For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] As Figures 1 to 3 shown, the embodiment of the first aspect of the present application proposes a vehicle-mounted control device 10. The vehicle-mounted control device 10 comprises a control assembly 100, a pressing piece 210 and a light guide assembly 500. The control assembly 100 comprises a light emitting element 140. The pressing piece 210 is provided with a light transmission part 215. The light guide assembly 500 is arranged between the light emitting element 140 and the pressing piece 210, the light guide assembly 500 is arranged opposite to the light transmission part 215, and the light emitting element 140 provides visible light to the light transmission part 215 through the light guide assembly 500. Illustratively, the control assembly 100 can further comprise a circuit board 110 and a trigger element 120 arranged on the circuit board 110. The light emitting element 140 can be arranged on the circuit board 110. Illustratively, the pressing piece 210 is used to provide pressure to the trigger element 140.

[0040] The vehicle control device 10 can realize one-key control of various functions in the vehicle. For example, the vehicle control device 10 can realize one-key control of a vehicle multimedia system such as music playing, radio switching, video playing, etc., a vehicle environment control system such as air conditioner temperature adjustment, ventilation mode switching, seat heating and ventilation, etc., and a vehicle safety system such as vehicle door lock control, vehicle window lifting, etc.

[0041] The control assembly 100 comprises a circuit board 110, a trigger element 120 and a light emitting element 140, and the pressing member 210 can provide pressing force to the trigger element 120. Under the action of the pressing force, the trigger element 120 itself can generate a state change, thereby transmitting an electrical signal to the circuit board 110. Optionally, the trigger element 120 can be a micro switch, a pressure sensor, a reed, conductive rubber or other types of pressure sensing elements. The trigger element 120 becomes a triggered state after being subjected to the pressing force, and becomes a non-triggered state when not subjected to the pressing force.

[0042] The circuit board 110 is used to receive and process the electrical signal transmitted by the trigger element 120, and convert the electrical signal into a control signal, thereby realizing control of the vehicle function.

[0043] When the trigger element 120 is triggered, the light emitting element 140 is controlled by the circuit board 110 to emit light at the same time. The light emitting element 140 can be, for example, an LED (Light Emitting Diode) chip, which has the characteristics of energy saving, high efficiency, long service life and small size, and does not consume too much power and space of the vehicle control device 10, thereby improving the service life of the vehicle control device 10 and reducing the volume and size.

[0044] The light-transmitting part 215 of the pressing member 210 can transmit the light emitted by the light emitting element 140. The light-transmitting part 215 can be, for example, an identification pattern representing the control function signal of the vehicle control device 10, or can be, for example, an identification pattern representing the trademark information of the manufacturer, which is not limited in the present application. In this way, when the vehicle control device 10 is triggered to control the vehicle function, in the first aspect, the vehicle control device 10 can actively emit light under the action of the light emitting element 140, thereby improving the visibility and aesthetics of the vehicle control device 10 and making the vehicle control device 10 more sophisticated. In the second aspect, the light emitting element 140 can play the role of light indication, prompting the operator of the current operating state of the vehicle control device 10, thereby improving the convenience of the operator.

[0045] The light guide assembly 500 is arranged between the light emitting element 140 and the pressing member 210, and the light guide assembly 500 can transmit the light of the light emitting element 140 to the light-transmitting part 215 after light guide processing, thereby ensuring that the light can be transmitted according to the predetermined path.

[0046] The vehicle-mounted control device 10 of the present application is provided with a light guide assembly 500 between the light emitting element 140 and the pressing member 210. The light guide assembly 500 can play a role in converging light rays and uniformizing light rays, reducing light loss of the light emitting element 140 and improving uniformity of outgoing light, thereby being conducive to improving uniformity and intensity of luminance of the light-transmitting portion 215, and further being conducive to improving user experience of the personnel.

[0047] In some embodiments, as shown in Figure 3 and Figure 4 The light guide assembly 500 includes a light guide body 510 and a diffusion sheet 520. The light guide body 510 is arranged between the light emitting element 140 and the diffusion sheet 520. The light guide body 510 is used to converge light rays of the light emitting element 140, and the diffusion sheet 520 is used to diverge light rays of the light emitting element 140.

[0048] In the present embodiment, the light guide assembly 500 includes the light guide body 510 and the diffusion sheet 520. Since the light emitting element 140 is a point light source, the light guide body 510 can play a role in converging outgoing light rays of the light emitting element 140, thereby reducing light loss. After the diffusion sheet 520 receives the converging light rays of the light guide body 510, the diffusion sheet 520 diverges the light rays, so that the point light source is uniformized into a surface light source. In this way, on the one hand, light loss of the light emitting element 140 can be reduced and uniformity of outgoing light can be improved, thereby being conducive to improving uniformity and intensity of luminance of the light-transmitting portion 215, and on the other hand, it is also conducive to reducing power consumption of the vehicle-mounted control device 10.

[0049] Optionally, the converging effect of the light rays of the light emitting element 140 can be achieved by flexibly designing the shape of the light-incoming surface of the light guide body 510, the shape of the light-outgoing surface of the light guide body 510, the refractive index of the light guide body 510, the thickness of the light guide body 510, and the like. Similarly, the uniformizing effect of the converging light rays of the light guide body 510 can be achieved by flexibly designing the divergence angle of the diffusion sheet 520, the haze of the diffusion sheet 520, the thickness of the diffusion sheet 520, and the like.

[0050] In some embodiments, as shown in Figure 3 The light emitting element 140 is a plurality of light emitting elements 140 and is arranged around the trigger element 120. The orthographic projection of the light guide body 510 on the circuit board 110 covers the plurality of light emitting elements 140. In this way, on the one hand, uniformity of light source distribution and intensity of outgoing light can be improved, and on the other hand, the light converging effect of the light guide body 510 on the plurality of light emitting elements 140 can be improved, and light loss can be further reduced. In this way, it is conducive to further improving uniformity and intensity of luminance of the light-transmitting portion 215, and further conducive to further improving user experience of the personnel.

[0051] Optionally, the trigger element 120 is arranged at the middle region of the circuit board 110, and the number of the light emitting elements 140 is two and arranged at opposite sides of the trigger element 120. In this way, the number of the light emitting elements 140 can be reduced while improving the uniformity and intensity of the brightness of the light transmission part 215, thereby also being conducive to reducing the cost of the vehicle control device 10.

[0052] In some embodiments, as shown in Figure 2 , Figure 5 The vehicle control device 10 further comprises a transmission element 220 connected with the pressing element 210, the transmission element 220 is provided with a first light transmission opening 226, the light guide body 510 is embedded in the first light transmission opening 226, the diffusion sheet 520 is arranged on the side surface of the light guide body 510 away from the light emitting element 140, and the pressing element 210 provides the pressing force to the trigger element 120 through the transmission element 220 and the light guide body 510.

[0053] The pressing element 210 and the transmission element 220 can be connected through magnetic attraction, threaded connection, connector connection, adhesion, buckle connection and the like, and the transmission element 220 can transmit the pressing force of the pressing element 210 to the trigger element 120. As shown in Figure 2 The pressing element 210 is provided with a first magnetic element 214, the transmission element 220 is provided with a second magnetic element 224, and the pressing element 210 and the transmission element 220 are magnetically connected through the first magnetic element 214 and the second magnetic element 224, thereby improving the convenience of the connection between the two.

[0054] Further, in order to improve the stability of the connection between the two, as shown in Figure 3 and Figure 5 The side surface of the pressing element 210 close to the transmission element 220 is provided with a first matching part 216, and the side surface of the transmission element 220 close to the pressing element 210 is provided with a second matching part 225 matched with the first matching part 216. The first matching part 216 can be a pin column arranged on the surface of the pressing element 210, and the second matching part 225 can be a groove matched with the pin column. Alternatively, the first matching part 216 is a plurality of pin columns and grooves, and the second matching part 225 is a plurality of pin columns and grooves correspondingly.

[0055] In the embodiment, the transmission member 220 is provided with a first light transmission opening 226, and the light guide body 510 is embedded in the first light transmission opening 226, thereby constructing a light propagation channel of the light emitting element 140. The emergent light of the light emitting element 140 is incident into the light guide body 510 through the first light transmission opening 226, the light guide body 510 converges the light and then emits the light into the diffusion sheet 520, and the diffusion sheet 520 disperses the light to homogenize the emergent light. By embedding the light guide body 510 in the first light transmission opening 226 of the transmission member 220, on the one hand, the convenience of installing the light guide body 510 can be improved, and on the other hand, the installation and fixation of the light guide body 510 and the transmission member 220 can be realized. The light guide body 510 is used as a light transmission part in the transmission member 220, thereby being beneficial to improving the integration and structural compactness of the vehicle-mounted control device 10.

[0056] In addition, the light guide body 510 is embedded in the first light transmission opening 226, thereby constructing a pressure transmission path. The pressing force of the pressing member 210 is first transmitted to the transmission member 220, and then the transmission member 220 drives the light guide body 510 to press the trigger element 120. Optionally, a buffer member 600 is arranged between the light guide body 510 and the trigger element 120, which can be a pressing rubber sleeve, thereby being beneficial to improving the pressing feeling.

[0057] In some embodiments, the light guide body 510 and the transmission member 220 are formed as an integrated structure by a two-color injection molding process. The two-color injection molding process refers to a process of forming a plastic product with two different colors or material properties by using an injection molding machine with two injection units to successively inject two different plastic materials in the same mold. In this way, on the one hand, the production efficiency can be improved and the production cost can be reduced. On the other hand, the assembly error can be reduced and the accuracy of light transmission can be ensured. Thirdly, the structural strength and stability between the light guide body 510 and the transmission member 220 can be improved, thereby being beneficial to improving the service life and reliability of the vehicle-mounted control device 10. Fourthly, it is beneficial to further improve the integration and structural compactness of the vehicle-mounted control device 10.

[0058] Optionally, in some embodiments, the light guide 510 has a higher light transmittance than the transmission component 220. That is, the light guide 510 and transmission component 220 can be formed from two materials with different light transmittances using a two-color injection molding process. In this way, the light guide 510 has higher light transmittance, allowing light to pass through; while the transmission component 220 has lower light transmittance, blocking light and preventing leakage or scattering in unintended directions, thus avoiding stray light or shadows. This arrangement enhances contrast, making the optical effect of the light-transmitting part 215 more prominent, thereby further improving the user experience. Furthermore, the light guide 510 and transmission component 220 are formed into a single structure through a two-color injection molding process, while also having a difference in light transmittance, achieving a good combination of structural integration and functional differentiation, thereby further improving the reliability of the vehicle control device 10.

[0059] In some embodiments, the light guide 510 and the diffuser 520 are formed into a single structure using a two-color injection molding process. This configuration has several advantages: First, when the light guide 520 is embedded in the first light-transmitting opening 226, the diffuser 520 is simultaneously and securely installed, thus improving the ease of installation. Second, the transmission of light from the light guide 510 to the diffuser 520 is smoother and more continuous, thereby improving the continuity of light transmission. Third, it also helps to improve the structural strength and stability of the light guide 510 and the diffuser 520.

[0060] Optionally, in some embodiments, the haze of the light guide 510 is less than that of the diffuser 520. That is, the two materials with different haze levels can be formed into a single integrated structure—the light guide 510 and the diffuser 520—using a two-color injection molding process. In this way, the light guide 510 has low haze, allowing light to pass through; while the diffuser 520 has high haze, which disperses and homogenizes the light, thereby improving the uniformity of the light. This arrangement further reduces light loss while improving the uniformity of the emitted light, effectively reducing glare and providing a comfortable visual experience for users.

[0061] In some embodiments, such as Figure 5 As shown, the light guide assembly 500 also includes a light-shielding layer 530, which is located on the side of the diffuser 520 away from the light guide body 510. The light-shielding layer 530 is provided with a second light-transmitting opening 531 opposite to the diffuser 520.

[0062] Since the light rays diffused by the diffusion sheet 520 will be diffused in all directions, in this embodiment, a light shielding layer 530 is further arranged on the light exit side of the diffusion sheet 520, and the diffusion sheet 520 is opposite to the second light transmission opening 531 on the light shielding layer 530. In this way, the light shielding layer 530 can effectively block the propagation of light rays in the unnecessary direction, and only allow the light rays to transmit from the second light transmission opening 531. In this way, the directional output of the light rays can be realized, and the light rays can be ensured to accurately reach the light transmission part 215, thereby reducing the visual interference caused by the scattering of light rays to other areas. In addition, the light shielding layer 530 can also enhance the contrast, so that the backlight of the light transmission part 215 is more obvious, thereby facilitating the further improvement of the use experience of the personnel.

[0063] In some embodiments, as shown in Figure 5 and Figure 6 , the light guide assembly 500 further comprises an adhesive layer 540, and the light shielding layer 530 is adhered to the diffusion sheet 520 through the adhesive layer 540, and the light shielding layer 530 is also adhered to the side surface of the transmission member 220 away from the circuit board 110 through the adhesive layer 540.

[0064] In this embodiment, the adhesive layer 540 has two functions. First, the light shielding layer 530 is connected to the diffusion sheet 520 through the adhesive layer 540, that is, the area of the diffusion sheet 520 is larger than the opening area of the second light transmission opening 531, so that the diffusion sheet 520 also has a part for adhering to the light shielding layer 530. In this way, the loosening or displacement of the diffusion sheet 520 due to vehicle vibration, bumping and the like can be avoided, thereby facilitating the improvement of the reliability and stability of the working of the diffusion sheet 520. Second, the light shielding layer 530 is also adhered to the side surface of the transmission member 220 away from the circuit board 110 through the adhesive layer 540. In this way, on the one hand, the light shielding effect of the light shielding layer 530 can be improved, and on the other hand, the integration and structural stability between the light guide assembly 500 and the transmission member 220 can be enhanced, thereby facilitating the improvement of the strength and stability of the light guide assembly 500. It can be understood that the adhesive layer 540 is also provided with a light transmission opening.

[0065] In some embodiments, as shown in Figure 2 and Figure 7 , the vehicle-mounted control device 10 further comprises a housing 400 and a power supply assembly 300, the housing 400 is provided with a receiving groove 401, the circuit board 110 is arranged in the receiving groove 401 to form a power supply cavity 4011 with the housing 400, the trigger element 120 and the light-emitting element 140 are located on the side of the circuit board 110 away from the power supply cavity 4011, and the pressing member 210 is movably installed in the slot of the receiving groove 401. The power supply assembly 300 is arranged in the power supply cavity 4011 and electrically connected with the control assembly 100.

[0066] The shell 400 is a housing of the vehicle-mounted control device 10, used for accommodating the control assembly 100 and the power supply assembly 300. Specifically, the shell 400 includes a base 410 and a frame 420, which enclose a receiving groove 401.
