Description

TECHNICAL FIELD

[0002] Vehicle driving state monitoring is crucial for the safe operation and performance optimization of vehicles.

[0003] Traditional vehicle sensors have played a certain role in monitoring driving state, but their shock resistance and impact resistance are often insufficient when facing complex road conditions and harsh environments.

[0004] During actual vehicle driving, vehicles may experience various degrees of vibration and impact, such as passing through bumpy road surfaces, speed bumps, or encountering collisions. These vibrations and impacts can cause traditional sensors to decrease in accuracy, distort signals, or even be damaged, thereby affecting accurate monitoring of vehicle driving state.

[0005] For example, the Chinese patent with publication number CN209196028U discloses a vehicle-mounted sensor damping device and a car. The damping mechanism is installed in a circumferential distribution around the axis of the first plate body, and the direction of the elastic force or contraction force formed by the damping mechanism forms an angle with the axis of the first plate body at a certain preset angle. Therefore, the vehicle-mounted sensor damping device can resist vibrations and impact forces from different directions.

[0006] In view of the above related technology, during actual vehicle driving, vehicles may experience various degrees of vibration and impact, such as passing through bumpy road surfaces, speed bumps, or encountering collisions.

DETAILED DESCRIPTION

[0028] It is easy to understand that according to the technical scheme of the present application, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the present application, and should not be regarded as the whole or regarded as the limitation or restriction of the technical scheme of the present application.

[0029] In order to further understand the content of the present application, the present application is described in detail in combination with the drawings.

[0030] According to the embodiment of the present application in combination with Figure 1 and Figures 3-4 as well as Figures 6-7The image shows a shock-resistant and impact-resistant vehicle driving status monitoring sensor, including a protective component 2 that filters vehicle vibrations. A vehicle sensor 1 is disposed above the protective component 2. The vehicle sensor 1 is typically based on MEMS technology and uses internal miniature accelerometers and gyroscopes to sense the vehicle's motion status.

[0031] The protective component 2 includes a protective housing 21 for installation and connection with the vehicle. A buffer mechanism 22 is provided in the middle of the inner side of the protective housing 21 to reduce the vibration of the vehicle sensor 1. An impact-resistant mechanism 23 is provided on the outer side of the buffer mechanism 22 to effectively protect the vehicle sensor 1 in the event of a strong instantaneous impact.

[0032] The impact-resistant mechanism 23 includes a cavity ring 231 welded to the inner wall of the protective housing 21. A rubber airbag 232 is glued to and connected to the upper end of the cavity ring 231. The rubber airbag 232 is located directly below the vehicle sensor 1. Cavity plates 233 are symmetrically welded to the inner wall of the cavity ring 231. The cavity plates 233 are connected to the cavity ring 231. A driven plate 234 is slidably mounted on the inner side of the cavity plate 233. The driven plate 234 is fixedly connected to the buffer mechanism 22. During the vibration reduction process, the buffer mechanism 22 simultaneously drives the driven plate 234 to compress the gas in the cavity plate 233. Since the cavity plate 233 is connected to the cavity ring 231, the gas gradually enters the cavity ring 231 from the cavity plate 233. Since the cavity ring 231 is connected to the rubber airbag 232, as the gas increases, the rubber airbag 232 is forced to expand, thus making soft contact with the vehicle sensor 1, thereby improving the overall impact resistance.

[0033] Combination Figure 2 as well as Figure 5 As shown, the buffer mechanism 22 includes a buffer spring 221. Sleeves 222 are fixedly installed at both the upper and lower ends of the buffer spring 221. The sleeve 222 at the lower end of the buffer spring 221 is fixedly connected to the inner wall of the protective shell 21. A groove 11 is provided on the lower end face of the vehicle sensor 1. The sleeve 222 at the upper end of the buffer spring 221 matches the groove 11. The vibration generated by the vehicle during driving is transmitted to the buffer spring 221 through the sleeve 222. The buffer spring 221 effectively filters the vibration through its own deformation, reduces the vibration energy transmitted to the vehicle sensor 1, and thus reduces the probability of damage to the internal components of the vehicle sensor 1.

[0034] Combination Figure 2 as well as Figure 5As shown, the surface of the groove 11 is circumferentially arranged with a plurality of sliding grooves 12, the outer wall of the sleeve 222 at the upper end of the buffer spring 221 is circumferentially arranged and fixedly installed with a plurality of sliding rails 223, the sliding rails 223 are in sliding connection with the sliding grooves 12, and in the deformation process of the buffer spring 221, the sleeve 222 moves up and down in the groove 11, and the sleeve 222 drives the sliding rails 223 to slide in the sliding grooves 12 at the same time, so that the buffer spring 221 is restricted and can only deform vertically, thereby avoiding the buffer spring 221 from being twisted, and further improving the service life of the buffer spring 221.

[0035] In combination Figure 5 As shown, the inner wall of the sleeve 222 at the lower end of the buffer spring 221 is fixedly installed with a cavity cylinder 224, and the inner wall of the sleeve 222 at the upper end of the buffer spring 221 is fixedly installed with a driven rod 225. The lower end of the driven rod 225 is fixedly installed with a driven disc 226, the outer wall of the driven disc 226 is tightly combined with the inner wall of the cavity cylinder 224, a plurality of through holes 227 are penetratingly formed in the inside of the driven disc 226, in the vertical deformation process of the buffer spring 221, the sleeve 222 pushes the driven rod 225 downward, and the driven rod 225 pushes the driven disc 226 to move. Since the inside of the cavity cylinder 224 is filled with damping liquid, the damping liquid passes through the plurality of through holes 227 to form a damping effect, which can effectively prevent the buffer spring 221 from resonating with the vehicle and ensure effective damping effect.

[0036] In combination Figures 2-3 As shown, the outer wall of the protective shell 21 is symmetrically fixedly installed with a connecting lug one 212, the outer wall of the vehicle sensor 1 is symmetrically formed with a sliding groove two 13, the surface of the sliding groove two 13 is slidingly provided with a connecting lug two 14, the upper end of the connecting lug two 14 is fixedly installed with an extension rod 15, the upper end of the extension rod 15 is fixedly connected with the surface of the sliding groove two 13, the outer side of the extension rod 15 is sleeved with a spring 16, the upper end of the spring 16 is fixedly connected with the surface of the sliding groove two 13, and the lower end of the spring 16 is fixedly connected with the connecting lug two 14. During installation, the connecting lug one 212 and the connecting lug two 14 are corresponded one by one, and the bolt is screwed on, which is convenient to operate. In the vertical deformation process of the buffer spring 221, the vehicle sensor 1 as a whole also moves downward, and since the protective shell 21 is fixedly installed in the vehicle, the connecting lug one 212 pushes the connecting lug two 14 to extrude the spring 16, thereby achieving a two-stage buffering effect and further improving the damping performance.

[0037] In combination Figure 3 As shown, the outer wall of the protective shell 21 is symmetrically fixedly installed with a connecting lug three 211, which is corresponded with the mounting hole of the vehicle and connected through a bolt, which is convenient to operate and facilitates subsequent disassembly, maintenance or replacement.
