall 342 to accurately control the relative position of the first wall portion 311 and the second wall portion 312, thereby achieving high-precision positioning and clamping. When the first clamping wall 341 and the second clamping wall 342 drive the first wall portion 311 and the second wall portion 312 closer together, the size of the mounting hole 310 can be reduced, so that the first body 31 is deformed and holds the first core shaft 10, thereby providing sufficient support and holding force for the steering device 100 to ensure that the steering device 100 remains stable and reliable under normal working conditions.
[0103] Therefore, through the coordinated use of the adjustment component 32, the first clamping wall 341, the second clamping wall 342, the first wall portion 311, and the second wall portion 312, the first body 31 can be deformed and hold the first core shaft 10 tightly, thereby providing sufficient support and holding force for the steering device 100 to ensure that the steering device 100 remains stable and reliable under normal working conditions, and the entire steering device 100 can be made more compact, reducing the space occupied by the steering device 100.
[0104] According to some embodiments of the present invention, Figure 1As shown, the second body 34 may further include: a fixed wall 343 , the fixed wall 343 is fixedly connected to both the first clamping wall 341 and the second clamping wall 342 , and the fixed wall 343 is used to be fixedly connected to the vehicle body.
[0105] The fixing wall 343 is fixedly connected to the first clamping wall 341 and the second clamping wall 342. For example, the fixing wall 343 and the first clamping wall 341 and the second clamping wall 342 can be fixedly connected by welding, or the fixing wall 343 and the first clamping wall 341 and the second clamping wall 342 can be integrally formed, but the present invention is not limited thereto. The fixing wall 343 and the first clamping wall 341 and the second clamping wall 342 can also be fixedly connected by other means, as long as the fixing wall 343 is fixedly connected to the first clamping wall 341 and the second clamping wall 342. The fixing wall 343 is used to be fixedly connected to the vehicle body. For example, the fixing wall 343 and the vehicle body can be fixedly connected by bolts, or the fixing wall 343 and the vehicle body can be fixedly connected by welding, but the present invention is not limited thereto. The fixing wall 343 and the vehicle body can also be fixedly connected by other means, as long as the fixing wall 343 is used to be fixedly connected to the vehicle body.
[0106] Furthermore, by being connected to the vehicle body through the fixed wall 343, it can be ensured that the first clamping wall 341 and the second clamping wall 342 are not prone to shaking or falling off when the vehicle is traveling or subjected to external forces, and the fixed wall 343 serves as a bridge connecting the vehicle body and the first clamping wall 341 and the second clamping wall 342, which can increase the rigidity and deformation resistance of the entire structure, and help to improve the overall safety and stability of the vehicle. In addition, it can also ensure that the clamping force of the first clamping wall 341 and the second clamping wall 342 mainly acts on the first body 31 itself and will not be transmitted to the vehicle body, thereby enabling the adjustment force of the steering device 100 and the connection tightening torque of the steering device 100 and the vehicle body to not affect each other.
[0107] According to some embodiments of the present invention, Figure 1 and Figure 3 As shown, the fixing wall 343 may include a plurality of sub-fixing walls 3431 , and the plurality of sub-fixing walls 3431 are arranged along the first direction.
[0108] The fixed wall 343 may include a plurality of sub-fixed walls 3431. For example, the fixed wall 343 may include two, three, four, or other numbers of sub-fixed walls 3431. However, the present invention is not limited thereto. The fixed wall 343 may also include other numbers of sub-fixed walls 3431, as long as the fixed wall 343 includes a plurality of sub-fixed walls 3431. As an example of the present application, the fixed wall 343 may include two sub-fixed walls 3431, both of which have a surface facing the vehicle body. The surfaces of the two sub-fixed walls 3431 facing the vehicle body are located in the same plane, that is, the surfaces of the two sub-fixed walls 3431 facing the vehicle body are coplanar, and the two sub-fixed walls 3431 are arranged along the first direction, such as Figure 3 As shown, the third direction can be Figure 3 In the Z direction, along the third direction, fixing holes 3433 are respectively formed at both ends of each sub-fixing wall 3431, so the two sub-fixing walls 3431 are formed with four fixing holes 3433, and fasteners can be assembled in the fixing holes 3433 to achieve four-point planar fixation between the steering device 100 and the vehicle body, which can further improve the connection stability between the fixing wall 343 and the vehicle body and the force uniformity of the fixing wall 343, and at the same time, can further reduce the interference of the connection tightening torque between the steering device 100 and the vehicle body on the adjustment of the steering device 100, thereby improving the stability and reliability of the vehicle and improving the driving comfort and safety of the entire vehicle.
[0109] According to some embodiments of the present invention, Figure 1 As shown, at least one sub-fixed wall 3431 has a limiting portion 3432. For example, there may be one, two, three, or other number of sub-fixed walls 3431 with limiting portions 3432. However, the present invention is not limited thereto. Another number of sub-fixed walls 3431 may also have limiting portions 3432, as long as at least one sub-fixed wall 3431 has a limiting portion 3432. As an example of the present application, the fixed wall 343 may include two sub-fixed walls 3431, and the two sub-fixed walls 3431 both have a limiting portion 3432. The limiting portion 3432 may be constructed as a strip hole, and the limiting portion 3432 may also be a limiting platform. The present application takes the limiting portion 3432 as a strip hole as an example for explanation. The limiting portion 3432 may be formed in the middle part of the sub-fixed wall 3431, and a limiting structure corresponding to the limiting portion 3432 may be formed on the vehicle body. The limiting structure may be constructed as a flange structure, and at least part of the flange structure is passed through the strip hole and connected to the strip hole by snap-fitting. It can provide support and limitation for the second body 34 without affecting other structural functions, thereby preventing the second body 34 from unnecessary movement or slipping during the process of fixing and assembling with the vehicle body, ensuring the accuracy and smooth progress of the assembly, and enhancing the stability and safety between the steering device 100 and the vehicle body.
[0110] According to some embodiments of the present invention, Figure 1 As shown, the adjustment component 32 is passed through the first wall portion 311 and the second wall portion 312, the first clamping wall 341 is suitable for abutting against the first wall portion 311, and the second clamping wall 342 is suitable for abutting against the second wall portion 312, at least one of the first clamping wall 341 and the first wall portion 311 has a first bar hole 3411 extending along the second direction, and at least one of the second clamping wall 342 and the second wall portion 312 has a second bar hole 3421 extending along the second direction, the first bar hole 3411 and the second bar hole 3421 are opposite to each other, and the adjustment component 32 is passed through the first bar hole 3411 and the second bar hole 3421, and the second direction is perpendicular to the first direction.
[0111] The second direction can be Figure 2 The second direction is perpendicular to the first direction. At least one of the first clamping wall 341 and the first wall portion 311 has a first strip-shaped hole 3411 extending along the second direction. For example, the first clamping wall 341 has a first strip-shaped hole 3411 extending along the second direction, or the first wall portion 311 has a first strip-shaped hole 3411 extending along the second direction, or both the first clamping wall 341 and the first wall portion 311 have a first strip-shaped hole 3411 extending along the second direction. As long as at least one of the first clamping wall 341 and the first wall portion 311 has a first strip-shaped hole 3411 extending along the second direction, it will be sufficient. This application is described by taking the first clamping wall 341 having the first strip-shaped hole 3411 extending along the second direction as an example.
[0112] At least one of the second clamping wall 342 and the second wall portion 312 has a second strip-shaped hole 3421 extending along the second direction. For example, the second clamping wall 342 has a second strip-shaped hole 3421 extending along the second direction, or the second wall portion 312 has a second strip-shaped hole 3421 extending along the second direction, or both the second clamping wall 342 and the second wall portion 312 have a second strip-shaped hole 3421 extending along the second direction. As long as at least one of the second clamping wall 342 and the second wall portion 312 has a second strip-shaped hole 3421 extending along the second direction, it will be sufficient. This application takes the second clamping wall 342 having the second strip-shaped hole 3421 extending along the second direction as an example for description.
[0113] The first strip hole 3411 and the second strip hole 3421 are opposite to each other, and the adjustment pin 320 of the adjustment assembly 32 is inserted into the first strip hole 3411 and the second strip hole 3421, so that the adjustment pin 320 can move along the second direction within the first strip hole 3411 and the second strip hole 3421. Specifically, when the first adjustment block 321 and the second adjustment block 322 of the adjustment assembly 32 are close to each other, the adjustment assembly 32 can be unlocked, so that the first clamping wall 341 and the second clamping wall 342 release the first body 31, and thus the first core shaft 10 can be released, so that the first core shaft 10 can move downward along the second direction, thereby achieving the position adjustment of the steering device 100 in the second direction.
[0114] According to some embodiments of the present invention, Figure 2 As shown, the steering device 100 further includes an elastic member 40 , which extends along the second direction. Two ends of the elastic member 40 are respectively connected to the second body 34 and the first body 31 .
[0115] The elastic member 40 can be constructed as a spring, extending along the second direction, with both ends of the elastic member 40 connected to the second body 34 and the first body 31, respectively. For example, both ends of the elastic member 40 can be provided with a hook structure 41, and both the second body 34 and the first body 31 can be formed with a through hole 42, a suspension shaft 43, and the like. The hook structure 41 can be inserted into the through hole 42, or the hook structure 41 can be sleeved on the wall of the suspension shaft 43. Furthermore, the first body 31 can be formed with a suspension shaft 43, and the second body 34 can be formed with a through hole 42. The hook structure 41 at one end of the elastic member 40 is inserted into the through hole 42, and the hook structure 41 at the other end of the elastic member 40 is sleeved on the suspension shaft 43, so as to achieve the effect of connecting the elastic member 40 with the second body 34 and the first body 31. Alternatively, the two ends of the elastic member 40 may be fixedly connected to the second body 34 and the first body 31 respectively by welding, but the elastic member 40 may also be fixedly connected to the second body 34 and the first body 31 by other means, as long as the two ends of the elastic member 40 are connected to the second body 34 and the first body 31 respectively.
[0116] When the adjustment arm 323 is unlocked, the adjustment pin 320 can move in the first strip hole 3411 and the second strip hole 3421 along the second direction, so that the first body 31 tends to slide relative to the second body 34. The two ends of the elastic member 40 are respectively connected to the second body 34 and the first body 31, which can play a role in shock absorption and buffering, reducing the impact force and vibration generated by the moment the adjustment arm 323 is unlocked, and can reduce the risk of damage to the steering device 100, thereby effectively extending the service life of the steering device 100, and can also prevent the first body 31 from suddenly sliding relative to the second body 34, thereby improving driving comfort and stability.
[0117] According to some embodiments of the present invention, Figure 4 As shown, the steering device 100 further includes: a component mounting bracket 50 , which is fixed to the fixing mechanism 30 .
[0118] The component mounting bracket 50 is fixed to the fixing mechanism 30. For example, the component mounting bracket 50 and the fixing mechanism 30 can be fixedly connected by bolts, or the component mounting bracket 50 and the fixing mechanism 30 can be fixedly connected by welding. However, the present invention is not limited thereto. The component mounting bracket 50 and the fixing mechanism 30 can also be fixedly connected by other means, as long as the component mounting bracket 50 is fixed to the fixing mechanism 30. Specifically, the component mounting bracket 50 can be mounted on the first body 31 of the fixing mechanism 30. The component mounting bracket 50 can be used to install a wiring harness. As an example of the present application, the component mounting bracket 50 can be fixed to the fixing mechanism 30 by bolts, thereby preventing the component mounting bracket 50 from rotating or displacing during assembly of the wiring harness. It can also effectively prevent the component mounting bracket 50 from loosening, rotating or displacing when bearing the weight and vibration of the wiring harness, thereby ensuring the stability and safety of the wiring harness, and ensuring that the wiring harness can be firmly and orderly fixed in the desired position, while avoiding unnecessary movement or damage during assembly, transportation or use, thereby improving the stability and reliability of the steering device 100.
[0119] According to some embodiments of the present invention, Figure 3 As shown, along the first direction, the end of the first wall portion 311 away from the first core shaft 10 is fixedly connected to the end of the first clamping wall 341 away from the first core shaft 10, and the end of the second wall portion 312 away from the first core shaft 10 is fixedly connected to the end of the second clamping wall 342 away from the first core shaft 10, which can prevent the risk of the first body 31 loosening or falling off relative to the second body 34 during long-term use, further enhance the overall structural strength of the steering device 100, so as to improve the stability and reliability of the steering device 100.
[0120] Furthermore, the end of the first wall portion 311 away from the first core shaft 10 is fixedly connected to the end of the first clamping wall 341 away from the first core shaft 10 by riveting, and the end of the second wall portion 312 away from the first core shaft 10 is fixedly connected to the end of the second clamping wall 342 away from the first core shaft 10 by riveting, or the end of the first wall portion 311 away from the first core shaft 10 is fixedly connected to the end of the first clamping wall 341 away from the first core shaft 10 by bolts, and the end of the second wall portion 312 away from the first core shaft 10 is fixedly connected to the end of the second clamping wall 342 away from the first core shaft 10 by bolts, but the present invention Without limitation thereto, the end of the first wall portion 311 away from the first mandrel 10 and the end of the first clamping wall 341 away from the first mandrel 10 may also be fixedly connected by other means, and the end of the second wall portion 312 away from the first mandrel 10 and the end of the second clamping wall 342 away from the first mandrel 10 may also be fixedly connected by other means, as long as the end of the first wall portion 311 away from the first mandrel 10 and the end of the first clamping wall 341 away from the first mandrel 10 are fixedly connected, and the end of the second wall portion 312 away from the first mandrel 10 and the end of the second clamping wall 342 away from the first mandrel 10 are fixedly connected. This application takes the example of the end of the first wall portion 311 away from the first mandrel 10 and the end of the first clamping wall 341 away from the first mandrel 10 being fixedly connected by riveting, and the end of the second wall portion 312 away from the first mandrel 10 and the end of the second clamping wall 342 away from the first mandrel 10 being fixedly connected by riveting as an example. Riveted fixing has high connection strength, good material compatibility, and high production efficiency, which helps to maintain structural stability, facilitates the connection between different materials, and can also reduce the production cost of the steering device 100.
[0121] According to some embodiments of the present invention, Figure 1 As shown, the outer wall edges of the fixed wall 343 can be provided with a flange structure, which can effectively improve the bearing capacity of the fixed wall 343, so that the fixed wall 343 is not easily deformed or damaged when subjected to external force, thereby improving the connection firmness and reliability between the steering device 100 and the vehicle body, thereby improving the safety and reliability of the entire vehicle.
[0122] Vehicles according to embodiments of the present invention, including the steering device 100 of the above-described embodiments, can meet the required holding force and peak force requirements of the steering device 100 without requiring a crushing structure or a pull-off block structure, thereby reducing the production cost of the steering device 100 and, consequently, the vehicle cost. Furthermore, by providing a stopper 3432 on the fixing wall 343, the risk of the steering device 100 slipping during assembly with the vehicle body can be prevented, thereby reducing the risk of damage to the steering device 100.
