[0032] Please refer to Figures 1 to 5 The utility model provides a kind of vehicle navigation combination switch, comprising:

[0033] The circuit board 100 is provided with an encoder 110 and a light source 120, and the light source 120 is located at the periphery of the encoder 110.

[0034] The knob 200 is sleeved on the encoder 110 and covers the light source 120, and the knob 200 is provided with a first mounting cavity 210.

[0035] The light guide ring 300 is arranged in the first mounting cavity 210, and the light guide ring 300 is configured with a second mounting cavity 310, and the end face of the second mounting cavity 310 is flush with the end face of the first mounting cavity 210.

[0036] The pressing key 400 is inserted into one end of the encoder 110 and covers the open end of the second mounting cavity 310.

[0037] The circuit board 100 is the control core of the vehicle navigation combination switch, carries the signal processing and light source driving function, wherein the circuit board 100 can be circular design. In the embodiment, the middle part of the circuit board 100 is provided with a hollow encoder 110, which is the core sensing component of the knob 200 operation, used for identifying the rotation angle and direction of the knob 200, and converting mechanical movement into electrical signal transmission to the vehicle navigation instrument.

[0038] The light source 120 provides the illumination light source, which can adopt low-power LED lamp beads, and a plurality of LED lamp beads are arranged at the periphery of the encoder 110, and the light direction thereof is towards the knob 200, thereby providing the basic light source for the light emission of the light guide ring 300. The light source 120 can also adopt a low-power LED light source, such as a ring-shaped LED light belt, which is arranged in a ring shape at the periphery of the encoder 110. Of course, the type of the light source 120 is only exemplary, and the specific type can be determined according to actual needs, and the utility model does not limit it here.

[0039] The knob 200 is sleeved outside the encoder 110 to form an outer operation shell, which can be rotated by the user to contact, and covers the light source 120 above, thereby playing a role of protecting the light source 120, light guide and operation carrier. The material of the knob 200 can be engineering plastic. When the user rotates the knob 200, the encoder 110 is driven to move synchronously, and the adjustment operation is completed; the structure design of covering the light source 120 ensures that the light of the light source 120 is constrained inside, reduces the light leakage interference, and improves the intensity of the light ring.

[0040] Please refer to Figure 2 and Figure 3 and Figure 4, by setting the first mounting cavity 210 in the knob 200, the light guide ring 300 is built in the knob 200, the light guide ring 300 is provided with the second mounting cavity 310 containing the pressing key 400, one end of the pressing key 400 is connected with the encoder 110 to establish electrical connection, the other end of the pressing key 400 covers the open end of the second mounting cavity 310. The end faces of the first mounting cavity 210 and the second mounting cavity 310 are substantially flush, and the end face of the pressing key 400 is substantially flush with the end face of the second mounting cavity 310. When the light source emitted by the light source 120 irradiates the end face of the light guide ring 300, a uniform and clear annular light ring is formed, and at this time, the annular light ring is located between the knob 200 and the pressing key 400, and the operation area of the knob 200 and the pressing key 400 can be directly displayed, which is convenient for user operation. The material of the light guide ring 300 can be polycarbonate (PC) or polymethyl methacrylate (PMMA), as long as it has excellent optical performance and high transparency, and the light of the light source 120 can be transmitted outside to be captured by the user, and the utility model does not make limitation here.

[0041] The utility model discloses a circuit board 100 is provided with the encoder 110, the periphery of encoder 110 is provided with the light source 120 that can emit light, and the knob 200 of the outside sleeve joint of encoder 110 can be quickly operated, the knob 200 is provided with the first mounting cavity 210 containing the light guide ring 300, the light guide ring 300 sets up the second mounting cavity 310, and one end of the pressing key 400 is inserted with the encoder 110, and the other end covers the open end of the second mounting cavity 310, and at this time, the end faces of the first mounting cavity 210, the second mounting cavity 310 and the pressing key 400 are substantially flush, when the circuit board 100 is electrified, the light source 120 can be driven to emit light towards the light guide ring 300, and finally, a uniform annular light ring is formed on the end face of the second mounting cavity 310 of the light guide ring 300, the annular light ring is located between the knob 200 and the pressing key 400, and the knob 200 and the pressing key 400 can be illuminated and positioned at the same time, which is convenient for user operation, and improves the operation accuracy and operation comfort of vehicle navigation.

[0042] Please refer to Figure 4 The second mounting cavity 310 includes the step 320 containing the pressing key 400, and the first through hole 220 is arranged in the middle of the step 320, and the pressing key 400 is inserted with the encoder 110 through the first through hole 220.

[0043] The main role of the step 320 is to support and limit the pressing key 400, when the user presses the pressing key 400, the pressing key 400 is axially displaced along the first through hole 220 under the driving of the pressure to trigger the encoder 110 signal. Through the step 320, the axial displacement of the pressing key 400 can be limited to exceed, improve the control accuracy of the press switch, improve the user operation comfort, and the step 320 can provide certain support to the pressing key 400, avoid the axial displacement of the pressing key 400 under the action of gravity.

[0044] Please refer to Figure 3 and Figure 4 , the first installation cavity 210 is provided with a plurality of first positioning ribs 240, and one end of the light guide ring 300 towards the encoder 110 is provided with a first positioning groove matched with the first positioning rib 240.

[0045] Among them, the number of first positioning ribs 240 can be 4, which are circumferentially distributed in the first installation cavity 210. When assembling the vehicle navigation combination switch of the utility model, the first positioning groove of the light guide ring 300 is first connected with the first positioning rib 240, realizing the installation of the rotary knob 200 and the light guide ring 300.

[0046] Please refer to Figure 3 , in the embodiment, the bottom wall of the first installation cavity 210 is further provided with a plurality of second light transmission parts 330, for example, four second light transmission parts 330, and the adjacent two second light transmission parts 330 are connected through the first positioning rib 240. By setting the second light transmission part 330, the light emitted by the light source 120 towards the rotary knob 200 can be avoided to be blocked by the rotary knob 200, the light can be irradiated to the light guide ring 300 from the second light transmission part 330, and finally form a ring-shaped light ring on the end face of the light guide ring 300.

[0047] Please refer to Figure 3 and Figure 4 , in another embodiment, the first installation cavity 210 is provided with a plurality of second positioning grooves 250, and one end of the light guide ring 300 towards the encoder 110 is provided with a second positioning rib 350 matched with the second positioning groove 250.

[0048] Among them, the number of second positioning grooves 250 of the first installation cavity 210 can be 4, and the second positioning groove 250 is located on the side wall of the second light transmission part 330, and the second positioning rib 350 is correspondingly provided with 4, when the rotary knob 200 and the light guide ring 300 are combined, the second positioning rib 350 can be connected with the second positioning groove 250, further improving the connection stability of the rotary knob 200 and the light guide ring 300.

[0049] Please continue to refer to Figure 3 and Figure 4The inner wall of the first mounting cavity 210 is provided with multiple fastening platforms 260, and the light guide ring 300 is provided with multiple hooks 360 that cooperate with the fastening platforms 260. The fastening platforms 260 and the hooks 360 cooperate to position the light guide ring 300 and the knob 200.

[0050] The number of mounting platforms 260 can be three. The step 320 of the light guide ring 300 facing the first mounting cavity 210 has a number of identical hooks 360. When assembling the knob 200 and the light guide ring 300, the hooks 360 can engage with the mounting platforms 260, further improving the connection strength between the knob 200 and the light guide ring 300, ensuring that the light guide ring 300 can rotate synchronously with the knob 200, and preventing the light guide ring 300 from loosening and causing the knob 200 to be unable to rotate, thus affecting operation.

[0051] Please refer to Figure 3 and Figure 4 A boss 270 is provided within the first mounting cavity 210, and multiple guide grooves 271 are provided axially on the end face of the boss 270. The hook 360 passes through the guide grooves 271 and engages with the boss 260. The end face of the boss 270 is hollow, and the three guide grooves 271 can guide the hook 360, facilitating positioning during assembly and improving assembly efficiency. At the same time, the guide grooves 271 can also limit the circumferential displacement of the hook 360, preventing the light guide ring 300 from rotating and loosening, thus improving connection stability.

[0052] Please refer to Figure 3 and Figure 4 Multiple light sources 120 are arranged around the encoder 110; the light guide ring 300 has multiple first light-transmitting parts 230 corresponding to the light sources 120. In this embodiment, there are eight light sources 120 arranged along the circumference of the encoder 110. When the eight light sources 120 simultaneously emit light towards the light guide ring 300, some of the light passes through the second light-transmitting part 330 and the first light-transmitting part 230 in sequence and illuminates the end face of the light guide ring 300, forming a ring-shaped light on the outer end face of the light guide ring 300. By emitting different colored light from the eight light sources 120, a seven-color ambient ring-shaped light is formed, enhancing the visual appearance of the vehicle navigation combination switch and improving the user experience.

[0053] In this embodiment, four first light-transmitting portions 230 are provided. Each first light-transmitting portion 230 penetrates the step 320 axially and extends to the sidewall of the second mounting cavity 310. Light from the lamp source 120 is directionally transmitted through the second light-transmitting portion 330 to the light guide ring 300, and then enters the corresponding first light-transmitting portion 230. The first light-transmitting portion 230 homogenizes the light, scattering it to make the light distribution within the light guide ring 300 more uniform. Subsequently, the light further propagates and diffuses within the light guide ring 300. Through the synergistic effect of multiple first light-transmitting portions 230, secondary homogenization of the light is achieved, ultimately forming a light ring with uniform brightness.

[0054] Please refer to Figure 2 The end of the light guide ring 300 facing the light source 120 is also provided with a micro-tooth structure 370. On the one hand, the uneven surface of the micro-tooth structure 370 changes the direction of light propagation, dispersing the originally concentrated direct light into scattered light at multiple angles, avoiding the formation of local strong light or shadow within the light guide ring 300. On the other hand, the reflection and refraction path of light between the micro-tooths is extended, increasing the contact opportunity between the light and the material of the light guide ring 300, allowing the light to penetrate more evenly into the overall structure of the light guide ring 300. Thus, the micro-tooth structure 370 can homogenize the light, ensuring consistent brightness on the end face of the light guide ring 300, avoiding problems such as localized bright and glaring light or localized over-blurring, and making the knob 200 and the button 400 clearer.

[0055] Please refer to Figure 5 Figure 4 Figure 2 The end of the press button 400 covering the open end of the light guide ring 300 is concave from the outside in. The tip of a human finger (finger pad) naturally has a slightly curved, convex shape. The concave curvature of the press button 400 complements the curvature of the finger pad, conforming to ergonomics and improving pressing comfort. Furthermore, the inclined inner wall of the concave structure forms a "guide slope," directing the user's natural force towards the axis of the press button 400, reducing lateral force and concentrating the axial force on the press button 400, thus preventing pressing stutters or signal delays caused by force deviation.

[0056] Another aspect of this utility model proposes a vehicle navigation device, including a faceplate and a vehicle navigation combination switch as described above. The vehicle navigation combination switch is disposed on the faceplate, and the faceplate is detachably connected to a main control unit.

[0058] The above are only some or preferred embodiments of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model.
