Description

Technical Field

[0001] This utility model relates to the field of traffic safety equipment, and in particular to a seat belt alarm device. Background Technology

[0002] In the field of automotive safety, seat belts are crucial devices for protecting the lives of drivers and passengers. With the continuous increase in vehicle speeds and the frequency of traffic accidents, the requirements for the reliability and intelligence of seat belt alarm devices are becoming increasingly stringent. Existing seat belt alarm devices mostly use a simple plug-and-play detection method, only able to determine whether the seat belt is inserted into the buckle, which has many shortcomings. On the one hand, they cannot detect the actual tightness of the seat belt; if the seat belt is too loose, it will be difficult to effectively restrain the occupants in a collision. On the other hand, some devices lack multi-position synchronous monitoring capabilities, and the status of the rear or front passenger seat belts cannot be reported in a timely manner. Furthermore, traditional devices have poor structural stability, and are prone to false alarms or missed alarms with long-term use. Therefore, developing an alarm device that can accurately detect the seat belt tightness status, achieve multi-position synchronous monitoring, and possess high stability has become an urgent technical problem to be solved.

[0003] A search revealed patent publication number CN212522776U, which discloses a seatbelt alarm device. This seatbelt alarm device is characterized by: a safety belt connected to the middle of the seatbelt; an alarm device located in the middle of the safety belt; a height sensor within the alarm device; the height sensor being connected to a buzzer and a vibrator via wiring; the buzzer being located at the front of the alarm device; and the vibrator at the rear. Retractors are located on both sides of the lower part of the alarm device, one end of which is connected to the height sensor via wiring, and the other end connected to a buckle. Compared to existing technologies, this device equips the seatbelt with a height sensor to monitor its working height in real time. When the height exceeds the safe height, the buzzer will sound an alarm; in noisy environments, the vibrator will vibrate to alert the user; simultaneously, the retractor will tighten the retractor rope to prevent the user from moving further upwards.

[0004] While existing technologies can achieve a certain alarm effect during use, they have the following drawbacks: the lack of synchronous tightening function in existing devices leads to uneven tightness of the seat belts, and the lack of an automatic detection alarm mechanism makes it difficult to detect potential safety hazards in real time. In view of this, we propose a seat belt alarm device that solves the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a seat belt alarm device.

[0006] The technical solution of this utility model is as follows: A seat belt alarm device includes a housing and a rotating ring. A rotating motor is fixedly connected to one outer wall of the housing. The output shaft of the rotating motor is fixedly connected to the rotation center of a rotating column. The rotating column is fixedly connected to the rotating ring. The rotating ring has a mounting groove at its center. The rotating column is located in the mounting groove, and the rotating ring follows the rotating column to rotate along its axis.

[0007] When using one of the seat belt alarm devices in this solution, the belt is wound and fixed in the mounting groove of the hook. The rotating motor is driven to make the rotating ring rotate. After the rotating ring rotates, it drives the hook to move along the guide rail towards the center of the rotating ring, while tightening the installed belt. After tightening, one end of the hook contacts the pressure sensor on the inner wall of the guide rail. If any hook is not tightened in place, the pressure sensor transmits an electrical signal to the buzzer and triggers the alarm.

[0008] Preferably, a plurality of guide rails arranged in a circular array are fixedly connected to one side of the outer wall of the housing. The guide rails are located between the housing and the rotating ring, and the direction of the guide rail trajectory is consistent with the radial direction of one side of the outer wall of the housing.

[0009] Preferably, a protective frame is fixedly connected to one side of the outer wall of the housing, the rotating motor is located inside the protective frame, and the protective frame surrounds the side of the rotating motor.

[0010] Preferably, the housing has a cover on one side, the housing edge has a plurality of second threaded holes arranged in a circumferential array, the cover edge has a plurality of first threaded holes arranged in a circumferential array, and the first threaded holes and the second threaded holes are fixedly connected one-to-one by a connecting strap.

[0011] Preferably, the number of the second threaded holes is equal to the number of the first threaded holes.

[0012] Preferably, the guide rail is connected to one end of the hook, the hook has a fixing groove at one end, a pressure sensor is fixedly connected to the inner wall of one side of the hook, and the movement trajectory of the hook is the same as that of the guide rail.

[0013] Preferably, the rotating ring has multiple guide edges, the number of guide edges of the rotating ring is equal to the number of guide rails, and their positions correspond one-to-one. When the guide edges rotate with the rotating ring, they force the hooks connected to their corresponding guide rails to move.

[0014] Preferably, a buzzer is provided on one side of the outer wall of the cover, and the buzzer can receive electrical signals sent by the pressure sensor.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model, through the design that the number of guide edges of the rotating ring and the guide rail are equal and their positions correspond one-to-one, and with the rotation of the rotating column driven by the rotating motor to drive the rotating ring to rotate synchronously, can realize that multiple hooks can simultaneously tighten the safety belt along the radial trajectory of the guide rail, which solves the problem of inconsistent tightness that traditional safety belts require manual adjustment, and significantly improves the convenience and reliability of wearing.

[0017] Second, based on the first beneficial effect, when the pressure value detected by the pressure sensor of any hook does not reach the preset threshold, the buzzer will immediately sound an alarm, forming a closed-loop monitoring system.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0028] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] Please see Figures 1-5 As shown, this embodiment is a seat belt alarm device, including a housing 3 and a rotating ring 8. A rotating motor 4 is fixedly connected to the outer wall of one side of the housing 3. The output shaft of the rotating motor 4 is fixedly connected to the rotation center of the rotating column 9. The rotating column 9 is fixedly connected to the rotating ring 8. The rotating ring 8 has a mounting groove 15 at its center. The rotating column 9 is located in the mounting groove 15. In use, the rotating motor 4 drives the rotating column 9 to rotate, thereby driving the rotating ring 8 to rotate synchronously, providing a power source for the tightening action of the seat belt.

[0032] Example 2

[0033] Please see Figures 1-5 As shown, this embodiment further includes, based on embodiment 1, a plurality of guide rails 10 arranged in a circular array fixedly connected to one side outer wall of the housing 3. The guide rails 10 are located between the housing 3 and the rotating ring 8. In use, the guide rails 10 provide radial sliding trajectory constraints for the hook 1, ensuring that the hook 1 can move linearly along the radial direction of the housing 3 under the drive of the rotating ring 8, thereby achieving precise tightening of the seat belt.

[0034] A protective frame 5 is fixedly connected to one side of the outer wall of the housing 3. The rotating motor 4 is located inside the protective frame 5. When in use, the protective frame 5 can effectively block the impact or interference of external foreign objects on the rotating motor 4, ensuring the normal operation of the motor, and at the same time preventing personnel from accidentally touching the rotating parts and causing safety hazards.

[0035] A cover 13 is provided on one side of the housing 3. Multiple second threaded holes 11 arranged in a circular array are provided along the edge of the housing 3. Multiple first threaded holes 7 arranged in a circular array are provided along the edge of the cover 13. The first threaded holes 7 and the second threaded holes 11 are fixedly connected one-to-one by a connecting strap 2. In use, the first threaded holes 7 and the second threaded holes 11 are fixed by connecting strap 2 and bolts, and the cover 13 is tightly fixed to the housing 3 to form a closed internal space, protecting the core components of the device and reducing dust and moisture corrosion.

[0036] The number of second threaded holes 11 is equal to that of the first threaded holes 7. During use, the equal number of threaded holes ensures that the connection points between the cover 13 and the housing 3 are evenly distributed, so as to balance the fastening force, avoid loosening of the connection due to stress concentration, and ensure the structural stability of the device.

[0037] The guide rail 10 is connected to one end of the hook 1. The hook 1 has a fixing groove 6 at one end. A pressure sensor 14 is fixedly connected to the inner wall of one side of the hook 1. When in use, the seat belt webbing passes through the fixing groove 6 and connects to the hook 1. When the rotating ring 8 drives the hook 1 to move along the guide rail 10 to tighten the seat belt, the pressure sensor 14 will detect the reaction force on the hook 1 to determine whether the seat belt has reached the preset tightening state.

[0038] The rotating ring 8 has multiple guide edges. The number of guide edges of the rotating ring 8 is equal to that of the guide rail 10, and their positions correspond one-to-one. During use, when the rotating ring 8 rotates, its guide edges contact the mating surface of the hook 1. Through the guiding effect of the curved contour, the circular motion of the rotating ring 8 is converted into the radial linear motion of the hook 1, thereby realizing the function of simultaneously tightening multiple seat belts.

[0039] A buzzer 12 is provided on one outer wall of the cover 13. When in use, when the pressure value detected by the pressure sensor 14 is lower or higher than the safety threshold, it will send an electrical signal to the buzzer 12 to trigger an audible alarm, reminding the user to check the status of the seat belt and ensure safe use.

[0040] Instructions for use: When using this device, the belt is wound and fixed in the mounting groove 15 of the hook 1. The drive motor 4 is used to rotate the ring 8. After the ring 8 rotates, it drives the hook 1 to move along the guide rail 10 towards the center of the ring 8, while tightening the installed belt. After tightening, one end of the hook 1 contacts the pressure sensor 14 on the inner wall of the guide rail 10. If any hook 1 is not tightened properly, the pressure sensor 14 transmits an electrical signal to the buzzer 12 and triggers an alarm. The control system of this device is located inside the vehicle's infotainment system and will not be described in detail here.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
