Description

Technical Field

[0001] This utility model relates to the field of automotive control, specifically to a light-sensitive foot kick sensor with projection indication and a vehicle. Background Technology

[0002] The current automatic tailgate switch uses capacitive sensing, employing two capacitive sensors mounted under the bumper as sensing units. When a foot approaches and then moves away simultaneously, a trigger signal is sent to the vehicle's control system. Capacitive sensing has several problems: 1. The leg needs to be close enough to the two capacitive sensors to be detected, but people of different heights may not be able to reach both sensors precisely when kicking; 2. Sensor sensitivity is related to the size of the object being approached; a thinner leg requires a closer proximity; 3. The sensors are close to the rear bumper, and drivers may be reluctant to kick too close for fear of getting their pants dirty, thus preventing triggering; 4. The sensors are installed inside the bumper, making it difficult for the driver to see their location and thus preventing them from kicking at the correct position.

[0003] To address the aforementioned issues, Chinese Patent Application No. 2024202903613 discloses a light-sensitive foot pedal sensor and a vehicle. The light-sensitive foot pedal sensor includes a housing, a distance sensing module, and a projection module. The housing forms a cavity, and a light-transmitting window is provided on the housing. The distance sensing module is disposed within the cavity and includes an encapsulation component, a ranging chip, a lens mount, and a convex lens. The encapsulation component is connected to a circuit board and forms a cavity inside. A through-hole communicating with the cavity is provided on the encapsulation component. The ranging chip is encapsulated within the cavity and faces the through-hole. The lens mount is connected to the circuit board and / or the encapsulation component. The lens mount has a mounting hole communicating with the through-hole and facing the light-transmitting window. The convex lens is disposed on the lens mount and covers the mounting hole. The projection module is disposed within the cavity of the housing, and its projection direction faces the light-transmitting window. The aforementioned light-sensitive foot pedal sensor projects a pattern onto the ground through the projection module and senses whether there is a foot pedal movement by measuring distance using the distance sensing module, thereby sending a tailgate opening / closing signal. Although the addition of a projection module can provide users with an indication of the foot-sensing position, the projection module and the distance sensing module are misaligned, resulting in a non-compact structure, large size, and inconvenient installation. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a light-sensitive foot kick sensor and vehicle with projection indication, so as to solve the problems of existing light-sensitive foot pedal sensors having insufficient compact structure and large size.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A light-sensitive kick sensor with projection indication includes a mounting housing with an internal cavity. A projection indication module and a distance sensor module are housed within the mounting housing. The front face of the mounting housing has a first window for the projection indication module to emit an indication pattern and a second window for the sensor module to emit rays. The projection indication module includes a light panel with LED lights and a projection lens fixedly mounted on the light panel at one end. The fixed end of the projection lens houses the LED light cover, and the front end of the lens corresponds to the first window. When the LED lights are turned on, an indication icon is emitted through the projection lens. The distance sensor module... The sensor module includes a power board and a control main board mounted on the projection lens. The power board is positioned between the lamp board and the control main board, providing power to both. The control main board houses an infrared ranging sensor and a microcontroller. The microcontroller is electrically connected to the infrared ranging sensor, the projection lens, and the LED lights. The infrared ranging sensor corresponds to the second window. A focusing lens is fixed within the second window. The infrared light emitted by the infrared ranging sensor follows the same path as the indicator icon emitted by the projection indicator module, and the infrared light is positioned within the indicator icon's display area. Thus, the projection indicator module and the distance sensor module, upon startup, emit indicator icons and infrared ranging rays in the same direction, with the infrared ranging rays positioned within the indicator icon's area. When in use, the user can perform a foot pedal action within this area according to the indicator icon's indication. This allows the infrared ranging sensor in the distance sensor module to collect the foot pedal action and output the collected distance measurement result to the microcontroller. Finally, the microcontroller outputs the corresponding door opening / closing signal to the door controller based on the distance measurement result, ultimately opening or closing the door. The infrared light emitted by the infrared rangefinder is not easily interfered with by visible light, and the measurement value can determine whether there is a stepping action, resulting in high reliability. The distance sensing module is mounted on the projection lens of the projection indicator module. The lamp board and one end of the projection lens are fixed and secured within the mounting housing, preventing the projection lens from loosening due to shaking. The structure is stable, and the overall layout is reasonable and compact, reducing the overall size of the light-sensitive kick sensor, minimizing its installation space, and facilitating installation layout. The power board, lamp board, and control main board are interconnected. The power board can simultaneously power the lamp board and control main board and connect the control main board and lamp board, resulting in a compact structure. The focusing lens can adjust the 25-degree FOV angle emitted by the infrared rangefinder to approximately 5 degrees.

[0006] Furthermore, a retaining strip is provided on both the left and right sides of the mounting housing, and an adjusting bracket is provided at the front end of the mounting housing to connect with it. The adjusting bracket includes symmetrically arranged adjusting clamps and C-shaped positioning plates connected to the same side of the two adjusting clamps. The C-shaped positioning plates are located near the front end of the mounting housing and have multiple threaded holes spaced apart on them. The adjusting clamps are engaged on the two opposite sides of the mounting housing, and multiple slots that mate with the retaining strips are provided on the inner side of both adjusting clamps. Each slot has a different angle. Thus, during installation, the C-shaped positioning plates of the adjusting bracket are fixedly installed on the bumper or side skirt of the car. After aligning the two sides of the mounting housing with the retaining strips with one of the slots on the two adjusting clamps, the retaining strips are engaged into the slots to position the mounting housing. Since the angle of each slot is different, the final installation angle of the mounting housing will also be different after inserting into different slots, thus achieving adjustment of the angle of the mounting housing. This adjustment method is simple and convenient, with a stable adjustment structure and high operability. It can project the light spot of the pedal pattern obliquely onto the outside of the bumper, making it convenient for the driver to step on. The C-shaped positioning plate has no obstruction in the middle and will not block the first and second windows at the front of the mounting housing.

[0007] Furthermore, the centerline angle of the slot can be any of 0°, 5°, 10°, 15°, 20°, 25°, or 30°. This allows users to select different installation angles according to their needs, thereby adjusting the emission angle of the infrared light from the projection lens and infrared rangefinder within the mounting housing, as well as the position of the emitted light on the ground.

[0008] Furthermore, the control motherboard also includes a Bluetooth chip and / or a LIN chip or a CAN chip, all of which are connected to the control motherboard. This allows the Bluetooth chip to connect with the user's mobile phone via Bluetooth. When the user's phone approaches the car and connects to the Bluetooth chip, the Bluetooth chip sends a signal to the microcontroller, which then controls the projection indicator module and distance sensor module to activate the ranging and projection functions. The LIN or CAN chip connects to the car's remote key. When the user approaches the car to a certain distance, the remote key connects to the LIN or CAN chip, or the car terminal receives a proximity signal from the vehicle's smart key and sends a signal to the microcontroller to activate the projection indicator module and distance sensor module, activating the ranging and projection functions. This structure allows for projection and ranging only after the user is close to a designated location, providing flexibility in use.

[0009] Furthermore, an ambient light sensor connected to the control motherboard is also installed on the control motherboard, and a third window corresponding to the ambient light sensor is located next to the second window. In this way, the ambient light sensor can detect the brightness of the external ambient light of the car through the third window, and when it detects that the ambient light is too dim, it sends the detection result to the control motherboard, which then sends a signal to the LEDs to dim the LEDs on the light panel, so that the indicator pattern projected on the ground is always clear.

[0010] Furthermore, the mounting housing includes a rear cover and a front cover detachably mounted on and sealed to the rear cover. The front cover has a protruding portion in the middle, on which the first window, second window, and third window are located. A hydrophobic glass covering the first, second, and third windows is located at the front end of the protruding portion. Thus, the mounting housing, formed by the sealed connection of the front and rear covers, facilitates the installation of the projection indicator module and the distance sensor module. Simultaneously, the hydrophobic glass mounted on the front cover can guide rainwater or other water, allowing water droplets to flow away quickly to avoid affecting distance measurement.

[0011] Furthermore, the lamp panel is an aluminum substrate, and it is connected to the back cover via thermally conductive silicone grease. Two or three sides of the lamp panel are securely fastened within the back cover, and multiple heat dissipation fins are provided on the outer side of the back cover. In this way, the aluminum substrate has good thermal conductivity. After the lamp panel and the back cover are connected via thermally conductive silicone grease, the generated heat can be transferred to the back cover through the grease. Correspondingly, the heat dissipation fins increase the surface area, achieving rapid heat dissipation and effectively ensuring the normal operation of the projection indicator module.

[0012] Furthermore, a fixing plate is also fitted onto the projection lens, and the fixing plate is detachably connected to the inner wall of the mounting housing. In this way, in addition to being connected to the rear cover via the lamp plate, the projection lens is also fixed to the front or rear cover via the fixing plate, which can effectively ensure the stability of the projection lens installation.

[0013] A vehicle includes a body, a tailgate mounted on the body, and a tailgate drive mechanism kinetically connected to the tailgate. The tailgate drive mechanism is used to drive the tailgate to open or close, and is electrically connected to a control module. The vehicle is characterized by further including a light-sensitive foot-kick sensor as described above. The adjustable bracket of the light-sensitive foot-kick sensor is detachably mounted under the rear bumper or side skirt of the vehicle and is electrically connected to the control module. Thus, the light-sensitive foot-kick sensor is connected to the control module that controls the opening and closing of the tailgate, enabling the sensor to transmit an open or close signal to the control module, which then sends a corresponding signal to the tailgate drive mechanism to control the tailgate to open or close. The light-sensitive foot-kick sensor can be flexibly installed in various positions depending on the vehicle layout; it can be installed on the bumper or under the side skirt. During installation, the C-shaped positioning plate of the adjustable bracket is attached to the rear bumper and secured with fasteners.

[0014] Furthermore, a front hood is provided at the front of the vehicle body, and a hood drive mechanism is also provided on the hood. The hood opening mechanism is used to drive the opening or closing of the front hood, and the hood opening mechanism is electrically connected to the control module. Two light-sensitive foot kick sensors are provided, one of which is detachably mounted on the front bumper of the vehicle. In this way, if it is necessary to add corresponding automatic opening and closing to the front hood, foot-sensing control of the front hood can be achieved by installing light-sensitive foot kick sensors and a hood drive mechanism.

[0018] like Figures 1-5As shown, the light-sensing kick sensor with projection indicator provided in this embodiment includes a mounting housing 1 with an internal cavity. A projection indicator module 2 and a distance sensor module 3 are disposed within the mounting housing 1. A first window for the projection indicator module 2 to emit an indicator pattern and a second window for the sensor module to emit rays are provided on the front end face of the mounting housing 1. The projection indicator module 2 includes a light panel 21 with LED lights and a projection lens 22 fixedly mounted on the light panel 21 at one end. The fixed end of the projection lens 22 houses the LED lampshade, and the front end of the lens corresponds to the first window. When the LED lights are turned on (in this embodiment, a high-power green LED of approximately 2W is used; other colors can be selected in specific implementations), light emitted through the projection lens 22 can be emitted... The distance sensor module 3 includes a power board 31 and a control main board 32, which are sleeved on the projection lens 22. The power board 31 is placed between the lamp board 21 and the control main board 32 to supply power to the lamp board 21 and the control main board 32. The control main board 32 is equipped with an infrared ranging sensor 33 (a 940nm laser ranging chip) and a microcontroller. The microcontroller is electrically connected to the infrared ranging sensor 33, the projection lens 22 and the LED. The infrared ranging sensor 33 corresponds to the second window. A focusing lens is fixed in the second window. The infrared light emitted by the infrared ranging sensor 33 is projected along the same path as the emission path of the indicator icon emitted by the projection indicator module 2, and the infrared light is placed within the display area of ​​the indicator icon. In this way, the projection indicator module 2 and the distance sensor module 3 can emit an indicator icon and an infrared ranging ray respectively in the same direction after startup, with the infrared ranging ray within the area of ​​the indicator icon. Therefore, when using the device, the user can perform a foot pedal action within this area according to the indicator icon. This allows the infrared ranging sensor 33 in the distance sensor module to collect the foot pedal action and output the collected ranging result to the microcontroller. Finally, the microcontroller outputs the corresponding door opening / closing signal to the door controller based on the ranging result, ultimately realizing the opening or closing of the door. The infrared light emitted by the infrared ranging sensor 33 is not easily interfered with by visible light, and the presence of a foot pedal action can be determined by the ranging value, resulting in high reliability. The distance sensor module is mounted on the projection lens 22 of the projection indicator module 2. The light board 21 and one end of the projection lens 22 are fixed and fixed inside the mounting housing 1, preventing the projection lens 22 from becoming loose due to shaking. The structure is stable, and the overall layout is reasonable and compact, reducing the overall size of the light-sensitive foot pedal sensor, minimizing installation space, and facilitating installation layout. The power board 31, the lamp board 21 and the control main board 32 are interconnected. The power board 31 can supply power to both the lamp board 21 and the control main board 32 at the same time, and connects the control main board 32 and the lamp board 21. The structure is compact.

[0019] The projection lens in this embodiment is an externally purchased product, capable of projecting onto the ground at a distance of 30-50cm. Similar to existing projection lenses installed in store advertisements, different patterns can be projected according to user needs.

[0020] Furthermore, a retaining strip 17 is provided on both the left and right sides of the mounting housing 1, and an adjusting bracket 7 connected to it is also provided at the front end of the mounting housing 1. The adjusting bracket 7 includes symmetrically arranged adjusting clamps 72 and C-shaped positioning plates 71 connected to the same side of the two adjusting clamps 72. The C-shaped positioning plates 71 are located near the front end of the mounting housing 1, and multiple threaded holes 73 are provided at intervals on the C-shaped positioning plates 71. The adjusting clamps 72 are clamped on the two opposite sides of the mounting housing 1, and multiple slots 75 that cooperate with the retaining strips 17 are provided on the inner side of the two adjusting clamps 72. The angle of each slot 75 is different. The end of the two adjusting clamps 72 away from the C-shaped positioning plates 71 is also provided with a through hole. After the two clamps are bolted through the through hole, they are further fixed to the mounting housing 1. During installation, the C-shaped positioning plate 71 of the adjusting bracket 7 is fixedly installed on the car's bumper or side skirt. The two sides of the mounting housing 1 with the retaining strip 17 are aligned with one of the slots 75 on the two adjusting clamps 72. The retaining strip 17 is then inserted into the slot 75 to position the mounting housing 1. Since each slot 75 has a different angle, inserting it into different slots 75 will result in different final installation angles for the mounting housing 1, thus adjusting the angle of the mounting housing 1. This adjustment method is simple, convenient, and the adjustment structure is stable and highly operable. It can project the light spot of the step pattern obliquely onto the outside of the bumper, making it convenient for the driver to step on. The C-shaped positioning plate 71 has no obstruction in the middle and will not block the first and second windows at the front of the mounting housing 1.

[0021] Furthermore, the centerline angle of the slot 75 is any two or more of 0°, 5°, 10°, 15°, 20°, 25°, and 30°. This allows users to select different installation angles according to their needs, thereby adjusting the emission angle of the infrared light from the projection lens 22 and the infrared rangefinder 33 within the mounting housing 1, as well as the position of the emitted light on the ground.

[0022] Furthermore, the control motherboard 32 is also equipped with a Bluetooth chip and / or a LIN chip or a CAN chip, all of which are connected to the control motherboard 32. In this way, the Bluetooth chip can connect to the user's mobile phone via Bluetooth. When the user's mobile phone approaches the car and connects to the Bluetooth chip, the Bluetooth chip sends a signal to the microcontroller, which then controls the projection indicator module 2 and the distance sensor module 3 to start, activating the distance measurement and projection functions. The LIN chip or CAN chip can connect to the car's remote key. When the user approaches the car to a certain distance, the remote key connects to the LIN chip or CAN chip, or the car terminal receives a smart key proximity signal from the vehicle and sends a signal to the microcontroller, controlling the projection indicator module 2 and the distance sensor module 3 to start, activating the distance measurement and projection functions. This structure allows for projection and distance measurement only after the user is close to the designated location, providing flexibility in use.

[0023] Furthermore, an ambient light sensor connected to the control motherboard 32 is also provided on the control motherboard 32, and a third window corresponding to the ambient light sensor is provided next to the second window. In this way, the ambient light sensor can detect the brightness of the ambient light outside the car through the third window, and when it detects that the ambient light is too dim, it sends the detection result to the control motherboard 32, which then sends a signal to the LED to reduce the brightness of the LED on the light panel 21, so that the indicator pattern projected on the ground is always clear.

[0024] Furthermore, the mounting housing 1 includes a rear cover 11 and a front cover 12 (both the front cover 12 and the rear cover 11 are made of aluminum alloy) that is detachably mounted on and sealed to the rear cover 11. The front cover 12 has an outward protrusion 16 in the middle, on which the first window, the second window, and the third window are located. The outer edge of the outward protrusion 16 extends outward to form a water-blocking ring. A hydrophobic glass 6 that completely covers the first window, the second window, and the third window is embedded in the water-blocking ring. The outer edge of the hydrophobic glass 6 is bonded to the water-blocking ring with sealant to provide waterproofing. In this way, the mounting housing 1 is formed by the sealed connection of the front cover 12 and the rear cover 11, which facilitates the installation of the projection indicator module 2 and the distance sensor module 3. At the same time, the hydrophobic glass 6 installed on the front cover 12 can guide rainwater or other water, allowing water droplets to flow away quickly to avoid affecting the distance measurement.

[0025] like Figure 1As shown, four internally threaded protrusions 13 are provided on the outer side of the rear cover 11, and four mounting holes 14 corresponding to the internally threaded protrusions 13 are provided on the outer side of the front cover 12. The front cover 12 and the rear cover 11 are connected and fixed to the internally threaded protrusions 13 by bolts passing through the mounting holes 14. A frame-shaped mounting groove 15 is also provided on the inner side of the rear cover 11, and a frame-shaped protrusion corresponding to the frame-shaped mounting groove 15 is provided on the side edge of the front cover 12. The frame-shaped protrusion is stuck in the frame-shaped mounting groove 15, and a frame-shaped sealing ring 16 is also provided in the frame-shaped mounting groove 15. This connection method is a sealed connection through a double connection of clamping positioning and bolt fixing. The connection structure is stable and has good sealing performance, and it also prevents external stains or rainwater from entering the mounting housing 1.

[0026] Furthermore, the lamp panel 21 is an aluminum substrate, and the lamp panel 21 is connected to the back cover 11 via thermally conductive silicone grease. Two opposite sides, three adjacent sides, or four sides of the lamp panel 21 are all clamped and fixed inside the back cover 11 (a protrusion is provided on the inner side of the back cover 11, and a groove corresponding to the protrusion is provided on three sides of the aluminum substrate, and the groove on the aluminum substrate is clamped and fixed to the protrusion). Multiple heat dissipation fins are provided on the outer side of the back cover 11. In this way, the aluminum substrate has good thermal conductivity. After the lamp panel 21 and the back cover 11 are connected by thermally conductive silicone grease, the generated heat can be transferred to the back cover 11 through the thermally conductive silicone grease. Corresponding to the heat dissipation fins, the heat dissipation fins increase the outer surface area to achieve rapid heat dissipation, effectively ensuring the normal use of the projection indicator module 2.

[0027] Furthermore, a fixing plate 23 is also fitted onto the projection lens 22, and the fixing plate 23 is detachably connected to the inner wall of the mounting housing 1. Specifically, the fixing plate 23 is connected and fixed to the mounting housing 1 by fasteners. In this way, in addition to being connected to the rear cover 11 through the lamp plate 21, the projection lens 22 is also fixed to the front cover 12 or the rear cover 11 through the fixing plate 23, which can effectively ensure the stability of the projection lens 22 installation.

[0028] In this embodiment, the power board 31 has at least one positioning hole, and a threaded blind hole corresponding to the positioning hole is provided on the inner side of the front cover 12. After the power board 31 passes through the positioning hole with a positioning bolt, it is threadedly engaged with the threaded blind hole on the front cover 12. The pin header provided on the power board 31 corresponds to the interface on the side of the front cover 12 and is used to connect to the vehicle's power supply for power supply. The control main board 32 also has at least one fixing hole, and a threaded blind hole corresponding to the fixing hole is provided inside the front cover 12. After the control main board 32 passes through the fixing hole with a screw, it is threadedly engaged with the threaded blind hole. Example

[0029] The vehicle provided in this embodiment includes a vehicle body, a tailgate mounted on the vehicle body, a tailgate drive mechanism connected to the tailgate, and a light-sensitive kick sensor. The tailgate drive mechanism is used to drive the tailgate to open or close, and the tailgate drive mechanism is electrically connected to a control module; the light-sensitive kick sensor is as described in Embodiment 1, such as... Figure 6 As shown, the adjusting bracket 7 of the light-sensitive foot kick sensor is detachably installed under the rear bumper of the vehicle (in a specific implementation, it can also be installed on the side skirt of the vehicle body) and electrically connected to the control module. In this way, the light-sensitive foot kick sensor is connected to the control module that controls the opening and closing of the tailgate, so that after the light-sensitive foot kick sensor sends an open or close signal, the signal is transmitted to the control module, which then sends a corresponding signal to the tailgate drive mechanism to control the tailgate to open or close. The installation position of the light-sensitive foot kick sensor is flexible and can be varied depending on the vehicle layout; it can be installed on the bumper or under the side skirt of the vehicle body. During installation, the C-shaped positioning plate 71 of the adjusting bracket 7 is attached to the rear bumper of the vehicle and fixed with fasteners.

[0030] In practical implementation, if automatic control of the car's front hood is required, a front hood is also provided at the front of the vehicle body. An hood drive mechanism is also provided on the hood. This hood opening mechanism is used to drive the opening or closing of the front hood, and it is electrically connected to the control module. Two light-sensitive foot kick sensors are provided, one of which is detachably mounted on the front bumper. Thus, if automatic opening and closing of the front hood is also required, foot-sensing control of the hood can be achieved by installing a light-sensitive foot kick sensor and a hood drive mechanism.

[0031] Of course, in practice, the light-sensitive foot-kick sensor can also be installed on the lower side skirt of the car's sliding door as needed, so as to connect with the sliding door drive mechanism and achieve the purpose of foot-kick control of the opening and closing of the sliding door.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
