Abstract

A shell structure of a signal sensing and transmitting device adapted to be used with a wireless speedometer for a bicycle is provided. A main body of a signal sensing and transmitting circuit and a battery is received within the shell structure. The shell structure includes a shell body including an opening for being inserted therethrough the main body of the signal sensing and transmitting circuit and the battery, and a receiving space for receiving therein the main body of the signal sensing and transmitting circuit and the battery; and a fastening lip for covering the opening of the shell body and fastening the main body of the signal sensing and transmitting circuit and the battery within the shell body.

Claims

1. A shell structure of a signal sensing and transmitting device adapted to be used with a wireless speedometer for a bicycle, wherein a main body of a signal sensing and transmitting circuit and a battery are received within said shell structure, comprising:

a shell body formed into a pillared shape including an opening on a top portion thereof for inserting therethrough said main body of said signal sensing and transmitting circuit and said battery and a receiving space for receiving therein said main body of said signal sensing and transmitting circuit and said battery; and

a fastening cover for covering said opening of said shell body and fastening said main body of said signal sensing and transmitting circuit and said battery within said shell body.

2. A shell structure according to claim 1, wherein said shell body is hollow for forming therein said receiving space.

3. A shell structure according to claim 2, wherein said shell body is cylindrical and said fastening cover is circular.

4. A shell structure according to claim 3 wherein both said shell body and said fastening lip are threaded so that said fastening lip can be screwed on said shell body.

5. A shell structure according to claim 1 wherein a flexible fixer is formed on said shell body, and a recess corresponding to said flexible fixer is formed on said fastening lip for receiving therein said flexible fixer.

6. A shell structure according to claim 1 wherein said shell body and said fastening lip are jointed by a bolt.

7. A shell structure according to claim 1, further comprising a water-resistant ring mounted between said fastening lip and said shell body for keeping said receiving space away from moisture.

8. A shell structure according to claim 7 wherein said water-resistant ring is made of a material selected from one of rubber and silica gel.

9. A shell structure according to claim 7 wherein both said fastening lip and said shell body include threaded portions respectively so that said fastening lip can be screwed on said shell body, and said water-resistant ring is mounted between said threaded portions.

10. A shell structure according to claim 7 wherein said water-resistant ring is mounted around a rim of said opening.

11. A shell structure according to claim 7 wherein said water-resistant ring is mounted at a junction of said shell body and said fastening lip.

12. A shell structure according to claim 1 wherein said main body of said signal receiving and transmitting circuit includes a transmitting antenna, a print circuit board (PCB), and a PCB holder for holding said PCB.

13. A shell structure according to claim 12 wherein a battery supporter is mounted on said PCB holder for supporting said battery.

14. A shell structure according to claim 1 wherein said shell body further includes a fixing ring for fixing said signal sensing and transmitting device on a bicycle.

15. A shell structure according to claim 1 wherein said shell body is formed integrally.
