Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically, to a four-way switch button device and a vehicle. Background Technology

[0002] In the current technology of integrated steering wheel panels, the button structure that enables different functions by pressing in four directions generally has the following structural defects: Since it only relies on the single-axis structure in the middle for support in the long or short direction, the diagonal lifting amount opposite to the button and the pressing amount are basically the same when the button is pressed. This relatively large lifting amount not only makes it difficult to achieve accurate tactile feedback, but also affects the customer's sense of perception and the product quality.

[0003] Therefore, there is a need to provide an improved four-way switch button device and vehicle to at least partially address the drawbacks of the prior art. Utility Model Content

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, a four-way switch button device is provided. The four-way switch button device includes a keycap, a button bracket, and a guide frame. The button bracket is fixedly connected to the keycap and is provided with a pair of first limiting members and a pair of second limiting members. The pair of first limiting members are symmetrically arranged with respect to the center of the button bracket in the width direction of the keycap, and the pair of second limiting members are symmetrically arranged with respect to the center of the button bracket in the width direction of the keycap. The guide frame is provided with a pair of first limiting mating members and a pair of second limiting mating members. The pair of first limiting members are respectively movably engaged with the pair of first limiting mating members, and the pair of second limiting members are respectively movably engaged with the pair of second limiting mating members. The first limiting members and the second limiting members are positioned on different sides of the center of the button bracket in the length direction of the keycap.

[0005] Optionally, the guide frame includes a first limiting part and a second limiting part disposed opposite to each other, and the line connecting the center of the first limiting part and the center of the second limiting part is parallel to the length direction of the keycap.

[0006] Optionally, the center distance between the first limiting member and the second limiting member in the length direction of the keycap is L2, the distance between the first limiting member and the edge of the first key bracket of the key holder in the length direction of the keycap is L1, and the distance between the second limiting member and the edge of the second key bracket of the key holder in the length direction of the keycap is L3, wherein L2 > L1 and L1 = L3.

[0007] Optionally, the first limiting member and the second limiting member are configured as limiting protrusions, and the first limiting mating member and the second limiting mating member are configured as limiting grooves. At least a portion of the first limiting member in the form of a limiting protrusion is movably accommodated in the first limiting mating member in the form of a limiting groove, and at least a portion of the second limiting member in the form of a limiting protrusion is movably accommodated in the second limiting mating member in the form of a limiting groove.

[0008] Optionally, the four-way switch button device also includes a reset elastic element and a circuit board. The reset elastic element is disposed between the circuit board and the guide frame. When the keycap is not pressed, the reset elastic element is in a natural state or a pre-compressed state.

[0009] Optionally, the reset elastic element is an arc-shaped spring.

[0010] Optionally, the guide frame is provided with a light-transmitting post with a through hole, and the keycap is provided with a light-transmitting part in the area corresponding to the light-transmitting post.

[0011] Optionally, the key support can be detachably attached to the keycap.

[0012] Optionally, the button bracket is provided with a third limiting portion located at the edge of the first button bracket and a fourth limiting portion located at the edge of the second button bracket, and the guide frame is provided with a third limiting engagement portion for accommodating the third limiting portion and a fourth limiting engagement portion for accommodating the fourth limiting portion.

[0013] In another aspect of this invention, a vehicle is provided that includes the aforementioned four-way switch button device.

[0014] This invention utilizes a dual-axis mechanism along the length of the keycap. When the key is pressed, the axis of rotation is located further from the pressing point, creating a longer effective pressing arm and a shorter lifting arm. This results in a pressing stroke greater than the diagonal lifting distance opposite the pressing point, reducing the overall panel lifting amplitude by more than 50% compared to existing technologies. This design effectively controls the diagonal lifting amount with a smaller pressing stroke, improving the flatness of the key during operation and optimizing the user's sensory experience and product texture. Furthermore, the reduction in planar lifting helps avoid common product quality issues such as noticeable black edges, light leakage, and excessive structural wobbling, improving the overall reliability and aesthetics of the four-way switch key device.

[0021] According to a first aspect of the present invention, a four-way switch button device 10 is provided. Figure 1 This is a perspective view of the keycap 100 and key support 200 of a four-way switch button device 10 according to an embodiment of the present invention, wherein the key support 200 is connected to the keycap 100. Figure 2 This is a perspective view of the button bracket 200 and guide frame 300 of a four-way switch button device 10 according to an embodiment of the present invention, wherein the button bracket 200 is mounted on the guide frame 300. Figure 3 A schematic diagram of a four-way switch button device 10 according to an embodiment of the present invention is shown in cross-sectional view. Figure 4 Shown in the form of a magnified view Figure 2 The diagram shows a cross-sectional view of region A along the YZ plane.

[0022] To facilitate understanding of this utility model, the directions mentioned herein are defined as follows: In this embodiment, the keycap 100 of the four-way switch button device 10 is generally elongated, specifically quadrilateral. The length direction of the keycap 100 is defined as parallel to the X direction, the width direction as parallel to the Y direction, and the thickness direction as parallel to the Z direction. The X direction is perpendicular to the Y direction, and the Z direction is perpendicular to both the X and Y directions. It should be understood that in other embodiments not shown in this utility model, the keycap 100 can also be any other suitable shape. For example, the keycap 100 can have a circular or elliptical shape.

[0023] like Figures 1 to 4 As shown, the four-way switch button device 10 includes a keycap 100, a button support 200, and a guide frame 300. For example... Figure 1 and Figure 4As shown, the keycap 100 has a first keycap surface 110 and a second keycap surface 120 arranged opposite to each other. The first keycap surface 110 is provided with a four-way key mark, thereby forming four independently pressable areas on the first keycap surface 110 for easy user identification and operation. The second keycap surface 120 is used for internal structural connections, for example, to achieve reliable assembly with the key support 200 as will be described in detail later, ensuring balance and stability during key pressing.

[0024] The key bracket 200 is fixedly connected to the keycap 100. It should be noted that the term "fixed connection" in this article refers to a fixed relative position, that is, the relative position is fixed during installation. It can refer to either a non-removable fixed connection or a detachable fixed connection.

[0025] Specifically, in this embodiment, the key support 200 is detachably connected to the second keycap surface 120 of the keycap 100. For example... Figure 1 As shown, the second keycap surface 120 of the keycap 100 is provided with a first positioning portion 121 and a second positioning portion 122. Each of the first positioning portion 121 and the second positioning portion 122 is designed as a sheet-like protruding post structure extending from the second keycap surface 120 along the Z direction, and each is provided with a positioning hole. The line connecting the center of the positioning hole of the first positioning portion 121 and the center of the positioning hole of the second positioning portion 122 is parallel to the X direction. Correspondingly, the key support 200 is provided with positioning protrusions (not shown) arranged opposite to each other in the X direction, such that the oppositely arranged positioning protrusions of the key support 200 can be respectively accommodated in the positioning holes of the first positioning portion 121 and the second positioning portion 122. Furthermore, the second keycap surface 120 of the keycap 100 is provided with a third positioning portion 123 and a fourth positioning portion 124. Each of the third positioning portion 123 and the fourth positioning portion 124 is designed as a boss structure extending from the second keycap surface 120 along the Z direction, and the cross-section of the boss structure in the XY plane has a "T" shape. Correspondingly, the key support 200 is provided with a first positioning groove 201 and a second positioning groove 202, so that the third positioning portion 123 and the fourth positioning portion 124 of the keycap 100 can be engaged with the first positioning groove 201 and the second positioning groove 202 respectively by means of mechanical interlocking or interference fit. In this way, the relative displacement between the keycap 100 and the key support 200 is effectively limited, and a stable connection between the keycap 100 and the key support 200 is achieved, ensuring that the keycap 100 and the key support 200 always maintain synchronous movement when frequently pressed or when force is applied in different directions. Optionally, the line connecting the center of the third positioning part 123 and the center of the fourth positioning part 124 is parallel to the Y direction, and the first positioning groove 201 and the second positioning groove 202 are respectively arranged opposite to each other in the Y direction.

[0026] It should be understood that, in other embodiments not shown in this utility model, the connection between the keycap 100 and the key support 200 can also be achieved using common assembly methods such as snap-fit, screw fixing, or adhesive bonding, as long as it is ensured that the keycap 100 can smoothly and reliably transmit the force to the key support 200 when pressed from all directions. Furthermore, the key support 200 can also be integrally formed with the keycap 100.

[0027] like Figure 1 As shown, the key support 200 is provided with a pair of first limiting members 211 and a pair of second limiting members 212. The pair of first limiting members 211 are symmetrically arranged with respect to the center of the key support 200 in the width direction of the keycap 100, and the pair of second limiting members 212 are symmetrically arranged with respect to the center of the key support 200 in the width direction of the keycap 100.

[0028] Specifically, in this embodiment, the button bracket 200 adopts a centrally symmetrical structure and has a first bracket side 210 and a second bracket side 220 arranged opposite to each other in the Y direction. One of the paired first limiting members 211 is disposed on the first bracket side 210, and the other of the paired first limiting members 211 is disposed on the second bracket side 220. The paired first limiting members 211 are symmetrically arranged in the Y direction with respect to the center of the button bracket 200; that is, the line connecting the centers of the two first limiting members 211 (i.e., the virtual rotation axis Y1) is parallel to the Y direction. Similarly, two paired second limiting members 212 are respectively disposed on the first bracket side 210 and the second bracket side 220, and are symmetrically arranged in the Y direction with respect to the center of the button bracket 200. The line connecting the centers of the paired second limiting members 212 (i.e., the virtual rotation axis Y2) is parallel to the Y direction. In this configuration, each of the first support side 210 and the second support side 220 is provided with a first limiting member 211 and a second limiting member 212.

[0029] The guide frame 300 is provided with a pair of first limiting mating parts 311 (see Figure 4The guide frame 300 has a first guide side 310 and a second guide side 320 disposed opposite each other in the Y direction. One of the two paired first limiting fittings 311 is disposed on the first guide side 310, and the other of the two paired first limiting fittings 311 is disposed on the second guide side 320. The two paired first limiting fittings 311 are symmetrically disposed in the Y direction relative to the center of the guide frame 300, that is, the line connecting the centers of the two first limiting fittings 311 is parallel to the Y direction. Similarly, two paired second limiting fittings are respectively disposed on the first guide side 310 and the second guide side 320, and are symmetrically disposed in the Y direction relative to the center of the guide frame 300, such that the line connecting the centers of the two paired second limiting fittings is parallel to the Y direction.

[0030] The pair of first limiting members 211 are respectively movably engaged with the pair of first limiting mating members 311, and the pair of second limiting members 212 are respectively movably engaged with the pair of second limiting mating members, so that the key bracket 200 and the keycap 100 fixedly connected to the key bracket 200 are movably mounted on the guide frame 300.

[0031] like Figure 4 As shown, in this embodiment, the first limiting member 211 and the second limiting member 212 are configured as limiting protrusions, and the first limiting mating member 311 and the second limiting mating member are configured as limiting grooves. At least a portion of the first limiting member 211 in the form of a limiting protrusion is movably accommodated in the first limiting mating member 311 in the form of a limiting groove, and at least a portion of the second limiting member 212 in the form of a limiting protrusion is movably accommodated in the second limiting mating member in the form of a limiting groove.

[0032] Specifically, the following text takes the first limiting fitting part 311 as an example and refers to... Figure 4 To provide a detailed description, such as... Figure 4As shown, in this embodiment, the first limiting member 311 has an elongated shape extending along the Z direction. Its inner sidewall includes a first limiting member limiting surface 311A ​​and a second limiting member limiting surface 311B disposed opposite each other in the Z direction. A portion of the first limiting member 211 of the key support 200 is accommodated in the first limiting member 311 and can move therein along the Z direction. When the keycap 100 is not pressed, the first limiting member 211 of the key support 200 abuts against the first limiting member limiting surface 311A ​​of the first limiting member 311. When the key mark of the keycap 100 corresponding to the first limiting member 211 is pressed, the first limiting member 211 of the key support 200 can move downward along the first limiting member 311 until it abuts against the second limiting member limiting surface 311B of the first limiting member 311, thereby achieving downward pressure limiting. The other first limiting mating part 311 and the two second limiting mating parts are arranged in the same way, respectively accommodating and guiding the corresponding first limiting part 211 and second limiting part 212. Through this structural design, each limiting protrusion corresponding to the four-way button mark can move independently in its respective groove along the Z direction, realizing the independence and controllability of the four-way pressing operation.

[0033] It should be understood that the limiting surface 311A ​​of the first limiting mating part and the limiting surface 311B of the second limiting mating part can be a plane, an arc-shaped surface, or any other curved surface that can achieve effective limiting. In addition, the surface types of the two can be selected to be the same or different according to specific working conditions and functional requirements.

[0034] In this embodiment, as Figures 1 to 3 As shown, the first limiting member 211 and the second limiting member 212 are positioned on different sides of the center of the key support 200 along the length direction of the keycap 100. Specifically, in this embodiment, the key support 200 has a first key support edge (not shown) in the negative X direction and a second key support edge (not shown) in the positive X direction. Figure 1As shown, the first limiting member 211 and the second limiting member 212 located on the first bracket side 210 are respectively disposed at opposite ends of the first bracket side 210, and are symmetrically arranged along the length of the keycap 100 with respect to the center of the key bracket 200. The line connecting the center of the first limiting member 211 and the center of the second limiting member 212 on the first bracket side 210 is parallel to the length of the keycap 100, and the center distance between the first limiting member 211 and the second limiting member 212 along the length of the keycap 100 is L2; ​​the distance between the first limiting member 211 and the edge of the first key bracket of the key bracket 200 along the length of the keycap 100 is L1; and the distance between the second limiting member 212 and the edge of the second key bracket of the key bracket 200 along the length of the keycap 100 is L3. The first limiting member 211 and the second limiting member 212 on the second bracket side 220 are arranged in a similar manner. This arrangement is as follows: Figure 2 and Figure 3 As shown, when the keycap 100 is pressed under force F1, the keycap 100 will rotate around axis Y2. Correspondingly, when the keycap 100 is pressed under force F2, the keycap 100 will rotate around axis Y1, thus realizing the dual-axis rotation scheme of the four-way switch key device. It should be understood that although in this embodiment, the first limiting member 211 and the second limiting member 212 located on the same side of the bracket are symmetrically arranged with respect to the center of the key support 200, in other embodiments not shown in this utility model, the first limiting member 211 and the second limiting member 212 on the same side of the bracket can also be arranged asymmetrically with respect to the center of the key support 200 as needed. That is, L1 may not be equal to L3.

[0035] Compared to the single-axis structure in existing technologies, this invention utilizes a dual-axis mechanism along the length of the keycap 100. When the key is pressed, the axis farther from the press point serves as the rotation axis, resulting in a longer effective pressing arm and a shorter lifting arm. This makes the pressing stroke greater than the diagonal lifting distance opposite the press point, reducing the overall panel lifting amplitude by more than 50% compared to existing technologies. This design effectively controls the diagonal lifting amount with a smaller pressing stroke, improving the flatness of the key during operation and optimizing the user's sensory experience and product texture. Furthermore, the reduction in planar lifting helps avoid common product quality issues such as noticeable black edges on the keys, light leakage, and excessive structural wobbling, improving the overall reliability and aesthetics of the four-way switch key device.

[0036] The four-way switch button device 10 disclosed in this utility model is not limited to vehicle steering wheels, but can also be applied to smart home control systems (such as smart panels, remote controls, home appliance control interfaces, etc.), consumer electronic devices (such as game controllers, multimedia controllers, portable speakers), and other types of switch operation interfaces that require direction selection or function switching.

[0037] Furthermore, it should be noted that although in the embodiments shown in this utility model, the first limiting member and the second limiting member are respectively in the form of limiting protrusions, and the first limiting mating member and the second limiting mating member are respectively in the form of limiting grooves, it should be understood that the first limiting member and the second limiting member can also be in the form of limiting grooves, and the first limiting mating member and the second limiting mating member can be respectively in the form of limiting protrusions, as long as the engagement of the first limiting member and the first limiting mating member is ensured.

[0038] In one embodiment, such as Figure 2 As shown, the guide frame 300 includes a first limiting part 301 and a second limiting part 302 disposed opposite to each other. The line connecting the center of the first limiting part 301 and the center of the second limiting part 302 is parallel to the length direction of the keycap 100. When the keycap 100 is pressed, the first limiting part 301 and the second limiting part 302 can limit the displacement of the keycap 100 in the pressing direction, thereby forming a virtual rotation axis X, around which the keycap 100 can rotate. Figure 1 and Figure 2 As shown, the three-axis structure proposed in this utility model includes two axes Y1 and Y2 arranged along the length of the keycap 100, and an axis X perpendicular to the axes Y1 and Y2. Optionally, the keycap 100 is also provided with a first stop portion 101 and a second stop portion 102. When the keycap 100 is pressed, the first limiting portion 301 abuts against the first stop portion 101, and the second limiting portion 302 abuts against the second stop portion 102, thereby cooperating to guide the keycap 100 to rotate around the axis X.

[0039] like Figure 3 As shown, the four-way switch button device 10 also includes a reset elastic element 500 and a circuit board 400. The reset elastic element 500 is disposed between the circuit board 400 and the guide frame 300. When the keycap 100 is not pressed, the reset elastic element 500 is in a natural or pre-compressed state. Specifically, as shown... Figure 3As shown, the four-way switch button device 10 also includes four guide rods 600, and the guide frame 300 is correspondingly provided with guide posts 330. Each guide post 330 has a through hole extending along the Z direction for movably accommodating the guide post 330. The guide posts 330 are positioned to correspond one-to-one with the button markings of the four-way switch button device 10 in the Z direction. A reset elastic element 500 is disposed between the guide rods 600 and the circuit board 400. This arrangement ensures that when a button marking on the keycap 100 is pressed, the corresponding keycap moves downward, pushing the guide rod 600 downward along the guide post 330. The force is then transmitted to the circuit board 400 via the reset elastic element 500, triggering a corresponding signal. When the pressing operation ends, the reset elastic element 500 releases its elastic restoring force, pushing the guide rod 600 and the keycap 100 back to their original positions, causing the first limiting member 211 on the button bracket 200 to re-abut against the first limiting mating member limiting surface 311A ​​of the first limiting mating member 311. It should be understood that although the reset elastic element 500 is an arc-shaped spring in this embodiment, this is not a limitation on the scope of protection of this utility model. In other embodiments not shown in this utility model, the reset elastic element 500 may also be a helical spring, disc spring, rubber elastomer, or any other suitable elastic element that can provide reliable restoring force, depending on the actual application requirements.

[0040] As described above, the center distance between the first limiting member 211 and the second limiting member 212 along the length of the keycap 100 is L2; ​​the distance between the first limiting member 211 and the edge of the first key support of the key bracket 200 along the length of the keycap 100 is L1; the distance between the second limiting member 212 and the edge of the second key support of the key bracket 200 along the length of the keycap 100 is L3. That is, the distance between axis Y1 and axis Y2 is L2, the distance between axis Y1 and the edge of the first key support of the key bracket 200 is L1, and the distance between axis Y2 and the edge of the second key support of the key bracket 200 is L2. Figure 3 As shown, in this embodiment, L2 > L1, and L1 = L3. When the keycap 100 is pressed under the force F1, the keycap 100 will rotate around the axis Y2. At this time, the length of the pressing arm is L1 + L2, and the length of the lifting arm is L3. The ratio between the pressing distance on the left and the lifting distance on the right is (L1 + L2) / L3. When the keycap 100 is pressed under the force F2, the keycap 100 will rotate around the axis Y1. At this time, the length of the pressing arm is L3 + L2, and the length of the lifting arm is L1. The ratio between the pressing distance on the right and the lifting distance on the left is (L3 + L2) / L1.

[0041] Optionally, the ratio of L1, L2, and L3 can be configured as 13:18:13. It should be understood that the ratio between L1, L2, and L3 can be adjusted according to actual structural requirements. Under the premise of ensuring mechanical reliability, by changing the distance ratio, flexible control can be achieved over the relationship between the amount of button press and the amount of plane lift, thereby effectively regulating the degree of plane lift during the pressing process.

[0042] In one embodiment, the guide frame 300 is provided with a light-transmitting post 340 having a through hole, and the keycap 100 is provided with a light-transmitting portion 130 in the area corresponding to the light-transmitting post 340. It should be noted that "corresponding" here means that the two are arranged approximately opposite each other in the Z direction. Specifically, as... Figure 1 and Figure 2 As shown, in the installed state, the area on the circuit board 400 corresponding to the light-transmitting column 340 is provided with a light-emitting area (e.g., an LED light source), so that the light emitted by the circuit board 400 can pass through the through hole of the light-transmitting column 340 and through the light-transmitting part 130 of the keycap 100, so that the user can clearly identify the markings on the key in a low-light environment, improving the convenience of operation and visual experience.

[0043] Optionally, the button holder 200 is provided with a third limiting portion 231 located at the edge of the first button holder and a fourth limiting portion 232 located at the edge of the second button holder. The guide frame 300 is provided with a third limiting engagement portion 331 for accommodating the third limiting portion 231 and a fourth limiting engagement portion 332 for accommodating the fourth limiting portion 232. Both the third limiting portion 231 and the fourth limiting portion 232 are designed as circular protrusions extending along the X direction, and the line connecting their centers is parallel to the X direction. In the installed state, the third limiting portion 231 is accommodated within the third limiting engagement portion 331, and the fourth limiting portion 232 is accommodated within the fourth limiting engagement portion 332. This arrangement allows the button holder 200 to move up and down along the Z direction, but its movement in the X and Y directions is restricted, thereby further ensuring the accuracy and stability of the button device's movement when pressed, and avoiding wobbling or jamming.

[0044] Optionally, the keycap 100 is also provided with a snap-fit ​​connector (not shown) that can be detachably connected to the guide frame 300. This configuration ensures that the keycap 100 is reliably mounted on the guide frame 300, restricting the keycap 100 from moving away from the guide frame 300 in the Z direction to prevent accidental detachment, while also ensuring structural stability and the integrity and operational reliability of the keys during use.

[0045] In a second aspect of this invention, a vehicle is provided. The vehicle includes the aforementioned four-way switch button device.

[0046] Although the present invention has been described in conjunction with embodiments, those skilled in the art will understand that the above description and drawings are exemplary and not restrictive, and the present invention is not limited to the disclosed embodiments. Various modifications and variations are possible without departing from the spirit of the present invention.
