[0002] With the development of intelligent driving, cars have gradually evolved into the third living space of human beings. The demand for ambient lighting on the surface of car interiors has gradually increased, and the effects of ambient lighting on the surface of car interior components have also been iteratively developed. For example, new energy vehicles have integrated voice assistants to interact with a variety of ambient light colors, or to interact with ambient lighting through music, but the ambient lighting effects on the surface of car interior components are still relatively simple and cannot interact with the driver in terms of light or sound.

[0003] In the prior art, although ambient lights are also added to car steering wheels, the lighting effects of existing steering wheel ambient lights are single, and it is difficult for the ambient lights to be perfectly integrated into the steering wheel after installation, resulting in a sense of separation between the ambient lights and the steering wheel.

[0048] It should be noted that various aspects of the embodiments within the scope of the appended claims are described below. It should be apparent that the aspects described herein can be embodied in a wide variety of forms, and any specific structure and / or function described herein is merely illustrative. Based on the present application, it should be understood by those skilled in the art that an aspect described herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number and aspect described herein can be used to implement the device and / or practice the method.

[0049] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application.

[0050] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0051] In the prior art, although atmosphere lights are added to the steering wheels of cars to improve their functionality and aesthetics, the lighting effects of the atmosphere lights on the steering wheels of cars are single, and the atmosphere lights usually only emit light in a single mode / effect at a fixed position on the steering wheel of the car, such as emitting light in a single mode / effect in a part of the area above the steering wheel handle 11 facing the driver. In addition, the turning on and off or the switching of the light colors of the existing car steering wheel atmosphere lights are all adjusted by the embedded software or physical case of the car computer, and cannot interact with the driver and passengers in real time. Therefore, the existing car steering wheel atmosphere lights can no longer meet the requirements of iterative development of the surface of car interior lighting.

[0052] In addition, when installing the existing steering wheel ambient light, it is necessary to cut the outer leather cover of the steering wheel to allow the light to be emitted outward, which undoubtedly creates a sense of fragmentation on the steering wheel and the ambient light cannot be perfectly integrated into the steering wheel.

[0053] Based on this, this specification embodiment proposes a processing solution: Figure 1 As shown, a steering wheel of the utility model uses a lens 21 and a foam body 112 to form a closed circumferential contour and an accommodating space 211, and then installs a light-emitting component 22 with multiple light-emitting modes / functions in the accommodating space 211, so that a sensing signal is generated when the sensing pad 23 detects a human hand, and the processing unit 25 controls the light-emitting component 22 to realize different light-emitting modes according to the sensing signal, thereby enhancing the lighting effect of the steering wheel atmosphere light; in addition, the light emitted by the light-emitting component 22 is evenly emitted by the lens 21, and the external light-transmitting sheath 24 is used to completely cover the sensing pad 23, the lens 21, and the light-emitting component 22 without blocking the light emitted by the light-emitting component 22 after covering, so that the steering wheel as a whole is more unified, complete, and without fragmentation, and the overall display of the steering wheel atmosphere light is more uniform, which solves the problem of the single effect and the inability to perfectly integrate the automotive steering wheel atmosphere light in the prior art, and also enhances the interactivity between the driver and the steering wheel atmosphere light.

[0054] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0055] like Figures 1 to 3 As shown, an embodiment of the utility model provides a steering wheel, including a steering wheel body 10 and a light emitting unit 20 arranged on a handle 11 of the steering wheel body 10 , the handle 11 including a handle frame 111 and a foam body 112 molded on the periphery of the handle frame 111 .

[0056] The steering wheel body 10 includes a wheel hub, spokes, a handle 11 (rim) and a pad. The wheel hub is located at the center of the steering wheel, used to connect the steering wheel and the steering column, and used to transmit the driver's steering force to the steering system; the spokes are used to connect the wheel hub and the handle 11 components, used to provide structural support and maintain the overall rigidity of the steering wheel; the handle 11 is the outer ring of the steering wheel and is actually held by the driver; the pad is usually located in the central area of ​​the steering wheel, used to cover the wheel hub and protect the driver from being hurt by the hard wheel hub.

[0057] Among them, a light-emitting unit 20 is also arranged on the handle 11. The light-emitting unit 20 is a component used to emit light when the car is ignited or started. The light-emitting unit 20 can have different light-emitting modes / effects, and can also have multiple light-emitting patterns, brightness, intensity, frequency and other functions.

[0058] The light emitting unit 20 may be disposed on the handle ring 11 along an extension direction of the handle ring 11 , where the extension direction of the handle ring 11 is a direction in which the handle ring 11 extends on a plane where the handle ring 11 is located.

[0059] In some of the embodiments, the light emitting unit 20 may be disposed in a partial area in the extending direction of the handle ring 11 , or may be disposed in the entire area in the extending direction of the handle ring 11 .

[0060] The foam body 112 is made of a foam material and may have a certain elasticity so that the driver can hold the steering wheel more comfortably or play a certain buffering role to protect the driver when the driver collides with the handle 11 .

[0061] When the foam body 112 is formed, at least a portion of the periphery of the foam body 112 away from the steering wheel skeleton is provided with a circumferential contour, so that after the steering wheel is formed, the periphery of the longitudinal section of the steering wheel is a circular or nearly circular structure.

[0062] The handle frame 111 may be an aluminum-magnesium bracket.

[0063] Furthermore, the light emitting unit 20 includes a lens 21 , a light emitting element 22 , a sensing pad 23 , an outer light-transmitting sheath 24 and a processing unit 25 . Among them, the lens 21 is fixed on the foam body 112, and its outer surface forms a closed circumferential contour with the first part of the outer surface of the foam body 112, and its inner surface forms a containing space 211 with the second part of the outer surface of the foam body 112; the light-emitting element 22 is arranged in the containing space 211, and its function is configured to be at least one or more of on / off lighting, lighting pattern, frequency, intensity, color and shape of on / off lighting cycle; the sensing pad 23 covers at least part of the closed circumferential contour, and is used to generate a sensing signal when a human hand is detected; the external light-transmitting sheath 24 covers at least part of the closed circumferential contour and is located on the side of the sensing pad 23 away from the closed circumferential contour; the processing unit 25 is respectively communicated with the sensing pad 23 and the light-emitting element 22, and is used to control the light-emitting element 22 to realize the function of the light-emitting element 22 according to the sensing signal generated by the sensing pad 23, and the light emitted by the light-emitting element 22 can penetrate the lens 21 and the external light-transmitting sheath 24 and emit to the outside.

[0064] Among them, the outer surface of the lens 21 described in the utility model refers to the side surface away from the foam body 112 after the lens 21 is fixed on the foam body 112, and the inner surface refers to the side surface facing the foam body 112 after the lens 21 is fixed on the foam body 112.

[0065] The longitudinal section of the lens 21 is generally fan-shaped, so after the lens 21 is fixed on the foam body 112 , the outer surface of the lens 21 cooperates with the outer surface of the foam body 112 to form a closed circumferential contour.

[0066] Specifically, the width of the side of the lens 21 close to the foam body 112 is approximately equal to the width of the side of the foam body 112 close to the lens 21, so that when the lens 21 is fixed to the foam body 112, a good transition can be formed between the lens 21 and the foam body 112 without forming a step.

[0067] Among them, the inner surface where the lens 21 is connected to the foam body 112 protrudes outward to form a protrusion, and the protrusion is arranged along the extension direction of the lens 21. When the lens 21 is fixed to the foam body 112, the protrusion is embedded in the foam body 112 to avoid misalignment between the lens 21 and the foam body 112 when the steering wheel is in use. At the same time, the protrusion can also increase the contact connection area between the lens 21 and the foam body 112 to avoid separation between the lens 21 and the foam body 112.

[0068] The lens 21 is connected to the foam body 112 via the protrusion by bonding, gluing, interference fit, etc.

[0069] In some of the embodiments, the lens 21 may not be provided with protrusions and may be directly connected to the foam body 112 by pasting, gluing, etc.

[0070] The lens 21 is also used to make the light emitted by the light emitting element 22 diffuse evenly along the lens 21 , so that when the light is emitted outward, the outer light-transmitting sheath 24 is displayed more evenly as a whole.

[0071] The lens 21 may be extended into a ring-shaped structure or an arc-shaped structure to cooperate with a part or all of the outer surface of the foam body 112 to form a closed circumferential contour of different sizes.

[0072] Preferably, the lens 21, the ring frame 111 and the foam body 112 are all arranged as an annular structure, so that the lens 21 cooperates with the foam body 112 to form a closed circumferential contour of the annular structure.

[0073] In some of the embodiments, when the handle frame 111 is formed of two opposite arc-shaped structures, the lens 21 may be one or two, so that the lens 21 is disposed on one or two handle frames 111 .

[0074] The lens 21 may be made of transparent materials such as glass and crystal.

[0075] The utility model uses a lens 21 in conjunction with a foam body 112 to form a closed circumferential contour of the steering wheel, which can effectively improve the collimation of the light source of the light-emitting component 22 and improve the uniformity of the steering wheel atmosphere light. Moreover, by using the lens 21 for focusing, the light-emitting component 22 can use a low-power LED, thereby effectively controlling the temperature rise of the steering wheel.

[0076] The light emitting element 22 is fixedly disposed in the accommodation space 211 to realize functions such as on / off lighting, lighting patterns, frequency, intensity, color, and shape of on / off lighting cycles, etc. The light emitting element 22 can realize different functions under the control of the processing unit 25, such as turning the light emitting element 22 on or off under the control of the processing unit 25.

[0077] Specifically, the processing unit 25 can control the turning on and off of the light-emitting component 22, adjust the lighting pattern of the light-emitting component 22, and adjust the light-emitting mode of the light-emitting component 22, such as adjusting the frequency, light intensity, light color, and light shape of the light-emitting component 22.

[0078] The light emitting element 22 includes a full-color LED lamp, so that the light emitting element 22 can achieve the above functions.

[0079] In some of the embodiments, the light emitting member 22 is disposed on a portion or the entire area of ​​the handle frame 111 along the extension direction of the handle frame 111 .

[0080] Preferably, the light emitting member 22 and the handle ring frame 111 are both configured as an annular structure, so that the light emitting member 22 can emit light in a region along the extension direction of the handle ring frame 111 .

[0081] In some of the embodiments, when the handle frame 111 is formed of two opposite arc-shaped structures, the number of the light-emitting element 22 may be one or two, so as to be disposed on one or two handle frames 111 .

[0082] Among them, the sensing pad 23 is connected to the processing unit 25 through a line. When it senses the approach of a human hand, it can generate a sensing signal and send it to the processing unit 25 through the line. After the sensing pad 23 covers the closed circumferential contour, the sensing pad 23 does not completely block or does not block the light emitted by the light-emitting element 22, so that the light can penetrate the lens 21 and the external light-transmitting sheath 24 and emit outward.

[0083] The sensing pad 23 is a long strip structure, and its width can be set according to actual needs.

[0084] In some of the embodiments, when the width of the sensing pad 23 is small, the sensing pad 23 is covered on the closed circumferential contour along the extension direction of the closed circumferential contour. At this time, the sensing area of ​​the sensing pad 23 in the closed circumferential contour is small, but the human hand can still be detected when the human hand holds the steering wheel.

[0085] In some embodiments, when the width of the sensing pad 23 is large, the sensing pad 23 covers at least a portion of the closed circumferential contour along the extension direction of the closed circumferential contour to increase the sensing area of ​​the sensing pad 23 in the closed circumferential contour.

[0086] When the width of the sensing pad 23 is relatively large, the sensing pad 23 only covers a portion of the closed circumferential contour, so as to avoid blocking the light from being emitted outward when the sensing pad 23 completely covers the closed circumferential contour.

[0087] In some of the embodiments, the sensing pad 23 is arranged along the extension direction of the handle ring frame 111, and after covering the closed circumferential contour, the sensing area of ​​the sensing pad 23 is arranged along the extension direction of the handle ring frame 111, so that the driver's hand can be sensed by the sensing pad 23 at any position on the handle ring frame 111.

[0088] For example, after the sensing pad 23 covers the closed circumferential contour along the extension direction of the handle frame 111 , the sensing pad 23 forms an annular structure or an arc structure matching the steering wheel.

[0089] In the present application, the working sensing principle of the sensing pad 23 is the same as that in the prior art, and will not be described in detail here.

[0090] The thickness of the sensing pad 23 may be 0.7 mm, and the detection distance may be 2 mm.

[0091] In the present application, the outer light-transmitting sheath 24 is a light-transmitting element, and after the outer light-transmitting sheath 24 is covered with a closed circumferential contour, light can penetrate the outer light-transmitting sheath 24 .

[0092] The outer light-transmitting sheath 24 is made of light-transmitting material, such as light-transmitting leather.

[0093] Specifically, the outer light-transmitting sheath 24 includes a substrate and a light-transmitting film. The substrate layer and the light-transmitting film layer are stacked, and both the substrate layer and the light-transmitting film layer can be penetrated by light.

[0094] Among them, the thickness of the light-transmitting film is 0.2mm and the transmittance is 20%; the base material is made of PC resin material and has a thickness of 0.6mm; the surface color is black-gray, and the above thickness and transmittance can be adjusted according to actual requirements.

[0095] In some of the embodiments, the outer light-transmitting sheath 24 at least covers the light-emitting area 213 on the lens 21 to prevent the lens 21 from being directly exposed to the outside, which would cause the lens 21 to emit light with too high brightness.

[0096] The outer light-transmitting sheath 24 may only cover the light-emitting area 213 on the lens 21 , and its length is equal to that of the light-emitting area 213 of the lens 21 , and its width is greater than or equal to that of the light-emitting area 213 on the lens 21 .

[0097] In some of the embodiments, the outer light-transmitting sheath 24 may completely cover the closed circumferential contour to shield the lens 21 and the light-emitting element 22 , so that the outer portion of the steering wheel forms an integral whole, thereby improving the aesthetics of the outer periphery of the steering wheel.

[0098] Specifically, the outer light-transmissive sheath 24 may be arranged along the extension direction of the closed circumferential contour, and the outer light-transmissive sheath 24 completely covers the closed circumferential contour in the circumferential direction of the closed circumferential contour.

[0099] The light-transmitting external cover 24 of the utility model overcomes the problem that the existing leather blocks light, resulting in the steering wheel being able to emit light only by cutting off part of the leather (steering wheel external cover) and embedding a light-emitting device, thereby achieving the same light-transmitting effect as a traditional steering wheel when the internal light-emitting part 22 is not lit and the light-emitting part 22 is lit.

[0100] In the present application, the processing unit 25 is a vehicle-mounted control processing unit, which can receive and send data, such as receiving a sensing signal sent by the sensing pad 23, and sending the sensing signal to the light-emitting element 22, so that the light-emitting element 22 can realize the corresponding function.

[0101] Among them, the processing unit 25 controls the light emitting element 22 to emit light according to the sensing signal, which is a prior art and is not the focus of the utility model of this application.

[0102] For example, the processing unit 25 may be an on-vehicle ECU.

[0103] The processing unit 25 may be integrated into the steering wheel and communicated with the vehicle-mounted central control unit.

[0104] In some of the embodiments, the processing unit 25 can control the light emitting element 22 to implement different functions of the light emitting element 22 according to different types of sensing signals sent by the sensing pad 23 .

[0105] In some of the embodiments, the processing unit 25 can obtain an indication signal from the vehicle-mounted central control unit, and control the light-emitting element 22 to implement different functions of the light-emitting element 22 according to the indication signal.

[0106] In some of the embodiments, the processing unit 25 is capable of communicating with an external terminal device, and after obtaining an instruction from the external terminal device, controls the light-emitting element 22 according to the instruction to implement different functions of the light-emitting element 22 .

[0107] Specifically, when the steering wheel is in use, if the sensing pad 23 detects a human hand, the sensing pad 23 sends a sensing signal to the processing unit 25. The processing unit 25 controls the light-emitting component 22 according to the sensing signal to realize the function of the light-emitting component 22, so that the light-emitting component 22 emits light according to the preset function. The light emitted by the light-emitting component 22 can penetrate the lens 21 and the external light-transmitting cover 24 and emit to the outside, so that the driver and passengers have a certain interaction with the steering wheel, and the texture of the steering wheel light is adjusted through the lens 21 and the external light-transmitting cover 24, so that the texture of the steering wheel atmosphere light is more uniform and the glare of the light is avoided.

[0108] like Figure 1 As shown, the shape of the outer surface of the second part of the foam body 112 can be a plane structure 113, or a curved surface structure with a smaller slope.

[0109] Preferably, the second portion of the outer surface of the foam body 112 is set as a plane structure 113, and the plane structure 113 of the foam body 112 cooperates with the inner surface of the lens 21 to form a accommodating space 211 with a fan-shaped cross-section, and the accommodating space 211 is used to install the light-emitting component 22, and by setting the second portion of the outer surface of the foam body 112 as the plane structure 113, the installation of the light-emitting component 22 is facilitated.

[0110] The second portion of the outer surface of the foam body 112 is mainly the outer surface facing the lens 21 .

[0111] like Figure 4As shown, a shading area 212 and a light emitting area 213 naturally formed after the shading area 212 is set are provided on the lens 21, and the light emitted by the light emitting element 22 can penetrate the light emitting area 213 of the lens 21 and the external light-transmitting sheath 24 to be emitted outward.

[0112] The width of the light emitting area 213 may be 5 mm, and the width may be adjusted according to actual requirements.

[0113] A light shielding area 212 may be provided on the outer surface and / or the inner surface of the lens 21 . Since the lens 21 itself is completely light-transmissive, the area not covered by the light shielding area 212 is the light emitting area 213 .

[0114] For example, the light shielding area 212 may be provided on the outer surface, the inner surface, or both the outer surface and the inner surface of the lens 21 .

[0115] Preferably, the shading area 212 is disposed on the outer surface of the lens 21 , so that the inner surface of the lens 21 and the lens 21 itself can gather and refract the light, and can well control the direction in which the light is emitted outward.

[0116] A light shielding material may be coated on the lens 21 to form a light shielding area 212 on the lens 21 .

[0117] Preferably, when the shading area 212 is formed on the outer surface of the lens 21 , a groove can be first carved on the outer surface of the shading area 212 , and then a shading material can be coated in the groove to form the shading area 212 , thereby ensuring the flatness of the outer surface of the lens 21 .

[0118] In some of the embodiments, both sides of the lens 21 may be set as the light shielding area 212 , and the portion between the two light shielding areas 212 is the light emitting area 213 .

[0119] In some of the embodiments, the shape of the shading area 212 can be flexibly adjusted so that the light-emitting area 213 has different shapes, so as to increase the aesthetics and personalized setting of the steering wheel atmosphere light.

[0120] For example, the shape of the light shielding area 212 may be adjusted so that the light extracting area 213 forms a serpentine structure along the extending direction of the steering wheel.

[0121] In the present invention, the light emitting area 213 is not partially or completely blocked by the sensor pad 23 , so the light emitted by the light emitting element 22 can penetrate the light emitting area 213 and the outer light-transmitting sheath 24 and emit outward.

[0122] In some of the embodiments, the sensing pad 23 is arranged on the circumference of the handle ring 11, with one end covering the outer side of the handle ring 11 and close to the upper area, and the other end extending to the inner side of the handle ring 11 after passing through the lower part of the handle ring 11, and is configured to generate a sensing signal when a human hand touches the outer side of the handle ring 11.

[0123] Specifically, one end of the sensing pad 23 is wrapped around the outer surface of the lens 21 and close to the light emitting area 213 of the lens 21, and the other end bypasses the lens 21 and the foam body 112 and extends to the first part of the outer surface of the foam body 112, so that the sensing pad 23 can wrap at least part of the lens 21 and part of the foam body 112.

[0124] Preferably, when one end of the sensing pad 23 is wrapped around the outer side of the outer surface of the lens 21 and the other end bypasses the lens 21 and the foam body 112 and extends to the first part of the outer surface of the foam body 112, both ends of the sensing pad 23 do not invade the light emitting area 213, thereby preventing the sensing pad 23 from blocking the light emitted by the light emitting element 22.

[0125] The sensing pad 23 is used to sense a human hand, and the sensing pad 23 is relatively wide, so as to increase the sensing area for the human hand without affecting the light emitted by the light emitting element 22 .

[0126] The utility model makes one end side of the sensing pad 23 cover the outer side of the handle ring 11, and the other end side wraps around the lower part of the handle ring 11 and extends to the inside of the handle ring 11, so that most areas of the steering wheel handle ring 11 can sense human hands, thereby increasing the sensing area of ​​the steering wheel while not affecting the light emitted from the light emitting element 22.

[0127] In some of the embodiments, the sensing pad 23 may only cover the lens 21 area in the closed circumferential contour or the foam body 112 area in the closed circumferential contour. In this case, when a person's hand is tightly gripping the steering wheel, the human hand can still be sensed.

[0128] In some of the embodiments, Figure 5 As shown, a focusing structure 214 is provided on the inner surface of the lens 21 corresponding to the light emitting area 213. The focusing structure 214 is used to focus the light emitted by the light emitting component 22 to the light emitting area 213. Its specific shape can be flexibly set according to the shape and size of the light emitting component 22. For example, it can be set to a concave structure.

[0129] Preferably, the focusing structure 214 is extended from the inner surface of the lens 21 to the outer surface of the second part of the foam body 112, and includes two oppositely arranged conical structures 2141 and a refractive arc structure 2142 located between the two conical structures 2141. The refractive arc structure 2142 is arranged corresponding to the light-emitting component 22. The focusing structure 214 is used to focus the light of the light-emitting component 22 to the light-emitting area 213 and emit it outward.

[0130] The focusing structure 214 is integrally provided with the inner surface of the lens 21 , for example, can be integrally injection molded or integrally cast.

[0131] The light emitting element 22 , the light focusing structure 214 , and the light emitting area 213 are substantially located on the same plane, so that the light focusing structure 214 can focus the light emitted by the light emitting element 22 toward the light emitting area 213 .

[0132] For example, when the steering wheel is laid flat, the light-collecting structure 214 and the light-emitting element 22 are arranged correspondingly up and down, and the light-emitting area 213 is located directly above the light-collecting structure 214 and the light-emitting element 22 .

[0133] Furthermore, if Figure 6 As shown, the refractive arc structure 2142 is a convex structure, and the opposite sides of the conical structure 2141 are also configured as convex arc structures to better gather the light emitted by the light emitting element 22 so that the light can be refracted toward the light emitting area 213 .

[0134] Furthermore, the two opposite sides of the two conical structures 2141 are both set as inclined surfaces, and their slope can be flexibly set according to the position and size of the light-emitting component 22. Their function is to refract the light toward the light-emitting area 213 after obtaining the light emitted by the light-emitting component 22.

[0135] Specifically, when the light emitted by the light emitting component 22 propagates to the refractive arc structure 2142, the refractive arc structure 2142 can refract the light toward the light emitting area 213. When the light emitted by the light emitting component 22 propagates to the convex arc structure of the conical structure 2141, the convex arc structure of the conical structure 2141 refracts the light onto the inclined surface of the conical structure 2141. Finally, the inclined surface of the conical structure 2141 refracts the light toward the light emitting area 213.

[0136] Furthermore, the width of the refractive arc structure 2142 is greater than or equal to the width of the light source in the light emitting element 22 , so as to increase the focusing effect on the light emitting element 22 .

[0137] Furthermore, the top points of the two conical structures 2141 are respectively located on both sides of the light-emitting component 22, and the distance from the second portion of the outer surface of the foam body 112 is less than or equal to the distance from the top of the light-emitting component 22 to the second portion of the outer surface of the foam body 112, thereby being able to gather and refract most of the light emitted upward by the light-emitting component 22, so that most of the light emitted by the light-emitting component 22 is refracted toward the light-emitting area 213, thereby increasing the focusing effect of the focusing structure 214 on the light emitted by the light-emitting component 22.

[0138] Preferably, the top points of the two conical structures 2141 are arranged flush with the top of the light-emitting component 22, that is, the distance between the top points of the two conical structures 2141 and the second part of the outer surface of the foam body 112 is equal to the distance between the top of the light-emitting component 22 and the second part of the outer surface of the foam body 112.

[0139] In some of the embodiments, the light emitting member 22 is at least partially arranged along the extension direction of the handle 11, and the emitted light is directed toward the driver so that the driver can feel the light of the light emitting member 22, thereby facilitating interaction between the steering wheel and the driver.

[0140] like Figure 5 and Figure 6 As shown, the light emitting element 22 includes a heat conductive pad 221, a circuit board 222 and a plurality of light elements 223. The heat conductive pad 221 is attached to the surface of the handle frame 111 exposed in the accommodation space 211, the circuit board 222 is disposed on the heat conductive pad 221, and the plurality of light elements 223 are integrated on the circuit board 222 and arranged in a linear shape.

[0141] Specifically, when the foam body 112 is molded on the outside of the handle ring skeleton 111, the handle ring skeleton 111 is exposed on the first part of the outer surface of the foam body 112, so when the thermal conductive gasket 221 is installed in the accommodating space 211, the thermal conductive gasket 221 can contact with the handle ring skeleton 111, so that the thermal conductive gasket 221 dissipates heat through the handle ring skeleton 111, that is, the heat of the thermal conductive gasket 221 is transferred to the handle ring skeleton 111.

[0142] In some of the embodiments, the thermally conductive gasket 221 and the handle ring frame 111 may cooperate with each other in shape to increase the contact area between the thermally conductive gasket 221 and the handle ring frame 111 , thereby increasing the heat dissipation capacity of the thermally conductive gasket 221 .

[0143] The connection methods between the thermally conductive gasket 221 and the handle frame 111 include but are not limited to adhesive connection, bolt connection, welding, etc.

[0144] The thermally conductive gasket 221 is made of a thermally conductive material, such as iron, aluminum, stainless steel, etc., among metal materials. The thermally conductive gasket 221 is also arranged along the extension direction of the handle 11 .

[0145] The circuit board 222 may be adhered to the thermally conductive pad 221 , so that the heat on the circuit board 222 can be transferred to the thermally conductive pad 221 as quickly as possible.

[0146] The circuit board 222 is a control circuit board, which mainly includes a microcontroller and an LED driver chip.

[0147] For example, the circuit board 222 includes a microcontroller (MCU), an LED driver chip, a power management module, a communication interface, a PCB board, etc., to realize one or more functions such as controlling the light element 223 to realize on / off lighting, lighting patterns, frequency, intensity, color, and shape of on / off lighting cycles.

[0148] The lamp element 223 may be a full-color LED lamp bead.

[0149] In some of the embodiments, Figure 7 As shown, the sensing pad 23 includes a plurality of sensing partitions 2311 , and each sensing partition 2311 can generate a corresponding sensing signal when detecting a human hand. The processing unit 25 can control the light emitting element 22 to realize a corresponding function according to different sensing signals.

[0150] Preferably, the sensing pad 23 forms the 1st, 2nd, ..., nth sensing partitions 2311 in the extension direction of the handle 11, and the 1st, 2nd, ..., nth sensing partitions 2311 are respectively used to generate the 1st, 2nd, ..., nth sensing signals, and the plurality of lamp elements 223 are divided into a plurality of groups to form corresponding 1st, 2nd, ..., nth light-emitting areas, respectively; wherein the processing unit 25 is used to correspondingly turn on the 1st, 2nd, ..., nth light-emitting areas on the light-emitting member 22 when receiving the 1st, 2nd, ..., nth sensing signals.

[0151] Among them, when the processing unit 25 receives the 1st to nth sensing signals, it can control the opening of the 1st to nth light-emitting areas on the light-emitting component 22 to realize the corresponding functions, such as at least realizing at least one or more of the on / off lighting, lighting pattern, on / off lighting cycle frequency, intensity, color and shape of the light-emitting component 22.

[0152] The processing unit 25 of the present invention can control the light emitting element 22 to realize different functions according to different sensing signals obtained, and it at least includes the following control schemes:

[0153] (1) When the processing unit 25 receives any one of the first to nth sensing signals, it can enable at least one of the first to nth light-emitting areas on the light-emitting element 22 to realize at least one function of the light-emitting element 22 .

[0154] (2) When the processing unit 25 receives any one of the first to nth sensing signals, it can enable at least two of the first to nth light-emitting areas on the light-emitting element 22 to realize at least one function of the light-emitting element 22 .

[0155] (3) When the processing unit 25 receives two sensing signals among the first to nth sensing signals, it correspondingly controls at least one of the first to nth light-emitting areas on the light-emitting element 22 to realize at least one function of the light-emitting element 22 .

[0156] (4) When the processing unit 25 receives two sensing signals among the first to nth sensing signals, it correspondingly controls at least two of the first to nth light-emitting areas on the light-emitting element 22 to implement at least one function of the light-emitting element 22 .

[0157] (5) When receiving at least one of the first to nth sensing signals, the processing unit 25 sequentially controls the first to nth light-emitting areas on the light-emitting element 22 to realize at least one function of the light-emitting element 22 .

[0158] In some of the embodiments, when the processing unit 25 receives any one of the 1st to nth sensing signals and enables at least one of the 1st to nth light-emitting areas on the light-emitting element 22 to realize at least one function of the light-emitting element 22, the sensing partition 2311 of the utility model for generating the sensing signal is spatially arranged to correspond to the front and back, top and bottom, or inside and outside of the light-emitting area that realizes at least one function of the light-emitting element 22. For example, when the first sensing partition of the sensing pad 23 sends a sensing signal, the first light-emitting area is arranged to correspond to the first sensing partition 2311 front and back, top and bottom, or inside and outside, and the first light-emitting area realizes at least one function of the light-emitting element 22.

[0159] In some of the embodiments, when the processing unit 25 receives any one of the 1st to nth sensing signals and enables at least one of the 1st to nth light-emitting areas on the light-emitting component 22 to realize at least one function of the light-emitting component 22, the sensing partition 2311 of the utility model that generates the sensing signal can be spatially offset from a light-emitting area on the light-emitting component 22. For example, when the first sensing partition of the sensing pad 23 sends a sensing signal, the first light-emitting area is offset from the first sensing partition 2311 front to back, up to down, or inside to outside, and the first light-emitting area realizes at least one function of the light-emitting component 22.

[0160] In some of the embodiments, when the processing unit 25 receives two sensing signals among the 1st to nth sensing signals and correspondingly controls at least one of the 1st to nth light-emitting areas on the light-emitting component 22 to realize at least one function of the light-emitting component 22, any one of the two sensing partitions 2311 that generate two sensing signals in the utility model can be set to correspond to the front and back, up and down, or inside and outside of the light-emitting area that realizes at least one function of the light-emitting component 22. For example, when the first sensing partition and the fourth sensing partition of the sensing pad 23 both send sensing signals, the first light-emitting area is staggered with the first sensing partition front and back, up and down, or inside and outside, and the fourth light-emitting area is staggered with the fourth sensing partition front and back, up and down, or inside and outside, and any one of the first light-emitting area and the fourth light-emitting area on the light-emitting component 22 realizes at least one function of the light-emitting component 22.

[0161] In some of the embodiments, when the processing unit 25 receives two sensing signals among the 1st to nth sensing signals and correspondingly controls at least two of the 1st to nth light-emitting areas on the light-emitting component 22 to realize at least one function of the light-emitting component 22, the two sensing partitions 2311 for generating sensing signals of the utility model can be arranged to correspond to the two light-emitting areas realizing at least one function of the light-emitting component 22 front and back, up and down, or inside and outside. For example, when the first sensing partition and the fourth sensing partition of the sensing pad 23 both send sensing signals, the first light-emitting area is staggered with the first sensing partition front and back, up and down, or inside and outside, and the fourth light-emitting area is staggered with the fourth sensing partition front and back, up and down, or inside and outside, and the first light-emitting area and the fourth light-emitting area on the light-emitting component 22 both realize corresponding light-emitting functions.

[0162] Among them, the number of sensing partitions 2311 of the sensing pad 23 can be set according to the color type or light-emitting mode of the light-emitting component 22, so that the processing unit 25 controls the light-emitting component 22 to emit light of different colors or controls the light-emitting component 22 to realize different light-emitting modes according to the sensing signal. For example, when there are 8 color types of the light-emitting component 22, the number of sensing partitions 2311 in the sensing pad 23 is also 8.

[0163] The lengths of the first to nth sensing zones 2311 on the sensing pad 23 can be flexibly set according to actual needs, so that it can cope with drivers with different hand widths or make the sensing pad 23 more flexible or interesting.

[0164] In some of the embodiments, the lengths of the first to nth sensing subareas 2311 on the sensing pad 23 are all equal, so that the driver can enable the sensing pad 23 to generate corresponding sensing signals according to needs.

[0165] Furthermore, the sensing pad 23 includes a main body 231 and a tongue portion 232. The main body 231 sequentially forms the first, second, ..., n sensing partitions 2311 along the length direction, and each sensing partition 2311 can detect a human hand and generate a sensing signal; the tongue portion 232 is arranged on the side of the main body 231, and the tongue portion 232 is used to form a control partition 2321 after being covered, and generate a control signal when a human hand is detected; when the processing unit 25 obtains the control signal, it controls the light-emitting element 22 to realize the opening and closing of the function of the light-emitting element 22.

[0166] After the sensing pad 23 covers the closed circumferential contour along the steering wheel ring 11 , the tongue portion 232 is located at the 3 o'clock direction of the steering wheel to facilitate the driver's control.

[0167] When the processing unit 25 obtains the sensing signal on the main body 231, the light emitting element 22 can be controlled to realize one or more of the on / off lighting of the light emitting area on the light emitting element 22, the frequency, intensity, color and shape of the on / off lighting cycle. When the processing unit 25 obtains the control signal, the on / off of the overall function of the light emitting element 22 can be controlled.

[0168] Furthermore, the light-emitting component 22 has multiple functions, and the processing unit 25 can control the function switching of the light-emitting component 22 according to the control signal. For example, the processing unit 25 switches the functions of the light-emitting component 22 in sequence according to the acquired control signal, such as sequentially controlling the light-emitting area on the light-emitting component 22 to realize the frequency, intensity, color and shape changes of the on / off lighting cycle.

[0169] For example, when the processing unit 25 obtains the control signal for the first time, if the sensing partition 2311 on the main body 231 detects a human hand and generates a sensing signal, the processing unit 25 can control different light-emitting areas to emit light of different colors according to different sensing signals; when the processing unit 25 obtains the control signal for the second time, if the sensing partition 2311 on the main body 231 detects a human hand and generates a sensing signal, the processing unit 25 can control the light-emitting element 22 to enter the "marquee mode" according to the sensing signal, so that the light-emitting areas on the light-emitting element 22 emit light in sequence; when the processing unit 25 obtains the control signal for the third time, if the sensing partition 2311 on the main body 231 detects a human hand and generates a sensing signal, the processing unit 25 can control the light-emitting element 22 to enter any one of the frequency, color, luminous intensity, and luminous shape of the marquee mode according to the sensing signal.

[0170] In some of the embodiments, Figure 3 As shown, the steering wheel further includes a sound-generating part 30 and a vibration part 40. The sound-generating part 30 is integrated into the steering wheel body or integrated outside the steering wheel body, and the sound-generating part 30 is used to emit a corresponding sound according to the sensing signal generated by the sensing pad 23; the vibration part 40 is integrated into the steering wheel body, and the vibration part 40 is used to vibrate correspondingly according to the sensing signal generated by the sensing pad 23.

[0171] The processing unit 25 can control the sound-generating part 30 to generate sounds of different scales according to the sensing signal generated by the sensing pad 23 .

[0172] The sound-generating part 30 and the vibration part 40 are used to generate sound or vibrate under the control of the processing unit 25 . For example, the processing unit 25 can control the sound-generating part 30 to generate sound or control the vibration part 40 to vibrate according to the sensing signal detected by the sensing pad 23 .

[0173] The vibration part 40 may be a vibration motor, and the sound-generating part 30 may be a buzzer, an external speaker, or the like.

[0174] A specific implementation method of the function of the utility model is as follows:

[0175] After power-on, long press the touch switch formed by the control partition 2321 of the tongue portion 232 of the sensing pad 23, and the processing unit 25 controls the sensing pad 23 and the light-emitting element 22 to be turned on according to the control signal;

[0176] When the touch switch is pressed once, the steering wheel vibrates and the light-emitting element 22 enters the first light-emitting mode (e.g., the processing unit 25 controls a corresponding light-emitting area on the light-emitting element 22 to emit light according to different sensing signals), and the light-emitting element 22 realizes different functions through the multiple sensing partitions 2311 on the main body 231 of the sensing pad 23;

[0177] By pressing the touch switch twice, the steering wheel vibrates and the light-emitting element 22 enters the second light-emitting mode (e.g., the processing unit controls all light-emitting areas on the light-emitting element 22 to emit light in sequence to form a marquee mode according to different sensing signals), and the light-emitting element 22 realizes different functions through the multiple sensing partitions 2311 of the main body of the sensing pad 23;

[0178] Short press the touch switch three times, the steering wheel vibrates and the light-emitting element 22 enters the third light-emitting mode (e.g., the processing unit controls all light-emitting areas on the light-emitting element 22 to emit light intermittently according to different sensing signals), so that the light-emitting element 22 can realize different functions;

[0179] Long press the touch switch 4 times to turn off the sensing function of the sensing pad 23.

[0180] The utility model is different from conventional LED lamp beads that are mounted on PCBA or FPC. By using a 360-degree thick-walled light guide strip and a stretched TIR concentrator lens 21, it can effectively achieve short-distance light uniformity and brightness, and the transition between LED lamp beads is uniform and grainless. The top of the light guide lens 21 is sprayed with matte black paint to form a shading area 212, and a 5mm light-emitting area 213 is laser-engraved directly above the TIR lens 21, which not only achieves full utilization of the light but also achieves a strip light source effect with a clear outline. The full-color LED of the annular array allows unlimited expansion space in color diversity and function of the light-emitting area, and has obvious advantages in functionality and interactivity over the pure light guide of a single lamp bead.

[0181] The sensing pad 23 of the utility model can be divided into 8 zones as a whole, representing 8 different musical scales or corresponding to the 8 colors of the light-emitting element 22, and is covered with a translucent outer light-transmitting sheath 24, so that after power-on, a long press can turn on the light-emitting element 22 and the sensing pad 23, and a short press can control the lighting mode of the light-emitting element 22. After the lighting mode is selected, the 8 sensing partitions 2311 of the sensing point can be tapped or touched to make the corresponding area display different colors, or different musical scales can be emitted by the buzzer to achieve interaction with the driver, completing the multifunctional interactive design of the steering wheel from the dimensions of hearing, touch and vision.

[0182] In this specification, the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the product embodiment described later, since it corresponds to the method, the description is relatively simple, and the relevant parts can be referred to the partial description of the system embodiment.

[0183] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
