Description
Technical field
This utility model relates to mobile unit technical field, is especially a kind of weather resistant safety device of vehicle.
Background technology
There is a kind of safety device of vehicle at present, it includes housing, it is arranged on the testing circuit in housing and the ultrasound probe being arranged on outside housing, described ultrasound probe is connected with described testing circuit by holding wire, also include siren, the signal output part of described testing circuit is connected with central processing unit, the outfan of described central processing unit is connected with siren, described housing is provided with installation groove, described installation groove is provided with fixed support, described fixed support is removably connected by two symmetrical supports and forms, described fixed support is provided with elastic spike, although mounting and dismounting all very convenient on car body, decrease safety device of vehicle spoilage in disassembly process, but a spike very thin weakness after all, in vehicle life-time service, fatigue failure easily occurs, and then cause getting loose, break down, change for environment, such as difference variation is more sensitive, weatherability is poor, easily there is the situation that extraneous rainwater penetrates into from the binding face of ultrasound probe and car body to car, fixed support is removably connected by two symmetrical supports and forms simultaneously, structural strength is relatively low, and fixed support is installed on installation groove, and it is fixing for installing the distance between groove and ultrasound probe, therefore the distance between fixed support and ultrasound probe is fixing, the use environment of the distance changed between fixed support and ultrasound probe cannot be met the needs of, adaptability is poor.
Utility model content
Technical problem to be solved in the utility model is, overcomes the defect of prior art, it is provided that a kind of weatherability better, not easily get loose, structural strength is higher, the good weather resistant safety device of vehicle of adaptability.
For solving above-mentioned technical problem, the utility model proposes a kind of weather resistant safety device of vehicle, it includes housing, be arranged in housing testing circuit and the ultrasound probe being arranged on outside housing, ultrasound probe electrically connects with testing circuit, the face offseted that contacts with car body of ultrasound probe is provided with cannelure, cannelure is provided with sealing ring, housing slip cap is connected to fixed support, housing is threaded to be had for the support bracket fastened nut of axial limiting, and housing is arranged with the spring between fixed support and ultrasound probe and the post being set in outside spring.
After adopting said structure, compared with prior art, after this utility model has the advantage that this utility model is arranged on car body, sealing ring realizes sealing waterproof, extraneous rainwater is stoped to penetrate in car from the binding face of ultrasound probe with car body, even if the temperature difference, humidity etc. change greatly, rely on spring and post can play autoregulation, and spring and the weatherability of post own are just better, originate as the primary resilient that this utility model is fixing with spring, post is in protection simultaneously, during guide spring, also provide for the resiliency supported of higher-strength, intensity is higher, reduce the requirement to spring force, spring is made to have increased durability and stability, therefore not easily get loose after overall co-ordination, simultaneously to be not that two parts are removable like prior art be formed by connecting fixed support, but it is overall, therefore structural strength is higher, and support bracket fastened axial location is adjusted by nut, make the distance between fixed support and ultrasound probe adjustable, therefore adaptability is better, the length of post according to this distance go adjust and determine be suitable for install.
As improvement, spring is cylinder stage clip, and so, after this utility model is mounted, what spring presented is compressive state, adopts cylinder stage clip pointed so that this utility model after installing more stable reliably, durability is better.
As improvement, nut is self-locking nut, so, it is prevented that reversion gets loose, it is adaptable to the vibration environments such as vehicle, simultaneously simple in construction.
As improvement, fixed support is the circular slab that middle part sets through hole, and so, processing is simple, and production cost is low, and intensity is high simultaneously.
As improvement, the diameter of circular slab is more than the diameter of nut, and so, nut and circular slab offset completely, and circular slab is fixing more reliable and more stable.

Detailed description of the invention
Below this utility model is described in further detail:
This utility model one weather resistant safety device of vehicle, it includes housing 1, be arranged in housing 1 testing circuit and the ultrasound probe 2 being arranged on outside housing 1, ultrasound probe 2 electrically connects with testing circuit, the contacting, with car body 6, the face offseted and be provided with cannelure of ultrasound probe 2, cannelure is provided with sealing ring 8, housing 1 slip cap is connected to fixed support 3, housing 1 is threaded the nut 4 for axial limiting fixed support 3, and housing 1 is arranged with the spring 5 between fixed support 3 and ultrasound probe 2 and the post 7 being set in outside spring 5.
The shape of cross section of sealing ring 8 is consistent with the shape of cross section of cannelure, such as rectangular cross section, such simple in construction, better tightness.
Post 7 can be plastic column, rubber column etc.
Spring 5 is cylinder stage clip.
Nut 4 is self-locking nut.
Fixed support 3 sets the circular slab of through hole for middle part.
The diameter of circular slab is more than the diameter of nut 4.
This utility model also includes siren, and described siren is provided with the protection device preventing from burning, and the signal output part of described testing circuit is connected with control unit for vehicle, and control unit for vehicle is connected with siren.
This utility model is fixed on car body 6 by post 7, spring 5 by this utility model, namely formed between ultrasound probe 2 and post 7, spring 5 and clamp structure, install by clamping the mode of car body 6, installation and removal are all very convenient, decrease this utility model spoilage in disassembly process. Protection device is possible to prevent siren to burn.
The above is only better embodiment of the present utility model, therefore all equivalences done according to the structure described in present patent application scope, feature and principle change or modify, and are all included in this utility model patent claim.
