Description
Technical Field
The utility model relates to the technical field of tire detection, in particular to a camera fixing device for tire pattern depth detection.
Background
The common tyre pattern measuring instrument in the market mostly adopts a manual measuring mode, namely a depth gauge is used for measuring, but the measuring method has low efficiency, large influence of human factors and obvious error. So the MEMS-3D camera is used for detection at present, but the existing camera detection has high efficiency and cannot be influenced by human factors, but illumination cannot be avoided in the camera detection, and the illumination can influence the detection precision; the MEMS-3D camera is integrated with an infrared light source, is independent of an external light source, can be used for 3D measurement, and can be used for measuring tire patterns, but can only perform non-contact measurement due to small gaps among the tire patterns, namely the gaps are insufficient for placing a camera of the 3D camera, but if the distance measurement is performed, a distance exists between the camera of the 3D camera and the tire patterns, and the distance is interfered by the external light source, so that the measurement result is affected. There is an urgent need for a camera fixing device that is not affected by external light.
Disclosure of Invention
In order to solve the above problems in the prior art, the present utility model provides a camera fixing device for detecting the depth of a tire pattern.
The utility model discloses a camera fixing device for detecting tire pattern depth, which comprises a fixing block, wherein the inside of the fixing block is in a hollow state, one end of the fixing block is in an arc surface, the other end of the fixing block is fixedly connected with a bump, and a camera mounting groove communicated with the inside of the fixing block is arranged on the bump;
wherein the cambered surface is a transparent surface.
Preferably, the cambered surface is attached to the radian of the tire.
Preferably, the periphery of the protruding block is provided with a supporting rib connected with the fixing block.
Preferably, the fixing block and the bump are integrally formed.
Compared with the prior art, the utility model has the beneficial effects that:
the structure of the utility model enables the light path of the camera to pass through the transparent cambered surface only, and the cambered surface is matched with the radian of the tire, so that the camera cannot be influenced by external illumination, and the detection accuracy of the camera is improved.

FIG. 1 is a schematic view of a camera fixture for tire tread depth detection according to the present utility model.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model is described in further detail below with reference to the attached drawing figures:
referring to fig. 1, the utility model provides a camera fixing device for detecting tire pattern depth, which comprises a fixing block 1, wherein the inside of the fixing block 1 is in a hollow state, one end of the fixing block 1 is in an arc surface 11, the other end of the fixing block is fixedly connected with a bump 2, and a camera mounting groove 21 communicated with the inside of the fixing block 1 is arranged on the bump 2;
wherein the cambered surface 11 is a transparent surface, i.e. the rest surface is an opaque surface.
Specifically, the arcuate surface 11 conforms to the tire arc. I.e. different cambered surfaces 11 are arranged according to the radian of the tire on the market, such as the radian of a 16 inch tire which is common in the market. The camera mounting slot 21 is compatible with the MEMS-3D camera used, i.e. allows the inserted camera to be stable and not sloshing, plug and play.
Further, the circumference of the bump 2 is provided with a support rib 3 connected with the fixing block 1. The support rib 3 is used for sharing the weight of the camera borne by the bump 2, so that the camera stability is improved and the durability is improved.
In this embodiment, the fixing block 1 and the bump 2 are integrally formed. That is, the material of the fixing block 1 is the same as that of the bump 2, and each surface is processed later, so that the cambered surface 11 is transparent, and the other surfaces are opaque. For example, the fixing block 1 and the bump 2 are made of opaque metal, the cambered surface 11 is communicated with the inside, and transparent materials (transparent silica gel, acrylic, etc.) are arranged on the cambered surface 11, and the fixing block 1 and the bump 2 can be made of other materials. Through the above structure, after the camera is inserted into the camera mounting groove 21, the camera is connected with the computer, and the detection program is used to realize the detection of the tire pattern depth (this is the prior art and is not described in detail here), and the camera is not affected by external light during the detection process, so that the detection precision is improved.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
