Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The following is for reference. Figures 1-20 The steering assembly 100 according to an embodiment of the present invention enables quick assembly and disassembly of the steering wheel frame 1 on the base 2, has low cost, and is applicable to foldable steering wheel structures.

[0023] like Figures 1-4 As shown, the steering assembly 100 according to an embodiment of the present invention includes: a steering wheel frame 1, a base 2, and a connecting structure 3.

[0024] The steering wheel frame 1 and the base 2 can be fixedly connected, so that the steering wheel frame 1 can drive the base 2 to rotate, thereby controlling the vehicle steering.

[0025] The connection structure 3 includes a connecting joint 31 and a pre-tightening component 32. The connecting joint 31 passes through the steering wheel frame 1 and is circumferentially fixedly connected to the steering wheel frame 1. The connecting joint 31 is axially inserted into the base 2 and is circumferentially fixedly connected to the base 2. The pre-tightening component 32 is connected to the connecting joint 31 and is used to elastically pre-tighten the connecting joint 31 toward the base 2. The connecting joint 31 is adapted to overcome the elastic pre-tightening force of the pre-tightening component 32 under the action of external force so as to axially separate from the base 2.

[0026] In other words, the steering wheel frame 1 and the base 2 can be fixedly connected by the connecting structure 3, thereby realizing the transmission cooperation between the steering wheel frame 1 and the base 2. That is, the connecting structure 3 can enable the steering wheel frame 1 to drive the base 2 to rotate, thereby controlling the vehicle steering.

[0027] Specifically, the connecting joint 31 can pass through the steering wheel frame 1, and the steering wheel frame 1 and the connecting joint 31 are fixedly connected in the circumferential direction. That is, the connecting joint 31 and the steering wheel frame 1 can be circumferentially limited and fixed. The connecting joint 31 can be axially inserted into the base 2, and the connecting joint 31 and the base 2 are fixedly connected in the circumferential direction. Thus, the connecting structure 3 enables the steering wheel frame 1 and the base 2 to be relatively fixed in the circumferential direction of the connecting joint 31. In addition, the pre-tightening component 32 can elastically pre-tighten the connecting joint 31 toward the base 2. That is, the pre-tightening component 32 can keep the connecting joint 31 axially inserted with the base 2, thereby ensuring the relative fixation of the steering wheel frame 1 and the base 2 in the circumferential direction of the connecting joint 31. The user can apply external force to the connecting joint 31, such as manually applying an external force to the connecting joint 31 to move it away from the base 2, thereby separating the connecting joint 31 from the base 2, that is, realizing the separation of the steering wheel frame 1 and the base 2.

[0028] Therefore, the steering wheel frame 1 and the base 2 can be connected by the connecting joint 31, that is, the steering wheel frame 1 and the base 2 can be relatively fixed in the circumferential direction along the connecting joint 31. In actual driving, the rotation of the steering wheel frame 1 around the axis of the connecting joint 31 can be reduced, improving driving safety. Moreover, the steering wheel frame 1 can drive the base 2 to rotate through the connecting joint 31, thereby realizing the control of vehicle steering.

[0029] Furthermore, users can flexibly control the connection between the connector 31 and the base 2, thereby enabling quick installation and disassembly of the steering wheel frame 1 and the base 2. The operation is convenient, allowing users to flexibly customize the steering wheel frame 1 according to their own needs. Replacement is convenient and costs can be reduced.

[0030] According to the present invention, the steering assembly 100 can quickly install and disassemble the steering wheel frame 1 and the base 2 through the pre-tightening component 32, which is convenient to operate and allows users to customize the steering wheel frame 1 to meet their own needs. Compared with the traditional structure, the cost is lower and it can be applied to the steering wheel structure that can be flipped and folded.

[0031] In some embodiments, the pretensioning assembly 32 includes a positioning member 321 and an elastic member 322. The positioning member 321 is mounted on the steering wheel frame 1, and the elastic member 322 elastically presses against the positioning member 321 and the connecting joint 31 respectively. The elastic member 322 is used to apply an elastic pretensioning force to the connecting joint 31 toward the base 2. That is, the connecting joint 31 can be pretensioned toward the base 2 by the mutual cooperation of the elastic member 322 and the positioning member 321, thereby realizing the transmission connection between the steering wheel frame 1 and the base 2.

[0032] Specifically, such as Figures 1-4 , Figure 8 and Figure 9 As shown, the positioning member 321 is installed and fixed to the steering wheel frame 1, and the elastic member 322 is disposed between the positioning member 321 and the connecting joint 31. That is, one end of the elastic member 322 presses against the positioning member 321, and the other end presses against the connecting joint 31, so that the elastic member 322 can apply elastic force to the positioning member 321 and the connecting joint 31 respectively. Under the push of the elastic force, the connecting joint 31 is inserted into the base 2 and pre-tightened with the base 2.

[0033] Therefore, through the cooperation of the positioning member 321 and the elastic member 322, the elastic member 322 can apply an elastic force close to the base 2 to the connecting joint 31, thereby realizing the transmission connection between the steering wheel frame 1 and the base 2. The elastic force can also pre-tighten the connecting joint 31 toward the base 2, thereby reducing the risk of the connecting joint 31 detaching from the base 2, reducing the probability of the steering wheel frame 1 separating from the base 2, and improving driving safety.

[0034] In some embodiments, the steering wheel frame 1 is formed with a through-hole 11 for a connecting joint 31, and the positioning member 321 and the elastic member 322 are both installed in the through-hole 11, with the positioning member 321 located at the end of the elastic member 322 away from the base 2, and at least a portion of the connecting joint 31 protruding from the end of the through-hole 11 away from the base 2.

[0035] Specifically, such as Figures 1-4 , Figure 8 and Figure 9 As shown, the through-hole 11 is positioned facing the base 2, the connecting joint 31 passes through the through-hole 11, and the positioning member 321 and the elastic member 322 are disposed in the through-hole 11. The elastic member 322 is disposed between the positioning member 321 and the connecting joint 31, and the positioning member 321 is located at the end of the elastic member 322 away from the base 2, so that the elastic member 322 can apply an elastic force toward the base 2 to the connecting joint 31, and the connecting joint 31 extends out from the end of the through-hole 11 away from the base 2.

[0036] Thus, the elastic element 322 and the positioning element 321 can apply an elastic force to the connecting joint 31 to move it toward the base 2, thereby achieving a fixed connection between the connecting joint 31 and the base 2, so that the steering wheel frame 1 and the base 2 are fixedly connected. The connecting joint 31 extends from the end of the fixing hole 11 away from the base 2, so that the user can apply an elastic force to the connecting joint 31 to move it away from the base 2 through the extended part, so that the connecting joint 31 is separated from the base 2, thereby disconnecting the steering wheel frame 1 from the base 2, and realizing the quick installation and quick disassembly of the steering wheel frame 1 and the base 2.

[0037] In some embodiments, the outer peripheral wall of the connecting joint 31 is provided with a limiting baffle 311 that protrudes radially outward, and a positioning member 321 is distributed axially opposite to the side of the limiting baffle 311 away from the base 2. An elastic member 322 is sleeved on the connecting joint 31 and elastically presses against the positioning member 321 and the limiting baffle 311. That is, the elastic member 322 can apply an elastic force to the connecting joint 31 through the limiting baffle 311, thereby pushing the connecting joint 31 to move.

[0038] Specifically, such as Figure 4 , Figure 8 and Figure 9 As shown, the limiting baffle 311 is radially protruding outward on the outer peripheral wall of the connecting joint 31. The positioning member 321 is distributed opposite to the limiting baffle 311 and is located on the side of the limiting baffle 311 away from the base 2. The elastic member 322 is disposed between the limiting baffle 311 and the positioning member 321, and the two ends of the elastic member 322 abut against the limiting baffle 311 and the positioning member 321 respectively. The elastic member 322 can generate elastic force that acts on the limiting baffle 311 and the positioning member 321 respectively. That is, the elastic member 322 can push the connecting joint 31 through the limiting baffle 311 so that the connecting joint 31 is fixedly connected to the base 2.

[0039] Therefore, by setting the limit stop 311, the elastic element 322 can push the connecting joint 31 toward the base 2 for pre-tightening, thereby realizing the fixed connection between the connecting joint 31 and the base 2. The steering wheel frame 1 can be connected to the base 2 for transmission so that the user can flexibly control the vehicle steering through the steering wheel frame 1.

[0040] The limiting baffle 311 may be provided with a limiting post 3112 extending axially. The elastic element 322 may be constructed as a spring, which can be sleeved on the limiting post 3112 to be fixed with the connecting joint 31, thereby generating an elastic force by pressing against the positioning element 321 and the connecting joint 31. Furthermore, the elastic element 322 may be provided as one, two, or more, and the specific number can be flexibly selected. Multiple elastic elements 322 are distributed circumferentially along the outer peripheral wall of the connecting joint 31.

[0041] And / or, in other embodiments, the positioning member 321 is snapped into the through fixing hole 11, so that the positioning member 321 can be snapped into and fixed to the steering wheel frame 1, so that the positioning member 321 can be flexibly installed and removed relative to the steering wheel frame 1, making the installation flexible and convenient.

[0042] Specifically, a fixing buckle 3212 can be provided on the positioning member 321, and a fixing groove 112 that engages with the fixing buckle 3212 is provided in the through fixing hole 11. The positioning member 321 can be installed and fixed in the through fixing hole 11 by the engagement of the fixing buckle 3212 and the fixing groove 112.

[0043] Specifically, such as Figure 10 and Figure 11 As shown, two fixing buckles 3212 can be provided on the outer peripheral edge of the positioning member 321. The fixing buckles 3212 are radially distributed on the outer peripheral edge of the positioning member 321, and two fixing slots 112 are correspondingly provided in the through fixing hole 11. When the positioning member 321 is installed into the through fixing hole 11, the two fixing buckles 3212 and the two fixing slots 112 can be engaged and fixed one by one, thereby realizing the fixed installation of the positioning member 321 in the through fixing hole 11.

[0044] In some embodiments, the inner peripheral wall of the fixing hole 11 is provided with a transmission mating groove 111 that extends axially and opens radially inward; wherein, the outer peripheral wall of the positioning member 321 is provided with a first transmission protrusion 3211, the first transmission protrusion 3211 extends into the transmission mating groove 111 and engages with the steering wheel frame 1 circumferentially. That is, the transmission mating groove 111 and the first transmission protrusion 3211 can engage circumferentially, thereby enabling the steering wheel frame 1 and the positioning member 321 to achieve circumferentially engaging.

[0045] Specifically, such as Figures 11-13 As shown, the inner peripheral wall of the through-fixing hole 11 may be provided with two axially extending and radially inwardly opening transmission mating grooves 111. The outer peripheral wall of the positioning member 321 is provided with a first transmission protrusion 3211 corresponding to the two transmission mating grooves 111. When the positioning member 321 is installed into the through-fixing hole 11, the first transmission protrusion 3211 can extend into the transmission mating groove 111 and perform circumferential limiting mating with the transmission mating groove 111.

[0046] And / or, in other embodiments, the outer peripheral wall of the limiting baffle 311 is provided with a second transmission protrusion 3111, which extends into the transmission mating groove 111 and engages with the steering wheel frame 1 in a circumferential transmission manner. That is, the second transmission protrusion 3111 of the limiting baffle 311 can engage with the transmission mating groove 111 in a circumferential transmission manner, thereby enabling the steering wheel frame 1 and the connecting joint 31 to achieve a circumferential transmission engagement.

[0047] Specifically, such as Figures 11-13 As shown, the outer peripheral wall of the limiting baffle 311 is provided with a second transmission protrusion 3111 corresponding to the two transmission mating grooves 111. When the connecting joint 31 passes through the through fixing hole 11, the two second transmission protrusions 3111 can respectively extend into the transmission mating grooves 111, thereby realizing the transmission mating between the second transmission protrusions 3111 and the transmission mating grooves 111, so that the connecting joint 31 and the steering wheel frame 1 can perform circumferential limiting mating.

[0048] Therefore, through the circumferential limiting fit between the first transmission protrusion 3211 and the second transmission protrusion 3111 and the transmission mating groove 111, the circumferential limiting fixation of the positioning member 321 and the steering wheel frame 1 and the connecting joint 31 and the steering wheel frame 1 can be realized respectively, that is, the circumferential limiting fixation of the positioning member 321, the steering wheel frame 1 and the connecting joint 31 is realized, which is beneficial to the transmission between the three.

[0049] In some embodiments, the connecting joint 31 includes a plug-in transmission section 312, an intermediate transmission section 313, and an operating part 314 connected sequentially along the axial direction. The plug-in transmission section 312 is adapted to be axially plugged into the base 2 and circumferentially driven. The intermediate transmission section 313 passes through the through-fixing hole 11 and circumferentially drives the steering wheel frame 1. The operating part 314 passes through the positioning member 321 and at least partially extends outside the through-fixing hole 11. That is, the connecting joint 31 can be circumferentially fixed to the base 2 through the plug-in transmission section 312, circumferentially fixed to the steering wheel frame 1 through the intermediate transmission section 313, and the operating part 314 allows the user to quickly install and remove the connecting joint 31.

[0050] Specifically, such as Figures 6-8 As shown, the connecting joint 31 is pre-tightened toward the base 2 under the elastic force of the elastic element 322, so that the insertion transmission section 312 is axially inserted with the base 2 to realize the circumferential transmission cooperation between the connecting joint 31 and the base 2, so that the intermediate transmission section 313 is circumferentially transmitted with the steering wheel frame 1 through the through-fixed hole 11, and the user can drive the connecting joint 31 to move in the direction that separates it from the base 2 through the operating part 314.

[0051] Therefore, by inserting the transmission section 312, the intermediate transmission section 313, and the operating part 314, the circumferential fixed connection between the connecting joint 31 and the base 2 and between the connecting joint 31 and the steering wheel frame 1 can be realized. The steering wheel frame 1 can drive the base 2 to rotate, thereby controlling the vehicle steering. In addition, the user can flexibly control the insertion and separation of the connecting joint 31 and the base 2 through the operating part 314, thereby controlling the installation and removal of the steering wheel frame 1 and the base 2. The operation is quick and convenient.

[0052] In some embodiments, the steering wheel frame 1 includes a connected steering wheel rim 12 and steering wheel spokes 13. The base 2 is provided with a selectively rotatable rotating spindle 21. One end of the rotating spindle 21 has an axially open through-hole 214. A connecting joint 31 is inserted through and connected to the end of the steering wheel spoke 13 away from the steering wheel rim 12 and axially inserted into the through-hole 214 to engage with the rotating spindle 21 in a circumferential transmission manner. That is, by having the connecting joint 31 pass through the steering wheel spokes 13 and the rotating spindle 21, a circumferential fixed connection between the steering wheel frame 1 and the base 2 is achieved.

[0053] Specifically, such as Figures 1-4 and Figures 14-16 As shown, the steering wheel spokes 13 can be connected to the steering wheel rim 12 and the tilting spindle 21 respectively. For example, one end of the steering wheel spokes 13 can be fixedly connected to the steering wheel rim 12, and the other end of the steering wheel spokes 13 can be fixedly connected to the tilting spindle 21, thereby realizing the fixed connection between the steering wheel frame 1 and the base 2. The end of the steering wheel spokes 13 away from the steering wheel rim 12 can be provided with a through-fixing hole 11. The connecting joint 31 can pass through the through-fixing hole 11 to be axially inserted into the through-connecting hole 214 on the tilting spindle 21, thereby realizing the circumferential transmission cooperation between the connecting joint 31 and the tilting spindle 21.

[0054] Thus, the steering wheel spokes 13 can be fixedly connected to the tilting spindle 21 through the connecting joint 31, thereby achieving a fixed connection between the steering wheel frame 1 and the base 2, so that the user can drive the vehicle to rotate through the steering wheel frame 1.

[0055] The main rotating shaft 21 can rotate around the axis, and the steering wheel frame 1 can rotate together with the main rotating shaft 21, thereby realizing the storage and folding of the steering wheel frame 1.

[0056] In some embodiments, the steering wheel spokes 12 are provided with operation buttons, and a first connecting harness 131 electrically connected to the operation buttons is passed through the steering wheel spokes 13. A second connecting harness 211 electrically connected to the vehicle control system is provided inside the tilting spindle 21. The first connecting harness 131 and the second connecting harness 211 are plugged into each other and form an electrical connection. That is, the electrical connection between the steering wheel frame 1 and the base 2 can be achieved through the electrical connection between the first connecting harness 131 and the second connecting harness 211, so that the user can transmit control signals to the vehicle control system through the steering wheel frame 1.

[0057] Specifically, such as Figure 4 and Figures 16-18As shown, a first connecting harness 131 electrically connected to the operation buttons is installed inside the steering wheel spokes 13. That is, the operation buttons can transmit control signals to the outside through the first connecting harness 131. The first connecting harness 131 is electrically connected to the second connecting harness 211, thereby enabling the steering wheel spokes 13 to be electrically connected to the vehicle control system. The user can transmit control signals to the vehicle control system through the operation buttons on the steering wheel rim 12, and then control various functional modules of the vehicle, such as controlling the lights to turn on or off, or controlling the on or off of other functions.

[0058] It should be noted that a wiring harness through hole 315 may be provided on the side wall of the connector 31. The first connecting wiring harness 131 can be inserted into the connector 31 through the wiring harness through hole 315 to make an electrical connection with the second connecting wiring harness 211 in the tilting spindle 21 when the connector 31 is plugged into the tilting spindle 21, thereby realizing the circumferential fixed plugging and electrical connection between the steering wheel spoke 13 and the tilting spindle 21.

[0059] And / or, in some other embodiments, the flipping spindle 21 is provided with a magnetic attracting element 212, which magnetically attracts the connecting joint 31. That is, the connecting joint 31 and the flipping spindle 21 can be attracted by the magnetic attracting element 212.

[0060] Specifically, such as Figures 16-18 As shown, the magnetic attraction component 212 can be sleeved on the outside of the rotating main shaft 21 near the end of the connecting joint 31. The connecting joint 31 is made of a magnetic material. During the installation of the steering wheel frame 1 and the base 2, the connecting joint 31 is brought close to the rotating main shaft 21. At this time, the connecting joint 31 can move towards the rotating main shaft 21 under the attraction of the magnetic attraction component 212, thereby realizing the insertion and fixation of the connecting joint 31 and the rotating main shaft 21.

[0061] Therefore, the first connecting harness 131 and the second connecting harness 211 can achieve electrical connection between the steering wheel frame 1 and the base 2, and the magnetic attracting member 212 can drive the connecting joint 31 to be inserted and fixed with the tilting spindle 21, thereby realizing the installation of the steering wheel frame 1 and the base 2. In addition, the elastic member 322 and the magnetic attracting member 212 can jointly apply a force to the connecting joint 31 to bring it closer to the tilting spindle 21, thereby greatly reducing the risk of the connecting joint 31 loosening and falling off.

[0062] In some embodiments, the first connecting wire harness 131 is provided with a first magnetic connection end 1311, and the second connecting wire harness 211 is provided with a second magnetic connection end 2111. The first magnetic connection end 1311 is adapted to magnetically engage with the second magnetic connection end 2111. That is, the first connecting wire harness 131 and the second connecting wire harness 211 can be automatically electrically connected under the magnetic engagement of the first magnetic connection end 1311 and the second magnetic connection end 2111.

[0063] Specifically, such as Figures 16-18 As shown, the first magnetic connection end 1311 of the first connecting wire harness 131 and the second magnetic connection end 2111 of the second connecting wire harness 211 can be respectively provided with magnetic pole arrays, and the magnetic pole array on the second magnetic connection end 2111 of the second connecting wire harness 211 can be correspondingly provided with the magnetic pole array on the first magnetic connection end 1311 of the first connecting wire harness 131, so that the first magnetic connection end 1311 and the second magnetic connection end 2111 can be electrically connected under the action of magnetic force.

[0064] In this design, the first magnetic connection end 1311 and the second magnetic connection end 2111 have multiple conductive protrusions 1311a on their respective end faces facing each other, and multiple conductive recesses 2111a on the other. The multiple conductive protrusions 1311a extend into the multiple conductive recesses 2111a in a one-to-one conductive engagement. That is, the number of conductive protrusions 1311a and conductive recesses 2111a can be two, three, or more, and the specific number can be flexibly selected.

[0065] Specifically, such as Figure 19 and Figure 20 As shown, a plurality of conductive protrusions 1311a are provided on the end face of the first magnetic connection end 1311, and a plurality of conductive recesses 2111a are provided on the end face of the second magnetic connection end 2111. The plurality of conductive protrusions 1311a and the plurality of conductive recesses 2111a can be plugged into each other, that is, the plurality of conductive protrusions 1311a can extend into the conductive recesses 2111a one by one, thereby realizing the conductive engagement between the conductive protrusions 1311a and the conductive recesses 2111a, that is, realizing the electrical connection between the first connecting wire harness 131 and the second connecting wire harness 211.

[0066] The conductive protrusions 1311a and conductive recesses 2111a can be irregularly arranged on the first magnetic connection end 1311 and the second magnetic connection end 2111, and the magnetic pole arrays are correspondingly arranged. This allows the magnetic pole arrays to adjust the first magnetic connection end 1311 circumferentially when the first magnetic connection end 1311 is connected to the second magnetic connection end 2111, so that the conductive protrusions 1311a can be inserted into the conductive recesses 2111a one by one.

[0067] Thus, through the magnetic attraction of the first magnetic connection end 1311 and the second magnetic connection end 2111, the conductive protrusion 1311a and the conductive recess 2111a can be conductively engaged, thereby realizing the electrical connection between the first connecting wire harness 131 and the second connecting wire harness 211.

[0068] Furthermore, the end of the connecting joint 31 away from the base 2 can extend outward through the through hole 3213 on the positioning member 321, that is, the operating part 314 of the connecting joint 31 passes through the positioning member 321. The shapes of the operating part 314 and the through hole 3213 on the positioning member 321 can match each other, such as being set as a rectangle, thereby further enabling the connecting joint 31 and the positioning member 321 to achieve circumferential limiting and fixing.

[0069] In some embodiments, the connecting joint 31 and the flip spindle 21 can be circumferentially limited and fixed by a spline. That is, the ends of the connecting joint 31 and the flip spindle 21 that are inserted into each other can be respectively set as a spline and a spline mating part. When the connecting joint 31 is inserted into the flip spindle 21, the spline and the spline mating part can be circumferentially limited and fitted, so that the connecting joint 31 and the flip spindle 21 are relatively fixed in the circumferential direction.

[0070] Furthermore, the connecting joint 31 is provided with a positioning key 316, and the rotating spindle 21 is provided with a positioning groove that engages with the positioning key 316. When the connecting joint 31 and the rotating spindle 21 are connected, the positioning key 316 can extend into the positioning groove to achieve circumferential positioning of the connecting joint 31 and the rotating spindle 21, and can further achieve circumferential limiting and fixing of the connecting joint 31 and the rotating spindle 21.

[0071] In some embodiments, the tilting spindle 21 is further provided with a drive link 213, and the tilting spindle 21 is provided with a wire channel to accommodate the second connecting wire harness 211 and connect it to the vehicle control system. The drive link 213 is disposed on the outer peripheral wall of the tilting spindle 21 so that the drive link 213 and the wire channel are not coaxial. When the drive link 213 drives the tilting spindle 21 to rotate, the portion of the second connecting wire harness 211 that extends only from the outside of the tilting spindle 21 to the base 2 can generate a small range of traction displacement, thereby greatly reducing the relative displacement between the first connecting wire harness 131 and the second connecting wire harness 211, and thus greatly reducing the wear of the wire harness.

[0072] Furthermore, when the drive link 213 drives the rotating spindle 21 to rotate in order to realize the folding of the steering wheel frame 1, the connecting structure 3 can avoid other structures, such as the instrument panel, thereby reducing the risk of motion interference of the steering wheel frame 1. When the steering wheel frame 1 is unfolded, the connecting structure 3 can maintain the fixed connection between the steering wheel frame 1 and the base 2.

[0073] Therefore, the steering wheel frame 1 can be folded and stored by driving the linkage 213. During the folding and unfolding of the steering wheel frame 1, the connecting joint 31 can remain connected to the flipping spindle 21, thereby achieving the connection and fixation between the steering wheel frame 1 and the base 2, which helps to improve the user experience.
