Description

Technical Field

[0001] The utility model relates to a steering wheel with a driver health monitoring function, belonging to the technical field of steering wheels. Background Art

[0002] Bus driving is a job with high physical and mental intensity. The physical health of the driver directly affects the life safety of the passengers on the bus. Therefore, in bus management, it is necessary to pay great attention to the physical health monitoring of the driver during driving. The steering wheel is the component that the driver operates most frequently. Therefore, the existing monitoring solution is to integrate the monitoring device on the steering wheel. For example, the Chinese utility model patent with the authorization announcement number CN219257461U discloses a health detection steering wheel. At least one monitoring electrode is set on the handle of the steering wheel (i.e., the wheel rim). When the monitoring electrode contacts the driver's hand, the bioelectric current generated by the heart beat is collected and transmitted to the on-board ECU. The on-board ECU displays the results on the display mechanism through analysis and calculation, and can measure the driver's heart rate, electrocardiogram, respiratory rate, fatigue level, blood oxygen content and other vital signs indicators. In addition, a PPG sensor is also set on the wheel rim, which can detect blood flow and measure vital sign parameters such as blood oxygen value and heart rate.

[0003] The above monitoring electrodes and PPG sensors and other monitoring devices are all set on the wheel rim, the monitoring electrodes are located in the upper half of the wheel rim, and the PPG sensor is located at the bottom of the wheel rim. The driver needs to touch the corresponding position to detect, but in actual operation, the driver's hands are mostly held tightly at the intersection of the wheel rim and the spoke, that is, the junction between the left and right sides of the wheel rim and the middle spoke, so the above technical solution is inconvenient to detect. In this regard, the Chinese utility model patent with the authorization announcement number CN215322397U discloses a biometric recognition system applied to vehicles, which discloses that a sensor chip is set on the spoke of the steering wheel body, and the sensor chip is located in the area of ​​the multi-function button, which is convenient for the driver to touch for detection, but the patent does not disclose the specific installation method of the sensor chip (i.e., the monitoring device). In fact, if the monitoring device wants to be integrated on the spoke, it is necessary to consider how to install and fix it with the spoke and how to expose the button frame installed on the steering wheel body for contact detection. These are technical problems that need to be solved by those skilled in the art. Utility Model Content

[0023] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0024] In response to the technical problems faced in the prior art, the basic technical concept of the utility model is to specially set up a mounting frame for the monitoring device, so that the monitoring device can be fixed to the mounting frame, and then reserve an accommodating space for the mounting frame and the monitoring device on the button frame, so that the mounting frame can be fixed to the button frame, and then the fixed components are installed together on the spokes, wherein the button frame is provided with an exposure port for exposing the detection surface of the monitoring device, so that the driver's fingers can come into contact with the detection surface to realize the detection of vital signs indicators.

[0025] Embodiments of the steering wheel with driver health monitoring function (hereinafter referred to as steering wheel) in the utility model:

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the steering wheel includes a steering wheel body and a button frame 2 installed on the steering wheel body, and a speaker cover 3 is installed in the middle of the button frame 2. The steering wheel body includes a rim 1, a hub in the middle, and a spoke 11 connected between the rim 1 and the hub. In this embodiment, the spoke 11 connected to the right side of the rim 1 is integrated with a monitoring device 5 (i.e., a sensor) for monitoring the driver's physical health. The monitoring device 5 sends infrared light and visible light to the skin, and then receives the reflected light. Due to the real-time pulsation characteristics of the capillaries under the skin, the reflected light will have slight differences. The sensor will sensitively capture these slight differences, and then combine biology, medicine and optics to perform algorithm calculations to calculate the driver's heart rate, diastolic blood pressure, systolic blood pressure, blood oxygen, microcirculation and other health data.

[0027] The steering wheel also includes a mounting frame 4, and the monitoring device 5 is fixed on the mounting frame 4. The specific fixing method is as follows: Figure 5 As shown, the mounting frame 4 includes a cover plate 4-1, and the cover plate 4-1 has an outer surface ( Figure 5 The downward facing surface is for easy observation. Figure 5 The monitoring device 5 is an inverted structure. The monitoring device 5 is fixed on the inner side of the cover plate 4-1. The cover plate 4-1 is provided with a through hole 4-2 exposing the detection surface of the monitoring device 5. The inner side of the cover plate 4-1 is provided with a ring body 4-3 extending inward at the position of the through hole 4-2. One end of the monitoring device 5 provided with the detection surface is inserted into the ring body 4-3. At the same time, a first fixing column 4-4 is provided on the inner side of the cover plate 4-1 and outside the ring body 4-3. The monitoring device 5 is fixed to the first fixing column 4-4 by a first screw 7. The first fixing column 4-4 is provided with a threaded hole matched with the first screw 7. There are two first fixing columns 4-4, which are arranged in sequence in the length direction of the ring body 4-3. Connecting plates are respectively provided on both sides of the end of the monitoring device 5. The connecting plates are provided with U-shaped grooves 5-1. The first screw 7 passes through the U-shaped groove 5-1 and is connected to the first fixing column 4-4, which facilitates the installation and fixation of the monitoring device 5.

[0028] like Figure 2 and Figure 3 As shown, the key frame 2 is provided with a space for accommodating the mounting frame 4 and the monitoring device 5, and the key frame 2 is also provided with an exposure opening 2-1 for exposing the outer surface of the cover plate 4-1, so that the exposure opening 2-1 also exposes the detection surface of the monitoring device 5. In order to facilitate fixing the mounting frame 4 on the key frame 2, as shown in FIG. Figure 5 As shown, a circle of inwardly extending extension edge 4-5 is provided on the inner edge of the cover plate 4-1, and four L-shaped fixing ear plates 4-6 are arranged at intervals. The fixing ear plates 4-6 include a fixing portion and a connecting portion that are vertically connected, wherein the connecting portion is connected to the extension edge 4-5 of the cover plate 4-1, and the fixing portion extends out of the edge of the cover plate 4-1 and is fixed by a second screw 9 ( Figure 4 As shown in the figure) is fixed on the key frame 2. Therefore, Figure 2 and Figure 3 As shown, a second fixing column 2-2 corresponding to the fixing ear plate 4-6 is provided on the inner side of the key frame 2, and a threaded hole matched with the second screw 9 is provided on the second fixing column 2-2. The second fixing column 2-2 has a certain length, so that after the fixing portion of the fixing ear plate 4-6 abuts against the second fixing column 2-2, the outer surface of the cover plate 4-1 is just aligned with the exposure opening 2-1, which ensures fixation without affecting the appearance.

[0029] In addition, as an implementation method, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the steering wheel also includes a circuit board 6 for connecting to the vehicle-mounted terminal. A third fixing column 4-7 is provided on the inner side of the cover plate 4-1, and the circuit board 6 is fixed to the third fixing column 4-7 by a third screw 8. Two third fixing columns 4-7 are provided, and each third fixing column 4-7 is provided with a threaded hole that cooperates with the third screw 8. At the same time, a positioning column 4-8 is also provided on the inner side of the cover plate 4-1, and a corresponding positioning hole is provided on the circuit board 6 to facilitate the positioning and installation of the circuit board 6. The length of the third fixing column 4-7 is greater than the length of the first fixing column 4-4, so that the circuit board 6 is located on the inner side of the monitoring device 5 after being fixed on the third fixing column 4-7, and the circuit board 6 is connected to the monitoring device 5 signal, and the circuit board 6 processes the monitoring signal and transmits it to the vehicle-mounted terminal.

[0030] Of course, in other embodiments, such as Figure 1As shown, the middle part of the steering wheel body (i.e., inside the wheel hub) can be provided with a signal processing module 10 for connecting to the vehicle terminal, and the monitoring device 5 is directly connected to the signal processing module 10 through a wiring harness. When in use, the driver gently places his finger on the detection surface of the monitoring device 5 in a calm state (no light leakage), and then the monitoring device 5 starts monitoring and transmits the monitoring data to the signal processing module 10. The signal processing module 10 converts the processed data (mainly eliminating invalid data, balancing data with large jumps, etc., and then converts the data after comprehensive analysis) or the original data into a CAN message and sends it to the human-computer interaction display screen (including but not limited to the combination instrument, central control screen, head-up display, etc.), and transmits it to the vehicle terminal at the same time. After the human-computer interaction display screen is integrated with other vehicle information and health monitoring data, it performs functions such as step prompts and health result display of the driver monitoring process locally, and transmits the information to the vehicle terminal at the same time. The vehicle terminal transmits the data to the cloud platform through a wireless channel (including but not limited to 4G / 5G), and the cloud platform performs comprehensive driver health platform management and alarm reminders.

[0031] In order to facilitate the driver's finger to contact the detection surface of the monitoring device 5 and to be more ergonomically designed, the monitoring device 5 in this embodiment is arranged tilted, such as Figure 1 As shown, line B is the longitudinal center line of the steering wheel, line B' is a line parallel to the longitudinal center line of the steering wheel, line C is the longitudinal center line of the monitoring device 5, and the angle between line B' and line C is A. When the monitoring device 5 is horizontal (i.e. A=90°) or the monitoring device 5 is vertical (i.e. A=0°), the ergonomic effect is not optimal. Therefore, in the utility model, it is 20°~40°, preferably 30°. Of course, it can also be 20° or 40° in other embodiments.

[0032] When assembling the steering wheel of the utility model, the monitoring device 5 and the circuit board 6 are first fixed to the mounting frame 4 by corresponding screws, and the signals of the two are connected. Then, the mounting frame 4 is fixed to the key frame 2 by the second screw 9, and finally the fixed overall assembly is buckled onto the steering wheel body. Therefore, a plurality of buckles are provided on the key frame 2, and corresponding card slots are provided on the steering wheel body. Of course, in order to facilitate processing and manufacturing, the key frame 2 and the mounting frame 4 are both injection molded.

[0033] In other embodiments of the steering wheel with a driver health monitoring function: when the mounting frame is fixed to the inner side of the button frame by a fixing ear plate, the second fixing column may not be provided on the button frame, but a threaded hole may be directly provided by utilizing the wall thickness of the button frame itself to achieve connection with the second screw.

[0034] In other embodiments of the steering wheel with a driver health monitoring function: the inner edge of the cover plate may not be provided with an inwardly extending extension edge, and in this case the fixed ear plate is directly connected to the inner wall of the cover plate.

[0035] In other embodiments of the steering wheel with the driver health monitoring function: three L-shaped fixed ear plates can also be provided, and there should be at least two. Of course, five or six can also be provided depending on the specific size of the circuit board.

[0036] In other embodiments of the steering wheel with driver health monitoring function: the fixing method of the cover plate and the key frame may not be to set a fixing ear plate on the cover plate and fix it to the key frame by a second screw, but to set a buckle on the cover plate, and the cover plate is installed on the key frame by a buckle. Of course, in other embodiments, the cover plate may not be set with a buckle or a fixing ear plate, but directly fixed to the key frame by bonding the outer edge.

[0037] In other embodiments of the steering wheel with driver health monitoring function: for the fixing method of the monitoring device, the cover plate may not be provided with a first fixing column, but a threaded hole may be directly provided by using the wall thickness of the cover plate itself to achieve connection with the first screw. Of course, in other embodiments, the monitoring device may also be fixed to the cover plate by bonding, and in this case, the first fixing column is not required.

[0038] In other embodiments of the steering wheel with driver health monitoring function: the inner side of the cover plate may not be provided with a ring body. For example, for a relatively thin sensor, it is only necessary for the cover plate to have a through hole to expose the detection surface.

[0039] In other embodiments of the steering wheel with driver health monitoring function: the mounting frame can also be a shell structure with surrounding side walls. Of course, the mounting frame can also be a frame structure. Regardless of the form of the mounting frame, after the monitoring device is fixed on the mounting frame, the mounting frame can be located on the inner side of the monitoring device. For example, the monitoring device is fixed on the outer end face of the mounting frame or on the plane where the outer end is located. At this time, it is only necessary to provide an exposure opening on the button frame to expose the detection surface of the monitoring device, without exposing any part of the mounting frame.

[0040] In other embodiments of the steering wheel with driver health monitoring function: the accommodating space for accommodating the mounting frame and the monitoring device can be set only on the spoke, and the monitoring device only needs to satisfy that the detection surface is exposed from the exposure opening on the button frame. Of course, in other embodiments, the accommodating space can also be set on the button frame and the spoke, each occupying half.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
