Abstract
Description
Technical Field
[0001] This application relates to the field of automotive technology, and in particular to an automotive steering device and an automobile. Background Technology
[0002] With the development of the automotive industry, adjustable car steering systems have emerged, allowing for adjustments in length or angle to meet different driving needs. When the car is being driven normally, the steering system needs to be locked; therefore, it is equipped with a locking mechanism.
[0003] In related technologies, the locking mechanism of an automotive steering system controls the clamping force through the deformation of a bracket. This bracket needs to also secure the steering system, thus requiring sufficient thickness. However, a thicker metal bracket can affect the precision of clamping force control, making it difficult to balance adjustment forces in both length and angle directions, potentially leading to unreliable locking. Furthermore, bracket deformation during steering system adjustments weakens its securing function, and a certain degree of metal deformation can affect the overall rigidity and strength of the steering system, potentially causing abnormal noises during vehicle operation and steering system adjustments. Summary of the Invention
[0004] Therefore, it is necessary to provide an automotive steering device and an automotive vehicle to address the aforementioned technical problems, thereby improving the overall rigidity, strength, and locking reliability of the automotive steering device.
[0005] This application provides an automotive steering device, comprising: a fixing member fixedly connected to the vehicle body; a movable shaft movably connected to the fixing member; a support member connected to the movable shaft and capable of moving synchronously with the movable shaft; a steering member, one end of which is connected to a steering wheel and the other end of which is rotatably connected to the support member; a connecting assembly sleeved on the movable shaft and movably connected to the movable shaft, with one end of the connecting assembly fixedly connected to the steering member; and a pressure applying member slidably connected to the movable shaft, the pressure applying member being disposed between the connecting assembly and the support member, the pressure applying member being capable of simultaneously applying pressure to the connecting assembly and the support member, thereby fixing the relative positions between the support member and the fixing member and between the connecting assembly and the movable shaft.
[0006] The pressure component presses against the connecting assembly, fixing the connecting assembly to the moving shaft, and also presses against the support component, causing the support component to press against the fixing component. This fixes the relative positions of the support component and the fixing component, thereby fixing the relative positions of the moving shaft and the fixing component. This achieves the relative fixation of the positions of the steering component and the support component, and locks the length and angle of the car steering device.
[0007] Locking the car steering system by applying pressure with pressure components is simpler than locking it by deforming the bracket. This method allows for both angle and length adjustments of the steering system, is less prone to deformation, and improves the strength, rigidity, and locking reliability of the steering system, thus avoiding abnormal noises during car operation and steering system adjustments.
[0008] In one embodiment, the fixing member is provided with an assembly groove, and the movable shaft can be installed in the assembly groove and can move in the assembly groove.

[0010] In one embodiment, the vehicle steering device further includes a first sliding member and a second sliding member, both of which are sleeved on the moving shaft and can slide on the moving shaft. The first sliding member and the second sliding member are respectively disposed on both sides of the pressure member. The pressure member can apply pressure to the support member by means of the first sliding member, and the pressure member can apply pressure to the connecting component by means of the second sliding member.
[0011] In one embodiment, the vehicle steering system further includes a first adjusting member connected to the pressure applying member, the first adjusting member being capable of driving the pressure applying member to apply pressure to the connecting assembly and the support member.
[0012] In one embodiment, the connecting assembly includes at least one first connector and at least one second connector. The first connector is connected to the steering member, and both the first and second connectors are movably connected to the moving shaft. The first connector is capable of moving relative to the moving shaft as the steering member rotates. The second connector has a locked state in which its relative position to the moving shaft is fixed. In the locked state, the second connector can prevent the first connector from moving relative to the moving shaft, thereby fixing the angle between the steering member and the support member.
[0013] In one embodiment, one of the first connector and the second connector is provided with a groove, and the other is provided with a protrusion, the protrusion being able to engage in the groove.
[0014] In one embodiment, a plurality of grooves are configured, and the plurality of grooves are spaced apart along a first direction.
[0015] In one embodiment, the vehicle steering device further includes a second adjusting member disposed on a fixed member, the second adjusting member being connected to a second connecting member, and the second adjusting member being capable of driving the second connecting member to engage or disengage from the first connecting member.

[0031] See Figures 1 to 3 , Figures 1 to 3A schematic diagram of an automotive steering device according to one embodiment of this application is shown. The automotive steering device 10 is used for the connection between the steering wheel and the steering gear, and transmits torque to the steering gear to drive the steering gear to achieve steering. In some embodiments, the automotive steering device 10 includes a fixing member 11, a steering member 12, a support member 13, a moving shaft 14, a connecting assembly 15, and a pressure applying member 16. By applying pressure to the connecting assembly 15 and the support member 13 disposed on the moving shaft 14 by the pressure applying member 16, the relative positions of the steering member 12 and the support member 13 are fixed, thereby locking the automotive steering device 10.
[0032] The fastener 11 is fixedly connected to the vehicle body and is used to secure the vehicle steering device 10. The fastener 11 provides an installation position for the vehicle steering device 10. By fixing it to the vehicle body via the fastener 11, the vehicle steering device 10 is connected to the vehicle body and thus applied to the vehicle's steering system. Furthermore, the fastener 11 is provided with a receiving groove 111, in which the support member 13 is installed. The receiving groove 111 reduces the space occupied by the vehicle steering device 10.
[0033] One end of the steering component 12 is connected to the steering wheel, and the other end is connected to the steering gear, thereby transmitting the torque applied to the steering wheel to the steering gear. One end of the steering component 12 is rotatably connected to the support component 13. By rotating relative to the support component 13, the included angle between the steering component 12 and the support component 13 is changed, thereby changing the overall angle of the vehicle steering device 10. By setting the steering component 12 and the support component 13, the angle of the vehicle steering device 10 can be adjusted to meet different driving needs.
[0034] The movable shaft 14 is movably connected to the fixed member 11, and the support member 13 is connected to the movable shaft 14 and can move synchronously with the movable shaft 14. By moving the movable shaft 14 relative to the fixed member 11, the support member 13 can move relative to the fixed member 11, thereby changing the sum of the lengths of the steering member 12 and the support member 13, and adjusting the overall length of the vehicle steering device 10. Further, the movable shaft 14 can be a sliding shaft, with a sliding connection between the movable shaft 14 and the fixed member 11. In other embodiments, the movable shaft 14 can also be a rolling shaft, with a rolling connection between the movable shaft 14 and the fixed member 11.
[0035] The connecting assembly 15 is used to lock the vehicle steering system 10. The connecting assembly 15 is sleeved on the moving shaft 14 and movably connected to the moving shaft 14, allowing it to move with the moving shaft 14. Typically, the vehicle steering system 10 has a locked state and an unlocked state. One end of the connecting assembly 15 is fixedly connected to the steering member 12. In the locked state, the angle between the steering member 12 and the support member 13 remains unchanged, i.e., the positions of the steering member 12 and the support member 13 are fixed. In the unlocked state, the angle and length of the steering member 12 and the support member 13 can be changed, thereby altering the position of the steering wheel to meet the needs of different drivers and improve driving comfort.
[0036] The pressure-applying component 16 is slidably connected to the moving shaft 14 and disposed between the connecting assembly 15 and the support component 13. The pressure-applying component 16 can apply pressure to the connecting assembly 15 and the support component 13. On the one hand, the pressure-applying component 16 presses against the connecting assembly 15, fixing the connecting assembly 15 to the moving shaft 14. On the other hand, it presses against the support component 13, causing the support component 13 to press against the fixing component 11. This fixes the relative positions of the support component 13 and the fixing component 11, thereby fixing the relative positions of the moving shaft 14 and the fixing component 11. This achieves the relative fixation of the relative positions of the steering component 12 and the support component 13, and locks the length and angle of the vehicle steering device 10.
[0037] The vehicle steering device 10 is locked by applying pressure through the pressure-applying component 16. Compared with the method of deforming the bracket, this method is simple to set up, takes into account the angle and length adjustment of the vehicle steering device 10, and is less prone to deformation. It improves the strength, rigidity and locking reliability of the vehicle steering device 10, and avoids problems such as abnormal noise during vehicle operation and adjustment of the vehicle steering device 10.
[0038] In some embodiments, see Figure 3 The fixing member 11 is provided with an assembly groove 112, and the movable shaft 14 passes through the assembly groove 112 and can move within the assembly groove 112. The movable shaft 14 moves within the assembly groove 112, thereby causing the support member 13 to move with the movable shaft 14, realizing the length adjustment of the vehicle steering device 10. Specifically, the assembly groove 112 is provided on the side wall of the receiving groove 111, and the support member 13 is provided with a through hole for connecting to the movable shaft 14. Both ends of the movable shaft 14 pass through the through holes on both sides of the support member 13 and are installed in the assembly grooves 112 on the two side walls of the receiving groove 111. Both ends of the movable shaft 14 are installed in the assembly grooves 112, ensuring that the movable shaft 14 remains stable during movement and facilitating the length adjustment of the vehicle steering device 10. The shape and size of both ends of the movable shaft 14 match the shape and size of the assembly groove 112.
[0039] Furthermore, the assembly groove 112 extends along a straight line. The straight assembly groove 112 is easy to install on the fixing member 11, has low processing difficulty, and is easy to move in a straight line, so that the length adjustment of the car steering device 10 is smooth and the adjustment distance is controllable.
[0040] The lengths of both the steering component 12 and the support component 13 can be controlled between 120mm and 200mm. The specific lengths of the steering component 12 and the support component 13 can be balanced and adjusted according to the vehicle layout. When the length of the support component 13 is smaller, the linear motion space of the vehicle steering device 10 will increase, and the vehicle steering device 10 can achieve a larger length adjustment. Optionally, the length adjustment range of the vehicle steering device 10 is 60mm-85mm.
[0041] In some embodiments, the steering component 12 is provided with a rotating shaft 121, and the steering component 12 is rotatably connected to the support component 13 via the rotating shaft 121. The steering component 12 and the support component 13 are connected via the rotating shaft 121. By rotating relative to the support component 13, the angle between the steering component 12 and the support component 13 changes, thereby realizing the angle adjustment of the vehicle steering device 10. The rotating shaft 121 can also serve as the rotation axis during angle adjustment.
[0042] Within the same arrangement space, by setting up the steering component 12 and the support component 13, the shorter steering component 12 can increase the angle adjustment range between the steering component 12 and the support component 13, thereby increasing the angle movement space. This results in a reduction in the overall space occupied by the steering component 12 when adjusting the same angle. Optionally, the angle adjustment range of the automotive steering device 10 is 40°-60°.
[0043] In some embodiments, see Figure 4 The vehicle steering device 10 also includes a first sliding member 141 and a second sliding member 142, both of which are sleeved on the moving shaft 14 and can slide on the moving shaft 14. The first sliding member 141 and the second sliding member 142 are respectively disposed on both sides of the pressure applying member 16. The pressure applying member 16 can apply pressure to the support member 13 via the first sliding member 141, and can apply pressure to the connecting assembly 15 via the second sliding member 142. By applying a pressing load, the length and angle adjustment of the vehicle steering device 10 are locked. When the pressure applying member 16 stops applying pressure, the steering member 12 can rotate relative to the support member 13, and the support member 13 can move relative to the fixed member 11, thereby realizing the adjustment of the length and angle of the vehicle steering device 10. Specifically, the first sliding member 141 is disposed between the support member 13 and the pressure applying member 16, and the second sliding member 142 is disposed between the pressure applying member 16 and the connecting assembly 15.
[0044] Furthermore, the pressure-applying component 16 is a shift fork, and the locking of the vehicle steering device 10 is achieved by applying pressure to the shift fork. The pressure-applying component 16 can also be sleeved on the moving shaft 14. In this application, the end of the pressure-applying component 16 is bent. Correspondingly, the upper part of the first sliding member 141 is provided with a protrusion 1521, and the lower part of the second sliding member 142 is provided with a protrusion 1521, so as to form a space between the first sliding member 141 and the second sliding member 142 for the end of the pressure-applying component 16 to be placed. The bent configuration allows the pressure-applying component 16 to simultaneously apply pressure to the first sliding member 141 and the second sliding member 142, thereby locking the vehicle steering device 10 and improving the locking reliability.
[0045] In some embodiments, the vehicle steering device 10 further includes a resilient telescopic member 143, which is sleeved on the movable shaft 14 and disposed between the second sliding member 142 and the end of the movable shaft 14. A support member 13 is sleeved on the telescopic member 143. When pressure is applied, the telescopic member 143 is compressed and contracts, pressing against the side wall of the fixing member 11, thereby fixing the support member 13 and the fixing member 11 relatively, avoiding damage to the support member 13, and improving the relative locking force between the support member 13 and the fixing member 11. When pressure is released, the telescopic member 143 returns to its original shape, allowing the support member 13 to move along the mounting groove 112 of the fixing member 11 to adjust the length of the vehicle steering device 10.
[0046] In some embodiments, see Figure 1 The vehicle steering system 10 also includes a first adjusting member 17 disposed on the support member 13. The first adjusting member 17 can drive the applying member 16 to apply pressure to the support member 13 and the connecting assembly 15. The first adjusting member 17 makes the force applied by the applying member 16 to the support member 13 and the connecting assembly 15 controllable, and the reliability of locking is improved by adjusting the locking force. In other embodiments, the first adjusting member may also be disposed on the fixing member 11.
[0047] Specifically, one end of the pressure-applying member 16 is sleeved on the moving shaft 14 and positioned between the first sliding member 141 and the second sliding member 142, while the other end is connected to the first adjusting member 17. The first adjusting member 17 applies pressure to one end of the pressure-applying member 16, causing the other end of the pressure-applying member 16 to press against the first sliding member 141 and the second sliding member 142, thereby locking the length and angle adjustment of the vehicle steering device 10. As long as the first adjusting member 17 can apply pressure to the pressure-applying member 16, the first adjusting member 17 can be pneumatically driven, electrode-driven, or manually driven.
[0048] In some embodiments, see Figure 5The connecting assembly 15 includes at least one first connecting member 151 and at least one second connecting member 152, with one end of the first connecting member 151 connected to the steering member 12. Both the first connecting member 151 and the second connecting member 152 are sleeved on the moving shaft 14 and are movably connected to the moving shaft 14. The first connecting member 151 and the second connecting member 152 can move along the second direction S2 on the moving shaft 14. Optionally, both the first connecting member 151 and the second connecting member 152 are made of thin spring sheets. Thin spring sheets have good strength and toughness, and the arrangement of multiple thin spring sheets ensures the strength of the vehicle steering device 10 in the locked state.
[0049] The first connecting member 151 can move relative to the moving shaft 14 as the steering member 12 rotates. The second connecting member 152 has a locked state with its relative position fixed to the moving shaft 14. In the locked state, the second connecting member 152 can prevent the first connecting member 151 from moving relative to the moving shaft 14, thus fixing the angle between the steering member 12 and the support member 13. The locking between the first connecting member 151 and the second connecting member 152, based on the locking of the vehicle steering device 10 by the pressure member 16, further locks the vehicle steering device 10, effectively improving the reliability of the locking of the connecting assembly 15. When the first connecting member 151 is locked to the second connecting member 152, the steering member 12 cannot rotate with the support member 13, and thus the angle of the vehicle steering device 10 no longer changes. The arrangement of multiple first connecting members 151 and second connecting members 152 can avoid the reduction of the overall rigidity and strength of the vehicle steering device 10 due to the deformation of some connecting assemblies 15, and the impact on the locking reliability.
[0050] For specific implementation examples, see [link to example]. Figures 6 to 8 The first connector 151 has a groove 1511, and the second connector 152 has a protrusion 1521, which can engage with the groove 1511. The groove 1511 and the protrusion 1521 achieve engagement between the first connector 151 and the second connector 152. The design of the protrusion 1521 and the groove 1511 is simple and reliable, improving the locking reliability of the connecting assembly 15. Specifically, the groove 1511 extends through in the second direction S2 to achieve engagement between the first connector 151 and the second connector 152 in the first direction S1. In other feasible embodiments, the first connector 151 has a protrusion, and the second connector 152 has a groove, with the protrusion engaging with the groove.
[0051] Furthermore, the shapes of the protrusion 1521 and the groove 1511 are matched, thereby achieving a form-locking engagement between the first connector 151 and the second connector 152. This form-locking engagement method is simple to assemble, highly reliable, and suitable for mass production, improving the application prospects of the automotive steering system 10. Moreover, this engagement method has good disassembly capability, facilitating maintenance and inspection on the one hand, and making it easy to lock or disengage between the first connector 151 and the second connector 152 on the other, thus improving the user comfort of the automotive steering system 10.
[0052] In feasible embodiments, see Figure 7 The first connector 151 has multiple grooves 1511 along the first direction S1, and these grooves 1511 are spaced apart along the first direction S1. The first direction S1 intersects with the second direction S2. The multiple grooves 1511 make full use of the space on the first connector 151, facilitating its full utilization. The multiple grooves 1511 along the first direction S1 allow the first connector 151 and the second connector 152 to lock at different positions, resulting in different locking angles between the steering member 12 and the support member 13, thus improving the versatility of the connecting assembly 15.
[0053] Multiple first connectors 151 are arranged along the second direction S2, thereby forming multiple rows of grooves 1511 in the first direction S1. Each row of grooves 1511 can achieve the engagement of the first connectors 151 and the second connectors 152, improving the reliability of the locking of the connecting assembly 15. Optionally, the number of grooves 1511 can be 2 to 10, and the size of the grooves 1511 in the first direction S1 can be 1mm-8mm.
[0054] In some embodiments, the second connector 152 includes a body 1522 and an engaging portion 1523. The engaging portion 1523 is disposed on one side of the body 1522, and a protrusion 1521 is disposed on the engaging portion 1523. Specifically, the position of the engaging portion 1523 corresponds to the position of the first connector 151, thereby enabling the protrusion 1521 to engage with the groove 1511 of the first connector 151. The engaging portion 1523 and the body 1522 of the second connector 152 can be disposed separately, and then multiple second connectors 152 can be connected by fasteners. This arrangement facilitates adjustment of the angle and position of the protrusion 1521 on the engaging portion 1523, improving the locking accuracy of the first connector 151 and the second connector 152. Simultaneously, this arrangement is simple, facilitating mass production and subsequent maintenance and replacement. In other embodiments, the body 1522 and the engaging portion 1523 are integrally disposed.
[0055] Furthermore, the second connector 152 is designed with a certain amount of deformation in the second direction S2, the deviation being 1mm-3mm. The first connector 151 has a groove 1511. When the second connector 152 moves, the protrusion 1521 on the second connector 152 with the certain amount of deformation cooperates with the groove 1511 of the first connector 151 to lock and release. The deviation provides space for the connecting assembly 15 during assembly, ensuring the relatively accurate positions of the first connector 151 and the second connector 152.
[0056] In some embodiments, the connecting assembly 15 further includes two coupling members 153. A first coupling member 151 and a second coupling member 152 are overlapped between the two coupling members 153. Multiple first coupling members 151 are fastened to the coupling members 153 by fasteners to form a first locking unit, and multiple second coupling members 152 are fastened together to form a second locking unit. This arrangement ensures that each first coupling member 151 and each second coupling member 152 remains in the same position, guaranteeing the accuracy of the engagement between the first coupling members 151 and the second coupling members 152.
[0057] Furthermore, the second connecting member 152 is provided with a mounting hole 1524, and the movable shaft 14 is also provided with a mating member 144. The mating members 144 are spaced apart along the second direction S2, and the shape and size of the mating members 144 match the shape and size of the mounting hole 1524. The second connecting member 152 is sleeved on the movable shaft 14 through the mating member 144, so that the second connecting member 152 can rotate relative to the movable shaft 14, but cannot move relative to the movable shaft 14. The first connecting member 151 is provided with a mounting groove 1512, and the size of the mounting groove 1512 matches the outer diameter of the movable shaft 14. The extending direction of the mounting groove 1512 is consistent with the moving direction of the movable shaft 14. The first connecting member 151 can move through the mounting groove 1512. When the steering member 12 rotates, the first connecting member 151 moves relative to the movable shaft 14 through the mounting groove 1512 to realize the rotation of the steering member 12 relative to the support member 13, thereby ensuring the applicability of the connecting assembly 15.
[0058] In some embodiments, the vehicle steering device 10 further includes a second adjusting member 18 disposed on the fixing member 11. The second adjusting member 18 is connected to the second connecting member 152 and can drive the second connecting member 152 to engage or disengage from the first connecting member 151. The second adjusting member 18 is disposed below the second connecting member 152 and can drive the second connecting member 152 to move. When the second connecting member 152 moves, the protrusion 1521 on the second connecting member 152 with a certain amount of deformation cooperates with the groove 1511 of the first connecting member 151 to engage and disengage, thereby realizing the locking and unlocking of the angle adjustment of the vehicle steering device 10. This achieves a second locking and unlocking of the angle adjustment of the vehicle steering device 10, greatly improving the locking reliability. As long as the second adjusting member 18 can enable the second connecting member 152 to move, the second connecting member 152 can be pneumatically driven, electrode driven, or manually driven.
[0059] When locked, the second connecting member 152 is first engaged with the first connecting member 151 via the second adjusting member 18, and then the first adjusting member 17 applies pressure to the pressure applying member 16, causing the pressure applying member 16 to press against the support member 13 and the connecting assembly 15, thereby locking the angle and length adjustment of the vehicle steering device 10. During adjustment, the pressure applying member 16 is first released via the first adjusting member 17, and then the second adjusting member 18 disengages the second connecting member 152 from the first connecting member 151. By moving the steering wheel, the vehicle steering device 10 is stretched or retracted to achieve length adjustment. By moving the steering wheel, the angle between the steering member 12 and the support member 13 changes to achieve angle adjustment of the vehicle steering device 10.
[0060] The automotive steering device 10 of this application occupies a small space yet achieves a large range of length and angle adjustment, improving the adaptability of the automotive steering device 10. At the same time, through the setting of the pressure member 16 and the connecting assembly 15, the automotive steering device 10 achieves dual locking, improving the overall rigidity and strength of the automotive steering device 10 and avoiding problems such as abnormal noise and unreliable locking.
[0061] As part of the same concept, this application also provides a car, which includes a car steering device 10, the car steering device 10 being the car steering device 10 as described in the above embodiments.
[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
