Description

Technical Field

[0001] This utility model relates to the field of five-way wheel button technology, specifically a five-way wheel button with a rotating and pressing structure. Background Technology

[0002] A car steering wheel mainly consists of a circumference and spokes connecting it to the steering column. Depending on the number of spokes, steering wheels can be categorized as three-spoke or four-spoke. Some automotive function buttons are typically integrated into the spokes, near the circumference. This design allows the driver to interact with the machine while keeping both hands on the circumference of the steering wheel. This is the original design principle behind multi-function steering wheels.

[0003] With the increasing intelligence of automotive in-vehicle control systems, the number of buttons required is growing. Intentionally reducing the size of buttons to accommodate more functions on the steering wheel may be detrimental to usability. Conversely, placing buttons far from the driver's hand area forces the driver to shift their gaze and hands to find and use them, potentially creating a safety hazard. Therefore, the design and placement of buttons on the steering wheel is a technical problem that needs to be solved.

[0004] Existing button designs are limited in variety and are typically designed as direct-pressure mechanisms, which can occupy limited button space. Existing buttons include a scroll wheel and buttons around it. A five-way scroll wheel refers to a scroll wheel that can be scrolled forward and backward, pressed left and right, and pressed vertically downward. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a five-way wheel button with a rotating and pressing structure, which has the advantage of saving space and solves the problem of insufficient space caused by the increasing number of buttons.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a five-way wheel button with a rotating and pressing structure, wherein a roller is provided on the button, the roller and the roller bracket are connected, and a rotating component is provided on the roller bracket. The rotating component has a T-shaped structure and a ball in the middle. The rotating component is installed in a rotating groove on the inner side of the outer shell to prevent the rotating component from moving laterally. The ball rolls in the rotating groove. The rotating groove is vertically interfering with the side rod at the position of the corresponding side rod to limit the vertical movement distance of the roller bracket on both sides. The roller bracket can be moved left and right along the rotation axis of the rotating component, thereby realizing the function of the left and right button feel of the roller.

[0009] Preferably, the bottom of the roller bracket is provided with two symmetrical side pressure blocks on one side of the corresponding rotating part, and a lower pressure block is provided on the rotation axis of the rotating part on the other side. A top rod is provided at the bottom of the two side pressure blocks and the lower pressure block. When the roller bracket is pressed left and right, the side pressure block on the lower side presses down the corresponding top rod. When the roller bracket is pressed vertically, the lower pressure block presses down the corresponding top rod with the ball as the fulcrum.

[0010] Preferably, each push rod has a pressure sensing block at its bottom, and each pressure sensing block is mounted on the circuit board of the circuit board assembly. The outside of the circuit board is covered with a rubber film for waterproofing.

[0011] Preferably, the roller bracket is further provided with a protrusion at the position of the lower pressure block. The protrusion is installed in a sliding groove on the inner side of the housing and slides up and down in the sliding groove to prevent the lower pressure block of the roller bracket from moving left and right.

[0012] Preferably, the roller is connected to the rotating shaft and drives the drive wheel to rotate. The drive wheel on the roller meshes with the transmission gear, and the transmission gear meshes with one end of the ratchet. The ratchet is fixed to the bottom of the roller bracket and is provided with blades. When the roller rotates, the blades are driven to rotate synchronously through the drive wheel, the transmission gear and the ratchet.

[0013] Preferably, a sensor is provided at the bottom of the blade. The sensor is installed on the circuit board in the circuit board assembly. When the blade rotates, it passes through the sensor. The sensor senses the rotation direction and amount of the blade through optical sensing, thereby determining the rotation direction and amount of the roller.

[0014] Preferably, the roller bracket consists of a roller bracket cover plate and a roller bracket base. The top of the roller bracket cover plate has two semicircles with a gap between them. The roller is installed between the two semicircles. By pressing the two semicircles on the roller bracket cover plate left and right, the roller bracket can be moved left and right along the rotation axis of the rotating component, thus avoiding loosening of the connection due to direct pressing of the roller.

[0015] Preferably, the inner side of the housing is provided with through holes at the positions corresponding to each push rod, and each push rod is locked in the through hole to fix the position of the push rod so that the push rod is always aligned with the pressure sensing block at the bottom, so as to avoid deviation when pressing and thus prevent the switch from being triggered.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a five-way wheel button with a rotating pressing structure, which has the following advantages:

[0018] 1. This five-way wheel button with a rotating and pressing structure connects the roller to the roller bracket. The roller bracket is fixed to the rotating groove on the inner side of the housing by a rotating component. The rotating component includes a ball in the middle and side rods on both sides. The ball fits into the rotating groove, so that when the roller bracket is pressed down vertically, the roller bracket rotates and presses down on the other side with the ball as the fulcrum. There is a gap between the side rods and the rotating groove, so that the roller bracket can be pressed left and right, realizing the left and right and downward pressing feel of the roller.

[0019] 2. This five-way wheel button with a rotating pressing structure uses an active wheel between the rollers to drive a transmission gear. The bottom of the transmission gear meshes with a ratchet. When the blades on the ratchet rotate, they pass through a sensor. The sensor senses the rotation direction and amount of the blades through optical sensing, thereby determining the rotation direction and amount of the rollers and realizing the detection of the rollers' forward and backward rolling.

[0036] Example 1:

[0037] This embodiment provides a five-way wheel button with a rotating pressing structure, which has the following technical features.

[0038] Please see Figure 1-8A five-way wheel button with a rotating and pressing structure includes a housing 1 and a rocker button 3 mounted on the top of the housing 1. A roller 2 is set in the middle of the rocker button 3. The roller 2 is connected to a roller bracket 4. A rotating component 40 is set on the roller bracket 4. The rotating component 40 has a T-shaped structure and a ball 401 in the middle. The rotating component 40 is installed in a rotating groove 11 inside the housing 1 to prevent the rotating component 40 from moving laterally. The ball 401 rolls in the rotating groove 11. The rotating groove 11 is vertically interfering with the side rod 402 at the position corresponding to the side rod 402 to limit the vertical movement distance of the roller bracket 4 on both sides. The roller bracket 4 can be moved left and right along the rotation axis of the rotating component 40, thereby realizing the function of the left and right button feel of the roller 2.

[0039] Specifically, a spring is provided at the bottom center of the roller bracket 4 for support and reset after being pressed.

[0040] Example 2:

[0041] This embodiment provides a five-way wheel button with a rotating and pressing structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0042] like Figure 3 As shown, the bottom of the roller bracket 4 is provided with two symmetrical side pressure blocks 441 on one side of the corresponding rotating part 40, and a lower pressure block 442 is provided on the rotation axis of the rotating part 40 on the other side. A top rod 451 is provided at the bottom of both side pressure blocks 441 and the lower pressure block 442.

[0043] With the above technical solution, when the roller bracket 4 is pressed down from the left and right, the side pressing block 441 on the lower side presses down the corresponding top rod 451. When the roller bracket 4 is pressed down vertically, the lower pressing block 442 presses down the corresponding top rod 451 with the ball 401 as the fulcrum.

[0044] Furthermore, each push rod 451 is provided with a pressure sensing block 452 at its bottom. Each pressure sensing block 452 is mounted on the circuit board of the circuit board assembly 5. The outside of the circuit board is covered with a rubber film for waterproofing.

[0045] Furthermore, the roller bracket 4 is provided with a protrusion 43 at the position of the lower pressure block 442. The protrusion 43 is installed in the slide groove 12 inside the housing 1. The protrusion 43 slides up and down in the slide groove 12 to prevent the lower pressure block 442 of the roller bracket 4 from moving left and right on one side.

[0046] Furthermore, the inner side of the outer casing 1 is provided with through holes at the positions corresponding to each push rod 451. Each push rod 451 is locked in the through hole to fix the position of the push rod 451, so that the push rod 451 can only move up and down, and the push rod 451 is always aligned with the pressure sensing block 452 at the bottom, so as to avoid deviation when pressing, which would cause the switch to fail to be triggered.

[0047] Example 3:

[0048] This embodiment provides a five-way wheel button with a rotating and pressing structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0049] like Figure 4 As shown, roller 2 is connected to the rotating shaft and drives the drive wheel to rotate. The drive wheel on roller 2 meshes with the transmission gear 21. The transmission gear 21 meshes with one end of ratchet 22. The ratchet 22 is fixed to the bottom of roller bracket 4. The ratchet 22 is provided with blades 23.

[0050] Through the above technical solution, when the roller 2 rotates, it drives the blade 23 to rotate synchronously through the drive wheel, transmission gear 21 and ratchet 22.

[0051] like Figure 4 As shown, a sensor 24 is provided at the bottom of the blade 23, and the sensor 24 is mounted on the circuit board inside the circuit board assembly 5.

[0052] With the above technical solution, when the blade 23 rotates, it passes through the sensor 24. The sensor 24 senses the rotation direction and amount of the blade 23 through optical sensing, thereby determining the rotation direction and amount of the roller 2.

[0053] Example 4:

[0054] This embodiment provides a five-way wheel button with a rotating and pressing structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] like Figure 3-4 As shown, the roller bracket 4 consists of a roller bracket cover plate 41 and a roller bracket base 42. The top of the roller bracket cover plate 41 is provided with two semicircles with a gap between them.

[0056] With the above technical solution, the roller 2 is installed in the middle of two semicircles. By pressing the two semicircles on the roller bracket cover plate 41 from the left and right, the roller bracket 4 is moved left and right along the rotation axis of the rotating part 40, avoiding the connection from being loosened by directly pressing the roller 2.

[0057] Working principle: A rotating component 40 is set on the roller bracket 4. The rotating component 40 is T-shaped and has a ball 401 in the middle. When the rotating component 40 is locked in the rotating groove 11 on the inner side of the outer shell 1, the ball 401 is attached to the inner wall of the rotating groove 11. Therefore, when the roller bracket 4 is pressed down, the roller bracket 4 will rotate downward with the ball 401 as the fulcrum. When the roller bracket 4 is pressed to the left or right, since there is a gap in the vertical direction between the side rods 402 on both sides of the ball 401 and the rotating groove 11, the roller bracket 4 will rotate left and right around the rotation axis of the rotating component 40, thereby pressing the buttons on the left and right sides of the roller bracket 4. In addition, the roller 2 rolls back and forth in two directions, for a total of five directions.

[0058] In summary, this five-way wheel button with a rotating and pressing structure connects the roller 2 to the roller bracket 4. The roller bracket 4 is fixed to the rotating groove 11 inside the outer casing 1 by a rotating component 40. The rotating component 40 includes a central ball 401 and two side rods 402. The ball 401 fits into the rotating groove 11, so that when the roller bracket 4 is pressed vertically downward, the roller bracket 4 rotates and presses down on the other side with the ball 401 as the fulcrum. There is a gap between the side rods 402 and the rotating groove 11, so that the roller bracket 4 can be pressed left and right, realizing the left and right and downward pressing feel of the roller 2.

[0059] This five-way wheel button with a rotating pressing structure uses an active wheel between the rollers 2 to drive a transmission gear 21. The bottom of the transmission gear 21 meshes with a ratchet 22. When the blade 23 on the ratchet 22 rotates, it passes through a sensor 24. The sensor 24 senses the rotation direction and amount of the blade 23 through optical sensing, thereby determining the rotation direction and amount of the roller 2 and realizing the forward and backward rolling detection of the roller 2.

[0060] The five-way wheel button with a rotating pressing structure has the roller 2 installed between the roller bracket cover plate 41 and the roller bracket base 42. The top of the roller bracket cover plate 41 has two semicircles, and the top of the roller 2 is located between the two semicircles. When pressing the roller bracket 4 left or right, it can press the semicircles on the roller bracket cover plate 41, avoiding the connection on the roller 2 from being loosened by pressing the roller 2 directly.
