[0002] Due to the rapid development of the automobile industry, the number of cars on the market has continued to rise. The surge in the number of vehicles on the road has led to frequent traffic accidents. Especially in the case of long-term driving, the driver often leaves the steering wheel. In order to monitor the driver's operating status during driving and avoid and reduce the occurrence of traffic accidents caused by the driver's improper operation during driving, many cars are now equipped with a hands-off detection function when they leave the factory.

[0003] New vehicles, especially new energy vehicles, are generally equipped with a hands-off detection function when they leave the factory. However, for vehicles with a hands-off detection function installed later, the steering wheel needs to be modified to implement the function. On the one hand, the modification operation is very cumbersome and requires disassembly of the steering wheel, which inevitably causes certain damage to the vehicle. On the other hand, adding a hands-off detection function requires consideration of the installation of the controller. Since the area near the steering wheel is relatively sensitive, the installation of the controller is also difficult, the installation efficiency is low, and it is difficult to popularize.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0055] The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings in the embodiments of the present application.

[0056] Example 1

[0057] This embodiment provides a control box, which is applied to the after-installed device on the steering wheel. It can be connected to the after-installed device on the steering wheel. While providing power to the after-installed device, it can also establish electrical signal transmission with the after-installed device to ensure the normal operation of the functions of the after-installed device.

[0058] like Figure 1 and Figure 2 As shown, the control box of this embodiment can be a controller 100, or a housing in which the controller 100 is installed. The controller 100 is an independent device that can be detachably mounted on the steering wheel. The controller 100 can be mounted on the upper surface or the lower surface of the steering wheel, and can be mounted on the spokes or rim of the steering wheel according to actual needs.

[0059] The controller 100 is electrically connected to the aftermarket device to power it. It also receives electrical signals from the aftermarket device and transmits status signals to the external device to ensure the normal functioning of the aftermarket device. These status signals include detection signals and grip posture information. In some embodiments, the controller also transmits power level signals, control information, and other information to the external device.

[0060] In some embodiments, the status information may be stored in a server or other electronic device for subsequent information collection and analysis.

[0061] The after-installed equipment mentioned in this embodiment can be a functional component installed on the steering wheel after the vehicle leaves the factory, such as a steering wheel cover, a steering wheel heating device, or a display device installed on the steering wheel, or an electrocardiogram monitoring device installed on the steering wheel, etc.

[0062] The control box of this embodiment can be independently installed on the steering wheel, ensuring that the after-market equipment can be directly installed on the steering wheel without the need to disassemble the steering wheel or the vehicle. The controller 100 is independently designed and separated from the vehicle body control device. There is no need to install the controller of the after-market equipment into the vehicle body, thereby avoiding the need to disassemble and install the vehicle such as the central control area. The control box of this embodiment realizes the instant disassembly and installation of the after-market equipment, is simple and convenient to install, and has high installation efficiency. It can be widely used for the installation of after-market equipment after the vehicle leaves the factory, has a wide range of adaptability, and has good market prospects.

[0063] In one embodiment, Figure 6 As shown, the control box includes a power module 110, which provides power to the controller 100. The control box can be completely removed from the steering wheel for charging. If the control box does not need to be removed, the power module 110 can be directly connected to a charging power source for charging. The power module 110 can also be designed to be detachably connected to the controller 100, allowing the power module 110 to be removed from the control box for charging.

[0064] In one embodiment, the controller 100 has a communication function and can communicate with mobile devices such as vehicle multimedia or mobile phones or vehicle controllers. The communication here can be wireless communication, such as Bluetooth communication. The controller 100 uses the communication function to connect the execution status of the after-installed device with the vehicle multimedia, vehicle controller or mobile phone to achieve human-computer interaction.

[0065] Regarding the specific installation structure and charging structure of the controller 100, the following embodiments will further introduce the structure of the control box in combination with the application scenario of the control box.

[0066] Example 2

[0067] This embodiment applies the control box mentioned in the above-mentioned embodiment 1 to the steering wheel hands-off detection device, and provides a steering wheel hands-off detection kit, which includes a control box used on the steering wheel and after-installed equipment. Specifically, the after-installed equipment in this embodiment is a steering wheel cover 400.

[0068] The steering wheel cover 400 in this embodiment is a steering wheel cover with an HOD detection function. A HOD sensing layer is provided inside the steering wheel cover. The HOD sensing layer is electrically connected to the controller 100 in the control box and can send an electrical signal to the controller 100 in response to an object contacting or separating from the surface of the steering wheel cover 400. The controller 100 determines whether the steering wheel cover 400 is contacted based on the received electrical signal, and then detects the hands-off state of the steering wheel.

[0069] In this embodiment, the steering wheel hands-off detection kit mainly consists of two parts: a steering wheel cover 400 and a control box. When in use, the steering wheel cover 400 is directly mounted on the rim 303 of the steering wheel, and the control box is installed on the spokes 301 or rim 303 of the steering wheel.

[0070] In one embodiment, in order to achieve the installation of the control box, as Figure 1 As shown, the control box includes a base 200 and a controller 100. The base 200 is set on the steering wheel, and the controller 100 is detachably mounted on the base 200 to achieve the installation of the controller 100 and the steering wheel.

[0071] The installation position of the base 200 should be considered such that after the controller 100 is installed, the controller 100 and the base 200 should not affect the driver's normal grip on the steering wheel to ensure driving safety.

[0072] Therefore, this embodiment provides a solution for installing the base 200 , where the base 200 is installed on the back of the spoke 301 of the steering wheel.

[0073] like Figure 1 and Figure 2 As shown, the base 200 is installed on the back side of the steering wheel spoke 301, that is, the surface of the steering wheel spoke 301 facing away from the driver. Preferably, the length and width of the base 200 and the controller 100 are smaller than the size of the steering wheel spoke 301. In this way, the base 200 and the controller 100 not only occupy a small volume of the steering wheel, so that the driver will not touch them when holding the steering wheel, ensuring driving safety, but also can be hidden under the steering wheel to ensure the beauty of the steering wheel.

[0074] In one embodiment, the surface of the base 200 facing the steering wheel spokes 301 is shaped to conform to the contact surface of the steering wheel spokes 301, thereby ensuring that the base 200 is stably attached to the steering wheel spokes 301. For example, the back of the spokes 301 of some steering wheels is an arched surface. The bottom surface of the base 200 is designed to be concave to match the arched surface of the spokes 301, thereby increasing the contact surface between the base 200 and the back of the spokes 301 and improving stability.

[0075] In this embodiment, the base 200 can be directly glued to the back of the steering wheel spoke 301 by strong glue, and can also be fixed to the back of the steering wheel spoke 301 by connecting members such as screws.

[0076] In one embodiment, in order to achieve a detachable connection between the controller 100 and the base 200 , a quick-release structure is provided on the side of the base 200 facing away from the steering wheel spokes 301 , and the controller 100 is mounted on the base 200 via the quick-release structure.

[0077] like Figure 3 As shown, the quick-release structure is a sliding groove 210 provided on the surface of the base 200 , and the controller 100 is inserted into the sliding groove 210 in a sliding manner.

[0078] Specifically, there are paired blocks 211 on both sides of the sliding groove 210, and the housing of the controller 100 is provided with a block 211 on both sides. When installing the controller 100, the block 101 on both sides of the controller 100 corresponds to the block 211 on both sides of the sliding groove 210, and the controller 100 is directly inserted into the base 200 along the sliding groove 210. When removing the controller 100, it is only necessary to pull the controller 100 out from one side of the base 200. This design realizes simple and fast assembly and disassembly of the controller 100, and high assembly efficiency. Of course, in some embodiments, the two sides of the controller 100 can be set as blocks, and the corresponding two sides of the base 200 are formed with a block slot, which can also realize the sliding and detachable installation of the controller 100 and the base 200.

[0079] It is worth mentioning that, since the steering wheel spokes 301 are generally not on a plane and the base 200 is not arranged horizontally, the controller 100 may become loose or even fall when installed in the sliding groove 210. Preferably, the slot 101 and the block 211 can be designed to have an interference fit to increase the frictional resistance between the controller 100 and the sliding groove 210, thereby preventing the controller 100 from becoming loose or falling. Of course, a buckle or damping structure can also be provided between the controller 100 and the sliding groove 210 to prevent the controller 100 from sliding and improve the installation stability of the controller 100.

[0080] In this embodiment, a male and female connector 410 is provided between the controller 100 and the steering wheel cover 400. The male and female connector 410 is used for electrical connection between the controller 100 and the steering wheel cover 400, and can realize a detachable connection between the controller 100 and the steering wheel cover 400.

[0081] like Figure 3 and Figure 6As shown, in one embodiment, the male and female connectors 410 are spring connectors 411 arranged on the surface of the steering wheel cover 400, and the contact 121 is arranged on one side of the controller 100. The spring connector 411 protrudes from the surface of the steering wheel cover 400 and extends toward the steering wheel spoke 301. When the controller 100 is installed on the base 200, the contact 121 faces the spring connector 411 and is connected to the spring connector 411.

[0082] like Figure 3 As shown, in one embodiment, the base 200 is arranged at a position close to the rim 303 of the steering wheel spoke 301, the extension direction of the sliding groove 210 is consistent with the extension direction of the spring connector 411, and the spring connector 411 extends into the sliding groove 210, so that the controller 100 is inserted into the sliding groove 210 from one side of the sliding groove 210. When the controller 100 is inserted into the expected fixed position, the contact piece 121 of the controller 100 is just in contact with the spring connector 411. When the controller 100 is installed and fixed, it is electrically connected to the steering wheel cover 400.

[0083] Preferably, at least one of the controller 100 and the steering wheel cover 400 has a magnetic force, so that the contact piece 121 and the spring connector 411 are connected by magnetic attraction when they are close together. For example, the housing of the controller 100 is made of metal, and the steering wheel cover 400 has a magnet near the spring connector 411. When the two are close together, they can attract each other. This not only facilitates the quick connection of the spring connector 411 and the contact piece 121, but also improves the connection strength between the controller 100 and the steering wheel cover 400, preventing the controller 100 from loosening.

[0084] Of course, in some embodiments, the control box may not include the base 200, and may only include the controller 100. If it is not necessary to easily remove the controller 100 from the steering wheel, the controller 100 may be glued or bolted to the back of the spoke 301 of the steering wheel.

[0085] Example 3

[0086] This embodiment provides a steering wheel hands-off detection kit, which includes the control box and steering wheel cover 400 mentioned above, and provides another installation method of the controller 100 on the steering wheel.

[0087] like Figure 4 As shown, in this embodiment, the controller 100 is installed on the inner ring of the steering wheel rim 303. In this way, the driver's hands are not likely to touch the controller 100 when turning the steering wheel, and the space on the steering wheel is reasonably utilized.

[0088] In this embodiment, one side of the controller 100 has a curved surface that approximates the curvature of the steering wheel rim 303, and the controller 100 abuts against the inner surface of the steering wheel rim 303 via the curved surface. The controller 100 is designed to be as curved as possible to minimize the space occupied by the controller 100 in the hollow area of ​​the steering wheel and prevent the controller 100 from blocking the driver's view of the instrument panel.

[0089] In one embodiment, the controller 100 may be glued to the inner side of the steering wheel rim 303 or may be tied to the inner side of the steering wheel rim 303 .

[0090] like Figure 4 As shown, the controller 100 is tied to the steering wheel rim 303 by two cable ties 700. When the steering wheel cover 400 is put on the steering wheel rim 303, the steering wheel cover 400 includes the cable ties 700 to ensure the appearance. The controller 100 is located on the inner side of the steering wheel rim 303 and does not affect the installation of the steering wheel cover 400. The connection of the cable ties 700 is simple and convenient, low cost, and the controller 100 can be easily disassembled.

[0091] In this embodiment, the electrical connection between the controller 100 and the steering wheel cover 400 can also adopt the male and female connectors 410 mentioned above, and can also be connected in a magnetic way, which will not be repeated in this embodiment.

[0092] Alternatively, the controller 100 has a wiring port, and the controller 100 and the steering wheel cover 400 are connected using a wiring harness.

[0093] Example 4

[0094] This embodiment provides a hands-off steering wheel detection kit, which provides a specific charging structure for a controller 100 based on the above-mentioned embodiments 2 and 3.

[0095] like Figure 6 As shown, the controller 100 of this embodiment includes a power module 110 and a detection module 120. The detection module 120 is electrically connected to the steering wheel cover 400 and is used to process the signals generated by the steering wheel cover 400 to detect and determine the hands-off state of the steering wheel. The power module 110 is electrically connected to the detection module 120, and the surface of the power module 110 is provided with a charging port 111 for connecting to an external power source.

[0096] In this embodiment, the power module 110 and the detection module 120 can be an integrated structure. When the controller 100 is fixed to the steering wheel, it can be directly charged through the charging interface 111 of the power module 110. When the controller 100 is detachably connected to the steering wheel, the controller 100 can be removed as a whole for charging.

[0097] like Figure 5As shown, the power module 110 can also be connected to an external power source for charging via the wiring port 102 connected to the wire 600. The power module 110 can be configured with charging logic, for example, when the nickel-metal hydride battery power is less than 30% to start charging, to ensure that the hands-off detection function of the steering wheel cover 400 is always on.

[0098] It is worth mentioning that while removing the controller 100 for charging provides convenience, it also creates a problem: the user can easily remove the controller 100 when charging is needed. This removes the detection module 120, potentially leading to the user violating the one-to-one agreement between the detection module and the vehicle and using the device on another vehicle, causing more disputes for the insurance company. Furthermore, different calibration values ​​for different vehicles can lead to data errors. Therefore, to address this issue, the power module 110 and the detection module 120 can be separated.

[0099] like Figure 6 As shown, in one embodiment, the power module 110 and the detection module 120 are designed to have compatible shapes and are detachably connected via a snap-on connection. When the controller 100 needs to be charged, only the power module 110 can be removed from the detection module 120, while the detection module 120 remains connected to the steering wheel cover 400, preventing misappropriation.

[0100] In some embodiments, the controller 100 includes not only a power module 110 and a detection module 120, but also a communication module. This module provides communication functionality for the controller 100, enabling communication with mobile devices such as mobile phones. This communication can be wireless, such as Bluetooth. The controller 100 communicates with electronic devices or vehicles via the communication module to display at least one of the controller's current power level, detection information, and signal information, thereby enhancing the intelligence of the hands-off steering wheel detection kit.

[0101] like Figure 6 As shown, in one embodiment, the power module 110 is further provided with an indicator light 112 on its surface for displaying the power level information of the power module 110 and one or more of the charging status and the connection status. For example, the indicator light 112 includes a green light and a yellow light. When the green light is on, it indicates that the wireless connection is successful. When the yellow light is on, it indicates that the wireless connection is disconnected. When the green and yellow lights flash alternately, it indicates that the connection between the controller and the after-installed electronic device is unsuccessful. When both the green and yellow lights are off, it indicates that the power module 110 is not charging.

[0102] The charging interface 111 in this embodiment can be a Type-C interface, or any other interface. The power module 110 and the detection module 120 can be connected via a 4-pin spring connector.

[0103] Example 5

[0104] This embodiment provides a hands-off steering wheel detection kit and another charging structure for the controller 100 .

[0105] In this embodiment, when the power module 110 is not disassembled, the power module 110 can be connected to an external power source through a movable connector for charging.

[0106] like Figure 7 As shown, the movable connector can be two magnetic absorption buckles 503, one of which is connected to the power module 110 via a wire 600, and the other is connected to an external power source or a cigarette lighter interface in the car via a wire 600, and is charged using the cigarette lighter interface in the car.

[0107] The magnetic reel 503 of this embodiment has two functions. First, the magnetic reel 503 can reel in the wire 600 and can freely adjust the length of the wire 600 to prevent the wire 600 from being too long or too short and affecting the rotation of the steering wheel. Second, the two magnetic reels 503 are connected by a magnetic plug. When charging is required, the driver can charge by plugging the two magnetic reels 503 together. When charging is not required, the driver only needs to unplug the two magnetic reels 503. The magnetic reel 503 will automatically reel in to prevent the wire 600 from interfering with the steering wheel movement.

[0108] Since repeated plugging and unplugging of the magnetic buckle 503 may cause fatigue of the plug structure, reduce the service life, and easily lead to situations such as forgetting to charge, this embodiment can also be designed for free charging.

[0109] Furthermore, this embodiment also improves the movable connector. The movable connector is designed to maintain power supply in response to the steering wheel in a straight-ahead state, and to disconnect power supply in response to the steering wheel in a turning state. In this way, the driver does not need to worry about the charging status of the power module 110, and the power module 110 is automatically charged.

[0110] Specifically, such as Figure 8 As shown, the movable connector includes a first connecting buckle 501 and a second connecting buckle 502. The first connecting buckle 501 is connected to the power module 110 through a wire 600, and the second connecting buckle 502 is connected to an external power source or a cigarette lighter interface in the car through a wire 600.

[0111] The first connecting buckle 501 is fixed on the spoke 301 of the steering wheel and can be set at the bottom of the spoke 301 of the steering wheel near the steering wheel mounting seat 302. The second connecting buckle 502 is fixed on the mounting seat 302. The positions of the first connecting buckle 501 and the second connecting buckle 502 are adjusted so that the two can switch between contact and separation when the steering wheel rotates. In this way, when the steering wheel rotates, the first connecting buckle 501 follows the steering wheel and is connected to the second connecting buckle 502 when the steering wheel is in a straight state, and the power module 110 enters a charging state. When the steering wheel is in a turning state, the first connecting buckle 501 and the second connecting buckle 502 are staggered, and the charging state of the power module 110 is disconnected.

[0112] Such a design avoids the problem of the plug being damaged due to frequent plugging and unplugging and forgetting to charge. In addition, the design does not require attention to the charging problem of the controller 100, and is particularly suitable for use in vehicles.

[0113] In the embodiments of the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," or "above" a second feature may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," or "below" a second feature may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is lower in level than the second feature.
