Description

Technical Field

[0001] This utility model relates to the field of seat belt structure technology, specifically to a seat belt buckle, seat, and vehicle. Background Technology

[0002] The seatbelt buckle is a crucial component of a car seatbelt. It locks the seatbelt latch, preventing the seatbelt from slipping off; it also acts as an unlocking switch when the seatbelt needs to be unbuckled. However, in poorly lit conditions such as at night or when driving through tunnels, it can be difficult for occupants to accurately locate the buckle.

[0003] To address this, related technologies employ luminous elements around the seatbelt latch to indicate its location, thereby improving the ease of fastening or unfastening the seatbelt when interior lighting is insufficient. However, these luminous elements only provide basic illumination; while they can indicate the approximate location of the latch, they cause significant light pollution, potentially interfering with the senses of passengers and negatively impacting the driving experience.

[0025] like Figures 1 to 3 As shown, this embodiment provides a seatbelt buckle, including a buckle body 1 and a first light-emitting element 2. The top of the buckle body 1 has a locking hole 111 suitable for the seatbelt latch to be inserted and connected. The first light-emitting element 2 is disposed in the locking hole 111. The outer shell 11 of the buckle body 1 is made of an opaque material so that the light emitted by the first light-emitting element 2 can be transmitted through the locking hole 111. In this way, by arranging the first light-emitting element 2 in the locking hole 111 of the buckle body 1 and configuring the outer shell 11 of the buckle body 1 as an opaque material, the light emitted by the first light-emitting element 2 can only be transmitted through the locking hole 111. This not only serves to indicate the position of the locking hole 111, but also reduces the impact of the light-emitting element on the user's visual perception, thereby improving the user experience.

[0026] Specifically, the first light-emitting element 2 can be an LED light strip, providing ample illumination and durability. The first light-emitting element 2 can be fixed inside the latch body 1 by adhesive or clips, and is positioned below the lock hole 111. It is powered and illuminated by a wire (not shown) connected to a vehicle power supply or its own power source. The outer shell 11 of the latch body 1 can be made of black primer or an opaque material. Thus, the outer shell 11 of the latch body 1 can block the light emitted by the first light-emitting element 2, ensuring that the light emitted by the first light-emitting element 2 can only pass through the lock hole 111.

[0027] It is understood that the buckle body 1 can be a conventional seat belt buckle, which includes a housing 11, a fixing component 12, and a locking component 13 and an unlocking component 14 arranged inside the housing 11. The top of the housing 11 has a lock hole 111. The locking component 13 is located below the lock hole 111 and can lock the seat belt latch when it is inserted into the lock hole 111 to prevent the seat belt from falling off. The unlocking component 14 is located on one side of the lock hole 111 and is linked with the locking component 13. When it is necessary to unfasten the seat belt, the seat belt latch can be released by pressing the unlocking button 141 of the unlocking component 14, thereby unlocking the seat belt. The specific structure and connection relationship of the locking component 13 and the unlocking component 14 are existing technologies and will not be described in detail here.

[0028] Furthermore, such as Figure 2 The exploded view shown illustrates some components of the locking part 13 of the latch body 1. In this embodiment, the locking part 13 of the latch body 1 includes at least a support member 131 that restricts the movement of the seat belt latch tongue along the opening direction of the lock hole 111. A groove 1311 is formed on the side wall of the support member 131. The first light-emitting element 2 is fixed in the groove 1311 by pasting or snapping, thus ensuring that the light emitted by the first light-emitting element 2 can be transmitted through the lock hole 111. In other embodiments, the first light-emitting element 2 can also be disposed at the bottom of the outer casing 11 corresponding to the lock hole 111, or it can be disposed on other parts of the locking part 13, as long as the position of the first light-emitting element 2 corresponds to the lock hole 111 so that the light emitted by it can be transmitted through the lock hole 111.

[0029] In some embodiments, such as Figure 3 As shown, the first luminous element 2 is electrically connected to the vehicle's seatbelt unfastened reminder system 4. The seatbelt unfastened reminder system 4 is configured to illuminate the first luminous element 2 when the seatbelt is detected as unfastened, and to extinguish the first luminous element 2 when the seatbelt is detected as fastened. This serves two purposes: firstly, it indicates the position of the seatbelt latch 111 when the seatbelt is unfastened, solving the problem of difficulty in identifying the seatbelt latch 111 position during nighttime driving; secondly, it saves electricity and avoids unnecessary power consumption.

[0030] Specifically, the seatbelt reminder system is a mandatory safety system in modern vehicles. It uses sensors in conjunction with seat pressure detection to warn and remind drivers and passengers, through audible alarms and dashboard icons, to ensure that they have properly fastened their seatbelts before driving. Figure 3 As shown, in this embodiment, the seatbelt unfastened reminder system 4 includes at least a seatbelt buckle sensor 41 and a control unit 42. The seatbelt buckle sensor 41 can be a micro switch or a magnetic sensor installed inside the buckle body 1 (not shown). It can trigger an electrical signal when the seatbelt latch is inserted and output a disconnect signal when it is not inserted, thereby detecting the connection status between the seatbelt latch and the buckle body 1. The control unit 42 can be a microcontroller and a circuit board installed inside the buckle body 1 (not shown). It is connected to the vehicle power supply, the seatbelt buckle sensor 41 and the first light-emitting element 2 through wires (not shown). It is used to control the first light-emitting element 2 to light up or turn off according to the detection result of the seatbelt buckle sensor 41.

[0031] It is understandable that the seat belt unfastened reminder system 4 can also use a conventional vehicle infotainment system and sensors to detect the connection status between the seat belt latch and the buckle body 1 through the sensors and output corresponding signals to the vehicle infotainment system, which then controls the first light-emitting element 2 to light up or turn off.

[0032] In some embodiments, such as Figures 1 to 3 As shown, the seatbelt buckle also includes a second light-emitting element 3. The second light-emitting element 3 is positioned near the unlocking button 141 on the buckle body 1 and is electrically connected to the seatbelt unfastened reminder system 4. The seatbelt unfastened reminder system 4 is configured to illuminate the second light-emitting element 3 when the seatbelt is detected as fastened, and to extinguish the second light-emitting element 3 when the seatbelt is detected as unfastened. The second light-emitting element 3 provides guidance when the user needs to unfasten the seatbelt, indicating the location of the unlocking button 141, thus facilitating the user's unfastening of the seatbelt.

[0033] Specifically, such as Figure 2 The exploded view shown illustrates some components of the unlocking component 14 of the latch body 1. In this embodiment, the unlocking component 14 of the latch body 1 includes at least an unlocking button 141 arranged side-by-side on one side of the lock hole 111. The second light-emitting element 3 can be an LED light strip, utilizing its malleable shape and high-brightness uniformity to achieve effective adhesion with the unlocking button 141. The second light-emitting element 3 can be fixed to the outer surface of the unlocking button 141 by pasting or snapping, or fixed to the outer shell 11 surrounding the unlocking button 141 by pasting or snapping. Thus, the location of the unlocking button 141 can be indicated by the light emitted by the second light-emitting element 3. It is understood that in this embodiment, the control unit 42 of the aforementioned seatbelt unfastened reminder system 4 can be connected to the second light-emitting element 3 via a wire (not shown), and the second light-emitting element 3 can be controlled to light up or turn off according to the detection result of the seatbelt buckle sensor 41.

[0034] Similarly, the seatbelt reminder system 4 can also use a conventional vehicle infotainment system and sensors to detect the connection status between the seatbelt latch and buckle body 1 through the sensors and output corresponding signals to the vehicle infotainment system, which then controls the second light-emitting element 3 to light up or turn off.

[0035] In this way, through the coordinated operation of the first light-emitting element 2 and the second light-emitting element 3, user needs can be decomposed based on human factors engineering, and the user's required operation can be associated with the corresponding operation object by using light indicators in different positions, which is more in line with the user's usage habits and intuition, and provides more comprehensive visual guidance.

[0036] In some embodiments, the second light-emitting element 3 is arranged around the circumference of the unlock button 141. Specifically, a mounting groove can be arranged around the circumference of the unlock button 141. The mounting groove can be arranged on the unlock button 141 or on the housing 11. The second light-emitting element 3 is embedded and fixed in the mounting groove by adhesive or snap-fit, so as to realize the circumferential fixing of the second light-emitting element 3 around the unlock button 141, thereby accurately and effectively indicating the location of the unlock button 141.

[0037] In some embodiments, the unlock button 141 or at least a portion thereof may be made of a transparent material such as transparent PP / PC through injection molding, thereby giving the unlock button 141 a light-transmitting layer; such as Figure 1 As shown, the second light-emitting element 3 is positioned inside the housing 11 corresponding to the unlocking button 141, so that the light emitted by the second light-emitting element 3 can pass through the light-transmitting layer of the unlocking button 141, thereby accurately and effectively indicating the location of the unlocking button 141. Simultaneously, this arrangement maintains the visual consistency of the unlocking button 141 during periods when the second light-emitting element 3 is not emitting light, resulting in an aesthetically pleasing seatbelt buckle.

[0038] In some embodiments, such as Figure 3 As shown, after the control unit 42 is connected to the second light-emitting element 3, the control unit 42 is configured to control the second light-emitting element 3 to switch from a constant-on mode to a breathing mode after a preset time (e.g., 10 seconds) after detecting that the seat belt is fastened. In this way, the second light-emitting element 3 can display different usage states through different lighting modes, making it easier for users to distinguish them; at the same time, the breathing mode is more energy-efficient than the constant-on mode and can create a good visual decorative effect, creating a dynamic and soft atmosphere and improving the user experience.

[0039] It is understandable that the control unit 42 can realize the timing switching of the light emission mode of the second light-emitting element 3 by configuring functional modules such as PWM (Pulse Width Modulation) dimming module and timer. The specific circuit connection method and control method are existing technologies and will not be described in detail here.

[0040] In summary, the seatbelt buckle provided in this application embodiment can illuminate the first light-emitting element 2 inside the buckle when the seatbelt is not fastened to indicate the position of the lock hole 111; after the seatbelt is fastened, the first light-emitting element 2 is turned off, and the second light-emitting element 3 outside the buckle is illuminated, remaining on for 10 seconds before switching to a breathing light mode to indicate the position of the unlock button 141. This not only serves to indicate the positions of the lock hole 111 and the unlock button 141 in low-light environments but also creates a good visual decorative effect, reduces the power consumption of the light-emitting elements, minimizes the impact of the light-emitting elements on the user's visual senses, and ultimately enhances the user experience.
