[0002] In related technology, when a vehicle's tire is impacted by a lateral force during off-roading or driving, the impact force is directly transmitted to the steering rod, exerting a significant impact force on it, which can lead to problems such as the steering rod breaking and vehicle loss of control. To prevent the steering gear from breaking or getting stuck, a relief groove is usually designed in the steering rod. When the wheel is subjected to a large lateral impact, the steering rod breaks in the relief groove to absorb the impact force and prevent the steering gear from breaking or getting stuck. However, the driver cannot predict when the rod will break and cannot stop the vehicle in time, resulting in vehicle loss of control. Utility Model Content

[0027] The following describes in detail embodiments of the present application. 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 only used to explain the present application and are not to be construed as limiting the present application.

[0028] Reference below Figure 1-Figure 3 A steering gear assembly 100 for a vehicle according to an embodiment of the present application is described. The steering gear assembly 100 includes a steering rod 1 and a connecting assembly 2. A weakened groove 11 extending circumferentially and recessed toward the interior of the steering rod 1 is formed on the outer wall of the steering rod 1. The steering rod 1 is also provided with first mounting portions 12 located axially on either side of the weakened groove 11. The connecting assembly 2 is sleeved around the outer circumference of the steering rod 1 and engages with the first mounting portions 12, covering the weakened groove 11. The connecting assembly 2 is adapted to link the steering rods 1 on either side of the weakened groove 11 after the weakened groove 11 breaks.

[0029] Currently, when a vehicle's tire is impacted by a side impact during off-roading or driving, the force is directly transmitted to the steering rod, exerting a significant impact on it. This can lead to the rod breaking and the vehicle losing control. To prevent the steering gear from breaking or getting stuck, a relief groove is typically designed into the steering rod. When a wheel is subjected to a significant side impact, the steering rod breaks in the relief groove to absorb the impact and prevent the steering gear from breaking or getting stuck. However, the driver cannot predict when the rod will break and cannot stop the vehicle in time, resulting in loss of control.

[0030] like Figure 1 and Figure 2 As shown, specifically, the steering gear assembly 100 may include a steering rod 1 and a connecting assembly 2. The steering rod 1 can be connected to the steering gear body and the wheel respectively, and the steering rod 1 can move axially to achieve vehicle steering. The outer wall of the steering rod 1 can be formed with a weakening groove 11. The weakening groove 11 can extend along the circumference of the steering rod 1 and can be recessed toward the interior of the steering rod 1. It is understood that the cross-sectional area of ​​a portion of the steering rod 1 perpendicular to the axial direction is smaller than the cross-sectional area of ​​another portion of the steering rod 1 perpendicular to the axial direction to form the weakening groove 11. Due to the provision of the weakening groove 11, when the steering rod 1 is subjected to a large impact force, the weakening groove 11 can absorb the impact force by breaking, thereby preventing the impact force from causing the steering rod 1 to break or preventing the impact force from being transmitted to the steering gear body, causing the steering gear body to be damaged and stuck, thereby affecting the user's control of the vehicle. A first mounting portion 12 may also be provided on the steering rod 1. The first mounting portion 12 may be constructed as two and located on both sides of the weakened groove 11 in the axial direction. In some embodiments, the first mounting portion 12 may be constructed as a protrusion or groove structure.

[0031] like Figure 2 As shown, further, the connecting component 2 can be sleeved on the outer periphery of the steering rod 1, and the connecting component 2 can cooperate with the first mounting portion 12 to achieve fixation between the connecting component 2 and the steering rod 1, and the connecting component 2 can cover the weakened groove 11. It should be noted that an accommodating space is formed inside the connecting component 2, and the weakened groove 11 is located in the space, that is, the connecting component 2 completely covers the weakened groove 11. Since the connecting component 2 cooperates with the first mounting portion 12 on both sides of the weakened groove 11, when the weakened groove 11 is broken, the connecting component 2 can be fixed to the steering rod 1 on both sides of the broken position respectively and achieve linkage with the steering rod 1 on both sides of the broken position. It can be understood that when the steering rod 1 is subjected to a large impact force, the weakened groove 11 is broken, and the connecting component 2 can continue to link the broken steering rod 1, thereby giving the driver a certain reaction time to facilitate the driver to stop the vehicle, thereby effectively solving the problem of vehicle loss of control after the steering rod 1 is broken, and improving driving safety.

[0032] In short, the steering gear assembly 100 of the embodiment of the present application is provided with a steering rod 1 and a connecting component 2 mounted on the steering rod 1. A weakened groove 11 is formed on the steering rod 1, and the connecting component 2 is connected to both sides of the weakened groove 11. When the steering rod 1 is subjected to a large impact force, the weakened groove 11 is unloaded by breaking. At this time, the connecting component 2 can link the steering rods 1 on both sides of the broken position, so that the driver can continue to control the vehicle on the basis of the broken steering rod 1, ensuring that the driver can stop the vehicle in time and ensure the safety of the driver and passengers.

[0033] like Figure 1 As shown, in some embodiments of the present application, the connecting assembly 2 may include a connecting member 21 and a fixing member 22, the connecting member 21 may be sleeved on the outer periphery of the steering rod 1, and the connecting member 21 may cover the weakened groove 11, wherein the connecting member 21 may be bent to a certain extent and will not break or separate, the fixing member 22 may be arranged at both ends of the connecting member 21 in the axial direction, and the fixing member 22 may be connected to the first mounting portion 12, optionally, the fixing member 22 and the first mounting portion 12 may be detachably connected by screws or bolts, or the fixing member 22 and the first mounting portion 12 may be detachably connected by snapping or plugging, the fixing member 22 may serve to fix the connecting member 21 to the outer periphery of the steering rod 1, ensuring that after the weakened groove 11 is broken, the connecting member 21 can realize the linkage of the broken steering rod 1 through the fixing member 22, thereby giving the driver a certain reaction time to facilitate the driver to stop the vehicle.

[0034] like Figure 3 As shown, in some embodiments of the present application, the fixing member 22 may include a fixing portion 221 and a clamping portion 222, and the fixing portion 221 can be connected to the connecting member 21. Optionally, the fixing portion 221 and the connecting member 21 can be constructed as an integrally formed part, and the inner peripheral wall of the fixing portion 221 can be formed with a second mounting portion 2211, and the second mounting portion 2211 can cooperate with the first mounting portion 12. Specifically, the first mounting portion 12 and the second mounting portion 2211 can form a detachable connection by plugging and snapping, and the outer peripheral wall of the fixing portion 221 can form a limiting groove 2212. It should be noted that the inner peripheral wall of the fixing portion 221 is the wall surface of the fixing portion 221 facing the steering rod 1, and the outer peripheral wall of the fixing portion 221 is the wall surface of the fixing portion 221 away from the steering rod 1. The clamping portion 222 can be sleeved on the outer periphery of the fixing portion 221, and the clamping portion 222 can cooperate with the limiting groove 2212, so as to limit the clamping portion 222, and ensure that the clamping portion 222 can effectively fix the fixing portion 221 on the steering rod 1, that is, the first mounting portion 12 and the second mounting portion 2211 can be effectively cooperated. In a specific embodiment, the clamping portion 222 can be constructed as a clamp.

[0035] like Figure 3 As shown, in some embodiments of the present application, the first mounting portion 12 can be constructed as one of the clamping protrusion and the clamping groove, and the second mounting portion 2211 can be constructed as the other of the clamping protrusion and the clamping groove, and the clamping protrusion and the clamping groove can be clamped together to achieve axial limitation between the fixing portion 221 and the steering rod 1. Specifically, the first mounting portion 12 can be constructed as the clamping groove, and the second mounting portion 2211 can be constructed as the clamping protrusion. By clamping the clamping protrusion and the clamping groove together, the clamping protrusion is accommodated in the clamping groove, and the outer surface of the clamping protrusion is stopped against the inner surface of the clamping groove to limit the movement of the clamping protrusion, so that the fixing portion 221 is installed on the steering rod 1.

[0036] like Figure 1 As shown, in some embodiments of the present application, the fixing portion 221 may be formed with a deformable portion 2213 at the end away from the connecting member 21, the deformable portion 2213 may extend in the axial direction, and the clamping portion 222 may be constructed as a hollow annular structure. In order to fix the clamping portion 222 on the limiting groove 2212, the fixing portion 221 needs to reduce the axial size when the clamping portion 222 is assembled. By setting the deformable portion 2213, it is convenient to sleeve the clamping portion 222 on the outer periphery of the fixing portion 221. Specifically, the fixing portion 221 is pressed to shrink during assembly. After the clamping portion 222 is installed, the fixing portion 221 is restored so that the clamping portion 222 is fixed in the limiting groove 2212, thereby realizing the assembly of the limiting portion. In some embodiments, the deformable portion 2213 may be constructed as a notch structure. By pressing the fixing portion 221, the notch can be closed to reduce the size of the fixing portion 221 so as to facilitate the matching of the clamping portion 222 with the limiting groove 2212.

[0037] like Figure 1 As shown, in some embodiments of the present application, the steering rod 1 may include a first rod body 13 and a second rod body 14, the first rod body 13 and the second rod body 14 have the same extension direction, the free end of the first rod body 13 can be linked with the wheel, and the free end of the second rod body 14 can be linked with the steering gear body, and a first mounting portion 12 can be formed on the first rod body 13 and the second rod body 14 respectively, wherein a weakening groove 11 is formed at the connection between the first rod body 13 and the second rod body 14, and a fixing portion 221 is provided at both ends of the connection portion, and the two fixing portions 221 can respectively cooperate with the first mounting portion 12 of the first rod body 13 and the first mounting portion 12 of the second rod body 14, so as to realize that the connecting component 2 links the first rod body 13 and the second rod body 14.

[0038] like Figure 1 and Figure 2As shown, in some embodiments of the present application, the connecting member 21 can be constructed as a corrugated tube structure, and the corrugated tube structure can be composed of a plurality of arc structures. By constructing the connecting member 21 as a corrugated tube structure, the ductility of the connecting member 21 can be enhanced, ensuring that the connecting member 21 can bend under force without breaking, thereby ensuring that the wheels will not be out of control of the steering wheel, making the entire vehicle controllable.

[0039] like Figure 3 As shown, in some embodiments of the present application, the weakening groove 11 can be constructed as an annular groove. By constructing the weakening groove 11 as an annular groove, it can be ensured that when the steering rod 1 is subjected to impact force in any direction, the weakening groove 11 can absorb the impact force by breaking, thereby avoiding the impact force causing the steering rod 1 to break or avoiding the impact force from being transmitted to the steering gear body to cause the steering gear body to be damaged and stuck, thereby affecting the user's control of the vehicle.

[0040] In some embodiments of the present application, the shortest distance between the first mounting portion 12 and the weakened groove 11 is L, satisfying the relationship: 5mm≤L≤20mm. It can be understood that the shortest distance between the first mounting portion 12 and the weakened groove 11 can be any value between 5mm and 20mm. For example, the shortest distance between the first mounting portion 12 and the weakened groove 11 can be but not limited to 5mm, 10mm, 15mm, 20mm, etc. If the shortest distance between the first mounting portion 12 and the weakened groove 11 is too small, the deformation of the connecting component 2 will increase. If the shortest distance between the first mounting portion 12 and the weakened groove 11 is too large, the cost of the connecting component 2 will increase. Therefore, by setting the shortest distance between the first mounting portion 12 and the weakened groove 11 within the above range, it can be ensured that the connecting component 2 can link the steering rod 1 on both sides of the broken position, so that the driver can continue to control the vehicle after the steering rod 1 is broken, ensuring that the driver can stop the vehicle in time and ensure the safety of the driver and passengers.

When the steering rod 1 is subjected to a large impact force, the weakening groove 11 is unloaded by breaking. At this time, the connecting component 2 can link the steering rods 1 on both sides of the broken position, thereby giving the driver a certain reaction time to facilitate the driver to stop the vehicle, thereby effectively solving the problem of vehicle loss of control after the steering rod 1 breaks, and improving the safety of the vehicle.
