[Technical Field]

[0001] This utility model relates to the field of motor vehicle seat belts, and in particular to a seat belt buckle and a motor vehicle. [Background Technology]

[0002] With the increasing number of motor vehicle owners in my country, addressing various safety issues while riding in motor vehicles has become increasingly important, and seat belts are the primary guarantee of user safety. In daily life, driving at night or in low-light conditions is a common scenario. When users need to fasten their seat belts in poor lighting conditions, they often need to turn on the interior lights or blindly fasten the buckle because they cannot clearly see its location. Therefore, seat belt buckles with illuminated buckle positions are now available.

[0003] However, existing seat belt buckles with luminous indicators usually place the LED module and other display structures inside the seat belt buckle, and then achieve the effect of displaying the light by opening the surface of the seat belt buckle to let the light pass through. The display structure under this design occupies a lot of internal structural space of the seat belt buckle, reducing the utilization rate of the internal structural space of the seat belt buckle. Moreover, due to the size limitation of the seat belt buckle itself, it is difficult to integrate more complex display structures. [Utility Model Content]

[0021] 3. The first light emitting module and the second light emitting module of the utility model are arranged at intervals. When the car machine interconnection module controls the first light emitting module and the second light emitting module to display different light effects respectively, the light effects between the two light emitting modules are avoided, thereby preventing the mixed light effects from affecting the visual effect of the user and reducing the occurrence of the guiding and prompting of the seat belt buckle.

[0022] 4. The display module of the utility model is a Micro LED module or a Mini LED module. By adopting the Micro LED module or the Mini LED module as the display module, the display module only occupies a very small part of the lock body structure space, the problem that the traditional LED module is large in size and is difficult to be integrated and installed under the condition that the lock body structure space is limited is optimized, and the structural layout of the display module in the lock body space is effectively optimized.

[0023] 5. The display module of the utility model is a flexible module, the flexible module comprises an FPC circuit board, and the flexible radius of curvature of the flexible module is greater than or equal to 1 mm. On the one hand, by arranging the display module as a flexible module, the display module in a single mounting groove is integrated, so that the gap during display of light is avoided, and the visual effect of the display module is affected; on the other hand, by arranging the flexible radius of curvature range of the flexible module, the flexible module can realize large-angle bending without damage, the display module is prevented from being damaged due to too large bending angle at the corner of the mounting groove, and the light emitting effect and service life of the display module are greatly improved.

[0024] 6. The FPC circuit board is electrically connected with the car machine interconnection module through an FPC flexible flat cable connector or a B TB connector, and supplies power to the display module.

By limiting the width size and thickness size of the display module, the lock body space position occupied by the display module is further reduced, and the lock body structure layout is optimized.

[0026] 8、The groove depth range of the first mounting groove and the second mounting groove is within 0.95mm to 1.05mm. By limiting the smaller groove depth tolerance, the matching precision between the display module and the mounting groove is improved, and the assembly difficulty is reduced.

[0027] 9、The substrate of the first light-emitting module and the substrate of the second light-emitting module are respectively installed parallel to the side wall of the first mounting groove and the side wall of the second mounting groove. By adopting the lateral installation mode to set the display module, the width of light emission is reduced, and the visual adhesion effect between two light-emitting distances is avoided, which causes the display module to be unclearly marked on the plug position.

For ordinary skilled persons in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0043] Please refer to Figure 1 and Figure 2The utility model discloses a first embodiment provides a kind of safety belt insertion buckle 1, including lock body 2, lock body 2 includes socket 21, button 22, display module 23 and the first installation slot 24 being set along the outline of socket 21;Display module 23 includes the first light-emitting module 231 being set around the outline of socket 21, and the first light-emitting module 231 is installed in the first installation slot 24;Safety belt insertion buckle 1 includes lock tongue 3, and the shape of lock tongue 3 corresponds with socket 21;Safety belt insertion buckle 1 further include car machine interconnection module 4, and car machine interconnection module 4 is set in lock body 2, and is connected with the signal of first light-emitting module 231.

[0044] It can be understood that, since the first installation slot 24 is set around the outline of the socket 21, when the first light-emitting module 231 is set in the first installation slot 24, the first light-emitting module 231 is lit around the outline of the socket 21, which facilitates the user to quickly locate the socket 21 and align the lock tongue 3 with the socket 21 for insertion in the case of poor ambient light, and improves the ease of use of the safety belt insertion buckle 1.

[0045] It can be understood that the first installation slot 24 set on the surface of the lock body 2 provides a space for the first light-emitting module 231 to be installed on the shell of the lock body 2, which facilitates the first light-emitting module 231 to be embeddedly integrated on the surface of the lock body 2, i.e., only the car machine interconnection module 4 for controlling the display state of the display module 23 is set in the interior of the lock body 2, which greatly reduces the additional space required by the display module 23 in the interior of the lock body 2, and improves the space structure utilization rate in the interior of the lock body 2.

[0046] Specifically, the shell of the lock body 2 is made of hard material, which further improves the protection of the lock body 2 to the first light-emitting module 231.

[0047] It can be understood that the design of the first light-emitting module 231 embeddedly integrated on the surface of the lock body 2 also effectively avoids physical damage such as collision and scratching of the first light-emitting module 231 from the outside, which improves the service life of the first light-emitting module 231.

[0048] Specifically, the display state of the display module 23 is controlled by the car machine interconnection module 4; in this embodiment, after the car machine interconnection module 4 checks the use state of the safety belt insertion buckle 1 and the state of the motor vehicle, it controls the display module 23 to display different light effects corresponding to different states.

[0049] More specifically, the car machine interconnection module 4 and the first light-emitting module 231 are connected by a wire or wireless signal transmission to realize signal connection; more specifically, when the car machine interconnection module 4 and the first light-emitting module 231 are connected by wireless signal transmission, the display module 23 includes a control module electrically connected with the first light-emitting module 231, and the control module includes a wireless receiving module interconnected with the car machine interconnection module 4.

[0050] Understandably, by detecting and controlling the illumination status of the display module 23 through the vehicle-machine interconnection module 4, when the seat belt buckle 1 is not in operation or malfunctions, the display module 23 provides intelligent light prompts, making it easy for users to quickly obtain the usage status or fault information of the seat belt buckle 1, avoiding potential safety hazards during driving, and reducing unnecessary maintenance costs.

[0051] Furthermore, the lock body 2 surrounds the button 22 or on the surface of the button 22, and a second mounting groove 25 is provided along the outline of the button 22. The display module 23 includes a second light-emitting module 232. The second light-emitting module 232 is installed in the second mounting groove 25, and the vehicle-machine interconnection module 4 is signal connected to the second light-emitting module 232.

[0052] Specifically, in this embodiment, the second mounting groove 25 is formed on the surface of the lock body 2 around the outline of the button 22.

[0053] Understandably, the second light-emitting module 232, located in the second mounting slot 25, highlights the location of the button 22 during illumination, making it easier for users to quickly locate the button 22 and release the connection between the latch 3 and the lock body 2 in poor lighting conditions, thus improving the usability of the seat belt buckle 1.

[0054] Understandably, the setting of the second mounting slot 25 enables the embedded installation of the second light-emitting module 232 on the surface of the lock body 2 or the button 22, and has the same beneficial effect as the embedded installation of the first light-emitting module 231 on the surface of the lock body 2, which will not be elaborated here.

[0055] Furthermore, the first light-emitting module 231 and the second light-emitting module 232 are arranged at intervals.

[0056] Specifically, the vehicle-machine interconnection module 4 independently controls the display state of the first light-emitting module 231 and the second light-emitting module 232; that is, the two light-emitting modules can display different display states at the same time.

[0057] Understandably, the spacing between the first light-emitting module 231 and the second light-emitting module 232 avoids the edges of the two light-emitting areas from overlapping, preventing the light effects emitted by the two modules from mixing when they are too close together, thus affecting the user's visual effect and weakening the light effect guidance and prompting function of the seat belt buckle 1.

[0058] Furthermore, the display module 23 is a Micro LED module or a Mini LED module.

[0059] Specifically, the LED lamp beads used on the display module 23 include single-color lamp beads and three-color RGB lamp beads, and the arrangement mode of the LED lamp beads of the display module 23 is continuous arrangement of single-color lamp beads, arrangement of RGB lamp beads, or interval arrangement of single-color lamp beads and RGB lamp beads.

[0060] It can be understood that the size of the display module 23 affects the space occupied by the first mounting groove 24 and the second mounting groove 25 on the lock body 2, and due to the limitation of the size of the safety belt buckle 1, the profiles of the socket 21 and the button 22 are limited, and a display module 23 with too large a size may cause visual adhesion between two light-emitting distances close to each other; the display module 23 using a Micro LED module or a Mini LED module greatly reduces the size of the display module 23, is easier to assemble in the structure of the lock body 2 with limited space, greatly improves the utilization rate of the space structure of the lock body 2, and at the same time improves the visual effect of the display module 23.

[0061] Specifically, in the embodiment, the display module 23 includes two display states: when the car-machine interconnection module 4 detects that the lock tongue 3 is normally inserted into the lock body 2, the display module 23 is in a green constant-on or off state; when the car-machine interconnection module 4 detects that the lock tongue 3 is not normally inserted into the lock body 2, there is a fault in the lock body 2, or there is a fault in the internal system of the vehicle, the display module 23 is in a red flashing state, and the light intensity or flashing frequency is changed according to different fault states.

[0062] More specifically, the car-machine interconnection module 4 can adjust the display state of the display module 23 through programming control, so as to facilitate the user to adjust the prompt intensity and mode of the display module 23 according to the user's own needs, prevent the prompt intensity of the safety belt buckle 1 from being too low or too high by default after leaving the factory, and limit the prompt effect on the occupant or affect the use experience of the occupant in the motor vehicle.

[0063] Please refer to Figure 2 and Figure 3 Further, the display module 23 is a flexible module, and the flexible module includes an FPC circuit board 233; the flexible radius of curvature of the flexible module is greater than or equal to 1 mm.

[0064] It can be understood that the profiles of the first mounting groove 24 and the second mounting groove 25 are both polygons with large corners, and when the display module 23 is a non-flexible module, a plurality of display modules 23 need to be placed in the mounting grooves for splicing and mounting; the setting of the flexible module 23 facilitates the integrated mounting of the display module 23 in the first mounting groove 24 and the second mounting groove 25, avoids the occurrence of bright and dark bands due to the gaps caused by splicing when the display module 23 displays light, and enhances the visual effect of the display module 23.

[0065] It can be understood that the integrated installation of the display module 23 as a flexible module also eliminates the complex splicing steps, greatly improving the installation simplicity of the display module 23.

[0066] It can be understood that the display module 23 is bent at the corners of the first mounting groove 24 and the second mounting groove 25; when the flexible curvature radius of the flexible module is greater than or equal to 1mm, the chamfer angle bending radius of the display module 23 at the corners around the groove body is greater than 0.5mm, thereby preventing the display module 23 from being damaged due to bending and affecting the working effect of the display module 23.

[0067] Further, the FPC circuit board 233 is electrically connected with the car machine interconnection module 4 through the FPC flexible flat cable connector or the B TB connector, and supplies power to the display module 23.

[0068] It can be understood that the connection mode of the FPC flexible flat cable connector or the B TB connector is suitable for occasions that need to be bent; and compared with the traditional hard connection power supply, the space occupied by the FPC circuit board 233 in the lock body 2 is further saved, and the space structure inside the lock body 2 is optimized.

[0069] Further, the width size of the display module 23 is ≤1mm, and the thickness size is ≤0.4mm.

[0070] It can be understood that the width size and the thickness size of the display module 23 affect the groove volume of the mounting groove and the visual effect of the display module 23; when the width size of the display module 23 is ≤1mm and the thickness size is ≤0.4mm, the display module 23 reduces the structural volume of the lock body 2 occupied without affecting the normal use of the safety belt buckle 1, and improves the visual effect of the display module 23.

[0071] Further, the groove depth of the first mounting groove 24 and the second mounting groove 25 is within the range of 0.95mm to 1.05mm.

[0072] It can be understood that the design of the groove depth of the first mounting groove 24 and the second mounting groove 25 within the range of 0.95mm to 1.05mm limits the tolerance of the groove depth to a smaller range, improves the cooperation precision between the display module 23 and the first mounting groove 24 and the second mounting groove 25, and effectively reduces the assembly difficulty of the lock body 2.

[0073] Further, the substrate of the first light emitting module 231 and the substrate of the second light emitting module 232 are respectively installed parallel to the side wall of the first mounting groove 24 and the side wall of the second mounting groove 25.

[0074] Specifically, the display module 23 emits light on all surfaces except the surface covered by the substrate, that is, the display module 23 is five-surface light emitting.

[0075] It can be understood that when the substrate of the first light-emitting module 231 is installed parallel to the side wall of the first mounting groove 24, the slot of the first mounting groove 24 corresponds to the side of the first light-emitting module 231; when the substrate of the second light-emitting module 232 is installed parallel to the side wall of the second mounting groove 25, the slot of the second mounting groove 25 corresponds to the side of the second light-emitting module 232; the lateral installation of the display module 23 further reduces the light-emitting width of the display module 23, avoiding the visual adhesion effect between two or more light-emitting areas that are close to each other.

[0076] It can be understood that the lateral light-emitting of the display module 23 is beneficial to the scattering of light, so that the light-emitting light efficiency of the display module 23 is more uniform and soft, reducing the distraction of the user during the use of the safety belt buckle 1 due to the glare of the display module 23, greatly reducing the possibility of safety hazards of the user during driving.

[0077] Please refer to Figure 4 , the utility model discloses a motor vehicle 5, including safety belt buckle 1, set up in the lock body 2 far from the lock tongue 3 one end's fixing piece 51, and with the lock tongue 3 is connected with the tape 52.

[0078] Compared with the prior art, the safety belt buckle and the motor vehicle have the following advantages:

[0079] 1、The safety belt buckle includes a lock body, the lock body includes a socket, a button, a display module and a first mounting groove along the contour of the socket; the display module includes a first light-emitting module arranged around the contour of the socket, and the first light-emitting module is installed in the first mounting groove; the safety belt buckle includes a lock tongue, and the shape of the lock tongue corresponds to the socket; the safety belt buckle further includes a car machine interconnection module, which is arranged in the lock body and is signal connected with the first light-emitting module. By opening the first mounting groove along the contour of the socket on the surface of the lock body and installing the first light-emitting module in the first mounting groove, the first light-emitting module is embeddedly integrated on the surface of the lock body, only the car machine interconnection module is arranged in the lock body to control the display module, the space on the surface of the lock body is fully utilized, thereby avoiding the display module from occupying the use space in the lock body, and the utilization rate of the space structure of the lock body is greatly improved.

[0080] 2、The lock body around the button or on the surface of the button body has a second mounting groove along the contour of the button, and the display module includes a second light-emitting module; the second light-emitting module is installed in the second mounting groove, and the car machine interconnection module is signal connected with the second light-emitting module. By arranging the second light-emitting module on the surface of the lock body around the contour of the button or on the surface of the button body, the position of the button is highlighted, so that the user can quickly locate the position of the safety belt unlocking button in the case that the light condition is not good, and the ease of use of the safety belt buckle is improved.

[0081] 3. The first light-emitting module and the second light-emitting module are arranged at intervals. By arranging the two light-emitting modules at intervals, when the car machine interconnection module controls the first light-emitting module and the second light-emitting module to display different light effects, the light effects between the two light-emitting modules are avoided to be mixed, so that the mixed light effects affect the visual effect of the user, and the occurrence of the guiding and prompting effect of the seat belt buckle is reduced.

[0082] 4. The display module is a Micro LED module or a Mini LED module. By adopting the Micro LED module or the Mini LED module as the display module, the display module only occupies a very small part of the lock body structure space, and the problem that the traditional LED module is large in size and difficult to be integrated and installed under the condition that the lock body structure space is limited is solved, and the structure layout of the display module in the lock body space is effectively optimized.

[0083] 5. The display module is a flexible module, and the flexible module comprises an FPC circuit board. The flexible radius of curvature of the flexible module is greater than or equal to 1 mm. On the one hand, by arranging the display module as a flexible module, the display module in a single mounting groove is integrated, and the gap during display is avoided, and the visual effect of the display module is affected. On the other hand, by setting the flexible radius of curvature range of the flexible module, the flexible module can realize large-angle damage-free bending, and the display module is prevented from being damaged due to too large bending angle at the corner of the mounting groove, and the light-emitting effect and service life of the display module are greatly improved.

[0084] 6. The FPC circuit board is electrically connected to the car machine interconnection module through an FPC flexible flat cable connector or a B TB connector, and supplies power to the display module. Compared with the traditional hard connection power supply, the above two connection modes further save the space occupied in the lock body, and optimize the space structure inside the lock body.

[0085] 7. The width size of the display module is ≤1 mm, and the thickness size is ≤0.4 mm. By limiting the width size and thickness size of the display module, the lock body space position occupied by the display module is further reduced, and the lock body structure layout is optimized.

[0086] 8. The slot depth of the first mounting slot and the second mounting slot is within 0.95 mm to 1.05 mm. By limiting the small slot depth tolerance, the cooperation precision between the display module and the mounting slot is improved, and the assembly difficulty is reduced.

[0087] 9. The substrates of the first light-emitting module and the second light-emitting module of this utility model are respectively mounted parallel to the sidewalls of the first mounting groove and the second mounting groove. By adopting a side-mounted mounting method for the display module, the width of the emitted light is reduced, avoiding a visual sticking effect between two light-emitting beams with a small interval, which would otherwise result in unclear markings of the connector position on the display module.

[0088] 10.
