    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • With reference to FIGS. 1 to 3 and 9, a parking sensor device in accordance with the present invention may be mounted on a bumper of a vehicle and comprises a casing 10, a front cover 20, a sensor module 30, a circuit board 40, an assembling clamp 50 and a cable assembly 60.
  • The casing 10 has a top, a bottom, a front, a rear, a sleeve 11, a cavity 100, two first hooking elements 12, 13, a chamber 101, an opening 105, multiple fastening elements 14 and a cap 15.
  • The sleeve 11 is formed on the front of the casing 10 and has multiple positioning recesses 111 defined in a front end of the sleeve 11.
  • The cavity 100 is defined in and surrounded by the sleeve 11 of the casing 10.
  • The first hooking elements 12, 13 are formed respectively on the top and the bottom of the casing 10.
  • The chamber 101 is defined in the casing 10.
  • The opening 105 is defined through the casing 10 close to the rear and communicates with the chamber 101.
  • The fastening elements 14 are formed on and protrude from the casing 10.
  • The cap 15 is mounted detachably on the opening 105 so that the opening 105 may be covered by the cap 15. The cap 15 has multiple fastening tabs 151 formed on and protruding from the cap 15 and corresponding to the fastening elements 14. Each fastening tab 151 has a fastening hole 152 defined through the fastening tab 151 and engaging a corresponding fastening element 14.
  • The front cover 20 is mounted on the front of the casing 10 and has a through hole 200 defined through the front cover 20.
  • The sensor module 30 is mounted in the cavity 100 of the casing 10 and the through hole 200 of the front cover 20. The sensor module 30 may be an ultrasonic sensor module and may have a mounting bracket 31 and an ultrasonic transducer 35.
  • The mounting bracket 31 is mounted in the sleeve 11 of the casing 10 and has an inner space 310 and multiple positioning protrusions 311. The inner space 310 is defined in the mounting bracket 31. The multiple positioning protrusions 311 are formed on and protrude radially from the mounting bracket 31 and respectively engaging the positioning recesses 111 of the casing 10.
  • The ultrasonic transducer 35 is mounted in the inner space 31 of the mounting bracket 31.
  • The circuit board 40 is mounted in the chamber 101 of the casing 10 and is connected electrically to the sensor module 30. The circuit board 40 may have electric components such as a central process unit and a random access memory to process signals from the sensor module 30.
  • With further reference to FIG. 4, the assembling clamp 50 detachably engages the rear of the casing 10 and has a mounting space 500 and may further have a base board 51, two extension boards 52, 53 and two slots 56.
  • The mounting space 500 is defined in the assembling clamp 50, detachably engages the rear of the casing 10, and has an inner surface and two second hooking elements 521, 531. The second hooking elements 521, 531 are formed on the inner surface of the mounting space 500, are opposite to each other, and selectively hook the first hooking elements 12, 13 of the casing 10 respectively. When the casing 10 enters the mounting space 500 of the assembling clamp 50, the first hooking elements 12, 13 move across and respectively hook the second hooking elements 521, 531 to prevent the casing 10 from falling out of the assembling clamp 50.
  • The extension boards 52, 53 are formed oppositely on and protrude respectively from two ends of the base board 51. The mounting space 500 is defined among the base board 51 and the extension boards 52, 53. The second hooking elements 521, 531 are formed respectively on the extension boards 52, 53. Furthermore, each extension board 52, 53 may further have two limiting guides 525, 535 formed on the extension board 52, 53. When the casing 10 enters the mounting space 500 of the assembling clamp 50, the casing 10 is limited to move between the two limiting guides 525, 535 of each extension board 52, 53 without laterally falling out of the assembling clamp 50.
  • Each slot 56 is defined through the base board 51 and one of the extension boards 52, 53 of the assembling clamp 50 to make the extension boards 52, 53 of the assembling clamp 50 light-weighted and slightly resilient for deformation, thereby facilitating hooking the first hooking elements 12, 13 to the second hooking elements 521, 531.
  • The casing 10 and the assembling clamp 50 are engaged quickly with each other through the first hooking elements 12, 13 and the second hooking elements 521, 531, thereby facilitating the easy fabrication of the parking sensor device and improving the convenience of maintenance of the parking sensor device. Furthermore, the assembling clamp 50 covers the casing 10 and the cap 15 to improve the combination strength of the casing 10 and the cap 15 so increasing the whole structural strength of the parking sensor device.
  • Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
