Description

Technical Field

[0001] This invention relates to steering wheel technology, and more particularly to a high-strength, lightweight EPP steering wheel structure. Background Technology

[0002] In recent years, with the development of smart cockpits, users' demands for in-vehicle displays have gradually increased, leading to the emergence of solutions that add screens to the steering wheel. This solution allows users to access driving information more closely, enabling them to see vehicle information intuitively even at high speeds. It also increases in-vehicle interaction methods and enhances the sense of technology. Integrating screens on the steering wheel has become a clear direction in the development of smart cockpit display solutions.

[0003] The current arrangement involves a fixed connection between the screen and the steering wheel. However, the screen may vary depending on the model version. Furthermore, when replacing the screen later, the entire fixed part in the center of the steering wheel needs to be disassembled before the screen can be removed and replaced. This not only requires a lot of time to disassemble, but also carries the risk of clips breaking during the disassembly process, thus increasing the difficulty of disassembly and the replacement cost.

[0004] CN116679896A discloses a vehicle multi-screen control method, electronic device, storage medium, and vehicle. The screen is set on the steering wheel, but it is inconvenient for later disassembly and assembly. At the same time, it is not integrated with the steering wheel, which can easily affect the driver's operation. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this invention proposes a high-strength, lightweight EPP steering wheel structure.

[0006] The technical solution of this invention is implemented as follows:

[0007] A high-strength, lightweight EPP steering wheel structure, characterized in that it comprises:

[0008] Steering wheel body,

[0009] A press-type body is located in the center of the steering wheel body. The press-type body consists of a housing, an outer cover, and a display screen mounted on the outer cover. The housing has an internal hollowed-out mounting area, within which an airbag and horn assembly are installed. The outer cover has a mounting opening to accommodate the display screen. The interior of the outer cover contains symmetrical fixing components, each including a pusher, a limiting seat, and an elastic element. The pusher is hinged to the limiting seat via a pivot. The elastic element is detachably mounted on the limiting seat. One end of the pusher has a protrusion, and the other end has a pusher portion with an arc-shaped opening. The bottom of the display screen has an arc-shaped portion that mates with the arc-shaped opening. When the pusher is subjected to force, the protrusion pushes the elastic element to deform under force, and the pusher pushes the display screen out of the mounting opening.

[0010] The outer cover has downwardly extending lips on both sides. Each lip has a through hole and symmetrically arranged limiting openings. A limiting member for maintaining the connection between the outer cover and the shell is installed on the lip. The limiting member consists of a limiting plate and a force-bearing plate. The upper ends of the limiting plate and the force-bearing plate are connected by a curved section. The limiting plate has limiting arms on both sides that cooperate with the limiting openings. The force-bearing plate has a pressing part that is perpendicular to the force-bearing plate and is disposed in the through hole. The force-bearing plate also has an extension section that is parallel to the pressing part. The lower end of the extension section has an extension arm. The lower end of the extension arm has a hook. The lower end of the hook has a first inclined surface. The upper end of the hook has a first flat surface. The inner wall of the shell has a limiting body that cooperates with the hook. The upper end of the limiting body has a second inclined surface that cooperates with the first inclined surface. The lower end of the limiting body has a second flat surface that cooperates with the first flat surface.

[0011] In this invention, the pusher is further provided with a magnet, which is located at the rear end of the protrusion.

[0012] In this invention, the pusher has an arc-shaped head in the middle, the arc-shaped head has a strip-shaped hole in the middle, and the rotating shaft is disposed in the strip-shaped hole.

[0013] In this invention, the limiting seat is composed of a connecting part and a support part located at both ends of the connecting part. The connecting part is provided with an inclined limiting surface. The lower end of the connecting part forms a first receiving area for limiting the pushing member, and the upper end forms a second receiving area for receiving the elastic member.

[0014] In this invention, the support portion is provided with a receiving opening, and the elastic element is composed of a fixing portion and arc-shaped segments and contact segments disposed on both sides of the fixing portion. A compression area is formed between the arc-shaped segments, and an extension segment is provided on the contact segment, which is placed in the receiving opening.

[0015] In this invention, half the width of the compression region is greater than the length of the extension section.

[0016] In this invention, the limiting arm is provided with an elastic arm, and an elastic region is formed between the limiting arm and the elastic arm.

[0017] In this invention, a limiting body is provided in the limiting opening, the limiting body is used to block the elastic arm, the distance between the limiting body and the inner wall of the limiting opening is H1, and the maximum opening and closing distance between the elastic arm and the limiting arm in the natural state is H2, where H1 < H2.

[0018] In this invention, the limiting plate is provided with a notch to accommodate the extension section, and the upper end of the extension arm is located in the notch.

[0019] In this invention, the distance between the force-bearing plate and the limiting plate is H3, the hook body is provided with a first vertical surface, the limiting body is provided with a second vertical surface that cooperates with the first vertical surface, and after the hook body contacts the limiting body, the distance between the first vertical surface and the second vertical surface is H4, where H3 > H4.

[0020] The high-strength, lightweight EPP steering wheel structure of this invention has the following advantages: The high-strength, lightweight EPP steering wheel structure is ingeniously designed and compact. The screen is fixed through a hidden design, eliminating the need for screws and preventing easy disassembly by unauthorized personnel. Simultaneously, the detachable limiting component structure ensures the connection stability between the outer cover and the housing, avoiding the risk of limiting component breakage and reducing subsequent maintenance costs.

Detailed Implementation

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] like Figures 1 to 14As shown, this high-strength, lightweight EPP steering wheel structure of the present invention includes a steering wheel body 1 and a pressing body 2, with the pressing body 2 positioned in the center of the steering wheel body 1. The pressing body 2 consists of a housing 3, an outer cover 4, and a display screen 5 mounted on the outer cover 4. The housing 3 has a hollowed-out interior forming a mounting area 6, within which an airbag and a horn assembly are mounted. This allows the pressing body 2 to integrate the airbag, horn assembly, and display screen 5 into a single unit.

[0038] The housing 3 has a fixing opening 7 and a baffle plate 8, which restricts the position of the outer cover 4 to prevent it from detaching from the housing 3. Additionally, a support plate 9 is provided on the housing 3, located below the fixing opening 7 and perpendicular to the baffle plate 8. The support plate 9 supports the outer cover 4 and secures it to the housing 3.

[0039] The outer cover 4 has a mounting opening 10 for accommodating the display screen 5. The mounting opening 10 includes a guide ramp 11 to facilitate the installation of the display screen 5, ensuring accurate insertion and fixation. The outer cover 4 contains symmetrical fixing components 12, which secure the display screen 5 within the mounting opening 10. A strong external magnet 13 is required to remove the display screen 5 from the mounting opening 10. This method eliminates the need for screws or clips to fix the screen, facilitating the installation and removal of the display screen 5. It also reduces the need for non-professional installation and removal, minimizing improper handling and extending the vehicle's lifespan.

[0040] The fixing assembly 12 includes a pusher 14, a limiting seat 15, and an elastic member 16. The pusher 14 is hinged to the limiting seat 15 via a pivot 17, and the elastic member 16 is detachably mounted on the limiting seat 15. The pusher 14 also has a magnet 18 located at the rear end of the protrusion 19. The pusher 14 has an arc-shaped head 20 in its center, with a slotted hole 21 in the center, and the pivot 17 is positioned within the slotted hole 21. When the pusher 14 is pushed by a strong magnet 13, the magnet 18 on the pusher 14 is kept under a relatively strong magnetic force, thereby causing the pushing part 22 on the pusher 14 to push the display screen 5 out of the mounting opening 10.

[0041] When in use, the strong magnet 13 needs to be placed close to the outer cover 4 with the side of the magnet 18 facing the inner wall of the outer cover 4, so that the strong magnet 13 pushes the magnet 18 under strong magnetic force. Through the principle of like poles repelling, the magnet 18 drives the pusher 14 to rotate on the rotating shaft 17. The magnetic force of the strong magnet 13 can push the pusher 14, which in turn pushes the elastic member 16 to bend. When the strong magnet 13 is removed, the elastic force of the elastic member 16 can reset the pusher 14, keeping the magnet 18 in contact with the inner wall of the outer cover 4.

[0042] The limiting seat 15 consists of a connecting part 23 and support parts 24 located at both ends of the connecting part 23. The connecting part 23 is provided with an inclined limiting surface 25, which can limit the rotation angle of the pushing member 14. The lower end of the connecting part 23 forms a first receiving area 26 that limits the pushing member 14, and the upper end forms a second receiving area 27 that receives the elastic member 16.

[0043] The support portion 24 is provided with a receiving opening 28. The elastic member 16 consists of a fixing portion 29 and arc-shaped segments 30 and contact segments 31 provided on both sides of the fixing portion 29. A compression region 32 is formed between the arc-shaped segments 30. An extension segment 33 is provided on the contact segment 31 and is placed in the receiving opening 28. Half of the width of the compression region 32 is greater than the length of the extension segment 33.

[0044] When installing the elastic element 16, press the arc-shaped segment 30 towards the center of the compression area 32, causing the contact segments 31 on both sides to move, and simultaneously causing the extension segment 33 to move out of the receiving port 28, so that the elastic element 16 can be removed. In addition, the fixing part 29 can also enhance the elasticity of the elastic element 16, and can better restrain the pushing member 14.

[0045] One end of the pusher 14 has a protrusion 19, and the other end has a pusher 22. The pusher 22 has an arc-shaped opening 34, and the bottom of the display screen 5 has an arc-shaped portion 35 that mates with the arc-shaped opening 34. When the pusher 14 is subjected to force, the protrusion 19 pushes the elastic member 16 to deform under force, and the pusher 22 pushes the display screen 5 out of the mounting port 10.

[0046] The outer cover 4 has downwardly extending lips 36 on both sides, and each lip 36 has a through hole 37 and symmetrically arranged limiting openings 38. A limiting member 39 for maintaining the connection between the outer cover 4 and the housing 3 is installed on the lip 36. The limiting member 39 consists of a limiting plate 40 and a force-bearing plate 41. The upper ends of the limiting plate 40 and the force-bearing plate 41 are connected by a bending section 42, which ensures that the force-bearing plate 41 can return to its original shape after being pressed.

[0047] The limiting plate 40 has limiting arms 43 on both sides that cooperate with the limiting opening 38. Each limiting arm 43 has an elastic arm 44, forming an elastic region 45 between the limiting arms 43 and the elastic arm 44. A limiting body 46 is provided in the limiting opening 38 to block the elastic arm 44. The distance between the limiting body 46 and the inner wall of the limiting opening 38 is H1. The maximum opening and closing distance between the elastic arm 44 and the limiting arm 43 in its natural state is H2, where H1 < H2. The limiting plate 40 has a notch 48 to accommodate the extension section 47, and the upper end of the extension arm 49 is located in the notch 48.

[0048] The width of the limiting opening 38 is exactly matched with the distance H2 between the elastic arm 44 and the limiting arm 43. By adding the limiting body 46, the width of the limiting opening 38 is reduced, which can better limit the elastic arm 44 and fix the limiting part 39 on the outer cover 4.

[0049] The force-bearing plate 41 is provided with a pressing part 50 that is perpendicular to the force-bearing plate 41, and the pressing part 50 is disposed in the through hole 37. The force-bearing plate 41 is also provided with an extension section 47 that is parallel to the pressing part 50, and the lower end of the extension section 47 is provided with an extension arm 49, and the lower end of the extension arm 49 is provided with a hook 51.

[0050] The lower end of the hook body 51 is provided with a first inclined surface 52, the upper end of the hook body 51 is provided with a first flat surface 53, and the inner wall of the shell 3 is provided with a limiting body 54 that cooperates with the hook body 51. The upper end of the limiting body 54 is provided with a second inclined surface 55 that cooperates with the first inclined surface 52, and the lower end of the limiting body 54 is provided with a second flat surface 56 that cooperates with the first flat surface 53.

[0051] When the outer cover 4 moves the limiting member 39 downward, the first inclined surface 52 on the hook body 51 can be kept in contact with the second inclined surface 55, and then the first vertical surface 57 and the second vertical surface 58 can be made to contact. Finally, the first plane 53 and the second plane 56 can be made to contact. The position of the hook body 51 is restricted by the limiting body 54, thereby fixing the outer cover 4 to the shell 3.

[0052] By designing the limiting component 39 and the outer cover 4 separately during manufacturing, it is possible to replace the limiting component 39 later without having to replace the outer cover 4.

[0053] The distance between the force-bearing plate 41 and the limiting plate 40 is H3. The hook body 51 is provided with a first vertical surface 57, and the limiting body 54 is provided with a second vertical surface 58 that cooperates with the first vertical surface 57. After the hook body 51 contacts the limiting body 54, the distance between the first vertical surface 57 and the second vertical surface 58 is H4, where H3 > H4. When the pressing part 50 is pushed, the pressing part 50 can push the force-bearing plate 41, keeping the b-surface and a-surface in contact, thereby pushing the hook body 51 at the lower end of the extension arm 49 to disengage from the limiting body 54.

[0054] Of course, in practice, decorative paper can be attached to the through hole 37 to seal it and prevent non-professionals from accidentally disassembling it.

[0055] The fixing component 12 can be used to quickly assemble and disassemble the display screen 5, while the limiting component 39 can remove the entire outer cover 4 to replace and maintain the internal components of the housing 3, thus avoiding the risk of buckle breakage in the prior art.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
