Description

Technical Field

[0001] This application relates to the field of automotive parts installation technology, and in particular to a steering wheel mechanism. Background Technology

[0002] The steering wheel is a wheel-shaped object used to control the direction of a car's movement. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft.

[0003] In related technologies, the steering wheel mechanism includes a steering wheel, a steering shaft, and a steering gear. The steering wheel and the steering shaft are coaxially fixedly connected by bolts. The steering shaft is connected to the steering gear. Two tie rods are installed on the steering gear, and the two tie rods are respectively connected to the two front wheels of the car. When the vehicle turns, turning the steering wheel drives the steering shaft to rotate. The rotation of the steering shaft causes the steering gear to act, which causes the two tie rods to pull the two wheels to swing, thus achieving steering.

[0004] Regarding the aforementioned technologies, in sports cars, due to their low body and typically cramped interior space, the driver's seating position tends to be reclined. When getting out of the car, the driver needs to sit up straight and adjust their center of gravity before they can get out stably. The presence of the steering wheel can also affect the driver's ability to get up, making it inconvenient for them to get out of the car. Summary of the Invention

[0005] In order to reduce the impact of the steering wheel on the driver getting out of the vehicle, this application provides a steering wheel mechanism.

[0006] The steering wheel mechanism provided in this application adopts the following technical solution:

[0007] A steering wheel mechanism includes a steering wheel body and a center console; the steering wheel body includes an operating plate and a mounting base, the operating plate is rotatably connected to the mounting base, and a connecting member is rotatably connected to the side of the mounting base away from the operating plate.

[0008] An opening is provided on the outer wall of the center console, a mounting bracket is provided inside the center console, the connector is slidably connected to the inner wall of the mounting bracket, and a drive component is provided inside the center console to drive the connector to move.

[0009] By adopting the above technical solution, when the driver needs to get out of the vehicle, the motor-driven gear mechanism inside the mounting bracket can be activated first, causing the mounting bracket to rotate around the connecting member. Simultaneously, this rotates the control panel to a horizontal position. Then, the drive mechanism is activated, causing the drive shaft to pull the connecting member towards the center console, thereby moving the control panel through the opening into the center console. Once the control panel is inside the center console, the space occupied by the steering wheel is reduced, thus minimizing the impact of the steering wheel on the driver's exit from the vehicle.

[0010] Preferably, the mounting bracket also has a baffle for closing the opening slidably connected inside, and the mounting bracket is provided with a drive motor for moving the baffle.

[0011] By adopting the above technical solution, after the control panel enters the center console, the driver can start the drive motor, causing the drive shaft of the drive motor to push the baffle towards the opening. After the baffle moves to close the opening, the drive motor can stop working. The baffle can cover the opening, reducing the possibility of dust entering the center console through the opening when the driver leaves the vehicle for a long time.

[0012] Preferably, a slide rail is provided on the inner side wall of the mounting bracket, and a mounting frame for mounting the baffle is provided on one side of the baffle. The mounting frame is slidably connected to the slide rail and is connected to the drive shaft of the drive unit. A slide rail is also provided on the inner side wall of the mounting bracket, and a sliding frame is connected to one side of the connector. The sliding frame is slidably connected to the slide rail and is connected to the drive shaft of the drive unit.

[0013] Normally, when connectors and baffles are directly slidably connected to the mounting frame, the width of the connectors and baffles needs to be the same as the width of the inner wall of the mounting frame, resulting in larger sizes for the connectors and baffles, which is inconvenient for their installation. By adopting the above technical solution, when the drive unit moves the connector, it can drive the sliding frame to move along the length of the slide rail, thereby moving the connector. Similarly, the drive unit can drive the mounting frame to move the baffle. The sliding frame and mounting frame are frame structures, which are lightweight and easy to install, thereby reducing the required size of the connectors and baffles, making them easier to install.

[0014] Preferably, the slide rail sidewall has a slide groove, and the slide frame sidewall is provided with a roller, which is inserted into the slide groove and can roll along the inner wall of the slide groove.

[0015] Because the sliding frame has a connector and control panel on one side, its overall weight is relatively large, resulting in greater resistance on the slide rail when the sliding frame moves. By adopting the above technical solution, when the sliding frame moves along the slide rail, it simultaneously drives the roller to roll in the slide groove, converting the sliding friction into rolling friction, reducing the resistance on the slide rail when the sliding frame moves, and making the process of the control panel entering the center console easier.

[0016] Preferably, the mounting frame is rotatably connected to the drive shaft of the drive motor, and the sliding frame is rotatably connected to the drive shaft of the drive component.

[0017] Normally, the mounting frame is rotatably and fixedly connected to the drive shaft of the drive unit, and the sliding frame is fixedly connected to the drive shaft of the drive component. This means the drive shaft of the drive unit must be parallel to the moving direction of the mounting frame, and the drive shaft of the drive component must be parallel to the moving direction of the sliding frame, thus limiting the installation positions of the drive component and the drive unit. By adopting the above technical solution, the rotatable connection between the mounting frame and the drive shaft of the drive unit allows the drive shaft of the drive unit to be set at an angle to the moving direction of the mounting frame; the rotatable connection between the sliding frame and the drive shaft of the drive component allows the drive shaft of the drive component to be set at an angle to the moving direction of the sliding frame. This makes the installation positions of the drive unit and the drive component variable, reducing the limitations on their installation positions.

[0018] Preferably, the opening shape is T-shaped, and the baffle shape is adapted to the opening shape.

[0019] By adopting the above technical solution, since the width of the control panel is greater than that of the mounting base, after the steering wheel is turned to the horizontal direction, the overall main view of the control panel and the mounting base is T-shaped, and the opening is set to T-shaped, so that the steering wheel can be adapted to pass through, reducing the waste of materials caused by opening the opening too large.

[0020] Preferably, the area of ​​the baffle surface is larger than the area of ​​the through-hole cross-section, and the baffle is in contact with the inner wall of the center console; the side wall of the baffle is provided with a sealing plate, the sealing plate is adapted to the shape of the inner wall of the through-hole, and the sealing plate is inserted into the through-hole.

[0021] By adopting the above technical solution, when the drive motor pushes the baffle to move towards the through-hole, the baffle will move to be in contact with the inner wall of the center console. At the same time, the baffle will drive the sealing plate to move and insert into the through-hole, thereby cooperating with the baffle to seal the through-hole and improve the sealing performance of the through-hole.

[0022] Preferably, a connecting seat is rotatably connected to the side wall of the mounting base, and the connecting seat is hollow inside; at least two gears are rotatably connected inside the connecting seat, and adjacent gears mesh with each other; a driving disk is also rotatably connected inside the connecting seat, and the circumferential side wall of the driving disk is provided with several mating grooves, and the teeth of one of the gears are inserted into the mating grooves; one side of the driving disk passes through the connecting seat and protrudes from the side wall of the connecting seat.

[0023] The gear sidewall has a threaded hole, and the connecting seat sidewall has several through holes, which are coaxially arranged with the corresponding threaded holes. The operating disc sidewall is connected to at least two connecting bolts, which pass through the corresponding through holes and are threaded into the corresponding threaded holes.

[0024] By adopting the above technical solution, when installing the operating panel, moving the operating panel causes the two connecting bolts to pass through the corresponding through holes, allowing the two connecting bolts to be further inserted into the openings of the two threaded holes. At this time, the operator can rub the part of the drive plate protruding from the side wall of the connecting seat to drive the drive plate to rotate. The drive plate drives the mating gear to rotate through the mating groove and the teeth of the mating gear, which in turn drives the other gear to rotate. The rotation of the gear drives the threaded section in its own threaded hole to rotate, thereby causing the connecting bolt inserted in the threaded hole to be threadedly connected to the inner wall of the corresponding threaded hole. This allows the connecting bolt to be simultaneously inserted into the corresponding threaded hole, thereby driving the operating panel to move closer to the connecting seat. After the operating panel moves to be in contact with the connecting seat, the rotation of the drive plate is stopped.

[0025] Preferably, the side wall of the connecting seat is also fixedly connected to a gripping rod for fixing the connecting seat.

[0026] By adopting the above technical solution, when the operator drives the control panel to rotate with one hand, the other hand can hold the grip rod to stabilize the position of the connecting seat on the mounting base, reducing the situation where the control panel drives the connecting seat to rotate synchronously.

[0027] Preferably, the outer wall of the connector is provided with a protective shell for covering the protruding part of the drive disk.

[0028] By adopting the above technical solution, the protective cover can be rotated open when operating the drive wheel. After the drive wheel is driven, the protective cover can be rotated back onto the drive wheel to reduce the possibility of the driver accidentally touching the drive wheel and causing the connection between the drive wheel and the connecting seat to become loose.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Once the steering wheel is positioned within the center console, its impact on the interior space is reduced, thus minimizing its influence on the driver when exiting the vehicle.

[0031] 2. The combination of rollers and slides makes it easier to move the control panel into the center console.

[0032] 3. The combination of gears, drive disc, threaded holes, and connecting bolts makes the installation of the operating disc on the connecting seat faster. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0040] This application discloses a steering wheel mechanism. (Refer to...) Figure 1 The steering wheel mechanism includes a steering wheel body and a center console 1. The steering wheel body includes an operating disc 2 and a mounting base 3. A connecting seat 5 is rotatably connected to the side wall of the mounting base 3. The operating disc 2 is fixedly connected to the connecting seat 5. The connecting seat 5 is connected to the wheel via electronic steering technology. Rotating the operating disc 2 causes the connecting seat 5 to rotate, which transmits an electrical signal to the wheel rotation control system. A connecting piece 31 is rotatably connected to the side of the mounting base 3 away from the operating disc 2. The mounting base 3 is hollow inside and a motor and gear mechanism are connected inside the mounting base 3. Starting the motor can drive the gear mechanism to make the mounting base 3 rotate around the connecting piece 31.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the center console 1 has an opening 15, which is T-shaped. A mounting bracket 16 is fixedly connected to the center console 1 by bolts. The two inner side walls of the mounting bracket 16 are fixedly connected to the slide rail 12 by screws. The side wall of the slide rail 12 has a slide groove 121. A sliding frame 32 is fixedly connected to the side of the connector 31 away from the mounting base 3 by bolts. Rollers 321 are rotatably connected to the outer side walls on both sides of the sliding frame 32. The two rollers 321 are respectively inserted into the corresponding slide grooves 121. A drive component 13 is fixedly installed in the center console 1. The drive component 13 is a cylinder. The drive component 13 is rotatably connected to the side wall of the sliding frame 32 away from the connector 31.

[0042] Reference Figure 1 The two inner sidewalls of the mounting bracket 16, which are horizontally opposite each other, are also fixedly connected to the slide rails 11 by screws. A mounting frame 41 is set between the two slide rails 11, and the slide rods on both sides of the mounting frame 41 are inserted into the slide rails 11. A baffle 4 is fixedly connected to the inner sidewall of the mounting frame 41 by screws. The baffle 4 is adapted to the shape of the through 15. A drive motor 14 is fixedly installed in the center console 1. The drive motor 14 is a cylinder, and the drive shaft of the drive motor 14 is rotatably connected to the outer sidewall of the mounting frame 41.

[0043] When the driver needs to get out of the vehicle, the motor drive gear 51 mechanism in the mounting base 3 can be activated first to rotate the mounting base 3 around the connecting member 31, and at the same time, the operating panel 2 can be rotated to a horizontal position. Then, the drive member 13 can be activated. The drive shaft of the drive member 13 will pull the sliding frame 32 to move. The movement of the sliding frame 32 will cause the roller 321 to roll along the length of the slide groove 121 on the inner wall of the slide groove 121. At the same time, the sliding frame 32 will drive the connecting member 31 to move into the center console 1, thereby moving the operating panel 2 through the opening 15 into the center console 1, which can reduce the impact of the steering wheel on the driver when getting out of the vehicle.

[0044] After the control panel 2 is inserted into the center console 1, the driver can start the drive motor 14, causing the drive shaft of the drive motor 14 to push the mounting frame 41 to move along the length of the slide rail 11. The movement of the mounting frame 41 causes the baffle 4 to move towards the opening 15. After the baffle 4 moves to close the opening 15, the drive motor 14 can be stopped.

[0045] Reference Figure 1 The surface area of ​​the baffle 4 is larger than the cross-sectional area of ​​the opening 15. The side wall of the baffle 4 is provided with a sealing plate 42, which is adapted to the shape of the inner wall of the opening 15. When the drive motor 14 pushes the baffle 4 to move towards the opening 15, the baffle 4 will move to be in contact with the inner wall of the center console 1. At the same time, the baffle 4 will drive the sealing plate 42 to move and insert into the opening 15, thereby cooperating with the baffle 4 to seal the opening 15 and improve the sealing performance of the through hole 55.

[0046] Reference Figure 4 and Figure 5 The connecting seat 5 is hollow inside, and at least two gears 51 are rotatably connected to the inner side wall of the connecting seat 5. In this embodiment, there are two gears 51, and the two gears 51 mesh with each other. A driving disk 52 is also rotatably connected inside the connecting seat 5. The driving disk 52 has several mating grooves 521 on its circumferential side wall. The driving disk 52 is located on one side of one of the gears 51, and several teeth of the gear 51 near the driving disk 52 are inserted into the corresponding mating grooves 521. The side of the driving disk 52 away from the gear 51 passes through the connecting seat 5 and protrudes from the side wall of the connecting seat 5.

[0047] Reference Figure 4The side wall of gear 51 is provided with a threaded hole 511, which is coaxially arranged with the corresponding gear 51. The threaded holes 511 on the side wall of adjacent gears 51 are reverse threads. The side wall of the connecting seat 5 is provided with two through holes 55, which correspond one-to-one with the positions of the two through holes 55 and the two threaded holes 511, and are coaxially arranged with the corresponding threaded holes 511.

[0048] Reference Figure 4 Two connecting bolts are fixedly connected to the side wall of the operating panel 2. When installing the operating panel 2, moving the operating panel 2 causes the two connecting bolts 21 to pass through the corresponding through holes 55, so that the two connecting bolts 21 are further inserted into the openings of the two threaded holes 511. At this time, the operator can rub the part of the drive plate 52 protruding from the side wall of the connecting seat 5 to drive the drive plate 52 to rotate. The rotation of the drive plate 52 drives one of the gears 51 to rotate, which in turn drives the other gear 51 to rotate. The rotation of the gear 51 drives the threaded section in its own threaded hole 511 to rotate, so that the connecting bolt 21 inserted in the threaded hole 511 is threadedly connected to the inner wall of the corresponding threaded hole 511. This drives the connecting bolt 21 to be inserted into the corresponding threaded hole 511 at the same time, so that the operating panel 2 can move closer to the connecting seat 5. After the operating panel 2 moves to be in contact with the connecting seat 5, the rotation of the drive plate 52 is stopped.

[0049] Reference Figure 4 A protective shell 54 is rotatably connected to the outer wall of the connecting seat 5. The protective shell 54 is fastened to the part of the drive disc 52 that protrudes from the side wall of the connecting seat 5. When operating the drive disc 52, the protective shell 54 can be rotated to open. After driving the operating disc 2, the protective shell 54 can be rotated to cover the drive disc 52 again, so as to reduce the situation where the driver accidentally touches the drive disc 52 when using the steering wheel, causing the connection between the operating disc 2 and the connecting seat 5 to become loose.

[0050] Reference Figure 4 The side wall of the connecting seat 5 is fixedly connected to the gripping rod 53 by screws. When the operator drives the operating plate 2 to rotate with one hand, the other hand can hold the gripping rod 53 to stabilize the position of the connecting seat 5 on the mounting base 3 and reduce the situation where the operating plate 2 drives the connecting seat 5 to rotate synchronously.

[0051] The implementation principle of a steering wheel mechanism in this application embodiment is as follows:

[0052] When the driver needs to get out of the vehicle, the motor-driven gear 51 mechanism in the mounting base 3 can be activated first, causing the mounting base 3 to rotate around the connecting member 31, and simultaneously causing the operating panel 2 to rotate to a horizontal position. Then, the drive member 13 is activated. The drive shaft of the drive member 13 pulls the sliding frame 32 to move. The movement of the sliding frame 32 causes the roller 321 to roll along the length of the slide groove 121 on the inner wall of the slide groove 121. At the same time, the sliding frame 32 causes the connecting member 31 to move into the center console 1, thereby causing the operating panel 2 to move through the opening 15 and into the center console 1. Then, the drive motor 14 is activated, causing the drive shaft of the drive motor 14 to push the mounting frame 41 to move along the length of the slide rail 11. The movement of the mounting frame 41 causes the baffle 4 to move towards the opening 15. After the baffle 4 moves to the point where the sealing plate 42 is inserted into the opening 15, the steering wheel is hidden. This reduces the space occupied by the steering wheel in the vehicle and reduces the impact of the steering wheel on the driver when getting out of the vehicle.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
