Description

Technical Field

[0001] This utility model relates to a vehicle-mounted illuminated pedal device, specifically a vehicle magnetically sensitive illuminated pedal device using a Hall sensor. The device uses magnetic sensitivity to control the LED module to automatically illuminate when the car door is opened and automatically turn off when the car door is close to closing. Background Technology

[0002] With the rapid development of the automotive industry, consumers have increasingly higher demands for vehicle comfort and convenience. Especially for vehicles with higher body heights, such as SUVs, passengers may experience inconvenience when getting in and out, particularly at night or in low-light conditions, where the door sill location may be unclear, increasing the difficulty and safety hazards of getting in and out. To address this issue, various foot pedal products (also known as "door sill plates") have emerged on the market. These are typically installed at the vehicle door sill to provide additional foot support. Existing door sill plates mainly suffer from the following problems and limitations:

[0003] (1) Insufficient lighting: Many welcome pedals lack lighting, making them inconvenient to use at night or in poor lighting conditions, and making it difficult for passengers to accurately locate the pedals.

[0004] (2) Installation complexity: Some welcome pedals require a complex installation process that may involve modifications to the vehicle body structure. This not only increases installation costs but may also affect vehicle maintenance and safety.

[0005] (3) Aesthetic issues: Some welcome pedals are not aesthetically pleasing and do not match the overall design style of the vehicle, affecting the appearance of the vehicle.

[0006] (4) Durability and reliability: Due to the frequent use of the welcome pedals, they need to withstand greater pressure and wear. Some pedals are not durable and reliable enough, resulting in a short service life.

[0007] Taiwan Patent No. M433989 discloses a wireless illuminated pedal for automobiles. A magnet is installed on the car door. When the car door is closed, the magnet senses the controller located inside the illuminated pedal and cuts off the power, causing the light-emitting module inside the pedal to not emit light. When the car door is opened, the magnet does not power the controller and causes the light-emitting module to emit light.

[0008] However, in order for the magnet and controller to reliably sense when the door is closed, the magnet and controller must be installed precisely in the relevant positions; otherwise, the sensitivity of the sensing will be reduced. This will increase the complexity of the installation process and may involve modifications to the vehicle body structure, increasing installation costs and potentially affecting vehicle maintenance and safety. Utility Model Content

[0009] To overcome the shortcomings of existing technologies, this utility model provides a vehicle magnetically sensitive luminous pedal device using a Hall sensor. This device uses magnetic sensitivity to control an LED module to automatically light up when the car door is opened and automatically turn off when the car door is close to closing, thus solving the problems of existing wireless luminous pedals used in vehicles.

[0010] The aforementioned automotive magnetically sensitive luminous pedal device using Hall sensors includes: a pedal body and a magnet module; wherein, the pedal body is installed on the door sill of a vehicle, and has a circuit board inside, the circuit board having a battery module, an LED driver circuit, an LED module, a logic circuit IC (integrated circuit, chip), and a plurality of Hall effect sensors, wherein the plurality of Hall effect sensors are arranged in a matrix and electrically connected to the logic circuit IC, the logic circuit IC is electrically connected to the LED driver circuit, and the LED driver circuit is electrically connected to the battery module and the LED module; the magnet module is installed below the vehicle door; wherein, the area enclosed by the matrix-arranged plurality of Hall effect sensors constitutes a sensing area; when the vehicle door is opened to a predetermined extent such that any Hall effect sensor in the sensing area fails to sense the magnetic field of the magnet module, the logic circuit IC does not transmit a control signal to the LED. The driving circuit powers the LED module to emit light; when the door is closed to a predetermined extent, causing any of the Hall sensors in the sensing area to sense the magnetic field of the magnet module, a sensing signal is sent to the logic circuit IC. The logic circuit IC then transmits a control signal to the LED driving circuit, which in turn transmits a driving signal to the LED module to de-power it and stop it from emitting light.

[0011] Preferably, in the matrix-distributed Hall sensors, the Hall sensors in two adjacent rows can be staggered, or the Hall sensors in two adjacent columns can be staggered, or the Hall sensors in two adjacent rows and two adjacent columns can be staggered.

[0012] In one specific embodiment, the magnet module includes a housing and a magnet, the magnet being disposed inside the housing. An adhesive element may be provided on the outer surface of the housing for attaching it to the underside of the vehicle door.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] (1) The vehicle magnetic luminous pedal device provided by this utility model integrates a Hall sensor matrix and wireless magnetic sensing technology, which not only provides clear lighting guidance, but also simplifies the installation process and enhances the aesthetics, durability and reliability of the pedal. Through wireless magnetic sensing technology, the luminous pedal with telescopic movement can be synchronized with the opening and closing state of the car door to achieve automatic control and further improve the user experience.

[0015] (2) The magnetic light-emitting pedal device for vehicles of this utility model, through circuit design, forms a matrix network on a two-dimensional plane by arranging multiple Hall sensors at multiple positions on the circuit board. Combined with the unique planar space size of the wireless magnetic pedal, it can sense the entire size of the pedal, thereby greatly improving the sensing sensitivity and accuracy.

[0016] (3) Compared with similar products on the market, the sensing sensitivity of the magnetic light-emitting pedal device for vehicles in this application is greatly improved, and the accuracy requirements for positioning and installation are low, and the power consumption is low. Under the same battery power supply, the standby time of this application is longer, and the power decay after long-term use is less, which can improve the battery life by about 35% compared with the traditional solution.

[0017] (4) Because this application uses a planar Hall sensor matrix for signal capture, it can still maintain good sensitivity after long-term use under complex working conditions after vehicle installation, and the recognition rate of door opening action is high. Attached Figure Description

Detailed Implementation

[0029] To facilitate understanding of the present invention, a detailed description is provided below with reference to the accompanying drawings and embodiments. The drawings show only a portion of the embodiments of the present invention, not all of them. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any effort are within the scope of protection of the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for descriptive purposes only and is not intended to be limiting of the invention.

[0031] See Figure 1 As shown, the automotive magnetically luminous pedal device using a Hall sensor includes a pedal body 11 and a magnet module 12. The pedal body 11 is installed on the vehicle sill 3, and the magnet module 12 is installed below the door 2. When the door 2 is opened, the pedal body 11 is automatically powered on and illuminated to create a visually prestigious welcoming image. When the door 2 is closed, the pedal body 11 is automatically powered off and does not illuminate.

[0032] like Figure 2 As shown, a light-transmitting portion 110 is formed on the upper surface of the pedal body 11. The light-transmitting portion 110 can be text or graphics representing the car brand, or it can be designed into various patterns or designs as needed; a circuit board 111 is provided inside the pedal body 11. Figure 3As shown, the circuit board 111 is electrically connected to a battery module 112, an LED driver circuit 113, an LED module 114, a logic circuit IC 115, and a plurality of Hall sensors 116. The plurality of Hall sensors 116 are arranged in a matrix and electrically connected to the logic circuit IC 115. The logic circuit IC 115 is electrically connected to the LED driver circuit 113, and the LED driver circuit 113 is electrically connected to the battery module 112 and the LED module 114. The matrix arrangement of the Hall sensors 116 can be as follows: Figure 3 , Figure 5 The rows and columns shown are all aligned in a straight line, where the R direction in the figure represents a "column" and the C direction represents a "row"; alternatively, the Hall sensors 116 in adjacent rows can be staggered (e.g., Figure 4 , Figure 6 (as shown); or, the Hall sensors 116 in adjacent columns can be staggered (as shown). Figure 7 (as shown); or the Hall sensors 116 in adjacent rows and adjacent columns can be staggered (as shown). Figure 8 (As shown). The sensing area S is formed by the matrix distribution of a plurality of Hall sensors 116.

[0033] exist Figure 3 In the first embodiment shown, Hall sensors 116 arranged in a matrix with two rows and two columns are used. This configuration is suitable for installing pedal bodies 11 on vehicles with small door sill areas. On some vehicles with larger door sill areas, larger pedal bodies can be installed, thus allowing for the configuration of three or more rows and columns of Hall sensors 116 (e.g., Figures 5 to 8 (As shown). The more Hall sensors 116 arranged in a matrix, the larger the sensing area S formed by their surrounding area, and the more sensitively the magnetic field of the magnet module 12 can be sensed.

[0034] like Figure 9 and Figure 10 As shown, the structure of the magnet module 12 of this application may include: a housing 121 and a magnet 122; wherein, the housing 121 may be made of plastic material, and the magnet 122 is encased inside the housing 121. An adhesive element (such as tape or film with sufficient adhesive strength) may be provided on the outer surface of one side of the housing 121 to adhere the magnet module 12 to the lower part of the car door. The housing 121 may be manufactured by injection molding, and the magnet 122 may be directly encased inside during the manufacturing process; although not shown, the housing 121 may also be separated into two parts, and the magnet 122 may be placed between the two parts before the two parts are joined and fixed together; the joining and fixing may be achieved by various methods such as ultrasonic welding, screw fastening, riveting, adhesive bonding, fastener fastening, etc.

[0035] The LED module 114 is a light-emitting device, generally comprising a light guide plate and a light source (i.e., an LED, not shown in the figure) disposed on the side of the light guide plate. The light guide plate is located inside the pedal body 11 at a position corresponding to the light-transmitting portion 110. When the LED module 114 is powered on and emits light, the light enters the light guide plate for conduction and is finally emitted from the light guide plate to form a light-emitting effect. The light emitted from the light guide plate passes through the light-transmitting portion 110 on the upper surface of the pedal body 11, causing the light-transmitting portion 110 to emit light. Since the LED module is a known light-emitting device and is not the focus of this application, further detailed illustrations and structural descriptions are omitted.

[0036] The battery module 112 may include a battery holder, a battery cover, and a battery. The battery holder is disposed on a circuit board 111. After the battery is placed in the battery holder, it can be electrically connected to the circuit on the circuit board 111 to supply current. The battery cover covers the battery holder and can protect the battery and circuit inside the battery holder. Similarly, the battery module 112 is also a prior art and is not the focus of this application, so more detailed illustrations and structural descriptions are omitted.

[0037] LED driver circuit 113 is a chip (IC) used to drive LED module 114 to emit light. Logic circuit IC 115 is a chip used to receive signals from Hall sensor 116 and then transmit control signals to LED driver circuit 113. When LED driver circuit 113 receives the control signal, it drives LED module 114 to turn off the power and not emit light; conversely, when it stops sending control signals, it powers on the LED module 114 and makes it emit light.

[0038] The magnetically sensitive luminous pedal device of this application is installed and used as follows: the pedal body 11 is installed on the door sill 3 of the vehicle, for example, by adhesive bonding; the magnet module 12 is installed below the door 2. Accordingly, when the door is opened to a predetermined extent, if any Hall sensor 116 in the sensing area S fails to sense the magnetic field of the magnet module 12, the logic circuit IC 115 does not send a control signal to the LED driver circuit 113, and therefore the LED driver circuit 113 controls the LED module 114 to be powered on and emit light. When the door is closed to a predetermined extent, causing any Hall sensor 116 in the sensing area S to sense the magnetic field of the magnet module 12, a sensing signal is sent to the logic circuit IC 115, which then sends a control signal to the LED driver circuit 113, which in turn sends a drive signal to the LED module 114 to control it to be powered off and not emit light.

[0039] The magnetically sensitive light-emitting pedal device of this application has the following advantages compared with similar products on the market:

[0040] (1) The installation is simple, does not involve any changes to the vehicle body structure, will not affect the maintenance and safety of the vehicle, and will not affect the aesthetics of the vehicle. The installation cost is low.

[0041] (2) Since multiple Hall sensors are configured in a matrix manner, the sensing area of ​​the sensing magnetic field can be expanded, thereby reducing the installation accuracy and improving the sensing sensitivity.

[0042] (3) Due to its simple structure, it has good durability and reliability and a long service life.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
