Technical Field

[0001] The utility model relates to the technical field of protective cases, and particularly relates to a protective case for an ultrasonic measurement module. Background Art

[0002] In order to avoid the ultrasonic measurement module from being knocked and extended its service life, a protective case is generally installed on its outer peripheral side.

[0003] The traditional protective case is mainly composed of an upper cover and a lower cover. The upper cover is detachably snapped onto the lower cover and defines a receiving cavity between the upper cover and the lower cover. The front end and the rear end of the upper cover and the lower cover are respectively provided with through holes communicating with the receiving cavity. The ultrasonic measurement module is inserted into the receiving cavity and its front end and rear end respectively pass through the corresponding through holes. Although the above-mentioned protective case can be wrapped around the outer peripheral side of the ultrasonic measurement module to protect the ultrasonic measurement film group, in actual use, there are mainly the following problems: ① The upper cover and the lower cover are not firmly snapped together and often shake, affecting the use state of the ultrasonic measurement module; ② The shape difference between the receiving cavity defined by the upper cover and the lower cover and the shape of the ultrasonic measurement module is relatively large, often causing the ultrasonic measurement module to shake and affecting the measurement result; ③ The ineffective sound waves generated by the ultrasonic measurement module often flow back to the main sound path, affecting the final measurement result.

[0004] Therefore, how to design a protective case for an ultrasonic measurement module with firm snap connection, not easy to shake and capable of preventing ineffective sound waves from returning to the main sound path is an urgent problem to be solved by those skilled in the art.

The upper end of the ultrasonic measurement module has a plurality of upper mating surfaces and its lower end has a plurality of lower mating surfaces. The protective case includes an upper cover body and a lower cover body.

[0007] The lower end of the upper cover body is detachably connected to the upper end of the lower cover body and defines a receiving cavity between the upper cover body and the lower cover body. The front end and the rear end of the upper cover body and the lower cover body are both provided with through holes communicating with the receiving cavity. The ultrasonic measurement module is inserted into the receiving cavity and its front end and rear end respectively extend out of the corresponding through holes. The lower end of the upper cover body has a plurality of upper conforming surfaces and the plurality of upper conforming surfaces respectively press against the plurality of upper mating surfaces. The upper end of the lower cover body has a plurality of lower conforming surfaces and the plurality of lower conforming surfaces respectively abut against the plurality of lower mating surfaces.

[0008] The beneficial effects of the present utility model are as follows: The structure of the protective case of the traditional ultrasonic measurement module is improved. First, a plurality of upper conforming surfaces are provided at the lower end of the upper cover body, and the plurality of upper conforming surfaces can be used to conformally press against a plurality of upper mating surfaces; then, a plurality of lower conforming surfaces are provided at the upper end of the lower cover body, and the plurality of lower conforming surfaces can be used to conformally abut against a plurality of lower mating surfaces, so as to conformally wrap the outer peripheral side of the ultrasonic measurement module, protect the ultrasonic measurement module, prevent the ultrasonic measurement module from shaking, and improve the accuracy of the measurement result of the ultrasonic measurement module.

[0010] Further, a plurality of card holes are provided on the inner side surface of the upper cover body; a plurality of buckles are fixed on the inner bottom surface of the lower cover body, and the plurality of buckles are respectively detachably clamped in the plurality of card holes.

[0011] The beneficial effect of adopting the above is: By respectively detachably clamping the plurality of buckles in the plurality of card holes, the firmness of the clamping between the upper cover body and the lower cover body can be improved, and the convenience of separating the upper cover body and the lower cover body can also be improved.

[0012] Further, the plurality of buckles are all made of elastic materials.

[0013] Further, it further includes a positioning block for connecting with the ultrasonic measurement module, and the positioning block is fixed on the inner bottom surface of the lower cover body.

[0014] Further, the bottom surface of the lower cover body is provided with positioning post holes for connecting with other components.

[0015] The beneficial effect of adopting the above is: By vertically fixing the positioning post on the outer bottom surface of the lower cover body, it can facilitate positioning in subsequent process or subsequent application installation.

[0016] Further, it further includes a plurality of upper anti-scattering plates and lower anti-scattering plates for preventing ineffective sound waves from flowing back to the main sound path. The plurality of upper anti-scattering plates are spaced and fixed on the inner top surface of the upper cover body; the plurality of lower anti-scattering plates are spaced and fixed on the inner bottom surface of the lower cover body.

[0017] The beneficial effect of adopting the above is: By respectively fixing the upper anti-scattering plate and the lower anti-scattering plate on the inner top surface of the upper cover body and the inner bottom surface of the lower cover body, it can effectively prevent ineffective sound waves from flowing back to the main sound path and improve the accuracy of the measurement of the ultrasonic measurement module.
