Description

Technical Field

[0001] The present application belongs to the field of vehicle technology, and specifically relates to a luminous buckle, a seat belt assembly and a vehicle. Background Art

[0002] With the popularization of vehicles, vehicle safety is receiving more and more attention from users.

[0003] In the existing technology, the seat belt assembly, as one of the important components of the vehicle's passive restraint system, can effectively fix the occupant inside the seat by relying on the combination of the lock tongue and the luminous buckle. By pressing the unlocking device on the luminous buckle to release the lock tongue, the occupant can be freed from the seat.

[0004] However, due to the limitations of the arrangement of components within the illuminative luminous belt buckle, the luminous belt buckles currently available on the market are relatively large in size, occupying more space within the vehicle, which goes against the development trend of miniaturized components. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a luminous buckle, a seat belt assembly and a vehicle, which can solve at least part of the above-mentioned problems.

[0006] In order to solve the above technical problems, this application is implemented as follows:

[0008] In an embodiment of the present application, the housing is formed with a housing cavity. The housing cavity is configured to accommodate components disposed within the housing, such as different light sources and two control boards disposed within the housing cavity.

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0031] The luminous buckle, seat belt assembly and vehicle provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0032] See also Figures 1 to 5 An embodiment of the present application provides a luminous buckle, comprising: a shell 10, the shell 10 having a accommodating cavity; two control boards 20, the two control boards 20 are arranged in the accommodating cavity at intervals along a first direction, and the two control boards 20 are both connected to the shell 10, and the two control boards 20 are respectively used to control different light sources in the luminous buckle.

[0033] In the embodiment of the present application, the housing 10 is formed with a housing cavity. The housing cavity is configured to provide space for components disposed within the housing 10, such as different light sources and two control boards 20 disposed within the housing cavity. The control boards 20 are provided to both provide a mounting location for the light sources and to control them. Furthermore, the two control boards 20 enable separate control of the different light sources. Compared to using a single control board 20 to control different light sources, in the present application, two control boards 20 are used to control the different light sources separately. Furthermore, the two control boards 20 can be disposed on either side of the housing 10 along the first direction X, i.e., along the width of the light-emitting buckle. Compared to using a single control board 20 to control different light sources separately, which would require a single control board 20 to span the areas where the different light sources are located, resulting in a large area for the control board 20 and occupying excessive space within the housing cavity, the above configuration reduces the area of the single control board 20, thereby reducing the space occupied by the control board 20 within the housing cavity, thus having the beneficial effect of reducing the volume of the housing 10.

[0034] Optionally, in an embodiment of the present application, the shell 10 includes a first side wall 11, a top wall 15, a second side wall 12 and a bottom wall 16 connected end to end in sequence, the top wall 15 and the bottom wall 16 are arranged opposite to each other along the second direction, and the first side wall 11 and the second side wall 12 are arranged opposite to each other along the first direction; the distance between the top wall 15 and the bottom wall 16 is A, and the distance between the first side wall 11 and the second side wall 12 is B, where A<B; a control board 20 is arranged close to the first side wall 11, and the other control board 20 is arranged close to the second side wall 12.

[0035] Furthermore, the two control boards 20 are arranged opposite to each other along the first direction.

[0036] In the embodiment of the present application, the top wall 15 and the bottom wall 16 are the walls of the housing 10 with the larger area, and the first side wall 11 and the second side wall 12 are the walls of the housing 10 with the smaller area. In actual applications, the housing 10 can be approximately rectangular, and the first and second side walls 11, 12 with the smaller area are narrow walls. Furthermore, the distance between the top wall 15 and the bottom wall 16 is the thickness of the housing 10, and the distance between the first and second side walls 11, 12 is the width of the housing 10. One control board 20 is disposed near the first side wall 11, and the other control board 20 is disposed near the second side wall 12. Furthermore, the two control boards 20 are also disposed relative to each other along the first direction X (i.e., the width direction of the housing 10). It can be understood that the two control boards 20 are parallel to the first side wall 11 or the second side wall 12, respectively. In actual applications, compared with the parallel arrangement of the control panel 20 and the top wall 15 or the bottom wall 16, the design of the control panel 20 being parallel to the first side wall 11 or the second side wall 12 can effectively reduce the volume occupied by the control panel 20 in the plane of the first direction X and the third direction Z in the accommodating cavity. Instead, the control panel 20 is cleverly arranged at a position close to the first side wall 11 or the second side wall 12. Compared with the control panel 20 spanning the accommodating cavity along the first direction X, the above arrangement has the beneficial effect of reducing the volume of the shell 10 while keeping other components in the luminous buckle unchanged.

[0037] Optionally, in the embodiment of the present application, along the first direction, the thickness of the control board 20 is m, wherein 2.5%≤m / B≤5%.

[0038] Furthermore, 1.3mm≤m≤2.2mm, 44mm≤B≤51mm.

[0039] In the embodiment of the present application, along the first direction, the control board 20 occupies a proportion of the accommodating cavity greater than or equal to 2.5% and less than or equal to 5%. In actual application, there are two control boards 20 in the accommodating cavity, that is, along the first direction, the two control boards 20 occupy a proportion of the accommodating cavity greater than or equal to 3% and less than or equal to 10%. The above arrangement can ensure that the control board 20 occupies no more than one-tenth of the space in the accommodating space along the first direction. Compared to the prior art, the embodiment of the present application effectively reduces the space occupied by the control board 20 in the accommodating cavity along the first direction, has the potential to reduce the thickness of the housing 10 along the first direction, and thus has the beneficial effect of potentially reducing the volume of the housing 10.

[0040] Furthermore, the thickness of the control board 20 can be 1.3mm, 1.45mm, 1.76mm, ... 2.0mm, 2.15mm, 2.2mm. Correspondingly, the width of the luminous buckle can be 44mm, 44.6mm, 45.0mm, ... 47.0mm, 48.1mm, 49.5mm, 51mm. This embodiment does not impose any limitation on the specific values.

[0041] Optionally, in the embodiment of the present application, along the second direction, the width of the control board 20 is n, wherein 20%≤n / A≤37.1%.

[0042] Furthermore, 6.8mm≤n≤10mm, 27mm≤A≤34mm.

[0043] In an embodiment of the present application, along the second direction, the proportion of the control board 20 in the accommodating cavity is greater than or equal to 20% and less than or equal to 37.1%. The above setting can achieve that the space occupied by the control board 20 in the accommodating space along the first direction is not greater than 37.1%. Compared with the prior art, the embodiment of the present application effectively reduces the space occupied by the control board 20 in the accommodating cavity along the second direction, and has the possibility of reducing the thickness of the shell 10 along the second direction, and thus has the beneficial effect of achieving the possibility of reducing the volume of the shell 10.

[0044] Furthermore, the thickness of the control board 20 can be 6.8mm, 7.2mm, 8.6mm, ... 9.0mm, 9.8mm, or 10mm. Correspondingly, the width of the luminous buckle can be 27mm, 27.5mm, 28.0mm, 28.9mm, 29mm, ... 31.0mm, 32.6mm, 33.4mm, or 34mm. This embodiment does not impose any limitation on the specific values.

[0045] Optionally, in the embodiment of the present application, along the third direction, the length of the control panel 20 is t, and the length of the luminous buckle is T, wherein 24.2%≤t / T≤27.9%.

[0046] Furthermore, 16mm≤t≤17mm, 61mm≤T≤66mm.

[0047] In an embodiment of the present application, along the third direction, the proportion of the control board 20 in the accommodating cavity is greater than or equal to 24.5% and less than or equal to 27.9%. The above setting can achieve that the space occupied by the control board 20 in the accommodating space along the first direction is not greater than 27.9%. Compared with the prior art, the embodiment of the present application effectively reduces the space occupied by the control board 20 in the accommodating cavity along the third direction, and has the possibility of reducing the length of the shell 10 along the third direction, and thus has the beneficial effect of achieving the possibility of reducing the volume of the shell 10.

[0048] Furthermore, the thickness of the control board 20 can be 16 mm, 16.2 mm, 16.8 mm, 16.9 mm, or 170 mm. Correspondingly, the width of the luminous buckle can be 61 mm, 61.3 mm, 61.8 mm, 61.9 mm, 62 mm, 63.6 mm, 64.1 mm, 65.0 mm, or 66.0 mm. This embodiment does not impose any limitation on the specific values.

[0049] Optionally, in the embodiment of the present application, the housing 10 is provided with an opening 13 , the opening 13 is communicated with the accommodating cavity, and the two control panels 20 are both arranged near the opening 13 .

[0050] In the embodiment of the present application, the opening 13 is provided to provide a passage for a locking tongue compatible with the luminous buckle to be inserted into the accommodating cavity. The locking tongue is inserted into or removed from the accommodating cavity through the opening 13 to connect or disconnect the luminous buckle and the locking tongue. In actual use, the opening 13 is necessary to achieve the matching between the luminous buckle and the locking tongue. The placement of the control panel 20 close to the opening 13 improves the compactness between the opening 13 and the control panel 13, thereby reducing the length of the luminous buckle.

[0051] Optionally, in an embodiment of the present application, the shell 10 further includes at least two support ribs 14, and the two support ribs 14 respectively form limiting grooves with the first side wall 11 and the second side wall 12, and the two control panels 20 are respectively inserted into the limiting grooves 30, and both control panels 20 can be respectively inserted into the limiting grooves 30.

[0052] In an embodiment of the present application, the support ribs 14 are respectively connected to the first side wall 11 and the second side wall 12, and the support ribs 14 form a limiting groove 30 with the first side wall 11 and the second side wall 12 respectively. The limiting groove 30 is set to limit the control panel 20. In actual application, the control panel 20 is inserted into the limiting groove 30 to limit the control panel 20. There is no need to set up a connecting part to limit the control panel 20. It has the beneficial effect of reducing the components in the accommodating cavity and thus saving space in the accommodating cavity. It also has the beneficial effect of preventing the control panel 20 from moving during the use of the seat belt buckle and causing damage to components.

[0053] Optionally, in the embodiment of the present application, the luminous buckle further includes a wiring harness 70 , which is connected between the two control boards 20 .

[0054] In the embodiment of the present application, the wiring harness 70 is provided to realize the electrical connection between the two control boards 20. In addition, part of the wiring harness 70 is also clamped in the limiting groove 30. On the one hand, it reduces the space occupied by the wiring harness 70 in the accommodating cavity. On the other hand, the limiting groove 30 can also limit the wiring harness 70, fix the wiring harness 70, and avoid the movement of the wiring harness 70 during use.

[0055] Optionally, in an embodiment of the present application, the luminous buckle also includes a first light source 40 and a second light source 50 arranged in the accommodating cavity, one of the first light source 40 and the second light source 50 is connected to one of the control boards 20, and the other of the first light source 40 and the second light source 50 is connected to the other control board 20.

[0056] In the embodiment of the present application, the first light source 40 and the second light source 50 are configured to emit light, and the light emitted by the first light source 40 and the second light source 50 can be observed by the user through the housing 10, making it convenient for the user to use the device in a dark environment or when visibility is poor. By providing two control panels 20, the first light source 40 and the second light source 50 can be controlled separately. Moreover, compared to providing a single control panel 20 to control the first light source 40 and the second light source 50, in the present application, the first control panel 20 and the second control panel 20 are respectively provided near the first side wall 11 and the second side wall 12, thereby avoiding the problem of providing a large area of the control panel 20 in the accommodating cavity in order to connect with the first light source 40 and the second light source 50 provided on both sides, thereby occupying a large area of the space in the accommodating cavity and causing the housing 10 to be larger in size. This has the beneficial effect of reducing the size of the housing 10.

[0057] It should be noted that the first light source 40 and the second light source 50 may be LEDs. LEDs have a simple structure, low cost, and stable light output. The color of the light emitted by the first light source 40 and the second light source 50 may or may not be the same, and this embodiment does not impose any limitation on this. For example, the first light source 40 may use a warm white LED, and the second light source 50 may use a blue LED.

[0058] Furthermore, when the first light source 40 and the second light source 50 emit light, the light is emitted in all directions, and the distance between the first light source 40 and the second light source 50 is within the radiation range of the light emitted by the first light source 40 and the radiation range of the light emitted by the second light source 50. It can be understood that the farther the distance, the weaker the brightness of the light. The distance between the first light source 40 and the second light source 50 is the superposition of the light of the first light source 40 and the light of the second light source 50, and the distance between the first light source 40 and the first side wall 11 is only the radiation range of the light emitted by the first light source 40 (there is also a certain amount of light emitted by the second light source 50, but the brightness can be ignored), and the distance between the first light source 40 and the second side wall 12 is only the radiation range of the light emitted by the second light source 50 (there is also a certain amount of light emitted by the first light source 40, but the brightness can be ignored). That is to say, the light emitted by the first light source 40 and the light emitted by the second light source 50 are emitted from different directions, which compensates for the situation that the light intensity of the light emitted by the first light source 40 and the second light source 50 gradually weakens and the brightness decreases after propagating far in the shell 10, thereby greatly increasing the brightness and uniformity of the light in the shell 10, so that the light emitted from the light-transmitting area of the shell 10 is more uniform and bright, and the overall lighting is more ideal and beautiful.

[0059] Therefore, the interval between the first light source 40 and the second light source 50 is greater than the interval between the first light source 40 and the first side wall 11, and the setting that the interval between the first light source 40 and the second light source 50 is greater than the interval between the second light source 50 and the second side wall 12 has the beneficial effect of uniformly emitting brightness from the light source.

[0060] Optionally, in an embodiment of the present application, the luminous buckle further includes a light guide 60, which is disposed in the accommodating cavity and is used to evenly distribute the light emitted by the first light source 40 and the second light source 50; the shell 10 has a light-transmitting area near the opening 13 of the shell 10, and the light emitted by the first light source 40 and the second light source 50 is transmitted through the light guide 60 and then passes through the shell 10 from the light-transmitting area.

[0061] In the embodiment of the present application, in actual application, the light emitted by the first light source 40 and the second light source 50 is symmetrically incident from two different spaced parts of the light guide 60 and converges in the middle of the light guide 60, so that the light of the first light source 40 propagates a shorter distance toward the first side wall 11 and a longer distance toward the second light source 50, while the light of the second light source 50 propagates a shorter distance toward the second side wall 12 and a longer distance toward the first light source 40. Therefore, they compensate for the situation that the light intensity of the light emitted by the first light source 40 and the second light source 50 gradually weakens and the brightness decreases after propagating a longer distance in the light guide 60, thereby greatly increasing the brightness and uniformity of the light in the light guide 60, so that the light transmitted through the light guide 60 in the light-transmitting area is more uniform and bright, and the overall lighting is more ideal and beautiful.

[0062] Optionally, in the embodiment of the present application, a surface of the light guide 60 facing the light-transmitting area is provided with a spark pattern 63 , and the spark pattern 63 is evenly distributed.

[0063] In the embodiment of the present application, providing the spark pattern 63 on the light guide 60 is a special surface treatment technology, which is usually used to improve optical performance or enhance aesthetics. Specifically, the spark pattern 63 can be processed on the light guide 60 by methods such as electric spark machining, laser machining, mold forming, and chemical etching. Specifically, different processing methods can be selected according to the different materials of the light guide 60. The surface of the side of the light guide 60 facing the light-transmitting area can be completely provided with the spark pattern 63, or partially provided with the spark pattern 63, or multiple spark patterns 63 can be provided, and adjacent spark patterns 63 are evenly spaced. The specific setting position can be determined according to actual conditions, and this embodiment does not impose any restrictions on this.

[0064] Furthermore, electrospark machining (EDM) technology is used to create tiny pits on the surface of the light guide 60, forming a spark pattern 63. By adjusting discharge parameters (such as current, voltage, and pulse frequency), the density, depth, and uniformity of the spark pattern 63 can be controlled. Lasers are used to etch tiny textures on the surface of the light guide 60, simulating the effect of the spark pattern 63. Laser machining offers high precision and is suitable for the design of complex patterns. Spark pattern 63 can be machined on the surface of the injection mold for the light guide 60, allowing the texture of the spark pattern 63 to be directly replicated during molding. This method is suitable for mass production. Chemical etching can also be used to form the spark pattern 63 on the surface of the light guide 60. This method is suitable for light guides 60 made of certain special materials or with complex shapes.

[0065] Furthermore, evenly arranging the spark pattern 63 on the light guide 60 can disrupt the propagation path of the light emitted by the first light source 40 and the light emitted by the second light source 50, so that the light is more evenly diffused inside the light guide 60, reducing hot spots and dark areas. This is very important for the luminous buckle to achieve backlight display and lighting functions. The spark pattern 63 can also give the light guide 60 a unique surface texture, enhance the appearance of the product, and increase its visual appeal. The spark pattern 63 can also scatter light, reduce the glare caused by direct reflection of the light emitted by the first light source 40 and the light emitted by the second light source 50, and improve visual comfort. By optimizing the design of the spark pattern 63, the light extraction efficiency of the light guide 60 can be improved, light loss can be reduced, and it can also help achieve uniform light distribution and enhance the user experience.

[0066] It should be noted that a plurality of protrusions 61 are provided on the surface of the side of the light guide 60 that is away from the light transmission area, and the plurality of protrusions 61 are arranged in sequence along the direction from one end of the light guide 60 to the other end. The provision of the plurality of protrusions 61 is used to guide the light emitted by the first light source 40 and the light emitted by the second light source 50 in the direction of reflection, so that the light in the light guide 60 is more uniform. For example, a continuous sawtooth-shaped protrusion 61 can be provided, or a plurality of arc-shaped protrusions 61 can be provided, and the protrusions 61 are arranged in sequence along the direction from one end of the light guide 60 to the other end. Specifically, the protrusions 61 can be formed as arc-shaped protrusions 61. The arc-shaped protrusions 61 make it easier for the light to be dispersed at various angles, thereby improving the uniformity of the light in the light guide 60 to a certain extent.

[0067] It should also be noted that a groove 62 is formed on the side of the light guide 60 facing away from the light transmission area, and a plurality of protrusions 61 are formed on the bottom wall 16 of the groove 62. The provision of the groove 62 is achieved by machining the protrusions 61 inwardly from the outer surface of the light guide 60, thereby eliminating the need to process more surface area, which has the beneficial effect of reducing the loss of the light guide 60 and saving costs. Specifically, the bottom wall 16 of the groove 62 can be formed with a plurality of protrusions 61, and the plurality of protrusions 61 are arranged in sequence in the extension direction of the groove 62. The provision of a plurality of protrusions 61 on one side of the light guide 60 helps to guide the reflection direction of light within the light guide 60, making the light within the light guide 60 more uniform. For example, a groove 62 can be provided on the surface of the light guide 60 facing away from the light transmission area, and a continuous sawtooth-shaped protrusion 61 can be provided in the groove 62, or a circular arc-shaped protrusion 61 can be provided, which makes it easier for the light to be dispersed at various angles, thereby improving the uniformity of the light in the light guide 60 to a certain extent.

[0068] In a second aspect, an embodiment of the present application further provides a seat belt assembly, comprising the aforementioned luminous buckle.

[0069] In the embodiment of the present application, the seat belt assembly includes the luminous buckle as described above, and further includes all the structural features and beneficial effects of the luminous buckle, which will not be repeated here.

[0070] Furthermore, the illuminated buckle is a crucial component of the seatbelt assembly, working in conjunction with the webbing, buckle, pretensioner, and force limiter. The illuminated buckle controls the extension and retraction of the seatbelt using a reel and locking mechanism, ensuring the belt length automatically adjusts to the occupant's needs. The illuminated buckle winds the webbing around the reel, allowing for smooth extension and retraction. In an emergency, the locking mechanism of the illuminated buckle locks the webbing, preventing further extension and thereby restraining the occupant. The pretensioner is typically integrated with the retractor to rapidly tighten the webbing in a collision, reducing the occupant's forward movement. Under normal driving conditions, the retractor allows the webbing to freely extend and retract, making it easier for the occupant to fasten the seatbelt and adjust their comfort. During rapid acceleration, deceleration, or cornering, the retractor's locking mechanism activates to prevent excessive webbing extension. At the moment of a collision, the retractor's locking mechanism instantly locks, preventing further webbing extension. The pretensioner rapidly tightens the seatbelt, securing the occupant in the seat and reducing forward movement. The force limiter restrains the occupant while preventing excessive chest pressure from the seatbelt. When the vehicle brakes suddenly, the retractor's locking mechanism activates, preventing the occupant from moving forward due to inertia. This locking function prevents the seatbelt from suddenly slacking when driving on bumpy roads or off-road, ensuring occupant safety.

[0071] In a third aspect, an embodiment of the present application further provides a vehicle comprising the aforementioned seat belt assembly.

[0072] In the embodiment of the present application, the vehicle includes the seat belt assembly as described above, and further includes all the structural features and beneficial effects of the seat belt assembly, which will not be repeated here.

[0073] Furthermore, the seatbelt assembly is designed to ensure effective occupant protection in various driving scenarios. Its primary functions include automatic retraction, locking, and pretensioning, playing a vital role in enhancing vehicle safety during daily driving, emergency braking, and collisions.
