Description
Technical Field
[0001] The utility model relates to the technical field of motor vehicle driving training, in particular to a vehicle handle detection device, which can monitor and evaluate the state of a motorcycle handle in real time to ensure the driver's safe operation under different driving conditions. Background Art
[0002] With the increasing popularity of motorcycles as a means of transportation, the safety of motorcycle driving is attracting increasing attention. The driving environment and operating requirements of motorcycles determine certain safety risks. The driver's grip is particularly important when driving at high speeds, in adverse weather conditions, or for long periods of time. Grip operation directly affects the stability of the motorcycle and the driver's comfort, which in turn affects driving safety.
[0003] Currently, the monitoring of motorcycle handlebars mainly relies on touch sensing. Although this method can detect the status of motorcycle handlebars to a certain extent, it still has many shortcomings.
[0004] Touch sensing is sensitive to humidity. Due to the detection characteristics of its sampling capacitor, water on the handle will reduce the sampling reliability or the stability of the sampled data. When used in southern China in the summer, the weather is hot and some people's hands are prone to sweating, resulting in abnormal touch sensing. Similar stability issues will also occur in rainy or snowy weather.
[0005] Limitations of sensing distance: Touch sensing uses the detection characteristics of capacitance, which limits the distance at which the handle can be held on the sensor. If you hold the handle with gloves, the detection accuracy or stability may be reduced. In northern cities in China, the weather is cold in winter, and gloves are unavoidable, which affects the accuracy of detection.
[0006] In the second and third subjects of the motorcycle driving test, gripping the handlebars with both hands is an important part of the process. When taking the road driving test, students need to grip the handlebars with both hands, and they may wear gloves. The situation is changeable. Currently, there is a lack of a device with good performance and low cost to detect the situation of students gripping the handlebars with both hands during riding. In addition, the use of touch sensing to sample the grip status is easily affected by rainy and snowy weather or wearing gloves, resulting in unstable sampling data. Utility Model Content

[0033] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
[0034] See also Figure 1 In this embodiment, a vehicle handle detection device is provided, including a light-sensing component 100 and a fixing component 200. The light-sensing component 100 is provided in plurality, and the plurality of light-sensing components 100 are mounted on the fixing component 200. The light-sensing component 100 is fixed by the fixing component 200 and applied to the handle. The light-sensing component determines the state of the handle being held by detecting changes in light intensity. The structure is simple in design and installation is convenient and easy. The original vehicle handle state is not changed, and the sensory characteristics of the driver holding the handle are not affected. In addition, the handle detection can be performed in a visible environment to the human eye.
[0035] In this embodiment, the photosensitive component 100 includes a photosensitive component 110 and a circuit board 120. The circuit board 120 is provided with at least one or more photosensitive components 110. At least one or more photosensitive components 110 are assembled on the circuit board 120 through a welding process. An external wiring welding point is led out at one end of the circuit board 120 for later connection with an external data processing unit. The photosensitive components 110 can be evenly distributed on the circuit board 120 or the gap can be adjusted according to actual conditions.
[0036] In this embodiment, the circuit board 120 may be a PCB (conventional circuit board) or an FPC (flexible circuit board).
[0037] See also Figure 2 As shown, in another embodiment, the photosensitive component 100 uses a photosensitive plate. The photosensitive plate itself has photosensitivity characteristics, and the photosensitivity characteristics are distributed on the photosensitive plate. No external photosensor device is required. It is sensitive to light, resulting in changes in resistance, voltage or current on the photosensitive plate. An area on one side of the photosensitive plate is connected to an external data processing unit to transmit the response of the photosensitive plate to changes in light intensity.
[0038] It should be understood that the light-sensing component 100 uses other optical sensing devices to detect changes in light intensity, including visible light and invisible light. The optical sensing device can be an electronic device with voltage-type, resistance-type or current-type changes, or an electronic device that simultaneously contains one or more characteristics of voltage-type, resistance-type or current-type changes, including phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, photocells, etc., and a diversified layout can be implemented according to the needs of the application scenario to adapt to actual needs.
[0039] See Figure 3-4 As shown, in one embodiment, a groove 210 is opened inside the fixing component 200, and the depth of the groove 210 is equivalent to the thickness of the circuit board 120 or the flexible circuit board, so that the light sensing component 100 is on the same plane as the inner plane of the fixing component 200 after installation.
[0040] Furthermore, a hole 220 is provided on the fixing component 200 , and the hole 220 corresponds to the position of the light sensing component 110 .
[0041] In the specific implementation, the photosensitive component 100 is installed in the groove 210, the photosensitive component 110 passes through the hole 220, and the outer planes of the photosensitive component 110 and the fixed component 200 are in the same plane. During the installation process, the measurement harness is led out and connected to the external measurement logic unit to maintain the overall appearance and avoid abnormal holding feel caused by uneven thickness.
[0042] See Figure 5-6 As shown, further, the fixing component 200 is a hollow columnar structure, and an opening 230 is provided on the fixing component 200. In specific implementation, the opening 230 is clamped on the handle component 400, and the fixing component 200 is squeezed to deform and sleeve on the handle component 400. By rotating the fixing component 200, the layout of the light-sensing component 100 can be changed according to actual site needs to meet actual needs and achieve better use effects.
[0043] The fixing component 200 and the light sensing component 100 can be directly fixed on the handle component 400 and can meet normal use in outdoor environments.
[0044] In this embodiment, the fixing component 200 adopts a silicone fixing component, which is made of a translucent silicone material. A groove is opened on the inner plane of the silicone fixing component to fix the light-sensitive component 100. The light-sensitive component 100 is fixed on the silicone fixing component and can be directly installed on the grip component 400 to be tested without the need for secondary external fixation. Light is irradiated on the light-sensitive component 100 through the transparent silicone fixing component. When the trainee holds the grip component 400, the gripping condition of the vehicle grip component 400 is judged through external data analysis.
[0045] See Figure 7As shown, in one embodiment, a fixing component 200 and a photosensitive component 100 are provided, the fixing component 200 and the photosensitive component 110 in the photosensitive component 100 are in the same plane, and the outer plane of the photosensitive component 110 and the outer plane of the fixing component 200 are in the same plane.
[0046] See Figure 8 As shown, in another embodiment, a fixing component 200 and a photosensitive component 100 are further provided, and the photosensitive component 110 in the photosensitive component 100 extends to the outside of the fixing component 200, and the outer plane of the photosensitive component 110 and the outer plane of the fixing component 200 are in the same plane.
[0047] See Figure 9 As shown, it can be understood that light-sensing components 110 are used to detect changes in light intensity. The more light-sensing components 110 there are, the higher the detection accuracy is. However, this also faces the problem of increased cost or increased difficulty in wiring. Therefore, in a specific implementation, a layout of light-sensing components 110 is provided, and at least one light-sensing component 110 is provided at the grip of each finger of the driver to detect whether the grip position of each finger of the driver is accurate. At least one light-sensing component 110 is provided at the grip of the palm of the driver to detect whether the grip position of the palm of the driver is accurate, thereby improving the detection accuracy while reducing the cost as much as possible.
[0048] In a specific embodiment, a gripping area is formed on the handle, and the number of the light sensing components 110 corresponding to the coverage of the gripping area is set. The coverage of the gripping area includes high, medium and low levels, and the number of the light sensing components 110 is set in one-to-one correspondence with the levels of the coverage.
[0049] The coverage of the gripping area, including high, medium and low, is actually determined according to the coverage of the palm and fingers on the grip. Generally, the palm coverage surface is opaque and is the key detection area, so the number of sensor components 110 set is large, and the coverage of the middle of the finger is lower than the palm coverage, so the number of sensor components 110 set is lower than the number of sensor components 110 set in the palm area, and the coverage of the finger near the end position is lower than the coverage of the middle of the finger, so the number of sensor components 110 set is lower than the number of sensor components 110 set in the middle of the finger.
[0050] This layout can avoid misjudgments due to light leakage, improve detection accuracy, and achieve lower power consumption. If arranged in a matrix, it will inevitably lead to higher power consumption.
[0051] Furthermore, the control algorithm for the sensor components 110 assigns a higher recognition weight to the palm coverage area, which generally corresponds to the driver-facing side of the handlebar. This is followed by the mid-finger coverage area, and then the fingertips near the end. This allows for higher detection accuracy while reducing the number of sensor components 110 and lowering power consumption.
[0052] It should be understood that in the above embodiment, only the fixing component 200 is used to fix the photosensitive component 100, which has poor stability and poor protection for the fixing component 200 and the photosensitive component 100, and cannot achieve the waterproof and dustproof effect.
[0053] See Figure 10 As shown, in one embodiment, a fastening component 300 is further provided, which is wrapped around the outside of the fixing component 200. After wrapping the fixing component 200, the fixing component 200 is made more stable.
[0054] In a specific embodiment, the fastening component 300 uses a silicone transparent heat shrink tube. After the fixing component 200 and the light-sensing component 100 are assembled and the installation position is determined, the silicone transparent heat shrink tube is installed and the silicone transparent heat shrink tube is heat-shrunk using a hot air gun so that the silicone transparent heat shrink tube can tightly fix the internal fixing component 200 and the light-sensing component 100. Light can directly pass through the transparent silicone heat shrink tube and shine on the light-sensing component 110, and then the external logic measurement unit determines whether there is a grip state based on the intensity of the incoming light.
[0055] Specifically, the fixing component 200 and the light sensing component 100 are fixed by the fastening component 300, so that the driver's gripping state of the handle will not be affected by water soaking in the handle in rainy or snowy days or wearing gloves, which will cause unstable sampling data.
[0056] Furthermore, the transparent silicone heat shrink tubing uses other light-transmitting materials, including visible light or invisible light or light of a characteristic wavelength.
[0057] Furthermore, a protruding structure or an anti-slip structure may be provided on the fastening component 300. Specifically, a protruding structure or an anti-slip structure may be provided on the transparent silicone heat shrink tube to increase the friction of the grip.
[0058] In addition, in another embodiment, the photosensitive component 100 and the fixing component 200 are replaced by flexible conductive materials, the photosensitive component 110 is welded on the flexible conductive material, and the transparent silicone heat shrink tube is grooved inside for placing the flexible conductive material and the photosensitive component 100.
[0059] In this embodiment, the flexible material integrates the light collection function and is directly mounted on or attached to the handle component 400 to be tested.
[0060] In one embodiment, a grip is also provided, including a grip component 400 equipped with the above-mentioned grip detection device, and is also connected to an external data processing unit, including a wired connection or a wireless connection. The data processing unit scans each point on the grip component 400 in turn through polling to achieve data sampling of the entire grip component 400, and analyzes the data through a built-in algorithm to determine the state of holding the grip component 400.
[0061] See Figure 11 As shown, specifically, the grip detection device converts the light intensity change characteristics sampled by itself into an electrical signal, and transmits it to an external data processing unit via wired or wireless means. The data processing unit performs comprehensive analysis and judgment based on the received electrical signal information and in combination with an algorithm, and outputs the final result.
[0062] It is understandable that the means of transportation may be known means of transportation such as motorcycles, cars, airplanes, ships, trains, etc., and may also be new means of transportation that will appear in the future.
[0063] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
